Description

Technical Field

[0001] This utility model relates to the field of waterway engineering technology, and in particular to a gate-type drainage outlet for waterway dredging and reclamation areas. Background Technology

[0002] Channel dredging and reclamation areas refer to engineering areas where dredged sediment from waterways is pumped into designated areas to form land or reinforce dikes. This technology is widely used in land reclamation, port expansion, and waterway maintenance, aiming to solve the problem of scarce land resources, improve sediment utilization, and reduce environmental pollution.

[0003] The development of reclamation projects has continuously placed higher demands on reclamation technology and equipment. The issue of drainage outlet setting has always been one of the main problems related to the smooth progress of reclamation projects. Traditional reclamation areas do not have filter screens. After long-term use, the overflowing water often carries a certain amount of silt, which is not conducive to the later drainage of the collection tank and easily causes the drainage pipe to be blocked. The patent (CN 212405047 U) proposes to horizontally and fixedly install three layers of filter screens with different pore sizes in the reclamation area. However, when the amount of silt increases sharply, the fixed filter screens are prone to blockage due to the rapid accumulation of silt. Frequent shutdowns for cleaning are required, which affects drainage efficiency. At the same time, manual cleaning is required, which is labor-intensive and has high labor costs.

[0004] Therefore, this application provides a gate-type drainage outlet for dredging and reclamation areas of waterways to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this utility model is to provide a gate-type drainage outlet for dredging and reclamation areas of waterways, which solves the problems of existing devices where the horizontal fixed installation of the filter screen easily causes mud to accumulate on the filter screen and makes it inconvenient to clean the filter screen.

[0007] A further improvement of the present invention is that the filter assembly also includes two fixed columns vertically set on the top surface of the channel embankment, a movable column is movably fitted inside the fixed column, a rectangular bracket is fixedly set at the top of the movable column, and two sets of parallel slide blocks are set vertically at a distance on the outer sides of the two vertical legs of the bracket, with a sliding groove opened on the opposite side of each set of slide blocks.

[0008] A further improvement of this utility model is that a lead screw passes through the middle of the bracket, the lead screw is threadedly engaged with the bracket, and the top of the lead screw is electrically connected to a motor A fixed at the top of the fixed frame through the fixed frame. The bracket moves up and down along the axis of the lead screw by rotating the motor A.

[0009] A further improvement of the present invention is that the fixing frame is an n-shaped structure, the lower end of the fixing frame is vertically fixed to the gate fixing dam body, the fixing block is integrally set on the side of the fixing frame body, the rope roller is movably passed between the two fixing blocks, one end of the rope roller is connected to motor B, and motor B is fixed to the outer wall of the fixing block.

[0010] A further improvement of the present invention is that the first filter screen and the second filter screen have the same structure and size. The first filter screen also includes a rectangular filter screen frame with an edge. Sliding strips are integrally provided at the ends of the two long sides of the filter screen frame. The two outer sliding strips are adapted to be embedded in two horizontally opposite sliding grooves.

[0011] A further improvement of this utility model is that: the filter frame body is provided with mesh surfaces of different apertures in the middle, and the mesh aperture of the first filter is smaller than that of the second filter.

[0012] A further improvement of this utility model is that the width of the filter screen frame is equal to the length of the slide block.

[0013] A further improvement to the technical solution of this utility model is that a barrier net is installed at the top of the gate body.

[0014] A further improvement of this utility model is that the top of the fixing frame is 20-50cm higher than the top of the gate.

[0015] A further improvement to the technical solution of this utility model is that a sedimentation tank is provided at the bottom of the side of the reclamation area near the gate, and a drainage outlet is provided at the bottom of the water collection tank.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects:

[0017] 1. This utility model provides a gate-type drainage outlet for a dredging and reclamation area of ​​a waterway. The first and second filter screens are embedded in the sliding grooves at their outer ends, and the inner ends of the first and second filter screens are movably placed on the top surface of the sliding block body. The inner sides of the first and second filter screens can be pulled upward by ropes, while the outer ends slide inward in the sliding grooves, causing the outer sides of the first and second filter screens to tilt downward, which facilitates the natural sliding of sand and gravel on the first and second filter screen bodies into the sedimentation tank, reducing the large accumulation of sediment on the first and second filter screens, and facilitating sediment cleaning.

