Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy gates, in particular to a regulating gate with a gate flushing and silting structure for water conservancy projects. Background Art

[0002] In water conservancy projects, the control gate is an important facility for regulating water flow, water level and water volume. The optimization of its structure and function directly affects the efficiency of water body management and protection. The traditional control gate is mainly composed of a gate seat, a gate plate and a lifting mechanism, which is used to control the passage and blocking of water flow. However, due to the presence of suspended matter and sediments in the water body, after long-term operation, the gate plate of the control gate is prone to silt deposition and impurities adhesion, which not only affects the lifting function of the gate plate, but also greatly reduces the circulation efficiency of the water flow.

[0003] In existing control gate applications, most designs are not equipped with effective silt flushing structures. Due to the lack of a dedicated flushing mechanism, silt and impurities often accumulate on the gate surface, which not only increases the burden on the gate, but may also cause deformation or damage to the gate, affecting its long-term stable operation. In addition, the accumulation of silt may also cause water flow obstruction, increase the water level upstream, and cause water overflow or other safety issues.

[0004] For some control gate designs that have tried to integrate flushing and silting functions, the results are often unsatisfactory. In these designs, the flushing and silting structure is usually unable to flush the gate plate in an all-round and uniform manner, resulting in the existence of flushing dead corners, which makes it difficult to remove silt in some areas. In the long-term operation process, these areas that have not been flushed clean may cause structural damage or poor movement due to excessive silt.

[0005] In addition, the water filtration structure included in the design of the silt flushing system of some control gates is often easily blocked by silt during the water extraction and discharge process due to unreasonable design or limited filtering capacity. This blockage not only affects the efficiency of silt flushing, but also increases maintenance costs and labor intensity. Once the filter screen or filter box fails due to silt blockage, the function of the entire silt flushing system will be greatly reduced, and the silt on the gate plate cannot be effectively removed, which in turn affects the normal operation of the control gate and the flow efficiency of the water flow.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] See also Figure 1-8 A regulating gate with a gate scouring and silting structure for a water conservancy project comprises a gate seat 1, a gate plate 2, a lifting mechanism 3, and a scouring and silting assembly. A water flow opening is opened on the inner side of the gate seat 1, the gate plate 2 is assembled in the water flow opening and moves up and down in the vertical direction, and both sides of the gate plate 2 are evenly fixed with strengthening ribs 21 arranged in the vertical direction. The lifting mechanism 3 is assembled on the top of the gate seat 1 and maintains a power connection with the gate plate 2.

[0037] The silt flushing assembly includes a connecting seat 41, a water pump 42, and a water filter box 43. The connecting seat 41 is fixedly installed on the top of the gate plate 2, and the bottom of the connecting seat 41 is evenly equipped with silt flushing nozzles 411, which are arranged in the gaps between adjacent reinforcing ribs 21. The water filter box 43 is fixedly installed on the bottom of the upstream side of the gate seat 1, and the water filter box 43 is provided with an obliquely arranged water filter mesh plate 431. The water pump 42 is fixedly installed on the top of the gate seat 1, and the water inlet of the water pump 42 is connected to the water filter box 43 through a water supply hose 421, and the drain outlet of the water pump 42 is connected to the inner cavity of the connecting seat 41 through a drain hose 422.

[0038] The gate seat 1 is cast with reinforced concrete, which can ensure that the gate plate 2 and the lifting mechanism 3 are stably assembled thereon. The reinforced ribs 21 on both sides of the gate plate 2 are designed to enhance the structural strength of the gate plate 2, reduce the water flow resistance and increase the water-facing area of ​​the gate plate 2. The vertical bar-shaped protrusions can increase the rigidity and bending resistance of the gate plate 2, so that the gate plate 2 can better withstand the pressure and other mechanical loads from the water flow, which helps to prevent the gate plate 2 from deformation or damage during long-term use; the protrusion design can optimize the streamline of the water flow through the gate plate 2 to a certain extent, reduce the generation of eddy currents, thereby reducing the resistance and impact of the water flow on the gate plate 2, and the increased water-facing area can improve the contact surface between the gate plate 2 and the water to a certain extent, thereby increasing the risk of preventing freezing in winter.

