When the wire is pulled, the joint is often torn apart, the wire is open-circuited, the field construction data acquisition is interrupted, data is lost, remeasurement is required, wasting manpower, material resources, and financial resources, and delaying the construction progress.

[0023] The present utility model will be described in detail below with reference to the accompanying drawings.

[0024] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0025] Embodiment 1

[0026] As Figure 1 shown, the commonly used method in field construction of geophysical prospecting is to connect the wire ends with adhesive tape or self-made banana connectors. Once the wire is pulled by an external force, the joint is often torn apart, the wire is broken, the field construction data acquisition is interrupted, data is lost, re-measurement is required, wasting manpower, material resources and financial resources, and delaying the construction progress.

[0027] Figure 2 shows a wire joint fixing device for geophysical prospecting construction, including: a clamping part 10, which includes a groove 101 for accommodating a part of the wire containing the wire joint; one side of the groove 101 is coupled to a compression spring 103, and the compression spring 103 is configured to expand the groove 101 under pressure and restore to clamp the part of the wire including the wire joint.

[0028] The wire joint fixing device further includes a detachable part 20, which includes a first surface provided on the bottom surface of the clamping part 10 and a second surface provided on the carrier, and the first surface and the second surface are detachably connected. It is easy to think that various mechanical structures or materials with adhesive properties can achieve the function of such a detachable part 20. For example, mechanical structures such as mortise and tenon structures and snap-fit structures, or magic tapes or adhesive surfaces.

[0029] Refer to Figure 3 , the detachable part 20 is a magic tape, and its first surface and second surface are respectively opposite sub-surfaces or mother-surfaces. The back surface of the first surface is fixed to the bottom surface of the clamping part 10 through a tape, and the back surface of the second surface is fixed to the surface of the carrier through a carrier fixing part 30 using a tape (such as 3M brand tape). The magic tape has good reusability. Compared with mechanical detachable or other material-based methods to achieve detachable functions, the magic tape has the advantages of convenience and reusability. Since the position of the wire joint is random and its carrier is also random, the wire joint can be conveniently fixed at the nearest carrier through the magic tape, and only a carrier fixing part 30 for fixing one surface of the magic tape needs to be provided at the carrier.

[0030] Refer to Figure 4, a pressing part 102 is arranged on the side surface of the clamping part 10, which is associated with one end of the compression spring 103 close to the groove 101 to realize the compression or restoration of the compression spring 103.

[0031] The compression spring 103 includes 3 groups of compression springs 103 evenly distributed perpendicular to one side of the groove 101. The pressing part 102 includes a first pressing part 102 and a second pressing part 102 arranged on both sides of the clamping part 10, jointly controlling the compression or restoration of all the compression springs 103 in the compression spring 103 groups.

[0032] See Figure 5 , insulating and anti-slip components 104 are arranged on two side surfaces of the groove 101 facing the inside of the groove to enhance the fixing performance of the device for the wire joint.

[0033] Such as Figures 6-7 , the wire joint fixing device as a whole is a wire clamping system using a compression spring 103. When not clamping the wire, it is in a closed state. By pressing the pressing part 102, the opening of the groove 101 is opened, and the wire is placed in it; when the pressing part 102 is released, one side of the groove 101 is restored to close the opening of the groove 101, completing the wire fixing. The whole device shell is made of plastic, insulating to prevent wire leakage, and rubber is used at the contact with the wire to increase the friction force and protect the wire shell at the same time.

[0034] In addition, the carrier platform serving as the carrier of the wire joint fixing device has a flat surface or a concave-convex surface. The flat surface is such as on the outer shell of the instrument and equipment, on the outer shell of the pole tank, or on the horizontal ground next to the measurement point, etc.; in addition, when the carrier platform has a concave-convex surface such as an uneven ground, the back surface of the second surface serving as the carrier platform fixing part 30 has terrain adaptability, for example, a shape-plastic material with adhesive performance.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
