Description

Technical Field

[0001] This invention belongs to the field of engine cylinder head locking plate processing machinery application technology, specifically an overheat protection device for a water pump. Background Technology

[0002] A water pump is a device used to pump water and can continuously create a vacuum or negative pressure at the inlet. The working medium can be gas or liquid. It is a small instrument and is widely used in many fields such as water treatment, liquid sampling, scientific research, instrumentation, chemical analysis, medical care and environmental protection. However, when pumping water in a large area of ​​shallow water, the water cannot completely cover the pump to allow it to cool down. If the pump does not get cooled after long-term high-power operation, the motor may burn out.

[0003] Chinese patent CN212106234U discloses a device for cooling a water pump that pumps water in shallow water, which is suitable for pumping operations in large areas of shallow water or stagnant water. It solves the problem that the water pump cannot effectively cool down when pumping water in shallow water. Based on economy, safety and practicality, it increases the service life of the water pump, saves costs and generates good social and economic benefits.

[0004] However, although the above-mentioned device can use a water pump to pump water from the shallows and direct the pumped water to the top of the pump body, and then spray the pump body through the nozzles on the top, this method of directly introducing natural water and spraying water for cooling not only fails to filter the pumped natural water source, causing impurities in the water source to impact the pump body or cause the pump body to be jammed by particles, thus affecting the service life of the pump body, but also causes water to fall from the top of the pump body and impact the top surface of the pump body, causing water to splash in all directions. This not only makes it difficult to cool parts other than the top of the pump body, forming heat dissipation dead zones, but also causes continuous inefficient water spraying, which easily leads to energy consumption and reduces the cooling efficiency of the pump body. Summary of the Invention

[0005] The purpose of this invention is to separate water from impurities by setting up a water inlet component, thereby reducing the damage to the pump body caused by particulate matter or the pump body stopping due to particulate matter jamming when the external water source is used for cooling; furthermore, by setting up a water distribution component, multi-directional spraying cooling is achieved on the outer surface of the pump body; finally, the water distribution component and the component work together to achieve multiple sets of nozzles rotating around the pump body, forcing the water source to spray the pump body evenly, thereby further improving the cooling effect. At the same time, intermittent water spraying is achieved to reduce energy consumption caused by continuous water spraying and improve cooling efficiency.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] An overheat protection device for a water pump includes a pump body, an inlet, and a drain pipe. The inlet is located at the bottom of the pump body, and the drain pipe is located near the lower end of the right side of the pump body. The drain pipe has a concave structure, and a branch pipe is installed at the center of the right side of the drain pipe. An outer sleeve is located at the top of the pump body and is fitted onto the outside of the pump body. The length of the outer sleeve is three-quarters of the length of the pump body, and the inner diameter of the outer sleeve is larger than the diameter of the pump body. Several sets of toothed blocks are arranged circumferentially in the middle section of the inner wall of the outer sleeve. A cooling mechanism is provided between the upper inner wall of the outer sleeve and the top of the pump body, and the cooling mechanism includes an inlet component and a water distribution component.

[0008] The water inlet assembly includes a water purification cylinder, the cylinder of which is composed of an upper top cylinder and a lower top cylinder, which are rotatably connected. The upper end of the drain pipe extends into the upper top cylinder near the right side. A circular hollow turntable is located near the center inside the upper top cylinder. A rotating rod is fixedly connected between the center of the front end of the hollow turntable and the inner wall of the front end of the upper top cylinder. The rotating rod extends to the front end of the upper top cylinder and is fixedly connected to a motor. A transmission wheel is located on the outside of the rotating rod near the end of the hollow turntable. The hollow turntable is open at the lower half of the left side and the upper half of the right side. A material distribution plate is rotatably connected inside the hollow turntable. The material distribution plate is hollow and its diameter is the same as the inner diameter of the hollow turntable. A material collection frame is provided on the right side of the upper top cylinder near the lower end. The material collection frame has a frame opening on the left side. A guide mesh plate is hinged inside the frame opening. The guide mesh plate is inclined with the left side higher than the right side. The left two-thirds of the plate extends into the upper top cylinder and is located at the lower right side of the hollow turntable.

