Description
Technical Field
[0001] The invention relates to the technical field of fuses, in particular to a photovoltaic protection fuse with a rapid heat dissipation function. Background Art
[0002] Photovoltaic protection fuses play a key role in photovoltaic power generation systems. However, photovoltaic systems may face safety hazards such as abnormal current, overload, and short circuit during operation. If these problems are not handled in a timely manner, they may cause fires and electrical accidents, threatening system stability and user safety. For this reason, photovoltaic protection fuses came into being. As an overcurrent protection device, it can quickly cut off abnormal or fault currents and effectively prevent fires and electrical accidents. At the same time, it also has multiple protection functions, is environmentally friendly and recyclable.
[0003] At present, traditional photovoltaic protection fuses may rely solely on natural heat dissipation due to their traditional heat dissipation design, resulting in slow internal air circulation and low heat dissipation efficiency. At the same time, traditional photovoltaic protection fuses may be in a closed or semi-enclosed space. Due to poor internal ventilation, the heat dissipation effect is seriously affected, which easily affects the use of the device in a high temperature environment. In view of this, we propose a photovoltaic protection fuse with rapid heat dissipation function. Summary of the invention
[0004] The main purpose of the present invention is to provide a photovoltaic protection fuse with a rapid heat dissipation function, which can solve the problems raised in the above background technology.

A first compression spring is welded to the outer wall of the power storage seat. One end of the first compression spring away from the power storage seat is welded to the outer wall of the power storage block. A sliding groove is formed in the power storage seat. The power storage block is slidably connected to the inner wall of the sliding groove. The sliding groove guides the moving direction of the power storage block. The movement of the sliding rod drives the power storage seat to move. The first compression spring prevents the power storage block from leaving the power storage seat.
[0007] Preferably, a fixed rod is fixedly connected to the inner wall of the fuse body. A rotating rod is rotatably connected to the outer wall of the fixed rod. A fixed shaft is fixedly connected to the outer wall of the fixed rod. The inner wall of the rotating rod is rotatably connected to the outer wall of the fixed shaft.

[0008] Preferably, a second fixed stop is fixedly connected to the outer wall of the rotating rod. A third fixed stop is fixedly connected to the outer wall of the power storage seat. The third fixed stop is provided with an inclined surface. The movement of the power storage block drives the first fixed stop to move synchronously. When the first fixed stop contacts the second fixed stop, the second fixed stop blocks the first fixed stop, causing the first fixed stop to stop moving, and the power storage block also stops moving synchronously, compressing the first compression spring for power storage work.
[0009] Preferably, the flow disturbance structure includes a first curved rod. A fixed frame is fixedly connected to the outer wall of the first curved rod. One end of the first curved rod is fixedly connected to the top of the power storage block. The other end of the first curved rod is fixedly connected to the top of the fixed frame. The movement of the power storage block drives the first curved rod to move, thereby causing the fixed frame to move.
[0010] Preferably, a push rod is fixedly connected to the outer wall of the fixed frame. A second support plate is fixedly connected to the inner wall of the fuse body. One end of the push rod away from the fixed frame is designed as a curved surface. Multiple groups of push rods are provided.
[0011] Preferably, a flow disturbance plate is rotatably connected to the outer wall of the second support plate. A fourth fixed stop is fixedly connected to the outer wall of the second support plate. The second support plate rotatably supports the flow disturbance plate. The fourth fixed stop limits the rotation range of the flow disturbance plate.
[0012] Preferably, a force-receiving rod is fixedly connected to one end of the flow disturbance plate. A second compression spring is fixedly connected to the other end of the flow disturbance plate. One end of the second compression spring away from the flow disturbance plate is welded to the inner wall of the fuse body. The force-receiving rod can be pushed by the moving push rod, thereby driving the flow disturbance plate to rotate on the second support plate, and at the same time compressing the second compression spring.

The movement of the second curved rod drives the connecting rod to move. The wind deflector can block the ventilation opening. By flexibly changing the opening and closing state of the ventilation opening, the flexibility of the device is improved.
[0014] Preferably, a guiding seat is fixedly connected to the inner wall of the ventilation opening. A pushing rod is slidably connected to the inner wall of the guiding seat. The end of the connecting rod away from the second curved rod is hinged to the outer wall of the pushing rod. The guiding seat guides the moving direction of the pushing rod. The movement of the connecting rod drives the pushing rod to slide on the inner wall of the guiding seat. The pushing rod pushes the wind deflector, thereby causing the wind deflector to rotate and facilitating the opening of the ventilation opening.
[0015] The present invention provides a photovoltaic protection fuse with a fast heat dissipation function, having the following beneficial effects: (1) Through the ingenious combination of the energy storage structure and the flow disturbance structure, the pushing rod pushes the stress rod at a more coherent and enhanced speed, thereby driving the flow disturbance plate to perform efficient flow disturbance. This not only accelerates the air circulation speed inside the fuse body but also significantly improves the heat dissipation effect, ensuring that the fuse can maintain a stable working state in a high-temperature environment.
