Description

Technical Field

[0001] The invention belongs to the technical field of flood control buildings, and in particular is an outer wall of a flood control building used in a polder area. Background Art

[0002] Flood control areas are areas where dikes are built to protect against flooding and where agricultural production is practiced. Traditional riverside architecture in flood control areas, with houses situated along the riverbanks or even directly adjacent to it, often remains below the waterline for extended periods during flood season, with exterior walls subject to floodwater impact and submersion.

[0003] In the existing technology, the outer walls of flood-control buildings in the embankment area are mostly designed with the impact resistance and waterproofing capabilities of the walls in mind. However, in some building areas connected to the river, when the flood season comes, not only will the flood impact the outer walls, but the silt brought by the flood will also impact the walls. More often, the silt is deposited in the river under the influence of the water flow, especially in some curved river bends, where a large amount of silt is deposited, causing the riverbed to rise and the water level to further increase. Therefore, improvements are made to the outer walls of flood-control buildings to address the above problems. Summary of the Invention

[0005] In order to solve the problems raised in the above-mentioned background technology, the present invention provides an outer wall of a flood-control building applied to a polder area, which pushes the sediment through the impact force of the water above. The sediment cleaning component rotates clockwise, and after pushing the sediment, the second movable component contacts the telescopic sleeve and under the action of pressure, the second sediment baffle and the end not connected to the first sediment baffle approach each other, and then squeeze the cleaning baffle, so that the cleaning baffle moves outward along the angle formed by the first sediment baffle and the second sediment baffle, further pushing the sediment, so that the sediment separates from the inner side of the first sediment baffle and the second sediment baffle, and will not enter the placement trough with the rotation, and is discharged to the downstream of the river channel during the water flow movement inside the drainage trough to prevent deposition, which has the advantage of good sediment treatment effect.

[0017] (3) Beneficial effects

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 2. The present invention cooperates with the water-blocking assembly, the first telescopic assembly, and the first movable assembly. When water flows from upstream downward along the river channel and impacts the bottom retaining wall, the design of the water-blocking assembly and the sediment-clearing assembly can hinder the water flow to a certain extent, thereby driving the first connecting assembly and the second connecting column to rotate clockwise through the impact force of the water flow.

[0021] 3. The present invention cooperates with the telescopic sleeve, adjustment component, first connecting component and other structures. Through the telescopic sleeve, when the drive motor is started, the retractable telescopic sleeve can rotate the reel to reel in the connecting rope, thereby driving the first connecting component, water-blocking component, first telescopic component and other structures to move upward, adapting to the water level in different periods. In the non-flood season when the amount of sediment is small and the water flow is slow, the sediment clearing component will not be pushed by the water flow, reducing wear.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] like Figures 1 to 8As shown, the present invention provides an external wall of a flood control building used in a polder area, comprising a top retaining wall 1, a bottom retaining wall 2 fixedly installed at the bottom of the top retaining wall 1, a movable column 3 movably sleeved in the inner cavity of the bottom retaining wall 2, a first connecting component 4 and a second connecting column 5 sequentially arranged on the surface of the movable column 3 from top to bottom, a first connecting component 6 movably sleeved in an annular manner at equal angles on the outer surface of the first connecting component 4, a water-blocking component 7 movably sleeved at both ends of the middle portion of the first connecting block 6, a first telescopic component 8 fixedly installed at both ends of the outer surface of the first connecting block 6, and a first movable component fixedly connected to the end of the first telescopic component 8 away from the first connecting block 6 9. The outer surface of the second connecting column 5 is movably sleeved with a second connecting block 10 at an equal angle in an annular manner. The two ends of the middle part of the second connecting block 10 are movably sleeved with a sediment removal component 11. The two ends of the outer surface of the second connecting block 10 are fixedly mounted with a second telescopic component 12. The end of the second telescopic component 12 away from the second connecting block 10 is fixedly connected to a second movable component 13. The middle part of the sediment removal component 11 is movably sleeved with a cleaning baffle 14. A sliding track 15 is fixedly mounted on one side of the bottom of the bottom retaining wall 2. A telescopic sleeve 16 is symmetrically mounted on the top of the inner cavity of the bottom retaining wall 2. An adjustment component 17 is fixedly mounted on one end of the top of the bottom retaining wall 2.

