Description

Technical Field

[0001] This invention relates to the field of water-cooled motor technology, specifically a water-cooled motor cooling structure that prevents dirt buildup. Background Technology

[0002] With the rapid development of industrial automation and electrification technologies, water-cooled motors are widely used in new energy vehicles, CNC machine tools, industrial robots, and aerospace due to their advantages such as high heat dissipation efficiency and stable operation. Water-cooled motors typically use cooling water channels in their casing or stator core to carry away the heat generated during motor operation through circulating coolant, thus maintaining the motor within a safe operating temperature range.

[0003] However, most commonly used water-cooled motors employ a one-piece cast or welded closed water channel structure. During long-term circulating cooling, impurities, scale, or metal debris in the cooling water easily accumulate in dead corners or areas with low flow rates. Because the water channel is a closed structure, these deposits are difficult to clean and remove. Long-term accumulation not only reduces heat transfer efficiency but can also cause local blockages in the water channel, affecting the cooling effect and, in severe cases, even leading to motor overheating and burnout. Furthermore, when the internal water channel becomes blocked or damaged, complex and expensive repairs are often required for the entire motor, or even its complete scrapping. Simultaneously, the cooling water lacks filtration when entering the motor. Although the cooling water is pre-filtered, particulate matter gradually forms inside after long-term use. If not filtered, this leads to blockage of the internal water channel of the water-cooled motor and the formation of scale. Summary of the Invention

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 , Figure 3 , Figure 4 and Figure 8As shown, the water-cooled motor cooling structure for preventing dirt deposition according to the present invention includes a motor body 1, a plurality of cooling mechanisms 2 for heat dissipation are installed on the outside of the motor body 1, a mounting mechanism 3 for fixing the cooling mechanism 2 is installed on the top of the motor body 1, and a filter mechanism 4 for filtering impurities and preventing dirt deposition is installed on the mounting mechanism 3.

[0025] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the cooling mechanism 2 includes a water storage tank 201. Multiple water storage tanks 201 arranged in a ring are installed on the outside of the motor body 1. The water storage tank 201 has a water storage chamber 202 inside. A partition 203 is fixedly connected to the center line inside the water storage tank 201. The top of the partition 203 is connected to the top of the water storage tank 201, and the bottom of the partition 203 is a certain distance from the bottom of the water storage tank 201. After the multiple water storage tanks 201 are filled with coolant, they dissipate heat to the outside of the motor body 1. The partition 203 divides the top of the water storage chamber 202 inside the water storage tank 201 into two halves, forming a "U" shaped structure, which allows the cooling water to flow fully inside the water storage chamber 202, increasing the heat dissipation effect.

[0026] Specifically, such as Figure 3 As shown, the water storage tank 201 has an arc-shaped structure. The top of the water storage tank 201 is provided with an inlet 205 and an outlet 206. The bottom of the water storage tank 201 is detachably connected to a base 204 by fasteners. The arc-shaped structure of the water storage tank 201 allows multiple water storage tanks 201 to completely wrap around the outside of the motor body 1, achieving good heat dissipation. At the same time, the opening of the inlet 205 and the outlet 206 facilitates the entry and exit of cooling water, thereby removing heat from the motor body 1. The detachable installation of the base 204 facilitates the cleaning and maintenance of the inside of the water storage tank 201, making the operation convenient.

[0027] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the installation mechanism 3 includes a first slot 302. The first slot 302 is provided on the outer side of the bottom of the motor body 1. The bottom edges of multiple water storage tanks 201 are respectively engaged with the inside of the first slot 302. A fixing sleeve 301 is slidably connected to the top of the motor body 1. A second slot 306 is provided on the inner side of the bottom of the fixing sleeve 301. The second slot 306 is engaged with the top edges of the multiple water storage tanks 201. The opening of the first slot 302 facilitates the insertion and engagement of the bottom of the multiple water storage tanks 201, so that the water storage tanks 201 will not fall off the outer side of the bottom of the motor body 1. With the fixing sleeve 301 engaging with the outer side of the top of the motor body 1 and with the cooperation of the second slot 306, the fixing sleeve 301 engages with the top of the multiple water storage tanks 201, so that the water storage tanks 201 are stably installed on the outside of the motor body 1.

[0028] Specifically, such as Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the outer side of the motor body 1 is provided with multiple equidistant protrusions 304, and the side walls of multiple water tanks 201 are respectively provided with first positioning grooves 303. The first positioning grooves 303 are engaged with the protrusions 304. The inner side wall of the fixing sleeve 301 is provided with multiple second positioning grooves 305. The multiple second positioning grooves 305 slide with the outer side of the multiple protrusions 304 respectively. With the setting of the protrusions 304, after the water tank 201 is attached to the outer side of the motor body 1, the first positioning grooves 303 are engaged with the protrusions 304, which plays a role in positioning the water tank 201. The water tank 201 will not rotate on the outer side of the motor body 1. With the opening of the second positioning grooves 305, the fixing sleeve 301 is able to play a positioning role on the top outer side of the motor body 1. The fixing sleeve 301 will not rotate at will, but can only slide up and down to be disassembled.

