Description

Technical Field

[0001] This invention belongs to the field of photovoltaic cleaning, and particularly relates to a temperature control device and a photovoltaic cleaning robot charging station. Background Technology

[0002] In photovoltaic power plants, dust and stubborn stains on the surface of photovoltaic panels seriously affect power generation efficiency. Therefore, various photovoltaic cleaning robots are produced for cleaning photovoltaic panels.

[0003] However, after a period of use, especially during hot weather, photovoltaic cleaning robots are prone to overheating, which requires them to stop for extended periods to cool down, thus affecting their efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a temperature control device and a photovoltaic cleaning robot charging station to solve the problem that photovoltaic cleaning robots need to stop for extended periods to dissipate heat.

[0005] To address the aforementioned problems, the present invention provides a temperature control device, comprising: The charging room can accommodate the photovoltaic cleaning robot and charge it. The charging room has an entrance and exit for the photovoltaic cleaning robot to enter and exit, and a spraying operation position is provided at the entrance and exit. The temperature control component includes a liquid supply structure for supplying liquid and a spray structure connected to the liquid supply structure, the spray structure being able to obtain liquid from the liquid supply structure and spray liquid onto the spray work station.

[0006] Optionally, the spray structure includes at least one water distribution pipe and a water pump. Each of the water distribution pipes is arranged above the spray operation position and has at least one downward-facing spray nozzle. The water pump can obtain liquid from the liquid supply structure and pump the liquid to each of the spray pipes.

[0007] Optionally, the spray nozzle may be detachably connected to a spray nozzle or a plug.

[0008] Optionally, at least two water distribution pipes are provided; Each of the aforementioned water distribution pipes is equipped with a first solenoid valve at its inlet.

[0009] Optionally, the liquid supply structure includes a water storage tank and a heating module for heating the water storage tank.

[0010] Optionally, the water storage tank is equipped with a liquid level detection component, which includes a high-level liquid level sensor and a low-level liquid level sensor that are arranged vertically and located at preset positions.

[0011] Optionally, the liquid supply structure further includes a water inlet pipe connected to the water storage tank and a second solenoid valve disposed on the water inlet pipe.

[0012] Optionally, the liquid supply structure further includes a filter disposed in the water inlet pipe; The second solenoid valve is located between the filter and the water storage tank.

[0013] Optionally, the charging chamber includes a wireless charging component for wirelessly charging the photovoltaic cleaning robot.

[0014] The present invention also provides a charging station for a cleaning robot, including the temperature control device described above.

[0015] Based on the structural design of this invention, after the photovoltaic cleaning robot has been used for a period of time, especially during hot weather when the photovoltaic cleaning robot needs to dissipate heat quickly, the photovoltaic cleaning robot can move to the spraying work position. The spraying structure can obtain liquid from the liquid supply structure and spray the liquid onto the spraying work position. After the liquid comes into contact with the photovoltaic cleaning robot, it can absorb heat from the photovoltaic cleaning robot, thereby quickly reducing the temperature of the photovoltaic cleaning robot and avoiding overheating damage. This allows the photovoltaic cleaning robot to not stop for a long time to dissipate heat, thus ensuring the continuity of cleaning tasks and improving the efficiency of the photovoltaic cleaning robot.

[0016] Furthermore, the spray structure can remove dust and other deposits from the photovoltaic cleaning robot during the spraying process, preventing excessive dust buildup that could reduce heat dissipation efficiency and ensuring optimal cooling during use. Moreover, the spray structure features both low-speed and high-speed spraying modes. In high-speed mode, the amount of liquid sprayed per unit time is greater than in low-speed mode. Therefore, when only cooling is needed, the low-speed spraying mode can be used to avoid liquid waste. Conversely, when both cooling and cleaning are required, the high-speed spraying mode can be used, utilizing the high-speed impact of the liquid to dislodge dust and other deposits.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0021] This invention provides a temperature control device. Although the temperature control device acts on a photovoltaic cleaning robot, it is not a part of the photovoltaic cleaning robot's structure. Please see Figures 1 to 4 The present invention includes a charging chamber 100 and a temperature control component 200.

