Description

Technical Field

[0001] This utility model relates to the field of photovoltaic maintenance equipment technology, specifically a photovoltaic module cleaning device. Background Technology

[0002] Photovoltaic module cleaning equipment is a tool specifically designed for cleaning photovoltaic panels. Since photovoltaic panels are exposed to the outdoor environment, they easily accumulate dust, pollutants, bird droppings, etc., which affects their power generation efficiency. Therefore, it is very important to clean photovoltaic panels regularly. To meet this need, there are various types of photovoltaic module cleaning equipment on the market, covering both manual and automated cleaning equipment.

[0003] In existing technologies, some photovoltaic module cleaning equipment cleans the surface of photovoltaic panels by spraying water. However, the water flow rate of these devices is fixed, which often results in poor cleaning performance when dealing with stubborn stains such as bird droppings or other difficult-to-remove deposits. This is because the fixed water flow rate may not be sufficient to effectively dissolve or remove these stubborn stains. On the other hand, when cleaning minor contaminants such as dust, the cleaning equipment consumes too much water, resulting in water waste. Since the water flow rate cannot be adjusted according to the nature or degree of contamination of different stains, this fixed flow rate design makes the cleaning process inflexible and unable to provide the optimal water volume for different cleaning needs, reducing the applicability and cleaning efficiency of the equipment. Therefore, we propose a photovoltaic module cleaning device. Utility Model Content

[0004] The purpose of this invention is to provide a photovoltaic module cleaning device to solve the problems mentioned in the background art, which use a fixed flow rate of water to clean the surface of photovoltaic panels. The water flow rate cannot be adjusted according to the nature or degree of pollution of different stains, resulting in a lack of flexibility in use and reducing the applicability and cleaning efficiency of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic module cleaning device, including a cleaning rod, a mounting base rotatably connected to the bottom end of the cleaning rod, two sliding columns slidably connected inside the mounting base, a cleaning plate fixedly connected to the bottom end of the two sliding columns, a water outlet pipe fixedly connected to the top end of the mounting base, a water pump fixedly connected to the top end of the mounting base, the water outlet pipe connected to the water pump, a flexible hose fixedly connected to the top end of the water pump, a water outlet regulating mechanism for regulating the water flow of the water outlet pipe at the top end of the cleaning plate, and a start switch installed at the top end of the water pump.

[0006] The water outlet adjustment mechanism includes a fixed base fixedly connected to the top of the cleaning plate, a rotating column internally threaded onto the fixed base, and a connecting sleeve fixedly connected to the top of the rotating column.

[0007] The water pump has an adjustment groove on its front side, and an adjustment rod is slidably connected inside the adjustment groove. The outside of the adjustment rod is slidably connected inside the connecting sleeve.

[0008] Each of the two sliding columns is fitted with a push spring, and each of the two sliding columns is slidably connected to a push ring. The top ends of the two push springs are respectively fixedly connected to the bottom ends of the two push rings.

[0009] Each of the two sliding columns has an installation groove inside, and each of the two installation grooves has a stop block slidably connected inside.

[0010] Each of the two mounting slots is equipped with a push spring, and the top of each of the two stops is fixedly connected with a toggle lever. The outer sides of the two toggle levers are slidably connected to the inside of the two sliding columns.

[0011] The cleaning rod is fixedly connected to an anti-slip sleeve on its outer side, and multiple restraints are fixedly connected to the outer side of the cleaning rod. The hose is installed inside the multiple restraints.

[0012] This utility model has at least the following beneficial effects:

[0013] By controlling the sliding of the adjusting rod inside the adjusting groove, the power of the water pump can be adjusted, thereby controlling the flow rate of cleaning water from the outlet pipe.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figures 1 to 6 This utility model provides a technical solution: a photovoltaic module cleaning device, including a cleaning rod 1, which is a connector for connecting to a mounting base 2, allowing the user to hold the cleaning rod 1 and move the mounting base 2 and cleaning plate 4. The bottom end of the cleaning rod 1 is rotatably connected to the mounting base 2. The mounting base 2 is designed to facilitate the installation of the hose 7 and the cleaning plate 4. Two sliding posts 3 are slidably connected inside the mounting base 2. The sliding posts 3 are designed to facilitate connecting the mounting base 2 and the cleaning plate 4 together. The bottom ends of the two sliding posts 3 are fixedly connected to the cleaning plate 4, which is designed to clean the surface of the photovoltaic panel. The top end of the mounting base 2 is fixedly connected to the cleaning plate 4. A water outlet pipe 5 is fixedly connected to the top of the mounting base 2. The water outlet pipe 5 is designed to cooperate with the water pump 6 and the hose 7 to spray water to clean the surface of the photovoltaic panel. The water pump 6 is fixedly connected to the top of the mounting base 2. The function of the water pump 6 is to supply water to the water outlet pipe 5. The water outlet pipe 5 is connected to the water pump 6. The top of the water pump 6 is fixedly connected to the hose 7. When using the cleaning device, one end of the hose 7 needs to be connected to the water supply storage tank so that the water pump 6 can draw water. The top of the cleaning plate 4 is provided with a water outlet adjustment mechanism 8 for adjusting the water output of the water outlet pipe 5. The top of the water pump 6 is equipped with a start switch 9. The start switch 9 is designed to turn the water pump 6 on and off.

