Description

Technical Field

[0001] This invention relates to the field of photovoltaic greenhouses, and more particularly to a photovoltaic sunshade canopy for highway service areas. Background Technology

[0002] Expressways, or highways for short, are roads specifically designed for high-speed automobile travel. Expressways are multi-lane roads with separate lanes and controlled access for automobiles. Service areas are required on expressways to provide services for passing vehicles. Currently, wind and solar power greenhouses are being installed in service areas to increase the power supply to these areas.

[0003] Existing photovoltaic sunshades used in highway service areas are simple and cannot control the movement of photovoltaic panels according to demand, ensuring that the photovoltaic panels always face upward to receive sunlight. In windy or rainy weather, they cannot be flipped over. Due to the angle of impurities in the rainwater, stains easily adhere to the protective layer on the surface of the photovoltaic panels, affecting their use. Furthermore, the surface of the photovoltaic panels cannot be thoroughly washed. Improvements are needed. Therefore, we propose a photovoltaic sunshade for highway service areas. Summary of the Invention

[0004] Purpose of the invention: The purpose of this invention is to provide a way to flip and protect photovoltaic panels; another purpose of this invention is to provide a way to wash and clean the surface of photovoltaic panels.

[0005] Technical solution: A photovoltaic sunshade canopy for highway service areas, comprising a photovoltaic mechanism, with a cleaning mechanism installed above the photovoltaic mechanism;

[0006] A support mechanism is provided below the photovoltaic mechanism;

[0007] The photovoltaic mechanism includes a mounting frame, a groove 1 is provided on the front of the upper surface of the mounting frame, a groove 2 is provided on the rear of the upper surface of the mounting frame, and multiple photovoltaic panels are provided on the inner side of the mounting frame.

[0008] A shaft is fixedly connected to the rear surface of the photovoltaic panel. The rear surface of the shaft extends into the interior of the groove and is rotatably connected to the groove via a rotating shaft. A gear is fixedly connected to the outer side wall of the shaft on the inner side of the groove. A rack is slidably connected to the outer side wall of the groove. The rack meshes with multiple gears.

[0009] A shaft column two is fixedly connected to the front surface of the photovoltaic panel located on the right side of the inner side of the mounting frame and inside the groove one. The shaft column two is rotatably connected to the groove one via a rotating shaft. A gear two is fixedly connected to the outer side wall of the shaft column two inside the groove one. An electric push rod one is fixedly connected to the inner side of the groove one. A rack two is fixedly connected to the right end of the output end of the electric push rod one. The rack two is meshed with the gear two.

[0010] The upper surface of the mounting frame is fitted with cover plates near both groove one and groove two via bolts.

[0011] Furthermore, the cleaning mechanism includes a reciprocating lead screw, a guide rod, and a transfer chamber. The right end of the transfer chamber is threadedly connected to the reciprocating lead screw, and the left end of the transfer chamber is slidably connected to the outer wall of the guide rod. Both ends of the reciprocating lead screw are rotatably connected to a first fixing plate via a rotating shaft. The bottom of the first fixing plate is fixedly connected to the upper surface of the mounting frame. The bottom of the guide rod is fixedly connected to a second fixing plate, and the bottom of the second fixing plate is fixedly connected to the upper surface of the mounting frame. Multiple nozzles are integrally formed at the bottom of the transfer chamber. A motor is fixedly connected to the front surface of the first fixing plate, which is located in front of the upper surface of the mounting frame. The rear end of the output shaft of the motor is fixedly connected to the front end of the reciprocating lead screw.

[0012] Furthermore, a take-up drum is fixedly connected to the front surface of the mounting frame, and a connecting pipe is rotatably connected to the inner rear surface of the take-up drum via a rotating shaft. The front end of the connecting pipe extends through to the front of the take-up drum and is fixedly connected to a retaining ring. The front end of the retaining ring is rotatably connected to a connecting joint via a rotating shaft. A flexible hose is wound around the outer wall of the connecting pipe and located inside the take-up drum. The end of the flexible hose away from the connecting pipe extends through to the outside of the take-up drum and communicates with the interior of the transfer cavity.

[0013] Furthermore, a torsion spring is fixedly connected to the opposite side of the retaining ring and the winding drum, and to the outside of the connecting tube.

[0014] Furthermore, the support mechanism includes a support leg, the top of which is fixedly connected to the bottom of the mounting frame.

[0015] Furthermore, a fixing strip is fixedly connected between two adjacent support legs, and a sunshade cloth is fixedly connected to the bottom of the fixing strip. Lifting sleeves are slidably connected to the outer side walls of multiple support legs below the sunshade cloth. A connecting rod is fixedly connected between two adjacent lifting sleeves, and the top of the connecting rod is fixedly connected to the bottom of the sunshade cloth.

