Description

[0002] With the development of science and technology and the increase in urban security needs, outdoor electronic monitoring equipment plays an increasingly important role in public safety, traffic management, environmental monitoring and other fields. These devices usually need to operate stably under various harsh climatic conditions, and humid environment is one of the main factors affecting the performance and life of outdoor electronic equipment.

[0003] First, moisture will condense into water on the surface of components, which will reduce the insulation performance of the equipment, because moisture will penetrate into electrical components, causing the insulation resistance of the insulating material to decrease after absorbing moisture, which may cause electrical breakdown accidents. At the same time, moisture can also combine with corrosive gases in the air to corrode metal components, which not only affects the contact performance, but also shortens the service life of the equipment. More seriously, moisture forms condensation inside the equipment, which may cause short circuits at electrical contacts or cable heads, increasing the risk of equipment failure.

DETAILED DESCRIPTION

[0037] 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.

[0038] Embodiment 1, as Figure 1 , Figure 2 and Figure 3 As shown, a moisture-proof device for outdoor electronic monitoring includes a device shell 1, a spring cover plate 4 is symmetrically arranged on the front end of the device shell 1, a cooling structure 7 is arranged in the inner cavity of the device shell 1, an exhaust structure 3 is symmetrically fixedly connected to the upper end of the cooling structure 7, an insect-proof net 2 connected to the outer surface of the device shell 1 is arranged at the lower part of the left and right ends of the cooling structure 7, a cleaning drive structure 6 is arranged in the middle of the upper end of the cooling structure 7, and a dehumidification structure 5 is symmetrically arranged in the inner cavity of the cooling structure 7.

[0039] During the operation of this embodiment, first, the external air is drawn into the device casing 1 through the insect-proof net 2 and the cooling structure 7 by the action of the exhaust structure 3, and the dust and moisture in the air are separated and the air is cooled by the action of the cooling structure 7. The cooled air is sent to the inner cavity of the device casing 1 to cool and dissipate the heat of the power module, control module and other running equipment of the electronic monitoring device, thereby reducing the temperature accumulation inside the device and preventing dust and moisture from entering the interior to cause rust and damage to the internal circuit.

[0040] It should be noted that an electronic monitoring device is installed at the lower end of the above-mentioned device casing 1, and the control module, power module and drive module of the electronic monitoring device are all within the range of action of the cooling structure 7 in the lower part of the inner cavity of the device casing 1. The electronic monitoring device is a mature technical means in the prior art, and the structure has been widely used in the prior art. It can be installed in the lower part of the device casing 1 by bolts, welding, clamping, etc. The specific installation method is determined by the model, size and installation method of the loaded equipment. The present invention will no longer display and elaborate on its detailed internal structure, operating principle, wiring and control method.

[0041] Embodiment 2: Based on embodiment 1, this embodiment utilizes a fan 31 to exhaust air outward through an L-shaped air duct 32 and an air outlet 33, and drives the airflow through the insect-proof net 2 and the dust filter component 72 and the isolation component 73 through the negative pressure effect to enter the inner cavity of the device housing 1, thereby dissipating the heat of the drive module, power module and control module contained therein, ensuring that their temperature is within a stable operating range, reducing the failure rate of the equipment, increasing the life of the equipment, and reducing the maintenance frequency.

[0042] Specifically, to achieve the functions of dust removal and dehumidification, refer to Figure 4 , Figure 5 , Figure 6 and Figure 7The cooling structure 7 includes an isolation plate 76, a mounting box 74 is fixedly connected to the lower end of the isolation plate 76, and a linkage assembly 71 that fits the insect-proof net 2 for traffic is symmetrically arranged in the inner cavity of the mounting box 74, and a dust filter assembly 72 that is fixedly connected to the inner surface of the mounting box 74 is arranged at one end of the two linkage assemblies 71 that are close to each other. An isolation assembly 73 is slidably connected to the inner surface of the mounting box 74, and the front end of the isolation assembly 73 passes through the inner cavity of the mounting box 74 and the inner cavity of the device housing 1 and extends to the position of the spring cover plate 4 on the outer surface of the device housing 1. A connecting groove 75 that is connected to the lower end is symmetrically opened at the upper end of the isolation plate 76, and a mounting groove 77 is symmetrically opened front and back on the inner surface of the mounting box 74 near the insect-proof net 2 on the same side, and a sliding groove 78 that is slidably connected to the dust filter assembly 72 is symmetrically opened on the left and right parts of the inner surface of the mounting box 74.

