Problems solved by technology

[0004] The use of passive methods to prevent icing has also attracted the exploration and research of many scholars at home and abroad, using super-hydrophobic materials to spray on the surface of water conservancy equipment to form a hydrophobic layer to delay or prevent the phenomenon of icing on metal surfaces; this type of method has the advantage of simple construction, However, most of these methods are still in the stage of laboratory exploration, and have limited effect on solving the existing icing problems.

Embodiment 1

[0044] see figure 1 As shown, the purpose of this embodiment is to provide a device for improving the icing of mechanical equipment in water transport channels, including a heating assembly 100, an isolation assembly 200, and a heat exchange assembly 300. The isolation assembly 200 is arranged at the bottom of the heating assembly 100 for The heat receiving component 100 is isolated from the water surface, and the heat exchange component 300 is arranged at the bottom of the heating component 100 and runs through the isolation component 200. Energy exchange is carried out, thereby increasing the temperature of the water in the river channel, and the surface of the water delivery equipment freezes, among which:

[0045] see figure 2 As shown, the heating assembly 100 includes a hot water storage cover 110 and a solar heating tube 120. The solar heating tube 120 is arranged outside the hot water storage cover 110, and the arrangement and combination of a plurality of solar heat...

Embodiment 2

[0048] Considering that the sun is moving, if the solar absorption area is only formed on one surface, the absorption rate of solar energy will be reduced, and the solar absorption time of the horizontal solar absorption area will be limited, because the sun will only be formed at noon Vertical irradiation, for this reason, this embodiment discloses a kind of arrangement mode of hot water storage cover 110 and solar heat receiving tube 120, please refer to figure 2 As shown, the hot water storage cover 110 is a prism structure with a square bottom surface, thereby forming four inclined surfaces, and a plurality of solar heat receiving tubes 120 are arranged along the bottom edge on the four inclined surfaces, thereby forming four solar energy absorption areas. It is possible to absorb more solar energy and improve the utilization rate of solar energy.

Embodiment 3

[0050] Considering that if the integrated pipeline cannot be fixed to the bottom of the river, the whole device will float randomly on the water surface, but if it is fixed, the problem of isolation from the water surface cannot be solved. For this reason, please refer to image 3 and Figure 4 As shown, in this embodiment, the heat exchange assembly 300 includes a heat exchange pipe body 310 and a heat transfer pipe 320. There are four sets of heat transfer pipes 320, respectively corresponding to the four inclined surfaces of the hot water storage cover 110, and each group is arranged along the bottom of the inclined surface. A plurality of heat transfer pipes 320 are arranged in the side direction, and the heat transfer pipes 320 are fixed to the top wall of the isolation plate 210 and connected to the side wall of the hot water storage cover 110, and the inside of the heat transfer pipes 320 is a hollow structure, in order to allow the water with heat to flow into inside h...

Abstract

The invention relates to the technical field of river channel improvement, in particular to a device for improving the icing condition of water delivery river channel mechanical equipment. The device comprises a heated assembly, an isolation assembly and a heat exchange assembly, the isolation assembly is arranged at the bottom of the heated assembly and used for isolating the heated assembly from the water surface, and the heat exchange assembly is arranged at the bottom of the heated assembly and used for conducting energy exchange on heat generated in the heated assembly and water in a river channel. Water in a river channel is subjected to heat exchange through the arranged heat exchange assembly, the heat of the water in the river channel is improved, and the surface of water conveying equipment in the water is prevented from being frozen; in addition, a foam plate prevents the hot water storage cover from making contact with the water and conducts heat preservation, so that the foam plate can increase buoyancy to make the hot water storage cover float and can conduct isolation and heat preservation.

Description

technical field [0001] The invention relates to the technical field of river channel improvement, in particular to a device for improving the icing condition of mechanical equipment of a water delivery channel. Background technique [0002] When water conservancy equipment operates in alpine regions or in extremely cold weather, surface icing will occur. As the thickness of the ice attached to the surface of the equipment increases, the impact on the working efficiency and safety of the equipment will also increase. Measures should be taken in engineering practice Eliminate adverse effects due to icing as much as possible. At present, the methods commonly used to prevent icing can be roughly divided into two categories: one is active methods, mainly heating and mechanical ice disturbance; the other is passive methods, such as adding a hydrophobic coating. [0003] Aggressive methods of preventing icing are usually energy-intensive. For example, heating is to use heating eq...
