The flood control assembly can be detachably installed on the mobile assembly, and the interior of the flood control assembly is hollow and filled with sand and gravel to further improve the water blocking effect, while increasing the weight of the flood control assembly to avoid being washed away by the water flow.

[0023] The strip-shaped sliding groove is a dovetail groove, and the strip-shaped protrusion is correspondingly arranged in a dovetail shape.

[0024] With the above structure, since the strip-shaped sliding groove is a dovetail groove, the sealing performance between the first moving plate and the second moving plate can be further improved. Preferably, sealing strips are provided in the sliding groove and the strip-shaped sliding groove to achieve the best sealing performance.

[0025] The power mechanism includes a rotating motor, a rotating shaft, a rotating disk and a拨动 plate. The rotating motor is fixed on the top plate.

The outer peripheral surface of the positioning ring is in sliding contact with the inner peripheral surface of the guide cylinder. The拨动 plate extends into the space between two adjacent positioning rings to form a linkage mechanism;

[0029] The limiting plate is arranged at the bottom of the rotating column, and a linkage plate is arranged on one side of the moving plate 1 and the moving plate 2 facing the inside of the supporting assembly, and the linkage plate presses the limiting plate to form a linkage mechanism.

[0030] With the above structure, the rotating motor drives the rotating disk to rotate through the rotating shaft, so that the toggle plate drives the positioning ring to move upward, realizing the position adjustment of the rotating column and the limit plate; the limit plate further drives the linkage plate (and other parts of the moving assembly) to move together. Under the action of gravity, the positioning ring presses the shaped positioning piece, and the end of the shaped positioning piece passes through the positioning plate to form a locking mechanism to prevent the rotating lifting mechanism from sliding downward under the action of gravity.

[0031] A rotating hand wheel is arranged on the top of the rotating column, and the rotating hand wheel is located above the guide cylinder;

[0032] The limiting plate is provided with an opening slot for the linkage plate to pass through.

[0033] With the above structure, the outer circumference of the positioning ring is in sliding contact with the inner circumference of the guide cylinder, so that the rotating column and the positioning ring can rotate; the hand wheel is turned to drive the limit plate to rotate through the rotating column; when the opening slot is aligned with one of the linkage plates, the corresponding support plate (and related components) does not rise during the rising process of the limit plate, that is, it can only drive the corresponding one mobile component and flood control component to rise; when the opening slot is not aligned with both linkage plates, the limit plate can drive the corresponding two mobile components and flood control components to rise during the rising process. That is, by rotating and adjusting the direction of the limit plate, the position of the corresponding mobile component and flood control component can be controlled and adjusted to achieve the effect of adjusting the height of the mobile component and flood control component in a partial area.

[0034] The flood control assembly includes a plurality of connecting plates 1 and a plurality of connecting plates 2, the connecting plates 1 and the connecting plates 2 have the same height, two connecting plates 1 and two connecting plates 2 are surrounded by a "mouth" shape and form a receiving space in the middle, and the receiving space is filled with sand and gravel

[0035] An upper end of the connecting plate is provided with an upper plugging groove opening upward, and a lower end of the connecting plate is provided with a lower plugging groove opening downward.

[0036] The lower ends of the two connecting plates are provided with butt joint grooves opening downwards;

[0037] Among them, the connection mechanism of the connecting plate 1 and the connecting plate 2 is:

[0038] The docking groove of the upper connecting plate 2 is inserted into the upper plugging groove of the upper connecting plate 1, and the upper end surface of the connecting plate 2 is flush with the center line of the connecting plate 1;

[0039] The upper end surface of the second connecting plate located at the bottom is inserted into the lower plug-in groove of the first connecting plate located at the top, and the two connecting plates are pressed against each other, and the lower end surface of the second connecting plate is flush with the upper end surface of the first connecting plate located at the bottom;

[0040] The moving plate 1, the moving plate 2 and the bottom plate are all provided with a strip-shaped sliding groove 1 for inserting one side of the connecting plate.

