The first rotating shaft is located above the second rotating shaft; the upper end and the lower end of the filter are respectively mounted on the first rotating shaft and the second rotating shaft.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not 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.

[0029] An embodiment of an intelligent flood discharge and flow control device for a water conservancy project of the present invention is as follows: Figures 1 to 7 As shown, it includes a housing 100 , a filter 200 and a cleaning mechanism 300 .

[0030] The filter 200 is an annular belt structure and is rotatably installed on the housing 100 around an axis of a first axis, wherein the first axis is horizontal and perpendicular to the direction of water flow; the filter 200 is tilted and the upper end is located on the downstream side of the lower end, and the upper end of the filter 200 is located above the water surface; wherein the upper end and the lower end of the filter 200 are respectively two arc sections of the annular belt structure; when the filter 200 rotates, it drives the impurities on the water inlet side to move to the water outlet side of the filter 200.

[0031] A collection bin 110 is installed on the outer shell 100. The collection bin 110 is located on the water outlet side of the filter screen 200 and below the upper end of the filter screen 200, and is used to receive impurities that move to the water outlet side of the filter screen 200; since the filter screen 200 is arranged at an angle, the impurities intercepted by the filter screen 200 will fall into the collection bin 110 under the action of gravity when it rotates to the water outlet side of the upper end.

[0032] The outer shell 100 is also provided with a plurality of water baffles 120 distributed in sequence along the first axial direction. The plurality of water baffles 120 are respectively located on the water inlet side and the water outlet side of the filter net 200, and the water baffles 120 located on the water inlet side and the water outlet side of the filter net 200 are alternately distributed on the first axial direction, so as to block the water flow from directly passing through the filter net 200 along the water flow direction; specifically, after the water flow enters the filter net 200 from the water inlet side, it is blocked by the water baffle 120 located on the water outlet side, and then flows out from between the adjacent water baffles 120 located on the water outlet side.

[0033] The cleaning mechanism 300 is used to clean the impurities attached to the filter screen 200 .

[0034] By setting the filter screen 200 with an annular belt structure to intercept impurities, the impurities in the water can be continuously transported to the water outlet side when the filter screen 200 rotates, and the filter screen 200 is inclined, which is convenient for the impurities on the water inlet side to move with the filter screen 200, and also facilitates the impurities moved to the water outlet side to fall into the collection bin 110. In addition, by setting the water baffle 120, the water flow is prevented from directly passing through the filter screen 200 along the water flow direction, reducing the probability of impurities attached to the water outlet side of the filter screen 200 being washed away by the water flow, which can not only play a role in flow control, but also facilitate the cleaning mechanism 300 to clean the filter screen 200.

[0035] In this embodiment, a groove is provided at the bottom of the housing 100, and the lower end of the filter 200 is provided in the groove; the cleaning mechanism 300 includes an arc plate 310, which is located below the filter 200 and is coaxial with the arc segment of the lower end of the annular belt structure of the filter 200, and the arc plate 310 is installed in the groove in a radial sealing sliding manner along the first axial direction; the side of the arc plate 310 away from the filter 200 and the side wall of the groove define a collection chamber 330, and a water outlet 340 is provided on the collection chamber 330, and a filter and a first one-way valve are installed at the water outlet 340, and the first one-way valve allows water to flow outward from the collection chamber 330 in one direction. A second one-way valve is installed on the arc plate 310 to allow water flow and impurities to enter the collection chamber 330. When the arc plate 310 moves away from the filter 200, the space between the arc plate 310 and the filter 200 increases, and the filter 200 is sucked, so that the water inside the filter 200 flows outward, and the impurities attached to the outer surface of the filter 200 are separated from the filter 200; at the same time, the arc plate 310 squeezes the water in the collection chamber 330, and the water is filtered by the filter and discharged through the first one-way valve. When the arc plate 310 moves toward the filter 200, it squeezes the space between the arc plate 310 and the filter 200, and the impurities and water separated from the outer surface of the filter 200 enter the collection chamber 330 through the second one-way valve, so as to prevent the impurities from returning to the water inlet side of the filter 200 and affecting the interception efficiency of the filter 200. Through the reciprocating movement of the arc plate 310, impurities attached to the filter 200 are sucked and concentrated in the collection chamber 330; and the more frequently the arc plate 310 moves, the greater the disturbance to the impurities detached from the filter 200, and the easier it is for the impurities to enter the collection chamber 330 when the arc plate 310 moves toward the filter 200.

[0036] In some other embodiments, the collecting chamber 330 is provided with an openable and closable slag discharge port for an external discharge device to clean the impurities collected in the collecting chamber 330 .

[0037] In this embodiment, there are multiple water outlets 340, which are located on the water inlet side of the lower end of the filter net 200, and are used to spray water to the water inlet side of the filter net 200 to disperse impurities on the water inlet side, thereby avoiding uneven force on the filter net 200 due to uneven distribution of impurities, thereby affecting the service life of the filter net 200.