[0009] A leaf-shaped abutment is provided on the lower left side of the guide mesh plate, and a rotating rod 2 is connected through the inside of the leaf-shaped abutment. The rear end of the rotating rod 2 is rotatably connected to the inner wall of the rear end of the upper top cylinder, and a transmission wheel 2 is fixedly installed at its front end. The transmission wheel 2 is connected to the transmission wheel 1 by belt drive.

[0010] Furthermore, drain pipes two are fixedly installed at equal intervals on the outer surface of the lower top cylinder, and drain pipes two are arranged in an L-shape and extend to the lower end of the lower top cylinder. Several sets of toothed grooves are arranged at equal intervals on the inner wall of the lower top cylinder near the upper cylinder opening. A rotating rod three is rotatably connected to the center of the inner wall of the front end of the lower top cylinder near the upper end. The rod three extends to the center of the lower top cylinder and is fixedly connected to a redirecting gear. A transmission wheel two is fixedly installed at the middle end of the rotating rod three. Both sets of transmission wheels two are connected to transmission wheel one by belt drive.

[0011] Furthermore, a rotating shaft is rotatably connected to the center of the lower top cylinder, and several sets of blades are fixedly installed at equal intervals on the outside of the rotating shaft. A gear disk one is fixedly installed at the top of the rotating shaft. The gear disk one meshes with a reversing gear, and a gear disk two is meshed at the right side of the gear disk one at the opening of the lower top cylinder. The other end of the gear disk two meshes with a tooth groove.

[0012] Furthermore, the water distribution component includes a pentagonal frame strip, which is fitted onto the outside of the pump body. A circular groove is provided at the top corner of each pentagonal frame strip, and a fan-shaped clamping frame is provided at the bottom of each set of circular grooves at the lower end of the groove.

[0013] Furthermore, a disc is rotatably connected inside the clamping frame, and a bearing is fixedly installed at the center of the bottom of the disc. The lower end of the bearing passes through the clamping frame and is fixedly connected to a gear disc three. The gear disc three meshes with a toothed block. A water collection groove is opened inside the disc. The bottom opening of the drain pipe two passes through the circular groove and is rotatably connected to the top of the disc. The water collection groove is connected to the drain pipe two.

[0014] Furthermore, the radius of the disc is smaller than the radius of the clamping frame, and an arc-shaped abutment is hinged to the side of the disc near the inside of the clamping frame. A push plug is hinged to the inner ring surface of the other end of the arc-shaped abutment, and the push plug extends into the water collection tank. A nozzle is provided inside the water collection tank at the opposite end of the push plug, and the nozzle is close to the outer surface of the pump body.

[0015] The specific usage method of this overheat protection device includes the following steps:

[0016] Step 1: Start the pump body and draw water from the shallow area into the pump body through the inlet. Then, it is transmitted through the drain pipe. Part of the water is discharged to the outside through the branch pipe, while the other part of the water is filtered through the water inlet component. The filtered water is then sprayed onto the surface of the pump body for physical cooling.

[0017] Step 2: When the water inlet assembly is running, the water source is delivered to the distribution plate through the drain pipe 1 and the upper opening of the hollow turntable. After being filtered by the mesh of the distribution plate, the impurities in the water source are filtered at the upper notch of the upper opening of the hollow turntable. The water source falls through the hollow hole and is discharged through the opening at the lower left end of the distribution plate and falls into the lower top cylinder. Then it is discharged outward through the drain pipe 2. The motor is started at the same time, which drives the rotating rod 1, the transmission wheel 1 and the hollow turntable to rotate. As the hollow turntable rotates downward, it is convenient to scrape the impurity particles that remain at the upper opening and let them fall down to the surface of the guide mesh plate. Then, it slides down the inclined surface of the plate into the collection frame. This achieves the separation of water and impurities, reducing the possibility of damage to the particulate matter pump body when the external water source cools down or the pump body stopping due to particulate matter jamming.

[0018] Furthermore, the guide screen can also filter splashed water and water mixed with impurities. At the same time, the belt drives two sets of transmission wheels to rotate, which in turn forces the rotating rods to rotate. When the rotating rod rotates, it drives the blade-shaped abutment to rotate and intermittently presses against the left end of the guide screen, causing it to tilt upwards. This not only accelerates the discharge rate of impurity particles from the surface of the guide screen, but also reduces the likelihood of impurity particles getting stuck on the surface of the guide screen due to the impact between the guide screen and the blade-shaped abutment, thus improving the screening efficiency.

