Description

Technical Field

[0001] The utility model belongs to the technical field of flood control in water conservancy projects, and particularly relates to a combined flood control box for water conservancy projects. Background Technique

[0002] Water conservancy projects are divided into flood control projects, farmland water conservancy projects, hydropower projects, waterway and port projects, water supply and drainage projects, environmental water conservancy projects, coastal reclamation projects, etc. according to their service objects. A water conservancy project that can serve multiple objectives such as flood control, water supply, irrigation, and power generation at the same time is called a comprehensive utilization water conservancy project. Different types of hydraulic structures such as dams, levees, spillways, sluice gates, intakes, channels, aqueducts, raft channels, and fishways need to be built for water conservancy projects to achieve their objectives.

[0003] When the flood season comes, it is necessary to set up flood control walls to block the water flow and protect the villages. However, most of the current flood control walls are composed of sandbags, which require filling sand into gunny bags and carrying them to the flood control area for placement. This is very laborious and requires a large amount of manpower, which is rather troublesome. Content of the Utility Model

[0004] In order to solve the above problems, the purpose of the utility model is to provide a combined flood control box for water conservancy projects.

[0005] To achieve the above object, the utility model provides a combined flood control box for water conservancy projects, including a box body. Counterweight blocks are fixedly connected to both sides of the box body. Positioning nails are fixedly connected to the lower surfaces of the two counterweight blocks. Jacks are provided on the upper surfaces of the two counterweight blocks. The positions of the jacks correspond to the positioning nails, and the shapes of the jacks are the same as those of the positioning nails. A vertical pipe is fixedly connected to the upper surface of the box body, and the vertical pipe is communicated with the inside of the box body. A circular through groove is provided at the bottom of the box body. An installation groove is provided on the bottom surface inside the box body, and a cover plate is rotatably connected in the installation groove. The installation groove is communicated with the circular through groove, and a torsion spring is provided at the connection between the cover plate and the box body.

[0006] In one example, a circular groove is provided at the bottom of the box body. A rubber ring is fixedly connected to the upper surface of the box body. The centers of the rubber ring, the circular groove, the circular through groove, and the vertical pipe are on the same axis. The outer diameter of the vertical pipe is the same as the inner diameter of the rubber ring, and the outer diameter of the rubber ring is the same as the circular groove.

[0007] In one example, a slot is provided on one side of one of the counterweight blocks, and a plug rod is fixedly connected to one side of the other counterweight block. The positions of the slot and the plug rod correspond to each other, and the shapes of the slot and the plug rod are the same.

[0008] In one example, one side of the box is slidably connected to four sliding rods, and the four sliding rods all penetrate the box. One end of the four sliding rods is fixedly connected to a buffer plate, which is located outside the box. The other end of the four sliding rods is fixedly connected to a push plate, which is located inside the box.

[0009] In one example, springs are sleeved on the outer sides of the four sliding rods, one end of the four springs is fixedly connected to the inner wall of the box body, and the other end is fixedly connected to the push plate.

[0010] In one example, the buffer plate is in an arc shape, and the inner arc surface of the buffer plate is fixedly connected to a plurality of wave-breaking blocks, and all the wave-breaking blocks are arranged in an array.

[0011] The combined flood prevention box for water conservancy projects proposed by the utility model can bring the following beneficial effects:

[0012] First, by setting up vertical pipes and cover plates, the boxes are arranged to form a wall. When stacked, the vertical pipe on the lower box enters the circular groove at the bottom of the upper box, and the cover plate in the upper box is pushed open, so that the upper box is connected with the lower box. At this time, all the boxes are connected vertically, and river water is directly pumped out by a pump and injected into the top box. The river water gradually flows downward until all the boxes are filled. Under the gravity of the river water and the counterweight block, the positioning nails are inserted into the soil more firmly. When placing and transporting the box, the inside is hollow and the weight is not large, which is convenient for moving and placing. Using river water to increase the weight and using local materials is more convenient and labor-saving.

[0013] Secondly, by arranging a buffer plate, a wave-breaking block, a spring and a pushing plate, the water flow first impacts the wave-breaking block, which weakens the impact of the river water and reduces the impact of the river water on the box body, and then impacts the inner side of the buffer plate. The arc surface on the inner side of the buffer plate can provide a reverse guiding effect for the impacting river water to prevent the river water from crossing the box body. When the river water impacts the buffer plate, the spring is compressed when the sliding rod moves to buffer the impact, and the sliding rod pushes the pushing plate to move in the box body. Since the box body is full of river water, the pushing plate is blocked by the river water when it moves, and the force is unloaded. Through multiple unloading and buffering, the impact of the water flow on the box body is weakened. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] As Figures 1 to 4 shown, an embodiment of the present utility model provides a combined flood control box for water conservancy projects, including a box body 1. Counterweight blocks 2 are fixedly connected to both sides of the box body 1. Positioning nails 3 are fixedly connected to the lower surfaces of the two counterweight blocks 2. Jacks 4 are provided on the upper surfaces of the two counterweight blocks 2. The positions of the jacks 4 correspond to the positioning nails 3, and the shapes of the jacks 4 are the same as those of the positioning nails 3. A vertical pipe 5 is fixedly connected to the upper surface of the box body 1, and the vertical pipe 5 is communicated with the inside of the box body 1. A circular through groove is provided at the bottom of the box body 1. An installation groove is provided on the bottom surface inside the box body 1. A cover plate 6 is rotatably connected in the installation groove, and the installation groove is communicated with the circular through groove. A torsion spring is provided at the connection between the cover plate 6 and the box body 1. This flood control box is used for flood control of dikes. When in use, on the dike, a row of box bodies 1 are neatly placed on the dike. The positioning nails 3 on both sides of each box body 1 are inserted into the soil as the bottom layer of the base. Then, stacking is carried out on this box. When stacking, the positioning nails 3 on the upper box body 1 are inserted into the jacks 4 on the lower counterweight blocks 2. When inserting, the vertical pipe 5 on the lower box body 1 enters the circular through groove at the bottom of the upper box body 1, pushing open the cover plate 6 inside the upper box body 1, so that the upper box body 1 is communicated with the lower box body 1. When a certain height is placed, all the box bodies 1 in the vertical direction are communicated at this time. The river water is directly pumped by a water pump and injected into the uppermost box body 1. The river water gradually flows downward until all the box bodies 1 are filled. Under the gravity of the river water and the counterweight blocks 2, the positioning nails 3 are inserted into the soil more firmly. Thus, continue to place until a wall composed of box bodies 1 is placed to resist impact and make the box bodies 1 more stable. When placing and transporting the box bodies 1, they are hollow inside and not heavy, which is convenient for moving and placing. After placing, river water is injected into the box bodies 1 for weight gain, making use of local materials, which is more convenient and labor-saving.

