Description

Technical Field

[0001] The utility model relates to the technical field of servo motors, in particular to an explosion-proof servo motor. Background Art

[0002] Explosion-proof servo motors are mainly used in the transportation and production of flammable and explosive goods. Explosion-proof servo motors are fully sealed servo motors, which can prevent the electric sparks generated by the motor from igniting flammable goods. Due to the fully sealed design, the internal temperature of the explosion-proof servo motor is prone to high temperature when running at high load for a long time, which in turn affects its service life.

[0003] Therefore, it is necessary to focus on solving the heat dissipation problem of explosion-proof servo motors. Existing heat dissipation technologies include air cooling and water cooling. However, no matter which heat dissipation form is used, the existing technology requires electric equipment to drive the fan blades or circulating pumps. The addition of electric equipment will increase the probability of electric sparks, thereby increasing the risk of fire. Utility Model Content

[0004] The purpose of the present utility model is to provide an explosion-proof servo motor in order to solve the above problems, as described below.

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

[0006] The utility model provides an explosion-proof servo motor, comprising a servo motor, wherein the surface of the servo motor is wrapped with two water tanks, and the two water tanks are connected by a connecting assembly;

[0007] The water tank is fitted with the surface of the servo motor, and a plurality of heat conducting plates are arranged on the water tank, wherein the heat conducting plates are hollow inside and communicate with the water tank;

[0008] The water tank is provided with a heat dissipation component, and the heat dissipation component corresponds to the gap between two adjacent heat conducting sheets;

[0009] The heat dissipation component comprises a rotating shaft, and fan blades are arranged on the rotating shaft, and the rotating shaft is transmission-connected to the output shaft of the servo motor through a transmission component.

[0010] The above-mentioned explosion-proof servo motor is used, and the liquid used for heat conduction is injected into the water tank. The water tank absorbs the heat of the servo motor and conducts the heat to the refrigerant. The refrigerant carries the heat into a plurality of heat conducting plates, and then the wind generated by the heat dissipation component blows to the heat conducting plates, thereby eliminating the heat.

[0011] The power source of the heat dissipation component is the servo motor, which avoids the risk of electric sparks from other electrical appliances. The servo motor itself adopts an explosion-proof design to ensure that the entire device will not generate electric sparks.

[0012] When the servo motor is running, the heat dissipation component is driven to actively dissipate heat. When the servo motor is stopped, no heat is generated, so there is no need for the heat dissipation component to actively dissipate heat. The residual heat generated by the servo motor after operation can be dissipated only through passive heat dissipation formed by the contact between the water tank, heat sink fins and heat conductive sheet and the air.

[0013] Preferably, a plurality of cooling fins are provided on the water tank.

[0014] Preferably, all the heat conducting plates on the water tank are parallel to each other and arranged in layers at equal distances.

[0015] Preferably, a baffle is provided on the heat conducting plate to close the gap between two adjacent heat conducting plates away from the side of the water tank.

[0016] Preferably, the water tank, heat sink fins and heat conducting plates are uniformly made of copper.

[0017] Preferably, silicone grease is applied between the water tank and the servo motor.

[0018] Preferably, the heat dissipation assembly includes a shell, which is arranged between the baffle and the servo motor, and the shell corresponds to all the side surfaces of the heat conducting plate. Two rotating shafts are rotatably arranged in the shell, and fan blades and a pulley are fixed on the rotating shaft. The fan blades are arranged in the shell, and the two pulleys are connected by a belt transmission.

[0019] Preferably, the transmission assembly includes pulley 2 and pulley 3, and pulley 2 and pulley 3 are respectively arranged on the output shaft of the servo motor and any rotating shaft surface on the housing. Pulley 2 and pulley 3 are connected through belt 2 transmission, and the radius of pulley 2 is at least ten times the radius of pulley 3.

[0020] Preferably, the connection assembly comprises two connection bars, which are respectively arranged on the two water tanks and connected by a plurality of screws and nuts.

[0021] The beneficial effects are:

[0022] The heat of the servo motor is absorbed by the water tank and transferred to the refrigerant in the water tank. The refrigerant carries the heat into several heat conducting plates and generates wind through the heat dissipation component to blow to the heat conducting plates, thereby eliminating the heat. The power source of the heat dissipation component is the servo motor to avoid increasing the risk of electric sparks generated by other electrical appliances. When the servo motor is running, the heat dissipation component is driven to actively dissipate heat. When the servo motor is stopped, no heat is generated. The waste heat generated after the servo motor is running can be dissipated only through passive heat dissipation formed by the contact between the water tank, heat dissipation fins and the heat conducting plates and the air. The design of a purely mechanical structure can avoid electric sparks generated by other electrical appliances and reduce costs. The dual combination of active and passive heat dissipation of the device can ensure the efficiency of heat dissipation. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The baffle 4 is used to gather the wind volume, so that the wind of the heat dissipation component 9 can all pass through the gap between the two heat conducting plates 11, thereby avoiding the wind volume and flow rate, and improving the heat dissipation efficiency.

[0039] The water tank 2, the heat sink fins 3 and the heat conducting sheet 11 are uniformly made of copper, which has good thermal conductivity.

[0040] Silicone grease is applied between the water tank 2 and the servo motor 1 to help improve heat conduction.
