[0028] See also Figure 1 In one embodiment of the present invention, the present invention provides a zinc oxide lightning arrester for power facilities, including: a base 1, a main lightning rod 2, a supporting component 3 and a cleaning component 4. The lower end of the main lightning rod 2 can be rotatably inserted on the base 1. The supporting component 3 is rotatably arranged on the base 1, and the upper and lower ends of the supporting component 3 are respectively correspondingly installed on the upper and lower ends of the main lightning rod 2. The cleaning component 4 is installed on the supporting component 3, and the cleaning component 4 is arranged on one side of the main lightning rod 2. Among them, the supporting component 3 and the cleaning component 4 are adjusted to correspond to the wind direction, so that the supporting component 3 is supported on the opposite side of the main lightning rod 2 to the wind, and the cleaning component 4 rotates and sprays water to clean the surface of the main lightning rod 2 under the drive of the wind.

[0029] It is not difficult to find from the above content that when the zinc oxide lightning arrester of the present invention is used, the cleaning component 4 is installed on the main lightning rod 2, and then the supporting component 3 is installed on the main lightning rod 2. Finally, the main lightning rod 2 is installed on the base 1. In addition, the supporting component 3 is also rotatably installed on the base 1. When affected by wind force, the supporting component 3 can automatically adjust its position so that the supporting component 3 can quickly reach the supporting position corresponding to the main lightning rod 2 to resist the influence of wind force on the main lightning rod 2, and prevent the main lightning rod 2 from loosening, deforming, etc. caused by wind force when connected to the base 1. After the supporting component 3 reaches the supporting position corresponding to the main lightning rod 2, the cleaning component 4 will be further adjusted to the corresponding position affected by wind force. Thereby, the cleaning work of the main lightning rod 2 is realized by utilizing the effect of wind on the cleaning component 4 to drive the cleaning component 4 to rotate, so as to solve the problem that when the surface of the main lightning rod 2 is impacted by the wind-carried adsorbed polluted particles, resulting in a large amount of polluted particles being adsorbed on the surface of the main lightning rod 2, the cleaning component 4 can effectively realize the water spraying and rotation cleaning treatment of the surface of the main lightning rod 2 to ensure the cleanliness of the surface of the main lightning rod 2, thereby extending the service life of the main lightning rod 2.

[0030] like Figure 1 and Figure 2 As shown, the supporting assembly 3 includes: an upper bracket 31 and a lower bracket 32, the upper bracket 31 is connected to the upper end of the main lightning rod 2, the lower bracket 32 ​​is connected to the lower end of the main lightning rod 2, and the length of the upper bracket 31 is smaller than the length of the lower bracket 32; a support member 33, one end of the support member 33 is connected to the upper bracket 31, and the other end of the support member 33 is connected to the lower bracket 32; a guide plate 34, the guide plate 34 is an annular structure, the guide plate 34 is rotatably arranged on the base 1, and the lower end of the support member 33 is installed on the guide plate 34; and a tail wing plate 35, one end of the tail wing plate 35 is connected to one end of the upper bracket 31 corresponding to the support member 33, and the tail wing plate 35 is vertically arranged.

[0031] In one embodiment of the present invention, when the main lightning rod 2 is installed, the supporting assembly 3 is installed on the upper end of the main lightning rod 2 through one end of the upper bracket 31, and is installed on the lower end of the main lightning rod 2 through one end of the lower bracket 32. And then the upper end of the support member 33 is connected to the other end of the upper bracket 31, and the lower end of the support member 33 is connected to the other end of the lower bracket 32. Thus, the upper bracket 31, the lower bracket 32 ​​and the support member 33 form a supporting structure for the main lightning rod 2. And when subjected to wind force, in order to ensure that the supporting structure composed of the upper bracket 31, the lower bracket 32 ​​and the support member 33 is always supported on the opposite side of the wind force acting on the main lightning rod 2. The lower end of the support member 33 is also installed on the guide plate 34, and the guide plate 34 is rotatably installed on the base 1. Thus, when the wind acts on the tail wing plate 35, the tail wing plate 35 is arranged along the wind direction, and the guide plate 34 is rotated and adjusted to the corresponding position on the base 1, and this position enables the main lightning rod 2 and the support member 33 to be arranged side by side along the wind direction, and the support member 33, the upper bracket 31 and the lower bracket 32 ​​form a supporting structure to support the main lightning rod 2 in the reverse direction of the wind direction, solving the problem of shaking and loosening of the main lightning rod 2 due to the wind. Specifically, when the tail wing plate 35 is connected to the upper bracket 31, the tail wing guide rod 36 can be firstly set on the top of the main lightning rod 2, or the tail wing guide rod 36 can be directly welded to the upper bracket 31. The tail wing plate 35 is then installed on the other end of the tail wing guide rod 36 by riveting or screw connection, and the tail wing plate 35 is arranged vertically so that under the action of wind, the tail wing plate 35 can rotate with the guide plate 34 to adjust the supporting position of the support member 33 on the main lightning rod 2.

