Description

Technical Field

[0001] The present invention relates to the field of photovoltaic brackets, and in particular to an installation and fixing device for a grid-type photovoltaic energy storage system. Background Art

[0002] The existing grid-type photovoltaic energy storage system has technical problems such as weak earthquake resistance and poor adaptability during installation and fixation. In terms of earthquake resistance, the existing installation and fixation devices show obvious fragility in the face of natural disasters such as earthquakes. Many traditional devices use a simple rigid connection method to fix the energy storage system directly on the foundation structure. When earthquake waves strike, the vibration energy is transmitted to the energy storage equipment without hindrance, causing the precision electronic components and battery pack connection parts inside the photovoltaic energy storage system to loosen, fall off or even be damaged due to severe vibration. This will not only interrupt the normal operation of the photovoltaic energy storage system and cause energy supply interruption, but may also cause permanent damage to the equipment, greatly increase maintenance costs and system downtime, and seriously affect the promotion and application of photovoltaic energy storage systems in earthquake-prone areas.

[0003] In terms of adaptability, the installation environment of photovoltaic energy storage systems is complex and diverse, covering various terrains such as mountains, plains, deserts and wetlands. Traditional installation and fixing devices are often designed in a single design and lack the ability to adapt to different terrains. In areas with large terrain fluctuations such as mountains, it is difficult to ensure that the equipment is always in a horizontal and stable state, which will cause the photovoltaic panels to fail to receive sunlight at the best angle, reduce the power generation efficiency, and the unstable center of gravity of the equipment may also cause safety hazards. In soft ground environments such as deserts, traditional devices are prone to tilting or even collapse due to insufficient foundation support. In addition, in the face of severe weather conditions such as strong winds, heavy rains, and heavy snow, existing installation and fixing devices cannot provide effective protection. Strong winds may blow down the equipment, and heavy rains and heavy snow may cause water to enter the equipment and snow to accumulate, which in turn affects the electrical performance and normal operation of the equipment.

[0004] Moreover, with the continuous expansion of the scale of photovoltaic energy storage systems and the continuous upgrading of technology, the requirements for installation and fixing devices are becoming higher and higher. The existing devices require a lot of manpower, material resources and time for debugging and fixing during the installation process, which increases the construction cost of the system. At the same time, due to the limitations of its design, the operation is difficult and costly during the later maintenance and upgrading of the system. In summary, it is urgent to develop a grid-type photovoltaic energy storage system installation and fixing device with strong seismic resistance and good adaptability, which is of great significance to promoting the widespread application and sustainable development of photovoltaic energy storage technology.

DETAILED DESCRIPTION

[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] refer to Figures 1 to 9 , a mounting and fixing device for a grid-type photovoltaic energy storage system, comprising an energy storage body 1, and also comprising:

[0033] A buffer platform 4 is fixedly connected to the lower end of the energy storage body 1, and a positioning platform 2 is arranged below the buffer platform 4. A plurality of damping rods 5 are arranged on one side of the buffer platform 4 close to the positioning platform 2. One end of the damping rod 5 is fixedly connected to the buffer platform 4, and the other end is fixedly connected to the positioning platform 2. A positioning buffer mechanism 6 is respectively arranged at the four corners of the positioning platform 2. The positioning buffer mechanism 6 includes a pressure regulating seat 16, a pressure regulating cylinder 17, a second motor 19, an active screw 20, a chassis 21, an active screw sleeve 22, an extrusion disk 27, an extrusion spring 31 and a drill bit 33. The pressure regulating seat 16 is arranged above the positioning platform 2, and the pressure regulating cylinder 17 is fixedly connected to the lower end of the pressure regulating seat 16 (such as Fig. 9As shown in the figure, the second motor 19 is connected to the upper end of the pressure regulating seat 16, the active screw 20 is coaxially arranged with the pressure regulating cylinder 17 and is coaxially connected with the output end of the second motor 19, the active screw sleeve 22 is threadedly connected with the active screw 20 and is key-connected with the pressure regulating cylinder 17, the chassis 21 is coaxially connected with the lower end of the active screw 20, the extrusion plate 27 is arranged below the chassis 21 and is slidably connected with the pressure regulating cylinder 17, and the active screw sleeve 22 moves when the extrusion plate 27 is driven to move, and the extrusion spring 31 is arranged below the chassis 21 and moves with the The movement of the extrusion disk 27 causes compression, and the drill bit 33 is arranged below the extrusion spring 31 and rotates with the rotation of the active screw 20. When the active screw 20 rotates, the drill bit 33 is driven by the active screw sleeve 22 to move along the axial direction of the pressure regulating cylinder 17. A center of gravity adjustment mechanism 35 is arranged in the middle of the positioning platform 2. The center of gravity adjustment mechanism 35 includes a load block 36 and a slide seat 40. The load block 36 is adjustably connected to the lower end of the positioning platform 2. The slide seat 40 is arranged at the upper end of the positioning platform 2 and drives the load block 36 to move when moving.

