Abstract

The utility model relates to a transmitting and receiving integrated coil of a mining transient electromagnetic instrument. The integrated coil comprises a transmitting coil, a receiving coil, a rubber sleeve and a four-core waterproof connector. The transmitting coil and the receiving coil are parallelly arranged in the rubber sleeve and combined into an integral coil, a connector of the transmitting coil and a connector of the receiving coil are integrated and plugged into the four-core waterproof connector, the edge of the inner side of the four-core waterproof connector is provided with two trapezoid protrusions having direction guiding effect, and the transmitting coil and the receiving coil consist of multi-core cables. The transmitting coil and the receiving coil are combined into a whole, the overall volume of the coil is decreased, carrying, movement and connection of the coil and an instrument are facilitated, the waterproof connector adopted by the coil connectors can effectively prevent short circuit caused by the fact that water enters the coil connectors, and great convenience is brought for people in use.

Description

The emission of mine transient electromagnetic instrument receives the integral type coil
Technical field
The utility model relates to the coil that receives and transmit under a kind of mine, and the emission of the especially convenient mine transient electromagnetic instrument that is connected with instrument receives the integral type coil.
Background technology
In recent years, water bursting in mine causes casualties and the accident of property loss occurs again and again.Mine Transient Electromagnetic Method is because little, the high efficiency of bulk effect, high to resolution and the sensitive advantage of post non of low resistance body is widely used in water-bursting predicting and the advanced prediction of mine in length and breadth.At present, being applied to the transmitting coil of the Transient Electromagnetic Apparatus under the mine and receiving coil mostly is homemade polycore cable coiling and forms, and transmitting coil and receiving coil are separated, two coils need to be bundled during use and be fixed, because down-hole limited space, coil is in assembling and put in the process very inconveniently, and coil is subject to excess surface water with the interface of Transient Electromagnetic Apparatus and soaks and cause short circuit.
The utility model content
Assembling and putting problem very inconvenient in the process in order to overcome the coil that receives under the existing mine and transmit, the utility model provides a kind of emission of mine transient electromagnetic instrument to receive the integral type coil, this integral type coil is as a whole with transmitting coil and receiving coil combination, reduced the volume of coil integral body, be convenient to carrying mobile be connected instrument, the waterproof port that coil interface adopts can effectively avoid the coil interface water inlet to be short-circuited, and brings great convenience for people's use.
The technical scheme that its technical matters that solves the utility model adopts is: this integral type coil comprises transmitting coil, receiving coil, rubber sleeve and four-core waterproof port; This transmitting coil is parallel with receiving coil to be placed in the rubber sleeve, make up as a whole coil, the interface of transmitting coil and the interface of receiving coil are integrated and are plugged in the four-core waterproof port, the inside edge of four-core waterproof port is provided with two trapezoidal projections that play the direction effect, and transmitting coil and receiving coil form by polycore cable.During use, arranged clockwise at inboard four cables of four-core waterproof port sequentially is that transmitting coil positive pole, receiving coil negative pole, transmitting coil negative pole and receiving coil are anodal, then the interface Corresponding matching with cable inserts in the four-core waterproof port, the four-core waterproof port is connected the emission, reception and the processing that get final product settling signal with Transient Electromagnetic Apparatus again.。
The beneficial effects of the utility model are, it is as a whole with transmitting coil and receiving coil combination that the emission of this mine transient electromagnetic instrument receives the integral type coil, reduced the volume of coil integral body, be convenient to carrying mobile be connected instrument, the waterproof port that coil interface adopts can effectively avoid the coil interface water inlet to be short-circuited, and brings great convenience for people's use.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is one-piece construction principle schematic of the present utility model.
Fig. 2 is four-core waterproof port front schematic view of the present utility model.
Among the figure, 1. rubber sleeve, 2. receiving coil, 3. transmitting coil, 4. four-core waterproof port, 5. trapezoidal projection, 6. receiving coil negative pole, 7. transmitting coil negative pole, 8. transmitting coil is anodal, and 9. receiving coil is anodal.
Embodiment
In the drawings, this integral type coil comprises transmitting coil 3, receiving coil 2, rubber sleeve 1 and four-core waterproof port 4; This transmitting coil 3 and receiving coil 2 parallel being placed in the rubber sleeve 1, make up as a whole coil, the interface of the interface of transmitting coil 3 and receiving coil 2 is integrated and is plugged in the four-core waterproof port 4, the inside edge of four-core waterproof port 4 is provided with two and plays the trapezoidal protruding 5 of direction effect, and transmitting coil 3 and receiving coil 2 form by polycore cable.During use, arranged clockwise at four-core waterproof port 4 inboard four cables sequentially is transmitting coil positive pole 8, receiving coil negative pole 6, transmitting coil negative pole 7 and receiving coil positive pole 9, then the interface Corresponding matching with cable inserts in the four-core waterproof port 4, four-core waterproof port 4 is connected the emission, reception and the processing that get final product settling signal with Transient Electromagnetic Apparatus again.
