Description

Technical Field

[0001] The invention belongs to the technical field of gas detection, in particular to a throwable disaster site monitoring device. Background Art

[0002] Micro gas detection equipment refers to gas detection instruments that are small in size, light in weight, easy to carry and install, and are used to monitor the concentration of gases in the air or in a specific environment in real time. These devices are usually used in fields such as environmental monitoring. Micro gas detection equipment can detect a variety of gases, such as oxygen, carbon dioxide, carbon monoxide, hydrogen sulfide and volatile organic compounds.

[0003] When performing gas detection in confined spaces and other areas, miniature gas detection equipment is often used, such as the patent with application number 202221044116.1, which uses miniaturized miniature gas detection equipment to detect confined spaces or areas.

[0004] When using the micro gas detection equipment, the staff is required to throw the micro gas detection equipment into the room or area to be detected (the area refers to the natural disaster site, which includes meteorological disasters such as forest and grassland fires, sandstorms, earthquake disasters, and geological disasters such as collapse). Since the disaster site is full of gas (for example, there will be smoke during a fire), it is difficult to detect the internal structure of the area, resulting in the blindly thrown micro gas detection equipment being easily hit by objects such as rocks and trees and rebounding out of the area to be detected; at the same time, the thrown micro gas detection equipment is affected by the force, and it is difficult to stay in the preset range after being thrown. As a result, it is difficult for the micro gas detection equipment to accurately and efficiently detect and analyze the gas in the area to be detected.

[0018] 1. The present invention discloses a throwable disaster monitoring device for on-site use. When the area to be detected is full of harmful gases and needs to be monitored, the monitoring device housing is thrown into the area to be detected. Since the monitoring device housing is equipped with a controller such as a Bluetooth module, the monitoring device housing and external devices can be networked and used, and the gas data subsequently monitored by the monitoring device housing is transmitted to the external device, thereby facilitating the staff to observe and analyze the gas in the area to be detected. The positioning mechanism designed can realize that when the monitoring device housing is thrown into the area to be detected, the glue inside is squeezed out quickly by the fixed frame, slide bar, sealing plate and spring, and the bottom frame at the bottom of the monitoring device housing is in contact with the ground in combination with the design of the counterweight block. With the outflow of glue, the monitoring device housing is quickly fixed, thereby facilitating the micro odor monitor in the monitoring device housing to quickly monitor the gas and analyze it. At the same time, the fixing frame, slide bar, sealing plate and spring can be used to buffer and protect the micro odor monitor inside when the monitoring device housing falls to the ground to form an impact. Thereby, the service life of the micro odor monitor is improved.

[0019] 2. The present invention describes a throwable disaster site monitoring device. When the sliding rod slides and retracts with the sealing plate into the fixed frame, the sealing plate will quickly suck the external gas into the second chamber through the hose. As the spring drives the sealing plate and the sliding rod to reset, the sealing plate will squeeze part of the gas in the second chamber to re-enter the hose and flow to the monitoring probe through the breathable cloth at the through groove, thereby realizing the rapid suction of the external gas to be detected and blowing it to the monitoring probe, thereby realizing fast and efficient detection.

[0020] 3. The throwable disaster monitoring device described in the present invention slows down the outflow of glue by installing a filter, thereby effectively preventing excessive outflow of glue when the bottom frame has not yet contacted the ground. The design of the filter also allows more glue to accumulate and stay at the liquid outlet, thereby facilitating the subsequent bonding of the bottom frame to the ground. The designed arc guide plate and several guide holes allow the glue flowing out of the slide bar to be guided to both sides, so that there can also be glue at the liquid outlet away from the slide bar, thereby increasing the bonding area, and the bottom frame can achieve rapid bonding when it contacts the ground. At the same time, the guide plate can slow down the outflow of glue, avoiding the glue flowing to the liquid outlet when the monitoring equipment housing is still in the air, resulting in waste of glue and subsequent loose bonding.