[0041] With the above structure, the flood control components can be spliced ​​quickly, with good stability, and can be moved as a whole without falling apart, with good water-blocking and protective effects. The connecting plates 1 located on the front and rear sides are located at different heights, that is, the contact surface heights between the two adjacent upper and lower connecting plates 1 are different, which is conducive to improving the water-blocking effect, improving the stability of the installation of connecting plate 1 and connecting plate 2, and improving the installation efficiency of connecting plate 1 and connecting plate 2. At the same time, multiple accommodating spaces in the same vertical direction are mutually penetrated, and the multiple accommodating spaces on both sides of connecting plate 2 are relatively independent. The equipment has the best support and accommodating effect for sand and gravel, and is convenient for filling and replacing sand and gravel in the accommodating space according to actual needs. For example, the height of the sand and gravel in the accommodating space is adjusted according to the water level to ensure that the height of the sand and gravel is greater than the water level. One side of the connecting plate is inserted into the movable plate 1, movable plate 2 and the strip slide groove 1 on the bottom plate to further form a sealing structure and improve the water-blocking effect

[0042] The moving assembly includes a water-blocking plate, and the moving plate 1, the moving plate 2 and the bottom plate are all provided with a strip-shaped slide groove 2 for inserting the edge of the water-blocking plate.

[0043] Install the water-blocking plate, and insert the edge of the water-blocking plate into the second strip slide to further form a sealing structure; at the same time, fill sand and gravel between the water-blocking plate and the flood control components to further improve the water-blocking effect of the equipment.

[0044] The locking assembly includes a positioning rod, including positioning blocks 1, 2 and 3 fixed on the positioning rod in sequence, including positioning plates fixed on both ends of the positioning rod, and a positioning column, wherein the upper end and the lower end of the connecting plate 2 are both provided with semicircular grooves, and the positioning rod passes through a through hole formed by the two semicircular grooves being connected;

[0045] On the two adjacent connecting plates 1 at the same level, the connecting plates 2 corresponding to the ends of the two connecting plates 1 are respectively clamped between the positioning blocks 1, 2 and 3 to form a locking mechanism, and the two positioning plates are respectively located in the two accommodating spaces;

[0046] In the same accommodating space, the corresponding two positioning plates are pressed against each other;

[0047] The positioning column is located in the accommodating space, one end of the positioning column is pressed against the moving plate 1 or the moving plate 2, and one end of the positioning column is pressed against the positioning disk in the accommodating space to form a locking mechanism.

[0048] With the above structure, the locking assembly is arranged along the direction in which the connecting plate 1 extends, and is used to position and stabilize the multiple connecting plates 2. The two ends of the locking assembly are pressed against the movable plate 1 and the movable plate 2 by the positioning column to form a locking mechanism to prevent the connecting plate 2 from deforming or moving. In the same accommodating space, the corresponding two positioning plates are pressed against each other to prevent shaking between the multiple positioning rods, and the stabilization effect is better. When the equipment is in use, it is impacted by water flow. When the multiple connecting plates 1 are bent due to force, the connecting plate 1 transmits the impact force to the positioning rod, so that the positioning plates are squeezed against each other. The contact area between the two positioning plates is large, and the structure is stable, thereby avoiding the angle between the two adjacent positioning rods, thereby improving the overall stability of the connecting plate 1 and the connecting plate 2.

[0049] Compared with the existing technology, this water conservancy project flood control slope protection has the following advantages:

[0050] 1. When the water level rises during the flood season, multiple connecting plates 1 and 2 and the baffle are installed on the mobile component, and sand and gravel are filled in the accommodating space, as well as between the flood control component and the baffle; the rotating motor is started to drive the positioning ring to move upward through the toggle plate, and the limit plate drives the corresponding support plate to rise, thereby realizing the overall position increase of the mobile component until the height of the flood control component and the baffle is greater than the water level; then, the bent part of the shaped positioning piece is sleeved on the outer periphery of the rotating column, and the end of the shaped positioning piece passes through the positioning plate. Under the action of gravity, the positioning ring presses the shaped positioning piece, and the end of the shaped positioning piece passes through the positioning plate to form a locking mechanism to prevent the rotating lifting mechanism from sliding downward under the action of gravity.

