Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to an extension device for a drone cleaning nozzle. Background Technology

[0002] With the increasing technological sophistication of photovoltaic power plant operation and maintenance, drone operation and maintenance has become a major development direction, among which drone cleaning is one of the main directions of drone operation and maintenance development.

[0003] Because the distance between the drone's nozzle and the photovoltaic panel is too large during drone cleaning, or because the photovoltaic panel is tilted, the nozzle cannot effectively get close to clean, resulting in poor cleaning effect or almost no cleaning.

[0004] Therefore, how to provide a drone cleaning nozzle extension device to at least partially solve the above-mentioned drawbacks is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a drone cleaning nozzle extension device that allows the drone to maintain a safe flight distance during cleaning operations while bringing the cleaning end closer to the photovoltaic panel, thereby improving the efficiency and effectiveness of drone cleaning.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A drone cleaning nozzle extension device is installed on the drone's take-off and landing bracket. The take-off and landing bracket includes a left support leg, a right support leg, and a reinforcing crossbar connecting the two. The drone cleaning nozzle extension device also includes:

[0008] The tilting support includes two parallel telescopic extension rods and a support crossbar. One end of one of the two telescopic extension rods is rotatably connected to the left outrigger, and one end of the other is rotatably connected to the right outrigger. The support crossbar is mounted on the ends of the two telescopic extension rods opposite to the lifting support.

[0009] The telescopic water hose has one end connected to the water pump on the drone and the other end detachably connected to the support crossbar. When the water hose is not filled with water, it is in a retracted state to pull the flipping bracket to rotate toward the drone. When the water hose is filled with water, it is in an extended state to make the flipping bracket rotate away from the drone.

[0010] Preferably, the telescopic extension rod is connected to the left and right support legs respectively via a flip hinge. The flip hinge includes a first flip piece and a second flip piece. The first flip piece is hinged to the second flip piece. The first flip piece is connected to the left or right support leg, and the second flip piece is connected to the telescopic extension rod.

[0011] Preferably, the telescopic extension rod includes: a telescopic outer rod and a telescopic inner rod movably sleeved on the inner wall of the telescopic outer rod, wherein the telescopic inner rod is provided with an elastic limiting buckle connected to the telescopic outer rod, and the elastic limiting buckle is used to limit the sliding of the telescopic inner rod.

[0012] Preferably, the end of the telescopic outer rod that is away from the telescopic inner rod is detachably connected to the second flip plate by a detachable fixing bolt.

[0013] Preferably, the system also includes a water supply conversion box, which is detachably mounted on the reinforcing crossbar. The water supply conversion box is provided with a quick-release water pipe joint for connecting to a telescopic water pipe, and a water pipe connector for connecting to a water supply pump.

[0014] Preferably, a throttle valve is installed on the water supply conversion box, which is used to control the flow rate of water entering the telescopic water pipe.

[0015] Preferably, the cross section of the support crossbar is U-shaped, with a guide rail groove in the middle. The end of the telescopic water pipe away from the water supply pump is fixed to the support crossbar by a quick-release fixing buckle, which is movably installed in the guide rail groove.

[0016] Preferably, the end of the telescopic inner rod that faces away from the telescopic outer rod is connected to the support crossbar via a flexible fixing clamp.

[0017] Preferably, the water supply conversion box is fixedly installed on the reinforcing crossbar using a U-shaped fixing buckle.

[0018] Preferably, a quick-release nozzle is installed at the end of the telescopic water pipe away from the water supply pump.

[0019] Compared to the aforementioned background technology, the present invention provides a drone cleaning nozzle extension device, which is installed on the take-off and landing bracket of a drone. The take-off and landing bracket includes a left support leg and a right support leg that are parallel to each other, and a reinforcing crossbar connecting the two. The drone cleaning nozzle extension device also includes a flip-up bracket and a telescopic water pipe. The flip-up bracket includes two parallel telescopic extension rods and a supporting crossbar. One end of one of the two telescopic extension rods is rotatably connected to the left support leg, and one end of the other is rotatably connected to the right support leg. The supporting crossbar is mounted on the ends of the two telescopic extension rods that are away from the take-off and landing bracket. One end of the telescopic water pipe is connected to the water pump on the drone, and the other end is detachably connected to the supporting crossbar. The telescopic water pipe can be in a retracted state when it is not filled with water, so as to pull the flip-up bracket to rotate toward the drone. The telescopic water pipe can be in an extended state when it is filled with water, so as to make the flip-up bracket rotate away from the drone.

