[0033] Example 1

[0034] refer to Figure 1-11 This embodiment provides a self-floating water gate, including a base 1. L-shaped fixed side columns 2 are provided on both sides of the upper end of the base 1. A water storage tank 3 is provided inside the base 1. A water baffle 4 is provided inside the water storage tank 3. 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 water flow. Normally, it is stored in the water storage tank 3, and the upper part is flush with the ground.

[0035] In this embodiment, the main body of the water-blocking plate 4 is a steel structure. The main body of the steel structure is a sealed box, which provides relatively little buoyancy after being fully raised, mainly providing sufficient water-blocking strength. The steel structure is generally made of 304 stainless steel, which can greatly improve its service life in humid underground environments.

[0036] In this embodiment, a self-locking hook 41 is provided on one side of the baffle plate 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 matches 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 provided inside the water storage tank 3. The fixed base 7 is fixed to the inner wall of the water storage tank 3 by mounting screws 72, and the front inclined surface of the baffle plate 4 is in contact with the fixed base 7.

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

[0040] In this embodiment, the bottom end of the baffle plate 4 is detachably connected to a float box 44 via a slot 5, and the float box 44 is provided with a float box fixing hole 441.

[0041] The pontoon 44 provides the main buoyancy for the water baffle 4. The pontoon 44 is mainly made of high-strength polypropylene and contains antioxidants and anti-UV components to improve its service life. It can be modularly spliced ​​and is available in four specifications according to length: 1000mm, 500mm, 200mm and 100mm. Different length combinations can be selected according to the width of the passageway on site. It is suitable for water baffle height: 0-2000mm.

[0042] In this embodiment, a drainage ditch 9 is also provided inside the base 1, and the drainage ditch 9 is connected to the water storage tank 3 through an overflow pipe 8.

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

[0044] In this embodiment, a one-way valve 81 is installed in the lower pipe body of the overflow pipe 8. The overflow pipe 8 has three main outlets: the lower drain outlet in the drainage ditch 9, the upper inlet near the ground, and the lower inlet in the water storage tank 3. The one-way valve 81 ensures that water can only flow from the water storage tank 3 to the drainage ditch 9 (when the water level has not reached the upper inlet).

[0045] In this embodiment, the top of the baffle plate 4 is provided with a baffle plate top cover 42, which is connected to the baffle plate 4 by cover plate fixing bolts 422. The baffle plate top cover 42 is provided with a sliding groove 421, which allows the L-shaped fixed side post 2 to pass through.

[0046] In this embodiment, the interior of the water baffle 4 is reinforced with multiple layers of reinforcement.

[0047] In another embodiment, the main body of the baffle plate 4 is made of high-strength polypropylene, and the upper baffle body and the float are constructed as a whole by rotational molding. The same baffle height is divided into four specifications according to the length: 1000mm, 500mm, 200mm, and 100mm, which are 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 baffle heights are 300mm, 60mm, and 1000mm, which are more suitable for baffles at lower water levels.

[0048] The working principle of this utility model is as follows:

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

[0050] When there is little rainfall, the drainage capacity of drainage ditch 9 is sufficient to meet drainage requirements, and the water level in drainage ditch 9 will not accumulate excessively. Water will not flow into the water storage tank 3 until it reaches the top of overflow pipe 8. During rain, a small amount of rainwater may enter the water storage tank 3. Due to the one-way valve 81 at the bottom, the water in the water storage tank 3 will flow into drainage ditch 9, preventing water accumulation in the water storage tank 3 and thus preventing the door panel from rising.

[0051] When rainfall exceeds the drainage capacity of the drainage system, the water level in drainage ditch 9 rises to the inlet of overflow pipe 8 and enters the water storage tank 3 through the upper inlet. Because the water level in drainage ditch 9 is higher than that in water storage tank 3, the water level in water storage tank 3 will continue to rise until the water level in drainage ditch 9 is the same and higher than the upper inlet. As the water level in water storage tank 3 rises, the buoyancy of the baffle plate 4 gradually increases. When it exceeds the weight of the baffle plate 4, the door panel begins to rise until the self-locking hook 41 of the baffle plate 4 engages with the self-locking groove 6, and the front inclined surface of the baffle plate 4 is completely in contact with the inclined surface of the fixed base 7, allowing the door panel to continue rising. At this time, the upward buoyancy of the baffle plate 4 forces the baffle plate 4 to self-lock between the two inclined surfaces, and the front and rear inclined surfaces provide a horizontal component force, causing the door panel to move towards the back of the water. At this time, the U-shaped sealing strip 43 on the baffle plate 4 is in contact with 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 and horizontal force received by the baffle plate 4. Combined with the horizontal thrust of the water on the door panel, the baffle plate will compress the sealing strip to fit the sealing surface. In other words, the higher the water level, the better the sealing effect.

[0052] The water-blocking plate 4 is supported by side columns on both sides, and its lower part is self-locked to the front and rear steel structures within the entire water-blocking span. The water-blocking plate 4 has sufficient support and will not flip over, thus achieving the purpose of blocking water.

[0053] Note: The height of the upper inlet of the overflow pipe 8 is the minimum starting height, meaning that after the external water level reaches the inlet height and overflows into the storage tank 3, the final water level in the storage tank 3 is level with the external water level. At this water level, there is sufficient buoyancy to lift the baffle plate 4 to its maximum height and enable self-locking. In other words, the buoyancy provided at the minimum starting water level is greater than the weight of the baffle plate 4 and also provides sufficient self-locking force. The external water volume is virtually unlimited relative to the storage tank 3; that is, as long as the water level exceeds the upper inlet of the overflow pipe 8, the storage tank 3 will definitely be filled.

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

[0055] The main parameters of this utility model are the water-blocking span and the water-blocking height:

[0056] The span of the water barrier 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 barriers are used.

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

[0058] Because the site conditions and circumstances vary at each installation location, the size of the equipment will be adjusted according to the actual situation.

[0059] Because this utility model requires the excavation of a foundation pit, it is more suitable for new buildings, where it can be designed into the construction site, or for existing buildings where there is excavable space on the ground. It is applicable to entrances, buildings, river sections, etc., that require protection. During river flood control, it can meet large-span flood control requirements without manual handling or excessive operations, greatly improving efficiency. Furthermore, it is located underground during normal times, so it does not affect normal work or travel.

[0060] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