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the filter mechanism 4 includes a connecting groove 405. Two connecting grooves 405 are provided at the top edge of the fixed sleeve 301. Connecting seats 403 are threadedly connected to the two connecting grooves 405 respectively. A filter screen 404 is threadedly connected to the bottom of the connecting seat 403. A water inlet pipe 401 is connected to one of the connecting seats 403, and a water outlet pipe 402 is connected to the other connecting seat 403. The opening of the connecting groove 405 facilitates the connection of the connecting seat 403. The installation of the water inlet pipe 401 and the water outlet pipe 402 facilitates the introduction of external cooling water into the fixed sleeve 301, realizing the distribution of cooling water to the internal circulation of multiple water storage tanks 201 to achieve heat dissipation. The filter screen 404 installed at the bottom of the connecting seat 403 facilitates the filtration of impurities in the cooling water, reducing the pollution inside the water storage tank 201.

[0030] Specifically, such as Figure 6 and Figure 7 As shown, the fixed sleeve 301 is equipped with a conveying mechanism 8 for supplying cooling water to multiple cooling mechanisms 2. The conveying mechanism 8 includes a first collecting groove 803. The fixed sleeve 301 has a first collecting groove 803 at its top and a second collecting groove 804 at its bottom. The bottoms of two connecting grooves 405 are respectively connected to the first collecting groove 803 and the second collecting groove 804. Multiple first connecting pipes 801 and second connecting pipes 802 are vertically connected to the bottom of the fixed sleeve 301. The tops of the multiple first connecting pipes 801 are respectively connected to the first collecting groove 803 through guide grooves 805, and the multiple second connecting pipes 802 are respectively connected to the second collecting groove 804 through guide grooves 805. The bottoms of the first connecting pipes 801 are connected to the inlet 205 at the top of the water storage tank 201, and the bottoms of the second connecting pipes 802 are connected to the top of the water storage tank 201. The outlet 206 is connected, and the opening of the first collection tank 803 facilitates the storage and collection of the delivered cooling water. Then, it is transported to the interior of multiple water storage tanks 201 through multiple guide channels 805 and multiple first connecting pipes 801 to dissipate heat from the motor body 1. After absorbing the heat from the motor body 1, the cooling water flows to the outlet 206 through the bottom of the partition 203, and is then transported to the interior of the second collection tank 804 through multiple second connecting pipes 802 in conjunction with the guide channels 805. Finally, it is discharged and recycled through the connecting channel 405 and the outlet pipe 402, thereby realizing the cooling water circulation operation. This facilitates the removal of heat from the outside of the motor body 1 and achieves the cooling operation of the motor body 1. The independent heat dissipation of multiple water storage tanks 201 reduces internal blockage and increases the heat dissipation effect. When one of them is damaged, it can be disassembled and replaced at any time, making maintenance more convenient.

[0031] Specifically, such as Figure 7 As shown, both the first collecting trough 803 and the second collecting trough 804 are annular structures. The outer diameter of the first collecting trough 803 is smaller than the inner diameter of the second collecting trough 804. The first collecting trough 803 is located above the second collecting trough 804. The annular structure design of the first collecting trough 803 and the second collecting trough 804 facilitates the centralized transportation and discharge of cooling water. At the same time, by setting collecting troughs of different diameters, the two collecting troughs can operate independently without interference, allowing the first connecting pipe 801 and the second connecting pipe 802 to work independently.

