Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a photovoltaic bracket. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect at the interface of semiconductors to directly convert sunlight into electrical energy. It primarily consists of three main components: solar panels (modules), a controller, and an inverter. Conventional photovoltaic panels are typically secured outdoors using brackets. These brackets are fixed metal frames that tilt the panels to a specific angle, ensuring they receive the most direct sunlight, thereby improving power generation efficiency.

[0003] In the existing technology, the brackets for installing photovoltaic panels are generally standard installations, and their function is only to simply adjust the offset angle of the photovoltaic panels. However, after long-term use, a lot of dust will adhere to the surface of the photovoltaic panels, and when there is a lot of dust, it is easy to affect the power generation efficiency of the photovoltaic panels. If manual cleaning is used, although the corresponding cleaning can be completed, the height of the photovoltaic panels is generally relatively high, which will also pose corresponding safety hazards.

[0004] Therefore, the existing demand is not met, and we propose a photovoltaic bracket. Summary of the Invention

[0005] The present invention provides a photovoltaic bracket, which can not only complete the cleaning of the surface of the photovoltaic panel through the setting of the cleaning component, but also because a first slide groove is opened on the installation base plate and a plurality of limit blocks are arranged inside the second slide groove, the cleaning component will also make contact between the first connecting rod and the plurality of limit blocks during the movement, thereby allowing the corresponding cleaning rollers to move back and forth left and right during the movement, so as to further improve the cleaning efficiency of the cleaning component for the photovoltaic panel, solving the problem mentioned in the above background technology that if manual cleaning is adopted, although the corresponding cleaning can be completed, the height of the photovoltaic panel is generally relatively high, which will also pose corresponding safety hazards.

[0006] The present invention provides the following technical solution: a photovoltaic bracket, comprising a mounting base plate, wherein a cleaning component for cleaning a photovoltaic panel is provided on the mounting base plate; The mounting base is respectively provided with a first slide groove and a second slide groove, and the two ends of the positioning base are respectively arranged on two connecting rotating plates, and the two connecting rotating plates are both connected with a first connecting rod, and the two first connecting rods are respectively slidably arranged inside the first slide groove and the second slide groove.

[0007] As an optional solution of the photovoltaic bracket described in the present invention, wherein: the mounting base is installed on the bracket seat, and the cleaning assembly is composed of a cleaning roller, a positioning base and a cleaning nozzle; The cleaning roller is slidably arranged inside the positioning base, a connecting spring is further arranged between the cleaning roller and the positioning base, an accommodating cavity is opened inside the cleaning roller, and a positioning arc plate and a water storage bag are arranged inside the accommodating cavity.

[0008] As an optional solution for a photovoltaic bracket described in the present invention, there is a fixed connection between the positioning arc plate and the water storage bag, the top of the positioning arc plate is fixedly connected to one end of the third connecting rod, and the other end of the third connecting rod is fixedly connected to the positioning base.

[0009] As an optional solution for a photovoltaic bracket described in the present invention, several groups of connecting grooves are provided at the bottom of the cleaning roller, a spiral groove is provided inside each of the connecting grooves, and a connecting base is provided inside each of the connecting grooves.

[0010] As an optional solution for a photovoltaic bracket described in the present invention, wherein: a connecting ball is provided on the outer surface of the connecting base, the connecting ball is slidingly arranged inside the spiral groove, and the top of the connecting base forms a rotating connection with one end of the connecting water pipe.

[0011] As an optional solution for a photovoltaic bracket described in the present invention, the other end of the connecting water pipe is fixedly mounted on the positioning base, a water storage chamber is provided inside the connecting base, the connecting water pipe is communicated with the water storage chamber, and the bottom end of the connecting water pipe is also fixedly connected to a first bevel gear.

[0012] As an optional solution for a photovoltaic bracket described in the present invention, a rotating connecting rod is further provided inside the connecting base through a torsion spring, a second bevel gear is installed on the rotating connecting rod, and the second bevel gear and the rotating connecting rod are engaged with each other.