[0021] 4. The throwable disaster monitoring equipment described in the present invention needs to be recycled after the monitoring equipment shell is completed. When recycling, the staff presses the monitoring equipment shell, and the degumming liquid in the fourth chamber will be sprayed into the bottom frame through the fixed tube, and then the glue will be dissolved and analyzed, so that the bonding between the bottom frame and the ground is loosened. As the monitoring equipment shell continues to be squeezed, the partition in the connecting box will squeeze the liquid in the third chamber. The liquid in the third chamber enters through the connecting tube to push the sliding rod and the blade to move toward the bonding point between the bottom frame and the ground, thereby assisting the separation of the bottom frame from the ground, and then facilitating the removal of the used monitoring equipment shell. The monitoring equipment shell will continuously squeeze the first ring and the second ring when sliding up and down, so that the gas in the first ring and the gas in the second ring are sprayed to the monitoring probe through the air guide tube. Thereby removing impurities at the monitoring probe and ensuring the sensitivity of the monitoring probe. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0045] like Figures 1 to 9 As shown, a throwable disaster site monitoring device described in an embodiment of the present invention includes a monitoring device housing 1, a miniature odor monitor 2 is installed in the monitoring device housing 1, and a monitoring probe 3 is arranged on the top of the miniature odor monitor 2; a positioning mechanism 10 is arranged in the monitoring device housing 1, and the positioning mechanism 10 includes a plurality of fixed frames 11 symmetrically fixedly installed in the monitoring device housing 1, a sealing plate 12 is sealingly and slidably connected inside the fixed frame 11, a spring 14 is fixedly installed between the sealing plate 12 and the fixed frame 11, a connecting rod 13 is fixedly installed on a side of the sealing plate 12 away from the spring 14, and an end of the connecting rod 13 away from the sealing plate 12 is fixedly connected to the miniature odor monitor 2, and the sealing plate 12 divides the fixed frame 11 into a first chamber 30 and a second chamber 40.

[0046] Specifically, a glue discharging assembly 15 is provided in the first chamber 30 of the fixed frame 11. The glue discharging assembly 15 includes a liquid storage box 151 fixedly installed in the fixed frame 11 and made of rubber material. A liquid outlet pipe 152 connected to the interior and having a one-way valve is fixedly installed on one side of the liquid storage box 151. A liquid inlet pipe 153 connected to the interior and having a one-way valve is fixedly installed on the top of the liquid storage box 151. A hollow slide bar 18 is provided at the bottom of the monitoring device housing 1. A hollow bottom frame 19 is installed at the bottom of the slide bar 18. A plurality of liquid outlet holes 20 are provided at the bottom of the bottom frame 19. The bottom frame 19 is connected to the interior of the slide bar 18. A connecting pipe 17 is installed inside the monitoring device housing 1. One end of the connecting pipe 17 is connected to the interior of the slide bar 18. The other end of the connecting pipe 17 is connected to the liquid outlet pipe 152. A counterweight 90 is fixedly installed at the bottom of the micro odor monitor 2. A blowing assembly 16 is arranged in the first chamber 30 of the fixed frame 11. The blowing assembly 16 includes a rubber box 161 fixed in the fixed frame 11. An air outlet pipe 162 connected to the inside is fixedly installed on one side of the rubber box 161. An air inlet pipe 163 connected to the inside is fixedly installed on the bottom of the rubber box 161. Check valves are installed in both the air outlet pipe 162 and the air inlet pipe 163. A limiting mechanism 60 is arranged at one end of the connecting pipe 17 in the slide rod 18. The limiting mechanism 60 includes a cover plate 61 rotatably connected to the connecting pipe 17 through a torsion spring. An arc-shaped limiting rod 62 is fixedly installed on one side of the cover plate 61. A limiting groove 63 adapted to the limiting rod 62 is provided on the surface of the connecting pipe 17.

[0047] During operation, when the area to be detected is full of harmful gases and needs to be monitored, the monitoring device housing 1 is thrown into the area to be detected. Since the monitoring device housing 1 has a built-in controller such as a Bluetooth module, the monitoring device housing 1 can be connected to an external device and the gas data subsequently monitored by the monitoring device housing 1 can be transmitted to the external device, thereby facilitating the staff to observe and analyze the gas in the area to be detected.

