Description

Technical Field

[0001] This utility model relates to the field of power equipment auxiliary technology, and in particular to a drone washing device. Background Technology

[0002] For the power industry, most of the monitoring equipment currently installed on transmission towers is equipped with solar panels. After long-term operation, dust will generally accumulate, leading to a decrease in power generation efficiency. Regular cleaning is required to improve the power generation efficiency of the solar panels and ensure the normal operation of the monitoring equipment. Previously, cleaning the solar panels required manpower to climb up the transmission tower with clean water and then use a wet roller or mop to clean them, which was time-consuming and labor-intensive.

[0003] To address this, existing technologies disclose washing devices that incorporate drones. The drone flies above the object to be cleaned, and the washing device is then remotely controlled to start rinsing. The water supply for these drone washing devices typically falls into two categories: those connected to the ground via water pipes and those with their own water tanks. The ground-connected water pipe type has limited flight altitude and is unsuitable for power equipment such as transmission towers that are hundreds of meters high. The self-contained water tank type is more suitable for power equipment on transmission towers. However, some existing technologies use only one container to hold a single cleaning liquid, which is insufficient for effectively cleaning power equipment. Other existing technologies use multiple containers to hold different cleaning liquids, each requiring an independent pumping system, resulting in excessive weight and complex structure for the entire drone.

[0016] In one embodiment, the thickness of the second piston is greater than the thickness of the first piston along the axial direction of the liquid storage container.

[0017] In one embodiment, the liquid storage container includes a wide-diameter section with the bottom opening, a variable-diameter section, and a narrow-diameter section with the connecting port, which are connected in sequence.

[0018] Both the first piston and the second piston are disposed within the wide diameter section, and the diameter of the wide diameter section is larger than the diameter of the narrow diameter section;

[0019] Along the direction from the wide diameter section to the narrow diameter section, the diameter of the variable diameter section gradually decreases.

A first piston slides and seals inside the liquid storage container, dividing the container into a first receiving chamber and a second receiving chamber. A one-way valve connects the first and second receiving chambers, allowing liquid in the second receiving chamber to flow unidirectionally into the first receiving chamber. Therefore, when the pump draws liquid, it extracts the first liquid from the first receiving chamber to the spray nozzle, which sprays the first liquid for the first round of cleaning.

Detailed Implementation

[0040] This utility model provides a drone washing device to solve the problems of redundant structure and insufficient cleaning ability in the prior art.

[0041] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0042] Please see Figures 1 to 3 The present invention provides a drone washing device, comprising a drone 1 and a washing mechanism 2 disposed on the drone 1;

[0043] The flushing mechanism 2 includes a first piston 20, a liquid storage container 21, a one-way valve 22, a liquid spraying component 23, and a liquid pump;

[0044] The first piston 20 is disposed inside the liquid storage container 21. The outer peripheral surface of the first piston 20 is slidably connected to the outer peripheral surface of the liquid storage container 21. The first piston 20 divides the interior of the liquid storage container 21 into a first receiving cavity 210 and a second receiving cavity 211.

[0045] A one-way valve 22 is installed on the first piston 20. The one-way valve 22 is used to allow the liquid in the second receiving chamber 211 to flow unidirectionally into the first receiving chamber 210.

[0046] The spray nozzle 23 is connected to the first receiving cavity 210;

[0047] A liquid pump is connected between the liquid spraying component 23 and the first receiving cavity 210. The liquid pump is used to pump the liquid in the first receiving cavity 210 or the liquid in the second receiving cavity 211 to the liquid spraying component 23.

[0048] It should be noted that the sealed sliding connection between the first piston 20 and the liquid storage container 21 is common knowledge. For example, the outer wall of the first piston 20 is fitted with a sealing ring to seal the sliding, and no further restrictions are imposed here. The liquid storage container 21 is also provided with two liquid filling ports, which are respectively arranged on the walls of the two receiving cavities. Liquid filling ports are fitted with liquid caps to seal the filling ports. The two liquid filling ports are used to add liquid to the first receiving cavity 210 and the second receiving cavity 211, respectively. The liquid pump is connected to the terminal signal through the electrical control box 25, and the terminal can remotely control the start and stop of the liquid pump. The drone 1 is common knowledge. Any drone 1 that can take off and land can be used as the drone 1 in this embodiment, and no further restrictions are imposed here.

[0049] In the operation of this embodiment, the user flies the drone 1 above the item to be cleaned, and then starts the liquid pump. The liquid pump draws the first liquid from the first receiving chamber 210 to the spraying component 23. The spraying component 23 sprays the first liquid and performs the first round of cleaning on the item to be cleaned. As the first liquid is drawn out, the hydraulic pressure in the first receiving chamber 210 is less than the hydraulic pressure in the second receiving chamber 211. The second liquid in the second receiving chamber 211 pushes the first piston 20 to move. Until the first piston 20 can no longer move, at this time, the second liquid in the second receiving chamber 211 flows from the one-way valve 22 into the first receiving chamber 210 and is drawn to the spraying component 23. The spraying component 23 sprays the second liquid and performs the second round of cleaning on the item to be cleaned.

