Description

Technical Field

[0001] The invention relates to the field of urban waterlogging emergency treatment, and in particular to an urban waterlogging emergency treatment device and a treatment method using the device. Background Art

[0002] When heavy rain falls suddenly or the amount of water increases rapidly, low-lying areas such as urban roads, underground garages, and construction areas quickly become flooded. It is impossible to drain the sudden large amount of water in a short time, and even the road manholes may backflow, which means that the water from the manholes flows onto the road surface, causing local waterlogging on the urban road surface. The only water level warning lines marked on the road under the city are unable to provide effective warnings; after heavy rain, the underground garage quickly accumulates water, and the garage water tank cannot quickly drain the water because the drainage pump is damaged or the drainage volume is too low.

[0003] The existing emergency disposal device for urban flooding adopts a manhole cover on the manhole, which can only slow down the backflow speed of water in the manhole but cannot fundamentally prevent the water in the manhole from leaking out, thereby failing to alleviate the safety hazards caused by urban flooding. Summary of the invention

[0004] In order to solve the above technical problems, one of the purposes of the present invention is to provide an emergency disposal device for urban flooding, which can fundamentally prevent the water in the manhole from leaking out, thereby eliminating the safety hazards caused by urban flooding.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A waterlogging emergency disposal device comprises a water-containing cover with an opening at the bottom. The water-containing cover is foldable and can bulge along the direction of water surging in a manhole. The water-containing cover is used to lower the water head line at the location of the manhole.

[0007] Furthermore, the water-containing cover body includes an upper cover body with an opening at the bottom, and the upper cover body includes segmented cover bodies arranged in sequence from bottom to top, and the connection between adjacent segmented cover bodies forms a seamless soft connection.

[0008] Further preferably, the bulging segmented cover body is a truncated cone, and the upper diameter of the segmented cover body decreases from bottom to top.

[0009] Further preferably, adjacent segmented covers are connected via floating rings, and the connection between the segmented covers and the floating rings forms a seamless soft connection;

[0010] An exhaust valve device is arranged inside the floating ring located at the top of the water-containing cover body, and the exhaust valve is seamlessly connected to the floating ring at the top of the water-containing cover body.

[0011] Further preferably, the water-containing cover body further comprises a lower cover body located below the upper cover body, and the bottom of the segmented cover body of the upper cover body is seamlessly connected to the lower cover body.

[0012] Further preferably, the device also includes a base with a water inlet hole, and the base is used to fix the entire water-containing cover body at the location of the manhole, and the lower part of the lower cover body is seamlessly connected to the base.

[0013] More preferably, the top of the lower cover body is provided with an annular connecting section, and the bottom of the segmented cover body located at the lower part of the upper cover body is seamlessly connected to the connecting section;

[0014] The connecting section is provided with a plug hole, and the water-containing cover body also includes a guide rod, which extends from the outside of the upper cover body into the inside of the upper cover body, the outer wall of the guide rod is fitted and connected with the hole wall of the plug hole, and the bottom of the guide rod is connected to the base.

[0015] More preferably, the base comprises a base plate and an inserting tube fixed on the base plate surface, and the inserting tube is located on the inner side of the lower cover, the bottom of the guide rod extends into the inserting tube, and the guide rod can move up and down along the axial direction of the inserting tube; the lower cover is a soft body;

[0016] A water level monitoring component is arranged on the base at a position close to the inserting tube.

[0017] More preferably, a manhole cover is provided at the manhole mouth of the manhole, a water outlet is provided on the manhole cover, and the opening of the base is sleeved on the outside of the manhole cover.

[0018] The second object of the present invention is to provide a method for handling waterlogging using an emergency handling device, wherein the base comprises a first substrate and a second substrate whose surfaces are bonded to each other, and the method comprises the following steps:

[0019] S1, sleeve the whole composed of the first substrate and the second substrate on the ground outside the manhole cover of the manhole, fix it on the ground through a suction cup, and move the guide rod upward to open the lower cover;

[0020] S2, the overflow water in the manhole drives the upper cover body to continue to open step by step along the guide rod to the manhole water head line position.

[0021] S3, the water level monitoring component monitors the water level and uploads the water pressure data and device location data to the management personnel. The management personnel can issue early warnings to the surrounding areas based on the uploaded water level information and location information, forming a complete emergency process

[0022] The beneficial effects of the present invention are as follows:

[0023] (1) When the water level at a high place is higher than the water level at a low-lying place where the manhole is located, the water at the high place flows toward the manhole, causing the water in the manhole to flow outward into the cover body of the present invention, and the foldable cover body begins to prop up upward and bulge.

[0024] Water from a high place enters the cover body of the present invention through the manhole, thereby lowering the water level at the high place, and then lowering the water head line of the entire groundwater where the manhole is located. After the water head line of the entire groundwater is lowered, water from other locations will no longer continue to flow into the manhole, thereby fundamentally stopping the backflow of water in the manhole and eliminating the safety hazards caused by urban waterlogging.

[0025] (2) The floating ring of the present invention can float on the water surface, guiding the entire upper cover body to float on the water surface without the upper cover body being blocked in the lower cover body, so that the water gushing out of the manhole can enter the lower cover body and then enter the upper cover body, thereby further reducing the water head line of the entire groundwater where the manhole is located.

[0026] (3) The top of the lower cover of the software of the present invention is installed on the guide rod, and the guide rod can lift the lower cover upward, so that the lower cover can be fully stretched out to contain the water gushing out from the manhole with the maximum volume, thereby further maintaining the stability of the device.

