Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic grid-connected control boxes, in particular to a photovoltaic grid-connected control box with an anti-collision function. Background Art

[0002] With the continuous development of solar photovoltaic power generation technology, photovoltaic grid-connected systems are increasingly used in the energy field. As a key device in the system, the photovoltaic grid-connected control box is responsible for the precise management of the conversion, distribution and control of electric energy, ensuring that the photovoltaic power generation system can stably and efficiently convert solar energy into electric energy and connect it to the grid. It plays a vital role in various photovoltaic power stations, distributed photovoltaic power generation projects and other scenarios, and its normal operation is directly related to the performance and benefits of the entire photovoltaic grid-connected system. However, in actual applications, photovoltaic grid-connected control boxes often face many challenges.

[0003] Photovoltaic grid-connected control boxes are usually installed outdoors or in more complex environments and are vulnerable to impacts from various external forces. Some existing control boxes are relatively weak in anti-collision design and lack effective protection measures. When impacted, the control box is easily damaged, causing damage to internal electronic components, which in turn causes equipment failure, increases maintenance costs and downtime, and seriously affects the normal operation of the photovoltaic grid-connected system.

[0004] To this end, we proposed a photovoltaic grid-connected control box with anti-collision function. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a photovoltaic grid-connected control box with an anti-collision function, which is used to solve the above-mentioned technical defects.

[0006] To achieve the above purpose, the present invention is implemented by the following technical solutions: a photovoltaic grid-connected control box with an anti-collision function, comprising a control box, a fixing frame and a mounting frame, wherein the control box is fixedly arranged on the front of the fixing frame, and the mounting frame is also fixedly arranged above the front of the fixing frame; Both sides of the front of the fixing frame are movably provided with protection components, and both sides of the mounting frame are fixedly provided with radar sensors; The control box can be protected from collision by the protective components movably arranged on both sides of the front of the fixing frame. When the control box may be hit by external force, the protective components can absorb and disperse the impact force, thereby effectively protecting the control box from damage. This greatly improves the safety and stability of the control box during operation and reduces equipment failures and maintenance costs caused by accidental impacts. In addition, radar sensors are fixed on the front and both sides of the mounting frame. The radar sensors can monitor the environment around the control box in real time. When an object is detected approaching the control box, an early warning signal can be issued in time to alert relevant personnel to avoid collision accidents. The active anti-collision design further improves the safety performance of the control box, providing double protection for its stable operation.

[0007] The protective assembly includes a protective frame, protective frames are slidably provided on both sides of the front of the fixing frame, an upper sliding groove is provided on the front side of the bottom of the mounting frame, and a lower sliding groove is provided at the bottom of the front of the fixing frame, the tops of the two protective frames are slidably connected to the inside of the upper sliding groove, sliding blocks are fixedly provided at the bottom of the backs of the two protective frames, and the two sliding blocks are located at both sides of the lower sliding groove and are slidably connected, two positioning holes are provided in the middle of the bottom of the fixing frame, and the tops of the two positioning holes extend to the inside of the two sliding blocks respectively, a locking block is movably provided in the middle of the bottom of the fixing frame, and positioning columns are fixedly provided on both sides of the top of the locking block, the tops of the two positioning columns extend to the inside of the positioning holes at the bottom of the two sliding blocks respectively, and the top of the locking block is movably connected to the bottom of the fixing frame through a lock.

[0008] Preferably, a protective strip is fixedly provided inside the protective frame, and the protective strip is made of a thermoplastic elastomer material. A protective shell is slidably provided on the outer peripheral surface of the protective frame, and a plurality of honeycomb grooves are provided inside the protective shell.

[0009] Preferably, rotation grooves are provided at the upper and lower parts of the protection frame, and the top and the bottom of the back side of the protection shell are respectively located inside the two rotation grooves and are slidably connected.

[0010] Preferably, a servo motor is fixedly arranged at the lower part of the protective frame, and a connecting rod is fixedly arranged on the output shaft of the servo motor, and one end of the connecting rod is fixedly connected to the bottom of the back side of the protective shell.

[0011] When the control box is protected, a radar sensor is used to monitor the environment around the control box in real time. When an object is detected approaching the control box, a warning signal can be promptly sent to the controller of the servo motor. The output shaft of the servo motor is used to control the connecting rod to rotate inside the protective frame. The connecting rod drives the protective shell to rotate on the outer surface of the protective frame. The rotating protective shell disperses the impact force in different directions, converting the impact force into rotational kinetic energy, thereby reducing the direct impact on the control box.

[0012] Preferably, shock-absorbing frames are fixedly installed inside the two protective frames, and foam pads are fixedly installed on the front sides of the two shock-absorbing frames, a plurality of damper springs are fixedly installed on the back sides of the inner walls of the shock-absorbing frames, and buffer frames are fixedly installed on the front ends of the plurality of damper springs, and the front sides of the plurality of buffer frames are in contact with the back sides of the foam pads.

