Description

Technical Field

[0001] This invention relates to a right-angle ring-type fully automatic stepless layered water intake stacked beam gate device and its control method, belonging to the field of hydropower station ecological and environmental protection technology. Background Technology

[0002] Hydropower, as a clean and environmentally friendly energy source, occupies an important position in my country's energy structure, leading to the construction of numerous large-scale hydropower projects utilizing this energy form. However, the construction of hydropower dams alters the hydrological conditions of natural rivers, resulting in significant differences in water temperature between upstream and downstream areas. This disrupts the aquatic environment upon which aquatic organisms depend for survival and adversely affects the ecological balance of the basin.

[0003] To change the current situation, stratified water intake technology, through precise control of the water intake elevation, can effectively regulate the temperature of the discharged water, making it more suitable for the survival needs of aquatic organisms, and has become a key technical means for the ecological and environmental protection transformation of hydropower projects. In existing stratified water intake technologies, traditional flat-plate stacked beam gates need to be stacked in the gate slots, and surface water intake can only be achieved by adding, removing, or moving the top stacked beam gate. This makes it impossible to flexibly adjust the water intake elevation according to the water temperature distribution, making it difficult to achieve the ideal water temperature control effect. Furthermore, its operation process is complex, requiring multiple technicians to coordinate the operation of the gate system to open and close the gates layer by layer, which is time-consuming, labor-intensive, and inefficient. While flap-type and louver-type stacked beam gates, which have not been put into practical use, attempt to optimize water intake regulation, their complex structural design and the fact that the oil and electricity systems are located underwater pose significant safety risks such as electrical and oil leaks in reservoirs tens of meters deep, making reliability and safety difficult to guarantee.

[0004] Application CN114922142A discloses a tiered water intake device and method with in-slot lifting and folding mechanism. The device includes a stacked beam gate slot and a stacked beam gate. An opening and closing equipment platform is located above the stacked beam gate slot, and opening and closing equipment is mounted on the platform. The stacked beam gate is located within the stacked beam gate slot, and its top is connected to the opening and closing equipment, which controls the gate's lifting and lowering along the slot. The device raises the water-blocking height under the lifting action of the opening and closing equipment and lowers the water-blocking height under the weight of the gate leaf, thus achieving surface water intake. A close examination of this technology reveals that its water intake regulation relies on the overall lifting and folding of the gate, which can only achieve rough control of surface water intake and cannot achieve full-range, high-precision stepless water intake regulation based on the water temperature gradient at different water depths. Secondly, it relies on its own weight to fall and cannot descend freely under the action of the water pressure difference between the upstream and downstream. Finally, its control system is mainly based on the upstream and downstream water level difference signal for regulation, and does not fully integrate water temperature distribution data for intelligent linkage, resulting in insufficient targeting and precision of water temperature regulation.

[0005] In summary, existing stratified water intake devices still have room for improvement in terms of water intake regulation accuracy, water temperature control targeting, and structural reliability. There is an urgent need to develop a stratified water intake device that can achieve fully automatic stepless precise water intake, intelligent control combined with water temperature signals, and stable and reliable structure, so as to meet the dual requirements of ecological and environmental protection and efficient operation of hydropower projects. Summary of the Invention

[0006] This invention provides a right-angle ring-type fully automatic stepless layered water intake stacked beam gate device and its control method, which can achieve stepless and precise water intake by combining water temperature and pressure, so as to meet the synergistic consideration of ecological environmental protection and power generation benefits.

