Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, and in particular to a fan-shaped bottom shaft driven gate. Background Technology

[0002] Dams are often set up in reservoirs and rivers to regulate the flow of water and stabilize water level fluctuations.

[0003] Existing dams are typically custom-designed monolithic structures. When river widths vary, each dam usually requires a new design, thus limiting their applicability. Furthermore, monolithic dams lack flexibility in regulating water flow, failing to allow for individual adjustments to flow at specific points along the river, resulting in poor performance. Summary of the Invention

[0004] In view of this, this application provides a fan-shaped bottom shaft driven gate to solve the problems of narrow applicability and poor flexibility in water flow adjustment of existing dams.

[0005] This application provides a fan-shaped bottom-shaft driven gate, including a drive assembly, a dam assembly, a sleeve assembly, and a sidewall disposed along the bank in the direction of water flow. The dam assembly includes N dam faces arranged sequentially along the direction of water flow interception. The sleeve assembly passes through the sidewall and includes N transmission pipes nested layer by layer from the outside to the inside. Each transmission pipe can rotate along the central axis of the sleeve assembly. The two ends of the Nth transmission pipe protrude beyond the two ends of the (N-1)th transmission pipe. The end of the Nth transmission pipe closer to the water flow is connected to the Nth dam face. The end of each transmission pipe away from the water flow is connected to the drive assembly. The drive assembly is used to drive the transmission pipes to rotate, thereby causing the dam face to flip and intercept the water flow. Wherein, N is a positive integer greater than or equal to 2.

[0006] In the above scheme, the drive component is connected to each transmission pipe, and the transmission pipes are connected one-to-one with the dam face. The drive component can individually control the rotation of each transmission pipe, thereby controlling each dam face to cut off the water flow, thus flexibly blocking the water flow to adjust the water flow rate. The number of transmission pipes and dam faces can be flexibly set to adapt to rivers of different widths, improving the applicability of the segmented bottom shaft drive gate.

[0007] In one possible design, the drive assembly includes N drive components, and the N drive components are connected one-to-one with the N transmission pipes.

[0008] In the above scheme, each driving component can drive the transmission pipeline connected to it to rotate independently, thereby flexibly controlling the flip angle of each dam surface and improving the accuracy of water flow regulation when the fan-shaped bottom shaft drive gate is used.

[0009] In one possible design, the drive component is a hydraulic drive mechanism or a motor-gear drive mechanism.

[0010] In the above solutions, hydraulic drive mechanisms and motor gear drive mechanisms are widely used, highly reliable, and can adapt well to harsh working environments.

[0011] In one possible design, the drive unit and the transmission pipe are connected via a gear pair.

[0012] In the above scheme, the gear pair transmission structure has high reliability and high transmission accuracy, which can greatly improve the dam surface overturning accuracy.

[0013] In one possible design, the end of the dam surface is provided with an edge portion, which is sleeved on the outside of the transmission pipe and fixedly disposed relative to the transmission pipe.

[0014] In the above scheme, the edge of the dam surface is fixed to the transmission pipeline, so that the sleeve assembly can be set at the bottom of the waterway to save space.

[0015] In one possible design, the fan-shaped bottom shaft drive gate further includes a sealing element, which is sleeved on the Nth transmission pipe and abuts against the inner wall of the (N-1)th transmission pipe.

[0016] In the above solution, the seal can prevent water from entering through the gaps between the sleeve assemblies, thus improving the service life of the sleeve assemblies. In addition, the seal can also limit the position of each transmission pipe, preventing the inner wall of the thinner transmission pipe from contacting and rubbing against the inner wall of the thicker transmission pipe.

[0017] In one possible design, the seal is a sealing gasket.

[0018] In the above solution, the sealing gasket can further improve the waterproof performance and prevent water from entering the sleeve assembly.

[0019] In one possible design, the sealing gasket is a rubber component.

[0020] In the above solution, the rubber sealing gasket provides better waterproofing to prevent water from entering the casing assembly.

[0021] In one possible design, the seal is a sealed bearing.

[0022] In the above scheme, setting a sealed bearing as a sealing element can provide better support while ensuring waterproof performance.

[0023] In one possible design, the fan-shaped bottom shaft driven gate also includes a support member that is abutted against the bottom of the dam surface.

[0024] In the above scheme, the support components can provide support for the dam surface, thereby ensuring the straightness of each pipe in the casing assembly.

[0068] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0069] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0070] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0071] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0072] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0073] The following describes a specific embodiment of the fan-shaped bottom shaft driven gate provided in the embodiments of this application.