[0034] When installing the device, the operator moves the device to the upper end of the slope, and then adjusts the specific position of the pressure regulating cylinder 17 through the four positioning buffer mechanisms 6. Figure 1 During this process, the first motor 7 starts to drive the pressure regulating tube 17 to move in the vertical direction. During the displacement of the pressure regulating tube 17, the drill bit 33 will first contact the slope, and the extrusion spring 31 will be compressed. The contact between the drill bit 33 and the slope is a non-rigid contact, and the positioning platform 2 and the slope complete the initial positioning. Then the second motor 19 starts and drives the active screw 20 to rotate. The active screw 20 drives the active screw sleeve 22 threadedly connected to it to move. The movement of the active screw sleeve 22 can drive the extrusion spring 31 to be compressed through the extrusion disk 27. At the same time, the rotation of the active screw 20 will also drive the drill bit 33 to rotate. At this time, the drill bit 33 rotates while breaking the soil layer of the slope under the action of the extrusion spring 31 until the drill bit 33 is completely drilled into the slope. At this time, the rigid positioning of the positioning platform 2 is completed.

[0035] After the four drill bits 33 are positioned, the operator can adjust the specific position of the slide 40 to change the position of the weight block 36 to ensure that the center of gravity of the device is maintained in a balanced position. When an earthquake occurs, several damping rods 5 will buffer the vibration to ensure that the energy storage body 1 connected to the buffer platform 4 remains stable.

[0036] In order to change the position of the pressure regulating cylinder 17 in the vertical direction so as to adapt to slopes of different inclinations, the following features are also specifically provided:

