Description

Technical Field

[0001] The present invention relates to the technical field of environmental monitoring, specifically a multi-dimensional trajectory infrared temperature-sensing ozone detection and positioning alarm mother ball. Background Art

[0002] With the progress of technology, ozone detection technology has been continuously developed. From the traditional chemical reagent method to the modern physical and chemical sensor methods, the sensitivity, accuracy, and real-time performance of the detection methods have been significantly improved. Currently, ozone detection technology has been widely applied in many fields such as environmental protection, industrial process control, medical and health, and indoor air quality monitoring.

[0003] In the prior art, ozone detection mainly focuses on ozone detection methods based on physical principles, such as ultraviolet photometry and electrochemistry. The ultraviolet photometry method utilizes the characteristic that ozone has a strong absorption property for ultraviolet light of a specific wavelength (such as 254 nanometers). By measuring the transmittance or absorption degree of ultraviolet light on ozone-containing air and combining with a mathematical model, the concentration of ozone is calculated. The electrochemistry method is a method that uses an electrochemical sensor to measure the current or voltage change generated by ozone between electrodes, thereby calculating the ozone concentration.

[0004] However, the existing ultraviolet photometry and electrochemistry monitoring technologies have the disadvantages of time-consuming and laborious in monitoring efficiency, and are even less able to timely judge the occurrence direction of excessive ozone concentration at individual times in the atmosphere, and are not suitable for wide promotion and use in ozone monitoring. Summary of the Invention

[0005] The purpose of the present invention is to provide a multi-dimensional trajectory infrared temperature-sensing ozone detection and positioning alarm mother ball to solve the problems raised in the above background art.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] The multi-dimensional trajectory infrared temperature-sensing ozone detection and positioning alarm mother ball includes an ozone detection mother ball housing made of corrosion-resistant and lightweight materials. A plurality of ozone-catching flying insects are arranged inside the ozone detection mother ball housing. An infrared ray temperature sensor, a detection liquid release mechanism, and a detection liquid storage container are installed on the ozone-catching flying insects.

[0008] The infrared ray temperature sensor is used for continuously monitoring the temperature change at each point on the trajectory.

[0009] The detection liquid storage container is used for storing liquid ammonia as the detection liquid.

[0010] The detection liquid release mechanism is used for releasing the detection liquid in the detection liquid storage container to the outside when flying along the trajectory.

[0011] Preferably, a data processing and alarm system is installed on the outer shell of the ozone detection mother ball. The data processing and alarm system is used to calculate the ozone concentration distribution map according to the real-time detection data of the infrared ray temperature sensor and the algorithm model, and issue an audible and visual alarm if the ozone concentration exceeds the standard.

[0012] Preferably, a power supply module is installed inside the outer shell of the ozone detection mother ball to supply power to the data processing and alarm system.

[0013] Preferably, the detection liquid release mechanism includes a connecting pipe body arranged at the head of the ozone-catching flying insect. A partition is arranged inside the connecting pipe body to divide the inside of the connecting pipe body and form an adjustment chamber and a storage chamber inside the connecting pipe body. The storage chamber is used to temporarily store the detection liquid. An adjustment airbag is arranged inside the adjustment chamber, and a pushing airbag is arranged inside the storage chamber. A communication pipeline is fixedly connected between the adjustment airbag and the pushing airbag.

[0014] Preferably, a detection liquid input pipe is connected to the storage chamber. The end of the detection liquid input pipe far away from the storage chamber is communicated with the detection liquid storage container to input the detection liquid into the storage chamber.

[0015] Preferably, one end of the connecting pipe body is provided with a closed end for closing the storage chamber. A diversion cover is fixedly connected around the closed end. An electric telescopic rod is fixedly installed on the outer surface of the connecting pipe body, and one end of the electric telescopic rod is fixedly connected to the closed end.

[0016] Preferably, a sealing ring is fixedly connected to one end of the connecting pipe body, and an annular groove for cooperating with the sealing ring is opened on the inner surface of the closed end.

[0017] Preferably, a movable plug is arranged inside the storage chamber, and a limiting ring is fixedly connected to the inner wall of the storage chamber. The limiting ring adopts a toothed design.