[0013] As an optional solution for a photovoltaic bracket described in the present invention, one end of a connecting piece is installed on the rotating connecting rod, and the other end of the connecting piece is fixedly connected to the cleaning nozzle, and the cleaning nozzle is also connected to the inside of the water storage chamber through a connecting hose.

[0014] As an optional solution of the photovoltaic bracket described in the present invention, a third sliding groove is opened inside the first sliding groove.

[0015] As an optional solution for a photovoltaic bracket described in the present invention, a plurality of limit blocks for changing the moving trajectory of the cleaning component are arranged inside the third slide groove.

[0016] The present invention has the following beneficial effects:

[0017] 1. The photovoltaic bracket is provided with a cleaning component. When the user needs to clean the photovoltaic panel, he only needs to move the cleaning component provided at the top end of the photovoltaic panel. When the cleaning component provided at the top end of the photovoltaic panel moves, not only can the surface of the photovoltaic panel be cleaned, but also because a first slide groove is provided on the mounting base plate and a plurality of limit blocks are provided inside the second slide groove, during the movement of the cleaning component, the contact between the first connecting rod and the plurality of limit blocks will be used, thereby allowing the corresponding cleaning roller to move back and forth left and right during the movement, thereby further improving the cleaning efficiency of the cleaning component for the photovoltaic panel.

[0018] 2. The photovoltaic bracket is provided with a water storage bag and a cleaning nozzle inside the cleaning roller. Therefore, when the cleaning roller moves to clean the photovoltaic panel, if it encounters hard protrusions such as bird droppings, the cleaning roller will move toward the positioning base. At this time, the cleaning roller will not only squeeze the water storage bag, so that the water stored in the water storage bag is transported to the corresponding cleaning nozzle, and then the spiral groove surface is flushed through the cleaning nozzle. In addition, during the upward movement of the cleaning roller, the connecting base and the cleaning nozzle arranged inside the connecting base will also be driven to rotate, so as to increase the spraying range of the cleaning nozzle on the photovoltaic panel, and the rotation of the connecting base will also make the cleaning nozzle swing back and forth, thereby further improving the cleaning effect of the cleaning nozzle on the photovoltaic panel.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0029] For example 1, please refer to Figures 1-8 A photovoltaic support includes a support base 1, on which a mounting base 101 for mounting a photovoltaic panel 104 is mounted. Figure 1 It can be seen that a hydraulic rod is provided on the bracket seat 1 for adjusting the angle of the mounting base 101. Therefore, when the user fixes the bracket seat 1 in the specified position, the hydraulic rod can be used to adjust the optimal angle of the mounting base 101, so that after the photovoltaic panel 104 is installed, the photovoltaic panel 104 can work in real time. It should be noted that the use of the extension and retraction of the hydraulic rod to adjust the angle of the mounting base 101 is an existing technology commonly used by people in this field. Users can adjust it according to actual conditions and their own needs, and will not be elaborated here.

[0030] See Figure 1 It can be seen that a cleaning component 2 for cleaning the photovoltaic panel 104 is also provided on the mounting base 101. The cleaning component 2 is arranged on the top of the photovoltaic panel 104, and a connection is formed between the first connecting rod 204 in the cleaning component 2 arranged on the top of the photovoltaic panel 104 and the output end of the external hydraulic rod. The external hydraulic rod is arranged on the top of the mounting base 101. Therefore, when the user needs to clean the photovoltaic panel 104, he only needs to start the external hydraulic rod, and the external hydraulic rod will lead the first connecting rod 204 to move accordingly.

[0031] See Figure 1It can be seen that a first sliding groove 102 is provided on the inner wall of the mounting base 101. Figure 4 It can be seen that a third slide groove 105 is opened on the inner wall of the first slide groove 102, and the first connecting rod 204 is slidably set inside the third slide groove 105. It should be noted that since the output end of the external hydraulic rod is connected to the first connecting rod 204 through a sleeve, this arrangement not only allows the first connecting rod 204 to follow the extension or retraction of the external hydraulic rod, thereby sliding accordingly inside the third slide groove 105, but also does not affect the movement effect of the first connecting rod 204 when the first connecting rod 204 moves in the left and right directions subsequently.

