Description

Technical Field

[0001] This utility model belongs to the field of hydrogen energy compressor assembly technology, and specifically provides a pre-embedded vibration damping connection structure for hydrogen energy compressors. Background Technology

[0002] Hydrogen compressors play a crucial role in the hydrogen energy industry chain, and their performance directly determines the efficiency of hydrogen storage, transportation, and application. However, during operation, hydrogen compressors often generate vibrations, which not only shorten the equipment's lifespan and reduce its reliability but may also pose a threat to the surrounding environment and personnel safety.

[0003] In existing technical solutions, hydrogen compressors are typically fixed to the foundation of the ground using bolts and nuts. This installation method lacks vibration damping design and cannot effectively mitigate the vibrations generated during compressor operation. Furthermore, the use of bolts and nuts makes it difficult to disassemble the hydrogen compressor's support legs, which is detrimental to the compressor's maintenance and repair at the factory. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a pre-embedded vibration damping connection structure for a hydrogen energy compressor, including a rubber vibration damper, a mounting cylinder, a locking mechanism, and an extrusion assembly. The rubber vibration damper is installed in the foundation and is fixedly connected to the bottom end of the mounting cylinder. Several locking mechanisms are arranged in a ring array around the mounting cylinder. The mounting cylinder has a top-opening insertion hole in the middle along the length direction. The insertion hole is connected to the support leg of the hydrogen energy compressor. Several locking holes are opened around the support leg. The extrusion assembly is slidably sleeved onto the outer wall of the mounting cylinder.

[0005] Furthermore, a first spring is provided between the extrusion assembly and the mounting cylinder, and the extrusion assembly is connected to several locking mechanisms;

[0006] The extrusion assembly is connected to a pressure plate.

[0007] Furthermore, the rubber vibration damper is pre-embedded in the foundation, and when the concrete is poured, the upper surface of the rubber vibration damper is kept level with the upper surface of the foundation concrete.

[0008] Each of the four pre-embedded vibration damping mounting structures is connected to a pressure plate.

[0009] Furthermore, a panel is fixedly installed inside the rubber shock absorber, and a through hole is provided in the middle of the panel.

[0010] Furthermore, a threaded post is fixedly installed at the bottom end of the mounting cylinder, the threaded post passes through the through hole, and a nut is threaded onto the threaded post.

[0011] Furthermore, a gasket is provided on the bottom end face of the mounting cylinder.

[0012] Furthermore, the locking mechanism includes a second spring and a locking block. The outer wall and inner wall of the mounting cylinder are respectively provided with a concave hole and a guide hole. The concave hole and the guide hole are aligned and communicate with each other. The locking block is connected to the guide hole with a clearance fit. The second spring is sleeved on the locking block and is located in the concave hole.

[0013] One end of the second spring is fixedly connected to the locking block, and the other end of the second spring is fixedly connected to the wall of the concave hole;

[0014] The extrusion assembly includes a sliding sleeve and a bottom sleeve base. The bottom sleeve base is fixedly connected to the bottom end of the sliding sleeve, and the top end of the sliding sleeve is connected to the outer wall of the mounting cylinder with a clearance fit.

[0015] Furthermore, the inner wall of the bottom sleeve is provided with a number of inclined grooves arranged in a circular array, and the distance between the inclined grooves and the side wall of the mounting cylinder gradually decreases from top to bottom; one end of the locking block is provided with an inclined end, and the inclined groove is slidably connected to the inclined end of the locking block.

[0016] A baffle is fixedly installed on the outer wall of the mounting cylinder. A first spring is sleeved on the mounting cylinder and is located above the baffle. The top and bottom ends of the first spring are in contact with the inner wall of the top of the sliding sleeve and the top surface of the baffle, respectively.

[0017] Furthermore, the rubber damper is a rubber block, and the rubber block is a composite rubber made of ethylene propylene diene monomer rubber and fluororubber.