[0048] When the monitoring device housing 1 is thrown out, the monitoring device housing 1 is shaken first, so that the internal micro-odor monitor 2 drives the slide bar 18, the sealing plate 12 and the spring 14 to slide in the fixed frame 11, thereby using the sealing plate 12 to squeeze the liquid storage box 151 and the rubber box 161. As the detection device housing is thrown out, the micro-odor monitor 2 will shake in the monitoring device housing 1, thereby continuously squeezing the rubber box 161 and the liquid storage box 151 with the slide bar 18 and the sealing plate 12. Since the rubber box 161 is longer than the liquid storage box 151, the sealing plate 12 will first continuously squeeze the rubber box 161, causing the rubber box 161 to deform and then squeeze the internal gas into the connecting pipe 17 through the air outlet pipe 162, so as to blow the cover plate 61 and the limit rod 62 to rotate toward the limit groove 63, so that the port of the connecting pipe 17 is opened, which is convenient for the outflow of gas and subsequent glue, and the blowing can also play the role of clearing the connecting pipe 17. As the sealing plate 12 continues to slide, it will continuously squeeze the liquid storage box 151, so that the glue pre-stored in the liquid storage box 151 enters the connecting tube 17 through the liquid outlet pipe 152. Since the rubber box 161 is still being squeezed at this time, the blown gas will help push the glue to flow to the connecting tube 17, the sliding rod 18 and the liquid outlet hole 20 of the bottom frame 19 (it should be noted that according to Figure 6 As shown, it can be clearly seen that when the liquid outlet pipe 152 and the air outlet pipe 162 are connected to the connecting pipe 17, the air outlet pipe 162 is located above the liquid outlet pipe 152). As the monitoring device housing 1 falls to the ground, combined with the design of the counterweight block 90 at the bottom of the micro odor monitor 2, the monitoring device housing 1 will be shaken, and the liquid outlet hole 20 of the bottom frame 19 at the bottom will contact the ground. As glue flows out of the liquid outlet hole 20, the bottom frame 19 will be glued to the ground, thereby fixing the monitoring device housing 1 on the ground.

[0049] The designed positioning mechanism 10 can realize that when the monitoring device housing 1 is thrown into the detection area to be detected, the internal glue can flow out quickly through the cooperation of the fixing frame 11, the slide bar 18, the sealing plate 12 and the spring 14, and the design of the counterweight block 90 makes the bottom frame 19 at the bottom of the monitoring device housing 1 contact the ground, and the monitoring device housing 1 can be quickly fixed with the outflow of glue, so as to facilitate the micro odor monitor 2 in the monitoring device housing 1 to quickly monitor the gas and analyze it. At the same time, the fixing frame 11, the slide bar 18, the sealing plate 12 and the spring 14 can cooperate to well buffer and protect the internal micro odor monitor 2 when the monitoring device housing 1 falls to the ground and forms an impact. Thereby, the service life of the micro odor monitor 2 is improved.

[0050] It should be noted that a hole is provided on one side of the fixing frame 11 close to the liquid outlet pipe 152 , and a hole is also provided on the surface of the monitoring device housing 1 for gas to enter.

[0051] A hose 21 is fixedly installed on one side of the fixed frame 11, one end of the hose 21 is connected to the second chamber 40 of the fixed frame 11, and the other end of the hose 21 is outside the monitoring device housing 1. A through groove 22 is opened in the hose 21 near the monitoring probe 3, and a breathable cloth 23 is fixedly installed in the through groove 22.

[0052] During operation, when the slide bar 18 slides and retracts with the sealing plate 12 into the fixed frame 11, the sealing plate 12 will quickly suck the external gas (the external gas refers to the gas in the area to be detected) into the second chamber 40 through the hose 21, and as the spring 14 drives the sealing plate 12 and the slide bar 18 to reset, the sealing plate 12 will squeeze part of the gas in the second chamber 40 to re-enter the hose 21 and flow to the monitoring probe 3 through the breathable cloth 23 at the through groove 22, thereby realizing the rapid suction of the external gas to be detected and blowing it to the monitoring probe 3, thereby realizing fast and efficient detection.

[0053] A repulsion mechanism 50 is disposed in the fixed frame 11 . The repulsion mechanism 50 includes a first electromagnet 51 fixedly mounted in the fixed frame 11 . A second electromagnet 52 is fixedly mounted on a surface of the sealing plate 12 close to the spring 14 .

[0054] During operation, when the monitoring device housing 1 is not used, the first electromagnet 51 and the second electromagnet 52 are powered on, so that they repel each other and the sealing plate 12 does not move to the rubber box 161. This ensures that the rubber box 161 and the liquid storage box 151 are not squeezed when the monitoring device housing 1 is not used. When the monitoring device housing 1 needs to be used, it is only necessary to turn off the power to the first electromagnet 51 and the second electromagnet 52, and the sliding rod 18 can slide with the sealing plate 12 in the fixed frame 11 to squeeze the rubber box 161 and the liquid storage box 151.

