Under the condition that water collection tank 21 is full of river water, the gravity of water collection tank 21 is greater than the gravity of baffle 13, and after water collection tank 21 is full of river water, river water continuously flows to the side of separation plate 22 away from water inlet 121, so that the gravity of water collection tank 21 is continuously increased, and the gravity of water collection tank 21 is far greater than the gravity of baffle 13. Along with that, the water collecting tank 21 pulls the pull rope 25 under the action of gravity, and the pull rope 25 pulls the baffle 13 to rise quickly, so that the effect of automatically lifting the baffle 13 is achieved, the rising speed of the baffle 13 is increased, and the baffle 13 can rapidly cut off river water conveniently.

In addition, the river water in the water storage tank 12 can generate buoyancy on the baffle 13, so that the baffle 13 can be conveniently and quickly lifted by the pull rope 25.

Meanwhile, two pairs of guide wheels 26 are arranged on the base plate 11 and the support beam 24, and the two pairs of guide wheels 26 are symmetrically arranged along the central line of the vertical direction of the bracket. One of the guide wheels 26 of the same pair is rotatably connected to the base plate 11 and the other is rotatably connected to the support beam 24. And a pair of guide wheels 26 correspond to one pull rope 25, the guide wheels 26 are I-shaped wheels, and the pull rope 25 is wound around the same pair of guide wheels 26 and is embedded in a groove of the guide wheels 26. The guide wheel 26 can limit the moving direction of the pull rope 25, so that the possibility of deviation of the pull rope 25 is reduced, and the stability of the pull rope 25 in the process of lifting the baffle 13 is improved.

And stay cord 25 is at the in-process that removes, and stay cord 25 and leading wheel 26 produce the friction, drive leading wheel 26 and produce the rotation, and leading wheel 26 can be with the friction conversion between stay cord 25 and a supporting beam 24 and the base plate 11 rolling friction this moment to leading wheel 26 has reduced the frictional force between stay cord 25 and a supporting beam 24 and the base plate 11, and then the quick subsidence of water catch bowl 21 of being convenient for, so that baffle 13 is quick risees.

One side, opposite to the two support columns 101, of each support column is provided with a sliding groove 231 in the vertical direction, the baffle 13 is arranged in the two sliding grooves 231 in a sliding mode, and the sliding grooves 231 can limit the moving direction of the baffle 13, so that the baffle 13 is guided, and the stability of the baffle 13 in moving is improved; meanwhile, the sliding groove 231 has a limiting effect on the baffle 13, and the matching stability between the baffle 13 and the support is improved, so that the situation that the baffle 13 is separated from the support frame 1 is reduced.

Referring to fig. 3 and 5, sealing member 4 includes sealing plate 41 for sealing water-permeable hole 221, two guide grooves 42 are fixedly connected to one side of partition plate 22 away from water collecting tank 21 along the vertical direction, water-permeable hole 221 is located between two guide grooves 42, and sealing plate 41 is slidably disposed in two guide grooves 42. A pulling rope 43 for connecting the water collecting tank 21 and the sealing plate 41 is arranged on the base plate 11 in a penetrating manner, one end of the pulling rope 43 penetrates through the base plate 11 to be fixed on the side wall of the water collecting tank 21 close to the partition plate 22, and the other end penetrates through the base plate 11 to be fixed on the top of the sealing plate 41. The side of the base plate 11, which faces away from the partition plate 22, is rotatably connected with a pulley 44, the traction rope 43 is wound around the pulley 44, and the vertical part of the traction rope 43 is tangent to the outer edge of the pulley 44.

In a normal state, the bottom wall of the sealing plate 41 abuts against the bottom wall of the reservoir 12. When the water collection tank 21 begins to sink, the water collection tank 21 pulls the pulling rope 43, so that the pulling rope 43 drives the sealing plate 41 to rise. When the roof that up to sealing plate 41 contradicts on base plate 11, sealing plate 41 and the coincidence of the hole 221 of permeating water to carry out the shutoff to the hole 221 of permeating water, in order to reach the effect of sealed hole 221 of permeating water, avoided the river to continue to get into the cavity that division board 22 deviates from water inlet 121 one side through the hole 221 of permeating water, lead to the river to take place from the condition that traction hole 112 gushed. Meanwhile, the traction rope 43 drives the pulley 44 to roll, so that the friction force between the pull rope 25 and the base plate 11 is reduced, and the smoothness of the sealing plate 41 during lifting is improved.

In addition, a magnet block 45 is fixedly connected to both one side of the water collecting tank 21 facing the bottom wall of the water storage tank 12 and the bottom wall of the water storage tank 12. When the water collecting groove 21 sinks, the two magnet blocks 45 approach each other until the sealing plate 41 seals the water permeable hole 221, the attraction force between the two magnet blocks 45 continues to increase, and at this time, a small gap exists between the two magnet blocks 45, so that the water collecting groove 21 can keep a downward pulling force, and the tightness between the sealing plate 41 and the partition plate 22 is improved. Meanwhile, the tensile force of the water collecting groove 21 on the baffle 13 is increased, and the matching firmness between the baffle 13 and the bracket is further increased.