[0043] The dust filter assembly 72 is mainly used to filter dust to prevent dust from entering and causing a short circuit, dust from wrapping around the motor center shaft and affecting operation, and to increase the service life of the fan 31;

[0044] The isolation component 73 is mainly used to further absorb the residual moisture in the air after the dehumidification structure 5 performs dehumidification and cooling. At the same time, the cooperation between the isolation component 73, the installation box 74 and the spring cover plate 4 can facilitate the maintenance personnel to replace and maintain.

[0045] The above-mentioned spring cover plate 4 is a structure that uses the elastic force of the spring to force the sliding block to fit tightly against the inner wall of the slot, and can close the sliding slot without being subjected to external force. The maintenance personnel can open it and pull out the isolation assembly 73 by flicking it. It is a conventional closing component and has been widely used in the prior art.

[0046] Further, to realize the functions of air suction and exhaust, refer to Figure 5 and Figure 6 The exhaust structure 3 includes a plurality of fans 31 fixedly connected to the inner surface of the connecting groove 75. The upper end of the isolation plate 76 is symmetrically fixedly connected with an L-shaped air duct 32 connected to the outer surface of the device housing 1. The horizontal parts of the two L-shaped air ducts 32 are linearly distributed at one end away from each other and are connected to the inner cavity thereof. The lower end of the L-shaped air duct 32 is connected to the connecting hose 7213, and the inner surface of the L-shaped air duct 32 is fixedly connected to the dehumidification structure 5.

[0047] The fan 31 blows air upward, and can discharge the internal hot air to the outside of the equipment through the air outlet 33 through the guiding effect of the L-shaped air duct 32. At the same time, during the exhaust process, it can also dissipate heat for the dehumidification structure 5 and simultaneously remove the dust swept down by the dust filter component 72 through the suction effect of the airflow.

[0048] Embodiment 3: Based on the embodiment 2, this embodiment further utilizes the function of the dust filter 723 to filter out the dust in the air, and drives the cleaning box 7212 to slide up and down on the surface of the dust filter 723 through the cooperation of the cleaning component 721 and the cleaning drive structure 6, and drives the cleaning wheel 7214 to sweep on the surface of the dust filter 723 through the meshing action of the gear 2 7215 and the spur rack 722 during the sliding process, thereby cleaning the dust on the surface of the connecting hose 7213, reducing the dust residue on its surface, improving the filtering efficiency, and ensuring the air intake rate;

[0049] During the cleaning process, the dust on the surface is scraped off and sent into the partition 7216 through the cooperation of the cleaning wheel 7214 and the cleaning brush 7217. At the same time, through the cooperation of the elastic rope 64 and the linkage assembly 71, during the cleaning process of the cleaning component 721, the sealing plate 711 is driven to rotate to close the air inlet channel, and the continuous suction action of the fan 31 drives the connecting hose 7213 to extract the dust in the partition 7216 and send it out through the L-shaped air duct 32. No manual cleaning is required, thereby reducing the maintenance frequency.

[0050] Specifically, to achieve the isolation of dust and dirt in the incoming air, refer to Figure 6 The dust filter assembly 72 includes a dust filter net 723 fixedly connected to the inner surface of the mounting box 74, and the end of the dust filter net 723 close to the insect-proof net 2 on the same side is symmetrically fixedly connected with a straight rack 722, and the end of the dust filter net 723 close to the insect-proof net 2 on the same side is provided with a cleaning component 721 that is slidably connected to the inner surface of the slide groove 78 and rotatably connected to the cleaning drive structure 6.

