Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cleaning machines, specifically to a water-driven photovoltaic panel cleaning machine with long endurance. Background Technology

[0002] With the widespread application of photovoltaic power generation technology, the cleaning and maintenance of photovoltaic panels has become a crucial aspect of ensuring power generation efficiency. Currently, self-propelled photovoltaic cleaning machines are widely used in the daily cleaning work of photovoltaic power plants. These cleaning machines mostly adopt a structure of tracked vehicles with electrically driven sweeping rollers and water sprayers (such as the self-propelled photovoltaic cleaning machine disclosed in patent number CN119363014A), with all power derived from electricity. However, due to the limited carrying capacity of the tracked vehicles, the battery capacity is limited, resulting in insufficient range for the cleaning machines. In the cleaning work of large-area photovoltaic power plants, frequent charging or battery replacement is required, greatly affecting work efficiency and increasing operating costs. Utility Model Content

[0003] In view of the above, the purpose of this utility model is to address the problems of the prior art by providing a water-driven photovoltaic panel cleaning machine with long endurance.

[0004] This solution includes a water-driven, high-endurance photovoltaic panel cleaning machine, which includes a tracked vehicle with a platform on it. An adjustable bracket is fixed to the platform and used to install cleaning rollers.

[0005] The adjustable bracket includes a large-span mounting plate, with an impeller mounted on the top of each end of the large-span mounting plate and a right-angle reducer mounted on the bottom of each end of the large-span mounting plate. The shaft of the impeller is connected to the input end of the right-angle reducer, and the two ends of the cleaning roller are connected to the output shafts of the two right-angle reducers.

[0006] The large-span mounting plate is equipped with two water outlets, the spray direction of which is directly facing the impeller blades, and the water outlets are connected to an external high-pressure water source through pipelines;

[0007] The adjustable bracket is used to adjust the height of the cleaning roller to match the surface pressure of the photovoltaic panel.

[0008] Furthermore, the adjustable bracket has a triangular structure and includes a base rod parallel to the platform, an inclined rod inclined relative to the base rod, and a variable-length structure disposed between the inclined rod and the base rod.

[0009] The large-span mounting plate is provided with a connecting part above it. The connecting part has a first hinge point and a second hinge point. The front end of the bottom rod is connected to the connecting part through the first hinge point. The two ends of the variable length structure are respectively hinged to the top of the diagonal rod and the second hinge point of the connecting part.

[0010] Furthermore, the variable length structure includes a frame and two screws. The frame has internal threaded holes at both ends, with the threads of the two internal threaded holes in opposite directions. The two screws are screwed into the two internal threaded holes respectively, and the screws have lifting rings for hinge connection. By rotating the frame, the two screws move inward or outward synchronously to change the distance between the connecting part and the top of the inclined rod, thereby adjusting the tilt angle of the large-span mounting plate and the pressure of the cleaning roller on the photovoltaic panel.

[0011] Furthermore, the base rod is welded and fixed to the platform.

[0012] Furthermore, the base rod is provided with a first mounting hole and a second mounting hole, and the diagonal rod is fixed by two bolts passing through the diagonal rod and the first mounting hole and the second mounting hole.

[0013] Furthermore, the front end of the base rod is provided with a third mounting hole to match the first hinge point, and the connecting part is hinged by bolts inserted into the third mounting hole.

[0014] Furthermore, the platform is equipped with a support frame, on which a three-way connector is installed. An external high-pressure water source is connected to one end of the three-way connector, and the other two ends of the three-way connector are respectively connected to two water outlets.

[0015] Beneficial effects:

[0016] 1. This application adopts a water-driven method, which uses an external high-pressure water source to drive the impeller and drive the sweeping roller. No additional electricity is required to drive the sweeping roller, which significantly improves the endurance and effectively improves the work efficiency.

[0017] 2. This application eliminates the need for a water sprayer. The water flow from the impeller naturally flows onto the photovoltaic panel, working in conjunction with the cleaning roller to achieve a highly efficient cleaning mode that combines rinsing and sweeping. This simplifies the equipment structure while improving the cleaning effect, making it more efficient than traditional cleaning machines.

[0018] 3. The adjustable bracket of this application adopts a unique triangular structure and variable length structure. By adjusting the variable length structure, the tilt angle of the large-span installation plate can be flexibly adjusted, and the height of the cleaning roller and the pressure on the photovoltaic panel can be precisely controlled. It can adapt to photovoltaic panels with different surface conditions. Whether it is a conventional flat photovoltaic panel or a special photovoltaic panel with slope or unevenness, it can be closely attached to the surface for cleaning. Traditional cleaning machines are difficult to meet the diverse surface cleaning needs of photovoltaic panels.

[0019] 4. The adjustable length structure is easy to adjust, requiring only the rotation of the frame without the need for complex tools or specialized skills. Workers can quickly adjust it to meet different cleaning needs. Furthermore, the installation method of the base rod and diagonal rods facilitates assembly and subsequent maintenance adjustments, making the overall equipment operation and maintenance more convenient and reducing the difficulty of manual operation and maintenance costs.

Detailed Implementation

[0024] 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.

[0025] Reference Figures 1 to 3 The diagram illustrates a water-driven, high-endurance photovoltaic panel cleaning machine. The core components of this machine include a tracked vehicle 1, cleaning rollers 2, and an adjustable support frame 102. The tracked vehicle 1 serves as the basic carrier, with a stable platform 101 mounted on it, providing reliable support for the installation and operation of subsequent components. The adjustable support frame 102, fixed to the platform 101, is responsible for mounting the cleaning rollers 2 and is a crucial component for achieving efficient operation of the cleaning machine.

