Description

Technical Field

[0001] This utility model relates to the field of UAV power grid insulator cleaning technology, and in particular to a UAV-based power grid insulator water cleaning device. Background Technology

[0002] In power systems, the cleanliness of grid insulators is crucial for their normal operation. Dirt and dust on the insulator surface not only reduce their insulation performance but can also lead to faults such as flashover and short circuits, severely impacting the stability and safety of the power system. Therefore, regular cleaning of grid insulators is a necessary maintenance measure.

[0003] Traditional methods for cleaning power grid insulators mainly involve manual cleaning or high-pressure water jet washing from the ground. However, these methods have many shortcomings. Manual cleaning is inefficient and poses safety risks when working at heights; while high-pressure water jet washing from the ground is limited by distance and angle, making it difficult to thoroughly clean all parts of the insulator.

[0004] With the continuous development of drone technology, using drones for power grid inspection and cleaning has become a trend. However, most existing drone cleaning devices have limited functions, low cleaning efficiency, and are not suitable for water cleaning of power grid insulators. Therefore, there is an urgent need in the market for a high-efficiency, safe drone device suitable for water cleaning of power grid insulators. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figures 1-5 A water cleaning device for power grid insulators based on drones includes a cleaning mechanism 2 installed at the bottom of a DJI FC30 carrier drone 1. The cleaning mechanism 2 includes a right-angle tee 201, a booster pump fixing plate 208, a servo motor fixing plate 215, and a folded carbon tube 218.

[0028] There are four right-angle tees 201. A first carbon tube 202 is installed between every two right-angle tees 201. A water tank 205 is installed on the four first carbon tubes 202. A water pumping pipe 206 is installed on the bottom of the water tank 205.

[0029] A booster pump 209 is mounted on the upper surface of the booster pump mounting plate 208, and the end of the water pipe 206 away from the water tank 205 is installed at the water pumping end of the booster pump 209.

[0030] A servo motor 216 is mounted on the upper surface of the servo motor mounting plate 215, and a variable diameter nozzle 214 is mounted on the output end of the servo motor 216.

[0031] The folded carbon tube 218 has a water supply pipe 213 inside. The end of the water supply pipe 213 away from the water tank 205 is installed at the water inlet of the variable diameter nozzle 214, and the end of the water supply pipe 213 away from the variable diameter nozzle 214 is installed at the water supply end of the booster pump 209.

[0032] The servo mounting plate 215 is mounted on the outer surface of the folded carbon tube 218 away from the booster pump 209 by two second O-rings 217.

[0033] Each of the four right-angle tees 201 has a second carbon tube 203 installed at its bottom, and each second carbon tube 203 has a T-shaped adapter 204 installed at its bottom end. All four T-shaped adapters 204 are installed on the landing gear at the bottom of the DJI FC30 carrier drone 1.

[0034] The bottom surface of the booster pump mounting plate 208 is mounted on the landing gear at the bottom of the DJI FC30 carrier drone 1 via four first U-shaped clips 207.

[0035] A carbon tube fixing plate 210 is installed at the bottom of the first carbon tube 202, and the end of the folded carbon tube 218 away from the servo motor 216 is installed on the upper surface of the carbon tube fixing plate 210 through two first O-rings 211.

[0036] The bottom surface of the carbon tube fixing plate 210 is mounted on the landing gear at the bottom of the DJI FC30 carrier drone 1 via two second U-shaped clips 212.

[0037] Reference Figure 3 and Figure 4 In some practical applications, the first carbon tube 202 has two M4 holes on both the front and rear ends, which are in the same positions as the M4 holes on the water tank 205. The water tank 205 is fixedly installed using four bolts. The booster pump 209 is fixedly installed on the booster pump mounting plate 208 using 3M strong double-sided Velcro.

[0038] Reference Figure 3 In some practical applications, the foldable carbon tube 218 is 80cm long and 16mm in diameter. The foldable carbon tube 218 has a 180° folding part in the middle, so as to realize the foldable carbon tube 218 for folding and storage.

[0039] Reference Figures 1-5 The entire device is connected by pneumatic joints and PU hoses for water flow.

[0040] Reference Figures 1-5In some practical applications, the DJI FC30 carrier drone 1 serves as the flight platform, with the cleaning mechanism 2 securely mounted on its bottom via a T-connector 204 and a second carbon tube 203. The water tank 205 in the cleaning mechanism 2 has a capacity of at least 10 liters, ensuring sufficient cleaning water for a single cleaning operation. The booster pump 209, model XYZ-100, has a maximum boosting capacity of 10 MPa, meeting the high-efficiency cleaning requirements of power grid insulators. The variable-diameter nozzle 214 features an adjustable orifice design with a maximum spray distance of 5 meters, ensuring coverage of power grid insulators of different sizes and shapes.

[0041] Reference Figures 1-5 In some practical applications, the drone operator first uses a remote controller to fly the drone above the power grid insulator to be cleaned and hover it in a suitable position. Then, the booster pump 209 is activated, drawing cleaning water from the water tank 205 through the water pipe 206. The pressurized water flow is then transmitted through the water pipe 213 to the variable diameter nozzle 214 for precise spray cleaning of the power grid insulator. During the cleaning process, the operator can adjust the pressure of the booster pump 209 and the orifice diameter of the variable diameter nozzle 214 according to the actual situation to adapt to different cleaning needs.

[0042] Reference Figures 1-5 In some practical applications, the foldable carbon fiber tube 218 of the cleaning mechanism 2 is made of high-strength carbon fiber material, which ensures sufficient strength while achieving a lightweight design. The folding function of the foldable carbon fiber tube 218 allows the cleaning mechanism 2 to be easily folded and stored when not in use, reducing the need for storage space and improving portability.

[0043] Working Principle: Before the cleaning operation begins, the operator will first conduct a pre-flight check and preparation of the DJI FC30 carrier drone 1. This ensures the drone's battery is fully charged and all components are functioning properly. Then, the cleaning mechanism 2 is securely installed on the drone's landing gear via the T-connector 204 and the second carbon tube 203. Simultaneously, ensure the folded carbon tube 218 is in the unfolded state so that the variable diameter nozzle 214 can accurately align with the insulator. After takeoff, the drone flies to the grid insulator to be cleaned using its built-in navigation system or remote control and hovers in a suitable position. During drone hovering, the operator will activate the booster pump 209. The booster pump 209 draws cleaning water from the water tank 205 through the water pipe 206 and pressurizes it to a pressure range suitable for the cleaning operation. The water tank 205 must be filled in advance to meet the cleaning requirements. The pressurized water flow is conducted to the variable diameter nozzle 214 through the water pipe 213. During this process, the operator can control the water flow intensity by adjusting the pressure of the booster pump 209. Simultaneously, during the water spraying process, the servo motor 216 controls the direction and spray angle of the variable-diameter nozzle 214, ensuring that the cleaning water jet can accurately spray all parts of the power grid insulator. By adjusting the orifice diameter of the variable-diameter nozzle 214, the intensity and shape of the water flow can be controlled to adapt to different cleaning needs, ensuring that the cleaning water flow can fully cover the surface of the insulator and effectively remove dirt and dust. Once the power grid insulator is thoroughly cleaned, the operator will turn off the booster pump 209 and stop the water spray. Subsequently, the drone is slowly withdrawn from the work site and returned to a safe take-off and landing area for subsequent maintenance and inspection. Throughout the cleaning process, the drone operator can control the servo motor 216 and the booster pump 209 in real time via remote control, achieving precise and efficient cleaning operations. Furthermore, the folding function of the foldable carbon tube 218 further enhances the portability and practicality of the device.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
