Description

Technical Field

[0001] The invention relates to the field of flood control equipment, in particular to a water buoyancy wall. Background Art

[0002] Existing flood barriers are categorized into fixed and removable types based on their removable structure. Fixed flood barriers are permanently installed atop the dam, increasing its height and providing superior flood control. While they offer a sturdy structure and effective flood control, their permanent installation occupies space and hinders effective flood control. Temporarily removable flood barriers, on the other hand, require a significant timeframe for installation and removal. The longer the dam, the longer the installation period. This can hinder timely installation during rapidly increasing flood conditions. In some cases, delays in reporting flood conditions can even lead to delays in the organization of installation. Summary of the Invention

[0003] The purpose of the present invention is to solve the above problems and design a water buoyancy wall. The specific design scheme is as follows:

[0004] A water buoyancy wall includes a lifting chamber and a connecting chamber, wherein the lifting chamber and the connecting chamber are installed on a dam body, a floating block is provided in the lifting chamber, and the floating block is a box-shaped structure, a first water pipe is provided in the connecting chamber, a second water pipe is connected between the lifting chamber and the connecting chamber, and a third water pipe and a fourth water pipe are also provided on the side wall of the connecting chamber, wherein the connecting chamber is a vertically placed cylindrical structure, and the function of the connecting chamber is to introduce water into the connecting chamber and identify the water level. When the water level is too high, the water flows into the lifting chamber, and the floating block is lifted up by the buoyancy of the water, thereby achieving the purpose of increasing the height of the water buoyancy wall.

[0005] The lifting chamber has a "U"-shaped cross-section, the floating block is embedded in the lifting chamber and is slidably connected to the lifting chamber, the lower part of the floating block is provided with a protrusion that is an integral structure with the floating block, and the upper part of the lifting chamber is provided with a limit block that is an integral structure with the lifting chamber. When the floating block rises due to the buoyancy of water, the protrusion abuts against the limit block. The function of this design is to prevent the floating block from escaping from the lifting chamber.

[0006] The first water pipe is placed in a vertical direction, and its height is lower than that of the dam body. Its function is to limit the working water level of the lifting chamber, which is the height of the top of the first water pipe.

[0007] The second water pipe connects the lifting chamber and the connecting chamber in a horizontal direction, and the first water pipe connects with the second water pipe, specifically, the bottom of the first water pipe connects with the middle of the second water pipe.

[0008] The third water pipe and the fourth water pipe in the lifting cavity pass through the water-facing surface of the dam body and are connected to the outside, specifically to the water outside the dam body.

[0009] The third water pipe is located above the fourth water pipe, and the fourth water pipe and the second water pipe are located at the same height. The function of the third water pipe is to inject water into the communicating cavity, and the function of the fourth water pipe is to drain water out of the communicating cavity.

[0010] One end of the second water pipe connected to the connecting cavity and one end of the fourth water pipe connected to the external water body are both provided with a one-way valve, the function of the one-way valve is to ensure the stability of the floating block, that is, it will not float due to slight fluctuations in the water body.

[0011] There are multiple floating blocks, which are distributed in a straight line array to form a floating block wall with a row structure. The tops of the multiple floating blocks are connected by connecting plates.

[0012] A switch valve is provided at the bottom of the float, and a pumping hole is provided on the side wall of the lifting chamber. The switch valve and the pumping hole are used for lowering the float when the water level has not dropped. The specific installation structure of the switch valve is that a knob is provided on the top of the float, and the switch valve and the knob are connected by a connecting rod. Specifically, the switch valve is fixedly connected to the bottom of the connecting rod, the knob is threadedly connected to the upper part of the connecting rod, the connecting rod passes through the float, and the switch valve is against the through hole at the bottom of the float.

[0013] Slide grooves for guiding the up and down movement of the floating block are provided on both sides of the lifting cavity. The slide grooves are guide grooves with a radial cross section in a "C"-shaped structure, and both ends of the chain plate are embedded in the slide grooves.

