Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a water conservancy opening and closing gate used in water conservancy project construction. Background Art

[0002] Water conservancy project construction is an engineering activity used to control and allocate natural surface water and groundwater. It achieves flood control, irrigation, water supply, power generation and other purposes by constructing various hydraulic structures such as dams, channels, and pumping stations. In water conservancy projects, water flow control is crucial. When it is necessary to regulate water flow and control water levels, hydraulic gates can be flexibly opened or closed according to actual conditions. For example, during the reservoir water filling stage, closing the gates can block the water flow and allow the reservoir water level to rise. Hydraulic gates can also block water flow and play a key role in flood control. When floods occur, closing the gates prevents flooding in downstream areas. During the dry season, water release can be controlled to ensure the water supply for irrigation, water supply and other needs.

[0003] In the existing technology, due to natural factors (such as branches and leaves falling into the water body) and human factors (such as discarded plastic, paper and other garbage entering the river), debris will flow with the water in the water conservancy facilities, and some gates lack an effective garbage collection and cleaning mechanism, which makes it difficult for some gates to collect and clean the garbage in the water, thereby affecting the normal closing of the gate, resulting in a decrease in sealing, thereby reducing the water flow control accuracy, affecting the water storage, flood discharge and other functions of the water conservancy project. For this reason, a water conservancy gate for water conservancy project construction is proposed to solve the above problems. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a water conservancy opening and closing gate for use in water conservancy project construction, aiming to improve the problem that some gates in the existing technology are difficult to collect and clean garbage in the water.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A water conservancy opening and closing gate for water conservancy project construction comprises a gantry, the top of the gantry is fixedly connected to two hoists, the output end of the hoists is fixedly connected to a steel rope, the other end of the steel rope is fixedly connected to a connector, the bottoms of the two connectors are fixedly connected to a gate, the outer side of the gate is detachably connected to an interception net, the outer wall of the gate is movably connected to a rotating column, the outer wall of the rotating column is fixedly connected to two locking blocks, the other end of the rotating column is fixedly connected to a turning handle, the outer wall of the turning handle is fixedly connected to two locking columns, the bottom of the gantry is fixedly connected to a base, and the top of the base is fixedly connected to a support assembly for enhancing the gate's anti-punching ability;

[0022] 1. In the present invention, when the gate is closed, the interception net on the outside can block large debris outside the gate, while the storage trough collects small debris. When the debris on the interception net accumulates to a certain extent, the locking column can be separated from the gate by pulling the rotating column outward, and then the rotating column is rotated to separate the locking block from the interception net, so that the interception net can be easily dismantled, and the cleaning and maintenance of the interception net and the storage trough are convenient, which realizes the timely interception and cleaning of garbage in the water, effectively protects downstream water conservancy facilities, reduces equipment failure rate and maintenance costs, and maintains the water flow channel of the water conservancy project unobstructed, ensuring accurate water level control and water volume allocation.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1 、 Figure 3 、 Figure 4 The present invention provides an embodiment of a water conservancy gate for use in water conservancy project construction. The gate comprises a gantry 1, which serves as the support frame for the entire gate 5 structure and provides a stable support point for subsequent mechanisms. Two hoists 2 are fixedly connected to the top of the gantry 1. These hoists 2 provide power for the subsequent gate 5 mechanisms, ensuring smooth operation during opening and closing. A steel rope 3 is fixedly connected to the output end of the hoist 2. The steel rope 3 exhibits excellent flexibility and tensile strength, allowing it to withstand significant tensile forces without breaking during long-term use. A connector 4 is fixedly connected to the other end of the steel rope 3. This connector 4 connects the steel rope 3 to the subsequent mechanisms, ensuring effective force transmission during the lifting and lowering process. The bottoms of the two connectors 4 are fixedly connected to the gate 5, which is used to block water flow. Two slide grooves 18 are respectively defined on the inner walls of the gantry 1, providing a stable sliding track for the gate 5 to be raised and lowered. The outer walls of the gate 5 slide within the two slide grooves 18. This ensures the stability of the gate 5 during the lifting process, prevents it from deflecting or shaking, and disperses the pressure on the gate 5 to the entire portal frame 1, thereby increasing the overall structural strength.