[0024] The water outlet adjustment mechanism 8 includes a fixed base 801 fixedly connected to the top of the cleaning plate 4. The fixed base 801 is designed to fix the rotating column 802 and connect the rotating column 802 to the cleaning plate 4. After the rotating column 802 is installed on the outside of the adjustment rod 805, the rotating column 802 is inserted into the interior of the fixed base 801, and the nut-like component inside the fixed base 801 is rotated to connect the fixed base 801 and the rotating column 802. The rotating column 802 is threadedly connected to the interior of the fixed base 801. The rotating column 802 can connect the fixed base 801 and the adjustment rod 805. A connecting sleeve 803 is fixedly connected to the top of the rotating column 802, and the connecting sleeve 803 allows the rotating column 802 to be connected to the adjustment rod 805.

[0025] The front side of the water pump 6 is provided with an adjustment groove 804, which facilitates the sliding of the adjustment rod 805. The adjustment rod 805 is slidably connected inside the adjustment groove 804. The adjustment rod 805 can adjust the power of the water pump 6 by sliding inside the adjustment groove 804. When the adjustment rod 805 is higher in the adjustment groove 804, the power of the water pump 6 is greater. When the adjustment rod 805 is at the lowest position in the adjustment groove 804, the power of the water pump 6 is the minimum. The outer side of the adjustment rod 805 is slidably connected to the inside of the connecting sleeve 803.

[0026] Push springs 806 are fitted on the outer sides of both sliding columns 3. The push springs 806 are designed to push the two push rings 807, thereby pushing the entire mounting base 2. Push rings 807 are slidably connected to the outer sides of both sliding columns 3. The tops of the two push springs 806 are fixedly connected to the bottoms of the two push rings 807. When cleaning dust from the photovoltaic panel surface is required, first connect the water storage device to the hose 7 to prepare for cleaning. After preparation, press the start switch 9. The start switch 9 will start the water pump 6, allowing the water pump 6 to cooperate with the hose 7 and the outlet pipe 5. At this time, the outlet pipe 5 will flow out water at a minimum flow rate, making it convenient for the user to clean the dust on the photovoltaic panel. When cleaning bird droppings and other attached dirt on the photovoltaic panel, the user needs to use the cleaning equipment more forcefully. Bird droppings and other attached dirt are removed. During this process, the mounting base 2 is pressed down, causing the water pump 6 to descend. This results in the adjusting rod 805, connected to the connecting sleeve 803, sliding upwards inside the adjusting groove 804. To a certain extent, the greater the force the user applies to the cleaning device, the greater the distance the mounting base 2 is pushed down, and the longer the adjusting rod 805 slides upwards inside the adjusting groove 804. The greater the power of the water pump 6, the greater the flow rate of cleaning water sprayed from the outlet pipe 5. By controlling the sliding of the adjusting rod 805 inside the adjusting groove 804, the power of the water pump 6 is adjusted, thereby controlling the flow rate of cleaning water from the outlet pipe 5. This allows the water flow rate to be adjusted according to the nature or degree of contamination, providing the optimal water volume for different cleaning needs. This makes the cleaning process more flexible and improves the applicability and cleaning efficiency of the equipment.

[0027] Example 2

[0028] In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that the two sliding columns 3 are provided with mounting grooves 10 inside. The mounting grooves 10 are designed to facilitate the installation of the stop block 11 and the push spring 12. The two mounting grooves 10 are slidably connected with the stop block 11 inside. The stop block 11 is designed to be pushed out by the push spring 12, thereby limiting the mounting seat 2 on the sliding column 3.

[0029] Both mounting slots 10 are equipped with push springs 12. The push springs 12 are designed to push the stop block 11 and limit the stop block 11 to the mounting seat 2. The top of each stop block 11 is fixedly connected with a toggle rod 13. The toggle rod 13 is designed to facilitate toggling the stop block 11. The outer sides of the two toggle rods 13 are slidably connected to the inside of the two sliding columns 3.

[0030] An anti-slip sleeve 14 is fixedly connected to the outside of the cleaning rod 1. The anti-slip sleeve 14 is designed to make it easier for the user to hold the cleaning rod 1. Multiple restraints 15 are fixedly connected to the outside of the cleaning rod 1. The restraints 15 are designed to restrain the hose 7. The hose 7 is located inside the multiple restraints 15.
