Description

TECHNICAL FIELD

[0001] The application relates to the technical field of power line fault detection, and particularly relates to a power line fault detection device. BACKGROUND

[0002] A power line fault refers to the phenomenon that the components of a power transmission line are damaged due to electrical or mechanical performance, thereby completely or partially losing the specified functions and causing abnormal operation states. The core feature is that the line elements cannot maintain normal power transmission capacity, which may cause abnormal current, voltage fluctuation, equipment damage and even power system interruption. The power line fault detection device is a device for detecting power line faults, which is mainly used for monitoring the operation state of the power system, discovering faults in time and diagnosing and processing the faults.

[0003] According to the announcement No. CN113848514B, a line fault detection device comprises a shell, a fault detection device, a heat dissipation device and an air flow discharge device. The shell has an inner cavity. A support plate is arranged in the inner cavity, thereby dividing the inner cavity into a detection cavity and a heat dissipation cavity which are in communication with each other. An air inlet is arranged on the heat dissipation cavity. The fault detection device is installed on the support plate and located in the detection cavity, and is configured to detect the fault of a medium-low voltage distribution network line. The heat dissipation device comprises an air inlet driving assembly arranged in the heat dissipation cavity, which can introduce external air into the heat dissipation cavity through the air inlet and blow the air into the detection cavity. The air flow discharge device is fixedly connected to the shell. The air flow discharge device can discharge the air in the detection cavity. The line fault detection device can solve the problems that the existing water circulation cooling and heat dissipation have poor heat dissipation effect in actual use, are inconvenient for workers to maintain, and cannot effectively ensure the continuous and normal work of the broken line detector in a high-altitude environment.

The detection device further comprises a detection vehicle. The telescopic rod and a positioning rod used for controlling the rotation angle of the telescopic rod are hingedly connected to the detection vehicle. The positioning rod and the telescopic rod are oppositely arranged, thereby achieving the beneficial effects of saving labor and stabilizing the detection cable.

[0005] However, in the use process of the above-mentioned patent, the power line fault detection device can usually only detect the power line on the ground, and it is difficult to detect the underwater power line, so that the worker needs to put the existing line fault detection device aside and prepare a special underwater detection device to detect the underwater power transmission line, thereby limiting the use limitation of the line fault detection device and being inconvenient, thereby affecting the use of the line fault detection device.

The transmission plate 604 and the detection equipment body 1 are slidably connected. The floating plate 607 is distributed at equal angles. The bottom end of the detection equipment body 1 is provided with a movable hole corresponding to the mounting seat 506.

[0022] In specific implementation, referring to Figures 1-6 , in the process of detecting the power line by the fault detection device, when the power line on the ground needs to be detected, first start the electric push rod 502 at the top of the support seat 501. Because the output end of the electric push rod 502 is connected with the base 503, the extension of the electric push rod 502 will drive the base 503 to move together. In this process, the base 503 is guided to move stably through the slide rail 504.

[0023] Referring to Figures 1-3 , because the base 503 is connected with the photographing camera 2, the movement of the base 503 will drive the photographing camera 2 to move together, until the photographing camera 2 moves out of the detection equipment body 1 from the guide outlet 7 to detect the power line on the ground by photographing.

[0024] Referring to Figure 3 , Figure 7 and Figure 9 , when the underwater power transmission line needs to be detected, start the electric push rod 502 to retract to drive the base 503 to move downward, until the base 503 drives the photographing camera 2 to be stored in the detection equipment body 1 for protection.

[0025] Then the continuous downward movement of the base 503 will make the downward pressure column 505 continue to move downward, until the downward pressure column 505 moves downward and contacts the mounting seat 506 to generate a pushing force, so that the mounting seat 506 drives the underwater monitoring camera 507 to move downward.

