Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, and more specifically, to a water conservancy engineering gate with a water purification mechanism. Background Technology

[0002] Hydraulic engineering gates with water purification mechanisms integrate filtration, interception, or active cleaning devices to purify water while controlling water flow. Typical examples include anti-impact, impurity-filtering, and integrated gate-machinery designs. Their core function is to simultaneously regulate river flow and remove impurities, thereby achieving the effect of purifying water quality.

[0003] Gate components such as the gate frame, gate plate, and sealing rings use rubber waterstops, combined with adjustable wedge-shaped pressure blocks, to ensure that the sealing performance is maintained even after prolonged use and wear. When cutting off water flow, the gate closes to intercept the river; when opening, it regulates the water level or discharges floodwater. Gates with filtration and interception structures generally include filter plates and sluice gate structures. The filter plates serve as the first line of defense, while the horizontally arranged sluice gates block impurities in the water flow. The sealing gasket at the bottom of the gate plate fits tightly with the filter plate, forming a double sealing line to prevent impurities from leaking out. Multi-stage filtration media are also set up, using activated carbon, quartz sand, KDF filter media, etc., for layered filtration to adsorb residual chlorine, heavy metals, and organic matter in the water. Gates with active cleaning mechanisms generally include a linkage cleaning mechanism. When the gate is opened, the guide rod drives the linkage frame to extend, causing the filter cover to actively squeeze out the dirt, achieving rapid discharge of dirt. Impurities in the water can also be cleaned by rake plates. By rotating the adjusting threaded rod, the rake plates can be driven to shuttle between the sluice gates, scraping off impurities and collecting them into the collection frame.

[0004] Currently, existing water conservancy gates generally consist of a gate frame and a gate plate. The gate plate is opened and closed to discharge floodwater or intercept rivers. They are also equipped with filtration and interception structures to intercept and collect floating debris and other impurities in the water. However, in rivers with high sediment content, the river water contains a large amount of silt. The silt not only affects the clarity of the river water, but the sediment also raises the riverbed height, affecting the smooth flow of the river. The filtration and interception structures are difficult to filter fine silt, resulting in poor water purification effect. Therefore, they do not meet the existing needs. To address this, we propose a water conservancy gate with a water purification mechanism. Summary of the Invention

[0005] This invention provides a hydraulic engineering gate with a water purification mechanism. This hydraulic engineering gate with a water purification mechanism can intercept and filter silt in river water, improve the clarity of river water, and thus improve the water purification effect. It solves the problem mentioned in the background art that the existing hydraulic engineering gate's filtering and interception structure is difficult to filter fine silt, resulting in poor water purification effect.

This not only enhances the impurity removal effect, but also creates turbulence at the bottom of the water through the rotation of the turbine and the swing of the water discharge, which quickly and effectively introduces the bottom river water carrying a large amount of riverbed sediment into the sandbag for filtration and collection. Therefore, through the mutual cooperation of removing floating impurities and filtering and collecting sediment, water quality is purified in multiple ways, thereby improving the water purification effect.

[0031] According to some embodiments of this disclosure, a hydraulic engineering gate with a water purification mechanism is provided, referenced. Figure 1 — Figure 9 As shown, the water conservancy gate with a water purification mechanism includes a gate frame 100, a base plate 110, and a rotatably mounted gate plate 120. Two gate frames 100 are provided, one on each side of the river channel.

A telescopic member 123 is hinged to the outside of the fixed plate 122. The telescopic member 123 is set as a hydraulic rod, or can be designed according to the actual situation. The telescopic end of the telescopic member 123 is hinged to the rear side of the gate plate 120. The lower end of the gate plate 120 is rotatably engaged with the side of the base plate 110. A sealing sheet 124 is fixedly connected between the lower end of the gate plate 120 and the base plate 110. The sealing sheet 124 is set as an elastic rubber sheet, thereby sealing the gap at the rotatable connection between the gate plate 120 and the base plate 110.

