Description

Technical Field

[0002] This invention relates to the field of integrated energy storage and cryogenic refrigeration technology, specifically to an integrated energy storage and cryogenic refrigeration system. Background Technology

[0003] Most small and medium-sized wind turbines currently use a direct-drive structure, characterized by a direct connection between the blade flange and the engine shaft, with the blade speed matching the motor speed. Wind turbines generally consist of components such as a rotor, generator, deflector, tower, speed limiting safety mechanism, and energy storage device. Therefore, the demand for low-temperature environments is constantly increasing. Traditional refrigeration systems mainly consist of a compressor, condenser, throttling device, and evaporator connected in sequence to form a circulation pipeline, used to form an integrated low-temperature refrigeration unit for operation.

[0004] Traditional integrated energy storage and cryogenic refrigeration units mostly use recovery equipment, such as hydrogen recovery, which requires the installation of many pipelines to transport the recovered medium. In order to protect the assembly box, the assembly box is usually installed at a certain distance from the ground. However, it is inconvenient to operate during maintenance and repair, and the assembly box needs to be lowered. Because of the integrated nature of the system, there are many pipelines, and it is inconvenient for the pipes inside the assembly box to be lowered with the assembly box. Therefore, it is necessary to temporarily disconnect the pipelines, and there is no good pipeline sealing method, which makes the recovered medium prone to leakage.

[0005] To address the aforementioned issues, this application proposes an integrated energy storage and cryogenic refrigeration unit. Summary of the Invention

[0008] Furthermore, the limiting component includes a limiting rod and a spring A. The limiting rod is fixedly connected to the top of the base. The limiting rod passes through the surface of the assembly box. The outer side of the limiting rod is slidably connected to the assembly box. The spring A is fixedly connected between the top of the base and the assembly box. The spring A is disposed at the circumferential position of the limiting rod.

[0009] Furthermore, the limiting component includes a latch and a spring B. A spring groove is provided on the inner side of the base. The front end of the spring groove is connected to the rear end of the inner sidewall of the latch. The spring B is slidably connected to the inner sidewall of the spring groove. The latch is fixedly connected between the rear end face of the spring B and the inner sidewall of the spring groove.

[0010] Furthermore, the pedal is L-shaped, the pedal's movement trajectory is straight, the slot is located on the pedal's movement trajectory, the latch is located on the pedal's movement trajectory, the latch is wedge-shaped, and the outer side of the pedal is slidably connected to the latch.

[0012] Furthermore, the top end of the fixed tube B is provided with a screw end, and the bottom outer side of the fixed tube C is rotatably connected with a female sleeve, and the screw end of the fixed tube B is threadedly connected to the female sleeve of the fixed tube C.

[0013] Furthermore, the distance between the bottom end of the fixed tube B and the top end of the fixed tube A is 0.5 times the length of the flexible tube.

[0014] Furthermore, the automatic pipe closing assembly includes a sliding sleeve, a sliding rod, a stop block, a mounting rod, a rotating sleeve, a support rod, a pressure roller, and a spring C. The sliding sleeve is fixedly connected to the top of the bracket. A sliding groove is formed on the inner side of the sliding sleeve. Two sliding rods are slidably connected to the inner side wall of the sliding groove. The two sliding rods are centrally symmetrically arranged and slidably connected to each other.

[0017] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes a separation and connection mechanism, a pipe closure mechanism, and a leak-proof mechanism. The recycling equipment is housed within an assembly box. When maintenance is required, the female connector is rotated on the fixed pipe C to separate it from the threaded end of the hose. Stepping on the pedal causes the assembly box to slide downwards on the main body of the equipment. The two mounting rods, limited by the limiting rail, move closer together, causing the sliding rod to slide within the sliding sleeve. This, in turn, brings the two sets of pressure rollers on the left and right closer together, resulting in the top two pressure rollers and the bottom two pressure rollers clamping and sealing the hose, achieving automatic sealing of the hose. This sealing occurs synchronously as the assembly box moves downwards, preventing leakage of the recycled medium. The operation is simple. When maintenance is not required, the assembly box can be raised again for protective operation to prevent accidental collisions with other objects. Attached Figure Description

The specific connection methods of each part adopt conventional methods such as bolts, rivets, welding, and bonding that are mature in the prior art. The components used for circuit connection are all conventional models in the prior art.

[0021] Meanwhile, in order to clearly express the connection relationship and working principle between the components and highlight the key points, the accompanying drawings in the instruction manual are organized and drawn in the form of simplified diagrams. One simplified diagram can correspond to multiple materials and actual external structural shapes.

