Description

Technical Field

[0001] The present invention belongs to the technical field of water quality filtration of water intake machines, and specifically relates to a self-cleaning intelligent water intake machine. Background Art

[0002] In today's society, with the rapid development of technology, intelligent water intake machines, as a new type of water resource supply device, are gradually penetrating into our daily lives. For example, on the roadside of the city, when sanitation workers are cleaning the city roads and need to use liquid water, they can obtain liquid water through the intelligent water intake machines on the roadside of the city, which greatly facilitates the progress of urban cleaning work.

[0003] Currently, in order to save water resources, the water intake machines for sanitation workers usually pump the liquid water in the river into them to replace the supply of drinking water. The untreated liquid water in the river is completely suitable for road cleaning. However, during the specific use process, when the water pump pumps the liquid water in the river, it is easy to synchronously pump the sand grains in the river into the machine. Therefore, a filtering structure needs to be installed inside the water intake machine. And after using for a period of time, when the impurities filtered out by the filtering structure are too much, it is necessary to clean it to avoid affecting the subsequent water intake work. And most of the cleaning work is carried out manually, which is rather inconvenient.

[0021] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0022] As Figures 1 to 7 shown, a self-cleaning intelligent water dispenser according to an embodiment of the present invention includes a housing 1. A water pump 11 is fixedly connected to the side of the housing 1. The output end of the water pump 11 is connected and fixed to a water injection pipe 12. The water outlet end of the water injection pipe 12 is connected and fixed to a spray head 13 inserted into the housing 1. A water outlet switch 14 is connected and fixed to the side of the housing 1. A filter plate 2 is slidably connected inside the housing 1. A connecting member is fixedly connected to the top of the filter plate 2. The top of the connecting member is fixedly connected to a connecting frame 31. The end of the connecting frame 31 away from the connecting member penetrates to the outside of the housing 1. A hydraulic cylinder 3 is fixedly connected to the end of the connecting frame 31 located outside the housing 1. The hydraulic cylinder 3 is fixedly connected to the side of the housing 1, and the output end of the hydraulic cylinder 3 is fixedly connected to the end of the connecting frame 31; A plurality of first springs 21 are fixedly connected between the top of the filter plate 2 and the inner wall of the housing 1. A dredging frame 4 fixedly connected to the inner wall of the housing 1 is arranged below the filter plate 2. The dredging frame 4 includes a bracket fixedly connected to the inner wall of the housing 1 and further includes a plurality of ejector pins fixedly connected to the top of the bracket. The plurality of ejector pins are located directly below the filter holes on the filter plate 2. An air jet head 17 is inserted into the side of the housing 1 and above the hydraulic cylinder 3. An air charging pipe 16 is connected and fixed to the side of the air jet head 17. The end of the air charging pipe 16 away from the air jet head 17 is connected and fixed to an air charging pump 15. The air charging pump 15 is fixedly connected to the side of the housing 1. An outlet is provided at a position on the side of the housing 1 at the same height as the air jet head 17. The positions of the air jet head 17 and the outlet are symmetric about the center of the housing 1. A first magnet 22 is fixedly connected to the top of the filter plate 2. A support rod 51 fixed to the inner wall of the housing 1 is arranged below the dredging frame 4. A pressure sensor 5 is fixedly connected to the top of the support rod 51. A second magnet 52 having the same magnetism as the first magnet 22 is fixedly connected to the pressure-receiving end of the pressure sensor 5; When the current water intake machine is in use, the untreated liquid water in the river can fully be used for road cleaning. However, during the specific use process, when the water pump extracts the liquid water in the river, it is easy to synchronously draw in the sand grains in the river. Therefore, a filtering structure needs to be installed inside the water intake machine, and after using for a period of time, it needs to be cleaned, which is rather inconvenient. To solve the above problems, the embodiment of the present invention sets up multiple structures such as the dredging frame 4. The specific use process is as follows. When the water intake machine extracts the liquid water in the river, the water pump 11 draws the liquid water in the river into the through by an external pipeline, and then injects it into the spray head 13 through the water injection pipe 12, and then sprays it into the machine shell 1 through the spray head 13. The liquid water sprayed by the spray head 13 is dispersed through the filter plate 2, and the sand grains in the liquid water are filtered by the filter plate 2. It should be noted that a liquid level sensor (not shown in the accompanying drawings of the specification) is provided in the machine shell 1. When the liquid water in the machine shell 1 reaches a certain liquid level, the liquid level sensor controls the water pump 11 to stop extracting the liquid water. At this time, the liquid level of the liquid water in the machine shell 1 is below the dredging frame 4. After using for a period of time, when the filter plate 2 is blocked with a large amount of sand grains, as the spray head 13 sprays the liquid water downward, the content of the liquid water passing through per unit time decreases. Therefore, the downward impact force of the liquid water on the filter plate 2 increases, which causes the filter plate 2 to stretch the first spring 21 and move downward. When moving to the opening height of the side of the machine shell 1, the filter holes of the filter plate 2 are accurately inserted by the ejector pins in the dredging frame 4. Then, the ejector pins push out the sand grains blocked in the filter holes. At the same time, the filter plate 2 drives the first magnet 22 to move to a position where it repels the second magnet 52, that is, the second magnet 52 is subjected to the magnetic repulsion force, and then it exerts extrusion on the pressure receiving end of the pressure sensor 5. It should be noted that the liquid water passing through the filter plate 2 will also generate pressure on the top of the second magnet 52 due to the impact, but the generated pressure is small and will not affect the use of the pressure sensor 5. When the pressure receiving end of the pressure sensor 5 is extruded by the second magnet 52, the pressure sensor 5 sends a signal to the telescopic rod 72, and the telescopic rod 72 starts. The output end of the telescopic rod 72 drives the blocking plate 7 to move upward through the linkage frame 71 to open the opening. At the same time, the pressure sensor 5 sends a signal to the air pump 15, causing the air pump 15 to drive. Then, the air pump 15 injects air into the jet head 17 through the air injection pipe 16. Then, the jet head 17 sprays out an air flow. The air flow acts on the top of the filter plate 2, and the air flow is discharged through the opening. The sand grains on the top of the filter plate 2 are blown by the air flow and discharged through the opening. When the injection of the liquid water into the machine shell 1 ends, the filter plate 2 is no longer impacted. Under the action of the first spring 21, the filter plate 2 is driven to reset. The telescopic rod 72 drives the blocking plate 7 to reset through the linkage frame 71, and the air pump 15 is closed. The above process realizes the automatic cleaning of the filter plate 2, replacing the regular cleaning by the staff, which is convenient to use and reduces the labor consumption.

