The distribution cabinet is the general term for the motor control center, and its main function is to distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby loads. However, the existing distribution cabinets have some deficiencies. For example:

[0003] For a distribution cabinet and a distribution cabinet group described in Application No. CN202210117612.3, since this device does not have an incoming and outgoing line sealing device, during outdoor use, it is very easy for internal cables to be short-circuited due to the infiltration of rainwater, causing potential safety hazards. Content of the Utility Model

[0004] The purpose of the utility model is to provide a limb rehabilitation assistor for stroke patients with a massage effect, so as to solve the problem in the above background art that the existing devices in the market do not have an incoming and outgoing line sealing device, resulting in the easy short-circuit of internal cables due to the infiltration of rainwater during outdoor use, causing potential safety hazards.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A sealing device for the incoming and outgoing lines of a distribution cabinet, including a diversion cover, an air inlet, a first negative pressure suction pipe, a sealing gasket, and a wire splitting gasket;

[0006] An air inlet is arranged above the diversion cover, and an air outlet is arranged on the right side of the bottom of the diversion cover. A motor and a vortex fan are installed above the midline of the diversion cover, and a first negative pressure suction pipe is arranged below the midline of the diversion cover. A sealing gasket is installed on the left side of the first negative pressure suction pipe.

[0007] As a preferred technical solution of the utility model, a circular air inlet is opened at the intersection of the diagonals at the top of the diversion cover, and the diversion cover is composed of two sections. The diameter of the lower part of the diversion cover is two-thirds of that of the upper part, and the connection area between the upper and lower parts of the diversion cover is set as an arc surface structure for transition;

[0008] By adopting the above technical solution, the device can quickly extract the surrounding hot air by opening a circular air inlet at the intersection of the diagonals at the top of the diversion cover, thereby effectively improving the heat dissipation efficiency of the device. And the connection area between the upper and lower parts of the diversion cover is set as an arc surface structure for transition, which can compress the flowing air, thereby effectively increasing the air flow rate.

[0009] As a preferred technical solution of the utility model, the bottom of the diversion cover is a bevel structure, and an air outlet is opened below the right side of the diversion cover. The air outlet faces the incoming line port direction;

[0010] With the above technical solution, the bottom of the fairing is of an inclined plane structure, which can prevent water from seeping in, thereby improving the waterproof performance of the device.

[0011] As a preferred technical solution of the present utility model, a motor is fixedly connected above the center line of the fairing. The motor is a waterproof motor, and the output shaft above the motor is fixedly connected to the vortex fan.

[0012] With the above technical solution, the device can reduce the levels of power transmission by fixedly connecting the output shaft above the motor to the vortex fan, thereby effectively improving the working efficiency of the device.

[0014] With the above technical solution, the device sucks in hot air through the vortex fan and compresses it through the fairing. When the high-speed air flow passes through the first negative pressure suction pipe installed obliquely, negative pressure will be generated at both ends through the through hole, thereby attracting the sealing rubber pad. While improving the sealing performance, the infiltrated water is discharged from the air outlet.

[0015] As a preferred technical solution of the present utility model, the first negative pressure suction pipe and the second negative pressure suction pipe face in opposite directions. The second negative pressure suction pipe is in a triangular posture, and a through hole is opened at the midpoint position of the top.

[0016] With the above technical solution, the device injects high-speed air flow into the second negative pressure suction pipe, generating pressure on the threaded film at the position of the connecting cap, causing the threaded film and the connecting cap to continuously squeeze, thereby improving the sealing performance of the device connection.

[0024] 5. The device injects high-speed air flow into the second negative pressure suction pipe, generating pressure on the threaded film at the connection cap position, causing the threaded film and the connection cap to continuously squeeze, thus improving the sealing performance of the device connection.

[0037] There is an air inlet 2 above the fairing 1. A circular air inlet 2 is opened at the intersection of the diagonals at the top of the fairing 1. The fairing 1 is divided into two sections. The diameter of the lower part of the fairing 1 is two-thirds of that of the upper part. The connection area between the upper and lower parts of the fairing 1 is set as an arc structure for transition. By opening a circular air inlet 2 at the intersection of the diagonals at the top of the fairing 1, the device can quickly extract the surrounding hot air, thus effectively improving the heat dissipation efficiency of the device.

There is an air outlet 5 on the right side at the bottom of the fairing 1. The bottom of the fairing 1 is a bevel structure, and an air outlet 5 is opened below the right side of the fairing 1. The air outlet 5 faces the direction of the wire inlet. By setting the bottom of the fairing 1 as a bevel structure, the device can prevent water from seeping in, thus improving the waterproof performance of the device. Above the center line of the fairing 1, a motor 6 and a vortex fan 7 are installed. The motor 6 is fixedly connected above the center line of the fairing 1. The motor 6 is a waterproof motor, and the output shaft above the motor 6 is fixedly connected to the vortex fan 7. By fixedly connecting the output shaft above the motor 6 to the vortex fan 7, the device can reduce the levels of power transmission, thus effectively improving the working efficiency of the device. Below the center line of the fairing 1, there is a first negative pressure suction pipe 3. A sealing gasket 4 is installed on the left side of the first negative pressure suction pipe 3.
