A lifting device 3 for driving the gate 2 to move up and down is provided between the dam body 1 and the gate 2. The gate 2 is provided with a plurality of debris removal ports 21 spaced apart in the height direction near its top. The gate 2 is provided with a multi-stage opening and closing mechanism 4, which is used to control the opening or closing of a single debris removal port 21. A plurality of debris removal mechanisms 5 are provided on one side of the debris removal port 21, and the plurality of debris removal mechanisms 5 are evenly spaced along the water flow direction, and the debris removal mechanisms 5 are used to intercept and remove impurities floating on the water surface.

[0030] When it is necessary to adjust the water level or control the water flow, the lifting device 3 is started to drive the gate 2 to move up and down to adjust the water output. A plurality of debris removal ports 21 are arranged at intervals along the height direction near the top of the gate 2. The multi-stage opening and closing mechanism 4 is arranged on the gate 2 to control the opening or closing of a single debris removal port 21. When it is necessary to clean the impurities floating on the water surface, the operator controls the multi-stage opening and closing mechanism 4 and selectively opens the corresponding debris removal port 21 according to the water level. Then the debris removal mechanism 5 is started. The debris removal mechanism 5 intercepts and collects the floating objects on the water surface passing through the debris removal port 21, such as garbage, algae, etc., and collects and salvages them. When one group of debris removal mechanisms 5 completes the impurity collection and the filter box 55 moves to one side of the dam body 1 for cleaning, the other group of debris removal mechanisms 5 can be put into operation immediately to ensure the continuity of the debris removal process, avoid interruptions in the debris removal process, reduce waiting time, and improve the efficiency of debris removal.

[0031] In some embodiments, reference Figure 2 and Figure 3 The multi-stage opening and closing mechanism 4 includes a driving screw 41 rotatably connected to the gate 2, and a driving motor 42 is provided at one end of the driving screw 41. The gate 2 is slidably connected with a plurality of opening and closing doors 43 in the height direction, and the plurality of opening and closing doors 43 correspond to the plurality of impurity removal ports 21 one by one. For example, the gate 2 is fixed with a dovetail block 44 in the height direction, and a dovetail groove 431 is provided on the opening and closing door 43, and the dovetail block 44 is inserted into the dovetail groove 431. A plurality of lifting sleeves 45 are threadedly sleeved on the outer side of the driving screw 41, and the plurality of lifting sleeves 45 correspond to the plurality of opening and closing doors 43 one by one, and the lifting sleeves 45 are rotatably connected with the corresponding opening and closing doors 43, and the rotatable connection is used to prevent the lifting sleeves 45 and the corresponding opening and closing doors 43 from being easily dislocated up and down due to factors such as vibration. A connecting assembly 46 is provided between the lifting sleeve 45 and the corresponding opening and closing door 43, and the connecting assembly 46 is used to control the lifting sleeve 45 to connect with the corresponding opening and closing door 43. A limit assembly 47 is provided between the opening and closing door 43 and the gate 2 , and the limit assembly 47 is used to control the up and down movement range of the opening and closing door 43 so as to quickly locate the opening or closing state of the opening and closing door 43 .

[0032] When it is necessary to control the opening or closing of the debris removal port 21, first, according to the water level, the lifting sleeve 45 is selectively connected to the opening and closing door 43 to be opened through the connecting component 46, and then the driving motor 42 is started. The driving motor 42 drives the driving screw 41 to rotate, and the driving screw 41 drives the lifting sleeve 45 to rotate. The lifting sleeve 45 drives the opening and closing door 43 to slide in the height direction through the connecting component 46, thereby controlling the opening or closing of the debris removal port 21. In the process of opening or closing the opening and closing door 43, the limit component 47 can limit the up and down movement range of the opening and closing door 43 to ensure that the opening and closing door 43 can be quickly positioned to the open or closed state to avoid excessive movement or inaccurate position, thereby accurately opening or closing the debris removal port 21 to intercept and remove floating impurities on the water surface.

[0033] In some embodiments, reference Figure 4 and Figure 5 The connection assembly 46 includes a support sleeve 461 fixed to the outside of the lifting sleeve 45. Two connection blocks 462 are slidably connected inside the support sleeve 461. The two connection blocks 462 are symmetrically arranged. A connection groove 432 is provided in the opening and closing door 43. The connection block 462 can extend out of the support sleeve 461 and be plugged into the connection groove 432. A guide angle is provided on the side of the connection block 462 close to the connection groove 432. The guide angle is used to guide the connection block 462 to be inserted into the connection groove 432 more smoothly, reduce the resistance during the insertion process, and make the connection assembly 46 less likely to get stuck during operation. A synchronous telescopic component 463 is provided between the two connection blocks 462. The synchronous telescopic component 463 is used to control and drive the two connection blocks 462 to synchronously extend or retract into the support sleeve 461.

[0034] When the lifting sleeve 45 is connected to the corresponding opening and closing door 43 through the connecting component 46, the lifting sleeve 45 and the supporting sleeve 461 are first driven to rotate by the driving screw 41, and the supporting sleeve 461 drives the connecting block 462 to align with the connecting groove 432, and then the synchronous telescopic component 463 drives the connecting block 462 to move to the side close to the connecting groove 432, so that the connecting block 462 is inserted into the inside of the connecting groove 432, and the lifting sleeve 45 and the corresponding opening and closing door 43 can be connected; wherein, through the two symmetrical connecting blocks 462, the opening and closing door 43 can be subjected to uniform force and maintained in balance during the movement, avoiding the deviation or shaking caused by a single connection point, and the synchronous telescopic component 463 makes the two connecting blocks 462 move in unison when extending and retracting the supporting sleeve 461, thereby improving the accuracy and stability of the connection.

