Description

Technical Field

[0001] This utility model relates to the technical field of large and medium-sized substations, and in particular to a water tank insulation system for permafrost regions. Background Technology

[0002] In substation design, water is essential for the buildings and transformer fire protection within the substation, making substation water tanks crucial. However, in permafrost regions where temperatures can drop to -40°C or even lower, ensuring the water in the tanks doesn't freeze is critical. Conventional water tank insulation methods involve using thick polystyrene boards or a combination of polystyrene boards and brick walls on the reinforced concrete sidewalls; alternatively, the tank is often built above ground with an external building for insulation, sometimes further enhanced by electric heaters inside. These methods are ineffective and costly in the extremely cold environments of permafrost regions. Utility Model Content

[0003] The present invention provides a water tank insulation system for permafrost regions to prevent the water in the fire-fighting water tank of a substation in permafrost regions from freezing.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] This utility model discloses a water tank insulation system for permafrost regions, comprising a water tank body and a top plate. The top plate covers the top of the water tank body. The pool wall of the water tank body includes a first insulation layer, a conductive concrete layer, a heat insulation layer, and a second insulation layer arranged sequentially from the inside to the outside. A temperature sensor is installed inside the water tank body, and a control device is also included. The temperature sensor and the conductive concrete layer are electrically connected to the control device, and the temperature sensor, the conductive concrete layer, and the control device are electrically connected to an external power supply.

[0006] Furthermore, the temperature sensor is located at the top of the pool wall near the main body of the pool.

[0007] Furthermore, the insulation layer is a 50mm thick concrete insulation layer.

[0008] Furthermore, both the first insulating layer and the second insulating layer are ceramic insulating layers.

[0009] Furthermore, a manhole is provided in the top plate, and an insulating cover is provided in the manhole.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This application discloses a water tank insulation system for permafrost regions. The tank wall is composed of a first insulation layer, a conductive concrete layer, a heat insulation layer, and a second insulation layer, from the inside out. A temperature sensor installed inside the tank monitors the temperature in real time and transmits the monitored temperature to a control device. When the temperature inside the tank reaches a low-temperature threshold (e.g., 0°C) set by the control device, the control device issues an energizing command. The conductive concrete layer is energized, acting as a heating element. When energized, current forms a circuit in the conductive concrete layer, generating heat. The heat spontaneously flows from the high-temperature area to the low-temperature area, flowing to the first insulation layer and raising its temperature. The heat from the first insulation layer flows to the water inside the tank, heating the water. When the temperature inside the tank reaches a high-temperature threshold (e.g., 10°C) set by the control device, the control device... The control equipment issues a power-off command, de-energizing the conductive concrete layer. The control equipment then cycles through energizing and de-energizing the conductive concrete layer, automatically heating the water in the pool to maintain it between a set low-temperature critical value (e.g., 0°C) and a high-temperature critical value (e.g., 10°C), preventing freezing. The insulation layer between the conductive concrete layer and the second insulation layer reduces heat loss to the environment. Most of the heat generated by the energized conductive concrete layer flows to the first insulation layer, causing it to heat up rapidly and simultaneously providing insulation, slowing heat loss and reducing the need for energizing the conductive concrete layer. This results in good insulation performance and low cost. The first and second insulation layers provide better insulation for the conductive concrete layer, preventing safety risks associated with leakage. This water pool insulation system for permafrost regions provides safe, efficient, and low-cost insulation for water in the pool, and is particularly suitable for preventing the water in fire-fighting water pools in substations in permafrost areas from freezing.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1 As shown, this embodiment provides a water tank insulation system for permafrost regions, including a water tank body 1 and a top plate. The top plate covers the top of the water tank body 1. The tank wall of the water tank body 1 includes a first insulating layer 101, a conductive concrete layer 102, a heat insulation layer 103, and a second insulating layer 104 arranged sequentially from the inside to the outside. A temperature sensor 2 is installed inside the water tank body 1. The system also includes a control device. The temperature sensor 2 and the conductive concrete layer 102 are electrically connected to the control device, and the temperature sensor 2, the conductive concrete layer 102, and the control device are electrically connected to an external power supply. The first insulating layer 101 and the second insulating layer 104 are high-density polyethylene insulating layers or ceramic insulating layers. The thickness of the conductive concrete layer 102 is 30mm-50mm, such as 30mm, 40mm, or 50mm. The thickness of the heat insulation layer 103 is 30mm-70mm, such as 30mm, 50mm, or 70mm. The control equipment is a PLC or computer in the substation control room. The electrical connection between the temperature sensor 2, the conductive concrete layer 102 and the control equipment can adopt existing technologies and solutions. The electrical connection between the temperature sensor 2, the conductive concrete layer 102, the control equipment and the external power supply can also adopt existing technologies and solutions. The control equipment receives the temperature information monitored by the temperature sensor 2 and commands the conductive concrete layer 102 to turn on or off. Electrodes can be preset in the conductive concrete layer 102 to form a circuit for energizing.

