Description

Technical Field

[0001] The utility model relates to the field of water conservancy projects, and particularly to a diversion type flood control dike for water conservancy projects. Background Technique

[0002] Traditional flood control dikes mainly rely on the height and stability of the dike body to block floods. However, in some extreme situations, such as heavy rain and flash floods, traditional flood control dikes may not be able to withstand the huge flood pressure, resulting in the rupture or breach of the dike body. Therefore, it is necessary to improve the traditional flood control dike to enhance its flood control ability.

[0003] The patent with the publication number CN112523179B discloses a flood discharge device for water conservancy flood control projects and its usage method. When it is necessary to move the sliding door upward, the air compressor can be used to inflate the inflatable airbag. After the inflatable airbag is inflated, under the buoyancy of the water flow inside the waterproof dam, an upward acting force is given to the sliding door. After this acting force is combined with the acting force brought by the rotating screw when rotating, people can more easily complete the upward movement operation of the sliding door. When it is necessary to control the sliding door to descend, all the gas in the inflatable cylinder is pumped out, and then the sliding door can be lowered by rotating the screw. Its operation is simple, convenient and fast, further improving the usage effect of the present invention.

[0004] When the sliding door is submerged in the water body, due to the pressure of the water body, a relatively large acting force is required to move the sliding door upward. The airbag can provide an upward acting force to the sliding door to reduce the additional acting force applied when the sliding door slides upward. However, the acting force provided by the airbag fails to be effectively converted and cannot provide an acting force greater than the buoyancy of the water body of the airbag, resulting in a small mechanical advantage of the airbag.

Detailed implementation manners

[0040] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0041] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0042] Refer to Figures 1-5, the present utility model provides a diversion type flood control dike for water conservancy projects, which includes a dike main body 1, a discharge pipe 2, a gate plate 3, a lifting assembly, a floating box 4 and a lever assembly. Among them, a discharge hole is penetrated and arranged in the dike main body 1, and a discharge pipe 2 is installed in the discharge hole. The discharge pipe 2 is used to connect the inner side and the outer side of the dike main body 1 to achieve the flood discharge effect. A gate plate 3 and a lifting assembly are arranged in the dike main body 1. The lifting is used to drive the gate plate 3 to lift and lower to open and close the discharge pipe 2. When the gate plate 3 moves upward, the discharge pipe 2 is opened. When the gate plate 3 moves downward to the bottom end, the discharge pipe 2 can be closed in Shixing County. The floating box 4 is slidably connected to the dike main body 1 and is connected to the gate plate 3 through a lever assembly to provide an upward acting force on the gate plate 3, and this acting force is greater than the buoyancy force received by the floating box 4. The floating box 4 is preferably a stainless steel hollow floating box 4, and the side wall is made of a hollow closed structure of stainless steel material, and its overall density is less than the density of water.

[0043] Preferably, the present utility model further includes a hollow chamber. The hollow chamber is inside the dike main body 1. The upper end of the hollow chamber penetrates the dike main body 1, and the hollow chamber is communicated with the discharge hole. A shell 5 is fixedly connected inside the hollow chamber. The horizontal two ends of the shell 5 are respectively communicated with the two discharge pipes 2. A drain hole 6 is arranged inside the shell 5, and a gate plate 3 is slidably connected along the vertical direction. The gate plate 3 selectively closes the drain hole 6. When the water level exceeds the lowest end of the inner wall of the discharge pipe 2, by sliding the gate plate 3 to open the drain hole 6, the water in the dike main body 1 can be discharged through the discharge pipe 2 and the drain hole 6. On the contrary, by sliding the gate plate 3 to close the drain hole 6, the water in the dike main body 1 can be blocked by the gate plate 3 and cannot pass through the discharge pipe 2, so that the water is intercepted inside the dike main body 1.

[0044] Preferably, the lever assembly includes a support rod 7, a first connecting rod 8 and a second connecting rod 9. Among them: the support rod 7 is located above the gate plate 3, and the support rod 7 is fixedly connected to the inner side wall of the shell 5; one end of the first connecting rod 8 is rotatably connected to the upper end of the gate plate 3, and the other end of the first connecting rod 8 is rotatably connected to the middle part of the second connecting rod 9; one end of the second connecting rod 9 is rotatably connected to the support rod 7, and the other end of the second support rod 7 is connected to the floating box 4.