[0020] Specifically, the cleaning nozzle extension device is mounted on the drone's take-off and landing support, including a tilting bracket that can flip upwards and a retractable telescopic water hose. The two telescopic extension rods of the tilting bracket are rotatably connected to the left and right legs of the take-off and landing support, respectively. One end of the telescopic water hose is connected to a water pump mounted on the drone, and the other end is fixed to a support crossbar. In this embodiment, the cleaning nozzle extension device has two operating states. First, when the telescopic water hose is not filled with water, i.e., cleaning has not yet begun, the hose shortens due to the lack of water pressure and its own elasticity. Since one end is connected to the water pump on the drone... The other end is connected to the support crossbar, and the rotating bracket rotates with the drone, which pulls the support crossbar, causing the rotating bracket to rotate towards the drone, i.e., to rotate upwards. This ensures that the minimum height of the device is higher than the drone's take-off and landing bracket, guaranteeing the drone's flight safety. When the drone reaches its designated position, the water pump is turned on, and water flows into the telescopic water pipe. Due to the water pressure, the pipe extends, causing the rotating bracket to rotate the outlet of the telescopic water pipe downwards. This ensures that the drone flies at a safe altitude while bringing the outlet of the telescopic water pipe as close as possible to the photovoltaic panel, thus placing the outlet at the optimal cleaning height and improving cleaning efficiency and effectiveness.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0038] The purpose of this invention is to provide a drone cleaning nozzle extension device that allows the drone to maintain a safe flight distance during cleaning operations while bringing the cleaning end closer to the photovoltaic panel, thereby improving the efficiency and effectiveness of drone cleaning.

[0039] To achieve the above objectives, the present invention provides the following technical solution:

[0040] Please see Figures 1 to 2This embodiment provides a drone cleaning nozzle extension device, which is installed on the drone's take-off and landing bracket. The take-off and landing bracket includes a left support leg 01 and a right support leg 02 that are parallel to each other, and a reinforcing crossbar 03 connecting the two. The drone cleaning nozzle extension device also includes a flip-up bracket and a telescopic water pipe 3. The flip-up bracket includes two parallel telescopic extension rods 1 and a supporting crossbar 2. One end of one of the two telescopic extension rods 1 is rotatably connected to the left support leg 01, and one end of the other is rotatably connected to the right support leg 02. The supporting crossbar 2 is mounted on the ends of the two telescopic extension rods 1 that are away from the take-off and landing bracket. One end of the telescopic water pipe 3 is connected to a water pump 4 on the drone, and the other end is detachably connected to the supporting crossbar 2. The telescopic water pipe 3 can be in a retracted state when it is not filled with water, so as to pull the flip-up bracket to rotate toward the drone. The telescopic water pipe 3 can be in an extended state when it is filled with water, so as to make the flip-up bracket rotate away from the drone.

[0041] Specifically, such as Figure 1 As shown, the cleaning nozzle extension device is installed on the take-off and landing bracket of the drone, including a flip-up bracket that can be flipped upwards and a flexible telescopic water pipe 3 that can be extended or retracted. The flip-up bracket includes two telescopic extension rods 1 and a support crossbar 2, which together form a U-shaped frame with the open end of the frame facing the drone. Specifically, the two telescopic extension rods 1 are rotatably connected to the left support leg 01 and the right support leg 02 of the take-off and landing bracket, respectively, while the support crossbar 2 is connected to the ends of the two telescopic extension rods 1 that are away from the take-off and landing bracket. In this way, when the support crossbar 2 is subjected to an upward force, it will cause the entire flip-up bracket to flip upwards.

[0042] In this embodiment, the telescopic water pipe 3 is made of an elastic material with great elasticity. One end of the telescopic water pipe 3 is connected to the water pump 4 installed on the drone, and the other end is fixed to the support crossbar 2. That is, the water inlet end is connected to the water pump 4, and the water outlet end is connected to the support crossbar 2. It should be noted that in this embodiment, the telescopic water pipe 3 will pull the flipping bracket to the upward flipping state in its natural state. Only when it is in the extended state will it extend to make the flipping bracket flip downward.

[0043] Of course, the length and material of the telescopic water pipe 3 and the length of the telescopic extension rod 1 in this embodiment need to be adjusted according to the actual situation, such as the height of the take-off and landing bracket and the tilt angle of the photovoltaic panel surface. The length of both needs to ensure that the flip bracket can not only flip upward to above the take-off and landing bracket, but also ensure that when the drone is at a safe flight altitude, the flip bracket can flip downward to the optimal cleaning height from the photovoltaic panel surface. Therefore, this article does not make specific limitations on the original length of the telescopic water pipe 3, its material, and the length of the telescopic extension rod.