[0013] Through the design of the above structure in the present invention, when the control box is hit, the impact force transmitted to the inside of the control box can be greatly reduced through the layers of buffering of the foam pad, buffer frame and damper spring, and can play a good vibration buffering effect on the electronic components and other precision components in the photovoltaic grid-connected control box. The good shock-absorbing structure can reduce the probability of component damage due to impact, extend the service life of the control box, and reduce maintenance costs and the risk of equipment failure.

[0014] Preferably, the outer peripheral surface of the bottom of the mounting frame is provided with a plurality of heat dissipation holes, and the interiors of the plurality of heat dissipation holes are connected with the interior of the control box; by connecting the plurality of heat dissipation holes provided on the outer peripheral surface of the bottom of the mounting frame with the interior of the control box, the heat inside the control box can be dissipated in time, ensuring that the internal electronic components operate normally at an appropriate temperature, preventing performance degradation or damage of the components due to overheating, improving the working stability and reliability of the control box, and extending the service life of the electronic components.

[0015] Preferably, the method of using the photovoltaic grid-connected control box with anti-collision function is as follows: When the control box is protected, the radar sensor is used to monitor the environment around the control box in real time. When an object is detected approaching the control box, a warning signal can be sent to the controller of the servo motor in time. The output shaft of the servo motor is used to control the connecting rod to rotate inside the protective frame. The connecting rod drives the protective shell to rotate on the outer surface of the protective frame. The rotating protective shell disperses the impact force in different directions, converting the impact force into rotational kinetic energy, thereby reducing the direct impact on the control box. A shock-absorbing frame is arranged inside the protective frame. The foam pad on the front of the shock-absorbing frame can first contact the foreign object when it is hit. The foam pad is soft and has good elasticity. It can initially buffer the impact force and play the first layer of protection. When a smaller object hits the control box at a certain speed, the foam pad can absorb part of the energy through its own deformation, thereby reducing the impact of the impact force on the control box. In addition, the shock-absorbing effect is further enhanced by the damper spring and the buffer frame on the back of the inner wall of the shock-absorbing frame. When it is subjected to a larger impact force, the foam pad will transfer the force to the buffer frame, and the buffer frame will squeeze the damper spring. The damper spring can produce corresponding deformation according to the size of the impact force, and convert the impact force into elastic potential energy of the spring, thereby effectively absorbing and dispersing the impact force. The damper spring and the buffer frame form a dynamic shock-absorbing system, which can adapt to impacts of different intensities and ensure the safe use of the control box.

[0016] Compared with the prior art, it has the following beneficial effects: 1. The present invention provides comprehensive protection and good operating conditions for the photovoltaic grid-connected control box through the synergistic effect of various structural designs. In terms of anti-collision, protection is provided from multiple angles and levels, and both slight collisions and large impacts can be effectively dealt with, greatly improving the safety and stability of the control box during operation; the heat dissipation design ensures the normal operating temperature of the internal electronic components, further ensuring the overall performance and service life of the control box, reducing the equipment failures and maintenance costs caused by accidental collisions and overheating for the photovoltaic grid-connected control box, and providing strong support for the stable operation of the photovoltaic grid-connected system.

[0017] 2. In the present invention, the control box can be protected from collision by the protective components movably arranged on both sides of the front of the fixed frame. When the control box may be hit by external force, the protective components can absorb and disperse the impact force, thereby effectively protecting the control box from damage. This greatly improves the safety and stability of the control box during operation and reduces equipment failures and maintenance costs caused by accidental impacts. In addition, by using radar sensors fixed on the front and both sides of the mounting frame, the radar sensors can monitor the environment around the control box in real time. When an object is detected approaching the control box, it can promptly issue an early warning signal to alert relevant personnel to avoid collision accidents. The active anti-collision design further improves the safety performance of the control box, providing double protection for its stable operation.

[0018] 3. In the present invention, the protective strip is made of thermoplastic elastomer material. Since the thermoplastic elastomer has good elasticity and wear resistance, it can absorb part of the impact force when it is hit, play a buffering role, and further protect the control box from direct impact; by arranging a number of honeycomb grooves inside the protective shell, since the honeycomb structure has high strength and stability, it can withstand a large impact force, and the honeycomb grooves can disperse the impact force and transfer it to the surrounding structure, reducing the local pressure on the control box, and the protective shell slides on the outer peripheral surface of the protective frame, increasing the coverage area of ​​the protection and improving the protection effect; in addition, the output shaft of the servo motor controls the connecting rod to rotate inside the protective frame, and the connecting rod drives the protective shell to rotate on the outer peripheral surface of the protective frame. The rotating protective shell can disperse the impact force in different directions and convert the impact force into rotational kinetic energy, thereby greatly reducing the direct impact on the control box, which can effectively improve the safety performance of the control box when facing an impact and reduce the risk of equipment damage.

