Description

Technical Field

[0001] The embodiments disclosed herein belong to the field of battery insulation technology, specifically relating to a battery insulation device and system suitable for high-altitude pipeline valve chambers. Background Technology

[0002] To ensure the reliable and stable operation of oil and gas pipelines, the solar-powered monitoring valve chamber uses battery banks as backup power, serving as the last line of defense for the power supply system and playing a decisive role in critical moments. In high-altitude environments, the battery, as a key component, significantly impacts the reliability of the solar-powered monitoring valve chamber during operation.

[0003] Temperature is the most significant factor affecting the normal operation of a battery. When a battery is exposed to low temperatures for an extended period, the heat released by an uninsulated battery is far from sufficient to raise the ambient temperature. This results in the battery failing to reach its rated charge during the charging process, or even being tripped by protection mechanisms and unable to discharge further. Simultaneously, low temperatures increase the battery's internal resistance during charging, prolonging charging time and potentially preventing it from fully charging. Effective insulation measures can optimize the charging process, shorten charging time, and improve battery charging efficiency. Therefore, maintaining the optimal operating temperature of the battery is crucial.

[0004] In existing technologies, the following methods are typically used to ensure battery capacity.

[0005] 1) Increase the capacity of the battery to cope with the decline in battery performance in low-temperature environments, but this will increase cost and weight.

[0006] 2) Improve the power generation efficiency of solar panels to provide more power reserves for batteries; however, this requires high technical and cost requirements.

[0007] 3) Use battery types that are more resistant to low temperatures, but these batteries are often expensive and offer limited performance improvements.

[0008] 4) Using heating equipment such as air conditioners and electric heaters to keep the batteries warm is a common practice in areas with good external power supply. However, high-altitude oil and gas pipeline valve chambers, which are difficult to reach with mains power, usually use solar power systems to monitor the valve chambers. If HVAC equipment is used, it will inevitably increase the area of ​​the solar panels and the capacity of the batteries.

[0009] Therefore, how to solve the above-mentioned technical problems has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

Detailed Implementation

[0035] To enable those skilled in the art to better understand the technical solutions of this disclosure, the disclosure will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] The embodiments of this application will be further described in detail below with reference to the accompanying drawings and examples. The detailed descriptions and accompanying drawings of the following embodiments are used to exemplarily illustrate the principles of this application, but should not be used to limit the scope of this application; that is, this application is not limited to the described embodiments. In the description of this application, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," etc., indicating orientation or positional relationships are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. "Vertical" is not strictly vertical, but within the allowable error range. "Parallel" is not strictly parallel, but within the allowable error range.

[0037] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application depending on the specific circumstances.

[0038] The main characteristics of high-altitude environments include: low air pressure, thin air, low oxygen content, long periods of low temperature, large diurnal temperature range, long hours of sunshine, strong ultraviolet radiation, and dry climate. Batteries are a crucial component of solar-powered monitoring valve chambers, as all electrical equipment inside these chambers relies entirely on solar energy for power after a power outage. Therefore, battery performance has a vital impact on the operational performance of the solar-powered monitoring valve chamber. Low temperatures significantly affect battery charging and discharging performance. When the electrolyte temperature decreases, the reactivity of both solid and liquid phase active materials in lead-acid batteries decreases, viscosity increases, diffusion rate slows, resistance increases, and ion movement is significantly hindered, greatly slowing the electrochemical reaction rate. A dense passivation film easily forms on the positive and negative electrodes, thus limiting the discharge process. The diffusion coefficient and conductivity of sulfuric acid electrolytes decrease at low temperatures, leading to a reduction in charging and discharging rates and efficiency. At low temperatures, the electrolyte also undergoes solidification from the liquid phase to the solid phase. Hydrogen evolution at the negative electrode is exacerbated under low-temperature charging conditions. To achieve a higher state of charge, the water loss during charging is significant, thus reducing charging efficiency. Particularly at low temperatures, the viscosity of sulfuric acid increases significantly with decreasing temperature, leading to a significant decrease in battery capacity. A drop in temperature from 25°C to -40°C can reduce the capacity of lead-acid batteries by an average of about one-third of its original capacity. During charging, the solubility and dissolution rate of lead sulfate decrease at low temperatures, restricting the pre-charging process. The diffusion coefficient and conductivity of the sulfuric acid electrolyte also decrease at low temperatures, resulting in a reduction in charge / discharge rates and efficiency. At low temperatures, the electrolyte also undergoes solidification from the liquid phase to the solid phase. Hydrogen evolution at the negative electrode is exacerbated under low-temperature charging conditions. To achieve a higher state of charge, the water loss during charging is significant, thus reducing charging efficiency.

