Description

Technical Field

[0001] This utility model relates to the field of meteorological observation auxiliary equipment technology, and more specifically, to an electrothermal ice-collecting device used in icing observation experiments. Background Technology

[0002] In many fields such as power and meteorology, icing observation experiments are an important part of obtaining icing-related data and carrying out research. By sampling and analyzing the icing on simulated conductors, we can gain a deeper understanding of the characteristics and patterns of icing, providing a basis for related research and practice.

[0003] Currently, in icing observation experiments, the mainstream manual ice removal method mainly relies on physical tools such as scrapers and choppers. However, these traditional ice removal methods have many significant drawbacks and cannot meet the experimental requirements for sampling quality and efficiency. Taking rime ice sampling as an example, rime ice is formed by the freezing of supercooled raindrops and has extremely high adhesion, reaching 10-30 N / cm², forming a dense and hard ice layer on the surface of the conductor. When using traditional tools, it is necessary to chop vigorously to break the ice layer. This not only causes debris to fly due to the impact, affecting the operational safety of the sampling personnel, but also reduces the collection rate to only 80%-90%, thus seriously affecting the measurement accuracy of key data such as rime ice weight and density.

[0004] Sampling rime presents another challenge. Rime is formed by the sublimation of water vapor, exhibiting a loose and porous structure with an adhesion strength of only 1-5 N / cm². When the cutting tool comes into contact with rime, the resulting vibration can easily cause the ice in non-sampling sections to detach partially or completely, failing to meet the integrity requirements for subsequent observation and sampling. Furthermore, due to irregular edges in the sampling section and some ice falling outside the ice collection bucket due to vibration, the complete sampling rate is also less than 85%, introducing significant uncertainty into the accuracy of experimental data.

[0005] Although a small number of heating-assisted ice-harvesting devices exist in the current technology, most of these devices have several problems that limit their widespread application in field observation scenarios. On the one hand, some heating devices have complex structures, such as integrated hydraulic systems, which not only increases the cost and maintenance difficulty of the device but also reduces its reliability and portability in complex field environments. On the other hand, some heating devices have low heating efficiency, with heating times exceeding 5 minutes, making it difficult to quickly and effectively harvest ice and meet the needs of experimental data collection in a timely manner. Furthermore, most of these existing heating-assisted devices have not been designed with differentiated solutions for the different physical characteristics of rime or hoarfrost, failing to fully utilize the advantages of heating for ice harvesting to adapt to the sampling requirements of different types of icing.

[0006] In summary, existing methods for manually collecting ice in icing observation experiments have numerous problems and limitations. Neither traditional physical tools nor existing heating-assisted devices can efficiently and accurately obtain ice samples that meet experimental requirements. Therefore, there is an urgent need for a novel ice-collecting device that can overcome these shortcomings, thereby improving the efficiency and quality of icing observation experiments and providing more reliable data support for related research in fields such as power and meteorology.

[0011] An electric heating bracket, wherein the electric heating element is fixedly assembled to the electric heating bracket and forms an electric heating cutting part under the constraint of the electric heating bracket, wherein the electric heating cutting part is an electric heating cutting line or an electric heating cutting surface;

[0012] A handle connected to an electric heating bracket, the handle having a gripping part, the gripping part and the electric heating cutting part maintaining at least a first distance;

[0014] The electrothermal ice-collecting device applied to icing observation experiments according to the above-described technical solution of this utility model may also have the following additional technical features:

[0015] In the above technical solution, the electric heating bracket includes:

[0016] Support body;

[0017] A support rod is connected at one end to the main body of the support and at the other end to the heating element. The support rod creates a gap between the heating element and the main body of the support to form an ice sample channel. When the heating cutting part moves along the direction of the ice-covered material, the cut ice sample passes through the ice sample channel.

[0018] In the above technical solution, the number of support rods is at least two, and the heating element is located between two adjacent support rods so that the ice-like channel is located between two adjacent support rods.

[0019] In the above technical solution, the heating element is connected to the support rod through a ceramic insulating terminal.

[0020] In the above technical solution, the electrothermal cutting part includes at least:

[0021] The first heating section is arranged along the first direction;

[0025] One end of the first heating section is connected to the first support rod, and the other end is connected to the second support rod;

[0027] The above technical solution also includes:

[0028] An auxiliary handle is provided on the electric heating bracket.

[0029] In the above technical solution, the handle and / or auxiliary handle glove are provided with a non-slip silicone layer.

[0030] In the above technical solution, the handle is provided with:

[0031] A control switch is used to control the connection or disconnection of the circuit between the heating element and the power source.

[0032] A temperature control switch is used to control the output power of the heating element through preset levels. Under different output power levels, the heating element has a corresponding output temperature to cut different types of icing.

[0033] In the above technical solution, the power source includes a storage battery.

