Detailed Description

The applicant finds that the water-facing part of the existing flood control screen is mostly a plane in actual engineering, and the reinforced rib is formed on the water-facing part through the bending surface so as to enhance the water-blocking capability of the water-facing part. Because the flood control screen is made of high polymer materials, compared with the more traditional steel flood control device, the water-blocking efficiency is relatively weaker. There is therefore a need for innovations and designs for flood screens.

As shown in fig. 1, in this embodiment, the water-facing portion is curved at a predetermined angle from both sides toward the middle to form an arched body having a substantially cylindrical arc surface. In other words, the side of the body facing the water-facing surface is arched/curved, forming an arc-shaped or arched surface. The water retaining capacity is improved through the arc-shaped surface or the arched surface. As can be seen from fig. 1 and 5, the arc angle θ refers to the angle between the reference plane of the water-facing surface and the tangent to the edge of the water-facing surface. In other words, the arc length and the arc angle of the arch surface are designed, so that the water-facing part can resist larger acting force. Under the same engineering standard, the thickness of the arched surface can be reduced, thereby reducing the weight and facilitating the transportation. Or the water resistance of the water-facing part is related to the material, the thickness, the height and the width, and is also related to the arc angle, so that the arc surface is formed, and the water resistance effect is further enhanced.

The applicant has conducted intensive studies, and has performed numerical calculations and simulations. As shown in particular in fig. 6.

Theoretical calculations and simulations show that in order to obtain a good angle of 60-80 degrees, the camber has a large amplitude, which affects manufacturing, transportation and use, and also increases the volume and weight of the flood screen. The applicant has therefore made a second optimization, namely the provision of arc-angle weakenings on both sides of the arched body. The angle is reduced to below 45 degrees, preferably to 15-30 degrees. In a specific project, the arc angle weakening part 3b can adopt a reinforcing part with a Z-shaped section, namely, the water bearing part extends a preset length towards the back water surface side reversely to form a force bearing part. Or the two sides of the upstream face are provided with reinforcing columns or reinforcing rib structures for dispersing acting force on the upstream face. Or a plurality of reinforced parts are arranged at intervals or continuously on the two sides of the upstream face, and the reinforced parts can be movably connected with the external stress device. Namely, the arch angle of the upstream surface is reduced by dispersing the acting force on the arch surface to the two sides or the bottom. So that the water-retaining device can obtain larger water-retaining acting force through smaller arching. The cylindrical arcuate or arc-shaped surface is collectively referred to as the arc-faced water portion 3a in this embodiment.

In this embodiment, one side of the water inlet part is provided with a first locking part 303 capable of installing a spring lock catch, and the other side of the water inlet part is provided with a second locking part 304 which is matched with the first locking part to lock the adjacent flood protection screen.

As can be seen from fig. 2, when the two flood protection screens are assembled together in sequence, the first locking part and the second locking part are matched to lock, so that the sealing performance and the flood protection acting force of the whole system are improved. In this embodiment, the two sides of the flood control screen are respectively provided with a C-shaped or U-shaped protrusion which can be matched with the flood control screen and extends along the edge of the upstream face and the edge of the water bearing part, and the protrusions on the two sides can be clamped together, so that when the adjacent flood control screens are installed together, a C-shaped or U-shaped sealing channel is formed on the connecting face, and the sealing and anti-seepage effect is better.

As shown in fig. 3, in this embodiment, an external support mode is adopted to improve the water retaining performance of the system, and a groove or a protrusion may be arranged on the back surface of the flood protection screen to cooperate with a support rod or similar support device, thereby improving the water retaining performance of the system.

A structure of the locking portion is described with reference to fig. 4. Specifically, the cover mainly includes a housing groove 501, a spring 502, a locking cover 503, and a cover plate 504. Form an accepting groove on the flood control screen, the bottom of accepting groove can set up spring guide or spring mounting, the one end of spring and the bottom of accepting groove, spring guide or spring mounting butt, the inner wall butt of the other end and lock lid, the apron cup joints the periphery of lock lid and is fixed with the flood control screen to form the hasp subassembly. The other side of the flood control screen can be provided with structures such as buckling holes. When adjacent flood control screen equipment, the lock lid is pressed down earlier, then resets and bounces to the locking is in the lock hole, and then forms locking structure.

In a further embodiment, at least one reinforced rib is arranged on the arched body, one end of the reinforced rib extends for a preset distance along the height direction of the arched body, and the other end of the reinforced rib extends to the water bearing part; the extending distance of the reinforced rib on the water bearing part is not more than one half of the total length of the water bearing part.

In this embodiment, the outer end of water-bearing part and clamp plate have the lock hole, lock fin formula prevention of seepage spare between clamp plate and water-bearing part through the buckle, improve fin prevention of seepage spare's sealed effect. Meanwhile, the production, installation, transportation and use are convenient.

When in use, the fin-shaped curved emergency flood control screen is assembled together. Under the operating condition, when two or more than fin formula curved surface emergency flood control screens are in the same place, along the direction that the flood control screen extends, form a plurality of arch manger plate faces. Fig. 6 shows a combination of 3 flood screens.

In a word, this technical equipment in this application has light and handy convenient, the equipment is nimble, strong adaptability, the durability is good, repeatedly usable etc. is showing the advantage, the city waterlogging manger plate scene that is applicable to under the various topography that can be better.

It should be noted that the various features described in the above embodiments may be combined in any suitable manner without departing from the scope of the invention. In order to avoid unnecessary repetition, the present invention does not separately describe various possible combinations.