[0045] When the floating box 4 receives the buoyancy force of water, the floating box 4 provides an upward supporting force on the other end of the second support rod 7. Since the moment of the floating box 4 is greater than the moment of the first connecting rod 8, the upward acting force received by the gate plate 3 is greater than the buoyancy force of the floating box 4, so that the upward acting force on the gate plate 3 can be increased.

[0046] Specifically, the second connecting rod 9 is in an inverted L shape, including a short rod and a long rod that are perpendicular to each other. The short rod and the long rod are connected or integrally formed. One end and the middle part of the long rod are rotatably connected to the support rod 7 and the other end of the first connecting rod 8 respectively. The short rod is provided with a first slide groove 10, and a first sliding rod 11 is slidably connected to the first slide groove 10; a slide rail 12 is slidably connected to the lower surface of the buoyancy box 4, and a second slide groove 13 is provided on the slide rail 12, and the first sliding rod 11 is slidably connected to the second slide groove 13.

[0047] A plurality of second sliding rods 14 arranged in the vertical direction are fixedly connected in the shell 5 , the buoyancy box 4 is slidably connected to the second sliding rods 14 , and a movable notch 15 is arranged on one side of the buoyancy box 4 close to the second connecting rod 9 .

[0048] When the gate plate 3 is at the lowest position, the gate plate 3 blocks the drainage hole 6. At this time, the first sliding rod 11 is located at the side of the first sliding groove 10 away from the housing 5. Figure 3 In the embodiment, the first sliding rod 11 is located at the leftmost side of the first slide groove 10, and the first sliding rod 11 is located at the side of the second slide groove 13 close to the second connecting rod 9, that is, the first sliding rod 11 is also located at the rightmost side of the second slide groove 13. When the gate plate 3 moves upward, the first sliding rod 11 slides on the first slide groove 10 and the second slide groove 13 at the same time, and synchronously, the second connecting rod tilts toward the notch, and then tilts away from the notch, so that the gate plate 3 and the drainage hole 6 are staggered.

[0049] In addition, the utility model is further provided with a vent pipe 16, one end of which passes through the dam body 1, and the other end passes through the shell 5, and the top of the outer wall of the vent pipe 16 is flush with the inner surface of the top plate of the shell 5. The vent pipe 16 can make the air pressure inside the shell 5 equal to that outside the dam body 1, so that water can enter the shell 5 easily.

[0050] The lifting assembly includes a threaded rod 17 and a hand wheel 18. The lower end of the threaded rod 17 is fixedly connected to the upper end of the gate plate, and the upper end of the threaded rod 17 is arranged through the dam body 1. The hand wheel 18 is rotatably mounted on the top plate of the housing 5, and the hand wheel 18 is threadedly connected to the threaded rod 17. By rotating the hand wheel 18, the threaded rod 17 can be raised or lowered, thereby driving the gate plate 3 to rise or fall.

[0051] The inner wall of the housing 5 is fixedly connected with a sliding baffle 19, which is in a "凵"-shaped structure. The sliding baffle 19 is slidably connected to the gate plate 3, and the surrounding side walls of the gate plate 3 are fixedly connected with waterproof rubber strips (not shown in the figure). The waterproof rubber strips and the sliding baffle 19 are used to selectively close the drainage hole 6.

[0052] To prevent the gate plate 3 from not falling in place when the valve plate 3 closes the drain hole 6, the present utility model is provided with a pedestal chamber 20 on the gate plate 3; a lifting table plate 21 is slidably connected in the pedestal chamber 20. The lifting table plate 21 is cylindrical and has an open lower surface. The lifting table plate 21 is also slidably connected to the bottom chute of the pedestal chamber 20, and the lifting table plate 21 selectively abuts against the lower surface of the gate plate 3; a plurality of compression springs 22 are arranged along the width direction of the gate plate 3, and the compression springs 22 are buckled at the lower end of the lifting table plate 21. The two ends of the compression springs 22 are respectively connected to the bottom surface of the pedestal chamber 20 and the lifting table plate 21. When the gate plate 3 closes the drain hole 6, the lower end of the gate plate 3 abuts against the upper surface of the lifting table plate 21 to improve the sealing effect between the gate plate 3 and the housing 5.

[0053] To limit the upward movement of the gate plate 3, the present utility model is further provided with a limit block 23. The limit block 23 is fixedly connected to the inner surface of the housing 5. The limit block 23 is located at the upper end of the gate plate 3 and is used to limit the upward movement of the gate plate 3.