[0032] A debris removal assembly 130 is provided on the front side of the gate 120. The debris removal assembly 130 is used to remove floating objects on the water surface. The debris removal assembly 130 includes conveyor rollers 131 rotatably installed between the gate frames 100, a conveyor belt 132 sleeved between the conveyor rollers 131, an interceptor plate 133 fixedly installed on the outside of the conveyor belt 132, a first motor 134 installed on the side of the gate frame 100 for driving the conveyor rollers 131, and a collection frame 135 set between the gate frames 100 for collecting debris. The interceptor plate 133 is set as an arc plate, which can more effectively intercept and retrieve debris floating under the conveyor belt 132. The collection frame 135 can be set as a mesh frame to facilitate the drainage of water from the collection frame 135. Two conveyor rollers 131 are provided. One conveyor roller 131 is rotatably mounted on the upper side of the door frame 100 via a bearing, and the other conveyor roller 131 is rotatably mounted below the water surface via a bearing. A conveyor belt 132 is sleeved between the two conveyor rollers 131, and the conveyor belt 132 is provided with uniform mesh holes, so that the conveyor belt 132 can filter and intercept floating objects on the water surface without obstructing the water flow. Several interception plates 133 are provided, and the interception plates 133 are evenly distributed on the conveyor belt 132. The first motor 134 is fixedly mounted on the side of the door frame 100, and the output shaft of the first motor 134 is interference-fitted into the side of the conveyor roller 131 located on the upper side of the door frame 100.

[0033] A housing 140 is slidably disposed between door frames 100. A drive assembly 150 for driving the housing 140 to rise and fall is disposed inside the door frame 100. The drive assembly 150 includes a slider 151 fixedly installed on the side of the housing 140 and slidably inserted into the side wall of the door frame 100, a lead screw 152 rotatably disposed inside the door frame 100 and threadedly connected to the slider 151, and a second motor 153 fixedly installed on the outside of the door frame 100 and connected to the lead screw 152. The number of sliders 151 is set to two, and the two sliders 151 are respectively fixedly installed on both sides of the housing 140 and slidably inserted into the side walls of the two door frames 100. The second motor 153 is fixedly installed on the top of one of the door frames 100, and the output shaft of the second motor 153 is fixedly connected to the top of the lead screw 152.

[0034] A water pipe 160 is connected to the outside of the housing 140. The water pipe 160 is connected to an external water source via a water pump (not shown in the figure) or to river water via a water pump, which facilitates pumping water into the water pipe 160. The water pipe 160 is designed as a flexible hose to avoid obstructing the raising and lowering of the housing 140. A water drain 170 is fixedly installed on the outside of the housing 140. A nozzle 180 is provided on the side of the water drain 170. A cavity is opened on the inside of the housing 140. The water pipe 160 is connected to the cavity opened on the inside of the housing 140. The cavity is connected to the water drain 170. There are two water drains 170. Each water drain 170 is provided with several nozzles 180 on its side. The water outlet angle of the nozzles 180 is different to expand the spray range of the nozzles 180, so that the water flow sprayed by the nozzles 180 can more comprehensively lift the silt deposited at the bottom of the river.

[0035] A sand-flowing outlet 190 is provided on the lower side of the gate 120. A baffle 200 is slidably disposed on the side of the sand-flowing outlet 190. In the initial state, the baffle 200 closes the sand-flowing outlet 190, and the seal between the baffle 200 and the sand-flowing outlet 190 is achieved by conventional technical means, which is well known to those skilled in the art and will not be described in detail here. The baffle 200 is slidably inserted into the inner side of the gate 120, and a limiting piece 201 is fixedly installed on the outer side of the baffle 200. The limiting piece 201 is slidably disposed. Inside the gate 120, there are two limiting pieces 201. The two limiting pieces 201 are fixedly installed on both sides of the baffle 200. A spring 202 is provided on the outer side of each limiting piece 201. One end of the spring 202 is fixedly connected to the inner wall of the gate 120, and the other end of the spring 202 is fixedly connected to the limiting piece 201. A protrusion 203 is also fixedly installed on the outer side of the baffle 200. A push plate 204 is fixedly installed on the outer side of the housing 140. The push plate 204 and the protrusion 203 intermittently abut against each other.

