Description

Technical Field

[0001] The present invention relates to the technical field of interception devices, and more specifically, to an interception device and an interception method for water conservancy construction. Background Art

[0002] Interception is a key project in the construction of water conservancy projects. During the construction of water conservancy projects, it is often necessary to cut off the water flow in the ditch and divert the water to the discharge structure so that construction can be carried out in the ditch. This is called interception. Most of the existing interception technologies use large stones or concrete and other materials to build dams by bulldozers to intercept the ditch. However, building dams for interception is not stable enough and may leak, resulting in insufficient interception. Therefore, an interception device is needed to perform a more stable interception operation.

[0003] However, there are various types of interception devices in the prior art. For example, invention patent CN112942261A involves an interception method and device for water conservancy construction. The interception device for water conservancy construction described in the invention includes a gate pier mechanism and a gate frame. The interception method includes the following steps: placing the gate frame horizontally above the river, hoisting the gate pier mechanism from the gate frame into the river to be intercepted; squeezing the side of the gate pier mechanism into the side wall of the river. The present invention realizes the preset gate pier mechanism and installs it on the river, and then assembles the gate assembly on the gate pier mechanism to finally intercept the river. The interception device can be directly assembled and used on the river, without the need for gate pier construction on both sides of the river, so as to quickly intercept the river, with high construction speed and low cost, and easy disassembly for reuse.

[0004] Although the intercepting device can quickly intercept the river channel, has a fast construction speed and is easy to reuse, during use, due to the excessive weight of the gate, the traction rope will exert all the pressure on the traction rope during the long period of lifting the gate, which can easily cause the traction rope to break, thereby damaging the intercepting device, affecting the normal operation of the device, and reducing the service life of the device. In order to avoid this phenomenon, it is very necessary to design a water conservancy construction intercepting device and intercepting method. Summary of the invention

The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0022] Embodiment 1: Figure 1 as well as Figure 3 As shown, it is a structural schematic diagram of the water conservancy construction intercepting device in this embodiment. In this embodiment, the intercepting device includes a gate seat 1, and the number of gate seats 1 installed is two. A support frame 3 is arranged on the top of the gate seat 1. Two symmetrically arranged mounting seats 4 are fixedly connected to the top of the support frame 3. A transmission shaft 5 is rotatably connected between the two mounting seats 4 through a bearing. Two symmetrical positioning coils 6 are coaxially arranged on the surface of the transmission shaft 5. A pulling rope 7 is wound on the surface of the positioning coil 6. A intercepting gate 2 is embedded in front of the two gate seats 1. One end of the pulling rope 7 is fixedly connected to the intercepting gate 2. When intercepting the river channel, the rotating transmission shaft 5 drives the two positioning coils 6 to rotate, so that the positioning coil 6 unwinds the wound pulling rope 7, and under the guidance of the slot 35 and the positioning convex strip 36, the pulling rope 7 drives the intercepting gate 2 to steadily descend, and the bottom of the intercepting gate 2 is embedded in the sealing seat 33. The blocked intercepting gate 2 can be used to intercept the river channel and cut off the water flow in the river channel; like Figure 4 as well as Figure 5As shown, in this embodiment, multiple groups of limit grooves 8 are provided on the surfaces of the two gate seats 1 close to each other, and two symmetrical guide slide grooves 9 are provided in the cut-off gate 2.

A rotating shaft 13 is rotatably connected to the inside of the mounting groove 12 through a bearing, and a driving bevel gear 14 is coaxially arranged on the surface of the rotating shaft 13. Two symmetrical threaded sleeves 15 are rotatably connected to the mounting groove 12 through a bearing, and the inner surfaces of the two threaded sleeves 15 are both threadedly connected with screws 17, and one end of the two screws 17 is fixedly connected to the movable block 10, and the outer surfaces of the two threaded sleeves 15 are coaxially arranged with driven bevel gears 16, and the two driven bevel gears 16 are located in the mounting groove 12 and are symmetrically distributed. The gears 16 are meshed and connected with the active bevel gear 14; when the intercepting gate 2 is lifted by the pulling rope 7, the gap in the river channel is released, and the intercepted river channel is released. After the two supporting blocks 11 are connected to any group of limiting grooves 8 at the same height, the active bevel gear 14 is driven to rotate by the rotating rotating shaft 13, and the two driven bevel gears 16 are driven to rotate by the transmission effect between the active bevel gear 14 and the two driven bevel gears 16. Since the rotation directions of the two driven bevel gears 16 are opposite, the threaded sleeve 15 and the threaded cooperation of the screw 17 are utilized to extend the two screws 17 in two opposite directions, and at the same time, the two movable blocks 10 are pushed to press the two supporting blocks 11 into the corresponding group of limiting grooves 8, thereby supporting and fixing the suspended intercepting gate 2, reducing the pressure on the pulling rope 7, and preventing the pulling rope 7 from breaking and damaging the device, so as to ensure the normal operation of the intercepting device and improve the service life of the device.

After the collection box 26 has been stationary for a long time, since the direction of the river channel water flow is from the wider opening of the gate seat 1 to the narrower opening, the garbage floating on the water surface will float from the opening of the gate seat 1 to the collection port 29 and enter the collection box 26. After a certain amount of garbage is collected in the box, the collection box 26 is lifted again by the movable seat 23, and the filter screen 28 is set to filter out the river water.
