Description

Technical Field

[0001] This application relates to the technical field of underwater water intake, and particularly relates to an underwater water intake chamber and a dredging process. Background Art

[0002] In the related art, there is an underwater water intake chamber, which includes a water intake chamber and a suction pipe. The water intake chamber is installed at the bottom of a river or a river. One end of the suction pipe is connected to the water intake chamber, and the other end of the suction pipe is connected to a refrigeration machine room. Filter screen plates are provided at both ends of the water intake chamber. The filter screen plates can preliminarily filter the river water to intercept suspended solids and coarse particulate matters in the raw water.

[0003] Regarding the above related art, the inventor believes that suspended solids and coarse particulate matters in the water may block the filter holes on the filter screen plates, resulting in a decrease in the pumping efficiency. Summary of the Invention

[0004] In order to reduce the probability of a decrease in pumping efficiency, this application provides an underwater water intake chamber and a dredging process.

[0005] An underwater water intake chamber provided by this application adopts the following technical solution:

[0006] An underwater water intake chamber includes a foundation, and the foundation is arranged at the bottom of the water; a water intake chamber, the water intake chamber includes a first filter plate and a second filter plate, the first filter plate and the second filter plate are both rotatably arranged on the foundation, the water intake chamber has an open state and a closed state. When the water intake chamber is in the open state, the first filter plate and the second filter plate are far away from each other and face the water flow direction. When the water intake chamber is in the closed state, the first filter plate and the second filter plate are in contact with each other and form a hemispherical shape. A water storage cavity is formed between the first filter plate and the second filter plate; a suction pipe, one end of the suction pipe is connected to the water intake chamber, and the other end of the suction pipe is connected to a refrigeration machine room. The suction pipe is used to transport the water in the water intake chamber into the refrigeration machine room; a fixing component, the fixing component includes a fixing driving part arranged on the foundation, a driving block arranged on the output shaft of the fixing driving part, a first guiding block arranged on the first filter plate, and a second guiding block arranged on the second filter plate. The first guiding block and the second guiding block are arranged oppositely, the driving block is arranged between the first guiding block and the second guiding block. Driven by the fixing driving part, the driving block drives the first guiding block and the second guiding block to move towards the side away from each other, thereby driving the first filter plate and the second filter plate to rotate towards the side away from each other.

[0007] By adopting the above technical solution, the fixed driving member drives the driving block to slide upward. Under the drive of the driving block, the first guiding block and the second guiding block move toward the side away from each other, so that the first filter plate and the second filter plate rotate toward the side away from each other. After the first filter plate and the second filter plate rotate to a certain extent, they rotate along with the flow direction of the water flow. When the first filter plate and the second filter plate rotate to face the water flow direction, the water flow flushes the first filter plate and the second filter plate, so as to wash the suspended matters and coarse particles in the water from the filter holes, reducing the risk of the filter holes being blocked, and thus reducing the probability of the pumping efficiency decreasing.

[0008] Optionally, a synchronous driving member is arranged on the foundation, and the synchronous driving member drives the first filter plate and the second filter plate to rotate toward the side away from each other or toward the side close to each other.

[0009] By adopting the above technical solution, the water flow may not be able to wash open the first filter plate and the second filter plate due to too slow flow rate, so that the first filter plate and the second filter plate cannot face the water flow direction, resulting in insufficient cleaning of the first filter plate and the second filter plate by the water flow. By setting the synchronous driving member in this solution, the synchronous driving member drives the first filter plate and the second filter plate to rotate toward the side away from each other or toward the side close to each other, reducing the risk that the first filter plate and the second filter plate cannot face the water flow, and making the cleaning of the first filter plate and the second filter plate by the water flow more stable.

[0010] Optionally, it further includes a first positioning assembly for fixing the first filter plate and a second positioning assembly for fixing the second filter plate. The first positioning assembly includes a first positioning block and a first elastic member. A first sliding groove is formed at one end of the first guiding block close to the driving block. The first positioning block is slidably inserted into the first sliding groove. A first positioning groove opposite to the first sliding groove is arranged on the driving block. The first elastic member is arranged between the first positioning block and the bottom of the first sliding groove. The first elastic member presses the first positioning block partially into the first positioning groove. The second positioning assembly includes a second positioning block and a second elastic member. A second sliding groove is formed at one end of the second guiding block close to the driving block. The second positioning block is slidably inserted into the second sliding groove. A second positioning groove opposite to the second sliding groove is arranged on the driving block. The second elastic member is arranged between the second positioning block and the bottom of the second sliding groove. The second elastic member presses the second positioning block partially into the second positioning groove.

