Description

Technical Field

[0001] The invention belongs to the field of waterproof monitoring cameras, and more specifically, particularly relates to a rainproof outdoor monitoring camera. Background Art

[0002] In life, cameras bring us many benefits. They can provide us with security and record any situation in our lives in real time. They can always provide us with reliable security. When illegal activities occur, the images recorded by the camera can become key evidence to help the police quickly solve the case. At the same time, the camera can also accurately record many beautiful moments in our lives, allowing us to recall those precious memories at any time. In terms of traffic management, cameras play a vital role. They can monitor the driving conditions of vehicles, detect violations in a timely manner, effectively maintain traffic order, and at the same time monitor and warn social personnel.

[0003] The prior art still has the following problems: First, the existing surveillance cameras do not have good waterproof measures, which will cause the stable operation and image quality of the cameras to be affected when working on rainy days, making it impossible for the cameras to collect information well on rainy days. In the field of public safety, blurred surveillance images may also give criminals an opportunity to take advantage of them, resulting in us not being able to solve problems well when we need to rely on surveillance data. When we want to check the situation at home through surveillance, the cameras will not work properly on rainy days, and we will not be able to observe the situation at home in time. We cannot clearly understand the situation of the elderly and children at home. This uncertainty will also make it difficult for us to feel at ease when we go out.

[0004] Second, in the existing camera waterproof technology, it is usually in a relatively sealed manner to achieve waterproofing. This method can indeed block the intrusion of rainwater to a certain extent and provide a certain degree of waterproof protection for the equipment. However, when the camera is in a relatively sealed state, the internal air cannot be effectively circulated with the outside world, and the moisture in the air will gradually accumulate inside the equipment to form moisture. Moisture will corrode the electronic components of the camera, causing circuit short circuits, corrosion and other problems, thereby affecting the normal operation of the equipment. Secondly, moisture will also blur the camera lens, reduce image quality, and affect the monitoring effect. Under the long-term action of moisture, the service life of the camera will also be greatly shortened.

[0037] Specific use of the present invention: The present invention is fixed outdoors. In the case of rainy days, the induction switch 13 senses raindrops, and the wind wheel 14 senses whether there is wind to start the switch between the dry gas tank 22 and the first cavity 30, so that the gas in the dry gas tank 22 enters the first cavity 30. At the same time, the first cavity 30 and the second cavity 39 are connected. Because the gas enters, the transparent waterproof shell 18 slides in the first cavity 30 until the transparent waterproof shell 18 contacts the dehumidification shell 56, and the transparent waterproof plate 37 slides in the second cavity 39, so that the interior of the drying cavity 40 is in a relatively sealed state. Because the transparent waterproof shell 18 and the sliding rod 49 are connected by the pull wire 43, the transparent waterproof shell 18 slides to pull the pull wire 43, and the pull wire 43 pulls the sliding rod 49, and the sliding rod 49 slides in the drying cavity 40. , so that the air channel 50 in the sliding rod 49 is connected to the opening of the dry gas tank 22, and the gas in the dry gas tank 22 flows into the drying chamber 40 through the air channel 50. The bottom of the sliding rod 49 is provided with a heating plate 21. When the gas in the dry gas tank 22 passes through, the heating plate 21 heats and dries the gas in the dry gas tank 22, and the dry gas flows to the gas flow chamber 55. At the same time, the dry gas flows into the drying chamber 40 through the holes on the wall of the drying chamber 40, so that the cold and wet gas moves downward. The cold and wet gas moves downward, and the sponge 51 on the dehumidification shell 56 absorbs the moisture in the gas. The dry gas flowing into the gas flow chamber 55 brings the moisture to the outside. At the same time, through the sliding of the sliding rod 49, the sliding rod 49 drives the fourth gear 44 to rotate, and the fourth gear 44 drives the tooth plate 46 to slide, the tooth plate 46 pushes the sliding plate 48, the sliding plate 48 slides, and the sliding plate 48 squeezes the fourth spring 47, and the gap between the fourth spring 47 and the movable rod 45 is reduced. With the squeezing of the fourth spring 47, the spiral gas path will change accordingly, and the gas flow path will increase, thereby increasing the contact time between the dry gas and the sponge 51, improving the utilization efficiency of the dry gas, allowing the dry gas to better contact the sponge 51 and more effectively bring out the moisture in the sponge 51. When the movable rod 45 slides, the connecting piece 54 pulls the baffle 52, and the baffle 52 squeezes the sponge 51, so that the moisture in the sponge 51 is better discharged. After the transparent waterproof shell 18 and the dehumidification shell 56 are in contact, the conductive block 29 and the conductive sheet 27 are in contact, and the conductive sheet 27 and the power supply 2 0 contact, the conductive sheet 27 contacts with the fan 19, driving the fan 19 to rotate, so that the external air enters the drying chamber 40, and the first demisting and dust removal is performed on the interior of the drying chamber 40. At the same time, the fan 19 drives the first gear 24 to rotate, the first gear 24 drives the second gear 25 to rotate, the second gear 25 drives the incomplete gear 26 to rotate, the incomplete gear 26 contacts with the swing rod 33, the swing rod 33 slides, and the first scraper 23 is provided on the swing rod 33. Because the incomplete gear 26 has a half convex tooth and a half without a convex tooth, when the incomplete gear 26 and the swing rod 33 are not in contact, the second spring 32 pulls the swing rod 33 to reset, and the first scraper 23 scrapes the inner wall of the drying chamber 40. The first scraper 23 and the second scraper 34 are connected.While the first scraper 23 scrapes the inner wall of the drying chamber 40, the second scraper 34 scrapes the outer wall of the drying chamber 40. At the same time, a third scraper 35 and a fourth scraper 36 are provided at one end of the first scraper 23. The third scraper 35 and the fourth scraper 36 scrape the inner and outer surfaces of the transparent waterproof plate 37 as the first scraper 23 moves, which better avoids the adverse effects of bad weather on the imaging effect of the camera 12, so that the camera 12 can also work better on rainy days.
