[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4This utility model provides a technical solution: a refrigeration unit for easy disassembly and assembly of refrigeration and air conditioning equipment, including a refrigeration device 1; the refrigeration device 1 consists of a body 2 and an outer shell 17, the outer shell 17 is installed on the upper side of the body 2, a base plate 12 is installed at the bottom end of the body 2, a base 13 is installed at the bottom end of the base plate 12, a shock-absorbing mechanism 23 is installed between the base 13 and the base plate 12, a guide mechanism 21 is installed between the base plate 12 and the base 13, a first maintenance door 3 is installed around the outer shell 17, and a second maintenance door 7 is installed on both sides of the body 2. An exhaust mechanism 8 is installed on the upper side of the housing 17. An air inlet 4 is installed on the upper side of the first inspection door 3. A filter screen 5 is installed inside the air inlet 4. A cleaning mechanism 11 is installed on the upper side of the filter screen 5. A control mechanism 28 is installed on the upper side of the cleaning mechanism 11. The first inspection door 3 is rotatably installed on one side of the housing 17 via a hinge 6. The second inspection door 7 is rotatably installed on one side of the body 2 via a hinge 6. The other side of the first inspection door 3 is installed on the upper side of the housing 17 via a fixing mechanism 10. The second inspection door 7 is installed on the other side of the body 2 via a fixing mechanism 10.

[0027] Furthermore, the exhaust mechanism 8 consists of a fan 15 and an air outlet 14. The air outlet 14 is installed on the upper side of the outer casing 17, and the fan 15 is installed inside the air outlet 14. The exhaust mechanism 8 generates airflow power by operating the fan 15 installed inside the air outlet 14. When the fan 15 starts, it creates a negative pressure environment inside the outer casing 17, causing external air to enter the refrigeration device 1 from the air inlet 4. After being refrigerated, the air is discharged through the air outlet 14, forming a continuous air circulation convection, thereby achieving heat exchange and diffusion of the cooling effect.

[0028] Furthermore, a protective sleeve 18 is provided between the base plate 12 and the base 13. The protective sleeve 18 is attached to the bottom of the base plate 12 and the upper side of the base 13 with adhesive. The protective sleeve 18 uses its own flexible material to wrap the shock absorption mechanism 23 and the guide mechanism 21. On the one hand, it can prevent external dust, moisture and other impurities from entering the interior of the mechanism and affecting its operation. On the other hand, it can reduce the transmission of noise generated during the operation of the mechanism. At the same time, it can prevent the base plate 12 and the base 13 from directly rubbing against each other and causing wear, thus playing a dual role of protection and sealing.

[0029] Furthermore, the guiding mechanism 21 consists of a guide rod 25, a through hole 20, and a limiting plate 24. The bottom end of the guide rod 25 is welded to the upper side of the base 13. The through holes 20 are located on both sides of the bottom end of the base plate 12. The upper end of the guide rod 25 extends through the through hole 20 and out of the upper side of the base plate 12. The limiting plate 24 is welded to the upper side of the guide rod 25. When the equipment vibrates or is subjected to external force during operation, the base plate 12 will undergo a slight displacement relative to the base 13. At this time, the guide rod 25 fixed on the base 13 will slide vertically along the through holes 20 on both sides of the base plate 12. The cooperation between the guide rod 25 and the through hole 20 restricts the horizontal displacement of the base plate 12, preventing it from shifting or tilting. The limiting plate 24 at the top prevents the guide rod 25 from detaching from the through hole 20, ensuring that the base plate 12 always moves within a preset range and ensuring the stability of the overall structure of the equipment.

[0030] Furthermore, the vibration damping mechanism 23 consists of a spring 19 and a damper 22, which are evenly installed on the upper side of the base 13 and the bottom of the base plate 12. When the equipment vibrates during operation, the spring 19 between the base 13 and the base plate 12 absorbs the vibration energy through its own elastic deformation, converting the vertical impact force into elastic potential energy. At the same time, the damper 22 uses its internal damping medium, such as oil, to generate resistance, suppressing the reciprocating vibration of the spring 19 and causing the vibration energy to decay rapidly. The synergistic effect of the spring 19 and the damper 22 can effectively reduce the vibration amplitude and noise during equipment operation, protecting internal components from vibration damage.

