Description

Technical Field

[0001] The utility model relates to the technical field of ice melting, and in particular to an anti-icing device. Background Art

[0002] Currently, many cities and businesses along the Yellow River rely on the river for their daily lives and production. When the river freezes over, a 70-100cm layer of ice forms on the river surface. Existing methods typically involve manual or mechanical extraction of water. This involves breaking the ice in a specific water area to expose the water. Then, either manually breaking the ice multiple times or installing a disturbance pump (a disturbance pump jet heat exchanger) extracts water from the bottom 3-6 meters below the surface at a constant temperature (approximately 4-6°C).

[0003] However, in previous icebreaking work, it was found that when manual icebreaking was adopted in specific water intake waters on a regular basis, not only was the icebreaking area small and labor-intensive, but it was also dangerous and inefficient. When a disturbance pump was installed to disturb heat exchange in specific waters, the effect was better when the outdoor temperature was above -15°C and the water intake water depth was greater than 4m. When the outdoor temperature was below -15°C, the efficiency of icebreaking heat exchange would drop rapidly as the outdoor temperature dropped, resulting in a gradual reduction in the icebreaking area in the specific water intake waters. When the water intake water depth was below 4m, the heat extracted from the water by the submersible pump would quickly disappear in the specific water intake waters, and the already broken ice would quickly refreeze, affecting normal water intake.

[0024] In order to solve the problems of low water intake efficiency and limited water intake conditions in the water intake method in the prior art, the present application provides an anti-icing device.

[0025] like Figure 1 and Figure 2 As shown, the anti-icing device includes a workbench 10 and an anti-icing assembly. The workbench 10 is installed in the water intake area. The anti-icing assembly includes a delivery manifold 20, a pump body 30, a spray unit 40, a first branch pipe 50, a second branch pipe 60, and a control valve. The delivery manifold 20 is installed on the workbench 10. The pump body 30 is located in the water intake area and is used to pump water into the delivery manifold 20. The first ends of the first branch pipe 50 and the second branch pipe 60 are both connected to the delivery manifold 20. The second end of the first branch pipe 50 is connected to the spray unit 40, which is located in the water intake area and sprays water into the water intake area. The second end of the second branch pipe 60 is connected to the steam supply device to deliver steam into the delivery manifold 20. The control valve is installed on the second branch pipe 60 to control the connection between the second branch pipe 60 and the delivery manifold 20 and / or the flow rate or flow rate of the steam in the second branch pipe 60.

[0026] By applying the technical solution of this embodiment, when water needs to be drawn from the water intake area, the ice surface in the water intake area is first broken to expose the water surface, and then the pump body 30 is activated to continuously pump the water in the water intake area into the delivery main pipe 20 through the pump body 30. During the water intake process, the water can enter the injection unit 40 through the first branch pipe 50 to prevent secondary freezing in the water intake area. At the same time, the second branch pipe 60 can be selected for use based on the environment in which the water intake area is located. If the ambient temperature in the water intake area is low, the control valve can be controlled to open, allowing the steam in the steam supply device to enter the delivery main pipe 20 through the second branch pipe 60. The delivery main pipe 20 then performs temperature compensation on the water intake area, so that the anti-icing device can be used in an unrestricted environment. This solves the problem of low water intake efficiency and limited water intake conditions in the existing water intake method, thereby improving water intake efficiency.

[0027] Optionally, the pump body 30 is a disturbance pump. The disturbance pump is hoisted 3 to 6 meters underwater and away from the riverbank. One end of the delivery main pipe 20 is connected to the outlet of the disturbance pump. The above-water portion of the delivery main pipe 20 is laid along the workbench 10. A first branch pipe 50 and a second branch pipe 60 are welded to the delivery main pipe 20. The first branch pipe 50 is connected to the injection unit 40 installed on the floating platform 100, forming an ice melting system to prevent secondary freezing in a specific water intake area.

[0028] In this embodiment, underwater river water with a certain temperature is extracted by a disturbance pump, and heat exchange is used to prevent the specific water intake area from freezing again, thereby completing the water intake operation in the specific water intake area in winter.

[0029] Optionally, the anti-icing device further includes a temperature detection device and a control module. The temperature detection device is used to detect the temperature of the environment in which the anti-icing device is located. The control module is electrically connected to both the temperature detection device and the control valve. When the temperature detection value of the temperature detection device is less than a preset temperature value, the control valve is controlled by the control module to be in an open state. Thus, through temperature detection and intelligent control, the anti-icing device can automatically control whether the second branch pipe 60 is put into use according to the ambient temperature, effectively avoiding unnecessary energy waste and performing temperature compensation on the water intake area to prevent ice from forming in the water intake area and affecting water intake.

[0030] In this embodiment, the temperature detection device is used in conjunction with the control module, so that the anti-icing device can automatically adjust the steam supply according to real-time temperature data, avoiding wasting energy when the temperature is still acceptable, and quickly start steam for temperature compensation when the temperature drops sharply to prevent ice from forming in the water intake area.

