Description
Technical Field
[0001] The utility model relates to the technical field of bracket buffering and limiting devices, in particular to a bracket buffering and limiting device. Background Art
[0002] With the transformation of the global energy structure and the popularization of the concept of sustainable development, solar photovoltaic technology, as a clean and renewable energy utilization method, has received widespread attention and application. As an important component of the solar photovoltaic system, the stability and durability of photovoltaic brackets are crucial to the long-term operation and maintenance of the photovoltaic system.
[0003] When using the current bracket buffer limit device, staff often find that: traditional photovoltaic brackets usually adopt a rigid structure. Although it can ensure the stability and safety of photovoltaic modules to a certain extent, in actual applications, especially in complex and changeable climatic environments and geographical conditions, the limitations of rigid brackets gradually become apparent. For example, when natural disasters such as strong winds occur, rigid brackets are often difficult to effectively buffer external impacts, resulting in damage or even falling off of photovoltaic modules, seriously affecting the normal operation of the photovoltaic system. Utility Model Content
[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a bracket buffer limit device.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a bracket buffer limit device, including a support frame, a buffer structure is provided on the support frame, and the buffer structure is mainly composed of two buffer plates, the two buffer plates are respectively arranged on both sides of the support frame, a rubber pad is fixedly connected to the buffer plate, a connecting block is provided on the buffer plate, and a slide groove is respectively provided on both sides of the support frame, two sliders are slidably connected in the slide groove, two connecting rods are rotatably connected to the slider, the connecting rod is rotatably connected to the connecting block, a spring is provided in the slide groove, and the two ends of the spring are respectively fixedly connected to the two sliders.
[0006] The effect achieved by the above components is: when the buffer plate is impacted by foreign objects or strong natural winds, the rubber pad will deform to absorb part of the kinetic energy, and the buffer plate will be pushed to drive the connecting rod to rotate, causing the two sliders to slide away from each other, thereby causing the spring to deform and stretch, further absorbing kinetic energy, thereby reducing the impact on the support frame, thereby avoiding the situation where the rigid bracket is often unable to effectively buffer external impacts when natural disasters such as strong winds occur, causing the photovoltaic components to be damaged or even fall off, seriously affecting the normal operation of the photovoltaic system.
[0007] Preferably, a damping rod is fixedly connected to the two sliding blocks, and the spring is sleeved on the damping rod.
[0008] The effect achieved by the above components is that after the spring is deformed, it will immediately reset and release the stored energy, which may cause vibration. At this time, the damping rod converts the energy released by the spring into heat energy through internal friction, thereby reducing the amplitude and duration of the vibration.
[0009] Preferably, a steel wire rope is fixedly connected to the two sliders.
[0010] The effect achieved by the above components is that the length of the straightened wire rope is less than the length of the fully stretched spring, which can prevent the spring from losing its elasticity and being straightened when the tension is too large.
[0011] Preferably, both ends of the buffer plate are fixedly connected with magnetic blocks, and the two contacting surfaces of the two corresponding magnetic blocks on the two buffer plates are attracted to each other by opposite poles.
[0012] The effect achieved by the above components is: the two corresponding magnetic blocks are attracted together under the action of magnetic force, and the two buffer plates are connected together. Since the connection is in the shape of a sharp angle protruding outward, when wind blows towards the connection between the two buffer plates, the wind will be dispersed to the inclined surfaces of the two buffer plates, reducing the impact on both sides. When only the front side of a buffer plate is impacted, since the two buffer plates are connected together, the two damping rods and springs can work together, one spring contracts, and the other spring stretches.
[0013] Preferably, a mounting structure is provided on the connecting block, and the mounting structure mainly consists of a mounting groove. The mounting groove is opened on the connecting block, and the buffer plate is fixedly connected to the mounting block.
[0014] The effect achieved by the above components is that the buffer plate and the connecting block can be connected together by snapping the mounting block into the corresponding mounting slot, and vice versa, the buffer plate can be easily disassembled so that it can be replaced when it is damaged.
[0015] Preferably, a rectangular groove is provided in the installation groove, and two sliding blocks are slidably connected in the rectangular groove.
[0016] The effect achieved by the above components is: after the mounting block is inserted into the mounting groove, the two sliding blocks are slid so that the two sliding blocks clamp the mounting block, making the installation more stable.
[0017] Preferably, a clamping block is fixedly connected to the sliding block, and clamping slots are respectively provided on the upper and lower surfaces of the mounting block, and the clamping block is adapted to the size of the clamping slots.
