Description

Technical Field

[0001] The invention relates to a photovoltaic device with a closing protection function, belonging to the technical field of photovoltaic devices. Background Art

[0002] Coastal photovoltaic devices usually refer to solar power generation facilities built in coastal areas, especially on coastal beaches or nearby waters. This type of device takes advantage of the vast area, abundant sunshine resources and specific environmental conditions of coastal areas to achieve efficient use of clean energy. It has the advantages of abundant sunshine resources, environmental friendliness and high economic benefits. However, coastal areas are often attacked by heavy rains. Existing photovoltaic devices are relatively simple. Rainwater in heavy rains carries a lot of energy when it falls from the sky, which can easily damage the surface of photovoltaic panels. Therefore, it is necessary to design a photovoltaic device that can protect photovoltaic panels during heavy rains.

[0003] The Chinese utility model patent with the patent announcement number CN220383005U discloses a photovoltaic panel with a waterproof structure. It includes a support base and a photovoltaic panel body. The top of the support base is provided with a bottom plate. The photovoltaic panel body is fixedly connected to the top of the bottom plate. Both sides of the top of the bottom plate are fixedly connected with a starting component, and a shielding component is connected between the two starting components. It uses a shielding component connected to the surface below the bottom plate, and the other end of the shielding component is connected to two starting components. In rainy and snowy weather, the starting component can be started, so that the starting component drives the shielding component to slide on the surface of the photovoltaic panel body, thereby facilitating the protection of the surface of the photovoltaic panel body, and effectively reducing the situation where the photovoltaic panel body is eroded by rain and snow, causing damage to its internal electronic components.

[0004] However, the above-mentioned patent only provides a shielding component above the photovoltaic panel body to protect the photovoltaic panel body inside, and the inclined photovoltaic panel makes the shielding component hit over a larger area when hit by heavy rain, which can easily cause damage to the shielding component, thereby making the photovoltaic panel unable to be effectively protected.

[0035] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Among them, for the convenience of explanation, the two ends in the embodiment refer to the front and rear directions, and the two sides refer to the left and right directions; unless otherwise specified, the front and rear, left and right in the embodiment are all based on the front and rear, left and right directions when the installation frame 23 is in the open state.

[0037] See also Figure 1-Figure 13A photovoltaic device with a closing protection function comprises a base plate 1, a mounting plate 2, a mounting frame 23 and a photovoltaic panel 24, wherein the photovoltaic panel 24 is fixed in the mounting frame 23, and the two mounting plates 2 are vertically fixed to the upper ends of the left and right sides of the horizontal base plate 1; the bottom of the mounting frame 23 is covered and fixed with a protective shell 25; the front and rear ends of the upper part of the mounting plate 2 are respectively provided with two obtuse-angle sliding grooves 21 that penetrate horizontally and are mirror-symmetrical; a slider 22 is respectively fixed to the bottom of the two outer sides of the mounting frame 23, and the two sliders 22 of the same mounting frame 23 are respectively slidably arranged in the obtuse-angle sliding groove 21 located at the same end of the two mounting plates 2; a folding component 3 is fixed to the inner side of the mounting plate 2; the upper part of the folding component 3 is connected to the mounting frame 23, and can control the slider 22 of the mounting frame 23 to slide along the obtuse-angle sliding groove 21.

[0038] According to the above description, the photovoltaic device with closing protection function mainly includes a bottom plate 1, a mounting plate 2, a mounting frame 23, a protective shell 25 and a folding assembly 3. The two photovoltaic panels 24 are respectively fixed in the two mounting frames 23, and the bottom of the mounting frame 23 is covered and fixed with a protective shell 25, which can block the outside of the photovoltaic panel 24 to form protection when the mounting frame 23 is folded. An obtuse-angle sliding groove 21 is provided on the mounting plate 2 at the front and rear positions, and sliders 22 are respectively fixed on the two outer sides of the mounting frame 23, and the sliders 22 can slide in the obtuse-angle sliding groove 21. The upper part of the folding assembly 3 is connected to the mounting frame 23, and is mainly used to realize the opening and closing of the mounting frame 23. The folding component 3 lifts the mounting frame 23 upward, so that when the slider 22 is located at the top of the obtuse-angle sliding groove 21, the mounting frame 23 is horizontally set and in an open state, and the photovoltaic panel 24 is in a normal operation state; the folding component 3 pulls the mounting frame 23 downward, so that when the slider 22 is located at the bottom of the obtuse-angle sliding groove 21, the mounting frame 23 is vertically set and in a folded state, and the photovoltaic panel 24 is protected by the protective shell 25.

