Description

Technical Field

[0001] This utility model belongs to the field of snow melting agent testing technology, specifically relating to a real-time dynamic evaluation device for snow melting agent performance. Background Technology

[0002] With the intensification of winter climate change, snow and ice weather has had a significant impact on transportation, road safety, and urban infrastructure. To ensure smooth traffic flow and safety, the application of de-icing agents has become a crucial measure to address snow and ice accumulation. De-icing agents can accelerate the melting of snow and ice, reducing the impact of snow and ice on vehicle movement and pedestrian travel. Currently, snow removal personnel use on-site assessments to select de-icing agents suitable for local conditions, thereby improving their effectiveness.

[0003] However, the performance evaluation of de-icing agents mainly relies on laboratory tests and static environmental simulations. These traditional evaluation methods often fail to reflect the actual performance of de-icing agents under different environmental conditions in real time, especially in complex and variable road environments. Temperature, in particular, directly affects the effectiveness of de-icing agents. Furthermore, traditional evaluation methods often overlook various external conditions that de-icing agents may encounter in practical applications, such as changes in the distribution of de-icing agents after vehicle compaction and the consumption of de-icing agents during application.

[0004] Therefore, there is an urgent need for a device capable of real-time monitoring and dynamic evaluation of de-icing agent performance, which can accurately assess the effectiveness of de-icing agents under different climatic conditions. This will not only help to scientifically guide the rational use of de-icing agents and optimize their formulation and application strategies, but also provide real-time data support for road management departments, thereby improving road maintenance efficiency and reducing traffic accident rates. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a real-time dynamic evaluation device for the performance of snow melting agents.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A real-time dynamic evaluation device for de-icing agent performance includes a low-temperature test chamber, a main control computer located on one side of the low-temperature test chamber, and a vacuum pump located on the other side for drawing a vacuum inside the low-temperature test chamber; a transparent platform for placing samples is located on one side of the low-temperature test chamber, and a photographing device for photographing the samples and de-icing agent inside the transparent platform is located on the other side; a de-icing agent spraying device for dripping de-icing agent is fixedly installed on the top of the low-temperature test chamber, above the transparent platform; the photographing device, the de-icing agent spraying device, and the vacuum pump are all electrically connected to the main control computer.

[0008] Specifically, the transparent stage is provided with multiple rows and columns of blind holes of the same depth along the vertical direction. The diameter of each row of blind holes is the same, while the diameter of each column of blind holes is different. Each row of blind holes is perpendicular to the shooting direction of the shooting device.

[0009] Specifically, each of the blind holes is provided with a test tube that matches its size and is used to place the sample.

[0010] Specifically, the de-icing agent spraying device includes de-icing agent spraying components adapted to the number of blind holes in each row. Each de-icing agent spraying component includes a de-icing agent solution storage tank, a high-pressure pump, a delivery pipe, and a nozzle. The de-icing agent solution storage tank is connected to the nozzle through the high-pressure pump and the delivery pipe. Each delivery pipe and nozzle is fixed by a nozzle fixing plate. The de-icing agent solution storage tank and the nozzle fixing plate are both fixed to the inner top of the low-temperature test chamber. The high-pressure pump is electrically connected to the main control computer.

[0011] Specifically, the transparent stage is made of epoxy resin or acrylic, and the outer circumference of the transparent stage is engraved with scale lines to facilitate reading the liquid level in the blind hole.

[0012] Specifically, the vacuum pump is connected to the low-temperature test chamber via a pump pipe and is fixed outside the low-temperature test chamber by a pump support frame.

[0013] Specifically, the shooting device includes a high-precision camera that collects video information and thermal imaging temperature information. When turned on, it can reflect the snow melting process in real time on a computer, monitor the changes in snow or ice, measure the changes in snow layer thickness in real time, and measure the temperature changes during the snow melting process in real time.

[0014] Specifically, the low-temperature test chamber is also equipped with an observation window, which is detachably and sealed to the low-temperature test chamber through a sealing frame.

[0015] Specifically, the sealing frame is connected to the low-temperature test chamber by bolts.

[0016] Specifically, a sealing silicone sealant is provided between the sealing frame and the low-temperature test chamber.

