[0025] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.
[0027] Figure 1This is a schematic diagram of the structure of a pneumatic residual pressure safety experience training device provided by an embodiment of the present invention. This embodiment can be applied to the safety training of simulating residual pressure pinching of pneumatic system of mechanical equipment. Figure 1 As shown, the pneumatic residual pressure safety experience training device of the present application includes: a pneumatic component 200, a control module 300 and at least one fixing fixture 100.
[0028] Among them, the fixing fixture 100 can place or fix different types of experience objects. In this embodiment, the types of experience objects include but are not limited to: human body, bionic props and hard props, that is, the experience object can be a human body or other tools that can be used for residual pressure clamping demonstration of pneumatic system. The fixing fixture 100 is used to place or clamp the experience object to ensure that the experience object does not move during the demonstration. Typically, the fixing fixture 100 includes: a clamp-free fixture and a clampable fixture.
[0029] The pneumatic component 200 is provided with a pressure head 210, which is used to drive the pressure head 210 to move in a direction toward or away from the fixing fixture 100, so that the pressure head 210 applies a pressing action to the experience object. The pneumatic component 200 can be understood as a combination of mechanical devices that use compressed air as a power source, which simulates the residual pressure of the pneumatic system of the mechanical equipment by adjusting the gas pressure. When it is necessary to perform a residual pressure pinching demonstration, the pneumatic component 200 drives the pressure head 210 to move in a direction toward the fixing fixture 100, and the pressure head 210 cooperates with the fixing fixture 100 to apply a pressing action to the experience object; when it is not necessary to perform a residual pressure pinching demonstration, the pneumatic component 200 drives the pressure head 210 to move in a direction away from the fixing fixture 100, and stops applying a pressing action to the experience object.
[0030] The control module 300 is connected to the pneumatic component 200, and is used to obtain a custom scene, and control the pneumatic component 200 to output a corresponding simulated residual pressure according to the custom scene to adjust the pressing force applied by the pressure head 210. Among them, the custom scene can be understood as a specific scene for performing a pneumatic residual pressure pinch injury demonstration. In this embodiment, a custom scene can be set through a human-computer interaction module (such as a display screen or an external tool), and in different custom scenes, the type of experience object, the matching fixture, and the simulated residual pressure output by the pneumatic component 200 are differentiated. Configuration.
[0031] Optionally, the custom scene includes but is not limited to: human contact experience scene, bionic prop experience scene and hard prop experience scene. Accordingly, the experience object in the human contact experience scene is the human body, such as the human palm; the experience object in the bionic prop experience scene is a resin prop or a silicone prop, such as a resin palm model or a silicone palm model; the experience object in the hard prop experience scene is a hard prop, such as a bamboo joint or a can or other hard objects.
[0032] Specifically, when performing the residual pressure pinching demonstration, first, the corresponding experience object is placed in the matching fixing fixture 100 according to the custom demonstration scene. For example, in the bionic prop experience scene, a resin palm model or a silicone palm model is placed in the fixing fixture 100. The control module 300 automatically controls the pneumatic component 200 to output the corresponding simulated residual pressure according to the custom scene, and drives the pressure head 210 to move in the direction toward the fixing fixture 100. The pressure head 210 cooperates with the fixing fixture 100 to apply corresponding pressing force to the experience object. It should be noted that in different custom scenes, the experience object is subjected to different pressing forces, demonstrating different residual pressure hazard results. For example, the human body perceives slight pressing without pain or deformation, the bionic prop can be significantly deformed under the action of pressing force without damage, and the hard prop will be broken or severely deformed under the action of pressing force.
[0033] Therefore, the technical solution of the present application, by setting up matching clamps and pressure-adjustable pneumatic components, and adjusting the simulated residual pressure in combination with training scenarios, realizes different forms of pneumatic residual pressure safety training and demonstrations, thereby solving the problem that existing safety somatosensory equipment lacks props to simulate residual pressure pinching scenarios and cannot meet the learning needs of pneumatic clamp residual pressure safety education, thereby improving the professionalism, practicality, teaching effectiveness and learning enthusiasm of trainees in safety training.
[0034] Optionally, the control module 300 is configured to: when the custom scene is a human contact experience scene, set the simulated residual pressure to any value within the first pressure range; when the custom scene is a bionic prop experience scene, set the simulated residual pressure to any value within the second pressure range; when the custom scene is a hard prop experience scene, set the simulated residual pressure to any value within the third pressure range; wherein the upper limit air pressure value of the first pressure range is less than the lower limit air pressure value of the second pressure range; and the upper limit air pressure value of the second pressure range is less than the lower limit air pressure value of the third pressure range.
