Description

Technical Field

[0001] The invention belongs to the technical field of agricultural engineering, in particular to a gate capable of preventing siltation and clearing. Background Art

[0002] A sluice gate is a hydraulic device built into a body of water to intercept water flow, regulate water levels, and control flow. Sluice gates used for irrigation typically raise and lower the gate to open or close the water flow channel, thereby regulating water levels and flow.

[0003] When the gate is closed, the water flow will carry a large amount of silt and garbage and accumulate in front of the gate. If a large amount of silt and various impurities accumulate on the gate plate or in front of the gate, it will increase the resistance when the gate plate is raised and lowered, affecting the normal use of the gate. If the water volume is too large, the water flow carrying silt will cause a huge impact on the gate, which may cause damage to the gate and reduce the service life of the gate. If the deposited silt and river garbage are not cleaned up in time, when the gate is opened, the water quality of the irrigation water entering the farmland will decline, and some river garbage may be drawn into the gate groove, affecting the operation of the gate. For most of the existing gates used for canal irrigation, they lack automated cleaning of silt and floating objects accumulated in front of the gate. When cleaning the silt and garbage in front of the gate, a lot of manpower and material resources are required. Summary of the invention

[0006] When the silt base can carry the silt and rise to the lower edge of the silt cleaning plate and the raised silt base is not lower than the embankment of the canal or river, the silt cleaning plate clears the silt on the silt base out of the canal or river by moving left and right.

[0007] When the sedimentation base can carry the sediment to rise to the lower edge of the sediment cleaning plate and the risen sedimentation base is lower than the dam of the water channel or river, or when the sediment cleaning plate can fall onto the sedimentation base, the sediment cleaning plate clears the sediment on the sedimentation base from the water inlet side of the gate by moving left and right.

[0008] The bottom of the sediment cleaning plate has a curvature, small holes are arranged on the sedimentation base, and reinforcing ribs are installed at the bottom of the sedimentation base.

[0009] A water pump is arranged between the gate drainage structure and the gate silt cleaning structure. The water outlet of the cleaning pipe provided on the water pump is at the same height as the lower edge of the sediment cleaning plate in the working state. The water flow provided by the water pump can cooperate with the sediment cleaning plate to clear the sediment on the sedimentation base.

[0010] There is only one water outlet. The cleaning pipe can make the water outlet of the cleaning pipe face the side of the bottom bracket of the gate just by bending three times.

[0011] The sedimentation base is fixedly installed at the bottom of the second gate plate, and the lower part of the second gate plate is a grid structure, and the grid structure can intercept sundries in the water when the gate discharges water.

[0012] A vertical row of barbs is arranged on one side of the sediment cleaning plate close to the second gate plate, and the barbs can hook and take away the sundries intercepted by the grid structure.

[0014] A solar panel is arranged on the top of the gate drainage structure or the gate silt cleaning structure, and a storage battery is arranged in the gate drainage structure or the gate silt cleaning structure. The solar panel can convert solar energy into electrical energy and store it in the storage battery, and the storage battery can supply power to the motors and water pumps supporting the gate drainage structure and the gate silt cleaning structure.

[0018] The present invention has the following advantages compared with the prior art: The gate for channels or rivers provided by the present invention is used to solve the problem that existing equipment cannot automatically remove a large amount of sediment, garbage, and river floating objects accumulated in front of the gate.

When the gate is closed, it can clean up the sediment and river floating objects at the river channel in front of the gate, and when the gate is opened to release water, it can clean up the sediment scattered in front of the gate; in the closed state of the gate, some fine sand grains accumulated on the sedimentation base of the gate silt cleaning structure will flow down from the dense small holes on the base and be scattered in the river channel in front of the gate. Since these sand grains are relatively small, they will flow away from the gate area along with the flow of water after the gate is opened to release water. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manner

[0024] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments.

[0025] As Figures 1-6 shown, a gate capable of preventing blockage and cleaning silt includes a gate drainage structure 1. A gate silt cleaning structure 2 is provided on the water inlet side of the gate drainage structure 1. The gate silt cleaning structure 2 includes a second gate plate 204, a sediment cleaning plate 209 and a siltation base 211. The sediment cleaning plate 209 is located on the front side of the second gate plate 204 and the siltation base 211 is located directly below the sediment cleaning plate 209. The second gate plate 204 can intercept sediment and garbage in water on the water inlet side of the gate, and the falling sediment and garbage in water accumulate on the siltation base 211 to form silt deposits. The lower edge of the sediment cleaning plate 209 and the top surface of the siltation base 211 can be adjacent, and the sediment cleaning plate 209 can move left and right relative to the siltation base 211, so as to remove the silt deposits on the siltation base 211.