[0074] It should be noted that, for ease of description, the dam surface appearing in some embodiments in the following text is also named: the first dam surface, the second dam surface, and the third dam surface; and the transmission pipeline appearing in some embodiments is also named the first transmission pipeline, the second transmission pipeline, and the third transmission pipeline.

[0075] This application provides a fan-shaped bottom shaft driven gate 100, including a drive assembly 2, a dam body assembly 3, a sleeve assembly 4, and a sidewall 1 set along the water flow direction on the bank; the dam body assembly 3 includes N dam faces 31 arranged sequentially along the direction of cutting off the water flow; the sleeve assembly 4 passes through the sidewall 1, and the sleeve assembly 4 includes N transmission pipes 41 nested layer by layer from the outside to the inside, each transmission pipe 41 can rotate along the central axis of the sleeve assembly 4, the two ends of the Nth transmission pipe 41 protrude beyond the two ends of the (N-1)th transmission pipe 41, the end of the Nth transmission pipe 41 closer to the water flow is connected to the Nth dam face 31, and the end of each transmission pipe 41 away from the water flow is connected to the drive assembly 2, the drive assembly 2 is used to drive the transmission pipe 41 to rotate, thereby causing the dam face 31 to flip to cut off the water flow; where N is a positive integer greater than or equal to 2.

[0076] The fan-shaped bottom shaft driven gate 100 can be installed in water environments such as rivers and reservoirs. The dam face 31 in the fan-shaped bottom shaft driven gate 100 can be flipped from a horizontal angle to an angle perpendicular to the direction of water flow to cut off the water flow.

[0077] Please see Figure 1 The sidewall 1 can be a wall structure that extends along the bank in the direction of water flow, or it can be a riverbank structure. The sidewall 1 is used to isolate the drive assembly 2 from the water. The part where the sidewall 1 connects to the sleeve assembly 4 can be equipped with a rubber sealing sleeve to improve the sealing performance.

[0078] The dam component 3 includes multiple dam faces 31, the number of which can be flexibly set according to the river width. Each dam face 31 can be a flat plate structure, and the widths of the various dam faces 31 can be the same or different. The multiple dam faces 31 are arranged sequentially along the direction of water flow interception; specifically, the multiple dam faces 31 can be arranged perpendicular to the direction of water flow. When the segmented bottom-shaft driven gate 100 is applied in a reservoir environment, the multiple dam faces 31 can also be closely arranged at the reservoir outlet.

[0079] Please see Figure 1The sleeve assembly 4 includes N transmission pipes 41 nested layer by layer from the outside to the inside. Each transmission pipe 41 can rotate freely along the geometric central axis of the sleeve assembly 4. Support structures such as bearings can be installed between the transmission pipes 41 to ensure that each transmission pipe 41 can rotate relative to the others. The transmission pipes 41 are nested layer by layer from the outside to the inside and from thick to thin. In two adjacent transmission pipes 41, the thinner transmission pipe 41 is located inside the thicker transmission pipe 41, and the two ends of the thinner transmission pipe 41 protrude from the two ends of the thicker transmission pipe 41. The end of each transmission pipe 41 away from the water flow is connected to the drive assembly 2, which can drive each transmission pipe 41 to rotate. The end of the transmission pipe 41 closest to the water flow is connected to the dam surface 31. Specifically, the thickest transmission pipe 41 on the outermost side is connected to the dam surface 31 closest to the side wall 1, the second thickest transmission pipe 41 is connected to the dam surface 31 second closest to the side wall 1, and so on. Each transmission pipe 41 from thick to thin is connected to each dam surface 31 set along the side wall 1 towards the water body.

[0080] The drive assembly 2 can be any device or equipment capable of driving the transmission pipeline 41 to rotate, such as a motor gear drive device or a hydraulic drive device. The drive assembly 2 can simultaneously control any one of the dam faces 31 to rotate at any angle, thereby finely adjusting the flow rate. The drive assembly 2 can be connected to the transmission pipeline 41 using a gear meshing or other connection method. Furthermore, because the drive assembly 2 is located on the side of the sidewall 1 away from the water body, it is isolated from the water body, making the segmented bottom shaft drive gate 100 easy to maintain and with a long service life.

