[0002] Wastewater filtration in water conservancy projects refers to the process of intercepting and removing suspended debris, floating objects, etc. in water bodies through specific devices or systems in water conservancy facilities. Its main purpose is to ensure the smooth flow of water, protect the ecological environment of water bodies, and prevent debris from clogging and damaging water conservancy equipment. Therefore, sewage filtration is crucial in water conservancy projects. It can not only improve the operating efficiency of waterways, but also effectively reduce the negative impact of water bodies on downstream ecosystems.

[0003] Existing water conservancy project sewage filtration usually relies on various types of trash racks and manual cleaning methods. Fixed fences or grating structures are installed in waterways to block floating objects and suspended debris on the water surface.

DETAILED DESCRIPTION

[0028] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0029] Example 1: Existing sewage filtration in water conservancy projects usually relies on various types of trash racks and manual cleaning methods. Fixed fences or grating structures are installed in waterways to block floating objects and suspended debris on the water surface. In most cases, subsequent cleaning still relies mainly on manual operations, with a low degree of automation. In addition, existing trash racks usually target larger floating objects and cannot effectively filter smaller suspended debris, resulting in fine impurities remaining in the water flow, making it impossible to achieve all-round filtration and cleaning of larger floating objects, smaller suspended debris and silt in the water body.

[0030] In view of the above problems, the present embodiment provides a sewage filtration device for a water conservancy project, which aims to utilize the coordinated cooperation of a special-shaped debris screen 1 and a rotating filter screen 2 to filter and collect large-area debris floating in the water; filter fine suspended debris in the water through an auxiliary filter net 5; and clear the sediment at the bottom of the water through a sediment treatment component; thereby achieving all-round filtration and cleaning of the water body through the coordinated action of various components.

[0031] like Figure 1-3 As shown, the debris intercepting mechanism includes a special-shaped debris intercepting screen 1 and a rotating filter screen 2. The special-shaped debris intercepting screen 1 is fixedly installed in the waterway 9, and a convex arc portion 11 and a concave arc portion 12 are provided on the top thereof. A leak-proof groove 13 is provided below the concave arc portion 12 to prevent the debris filtered and collected by the rotating filter screen 2 from entering the water flow for the second time.

[0032] The rotating filter screen 2 is installed on the inner side of the special-shaped debris screen 1. The rotating filter screen 2 consists of a rotating rod 21 and a plurality of cleaning vertical rods 23. The rotating rod 21 is rotatably mounted in the waterway 9. Both ends of the rotating rod 21 are rotatably mounted in the waterway 9 through a rotating shaft, and the rotating shaft of the rotating rod 21 extends out of the waterway 9. Matching holes 22 corresponding to each cleaning vertical rod 23 are radially penetrated on the rotating rod 21. The cleaning vertical rod 23 is slidably mounted in the matching holes 22, or the diameter of the matching holes 22 is larger than the diameter of the cleaning vertical rod 23. The cleaning vertical rod 23 is penetrated in the matching holes 22. The cleaning vertical rod 23 corresponds to the gap between adjacent railings in the special-shaped debris screen 1. When the rotating rod 21 rotates to drive the cleaning vertical rod 23, the cleaning vertical rod 23 can pass through the gap between adjacent railings in the special-shaped debris screen 1.

[0033] A counterweight body 231 is fixedly mounted on the top and bottom of the cleaning vertical rod 23 , respectively, and an auxiliary hook plate 232 is also arranged on the top and bottom of the cleaning vertical rod 23 . The auxiliary hook plate 232 is made of a light material.

[0034] The driving assembly 8 is used to drive the rotating rod 21 to rotate counterclockwise. The driving assembly 8 includes a worm wheel 81, a worm 82 and a driving motor 83. The worm wheel 81 is fixedly mounted on the rotating shaft, the worm 82 is transmission-connected to the output shaft of the driving motor 83, and the worm 82 is meshed with the worm wheel 81. The motor seat of the driving motor 83 is installed on the outer side of the waterway 9, and a worm 82 frame is installed on the motor seat. The worm 82 is rotatably mounted in the worm 82 frame.