[0027] Specifically, a circular groove is provided at the bottom of the box body 1. A rubber ring 7 is fixedly connected to the upper surface of the box body 1. The centers of the rubber ring 7, the circular groove, the circular through groove, and the vertical pipe 5 are on the same axis. The outer diameter of the vertical pipe 5 is the same as the inner diameter of the rubber ring 7, and the outer diameter of the rubber ring 7 is the same as the circular groove. When the box bodies 1 are stacked vertically, at this time, the lower vertical pipe 5 is inserted into the upper box body 1. After insertion, at this time, the rubber ring 7 enters the circular groove. The thickness of the rubber ring 7 is the same as the depth of the circular groove. The rubber ring 7 blocks the gap between the vertical pipe 5 and the circular through groove, preventing water from flowing out through the gap and causing the box body 1 to be unstable.

[0028] Specifically, a slot 8 is provided on one side of one of the counterweight blocks 2, and a plug rod 9 is fixedly connected to one side of the other counterweight block 2. The positions of the slot 8 and the plug rod 9 correspond to each other, and the shapes of the slot 8 and the plug rod 9 are the same. Adjacent box bodies 1 can be plugged through the slot 8 and the plug rod 9, making the box bodies 1 connected more tightly in the horizontal direction, preventing the box bodies 1 in different columns from tilting and large gaps from appearing between adjacent box bodies 1.

[0029] Specifically, four sliding rods 10 are slidably connected to one side of the box body 1. The four sliding rods 10 all penetrate the box body 1. One end of the four sliding rods 10 is fixedly connected to a buffer plate 11. The buffer plate 11 is located outside the box body 1. The other end of the four sliding rods 10 is fixedly connected to a push plate 12. The push plate 12 is located inside the box body 1. When the river water impacts on the buffer plate 11, the buffer plate 11 pushes the push plate 12 to move inside the box body 1 through the sliding rods 10. Since the box body 1 is filled with river water, the push plate 12 is blocked by the river water when moving, forming a certain force-relieving effect.

[0030] Specifically, springs 13 are sleeved on the outer sides of the four sliding rods 10. One end of the four springs 13 is fixedly connected to the inner wall of the box body 1, and the other end is fixedly connected to the push plate 12. When the river water impacts the buffer plate 11 and the sliding rods 10 move, the springs 13 are compressed to buffer the impact, preventing the impact from directly acting on the box body 1 and causing the box body 1 to tilt.

[0031] Specifically, the shape of the buffer plate 11 is arc-shaped. A plurality of wave-dissipating blocks 14 are fixedly connected to the inner arc surface of the buffer plate 11. All the wave-dissipating blocks 14 are arranged in an array. The water flow first impacts on the inner side of the buffer plate 11. The inner arc surface of the buffer plate 11 can provide a reverse guiding effect on the incoming river water, preventing the river water from flowing over the box body 1. When the river water first impacts on the wave-dissipating blocks 14, the wave-dissipating blocks 14 weaken the impact of the river water and reduce the impact of the river water on the box body 1.

[0032] Working principle: On the dam, a row of boxes 1 are neatly placed on the dam. The positioning pins 3 on both sides of each box 1 are inserted into the soil. Adjacent two boxes 1 are plugged together through the slot 8 and the insertion rod 9. Then, the boxes 1 are placed in the upper layer, so that the positioning pins 3 on the upper box 1 are inserted into the jacks 4 on the lower counterweight 2. When inserting, the vertical pipe 5 on the lower box 1 enters the circular through groove at the bottom of the upper box 1, pushing open the cover plate 6 in the upper box 1, making the upper box 1 communicate with the lower box 1. When a certain height is placed, at this time, all the boxes 1 in the vertical direction are communicated. The river water is directly pumped by a water pump and injected into the uppermost box 1. The river water gradually flows downward until all the boxes 1 are filled. When the water flow impacts, it first impacts on the wave dissipating block 14, and the wave dissipating block 14 weakens the impact of the river water. Then it impacts on the inner side of the buffer plate 11. The arc surface on the inner side of the buffer plate 11 can provide a reverse guiding effect on the impacting river water. When the river water impacts the buffer plate 11 and the sliding rod 10 moves, the spring 13 is compressed to buffer the impact. The sliding rod 10 pushes the push plate 12 to move in the box 1. Since the box 1 is filled with river water, when the push plate 12 moves, it is blocked by the river water to unload the force.
