Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, specifically to an online VOC gas environmental monitoring device. Background Technology

[0002] Volatile organic compounds (VOCs) generally refer to organic compounds that are easily volatilized at room temperature. Common examples include benzene, toluene, xylene, ethylbenzene, styrene, formaldehyde, ketones, and alcohols. These compounds are characterized by their volatility and lipophilicity and are widely used in industries such as footwear, toys, paints and inks, adhesives, cosmetics, and interior and automotive trim materials. Volatile organic compounds have a significant impact on human health, damaging the liver, kidneys, brain, and nervous system, causing serious consequences such as memory loss, and may even be carcinogenic.

[0003] However, traditional VOC gas monitoring devices are usually simple in structure and have limited monitoring range and height. When air monitoring is required at different heights, staff need to carry the monitoring equipment to different heights, which reduces monitoring efficiency and greatly reduces the monitoring effect. Furthermore, the accuracy of the monitoring data is difficult to guarantee. Therefore, we need to propose a VOC gas environmental protection online monitoring device. Utility Model Content

[0004] The purpose of this invention is to provide an online VOC gas environmental protection monitoring device that allows for easy adjustment of the overall height of the device, reducing manual labor, and enabling the monitoring device to monitor air at different heights, thereby increasing the monitoring range, improving the efficiency of air monitoring, and enhancing the accuracy of data monitoring. Simultaneously, the device is protected to ensure usability in adverse weather conditions, thus addressing the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a VOC gas environmental protection online monitoring device, including a housing, a first lifting mechanism is provided in the inner cavity of the housing, a second lifting mechanism is installed on the first lifting mechanism, a protective mechanism is fixedly connected to the upper end of the second lifting mechanism, and a VOC gas monitor is provided in the inner cavity of the protective mechanism;

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a VOC gas environmental protection online monitoring device, including a box 1, a first lifting mechanism 2 is provided in the inner cavity of the box 1, a second lifting mechanism 3 is installed on the first lifting mechanism 2, a protective mechanism 4 is fixedly connected to the upper end of the second lifting mechanism 3, and a VOC gas monitor 5 is provided in the inner cavity of the protective mechanism 4.

[0022] The first lifting mechanism 2 includes a first motor 21, a lifting plate 26 and a first screw 24. The upper surface of the lifting plate 26 is provided with a screw hole for the first screw 24 to be threadedly connected. The lower end of the first screw 24 is fixedly connected to a driven bevel gear 25. The output shaft of the first motor 21 is drivenly connected to a rotating shaft 22. One end of the rotating shaft 22 is fixedly connected to a driving bevel gear 23 that meshes with the driven bevel gear 25. The upper surface of the lifting plate 26 is fixedly connected to a guide cylinder 27 that penetrates the housing 1.

[0023] The second lifting mechanism 3 includes a threaded sleeve 33 that is slidably inserted into the inner wall of the guide cylinder 27. The inner wall of the threaded sleeve 33 is threadedly connected to a second screw 32. The lower end of the second screw 32 passes through the lifting plate 26 and is driven by a second motor 31.

[0024] Two sets of guide rods 29 are slidably inserted on the lifting plate 26. The lower ends of the two sets of guide rods 29 are fixedly connected to a limiting ring 210 for supporting the lifting plate 26. The limiting ring 210 facilitates the restriction of the position of the lifting plate 26, preventing the lifting plate 26 from touching the first motor 21, and at the same time preventing the second motor 31 from touching the bottom of the housing 1, thus improving safety.

[0025] Two sets of guide grooves 34 are provided on the outer side of the threaded sleeve 33. Two sets of limiting strips 28 are fixedly connected to the inner wall of the guide cylinder 27 and slidably connected in the guide grooves 34. By limiting the limiting strips 28 and the guide grooves 34, the threaded sleeve 33 can be raised and lowered vertically, so as to further raise the height of the VOC gas monitor 5 and increase the range of air monitoring.

[0026] The protective mechanism 4 includes a protective cover 41 for installing the VOC gas monitor 5. The outer wall of the protective cover 41 has multiple sets of air inlets 42 arranged in a circular array. The protective cover 41 prevents the VOC gas monitor 5 from hitting obstacles when it is raised or lowered, thus improving its service life. In addition, the multiple sets of air inlets 42 improve the air circulation efficiency.

[0027] A rain shelter 43 is fixedly connected to the upper surface of the protective cover 41. An air outlet pipe 44 connected to the protective cover 41 is fixedly connected to the upper surface of the rain shelter 43. An exhaust fan 48 is installed inside the air outlet pipe 44. The air circulation efficiency is accelerated by the exhaust fan 48, thereby improving the monitoring efficiency of the VOC gas monitor 5.

[0028] Multiple sets of support rods 45 are fixedly connected to the upper end of the air outlet pipe 44. A rain cover 46 is fixedly connected to the upper end of the multiple sets of support rods 45. An air outlet gap 47 is provided between the rain cover 46 and the air outlet pipe 44. The air outlet gap 47 facilitates the exhaust fan 48 to discharge excess air and also facilitates the drying of the surface of the rain shelter 43.

[0029] A handle 6 is fixedly connected to the upper side of one side of the housing 1, and a storage drawer 7 is inserted into the lower side of one side of the housing 1. Multiple sets of omnidirectional self-locking wheels 8 are provided on the lower surface of the housing 1. The handle 6 and the omnidirectional self-locking wheels 8 improve the convenience of moving the monitoring equipment, and the storage drawer 7 facilitates the storage of tools, thus improving practicality.

[0030] In use, the first motor 21 drives the rotating shaft 22, which in turn drives the drive bevel gear 23 to mesh with the driven bevel gear 25 on the first screw 24. This causes the first screw 24 to adjust the height of the lifting plate 26, facilitating the VOC gas monitor 5 to monitor the air at higher levels. When monitoring air at even higher levels is required, the second motor 31 is activated to drive the second screw 32 to connect with the threaded sleeve 33. By limiting the limit bar 28 and the guide groove 34, the threaded sleeve 33 is raised along the limit bar 28, allowing the VOC gas monitor 5 inside the protective mechanism 4 to be adjusted to a higher position, thus increasing the gas monitoring range. The operation is simple, and the exhaust fan 48 facilitates the diversion of outside air from the external protective cover 41 through the air inlet 42 into the protective cover 41 for collection and monitoring by the VOC gas monitor 5, improving the efficiency and accuracy of air monitoring.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
