[0050] Technologies, methods, and apparatus known to persons of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and apparatus should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values. Example

[0051] Combine Figure 1 and Figure 6 As shown, this embodiment provides a movable explosion sensor device, which includes a high-pressure pump 1, an electric control box 2, a remote control device 3, a sensor cavity 4, a movable baffle assembly 5, a water tank 6 and a main frame 7.

[0052] The high-pressure pump 1, the body-sensing cavity 4 and the water tank 6 are all placed on the main frame 7. The body-sensing cavity 4 is located on the upper side of the water tank 6. The body-sensing cavity 4 is connected to the water tank 6 through the drainage bucket 8. The movable baffle assembly 5 is placed inside the body-sensing cavity 4.

[0053] The high-pressure pump 1 is sealedly connected to one end of a pump inlet pipe 11 , and the other end of the pump inlet pipe 11 is sealedly connected to the water tank 6 .

[0054] The high-pressure pump 1 is sealedly connected to one end of a pump outlet pipe 12 , and the other end of the pump outlet pipe 12 is sealedly connected to the body sensing cavity 4 .

[0055] One end of the pump outlet pipe 12 extending into the body sensing cavity 4 is sealed and connected to a water spray device 9, which can spray a water column; the nozzle 91 on the water spray device 9 matches the movable baffle assembly 5, and a solenoid valve 13 is provided on the pump outlet pipe 12.

[0056] In this embodiment, when performing an explosion sensation demonstration, the high-pressure pump 1 pumps water out of the water tank 6 through the pump inlet pipe 11, and then transports the water to the water spray device 9 through the pump outlet pipe 12. The nozzle 91 on the water spray device 9 sprays high-pressure water flow to impact the movable baffle assembly 5, thereby simulating the impact effect of the explosion. Using the impact force of water to simulate the explosion test is safer, more reliable, and more intuitive, which can improve people's safety awareness.

[0057] Combine Figure 1 As shown, the electric control box 2 is arranged on the outer wall of the body sensing cavity 4, and a frequency conversion controller 21 for adjusting the high-pressure pump power is provided in the electric control box 2. A control button 22 for controlling the high-pressure pump power is provided in the electric control box 2, and the remote control device 3 is placed in the electric control box 2.

[0058] As one of the preferred implementations in this embodiment, the frequency conversion controller 21 can be used to change the frequency of the motor of the high-pressure pump 1, and the outlet pressure of the high-pressure pump 1 at different speeds is different; the control button 22 is used to adjust the water outlet pressure of the nozzle 91, which is convenient for controlling the water pressure so as to demonstrate the explosion scene.

[0059] As an example and not a limitation, the user can also control the water pressure through the remote control device 3 to realize the remote control function. The maximum remote control distance can reach 100 meters, which is convenient for people to operate from a farther position during the demonstration.

[0060] Combine Figure 1 and Figure 7 As shown, the movable baffle assembly 5 includes: a baffle 11 , a pulley 512 , a tension spring 513 and a guide rail 514 .

[0061] The pulleys 512 are arranged at the four corners of the baffle 11, and the guide rails 514 are arranged on the inner wall of the body sensing cavity 4. The pulleys 512 are respectively placed in the guide rails 514, and one end of the guide rail 514 is fixedly connected to the pulley 512 through a tension spring 513, and the tension spring 513 is located at the same end of the guide rail 514.

[0062] As one of the preferred implementations in this embodiment, the baffle 511 is a 3 mm thick acrylic plate, the guide rail 514 is arranged on the two upper and lower opposite inner walls of the somatosensory cavity 4, and the pulleys 512 are respectively placed in multiple guide rails 514, so that the moving trajectory of the pulley 512 is fixed, that is, the moving trajectory of the baffle 511 is fixed; four identical tension springs 513 are used to fix the pulley 512 so that it moves the same displacement under the push of the same magnitude of force. When the pushing force is removed, the pulley 512 in the guide rail 514, that is, the baffle 511, can be restrained by the tension spring 513 to return to the position before the push.

[0063] Preferably, the nozzle 91 can spray water and move the baffle 511, and the distance from the nozzle 91 to the center of the baffle 511 is the same.

[0064] In this embodiment, four nozzles 91 are provided, and the diameter of the nozzles 91 is less than 3 mm; the direction of the water flow sprayed by the nozzles 91 should be perpendicular to the baffle 511 to ensure that the force on the baffle 511 is uniform. The four nozzles 91 are placed at the four corners of the baffle 511, and the four nozzles 91 are at the same position relative to the center of the baffle 511. In this way, the force of the water flow impacting the baffle 511 can be uniform, avoiding the baffle 511 from tilting.

[0065] Combine Figure 2 As shown, a pressure pipe 14 is further provided on the pump outlet pipe 12 , and a pressure sensor 15 is provided on the pressure pipe 14 . The pressure sensor 15 is electrically connected to the electric control box 2 , and the pressure pipe 14 is located near the water outlet of the high-pressure pump 1 .