[0037] The positioning buffer mechanism 6 also includes a first motor 7, a first bevel gear 8, a bevel gear rack 9, a second bevel gear 10, a main gear 11, a bidirectional gear ring 12, two driven gears 13, two driven screws 14 and two driven screw sleeves 15. The first motor 7 is fixedly connected to the lower end of the positioning platform 2 (such as Figure 3 As shown), the bevel gear rack 9 is arranged beside the first motor 7 and is fixedly connected to the positioning platform 2, the first bevel gear 8 is rotatably connected to the bevel gear rack 9 and is coaxially fixedly connected to the output end of the first motor 7, the second bevel gear 10 is rotatably connected to the bevel gear rack 9 and meshes with the first bevel gear 8, the main gear 11 is rotatably arranged at the upper end of the positioning platform 2 and is coaxially fixedly connected to the second bevel gear 10, the bidirectional gear ring 12 is coaxially arranged with the pressure regulating cylinder 17 and meshes with the main gear 11, the two driven gears 13 are rotatably arranged on one side of the bidirectional gear ring 12 close to the center of the circle, the driven gear 13 is meshed with the bidirectional gear ring 12, the two driven screws 14 are coaxially arranged with the two driven gears 13, the driven screw 14 is coaxially fixedly connected with the driven gear 13, the two driven screw sleeves 15 are respectively threadedly connected with the two driven screws 14, and the driven screw sleeves 15 are fixedly connected to the pressure regulating seat 16. When it is necessary to adjust the position of the pressure regulating cylinder 17 in the vertical direction to adapt to slopes of different inclinations, the first motor 7 is started. The output end of the first motor 7 drives the first bevel gear 8 coaxially connected thereto to rotate, and the first bevel gear 8 meshes with the second bevel gear 10, thereby driving the second bevel gear 10 to rotate. The second bevel gear 10 in turn drives the main gear 11 coaxially connected thereto to rotate, and the main gear 11 meshes with the bidirectional gear ring 12, thereby causing the bidirectional gear ring 12 to rotate. The bidirectional gear ring 12 meshes with two driven gears 13 at the same time, driving the driven gear 13 to rotate. Since the driven screw 14 is coaxially connected to the driven gear 13, the driven screw 14 rotates accordingly, and the driven screw sleeve 15 threadedly connected to the driven screw 14 drives the pressure regulating seat 16 and the pressure regulating cylinder 17 connected thereto to move in the vertical direction under the action of the thread transmission, thereby realizing the precise adjustment of the position of the pressure regulating cylinder 17 to adapt to different terrain conditions.

[0038] In order to realize that when the chassis 21 moves, the chassis 21 will drive the extrusion plate 27 to move, the following features are specifically set:

[0039] The positioning buffer mechanism 6 also includes a plurality of connecting rods 26. The side wall of the pressure regulating cylinder 17 is formed with a plurality of limiting grooves 18 (such as Fig. 9As shown in the figure, a plurality of connecting rods 26 are respectively slidably connected with a plurality of limiting grooves 18, the upper end of the connecting rod 26 is fixedly connected with the active screw sleeve 22, and the lower end is fixedly connected with the extrusion plate 27. When the active screw sleeve 22 moves along the axial direction of the pressure regulating cylinder 17 driven by the active screw rod 20, the active screw sleeve 22 can drive the extrusion plate 27 to move synchronously through the connecting rod 26. The limiting groove 18 limits the movement trajectory of the connecting rod 26, ensuring that the extrusion plate 27 always remains stable during the movement process, and can accurately move with the movement of the active screw sleeve 22, thereby realizing the effective compression operation of the extrusion spring 31, and ensuring the stability and reliability of the positioning buffer mechanism 6 during the working process.

[0040] In order to limit the movement of the active screw sleeve 22, the following features are also specifically provided:

[0041] The positioning buffer mechanism 6 also includes a top plate 23, a plurality of limiting sleeves 24 and a plurality of limiting rods 25. The top plate 23 is arranged below the second motor 19 and is fixedly connected to the pressure regulating tube 17. The plurality of limiting sleeves 24 are arranged in an array at equal angles along the circumferential direction of the lower end of the top plate 23. The limiting sleeve 24 is fixedly connected to the top plate 23. The plurality of limiting rods 25 are respectively key-connected to the plurality of limiting sleeves 24. The limiting rod 25 is fixedly connected to the upper end of the active screw sleeve 22. The limiting sleeve 24 limits the movement of the limiting rod 25, prevents the active screw sleeve 22 from deflecting or shaking during the movement, ensures that the active screw sleeve 22 can move smoothly along the axial direction of the pressure regulating tube 17, and thus ensures that the extrusion plate 27 can accurately compress the extrusion spring 31.