[0051] The dust filter 723 is mainly used to filter out dust in the incoming air to prevent dust from entering the interior of the equipment. Dust contaminating the circuit board and battery electrodes may cause a short circuit, which may damage the components at the least and cause a fire at the worst, thus causing a safety accident.

[0052] Further, to clean the dust filter 723, refer to Figure 5 , Figure 7 , Figure 8 and Fig. 9The cleaning component 721 includes rollers 7211 symmetrically distributed front and back and rotatably connected to the cleaning drive structure 6. The outer surfaces of the two rollers 7211 are slidably connected to the inner surface of the same side slide groove 78. The ends of the two rollers 7211 close to each other are fixedly connected to a cleaning box 7212. The inner surface of the cleaning box 7212 is linearly distributed and fixedly connected to a side away from the spur rack 722. A cleaning brush 7217 is fixedly connected between two adjacent partitions 7216. The partition 7216 is close to the dust filter 723. Both ends are provided with connecting openings connecting the inner cavity of the partition 7216 and the inner cavity of the cleaning box 7212. A cleaning wheel 7214 is linearly distributed and rotatably connected to one side of the inner surface of the cleaning box 7212 close to the dust filter 723. The left and right ends of the cleaning wheel 7214 are fixedly connected to gear 2 7215. The outer surface of the gear 2 7215 on the same side is meshed with the spur rack 722 on the same side. The upper end of the cleaning box 7212 is fixedly connected to a connecting hose 7213 that is connected to the inner cavity of the partition 7216. The upper end of the connecting hose 7213 is connected to the exhaust structure 3 on the same side.

[0053] The rollers 7211 on both sides slide up and down in the slide grooves 78 on both sides under the action of the cleaning drive structure 6, and can synchronously drive the cleaning box 7212 to slide up and down on the surface of the dust filter 723. During the sliding process, since the gear 2 7215 is meshed with the spur racks 722 on both sides, it will rotate in the up and down process, thereby driving the cleaning wheel 7214 to rotate. During the rotation process, the cleaning wheel 7214 will clean the surface of the dust filter 723 and carry the dust in it to the rear part of the inner cavity of the cleaning box 7212 through the bristles;

[0054] When the cleaning wheel 7214 moves to the rear of the inner cavity of the cleaning box 7212, the cleaning brush 7217 combs the bristles of the cleaning wheel 7214 and removes the dust on its surface through the scraping teeth, and the removed dust enters the inner cavity of the partition 7216 through the negative pressure.

[0055] The reason why there is a negative pressure in the inner cavity of the partition 7216 relative to the inner cavity of the cleaning box 7212 is that the inner cavity of the partition 7216 is connected to the L-shaped air duct 32 through the connecting hose 7213. During the exhaust process of the L-shaped air duct 32, since the overall flow direction of the air flow is to exhaust outward, an outward-flowing airflow will be formed at the interface between the connecting hose 7213 and the L-shaped air duct 32, thereby drawing air from the partition 7216 and simultaneously bringing out the internal dust through the connecting hose 7213.

[0056] Further, in order to drive the linkage assembly 71 and the dust filter assembly 72 to work together, refer to Figure 4 and Figure 7The cleaning drive structure 6 includes a driving motor 61 fixedly connected to the upper end of the isolation plate 76 and an elastic rope 64 fixedly connected to the upper end of the movable plate 716. The output end of the driving motor 61 is fixedly connected to a winding shaft 62, and the winding shaft 62 is fixedly connected to the upper end of the isolation plate 76 through a bearing bracket. The front and rear parts of the outer surface of the winding shaft 62 are symmetrically wound with cables 63. The side of the cable 63 away from the winding shaft 62 is rotatably connected to the outer surface of the roller 7211 through a slip ring, and the end of the elastic rope 64 away from the movable plate 716 is fixedly connected to the cable 63.