[0035] like Figure 4-7As shown, the locking unit 3 includes a guide locking seat 31, a locking sleeve 32, a guide sleeve 33 and a follower push rod 34. The guide locking seat 31 is fixedly installed on the side of the rotating rod 21 and corresponds to the matching hole 22 of the rotating rod 21. The cleaning vertical rod 23 is guided and slidably sleeved in the guide locking seat 31. The cleaning vertical rod 23 can only slide axially in the guide locking seat 31 and will not rotate. That is, the cleaning vertical rod 23 is freely axially slidable and sleeved in the guide locking seat 31 and the rotating rod 21; the guide sleeve 33 is transversely installed in the guide locking seat 31. 1, the follower push rod 34 is coaxially slidably sleeved in the guide sleeve 33, and the adjacent follower push rods 34 on the rotating rod 21 are connected as a whole through the connecting rod 35, the locking sleeve 32 is arranged in the guide locking seat 31, the inner end of the follower push rod 34 is fixedly connected with the locking sleeve 32 located in the guide locking seat 31, and the follower push rod 34 is provided with a spline, and a spline groove is opened in the guide sleeve 33, and the spline of the follower push rod 34 is sleeved in the spline groove, so that the follower push rod 34 can slide axially in the guide sleeve 33.

[0036] The cleaning vertical rod 23 is located in the locking sleeve 32, and there is a matching gap between the cleaning vertical rod 23 and the locking sleeve 32. Figure 4-5 As shown, a conical clamping rod 36 is provided in the locking sleeve 32, and the conical clamping rod 36 is staggered up and down on both sides of the interior of the locking sleeve 32. A conical clamping groove 37 corresponding to the conical clamping rod 36 is provided on the cleaning vertical rod 23. The conical clamping groove 37 is arranged on the outer peripheral side of the cleaning vertical rod 23, and the conical clamping groove 37 corresponds to the conical clamping rod 36. The follower push rod 34 pushes the locking sleeve 32 to enable the conical clamping rod 36 to be clamped in the conical clamping groove 37, thereby locking the cleaning vertical rod 23.

[0037] like Figure 4-7 As shown, the pendulum control unit 4 includes a pendulum body 41, a strut group and a hanging rope, the strut group includes an upper strut 42 and a lower strut 43, the upper strut 42 and the lower strut 43 are respectively connected to the guide locking seat 31 and the rotating rod 21 along the horizontal direction, and the upper strut 42 corresponds to the lower strut 43 up and down, the hanging rope includes an upper hanging rope 44 and a lower hanging rope 45, the pendulum body 41 is connected to the upper strut 42 through the upper hanging rope 44, the pendulum body 41 is connected to the lower strut 43 through the lower hanging rope 45, and the lower hanging rope 45 is in a relaxed state, the pendulum movement of the pendulum body 41 can drive the follow-up push rod 34 to control the locking and release of the cleaning vertical rod 23.

[0038] An auxiliary filter screen 5 is fixedly installed at the rear end of the special-shaped debris barrier 1, and vertical tracks 51 are installed on both sides of the auxiliary filter screen 5. The slide bar 53 is slidably inserted into the vertical track 51 through the slider 52, so that the slide bar 53 can slide up and down in the vertical track 51 through the slider 52; the auxiliary filter screen 5 can further filter and intercept fine suspended debris.

