Description

Technical Field

[0001] The utility model relates to the technical field of lightning protection devices, in particular to a lightning protection device installed in power transmission and transformation. Background Art

[0002] The lightning arrester is connected to the ground through a wire, forming an equipotential difference with the ground. It uses its own height to increase the electric field strength to the limit value, causing the electric field of the lightning cloud to be distorted, and begins to ionize and conduct a downward leader discharge. The lightning arrester produces a tip discharge under the action of the strong electric field, forming an upward leader discharge. The two combine to form a lightning path, which is then discharged into the earth to achieve the effect of lightning protection. Since multiple power transformations are required in the process of current transmission, the transmission of current is called power transmission and transformation. During the installation of power transmission and transformation, corresponding lightning arresters are required to protect the power transmission and transformation installation structure.

[0003] The lightning protection devices currently used in the field of power transmission and transformation installations inevitably include lightning rods or lightning terminals and their supporting installation structures. Lightning rods and lightning terminals are exposed to the outside world for a long time and are easily obscured by dust and rust. As the thickness of dust adhesion gradually increases, it will affect the lightning-attracting effect of lightning rods or lightning terminals, and staff are required to climb to high places regularly to clean the dust on the surface of lightning rods or lightning terminals.

[0026] Reference Figure 1-Figure 3 , which is an embodiment of the utility model, provides a lightning protection device for power transmission and transformation installation, including: a main unit 100, a lightning protection cleaning unit 200 and a storage protection unit 300.

[0027] The main unit 100 includes a power transmission and transformation installation base 101, a hollow tube 102 fixedly installed at the center of the upper side wall of the power transmission and transformation installation base 101, and an extension tube 103 vertically slidably connected to the hollow tube 102, a lightning arrester ball 104 is fixedly installed on the top of the extension tube 103, and a plurality of groups of evenly distributed plug rods are installed on the lower side wall of the power transmission and transformation installation base 101;

[0028] The lightning protection cleaning unit 200 includes a liquid storage box 201 sleeved on the outside of the hollow cylinder 102 and a transition pipe 202 located on the upper side of the liquid storage box 201 and fixedly connected to the liquid storage box 201. The outer wall of the hollow cylinder 102 is fixedly connected with an auxiliary support block 207, and the lower side wall of the liquid storage box 201 is fixedly connected with an annular embedded block 208. The auxiliary support block 207 is provided with an embedded groove matching the annular embedded block 208. Through the coordinated use of the auxiliary support block 207 and the annular embedded block 208, the liquid storage box 201 connected to the spray hood 205 and the outer wall of the hollow cylinder 102 on the transition pipe 202 can be disassembled more conveniently without replacing the entire set of lightning protection devices. A water pump 207 connected to the transition pipe 202 is fixedly installed in the liquid storage box 201. 03. The transition pipe 202 is fixedly connected to the spray hood 205 through multiple groups of evenly distributed liquid-passing pipes 204. Multiple groups of evenly distributed spray holes 206 are provided on one side of the spray hood 205 close to the lightning-receiving ball 104. A transparent observation window is embedded in the side wall of the liquid storage box 201. The diameter of the opening at one end of each spray hole 206 close to the lightning-receiving ball 104 is larger than the diameter of the opening at the other end of the spray hole 206. The setting of the transparent observation window can more conveniently observe the remaining amount of cleaning liquid in the liquid storage box 201.

The first bevel gear 303 and the second bevel gear 304 are both provided with evenly distributed anti-slip grooves, and the first bevel gear 303 and the second bevel gear 304 are both made of manganese steel material. The setting of the anti-slip grooves improves the stability of the first bevel gear 303 and the second bevel gear 304. The second bevel gear 304 has good transmission stability. The first bevel gear 303 and the second bevel gear 304 made of manganese steel have good wear resistance and good extrusion capacity, thereby extending the service life of the first bevel gear 303 and the second bevel gear 304.

The lifting nut 305 is fixedly connected to the lower end wall of the extension cylinder 103 through multiple groups of evenly distributed lifting rods 306, and the lower end wall of the extension cylinder 103 is provided with an opening that matches the threaded rod 302.

[0030] During use, when the dust and rust attached to the surface of the lightning receptor 104 gradually increase in thickness, the water pump 203 is started, and the cleaning liquid in the liquid storage box 201 sequentially passes through the transition pipe 202, the liquid pipe 204, the spray cover 205 and the spray hole 206 to clean the dust and rust attached to the surface of the lightning receptor 104, ensuring that the surface of the lightning receptor 104 is always kept in a relatively clean state, effectively solving the defect that the lightning attracting effect of the lightning receptor 104 is reduced due to the attachment of dust or rust, and there is no need for the staff to climb to a high place to manually clean the lightning receptor 104;

[0031] When the entire lightning protection device needs to be transported and disassembled, the output shaft of the driving motor 301 can be controlled to reverse, and the first bevel gear 303 fixedly connected thereto drives the threaded rod 302 to rotate through the second bevel gear 304, and the lifting nut 305 threadedly connected to the threaded rod 302 drives the lightning-receiving ball 104 and the extending tube 103 to retract into the hollow tube 102 through the jacking rod 306, so that the lightning-receiving ball 104 can be stored and protected to prevent the lightning-receiving ball 104 from being damaged during transportation. It can be retracted in the hollow tube 102, saving space occupancy and facilitating transportation and carrying.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