[0032] like Figure 2 As shown, the support member 33 is an auxiliary lightning rod 330 , the upper end of the auxiliary lightning rod 330 is electrically connected to the upper end of the main lightning rod 2 through the upper bracket 31 , and the lower end of the auxiliary lightning rod 330 is electrically connected to the lower end of the main lightning rod 2 through the lower bracket 32 ​​.

[0033] In one embodiment of the present invention, the support member 33 can be a rigid member to improve the stability of the support when supporting the main lightning rod 2. Of course, the support member 33 can also be an auxiliary lightning rod 330, which can be used to assist in guiding lightning when the main lightning rod 2 is working. When the auxiliary lightning rod 330 is working, it can be used together with the main lightning rod 2. Of course, the auxiliary lightning rod 330 can also work alone, that is, when the main lightning rod 2 is damaged, it can be used as a backup to ensure the lightning protection effect. Moreover, the auxiliary lightning rod 330 can be used temporarily and used as a backup again after replacing the main lightning rod 2. When the auxiliary lightning rod 330 is used, it can also be cleaned by setting a cleaning component 4, which will not be repeated here. When determining whether the main lightning rod 2 is abnormal, it can be determined whether the main lightning rod 2 has discharge flashover traces by checking the action of the discharge counter corresponding to the main lightning rod 2 after a thunderstorm.

[0034] In order to install the auxiliary lightning rod 330, the auxiliary lightning rod 330 can be set to an inclined angle of less than 15 degrees for working use.

[0035] See also Figure 3 In a preferred embodiment, when the auxiliary lightning rod 330 is installed on the guide plate 34, in order to ensure the convenience of installation, a thumb groove 341 can be opened on one side of the guide plate 34. When the lower end of the auxiliary lightning rod 330 needs to be installed, the lower end of the auxiliary lightning rod 330 can be directly inserted into the thumb groove 341, and then the installation screw is threadedly connected to the lower end of the auxiliary lightning rod 330 and fastened to the lower surface of the thumb groove 341 to ensure the installation stability between the auxiliary lightning rod 330 and the guide plate 34.

[0036] like Figure 4 and Figure 5 As shown, the supporting assembly 3 also includes: a power-off device 37, which is installed on the upper bracket 31. The upper bracket 31 is provided with a socket 311 corresponding to the power-off device 37. The power-off device 37 is slidably arranged in the socket 311 to open and close the circuit between the upper end of the auxiliary lightning rod 330 of the upper bracket 31 and the upper end of the main lightning rod 2.

[0037] In one embodiment of the present invention, when the support member 33 is an auxiliary lightning rod 330, in order to ensure that the auxiliary lightning rod 330 does not work under normal conditions, and when it is determined that the main lightning rod 2 is abnormal, it is replaced for temporary use. A socket 311 that can disconnect the upper end of the main lightning rod 2 and the upper end of the auxiliary lightning rod 330 is provided on the upper bracket 31. And if it is necessary to establish an electrical connection, the power-off device 37 can be inserted into the socket 311 to achieve the line conduction of the upper bracket 31, thereby achieving the electrical connection between the upper end of the main lightning rod 2 and the upper end of the auxiliary lightning rod 330, and temporarily enabling the auxiliary lightning rod 330 to work.

[0038] Furthermore, the upper bracket 31 includes: an upper main bracket 312, which is a component made of insulating material, the upper end of the auxiliary lightning rod 330 and the upper end of the main lightning rod 2 are connected through the upper main bracket 312, and the socket 311 is arranged on the upper main bracket 312; a first conductive member 313, which is arranged on the upper main bracket 312, and one end of the first conductive member 313 is electrically connected to the upper end of the main lightning rod 2, and the other end of the first conductive member 313 extends to one side of the socket 311; and a second conductive member 314, which is arranged on the upper main bracket 312, and one end of the second conductive member 314 is electrically connected to the upper end of the auxiliary lightning rod 330, and the other end of the second conductive member 314 extends to the other side of the socket 311; after the power-off device 37 is inserted into the socket 311, the first conductive member 313 is electrically connected to the second conductive member 314 through the power-off device 37.