[0019] Step 3: When the rotating rod 3 rotates, the reversing gear meshes with the gear disc 1, thereby driving the rotating shaft and blades to rotate. The gear disc 1 meshes with the gear disc 2, thereby driving the lower top cylinder to rotate in the opposite direction, which is opposite to the rotation direction of the blades and the upper top cylinder, thus accelerating the discharge rate of water in the lower top cylinder.

[0020] Step 4: Filtered water is sent to the water collection tank of the disc through multiple sets of drain pipes, and then sprayed onto the outer surface of the pump body through the nozzles. The lower top cylinder drives the water distribution component to rotate through the second drain pipe. In this way, multiple sets of nozzles rotate around the pump body to achieve uniform spraying of water to the pump body and improve the cooling effect. When the pentagonal frame bar rotates, the toothed disc engages with the toothed block, forcing the bearing and the disc to rotate inside the clamping frame. When the arc-shaped abutment rotates into the clamping frame, the arc-shaped abutment presses against the inner wall of the clamping frame, forcing the push plug to press into the water collection tank. This achieves water spraying from the nozzles onto the pump body surface for cooling. When the arc-shaped abutment rotates to the outside of the clamping frame, under the action of the hinge force, the arc-shaped abutment returns to its original position and pulls the push plug outward. At this time, the nozzle stops spraying outward, achieving intermittent water spraying to reduce energy consumption caused by continuous water spraying.

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

[0022] 1. In use, this invention, by setting up a water inlet component, delivers water to the distribution plate through a drain pipe and the upper opening of the hollow turntable. After being filtered by the mesh of the distribution plate, impurities in the water are filtered at the upper notch of the upper opening of the hollow turntable. The water then falls through the hollow holes and is discharged through the lower left opening of the distribution plate into the lower top cylinder. Finally, it is discharged outward through a drain pipe. Simultaneously, the motor is started, which drives the rotating rod, transmission wheel, and hollow turntable to rotate. As the hollow turntable rotates downward, it facilitates scraping the impurity particles remaining at the upper opening and letting them fall downward onto the surface of the guide mesh plate. Then, it slides down the inclined surface of the plate into the collection frame, thereby achieving the separation of water and impurities. This reduces the possibility of damage to the particulate matter pump body due to external water cooling or the pump body stopping due to particulate matter jamming.

[0023] 2. In use, this invention, by setting up a water distribution component, filters the water and sends it to the water collection tank of the disc through multiple sets of drain pipes. Then, it is sprayed onto the outer surface of the pump body through nozzles, achieving multi-directional spraying and cooling of the outer surface of the pump body. The water distribution component works in conjunction with other components. The top cylinder drives the water distribution component to rotate through the second drain pipe. This allows multiple sets of nozzles to rotate around the pump body, achieving uniform spraying of water onto the pump body and improving the cooling effect. When the pentagonal frame rotates, the third gear plate meshes with the toothed block, forcing the bearing and the disc to rotate inside the clamping frame. When the arc-shaped abutment plate rotates into the clamping frame, it presses against the inner wall of the clamping frame, forcing the push plug to press into the water collection tank. This achieves spraying water onto the pump body surface for cooling. When the arc-shaped abutment plate rotates to the outside of the clamping frame, under the action of hinge force, the arc-shaped abutment plate resets and pulls the push plug outward. At this time, the nozzle stops spraying outward, achieving intermittent water spraying to reduce energy consumption caused by continuous water spraying. Attached Figure Description

[0035] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figure 1-9 As shown, an overheat protection device for a water pump includes a pump body 1, an inlet 2, and a drain pipe 3. The inlet 2 is located at the bottom of the pump body 1, and the drain pipe 3 is located near the lower end of the right side of the pump body 1. The drain pipe 3 has a concave structure, and a branch pipe 31 is installed at the center of the right side of the drain pipe 3. An outer sleeve 32 is located at the top of the pump body 1 and is fitted onto the outside of the pump body 1. The length of the outer sleeve 32 is three-quarters of the length of the pump body 1, and the inner diameter of the outer sleeve 32 is larger than the diameter of the pump body 1. The middle section of the inner wall of the outer sleeve 32... Several sets of toothed blocks 33 are arranged in a circle. A cooling mechanism 4 is provided between the inner wall of the upper end of the outer sleeve 32 and the top of the pump body 1. The cooling mechanism 4 includes a water inlet component 5 and a water distribution component 6. When the pump body 1 is started, water inside the shallow area is drawn into the pump body 1 through the water inlet 2 and then transmitted through the drain pipe 3. Part of the water is discharged to the outside through the branch pipe 31, while the other part of the water source passes through the water inlet component 5. The water source is filtered by the water inlet component 5, and then the filtered natural water source is sprayed onto the surface of the pump body 1 for physical cooling.