[0017] It should be noted that the main control computer is electrically connected to the shooting device, vacuum pump, and high-pressure pump via cables. When the cables pass through the low-temperature test chamber, they are all sealed to the low-temperature test chamber. The pump pipe is connected to the low-temperature test chamber, and the connection is sealed. The real-time dynamic evaluation device for the performance of the de-icing agent is connected to an external power source or powered by a portable battery.

[0018] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects:

[0019] This device can monitor the effectiveness of de-icing agents in real-time under actual conditions. It can simultaneously collect the amount of de-icing agent applied and its impact on snow or ice samples, overcoming the shortcomings of traditional evaluation methods that cannot reflect the actual performance of de-icing agents under different environmental conditions in real time. Especially in complex and changeable road environments, it can accurately capture the impact of temperature factors on the effectiveness of de-icing agents.

[0020] This invention evaluates the performance of de-icing agents through comprehensive analysis of real-time monitoring data, providing a basis for scientifically guiding the rational use of de-icing agents. It helps optimize the formulation and application strategies of de-icing agents, effectively assisting relevant departments in rationally selecting the type and amount of de-icing agents according to specific usage conditions. While improving the de-icing rate, it reduces unnecessary use of de-icing agents, thereby reducing the cost of using de-icing agents, improving road maintenance efficiency, and reducing the incidence of traffic accidents.

[0021] This invention evaluates the performance of de-icing agents, selects suitable de-icing agents for local conditions, and promotes the scientific use of de-icing agents. This effectively reduces the amount of de-icing agents used, thereby mitigating their impact on the environment and road surfaces, lowering pollution costs, and is of great significance for environmental protection and the long-term maintenance of road facilities.

Detailed Implementation

[0030] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. The embodiments described below do not represent all embodiments consistent with this invention. Rather, they are merely examples consistent with some aspects of this invention as detailed in the appended claims.

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] Example 1

[0033] See Figure 1-5 As shown, this embodiment provides a real-time dynamic evaluation device for the performance of de-icing agents, including a low-temperature test chamber 1, a main control computer 4 located on one side of the low-temperature test chamber 1, and a vacuum pump 9 located on the other side for drawing a vacuum inside the low-temperature test chamber 1; a transparent platform 5 for placing snow or ice samples is provided on one side of the low-temperature test chamber 1, and a photographing device 6 for photographing the snow or ice samples and de-icing agents inside the transparent platform 5 is provided on the other side; a de-icing agent spraying device 8 for dripping de-icing agents is fixedly installed on the top of the low-temperature test chamber 1, above the transparent platform 5; the photographing device 6, the de-icing agent spraying device 8, and the vacuum pump 9 are all electrically connected to the main control computer 4.

[0034] Specifically, the transparent stage 5 has multiple rows and columns of blind holes of the same depth arranged vertically. Preferably, the transparent stage 5 has three rows and four columns of blind holes, with each row having the same diameter and each column having a diameter that increases from small to large. The smaller diameter blind holes are located closer to the imaging device 6, and each row of blind holes is perpendicular to the imaging direction of the imaging device 6. See [reference needed]. Figure 4 and 5 As shown.

[0035] It should be noted that only the same row of blind holes can be used in each experiment, because if two rows of blind holes are used at the same time, the imaging device 6 will capture two overlapping images, which will lead to inaccurate test data.

[0036] Specifically, each of the blind holes is provided with a test tube that matches its size and is used to hold snow or ice samples.

[0037] Specifically, the de-icing agent spraying device 8 includes de-icing agent spraying components adapted to the number of blind holes in each row. Each de-icing agent spraying component includes a de-icing agent solution storage tank 81, a high-pressure pump 82, a delivery pipe 83, and a nozzle 85. The de-icing agent solution storage tank 81 is connected to the nozzle 85 through the high-pressure pump 82 and the delivery pipe 83. Each delivery pipe 83 and nozzle 85 are fixed by a nozzle fixing plate 84. The de-icing agent solution storage tank 81 and the nozzle fixing plate 84 are both fixed to the inner top of the low-temperature test chamber 1. The high-pressure pump 82 is electrically connected to the main control computer 4. See [link to relevant documentation]. Figure 2 and 3 As shown.

