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 method of underwater slotting is generally to excavate at the bottom of the water, which is time-consuming, labor-intensive, and relatively costly, and these problems will increase the difficulty of underwater anchoring construction

Embodiment 1

[0050] 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

[0060] The difference between this embodiment and Embodiment 1 is that the S1 step also includes the following steps:

[0061] SS1: Set up fixed piers 102a and fixed rings 102b on both banks of the reservoir;

[0062] SS2: One end of the traction chain 101 is connected to the fixed ring 102b, and the other end is connected to the anchor ship, and the anchor ship is turned on to straighten the traction chain 101 and lead to the opposite bank;

[0063] SS3: match the driving part 201 with the chain link groove of the traction chain 101 correspondingly, and drive the rotation of the driving part 201 to realize the forward or backward movement of the floating platform 200 along the traction chain 101 .

[0064] In order for the floating platform 200 to move forward or backward along the traction chain 101, that is, the driving part 201 drives the floating platform 200 to walk on the traction chain 101 through interaction with the traction chain 101, wherein the driving part 201 al...

Embodiment 3

[0068] Such as Figure 7Shown is a schematic diagram of the overall structure of the water level measuring unit in the walking system of 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 movement of the traction chain 101 when it is put into the bottom of the water. The depth measures the water level 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 chain 101 su...

Abstract

The invention discloses a travelling system and a sinking-to-bottom anchoring method for an enclosure. The sinking-to-bottom anchoring method comprises the following steps: S1, constructing the travelling system; S2, placing a grooving assembly on a waterborne working platform, and connecting the grooving assembly with the waterborne working platform; S3, sinking the grooving assembly to water bottom; S4, driving the waterborne working platform to move on water surface, and then dragging the grooving assembly back and forth on the sediment surface of the water bottom by the waterborne workingplatform; and S5, connecting an anchoring assembly with the waterborne working platform on the basis of the travelling system, and gradually sinking the anchoring assembly into the groove formed in the step S4 along with the travelling of the travelling system, thereby completing sinking-to-bottom anchoring. The travelling system and the sinking-to-bottom anchoring method have the following beneficial effects: through the cooperation action of the arranged traction assembly and floating platform, the simple and rapid travelling of the floating platform on the water surface can be realized; moreover, the manufacturing cost is lowered; and the traction assembly and the floating platform are simple in installation process, so that the construction difficulty is greatly lowered, and then the working efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of bottom sinking anchoring in hydraulic engineering, in particular to an enclosed bottom sinking anchoring method. 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 penetrate the water layer, thereby affecting the photosynth...