[0032] See Figure 4 It can be seen that a plurality of limiting movement grooves 106 are further provided inside the third chute 105, and the limiting movement grooves 106 are arranged equidistantly. Therefore, when the first connecting rod 204 slides inside the third chute 105, the first connecting rod 204 will be squeezed by the plurality of limiting movement grooves 106 in sequence, so that the first connecting rod 204 can move Figure 4 It should be noted that, since the other end of the first connecting rod 204 is mounted on the connecting rotating plate 203, and the connecting rotating plate 203 is respectively mounted with the cleaning roller 201 and the positioning base 202, when the first connecting rod 204 moves, the entire cleaning assembly 2 will be moved to the right. Figure 4 That is, as the cleaning component 2 moves along the photovoltaic panel 104 and completes the cleaning of dust and impurities on the surface of the photovoltaic panel 104, it will also move back and forth left and right on the photovoltaic panel 104.

[0033] It should be noted that the first connecting rod 204 slidingly arranged inside the third sliding groove 105 is slidingly arranged inside the limiting movable groove 106 through a ball. This arrangement not only allows the first connecting rod 204 to be squeezed and restricted by the limiting movable groove 106 during movement, thereby moving back and forth in the left and right directions, but also prevents the first connecting rod 204 from being unable to reset after being squeezed, thereby affecting the subsequent movement effect of the first connecting rod 204.

[0034] It should be noted that the connecting rotating plate 203 connecting the cleaning roller 201 and the other end of the positioning base 202 is also slidably set inside the second slide groove 103 through the first connecting rod 204. Therefore, when the first connecting rod 204 slidingly set inside the third slide groove 105 moves, the first connecting rod 204 set inside the second slide groove 103 will also move synchronously, thereby avoiding the occurrence of jamming.

[0035] It should be noted that corresponding cleaning bristles can also be provided on the bottom surface of the cleaning roller 201. This arrangement not only allows the cleaning component 2 to complete the cleaning effect of the surface of the photovoltaic panel 104 during the movement, but also allows the cleaning component 2 to move left and right during the movement to complete the further cleaning effect of the corners of the photovoltaic panel 104, thereby effectively improving the cleaning effect of the photovoltaic panel 104.

[0036] At the same time, since the cleaning nozzle 219 in the cleaning component 2 will spray the photovoltaic panel 104 during the subsequent movement process, the above-mentioned movement method can also effectively change the spray range of the cleaning nozzle 219 on the photovoltaic panel 104, thereby further improving the cleaning effect of the cleaning nozzle 219 on the photovoltaic panel 104.

