Description

Technical Field

[0001] This utility model belongs to the field of surge arrester technology, specifically relating to a waterproof and dustproof outdoor surge arrester. Background Technology

[0002] A surge arrester is an important device used to protect electrical equipment from damage caused by lightning overvoltage and operational overvoltage. It discharges overvoltage by providing a low-impedance path, thereby protecting the equipment connected to it from damage. Surge arresters are widely used in power systems, communication systems, and other facilities that require lightning protection.

[0003] Existing outdoor surge arresters consist of an external cylindrical insulator and an internal resistive element. Outdoor surge arresters are directly exposed to the outside, and rainwater can easily enter the interior of the insulator through gaps, causing internal dampness and a decrease in resistance performance. In addition, dust accumulates on the cylindrical insulator, resulting in abnormal discharge and surface flashover, which reduces the insulation and safety of the surge arrester. Utility Model Content

[0004] The purpose of this utility model is to provide a waterproof and dustproof outdoor surge arrester with a simple structure and reasonable design in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A waterproof and dustproof outdoor surge arrester includes an insulating center column, on which several insulating discs are uniformly fixedly installed. A top screw is fixedly installed on the top of the insulating center column, and a protective mechanism is provided on the top screw. A bottom screw is fixedly installed at the bottom of the insulating center column, and an angle adjustment mechanism is provided at the bottom of the bottom screw. A fixing nut is fixedly installed on the top of the bottom screw.

[0007] Preferably, the angle adjustment mechanism includes a connecting plate fixedly installed at the bottom of the bottom screw, an arc-shaped plate fixedly installed at the bottom of the connecting plate, a plurality of insertion holes evenly provided on the arc-shaped plate, a hinge seat rotatably installed on the connecting plate, and a fixing plate fixedly installed at the bottom of the hinge seat.

[0008] Preferably, an installation sleeve is fixedly installed on one side of the hinge seat, and a plug rod is movably inserted through the inside of the installation sleeve. One end of the plug rod is movably inserted into the plug hole, and a handle is fixedly installed on the other end of the plug rod. A baffle is fixedly sleeved on one end of the plug rod, and a spring is sleeved on the outside of the plug rod. The spring is located between the baffle and the inner wall of the installation sleeve.

[0009] Preferably, an anti-slip pad is fixedly installed at the bottom of the fixing plate, and bolts are slidably installed through both sides of the top of the fixing plate.

[0010] Preferably, the protective mechanism includes a support ring threaded onto the top of the top screw, a second limiting groove on the top of the support ring, a plurality of first ball bearings evenly rotatably mounted on the outer periphery of the top of the support ring, a protective cover rotatably sleeved onto the top of the top screw, a limiting sleeve fixedly mounted at the center of the protective cover, the bottom of the limiting sleeve being slidably connected inside the second limiting groove, and the top of the first ball bearings being rotatably connected to the bottom of the protective cover.

[0011] Preferably, the top screw is threadedly connected to a crimp nut, and several No. 2 balls are evenly and rotatably installed on the bottom periphery of the crimp nut. A No. 1 limiting groove is opened at the bottom of the crimp nut, and the top of the limiting sleeve is slidably connected to the bottom of the No. 1 limiting groove. The bottom of the No. 2 balls is rotatably connected to the top of the protective cover. Several fixing rods are evenly and fixedly connected to the outer circumference of the protective cover, and a fan blade is fixedly installed at the end of the fixing rod away from the protective cover.

[0012] The beneficial effects of this utility model are as follows: By setting up a protective mechanism, this utility model achieves protection for outdoor surge arresters, reduces the probability of dust and rainwater falling onto the insulating disc, reduces the problem of dust and rainwater entering the interior of the insulator, causing internal dampness and decreased resistance performance, and extends the service life of the equipment.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example

[0022] Please see Figure 1 and Figure 2 A waterproof and dustproof outdoor surge arrester includes an insulating center column 1, several insulating discs 2 uniformly fixedly installed on the outside of the insulating center column 1, a top screw 7 fixedly installed on the top of the insulating center column 1, a protective mechanism 8 provided on the top screw 7, a bottom screw 5 fixedly installed at the bottom of the insulating center column 1, an angle adjustment mechanism 4 provided at the bottom of the bottom screw 5, and a fixing nut 9 fixedly installed on the top of the bottom screw 5.

[0023] In use, the angle adjustment mechanism 4 is used to adjust the installation angle of the equipment, which is convenient to adjust the installation angle of the equipment according to the installation scenario and actual use needs. The protective mechanism 8 is used to protect the insulating disc 2 and the insulating center column 1, so as to prevent rainwater and dust from entering the interior of the insulating center column 1 and causing internal moisture and decreased resistance performance, thus extending the service life of the equipment.