[0018] The effect achieved by the above components is that the two card blocks are respectively inserted into the corresponding card slots, which can make the connection more stable.
[0019] Preferably, a bidirectional screw is rotatably connected in the rectangular groove, the two sections of thread on the bidirectional screw are in opposite directions, the bidirectional screw is threadedly connected to the two sliding blocks, a motor is fixedly connected to the connecting block, and the output shaft of the motor is fixedly connected to the bidirectional screw.
[0020] The effect achieved by the above components is: when the motor is started, the output shaft of the motor drives the bidirectional screw to rotate. Since the sliding block slides within the rectangular groove, rotating the bidirectional screw can drive the two sliding blocks to slide synchronously in opposite directions, making the operation more convenient.
[0021] Compared with the prior art, the advantages and positive effects of the present invention are that, in the present invention, by setting a buffer structure, when the buffer plate is impacted by foreign objects or natural strong winds, the rubber pad will deform to absorb part of the kinetic energy, and the buffer plate will be pushed to drive the connecting rod to rotate, so that the two sliders slide away from each other, thereby causing the spring to deform and stretch, further absorbing kinetic energy, thereby reducing the impact on the support frame. After the spring is deformed, it will immediately reset and release the stored energy, which may cause vibration. At this time, the damping rod converts the energy released by the spring into heat energy through internal friction, thereby reducing the amplitude and duration of the vibration. The straightened length of the wire rope is less than the fully stretched length of the spring, which can prevent the spring from being pulled under tension. When it is too large, it will lose its elasticity and be straightened, and the two corresponding magnetic blocks will be attracted together under the action of magnetic force, and the two buffer plates can be connected together. Since the connection is a sharp angle protruding outward, when the wind blows towards the connection between the two buffer plates, the wind will be dispersed to the inclined surfaces of the two buffer plates, reducing the impact on both sides. When only the front of a buffer plate is impacted, since the two buffer plates are connected together, the two damping rods and springs can work together, one spring contracts, and the other spring stretches, thereby avoiding the situation where the rigid bracket is often difficult to effectively buffer external impacts when natural disasters such as strong winds occur, causing the photovoltaic components to be damaged or even fall off, seriously affecting the normal operation of the photovoltaic system.

DETAILED DESCRIPTION
[0027] Example 1, as Figure 1 As shown, a bracket buffering and limiting device includes a support frame 1.
[0028] Reference Figures 1 to 3, a buffer structure 2 is provided on the support frame 1, and the buffer structure 2 is mainly composed of two buffer plates 21. The two buffer plates 21 are respectively arranged on both sides of the support frame 1, and a rubber pad is fixedly connected to the buffer plate 21. A connecting block 25 is provided on the buffer plate 21. A slide groove 22 is respectively provided on both sides of the support frame 1. Two sliders 23 are slidably connected in the slide groove 22. Two connecting rods 24 are rotatably connected to the slider 23. The connecting rod 24 is rotatably connected to the connecting block 25. A spring 27 is provided in the slide groove 22, and the two ends of the spring 27 are respectively fixedly connected to the two sliders 23. When the plate 21 is impacted by foreign objects or strong natural winds, the rubber pad will deform to absorb part of the kinetic energy, and the buffer plate 21 will be pushed to drive the connecting rod 24 to rotate, so that the two sliders 23 slide away from each other, thereby causing the spring 27 to deform and stretch, further absorbing kinetic energy, thereby reducing the impact on the support frame 1, thereby avoiding the situation that when natural disasters such as strong winds occur, the rigid bracket is often difficult to effectively buffer external impacts, causing the photovoltaic components to be damaged or even fall off, seriously affecting the normal operation of the photovoltaic system. The two sliders 23 are fixedly connected with a damping rod 26, which is elastic. The spring 27 is sleeved on the damping rod 26. After the spring 27 is deformed, it will immediately reset and release the stored energy, which may cause vibration. At this time, the damping rod 26 converts the energy released by the spring 27 into heat energy through internal friction, thereby reducing the amplitude and duration of the vibration. The two sliders 23 are fixedly connected with a wire rope 28. The straightened length of the wire rope 28 is less than the fully stretched length of the spring 27, which can prevent the spring 27 from losing its elasticity and being straightened when the tension is too large. The two ends of the buffer plate 21 are respectively fixedly connected with magnetic blocks 29. The two corresponding ones on the two buffer plates 21 The two contacting surfaces of the magnetic block 29 are oppositely polarized and attracted to each other. The corresponding two magnetic blocks 29 are attracted to each other under the action of magnetic force, and the two buffer plates 21 can be connected together. Since the connection is a sharp angle protruding outward, when the wind blows towards the connection between the two buffer plates 21, the wind will be dispersed to the inclined surfaces of the two buffer plates 21, reducing the impact on both sides. When only the front side of a buffer plate 21 is impacted, since the two buffer plates 21 are connected together, the two damping rods 26 and the spring 27 can work together, one spring 27 contracts, and the other spring 27 stretches.