[0019] A water tank insulation system for permafrost regions based on the above structure comprises a water tank body 1 whose walls are composed of a first insulation layer 101, a conductive concrete layer 102, a heat insulation layer 103, and a second insulation layer 104, from the inside out. A temperature sensor 2 installed inside the water tank body monitors the temperature inside the water tank body 1 in real time and transmits the monitored temperature to a control device. When the temperature inside the water tank body 1 reaches a low-temperature critical value (e.g., 0°C) set by the control device, the control device issues a power-on command, energizing the conductive concrete layer 102. The conductive concrete layer 102 acts as a heating element; when energized, current forms a circuit in the conductive concrete layer 102, generating heat. The heat spontaneously flows from the high-temperature area to the low-temperature area, flowing to the first insulation layer 101, causing it to heat up. The heat from the first insulation layer 101 flows to the water inside the water tank body 1, heating the water. When the temperature inside the water tank body 1 reaches a high-temperature critical value (e.g., 10°C) set by the control device, the control device... When a power-off command is issued, the conductive concrete layer 102 is de-energized. The control equipment instructs the conductive concrete layer 102 to cycle through power-on and power-off cycles, automatically heating the water in the water tank body 1. This keeps the water in the water tank body 1 between the low-temperature critical value (e.g., 0°C) and the high-temperature critical value (e.g., 10°C) set by the control equipment, preventing the water in the water tank body 1 from freezing. The heat insulation layer 103 between the conductive concrete layer 102 and the second insulation layer 104 reduces the flow of heat to the second insulation layer 104 and its loss to the external environment. Most of the heat generated by the conductive concrete layer 102 when energized flows to the first insulation layer 101, causing the first insulation layer 101 to heat up rapidly, quickly heating the water in the water tank body 1. At the same time, it also plays a role in heat preservation, slowing down the heat loss of the water in the water tank body 1, reducing the number of times the conductive concrete layer 102 is energized, resulting in good heat preservation effect and low cost. The arrangement of the first insulation layer 101 and the second insulation layer 104 provides better insulation and isolation for the conductive concrete layer 102, preventing the safety risks caused by leakage. The water tank insulation system of this application provides safe, efficient, and low-cost insulation for the water in the tank body, and is particularly suitable for preventing the water in the fire water tank of the substation in the permafrost region from freezing.

[0020] As one possible implementation method, such as Figure 1 As shown, the temperature sensor 2 is located at the top of the pool wall near the main body of the pool 1.

[0021] If the temperature sensor 2 is fixed by screws or adhesive to the pool wall near the top of the pool body 1, the temperature sensor 2 detects the air temperature above the water in the pool body 1. The air temperature is usually lower than the water temperature in the pool body 1, which better prevents the water in the pool body 1 from freezing.

[0022] As one possible implementation method, such as Figure 1 As shown, the insulation layer 103 is a 50mm thick concrete insulation layer.

[0023] A 50mm thick concrete insulation layer can effectively insulate against heat, preventing the heat generated by the conductive concrete layer 102 from being lost to the external environment through the second insulation layer 104. Furthermore, a foamed concrete insulation layer can be used to further enhance the thermal insulation effect.

[0024] As one possible implementation method, such as Figure 1 As shown, both the first insulating layer 101 and the second insulating layer 104 are ceramic insulating layers.

[0025] The ceramic insulation layer, serving as the first insulation layer 101 and the second insulation layer 104, possesses excellent insulation and corrosion resistance, and its smooth surface makes it resistant to dust accumulation. This makes it suitable for long-term use as an insulation layer for water tanks in substations. Furthermore, a low-temperature resistant ceramic insulation layer can be used to adapt to the low-temperature environment of permafrost regions. The first insulation layer 101 and the second insulation layer 104 can be installed using existing technologies, such as by applying cement mortar or tile adhesive to the corresponding conductive concrete layer 102 and the insulation layer 103 of the concrete insulation layer. For example, a conductive concrete layer 102 can be poured, followed by a concrete insulation layer poured on the outside of the poured conductive concrete layer 102, with the first insulation layer 101 of the ceramic insulation layer laid on the inside of the conductive concrete layer 102, and the second insulation layer 104 of the ceramic insulation layer laid on the outside of the poured concrete insulation layer.

[0026] As one possible implementation, a manhole is provided in the top plate, and the manhole is provided with an insulating cover.

[0027] An insulating cover is placed over the manhole to seal it, reducing heat loss from the water tank body 1 to the outside and further insulating the water inside. The insulating cover also prevents electrical leakage. The manhole is an opening for personnel to enter and exit the equipment for installation, maintenance, and safety inspections. Existing technologies and solutions involve pouring or covering the top of the water tank body 1 with a concrete roof slab. The roof slab can be made of foamed concrete, which provides better insulation for the water inside the water tank body 1, reduces the electrical conductivity of the conductive concrete layer 102, and lowers costs.

[0028] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
