[0033] Embodiment 1

[0034] Reference Figures 1-11 , this embodiment provides a self-floating water stop gate, including a base 1, L-shaped fixed side columns 2 are arranged on both sides of the upper end of the base 1, a water storage tank 3 is arranged inside the base 1, a water baffle 4 is arranged in the water storage tank 3, and the water baffle 4 rises and falls with the water level in the water storage tank 3. After rising to the maximum height, it blocks the flow of water. Usually, it is stored in the water storage tank 3, and its upper part is flush with the ground.

[0035] In this embodiment, the main body of the water baffle 4 is made of steel structure. The main part of the steel structure is a sealed box body, which provides less buoyancy after being fully lifted, and mainly provides sufficient water blocking strength. The material of the steel structure part is generally 304 stainless steel, which can greatly improve the service life in the underground humid environment.

[0036] In this embodiment, a self-locking hook 41 is provided on one side of the water baffle 4, and a self-locking groove 6 is provided on the inner wall of one side of the water storage tank 3. The self-locking hook 41 is matched with the self-locking groove 6.

[0037] In this embodiment, a U-shaped sealing strip 43 is installed below the self-locking hook 41.

[0038] In this embodiment, a fixed base 7 is arranged inside the water storage tank 3. The fixed base 7 is fixed on the inner wall of the water storage tank 3 through assembly screws 72, and the front inclined surface of the water baffle 4 is attached to the fixed base 7.

[0039] In this embodiment, a base cover plate 71 is arranged at the upper end of the fixed base 7.

[0040] In this embodiment, the bottom end of the water baffle 4 is detachably connected to a floating box 44 through a card slot 5, and a floating box fixing hole 441 is provided on the floating box 44.

[0041] The floating box 44 provides the main buoyancy for the water baffle 4. The floating box 44 is mainly made of high-strength polypropylene and is added with antioxidants and anti-UV components, which can improve its service life. It can be modularly spliced and is divided into 4 specifications of 1000mm, 500mm, 200mm, and 100mm according to length. Different length combinations are selected according to the width of the on-site aisle, and the suitable water retaining height is 0 - 2000mm.

[0042] In this embodiment, a drainage ditch 9 is further arranged inside the base 1, and the drainage ditch 9 is communicated with the water storage tank 3 through an overflow pipe 8.

[0043] In this embodiment, a drainage ditch cover 91 is arranged at the upper end of the drainage ditch 9.

[0044] In this embodiment, a one-way valve 81 is arranged inside the lower pipe body of the overflow pipe 8. The overflow pipe 8 mainly has 3 ports, namely the lower drainage port in the drainage ditch 9, the upper inlet close to the ground, and the lower water inlet in the water storage tank 3. The setting of the one-way valve 81 enables water to only flow from the water storage tank 3 to the drainage ditch 9 (when the water level does not reach the upper water inlet).

[0045] In this embodiment, a water baffle top cover 42 is arranged at the top end of the water baffle 4. The water baffle top cover 42 is connected to the water baffle 4 through cover plate fixing bolts 422, and a sliding groove 421 is formed on the water baffle top cover 42, and the L-shaped fixed side column 2 can pass through the sliding groove 421.

[0046] In this embodiment, the inside of the water baffle 4 has multiple strengthening structures.

[0047] In another embodiment, the main material of the water baffle 4 is high-strength polypropylene, and the upper water baffle body and the floating box are constructed into an integral body for rotational molding; the same water retaining height is divided into 4 specifications of 1000mm, 500mm, 200mm, and 100mm according to length, and combined according to the required inlet width; each unit is connected by bolts, and the gaps are filled with sealant; the main components are: an integrated body, a U-shaped sealing strip, a cover plate, and a self-locking hook; the main water retaining heights are: 300mm, 60mm, and 1000mm, which are more suitable for water retaining at a lower water level.

[0048] The working principle of the present invention is as follows:

[0049] The water baffle 4 is usually stored in the water storage tank 3. The top cover 42 of the water baffle falls on the rear embedded parts and the fixed base 7, and the main body of the water baffle is suspended under the top cover.

