Description

Technical Field

[0001] This utility model relates to the field of air purification, and in particular to an outdoor air purification device with current detection and control. Background Technology

[0002] With the development of technology, field equipment has been widely used in many fields, but this has also brought about many problems. Among these, the cleaning of cameras is particularly important. The cleaning of field equipment is basically divided into two methods: manual cleaning and automatic cleaning. Manual cleaning involves manually removing dust, dirt, and contaminants from the camera, but this is inefficient. Automatic cleaning, on the other hand, is a technology that can automatically remove dust, dirt, and contaminants. It can clean the camera through mechanical devices, pneumatic systems, or liquid systems, keeping it clear and extending its lifespan. This technology greatly improves the efficiency of camera use and ensures video clarity and quality.

[0003] Firstly, outdoor cleanroom devices are widely used in the security field. As people's demand for security increases, the security industry is also constantly developing and expanding. Applying cleanroom technology to outdoor equipment can ensure the clarity of cameras and improve the quality of surveillance videos. In daily life, camera clarity is crucial for recording facts and restoring the truth, playing a vital role in achieving safe cities and providing strong support for the development of the security industry. Secondly, automatic cleaning cameras also have broad application prospects in industrial production. In industrial production, camera clarity is crucial for quality control and inspection of the production process.

[0004] By applying field cleanroom devices, the clarity and brightness of field equipment can be ensured, production efficiency and quality can be improved, and urban safety can be enhanced.

[0005] There are many shortcomings in the cleaning of field equipment, among which manual cleaning is particularly prominent. Many field equipment are installed in dangerous locations such as high altitudes, highways, and tunnels. Currently, the method of dealing with the contamination of the mirror and glass surfaces of these field equipment is mostly to use aerial work platforms to carry workers for manual cleaning.

[0006] Because the field equipment is installed at high altitudes and in harsh tunnel working environments, manual cleaning poses a risk to the personal safety of cleaning personnel. Manual cleaning of mirrors and glass surfaces can only be judged by appearance, making it difficult to guarantee the cleaning effect. Manual cleaning is inefficient and cannot determine the cleaning frequency based on the state of lens contamination, resulting in poor real-time performance. In addition, existing methods require the closure of tunnels, which interferes with traffic efficiency.

[0007] Secondly, there's automatic cleaning. Currently, the mainstream automatic cleaning method uses a combination of mechanical devices and liquid systems. The liquid system sprays cleaning fluid onto the mirrors and glass surfaces of the equipment, and then the mechanical device scrapes them. This automatic cleaning method requires consumables such as cleaning fluid and wipers. In addition, the mechanical device can wear down the lenses during long-term scraping, and it cannot guarantee that some lenses contaminated with oil will be cleaned. Furthermore, installation is inconvenient and cannot be modified later. On the other hand, pneumatic automatic cleaning devices generally use air particle separators to exhaust dirty air (heavy air) and deliver clean air (light air) to the equipment. At the dust-free window, the clean air (light air) forms a positive pressure cloud, blowing away dust, particulate matter, smoke, and other pollutants, preventing them from approaching the clean mirrors and glass surfaces. This type of cleaning device is relatively expensive, and the device is large and heavy. It can only clean one-to-one, has high installation requirements, is difficult to disassemble and assemble, has poor waterproof performance, and lacks current protection, resulting in poor safety.

[0042] In response to the problems existing in the current technology, combined with Figure 1-6 An outdoor cleanroom device with current detection and control for maintaining clean air on the surface of camera equipment 1, comprising:

[0043] The protective cover 2 houses the camera device 1, which is used to protect the camera device 1 through the protective cover 2.

[0044] The connecting pipe 3 is connected to the inside of the protective cover 2 and is used to input purified air to the surface of the camera device 1;

[0045] The purification device 4 is connected to the inside of the protective cover 2 via the connecting pipe 3, and is used to purify the outside air;

[0046] The purification device 4 can purify the outside air and input it into the protective cover 2 through the connecting pipe 3 to form an air curtain on the surface of the camera device 1, so that the surface of the camera device 1 is always kept clean.

[0047] Specifically, the purification device 4 purifies the outside air, and the purified air can be continuously input into the interior of the protective cover 2 through the connecting pipe 3, so that an air curtain is generated on the surface of the camera device 1 to prevent external dust from eroding and accumulating on the surface of the camera device 1.

