Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of photovoltaic supports, and particularly relates to a photovoltaic support for a photovoltaic shelter. BACKGROUND

[0002] As an integrated and rapidly deployable mobile energy solution, the photovoltaic shelter plays an important role in the fields of emergency communication, field operation, power supply in remote areas, etc. The photovoltaic support is a key component of the photovoltaic shelter system, which mainly provides stable support for the photovoltaic panel and adjusts the inclination angle to adapt to the sunlight angle at different times and in different seasons, so as to maximize the photovoltaic power generation efficiency. At present, the simplest photovoltaic support on the market is mostly of a fixed structure, and the angle cannot be changed after installation, which leads to low power generation efficiency when the light angle changes and cannot fully exert the performance of the photovoltaic panel.

[0003] In order to solve the efficiency problem of the fixed support, the existing technology has developed an angle-adjustable photovoltaic support, which is mainly divided into two categories: electric adjustment and manual adjustment. Although the electric adjustment support can realize automatic tracking, its structure is complex and must be equipped with a series of electric control devices such as motors, reducers, sensors and controllers. These precise electric control devices are exposed to outdoor wind, rain, snow and dust environment for a long time, so the failure rate is high and the maintenance cost is expensive. Especially, the driving motor needs to maintain torque for a long time when maintaining the angle of the photovoltaic panel, which is easy to cause fatigue damage and increase energy consumption, which is contrary to the original intention of pursuing high reliability and low maintenance of the photovoltaic shelter.

[0004] On the other hand, although the existing manual adjustment support has a relatively simple structure, it is inconvenient to operate. The adjustment mechanism of many manual supports is arranged on the top of the shelter, and the maintenance personnel need to climb to a high place to operate, which is not only time-consuming and laborious, but also has serious safety hazards in bad weather or when the shelter is placed high. In addition, whether it is an electric or a manual support, the cleaning problem of the photovoltaic panel is generally ignored. The dust, bird droppings and other pollutants accumulated on the surface of the photovoltaic panel can seriously block the sunlight, resulting in a significant decrease in power generation efficiency. The existing solution relies on manual cleaning, which also brings high labor cost and safety risk, and the cleaning cycle is difficult to guarantee. Therefore, how to provide a photovoltaic support which is convenient to operate, stable and reliable in structure and can solve the cleaning problem is a technical problem to be solved in the field. SUMMARY

[0005] The purpose of the present application is to provide a photovoltaic support for a photovoltaic shelter to solve the problems raised in the background.

[0006] In order to achieve the above object, the present application provides the following technical scheme: a photovoltaic support for a photovoltaic shelter, comprising a base, limit guide rails are installed at the front and rear ends of the base, longitudinal guide rails are installed at the left and right sides of the middle part of the base, a control assembly is movably connected to the inner side of the longitudinal guide rail, a longitudinal mounting block is installed at the top end of the control assembly, a self-cleaning assembly is arranged above the longitudinal mounting block, the left and right sides of the bottom end of the self-cleaning assembly are connected to the two longitudinal guide rails, support assemblies are installed at the front and rear ends of the longitudinal mounting block, and the ends of the support assemblies away from the longitudinal mounting block are movably connected to the limit guide rails.

[0007] The control assembly is used for adjusting the height of the longitudinal mounting block, and the support assemblies are driven to adjust the angle in linkage, when the longitudinal mounting block rises to the highest point, the self-cleaning assembly is triggered to clean the surface of the photovoltaic panel of the support assembly.

[0008] Before the photovoltaic panel is installed, the device is installed at the top end of the photovoltaic shelter, the bottom end of the control assembly is inserted through the roof of the photovoltaic shelter, the control assembly can be operated in the shelter, and the top end of the self-cleaning assembly is connected to the external water pump to ensure the normal supply of water flow.

[0009] As a further technical scheme of the present application, the control assembly comprises a longitudinal guide block, the left and right ends of the longitudinal guide block are movably connected to the two longitudinal guide rails, the longitudinal guide block is displaced up and down relative to the longitudinal guide rail, the left and right sides of the top end of the longitudinal guide block are provided with extension rods, and the ends of the extension rods away from the longitudinal guide block are connected to the bottom end of the longitudinal mounting block.