[0039] Specifically, the obtuse opening of the obtuse-angled sliding groove 21 faces outward, and the vertical groove at the bottom of the obtuse-angled sliding groove 21 is perpendicular to the bottom plate 1. When the folding component 3 drives the slider 22 to the top of the oblique groove at the top of the obtuse-angled sliding groove 21, the installation frame 23 is horizontally arranged and presents an open state; when the folding component 3 drives the slider 22 to the connection between the obtuse groove and the vertical groove of the obtuse-angled sliding groove 21, the installation frame 23 gradually flips upward from the horizontal position in the open state, folds to a vertical setting and presents a folded state; when the folding component 3 continues to drive the slider 22 to the bottom of the vertical groove at the bottom of the obtuse-angled sliding groove 21, the installation frame 23 no longer flips and continues to be vertically arranged.

[0040] Furthermore, the folding assembly 3 includes a mounting shell 31, a push rod 32, a transverse plate 33 and a hinge 34; the mounting shell 31 is fixed to the inner side of the mounting plate 2; a driving member is fixed to the inner bottom of the mounting shell 31; the upper part of the driving member is fixed to the push rod 32, and the upper part of the push rod 32 passes through the top of the mounting shell 31; the bottoms on both sides of the transverse plate 33 are respectively fixed to the top of a push rod 32; a plurality of hinges 34 are evenly spaced along both ends of the transverse plate 33; one end of the hinge 34 is fixed to the transverse plate 33, and the other end is fixed to the inner end of the mounting frame 23 located at the same end (i.e., the end close to the transverse plate 33).

[0041] According to the above description, if Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the folding assembly 3 mainly includes a mounting housing 31, a push rod 32, a cross plate 33 and a hinge 34. The two mounting housings 31 are disposed inside the two mounting plates 2. The driving member is fixed in the mounting housing 31 to provide power for the push rod 32; the two ends of the cross plate 33 are respectively fixed on the two push rods 32, and move up and down following the lifting and lowering of the push rods 32; the two ends of the hinge 34 are respectively fixed on the cross plate 33 and the mounting frame 23. Through the lifting and lowering of the push rod 32 and the guided sliding between the slider 22 and the obtuse-angle sliding groove 21, when the slider 22 moves downward along the obtuse-angle sliding groove 21, the mounting frame 23 can also be gradually turned upward synchronously around the rotating shaft of the hinge 34 while following the downward movement of the cross plate 33.

[0042] Specifically, when the installation frame 23 is folded, the driving member drives the push rod 32 to retract, thereby driving the horizontal plate 33 to move downward, and then the horizontal plate 33 drives the installation frame 23 to move downward together through the hinge 34; at this time, because the installation frame 23 is not only pulled down by the horizontal plate 33, but also guided by the obtuse angle sliding groove 21 due to the sliding of the slider 22 in the obtuse angle sliding groove 21, and is also hinged by the hinge 34, the installation frame 23 originally set horizontally gradually turns upward around the rotation axis of the hinge 34 while following the downward movement of the horizontal plate 33. When the slider 22 moves to the connection between the obtuse angle sliding groove 21 and the vertical groove, the installation frame 23 has turned upward 90° around the rotation axis of the hinge 34 and is in a vertically erected folded state. The horizontal plate 33 continues to drive the installation frame 23 to move downward through the hinge 34, and the slider 22 moves to the bottom along the vertical groove at the bottom of the obtuse sliding groove 21. During this process, the installation frame 23 remains in a vertically upright state and no longer turns over. The driving member drives the push rod 32 to extend, and the installation frame 23 is unfolded, thereby pushing the horizontal plate 33 and the installation frame 23 to reset.

[0043] Particularly, between the hinge 34 and the slider 22 at the same end, the hinge 34 is disposed close to the inner end of the mounting frame 23 .

[0044] Particularly, the plurality of hinges 34 are evenly spaced apart along the length direction of the transverse plate 33 .

[0045] Particularly, three hinges 34 are provided on the same set of folding components 3 .

[0046] In particular, the push rod 32 may be driven by a motor, or may be driven by a pneumatic cylinder, a hydraulic cylinder, or the like.

[0047] In particular, the driving member can be connected to various sensor electrical signals for detecting weather conditions. When the sensor detects the arrival of severe weather such as heavy rain, the driving member is automatically controlled to work, so as to realize the folding work of the folding assembly 3, protect the photovoltaic panel 24, and reduce the burden on the staff. When the severe weather subsides, the driving member is controlled to unfold the folding assembly 3, and the photovoltaic panel 24 resumes working state.

