Description

Technical Field

[0001] The present invention relates to the technical field of reservoir gate structures, in particular to a dual-mode water level regulating gate assembly. Background Art

[0002] Water conservancy projects are a dual-mode water level control system that uses various facilities to control, regulate, and utilize surface and groundwater, aiming to achieve multiple benefits such as flood control, irrigation, and water supply. These projects typically involve building dams to collect water and maintain high water levels within reservoirs for centralized scheduling and utilization. Gates, a key component in controlling water levels, control the amount of water released by adjusting their opening and closing states. Traditionally, gates are opened by vertical lifting. This method creates significant water pressure on one side of the gate when it is below the water level, while the other side is typically exposed to the air. This asymmetric pressure distribution causes the gate to exert a greater force on the non-water side of the dam, making it more difficult for the lifting mechanism to open the gate.

[0003] Furthermore, as the gate depth increases and its contact area with the reservoir expands, the hydrostatic pressure on the gate bottom also increases, further increasing the force required to open the gate. To address this issue, traditional lifting methods often rely on strengthening the gate's structure. However, this not only increases the gate's design and manufacturing costs, but also brings inconvenience to its operation, especially during frequent opening and closing.

[0004] Therefore, there is room for improvement in the existing technology to reduce operational difficulty and improve overall efficiency.

[0005] In view of this, the inventor specially designed a dual-mode water level control gate assembly, which resulted in this case. Summary of the Invention

[0040] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0041] The gate assembly, the foundation of the present invention, is typically located between the reservoir outlet and the downstream river channel. The gate plate 30 and hoist 41 control the opening of the gate plate 30, thereby clearing the flow passage 11 where the gate plate 30 is located and regulating the reservoir water volume. The gate assembly in this solution is explained below.

[0042] See also Figures 1 to 9 , is a dual-mode water level control gate assembly as the best embodiment of the present invention, comprising:

[0043] The gate base 10 is waist-shaped as a whole and is provided in multiple pieces and spaced apart between the revetments on both sides of the reservoir. The revetments on both sides are also counted as a gate base 10 to achieve connection. A flow channel 11 is formed between adjacent gate bases 10. Sealing channels 12 are symmetrically provided on both sides of the flow channel 11 and on opposite sides of adjacent gate bases 10. The upper ends of the sealing channels 12 pass through the gate base 10.

[0044] The support frame 20 is arranged between the revetments on both sides of the reservoir and is located directly above the gate base 10. In this embodiment, the upper end of the gate base 10 is integrally cast to form a support foundation 21. The support frame 20 is arranged on the upper end of the support foundation 21 and serves as the installation foundation for the hoist 41.

[0045] The gate plate 30 is vertically movable and penetrates between adjacent gate bases 10 and has vertical clearances on both sides with the sealing channel 12 to control the opening and closing state of the flow channel 11;

[0046] In this embodiment, both sides of the gate plate 30 are flat and are respectively inserted into the sealing channels 12 on both sides of the flow channel 11. Under the guiding action of the sealing channels 12, the up and down movement of the gate plate 30 is guided, and at the same time, a seal is formed on both sides of the gate plate 30 to maintain the overall airtightness between the gate plate 30 and the flow channel 11.

[0047] In order to further enhance the sealing performance, a sealing groove (not shown in the figure) may be provided at the bottom of the flow channel 11 to match the gap with the bottom of the gate plate 30 . The depth is set according to actual needs and is not limited here.

[0048] The opening and closing device 40 is provided on the support frame 20 and is used to drive the gate plate 30 to rise and fall to open or close the flow channel 11;

[0049] In this embodiment, the opening and closing device 40 includes a door opening machine 41 and a lifting screw 42 that is transmission-connected to the door opening machine 41. The lower end of the lifting screw 42 is hinged to the upper end of the gate plate 30 through a connecting ear (not marked in the figure), so that the gate plate 30 can be vertically lifted and lowered by the door opening machine 41 to realize the opening and closing of the flow channel 11.