[0029] Reference Figure 1 and Figure 4, a mounting structure 3 is provided on the connecting block 25, and the mounting structure 3 is mainly composed of a mounting groove 31. The mounting groove 31 is opened on the connecting block 25, and a mounting block 32 is fixedly connected to the buffer plate 21. By inserting the mounting block 32 into the corresponding mounting groove 31, the buffer plate 21 can be connected to the connecting block 25. Conversely, the buffer plate 21 can be easily disassembled so that it can be replaced when it is damaged. A rectangular groove 33 is opened in the mounting groove 31, and two sliding blocks 34 are slidably connected in the rectangular groove 33. After the mounting block 32 is inserted into the mounting groove 31, the two sliding blocks 34 are slid so that the two sliding blocks 34 clamp the mounting block 32, making the installation more stable. A clamping block 35 is fixedly connected to the sliding block 34. Slots 36 are respectively provided on the upper and lower surfaces of the mounting block 32. The block 35 is adapted to the size of the slot 36. The two blocks 35 are respectively inserted into the corresponding slots 36 to make the connection more stable. A bidirectional screw 37 is rotatably connected in the rectangular groove 33. The two sections of thread on the bidirectional screw 37 are in opposite directions. The bidirectional screw 37 is threadedly connected to the two sliding blocks 34. A motor 38 is fixedly connected to the connecting block 25. The output shaft of the motor 38 is fixedly connected to the bidirectional screw 37. When the motor 38 is started, the output shaft of the motor 38 drives the bidirectional screw 37 to rotate. Since the sliding block 34 slides within a limited position in the rectangular groove 33, rotating the bidirectional screw 37 can drive the two sliding blocks 34 to slide synchronously in opposite directions, making operation more convenient.
[0030] The working principle is that when the buffer plate 21 is impacted by foreign objects or strong natural winds, the rubber pad will deform to absorb part of the kinetic energy, and the buffer plate 21 will be pushed to drive the connecting rod 24 to rotate, so that the two sliders 23 slide away from each other, thereby causing the spring 27 to deform and stretch, further absorbing kinetic energy, thereby reducing the impact on the support frame 1, thereby avoiding the situation that when natural disasters such as strong winds occur, the rigid bracket is often difficult to effectively buffer the external impact, which causes the photovoltaic components to be damaged or even fall off, seriously affecting the normal operation of the photovoltaic system, the spring 27 will immediately reset and release the stored energy after deformation, which may cause vibration, at this time the damping rod 26 converts the energy released by the spring 27 into heat energy through internal friction, thereby reducing the amplitude and duration of the vibration, the straightened length of the wire rope 28 is less than the fully stretched length of the spring 27, which can prevent the spring 27 from losing its elasticity and being straightened when the tension is too large, and the corresponding two magnetic blocks 29 are attracted together under the action of magnetic force, so that the two buffer plates 21 can be connected together, and because the connection is a pointed angle protruding outward, When the wind blows toward the connection between the two buffer plates 21, the wind will be dispersed to the inclined surfaces of the two buffer plates 21, reducing the impact on both sides. When only the front side of the buffer plate 21 is impacted, since the two buffer plates 21 are connected together, the two damping rods 26 and the springs 27 can work together, one spring 27 contracts, and the other spring 27 stretches, and the mounting block 32 is inserted into the corresponding mounting groove 31, so that the buffer plate 21 and the connecting block 25 can be connected together. Conversely, the buffer plate 21 can be easily disassembled so that When it is damaged, it is replaced. After the mounting block 32 is inserted into the mounting groove 31, the two sliding blocks 34 are slid so that the two sliding blocks 34 clamp the mounting block 32, making the installation more stable. The two clamping blocks 35 are respectively clamped into the corresponding clamping grooves 36 to make the connection more stable. The motor 38 is started, and the output shaft of the motor 38 drives the bidirectional screw 37 to rotate. Since the sliding block 34 slides in a limited position in the rectangular groove 33, rotating the bidirectional screw 37 can drive the two sliding blocks 34 to slide synchronously in opposite directions, making the operation more convenient.