[0018] Preferably, a movable pressing plate is arranged inside the adjustment chamber. An L-shaped limiting plate is fixedly connected to the closed end. One end of the L-shaped limiting plate is fixedly connected to the movable pressing plate, and the L-shaped limiting plate is slidably connected to the connecting pipe body.

[0019] The beneficial effects of the present invention:

[0020] First, by emitting ozone-catching flying insects from the mother ball in multiple directions in space, the present invention can comprehensively monitor the ozone concentration in the three-dimensional space. Compared with the traditional single-point or fixed-direction detection method, the comprehensiveness and accuracy of the detection are greatly improved; and by using the infrared ray temperature sensing technology and judging the temperature difference on the trajectory line, the direction of the ozone generation source can be accurately traced and positioned, providing strong support for the investigation and treatment of pollution sources.

[0021] Second, the ozone-capturing flying insect proposed by the present invention flies along a preset trajectory line and releases a detection liquid, which reacts rapidly with ozone. Combined with a temperature sensor to record the temperature change in real time, rapid detection of ozone concentration is achieved. This instant detection ability helps to timely discover potential ozone pollution risks. At the same time, through the infrared ray temperature sensor and the data processing system inside the ozone detection mother ball housing, infrared temperature sensing and data processing are realized, and minute temperature changes can be accurately measured, thereby achieving sensitive detection of low-concentration ozone and improving the accuracy and reliability of detection.

[0022] Third, when the closed end is opened in the present invention, the pushing airbag can expand and squeeze the movable plug, and the movable plug pushes the detection liquid inside the accommodating chamber to flow out rapidly. This can not only ensure that the same amount of detection liquid is released each time, but also shorten the outflow time of the detection liquid, enabling the ozone-capturing flying insect to complete the release of the detection liquid at the points on the set trajectory only by decelerating without stopping. After being released, the detection liquid can be quickly diverted and diffused in all directions under the action of the diversion cover, making the detection liquid more evenly released at the corresponding points.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0032] The multi-dimensional trajectory infrared temperature sensing ozone detection and positioning alarm mother ball includes an ozone detection mother ball housing 1 made of corrosion-resistant and lightweight materials. A plurality of ozone-catching flying insects 4 are arranged inside the ozone detection mother ball housing 1. An infrared ray temperature sensor 5, a detection liquid release mechanism 6 and a detection liquid storage container 7 are installed on the ozone-catching flying insects 4;

[0033] The infrared ray temperature sensor 5 is used to continuously monitor the temperature changes at each point on the trajectory;

[0034] The detection liquid storage container 7 is used to store liquid ammonia as the detection liquid;

[0035] The detection liquid release mechanism 6 is used to release the detection liquid in the detection liquid storage container 7 to the outside when flying along the trajectory.

[0036] As Figure 1 and Figure 2 , both the ozone-catching flying insects 4 and the ozone detection mother ball housing 1 have communication modules, which can realize data transmission. The infrared ray temperature sensor 5 carried by the ozone-catching flying insects performs high-precision and non-contact real-time monitoring on the temperature changes in the target area along the preset trajectory. The flying insects fly along this trajectory and release the detection liquid, and the measurement data is transmitted to the data processing and alarm system 2 for analysis.

[0037] The ozone detection mother ball housing is made of corrosion-resistant and lightweight materials to protect the internal components from the external environment. The housing is provided with a launch port and an infrared window, which are used to launch flying insects and infrared rays respectively.

[0038] Inside the cue ball, there are a control system circuit board, a power module, an infrared emitter assembly, etc. The control system is responsible for overall control, the power module provides stable power support, and the infrared emitter is responsible for emitting infrared rays.

[0039] A data processing and alarm system 2 is installed on the outer shell 1 of the ozone detection cue ball. The data processing and alarm system 2 is used to calculate the ozone concentration distribution map based on the real-time detection data of the infrared ray temperature sensor 5 and the algorithm model. If the ozone concentration exceeds the standard, it will emit an audible and visual alarm.