[0023] The input end of the air pump 15 is connected and fixedly connected with a water inlet pipe 18, and the bottom end of the water inlet pipe 18 passes through the interior of the casing 1; when the air pump 15 is working, the air pump 15 draws liquid water into the interior of the casing 1 through the water inlet pipe 18, and then injects it into the nozzle 17 through the air charging pipe 16. The nozzle 17 sprays the liquid water to the top of the filter plate 2, so that the sand particles on the top of the filter plate 2 are quickly driven by the liquid water and discharged through the opening. Compared with the movement of sand particles carried by air flow, the sand particles can be more effectively driven to move by liquid water, thereby improving the cleaning effect of the sand particles on the top of the filter plate 2.

[0024] like Figures 7 to 8 As shown, a receiving block 6 is fixedly connected to the bottom end of the dredging frame 4, and a rotating shaft 61 is rotatably connected to the bottom end of the receiving block 6. A plurality of water retaining inclined plates 62 are fixedly connected to the side of the rotating shaft 61 in an annular shape. A scraper 63 is fixedly connected to the bottom end of the rotating shaft 61, and the bottom end of the scraper 63 is in contact with the top end of the second magnetic block 52 without extrusion force. When liquid water is sprayed downward through the filter plate 2, the liquid water will act on the inclined surface of the water retaining inclined plate 62, so that the water retaining inclined plate 62 generates a torsional force. Under the action of the torsional force, the water retaining inclined plate 62 drives the rotating shaft 61 to rotate. The shaft 61 rotates, and the rotating shaft 61 drives the scraper 63 at the bottom to rotate, and the bottom end of the scraper 63 is in contact with the top of the second magnetic block 52 without extrusion force. Therefore, as the scraper 63 rotates, the scraper 63 will scrape off the dirt on the top of the second magnetic block 52 to prevent dirt from accumulating on the top of the second magnetic block 52 and hindering the magnetic force between the second magnetic block 52 and the first magnetic block 22. It should be pointed out that the bottom end of the first magnetic block 22 is inserted into the interior of the filter plate 2, so the surface of the bottom end of the first magnetic block 22 will not be attached to dirt.

