[0002] In the production and application of permanent magnet motor, it is crucial to provide effective protection for the motor. In practical applications, the protective shell of the permanent magnet motor usually requires the following technologies:

[0003] 1. High-strength materials, such as high-strength alloy materials, can withstand external physical impact and pressure.

[0004] 2. Heat dissipation system, such as built-in cooling fins, ventilation holes or liquid cooling channels, to ensure that the heat generated during the operation of the motor can be dissipated in time.

[0005] 3. Sealing measures, such as using high-quality sealing rings, sealing glue, etc., to prevent dust, water vapor, etc. from entering the motor.

[0006] Existing Chinese patent: a permanent magnet synchronous motor shell, patent number: CN204696887U, aims to provide a permanent magnet synchronous motor shell with simple structure and good heat dissipation effect. The technical solution is as follows: a circular ring-shaped shell is used to set the cooling fins, the bottom surface and the top surface of the shell are provided with mounting columns, the left side surface and the right side surface of the shell are provided with mounting holes, characterized in that: the cooling fins include a first cooling fin group horizontally symmetrically arranged on the left side surface of the shell and the right side surface of the shell, and a second cooling fin group vertically symmetrically arranged on the bottom surface of the shell and the top surface of the shell, the first cooling fin group is uniformly arranged and has the same shape, the upper side of the second cooling fin group is flush with the mounting column, and the spacing between the second cooling fin groups gradually increases from the middle position of the mounting column to the mounting column direction, which has good heat dissipation.

[0007] However, in the implementation of the above technical solution, it is found that at least the following technical problems exist: metallurgy, glass manufacturing, ceramic firing, fire fighting equipment, etc. The environmental temperature of their working place is relatively high. The motor needs to run in such a high temperature environment to drive related equipment. The above motor dissipates heat through the cooling fins on the shell. When the motor runs in a high temperature environment, the external high temperature will be conducted to the interior of the motor. The internal resistance of the motor will increase in a high temperature environment, and the permanent magnet will demagnetize in a high temperature environment, which will cause damage to the motor.

[0009] In order to realize above -mentioned purpose, the utility model discloses a technical scheme to realize:

[0012] Preferably, the mounting seat is uniformly provided with a sliding groove for sliding.

[0013] Preferably, the inside of the sliding groove is uniformly slidably installed with a mounting sleeve for fixing.

[0014] Preferably, the mounting seat is uniformly screw-mounted with a threaded column for pushing.

[0015] Preferably, the distal end of the three threaded columns is rotatably installed with a clamping piece for clamping.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] I. When the cooling liquid in the cooling copper pipe flows, it will absorb the heat transferred from the casing, thereby cooling the circuit elements and permanent magnets inside the casing. Since multiple cooling copper pipes are uniformly installed inside the casing, each area of the casing can be cooled simultaneously, and the length of the cooling copper pipe is shortened, reducing the flow time of the cooling liquid inside the cooling copper pipe. This can avoid the cooling liquid from overheating due to too long flow time, affecting the heat dissipation effect. When the motor is used in a high temperature environment, the cooling copper pipe and the ceramic fiber heat insulation sleeve can protect the motor from overheating, avoiding the motor from overheating, achieving the effect of allowing the motor to be used in a high temperature environment.

When installing, the sliding mounting sleeve aligns the mounting sleeve with the mounting hole, and then the motor can be installed in place through the bolt, and then the threaded column is tightened, the threaded column will push the clamping piece to slide towards the mounting sleeve, until the clamping piece abuts against the mounting sleeve, so that the position of the mounting sleeve is limited in a specific position in the sliding groove, and the effect that the motor can be installed in the case of the difference of the mounting hole distance is achieved.

[0029] In view of the problems in the prior art, the utility model provides a permanent magnet motor shell with a protection function, including the shell body 1, the inside of shell body 1 is fixedly installed with the cooling copper pipe 2 for heat dissipation, the side end of shell body 1 is fixedly installed with the backflow communication ring 3 for backflow, the side end of backflow communication ring 3 is fixedly installed with the pump liquid communication ring 4 for liquid sending.

[0030] The two ends of the cooling copper pipe 2 are communicated with the backflow communication ring 3 and the pump liquid communication ring 4 respectively, the outer side wall of the shell body 1 is fixedly installed with the ceramic fiber heat insulation sleeve 5 for heat insulation, the side end of the ceramic fiber heat insulation sleeve 5 is fixedly installed with the mounting seat 6 for mounting, and the mounting seat 6 is uniformly provided with the sliding groove 7 for sliding.

[0031] The inner part of the sliding groove 7 is uniformly slidably installed with a mounting sleeve 8 for fixation, and the mounting seat 6 is uniformly threadedly installed with threaded columns 11 for pushing, and the ends of the three threaded columns 11 are rotatably installed with clamping pieces 9 for clamping.

[0032] The shell 1 is the main body of the motor shell, which contains and protects the internal circuit elements and permanent magnets, and at the same time transmits heat to the cooling copper pipe 2;

[0033] The cooling copper pipe 2: internally flows cooling liquid, absorbs heat from the shell shell 1, and realizes cooling of the internal motor;

[0034] The backflow communication ring 3: simultaneously connects the backflow pipeline of the cooling system and the outlets of multiple cooling copper pipes 2, so that the cooling liquid after absorbing heat in the cooling copper pipe 2 flows back;

[0035] The pump liquid communication ring 4: connects the pump liquid pipeline of the cooling system and the inlets of multiple cooling copper pipes 2, and sends low-temperature cooling liquid into the cooling copper pipe 2;

[0036] The ceramic fiber heat insulation sleeve 5: plays a heat insulation role, prevents external high temperature from invading the internal motor, and avoids the influence of high temperature environment on the cooling liquid in the cooling copper pipe 2;

[0037] The mounting seat 6: for connecting the motor and the position where it needs to be installed;

[0038] The sliding groove 7: provides a sliding track for the mounting sleeve 8;

[0039] The mounting sleeve 8: by aligning with the mounting hole and fixing with bolts, realizes the preliminary installation and positioning of the motor;

[0040] The clamping piece 9: under the pushing of the threaded column 11, tightly abuts against the mounting sleeve 8, limits the position of the mounting sleeve 8, and ensures the stable installation of the motor;

[0041] The threaded column 11: when tightened, pushes the clamping part clamping piece 9 to move.

[0042] Working principle:

[0043] Firstly, during installation, the sliding mounting sleeve 8 aligns the mounting sleeve 8 with the mounting hole, and then the motor can be installed in place through bolts, and then the threaded column 11 is tightened, which will push the clamping piece 9 to slide towards the mounting sleeve 8 until the clamping piece 9 tightly abuts against the mounting sleeve 8, so that the position of the mounting sleeve 8 is limited in a specific position in the sliding groove 7, and then the backflow communication ring 3 is connected with the backflow pipeline of the cooling system, and the pump liquid communication ring 4 is connected with the pump liquid pipeline of the cooling system, and the installation is completed.

When the cooling liquid in the cooling copper pipes 2 flows, the cooling liquid will absorb the heat transferred from the shell 1, thereby cooling the circuit elements and the permanent magnet in the shell 1. Since the plurality of cooling copper pipes 2 are uniformly installed in the shell 1, the cooling copper pipes 2 can simultaneously cool each region of the shell 1, shorten the length of the cooling copper pipes 2, reduce the flow time of the cooling liquid in the cooling copper pipes 2, and avoid the influence of the cooling liquid due to the too long flow time and the high temperature on the heat dissipation effect.
