Description

Technical Field

[0001] This application relates to the field of water intake technology in water conservancy and hydropower projects, and in particular to a gate device for stratified water intake. Background Technology

[0002] To reduce the impact on the ecological environment of downstream water conservancy and hydropower projects, gate devices can adopt stratified water intake technology, which allows for precise control of the intake water temperature by taking water from different heights.

[0003] In related technologies, gate devices are equipped with water intakes at different heights, allowing for tiered water intake by opening these intakes. However, this method results in fixed intake locations, making it difficult to precisely control the intake elevation. Summary of the Invention

[0004] The purpose of this application is to provide a gate device for stratified water intake, which aims to solve the problem of how to accurately control the water intake elevation.

[0005] To achieve the above objectives, this application adopts the following technical solution: This application provides a gate device for stratified water intake.

The drive device is connected to the plurality of gate units and can drive at least one of the gate units arranged continuously from the top to the bottom of the gate to move, so as to switch the gate between an open state and a closed state.

[0006] The gate device provided in this embodiment can be equipped with a drive mechanism. This drive mechanism drives at least one gate unit among multiple gate units to rise vertically, forming a water passage between the gate units, thus switching the gate to the open state. This configuration allows for adjustment of the gate's water intake position by controlling the number of rising gate units, and adjustment of the gate's water intake elevation by controlling the displacement of the rising gate units. The position and size of the water passage are not limited by the height of the gate units, enabling stepless adjustment of the water intake elevation. This allows for precise stratified water intake and facilitates accurate control of the water temperature. After the water intake operation is completed, the gate device can also drive at least one gate unit among the multiple gate units to fall vertically, switching the gate to the closed state.

[0007] Furthermore, when at least one gate unit moves upward to open the gate, the water passage within the specified elevation is fully opened, and no gate unit obstructs or hinders the water flow, thereby improving the accuracy and stability of the water intake speed and flow rate.

[0026] In the embodiments of this application, the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," "fourth," "fifth," and "sixth" may explicitly or implicitly include one or more of that feature.

[0027] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0029] In the embodiments of this application, "parallel," "perpendicular," and "equal" include the described situation and situations similar to the described situation, where the range of similarity is within an acceptable deviation range, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, where the acceptable deviation range for approximate parallelism can be, for example, a deviation within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, where the acceptable deviation range for approximate perpendicularity can also be, for example, a deviation within 5°.

[0030] Early hydropower stations primarily used single-elevation water intake, which made it difficult to accurately regulate the water temperature and easily impacted the downstream ecological environment. In recent years, with the construction of high dams and large reservoirs and the need for ecological protection, stratified water intake technology has been rapidly iterating. It has gradually evolved from the method of taking surface water by opening and closing stacked beam gates to a modular method that flexibly increases or decreases the number of water intake layers, in order to achieve water temperature regulation and reduce the impact on the downstream ecology.

[0031] Currently, the layered water intake system mostly adopts the stacked beam gate form. This method uses a modular design, which breaks down the overall gate into multiple independent gate modules. At the water intake, there are multiple stacked beam gates that can be raised and lowered along the height direction. When water intake is carried out, the stacked beam gates above the water intake position are lifted and moved away by lifting equipment to achieve water intake.

[0032] However, this water intake method can only control the water intake depth according to the height of each stacked beam door, and cannot achieve stepless adjustment of the water intake height. In addition, when taking water, it is necessary to start moving from the stacked beam door above, and can only take surface water, making it difficult to adjust the water temperature.

[0033] In related technologies, some gate devices have fixed water intakes at different elevations, allowing water to be drawn from the middle. However, the water intake positions of these gate devices are fixed, the number of water intakes is limited, and the water intake elevation is relatively uniform. Some gate devices use multiple layered gates installed at fixed points. Water is drawn by rotating the gate leaf structure at a certain angle. The water intake elevation of this type of gate device is limited to the height of the opened gate, and it cannot achieve stepless adjustment, making it difficult to meet the water intake requirements at specific elevations. Furthermore, the opened gate leaf structure can obstruct water flow, and the gate leaf itself is prone to vibration under the action of water flow, affecting the accuracy of water flow velocity and flow rate.