[0050] The first pressure measuring device 50 is located on the pressure side of the gate plate 30 close to the upstream of the water flow and is located at several monitoring points at different heights formed on the pressure side, and is used to monitor the water pressure at the corresponding heights;

[0051] In this embodiment, the first pressure measuring device 50 is a water pressure sensor. A plurality of pressure measuring grooves 13 are provided on the side wall of the gate base 10 and on the pressure side of the gate plate 30. The pressure measuring grooves 13 are formed by the inward depression of the side wall of the gate base 10, so that the water flow on the pressure side of the gate plate 30 can be directly introduced, thereby facilitating the monitoring of the water pressure at the corresponding height position.

[0052] The compensation device 60 is provided with multiple groups and is located on the non-pressure side of each sealed channel 12 close to the downstream of the water flow. It includes a plurality of compensation units 61 and an energy supply unit 62 corresponding to the monitoring points at different heights. The compensation unit 61 has a retractable output end, and the energy supply unit 62 is used to provide retractable power to the output end of the compensation unit 61;

[0053] The second pressure measuring device 70 is provided to monitor the output pressure of the output end at different compensation points.

[0054] The second pressure measuring device 70 is a pressure sensor, which is arranged in contact with the output end of the compensation unit 61 and is used to monitor the output pressure of the output end, thereby realizing monitoring and correction of the compensation pressure of the compensation device 60.

[0055] Preferably, the compensation device 60 is an oil pressure compensation mechanism, the compensation unit 61 is an oil pressure mechanism, the oil pressure mechanism includes a shell 63, an output shaft 64, an output seat 65 and a pressure seat 66, the energy supply unit 62 is an oil pump station, the two sides of the shell 63 are divided into a front chamber 631 and a rear chamber 632 which are independent of each other, the front chamber 631 opens toward the sealing channel 12, the front chamber 631 and the rear chamber 632 are connected by an axial hole (not marked in the figure), the output seat 65 is clearance-fitted with the front chamber 631, the pressure seat 66 is clearance-fitted with the rear chamber 632, and the output seat 65 and the pressure seat 66 are fixedly connected by the output shaft 64 passing through both sides of the axial hole, the pressure seat 66 forms an oil pressure chamber (not marked in the figure) for accommodating pressurized oil on the side of the rear chamber 632 away from the front chamber 631, and the oil pressure chamber is connected to the oil pump station (not marked in the figure) through an oil delivery pipe and an oil return pipe.

[0056] In this embodiment, Figure 7 As shown, the shell 63 is a regular hexagon, and the front chamber 631 and the rear chamber 632 inside it are both chambers with regular hexagonal cross-sections. The output seat 65 and the pressure seat 66 are adapted to the shapes of the front chamber 631 and the rear chamber 632, so that the extension and retraction of the output seat 65 and the pressure seat 66 can be guided, so that a stable extension and retraction guiding process can be achieved.

[0057] Preferably, Figure 4 As shown, a spherical pressure-guiding portion 67 is movably provided in the front chamber 631 and on the side of the output seat 65 close to the sealing channel 12. The output seat 65 is provided with an embedding groove 651 adapted to the shape of the pressure-guiding portion 67. The spherical pressure-guiding portion 67 contacts the gate plate 30, which can further reduce the friction between the gate plate 30 and the compensation unit 61 during the opening process, thereby reducing the wear of the compensation unit 61 and extending the overall service life of the equipment.

[0058] Preferably, Figure 4As shown, a closing cover 633 is provided on the open side of the front chamber 631 , and a limiting hole 634 is provided through the middle of the closing cover 633 , the diameter of which is smaller than that of the pressure guiding portion 67 and allows the pressure guiding portion 67 to partially protrude from the front chamber 631 .

[0059] Thus, the limiting hole 634 can form a limit for the pressure guiding portion 67 , so that it can move stably in the front chamber 631 .

[0060] Preferably, Figure 5 、 6 As shown, pressure-guiding grooves 31 are vertically distributed and inwardly recessed on both sides of the gate plate 30 and on the non-pressure side close to the downstream of the water flow. The cross-section of the pressure-guiding grooves 31 is an arc shape that is adapted to the portion of the pressure-guiding portion 67 protruding from the front chamber 631.

