Description

Technical Field

[0001] The present invention relates to the technical field of water control gates, and particularly relates to a water control gate with an anti-blocking mechanism. Background Art

[0002] A water control gate is used to regulate the upstream water level and control the discharge flow of water, also known as a river-blocking water control gate. The main functions of the water control gate are as follows: during the dry season, the gate is closed to raise the upstream water level to meet the requirements of shipping, irrigation, power generation water diversion, and urban water supply; during the flood season, the gate is opened to discharge flood, so that the upstream water level does not exceed the flood control limit water level, and at the same time, the discharge flow is controlled so that it does not exceed the safe discharge capacity of the downstream river channel.

[0003] Due to the irregular opening and closing interval time of the water control gate, there is a situation where the water control gate is closed for a long time. Sludge and other impurities will accumulate on the front of the gate and in the lifting track upstream of the water control gate, and some will also adhere to the gate, resulting in the situation that the water control gate is not easy to open vertically.

[0004] The above information disclosed in the background art section is only used to strengthen the understanding of the background of the present disclosure. Therefore, it may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Invention

[0005] The purpose of the present invention is to design that before the gate is opened vertically, the water pressure upstream is first used to push the gate to move horizontally to create a gap, and the water flow is used to wash away the sludge and other impurities accumulated or adhered in the front of the gate and in the lifting track before the gate is fully opened, so as to solve the above deficiencies in the technology.

[0006] To achieve the above purpose, the present invention provides the following technical solution: a water control gate with an anti-blocking mechanism, including a guiding gate, a gate leaf vertically slidably installed in the guiding gate, two vertical chutes in the guiding gate, and a hoisting device for driving the gate leaf to lift and lower in the two vertical chutes. The distance between the two vertical chutes is greater than the width of the gate leaf, and the width of the vertical chute is greater than the thickness of the gate leaf. The gap between the gate leaf and the vertical chute forms a pressure relief chamber. The hoisting device includes a vertical component that vertically moves on the guiding gate, and a horizontal component fixedly installed on the top of the gate leaf. The horizontal component is horizontally slidably connected in the vertical component along the thickness direction of the gate leaf. A pushing plate is also vertically slidably installed in the two vertical chutes. When the pushing plate is in contact with both the back of the gate leaf and one side of the vertical chute at the same time, the front of the gate leaf is in contact with the other side of the vertical chute to block the bottom of the guiding gate. By pulling the pushing plate away from the back of the gate leaf and no longer squeezing the gate leaf against one side of the vertical chute, the sludge and water blocking the front of the gate leaf are oppressed to separate the gate leaf from one side of the vertical chute, and the water can also drive the sludge and the like to be discharged to the back of the guiding gate through the pressure relief chamber, reducing the amount of sludge adhering to the gate leaf.

[0007] Preferably, the vertical component includes a first threaded rod passing through the top of the guiding gate, a first rotating member for driving the lifting of the first threaded rod, a connecting member fixedly connected to the bottom of the threaded rod, a horizontal sliding groove formed in the connecting member, and a guiding rod fixedly connected to the top of the connecting member. A guiding groove is further formed in the top of the guiding gate along the thickness direction of the gate leaf, and the guiding rod is slidably connected to the guiding groove.

[0008] Preferably, the horizontal component includes a connecting shaft slidably connected to the horizontal sliding groove, and a connecting block fixedly connected between the connecting shaft and the top of the gate leaf.

[0009] Preferably, both ends of the connecting shaft penetrate through the horizontal sliding groove, and first rollers are rotatably installed at both ends of the connecting shaft. When the pushing plate contacts the first rollers, the pushing plate does not fit against the back surface of the gate leaf.

[0010] Preferably, a plurality of second rollers are rotatably installed on the back surface of the gate leaf. When the pushing plate contacts the second rollers, the pushing plate simultaneously contacts the first rollers.

[0011] Preferably, a U-shaped rubber sheet is fixedly installed on the front surface of the gate leaf.

[0012] Preferably, a roller shaft is fixedly installed on the back of the guiding gate. When the pushing plate simultaneously contacts the second rollers and the roller shaft, the U-shaped rubber sheet is squeezed against the guiding gate to form a seal.

