DETAILED DESCRIPTION
[0023] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.
[0024] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.
[0025] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.
[0026] See also Figures 1 to 6 In an embodiment of the utility model, a high temperature resistant photovoltaic assembly includes a box body 1, a box top 2, a heat dissipation port 3, a heat dissipation assembly, a centrifugal structure, and a threaded pusher.
[0027] The details are as follows, including:
[0028] See also Figure 2 , Figure 3 , Figure 4 , a box body 1 and a box top 2 fixedly mounted on the box body 1, the box top 2 is provided with a plurality of heat dissipation openings 3, and also includes a heat dissipation component mounted on the box top 2 to dissipate heat inside the box body 1;
[0029] A centrifugal structure, mounted on the box top 2, connected to the heat dissipation assembly;
[0030] The threaded pusher is symmetrically arranged, installed on the box top 2, and connected to the centrifugal structure. When the heat dissipation component performs heat dissipation work, the threaded pusher is driven by the centrifugal structure to release the partial blocking state of the heat dissipation port 3.
[0031] Among them, it is also necessary to explain that the inner side of the box 1 is installed with an inverter and other devices to convert the solar energy transmitted by the photovoltaic panel into electrical energy. During the conversion process, it must be ensured that the temperature inside the box 1 is not too high to affect the energy conversion. Therefore, the box 1 is integrated with a temperature sensing device for detecting the temperature inside the box 1 to achieve normal operation of the thermal energy conversion. The specific temperature sensing device can adopt an existing structure, which will not be described in detail in this embodiment.
[0032] Of course, the heat dissipation component is also connected to a driving component installed in the top 2 of the box. The driving component can be a motor. The heat dissipation component is driven by the motor. The motor is connected to a control unit. The control unit establishes communication with the above-mentioned temperature sensing device. Once the temperature in the box body 1 is too high, a signal is sent to the control unit, and the control unit controls the motor to rotate a certain angle and then stop automatically. The control unit includes but is not limited to a control button and an integrated circuit board installed on the top 2 of the box. The method of controlling the motor belongs to conventional design, and this embodiment does not make specific limitations on this.
[0033] In detail, in this embodiment, the high-temperature resistant photovoltaic components described in the utility model are adopted, and the inverter and other devices in the box 1 will generate heat when working. The more heat energy is converted, the faster the temperature inside the box 1 rises. In order to prevent the temperature inside the box 1 from affecting normal work, when the temperature is too high, the heat dissipation component is controlled to work to dissipate the heat of the internal device of the box 1. When the heat dissipation component is working, it drives the centrifugal mechanism to generate mechanical movement, and the transmission thread pusher works to release the blocking device of the heat dissipation port 3, so that the high temperature in the box 1 can be quickly reduced, and the temperature in the box 1 is always in a stable state. Among them, when the heat dissipation component is not in working state, the heat dissipation port 3 maintains a part of the conductive state to ensure the air circulation inside the box 1, so that when the temperature dissipated by the heat exchange conversion is relatively small, natural wind heat dissipation is achieved.
[0034] The heat dissipation component includes an impeller shaft 4 , which is rotatably mounted on the box top 2 , and a plurality of groups of blades 5 are fixedly arranged on the impeller shaft 4 , and the blades 5 are arranged along the radial direction of the impeller shaft 4 .
[0035] The centrifugal structure includes a connecting plate 6, which is fixedly mounted on the impeller shaft 4. A slide groove is formed on the connecting plate 6, and a slider 8 is slidably arranged in the slide groove. The slider 8 is connected to the threaded pusher through a transmission member.
[0036] It also includes a spring 7, which is arranged in the slide groove. One end of the spring 7 is fixedly connected to the slider 8, and the other end is fixedly connected to the inner wall of the slide groove.
[0037] The transmission member includes a rotating shaft 10, which is arranged along the axial direction of the impeller shaft 4. A sleeve 11 is slidably arranged on the rotating shaft 10, a connecting sleeve 14 is rotatably installed on the sleeve 11, a connecting rod 9 is rotatably connected to the connecting sleeve 14, and one end of the connecting rod 9 away from the connecting sleeve 14 is rotatably connected to the slider 8. A movable plate 15 is fixedly connected to the sleeve 11, and sleeves 16 are respectively fixedly arranged at both ends of the movable plate 15, and a ball 18 is movably arranged on the sleeve 16.
[0038] To elaborate, when the impeller shaft 4 rotates, the speed of the impeller shaft 4 is a gradually increasing process, and the speed of the impeller shaft 4 gradually increases to the rated speed. When the impeller shaft 4 rotates, it drives the connecting plate 6 to rotate synchronously. When the speed of the connecting plate 6 gradually increases, it drives the slider 8 to make a linear motion in the slide groove of the connecting plate 6 and moves toward the side away from the impeller shaft 4. The slider 8 squeezes the spring 7 when moving, and the spring 7 is squeezed to reserve elastic potential energy. When the slider 8 moves, it drives the threaded pusher to work through the transmission member, so as to realize that the blocking plate 20 releases the blocking state of the heat dissipation port 3.
[0039] When the slider 8 moves, the connecting sleeve 14 is driven to rotate and move through the connecting rod 9. When the connecting sleeve 14 moves, the sleeve 11 is driven to move synchronously. When the sleeve 11 moves, the movable plate 15 is driven to follow the movement, so that the ball 18 on the sleeve 16 generates an extrusion force on the threaded pusher to achieve the driving requirement of the threaded pusher.
[0040] Preferably, at least one set of limiting sliding blocks 12 is formed on the rotating shaft 10 , and a limiting sliding groove 13 slidably matched with the limiting sliding blocks 12 is formed on the inner wall of the sleeve 11 .
[0041] It should be noted that: when the sleeve 11 moves, the limiting groove 13 on the sleeve 11 moves synchronously, and cooperates with the limiting effect of the limiting slider 12 to realize the movement of the sleeve 11 relative to the rotating shaft 10. The limiting slider 12 is slidably installed in the limiting groove 13, thereby realizing the sliding connection between the sleeve 11 and the rotating shaft 10, and preventing the sleeve 11 from rotating with the rotation of the connecting sleeve 14.
[0042] The threaded pusher includes a cylindrical member 17, which is rotatably mounted on the box top 2. A threaded groove that movably cooperates with the ball 18 is formed on the cylindrical member 17. An external thread is formed on the end of the cylindrical member 17 away from the threaded groove. A threaded sleeve 19 is threadedly connected to the external thread. A sealing plate 20 is fixedly mounted on the end of the threaded sleeve 19 away from the cylindrical member 17. The sealing plate 20 is slidably arranged in the box top 2, and the sealing plate 20 seals part of the heat dissipation port 3.
[0043] When the sleeve 16 moves, it cooperates with the threaded groove on the columnar member 17, and the ball 18 generates an extrusion force on the columnar member 17. To ensure that the ball 18 always moves in the threaded groove, the columnar member 17 is rotated. When the columnar member 17 rotates, it drives the threaded sleeve 19 to make a linear motion along the axial direction of the columnar member 17. When the threaded sleeve 19 moves, it drives the blocking plate 20 to move synchronously to realize the unblocking of the heat dissipation port 3. Among them, the blocking plate 20 cannot completely block all the heat dissipation ports 3. Some heat dissipation ports 3 must always be kept in a ventilated state to ensure the air circulation inside the box body 1, so that the temperature dissipated by the heat exchange conversion is relatively low, and natural wind heat dissipation is achieved.
