Description

Technical Field

[0001] This utility model relates to the field of diversion device technology, and in particular to a diversion device for a gate station forebay. Background Technology

[0002] Flow guiding devices are an important technology in hydraulic engineering, hydraulic structures, and fluid control. They are mainly used to improve flow patterns, reduce turbulence, prevent siltation, optimize fluid distribution, and improve the operational efficiency of hydraulic facilities. In hydraulic engineering projects such as sluice gates, pumping stations, canals, and reservoirs, flow guiding devices, through guide walls, guide piles, and guide plates, guide water flow to a smooth transition, reduce hydraulic losses, and avoid localized scouring or vortex generation, thereby improving the safety and durability of the project.

[0003] Chinese Patent Publication No. CN117513230A discloses a flow guiding device for a pump station forebay, including a track beam fixed between two side walls of the forebay. The track beam has a U-shaped cross-section with the opening facing upwards. The bottom of the track beam has a through groove. Several sliding components with positioning mechanisms are slidably connected inside the track beam. A connecting rod is fixedly connected to the bottom of each sliding component. The bottom of the connecting rod passes through the through groove and is connected to a flow guiding pile.

[0004] In this existing design, although the position of the guide piles can be changed by setting an overhead track beam in the forebay of the pump station, and the arrangement spacing of the guide piles can be adjusted according to the vortex situation in the forebay during actual operation under different operating conditions of the pump station, so as to improve the flow state in the forebay and keep the flow state in the forebay optimal under different operating conditions, the position of the guide piles can be adjusted according to the operating conditions. However, the overall height of the guide piles is fixed. The water level in the forebay fluctuates due to the season, rainfall or pump station start-up and shutdown. The guide piles with a fixed height may be submerged too deeply, resulting in increased resistance, or exposed too much, resulting in insufficient diversion, thus affecting the diversion efficiency.

[0005] Therefore, a flow diversion device for the forebay of the sluice gate is designed to solve the above problems. Utility Model Content

[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Example 1

[0029] In the existing technology, the existing pump station forebay diversion device includes a track beam fixed between the two side walls of the forebay. The track beam has a U-shaped cross-section with an upward opening. The bottom of the track beam has a through groove. Several sliding components with positioning mechanisms are slidably connected inside the track beam. A connecting rod is fixedly connected to the bottom of the sliding component. The bottom of the connecting rod passes through the through groove and is connected to a diversion pile. This pump station forebay diversion device can change the position of the diversion pile by setting an overhead track beam in the pump station forebay. According to the vortex situation in the forebay during actual operation under different operating conditions of the pump station, the arrangement spacing of the diversion piles can be adjusted to improve the flow state in the forebay, so that the flow state in the forebay can always remain optimal under different operating conditions.

[0030] This application incorporates the aforementioned prior art, such as Figures 1 to 6 As shown, this utility model provides a technical solution: a sluice gate forebay diversion device, including a diversion pile 2 fixed inside the forebay 1, a sleeve 3 fixedly installed inside the diversion pile 2, a limiting groove 4 opened on the top surface of the diversion pile 2, a limiting rod 5 slidably connected inside the limiting groove 4, a connecting block 6 fixedly installed on the top of the limiting rod 5, an extension rod 7 inserted inside the connecting block 6, a locking block 8 fixedly installed on the surface of the extension rod 7, a rotating wheel 9 fixedly installed on the top of the extension rod 7, and a threaded groove 10 opened on the surface of the extension rod 7.

[0031] In this implementation scheme: an adjustable-height guide pile 2 is provided. By inserting a height-adjustable extension rod 7 into the guide pile 2, the overall height of the guide pile 2 can be adjusted. The extension rod 7 and the guide pile 2 are connected by a threaded groove 10 and a sleeve 3 that meshes with it. Simply rotating the wheel 9 will drive the extension rod 7 to rotate within the connecting block 6. When the extension rod 7 rotates, since the sleeve 3 has a thread that meshes with the threaded groove 10, the extension rod 7 can be raised and lowered within the guide pile 2. When the extension rod 7 is raised and lowered, the locking block 8 installed on its surface can abut against the connecting block 6, thereby driving the connecting block 6 to move. The connecting block 6 drives the limiting block to extend out from the limiting groove 4, thereby adjusting the height of the guide pile 2. This facilitates the rotation of the extension rod 7 by rotating the wheel 9, thereby raising and lowering the extension rod 7. The limiting groove 4 and the limiting rod 5 are also provided to improve the stability of the extension rod 7 during movement.

[0032] Combining the above solutions:

[0033] Furthermore:

[0034] like Figure 1 As shown;

[0035] In order to ensure uniform water flow, in an optional embodiment, there are several sets of guide piles 2, which are arranged in a trapezoidal array inside the forebay 1.

[0036] In this embodiment, after the water flows through the guide pile 2, it branches and diffuses. After the water flows through the branch and diffuses, it continues to branch and diffuse after encountering the next guide pile 2. In this way, the water flows through the branch and diffuses at each level, so that the water flows evenly in the forebay 1, eliminating any possible eddies or other undesirable flow patterns.

[0037] Combining the above solutions:

[0038] Furthermore:

[0039] like Figure 3 As shown;

[0040] In order to ensure that the bottom surface of the connecting block 6 is subjected to uniform force, in an optional embodiment, there are four sets of limiting grooves 4, which are distributed in a circular array on the top surface of the guide pile 2.

[0041] In this embodiment, there are four sets of limiting grooves 4, which are arranged in a circular array on the top surface of the guide pile 2. Four sets of limiting rods 5 slide in the four sets of limiting grooves 4 respectively. Connecting blocks 6 are installed at the top of the four sets of limiting rods 5, which can make the bottom surface of the connecting block 6 uniformly stressed and improve the support effect of the limiting rods 5.

