DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the present invention belongs. "Including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0029] In view of the problems existing in the prior art, an embodiment of the present invention provides a water pump with an anti-clogging function, such as Figure 1 and Figure 3As shown, the water pump with anti-clogging function includes a water pump body 1, which is arranged in a supporting box 2, and a water inlet pipe 3 connected to the water inlet of the water pump body 1, and the water inlet pipe 3 is used for liquid to enter the water pump body 1. In the prior art, impurities also enter the water pump body 1 through the water inlet pipe 3, resulting in the accumulation of impurities in the water pump body 1, thereby causing the water pump body 1 to be blocked. In the embodiment, a filter screen 4 is arranged on the water inlet pipe 3, and the setting of the filter screen 4 can block impurities on the right side of the filter screen 4 to prevent impurities from entering the water pump body 1; as well as a first anti-clogging mechanism 5 and a second anti-clogging mechanism 6. It is worth noting that the first anti-clogging mechanism 5 and the second anti-clogging mechanism 6 are separately or combined with the filter screen. The cooperation of the net 4 can realize the seat function of efficiently preventing blockage. Specifically, the first anti-blockage mechanism 5 and the second anti-blockage mechanism 6 are respectively arranged on both sides of the filter net 4, wherein the first anti-blockage mechanism 5 shakes out the blockage in the mesh of the filter net 4 by vibration to achieve unblocking, and the second anti-blockage mechanism 6 cleans the sediment deposited on the surface of the filter net 4 to achieve unblocking. Therefore, in one example, the first anti-blockage mechanism 5 and the filter net 4 are used to prevent the blockage of the water pump body 1, in another example, the second anti-blockage mechanism 6 and the filter net 4 are used to prevent the blockage of the water pump body 1, and in the third example, the first anti-blockage mechanism 5 and the second anti-blockage mechanism 6 work together with the filter net 4 to prevent the blockage of the water pump body 1.

[0030] In one embodiment, Figure 2 As shown, the first anti-blocking mechanism 5 includes a vibration ball 51 that contacts the side wall of the filter screen 4 (which can be understood as the left side wall), and the end of the vibration ball 51 away from the filter screen 4 (which can be understood as the left end) is fixedly connected to a vibration spring 52, and the free end of the vibration spring 52 is fixedly connected to a fixing rod 53, and the free end of the fixing rod 53 (which can be understood as the left end) is fixedly connected to a sealing plug 54. It is worth noting that the right end of the sealing plug 54 is set to a round head structure, so that the opposite direction can be avoided. The left-moving liquid causes obstruction; the sealing plug 54 is plugged in the bell tube 56, and the sealing plug 54 blocks the bell tube 56; the bell tube 56 is fixedly arranged on the inner wall of the water inlet pipe 3, and the combined structure of the sealing plug 54 and the bell tube 56 is used to divide the inner cavity of the water inlet pipe 3 into two non-connected cavities; the bell tube 56 is a trumpet-shaped structure, and the opening size of the end of the bell tube 56 away from the filter screen 4 (which can be understood as the left end) is smaller than the opening size of the end close to the filter screen 4 (which can be understood as the right end).

[0031] In one embodiment, Figure 2As shown, the first anti-blocking mechanism 5 also includes a support plate 55, which is fixedly connected to the sealing plug 54, and the support plate 55 and the trumpet tube 56 are arranged to abut against each other at one end thereof, and a first guide support assembly 57 having one end fixedly connected to the side wall of the support plate 55 and the other end fixedly connected to the outer wall of the trumpet tube 56. The first guide support assembly 57 includes a first guide support rod 571, a first guide support tube 572 and a first guide support spring 573. The first guide support rod 571 is movably inserted in the first guide support tube 572, and the first guide support spring 573 is wound around the outside of the first guide support rod 571, and one end of the first guide support spring 573 is fixedly connected to the side wall of the first guide support rod 571, and the other end of the first guide support spring 573 is fixedly connected to the outer wall of the first guide support tube 572.