[0038] In this embodiment, an intelligent flood discharge and flow control device for water conservancy projects further includes a driving assembly 400, which is used to drive the filter screen 200 to rotate and the arc plate 310 to move. The driving assembly 400 includes a driving member 410, a first rotating shaft 420, and a second rotating shaft 430. The first rotating shaft 420 and the second rotating shaft 430 are both arranged along the first direction and are respectively rotatably installed on the housing 100 around their respective axes. The first rotating shaft 420 is located above the second rotating shaft 430. The upper end and the lower end of the filter screen 200 are respectively sleeved on the first rotating shaft 420 and the second rotating shaft 430. The driving member 410 drives the first rotating shaft 420 to rotate, thereby driving the filter screen 200 and the second rotating shaft 430 to rotate. Specifically, the driving member 410 is a motor, which drives the first rotating shaft 420 to rotate through a belt drive; the first rotating shaft 420 and the second rotating shaft 430 cooperate with the filter 200 through teeth and slots, that is, the outer circumference of the first rotating shaft 420 and the second rotating shaft 430 is provided with multiple slots, and the inner circle of the filter 200 is provided with teeth that cooperate with the slots.

[0039] In this embodiment, a cam 440 is mounted on the second rotating shaft 430, and when the second rotating shaft 430 rotates, the cam 440 pushes the arc plate 310 to move away from the filter 200; the cleaning mechanism 300 also includes an elastic member 320, which is arranged in the groove and is used to cause the arc plate 310 to move toward the filter 200 or have a tendency to move. Specifically, the cam 440 is eccentrically arranged relative to the second rotating shaft 430, and a push rod 311 is fixedly mounted on the arc plate 310, and the push rod 311 is used to contact with the cam 440, and the arc plate 310 is moved away from the filter 200 under the push of the cam 440; wherein, a circular groove for the rotation of the cam 440 and a sliding groove for the movement of the push rod 311 are arranged in the housing 100, and the circular groove is connected with the sliding groove. When the cam 440 rotates with the second rotating shaft 430 to be separated from the push rod 311 , the arc plate 310 moves toward the direction approaching the filter screen 200 under the action of the elastic member 320 .

[0040] In this embodiment, the arc plate 310 is coaxial with the second rotating shaft 430; a buffer arc segment is provided at the end of the outer circumference of the cam 440 that is farthest from the second rotating shaft 430, and the buffer arc segment is coaxial with the second rotating shaft 430. When the cam 440 rotates until the buffer arc segment abuts against the arc plate 310, the arc plate 310 remains stationary. By providing the buffer arc segment, when the arc plate 310 moves to the limit position where the collection chamber 330 is squeezed to the minimum, the arc plate 310 is made stationary for a period of time to ensure that the first one-way valve can be completely reset, and the arc plate 310 is prevented from resetting too quickly, and the first one-way valve is not able to reset in time, resulting in the external water being pumped from the water outlet 340 into the collection chamber 330, so that only the impurities and water between the arc plate 310 and the filter screen 200 can enter the collection chamber 330.

[0041] In this embodiment, hook teeth are provided on the outer surface of the filter 200 for picking up impurities in the water. The hook teeth may be arranged obliquely relative to the outer surface of the filter 200, and the end of the hook teeth away from the filter 200 is located at the front side of the end close to the filter 200 along the rotation direction of the filter 200; that is, the hook teeth located at the water inlet side of the filter 200 face upward relative to the filter 200, which is convenient for picking up impurities in the water, and the hook teeth located at the water outlet side of the filter 200 face downward relative to the filter 200, which is convenient for the picked up impurities to fall.

[0042] In this embodiment, an intelligent flood discharge flow control device for water conservancy projects further includes a flow control component 500, which includes a power component 510 and a partition 520, wherein the partition 520 is slidably mounted on the housing 100 and located on the water outlet side of the filter 200, and the partition 520 is located between two adjacent water retaining plates 120; the partition 520 moves under the drive of the power component 510, and is used to adjust the effective water outlet area on the water outlet side of the filter 200, thereby controlling the flow rate of the water flow. Among them, the power component 510 is a hydraulic cylinder.

[0043] When the intelligent flood discharge and flow control device for water conservancy projects of the present invention is in use, the upper end of the filter screen 200 is located above the water surface, and the water flows into the filter screen 200 from the water inlet side of the filter screen 200 and then flows out from the water outlet side of the filter screen 200. The water inlet side of the filter screen 200 intercepts impurities in the water, and rotates under the drive of the drive assembly 400 to transport the impurities to the water outlet side of the upper end of the filter screen 200. Later, due to the inclined setting of the filter screen 200, the impurities fall into the collection bin 110. After being blocked by the water baffle 120, the impurities on the water outlet side of the filter screen 200 are not easily washed away by the water flow. When the impurities attached to the filter screen 200 rotate to the lower end of the filter screen 200, they are sucked into the collection chamber 330 under the reciprocating movement of the arc plate 310, so as to realize the cleaning of the impurities attached to the filter screen 200.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
