Description

Technical Field

[0001] The present invention relates to the technical field of lightning arresters, and specifically to a lightning arrester with stable operation and its installation method. Background Art

[0002] With the rapid development of Internet technology, the Internet has become an indispensable tool for people's life and work. However, when natural lightning occurs, it will cause induced current surges in power and communication lines, damaging equipment. The reasons are that on the one hand, the internal structure of electronic equipment is highly integrated, such as ultra-large scale integrated circuit chips, which results in a decrease in the withstand voltage and over-current withstand level of the equipment, and a decrease in the tolerance to lightning such as induced lightning or switching overvoltage surges. On the other hand, due to the increase in the signal source paths, the system is more vulnerable to the intrusion of lightning waves than before, and the surge voltage can enter the computer equipment through power lines or signal lines and other channels.

[0003] After retrieval, a Chinese patent with the patent publication number CN215681785U discloses a two-in-one lightning arrester with stable installation, including a mounting plate. The front and back of the top of the mounting plate are both fixedly connected with slide rails. The top of the mounting plate is movably installed with a lightning arrester body. The front and back of the bottom of the lightning arrester body are both fixedly connected with sliders slidably connected to the slide rails. The top of the mounting plate is fixedly connected with a fixing plate located on the left side of the lightning arrester body. The left side of the lightning arrester body is fixedly connected with a metal rod. For this two-in-one lightning arrester with stable installation, through the sliding connection of the slider and the slide rail, the lightning arrester body can be horizontally slid on the slide rail through the slider, so that the lightning arrester body can be quickly installed and disassembled. Before the lightning arrester body moves horizontally on the slide rail through the slider, it is necessary to press the lightning arrester body hard to make the rollers in close contact with the mounting plate, so that the left spring is compressed, and then the slider can slide on the slide rail.

[0004] However, the above design still has deficiencies. In the above design, the installation of the lightning arrester is achieved through the elasticity of the spring. Although the operation is simple, the elasticity of the spring is reciprocating, and it is difficult to effectively fix the lightning arrester stably, which will reduce the stability during the operation of the lightning arrester and the use effect is poor.

[0005] The above information disclosed in this background art is only used to increase the understanding of the background art of the present application, and should not be regarded as an admission or an indication in any form that this information constitutes the prior art known to those of ordinary skill in the art.

[0024] Please refer to Figure 1-8 , an embodiment provided by the present invention: a lightning arrester with stable operation, including a base 3. A support plate 2 is arranged on the top of the base 3. A vertical plate 1 is fixedly connected to the top of the support plate 2. A limiting chute 10 is formed on the outer wall of the right side of the vertical plate 1. A limiting slider 11 is movably arranged inside the limiting chute 10. A lightning arrester body 5 is fixedly connected to the right side of the limiting slider 11. A positioning groove 13 is formed on the upper surface of the support plate 2 at the bottom of the lightning arrester body 5. A positioning block 12 is movably arranged inside the positioning groove 13, and the top of the positioning block 12 is fixedly connected to the bottom of the lightning arrester body 5. A threaded groove 22 is formed on the outer wall of the right side of the support plate 2. A hexagonal screw head 21 is rotatably arranged inside the threaded groove 22. A threaded cover 9 is rotatably arranged at the notch of the threaded groove 22 on the right side of the hexagonal screw head 21. An abutting block 20 is fixedly connected to the left side of the threaded cover 9. A first bidirectional screw rod 16 is fixedly connected to the left side of the hexagonal screw head 21 through a fixing rod. A moving block 15 is threadedly connected to the outer wall of the first bidirectional screw rod 16. A cross bar 17 is movably arranged through the lower end surface of the moving block 15. A transmission plate 14 is fixedly connected to the top of the moving block 15. A jack 19 is formed on the outer wall of the positioning block 12 on the side where the two transmission plates 14 are away from each other. A plug rod 18 is movably arranged inside the jack 19, and the plug rod 18 is fixedly connected to the outer wall close to the transmission plate 14; Specifically, as Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown in the figure, when in use and when the lightning arrester body 5 needs to be installed, place the lightning arrester body 5 above the support plate 2, align the limit slider 11 with the limit chute 10, and align the positioning block 12 with the positioning groove 13. Then, move the lightning arrester body 5 downward until the positioning block 12 is inserted into the positioning groove 13 and the limit slider 11 slides into the limit chute 10. Then, use a tool to rotate the hexagonal screw head 21. The rotation of the hexagonal screw head 21 drives the first bidirectional screw rod 16 to rotate through the fixing rod. The rotation of the first bidirectional screw rod 16 drives the two moving blocks 15 to move in a direction away from each other. The movement of the two moving blocks 15 drives the two transmission plates 14 to move. The movement of the two transmission plates 14 drives the insertion rod 18 to move towards the insertion hole 19 until the insertion rod 18 is inserted into the insertion hole 19, thereby completing the fixation of the positioning block 12 and further completing the installation of the lightning arrester body 5. The operation is simple and the installation efficiency is high. It solves the problem that when installing the lightning arrester through the elasticity of the spring, although the operation is simple, the elasticity of the spring is reciprocating, making it difficult to effectively and stably fix the lightning arrester, which will reduce the stability during the operation of the lightning arrester and result in poor use effect. Among them: Through the settings of the threaded cover 9, the abutting block 20, and the threaded groove 22, after the installation of the lightning arrester body 5 is completed, screw the threaded cover 9 into the threaded groove 22. During this process, the abutting block 20 will move towards the hexagonal screw head 21 until it contacts the hexagonal screw head 21 and generates a certain extrusion force on it, thereby avoiding the rotation of the hexagonal screw head 21 and further improving the stability of the lightning arrester body 5 after installation.

