Description

Flood prevention device

Technical Field

The invention relates to the technical field of flood prevention and water blocking, in particular to a flood prevention device.

Background

As the water level is constantly changed due to the tidal change of rivers or seawater in nature, particularly the flood caused by heavy rain and the change of the height of a riverbed, once a heavy tide or a flood peak occurs, the water level exceeds the dam built on the river bank, and great damage is caused to the life of people. Especially, when the water flow of the flood peak reaches the dam for the first time, the impact force of the water flow to the dam is the largest, once the dam has water with a certain depth, the force borne by the dam mainly comes from the pressure of the water flow, the impact force of the water flow borne by the dam is weakened, and if the dam can resist the impact of the flood peak every time, the probability of dam break is greatly reduced. The traditional flood prevention facilities are sand bags, and the sand piles with certain height and length are stacked to play a role in flood prevention, so that the sand bags can play a role in buffering and energy absorption to a certain extent, and the impact force of water flow is reduced; however, the sand pile is formed by overlapping a plurality of sand bags, the impact resistance of the contact part of the adjacent sand bags is poor, the part is easily broken by water flow, and the sand pile is heavy and is difficult to carry; in recent years, various new flood prevention facilities appear, for example, a plurality of spliced steel plates are used for blocking water flow or heightening a dam to achieve the flood prevention purpose, but the steel plates lack an effective buffer structure, have poor water flow impact resistance, are easy to bend or are easy to crack at the joint of the adjacent steel plates when the water flow directly impacts the steel plates, and are easy to cause dam break.

Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.

The flood prevention device shown in the figures 1-5 is formed by splicing and combining a plurality of independent flood prevention units, adjacent flood prevention units are connected through connecting pieces in a threaded mode, the connecting pieces can be metal blocks or sealing metal strips, and only the steel plates 3 of the two flood prevention units need to be connected into a whole, and the connecting pieces can be in the prior art. The flood prevention device formed by connecting and assembling the plurality of flood prevention units is shown in fig. 5.

As shown in fig. 1, the flood prevention unit comprises a bottom plate 1, a support frame 2, a steel plate 3, an energy absorption sponge 4, a buffer baffle 5 and a buffer stop strip 6;

the bottom plate 1 is horizontally arranged, and the steel plate 3 is obliquely arranged above the bottom plate 1 and is connected with the bottom plate through a plurality of support frames 2; an energy-absorbing sponge 4 with the thickness more than 1cm is paved on the inclined plane of the steel plate 3 back to the bottom plate 1; the lower end face of the bottom plate 1 can be provided with an anti-skid groove, the edge of the bottom plate 1 can be provided with a through hole for inserting a bolt, and the bolt is inserted into the ground so as to firmly fix the bottom plate 1 on the ground.

The steel plate 3 comprises at least two inclined sections and horizontal sections which are integrally formed, the horizontal sections are positioned among the plurality of inclined sections, the number of the inclined sections is two in the embodiment, the specific height of each inclined section can be set to be different according to different types of flood prevention devices, for example, the height of each inclined section can be 1m or 0.5 m; the distance between the inclined planes of the inclined sections back to the bottom plate 1 is provided with a buffer baffle 5; a plurality of buffer stop bars 6 are arranged on the horizontal plane of the horizontal section back to the bottom plate 1; the buffer stop strips 6 are arranged in a staggered way. The heights of the plurality of buffer bars 6 are gradually increased in a direction in which the steel plate 3 is inclined upward. Buffering blend stop 6 not only can play the effect of slowing down rivers impact force, because its setting is at the horizontal segment of steel sheet 3, the buffering blend stop 6 after absorbing moisture has effectively increased the perpendicular decurrent pressure that steel sheet 3 received moreover, makes the difficult emergence displacement of flood prevention unit, is applicable to the earth ground that is not convenient for insert the bolt.

The buffer baffle 5 is connected with the steel plate 3 through connecting rods 7 arranged on two opposite sides of the buffer baffle 5, the buffer baffle 5 comprises two half plates 8, the adjacent sides of the half plates 8 are abutted, the opposite sides are hinged with the connecting rods 7, and buffer springs 10 are connected between the half plates 8 and the steel plate 3; the two half plates 8 are connected with a net bag 9, and two ends of the net bag 9 are respectively connected with the two half plates 8. When the buffer baffle 5 is impacted by water flow, the abutting part of the half plate 8 is pushed open, the buffer spring 10 is compressed, the water flow passes through the net bag 9 and then impacts the energy-absorbing sponge 4 at the position corresponding to the buffer baffle 5, and finally impacts the steel plate 3 at the corresponding position; when the impact force of the water flow is reduced, the buffer spring 10 returns to push the half plate 8 back, and the water flow impacting the steel plate 3 at the corresponding position is reduced. Buffer baffle 5 and the 3 slope sections of steel sheet that correspond form a buffer area, and rivers strike steel sheet 3 after the buffer area earlier, effectively reduce the impact force, and the rivers striking steel sheet 3 of buffer area turn to the in-process after meet energy-absorbing sponge 4, buffer baffle 5, buffering blend stop 6, its power attenuates gradually, and the impact force reduces gradually.

The buffer barrier strip 6 is flexible and comprises two carbon fiber nets 11, two sponge strips 12 and a plurality of sponge particles 13; two carbon fiber nets 11 and two sponge strips 12 are alternately connected to form a hollow pipe body; a plurality of sponge particles 13 are arranged in the tube body at intervals longitudinally. When rivers strike buffering blend stop 6, as shown in fig. 2, buffering blend stop 6 is crooked along the rivers direction, and because two offsides of body are carbon fiber net 11, water can be smoothly through in the carbon fiber net 11 admission pipe of one side, nevertheless because the internal interval of body is equipped with polylith sponge grain 13, the rivers that get into in the pipe need pierce through behind the polylith sponge grain 13 just can follow the carbon fiber net 11 outflow of opposite side, and velocity of water and impact force are all reduced. The sponge particles 13 after water absorption increase the weight of the buffer stop bars 6, so that the vertical pressure of the horizontal section is further increased, the pressure of the whole flood prevention unit on the ground is higher, and the flood prevention unit is not easy to be broken down.
