Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a diversion device for water conservancy engineering construction. Background Technology

[0002] In the field of water conservancy construction, for scenarios such as farmland irrigation canal renovation or small river dredging, the core is to create a waterless or low-water-level working environment for construction within the waterway by blocking or regulating the flow of water, while avoiding water leakage that could cause flooding losses to the surrounding areas.

[0003] In traditional construction, sandbags are often manually stacked to form water-retaining walls. This method is not only time-consuming and labor-intensive, but also prone to leakage due to gaps in the stacking and water flow impact. Based on this, existing technologies have developed interception devices for blocking water bodies. For example, a water-blocking device for hydraulic engineering construction, patent application number 202320821285.X, uses several sets of vertical plates inserted into the bottom of the waterway to form an interception surface to block water flow. However, due to the limitations of its structure in underwater operations, in practical applications, to achieve effective interception, it is often necessary to first shut off the water supply to the waterway, which is not conducive to quickly and reliably achieving the interception function in water-filled construction scenarios. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in related technologies. To this end, this utility model proposes a diversion device for water conservancy engineering construction.

[0005] The technical solution to the technical problem solved by this utility model is as follows: This utility model proposes a diversion device for water conservancy engineering construction, including a mounting frame with a U-shaped structure. Mounting plates are fixed on both sides, and limiting plates are fixedly connected to the front and rear sides of the mounting frame, forming an installation cavity between the two limiting plates. A diversion plate is detachably installed in the installation cavity. A pedal is detachably connected between the two mounting plates and has an inspection port inside. Internally threaded cylinders are pre-embedded on both sides of the waterway. Both mounting plates and the pedal are connected to the internally threaded cylinders by means of a first bolt and positioned in the waterway.

[0006] Preferably, the intercepting plate is composed of several sets of water baffles tightly assembled. The water baffle includes a plate body, and slots and protrusions are provided on both sides of the plate body. The slots and protrusions are distributed in a front-to-back manner. The protrusions achieve telescopic movement by means of a driving part inside the plate body. Adjacent water baffles are staggered and assembled. When the protrusions extend outward, they can be adapted to and inserted into the slots of the adjacent water baffles.

[0007] Preferably, the driving part includes a movable cavity opened in the plate body, a core plate fixed at the center of the movable cavity, and convex plates connected to both sides of the core plate by means of tension springs. The convex plates have a trapezoidal structure, and top plates are respectively provided on the upper and lower sides of the core plate. The two top plates move linearly toward the core plate by means of a transmission member provided in the plate body and abut against the convex plates, pushing the outer side of the convex plates out of the movable cavity.

[0008] Preferably, the transmission component includes a rotatable bidirectional threaded rod placed inside the plate body. The two threaded sections of the bidirectional threaded rod are respectively threaded to the two top plates. The upper end of the bidirectional threaded section passes through the top wall of the plate body and is connected to a lockable and positioning handle. Rotating the handle drives the bidirectional threaded rod to cooperate with the two top plates, and under the constraint of the movable cavity, drives the two top plates to move synchronously and linearly.

[0009] Preferably, the upper part of the plate has two threaded holes, and the two ends of the handle have two through holes. The second bolt passes through the through holes and is threadedly connected to the threaded holes to position the handle in the current position.

[0010] Preferably, the outer wall of the convex plate is provided with a water-stopping rubber pad.

[0011] Preferably, the limiting plate has a U-shaped structure, with two limiting plates covering the two sides and bottom of the intercepting plate respectively.

[0012] Preferably, the mounting frame has two base plates fixed at the bottom, the bottom of the two base plates having a trapezoidal structure and forming a closed cavity with the bottom surface of the waterway.

[0013] Preferably, the front and rear side walls of the plate are provided with reinforcing ribs.

[0014] The above technical solution has the following advantages or beneficial effects: 1. In this utility model, the mounting frame is threadedly connected to the internally threaded cylinder pre-embedded in the waterway via mounting plates on both sides. The mounting frame can be fixed to both sides of the waterway while it is submerged. Then, the intercepting plate is inserted into the mounting cavity to form an intercepting surface, preventing further water flow. In scenarios where prolonged water outages are not advisable, such as in small rivers or agricultural irrigation canals, this significantly reduces other impacts caused by water stoppages.