[0032] In this embodiment, after the liquid passes through the filter screen 4, impurities are filtered and deposited on the right side of the filter screen 4; after the liquid passes through the filter screen 4, when the sealing plug 54 is located in the bell tube 56, the liquid is blocked on the right side of the bell tube 56. As the liquid is continuously injected into the right side of the bell tube 56, the hydraulic pressure on the right side of the bell tube 56 becomes larger and larger, and together with the suction force of the water pump body 1, a force is exerted on the sealing plug 54. When the combined force of the suction force and the hydraulic pressure (the direction of the force is to the left) is greater than the pulling force of the first guide support assembly 57 on the support plate 55 to the right, the support plate 55 will pull the sealing plug 54 to move to the left relative to the bell tube 56. When the sealing plug 54 is detached, the support plate 55 will pull the sealing plug 54 to move to the left relative to the bell tube 56. When leaving the bell tube 56, the liquid will be input into the water pump body 1 from the left end opening of the bell tube 56. As the liquid flows out, the leftward force exerted on the supporting plate 55 and the sealing plug 54 decreases. At this time, under the pulling of the first guide support assembly 57, the supporting plate 55 and the sealing plug 54 move quickly to the right to carry out the next cycle. When the sealing plug 54 moves to the right, it will hit the filter screen 4 with the vibration ball 51 through the fixing rod 53 and the vibration spring 52. The collision will cause the filter screen 4 to produce mechanical vibration, thereby shaking out the impurities in the mesh of the filter screen 4, thereby maintaining the excellent filtering performance of the filter screen 4 and preventing blockage.

[0033] In one embodiment, Figure 3 and Figure 4As shown, the second anti-clogging mechanism 6 includes a driving assembly, which is used to drive the push plate assembly 66 to move up and down. During the downward movement of the push plate assembly 66, impurities deposited on the right surface of the filter screen 4 can be removed; the driving assembly is arranged on the outer wall of the water inlet pipe 3, and the driving end of the driving assembly is fixedly connected to a connecting rod 64, and the free end of the connecting rod 64 is fixedly connected to a first push-pull rod 65, the first push-pull rod 65 is vertically arranged, and the lower end of the first push-pull rod 65 is connected to a push plate assembly 66, the push plate assembly 66 is movably arranged in a movable hole 67, and the movable hole 67 is opened on the top plate of the water inlet pipe 3, and the push plate assembly 66 is slidably connected to the filter screen 4 and the movable hole 67 The left end of the push plate assembly 66 is slidably connected to the filter screen 4, which can more effectively clean up the impurities deposited on the filter screen 4; the push plate assembly 66 includes a U-shaped section, and a trumpet-shaped pipe section connected to the lower end of the U-shaped section, and the cleaned impurities are deposited at the U-shaped section, and the trumpet-shaped pipe section is used to gather the impurities removed from the filter screen 4 to the bottom of the push plate assembly 66, so that all the impurities will be collected in the U-shaped section during the downward movement of the push plate assembly 66; a plurality of drainage holes 68 are provided on the U-shaped section; the drainage holes 68 are provided to drain the liquid in the push plate assembly 66 when the push plate assembly 66 moves downward, so as to prevent the impurities from moving out of the push plate assembly 66 due to the disturbance of the liquid.

[0034] In the process of preventing blocking by the second anti-blocking mechanism 6 alone and in cooperation with the filter screen 4, the downward movement of the push plate assembly 66 is driven by the power system. In one embodiment, Figure 3 As shown, the driving assembly includes a driving cylinder 61, and the driving cylinder 61 is fixedly arranged on the outer top wall of the fixed cylinder 62, and the fixed cylinder 62 is fixedly arranged on the outer side wall of the water inlet pipe 3. The driving upper end of the driving cylinder 61 is connected with a cylinder arm 63, and the upper end of the cylinder arm 63 is fixedly connected to the connecting rod 64, wherein the first push-pull rod 65 is movably inserted into the top plate of the fixed cylinder 62, and the fixed cylinder 62 cover is arranged outside the filter screen 4 and the movable hole 67.

[0035] In this embodiment, the driving cylinder 61 is set to control the up and down movement of the push plate assembly 66 through the power system. Specifically, when the driving cylinder 61 is started, the operation of the driving cylinder 61 will drive the cylinder arm 63 to move up and down. The up and down movement of the cylinder arm 63 will carry the push plate assembly 66 upward or downward through the connecting rod 64 and the first push-pull rod 65. During the downward movement, the push plate assembly 66 scrapes off the sediment deposited on the right surface of the filter screen 4.