[0011] By adopting the above technical solution, there is a risk that the first filter plate and the second filter plate may rotate due to being washed by water flow. This solution limits the first filter plate by setting a first positioning component and a second positioning component. Part of the first positioning block is located in the first chute, and the other part of the first positioning block is located in the first positioning groove, thereby reducing the risk of the first filter plate being washed open by the flowing water. Part of the second positioning block is located in the second chute, and the other part of the second positioning block is located in the second positioning groove, thereby limiting the second filter plate and reducing the risk of the second filter plate being washed open by the flowing water.

[0012] Optionally, a first guiding surface is provided at one end of the first positioning block away from the first elastic member. The first guiding surface is inclined in the direction in which the driving block is inserted. A second guiding surface is provided at one end of the second positioning block away from the second elastic member. The second guiding surface is inclined in the direction in which the driving block is inserted.

[0013] By adopting the above technical solution, when the driving block moves upward and abuts against the first guiding surface and the second guiding surface, since the first chute restricts the first positioning block to slide only along the length direction of the first chute, and the second chute restricts the second positioning block to slide only along the length direction of the second chute, the first positioning block slides into the first chute, and the second positioning block slides into the second chute. When the driving block moves to a position where the first positioning groove is opposite to the first chute, part of the first positioning block slides into the first positioning groove. When the second positioning groove is aligned with the second chute, part of the second positioning block slides into the second positioning groove, which facilitates the fixing of the first filter plate and the second filter plate.

[0014] Optionally, it further includes a water spraying component. The water spraying component includes a water spraying head and a connecting pipe. The water spraying head is installed on the foundation, and when the first filter plate is in an open state, the water spraying head is directly opposite to the first filter plate / the second filter plate. One end of the connecting pipe is connected to the water extraction pipe, and the other end of the connecting pipe is connected to the water spraying head.

[0015] By adopting the above technical solution, part of the water in the water extraction pipe enters the connecting pipe, and then is transported by the connecting pipe to the water spraying head. The water sprays out from the water spraying head to wash the first filter plate and the second filter plate. The water in the connecting pipe and the water in the river collide with each other to form agitation, cleaning the filter holes of the first filter plate and the second filter plate, and improving the cleaning effect on the first filter plate and the second filter plate.

[0016] Optionally, a plurality of water spraying heads are provided, and the plurality of water spraying heads are arranged at intervals along the length direction of the first filter plate / the second filter plate.

[0017] By adopting the above technical solution, a plurality of water spray heads are arranged at intervals along the length directions of the first filter plate and the second filter plate, so as to clean the first filter plate and the second filter plate more comprehensively, and improve the cleaning effect on the first filter plate and the second filter plate.

[0018] Optionally, a water filtering chamber is arranged in the water storage chamber of the water intake chamber, and water filtering plates are arranged at both ends of the water filtering chamber, and both of the two water filtering plates are arranged facing the water flow direction.

[0019] By adopting the above technical solution, when the first filter plate and the second filter plate are opened, water flow may flow into the water suction pipe, resulting in suspended matters and coarse particles in the water entering the refrigeration machine room and affecting the heat exchange. This solution sets up a water filtering chamber, and water filtering plates are arranged at both ends of the water filtering chamber. The water filtering plates can perform secondary filtration on the water flow, increasing the filtration accuracy, and still filtering the water flow while cleaning the first filter plate and the second filter plate.

[0020] Optionally, it further includes a cleaning component. The cleaning component includes a rotating plate which is rotatably arranged on the foundation. A plurality of inserting columns are arranged on the rotating plate. When the rotating plate rotates to be perpendicular to the foundation, the inserting columns are inserted into the filter holes of the water filtering plate.

[0021] By adopting the above technical solution, when the water filtering plate needs to be cleaned, rotate the rotating plate until it is perpendicular to the foundation. A plurality of the inserting columns on the rotating plate are inserted into the filter holes of the water filtering plate, so as to eject the suspended matters and coarse particles adhering to the filter holes of the water filtering plate, reducing the risk of the water filtering plate being blocked.

