Description

A kind of intercepting device for water conservancy construction

Technical Field

The utility model relates to the technical field of water conservancy construction, in particular to a flow intercepting device for water conservancy construction.

Background Art

The intercepting device is a temporary retaining structure built during the construction of water conservancy projects to build permanent water conservancy facilities. Its function is to prevent water and soil from entering the construction site of the building so that drainage can be drained inside the intercepting device, foundation pits can be excavated, and buildings can be constructed.

A Chinese utility model patent with announcement number CN220538576U discloses a shut-off device for water conservancy and hydropower construction. A valve seat is provided to fix and support the valve body. The trapezoidal valve seat makes the bottom of the device more stable. The valve seat is integrated for easy installation. The water flow of water conservancy and hydropower construction is shut off by the shut-off assembly inside the valve body. The threaded column is driven to rotate by rotating the turntable. The threaded column rotates and rises and falls inside the support beam, so that the lower end of the threaded column drives the shut-off assembly to rise or fall, and controls the opening and closing of the shut-off device. The shut-off device has a simple structure, is easy to operate, and has strong stability.

With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: when the device is performing interception work, multiple groups of strip grooves are set up to reduce the impact of water flow on the device. However, during the interception process, the water flow often carries some garbage and stones with it. These garbage and stones are easily stuck in the strip grooves, and the garbage and stones stuck in the strip grooves need to be cleaned up. At the same time, garbage and stones may be brought down from upstream and clog the grid, which is inconvenient to clean.

It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

Example:

Please refer to Figures 1-3. A flow intercepting device for water conservancy construction in this embodiment includes a mounting frame 1. A motor 2 is installed on the top of the mounting frame 1. One end of the output shaft of the motor 2 is rotatably connected to a mounting seat. The bottom end of the mounting seat is fixedly connected to the top of the mounting frame 1 to ensure the normal operation of the motor 2. A pay-off wheel 3 is sleeved on the outer side of the output shaft of the motor 2. A pull rope 4 is connected to the surface of the pay-off wheel 3. A square groove for the pull rope 4 to pass through is opened on the top of the mounting frame 1 to ensure the normal operation of the pull rope 4. A sealing component is installed at the bottom end of the pull rope 4.

The blocking component is used to intercept the water flow. The blocking component includes a blocking plate 5 fixedly connected to the bottom end of the pull rope 4. The blocking plate 5 is slidably set on the inner wall of the mounting frame 1. Both sides of the inner wall of the mounting frame 1 are provided with lifting grooves for the blocking plate 5 to move, so as to ensure that the blocking plate 5 does not deviate during the movement. The four corners of the front side of the blocking plate 5 are fixedly connected with connecting rods 6, one end of the two upper connecting rods 6 is fixedly connected with toothed plates 7, and one end of the two lower connecting rods 6 is slidably connected with an L-shaped plate 8. The toothed plate 7 is slidably set in a sliding groove opened at the top of the L-shaped plate 8, one end of the toothed plate 7 is fixedly connected with a T-shaped connecting plate, and one side of the inner wall of the sliding groove is opened There is a T-shaped groove for the T-shaped connecting plate to slide, which prevents the tooth plate 7 from shifting during movement. The surface of the tooth plate 7 is meshed with the gear A9, and the surface of the gear A9 is meshed with the gear B10. A placement groove is provided on one side of the L-shaped plate 8, and the gear A9 and the gear B10 are both installed in the placement groove. The placement groove is connected to the bottom end of the sliding groove to ensure that the tooth plate 7 and the gear A9 can mesh normally. The outer side of the intermediate shaft of the gear B10 is sleeved with a bottom plate 11, and a grid plate 12 is fixedly connected between the two L-shaped plates 8. The surface of the grid plate 12 is provided with strip grooves at equal intervals to facilitate the diversion of the water flow. A cleaning component is installed between the grid plate 12 and the sealing plate 5.

The cleaning assembly includes two rotating rods 13, and two water wheels 15 are sleeved on the surface of the lower rotating rod 13. Both ends of the rotating rod 13 are installed with seat bearings, one end of the seat bearing is fixedly connected to the back of the grid plate 12, and the two rotating rods 13 are connected by a synchronous belt 14. Cleaning parts 16 are installed at equal intervals on the surface of the synchronous belt 14. The cleaning parts 16 include a long rod, one end of the long rod is fixedly connected to the surface of the synchronous belt 14, and cleaning rods compatible with the grid plate 12 are fixedly connected to the surface of the long rod at equal intervals, so as to facilitate the cleaning of the grid plate 12.

The implementation principle of a water conservancy construction interception device in the embodiment of the present application is: when the interception work is performed, the motor 2 is started, and the motor 2 drives the pay-off wheel 3 to rotate. Under the action of gravity and the pull rope 4, the blocking plate 5 gradually begins to descend. During the descent, the grid plate 12 first abuts against the bottom, and the grid plate 12 diverts the water flow, so that the impact force of the water flow becomes smaller, and the blocking plate 5 continues to descend until the blocking plate 5 abuts against the bottom, completing the interception of the water flow, reducing the impact force of the water flow on the blocking plate 5 during the interception work, and making the interception work more stable.

During the descent of the blocking plate 5, the toothed plate 7 drives the gear A9 to rotate, so that the gear A9 drives the gear B10 to rotate, so that the bottom plate 11 gradually tends to be horizontal. When the blocking plate 5 descends to the bottom, the bottom plate 11 just tends to be horizontal, so that during the interception work, impurities such as garbage and stones in the water flow fall onto the bottom plate 11. When the interception work is completed, under the action of the toothed plate 7, the gear A9 rotates, and under the action of the gear B10, one end of the bottom plate 11 tilts upward. During the rising process of the blocking plate 5, the bottom plate 11 will pick up impurities such as garbage, which is convenient for subsequent cleaning work and reduces the situation where the picked up garbage falls.

When the interception work is performed, the water flow continuously flushes the water wheel 15, so that the water wheel 15 drives the rotating rod 13 below to rotate. Under the action of the synchronous belt 14, the two rotating rods 13 rotate at the same time, so that the synchronous drive 14 drives the cleaning member 16 to continuously clean the strip grooves on the grid plate 12, preventing garbage from being blocked in the grid plate 12, thereby improving the garbage cleaning effect of the device.

The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