[0010] As a further technical scheme of the present application, a threaded groove is formed in the middle part of the longitudinal guide block, and a screw rod is threadedly connected to the threaded groove, the bottom end of the screw rod penetrates through the middle part of the bottom end of the base and is movably connected to the base, the screw rod rotates relative to the base, and a rotating disc is installed at the bottom end of the screw rod.

[0011] When the deflection angle of the double-sided photovoltaic panel needs to be adaptively adjusted, the rotating disc is rotated, the screw rod is rotated at this time, the longitudinal guide block is driven to displace up and down relative to the longitudinal guide rail under the guidance of the longitudinal guide block and the longitudinal guide rail at this time, and the longitudinal guide block drives the longitudinal mounting block to displace up and down through the extension rod at this time.

[0012] As a further technical scheme of the present application, the support assembly comprises a first fixing seat, one end of the first fixing seat is connected to the end surface of the longitudinal mounting block, a connecting rod is movably connected to the first fixing seat through a rotating shaft at the end away from the longitudinal mounting block, and a second fixing seat is movably connected to the connecting rod through a rotating shaft at the end away from the first fixing seat.

[0013] As a further technical scheme of the present application, the bottom end of the second fixing seat is movably connected with the limiting guide rail, the second fixing seat moves forward and backward relative to the limiting guide rail, the bottom end of the second fixing seat movably installs a guide block, and the outer side surface of the guide block is in contact with the inner bottom wall of the limiting guide rail.

[0014] As a further technical scheme of the present application, the inside of the connecting rod is provided with a clamping groove, the upper and lower ends inside the clamping groove are symmetrically movably connected with adjusting blocks, one side of the adjusting block movably installs a locking bolt, and the adjusting block is locked through the locking bolt and the clamping groove.

[0015] As a further technical scheme of the present application, the front surface of the adjusting block installs a photovoltaic mounting plate, and the photovoltaic mounting plate is fixed with the external photovoltaic panel through a bolt.

[0016] In the installation of the photovoltaic panel, the back surface of the photovoltaic panel is fixed with the photovoltaic mounting plate through a bolt, and the relative position of the photovoltaic mounting plate can be adjusted according to the area of the photovoltaic panel, that is, the locking bolt is loosened, the adjusting block is displaced relative to the clamping groove, and the position of the photovoltaic mounting plate relative to the clamping groove is adjusted, so that the two photovoltaic mounting plates can be fixed with the upper and lower ends of the back surface of the photovoltaic panel, and the fixing process of the photovoltaic panel is completed.

[0017] When the longitudinal mounting block moves up and down, the first fixing seat moves up and down at the same time, the connecting rod is driven to swing, and the second fixing seat at the bottom end moves forward and backward relative to the limiting guide rail, and the guide block rolls relative to the limiting guide rail, when the connecting rod rotates, the angle between the connecting rod and the limiting guide rail changes, the angle of the photovoltaic panel in front of the photovoltaic mounting plate changes, to adapt to different light angles, and improve the photovoltaic power generation efficiency.

[0018] By utilizing the cooperation between the operating assembly and the support assembly, the angle of the photovoltaic panels on the front and back sides can be adjusted at the same time by directly operating the operating assembly in the room and cooperating with the support assembly, the whole adjustment process can be quickly completed in the room, and the adjustment of the photovoltaic panels on both sides can be completed at the same time, the adjustment has a self-locking function, and does not need to be controlled by external motors and other devices, which can reduce the failure caused by long-term maintenance pressure of electric control equipment and improve the stability of the device.

[0019] As a further technical scheme of the present application, the self-cleaning assembly comprises an extension frame, the bottom end of the extension frame is connected with the longitudinal guide rail, the middle of the inner top wall of the extension frame installs a touch switch, the middle of the top end of the extension frame installs a three-way valve, and the front and rear ends of the three-way valve are fixedly connected with spray heads.

[0020] As a further technical solution of the present invention, the top of the three-way valve is connected to an external water pump, and the nozzle has a built-in solenoid valve that is controlled by a tactile switch. When the longitudinal mounting block is at its highest point, it touches the tactile switch and opens the solenoid valve inside the nozzle.

[0021] When the vertical mounting block rises to its highest point, the angle between the bracket assembly and the limit guide rail is at its maximum value. At this point, the photovoltaic panel on the front is close to its maximum vertical position. When the vertical mounting block is at its highest point, it can contact the tactile switch. At this time, the solenoid valve inside the nozzle is activated, and high-pressure water is discharged through the nozzles at both ends of the three-way valve and directly acts on the surface of the photovoltaic panel. The photovoltaic panel, which is in its maximum tilt position, can effectively remove surface dust through the water flow and discharge wastewater, completing the self-cleaning process.