[0035] In some embodiments, reference Figure 4 and Figure 5, the synchronous telescopic component 463 includes a rotating shaft 4631 rotatably connected to the lifting sleeve 45, and a power motor 4632 is arranged at one end of the rotating shaft 4631. A driving block 4633 is fixedly arranged on the rotating shaft 4631, and the middle part of the driving block 4633 is fixedly connected to the rotating shaft 4631. Exemplarily, the driving block 4633 is disc-shaped, and two driven rods 4634 are hinged at the edge of the driving block 4633. The two driven rods 4634 correspond to the two connecting blocks 462 one by one, and the end of the driven rod 4634 away from the driving block 4633 is hinged to the corresponding connecting block 462. A torsion spring 4635 is also arranged between the driving block 4633 and the lifting sleeve 45. The torsion spring 4635 is always in a pre-tightened state and gives a certain torsional force to the rotating shaft 4631 and the driving block 4633, so that the driven rod 4634 drives the connecting block 462 to a force toward the connecting groove 432.

[0036] When the two connecting blocks 462 are driven to synchronously extend or retract into the supporting sleeve 461 through the synchronous telescopic component 463, the power motor 4632 is started first, and then the power motor 4632 drives the rotating shaft 4631 to rotate. The rotation of the rotating shaft 4631 causes the driving block 4633 fixedly connected thereto to rotate accordingly, and the driving block 4633 synchronously drives the two driven rods 4634 to move, and the driven rod 4634 drives the connecting block 462 to extend or retract the supporting sleeve 461, thereby realizing the connection or disconnection with the connecting groove 432 of the opening and closing door 43. When there is no need to clean impurities such as garbage and algae on the water surface through the debris removal port 21, the opening and closing door 43 needs to be in a closed state. At this time, the torsion spring 4635 is always in a pre-tightened state, giving a certain torsional force to the rotating shaft 4631 and the driving block 4633, and the driven rod 4634 drives the connecting block 462 to be inserted into the connecting groove 432, so that the opening and closing door 43 can be firmly closed, and the opening and closing door 43 is not easily accidentally opened by the impact or vibration of water.

[0037] In some embodiments, reference Figure 3 The limit assembly 47 includes an upper limit rod 471 and a lower limit rod 472 respectively fixed on the upper and lower sides of the debris removal opening 21 of the opening and closing door 43. When the opening and closing door 43 is in the process of lifting, the upper limit rod 471 and the lower limit rod 472 play a limiting role, limiting the maximum stroke of the opening and closing door 43 moving up and down, ensuring that the opening and closing door 43 stops accurately at the predetermined position to avoid excessive lifting.

[0038] In some embodiments, reference Figure 6The impurity removal mechanism 5 includes a horizontal movable seat 51 slidably connected to the dam body 1. Exemplarily, a guide rail 52 is fixedly provided on the dam body 1, and the horizontal movable seat 51 is slidably connected to the guide rail 52. A linear motor 53 is provided between the horizontal movable seat 51 and the dam body 1, and the output end of the linear motor 53 is connected to the horizontal movable seat 51. A winch 54 is provided on the horizontal movable seat 51, and the free end of the rope of the winch 54 is connected to a filter box 55. A support frame 56 is fixedly provided on one side of the filter box 55, and a support groove 11 is opened in the height direction of the dam body 1. The support frame 56 is inserted into the support groove 11. The support frame 56 and the support groove 11 are used to provide stable support for the filter box 55, so that the filter box 55 is not easy to shake and shift under the impact of water flow, thereby improving the stability of the filtering operation.

[0039] When the impurity removal port 21 is opened, the filter box 55 can be lowered underwater under the drive of the winch 54 to collect floating impurities on the water surface. When the collected floating impurities need to be cleaned, the filter box 55 is first raised above the water surface under the drive of the winch 54, and then the linear motor 53 is started, and the linear motor 53 drives the horizontal moving seat 51 and the filter box 55 to move horizontally along the dam body 1, so that the filter box 55 moves to one side of the dam body 1, and then the staff can clean the impurities in the filter box 55.

[0040] The implementation principle of an adjustable sluice device for a water conservancy project in the embodiment of the present application is as follows: the gate 2 is connected to the gate chamber by sliding, and can move up and down in the height direction. When it is necessary to adjust the water level or control the water flow, the lifting device 3 is started to drive the gate 2 to move up and down to adjust the water output; a plurality of debris removal ports 21 are provided at intervals in the height direction near the top of the gate 2, and a multi-stage opening and closing mechanism 4 is provided on the gate 2 to control the opening or closing of a single debris removal port 21. When it is necessary to clean up the impurities floating on the water surface, the operator controls the multi-stage opening and closing mechanism 4 to selectively open the corresponding debris removal port 21 according to the water level, and then removes the impurities. The mechanism 5 is started, and the debris removal mechanism 5 intercepts and collects the floating objects on the water surface, such as garbage, algae, etc., passing through the debris removal port 21, and salvages and collects them; wherein, through the coordinated use of the multi-stage opening and closing mechanism 4, the debris removal mechanism 5 and the plurality of debris removal ports 21, the sluice device can not only effectively control the water flow and adjust the water level, but also select to open the appropriate debris removal port 21 according to the height of the upstream water level, and drain the upper water surface close to the gate 2 side and intercept and filter the floating objects on the water surface, such as garbage and algae, to prevent the floating garbage and algae from long-term accumulation and fermentation to produce a large amount of unpleasant odor, so as to clean the water surface and improve the cleanliness of the water body.