[0037] The water inlet assembly 5 includes a water purification cylinder 50, the cylinder of which is composed of an upper top cylinder 501 and a lower top cylinder 502, which are rotatably connected. The upper end of the drain pipe 3 extends into the upper top cylinder 501 near the right side. A circular hollow turntable 51 is provided near the center inside the upper top cylinder 501. A rotating rod is fixedly connected between the center of the front end of the hollow turntable 51 and the inner wall of the front end of the upper top cylinder 501. A rotating rod 52 extends to the front end of the upper cylinder 501 and is fixedly connected to a motor 53. A transmission wheel 54 is provided on the outside of the rotating rod 52 near the end of the hollow turntable 51. The lower half of the left side and the upper half of the right side of the hollow turntable 51 are both open. A material distribution plate 55 is rotatably connected inside the hollow turntable 51. The material distribution plate 55 is hollow and its diameter is the same as the inner diameter of the hollow turntable 51. When the water inlet assembly 5 is running, the water source is transported to the inside of the distribution plate 55 through the drain pipe 3 and the upper opening of the hollow turntable 51. After being filtered by the mesh of the distribution plate 55, the impurities in the water source are filtered at the upper notch of the upper opening of the hollow turntable 51. The water source falls through the hollow hole and is discharged through the lower left opening of the distribution plate 55 and falls into the lower top cylinder 502. Finally, it is discharged outward through the drain pipe 2 512. The motor 53 is started at the same time, which drives the rotating rod 52, the transmission wheel 54 and the hollow turntable 51 to rotate. As the hollow turntable 51 rotates downward, it is convenient to scrape the impurity particles that remain at the upper opening and let them fall down to the surface of the guide mesh plate 57. Then, it slides down the inclined surface of the plate to the inside of the collection frame 56, thereby realizing the separation of water and impurities. This reduces the situation where the particulate matter device pump 1 is damaged when the external water source cools down or the pump 1 stops operating due to particulate matter jamming.

[0038] A material collection frame 56 is provided on the right side of the upper cylinder 501 near the lower end, and a frame opening is provided on the left side of the material collection frame 56. A guide mesh plate 57 is hinged inside the frame opening. The guide mesh plate 57 is inclined with the left side higher than the right side, and two-thirds of its left side plate extends into the upper cylinder 501 and is located at the lower right side of the hollow turntable 51. As the hollow turntable 51 rotates downward, it facilitates the scraping of impurity particles that remain at the upper opening and their falling downward onto the surface of the guide mesh plate 57. Then, the inclined surface of the plate slides down into the material collection frame 56, thereby achieving the separation of water and impurities. This reduces the possibility of damage to the particulate matter device pump 1 caused by external water cooling or the pump 1 stopping due to particulate matter jamming. A blade-shaped abutment 58 is provided on the lower left side of the guide mesh plate 57, and the blade-shaped abutment 58 is internally connected to... There is a rotating rod 59, the rear end of which is rotatably connected to the inner wall of the rear end of the upper top cylinder 501, and a transmission wheel 510 is fixedly installed at its front end. The transmission wheel 510 and the transmission wheel 54 are connected by a belt 511. The guide screen 57 can also filter the splashed water source and the water source mixed with impurities. At the same time, the belt 511 drives the two sets of transmission wheels 510 to rotate, forcing the rotating rod 59 and the rotating rod 514 to rotate. When the rotating rod 59 rotates, it can drive the leaf-shaped abutment 58 to rotate and intermittently press the left end of the guide screen 57 into a raised shape. This can not only accelerate the discharge rate of impurity particles on the surface of the guide screen 57, but also reduce the situation of impurity particles getting stuck on the surface of the guide screen 57 by the collision between the guide screen 57 and the leaf-shaped abutment 58, thus improving the screening efficiency.