[0022] By utilizing the maximum tilt state of the photovoltaic panel and cooperating with the longitudinal mounting block and self-cleaning component, the water flow is automatically discharged. When the photovoltaic panel is at its maximum tilt state, the water flow speed on the surface is relatively fast, which can quickly remove surface dust. The entire cleaning process can be completed automatically on a regular basis, eliminating the need for manual cleaning by climbing up, thus improving the degree of automation and reducing maintenance difficulty.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. This invention, through the innovative design of the control components, places the turntable operating mechanism inside the photovoltaic cabin. Maintenance personnel do not need to perform any dangerous high-altitude climbing operations; they can simply rotate the turntable indoors to quickly and precisely adjust the tilt angle of the photovoltaic panels through the mechanical linkage of the lead screw, longitudinal guide block, and longitudinal mounting block. This indoor operation method greatly improves the safety and convenience of operation and is unaffected by harsh external weather conditions. The core of the control components adopts a lead screw-nut transmission mechanism, which naturally possesses reverse self-locking characteristics. This means that once the desired angle is adjusted, mechanical friction can ensure that the longitudinal guide block remains stably at any height. Unlike electric devices, there is no need to continuously consume electrical energy to maintain torque, nor is there an additional braking or locking device. This fundamentally avoids fatigue damage or failure of electrical control equipment due to long-term pressure maintenance, significantly improving the long-term stability and reliability of the system.

[0025] 2、The present application adjusts the longitudinal mounting block to the highest point, that is, the photovoltaic panel reaches the maximum inclination angle, the longitudinal mounting block will automatically trigger the light touch switch on the self-cleaning assembly, and then open the electromagnetic valve in the spray head to spray water and clean, ensuring that the cleaning is always in the most efficient state, when the photovoltaic panel is in the maximum inclination state, the water flow is the fastest under the action of gravity, and the scouring force and carrying capacity of dust are the strongest, which can quickly and completely remove the dirt, avoid sewage residue, and this linkage design uses the "end point" of angle adjustment as the "starting point" of cleaning trigger, without additional controller or manual intervention, the cleaning can be automatically completed when adjusting the angle regularly, such as daily, which greatly improves the automation degree, completely solves the difficulty and safety hazard of manual high-altitude cleaning, and guarantees the long-term efficient operation of the photovoltaic panel.

[0026] 3、The present application is connected with the connecting rod through the composite structure of the adjusting block, the clamping groove and the locking bolt, the clamping groove is arranged in the connecting rod, and the adjusting block fixed with the photovoltaic mounting plate can freely slide in the clamping groove; before installing the photovoltaic panel, the staff can adjust the relative positions of two or more photovoltaic mounting plates on the connecting rod according to the actual area and mounting hole position of the used photovoltaic panel by loosening the locking bolt, and after adjusting to the appropriate position, the locking bolt is tightened to fix the position, so that the present application can flexibly adapt to photovoltaic panels of different sizes and different mounting hole distances, and can conveniently and stably install double-sided photovoltaic panels or conventional photovoltaic panels.

[0038] Before the photovoltaic panels are installed, the device needs to be installed at the top end of the photovoltaic shelter, the bottom ends of the operating assemblies 4 need to pass through the roof of the photovoltaic shelter, the operating assemblies 4 can be operated in the shelter, and the top ends of the self-cleaning assemblies 7 need to be connected to the external water pump to ensure the normal supply of water flow.

[0039] As Figure 1 and Figure 4As shown, the operating assembly 4 comprises a longitudinal guide block 401, the left and right ends of the longitudinal guide block 401 are movably connected with the two longitudinal rails 3, the longitudinal guide block 401 moves up and down relative to the longitudinal rails 3, the left and right sides of the top end of the longitudinal guide block 401 are both provided with an extension rod 402, one end of the extension rod 402 away from the longitudinal guide block 401 is connected with the bottom end of the longitudinal mounting block 5, a threaded groove is formed in the middle of the longitudinal guide block 401 and a lead screw 403 is threadedly connected with the threaded groove, the bottom end of the lead screw 403 penetrates through the middle of the bottom end of the base 1 and is movably connected with the base 1, the lead screw 403 rotates relative to the base 1, and a rotating disc 404 is mounted at the bottom end of the lead screw 403.

