Description

Technical Field

[0001] This invention relates to a fully automatic stratified water intake stacked beam gate system and a stratified water intake control method, belonging to the field of hydropower station ecological and environmental protection technology. Background Technology

[0002] Hydropower is a clean energy source, and my country has constructed numerous large-scale hydropower projects. The construction of hydropower dams causes water temperature stratification in the upstream reservoirs, and the hydropower station's water intake pipes are located at the bottom of the reservoir. This results in a significant temperature difference between the water flowing downstream during power generation and the downstream river channel temperature, which is detrimental to the survival of aquatic life in the downstream river. To change this situation, stratified water intake technology can control the water temperature flowing downstream by regulating the intake elevation, making the water temperature downstream of the hydropower station more suitable for aquatic life and providing technical support for ecological and environmental protection.

[0003] Existing stratified water intake technologies mainly include stacked beam gates, front retaining walls, multi-layer water intakes, water temperature control curtains, louvers, intake tower cylindrical gates, and inclined stratified water intakes. The stratified water intake technology already in practical use in power plants primarily employs flat-plate stacked beam gates. These gates are stacked within gate slots, allowing control of the surface water intake only by moving them out or adding the top layer of gates. This only controls the depth of the surface water and cannot regulate water temperature by drawing water from reservoirs at different elevations and temperatures. Furthermore, flat-plate stacked beam gate technology is complex, requiring multiple engineers to coordinate the gate operator system to open and close the gates layer by layer, and is time-consuming.

[0004] Existing invention patents have upgraded the stacked beam gate technology for stratified water intake, the most typical being the flap gate technology (application number 202210043984.6). Its principle is to create a door frame by opening a hole in the center of a flat stacked beam gate, and then add door leaves to control the opening and closing of the gate. This method can basically achieve fully automatic control of the stacked beam gate's opening and closing. However, the flap gate technology requires a series of complex technologies including electrical, mechanical, and hydraulic systems. After the flap gate is installed underwater in the upper reservoir, problems such as oil leakage and water ingress in the hydraulic system cannot be overcome, which actually increases the water pollution problem in the upstream reservoir. Moreover, after the flap gate is opened, it is equivalent to adding an obstacle in the flow channel, leading to increased head loss.

[0005] Therefore, it is necessary to design a new type of fully automatic layered water intake stacked beam gate system to solve the above problems. Summary of the Invention

[0006] This invention provides a fully automatic layered water intake stacked beam gate system and a layered water intake control method, which realizes fully automatic layered water intake at the power generation inlet, ensuring the safety and efficiency of the system.