[0034] Based on this, this application provides a gate device 100 for stratified water intake. Please refer to... Figures 1-3 , Figure 1 This is a schematic diagram of the structure of a gate device 100 provided in an embodiment of this application. Figure 2 for Figure 1 The diagram shows a partial structural front view and top view of a gate device 100. Figure 3 for Figure 1 The diagram shows a partial front and top view of another gate device 100, which includes a gate 10 and a drive unit 20. The gate 10 includes a plurality of gate units 11 arranged along the height direction and connected sequentially. The drive unit 20 is connected to the plurality of gate units 11 and is capable of driving at least one of the gate units 11 arranged continuously from the top to the bottom of the gate 10 to move, so that the gate 10 switches between an open state and a closed state.

[0035] The gate device 100 provided in this embodiment can be equipped with a drive device 20. The drive device 20 drives at least one of the multiple gate units 11 to rise along the height direction, forming a water passage between the multiple gate units 11, that is, switching the gate 10 to the open state. With this configuration, the water intake position of the gate 10 can be adjusted by controlling the number of rising gate units 11, and the water intake elevation of the gate 10 can be adjusted by controlling the displacement of the rising gate units 11. The position and size of the water passage are not limited by the height of the gate units 11, enabling stepless adjustment of the water intake elevation, thereby achieving precise stratified water intake and facilitating accurate control of the water temperature.

[0036] After the water intake operation is completed, the gate device 100 can also rely on its own drive device 20 to drive at least one of the multiple gate units 11 to fall back along the height direction, so as to switch the gate 10 to the closed state.

[0037] Furthermore, when at least one gate unit 11 moves upward to open the gate 10, the water passage within the specified elevation is fully opened, and no gate unit 11 obstructs or hinders the water flow, thereby improving the accuracy and stability of the water intake speed and flow rate.

[0038] In some embodiments, each gate unit 11 has the same structure, which facilitates manufacturing. Each gate unit 11 is also assigned a unique number to distinguish and identify different gate units 11, so as to send independent control commands to different gate units 11.

[0039] In some embodiments, the drive device 20 includes a plurality of drive members 21, a plurality of first transmission members 22, and a second transmission member 23 that cooperates with each of the plurality of first transmission members 22. The plurality of drive members 21 correspond one-to-one with the plurality of first transmission members 22 and the plurality of gate units 11. Each drive member 21 is connected to the corresponding first transmission member 22, and each first transmission member 22 is connected to the corresponding gate unit 11. The second transmission member 23 extends along the height direction, and each drive member 21 can drive the corresponding first transmission member 22 to move relative to the second transmission member 23 along the height direction.

[0040] In this configuration, each gate unit 11 can be equipped with an independent drive component 21 and a first transmission component 22. When the gate 10 needs to be opened, different gate units 11 can be controlled to move along the height direction according to different requirements of water intake location and elevation, thereby opening water passages at different positions. This enables precise control and stepless adjustment of the gate 10, which helps to accurately regulate the water intake temperature. Furthermore, multiple first transmission components 22 share a single second transmission component 23, which simplifies the structure of the drive device 20 and reduces its size and installation difficulty.

[0041] In other embodiments, the drive device 20 may include a plurality of drive members 21, a plurality of first transmission members 22, and a plurality of second transmission members 23, wherein the plurality of drive members 21 correspond one-to-one with the plurality of first transmission members 22, the plurality of second transmission members 23, and the plurality of gate units 11. This arrangement allows each gate unit 11 to be moved by an independent drive member 21, first transmission member 22, and second transmission member 23, resulting in more flexible adjustment.