[0019] 4. In the present invention, a shock-absorbing frame is arranged inside the protective frame. The foam pad on the front of the shock-absorbing frame can first contact the foreign object when it is hit. The foam pad is soft and has good elasticity. It can preliminarily buffer the impact force and play a first-layer protection role. When a smaller object hits the control box at a certain speed, the foam pad can absorb part of the energy through its own deformation, thereby reducing the impact of the impact force on the control box; in addition, the shock-absorbing effect is further enhanced by the damper spring and the buffer frame on the back of the inner wall of the shock-absorbing frame. When it is subjected to a larger impact force, the foam pad will transfer the force to the buffer frame, and the buffer frame will squeeze the damper spring. The damper spring can produce corresponding deformation according to the size of the impact force, and convert the impact force into elastic potential energy of the spring, thereby effectively absorbing and dispersing the impact force. The damper spring and the buffer frame form a dynamic shock-absorbing system, which can adapt to impacts of different intensities and ensure the safe use of the control box.

[0026] It should be noted that when the control box 1 is protected, the radar sensor 9 is used to monitor the environment around the control box 1 in real time. When an object is detected approaching the control box 1, a warning signal can be promptly sent to the controller of the servo motor 15. The output shaft of the servo motor 15 is used to control the connecting rod 14 to rotate inside the protective frame 4.

[0027] In a specific embodiment, the present invention adopts thermoplastic elastomer material for the protective strip 16.

Several damper springs 20 are fixedly installed on the back sides of the inner walls of the shock-absorbing frames 17, and buffer frames 19 are fixedly installed at the front ends of the several damper springs 20. The front sides of the several buffer frames 19 are in contact with the back sides of the foam pads 18.

[0029] It should be noted that, by arranging a shock-absorbing frame 17 inside the protective frame 4, the foam pad 18 on the front of the shock-absorbing frame 17 can first contact the foreign object when it is hit. The foam pad 18 is soft in texture and has good elasticity. It can initially buffer the impact force and play a first-layer protection role. When a smaller object hits the control box 1 at a certain speed, the foam pad 18 can absorb part of the energy through its own deformation, thereby reducing the impact of the impact force on the control box 1; in addition, the damper spring 20 and the buffer frame 19 on the back of the inner wall of the shock-absorbing frame 17 further enhance the shock-absorbing effect. When subjected to a larger impact force, the foam pad 18 will transfer the force to the buffer frame 19, and the buffer frame 19 will squeeze the damper spring 20.

[0030] In a specific embodiment, through the design of the above-mentioned structure in the present invention, when the control box 1 is hit, the impact force transmitted to the inside of the control box 1 can be greatly reduced through the layered buffering of the foam pad 18, the buffer frame 19 and the damper spring 20, and it can have a good vibration buffering effect on the electronic components and other precision components in the photovoltaic grid-connected control box. The good shock-absorbing structure can reduce the probability of component damage due to impact, extend the service life of the control box 1, and reduce the maintenance cost and the risk of equipment failure.

[0032] Embodiment 2: Specifically, this embodiment also discloses a method for using a photovoltaic grid-connected control box with an anti-collision function as follows: When the control box 1 is protected, the radar sensor 9 is used to monitor the environment around the control box 1 in real time. When an object is detected approaching the control box 1, a warning signal can be sent to the controller of the servo motor 15 in time, and the output shaft of the servo motor 15 is used to control the connecting rod 14 to rotate inside the protective frame 4. The connecting rod 14 drives the protective shell 12 to rotate on the outer peripheral surface of the protective frame 4. The rotating protective shell 12 is used to disperse the impact force in different directions, so that the impact force is converted into rotational kinetic energy, thereby reducing the direct impact on the control box 1; A shock absorbing frame 17 is arranged inside the protective frame 4. The foam pad 18 on the front of the shock absorbing frame 17 can first contact the foreign object when it is hit. The foam pad 18 is soft and has good elasticity. It can initially buffer the impact force and play a first-layer protection role. When a smaller object hits the control box 1 at a certain speed, the foam pad 18 can absorb part of the energy through its own deformation, thereby reducing the impact of the impact force on the control box 1; in addition, the damper spring 20 and the buffer frame 19 on the back of the inner wall of the shock absorbing frame 17 further enhance the shock absorbing effect. When it is subjected to a larger impact force, the foam pad 18 will transfer the force to the buffer frame 19, and the buffer frame 19 will squeeze the damper spring 20.