[0042] Combining the above solutions:

[0043] Furthermore:

[0044] like Figures 2 to 6 As shown;

[0045] In an optional embodiment, in order for the extension rod 7 to drive the connecting block 6 to rise and fall, the extension rod 7 and the connecting block 6 are rotatably connected, and the extension rod 7 is inserted into the sleeve 3.

[0046] In this embodiment: when the rotating wheel 9 is rotated, the rotating wheel 9 drives the extension rod 7 to rotate, and the extension rod 7 then moves inside the guide pile 2. The extension rod 7 and the connecting block 6 are rotatably connected, so that when the extension rod 7 moves, it drives the connecting block 6 to rise and fall. The extension rod 7 is inserted into the inside of the sleeve 3, which facilitates the meshing and transmission between the threaded groove 10 and the sleeve 3.

[0047] Combining the above solutions:

[0048] Furthermore:

[0049] like Figures 2 to 6 As shown;

[0050] In an optional embodiment, to enable the extension rod 7 to move up and down within the guide pile 2, the sleeve 3 is threaded inside, and the thread engages with the threaded groove 10 on the surface of the extension rod 7.

[0051] In this embodiment: the sleeve 3 has a thread inside, and the thread and the threaded groove 10 on the surface of the extension rod 7 are engaged. Since the extension rod 7 is inserted into the sleeve 3, when the extension rod 7 rotates, the threaded groove 10 on its surface can engage with the thread inside the sleeve 3 to drive the extension rod 7 to rise and fall in the guide pile 2.

[0052] Combining the above solutions:

[0053] Furthermore:

[0054] like Figures 2 to 6 As shown;

[0055] In an optional embodiment, to secure the connecting block 6 to the top of the extension rod 7, there are two sets of locking blocks 8, both sets of which are secured to the top of the extension rod 7.

[0056] In this embodiment, there are two sets of locking blocks 8. Both sets of locking blocks 8 are fixed to the top of the extension rod 7, and the connecting block 6 can be fixed inside the two sets of locking blocks 8, thereby fixing the connecting block 6 to the top of the extension rod 7.

[0057] Combining the above solutions:

[0058] Furthermore:

[0059] like Figures 2 to 6 As shown;

[0060] In order to enable the extension rod 7 to move and drive the connecting block 6 to rise and fall synchronously, in an optional embodiment, one set of locking blocks 8 is attached to the top surface of the connecting block 6, and another set of locking blocks 8 is attached to the bottom surface of the connecting block 6.

[0061] In this embodiment: one set of locking blocks 8 and the top surface of the connecting block 6 are attached, and another set of locking blocks 8 and the bottom surface of the connecting block 6 are attached. When the extension rod 7 is raised or lowered, it can drive the two sets of locking blocks 8 on its surface to move. Since the two sets of locking blocks 8 fix the connecting block 6 on the surface of the extension rod 7, the movement of the extension rod 7 can drive the connecting block 6 to rise and fall synchronously.

[0062] Combining the above solutions:

[0063] Furthermore:

[0064] like Figure 2 , Figure 4 and Figure 5 As shown;

[0065] To prevent sediment from entering, in an optional embodiment, a corrugated pipe 11 is fixedly installed on the top surface of the guide pile 2, the bottom of the corrugated pipe 11 is fixedly connected to the top surface of the guide pile 2, and the top of the corrugated pipe 11 is fixedly connected to the bottom surface of the connecting block 6.

[0066] In this embodiment, a corrugated pipe 11 is provided between the limiting rods 5. The two ends of the corrugated pipe 11 are connected to the connecting block 6 and the guide pile 2 respectively. It extends and retracts with the lifting and lowering of the extension rod 7. To a certain extent, it can prevent mud and sand from entering the gap between the extension rod 7 and the guide pile 2, avoid mud and sand from affecting the normal use of the threaded groove 10, and reduce maintenance requirements.

[0067] Combining the above solutions:

[0068] Furthermore:

[0069] like Figure 2 , Figure 4 and Figure 5 As shown;

[0070] To improve practicality, in an optional embodiment, there are four sets of bellows 11, which are respectively fixed between four sets of limiting rods 5.

[0071] In this embodiment, there are four sets of corrugated pipes 11, which are fixed between four sets of limiting rods 5, which can prevent mud and sand from entering the guide pile 2 to a certain extent.

[0072] Working principle: When adjusting the height of the guide pile 2, simply rotate the wheel 9 manually. The wheel 9 will drive the extension rod 7 to rotate. Since the extension rod 7 is inserted inside the sleeve 3 and the sleeve 3 is fixed inside the guide pile 2, the extension rod 7 can rotate inside the sleeve 3. Since the sleeve 3 has a thread that meshes with the threaded groove 10 on the surface of the extension rod 7, the extension rod 7 can move while rotating inside the sleeve 3. When the extension rod 7 is raised or lowered, the locking block 8 on its surface clamps the connecting block 6 on the surface of the extension rod 7. Therefore, the extension rod 7 can drive the connecting block 6 to move. At the same time, the connecting block 6 drives the limiting rod 5 to extend out of the limiting groove 4. When the connecting block 6 moves, since the top end of the corrugated pipe 11 is connected to the bottom surface of the connecting block 6 and the bottom end of the corrugated pipe 11 is connected to the top surface of the guide pile 2, the corrugated pipe 11 extends and retracts under the drive of the connecting block 6 until the guide pile 2 is adjusted to a suitable height. Then, stop rotating the wheel 9.

[0073] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
