Water conservancy projects such as cold region reservoir dams and traffic engineering infrastructures such as cold region wading bridges are widely distributed worldwide. However, under the multi-factor actions of ice, high and cold, freezing and thawing and the like, the problem of freezing damage to structures of the wading infrastructure in cold areas is prominent, and particularly the structures in the fluctuation range of the surface water body are obviously damaged by the freezing damage, so that the healthy service of the wading infrastructure is seriously affected. At present, the surface water deicing technology of the surrounding area of the wading structure in the cold area is relatively lacking, and the conventional electric heating method, pressure jet flow method and compressed air bubbling method enable the deep water to move to the surface through external power supply heating or external compressed air bubbles, so that the deicing effect is achieved. However, the inventor researches find that the current deicing technology needs external power supply and energy consumption or compressed air supply and the like, and the technology consumes energy and is not environment-friendly; meanwhile, the deicing device also needs to be manually operated for a long time under severe alpine environments, and is time-consuming, labor-consuming and low in deicing efficiency. Therefore, the problem of freezing damage to the surface water body around the wading structures in the cold region cannot be effectively solved, and the safe operation of the wading structures is directly affected.
In view of the above, the designer provides an anti-freezing system for the wading concrete structure in the cold region, which is energy-saving and environment-friendly, can automatically carry out deicing operation, has less human interference, saves time and labor, and has high deicing efficiency.
Referring to fig. 1 and 2, in the present embodiment, an anti-freezing system of a cold area wading concrete structure includes a vacuum protection body 100, a flexible carrier 200, a connecting piece 300 and an unpowered heat exchange heat pipe 400, wherein the vacuum protection body 100 is provided with a closed chamber; the flexible carrier 200 and the unpowered heat exchange heat pipe 400 are both arranged in the closed cavity, the unpowered heat exchange heat pipe 400 is connected with the flexible carrier 200, and the connecting piece 300 is connected with the flexible carrier 200 and extends out of the closed cavity.
The working principle of the anti-freezing system of the wading concrete structure in the cold region provided by the embodiment is as follows:
the unpowered heat exchange heat pipe 400 can realize automatic transmission of heat of the deep high Wen Shuiti of the wading structure in the cold season to the surface layer low-temperature water body, does not need any manual operation, saves time and labor, and is low in cost. Meanwhile, the unpowered heat exchange heat pipe 400 utilizes the natural distribution characteristic that the water body temperature in the cold season increases from the surface layer to the deep layer, does not need any external power, and is environment-friendly. The flexible carrier 200 can realize multidirectional transmission of internal load of the anti-freezing system, so that the anti-freezing system can resist dead weight load and water flow dynamic load, and safety and stability of the anti-freezing system are ensured. The adoption of the flexible bearing structure is not only convenient for folding and transportation of the anti-freezing system, but also can enable the anti-freezing system to be flexibly suitable for the surfaces of the wading structures with various shapes. The vacuum-pumping protector 100 can protect the anti-freezing system from the soaking erosion of the water body, and improve the durability of the anti-freezing system. Meanwhile, the vacuumizing protecting body 100 can eliminate air in the cavity, ensure efficient heat transfer between the unpowered heat exchange heat pipe 400 and the water body, improve heat exchange efficiency and improve deicing effect. During assembly, the connector 300 is connected with a wading structure, so that the fixing is convenient, the combination of the whole anti-freezing system and the wading structure is firm and reliable, the anti-freezing system is not easy to fall off, and the use is safe.
In this embodiment, optionally, the vacuum-pumping protection body 100 may be made of thickened PVC plastic-coated waterproof cloth, so that the vacuum-pumping protection body 100 has a certain deformation capability, and can be tightly attached to the internal components thereof after vacuum pumping. Specifically, the anti-freezing system of the involved structure needs to be placed in a water body for a long time, and certain types of water bodies even have strong chemical corrosiveness, so that in order to improve the corrosion resistance durability of the anti-freezing system, the vacuumizing protection body 100 is used for wrapping and protecting the flexible carrier 200, the unpowered heat exchange heat pipe 400 and other components, and the vacuumizing protection body 100 is subjected to strict vacuumizing operation, so that the vacuumizing protection body 100 is in close contact with internal components, and the vacuumizing protection body 100 and the flexible carrier 200 are guaranteed to cooperatively deform.
It should be noted that, the vacuum protection device 100 may have a square structure, and after the vacuum is applied, the external contour of the vacuum protection device is a square.