[0039] like Figure 2 , Figure 9-11As shown, the brush assembly 6 includes a brush frame 61, a brush body 66 and a float 67. A pressure plate 64 is installed on the brush frame 61. The brush frame 61 includes a hinged rod 1 62, a hinged rod 2 63 and a ring sleeve 64. The hinged rod is hinged to the ring sleeve 64, and the ring sleeve 64 is slidably mounted on the railing of the special-shaped debris barrier 1. The hinged rod 1 62 and the hinged rod 2 63 are hinged by a hinged horizontal axis 65, and a torsion spring is also installed between the hinged rod 1 62 and the hinged rod 2 63, and the distal end of the hinged rod 2 63 is hinged to the brush body 66. The hinged rod 1 62, the hinged rod 2 63 and the ring sleeve 64 are all provided in plurality, and are combined to form the brush frame 61. A flat hole 68 is opened through the brush body 66, and the brush body 66 is mounted on the slide rod 53 through the flat hole 68. The float 67 is fixedly installed at the bottom of the brush body 66; as shown Figure 3 As shown, in the initial state, the scrubbing frame 61 is pressed down by the deadweight of the cleaning vertical rod 23. When the cleaning vertical rod 23 is driven by the rotating rod 21, the cleaning vertical rod 23 will separate from the pressure plate 64 of the scrubbing frame 61 and no longer press the pressure plate 64. At this time, the scrubbing frame 61 can float upward under the action of the float 67. When one end of the cleaning vertical rod 23 is rotated to the top of the special-shaped debris barrier 1 (that is, it is in a vertical state), the cleaning vertical rod 23 will slide downward by its own weight under the action of the gravity of the counterweight body 231 and reset to the initial state. In the process of the cleaning vertical rod 23 sliding downward by its own weight, the downward action of the cleaning vertical rod 23 will synchronously press the scrubbing frame 61 downward through the pressure plate 64 to scrub and scrape away the fine debris on the auxiliary filter screen 5.

[0040] When the brush frame 61 is pressed down by the weight of the cleaning vertical rod 23, the brush frame 61 is pressed to a horizontally unfolded state, the hinge rod 1 62 and the hinge rod 2 63 are in a horizontal state, and the brush body 66 is pushed by the hinge rod 2 63, and the brush body 66 moves forward on the slide rod 53 through the flat hole 68 and fits with the auxiliary filter 5 to achieve brushing of the auxiliary filter 5; When the cleaning vertical rod 23 is separated from the brush frame 61, the entire brush frame 61 will move upward under the buoyancy of the float 67. At the same time, under the action of the torsion spring, the hinged rod 1 62 and the hinged rod 2 63 are in a bent and contracted state, and the brush body 66 will be pulled by the hinged rod. The brush body 66 moves backward on the slide rod 53 through the flat hole 68 and separates from the auxiliary filter screen 5.

[0041] The sediment processing assembly includes a sediment pipe 7 installed at the bottom of the front side of the auxiliary filter screen 5. The sediment pipe 7 is connected to an external sediment pump. The sediment deposited in the waterway 9 can be cleaned through the sediment pipe 7, and the sediment pipe 7 can also suck and clean the fine suspended debris brushed off the auxiliary filter screen 5 by the brush body 66.

[0042] In the initial state, if Figure 2-3As shown, the cleaning vertical rod 23 is in a vertical state, the pendulum body 41 is also in a vertical state, the locking sleeve 32 does not lock the cleaning vertical rod 23, the driving assembly 8 drives the rotating rod 21 to rotate counterclockwise, and the rotating speed of the rotating rod 21 is slow; When the rotating rod 21 rotates counterclockwise, the center of gravity of the vertical pendulum body 41 will shift, and the vertical pendulum body 41 will shift the vertical pendulum to push or pull the follower push rod 34, so that the locking sleeve 32 locks the cleaning vertical rod 23; the vertical pendulum body 41 will only release the locking sleeve 32 from the cleaning vertical rod 23 when the center of gravity is vertical. That is to say, when the cleaning vertical rod 23 is in a vertical state in the rotating rod 21, the vertical pendulum body 41 is in a vertical state of gravity. The rotating rod 21 rotates and synchronously drives the cleaning vertical rod 23. During the rotation process, the locking sleeve 32 can be controlled by the vertical pendulum body 41 to lock the cleaning vertical rod 23, so that the cleaning vertical rod 23 is locked when it rotates with the rotating rod 21, and will not slide. Then the special-shaped debris barrier 1 is blocked by the cleaning vertical rod 23 The large-area suspended debris intercepted is salvaged from the water. When the end of the cleaning vertical rod 23 rotates to just above the special-shaped debris barrier 1, the cleaning vertical rod 23 is in a vertical state. At the same time, the vertical pendulum body 41 is reset to a vertical state of the center of gravity, and synchronously drives the follower push rod 34 to disengage the locking sleeve 32 from the cleaning vertical rod 23. The cone clamping rod 36 is no longer fixed in the cone clamping groove 37, and the lock on the cleaning vertical rod 23 is released. At this time, the cleaning vertical rod 23 slides downward by its own weight under the action of the gravity of the counterweight body 231; at the same time, when the cleaning vertical rod 23 becomes vertical, the salvaged suspended debris will also fall by its own weight into the concave arc portion 12 at the top of the special-shaped debris barrier 1, and the suspended debris is collected in the concave arc portion 12, thereby realizing the filtration and collection of suspended debris in the waterway 9.