[0022] Specifically, the charging chamber 100 can accommodate and charge the photovoltaic cleaning robot 300. By accommodating and charging the photovoltaic cleaning robot 300, the photovoltaic cleaning robot 300 can continuously perform photovoltaic cleaning operations. The charging chamber 100 is equipped with relevant charging devices for charging the photovoltaic cleaning robot 300, and the charging chamber 100 itself provides protection for the charging devices, such as preventing them from getting wet from rain or being exposed to direct sunlight. The charging chamber 100 has an entrance and exit 101 for the photovoltaic cleaning robot 300 to enter and exit. The photovoltaic cleaning robot 300 enters and exits through the entrance and exit 101 using its automatic driving function, without the need for manual intervention. A spraying station 102 is provided at the entrance / exit 101. The photovoltaic cleaning robot 300 will pass through the spraying station 102 when entering and exiting the charging chamber 100. The spraying station 102 can be located entirely outside the charging chamber 100, inside the charging chamber 100, or partly outside the charging chamber 100 and partly inside the charging chamber 100. In this embodiment, the spraying station 102 is located outside the charging chamber 100. The ground of the spraying station 102 can also be provided with a grid or guide channel, with a drain pipe connected below to collect and discharge the liquid after spraying, so as to avoid water accumulation affecting the movement or charging safety of the photovoltaic cleaning robot 300.

[0023] The temperature control component 200 includes a liquid supply structure 210 for supplying liquid and a spray structure 220 connected to the liquid supply structure. The spray structure 220 can obtain liquid from the liquid supply structure and spray the liquid onto the spray work station 102. It should be noted that the liquid can be pure water, deionized water, or coolant containing corrosion inhibitors and antifreeze to adapt to highly corrosive or extremely cold environments. In this embodiment of the invention, the liquid is preferably pure water.

[0024] Based on the structural design of this invention, after the photovoltaic cleaning robot 300 has been used for a period of time, especially during hot weather when the photovoltaic cleaning robot needs to dissipate heat quickly, the photovoltaic cleaning robot can move to the spraying work position 102. The spraying structure 220 can obtain liquid from the liquid supply structure and spray the liquid onto the spraying work position 102. After the liquid comes into contact with the photovoltaic cleaning robot 300, it can absorb heat from the photovoltaic cleaning robot 300, thereby quickly reducing the temperature of the photovoltaic cleaning robot 300 and avoiding overheating damage. This allows the photovoltaic cleaning robot 300 to not stop for a long time to dissipate heat, thus ensuring the continuity of the cleaning task and improving the utilization efficiency of the photovoltaic cleaning robot 300.

[0025] Furthermore, the spray structure 220 can remove dust and other adhering substances from the photovoltaic cleaning robot during the spraying process, preventing excessive dust accumulation that could reduce heat dissipation efficiency and ensuring the heat dissipation efficiency of the photovoltaic cleaning robot 300 during use. Moreover, the spray structure 220 has a low-speed spraying mode and a high-speed spraying mode. In the high-speed spraying mode, the amount of liquid sprayed per unit time is greater than that in the low-speed spraying mode. Thus, when only heat dissipation is needed for the photovoltaic cleaning robot 300, the low-speed spraying mode can be used to avoid liquid waste. When both heat dissipation and cleaning are required, the high-speed spraying mode can be used, utilizing the high-speed impact of the liquid to wash away dust and other adhering substances attached to the photovoltaic cleaning robot 300.

