Description

Technical Field

[0001] The utility model relates to the fields of viscous damping technology and mechanical technology, in particular to a damping bearing with a clamping function and a photovoltaic component. Background Art

[0002] During the operation of the photovoltaic tracking bracket, the photovoltaic tracking structure components installed on the main beam are easily affected by natural factors, such as wind, snow, dust and other weather conditions. At the same time, with the application of high-power photovoltaic modules, the span of photovoltaic modules increases and the flexibility increases, making them more sensitive to wind force and more susceptible to wind-induced dynamic effects. These effects include buffeting (random vibration), vortex vibration (vibration caused by vortices formed when wind flows through the structure) and flutter (self-excited vibration caused by the interaction between structural elasticity and aerodynamic force). These vibrations will not only damage the bracket structure, but may also damage the photovoltaic modules themselves, leading to service interruption and economic losses.

[0003] To solve this problem, the prior art provides the following three solutions:

[0004] (1) A set of damping rods is added to the main square tubes on both sides of the tracking bracket. When strong winds hit, the damping rods provide reaction force to resist wind pressure.

[0005] (2) The pin is placed in a viscous liquid. When the bracket needs to adjust its direction to track the sun, the rotation of the pin in the liquid will produce a damping effect.

[0006] (3) A damping bearing with cross-arranged dynamic and static plates is used, and the relative surfaces of the dynamic and static plates are in contact to generate rotational damping in the viscous liquid.

[0007] The first solution uses a damping rod to provide a reaction force to counteract wind pressure. However, the direction of the wind pressure is different, and the direction of force on the damping rod is also different. The efficiency of the damping rod is highest only in the axial direction. The efficiency of the damping rod in other directions is affected. In addition, the assembly clearance of mechanical components and the rigid deformation capacity of the system itself will cause the damper to fail to respond to wind loads in a timely manner. The mechanical clearance will cause fatigue damage to related parts under the action of wind loads. The second solution uses pins to generate damping. However, a single small pin is small in size and has a small contact area. A large number of pins are required to achieve the designed performance. Too many pins result in high drilling costs and assembly time costs, and the entire product cost is too high. The third solution uses dynamic and static plates to generate damping, but the dynamic and static plates will have a certain gap movement, and the spacing is not a constant value, resulting in the damping value not being a stable value, and the damping force is not stable.

[0045] The following is a description of a damping bearing with a clamping function and a photovoltaic assembly of the utility model in combination with a schematic diagram, wherein a preferred embodiment of the utility model is shown. It should be understood that those skilled in the art can modify the utility model described herein and still achieve the advantageous effects of the utility model. Therefore, the following description should be understood as being widely known to those skilled in the art and not as a limitation to the utility model.

[0046] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0047] Embodiment 1

[0048] This embodiment provides a damping bearing with a clamping function, including: a bearing seat 4, a left end cover 2, a right end cover 3 and an outer ring damping plate 1.

[0049] For details, please refer to Figure 1-Figure 10 The left end cover 2 and the right end cover 3 are respectively sleeved on both sides of the bearing seat 4; the outer ring damping plate 1 is fixed between the left end cover 2 and the right end cover 3, and there is a flow gap between the outer ring damping plate 1 and the left end cover 2 and the right end cover 3, and the flow gap is filled with working fluid.

[0050] In this embodiment, the outer ring damping plate 1 can rotate circumferentially relative to the left and right end covers, so that the working fluid generates viscous resistance in the flow gap to form a damping effect. The resistance depends on the contact area, relative movement speed, contact gap and viscosity coefficient of the damping plate. The relative position of the left and right end covers and the outer ring damping plate 1 will not change with the change of external force, so that the contact area, damping contact gap and viscosity coefficient of the damping plate are all constant values. The damping force only changes with the speed of the outer ring damping plate 1 rotating circumferentially relative to the left and right end covers, thereby improving the controllability of the damping force.

[0051] In this embodiment, a plurality of protrusions and grooves are provided on one surface of the left end cover 2 and the right end cover 3, and a plurality of protrusions and grooves are also provided on two opposite surfaces of the outer ring damping plate 1. When the outer ring damping plate 1 is inserted into the interior of the left and right end covers 3 and fixed to the left and right end covers 2 and 3, a one-to-one matching relationship is formed between the protrusions and the grooves, and a flow gap is formed between the plurality of protrusions and the grooves for circulating and accommodating the working fluid. When relative movement occurs between the outer ring damping plate 1 and the left and right end covers 3, the working fluid can flow in the flow gap, thereby generating viscous resistance and forming a damping effect.