[0048] Furthermore, it also includes a closing component 4; the closing component 4 includes a column 41, a U-shaped sealing plate 42, a return spring 43 and an L-shaped fixing rod 44; the U-shaped sealing plate 42 is covered on the outer periphery of the mounting frame 23, and the inner wall of the U-shaped sealing plate 42 is arranged on the outer periphery of the protective shell 25; a plurality of the columns 41 are evenly spaced at the bottom of the mounting frame 23; the column 41 passes through the U-shaped sealing plate 42, and the end is fixed to the mounting frame 23; the return spring 43 is sleeved on the column 41, and its two ends are connected to the outer end of the column 41 , the outer side of the U-shaped sealing plate 42 is abutted; the U-shaped sealing plate 42 can slide along the column 41; the reset spring 43 provides elastic force to press the U-shaped sealing plate 42 toward the mounting frame 23; the front and rear ends of the top of the mounting plate 2 are respectively fixed with an L-shaped fixing rod 44 in a mirror-symmetrical manner; the lower part of the L-shaped fixing rod 44 is vertically arranged, and the bottom is fixed to the top of the mounting plate 2, and the upper part of the L-shaped fixing rod 44 is horizontally arranged toward the outside; the two outer side walls of the U-shaped sealing plate 42 are respectively fixed with obtuse-angled bevel strips 45 that cooperate with the L-shaped fixing rod 44 located at the same end.

[0049] According to the above description, if Figure 6 and Figure 7As shown, the closing assembly 4 is mainly used to close the gap between the two mounting frames 23 after the two mounting frames 23 are folded to prevent rainwater from leaking into the interior. The closing assembly 4 mainly includes a column 41, a U-shaped sealing plate 42, a return spring 43 and an L-shaped fixing rod 44. The U-shaped sealing plate 42 is covered on the outer periphery of the mounting frame 23 and is arranged close to the outer periphery of the protective shell 25, and together with the protective shell 25, it forms a protection for the mounting frame 23 (and the photovoltaic panel 24 in the mounting frame 23); the U-shaped sealing plate 42 can slide along the column 41, and the return spring 43 on the column 41 presses the U-shaped sealing plate 42 toward the mounting frame 23, so that when the mounting frame 23 is folded, the ends of the two U-shaped sealing plates 42 close to each other can fit tightly to reduce rainwater leakage; obtuse-angled bevel strips 45 that cooperate with the L-shaped fixing rod 44 located at the same end are respectively fixed on the two outer side walls of the U-shaped sealing plate 42, and the obtuse-angled bevel strips 45 and the L-shaped fixing rod 44 are guided by the cooperation, so that the two U-shaped sealing plates 42 can be moved from spacing to proximity and then to compression.

[0050] Specifically, the obtuse angled strip 45 opens upward, and the horizontal side of the outer side of the obtuse angled strip 45 is parallel to the bottom plate 1. When the slider 22 moves to the connection between the obtuse angled slot and the vertical slot of the obtuse angled sliding slot 21, the mounting frame 23 has been turned upward 90° around the rotation axis of the hinge 34 and is in a vertically erected folded state, and the U-shaped sealing plate 42 is also in an upright state. Since the mounting frame 23 is connected to the cross plate 33 through the hinge 34, and the cross plate 33 must have a certain width, when the two mounting frames 23 are both in a vertically erected state, there must be a certain gap between the two mounting frames 23, and they cannot be completely closed together. At the same time, when the slider 22 is at the connection between the obtuse angled slot and the vertical slot of the obtuse angled sliding slot 21, the upper part of the L-shaped fixing rod 44 begins to contact the outer wall surface of the inner hypotenuse of the obtuse angled strip 45. The horizontal plate 33 continues to drive the installation frame 23 to move downward through the hinge 34. During the process of the slider 22 moving to the bottom along the vertical groove at the lower part of the obtuse-angled sliding groove 21, the L-shaped fixing rod 44 continues to contact the obtuse-angled beveled edge of the obtuse-angled beveled edge 45, and through the guiding effect of the obtuse-angled beveled edge of the obtuse-angled beveled edge 45, the two U-shaped sealing plates 42 are pushed closer to each other. When the slider 22 moves to the bottom of the vertical groove of the obtuse angle sliding groove 21, the vertical side of the obtuse angled strip 45 (the horizontal side of the obtuse angled strip 45 of the U-shaped sealing plate 42 in the horizontal state, after the U-shaped sealing plate 42 turns upward 90° to become a vertical state, the horizontal side of the obtuse angled strip 45 naturally becomes vertical, so it is described as the vertical side of the obtuse angled strip 45) conflicts with the upper part of the L-shaped fixing rod 44. At this time, the two U-shaped sealing plates 42 are already tightly fitted to each other and are kept pressed together under the guidance of the vertical side of the obtuse angled strip 45. At this time, the reset springs 43 are all compressed, and the two U-shaped sealing plates 42 seal the gap between the two installation frames 23 to prevent rainwater leakage. The driving member drives the push rod 32 to extend, and the installation frame 23 is unfolded, and the two U-shaped sealing plates 42 are gradually separated and reset under the reset action of the reset spring 43.

