[0002] The main water conveyance canal, especially the artificial main water conveyance canal, such as the main canal of a certain middle route project, conveys water by gravity from south to north, and has the characteristics of a wide artificial channel (80m - 120m) and a long distance (more than 1200km); due to the long distance of a certain middle route main canal, the latitude spans from 33° to 40°, and freezing occurs almost every year north of the Yellow River in the main canal.
[0003] At present, the main canal of a certain middle route conveys water under the ice cover during the ice period, and the safety measure is to use ice blocking cables; in this way, the water conveyance efficiency during the ice period is about half of that in normal times. Due to reasons such as flow velocity during actual operation, it is difficult to form an ice cover, and disasters such as ice jams and ice dams are likely to occur, and the actual water conveyance volume is seriously low; in addition, the freezing of the main canal will bring serious potential safety hazards to control facilities such as gates, and even cause permanent damage.
[0004] Therefore, it is necessary to develop a floating hollow polyhedron combined heat insulation and anti-freezing device on the water surface. Summary of the Invention

[0006] The second object of the present invention is to provide an installation method of such a floating hollow polyhedron combined heat insulation and anti-freezing device on the water surface.

[0008] Boundary constraint devices are arranged on both sides of the honeycomb air hood, there is a transverse pressing plate at the top of the honeycomb air hood, and the honeycomb air hood is composed of a plurality of hollow polyhedron strip columns in close contact with each other;
[0009] There is a protective lining plate between the boundary constraint device and the slope of the main water conveyance canal.
[0010] In the above technical solution, the hollow polyhedron strip column is a hexagonal prism, the edges are rounded, and the hollow polyhedron strip column is made of food-grade polyethylene transparent material.
[0011] In the above technical solution, the boundary constraint device is made of stainless steel material, and the transverse pressing plate is made of stainless steel material.
[0012] In the above technical solution, the inner diameter of the hollow polyhedron strip column is 0.1m - 0.5m, and the length is 10m - 20m.
[0013] In the above technical solution, the honeycomb air hood is composed of a layer of hollow polyhedron strip columns.
[0014] In the above technical solution, there are horse paths on both sides of the water conveyance main canal.
[0015] In order to achieve the above second object, the technical solution of the present invention is: an installation method of a water surface floating hollow polyhedron combined heat insulation and anti-freezing device, which is characterized by including the following steps:
[0016] Step 1: Lay protective liners on the two slopes of the water conveyance main canal channel;
[0017] Step 2: Use the slide plate structure of the protective liner to lay hollow polyhedron strip columns on the water surface until a honeycomb air hood is formed;

[0019] Compared with the prior art, the present invention has the following advantages:
[0020] 1) In the present invention, a plurality of hollow polyhedron strip columns are placed on the open water surface of the water conveyance main canal, floating in combination with each other, and using a certain self-weight and boundary constraints to form a "honeycomb" - type honeycomb air hood on the water surface of the water conveyance main canal, so as to effectively isolate the floating section of the water surface from the external atmosphere, achieving the purpose of heat insulation and anti - freezing. It can effectively prevent the water conveyance main canal from freezing during the ice period, greatly improving the water conveyance efficiency of the water conveyance main canal during the ice period; at the same time, it can prevent secondary disasters caused by the freezing and thawing of the main canal, ensuring the safety of facilities such as the water conveyance main canal and its control gates.
[0021] 2) The present invention can effectively prevent the water conveyance main canal of a certain middle - line project from freezing in winter, thus replacing the complex, passive and inefficient ice - cover water conveyance method, realizing normal ice - free water conveyance in the main canal during the ice period.

