Abstract
Description
Technical Field
[0001] This utility model relates to the field of low-voltage engineering testing technology, specifically to a low-voltage engineering circuit testing device. Background Technology
[0002] Existing technologies, such as CN116256598U, disclose a line monitoring system and method for low-voltage engineering. In use, a rack is suspended from the low-voltage engineering line via pulleys. A pressure-boosting mechanism adjusts the friction between the pulleys and the line to prevent the rack from slipping. A servo motor is controlled to move the entire rack. During this movement, a camera captures images of the low-voltage engineering line. After capturing the images, the data is encoded by a data encoding module and then remotely transmitted to a processor via a data feedback module. Upon receiving the data, the processor uses a data classification module and a data comparison module to classify and compare the received data, perform fault analysis, and identify abnormal data.
[0003] In the existing technology described above, equipment movement mainly relies on the friction between pulleys and the wiring. However, the contact between the pulleys and the low-voltage wiring is point contact. On inclined low-voltage wiring, gravity causes uneven distribution of the normal force between the pulleys and the wiring, resulting in unstable friction. When the inclination angle is large, the pulleys are prone to slipping due to insufficient friction, preventing the equipment from moving at the predetermined speed.
[0004] In view of this, in order to improve the ability of the main body of the low-voltage engineering circuit equipment to move on the line, a low-voltage engineering circuit testing device is proposed. Utility Model Content
[0005] The purpose of this utility model is to provide a main body of a low-voltage engineering line equipment that can move stably and reliably on low-voltage lines, especially inclined lines, and avoid slippage to improve the movement performance of the main body of the equipment.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a low-voltage engineering line testing device, comprising a main body, the main body comprising a sleeve, a frame symmetrically arranged on both sides of the sleeve, a bidirectional cylinder connected between the sleeve and the frame for driving the two frames to move closer or further apart on the side of the sleeve, a acquisition module mounted on the sleeve for acquiring images of the low-voltage line surface, and a moving mechanism mounted on the frame for moving the main body of the device on the low-voltage line;
[0007] The two frames have two recesses embedded in their sides, and two limiting slots for accommodating low-voltage lines are embedded in the top of the two recesses. The bottom of the recesses has a first clamping mechanism for clamping the low-voltage lines within the limiting slots. The moving mechanism includes:
[0008] The first telescopic cylinder is fixedly connected at one end to the frame;
[0009] The mounting plate is fixed to the other end of the first telescopic cylinder;
[0010] The lower clamping plate is fixed to the bottom of the mounting plate;
[0011] An upper clamping plate is vertically and movably disposed on the top of the mounting plate, and a second telescopic cylinder is connected between the upper clamping plate and the top of the mounting plate. When the second telescopic cylinder extends, it can drive the upper clamping plate closer to the lower clamping plate and form a second clamping mechanism capable of clamping the low-voltage circuit. The first clamping mechanism and the second clamping mechanism alternately clamp the low-voltage circuit when they are working. When the first clamping mechanism clamps the low-voltage circuit, the first telescopic cylinder retracts, which can drive the second clamping mechanism closer to the device body. When the second clamping mechanism clamps the low-voltage circuit, the first telescopic cylinder extends, which can drive the device body away from the second clamping mechanism.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: Compared with the prior art weak current engineering line detection equipment that relies on pulleys to contact the line and is prone to slippage due to uneven friction on inclined lines, affecting movement, this utility model uses a first clamping mechanism and a second clamping mechanism composed of upper and lower clamping plates to alternately and firmly clamp the weak current line, providing a stable support point for the equipment. At the same time, the extension and retraction of the first telescopic cylinder drives the main body of the equipment to move, ensuring that the equipment can move stably on inclined weak current lines and avoid slippage, which greatly improves the reliability of the equipment in complex line environments.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-5 This utility model discloses a low-voltage engineering line detection device. Specifically, it is a device capable of stable movement on a low-voltage line a. It includes a sleeve 10, a frame 20 symmetrically arranged on both sides of the sleeve 10, a bidirectional cylinder 30 connected between the sleeve 10 and the frame 20 for driving the two frames 20 to move closer or further away from each other on the side of the sleeve 10, a data acquisition module 40 installed on the sleeve 10 for acquiring surface images of the low-voltage line a, and a moving mechanism 60 installed on the frame 20 for moving the main body of the device 100 on the low-voltage line a. The above is the prior art. The principle can be referred to in CN116256598U, which discloses a low-voltage engineering line monitoring system and method. It will not be described in detail here.
