Description

Technical Field

[0001] This utility model relates to the technical field of equipment related to the operation assessment of self-rescue devices, specifically a monitoring device for the operation assessment of self-rescue devices in gas environments. Background Technology

[0002] A self-rescue device is a portable device that provides respiratory protection to workers in the event of gas explosions, fires, or other disasters in environments such as coal mines and chemical plants. It isolates workers from harmful gases or filters toxic components, ensuring they have access to safe oxygen during escape. The purpose of self-rescue device operation assessments is to verify whether workers can correctly and quickly put on the device in an emergency, ensuring they are familiar with the device's principles and operating procedures. This enables effective protection in real disasters, reducing the risk of injury or death. Furthermore, standardized assessments improve workers' safety skills and strengthen their awareness of safe production.

[0003] A search revealed that Chinese patent application number CN202122735956.4 discloses a simulated coal mine self-rescue device assessment system, which includes a self-rescue device control panel and a simulated self-rescue device. The control panel is equipped with a touch screen all-in-one machine and a dummy model.

[0004] The aforementioned technical solutions and traditional self-rescue device operation assessment equipment all have shortcomings. For example, using open spaces or static models cannot simulate the real underground environment, leading to a disconnect between trainees' operating habits and actual combat needs. In addition, relying solely on theoretical explanations and simple simulation demonstrations lacks effective assessment of trainees' practical operating abilities. When trainees actually encounter a gas accident, they may be unable to use the self-rescue device correctly due to unfamiliarity or non-standard operation, thereby endangering their lives.

[0005] Therefore, we need to propose a gas environment self-rescue device operation assessment and monitoring device. Utility Model Content

[0006] The purpose of this invention is to provide a gas environment self-rescue device operation assessment and monitoring device that is closer to the real underground environment, avoiding the problem of trainees' operating habits being out of touch with actual combat needs caused by traditional open spaces or static models. It allows trainees to conduct operation assessments in a more realistic scenario, improving their ability to cope with actual gas accidents, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A gas environment self-rescue device operation assessment and monitoring device includes:

[0009] abutment;

[0010] An auditing unit is located on one side of the base. The auditing unit includes a chair for the auditor to sit on and a one-way transparent glass, with the chair facing the one-way transparent glass.

[0011] The assessment unit is located on one side of the base. The assessment unit includes a cabin and door panels. Door panels are installed at both ends of the cabin, allowing operators to enter from one end and exit from the other. An opening is made on the side of the cabin closest to the assessment unit, and a one-way transparent glass is installed inside the opening. Operators simulate the operation of self-rescue devices inside the cabin, and assessors assess the operators through the one-way transparent glass.

[0012] Preferably, it also includes a canopy, which is set above the review unit. A support is provided on the base, and the canopy is installed on the upper end of the support to protect the reviewers from rain and snow.

[0013] Preferably, it also includes an audible and visual alarm unit, which is installed inside the cabin. The audible and visual alarm unit includes a speaker and a warning light, and is used to simulate disaster signals inside the mine.

[0014] Preferably, it also includes a start button, which is located inside the cabin. A top plate is fixed inside the cabin by a bracket, and the start button is installed on the top plate. The operator can trigger the assessment timer and audible and visual alarm by pressing the start button.

[0015] Preferably, it also includes a control panel, which is located outside the cabin. The control panel is mounted on the base via a bracket. The control panel is located on one side of the one-way transparent glass. The control panel has an external display screen and control buttons. The control panel has a built-in PLC controller. The display screen shows the assessment time, and the control buttons control the start and stop of the assessment.

[0016] Preferably, it also includes an environmental simulation unit, which is disposed on the top of the cabin. The environmental simulation unit includes two sets of tanks symmetrically installed on both sides of the top of the cabin, and the two sets of tanks are respectively filled with glycerin and bittering agent.