[0022] Please see Figures 1-8This invention provides a technical solution: an integrated energy storage and cryogenic refrigeration unit, comprising an integrated energy storage and cryogenic refrigeration device 1. The integrated energy storage and cryogenic refrigeration device 1 includes a main body 11, an assembly box 12, and a box cover 13. The assembly box 12 is slidably mounted on the left side of the main body 11, and the box cover 13 is provided on the assembly box 12. The right end of the box cover 13 is fixedly connected to the main body 11. The integrated energy storage and cryogenic refrigeration device 1 is equipped with a splitting and closing mechanism 2 for adjusting the height of the assembly box 12. The splitting and closing mechanism 2 is equipped with a pipe closing mechanism 3. The integrated energy storage and cryogenic refrigeration device 1 is equipped with a leak-proof mechanism 4 for closing the connecting assembly 32. The splitting and closing mechanism 2 includes a base 21, a limiting component 22, a pedal 23, and a limiting component 24. A bottom plate is fixedly connected to the left side of the bottom end of the main body 11. The base 21 has a limiting component 22 installed between it and the assembly box 12. A pedal 23 is fixedly connected to the bottom left side of the assembly box 12. A slot is provided on the inner side of the base 21, and a limiting component 24 is installed on the inner wall of the slot. The pipe closing mechanism 3 includes a recycling device 31, a connecting component 32, and a fixing pipe C33. The recycling device 31 is installed on the bottom inner side of the assembly box 12, the connecting component 32 is installed on the recycling device 31, and the fixing pipe C33 is installed on the connecting component 32. The leak prevention mechanism 4 includes a bracket 41, an automatic pipe closing component 42, and a limiting rail 43. The bracket 41 is fixedly connected to the top of the recycling device 31, and the automatic pipe closing component 42 is installed on the top of the bracket 41. Two limiting rails 43 are fixedly connected symmetrically to the bottom of the box cover 13. During use, because the integrated energy storage and cryogenic refrigeration equipment 1 is an integrated device, all its components are housed in a single enclosure, including the recycling equipment. The recycling device 31 is housed within the enclosure 12. When maintenance is required, the female connector is rotated on the fixed pipe C33 to separate it from the threaded end of the hose 322. The pedal 23 is then pressed, causing the enclosure 12 to slide downwards on the main body 11. The limiting rod 221 limits the movement of the enclosure 12, ensuring it moves vertically. The pedal 23 moves downwards until it reaches the slot on the base 21, where it pushes open the latch 241 and engages with the bottom of the inner wall of the slot. Then, the spring B242 pushes the latch 241 outwards, limiting the pedal 23. At this point, the enclosure 12 moves downwards. Separated from the cover 13, the assembly box 12 moves downward, causing the recycling device 31 to move downward. The recycling device 31 pulls the bracket 41 downward, and the bracket 41 pulls the sliding sleeve 421 downward. Limited by the limiting rail 43, the two mounting rods 424 slide downward on the outer side of the corresponding limiting rail 43. Limited by the limiting rail 43, the two mounting rods 424 move closer together. The mounting rods 424 drive the sliding rod 422 to slide within the sliding sleeve 421, thereby causing the left and right sets of pressure rollers 427 to move closer together. Because the rotating sleeve 425 can rotate on the mounting rods 424, the spring C428 pulls each set of two support rods 426, causing each set of two support rods 426 to move closer together. This causes the two top pressure rollers 427 and the two bottom pressure rollers 427 to clamp and seal the hose 322 respectively.The system automatically seals the hose 322, closing synchronously as the assembly box 12 moves downwards, preventing leakage of the recovered medium from the recovery device 31. Operation is simple. After maintenance, a reset is performed. When spring B242 retracts into its groove, spring A222 pushes the assembly box 12 to reset. At this time, the force of spring C428 pulling the two support rods 426 closer together causes each of the two pressure rollers 427 to push the hose 322. Because the two sets of pressure rollers 427 are aligned, the reaction force of the two sets of pressure rollers 427 pushing the hose 322 will cause the two mounting rods 424 to move away from each other. This movement of the mounting rods 424 causes the sliding rods 422 to separate from each other within the sliding sleeve 421. The stop block 423 prevents the sliding rods 422 from falling off. After reset, the female connector of the fixing pipe C33 is screwed onto the threaded end of the fixing pipe B323, thus completing the reset operation.

