The utility model discloses a connecting node of a prefabricated air conditioner plate and a prefabricated shear wall, which relates to the technical field of prefabricated building structures and comprises a prefabricated shear wall main body, a convenient connecting mechanism is arranged on the inner wall of the prefabricated shear wall main body, and a waterproof treatment mechanism is arranged on the left side of the prefabricated shear wall main body. The convenient connecting mechanism comprises an inserting strip plate, and the inserting strip plate is detachably connected to the inner wall of the prefabricated shear wall body. Through the elastic design of the elastic pieces, a user can compress the elastic pieces, so that the branch inserting columns contract towards the inner cavities of the connecting working grooves, then the branch inserting columns can be reset and inserted into the connecting pin holes of the inserting battens through the reset elastic force of the elastic pieces, and the inserting battens are locked in the inner cavities of the prefabricated shear wall body; the function that the prefabricated air conditioner plate is conveniently installed on the side face of the prefabricated shear wall body is achieved, the assembly speed of a building is increased, and the high efficiency of the structure is improved.

The present invention provides an air conditioning housing and an air conditioner, and relates to the technical field of air conditioning. The air conditioning housing includes a top cover plate and a casing, the top cover plate is buckled on the top of the casing, and the top cover plate and the casing are arranged to form an inner cavity for accommodating a compressor; the outer wall of the casing is provided with a heat dissipation groove, the upper part of the heat dissipation groove is connected with the inner cavity, so that the heat of the inner cavity is dissipated to the external space through the heat dissipation groove, and the top cover plate shields the upper part of the heat dissipation groove to prevent rainwater from flowing into the inner cavity from the upper part of the heat dissipation groove. Compared with the prior art, the air conditioning housing provided by the present invention shields the heat dissipation groove by the top cover plate, so that it is difficult for rainwater to enter the heat dissipation channel under the action of gravity and then enter the inner cavity through the upper opening, thereby realizing the rainproof function, and at the same time, the heat dissipation effect can be ensured through the heat dissipation channel.

This invention discloses a rainproof and heat dissipation system and control method for photovoltaic transformer substations, relating to the field of photovoltaic power station technology. The rainproof and heat dissipation system includes a transformer substation housing, a first air inlet, a first exhaust outlet, a first exhaust power component, a second air inlet, a second exhaust outlet, a second exhaust power component 51, an internal circulation power component, an opening adjustment device, and a control device. The first air inlet is located at the lower part of the housing housing; the first exhaust outlet is located at the top of the housing housing; the second air inlet is located at the upper part of the housing housing; the second exhaust outlet is located on the side wall of the housing housing opposite to the second air inlet; and the internal circulation power component is located inside the housing housing. During rainfall, the rainproof and heat dissipation system provided in this application can achieve rainproof function by reducing or closing the first air inlet and / or the second air inlet, while simultaneously achieving internal circulation heat dissipation through the internal circulation power component. This effectively solves the problem of the conflict between rainproofing and heat dissipation.
