Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, specifically to a combined stratified water intake gate. Background Technology

[0002] In large-scale water conservancy and hydropower projects, due to the considerable water depth, water bodies at different depths possess different characteristics. In order to extract relatively suitable water, it is often necessary to adopt a stratified water intake approach.

[0003] Traditional hydropower stations typically use stacked beam gates for tiered water intake. The drawback is that when drawing water in tiers, one or more stacked beam gates need to be installed or removed one by one, which is complicated and results in low water intake efficiency.

[0004] In addition, a type of tiered intake gate has been developed in the existing technology, which uses multiple rotatable gate leaves to draw water from bodies of water at different levels. The overall structure of this type of gate is relatively complex, its operation is inconvenient, and it requires a large driving force to achieve its purpose. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a combined stratified water intake gate.

[0006] The combined layered water intake gate provided by the present invention includes several gate components located at different heights;

[0007] Each gate assembly includes a gate body, a gate frame, a drive device, a first transmission structure, and a second transmission structure, with the gate body and the gate frame rotatably connected.

[0008] The driving device is fixedly connected to the door frame, and the second transmission structure is fixedly connected to the door body. The second transmission structure is circular or arc-shaped, and the center of the second transmission structure is located on the rotation axis of the door body. The driving device is connected to the first transmission structure and can drive the first transmission structure to rotate. The first transmission structure is connected to the second transmission structure. The driving device drives the first transmission structure and the second transmission structure to move relative to each other, thereby driving the door body to rotate.

[0009] In this technical solution, by adopting the structural design described above, when water needs to be drawn, the gate can be opened from top to bottom or a specific gate within a certain water depth range can be opened individually, thereby achieving layered water drawing, which is relatively convenient to operate. Furthermore, by setting the center of the second transmission structure on the rotation axis of the gate, the rotation arm is relatively large and remains essentially constant during gate rotation. This allows the drive device to provide only a small driving force to achieve smooth gate rotation, thereby reducing the operating power and energy consumption of the drive device. The number of drive devices, the first transmission structure, and the second transmission structure can be set according to actual needs; the rotation direction of the gate can also be set according to actual needs, for example, the gate can be set to rotate horizontally or vertically; the so-called transmission connection means that the first transmission structure can transmit its own rotation process to the second transmission structure, causing the second transmission structure to rotate along with the rotation of the first transmission structure.

[0010] Preferably, the first transmission structure and the second transmission structure are respectively provided with transmission teeth, and the first transmission structure and the second transmission structure mesh with each other through the transmission teeth.

[0011] In this technical solution, by adopting the structural design described above, the first transmission structure and the second transmission structure are engaged by transmission teeth. This structural design enables the combined tiered water intake gate provided by this invention to operate more smoothly. The position of the transmission teeth on the first transmission structure can be set according to actual conditions; for example, the transmission teeth can be positioned on the side of the first transmission structure that is away from or close to the gate body.

[0012] Preferably, the first transmission structure and the second transmission structure are connected by a toothed pin drive.

[0013] In this technical solution, by adopting the above-described structural design, the first transmission structure and the second transmission structure are connected by a toothed pin transmission. This structural design enables the combined layered water intake gate provided by the present invention to operate more smoothly.

[0014] Preferably, the combined layered water intake gate has civil engineering structures on both sides, and the civil engineering structures have installation grooves, into which the gate frame can be installed or removed.

[0015] In this technical solution, by adopting the above-described structural design, the installation of the gate assembly can be made more convenient, and when it is necessary to repair or replace some gate assemblies, there is no need to disassemble other gate assemblies, making the operation convenient.

[0016] Preferably, each gate assembly includes at least two gate bodies and at least two gate frames that match the gate bodies, with each gate body rotatably connected to a gate frame, and the gate frames being integrally formed.

[0017] In this technical solution, by adopting the above-described structural design, when installing or repairing the combined layered water intake gate provided by this invention, two or more sets of gate bodies and gate frames can be installed and disassembled simultaneously, which is convenient for operation.

[0018] Preferably, the driving device includes a worm gear reducer, which drives the door to rotate when running and locks the door when the worm gear reducer stops running.

