Cleaning device for insulation of transmission tower

The present invention relates to a cleaning device, and more particularly to a cleaning device for an insulation barrier of a transmission tower.

Now that society is rich, the demand for electricity is increasing, and the high-voltage power generated by the power generation terminals (for example, nuclear power plants, thermal power plants, hydroelectric power plants, wind power plants, etc.) (for example, high voltages such as 161KV and 345KV) must be Through the transmission and distribution equipment, transfer to the required area and then step down, etc., in order to provide end users.

Referring to FIG. 1, in order to ensure the safety of power transmission, a steel transmission tower 100 of several tens of meters high is used, and a plurality of insulation strings 101 are used as insulation intervals to erect most of the transmission and distribution lines 102.

However, factors such as weather (such as rain, fog, wind, etc.) and the environment (salts of salt, smoke, exhaust gas, etc.) gradually degrade the insulation string 101 over time, causing the insulation barrier. The insulation damage of the string 101 generates leakage current, and in severe cases, the grounding accident of the line may affect the power supply.

In order to maintain the power supply quality, most of the power companies climb the pipeline 12 to the steel transmission tower 100 with the manpower 11 carrying the pipeline 12, and then pressurize the insulation string 101 with the pressurizing device 13 to pressurize the liquid. But this practice is not only Time-consuming and labor-intensive, more prone to accidents

In order to improve the above-mentioned deficiency, the related art has developed a technique of cleaning the insulating insult string 101 by the helicopter 14 as shown in FIG. 2, the Republic of China No. M282917. Although the time for climbing the steel transmission tower 100 can be saved, the use of the helicopter 14 is not only costly, but if it is not properly operated, it not only causes damage to personnel and equipment, but also damages the steel transmission tower 100 and loses at the same time. The distribution line 102 or the insulation string 101 affects the power supply.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a cleaning device for an insulation barrier of a transmission tower which can avoid accidents at a low cost.

Therefore, in the cleaning device for the insulation of the transmission tower of the present invention, the transmission tower comprises a tower body and an insulation barrier disposed on the tower body. The cleaning device comprises a transport unit disposed on the tower body and extending in a height direction of the tower body to transport liquid, and a cleaning unit detachably connecting the transport sheet.

The cleaning unit includes a connecting pipe detachably connecting the conveying unit and communicating with the conveying unit, and a spraying mechanism that communicates with the connecting pipe and can spray liquid toward the insulating barrier.

The utility model has the advantages that the cleaning operation of the insulation is carried out by using the conveying unit provided on the tower body and the cleaning unit detachably connected to the conveying unit, and the work safety which may occur in climbing and working at height is not only avoided. Accidents and low construction costs. At the same time, the cleaning unit that is detachably connected to the conveying unit is more convenient for subsequent replacement and maintenance.

For convenience of explanation, the following is a description of cleaning one of the insulating barriers 202.

The cleaning device 2 includes a transport unit 21 disposed on the tower body 201 and extending in the height direction of the tower body 201 to transport liquid, and a cleaning unit 22 detachably connecting the transport unit 21.

Referring to Figures 3, 4 and 5, the transport unit 21 includes a transport tube 211 disposed in the tower body 201 and extending in the height direction of the tower body 201, and a dustproof member 215. The conveying pipe 211 has a connecting end 212 away from the ground, a liquid supply end 213 opposite to the connecting end 212 and adjacent to the ground, and a coupling mechanism 214 at the liquid supply end 213. The dustproof member 215 is detachably sealed with the liquid supply end 213.

In this embodiment, the coupling mechanism 214 is a thread. Of course, it may be a quick connector in practical applications, and is not limited to the disclosure of the embodiment.

In the present embodiment, the conveying pipe 211 is made of JIS SUS304 stainless steel and has a diameter of 10 mm, and is fixed to the tower body 201 by a U-shaped pipe clamp (not shown), and the connecting end 212 is spaced from the ground by about 3 Metric to avoid touching or stealing.

The cleaning unit 22 includes a connecting tube 221 detachably connected to the connecting end 212 of the conveying pipe 211 and communicating with the conveying pipe 211. And a spray mechanism 225 that connects the connecting tube 221. The spray mechanism 225 has a water mist nozzle 226 that communicates with the connecting tube 221 and can spray liquid toward the insulating barrier 202.

In the present embodiment, the connecting tube 221 is made of JIS SUS304 stainless steel and has a diameter of 10 mm, and the water mist nozzle 226 is 1.5 m apart from the insulating barrier 202. However, in actual use, the distance between the water mist nozzle 226 and the insulating barrier 202 may be determined according to the safety distance requirement of the voltage of the power transmitted by each power transmission and distribution line 102, and is not limited to 1.5 m.

Referring to FIG. 6, and referring back to FIGS. 4 and 5, when the cleaning operation of the insulating barrier 202 is to be performed, the worker only needs to transport a liquid pressurizing device A to the vicinity of the tower 201 and remove the dustproof member 215. And combining the liquid pressurizing device A with the coupling mechanism 214 at the liquid supply end 213, lifting the bonding force of the liquid pressurizing device A and the conveying pipe 211, and the liquid supply end 213 of the conveying pipe 211 It can be in communication with the liquid pressurizing device A.

After the liquid is pressurized by the liquid pressurizing device A, the water mist nozzle 226 is further formed by the water transfer nozzle 226 to form a pressurized water mist sprayed toward the insulating barrier 202. The pressurized water mist can not only clean the surface of the insulating barrier 202 by the flushing force, but also form an artificial rain-like environment in a local space near the insulating barrier 202 to wet the insulating barrier 202. The dirt on the insulating barrier 202 is dissolved, and the insulating barrier 202 is cleaned to keep the surface of the insulating barrier 202 clean.

After the cleaning operation is completed, the liquid supply end 213 of the conveying pipe 211 is separated from the liquid pressing device A, and the dust removing member 215 is resealed to the liquid supply end 213 to prevent the liquid supply end 213 from being blocked or External force Defaced.