[0052] For a specific example, see Figure 4-Figure 5 The outer ring damping plate 1 includes a base, and a first annular mating flange 200 and a second annular mating flange 300 are respectively provided on two opposite surfaces of the base around the outer circumference of the base.

[0053] A first mating boss 400 and a second mating boss 500 are respectively disposed on two opposite surfaces of the base, and a third mating boss 600 and a fourth mating boss 700 are respectively disposed inside the first mating boss 400 and the second mating boss 500 .

[0054] A first mating groove 800 and a second mating groove 900 are formed between the first annular mating flange 200 and the first mating boss 400 , and between the second annular mating flange 300 and the second mating boss 500 , respectively.

[0055] The side surfaces of the first annular mating flange 200 and the second annular mating flange 300 close to the working fluid injection hole 410 are tilted, which is beneficial to slowing down the flow rate of the working fluid, thereby further improving the damping force and generating a greater damping torque.

[0056] The first annular mating flange 200 and the second annular mating flange 300, the first mating boss 400 and the second mating boss 500, the third mating boss 600 and the fourth mating boss 700 are all symmetrically arranged about the base of the outer ring damping plate 1 to form an outer ring damping plate 1 with a symmetrical structure. The structures of the left and right end covers 3 are the same, so that the damping forces formed between the outer ring damping plate 1 and the left end cover 2, and between the outer ring damping plate 1 and the right end cover 3 are the same.

[0057] In another specific example, see Figure 6 , is a structural schematic diagram of the left and right end covers, a third annular mating flange 230 and a fourth annular mating flange 330 as well as a fifth annular mating flange 240 and a sixth annular mating flange 340 are respectively provided on one surface of the left end cover 2 and the right end cover 3; a third mating groove 260 is formed between the third annular mating flange 230 and the fifth annular mating flange 240, and a fourth mating groove 360 ​​is formed between the fourth annular mating flange 330 and the sixth annular mating flange 340.

[0058] A fifth mating boss 250 and a sixth mating boss 350 are respectively disposed on one side close to the fifth annular mating flange 240 and the sixth annular mating flange 340 .

[0059] Please refer to Figure 2 and Figure 3 In this embodiment, the outer surface of the bearing seat 4 is further provided with a working fluid injection hole 410, and a large flow gap 4-2 is provided between the base of the outer ring damping plate 1 and the working fluid injection hole 410. After the working fluid is injected from the working fluid injection hole 410 into the flow gap 420 between the base of the outer ring damping plate 1 and the working fluid injection hole 410, it is diverted and flows into the space between one surface 1001 of the base and the third annular mating flange 230, the space between the first annular mating flange 200 and the third mating groove 260, and the space between the fifth ring The working fluid flows into the space between the annular mating flange 240 and the first mating groove 800, part of the table surface of the first mating boss 400 and part of the table surface of the fifth mating boss 250; and also flows into the space between the other surface 1002 of the base and the fourth annular mating flange 330, between the second annular mating flange 300 and the fourth mating groove 360, between the sixth annular mating flange 340 and the second mating groove 900, part of the table surface of the second mating boss 500 and part of the table surface of the sixth mating boss 350. The working fluid flows in the above-mentioned flow gap, and multiple annular mating flanges and the ring produce a damping effect.

[0060] In this embodiment, the size of the flow gap formed between the mating groove and the mating flange, and between the mating groove and the mating boss can be set to be the same to simplify the design and processing steps; the specific size setting of the flow gap needs to take into account appropriate flow resistance and higher bearing precision; the flow gap and the connecting parts between the flow gaps can adopt smooth surfaces to reduce friction resistance and improve flow efficiency.

[0061] In a specific example, the working fluid injection hole 410 is a threaded hole, which can not only be used for oil injection and installation of a retaining valve, but also can maintain the pressure balance between the inner cavity and the outer cavity of the bearing through the threaded hole.

[0062] In summary, the multiple closed flow gaps formed between the above-mentioned matching grooves and matching bosses help to disperse the working fluid and achieve uniform pressure distribution, and the multiple grooves and bosses cooperate with each other to increase the amount of damping working fluid between the gaps and thus increase the damping force.

[0063] For further information, please refer to Figure 6 and Figure 7 The inner surfaces of the fifth mating boss 250 in the left end cover 2 and the sixth mating boss 350 in the right end cover 3 are also provided with a copper sleeve mounting groove 210, and the first copper sleeve 5 and the second copper sleeve 6 are respectively sleeved in the copper sleeve mounting groove 210, and are respectively arranged between the fifth mating boss 250, the first mating boss 400 and the third mating boss 600, and between the sixth mating boss 350, the second mating boss 500 and the fourth mating boss 700.