[0040] When it is necessary to adaptively adjust the deflection angle of the double-sided photovoltaic panel, the rotating disc 404 can be rotated, at which time the lead screw 403 rotates, at which time the longitudinal guide block 401 is driven to move up and down relative to the longitudinal rails 3 under the guidance of the longitudinal guide block 401 and the longitudinal rails 3, at which time the longitudinal guide block 401 drives the longitudinal mounting block 5 to move up and down through the extension rod 402.

[0041] As shown in Figure 1 and Figure 5 and Figure 6 and Figure 7 As shown, the support assembly 6 comprises a first fixed seat 601, one end of the first fixed seat 601 is connected with the end face of the longitudinal mounting block 5, the end of the first fixed seat 601 away from the longitudinal mounting block 5 is movably connected with a connecting rod 603 through a rotating shaft, the end of the connecting rod 603 away from the first fixed seat 601 is movably connected with a second fixed seat 602 through a rotating shaft, the bottom end of the second fixed seat 602 is movably connected with the limiting guide rail 2, the second fixed seat 602 moves back and forth relative to the limiting guide rail 2, the bottom end of the second fixed seat 602 movably mounts a guide block 608, the outer side face of the guide block 608 is in contact with the inner bottom wall of the limiting guide rail 2, the inside of the connecting rod 603 is provided with a clamping groove 604, the upper and lower ends inside the clamping groove 604 are symmetrically movably connected with an adjusting block 605, one side of the adjusting block 605 movably mounts a locking bolt 606, the adjusting block 605 is locked through the locking bolt 606 and the clamping groove 604, the front face of the adjusting block 605 mounts a photovoltaic mounting plate 607, and the photovoltaic mounting plate 607 is fixed with the external photovoltaic panel through bolts.

[0042] When the photovoltaic panel is installed, the back face of the photovoltaic panel can be fixed with the photovoltaic mounting plate 607 through bolts, and the relative position of the photovoltaic mounting plate 607 can be adjusted according to the area of the photovoltaic panel, that is, the locking bolt 606 is loosened, the adjusting block 605 moves relative to the clamping groove 604, and the position of the photovoltaic mounting plate 607 relative to the clamping groove 604 is adjusted correspondingly, so that the two photovoltaic mounting plates 607 can be fixed with the upper and lower ends of the back face of the photovoltaic panel, and the fixing process of the photovoltaic panel is completed.

[0043] When the longitudinal mounting block 5 is displaced up and down, the first fixing seat 601 is displaced up and down at this time, the driving connecting rod 603 swings, and the second fixing seat 602 at the bottom end is displaced forward and backward relative to the limiting guide rail 2, and the guide block 608 rolls relative to the limiting guide rail 2. When the connecting rod 603 rotates, the angle between the connecting rod 603 and the limiting guide rail 2 changes, the angle of the photovoltaic panel located in front of the photovoltaic mounting plate 607 changes, so as to adapt to different light angles and improve the photovoltaic power generation efficiency.

[0044] By utilizing the cooperation between the operating assembly 4 and the support assembly 6, by directly operating the operating assembly 4 in the room, cooperating with the action of the support assembly 6, the angle of the photovoltaic panels on the two sides can be adjusted at the same time, the whole adjustment process can be quickly completed in the room, and the adjustment of the photovoltaic panels on the two sides can be completed at the same time, and the adjustment has a self-locking function, and does not need to be controlled by an external motor and the like, which can reduce the failure caused by long-time maintenance of the electric control equipment, and improve the stability of the device.

[0045] As shown in Figure 1 and Figure 2 and Figure 3 The self-cleaning assembly 7 includes an extension frame 701, the bottom end of the extension frame 701 is connected with the longitudinal guide rail 3, the middle part of the inner top wall of the extension frame 701 is provided with a micro switch 702, the middle part of the top end of the extension frame 701 is provided with a three-way valve 703, the front and rear ends of the three-way valve 703 are fixedly connected with spray heads 704, the top end of the three-way valve 703 is connected with an external water pump, the electromagnetic valve is built in the inside of the spray head 704, and is controlled by the micro switch 702, and the longitudinal mounting block 5 touches the micro switch 702 and opens the electromagnetic valve in the inside of the spray head 704 when it is at the highest point.