[0050] It is understood that the first liquid can be a special cleaning solution and the second liquid can be water; or the first liquid can be water and the second liquid can be a protective solution. Those skilled in the art can reasonably choose the type of the first and second liquids according to their own needs. The part to be cleaned can be a solar panel or an insulator, etc., and those skilled in the art can reasonably choose according to their own needs.

[0051] As can be seen from the above working process, the first receiving chamber 210 and the second receiving chamber 211 are connected by a one-way valve 22. The first liquid in the first receiving chamber 210 cannot flow into the second receiving chamber 211. The second liquid in the second receiving chamber 211 will flow into the first receiving chamber 210 through the one-way valve 22 when the first piston 20 cannot be pushed. This structure can realize the containment of multiple solutions in the same container without the need for multiple sets of liquid pumping systems, and the structure is simple. Furthermore, the first and second liquids are used to clean the parts to be cleaned in multiple rounds, resulting in a better cleaning effect.

[0052] Compared with the prior art, the advantages of this embodiment are: First, the structure is simple. This embodiment can independently contain multiple solutions in the same container by cooperating with the first piston 20 in the liquid storage container 21 and the one-way valve 22. Moreover, when extracting the solution, there is no need for multiple extraction systems, which reduces the redundant extraction structure of the prior art. Second, the cleaning effect is good. This embodiment can use different liquids to perform multiple rounds of cleaning on the parts to be cleaned, resulting in a good cleaning effect.

[0053] In one specific embodiment, such as Figure 3 As shown, to improve the unidirectional flow efficiency of the second liquid, the flushing mechanism 2 further includes a second piston 24; the liquid storage container 21 has a communication port 212 and a bottom opening 213 at both axial ends, which communicate with the first receiving cavity 210. The communication port 212 is used for the installation of the spraying component 23 so that the communication port 212 communicates with the spraying component 23; along the direction from the communication port 212 to the bottom opening 213, the first piston 20 and the second piston 24 are arranged coaxially in sequence in the liquid storage container 21, and the outer peripheral surface of the second piston 24 is slidably connected to the inner peripheral surface of the liquid storage container 21; the first piston 20, the inner wall of the liquid storage container 21, and the end wall of the liquid storage container 21 with the communication port 212 enclose and form the first receiving cavity 210; the second piston 24 is arranged at intervals from the first piston 20 so that the second piston 24, the inner wall of the liquid storage container 21, and the first piston 20 enclose and form the first receiving cavity 210. The two pistons combine to form a second receiving cavity 211. In specific implementation, as before, when the pump draws the first liquid out of the first receiving cavity 210, the first piston 20 will push the first receiving cavity 210 to become smaller. Since one side of the second piston 24 is connected to the outside, when the hydraulic pressure in the first receiving cavity 210 decreases, the external air pressure will push the second piston 24 to move towards the first piston 20. When the first receiving cavity 210 still contains the first liquid, the first piston 20 and the second piston 24 move synchronously. When the first receiving cavity 210 does not contain the first liquid, the first piston 20 cannot continue to move, and the second piston 24 continues to move, thereby pushing the second liquid in the second receiving cavity 211 to flow into the first receiving cavity 210 from the one-way valve 22. Therefore, the second piston 24, in conjunction with the bottom opening 213, can effectively improve the one-way flow efficiency of the second liquid.

[0054] The outer wall of the connecting port 212 may be provided with threads, and the spraying component 23 may be provided with a corresponding threaded mounting port. The spraying component 23 is fixed to the liquid storage container 21 through the threaded mounting port and the connecting port 212 to realize the connection between the spraying component 23 and the first receiving cavity 210.

[0055] In one embodiment, such as Figure 3 As shown, in order to reduce the response time of the first piston 20 and maintain the rigidity of the second piston 24, the thickness of the second piston 24 is greater than the thickness of the first piston 20 along the axial direction of the liquid storage container 21. In specific implementation, the first piston 20 is thinner, making it easier for the hydraulic differential to push the first piston 20 and reducing the response time of the first piston 20; while the second piston 24 is thicker, and the second piston 24 is directly connected to the outside through the bottom opening 213, so the second piston 24 maintains its rigidity better.

