Description

Technical Field

[0001] This invention belongs to the field of air detection technology, specifically an occupational health and environmental monitoring device for factory air. Background Technology

[0002] Factories often contain large amounts of dust or harmful gases. If the human body inhales dust or harmful gases, it can easily cause irreparable damage. In order to ensure people's safety, it is often necessary to test the air hygiene and air environment of factories.

[0003] In existing technologies, air detectors are commonly used to monitor factory air quality. These detectors typically have an external air inlet that draws in air from the factory for testing. However, factory air contains a significant amount of dust, which easily adheres to the inlet surface, causing blockages. If this dust is suddenly drawn into the detector, it can lead to inaccurate air quality readings. Furthermore, existing detectors often require regular manual cleaning of the inlet, which is inconvenient. Therefore, this paper proposes an occupational health and environmental monitoring device for factory air to address these issues. Summary of the Invention

[0008] Preferably, the top of the outer shell is fixedly connected to the cleaning box, the top of the cleaning box is provided with a water inlet pipe, and the left and right sides of the outer shell are equidistantly connected to the air venting plate.

[0009] Preferably, the side of the rotating rod away from the motor is connected to the housing bearing, a limiting piece is provided in the middle of the rotating rod, and the winding of the pull ropes on the left and right sides is opposite.

[0010] Preferably, the middle part of the interior of the outer shell is rotatably connected to the limiting rod, the side of the movable rod away from the limiting rod is hinged to the connecting rod, and both the front and rear sides of the interior of the outer shell are movably engaged with the connecting rod.

[0011] Preferably, the top of the water inlet pipe is fixedly connected to the cleaning box, the top of the second spring is fixedly connected to the cleaning box, and water permeable holes are equidistantly opened on the side of the water inlet pipe near the air intake component. The length values ​​of the first baffle and the second baffle are both greater than the water permeable holes. The first baffle is located above the water permeable holes, and the first limiting plate and the second limiting plate are both movably engaged with the water inlet pipe.

[0012] Preferably, the first limiting plate includes a rectangular plate, the side of the rectangular plate near the fixed plate is fixedly connected to the first spring, and the other side of the rectangular plate is fixedly connected to a clamping plate at equal intervals. The side of the clamping plate away from the fixed plate is provided with an inclined surface adapted to the top of the first baffle, and the side of the second limiting plate away from the fixed plate is provided with an inclined surface adapted to the second baffle.

[0013] Preferably, the front and rear ends of the bottom of the second connecting plate are fixedly connected to the connecting rod.

[0014] Preferably, the wiping block has a sponge layer on the side near the air intake plate, the outer side of the wiping block is made of metal material, and the air intake plates on both sides are inclined downward from left to right.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] This invention utilizes a combination of a wiping block, a cleaning box, a water pipe, a fixing plate, a first spring, and a first limiting plate to facilitate cleaning. A movable rod moves a connecting rod on one side downwards, causing the air-guiding plate to tilt and allowing the wiping block to slide towards the water injection assembly. The connecting rod then moves a second connecting plate downwards, which in turn moves a second water-blocking plate downwards, opening the water-permeable holes. Water then wets the wiping block through the water-permeable holes in the water pipe. The limiting rod moves the connecting rod upwards, causing the air-guiding plate to rotate in the opposite direction. The wiping block slides downwards under its own weight, and the sponge layer of the wiping block effectively wipes away dust from the surface of the air-guiding plate.

[0017] This invention utilizes a combination of components such as an air intake plate, a connecting rod, a motor, a rotating rod, and a pull rope to achieve excellent detection results. The motor drives the rotating rod to rotate, which unwinds the pull rope on one side while winding it on the other. This allows the pull rope to pull the limiting rod to one side, and the limiting rod, through a movable rod, drives the wiping block, causing the air intake plate on one side to draw air upwards for detection, and the air intake plate on the other side to draw air downwards for detection, thus improving the detection performance of the device.

[0018] This invention enables the device to quantitatively discharge clean water through a second limiting plate, a first baffle, a first connecting plate, and a second spring. The second baffle presses down against the second limiting plate, pushing the first limiting plate and compressing the fixed plate, preventing the first limiting plate from contacting the first baffle. The spring force of the second spring, through the first connecting plate, pushes the first baffle downwards, blocking the water permeability hole. When the connecting rod moves the second connecting plate upwards, the second baffle moves upwards and contacts and pushes the first baffle. The first baffle contacts and presses against the inclined surface of the first limiting plate, and the spring force of the fixed plate allows the first baffle to reset, enabling the device to quantitatively discharge clean water.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figures 1 to 8 As shown, the present invention provides an occupational health and environmental monitoring device for factory air, including a housing 1. A motor 3 is fixedly connected to both the front and rear ends inside the housing 1. A rotating rod 4 is fixedly connected to the output end of the motor 3. Pull ropes 5 are wound around both sides of the rotating rod 4. A limiting rod 6 is fixedly connected to the top of the pull ropes 5. Movable rods 7 are movably engaged inside both sides of the limiting rod 6. An air intake assembly 2 is hinged to the other side of the movable rod 7. A water injection assembly 9 is fixedly connected to the bottom of the air intake assembly 2. A cleaning box 8 is fixedly connected to the top of the water injection assembly 9.

