Description

Technical Field

[0001] The utility model belongs to the technical field of fire-fighting devices, and particularly relates to a flying fire-fighting device for removing smoke by plasma static electricity. Background Technique

[0002] In a modern highly industrialized society, in the fields of industrial hygiene, military, preventive medicine, air pollution, military exercises, fire scenes, natural disasters, etc., the removal of smoke, sterilization, and haze removal have received increasing attention. Smoke generally refers to the fog-like substance formed with solid dust emitted from industries as condensation nuclei (such as London smog), or the secondary pollutants formed by the photochemical reaction of hydrocarbons and nitrogen oxides (such as Los Angeles photochemical smog), which is a mixture of various pollutants. Haze is caused by an aerosol system composed of dust, sulfuric acid, nitric acid, and other particulate matters in the air, which causes visual impairment. There is a consistent seasonal trend of severe atmospheric haze, which seriously affects and threatens the physical and mental health of the people. At present, the treatment of reducing and removing atmospheric haze mainly focuses on measures such as enterprises' energy conservation and emission reduction and reducing motor vehicle emissions, but there are no effective measures for the already formed haze or air pollution; currently, most homes and living places are purified by filter materials and activated carbon adsorption. Such processes are prone to secondary pollution of raw materials, and the replacement frequency is relatively high, making it impossible to effectively treat work and living places comprehensively, and it is even more difficult to treat haze in outdoor work and living places.

[0003] For the smoke generated in a specific environment such as a fire, there is a possibility of secondary combustion due to the high environmental temperature, especially at the fire scene. Currently, a large amount of smoke is generated during a fire. Even when the combustibles stop burning, a large amount of smoke is still generated under the conditions of lack of oxygen and high temperature. Due to the enclosed area, the flue gas cannot be effectively dispersed, seriously affecting the rescue time of rescue personnel and hindering the elimination of danger and the rescue of personnel and property. In this case, in order to timely determine the real-time situation of the on-site environment, ensure that rescue personnel obtain accurate information and ensure the safety of rescue personnel, it is very necessary to provide an efficient flying fire-fighting device.

[0028] As Figure 1 and 2 shown, an embodiment of the present utility model provides a flying fire-fighting device for plasma electrostatic smoke and dust removal, including:

[0029] An aircraft system 1, including a frame 110, a flight power device 120 and a flight control system. The flight power device 120 provides power for the flight of the frame 110 and cooperates with the flight control system to control the flight state of the frame 110;

[0030] A low-temperature plasma dust removal module 2, installed below the aircraft system 1, including a honeycomb electrostatic positive and negative dust removal module 210, and dust collection filter nets 220 installed on the upper and lower sides of the honeycomb electrostatic positive and negative dust removal module 210; the low-temperature plasma dust removal module 2 is used to generate plasma, and at the same time, the formed plasma or ion wind makes the smoke and dust charged, achieving the purpose of rapid sedimentation.

[0031] A monitoring system, including an image acquisition unit, a dust sensor and a temperature sensor, is used to provide real-time environmental images and monitor the environmental temperature and dust concentration. In this embodiment, the camera 310 for image acquisition and the dust sensor 320 in the graphic acquisition unit are installed on the outer side of the honeycomb electrostatic positive and negative dust removal module 210.

[0032] As Figure 3 shown, in this embodiment, the frame 110 is a multi-axis aircraft frame, including a central plate 111, three groups of flight arms 112 symmetrically arranged along the outer edge of the central plate 111, and rotors 113 arranged at the outer ends of the flight arms 112; the flight power device 120 includes a battery 121 and a driving motor (not shown in the figure). The battery 121 is installed on the central plate 111, the driving motor is installed at the outer end of the flight arm 112, the battery 121 and the driving motor are electrically connected, and the rotor 113 is driven to rotate through the driving motor. In this embodiment, the battery 121 is a lithium battery.

[0033] In this embodiment, a ranging sensor module 114 is further installed on the outer edge of the central plate 111 for monitoring the distance to obstacles.

[0034] In this embodiment, the flight control system can adopt the flight control system of a conventional unmanned aerial vehicle, including a controller, a signal transmission unit for signal transmission, and a flight control unit for controlling the start and pause of the motor. The flight control system is communicatively connected to the terminal device to control the flight state of the frame 110.

[0035] As Figure 4 and 5 shown, the honeycomb electrostatic positive and negative dust removal module 210 includes a body housing 211, a honeycomb positive dust collecting plate 212 installed in the body housing 211, and a cathode tip module installed on the honeycomb positive dust collecting plate 212. The cathode tip module includes a plurality of needle-shaped electrode strips 213 arranged in parallel at intervals. A plurality of cathode tips 214 are arranged at intervals on each needle-shaped electrode strip 213. The cathode tips 214 extend into the honeycomb hollow of the honeycomb positive dust collecting plate 212.