[0018] 2. The present invention provides a gate box-type drainage outlet for a dredging and reclamation area of ​​a waterway. The bracket is fixed to the top of a movable column. The movable column can extend and retract within the fixed column under the drive of motor A and lead screw. This allows for appropriate adjustment of the height of the first and second filter screens according to the accumulation thickness of silt in the reclamation area, preventing the first and second filter screens from being buried by silt. It also allows the first and second filter screens to adapt to the silt height in the reclamation area, enabling the silt in the reclamation area to accumulate continuously and improving the reclamation efficiency.

[0019] 3. The present invention provides a gate-type drainage outlet for a dredging and reclamation area of ​​a waterway. The aperture of the first and second filter screens increases from top to bottom, which can effectively filter mud, sand and gravel of different sizes in the water. The filtered water overflows into the collection tank through the barrier net. The barrier net can intercept some floating objects such as branches. The water in the collection tank is finally discharged through the drainage outlet. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] The present invention will be further explained below with reference to specific embodiments.

[0033] like Figures 1-7 As shown, this embodiment provides a gate-type drainage outlet for a dredging and reclamation area, including a channel dam 1, a reclamation area 2 set on one side of the channel dam 1, a water collection trough 3 set on one side of the reclamation area 2, a gate-fixed dam 4 set between the water collection trough 3 and the reclamation area 2, and a gate 5 vertically set in the middle of the gate-fixed dam 4 body; a filter assembly 6 is set on the side of the gate 5 near the reclamation area 2, and the filter assembly 6 also includes two sets of slide blocks 61, on which a first filter screen 62 and a second filter screen 63 are respectively adapted and movably installed; a rope 70 is vertically set on the rear end face of the first filter screen 62 and the second filter screen 63 body, and the rope 70 is vertically wound upward on the rope roller 71; the rope roller 71 rotates to wind up the rope 70, causing the first filter screen 62 and the second filter screen 63 to tilt, so that the mud and sand on the upper surface of the first filter screen 62 and the second filter screen 63 body can freely slide down and settle; Specifically, a sedimentation tank 21 is installed at the bottom of the side of the reclamation area 2 near the gate 5. The sedimentation tank 21 facilitates sediment sedimentation. Water in the reclamation area 2 overflows into the collection tank 3 through the baffle 51 at the top of the gate 5. During the overflow, the water containing sediment passes through the first filter screen 62 with a larger aperture and the second filter screen 63 with a smaller aperture located above the first filter screen 62. This effectively filters out sediment of different particle sizes. The filtered water then enters the collection tank 3 and is discharged from the drain outlet 31 at the bottom of the collection tank 3. After a period of time, the rope roller 71 can be rotated by the motor B72, thereby causing the outer sides of the first filter screen 62 and the second filter screen 63 to tilt downwards, so that the sediment accumulated on the first filter screen 62 and the second filter screen 63 naturally slides down into the sedimentation tank 21, completing the quick cleaning of the first filter screen 62 and the second filter screen 63.

[0034] like Figures 2-5As shown, in this embodiment, the filter assembly 6 further includes two fixed columns 64, with a movable column 65 movably fitted inside each fixed column 64. A rectangular bracket 66 is fixedly mounted on the top of the movable column 65. Two sets of parallel slide blocks 61 are vertically spaced on the outer sides of the two vertical legs 661 of the bracket 66, with grooves 611 formed on opposite sides of each set of slide blocks 61. A lead screw 67 passes through the middle of the bracket 66, threadedly engaging with the bracket 66. The top of the lead screw 67 movably passes through a fixed frame 68 and is electrically connected to a motor A69 fixed to the top of the fixed frame 68. The rotation of the motor A69 causes the support to... The support 66 moves up and down along the axis of the lead screw 67; the fixed frame 68 has an n-shaped structure, with its lower end vertically fixed to the main body of the gate fixing dam 4. A fixing block 681 is integrally set on the side of the fixed frame 68, and a rope roller 71 movably passes between the two fixing blocks 681. One end of the rope roller 71 is connected to a motor B72, which is fixed to the outer wall of the fixing block 681. Specifically, the ball block slider and lead screw 67 are commercially available products, and their specific structures and principles are not detailed here. Furthermore, the lead screw 67 and motor A69 can be installed and used only when it is necessary to lift the support 66 upwards. The lower end of column 64 extends vertically and is fixed to the body of the channel embankment 1. Column 64 supports fixed bracket 66. Slide blocks 61 are provided on the outer side of the legs 661 of bracket 66. Slide blocks 61 support and install the first filter screen 62 and the second filter screen 63. Two sliding strips 623 on the outer sides of the first filter screen 62 and the second filter screen 63 are embedded in sliding grooves 611. Ropes 70 are fixedly connected to the inner side of the filter frame 621 of the first filter screen 62 and the second filter screen 63. Ropes 70 can pull the inner sides of the first filter screen 62 and the second filter screen 63 upwards, simultaneously causing the sliding strips 623 to slide upwards. The first filter screen 62 and the second filter screen 63 slide inwards within the groove 611, causing the first filter screen 62 and the second filter screen 63 to tilt inwards, with the inner side higher than the outer side. The silt on the top surface of the first filter screen 62 and the second filter screen 63 slides down into the silt sedimentation tank 21 under the action of gravity. At the same time, as the silt in the silt sedimentation tank 21 accumulates higher and higher, the motor A69 can drive the rectangular bracket 66 fixed at the top of the movable column 65 to move upwards through the ball slider (not shown in the figure) in conjunction with the lead screw 67. This will drive the first filter screen 62 and the second filter screen 63 to move upwards, thus preventing the first filter screen 62 and the second filter screen 63 from being buried by silt and affecting the filtration effect.