[0057] The driving motor 61 rotates to drive the winding shaft 62 to rotate, thereby driving the cable 63 to move along a predetermined winding route through the action of the winding shaft 62 and the cable 63, thereby pulling the roller 7211 to slide downward in the slide groove 78, and during the sliding process, the linkage assembly 71 is synchronously pulled through the installation box 74 to block the air inlet channel to prevent continuous air intake from affecting the cleaning effect of the dust filter assembly 72.

[0058] Furthermore, in order to prevent the air from interfering with the cleaning action during the cleaning process, refer to Fig.10 The linkage assembly 71 includes a sealing plate 711 which is linearly distributed and rotatably connected to one side of the inner surface of the installation box 74 near the insect-proof net 2, and the left and right ends of the sealing plates 711 located on the inner side of the installation groove 77 are fixedly connected with a gear 712, and the rear parts of the outer surfaces of the gears 712 on the same side are meshed with U-shaped racks 713, and the upper and lower ends of the horizontal parts of the U-shaped racks 713 are respectively fixedly connected with a compression spring 1 715 and a compression spring 2 717, and the inner surface of the installation groove 77 is rectangularly distributed and fixedly connected with a plurality of limit plates 714, and the upper end of the compression spring 1 715 is fixedly connected with a movable plate 716, and the upper end of the movable plate 716 is fixedly connected to the cleaning drive structure 6.

[0059] If during the cleaning process, the dust filter screen 723 still continues to pass wind, it will affect the dust scraping effect of the cleaning and cleaning brush 7217. While the cable 63 drives the roller 7211 to slide downward in the slide groove 78, the elastic rope 64 will pull the movable plate 716 to rise, and during the rising process, the U-shaped rack 713 is pulled to slide upward in the installation groove 77 through the action of the compression spring 1 715, thereby driving the sealing plate 711 to rotate through the meshing action of the U-shaped rack 713 and the gear 1 712, thereby closing the air inlet channel. After closing, the U-shaped rack 713 is in contact with the limit plate 1 714, and the U-shaped rack 713 will not continue to rise. At this time, the compression spring 1 715 is stretched until the cleaning is completed and the driving motor 61 is reversed. Under the action of the compression spring 2 717, the U-shaped rack 713 is reset to fit the lower limit plate 1 714 and drive the sealing plate 711 to reset.

[0060] Embodiment 4: Based on Embodiment 3, this embodiment uses the function of the semiconductor refrigeration sheet 51 to cool the heat exchange plate 53 and the arc-shaped guide plate 54, and guides and cools the incoming normal temperature air through the heat exchange plate 53 and the arc-shaped guide plate 54, and makes the moisture in the air condense on the surface of the heat exchange plate 53 and the arc-shaped guide plate 54 under the action of low temperature, and slides downward through the water infiltration plate 55 into the water collection tank 56 under the action of gravity, and finally is collected and discharged to the outside of the equipment through the action of the drain pipe 57;

[0061] At the same time, when the humidity is too high, the low-temperature water will also evaporate to a certain extent. The isolation component 73 is filled with spherical desiccant particles, which further absorb the small amount of water evaporated by the secondary volatilization to prevent moisture from entering and causing rust and corrosion in the monitored modules.

[0062] Specifically, to achieve the treatment of water vapor and moisture in the incoming air, refer to Fig.11 and Fig.14 The dehumidification structure 5 includes a semiconductor refrigeration sheet 51 fixedly connected to the upper inner surface of the installation box 74, and a plurality of heat dissipation fins 52 are fixedly connected to the upper end of the semiconductor refrigeration sheet 51 and extend to the inner cavity of the L-shaped air duct 32 from the lower end of the L-shaped air duct 32. A plurality of heat exchange plates 53 are linearly distributed and fixedly connected to the lower end of the semiconductor refrigeration sheet 51, and a plurality of arc-shaped guide plates 54 are staggered and fixedly connected between two adjacent heat exchange plates 53.

