Description

Technical Field

[0001] The utility model relates to the technical field of electric power maintenance, in particular to an insulator pollution collection device. Background Art

[0002] In the power system, insulators are one of the key power equipment. Their main function is to suspend the conductors and ensure that the conductors are insulated from the towers and the ground. However, due to long-term exposure to the natural environment, a large amount of dirty substances such as dust, salt, bird droppings, etc. tend to accumulate on the surface of insulators. These dirty substances not only affect the appearance of the insulators, but more importantly, they will change the electrical properties of the insulators, reduce their insulation strength, and may even cause flashover accidents, seriously threatening the safe operation of the power system.

[0003] The Chinese utility model patent with publication number CN215573827U discloses an insulator dirt collection device. In this technology, a small pump is used to pump the distilled water in the device to the cleaning brush, and the dirt on the surface of the insulator piece is circulated and cleaned, so that the dirt collection work of the insulator piece can be completed without disassembling the insulator piece. However, when using the cleaning brush to clean the dirt on the surface of the insulator piece, the tray is mainly fixed to the insulator by a clamp composed of two semi-ring bodies to collect the dirt cleaned by the cleaning brush, but the fixing and disassembly of the two semi-ring bodies is mainly achieved by the operation and maintenance personnel manually turning the locking bolts to achieve the fastening with the insulator. Since the insulator is generally set at high altitude, this method of manually disassembling and assembling the locking bolts not only increases the difficulty of operation, but also greatly reduces the work efficiency.

[0004] Therefore, an insulator pollution collection device is needed to solve the above problems. Utility Model Content

This method can ensure the comprehensiveness and directness of dirt collection.

[0013] Preferably, in order to facilitate the installation of the driving assembly, a receiving groove is formed at a position corresponding to the driving assembly in the concave frame; the receiving groove provides a reserved space for the driving assembly.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0031] The present utility model provides an insulator pollution collection device, as Figures 1 - 3As shown in the figure, the pollution collection device includes a hand-held sampling mechanism 2 arranged on the insulator 1 for sampling the dirt on the umbrella skirt surface of the insulator 1, a first semi-circular ring 3 and a second semi-circular ring 4 symmetrically arranged on the column body of the insulator 1 and connected to the hand-held sampling mechanism 2 for fixing the hand-held sampling mechanism 2 and the column body of the insulator 1, and a collection groove 6 arranged on the hand-held sampling mechanism 2 at a position corresponding to the lower side of the second semi-circular ring 4 for receiving dirt; the pollution collection device further includes an adjustment mechanism 5 arranged on the hand-held sampling mechanism 2 for adjusting and locking the distance between the first semi-circular ring 3 and the second semi-circular ring 4; the adjustment mechanism 5 includes a mounting plate 51 arranged on one side of the column body of the insulator 1 and at a position below the first semi-circular ring 3 and the second semi-circular ring 4, a first connecting block 52 that moves horizontally on the mounting plate 51 and is fixedly connected to the side of the first semi-circular ring 3 close to the mounting plate 51, a second connecting block 53 fixedly connected to the mounting plate 51 and connected to the side of the second semi-circular ring 4 close to the mounting plate 51, a lead screw 54 rotatably connected to the mounting plate 51 and the second connecting block 53 and screwed to the first connecting block 52, and a driving member 55 fixedly installed on one side of the mounting plate 51 for driving the lead screw 54 to rotate.

[0032] It should be noted that the driving member 55 is a servo motor or a stepper motor.

[0033] When in use, the operation and maintenance personnel first hold the hand-held sampling mechanism 2, place the hand-held sampling mechanism 2 at the accurate position of the umbrella skirt of the insulator 1 to be sampled, and at the same time, put the second semi-arc ring 4 close to one side of the column of the insulator 1, and then start the driving member 55 to drive the screw rod 54 to rotate. Since the screw rod 54 is screwed to the first connecting block 52 connected to the first semi-arc ring 3, and the first connecting block 52 slides horizontally on the mounting plate 51, therefore, as the screw rod 54 rotates, the first connecting block 52 can drive the first semi-arc ring 3 to move in the direction close to the second semi-arc ring 4. When the first semi-arc ring 3 contacts the other side of the column of the insulator 1, as the screw rod 54 continues to drive, the first semi-arc ring 3 and the second semi-arc ring 4 can firmly fix the column of the insulator 1 to the fixed column, and then, the driving of the driving member 55 is suspended. At this time, through the first semi By clamping the arc ring 3 and the second semi-arc ring 4, the entire hand-held sampling mechanism 2 can be fixed at the position of the shed of the insulator 1. At this time, the operation and maintenance personnel can start the hand-held sampling mechanism 2 again to frictionally sample the dirt on the surface of the shed to be sampled. However, in the process of using the hand-held sampling mechanism 2 for friction sampling, the fallen dirt can be automatically collected by the collection groove 6 for subsequent use. After the sampling is completed, the hand-held sampling mechanism 2 can be paused, and the driving member 55 can be started again to drive the first semi-arc ring 3 to move away from the second semi-arc ring 4, so that the clamping and fixing of the first semi-arc ring 3 and the second semi-arc ring 4 on the column of the insulator 1 can be released. Finally, the operation and maintenance personnel can hold the hand-held sampling mechanism 2, move the hand-held sampling mechanism 2 away from the insulator 1, and then extract the collected dirt from the hand-held sampling mechanism 2 for detection.