[0042] In some other embodiments, the drive device 20 may include a drive member 21, a plurality of first transmission members 22 and second transmission members 23, wherein the drive member 21 may cooperate with different first transmission members 22 to cause different gate units 11 to move relative to the second transmission members 23. This application does not limit this.

[0043] In some embodiments, the number of first transmission members 22 can be twice the number of gate units 11, and two second transmission members 23 can be provided. Each gate unit 11 is provided with one driving member 21 and two first transmission members 22. The two first transmission members 22 are respectively provided on opposite sides of the gate unit 11 along the width direction, and the two second transmission members 23 are also respectively provided on opposite sides of the gate unit 11 along the width direction.

[0044] The driving component 21 can simultaneously drive the two corresponding first transmission components 22 to move along the height direction. In this way, the gate unit 11 can be driven on both sides along the width direction, thereby improving the stability of the gate unit 11's movement and reducing the gate unit 11's skewness or jamming.

[0045] In some embodiments, the number of first transmission members 22 can be four times the number of gate units 11, and each gate unit 11 has two first transmission members 22 on opposite sides along the width direction, which further improves the motion stability of the gate unit 11.

[0046] In other embodiments, the number of first transmission members 22 may be six or eight times the number of gate units 11, etc., and this application does not limit this.

[0047] In some embodiments, when the number of first transmission members 22 can be four times the number of gate units 11, the number of drive members 21 can be set to twice the number of gate units 11, and each drive member 21 can be drivenly connected to two first transmission members 22 in the width direction of the gate unit 11. In this way, the load on each drive member 21 can be reduced and the service life of the drive member 21 can be extended.

[0048] To ensure the consistency of movement of multiple first transmission components 22 corresponding to the same gate unit 11, the drive device 20 may also include a synchronous shaft 27, which is connected between two drive components 21 on the gate unit 11 to ensure that the output torque of the two drive components 21 is the same.

[0049] Please refer to Figures 2-4 , Figure 4 for Figure 1 The diagram shows a partial structural side view of a gate device 100. In some embodiments, the first transmission member 22 may include a gear, and the second transmission member 23 may include a rack that meshes with the gear. When a gate unit 11 needs to move upward, the corresponding drive member 21 can drive the corresponding gear to mesh on the rack, thereby causing the gate unit 11 to move relative to the second transmission member 23 in the height direction, thus opening the gate 10.

[0050] The gear and rack mechanism allows for precise control of the transmission ratio between the first transmission component 22 and the second transmission component 23, further improving the accuracy of the gate unit 11's displacement and thus precisely regulating the water intake temperature. Furthermore, the gear and rack transmission design is simple, reducing assembly and maintenance complexity.

[0051] In other embodiments, the first transmission member 22 may be a sprocket, and the second transmission member 23 may be a chain that cooperates with the sprocket, with the sprocket moving relative to the chain in the height direction. This application does not limit the specific structure of the first transmission member 22 and the second transmission member 23.

[0052] In some embodiments, the gate device 100 may further include a support frame 30 extending in the height direction, and a plurality of gate units 11 are configured to cooperate with the support frame 30. When the driving device 20 drives the gate unit 11 to slide in the height direction, the support frame 30 can guide and limit the gate unit 11 to prevent the gate unit 11 from moving laterally.

[0053] In some embodiments, the second transmission member 23 may be fixedly disposed on the support frame 30, and the driving member 21 may drive the first transmission member 22 to move along the extension direction of the second transmission member 23.

[0054] In some embodiments, the drive device 20 further includes a plurality of deceleration structures 24, which correspond one-to-one with a plurality of gate units 11, and each deceleration structure 24 is drivenly connected between the corresponding drive member 21 and the first drive member 22.

[0055] The deceleration structure 24 is connected between the drive component 21 and the first transmission component 22, which can reduce the rotational speed of the drive component 21 to the first transmission component 22, thereby reducing the moving speed of the gate unit 11 and improving the accuracy of the water intake elevation.