[0061] Therefore, by opening a pressure-guiding groove 31 on the gate plate 30 that is adapted to the spherical surface of the pressure-guiding portion 67, on the one hand, it can serve as an exhaust channel when the output seat 65 is extended, so that the output seat 65 can be extended smoothly. On the other hand, it can also be guided during the vertical lifting process of the gate plate 30, so that the supporting force of the compensation unit 61 on the gate plate 30 always remains stable.

[0062] Preferably, Figure 8 As shown, the pressure-guiding portion 67 includes a spherical main body 671 and a plurality of replacement parts 672. The main body 671 is provided with a plurality of mounting grooves (not shown) radially therethrough. The mounting grooves are engaged with the replacement parts 672 and are locked and fixed by locking bolts 673. The outer side of the replacement part 672 forms an arc surface adapted to the main body 671 so that the main body 671 as a whole forms a complete sphere.

[0063] Therefore, because the pressure guide 67 is often exposed to high pressure and in frequent motion, it can wear out over time. By designing the pressure guide 67 as a combination of a main body 671 and a replacement part 672, if a particular part becomes severely worn, the corresponding replacement part 672 can be directly replaced without replacing the entire pressure guide 67, thereby reducing maintenance costs and downtime. Furthermore, because worn or damaged parts can be easily replaced, the overall service life of the pressure guide 67 is extended. This not only helps save costs but also ensures long-term stable operation of the system.

[0064] Preferably, Figure 7 As shown, a plurality of compensation units 61 are distributed in an array along the inner wall of the sealing channel 12, and the compensation units 61 between adjacent rows are staggered.

[0065] In this embodiment, three compensation units 61 are vertically spaced apart in the center, while two are located on each side. The compensation units 61 are spaced apart from the compensation units 61 on either side. Consequently, the array of compensation units 61 distributed along the inner wall of the sealing channel 12 forms a continuous pressure-supporting surface on the non-pressure side of the gate plate 30. This arrangement ensures more uniform pressure compensation on the non-pressure side of the gate plate 30 during opening or closing, thereby reducing local stress concentration and preventing deformation or damage to the gate plate 30. Furthermore, the staggered arrangement ensures that sufficient compensation units 61 are available throughout the height of the gate plate 30 for pressure compensation. Even if some compensation units 61 fail, others can continue to function, ensuring system redundancy and reliability. Specifically, since the compensation units 61 are not perfectly aligned but staggered, each compensation unit 61 is not in constant contact with the gate plate 30. This reduces the frequency of friction between the compensation units 61 and the gate plate 30, thereby reducing wear and extending the service life of the compensation units 61.

[0066] Preferably, Figure 4 As shown, an installation cavity 14 is provided on the inner side of the gate base 10. The oil pump station is arranged in the installation cavity 14 and includes a pump station box, a power pump and control valves (not marked in the figure) respectively arranged on the oil delivery pipe and the return oil pipe. The power pump is used to draw the pressure oil in the pump station box into the oil delivery pipe. The return oil pipe returns the oil to the pump station box under the natural pressure of the pressure seat 66. The control valve controls the conduction state of the oil delivery pipe and the return oil pipe, thereby forming a circulation path for the pressure oil, ensuring that the pressure oil can cooperate with the compensation unit 61 to achieve stable pressure output.

[0067] In this embodiment, in order to achieve stable sliding of the output seat 65 and the pressure seat 66, there is an air-guiding gap (not marked in the figure) between the shaft hole and the output shaft 64. The above scheme does not require vacuum treatment. On this basis, the space gap between the output seat 65 and the pressure seat 66 can also be vacuumed, and there is no restriction here.

[0068] Preferably, Figure 9 As shown, the system further includes a control module 80 , the first pressure measuring device 50 and the second pressure measuring device 70 are electrically connected to the input end of the control module 80 , and the compensation device 60 is electrically connected to the output end of the control module 80 .

