Description

Technical Field

[0001] This utility model relates to the field of power supply equipment technology, specifically to an integrated wind, solar, diesel, and energy storage power supply device. Background Technology

[0002] The integrated wind-solar-diesel-storage device includes a wind power generation system, a photovoltaic power generation system, a diesel power generation system, and a power supply system. Each power generation system generates electrical energy and stores it in the power supply system, which then supplies power to electrical facilities through the energy storage system.

[0003] Power systems typically use energy storage cabinets, which contain battery modules and a large number of electrical components. When the cabinet vibrates, it may cause internal solder joints to crack and wiring to loosen. Therefore, when the integrated wind, solar, diesel and energy storage unit operates in a strong vibration environment (for example, when supplying power to an oil pump, which is a heavy-duty reciprocating machine that generates continuous vibration during operation), appropriate vibration reduction measures are required.

[0004] Existing patent (CN222775858U) describes an energy storage cabinet with vibration damping function. By hinged the bottom of the energy storage cabinet to the base through a damper, and then placing multiple sets of springs between the base and the energy storage cabinet, the springs are distributed at the bottom and around the energy storage cabinet to resist vibrations in multiple directions. Although the above solution can play a certain role in vibration damping, the springs in the above solution can only resist forces parallel to the X, Y, and Z axes. However, when the pumping unit is working, oblique or even torsional forces may be generated, which will cause each spring to be subjected to different forces, making it difficult to coordinate. Moreover, the continuous shaking of the springs may cause resonance, which will increase the shaking and further increase the burden on the damper. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an integrated power supply device for wind, solar, diesel and storage. Through the combination of steel wire rope and counterweight plate, it achieves vibration isolation effect in all directions, reduces the shaking of the cabinet, and can play a better anti-vibration effect on the cabinet in the oil pumping environment.

[0006] The technical solution adopted in this utility model is as follows: A wind, solar, diesel, and storage integrated power supply device includes a cabinet and a base fixed on the ground. A counterweight plate is fixedly connected to the bottom of the cabinet. Vibration isolation components are respectively provided at the four corners of the counterweight plate. Each vibration isolation component includes an upper connecting plate installed at the bottom of the counterweight plate and a lower connecting plate installed at the top of the base. Spiral steel wire ropes are interlaced between the upper connecting plate and the lower connecting plate.

[0007] Working principle: Since the wire rope is made of multiple strands of rope core wound together, when subjected to external vibration, the multiple strands of rope core will convert the vibration into heat energy and dissipate it through bending, stretching, and frictional slippage between the rope cores. In addition, because the wire rope is helical, it can resist vibration in multiple directions. The stiffness of the wire rope is non-linear. As the vibration increases, the inside of the wire rope is compressed, and the stiffness also increases, making it less likely for multiple vibration isolation components to resonate.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: By installing spiral steel wire ropes at each of the four corners, vibration isolation is achieved in all directions. Furthermore, by adding counterweight plates, the overall center of gravity of the cabinet is lowered, reducing the swaying of the cabinet. In an oil extraction environment, this provides better vibration protection for the cabinet.

[0009] In a preferred embodiment of this utility model, each vibration isolation component forms a triangle with the two sides of the counterweight plate.

[0010] Beneficial effects: By setting the damping component diagonally in four directions, the force in each direction is made more uniform as much as possible, resulting in better vibration isolation.

[0011] In a preferred embodiment of this utility model, the mass ratio of the counterweight plate to the cabinet body is 3:1.

[0012] Beneficial effects: By setting the proportions as described above, the overall center of gravity is lowered as much as possible, ensuring that the weight of the counterweight plate and the cabinet does not exceed the bearing limit of the vibration isolation components, while also ensuring that the vibration isolation components are in the optimal working range.

[0013] In a preferred embodiment of the present invention, a frame is fixedly connected to the base, and a shielding part is provided on the upper inner side of the frame, which shields the gap between the frame and the counterweight plate.

[0014] Beneficial effects: In the working environment of an oil pumping unit, the air is prone to contain oil, dust, and corrosive gases. If oil and dust adhere to the gaps between the wire ropes, and corrosive gases may cause corrosion on the surface of the wire ropes, both of which will affect the slippage and friction of the rope core, thus affecting the vibration isolation effect. By setting up a shield, the base, frame, shield, and counterweight plate form a relatively sealed space, reducing the impact of air on the vibration isolation components.

[0015] In a preferred embodiment of this utility model, the upper part of the side wall of the counterweight plate is provided with stepped grooves, and the blocking part can slide relative to each other in the stepped grooves, so that the top surface of the frame and the top plate of the counterweight plate are on the same plane.

[0016] Beneficial effect: The above settings make the top surface of the frame and the top plate of the counterweight plate the same plane, which makes it easier to open the cabinet door.

[0017] In a preferred embodiment of the present invention, the shielding part includes an elastic filler, which is a rectangular frame. The cross-section of a single side of the rectangular frame is an inverted L-shape, and it can be placed on a stepped groove.