[0056] Furthermore, the deceleration structure 24 can increase the output torque of the drive device 20 and improve the load capacity of the drive device 20, so that the power output by the drive device 20 can overcome the gravity of the gate unit 11 and the friction between the first transmission member 22 and the second transmission member 23, so that the gate unit 11 can move upward in the height direction.

[0057] In some embodiments, the reduction structure 24 includes a worm gear mechanism.

[0058] The worm gear mechanism has excellent self-locking performance. The reduction structure 24 is configured as a worm gear structure, which can lock the gate unit 11 in the stopped position when the drive component 21 stops rotating. This prevents the gate unit 11 from sliding down under gravity, which helps ensure the accuracy of the water intake elevation and protects the drive component 21. Furthermore, due to the large reduction ratio of the worm gear structure, it can effectively achieve speed reduction and torque increase, thereby improving the load capacity of the drive device 20.

[0059] In addition, the worm gear mechanism can realize the reversal of the drive component 21 to the first transmission component 22, which facilitates the layout of the drive component 21.

[0060] Because the worm gear mechanism has a self-locking function, when the gate device 100 malfunctions and causes the drive component 21 to stop rotating, the gate unit 11 is locked in the position where the drive component 21 stops rotating under the action of the worm gear mechanism, making it difficult to move the gate unit 11 out for maintenance.

[0061] Therefore, in some embodiments, the drive device 20 further includes a plurality of clutch structures 25, which correspond one-to-one with a plurality of gate units 11. Each clutch structure 25 is connected between the corresponding deceleration structure 24 and the first transmission member 22, so that the deceleration structure 24 and the first transmission member 22 are coupled or separated.

[0062] In this way, when maintenance is required, the clutch structure 25 can be operated to separate the deceleration structure 24 and the first transmission member 22. At this time, under the action of external force, the first transmission member 22 can move relative to the second transmission member 23, so as to lift the gate unit 11 out of the water for maintenance.

[0063] When the gate device 100 is in normal operation, the clutch structure 25 is in the engaged state. When the gate device 100 is in an abnormal operation state, the clutch structure 25 can be in the disengaged state. The disengagement of the deceleration structure 24 and the first transmission component 22 can be achieved by the drive device 20, or by the drive of an external lifting device.

[0064] In some embodiments, the gate device 100 may include a lifting lug 12, which is disposed on the gate unit 11 and is adapted to connect a lifting device so that the lifting device is fixedly connected to the gate unit 11, so as to facilitate the lifting of the gate unit 11.

[0065] In some embodiments, the number of lifting lugs 12 can be set to multiple, with each lifting lug 12 corresponding to a different gate unit 11. When a gate unit 11 malfunctions, an external lifting device can be connected to the lifting lug 12 on the corresponding gate unit 11 to lift the gate unit 11 out of the water and to the maintenance area for repair.

[0066] In some embodiments, an external lifting device can lift both the abnormal gate unit 11 and the gate unit 11 located above it in the height direction out of the water, so that the abnormal gate unit 11 can be lifted out of the water.

[0067] In some other embodiments, the support frame 30 may have an opening, through which an external lifting device can remove the malfunctioning gate unit 11 from the support frame 30 and then lift it out of the water. This application does not further limit the method of removing the malfunctioning gate unit 11 from the water.

[0068] In some embodiments, the lifting lug 12 may include a lifting lug hole, the axis of which is aligned with the height direction. When the gate unit 11 malfunctions and needs to be lifted out, the lifting equipment operates a hydraulic automatic detachment beam that passes through the lifting lug hole to fix the hydraulic automatic detachment beam to the gate unit 11.

[0069] In some embodiments, the clutch structure 25 includes a clutch connected between the reduction structure 24 and the first transmission member 22, and a clutch operating lever connected to the clutch. The clutch operating lever can control the clutch to couple or disengage the reduction structure 24 from the first transmission member 22.