[0033] The above scheme is adopted: the movable column 3 is limited by the bottom retaining wall 2 facing the river channel, and the movable column 3 limits the first connecting component 4 and the second connecting column 5. The first connecting component 4 and the second connecting column 5 rotate synchronously in the same direction with the movable column 3 as the center. When the water flows from the upstream downward along the river channel to impact the bottom retaining wall 2, the water flow can be hindered to a certain extent by the design of the water blocking component 7 and the sediment clearing component 11, so that the impact force of the water flow drives the first connecting component 4 and the second connecting column 5 to rotate clockwise. The rotation of the first connecting component 4 and the second connecting column 5 can convert the impact force generated by the water flow into a force that drives the first connecting component 4 and the second connecting column 5 to rotate. Since the expansion area of the water blocking component 7 is larger than the expansion area of the sediment clearing component 11, and the water blocking component 7 is located above the sediment clearing component 11, there is water above and sediment at the bottom in the flood. In this way, the bottom sediment clearing component 11 is driven to push the sediment by the impact force of the water above, and the arc direction of the sediment clearing component 11 is consistent with the water blocking component The arc direction of 7 is opposite, the water blocking component 7 can better withstand the impact of water, and the mud and sand cleaning component 11 can better push the mud and sand when it rotates clockwise, and through the design of the cleaning baffle 14 and the telescopic sleeve 16, the mud and sand cleaning component 11 is in clockwise rotation. After pushing the mud and sand, the second movable component 13 contacts the telescopic sleeve 16 and under the action of pressure, the second mud and sand baffle 112 and the end not connected to the first mud and sand baffle 111 are close to each other, thereby squeezing the cleaning baffle 14, so that the cleaning baffle 14 moves outward along the angle formed by the first silt baffle 111 and the second silt baffle 112, further pushing the silt to separate from the inner sides of the first silt baffle 111 and the second silt baffle 112, and to be discharged to the downstream of the river channel during the water flow movement inside the drainage trough 22 to prevent sedimentation. At the same time, the cooperation of the water blocking component 7 and the first telescopic component 8, the silt clearing component 11 and the second telescopic component 12 can reduce the overall length, and thus can move inside the placement trough 23 in a compressed state, such as Figure 5 and Figure 6 As shown in the right part, the overall thickness of the bottom retaining wall 2 is reduced.

[0034] like Figure 1 、 Figure 7 As shown, the bottom retaining wall 2 includes a bottom wall body 21 fixedly connected to the top retaining wall 1, a placement groove 23 is opened on the side of the bottom wall body 21 close to the river channel, and drainage grooves 22 are evenly distributed at the bottom of the bottom wall body 21. The drainage grooves 22 are located outside the bottom of the placement grooves 23. The second connecting column 5 is fixedly connected to the movable column 3, and the top and bottom of the movable column 3 are connected to the bottom retaining wall 2 through a second sealed bearing. The second sealed bearing is buried inside the bottom retaining wall 2;

[0035] The above-mentioned scheme is adopted: the bottom wall body 21 is used to limit the movable column 3, and the second sealed bearing provided therein can facilitate the rotation of the movable column 3. The drainage groove 22 can facilitate the entry of water, but cannot pass through mud and sand. Specifically, a filter structure can be set at the water inlet for filtering. At the same time, the drainage groove 22 is arc-shaped, which can reduce the impact force on the bottom wall body 21 by changing the direction of the water flow force when the water flows in, and when the water flows out through the drainage groove 22, it can impact the mud and sand pushed by the cleaning baffle 14 to prevent the mud and sand from being brought into the placement groove 23.

[0036] like Figure 1 、 Figure 8 As shown, the first connecting component 4 includes a first connecting column 41 movably sleeved with the movable column 3, the outer side of the top of the first connecting column 41 is fixedly installed with a first sealed bearing 42, the inner wheel of the first sealed bearing 42 is fixedly connected to the first connecting column 41, and the outer wheel of the first sealed bearing 42 is fixedly connected to the telescopic sleeve 16. The adjusting component 17 includes a connecting rope 171, one end of the connecting rope 171 passes through the telescopic sleeve 16 and is fixedly connected to the outer wheel of the first sealed bearing 42, and the other end of the connecting rope 171 is wrapped around the surface of the winding wheel 172, and the middle part of the winding wheel 172 is fixedly connected to the driving motor 173. The connecting rope 171 is located in the inner wall of the bottom retaining wall 2 and a fixed pulley is provided at its corner. The driving motor 173 is fixedly installed on the top of the bottom retaining wall 2. The shape of the telescopic sleeve 16 is "L"-shaped and the telescopic sleeve 16 is formed by movably sleeved round tubes whose diameters increase from bottom to top. When the connecting rope 171 is wound around the winding wheel 172, the telescopic sleeve 16 gradually shortens.