[0022] Optionally, bristles are arranged on the peripheral side wall of the inserting column.

[0023] By adopting the above technical solution, the bristles can clean the filter holes of the water filtering plate well, improving the cleaning effect on the water filtering plate.

[0024] In a second aspect, the present application provides a dredging process, adopting the following technical solution:

[0025] Step S1: Start the fixed driving part. The driving block slides upward under the drive of the fixed driving part. The driving block drives the first guiding block and the second guiding block to move away from each other, so that the first filter plate and the second filter plate rotate to an open part.

[0026] Step S2: Start the synchronous driving part. The synchronous driving part drives the first filter plate and the second filter plate to rotate away from each other, so that the first filter plate and the second filter plate face the water flow direction, and the water flow flushes the first filter plate and the second filter plate to wash away the suspended matters and coarse particles.

[0027] By adopting the above technical solution, the fixed driving member rotates the first filter plate and the second filter plate to the side away from each other. When the first filter plate and the second filter plate rotate to a certain angle, the water flow impacts the first filter plate and the second filter plate, driving the first filter plate and the second filter plate to rotate. When the first filter plate and the second filter plate rotate to face the water flow direction, the water flow scours the first filter plate and the second filter plate, washing away suspended matter and coarse particulate matter.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. By providing the first filter plate, the second filter plate and the fixing assembly, both the first filter plate and the second filter plate are rotatably connected to the foundation. The fixed driving member drives the driving block to move upward, and the driving block drives the first filter plate and the second filter plate to rotate to the side away from each other. The water flow drives the first filter plate and the second filter plate to rotate, so that the first filter plate and the second filter plate face the water flow direction for scouring, reducing the risk of the filter holes being blocked, and thus reducing the probability of the pumping efficiency decreasing;

[0030] 2. By providing the water spraying assembly, the spray head cleans the first filter plate and the second filter plate, and the water sprayed by the spray head impacts the water in the river, forming agitation, cleaning the filter holes of the first filter plate and the second filter plate, and improving the cleaning effect on the first filter plate and the second filter plate;

[0031] 3. By providing the water filtering chamber, when the water intake chamber is being cleaned, the water filtering chamber can still filter the water, and the water filtering chamber can perform secondary filtering on the water, improving the filtering effect. Description of the Drawings

Detailed implementation manners

[0042] The following further elaborates on this application in conjunction with the attached Figure 1-7 drawings for a more detailed description.

[0043] An embodiment of this application discloses an underwater water intake chamber. Referring to Figure 1 , the underwater water intake chamber includes a foundation 1 built on the bottom of the water, a water intake chamber 2 installed on the top wall of the foundation 1 away from the bottom of the water and used for filtering water sources, and a water extraction pipe 3 arranged on the side wall of the foundation 1 and used for conveying the water in the water intake chamber 2 into the refrigeration machine room.

[0044] The water intake chamber 2 is hemispherical. The water intake chamber 2 includes a first filter plate 21 and a second filter plate 22. The first filter plate 21 and the second filter plate 22 are arranged opposite to each other, and both the first filter plate 21 and the second filter plate 22 are rotatably connected to the foundation 1. The water intake chamber 2 has a closed state and an open state.

[0045] Referring to Figure 1 and Figure 2 , when the water intake chamber 2 is in the closed state, the first filter plate 21 and the second filter plate 22 are in contact with each other and are hemispherical, and a water storage cavity 23 for storing water is formed inside. The river water enters the water storage cavity 23 after being filtered by the first filter plate 21 and the second filter plate 22.

[0046] When the water intake chamber 2 is in the open state, the first filter plate 21 and the second filter plate 22 rotate towards the side away from each other, and the water storage chambers 23 of the first filter plate 21 and the second filter plate 22 face the water flow direction. The water flow can wash the first filter plate 21 and the second filter plate 22, washing off the suspended matters and coarse particles on the first filter plate 21 and the second filter plate 22, reducing the risk of the filter holes being blocked.

