[0015] In summary, the present application includes at least one of the following beneficial technical effects: 1. The construction of the embankment section is carried out in the corresponding section of the river. Then, before the flood season comes, the flood control box is hoisted into the embankment section by hoisting tools and filled layer by layer with different models according to the requirements. During the rising water level, water continuously flows into the flood control box to increase the weight of the flood control box. The flood control box improves the stability of its position through the block and the baffle of the flood control box below, so that the flood control box will not be washed away by water while forming a dam. At the same time, the flood control box can also control the amount of water flowing downstream through the drainage pipe. After the flood season, the flood control box can be removed to maintain the normal flow of the river; 2. The setting of the water inlet and drainage holes of the flood control box in the middle of the bottom layer can effectively reduce the pressure of the bottom flood control box, and at the same time enable the upstream water to maintain an appropriate amount of flow to the downstream, without completely blocking the river channel; 3. The lifting device of the crane is fixed to the top frame, and then the main board is controlled to move to the top of the flood control box. During the downward movement of the main board, the sliding rod abuts against the top of the flood control box and continuously moves upward under the gravity of the main board, so that the switching column moves upward, the arc-shaped switching plate abuts against the arc-shaped inclined plate and drives the switching wheel to rotate, and then the lifting rod is driven to move to the position abutting against the side wall of the flood control box through the trigger and the sliding plate. Then the crane drives the lifting device upward, and the lifting rod is located in the lifting groove to drive the flood control box to move upward and move. In the process of placing the flood control box into the embankment section, the sliding rod abuts against the top of the flood control box again and drives the switching wheel to rotate, so that the sliding plate is reset, and then the flood control box will not be lifted up during the upward movement of the main board, thereby improving the efficiency of driving the flood control box to move; 4. During the resetting process of the switching column, the inner folding plate pops out. When the switching column moves up again, the inner folding plate first contacts the arc-shaped inclined plate, thereby stably driving the switching wheel to rotate next time. The inner folding plate can be rotated into the inner folding groove after contacting the side wall of the arc-shaped inclined plate, without affecting the rotation angle of the switching wheel. 5. When it is necessary to lift the flood prevention box in the water, first open the drainage pipe of the flood prevention box, and then install the fixing bolt on the first connecting rod. In the process of lifting the flood prevention box, due to the traction of the traction rope, the first connecting rod and the second connecting rod on the water inlet side cannot be fully unfolded, thereby causing the flood prevention box to tilt toward the drainage pipe, thereby improving the efficiency of water discharge in the flood prevention box.

[0018] The following is combined with Figure 1-7 This application is described in further detail. Example

[0019] Example 1 of the present application discloses a flood prevention and water retaining facility.

[0020] refer to Figure 1 and Figure 2 , the flood prevention and water retaining facilities include a dike section 1 and a flood prevention box 2. The dike section 1 is set in the river channel, and is a structure formed by pouring concrete in a steel frame. The side walls on both sides are stepped and have the same layer steel. A plurality of blocks 11 are arranged on the inner bottom wall of the dike section 1. There are multiple flood prevention boxes 2 and they are divided into multiple models. The different models only differ in the horizontal length. The flood prevention boxes 2 are made of metal, and in this embodiment they are made of stainless steel. The height of the flood prevention box 2 is the same as the step height of the dike section 1. In this embodiment, there are three types of flood prevention boxes 2, and the dike section 1 is divided into three layers.

[0021] A plurality of water inlet holes 21 are provided on the top of the upstream portion of the flood-proof box 2, and a drain pipe 22 with a valve is connected to the bottom of the side wall facing downstream. A baffle plate 24 is fixedly provided at the top of the flood-proof box 2 near the drain pipe 22, and lifting ears 25 are provided on the tops of both sides of the two side walls facing upstream and downstream. The flood-proof box 2 is laid in the embankment section 1, and the flood-proof boxes 2 in the embankment section 1 of the same layer are of the same model, and the end faces facing upstream are flush. The flood-proof box 2 can cover the stepped layers of the embankment section 1, and the horizontal length of the flood-proof box 2 decreases layer by layer from bottom to top. The baffle plate 24 of the lower flood-proof box 2 abuts against the side wall of the upper flood-proof box 2, and the side wall of the lowest flood-proof box 2 abuts against the block 11. The upper flood-proof box 2 and the lower flood-proof box 2 are arranged alternately. The water inlet holes 21 of the flood-proof box 2 in the middle of the lowest layer are all over the end faces facing upstream. The end surface of the flood prevention box 2 in the middle of the lowest layer facing downstream has no drainage pipe 22, and is provided with a drainage hole 23 opposite to the water inlet hole 21 area.