[0081] The segmented bottom-shaft driven gate 100 provided in this embodiment has a drive assembly 2 connected to each transmission pipe 41, with each transmission pipe 41 corresponding to a dam surface 31. The drive assembly 2 can individually control the rotation of each transmission pipe 41, thereby controlling each dam surface 31 to cut off the water flow, thus flexibly blocking the water flow to adjust the water flow rate. The number of transmission pipes 41 and dam surfaces 31 can be flexibly set to adapt to rivers of different widths, improving the applicability of the segmented bottom-shaft driven gate 100. Furthermore, there are no easily damaged parts in the river channel, and the power equipment is located on both banks, facilitating maintenance.

[0082] The following are specific examples:

[0083] In this embodiment, the fan-shaped bottom shaft driven gate 100 is installed in a river environment. Please refer to [link / reference]. Figures 2 to 7The dam body component 3 of the fan-shaped bottom shaft driven gate 100 includes a first dam face 32, a second dam face 33, and a third dam face 34. The sleeve component 4 includes a first transmission pipe 42, a second transmission pipe 43, and a third transmission pipe 44. The side wall 1 is located on the bank of a river on one side. The first dam face 32, the second dam face 33, and the third dam face 34 are arranged sequentially along the direction of the side wall 1 pointing towards the river. The first transmission pipe 42, the second transmission pipe 43, and the third transmission pipe 44 are nested layer by layer from the outside to the inside. The first transmission pipe 42 is the thickest and shortest. The second transmission pipe 43 is located inside the first transmission pipe 42 and its two ends protrude from the two ends of the first transmission pipe 42. The third transmission pipe 44 is located inside the second transmission pipe 43 and its two ends protrude from the two ends of the third transmission pipe 44.

[0084] The end of the first transmission pipe 42 furthest from the sidewall 1 is connected to the first dam surface 32. The end of the second transmission pipe 43 furthest from the sidewall 1 extends from the first transmission pipe 42 and connects to the second dam surface 33. The end of the third transmission pipe 44 furthest from the sidewall 1 extends from the second transmission pipe 43 and connects to the third dam surface 34. The ends of each of the first, second, and third transmission pipes furthest from the river are connected to the drive assembly 2. Thus, the drive assembly 2 can drive the movement of each dam surface to cut off the water flow.

[0085] It should be noted that the above embodiments only describe the fan-shaped bottom-shaft driven gate 100 on one side of the river. In some embodiments, the fan-shaped bottom-shaft driven gate 100 can be symmetrically arranged on both banks of the river, and the dam body components 3 of the fan-shaped bottom-shaft driven gate 100 on both sides can be joined in the river to cut off the entire river flow. Compared with the single-sided arrangement, the above-mentioned double-sided arrangement can reduce the length of the sleeve assembly 4 and improve the service life of the fan-shaped bottom-shaft driven gate 100.

[0086] In one embodiment, the drive assembly 2 includes N drive elements 21, and the N drive elements 21 are connected to N transmission pipes 41 in a one-to-one correspondence.

[0087] Please see Figure 1 The drive component 2 includes N independently configured drive components 21, where N is a positive integer greater than or equal to 2. Each drive component 21 can drive the transmission pipe 41 connected to it to rotate independently, thereby flexibly controlling the flip angle of each dam surface 31 and improving the accuracy of the fan-shaped bottom shaft drive gate 100 in regulating water flow.

[0088] In one embodiment, the drive element 21 is a hydraulic drive mechanism or a motor gear drive mechanism.

[0089] The hydraulic drive mechanism can be a rotary hydraulic motor, specifically a radial piston hydraulic motor. The main characteristics of a radial piston hydraulic motor are large displacement and low speed (sometimes only a few revolutions per minute or even a fraction of a revolution per minute), allowing it to be directly connected to the working mechanism without the need for a reduction gear, greatly simplifying the overall mechanism. The motor-gear drive mechanism can include a motor and a gearbox. The motor is connected to the input shaft of the gearbox, and the output shaft of the gearbox is connected to the transmission pipe 41. The hydraulic drive mechanism and motor-gear drive mechanism used in this embodiment are widely applicable, highly reliable, and well-suited to harsh working conditions.

[0090] In one embodiment, the drive element 21 is connected to the transmission pipe 41 via a gear pair.

[0091] A gear pair is a basic transmission mechanism consisting of two meshing gears. Gear pairs have high reliability and high transmission accuracy, which can greatly improve the overturning accuracy of the dam surface.

[0092] In one embodiment, the end of the dam surface 31 is provided with an edge portion 311, which is sleeved on the outside of the transmission pipe 41 and fixedly disposed relative to the transmission pipe 41.