[0047] The underwater water intake chamber further includes a fixing component 5, and the fixing component 5 is used to fix the first filter plate 21 and the second filter plate 22, so that the first filter plate 21 and the second filter plate 22 are kept in the closed state.

[0048] Refer to Figure 3 and Figure 4 As shown in FIGS. and, the fixing component 5 includes a fixing driving member 54, a driving block 53, a first guiding block 51 and a second guiding block 52. A first installation groove 11 for installing the fixing driving member 54 is formed on the top wall of the foundation 1 away from the bottom of the water. For example, the fixing driving member 54 is installed in the first installation groove 11 by bolts. In this embodiment, the fixing driving member 54 is preferably set as an electric cylinder.

[0049] The driving block 53 is trapezoidal. In this embodiment, the end of the driving block 53 close to the bottom of the water is the long side of the trapezoid, and the end of the driving block 53 away from the bottom of the water is the short side of the trapezoid. The driving block 53 is threadedly connected to the telescopic rod of the fixing driving member 54, and the driving member can drive the driving block 53 to slide vertically back and forth.

[0050] Refer to Figure 4 As shown in FIGS., the first guiding block 51 is installed on the side wall of the water storage chamber 23 of the first filter plate 21. For example, the first guiding block 51 is installed on the first filter plate 21 by bolts. The second guiding block 52 is installed on the side wall of the water storage chamber 23 of the second filter plate 22. For example, the second guiding block 52 is installed on the second filter plate 22 by bolts. The first guiding block 51 and the second guiding block 52 are arranged oppositely. The driving block 53 is located between the first guiding block 51 and the second guiding block 52.

[0051] One end of the first guiding block 51 close to the second guiding block 52 is provided with a first inclined surface 511 abutting against the inclined side wall of the driving block 53, and one end of the second guiding block 52 close to the first guiding block 51 is provided with a second inclined surface 521 abutting against the other inclined side wall of the driving block 53.

[0052] The fixed driving member 54 drives the driving block 53 to slide upward. Since the two inclined side walls of the driving block 53 are respectively abutted against the first inclined surface 511 and the second inclined surface 521, during the upward movement of the driving block 53, the first guiding block 51 and the second guiding block 52 move away from each other, so that the first filter plate 21 and the second filter plate 22 rotate away from each other.

[0053] Refer to Figure 5 , the underwater water intake chamber further includes a rotating assembly 8, which drives the first filter plate 21 and the second filter plate 22 to rotate away from each other or drives the first filter plate 21 and the second filter plate 22 to rotate towards each other through the rotating assembly 8.

[0054] The rotating assembly 8 includes a first rotating shaft 83, a second rotating shaft 84, a first rotating block 81 and a second rotating block 82. The first rotating block 81 is integrally arranged on the outer side wall of the first filter plate 21. A first fixing groove 811 for vertically inserting the first rotating shaft 83 is formed on the side of the first rotating block 81 close to the foundation 1. The first rotating block 81 and the first rotating shaft 83 are connected by a key, and the first filter plate 21 is rotatably connected to the foundation 1 through a rotating shaft. By rotating the first rotating block 81, the first filter plate 21 can be driven to rotate circumferentially along the axis of the first rotating shaft 83.

[0055] The second rotating block 82 is integrally arranged on the outer side wall of the second filter plate 22. A second fixing groove 821 for vertically inserting the second rotating shaft 84 is formed on the side of the second rotating block 82 close to the foundation 1. The second rotating block 82 and the second rotating shaft 84 are connected by a key, and the first filter plate 21 is rotatably connected to the foundation 1 through a rotating shaft. By rotating the second rotating block 82, the second filter plate 22 can be driven to rotate circumferentially along the axis of the second rotating shaft 84.