[0055] A guide mechanism 70 is provided in the liquid outlet 20, and the guide mechanism 70 includes a filter screen 71 fixedly installed in the liquid outlet 20. An arc-shaped guide plate 72 is fixedly installed in the bottom frame 19, and a plurality of guide holes 73 are opened on the top of the guide plate 72.

[0056] During operation, the filter screen 71 is installed to slow down the outflow of glue, thereby effectively preventing the glue from flowing out excessively before the bottom frame 19 contacts the ground. The design of the filter screen 71 also allows more glue to accumulate and stay at the liquid outlet 20, thereby facilitating the subsequent bonding of the bottom frame 19 to the ground. The designed arc-shaped guide plate 72 and several guide holes 73 allow the glue flowing out of the slide bar 18 to be guided to both sides, so that there can also be glue at the liquid outlet 20 away from the slide bar 18, thereby increasing the bonding area, and the bottom frame 19 can achieve the effect of rapid bonding when it contacts the ground. At the same time, the guide plate 72 can slow down the outflow of glue, avoiding the glue from flowing to the liquid outlet 20 when the monitoring equipment housing 1 is still in the air, resulting in waste of glue and subsequent loose bonding.

[0057] The monitoring device housing 1 is provided with a glue removal mechanism 80, which includes a connection box 83 fixedly mounted on the top of the bottom frame 19 and made of rubber material, and the connection box 83 is connected to the inside of the slide bar 18 through a fixed tube 84. A first ring 81 and a second ring 82 are fixedly mounted on the surface of the slide bar 18, the first ring 81 is inside the monitoring device housing 1, the second ring 82 is outside the monitoring device housing 1, and the second ring 82 is between the slide bar 18 and the connection box 83.

[0058] Specifically, the connection box 83 is provided with an auxiliary component 85, which includes a partition 851 fixedly installed in the connection box 83, and the partition 851 divides the connection box 83 into a third chamber 852 and a fourth chamber 853. A connecting pipe 854 connected to the third chamber 852 is fixedly installed on one side of the connection box 83, and a sliding rod 855 is slidably connected to one end of the connecting pipe 854 through an elastic rope 856, and a blade 857 is rotatably connected to one end of the sliding rod 855 through a ball head. The first ring 81 and the second ring 82 are both hollow and made of elastic material. The first ring 81 and the second ring 82 are respectively connected to an air guide tube 86, and one end of the air guide tube 86 is aligned with the monitoring probe 3.

[0059] During operation, by designing the first ring 81 and the second ring 82 on the surface of the slide bar 18, the slide bar 18 cannot slide freely in the monitoring device housing 1. When the monitoring device housing 1 is completed, it needs to be recycled. At this time, the monitoring device housing 1 is in a state of bonding with the ground. When recycling, the staff presses the monitoring device housing 1 so that the bottom of the monitoring device housing 1 presses the connection box 83 and the first ring 81. After the connection box 83 is squeezed again, the glue removal liquid in the fourth chamber 853 inside it will be sprayed into the bottom frame 19 through the fixed pipe 84, and then the glue will be dissolved and analyzed, so that the bonding between the bottom frame 19 and the ground becomes loose. As the monitoring device housing 1 continues to be squeezed, the partition 851 in the connection box 83 will be driven to squeeze the liquid in the third chamber 852. The liquid in the third chamber 852 enters through the connecting pipe 854 to push the sliding rod 855 and the blade 857 to move to the bonding point between the bottom frame 19 and the ground, thereby assisting the separation of the bottom frame 19 from the ground, and then facilitating the removal of the used monitoring device housing 1. It should be noted that when the third chamber 852 is not squeezed, the liquid in the connecting tube 854 will return to the third chamber 852 for next use. When the monitoring device housing 1 slides up and down, it will continuously squeeze the first ring 81 and the second ring 82, so that the gas in the first ring 81 and the gas in the second ring 82 are sprayed to the monitoring probe 3 through the air guide tube 86. In this way, impurities in the monitoring probe 3 are removed to ensure the sensitivity of the monitoring probe 3.

