Description

Technical Field

[0001] The utility model relates to the field of insulator pollution monitoring, and specifically to a device for monitoring the pollution of transmission line insulators. Background Technique

[0002] The field of insulator pollution monitoring mainly focuses on monitoring and evaluating the pollutants accumulated on the surface of insulators in the power grid. These pollutants may include impurities such as dust, salt, oil, and animal feces, which may come from the natural environment (such as dust, saline-alkali, bird droppings, etc.) or industrial emissions (such as soot, waste gas, etc.). These pollutants will affect the insulation performance of insulators and may even cause accidents such as corona discharge and flashover.

[0003] The existing insulator pollution monitoring device includes a monitoring device body. A base fixing mechanism is provided at the bottom of the monitoring device body. The base fixing mechanism includes a connecting member, a fixing component, and a clamping component. The connecting member includes a connecting plate. The fixing component includes a first fixing plate, a second fixing plate, a hinge, a screw rod, and a fixing block. The clamping component includes a rotating shaft, two clamping blocks, and a spring.

[0004] For the above-mentioned insulator pollution monitoring device, with the design of the fixing component, the installation of the monitoring device is simpler. However, its fixing component is composed of two clamping plates and a locking rod, which is suitable for clamping on a square pole frame. However, insulators are generally installed on iron towers, and the most commonly used components of iron towers are angle irons. If the above device is used for installation, the clamping will be unstable due to the triangular shape of the angle iron. For installing on angle irons, the existing method is to use a connecting member with bolts and nuts as a conversion component, but this method will be more troublesome for operators. Generally speaking, the above-mentioned insulator pollution monitoring device is not suitable for installing on a wider range of angle irons, so its application range is small and its practicability is low.

[0005] Therefore, a device for monitoring the pollution of transmission line insulators is provided to solve the above problems. Content of the Utility Model

[0006] (1) Technical Problems to be Solved

[0007] The utility model provides a device for monitoring the pollution of transmission line insulators, aiming to solve the problem of low practicability caused by the fact that the existing insulator pollution monitoring device is not suitable for installation on the angle irons of iron towers as mentioned in the background technique.

[0008] (2) Technical Solutions

[0009] To achieve the above object, the utility model provides the following technical solution: A device for monitoring the pollution of transmission line insulators includes a monitor body, a support base installed at the bottom of the monitor body, and a locking component provided on the support base.

[0010] To facilitate the fixing of the support base on the angle iron, a thickness plate and a width plate arranged side by side are fixedly connected to the bottom of the support base. The locking assembly includes a clamping plate hinged to the bottom end of the thickness plate or the width plate, a movable groove opened on the clamping plate, a pin moving close to or away from the clamping plate in the movable groove, a spring arranged in the movable groove and connected to the pin and the inner wall of the clamping plate at both ends, and a traction rope fixedly connected to one end of the pin close to the spring. The end of the traction rope away from the pin penetrates through the side of the clamping plate close to the angle iron. Locking holes corresponding to the pins are opened at one end of the thickness plate and the width plate close to the clamping plate. By placing the monitor body together with the support base on this angle iron, the thickness plate and the width plate are just stuck on both sides of the angle iron. Then, the clamping plates on the thickness plate and the width plate are turned towards the angle iron in sequence. After the clamping plates are turned by 90 degrees, the pins are aligned with the locking holes on the thickness plate and the width plate. At this time, the pins pop out under the action of the spring and are inserted into the corresponding locking holes, thereby restricting the clamping plates from moving again, and further fixing the support base on the angle iron through the two clamping plates.

[0011] Preferably, to ensure that the thickness plate and the width plate fit and are more stable after clamping the angle iron, the distance between the thickness plate and the width plate and the height of the width plate are both equal to the width of the angle iron, and the height of the thickness plate is equal to the thickness of the angle iron.

[0012] Preferably, to facilitate the adjustment of the position when installing the monitor body, the bottom end of the monitor body has an annular flange, and at least three adjustment grooves are opened on the annular flange and distributed in an annular array.

[0013] Preferably, to ensure that the monitor body is firmly installed and easy to disassemble and assemble, at least three fixing bolts are fixedly connected to the side of the support base close to the monitor body, and gasket nuts in contact with the side of the annular flange away from the support base are screwed on the fixing bolts; by unscrewing the gasket nuts from the fixing bolts, the limit on the annular flange is released, so that the monitor body and the support base can be separated.

[0014] Preferably, to make the clamping plate clamp the angle iron more firmly and prevent loosening, there are at least three groups of the movable groove, the pin, the traction rope and the spring on the clamping plate.

[0015] Preferably, to facilitate the simultaneous pulling of the pins and simplify the unlocking operation, the end of the traction rope has a handle head, and the ends of the traction ropes are fixedly connected to the same handle head.

[0016] Preferably, in order to further improve the stability of the support seat after being installed on the angle iron and prevent it from sliding laterally, a locking bolt with an end contacting the surface of the angle iron is screwed on the side of the width plate away from the angle iron; after the support seat is fastened to the angle iron through the clamping plate, the locking bolt is tightened again so that the end of the locking bolt abuts against the surface of the angle iron, thereby tensing the acting forces between the angle iron, the clamping plate, the thickness plate and the width plate, and thus avoiding shaking.