[0025] A positive and negative motor 7 is installed on the right side of the base 3. The upper surface of the base 3 extends to the inside to form an installation groove 23. A second bidirectional screw rod 30 is rotatably arranged at the lower end inside the installation groove 23, and one end of the second bidirectional screw rod 30 is fixedly connected to the output end of the positive and negative motor 7. The outer wall of the second bidirectional screw rod 30 is threadedly connected with a threaded block 31. The lower end surface of the threaded block 31 penetrates and is movably provided with a limit rod 27. The top of the threaded block 31 is fixedly connected with a second hinge block 29. The top of the second hinge block 29 is hinged with a connecting rod 26. The top of the connecting rod 26 is hinged with a first hinge block 25. The top of the first hinge block 25 is fixedly connected with a moving plate 28. The top of the moving plate 28 is fixedly connected with a transmission rod 24, and the top of the transmission rod 24 is fixedly connected to the bottom of the support plate 2. A control panel 6 is installed on the front end surface of the base 3. Damping shock absorbers 4 are installed at the four corners of the bottom of the base 3, and the bottom of the damping shock absorbers 4 is fixedly connected with a bottom plate 8; Specifically, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 and Figure 8As shown, during use, during the operation of the lightning arrester body 5, the output end of the forward and reverse motor 7 can drive the second bidirectional screw 30 to rotate. The rotation of the second bidirectional screw 30 drives the two threaded blocks 31 to move in the direction of approaching or separating from each other. The movement of the two threaded blocks 31 drives the movement of the two second hinge blocks 29. The movement of the two second hinge blocks 29 drives the moving plate 28 to move upward or downward through the mutual cooperation of the first hinge block 25 and the connecting rod 26. The movement of the moving plate 28 drives the support plate 2 to move upward or downward through the transmission rod 24. The movement of the support plate 2 finally drives the lightning arrester body 5 to move upward or downward. By facilitating the adjustment of the working height of the lightning arrester body 5, it is thus convenient to better meet the usage requirements of different scenarios, and further improve the convenience of the device; Among them: Through the mutual cooperation of multiple damping shock absorbers 4, shock absorption protection can be achieved for the lightning arrester body 5, thereby further improving the stability of the lightning arrester body 5 during operation.

[0026] The present invention also proposes an installation method for a lightning arrester with stable operation, including the following steps: S1: First, place the lightning arrester body 5 above the support plate 2, align the limit slider 11 on the lightning arrester body 5 with the limit chute 10, and align the positioning block 12 at the bottom of the lightning arrester body 5 with the positioning groove 13, and then move the lightning arrester body 5 downward; S2: Until the limit slider 11 slides into the limit chute 10 and the positioning groove 13 inserts into the positioning block 12, and then use a tool to rotate the hexagon head 21 until the insertion rod 18 inserts into the insertion hole 19, thereby completing the fixation of the positioning block 12 and further completing the installation of the lightning arrester body 5; S3: Then screw the threaded cover 9 into the threaded groove 22. During this process, the abutting block 20 will move towards the direction close to the hexagon head 21 until it contacts the hexagon head 21 and generates a certain extrusion force on it, thereby avoiding the rotation of the hexagon head 21 and further improving the installation effect of the lightning arrester body 5.

[0027] Working principle: In this application, when the lightning arrester body 5 needs to be installed, place the lightning arrester body 5 above the support plate 2, align the limit slider 11 with the limit chute 10, and align the positioning block 12 with the positioning groove 13. Then, move the lightning arrester body 5 downward until the positioning block 12 is inserted into the positioning groove 13 and the limit slider 11 slides into the limit chute 10. Then, use a tool to rotate the hexagonal screw head 21. The rotation of the hexagonal screw head 21 drives the first bidirectional screw rod 16 to rotate through the fixing rod. The rotation of the first bidirectional screw rod 16 drives the two moving blocks 15 to move in opposite directions. The movement of the two moving blocks 15 drives the two transmission plates 14 to move. The movement of the two transmission plates 14 drives the insertion rod 18 to move towards the jack 19 until the insertion rod 18 is inserted into the jack 19, thus completing the fixation of the positioning block 12 and further completing the installation of the lightning arrester body 5. The operation is simple and the installation efficiency is high. Secondly, during the use of the lightning arrester body 5, the output end of the forward and reverse motor 7 can drive the second bidirectional screw rod 30 to rotate. The rotation of the second bidirectional screw rod 30 drives the two threaded blocks 31 to move in opposite directions or towards each other. The movement of the two threaded blocks 31 drives the two second hinge blocks 29 to move. The movement of the two second hinge blocks 29 drives the moving plate 28 to move upward or downward through the mutual cooperation of the first hinge block 25 and the connecting rod 26. The movement of the moving plate 28 drives the support plate 2 to move upward or downward through the transmission rod 24. The movement of the support plate 2 finally drives the lightning arrester body 5 to move upward or downward, which is convenient for adjusting the working height of the lightning arrester body 5, so as to better meet the usage requirements of different scenarios and further improve the convenience of the device. Finally, through the mutual cooperation of multiple damping shock absorbers 4, shock absorption protection can be achieved for the lightning arrester body 5, thereby further improving the stability of the lightning arrester body 5 during operation.