[0016] (2) When the temperature of the fuse body rises, the airbag can quickly expand and squeeze the movable disk, triggering a series of chain reactions. This delicate design enables an extremely rapid heat dissipation response, which can promptly and effectively reduce the temperature of the fuse body, thereby ensuring its normal operation and extending its service life.
[0017] (3) The movement of the energy storage base simultaneously drives the opening mechanism of the ventilation opening, enabling the ventilation opening and the flow disturbance plate to work in coordination to jointly promote rapid heat dissipation. This intelligent ventilation design further enhances the heat dissipation effect, provides more comprehensive and efficient temperature protection for the fuse, and ensures its long-term stable operation.

[0021] The realization, functional features and advantages of the purpose of the present invention will be further described with reference to the embodiments and the accompanying drawings. Specific embodiments
[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0023] Please refer to Figure 1-6, the present invention provides a photovoltaic protection fuse with a fast heat dissipation function, including a fuse body 1. An installation seat 2 is fixedly connected to the outer wall of the fuse body 1. Installation holes are provided on the installation seat 2, which facilitates the installation of the fuse body 1 through the installation holes. A flow disturbance structure 3 is arranged on the inner wall of the fuse body 1, and a power storage structure 4 is arranged on the inner wall of the fuse body 1. The power storage structure 4 includes a first support plate 41. The first support plate 41 is fixedly connected to the inner wall of the fuse body 1. A cylinder 42 is fixedly connected to the top of the first support plate 41. An airbag 43 is fixedly connected to the inner wall of the cylinder 42. A movable disk 44 is slidably connected to the inner wall of the cylinder 42. When the temperature of the fuse body 1 rises, the airbag 43 will expand. By the expanded airbag 43 squeezing the movable disk 44, the movable disk 44 slides on the inner wall of the cylinder 42. A sliding rod 45 is fixedly connected to the top of the movable disk 44. The outer wall of the sliding rod 45 is slidably connected to the inner wall of the cylinder 42. By the sliding rod 45 sliding on the inner wall of the cylinder 42, the direction of movement of the movable disk 44 is guided, improving the stability of the movement of the movable disk 44. A power storage seat 46 is fixedly connected to the top of the sliding rod 45.
[0024] In an embodiment of the present invention, in order to conveniently improve the moving speed of the push rod 33, a power storage block 47 is slidably connected to the inner wall of the power storage seat 46. A first fixed stop 5 is fixedly connected to the outer wall of the power storage block 47. A first compression spring 48 is welded to the outer wall of the power storage seat 46. The end of the first compression spring 48 away from the power storage seat 46 is welded to the outer wall of the power storage block 47. A sliding groove is provided on the power storage seat 46. The power storage block 47 is slidably connected to the inner wall of the sliding groove. Driven by the movement of the sliding rod 45, the power storage seat 46 moves, and the power storage block 47 moves synchronously through the first compression spring 48.
[0025] Furthermore, a fixed rod 6 is fixedly connected to the inner wall of the fuse body 1. A rotating rod 7 is rotatably connected to the outer wall of the fixed rod 6. A fixed shaft is fixedly connected to the outer wall of the fixed rod 6, and the inner wall of the rotating rod 7 is rotatably connected to the outer wall of the fixed shaft. The rotating rod 7 is supported by the fixed rod 6. Due to the self-gravity of the rotating rod 7, the rotating rod 7 will maintain a vertically downward state. A second fixed stop 8 is fixedly connected to the outer wall of the rotating rod 7, and a third fixed stop 9 is fixedly connected to the outer wall of the energy storage seat 46. The movement of the energy storage block 47 will drive the first fixed stop 5 to move synchronously. When the first fixed stop 5 comes into contact with the second fixed stop 8, the second fixed stop 8 blocks the first fixed stop 5, causing the first fixed stop 5 to stop moving, and the energy storage block 47 also stops moving synchronously, compressing the first compression spring 48 to store energy. At this time, the energy storage seat 46 will still move. When the third fixed stop 9 on the energy storage seat 46 moves to the position of the rotating rod 7, the third fixed stop 9 will squeeze the rotating rod 7, causing the rotating rod 7 to rotate, and then driving the second fixed stop 8 away from the first fixed stop 5. The compressed first compression spring 48 will automatically reset, driving the energy storage block 47 to slide in the energy storage groove. The reset of the first compression spring 48 can increase the sliding speed of the energy storage block 47 in the energy storage groove.
[0026] Furthermore, the flow disturbance structure 3 includes a first curved rod 31. A fixed frame 32 is fixedly connected to the outer wall of the first curved rod 31. One end of the first curved rod 31 is fixedly connected to the top of the energy storage block 47, and the other end of the first curved rod 31 is fixedly connected to the top of the fixed frame 32. The movement of the energy storage block 47 drives the first curved rod 31 to move, and then the fixed frame 32 moves. A push rod 33 is fixedly connected to the outer wall of the fixed frame 32. The end of the push rod 33 away from the fixed frame 32 has a curved surface design. There are seven groups of push rods 33. The seven groups of push rods 33 can make the force rod 37 move reciprocally multiple times, ensuring the number of rotations of the flow disturbance plate 35 and guaranteeing the flow disturbance effect of the flow disturbance plate 35. A flow disturbance plate 35 is rotatably connected to the outer wall of the second support plate 34. A fourth fixed stop 36 is fixedly connected to the outer wall of the second support plate 34. The second support plate 34 supports the rotation of the flow disturbance plate 35, and the rotation range of the flow disturbance plate 35 is limited by the fourth fixed stop 36.