[0014] The water buoyancy wall obtained by the above technical solution of the present invention has the following beneficial effects:

[0015] It is embedded in the dam body when there is no water situation, does not take up space, and does not block the view. When water situation occurs, it automatically floats up based on the buoyancy of water, and flood prevention is timely. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The present invention will be described in detail below with reference to the accompanying drawings.

[0039] A water buoyancy wall includes a lifting chamber 1 and a connecting chamber 2. The lifting chamber 1 and the connecting chamber 2 are installed on a dam body 10. A floating block 3 is provided in the lifting chamber 1. The floating block is a box-shaped structure. A first water pipe 4 is provided in the connecting chamber 2. A second water pipe 5 is connected between the lifting chamber 1 and the connecting chamber 2. The side wall of the connecting chamber 2 is also provided with a third water pipe 6 and a fourth water pipe 7. The connecting chamber 2 is a vertically placed cylindrical structure. The function of the connecting chamber 2 is to introduce water into the connecting chamber 2 and then identify the water level. When the water level is too high, water flows into the lifting chamber 1, and the floating block 3 is lifted up by the buoyancy of the water, thereby achieving the purpose of increasing the height of the water buoyancy wall.

[0040] The lifting chamber 1 has a "U"-shaped cross-section. The floating block 3 is embedded in the lifting chamber 1 and is slidably connected to the lifting chamber 1. The lower part of the floating block 3 is provided with a protrusion 8 which is an integral structure with the floating block 3. The upper part of the lifting chamber 1 is provided with a limit block 9 which is an integral structure with the lifting chamber 1. When the floating block 3 rises due to the buoyancy of water, the protrusion 8 abuts against the limit block 9. The function of this design is to prevent the floating block 3 from escaping from the lifting chamber 1.

[0041] The first water pipe 4 is placed in the vertical direction. The height of the first water pipe 4 is lower than the height of the dam body 10 . Its function is to limit the working water level of the lifting chamber 1 , which is the height of the top of the first water pipe 4 .

[0042] The second water pipe 5 connects the lifting chamber 1 and the connecting chamber 2 in the horizontal direction, and the first water pipe 4 connects with the second water pipe 5 , specifically, the bottom of the first water pipe 4 connects with the middle of the second water pipe 5 .

[0043] The third water pipe 6 and the fourth water pipe 7 of the lifting chamber 1 pass through the water-facing surface 20 of the dam body 10 and are in communication with the outside, specifically with the water body 12 outside the dam body 10 .

[0044] The third water pipe 6 is located above the fourth water pipe 7. The fourth water pipe 7 is located at the same height as the second water pipe 5. The function of the third water pipe 6 is to inject water into the connecting cavity 2. The function of the fourth water pipe 7 is to drain water from the connecting cavity 2.

[0045] Example 1: Mechanism of floating block:

[0046] As shown in the figure, when the water body 12 rises, it is injected into the connecting cavity 2 from the third water pipe 6, and then flows into the lifting cavity 1 through the first water pipe 4 and the second water pipe 5 in sequence, and the floating block 3 is lifted by the buoyancy to achieve the flood prevention function.

[0047] Example 2 Stability of the floating block 3 at low water level 1:

[0048] like Figure 14 、 15 As shown, when the height of the water body 12 floats below the height of the third water pipe 6, due to the one-way valve 11 on the fourth water pipe 7, the water body 12 will not enter the connecting cavity 2 regardless of whether it rises or falls, and the floating block 3 will not float up, thereby ensuring the stability of the floating block when the height of the water body 12 fluctuates, that is, the floating block 3 will not float and fall frequently.

[0049] Example 3 Stability of the floating block 3 at low water level 2:

[0050] like Figure 16 As shown, if the water body has a large fluctuation amplitude, even if the water body is higher than the third water pipe 6, the water will only flow into the connecting cavity 2. As long as it is not higher than the height of the top of the first water pipe 4, it will not flow into the lifting cavity 1, thereby ensuring the stability of the floating block.