[0007] The technical solution adopted by this invention to solve its technical problem is: A fully automatic layered water intake stacked beam gate system includes several stacked beam gate frames, several stacked beam gate leaves, and hook beams. In the vertical and horizontal direction, several stacked beam gate frames are sequentially stacked from top to bottom in the stacked beam gate slot inside the hydropower station's power generation water intake. Each stacked beam gate frame is embedded with stacked beam gate leaves to form a stacked beam group. When the stacked beam gate slot is full of stacked beam groups, the stacked beam gate closes to achieve the function of blocking water. In this configuration, several hanging beams are provided on the surface of each stacked beam door leaf, and several hanging beam supports are installed on the vertical sidewall of each stacked beam door frame. The number and position of the hanging beams and hanging beam supports are matched. When the stacked beam door leaf is embedded in the stacked beam door frame, the hanging beams are mounted on the hanging beam supports, and the hanging beams slide against the inner side of the hanging beam supports, while simultaneously driving the stacked beam door leaf to slide vertically downward until the surface of the stacked beam door leaf is tightly fitted with the stacked beam door frame. A hanging space is formed between several hanging beams set on the surface of the stacked beam door leaf. The shape of the hook beam matches the hanging space. When the hook beam is embedded in the set hanging space of the stacked beam door leaf, the hook beam is lifted to lift the stacked beam door leaf and open the stacked beam door to realize the water intake function. Furthermore, the stacked beam door frame has a U-shaped structure with a square through-hole at its center and a frame around the through-hole. The direction of water inflow is defined as the upstream of the stacked beam door frame, and the direction of water outflow is the downstream of the stacked beam door frame. Protruding vertical frames are set on both sides of the vertical horizontal plane upstream of the stacked beam door frame. Two hanging beam feet are installed on the side of each vertical frame opposite the flow hole, and the two hanging beam feet are respectively close to the two corners of the flow hole on the same side. Two hanging beams are installed on each of the two sides of the vertical horizontal plane of the stacked beam door leaf, and the two hanging beams are respectively close to the two corners of the same side of the stacked beam door leaf; Each hanging beam is matched with its corresponding hanging beam support; Furthermore, the cross-section of the stacked beam door leaf is in the shape of a truncated pyramid, and the smaller quadrilateral plate faces the stacked beam door frame; The hanging beam consists of two parts. The cross-section of the part connecting the hanging beam to the stacked beam door leaf is parallelogram-shaped. In the vertical direction, the angle formed between the bottom of the hanging beam connecting part and the stacked beam door leaf is an acute angle. The part of the hanging beam extending out of the stacked beam door leaf is a rod-shaped structure. Furthermore, the cross-section of the hanging beam support is parallelogram-shaped. In the vertical direction, the angle formed between the top of the hanging beam support and the stacked beam door frame is an acute angle. When the rod-like structure of the hanging beam is erected on the top of the hanging beam support, the stacked beam door leaf slides downward along the acute angle side until the stacked beam door leaf is tightly fitted with the horizontal frame of the stacked beam door frame. Furthermore, an I-shaped hanging space is formed between the four hanging beams on the surface of the stacked beam door leaf. The hook beam is also I-shaped. The part of the hook beam used to hook the stacked beam door leaf consists of four hook claws. When the hook beam hooks the stacked beam door leaf, in the vertical direction, all four hook claws are placed below the hanging beam. Furthermore, several steel wire ropes are installed at the top of the hook beam. The connecting end of the steel wire rope is fixed to the hook beam, and the tensioning end is connected to the winch located at the top of the concrete pier at the hydropower station's water intake. The hook claw of the hook beam has a parallelogram cross-section, which matches the shape of the connection part of the hanging beam; Furthermore, it also includes a control system, which includes a stacked beam door leaf IC chip, a stacked beam door frame IC chip, and a hook beam IC card reader. The stacked beam door leaf IC chip is installed at the center of the stacked beam door leaf, the stacked beam door frame IC chip is installed at the center of the horizontal frame located vertically above, and the hook beam IC card reader is installed at the center of the hook beam. The hook beam IC card reader generates a magnetic field, and the stacked beam door leaf IC chip and the stacked beam door frame IC chip communicate with the control terminal after sensing the magnetic field. A stratified water intake control method, employing any of the fully automatic stratified water intake stacked beam gate systems described above, specifically includes the following steps: Step S1: In the vertical direction, define the bottommost stacked beam door as the first layer from bottom to top, then the topmost stacked beam door is the second layer. n layer; Step S2, determine the position of the current water level relative to the stacked beam gate, defined as the first... j layer, At the same time, determine the location of the overlapping beam door that needs to be opened, and define it as the first... k layer, ; Step S3: The control terminal sends a start command to the winch, controlling the hook beam to move vertically.

Step S6: The winch controls the hook beam to move upward, and the hook claws of the hook beam hook onto the first... k The overlapping beam door leaf of a tiered beam door; Step S7: The control terminal sends a translation command to the winch, and the hook beam drives the stacked beam gate leaf to translate. Once the stacked beam gate leaf has translated to the height distance of the stacked beam gate frame, the control terminal sends a vertical movement command to the winch, and the hook beam drives the stacked beam gate leaf to continue lifting towards the hydropower station's power generation intake until it reaches the... Location of the stacked beam door; Step S8: The control terminal sends a translation command to the winch until the stacked beam door leaf is aligned with the first...

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] As described in the background section, existing systems for stratified water intake typically have limited functionality, often only capable of simple water blocking and intake, making it difficult to meet the demands of stratified water intake. Furthermore, precise control of the intake depth and volume is challenging. While some upgraded technologies have been implemented, their extensive use of complex electrical and hydraulic systems has led to issues such as oil leaks and water ingress, significantly reducing the system's lifespan and causing pollution problems in upstream reservoirs, thus deviating from the original intention of providing technological support for ecological and environmental protection.

[0014] To address the aforementioned issues, this application provides a fully automatic tiered water intake stacked beam gate system and a tiered water intake control method. By setting multiple stacked beam gate leaves 1, tiered water intake is achieved, allowing for the acquisition of water sources at different depths according to actual needs, satisfying diverse water intake scenarios, and flexibly switching between water blocking and water intake states, thus enriching its functionality. Furthermore, the entire system does not contain mechanical gears or hydraulic systems, avoiding problems such as jamming, oil leakage, and water ingress during operation.