[0048] In some specific embodiments, the purification device 4 includes:

[0049] 5. Outer shell;

[0050] An air inlet 6 is located on the outer casing 5 and is used to input outside air;

[0051] Primary filter 7 is located inside air inlet 6 and is used for primary filtration of outside air;

[0052] Plasma generator 8 is located on one side of primary filter 7 and is used to generate a high-energy electric field to break large dust particles into smaller dust particles.

[0053] The dust collection module 9 is located on the side of the plasma generator 8 away from the primary filter 7 and is used to filter and collect small dust particles.

[0054] The fan 10 is located on the end of the housing 5 that is connected to the connecting pipe, and is used to input outside air into the housing 5 through the air inlet 6 to provide suction.

[0055] In some specific embodiments, the dust collection module 9 is an electrostatic adsorption module.

[0056] Specifically, the fan 10 generates suction to draw outside air into the casing 5 through the air inlet 6. Large dust particles are initially filtered out by the primary filter 7. Then, the air passes through the plasma generator 8, which generates a high-energy electric field. Under the influence of the electric field gradient, a large number of electrons and negative ions collide inelastically with the particulate pollutants in the air, thus attaching to them and becoming charged ions. Utilizing the attraction between positive and negative charges, these charged ions aggregate into large particles. These particles are then carbonized and reduced in size by a high-voltage electric field. Finally, the particles adhere to the dust collection module 9. The dust collection module 9 adopts a new type of non-metallic electrostatic adsorption module that uses the dielectric barrier discharge principle (the plasma generator 8 and the dust collection module 9 based on the dielectric barrier discharge principle are existing mature solutions). It uses polymer materials as carriers and completes the structural shaping through a special process. When the air passes through the primary filter, large-diameter dust particles, hair, etc. in the air are filtered out by the primary filter. Smaller particles enter the plasma generator with the airflow and are ionized by high voltage and given a charge. When the charged particles pass through the dust collection module 9, they are adsorbed onto the dust collection module 9.

[0057] In some specific embodiments, the upper end of the outer casing 5 is hinged with a cover plate 11.

[0058] Specifically, it facilitates regular cleaning and maintenance of the equipment inside the housing 5 by opening the cover 11.

[0059] In some specific embodiments, the housing 5 is provided with a controller 12, which is electrically connected to the fan 10.

[0060] In some specific embodiments, the controller 12 is electrically connected to the switching power supply 13, one end of the switching power supply 13 is electrically connected to the positive terminal of the plasma generator 8 and the dust collection module 9, and the other end of the switching power supply 13 is electrically connected to the negative terminal of the plasma generator 8 and the dust collection module 9 through the current monitoring controller 16.

[0061] Specifically, the current monitoring controller 16 monitors the current on the line. When the high voltage current of the current detection controller 12 exceeds the set safe current or an abnormal operating current occurs, the controller 12 controls the automatic disconnection of the high voltage power supply to the plasma generator 8 and the dust collection module 9, which serves as a power outage protection function to prevent the plasma generator 8 and the dust collection module 9 from catching fire due to excessive high voltage current.

[0062] In some specific embodiments, the dust collection module 9 has a single card slot 14 on one side and a double card slot 15 on the other side, and the inner wall of the outer shell 5 has a slot that cooperates with the single card slot 14 and the double card slot 15.

[0063] Specifically, the single card slot 14 and the dual card slot 15 design prevent the dust collection module 9 from being installed backwards, and also facilitate the replacement of the dust collection module 9.

[0064] In some specific embodiments, the wiring connections between the controller 12 and the switching power supply 13 and the fan 10, the switching power supply 13 and the plasma generator 8 and the dust collection module 9, and the current detection controller 12 and the plasma generator 8 and the dust collection module 9 are connected by a snap-fit ​​connection using a foolproof terminal 17.

[0065] Specifically, the wiring is easier to install and remove, and it can also prevent the wires from coming loose.

[0066] In some specific embodiments, the upper side of the outer casing 5 is provided with a sealing strip 18 that can abut against the cover plate 11.

[0067] Specifically, the outer casing 5 has a better sealing and waterproof effect.

[0068] In some specific embodiments, combined with Figure 7 The outer shell 5, the connecting pipe 3, and the protective cover 2 are integrated into the same outer shell 5. The purified air inside the outer shell 5 can be directly sprayed onto the surface of the camera device 1, resulting in a higher degree of integration.

[0069] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