[0039] In one embodiment of the present invention, the upper main bracket 312 can be a rigid and insulating structural member. The socket 311 can be opened in the middle of the upper main bracket 312, and can disconnect the first conductive member 313 and the second conductive member 314. Specifically, the first conductive member 313 and the second conductive member 314 can be conductive sheets embedded in the surface of the upper main bracket 312 along the length direction of the upper main bracket 312. And one end of the first conductive member 313 is connected to the upper end of the main lightning rod 2, and the other end is connected to one side of the socket 311 or directly forms an L shape and is inserted on a side wall in the socket 311. Similarly, one end of the second conductive member 314 is connected to the upper end of the auxiliary lightning rod 330, and the other end is connected to the other side of the socket 311 or is directly formed into an L shape and inserted on the inner wall of the other side of the socket 311. Then, when the power-off device 37 is inserted into the socket 311, it can directly contact the ends of the first conductive member 313 and the second conductive member 314, thereby forming a conductive connection.

[0040] like Figure 5 As shown, the power-off device 37 includes: a conductive block 371, which is slidably inserted into the socket 311 and is a component made of conductive material; and a driver 372, which is arranged above the conductive block 371 and connected to the upper main bracket 312, and the power output end of the driver 372 is connected to the conductive block 371 to drive the conductive block 371 to slide and insert into the socket 311.

[0041] In one embodiment of the present invention, when the power-off device 37 is slidably inserted into the socket 311 to form the conductive / disconnected connection between the first conductive member 313 and the second conductive member 314, the power output end of the driver 372 installed on the upper main bracket 312 drives the conductive block 371 to move up and down in the socket 311 to achieve disconnection / conduction. Specifically, when the driver 372 takes the conductive block 371 away from the socket 311 upward or downward, the conductive block 371 is in a separated state from the first conductive member 313 and the second conductive member 314, thereby achieving the purpose of power off. When the driver 372 takes the conductive block 371 and inserts it into the socket 311, the conductive block 371 is in a contact state with the first conductive member 313 and the second conductive member 314, thereby achieving the purpose of conduction. Specifically, the driver 372 may include a push rod motor, a solar photovoltaic panel, a backup battery, etc. That is, by using the solar photovoltaic panel to convert solar energy into electrical energy, the power is stored by the backup battery, and provided to the push rod motor to drive the conductive block 371 to move up and down.

A water pump is arranged in the water tank 46, and the water outlet end of the water pump is connected with each water outlet 45 through a pipeline.

[0043] In one embodiment of the present invention, when the cleaning assembly 4 is working, the wind driver 41 will follow the position adjustment of the tail wing plate 35 and also reach a position corresponding to the wind direction to obtain the wind force to the maximum extent, and convert the wind force into power output and transmit it to the driven disk 42. Further, the driven disk 42, which is sleeved on the main lightning rod 2 and rotatably connected to the bottom of the wind driver 41, rotates around the main lightning rod 2 with the rotating frame 43, and the vertical bracket 44 connected to the inner side of the rotating frame 43 and the bristles 47 thereon will also rotate with the rotating frame 43. If there is a preset amount of rainwater in the water tank 46, the vertical bracket 44 will be driven to move toward the side of the main lightning rod 2, so that the bristles 47 on the vertical bracket 44 contact the outer wall of the main lightning rod 2, so that the surface of the main lightning arrester 2 can be cleaned on rainy days or non-rainy days. Moreover, due to the water stored in the water tank 46, the rainwater in the water tank 46 can be pumped to each water outlet 45 arranged along the height direction of the main lightning rod 2 through a pipeline by utilizing the water pump (not shown in the figure) in the water tank 46, and sprayed from the water outlet 45 to the surface of the main lightning rod 2, so as to realize the cleaning of the surface of the main lightning rod 2 by using the brush 47 while spraying water, until the water storage amount in the water tank 46 is lower than the preset amount, the water tank 46 rises to the original position, at which time the brush 47 will leave the surface of the main lightning rod 2, and the surface cleaning of the main lightning rod 2 is finished. Furthermore, the water pump can also be electrically connected to the backup battery.

The rotating wind impeller 413 further transmits power to the driving wheel 415, thereby driving the driven disc 42 to rotate. Specifically, the driving wheel 415 and the driven disc 42 are both gear structures.

[0046] like Figure 6 and Figure 7 As shown, the water tank 46 includes: a box body 461, a guide rod 462 is connected to the bottom of the box body 461, the lower end of the guide rod 462 is slidably inserted into the rotating frame 43, and a first spring 463 is provided on the guide rod 462 between the bottom of the box body 461 and the rotating frame 43; a vertical guide block 464, the vertical guide block 464 is arranged at the bottom of the box body 461, and the lateral dimension of the top side of the vertical guide block 464 is larger than the lateral dimension of the bottom side of the vertical guide block 464; wherein, a protrusion 465 is laterally provided on one side of the vertical bracket 44, and the end of the protrusion 465 is abutted against one side of the vertical guide block 464, so that when the vertical guide block 464 is located on the top side of the vertical guide block 464, the bristles 47 contact the outer wall of the main lightning rod 2, and when the vertical guide block 464 is located on the bottom side of the vertical guide block 464, the bristles 47 leave the outer wall of the main lightning rod 2.