[0031] like Figure 2As shown, the anti-icing assembly also includes a heating belt 70. The heating belt 70 is disposed outside the delivery manifold 20; the heating belt 70 extends longitudinally and / or axially along the delivery manifold 20; alternatively, the heating belt 70 is spirally wound around the delivery manifold 20. This arrangement further enhances the anti-freezing capability of the delivery manifold 20 and expands the water intake range of the anti-icing device. Furthermore, this arrangement allows for greater flexibility in the placement of the heating belt 70 on the delivery manifold 20, accommodating diverse usage requirements and operating conditions, while also increasing operator flexibility.

[0032] In this embodiment, the heating belt 70 is spirally wound around the outside of the transport main pipe 20, thereby providing an additional heat source for the transport main pipe 20, maintaining the fluidity of the water in the pipe even at extremely low temperatures, and enhancing the anti-freezing effect.

[0033] like Figure 2 As shown, the anti-icing assembly also includes an insulating outer shell 80 and an insulating layer 90. The insulating outer shell 80 is mounted over the main delivery pipe 20, with the insulating layer 90 positioned between the main delivery pipe 20 and the insulating outer shell 80. This dual protection provided by the insulating layer 90 and the insulating outer shell 80 effectively reduces heat loss and maintains a constant temperature within the main delivery pipe 20, making it suitable for prolonged low-temperature operations, such as reservoir water extraction in winter.

[0034] In this embodiment, the combination of the insulating outer shell 80 and the insulating layer 90 provides a closed, insulated environment for the main delivery pipe 20. This maintains the water temperature within the pipe and prevents ice formation even during prolonged low-temperature operations. Furthermore, the insulating layer 90 reduces heat loss during steam heating, further improving energy efficiency and reducing operating costs.

[0035] Optionally, the insulation layer 90 is made of polyurethane or polyethylene insulation. This configuration ensures that the insulation layer 90 has excellent thermal insulation properties, preventing rapid heat loss. Furthermore, this configuration allows for greater flexibility in the selection of materials for the insulation layer 90, meeting varying requirements and operating conditions, while also enhancing operator flexibility.

[0036] In this embodiment, the heat-insulating layer 90 is made of polyurethane material.

[0037] Optionally, there is a single anti-icing assembly; alternatively, there are multiple anti-icing assemblies, spaced apart along the width of the workbench 10. This arrangement allows for greater flexibility in the number of anti-icing assemblies, meeting varying requirements and operating conditions, while also enhancing operator flexibility. Furthermore, the use of multiple anti-icing assemblies can increase the coverage area of ​​the water intake, making it suitable for large-scale water intake operations.

[0038] In this embodiment, there are two anti-icing assemblies, which are spaced apart along the width direction of the workbench 10 to improve the anti-icing performance of the anti-icing device. The two anti-icing assemblies are put into use simultaneously.

[0039] In other embodiments not shown in the drawings, the two anti-icing assemblies are put into use at different times.

[0040] It should be noted that the number of anti-icing components is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, there are three, four, five, or more anti-icing components.

[0041] Optionally, the anti-icing device also includes a battery. The battery is electrically connected to the pump body 30, the temperature detection device, the control module, and the heating belt 70. This battery configuration enables the anti-icing device to continue operating even in the event of a power outage, improving its stability and reliability. Furthermore, this configuration allows for unrestricted use of the anti-icing device, further enhancing its versatility.

[0042] like Figure 1 As shown, the anti-icing device also includes a floating platform 100 and an anchor assembly. The first branch pipe 50 and the ejector unit 40 are both mounted on the floating platform 100. The anchor assembly includes a towing rope and an anchor body. One end of the towing rope is connected to the floating platform 100, and the other end is connected to the anchor body. The floating platform 100 is made of polyethylene. This arrangement allows the ejector unit 40 to move with fluctuations in the water surface, preventing equipment damage caused by ice formation. This makes it suitable for water extraction operations where the surface is frozen and the ice thickness varies significantly, such as extracting water from seasonally frozen rivers.

[0043] Optionally, the spraying portion 40 has multiple spray ports, spaced apart along the width of the workbench 10 and / or the circumference of the first branch pipe 50. This arrangement of multiple spray ports can improve the spray range and uniformity of the water, further preventing secondary freezing within the water intake area. Furthermore, this arrangement allows for more flexible arrangement of the spray ports to meet diverse usage requirements and working conditions, while also enhancing operator flexibility.

[0044] In this embodiment, the plurality of injection ports are spaced apart along the width direction of the workbench 10 and the circumferential direction of the first branch pipe 50 .

[0045] Optionally, the anti-icing assembly also includes an antifreeze layer. This layer is disposed outside the insulating housing 80 and is made of RPM waterproof and thermally insulating coating. This further enhances the waterproof and thermally insulating properties of the anti-icing device. Furthermore, this configuration provides the anti-icing assembly with excellent waterproof and thermal insulation properties, minimizing the risk of rainwater infiltrating into the main delivery pipe 20 and causing ice to form.