[0050] When there is less rain usually, the drainage capacity of the drainage ditch 9 can meet the drainage requirements, the water level in the drainage ditch 9 will not accumulate too much, will not reach the upper opening of the overflow pipe 8, and will not flow into the water storage tank 3. When there is a small amount of rain during rain, since there is a check valve 81 at the bottom, the water in the water storage tank 3 will flow into the drainage ditch 9, the water storage tank 3 will not accumulate water, and the door panel will not rise.

[0051] When the precipitation exceeds the drainage capacity of the drainage system, the water level in the drainage ditch 9 rises to the upper inlet of the overflow pipe 8 and enters the water storage tank 3 from the upper inlet. Because the water level in the drainage ditch 9 is higher than that in the water storage tank 3, the water level in the water storage tank 3 will continue to rise until it is the same as the water level in the drainage ditch 9 and higher than the upper water inlet. When the water level in the water storage tank 3 rises, the buoyancy force received by the water baffle 4 gradually increases. When it exceeds the self-weight of the water baffle 4, the door panel begins to rise until the self-locking hook 41 of the water baffle 4 fits into the self-locking groove 6, and the front inclined surface of the water baffle 4 is completely attached to the inclined surface of the fixed base 7, and the door panel part can continue to rise. At this time, the upward buoyancy force of the water baffle 4 forces the water baffle 4 to be self-locked between the two inclined surfaces, and the front and rear inclined surfaces will provide horizontal component forces, causing the door panel to move towards the backwater surface direction. At this time, the U-shaped sealing strip 43 on the water baffle 4 is attached to the vertical surfaces of the left and right columns and the rear embedded parts, achieving a sealing effect. The higher the external water level, the greater the buoyancy force received by the water baffle 4, the greater the horizontal component force, and coupled with the horizontal thrust of the water on the door panel, the water baffle will squeeze the sealing strip to fit the sealing surface. That is, the higher the water level, the better the sealing effect.

[0052] Both sides of the water baffle 4 are supported by side columns, and the lower part is self-locked to the front and rear steel structures within the entire water retaining span. The water baffle 4 has sufficient support and will not flip, thus achieving the purpose of water retaining.

[0053] Note: The height of the upper water inlet of the overflow pipe 8 is the lowest starting height, that is, when the external water level reaches the height of the water inlet and can overflow into the water storage tank 3, the final water level in the water storage tank 3 is flush with the external water level. The water level height at this time can provide sufficient buoyancy to lift the water baffle 4 to the maximum height and lock it self-locked, that is, the buoyancy provided at the lowest starting water level is greater than the self-weight of the water baffle 4 and can also provide sufficient self-locking force. The amount of external water is infinite relative to the water storage tank 3, that is, as long as the water level exceeds the upper water inlet of the overflow pipe 8, the water storage tank 3 will definitely be filled.

[0054] After rainfall, the water level in the drainage ditch 9 drops. Since the water storage tank 3 is connected to the drainage ditch 9 and the one-way valve 81 does not prevent the water in the water storage tank 3 from flowing into the drainage ditch 9, the water in the water storage tank 3 will drop together and finally be completely discharged. During this process, the buoyancy of the water baffle 4 gradually decreases, and it will drop with the water level and fall to the bottom.

[0055] The main parameters of the present invention are the water retaining span and the water retaining height:

[0056] The water retaining span ranges from 1 to 10 meters. If it is too small, it cannot be installed. If it is too large, the stability is poor. For spans exceeding 10 meters, segmented water retaining is adopted.

[0057] The maximum water retaining height is 0.3 - 2 meters, and different main body forms are adopted for different heights.

[0058] Due to the different on-site situations and conditions of each installation location, the size of the equipment will be adjusted according to the actual situation.

[0059] Since the present invention requires excavation of a foundation pit, it is more suitable for new buildings. It can be designed into the building construction, or there is an excavable space on the ground of an old building. It is applicable to entrances, buildings, and section rivers that need to be protected. When used for river flood control, the large-span flood control requirements can be completed without manual handling and excessive operations, greatly improving the efficiency. And it is usually located underground, without affecting normal work and passage during normal times.

[0060] The above are only the preferred embodiments of the present invention, and do not limit the implementation manners and protection scope of the present invention. For those skilled in the art, it should be realized that all equivalent replacements and obvious changes made by using the description and illustrations of the present invention should be included in the protection scope of the present invention.
