[0024] The following is a further description of the specific implementation of the utility model in conjunction with the drawings of the specification, so that the technical solution and its beneficial effects of the utility model are clearer and more explicit. The following description of the embodiments with reference to the drawings is exemplary and intended to explain the utility model, and cannot be understood as limiting the utility model.

[0025] Additional aspects and advantages of the present invention will become apparent in the following description or will be understood through practice of the present invention.

[0026] Reference Figure 1 As shown, a tap water filtration system includes a flocculation reaction tank 1, an oblique tube sedimentation tank 2 and a filtration tank 3 connected in sequence, the flocculation reaction tank 1, the oblique tube sedimentation tank 2 and the filtration tank 3 respectively have a plurality of tank body units, and a corresponding covering device 4 is respectively provided on each of the tank body units; the covering device 4 includes a first covering unit 4-1 and a second covering unit 4-2 that cooperate with each other, the first covering unit 4-1 and the second covering unit 4-2 are staggered in height to form an assembly structure that can be overlapped and unfolded, so that the covering device 4 can be opened according to different actual needs to observe and sample the water body.

[0027] Combination Figure 2 , Figure 3 As shown, the first cover unit 4-1 and the second cover unit 4-2 have similar structures, and are both composed of a cover frame 4-3, a translucent cover plate installed on the cover frame 4-3, and a roller 4-4 installed at the bottom of the cover frame 4-3. Here, the benefit of setting a translucent cover plate is that it is convenient to observe the water body and can reduce the growth of algae caused by sunlight irradiating the water body.

[0028] In this embodiment, the covering frame 4-3 is preferably an aluminum alloy frame, which is assembled by splicing a plurality of aluminum alloy profiles, and has the advantages of high strength, light weight, and not easy to rust. The top surface of the aluminum alloy frame is preferably flat to facilitate the processing and installation of the translucent cover plate. A plurality of reinforcing ribs 4-5 are also provided on the aluminum alloy frame. The reinforcing ribs 4-5 span between the side and the top of the aluminum alloy frame to support the top surface of the aluminum alloy frame, thereby meeting the application requirements of the pool unit with a larger span. In some embodiments, the covering frame 4-3 can be a stainless steel frame or a frame of other materials, not limited to this embodiment.

[0029] In this embodiment, the translucent cover is preferably a green plastic plate, such as a green PVC translucent plate, which can better reflect green light and thus better inhibit the reproduction and growth of algae. In some embodiments, the translucent cover can be a blue plastic plate or a glass plate with a green film or a blue film attached, which is not limited to this embodiment.

[0030] Recombination Figure 3 As shown, the roller 4-4 is a concave roller, and an angle steel guide rail 5 matching the concave roller is provided on each pool unit; the concave roller is buckled on the angle steel guide rail 5, runs steadily and smoothly, and the guide rail structure is simple and easy to install and use.

[0031] Combination Figure 4 As shown, in some embodiments, the top of the covering frame 4-3 is a curved surface structure, which is composed of a number of parallel curved beams 4-6, and the top portion of each curved beam 4-6 is connected to the covering frame 4-3 through a corresponding supporting beam 4-7.

[0032] The combination of the arc beams 4-6 and the support beams 4-7 realizes the top arc structure and ensures the strength of the top arc structure. Here, the advantage of setting the arc beams is that an arc-shaped translucent cover plate can be installed on the arc beams to make the top surface of the covering device 4 an arc surface, which is convenient for guiding and draining rainwater.