[0039] Example 2:

[0040] like Figure 4 and Figure 5As shown, drain pipes 512 are fixedly installed at equal intervals on the outer surface of the lower top cylinder 502. The drain pipes 512 are L-shaped and extend to the lower end of the lower top cylinder 502. Several sets of toothed grooves 513 are evenly arranged on the inner wall of the lower top cylinder 502 near the upper opening. A rotating rod 514 is rotatably connected to the center of the inner wall at the front end of the lower top cylinder 502 near the upper end. The rod of the rotating rod 514 extends to the center of the lower top cylinder 502 and is fixedly connected to a redirecting gear 515. A transmission wheel 510 is fixedly installed at the middle end of the rotating rod 514. Both sets of transmission wheels 510 are connected to the transmission wheel 54 via belts 511. A rotating shaft 516 is rotatably connected to the center of the lower top cylinder 502. Furthermore, several sets of blades 517 are fixedly installed at equal intervals on the outside of the rotating shaft 516. A gear disk 518 is fixedly installed at the top of the rotating shaft 516. The gear disk 518 is connected to the reversing gear 515. A gear disk 519 is engaged at the right side of the gear disk 518 at the opening of the lower top cylinder 502. The other end of the gear disk 519 is engaged with the tooth groove 513. When the rotating rod 514 rotates, the reversing gear 515 engages with the gear disk 518, thereby driving the rotating shaft 516 and the blades 517 to rotate. The engagement of the gear disk 518 and the gear disk 519 can drive the lower top cylinder 502 to rotate in the opposite direction, which is opposite to the rotation direction of the blades 517 and the upper top cylinder 501, thereby accelerating the discharge rate of water in the lower top cylinder 502.

[0041] Example 3:

[0042] In conventional devices, water is typically sprayed from the top of the pump body 1, impacting the top surface of the pump body 1 and causing the water to splash in all directions. This not only makes it difficult to cool down parts other than the top of the pump body 1, creating a heat dissipation dead zone, but also causes energy consumption due to continuous inefficient water spraying, reducing the cooling efficiency of the pump body 1. By setting up the water distribution component 6, uniform water spraying can be achieved.

[0043] like Figure 5 - Figure 9As shown, the water distribution component 6 includes a pentagonal frame 61, which is fitted onto the outside of the pump body 1. A circular groove 62 is provided at the apex of each pentagonal frame 61, and a fan-shaped clamping frame 63 is provided at the lower end of each set of circular grooves 62 at the bottom of the pentagonal frame 61. A disc 64 is rotatably connected inside the clamping frame 63. A bearing 65 is fixedly installed at the center of the bottom of the disc 64, and the lower end of the bearing 65 passes through the clamping frame 63 and is fixedly connected to a geared disc 36. The geared disc 36 meshes with a toothed block 33. A water collection groove is provided inside the disc 64. 67. The bottom opening of the second drain pipe 512 passes through the circular groove 62 and is rotatably connected to the top of the disc 64. The water collection tank 67 is connected to the second drain pipe 512. The radius of the disc 64 is smaller than the radius of the clamping frame 63. An arc-shaped abutment 68 is hinged to the side of the disc 64 near the inside of the clamping frame 63. A push plug 69 is hinged to the inner ring surface of the other end of the arc-shaped abutment 68. The push plug 69 passes through the inside of the water collection tank 67. A nozzle 610 is provided inside the water collection tank 67 at the opposite end of the push plug 69. The nozzle 610 is close to the outer surface of the pump body 1.

