Description

Technical Field

[0001] The present invention relates to the technical field of power distribution network inspection, and in particular to a power distribution network inspection device and a use method thereof. Background Art

[0002] The power distribution network, also known as the distribution network, is an important component of the power system. It is mainly responsible for efficiently distributing electricity from the transmission network or regional power plants to various end users. The distribution network consists of overhead lines, cables, poles, distribution transformers, disconnectors, reactive power compensators and some ancillary facilities. Its function is to convert high-voltage electricity into low-voltage electricity to meet the electricity needs of different users. Since overhead lines operate in the open air for a long time, they are often affected by the surrounding environment and changes in nature. Therefore, professional personnel are required to regularly patrol and inspect the lines to understand the operation status of the lines and promptly detect line defects so that they can quickly carry out maintenance to ensure the safe operation of the lines.

[0003] The patent authorization announcement number CN109167295A discloses a line patrol auxiliary device, including an auxiliary walking stick body and a spraying mechanism, wherein the bottom of the auxiliary walking stick body is provided with a walking stick base, the outer side of the bottom end of the walking stick base is connected to an anti-sinking plate, the end of the anti-sinking plate away from the walking stick base is connected to a tungsten steel walking stick tip, and the end of the walking stick base away from the tungsten steel walking stick tip is connected to an adjustment inner tube. Although the above patent can send a signal to the power supply station command center to dispatch corresponding maintenance personnel by setting a camera, a signal transmitter and a processing controller, thereby saving maintenance time, there are still some shortcomings in actual use. For example, during the line patrol process, the patrol personnel always move the auxiliary walking stick body by hand, and the laying height of the line is generally higher than the height of a human body, so the patrol personnel need to hold the auxiliary walking stick body while patrolling the line. Holding the auxiliary walking stick body for a long time can easily cause the patrol personnel's arms to be tired, thereby increasing the patrol personnel's work intensity.

[0014] A method for using a power distribution network inspection device, the specific steps of the method are as follows:

[0015] S1. Pull the front plate forward to increase the distance between the front plate and the rear plate, then place the front plate and the rear plate on both sides of the cable and release the front plate. The second spring assists the front plate to move backward and cooperate with the rear plate to clamp the cable.

[0016] S2. Pull the front slide forward to widen the distance between the two adjacent rollers. Then, place the front slide, rear slide, and two adjacent rollers on both sides of the cable. Release the front slide. The third spring assists the front slide in moving backward, shortening the distance between the two adjacent rollers so that the two adjacent rollers can clamp the cable again. Then, start the motor, and the rear roller rotates to cooperate with the front roller, allowing the support frame to move on the cable.

[0017] S3, by starting the second electric slide rail, controlling the second electric slider to slide downward on the second electric slide rail to squeeze the connecting frame, and the connecting frame drives the front clamping plate and the front slide plate to move forward on their own;

[0018] S4. Start the two first electric slide rails and control the first electric slider to slide forward between the two first electric slide rails. The first electric slide rails drive the moving block and the connecting rod to move forward, and the marking block contacts the cable surface to complete the marking.

[0019] S5. Insert the cable through the gap into the support frame to contact the brush bristles, then start the motor, the gear rotates to engage with the gear teeth of the ring gear plate, and the ring gear plate drives the brush bristles to rotate and clean the cable surface;

[0020] S6. By starting the air pump, the external gas is transported into the air storage box. When the ring gear plate rotates, it drives the protrusion to rotate and intermittently squeeze the slide. The slide drives the squeezing rod to move forward and squeeze the valve stem. The valve stem drives the valve to rotate and open the gas pipe for jetting.

[0021] From the above description of the structure of the present invention, it can be seen that the design starting point, concept and advantages of the present invention are: 1. By setting a clamping mechanism and a walking mechanism, the front splint, the front slide, the rear splint, the rear slide and the roller cooperate to double-clamp the cable, so as to limit the hand-held rod to the cable, and then start the motor to rotate the rear roller and cooperate with the front roller to drive the support frame to move on the cable, effectively solving the problem that the inspectors have always been holding the auxiliary cane body to move the inspection route, thereby reducing the work intensity of the inspectors.

[0022] 2. By setting up a pulling mechanism, the second electric slide rail is started, and the second electric slide block is controlled to slide downward, thereby squeezing the connecting frame to drive the front splint and the front slide plate to move forward on their own. The second spring and the third spring are then stretched, thereby eliminating the need to manually pull the front splint and the front slide plate.

[0023] 3. By setting up a cleaning mechanism, turning on the motor to rotate the gear and engage with the gear teeth of the ring gear plate, the ring gear plate drives the brush to rotate to clean the cable surface, thereby improving the cleanliness of the cable surface, allowing the detector to better detect the cable in the future, and also allowing the marking mechanism to better mark the cable surface in the future.