[0022] The implementation principle of Example 1 of the present application is as follows: the upstream river gate is closed in advance, and the construction of the dike section 1 is carried out at the corresponding position of the river. When the flood season comes, the upstream river gate is closed to reduce the amount of water in the river, and then the flood control box 2 is placed layer by layer in the corresponding position of the dike section 1 to fill it. Then the gate is opened, and during the process of rising water level, water continuously enters the flood control box 2 through the water inlet 21, and increases the weight of the flood control box 2, thereby improving the stability of the flood control box 2 in the dike section 1. The block 11 abuts against and intercepts the side wall of the bottom flood control box 2, and the upper flood control box 2 is abutted against and intercepted by the baffle 24 of the lower flood control box 2, so that when the water flow gives downward pressure, the position of the flood control box 2 can be kept stable. The setting of the flood control box 2 in the middle of the bottom layer can reduce the pressure of the bottom flood control box 2, so that part of the water flows downstream to maintain the flow of the river. The drainage pipe 22 can be selectively opened to control the amount of water flowing downstream, and the water in the flood control box 2 can be discharged when the flood control box 2 is disassembled. By temporarily setting up the flood control box 2 to form a flood control dam during the flood season, the pressure on the downstream water conservancy facilities can be effectively reduced, and the probability of flood disasters in the downstream can be reduced. At the same time, it can also be dismantled after the flood season ends without affecting the normal flow of the river. Example

[0023] Embodiment 2 of the present application discloses a lifting device for flood control and water retaining facilities, which is used for quickly lifting the flood control box 2 .

[0024] refer to Figure 3 , Figure 4 and Figure 5The lifting device of the flood control and water retaining facility includes a main board 3, a top plate 8, a switching wheel 4 and a sliding plate 6. The top frame is fixed on the upper surface of the top plate 8, and a sling hole 81 for the crane sling to extend into is provided in the middle position of the upper surface of the top frame, and the top plate 8 is provided with a mounting assembly 9 for fixing the crane sling on the top frame. A switching cavity 31 is provided in the middle position of the main board 3, and the switching wheel 4 is rotatably connected to the inner top wall of the switching cavity 31. The switching wheel 4 is a diamond-shaped cam, which is divided into a long end and a short end. The main board 3 is provided with a trigger groove 34 connected to the switching cavity 31 on both sides of the switching cavity 31, and the bottom of the trigger groove 34 is opened. The main board 3 is provided with a sliding cavity 35 on both sides of the switching cavity 31, and the sliding cavity 35 is connected to the trigger groove 34.

[0025] Combination Figure 7 The sliding plate 6 is slidably connected in the sliding cavity 35, and an adjusting plate 66 is inserted into the side wall of the sliding plate 6. A trigger plate 661 is fixedly provided at the end of the adjusting plate 66, and the trigger plate 661 is located in the trigger groove 34. A second spring 64 is fixedly provided on the inner wall of the sliding cavity 35, and the other end of the second spring 64 is fixedly connected to the sliding plate 6. The second spring 64 makes the trigger plate 661 always press against the switching wheel 4.