[0007] The technical solution adopted by this invention to solve its technical problem is: A right-angle ring-type fully automatic stepless layered water intake stacked beam gate device, wherein a stacked beam gate slot is opened in the part of the concrete pier of the hydropower station's power generation intake facing the water flow in. Define the bottom of the stacked beam gate slot as the origin, the direction perpendicular to the water surface as the Y-axis, and the direction parallel to the water surface as the X-axis to establish a two-dimensional coordinate system; A drive wheel is installed above the top of the stacked beam slot in the Y-axis direction, a large steering wheel is installed at the origin, and a small steering wheel is installed in the X-axis direction opposite to the large steering wheel. At the same time, the large steering wheel, the drive wheel, and the small steering wheel form an isosceles right triangle with the large steering wheel as the vertex. The transmission steel wire rope is sequentially arranged with a large steering wheel, a drive wheel, and a small steering wheel, and also includes several stacked beam door panels. Adjacent stacked beam door panels are connected by a flexible structure to form a stacked beam door assembly. The two ends of the stacked beam door assembly are fixed to the transmission steel wire rope. Under the rotation of the drive wheel, the transmission steel wire rope carries the stacked beam door assembly to slide up and down in the Y-axis direction within the stacked beam door groove. Furthermore, the drive wheel is mounted on the concrete pier at the hydropower station's water intake. Furthermore, the stacked beam door panel is made of hollow steel plate, and pulleys are installed on the side of each stacked beam door panel that contacts the stacked beam door groove, and sliding grooves are installed on the side wall of the stacked beam door groove that contacts the stacked beam door panel, with the pulleys and sliding grooves matching each other; Furthermore, adjacent stacked beam door panels are connected by a flexible densely woven steel wire mesh, and rubber is injected into the flexible densely woven steel wire mesh; and the shear strength of the flexible densely woven steel wire mesh is ≥200N; Furthermore, a control room is set up at the concrete pier of the hydropower station's power generation intake where the drive wheel is installed. The control room is equipped with a central control system and a motor. The central control system is electrically connected to the motor. The drive wheel is mounted on the motor shaft. When the motor is started, the drive wheel rotates to adjust the opening of the stacked beam gate assembly. Furthermore, temperature sensors and pressure sensors are installed on the plate surfaces of each stacked beam gate assembly facing the upstream and downstream water flows, and a water level sensor is also installed on the plate surface facing the upstream water flow. The control method for the right-angle ring type fully automatic stepless layered water intake stacked beam gate device includes the following steps: Step S1: The central control system reads the signals from the upstream and downstream temperature sensors and the upstream water level sensor to obtain water temperature information at different water depths upstream and downstream, as well as upstream water level information. Step S2: Based on the water temperature information, adjust the position of the stacked beam gate assembly within the stacked beam gate slot. If the water temperature information shows a distribution of high surface water temperature and low deep water temperature in the reservoir, the central control system sends a start signal to the drive wheel. The drive wheel rotates, and the large and small steering wheels drive the stacked beam gate assembly to slide upwards on the Y-axis. At this time, the hydropower station generator unit draws water from the high-temperature surface layer of the reservoir. If the water temperature information shows a distribution of low surface water temperature and high deep water temperature in the reservoir, the drive wheel rotates in the opposite direction, and the large and small steering wheels drive the stacked beam gate assembly to slide downwards on the Y-axis. At this time, the hydropower station generator unit draws water from the low-temperature deep layer of the reservoir. Furthermore, when the drive wheel drives the stacked beam door panel assembly to slide upwards on the Y-axis, the winding speed of the stacked beam door assembly is set to... ,but ,in, Motor power, The thrust or pull applied to the drive wheel, , n , , The coefficient of friction between the stacked beam door panel and the stacked beam door groove.

The height of the stacked beam door panels is the distance along the Y-axis. To ensure the water-blocking function, the number of layers of the stacked beam door panels can be closed. For the quality of the stacked beam door panels, It is the acceleration due to gravity. , This refers to the total mass of the transmission wire rope. The mass of the transmission wire rope located on the X-axis; Furthermore, when the drive wheel drives the stacked beam door panel assembly to slide upwards on the Y-axis, the winding speed of the stacked beam door assembly is set to... ,but ,in, For motor power, The thrust or pull applied to the drive wheel, , n , , The coefficient of friction between the stacked beam door panel and the stacked beam door groove.

[0008] By employing the above technical solutions, the present invention has the following beneficial effects compared to the prior art: 1. The right-angle ring type fully automatic stepless layered water intake stacked beam gate device provided by the present invention maintains the flat plate structure characteristics of the stacked beam gate group. While realizing stepless layered water intake, it does not increase the resistance of water flow, effectively controls the head loss, and ensures the power generation efficiency of the hydropower station. 2.

Detailed Implementation

[0012] The present invention will now be described in further detail with reference to the accompanying drawings. In the description of this application, it should be understood that the terms "left side," "right side," "upper part," "lower part," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. "First," "second," etc., do not indicate the importance of the components, and therefore should not be construed as a limitation of the present invention. The specific dimensions used in this embodiment are only for illustrating the technical solution and do not limit the scope of protection of the present invention.

[0013] The background section details existing technologies for using stacked beam gates to achieve stratified water intake. This primarily involves the combination of folding stacked beam gates and winch-type hoists to achieve in-slot lifting and surface water intake, simplifying the operation process and saving gate space to some extent. However, the biggest problem with this design in practical application is that the stacked beam gate relies on its own weight to fall, and cannot descend freely under the pressure difference between the front and rear water sections.

