Description

Technical Field

[0001] This invention relates to the field of stratified water intake gate technology, and in particular to a rotary stratified water intake gate that does not require an underwater power unit. Background Technology

[0002] Currently, the conventional stratified water intake design usually adopts a planar stacked beam sliding gate. This design is simple, but it has some problems, such as the need to frequently operate the gate opening and closing equipment to remove the gate from the orifice. When there are many water intake orifices, this problem will be more serious.

[0003] To address the above issues, the existing solutions mainly include:

[0004] (1) Conventional solution. The core technical solution of using planar stacked beam sliding gate is to divide each gate into several movable units (single stacked gates) in the vertical direction, and reduce (open) or increase (close) the single stacked gates according to the water level fluctuation.

[0005] (2) New technical solutions - underwater power supply devices. In recent years, various new tiered water intake gate solutions have been continuously disclosed. The core content of most new technical solutions is to improve the single-layer gate structure of conventional stacked beam tiered water intake gates into an integrated device with independent opening and closing structures and underwater operating equipment. For example, CN117026906A is a tiered water intake gate, and CN116446357A is a high-efficiency, energy-saving and easy-to-maintain tiered water intake equipment.

[0006] While existing technologies have addressed some of the drawbacks of conventional tiered intake gates requiring frequent opening and closing, they have also presented new challenges in design and manufacturing. Besides the relatively complex gate leaf structure and high precision requirements of the transmission mechanism, underwater power equipment and underwater power supply are also needed. This not only increases the complexity and cost of the equipment but also raises the risk of system failure.

[0007] Therefore, how to design a stratified water intake scheme that can meet ecological and environmental protection requirements, reduce the frequency of operation, not significantly change the existing conventional hydraulic structure, and eliminate the need for underwater power supply is an urgent problem to be solved. Summary of the Invention

[0008] The present invention provides a rotary tiered water intake gate that does not require an underwater power unit, aiming to solve the shortcomings of conventional tiered water intake stacked beam gate schemes that require frequent opening and closing, as well as the shortcomings of existing schemes that require power equipment and underwater power supply devices.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] A rotary tiered intake gate without underwater power unit includes multi-layered rotary intake gates, columns, and operating components;

[0011] The rotary intake gate includes an arc-shaped gate leaf that rotates in the horizontal plane. The arc-shaped gate leaf is connected to a set of support arms, and the rear outer wall of the end of the support arm is provided with support arm teeth.

[0012] The end of the outrigger is fitted onto the column via a bearing;

[0013] The operating components include a water power mechanism, which is connected to the operating column for lifting and rotating. A set of gears is installed on the operating column, and the gears are arranged one-to-one with the multi-layered rotating water intake gates. The gears are arranged in the same direction on the operating column.

[0014] When the support arm teeth of the rotary intake gate in one layer mesh with the corresponding gear in that layer, the support arm teeth of the rotary intake gates in other layers do not mesh with the gear.

[0015] In the aforementioned rotary stratified water intake gate that does not require an underwater power unit, a bottom water seal is provided at the bottom of the arc-shaped gate leaf.

[0016] In the aforementioned rotary stratified water intake gate that does not require an underwater power unit, a simply supported wheel is provided at the bottom of the arc-shaped gate leaf.

[0017] In the aforementioned rotary stratified water intake gate that does not require an underwater power unit, a single-sided side water seal is provided on the outer side of the arc-shaped gate leaf.

[0018] In the aforementioned rotary stratified water intake gate that does not require an underwater power unit, the middle part of the arc-shaped gate leaf is connected to the support arm.

[0019] In the aforementioned rotary stratified water intake gate that does not require an underwater power unit, the uprights and operating uprights are arranged in parallel directions; the support arm is arranged perpendicular to the uprights.

[0020] An operation method for the aforementioned rotary layered water intake gate without underwater power unit involves raising and lowering the operating column via a hydrodynamic mechanism to engage the support arm teeth on the rear side of the arc-shaped gate leaf with its corresponding gear. Then, the operating column is rotated via the hydrodynamic mechanism, and the gear and support arm teeth drive the arc-shaped gate leaf of that layer to open or close.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] When implementing stratified water intake, this invention avoids the problem of frequent opening and closing required by conventional stratified water intake stacked beam gate schemes, and also eliminates the need for underwater opening and closing power equipment and underwater power supply devices.

