Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic panel support devices, and in particular relates to a photovoltaic panel support device for photovoltaic energy storage. Background Technology

[0002] A photovoltaic (PV) panel is a device that converts solar energy into electrical energy. It is mainly composed of photovoltaic cells, which are usually made of semiconductor materials. The working principle of a PV panel is based on the photovoltaic effect, that is, when sunlight shines on a PV cell, photons are absorbed and electrons are excited. These electrons form an electric field inside the semiconductor material, thereby generating current. This current can be directly used to drive electrical appliances or stored in batteries. When collecting solar energy, PV panels need to be placed on a support device. Existing support devices are usually fixed structures. When PV panels store energy through sunlight, different positions will affect the energy stored due to different sunlight. Although there are devices that can adjust the angle, their structure is relatively complex and costly, and it is not convenient to maintain and replace the adjustment device. Utility Model Content

[0024] Example 1

[0025] This embodiment describes a photovoltaic panel support device for photovoltaic energy storage, such as... Figure 1 and Figure 5 As shown, it includes a support frame 1, which is used to install photovoltaic panels. The photovoltaic panels are fixed to the support frame 1 by means of pressure blocks or bolts.

[0026] The bottom of the support frame 1 is vertically provided with several sets of support components distributed in front and behind. The support components include two fixed rods 4. The top of the fixed rods 4 is detachably connected to the bottom of the support frame 1, which facilitates the support of the support frame 1 and also facilitates the maintenance and replacement of the photovoltaic panel and the support frame 1, thereby improving efficiency and reducing costs.

[0027] Two fixing pipes 5 are vertically installed at the bottom of the support frame 1 between the fixing rods 4, and the fixing rods 4 and fixing pipes 5 are symmetrically distributed along the bottom of the support frame 1, which facilitates further increase of the support effect, reduces the stress on the support frame 1, thereby improving stability and effectively extending the service life of the support frame 1, thus preventing the photovoltaic panels on the support frame 1 from falling off.

[0028] The fixed tube 5 is detachably equipped with a lifting component. The lifting component is used to cooperate with the fixed rod 4 to drive the support frame 1 to swing up and down. In its natural state, the support frame 1 is horizontal, which makes it easy to adjust the angle of the support frame 1 according to different time periods and sunlight conditions, so that the photovoltaic panels installed on the support frame 1 can convert sunlight to the maximum extent and make its energy conversion rate higher.

[0029] Example 2

[0030] This embodiment further illustrates the technology, such as Figure 1 and Figure 5 As shown, there are two sets of fixing rods 4, arranged horizontally. Each set consists of two rods, arranged front to back. A support rod 3 is horizontally fixed between the two fixing rods 4. Connecting seats 2 are fixed at both ends of the bottom of the connecting seat 2. The bottom of the connecting seat 2 has a groove for the support rod 3 to pass through. When the connecting seat 2 is fastened to the support rod 3 through the groove, it swings up and down with the support rod 3. The swing amplitude of the connecting seat 2 and the support rod 3 is less than 90 degrees, facilitating the fastening of the support frame 1 to the support rod 3 via the connecting seat 2. Then, the lifting assembly... The lifting component drives the support frame 1 to swing on the support rod 3. When the lifting component is at its maximum amplitude, the swing amplitude of the connecting seat 2 and the support frame 1 on the support rod 3 should be less than 90 degrees. This avoids the connecting seat 2 from falling off the support rod 3 and damaging the support frame 1 and the photovoltaic panel when the lifting component drives the support frame 1 to swing and adjust the angle. Furthermore, when replacing or maintaining the support frame 1 or the photovoltaic panel, the support frame 1 can be completely removed from the support rod 3, thereby reducing the difficulty of maintenance personnel's work, making maintenance more efficient, and thus improving the energy conversion efficiency to a certain extent.

[0031] Example 3

[0032] This embodiment further illustrates the technology, such as Figure 1 , Figure 3 and Figure 5As shown, the lifting assembly includes an electric push rod 6, a closed bottom of a fixed tube 5, and two fixed blocks 10 horizontally fixed at the bottom of the fixed tube 5 in a front-to-back arrangement. The bottom of the electric push rod 6 is hinged between the two fixed blocks 10 via a guide rod 11 and swings left and right. The left and right side walls of the fixed tube 5 are provided with first through slots for the electric push rod 6 to swing left and right. A hinge assembly is detachably provided between the push rod end of the electric push rod 6 and the support frame 1. The electric push rod 6 is hinged to the bottom of the support frame 1 via the hinge assembly and swings left and right. This makes it easy to push the support frame 1 upward with the electric push rod 6 to adjust the tilt angle of the photovoltaic panel on the support frame 1 and improve the solar energy conversion efficiency. In use, the support frame 1 is pushed upward at an angle by the electric push rod 6. During the process, the support frame 1 rotates on the support rod 3 via the connecting seat 2 to complete the unilateral upward swing.

