Problems solved by technology

There are generally two ways to use the platform at present, one is fixed by the anchor rope, and the floating platform is connected to the fixed structure on the shore by the anchor rope to position the platform. This method has a simple structure and is very convenient to install and operate. The disadvantage is that it can only be used In waters with slow flow velocity and small wind and waves, once it is applied to a watershed with turbulent flow velocity and large wind and waves, the floating platform is extremely difficult to stabilize, and the accuracy of the operation cannot be guaranteed at all, and the anchor needs to be lifted when it needs to move, and the process is more complicated; the second is to directly Fix the platform on the bottom of the water. The structure of the floating platform in this method is stable and can ensure the accuracy of construction. However, because it involves the construction of a fixed structure, the construction is difficult, and installation and disassembly are difficult, so it is difficult to promote and use it on a large scale.
The construction of underwater slotting is generally excavated at the bottom of the water, and the construction is difficult, time-consuming and labor-intensive, and the cost is relatively high
And there is no connection between these water operations, so it is necessary to provide a method for laying a straight line of underwater anchor chains to realize the connection between underwater slotting and underwater anchoring, and can solve the above-mentioned problems of floating platform operations

Embodiment 1

[0047] For the eutrophication of the water body caused by the bloom of algae on the surface of the reservoir, because of the eutrophication of the water body, a large number of algae with blue-green algae and green algae as the dominant species grow on the surface of the water body, forming a layer of "green scum" and causing the bottom to accumulate. Harmful gases produced by the decomposition of organic matter under anaerobic conditions and biotoxins produced by some plankton can also harm fish. Because eutrophication water contains nitrates and nitrites, people and animals who drink water with these substances exceeding a certain standard for a long time will also be poisoned and cause diseases, so that water resources will be polluted and cannot be reused. Therefore, it is necessary to build a barrier line of defense on the surface of the reservoir to block the algal blooms and cyanobacteria that grow on the water surface to prevent it from polluting water resources, and th...

Embodiment 2

[0059] In implementation 1, the method of laying the straight line of the underwater anchor chain is proposed to realize the laying of the straight line of the anchor chain, as the basis for the construction of the traction walking system and the underwater slotting and underwater anchoring operations. In this embodiment, the floating platform 200 can Advance or retreat along the traction chain 101, and the traction chain 101 adopts a relatively high-weight anchor chain to sink into the bottom of the water. Cooperate with the walking mode in another state to form a traction chain 101, that is, as the walking track of the floating platform 200, when in use, the role between the traction chain 101 and the floating platform 200 can be salvaged, because the weight of the anchor chain is relatively large , it is difficult to suspend above the water surface, so a small section is salvaged to interact with the floating platform 200, while the other parts are still in a sinking state, ...

Embodiment 3

[0062] Such as Figure 7 Shown is a schematic diagram of the overall structure of the water level measuring unit in the traction walking system according to the third embodiment of the present invention. When the traction chain 101 is salvaged from the bottom of the water through the rotation of the driving member 201, it can be moved according to the traction chain 101 when it is put into the bottom of the water. The depth of the water level is measured in real time, which is convenient for the operator to grasp the data of the water depth in time, so as to take corresponding protective measures and increase the safety during operation. Therefore, in this embodiment, the difference from the above-mentioned embodiments is that the traction walking system also includes a water level measurement unit 300, which is arranged on both sides of the traction chain 101, floats on the water surface S and the bottom end is in contact with the water level measurement unit 300. The drag ch...

The system comprises a traction assembly, the traction assembly comprises a traction chain and afixing assembly, the fixing assembly is arranged on both sides of the water, one end of the traction chain is connected with the fixing assembly, the other end of the traction chain is connected withan anchor gear on an anchored boat, and the traction chain is in a straightening state. The system has the advantages that by the cooperation of the arranged traction assembly and a floating platform,simple and convenient walking on the water surface of the floating platform can be achieved, the manufacturing cost is reduced, the installation processes of the traction assembly and the floating platform are simple, and the construction difficulty is greatly reduced, so that the operation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of water pollution prevention and control in hydraulic engineering, in particular to a traction walking system and a linear laying method of underwater anchor chains. Background technique [0002] In recent years, many water bodies have experienced eutrophication, which means that under the influence of human activities, a large amount of nutrients such as nitrogen and phosphorus required by organisms enter lakes, rivers, lakes, bays and other slow-flowing water bodies, causing algae and other plankton Rapid reproduction, decreased dissolved oxygen in water, deterioration of water quality, and massive death of fish and other organisms, among which planktonic algae multiply and form water blooms (a natural ecological phenomenon of algal bloom in freshwater), eutrophication will Affecting the water quality of the water body will reduce the transparency of the water, making it difficult for sunlight to penetrat...
