It has been widely used in airports, subway stations, stations, docks, scenic spots, parks, student dormitories, unit pedestrian channels, etc. It can be used with smart cards to realize the function of offline ticket management system and form unattended management of personnel entry and exit. The wing gate needs a worm gear reduction motor during operation so that the gate on the wing gate can be rotated and adjusted.

[0003] The existing worm gear reduction motor lacks a heat dissipation structure, and the worm gear mechanism inside the reduction box tends to heat up too quickly during frequent operation, which makes the reduction box easily damaged due to high temperature. Utility Model Content

By arranging a temperature sensor, heat dissipation ribs, a fixing ring, a heat dissipation motor and heat dissipation fan blades, the temperature sensor can detect the temperature of the reduction box. When the temperature exceeds the set value, the heat dissipation motor starts, and then the heat dissipation fan blades rotate to perform air cooling and heat dissipation on the heat dissipation ribs, thereby preventing the reduction box from being damaged due to high temperature, and can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] Furthermore, a fixing ear plate is arranged on the outer side of the upper part of the DC motor, and a bolt hole is arranged on the outer shell of the reduction box.

[0008] Furthermore, a connecting wire is arranged on the upper part of the DC motor, and a keyway is arranged on the output shaft.

[0009] Furthermore, the heat dissipation ribs are integrally formed with the reduction box housing, and the reduction box is connected to the DC motor via bolts.

[0010] Furthermore, the fixing ring is welded to the heat dissipation ribs, and the fixing ring is connected to the heat dissipation motor via screws.

[0011] Furthermore, the temperature sensor is connected to the reduction box via screws, and the output end of the heat dissipation motor is keyed to the heat dissipation fan blade.

[0012] Furthermore, the fixing ring and the heat dissipation ribs are both made of stainless steel.

[0013] The utility model arranges a temperature sensor, heat dissipation ribs, a fixing ring, a heat dissipation motor and heat dissipation fan blades, so that the temperature sensor can detect the temperature of the reduction gear box. When the temperature exceeds the set value, the heat dissipation motor starts, thereby causing the heat dissipation fan blades to rotate to perform air cooling on the heat dissipation ribs, thereby preventing the reduction gear box from being damaged due to high temperature.

[0025] The heat dissipation ribs 9 are integrally formed with the outer shell of the reduction box 2, and the reduction box 2 is connected to the DC motor 1 by bolts.

[0032] When it is needed, it is connected and fixed to the supporting structure of the wing gate through the bolt holes 7 on the reduction box 2. The DC motor 1 is decelerated by the reduction box 2 and the power is output through the output shaft 4. The temperature sensor 12 can monitor the temperature of the reduction box 2 in real time.
