[0004] The suction module arranged above the equipment installation position in the above-mentioned patent can rely on the fan to extract the airflow heated by the corresponding equipment installation position and blow it to the hot air channel through the blowing port, and cooperate with the hot air channel to form active heat dissipation, thereby avoiding the poor heat dissipation of some equipment installation positions in the electrical cabinet and achieving better heat dissipation effect. However, the long-term use of the dehumidification plate may affect the filtration, so the dehumidification plate needs to be replaced. However, the cabinet door needs to be opened when replacing the dehumidification plate.

[0014] The present invention provides a waterproof and dehumidifying electrical cabinet in a pump room. It has the following beneficial effects: (1) This invention increases the air circulation inside the cabinet casing by blowing air through a fan, and reduces the humidity inside the cabinet casing by absorbing moisture in the air through a dehumidifier. However, during long-term use, the dehumidifier needs to be replaced because it absorbs too much moisture. During the replacement process, the fan continues to operate. When one dehumidifier is replaced, the other dehumidifier will continue to dehumidify the air blown out of the air supply duct to prevent the air blown out of the air supply duct from being too humid, causing the moisture inside the cabinet casing to gather into water droplets, causing a short circuit in the circuit inside the cabinet casing, and affecting the normal use of the cabinet.

[0015] (2) This invention can only dehumidify when the cabinet door is closed. When the cabinet door is closed, the latch plate will move, and the movement of the latch plate will be inserted into the inside of the square plate. The insertion of the latch plate into the square plate will push the L-shaped rod to move to release the limit on the other side plate. When the latch plate is inserted into the inside of the square plate, the fixed plate will be inserted into the latch plate to limit the cabinet door. When the fan is started, the air blown into the inside of the electric cabinet shell will be dehumidified. During dehumidification, the cabinet door will be pulled back toward the inside of the electric cabinet shell to strengthen the sealing of the electric cabinet shell. Excessive moisture on the surface will enter the inside of the electric cabinet through the gap between the cabinet door and the electric cabinet shell, causing the excessive moisture inside the electric cabinet shell to gather into water droplets, causing a short circuit in the circuit inside the electrical cabinet, thereby affecting the normal use of the electrical cabinet.

[0016] (3) In the present invention, when the handle is turned, the push plate and the second inclined block will be driven to move. The movement of the second inclined block will push the short rod to move. The movement of the short rod will push the long rod to move. The movement of the long rod will push the connecting rod to move. The movement of the connecting rod will push the V-shaped rod to rotate. The heat dissipation net is cleaned by the rotation of the V-shaped rotating rod and the telescopic V-shaped rod to prevent the heat dissipation net from being blocked by impurities, which will affect the air supply of the fan to the inside of the electric cabinet housing, causing incomplete air supply of the fan, resulting in excessive moisture inside the electric cabinet housing, which will gather into water droplets and cause short circuit in the circuit inside the electric cabinet, thus affecting the normal use of the electric cabinet. The storage box is sealed by the sliding cover to prevent the impurities inside the storage box from flying out and sticking to the heat dissipation net when the fan is running. This will cause incomplete air supply of the fan, resulting in excessive moisture inside the electric cabinet housing, which will gather into water droplets and cause short circuit in the circuit inside the electric cabinet, thus affecting the normal use of the electric cabinet.
