Description

Technical Field

[0001] This utility model relates to the field of heatstroke prevention technology, specifically a temperature monitoring equipment testing device. Background Technology

[0002] Temperature monitoring devices are a general term for a type of equipment that collects temperature data of a target object in real time through sensors and transmits the data to a terminal for analysis, storage, and early warning. The core function is to realize real-time monitoring of temperature changes and abnormal alerts to avoid safety risks such as heatstroke caused by excessive temperature.

[0003] When testing temperature monitoring devices, they are often conducted in static environments, and the scene reproduction is far from matching the actual usage requirements. The movement of people in real-world scenarios makes it impossible to verify the device's dynamic tracking capabilities and response speed. Furthermore, the sweating state of people in high-temperature environments may cause the temperature measurement signal to be reflected or scattered, resulting in deviations between the readings and the actual data. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a temperature monitoring equipment testing device, including a sealed chamber, a temperature monitor and a human body model, wherein a detection component is provided inside the sealed chamber and an environmental component is provided inside the sealed chamber;

[0006] The detection assembly includes a reciprocating screw that is rotatably embedded inside the sealed chamber, and the reciprocating screw is connected to a threaded block through a ball nut pair. The human model is fixedly connected to the top of the outer surface of the threaded block, the temperature monitor is fixedly connected to one side of the inner wall of the sealed chamber, and push block shafts are fixedly connected to both sides of the outer surface of the threaded block.

[0007] The environmental component includes two sets of liquid cylinders, each with a liquid delivery pipe inside. The liquid delivery pipe has an atomizing nozzle inside. A dust collection box is fixedly connected to the bottom of the inner wall of the sealed chamber. An air cylinder is fixedly connected to the bottom of the inner wall of the sealed chamber, and an air outlet pipe is installed inside the air cylinder. The end of the air outlet pipe away from the air cylinder is located inside the dust collection box.

[0008] Preferably, a liquid tank is fixedly connected to the bottom of the inner wall of the sealed chamber, and a liquid replenishment pipe is provided inside the liquid tank. Both sets of liquid cylinders are provided with liquid inlet pipes, and the ends of the two sets of liquid inlet pipes away from the liquid cylinders are located inside the liquid tank. A first one-way valve is provided inside the two sets of liquid inlet pipes.

[0009] Preferably, the interior of both sets of liquid cylinders is horizontally slidably embedded with a first sliding rod, and one side of the outer surface of each set of first sliding rods is fixedly connected with a first piston, and the interior of each set of first pistons is horizontally slidably embedded inside the liquid cylinder.

[0010] Preferably, a first baffle is fixedly connected to the outer surface of both sets of the first slide rods, and a first spring is wound around the outer surface of both sets of the first slide rods.

[0011] Preferably, the air cylinder has a second sliding rod slidably embedded in the interior in a horizontal direction, and a second piston is fixedly connected to one side of the outer surface of the second sliding rod. The interiors of the two sets of second pistons are slidably embedded in the air cylinder in a horizontal direction, and a second one-way valve is provided inside the air cylinder.

[0012] Preferably, a second baffle is fixedly connected to the outer surface of each of the second slide rods, and a second spring is wound around the outer surface of each of the two sets of second slide rods.

[0013] Preferably, a drive motor is fixedly connected to one side of the outer surface of the sealed chamber, and the output shaft of the drive motor is fixedly connected to a reciprocating lead screw. A limit rod is fixedly connected to one side of the inner wall of the sealed chamber, and the threaded block is slidably sleeved on the outer surface of the limit rod in a horizontal direction.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0015] First, this invention tests the temperature monitor in a sealed chamber. A human model is heated, and then a drive motor is activated. The output shaft of the drive motor moves a reciprocating screw, which in turn moves a threaded block, which in turn moves the human model. During this movement, the temperature monitor continuously monitors the human model. This technical solution, combining a material similar to human skin with a built-in heating component, achieves uniform and stable temperature output. It also simulates the stable walking rhythm of a person in a confined space, accurately determining the initial target temperature reading and maintaining a stable reading. This avoids misjudgments due to irregular movement. Furthermore, it assesses whether the temperature monitor can quickly follow changes in the target's position when the target moves away, preventing delays in response where the target has moved out of the detection range before an effective temperature reading is output. This simulates a real-world scenario where people are not stationary and the temperature monitor must continuously track the moving target to detect abnormal body temperatures promptly.