[0037] The second embodiment is intended to promote the solution of the problem that when the photovoltaic panel 104 is set in the outside world, it is inevitable that debris such as mud or bird droppings will adhere to it. If the mud or bird droppings and other debris are dried and hardened, a certain degree of protrusions will appear on the surface of the photovoltaic panel 104. At this time, if the cleaning roller 201 is moved for cleaning, it is inevitable that it will come into contact with these hard protrusions. If the cleaning roller 201 is directly moved for contact, it is very likely to damage the surface of the photovoltaic panel 104. This embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figures 1-8 On the one hand, see Figure 5 215 , and the cleaning roller 201 is provided with a plurality of connecting grooves 215 on the bottom surface thereof, and a cleaning nozzle 219 is provided inside each connecting groove 215 . Therefore, when the cleaning roller 201 encounters dry and hard mud or bird droppings during the cleaning process, the cleaning roller 201 will slide on the positioning base 202 , and thus move closer to the positioning base 202 at the moment of contact with the dry and hard mud or bird droppings. This arrangement can also effectively prevent the cleaning roller 201 from coming into close contact with the dry and hard mud or bird droppings, which may cause damage to the photovoltaic panel 104. It should be noted that a connecting spring 210 is provided between the cleaning roller 201 and the positioning base 202 . Therefore, after the cleaning roller 201 moves closer to the center position of the cleaning roller 201 , it can also be effectively reset accordingly by the reset elastic force of the connecting spring 210 , so that in the subsequent movement, the cleaning roller 201 can continue to clean the photovoltaic panel 104 . On the other hand, see Figure 5It can be seen that an accommodating chamber 208 is provided inside the cleaning roller 201, and a positioning arc plate 209 and a water storage bag 216 are provided inside the accommodating chamber 208. The positioning arc plate 209 and the water storage bag 216 are fixedly connected. The top of the positioning arc plate 209 is fixedly connected to one end of the third connecting rod 211, and the other end of the third connecting rod 211 is fixedly connected to the positioning base 202. Through this arrangement, when the cleaning roller 201 moves close to the positioning base 202, the water storage bag 216 fixedly provided inside the accommodating chamber 208 will be squeezed by the cleaning roller 201. Because the water storage bag 216 is connected to the connecting water pipe 212, and the other end of the connecting water pipe 212 is connected to the connecting base 213 connected to the cleaning nozzle 219, that is to say, when the water storage bag 216 is squeezed by the cleaning roller 201, the water stored in the water storage bag 216 will be squeezed by the cleaning roller 201. The water source inside the water storage bag 216 will be injected into the connecting base 213 through the connecting water pipe 212, and complete the water supply effect of the cleaning nozzle 219, so that the surface of the photovoltaic panel 104 can be cleaned through the cleaning nozzle 219. This spraying can not only soften the dry and hard mud or bird droppings, but also allow the cleaning roller 201 to effectively clean the softened mud or bird droppings during the subsequent resetting process, so as to avoid the cleaning roller 201 from coming into close contact with the dry and hard mud or bird droppings during the moving cleaning process, which may cause damage to the photovoltaic panel 104. In addition, using the cleaning nozzle 219 to spray the photovoltaic panel 104 can also further improve the cleaning degree of the cleaning roller 201 on the photovoltaic panel 104, thereby effectively improving the cleaning efficiency of the photovoltaic panel 104.

[0038] It should be noted that a water storage chamber 220 is provided inside the connecting base 213, and the connecting water pipe 212 is connected to the water storage chamber 220, and the connecting base 213 and the connecting water pipe 212 are in a rotating connection. Therefore, even if the connecting base 213 rotates, it will not affect the water supply effect of the connecting water pipe 212 to the inside of the water storage chamber 220. Because the water storage chamber 220 is connected to the cleaning nozzle 219 through a connecting hose, that is to say, when the connecting base 213 rotates, the water storage chamber 220 and the cleaning nozzle 219 are relatively stationary. Through this arrangement, the water supply to the inside of the cleaning nozzle 219 can be effectively guaranteed.

[0039] See Figure 8It can be seen that a spiral groove 214 is provided inside each connecting groove 215, and the outer surface of the connecting base 213 is slidably set inside the spiral groove 214 through the connecting ball 217. Therefore, when the cleaning roller 201 moves close to the positioning base 202, the connecting base 213 originally set inside the connecting groove 215 will gradually extend out of the connecting groove 215, and through the limited sliding of the connecting base 213 and the spiral groove 214, the connecting base 213 can also rotate accordingly on the connecting water pipe 212 during the extension process. That is to say, the cleaning nozzle 219 rotates while spraying. Therefore, this setting further improves the spraying range of the cleaning nozzle 219 on the photovoltaic panel 104, thereby improving the cleaning efficiency of the photovoltaic panel 104.

[0040] The bottom end of the connecting water pipe 212 is also fixedly connected to a first bevel gear 223, and a rotating connecting rod 221 is rotatably provided inside the connecting base 213, and a second bevel gear 224 is fixedly installed on the rotating connecting rod 221, and the first bevel gear 223 and the second bevel gear 224 are meshed with each other. Therefore, when the connecting base 213 rotates inside the spiral groove 214 through the connecting ball 217, the connecting base 213 also rotates with the connecting water pipe 212 as the center. Therefore, the second bevel gear 224 will also rotate synchronously around the first bevel gear 223, thereby driving the rotating connecting rod 221 to perform a corresponding rotation effect.

