Description

Technical Field

[0001] This utility model belongs to the technical field of water surface photovoltaic construction devices, specifically relating to fixed devices for water surface photovoltaic construction. Background Technology

[0002] Floating photovoltaic (PV) systems refer to photovoltaic power generation systems built on water surfaces such as reservoirs and lakes. Typically, a support pillar is installed in the lake, and photovoltaic panels are mounted on the pillar to generate electricity through sunlight.

[0003] A fixing device for the construction of a floating photovoltaic power station, disclosed in patent number "CN114204884A", includes a support plate and clamping plates. The clamping plates are symmetrically and slidably mounted on both sides of the upper part of the support plate. A first connecting rod is also slidably mounted on both sides of the support plate, and both sides of the first connecting rod are slidably connected to the clamping plates. A rack is also mounted on the inner side of the first connecting rod. During high or low tide, the fifth and sixth connecting rods move up and down, causing the winding wheel to rotate and releasing or retracting the pull rope. This achieves automatic release and retraction of the pull rope and prevents the solar panels from being submerged. However, in existing floating photovoltaic construction, operators need to carry a large number of tools and connect the photovoltaic panels to the support pillars using screws. This fixing process is cumbersome and difficult to perform in a lake environment. Furthermore, once the photovoltaic panels are installed, their position is fixed. During high tide, the lake water can submerge the photovoltaic panels, affecting their normal power generation and potentially causing damage. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] This embodiment provides a fixed device for the construction of a water-surface photovoltaic system, such as... Figure 1-6 As shown, the system includes a support column 1, a photovoltaic bracket 2, and a photovoltaic panel 3. The photovoltaic panel 3 is fixedly installed on the top of the photovoltaic bracket 2, which is located on top of the support column 1. A mounting plate 4 is provided on the top of the support column 1. Two housings 5 ​​are fixedly connected to the top of the mounting plate 4. A fixing mechanism is provided inside the housings 5. Positioning blocks 6 are fixedly connected to both sides of the photovoltaic bracket 2. The fixing mechanism includes a rotating block 7 located inside the housing 5. A rotating rod 8 is fixedly connected to the top of the rotating block 7. Two pressing blocks 9 are provided at the bottom of the rotating block 7. A linkage block 28 is fixedly connected to the side of the two pressing blocks 9 that is far from each other. Two positioning rods 10 are fixedly connected to the side of the linkage block 28 that is far from the pressing blocks 9. One end of the positioning rod 10 extends to the outside of the housing 5. A positioning hole 11 is provided on one side of the positioning block 6 to cooperate with the positioning rod 10. Two pressing rods 12 are fixedly connected to the bottom of the rotating block 7. A pressing groove 13 is provided on the top of the pressing block 9 to cooperate with the pressing rod 12. An adjustment mechanism is fixedly installed inside the support column 1 and can adjust the height of the photovoltaic panel 3 according to the water level.

[0028] In this embodiment, considering that existing floating photovoltaic systems require operators to carry numerous tools and use screws to connect the photovoltaic panel 3 to the support column 1 during installation, which is cumbersome and difficult to perform in a lake environment, a fixing mechanism is designed. During installation, by simultaneously rotating two turning blocks 24, the turning blocks 24 drive the rotating rod 8 and rotating block 7 to rotate around the bearing 25. The pressing rod 12 rotates synchronously with the rotating block 7. As the pressing rod 12 rotates, its surface contacts the inner wall of the pressing groove 13, thereby pressing and driving the two... The pressing block 9 moves to the side that is closer to each other. The pressing block 9 will drive the linkage block 28 and the positioning rod 10 to move, so that the positioning rod 10 retracts into the housing 5, and moves the photovoltaic panel 3 to the top of the mounting plate 4, aligning it with the position of the housing 5. This makes the positioning blocks 6 on both sides of the photovoltaic bracket 2 located on both sides of the housing 5. Then, the screwing block 24 is released, and the tension generated by the tension spring 23 will drive the linkage block 28 and the positioning rod 10 to reset, so that the positioning rod 10 enters the corresponding positioning hole 11, completing the fixation of the positioning block 6, and thus completing the fixation of the photovoltaic bracket 2 and the photovoltaic panel 3, which facilitates the installation and fixation.

[0029] Example 2

[0030] Based on Embodiment 1, a tension spring 23 is fixedly connected to one side of the linkage block 28, and one end of the tension spring 23 is fixedly connected to the inner wall of the housing 5.

[0031] In this embodiment, by setting a tension spring 23, when the screwing block 24 is loosened, the tension force generated by the tension spring 23 drives the linkage block 28 and the positioning rod 10 to enter the reset position, so that the positioning rod 10 enters the interior of the corresponding positioning hole 11, thus achieving the reset function.

[0032] Example 3

[0033] Based on embodiment 2, the top of the rotating rod 8 extends through to the top of the housing 5 and is fixedly connected to a screwing block 24. The bottom of the screwing block 24 is rotatably connected to the top of the housing 5 through a bearing 25.

[0034] In this embodiment, by setting the twisting block 24 and the bearing 25, a gripping force point can be provided for the user when the user needs to rotate the rotating rod 8, thereby facilitating the driving function. At the same time, the bearing 25 can improve the smoothness of the rotation of the rotating rod 8 and other structures.