[0019] In this technical solution, by adopting the structural design described above, the drive device is set as a worm gear reducer with a locking function. This structural design allows the gate to be stably held in either the water-blocking or water-releasing position. Regarding the location of the worm gear reducer, it can be arranged according to actual needs; for example, it can be placed inside the gate frame, thereby further reducing the required space, facilitating installation, and preventing the drive device from obstructing water flow in the river channel.

[0020] Preferably, the driving device includes a hydraulic motor with a locking function, which drives the door to rotate when the hydraulic motor is running, and locks the door when the hydraulic motor stops running.

[0021] In this technical solution, by adopting the structural design described above, the drive device is set as a hydraulic motor with a locking function. This structural design allows the gate to be stably held in either the water-blocking or water-releasing position. Regarding the location of the hydraulic motor, it can be arranged according to actual needs; for example, it can be placed inside the gate frame, thereby further reducing the required space, facilitating installation, and preventing the drive device from obstructing water flow in the river channel.

[0022] Preferably, each gate assembly includes at least two drive units, at least two first transmission structures, and at least two second transmission structures.

[0023] In this technical solution, by adopting the structural design described above, the operational stability of the tiered water intake gate can be further improved.

[0024] Preferably, the gate assembly further includes a debris baffle plate, which has a receiving space for accommodating the first transmission structure and the second transmission structure. When the gate rotates, the first transmission structure and the second transmission structure move within the receiving space.

[0025] In this technical solution, by adopting the structural design described above, a debris-blocking plate with accommodating space is installed. This structural design can prevent branches and other floating objects from getting stuck near the second transmission structure, thus avoiding interference with the transmission process of the drive device, the first transmission structure, and the second transmission structure, thereby ensuring the normal operation of the combined tiered water intake gate provided by this invention.

[0026] Preferably, the door body is a rectangular structure, the rotation axis of the door body is located on the axis of symmetry of the door body, and the radius of the second transmission structure is not greater than half of the length and / or width of the door body.

[0027] In this technical solution, by adopting the above-described structural design, the force applied during the rotation of the door can be made more stable, and the dimensions of the second transmission structure can be set according to the actual situation.

[0028] Preferably, the first transmission structure is a circular transmission gear.

[0029] In this technical solution, by adopting the above-described structural design, the second transmission structure is set as a transmission gear, thereby enabling the transmission process to be realized with a relatively simplified structure.

[0030] Preferably, the central angle corresponding to the second transmission structure is greater than or equal to 90°.

[0031] In this technical solution, by adopting the above-described structural design, the central angle corresponding to the second transmission structure is set to be greater than or equal to 90°, which can ensure water intake while setting the central angle corresponding to the second transmission structure according to actual needs.

[0032] Preferably, the gate assembly further includes a limiting structure, which is disposed on the gate body and is used to limit the rotation range of the gate body.

[0033] In this technical solution, by adopting the structural design described above, the rotation of the door can be further controlled through the limiting structure, thereby meeting the control requirements.

[0034] Preferably, the drive device has a waterproof structure.

[0035] In this technical solution, by adopting the structural design described above, the combined layered water intake gate provided by this invention can have better waterproof performance.

[0036] A combined tiered water intake gate includes several gate components located at different heights;

[0037] Each gate assembly includes a gate body, a gate frame, a drive device, a first transmission structure, and a second transmission structure, with the gate body and the gate frame rotatably connected.

[0038] The driving device is fixedly connected to the door body, and the second transmission structure is fixedly connected to the door frame. The second transmission structure is circular or arc-shaped, and the center of the second transmission structure is located on the rotation axis of the door body. The driving device is connected to the first transmission structure and can drive the first transmission structure to rotate. The first transmission structure is connected to the second transmission structure. The driving device drives the first transmission structure and the second transmission structure to move relative to each other, thereby driving the door body to rotate.