[0060] Working principle: When the area to be detected is full of harmful gases and needs to be monitored, the monitoring device housing 1 is thrown into the area to be detected. Since the monitoring device housing 1 has a built-in controller such as a Bluetooth module, the monitoring device housing 1 can be connected to the external device for use. When the monitoring device housing 1 has not been used, the first electromagnet 51 and the second electromagnet 52 are energized to repel each other, and the sealing plate 12 will not move to the rubber box 161. This ensures that the rubber box 161 and the liquid storage box 151 will not be squeezed when the monitoring device housing 1 is not in use. When the monitoring device housing 1 needs to be used, it is only necessary to cut off the power to the first electromagnet 51 and the second electromagnet 52, and the slide bar 18 can slide with the sealing plate 12 in the fixed frame 11 to squeeze the rubber box 161 and the liquid storage box 151. When the monitoring device housing 1 is thrown out, the monitoring device housing 1 is shaken first, so that the internal micro odor monitor 2 drives the slide bar 18, the sealing plate 12 and the spring 14 to slide in the fixed frame 11, thereby using the sealing plate 12 to squeeze the liquid storage box 151 and the rubber box 161. As the detection device housing is thrown out, the micro odor monitor 2 will shake in the monitoring device housing 1, thereby driving the slide bar 18 and the sealing plate 12 to continuously squeeze the rubber box 161 and the liquid storage box 151. Since the rubber box 161 is longer than the liquid storage box 151, the sealing plate 12 will first continuously squeeze the rubber box 161, causing the rubber box 161 to deform and then squeeze the internal gas through the outlet pipe 162 into the connecting pipe 17, which blows the cover plate 61 and drives the limit rod 62 to rotate toward the limit groove 63, so that the port of the connecting pipe 17 is opened. As the sealing plate 12 continues to slide, it will continuously squeeze the liquid storage box 151, so that the glue pre-stored in the liquid storage box 151 enters the connecting tube 17 through the liquid outlet pipe 152. Since the rubber box 161 is still being squeezed at this time, the blown gas will help push the glue to flow to the connecting tube 17, the sliding rod 18 and the liquid outlet 20 of the bottom frame 19. As the monitoring device housing 1 falls to the ground, combined with the design of the counterweight block 90 at the bottom of the micro odor monitor 2, the monitoring device housing 1 will be shaken, and the liquid outlet 20 of the bottom frame 19 at the bottom will contact the ground. As glue flows out of the liquid outlet 20, the bottom frame 19 will be glued to the ground, thereby fixing the monitoring device housing 1 to the ground.

[0061] When the slide bar 18 slides and retracts with the sealing plate 12 into the fixed frame 11, the sealing plate 12 will quickly suck the external gas into the second chamber 40 through the hose 21. As the spring 14 drives the sealing plate 12 and the slide bar 18 to reset, the sealing plate 12 will squeeze part of the gas in the second chamber 40 to re-enter the hose 21 and flow to the monitoring probe 3 through the breathable cloth 23 at the through groove 22, thereby quickly sucking in the external gas to be detected and blowing it to the monitoring probe 3, thereby achieving fast and efficient detection.

[0062] By designing the first ring 81 and the second ring 82 on the surface of the slide bar 18, the slide bar 18 cannot slide freely in the monitoring device housing 1. When the monitoring device housing 1 is completed, it needs to be recycled. At this time, the monitoring device housing 1 is in a state of bonding with the ground. When recycling, the staff presses the monitoring device housing 1 so that the bottom of the monitoring device housing 1 presses the connection box 83 and the first ring 81. After the connection box 83 is squeezed again, the glue removal liquid in the fourth chamber 853 inside it will be sprayed into the bottom frame 19 through the fixed pipe 84, and then the glue will be dissolved and analyzed, so that the bonding between the bottom frame 19 and the ground becomes loose. As the monitoring device housing 1 continues to be squeezed, the partition 851 in the connection box 83 will be driven to squeeze the liquid in the third chamber 852. The liquid in the third chamber 852 enters through the connecting pipe 854 to push the sliding rod 855 and the blade 857 to move to the bonding point between the bottom frame 19 and the ground, thereby assisting the separation of the bottom frame 19 from the ground, and then facilitating the removal of the used monitoring device housing 1. When the monitoring device housing 1 slides up and down, it will continuously squeeze the first ring 81 and the second ring 82, so that the gas in the first ring 81 and the gas in the second ring 82 are sprayed to the monitoring probe 3 through the air guide pipe 86. In this way, impurities in the monitoring probe 3 are removed to ensure the sensitivity of the monitoring probe 3.
