Description

Technical Field

[0001] This utility model relates to the field of photovoltaic construction technology, and more specifically, to a photovoltaic panel cleaning device for photovoltaic construction. Background Technology

[0002] Photovoltaic construction refers to the process of installing and building a solar photovoltaic power generation system. To ensure power generation efficiency, the dust on the surface of the photovoltaic panels needs to be cleaned after installation.

[0003] Current photovoltaic panel cleaning devices generally consist of a telescopic rod and a cleaner rotatably mounted at one end of the rod. The cleaner has several nozzles installed on its surface. After the user supplies pressurized water into the cleaner, the water will spray out from the nozzles. When the user holds the cleaner to clean the photovoltaic panels, the water can play an auxiliary cleaning role. However, the water outlet positions on current cleaners are fixed. This means that during the cleaning process, some areas on the photovoltaic panel surface cannot be sprayed by the pressurized water and are only covered by the water flow, which reduces the cleaning effect.

[0004] Therefore, it is necessary to design a new type of photovoltaic panel cleaning device for photovoltaic construction to solve the above problems. Utility Model Content

[0005] In view of this, this utility model proposes a photovoltaic panel cleaning device for photovoltaic construction to solve the problem that the nozzles on the surface of existing photovoltaic panel cleaning devices cannot cover and impact the surface of the photovoltaic panel.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A photovoltaic panel cleaning device for photovoltaic construction includes a telescopic rod, a cleaning head mechanism, and a water supply mechanism. The cleaning head mechanism includes a connecting rod perpendicular to the telescopic rod and connected to the telescopic end of the telescopic rod at its middle position. A circular water inlet chamber is fixedly connected to each end of the connecting rod. A rotating chamber is correspondingly and rotatably connected below each water inlet chamber. The rotating chambers and the water inlet chambers together form a water storage chamber. Several pressurized water nozzles are evenly distributed around the sidewalls of the rotating chambers, and a cleaning brush is installed on the outer bottom of the rotating chamber. A through hole is opened in the middle of the upper surface of the water inlet chamber. A driving rod extends from top to bottom through the through hole into the water storage chamber and is fixedly connected to the inner bottom surface of the rotating chamber. The driving rod is driven to rotate by a motor installed on the upper surface of the water inlet chamber. The water supply mechanism includes a main water pipe installed on the telescopic rod. One end of the main water pipe is connected to an external water pipe, and the other end is connected to two branch pipes. The two branch pipes are respectively connected to the water injection holes on the two water inlet chambers.

[0008] Preferably, the telescopic rod includes a main rod and a secondary rod. A portion of the secondary rod is slidably inserted into the main rod. A fixed threaded tube is fixedly fitted onto the telescopic end of the main rod. A plurality of plastic sheets are fixedly wrapped around one end of the fixed threaded tube extending beyond the main rod. An adjusting threaded tube is threadedly fitted onto the outside of the fixed threaded tube. The inner wall of the adjusting threaded tube away from the fixed threaded tube is provided with a contact groove that can compress the corresponding plastic sheet. The rotation of the adjusting threaded tube causes the contact groove to move towards the telescopic end of the main rod, compressing the plastic sheet and causing it to deform and shrink, thereby locking the secondary rod onto the main rod.

[0009] Preferably, the main water pipe is arranged parallel to the main rod, and the main water pipe is fixed to the main rod by several limiting seats.

[0010] Preferably, the telescopic end of the telescopic rod is fixed with a rotating groove that faces the connecting rod. A fixed rod parallel to the connecting rod is fixed in the rotating groove. A rotating plate is vertically mounted on the connecting rod. The end of the rotating plate away from the connecting rod is rotatably sleeved on the fixed rod. A torsion spring is provided on each side of the rotating plate. The two ends of the torsion spring are respectively fixed to the inner side wall of the rotating groove and the outer wall of the corresponding side of the rotating plate. At the same time, both torsion springs are looped around the fixed rod.

[0011] Preferably, the rotating chamber and the water inlet chamber are connected in a sealed rotating manner.

[0012] Preferably, the bottom of the rotating chamber is provided with a radially outward mounting protrusion, and the upper part of the cleaning brush is provided with a mounting plate. Bolt holes are provided at corresponding positions of the mounting protrusion and the mounting plate. The cleaning brush is connected to the rotating chamber by mounting bolts that pass through the upper and lower bolt holes.