Referring to fig. 6 and 7, the baffle 13 is provided with the anti-disengaging part 3, the anti-disengaging part 3 comprises a limiting rod 31, a roller 32 and a spring 33, a hinge groove 131 used for accommodating the limiting rod 31 is formed in the side wall of the baffle 13 along the vertical direction, one end of the limiting rod 31 is hinged to the upper portion of the hinge groove 131 and is close to the upper end face, and the roller 32 is rotatably connected to the other end of the limiting rod 31. The spring 33 is fixedly connected to the wall surface of the limiting rod 31 facing the bottom wall of the hinge groove 131, and the other end of the spring 33 abuts against the bottom wall of the hinge groove 131. Meanwhile, the support rod 23 is provided with a limit groove 232 for the limit rod 31 to extend into on one side of the guide groove 42 facing the baffle 13. When the flap 13 abuts against the support beam 24, the stopper groove 232 is aligned with the opening of the hinge groove 131.

In a normal state, the baffle 13 is positioned in the water storage tank 12, the limiting rod 31 is positioned in the hinge groove 131, the limiting rod 31 extrudes the spring 33 at the moment, the spring 33 is compressed to have elastic restoring force, and the spring 33 pushes the limiting rod 31 to approach the side wall of the water storage tank under the action of the elastic restoring force, so that the roller 32 is abutted against the side wall of the water storage tank 12.

When the baffle 13 rises, the roller 32 rubs against the side wall of the water storage tank 12 or the support rod 23, so that the roller 32 rolls, the friction force between the baffle 13 and the side wall of the water storage tank 12 or the support rod 23 is reduced, and the fluency of the baffle 13 when rising is further improved. When the stop rod 31 is aligned with the stop groove 232, the spring 33 pushes the stop rod 31 and the roller 32 to extend into the stop groove 232 under the action of the elastic restoring force.

When the connection between the pulling rope 25 and the baffle 13 is separated or the pulling rope 25 is broken, the baffle 13 loses the tension of the water collecting groove 21 and slides down under the gravity of the baffle 13. At this moment, the limiting groove 232 can limit the baffle 13 through the limiting rod 31, so that the anti-slip piece 3 can limit the baffle 13, the baffle 13 is prevented from sliding downwards in the flood prevention process, and the flood prevention failure of the flood prevention device is avoided.

In addition, a waist-shaped hole 233 communicated with the limiting groove 232 is formed in one side, away from the baffle 13, of the support rod 23, and an operator can push the limiting rod 31 into the hinge groove 131 through the waist-shaped hole 233, so that the limiting rod 31 is separated from the limiting groove 232, and the operator can conveniently recover the baffle 13 into the water storage tank 12.

The implementation principle of the river flood prevention device in the embodiment of the application is as follows: in the process of flood prevention of the river channel, an operator firstly places the support frame 1 at a proper position of the river channel, and the water inlet 121 faces one side of the river channel water expansion. And simultaneously, a pit needs to be dug at the bottom of the riverbed, so that the bottom of the water storage tank 12 is buried in the pit, and the firmness between the water storage tank 12 and the riverway is improved. Then, the operator rotates the threaded rod 64, so that the threaded rod 64 pushes the positioning plate 62 to be inserted into soil on the edge of the river channel, and the aim of fixing the support frame 1 is fulfilled. And then burying the periphery of the flood prevention device to increase the sealing property between the flood prevention device and the river channel.

When the liquid level of the river in the river channel exceeds the height of the floating ball 57, the river generates buoyancy on the floating ball 57, so that the floating ball 57 drives the shifting plate 56, the shifting plate 56 drives the positioning shaft 54 to rotate, and the positioning shaft 54 drives the water baffle 55 to separate from the water inlet 121. Meanwhile, the positioning shaft 54 winds the connecting rope 58 and drives the swing rod 51 to swing, so that the pressing plate 52 is separated from the positioning rod 53, and the clamping piece 5 releases the fixing of the cover plate 14. At this time, the water in the river channel enters the water storage tank 12 through the water inlet 121, so that the liquid level in the water storage tank 12 continuously rises, and as the river water in the water storage tank 12 continuously increases, the river water generates certain buoyancy to the baffle 13, so that part of the baffle 13 extends out of the through holes 111.

Until the liquid level in the cavity of the partition plate 22 facing the water inlet 121 side is higher than the bottom wall of the water permeable hole 221, the river water enters the side of the partition plate 22 departing from the water inlet 121 through the water permeable hole 221 and enters the water collecting tank 21, thereby increasing the gravity of the water collecting tank 21 itself. When the gravity of the water collecting tank 21 is larger than that of the baffle 13, the water collecting tank 21 drives the baffle 13 to ascend. Meanwhile, under the action of buoyancy, river water in the water storage tank 12 has a certain boosting effect on the baffle 13, so that the baffle 13 can rise quickly. The limiting rod 31 extends into the limiting groove 232 until the bottom wall of the baffle 13 abuts against the supporting beam 24, so as to prevent the baffle 13 from sliding down when the baffle 13 loses the pulling force of the water collecting groove 21.

At this time, water collection tub 21 pulls sealing plate 41 upward until sealing plate 41 seals water permeable hole 221, and the river stops flowing to the side of partition plate 22 away from water inlet 121.

The embodiment of the application also discloses a construction method of the river flood prevention device.
