[0038] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below with reference to the embodiments and drawings. The illustrative embodiments of the present application and the description thereof are only used to explain the present application and should not be regarded as a limitation of the present application.

[0039] It should be noted that when a component is referred to as being "fixed" or "disposed" on another component, it can be directly on the other component or indirectly on the other component. When a component is referred to as being "connected to" another component, it can be directly or indirectly connected to the other component.

[0040] It should be understood that the terms "length", "width", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the present application and simplify the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0041] In addition, the terms "first", "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0042] The present application provides an automatic lifting type water blocking device, which can be referred to Figures 1-2The automatic lifting water-blocking device includes a water-blocking component 3 and a limiting component 2. The water-blocking component 3 is configured to float on the water surface. The water-blocking component 3 can be constructed as a buoyancy plate or a buoyancy block can be set on the water-blocking component 3, so that the water-blocking component 3 can float on the water surface in a natural state. The water-blocking component 3 is slidably connected to the limiting component 2, so that when the water level rises, the buoyancy force applied by the water to the water-blocking component 3 can make the water-blocking component 3 slide on the limiting component 2. The limiting component 2 is used to connect to the inner wall of the drainage channel 1 so that the water-blocking component 3 can slide back and forth in the depth direction of the drainage channel 1, that is, when the water-blocking component 3 slides on the limiting component 2, the water-blocking component 3 or part of the structure of the water-blocking component 3 can be located outside the drainage channel 1.

[0043] When installing the automatic lifting water-blocking device, the limiting component 2 is fixedly connected to the side wall of the drainage ditch 1 away from the road 4. A certain gap is maintained between the water-blocking component 3 and the bottom of the drainage ditch 1. This allows water to flow directly through the gap between the water-blocking component 3 and the bottom of the drainage ditch 1 when there is little water accumulation on the road 4. When there is little water accumulation and no need to block water, the water-blocking component 3 will not rise due to buoyancy and can be completely hidden inside the drainage ditch 1, ensuring the aesthetics of the road 4 and avoiding obstruction of pedestrian traffic. Figure 8 As shown, when road 4 is flooded and there is no need to block the water, the water level in drainage ditch 1 rises, causing the water-blocking component 3 to be positioned outside the drainage ditch 1. This small portion of the water-blocking component 3 will not cause significant obstruction to pedestrians, nor will it appear obtrusive. Furthermore, this small portion of the component can provide a certain degree of water-blocking effect, which can cope with sudden increases in water accumulation. Figure 9 As shown, when there is a lot of water accumulation on road 4 and there is a need to block the water, the water level in the drainage ditch 1 rises to its maximum. Most of the structure or the entire water-blocking component 3 is located outside the drainage ditch 1. The water-blocking component 3 provides the maximum water-blocking area. At this time, the water-blocking component 3 is equivalent to forming a high barrier on one side of road 4, thereby effectively blocking the water accumulation on road 4 and preventing the water accumulation on road 4 from directly crossing the drainage ditch 1 to reach other areas such as human living areas. When the water accumulation on road 4 decreases, the water-blocking component 3 drops as the water level in the drainage ditch 1 drops, so that most of the structure of the water-blocking component 3 is hidden inside the drainage ditch 1 or the entire water-blocking component 3 is hidden inside the drainage ditch 1.

[0044] In some alternative embodiments, see [reference]. Figures 3-4 The water-blocking component 3 includes a water-blocking plate 31 and a buoyancy member 32; the buoyancy member 32 is connected to the side of the water-blocking plate 31 and is used to contact the water surface.