[0039] The gate plate 2 can be driven to move up and down in the water flow opening by the lifting mechanism 3 to adjust the effective cross-sectional area of ​​the water flow opening, thereby realizing the regulation of the water flow rate and flow velocity.

[0040] The silt flushing assembly operates when the gate plate 2 is in the open position. Under the action of the water pump 42, the water on the upstream side of the regulating gate can intercept impurities and silt in the water under the filtering action of the water filter mesh plate 431, and the water entering the filter box 43 after filtration is transported to the inner cavity of the connecting seat 41 along the water supply hose 421 and the drainage hose 422, and then the two sides of the gate plate 2 are flushed from top to bottom through the silt flushing nozzle 411 opened at the bottom thereof to remove the silt attached to the surface of the gate plate 2, to ensure the cleanliness of the gate plate 2, to prevent the gate plate 2 from being eroded by silt for a long time and affecting its normal operation, and to prevent silt deposition from causing the gate plate 2 to be difficult to stably rise and fall in the water flow opening, to ensure the normal flow of water through the water flow opening.

[0041] The flushed silt can flow downstream along with the water flow. The water filter mesh plate 431 is arranged in an inclined shape. When the gate plate 2 is in an open position, the flowing water flow can flush the silt impurities intercepted on the water filter mesh plate 431, thereby ensuring the cleanliness and permeability of the water filter mesh plate 431 itself, so as to ensure that the silt flushing component can operate stably for a long time.

[0042] In order to ensure that the gate plate 2 can be stably raised and lowered in the vertical direction inside the water flow opening, the following technical solution is provided.

[0043] A guide groove 12 is fixedly connected to the inner wall of the water flow opening, and a guide rail 13 arranged along the vertical direction is fixedly installed in the guide groove 12; the gate plate 2 is nested and installed on the inner side of the guide groove 12, and a clearance groove 22 arranged along the vertical direction is opened on the gate plate 2, the guide rail 13 is arranged on the inner side of the clearance groove 22, and an assembly groove 23 is opened on the inner side of the clearance groove 22, and a support wheel 24 that maintains a matching combination with the guide rail 13 is rotatably installed in the assembly groove 23.

[0044] The setting of the guide groove 12 can effectively limit the gate plate 2, preventing the gate plate 2 from tipping over to the downstream side of the control gate due to the impact of the water flow, and the combination of the guide rail 13 and the support wheel 24 can effectively reduce the resistance of the gate plate 2 during the lifting and lowering movement, making it convenient to control the lifting and lowering movement of the gate plate 2. The setting of the clearance groove 22 can avoid spatial interference between the gate plate 2 and the guide rail 13.

[0045] In order to ensure that the silt flushing assembly can effectively flush the end surface of the gate plate 2 in the width direction and prevent silt deposition from affecting the normal lifting and lowering of the gate plate 2, the following technical solution is provided.

[0046] Both ends of the connection seat 41 are equipped with silt flushing nozzles 412 , and the silt flushing nozzles 412 are arranged in the clearance groove 22 .

[0047] The water flow in the inner cavity of the connecting seat 41 can be sprayed outward through the silt flushing nozzle 412 to effectively flush the inner wall of the clearance groove 22 and the guide rail 13 to prevent silt from adhering and depositing here and affecting the normal lifting and lowering of the valve plate.

[0048] In order to ensure that the lifting mechanism 3 can be stably installed on the top of the gate seat 1 and to ensure that the lifting mechanism 3 can drive the gate plate 2 to rise and fall stably, the following technical solution is provided.

[0049] An assembly bracket 14 is fixed on the top of the gate seat 1, and the lifting mechanism 3 includes a winding roller 31, a guide wheel 32, a steel rope 33, and a driving motor 34. The winding roller 31 includes two groups that are rotatably mounted on the assembly bracket 14 and maintained in a symmetrical arrangement, and a steel rope 33 is wound on the winding roller 31. The guide wheel 32 includes multiple groups that are rotatably mounted on the assembly bracket 14. The steel rope 33 is fixedly connected to the top of the gate plate 2 after passing through each group of guide wheels 32. The driving motor 34 is fixedly mounted on the assembly bracket 14 and maintains a power connection with the two groups of winding rollers 31.