[0026] Referring to Figure 7 and Figure 9 , at this time, the limiting seat 508 will slide along the fixed column 509, thereby guiding the mounting seat 506 to move stably. The downward movement of the limiting seat 508 will extrude the No. 1 spring 510 to cause it to deform, and then the No. 1 spring 510 will be reset to assist the upward movement of the underwater monitoring camera 507 to return to the original position.

[0027] Until the underwater monitoring camera 507 moves out of the protection cylinder 511, and at this time is located on the water surface, and then through the downward movement of the underwater monitoring camera 507 to detect the underwater power transmission line, and then through the monitoring mechanism 5 to make the power line fault detection equipment, can detect the ground and underwater power transmission line, without the need to replace the special underwater detection equipment, can detect the underwater power transmission line, improve the flexibility and versatility of the power line fault detection equipment, so as to quickly adapt to complex environment and improve the detection efficiency.

[0028] Referring to Figure 3 , Figure 4 , Figure 6 With Figure 8 , the base 503 is lowered to make the underwater monitoring camera 507 move downward for underwater detection, and at this time the detection equipment main body 1 has been located on the water surface, and then the buoy 608 provides buoyancy.

[0029] Then the base 503 is lowered to drive the rotating plate 601 to rotate, and at this time the rotating plate 601 generates a thrust force with the sliding seat 602, so that the sliding seat 602 moves away from the lower pressing column 505 along the fixed strip 603, and the sliding seat 602 is guided by the fixed strip 603 during the movement.

[0030] Referring to Figure 10 , the sliding seat 602 is connected with the support plate 605 through the transmission plate 604, so that the sliding seat 602 moves to drive the transmission plate 604 to move, and the transmission plate 604 moves to drive the support plate 605 to move, and because the support plate 605 is connected with the second spring 606 and the floating plate 607, the support plate 605 moves to drive the floating plate 607 to move, and during this process, the second spring 606 will be deformed, and then the second spring 606 is reset to assist the floating plate 607 to return to the original position.

[0031] Referring to Figure 8 With Figure 10 , when the monitoring mechanism 5 detects the underwater power transmission line, the floating force mechanism 6 works to make the floating plate 607 move away from each other, at this time the water volume of the detection equipment main body 1 is increased, so that the equipment buoyancy is increased, and the increased buoyancy can make the equipment float more stably on the water surface, reduce the risk of inclination, and the increased buoyancy can balance the center of gravity deviation caused by the downward movement of the underwater monitoring camera 507.

[0032] Referring to Figures 1-3 , Figure 11When the base 503 moves downward to drive the photographing camera 2 to be stored in the detection equipment main body 1 for protection, the fixed pin 8 and the cover plate 9 are rotationally connected, at this time, the cover plate 9 is manually pushed to rotate around the fixed pin 8 until the cover plate 9 is moved above the guide outlet 7 to cover it, then the threaded pin 10 is downwardly rotated to be connected with the detection equipment main body 1, and then the cover plate 9 is limited to prevent it from being randomly rotated, so that the guide outlet 7 is covered by the cover plate 9 to prevent the guide outlet 7 from being exposed to cause sundries to enter the detection equipment main body 1.

[0033] In summary, when the power line fault detection equipment is used, the detection equipment main body 1 is first moved to a specified position by the universal wheel 3, then the power line is checked by the photographing camera 2, and the image can be sent to a remote terminal for detection by the signal transmitter, and the fault detection equipment can be manually moved by pushing the handrail 4 during movement, which is the prior art and will not be described in detail. The power line fault detection equipment can detect the ground and underwater power transmission lines by the monitoring mechanism 5, thereby improving flexibility and versatility, so that the power line fault detection equipment can quickly adapt to complex environments to improve detection efficiency. When the monitoring mechanism 5 detects the underwater power transmission line, the buoyancy mechanism 6 works together to increase the buoyancy of the equipment, thereby making the equipment more stably float on the water surface, reducing the risk of tilting. The contents not described in detail in the description belong to the prior art known to those skilled in the art.

[0034] Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacements for part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