[0039] In low-temperature regions, such as high-altitude areas, the most significant environmental characteristics are low temperatures and large diurnal temperature variations, with an annual temperature difference of 10°C to 20°C and a maximum temperature difference of up to 30°C. Nighttime lows can reach -40°C. Batteries operate normally at an ambient temperature of around 25°C. However, when the temperature drops below this level, the micropores of the negative electrode lead plate inside the battery easily freeze, forming a dense layer of lead sulfate. Simultaneously, the diffusion rate of the electrolyte within the blocked micropores slows down, and the battery capacity decreases with decreasing temperature. Therefore, the lower the temperature, the more severe the micropore blockage, the lower the utilization rate of active materials, and the more severe the passivation of the battery, ultimately leading to premature discharge termination.

[0040] In view of the problem of battery performance degradation caused by high altitude conditions, this invention aims to solve the problem of significant performance degradation of batteries in high-altitude pipeline valve chambers due to low-temperature environments. By designing a special insulation device and unique technical methods, a suitable battery temperature is maintained, ensuring stable power supply under harsh high-altitude conditions and improving the operational reliability of the valve chamber.

[0041] like Figure 1-2 As shown, a battery insulation device 100 suitable for high-altitude pipeline valve chambers is provided. The insulation device includes an outer shell 1, a temperature control layer 2, a first insulation layer 3, and a first heat reflective layer 4.

[0042] The temperature control layer 2 is disposed on the inner wall side of the outer shell 1, and the first insulation layer 3 is disposed on the side of the temperature control layer 2 away from the outer shell 1. The insulation device also includes a first heat reflective layer 4 sandwiched between the inner wall of the outer shell 1 and the temperature control layer 2, sandwiched between the temperature control layer 2 and the first insulation layer 3, and disposed on the surface of the first insulation layer 3 away from the temperature control layer 2.

[0043] In this invention, by sandwiching a first heat-reflective layer 4 between the inner wall of the outer shell 1 and the temperature control layer 2, and between the temperature control layer 2 and the first insulation layer 3, and by setting the first heat-reflective layer 4 on the surface of the first insulation layer 3 facing away from the temperature control layer 2, the requirements for low-temperature resistance, fire resistance, and waterproofing in high-altitude environments can be met. Since the first heat-reflective layer 4 can reflect heat, it can maximize the heat transfer to the entire outer shell 1, making it suitable for batteries operating in low-temperature environments.

[0044] Furthermore, the device is equipped with a first heat-reflective layer 4, which can ensure the heat transfer effect inside the outer casing 1, maintain the overall temperature inside the first insulation layer 3 of the battery, and meet the operating temperature requirements of the battery.

[0045] In some embodiments, the outer casing 1 includes a steel casing and a zinc layer disposed on the surface of the steel casing.

[0046] Specifically, the outer casing 1 of the battery insulation device 100 is made of galvanized steel sheet. Galvanized steel sheet is a welded steel sheet with a hot-dip galvanized or electro-galvanized layer on its surface, forming a physically protective zinc layer on the steel sheet surface. In a corrosive environment, the galvanized layer will corrode first, and then the base material (steel shell). Zinc acts as a negative potential sacrificial anode, protecting the base steel sheet from corrosion, thereby inhibiting the corrosion of the base material. In addition, the galvanized steel shell is well-suited for applications in high-altitude areas with thin air, low oxygen content, large temperature differences, and strong ultraviolet radiation.