[0036] A pipe 210 connected to the sand flow outlet 190 is installed on the outside of the gate 120. One end of the pipe 210, which is fixedly connected to the gate 120, is set as a foldable fan-shaped pipe to avoid the end of the pipe 210 from obstructing the rotation of the gate 120. A sandbag 220 is connected to the outlet of the pipe 210. The sandbag 220 is a huge woven bag. Water is sprayed at the bottom of the river through the nozzle 180 to shake up the sediment deposited at the bottom of the river. The baffle 200 is opened so that the sediment flows with the water through the sand flow outlet 190 and the pipe 210 into the sandbag 220. A pool can be set up next to the river and the sandbag 220 can be placed in the pool. The river water mixed with a large amount of sediment flows into the sandbag 220. The sediment is intercepted and collected in the sandbag 220, while the river water flows through the sandbag 220 into the pool. The water in the pool can be introduced back into the river.

[0037] A turbine 230 is rotatably mounted at the inlet end of pipe 210. A first drive wheel 231 is coaxially mounted on the side of the turbine 230. The first drive wheel 231 is located inside the gate 120. A second drive wheel 232 is also rotatably mounted inside the gate 120. A first belt 233 is fitted between the first drive wheel 231 and the second drive wheel 232. The first belt 233 is located inside the gate 120. A third drive wheel 234 is coaxially mounted on the outside of the second drive wheel 232. A fourth drive wheel 235 is rotatably mounted on the outside of the gate 120. A second belt 236 is fitted between wheel 234 and the fourth transmission wheel 235. The second belt 236 is inserted into the side of the gate plate 120. The first transmission wheel 231 and the second transmission wheel 232 are located on the same vertical plane. The third transmission wheel 234 and the fourth transmission wheel 235 are located on the same horizontal plane. A turntable 237 is coaxially mounted on the outer side of the fourth transmission wheel 235. A push rod 238 is rotatably connected to the side of the turntable 237. A rack 239 is rotatably connected to the end of the push rod 238. The rack 239 is horizontally slidably mounted on the side wall of the gate plate 120.

[0038] A water outlet 170 near the sand outlet 190 is installed on the outside of the housing 140, and another water outlet 170 away from the sand outlet 190 is rotatably connected to the outside of the housing 140. A gear 240 that works with a rack 239 is installed at the end of the other water outlet 170 away from the sand outlet 190. The gear 240 and the rack 239 mesh intermittently. When the housing 140 drives the gear 240 to descend and approach the rack 239, the gear 240 meshes with the rack 239. When the housing 140 drives the gear 240 to rise and move away from the rack 239, the gear 240 disengages from the rack 239. The outer diameter 235 of the first transmission wheel 231, the second transmission wheel 232, the third transmission wheel 234 and the fourth transmission wheel increase in sequence. As the first transmission wheel 231 gradually transmits power to the fourth transmission wheel 235, the speed of the fourth transmission wheel 235 decreases relative to the first transmission wheel 231, so that the first transmission wheel 231 rotates at high speed while the fourth transmission wheel 235 rotates slowly and smoothly.