[0016] Furthermore, a fixing sleeve is fixedly connected to the lower outer wall of the support leg located on the right side of the lower surface of the mounting frame. An electric push rod II is fixedly connected to the outer wall of the fixing sleeve. The top end of the output end of the electric push rod II is fixedly connected to the bottom of the adjacent connecting rod.

[0017] Furthermore, the outer side wall of the support leg has two limiting grooves.

[0018] Furthermore, the inner wall of the lifting sleeve is fixedly connected to a limiting block inside the limiting groove.

[0019] Beneficial effects: By controlling the retraction of the electric push rod one through the external controller, the rack two will move the gear two, causing the shaft two to rotate, which in turn causes the single photovoltaic panel fixed to the shaft two to rotate, so that multiple photovoltaic panels can rotate at the same time. This method can flip the photovoltaic panels so that the front of the photovoltaic panel can face up to receive sunlight normally, or the back can face up to protect it.

[0020] Then, the external water pumping mechanism is activated to pump water, which is sprayed out through multiple nozzles to rinse and clean the surfaces of multiple photovoltaic panels. At the same time, the motor is activated to drive the reciprocating screw between the two fixed plates to rotate, so that the transfer chamber can move back and forth under the guidance of the guide rod between the two fixed plates, increasing the rinsing range and making the rinsing more thorough.

[0021] As the transfer chamber moves backward, the hose is pulled and extends out from inside the take-up drum. At this time, the traction connecting pipe rotates, and the torsion spring is twisted and deformed. When the transfer chamber moves forward, the torsion spring returns to its original position, thereby pulling the connecting pipe to rotate, which facilitates the winding of the hose and avoids the problem of the hose being scattered after being pulled out. This allows the hose to extend or retract according to the movement of the transfer chamber.

[0022] By controlling the extension or retraction of the electric push rod, and with the connection of multiple connecting rods and multiple lifting sleeves, multiple lifting sleeves can be controlled to rise or fall along the outer side wall of multiple support legs as a whole. This allows the sunshade cloth to be pulled down to unfold or raised to store, making it easy to adjust the sunshade according to needs. The limiting groove and limiting block restrict the up and down movement of the lifting sleeves, playing a guiding and limiting role. Attached Figure Description

Detailed Implementation

[0033] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Example

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a photovoltaic sunshade canopy for a highway service area is provided, including a photovoltaic mechanism 1;

[0036] The photovoltaic mechanism 1 includes a mounting frame 101. A groove 102 is formed at the front of the upper surface of the mounting frame 101, and a groove 103 is formed at the rear of the upper surface of the mounting frame 101. Multiple photovoltaic panels 104 are arranged inside the mounting frame 101. A shaft 105 is fixedly connected to the rear surface of each photovoltaic panel 104. The rear surface of the shaft 105 extends into the interior of the groove 103 and is rotatably connected to the groove 103 via a rotating shaft. A gear 106 is fixedly connected to the outer wall of the shaft 105 inside the groove 103. A rack 107 is slidably connected to the outer wall of the groove 103, and the rack 107 meshes with the multiple gears 106. The photovoltaic panel 104, located on the right side inside the mounting frame 101, has a shaft 108 fixedly connected to its front surface inside the first groove 102. The shaft 108 is rotatably connected to the first groove 102 via a rotating shaft. A gear 109 is fixedly connected to the outer wall of the shaft 108 inside the first groove 102. An electric push rod 110 is fixedly connected to the inner side of the first groove 102. A rack 111 is fixedly connected to the right end of the output end of the electric push rod 110. The rack 111 meshes with the gear 109. A cover plate 112 is installed on the upper surface of the mounting frame 101 near the first groove 102 and the second groove 103 by bolts.

[0037] Under normal conditions, the electric push rod 110 is in the extended state, and multiple photovoltaic panels 104 are laid flat inside the mounting frame 101. At this time, the mounting frame 101 tilts itself to receive sufficient sunlight, and the multiple photovoltaic panels 104 and the mounting frame 101 form a canopy that can provide shade to the area below.

[0038] When strong winds or rain occur, the electric push rod 110 can be retracted by an external controller. At this time, rack 111 will move gear 109, causing shaft 108 to rotate. This, in turn, causes the individual photovoltaic panel 104 fixed to shaft 108 to rotate. Since multiple photovoltaic panels 104 are rotatably connected to groove 103 via shaft 105, and multiple gears 106 fixed to the outer walls of shaft 105 mesh with rack 107, when one photovoltaic panel 104 is rotated, the corresponding shaft 105 will rotate together. This causes rack 107 to slide, causing the remaining gears 106 to be moved together. This, in turn, drives the corresponding shafts 105 to rotate, allowing multiple photovoltaic panels 104 to rotate simultaneously. This method can flip the photovoltaic panels 104 so that they can face upwards to receive sunlight normally, or face downwards for protection.