[0066] In this embodiment, the pressure pipe 14 is located near the pump outlet to monitor the water pressure at the pump outlet. The outlet pressure of the high-pressure pump 1 can be viewed in real time through the pressure sensor 15, which is used to control the outlet pressure of the high-pressure pump 1 and realize pressure grading. The signal of the pressure sensor 15 is fed back to the control system in the electric control box 2, so that the electric control box 2 can control the water pressure.

[0067] It's worth noting that the solenoid valve 13 is equipped with a pressure threshold to control its opening and closing. The solenoid valve 13 is linked to signals from the high-pressure pump 1 and the pressure sensor 15. After the high-pressure pump 1 is activated, the pressure sensor 15 measures the water pressure in the pressure pipe 14. When the water pressure reaches the pressure threshold of the solenoid valve 13, the solenoid valve 13 opens, ensuring that the sprinkler 91 can always provide a high water pressure. For demonstration purposes, the opening and closing of the solenoid valve 13 are instantaneous, with each opening and closing process taking less than one second.

[0068] Combine Figure 3 and Figure 4 As shown, the thickness of the side wall of the somatosensory cavity 4 facing the nozzle 91 is greater than 10 mm, and the upper side wall of the somatosensory cavity 4 has a hole.

[0069] A small hole 81 is provided in the middle of the drainage bucket 8 , and the opening area of ​​the drainage bucket 8 is not less than 1 / 3 of the total area of ​​the bottom plate. A drainage plate 82 is also provided on the drainage bucket 8 .

[0070] The water tank 6 is provided with a drain port 61 at the bottom, and a valve is provided on the drain port 61 .

[0071] The upper opening of the water tank 6 is open, and the opening area on the upper side of the water tank 6 is larger than 3 times the bottom opening area of ​​the drainage bucket 8. The total volume of the water tank 6 is larger than 10 times the total volume of the pressure pipe 15 and the high-pressure pump 1.

[0072] As an example and not a limitation, the body sensing cavity 4 is made of acrylic board, the valve is a manual ball valve 62, the drain port 61 and the manual ball valve 62 can facilitate the replacement of circulating water, and the water tank 6 can be made of PP board.

[0073] Combine Figure 5 As shown, a universal wheel 71 is provided at the bottom of the main frame 7 , and a locking device 72 is provided on the universal wheel 71 . The main frame 7 and the body sensing cavity 4 are connected by a clamping leg 73 .

[0074] In this embodiment, the universal wheel 71 can facilitate the movement of the device, and the locking device 72 can be used to lock the universal wheel 71 to fix the device. The support legs 73 can be removed to facilitate the installation and replacement of the water tank 6.

[0075] Combine Figures 8 to 11 As shown, the water spraying device 9 includes a spherical cavity 92 , and the spray head 91 is arranged on the spherical cavity 92 .

[0076] The movable baffle assembly 5 includes a slide rod 521 fixed to the nozzle 91 of the spherical cavity 92 . An arc plate 522 matching the nozzle 91 is fixedly connected to the slide rod 521 via a spring 523 . The arc plate 522 surrounds the spherical cavity 92 .

[0077] As a preferred implementation method in this embodiment, the water spray device 9 is set to be spherical, and the nozzles 91 are evenly distributed on the spherical cavity 92. The high-pressure water column sprayed by the nozzles 91 impacts the curved plate 522, causing the curved plate 522 to diffuse outward; the entire device can make the simulated explosion more realistic. During the demonstration, the audience can more intuitively observe the effects and hazards of the explosion, thereby improving people's safety awareness.

[0078] Combine Figure 9 As shown, the end of the slide rod 521 away from the spherical cavity 92 is snap-connected with an elastic bag 524, and the side wall of the arc plate 522 away from the spherical cavity 92 is smoothly arranged. When the arc plate 522 is impacted by the water column, it abuts against the elastic bag 524.

[0079] It is worth noting that placing the elastic bag 524 on the slide rod 521 can squeeze the elastic bag 524 when the arc plate 522 spreads outward. By observing the degree to which the elastic bag 524 is squeezed by the arc plate 522, people can more intuitively observe the pressure generated by the explosion.

[0080] Combine Figure 11As shown, the end of the slide rod 521 away from the spherical cavity 92 is snap-connected with an elastic capsule 524, and the side wall of the arc plate 522 away from the spherical cavity 92 is provided with a needle 525 for puncturing the elastic capsule 524. When the arc plate 522 is impacted by the water column, the needle 525 and the elastic capsule 524 are abutted.

[0081] As an example and not a limitation, the elastic bag 524 can be a balloon. By providing a needle 525 on the side wall of the curved plate 522, when the curved plate 522 is impacted by the water flow and diffuses outward, the needle 525 will puncture the balloon, thereby generating an explosion sound, allowing people to experience the explosion scene auditorily, making the device simulation demonstration effect better, and at the same time the entire device is very safe, and no safety accidents will occur during the demonstration.

[0082] Other technical features are described in the previous embodiments and will not be repeated here.