[0047] In other embodiments, the outer casing 1 is rectangular and is surrounded by six plates on the top, bottom, left, right, front, and back. The six plates are thickened to form a surrounding insulation for the battery inside the outer casing 1, thereby further reducing heat loss.

[0048] In some embodiments, the first insulation layer 3 is made of cross-linked polyethylene foam.

[0049] To improve the battery's performance at low temperatures, a first insulation layer 3 is wrapped around the battery. This first insulation layer 3 is made of cross-linked polyethylene foam, which is produced by continuous high-temperature foaming of low-density polyethylene resin with a cross-linking agent and a foaming agent. Compared to other polyethylene materials, cross-linked polyethylene foam has a lower thermal conductivity and superior low-temperature resistance. During charging and discharging, the battery releases a significant amount of heat. The cross-linked polyethylene foam effectively prevents external air from entering, isolating the heat released by the battery within its interior. It exhibits excellent performance in terms of insulation, durability, and flame retardancy.

[0050] In some embodiments, the material of the first heat-reflective layer 4 includes aluminized reflective cotton.

[0051] In this invention, the first heat-reflective layer 4 is a heat-reflective spacer material within the battery insulation device 100, which can effectively improve the overall heat preservation performance of the insulation device. The first heat-reflective layer 4 is made of aluminized reflective cotton, which can reflect the radiated heat from the heating element upwards, effectively reducing the downward heat loss, increasing the heating rate, ensuring a constant overall temperature, and effectively isolating it from oxygen and moisture. The high heat reflection rate and heating rate of the first heat-reflective layer 4 can also quickly transfer heat throughout the entire battery insulation device 100, thus delaying heat dissipation and extending the insulation period.

[0052] refer to Figure 3 In some embodiments, the temperature control layer 2 includes a first electrothermal film 21 and a thermistor sensor 22. The first electrothermal film 21 is sandwiched between two first heat reflective layers 4. The thermistor sensor 22 is used to detect the temperature inside the outer casing 1. The working state of the first electrothermal film 21 is controlled according to the temperature detected by the thermistor sensor 22.

[0053] In some embodiments, the first electrothermal film 21 comprises a graphene electrothermal film.

[0054] In some embodiments, the resistance temperature sensor 22 includes a platinum resistance temperature sensor 22.

[0055] The temperature control layer 2 of the battery insulation device 100 mainly functions to control the heat generation so that the temperature inside the outer shell 1 of the insulation device reaches the preset requirement. The temperature control layer 2 consists of a first electrothermal film 21 and a thermal resistance sensor 22. The first electrothermal film is a film structure that generates heat when electricity is applied. Through electric heating, heat is transferred to the space by radiation. It has high conversion efficiency and its effect is better than traditional convection heating methods.

[0056] The resistance temperature detector (RTD) sensor 22 features a large temperature coefficient of resistance, good linearity, stable performance, a wide operating temperature range, and ease of manufacturing. It measures temperature by utilizing the characteristic that the resistance of a conductor changes with temperature, and then transmits the data to a backend system. It offers high measurement accuracy, can be applied to a wide range of measurements, and is particularly effective at low temperatures. It is easy to use in automated and long-distance measurement applications.

[0057] Considering the functional requirements of the battery insulation device 100 for temperature control, as well as the fire safety and operational safety requirements of the entire oil and gas pipeline station, the temperature control layer 2 adopts a graphene electrothermal film. This graphene material is a single layer of carbon atoms grown through chemical vapor deposition; it is transparent and safe, and its electrothermal conversion efficiency is relatively high among all electric heating elements, with almost no other form of energy loss during the energy conversion process. Compared to resistance wire electrothermal films, which suffer from uneven heating and the risk of burns due to localized overheating, and carbon crystal electrothermal films, which are prone to aging and suffer from severe thermal efficiency degradation, graphene electrothermal film has a wider range of applications. Furthermore, compared to copper resistance temperature detectors (RTDs), which are easily oxidized and require external protective sheaths, the RTD sensor 22 uses a platinum RTD sensor with higher accuracy in low-temperature environments.