[0037] The above solution is adopted: the first sealed bearing 42 is set to ensure that the telescopic sleeve 16 remains stationary when the first connecting column 41 rotates, thereby ensuring that the connecting rope 171 will not be entangled. The telescopic sleeve 16 is retractable. When the drive motor 173 is started, the winding wheel 172 can be rotated to reel in the connecting rope 171, thereby driving the first connecting component 4, the water-blocking component 7, the first telescopic component 8 and other structures to move upward to adapt to the water level in different periods. The fixed pulley can reduce the friction of the connecting rope 171 when it is wound, thereby ensuring its service life and use effect.

[0038] like Figure 5 As shown, the water-blocking assembly 7 includes a first water-blocking baffle 71 movably connected to the first connecting block 6, and a second water-blocking baffle 72 movably connected to the end of the first water-blocking baffle 71 away from the first connecting block 6. The first water-blocking baffle 71 and the second water-blocking baffle 72 are both arc-shaped, and the drive motor 173 is provided with a stop structure. This is prior art and will not be described in detail.

[0039] With the above solution, the first water-blocking baffle 71 and the second water-blocking baffle 72 are movably sleeved together and can rotate clockwise under the impact of the water flow. Moreover, since the first water-blocking baffle 71 and the second water-blocking baffle 72 are formed as a whole and bulge outward in the direction of the water flow, the impact force of the water flow can be better absorbed, and the impact force of the water flow is effectively converted.

[0040] like Figure 5 As shown, the first telescopic assembly 8 includes a first movable sleeve 81 fixedly connected to the first connecting block 6, an end of the first movable sleeve 81 away from the first connecting block 6 is movably sleeved with a second movable sleeve 82, an end of the second movable sleeve 82 located inside the first movable sleeve 81 is fixedly connected to a first spring 83, an end of the second movable sleeve 82 away from the first movable sleeve 81 is fixedly connected to the first movable assembly 9, the first movable assembly 9 includes a first positioning block 91, a first roller 92 is connected to the lower end bearing of the outer surface of the first positioning block 91, a first movable rod 93 is fixedly connected to the middle part of the first positioning block 91, the first movable rod 93 is movably sleeved with the second water-blocking baffle 72, and the first positioning block 91 is fixedly connected to the second movable sleeve 82;

[0041] The above scheme is adopted: the first movable sleeve 81, the second movable sleeve 82 and the first spring 83 cooperate to make the first telescopic component 8 as a whole telescopic. The first telescopic component 8 is installed at both ends of the water-blocking component 7, which plays a role in limiting the water-blocking component 7. When the water-blocking component 7 rotates to the inside of the placement groove 23, the first telescopic component 8 is gradually shortened as a whole through contact and extrusion with the first roller 92, so that it is located in a compressed state inside the placement groove 23, thereby reducing the overall thickness of the bottom wall body 21.

[0042] like Figure 6 As shown, the sediment cleaning assembly 11 includes a first sediment baffle 111 movably connected to the second connecting block 10, and the end of the first sediment baffle 111 away from the second connecting block 10 is movably connected to the second sediment baffle 112. The first sediment baffle 111 and the second sediment baffle 112 are both arc-shaped and have a first water-permeable hole running through the surface. The tops of the first sediment baffle 111 and the second sediment baffle 112 are symmetrically distributed and run through the top and bottom. The two ends of the cleaning baffle 14 are respectively located in the two arc grooves on the tops of the first sediment baffle 111 and the second sediment baffle 112, and the surface of the cleaning baffle 14 is provided with a second water-permeable hole.

[0043] The above scheme is adopted: the first water permeable holes on the surfaces of the first and second sediment baffles 111 and 112 and the second water permeable holes on the surface of the cleaning baffle 14 can facilitate the passage of water flow and block the sediment, so as to ensure that the sediment is pushed. When the water flow is slow, it will not rotate due to the impact of the bottom water flow. Conversely, when the water flow is slow, it will not bring sediment. When the sediment cleaning component 11 rotates clockwise, after pushing the sediment, the second movable component 13 contacts the telescopic sleeve 16 and under the action of pressure, the second sediment baffle 112 and the end not connected to the first sediment baffle 111 approach each other, thereby squeezing the cleaning baffle 14, so that the cleaning baffle 14 moves outward along the angle formed by the first and second sediment baffles 111 and 112, further pushing the sediment, so that the sediment breaks away from the inner sides of the first and second sediment baffles 111 and 112, and is discharged to the downstream of the river channel during the water flow movement inside the drainage trough 22 to prevent sedimentation.