[0026] Furthermore, the integrated design of the charging chamber 100 and the temperature control component 200 allows for seamless integration of the cooling process with the charging process, reducing the space occupied by additional equipment and lowering system complexity. Additionally, the spraying station 102 is located at the inlet / outlet 101, ensuring the robot receives spraying before and after charging, effectively reducing surface and internal temperatures. This lowers the temperature before charging and also reduces the operating temperature during post-charging operations.

[0027] In another embodiment, the water distribution pipe 221 can be arranged in a ring or U shape to fully cover the top and sides of the photovoltaic cleaning robot 300. The spray nozzle angle is adjustable to achieve spraying in different directions and adapt to the shape of different robot models.

[0028] Please see Figures 1 to 4 In this embodiment of the invention, the spray structure 220 includes at least one water distribution pipe 221 and a water pump 222. Each water distribution pipe 221 is arranged above the spraying work position 102 and has at least one downward-facing spray nozzle. The water pump 222 can obtain liquid from the liquid supply structure and pump the liquid to each spray pipe. Based on this, firstly, the water distribution pipe 221 is arranged above the spraying work position 102 with the spray nozzle facing downward, forming a top-down spray coverage, ensuring that the liquid is evenly distributed on the robot surface, and gravity can also be used to enhance the spray impact force and improve the cooling effect. Secondly, the water distribution pipe 221 is located at the top, avoiding interference with the robot's movement path and reducing the risk of structural collision.

[0029] Furthermore, in other embodiments of the present invention, the connection between the water distribution pipe 221 and the water pump 222 is detachable, which facilitates the maintenance and replacement of the water distribution pipe 221 and reduces the operation and maintenance costs.

[0030] Please see Figure 4In this embodiment of the invention, the spray nozzle is detachably connected to a nozzle 223 or a plug. It should be noted that the detachable connection can employ a threaded or snap-fit ​​design, simplifying the assembly and disassembly process of the spray structure 220 and reducing manufacturing complexity.

[0031] In addition, the overheating problem of photovoltaic cleaning robots may vary depending on the season or workload. Based on the structural design, it is possible to customize the spraying strategy according to the actual situation, "for example, replacing nozzles 223 with different flow rates and spray angles, and the block can shut down redundant spray nozzles."

[0032] Please see Figures 1 to 4 In this embodiment of the invention, at least two water distribution pipes 221 are provided; Each water inlet of the branch pipe 221 is equipped with a first solenoid valve 2211.

[0033] Based on this, firstly, the addition of water distribution pipes 221 can form a more complete spray range. Secondly, the first solenoid valve 2211 independently controls the liquid flow of each water distribution pipe 221, allowing the water distribution pipes 221 to perform spraying operations independently. For example, when part of the photovoltaic cleaning robot 300 enters the spraying operation position 102, only the corresponding water distribution pipe 221 is opened to avoid liquid waste. Also, when a specific area of ​​the photovoltaic cleaning robot 300 requires a stronger spray, other water distribution pipes 221 can be closed to achieve the purpose of a stronger spray. Furthermore, if a water distribution pipe 221 fails, the other water distribution pipes 221 can still work, improving the fault tolerance rate.

[0034] Please see Figures 1 to 4 In this embodiment of the invention, the liquid supply structure 210 includes a water storage tank 211 and a heating module 212 for heating the water storage tank 211.

[0035] When the photovoltaic cleaning robot 300 operates in winter or cold regions, spraying cold water may cause components to freeze or shrink, leading to malfunctions. The heating module 212 provides warm water spray, and the liquid supply structure 210 both cools (preventing overheating) and prevents freezing. For example, in cold weather, warm water can quickly melt frost on the robot's surface. In summer, the heating module 212 can be turned off, using room temperature liquid. This design significantly improves the year-round adaptability of the temperature control device, protects the robot from extreme temperature damage, and extends its service life.