[0041] Since one end of the connecting member 222 is fixedly installed on the rotating connecting rod 221, and the other end of the connecting member 222 is installed on the cleaning nozzle 219, when the rotating connecting rod 221 rotates, the cleaning nozzle 219 will also be driven to rotate accordingly. By rotating the cleaning nozzle 219, the spraying angle of the cleaning nozzle 219 is also changed, thereby further improving the spraying range of the cleaning nozzle 219 on the photovoltaic panel 104, thereby effectively improving the cleaning efficiency of the cleaning nozzle 219 on the photovoltaic panel 104.

[0042] Since the connecting base 213 rotates more than one circle, that is to say, the rotation of the above-mentioned rotating connecting rod 221 also rotates more than one circle, if this rotation is performed, the cleaning nozzle 219 will be stuck. The teeth provided on the first bevel gear 223 are intermittently provided. Therefore, when the second bevel gear 224 meshes and rotates around the first bevel gear 223, it can only be performed when the teeth of the two are meshed with each other. When the second bevel gear 224 rotates to the part where the first bevel gear 223 is not provided with teeth, the second bevel gear 224 will not rotate. In addition, because the rotating connecting rod 221 is rotatably provided inside the connecting base 213 by a torsion spring, it should be noted that there is a torsion spring between one end of the torsion spring and the connecting base 213. The second bevel gear 224 is fixedly connected, and the other end of the torsion spring is fixedly connected to the rotating link 221. Therefore, when the second bevel gear 224 stops rotating, the rotating link 221 will be affected by the reset elastic force of the torsion spring, so that it rotates in the opposite direction, thereby driving the cleaning nozzle 219 to rotate in the opposite direction. This arrangement can effectively avoid the cleaning nozzle 219 from getting stuck due to excessive rotation, and because the teeth on the first bevel gear 223 are intermittently arranged, the rotation and reset of the above-mentioned cleaning nozzle 219 will also be reciprocating. By utilizing this reciprocating swing, the spraying range of the cleaning nozzle 219 on the photovoltaic panel 104 can be further improved, thereby effectively improving the cleaning efficiency of the photovoltaic panel 104.

[0043] It should be noted that, see Figure 1 It can be seen that a corresponding slide groove is provided on the side wall of the mounting base 101, and a water supply pipe is slidingly arranged inside the slide groove. The water supply pipe is connected to the corresponding water storage bag 216. Therefore, when the cleaning component 2 moves, the water supply pipe can also slide synchronously. This setting is to ensure that after the cleaning roller 201 releases the squeeze on the water storage bag 216, a certain amount of water will always be stored inside the water storage bag 216, so that the next time it encounters hard protrusions such as bird droppings, the water storage bag 216 can still provide corresponding water supply to the cleaning nozzle 219.

[0044] At the same time, when the cleaning component 2 arranged at the top end of the mounting base plate 101 is moved to the bottom of the photovoltaic panel 104 by the squeezing of the hydraulic rod, the first cleaning of the photovoltaic panel 104 by the cleaning component 2 is also completed. At this time, the user can control the external hydraulic rod to drive the cleaning component 2 arranged at the top end of the photovoltaic panel 104 to complete the corresponding reset. Because the cleaning of the cleaning component 2 is mainly based on the contact and squeezing between the limiting movable groove 106 and the first connecting rod 204, the cleaning component 2 will also contact several limiting movable grooves 106 again during the reset process. That is to say, the cleaning component 2 can still perform corresponding secondary cleaning of the photovoltaic panel 104 during the reset process. Therefore, this setting can also further improve the cleaning effect of the cleaning component 2 on the photovoltaic panel 104.

[0045] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