[0046] In this embodiment, the anti-icing device has the following advantages:

[0047] 1) Under non-extreme conditions, such as when the outdoor temperature is above -15°C and the depth of the water intake area is greater than 4m, the anti-icing device can extract river water with a certain temperature (river water temperature is about 4-6°C) 3-6m below the river surface by a disturbance pump, and use the disturbance pump jet disturbance heat exchange method in the specific water intake area to prevent the specific water intake area from re-freezing.

[0048] 2) The anti-icing device can maintain a constant water temperature in the delivery main pipe 20 by turning on the heating belt 70 surrounding the delivery main pipe 20 under extreme conditions, such as when the outdoor temperature is below -15°C and the depth of the water intake area is less than 4m. High-temperature steam is injected into the delivery main pipe 20 through the second branch pipe 60 to increase the temperature of the disturbed water source and achieve temperature compensation for the disturbed water source, thereby solving the problems of rapid decline in heat exchange efficiency as the outdoor temperature drops in extreme weather, low water intake area depth, rapid loss of heat exchange heat, and rapid secondary freezing in specific water intake areas.

[0049] Specifically, the working principle of the anti-icing device is as follows:

[0050] After the river enters its stable closure period, the ice surface in the designated water intake area must first be cleared manually. A work platform 10 is then laid in this area to serve as the initial operating area for the device to prevent secondary freezing in the designated water intake area. The work platform 10 is then installed in the designated water intake area based on the river water level during the closure period. A disturbance pump is hoisted to the end of the work platform 10 away from the riverbank. A main delivery pipe 20 is laid along the work platform 10. A first branch pipe 50 and a second branch pipe 60 are welded to the main delivery pipe 20. The first branch pipe 50 is connected to a spray unit 40 mounted on a floating platform 100, forming an ice-melting system to prevent secondary freezing in the designated water intake area. A heating belt 70 is installed around the main delivery pipe 20, and an insulation layer 90 and an insulation shell 80 are installed on the outer wall of the main delivery pipe 20. The second branch pipe 60 constitutes a temperature compensation and insulation system for the disturbed water area. The second branch pipe 60 is connected to the plant's gas supply pipeline. The steam generated by the plant's steam boiler is injected into the second branch pipe 60 at a regular and quantitative rate to increase the temperature of the disturbed water source and prevent rapid secondary freezing of the specific water intake area when the outdoor temperature is below -15°C in extreme weather and the depth of the water intake area is less than 4m.

[0051] Specifically, the staff controls the anti-icing device according to the outdoor temperature and the water level changes in the water intake area. When the outdoor temperature is higher than -15°C, a disturbance pump is used to extract river water with a certain temperature (the river water temperature is about 4-6°C) 3 to 6 meters below the river. The disturbance pump jet disturbance heat exchange method is used in the specific water intake area to prevent the specific water intake area from refreezing. When the outdoor temperature is lower than -15°C, the efficiency of ice-breaking heat exchange will drop rapidly with the decrease in outdoor temperature, and the ice-breaking area of ​​the specific water intake area will gradually decrease. When the depth of the water intake area is lower than 4m, the heat extracted from the underwater by the submersible pump will quickly disappear in the specific water intake water area. The temperature compensation method is used to solve the problem of the water intake water area that has already broken the ice quickly refreezing.

[0052] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0053] The anti-icing device includes a workbench and an anti-icing assembly. The workbench is installed in the water intake area. The anti-icing assembly includes a main delivery pipe, a pump, a spray unit, a first branch pipe, a second branch pipe, and a control valve. The main delivery pipe is installed on the workbench, and the pump unit is located in the water intake area and is used to pump water into the main delivery pipe. The first ends of the first and second branch pipes are both connected to the main delivery pipe. The second end of the first branch pipe is connected to the spray unit, which is located in the water intake area and sprays water into the water intake area. The second end of the second branch pipe is connected to a steam supply device to supply steam into the main delivery pipe. The control valve is installed on the second branch pipe to control the connection between the second branch pipe and the main delivery pipe and / or the flow rate or flow rate of steam in the second branch pipe. In this way, when water is needed in the water intake area, the ice in the water intake area is first broken to expose the water surface, and then the pump unit is activated to continuously pump water from the water intake area into the main delivery pipe. During the water intake process, water can enter the spray section through the first branch pipe to prevent secondary freezing in the water intake area. At the same time, the second branch pipe can be selected for use based on the environment of the water intake area. If the ambient temperature of the water intake area is low, the control valve can be controlled to open, allowing steam in the steam supply device to enter the main delivery pipe through the second branch pipe. The main delivery pipe then compensates the temperature of the water intake area, allowing the anti-icing device to be used in any environment. This solves the problems of low water intake efficiency and limited water intake conditions in the existing water intake method, thereby improving water intake efficiency.