[0016] Secondly, in this invention, workers add water to the liquid tank and dust to the dust collection box in advance via a replenishment pipe. When the threaded block moves, it drives the pusher shaft to move, pushing the first sliding rod. The first sliding rod and the first piston slide inside the liquid cylinder, thereby discharging the water inside the liquid tank through the liquid delivery pipe and the atomizing nozzle. The water mist is then sprayed onto the surface of the human model through the atomizing nozzle, simulating human sweating. When the human model moves to the second sliding rod, the pusher shaft further pushes the second sliding rod and the second piston to slide inside the air cylinder. The second piston compresses the gas inside the air cylinder, thus discharging the gas inside the air cylinder through the air outlet pipe into the dust collection box. The gas blows the dust inside the dust collection box, causing it to float. Through the above technical solution, the simultaneous spraying of water mist simulates human sweating, effectively replicating the effect of sweat on the body surface's heat radiation. When the human body sweats, a thin film of water forms on the skin due to evaporation and heat dissipation. This film may alter the reflectivity of the infrared signal from the temperature monitor, leading to a lower reading. Simultaneous water mist spraying simulates the dynamic sweating process, testing whether the temperature monitor can counteract the interference of sweat and maintain accurate readings. At the same time, blowing away dust simulates a localized pollution scenario in a confined space, such as a workshop area with high dust concentration. This verifies the impact of dust particles on the temperature monitor's signal obstruction and scattering, avoiding target loss or significant reading deviations due to dust in actual use. By simulating sweat and dust, the test closely approximates real-world usage needs, improving its practicality. Furthermore, after water mist spraying, the surface of the human model becomes wet, making it easier for dust particles to adhere and form a dust layer, further enhancing the obstruction of the temperature signal. The interference from the movement of the human model, combined with the interference from dust and sweat, amplifies the overall interference effect, improving the comprehensiveness of the test.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

The human model 9 is fixedly connected to the top of the outer surface of the threaded block 202. The temperature monitor 8 is fixedly connected to one side of the inner wall of the sealed chamber 1. Push block shafts 203 are fixedly connected to both sides of the outer surface of the threaded block 202.

[0026] The environmental component includes two sets of liquid cylinders 3, and each set of liquid cylinders 3 is equipped with a liquid delivery pipe 305. The liquid delivery pipe 305 is equipped with an atomizing nozzle 306. A dust collection box 6 is fixedly connected to the bottom of the inner wall of the sealed chamber 1. An air cylinder 5 is fixedly connected to the bottom of the inner wall of the sealed chamber 1. An air outlet pipe 506 is installed inside the air cylinder 5. The end of the air outlet pipe 506 away from the air cylinder 5 is located inside the dust collection box 6.

[0027] Through the above technical solution, the temperature monitor 8 is tested in a sealed chamber 1. The human model 9 is heated, and then the drive motor 7 is turned on. The output shaft of the drive motor 7 drives the reciprocating screw 2 to move. The rotation of the reciprocating screw 2 drives the threaded block 202 to move. The movement of the threaded block 202 drives the human model 9 to move. During the movement of the human model 9, the temperature monitor 8 continuously monitors the human model 9. Through the above technical solution, the material of the existing human model 9 is close to human skin. The combination of the built-in heating component can achieve uniform and stable temperature output. At the same time, it simulates the stable walking rhythm of a person in a closed space, so as to accurately determine the specific distance at which the temperature monitor 8 first identifies the target temperature and maintains a stable reading. It avoids misjudgment of the detection distance due to irregular movement. When the target moves close to the temperature monitor 8, it can quickly follow the change in the target position to avoid the problem that the target has moved out of the detection range before the effective temperature is output due to response lag. It simulates that in the actual scenario, the person will not be stationary and wait to be measured. The temperature monitor 8 needs to continuously track the moving target to detect abnormal body temperature in time.