[0023] The limiting assembly 22 includes a limiting rod 221 and a spring A222. The limiting rod 221 is fixedly connected to the top of the base 21. The limiting rod 221 passes through the surface of the assembly box 12. The outer side of the limiting rod 221 is slidably connected to the assembly box 12. The spring A222 is fixedly connected between the top of the base 21 and the assembly box 12. The spring A222 is set in the circumferential position of the limiting rod 221. When the pedal 23 is stepped on, the pedal 23 drives the assembly box 12 to slide downward on the main body 11 of the equipment. The limiting rod 221 limits the assembly box 12, so that the assembly box 12 moves straight up and down. When the pedal 23 moves downward to the slot of the base 21, it pushes open the latch 241 and fits against the bottom end of the inner side wall of the slot. After maintenance, it is reset. When the spring B242 is pushed into the spring slot, the spring A222 pushes the assembly box 12 to reset the assembly box 12.

[0024] The limiting component 24 includes a latch 241 and a spring B242. A spring groove is provided on the inner side of the base 21. The front end of the spring groove is connected to the rear end of the inner side wall of the latch groove. The spring B242 is slidably connected to the inner side wall of the spring groove. The latch 241 is fixedly connected between the rear end face of the spring B242 and the inner side wall of the spring groove. When the pedal 23 moves downward to the latch groove of the base 21, it pushes the latch 241 open and fits against the bottom end of the inner side wall of the latch groove. Then, the spring B242 pushes the latch 241 to pop out and limit the pedal 23. After maintenance, it is reset. When the spring B242 is pushed into the spring groove, the spring A222 pushes the assembly box 12 to reset the assembly box 12.

[0025] The pedal 23 is L-shaped and moves in a straight line. The slot is located on the movement path of the pedal 23, and the latch 241 is located on the movement path of the pedal 23. The latch 241 is wedge-shaped and slides on the outer side of the pedal 23. When maintenance is required, the pedal 23 is stepped on, and the pedal 23 drives the assembly box 12 to slide downward on the main body 11. The limit rod 221 limits the assembly box 12, so that the assembly box 12 moves straight up and down. The pedal 23 moves downward to the slot of the base 21, pushes the latch 241 open, and fits against the bottom of the inner side wall of the slot. Then, the spring B242 pushes the latch 241 to pop out and limit the pedal 23.

[0026] The connecting assembly 32 includes a fixed tube A321, a flexible tube 322, and a fixed tube B323. The fixed tube A321 is installed at the top of the recycling device 31. The flexible tube 322 is fixedly connected to the top of the fixed tube A321. The other end of the flexible tube 322 is fixedly connected to the fixed tube B323. The outer side of the fixed tube B323 is fixedly connected to the cover 13. The distance between the bottom end of the fixed tube B323 and the top end of the fixed tube A321 is 0.5 times the length of the flexible tube 322. The flexible design of the flexible tube 322 is firstly to facilitate the clamping and sealing of the flexible tube 322 by the pressure rollers 427 on both sides of the flexible tube 322. Secondly, when the cover 13 is separated from the assembly box 12, the fixed tube A321 moves relative to the fixed tube B323, thereby causing the flexible tube 322 to gradually unfold.

[0027] The top of the fixed tube B323 is provided with a screw end, and the bottom outer side of the fixed tube C33 is rotatably connected to a female sleeve. The screw end of the fixed tube B323 is threadedly connected to the female sleeve of the fixed tube C33. When maintenance is required, the female sleeve is rotated on the fixed tube C33 to separate the female sleeve from the screw end of the hose 322. After maintenance, the tube is reset. After reset, the female sleeve of the fixed tube C33 is screwed onto the screw end of the fixed tube B323.