[0070] The clutch operating lever is located on the outside of the lifting lug hole. When the hydraulic automatic disengagement beam is inserted into the lifting lug hole, pushing the clutch operating lever can disengage the deceleration structure 24 from the first transmission component 22, releasing the self-locking state of the drive device 20. At the same time, since the hydraulic automatic disengagement beam has completed its engagement and fixation with the lifting lug hole, it can be ensured that the gate unit 11 will not slide down after the self-locking is released.

[0071] In some embodiments, when the hydraulic automatic disengagement beam disengages from the lifting lug hole, the clutch can automatically reset, restoring the self-locking function of the deceleration structure 24.

[0072] In some embodiments, the gate 10 further includes a sealing structure 26, which is disposed on the side of the gate unit 11 facing the adjacent gate unit 11, for sealing two adjacent gate units 11.

[0073] When there is no need to open the water passage between adjacent gate units 11, the sealing structure 26 can prevent water from flowing out from the gap between the gate units 11, thereby further ensuring the accuracy of the water intake temperature.

[0074] In some embodiments, there are multiple sealing structures 26, and each sealing structure 26 is provided in a one-to-one correspondence with a multiple gate unit 11.

[0075] In some embodiments, the sealing structure 26 may include a first sealing part 261 and a second sealing part 262, which are respectively disposed on the upper and lower sides of the gate unit 11 along the height direction.

[0076] For example, if the first sealing part 261 is disposed on the upper side of the gate unit 11 and the second sealing part 262 is disposed on the lower side of the gate unit 11, then the first sealing part 261 can seal the gap between the gate unit 11 and the upper adjacent gate unit 11, and the second sealing part 262 can seal the gap between the gate unit 11 and the lower adjacent sealing unit.

[0077] In some embodiments, the sealing structure 26 of each gate unit 11 includes a first sealing part 261 and a second sealing part 262. The first sealing part 261 of each gate unit 11 may cooperate with the second sealing part 262 of the adjacent gate unit 11 on the side facing the first sealing part 261.

[0078] For example, if the first sealing part 261 is disposed on the upper side of the gate unit 11 and the second sealing part 262 is disposed on the lower side of the gate unit 11, then the first sealing part 261 of the gate unit 11 can cooperate with the second sealing part 262 of the adjacent gate unit 11 on the upper side of the gate unit 11 to improve the sealing performance between the two gate units 11.

[0079] In some embodiments, at least one of the first sealing portion 261 and the second sealing portion 262 is an elastic structure.

[0080] At least one of the first sealing part 261 and the second sealing part 262 is an elastic structure, so that when two adjacent gate units 11 are connected, the elastic structure can be squeezed to further reduce the gap between the two adjacent gate units 11.

[0081] For example, the first sealing part 261 is configured as a sealing seat plate, and the second sealing part 262 is configured as a rubber seal. When two adjacent gate units 11 are connected, the rubber seal abuts against the sealing seat plate and is compressed and deformed under the action of gravity, thereby reducing the gap between the first sealing part 261 and the second sealing part 262.

[0082] In some embodiments, the wall surface of the support frame 30 facing the gate unit 11 may also be provided with a sealing element to achieve a seal between the gate unit 11 and the support frame 30.

[0083] For example, the seal may include rubber parts, silicone parts, etc., and this application does not limit it.

[0084] The sealing structure 26 between adjacent gate units 11 can achieve inter-section water sealing of gate units 11, and the sealing element between the support frame 30 and gate unit 11 can achieve water sealing on both sides. The two work together to achieve the water blocking effect of the overall gate 10.

[0085] When multiple gate units 11 are connected in sequence and cooperate with the support frame 30 to close the water passage, that is, when the gate 10 is in the closed state, the gate device 100 can function as a maintenance gate. When maintenance is required downstream of the gate device 100, the gate 10 can be adjusted to the closed state to block the upstream water flow. At this time, the downstream water can be drained for maintenance.