[0039] In this technical solution, by adopting the above-described structural design, when water needs to be taken, the gate can be opened from top to bottom or a gate within a certain water depth range can be opened individually, thereby achieving layered water intake, which is relatively convenient to operate. In addition, by setting the center of the second transmission structure on the rotation axis of the gate, the rotation arm is large and basically remains unchanged during the rotation of the gate, so that the drive device only needs to continuously provide a small driving force to achieve smooth rotation of the gate, thereby reducing the operating power and energy consumption of the drive device.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] 1. The combined layered water intake gate provided by the present invention, by setting a driving device, a first transmission structure and a circular or arc-shaped second transmission structure, and setting the center of the second transmission structure on the rotation axis of the gate body, makes the gate body have a large rotational power arm, and the size of the rotational power arm remains relatively stable during the rotation of the gate body, so that the driving device only needs to continuously provide a small driving force to achieve smooth rotation, thereby reducing the operating power of the driving device and reducing energy consumption;

[0042] 2. The combined layered water intake gate provided by this invention has a simple overall structure, low cost, and fast construction and production speed;

[0043] 3. The combined layered water intake gate provided by the present invention can use a smaller driving device, and the driving device can be set inside the gate frame, which is convenient for arrangement and avoids the obstruction of water by placing the driving device directly in the river channel.

[0044] 4. The combined layered water intake gate provided by the present invention detachably connects the gate components and the gate frame, which facilitates installation and maintenance. Attached Figure Description

[0064] Example 1

[0065] like Figures 1 to 3 As shown, this embodiment provides a combined layered water intake gate, including several gate components located at different heights.

[0066] Specifically, each gate assembly includes a gate body 2, a gate frame 1, a drive device 31, a first transmission structure 32, and a second transmission structure 33, with the gate body 2 rotatably connected to the gate frame 1.

[0067] The second transmission structure 33 is arc-shaped and fixedly connected to the door body 2. The center of the second transmission structure 33 is located on the rotation axis of the door body 2. Regarding the specific form of the first transmission structure 32, in this embodiment, the first transmission structure 32 is a transmission gear. The first transmission structure 32 and the second transmission structure 33 are each provided with a plurality of transmission teeth. The first transmission structure 32 and the second transmission structure 33 mesh with each other through the transmission teeth. The first transmission structure 32 is connected to the driving device 31, which can drive the first transmission structure 32 to rotate the second transmission structure 33, thereby causing the door body 2 to rotate.

[0068] Regarding the direction of rotation of door 2, it can be set according to the actual situation. In this embodiment, door 2 is set to rotate in the vertical direction, while in other embodiments, door 2 can be set to rotate in the horizontal direction.

[0069] Regarding the rotation process of the gate 2, the first transmission structure 32 is driven to rotate by the drive device 31. The first transmission structure 32 drives the second transmission structure 33 to rotate through the transmission teeth, thereby causing the gate 2 to rotate with the second transmission structure 33. In actual operation, when water needs to be taken, the gate 2 can be opened from top to bottom or a portion of the gate 2 can be opened individually to take water within a specific water depth range. This structural design allows the gates 2 at different heights to be opened or closed independently, thus enabling the taking of water at a specific depth as needed, making operation convenient. Furthermore, by setting the center of the second transmission structure 33 on the rotation axis of the gate 2, the gate 2 has a large rotational arm, and the size of the rotational arm remains relatively stable during the rotation of the gate 2. This allows the drive device 31 to continuously provide only a small driving force to achieve smooth rotation of the gate 2, thereby reducing the operating power and energy consumption of the drive device 31.

[0070] Furthermore, regarding the connection method between the gate body 2 and the gate frame 1, in this embodiment, an installation groove is opened in the civil structure, and the gate frame 1 of each gate component can be installed into the installation groove and detachably connected to the installation groove. This structural design makes the installation of the gate components more convenient, and when it is necessary to inspect or replace some gate components, it is not necessary to disassemble other gate components, making the operation more convenient.

[0071] Furthermore, the drive device 31 is a worm gear reducer. When the reducer is running, it can drive the door body 2 to rotate. When the reducer stops running, the door body 2 is locked to a certain position through the first transmission structure 32 and the second transmission structure 33. It should be noted that in this embodiment, the drive device 31 is a worm gear reducer. In other embodiments, the drive device 31 can be set to other structures. For example, the drive device 31 can be set to a hydraulic motor with a locking function. When the hydraulic motor is running, the door body 2 rotates relative to the door frame 1. When the hydraulic motor stops running, the door body 2 is locked. Regarding the position of the drive device 31, such as... Figure 3 As shown, in this embodiment, the drive device 31 is arranged inside the gate frame. This structural design makes the combined layered water intake gate provided in this embodiment occupy less space, is easier to arrange, and will not cause water blockage.