[0028] The automatic pipe closing assembly 42 includes a sliding sleeve 421, a sliding rod 422, a stop block 423, a mounting rod 424, a rotating sleeve 425, a support rod 426, a pressure roller 427, and a spring C428. The top of the bracket 41 is fixedly connected to the sliding sleeve 421. A groove is formed on the inner side of the sliding sleeve 421, and two sliding rods 422 are slidably connected to the inner wall of the groove. The two sliding rods 422 are centrally symmetrically arranged and slidably connected to each other. A mounting rod 424 is fixedly connected to the rear side of each sliding rod 422 at the end furthest from the mounting rod 424. A stop block 423 is fixedly connected to the end of each sliding rod 422 furthest from the mounting rod 424. Two rotating sleeves 425 are rotatably connected to the outer side of each mounting rod 424 via a rotating shaft. The two rotating sleeves 425 are arranged front to back. The outer side of the rotating sleeves 425 is fixedly connected to the stop block 423. A support rod 426 is fixedly connected to the hose 322. The other end of the support rod 426 is rotatably connected to a pressure roller 427 via a rotating shaft. A spring C428 is fixedly connected between each set of two pressure rollers 427. The two sets of pressure rollers 427 are symmetrically arranged on the left and right sides of the hose 322, and the two pressure rollers 427 in each set are arranged vertically on the same side of the hose 322. The outer side of the pressure roller 427 is slidably connected to the hose 322. Two limiting rails 43 are respectively located on the opposite side of the two mounting rods 424. The outer side of the mounting rods 424 is slidably connected to the limiting rails 43. Each limiting rail 43 is divided into three sections: upper, middle, and lower. The distance between the upper sections of the two limiting rails 43 is twice the distance between the two limiting rails 43. The middle section of the two limiting rails 43 is inclined. The assembly box 12 faces downwards. Separated from the cover 13, the assembly box 12 moves downward, causing the recycling device 31 to move downward. The recycling device 31 pulls the bracket 41 downward, and the bracket 41 pulls the sliding sleeve 421 downward. Limited by the limiting rail 43, the two mounting rods 424 slide downward outside the corresponding limiting rail 43. Limited by the limiting rail 43, the two mounting rods 424 move closer together. The mounting rods 424 drive the sliding rod 422 to slide within the sliding sleeve 421, thereby causing the left and right sets of pressure rollers 427 to move closer together. Because the rotating sleeve 425 can rotate on the mounting rods 424, the spring C428 pulls each set of two support rods 426, causing each set of two support rods 426 to move closer together. This causes the top two pressure rollers 427 and the bottom two pressure rollers 427 to respectively press the hose 32... 2. Clamping and sealing automatically seals the hose 322. The sealing occurs synchronously as the assembly box 12 moves downwards, preventing leakage of the recovered medium from the recycling equipment 31. Operation is simple. After maintenance, the hose is reset. When spring B242 retracts into its groove, spring A222 pushes the assembly box 12 to reset. At this time, the force of spring C428 pulling the two support rods 426 closer together causes each of the two pressure rollers 427 to push the hose 322. Because the two sets of pressure rollers 427 are aligned, the reaction force of the two sets of pressure rollers 427 pushing the hose 322 will cause the two mounting rods 424 to move away from each other. This movement of the mounting rods 424 causes the sliding rods 422 to separate from each other within the sliding sleeve 421. The stop block 423 prevents the sliding rods 422 from falling off.After resetting, screw the female connector of fixing tube C33 onto the threaded end of fixing tube B323.

[0029] Working principle: When this device is in use, because the integrated energy storage and cryogenic refrigeration equipment 1 is an integrated device, all its components are housed in one box, including the recycling equipment. The recycling equipment 31 is housed in the assembly box 12. When maintenance is required, the female connector is rotated on the fixed pipe C33 to separate the female connector from the threaded end of the hose 322. The pedal 23 is then stepped on, causing the assembly box 12 to slide downwards on the main body 11. The limit rod 221 limits the assembly box 12, allowing it to move vertically. The pedal 23 moves downwards until it reaches the slot of the base 21, where it pushes open the latch 241 and engages with the bottom of the inner wall of the slot. Then, the spring B242 pushes the latch 241 outwards, limiting the pedal 23. At this point, the assembly box 12 separates downwards from the box cover 13, and the downward movement of the assembly box 12 causes the recycling equipment 31 to move downwards as well. The recycling device 31 pulls the support 41 downwards, and the support 41 pulls the sliding sleeve 421 downwards. Limited by the limiting rail 43, the two mounting rods 424 slide downwards on the outer side of the corresponding limiting rail 43. The two mounting rods 424 move closer together, and the mounting rods 424 drive the sliding rod 422 to slide in the sliding sleeve 421, thereby causing the left and right sets of pressure rollers 427 to move closer together. Because the rotating sleeve 425 can rotate on the mounting rods 424, the spring C428 pulls each set of two support rods 426, causing each set of two support rods 426 to move closer together. This causes the top two pressure rollers 427 and the bottom two pressure rollers 427 to clamp and seal the hose 322, achieving automatic sealing of the hose 322. The sealing is synchronized when the assembly box 12 moves downwards, preventing leakage of the recycled medium from the recycling device 31. The operation is simple.

[0030] After maintenance, a reset is performed. When spring B242 is retracted into the spring groove, spring A222 pushes assembly box 12 to reset it. At this time, the force of spring C428 pulling the two support rods 426 closer together will cause each set of two pressure rollers 427 to push hose 322. Because the two sets of pressure rollers 427 are aligned, the reaction force of the two sets of pressure rollers 427 pushing hose 322 will drive the two mounting rods 424 away from each other. The moving away of the mounting rods 424 will cause the sliding rods 422 to move away from each other and separate in the sliding sleeve 421. The stop block 423 prevents the sliding rods 422 from falling off. After reset, screw the female connector of the fixing tube C33 onto the screw end of the fixing tube B323 to complete the reset operation.