[0044] Filtered water is distributed through multiple sets of drain pipes 512 to the water collection tank 67 of the disc 64, and then sprayed onto the outer surface of the pump body 1 through nozzles 610, achieving multi-directional water spraying and cooling of the pump body 1 surface. The lower top cylinder 502 drives the water distribution assembly 6 to rotate through the drain pipes 512, thereby utilizing the multiple sets of nozzles 610 rotating around the pump body 1 to achieve uniform water spraying onto the pump body 1, thus improving the cooling effect. Furthermore, when the pentagonal frame 61 rotates, the geared disc 66 meshes with the gear block 33, forcing the bearing 65 and the disc 64 to engage. 4. Rotating inside the clamping frame 63, when the arc-shaped abutment 68 rotates to the inside of the clamping frame 63, the arc-shaped abutment 68 presses against the inner wall of the clamping frame 63, forcing the push plug 69 to press against the inside of the water collection tank 67, thereby realizing the spray nozzle 610 spraying water onto the surface of the pump body 1 for cooling. When the arc-shaped abutment 68 rotates to the outside of the clamping frame 63, under the action of the hinge force, the arc-shaped abutment 68 resets and pulls out the push plug 69. At this time, the spray nozzle 610 stops spraying outward, realizing intermittent water spraying, so as to reduce the energy consumption caused by continuous water spraying.

[0045] This invention also discloses a method for using an overheat protection device for a water pump, specifically including the following steps:

[0046] Step 1: Start the pump body 1. The water inside the shallow area is drawn into the pump body 1 through the inlet 2 and then transmitted through the drain pipe 3. Part of the water is discharged to the outside through the branch pipe 31, while the other part of the water source passes through the water inlet component 5. The water source is filtered by the water inlet component 5, and then the filtered natural water source is sprayed onto the surface of the pump body 1 for physical cooling.

[0047] Step 2: When the water inlet assembly 5 is running, the water source is transported to the inside of the distribution plate 55 through the drain pipe 3 and the upper opening of the hollow turntable 51. After being filtered by the mesh of the distribution plate 55, the impurities in the water source are filtered at the upper notch of the upper opening of the hollow turntable 51. The water source falls through the hollow hole and is discharged through the lower left opening of the distribution plate 55 and falls into the lower top cylinder 502. Finally, it is discharged outward through the drain pipe 2 512. Simultaneously, the motor 53 is started, which drives the rotating rod 52, the transmission wheel 54 and the hollow turntable 51 to rotate. As the hollow turntable 51 rotates downward, it is convenient to scrape the impurity particles that remain at the upper opening and let them fall down to the surface of the guide mesh plate 57. Then, it slides down the inclined surface of the plate to the inside of the collection frame 56, thereby achieving the separation of water and impurities. This reduces the situation where the particulate matter device pump body 1 is damaged when the external water source is cooled or the pump body 1 stops operating due to particulate matter jamming.

[0048] Furthermore, the guide screen 57 can also filter splashed water and water mixed with impurities. At the same time, the belt 511 drives the two sets of transmission wheels 510 to rotate, forcing the rotating rods 59 and 514 to rotate. When the rotating rod 59 rotates, it can drive the leaf-shaped abutment 58 to rotate and intermittently press against the left end of the guide screen 57, causing it to tilt upwards. This not only accelerates the discharge rate of impurity particles on the surface of the guide screen 57, but also reduces the situation of impurity particles getting stuck on the surface of the guide screen 57 by the collision between the guide screen 57 and the leaf-shaped abutment 58, thus improving the screening efficiency.

[0049] Step 3: When the rotating rod 3 514 rotates, the reversing gear 515 meshes with the gear disk 1 518, thereby driving the rotating shaft 516 and the blade 517 to rotate. The gear disk 1 518 meshes with the gear disk 2 519, which can drive the lower top cylinder 502 to rotate in the opposite direction, and opposite to the rotation direction of the blade 517 and the upper top cylinder 501, thereby accelerating the discharge rate of water in the lower top cylinder 502.

[0050] Step 4: The filtered water is distributed through multiple sets of drain pipes 512 to the water collection tank 67 of the disc 64, and then sprayed onto the outer surface of the pump body 1 through the nozzles 610. The lower top cylinder 502 drives the water distribution assembly 6 to rotate through the drain pipes 512. This utilizes the multiple sets of nozzles 610 rotating around the pump body 1 to achieve uniform water spraying onto the pump body 1, thereby improving the cooling effect. Furthermore, when the pentagonal frame 61 rotates, the geared disc 66 meshes with the gear block 33, forcing the bearing 65 and the disc 64 to engage within the clamping frame 63. When the arc-shaped abutment 68 rotates to the inside of the clamping frame 63, it presses against the inner wall of the clamping frame 63, forcing the push plug 69 to press against the inside of the water collection tank 67, thereby enabling the nozzle 610 to spray water onto the surface of the pump body 1 for cooling. When the arc-shaped abutment 68 rotates to the outside of the clamping frame 63, under the action of the hinge force, the arc-shaped abutment 68 resets and pulls the push plug 69 outward. At this time, the nozzle 610 stops spraying outward, realizing intermittent water spraying to reduce energy consumption caused by continuous water spraying.