[0051] Example 4 Pre-start of water buoyancy wall:

[0052] like Figure 17 As shown, when the water body is higher than the top of the first water pipe 4, based on the principle of the communicating vessel between the water body and the floating chamber 2, the water in the communicating chamber 2 will also be higher than the top of the first water pipe 4, and will flow from the first water pipe 4 and the second water pipe 5 into the lifting chamber 1. At this time, the lifting chamber 1 and the communicating chamber 2 are connected based on the first water pipe 4 and the second water pipe 5 to form a communicating vessel, and the water level in the lifting chamber 1 will also rise rapidly. The buoyancy of the water will lift the floating block 3, that is, when the water level has not yet exceeded the dam body 10, but there is a water situation danger, the floating block 3 will be raised in time.

[0053] Example 5 Stability of the floating block at high water level:

[0054] Water conditions are often accompanied by large fluctuations in the water level. When the float 3 floats up and the water level fluctuates, the float 3 will not fall even if the water level is lower than the third water pipe 6. At this time, the connecting chamber 2 and the water body, and the first water pipe 4 and the lifting chamber 1 form two independent communicating vessels respectively, which do not interfere with each other, thereby ensuring the stability of the float 3.

[0055] Example 6 Resetting of the Floating Block 1:

[0056] When the water situation recedes completely and the water level drops to below the fourth water pipe 7, the one-way valve 11 will not prevent water from flowing from the lifting chamber 1 through the first water pipe 4 into the connecting chamber 2, nor will it prevent the water in the connecting chamber 2 from flowing out of the dam body 10 through the fourth water pipe 7. When the water flows out, the floating block 3 loses its buoyancy and descends.

[0057] Example 7: Resetting of the Floating Block 2:

[0058] For some water conditions, the water needs to recede slowly, but the receding process is relatively gentle, and there is no risk of repeated floating of the water body. At this time, the float 3 can be actively lowered after the water body drops to the height of the water-facing surface of the dam body. Under normal circumstances, the knob 17 is tightened, and the knob 17 and the switch valve 15 clamp the float 3, blocking the through hole 19 below the float 3 to ensure the sealing of the float 3 so that it can float. When the float 3 needs to be reset, loosen the knob 17, and the distance between the knob 17 and the switch valve 15 will increase, leaving a gap to disengage the switch valve 15 from the through hole 19. Water can enter the float 3 through the through hole 19, thereby causing it to lose buoyancy and achieve the purpose of descending.

[0059] Example 8: Resetting of the Floating Block 3:

[0060] When the water level drops below the height of the first water pipe 4, in addition to using the reset method of Example 7, a water pump can be used to pump out the water in the lifting chamber 1 through the pumping hole 16 to reset the float 3. Based on the stability principle of Examples 3 and 5, no new water will be injected into the lifting chamber 1, that is, the float 3 will not rise again. If the reset method of Example 7 is used, the method of this embodiment can also be used to pump out the water in the float 3.

[0061] Example 9 Adjustment of Operation Sensitivity During Installation 1:

[0062] Based on the operating mechanism and stability mechanism in Examples 1-5, the sensitivity of the floating block 3 when it is raised can be adjusted by adjusting the height of the top of the first water pipe, specifically the height difference between the height of the top of the first water pipe and the upper edge of the water-facing surface of the dam body 10. The smaller the height difference, the better the stability of the floating block 3, the less likely the floating block 3 is to be lifted up, but the shorter the reaction time when the floating block 3 is lifted up; the larger the height difference, the worse the stability of the floating block 3, the easier the floating block 3 is to be lifted up, but the longer the reaction time when the floating block 3 is lifted up.

[0063] Example 10 Adjustment of operation sensitivity during installation 2:

[0064] When building a water buoyancy wall, the sensitivity can be increased by increasing the number of lifting chambers and connecting chambers. The more lifting chambers and connecting chambers there are, the more water pipes will be connected, which will enable faster water injection and improve sensitivity.

[0065] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the present invention. Any changes that may be made to certain parts thereof by those skilled in the art all reflect the principles of the present invention and fall within the scope of protection of the present invention.