[0051] 2. The support assembly is installed on the water retaining base, and the two ends of the mobile assembly are slidably set on the two support assemblies. The power mechanism is used to drive the rotating lifting mechanism to move, and the rotating lifting mechanism further drives two or one mobile assembly to rise, thereby completing the position adjustment of the mobile assembly to cope with the phenomenon of rising water levels. That is, you can choose to adjust the height of the mobile assembly in the area where the water level rises, without adjusting the height of all mobile assemblies, which is more flexible to use. The flood control assembly can be detachably installed on the mobile assembly. The interior of the flood control assembly is hollow and filled with sand and gravel to further improve the water blocking effect, while increasing the weight of the flood control assembly to avoid being washed away by the water flow.

[0052] 3. The first moving plate, the second moving plate and the bottom plate form a "C" shape with an upward opening, and a space for placing the flood control component is formed inside. The two sides of the flood control component are fixed to the first moving plate and the second moving plate, and the bottom of the flood control component is fixed to the bottom plate. The inside of the flood control component is filled with sand and gravel, thus forming a waterproof and airtight structure to block the flow of water through, having a very good water blocking effect; the moving component can drive the flood control component to move accordingly to deal with the situation of rising water level.

[0053] 4. The outer peripheral surface of the positioning ring is in sliding contact with the inner peripheral surface of the guiding cylinder, so that the rotating column and the positioning ring can rotate; the rotating handwheel drives the limiting disc to rotate through the rotating column; when the opening groove is aligned with one of the linkage plates, during the rising process of the limiting disc, the corresponding support plate (and related components) does not rise, that is, only one corresponding moving component and the flood control component can be driven to rise; when the opening groove is not aligned with both linkage plates, during the rising process of the limiting disc, two corresponding moving components and the flood control component can be driven to rise. That is, by rotating and adjusting the direction of the limiting disc, the position of the corresponding moving component and the flood control component can be controlled and adjusted to achieve the effect of adjusting the height of the moving component and the flood control component in some areas.

[0054] 5. The flood control component is quickly spliced, has a good stabilizing effect, can move as a whole without falling apart, and has a very good water blocking and protecting effect. The first connecting plates located on the front and rear sides are at different heights, that is, the contact surface heights between two adjacent upper and lower first connecting plates are different, which is beneficial to improving the water blocking effect, beneficial to improving the stability of the installation of the first connecting plate and the second connecting plate, and beneficial to improving the installation efficiency of the first connecting plate and the second connecting plate. The edge of the water separating plate is inserted into the second strip-shaped sliding groove, further forming a sealing structure, and sand and gravel are filled between the water separating plate and the flood control component, further improving the water blocking effect of the equipment.

[0096] When the opening slot 423a is aligned with one of the linkage plates 55, the corresponding support plate 54 (and related components) does not rise during the rising process of the limit plate 423, that is, it can only drive the corresponding one moving component 5 and the flood control component 6 to rise;

[0107] In the present invention, the connection plates 1 61 located on the front and rear sides are located at different heights, that is, the contact surface heights between the two adjacent connection plates 1 61 at the upper and lower sides are different, which is conducive to improving the water blocking effect, the stability of the installation of the connection plates 1 61 and 2 62, and the installation efficiency of the connection plates 1 61 and 2 62. At the same time, it is realized that multiple accommodation spaces 60 in the same vertical direction penetrate each other, and the multiple accommodation spaces 60 on both sides of the connection plate 2 62 are relatively independent, so that the equipment can achieve the best support and accommodation effect for sand and gravel, and it is convenient to fill and replace the sand and gravel in the accommodation space 60 according to actual needs, such as adjusting the height of the sand and gravel in the accommodation space 60 according to the water level to ensure that the height of the sand and gravel is greater than the water level.

[0108] In the present invention, the edge of the connecting plate 1 61 is inserted into the strip-shaped slide groove 1 50a on the moving plate 1 51, the moving plate 2 52 and the bottom plate 53 to further form a sealing structure and improve the water-blocking effect.

[0109] The moving assembly 5 includes a water-blocking plate 56 , and the moving plate 1 51 , the moving plate 2 52 and the bottom plate 53 are all provided with a strip-shaped slide groove 2 50 b for inserting the edge of the water-blocking plate 56 .

[0110] In the present invention, a water-blocking plate 56 is installed, and the edge of the water-blocking plate 56 is inserted into the strip slide groove 2 50b to further form a sealing structure; at the same time, sand and gravel are filled between the water-blocking plate 56 and the flood control component 6 to further improve the water-blocking effect of the equipment.