[0033] The electric actuator 6 is existing technology. Also known as a linear actuator, it can be considered a structural extension of a rotary motor. The electric actuator is a novel linear execution mechanism mainly composed of a motor actuator and a control device. It is powered by electricity converted from photovoltaic panels. The support frame 1, fixed rod 4, or fixed tube 5 are equipped with a controller for remotely controlling the opening and closing of the electric actuator 6 and a sensor for detecting sunlight. The controller is electrically connected to both the sensor and the electric actuator 6.

[0034] In practice, for ease of monitoring and management, monitoring is usually installed in the area where the photovoltaic panels are installed. In addition to transmitting signals to the controller through sensors to control the electric push rod 6 to open and close and adjust the tilt angle of the photovoltaic panels, the environment can also be monitored and the panel can be manually adjusted.

[0035] Example 4

[0036] This embodiment further illustrates the technology, such as Figure 2 and Figure 5 As shown, the connecting assembly includes a fixed plate 8, the top of which is fixed to the bottom of the support frame 1. A connecting plate 9, which swings left and right, is hinged to the bottom of the fixed plate 8. A connecting groove is provided at the bottom of the connecting plate 9. A connector 7, which is interference-fitted with the connecting groove, is fixed to the top of the push rod of the electric push rod 6. A limiting component is provided on the fixed plate 8 to disengage the connecting plate 9 from the connector 7. This facilitates the connection of the electric push rod 6 to the connecting plate 9, and then the support frame 1 is lifted upward to adjust its tilt angle. When maintaining the photovoltaic panels on the electric push rod 6 or the support frame 1, the position of the connecting plate 9 is fixed by the limiting component, and then the electric push rod 6 continues to retract downward to disengage the connector 7 from the connecting plate 9. Then the support frame 1 or the electric push rod 6 can be disassembled separately, thereby greatly improving its maintenance efficiency.

[0037] Example 5

[0038] This embodiment further illustrates the technology. The diameter of the support rod 3 is smaller than the depth of the groove, and an elastic stop is provided at the groove opening. The distance between the stop blocks is smaller than the diameter of the support rod 3, which helps to prevent the support rod 3 from falling out of the groove when the electric push rod 6 drives the bearing frame 1 to swing, thereby increasing its stability.

[0039] The stop block is provided with a protective layer to increase friction, thereby further enhancing the connection effect and preventing direct detachment.

[0040] Example 6

[0041] This embodiment further illustrates the technology, such as Figure 4 As shown, the limiting assembly includes two limiting blocks 12, which are respectively fixed to the front and rear side walls of the fixing plate 8. The diameter of the fixing tube 5 is smaller than the distance between the two limiting blocks 12. The front and rear side walls at the top of the fixing tube 5 are provided with second through slots for placing the limiting blocks 12. When the support frame 1 is horizontal, the fixing plate 8 is located in the second through slot, which fixes the position of the connecting plate 9. Then, the connecting head 7 is disengaged from the limiting slot by retracting the electric push rod 6, so that the electric push rod 6 and the support frame 1 exist independently, making maintenance more convenient.

[0042] Example 7

[0043] This embodiment further explains the technology. A damping plate is provided between the fixing block 10 and the guide rod 11 so that the position of the electric push rod 6 can be fixed when it stops swinging, and avoids the electric push rod 6 from falling from the first through groove to the outside of the fixing tube 5 and causing damage after the electric push rod 6 is retracted into the fixing tube 5 and the connector 7 is separated from the connecting plate 9.

[0044] The guide rod 11 is a screw rod. The fixing block 10 is provided with through holes for the two ends of the guide rod 11 to pass through. The guide rod 11 located outside the through hole is fitted with a nut that is threaded to it. The damping plate is set on the guide rod 11 between the fixing block 10 and the electric push rod 6 to increase the friction force so that the electric push rod 6 can stop at different angles in the natural state.

[0045] The guide rod 11 can also be equipped with double nuts, which can improve the connection effect and prevent the nuts from falling off during repeated swinging.

[0046] The working principle is as follows: First, one of the electric push rods 6 is activated, which lifts the connecting plate 9 and the fixing plate 8 upward, thereby causing one side of the support frame 1 to swing upward. During the extension of the electric push rod 6, its bottom swings on the guide rod 11 and the hinge swing of the fixing plate 8 and the connecting plate 9 allows the electric push rod 6 to continuously push the support frame 1. Then, following the sunlight, the swing angle of the support frame 1 is adjusted until it is horizontal. When the support frame 1 is horizontal, the limiting block 12 is placed in the second through groove. The electric push rod 6 continues to retract, causing the connector 7 to disengage from the connecting plate 9. Then, the other electric push rod 6 is activated to rise, so that its connector 7 is inserted into the limiting groove on the other side. Then, following the angle of the sunlight, the support frame 1 is swung to the other side. After the sun sets in the west, the electric push rod 6 is retracted until the support frame 1 is horizontal.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