[0043] The swing range of the cleaning vertical rod 23 is 180 degrees. When one end of the cleaning vertical rod 23 rotates to just above the special-shaped debris barrier 1, the vertical pendulum body 41 will reset to a vertical state of the center of gravity, and synchronously drive the follower push rod 34 to disengage the locking sleeve 32 from the cleaning vertical rod 23, and the cone clamping rod 36 is no longer fixed in the cone clamping groove 37, thereby releasing the lock of the cleaning vertical rod 23. At this time, under the gravity of the counterweight body 231, the cleaning vertical rod 23 will slide downward by its own weight and reset to its initial state. The cleaning vertical rod 23 automatically resets itself during the rotation process by relying on the counterweight mechanism to achieve continuous debris filtering and cleaning; at the same time, in the process of the cleaning vertical rod 23 sliding downward by its own weight, it will synchronously press the brushing assembly 6 to move downward to brush and scrape off the fine suspended debris on the auxiliary filter screen 5; the auxiliary filter screen 5 is used to intercept fine suspended debris and provide a secondary filtering function.

[0044] That is, only when the cleaning vertical rod 23 is in a vertical state, the pendulum body 41 will not control the locking sleeve 32 to lock the cleaning vertical rod 23; when the rotating rod 21 rotates, it synchronously drives the cleaning vertical rod 23 to make the cleaning vertical rod 23 in an inclined state, and at the same time, the rotation of the rotating rod 21 will also synchronously drive the pendulum body 41. When the pendulum body 41 rotates with the rotating rod 21, the center of gravity of the pendulum body 41 will shift, and the offset pendulum of the pendulum body 41 will push or pull the follower push rod 34, so that the locking sleeve 32 locks the cleaning vertical rod 23.

[0045] The center of gravity offset of the pendulum body 41 can control the locking and unlocking process of the locking sleeve 32. The locking state of the locking sleeve 32 on the cleaning vertical rod 23 is determined by using the change in the center of gravity position of the pendulum body 41. The pendulum body 41 can unlock the cleaning vertical rod 23 when the center of gravity is vertical, and lock the cleaning vertical rod 23 when it is offset.

[0046] Through the coordinated cooperation of the special-shaped debris screen 1 and the rotating filter screen 2, large-area debris floating in the water can be filtered and collected; the auxiliary filter net 5 can filter the fine debris suspended in the water; the sediment treatment component can clean the sediment on the bottom of the water; through the coordinated action of various components, all-round filtering and cleaning of the water body can be achieved.

[0047] Embodiment 2, a sewage filtering device for a water conservancy project in this embodiment is described centering on the differences from Embodiment 1.

[0048] In this embodiment, a conveying auger is installed in the concave arc portion 12 at the top of the special-shaped debris barrier 1. The conveying auger can convey the suspended debris collected by the rotating filter grating 2 to the concave arc portion 12. The output end of the conveying auger can extend out of the waterway 9, and the debris collection tank is connected to the output end of the conveying auger. The filtered debris can be conveyed and collected by the conveying auger, and there is no need to manually clean the debris in the concave arc portion 12, thereby improving the filtering efficiency of the device. The above description is only a preferred embodiment of the present invention and does not limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
