Description

Technical Field

[0001] The utility model belongs to the technical field of prefabricated cabin installation, and in particular relates to a wind and sand proof structure for a prefabricated cabin. Background Art

[0002] The prefabricated cabin is an intelligent prefabricated cabin that integrates electrical equipment, control systems, protection devices and other functions. It is mainly used in power generation, transmission, distribution and other aspects of the power system. It adopts advanced modular design concepts and integrates traditional electrical equipment in a closed cabin, which has the advantages of high efficiency, environmental protection, safety and reliability.

[0003] In order to ensure ventilation in the prefabricated cabin, the prior art provides multiple fans on the outer wall of the prefabricated cabin to carry out air intake and exhaust inside the prefabricated cabin. In order to prevent wind and sand from entering the prefabricated cabin through the fans, most of the fans in the current domestic prefabricated cabin substations (prefabricated cabins) only provide an external dust cover as a measure to prevent wind and sand. However, in areas with strong winds and sand, the dust cover cannot completely isolate the fan, and wind and sand can easily enter the interior of the dust cover through the bottom of the dust cover, so wind and sand will still enter the cabin. Utility Model Content

[0004] The first aspect of the utility model aims to solve the problem that the existing fan only uses an external dust cover to prevent wind and sand, and there will still be wind and sand entering the cabin in strong wind and sand areas. A prefabricated cabin wind and sand protection structure is provided, which can be provided by arranging an inner filter screen inside the fan and an outer filter screen at the installation position of the fan and the prefabricated cabin. The main concept is:

[0005] A prefabricated cabin anti-wind and sand structure includes a prefabricated cabin, a fan, a filter assembly and a dust cover. The prefabricated cabin is provided with a fan installation port, and a filter assembly is arranged at the position of the fan installation port. The filter assembly is used to block wind and sand from entering the prefabricated cabin. The filter assembly includes an inner filter screen and an outer filter screen. The inner filter screen is installed inside the fan, and the outer filter screen is installed outside the fan. In this solution, on the basis of installing a dust cover outside the fan, a filter assembly is added to the installation position of the fan and the prefabricated cabin. The filter assembly is used to filter the wind and sand at the fan installation port provided on the prefabricated cabin, so that in a strong wind and sand environment, the wind and sand that cannot be blocked by the dust cover can be isolated again to prevent the wind and sand from entering the cabin.

[0006] Preferably, fan positioning components are arranged on both sides of the fan installation opening of the prefabricated cabin, the fan positioning components are installed on the side walls of the prefabricated cabin, and the fan positioning components are connected to the fan. The fan is positioned by the fan positioning components arranged on both sides of the fan installation opening, so as to avoid shaking of the fan at the fan installation opening and improve the stability of the fan.

[0007] The second aspect of the utility model aims to solve the technical problem that the gap between the fan installation hole and the fan is prone to the entry of wind and sand. Furthermore, the fan installation port of the prefabricated cabin is provided with a dust baffle, which is arranged on the outside of the fan, and the outer filter is arranged between the fan and the dust baffle. The dust baffle is installed on the fan installation port, and the end of the outer filter is abutted against the dust baffle, so that the part where the fan installation port and the outer filter are not tightly sealed is blocked by the wind baffle; in addition, under the action of the fan positioning assembly, the installed fan can support the two end faces of the outer filter together with the dust baffle, so that the outer filter can be stably assembled at the fan installation port without mechanical installation.

[0008] The third aspect of the utility model aims to enable the internal filter screen inside the fan to be quickly cleaned. Furthermore, the filter assembly also includes filter cotton, which is bonded to the outside of the inner filter screen. In this solution, filter cotton is laid on the outside of the inner filter screen by bonding, and the filter cotton is arranged between the inner filter screen and the outer filter screen. The wind and sand that are not filtered by the outer filter screen enter the fan installation port and are then filtered by the inner filter screen. The filter cotton is pasted on the inner filter screen so that the wind and sand that enter the fan position adhere to the filter cotton. When the fan needs to be cleaned, the filter cotton can be torn off to quickly clean the internal filter screen.

[0009] The fourth aspect of the utility model aims to solve the problem that the air-conditioning outdoor unit outside the prefabricated cabin is subjected to the wear and tear of the wind and sand in a strong wind and sand environment, resulting in the shortening of the life of the air-conditioning outdoor unit. Further, it also includes an air-conditioning outdoor machine box, which is installed outside the prefabricated cabin, and the air-conditioning outdoor machine box is installed inside the air-conditioning outdoor machine box. This solution prevents the wind and sand from directly acting on the air-conditioning outdoor unit by installing the air-conditioning outdoor machine box outside the air-conditioning outdoor unit, thereby avoiding the wear and tear of the air-conditioning outdoor unit by the wind and sand, and prolonging the service life of the air-conditioning outdoor unit.

[0010] Preferably, the air conditioner outdoor case includes a plurality of ventilation panels, and the plurality of ventilation panels are connected by angle steels.

[0011] Preferably, the ventilation plate is provided with a plurality of ventilation holes. The outdoor air conditioner generates a large amount of heat during operation, and the provision of ventilation holes can facilitate heat dissipation of the outdoor air conditioner.

[0012] Preferably, the vent holes are louver holes opening downwards. The opening direction of the vent holes is set at the side position, and when the air conditioner outdoor unit is dissipating heat, it prevents wind and sand from directly entering the interior of the air conditioner outer case.

[0013] The beneficial effects of the utility model are:

[0014] On the basis of installing a dust cover outside the fan, a filter component is added to the installation position of the fan and the prefabricated cabin. The filter component is used to filter the wind and sand at the fan installation port opened on the prefabricated cabin, so that in a strong wind and sand environment, the wind and sand that cannot be blocked by the dust cover can be isolated again to prevent the wind and sand from entering the cabin.
