Description

Technical Field

[0001] This utility model relates to the field of engineering surveying, specifically a data acquisition coil with an improved structure. Background Technology

[0002] In tunnel / roadway construction, advanced geological prediction methods are often used to reduce engineering risks and ensure construction safety. Transient electromagnetic method (TEM), as an advanced geological prediction method, is widely used due to its ability to accurately detect water-bearing structures ahead of tunnels / roadways and its high accuracy rate, thus safeguarding the safety of tunnel / roadway construction.

[0003] The commonly used working devices for transient electromagnetic methods in tunnels / roadways are mainly of two types: overlapping loop and dipole-dipole. The overlapping loop device has strong response to geological anomalies and is convenient to construct.

[0004] However, existing data acquisition coils require two workers to hold one side and pull to open it, which is time-consuming and wastes manpower and resources. Furthermore, in narrow tunnels / tunnels, two workers working together are prone to being scraped and bumped against the tunnel / tunnel walls. Therefore, there is an urgent need to provide a data acquisition coil with an improved structure to overcome the shortcomings of current practical applications. Utility Model Content

[0029] The present invention will be further explained below with reference to specific embodiments.

[0030] Please see Figures 1-6 This utility model provides a data acquisition coil with an improved structure. The improved data acquisition coil has four T-junctions 3, four gear adjustment connectors 4, and a data cable 7. The two ends of the T-junctions 3 are respectively fixedly installed with a first horizontal tube 2 and a second horizontal tube 26. The ends of the two second horizontal tubes 26 away from the T-junctions 3 are fixedly connected by the gear adjustment connectors 4. The bottom of the T-junctions 3 is fixedly installed with a vertical tube 5. The two vertical tubes 5 are fixedly connected by the gear adjustment connectors 4. The outer side of the end of the first horizontal tube 2 away from the T-junctions 3 is fitted with a tube sleeve buckle 1. The data cable 7 is wound around the outside of the bracket along the first horizontal tube 2 and the second horizontal tube 26, and the data cable 7 is fixedly connected to the first horizontal tube 2 by the tube sleeve buckle 1. The data cable 7 is wound around the outside of the bracket in a rectangular shape.

[0031] In this embodiment of the utility model, the two vertical tubes 5 are fixedly installed in the middle of the inside of the bracket, so one worker can hold it with both hands, which can reduce the number of workers required for surveying. The gear adjustment connector can be rotated to adjust the length and width of the bracket.

[0032] In one embodiment of this utility model, please refer to Figures 1-6The first horizontal tube 2 has a first external thread 8 on both outer sides and is hollow. The first horizontal tube 2 has a first threaded through hole 9 on both sides of both ends. The tee 3 is hollow and has a first internal thread 10 on the inner side of each of the three branch tubes. The tee 3 has a second threaded through hole 11 on both sides of each of the three branch tubes. The second horizontal tube 26 has the same structure as the first horizontal tube 2. One end of the first horizontal tube 2 and one end of the second horizontal tube 26 are threaded into the branch tube of the tee 3 and the two sides are connected by screw threads. The length of the second horizontal tube 26 is less than the length of the first horizontal tube 2. In this scheme, the first horizontal tube 2 and the second horizontal tube 26 are hollow, made of plastic, lightweight and easy to use. After the first horizontal tube 2 and the second horizontal tube 26 are threaded into the tee 3, they are fixed by screws.

[0033] The gear adjustment connector 4 includes two sleeves 13 and an adjustment gear 12. The closed ends of the two sleeves 13 are rotatably connected by the adjustment gear 12. A knob 14 is provided on one side of the adjustment gear 12. The inner side of the open end of the sleeve 13 is provided with a second internal thread 24 and the two sides of its open end are provided with a fourth threaded through hole 25. The knob 14 is triangular wheel shaped. The angle between the two sleeves 13 can be adjusted by the adjustment gear 12. The knob 14 facilitates the rotation of the adjustment gear 12.

[0034] Both ends of the vertical pipe 5 are provided with a second external thread 23. One end of the vertical pipe 5 is threaded to the sleeve 13 and the other end is threaded to the bottom branch pipe of the tee 3. The end of the second horizontal pipe 26 away from the tee 3 is threaded to the sleeve 13. The vertical pipe 5 and the sleeve 13 and the second horizontal pipe 26 and the sleeve 13 are both fixedly connected by screws. The two vertical pipes 5 form a long straight pipe. The two long straight pipes are easy to hold. In this scheme, the two ends of the two vertical pipes 5 are connected to the tee 3 and the sleeve 13 respectively, and the horizontal support is provided.

[0035] One side of the sleeve buckle 1 is smooth and the other side has an arc-shaped groove 16. The first horizontal tube 2 is snapped into the inside of the arc-shaped groove 16. One end of the sleeve buckle 1 with the arc-shaped groove 16 is rotatably installed with an arc-shaped clamping plate 17. The other end of the sleeve buckle 1 with the arc-shaped groove 16 is provided with a protrusion 18. The arc-shaped clamping plate 17 and the protrusion 18 are snapped into each other. The data cable 7 is snapped between the arc-shaped clamping plate 17 and the first horizontal tube 2. In this scheme, the inner diameter of the data cable 7 and the arc-shaped groove 16 are the same as the outer diameter of the cross section of the first horizontal tube 2. The two are snapped into each other. The data cable 7 is snapped between the arc-shaped clamping plate 17 and the first horizontal tube 2.

[0036] The sleeve buckle 1 has a third threaded through hole 19 in the middle, which corresponds to the first threaded through hole 9 and both are threaded with fastening bolts 15 in sequence. The sleeve buckle 1 has an expansion tube 20 in the middle on the side away from the arc groove 16. The sleeve buckle 1 is fixedly connected to the first horizontal tube 2 by the fastening bolts 15. This design of the sleeve buckle 1 being fixedly connected to the first horizontal tube 2 by the fastening bolts 15 prevents it from falling off and makes it more secure.

[0037] The vertical tube 5 has a long groove 21 in the middle of its back. A glove 6 is fitted on the outside of the vertical tube 5. An adjusting bolt 22 is threaded in the middle of the back of the glove 6. Several annular grooves are evenly distributed on the outside of the glove 6. Rotating the adjusting bolt 22 abuts against the inside of the groove 21 to fix it. The height of the glove 6 is adjustable. The annular grooves on the outside of the glove 6 increase friction and prevent slipping.

[0038] Working principle: When using this utility model, after assembling the bracket, the data cable 7 is wrapped around the outside of the bracket and fixed at the four corners of the bracket by the tube sleeve buckle 1. The height of the handle 6 is adjusted according to the actual situation of the staff. Then, the staff holds the two handle 6 with both hands to open the bracket. By rotating the end and middle of the gear adjustment connector 4, the width and height of the bracket can be adjusted according to the size of the tunnel, making it more convenient to use.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
