Description

Technical Field

[0001] The invention relates to the technical field of water conservancy gates, and in particular to a water conservancy gate flow control device. Background Art

[0002] In order to reasonably control and allocate various water resources in nature, various dams, sluices and channels are often built. Such projects are collectively referred to as water conservancy projects. Among them, water conservancy gates can be used to control water flow, divert floods or create waterfall landscape lights, etc. Water conservancy gate control is an important technical part of controlling water resource scheduling. However, existing water conservancy gates generally adopt an overall lifting opening method. Regardless of the size of the gate opening, when the gate is opened, the bottom of the river always flows first, resulting in a large amount of silt at the bottom of the river mixed in the flowing water. In addition, floating debris on the river surface will also flow to the downstream river with the opening of the gate, and it will not be able to intercept the debris, thereby affecting the water quality of the downstream river. Summary of the invention

[0003] In view of the above shortcomings, the present invention proposes a hydraulic gate flow control device, which can not only collect floating debris in the river through an interception frame, but also use an interception plate to prevent riverbed silt from flowing to the downstream river, thereby reducing the impact of upstream debris and sludge on the downstream.

[0006] According to the hydraulic gate flow control device of the embodiment of the present invention, at least the following beneficial effects are achieved: when the water level is controlled on a daily basis, the second driving mechanism drives the interception frame to move upward, so that the second opening gradually overlaps with the first opening, thereby controlling the overlap between the first opening and the second opening, on the one hand, it is possible to discharge water from the upper part of the river, and on the other hand, it is possible to allow floating debris in the river to flow into the interception frame through the second opening, thereby using the interception frame to collect and temporarily store floating debris in the river. When it is necessary to increase the amount of water discharged from the river, the first driving mechanism drives the gate to move upward, and the linkage mechanism drives the interception plate to move downward, so that the interception plate is inserted into the riverbed to form a barrier to the flow of sludge at the riverbed. Through the above structure, not only can the flow of the river be controlled according to different usage requirements, but also floating debris and sludge at the riverbed can be intercepted in the corresponding usage scenarios, thereby reducing the impact of upstream debris and sludge on the downstream.

[0025] See also Figures 1 to 3 A flow control device for a water conservancy gate 110 comprises: a frame 100, on which a gate 110 is movably arranged, the gate 110 is provided with a first opening 111, and the gate 110 is provided with a first driving mechanism for driving it to move in a vertical direction; an interception frame 200, which is movably arranged on the frame 100, the side wall of the interception frame 200 is in contact with the inner wall of the gate 110, the interception frame 200 is connected with a second driving mechanism for driving it to move in a vertical direction, the interception frame 200 is provided with a cavity for temporarily storing debris, the interception frame 200 is provided with a second opening 201 communicated with the cavity, and the interception frame 200 can block or open the first opening 111 during movement; an interception plate 300, which is movably arranged on the frame 100, a linkage mechanism is provided between the interception plate 300 and the gate 110, and the linkage mechanism is used to drive the interception plate 300 and the gate 110 to move in opposite directions.

[0026] The flow control device of the hydraulic gate 110 of the above structure, when the flow control of the water level is performed on a daily basis, the second driving mechanism drives the interception frame 200 to move upward, so that the second opening 201 gradually overlaps with the first opening 111, thereby controlling the overlap between the first opening 111 and the second opening 201, on the one hand, it is possible to discharge water from the upper part of the river, and on the other hand, it is possible to allow floating debris in the river to flow into the interception frame 200 through the second opening 201, so that the interception frame 200 is used to collect and temporarily store floating debris in the river. When it is necessary to increase the amount of water discharged from the river, the first driving mechanism drives the gate 110 to move upward, and the linkage mechanism drives the interception plate 300 to move downward, so that the interception plate 300 is inserted into the river bottom to form a barrier to the flow of sludge at the river bottom. Through the above structure, not only can the flow of the river be controlled according to different usage requirements, but also the floating debris and sludge at the river bottom can be intercepted in the corresponding usage scenarios, thereby reducing the impact of upstream debris and sludge on the downstream.

[0027] See also Figures 1 to 3 , further, the first driving mechanism includes a screw rod 112 rotatably arranged on the frame 100, the gate 110 is connected to a first slider 113 threadedly matched with the screw rod 112, one end of the screw rod 112 is connected to a first motor 114 driving it to rotate, the frame 100 is provided with a guide rod 115 arranged parallel to the screw rod 112, and the gate 110 is connected to a second slider 116 mutually matched with the guide rod 115. Specifically, the first motor 114 drives the screw rod 112 to rotate, so that the first slider 113 moves in the vertical direction under the action of the thread, and under the guiding action of the second slider 116 and the guide rod 115, the gate 110 can achieve translational movement in the vertical direction, so that the water release effect of a large flow of the river can be achieved by controlling the lifting and lowering of the gate 110. Among them, the output end of the first motor 114 is connected to a bevel gear 310 reducer, so as to change the transmission direction of the force output by the first motor 114, which is conducive to adjusting the installation position of the first motor 114.

