[0002] Water conservancy projects usually need to use water pipes when transporting water. In order to reduce the probability of debris entering the water pipes and blocking the water pipes, filters are usually installed in the water pipes to filter out the debris entering the water pipes.

DETAILED DESCRIPTION

[0033] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0034] like Figures 1 to 12 As shown, the water source filtering and algae removal device 100 of the embodiment of the present invention comprises a main pipeline 1, a filter plate 2, a mounting frame 3 and a reset spring 5. The main pipeline 1 has a water inlet 101 and a water outlet 102, the water inlet 101 is used to communicate with the water source, and the water outlet 102 is used to communicate with the water pipeline. The inner wall of the main pipeline 1 is provided with a sliding groove 103 extending along the axial direction of the main pipeline 1.

[0035] The filter plate 2 and the mounting frame 3 are spaced apart in the axial direction of the main pipe 1 in the main pipe 1. The filter plate 2 is arranged adjacent to the water inlet 101 of the main pipe 1. The filter plate 2 includes a plate body 201 and a sliding portion 202. The plate body 201 has a plurality of spaced apart filter holes 2011. The sliding portion 202 can slidably cooperate with the sliding groove 103 along the axial direction of the main pipe 1.

[0036] A plurality of ejector pins 4 are provided on one side of the mounting frame 3 adjacent to the filter plate 2. The plurality of ejector pins 4 correspond to the plurality of filter holes 2011 one by one. The ejector pins 4 extend along the axial direction of the main pipe 1. The ejector pins 4 are used to pass through the filter holes 2011 to eject the algae derivatives blocking the filter holes 2011. A return spring 5 is provided in the main pipe 1. The return spring 5 is used to provide an elastic force to the filter plate 2 along the axial direction of the main pipe 1 away from the ejector pins 4.

[0037] When the water source filtering and algae removal device 100 of the embodiment of the present invention is used, the water inlet 101 of the main pipe 1 is connected to the water source, and the water outlet 102 of the main pipe 1 is connected to the water delivery pipe. When the algae derivatives in the water source block the filter hole 2011, causing the water flow to be unable to flow through the filter hole 2011 normally, a pressure difference will be generated upstream and downstream of the filter hole 2011. Under the force of the upstream water pressure, the filter plate 2 will slide along the axial direction of the main pipe 1 toward the direction close to the ejector pin 4, so that the ejector pin 4 can enter the filter hole 2011 and push away the algae derivatives blocked in the filter hole 2011 or attached to the surface of the filter plate 2, so as to keep the filter plate 2 unobstructed. When the filter plate 2 is unobstructed, the water pressure difference upstream and downstream of the filter hole 2011 is reduced, and the filter plate 2 is reset under the elastic force of the reset spring 5, and the ejector pin 4 is separated from the filter hole 2011, ensuring that the water flow can flow through the filter hole 2011 normally.

[0038] Therefore, the water source filtering and algae removal device 100 of the embodiment of the present invention can achieve effective filtration and algae removal of the water source, ensure the cleanliness and safety of the water quality, and prevent algae derivatives in the water source from reducing the water flow rate of the main pipeline 1 due to clogging the filter plate 2, thereby greatly improving the water delivery efficiency.

[0039] In some embodiments, the plate body 201 is provided with a first through hole (not shown in the figure) extending along the thickness direction thereof, and the mounting frame 3 is provided with a first push rod 6 extending along the axial direction of the main pipeline 1, one end of the first push rod 6 passes through the first through hole, and the outer peripheral surface of the first push rod 6 is provided with a first slide groove 601 arranged spirally around.

[0040] A first sleeve 7 is rotatably provided on one side of the plate body 201 away from the ejector pin 4. The first sleeve 7 is sleeved on the first push rod 6. A first slide bar 8 extending radially of the first sleeve 7 is provided on the inner wall of the first sleeve 7. At least a portion of the first slide bar 8 is placed in the first slide groove 601 and slidably cooperates with the first slide groove 601, so that when the first push rod 6 moves relative to the first sleeve 7 in the axial direction of the main pipeline 1, it can drive the first sleeve 7 to rotate. A scraper 9 extending radially of the first sleeve 7 is provided on the outer circumferential surface of the first sleeve 7. The scraper 9 is used to scrape off algae derivatives on the filter plate 2.

[0041] Specifically, if Figure 8 , Fig. 9 and Fig.11 As shown, when the filter plate 2 moves in the axial direction of the main pipeline 1 toward the direction close to the ejector pin 4, the first push rod 6 can move relative to the first sleeve 7, and under the action of the first slide groove 601 and the first slide rod 8, the first push rod 6 can drive the first sleeve 7 to rotate. The first sleeve 7 can drive the scraper 9 to rotate while rotating, and the rotation of the scraper 9 can not only scrape off the algae derivatives attached to the filter plate 2, but also push the ejector pin 4 out of the filter hole 2011 to scrape off the algae derivatives, thereby improving the removal efficiency of the water source filtering and algae removal device 100 of the embodiment of the present invention.