[0027] Furthermore, one end of the spoiler 35 is fixedly connected to a force-receiving rod 37, and the other end of the spoiler 35 is fixedly connected to a second compression spring 38. The end of the second compression spring 38 away from the spoiler 35 is welded to the inner wall of the fuse body 1. The force-receiving rod 37 can be pushed by the movable push rod 33, thereby driving the spoiler 35 to rotate on the second support plate 34. At the same time, the second compression spring 38 is compressed. When the push rod 33 leaves the surface of the force-receiving rod 37, through the reset of the second compression spring 38, the spoiler 35 is reset, and the spoiler 35 performs the spoiler work, which is convenient for accelerating the air circulation inside the fuse body 1 and facilitating rapid heat dissipation. Since the moving speed of the energy storage block 47 is increased, the moving speed of the first curved rod 31 is driven to increase, so that the push rod 33 can continuously push the force-receiving rod 37, thereby improving the continuity of the spoiler work of the spoiler 35 and ensuring that the spoiler 35 can better drive the air inside the fuse body 1 for spoiler work, and cooperating with the ventilation port 12 to improve the heat dissipation effect.
[0028] Furthermore, a second curved rod 10 is fixedly connected to the top of the energy storage seat 46. A connecting rod 11 is hinged to the outer wall of the second curved rod 10. A ventilation port 12 is provided on the fuse body 1. A wind shield 13 is rotatably connected to the outer wall of the fuse body 1. By one end of the energy storage seat 46, the second curved rod 10 is driven to move. The movement of the second curved rod 10 will drive the connecting rod 11 to move. The wind shield 13 can block the ventilation port 12. A guiding seat 14 is fixedly connected to the inner wall of the ventilation port 12. A push rod 15 is slidably connected to the inner wall of the guiding seat 14. The end of the connecting rod 11 away from the second curved rod 10 is hinged to the outer wall of the push rod 15. The guiding seat 14 guides the moving direction of the push rod 15. The movement of the connecting rod 11 drives the push rod 15 to slide on the inner wall of the guiding seat 14. The push rod 15 pushes the wind shield 13, thereby causing the wind shield 13 to rotate, facilitating the opening of the ventilation port 12, and cooperating with the spoiler structure 3 for rapid heat dissipation work.
[0029] In the present invention, during use, when the temperature of the fuse body 1 rises, the airbag 43 will expand. Then, the expansion of the airbag 43 squeezes the movable disk 44, causing the movable disk 44 to slide on the inner wall of the air cylinder 42. The movement of the movable disk 44 drives the sliding rod 45 and the energy storage seat 46 to move synchronously. The movement of the energy storage seat 46 drives the energy storage block 47 to slide in the energy storage groove. When the fixed stop block 1-5 on the energy storage block 47 contacts the fixed stop block 2-8 on the rotating rod 7, the fixed stop block 2-8 blocks the fixed stop block 1-5, causing the fixed stop block 1-5 to stop moving, and the energy storage block 47 also stops moving synchronously. As a result, the compression spring 1-48 is compressed to perform the energy storage work. At this time, the energy storage seat 46 continues to move. When the energy storage seat 46 moves to a certain position, the fixed stop block 3-9 on the energy storage seat 46 squeezes the rotating rod 7, causing the rotating rod 7 to rotate around the fixed axis on the fixed rod 6. Then, the fixed stop block 2-8 on the rotating rod 7 moves away from the fixed stop block 1-5 on the energy storage block 47, separating the two and releasing the energy storage state of the energy storage block 47. The compressed compression spring 1-48 automatically resets, driving the energy storage block 47 and the first curved rod 31 to move quickly. Then, the fixed frame 32 and the pushing rod 33 move quickly; In addition, the continuously moving pushing rod 33 pushes the force-receiving rod 37 to move, driving the spoiler 35 to rotate on the second support plate 34. At the same time, the compression spring 2-38 is compressed. When the pushing rod 33 leaves the surface of the force-receiving rod 37, the compression spring 2-38 resets, causing the spoiler 35 to reset and perform the spoiler work, which is convenient for accelerating the air circulation inside the fuse body 1 and improving the heat dissipation effect of the device. At the same time, the movement of the energy storage seat 46 drives the second curved rod 10 and the connecting rod 11 to move. The movement of the connecting rod 11 drives the pushing rod 15 to slide in the guide seat 14. Then, the pushing rod 15 pushes the wind deflector 13 to rotate, opening the ventilation opening 12. Through the opening of the ventilation opening 12 and the spoiler work of the spoiler 35, rapid heat dissipation is jointly achieved, effectively reducing the temperature of the fuse body 1.
