Description

Technical Field

[0001] This utility model belongs to the technical field of hydraulic gate equipment, specifically relating to a dual-power hydraulic gate opening and closing structure. Background Technology

[0002] Gates are a crucial component of water conservancy projects, and their operational reliability directly impacts the overall operation and safety of the project. Traditional hydraulic gates typically utilize a single hoisting device as the power source. Specifically, when the hoist receives a command, it uses power to open and close the gate, thus controlling its operation. However, if this sole hoisting device malfunctions, the gate cannot open or close properly until the fault is resolved. This not only severely impacts the regulation of the water conservancy project but also potentially leads to safety accidents.

[0003] Therefore, there is an urgent need for a more reliable dual-power hydraulic gate opening and closing structure. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a dual-power hydraulic gate opening and closing structure, which solves the problems of single power source and low reliability of the existing gate opening and closing structure.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a dual-power hydraulic gate opening and closing structure, including a linkage shaft and two sets of power drive modules;

[0006] Each of the power drive modules includes an electric motor, a reducer, and a clutch;

[0007] The output shaft of the motor is mechanically connected to the input shaft of the reducer, the output shaft of the reducer is mechanically connected to the driving end of the clutch, the driven end of the clutch is mechanically connected to one end of the linkage shaft, and the driven ends of the clutches in the two sets of power drive modules are respectively mechanically connected to both ends of the linkage shaft; and when the linkage shaft rotates, it can drive the gate to open and close through the opening and closing module.

[0008] Optionally, the clutch includes an electromagnetic coil, a driving plate, and a driven plate;

[0009] When the electromagnetic coil is energized, the driving disc can engage with the driven disc, and the power of the motor can be transmitted to the reducer through the clutch; when the electromagnetic coil is de-energized, the driving disc can disengage from the driven disc to cut off the power transmission between the motor and the reducer.

[0010] Optionally, the opening and closing module includes a drum mechanically connected to the linkage shaft and a steel wire rope wound on the drum. The linkage shaft is mechanically connected to the drum, one end of the steel wire rope is connected to the drum, and the other end of the steel wire rope is connected to the gate.

[0011] Optionally, the surface of the drum is provided with a helical rope groove, the pitch of which matches the diameter of the wire rope.

[0012] Optionally, the output shaft of the motor and the input shaft of the reducer, as well as the output shaft of the reducer and the driving end of the clutch, are connected by couplings.

[0013] Optionally, the driven end of the clutch is connected to the linkage shaft via a spline.

[0014] Optionally, the reducer is a multi-stage gear reducer.

[0015] Optionally, a master controller electrically connected to the two sets of power drive modules may also be included.

[0016] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: In this technical solution, there are two sets of power drive modules, one of which meets the daily operation requirements of the gate, and the other serves as a backup power system. When the power drive module that meets the daily operation requirements of the gate fails, the other power drive module can be activated in time, thereby improving the reliability of the gate operation.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] It should be noted that if directional indicators (such as up, down, bottom, top, etc.) are involved in this embodiment, these directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly. The terms "first" and "second" 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. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. Unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0022] like Figure 1 As shown, a dual-power hydraulic gate opening and closing structure includes a linkage shaft 1 and two sets of power drive modules. Each power drive module includes a motor 2, a reducer 3, and a clutch 4. The output shaft of the motor 2 is mechanically connected to the input shaft of the reducer 3, and the output shaft of the reducer 3 is mechanically connected to the driving end of the clutch 4. The driven end of the clutch 4 is mechanically connected to one end of the linkage shaft 1. Furthermore, the driven ends of the clutches 4 in both power drive modules are mechanically connected to both ends of the linkage shaft 1. Mechanical transmission connection refers to a connection method that uses existing mechanical components to transmit power from one shaft to another, including but not limited to one or more of gear transmission, belt transmission, chain transmission, coupling connection, worm gear transmission, and helical rotation connection. When the linkage shaft 1 rotates, it can drive the gate 5 to open and close via the opening and closing modules. That is, when one set of power drive modules malfunctions, the clutch 4 can actively or passively disconnect the power transmission between that power drive module and the linkage shaft 1. The other power drive module can actively activate clutch 4 within it, allowing the motor 2 to transmit power to the linkage shaft 1 via reducer 3 and clutch 4. This enables the linkage shaft 1 to control the opening and closing of the gate 5 through the opening and closing module. In this technical solution, one power drive module meets the daily operating requirements of the gate 5, while the other serves as a backup power system. When the power drive module meeting the daily operating requirements of the gate 5 fails, the other power drive module can be activated promptly, thereby improving the reliability of the gate 5's operation.

