Description

Technical Field

[0001] This utility model relates to the technical field of heat source replenishment equipment, and in particular to a heat source replenishment equipment for a refrigeration machine that is easy to maintain. Background Technology

[0002] During the operation of a refrigeration unit, a stable heat source is often required to maintain its specific refrigeration cycle and performance.

[0003] Traditional heat source replenishment equipment often has a complex structure and compact internal component layout, resulting in limited operating space and making disassembly and assembly tools difficult to operate, increasing the difficulty of disassembly and maintenance. Once a component fails, maintenance personnel need to spend a lot of time disassembling and troubleshooting, which not only increases equipment downtime and reduces production efficiency, but also, due to the complexity of the maintenance process, may lead to misoperation or damage to other components, further increasing maintenance costs and equipment failure risks. Therefore, we propose an easy-to-maintain refrigeration heat source replenishment equipment to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an easy-to-maintain heat source replenishment device for refrigeration machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An easy-to-maintain refrigeration unit heat source replenishment device includes a mounting shell, a protective shell, and a heat source generator for replenishing the refrigeration unit heat source. A sealing plate is installed on the top of the mounting shell, and the heat source generator is installed on the sealing plate. The protective shell is installed on the top of the mounting shell and is sealed to the sealing plate. The heat source generator is installed inside the protective shell. A door is provided on the front side of the protective shell. Two drive seats are provided on the top of the mounting shell. Fixing plates are fixedly installed on both sides of the top of the protective shell, and a fixing mechanism is provided between the fixing plates and the drive seats. A rotating hole is opened on the inner wall of the top of the protective shell, and a threaded rod is rotatably installed in the rotating hole. A threaded groove is opened on the bottom of the drive seat, and the threaded rod is threadedly installed in the threaded groove.

[0007] Preferably, drive shafts are rotatably mounted on the inner walls of both sides of the mounting housing, and a drive motor is fixedly mounted on one side of the mounting housing, with the output shaft of the drive motor fixedly connected to the corresponding drive shaft.

[0008] Preferably, bevel gears are fixedly installed on both the drive shaft and the bottom end of the threaded rod, and the corresponding two bevel gears mesh with each other.

[0009] Preferably, the fixing mechanism includes a mounting hole, a fixing screw, and a fixing nut. The mounting hole is formed on the fixing plate, the fixing screw is fixedly installed on the top of the drive seat, and the fixing screw passes through the corresponding mounting hole and is threaded with a fixing nut.

[0010] Preferably, a connecting plate is fixedly installed on both sides of the protective shell, and a rectangular hole is opened on the connecting plate, and the drive seat passes through the corresponding rectangular hole.

[0011] Preferably, a bolt hole is provided on one inner wall of the rectangular hole, and a fixing bolt is installed in the bolt hole with internal thread, and the fixing bolt is in close contact with the drive seat.

[0012] Preferably, the bottom of the drive seat is provided with a rectangular groove, and two rectangular rods are fixedly installed on the top of the mounting shell, and the rectangular rods are slidably installed in the rectangular groove.

[0013] Preferably, the protective shell has heat dissipation holes on its rear inner wall, and the fireproof shell has wire holes with open bottoms on its rear inner wall.

[0014] The beneficial effects of this utility model are:

[0015] 1. The protective shell can protect the heat source generator, which can supplement the heat source of the refrigeration unit. When the heat source generator needs maintenance, the drive motor can drive the drive base to move. The two drive bases can push the same protective shell upward through the fixing plate, so that the protective shell is moved above the heat source generator, thus facilitating the maintenance of the heat source generator.

[0016] 2. By rotating the fixing nut, the fixing nut is separated from the fixing screw. By rotating the fixing bolt, the fixing bolt can be moved while rotating under the action of the bolt hole, so that the fixing bolt is separated from the drive seat. This can release the fixing of the protective shell, thereby achieving the purpose of disassembling and assembling the protective shell. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses an easy-to-maintain heat source replenishment device for a refrigeration unit.