[0039] Through the above technical solution, when the water conservancy gate with water purification mechanism provided in this disclosure is in use, the floating impurities on the surface of the river are intercepted by the conveyor belt 132. The first motor 134 is started, which drives the conveyor roller 131 to rotate, thereby causing the conveyor roller 131 to drive the conveyor belt 132 to rotate upward. With the setting of the interception plate 133, when the conveyor belt 132 drives the interception plate 133 to move, the impurities floating on the water surface are scooped onto the conveyor belt 132. At the same time, the interception plate 133 also prevents the impurities on the conveyor belt 132 from sliding back into the river water. As the conveyor belt 132 rotates, the impurities on it are transported to the collection frame 135, which facilitates the collection and cleaning of impurities, thereby filtering and purifying the floating objects in the river water. When the telescopic end of the telescopic component 123 retracts inward, the upper end of the gate 120 flips downward. When the upper end of the gate 120 flips below the water surface, the river water can flow over the gate 120, and the flowing water is the upper layer of river water, which avoids the sediment deposited at the bottom of the river channel from crossing the gate 120 as much as possible, thus ensuring the cleanliness of the water flow. When the telescopic end of the telescopic component 123 extends outward to restore its original position, the downward-flipped gate 120 flips upward again to reset, thus blocking the river water again, thereby achieving the function of controlling the flow or blocking the river water. The silt in the river flows with the current to the side of the gate 120. When a large amount of silt settles at the bottom of the river in front of the gate 120, the second motor 153 is activated, causing the lead screw 152 to rotate. Through the threaded engagement between the lead screw 152 and the slider 151, the slider 151 causes the housing 140 to descend, which in turn causes the water outlet 170 to descend closer to the bottom of the river. Subsequently, water is pumped into the water outlet 170 through the water pipe 160, and the water is sprayed out towards the bottom of the river through the nozzle 180, thereby stirring up the silt deposited at the bottom of the river and mixing it with the lower layer of river water. Since some impurities may be covered by silt and pressed to the bottom of the river and cannot float, it is difficult to filter and remove these impurities, which can still affect the water purification effect. Therefore, when the silt deposited at the bottom of the river is stirred up, the impurities covered and pressed by the silt will also be directly exposed to the river water. These impurities are buoyed by the river water and tend to accumulate on the underside of the conveyor belt 132. At this time, the conveyor belt 132 is restarted, which causes the conveyor belt 132 to drive the interceptor plate 133 to scoop up the impurities accumulated on the underside of the conveyor belt 132. Due to the arc design of the interceptor plate 133, it is easy to scoop up the impurities onto the interceptor plate 133 and they are not easy to slip off. As the conveyor belt 132 rotates, the impurities are scooped out of the water by the interceptor plate 133 and fall onto the conveyor belt 132. Thus, while impacting the silt, these impurities can also be scooped up and filtered, further enhancing the impurity removal effect. At the same time, the housing 140 also drives the push plate 204 to descend, causing the descending push plate 204 to abut against the protrusion 203. This, in turn, presses down the baffle 200 and the limiting piece 201 by pressing down the protrusion 203, compressing and storing the spring 202, thereby opening the sand flow outlet 190. This allows the river water mixed with a large amount of silt to flow into the pipe 210 through the sand flow outlet 190. At this time, reference... Figure 9As shown, the housing 140 drives the gear 240 to contact and mesh with the rack 239. The water flow impacts the turbine 230, causing it to rotate. The rotating turbine 230 stirs the river water near the quicksand outlet 190, creating turbulence and accelerating the inflow of river water into the quicksand outlet 190. The turbine 230 drives the first transmission wheel 231 to rotate. Through the transmission of the first belt 233, the second transmission wheel 232 drives the third transmission wheel 234 to rotate. Through the transmission of the second belt 236, the fourth transmission wheel 235 drives the turntable 237 to rotate slowly. When the turntable 237 rotates, it continuously pushes and pulls the push rod 238, thereby causing the push rod 238 to rotate. 38 The push-pull rack 239 makes horizontal reciprocating motion. Through the meshing of gear 240 and rack 239, gear 240 rotates reciprocally within a certain angle, thereby driving water discharge 170 away from the sand outlet 190 to rotate. This causes the river water mixed with a large amount of silt away from the sand outlet 190 to rush back towards the sand outlet 190. This allows the river water to quickly and effectively carry the silt into the sand outlet 190. As a result, the river water carrying a large amount of silt flows into the sand bag 220 through the sand outlet 190 and pipe 210. The silt is intercepted and collected in the sand bag 220, while the river water flows out through the sand bag 220, thus achieving the purpose of filtering and collecting the silt in the river water. In summary, not only can the impurities floating on the water surface be removed and filtered by the impurity removal component 130, but the water discharge 170 can also lift the riverbed sediment while the impurity removal component 130 is used to further remove the impurities covered by sediment and pressed to the bottom of the river. This not only enhances the impurity removal effect, but also creates turbulence at the bottom of the water through the rotation of the turbine 230 and the oscillation of the water discharge 170, which quickly and effectively introduces the bottom river water carrying a large amount of riverbed sediment into the sandbag 220 for filtration and collection. Therefore, by combining the removal of floating impurities and the filtration and collection of sediment, water quality is purified in multiple ways, thereby improving the water purification effect. Finally, the pumping of water from water pipe 160 is stopped, and the second motor 153 reverses to reset housing 140, releasing the downward pressure of push plate 204 on protrusion 203. Under the action of spring 202's rebound force, baffle 200 moves upward to reset and closes sand outlet 190 again. Moreover, the silt collected in sandbag 220 can be used nearby for dam construction or agricultural planting, achieving the effect of resource reuse.