[0017] Both sets of tanks are equipped with a pump on one side. The pump's inlet is connected to the inside of the tank via a pipe, and the pump's outlet is connected to an output pipe that extends to the top of the tank. A nozzle is installed at the end of the output pipe. Glycerin mist and bittering agent solution are sprayed into the tank through the pump to simulate a real gas leak environment from the perspectives of sight, smell, and taste.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. Doors are installed at both ends of the cabin, allowing operators to enter from one end and exit from the other, simulating actual underground entry and exit scenarios. A one-way transparent glass is installed on the side of the cabin near the review unit, allowing reviewers to observe the operator's actions. This relatively enclosed space setting with a certain entry and exit process is closer to the real underground environment, avoiding the problem of trainees' operating habits being out of touch with actual combat needs caused by traditional open spaces or static models. It allows trainees to be assessed in a more realistic scenario, improving their ability to respond to actual gas accidents.

[0020] 2. An environmental simulation unit is set up on the top of the cabin. The liquid in the tank containing glycerin and bittering agent is sprayed into the cabin through the pump to form glycerin mist and bittering agent solution. The real gas leak environment is simulated from the perspectives of sight, smell and taste, which further enhances the realism of the assessment environment. This allows trainees to better adapt to the actual gas leak scenario during the assessment and improve their operational proficiency and standardization. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-3 This utility model provides a technical solution:

[0027] A gas environment self-rescue device operation assessment and monitoring device includes:

[0028] Abutment 1;

[0029] The audit unit is located on one side of the base 1. The audit unit includes a seat 4 for the auditor to sit on and a one-way transparent glass 3. The seat 4 faces the one-way transparent glass 3.

[0030] The auditing unit is located on one side of the base 1, with seat 4 facing the one-way mirror 3. The one-way mirror 3 utilizes the principle of optical reflection to allow auditors to clearly observe the situation inside the cabin from one side, while trainees inside the cabin cannot see outside, thus avoiding interference with trainees' operations.

[0031] The above technical solution provides auditors with a comfortable observation position and enables undisturbed visual auditing of trainees' operation process through one-way transparent glass 3, ensuring the objectivity and fairness of the assessment process and facilitating the detection of non-standard practices in trainees' operations.

[0032] Please see Figure 1-2 :

[0033] The assessment unit is located on one side of the base 1. The assessment unit includes a cabin 2 and a door panel 7. Door panels 7 are installed at both ends of the cabin 2, allowing the operator to enter from one end and exit from the other end. An opening is made on the side of the cabin 2 closest to the audit unit, and a one-way transparent glass 3 is installed inside the opening. The operator performs a simulated operation of the self-rescue device inside the cabin 2, and the auditor audits the operator through the one-way transparent glass 3.

[0034] The cabin 2 is made of sealed welded metal sheets, with door panels 7 installed at both ends to form a closed space. Trainees enter through one door panel 7, complete the operation, and exit through the other end. An opening is made on the side of cabin 2 closest to the audit unit, and a one-way transparent glass 3 is installed to form an observation window.

[0035] The above technical solution simulates the enclosed environment of an underground mine, providing trainees with an assessment environment close to a real-world scenario. The two end doors (7) are designed to simulate escape routes, requiring trainees to complete operations within a confined space, thus enhancing their adaptability in actual disasters. The one-way transparent glass (3) window facilitates observation and evaluation by the assessors.

[0036] For a preferred embodiment, please refer to Figure 1 It also includes a canopy 5, which is set above the audit unit. A support 6 is set on the base 1, and the canopy 5 is installed on the upper end of the support 6 to protect the auditors from rain and snow.

[0037] The canopy 5 is fixed to the base 1 by the bracket 6 and is located above the audit unit. The bracket 6 is made of steel structure, and the canopy 5 is covered with waterproof board, which has the functions of rainproof and sun protection; it provides auditors with protection from rain, snow and sun, ensuring that the assessment work can be carried out smoothly under different weather conditions, and improving the environmental adaptability and ease of use of the device.

[0038] For a preferred embodiment, please refer to Figure 2 It also includes an audible and visual alarm unit, which is installed inside the cabin 2. The audible and visual alarm unit includes a speaker and a warning light 8. The audible and visual alarm unit is used to simulate disaster signals inside the mine.

[0039] The audible and visual alarm unit is installed inside cabin 2. A speaker plays simulated mine disaster sounds (such as gas explosions and equipment alarms), and warning lights 8 emit flashing red or yellow light. It is connected to the start button 9 and the PLC controller via a circuit and is triggered by a timing system during assessment.