[0025] The following will describe in detail the implementation of the present invention in conjunction with the accompanying drawings. However, they do not constitute a limitation to the present invention and are only for illustration purposes. At the same time, the advantages of the present invention will become clearer and easier to understand through the description.
[0026] Referring to the accompanying drawings, it can be seen that for the floating hollow polyhedron combined heat insulation and anti-freezing device on the water surface, this device is used under the condition of ice-period water conveyance in the main water conveyance canal 1, and includes a honeycomb air hood 2 located in the main water conveyance canal 1, with the upper end above the water level line and the lower end below the water level line;
[0027] Boundary restraint devices 3 are arranged on both sides of the honeycomb air hood 2, there is a transverse pressing plate 4 on the top of the honeycomb air hood 2, and the honeycomb air hood 2 is composed of a plurality of hollow polyhedron strip columns 21 in close contact with each other;
[0028] There is a protective lining plate 11 between the boundary restraint device 3 and the slope of the main water conveyance canal 1.
[0029] The hollow polyhedron strip column 21 is a hexagonal prism with rounded edges, and the hollow polyhedron strip column 21 is made of food-grade polyethylene transparent material.
[0030] The boundary restraint device 3 is made of stainless steel material, and the transverse pressing plate 4 is made of stainless steel material.
[0031] The inner diameter of the hollow polyhedron strip column 21 is 0.1 m - 0.5 m, and the length is 10 m - 20 m.
[0032] The honeycomb air hood 2 is composed of 3 - 4 layers of hollow polyhedron strip columns 21.
[0033] There are access roads 5 on both sides of the main water conveyance canal 1.
[0034] The installation method of the floating hollow polyhedron combined heat insulation and anti-freezing device on the water surface is characterized by including the following steps:
[0035] Step 1: Lay the protective lining plates 11 on the two slopes of the main water conveyance canal 1;
[0036] Step 2: Use the slide plate structure of the protective lining plate 11 to lay the hollow polyhedron strip columns 21 on the water surface, place 3 - 4 layers until the honeycomb air hood 2 is formed;
[0037] Step 3: Install the boundary restraint device 3 on the protective liner 11. At the same time, install the transverse pressure plate 4 on the top of the honeycomb air hood 2 to form an airtight structure for the honeycomb air hood 2. The boundary restraint device 3 and the transverse pressure plate 4 are fixedly connected and anchored through the protective liner 11. The whole device floats on the water surface, forming an air isolation without affecting the water conveyance of the main canal; the installation is completed.
[0038] In actual use, the water conveyance main canal 1 is an open canal, and the channel is an artificial concrete-lined flow channel without covering on the top; there are access roads 11 for operation inspection and transportation and maintenance equipment on both sides of the water conveyance main canal 1. The access roads 11 are made of concrete or asphalt, and there are buffer protection forest belts on both sides of the access roads 11 for closed management and ensuring water quality safety.
[0039] The protective liner 11 is used for the fixation and protection of the boundary restraint device 3 on the canal slope, provides an anchoring structure and a fixed support, and is convenient for disassembly and assembly without affecting the canal slope of the main canal, and can realize the rapid paving (skid-mounted paving) of the honeycomb air hood 2.
[0040] The hollow polyhedron strip column 21 is a hexagonal prism with a regular hexagonal cross-section and a hollow thin wall. It is made of food-grade polyethylene transparent material, and its specifications can be set according to the width of the channel. Generally, the inner diameter is 10 cm - 50 cm, and the edges of the hexagonal prism are smooth rounded corners, so that multiple hexagonal prisms can be combined with each other on the water surface. Under the condition of being constrained on both sides and at the top, the surfaces of multiple hexagonal prisms are in close contact with each other, thus forming a "honeycomb"-type laminated cross-section and a "labyrinth"-type air isolation structure; due to the use of transparent material and airtight structure, the hollow polyhedron strip column 21 absorbs heat radiation during the day with sunlight, heating the air temperature inside the column, which is more conducive to heat insulation from the atmosphere at night and effectively prevents the water surface from freezing.
[0041] The boundary restraint device 3 is used to install on both sides of the hollow polyhedron strip column 21 after the hollow polyhedron strip column 21 covers and laminates on the water surface, and is used to restrain and anchor the hollow polyhedron strip column 21. While preventing the hollow polyhedron strip column 21 from slipping along the water flow, it provides boundary constraints on both sides for the laminated hollow polyhedron strip column 21, so that the hollow polyhedron strip column 21 is subject to side binding forces and keeps the surfaces of the hollow polyhedron strip column 21 in close contact with each other.
[0042] The transverse pressure plate 4 is used to form constraints and anchors on the top of the hollow polyhedron strip column 21 after the hollow polyhedron strip column 21 covers and laminates on the water surface. While preventing the hollow polyhedron strip column 21 from slipping along the water flow, it provides boundary constraints on the top for the laminated hollow polyhedron strip column 21, so that a certain binding force is conducted from the upper part of the column surface of the hollow polyhedron strip column 21, thereby making the surfaces of the hollow polyhedron strip column 21 in close contact with each other.
[0043] After the ice age ends, disassemble the device in a reversible order. Clean it outside the water conveyance main canal 1 and then pack and seal it for use in the next ice age.
[0044] The structures of each section of the honeycomb air hood 2 can be connected end to end and seamlessly joined to achieve long-distance anti-freezing and ice-free water conveyance in the main canal.
[0045] Other parts not described belong to the prior art.
