Description

Blue algae surrounding and blocking cap type opening door structure

Technical Field

The utility model relates to a water pollution treatment device, concretely relates to blue alga encloses fender cap formula mouth door structure.

Background

In recent years, due to the rapid increase of urban population, the industrialized urbanization process is accelerated, the discharge amount of nitrogen and phosphorus nutrients to water is greatly increased, and the blue algae is flooded. In 2007, the famous 'blue-green algae accident' is outbreaked in the Taihu lake, the inexhaustible blue-green algae floats on the lake surface, fishes in water die in succession, and people are afraid of drinking the water because the water quality is polluted and smells, and even the purified water in the supermarket is bought in the air. The problem of blue algae is more and more serious, and the blue algae is continuously appeared and spread in various areas, so that the water body environment is worsened, and the life of human beings and the development of society are influenced. Therefore, the method is especially important for preventing the blue algae from diffusing to the bank side when the blue algae in the Taihu lake explodes in a large amount and further enhancing the emergency prevention and control of the blue algae.

The blue algae growing violently can be treated by adopting a physical chemical and biological method. The effect and time are also good and bad due to different processing modes.

Biological algae removal means that most of water bloom algae are eaten by plankton and fish in water, and blue algae is directly captured and removed by utilizing the food chain relation of an aquatic ecosystem; the aquatic plants are planted to rob the nutrients needed by the blue algae and inhibit the growth of the blue algae. The biological algae removal and inhibition effect is obvious, and the influence on the water environment is small. However, the algae removal of the organisms needs to control the culture density and grasp the balance between the growth rate of different algae and aquatic organisms so as to have better control effect on the algae.

The chemical algae removal is to put algaecide into the water body to inhibit the growth and reproduction of algae, thereby achieving the aim of algae removal. The chemical drying time effect is fast, the process is simple, and the algae can be killed quickly. However, chemical algae removal violates national sustainable development strategy and seriously affects the water body ecosystem.

The physical algae-removing technology is used for treating explosive and large-scale blue algae crisis, such as drainage diversion, dredging of sediment, lake water coagulation and precipitation treatment, dilution and overflow, exposure and drying of sediment, deep drainage, aeration circulation, water depth increase, lake bottom coverage and the like. However, practice has shown that physical algae removal does not provide substantial control over algae production.

Along with the development of society, the problem of blue algae is solved by comprehensively using physical chemistry and biological methods, so that better environmental benefits and social benefits can be obtained, and the comprehensive treatment of algae is particularly important.

Detailed Description

Fig. 1 is a schematic view of the present invention. As shown in fig. 1, the cyanobacteria containment hat-type port structure comprises a partition 2 surrounding a bank. The enclosure 2 encloses the blue-green algae within a predetermined small range near the bank to prevent the blue-green algae from being enlarged. The enclosure 2 is provided with an enclosure opening. A hat type opening door 1 is arranged outside the enclosure 2. The bonnet door 1 is in front of the enclosure opening. The two sides of the enclosure opening are provided with wing edges protruding outside the range enclosed by the enclosure 2. The hatch 1 comprises a surrounding structure and edge structures at both side edges of the surrounding structure. The surrounding structure and the edge structure are both arc-shaped. The surrounding structure is curved towards the enclosure 2. The edge structure is curved away from the enclosure 2. The surrounding structure and the edge structure together form a hat-like shape, called a hat-style hatch 1.

The surrounding structure surrounds the enclosure opening, i.e. the length of the chord of the arc-shaped surrounding structure is greater than the opening distance of the enclosure opening.

When the passage of a ship is required, the cap-type hatch 1 does not close the enclosure opening, and a water flow channel is formed between the edge structure and the wing edge for the passage of the ship 3. When the sealed fishing is needed, the edge structure and the wing edge are connected together through an iron chain, and the cap type opening door 1 seals the enclosure opening.

The pitch arc design of wing limit and marginal structure can guarantee that the ship is smooth and easy through enclosing rivers when separating the opening, makes things convenient for ship 3 to advance out, when marginal structure and wing limit interconnect are together, can effectively seal enclosing the opening, prevents that the blue alga from spilling over.

Specifically, the enclosure 2 and the cap type opening door 1 are formed by connecting a plurality of enclosure structures. Fig. 2 is a schematic view of a containment structure. As shown in fig. 2, the containment structure comprises a floating structure 4 and a counterweight structure 5 mounted below the floating structure 4.

The floating body structure 4 comprises a rubber body 6. The rubber body 6 is provided with a plurality of through holes. In the present embodiment, as shown in fig. 2, a row of through holes is formed in the rubber body 6, and the adjacent through holes have the same pitch. The through hole is filled with a foam material 7 with a dense cylinder cutting angle. The through holes are not communicated with each other and are filled in sections. Cover plates 8 are fixed on two sides of the rubber body 6.

FIG. 3 is a schematic view of a cover plate. As shown in fig. 3, joint plates 9 are installed at both ends of the covering plate 8, and through holes are formed on the joint plates 9, so that a plurality of floating body structures can be connected together, and the connected floating body structures can be conveniently detached. The bolt connection can be used, and the binding of iron chains and the like can also be directly used.

The lower end of the cover plate 8 is provided with a fixing structure 10 for fixing the counterweight structure 5.

The counterweight structure 5 comprises a plurality of metal screens 11. The adjacent metal net curtains 11 are connected through a reinforcing band 12. The metal mesh curtain 11 is fixed under the floating body structure 4 by a clamping plate 13. Specifically, the fixing structure 10 may be a metal sheet with a through hole, one end of the clamping plate 13 is mounted on the fixing structure 10 by means of a bolt or the like, and the other end of the clamping plate 13 is a conventional clamping structure for clamping the metal mesh 11. Wherein the reinforcing band 12 is a strip-shaped tensile composite material made of polymer and used for connecting and reinforcing a plurality of metal net connections 11.

A handle 14 is arranged above the covering plate 8, so that the carrying is convenient.

The chain 15 is hung at the lower end of the metal net curtain 11. Increase the counter weight for enclose fender structure more stable.

In some embodiments, a positioning pile can be further fixed at the bottom of the lake, the metal net curtain 11 is tied on the positioning pile through an iron chain and the like, and the enclosure structure is accurately fixed and cannot be deviated.

Of course, because cap type mouthful door 1 seals and encloses the opening or opens and encloses and separate the open-ended as required, then can set up two sets of different spuds for two kinds of positions of cap type mouthful door 1, conveniently bind. Or may be adjusted according to the actual use condition, which is not described herein again.

The above description is for the purpose of explanation and not limitation of the invention, which is defined in the claims, and any modifications may be made without departing from the basic structure of the invention.
