Description

Technical Field

[0001] The invention relates to a photovoltaic power generation device, in particular to a household photovoltaic panel based on intelligent electrical equipment. Background Art

[0002] Household solar panels are the core part of the solar power generation system. The function of solar panels is to convert the sun's light energy into electrical energy, and then output direct current to store in the battery. Solar panels are one of the most important components in household solar power generation. Their conversion rate and service life are important factors that determine whether solar cells are valuable. However, existing household photovoltaic panels still have some shortcomings in actual use. For example, most existing household photovoltaic panels are set on the top of the house or in some high places that are not easily accessible, so that they can receive light. However, after working for a long time, dust will accumulate on the surface of the photovoltaic panels at a high place. When encountering slow-flowing rainwater, mud will form. After drying, it will adhere to the surface of the photovoltaic panels, which will hinder the photovoltaic panels from absorbing light energy. Photovoltaic panels at a high place are not convenient to clean stains, which reduces the practicality of the device. Summary of the invention

[0003] The purpose of the present invention is to provide a household photovoltaic panel based on intelligent electrical equipment to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, a household photovoltaic panel based on intelligent electrical equipment is provided, including a bracket device, two shielding devices are arranged above the bracket device, and a diversion device is arranged below the shielding device. When it rains, rainwater gathers from the bracket device and hits the diversion device downward, and the diversion device slides downward to drive the two shielding devices to approach each other, and the bracket device is shielded by the shielding device. When the two shielding devices cover the bracket device, the shielding device blocks the rainwater from continuing to hit the diversion device downward, and guides the rainwater to gather in the diversion device, so that the diversion device continues to slide downward, and the diversion device sprays the collected rainwater onto the bracket device. When the rainwater in the diversion device is reduced, the diversion device slides upward, driving the two shielding devices away from each other.

[0005] As a further improvement of the present technical solution, the bracket device includes a plate body, baffles are fixedly installed on both sides of the plate body, and a water diversion plate is slidably installed between the plate body and the baffle. On sunny days, the two water diversion plates move away from each other and shrink under the baffle. When it rains, the two water diversion plates approach each other and shield the bracket device. Scraping strips are installed on the side where the two water diversion plates are close to each other, and when the water diversion plates slide, they drive the scraping strips to scratch the plate body.

[0006] As a further improvement of the present technical solution, a mounting frame is installed on the side of the plate body close to the shielding device in the vertical direction, and the mounting frame consists of two smooth columns and a crossbeam. Single pulleys are fixedly installed under both ends of the crossbeam, and double pulleys are provided on both sides of the single pulley away from each other. The double pulleys are fixedly connected to the bottom end of the baffle, and a counterweight block is provided below the double pulley.

[0007] As a further improvement of the technical solution, a traction block is fixedly installed on the side close to the lower ends of the two water guide plates, and a second traction rope is fixedly connected to the side of the traction block close to the baffle. The second traction rope passes through the double pulley and is connected to the counterweight block. The two traction blocks are fixedly connected to the sides away from each other with the first traction rope. The first traction rope connected to each traction block passes through each other and passes through the double pulley and the single pulley away from itself in turn.

[0008] As a further improvement of the present technical solution, the other end of the first traction rope is fixedly connected to a water tank, and rings are symmetrically installed on the side walls of the water tank. The rings are sleeved on the sliding column and slide. The counterweight block pulls the two traction blocks away from each other through the second traction rope. When the two traction blocks move away from each other, the water tank is pulled up through the first traction rope. When the water tank slides down, the two traction blocks are pulled closer to each other through the first traction rope. When the two traction blocks are close to each other, the counterweight block is pulled up through the second traction rope.

[0009] As a further improvement of the present technical solution, a water pump and a float liquid level switch are installed inside the water tank. The on and off of the switch is controlled by the up and down movement of the float in the float liquid level switch. When the liquid level inside the water tank is higher than the set liquid level, the float rises to connect the switch and start the water pump.

[0010] As a further improvement of the present technical solution, the water outlet of the water pump is connected to an outlet pipe, the other end of the outlet pipe is connected to a hollow slide pipe, the hollow slide pipe is arranged above the plate body, and a plurality of nozzles are installed on the side wall of the water tank close to the plate body. The fan blades of the water pump rotate to transport the rainwater inside the water tank through the outlet pipe to the hollow slide pipe, and spray it onto the surface of the plate body through the nozzle.