[0042] In order to realize that during the rotation of the active screw 20, the drill bit 33 can also rotate while moving relative to the active screw 20 to break the soil layer, the following features are specifically provided:

[0043] The positioning buffer mechanism 6 also includes a squeeze sleeve 28, a squeeze rod 29, an upper plate 30 and a lower plate 32. The upper plate 30 is rotatably connected to the lower end of the squeeze sleeve 27, the lower plate 32 is rotatably connected to the upper end of the drill bit 33, the upper end of the squeeze spring 31 is fixedly connected to the upper plate 30, and the lower end is fixedly connected to the lower plate 32. The squeeze sleeve 28 is coaxially arranged with the squeeze spring 31 and is coaxially fixedly connected to the lower end of the chassis 21. The squeeze rod 29 is key-connected with the squeeze sleeve 28 and is fixedly connected to the upper end of the lower plate 32. When the active screw 20 rotates and drives the chassis 21 to rotate, the chassis 21 drives the drill bit 33 to rotate through the squeeze sleeve 28 and the squeeze rod 29. At the same time, the squeeze spring 31 plays a role of buffering and transmitting force between the upper plate 30 and the lower plate 32. When the drill bit 33 contacts the soil layer, the squeeze spring 31 will be compressed due to being squeezed. At this time, the active screw 20 continues to rotate, and the drill bit 33 breaks the soil layer while rotating along with the movement of the active screw 20.

[0044] The arrangement of the extrusion sleeve 28 and the extrusion rod 29 ensures that the force can be transmitted stably during the movement of the drill bit 33, and enables the drill bit 33 to rotate while moving with the active screw 20, thereby effectively breaking the soil layer and improving the working efficiency of the positioning buffer mechanism 6 under different terrain conditions.

[0045] In order to adaptively protect the movement of the squeeze plate 27, the following features are also specifically provided:

[0046] The positioning buffer mechanism 6 also includes a bellows 34, which is sleeved on the outside of the pressure regulating cylinder 17, with the lower end of the bellows 34 fixedly connected to the outer wall of the pressure regulating cylinder 17, and the upper end of the bellows 34 fixedly connected to the extrusion disk 27. The bellows 34 will expand or contract with the movement of the extrusion disk 27. The bellows 34 can prevent external dust, debris, etc. from entering the gap between the extrusion disk 27 and the pressure regulating cylinder 17, and avoid the normal movement of the extrusion disk 27 being affected by the accumulation of debris. At the same time, when the device is subjected to vibration or external force impact, the bellows 34 can also play a certain buffering role, maintain the structural integrity of the extrusion disk 27 and the pressure regulating cylinder 17, extend the service life of the positioning buffer mechanism 6, and ensure that it can work stably in complex environments.

[0047] In order to realize the movement of the load block 36, the connection structure between the load block 36 and the slide seat 40 is supplemented, and the following features are specifically set:

[0048] The center of gravity adjustment mechanism 35 further includes a curved plate 38, two bolts 39 and two first slide rails 37. The two first slide rails 37 are respectively fixedly connected to the lower end of the positioning platform 2 (such as Figure 4 As shown in the figure, the two sides of the load block 36 are respectively slidably connected to the two first slide rails 37, one end of the curved plate 38 is fixedly connected to the side wall of the load block 36, and the other end is fixedly connected to two bolts 39. Two strip through holes 3 are formed in the middle of the positioning platform 2, and the bolts 39 are fixedly connected to the slide seat 40 after passing through the strip through holes 3. The movement of the slide seat 40 will drive the curved plate 38 connected to it by the bolts 39 to move (the specific movement process of the slide seat 40 will be described in detail later), and the curved plate 38 is fixedly connected to the load block 36, thereby driving the load block 36 to slide on the first slide rail 37. The first slide rail 37 provides a guide for the movement of the load block 36 to ensure that the load block 36 can move smoothly. The strip through hole 3 provides space for the movement of the bolt 39, so that the slide seat 40 can accurately adjust the position of the load block 36 through the bolt 39 during the movement, realize the precise adjustment of the center of gravity of the device, and improve the stability of the device under different terrain conditions.