[0044] The cleaning nozzle extension device in this embodiment has two operating states. First, when the telescopic water pipe 3 is not filled with water, i.e., cleaning has not started, the telescopic water pipe 3 will shorten due to its own elasticity because there is no water pressure inside. Since one end is connected to the water pump 4 on the drone and the other end is connected to the support crossbar 2, and the flipping bracket rotates with the drone, it will pull the support crossbar 2, i.e., the flipping bracket will rotate towards the drone, i.e., flip upward. This ensures that the minimum height of the device is higher than the drone's take-off and landing bracket, ensuring the drone's flight safety. When the drone flies to the designated position, the water pump 4 is turned on, and water is filled into the telescopic water pipe 3. It will extend due to water pressure, causing the flipping bracket to flip the outlet of the telescopic water pipe 3 downward. This ensures that the drone flies at a safe altitude while bringing the outlet of the telescopic water pipe 3 as close as possible to the photovoltaic panel, so that the outlet of the telescopic water pipe 3 is at the optimal cleaning height, thus improving cleaning efficiency and effect.

[0045] Preferably, the telescopic extension rod 1 is connected to the left support leg 01 and the right support leg 02 respectively via a flip hinge 5. The flip hinge 5 includes a first flip piece 51 and a second flip piece 52. The first flip piece 51 and the second flip piece 52 are hinged together. The first flip piece 51 is connected to the left support leg 01 or the right support leg 02, and the second flip piece 52 is connected to the telescopic extension rod 1.

[0046] Specifically, such as Figure 1 As shown, in this embodiment, the rotation connection between the flipping bracket and the lifting bracket is achieved by setting a flipping hinge 5; specifically, the flipping hinge 5 includes a first flipping piece 51 and a second flipping piece 52 that are hinged to each other, the two telescopic extension rods 1 of the flipping bracket are installed on the second flipping piece 52, and the first flipping pieces 51 of the two flipping hinges 5 are respectively installed on the left support leg 01 and the right support leg 02.

[0047] It should be noted that in another embodiment, the flip hinge 5 has a limiting requirement to prevent the flip bracket from exceeding the preset range when rotating. Similarly, the flip hinge 5 can also be adjusted to different angles to adapt to the cleaning of photovoltaic panel surfaces at different tilt angles, ensuring that the descent angle of the support crossbar 2 meets the required nozzle cleaning angle, and ensuring that the photovoltaic panel can have the best cleaning effect.

[0048] Preferably, the telescopic extension rod 1 includes: a telescopic outer rod 11 and a telescopic inner rod 12 movably sleeved on the inner wall of the telescopic outer rod 11. The telescopic inner rod 12 is provided with an elastic limiting buckle 13 connected to the telescopic outer rod 11. The elastic limiting buckle 13 is used to limit the sliding of the telescopic inner rod 12.

[0049] Furthermore, to ensure that the telescopic water pipe 3 reaches the optimal cleaning height and outlet angle relative to photovoltaic panel surfaces at different tilt angles when the rotating bracket is flipped downwards, the telescopic extension rod 1 in this embodiment includes two relatively movable telescopic outer rods 11 and inner telescopic rods 12. The inner telescopic rod 12 passes through the inner wall of the outer telescopic rod 11, and an elastic limiting buckle 13 is provided at the end of the inner telescopic rod 12. At the same time, a corresponding groove is provided at the end of the outer telescopic rod 11. When both are adjusted to the appropriate position, the elastic limiting buckle 13 on the inner telescopic rod 12 can be precisely engaged in the groove at the end of the outer telescopic rod 11, thereby fixing the inner telescopic rod 12 and the outer telescopic rod 11. With this configuration, the operator can adjust the telescopic extension rod 1 according to the actual tilt angle of the photovoltaic panel, thereby ensuring that the outlet of the telescopic water pipe 3 is at the optimal cleaning height and angle, thus guaranteeing the cleaning effect and efficiency.

[0050] Preferably, the end of the telescopic outer rod 11 that is away from the telescopic inner rod 12 is detachably connected to the second flip piece 52 by a detachable fixing bolt 6.

[0051] Understandably, the detachable fixing bolt 6 can quickly connect or separate the telescopic outer rod 11 and the second flip plate 52. This design can improve the convenience of installation and maintenance for operators, and can also ensure that when the extension device collides with an object during the flight of the drone, the collision or pulling can quickly separate it from the drone, thus ensuring the flight safety of the drone.

