[0002] Sedimentation tank is a kind of structure that uses sedimentation to remove suspended matter in water and is widely used in wastewater treatment. In sedimentation tanks, an outlet weir is often used, and water flows out from the serrations on the upper end of the outlet weir. However, in the existing design, if a worker accidentally falls into the sedimentation tank, the serrations on the upper end of the outlet weir will cause harm to the human body. In response to the above problem, a solution is proposed below. Utility Model Content

[0003] The utility model aims to provide a safety protection device for a weir plate of a sedimentation tank outlet, which has the advantages of not causing harm to the human body and not affecting the normal water outlet.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] A safety protection device for a water outlet weir plate of a sedimentation tank comprises a water outlet weir plate and a protective jacket, wherein the protective jacket is located on the upper end surface of the water outlet weir plate and is fixedly connected to the water outlet weir plate. The upper end surface of the water outlet weir plate is provided with saw teeth, and the lower end surface of the protective jacket is provided with an embedding groove, the upper end of the saw teeth is inserted into the embedding groove and is fixedly connected to the inner side of the embedding groove, the depth of the embedding groove is less than the height of the saw teeth, and the upper end surface of the protective jacket is flat.

[0006] Preferably, a plurality of stabilizing rods are fixedly provided on the saw teeth, a plurality of stabilizing grooves are provided on the lower end surface of the protective jacket, the plurality of stabilizing grooves are arranged perpendicular to the embedding grooves, and the stabilizing rods are clamped in the stabilizing grooves.

[0007] Preferably, the protective jacket is in an arc shape as a whole, the side walls at both ends of the protective jacket are vertical surfaces, and arc-shaped chamfers are provided at the connection between the upper end surface of the protective jacket and the side walls on both sides.

[0008] The utility model has the beneficial effect that when a worker accidentally falls into water, the protective jacket can prevent the saw teeth on the upper end of the water outlet weir plate from causing harm to the worker, the protective jacket is round and has no sharp parts, and the worker can grab it to complete self-rescue.

[0012] The following is only a preferred embodiment of the present invention, and the protection scope is not limited to this embodiment. All technical solutions under the concept of the present invention should belong to the protection scope of the present invention. The same parts are represented by the same figure marks. It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "bottom" and "top", "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0013] like Figure 1 and Figure 2 As shown, a safety protection device for a water outlet weir plate of a sedimentation tank comprises a water outlet weir plate 1 and a protective jacket 2. The upper end surface of the water outlet weir plate 1 is provided with saw teeth 3, and the water in the sedimentation tank can flow out from the gaps between the saw teeth 3. The protective jacket 2 is fixed to the upper end surface of the water outlet weir plate 1, and the lower end surface of the protective jacket 2 is provided with an embedding groove 4, the depth of which is less than the height of the saw teeth 3, the tip of the saw teeth 3 is inserted into the embedding groove 4, and the tip of the saw teeth 3 is fixedly connected to the protective jacket 2 by welding. Only the tip of the saw teeth 3 enters the protective jacket 2, and most of the rest of the position is located below the protective jacket 2, and the water in the sedimentation tank can pass through the saw teeth 3 located below the protective jacket 2 normally.

[0014] The upper end surface of the protective jacket 2 is flat, and the flat design prevents the protective jacket 2 from causing harm to the workers. In order to better protect the workers, a cushion layer can be provided on the outer surface of the protective jacket 2, and the cushion layer is made of a soft and elastic material, such as silica gel, etc. When selecting the material of the cushion layer, it is necessary to consider that the cushion layer will not react with the sewage in the sedimentation tank.

[0015] The protective jacket 2 is in an arc shape as a whole, and the side walls at both ends of the protective jacket 2 are vertical surfaces. The joints between the side surfaces at both ends and the upper end surfaces are chamfered in an arc shape, so that the protective jacket 2 will not scratch the human body.

[0016] In order to increase the stability between the protective jacket 2 and the water outlet weir plate 1, a plurality of stabilizing grooves 6 are provided on the lower end surface of the protective jacket 2, and a plurality of stabilizing rods 5 are fixed on the saw teeth 3. The plurality of stabilizing rods 5 are arranged perpendicular to the saw teeth 3, and the plurality of stabilizing grooves 6 are arranged perpendicular to the embedded grooves 4. When fixed, the plurality of stabilizing rods 5 will be clamped in the plurality of stabilizing grooves 6 and fixed by welding or the like. The plurality of stabilizing rods 5 not only increase the thickness of the water outlet weir plate 1 in disguised form, so that the protective jacket 2 and the water outlet weir plate 1 will not shake, but also prevent the protective jacket 2 from sliding along the length direction of the water outlet weir plate 1, thereby enhancing the stability between the protective jacket 2 and the water outlet weir plate 1.

[0017] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