[0036] Furthermore, heating the liquid enhances cleaning effectiveness, dissolving stubborn stains on the photovoltaic cleaning robot 300 and increasing its versatility. The heating module 212 can have a built-in temperature sensor that links with the ambient temperature sensor. When the ambient temperature is lower than a set value (e.g., 5°C), heating automatically starts to maintain the liquid within a certain temperature range (e.g., 10-25°C), preventing freezing and improving cleaning performance. The heating power is adjustable to adapt to different climatic conditions.

[0037] Please see Figure 1 In this embodiment of the invention, a liquid level detection component 213 is provided inside the water storage tank 211. The liquid level detection component 213 includes a high-level liquid level sensor 2131 and a low-level liquid level sensor 2132, which are arranged vertically and located at preset positions. Photovoltaic power plants are often located in remote areas, and temperature control devices need to operate unattended. The liquid level detection component 213 ensures a continuous supply of spray liquid, preventing cooling interruptions due to water shortage and thus preventing overheating damage to the robot. For example, the low-level liquid level sensor 2132 can provide early warning of water replenishment needs and trigger the water inlet system; the high-level liquid level sensor 2131 prevents overflow and protects surrounding equipment. This improves the system's intelligence level, reduces maintenance frequency and costs, and extends the lifespan of the heating module 212 and the water tank by preventing dry burning or overfilling.

[0038] Please see Figure 4 In this embodiment of the invention, the liquid supply structure 210 further includes a water inlet pipe 214 connected to the water storage tank 211 and a second solenoid valve 215 disposed on the water inlet pipe 214. The water inlet pipe 214 is connected to an external water source (such as tap water or a recycled water system), and the supply of liquid to the water storage tank 211 can be controlled by the second solenoid valve 215.

[0039] Please see Figure 4 In this embodiment of the invention, the liquid supply structure 210 further includes a filter 216 disposed in the water inlet pipe 214; The second solenoid valve 215 is located between the filter 216 and the water storage tank 211.

[0040] Photovoltaic power station environments are often dusty, and water sources may contain sand or microorganisms. Filter 216 ensures the purity of the spray liquid, preventing nozzle blockage or pump 222 wear, thus guaranteeing continuous and stable cooling effects. For example, in arid regions where water sources contain many impurities, filter 216 can effectively purify the water and extend the lifespan of the spray structure 220. At the same time, the cleaning liquid sprayed onto the robot's surface will not leave scale, maintaining the robot's appearance and functionality.

[0041] Furthermore, the filter 216 is preferably designed to be detachable for easy replacement, and the filter 216 can be made of stainless steel filter screen, ceramic filter element or polymer filter membrane to effectively intercept particulate matter, sediment and impurities in liquid.

[0042] In this embodiment of the invention, the charging chamber 100 includes a wireless charging component for wirelessly charging the photovoltaic cleaning robot 300. Based on this, the wireless charging component and the photovoltaic cleaning robot 300 are connected for non-contact charging, reducing mechanical wear points and avoiding exposed charging interfaces, thus lowering the risk of short circuits or corrosion caused by spraying.

[0043] The photovoltaic cleaning robot 300 requires rapid charging after high-temperature operation to prepare for the next task; wireless charging eliminates the hassle of plugging and unplugging interfaces, making it especially suitable for automated scenarios. For example, during spray cooling, the robot's surface is wet, and wireless charging avoids the risk of electric shock, enhancing safety; during charging, the robot can remain stationary and receive all-around cooling.

[0044] In this embodiment of the invention, the charging chamber 100 is equipped with a cooling fan 110, which can dissipate heat from the charging chamber 100 during the charging process of the photovoltaic cleaning robot 300. The cooling fan 110 not only ventilates the charging chamber 100 during charging but also activates after spraying to accelerate the drying of the robot's surface and prevent water residue. The fan has two speed settings, high and low, which are automatically adjusted based on temperature and humidity sensors.

[0045] The present invention also proposes a cleaning robot charging station, which includes a temperature control device. The specific structure of the temperature control device is as described in the above embodiments. Since the cleaning robot charging station adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0046] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