[0034] Among them, in order to further ensure the stability of the movement of the first connecting block 52, a sliding groove 511 is opened at the position below the mounting plate 51 corresponding to the first connecting block 52, and the bottom of the first connecting block 52 is slidably connected in the sliding groove 511; the design of the sliding groove 511 provides a fixed moving trajectory for the first connecting block 52, limits the direction and range of its lateral movement, thereby significantly enhancing the stability of the first connecting block 52 during the movement, and further ensuring the overall stability of the adjustment mechanism 5.

[0035] Specifically, the handheld sampling mechanism 2 includes a concave frame 21 disposed on one side of the insulator 1 umbrella skirt and fixedly connected to the second semi-circular ring 4 and the collection groove 6 at both ends, a sampling roller 22 symmetrically rotatably disposed between the second semi-circular ring 4 and the collection groove 6 and in contact with the surface of the insulator 1 umbrella skirt, a driving assembly 23 disposed on the concave frame 21 for driving the two sampling rollers 22 to rotate, and a handheld rod 24 fixedly installed on the side of the concave frame 21 away from the insulator 1 umbrella skirt; the operation and maintenance personnel can hold the handheld rod 24 and place the two sampling rollers 22 on the upper and lower surfaces of the insulator 1 umbrella skirt to be sampled. After the two sampling rollers 22 are in the accurate position, the distance between the first semi-circular ring 3 and the second semi-circular ring 4 is adjusted by starting the adjustment mechanism 5, and the handheld sampling mechanism 2 is fixed on the insulator 1 by using the first semi-circular ring 3 and the second semi-circular ring 4. Then, the driving assembly 23 can be started to drive the two sampling rollers 22 to rotate. Subsequently, the two rotating sampling rollers 22 can directly contact and rub the upper and lower surfaces of the umbrella skirt to be sampled, so that the sampling and collection of dirt can be easily completed.

[0036] In addition, in order to facilitate the installation of the driving assembly 23, a receiving groove 211 is provided at the position corresponding to the driving assembly 23 in the concave frame 21; the receiving groove 211 provides a reserved space for the driving assembly 23. This design greatly simplifies the installation process and improves work efficiency.

[0037] Furthermore, the driving assembly 23 includes transmission wheels 232 symmetrically and rotatably connected in the receiving groove 211, a transmission belt 233 disposed on the two transmission wheels 232, a driving motor 234 fixedly installed on the side of the concave frame 21 corresponding to the handheld rod 24 for driving one of the transmission wheels 232 to rotate, and a connecting shaft 231 fixedly connected to the two transmission wheels 232 and horizontally penetrating the receiving groove 211 and the concave frame 21. One ends of the two connecting shafts 231 away from the two transmission wheels 232 are respectively screwed to one ends of the two sampling rollers 22 away from the insulator 1 umbrella skirt. The two transmission wheels 232 are connected and transmit power through the transmission belt 233; when it is necessary to drive the two sampling rollers 22 to rotate for sampling, the driving motor 234 can be started to drive the transmission wheel 232 connected thereto to rotate. Since the two transmission wheels 232 are connected and transmit power through the transmission belt 233, and the two transmission wheels 232 are connected to the two sampling rollers 22 through the connecting shaft 231, when one of the transmission wheels 232 rotates, the two sampling rollers 22 can rotate synchronously. Thus, the two sampling rollers 22 can uniformly sample the upper and lower surfaces of the umbrella skirt to be sampled. After sampling is completed, since the sampling roller 22 is screwed to the connecting shaft 231, the sampling roller 22 can be removed from the corresponding connecting shaft 231 by rotating the sampling roller 22, so that the operation and maintenance personnel can collect the dirt remaining on the sampling roller 22 after friction for detection.

[0038] Furthermore, a waste discharge port 61 is fixedly arranged at the bottom on one side of the collection tank 6, and a sealing cover is screwed to the end of the waste discharge port 61 away from the interior of the collection tank 6; when it is necessary to discharge the dirt collected in the collection tank 6, the maintenance personnel can rotate the sealing cover to release the connection between the sealing cover and the waste discharge port 61, and then the collected dirt can be discharged from the collection tank 6 for later measurement or treatment. When it is necessary to use the handheld sampling mechanism 2 for sampling, the sealing cover can be screwed tightly at the waste discharge port 61 to seal the waste discharge port 61. Therefore, when using the handheld sampling mechanism 2 for friction sampling, the collection tank 6 can synchronously collect the fallen dirt for later use.

[0039] Even further, the interior of the collection tank 6 has an inclined surface that slopes towards the waste discharge port 61; the design of the inclined surface enables the dirt collected in the collection tank 6 to naturally flow and accumulate towards the waste discharge port 61, thereby improving the efficiency of dirt discharge.

[0040] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