[0040] The data processing and alarm system 2 is integrated by a data processing system and an alarm system, and their functions are as follows:

[0041] Data processing system: Design a wireless data transmission system to receive the temperature data from the ozone-catching flying insect, analyze the temperature difference through the algorithm, judge the ozone concentration difference and the direction of the source, and trigger the alarm mechanism when an anomaly is detected.

[0042] Alarm system: Includes various alarm methods such as sound and light flash, and is used to issue an alarm in time when the ozone concentration exceeds the standard.

[0043] The alarm device in the alarm system is installed at a prominent position outside the outer shell 1 of the ozone detection cue ball or transmitted to the personnel control area through the communication module to ensure that it can attract attention quickly when an alarm occurs. The alarm device is closely connected to the data processing system to ensure that the alarm mechanism can be triggered quickly when an anomaly is detected, and relevant personnel can be reminded to take countermeasures in time, effectively avoiding the occurrence of ozone pollution accidents.

[0044] A power module 3 is installed inside the outer shell 1 of the ozone detection cue ball to supply power to the data processing and alarm system 2.

[0045] The detection liquid release mechanism 6 includes a connecting pipe body 11 provided at the head of the ozone-catching flying insect 4. A partition 12 is provided inside the connecting pipe body 11. The partition 12 is used to divide the inside of the connecting pipe body 11 and form an adjustment chamber and a storage chamber inside the connecting pipe body 11. The storage chamber is used to temporarily store the detection liquid. An adjustment airbag 13 is provided inside the adjustment chamber, and a push airbag 14 is provided inside the storage chamber. A communication pipeline 15 is fixedly connected between the adjustment airbag 13 and the push airbag 14.

[0046] As Figure 3 、 Figure 4 and Figure 5 , the connecting pipe body 11 is located at the head of the ozone-catching flying insect 4. One end of the connecting pipe body 11 that is closed faces the air flow direction. There is an opening at the center of the partition 12, so that the connecting pipe body 11 can pass through the partition 12 to communicate the push airbag 14 and the adjustment airbag 13, enabling air flow interaction between the push airbag 14 and the adjustment airbag 13.

[0047] A detection liquid input pipe 16 is connected to the accommodation bin. One end of the detection liquid input pipe 16 far from the accommodation bin is communicated with a detection liquid storage container 7, and is used for inputting the detection liquid into the interior of the accommodation bin.

[0048] Such as Figure 2 、 Figure 4 and Figure 5 , a submersible pump is arranged inside the detection liquid storage container 7 and is connected to the detection liquid input pipe 16, and can input the detection liquid inside the detection liquid storage container into the interior of the accommodation bin through the detection liquid input pipe 16.

[0049] One end of the connecting pipe body 11 is provided with a closing end head 17 for closing the accommodation bin. A diversion cover 18 is fixedly connected around the closing end head 17. An electric telescopic rod 19 is fixedly installed on the outer surface of the connecting pipe body 11, and one end of the electric telescopic rod 19 is fixedly connected to the closing end head 17.

[0050] Such as Figure 3 and Figure 4 , the electric telescopic rod 19 draws power from inside the ozone-catching flying insect 4, and at the same time drives the closing end head 17 to move. The closing end head 17 can close the opening of the accommodation bin, and the arc-shaped diversion cover 18 can play a role in diversion, so that the sprayed detection liquid is sprayed more evenly around.

[0051] One end of the connecting pipe body 11 is fixedly connected with a sealing ring 20, and an annular groove 21 for cooperating with the sealing ring 20 is opened on the inner surface of the closing end head 17.

[0052] Such as Figure 3 、 Figure 4 and Figure 5 , when the closing end head 17 closes the connecting pipe body 11, the sealing ring 20 can be clamped into the annular groove 21 to improve the sealing performance of the accommodation bin.

[0053] An activity plug 22 is arranged inside the accommodation bin, and a limiting ring 24 is fixedly connected to the inner wall of the accommodation bin. The limiting ring 24 adopts a toothed design.

[0054] Such as Figure 5 , the periphery of the activity plug 22 closely adheres to the inner wall of the accommodation bin, which can play a role in movable sealing. The toothed design of the limiting ring 24 can play a role in dispersing the detection liquid around, and has a pressurizing effect on the detection liquid flowing around.