[0031] Furthermore, the fixing mechanism 10 consists of a handle 9 and a fixing bolt 26. The handle 9 is welded to one side of the fixing bolt 26. The fixing bolt 26 is rotatably installed on the upper side of the first inspection door 3 and the second inspection door 7. The fixing bolt 26 is rotatably installed inside the screw holes on the upper side of the outer casing 17 and the upper side of the machine body 2. When it is necessary to fix the first inspection door 3 or the second inspection door 7, the fixing bolt 26 is rotated by rotating the handle 9, so that the fixing bolt 26 is screwed into the corresponding screw hole on the outer casing 17 or the machine body 2. The self-locking property of the threaded connection is used to firmly fix the inspection door to the equipment. When it is necessary to disassemble the first inspection door 3 or the second inspection door 7, the fixing bolt 26 is disengaged by rotating the handle 9 in the opposite direction. The fixing can be released, and the first inspection door 3 or the second inspection door 7 can be opened by hinge 6. This structure does not require additional tools and can be quickly disassembled and assembled by manual operation, which greatly improves the convenience of maintenance.

[0032] Furthermore, the cleaning mechanism 11 consists of a motor 27, a scraper 30, and a cleaning brush 31. The cleaning brush 31 is installed inside the scraper 30, with one side in contact with the filter screen 5. The middle end of the scraper 30 is mounted on the front section of the motor 27, and the motor 27 is installed inside the filter screen 5. After the motor 27 starts, it drives the front scraper 30 to rotate. Because the cleaning brush 31 inside the scraper 30 is in contact with the surface of the filter screen 5, it wipes the filter screen 5 as the scraper 30 rotates, sweeping away the dust and debris attached to the filter screen 5, preventing the filter screen 5 from becoming clogged. This mechanical cleaning method replaces manual cleaning, ensuring smooth airflow at the air inlet 4 and maintaining the heat exchange efficiency of the refrigeration unit 1.

[0033] Furthermore, the control mechanism 28 consists of an automatic controller 29 and a differential pressure sensor 16. The differential pressure sensor 16 is installed on both the inner and outer sides of the upper end of the housing 17, and the automatic controller 29 is installed on the upper side of the motor 27. The automatic controller 29 and the differential pressure sensor 16 are electrically connected by a wire. The differential pressure sensor 16 monitors the air pressure difference between the inner and outer sides of the housing 17 in real time. When the accumulated impurities on the filter screen 5 increase, causing the air intake resistance to increase, the air pressure difference between the inner and outer sides will exceed a preset threshold. At this time, the differential pressure sensor 16 transmits a signal to the automatic controller 29 through the wire. After receiving the signal, the automatic controller 29 starts the motor 27 of the cleaning mechanism 11, triggering the cleaning action. When the impurities are removed and the air pressure difference returns to the normal range, the automatic controller 29 then controls the motor 27 to stop running, realizing the intelligent automatic cleaning of the filter screen 5.

[0034] Furthermore, a conical perforated plate 32 is installed inside the first inspection door 3 at the air inlet 4. The conical perforated plate 32 is installed inside the first inspection door 3. The conical perforated plate 32 uses a conical structure to guide and divert the incoming airflow, so that the air forms a uniform airflow distribution before entering the filter screen 5, avoiding excessively high local wind speeds that would cause impurities to concentrate and adhere to a certain area of ​​the filter screen 5. At the same time, the conical structure can increase the airflow speed and improve the heat dissipation effect.

[0035] Working Principle: In this refrigeration unit for easy assembly and disassembly, the refrigeration device 1 first forms a closed refrigeration space through the combination of the body 2 and the outer casing 17. The bottom plate 12 and the base 13 at the bottom of the body 2 form a stable support structure. The shock-absorbing mechanism 23 between the base 13 and the bottom plate 12 can buffer the vibration during equipment operation. The guide mechanism 21 ensures that the base plate 12 and the base 13 maintain accurate positioning when they move relative to each other. The first access door 3 around the outer casing 17 and the second access door 7 on both sides of the body 2 are opened and closed by hinges 6, in conjunction with the fixing mechanism. 10 allows for quick assembly and disassembly – when maintenance is required, simply loosen the fixing mechanism 10 to open the maintenance door, and re-fix it after the operation to restore the closed state. The exhaust mechanism 8 on the upper side of the outer casing 17 accelerates air circulation, the filter 5 of the air inlet 4 intercepts impurities in the air, the cleaning mechanism 11 automatically cleans the filter 5, and the control mechanism 28 adjusts the cleaning action according to the operating status. The overall structure not only ensures the stable operation of the refrigeration system, but also greatly improves the equipment maintenance efficiency through the convenient design of the maintenance door and the automatic cleaning function of the filter 5.

[0036] This is the characteristic of refrigeration units for refrigeration and air conditioning equipment that are easy to install and disassemble. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