[0011] As a further improvement of the present technical solution, a water trough is fixedly installed on one side of the bottom of the plate body close to the traction block, and rainwater flows into the water trough through the surface of the plate body. A tee is connected below the water trough, and the bottom of the tee is set to be an opening. Rainwater on the surface of the plate body hits the water tank below the tee through the opening, causing the water tank to slide downward, and then the two water diversion plates are pulled out from under the baffle. A guide groove that is wide at the top and narrow at the bottom is provided on the upper side of the water diversion plate, and a drainage hole that penetrates the water diversion plate is provided at the bottom of the guide groove. Rainwater on the water diversion plate is collected into the water trough through the drainage hole.

[0012] As a further improvement of the present technical solution, a flap is rotatably installed on the side wall of the middle section of the tee head. The flap flips in the middle section of the tee head. Rainwater impacts the flap to cause the flap to flip downward. An L-shaped baffle is fixedly installed on the bottom of a traction block. A connecting plate is fixedly connected to one side of the flap outside the tee head. The baffle prevents the connecting plate from flipping upward.

[0013] As a further improvement of the present technical solution, a water inlet pipe is connected above the opening of the tee, and the other end of the water inlet pipe is connected to the interior of the water tank. When the interior of the water tank is closed, rainwater overflows into the water inlet pipe and is collected into the water tank through the water inlet pipe.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the household photovoltaic panel based on intelligent electrical equipment, the first traction rope connected to the water tank that slides downward pulls the two traction blocks closer to each other, thereby driving the two water guide plates connected to the two traction blocks closer to each other, and the surface of the board body is covered by the water guide plates to prevent rainwater from directly dripping on the surface of the board body and combining with dust to form mud when it rains, thereby avoiding the mud from blocking the board body from absorbing light energy. When the weight of the water tank decreases, the counterweight block connected by the second traction rope pulls the two traction blocks away from each other, exposing the board body to the sun, thereby ensuring the contact area between the board body and the sun, so that the board body can effectively absorb light energy.

[0016] 2. In the household photovoltaic panel based on intelligent electrical appliances, the collected rainwater is utilized by a water pump installed inside the water tank. When the liquid level is higher than the water pump start position, the water pump is started by the float liquid level switch, and the rainwater is sprayed out from the nozzle on the hollow slide pipe along the outlet pipe, thereby flushing the surface of the panel, reducing the dust covering the surface of the panel, and ensuring the efficiency of the panel in absorbing light energy.

[0017] 3. In the household photovoltaic panel based on intelligent electrical appliances, the liquid in the three-way head is diverted by a flap. When rainwater flows into the three-way head from the surface of the board body, the flap flips downward, causing the rainwater to flow out from the opening and impact the water tank in the hole, causing the water tank to slide downward, thereby pulling the two traction blocks closer together; when the two traction blocks contact each other, a baffle installed under one traction block prevents the connecting plate from flipping upward, thereby preventing the flap from flipping downward, causing the flap to block the rainwater in the three-way head, and the accumulated rainwater overflows into the water inlet pipe and flows into the water tank through the water inlet pipe, causing the water tank to continue to slide downward while the liquid level in the water tank rises. When the liquid level is higher than the water pump start position, the water pump is started through the float liquid level switch, thereby flushing the dust on the surface of the board body, so that the board body can effectively absorb light energy.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1

[0035] See also Figure 1-Figure 10 As shown, the purpose of this embodiment is to provide a household photovoltaic panel based on intelligent electrical equipment, including a bracket device 1, the bracket device 1 includes a plate body 11, and two shielding devices 2 are arranged above the plate body 11. The shielding device 2 is used to shield the plate body 11 to prevent rainwater from encountering dust on the plate body 11 to form mud. The mud forms stains after drying and adheres to the surface of the plate body 11. The stains containing dust will hinder the photovoltaic panel from absorbing light energy. A guide device 3 is arranged below the shielding device 2. When it rains, rainwater gathers from the bracket device 1 and impacts the guide device 3 downward, providing the guide device 3 with an initial downward kinetic energy. When the guide device 3 slides downward, it drives the two shielding devices 2 to approach each other and shield the plate body 11 through the shielding device 2, thereby preventing rain. Water falls on the plate body 11. When the two shielding devices 2 cover the bracket device 1, the shielding device 2 blocks the rain from continuing to impact the diversion device 3 downward, and guides the rain to gather in the diversion device 3. The diversion device 3 slides downward under the action of the gravity of the rain, and the collected rainwater is sprayed onto the plate body 11 through the diversion device 3, thereby washing away the dust on the plate body 11, thereby reducing the dust accumulated on the plate body 11, so that the household photovoltaic panel based on smart electrical appliances can effectively absorb light energy. When the rainwater in the diversion device 3 is reduced, due to the reduction of gravity, the diversion device 3 slides up, driving the two shielding devices 2 away from each other, so that the plate body 11 can directly contact the sunlight when the weather is clear, thereby ensuring the light energy absorption efficiency of the household photovoltaic panel based on smart electrical appliances.