4. The overheat protection device for a water pump according to claim 1, characterized in that, The specific usage method of this overheat protection device includes the following steps: Step 1: Start the pump body (1), and draw water from the shallow area into the pump body (1) through the inlet (2). Then, it is transmitted through the drain pipe (3). Part of the water is discharged to the outside through the branch pipe (31), while the other part of the water source passes through the water inlet assembly (5). The water source is filtered by the water inlet assembly (5), and the filtered natural water source is sprayed onto the surface of the pump body for physical cooling. Step 2: When the water inlet assembly (5) is running, the water source is transported to the inside of the distribution plate (55) through the drain pipe 1 (3) and the upper opening of the hollow turntable (51). After being filtered by the mesh of the distribution plate (55), the impurities in the water source are filtered at the upper notch of the upper opening of the hollow turntable (51), while the water source falls through the hollow hole and is discharged through the opening at the lower left end of the distribution plate (55) and falls into the lower top cylinder (502), and then is discharged outward through the drain pipe 2 (512). The motor is started simultaneously. 53), its drive rod (52), transmission wheel (54) and hollow turntable (51) rotate. As the hollow turntable (51) rotates downward, it is convenient to scrape the impurity particles that remain at the upper opening and drop them downward to the surface of the guide mesh plate (57). Then, the inclined surface of the plate slides down to the inside of the collection frame (56), thereby achieving the separation of water and impurities, reducing the damage to the particulate matter device pump body (1) caused by external water cooling or the pump body 1 stopping due to particulate matter jamming. Furthermore, the guide screen (57) can also filter the splashed water source and the water source mixed with impurities. At the same time, the belt (511) drives the two sets of transmission wheels (510) to rotate, forcing the rotating rod (59) and the rotating rod (514) to rotate. When the rotating rod (59) rotates, it can drive the leaf-shaped abutment (58) to rotate and intermittently press the left end of the guide screen (57) to lift up. This can not only accelerate the discharge rate of impurity particles on the surface of the guide screen (57), but also reduce the situation of impurity particles getting stuck on the surface of the guide screen (57) by the collision between the guide screen (57) and the leaf-shaped abutment (58), thus improving the screening efficiency. Step 3: When the rotating rod 3 (514) rotates, the reversing gear (515) meshes with the gear disk 1 (518), thereby driving the rotating shaft (516) and the blade (517) to rotate. The gear disk 1 (518) meshes with the gear disk 2 (519), thereby driving the lower top cylinder (502) to rotate in the opposite direction, and opposite to the rotation direction of the blade (517) and the upper top cylinder (501), thereby accelerating the discharge rate of water in the lower top cylinder (502). Step 4: The filtered water is distributed to the water collection tank (67) of the disc (64) through multiple sets of drain pipes 2 (512), and then sprayed onto the outer surface of the pump body (1) through the nozzles (610). The lower top cylinder (502) drives the water distribution component (6) to rotate through the drain pipes 2 (512). In this way, the multiple sets of nozzles (610) rotate around the pump body (1) to achieve uniform spraying of water to the pump body (1) and improve the cooling effect. When the pentagonal frame bar (61) rotates, the toothed disc 3 (66) meshes with the toothed block (33), forcing the bearing (65) and the disc (64) to be clamped in the frame. (63) Internal rotation: When the arc-shaped abutment (68) rotates to the inside of the clamping frame (63), the arc-shaped abutment (68) presses against the inner wall of the clamping frame (63), forcing the push plug (69) to press against the inside of the water collection tank (67), thereby realizing the nozzle (610) spraying water to the surface of the pump body (1) for cooling. When the arc-shaped abutment (68) rotates to the outside of the clamping frame (63), under the action of the hinge force, the arc-shaped abutment (68) resets and pulls out the push plug (69). At this time, the nozzle (610) stops spraying outward, realizing intermittent water spraying, so as to reduce the energy consumption caused by continuous water spraying.