[0045] In the embodiments of the present application, the water blocking assembly 3 is divided into a water blocking plate 31 and a buoyant member 32. Compared with the water blocking assembly 3 being provided as a buoyant material member as a whole, the water blocking plate 31 has more optional types of materials, for example, a material with lighter mass and better structural strength can be selected to ensure that the water blocking plate 31 has better water blocking effect, and the water blocking assembly 3 as a whole obtains the buoyancy provided by the water flow through the buoyant member 32 to float on the water surface. In actual implementation, the shape of the water blocking plate 31 is determined according to the extension direction of the drainage channel 1. For example, for a straight section of the drainage channel 1, the overall shape of the water blocking plate 31 is a rectangular plate body with a length equal to the length of the straight section of the drainage channel 1. For an arc section of the drainage channel 1, the overall shape of the water blocking plate 31 is an arc-shaped plate with a length equal to the length of the arc section of the drainage channel 1. For an S-shaped section of the drainage channel 1, a plurality of arc-shaped water blocking plates 31 can be combined to form an arc-shaped water blocking plate 31. If the length of the straight section / arc section is relatively long, a plurality of rectangular plate bodies or arc-shaped plate bodies can be provided for splicing.

[0046] In some optional embodiments, the buoyant member 32 is configured as a foam block.

[0047] In the embodiments of the present application, the foam block has the characteristics of light weight, high buoyancy and water resistance, and can effectively provide the required buoyancy of the water blocking assembly 3. When the water level in the drainage channel 1 rises, the foam block is subjected to the buoyant force of the water, which pushes the water blocking assembly 3 to slide upward along the limiting assembly 2, so that the water blocking assembly 3 is partially or entirely exposed from the drainage channel 1, thereby forming a water blocking barrier. The buoyancy characteristics of the foam block ensure that the water blocking assembly 3 can automatically rise and fall with the change of the water level, which can hide in the drainage channel 1 at low water level to maintain the beauty of the road 4 and smooth transverse traffic, and can timely rise at high water level to effectively block the overflow of the water accumulated on the road 4 over the drainage channel; the foam block material has low cost and is easy to process, which can meet the requirements of water blocking assemblies 3 of different shapes and sizes, and further improves the practicality and economy of the device.

[0048] In some optional embodiments, the number of the buoyant members 32 can be configured as multiple and arranged at intervals on the water blocking plate 31. Figure 2 Figure 3

[0049] In the embodiments of the present application, the arrangement of multiple buoyant members 32 can make the force on the water blocking assembly 3 more uniform during the lifting and lowering process, avoiding the problems of inclination or jamming caused by uneven distribution of buoyancy, thereby improving the stability and reliability of the water blocking assembly 3.

[0050] In some optional embodiments, the buoyant members 32 are arranged at equal intervals on the water blocking plate 31.

[0051] ​​In the embodiments of the present application, the buoyancy members 32 arranged at equal intervals can make the water retaining assembly 3 bear force more evenly during lifting, avoid local stress concentration or tilting caused by uneven distribution of buoyancy, and thus ensure that the water retaining assembly 3 can stably and smoothly lift with water level changes; at the same time, the buoyancy members 32 arranged at equal intervals can also effectively disperse the impact force of water flow on the water retaining assembly 3, and enhance the overall stability and durability of the water retaining assembly 3.

[0052] In some optional embodiments, referring to Figures 5-7 , the limiting assembly 2 includes a limiting plate 21, a guide sliding block 24 and a connecting rod 23; the limiting plate 21 is provided with a guide sliding groove 22, wherein the guide sliding groove 22 is divided into a first section and a second section from the direction of the groove mouth to the groove bottom, the width of the first section is smaller than the width of the second section, and the first section and the second section can be continuous, for example, the cross-sectional shape of the guide sliding groove 22 in the width direction is isosceles trapezoidal, that is, the guide sliding groove 22 is a dovetail groove, or the first section and the second section can be discontinuous, for example, the cross-sectional shape of the guide sliding groove 22 in the width direction is a convex shape, the limiting plate 21 is used to connect the inner side wall of the drainage channel 1, and expansion bolts can be used to connect the limiting plate 21 and the inner side wall of the drainage channel 1 to ensure the connection stability; the guide sliding block 24 cooperates with the second section to slide back and forth in the second section; and the connecting rod 23 is connected with the guide sliding block 24 and the water retaining assembly 3 at both ends.