[0046] When the longitudinal mounting block 5 rises to the highest point, the angle between the support assembly 6 and the limiting guide rail 2 is at the maximum, and the photovoltaic panel in front is close to the maximum vertical state. When the longitudinal mounting block 5 is at the highest point, it can be in contact with the micro switch 702, at this time, the electromagnetic valve in the inside of the spray head 704 is connected, high-pressure water is led out through the spray heads 704 at both ends of the three-way valve 703, and directly acts on the surface of the photovoltaic panel. The photovoltaic panel in the maximum inclined state cooperates with the sprayed water to effectively remove the surface dust by the water flow, and the sewage is led out, and the self-cleaning process is completed.

[0047] By utilizing the maximum inclined state of the photovoltaic panel, and by cooperating between the longitudinal mounting block 5 and the self-cleaning assembly 7, the automatic leading-out of the water flow is completed, and when the photovoltaic panel is in the maximum inclined state, the water flow speed on the surface is fast, which can quickly remove the surface dust by flowing, the whole cleaning process can be automatically completed regularly without manual cleaning, the degree of automation is improved, and the maintenance difficulty is reduced.

[0048] Working principle and use process:

[0049] First, the entire support system is installed at the top of the photovoltaic shelter, the lead screw 403 and the turntable 404 pass through the top plate of the photovoltaic shelter, and the turntable 404 is located inside the shelter to facilitate safe operation of the staff indoors. At the same time, the three-way valve 703 at the top of the self-cleaning assembly 7 needs to be connected to the external water pump through the pipeline to ensure the normal supply of cleaning water source;

[0050] When the inclination angle of the photovoltaic panel needs to be adjusted to adapt to the change of light, the operator rotates the turntable 404 indoors. The rotation of the turntable 404 directly drives the rotation of the lead screw 403 connected thereto. Since the lead screw 403 is connected to the longitudinal guide block 401 through the thread groove, and the longitudinal guide block 401 is limited by the longitudinal guide rail 3, the rotational movement of the lead screw 403 is converted into the vertical up-down displacement of the longitudinal guide block 401 along the longitudinal guide rail 3. The longitudinal guide block 401 drives the longitudinal mounting block 5 to realize synchronous up-down displacement through the extension rod 402;

[0051] When the longitudinal mounting block 5 moves up and down, the first fixed seat 601 fixed on the end surface thereof moves up and down. The first fixed seat 601 drives the connecting rod 603 to swing through the rotating shaft. The other end of the connecting rod 603 is connected to the second fixed seat 602 through the rotating shaft, and the bottom end of the second fixed seat 602 is clamped in the limiting guide rail 2. Therefore, the swing of the connecting rod 603 forces the second fixed seat 602 to move forward and backward along the limiting guide rail 2. In this process, the guide block 608 rolls relative to the limiting guide rail 2 to ensure smooth movement. As the angle between the connecting rod 603 and the limiting guide rail 2 changes, the angle of the photovoltaic panel fixed on the connecting rod 603 also changes, thereby achieving the purpose of adapting to different light angles and improving power generation efficiency;

[0052] When the operator continuously operates the turntable 404, the longitudinal mounting block 5 automatically touches the micro switch 702 installed on the top wall of the extension frame 701 of the self-cleaning assembly 7,

[0053] When the micro switch 702 is touched, it is connected, thereby controlling the electromagnetic valve installed in the spray head 704 to open. At this time, the high-pressure water flow supplied by the external water pump passes through the three-way valve 703 and is quickly sprayed from the spray heads 704 at the front and rear ends, directly acting on the surface of the photovoltaic panel. The cleaning process occurs when the photovoltaic panel is in the maximum inclination state (close to vertical). The high-pressure water flow combined with the action of gravity can quickly flush the surface of the photovoltaic panel at a high flow rate, efficiently removing surface dust and dirt, and quickly guiding out the sewage, thereby automatically completing the cleaning process;

[0054] In the installation process, the adjusting block 605 can be slid up and down in the clamping groove 604 inside the connecting rod 603 by loosening the locking bolt 606, so as to conveniently adjust the relative positions of the photovoltaic mounting plates 607, to ensure that they can be fixed to the upper and lower ends of the back of the photovoltaic panel with different areas and different mounting hole positions, and the installation of the photovoltaic panel is completed.