[0058] In some embodiments, the heat preservation device further includes a second heat reflective layer 5, a second heat preservation layer 6, and a second electrothermal film 7. The second heat reflective layer 5 is disposed at a distance from the side of the first heat reflective layer 4 opposite to the first heat preservation layer 3, the second heat preservation layer 6 is disposed on the surface of the second heat reflective layer 5 opposite to the first heat reflective layer 4, and the second electrothermal film 7 is disposed on the surface of the second heat preservation layer 6 opposite to the second heat reflective layer 5.

[0059] In this invention, the second heat-reflective layer 5 can further reflect heat and reduce heat loss. Working synergistically with the first heat-reflective layer 4, it greatly improves the overall heat insulation effect of the insulation device. Furthermore, the second heat-reflective layer 5 and the first heat-reflective layer 4 are spaced apart, which effectively enhances the heat insulation effect and is beneficial for heat preservation inside the outer casing 1. The introduction of the second electrothermal film 7 makes the temperature control system more flexible, allowing for more precise adjustment of the internal temperature according to actual needs, ensuring that the battery operates within the optimal temperature range, thereby extending the battery's lifespan and performance stability.

[0060] Furthermore, by adding a second insulation layer 6, the influence of the external environment on the internal temperature can be effectively blocked, reducing the energy consumption required to maintain a suitable temperature and improving the energy utilization efficiency of the entire insulation device.

[0061] In some embodiments, the material of the second heat reflective layer 5 includes aluminized reflective cotton, the material of the second insulation layer 6 includes cross-linked polyethylene foam, and the material of the second electrothermal film 7 includes graphene electrothermal film.

[0062] In this invention, the second heat-reflective layer 5 is a heat-reflective spacer material within the battery insulation device 100, which can effectively improve the overall heat preservation performance of the insulation device. The second heat-reflective layer 5 is made of aluminized reflective cotton, which can reflect the radiated heat from the heating element upwards, effectively reducing the downward heat loss, increasing the heating rate, ensuring a constant overall temperature, and effectively isolating it from oxygen and moisture. The high heat reflection rate and heating rate of the second heat-reflective layer 5 can also quickly transfer heat throughout the entire battery insulation device 100, thus delaying heat dissipation and extending the insulation period.

[0063] In some embodiments, the second insulation layer 6 is made of cross-linked polyethylene foam.

[0064] To improve the battery's performance at low temperatures, a second insulation layer 6 is further wrapped around the battery. This second insulation layer 6 is made of cross-linked polyethylene foam, which is produced by continuous high-temperature foaming of low-density polyethylene resin with a cross-linking agent and a foaming agent. Compared to other polyethylene materials, cross-linked polyethylene foam has a lower thermal conductivity and superior low-temperature resistance. During charging and discharging, the battery releases a significant amount of heat. The cross-linked polyethylene foam effectively prevents external air from entering, isolating the heat released by the battery within its interior. It exhibits excellent performance in terms of insulation, durability, and flame retardancy.

[0065] This invention provides a specific example, including:

[0066] The heat preservation device of this invention comprises an outer shell 1, a first heat preservation layer 3, a second heat preservation layer 6, a first heat reflective layer 4, a second heat reflective layer 5, a temperature control layer 2, and a second electrothermal film 7. The outer shell 1 is made of galvanized steel sheet. The first heat preservation layer 3 and the second heat preservation layer 6 are made of cross-linked polyethylene foam material, which is continuously foamed at high temperature with low-density polyethylene resin, a cross-linking agent, and a foaming agent. The first heat reflective layer 4 and the second heat reflective layer 5 are made of aluminized heat reflective cotton. The temperature control layer 2 is composed of an electrothermal film and a thermal resistance sensor.