[0015] The preferred implementation structure provided in this application is as follows: Figures 1-7 As shown, the system includes several stacked beam gate frames 2, several stacked beam gate leaves 1, and hook beams 3. For ease of description, two directions are defined: one perpendicular to the horizontal plane and the other parallel to the horizontal plane. Several stacked beam gate frames are sequentially stacked from top to bottom within the stacked beam gate slot inside the power plant's water intake. Each stacked beam gate frame contains a stacked beam gate leaf, forming a stacked beam group. When the stacked beam gate slot is full of stacked beam groups, the stacked beam gate closes, achieving a water-blocking function. The hook beams are matched with the stacked beam gate leaves; by lifting the stacked beam gate leaves with the hook beams, the stacked beam gate opens, enabling water intake.

[0016] The design of stacked beam door frames from top to bottom makes the entire beam door system more stable, better able to withstand water pressure, and ensures the safety and reliability of the system during long-term use. Each beam door frame has a built-in beam door leaf, providing a precise installation position for the leaf. This helps ensure that the leaf accurately matches the frame when closed. Most importantly, by lifting part of the leaf, the system can flexibly switch between water blocking and water intake states as needed.

[0017] The above is the biggest innovation of this application. The overlapping beam gate leaf at different positions corresponds to water depths of different depths. By lifting the overlapping beam gate leaf at the corresponding position according to actual needs, water sources at different depths can be obtained, realizing layered water intake.

[0018] In the structural design for implementing stratified water intake, to ensure the service life of the entire system, this application provides several hanging beams 12 on the surface of each stacked beam door leaf and several hanging beam supports 22 on the vertical sidewall of each stacked beam door frame. The number and position of the hanging beams and hanging beam supports are matched. When the stacked beam door leaf is embedded in the stacked beam door frame, the hanging beams are supported on the hanging beam supports, and the hanging beams slide against the inner side of the hanging beam supports, simultaneously driving the stacked beam door leaf to slide vertically downwards until the surface of the stacked beam door leaf is tightly fitted with the stacked beam door frame. The entire opening and closing process involves only the door panel structure and does not involve underwater operations of the electrical and hydraulic systems, making the entire system reliable, durable, and easy to maintain.

[0019] Meanwhile, the operation method of lifting the laminated gate leaf in this application is to use a hook beam to lift it. That is, a hanging space is formed between several hanging beams arranged on the surface of the laminated gate leaf. The shape of the hook beam matches the hanging space. When the hook beam is embedded in the set hanging space of the laminated gate leaf, the hook beam is lifted to lift the laminated gate leaf, and the laminated gate is opened to achieve the water intake function.

[0020] Next, the above structure will be described one by one. First is Figure 2 The shown laminated gate frame structure is in an overall "hui" - shaped structure. Its center is a square through - flow hole, and the periphery of the through - flow hole is a frame. Define the direction of water flow into the laminated gate frame as the upstream of the laminated gate frame, then the direction of water flow out is the downstream of the laminated gate frame; On both sides perpendicular to the horizontal plane at the upstream of the laminated gate frame, protruding vertical frames are provided. On one side of each vertical frame relative to the through - flow hole, two hanging beam supports are installed, and the two hanging beam supports are respectively close to the two corner positions of the through - flow hole on the same side; On the two side edges perpendicular to the horizontal plane of the laminated gate leaf, two hanging beams are respectively installed, and the two hanging beams are respectively close to the two corner positions on the same side of the laminated gate leaf; Each hanging beam matches the corresponding hanging beam support.

[0021] Regarding the design concept of the laminated gate frame, essentially, a hole is drilled in the center of the flat laminated gate for water flow through. The design of the vertical frame provides the supporting force for fixing the hanging beam supports, and the upper and lower horizontal frames are combined with the embedded laminated gate leaf, ultimately playing a role in blocking water.

[0022] From Figure 2 the side view Figure 2 c, it can be seen that the horizontal frame of the laminated gate frame is a side wall with an inclination. Therefore Figure 1 as shown, the cross - section of the laminated gate leaf is designed to be trapezoidal - prism - shaped, and the quadrilateral plate surface with a smaller area faces the laminated gate frame; The trapezoidal - prism - shaped means that the upper and lower bases are similar quadrilaterals, and the four side faces are trapezoids. Then when the laminated gate leaf is embedded in the laminated gate frame, the quadrilateral of the laminated gate leaf can closely fit the laminated gate frame. In addition, the through - flow hole of the laminated gate frame contracts in the downstream direction, and the contraction flow will enhance the water flow stability and reduce the risk of flow - induced vibration of the laminated gate frame caused by water flow.