[0026] A plurality of positioning slots 662 are provided at the bottom of the adjustment plate 66, three in this embodiment. A positioning hole 65 that can communicate with the positioning slot 662 is provided at the bottom of the sliding plate 6, and the positioning hole 65 is threadedly connected with an adjusting bolt 67. When the positioning hole 65 is located in different positioning slots 662, the lifting rod 63 can be in the lifting slot 251 of the lifting ear 25 of the flood control box 2 of different sizes. The adjustment plate 66 is engraved with marking lines 663 on both sides of the positioning hole 65. When the marking lines 663 are directly opposite to the sliding plate 6, the positioning hole 65 is connected with the corresponding positioning slot 662. An extension bar hole 351 is provided at the bottom of the sliding cavity 35 near the two ends of the sliding plate 6, and a first connecting rod 61 is rotatably connected to the bottom of the sliding plate 6, and the first connecting rod 61 extends from the extension bar hole 351. The bottom end of the first connecting rod 61 is rotatably connected to the second connecting rod 62, and the bottom ends of the two second connecting rods 62 are fixedly connected to the same lifting rod 63. Torsion springs are provided at the two rotation axes of the first connecting rod 61, so that the first connecting rod 61 and the second connecting rod 62 form an acute angle toward the center of the main board 3. The top rotation axes of the two second connecting rods 62 on the same side are rotatably connected to the same reinforcing rod 611, which is parallel to the lifting rod 63.

[0027] A lifting groove 251 in which the lifting rod 63 is completely located is provided at the bottom of the lifting ear 25 of the flood prevention box 2 near the flood prevention box 2. A switching assembly 5 for controlling the switching wheel 4 to rotate 90° is arranged in the main board 3. After the switching wheel 4 rotates, the end point abuts against the trigger plate 661. The difference in the distance between the two end points of the switching wheel 4 and its own center is h, and h is not less than the horizontal length of the lifting ear 25. When the long end of the switching wheel 4 abuts against the trigger plate 661, the lifting rod 63 is located on both sides of the lifting ear 25; when the short end of the switching wheel 4 abuts against the trigger plate 661, the lifting rod 63 is pressed against the side wall of the flood prevention box 2. A traction assembly 7 for limiting the opening angle of the first connecting rod 61 and the second connecting rod 62 is arranged between the second connecting rod 62 and the first connecting rod 61 on the side close to the water inlet hole 21.

[0028] After the crane's sling is fixed to the top frame, the crane's boom is located between the vertical planes where the axes of the two lifting rods 63 are located.

[0029] The crane's sling is fixed to the top frame by the installation assembly 9, and then the main board 3 is moved to the top of the flood control box 2 by the crane, and the main board 3 is lowered so that the lifting rod 63 is located on both sides of the lifting lug 25, and the switching wheel 4 is driven to rotate by the switching assembly 5, and the sliding plate 6 slides through the contact relationship between the trigger plate 661 and the switching wheel 4, so that the lifting rod 63 is pressed against the side wall of the flood control box 2. Then the main board 3 moves upward, and the lifting rod 63 is located in the lifting groove 251, and the flood control box 2 is gradually lifted as the main board 3 moves upward, and the first connecting rod 61 and the second connecting rod 62 are rotated to the stretched state. By controlling the rotation of the crane, the main board 3 moves the flood prevention box 2 to the top of the embankment section 1 and starts to lower it. After the main board 3 is lowered to the bottom of the flood prevention box 2 and contacts the flood prevention box 2 or the embankment section 1, the first connecting rod 61 and the second connecting rod 62 start to rotate and reset, and the switching wheel 4 is driven to rotate again through the switching assembly 5, so that the trigger plate 661 abuts against the long end of the switching wheel 4, pushing the sliding plate 6 backward to reset, and then the lifting rod 63 is located on both sides of the lifting ear 25, and then the main board 3 moves up to realize the bottom installation of the flood prevention box 2.

[0030] The setting of the connecting rod can effectively improve the connection strength and rotation stability of the first connecting rod 61 and the second connecting rod 62. The adjusting rod can adjust the position between the trigger plate 661 and the sliding rod 51 by adjusting the bolt 67 in different positioning grooves 662, so that three different sizes of flood control boxes 2 can be stably hoisted and moved.