[0033] The gate 5 is detachably connected to an interception net 6 on the outside. This net is used to intercept debris in the water flow. The gate 5 is provided with multiple storage slots on its exterior, allowing smaller debris to pass through the interception nets 6 and enter the slots, preventing them from spreading and accumulating in other areas of the water conservancy project and facilitating subsequent cleaning. The outer wall of the interception net 6 is detachably connected to the interior of the slots. When the slots contain excessive debris, the interception net 6 can be removed to clean the debris. A rotating column 7 is movably connected to the outer wall of the gate 5, providing a rotational foundation for subsequent mechanisms. Two locking blocks 8 are fixedly connected to the outer wall of the rotating column 7. The outer walls of the interception net 6 contact the outer walls of the locking blocks 8. Rotating the rotating column 7 causes the locking blocks 8 to engage with the interception net 6, thereby securing the interception net 6 to the outside of the gate 5. The interception net 6 can be unlocked by rotating the rotating column 7 in the opposite direction, allowing it to be easily removed for cleaning and maintenance. A handle 9 is fixedly connected to the other end of the rotating column 7, allowing the user to control the movement of the rotating column 7. Two locking posts 10 are fixedly connected to the outer wall of the turning handle 9. The other ends of the multiple locking posts 10 are detachably connected to the exterior of the gate 5. By pulling out the turning post 7 a certain length, the locking posts 10 are separated from the exterior of the gate 5, thereby unlocking the turning post 7 and allowing it to rotate. A base 11 is fixedly connected to the bottom of the gantry 1. The base 11 provides stable support for the entire gate 5 mechanism. The bottom of the base 11 is buried in the soil, thereby enhancing the stability of the entire gate 5 structure. A support assembly is fixedly connected to the top of the base 11 to enhance the gate 5's impact resistance.

[0034] Reference Figure 2 、 Figure 3 、 Figure 5 The support assembly includes multiple connecting plates 12, which are used to transmit and disperse forces from above to the base 11. The bottoms of the multiple connecting plates 12 are fixedly connected to the top of the base 11. A sleeve 13 is fixedly connected to the top of the connecting plates 12, providing a stable sliding path for the internal mechanism, thereby ensuring the accurate direction of force transmission. A spring 16 is fixedly connected to the inner wall of the bottom of the sleeve 13. When subjected to external pressure, the spring 16 deforms to absorb energy, thereby reducing the direct impact on the gate 5 and the gantry 1. The other end of the spring 16 is fixedly connected to a transmission column 14, which is used to transmit the impact force exerted on the gate 5 and the gantry 1. The outer wall of the transmission column 14 is slidably connected to the inner wall of the sleeve 13. When subjected to external force, the transmission column 14 moves up and down on the inner wall of the sleeve 13, ensuring that the transmission column 14 can move linearly along the axial direction of the sleeve 13 when subjected to force, while limiting its displacement in other directions, thereby ensuring effective force transmission and guidance. The other end of the transmission column 14 is fixedly connected to a connecting plate 2 15 , and the outer walls of the other sides of the multiple connecting plates 2 15 are fixedly connected to the outer wall of the portal frame 1 . The connecting plate 2 15 is used to transfer the impact force exerted on the portal frame 1 to the connecting plate 2 15 .

[0035] The top of the base 11 is detachably connected to a plurality of ground spikes 17, which are used to fix the entire gate 5 system to the ground. The bottom of the ground spike 17 is sharp and can be easily inserted into the soil, and provides additional support through its own shape and material properties. The bottoms of the plurality of ground spikes 17 are inserted into the soil to fix the entire gate 5. The top of the base 11 is fixedly connected to a sealing gasket 19, and the bottom of the gate 5 is in contact with the top of the sealing gasket 19. The sealing gasket 19 plays a role of sealing and buffering. When the gate 5 is closed, the sealing gasket 19 can fit tightly on the base 11, effectively preventing water leakage.

[0036] Working Principle: During operation, the hoist 2 can be controlled to drive the steel rope 3 to rise and fall, thereby driving the gate 5 to rise and fall along the chute 18. When the gate 5 descends, it comes into close contact with the sealing gasket 19, thereby providing a certain cushioning effect, reducing wear on the gate 5 itself and also acting as a seal, preventing water leakage from the bottom of the gate 5. When the gate 5 is closed, the interception net 6 intercepts large debris outside the gate 5, and collects smaller debris into the storage groove inside the interception net 6, preventing small debris from accumulating and forming a large debris pile. By intercepting debris outside the gate 5, these debris can prevent damage or blockage to downstream water conservancy facilities, river channels, water pumps, etc. When the debris accumulates to a certain level, the handle 9 can be pulled to drive the rotating column 7 outward, thereby driving the locking column 10 outward and separating from the outside of the gate 5, that is, contacting the rotation lock of the rotating column 7. Then, the rotating column 7 is rotated again, causing the locking block 8 to separate from the interception net 6, allowing the interception net 6 to be removed, thereby facilitating the timely cleaning of the debris.

[0037] When the gate 5 is closed, the water flowing from upstream will generate a certain impact force on the gate 5. At this time, the gate 5 and the gantry 1 are under force. Since the bottom of the ground nail 17 is inserted into the ground, the stability of the base 11 is guaranteed, which in turn makes the gate 5 and the gantry 1 tend to tilt backward, so that the connecting plate 2 15 converts the backward tilting trend into oblique pressure and transmits it to the transmission column 14, so that the transmission column 14 has a tendency to slide downward in the sleeve 13, so that the spring 16 has a certain compression trend, and the deformation of the spring 16 slows down the trend, and at the same time, this slowed trend is transmitted to the base 11 through the connecting plate 12, so that the backward tilting trend is offset again by the stability of the ground nail 17, thereby ensuring the stability of the entire gate 5.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