[0093] Please see Figure 2 , Figure 3 and Figure 4 The dam surface 31 can be a square structure with an edge 311 on one side. The edge 311 of the dam surface 31 is fixed to the transmission pipe 41. In this way, the sleeve assembly 4 can be set at the bottom of the waterway, and the dam surface 31 can rotate around the transmission pipe 41 as an axis. When the dam surface 31 is parallel to the direction of water flow, it can lie flat at the bottom of the water flow. When the dam surface 31 is perpendicular to the direction of water flow, it can cut off the water flow.

[0094] In one embodiment, the fan-shaped bottom shaft drive gate 100 further includes a sealing element 5, which is sleeved on the Nth transmission pipe 41 and abuts against the inner wall of the (N-1)th transmission pipe 41.

[0095] Please see Figure 5 , Figure 6 and Figure 7 Multiple seals 5 can be provided, and the size of the seals 5 matches the transmission pipes 41 in the sleeve assembly 4. The seals 5 can be provided at the ends of each transmission pipe 41, thus preventing water from entering along the gaps between the sleeve assemblies 4, improving the service life of the sleeve assembly 4. In addition, the seals 5 can also limit the position of each transmission pipe 41, avoiding contact and friction between the inner walls of the thinner transmission pipe 41 and the thicker transmission pipe 41, thereby improving the overall service life of the fan-shaped bottom shaft drive gate 100.

[0096] In one embodiment, the seal 5 is a sealing gasket, and the sealing gasket is a rubber component.

[0097] The sealing gasket can further improve the waterproof performance and prevent water from entering the sleeve assembly 4. The rubber sealing gasket can provide better waterproof performance to prevent water from entering the sleeve assembly 4.

[0098] In one embodiment, the seal 5 is a sealed bearing.

[0099] Using a sealed bearing as a seal 5 can provide better support while ensuring waterproof performance. Because the sealed bearing has high structural strength, it can provide better support for each transmission pipe 41 and improve the smoothness of each transmission pipe 41 during rotation.

[0100] In one embodiment, the fan-shaped bottom shaft driven gate 100 also includes a support member 6, which is disposed below the dam surface 31.

[0101] Please see Figure 1 Because the transmission pipe 41 is relatively long and the dam assembly 3 is relatively heavy, the dam surface 31 at the end furthest from the sidewall 1 is prone to bending the transmission pipe 41. Therefore, this embodiment provides a support member 6. The support member 6 can be a support structure set at the bottom of the river. The end of the support member 6 near the dam surface 31 can be an arc-shaped surface to better support the dam surface 31. In this embodiment, the support member 6 can provide support for the dam surface 31, thereby ensuring that each pipe in the sleeve assembly 4 remains straight.

[0102] Due to installation errors or wear and tear from long-term use, the junction of two adjacent dam faces 31 of the split-segment bottom-shaft driven gate 100 is prone to leaks due to poor sealing. To address this issue, this application incorporates a sealing structure to improve the sealing performance between adjacent dam faces 31.

[0103] In one embodiment, the fan-shaped bottom shaft driven gate 100 further includes a sealing structure, which comprises two sealing components 7, each of which is disposed on one side of two adjacent dam faces 31 that are close to each other; the sealing component 7 includes:

[0104] The fastener 71 has one end connected to the end of the dam surface 31, and the other end of the fastener 71 has two opposing limiting plates 711 protruding out, forming a limiting space 713 between the two limiting plates 711.

[0105] Deformation seal 72, the deformation seal 72 includes a connecting part 721 that extends into the limiting space 713 and is connected to the fixing member 71, and a deformation part 722 that protrudes from the limiting space 713, the deformation part 722 being provided with a deformation cavity 723;

[0106] Adjusting member 73 is movably disposed on fixing member 71. Adjusting member 73 is connected to the side of connecting part 721 away from deformable part 722. Adjusting member 73 is used to adjust the distance between deformable sealing member 72 and fixing member 71.

[0107] When two adjacent dam surfaces 31 are closed, the deformation seals 72 of each of the two sealing components 7 abut against each other to seal the gap between the two dam surfaces 31.

[0108] The sealing structure can be set between any two adjacent dam surfaces 31 in the fan-shaped bottom shaft drive gate 100. In some embodiments, the fan-shaped bottom shaft drive gate 100 is provided with a sealing structure between two adjacent dam surfaces 31 to improve the overall sealing performance of the fan-shaped bottom shaft drive gate 100.