[0026] Regarding the adjacency between the sediment cleaning plate 209 and the silt accumulation base 211, there are three cases, including the sediment cleaning plate 209 being lifted independently, the silt accumulation base 211 being lifted independently, and both the sediment cleaning plate 209 and the silt accumulation base 211 being able to be lifted. If considering the adjacency based on the direction of the silt, there are mainly the following two cases: First, when the silt accumulation base 211 can carry the silt and rise to the lower edge of the sediment cleaning plate 209 and the risen silt accumulation base 211 is not lower than the dam of the water channel or river, the sediment cleaning plate 209 clears the silt on the silt accumulation base 211 out of the water channel or river through left - right movement; Second, when the silt accumulation base 211 can carry the silt and rise to the lower edge of the sediment cleaning plate 209 and the risen silt accumulation base 211 is lower than the dam of the water channel or river, or when the sediment cleaning plate 209 can descend onto the silt accumulation base 211, the sediment cleaning plate 209 clears the silt on the silt accumulation base 211 from the water inlet side of the gate through left - right movement.

[0027] As Figure 6 shown, in order to improve the efficiency of the sediment cleaning plate 209, the bottom of the sediment cleaning plate 209 is set to a structure with a curvature; the purpose of arranging small holes on the silt accumulation base 211 is to let the water flow carry some fine sand grains away through the small holes; reinforcing ribs are installed at the bottom of the silt accumulation base 211, which can make the structure of the silt accumulation base 211 stable.

[0028] To improve the cleaning efficiency, as Figures 1-2 shown, a water pump 4 is arranged between the gate drainage structure 1 and the gate silt cleaning structure 2. The water outlet 216 of the cleaning pipe 5 set on the water pump 4 is at the same height as the lower edge of the sediment cleaning plate 209 in the working state. The water flow provided by the water pump 4 can cooperate with the sediment cleaning plate 209 to clear the silt on the silt accumulation base 211. Regarding the setting of the water pump 4, it is preferably set on the connecting block 3 that fixedly connects the gate drainage structure 1 and the gate silt cleaning structure 2, and the cleaning pipe 5 is also arranged relying on the connecting block 3.

[0029] As Figure 4 shown, the silt accumulation base 211 is fixedly installed at the bottom of the second gate plate 204 and the lower part of the second gate plate 204 is a grid structure 210. Such a structural setting ensures that the water flow can be cleaned even when discharging water, because the grid structure 210 can intercept the sundries in the water when the gate discharges water; to cooperate with the grid structure 210, a row of vertical barbs is arranged on the side of the sediment cleaning plate 209 adjacent to the second gate plate 204, and the barbs can hook and carry away the sundries intercepted on the grid structure 210.

[0030] As Figures 1-5As shown, the above-mentioned gate drainage structure 1 is equipped with a first motor 105. The first motor 105 drives the lead screw nut mechanism through a gear structure to drive the first gate plate 107 to lift and lower. The driving mechanism of the first gate plate 107 is arranged in the upper closed area of the gate drainage structure 1. The above-mentioned gate silt cleaning structure 2 is equipped with a second motor 213. The second motor 213 drives the lead screw nut mechanism through a gear structure to drive the second gate plate 204 to lift and lower. The above-mentioned sediment cleaning plate 209 is equipped with a third motor 205. The third motor 205 drives the lead screw nut mechanism through a gear structure to drive the sediment cleaning plate 209 to translate left and right. The lifting drive part and the translation drive part of the gate silt cleaning structure 2 are arranged in the loading bracket 203 at the upper part of the gate silt cleaning structure 2.

[0031] As Figures 1-2 shown, a solar panel 103 is provided at the top of the above-mentioned gate drainage structure 1 or the gate silt cleaning structure 2, and a storage battery is arranged in the gate drainage structure 1 or the gate silt cleaning structure 2. The storage battery is arranged in an area that will not be submerged by water. The solar panel 103 can convert solar energy into electrical energy and store it in the storage battery, and the storage battery can supply power to the motors and pumps 4 that are supporting facilities for the gate drainage structure 1 and the gate silt cleaning structure 2.