[0028] Through the above technical solution, staff add water to the liquid tank 4 and dust to the dust collection box 6 in advance through the replenishment pipe 401. When the threaded block 202 moves, it drives the pusher shaft 203 to move. During the movement of the threaded block 202, it pushes the first slide rod 301 to move. The first slide rod 301 and the first piston 302 slide inside the liquid cylinder 3, thereby discharging the water inside the liquid tank 4 through the liquid delivery pipe 305 and the atomizing nozzle 306. The atomizing nozzle 306 sprays water mist onto the surface of the human model 9, simulating human sweating. When the human model 9 moves to the second slide rod 501, the pusher shaft 203 pushes the second slide rod 501 and the second piston 502 to slide inside the air cylinder 5. The second piston 502 compresses the gas inside the air cylinder 5, thereby discharging the gas inside the air cylinder 5 into the dust collection box 6 through the air outlet pipe 506. The gas blows the dust inside the dust collection box 6 to float. Through the above technical solution, the same The water mist spray simulates human sweating, replicating the effect of sweat on the body's heat radiation. After sweating, the body surface forms a thin water film due to evaporation and heat dissipation, which may change the reflectivity of the infrared signal of the temperature monitor 8, leading to a lower reading. The simultaneous water mist spraying simulates the dynamic sweating process, testing whether the temperature monitor 8 can counteract the interference of sweat and maintain accurate readings. At the same time, blowing dust simulates a local pollution scenario in a confined space, such as a high dust concentration in a certain area of ​​a workshop, verifying the effect of dust particles on the obstruction and scattering of the temperature measurement signal of the temperature monitor 8. This avoids the loss of the target or significant deviation in readings due to dust in actual use. By simulating sweat and dust, the test closely matches actual usage needs, improving its practicality. After the water mist spraying, the surface of the human model 9 becomes wet, and dust particles are more likely to adhere to the surface, forming a dust layer, further enhancing the obstruction of the temperature measurement signal. The interference from the movement of the human model 9 is superimposed with the interference from dust and sweat, thereby amplifying the interference effect and improving the comprehensiveness of the test.

The movement of the threaded block 202 drives the human model 9 to move. During the movement of the human model 9, the temperature monitor 8 continuously monitors the human model 9. Through the above technical solution, the material of the existing human model 9 is close to human skin.

When the threaded block 202 moves, it drives the pusher shaft 203 to move, pushing the first slide rod 301. The first slide rod 301 and the first piston 302 slide inside the liquid cylinder 3, thereby discharging the water in the liquid tank 4 through the liquid delivery pipe 305 and the atomizing nozzle 306. The water mist is then sprayed onto the surface of the human model 9 through the atomizing nozzle 306, simulating human sweating. When the human model 9 moves to the second slide rod 501, the pusher shaft 203 further pushes the second slide rod 501 and the second piston 502 to slide inside the air cylinder 5. The second piston 502 compresses the gas inside the air cylinder 5, thereby discharging the gas inside the air cylinder 5 into the dust collection box 6 through the air outlet pipe 506. The gas blows the dust inside the dust collection box 6, causing it to float. Through the above technical solution, water is sprayed simultaneously. The mist simulates human sweating, replicating the effect of sweat on the body's heat radiation. After sweating, the body surface forms a thin water film due to evaporation and heat dissipation, which may change the reflectivity of the infrared signal of the temperature monitor 8, leading to a lower reading. The simultaneous spraying of water mist simulates the dynamic sweating process, testing whether the temperature monitor 8 can counteract the interference of sweat and maintain accurate readings.