[0020] In this embodiment, two grooves 21 are embedded in the sides of the two racks 20. Two limiting slots 22 capable of accommodating the low-voltage lines a are embedded in the top of the two grooves 21, and a first clamping mechanism 50 for clamping the low-voltage lines a in the limiting slots 22 is provided at the bottom of the grooves 21. With the above structure, the main body of the equipment 100 can be hung on two adjacent low-voltage lines a through the two limiting slots 22. When connecting the main body of the equipment and the low-voltage lines a, the overall length of the equipment can be adjusted according to the distance between the two low-voltage lines a. Then, the two low-voltage lines a are respectively inserted into the grooves 21 on both sides of the equipment. Releasing the main body of the equipment allows the main body to be suspended on the two adjacent low-voltage lines a through the limiting slots 22 on both sides. The first clamping mechanism 50 clamps the low-voltage lines a, thus limiting the movement of the main body of the equipment.
[0021] To achieve stable movement of the equipment on the low-voltage line a, in this embodiment, the moving mechanism 60 includes a first telescopic cylinder 61 with one end fixedly connected to the frame 20, a mounting plate 62 fixed to the other end of the first telescopic cylinder 61, a lower clamping plate 65 fixed to the bottom of the mounting plate 62, an upper clamping plate 64 vertically and movably disposed on the top of the mounting plate 62, and a second telescopic cylinder 63 connected between the upper clamping plate 64 and the top of the mounting plate 62. When the second telescopic cylinder 63 extends, it can drive the upper clamping plate 64 to approach the lower clamping plate 65 and form a second clamping mechanism capable of clamping the low-voltage line a.
[0022] When the first clamping mechanism 50 and the second clamping mechanism are working, they alternately clamp the weak current line a. When the first clamping mechanism 50 clamps the weak current line a, the first telescopic cylinder 61 retracts, which can drive the second clamping mechanism to move closer to the main body of the equipment. When the second clamping mechanism clamps the weak current line a, the first telescopic cylinder 61 extends, which can drive the main body of the equipment to move away from the second clamping mechanism.
[0023] With the above structure, when the main body of the equipment needs to be moved, the second telescopic cylinder 63 first extends to move the upper clamping plate 64 downward and clamp the low-voltage line a. Then, the first telescopic cylinder 61 extends to push the frame 20 along the length of the low-voltage line a. After the frame 20 is moved by the first telescopic cylinder 61, the first clamping mechanism 50 clamps the low-voltage line a, fixing the frame 20 to the low-voltage line a. The second telescopic cylinder 63 is released, and the first telescopic cylinder 61 is shortened to move the second clamping mechanism, composed of the upper clamping plate 64 and the lower clamping plate 65, to the rear of the main body of the equipment. Then, the upper clamping plate 64 and the lower clamping plate 65 clamp the low-voltage line a again. The first clamping mechanism 50 is released, and the first telescopic cylinder 61 extends to push the frame 20 again. By repeating the above actions, the main body of the equipment can be moved stably on the low-voltage line a. Compared with the prior art, this method, using the first clamping mechanism 50 and the upper clamping plate 64 and the lower clamping plate 65, achieves a more stable movement. The second clamping mechanism can alternately and firmly clamp the low-voltage line a, providing a stable and reliable support point for the equipment. The telescopic movement of the first telescopic cylinder 61 can precisely control the movement step of the equipment, ensuring that the equipment maintains a stable movement posture on the inclined low-voltage line a, without slippage, greatly improving the reliability of the equipment in complex line environments.
[0024] In some embodiments, the first clamping mechanism 50 includes a third telescopic cylinder 52 fixed to the bottom of the groove 21. The telescopic end of the third telescopic cylinder 52 is fixed with a clamping plate 51. In use, the clamping plate 51 moves upward by extending the third telescopic cylinder 52. When the clamping plate 51 moves upward, it clamps the weak current line a in the limiting groove 22. In this way, when the first telescopic cylinder 61 retracts, the main body of the equipment will not move on the weak current line a.
[0025] like Figure 4 As shown, a rubber pad 23 is fixed at the bottom of the limiting groove 22. The rubber pad 23 increases the friction between the device and the weak current line a, so that the main body of the device can be better positioned on the weak current line a.
[0026] In some embodiments, the opposing surfaces of the upper clamping plate 64 and the lower clamping plate 65 are both arc structures, and rubber blocks are fixed to the opposing surfaces of the upper clamping plate 64 and the lower clamping plate 65.
[0027] Preferred, such as Figure 1and Figure 3 As shown, one end of the first telescopic cylinder 61 is embedded and fixed inside the frame 20. Specifically, the cylinder body of the first telescopic cylinder 61 is fixed inside the frame 20. When not in use, the telescopic end of the first telescopic cylinder 61 is shortened, which can reduce the space occupied.
[0028] This utility model relates to a low-voltage engineering line testing device, which can overcome the shortcomings of existing technology where the pulleys are prone to slippage on inclined lines due to point contact. Through the cooperation of two sets of clamping mechanisms and telescopic cylinders, the device can move stably and reliably on low-voltage lines, especially inclined lines.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