[0042] Optionally, the length of the ejector pin 4 is the same as the depth of the filter hole 2011. If the length of the ejector pin 4 is set too long, for example, the length of the ejector pin 4 is greater than the depth of the filter hole 2011, there is a risk of the ejector pin 4 passing through the filter hole 2011 and interfering with the scraper 9. If the length of the ejector pin 4 is set too short, for example, the length of the ejector pin 4 is less than the depth of the filter hole 2011, the algae derivatives inside the filter hole 2011 cannot be completely ejected, resulting in incomplete cleaning. Because, by setting the length of the ejector pin 4 to be the same as the depth of the filter hole 2011, while effectively ensuring the working safety of the ejector pin 4, its cleaning reliability can also be effectively guaranteed.

[0043] Optionally, the diameter of the ejector pin 4 is d, and the inner diameter of the filter hole 2011 is D, wherein 1 / 3D≤d≤2 / 3D. For example, the diameter of the ejector pin 4 is 1 / 3, 1 / 2 or 2 / 3 of the diameter of the filter hole 2011. By reasonably designing the diameter of the ejector pin 4, the ejector pin 4 has sufficient force when pushing the algae derivative, ensuring that the ejector pin 4 can effectively clean the algae derivative in the filter hole 2011, but is not too large to damage the filter hole 2011 or the filter plate 2, which helps to improve the cleaning effect and reduce damage to the filtering device.

[0044] In some embodiments, there are multiple scrapers 9 , which are spaced apart along the circumference of the first sleeve 7 , and the scraper 9 has a first blade 901 and a second blade 902 that are oppositely disposed along the width direction thereof.

[0045] For example, Figure 6 As shown, when the filter plate 2 moves toward the ejector pin 4 in the axial direction of the main pipe 1, the first push rod 6 will drive the first sleeve 7 to rotate forward, and the first sleeve 7 will drive the scraper 9 to rotate forward. When the filter plate 2 is reset under the action of the reset spring 5, that is, when the filter plate 2 moves away from the ejector pin 4 in the axial direction of the main pipe 1, the first push rod 6 will drive the first sleeve 7 to rotate reversely, and the first sleeve 7 will drive the scraper 9 to rotate reversely. Since the scraper 9 has a first blade 901 and a second blade 902 that are arranged opposite to each other along its width direction, when the scraper 9 is in the process of forward and reverse rotation, the algae derivatives on the filter plate 2 will be scraped off, further improving the cleaning effect of the water source filtering and algae cleaning device 100 of the embodiment of the present invention.

[0046] In some embodiments, a sewage outlet 107 is provided at the bottom of the main pipe 1, a sewage storage tank 10 connected to the sewage outlet 107 is provided on the main pipe 1, and an opening and closing cover 11 for blocking the sewage outlet 107 is provided on the side of the filter plate 2 adjacent to the ejector pin 4. When the filter plate 2 moves in the direction close to the ejector pin 4, the opening and closing cover 11 opens the sewage outlet 107, so that the scraper 9 scrapes the algae derivatives on the filter plate 2 into the sewage storage tank 10.

[0047] For example, Figure 2 , Figure 3 and Figure 8As shown, when the filter plate 2 moves in the direction close to the ejector pin 4 in the axial direction of the main pipe 1, the filter plate 2 will drive the opening and closing cover 11 to move in the direction close to the ejector pin 4, and the opening and closing cover 11 will open the sewage outlet 107. After the scraper 9 scrapes the algae derivatives on the filter plate 2, they will enter the sewage storage tank 10 through the sewage outlet 107 under the action of gravity for storage. When the filter plate 2 is reset in the direction away from the ejector pin 4 in the axial direction of the main pipe 1, the filter plate 2 will drive the opening and closing cover 11 to move in the direction away from the ejector pin 4, and the opening and closing cover 11 will close the sewage outlet 107 to prevent the algae derivatives stored in the sewage storage tank 10 from returning to the main pipe 1 again to block the filter plate 2. It should be noted that the algae derivatives in the sewage storage tank 10 can be cleaned regularly to ensure that there is enough storage space in the sewage storage tank 10 for storing the scraped algae derivatives.

[0048] In some embodiments, the main pipeline 1 is provided with a first water hole 104 and a second water hole 105 on the pipe wall on both sides of the filter plate 2, the first water hole 104 is arranged near the water inlet 101, and a branch pipeline 12 is arranged between the first water hole 104 and the second water hole 105. A sealing valve plate 13 is arranged on the second water hole 105, and the sealing valve plate 13 is rotatably connected to the main pipeline 1, and a control component is arranged between the filter plate 2 and the sealing valve plate 13.

[0049] When the filter plate 2 moves along the axial direction of the main pipeline 1 toward the ejector pin 4, the control component controls the sealing valve plate 13 to rotate to open the second water hole 105. When the filter plate 2 moves along the axial direction of the main pipeline 1 toward the ejector pin 4, the control component controls the sealing valve plate 13 to rotate to close the second water hole 105.