[0034] In summary, due to the adoption of the above-mentioned technical features, the beneficial effects of this utility model are:

[0035] This invention provides a compact, temperature-controlled electrothermal ice-collecting device that achieves complete sampling of ice-covered wires through thermal cutting technology. The fragmentation rate of rime ice sampling is ≤10%, the sample collection rate is ≥95%, and the retention rate of complete morphology of hoarfrost sampling is ≥85%. The device is easy to operate, heats up quickly, and fully meets the needs of rapid and accurate sampling in the field.

[0036] Specifically, this electrothermal ice-collecting device uses an electrothermal cutting section to release heat, breaking the adhesion of the ice layer interface. This allows for rapid cutting and sampling of the ice layer. Compared to traditional physical knives and some existing heating devices, it significantly improves sampling efficiency and effectively shortens sampling time. Especially when sampling rime ice, it eliminates the need for vigorous chopping, avoiding the problems of flying debris and low collection rates caused by impact. When sampling hoarfrost ice, it reduces the occurrence of ice falling off non-sampling sections due to knife vibration and uneven edges of the sampling section, improving the complete sampling rate and making sampling more efficient and convenient.

[0037] The device is designed to address the different physical characteristics of rime and hoarfrost. The heating element converts electrical energy into heat when powered by an electric source. Temperature control switches at different settings regulate the output power of the heating element, thus adapting to different types of icing sampling requirements. For example, for rime with high adhesion, an appropriate setting can be selected to increase the output power and temperature of the heating element, enhancing its cutting ability; for hoarfrost with low adhesion and loose texture, the output power can be appropriately reduced to avoid overheating and damaging the ice sample. This improves the device's adaptability to different types of icing sampling and meets the requirements of various experimental scenarios.

[0038] The heating element is fixedly mounted on the heating bracket, forming the heating cutting section. It maintains at least a first gap from the handle's grip area. This structural design ensures operational stability and avoids the risk of burns to operators during sampling due to close proximity to the heating cutting section, thus improving safety. Simultaneously, the ice sample channel design of the heating bracket allows the cut ice sample to pass smoothly, facilitating ice sample collection. Furthermore, the auxiliary handle and the anti-slip silicone layer on the handle and auxiliary handle gloves further enhance operational stability and convenience, making the device more user-friendly.

[0039] In summary, this electrothermal ice-collecting device has many beneficial effects, such as high efficiency sampling, strong adaptability, reasonable structure and convenient use, energy saving and environmental protection, low cost and easy maintenance, and high portability. It can effectively solve the problems existing in the manual ice-collecting method in the current ice-collecting observation experiment, greatly improve the quality and efficiency of ice-collecting sampling, and provide strong technical support for ice-collecting observation research in the fields of power and meteorology.

[0048] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0049] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0050] The following reference Figure 1 This invention describes an electrothermal ice-collecting device for ice-covering observation experiments, provided according to some embodiments of the present invention.

[0051] Some embodiments of this application provide an electrothermal ice-collecting device for use in icing observation experiments.

[0052] like Figure 1 As shown, the first embodiment of this utility model proposes an electrothermal ice-collecting device for ice-covering observation experiments, which includes at least an electrothermal element 1, an electrothermal support 2, and a handle 3.

[0053] The heating element 1 is connected to a power source to convert electrical energy into heat energy. The power source can be an external power source or a rechargeable battery. In one specific embodiment, the power source is a 12V / 20AH battery built into the electric heating ice-removing device, which can be used for continuous operation.

[0054] The heating element 1 is fixedly assembled to the heating bracket 2 and forms an electrothermal cutting part under the constraint of the heating bracket 2. The electrothermal cutting part is an electrothermal cutting line or an electrothermal cutting surface. The electrothermal cutting part is preferably a linear structure to facilitate cutting. In a specific embodiment, the heating element 1 is a heating wire, specifically a Φ0.8mm Cr20Ni80 nickel-chromium alloy wire (Cr: 20.0~23.0%, Ni: 75.5%).

[0055] The handle 3 is connected to the electric heating bracket 2. The handle 3 has a gripping part 31. The gripping part 31 and the electric heating cutting part are at least separated by a first gap. It can be understood that the first gap keeps the operator's hand at a safe distance from the high temperature area. In a specific embodiment, the first gap is not less than 200mm.

[0056] The electrothermal cutting section is used to contact the ice layer interface and release heat to break the adhesion of the ice layer interface, thereby cutting and sampling the ice according to the target shape.

[0057] In some embodiments, the electric heating bracket 2 includes a bracket body 21 and a support rod. The bracket body 21 can be integrally formed with the support rod or can be separately fixed from the support rod.

