Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a surface slag scooping device for water pollution prevention and control. Background Art

[0002] In public waters, water pollution prevention and control is an important part of environmental protection.

[0003] Pollutants in public waters usually include bottom sediments, large pollutants or small particles suspended in the water, and fallen leaves and white pollutants floating on the water surface. Pollutants on the water surface are visually unpleasant. More importantly, on the one hand, while polluting the water, they will block sunlight from entering the water, harming aquatic organisms. On the other hand, they are likely to decompose and release more toxic substances as they are exposed to sunlight, continuously polluting the water. Therefore, it is very important to keep the surface of public waters clean.

[0004] At present, common solutions for cleaning the surface of public waters include surface buoy interception, manual dredging nets, and manual dredging boats. Among them, the surface interception buoy is a long chain of buoys floating on the water surface that intercepts and isolates floating debris on the water surface for subsequent processing by staff. However, this solution cannot directly collect and store the debris. On the one hand, staff are still required to concentrate on dredging. On the other hand, a considerable amount of debris will still break away from the obstruction and re-enter the water area under the influence of wind and water flow, and the effect is poor. As for various forms of manual dredging nets and dredging boats, they still require manual operation by staff to search for surface debris that needs to be salvaged in the water area, which consumes a lot of manpower and material resources, but the dredging efficiency is still low. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a water surface slag scooping device for water pollution prevention and control.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A surface slag removal device for water pollution prevention and control, comprising:

[0008] A floating vessel is configured to float in a body of water, has a receiving cavity formed inside, and has an opening formed on the top, wherein the height of the opening is not higher than the surface of the water body;

[0009] A recovery bin, the lower end of which enters the accommodating cavity through the opening and is slidably connected to the floating bin; at least one water inlet is formed on the upper side wall of the recovery bin, and the bottom of the recovery bin is open and provided with a filter screen;

[0010] An air cushion is fixedly arranged around the lower outer side of the recovery bin; when the total density of the air cushion, the recovery bin and the contents of the recovery bin is not less than the density of the water body around the recovery bin, the height of the water inlet is not higher than the height of the opening.

[0011] In one possible implementation,

[0012] A protruding first outer eave is formed on the top of the recovery bin along the circumferential direction, and the height of the first outer eave is not lower than the height of the water inlet;

[0013] A protruding second outer edge is formed on the top of the floating warehouse along the circumferential direction, and the height of the second outer edge is not lower than the height of the opening;

[0014] The outer diameter of the first outer edge is not less than the diameter of the opening.

[0015] In the above possible implementations,

[0016] The outer diameter of the second outer eaves is not less than the outer diameter of the first outer eaves.

[0017] In the above possible implementations,

[0018] A first concave assembly groove is formed circumferentially on the first outer edge, and a second concave assembly groove is formed at a corresponding position on the second outer edge. The first assembly groove is adapted in shape to the second assembly groove, and the first assembly groove can be at least partially placed in the second assembly groove.

[0019] In one possible implementation,

[0020] The air cushion covers at least a portion of the lower side wall and the bottom wall of the recovery bin.

[0021] The above technical solution provided by this application has at least the following technical effects or advantages:

[0022] (1) The surface slag scavenging device for water pollution prevention and control provided by the present application uses an air cushion to make the recovery bin in the floating bin float up to expose the water inlet, so that the debris on the water surface can flow into the recovery bin through the water inlet under the influence of the water flow and be filtered out by the filter at the bottom of the recovery bin; on this basis, by adjusting the density of the air cushion, when there is a lot of debris deposited inside the recovery bin, the buoyancy of the air cushion will be insufficient to support the recovery bin and the debris deposited inside, so that the position of the water inlet remains above the water surface, and the recovery bin will sink until the water inlet is received inside the floating bin; in this way, when the recovery bin has collected enough debris, it will automatically sink to automatically seal the debris, effectively preventing the water flow from carrying the debris out of the recovery bin again and affecting the recovery effect.