[0032] As Figures 1-4 shown, a first handle 102 is configured on the driving component of the first gate plate 107 of the above-mentioned gate drainage structure 1; a second handle 201 is configured on the driving component of the second gate plate 204; a third handle ********** is configured on the driving component of the sediment cleaning plate 209. Configuring the handles enables the sluice gate to be manually driven even without power, ensuring the normal operation of the gate. Embodiment

[0033] Reference Figure 1 、 Figure 7 It should be noted that there is an incomplete expression "**********" in the translation of . Please check and correct the original text if necessary., the present invention provides a gate capable of preventing blockage and clearing silt, which can be used in the field of agricultural engineering technology. The gate includes a gate drainage structure 1, a gate silt cleaning structure 2, a connecting block 3, a water pump 4, and a cleaning pipe 5. The gate mentioned in the present invention can be deployed in the irrigation channels in farmland. The flow of water is controlled by the lifting of the first gate plate 107 in the gate drainage structure 1. The silt and river floating objects accumulated on the water inlet side of the gate are cleared through the gate silt cleaning structure 2. The water pump 4 sprays water through the cleaning pipe 5 onto the gate silt cleaning structure 2 to assist in clearing the silt and cleaning the gate silt cleaning structure 2 at the same time. The specific process is as follows: Since a large amount of sediment accumulates at the small holes on the silt accumulation base 211 of the gate silt cleaning structure 2, and these sediments block the small holes and cannot be completely cleaned by relying on the sediment cleaning plate 209. So when the silt accumulation base 211 rises to the same height as the bottom of the sediment cleaning plate 209 and is directly opposite to the water outlet 216 of the cleaning pipe 5, the water pump 4 will spray a large amount of water. Due to the large kinetic energy of the water flow, the water flow will splash and reflect after hitting the bottom support 214 on the other side. Among them, part of the water flow splashing onto the silt accumulation base 211 will carry some fine sand grains and flow out downward from the small holes on the silt accumulation base 211 to clean the gate silt cleaning structure 2 of the gate. The gate drainage structure 1 and the gate silt cleaning structure 2 are fixedly connected together by four connecting blocks 3, and the water pump 4 is installed on the bottommost connecting block 3. The connecting block 3, the water pump 4, and the cleaning pipe 5 do not affect the entry of water flow.

[0034] The above-mentioned gate can be deployed in irrigation channels or rivers. The flow of water is controlled by the lifting of the gate plate in the gate drainage structure 1, and the silt and garbage accumulated in front of the gate are cleared through the gate silt cleaning structure 2. And the water pump 4 and the cleaning pipe 5 assist in clearing the sediment accumulated on the gate.

[0035] The gate drainage structure 1 in the gate is responsible for controlling the water flow, which is mainly achieved by the up and down movement of the first gate plate 107 inside the gate housing 106. For specific reference Figure 1 , Figure 2 , Figure 3 , the present invention includes a gate drainage structure 1. The gate drainage structure 1 includes a gate housing 106. Sliding grooves are assembled on both sides of the inner cavity of the gate housing 106. The first gate plate 107 can smoothly move up and down along the sliding grooves. The gate drainage structure 1 can control the lifting of the first gate plate 107 through the internal drive mechanism, so as to realize the regulation of the water flow.

[0036] Reference Figure 3 , Figure 5, the driving mechanism of the gate drainage structure 1 is the first motor 105. The output shaft of the first motor 105 is connected to the motor gear 108, which meshes with the gear at the bottom of the first lead screw 101. The first motor 105 transmits power to the first lead screw 101. The first lead screw 101 is equipped with a first moving block 104, and the first moving block 104 is fixedly installed on the first gate plate 107. When the gate needs to be opened, the first motor 105 is started. The motor gear 108 at the bottom of the first motor 105 drives the first lead screw 101 to rotate, and the first moving block 104 and the first gate plate 107 then move axially upward along the first lead screw 101. When the first gate plate 107 rises to a certain position, the gate is opened. Conversely, when closing the gate, the first motor 105 is started. The motor gear 108 at the bottom of the first motor 105 drives the first lead screw 101 to rotate in the reverse direction, and the first moving block 104 and the first gate plate 107 then move axially downward along the first lead screw 101. When the first gate plate 107 completely descends to the bottom, the gate is closed.