[0024] Please see Figure 2 , Figure 3 and Figure 4The angle adjustment mechanism 4 includes a connecting plate 43 fixedly installed at the bottom of the bottom screw 5. An arc-shaped plate 41 is fixedly installed at the bottom of the connecting plate 43. Several insertion holes 42 are evenly opened on the arc-shaped plate 41. A hinge seat 45 is rotatably installed on the connecting plate 43. A fixing plate 3 is fixedly installed at the bottom of the hinge seat 45. An installation sleeve 44 is fixedly installed on one side of the hinge seat 45. An insertion rod 47 is movably inserted through the inside of the installation sleeve 44. One end of the insertion rod 47 is movably inserted into the insertion hole 42. A handle is fixedly installed at the other end of the insertion rod 47. A baffle 46 is fixedly sleeved on one end of the insertion rod 47. A spring 48 is sleeved on the outside of the insertion rod 47. The spring 48 is located between the baffle 46 and the inner wall of the installation sleeve 44. An anti-slip pad 6 is fixedly installed at the bottom of the fixing plate 3. Bolts 10 are slidably installed through the top two sides of the fixing plate 3.

[0025] In use, firstly, use bolts 10 to fix the fixing plate 3 to the designated position. The anti-slip pad 6 is used to enhance the friction between the fixing plate 3 and the installation position, improving the installation stability. After the fixing plate 3 is installed, pull the plug rod 47 to move the baffle 46 away from the arc plate 41 and compress the spring 48 simultaneously. Then, pull the plug rod 47 out of the plug hole 42. At this time, rotate the connecting plate 43 around the hinge position between the hinge seat 45 and the connecting plate 43, which simultaneously drives the arc plate 41 to rotate. At the same time, it drives the bottom screw 5 and the insulating center column 1 on it to rotate, and simultaneously drives the insulating disc 2 to rotate, realizing the angle adjustment of the outdoor surge arrester. After adjusting to the appropriate position, release the plug rod 47. Under the restoring force of the spring 48, the baffle 46 and the plug rod 47 on it move towards the arc plate 41, so that the plug rod 47 is inserted into the plug hole 42, realizing the installation angle adjustment of the equipment.

[0026] Please see Figure 2 , Figure 5 and Figure 6 The protective mechanism 8 includes a support ring 86 threaded onto the top of the top screw 7. The top of the support ring 86 has a second limiting groove 88. Several first-order balls are evenly rotatably mounted on the outer periphery of the top of the support ring 86. A protective cover 83 is rotatably sleeved on the top of the top screw 7. A limiting sleeve 85 is fixedly mounted in the center of the protective cover 83. The bottom of the limiting sleeve 85 is slidably connected inside the second limiting groove 88. The top of the first-order balls is rotatably connected to the bottom of the protective cover 83. A crimp nut 81 is threaded onto the top screw 7. Several second-order balls are evenly rotatably mounted on the outer periphery of the bottom of the crimp nut 81. A first limiting groove 87 is opened at the bottom of the crimp nut 81. The top of the limiting sleeve 85 is slidably connected to the bottom of the first limiting groove 87. The bottom of the second-order balls is rotatably connected to the top of the protective cover 83. Several fixing rods 82 are evenly fixedly connected to the outer circumference of the protective cover 83. A fan blade 84 is fixedly mounted on the end of the fixing rod 82 away from the protective cover 83.

[0027] In use, first, the support ring 86 is threaded onto the top screw 7. Then, the protective cover 83 is fitted onto the top screw 7, ensuring that the bottom of the limiting sleeve 85 on the protective cover 83 is slidably installed inside the second limiting groove 88. Next, the crimp nut 81 is threaded onto the top screw 7 and crimped to the top of the protective cover 83, while ensuring that the top of the limiting sleeve 85 is slidably connected to the bottom of the first limiting groove 87. When the wind blows, the fan blade 84 is driven by the wind, causing the fixed rod 82 and the protective cover 83 to rotate. The first and second ball bearings are used to reduce the friction between the protective cover 83 and the crimp nut 81 and the support ring 86. During the rotation, the protective cover 83 is brushed away by centrifugal force, achieving self-cleaning of the protective cover 83. The protective cover 83 is used to protect the insulating center column 1 and the insulating disc 2, achieving dustproof and waterproof protection for the equipment.

[0028] It should be noted that, in the use of this waterproof and dustproof outdoor surge arrester, the fixing plate 3 is first fixed to the designated position using bolts 10. The anti-slip pad 6 is used to enhance the friction between the fixing plate 3 and the installation position, improving installation stability. Then, the installation angle of the outdoor surge arrester is adjusted using the angle adjustment mechanism 4, which facilitates adjustment of the installation angle according to actual needs. After the installation angle is adjusted, the support ring 86 is threaded onto the top screw 7, and then the protective cover 83 is fitted onto the top screw 7, ensuring that the bottom of the limiting sleeve 85 on the protective cover 83 is slidably installed onto the second screw. Inside the limiting groove 88, the crimp nut 81 is then threaded onto the top screw 7, and the crimp nut 81 is used to crimp and fix it to the top of the protective cover 83. At the same time, it ensures that the top of the limiting sleeve 85 is slidably connected to the bottom of the first limiting groove 87. When the wind blows, the wind blows the fan blade 84, which drives the fixing rod 82 and the protective cover 83 to rotate. The first ball and the second ball are used to reduce the friction between the protective cover 83 and the crimp nut 81 and the support ring 86. During the rotation, the protective cover 83 is brushed off by the centrifugal force, thus achieving the self-cleaning of the protective cover 83.

[0029] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