[0023] Compared to existing stratified water intake equipment that requires underwater power supply, the present invention is easier to maintain, reducing maintenance frequency and cost. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] An embodiment of a rotary tiered water intake gate that does not require an underwater power unit is described below. Figure 1-6 As shown, it includes a multi-layered rotary intake gate, columns, and operating components;

[0037] The rotary water intake gate includes an arc-shaped gate leaf 2 that rotates in the horizontal plane. The arc-shaped gate leaf 2 is connected to a set of support arms 1. The rear outer wall of the support arm end 101 of the support arm 1 is provided with support arm teeth 102.

[0038] The end arm 101 is mounted on the column 4 via upper and lower bearings;

[0039] The operating components include a water-powered mechanism, which is connected to the operating column 3. A set of gears 301 is installed on the operating column 3, and the gears 301 are configured one-to-one with the multi-layered rotary water intake gate. The water-powered mechanism enables the lifting and rotation of the operating column 3.

[0040] It should be noted that the water propulsion mechanism adopts existing technology, namely a device or equipment that can linearly move and rotate the rod (column 3). For example, the water propulsion mechanism is implemented by having a lifting lug and bearing on the inner side of the top of column 3. The lifting lug is connected to the opening and closing equipment (such as a winch-type gate opener or a hydraulic gate opener) and the gate opener realizes vertical movement. The outer side of the top of column 3 has a gear ring structure, which is connected to four three-in-one reducers (reducer, motor, and brake) evenly distributed around the circumference. The three-in-one reducers drive the circumferential movement of column 3.

[0041] When the support arm teeth 102 of the rotary water intake gate of one layer meshes with the corresponding gear 301 of that layer, the support arm teeth 102 of the rotary water intake gates of other layers do not mesh with the gear 301.

[0042] The gears 301 are set in the same direction on the operating column 3, which means that all gears 301 are aligned in the vertical direction, so as to ensure that there is no collision between the gears 301 and the support arm teeth 102 when the operating column 3 is raised or lowered.

[0043] A bottom water seal 202 is provided at the bottom of the arc-shaped door leaf 2.

[0044] The bottom of the arc-shaped door leaf 2 is provided with a simple support wheel 203.

[0045] A single-sided water seal 201 is provided on the outer side of the arc-shaped door leaf 2.

[0046] The middle part of the arc-shaped door leaf 2 is connected to the support arm 1, which facilitates the control of the arc-shaped door leaf 2 through the support arm 1.

[0047] The uprights 4 and the operating uprights 3 are arranged in parallel directions; the support arm 1 is arranged perpendicular to the uprights 4.

[0048] The further features and functions of the above implementation structure are as follows:

[0049] In this scheme, an arc-shaped gate leaf 2 is used to replace the planar gate. Compared with the current layered water intake technology scheme which is basically a planar gate, the gate leaf structure of this scheme adopts an arc-shaped gate. Compared with the conventional arc-shaped gate, the arc-shaped gate of this scheme has the following characteristics: (1) The rotation surface of this arc gate is a horizontal plane (arc-shaped gate leaf 2), which is not the vertical plane of the conventional arc gate. (2) This arc gate has only one set of support arms 1 (two in a set) in the middle position of the vertical direction of the gate, while the conventional arc gate has two sets of support arms symmetrically distributed at both ends of the gate leaf with the center line as the center line. (3) Each stack (layer) of gate leaf is provided with a bottom water seal 202 at the bottom, and only one side is provided with a single-sided side water seal 201 on one side. The other side is provided with a gate slot embedded water seal 5 on the gate slot structure. (4) Each stack of gate is provided with a simple support wheel 203 at the bottom to reduce the resistance when the single stack of arc gate rotates.

[0050] The column and operating components are both located on the downstream side of the gate. The column 4 and the end of the support arm 101 are connected to the upper and lower sections of the column 4 by upper and lower bearings respectively, and support the rotation of the arc gate.

[0051] The end of the support arm 101 has a flange-like structure, with a gear-like support arm tooth 102 on the downstream side of the flange. This design reduces the frequency of gate operation, improves work efficiency, and eliminates the need for underwater opening and closing power equipment and underwater power supply devices, thereby reducing equipment complexity and cost, and lowering the risk of system failure.

[0052] The hydrodynamic mechanism, employing existing technology, enables the vertical movement and rotation of the operating column 3: gear 301 engages with the support arm gear 102. The gears 301 are not evenly spaced according to the gate spacing; when one set of gears 301 meshes with its corresponding support arm gear 102, the other gears 301 are in a non-meshing state. The operating column 3 is driven to rotate by the hydrodynamic mechanism on the top platform of the inlet, thereby controlling the opening and closing of the arc-shaped gate leaf 2. By moving the operating column 3 vertically to operate other arc-shaped gates, the opening and closing of gates at different heights can be achieved, thus enabling the generation of electricity from surface water at different depths.

[0053] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
