Description

Technical Field

[0002] Borehole camera testing is a non-destructive testing technology widely used in the field of engineering construction. It is mainly used for visually and accurately detecting and evaluating the internal structure, state, and potential problems of boreholes. The main purpose of borehole camera testing is to take pictures of the inside of the borehole through a high-definition camera to obtain image data of the inside of the borehole, and then analyze the integrity of the borehole, whether there are defects such as cracks, displacements, fractures, etc., the stability of the borehole wall, and the situation of groundwater, leakage sources, etc. The borehole camera testing device mainly consists of two major parts: a camera and a ground controller device. The two are connected by a transmission wire or other communication methods to ensure real-time data transmission and control. The working principle of the borehole camera testing device is based on the optical imaging principle. The image information inside the borehole is captured by the lens and converted into an electrical signal, and then transmitted to the ground controller through a cable or wireless communication method for display and processing. The borehole camera testing device is an important non-destructive testing technical means and plays an important role in multiple fields.

[0025] Referring to Figure 1 , Figure 2 and Figure 3 , the clamping assembly 63 includes positioning rods 631, a top plate 632, a second clamping plate 633, and push springs 634.

The number of fixing rods 721 is two, and they are both arranged at the front side of the upper end inside the placement groove 71. The front ends of the two fixing rods 721 are fixedly connected to the front surface inside the placement groove 71.

The clamping groove 724 is formed at the upper end of the rear surface of the clamping head 722 and penetrates the clamping head 722. The travel groove 725 is formed at the lower end of the left surface of the clamping head 722.

[0030] With the above solution: By setting the locking head assembly 72, it is used to clamp and connect the connection head 8 fixed to the lower surface of the second clamping plate 633, and further play a role in fixing the clamped second clamping plate 633.

[0031] Reference Figure 4 , the control assembly 73 includes a rotating rod 731, a rotating handle 732, a pressing rod 733 and a knob 734. The rotating rod 731 is arranged at the lower front side of the clamping head 722 and is rotatably connected to the left and right ends inside the placement groove 71 respectively. The left end of the rotating rod 731 extends out of the placement groove 71 and is rotatably connected to the first clamping plate 62. The rotating handle 732 is sleeved on the left end surface of the rotating rod 731 and is fixedly connected to the rotating rod 731.

[0033] Reference Figure 3 , connectors 8 are arranged at both the left and right ends of the lower surface of the second clamping plate 633, and both connectors 8 are fixedly connected to the second clamping plate 633.

[0034] Adopting the above solution: By arranging connectors 8 at both the left and right ends of the lower surface of the second clamping plate 633, which are used to cooperate and clamp with the two clamping components 63, thereby fixing the second clamping plate 633 and keeping the second clamping plate 633 stable for the transmission wire 4.

[0035] The working principle of the present utility model:

[0036] When assisting in stabilizing the transmission wire 4 and the connection end 3, by rotating the knob 734 to drive the rotating rod 731 to rotate. While the rotating rod 731 rotates, it drives the rotating handle 732 to rotate. While the rotating handle 732 rotates, it drives the pressing rod 733 to move and press against the inner wall of the stroke groove 725 in the stroke groove 725, so that the clamping head 722 is squeezed forward on the surface of the fixed rod 721, and at the same time, the spring 723 is squeezed. The movement of the clamping head 722 causes the card slot 724 to disengage from the connector 8, thereby releasing the clamping of the connector 8 and releasing the fixation of the second clamping plate 633. Then, the second clamping plate 633 is pulled on the surface of the positioning rod 631, and while pulling, the push spring 634 is squeezed. Then, the transmission wire 4 is passed through between the first clamping plate 62 and the second clamping plate 633 to be connected to the connection end 3. Then, the transmission wire 4 is smoothed out and placed in the first clamping plate 62. Then, the second clamping plate 633 is released, and the push spring 634 will rebound to push the second clamping plate 633 downward and cooperate with the first clamping plate 62 to clamp and stabilize the transmission wire 4. At the same time, when the second clamping plate 633 moves downward to clamp, it will drive the connectors 8 on both sides of the lower surface to insert into the placement groove 71 and squeeze against the clamping head 722, causing the clamping head 722 to move forward on the surface of the fixed rod 721 and squeeze the spring 723. After the second clamping plate 633 moves to completely clamp and stabilize the transmission wire 4, the connector 8 will move to correspond to the card slot 724. At the same time, the clamping head 722 is no longer squeezed, and the spring 723 will rebound to push the clamping head 722 backward, so that the clamping head 722 is sleeved on one side of the connector 8 through the card slot 724, thereby clamping the connector 8 and fixing the second clamping plate 633, thus completing the auxiliary stabilization of the transmission wire 4 and the connection end 3.

[0037] In summary, the auxiliary component for drilling video testing solves the problem of the existing drilling video testing device in which the connection between the connection end of the observer and the conductive line is not stable and is usually weak, so that the conductive line is pulled by its own weight for a long time and twisted and dragged when the equipment is used, which will cause the connection between the conductive line and the connection end to become loose or even disconnected, thus causing the problem of conveying equipment.
