Description

Technical Field

[0001] The utility model relates to the technical field of shell sealing detection devices, in particular to a shell sealing detection device for a three-phase asynchronous motor. Background Art

[0002] A three-phase asynchronous motor is a type of induction motor that is powered by a 380V three-phase AC current (with a phase difference of 120 degrees). Because the rotor and stator rotating magnetic fields of a three-phase asynchronous motor rotate in the same direction but at different speeds, there is a slip, hence the name. The rotor speed of a three-phase asynchronous motor is lower than the speed of the rotating magnetic field. The rotor winding generates electromotive force and current due to relative motion with the magnetic field, and interacts with the magnetic field to generate electromagnetic torque, achieving energy conversion. After the three-phase asynchronous motor is installed, a housing seal detection device is required to inspect its housing.

[0003] The existing three-phase asynchronous motor housing sealing detection device can only detect whether the housing is sealed when detecting the three-phase asynchronous motor housing, but cannot clearly observe the position where the sealing is not complete, and requires subsequent re-inspection, which is relatively inconvenient. Therefore, we propose a three-phase asynchronous motor housing sealing detection device. Utility Model Content

The existing three-phase asynchronous motor housing sealing detection device can only detect whether the housing is sealed when detecting the three-phase asynchronous motor housing, and cannot clearly observe the position where the sealing is not complete, and needs to be checked again later, which is inconvenient.

[0011] As a preferred solution of the present invention, a bearing base is fixed to the bottom of the device body, and a control panel is installed on the right side of the device body.

[0012] The technical effect of adopting the above further solution is that the device body can be supported by the design of the bearing base.

[0013] As a preferred solution of the present invention, a drainage groove is provided between the inner bottom surface of the detection tank and the water storage cylinder. A water pump is installed inside the water storage cylinder, and the output end of the water pump is connected to the drainage groove.

[0014] The technical effect of adopting the above further solution is: by connecting the output end of the water pump with the drainage trough, the water pump can well pump the water inside the detection tank into the water storage cylinder through the drainage trough.

[0015] As a preferred solution of the present invention, a second electric valve is installed on the inner wall of the drainage groove corresponding to the detection groove.

[0016] The technical effect of adopting the above further solution is that the design of the second electric valve can well seal the drainage groove to prevent it from affecting the sealing effect inside the detection groove.

[0017] As a preferred solution of the present invention, a water inlet is provided at the top of the water storage cylinder, and the water inlet is communicated with the interior of the water storage cylinder.

[0018] The technical effect of adopting the above further solution is: the water injection port is connected to the interior of the water storage cylinder, so that the staff can add water to the interior of the water storage cylinder through the water injection port.

[0019] As a preferred solution of the present invention, the air pipe is connected to the interior of the detection tank, and the air pipe is connected to the input end of the air pump.

[0020] The technical effect of adopting the above further solution is: the air pipe is connected to the inside of the detection tank and the air pipe is connected to the air pump, so that the air pump can very conveniently extract the air inside the detection tank or fill the air into the detection tank through the air pipe.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0032] Example 1

[0033] like Figure 1-4 As shown, the utility model provides a technical solution: a three-phase asynchronous motor housing seal detection device, including a device body 1, a detection groove 101 is opened inside the device body 1, and an air pressure detector is installed on the inner side wall of the detection groove 101 near the top. A plurality of underwater cameras 102 are evenly installed on the inner side wall of the detection groove 101. The underwater cameras 102 can record underwater. A water storage cylinder 2 is installed on the top of the device body 1. The water storage cylinder 2 can store water. The bottom of the water storage cylinder 2 corresponds to the device body 1 and passes through the device body 1. A water supply trough 201 is provided, through which the water inside the water storage cylinder 2 can enter the detection tank 101. A first electric valve 103 is installed on the inner wall of the detection tank 101 corresponding to the water supply trough 201. The first electric valve 103 can seal the water supply trough 201. An air pump 3 is installed on the left side of the device body 1. The input end of the air pump 3 extends to the inner wall of the detection tank 101 and is connected to an air pipe 301. The air pump 3 can draw air into the detection tank 101 or fill external air into the interior of the detection tank 101 through the air pipe 301.

[0034] Example 2

[0035] like Figure 1-4As shown, a placement opening 104 is opened on the front of the device body 1, and an electric sealing door 105 is installed on the inner wall of the placement opening 104. The electric sealing door 105 is adapted to the placement opening 104. By adapting the electric sealing door 105 to the placement opening 104, the detection slot 101 can be formed into a sealed state after the electric sealing door 105 is closed.

[0036] A placement rack 106 is installed on the inner wall of the detection tank 101, and the underwater camera 102 is facing the placement rack 106 during installation. The design of the placement rack 106 allows the staff to place the three-phase asynchronous motor well, and by facing the placement rack 106 during installation, the underwater camera 102 can better observe the three-phase asynchronous motor.

[0037] A supporting base 107 is fixed to the bottom of the device body 1 , and a control panel 108 is installed on the right side of the device body 1 . The design of the supporting base 107 can support the device body 1 .

[0038] A drainage groove 202 is provided between the inner bottom surface of the detection tank 101 and the water storage cylinder 2. A water pump 203 is installed inside the water storage cylinder 2. The output end of the water pump 203 is connected to the drainage groove 202. By connecting the output end of the water pump 203 to the drainage groove 202, the water pump 203 can well extract the water inside the detection tank 101 to the inside of the water storage cylinder 2 through the drainage groove 202.

[0039] A second electric valve 204 is installed on the inner wall of the drainage groove 202 corresponding to the detection groove 101. The design of the second electric valve 204 can well seal the drainage groove 202 to prevent it from affecting the sealing effect inside the detection groove 101.

[0040] A water inlet 205 is provided at the top of the water storage cylinder 2, and the water inlet 205 is connected to the interior of the water storage cylinder 2. The water inlet 205 is connected to the interior of the water storage cylinder 2, so that the staff can add water to the interior of the water storage cylinder 2 through the water inlet 205.

[0041] The air pipe 301 is connected to the interior of the detection tank 101, and the air pipe 301 is connected to the air pump 3. Through the connection between the air pipe 301 and the interior of the detection tank 101 and the connection between the air pipe 301 and the air pump 3, the air pump 3 can very conveniently extract the air inside the detection tank 101 or fill the air into the detection tank 101 through the air pipe 301.

[0042] The working process of the present invention is as follows: when a three-phase asynchronous motor housing seal detection device is used to detect that the three-phase asynchronous motor housing has a leak, the staff can first open the first electric valve 103. After the first electric valve 103 is opened, the water inside the water storage cylinder 2 can be sent into the detection tank 101 through the water feeding tank 201. At this time, the staff can clearly observe the water level inside the detection tank 101 through the underwater camera 102. After the water level is a distance above the three-phase asynchronous motor housing, the air pump 3 is turned on and the air inside the detection tank 101 is extracted through the air pipe 301, so that the air inside the three-phase asynchronous motor housing can be better discharged through the leak. While the air is being discharged, the underwater camera 102 can record from various angles, so that the position where the three-phase asynchronous motor housing is not completely sealed can be well known. Compared with the existing three-phase asynchronous motor housing seal detection device, when a leak has been detected in the three-phase asynchronous motor housing, the unsealed leak can be well detected, thereby reducing the subsequent operation steps and being more convenient during maintenance.

[0043] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
