Description

Technical Field

[0001] This invention relates to the field of clean energy combined with diesel engine energy storage technology, and in particular to a clean power generation device combining photovoltaic and diesel engines. Background Technology

[0002] A combined photovoltaic and diesel engine clean power generation device is an energy solution that balances stability and environmental friendliness.

[0003] In backup power systems for remote areas, islands, and critical facilities, a hybrid power supply model combining diesel generators, photovoltaics, and energy storage batteries has become the mainstream solution for improving reliability and reducing fuel consumption and carbon emissions. However, this solution suffers from a long-neglected but significant technical problem: the exhaust gases from diesel engines contain a large amount of sticky particulate matter. These particles are dispersed by the wind and easily adhere to the surface of nearby photovoltaic panels, forming a layer of dirt that significantly blocks sunlight and reduces power generation efficiency. Current technologies typically only redirect the diesel engine exhaust pipe away from the photovoltaic array, but this cannot completely eliminate these unorganized, dispersed sticky particles. Once these particles settle on the solar photovoltaic panels, they are difficult to remove naturally by rainwater, requiring frequent manual cleaning. This is particularly problematic in remote, water-scarce, or high-altitude environments, resulting in high maintenance costs and risks. Therefore, ensuring the cleanliness of the photovoltaic panel surface when combining photovoltaic and diesel power generation is a problem that needs to be solved. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a combined photovoltaic and diesel engine clean power generation device, which solves the problem of ensuring the cleanliness of the photovoltaic panel surface when photovoltaic power generation and diesel power generation are used in combination.

[0005] To achieve the above objectives, the present invention provides a combined clean power generation device of photovoltaic and diesel engine, comprising a base, a mounting frame fixedly connected to the upper surface of the base, a diesel engine fixedly connected to the mounting frame, a generator fixedly connected to the diesel engine, an energy storage power supply fixedly connected to the upper surface of the base, the generator and the energy storage power supply connected by wires, a cyclone separator connected to the exhaust port of the diesel engine, a support column fixedly installed on the upper surface of the base and on the side of the mounting frame away from the cyclone separator, a solar photovoltaic panel fixedly connected to the upper end of the support column, the solar photovoltaic panel connected by wires to the energy storage power supply, and a fixing frame fixedly connected to the upper surface of the base and on one side of the solar photovoltaic panel.

The water pump is connected to the water storage tank through a connecting water pipe. An environmental monitor is installed on the upper side of the solar photovoltaic panel. The environmental monitor is communicatively connected to the water pump and the multi-stage electric actuator.

[0006] Optionally, the diesel engine's outlet is equipped with an intake pipe, which enters the cyclone separator tangentially. A dust collection bin is fixedly connected to the lower end of the cyclone separator, and an outlet pipe is fixedly connected to the upper end of the cyclone separator.

[0013] Optionally, when the environmental monitor detects rain, it sends a signal to control the multi-stage electric push rod to extend and retract multiple times. When the environmental monitor detects that the time without rain has reached a preset time, it sends a signal to control the multi-stage electric push rod to extend and retract multiple times, and at the same time starts the water pump to pump water and spray.

[0014] Preferably, the frequency at which the environmental monitor sends signals to the multi-stage electric actuator is set at intervals as needed.

[0015] The photovoltaic and diesel engine combined clean power generation device of the present invention can not only treat the exhaust gas from the tail end of the diesel engine and collect large particulate matter in the exhaust gas, but also clean the surface of the photovoltaic panel with rainwater directly using the cleaning brush when it rains. If it does not rain for a long time, the water pump draws water from the storage tank and sprays it out through the spray pipe before cleaning it with the cleaning brush, keeping the surface of the photovoltaic panel clean and thus ensuring power generation efficiency.

A multi-stage electric push rod 4 is fixedly connected to the fixed frame 3. A connecting frame is fixedly connected to the end of the multi-stage electric push rod 4.

