Description

Technical Field

[0001] The present invention relates to the technical field of river improvement, and more specifically, to a device for improving the icing condition of mechanical equipment in a water conveyance channel. Background Art

[0002] When water conservancy equipment operates in alpine regions or under extremely cold weather conditions, surface icing may occur. As the thickness of the ice adhering to the equipment surface increases, the impact on the working efficiency and safety of the equipment also increases. In engineering practice, measures should be taken to eliminate the adverse effects caused by icing as much as possible. Currently, the commonly used methods for preventing icing can be roughly divided into two categories: one is the active method, mainly heating and mechanical ice disturbance; the other is the passive method, such as adding a hydrophobic coating.

[0003] Using the active method to prevent icing usually requires a large amount of energy consumption. For example, heating is to use heating equipment to raise the surface temperature of water conservancy equipment above the freezing point temperature to prevent icing; mechanical ice disturbance is to use machinery or water flow impact to reduce the icing phenomenon and block the trend of continuous expansion of the adhering ice.

[0004] The use of passive methods to prevent icing has also been explored and studied by many scholars at home and abroad. Spraying superhydrophobic materials on the surface of water conservancy equipment to form a hydrophobic layer to delay or prevent icing on the metal surface; this type of method has the advantage of simple construction, but most of these methods are currently still in the laboratory exploration stage and play a limited role in solving the existing icing problems.

[0020] Compared with the prior art, the beneficial effects of the present invention:

[0021] 1. In the device for improving the icing condition of mechanical equipment in the water conveyance channel, the heat exchange component is set to conduct heat exchange with the water in the channel, increasing the heat of the water in the channel and preventing the surface of the water conveyance equipment in the water from icing.

[0042] In addition, in the description of the present invention, the meaning of "a plurality of" is two or more unless otherwise specifically defined.

[0043] Embodiment 1

[0044] Please refer to Figure 1As shown in the figure, the purpose of this embodiment is to provide a device for improving the icing condition of mechanical equipment in a water conveyance channel, which includes a heat receiving component 100, an isolation component 200, and a heat exchange component 300. The isolation component 200 is arranged at the bottom of the heat receiving component 100 and is used to isolate the heat receiving component 100 from the water surface. The heat exchange component 300 is arranged at the bottom of the heat receiving component 100 and penetrates through the isolation component 200. Its main purpose is to exchange energy between the heat (heat flow) generated in the heat receiving component 100 and the water (cold flow) in the channel, so as to increase the temperature of the water in the channel and prevent the surface of the water conveyance equipment from icing. Among them:

[0045] Please refer to Figure 2 As shown in the figure, the heat receiving component 100 includes a hot water storage cover 110 and a solar heat receiving tube 120. The solar heat receiving tube 120 is arranged outside the hot water storage cover 110. Through the arrangement and combination of multiple solar heat receiving tubes 120, a solar energy absorption area is formed outside the hot water storage cover 110. Its main purpose is to absorb the heat of solar energy and transfer the heat to the water stored in the hot water storage cover 110. In addition, in this embodiment, the heat exchange component 300 is an integrated pipe. The heat exchange component 300 passes through the isolation component 200 and is connected to the hot water storage cover 110. And the length of the integrated pipe is set according to the water depth in the channel. Its main purpose is to receive the water with heat in the hot water storage cover 110, and then transfer the heat to the water in the channel to form a cold and heat exchange and increase the temperature of the water in the river.

[0046] It is worth noting that the isolation component 200 includes an isolation board 210. The isolation board 210 is fixedly connected to the hot water storage cover 110. Considering that isolation in water requires the isolation board 210 to float on the water surface, a groove is opened at the bottom of the isolation board 210, and a foam board 220 is embedded in the groove. The above-mentioned integrated pipe specifically passes through the foam board 220 and the top wall of the isolation board 210 and is connected to the hot water storage cover 110. In addition, since the height of the river water surface cannot be controlled, the integrated pipe cannot be fixed to the river bottom. In this way, the isolation board 210 floating on the water surface will rise and fall with the water surface, so that the hot water storage cover 110 will not come into contact with the water due to the rise of the water surface. Moreover, the foam board 220 can also play a heat preservation role to avoid the loss of heat in the hot water storage cover 110. Preventing the hot water storage cover 110 from contacting the water also achieves this purpose. Therefore, the foam board 220 can not only increase the buoyancy to make the hot water storage cover 110 float, but also isolate and keep warm, killing two birds with one stone.

[0047] Embodiment 2

[0048] Considering that the sun is moving, if the solar energy absorption area is formed only on one side, the solar energy absorption rate will be reduced. Moreover, the time for the horizontally arranged solar energy absorption area to absorb solar energy will be limited because the sun will only form vertical irradiation at noon. Therefore, this embodiment discloses a setting method for the hot water storage cover 110 and the solar heat receiving tube 120. Please refer to Figure 2 As shown, the hot water storage cover 110 is a frustum structure with a square bottom surface, thus forming four inclined surfaces. 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 to absorb as much solar energy as possible and improve the utilization rate of solar energy.