[0031] When the flood prevention box 2 needs to be disassembled from the embankment section 1, the drainage pipe 22 of the flood prevention box 2 is first opened, and the opening angle between the first connecting rod 61 and the second connecting rod 62 on the side of the water inlet hole 21 is limited by the traction assembly 7. Then, the main board 3 is lowered above the flood prevention box 2 and moved downward. In the process of lifting the flood prevention box 2, since the first connecting rod 61 and the second connecting rod 62 on the side of the water inlet hole 21 are not fully unfolded, the flood prevention box 2 is tilted toward the drainage pipe 22, so that the water in the flood prevention box 2 can be easily discharged.

[0032] The installation orientation of the lifting device and the main board 3 can enable the crane to drive in along the lanes on both sides of the river. The truck equipped with the flood prevention box 2 also drives in together, and the crane can conveniently install and dismantle the flood prevention box 2 on the roads on both sides of the river. By moving the flood prevention box 2 in this way, the efficiency of installing and dismantling the flood prevention box 2 can be effectively improved, and the steps of fixing and dismantling the lifting device and the flood prevention box 2 by people are reduced.

[0033] refer to Figure 5 and Figure 6 The switching assembly 5 includes a sliding rod 51, a switching column 52 and an arc-shaped switching plate 53. A switching groove 41 is provided in the middle of the lower surface of the switching wheel 4, and four arc-shaped inclined plates 42 are provided on the inner wall of the switching groove 41. The four arc-shaped inclined plates 42 are equidistantly distributed around the central axis of the switching wheel 4, and the side walls abut against each other. A sliding groove 32 is provided at the bottom of the switching cavity 31, a sliding hole 321 is provided at the bottom of the sliding groove 32, and a spring cavity 33 is provided at the top of the switching cavity 31. The switching column 52 is vertically slidably connected in the sliding groove 32 and the switching groove 41. There are four arc-shaped switching plates 53, which are fixed on the circumferential outer wall at the top of the switching column 52. The four arc-shaped switching plates 53 are equidistantly distributed around the central axis of the switching wheel 4. The arc-shaped switching plate 53 can abut against the corresponding arc-shaped inclined plate 42 and drive the switching wheel 4 to rotate 90°. An inner folding groove 521 is provided at the top of the circumferential side wall of the switching column 52 and on one side of the top of the arc-shaped switching plate 53. The inner wall of the inner folding groove 521 is rotatably connected with an inner folding plate 5211. A torsion spring is provided between the inner folding plate 5211 and the inner folding groove 521 to enable the inner folding plate 5211 to rotate out. The top of the inner folding plate 5211 is an inclined surface that can be connected with the top of the arc-shaped switching plate 53. The inner folding plate 5211 can abut against the side wall of the arc-shaped inclined plate 42 and completely rotate into the inner folding groove 521. The sliding rod 51 is fixed at the bottom end of the switching column 52 and extends from the sliding hole 321. The sliding rod 51 cannot rotate relative to the sliding hole 321. A connecting hole 43 is formed at the top of the switching slot 41 , a contact rod 522 extending into the spring cavity 33 is fixedly provided at the top of the switching column 52 , a first spring 331 is fixedly provided on the top wall of the spring cavity 33 , and a reset plate 332 is fixedly provided at the bottom end of the first spring 331 to be tightly pressed against the contact rod 522 .

[0034] During the downward movement of the main board 3, after the lifting rod 63 is located on both sides of the lifting lug 25, the sliding rod 51 abuts against the top of the flood control box 2 again and moves upward under the gravity of the main board 3. The upward movement of the sliding rod 51 drives the switching column 52 to move upward, thereby driving the arc-shaped switching plate 53 to abut against the arc-shaped inclined plate 42, and driving the switching wheel 4 to rotate 90° through the contact of the inclined surface, thereby switching the position of the sliding plate 6. During the resetting process of the switching column 52, the arc-shaped inclined plate 42 is separated from the inner folding plate 5211, and then the inner folding plate 5211 pops up and faces the arc-shaped inclined plate 42. When the switching column 52 moves upward again, the inner folding plate 5211 first abuts against the arc-shaped inclined plate 42, driving the switching wheel 4 to rotate, and then the arc-shaped switching plate 53 abuts against the arc-shaped inclined plate 42 again. When the inner folding plate 5211 abuts against the side wall of the arc-shaped inclined plate 42, it will rotate into the inner folding groove 521. Therefore, the switching column 52 can stably drive the switching wheel 4 to rotate 90° each time it moves upward.