[0023] Due to the inclined design of the side of the laminated gate frame and the laminated gate leaf, a sliding action is required when placing the laminated gate leaf in the laminated gate frame. Therefore, corresponding supporting designs are also made for the structure of the hanging beam supports and the hanging beams. Regarding the hanging beam supports, the cross - section of the hanging beam supports is in a parallelogram shape. In the vertical direction, the included angle formed between the top of the hanging beam support and the laminated gate frame is an acute angle. The hanging beam includes two parts. The cross - section of the part connected to the laminated gate leaf is in a parallelogram shape. In the vertical direction, the included angle formed between the bottom of the hanging beam connection part and the laminated gate leaf is an acute angle. The part of the hanging beam extending out of the laminated gate leaf is a rod - shaped structure. When the rod - shaped structure of the hanging beam is placed on the top of the hanging beam support, the laminated gate leaf slides downward along the acute - angle side until the laminated gate leaf closely fits the horizontal frame of the laminated gate frame ( Figure 3 (As shown).

[0024] According to the preferred embodiment provided in this application, an I-shaped hanging space is formed between the four hanging beams on the surface of the stacked beam door leaf. Therefore, the hook beam is also I-shaped, and the part of the hook beam used to hook the stacked beam door leaf is defined as four hook claws 32. When the hook beam hooks the stacked beam door leaf, in the vertical direction, all four hook claws are placed at the top of the hanging beam. At this time, after the hook beam and the stacked beam door leaf are combined, the four corners of the "I" shape are in contact with the stacked beam door leaf, ensuring that the hook beam can firmly hook the stacked beam door leaf and prevent the stacked beam door leaf from falling or sliding left and right.

[0025] Preferably, several steel wire ropes 31 are installed at the top of the hook beam, and signal cables are arranged in parallel inside the steel wire ropes. Figure 5 As shown, the connecting end of the wire rope is fixed to the hook beam, and the tensioning end is connected to the winch 34 located on top of the concrete pier 4 at the water intake of the hydropower station; the hook claw of the hook beam has a parallelogram shape, which matches the shape of the connecting part of the hanging beam.

[0026] To achieve full automation of the entire system, a control system is also included. Figure 10 As shown, it includes a stacked beam door leaf IC chip 11, a stacked beam door frame IC chip 21, and a hook beam IC card reader. The stacked beam door leaf IC chip is installed at the center of the stacked beam door leaf, the stacked beam door frame IC chip is installed at the center of the horizontal frame located vertically above, and the hook beam IC card reader is installed at the center of the hook beam. The stacked beam door leaf IC chip and the stacked beam door frame IC chip do not require power supply and have independent coils inside. The hook beam IC card reader generates a magnetic field, which the IC chip senses, thereby communicating with the control terminal (similar to swiping an ID card). The hook beam IC card reader can read the identification identifier of each stacked beam door leaf IC chip and the stacked beam door frame IC chip; the control terminal can control the winch to move, and the winch can rotate to control the hook beam to move up and down (vertically), and can also move the hook beam forward and backward (translational).

[0027] To further improve the efficiency of stratified water intake, this application provides a stratified water intake control method, which employs the aforementioned fully automatic stratified water intake stacked beam gate system, specifically including the following steps: Step S1: In the vertical direction, define the bottommost stacked beam door as the first layer from bottom to top, then the topmost stacked beam door is the second layer. n layer; Step S2, determine the position of the current water level relative to the stacked beam gate, defined as the first... j layer, At the same time, determine the location of the overlapping beam door that needs to be opened, and define it as the first... k layer, ; Step S3: The control terminal sends a start command to the winch, controlling the hook beam to move vertically. During the movement, the hook beam IC card reader scans the IC chips of the stacked beam door leaf and the stacked beam door frame until it reaches the [missing information - likely a specific location or step]. k Location of the stacked beam door; Step S4: The control terminal continues to send commands to the winch, controlling the hook pawl of the hook beam to move downwards in the vertical direction to the next step. k Below the hanging beam matching the stacked beam door; Step S5: The control terminal sends a translation command to the winch until the hook beam is aligned with the first... k The overlapping beams of the door panels fit together. Step S6: The winch controls the hook beam to move upward, and the hook claws of the hook beam hook onto the first... k The overlapping beam door leaf of a tiered beam door; Step S7: The control terminal sends a translation command to the winch, and the hook beam drives the stacked beam gate leaf to translate. Once the stacked beam gate leaf has translated to the height distance of the stacked beam gate frame, the control terminal sends a vertical movement command to the winch, and the hook beam drives the stacked beam gate leaf to continue lifting towards the hydropower station's power generation intake until it reaches the... Location of the stacked beam door; Step S8: The control terminal sends a translation command to the winch until the stacked beam door leaf is aligned with the first... When the stacked beam door frames overlap, the control terminal sends a vertical movement command to the winch. The hook beam moves downwards in the vertical direction, embedding the stacked beam door leaf into the first... Inside the layered beam door frame; Step S9, the hook beam IC card reader reads the first... Stacked beam door leaf IC chip, the first The IC chip signal of the stacked beam door frame is confirmed by the signal transmission interval. Layered beam door leaf and the first The relative positions of the stacked beam door frames are verified to confirm the placement results.