[0058] The support body 21 can be made of alloy material, which has high rigidity to serve as the main support. One end of the support rod is connected to the support body 21, and the other end is connected to the heating element 1. The support rod creates a gap between the heating element 1 and the support body 21 to form an ice sample channel 25. When the electrothermal cutting part moves along the direction of the ice-covered material arrangement, the cut ice sample passes through the ice sample channel 25.

[0059] In some embodiments, the number of support rods is at least two, and the heating element 1 is located between two adjacent support rods so that the ice-like channel 25 is located between two adjacent support rods.

[0060] In some embodiments, the heating element 1 is connected to the support rod via a ceramic insulating terminal 26.

[0061] In some embodiments, the electrothermal cutting section includes at least a first heating segment 11 and a second heating segment 12. The first heating segment 11 is arranged along a first direction; the second heating segment 12 is arranged along a second direction; the first and second directions are perpendicular to each other. The perpendicular arrangement of the first heating segment 11 and the second heating segment 12 allows the other heating segment to act as an auxiliary force on the other perpendicular plane while one of them travels along the cutting direction, simultaneously breaking the adhesion of the ice layer interface.

[0062] In one specific embodiment, the support rod includes a first support rod 22, a second support rod 23, and a third support rod 24; one end of the first heating section 11 is connected to the first support rod 22, and the other end is connected to the second support rod 23; one end of the second heating section 12 is connected to the second support rod 23, and the other end is connected to the third support rod 24. This provides two ice-collecting channels, accommodating ice-collecting operations from different directions.

[0063] In some embodiments, the ice-removing device further includes an auxiliary handle 4, which is disposed on the electric heating bracket 2. The auxiliary handle 4 and the handle 3 work together to achieve stable gripping and stable cutting of the ice-removing device. Of course, for the purposes of this disclosure, even without the auxiliary handle 4, the operator can still operate the device with one hand using the handle 3.

[0064] More specifically, the aforementioned auxiliary handle 4 and handle 3 are designed according to ergonomic standards, with an elliptical cross-section for easier gripping. In one specific embodiment, an anti-slip silicone layer can also be fitted onto the handle 3 and auxiliary handle 4 to provide heat insulation and anti-slip properties. For example, a 3mm thick anti-slip silicone layer can be used to keep the surface temperature of the handle 3 below the human safety threshold (43°C). Of course, the anti-slip silicone layer can also serve as insulation to prevent electric shock hazards in case of leakage.

[0065] In some implementations, the handle 3 is equipped with a control switch 32 and a temperature control switch 33.

[0066] The control switch 32 is used to control the circuit connection between the heating element 1 and the power supply; the temperature control switch 33 is used to control the output power of the heating element 1 through a preset level. Under different output power levels, the heating element 1 has a corresponding output temperature to cut different types of icing.

[0067] Specifically, the control switch 32 can be a touch switch, connected in series between the heating element 1 and the power supply. To simplify the circuit structure, the connecting wire 5 between the heating element 1 and the power supply can be connected to the power supply after passing through the heating bracket 2 and the handle 3. The control switch 32 is integrated into the grip part 31 of the handle 3 and has RGB status indicator lights (red for heating, green for standby, and off for power-off), meeting the IP65 protection rating.

[0068] The temperature control switch 33 can be a rotary switch to adjust the power of the circuit in multiple levels. The power adjustment can be achieved by setting a PWM pulse width modulation module to adjust the duty cycle, thereby regulating the temperature of the heating element 1.

[0069] In one specific embodiment, the temperature control switch 33 has two adjustment levels: the first level is 260 (±15)℃, which is suitable for cutting rime ice; the second level is 150 (±15)℃, which is suitable for cutting hoarfrost.

[0070] Protective covers 34 can be installed on both control switch 32 and temperature control switch 33 to prevent dust, water, and accidental contact. Protective corrugated tubing can be fitted onto the connecting wire 5 for protection.

[0071] The electric heating ice-removing device disclosed herein is used as follows:

[0072] 1. High-efficiency ice cutting mode: Set the temperature control knob to 260℃. The heating element 1 heats up to the target temperature within 20 seconds. The high temperature of the heating element 1 quickly melts the ice layer interface, breaking the adhesion and pulling at a uniform speed to achieve continuous cutting without impact. The detached ice blocks can fall completely into the ice-covering bucket below. This operation method produces almost no debris, and the ice is collected completely.

[0073] 2. Flexible sampling mode for rime ice: Select the 150℃ low temperature setting, slowly bring the heating element 1 close to the ice-covered body until the melted ice thickness contacts the surface of the wire, then slowly pull the handle 3 along the wire to cut steadily at a speed of 2-5cm / s. The ice block will fall through the ice-collecting channel and fall into the ice-covered bucket below after the cutting is completed.

[0074] In this specification, the illustrative expressions of the terms used do not necessarily refer to the same embodiments or examples. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0075] Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model shall be included within the protection scope of this utility model.