[0028] See also Figures 1 to 3, further, the interception frame 200 includes a bottom plate 202, the bottom plate 202 is provided with a plurality of filter holes 203, the bottom plate 202 is connected to four frame plates 204, the second opening 201 is provided in one of the frame plates 204, and the four frame plates 204 together enclose a cavity. Specifically, when the second driving mechanism drives the interception frame 200 to move upward, the second opening 201 gradually overlaps with the first opening 111, so that the water in the upper part of the river can fall into the cavity through the second opening 201, and the floating debris on the river surface can be intercepted by the filter holes 203, so that the debris can be collected in the interception frame 200 for subsequent processing. It can be understood that the first opening 111 is provided in the middle and upper part of the gate 110, and one of the frame plates 204 abuts against the gate 110. Among them, when the second opening 201 does not overlap with the first opening 111, the frame plate 204 can block the first opening 111 to cut off the upper water discharge of the river. When the second opening 201 gradually overlaps with the first opening 111, water in the upper part of the river can flow to the downstream river through the second opening 201. In addition, the two side plates 101 are provided with slots in the vertical direction, and the gate 110 is clamped between the two slots, thereby improving the effect of the gate 110 in blocking the river drainage.

[0029] See also Figures 1 to 3 Further, the frame 100 includes two side panels 101 arranged opposite to each other, the gate 110 and the interception frame 200 are both arranged between the two side panels 101, the upper ends of the two side panels 101 are connected with a mounting plate 102, and the second driving mechanism is arranged on the mounting plate 102, thereby providing a mounting position for the second driving mechanism. The side panel 101 and the mounting plate 102 can be connected by bolts, which is convenient for the installation of the side panel 101 and the mounting plate 102 or subsequent disassembly for maintenance.

[0030] See also Figures 1 to 3, further, the mounting plate 102 is provided with a third opening 103, the mounting plate 102 is relatively provided with two vertical plates 104, the second driving mechanism includes a second motor 210 provided on the mounting plate 102, the output end of the second motor 210 is connected with a rotating roller 211, the rotating roller 211 is provided between the two vertical plates 104, and the rotating roller 211 is provided with a lifting rope 212 having one end connected to the bottom plate 202. Specifically, when in use, the second motor 210 drives the rotating roller 211 to rotate, so that the rotating roller 211 reels or unwinds the lifting rope 212, so that the interception frame 200 can move in the vertical direction, thereby adjusting the position of the interception frame 200 to change the opening and closing degree of the first opening 111 outputting water. Among them, the setting of the third opening 103 is not only convenient for the use of the lifting rope 212, but also conducive to the subsequent lifting of the interception frame 200 to a certain height, so that people can clean up the debris in the interception frame 200 through the third opening 103. In addition, the output end of the second motor 210 is connected to a bevel gear 310 reducer, thereby changing the transmission direction of the force output by the second motor 210 , which is beneficial to adjusting the installation position of the second motor 210 .

[0031] See also Figures 1 to 3 Furthermore, two vertical poles 105 are parallelly provided on the mounting plate 102, and the interception frame 200 and the interception plate 300 are both provided in through holes that slide with the vertical poles 105, thereby avoiding the interception frame 200 and the interception plate 300 from offsetting during the movement, which is conducive to realizing the translational movement of the interception frame 200 and the interception plate 300.

[0032] See also Figures 1 to 3 , further, the linkage mechanism includes a gear 310 rotatably arranged on one of the side plates 101, and racks 320 are respectively arranged on both sides of the gear 310 for meshing transmission, one of the racks 320 is arranged on the gate 110, and the other rack 320 is arranged on the interception plate 300. Specifically, when in use, the first driving mechanism drives the gate 110 to move upward, so that one of the racks 320 moves upward to drive the gear 310 to rotate, so that the other rack 320 moves downward to drive the interception plate 300 to be inserted downward to the bottom of the river, so that in the process of the gate 110 moving upward to release water, the interception plate 300 can prevent the sludge on the river bottom from flowing with the water, which is conducive to reducing the impact of the upstream sludge on the downstream river.

[0033] Furthermore, the interception frame 200 and the side plate 101 have a spacing space, and the gear 310 and the rack 320 are built into the spacing space, so as to facilitate the installation position of the linkage mechanism.

Specifically, when the second opening 201 coincides with the first opening 111, the water flow impacts the sealing plate 221, thereby driving the sealing plate 221 to rotate, so that the water in the upper part of the river flows into the interception frame 200. When the position of the sealing plate 221 is higher than the water surface of the river, the torsion spring drives the sealing plate 221 to reset to abut against the corresponding frame plate 204, which is conducive to using the sealing plate 221 to prevent the debris in the interception frame 200 from being discharged from the second opening 201, so as to facilitate the subsequent cleaning of the debris.