[0069] In this embodiment, the control module 80 is a PLC control board, the first pressure measuring device 50 and the second pressure measuring device 70 are electrically connected to the input end of the PLC control board, the control valve and the power pump on the compensation device 60 are electrically connected to the output end of the PLC control board, the first pressure measuring device 50 at different positions measures the water pressure of the corresponding water depth, and after inputting the water pressure into the PLC control board, it is compared with the pressure value input by the second pressure measuring device 70 at the same height position. Then the PLC control board outputs a control signal to make the power pump and the control valve of the oil pipeline work, pushing the pressure seat 66 to move toward the gate plate 30, thereby making the pressure guiding part 67 contact the pressure guiding groove 31 on the gate plate 30, and multiple pressure guiding parts 67 simultaneously support the pressure guiding groove 31 at the corresponding position, so that the non-pressure side of the gate plate 30 is stably supported, its pressure is compensated, and the pressure on both sides of the gate plate 30 is balanced, which finally facilitates the opening and closing machine 41 to lift and lower the gate plate 30.

[0070] Thus, the solution of this embodiment can realize the first control mode of normally opening the gate plate 30 through the gate opening machine 41 under the condition of low water level and small pressure difference on both sides of the gate plate 30, and the second control mode of facilitating the opening of the gate plate 30 by compensating for the pressure difference under the condition of high water level and large pressure difference on both sides of the gate plate 30.

[0071] The beneficial effects of the present invention are as follows:

[0072] The present invention monitors the water pressure at different depths on both sides of the gate plate 30 by respectively arranging a first side pressure measuring device and a second pressure measuring device 70 at different depths on the pressure side and the non-pressure side of the gate plate 30, thereby compensating for the pressure on the pressure side of the gate plate 30 on the non-pressure side of the gate plate 30, reducing the power consumption required by the opening and closing device 40 to open the gate plate 30, and to a certain extent, also reducing the requirements for the structural strength of the gate plate 30, so that the gate plate 30 can be opened and closed in a more energy-saving and cost-effective manner.

[0073] In addition, the spherical pressure-guiding portion 67 contacts the gate plate 30 , which can further reduce the friction between the gate plate 30 and the compensation unit 61 during the opening process, thereby reducing the wear of the compensation unit 61 and extending the service life of the entire equipment.

[0074] In addition, by opening a pressure-guiding groove 31 on the gate plate 30 that is adapted to the spherical surface of the pressure-guiding portion 67, on the one hand, it can serve as an exhaust channel when the output seat 65 is extended, allowing the output seat 65 to be extended smoothly. On the other hand, it can also provide guidance during the vertical lifting process of the gate plate 30, so that the supporting force of the compensation unit 61 on the gate plate 30 always remains stable.

[0075] Pressure monitoring and compensation: The first and second pressure measuring devices 50 and 70 monitor the water pressure changes at different heights upstream and downstream in real time, and the compensation device 60 balances these pressure differences. This effectively reduces the resistance when the gate is opened and reduces operating costs.

[0076] Specifically, the compensation unit 61 utilizes a hydraulic mechanism. Powered by an oil pump station, the output shaft 64 of the compensation unit 61 can be extended and retracted as needed, thereby offsetting the water pressure acting on the gate. The pressure-guiding portion 67 is spherical, reducing friction with the gate plate 30. The presence of the pressure-guiding groove 31 also facilitates air venting and guidance.

[0077] In addition, the entire system is coordinated by a control module 80, which receives data from the pressure measuring device and controls the working state of the compensation device 60 to achieve automated operation, thereby improving the response speed and accuracy of the system.

[0078] In addition, the low-friction design reduces wear between mechanical components, and the reasonable structural layout makes the entire assembly more durable and has lower maintenance costs.

[0079] In addition, by reducing energy consumption during operation, the design is also more in line with the trend of modern water conservancy projects pursuing environmental protection and energy conservation.

[0080] In summary, this dual-mode water level control gate assembly not only improves work efficiency but also reduces maintenance costs.

[0081] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
