[0028] The realization, functional characteristics and advantages of the utility model will be further described with reference to the drawings combined with the embodiment. DETAILED DESCRIPTION
[0029] The technical scheme in the embodiment of the utility model will be clearly and completely described in the embodiment of the utility model combined with the drawings, obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by those skilled in the art without creating labor belong to the scope of the utility model protection.

Therefore, the features limited by "first", "second" can be explicitly or implicitly included at least one feature. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, also not within the protection scope required by the utility model.
[0032] In the low-lying area of the city or underground space, it is easy to produce water accumulation, especially in the rainy weather or the place with poor drainage effect, the loss caused by rain flood is great, the subway has large passenger flow, and there is also a safety hazard, so great manpower cost and equipment cost are invested in flood prevention and backflow prevention of the subway.
[0033] The utility model provides a kind of automatic lifting fender 100 to alleviate the above problems, such as Figure 1 As shown, automatic lifting fender 100 includes "U" type base 10, base 10 has two side walls and water storage cavity 11 structure, the length of two side walls is higher than water storage cavity 11 structure, the bottom of base 10 is arranged in the sink of entrance and lower than entrance, drainage hole can be arranged in the bottom wall of base 10, sink is lower than ground, does not affect pedestrian to pass through, two side walls of base 10 are arranged in the two sides of sink, can be hiddenly arranged in entrance or integrally arranged with the wall of entrance, first fender 12 is slidably connected with base 10 and arranged in water storage cavity 11;
[0034] In flood season, first fender 12 is arranged in the underground sink of subway entrance, the top of first fender 12 is flush with ground, and the normal opening of subway station is not affected by the normal entry and exit of passengers;
[0035] In the flood season, water flows into the storage cavity 11 from the opening, and the drain hole drains water at the same time. If the water in the storage cavity 11 does not reach the first water baffle 12 when draining, it means that no rainstorm has occurred. The first water baffle 12 cannot extend into the sink due to insufficient water in the storage cavity 11. When the water inflow speed in the storage cavity 11 is greater than the water outflow speed, it means that the exit has been flooded by rainstorm, and the first water baffle 12 is submerged. Under the buoyancy of water, the first water baffle 12 automatically rises and extends into the sink, blocking the exit, intercepting the floodwater flowing into the subway exit, reducing the loss caused by the floodwater flowing into the subway exit, reducing the probability of risk occurrence, avoiding manual relief of the floodwater, and reducing the maintenance cost of manpower.
[0036] After the flood season, the water flow disperses, and the first water baffle 12 automatically descends after the buoyancy disappears, restoring the state of being hidden in the sink. The exit resumes normal traffic, realizes automatic response to the floodwater flowing phenomenon, does not need to set a motor or other driving equipment, and does not need electricity, is convenient to use, has a simple structure, and improves the safety of the subway.
[0037] The setting of the drain hole ensures that the automatic lifting water baffle 100 can rise to block water in the case of heavy rain or flood, and in the daily state, the automatic lifting water baffle 100 will not affect the normal use of the exit.
[0038] Optionally, the number and height of the first water baffle 12 can be set as needed. In the case of setting one first water baffle 12, the height of the first water baffle 12 is preferably 800 mm. Of course, a second water baffle 13 can also be set, and the heights of the first water baffle 12 and the second water baffle 13 are both 400 mm. Multiple water baffles can also be set, or different heights can be set.
[0039] Preferably, two water baffles are arranged side by side in the storage cavity 11 to cope with the case that the sink of part of the subway exit cannot be dug to 800 mm or deeper, but a higher water baffle is needed. In the case that the sink cannot be dug more than 400 mm due to geological limitations or other factors, the height of the two water baffles is stacked to achieve an 800 mm high water blocking effect when the two water baffles extend into the sink, saving space in the vertical direction. Figure 2 In the case of setting the first water baffle 12 and the second water baffle 13, the second water baffle 13 can also be slidably connected with the base 10. When water flows into the storage cavity 11 from the opening, the second water baffle 13 and the first water baffle 12 rise at the same time, and the maximum rising height of the second water baffle 13 is greater than that of the first water baffle 12. When the second water baffle 13 and the first water baffle 12 both rise to the maximum rising height, the height of the first water baffle 12 and the second water baffle 13 is stacked to block the water flow, achieving the maximum prevention of water flow.
[0040] The first water baffle 12 is raised and lowered by sliding along the first slide rod 16, the first slide rod 16 is arranged on the two side walls of the base 10, the length of the first slide rod 16 exceeds the height of the sink, so that the first water baffle 12 can extend out of the sink to prevent backflow, and the first water baffle 12 can be raised to the maximum height;
[0041] The second water baffle 13 is raised and lowered by sliding along the second slide rod 17, similarly, the second water baffle 13 is raised to the maximum height by sliding along the second slide rod 17, and the length of the second slide rod 17 is greater than the length of the first slide rod 16, so that the sliding distance of the second water baffle 13 is greater than that of the first water baffle 12, and the height of the first water baffle 12 and the second water baffle 13 is stacked, the first slide rod 16 and the second slide rod 17 are arranged to make the first water baffle 12 and the second water baffle 13 rise and fall along the fixed path and realize automatic lifting;
[0042] After the first water baffle 12 and the second water baffle 13 extend out of the sink at the same time, in order to prevent the distance between the first water baffle 12 and the second water baffle 13 from causing water to flow into the water storage cavity 11, the length of the second slide rod 17 is greater than or equal to the sum of the height of the first water baffle 12 and the height of the second water baffle 13, and the first water baffle 12 and the second water baffle 13 are raised to the maximum height, and the water flow is blocked by the sum of the height of the first water baffle 12 and the height of the second water baffle 13.