[0109] Please see Figure 8 , Figure 9 and Figure 10 The fastener 71 can be a long strip structure. It can be fixed to the end of the dam face 31 by riveting, welding, or bolting. The end of the dam face 31 refers to the edge 311 of one of two adjacent dam faces 31 closest to the other. Two opposing limiting plates 711 protrude from the end of the fastener 71 away from the dam face 31. The two limiting plates 711 can be parallel to each other, and the line connecting them is in the same direction as the thickness of the dam face 31, forming a limiting space 713 between them. The length of the fastener 71 and the limiting plates 711 can be the same as the height of the dam face 31, thus ensuring that the fastener 71 and the limiting plates 711 completely cover the entire edge of the dam face 31, guaranteeing the sealing of any position on the edge of the dam face 31.

[0110] The deformation seal 72 is made of an elastic material, such as rubber or other elastic materials. The deformation seal 72 can also be a long strip structure, allowing it to completely cover the entire edge of the dam surface 31. The deformation seal 72 has a connecting portion 721 and a deformation portion 722. The deformation portion 722 can have a circular cross-sectional shape, and its interior can contain a deformation cavity 723 of any shape (e.g., cylindrical). The deformation cavity 723 makes the deformation portion 722 more easily deformable, thus achieving a better sealing effect. The connecting portion 721 can be a flat plate structure, extending into the limiting space 713 and connecting to the fixing member 71. Specifically, the connecting portion 721 can be connected to the fixing member 71 using conventional connection structures such as bolts. The spacing between the two dam faces 31 is set so that when the two dam faces 31 are closed together, the limiting plates 711 of the two dam faces 31 are still a certain distance apart. Since the deformation part 722 protrudes outside the limiting space 713, the deformation part 722 on the deformation sealing part 72 of the two dam faces 31 will abut together to seal the gap between the two dam faces 31, thereby achieving a sealing effect.

[0111] Please see Figure 8 The adjusting member 73 is movably mounted on the fixing member 71. The adjusting member 73 can be a bolt, or it can be screwed onto the fixing member 71. The bolt portion of the adjusting member 73 can pass through the fixing member 71 and connect to the side of the connecting portion 721 away from the deformable portion 722. Thus, by turning the adjusting member 73, the distance between the deformable seal 72 and the fixing member 71 can be adjusted. This arrangement allows for flexible adjustment of the length of the deformable portion 722 protruding from the limiting space 713, thereby adjusting the tightness of the sealing structure. Furthermore, when the spacing at the joints of the dam surface 31 is inconsistent, the position of the deformable seal 72 at that location can be adjusted individually to achieve a better sealing effect.

[0112] In one embodiment, the limiting plate 711 is provided with a strip hole 712, and the sealing assembly 7 further includes a limiting member 75, which is slidably disposed in the strip hole 712 along the line connecting the two sealing assemblies 7, and the limiting member 75 is connected to the connecting part 721.

[0113] Please see Figure 9The limiting member 75 can be a bolt or screw with a rod-like structure. A strip-shaped hole 712 is provided on the limiting plate 711. The limiting member 75 passes through the strip-shaped hole 712 and connects to the connecting part 721. Thus, when adjusting the length of the deformable part 722 protruding from the limiting space 713, the limiting member 75 ensures that the deformable seal 72 moves along the length direction of the strip-shaped hole 712, thereby limiting the movement trajectory of the deformable seal 72. Furthermore, due to the connection between the limiting member 75 and the connecting part 721, the deformable seal 72 can be more securely connected to the fixing member 71, thereby improving the strength and stability of the sealing structure.

[0114] In one embodiment, a plurality of adjustment members 73 are provided, and the plurality of adjustment members 73 are spaced apart along the length direction of the deformation seal 72.

[0115] Please see Figure 10 The multiple adjustment parts 73 can be set to more precisely adjust the length of the deformation part 722 protruding from the limiting space 713 at each position of the deformation seal 72. When the spacing at the joint of the dam surface 31 is inconsistent, the position of the deformation seal 72 at that location can be adjusted individually to achieve a better sealing effect.

[0116] In one embodiment, a contact plate 74 is provided at the end of the adjusting member 73 that contacts the deformation seal 72. (See also...) Figure 10 In this embodiment, the point contact between the original adjusting member 73 and the deformation seal 72 is transformed into a surface contact by setting the contact plate 74, which makes the force on the deformation seal 72 more balanced. The larger contact surface between the contact plate 74 and the deformation seal 72 also helps to improve the connection stability between the contact plate 74 and the deformation seal 72.

[0117] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