[0014] Therefore, the main innovative design highlight of the right-angle ring-type fully automatic stepless layered water intake stacked beam gate device provided in this application is its ability to achieve both clockwise and counterclockwise rotation of the stacked beam gate, that is, it can be achieved by applying power during either clockwise or counterclockwise operation. One advantage of this design is that it does not modify the existing gate slot structure of the hydropower station, but directly utilizes the existing stacked beam gate slot for installation, reducing modification costs and construction difficulty. The overall structure is as follows: Figures 3-4 As shown, a stacked beam slot 6 is opened in the part of the concrete pier 1 at the water inlet of the hydropower station facing the water flow. For ease of description, the bottom of the stacked beam slot is defined as the origin, the direction perpendicular to the water surface is the Y-axis, and the direction parallel to the water surface is the X-axis, thus establishing a two-dimensional coordinate system.

[0015] The entire design uses a transmission steel wire rope 5 to adjust the opening of the stacked beam door. In actual operation, the pulling force required to lift the door needs to be considered. To reduce wear on the transmission steel wire rope and facilitate lifting, a drive wheel 9 is installed above the top of the door slot along the Y-axis, a large steering wheel 3 is installed at the origin, and a small steering wheel 4 is installed opposite the large steering wheel along the X-axis. The transmission steel wire rope is sequentially arranged around the large steering wheel, drive wheel, and small steering wheel. When the viewpoint of the stacked beam door on the Y-axis moves upwards in the diagram, the transmission steel wire rope moves downwards. The inclined transmission steel wire rope reduces the power required, fully utilizing the gravitational potential energy of the transmission steel wire rope and reducing the pulling force required to lift the door upwards. Of course, since it is necessary to ensure the stacked beam door can be fully closed in the Y-axis direction (…),… Figure 1 (as shown) and all open ( Figure 2 As shown in the figure, in this application, the large steering wheel, the drive wheel, and the small steering wheel form an isosceles right triangle with the large steering wheel as the vertex.

[0016] Several stacked beam gate panels are connected sequentially to form a stacked beam gate assembly. Both ends of the assembly are fixed to a drive steel wire rope. Driven by the rotation of the drive wheel, the steel wire rope propels the stacked beam gate assembly up and down in the Y-axis direction within the gate slot. As clearly shown in the diagram, the stacked beam gate assembly still operates in a retractable manner. This design eliminates the need to lift the entire assembly to the gate chamber at the top of the dam, enabling stepless water intake. Compared to the traditional method of hoisting and installing stacked beam gates piece by piece, this significantly reduces operation time. Furthermore, the gate assembly occupies less space during retraction, making it suitable for space-constrained hydropower station renovation projects.

[0017] In this application, the stacked beam gate assembly is formed by connecting several stacked beam gate panels. As an advantage, the stacked beam gate panels maintain a similar external dimensions to traditional stacked beam gates, ensuring geometric compatibility with the original gate slots. Since the stacked beam gate assembly maintains a flat shape and has no additional protrusions or flow guiding structures, the water flow remains streamlined when passing through the stacked beam gate assembly, and the head loss is comparable to that of traditional flat gates, without affecting the power generation efficiency.

[0018] In the embodiments provided in this application, adjacent stacked beam door panels are connected by a flexible structure. This flexible connection allows the stacked beam door assembly to bend at the steering wheels while maintaining overall strength. Preferably, adjacent stacked beam door panels are connected by a flexible densely woven steel wire mesh with a shear strength ≥200N. Since the stacked beam door assembly needs to achieve a water-blocking effect, rubber is injected into the flexible densely woven steel wire mesh, balancing structural strength and sealing performance, and further resisting water flow impact and silt abrasion, significantly improving structural stability and durability.

[0019] To further reduce energy consumption and extend service life, the stacked beam door panels are made of hollow steel plates, which are strong enough to effectively block water. Pulleys are installed on the sides of each stacked beam door panel that contact the door groove, and sliding grooves are installed on the sidewalls of the door groove that contact the door panel. The pulleys and grooves are matched to reduce the sliding resistance of the stacked beam door panels within the door groove.

[0020] The entire device is designed to operate automatically through a central control system. In this application, the drive wheel is installed on the concrete pier of the hydropower station's water intake. A control room is set up at the location of the concrete pier where the drive wheel is installed. The central control system and motor are installed in the control room. The central control system is electrically connected to the motor. The drive wheel is mounted on the motor shaft. When the motor is started, the drive wheel rotates to adjust the opening of the stacked beam gate assembly. Figure 5 and Figure 6 This is an enlarged schematic diagram of the positions of the small steering wheel and the drive wheel.