[0067] The battery insulation system 200 includes a controller 8 electrically connected to a thermistor sensor 22. The insulation system can accurately monitor and regulate the temperature inside the casing 1, maintaining it within an optimal range of 10°C to 30°C. In use, the battery is placed inside the casing 1. When the temperature falls below the set lower limit, the controller 8 controls the operation of the heating films (first heating film 21 and second heating film 7) based on the comparison between the temperature collected by the thermistor sensor 22 and the preset temperature. Heating stops when the temperature inside the casing 1 reaches the upper limit.

[0068] In this invention, the precise control of the heating film through the insulation system ensures the insulation effect inside the outer shell 1, avoids energy waste and overheating risks, and ensures the stable operation of the battery in the valve chamber of the high-altitude pipeline.

[0069] The second specific example provided by the present invention includes:

[0070] The outer shell 1 of the insulation device is rectangular and consists of six plates arranged in a hexahedral structure, with each plate made of galvanized steel for good mechanical strength and corrosion resistance. The first insulation layer 3 and the second insulation layer 6 are made of cross-linked polyethylene foam material, which is continuously foamed at high temperature using low-density polyethylene resin, cross-linking agent, and foaming agent, and are tightly bonded to the inner wall of the box. The thermal resistance sensor 22 is used to monitor the real-time temperature inside the outer shell 1 and feed it back to the controller 8. The controller 8 controls the opening and closing of the relay based on the comparison between the real-time temperature and the preset temperature, according to the preset temperature range of 10℃-30℃, thereby achieving precise control of the working state of the electric heating film (first electric heating film 21 and second electric heating film 7).

[0071] In this invention, the precise control of the heating film through the insulation system ensures the insulation effect inside the outer shell 1, avoids energy waste and overheating risks, and ensures the stable operation of the battery in the valve chamber of the high-altitude pipeline.

[0072] refer to Figure 4 A second aspect of the embodiments of this disclosure provides a battery insulation system 200 suitable for high-altitude pipeline valve chambers. The system includes the aforementioned battery insulation device 100 suitable for high-altitude pipeline valve chambers, comprising a controller 8, a communication module 9, and a display and operation module 10.

[0073] The controller 8 is electrically connected to the first heating film 21, the second heating film 7 and the resistance temperature detector 22 respectively. The controller 8 controls the working state of the first heating film 21 and the second heating film 7 according to the temperature detected by the resistance temperature detector 22.

[0074] The communication module 9 and the display and operation module 10 are respectively connected to the controller 8 and the display and operation module 10. The display and operation module 10 is used to control the controller 8 through the communication module 9.

[0075] Specifically, the controller 8 controls the working state of the first heating film 21 and the second heating film 7 based on the comparison and analysis results of the temperature data collected by the resistance temperature sensor 22 and the preset temperature, so as to regulate the temperature inside the outer shell 1.

[0076] In some embodiments, the insulation system also includes a refrigeration module disposed on the housing 1.

[0077] Specifically, the controller 8 controls the first heating film 21 and / or the second heating film 7 to perform heating based on the comparison results, or controls the refrigeration module to perform cooling operations. The heating element can also be a resistance wire or a ceramic heater, and the refrigeration module includes an air-cooled device or a liquid-cooled device, wherein the air-cooled device includes a fan.

[0078] The controller 8 communicates with the display and operation module 10 through the communication module 9, so that the display and operation module 10 can intuitively display the current temperature collected by the thermal resistance sensor 22 and the working status of the thermoelectric film, and provide a user operation interface to facilitate the setting of parameters such as temperature threshold and working mode.

[0079] In some embodiments, the insulation system also includes a power management module and a data storage unit. The power management module supplies power to the controller 8, communication module 9, display and operation module 10, and data storage unit.