[0028] After the entire stratified water intake process is completed, the hook beam continues to move downwards by the length of the parallelogram's base. Then, the winch moves horizontally upstream to disengage the hook beam from the stacked beam gate leaf. This completes one stacked beam gate leaf movement process, preparing for the next movement.

[0029] Finally, this application provides a specific embodiment in which a gantry crane on the top of a hydroelectric dam is used to stack the beam gate frame layer by layer into the beam gate slot. At this time, the beam gate is still in the open state. Figure 8 , Figure 9 As shown above. Hook beams are used to place the overlapping beam door leaves layer by layer onto the corresponding overlapping beam door frames. When the overlapping beam door is fully closed, as shown... Figure 7 , Figure 9As shown in the lower part. Assuming the water level is currently on the 25th floor, and we need to open the bottom 1st floor's stacked beam door, we only need to move the bottom 1st floor's stacked beam door to the 26th floor.

[0030] When the control terminal receives the instruction to move the first layer of stacked beam door leaf to the 26th layer, it controls the hook beam to move vertically downwards along the upstream of the stacked beam door. During the movement, the hook beam IC reader 33 scans the stacked beam door frame IC chip and the stacked beam door leaf IC chip that it passes through. It determines the current position of the hook beam itself based on the stacked beam door frame IC chip and determines the stacked beam door leaf that needs to be hooked based on the stacked beam door leaf IC chip.

[0031] When the hook beam descends to the bottom, the hook beam IC reader scans the IC chip of the first layer of stacked beam door leaf, determines the stacked beam door leaf that needs to be moved, and moves the hook beam down by the length of a parallelogram diagonal. At this time, the hook pawl of the hook beam is completely below the hanging beam of the stacked beam door leaf.

[0032] Control the winch to move horizontally downstream until the hook beam and the stacked beam door leaf are in contact (the distance between the IC chip signal of the first layer stacked beam door frame and the IC chip of the stacked beam door leaf is determined by the hook beam IC reader).

[0033] Move the hook beam upwards by the length of a parallelogram diagonal, at which point the hook beam's claws will completely hook onto the stacked beam door leaf.

[0034] The winch controls the hook beam to move the stacked beam door leaf upwards by the length of the base side of the parallelogram, lifting the stacked beam door leaf out of the stacked beam door frame. Then, the winch moves horizontally upstream by the height of the parallelogram. Subsequently, the hook beam drives the stacked beam door leaf to continue moving upwards until it reaches the position of the 26th stacked beam door frame.

[0035] The hook beam moves the stacked beam door leaf upwards by the length of the base of the parallelogram. Then, the winch moves horizontally downstream until the stacked beam door frame and the stacked beam door leaf are in contact (the distance is determined by the IC chip signal of the 26th stacked beam door frame read by the hook beam IC reader). Then, the hook beam moves the stacked beam door leaf downwards by the length of the base of the parallelogram, so that the 1st stacked beam door leaf is stably placed on the 26th stacked beam door frame.

[0036] After installation, the installation result is verified. The IC chip signal of the 26th layer stacked beam door frame and the IC chip signal of the 1st layer stacked beam door leaf are read by the hook beam IC reader. The relative distance between the 1st layer stacked beam door leaf and the 26th layer stacked beam door frame is confirmed by the signal reception time interval × the wave speed of signal transmission, ensuring that the 1st layer stacked beam door leaf is successfully installed.

[0037] In summary, the fully automatic tiered water intake stacked beam gate system provided in this application features sequentially stacked beam gate frames, enhancing overall structural stability and enabling it to withstand water flow pressure. The cooperation between the hanging beams and their supports guides and limits the movement of the stacked beam gate leaves, improving the structural strength of the stacked beam assembly and reducing frictional resistance. The stacked beam gate leaves can flexibly switch between water blocking and water intake states, achieving tiered water intake. Precise coordination of all parts ensures a tight fit between the stacked beam gate leaves and the gate frame, providing excellent sealing and reducing leakage. The matching of the hook beams with the hanging space facilitates the operation of the stacked beam gate leaves and allows integration with an automated control system for fully automatic operation, reducing manpower and time consumption and ensuring operational safety. The stacked beam gate frame structure facilitates system expansion and maintenance; stacked beam assemblies can be added or removed as needed, and maintenance of a single gate frame does not affect overall operation.