[0040] The above technical solutions can simulate the sound and light signals when a disaster occurs inside a mine, creating a tense disaster atmosphere, stimulating trainees with pressure, testing their operational capabilities under emergency conditions, and improving the authenticity and effectiveness of the assessment.

[0041] For a preferred embodiment, please refer to Figure 2 It also includes a start button 9, which is located inside the cabin 2. The cabin 2 has a top plate fixed inside by a bracket 6, and the start button 9 is installed on the top plate. The operator can trigger the assessment timer and sound and light alarm by pressing the start button 9.

[0042] The start button 9 is fixed to the top plate of the bracket 6 inside the cabin 2 and connected to the PLC controller of the control panel 10 via a wire. After the trainee presses the button, an electrical signal is sent to the PLC, triggering the start of the assessment timer and activating the audible and visual alarm unit.

[0043] The above technical solution can be used as a trigger device to start the assessment, simulating an emergency start-up scenario during a disaster, training trainees' emergency response capabilities, and ensuring the accuracy and consistency of the assessment timing.

[0044] For a preferred embodiment, please refer to Figure 1-2 It also includes a control panel 10, which is located outside the cabin 2. The control panel 10 is mounted on the base 1 via a bracket 6.

The control panel 10 has a built-in PLC controller. The display screen shows the assessment time, and the control buttons control the start and stop of the assessment.

[0045] The control panel 10 has a built-in PLC controller, which controls the assessment process through programming. The display screen shows the assessment time in real time, and the control buttons are used to manually start or stop the assessment. The PLC receives the signal from the start button 9, controls the audible and visual alarms and the timer, and transmits the data to the display screen.

[0046] The above technical solutions enable automated control and data display of the assessment process. Auditors can set assessment parameters and view timing information through the control panel 10, ensuring that the assessment process is standardized, the data is traceable, and the standardization of the assessment is improved.

[0047] For a preferred embodiment, please refer to Figure 1-3 It also includes an environmental simulation unit, which is located on the top of the chamber 2. The environmental simulation unit includes two sets of tanks 11 symmetrically installed on both sides of the top of the chamber 2. The two sets of tanks 11 are filled with glycerin and bittering agent respectively. A pump body 12 is installed on one side of each of the two sets of tanks 11. The inlet end of the pump body 12 is connected to the inside of the tank 11 through a pipe. The outlet end of the pump body 12 is connected to an output pipe, which extends to the top of the chamber 2. A nozzle 13 is installed at the end of the output end. Glycerin mist and bittering agent solution are sprayed into the chamber 2 through the pump body 12 to simulate the real gas leak environment from the aspects of vision, smell and taste.

[0048] The two tanks 11 of the environmental simulation unit are respectively filled with glycerin and bittering agent solution. The pump 12 draws the liquid from the tanks 11 through pipes and sprays it into the interior of the chamber 2 through the nozzle 13 via the output pipe. The glycerin mist forms a visual mask, simulating the smoke environment during a gas leak; the bittering agent solution volatilizes and stimulates the sense of smell and taste, simulating a real gas leak scenario from multiple senses.

[0049] Through the above technical solutions, a near-realistic gas leak environment is constructed from three dimensions: sight, smell, and taste. This enhances the immersiveness of the assessment scenario, allowing trainees to conduct operational training under multi-sensory stimulation, improving their operational proficiency and adaptability in actual disasters, and ensuring that the assessment results are highly aligned with practical needs.

[0050] The tank 11 has a filling port on its top.

[0051] In this embodiment, the specific design can be as follows:

[0052] The glycerol mist released by nozzle 13 has a particle size of 1-5μm, and the bittering agent is a benzyl denatum solution (concentration 0.001%-0.005%). After being pressurized by pump body 12, the glycerol is atomized through nozzle 13 and diffuses in the cabin to reduce visibility, simulating the smoke environment caused by gas leaks or fires. The bittering agent solution evaporates after spraying, producing an irritating odor and taste experience, simulating the sensory characteristics of harmful gases such as gas. The start and stop of pump body 12 and the flow rate are adjusted by PLC controller according to the requirements of the assessment scenario to realize the simulation of different concentrations of environment.

[0053] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