[0026] The adjustable bracket 102 is equipped with a large-span mounting plate 3. Impellers 4 are symmetrically mounted at the top of both ends of the large-span mounting plate 3, and right-angle reducers 5 are correspondingly mounted at the bottom. The shafts of the impellers 4 are connected to the input ends of the right-angle reducers 5, and the two ends of the sweeping roller 2 are connected to the output shafts of the two right-angle reducers 5, forming a continuous power transmission system. Two water outlets 6 are provided on the large-span mounting plate 3, with their spray direction facing the blades of the impellers 4. The water outlets 6 are connected to an external high-pressure water source through pipelines. When the high-pressure water jet is sprayed out from the water outlets 6, it impacts the blades of the impellers 4. The impellers 4 rotate under the impact force of the water flow, converting the kinetic energy of the water flow into mechanical energy, which is then transmitted to the sweeping roller 2 through the right-angle reducers 5, driving the sweeping roller 2 to perform rotational sweeping operations. This water-driven method eliminates the need for additional electric drive devices, which not only reduces equipment energy consumption but also significantly improves the cleaning machine's endurance. It also eliminates the need for a water sprayer, as the water flow impacting the impeller 4 can naturally flow onto the photovoltaic panel. During the cleaning process of the sweeping roller 2, the water flow and the sweeping roller 2 work together to achieve a highly efficient cleaning mode of rinsing and sweeping simultaneously, further improving the cleaning effect.

[0027] The adjustable support 102 adopts a unique triangular structure, consisting of a base rod 7 parallel to the platform 101, an inclined rod 8 tilted relative to the base rod 7, and a variable-length structure 9 located between the inclined rod 8 and the base rod 7. A connecting part 301 is provided above the large-span mounting plate 3, with a first hinge point 301a and a second hinge point 301b. The front end of the base rod 7 is flexibly connected to the connecting part 301 via the first hinge point 301a, and the two ends of the variable-length structure 9 are respectively hinged to the top of the inclined rod 8 and the second hinge point 301b of the connecting part 301. By adjusting the variable-length structure 9, the side length and angle of the triangle can be easily changed, thereby achieving flexible adjustment of the tilt angle of the large-span mounting plate 3, and thus precisely controlling the height of the cleaning roller 2 and the pressure on the photovoltaic panel. This design allows the cleaning machine to perfectly adapt to photovoltaic panels with different surface conditions. Whether it is a regular photovoltaic panel with a flat surface or a special photovoltaic panel with a certain slope or unevenness, it can ensure that the cleaning roller 2 is in close contact with the surface of the photovoltaic panel, effectively improving the applicability and cleaning effect of the cleaning machine.

[0028] Specifically, the variable-length structure 9 consists of a frame 901 and two screws 902. The frame 901 has internally threaded holes at both ends, with the threads in opposite directions. The two screws 902 are screwed into their corresponding internally threaded holes, and each screw 902 has a lifting ring at its end for hinged connection with the diagonal rod 8 and the connecting part 301. During actual adjustment, the operator only needs to rotate the frame 901; due to the opposite thread directions, the two screws 902 will move synchronously inward or outward, thus precisely changing the distance between the connecting part 301 and the top of the diagonal rod 8. This precise adjustment mechanism enables fine adjustment of the tilt angle of the large-span mounting plate 3 and the pressure of the cleaning roller 2 on the photovoltaic panel, ensuring that the cleaning roller 2 and the photovoltaic panel surface always maintain the most suitable contact pressure. Moreover, this adjustment method is extremely simple, requiring no complex tools or professional skills. Operators can quickly adjust according to different photovoltaic panel cleaning needs during actual operation, significantly improving work efficiency and reducing labor costs.

[0029] To enhance structural strength and prevent the front end of the cleaning machine from detaching, the base rod 7 is fixed to the platform 101 by welding, ensuring a strong connection between the base rod 7 and the platform 101, which can withstand various stresses and vibrations generated during the operation of the cleaning machine.

[0030] The base rod 7 has at least two mounting holes, namely the first mounting hole 701 and the second mounting hole 702, for mounting the diagonal rod 8. The diagonal rod 8 is fixed in place by two bolts passing through the diagonal rod 8 and the two mounting holes. This installation method facilitates assembly and makes subsequent maintenance and adjustment easier.

[0031] The front end of the base rod 7 is provided with a third mounting hole 703 to cooperate with the first hinge point 301a. The connecting part 301 is hinged by bolts inserted into the third mounting hole 703. This hinge method allows the connecting part 301 to rotate flexibly while ensuring the stability of the connection, which is beneficial for assembly and subsequent maintenance and adjustment.

[0032] To ensure overall balance, a bracket 102 is installed on the platform 101, and a T-connector 10 is mounted on the bracket 102. An external high-pressure water source is connected to one end of the T-connector 10, and the other two ends of the T-connector 10 are connected to two water outlets 6 respectively. When the pipeline connecting the external high-pressure water source is connected to the T-connector 10 on the platform 101, it creates a rearward pull and counterweight on the tracked vehicle 1. This pull and counterweight effect effectively enhances the balance of the tracked vehicle 1, making the cleaning machine more stable during travel and operation, and reducing malfunctions and safety hazards caused by imbalance.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