A water pump is fixedly installed on the upper surface of the base 1 and below the solar photovoltaic panel 2. A water inlet pipe 11 is fixedly connected to the upper end of the water pump 12. A spray pipe 6 is fixedly connected to the upper end of the water inlet pipe 11. A water storage tank 7 is fixedly connected to the upper surface of the base 1 and on the other side of the solar photovoltaic panel 2. The water pump 12 is connected to the water storage tank 7 through a connecting water pipe. An environmental monitor 10 is installed on the upper side of the solar photovoltaic panel 2. The environmental monitor 10 is communicatively connected to the water pump 12 and the multi-stage electric push rod 4. Specifically, when the environmental monitor 10 detects rain, it sends a signal to control the multi-stage electric push rod 4 to extend and retract multiple times. When the environmental monitor 10 detects that the time without rain has reached a preset time, it sends a signal to control the multi-stage electric push rod 4 to extend and retract multiple times, and simultaneously starts the water pump 12 to pump water for spraying. That is, during normal rain, natural rainwater is used in conjunction with the cleaning brush for scrubbing, and rainwater is collected. When there is no rain for a long period and the set time has passed, the rainwater collected in the storage tank is used for spraying and cleaning. The water pump is provided to facilitate the delivery of water from the storage tank to the spray pipe, the multi-stage electric push rod is provided to facilitate the reciprocating motion of the cleaning brush for cleaning, and the spray pipe is provided to facilitate the spraying of water.

[0025] Optionally, the diesel engine 20 has an intake pipe 14 at its outlet. The intake pipe 14 enters the cyclone separator 17 tangentially. A dust collection bin 15 is fixedly connected to the lower end of the cyclone separator 17, and an outlet pipe 18 is fixedly connected to the upper end of the cyclone separator 17. The intake pipe 14 enters the cyclone separator 17 tangentially to achieve the purpose of rotational centrifugation followed by sedimentation, which facilitates better collection of emissions.

[0026] Preferably, a fan 19 is fixedly installed on the upper surface of the base 1 and on the side of the cyclone separator 17, the air outlet pipe 18 is fixedly connected to the air inlet of the fan 19, and the exhaust port 22 of the fan 19 faces away from the solar photovoltaic panel 2.

[0027] Optionally, a water receiving hopper 8 is provided at the top of the water storage tank 7. This facilitates better collection of rainwater.

[0028] Preferably, a filter screen 9 is provided at the contact point between the water receiving hopper 8 and the water storage tank 7. This facilitates the filtration of impurities in the rainwater.

[0029] Optionally, multiple nozzles are evenly fixedly connected to the lower surface of the spray pipe 6. This facilitates even spraying.

[0030] Optionally, the environmental monitor 10 is fixed to the upper surface of the base 1 by a mounting rod. This facilitates the fixed installation of the environmental monitor.

[0031] Optionally, a cleaning brush 5 can be detachably and fixedly connected to the connecting end of the connector. This facilitates brush replacement and maintenance, and the soft brush will not damage the surface of the photovoltaic panel while achieving a good cleaning effect.

[0032] The working principle of the combined photovoltaic and diesel engine clean power generation device of the present invention is as follows: When in use, the electricity generated by the solar photovoltaic panel 1 is stored in the energy storage power supply 16. When the solar photovoltaic panel 2 stops generating electricity or the power generation is unstable, the diesel engine 20 starts the generator 21 to generate electricity and store it in the energy storage power supply 16. At this time, the exhaust gas generated by the diesel engine is sucked into the cyclone separator 17 by the action of the fan 19. With the centrifugal action, large oily dust particles in the exhaust gas fall into the dust collection bin 15 at the bottom. The separated gas is discharged through the exhaust port 22. If a small amount of oily particles remain in the discharged gas, they will fall onto the solar photovoltaic panel 2, thus affecting the power generation efficiency. When the environmental monitor 10 detects rain, it sends a signal to control the multi-stage electric push rod 4 to extend and retract multiple times, and the cleaning brush 5 cleans the solar photovoltaic panel 2. When the environmental monitor 10 detects that the time without rain has reached the preset time, it sends a signal to control the multi-stage electric push rod 4 to extend and retract multiple times. At the same time, the water pump 12 is started to draw water from the water storage tank 7 and spray water mist through the nozzle below the water spray pipe 6. Together with the cleaning brush 5, the solar photovoltaic panel 2 is cleaned and the panel surface is kept clean.

[0033] The photovoltaic and diesel engine combined clean power generation device of the present invention can not only treat the exhaust gas from the tail end of the diesel engine and collect large particulate matter in the exhaust gas, but also clean the surface of the photovoltaic panel with rainwater directly using the cleaning brush when it rains. If it does not rain for a long time, the water pump draws water from the storage tank and sprays it out through the spray pipe before cleaning it with the cleaning brush, keeping the surface of the photovoltaic panel clean and thus ensuring power generation efficiency.

[0034] The present invention has been described in the above-described embodiments; however, these embodiments are merely examples for implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the present invention. Conversely, any modifications and refinements made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