[0036] In the process of preventing blocking by the first anti-blocking mechanism 5 and the second anti-blocking mechanism 6 in cooperation with the filter screen 4, in order to reduce production costs and improve the high efficiency performance of the equipment, in one embodiment, as Figure 5 As shown, the driving assembly is a linkage mechanism 7, and the linkage mechanism 7 is used for the linkage of the first anti-blocking mechanism 5 and the second anti-blocking mechanism 6, so that the unblocking process of the first anti-blocking mechanism 5 and the second anti-blocking mechanism 6 can be realized without adding a power source, wherein the power source of the second anti-blocking mechanism 6 is provided by the leftward liquid pressure and the suction force of the water pump body 1, and the reset pulling force of the first guide support assembly 57, and the power source of the first anti-blocking mechanism 5 is generated by the linkage of the movement process of the second anti-blocking mechanism 6. The linkage mechanism 7 includes an elastic rod 71 with one end fixedly connected to the side wall of the sealing plug 54 and the other end hinged to the front end edge of the driving gear 72. The elastic rod 71 is movably inserted into the top plate of the water inlet pipe 3. The driving gear 72 is fixedly sleeved outside the rotating rod 73, and the rotating rod 73 is rotatably set on the support seat 74. The support seat 74 is fixedly set on the outer side wall of the water inlet pipe 3. The driving gear 72 is meshed with a spur rack 75, and the spur rack 75 is fixedly set on the side wall of the first push-pull rod 65.

[0037] The linkage mechanism 7 in this embodiment is used for the linkage of the first anti-blocking mechanism 5 and the second anti-blocking mechanism 6. Specifically, when the sealing plug 54 moves to the left, the elastic rod 71 will pull the driving gear 72 to rotate clockwise. The rotation of the driving gear 72 will move the push plate assembly 66 downward through the spur rack 75 and the first push-pull rod 65 to scrape off the sediment deposited on the right surface of the filter screen 4. When the sealing plug 54 is pulled to the right by the first guide support assembly 57 to make a reset movement, the elastic rod 71 will push the driving gear 72 to rotate counterclockwise. The rotation of the driving gear 72 will move the push plate assembly 66 upward through the spur rack 75 and the first push-pull rod 65 to prepare for the next scraping process. Since the movement of the sealing plug 54 is carried out in a left-right cycle, the anti-blocking process of the first anti-blocking mechanism 5 and the second anti-blocking mechanism 6 will continue as long as the water pump body 1 is working, which can achieve a high-efficiency unblocking effect.

[0038] In order to prevent the debris scraped off by the push plate assembly 66 from being re-suspended in the liquid, in one embodiment, as shown in FIG. Figure 6 and Figure 7As shown, the water pump with anti-clogging function also includes a collecting mechanism 8, which is used to collect impurities scraped by the push plate assembly 66; the collecting mechanism 8 includes a collecting hole 81 opened on the bottom plate of the water inlet pipe 3, and the collecting hole 81 and the vibration ball 51 are respectively arranged on both sides of the filter screen 4 (it can be understood that the collecting hole 81 is arranged on the right side of the filter screen 4, and the vibration ball 51 is arranged on the left side of the filter screen 4), and a side wall of the collecting hole 81 and a side surface of the filter screen 4 are arranged on the same vertical line (it can be understood that the vertical right side wall of the filter screen 4 and the vertical left side wall of the collecting hole 81 are arranged on the same vertical line), so that the scraped impurities can all enter the collection box 82; the push plate assembly 66 can be slidably arranged in the collecting hole 81, so that there is no gap between the lower end of the trumpet-shaped pipe section of the push plate assembly 66 and the collecting hole 81, and the liquid will not flow downward from the two. On the one hand, it can play a sealing role, and on the other hand, it can press the impurities in the U-shaped section downward through the downward water pressure; the collecting mechanism 8 also includes a collecting box 82 arranged directly below the collecting hole 81, and the inner cavity of the collecting box 82 is interconnected with the hole cavity of the collecting hole 81. The collecting box 82 is fixedly arranged on the lower end surface of the water inlet pipe 3. The setting of the collecting box 82 is used to collect scraped impurities. Specifically, after the push plate assembly 66 enters the collecting hole 81, the impurities are downwardly moved into the collecting box 82 along with the liquid in the push plate assembly 66. Due to the presence of the drainage hole 68, after the push plate assembly 66 enters the collecting hole 81, the liquid will provide pressure downward through the drainage hole 68 or the liquid will directly flow downward from the drainage hole 68, thereby flushing the impurities adhered to the U-shaped section into the collecting box 82. It is worth noting that the hole of the drainage hole 68 is very small, so the water discharged through the drainage hole 68 is almost negligible.

[0039] In order to prevent the liquid from flowing out of the collecting hole 81 when the push plate assembly 66 is not moving downward, in one embodiment, Figure 8 and Fig. 9As shown, the water pump with anti-clogging function also includes a leak-proof mechanism 9 for sealing the collecting hole 81, and the leak-proof mechanism 9 includes a sealing plate 91, and the sealing plate 91 is movably arranged in a first sealing groove 92, and the first sealing groove 92 is opened on the water inlet pipe 3, and the water inlet pipe 3 is also provided with a second sealing groove 94 which is interconnected with the first sealing groove 92, and a second push-pull rod 95 is movably arranged in the second sealing groove 94, one end of the second push-pull rod 95 is arranged to be in contact with the pushing plate assembly 66, and the other end of the second push-pull rod 95 is hinged on the upper end surface of the sealing plate 91, and a third sealing groove 96 is opened on the side wall of the collecting hole 81, and the third sealing groove 96 and the sealing plate 91 are matched with each other, and the sealing plate 91 and the third sealing groove 96 are respectively arranged on the opposite sides of the collecting hole 81.