[0050] Specifically, if Figures 2 to 8 As shown, when the filter plate 2 moves in the axial direction of the main pipeline 1 toward the direction close to the ejector pin 4, it means that the filter plate 2 has been blocked by the algae derivatives, resulting in a pressure difference between the water pressures on the upstream and downstream sides of the filter plate 2. When the pressure difference is greater than the elastic force of the reset spring 5, the filter plate 2 will overcome the elastic force of the reset spring 5 and move toward the ejector pin 4. At the same time, the main pipeline 1 is blocked by the algae derivatives, and the water flow of the main pipeline 1 is reduced. In the process of the filter plate 2 moving in the axial direction of the main pipeline 1 toward the ejector pin 4, the control component will control the sealing valve plate 13 to rotate to open the second water hole 105, so that part of the water flow upstream of the filter plate 2 flows to the downstream of the filter plate 2 through the branch pipeline 12, so as to effectively ensure the water flow and water delivery efficiency of the main pipeline 1.

[0051] Of course, the opening angle of the sealing valve plate 13 can be adjusted according to the displacement of the filter plate 2, so that the reduced water flow in the main pipeline 1 can be compensated by the branch pipeline 12 to effectively ensure the water delivery efficiency of the main pipeline 1.

[0052] In some embodiments, the control assembly includes a rotating shaft 14 and a second sleeve 15. The extending direction of the rotating shaft 14 is parallel to the extending direction of the main pipeline 1 and is rotatably connected to the pipe wall of the main pipeline 1, one end of the rotating shaft 14 is connected to the sealing valve plate 13, and the outer circumference of the other end of the rotating shaft 14 is provided with a second sliding groove 1401 arranged in a spiral manner.

[0053] The second sleeve 15 is coaxially arranged with the rotating shaft 14, one end of the second sleeve 15 is connected with the filter plate 2, and the other end of the second sleeve 15 is sleeved on the rotating shaft 14. A second slide bar 16 extending along the radial direction of the second sleeve 15 is arranged on the inner wall of the second sleeve 15, and the second slide bar 16 is placed in the second slide groove 1401 and slidably cooperates with the second slide groove 1401, so that when the second sleeve 15 moves relative to the rotating shaft 14 in the axial direction of the main pipeline 1, it can drive the rotating shaft 14 to rotate.

[0054] For example, Figure 7 , Fig.10 and Fig.12 As shown, when the filter plate 2 moves in the axial direction of the main pipeline 1, it can drive the second sleeve 15 to move in the axial direction of the main pipeline 1. When the second sleeve 15 moves in the axial direction of the main pipeline 1 relative to the rotating shaft 14, it can drive the rotating shaft 14 to rotate, which can effectively control the rotation of the sealing valve plate 13 and realize the opening and closing of the second water hole 105. The combination of the rotating shaft 14 and the second sleeve 15 can realize the rotation control of the sealing valve plate 13 and ensure that the opening and closing process of the second water hole 105 is smooth and accurate.

[0055] The sliding fit between the second slide groove 1401 spirally arranged on the rotating shaft 14 and the second slide rod 16 on the second sleeve 15 can help realize the relative movement between the rotating shaft 14 and the second sleeve 15, thereby ensuring the accurate rotation of the sealing valve plate 13. This structural design is simple and reliable, and the flow rate of water passing through the second water hole 105 can be effectively controlled through the dynamic adjustment of the control component, making the operation of the filtration system more stable and efficient.

[0056] In some embodiments, a second through hole 106 is provided on the pipe wall of the main pipe 1, and the extension direction of the second through hole 106 is parallel to the axial direction of the main pipe 1 and is respectively connected to the sliding groove 103 and the second water hole 105, at least a portion of the second sleeve 15 is disposed in the sliding groove 103 and connected to the sliding portion 202 of the filter plate 2, and at least a portion of the rotating shaft 14 is disposed in the second through hole 106 and is rotatably matched with the second through hole 106.

[0057] For example, Figure 8 and Fig.10As shown, a portion of the second sleeve 15 is disposed in the sliding groove 103 and connected to the sliding portion 202 of the filter plate 2, thus saving space occupied by the main pipeline 1. A portion of the rotating shaft 14 is disposed in the second through hole 106 and rotatably cooperates with the second through hole 106, thus facilitating the arrangement and rotation of the rotating shaft 14, thereby facilitating the control of the rotation of the sealing valve plate 13 and realizing the opening and closing of the second water passage hole 105.

[0058] Optionally, the return spring 5 is sleeved in the sliding groove 103 and on the second sleeve 15 , and two ends of the return spring 5 are respectively stopped on the sliding portion 202 and the groove side wall of the sliding groove 103 .

[0059] For example, Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the function of the return spring 5 is to provide a certain preload force so that the filter plate 1 can maintain the stability of movement, thereby ensuring the stability of the sliding fit between the filter plate 2 and the main pipe 1. At the same time, when the filter plate 2 needs to move, the return spring 5 can provide a certain thrust so that the filter plate 2 can move smoothly. This design can improve the stability and reliability of the filtering operation.