[0018] Beneficial effects: The inverted L-shaped rectangular frame can be inserted into the stepped groove by its own elasticity and tightened between the frame and the counterweight plate, which can isolate the external air. It is also easy to disassemble and assemble and can adapt to deformation during vibration.

[0019] In a preferred embodiment of this utility model, the top surface of the elastic filler is provided with a waterproof film.

[0020] Beneficial effects: The waterproof membrane effectively prevents liquids from seeping into the base through the elastic filler.

[0021] In a preferred embodiment of this utility model, the stepped groove is provided with a plurality of stepped holes vertically, and the upper connecting plate is provided with a plurality of threaded holes corresponding to the stepped holes. Bolts can be installed through the corresponding stepped holes and threaded holes to fix the upper connecting plate and the counterweight plate.

[0022] Beneficial effects: With the above settings, after the cabinet and counterweight plate are installed, the whole unit can be placed on the vibration isolation component by hoisting. After alignment, bolts can be installed from the outside to fix the upper connecting plate and counterweight plate, making disassembly and assembly more convenient. Attached Figure Description

[0025] Typical embodiments embodying the features and advantages of this utility model will be specifically described in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0026] In the description of this application, the terms "first", "second", etc. are used only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the structure referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0027] See Figure 1 As shown, the integrated wind, solar, diesel and storage power supply device disclosed in this embodiment includes a cabinet 1, a counterweight plate 2, a base 3, and a vibration isolation component 4.

[0028] The base 3 and the counterweight plate 2 are formed by concrete casting. The base 3 is cast directly on the ground. After curing, a waterproof coating is applied. In other embodiments, a waterproof film can also be bonded to the surface.

[0029] The counterweight plate 2 has pre-embedded bolts during the pouring process. The cabinet 1 is fixed above the counterweight plate 2 by these bolts. The mass ratio of the counterweight plate 2 to the cabinet 1 is 3:1. After being fixed by the pre-embedded bolts, the counterweight plate 2 and the cabinet 1 are rigidly connected to form a whole, and the center of gravity is lowered as much as possible, thereby reducing swaying.

[0030] Among them, see Figure 2 As shown, the vibration isolation components 4 are located at the four corners of the counterweight plate 2, and each vibration isolation component 4 forms a triangle with the two sides of the corner of the counterweight plate 2. By setting the vibration damping components obliquely in four directions, the force in each direction is made more uniform as much as possible, and the vibration isolation effect is better.

[0031] Among them, see Figure 4 As shown, each vibration isolation component 4 includes an upper connecting plate 41 installed at the bottom of the counterweight plate 2 and a lower connecting plate 42 installed at the top of the base 3. The upper connecting plate 41 and the lower connecting plate 42 are interlaced with spiral steel wire ropes 43, which are made of multiple strands of rope core wound together. Through this structure, vibrations in multiple directions can be resisted and resonance is not easy to occur.

[0032] Among them, see Figure 3As shown, the upper side wall of the counterweight plate 2 is provided with stepped grooves 21, and multiple stepped holes 22 are vertically provided on the stepped grooves 21. The upper connecting plate 41 is provided with multiple threaded holes corresponding to the stepped holes 22. Bolts can be installed through the corresponding stepped holes 22 and threaded holes to fix the upper connecting plate 41 and the counterweight plate 2. By hoisting, the cabinet 1 is first placed on the counterweight plate 2 and fixed with pre-embedded bolts. Then, the whole unit can be hoisted onto the vibration isolation component 4. After alignment, bolts can be installed from the outside to fix the upper connecting plate 41 and the counterweight plate 2. The assembly and disassembly are relatively convenient.

[0033] Among them, see Figure 3 As shown, a frame 31 is provided on the base 3. Both the frame 31 and the base 3 are cast in one piece. A shielding part 32 is provided on the upper inner side of the frame 31. The shielding part 32 blocks the gap between the frame 31 and the counterweight plate 2. The shielding part 32 can slide relative to each other in the stepped groove 21, so that the top surface of the frame 31 and the top plate of the counterweight plate 2 are on the same plane, which facilitates the opening of the cabinet door of the cabinet 1.

[0034] Among them, see Figure 4 As shown, the shielding part 32 includes an elastic filler, which is a rectangular frame made of rubber material (this part does not need to resist vibration, but only adapts to deformation, so foamed silicone or memory foam can also be used). The cross-section of a single side of the rectangular frame is an inverted L-shape, which can be placed on the stepped groove 21. The inverted L-shaped rectangular frame can be inserted into the stepped groove 21 by its own elasticity and tightened between the frame 31 and the counterweight plate 2, which can isolate the external air. It is also easy to disassemble and assemble and can adapt to deformation during vibration.

[0035] The top surface of the elastic filler is provided with a waterproof membrane, which can effectively prevent liquid from seeping into the base 3 through the elastic filler.

[0036] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
