Description

Technical Field

[0001] The utility model relates to the technical field of servo motors, and particularly relates to an explosion-proof servo motor. Background Technique

[0002] A servo motor refers to an engine that controls the operation of mechanical components in a servo system. It is an auxiliary motor indirect speed change device. The servo motor can control the speed and position accuracy very accurately. It can convert voltage signals into torque and speed to drive the controlled object. Due to its limited volume, when the servo motor is used for a long time, it will generate heat inside, thus posing a risk of deflagration.

[0003] According to a servo motor with explosion-proof function disclosed on the patent network (authorization announcement number: CN212935646U), it is described that "the utility model relates to the technical field of servo motors, and discloses a servo motor with explosion-proof function, including a housing and a base. The outer surface of the housing is fixedly connected with heat dissipation fins. A heat dissipation cavity is opened in the middle of the housing. Both ends of the heat dissipation cavity are communicated with the inside of the housing. A permanent magnet is arranged in the middle of the housing interior, and a coil is fixedly connected to the inner wall of the housing around the permanent magnet. By setting a first fan on the left side of the housing and opening an air inlet hole on the left side of the first protective cover, the first fan can bring cold air from the outside into the inside of the housing, and then the second fan on the right side of the housing takes out the heat inside the housing. And a heat dissipation cavity is arranged on the housing, so that the heat inside the housing can contact the housing in the heat dissipation cavity, and then the heat is dissipated through the heat dissipation fins. Combining all the above methods, the heat inside the housing can be effectively dissipated."

[0004] Regarding the above description content, the applicant believes that the following problems exist:

[0005] During the use of this utility model, by setting a first fan and opening an air inlet hole on the left side of the first protective cover, the first fan can bring cold air from the outside into the inside of the housing, and then the second fan on the right side of the housing takes out the heat inside the housing. However, in actual use, when the first fan performs the air inlet operation for a long time, dust from the outside will adhere to the surface of the air inlet, thus blocking the air inlet, making it impossible to effectively dissipate the heat inside the motor. If it is not cleaned in time, there is still a risk of deflagration. Therefore, it is necessary to improve an explosion-proof servo motor to solve the above problems. Content of the Utility Model

[0030] Further, the water circulation component 21 includes a water inlet pipe 211, which is fixedly installed on the top of the water tank base 1. A threaded sleeve 212 is installed on the top of the water inlet pipe 211 by threading. A water pump 214 is fixedly installed on the top of the water tank base 1.

A water flow channel 216 is arranged inside the motor housing 213. A drain pipe 217 is fixedly installed on the front of the water flow channel 216 to cool the inside of the motor housing 213 and prevent the motor body 4 from being overheated and damaged.

[0031] Further, the water tank base 1 and the water pump 214 are fixedly installed through a water suction pipe. One end of the outlet pipe 215 away from the water pump 214 is fixedly installed with one end of the water flow channel 216 away from the drain pipe 217, so that the heat inside the motor housing 213 can be absorbed by the water inside the water flow channel 216.

[0032] Further, the cleaning component 22 includes a first protective cover 221, which is fixedly installed on the right side of the motor housing 213. A fixing frame 222 is fixedly installed inside the motor housing 213. A first fan 223 is rotatably installed on the left side of the fixing frame 222. A rotating shaft 224 is fixedly installed on the right side of the first fan 223. A scraping plate 225 is fixedly installed on the right side of the rotating shaft 224. A second protective cover 226 is fixedly installed on the left side of the motor housing 213. A second fan 227 is fixedly installed outside the motor output shaft 5 to clean the dust and sundries on the surface of the first protective cover 221, prevent sundries or dust from blocking the first protective cover 221, and ensure the air intake effect.

[0033] Further, the motor body 4 is fixedly installed inside the motor housing 213. A through hole is opened at the position corresponding to the first protective cover 221 and the rotating shaft 224, and the rotating shaft 224 passes through the through hole and is fixedly installed with the scraping plate 225, so that the scraping plate 225 rotates, quickly cools the water circulated into the inside of the water tank base 1, and ensures that the water circulated inside the water flow channel 216 is all cold water.

[0034] Embodiment 2:

[0035] Please refer to Figure 5 , and in combination with Embodiment 1, it is further obtained that the cooling mechanism 3 includes a first heat conduction block 31, which is fixedly installed inside the water tank base 1. A heat conduction rod 32 is fixedly installed on the front of the first heat conduction block 31. A second heat conduction block 33 is fixedly installed on the front of the heat conduction rod 32. A heat dissipation fan group 34 is fixedly installed on the front of the second heat conduction block 33.

[0036] Further, a through hole is opened at the position corresponding to the water tank base 1 and the heat conduction rod 32, and the heat conduction rod 32 passes through the through hole and is fixedly installed with the second heat conduction block 33, and the heat dissipation fan group 34 is used to cool the second heat conduction block 33.

[0037] During the actual operation process, when this device is in use, water is introduced into the interior of the water tank base 1 through the water inlet pipe 211. The water pump 214 is started, and the water pump 214 pumps out the water inside the water tank base 1 and introduces it into the interior of the motor housing 213 through the water outlet pipe 215. It flows through the motor housing 213 through the water flow groove 216, and a water cooling operation is performed on the interior of the motor housing 213, so that the heat inside the motor housing 213 can be absorbed by the water inside the water flow groove 216, and a cooling operation is performed on the interior of the motor housing 213 to prevent the motor body 4 from overheating and being damaged. When the motor body 4 is started, the motor output shaft 5 drives the second fan 227 to rotate. The rotation of the second fan 227 increases the flow rate inside the motor housing 213, causing the first fan 223 to rotate, sucking in outside air into the interior of the motor housing 213. Moreover, the rotation of the first fan 223 causes the rotating shaft 224 to rotate, and the rotation of the rotating shaft 224 causes the scraping plate 225 to rotate, thereby cleaning the dust and debris on the surface of the first protective cover 221, preventing the debris or dust from blocking the first protective cover 221 and ensuring the air intake effect. And by blowing air outwards through the second fan 227, the cooling effect is increased. After the water inside the water flow groove 216 passes through the drain pipe 217 and is introduced into the interior of the water tank base 1 again, it comes into contact with the first heat conduction block 31. The first heat conduction block 31 transfers the heat to the second heat conduction block 33 through the heat conduction rod 32, and the heat dissipation fan group 34 is used to perform a cooling operation on the second heat conduction block 33, so that the water circulating into the interior of the water tank base 1 is quickly cooled, ensuring that the water circulating inside the water flow groove 216 is all cold water.