[0036] In this embodiment, the needle-shaped electrode strips 213 are installed on the upper side surface of the honeycomb positive dust collecting plate 212. This setting enables each cathode tip 214 to be inserted downward into each honeycomb hollow of the honeycomb positive dust collecting plate 212.

[0037] Furthermore, the cathode tips 214 are vertically inserted downward into the honeycomb hollows of the honeycomb positive dust collecting plate 212. Among them, the bottom tip of the cathode tip 214 is in an inverted conical shape, and the included angle between the conical surface of the inverted conical tip and the vertical plane perpendicular to the honeycomb positive dust collecting plate 212 is 2-10°. This setting can make the positive and negative electric fields form an included angle with the horizontal direction, that is, form an ionic wind flowing in both the horizontal and vertical directions, which plays a role in quickly settling the soot aggregation in the space to the ground.

[0038] In this embodiment, the dust collecting filter net 220 is installed on the upper and lower sides of the honeycomb positive dust collecting plate 212, and the dust collecting filter net 220 is detachably installed on the body housing 211. According to the actual required dust prevention effect, multiple dust collecting filter nets 220 can be installed to prevent the short circuit of the honeycomb electrostatic positive and negative dust removal module 210.

[0039] Furthermore, as Figure 1 and 2As shown in the figure, the low-temperature plasma dust removal module 2 further includes a high-voltage package 230 and an inverter 240 that supply power to the module. The high-voltage package 230 and the inverter 240 are installed between the center plate 111 and the honeycomb electrostatic positive and negative dust removal module 210. A collision-proof plate 250 is also installed around the high-voltage package 230 and the inverter 240. The upper and lower ends of the collision-proof plate 250 are detachably fixed to the center plate 111 and the dust collection filter net 220 respectively. In this embodiment, the high-voltage package 230 also has an automatic protection short-circuit program to protect the high-voltage package 230 and the inverter 240.

[0040] In this embodiment, a pair of buffer brackets 260 are symmetrically installed below the low-temperature plasma dust removal module 2. The buffer brackets 260 are installed on the dust collection filter net 220 below the honeycomb electrostatic positive and negative dust removal module 210 to buffer when the fire-fighting flying device lands and protect the low-temperature plasma dust removal module 2.

[0041] The above-mentioned flying fire-fighting device using plasma electrostatic smoke removal is used for effect verification. By flying the flying fire-fighting device in a closed space, the effect of removing particulate matter is tested, and the falling rate of particulate matter is tested using a smoke generating sheet.

[0042] The low-temperature plasma dust removal module 2 of the present utility model is a high-voltage low-power module with a module power of 5W and cathode tip discharge. Specifically, the specifications of the flying fire-fighting device are 500*500*400mm, and the specifications of the transparent glass closed room for the experiment are 3000*3000*3000mm. The flying fire-fighting device is flown at the center position of the closed room, and the tip of the cathode tip of the low-temperature plasma dust removal module 2 is vertically downward. During the test, dust particle detectors are installed at intervals of 500mm above, below and on the right side of the honeycomb electrostatic positive and negative dust removal module 210 to monitor the dust removal effect of the device. Two smoke generating sheets are used to generate smoke in the closed room, and the experimental data are shown in Table 1.

[0043] Table 1 Dust particle detection data

[0044]

[0045] Observed from the on-site senses, the detector and the flying fire-fighting device in the transparent glass closed room can be clearly seen after 10s. After using two smoke generating sheets to complete the smoke generation, the concentration of pm10 in the transparent glass closed room is 249432μg / m 3 , and the concentration of pm2.5 is 216937μg / m 3 ; after 4s, the concentration is reduced to below 10mg / m at 0.5m from the device 3 , and the concentration is reduced to 15mg / m in the range of 0.5m to 1m3 Below; the concentration drops to 1 mg / m after 20 s 3 Within, the particulate matter reaches the good range of the environmental quality standard after 200 s, and reaches the excellent range of the environmental quality standard after 400 s. When using the flying fire-fighting device described in this embodiment, since the ionic wind formed by the low-temperature plasma dust removal module mainly blows from the inside to the lower space and diffuses to the surroundings, the amount of ionic wind in the upper layer is the least. Therefore, for the dust removal effect of the flying fire-fighting device, relatively speaking, the particulate matter concentration in the lower layer is the lowest, the concentration in the horizontal direction is the second, and the concentration in the upper layer direction is relatively higher; and the removal efficiency of the particulate matter concentration from near to far decreases relatively at the same time.

[0046] In summary, for the flying fire-fighting device described in the present invention, first, the position of the flying fire-fighting device is controlled by the aircraft system 1, and at the same time, effective smoke removal from the environment can be achieved, thereby improving the visibility of the environment; and in combination with the supporting sensor system, the environmental temperature and images at the rescue scene are timely transmitted to the terminal device, thereby improving the work efficiency of the rescue personnel.

[0047] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