[0086] Please refer to Figures 1-4 In some embodiments, the gate device 100 may include a controller 50, which may be electrically and communicatively connected to the gate 10 and / or the drive device 20, so that the operator can send control commands to the drive device 20 through the controller 50.

[0087] In some embodiments, the controller 50 may include a central control unit and an independent control unit. The central control unit is located on the water surface, and the independent control unit is located on the gate unit. The operator above the water surface sends control commands to the independent control unit through the central control unit or through intelligent calculations by the central control unit. The independent control unit on the gate unit controls the drive device 20 to drive the gate unit to move, thereby reducing the intensity of manual operation.

[0088] In some embodiments, the gate device 100 further includes a power supply module 40, which can be electrically connected to the drive device 20 to supply power to the drive device 20.

[0089] In some embodiments, the power supply module 40 may include a power supply rail 42 and a contact power taking part 43, which slides with the power supply rail 42 and is electrically connected to the drive device 20. When the gate unit 11 moves relative to the support frame 30, the contact power taking part 43 can slide within the power supply rail 42 to obtain the power supplied by the power supply rail 42 and provide the power to the drive device 20.

[0090] In some embodiments, there are multiple contact power taking parts 43, and the driving device 20 includes multiple driving members 21. The multiple contact power taking parts 43 correspond one-to-one with multiple gate units 11 and multiple driving members 21. When the gate unit 11 moves, the contact power taking part 43 corresponding to the gate unit 11 slides relative to the power supply track 42 to transfer the power provided by the power supply track 42 to the corresponding driving device 20.

[0091] In some embodiments, the power supply track 42 may be disposed on the support frame 30 and extend along the height direction. A sliding contact line may be arranged inside the power supply track 42, which is electrically connected to the controller 50 on the water. When the contact power taking part 43 slides inside the power supply track 42, it can contact the sliding contact line to obtain power.

[0092] In some embodiments, the power supply module 40 further includes an energy storage structure 41, which is disposed on the gate 10 and electrically connected to the drive device 20. The energy storage structure 41 can transmit the stored electrical energy to the drive device 20, so that the drive device 20 can drive the gate unit 11 to move.

[0093] In some embodiments, multiple energy storage structures 41 can be configured, with each energy storage structure 41 corresponding to a multiple gate unit 11. Each energy storage structure 41 is disposed on the corresponding gate unit 11 and is electrically connected to the corresponding drive unit 21.

[0094] In some embodiments, the energy storage structure 41 can be an independent energy storage structure 41 with its own power supply, which supplies power to the drive device 20 with its own power.

[0095] In other embodiments, the energy storage structure 41 can be electrically connected to the contact power take-up part 43. When the gate unit 11 moves relative to the power supply slide rail, it can store the electrical energy obtained by the contact power take-up part 43 into the energy storage structure 41, that is, charge the energy storage structure 41. When the drive unit 21 needs electrical energy, the energy storage structure 41 transfers the stored electrical energy to the drive unit 21 so that the drive unit 21 can operate normally.

[0096] For example, the energy storage structure 41 can be configured as a battery pack.

[0097] In some embodiments, the power supply module 40 may further include a generator 44, which is disposed in the gate unit 11 and electrically connected to the drive device 20.

[0098] In some embodiments, the generator 44 can generate electricity from water. The generator 44 can be equipped with a water outlet. When water flows through the water outlet, the generator 44 can convert the kinetic energy of the water flow into electrical energy to generate electricity.

[0099] In other embodiments, the generator 44 can generate electricity mechanically. When the gate unit 11 moves, the generator 44 can convert the kinetic energy of the gate unit 11 into electrical energy to generate electricity.

[0100] In some embodiments, the generator 44 is directly electrically connected to the drive unit 20 and directly supplies power to the drive unit 21.