[0032] Specifically, such as Figure 4 , Figure 5 , Figure 9 and Figure 10As shown, a limiting mechanism 5 for limiting the movement between the fixing sleeve 301 and the motor body 1 is installed on the inner side of the top of the motor body 1. The limiting mechanism 5 includes a limiting groove 502. The inner wall of the fixing sleeve 301 is provided with two sets of symmetrically distributed limiting grooves 502. Two sets of symmetrically distributed limiting rods 501 are installed on the inner side of the top of the motor body 1. One end of each of the two sets of limiting rods 501 slides elastically with the inside of the motor body 1 through a contact spring 503. The other end of each of the two sets of limiting rods 501 extends to the outside of the motor body 1 and abuts against the inside of the limiting groove 502. The limiting groove 502 and the end of the limiting rod 501 are both hemispherical structures. The exposed length of the limiting rod 501 is half of the outer diameter of the limiting rod 501. With the installation of the limiting rod 501, the limiting rod 501 can slide elastically on the inner side of the top of the motor body 1 under the cooperation of the contact spring 503. Under the contact of the contact spring 503, the limiting rod 501 extends to the outside of the motor body 1 and is fixed. When the sleeve 301 is fitted onto the outer side of the motor body 1, the bottom of the fixed sleeve 301 abuts against the two sets of limiting rods 501. Since the exposed end of the limiting rod 501 is a hemispherical structure, the fixed sleeve 301 abuts against the limiting rod 501, releasing the elastic contraction of the abutment spring 503, allowing the fixed sleeve 301 to slide down and engage with the tops of the multiple water tanks 201. After the fixed sleeve 301 slides into place, the end of the limiting rod 501 aligns with the limiting groove 502. At this time, the abutment spring 503... Under the resistance, the limiting rod 501 resets and inserts into the limiting groove 502 to limit the fixed sleeve 301, so that the fixed sleeve 301 is installed stably on the outside of the motor body 1. When the fixed sleeve 301 is pulled by a certain pulling force, since the limiting groove 502 is also a hemispherical structure, the limiting groove 502 will spherically abut against the end of the limiting rod 501, causing the limiting rod 501 to retract. At this time, it is convenient to pull out and disassemble the fixed sleeve 301, and convenient to replace the faulty water tank 201.

[0033] Specifically, such as Figure 10 As shown, each of the two sets of limiting rods 501 has a guide rod 504 installed at one end. The guide rod 504 passes through the contact spring 503 and slides inside the motor body 1. The limiting rod 501 has a "convex" shaped structure. The installation of the guide rod 504 facilitates the guiding function when the limiting rod 501 slides, and also facilitates the subsequent locking of the limiting rod 501. The "convex" shaped structure design of the limiting rod 501 helps to limit the length of the exposed end of the limiting rod 501, and facilitates the smooth engagement and disengagement of the limiting rod 501 and the limiting groove 502.

[0034] Specifically, such as Figure 2 , Figure 4 , Figure 9 and Figure 10As shown, a locking mechanism 6 for locking control of the limit mechanism 5 is installed on the top of the motor body 1. The locking mechanism 6 includes baffles 602. Two baffles 602 are slidably connected to the inner side of the top of the motor body 1. A return spring 604 is connected between the bottom of the two baffles 602 and the inside of the motor body 1. The top of the baffles 602 extends to the outer side of the top of the motor body 1. One end of two sets of guide rods 504 abuts against the outer side of the two baffles 602 respectively. Two grooves 603 are provided on the back side of the two baffles 602 respectively. The two sets of guide rods 504 are located at the top of the two sets of grooves 603 respectively. A terminal block 7 is installed at the center of the top of the motor body 1. A pressure plate 601 for driving control of the two baffles 602 is slidably connected to the terminal block 7. The two ends of the pressure plate 601 are respectively connected to the two baffles 602. 02 Top connection, under the elastic force of the return spring 604, the two baffles 602 rise to the return state. The grooves 603 on the two baffles 602 are aligned with the two sets of guide rods 504 respectively, so that the limit rod 501 has room to slide, realizing the installation and removal of the fixing sleeve 301. After the external aviation plug is inserted into the terminal block 7 on the top of the motor body 1, the pressure plate 601 will be squeezed down. The pressure plate 601 drives the two baffles 602 to get rid of the elastic force of the return spring 604 and slide down to a certain position, so that the baffles 602 block the guide rod 504, so that the limit rod 501 cannot slide, which is conducive to locking the limit rod 501, making the fixing sleeve 301 stable and unremovable on the outside of the motor body 1, ensuring the normal operation of the motor body 1 and multiple water tanks 201.