[0017] (III) Beneficial effects

[0018] For the pollution monitoring device of the transmission line insulator, through the designed locking component, the monitor body together with the support seat can be quickly installed on the angle iron of the iron tower and can be conveniently disassembled, and the unlocking process is simple and fast. Since it can be directly installed on the widely used angle iron, the practicality of this device is higher.

[0019] For the pollution monitoring device of the transmission line insulator, by adding a locking bolt, the acting forces between the angle iron, the clamping plate, the thickness plate and the width plate can be further tightened, thereby avoiding shaking caused by long-term wind blowing at high altitude and improving the stability and reliability of the entire monitoring device.

[0020] For the pollution monitoring device of the transmission line insulator, a detachable design is adopted between the monitor body and the support seat. When the monitor body needs to be replaced or maintained, the two can be conveniently separated, which is convenient for subsequent maintenance work. Description of the drawings

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1

[0031] Please refer to Figures 1 - 5 , the present invention provides a technical solution: a pollution monitoring device for a transmission line insulator, including a monitor body 1 and a support base 2 installed at the bottom of the monitor body 1. The bottom of the support base 2 is fixedly connected with a thickness plate 22 and a width plate 23 arranged in parallel. The ends of the thickness plate 22 and the width plate 23 far from the support base 2 both have a locking assembly 3.

[0032] The locking assembly 3 includes a clamping plate 31 hinged at the bottom end of the thickness plate 22 or the width plate 23, an activity groove 32 opened on the clamping plate 31, a pin 33 moving close to or away from the clamping plate 31 in the activity groove 32, a spring 35 arranged in the activity groove 32 and connected to the pin 33 and the inner wall of the clamping plate 31 at both ends, and a traction rope 34 fixedly connected to the end of the pin 33 close to the spring 35. The end of the traction rope 34 far from the pin 33 penetrates through the side of the clamping plate 31 close to the angle iron. Lock holes 331 corresponding to the pin 33 are opened at one end of the thickness plate 22 and the width plate 23 close to the clamping plate 31.

[0033] The distance between the thickness plate 22 and the width plate 23 and the height of the width plate 23 are both equal to the width of the angle iron, and the height of the thickness plate 22 is equal to the thickness of the angle iron.

[0034] In use, the worker carries the monitoring device near the tower insulator, selects the angle iron, determines the installation position, and then places the monitor body 1 together with the support base 2 on this angle iron, so that the thickness plate 22 and the width plate 23 just clamp on both sides of the angle iron. Then, the clamping plates 31 on the thickness plate 22 and the width plate 23 are flipped towards the angle iron in sequence. After the clamping plate 31 is flipped by 90 degrees, the pin 33 aligns with the locking holes 331 on the thickness plate 22 and the width plate 23. At this time, the pin 33 pops out under the action of the spring 35 and inserts into the corresponding locking hole 331, thereby restricting the clamping plate 31 from moving again. Furthermore, the support base 2 is fixed to the angle iron through the two clamping plates 31. When disassembling, only need to pull the traction rope 34, thus driving the pin 33 to retract into the moving slot 32 of the clamping plate 31 to complete unlocking. Then, under the action of gravity, the clamping plate 31 automatically drops to achieve unlocking. After that, the support base 2 can be removed from the angle iron.

[0035] Specifically, the bottom end of the monitor body 1 has an annular flange 11. At least three adjustment slots 111 distributed in an annular array are opened on the annular flange 11. At least three fixing bolts 21 distributed in an annular array are fixedly connected to the side of the support base 2 close to the monitor body 1. Gasket nuts 211 that contact the side of the annular flange 11 away from the support base 2 are screwed on the fixing bolts 21. When the monitor body 1 needs to be replaced or maintained, the limit on the annular flange 11 is released by unscrewing the gasket nuts 211 from the fixing bolts 21, so that the monitor body 1 and the support base 2 can be separated. When reinstalling, the annular flange 11 of the monitor body 1 is sleeved on the fixing bolts 21 through the adjustment slots 111. With the existence of the adjustment slots 111, the monitor body 1 can be rotated to adjust the position. After determination, tighten the gasket nuts 211 on the fixing bolts 21 again to lock the monitor body 1 on the support base 2.

[0036] Furthermore, there are at least three sets of the moving slot 32, the pin 33, the traction rope 34 and the spring 35 on the clamping plate 31. The end of the traction rope 34 has a head 341, and the ends of the traction ropes 34 are fixedly connected to the same head 341. By increasing the number of pins 33, the limiting force on the clamping plate 31 is improved, making the support base 2 and the angle iron fit more firmly after installation, which helps to prevent detachment. At the same time, using the same head 341 can pull all the traction ropes 34 simultaneously. Therefore, when unlocking the clamping plate 31, all the pins 33 can be driven to retract by pulling the head 341, improving the stability while maintaining simple operation.

[0037] Embodiment 2

[0038] Please refer to Figure 6 , different from Embodiment 1, a locking bolt 4 with an end contacting the surface of the angle iron is screwed on the side of the width plate 23 away from the angle iron.

[0039] After the support base 2 is installed on the angle iron, in order to prevent gaps between the thickness plate 22 and the width plate 23 and the angle iron, which may cause shaking due to long-term wind blowing at high altitudes, after the support base 2 fastens the angle iron through the clamping plate 31, the lock bolt 4 is tightened again so that the end of the lock bolt 4 abuts against the surface of the angle iron, to tighten the acting force between the angle iron, the clamping plate 31, the thickness plate 22 and the width plate 23, thereby avoiding shaking.

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