[0021] In actual operation, the right-angle ring-type fully automatic stepless tiered water intake stacked beam gate device must fully consider the water flow pressure that the stacked beam gate assembly needs to face when opening. If the water pressure is too high, the motor power will be insufficient to provide enough pulling or pushing force. Therefore, this application also provides a control method for the right-angle ring-type fully automatic stepless tiered water intake stacked beam gate device. The principle is that the central control system dynamically adjusts the winding speed according to the pressure difference to avoid jamming or structural damage caused by water pressure imbalance. Since the control method involves water temperature, water level, and pressure parameters, temperature sensors 7 and pressure sensors are installed on the plates facing the upstream and downstream water flows of each stacked beam gate assembly. At the same time, a water level sensor 8 is also installed on the plate facing the upstream water flow. Of course, the downstream temperature sensor is actually installed at the outlet of the tail water pipe. When the temperature at the outlet of the tail water pipe is detected to be lower than the set temperature, the opening of the stacked beam gate needs to be adjusted to obtain a higher water temperature.

[0022] Figure 7 As shown, the control method includes the following steps: Step S1: The central control system reads the signals from the upstream and downstream temperature sensors and the upstream water level sensor to obtain water temperature information at different water depths upstream and downstream, as well as upstream water level information. Step S2: Based on the water temperature information, adjust the position of the stacked beam gate assembly within the stacked beam gate slot. If the water temperature information shows a distribution of high surface water temperature and low deep water temperature in the reservoir, the central control system sends a start signal to the drive wheel. The drive wheel rotates, and the large and small steering wheels drive the stacked beam gate assembly 2 to slide upwards on the Y-axis. At this time, the hydropower station generator unit draws water from the high-temperature surface layer of the reservoir. If the water temperature information shows a distribution of low surface water temperature and high deep water temperature in the reservoir, the drive wheel rotates in the opposite direction, and the large and small steering wheels drive the stacked beam gate assembly to slide downwards on the Y-axis. At this time, the hydropower station generator unit draws water from the low-temperature deep layer of the reservoir.

[0023] When controlling the device, the winding speed is related to the pressure and the winding area according to actual needs. Since the pressure experienced by the stacked beam door assembly differs when it is opened and closed, the winding speed of the stacked beam door assembly is set as follows when the steering wheel drives the stacked beam door panel 2 to slide upwards on the Y-axis: ,but ,in, For motor power, The thrust or pull applied to the drive wheel, , n , , The coefficient of friction between the stacked beam door panel and the stacked beam door groove. To withstand the pressure of the upstream water flow directly facing the stacked beam gate assembly, To reduce the pressure of the downstream water flow directly facing the stacked beam gate assembly, The width of the stacked beam door panel. The height of the stacked beam door panels is the distance along the Y-axis. To ensure the water-blocking function, the number of layers of the stacked beam door panels can be closed. For the quality of the stacked beam door panels, It is the acceleration due to gravity. , This refers to the total mass of the transmission wire rope. The mass of the transmission wire rope located on the X-axis.

[0024] When the steering wheel drives the stacked beam door panel assembly to slide upwards on the Y-axis, the winding speed of the stacked beam door assembly is set to... ,but ,in, For motor power, The thrust or pull applied to the drive wheel, , n , , The coefficient of friction between the stacked beam door panel and the stacked beam door groove.

For the quality of the stacked beam door panels, It is the acceleration due to gravity. , This refers to the total mass of the transmission wire rope. The mass of the transmission wire rope located on the X-axis.

[0025] In summary, the right-angle ring-type fully automatic stepless layered water intake stacked beam gate device and its control method provided in this application, through innovative roller shutter-type structural design and intelligent control system, combined with real-time monitoring of upstream and downstream water temperatures and water depths by water temperature sensors, can accurately select water intake layers that meet ecological requirements. This effectively solves the problems of insufficient water intake regulation precision and poor water temperature control specificity in existing devices, making the downstream discharged water temperature more suitable for the survival needs of aquatic organisms and significantly improving the ecological and environmental benefits of hydropower projects. The gate opening can be automatically adjusted based on water temperature and water level data without manual intervention, and there is no need to raise the gate leaf to the top of the dam gate chamber, greatly shortening the gate action time and significantly improving operational efficiency. At the same time, it supports remote operation and unattended operation, reducing labor costs and aligning with the development trend of automation and intelligence in modern hydropower projects.