[0038] It should be noted that the transparent stage 5 can be moved within the low-temperature test chamber 1 so that the blind holes and nozzles 85 are positioned correspondingly, thereby allowing the de-icing agent to be accurately added into the corresponding blind holes.

[0039] Specifically, the transparent stage 5 is made of epoxy resin or acrylic, and the outer periphery of the transparent stage 5 is engraved with scale lines 51 to facilitate reading the liquid level in the blind hole.

[0040] Specifically, the vacuum pump 9 is connected to the low-temperature test chamber 1 through the pump pipe 10 and is fixed outside the low-temperature test chamber 1 through the pump support frame 11.

[0041] Specifically, the shooting device 6 includes a high-precision camera that collects video information and thermal imaging temperature information, and the shooting device 6 is set inside the low-temperature test chamber 1 by a bracket 7.

[0042] Specifically, the low-temperature test chamber 1 is also provided with an observation window 3, which is detachably and sealed to the low-temperature test chamber 1 through a sealing frame 2.

[0043] Specifically, the sealing frame 2 is connected to the low-temperature test chamber 1 by bolts.

[0044] Specifically, a sealing silicone sealant is provided between the sealing frame 2 and the low-temperature test chamber 1.

[0045] It should be noted that the low temperature test chamber 1 is a refrigeration chamber with a temperature range of 0 to -35℃, which can be adjusted in increments of 0.5℃. The main control computer 4 is electrically connected to the imaging device 6, vacuum pump 9, and high pressure pump 82 via cables. When the cables pass through the low temperature test chamber 1, they are all sealed to the low temperature test chamber 1. The pump pipe 10 is connected to the low temperature test chamber 1, and the connection is sealed.

[0046] This embodiment also provides a method for using the real-time dynamic evaluation device for the performance of de-icing agents, as detailed below:

[0047] First, put the snow or ice sample into four test tubes of the same size, and then put the test tubes into the blind hole of the transparent stage 5 that matches the size of the test tubes. Then, inject the de-icing agent to be tested into the de-icing agent solution storage tank 81. Then, install the transparent stage 5 and the de-icing agent spraying device 8 into the low temperature test chamber 1. When placing the transparent stage 5, the blind hole into which the test tube is placed should be aligned with the nozzle 85. Then, use the sealing frame 2 to seal the observation window 3 to the low temperature test chamber 1.

[0048] Next, the temperature inside the low-temperature test chamber 1 is adjusted to the actual temperature of the snow or ice sampling site, and the vacuum pump 9 is turned on to evacuate the low-temperature test chamber 1 to a vacuum degree of 5-10 kPa. At the same time, the shooting device 6 is turned on, and the main control computer 4 receives the video information and thermal imaging temperature information captured by the shooting device 6 inside the transparent platform 5 in real time. The melting process of the snow or ice sample inside the transparent platform 5 is reflected in real time on the main control computer 4, monitoring the change process of the snow or ice sample, measuring the change in the thickness of the snow or ice sample in real time, and measuring the temperature change during the melting process of the snow or ice sample. After comparing the data of different de-icing agents, a suitable de-icing agent is selected to melt the ice and snow on the local road surface.

[0049] It should be noted that before the experiment, the transparent stage 5, test tubes, and other equipment should be placed in the experimental temperature for 10 hours to reduce the influence of equipment temperature on the experiment.

[0050] Example 2

[0051] The difference between this embodiment and embodiment 1 is that the transparent stage 5 can also be observed with the naked eye through the observation window 3. Simply place a row of blind holes of the same size on the transparent stage 5 facing the observation window 3, place the test tube containing snow or ice sample in the row of blind holes closest to the observation window 3, and manually add the de-icing agent to quickly observe the change process of the de-icing agent.

[0052] The above description is merely a specific embodiment of this utility model, enabling those skilled in the art to understand or implement it. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this utility model.

[0053] It should be understood that this utility model is not limited to the content already described above, and various modifications and changes can be made without departing from its scope. The scope of this utility model is limited only by the appended claims.