[0055] An activity pressing plate 25 is arranged inside the adjustment bin. An L-shaped limiting plate 26 is fixedly connected to the closing end head 17. One end of the L-shaped limiting plate 26 is fixedly connected to the activity pressing plate 25, and the L-shaped limiting plate 26 is slidably connected to the connecting pipe body 11.

[0056] Such asFigure 3 and Figure 5 A chute is provided on the connecting pipe body 11 to enable the horizontal movement of the L-shaped limiting plate 26 and the flow guiding cover 18 relative to the connecting pipe body 11, and the L-shaped limiting plate 26 drives the movable pressing plate 25 to move together inside the adjustment chamber.

[0057] Before the detection liquid needs to be sprayed, the detection liquid inside the detection liquid storage container 7 is input into the accommodation chamber through the detection liquid input pipe 17 on the side of the movable plug 22 away from the pushing air bag 14. After the accommodation chamber is filled with the detection liquid, the input of the detection liquid is stopped;

[0058] Then, the electric telescopic rod 19 can push the closed end 17, so that the closed end 17 moves away from the connecting pipe body 11. The detection liquid inside the accommodation chamber can flow out to the outside. At the same time, the closed end 17 drives the movable pressing plate 25 to move together through the L-shaped limiting plate 26. The movable pressing plate 25 presses the adjustment air bag 13, and the gas inside the adjustment air bag 13 is filled into the pushing air bag 14. The pushing air bag 14 expands and pushes the movable plug 22, so that the movable plug 22 can push the detection liquid inside the accommodation chamber. The detection liquid flows out of the accommodation chamber more quickly under the push of the movable plug 22.

[0059] The released detection liquid will be sprayed onto the closed end 17, and after being guided by the flow guiding cover 18, it will spread around. At the same time, the flow guiding cover 18 can block the airflow in the flight direction of the ozone-catching flying insect 4, avoiding the released detection liquid being quickly and widely blown away by the airflow in the flight direction of the ozone-catching flying insect 4.

[0060] The working principle of the multi-dimensional trajectory infrared temperature-sensing ozone detection and positioning alarm mother ball provided by the present invention is as follows:

[0061] The set flight speed of the ozone-catching flying insect 4 is 20 - 30 km / h. After receiving the launch command, the ozone-catching flying insect 4 flies along the preset trajectory line through the built-in propulsion device, and releases the detection liquid at the designated position to react with ozone. A high-precision and lightweight infrared ray temperature-sensing sensor 5 is installed on the ozone-catching flying insect 4, which is used to receive the infrared radiation in the target area and convert it into temperature data.

[0062] According to the monitoring requirements, the trajectory can be designed to be radially distributed or distributed along a specific path (such as rivers, roadsides, factory areas). For complex terrains or large areas, a spherical distribution strategy can also be considered, and comprehensive coverage can be achieved through the collaborative work of multiple ozone-catching flying insects 4.

[0063] Infrared rays have a strong thermal effect and can be received by an infrared detector and converted into temperature information that can be processed. The infrared ray emitter is installed on the ozone-catching flying insect 4, and along a preset trajectory, it can conduct high-precision and non-contact real-time monitoring of the temperature changes in the target area. The ozone-catching flying insect 4 flies along this trajectory and releases the detection liquid, and the measurement data is transmitted to the data processing system for analysis. The infrared ray temperature sensor 5 carried by the ozone-catching flying insect 4 can directly capture the infrared radiation in the target area without considering the visibility problem of infrared rays.

[0064] Compared with the related technologies, the multi-dimensional trajectory infrared temperature-sensing ozone detection and positioning alarm main ball provided by the present invention has the following beneficial effects:

[0065] By launching the ozone-catching flying insect 4 along multiple directions in space (such as a specific path or spherical shape), the present invention can achieve comprehensive monitoring of the ozone concentration in the three-dimensional space. Compared with the traditional single-point or fixed-direction detection method, it greatly improves the comprehensiveness and accuracy of the detection; and by using the infrared ray temperature-sensing technology and judging the temperature difference on the trajectory line, it can accurately track and locate the direction of the ozone generation source, providing strong support for the investigation and treatment of pollution sources.

[0066] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