[0035] Specifically, the specific values of the first pressure interval, the second pressure interval and the third pressure interval can be established through calibration tests. Among them, the first pressure interval satisfies: the human body can sense slight pressure under the action of pressing pressure, and will not produce pain or deformation; the second pressure interval satisfies: the bionic props will be significantly deformed under the action of pressing pressure and will not be damaged; the third pressure interval satisfies: the hard props will be broken or severely deformed under the action of pressing pressure. By matching different residual pressure data with different scenes, different forms of residual pressure injury display can be achieved, thereby improving the professionalism, safety, practicality, teaching effect and learning enthusiasm of trainees in safety training.
[0036] Optionally, the first pressure interval satisfies: greater than 0 and less than 0.08 MPa; the second pressure interval satisfies: greater than or equal to 0.08 MPa and less than or equal to 0.25 MPa; and the third pressure interval satisfies: greater than 0.25 MPa.
[0037] Specifically, when the custom scene is a human contact experience scene, the simulated residual pressure is set to any air pressure value greater than 0 and less than 0.08MPa, and the demonstration fixing fixture 100 (such as a clamp-free fixture) is used to allow the operator to experience the residual pressure hazard with the palm of his hand. When the custom scene is a bionic prop experience scene, the simulated residual pressure is set to any air pressure value greater than or equal to 0.08MPa and less than or equal to 0.25MPa, and the demonstration fixing fixture 100 (such as a clamp-free fixture) is used to allow the operator to demonstrate the residual pressure hazard with a resin palm model or a silicone palm model. When the custom scene is a hard prop experience scene, the simulated residual pressure is set to any air pressure value greater than 0.25MPa, and the demonstration fixing fixture 100 (such as a clampable fixture) is used to allow the operator to use hard objects such as bamboo joints or cans instead of fingers to demonstrate the residual pressure hazard. By setting multiple residual pressure intervals, the force on the human body can be controlled within a safe range, the force on bionic props can be controlled within a recyclable range, and the force on hard props can be controlled within the range of concrete display of hazards. This makes it easier for trainees to intuitively feel the degree of injury under different residual pressures, thereby improving the practicality, safety and economy of the equipment.

[0039] See also Figures 2 to 4As shown, the pneumatic assembly 200 includes: an air source 201, an air filter 202, a pressure regulating valve 203, a pressure relief valve 204, a reversing valve 205 and a cylinder 206, and the pressure head 210 is pushed by the connecting rod of the cylinder 206. The gas enters the pressure regulating valve 203 through the air source 201 and the air filter 202 in sequence; the pressure regulating valve 203 adjusts the intake pressure based on the simulated residual pressure, and transports the pressure-regulated gas to the intake port of the reversing valve 205 through the pressure relief valve 204 and the intake pipeline; the first air outlet of the reversing valve 205 is connected to the first air inlet of the cylinder 206 through the first air outlet pipeline, and the second air outlet of the reversing valve 205 is connected to the second air inlet of the cylinder 206 through the second air outlet pipeline. When the reversing valve 205 is in the first position, the cylinder 206 drives the pressure head 210 to move in the direction toward the fixing fixture; when the reversing valve 205 is in the second position, the cylinder 206 drives the pressure head 210 to move in the direction away from the fixing fixture. In this embodiment, the pressure relief valve 204 is linked with the pneumatic component 200. When the system pressure exceeds the threshold, the pressure relief valve 204 automatically releases the residual pressure to prevent overload damage.
[0040] In this embodiment, the pressure regulating valve 203 is compatible with automatic pressure regulating mode and manual pressure regulating mode.
[0041] In some embodiments, the pressure relief valve 204 is also used to complete the pressure relief in the air circuit before the pneumatic assembly 200 is started and after the training is completed. The control module 300 is also configured to: after the training is completed, instruct the operator to operate the pressure relief valve 204, and when the operator does not operate the pressure relief valve 204 and contacts the fixing fixture or the pressure head, issue a residual pressure warning according to the simulated residual pressure.