[0056] Refer to Figure 5, the underwater intake chamber further includes a synchronization component 9, which includes a first gear 92, a second gear 93, and a synchronization driving member 91. The first gear 92 is coaxially sleeved on one end of the first rotating shaft 83 away from the foundation 1, and the second gear 93 is coaxially sleeved on one end of the second rotating shaft 84 away from the foundation 1, and the first gear 92 and the second gear 93 mesh with each other. A second installation groove 12 for installing the synchronization driving member 91 is formed on the foundation 1. For example, the synchronization driving member 91 is installed in the second installation groove 12 by bolts. In this embodiment, the synchronization driving member 91 is preferably set as a motor. The output shaft of the synchronization driving member 91 and the first rotating shaft 83 are connected by a key. The synchronization driving member 91 drives the first rotating shaft 83 to rotate through the output shaft, and the first rotating shaft 83 drives the first filter plate 21 to rotate circumferentially around the axis of the first rotating shaft 83. Since the second gear 93 and the first gear 92 mesh with each other, the second gear 93 drives the second rotating shaft 84 to rotate, and the second rotating shaft 84 drives the second filter plate 22 to rotate circumferentially around the axis of the second rotating shaft 84, thereby realizing the synchronous rotation towards each other or away from each other of the first filter plate 21 and the second filter plate 22.

[0057] Referring to Figure 4 , the underwater intake chamber further includes a first positioning component 6 for fixing the first filter plate 21 and a second positioning component 7 for fixing the second filter plate 22.

[0058] The first positioning component 6 includes a first positioning block 61 and a first elastic member 62. A first sliding groove 512 for the first positioning block 61 to slide is vertically formed on one side of the first guiding block 51 close to the driving block 53, and a first positioning groove 531 opposite to the first sliding groove 512 is formed on one side of the driving block 53 close to the first guiding block 51. In this embodiment, the first elastic member 62 is preferably set as a compression spring. The first elastic member 62 is arranged between the first positioning block 61 and the bottom of the first sliding groove 512, and the first elastic member 62 presses a part of the first positioning block 61 into the first positioning groove 531. A part of the first positioning block 61 is located in the first sliding groove 512, and the other part of the first positioning block 61 is located in the first positioning groove 531. When the first filter plate 21 rotates, the side wall of the first positioning block 61 abuts against the side wall of the first positioning groove 531, thereby restricting the rotation of the first filter plate 21 and fixing the first filter plate 21.

[0059] The second positioning component 7 includes a second positioning block 71 and a second elastic member 72. A second sliding groove 522 for the second positioning block 71 to slide is vertically formed on one side of the second guiding block 52 close to the driving block 53, and a second positioning groove 532 opposite to the second sliding groove 522 is formed on one side of the driving block 53 close to the second guiding block 52. In this embodiment, the second elastic member 72 is preferably arranged as a compression spring. The second elastic member 72 is arranged between the second positioning block 71 and the bottom of the second sliding groove 522, and the second elastic member 72 presses part of the second positioning block 71 into the second positioning groove 532. Part of the second positioning block 71 is located in the second sliding groove 522, and the other part of the second positioning block 71 is located in the second positioning groove 532. When the second filter plate 22 rotates, the side wall of the second positioning block 71 abuts against the wall of the second positioning groove 532, thereby restricting the rotation of the second filter plate 22 and fixing the second filter plate 22.

[0060] The first filter plate 21 and the second filter plate 22 are kept in a closed state by the first positioning component 6 and the second positioning component 7.

[0061] Refer to Figure 4 , one end of the first positioning block 61 away from the first elastic member 62 is provided with a first guiding surface 611, and the first guiding surface 611 is gradually inclined and arranged from the side close to the foundation 1 to the side away from the foundation 1. One end of the second positioning block 71 away from the second elastic member 72 is provided with a second guiding surface 711, and the second guiding surface 711 is gradually inclined and arranged from the side close to the foundation 1 to the side away from the foundation 1.

[0062] When the driving block 53 moves to the side away from the foundation 1, the side wall of the first positioning groove 531 close to the foundation 1 abuts against the first guiding surface 611. Since the first sliding groove 512 restricts the first positioning block 61 to move only along the length direction of the first positioning groove 531, the first positioning block 61 completely slides into the first sliding groove 512. The side wall of the second positioning groove 532 close to the foundation 1 abuts against the second guiding surface 711. Since the second sliding groove 522 restricts the second positioning block 71 to move only along the length direction of the second positioning groove 532, the second positioning block 71 completely slides into the second sliding groove 522. At this time, the first positioning block 61 does not limit the first filter plate 21, and the second positioning block 71 does not limit the second filter plate 22. The driving block 53 drives the first guiding block 51 and the second guiding block 52 to move away from each other, thereby driving the first filter plate 21 and the second filter plate 22 to rotate away from each other, facilitating the opening of the first filter plate 21 and the second filter plate 22.