[0024] 4. By setting up the jet mechanism, turn on the air pump to deliver external air into the air pipe. When the ring gear plate rotates, it drives the convex block to rotate intermittently to squeeze the slide forward, and then the slide drives the extrusion rod to move forward to squeeze the valve stem to rotate, and then the valve stem drives the valve to rotate 90 degrees to open the air pipe. The gas in the air storage tank is ejected from the air pipe to the surface of the cable, and then the dust and other impurities on the surface of the cable are blown off, so as to achieve the purpose of pre-cleaning the cable surface and ensure the cleaning effect of the cable.

[0025] 5. By setting up a marking mechanism, when a cable is detected to be damaged or abnormal, the detector transmits a signal to the controller, and the controller immediately starts the two first electric slide rails, controls the first electric slide to slide forward to the limit, and then drives the moving block and the connecting rod to move forward, so that the marking block contacts the cable surface for marking, thereby achieving the purpose of automatic marking, which is convenient for maintenance personnel to quickly find the location of cable damage or abnormality for repair later.

[0050] See Figure 10 、 Figure 11 and Figure 16 As shown, the patrol device also includes a cleaning mechanism, which includes a support frame 29, a ring gear plate 30, bristles 32, a motor 34 and a gear 33. The front side of the support frame 3 is connected to the support frame 29 by welding, and the support frame 29 is internally connected to the ring gear plate 30 for rotation.

[0051] See Figure 11-14 As shown, the patrol device also includes an injection mechanism, which includes a connecting plate 2901, a protrusion 31, an air storage box 35, an air pump 36, an air pipe 37, a slide 38, an extrusion rod 3801, a fourth spring 39, a valve stem 40, a valve 42 and a torsion spring 41. The rear side of the support frame 29 is connected to the connecting plate 2901 by welding, and the right edge of the ring gear plate 30 is connected to the symmetrically distributed protrusions 31 by welding. The rear side of the connecting plate 2901 is connected to the air storage box 35 by welding, and the rear side of the upper part of the air storage box 35 is connected to the air pump 36 by bolts.

[0052] See Figure 1 As shown, a controller 47 is also included. The controller 47 is connected to the outside of the lower end of the hand-held rod 1 by bolts.

[0053] When the front splint 18, the rear splint 15, the front slide 24 and the rear slide 21 are placed on both sides of the cable respectively, the cable simultaneously passes through the support frame 29 from the gap and contacts the brush 32. Before inspecting the cable, the inspector turns on the motor 34 and the air pump 36. The output shaft of the motor 34 rotates to drive the gear 33 to rotate and engage with the gear teeth of the ring gear plate 30, and then the ring gear plate 30 drives the brush 32 to rotate and clean the cable surface, thereby improving the cleanliness of the cable surface, making it easier for the detector to detect the cable later, and also making it easier for the marking mechanism to mark the cable surface later. At the same time, the air pump 36 runs to deliver external air to the air pipe 37. When the gear ring plate 30 rotates, it drives the protrusion 31 to rotate intermittently to squeeze the slide 38 forward, and the fourth spring 39 is compressed, so that the slide 38 drives the squeezing rod 3801 to move forward to squeeze the valve stem 40 to rotate, and the torsion spring 41 is deformed accordingly, so that the valve stem 40 drives the valve 42 to rotate 90 degrees to open the gas pipe 37, and the gas in the gas storage box 35 is ejected from the gas pipe 37 to the surface of the cable, thereby blowing off the dust and other impurities on the surface of the cable, so as to achieve the purpose of pre-cleaning the cable surface and ensure the cleaning effect of the cable. When the protrusion 31 rotates intermittently to stop squeezing the slide 38, the fourth spring 39 returns to its original state. , and then the slide 38 drives the extrusion rod 3801 to move backward and disengage from the valve stem 40, and the torsion spring 41 returns to its original state, and then the valve stem 40 drives the valve 42 to reverse 90 degrees to close the gas pipe 37, thereby achieving the effect of intermittent jetting, ensuring the flow strength of the gas every time the gas pipe 37 jets. When the cable is detected to be damaged or abnormal, the detector transmits a signal to the controller 47, and the controller 47 immediately starts the two first electric slide rails 8, controls the first electric slider 9 to slide forward and backward to the limit in turn, and when the first electric slider 9 slides forward, it drives the moving block 10 and the connecting rod 11 to move forward. When marking, the marking block 12 is squeezed by the cable and moves backward, thereby driving the connecting rod 11 to move backward. The first spring 13 is compressed and applies pressure to the connecting rod 11, thereby making the marking block 12 close to the cable surface to achieve a good marking effect. When the first electric slider 9 slides backward, it drives the moving block 10 and the connecting rod 11 to move backward, thereby causing the marking block 12 to break contact with the cable surface, and the first spring 13 then returns to its original state.

[0054] A method for using a power distribution network inspection device, the specific steps of the method are as follows:

[0055] S1. Pull the front clamping plate 18 forward to increase the distance between the front clamping plate 18 and the rear clamping plate 15. Then, place the front clamping plate 18 and the rear clamping plate 15 on both sides of the cable and release the front clamping plate 18.