[0050] The provision of the assembly bracket 14 can ensure that the components in the lifting mechanism 3 can be stably mounted thereon, and the water pump 42 is also mounted on the assembly bracket 14 .

[0051] When the driving motor 34 is working and drives the two sets of winding drums to operate, the matching steel rope 33 can be synchronously retracted and released, and then the steel rope 33 pulls the gate plate 2 up and down to achieve the regulation of water flow and flow rate. The two sets of winding rollers 31 are each designed with multiple sets of guide wheels 32 arranged in different directions to ensure that the steel rope 33 released by the winding roller 31 is finally connected to the top of the gate plate 2 in the vertical direction.

[0052] In order to ensure that the steel rope 33 can pass through the top of the gate seat 1 and realize its effective connection with the gate plate 2, a clearance opening 15 is also opened on the top of the gate seat 1 to facilitate the installation of the guide wheel 32 here, while ensuring that the steel rope 33 bypassing the guide wheel 32 can be fixedly connected to the lower gate plate 2.

[0053] Since the two groups of winding rollers 31 are arranged symmetrically, in order to ensure that the driving motor 34 can simultaneously drive the two groups of winding rollers 31 to operate at the same speed so as to synchronously retract and release the steel rope 33, the following technical solution is provided.

[0054] The lifting mechanism 3 also includes a worm wheel 311, a worm 351 and two groups of driving half shafts 35 symmetrically arranged on both sides of the driving motor 34. A driving bevel gear 341 is fixedly connected to the output shaft of the driving motor 34. The driving half shaft 35 is rotatably installed on the assembly bracket 14, and a transmission bevel gear 352 that meshes with the driving bevel gear 341 is fixedly connected to the driving half shaft 35. The worm wheel 311 is fixedly connected to the axis center of the winding roller 31, and the worm 351 is fixedly connected to the driving half shaft 35 and maintains a matching combination with the worm wheel 311.

[0055] When the driving motor 34 drives the driving bevel gear 341 to operate, it can operate through the transmission bevel gear 352 and the driving half shaft 35. Since the two sets of driving half shafts 35 and the transmission bevel gears 352 thereon are symmetrically distributed, the two sets of driving half shafts 35 can operate in the opposite direction at the same speed, and then the corresponding worm 351 is used to drive the worm wheel 311 and the winding drum to operate in the opposite direction, so as to realize the synchronous retraction and release of the steel rope 33 thereon.

[0056] At the same time, the combination of the worm wheel 311 and the worm 351 also has a self-locking effect, that is, the power at the worm wheel 311 end cannot be transmitted back to the worm 351. After the driving motor 34 drives the winding drum to operate through the combination of the worm 351 and the worm wheel 311 and adjusts the lifting posture of the gate plate 2, the lifting mechanism 3 is in a self-locking state and will not be affected by the gravity of the gate plate 2, causing the lifting mechanism 3 to reversely operate.

[0057] In order to facilitate the cleaning and flushing of the silt deposited on the upstream side of the gate seat 1 and the silt deposited near the water filter box 43 by means of water flow, the following technical solution is provided.

[0058] The bottom of the upstream side of the gate seat 1 is sequentially provided with a first step 16 and a second step 17 which rise gradually. The first step 16 is nested and matched with the bottom of the water-facing side of the gate plate 2. An installation trough 171 is opened at the center of the second step 17, and the water filter box 43 is fixedly installed in the installation trough 171.

[0059] The setting of the first step 16 and the second step 17 facilitates the rapid flushing of the silt deposited here due to the change in height when the water flows through this place. The first step 16 and the second step 17 are provided with an arc-shaped transition surface or an inclined transition surface on the side facing the downstream side, which can effectively prevent impurities and silt carried in the water flow from being deposited at the bottom of the steps.

[0060] When the gate 2 is in a fully closed state, the silt and impurities contained in the water will be deposited at the position of the first step 16 and the gate 2. When the gate 2 is opened, the deposited silt can be quickly flushed into the downstream side under the scouring effect of the water flow.

[0061] The setting of the secondary step 17 ensures the stability of the installation of the water filter box 43 here, and avoids the obstruction of the water filter box 43 causing the water flow to slow down here and cause silt and impurities to accumulate near the water filter box 43.

[0062] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0063] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