[0013] Preferably, a transmission wheel is fixedly connected to the top of each of the two drive rods located on both sides of the connecting rod, and a belt is sleeved between the two transmission wheels; the transmission wheel on one of the drive rods is connected to the output end of the motor installed on the upper surface of the corresponding water inlet chamber.

[0014] Preferably, the inner wall of the end of the main water pipe is provided with a threaded groove for connection with an external water pipe, and the branch pipe is a corrugated pipe.

[0015] Preferably, a handle suspension component is installed on the telescopic rod.

[0016] Compared with existing technologies, the photovoltaic panel cleaning device for photovoltaic construction of this utility model has the following features:

[0017] Beneficial effects:

[0018] 1. This photovoltaic panel cleaning device for photovoltaic construction incorporates a handheld telescopic rod. When cleaning the photovoltaic panels, the user simply holds the rod, attaches the two cleaning brushes on one end of the rod to the surface of the photovoltaic panel, and then supplies water to the water storage tank via an external water supply pipe. Water is then sprayed from pressurized nozzles to clean the photovoltaic panels. Simultaneously, during cleaning, the user can control a motor to drive two rotating chambers, which in turn rotates several pressurized nozzles on the side walls of the rotating chambers, expanding the impact range of the water flow. This ensures that the surface of the photovoltaic panels near both rotating chambers is impacted by the water flow, effectively improving the cleaning effect. Furthermore, the rotation of the rotating chambers also drives the cleaning brushes to rotate, allowing for better cleaning of the photovoltaic panel surface.

[0019] 2. The photovoltaic panel cleaning device for photovoltaic construction can adjust the length of the telescopic rod on the device as needed, so that users do not need to stand on tiptoe to reach high places or bend over to reach low places, thus improving the comfort of cleaning.

[0020] 3. The photovoltaic panel cleaning device for photovoltaic construction is rotatably connected to the telescopic rod and the connecting rod, and is equipped with a corresponding torsion spring, which makes it easy for users to apply downward pressure to the photovoltaic panel with the two cleaning brushes, which helps to better clean the surface of the photovoltaic panel.

[0021] 4. The cleaning brush on the photovoltaic panel cleaning device used for photovoltaic construction can be disassembled and replaced, which helps to save costs. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] Example:

[0033] See Figure 1-Figure 5This embodiment provides a photovoltaic panel cleaning device for photovoltaic construction, including a telescopic rod 1, a cleaning head mechanism 2, and a water supply mechanism 3. The cleaning head mechanism 2 includes a connecting rod 4 perpendicular to the telescopic rod 1 and connected to the telescopic end of the telescopic rod 1 at its middle position. A circular water inlet chamber 5 is fixedly connected to each end of the connecting rod 4. A rotating chamber 6 is correspondingly and rotatably connected below each water inlet chamber 5. The rotating chamber 6 and the water inlet chamber 5 together form a water storage chamber. Several pressurized water nozzles 7 are evenly distributed around the side wall of the rotating chamber 6, and a cleaning nozzle is installed on the outer bottom of the rotating chamber 6. Brush 8; A through hole is opened in the middle of the upper end face of the water inlet chamber 5. A drive rod 9 extends from top to bottom through the through hole into the water storage chamber and is fixedly connected to the inner bottom surface of the rotating chamber 6. The drive rod 9 is driven to rotate by a motor 10 installed on the upper end face of the water inlet chamber 5. The button for controlling the start and stop of the motor 10 is installed on the hand grip of the telescopic rod 1. The water supply mechanism 3 includes a main water pipe 11 installed on the telescopic rod 1. One end of the main water pipe 11 is connected to an external water pipe, and the other end is connected to two branch pipes 12. The two branch pipes 12 are respectively connected to the water injection holes on the two water inlet chambers 5.

[0034] When using this utility model device, the user drives two drive rods 9 to rotate via motor 10, which in turn drives two rotating chambers 6 to rotate. Water is supplied to the two water storage chambers via an external water pipe connected to the water supply mechanism 3. The water flow is sprayed out through several pressurized water nozzles 7 evenly distributed around the side wall of the rotating chamber, thus rinsing the photovoltaic panels. Because the rotating chamber 6 is in a rotating state, the impact range of the water sprayed by the pressurized water nozzles 7 is larger than that of the prior art, resulting in a better cleaning effect. Furthermore, because a cleaning brush 8 is provided below the rotating chamber 6, the cleaning brush 8 also rotates synchronously, thus wiping the surface of the photovoltaic panels.