[0025] An interception frame 41 is fixedly connected to the inner wall of the casing 1 at the middle height of the opening. The interception frame 41 is far away from the center of the filter plate 2. The connecting member includes a receiving frame 32. The top of the receiving frame 32 is fixedly connected to the top of the connecting frame 31. A pair of second springs are fixedly connected between the two ends of the receiving frame 32 and the filter plate 2. When the connecting member drives the filter plate 2 to move downward, one end of the filter plate 2 will be blocked by the interception frame 41. As the filter plate 2 moves further downward, the second spring at one end of the receiving frame 32 is compressed, and the second spring at the other end drives the filter plate 2 to move downward. At this time, the ejector pin of the dredging rack 4 has been inserted into the filter hole. As the filter plate 2 moves further downward, one end of the filter plate 2 is blocked, and the other end is tilted downward, and the end close to the opening is the tilted bottom end. Later, when the sand particles on the top of the filter plate 2 are driven by the jet head 17, the tilted filter plate 2 is conducive to the movement of the sand particles, making it easier for the sand particles to escape from the casing 1 from the opening. It should be pointed out that the bracket of the dredging rack 4 is made of elastic material and can be deformed with the ejector pin. In addition, the end of the filter plate 2 is arranged in an arc shape so that it will not be blocked when the filter plate 2 is tilted.

[0026] A plurality of elastic pieces 211 are fixedly connected to the inner wall of the casing 1 and above the filter plate 2. The end of the elastic piece 211 away from the inner wall of the casing 1 extends into the first spring 21. When the filter plate 2 moves downward, the first spring 21 is stretched, causing the strip metal of the first spring 21 to move downward, thereby squeezing the elastic piece 211. When the strip metal of the first spring 21 crosses the elastic piece 211, the elastic piece 211 vibrates. During vibration, it impacts the strip metal of the first spring 21, causing the first spring 21 to vibrate synchronously. The first spring 21 drives the filter plate 2 to vibrate synchronously, which is beneficial for the sand grains at the top end of the filter plate 2 to move away from the casing 1.

[0027] As Figures 9 to 14 shown, a plugging plate 7 is slidably connected to the side of the casing 1. Initially, the plugging plate 7 plugs the opening. A telescopic rod 72 is fixedly connected to the side of the casing 1 and above the plugging plate 7. A linkage frame 71 is fixedly connected between the output end of the telescopic rod 72 and the plugging plate 7. An intercepting frame 8 is fixedly connected to the side of the casing 1 and outside the plugging plate 7. A water receiving box 81 fixedly connected to the side of the casing 1 is arranged below the intercepting frame 8. A water receiving plate 82 is fixedly connected to the top end of the water receiving box 81. A water receiving groove 821 is opened at the top end of the water receiving plate 82. A water guide pipe 83 communicating with the water receiving groove 821 is arranged at the bottom end of the water receiving plate 82. The bottom end of the water guide pipe 83 is fixedly connected and communicated with a water storage tank 84. A recovery pipe 85 is fixedly connected and communicated between the water storage tank 84 and the input end of the water pump 11. When the liquid water is sprayed out by the jet head 17, the liquid water will carry the sand grains and be discharged through the opening, intercepted by the intercepting frame 8. Then the liquid water flows downward along the bottom end of the intercepting frame 8 and is received by the water receiving box 81. The sand grains inside the liquid water precipitate downward, and when the liquid water passes over the top end of the water receiving box 81, it flows into the water receiving groove 821 at the top end of the water receiving plate 82, and then flows downward through the water guide pipe 83 into the water storage tank 84. When the water pump 11 is started, the water pump 11 pumps the liquid water into the casing 1 through the recovery pipe 85, realizing the recovery of the discharged liquid water and preventing the liquid water from splashing onto the road and disturbing pedestrians.