[0052] Preferably, the system also includes a water supply conversion box 7, which is detachably mounted on the reinforcing crossbar 03. The water supply conversion box 7 is provided with a quick-release water pipe connector 71 for connecting to the telescopic water pipe 3, and a water pipe connector 72 for connecting to the water supply pump 4.

[0053] Specifically, such as Figure 1 and Figure 2 As shown, in this embodiment, in order to increase the cleaning area each time, multiple telescopic water pipes 3 are arranged in parallel. Therefore, in order to allow water to flow from these telescopic water pipes 3 simultaneously, a water supply conversion box 7 is fixedly connected to the reinforcing crossbar 03 of the drone. The box 7 has a cavity inside, and multiple quick-release water pipe connectors 71 are evenly and spaced apart on the side near the flipping bracket. At the same time, a water pipe connector 72 for connecting to the water supply pump 4 is provided on the opposite side. In this way, the water pump 4 pumps water into the water supply conversion box 7 and then distributes it to each telescopic water pipe 3. The appropriate number of quick-release water pipe connectors 71 can be set according to the actual cleaning area. This not only improves the cleaning efficiency and cleaning effect, but also makes it convenient for operators to install and disassemble the telescopic water pipes 3 and the water supply pump 4.

[0054] Of course, in another embodiment, in order to ensure sufficient water supply to the water supply conversion box 7, multiple water pipe connectors 72 can be provided on its rear side to connect multiple water supply pumps 4. In addition, the model of the water pipe connectors 72 provided on the water supply conversion box 7 can also be adjusted according to the actual water supply pumps 4.

[0055] Preferably, the water supply conversion box 7 is equipped with a throttle valve 73, which is used to control the flow rate of water entering the telescopic water pipe 3.

[0056] Furthermore, when multiple water supply pumps 4 are connected to the water supply conversion box 7, a throttle valve 73 corresponding to the number of water supply pumps 4 is also installed on the water supply conversion box 7 in order to open or close it according to the cleaning requirements. This arrangement allows the water pipe connector 72 to be connected to one pump or multiple pumps to one pump, so as to ensure that water supply pumps 4 of different models can be supplied with water through the water supply conversion box 7. This allows the water consumption to be adjusted while ensuring the cleaning effect, thereby improving the final cleaning efficiency.

[0057] Preferably, the cross section of the support crossbar 2 is U-shaped, with a guide rail groove 21 in the middle. The end of the telescopic water pipe 3 away from the water supply pump 4 is fixed to the support crossbar 2 by a quick-release fixing buckle 8, which is movably installed in the guide rail groove 21.

[0058] Understandably, by adjusting the position of the quick-release fixing buckle 8 on the U-shaped guide groove 21 of the support crossbar 2, and adjusting the distribution position of the water outlet of the telescopic water pipe 3, the cleaning requirements of the key cleaning areas of the photovoltaic panel can be guaranteed, and the cleaning effect can be increased.

[0059] Preferably, the end of the telescopic inner rod 12 that is away from the telescopic outer rod 11 is connected to the support crossbar 2 via a flexible fixing clamp 9.

[0060] Understandably, the soft fixing clamp 9, in addition to its function of fixing and supporting the crossbar 2, is made of relatively soft plastic, which can ensure that the photovoltaic panel will not be scratched when the drone flies too low or other accidents cause it to come into contact with the photovoltaic panel.

[0061] Preferably, the water supply conversion box 7 is fixedly installed on the reinforcing crossbar 03 by a U-shaped fixing buckle 10.

[0062] In this embodiment, the water supply conversion box 7 has a strip-shaped structure, and its two ends can be fixed to the reinforcing crossbar 03 by U-shaped fixing buckles 10. This connection method is simple and convenient, and the connection is stable and easy to install and remove.

[0063] Preferably, a quick-release nozzle 31 is installed at the end of the telescopic water pipe 3 that is away from the water supply pump 4.

[0064] Understandably, in order to improve the cleaning effect on photovoltaic panels, in this embodiment, a quick-release nozzle 31 is installed at the end of the telescopic water pipe 3, which can increase the pressure when the water is sprayed out, improve the utilization rate of the water flow, and improve the cleaning effect.

[0065] Furthermore, in this embodiment, the detachable fixing bolt 6, the quick-release water pipe connector, and the quick-release nozzle 31 are all designed to be detached quickly. In the event of a strong collision, or if the telescopic water pipe 3 gets stuck or pulled, the cleaning nozzle extension device can be quickly separated from the drone, ensuring the drone's flight safety.

[0066] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0067] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0068] The embodiments provided by this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