[0036] Baffles 14 are fixedly installed on both sides of the plate body 11, and a water diversion plate 21 is slidably installed between the plate body 11 and the baffle 14. The plate body 11 is shielded by the water diversion plate 21 to prevent rainwater from directly contacting the plate body 11. On sunny days, the two water diversion plates 21 are away from each other and retracted under the baffle 14. The baffle 14 is covered by the water diversion plate 21 to prevent dust from falling on the surface of the baffle 14 and polluting the rainwater on the surface of the baffle 14 on rainy days. When it rains, the two water diversion plates 21 are close to each other and shield the plate body 11. A scraper strip 22 is installed on the side where the two water diversion plates 21 are close to each other. When the water diversion plate 21 slides, it drives the scraper strip 22 to scratch the plate body 11, thereby scraping off dust or stains on the surface of the plate body 11, further ensuring the cleanliness of the surface of the plate body 11, so that the household photovoltaic panel based on smart electrical appliances can absorb light energy more effectively.

[0037] A mounting frame 12 is installed on one side of the plate body 11 close to the shielding device 2 in the vertical direction. The mounting frame 12 is composed of two smooth columns and a crossbeam. Single pulleys 24 are fixedly installed below both ends of the crossbeam. Double pulleys 25 are arranged on both sides of the single pulley 24 away from each other. The double pulley 25 is fixedly connected to the bottom end of the baffle 14. A counterweight 26 is arranged below the double pulley 25. A second traction rope 251 is fixedly connected to one side of the traction block 23 close to the baffle 14. The second traction rope 251 passes through the double pulley 25 and is connected to the counterweight 26, so that the counterweight 26 pulls the traction block 23 when it falls. The two traction blocks 23 slide toward the side close to the baffle 14, so that the two water guide plates 21 move away from each other. The sides of the two traction blocks 23 that move away from each other are fixedly connected with the first traction rope 241. The first traction rope 241 connected to each traction block 23 passes through each other and passes through the double pulley 25 and the single pulley 24 that are away from themselves in turn. When the two traction blocks 23 move away from each other, the other end of the first traction rope 241 slides downward through the double pulley 25 and the single pulley 24. When the two traction blocks 23 move toward each other, the other end of the first traction rope 241 slides upward through the double pulley 25 and the single pulley 24.

[0038] The other end of the first traction rope 241 is fixedly connected to the water tank 31, and the side walls of the water tank 31 are symmetrically installed with rings, which are sleeved on the sliding column and slide, and the moving range of the equipment or device is limited by limiting the position, thereby preventing equipment damage and ensuring that the equipment works in the correct position. The counterweight block 26 pulls the two traction blocks 23 away from each other through the second traction rope 251, thereby driving the two water diversion plates 21 to extend from under the baffle 14 and cover the plate body 11. When the two traction blocks 23 move away from each other, the water tank 31 is pulled up and suspended in the air by the first traction rope 241, and the lifting and lowering of the water tank 31 is controlled by the volume of rainwater inside the water tank 31. When the water tank 31 slides down, the two traction blocks 23 are pulled close to each other by the first traction rope 241. When the two traction blocks 23 are close to each other, the counterweight block 26 is pulled up by the second traction rope 251.

[0039] A water pump and a float level switch are installed inside the water tank 31. The float level switch is mainly composed of a float, a magnet, a reed switch or a magnetic reed switch, a shell and other parts. A ring magnet is usually installed inside the float, and the reed switch is installed in a closed non-magnetic tube. This tube passes through the float. When the liquid level in the water tank 31 rises, the float rises accordingly, driving the magnet in the float close to the reed switch. When the magnetic force of the magnet is strong enough, the contacts of the reed switch will close, and a switch signal is usually output from normally open to closed; when the liquid level drops, the float drops accordingly, and the magnet in the float moves away from the reed switch. When the magnetic force is not enough to keep the contacts of the reed switch closed, the contacts will be disconnected, and another switch signal is usually output from closed to normally open. The on and off of the switch is controlled by the up and down movement of the float, and then the start and stop of the water pump are controlled. When the liquid level in the water tank 31 is higher than the set liquid level, the switch is connected to start the water pump. When the liquid level in the water tank 31 is lower than the set liquid level, the switch is disconnected and the water pump is turned off.

[0040] The water outlet of the water pump is connected to an outlet pipe 32, and the other end of the outlet pipe 32 is connected to a hollow slide pipe 33. The hollow slide pipe 33 is arranged above the plate body 11. A plurality of nozzles are installed on the side wall of the water tank 31 close to the plate body 11. When the liquid level inside the water tank 31 is higher than the set liquid level, the water pump is started by the float liquid level switch, and the fan blades of the water pump rotate to transport the rainwater inside the water tank 31 through the outlet pipe 32 to the hollow slide pipe 33, and spray it onto the surface of the plate body 11 through the nozzle, thereby flushing the dust on the surface of the plate body 11, so that the surface of the plate body 11 is cleaner, which is beneficial to improving the absorption of light energy by the plate body 11.

