Description

Technical Field

[0001] This utility model relates to the field of water conservancy equipment, specifically a pre-tightening device for a stacked beam gate for waterways. Background Technology

[0002] Stacked beam gates, also known as stacked beam sluice gates, are constructed by stacking multiple individual gate panels horizontally within a gate slot to form a planar water-blocking structure. While simple in structure, lightweight, and requiring little lifting force, making them easy to transport, the overall integrity of the water-blocking structure is poor due to the reliance on the weight of the gate panels for sealing. This results in less effective water level-based sealing and slightly higher leakage than steel gates. Therefore, stacked beam gates are best suited for temporary water blocking or maintenance purposes. In practice, workers can use the stacked beam gate to block the water flow, allowing them to perform construction work behind it. However, different waterways have varying flow rates and sediment content, necessitating a more efficient stacked beam gate to facilitate construction work in the direction of water flow throttling. Traditionally, after the construction of stacked beam gates, the interception capacity of the gates in different waterways is inconsistent, resulting in inconsistent flow rates of the intercepted water in different waterways. This causes construction disruptions for workers in the waterways behind the stacked beam gates and fails to meet the interception requirements of different waterways.

[0003] Based on the above problems, it is necessary to set up a pre-tightening device for stacked beam gates in waterways, which can build stacked beam gates to meet different waterway flow problems, so that the stacked beam gates can adapt to the interception requirements in different waterway environments, thereby ensuring that the stacked beam gates have the interception effect that meets the usage requirements and avoiding the drawbacks of poor flow throttling effect. Utility Model Content

[0004] The purpose of this utility model is to provide a pre-tightening device for a stacked beam gate in waterways. It can build stacked beam gates to meet different waterway flow problems, so that the stacked beam gates can adapt to the interception requirements in different waterway environments, thereby ensuring that the stacked beam gates have the interception effect required for use and avoiding the drawbacks of poor flow throttling effect.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] A pre-tightening device for a stacked beam gate in a waterway includes a pre-tightening end and a traction component. Each gate plate is provided with a traction hole, and the traction component is installed through multiple traction holes. The pre-tightening end is fixedly installed on the gate plate at the lowest position, and one end of the traction component is connected to the pre-tightening end, while the other end is connected to the gate plate at the lowest position.

[0007] The pre-tightening end includes a pre-tightening sleeve, which is threadedly fitted onto the gate plate at the lowest position, and the traction member is installed through the pre-tightening sleeve and fixedly connected to the pre-tightening sleeve.

[0008] A pre-tightening spring is fitted on the outside of the pre-tightening sleeve. The upper end of the pre-tightening spring cooperates with a protrusion on the outside of the pre-tightening sleeve, and the lower end is connected to a pressure sensor.

[0009] A fixing ring is provided at the upper end of the traction component, and a traction beam is built on the gate plate at the uppermost position. The fixing ring is fixed through and fixed on the traction beam.

[0010] The traction component is a traction steel cable.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] During setup, this device involves fixing one end of the traction component and then tightening it using the pre-tightening end. This applies a consistent force to the multiple gate plates of the stacked beam gate, resulting in a tighter seal between adjacent gate plates. Furthermore, a pressure sensor is integrated with the pre-tightening end. The pressure sensor's sensitivity coefficient determines the tension of the traction component, allowing for adjustments to the traction force based on the flow rate of different waterways. This ensures that the constructed stacked beam gate meets the waterway's flow control requirements. Attached Figure Description

[0018] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0019] Because the flow velocity and sediment content vary across different waterways, it's crucial to ensure consistent flow control effectiveness when using stacked beam gates to intercept water flow in different waterways. In many cases, after using stacked beam gates to intercept water flow, workers will perform construction operations in the waterway behind the gate. Therefore, the appropriate flow control effect directly impacts the workers' progress. Traditional stacked beam gates do not consider these factors, thus hindering some construction operations.

[0020] To address the above issues, the following structural settings are implemented:

[0021] A pre-tensioning device for a stacked beam gate in a waterway includes a pre-tensioning end 1 and a traction member 2. Each gate plate 3 has a traction hole, and the traction member 2 passes through multiple traction holes. The pre-tensioning end 1 is fixedly mounted on the lowest gate plate 3, and one end of the traction member 2 is connected to the pre-tensioning end 1, while the other end is connected to the lowest gate plate 3. After multiple gate plates 3 are assembled, the traction holes of the multiple gate plates 3 are connected in series using the traction member 2, and the upper end of the traction member 2 is fixed. Next, a pre-tensioning sleeve 4 is rotated relative to the threaded gate plates 3, causing the pre-tensioning sleeve 4 to pull the traction member 2, thereby changing the tension between the multiple gate plates 3. For different waterway environments, the traction member 2 pulls and stretches the multiple gate plates 3, thereby changing the closing force between adjacent gate plates 3 to control different water flows through the stacked beam gate.

[0022] The above structure is further designed and optimized as follows:

[0023] Regarding the pre-tightening method of the pre-tightening end 1, the pre-tightening end 1 includes a pre-tightening sleeve 4, which is threadedly fitted onto the gate plate 3 at the lowest position. The traction member 2 passes through the pre-tightening sleeve 4 and is fixedly connected to it. When adjusting the gate plate, it is necessary to ensure that the pre-tightening end 1 effectively pre-tightens the entire gate plate 3. Therefore, the pre-tightening end 1 is set as the pre-tightening sleeve 4, which is screwed onto the gate plate 3 at the lowest position. When the pre-tightening sleeve 4 rotates, it can move up and down relative to the screwed gate plate 3, thereby pulling and causing the traction member 2 to stretch and contract, thus adjusting the force between the gate plates 3 as a whole.

[0024] A pre-tensioning spring 5 is fitted onto the outer side of the pre-tensioning sleeve 4. The upper end of the pre-tensioning spring 5 engages with a protrusion 6 on the outer side of the pre-tensioning sleeve 4, and the lower end is connected to a pressure sensor 7. Displaying the traction force is the most effective way to demonstrate the pre-tensioning effect, preventing the traction force threshold of the traction component 2 from being reached and avoiding the loss of normal traction function. Simultaneously, it allows for numerical monitoring of different waterway environments, preventing excessive impact on the uppermost gate plate 3 due to varying waterway flow velocities, and facilitating timely adjustment of the traction force of the traction component 2 based on pressure changes.

[0025] A fixing ring 8 is provided at the upper end of the traction component 2, and a traction beam 9 is constructed on the gate plate 3 at the uppermost position. The fixing ring 8 is fixed through and on the traction beam 9 to facilitate the fixing operation of the upper end of the traction component 2. The traction component 2 is a traction steel cable to ensure that the traction component 2 has sufficient traction strength.

[0026] Therefore, a pre-tightening device for a stacked beam gate for waterways can be used to construct stacked beam gates for different waterway flow problems, so that the stacked beam gates can adapt to the interception requirements in different waterway environments, thereby ensuring that the stacked beam gates have the interception effect required for use and avoiding the drawbacks of poor flow throttling effect.