[0072] Furthermore, the number of the drive device 31, the first transmission structure 32, and the second transmission structure 33 can be set according to actual needs. In this embodiment, each of the drive device 31, the first transmission structure 32, and the second transmission structure 33 is set to one and arranged on one side of the door. In other embodiments, the drive device 31, the first transmission structure 32, and the second transmission structure 33 can be set to two or more.

[0073] Furthermore, the structure of the first transmission structure 32 can be configured in different forms depending on the actual situation. In this embodiment, the first transmission structure 32 is a transmission gear, which meshes with the second transmission structure 33. The size of the transmission gear varies depending on its position. For example, when the transmission gear is located near the edge of the door body 2, a smaller size is sufficient to mesh with the first transmission structure 32; while when the transmission gear is located near the middle of the door body 2, a larger size transmission gear is required to mesh with the first transmission structure 32.

[0074] Example 2

[0075] like Figure 4 As shown, this embodiment provides a combined tiered water intake gate, which is largely the same as the combined tiered water intake gate in the first embodiment. The difference is that in the first embodiment, the driving device 31, the first transmission structure 32, and the second transmission structure 33 are all configured as one. In this embodiment, the driving device 31, the first transmission structure 32, and the second transmission structure 33 are all configured as two, and a debris baffle 4 is also provided.

[0076] Regarding the specific structure of the debris barrier 4, in this embodiment, a space is provided on the debris barrier 4 to accommodate the first transmission structure 32 and the second transmission structure 33. When the gate body 2 rotates, the first transmission structure 32 and the second transmission structure 33 can move within the space. This structural design can prevent branches and other floating objects from getting stuck near the second transmission structure 33, thus affecting the transmission process of the drive device 31, the first transmission structure 32, and the second transmission structure 33, thereby ensuring the normal operation of the combined tiered water intake gate provided by this invention.

[0077] Regarding the position of the debris barrier 4, it can be set according to actual needs. In this embodiment, the debris barrier 4 is set between the second transmission structure 33 and the door body 2.

[0078] 3rd Embodiment

[0079] like Figures 5 to 6 As shown, this embodiment provides a combined tiered water intake gate, which is largely the same as the combined tiered water intake gate in the first embodiment. The difference is that in the first embodiment, the driving device 31, the first transmission structure 32, and the second transmission structure 33 are located on one side of the gate body, and the driving device 31 is located inside the second transmission structure 32. In this embodiment, the driving device 31, the first transmission structure 32, and the second transmission structure 33 are located in the middle of the gate body, and the driving device 31 is located outside the second transmission structure 32.

[0080] Example 4

[0081] This embodiment provides a combined tiered water intake gate, which is largely the same as the combined tiered water intake gate in the first embodiment. The difference is that in the first embodiment, each gate assembly includes a gate body 2 and a gate frame 1, that is, each gate body 2 is set independently of each other.

[0082] In this embodiment, each gate assembly includes two gate bodies 2 and two gate frames 1 that match the gate bodies 2. The gate bodies 2 and the gate frames 1 are rotatably connected, and each gate frame 1 is integrally formed. This structural design allows multiple sets of gate bodies 2 and gate frames 1 to be installed and disassembled simultaneously during installation and maintenance, making the operation more convenient.

[0083] Example 5

[0084] like Figure 7 As shown, this embodiment provides a combined tiered water intake gate, which is largely the same as the combined tiered water intake gate in the first embodiment. The difference is that in the first embodiment, the second transmission structure 33 is arc-shaped, while in this embodiment, the second transmission structure 33 is circular.

[0085] Example 6

[0086] like Figure 8 As shown, this embodiment provides a combined tiered water intake gate, which is largely the same as the combined tiered water intake gate in the first embodiment. The difference is that in the first embodiment, the rotation axis of the gate body 2 is located on the axis of symmetry of the gate body 2, and the radius of the second transmission structure 33 is half the width of the gate body 2. In this embodiment, however, the radius of the second transmission structure 33 is less than half the width of the gate body 2.

[0087] The specific embodiments of the present invention have been described above. Based on the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of the present invention.