[0049] Embodiment 3

[0050] Considering that if the integral pipeline cannot be fixed to the river bottom, the entire device will float randomly on the water surface. However, if it is fixed, the problem of isolation from the water surface cannot be solved. Therefore, please refer to Figure 3 and Figure 4 As shown, in this embodiment, the heat exchange component 300 includes a heat exchange tube body 310 and a heat transfer tube 320. Four groups of heat transfer tubes 320 are provided, corresponding to the four inclined surfaces of the hot water storage cover 110 respectively. A plurality of heat transfer tubes 320 are arranged along the bottom edge direction of the inclined surface in each group. The heat transfer tubes 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. Moreover, the inside of the heat transfer tubes 320 is a hollow structure. In order to allow the water with heat to flow into the heat transfer tubes 320, please refer to Figure 5 As shown, a connection port 111 is opened at the connection between the hot water storage cover 110 and the heat transfer tubes 320. The heat transfer tubes 320 communicate with the hot water storage cover 110 through the connection port 111, so that the water with heat will flow into the heat transfer tubes 320. In addition:

[0051] The heat exchange tube body 310 includes a circulation tube 311 and a negative pressure tube 312. The circulation tube 311 and the negative pressure tube 312 are connected to form an annular structure, where:

[0052] The circulation tube 311 penetrates through the isolation plate 210, the foam board 220 and the heat transfer tubes 320, and is slidably connected to the penetrated part. Therefore, in order to ensure the smoothness of sliding, the sliding part of the circulation tube 311 is a straight structure;

[0053] A negative pressure device, such as a negative pressure pump, is arranged in the negative pressure tube 312, so that water can circulate in the circulation tube 311 and the negative pressure tube 312.

[0054] Working principle:

[0055] First, the water in the circulation pipe 311 and the negative pressure pipe 312 is circulated under the action of the negative pressure pump. At the same time, since the water with heat in the hot water storage cover 110 has entered the heat transfer pipe 320, when the water circulating in the circulation pipe 311 and the negative pressure pipe 312 passes through the heat transfer pipe 320, it will absorb the heat of the water in the heat transfer pipe 320. At this time, the hot water will be recycled to the bottom of the river, conducting the heat to the river water. In this way, the efficiency of heat conduction is improved by the way of cyclic heating, solving the problem of slow cold and heat conversion efficiency of the integrated pipeline.

[0056] Meanwhile, please refer to Figure 6 As shown in the figure, where a is the rising direction of the water surface and b is the rising direction of the partition plate 210. Since both the partition plate 210 and the foam plate 220 are slidably connected to the circulation pipe 311, when the water surface rises, the partition plate 210 will drive the heat transfer pipe 320 to rise synchronously. Although the heat transfer pipe 320 rises, it can still heat the water circulating in the circulation pipe 311 to ensure the normal operation of the circulation pipe 311. At the same time, the integrated structure formed by the circulation pipe 311 and the negative pressure pipe 312 is fixed to the bottom of the river, thereby improving the stability of the entire device in the river channel.

[0057] Embodiment 4

[0058] In order to improve the heating speed of the water in the hot water storage cover 110, generally there are two methods. One is to improve the heating capacity, but the solar energy is limited and cannot continuously heat. The other is to reduce the water to be heated. For this reason, please refer to Figure 7 As shown in the figure, an inner seat 112 is arranged in the hot water storage cover 110, thereby reducing the water capacity in the hot water storage cover 110 and improving the heating speed.

[0059] In addition, considering that sometimes the sunlight is not very strong, especially in rainy and cloudy weather, the water cannot be heated normally. Therefore, an electric heating plate is arranged in the inner seat 112 to generate heat through electric energy to complete the heating of the water in the hot water storage cover 110, and also prevent part of the water in the hot water storage cover 110 from freezing.

[0060] In addition, a temperature sensor is also arranged in the hot water storage cover 110 to measure the water temperature in the hot water storage cover 110 and control the power-on of the electric heating plate in real time. Generally, when the temperature is below zero degrees, the electric heating plate will be powered on to ensure that the water in the hot water storage cover 110 does not freeze.

[0061] Embodiment 5

[0062] Considering that sometimes the water volume in the river channel is large, it is difficult to complete the heating of the river water only through one device. For this reason, the following several combination methods are disclosed in this embodiment:

[0063] First, when the heat exchange component 300 is an integrated pipeline, please refer to Figure 8As shown, two adapter plates 211 are symmetrically arranged on the outer walls of two adjacent sides of the side wall of the partition plate 210. Two connecting plates 212 are symmetrically arranged on the outer walls on both sides of the adapter plate 211. When combining, please refer to Figure 9 As shown, the adapter plate 211 of one partition plate 210 is hinged to the connecting plate 212 of another partition plate 210. The main purpose of the hinge is to overcome the stress generated by the water flow fluctuation. In this way, the heating capacity of the device is improved by combining the devices, and it is specifically set according to the conditions of different river channels.

[0064] Second, since the integrated structure formed by the circulation pipe 311 and the negative pressure pipe 312 is fixed to the river bottom, no other connecting parts need to be set, and only the arrangement positions need to be set. Therefore, there are the following arrangement methods:

[0065] Please refer to Figure 10 As shown, the integrated structure formed by the circulation pipe 311 and the negative pressure pipe 312 of one device is arranged in an interleaved manner with the integrated structure formed by the circulation pipe 311 and the negative pressure pipe 312 of another device. In this way, the interleaved part forms a high-temperature area, that is, the part shown by the dotted square in the figure. Four devices will form four high-temperature areas, and low-temperature areas will be formed between the four high-temperature areas, that is, the part shown by the dotted circular frame in the figure. In this way, the coverage area of the combined device will be reduced, but the high-temperature area will quickly exchange heat with the surrounding low-temperature areas, so the speed of increasing the water temperature of the river channel is greatly improved.

[0066] Please refer to Figure 11 As shown, two devices are arranged opposite to each other, so that a hollow part is formed between the integrated structures formed by the circulation pipe 311 and the negative pressure pipe 312 of the two devices. At this time, add two more devices, and make the integrated structure formed by the circulation pipe 311 and the negative pressure pipe 312 of the added devices fill the hollow part. In this way, the coverage area of the combined device is expanded, ensuring that the water in the river channel can be evenly heated.

[0067] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and do not limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
