Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning control cabinets, in particular to a protection device for a central air-conditioning control cabinet. Background Art

[0002] The central air conditioning control cabinet is assembled in a closed or semi-closed control cabinet with switchgear, measuring instruments, protective electrical appliances and auxiliary equipment according to the electrical wiring requirements. These electrical devices will generate a lot of heat when working, which will affect the normal operation of the electrical equipment and reduce the service life of the electrical equipment. Electricity will be consumed when using the refrigeration device.

[0003] For example, the central air-conditioning control cabinet in the Chinese patent (CN204438423U) includes a cabinet, a motor arranged on the top of the cabinet 1, a fan blade I installed on the motor output shaft and located at the top of the cabinet, a herringbone guide plate installed in the cabinet, a left heat dissipation fin and a right heat dissipation fin respectively arranged at the left and right ends of the guide plate, and an external heat dissipation fin installed on the back of the cabinet. The hot air flow is dispersed to the left and right sides after passing through the herringbone guide plate, and the heat pipes I and II on the left and right sides of the cabinet are respectively exchanged with the hot air flow dispersed to the two sides through the left heat dissipation fin and the right heat dissipation fin and the guide plate. After the heat pipes I and II absorb heat, the refrigerant inside becomes gas and evaporates obliquely upward to the external heat dissipation fin. After exchanging heat with the external environment through the external heat dissipation fin, it is condensed into liquid and flows back to the bottom of the heat pipes I and II. The cycle is repeated, and the heat in the cabinet is quickly discharged to the outside of the cabinet, thereby extending the service life of the air-conditioning control system.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

One end of the connecting rod 205 close to the slider 203 is hinged to the first hinge seat, and the end of the connecting rod 205 away from the slider 203 is hinged with an anti-collision plate 206. Two second hinge seats are fixed to the side of the anti-collision plate 206 close to the cabinet 1.

A buffer plate 209 is fixed to the end of the buffer rod 208 close to the cabinet 1, and one end of the inner wall of the sleeve 207 is abutted against a second spring 210.

[0025] The anti-collision mechanism 200 in this embodiment withstands the impact of foreign objects through the anti-collision plate 206.

[0027] See also Figure 1 and Figure 4In order to dissipate heat and cool down the cabinet 1, the heat dissipation and cooling mechanism 300 in this embodiment includes a water tank 301 fixed to the bottom side of the inner wall of the cabinet 1, and a plurality of heat dissipation fins 302 are fixed to the bottom end of the water tank 301, and the heat dissipation fins 302 extend to the bottom of the cabinet 1. The heat dissipation and cooling mechanism 300 also includes a heat conducting plate 303 fixed to the lower part between the left and right sides of the inner wall of the cabinet 1, and the top of the water tank 301 is fixed to the bottom side of the heat conducting plate 303. The inside of the heat conducting plate 303 and the partition 4 are both fixed with a first fan 304, and a drying box 305 is fixed between the bottom side of the heat conducting plate 303 and the bottom side of the inner wall of the cabinet 1.

[0028] The heat dissipation and cooling mechanism 300 in this embodiment reduces the temperature rise rate in the cabinet 1 through the water in the water tank 301. The heat conducting plate 303 is used to transfer the heat above the heat conducting plate 303 to the water tank 301. The heat dissipation fins 302 are used to conduct the heat in the water tank 301 to the outside of the cabinet 1. The drying box 305 is used to dry the air in the cabinet 1. The second fan 306 on the left is used to suck the outside air into the cabinet 1. The second fan 306 on the right is used to discharge the air in the cabinet 1.

[0029] It should be noted that the first fan 304 is used to guide the flow of air, and the dustproof net 307 is used to prevent dust from entering the cabinet 1.

[0030] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0031] The working principle of the above embodiment is:

[0032] When it is necessary to dissipate heat and cool down the cabinet 1, the second fan 306 and the first fan 304 are started. The second fan 306 on the left side draws the outside air into the cabinet 1. The air moves to the right side of the drying box 305 after being dried by the drying box 305. Then the first fan 304 introduces the air to the top of the heat conducting plate 303 and the partition 4. The newly-incoming air exchanges heat with the air carrying a large amount of heat. After that, the air is discharged from the cabinet 1 under the action of the second fan 306 on the right side. When the electrical appliances in the cabinet 1 generate a large amount of heat, the heat conducting plate 303 can transfer the heat above the heat conducting plate 303 to the water tank 301. The water in the water tank 301 has a large amount of heat. The heat is absorbed, and the heat dissipation fins 302 then conduct the heat in the water tank 301 to the outside of the cabinet 1, thereby achieving heat dissipation and cooling of the cabinet 1. When a foreign object hits the anti-collision plate 206, the anti-collision plate 206 drives the connecting rod 205 and the buffer rod 208 to move, and the connecting rod 205 drives the slider 203 to slide in the slide groove, and the slider 203 squeezes the first spring 204, and the first spring 204 deforms to buffer part of the impact force, and the buffer rod 208 drives the buffer plate 209 to squeeze the second spring 210, and the second spring 210 deforms to buffer another part of the impact force, thereby preventing the cabinet 1 from being knocked over.