[0111] The locking assembly 7 includes a positioning rod 70, including a positioning block 1 71, a positioning block 2 72 and a positioning block 3 73 fixed on the positioning rod 70 in sequence, including a positioning plate 74 fixed on both ends of the positioning rod 70, and a positioning column 75, wherein the upper end and the lower end of the connecting plate 2 62 are both provided with a semicircular groove 62b, and the positioning rod 70 passes through a through hole formed by the two semicircular grooves 62b being connected;

[0112] On two adjacent connecting plates 1 61 at the same level, the connecting plates 2 62 corresponding to the ends of the two connecting plates 1 61 are clamped between the positioning blocks 1 71, the positioning blocks 2 72 and the positioning blocks 3 73 to form a locking mechanism, and the two positioning plates 74 are respectively located in the two accommodating spaces 60;

[0113] In the same accommodation space 60, the corresponding two positioning plates 74 are pressed against each other;

[0114] The positioning post 75 is located in the accommodation space 60, one end of the positioning post 75 is pressed against the movable plate 1 51 or the movable plate 2 52, and one end of the positioning post 75 is pressed against the positioning disk 74 in the accommodation space 60 to form a locking mechanism.

[0115] In the present invention, the locking assembly 7 is arranged along the direction in which the connecting plate 1 61 extends, and is used to position and stabilize the multiple connecting plates 2 62. The two ends of the locking assembly 7 are pressed against the moving plate 1 51 and the moving plate 2 52 through the positioning columns 75 to form a locking mechanism to prevent the connecting plate 2 62 from deforming or moving. In the same accommodating space 60, the corresponding two positioning plates 74 are pressed against each other to prevent shaking between the multiple positioning rods 70, and the stabilization effect is better.

[0116] In the present invention, when the equipment is in use and is impacted by water flow, when multiple connecting plates 61 are bent by force, connecting plate 1 61 transmits the impact force to the positioning rod 70, so that the positioning plates 74 are squeezed against each other, the contact area between the two positioning plates 74 is large, and the structure is stable, thereby avoiding the generation of an angle between two adjacent positioning rods 70, thereby improving the overall stability of connecting plate 1 61 and connecting plate 2 62.

[0117] Working principle of the present invention: when the water level rises during the flood season, multiple connecting plates 61 and 62 and the water-blocking plate 56 are installed on the moving component 5, and sand and gravel are filled in the accommodating space 60, as well as between the flood prevention component 6 and the water-blocking plate 56; the rotating motor 411 is started to drive the positioning ring 422 to move upward through the toggle plate 414, and the limit plate 423 drives the corresponding support plate 54 to rise, thereby realizing the overall position rise of the moving component 5 until the height of the flood prevention component 6 and the water-blocking plate 56 is greater than the water level; then, the bent portion of the U-shaped positioning piece 425 is sleeved on the outer periphery of the rotating column 421, and the end of the U-shaped positioning piece 425 passes through the positioning plate 33. Under the action of gravity, the positioning ring 422 presses the U-shaped positioning piece 425, and the end of the U-shaped positioning piece 425 passes through the positioning plate 33 to form a locking mechanism to prevent the rotating lifting mechanism 42 from sliding downward under the action of gravity.

[0118] In the present invention, the support assembly 3 is installed on the water retaining base 1. Both ends of the moving assembly 5 are slidably arranged on the two support assemblies 3. The power mechanism 41 is used to drive the rotation and lifting mechanism 42 to move. The rotation and lifting mechanism 42 further drives two or one moving assembly 5 to rise, thereby completing the position adjustment of the moving assembly 5 to cope with the phenomenon of rising water level. That is, it is possible to select to adjust the height of the moving assembly 5 in the area where the water level rises, without adjusting the height of all the moving assemblies 5, making it more flexible to use. The flood control assembly 6 is detachably installed on the moving assembly 5. The interior of the flood control assembly 6 is hollow to fill with sand and gravel, further improving the water blocking effect and increasing the weight of the flood control assembly 6 to prevent it from being washed away by the water flow.

