Abstract
Description
Technical Field
[0001] This utility model relates to the field of detection and alarm technology, specifically a portable VOCs online detection and alarm device. Background Technology
[0002] VOCs detectors are widely used to continuously measure toxic and harmful organic gases in hazardous or industrial environments. They are suitable for personal safety protection and on-site VOCs detection. VOCs emission monitoring mainly involves industries such as petrochemicals, organic chemicals, pharmaceutical manufacturing, industrial coating, machinery manufacturing, packaging and printing, electronics production, synthetic leather, paints and coatings, garment processing, furniture manufacturing, adhesives, shoemaking, and oil storage and transportation. VOCs emissions are characterized by fugitive emissions and organized emissions from stationary pollution sources, a wide variety of pollutants, large concentration variations, and uncertain emission times.
[0003] The VOC online detection alarm device disclosed in Chinese Patent Publication No. CN219775256U includes an annular plate. An annular electric slide rail is fixedly connected to the upper end of the annular plate. An electric slider is fixedly connected to the outer wall of the annular electric slide rail. A detection body is installed on the upper end of the electric slider, and a buzzer is installed on the upper end of the detection body. The annular plate can fix the annular electric slide rail, and the annular electric slide rail can drive the electric slider to move in a circle, thereby allowing the electric slider to drive the detection body to move in a circle, and thus allowing the detection body to monitor different positions in the surrounding area.
[0004] The above-mentioned device adjusts the height of the detection body by the cooperation of the lead screw and the slider, and adjusts the angle of the detection body by the cooperation of the annular electric slide rail and the electric slider, thus playing a detection role at different positions. However, since the length of the lead screw and the moving trajectory of the annular electric slide rail are relatively fixed, it is not convenient to retract and fold the device when the detection alarm is not in use or when it needs to be moved, making it inconvenient to carry. Therefore, it is necessary to propose a portable VOCs online detection alarm. Utility Model Content
[0005] The purpose of this invention is to provide a portable VOCs online detection and alarm device, which features the ability to be folded and retracted for easy carrying.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a portable VOCs online detection alarm, comprising a base and a rectangular plate. Two vertically staggered rotating shafts are rotatably connected to the front end face of the rectangular plate. The two rotating shafts are connected by a belt. Gears are fixedly connected to the outer walls of both rotating shafts. Racks are meshed with the outer walls of both gears. A support plate is fixedly connected to the upper end face of the rack on the left end. A mounting frame is fixedly connected to the upper end face of the support plate. A first motor is installed inside the mounting frame. The output end of the first motor passes through the mounting frame and is fixedly connected to a turntable. A vertical plate is fixedly connected to the upper end face of the turntable. An electric push rod is installed at the left end of the vertical plate. The output end of the electric push rod passes through the vertical plate and is fixedly connected to a mounting plate. A detection body is installed on the upper end face of the mounting plate. The lower end of the rack on the right end is fixedly connected to the base.
[0007] The front end face of the rectangular plate is provided with a driving mechanism.
[0008] In order to drive the upper rotating shaft to rotate, as a preferred embodiment of the portable VOCs online detection alarm of this utility model, the driving mechanism includes an L-shaped plate fixedly connected to the rectangular plate, a second motor installed at the upper end of the L-shaped plate, and the output end of the second motor passing through the L-shaped plate and fixedly connected to the upper rotating shaft.
[0009] In order to limit the movement of the two racks, as a preferred embodiment of the portable VOCs online detection alarm of this utility model, T-shaped grooves are provided on both the left and right sides of the rectangular plate, and sliders that are slidably connected to the T-shaped grooves are fixedly connected to the opposite sides of the two racks.
[0010] In order to limit the movement limit position of the rack, as a preferred embodiment of the portable VOCs online detection alarm of this utility model, a limit rod is fixedly connected to the opposite side of both racks.
[0011] To serve as an alarm, the portable VOCs online detection alarm of this utility model preferably has an alarm installed on the upper surface of the detection body.
[0012] In order to control the operation of each component, a controller is preferably installed on the right end of the rack located on the right end of the portable VOCs online detection and alarm device of this utility model.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] This utility model uses a drive mechanism to drive a connected rotating shaft to rotate. When the rotating shaft rotates, it drives another rotating shaft to rotate via a belt, which in turn drives two gears to rotate. When the gears rotate, they drive the racks that mesh with them to move, thereby adjusting the height of the detection body. When not in use, the drive mechanism drives the rotating shaft to rotate in the opposite direction, shrinking and folding the two racks and the rectangular plate.
[0015] Additionally, the mounting plate and detection body can be moved by an electric actuator to adjust the position of the detection body's surroundings. A first motor drives the turntable and the detection body to rotate, allowing for detection of different areas. When not in use, the detection body can be retracted and reset using the electric actuator, reducing its footprint. In summary, this design allows the detection alarm to be folded and retracted for easy portability. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.