[0013] Preferably, a second threaded rod and a smooth rod are fixedly installed on the top of the pushing plate. The top ends of the second threaded rod and the smooth rod penetrate through the top of the guiding gate, and a second rotating member for driving the lifting of the second threaded rod is fixedly installed on the top of the guiding gate.

[0014] Preferably, a slope is formed at the bottom of the inner cavity of the guiding gate, and an inclined block cooperating with the slope is fixedly installed at the bottom of the gate leaf. When the slope fits against the inclined block, the U-shaped rubber sheet fits against the inner wall of the guiding gate. When the U-shaped rubber sheet is separated from the guiding gate, a flushing groove is formed between the slope and the inclined block.

[0015] In the above technical solution, the technical effects and advantages provided by the present invention are as follows: 1. By pulling out the pushing plate between the roller shaft and the gate leaf in the present invention, the gate leaf will move horizontally towards the back surface under the thrust of water pressure, thereby exposing the flushing groove and the pressure relief chamber, allowing water to flow at high speed through the narrow gap, and flushing away impurities such as silt from the front of the gate and the lifting track. 2. Before full closing, the invention only moves the gate leaf under the guiding gate, but does not insert the pushing plate between the roller shaft and the gate leaf, so that there are scouring grooves and pressure relief chambers in the gate leaf. At this time, the high-speed flowing water can wash away impurities such as silt accumulated in the lifting track during long-term gate opening, ensuring the sealing performance during closing and facilitating closing. 3. At the same time, when the gate leaf of the invention seals and blocks with the guiding gate, it does not completely move vertically, but finally moves horizontally for sealing and blocking, so that impurities such as silt upstream cannot enter the lifting track through the front of the gate leaf, and only impurities such as silt downstream can enter the lifting track through the back of the gate leaf, reducing the amount of silt entering the lifting track on one side. 4. Compared with directly driving the gate leaf to lift in the prior art, the invention utilizes water pressure as the preliminary power during gate opening, so that the gate first moves horizontally to expose a gap. After the silt and other substances affecting gate opening are washed away, the gate is then opened vertically, thereby preventing the situation where silt and other substances affect gate opening.

[0019] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0020] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the specification drawings and specific implementation modes.