[0027] (4) The top of the lower cover of the soft body of the present invention is installed on the guide rod, and the guide rod can move up and down along the insertion tube, so that the effective height of the lower cover can be adjusted, so that the effective height of the lower cover can be selected according to the degree of urban waterlogging, that is, the effective height of the entire device can be selected, thereby increasing the applicability of the present invention.

[0028] (5) The manhole cover of the manhole is provided with a water outlet hole, and water gushes out from the water outlet hole. The size of the opening of the base of the present invention is larger than the size of the manhole cover, thereby allowing the base to be sleeved on the outer edge of the manhole cover instead of being installed on the manhole cover, thereby preventing the entire cover from collapsing if the manhole cover is flipped up.

[0029] (6) The present invention installs the water level monitoring component on the base plate, which can accurately monitor the height of the water level in the cover body, so that the operator can easily control whether the height in the cover body reaches the maximum allowable height to prevent the water flow from breaking through the cover body.

[0040] The following is a clear and complete description of the technical solution of the present invention in combination with the embodiments and the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] A waterlogging emergency disposal device comprises a water-containing cover 1 with an opening at the bottom and a base 2, wherein the water-containing cover 1 is sleeved on the outside of the base 2. The following describes each of them separately:

[0042] like Figure 3 As shown, the base 2 includes a second substrate 22 and a first substrate 21 located on the upper surface of the second substrate 22 and forming a detachable structure with the second substrate 22, and the surfaces of the first substrate 21 and the second substrate 22 are attached to each other. The first substrate 21 and the second substrate 22 are provided with coaxial openings, and a suction cup 23 is fixed on the lower surface of the second substrate 22, and the suction cup 23 passes through the second substrate 22 and the first substrate 21, so as to facilitate the application of suction force to the suction cup 23 from the top of the first substrate 21. A vertically arranged insert 24 is fixed on the upper surface of the first substrate 21 and located outside the opening, and all the inserts 24 are distributed in a circular shape, and a connecting plate 25 is fixedly installed on the top of the insert 24, and the top of the insert 24 extends to the top of the connecting plate 25, and a through hole 26 is opened on the surface of the connecting plate 25 to reduce the obstruction of the connecting plate 25 to the water flow, and a water level monitoring component 3 is also fixedly installed on the upper surface of the first substrate 21, and the water level monitoring component 3 is located inside the area surrounded by the insert 24.

[0043] like Figure 1 and Figure 3 As shown, the water-containing housing 1 comprises an upper housing 11 and a lower housing 12 arranged in a vertical direction. The upper housing 11 comprises segmented housings 112 arranged in sequence from bottom to top, and adjacent segmented housings 112 are connected by floating rings 111, and the connection between the segmented housings 112 and the floating rings 111 forms a seamless soft connection. Figure 4 As shown, the bulging segmented cover 112 is a truncated cone, and the upper diameter of the segmented cover 112 decreases from bottom to top. The diameter of the floating ring 111 also decreases from bottom to top.

[0044] The top of the lower cover body 12 is provided with an annular connecting section 121, and the bottom of the segmented cover body 112 located at the lower part of the upper cover body 11 is seamlessly connected to the connecting section 121. The lower part of the guide rod 13 passes through the connecting section 121 and enters the lower cover body 12, and the bottom end of the guide rod 13 is inserted into the insert cylinder 24. The guide rod 13 and the insert cylinder 24 are threadedly connected, and the guide rod 13 can move up and down along the axial direction of the insert cylinder 24, and the guide rod 13 can rotate relative to the connecting section 121, and the guide rod 13 and the connecting section 121 are also seamlessly connected.

[0045] When there is no water in the device, the upper segmented cover body is folded segment by segment onto the connecting rod in the middle of the connecting plate 25, so as to be unfolded and floated segment by segment in time when the manhole 6 overflows.

[0046] The use process of the waterlogging emergency disposal device of the present invention is as follows: when water accumulates in the city, water surges out of the manhole 6, and the first substrate 21 and the second substrate 22 are integrally mounted on the ground 4 outside the manhole cover 5 of the manhole 6, and the two substrates are firmly fixed on the ground 4 by the suction cup 23. Then, the guide rod 13 is moved upward to open the lower cover 12. Since the area surrounded by the guide rod 13 forms a cylinder, the soft lower cover 12 can also form a fixed shape under the action of the guide rod 13. After the water surges into the lower cover 12, it continues to surge upward, forcing the various segmented covers 112 of the upper cover 11 to be propped up and opened in turn, so that the segmented covers 112 of the waterlogging emergency disposal device of the present invention can be extended layer by layer to reach the water head line of the manhole 6. The upper cover 11 of the present invention has only an opening at the bottom and a closed top.

[0047] like Figure 5 As shown, H is the total water head line of the water in the underground space when the manhole 6 in the low-lying area overflows. When the total water head line H is higher than the highest point in the underground space, the water in the underground space is under pressure, and the accumulated water that is not discharged in time will overflow along the manhole 6; when the total water head line H is higher than the ground elevation of the manhole 6, the accumulated water overflows to the ground, and if it is not blocked, it overflows to the area below the height of the flood head line. Figure 5In the figure, it can be seen that water flows toward the manhole 6 with a low water level. The water head line of the water in the underground space where the manhole 6 is located is higher than the surface elevation. The water in the underground space is restricted from flowing out by the waterlogging emergency disposal device. The waterlogging emergency disposal device uses the principle of communicating vessels and prevents the water in the underground space from gushing out through a buoyant cover, thereby effectively solving the problem of urban waterlogging.

[0048] like Figure 6 As shown, the water level monitoring component 3 uploads the water pressure data and device location data to the management personnel while monitoring the water level. The management personnel can issue early warnings to the surrounding areas based on the uploaded water level information and location information, thus forming a complete emergency process.