[0063] Refer to Figure 5, a flow velocity detector 211 is installed at the top of the first filter plate 21 away from the foundation 1, and a storage battery 13 is arranged at the top of the foundation 1 away from the bottom of the water. The flow velocity detector 211 and the storage battery 13 are electrically connected. The flow velocity detector 211 and the fixed driving member 54 are electrically connected, and the water flow detector and the synchronous driving member 91 are electrically connected. When the flow velocity detector 211 detects that the flow velocity at the bottom of the water reaches a certain range, it sends a signal to the fixed driving member 54 and the synchronous driving member 91. The fixed driving member 54 drives the driving block 53 to move upward, so that the first filter plate 21 and the second filter plate 22 rotate to the side away from each other. When the first filter plate 21 and the second filter plate 22 rotate to a certain angle, the synchronous driving member 91 drives the first filter plate 21 and the second filter plate 22 to rotate to the side away from each other until the first filter plate 21 and the second filter plate 22 rotate to face the water flow direction.

[0064] When the flow velocity detector 211 detects that the flow velocity at the bottom of the water decreases to a certain range, it sends a signal to the synchronous driving member 91 and the fixed driving member 54. The output shaft of the fixed driving member 54 retracts until the driving block 53 is located below the first guiding block 51 and the second guiding block 52. The synchronous driving member 91 drives the first filter plate 21 and the second filter plate 22 to move towards the side close to each other. When the first filter plate 21 and the second filter plate 22 are in contact with each other, the fixed driving member 54 drives the driving block 53 to move upward, pressing the first positioning block 61 into the first sliding groove 512 and the second positioning block 71 into the second sliding groove 522. When the first sliding groove 512 and the first positioning groove 531 are opposite, part of the first positioning block 61 is pressed into the first positioning groove 531 by the first elastic member 62, and part of the second positioning block 71 is pressed into the second positioning groove 532 by the first elastic member 62, so that the first filter plate 21 and the second filter plate 22 are kept in a closed state.

[0065] The underwater water intake chamber further includes a water spraying assembly 31 for flushing the water intake chamber 2. The water spraying assembly 31 includes a connecting pipe 311 and a plurality of water spraying heads 312. When the water intake chamber 2 is in an open state, the connecting pipe 311 is located below the first filter plate 21 and the second filter plate 22. The connecting pipe 311 extends along the length direction of the first filter plate 21 and the second filter plate 22. One end of the connecting pipe 311 is connected to the water extraction pipe 3. The water spraying heads 312 are installed on the side of the connecting pipe 311 close to the first filter plate 21 / the second filter plate 22, and the plurality of water spraying heads 312 are evenly spaced along the length direction of the connecting pipe 311.

[0066] When the water extraction pipe 3 pumps water, part of the water flow flows into the connecting pipe 311 and flows out from the openings of the plurality of water spraying heads 312. The water flowing out flushes the first filter plate 21 and the second filter plate 22. The water in the connecting pipe 311 and the water in the river impact each other to form agitation, cleaning the filter holes of the first filter plate 21 and the second filter plate 22, and improving the cleaning effect on the first filter plate 21 and the second filter plate 22.

[0067] Referring to Figure 6 , a water intake chamber 2 is provided with a water filtering chamber 4 in a water storage cavity 23. The water filtering chamber 4 is square. Filter plates 41 are provided at both ends of the water filtering chamber 4, and the two filter plates 41 are arranged facing the water flow direction. The filter plates 41 can perform secondary filtration on the water flow, increasing the filtration accuracy, and can still filter the water flow while the first filter plate 21 and the second filter plate 22 are being cleaned.

[0068] The underwater water intake chamber further includes two sets of cleaning components 10 for cleaning the filter plates 41. The two sets of cleaning components 10 are arranged in the water filtering chamber 4 and are oppositely arranged.

[0069] The cleaning component 10 includes a rotating plate 101 and a cleaning driving member 102. Rotating holes 42 are formed in both inner walls of the water filtering chamber 4, and the rotating holes 42 penetrate through to the outer side wall of the water filtering chamber 4. The rotating plate 101 is rotatably connected to the rotating holes 42 through a rotating shaft. The cleaning driving member 102 is installed on the foundation 1. In this embodiment, the cleaning driving member 102 is preferably set as a motor. The output shaft of the cleaning driving member 102 and the rotating shaft of the rotating plate 101 are connected by a key. The cleaning driving member 102 drives the rotating plate 101 to rotate circumferentially along the axis of the rotating shaft.