[0023] (2) The surface slag scooping device for water pollution prevention and control provided by the present application can be deployed in multiple locations in polluted waters. The surging water flow drives the flow of surface debris and the sinking of the device, and can automatically suck the debris flowing around the device into the recovery bin through the water inlet, so as to realize automatic collection and storage of surface debris, and automatically hide the water inlet after recovering enough debris, so as to prevent the debris from escaping again and causing further pollution. The staff only needs to regularly clean the devices whose water inlets have sunk into the floating bin, which greatly saves manpower and material resources and improves the pollution removal efficiency.

[0028] The specific implementation of the embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0029] like Figure 1 As shown, this embodiment provides a surface slag removal device for water pollution prevention and control, which includes:

[0030] A floating vessel 1 is configured to float in a body of water, has a receiving cavity formed inside, and has an opening formed on the top, wherein the height of the opening is not higher than the surface of the water body;

[0031] The recovery bin 2 has a lower end which enters the accommodating cavity through the opening and is slidably connected to the floating bin 1; at least one water inlet 3 is formed on the upper side wall of the recovery bin 2, and the bottom of the recovery bin 2 is open and provided with a filter screen 4;

[0032] The air cushion 5 is fixedly arranged around the lower end of the recovery bin 2; when the total density of the air cushion 5, the recovery bin 2 and the contents of the recovery bin 2 is not less than the density of the water body around the recovery bin 2, the height of the water inlet 3 is not higher than the height of the opening.

[0033] In a preferred embodiment of this embodiment,

[0034] A protruding first outer eave 6 is formed on the top of the recovery bin 2 along the circumferential direction, and the height of the first outer eave 6 is not lower than the height of the water inlet 3;

[0035] A protruding second outer eave 7 is formed on the top of the floating warehouse 1 along the circumferential direction, and the height of the second outer eave 7 is not lower than the height of the opening;

[0036] The outer diameter of the first outer edge 6 is not less than the diameter of the opening.

[0037] Specifically, the protruding first outer eaves 6 and the second outer eaves 7 can increase the contact area with water; for the second outer eaves 7, the buoyancy of the floating bin 1 in the water can be further increased. For the second outer eaves 7, after the recovery bin 2 collects more debris and then sinks into the water, the pressure of the upper water flow on the recovery bin 2 can be increased, so that the water inlet 3 of the recovery bin 2 is not easy to float again and cause the pollutants to flow out.

[0038] In the above preferred embodiment, further,

[0039] The outer diameter of the second outer eaves 7 is not less than the outer diameter of the first outer eaves 6 .

[0040] In the above preferred embodiment, further,

[0041] A first concave assembly groove 8 is formed circumferentially on the first outer eave 6, and a second concave assembly groove 9 is formed at a corresponding position on the second outer eave 7. The first assembly groove 8 is adapted in shape to the second assembly groove 9, and the first assembly groove 8 can be at least partially placed in the second assembly groove 9.

[0042] Specifically, the mutually adapted first assembly groove 8 and the second assembly groove 9 can be interlocked with each other. When the recovery bin 2 drives the first outer eaves 6 to sink into the water, the interlocking of the first assembly groove 8 and the second assembly groove 9 can prevent the recovery bin 2 from floating again to a certain extent. On the other hand, the concave first assembly groove 8 will collect liquid in a concentrated manner, thereby increasing the pressure it is subjected to, thereby further strengthening the interlocking of the first assembly groove 8 and the second assembly groove 9.

[0043] In a preferred embodiment of this embodiment,

[0044] The air cushion 5 covers at least a portion of the lower side wall and the bottom wall of the recovery bin 2 .

[0045] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can refer to each other, and each embodiment focuses on the differences from other embodiments. The above embodiments are only used to illustrate the technical solutions of this application, rather than to limit this application; although the application is described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of this application.