[0015] 2. In this utility model, the intercepting plate is composed of several sets of water baffles tightly assembled. When a water baffle is damaged, it can be maintained or removed and replaced with the help of the connecting sleeve. It is not necessary to disassemble all the water baffles or take out the entire intercepting plate, which can greatly shorten the maintenance time and effectively reduce the impact of interception interruption caused by maintenance.

[0022] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0024] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] like Figure 1 or Figure 4 As shown in the figure, this embodiment proposes a flow interception device for water conservancy engineering construction, which includes a mounting frame 2, which has a U-shaped structure. Mounting plates 3 are fixedly connected to the top of both sides for establishing a connection with the waterway 1. Limiting plates 4 are fixed to the front and rear sides of the mounting frame 2, and an installation cavity 5 is formed between the two limiting plates 4. A flow interception plate 6 is detachably installed in the installation cavity 5, and appropriate waterproofing measures are taken between the flow interception plate and the two limiting plates 4 to form a flow interception surface to prevent water flow. It also includes a pedal 7, which is detachably connected above the two mounting plates 3. An inspection port 8 is opened inside the pedal 7. Internal threaded cylinders are pre-embedded on both sides of the waterway 1. The two mounting plates 3 and the pedal 7 are threadedly connected to the internal threaded cylinders by means of a first bolt 9 and positioned in the waterway 1.

[0026] In this design, the mounting frame 2 is threadedly connected to the internally threaded cylinder pre-embedded in the waterway 1 via the mounting plates 3 on both sides. This allows the mounting frame 2 to be fixed to both sides of the waterway 1 while the water is still flowing. Then, the intercepting plate 6 is inserted from top to bottom into the mounting cavity 5 formed by the two limiting plates 4, thus creating an intercepting surface to prevent further water flow. This significantly reduces the impact of water outages in scenarios where prolonged water interruption is not advisable, such as in small rivers or localized irrigation canals. The step 7 forms a temporary passageway, serving not only as an operating platform for construction personnel but also providing convenient access for inspection and maintenance of the contact area between the intercepting plate 6 and the mounting frame 2 via its inspection port 8.

[0027] With this modular design, when water flow needs to be restored, only the pedal 7 needs to be removed, and the interceptor plate 6 can be pulled out with the help of external equipment. There is no need to disassemble the whole structure. If the interception area needs to be adjusted, only the interceptor plate 6 of different specifications needs to be replaced.

[0028] refer to Figures 2 to 3In some embodiments, the intercepting plate 6 is composed of several sets of water-blocking plates 61 tightly assembled. Each water-blocking plate 61 includes a plate body with reinforcing ribs on both the front and rear sides. Slots 62 and protruding plates 63 are provided on both the left and right sides of the plate body. Water-stopping rubber pads are provided on the outer walls of the protruding plates 63. The slots 62 and protruding plates 63 are arranged in a front-to-back pattern. The protruding plates 63 can extend and retract using a driving mechanism inside the plate body. Adjacent water-blocking plates 61 are staggered in assembly. When a protruding plate 63 extends outward, it can be fitted and inserted into the slot 62 of the adjacent water-blocking plate 61. The protruding plates 63 of the outermost waterproof plates can abut against the inner side of the mounting frame 2 to enhance the tightness of the connection with the mounting frame 2.