[0070] Referring to Figure 7 and Figure 8 , a plurality of insertion posts 1011 corresponding to the filter holes on the filter plate 41 are integrally provided on the side wall of the rotating plate 101 away from the foundation 1. The diameter of the insertion posts 1011 is smaller than the diameter of the filter holes of the filter plate 41. A plurality of bristles 10111 are provided on the circumferential side wall of the insertion posts 1011.

[0071] By driving the rotating plate 101 to rotate to face the filter plate 41 through the cleaning driving member 102, the insertion posts 1011 are inserted into the filter holes of the water in the filter holes, and the bristles 10111 clean the filter holes, brushing off the suspended matters and coarse particles in the filter holes.

[0072] The implementation principle of an underwater water intake chamber in an embodiment of the present application is as follows: When the water flow detector detects that the water flow increases to a certain range, the water flow detector sends a signal to the fixed driving member 54. The fixed driving member 54 drives the driving block 53 to move upward, driving the first guiding block 51 and the second guiding block 52 to rotate towards the side away from each other, and the first filter plate 21 and the second filter plate 22 to rotate towards the side away from each other. When the first filter plate 21 and the second filter plate 22 rotate to a certain angle, the synchronous driving member 91 drives the first filter plate 21 and the second filter plate 22 to rotate towards the side away from each other until the first filter plate 21 and the second filter plate 22 are facing the water flow direction. At this time, the flowing water flushes the first filter plate 21 and the second filter plate 22, washing off the suspended matter and coarse particles on the first filter plate 21 and the second filter plate 22, reducing the risk of the filter holes being blocked. The cleaning driving member 102 rotates, driving the rotating plate 101 to rotate until it faces the water filtering plate 41. The plug posts 1011 on the rotating plate 101 are inserted into the corresponding filter holes, and the bristles 10111 on the circumferential side wall of the plug posts 1011 clean the filter holes, brushing off the suspended matter and coarse particles in the filter holes.

[0073] When the water flow detector detects that the water flow decreases to a certain range, the water flow detector sends a signal to the fixed driving member 54. The output shaft of the fixed driving member 54 retracts until the driving block 53 is located below the first guiding block 51 and the second guiding block 52. The synchronous driving member 91 drives the first filter plate 21 and the second filter plate 22 to move towards the side close to each other. When the first filter plate 21 and the second filter plate 22 are in contact with each other, the fixed driving member 54 drives the driving block 53 to move upward, pressing the first positioning block 61 into the first sliding groove 512 and the second positioning block 71 into the second sliding groove 522. When the first sliding groove 512 and the first positioning groove 531 are opposite, a part of the first positioning block 61 is pressed into the first positioning groove 531 by the first elastic member 62, and a part of the second positioning block 71 is pressed into the second positioning groove 532 by the first elastic member 62, so that the first filter plate 21 and the second filter plate 22 remain in a closed state.

[0074] An embodiment of the present application also discloses a dredging process.

[0075] Start the fixed driving member 54. The fixed driving member 54 drives the driving block 53 to slide upward. The driving block 53 drives the first guiding block 51 and the second guiding block 52 to move towards the side away from each other, causing the first filter plate 21 and the second filter plate 22 to rotate towards the side away from each other.

[0076] Start the synchronous driving member 91. The synchronous driving member 91 drives the first filter plate 21 and the second filter plate 22 to move towards the side away from each other until the first filter plate 21 and the second filter plate 22 are facing the water flow direction, and the water flushes the first filter plate 21 and the second filter plate 22, washing off the suspended matter and coarse particles.

[0077] Start the cleaning driving member 102. The cleaning driving member 102 drives the rotating plate 101 to rotate until it faces the water filtering plate 41. The inserting posts 1011 on the rotating plate 101 are inserted into the filtering holes of the water filtering plate 41, and the bristles 10111 on the peripheral wall of the inserting posts 1011 clean the filtering holes of the water filtering plate 41.

[0078] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