[0040] The anti-leakage mechanism 9 in this embodiment can be used to block the collecting hole 81 to prevent liquid from flowing out of the collecting hole 81 when the push plate assembly 66 does not move downward. At the same time, the anti-leakage mechanism 9 has a reasonable structural design. When the push plate assembly 66 moves downward into the collecting hole 81, the collecting hole 81 will be opened to allow the scraped impurities to enter the collecting box 82. Specifically, as the push plate assembly 66 moves downward and the lower end of the push plate assembly 66 has not entered the collecting hole 81, the leak prevention mechanism 9 seals the collecting hole 81. When the push plate assembly 66 enters the collecting hole 81, the push plate assembly 66 is responsible for sealing the collecting hole 81. As the push plate assembly 66 continues to move downward, it will resist the rightward movement of the second push-pull rod 95. The rightward movement of the second push-pull rod 95 will move with the sealing plate 91. As the sealing plate 91 continues to move, the left end of the sealing plate 91 will move outside the third sealing groove 96, thereby opening the collecting hole 81. At this time, the impurities in the push plate assembly 66 will enter the collecting box 82 through the collecting hole 81 and be collected.

[0041] In one embodiment, if Fig. 9 As shown, the leakage prevention mechanism 9 also includes a second guide support assembly 93, one end of which is fixedly connected to the side wall of the sealing plate 91, and the other end of which is fixedly connected to the side wall of the first sealing groove 92. The second guide support assembly 93 includes a second guide support rod 931, a second guide support cylinder 932 and a second guide support spring 933. The second guide support rod 931 is movably inserted in the second guide support cylinder 932, and the second guide support spring 933 is wound around the outside of the second guide support rod 931, and one end of the second guide support spring 933 is fixedly set on the side wall of the second guide support rod 931, and the other end of the second guide support spring 933 is fixedly connected to the outer side wall of the second guide support cylinder 932.

[0042] The setting of the second guide support assembly 93 in this embodiment can serve as a guide and support for the movement of the sealing plate 91, so that the sealing plate 91 can only move left and right in the horizontal direction. At the same time, when the second push-pull rod 95 loses the downward resistance force of the push plate assembly 66, it will provide a driving force to push the sealing plate 91 to make a reset movement to the left, so that the left end of the sealing plate 91 enters the third sealing groove 96 again, completing the re-sealing of the collecting hole 81.

[0043] When a large amount of impurities are collected in the push plate assembly 66, in order to prevent the impurities from falling out of the push plate assembly 66 and entering the collection box 82, in one embodiment, as shown in FIG. Fig.10 As shown, the push plate assembly 66 includes an outer push plate 661, and a push groove 662 opened on the inner side wall of the outer push plate 661, and the push groove 662 is opened on the U-shaped section; an inner push plate 663 is movably arranged in the push groove 662, and a push rod 664 is fixedly connected to the upper end surface of the inner push plate 663, and the push rod 664 is movably inserted into the outer push plate 661, and the upper end of the push rod 664 is fixedly connected to the lower end surface of the first push-pull rod 65, and a push spring 665 is wound around the push rod 664, one end of the push spring 665 is fixedly connected to the side wall of the push rod 664, and the other end of the push spring 665 is fixedly connected to the lower end surface of the first push-pull rod 65.

[0044] During operation, the sealing plate 91 will not completely enter the first sealing groove 92. In order to prevent impurities from being deposited on the first sealing groove 92, the left end of the first sealing groove 92 is set to an arc structure, but it is not only an arc structure. The setting of this structure will have a supporting and limiting effect on the downward moving push plate assembly 66. When the push plate assembly 66 hits the upper surface of the sealing plate 91, as the first push-pull rod 65 continues to move downward, the push rod 664 will carry the inner push plate 663 to move downward relative to the outer push plate 661. The occurrence of this movement can push the impurities in the push plate assembly 66 to the outside of the push plate assembly 66 through the inner push plate 663 and into the collection box 82.

[0045] Although the embodiments of the present invention are described in detail above, it is obvious to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations are within the scope and spirit of the present invention. Moreover, the present invention described herein may have other embodiments and may be implemented or realized in a variety of ways.