[0049] In order to drive the slide 40 to move, the following features are also specifically provided:

[0050] The center of gravity adjustment mechanism 35 also includes a turning handle 44, a secondary screw rod 42, a secondary screw sleeve 43, two second slide rails 41 and two screw seats 45. The two second slide rails 41 are respectively arranged on both sides of the slide seat 40 (such as Figure 6 As shown in the figure, the second slide rail 41 is fixedly connected to the positioning platform 2 and is slidably connected to the slide seat 40, the secondary screw sleeve 43 is fixedly connected to the slide seat 40, the secondary screw 42 is threadedly connected to the secondary screw sleeve 43, and two screw seats 45 are respectively arranged at both ends of the secondary screw 42 and are fixedly connected to the upper end of the positioning platform 2, the screw seat 45 is rotationally connected to the secondary screw 42, and the turning handle 44 is coaxially fixedly connected to one end of the secondary screw 42. When it is necessary to drive the slide seat 40 to move, the operator turns the turning handle 44. The turning handle 44 drives the secondary screw 42 to rotate, and under the action of the thread transmission, the secondary screw 42 will drive the secondary screw sleeve 43 to move, and the secondary screw sleeve 43 will drive the slide seat 40 to move along the second slide rail 41. The second slide rail 41 provides guidance for the movement of the slide seat 40 to ensure that the slide seat 40 can move smoothly. The screw seat 45 supports and positions the secondary screw 42 to ensure the stability of the secondary screw 42 during rotation. By turning the handle 44, the position of the slide 40 can be adjusted conveniently and accurately, thereby adjusting the position of the weight block 36 and completing the adjustment of the center of gravity of the device to adapt to different installation environments and working conditions.

[0051] The working principle of this device is that when facing different installation scenarios, its anti-seismic and terrain adaptation functions work together. First, in terms of terrain adaptation, when the device is moved to complex terrain such as a slope, the positioning buffer mechanism 6 starts to operate. Start the first motor 7, and through the transmission of a series of bevel teeth, gears and screw sleeves, accurately adjust the vertical position of the pressure regulating cylinder 17 so that the drill bit 33 can smoothly contact the slope ground. At this time, the extrusion spring 31 plays a buffering role to avoid the rigid collision between the drill bit 33 and the slope. Then start the second motor 19, and the active screw 20 rotates. On the one hand, it drives the active sleeve 22 and the extrusion disk 27 to move the compression extrusion spring 31, and on the other hand, it makes the drill bit 33 rotate. Under the action of the extrusion spring 31, the drill bit 33 gradually drills into the slope soil layer, realizing the rigid positioning of the positioning platform 2, and ensuring that the device is stably fixed on the slope.

[0052] In terms of earthquake resistance, when an earthquake or other vibration occurs, the damping rod 5 under the positioning platform 2 plays a key role. One end of the damping rod 5 is fixedly connected to the buffer platform 4, and the other end is fixedly connected to the positioning platform 2. When the energy generated by the vibration is transmitted to the damping rod 5, the damping mechanism inside the damping rod 5 starts to work, converting the kinetic energy of the vibration into other forms of energy and consuming it, thereby effectively reducing the impact of the vibration on the positioning platform 2 and the energy storage body 1 connected thereto, greatly reducing the risk of damage to the equipment due to vibration.

[0053] At the same time, the device also has a center of gravity adjustment function. When the device is installed on a non-horizontal terrain such as a slope, the auxiliary screw 42 is driven to rotate by turning the handle 44, thereby causing the auxiliary screw sleeve 43 and the slide 40 connected thereto to move on the second slide rail 41. The slide 40 drives the load block 36 to move on the first slide rail 37 through the bolt 39 and the curved plate 38, thereby adjusting the center of gravity position of the device to ensure that the device always remains balanced and stable under different terrain conditions. Whether facing complex terrain or vibration conditions such as earthquakes, this device can effectively improve the stability and reliability of the installation and fixation of the grid-type photovoltaic energy storage system through the coordinated work of various parts of the structure, and ensure the normal operation of the system.

[0054] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