[0035] When the present invention is in use, it is first installed through a plurality of annularly distributed water storage tanks 201. After cooling liquid is filled into the plurality of water storage tanks 201, the plurality of water storage tanks 201 dissipate heat from the outer side of the motor body 1. The arrangement of the partition plate 203 facilitates dividing the top of the water storage chamber 202 inside the water storage tank 201 into two halves to form a "U"-shaped structure, which enables the cooling water to fully flow inside the water storage chamber 202 and improves the heat dissipation effect. The design of the arc-shaped structure of the water storage tank 201 facilitates the plurality of water storage tanks 201 to completely wrap the outer side of the motor body 1, so as to achieve excellent heat dissipation. Meanwhile, the arrangement of the water inlet 205 and the water outlet 206 facilitates the entry and discharge of the cooling water, so that the heat of the motor body 1 can be carried away. The detachable installation of the base 204 facilitates cleaning and maintenance of the interior of the water storage tank 201, which is easy to operate. The arrangement of the first clamping groove 302 facilitates inserting and clamping the bottoms of the plurality of water storage tanks 201, so that the water storage tanks 201 will not fall off from the outer side of the bottom of the motor body 1. The fixing sleeve 301 is sleeved on the outer side of the top of the motor body 1, and under the cooperation of the second clamping groove 306, the fixing sleeve 301 clamps the tops of the plurality of water storage tanks 201, so as to realize stable installation of the water storage tanks 201 on the outer side of the motor body 1. Through the arrangement of the protruding strip 304, after the water storage tank 201 is attached to the outer side of the motor body 1, the first positioning groove 303 is buckled with the protruding strip 304, which plays a positioning role for the water storage tank 201, so that the water storage tank 201 will not rotate on the outer side of the motor body 1. The arrangement of the second positioning groove 305 facilitates the positioning of the fixing sleeve 301 on the outer side of the top of the motor body 1, so that the fixing sleeve 301 will not rotate arbitrarily and can only be disassembled and assembled by sliding up and down. Through the installation of the limiting rod 501, under the cooperation of the abutting spring 503, the limiting rod 501 can elastically slide inside the top of the motor body 1. Under the abutting of the abutting spring 503, the limiting rod 501 extends to the outer side of the motor body 1. When the fixing sleeve 301 is sleeved and installed on the outer side of the motor body 1, the bottom of the fixing sleeve 301 abuts against the two sets of limiting rods 501. Since the exposed end of the limiting rod 501 is a hemispherical structure, the fixing sleeve 301 abuts against the limiting rod 501 to overcome the elastic force of the abutting spring 503 and contract, which facilitates the fixing sleeve 301 to slide down to clamp the tops of the plurality of water storage tanks 201. After the fixing sleeve 301 slides down to the proper position, the end of the limiting rod 501 is aligned with the limiting groove 502. At this time, under the abutting of the abutting spring 503, the limiting rod 501 resets and is inserted into the limiting groove 502, so as to realize the limiting of the fixing sleeve 301, so that the fixing sleeve 301 is stably installed on the outer side of the motor body 1. When the fixing sleeve 301 is pulled with a certain pulling force, since the limiting groove 502 is also a hemispherical structure, the limiting groove 502 will abut against the spherical end of the limiting rod 501 to make the limiting rod 501 contract. At this time, it is convenient to pull out and disassemble the fixing sleeve 301, which facilitates replacing the problematic water storage tank 201. Through the installation of the guide rod 504, it plays a guiding role when the limiting rod 501 slides, and at the same time facilitates subsequent limiting and locking of the limiting rod 501. Through the design of the "convex"-shaped structure of the limiting rod 501,This design helps to limit the length of the exposed end of the limiting rod 501, facilitating smooth engagement and disengagement between the limiting rod 501 and the limiting groove 502. Under the elastic force of the return spring 604, the two baffles 602 rise to the reset state. The grooves 603 on the two baffles 602 are aligned with the two sets of guide rods 504, allowing the limiting rod 501 to have sliding space, thus enabling the assembly and disassembly of the fixing sleeve 301. After connecting the external aviation plug to the terminal block 7 on the top of the motor body 1, the pressure plate 601 will be squeezed down. The pressure plate 601 drives the two baffles 602 to slide down a certain position, freeing them from the elastic force of the return spring 604. The baffle 602 blocks the guide rod 504, preventing the limit rod 501 from sliding and facilitating a locking mechanism. This ensures the fixed sleeve 301 is stably and removably mounted on the outside of the motor body 1, guaranteeing the normal operation of the motor body 1 and multiple water tanks 201. The connecting groove 405 facilitates the connection to the connecting seat 403. The installation of the inlet pipe 401 and outlet pipe 402 allows external cooling water to be introduced into the fixed sleeve 301, enabling the cooling water to circulate within the multiple water tanks 201 for heat dissipation. A filter screen 404 is installed at the bottom of the connecting seat 403. The design facilitates the filtration of impurities in the cooling water, reducing contamination inside the water storage tank 201. The first collecting trough 803 facilitates the storage and collection of the transported cooling water. The water is then transported to multiple water storage tanks 201 via multiple guide troughs 805 and multiple first connecting pipes 801, thus dissipating heat from the motor body 1. After absorbing heat from the motor body 1, the cooling water flows through the bottom of the partition 203 to the outlet 206, and then through multiple second connecting pipes 802 in conjunction with the guide troughs 805 to the second collecting trough 804 for collection. Finally, it is discharged and recycled through the connecting trough 405 and the outlet pipe 402, thereby achieving… The cooling water circulation system effectively removes heat from the outside of the motor body 1, achieving heat dissipation. Multiple water tanks 201 provide independent cooling, reducing internal blockages and increasing heat dissipation efficiency. Damaged tanks can be easily disassembled and replaced, making maintenance more convenient. The annular structure design of the first collecting trough 803 and the second collecting trough 804 facilitates centralized delivery and discharge of cooling water. Furthermore, by using collecting troughs of different diameters, the two collecting troughs can operate independently without interference, allowing the first connecting pipe 801 and the second connecting pipe 802 to function independently.