[0051] In particular, the length of the vertical groove of the obtuse-angled sliding groove 21 should be greater than the length of the hypotenuse of the obtuse-angled bevel strip 45, but less than the sum of the horizontal side and the hypotenuse of the obtuse-angled bevel strip 45, so as to ensure that the two U-shaped sealing plates 42 can be pressed tightly.

[0052] Particularly, in the same set of closing components 4 , four upright posts 41 are provided, and the upright posts 41 are located on the two outer sides (ie, short sides) of the mounting frame 23 .

[0053] In particular, a rubber sealing pad can be provided on the top of the U-shaped sealing plate 42 , which can improve the sealing performance on the one hand, and also play a buffering role on the other hand, reducing the rigid collision between the two U-shaped sealing plates 42 and increasing the service life of the U-shaped sealing plate 42 .

[0054] Furthermore, it also includes a flushing component 5; the flushing component 5 includes a water tank 51, a water pump 52, a water inlet pipe 53, a water outlet pipe 54, a circular pipe 55, a connecting pipe 56 and a flushing pipe 57; the water tank 51 is fixed on the base plate 1; the water pump 52 is fixed on the outside of the water tank 51, and both ends of the water inlet pipe 53 connect the water pump 52 and the water tank 51; the circular pipe 55 is fixed at the bottom of the folding component 3; the upper part of the circular pipe 55 is connected to the water pump 52 through the water outlet pipe 54, and the lower part of the circular pipe 55 is connected to one end of two connecting pipes 56; the other ends of the two connecting pipes 56 respectively penetrate into the interior of the folding component 3, and are connected to the flushing pipe 57 fixed on the bottom of the inner periphery of the folding component 3; the flushing pipe 57 is evenly spaced and connected to multiple nozzles.

[0055] According to the above description, if Figure 8 As shown, the flushing assembly 5 mainly includes a water tank 51, a water pump 52, an inlet pipe 53, an outlet pipe 54, a round pipe 55, a connecting pipe 56 and a flushing pipe 57. After the photovoltaic panel 24 has been used for a period of time, various dirt and impurities such as sand or solidified salt may be attached to its surface. At this time, the water pump 52 is started, and the water in the water tank 51 is pumped to the flushing pipe 57 through the inlet pipe 53, the outlet pipe 54, the round pipe 55 and the connecting pipe 56, and sprayed from the nozzle set on the flushing pipe 57, so as to flush the photovoltaic panel 24. Since the two photovoltaic panels 24 need to be flipped upward to a vertical state for storage, the flushing pipe 57 and the connecting pipe 56 are set at the horizontal plate 33, which is convenient for centralized installation and later maintenance of the flushing pipe 57 and the connecting pipe 56. When the two photovoltaic panels 24 are in a horizontally unfolded state, the two flushing pipes 57 flush the two photovoltaic panels 24 respectively, and one flushing pipe 57 only needs to flush the surface of one photovoltaic panel 24, so that the flushing area is smaller, thereby flushing the surface of the photovoltaic panel 24 more cleanly. In heavy rain weather, the flushing pipe 57 is also protected between the two mounting frames 23, so that the heavy rain can prevent the flushing pipe 57 and the nozzles arranged thereon from being affected.

[0056] Particularly, the round tube 55 is fixed at the middle of the bottom of the inner end of the transverse plate 33 .

[0057] Particularly, the bottom of the circular tube 55 is closed.

[0058] Furthermore, it also includes a collecting component 6; the collecting component 6 includes a U-shaped baffle 62, a pull rope 63, a piston circular plate 64 and a collecting pipe 66; a groove 61 is opened on the upper part of the outer end of the mounting frame 23 (i.e., the end away from the horizontal plate 33); the U-shaped baffle 62 is slidably arranged in the groove 61; the piston circular plate 64 is slidably arranged in the circular tube 55; one end of the pull rope 63 is fixed to the middle part of the outer side of the U-shaped baffle 62, and the other end is fixed to the piston circular plate 64 after passing through the circular tube 55; the piston circular plate 64 is located between the water outlet pipe 54 and the connecting pipe 56; the piston circular plate 64 separates the inside of the circular tube 55; a drainage channel 65 is opened on one side of the mounting frame 23; one end of the drainage channel 65 is connected to the groove 61, and the other end is connected to the collecting pipe 66; the other end of the collecting pipe 66 is connected to the water tank 51.