[0029] Further reference Figure 3 The drive unit includes a movable cavity 64 formed within the plate body. A core plate 65 is fixed at the center of the movable cavity 64. Two protruding plates 63, as described above, are connected to both sides of the core plate 65 by means of tension springs 67. The protruding plates 63 have a trapezoidal structure. Top plates 66 are respectively provided on the upper and lower sides of the core plate 65. The two top plates 66 move linearly toward the core plate 65 by means of a transmission component in the plate body and abut against the protruding plates 63 to provide thrust, pushing the outer edges of the protruding plates 63 out of the movable cavity 64. The adjacent baffles 61 are assembled in an interlocking manner, allowing them to be inserted into the slots 62 of each other, forming a convex-concave interlocking connection structure. This not only fixes the relative position of the adjacent baffles 61, preventing them from loosening due to water flow impact, but also further seals the gaps between the baffles 61 and the slots 62 through the tight fit between the protruding plate 63 and the slot 62, reducing the risk of leakage. This interlocking assembly creates two labyrinth-like seals between the adjacent baffles 61, further enhancing the seepage prevention function.

[0030] In some embodiments, an electric push rod can be installed inside the baffle plate 61 as a transmission component. The electric push rod will push the two top plates 66 linearly towards the core plate 65, thereby pushing the protruding plate 63 out of the movable cavity. However, using an electric push rod for long-term operation in water requires frequent maintenance to avoid damage. Based on this, in other embodiments, a mechanical structure can be used to realize the telescopic movement of the protruding plate 63. The transmission component includes a bidirectional threaded rod 68 rotatably placed inside the plate body using upper and lower bearings. The two threaded sections of the bidirectional threaded rod 68 are respectively threaded to the two top plates 66. The upper end of the bidirectional threaded section passes through the top wall of the plate body and is connected to a lockable and positioning handle 69. Rotating the handle 69 drives the bidirectional threaded rod 68 to cooperate with the two top plates 66, and under the constraint of the movable cavity 64, drives the two top plates 66 to move synchronously and linearly.

[0031] In this design, the assembly of a single set of baffles 61 does not require large hoisting equipment. During assembly, they are placed sequentially into the installation space, and the protruding plate 63 can be extended by rotating the handle 69 through the inspection port 8, thereby completing the insertion and fixing with the adjacent baffles 61. When a set of baffles 61 is damaged, the handle 69 is rotated in the opposite direction through the inspection port 8, and the tension spring 67 pulls the protruding plate 63 back, allowing it to be removed and replaced individually from the overall intercepting plate 6. This eliminates the need to disassemble all baffles 61 or remove the entire intercepting plate 6, significantly shortening maintenance time and reducing the impact of interrupted flow due to maintenance.

[0032] Furthermore, two threaded holes 610 are provided on the upper part of the plate, and two through holes 611 are provided at both ends of the handle 69. The second bolt 612 passes through the through holes 611 and is threadedly connected to the threaded holes 610 to position the handle 69 in its current position. The handle 69 is used to control the extension and retraction of the protruding plate 63 of the baffle plate 61. If the handle 69 is loose, the protruding plate 63 may retract, causing water leakage and other problems. In this design, the second bolt 612 is used to lock the handle 69 in its current position, which can resist vibration or external force and prevent the handle 69 from rotating or displacing when not in operation, ensuring the stable operation of the intercepting device. The overall operation is relatively simple, and the handle 69 and the second bolt 612 can be operated directly through the inspection port 8.

[0033] In some embodiments, the limiting plate 4 has a U-shaped structure, with the two limiting plates 4 covering the two sides and bottom of the intercepting plate 6 respectively, and waterproof measures are taken between the limiting plate 4 and the intercepting plate 6. Specifically, underwater adhesive can be used to fill the gap to prevent water from entering through the gap between the limiting plate 4 and the intercepting plate 6.

[0034] In water-related operations, the bottom of waterway 1 often retains debris such as stones and silt. If the mounting frame 2 is directly installed inside waterway 1, the debris can easily accumulate between the bottom of the mounting frame 2 and the bottom surface of waterway 1, preventing them from fitting tightly together and creating gaps that can lead to water leakage. Therefore, in some embodiments, the bottom of the mounting frame is fixed with two base plates 10. The base plates 10 have a trapezoidal bottom structure, which, after installation, can form a closed cavity with the bottom surface of waterway 1 to block water flow at the bottom of the mounting frame 2 and prevent sealing problems caused by debris. Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