[0119] In the present invention, the first moving plate 51, the second moving plate 52 and the bottom plate 53 form a "C" shape with an upward opening, and a space for placing the flood control assembly 6 is formed inside. Both sides of the flood control assembly 6 are fixed to the first moving plate 51 and the second moving plate 52, and the bottom of the flood control assembly 6 is fixed to the bottom plate 53. The interior of the flood control assembly 6 is filled with sand and gravel, thereby forming a waterproof and airtight structure to block the water flow from passing through, having a good water blocking effect; the moving assembly 5 can drive the flood control assembly 6 to move along with it to cope with the situation of rising water level.

[0120] In the present invention, sliding grooves 31a are correspondingly formed on the inner wall of the support guide plate 31. The first moving plate 51 and the second moving plate 52 are slidably connected to the support guide plate 31, and the first moving plate 51 is slidably connected to the second moving plate 52. When adjusting the heights of two adjacent moving assemblies 5 to be inconsistent, it can ensure the sealing effect between the first moving plate 51 and the second moving plate 52, as well as ensure the relative displacement between the first moving plate 51 and the second moving plate 52, and can also ensure the sealing effect between the first moving plate 51 and the second moving plate 52 and the inner wall of the support guide plate 31, thereby avoiding water leakage and seepage.

[0121] In the present invention, the outer peripheral surface of the positioning ring 422 is in sliding contact with the inner peripheral surface of the guide cylinder 34, so that the rotating column 421 and the positioning ring 422 can rotate; the rotating handwheel 424 drives the limiting disc 423 to rotate through the rotating column 421; when the opening groove 423a is aligned with one of the linkage plates 55, during the rising process of the limiting disc 423, the corresponding support plate 54 (and related components) does not rise, that is, only one corresponding moving assembly 5 and the flood control assembly 6 can be driven to rise; when the opening groove 423a is not aligned with both of the linkage plates 55, during the rising process of the limiting disc 423, it can drive two corresponding moving assemblies 5 and the flood control assembly 6 to rise. That is, by rotating and adjusting the direction of the limiting disc 423, the position of the corresponding moving assembly 5 and the flood control assembly 6 is controlled and adjusted to achieve the effect of adjusting the heights of the moving assembly 5 and the flood control assembly 6 in a partial area.

[0122] In the present invention, the flood control component 6 can be spliced ​​quickly, has a good stabilization effect, can be moved as a whole without falling apart, and has a good water-blocking and protective effect. The connecting plates 1 61 located on the front and rear sides are located at different heights, that is, the contact surface heights between the two upper and lower adjacent connecting plates 1 61 are different, which is conducive to improving the water-blocking effect, and is conducive to improving the stability of the installation of the connecting plate 1 61 and the connecting plate 2 62, and is conducive to improving the installation efficiency of the connecting plate 1 61 and the connecting plate 2 62. At the same time, it is realized that multiple accommodating spaces 60 in the same vertical direction penetrate each other, and the multiple accommodating spaces 60 on both sides of the connecting plate 2 62 are relatively independent, and the equipment has the best support and accommodating effect on sand and gravel, which is convenient for filling and replacing the sand and gravel in the accommodating space 60 according to actual needs, such as adjusting the height of the sand and gravel in the accommodating space 60 according to the water level to ensure that the height of the sand and gravel is greater than the water level. The water-blocking plate 56 is installed, and the edge of the water-blocking plate 56 is inserted into the strip slide groove 2 50b to further form a sealing structure; at the same time, sand and gravel are filled between the water-blocking plate 56 and the flood control component 6 to further improve the water-blocking effect of the equipment.

[0123] In the present invention, the locking assembly 7 is arranged along the direction in which the connecting plate 1 61 extends, and is used to position and stabilize the multiple connecting plates 2 62. The two ends of the locking assembly 7 are pressed against the moving plate 1 51 and the moving plate 2 52 through the positioning column 75 to form a locking mechanism to prevent the connecting plate 2 62 from being deformed or moved. In the same accommodating space 60, the corresponding two positioning plates 74 are pressed against each other to prevent shaking between the multiple positioning rods 70, and the stabilization effect is better. When the equipment is in use, it is impacted by water flow. When the multiple connecting plates 1 61 are bent due to force, the connecting plate 1 61 transmits the impact force to the positioning rod 70, so that the positioning plates 74 are squeezed against each other. The contact area between the two positioning plates 74 is large, and the structure is stable, thereby avoiding the angle between the two adjacent positioning rods 70, thereby improving the overall stability of the connecting plate 1 61 and the connecting plate 2 62.