[0101] In other embodiments, generator 44 is electrically connected to energy storage structure 41 to store electrical energy in energy storage structure 41.

[0102] In some embodiments, there are multiple generators 44, and each generator 44 corresponds to a multiple gate unit 11. Each energy storage structure 41 is disposed on the corresponding gate unit 11 and is electrically connected to the corresponding energy storage structure 41 or drive unit 21.

[0103] In some embodiments, the gate device 100 may include a communication module 60, which is disposed in the gate unit 11 and electrically connected to the controller 50 and the drive device 20. The communication module 60 is used to receive instructions from the controller 50 and control the drive device 20 to output power.

[0104] In some embodiments, the number of communication modules 60 can be set to multiple, with each communication module 60 corresponding to a multiple gate unit 11, so as to realize independent control of multiple gate units 11.

[0105] In some embodiments, the communication module 60 can be configured as a wired communication module. For example, a communication harness can be disposed on the support frame 30, with one end of the communication harness connected to the controller 50 and the other end connected to an independent control unit, through which the drive unit 21 is controlled.

[0106] In other embodiments, the communication module 60 may be configured as a wireless communication module. For example, the communication module 60 may be a sonar communication module, a visible light communication module, or an electromagnetic communication module, etc.

[0107] In some embodiments, the gate device 100 may further include a position detection device, wherein the position detection module 70 is disposed on the gate unit 11 and is adapted to detect the position of the gate unit 11.

[0108] In this way, when the gate unit 11 moves, the position detection device can detect the position of the gate unit 11 in real time, thereby accurately controlling the output of the drive component 21 and accurately controlling the water intake elevation.

[0109] In some embodiments, the position detection module 70 can be connected to the communication module 60 to realize the real-time transmission of the position of the gate unit 11 to the controller 50, which facilitates monitoring and adjustment by staff.

[0110] In some embodiments, the gate device 100 may further include a magnetic scale, which is disposed on the support frame 30. The position detection device disposed on the gate unit 11 can cooperate with the magnetic scale disposed on the support frame 30 to achieve precise positioning of the gate unit 11.

[0111] In some embodiments, the gate device 100 further includes a temperature sensor 80, which is disposed on the gate 10 or the support frame 30 and is used to detect the water temperature at the location of the temperature sensor 80.

[0112] In some embodiments, multiple temperature sensors 80 may be configured, arranged along the height direction to detect water temperature at different depths. In other embodiments, the temperature sensors 80 may be distributed across the entire water depth range to detect water temperature throughout the entire depth range.

[0113] Temperature sensor 80 can be electrically connected to controller 50. Temperature sensor 80 can transmit the detected water temperature to controller 50. The operator determines the water intake temperature based on the detected water temperature across the entire water depth range. Once the water intake temperature is determined, it is input into controller 50. The system calculates the final position of each gate unit 11 and then issues a specified control to each gate unit 11 to operate to the specified final position, thereby enabling water to be drawn from the designated water temperature position while preventing water flow from other positions.

[0114] When the elevation of the Nth gate unit 11 is determined to be for water intake, the gate device 100 of this application starts from the first gate unit 11 at the top, and the first to (N-1)th gate units 11 are driven to move upward to the specified final position by their corresponding driving members 21, leaving the middle water passage position so that water of the specified temperature can pass through the gate 10.

[0115] With this gate device 100, water intake can be carried out in layers at all elevations, and the water intake position is infinitely adjustable, thereby ensuring the accuracy of the water intake position and the water intake volume. In addition, the water passage within the water intake elevation is fully open and unobstructed, reducing turbulence disturbance.

[0116] When the gate device 100 needs to completely block water, it falls down one by one from the (N-1)th gate unit 11 until it completely contacts and seals with the gate unit 11 below, thereby blocking all upstream water head and taking into account the function of maintenance gate 10.

[0117] In the description of the embodiments of this application, specific features, structures, materials or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0118] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