[0025] Reference Figure 1-5 An easy-to-maintain refrigeration heat source replenishment device includes a mounting shell 1, a protective shell 2, and a heat source generator 3 for replenishing the refrigeration heat source. A sealing plate 202 is installed on the top of the mounting shell 1, and the heat source generator 3 is installed on the sealing plate 202. The protective shell 2 is installed on the top of the mounting shell 1 and is sealed to the sealing plate 202. The heat source generator 3 is installed inside the protective shell 2. A door 201 is provided on the front side of the protective shell 2. Two drive seats 403 are provided on the top of the mounting shell 1. Fixing plates 8 are fixedly installed on both sides of the top of the protective shell 2, and a fixing mechanism is provided between the fixing plates 8 and the drive seats 403. A rotating hole 503 is opened on the inner wall of the top of the protective shell 2. A threaded rod 502 is rotatably installed in the rotating hole 503. A threaded groove 501 is opened on the bottom of the drive seat 403, and the threaded rod 502 is threadedly installed in the threaded groove 501.

[0026] Specifically, drive shafts 601 are rotatably mounted on the inner walls of both sides of the mounting housing 1. A drive motor 602 is fixedly mounted on one side of the mounting housing 1, and the output shaft of the drive motor 602 is fixedly connected to the corresponding drive shaft 601. Bevel gears 603 are fixedly mounted on the drive shaft 601 and the bottom end of the threaded rod 502, and the two corresponding bevel gears 603 mesh with each other. More specifically, there are two bevel gears on the drive shaft 601. By starting the drive motor 602, the drive motor 602 can drive the drive shaft 601 to rotate. The drive shaft 601 can drive the threaded rod 502 to rotate through the bevel gears 603. At this time, the two threaded rods 502 can rotate synchronously.

[0027] Specifically, the fixing mechanism includes a mounting hole 801, a fixing screw 802, and a fixing nut 803. The mounting hole 801 is formed on the fixing plate 8. The fixing screw 802 is fixedly installed on the top of the drive seat 403. The fixing screw 802 passes through the corresponding mounting hole 801 and is threaded with the fixing nut 803. By setting the fixing screw 802 and the fixing nut 803, the fixing plate 8 and the drive seat 403 can be fixedly connected. Both sides of the protective shell 2 are fixedly installed with connecting plates 701. The connecting plates 701 have rectangular holes 702, and the drive seat 403 passes through the corresponding rectangular holes 702. A bolt hole 703 is formed on the inner wall of one side of the rectangular hole 702. A fixing bolt 704 is threaded into the bolt hole 703, and the fixing bolt 704 is in close contact with the drive seat 403. By setting the fixing bolt 704, the stability of the connection between the protective shell 2 and the drive seat 403 can be increased.

[0028] Specifically, a rectangular groove 401 is provided at the bottom of the drive seat 403, and two rectangular rods 402 are fixedly installed on the top of the mounting shell 1. The rectangular rods 402 are slidably installed in the rectangular groove 401. By providing the rectangular rods 402 and the rectangular groove 401, the drive seat 403 can slide on the rectangular rods 402. At the same time, the drive seat 403 cannot detach from the rectangular rods 402, thereby preventing the threaded rod 502 from separating from the threaded groove 501. A heat dissipation hole is provided on the rear inner wall of the protective shell 2, and a wire hole with an open bottom is provided on the rear inner wall of the fireproof shell. The heat dissipation hole can dissipate heat from the heat source generator 3, and the wire hole facilitates the passage of the heat source generator 3's wiring and pipes through the protective shell 2.

[0029] The working principle of this utility model is as follows: The protective shell 2 protects the heat source generator 3, which provides heat to the refrigeration unit. When maintenance of the heat source generator is required, the drive motor 602 is started, which drives the drive shaft 601 to rotate. The drive shaft 601 drives the threaded rod 502 to rotate via the bevel gear 603. The threaded rod 502 drives the drive seat 403 to move upward via the threaded groove 501. The two drive seats 403 push the same protective shell 2 upward via the fixing plate 8, so that the protective shell 2 is above the heat source generator 3, making it easier to maintain the heat source generator 3. By rotating the fixing nut 803, the fixing nut 803 is separated from the fixing screw 802. By rotating the fixing bolt 704, the fixing bolt 704 can rotate and move simultaneously under the action of the bolt hole 703, so that the fixing bolt 704 is separated from the drive seat 403, thereby releasing the fixing of the protective shell 2 and achieving the purpose of disassembling and assembling the protective shell 2.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