[0021] The present invention provides a kind of water conservancy gate with an anti-blocking mechanism as Figure 1-7 shown, which includes a guide gate 1 embedded in concrete. The guide gate 1 is rectangular and hollow, and vertical chutes 3 are respectively opened on both sides of the inner wall of the guide gate 1. A gate leaf 2 is placed in the vertical chute 3. We design the width of the vertical chute 3 to be greater than the style of the gate leaf 2, so that the gate leaf 2 can move horizontally along the thickness direction. At the same time, we design the width of the gate leaf 2 to have a gap with the two vertical chutes 3, so that the gap between the gate leaf 2 and the vertical chute 3 forms a pressure relief chamber 5. In this way, when the gate leaf 2 does not fit with the guide gate 1 to form a seal, water can carry silt through the pressure relief chamber 5 to the back of the guide gate 1, reducing the amount of silt adhering and accumulating on the front of the gate leaf 2, thus making it easy to open the gate; at the same time, we open a slope 13 at the bottom of the inner cavity of the guide gate 1, and fixedly install an inclined block 14 at the bottom of the gate leaf 2 that cooperates with the slope 13. When the inclined block 14 and the slope 13 do not fit, a scouring groove 15 will be formed. In this way, before closing the gate, the water flow will pass through the pressure relief chamber 5 and the scouring groove 15 to wash away the impurities accumulated in the guide gate 1 after opening the gate with high-velocity water, preventing the gate from closing tightly; To ensure that the gate leaf 2 can be lifted vertically, we fixedly install a first rotating member 4a2 on the guiding gate 1, and threadedly connect a first threaded rod 4a1 inside the first rotating member 4a2. Let the first threaded rod 4a1 penetrate through the guiding gate 1 and fixedly install a connecting member 4a3 at the end. At the same time, a horizontal sliding groove 4a4 is formed inside the connecting member 4a3. Because of the pressure relief chamber 5 designed between the gate leaf 2 and the vertical sliding groove 3, the vertical sliding groove 3 cannot restrict the rotation of the gate leaf 2. Therefore, we fixedly install a guiding rod 4a5 on the top of the connecting member 4a3, and open a guiding groove 4a6 on the top of the guiding gate 1 for the guiding rod 4a5 to slide and connect along the thickness direction of the gate leaf 2. These structures constitute the vertical component 4a. To ensure that the gate leaf 2 can move horizontally, we slidably install a connecting shaft 4b1 in the guiding groove 4a6, and fixedly install a connecting block 4b2 between the gate leaf 2 and the connecting shaft 4b1. Let both ends of the connecting shaft 4b1 penetrate through the horizontal sliding groove 4a4 and rotatably install a first roller 4b3. These components constitute the horizontal component 4b; To drive the gate leaf 2 to move horizontally, a second threaded rod 10 and a smooth rod 11 penetrate through the guiding gate 1. A pushing plate 6 is fixedly installed at the bottom of the second threaded rod 10 and the smooth rod 11 together. A second rotating member 12 for driving the second threaded rod 10 to lift vertically is fixedly installed on the guiding gate 1. To reduce the friction between the pushing plate 6 and the gate leaf 2 and the guiding gate 1, we rotatably install a roller shaft 9 on the back of the guiding gate 1, and fixedly install a second roller 7 on the back of the gate leaf 2. In this way, when both sides of the pushing plate 6 contact the second roller 7 and the roller shaft 9 respectively, the gate leaf 2 can be pushed to move horizontally. At the same time, to ensure the sealing performance between the gate leaf 2 and the guiding gate 1, we fixedly install a U-shaped rubber sheet 8 on the front of the gate leaf 2 to adapt to the bottom shape of the guiding gate 1; After this water gate is opened and works for a period of time, if it needs to be closed, first drive the first rotating member 4a2 to control the first threaded rod 4a1 to descend. The first threaded rod 4a1 will drive the gate leaf 2 to descend through the connecting member 4a3, the connecting shaft 4b1 and the connecting block 4b2. When the U-shaped rubber sheet 8 moves horizontally to block the guiding gate 1, stop driving the first rotating member 4a2. At this time, the water can only pass through the pressure relief chamber 5 and the scouring groove 15 and be discharged to the back of the guiding gate 1 to the downstream. The flow rate of the water passing through the guiding gate 1 is higher than that when the water level relative to the gate leaf 2 does not drop. The flow rate of the water will increase, so as to better wash away the silt and other impurities staying and precipitating in the guiding gate 1, preventing the situation of difficult closing or water leakage after closing; Then drive the second rotating member 12 to control the second threaded rod 10 to descend. The second threaded rod 10 will drive the pushing plate 6 to descend. After the pushing plate 6 contacts the first roller 4b3, the second roller 7 and the roller shaft 9, it will push the gate leaf 2 closer to the guiding gate 1. The gate leaf 2 will drive the connecting shaft 4b1 to slide in the horizontal sliding groove 4a4 until the U-shaped rubber sheet 8 is closely attached to the guiding gate 1 to achieve sealing and blocking; After closing the gate, impurities such as silt will gradually accumulate on the front of the gate leaf 2. When it is necessary to open the gate, reverse-drive the second rotating member 12 to pull out the push plate 6 from between the roller shaft 9 and the second roller 7. At this time, under the action of water pressure, the gate leaf 2 will be pushed towards the roller shaft 9 side, separating the U-shaped rubber sheet 8 from the guiding gate 1, and the flushing groove 15 and the pressure relief chamber 5 will appear again. At this time, the water flow will drive the silt to gradually pass through the pressure relief chamber 5 and the flushing groove 15 from top to bottom, and thus be discharged downstream. After there is no longer water flushing out silt downstream, it means that there is not much adhered silt and other impurities on the gate leaf 2. At this time, drive the first rotating member 4a2 again to lift the gate leaf 2. Compared with the prior art where silt and other impurities adhere to the gate leaf 2, it is easier to open the gate.

[0022] Importantly, it should be noted that the construction and arrangement of the present application shown in multiple different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who refer to this disclosure should easily understand that many modifications are possible (for example, changes in the dimensions, scales, structures, shapes and proportions of various elements, and parameter values (such as temperature, pressure, etc.), installation arrangements, use of materials, colors, orientations, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in this application.