[0023] It should be noted that the clutch 4 in this technical solution is existing technology. The clutch 4 in this technical solution can be an electrically engaged electromagnetic friction clutch 4, meaning that the clutch 4 includes an electromagnetic coil, a driving plate, and a driven plate. When the electromagnetic coil is energized, the driving plate can engage with the driven plate, and the power of the motor 2 can be transmitted to the reducer 3 through the clutch 4; and when the electromagnetic coil is de-energized, the driving plate can disengage from the driven plate to cut off the power transmission between the motor 2 and the reducer 3. Therefore, when the power drive module that meets the daily operating requirements of the gate 5 malfunctions, the power transmission between the power drive module and the linkage shaft 1 can be quickly disconnected by cutting off the power supply to the power drive module, thus avoiding affecting the working status of another set of power drive modules.

[0024] Furthermore, such as Figure 1 As shown, the opening and closing module described above includes a drum 6 mechanically connected to the linkage shaft 1 and a wire rope 7 wound on the drum 6. The linkage shaft 1 is mechanically connected to the drum 6, one end of the wire rope 7 is connected to the drum 6, and the other end of the wire rope 7 is connected to the gate 5. When the power drive module drives the linkage shaft 1 to rotate, the drum 6 can also rotate accordingly, and the rotation of the drum 6 can drive the gate 5 to achieve the opening and closing action. It should be noted that the surface of the drum 6 is provided with a spiral rope groove (not shown in the figure), and the pitch of the spiral rope groove matches the diameter of the wire rope 7 to guide the wire rope 7 to be wound orderly on the drum 6.

[0025] In this embodiment, the output shaft of the motor 2 is connected to the input shaft of the reducer 3, and the output shaft of the reducer 3 is connected to the driving end of the clutch 4 via couplings. This is to compensate for installation errors among the motor 2, clutch 4, and reducer 3, ensuring the stability of power transmission. Simultaneously, the output shaft of the clutch 4 is connected to the linkage shaft 1 via a spline. The spline is a prior art technology, and its toothed structure allows for the transmission of a large torque between the driven end of the clutch 4 and the linkage shaft 1 with high efficiency. Due to the tight meshing of the spline teeth, energy loss is effectively reduced during power transmission, ensuring that power is stably and efficiently transmitted from the driven end of the clutch 4 to the linkage shaft 1, thereby driving the drum 6. Furthermore, in this technical solution, the reducer 3 is a multi-stage gear reducer 3. The multi-stage gear reducer 3 provides a precise reduction ratio, accurately converting the high-speed rotation of the motor 2 into a low-speed rotation suitable for the opening and closing of the gate 5. This facilitates precise control of the opening and closing speed of the gate 5, meeting the stringent requirements for the gate 5's operating speed in different scenarios. Meanwhile, the multi-stage gear reducer 3 can amplify torque while reducing speed, providing sufficient power to the linkage shaft 1 and ensuring that the gate 5 can open and close smoothly and reliably.

[0026] It should be noted that in this technical solution, a dual-power hydraulic gate opening and closing structure also includes a master controller electrically connected to the two sets of power drive modules. The master controller is existing technology and supports remote control functionality, allowing operators to control and monitor the power drive modules remotely via network or other communication methods. Furthermore, when one set of power drive modules fails, the other backup power drive module can be promptly switched to control the opening and closing operation of the gate 5.

[0027] Working principle: When one of the power drive modules malfunctions, the clutch 4 in that power drive module can passively disconnect the power transmission from the linkage shaft 1. Meanwhile, the other power drive module can promptly activate the clutch 4, so that the motor 2 in it can transmit power to the linkage shaft 1 through the reducer 3 and the clutch 4, enabling the linkage shaft 1 to control the opening and closing of the gate 5 through the opening and closing module.

[0028] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
