Description

Technical Field

[0001] This utility model relates to the field of refrigeration unit technology, and in particular to a prefabricated energy station refrigeration unit. Background Technology

[0002] The refrigeration unit consists of a screw refrigeration compressor, condenser, evaporator, thermostatic expansion valve, oil separator, and air tank, plus components such as an oil sight glass, diaphragm manual valve, and return air filter.

[0003] The refrigeration compressor is the most important piece of equipment in a refrigeration unit, often referred to as the main unit. Refrigeration units have functions of supplying and exhausting air, as well as energy recovery. Their working principle and process are the same as those of a typical fresh air handling unit, except that an exhaust fan and a heat recovery device are added inside the unit. Together with the supply and return air ducts, they form a complete air exchange system. This system not only provides fresh air but also exhausts air and recovers energy from indoor air, making it both energy-efficient and environmentally friendly. It is a commonly used multi-functional fresh air handling unit.

[0004] The problem with the existing technology is that the refrigeration unit is installed inside the cabinet unit. During long-term operation, the blades of the refrigeration unit's exhaust outlet accumulate a thick layer of dust, which affects the rotation of the blades and thus affects the operation of the refrigeration unit. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a prefabricated energy station refrigeration unit to solve the problem of thick dust on the blades at the exhaust of the refrigeration unit.

[0006] To solve the above-mentioned technical problems, this utility model provides a prefabricated energy station refrigeration unit, including a cabinet unit and a protective cover set at the ventilation hole of the cabinet unit. A card seat is provided around the ventilation hole, and a card hole is provided on the card seat. A card block is provided around the protective cover, and a telescopic shaft is provided inside the card block. A pressing structure is provided above the card block. When the pressing structure is released, the telescopic shaft is locked into the card hole.

[0007] In a preferred embodiment, the pressing structure includes a button and a first spring disposed below the button. The button is an elongated structure consisting of a first part and a second part that smoothly transitions to the first part. The first part is larger than the second part. When the telescopic shaft is engaged in the locking hole, the telescopic shaft abuts against both sides of the first part.

[0008] In a preferred embodiment, a groove is provided inside the card block, a through hole is provided on one side of the groove, a telescopic shaft is inserted into the through hole, a cover plate is provided above the groove, a through groove is provided in the middle of the cover plate, and the button passes through the through groove.

[0009] In a preferred embodiment, a boss is provided on one side of the telescopic shaft, and a second spring is provided on the telescopic shaft between the boss and the through hole.

[0010] In a preferred embodiment, a recess is provided below the groove, and the first spring is installed in the recess.

[0011] In the preferred embodiment, the button has a rectangular cross-section.

[0012] In a preferred embodiment, the side of the button that contacts the telescopic shaft is coated with a wear-resistant material.

[0013] The beneficial effects of this utility model are as follows: By setting a mounting bracket on the cabinet unit and a locking block on the protective cover, when the button on the locking block is pressed, the telescopic shaft retracts, allowing the protective cover to be removed for easy cleaning of the exhaust blades inside the cabinet unit, preventing excessive dust from affecting the operation of the refrigeration unit. Furthermore, this operation is quick and efficient, saving time and effort compared to installing and removing the protective cover using screws. Attached Figure Description

Detailed Implementation

[0019] Please see Figure 1-3 As shown, this application provides a technical solution: a prefabricated energy station refrigeration unit, including a cabinet 11 and a cover 12 disposed at the ventilation hole of the cabinet 11. A card seat 13 is provided around the ventilation hole, and a card hole 131 is provided on the card seat 13. A card block 14 is provided around the cover 12, and a telescopic shaft 15 is provided inside the card block 14. A pressing structure is provided above the card block 14. When the pressing structure is released, the telescopic shaft 15 is inserted into the card hole 131.

[0020] In a preferred embodiment, the pressing structure includes a button 21 and a first spring 22 disposed below the button 21. The button 21 is a long strip structure consisting of a first part 211 and a second part 212 that smoothly transitions to the first part 211. The first part 211 is larger than the second part 212. When the telescopic shaft 15 is inserted into the card hole 131, the telescopic shaft 15 abuts against both sides of the first part 211.

[0021] The smooth transition between the first part 211 and the second part 212 facilitates the back-and-forth movement of the telescopic shaft 15 on the surfaces of the first part 211 and the second part 212.

[0022] In a preferred embodiment, a groove 141 is provided in the card block 14, and a through hole 142 is provided on one side of the groove 141. The telescopic shaft 15 is inserted into the through hole 142. A cover plate 16 is provided above the groove 141, and a through groove 161 is provided in the middle of the cover plate 16. The button 21 passes through the through groove 161.

[0023] The cover plate 16 can be detachably connected by clips or screws. The button 21 extends out of the cover plate 16 for easy pressing, and the cover plate 16 also serves as a dust cover.

[0024] In a preferred embodiment, a boss 17 is provided on one side of the telescopic shaft 15, and a second spring 18 is provided on the telescopic shaft 15 between the boss 17 and the through hole 142.

[0025] In a preferred embodiment, a recess 143 is provided below the groove 141, and the first spring 22 is installed in the recess 143.

[0026] In this way, when the second part 212 descends, it can be submerged in the pit 143.

[0027] In the preferred embodiment, the cross-section of button 21 is rectangular.

[0028] Button 21 is a rectangle so that the whole thing does not rotate.

[0029] In a preferred embodiment, the side of button 21 that contacts telescopic shaft 15 is coated with a wear-resistant material.

[0030] Wear-resistant materials can also be wear-resistant plates, such as copper plates, which can improve the wear resistance of button 21.

[0031] Thus, when button 21 is pressed, the first part 211 of button 21 descends, and the telescopic shaft 15 contacts the surface of the second part 212 under the action of the second spring 18. Because the size of the first part 211 is smaller than that of the second part 212, the telescopic shaft 15 retracts inward. At this time, the telescopic shaft 15 disengages from the locking hole 131, which is equivalent to the locking block 14 disengaging from the locking seat 13. At this time, the protective cover 12 can be removed for easy cleaning of dust on the exhaust blades. When button 21 is not pressed, the second part 212 rises under the action of the first spring 22 and contacts the surface of the telescopic shaft 15. At this time, the telescopic shaft 15 extends and locks into the locking hole 131, and the protective cover 12 is connected to the cabinet 11.

[0032] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