[0018] The beneficial effects of using this utility model are:

[0019] This design can be adapted to the support legs of different models of hydrogen compressors. By using rubber vibration dampers pre-embedded in the foundation to connect with the support legs of the hydrogen compressor, when subjected to the load vibration of the hydrogen compressor, the deformation of the rubber vibration dampers absorbs the impact generated by the vibration of the hydrogen compressor, thereby achieving the vibration reduction effect.

[0020] The mounting cylinder provides insertion positions for the hydrogen compressor's feet through the insertion holes, and the inserted hydrogen compressor feet are locked by a locking mechanism. The synchronous control of multiple locking mechanisms is achieved through the compression assembly and the pressure plate, which ensures both the stability of this design when installed on the hydrogen compressor feet and the convenience of the disassembly process.

[0040] The present invention will now be described in detail with reference to the accompanying drawings.

[0041] Reference Figures 1-4 An embedded vibration damping connection structure for a hydrogen compressor includes a rubber vibration damper 1, a mounting cylinder 2, a locking mechanism, and an extrusion assembly. The rubber vibration damper 1 is installed in the foundation 9 and is fixedly connected to the bottom end of the mounting cylinder 2. Several locking mechanisms are arranged in a ring array around the mounting cylinder 2. The mounting cylinder 2 has a top-opening insertion hole in the middle along the length direction. The insertion hole is connected to the support leg 5 of the hydrogen compressor. Several locking holes 501 are opened around the support leg 5. The extrusion assembly sliding sleeve 3 is connected to the outer cylinder wall of the mounting cylinder 2.

[0042] A first spring 6 is provided between the extrusion assembly and the mounting cylinder 2. The extrusion assembly is connected to several locking mechanisms so that the single extrusion assembly can synchronously drive the several locking mechanisms to lock or unlock.

[0043] The extrusion assembly is connected to a pressure plate 10.

[0044] The rubber vibration damper 1 is embedded in the foundation 9. When the concrete is poured, the upper surface of the rubber vibration damper 1 is kept level with the upper surface of the foundation concrete.

[0045] Rubber damper 1 is a rubber block.

[0046] Preferably, the rubber vibration damper 1 is a composite material made of EPDM (ethylene propylene diene monomer rubber), fluororubber, and other auxiliary additives, which has excellent anti-aging and corrosion resistance. EPDM material can withstand high temperature and high pressure, while fluororubber increases resistance to chemicals. Simultaneously, carbon fiber or glass fiber is added to the rubber to enhance the strength and toughness of the vibration damper.

[0047] Reference Figures 1-3 As shown, the rubber vibration damper 1 has several evenly distributed holes 101. The holes 101 form a dense, porous structure.

[0048] Each of the four support legs 5 of the hydrogen compressor is individually connected to the foundation 9 via a pre-embedded vibration damping installation structure. The vibration of the hydrogen compressor is absorbed by the deformation of the rubber vibration dampers 1 in the four pre-embedded vibration damping installation structures.

[0049] Reference Figure 4 As shown, the extrusion components of the four pre-embedded vibration damping installation structures are all connected to a pressure plate 10.

[0050] Reference Figures 1-3 As shown, a panel 102 is fixedly installed inside the rubber shock absorber 1, and a through hole is provided in the middle of the panel 102.

[0051] A threaded post 201 is fixedly installed at the bottom of the mounting cylinder 2. The threaded post 201 passes through the through hole, and a nut 202 is threaded onto the threaded post 201.

[0052] A gasket 203 is provided on the bottom end face of the mounting cylinder 2;

[0053] The mounting cylinder 2 is fixed to the insert plate 102 inside the rubber damper 1 by the threaded post 201 and the nut 202. The insert plate 102 is made of steel plate.

