Description

Technical Field

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

[0002] In water conservancy construction, interception devices are needed to ensure smooth operation in the construction area and prevent water flow from interfering with the project's progress and quality. These devices can effectively cut off or control the direction of water flow. When building dams, it is necessary to cut off the water flow in specific river sections to facilitate subsequent work such as dam construction. Interception devices ensure that the construction site can proceed in a dry and stable environment, guaranteeing the successful construction of water conservancy projects. However, various floating objects often exist in the water flow, and due to the direction of the water flow, these floating objects continuously converge towards the interception area. However, traditional interception devices often only have simple interception structures and cannot effectively clean these floating objects regularly, leading to the continuous accumulation of floating objects. This not only easily causes device blockage but also weakens the interception effect and affects the normal progress of water conservancy construction. Utility Model Content

[0010] According to a preferred embodiment, the bottom of the support frame is provided with multiple sets of cleaning components, and steel ropes are threaded through the cleaning components. Each cleaning component includes a main support frame, which is detachably connected to the support frame. The main support frame has through holes, and the steel ropes are threaded through the through holes. Below the main support frame, multiple sets of cleaning blocks are provided, and the cleaning blocks are rotatably connected to the main support frame.

[0014] The device features a cleaning assembly on one side of the first gate, comprising a cleaning plate and an inclined block on one side of the cleaning plate, which divides the area into collection zones. The triangular structure of the inclined block causes floating debris near the cleaning plate to converge towards both sides of the inclined block, ending up in the collection zone. A collection funnel is installed within the collection zone. Through the spiral water outlet channel at the bottom of the funnel and the fan-shaped design within the outlet sleeve, the water flow generates a vortex as the cleaning plate rises, making it easier for floating debris to be drawn into the collection funnel, thus efficiently separating and collecting the debris from the water flow. This effectively solves the problem of traditional interception devices being easily clogged by floating debris, improving the stability and continuity of the interception device's operation. Simultaneously, it enhances operational efficiency during water conservancy construction, reduces construction delays caused by floating debris interference, and ensures the smooth progress of water conservancy projects.

[0015] The cleaning unit consists of a main support frame, multiple sets of cleaning blocks, and hydraulic rods. The main support frame and the support bracket are detachably connected for easy installation and maintenance. A steel cable is threaded through the cleaning unit, and the multiple sets of cleaning blocks are rotatably connected below the main support frame, forming a cleaning sleeve that holds the steel cable in place via semi-circular grooves. When the steel cable retracts, the sharp-edged cleaning blocks effectively scrape off impurities such as mud and weeds adhering to the cable. The movable triangular structure formed by the hydraulic rods allows the cleaning blocks to adapt to the movement of the steel cable, automatically adjusting the cleaning angle to ensure effective cleaning while preventing excessive wear on the steel cable, extending its service life, reducing cable malfunctions caused by impurity accumulation, and ensuring stable operation of the interception device.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model. Example

[0026] like Figures 1 to 7 As shown, this utility model provides a flow interception device for hydraulic construction, including a main body 11, a first gate 21, and a second gate 22. The main body 11 serves as the foundation component, and a flow channel 12 and a blocking channel 13 are formed on it. The flow channel 12 guides water flow and provides a channel for water flow control of the entire device. The first gate 21 and the second gate 22 are located in the blocking channel 13, and they are in direct contact with the main body 11. The first gate 21 and the second gate 22 can intercept and control the water flow within the blocking channel 13. A support frame 14 is provided above the main body 11, and the support frame 14 stands firmly on the main body 11. A winding structure is installed on its top. The winding structure is connected to the first gate 21 and the second gate 22 by multiple sets of steel ropes. With the help of the winding structure, the raising and lowering of the first gate 21 and the second gate 22 can be controlled to adapt to different water flow conditions. A cleaning component is provided on one side of the first gate 21. The cleaning assembly includes a cleaning plate 31, and a winding structure is also connected to the cleaning plate 31 via a steel cable. An inclined block 32 is installed on one side of the cleaning plate 31, dividing it into two collection zones. When the water flow carries floating debris close to the first gate 21, the inclined block 32 disperses the debris to both sides as the cleaning plate 31 rises, causing it to fall into the collection zones for convenient centralized collection and processing.

