Technical Field

[0001] The utility model relates to the technical field of flood drainage ditch protection, in particular to a flood drainage ditch safety protection structure. Background Art

[0002] A flood drainage ditch is an engineering facility used to intercept and remove mountain torrents in an organized and timely manner. Its design tasks are to dig ditches to divert floodwater, regulate ditches, and build structures to divert floodwater out of the protected area and discharge it into nearby water bodies. The flood drainage ditch can effectively reduce the impact of floods on surrounding areas, protect people's lives and property, and at the same time discharge groundwater and surface water, reduce flooding and waterlogging disasters, and ensure normal production and life in cities and rural areas. Protective railings are generally set on both sides of the flood drainage ditch to prevent people and animals from mistakenly entering the flood drainage ditch and causing safety accidents;

[0003] In low-light conditions at night, the visual significance of guardrails decreases, resulting in weakened perception and recognition abilities of animals. This may in turn cause animals to rush directly toward the guardrails, increasing the risk of accidental injury.

[0004] In order to solve the above problems, a flood drainage ditch safety protection structure is proposed in the present application. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0021] like Figure 1-3 As shown, a flood drainage ditch safety protection structure proposed by the utility model includes a protection fence 1;

[0022] In this embodiment, the outer periphery of the guardrail frame 1 is provided with a plurality of vertically spaced insertion holes, one of which is inserted with a detachably connected screw member 2, and a bellows 3 is installed at one end of the screw member 2. The screw member 2 includes a screw body 21 and two nuts 22, the screw body 21 is inserted horizontally into one of the insertion holes, the two nuts 22 are both threadedly sleeved on the screw body 21 and respectively abut against the two sides of the guardrail frame 1, and the bellows 3 is installed at one end of the screw body 21.

[0023] In this embodiment, a wind cavity is provided in the wind box 3, and a rod-type fan member 4 passing through the wind cavity is rotatably connected to the wind box 3. The rod-type fan member 4 includes a rotating rod 41, and openings communicating with the wind cavity are provided at the top and the bottom of the wind box 3. The rotating rod 41 rotates through the two openings, and the bottom end of the rotating rod 41 extends downward and is equipped with a blade 43, and an axial flow fan blade 42 located in the wind cavity is installed on the rotating rod 41.

[0024] In this embodiment, a pneumatic member 5 is installed at the top of the rod-type fan member 4. The pneumatic member 5 includes a fixed shaft 51, which is installed at the top of the rotating rod 41. A plurality of circumferentially arranged wind cups 52 are installed on the fixed shaft 51, and the outer periphery of the wind cups 52 is coated with a fluorescent layer.

[0025] In this embodiment, an air alarm 6 connected to the wind cavity is installed on the outer periphery of the bellows 3. The air alarm 6 includes an exhaust pipe 61 and an air nozzle 62. The exhaust pipe 61 is connected to the outer periphery of the bellows 3. An exhaust passage that penetrates and connects to the wind cavity is opened in the exhaust pipe 61. The air nozzle 62 is installed in the exhaust passage.

[0026] It should be noted that the screw body 21 can be inserted into the corresponding socket on the guardrail frame 1, and then fixed by the nut 22, so that the blade 43 at the bottom end of the rotating rod 41 extends into the flood discharge ditch and contacts the water flow. When the water flows through the surface of the blade 43, the rotating rod 41 and the axial flow fan blade 42 can be driven to rotate at the same time. When the axial flow fan blade 42 rotates, wind can be generated in the bellows 3 and discharged through the exhaust pipe 61.