[0054] Reference Figures 1-4As shown, as a specific technical solution, the locking mechanism includes a second spring 7 and a locking block 8. The outer wall and inner wall of the mounting cylinder 2 are respectively provided with a recessed hole 205 and a guide hole 206. The recessed hole 205 and the guide hole 206 are aligned and communicate with each other. The locking block 8 is connected to the guide hole 206 with a clearance fit. The second spring 7 is sleeved on the locking block 8 and is located in the recessed hole 205.

[0055] One end of the second spring 7 is fixedly connected to the locking block 8, and the other end of the second spring 7 is fixedly connected to the wall of the recess 205.

[0056] The extrusion assembly includes a sliding sleeve 3 and a bottom sleeve 4. The bottom sleeve 4 is fixedly connected to the bottom end of the sliding sleeve 3, and the top end of the sliding sleeve 3 is connected to the outer wall of the mounting cylinder 2 with a clearance fit.

[0057] The inner wall of the bottom sleeve 4 is provided with several inclined grooves 401 arranged in a ring array, and the distance between the inclined grooves 401 and the side wall of the mounting cylinder 2 gradually decreases from top to bottom; one end of the locking block 8 is provided with an inclined end, and the inclined grooves 401 are slidably connected to the inclined end of the locking block 8.

[0058] A baffle 204 is fixedly installed on the outer wall of the mounting cylinder 2. A first spring 6 is sleeved on the mounting cylinder 2 and is located above the baffle 204. The top and bottom ends of the first spring 6 are in contact with the top inner wall of the sliding sleeve 3 and the top surface of the baffle 204, respectively.

[0059] Reference Figures 1-4 At this time, the support leg 5 of the hydrogen compressor is in a fixed state, and the locking mechanism locks the support leg 5. The first spring 6 is in a compressed state, providing upper pressure to the extrusion assembly, so that the extrusion assembly extrudes the inclined end of the locking block 8 through the inclined groove 401, so that the second spring 7 is in a compressed state, and the locking block 8 is inserted into the locking block 8.

[0060] During disassembly, heavy objects, such as external stones, are placed on the pressure plate 10. The pressure plate 10 is subjected to downward pressure, causing the compression components at the four support legs 5 (i.e., the sliding sleeve 3 and the bottom sleeve 4) to move downward together (simultaneously compressing the first spring 6, increasing its compression). The inclined groove 401 on it moves downward about the locking block 8, and the inclined end of the locking block 8 is always located in the inclined groove 401 due to the compression force of the second spring 7. That is, the inclined end of the locking block 8 slides in the inclined groove 401, and the distance between the inclined groove 401 and the mounting cylinder 2 gradually decreases from top to bottom. Figure 3 As shown; the inclined end of the locking block 8 is located at the top of the inclined groove 401, and the locking block 8 is at the maximum distance between the inclined groove 401 and the mounting cylinder 2. The locking block 8 is pulled out from the locking hole 501, the support leg 5 loses its lock, and then the hydrogen energy compressor is lifted to disengage the support leg 5 from the mounting cylinder 2, thus completing the disassembly.

[0061] After disassembly, maintenance can be performed. Upon reinstallation, insert the support leg 5 into the insertion hole of the mounting cylinder 2. After insertion, align the locking block 8 with the locking hole 501. Then, remove the weight from the pressure plate 10. The compression force of the first spring 6 pushes the sliding sleeve 3 and the bottom sleeve 4 upwards together, pressing the inclined end of the locking block 8 through the inclined groove 401, causing the locking block 8 to insert into the locking hole 501. Simultaneously, the second spring 7 is compressed until it returns to the reference position. Figure 3 The state shown.

[0062] In summary, locking and unlocking the support leg 5 only requires removing or placing heavy objects on the pressure plate 10, which makes the assembly and disassembly of the support leg 5 convenient.

[0063] The above content is only a preferred embodiment of this utility model. For those skilled in the art, many changes can be made in the specific implementation and application scope based on the concept of this utility model. As long as these changes do not depart from the concept of this utility model, they all fall within the protection scope of this utility model.