[0041] A water trough 13 is fixedly installed on one side of the bottom of the plate body 11 near the traction block 23. Rainwater flows into the water trough 13 through the surface of the plate body 11. A tee 35 is connected to the bottom of the water trough 13. The bottom of the tee 35 is set as an opening. Rainwater on the surface of the plate body 11 hits the water tank 31 below the tee 35 through the opening, causing the water tank 31 to slide downward, thereby pulling the two water guide plates 21 out from under the baffle 14, and at the same time lifting the counterweights 26 on both sides and suspending them in the air. A guide groove that is wide at the top and narrow at the bottom is opened on the upper side of the water guide plate 21, and a drainage hole that penetrates the water guide plate 21 is opened at the bottom of the guide groove. Rainwater on the water guide plate 21 is collected into the water trough 13 through the drainage hole and flows into the tee 35.

[0042] A flap 351 is rotatably mounted on the side wall of the middle section of the tee head 35. The flap 351 flips over in the middle section of the tee head 35. Rainwater impacts the flap 351 to flip it downward, so that a gap is formed between the flap 351 and the side wall of the tee head 35. The rainwater continues to flow downward from the gap and impacts the water tank 31. An L-shaped baffle 231 is fixedly mounted on the bottom of a traction block 23. A connecting plate 352 is fixedly connected to one side of the flap 351 outside the tee head 35. The baffle 231 prevents the connecting plate 352 from flipping upward, so that the flap 351 separates the tee head 35 into an upper and lower section. Rainwater has no way to flow into the upper section when flowing into the upper section. The rainwater flows downward through the flap 351, and then continues to accumulate and overflows upward. An inlet pipe 34 is connected above the opening of the tee head 35, and the other end of the inlet pipe 34 is connected to the interior of the water tank 31. When the interior of the water tank 31 is closed, rainwater overflows into the inlet pipe 34, and is collected into the water tank 31 through the inlet pipe 34, so that the liquid level in the water tank 31 continues to rise, and the rainwater is pumped by the water pump to flush the surface of the plate body 11. When the liquid level drops below the closed position of the float liquid level switch, under the pull of the counterweight block 26, the two water diversion plates 21 move away from each other and shrink under the baffle 14, and the water tank 31 is lifted at the same time.

[0043] The present invention pulls the two traction blocks 23 closer to each other through the first traction rope 241 connected to the water tank 31 that slides downward, thereby driving the two water guide plates 21 connected to the two traction blocks 23 closer to each other, and the surface of the board body 11 is covered by the water guide plates 21 to prevent rainwater from directly dripping on the surface of the board body 11 and combining with dust to form mud when it rains, thereby preventing the mud from blocking the board body 11 from absorbing light energy. When the weight of the water tank 31 decreases, the counterweight block 26 connected by the second traction rope 251 pulls the two traction blocks 23 in a direction away from each other, so that the board body 11 is exposed to the sun, thereby ensuring the contact area between the board body 11 and the sun, so that the board body 11 can effectively absorb light energy; the collected rainwater is utilized by the water pump installed inside the water tank 31. When the liquid level is higher than the water pump start position, the water pump is started by the float liquid level switch, and the rainwater is sprayed out from the nozzle on the hollow slide pipe 33 along the outlet pipe 32, thereby flushing the surface of the board body 11. , reducing the dust covering the surface of the plate body 11, ensuring the absorption efficiency of the plate body 11 to light energy; the liquid in the three-way head 35 is diverted by the flap 351, and when rainwater flows into the three-way head 35 from the surface of the plate body 11, the flap 351 flips downward, causing the rainwater to flow out from the opening and impact the water tank 31 of the hole, causing the water tank 31 to slide downward, thereby pulling the two traction blocks 23 closer together; when the two traction blocks 23 contact each other, the baffle 231 installed under one traction block 23 blocks the connection The connecting plate 352 flips upward, thereby blocking the flap 351 from flipping downward, so that the flap 351 blocks the rainwater in the three-way head 35, and the accumulated rainwater overflows into the water inlet pipe 34 and flows into the water tank 31 through the water inlet pipe 34, so that the water tank 31 continues to slide downward and the liquid level in the water tank 31 rises. When the liquid level is higher than the water pump starting position, the water pump is started through the float liquid level switch, and then the dust on the surface of the plate body 11 is washed away, so that the plate body 11 can effectively absorb light energy.

[0044] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