[0056] In one embodiment, such as Figure 3 As shown, in order to improve the liquid flow efficiency, a feasible structure for the liquid storage container 21 is further provided. The liquid storage container 21 includes a wide-diameter section 214 with a bottom opening 213, a variable-diameter section 215, and a narrow-diameter section 216 with a connecting port 212, which are connected in sequence. The wide-diameter section 214, the variable-diameter section 215, and the narrow-diameter section 216 are cylindrical structures. The first piston 20 and the second piston 24 are both disposed in the wide-diameter section 214. That is, the first piston 20 is sealed and slidably connected to the wide-diameter section 214, and the second piston 24 is sealed and slidably connected to the wide-diameter section 214. The diameter of the wide-diameter section 214 is larger than the diameter of the narrow-diameter section 216. Along the direction from the wide-diameter section 214 to the narrow-diameter section 216, the diameter of the variable-diameter section 215 gradually decreases. In specific implementation, when the liquid enters the narrow-diameter section 216 from the wide-diameter section 214, the cross-section of the fluid channel becomes smaller and the flow velocity becomes faster, thereby improving the liquid flow efficiency.

[0057] In one embodiment, to further improve the liquid flow efficiency of the second receiving cavity 211, a feasible structure between the one-way valve 22 and the first piston 20 is provided. The first piston 20 is provided with a one-way through hole, which is coaxially arranged with the connecting port 212. The one-way valve 22 is installed in the one-way through hole, that is, the one-way valve 22 is coaxially arranged with the connecting port 212. In specific implementation, when the second liquid in the second receiving cavity 211 flows out from the one-way valve 22, the second liquid can flow directly along the axis into the connecting port 212, reducing the liquid flow trajectory and further improving the liquid flow efficiency.

[0058] In one specific embodiment, such as Figure 1 and Figure 2As shown, in order to adjust the spray angle of the spraying mechanism, the drone rinsing device also includes a rotating mechanism 3. The rotating mechanism 3 includes a fixed frame 30 and a rotating drive 31. The fixed frame 30 is fixedly installed at the bottom of the drone 1. The rotating drive 31 is fixedly installed at the bottom of the fixed frame 30. The output shaft of the rotating drive 31 is connected to the spraying component 23. The rotating drive 31 is used to rotate and adjust the spray angle of the spraying component 23. In specific implementation, the user starts the rotating drive 31, and the rotating drive 31 drives the spraying component 23 to rotate, thereby adjusting the spray angle of the liquid sprayed by the spraying component 23.

[0059] In one embodiment, such as Figure 2 As shown, the mounting frame 30 includes two drone frames 300 and two motor mounting plates 301; both drone frames 300 are connected to the bottom of the drone 1, the two drone frames 300 are arranged at intervals, and two oppositely arranged motor mounting plates 301 are fixed between the two drone frames 300. Rotation drive components 31 are fixed on the two motor mounting plates 301, and the output shaft of the rotation drive component 31 passes through the gap between the two motor mounting plates 301 and is connected to the spray component 23.

[0060] In this embodiment, as Figure 2 As shown, the mounting bracket 30 also includes a clamping plate 302 and a tensioning screw 303. The clamping plate 302 is located at the bottom of the spraying component 23. The clamping plate 302 is screwed to the mounting plate 304 by the tensioning screw 303, thereby fixing the entire spraying component 23 on the mounting bracket 30.

[0061] In one embodiment, the rotation drive 31 includes a rotation controller and a rotation motor; the rotation controller is electrically connected to the rotation motor and is used to control the start and stop of the rotation motor. The rotation motor is a DC geared motor. In a specific implementation, the user sends a control signal to the rotation controller through a terminal. After receiving the control signal, the rotation controller starts the rotation motor to rotate and output, thereby adjusting the spray angle of the spraying component 23.

[0062] In one embodiment, such as Figure 1 and Figure 2 As shown, in order to reduce the waste of spraying liquid from the spraying component 23, the spraying direction of the spraying component 23 is tilted downwards. In specific implementation, the downward tilting spraying component 23 can make the sprayed liquid reach the part to be cleaned more quickly, thereby reducing the waste of spraying liquid from the spraying component 23.

[0063] In this embodiment, as Figure 2 As shown, the rotating mechanism 3 also includes a rotating shaft 32; the rotating shaft 32 has a first end and a second end; the first end is fixedly connected to the output shaft of the rotating drive 31; the end face of the second end is an inclined surface, and the spraying component 23 is fixed on the inclined surface by the mounting plate 304 so that the spraying direction of the spraying component 23 is inclined downward.

[0064] In one embodiment, such as Figure 1 and Figure 2 As shown, in order to make full use of the space of the drone 1, the liquid storage container 21 is fixedly installed at the bottom of the spraying component 23. Therefore, the liquid storage container 21 can utilize the space below the drone 1, thereby improving the structural compactness of the device.

[0065] In one specific embodiment, a feasible structure for the spraying component 23 is further provided. The spraying component 23 is a high-pressure water gun component, which integrates a liquid pump. The internal structure of the high-pressure water gun component can be found in the prior art, and no further limitations are imposed here.