[0064] Please refer to continue reference Figure 6 and Figure 7 The inner surfaces of the fifth mating boss 250 in the left end cover 2 and the sixth mating boss 350 in the right end cover 3 are also provided with a sealing ring mounting groove 220, and the first sealing ring 7 and the second sealing ring 8 are respectively sleeved in the sealing ring mounting groove 220, and are respectively arranged between the fifth mating boss 250, the first mating boss 400 and the third mating boss 600, and between the sixth mating boss 350, the second mating boss 500 and the fourth mating boss 700.

[0065] Among them, the copper sleeve and the sealing ring both seal the working fluid, prevent leakage of the working fluid, and maintain the pressure balance inside and outside the damping bearing.

[0066] In addition, the third sealing ring 11 and the fourth sealing ring 12 are also included. The third sealing ring 11 and the fourth sealing ring 12 are respectively sleeved on the annular grooves on the inner surface of the bearing seat 4. The third sealing ring 11 and the fourth sealing ring 12 are respectively located on both sides of the outer ring damping plate 1.

[0067] Furthermore, this embodiment also includes a clamping device consisting of an extrusion sleeve 9 and a clamping sleeve 10.

[0068] For details, please refer to Figure 2 The extrusion sleeve 9 is set between the clamping sleeve 10 and the outer ring damping plate 1, and is fixed to the right end cover 3. There are evenly arranged operation holes along the outer circumferential surface of the extrusion sleeve 9, and the wrench can be inserted into the operation holes. Please refer to Figure 8 There is a threaded fit between the extrusion sleeve 9 and the outer ring damping plate 1. The thread is turned by a wrench to move the extrusion sleeve 9 toward the center of the bearing seat 4; please refer to Fig. 9 The extrusion sleeve 9 and the jacket 10 are tapered (the two are tapered on the inclined surface 910), and the two work together to hold and center the left end of the photovoltaic group tracking bracket main beam. At the same time, when the jacket 10 is squeezed and moves toward the center of the bearing seat 4, the outer ring damping sheet 1 and the jacket 10 are also tapered (the two are tapered on the inclined surface 920), so the gap between the damping bearing and the right end of the photovoltaic group tracking bracket main beam is eliminated, so that the photovoltaic group tracking bracket main beam is clamped.

[0069] The clamping device mentioned above eliminates the structural shock load caused by the gap, which is beneficial to improving the life of the bearing and putting the bearing in a safe working environment.

[0070] In summary, the damping bearing with clamping function provided in this embodiment can not only form a constant damping flow gap between the left and right end covers and the outer ring damping plate 1, but also generate a stable damping torque in a confined space when the outer ring damping plate 1 moves relative to the left and right end covers. A clamping device is designed in the damping bearing, and the outer ring damping plate 1 and the main beam of the photovoltaic tracking bracket are clamped without gap through the cooperation of the extrusion sleeve 9 and the clamping sleeve 10, thereby eliminating the impact load caused by the gap and further improving the stability of the damping torque. The above-mentioned damping bearing has a simple structure and can be widely used in scenarios such as photovoltaic tracking brackets that require damping and clamping functions.

[0071] Embodiment 2

[0072] This embodiment provides a photovoltaic assembly, including: a photovoltaic tracking bracket and the damping bearing with clamping function provided in the first embodiment, and the damping bearing in the first embodiment is clamped on the main beam of the photovoltaic tracking bracket by the clamping device provided in the first embodiment.

[0073] When the photovoltaic bracket is operating under normal conditions, the speed is very low, and the damping bearing generates a very low damping torque. The motor overcomes this damping torque and operates normally. When strong winds come, the tracking bracket shuts down for protection, and the components under the long bracket are affected by the strong wind, causing the main square tube to shake and sway. When the main beam swings to the left, the outer ring damping plate 1 moves to the left relative to the right end cover 3. At this time, the right end cover 3 is relatively fixed, and the outer ring damping plate 1 moves to the left relative to the right end cover 3; when the main beam swings to the right, the outer ring damping plate 1 moves to the right relative to the left end cover 2. At this time, the left end cover 2 is relatively fixed, and the outer ring damping plate 1 moves to the right relative to the left end cover 2. At high speeds, the damping bearing will generate a large damping torque to prevent the photovoltaic components from swaying with the wind. When the wind speed gradually decreases, the damping force will gradually decrease.

[0074] This embodiment integrates the damping structure into the bearing, which directly acts on the main beam of the photovoltaic tracking bracket, thereby improving the response speed. The constant damping torque can adapt to different wind conditions and improve efficiency.

[0075] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