[0021] Please see Figures 1 to 3A portable VOCs online detection alarm includes a base 1 and a rectangular plate 2. Two vertically staggered rotating shafts 4 are rotatably connected to the front end of the rectangular plate 2. The two rotating shafts 4 are connected by a belt. Gears 5 are fixedly connected to the outer walls of both rotating shafts 4. Racks 3 are meshed with the outer walls of both gears 5. A support plate 6 is fixedly connected to the upper end of the rack 3 on the left. A mounting frame 7 is fixedly connected to the upper end of the support plate 6. A first motor 8 is installed inside the mounting frame 7. The output end of the first motor 8 passes through the mounting frame 7 and is fixedly connected to a turntable 9. A vertical plate is fixedly connected to the upper end of the turntable 9. An electric push rod 10 is installed at the left end of the vertical plate. The output end of the electric push rod 10 passes through the vertical plate and is fixedly connected to a mounting plate 11. A detection body 12 is installed on the upper end of the mounting plate 11. The lower end of the rack 3 on the right is fixedly connected to the base 1. A drive mechanism is provided on the front end of the rectangular plate 2.
[0022] In this embodiment: during use, the drive mechanism drives the connected rotating shaft 4 to rotate. When the rotating shaft 4 rotates, it drives another rotating shaft 4 to rotate via a belt, thereby driving two gears 5 to rotate. When the gears 5 rotate, they drive the meshing rack 3 to move. When the upper gear 5 rotates, it drives the left rack 3 to move upward, and when the lower gear 5 rotates, it drives the rectangular plate 2 to move upward. This allows the mounting bracket 7, the first motor 8, the turntable 9, the electric push rod 10, the mounting plate 11, and the detection body 12 to move upward, thereby adjusting the height of the detection body 12. When not in use, the drive mechanism drives the rotating shaft 4 to rotate in the opposite direction, retracting and folding the two racks 3 and the rectangular plate 2 to the desired position. Figure 1 As shown. In addition, the mounting plate 11 and the detection body 12 can be moved by the electric push rod 10 to adjust the position of the detection body 12. The turntable 9 and the detection body 12 can be rotated by the first motor 8 (the first motor 8 is a forward and reverse motor) to detect different positions around the body. When not in use, the detection body 12 can be retracted and reset by the electric push rod 10 to reduce the space occupied.
[0023] As a technical optimization of this utility model, the driving mechanism includes an L-shaped plate 17 fixedly connected to the rectangular plate 2, a second motor 18 installed at the upper end of the L-shaped plate 17, and the output end of the second motor 18 passing through the L-shaped plate 17 and fixedly connected to the upper rotating shaft 4.
[0024] In this embodiment: the L-shaped plate 17 is used to support the second motor 18, which can drive the upper shaft 4 to rotate.
[0025] As a technical optimization of this utility model, T-shaped grooves 15 are provided on both the left and right sides of the rectangular plate 2, and sliders 16 that are slidably connected to the T-shaped grooves 15 are fixedly connected to the opposite sides of the two racks 3.
[0026] In this embodiment, the T-shaped groove 15 is slidably connected to the slider 16, which can limit the movement of the two racks 3 and increase the stability of the movement of the racks 3.
[0027] As a technical optimization of this utility model, the two racks 3 are fixedly connected to the opposite sides of each rack 3 with a limit rod 14.
[0028] In this embodiment, the limit position of the rack 3 can be limited by the limit rod 14.
[0029] As a technical optimization of this utility model, an alarm 13 is installed on the upper surface of the detection body 12.
[0030] In this embodiment, the alarm 13 can serve as an alarm prompt for the detection result of the detection body 12.
[0031] As a technical optimization of this utility model, a controller is installed on the right end of the right rack 3.
[0032] In this embodiment, the controller is electrically connected to the alarm 13, the detection body 12, the first motor 8, the second motor 18, and the electric push rod 10. The controller can control the operation of the alarm 13, the detection body 12, the first motor 8, the second motor 18, and the electric push rod 10.
[0033] Working principle:
[0034] In use, the upper rotating shaft 4 is driven to rotate by the second motor 18. The rotation of shaft 4 drives another rotating shaft 4 via a belt, which in turn drives two gears 5. The rotation of gears 5 drives the meshing rack 3 to move. The rotation of the upper gear 5 drives the left rack 3 to move upwards, and the rotation of the lower gear 5 drives the rectangular plate 2 to move upwards. This allows for the upward movement of the mounting bracket 7, the first motor 8, the turntable 9, the electric push rod 10, the mounting plate 11, and the detection body 12, thereby adjusting the height of the detection body 12. When not in use, the drive mechanism drives the rotating shaft 4 to rotate in the opposite direction, retracting and folding the two racks 3 and the rectangular plate 2 to... Figure 1 As shown.
[0035] In addition, the electric push rod 10 can drive the mounting plate 11 and the detection body 12 to move, thereby adjusting the position of the detection body 12. The first motor 8 drives the turntable 9 and the detection body 12 to rotate, which can detect different positions around the body. When not in use, the electric push rod 10 can retract and reset the detection body 12 to reduce the space occupied.