[0028] A floating rod 841 is inserted into the top end of the water storage tank 84. A plugging block 842 is fixedly connected to the bottom end of the floating rod 841. Initially, the plugging block 842 plugs the pipe orifice where the recovery pipe 85 is inserted into the water storage tank 84. After the liquid water inside the water storage tank 84 is emptied, the floating rod 841 loses the buoyancy effect, and then the floating rod 841 will drive the plugging block 842 at the bottom end to move downward to plug the water inlet of the recovery pipe 85, preventing the water pump 11 from pumping in air through the recovery pipe 85, so that a large amount of air enters the casing 1, increasing the air pressure inside the casing 1 and hindering the injection of liquid water.

[0029] A discharge port 811 is provided at the bottom end of the water receiving box 81, a blocking piece 812 is provided at the bottom end of the discharge port 811, a support shaft 813 is fixedly connected to the side of the blocking piece 812, a fixing plate 814 is inserted into the side of the support shaft 813, the top of the fixing plate 814 is fixedly connected to the water receiving box 81, a third spring 815 is sleeved on the surface of the support shaft 813, one end of the third spring 815 is fixedly connected to the blocking piece 812, and the other end is fixedly connected to the fixing plate 814; The bottom end of the sealing piece 812 is provided with an elastic baffle 816, and the side of the elastic baffle 816 is provided with a receiving assembly fixedly connected to the bottom end of the water receiving box 81; when too much sand accumulates inside the water receiving box 81, the weight of the sand above the discharge port 811 is large, and the sand squeezes the sealing piece 812, so that the sealing piece 812 rotates based on the support shaft 813, and the end of the sealing piece 812 will gradually bend the elastic baffle 816, and finally pass over the elastic baffle 816 to open the discharge port 811, and the sand inside the water receiving box 81 will be discharged to the road surface through the discharge port 811, and finally be cleaned up by the sanitation workers when cleaning the road surface; further, the receiving assembly includes a receiving sleeve 817 fixed to the bottom end of the water receiving box 81, the elastic baffle 816 passes through the receiving sleeve 817, and the elastic baffle 8 16 An inclined surface is provided near the bottom end of the blocking piece 812, and a fourth spring 819 is fixedly connected to the end of the elastic baffle 816 away from the blocking piece 812, and a fixing frame 818 is fixedly connected between the end of the fourth spring 819 and the receiving sleeve 817; when the blocking piece 812 is not squeezed by sand particles, the blocking piece 812 will be reset and rotated through the third spring 815, and when the end is squeezed to the inclined surface at the bottom end of the elastic baffle 816, the elastic baffle 816 will be subjected to a lateral thrust, thereby causing the elastic baffle 816 to squeeze the fourth spring 819 to move laterally, and then the blocking piece 812 passes over the elastic baffle 816, and the elastic baffle 816 is reset and moved again. This process prevents the blocking piece 812 from being blocked by the elastic baffle 816 when it is reset and rotated, making it difficult to reset.

[0030] A pair of push plates 9 are slidably connected inside the water receiving box 81. A guide rod 91 is fixedly connected to the side of the push plate 9 away from the center of the water receiving box 81. The guide rod 91 penetrates to the outside of the water receiving box 81. A support frame 92 is sleeved on the end of the guide rod 91 located outside the water receiving box 81. A fifth spring 93 sleeved on the surface of the guide rod 91 is arranged between the support frame 92 and the water receiving box 81. A wind shield 94 is fixedly connected to the end of the guide rod 91 located outside the water receiving box 81. When the wind blows, the wind force will act on the surface of the large wind shield 94, causing the wind shield 94 to drive the push plate 9 at the end of the guide rod 91 to move inside the water receiving box 81. Cooperating with the fifth spring 93, the sand grains in the water receiving box 81 are pushed towards the discharge port 811, thereby facilitating the subsequent discharge of the sand grains from the discharge port 811. It should be noted that the magnitude of the wind force varies, so the cooperation with the fifth spring 93 enables the push plate 9 to reciprocate. Further, an elastic film (not shown in the accompanying drawings of the specification) is arranged between the tops of the pair of push plates 9. The elastic film can prevent sand grains from entering between the pair of push plates 9, resulting in difficulty for the sand grains to fall into the discharge port 811 for cleaning.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention.