[0037] The top of the first lead screw 101 is connected to the first handle 102. Rotating the first handle 102 causes the first lead screw 101 to rotate as the first handle 102 turns, thereby driving the first moving block 104 to move axially along the first lead screw 101. This avoids the abnormal operation of the gate in the absence of power supply. Even without power, the gate can still be manually driven to operate by rotating the first handle 102.

[0038] Reference Figure 1 , Figure 2 , Figure 3 , the energy supply of the gate mainly depends on the solar panel 103 installed on the top of the gate housing 106 in the gate drainage structure 1. The solar panel 103 is connected to the storage battery of the gate. On sunny days, the solar panel 103 can convert solar energy into electrical energy and store it in the storage battery to achieve independent power supply for the gate, ensuring the normal operation of the motors and the water pump 4 inside the gate drainage structure 1 and the gate silt cleaning structure 2.

[0039] Reference Figure 1 , Figure 2 , Figure 4, the gate silt cleaning structure 2 in the gate is responsible for cleaning the sediment accumulated in front of the gate and the floating debris in the river channel. The bottom bracket 214 belongs to the gate sediment cleaning structure 2. The bottom bracket 214 can support the loading bracket 203 on the gate cleaning structure 2, improving the stability of the entire gate. The bottom bracket 214 is connected to the gate housing 106 through four connecting blocks 3, which improves the integrity and integration of the gate. A third motor 205 is installed on the inner side wall of the loading bracket 203. The third motor 205 is meshed and connected to the gear structure at one end of the third lead screw 208 through the gear structure of the output shaft part. When the third motor 205 is started, the gear at the bottom of the motor drives the third lead screw 205 to rotate. The third moving block 212 on the third lead screw 205 drives the sediment cleaning plate 209 to move horizontally left and right along the third lead screw 208, so as to sweep the sediment on the sedimentation base 211 to a place outside the water channel.

[0040] Reference Figure 4 , Figure 6 , the sediment cleaning plate 209 is connected to the third moving block 212 through a connecting piece 215. There is a chute at the bottom of the loading bracket 203 to facilitate the sliding of the connecting piece 215 in the chute; the sediment cleaning plate 209 is connected to the connecting piece 215 by screws, which is convenient for the subsequent disassembly and replacement of the sediment cleaning plate 209. The bottom of the adopted sediment cleaning plate 209 has a curvature, which can shovel sediment, floating debris in the river channel, weeds, etc. from the sedimentation base 211 to prevent sediment from accumulating in front of the gate. At the same time, there is a vertical row of small barbs on one side of the sediment cleaning plate 209 close to the second gate plate 204, which can hook and tear floating debris and garbage in the water such as plastic bags, facilitating the cleaning of garbage and floating debris in the water.

[0041] Reference Figure 4 , a second motor 213 is also installed at the bottom of the loading bracket 203 to control the rising and falling of the second gate plate 204 and the sedimentation base 211. The second motor 213 is meshed and connected to the gear structure at the bottom of the second lead screw 202 through the gear structure of its output shaft bottom. When the second motor 213 rotates, it drives the second lead screw 202 to rotate through the gear. The second moving block 207 and the connected second gate plate 204 move axially up and down along with the second lead screw 202.

[0042] Reference Figure 4, a silt base 211 for collecting sediment is installed at the bottom of the second gate 204. The silt base 211 usually stays at the bottom of the gate. Since the sediment will be blocked by the second gate 204, a large amount of sediment will be deposited on the silt base 211. There are many small holes on the silt base 211, and the water flow will carry some fine sand grains and flow away from the small holes on the silt base 211, but large particle substances such as sediment cannot pass through the small holes and will accumulate on the silt base 211. Reinforcing ribs are also installed at the bottom of the silt base 211, which can make the structure of the silt base 211 stable.

[0043] A grille structure 210 is installed on the second gate 204. The grille structure 210 can effectively block the sediment carried in the water flow, filter the water flow, and can also effectively intercept the garbage, floating objects and large particle substances suspended in the water flow, preventing sediment from accumulating in front of the first gate 107 of the gate drainage structure 1. The combination of the grille structure 210, the second gate 204 and the silt base 211 will block a large amount of river floating objects and sediment, which helps to clean the water flow, reduce the contact between the silt and the first gate 107, and reduce its impact on the gate.