[0043] The second slide rod 17 is arranged on the two side walls of the base 10 in parallel with the first slide rod 16, so that the first water baffle 12 and the second water baffle 13 are arranged adjacent to each other, the water storage cavity 11 just accommodates the first water baffle 12 and the second water baffle 13, and is flush with the sink in the water storage cavity 11, the gap between the first water baffle 12 and the second water baffle 13 is small, the first water baffle 12 and the second water baffle 13 move independently and do not affect each other, when water accumulation occurs, if the water accumulation flows out of the drain hole normally, the water accumulation in the water storage cavity is very small, the first water baffle 12 and the second water baffle 13 will not float out of the sink, when water flows into the water storage cavity 11, if the drainage speed of the drain hole is less than the water inflow speed of the water storage cavity 11, the water storage cavity 11 reaches a certain water accumulation, the first water baffle 12 and the second water baffle 13 extend out of the sink at the first time to prevent backflow, the water flow flows into the opening of the water storage cavity 11, the first water baffle 12 and the second water baffle 13 rise at the same time, when the flood season ends, the drainage speed is greater than the flood inflow speed, the first water baffle 12 and the second water baffle 13 are lowered.
[0044] Preferably, when the first water baffle 12 and the second water baffle 13 are arranged side by side, the first water baffle 12 is arranged on the outer side away from the subway entrance, and the second water baffle 13 is arranged on the inner side close to the subway entrance, so that the first water baffle 12 and the second water baffle 13 are stable in structure during water blocking.
[0045] Based on the foregoing embodiment, the first sliding rod 16 limits the first water baffle 12 through the first limiting piece 14. Referring to Figure 3 The first limiting piece 14 is sleeved with the first sliding rod 16 at one end, and has a limiting surface with a certain area at the other end. The area of the limiting surface is greater than the area of the first sliding rod 16.
[0046] The second sliding rod 17 limits the second water baffle 13 through the second limiting piece 15. The second limiting piece 15 is sleeved with the second sliding rod 17 at two ends, and has a limiting surface with two certain areas at the other two ends. The area of the limiting surface is greater than the area of the second sliding rod 17. The first limiting piece 14 and the second limiting piece 15 make the first water baffle 12 and the second water baffle 13 cooperate with each other, so that the water blocking height of the first water baffle 12 and the second water baffle 13 is superimposed. The height of the first limiting piece 14 and the second limiting piece can also be adjusted to achieve different water blocking heights.
[0047] Optionally, the sliding mode of the first water baffle 12 and the second water baffle 13 is not limited, and can be achieved by sleeving the first sliding rod 16 and the second sliding rod 17. This mode makes the first water baffle 12 and the second water baffle 13 closely connected with the first sliding rod 16 and the second sliding rod 17.
[0048] In an embodiment, the two side walls of the first water baffle 12 and the two side walls of the second water baffle 13 are both provided with grooves 21, and the first sliding rod 16 and the second sliding rod 17 extend into the grooves 21. The two side walls of the first water baffle 12 and the two side walls of the second water baffle 13 are attached to the two side walls of the base 10. The first sliding rod 16 and the second sliding rod 17 are respectively provided with a plurality of positioning blocks 22. The structure of the grooves 21 and the positioning blocks 22 is adapted to prevent the first water baffle 12 and the second water baffle 13 from tilting during sliding.
[0049] Referring to Figure 4 The automatic lifting water baffle 100 realizes automatic lifting and automatic homing. When the flood recedes, the water in the water storage cavity 11 is discharged from the underground drainage system, and the first water baffle 12 and the second water baffle 13 automatically descend. When the water in the water storage cavity 11 is completely discharged, the first water baffle 12 and the second water baffle 13 both descend to the underground sink until the top of the first water baffle 12 and the second water baffle 13 restores to be flush with the ground. The lifting process is fully automatic, and does not need to rely on electric equipment such as motors for driving. The design is very ingenious, the equipment cost is low, and the labor cost is saved.
[0050] Taking the first water baffle 12 and the second water baffle 13 as examples, each with a height of 400 mm, after water enters the water storage cavity 11, the first water baffle 12 and the second water baffle 13 are simultaneously lifted under the buoyancy of the water; when the depth of the backflowing water is less than 400 mm, one water baffle or two water baffles are used to block the water; when the depth of the backflowing water exceeds 400 mm, the first water baffle 12 is stopped from rising by the first limiting piece 14 when the first water baffle 12 is lifted to a height of 400 mm, and the second water baffle 13 continues to rise, and can be lifted by another 400 mm at most, so that the height of the water blocking is 800 mm, so as to cope with the backflowing water flow; the design of two water baffles can adapt to the sump with different excavation depths at the subway entrance, or can be applied to other entrances; when the height of the sump is limited due to geological conditions or other factors, different numbers of water baffles can be set to be stacked, and the application scenarios are wider.
[0051] The above description is only preferred embodiments of the utility model, and does not limit the patent range of the utility model, and any equivalent structural transformation, direct / indirect application in other related technical fields under the inventive concept of the utility model, or the contents of the utility model specification and drawings are included in the patent protection range of the utility model.
