Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tunnel evaluation, in particular to a tunnel safety evaluation auxiliary device and an evaluation method. BACKGROUND

[0002] Tunnel design safety evaluation is a process for evaluating the safety of tunnel design; it evaluates the potential risks related to the design, such as structural integrity, light environment in the tunnel, induced indication safety, wall decoration, fire safety, ventilation and emergency evacuation.

[0003] When the tunnel design is basically completed, it needs to be evaluated to eliminate hidden dangers and optimize the design scheme. When evaluating, it needs to rely on the experience of experts. In order to consider the safety and reliability of the evaluation, when evaluating, a tunnel safety evaluation auxiliary device (a virtual reality operation device module) is used to simulate the designed tunnel site environment and display it to the test personnel to realize a more intuitive evaluation. The existing tunnel safety evaluation auxiliary device, when in use, is limited by its own structure and can only simulate the state of a single vehicle driving in the tunnel, and the function is relatively single. In order to ensure the reliability of the evaluation results, multiple people need to evaluate the same tunnel when simulating the test. After multiple people use the same tunnel safety evaluation auxiliary device, the tunnel safety evaluation auxiliary device is easily contaminated by body fluids (sweat) and the like. The contaminated tunnel safety evaluation auxiliary device is inconvenient to clean due to the limitation of its own structure. The tunnel safety evaluation auxiliary device is a closed cabin to isolate external interference, and if not cleaned in time, it is easy to cause bacterial growth and cross contamination. SUMMARY

[0079] Embodiment two

[0080] Considering that the tunnel safety evaluation auxiliary device is a closed cabin to isolate external interference, the internal gas circulation is poor, and in consideration of comfort, the simulation cabin 100 is provided with an air conditioning system 120, which is used for ventilation.

[0081] Preferably, the air conditioning system 120 also has the function of heating and refrigerating the gas in the simulation cabin 100, so that the simulation cabin 100 can simulate different temperatures in different seasons during evaluation.

[0082] In actual evaluation, the evaluator in the simulation warehouse 100 will secrete more sweat due to the temperature influence simulated by the air conditioning system 120 and nervousness, etc. If the evaluator directly walks out of the simulation warehouse 100 after the evaluation ends, it is easy to get sick due to the temperature difference and the sweat on the body not being dry. If the air conditioning system 120 simply adjusts the temperature to assist the evaluator in drying the sweat, the time required is too long. If a fan is directly used to blow air on the human body, it is not only easy to cause the evaluator to have a headache, but also difficult to quickly dry the sweat in some positions. In view of the above problems, the embodiment of the application optimizes the coating film assembly 500 on the basis of the above embodiment, specifically:

[0083] The coating film 520 is composed of a double-layer film, including an outer film 521 and an inner film 522, both of which are made of elastic rubber. The outer film 521 is densely covered with air outlet holes 523, which are through holes. The outer film 521 and the inner film 522 are densely covered with multiple elastic soft strips 524, and the distance between the elastic soft strips 524 is greater than 2 cm. The elastic soft strip 524 is a strip-shaped soft capsule or a rubber soft strip. The elastic soft strip 524 is fixed on the inner film 522. The pump assembly 530 is also provided with a valve body 550, which is a multi-way valve. The pump assembly 530 delivers gas to the space formed by the coating film 520 and the bearing plate 210 and between the two film bodies of the coating film 520 through the valve body 550. The gas delivered between the two film bodies of the coating film 520 is output from the air outlet hole 523 to assist the evaluator in sweating.

[0084] Preferably, the elastic soft strip 524 is densely covered with air permeable holes 525, which are through holes with a distance of 2 to 5 cm between each other, for facilitating the circulation of gas in the space between the outer film 521 and the inner film 522.

[0085] Preferably, the gas output by the pump assembly 530 first passes through the air temperature adjusting assembly 540 before entering the space between the outer film 521 and the inner film 522. The air temperature adjusting assembly 540 is used to adjust the temperature of the gas, preferably a combination of electric heating wires and semiconductor refrigerating sheets. In actual use, the air outlet hole 523 outputs gas with a temperature greater than 15 degrees to assist the evaluator in sweating.

[0086] Preferably, the elastic strip 524 is a long, narrow elastic bladder filled with paraffin wax. In actual use, the expansion of the covering membrane 520 (the covering membrane 520 expands more easily after the paraffin wax melts into liquid) and the shaping of the elastic strip 524 can be assisted by controlling the temperature of the gas entering the space between the outer membrane 521 and the inner membrane 522. (After the paraffin wax liquefies, the elastic strip 524 will gradually shape its cross-section into an approximately circular shape under its own elastic force. At this time, the paraffin wax is cooled to solidify it. After the paraffin wax is solidified, the elastic strip 524's resistance to deformation is enhanced, which can better ensure airflow.)

[0087] Preferably, to further ensure unobstructed airflow within the space between the outer membrane 521 and the inner membrane 522, the inner membrane 522 is densely covered with plugging blocks 526. Each plugging block 526 is a cylindrical rubber block with an inscribed circle diameter larger than the diameter of the vent hole 523. The plugging blocks 526 are located between the outer membrane 521 and the inner membrane 522 and between the elastic strips 524. The elastic strips 524 are also fixed to the outer membrane 521, and the vent holes 523 are also located between the elastic strips 524. Each plugging block 526 corresponds one-to-one with a vent hole 523. When the outer membrane 521 is compressed, the vent holes 523 at the compressed location are blocked by the plugging blocks 526, at which point the plugging blocks 526 provide support. When cleaning and disinfection are required, the elastic strips 524 are softened, causing the plugging blocks 526 to seal the vent holes 523.

[0088] Preferably, the plugging block 526 is provided with one or more through holes.

[0089] To further improve the practicality of this application and increase the sweat drying speed, preferably, a reversing plate 527 is provided between the outer membrane 521 and the inner membrane 522. The reversing plate 527 is fixed on the inner membrane 522 and corresponds one-to-one with the air outlet 523. The reversing plate 527 is a flexible plate with an angle of 60 to 90 degrees between its height direction and the inner membrane 522, and its length direction is the same as the width direction of the elastic soft strip 524. The reversing plate 527 is located between the elastic soft strips 524. In actual use, by changing the air output per unit time of the pumping assembly 530, the angle between the reversing plate 527 and the inner membrane 522 can be changed, thereby changing the direction of the airflow blown out from the air outlet 523, thus accelerating sweat drying and improving comfort.

[0090] Furthermore, the reversing plate 527 includes an elastic base plate 528 and a swing plate 529; the elastic base plate 528 is generally U-shaped with a through hole in the center and is made of rubber; the swing plate 529 is located on top of the elastic base plate 528 and is fixed on the elastic base plate 528 or integrally formed with the elastic base plate 528.