[0044] like Figure 6 As shown, the second telescopic assembly 12 includes a third movable sleeve 121 fixedly connected to the second connecting block 10, and the end of the third movable sleeve 121 away from the second connecting block 10 is movably sleeved with a fourth movable sleeve 122, and the end of the fourth movable sleeve 122 located inside the third movable sleeve 121 is fixedly connected to the second spring 123, and the end of the fourth movable sleeve 122 away from the third movable sleeve 121 is fixedly connected to the second movable assembly 13, and the second movable assembly 13 includes a second positioning block 131, and the lower end bearing of the outer surface of the second positioning block 131 is connected to the second roller 133, and the middle part of the second positioning block 131 is fixedly connected to the second movable rod 132, the second movable rod 132 is movably sleeved with the second mud and sand baffle 112, and the fourth movable sleeve 122 is fixedly connected to the second positioning block 131;

[0045] By adopting the above-mentioned scheme, the purpose of extension and retraction can be achieved through the design of the third movable sleeve 121, the fourth movable sleeve 122 and the second spring 123, so that when the first mud and sand baffle 111 and the second mud and sand baffle 112 reach the inside of the placement groove 23, the two ends of the second mud and sand baffle 112 that are not connected to the first mud and sand baffle 111 can be gradually approached under the extrusion of the inside of the bottom wall body 21 and the second roller 133, thereby reducing the overall length value of the mud and sand clearing assembly 11, and then reducing the thickness of the bottom wall body 21.

[0046] The working principle and use process of the present invention:

[0047] When the flood season comes, water flows downward along the river channel from upstream and impacts the bottom retaining wall 2. The design of the water blocking component 7 and the sediment clearing component 11 hinders the water flow to a certain extent. In the flood, there is water above and sediment at the bottom. Therefore, the impact force of the upper water flow drives the first connecting component 4 to rotate clockwise, and then drives the second connecting column 5 to rotate clockwise through the movable column 3. The rotation of the first connecting component 4 and the second connecting column 5 can convert the impact force generated by the water flow into a force that drives the first connecting component 4 and the second connecting column 5 to rotate, thereby achieving the effect of reducing the impact force to a certain extent.

[0048] Since the expansion area of the water blocking component 7 is larger than the expansion area of the silt cleaning component 11, and the water blocking component 7 is located above the silt cleaning component 11, the impact force of the water above drives the bottom silt cleaning component 11 to rotate and push the silt, and the arc direction of the silt cleaning component 11 is opposite to the arc direction of the water blocking component 7. The water blocking component 7 can better withstand the impact of water, and the silt cleaning component 11 can better push the silt when it rotates clockwise. By cleaning the design of the baffle 14 and the telescopic sleeve 16, the silt cleaning component 11 can be rotated clockwise. As the needle rotates and pushes the sediment, the second movable assembly 13 contacts the telescopic sleeve 16 and, under the action of pressure, the ends of the second sediment baffle 112 and the first sediment baffle 111 that are not connected approach each other, thereby squeezing the cleaning baffle 14, causing the cleaning baffle 14 to move outward along the angle formed by the first sediment baffle 111 and the second sediment baffle 112, further pushing the sediment, causing the sediment to separate from the inner sides of the first sediment baffle 111 and the second sediment baffle 112, and be discharged to the downstream of the river channel during the water flow in the drainage trough 22 to prevent sedimentation;

[0049] At the same time, the cooperation between the water blocking component 7 and the first telescopic component 8, the mud and sand clearing component 11 and the second telescopic component 12 can reduce the overall length, and thus can move inside the placement groove 23 in a compressed state, such as Figure 5 and Figure 6 As shown on the right, the overall thickness of the bottom retaining wall 2 is reduced;

[0050] At different times, the connecting rope 171 can be retracted and released by starting the driving motor 173 to drive the winding wheel 172 to rotate, thereby driving the height of the first connecting component 4 and the water-blocking component 7. The adjustment during the flood season can adapt to the water surface height. During the non-flood season, the water flow is small and the water flow is slow, and very little sediment is carried because there is no need to drain the sediment. The first water permeable holes on the surfaces of the first sediment baffle 111 and the second sediment baffle 112 and the second water permeable holes on the surface of the cleaning baffle 14 can facilitate the passage of water and will not rotate under the impact of the water flow.