[0044] Reference Figure 1 、 Figure 2 、 Figure 7 、 Figure 8 , the water pump 4 is installed on the connection block 3 at the bottom between the gate drainage structure 1 and the gate silt cleaning structure 2. The connection block 3 is connected to the bottom bracket 214 of the gate silt cleaning structure 2, so the connection block 3 and the water pump 4 will not block the entry of water flow when the gate is opened. An upper part of the water pump 4 is connected with a cleaning pipe 5. The cleaning pipe 5 is bent three times and is led out from a small hole on the bottom bracket 214 at the same height as the bottom of the sediment cleaning plate 209. The water flow sprayed by the water pump 4 helps to clean the sediment deposited on the silt base 211. At the same time, the silt base 211 is assembled on the second gate 204, so a part of the silt base 211 is in contact with the bottom bracket 214, and the sediment cleaning plate 209 cannot clean this position, and a large amount of sediment will still accumulate at this position of the silt base 211. Since the water outlet 216 of the cleaning pipe 5 is facing this part of the position, due to the large kinetic energy when a large amount of water flow rushes out from the water outlet 216, a part of the sediment, plastic bags, etc. accumulated at this part will rush towards the other bottom bracket 214 along the water flow direction, and will sputter and move outwards after hitting the bottom bracket 214, reaching the area that the sediment cleaning plate 209 can clean, realizing the auxiliary cleaning of sediment by the water pump.

[0045] Reference Figure 2 、 Figure 4 、 Figure 7 、 Figure 8, when the siltation base 211 reaches below the sediment cleaning plate 209, the water pump 4 will start, and a large amount of water flow will rush out from the water outlet 216. The water flow will wash the sediment and river floating objects that the sediment cleaning plate 209 cannot scrape to the vicinity of the sediment cleaning plate 209, facilitating the sediment cleaning plate 209 to clean up all the sediment. At the same time, when the water flow hits the siltation base 211, it will carry part of the sediment and flow out from the small holes on the siltation base 211.

[0046] Reference Figure 4 , one end of the third lead screw 208 is a gear structure, and the other end is connected to the third handle 206. When the third handle 206 is rotated, the third lead screw 208 will also rotate, and drive the third moving block 212 to move horizontally along the third lead screw 208 axially. Similarly, the bottom of the second lead screw 202 is a gear structure, and the top is connected to the second handle 201. When the second handle 201 is rotated, the second lead screw 202 will also rotate, and drive the second moving block 207 to move vertically along the second lead screw 202. This ensures that in the absence of power, the normal operation of the gate sediment cleaning structure can be controlled by rotating the handle.

[0047] The usage process of a gate capable of preventing blockage and dredging provided by the embodiment of the present invention is as follows: Place the gate provided by the present invention in the river channel, and the gate will block the flow of water. The first gate plate 107 has not risen, and the gate is still in the closed state. At this time, if a large amount of sediment, garbage, and floating objects accumulate in front of the gate, the siltation base 211 of the silt cleaning structure 2 of the gate will carry a large amount of sediment and garbage and rise. When it reaches the place where the sediment cleaning plate 209 can clean, the siltation base 211 will not be lower than the dam; start the sediment cleaning plate 209, and the sediment cleaning plate 209 will clean the sediment and garbage onto or outside the dam. At the same time, the water pump 4 will eject water flow, and the water flow will wash the siltation base 211 and wash the sediment to the vicinity of the sediment cleaning plate 209 for easy cleaning. When the gate needs to be opened, the first gate plate 107 can be moved upward. When the first gate plate 107 rises to a certain height, the gate is completely opened, and the water flow will pour in from below the grid structure 210 and the first gate plate 107. The gate silt cleaning structure 2 and the gate drainage structure 1 provided by the present invention can both be controlled by an electric motor. If there is a situation of insufficient energy, the operation of the gate can be controlled by manually rotating the handle.

[0048] The gate for a channel or river provided by the present invention is used to solve the problem that existing equipment cannot automatically remove a large amount of sediment, garbage, and river floating objects accumulated in front of the gate. The gate effectively blocks the floating objects in the water and automatically removes the sediment accumulated at the gate, thereby preventing the sediment and river floating objects from accumulating in front of the gate for a long time and affecting the daily use of the gate; aiming to increase the service life of the gate, reduce the harm of sediment deposition to the normal use of the gate, and thus improve the water inlet and drainage efficiency of the gate.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the technical solutions of the embodiments of the present invention. The technologies not involved in the present invention can all be realized through the prior art.