[0027] like Figures 2 to 4As shown, in the cleaning assembly of the interception device for hydraulic construction, a plurality of collection funnels 33 are provided on one side of the cleaning plate 31. These collection funnels 33 are located within the collection area divided by the inclined block 32. A slot 34 is provided on the cleaning plate 31, providing a foundation for the installation of subsequent structures. A sliding rod 35 is provided within the slot 34, and a connecting block 36 on one side of the collection funnel 33 is precisely engaged within the slot 34 and simultaneously fitted onto the sliding rod 35. In this way, the collection funnel 33 and the cleaning plate 31 are slidably connected. A spring is also provided between the connecting block 36 and the cleaning plate 31, and the spring is fitted onto the sliding rod 35. Under the impact of the water flow, one side of the collection funnel 33 can contact the inner wall of the flow channel 12, and with the help of the spring's elasticity, its position can be adjusted within a certain range, thereby better adapting to changes in water flow and collecting floating debris.

[0028] The collecting funnel 33 is submerged below the water surface, with a water outlet block 37 at its bottom. The water outlet block 37 contains a spiral-shaped water outlet channel, which serves a unique function. A water outlet sleeve 38 passes through the water outlet block 37 and connects to the collecting funnel 33. One end of the water outlet channel is an inlet located at the bottom of the collecting funnel 33, and the other end is an outlet. When water carrying floating debris enters the collecting funnel 33, some water flows through the bottom inlet into the spiral-shaped water outlet channel. Because the channel is spiral-shaped, the water flow within it creates a special flow effect, which helps to better retain floating debris within the collecting funnel 33.

[0029] The water outlet sleeve 38 at the bottom of the water outlet block 37 has its top as the water outlet. A support frame 39 is installed inside the water outlet sleeve 38, and a bearing is mounted on the support frame 39. A fan blade 41 is also installed inside the water outlet sleeve 38, passing through the bearing, thus allowing the fan blade 41 to be rotatably connected to the support frame 39. When water flows from the water outlet channel through the water outlet sleeve 38, the impact force of the water flow drives the fan blade 41 to rotate. The rotation of the fan blade 41 further promotes water flow, enhancing the collection effect of floating debris, and also helps to more efficiently discharge water from the collection funnel 33.

[0030] The cleaning assembly also includes a collection bag 42, and a fixing frame 43 is provided above the collection funnel 33. The fixing frame 43 and the collection funnel 33 are detachably connected. The collection bag 42 is located within the space enclosed by the collection funnel 33 and the fixing frame 43. The fixing frame 43 is provided with multiple sets of connecting hooks 44, and the collection bag 42 is opened upwards and fitted onto the multiple sets of connecting hooks 44. To keep the collection bag 42 in a stable position in the water, a counterweight ring 45 is also provided at its bottom. When the collection funnel 33 collects floating objects, the floating objects will enter the collection bag 42, thereby achieving centralized collection of floating objects for convenient subsequent cleaning and treatment.

[0031] like Figure 2 , Figure 5 As shown, in the interception device used in water conservancy construction, the bottom of the support frame 14 is equipped with multiple sets of cleaning components, which play an important role in the operation of the entire device. Steel cables pass through the cleaning components, which include a main support 51. The main support 51 and the support frame 14 are detachably connected, allowing for easy removal of the main support 51 from the support frame 14 during subsequent maintenance and repair, greatly facilitating operation. The main support 51 has a through hole through which the steel cable passes. Below the main support 51, multiple sets of cleaning blocks 52 are installed, rotatably connected to the main support 51. Each cleaning block 52 has a semi-circular groove 53. When one side of multiple sets of cleaning blocks 52 contacts each other, they form a cleaning sleeve, within which the steel cable passes. The bottom of the cleaning blocks 52 is sharp, effectively scraping away impurities adhering to the steel cable. Simultaneously, the main support 51 and the cleaning blocks 52 are connected by hydraulic rods, forming a movable triangular structure. When the steel rope moves, this triangular structure can adjust the position and angle of the cleaning block 52 to better adapt to the state of the steel rope.

[0032] like Figure 2 , Figure 6 , Figure 7 As shown, the height of the second gate 22 is greater than the height of the first gate 21, presenting a stepped layout. Multiple sets of partition blocks 15 are arranged within the partition groove 13, dividing the partition groove 13 into two sets of partition slots. The first gate 21 and the second gate 22 respectively engage with their corresponding partition slots. A gap is naturally formed between the first gate 21 and the second gate 22. This gap provides a special guiding and control function for the water flow.

[0033] Multiple sets of limiting blocks 16 are provided on one side of the cleaning plate 31, and limiting grooves 17 are formed on the first gate plate 21 at the positions corresponding to the limiting blocks 16. The limiting blocks 16 are locked in the limiting grooves 17. This arrangement ensures the stability of the cleaning plate 31 during movement and prevents it from shaking randomly. The inclined block 32 has a triangular structure, with its bottom width being greater than its top width. When the water flow carries floating objects close to the cleaning plate 31, this structure can guide the floating objects to converge on both sides of the inclined block 32, improving the collection efficiency of floating objects.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