[0042] Specifically, after the training demonstration is over, the control module 300 may issue a "demonstration end" warning message to the external device, instructing the operator to operate the pressure relief valve 204. Whether the operator operates the pressure relief valve 204 is determined by detecting the state flag of the pressure relief valve 204. If the operator does not operate the pressure relief valve 204 after the training demonstration is over, and the operator contacts the fixing fixture 100 or the pressure head 210, a residual pressure warning is issued according to the simulated residual pressure at the current moment. If the simulated residual pressure at the current moment is less than the upper limit air pressure value of the first pressure interval (for example, 0.08 MPa), a low risk warning is issued; if the simulated residual pressure at the current moment is greater than the lower limit air pressure value of the second pressure interval (for example, 0.08 MPa) and less than the upper limit air pressure value of the second pressure interval (for example, 0.25 MPa), a medium risk warning is issued; if the simulated residual pressure at the current moment is greater than the upper limit air pressure value of the second pressure interval (for example, 0.25 MPa), a high risk warning is issued. By setting up a graded warning mechanism in the event of operational errors, operators can detect operational errors in a timely manner, thereby improving the safety performance of residual pressure safety experience training.
[0043] See also Figures 2 to 4As shown, the pneumatic assembly 200 further includes a pressure display element 207, which is disposed in the air path between the pressure regulating valve 203 and the pressure relief valve 204 to display the intake pressure. Typically, the pressure display element 207 includes but is not limited to a pressure gauge.
[0044] Specifically, when the simulated residual pressure is automatically set based on a custom scenario, the operator can read the measured air pressure in the air circuit through the pressure display element 207. If there is a deviation between the measured air pressure and the simulated residual pressure, the operator can manually adjust the pressure regulating valve 203 until the measured air pressure is equal to or approximately equal to the simulated residual pressure (for example, the deviation rate is less than 3%). By setting the pressure display element, it is convenient for the operator to read the air pressure data, thereby improving the accuracy and safety of the simulated residual pressure configuration during the demonstration process.
[0045] See also Figure 3 and Figure 4 As shown, the fixing fixture 100 includes: a platform fixture 110 and a groove fixture 120; the platform fixture 110 is used to place the experience object that is not easily displaced; the groove fixture 120 is used to place and fix the experience object that is easily displaced. Typically, the experience object that is not easily displaced includes but is not limited to: human body, resin palm model and silicone palm model. The experience object that is easily displaced includes but is not limited to: bamboo joints or cans.

[0047] See also Figure 5 As shown, the pneumatic residual pressure safety experience training device of the present application also includes: a movable trolley frame 400; the movable trolley frame 400 is used to install the fixing fixture 100 and the pneumatic assembly 200. Specifically, the movable trolley frame 400 can adopt a special trolley with an aluminum alloy frame, which is light and easy to move.
[0048] Figure 6 This is a schematic diagram of another pneumatic residual pressure safety experience training device provided by an embodiment of the present invention. Figure 6 As shown, the pneumatic residual pressure safety experience training device of the present application also includes: a display module 500 and / or a detection module 600, the display module 500 is connected to the control module 300, and is used to display at least one of the following data: a custom scene, an experience object, the type of the fixing fixture, the simulated residual pressure, and the pressing force. Optionally, the display module 500 can be set with at least one of the following: a data display window and an indicator light, the indicator light uses a gradient color bar to display the simulated residual pressure value; the data display window displays at least one of the following data in different areas: a custom scene, an experience object, the type of the fixing fixture, the simulated residual pressure, and the pressing force.
[0049] The detection module 600 is arranged at the contact surface between the pressure head 210 and the experience object, and is used to collect the pressure data and deformation data borne by the experience object, and send the pressure data and deformation data to the control module; the control module 300 is also used to correct the simulated residual pressure according to the pressure data and deformation data, and generate a training report according to the custom scene, experience object, type of fixing fixture and corrected simulated residual pressure.
[0050] Specifically, a strain gauge sensor can be integrated in the pressure head 210 to collect pressure data and deformation data in real time, and the pressure data and deformation data are fed back to the control module 300. When the custom scene is a human contact experience scene, if the human palm is deformed, the simulated residual pressure in the human contact experience scene is lowered; when the custom scene is a bionic prop experience scene, if the deformation of the bionic prop reaches the tolerance value, the simulated residual pressure in the bionic prop experience scene is lowered. By recording different custom scenes, their corresponding experience objects, the type of fixed fixtures and the corrected simulated residual pressure, a training report is generated to achieve standardization of safety training under different residual pressures.