[0035] like Figure 4 , Figure 6 , Figure 7As shown, in this embodiment, the first filter screen 62 and the second filter screen 63 have the same structure and size. The first filter screen 62 also includes a rectangular filter screen frame 621 with an edge. Sliding strips 623 are integrally provided at the ends of the two opposite long sides of the filter screen frame 621. The two outer sliding strips 623 are adapted to be embedded in the two horizontally opposite sliding grooves 611. The filter screen frame 621 body is provided with a mesh surface 622 with different apertures in the middle. The aperture of the mesh surface 622 of the first filter screen 62 is smaller than that of the mesh surface 622 of the second filter screen 63. Specifically, the filter screen frame 621 has a rectangular structure. The long side of the filter screen frame 621 protrudes vertically from the short side to form a sliding strip 623. The two outer sliding strips 623 are used to insert into the sliding grooves 611, and the two inner sliding strips 623 are placed on the body of the slide block 61. During the overflow process, water containing silt will pass through the first filter screen 62 with a larger aperture and the second filter screen 63 with a smaller aperture located above the first filter screen 62 in sequence, which can effectively filter out silt of different particle sizes.

[0036] like Figures 1-2 As shown, in this embodiment, a sedimentation tank 21 is provided at the bottom of the reclamation area 2 near the gate 5, and a drain outlet 31 is provided on the bottom surface of the water collection tank 3; the width of the filter screen frame 621 is equal to the length of the slide block 61; a baffle 51 is provided at the top of the gate 5 body; the top of the fixing frame 68 is 20-50cm higher than the top of the gate 5; specifically, the filtered water overflows into the water collection tank 3 through the baffle 51, which can intercept some floating objects such as branches, and the water in the water collection tank 3 is finally discharged through the drain outlet 31, and the fixing frame 68... The frame has an n-shaped structure. The top of the fixing frame 68 is 50cm higher than the top of the gate 5. This height is greater than the water overflow height. The bottom of the fixing frame 68 is vertically fixed inside the gate fixing dam 4. The two ends of the rope roller 71 pass through the fixing block 681 integrally set on the front side of the fixing frame 68 and are connected to the motor B72. The motor B72 is used to drive the rope roller 71 to rotate, thereby lifting the inner side of the first filter screen 62 and the second filter screen 63 upward through the rope 70, thus completing the angular tilting of the first filter screen 62 and the second filter screen 63.

[0037] This utility model provides a working principle for a gate-type drainage outlet in a dredging and reclamation area: At high tide, water containing silt flows into the reclamation area 2. During its flow, the silt-laden water first enters the sedimentation tank 21, where some silt settles under gravity. The remaining silt-laden water passes through the first filter screen 62 and the second filter screen 63, overflowing from the baffle 51 at the top of the gate 5 into the collection tank 3. After a period of time, the motor B72 rotates the rope roller 71, causing the outer sides of the first and second filter screens 62 and 63 to tilt downwards, allowing the water accumulated in the sediment to settle. The silt on the first filter screen 62 and the second filter screen 63 naturally slides into the silt settling tank 21, completing the quick cleaning of the first filter screen 62 and the second filter screen 63; at the same time, as the silt in the silt settling tank 21 accumulates higher and higher, when it is necessary to lift the movable column 65, work is stopped for 1-2 days to allow the silt to settle freely before lifting. The motor A69 can drive the rectangular bracket 66 fixed at the top of the movable column 65 to move upward by rotating the lead screw 67, thereby driving the first filter screen 62 and the second filter screen 63 to move upward, avoiding the first filter screen 62 and the second filter screen 63 being buried by silt and affecting the filtration effect.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
