[0002] A refrigeration unit is a device used for refrigeration. Its core function is to cool down the environment by transferring heat to the ambient medium. It is widely used in civil, industrial, agricultural production and other fields, including air conditioning, industrial cold chain cold storage and other occasions that require refrigeration.

[0003] In a refrigeration unit, the condenser is a key heat exchanger in the refrigeration cycle, responsible for heat dissipation and heat absorption. Since refrigeration units have a wide range of applications, their installation environments are different. Traditional refrigeration units lack certain protective mechanisms. During actual use, the surface of the condenser may be adsorbed and blocked by a large amount of dust and debris, resulting in a decrease in its heat exchange efficiency. In addition, during the fan operation, foreign objects such as gravel may be drawn in, which may cause damage to the internal components of the refrigeration unit. Therefore, a refrigeration unit with a protective mechanism is urgently needed. Utility Model Content

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-6 A refrigeration unit with a protective mechanism includes a refrigeration unit body 1, a casing 2 is arranged on the upper part of the refrigeration unit body 1, a fixing frame 9 is installed on one side of the inner part of the casing 2, a plurality of movable plates 5 are rotatably installed inside the fixing frame 9 through a torsion spring shaft 51, one side of each movable plate 5 is limitedly connected with a connecting rod 12 through a connecting rod 52, the connecting rod 12 is installed on one side of the fixing frame 9, and a filter screen 8 is installed on the other side of the fixing frame 9 through a connecting column 11.

[0026] Among them, a plurality of air inlet fans 3 are installed at one end of the casing 2 .

[0027] In addition, a connecting rod 12 is installed in the middle of one side of the fixing frame 9 for limited movement, and a spring 14 is fixedly installed at the bottom of the connecting rod 12. The bottom of the spring 14 is installed in a telescopic groove 15 opened at the bottom of the fixing frame 9, and the connecting rod 12 is limited to move in the telescopic groove 15.

[0028] Furthermore, a sliding groove 16 is provided on an upper portion of one side of the fixing frame 9 , and a trigger handle 10 is slidably installed in the sliding groove 16 . One end of the trigger handle 10 extends into the fixing frame 9 and is fixedly connected to the connecting rod 12 .

[0029] Furthermore, both sides of the movable plate 5 are rotatably mounted on one side of the inner wall of the fixed frame 9 through a torsion spring shaft 51, and each movable plate 5 is arranged in a mirror-image manner, and a connecting rod 52 is installed on one side of each movable plate 5, a through hole is opened at one end of the connecting rod 52, and the connecting rod 52 is sleeved and mounted on the connecting rod 12.

[0030] Furthermore, a plurality of conical cylinders 13 are mounted on the connecting rod 12 , with the narrow ends of the conical cylinders 13 facing downward, and connecting rods 52 are disposed directly below the conical cylinders 13 . When the conical cylinders 13 move, the conical cylinders 13 are in compression contact with the connecting rods 52 .

[0031] Furthermore, a collecting frame 4 is fixedly mounted on one side of the bottom of the fixing frame 9. The collecting frame 4 can collect the large particles of dust and gravel after cleaning.

[0032] Furthermore, a plurality of grid plates 53 are provided on the movable plate 5. The grid plates 53 can effectively block the rolled-in gravel.

[0033] In this embodiment, during the actual use of the refrigeration unit body 1, the air inlet fan 3 provides the condenser group 7 arranged inside the casing 2 with basic heat dissipation benefits, and ensures the normal heat exchange operation of the refrigeration unit body 1. In actual application, the air inlet fan 3 introduces external dust and large dust particles into the casing 2. At the same time, the multiple movable plates 5 staggered inside can block most of the large particles and block them through the grille 53. The subsequent dust will be further blocked by the filter 8, which effectively improves the protection performance inside the casing 2 and prevents dust from entering the condenser group 7.

[0034] At the same time, due to the setting of the movable plate 5, it can block foreign objects such as gravel and flying insects that may exist in the installation environment, and protect the internal condenser group 7 to avoid damage to the body caused by the entry of foreign objects. At the same time, after long-term use, by opening the inspection panel 6 on one side of the casing 2, the inspection panel 6 is opened to quickly press the trigger handle 10 on the fixing frame 9. Under the effect of the quick pressing, the trigger handle 10 quickly moves in the sliding groove 16, and the trigger handle 10 drives the connecting rod 12 to move up and down. Due to the connection between the connecting rod 12 and the spring 14, the spring 14 is released. The spring 14 can provide the function of rebounding and restoring the connecting rod 12 each time it moves up and down. At the same time, when the connecting rod 12 moves up and down, the conical tube 13 on the connecting rod 12 presses the connecting rod 52. The through hole opened in the middle of the connecting rod 52 is larger than the diameter of the connecting rod 12 to ensure a certain degree of activity. After being pressed by the conical tube 13, the connecting rod 52 slides on the connecting rod 12. At this time, the connecting rod 52 drives the movable plate 5 to rotate. Under the action of frequent rotation, large particles and gravel blocked on the movable plate 5 will fall into the collection frame 4 below for collection.

[0035] Then, the internal filter 8 will further absorb the dust to prevent the dust from entering the body and interfering with the heat exchange efficiency of the condenser group 7, thereby effectively improving its protection performance.

[0036] The two sides of the movable plate 5 are connected by a torsion spring shaft 51, in which a torsion spring is arranged. The torsion spring cooperates with the shaft to ensure that the movable plate 5 always has a torsion force in the opposite direction when it rotates.

[0037] In the utility model, by arranging a plurality of staggered movable plates 5 inside the casing 2 and cooperating with the filter screen 8 on the inner side, foreign matter and dust in the working environment can be effectively blocked and alleviated, and the situation where foreign matter such as gravel damages the internal components can be avoided. At the same time, the setting of the filter screen 8 can effectively reduce the dust from entering the body, effectively improve the protective performance of the body, and thus improve the overall heat exchange efficiency of the equipment.

[0038] At the same time, after long-term use, the inspection panel 6 can be opened and the internal trigger handle 10 can be repeatedly pressed. At the same time, the connecting rod 12 drives the connecting rod 52 to make the movable plate 5 rotate quickly, thereby clearing the gravel and large foreign matter that are stuck or adsorbed on the movable plate, and collecting and recycling them through the collection frame.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