[0039] like Figure 5 and Figure 6 As shown, a cleaning mechanism 2 is installed above the photovoltaic mechanism 1;

[0040] The cleaning mechanism 2 includes a reciprocating screw 201, a guide rod 202, and a transfer cavity 203. The right end of the transfer cavity 203 is threadedly connected to the reciprocating screw 201, and the left end of the transfer cavity 203 is slidably connected to the outer wall of the guide rod 202. The two ends of the reciprocating screw 201 are rotatably connected to a fixing plate 204 via a rotating shaft. The bottom of the fixing plate 204 is fixedly connected to the upper surface of the mounting frame 101. The bottom of the guide rod 202 is fixedly connected to a fixing plate 205. The bottom of the fixing plate 205 is fixedly connected to the upper surface of the mounting frame 101. The bottom of the transfer cavity 203 is integrally formed with multiple nozzles 206. A motor 213 is fixedly connected to the front surface of the fixing plate 204 located in front of the upper surface of the mounting frame 101. The rear end of the output shaft of the motor 213 is fixedly connected to the front end of the reciprocating screw 201.

[0041] A take-up drum 207 is fixedly connected to the front surface of the mounting frame 101. A connecting pipe 208 is rotatably connected to the inner rear surface of the take-up drum 207 via a rotating shaft. The front end of the connecting pipe 208 extends to the front of the take-up drum 207 and is fixedly connected to a retaining ring 209. The front end of the retaining ring 209 is rotatably connected to a connecting head 210 via a rotating shaft. A flexible hose 211 is wound around the outer wall of the connecting pipe 208 and located inside the take-up drum 207. The end of the flexible hose 211 away from the connecting pipe 208 extends to the outside of the take-up drum 207 and communicates with the interior of the transfer cavity 203.

[0042] A torsion spring 212 is fixedly connected to the opposite side of the retaining ring 209 and the winding drum 207, and to the outside of the connecting pipe 208.

[0043] When it is necessary to clean the surface of the photovoltaic panel 104, the connector 210 is connected to an external water source;

[0044] Then, the external pumping mechanism is activated to pump water, so that the water passes through the connector 210, connector 208, hose 211, and transfer chamber 203, and is then sprayed out through multiple nozzles 206 to rinse and clean the surfaces of multiple photovoltaic panels 104.

[0045] At the same time, the motor 213 is started, which drives the reciprocating screw 201 between the two fixed plates 204 to rotate, so that the transfer chamber 203 can move back and forth under the guidance of the guide rod 202 between the two fixed plates 205, which increases the rinsing range and makes the rinsing more thorough.

[0046] As the transfer chamber 203 moves backward, the hose 211 is pulled and extends out from inside the take-up drum 207. At this time, the traction-driven connecting pipe 208 will rotate, and the torsion spring 212 will be torsionally deformed. When the transfer chamber 203 moves forward, the torsion spring 212 returns to its original position, thereby pulling the connecting pipe 208 to rotate, which facilitates the winding of the hose 211 and avoids the problem of the hose 211 being scattered after being pulled out. This allows the hose 211 to extend or rewind according to the movement of the transfer chamber 203.

[0047] like Figure 7 , Figure 8 and Figure 9 As shown, a support mechanism 3 is provided below the photovoltaic mechanism 1;

[0048] The support mechanism 3 includes a support leg 301, the top of which is fixedly connected to the bottom of the mounting frame 101;

[0049] A fixing strip 302 is fixedly connected between two adjacent support legs 301. A sunshade cloth 303 is fixedly connected to the bottom of the fixing strip 302. A lifting sleeve 304 is slidably connected to the outer side wall of multiple support legs 301 below the sunshade cloth 303. A connecting rod 305 is fixedly connected between two adjacent lifting sleeves 304. The top of the connecting rod 305 is fixedly connected to the bottom of the sunshade cloth 303.

[0050] A fixing sleeve 306 is fixedly connected to the lower outer wall of the support leg 301 located on the right side of the lower surface of the mounting frame 101. An electric push rod 307 is fixedly connected to the outer wall of the fixing sleeve 306. The top end of the output end of the electric push rod 307 is fixedly connected to the bottom of the adjacent connecting rod 305.

[0051] The outer side wall of the support leg 301 has two limiting grooves 308;

[0052] The inner wall of the lifting sleeve 304 is fixedly connected to the limiting block 309 inside the limiting groove 308;

[0053] The device is supported by multiple support legs 301 and can block the sun from all sides with multiple sunshade cloths 303 to enhance the sunshade effect. By controlling the extension or retraction of the electric push rod 307, and with the connection of multiple connecting rods 305 and multiple lifting sleeves 304, the multiple lifting sleeves 304 can be controlled to rise or fall along the outer wall of the multiple support legs 301 as a whole. This can pull the sunshade cloths 303 to fall and unfold, or rise and retract, so as to adjust the sunshade as needed. The limiting groove 308 and the limiting block 309 restrict the up and down movement of the lifting sleeves 304, which serves as a guiding and limiting effect.

[0054] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