[0063] The semiconductor refrigeration sheet 51 is a conventional semiconductor refrigeration element, which generates heat at the other end while cooling at one end. In the prior art, this element belongs to conventional technical means, and its internal structure, operating principle and wiring method will not be displayed or elaborated in the present invention.

[0064] The heat exchange plate 53 and the arc-shaped guide plate 54 are arranged at the cold end of the semiconductor cooling plate 51. The rectangular heat exchange plate 53 divides the semiconductor cooling plate 51 into multiple areas for dispersing the air sent in from the spur rack 722.

[0065] The arc guide vane 54 is arc-shaped and can guide the air flowing through the heat exchange plates 53 on both sides to move in a curve. While further increasing the heat exchange area between the cold air and the heat exchange plates 53 and the arc guide vane 54, it also prolongs the residence time of the air within the action range of the semiconductor refrigeration plate 51, thereby improving the cooling and dehumidification efficiency.

[0066] Further, in order to discharge the condensed water on the heat exchange plate 53 and the arc-shaped guide vane 54, refer to Fig.12The dehumidification structure 5 also includes a plurality of water-seepage plates 55 fixedly connected to the lower ends of the heat exchange plates 53. A water collection trough 56 is provided in an installation box 74 at the lower end of the water-seepage plate 55. A drainage pipe 57 is fixedly connected to the front end of the installation box 74 and extends through the inner cavity of the device shell 1 to the front end of the device shell 1. The water collection troughs 56 on both sides are connected to the drainage pipe 57.

[0067] The condensed water on the surface of the heat exchange plate 53 and the arc guide plate 54 will slide downward under the action of gravity and finally fall on the water infiltration plate 55. The water infiltration plate 55 is a semi-permeable membrane that is water-permeable but air-tight. Its principle is similar to that of fine cloth. Condensed water can penetrate through its gaps, but air flow cannot pass through easily. Therefore, low-temperature air will not enter the water collection tank 56 through the water infiltration plate 55. After the condensed water enters the water collection tank 56, it will gather in the water collection tank 56 and be discharged through the drain pipe 57.

[0068] Further, to achieve secondary treatment of water vapor, refer to Fig.13 The isolation assembly 73 includes a handle 733, a rear end of the handle 733 is fixedly connected to a desiccant storage box 2 732, a rear end of the desiccant storage box 2 732 is fixedly connected to a desiccant storage box 1 731, an output port of the desiccant storage box 1 731 is fixedly connected to a heat exchange plate 734, and both the desiccant storage box 2 732 and the desiccant storage box 1 731 are slidably connected to the inner surface of the installation box 74.

[0069] In order to avoid secondary evaporation of water due to air flow, a second desiccant storage box 732 and a first desiccant storage box 731 are slidably installed in the installation box 74. At the same time, in order to ensure the stability of the power supply operation, a heat exchange plate 734 is also installed at the power supply joint. The second desiccant storage box 732 and the first desiccant storage box 731 are connected together, and their air inlet ends are both close to the end of the dehumidification structure 5. The air outlet end of the second desiccant storage box 732 is located at the end away from the dehumidification structure 5, and the air outlet end of the first desiccant storage box 731 is connected to the heat exchange plate 734, which is mainly used to provide low-temperature air for the heat exchange plate 734 to exchange heat with the power module to cool it down.

[0070] The interior of the desiccant storage box 1 731 and the desiccant storage box 2 732 are filled with spherical desiccant particles, which can absorb the moisture inside when the air passes through;

[0071] However, after the condensation treatment by the front dehumidification structure 5, there is generally very little moisture. When and only when the dehumidification structure 5 is not treated in time due to excessive external humidity or secondary evaporation occurs in high temperature weather, some moisture will enter the isolation component 73. The isolation component 73 mainly serves as an insurance function.

[0072] At the same time, the spring cover 4 can be opened by sliding the isolation assembly 73 and the installation box 74, and the handle 733 can be pulled out to replace the desiccant particles therein.

[0073] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