[0053] In some optional embodiments, when the cross-sectional shape of the guide sliding groove 22 in the width direction is a convex shape, the guide sliding block 24 is configured as a pulley.

[0054] In the embodiments of the present application, the arrangement of the pulley can significantly reduce the friction between the guide sliding block 24 and the guide sliding groove 22, make the water retaining assembly 3 more smooth and flexible during lifting, not only reduce the resistance when the water retaining assembly 3 moves, but also reduce the wear caused by friction, thereby prolonging the service life of the limiting assembly 2; and the structural design can also improve the response speed of the device, so that the water retaining assembly 3 can quickly adjust the position with water level changes and provide effective water retaining effect in time. In actual implementation, the width of the second section is slightly larger than the diameter of the guide sliding block 24, that is, when the guide sliding block 24 cooperates with the second section, the guide sliding block 24 is in contact with one of the groove walls of the second section.

[0055] In some optional embodiments, the number of guide sliding grooves 22 is multiple and arranged in parallel and at intervals.

[0056] In the embodiments of the present application, the arrangement of multiple guide sliding grooves 22 can further ensure the movement stability of the water retaining plate 31, ensure that the movement direction of the water retaining plate 31 under the action of buoyancy is correct, and the risk of jamming during the upward or downward movement of the water retaining plate 31 is smaller compared with the arrangement of a single guide sliding groove 22.

[0057] In some alternative embodiments, the inner wall of the guide groove 22 is coated with a wear-resistant and corrosion-resistant coating, and the outer surfaces of the guide slider 24 and the connecting rod 23 are coated with a wear-resistant and corrosion-resistant coating.

[0058] In this embodiment, relative movement occurs between the guide groove 22 and the connection, and between the guide groove 22 and the guide slider 24. By applying a wear-resistant and corrosion-resistant coating, the wear between components can be reduced, and water erosion can be prevented, ensuring the service life of the device and maintaining a considerable response speed even during long-term service. The wear-resistant and corrosion-resistant coating can be, for example, a polyurethane coating, an epoxy coating, a ceramic coating, a polytetrafluoroethylene coating, or a tungsten carbide coating.

[0059] In some optional embodiments, a limiting hole 25 is provided on the limiting component 2. In actual implementation, the limiting hole 25 can be designed as a circular hole. The limiting hole 25 is provided on the limiting plate 21. After the limiting plate 21 is connected to the inner wall of the drainage ditch 1, the length direction of the limiting hole 25 is parallel to the depth direction of the drainage ditch 1, which means that the length direction of the limiting hole 25 is parallel to the sliding direction of the water-blocking component 3. The water-blocking component 3 has a limiting rod 33 that can form a shaft hole fit with the limiting hole 25. The limiting rod 33 can be designed as an L-shaped circular rod. The limiting hole 25 is an L-shaped groove adapted to the shape of the limiting rod 33. One section of the limiting rod 33 is perpendicular to the plate surface of the water-blocking plate 31, and the other section is movably inserted into the limiting hole 25. In this configuration, the limiting rod 33 slides axially within the limiting hole 25 as the water-blocking assembly 3 slides. The length of the limiting rod 33 within the limiting hole 25 is greater than the maximum stroke of the water-blocking plate 31. This means that even when the water-blocking plate 31 rises to its highest position, a portion of the limiting rod 33 remains within the limiting hole 25. This configuration ensures that the cooperation between the limiting plate 21 and the limiting rod 33 provides support to the water-blocking plate 31 during water blocking, thereby enhancing its water-blocking capacity. It also alleviates the load-bearing pressure on the cooperation structure between the guide slider 24 and the guide groove 22, ensuring the integrity of the cooperation structure and reducing the risk of jamming between the guide slider 24 and the guide groove 22.

It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model.