[0035] refer to Figure 7 The traction assembly 7 includes a traction rope 71 and a fixing bolt 72. The traction rope 71 is tied to two second connecting rods 62 near the water inlet hole 21. The fixing bolt 72 is tied to the other end of the traction rope 71. The fixing bolt 72 can be threadedly connected to the first connecting rod 61. When the traction rope 71 is straightened, an obtuse angle is formed between the first connecting rod 61 and the second connecting rod 62.

[0036] When the flood prevention box 2 needs to be taken out from the embankment section 1, the fixing bolt 72 is first threadedly connected to the first connecting rod 61. Then, during the process of lifting the flood prevention box 2, due to the traction of the traction rope 71, the first connecting rod 61 and the second connecting rod 62 on one side of the water inlet hole 21 cannot be fully unfolded, so that the flood prevention box 2 remains in a tilted state when lifted, which facilitates the discharge of water in the flood prevention box 2.

[0037] refer to Figure 4 The mounting assembly 9 includes a top tightening plate 91, a mounting plate 92 and a fixing plate 93. There are four top tightening plates 91, which are fixedly mounted on the top of the top frame and located at the four corners of the hanger hole 81. The mounting plate 92 is fixed on the upper surface of the top tightening plate 91, and screw holes are provided on both the mounting plate 92 and the fixing plate 93. An abutment frame 36 abutting against the bottom end of the hanger is fixed on the top of the main board 3, and a lifting hole 361 is provided on the upper surface of the abutment frame 36 for the hook of the crane hanger to extend into. The fixing plate 93 is located above the mounting plate 92, and the fixing plate 93 is provided with bolts that can be threadedly connected to the fixing plate 93. The top tightening plate 91 is threadedly connected with bolts for abutting against the side wall of the hanger.

[0038] After the sling is put into the sling hole 81, the sling is pressed against the abutment frame 36, and the hook is located in the sling hole 361. Then the side wall of the sling is pressed against by bolts, and finally the fixing plate 93 and the mounting plate 92 are installed to fix the sling and the top frame.

[0039] The width of the main board 3 is the same as that of the flood prevention box 2. According to the construction requirements, the main board 3 can be arranged in parallel in multiple pieces, and multiple flood prevention boxes 2 can be hoisted at the same time.

[0040] The implementation principle of the second embodiment of the present application is as follows: after fixing the top frame and the hanger, the main board 3 is moved to the top of the flood box 2, so that the main board 3 moves down. The lifting rod 63 is located on both sides of the lifting ear 25, and then the sliding rod 51 abuts against the top of the flood box 2, the switching column 52 moves up and makes the arc switching plate 53 abut against the arc inclined plate 42 and drives the switching wheel 4 to rotate, and the abutment between the switching wheel 4 and the trigger plate 661 makes the sliding plate 6 slide, and then the lifting rod 63 moves to the position of abutting against the side wall of the flood box 2. During the lifting process of the lifting rod 63, the lifting rod 63 is located in the lifting groove 251 and drives the flood box 2 to move. After the crane moves the flood box 2 to the position where it needs to be lowered, the main board 3 is lowered, so that the sliding rod 51 abuts against the top of the flood box 2 and moves up, and the switching wheel 4 is driven to rotate again, so that the sliding plate 6 is reset, and the lifting rod 63 is located on both sides of the lifting ear 25, so as to realize the rapid lowering and installation of the flood box 2.

[0041] When the flood prevention box 2 needs to be removed from the embankment section 1, the drainage pipe 22 of the flood prevention box 2 is first opened, and then the fixing bolt 72 is installed on the first connecting rod 61, and the main board 3 is located above the flood prevention box 2. When the lifting rod 63 drives the flood prevention box 2 to move upward, the flood prevention box 2 is pulled upward by the traction rope 71, and the water inside can be easily discharged. Then the flood prevention box 2 is placed on a truck to achieve rapid removal of the flood prevention box 2.

[0042] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