[0035] Example 4

[0036] Based on embodiment 3, two limiting blocks 26 are fixedly connected to the inner wall of the housing 5, and a limiting groove 27 that cooperates with the limiting blocks 26 is opened on the top of the extrusion block 9.

[0037] In this embodiment, by setting the limiting block 26 and the limiting groove 27, the movement trajectory of the extrusion block 9 and other structures can be restricted. When the extrusion rod 12 rotates and contacts the inner wall of the extrusion groove 13, it is affected by the extrusion, causing the extrusion block 9 to move towards the side that is closer to each other, thus restricting the movement trajectory.

[0038] Example 5

[0039] Based on Example 4, this example considers that after the photovoltaic panel 3 is installed, its position is fixed. In case of high tide, the lake water will submerge the photovoltaic panel 3, affecting the normal power generation of the photovoltaic panel 3, and in severe cases, it may cause damage to the photovoltaic panel 3. The adjustment mechanism in this application includes a motor 14 fixedly installed inside the support column 1. The output end of the motor 14 is fixedly connected to a threaded rod 15. The surface of the threaded rod 15 is connected to a support rod 16. The top of the support rod 16 is fixedly connected to the bottom of the mounting plate 4. The bottom of the support rod 16 is provided with a threaded hole 17 for use with the threaded rod 15. A controller 18 that is signal-connected to the motor 14 is fixedly installed on one side of the photovoltaic panel 3. A liquid level sensor 19 is fixedly installed on one side of the support column 1. The controller 18 and the liquid level sensor 19 are signal-connected.

[0040] In this embodiment, an adjustment mechanism is provided so that when the lake water rises, the liquid level sensor 19 receives a signal and transmits the signal to the controller 18. The controller 18's built-in PLC module starts the motor 14. The motor 14 drives the threaded rod 15 to rotate, and the external thread on the surface of the threaded rod 15 will squeeze the internal thread of the threaded hole 17, causing the support rod 16 to move upward. At the same time, it drives the mounting plate 4 to move upward, thereby causing the photovoltaic bracket 2 and the photovoltaic panel 3 to move upward, thus preventing the tide from submerging the photovoltaic panel 3 and affecting the normal power generation of the photovoltaic panel 3.

[0041] Sliding blocks 20 are fixedly connected to both sides of the support rod 16, and a sliding groove 21 that cooperates with the sliding block 20 is opened on the inner wall of the support column 1.

[0042] In this embodiment, by setting the sliding block 20 and the sliding groove 21, when the threaded rod 15 rotates to transmit power to the support rod 16, the support rod 16 is restricted to move only along the trajectory of the sliding block 20 and the sliding groove 21, thereby improving its stability during movement.

[0043] Example 6

[0044] Based on the above embodiment, a sealing block 22 is fixedly connected to the inner wall of the support column 1, and the inner wall of the sealing block 22 is in contact with the output end of the motor 14.

[0045] In this embodiment, by setting the sealing block 22, the motor 14 can be kept in a sealed state, preventing lake water from affecting the normal operation of the motor 14. At the same time, the motor 14 can be a waterproof motor 14, and since the motor 14 is underwater, there is no need to consider the heat dissipation problem.

[0046] The fixing device for water surface photovoltaic construction provided by this utility model works as follows: During installation, by simultaneously rotating two screwing blocks 24, the screwing blocks 24 will drive the rotating rod 8 and the rotating block 7 to rotate around the bearing 25. The pressing rod 12 will rotate synchronously with the rotating block 7. While the pressing rod 12 rotates, its surface will contact the inner wall of the pressing groove 13. Through pressing, the two pressing blocks 9 will move towards each other. The pressing blocks 9 will drive the linkage block 28 and the positioning rod 10 to move, so that the positioning rod 10 retracts into the housing 5, and the photovoltaic panel 3 is moved to the top of the mounting plate 4 and aligned with the position of the housing 5, so that the positioning blocks 6 on both sides of the photovoltaic bracket 2 are respectively located on both sides of the housing 5. Then, the screwing blocks 24 are released, and the tension generated by the tension spring 23 will drive the linkage block 28 and the positioning rod 10 to reset, so that the positioning rod 10 enters the corresponding positioning hole 11, and the positioning block 6 is fixed, thereby fixing the photovoltaic bracket 2 and the photovoltaic panel 3, which facilitates installation and fixing.

[0047] When the lake water rises, the liquid level sensor 19 receives a signal and transmits it to the controller 18. The controller 18's built-in PLC module starts the motor 14. The motor 14 drives the threaded rod 15 to rotate, and the external thread on the surface of the threaded rod 15 presses against the internal thread of the threaded hole 17, causing the support rod 16 to move upward. At the same time, it drives the mounting plate 4 to move upward, thereby causing the photovoltaic bracket 2 and the photovoltaic panel 3 to move upward, thus preventing the tide from submerging the photovoltaic panel 3 and affecting the normal power generation of the photovoltaic panel 3.

[0048] It should be noted that the motor 14, controller 18 and liquid level sensor 19 are existing devices or equipment in the prior art, or are devices or equipment that can be implemented in the prior art. The specific composition and principle of the power supply of the motor 14, controller 18 and liquid level sensor 19 are clear to those skilled in the art, so they will not be described in detail here.

[0049] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0050] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