[0035] In a further specific embodiment, such as Figure 2 As shown, the telescopic rod 1 includes a main rod 13 and a secondary rod 14. A portion of the secondary rod 14 is slidably inserted into the main rod 13. A fixed threaded tube 15 is fixedly fitted on the outside of the telescopic port end of the main rod 13. Several plastic sheets 16 are fixedly wrapped around the end of the fixed threaded tube 15 that extends beyond the main rod 13. An adjusting threaded tube 17 is fitted with an external threaded adapter. The inner wall of the adjusting threaded tube 17 away from the fixed threaded tube is provided with a contact groove 18 that can compress the corresponding plastic sheet 16. When the adjusting threaded tube 17 rotates, it drives the contact groove 18 to move closer to the telescopic port end of the main rod, compressing the plastic sheet 16 and causing the plastic sheet 16 to deform and shrink, clamping the secondary rod 14 and locking the secondary rod 14 onto the main rod 13.

[0036] In use, the user first adjusts the position of the auxiliary rod 14 inside the main rod 13, and then locks the auxiliary rod 14 onto the main rod 13 by rotating the adjusting threaded tube 17. This allows the user to adjust the total length of the main rod 13 and the auxiliary rod 14, thereby enabling the cleaning of photovoltaic panel surfaces at different heights.

[0037] Furthermore, the main water pipe 11 is arranged parallel to the main rod 13, and the main water pipe 11 is fixed to the main rod 13 by several limiting seats 19.

[0038] At the same time, such as Figure 3 As shown, the telescopic end of the telescopic rod 1 is fixed with a rotating groove 20 that faces the connecting rod 4. A fixed rod 21 parallel to the connecting rod 4 is fixed inside the rotating groove 20. A rotating plate 22 is vertically installed on the connecting rod 4. The end of the rotating plate 22 away from the connecting rod 4 is rotatably sleeved on the fixed rod 21. A torsion spring 23 is provided on each side of the rotating plate 22. The two ends of the torsion spring 23 are respectively fixed to the inner side wall of the rotating groove 20 and the outer wall of the corresponding rotating plate 22. At the same time, both torsion springs 23 are looped around the fixed rod 21.

[0039] When the user holds the main rod 13 and presses the cleaning head mechanism 2 down onto the surface of the photovoltaic panel, the two torsion springs 23 will be twisted, which makes it easier to apply a force to the two cleaning brushes 8 to press down on the photovoltaic panel. When the user lifts the main rod 13, the cleaning head mechanism 2 will spring back to its original position under the action of the rebound force of the two torsion springs.

[0040] In this invention, the rotating chamber 6 and the water inlet chamber 5 are connected by a sealed rotating connection to avoid water leakage.

[0041] In a further specific embodiment, the bottom of the rotating chamber 6 is provided with radially outward mounting protrusions 24, and the upper part of the cleaning brush 8 is provided with a mounting plate 25. Bolt holes are provided at corresponding positions on the mounting protrusions 24 and the mounting plate 25. The cleaning brush 8 is connected to the rotating chamber 6 by mounting bolts 26 passing through the upper and lower bolt holes. This utility model realizes the installation and removal of the cleaning brush 8 at the bottom of the rotating chamber 6 through the above structure, thereby allowing the cleaning brush 8 to be replaced, ensuring the cleaning effect of the device and saving costs.

[0042] In a further specific embodiment, a transmission wheel 27 is fixedly connected to the top of each of the two drive rods 9 located on both sides of the connecting rod 4, and a belt 28 is connected between the two transmission wheels 27; the transmission wheel 27 on one of the drive rods 9 is connected to the output end of the motor 10 installed on the upper surface of the corresponding water inlet chamber, and the motor 10 drives the two rotating chambers 6 to rotate simultaneously.

[0043] In this invention, the inner wall of the end of the main water pipe 11 is provided with a threaded groove for connection with an external water pipe. The branch pipe 12 is a corrugated pipe to allow the cleaning head mechanism 2 to rotate freely and the telescopic rod 1 to adjust its length freely.

[0044] In this utility model, a handle suspension component 29 is also installed on the telescopic rod 1, which can save storage space for the device to a certain extent and does not take up space.

[0045] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.