[0047] In one embodiment of the present invention, when the water tank 46 drives the vertical bracket 44 on the rotating frame 43 to move toward the main lightning rod 2, when rainwater enters the box 461 from the top opening of the box 461, the weight of the box 461 will gradually increase, the first spring 463 will gradually be compressed, and the box 461 will gradually descend. When the box 461 descends, the vertical guide block 464 at its bottom will also gradually descend vertically. The side of the vertical guide block 464 close to the protrusion 465 gradually protrudes toward the side of the protrusion 465, thereby pushing the protrusion 465 to move toward the main lightning rod 2, so that the vertical bracket 44 moves with the bristles 47 to contact the surface of the main lightning rod 2 for cleaning.

[0048] Furthermore, when the vertical bracket 44 is installed on one side of the bottom of the rotating frame 43, two plug rods can be fixedly installed on both sides of the top of the vertical bracket 44, and the other ends of the plug rods are inserted into the rotating frame 43, so that the vertical bracket 44 can slide back and forth at the bottom of the rotating frame 43 along the plug rod direction. At the same time, a second spring is sleeved on the plug rod, one end of the second spring is connected to the vertical bracket 44, and the other end is connected to the rotating frame 43. And when the protrusion 465 is against the lower end of the vertical guide block 464, the second spring can pull the vertical bracket 44 to the side away from the main lightning rod 2 to prevent the bristles 47 from contacting the surface of the main lightning rod 2.

[0049] like Fig. 9 As shown, the present invention also provides an installation method for the zinc oxide lightning arrester for the above-mentioned power facility, comprising the following steps:

[0050] Install the cleaning component 4 on the main lightning rod 2, and make the cleaning side of the cleaning component 4 correspond to the side wall of the main lightning rod 2;

[0051] The supporting assembly 3 is sequentially installed on the upper and lower ends of the main lightning rod 2, and then the lower end of the main lightning rod 2 is inserted on the base 1, and the lower end of the supporting assembly 3 is rotated and inserted on the base 1;

[0052] The lower ends of the base 1 and the main lightning rod 2 are respectively installed in the waiting installation areas corresponding to the power facilities, so that under the action of wind, the supporting component 3 and the cleaning component 4 are adjusted to correspond to the wind direction, so that the supporting component 3 is supported on the opposite side of the main lightning rod 2 to the wind, and the cleaning component 4 rotates and sprays water to clean the surface of the main lightning rod 2 under the drive of wind.

[0053] In summary, the present invention can realize that under the action of wind, the supporting component 3 can automatically rotate to the opposite side of the main lightning rod 2 to support the wind force, thereby solving the problem that the main lightning rod 2 is tilted and bent due to the wind force, resulting in loose connection, which affects the service life of the main lightning rod 2 when the main lightning rod 2 is installed in a loose state for a long time. And when the supporting component 3 is used to support the main lightning rod 2, by using the auxiliary lightning rod 330 as the supporting member 33, it can be achieved that when the main lightning rod 2 is abnormal, the first conductive member 313 and the second conductive member 314 are connected through the power-off device 37 on the upper bracket 31, so that the auxiliary lightning rod 330 is used to enter a temporary working state, and the safety of electricity use is further ensured. Through the mutual cooperation between the main lightning rod 2, the supporting assembly 3 and the cleaning assembly 4, it can be achieved that after the supporting assembly 3 completes the adjustment of the supporting position, the cleaning assembly 4 can make the most of the wind power to drive the bristles 47 on the vertical bracket 44 to rotate around the main lightning rod 2. Moreover, the water storage amount in the water tank 46 gradually increases, the water tank 46 descends and drives the vertical bracket 44 to move toward the side of the main lightning rod 2, and makes the bristles 47 contact the main lightning rod 2 to clean the surface of the main lightning rod 2. Moreover, during cleaning, the water pump can also be controlled to pump the water in the water tank 46 to the water outlet 45 to spray onto the surface of the main lightning rod 2, so as to achieve the purpose of flushing and cleaning. When the amount of water in the water tank 46 decreases, the water tank 46 gradually moves upward, so that the bristles 47 will also leave the main lightning rod 2 to release the cleaning work. In the above manner, the main lightning rod 2 can be protected by the wind, and the auxiliary lightning rod 330 can be used to temporarily replace the main lightning rod 2, and the surface of the main lightning rod 2 can be cleaned by wind and rain to extend the service life of the main lightning rod 2. Therefore, the present invention effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.

[0054] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