In this embodiment, flexible carrier 200 optionally includes an outer frame 210 and a flexible waterproof fibrous mesh blanket 220. The outer frame 210 is a rectangular frame, the flexible waterproof fiber grid blanket 220 is a rectangular block, and the flexible waterproof fiber grid blanket 220 is arranged in an area surrounded by the outer frame 210 and is fixedly connected with the inner peripheral surface of the outer frame 210. For example, the flexible waterproof fiber mesh blanket 220 may be fixedly connected with the outer frame 210 by sewing. The outer frame 210 can play a role in enhancing the structural strength of the flexible waterproof fiber mesh blanket 220, preventing the flexible waterproof fiber mesh blanket 220 from being scattered from the edge, and prolonging the service life. It should be noted that, the connecting members 300 are fixedly connected to the outer frame 210, and the number of the connecting members 300 may be plural and uniformly distributed around the outer frame 210 at intervals. The connecting member 300 may be hooked, and the connecting member 300 may be fixedly connected to the outer frame 210 by a screw or the like. And unpowered heat exchange heat pipe 400 may be fixed to flexible waterproof fiber mesh blanket 220.
Specifically, flexible waterproof fibrous mesh blanket 220 has two opposing faces, each of which is rectangular, and flexible waterproof fibrous mesh blanket 220 has opposing first side 221 and second side 222. A plurality of positioning pieces 500 are installed on one of the plate surfaces, the positioning pieces 500 can be hoops made of stainless steel, and the positioning pieces 500 are used for clamping and fixing the unpowered heat exchange heat pipe 400. The number of the positioning members 500 is set as required, and each unpowered heat exchanging pipe 400 can be positioned together by the corresponding number of the positioning members 500. The flexible waterproof fiber mesh blanket 220 is further provided with a plurality of mesh bags 230, the number of the mesh bags 230 is consistent with that of the unpowered heat exchange heat pipes 400, and the mesh bags 230 are arranged close to the first side 221. Each mesh bag 230 can be woven by basalt fiber composite bar materials or galvanized steel strands, and the mesh bags 230 can be spliced by the corresponding unpowered heat exchange heat pipes 400. For example, in the present embodiment, two mesh bags 230 are disposed on the flexible waterproof fiber mesh blanket 220, and the two mesh bags 230 are arranged at intervals in the length direction of the first side 221.
In this embodiment, the unpowered heat exchange tube 400 includes a condensation tube section 410, a heat insulation tube section 420, and an evaporation tube section 430 connected in this order. When unpowered heat exchange tube 400 is mounted on flexible waterproof fiber mesh blanket 220, condenser tube segment 410 is adjacent to second side 222, evaporator tube segment 430 is adjacent to first side 221, and heat insulation tube segment 420 is located between evaporator tube segment 430 and condenser tube segment 410. The insulated tube sections 420 and the evaporator tube sections 430 are each straight tubes and extend perpendicular to the first side 221 or the second side 222. Further, the number of the condensation pipe sections 410 is multiple, one ends of the condensation pipe sections 410 are all communicated with the thermal insulation pipe sections 420, and the other ends are spaced, so that the distribution area of the condensation pipe sections 410 is wide, the area for exchanging heat with the water body can be increased, the deicing area is increased, and the deicing efficiency is improved. It should be understood that the number of the condensation pipe sections 410 is set as needed, and is not particularly limited in this embodiment.
When the unpowered heat pipe is assembled, the end part of the evaporation pipe section 430 is inserted into the corresponding mesh bag 230, and the evaporation pipe section 430, the heat insulation pipe section and the condensation pipe section 410 are all fixed on the flexible waterproof fiber mesh blanket 220 by utilizing the plurality of positioning pieces 500, so that the unpowered heat exchange pipe 400 is firm and reliable in position and is not easy to shift. When the anti-freezing system is placed in the water, the first side 221 is downward, the second side 222 is upward, and the water is vertically placed in the water, at this time, the evaporation pipe section 430 extends vertically, and because the evaporation pipe section 430 is tightly combined with the flexible waterproof fiber grid blanket 220, the evaporation pipe section 430 extends vertically after the anti-freezing system is matched with the wading building, and is not easy to deviate, so that heat transfer can be performed in the depth direction of the water better.
It should be noted that, since the flexible waterproof fiber grid blanket 220 has two opposite plate surfaces, the unpowered heat exchange heat pipes 400 can be assembled on each plate surface, so as to improve the heat exchange area and the deicing efficiency.