[0059] According to the above description, if Fig. 9 , Fig.10 ,and Fig.11 As shown, in the unfolded state, initially, the U-shaped baffle 62 is located at the bottom of the groove 61 provided on the mounting frame 23 under the action of its own gravity. When it rains lightly, since the energy carried by the rainwater in the light rain is small, it will not cause much damage to the photovoltaic panels 24, so the two photovoltaic panels 24 are still in the unfolded state. At this time, the rainwater can be collected by the groove 61 provided on the mounting frame 23, and the rainwater in the groove 61 enters the collection pipe 66 through the drainage channel 65, and finally is injected into the water tank 51 through the collection pipe 66. In this way, the flushing water in the water tank 51 can be supplemented, avoiding the staff from frequently replenishing the water tank 51. When the surface of the photovoltaic panel 24 needs to be flushed, the water pump 52 injects flushing water into the circular tube 55 through the outlet pipe 54. Since the initial height of the piston circular plate 64 is located between the heights of the circular tube 55 and the connection pipe 56, the circular tube 55 is divided into two parts, the upper and lower parts. Therefore, the flushing water injected into the circular tube 55 will first press the piston circular plate 64 downward before flowing into the connection pipe 56. When the piston circular plate 64 moves downward, the U-shaped baffle 62 will be pulled up to a position flush with the upper surface of the installation frame 23 through the pull rope 63, thereby closing the groove 61 set on the installation frame 23, so as to prevent the flushed sewage flowing through the surface of the photovoltaic panel 24 from flowing into the groove 61, thereby preventing the sewage from flowing into the water tank 51. After flushing is completed, the piston disc 64 loses the pressure of the flushing water, and the U-shaped baffle 62 moves downward to reset under the action of its own gravity, and the piston disc 64 is also pulled upward by the pull rope 63 to reset, thereby unlocking the U-shaped baffle 62 to close the groove 61.

[0060] Furthermore, it also includes a cleaning component; the cleaning component includes a clamping seat 71 and a brush 72; a connecting plate 35 is fixed between the front ends and between the rear ends of the two mounting shells 31; the two clamping seats 71 are fixed to the bottom of the connecting plate 35; the brush 72 is clamped and arranged between the two clamping seats 71 located on the same connecting plate 35.

[0061] According to the above description, if Fig.12 As shown, when there are impurities attached to the photovoltaic panel 24 that cannot be washed away by the flushing pipe 57, the staff can remove the brush 72 from the clamping seat 71 and brush these impurities in conjunction with the flushing of the flushing pipe 57.

[0062] Furthermore, it also includes a drainage component; the drainage component includes a drain port 81 that runs horizontally through the middle of the mounting plate 2; the drain port 81 is arranged close to the folding component 3; a shielding frame 82 is fixed to the outside of the mounting plate 2; the bottom of the shielding frame 82 is open, and the inner side is connected to the drain port 81.

[0063] According to the above description, if Fig.13 As shown, in the process of the installation frame 23 turning upward and the U-shaped sealing plates 42 approaching each other, some rainwater will inevitably fall into and gather in the internal space surrounded by the installation plate 2, the horizontal plate 33 and the installation frame 23, and the gap formed by the installation frame 23 and the horizontal plate 33 due to the hinge 34 is not enough to quickly drain the rainwater. At this time, by setting the drain port 81, the rainwater can be quickly discharged from the drain port 81. At the same time, the shielding frame 82 blocks the outside of the drain port 81, so that the rainwater falling from the outside cannot affect the draining process of the drain port 81, and will not enter the internal space from the drain port 81.

[0064] Particularly, the bottom of the drain port 81 is disposed close to the top of the horizontal plate 33 .

[0065] Furthermore, the protective shell 25 is a wedge-shaped structure with a small outside and a large inside, and a plurality of guide grooves are provided on the outer surface of the protective shell 25. After being folded, the protective shell 25 becomes a triangular shell structure, and when a strong horizontal wind blows onto the protective shell 25 during rain, the guide grooves provided on the protective shell 25 can guide the wind obliquely upward or obliquely outward, thereby preventing the entire device from being blown down by the strong wind.

Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
