Description

Technical Field

[0001] The utility model relates to the technical field of PCS, and more particularly to a moisture-proof and windproof cover for PCS. Background Art

[0002] PCS usually refers to a power storage converter, which is an electric energy conversion and control device used in energy storage systems. It plays a vital role in power systems. The PCS booster is a special application form of PCS. It integrates power conversion and boost functions and is mainly used for power conversion and grid access in renewable energy systems. During its outdoor use, it needs to be protected by a windshield to prevent external rain and dust from affecting its internal working environment.

[0003] For example, a Chinese patent document (CN204796008U) discloses an outdoor electrical cabinet with good ventilation effect, comprising: a cabinet body, a top cover, an air inlet, an air outlet and an exhaust fan. The cabinet body has a cabinet door, and the cabinet door is connected to the cabinet body by a hinge. The top cover is trapezoidal and arranged at the upper end of the cabinet body. An exhaust cavity is formed in the top cover. The lower end surface area of ​​the top cover is larger than the cross-sectional area of ​​the cabinet body. An air outlet is provided on the lower end surface of the top cover and the outer side of the cabinet body, and an air inlet is provided on the lower back of the cabinet body. A fan is provided between the top cover and the cabinet body. An exhaust fan is provided, and wind shields are evenly provided on the inner wall of the cabinet, and a fixed connection is adopted between the wind shield and the cabinet. Through the above method, the utility model can reduce the temperature inside the electrical cabinet and increase the service life of electronic components. However, the product has poor protection and applicability during outdoor use. When used in bad weather, external dust and rainwater will enter the cabinet from the air inlet, resulting in an impact on its internal working environment, and then affecting the performance and service life of its internal components. Therefore, certain improvements are made. Utility Model Content

[0004] The purpose of the utility model is to provide a moisture-proof and windproof cover for PCS, which can protect the air inlet of the cabinet to prevent external rainwater and dust from entering the interior and affecting the internal working environment.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: A moisture-proof and windproof cover for PCS, comprising: a PCS cabinet, a plurality of windshields fixedly connected to one side of the top of the PCS cabinet by screws, a filter cleaning assembly provided inside the windshield, and an auxiliary cleaning assembly provided on the top of the filter cleaning assembly;

[0006] The filtering and cleaning assembly includes a filter screen, a first cavity is provided on one side of the filter screen, the first cavity is located inside the wind shield, a driving motor is fixedly connected to one side of the first cavity, one end of the output shaft of the driving motor is fixedly connected to a screw, a threaded sleeve is threaded on the screw, a vertical plate is fixedly connected to one side of the threaded sleeve, the vertical plate is slidably connected to the inside of the first cavity, a connecting block is fixedly connected to one side of the bottom of the vertical plate, and the other side of the connecting block extends to the bottom of the filter screen and is fixedly connected to multiple cleaning blocks by screws.

[0007] Furthermore, side panels are fixedly connected to both sides of the filter, and the side panels are fixedly connected to the inside of the windshield by screws.

[0008] Furthermore, circular through holes are provided on both sides of the threaded sleeve, and a limiting rod is slidably connected to the inside of the circular through hole, and both ends of the limiting rod are fixedly connected to the inner wall of the windshield.

[0009] Furthermore, the auxiliary cleaning component includes a rectangular block, which is arranged above the threaded sleeve, and one side of the rectangular block is fixedly connected to the vertical plate, and both sides of the rectangular block are fixedly connected to airbags, and the other side of the airbag is fixedly connected to the inner wall of the windshield.

[0010] Furthermore, one side of the airbag is connected to an air inlet pipe, and the other side of the airbag is connected to an air outlet pipe. Both the air outlet pipe and the air inlet pipe are provided with a one-way valve. A fixed block is provided at the other end of the air outlet pipe. One side of the fixed block is fixedly connected to the vertical plate. The fixed block is arranged on the side away from the rectangular block, and the fixed block is slidably connected to the inside of the windshield.

[0011] Furthermore, a second cavity is opened inside the fixed block, one side of the second cavity is connected to the air outlet pipe, and the bottom of the second cavity is connected to multiple air outlets, the air outlets are located inside the fixed block, and the fixed block is set above the filter.

[0012] Compared with the existing technology, the beneficial effects of this solution are as follows:

[0013] 1. This solution converts the air inlet perpendicular to the PCS cabinet into an air inlet at the wind shield by setting up a wind shield and a filter cleaning component. At this time, the air inlet is parallel to the PCS cabinet, that is, the direction of the PCS cabinet air inlet is changed by the added wind shield, and combined with the protective function of the wind shield, it can effectively reduce the probability of rainwater drifting into the PCS air inlet during windy and rainy weather, and reduce the chance of dust being brought into the PCS during strong winds, so as to help ensure the sanitary environment and dryness inside the PCS cabinet. The filter will filter the external air entering the wind shield and the PCS cabinet. The drive motor is started regularly according to actual needs, so that the drive motor will drive the screw to rotate, and the threaded sleeve will drive the vertical plate, connecting block and cleaning block to move back and forth in a straight line, so that the cleaning block can clean the filter to prevent the filter from being blocked after a long time, so as to prevent the air intake rate inside the wind shield from being affected.

[0014] 2. This solution uses the auxiliary cleaning components to enable the vertical plate to drive the rectangular block to move and spray the internal gas of the airbag through the outlet pipe, the second cavity and the air outlet to the top of the filter. At this time, with the cleaning effect of the cleaning block, the dust cleaned on the filter is discharged to the outside of the wind shield, preventing the dust from drifting into the inside of the wind shield during the cleaning process to prevent it from affecting the internal sanitary environment, thereby further ensuring the sanitary environment inside the PCS cabinet.