[0030] The motor 3 drives the rotating rod 4 to rotate, which can untangle the pull rope 5 on one side and wrap the pull rope 5 on the other side. This allows the pull rope 5 to pull the limiting rod 6 to tilt to one side, making the limiting rod 6 higher on one side and lower on the other. This allows the air intake components 2 on both sides to rotate. The air intake components 2 can guide the air. It is worth noting that the housing 1 is equipped with an air detector, which can absorb air for detection. This is existing technology and will not be elaborated further.

[0031] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the water injection assembly 9 includes a water inlet pipe 901. A fixing plate 902 is fixedly connected to the middle of the water inlet pipe 901 near the limiting rod 6. A first spring 903 is fixedly connected at equal intervals to the fixing plate 902 near the water inlet pipe 901. A first limiting plate 904 is fixedly connected to the other side of the first spring 903. A second limiting plate 905 is fixedly connected at equal intervals to the side of the first limiting plate 904 away from the limiting rod 6. A second baffle plate 910 is movably connected to the other side of the second limiting plate 905 away from the limiting rod 6. A first baffle plate 906 is movably latched to the top side of the first limiting plate 904. A first connecting plate 907 is fixedly connected to both the front and rear ends of the first baffle plate 906. A second spring 908 is fixedly connected at equal intervals to the top of the first connecting plate 907. A second connecting plate 909 is fixedly connected to both the front and rear ends of the second baffle plate 910.

[0032] The second baffle plate 910 presses down against the second limiting plate 905, pushing the first limiting plate 904 and compressing the fixing plate 902. The first limiting plate 904 then stops contacting the first baffle 906. The elastic force of the second spring 908 pushes the first baffle 906 downwards through the first connecting plate 907, causing it to block the water permeable hole. When the second connecting plate 909 moves upwards, the second baffle plate 910 moves upwards and contacts the first baffle 906, pushing it. The first baffle 906 then contacts and presses against the inclined surface of the first limiting plate 904. The elastic force of the fixing plate 902 allows the first baffle 906 to reset, enabling the device to discharge a measured amount of clean water. It is worth noting that... Figure 3 and Figure 5 The water injection component 9 in the middle, due to Figure 3 The connecting rod 202 pulls the second connecting plate 909 downwards, while Figure 5 The connecting rod 202 pulls the second connecting plate 909 upward, which is the two different working states generated by the connecting rod 202 moving upward and downward.

[0033] like Figure 2 , Figure 7As shown, the air intake assembly 2 includes an air intake plate 201. A wiping block 203 is movably engaged on the outer side of the air intake plate 201. A connecting rod 202 is hinged to the side of the air intake plate 201 near the water injection assembly 9. The left and right sides of the outer shell 1 are equidistantly connected to the air intake plate 201. The side of the movable rod 7 away from the limiting rod 6 is hinged to the connecting rod 202. The front and rear sides inside the outer shell 1 are movably engaged with the connecting rod 202. A sponge layer is provided on the side of the wiping block 203 near the air intake plate 201. The outer side of the wiping block 203 is made of metal material. The air intake plates 201 on both sides are inclined downward from left to right.

[0034] The movable rod 7 drives the connecting rod 202 on one side to move downward, causing the air-drawing plate 201 to tilt, allowing the wiping block 203 to slide towards the water injection component 9. The connecting rod 202 can drive the second connecting plate 909 to move downward, and the second connecting plate 909 drives the second baffle plate 910 downward, causing the water-permeable hole to open. Water can then wet the wiping block 203 through the water-permeable hole of the water pipe 901. The limiting rod 6 drives the connecting rod 202 to move upward, causing the air-drawing plate 201 to rotate in the opposite direction. The wiping block 203 slides downward under the action of gravity, and the sponge layer of the wiping block 203 can wipe the dust off the surface of the air-drawing plate 201. It is worth noting that when the air-drawing plate 201 tilts upward from the inside to the outside, it can absorb air from the upper end, and vice versa. This is existing technology and will not be elaborated further.

[0035] like Figure 2 As shown, the top of the outer shell 1 is fixedly connected to the cleaning box 8. The top of the cleaning box 8 is provided with a water inlet pipe. The side of the rotating rod 4 away from the motor 3 is connected to the bearing of the outer shell 1. A limiting plate is provided in the middle of the rotating rod 4. The left and right pull ropes 5 are wound in opposite directions. The middle of the inside of the outer shell 1 is rotatably connected to the limiting rod 6.

[0036] Clean water can be added into the cleaning box 8 through the water inlet pipe. The cleaning box 8 can store the clean water and deliver it to the water inlet pipe 901. The outer shell 1 can support and limit the rotating rod 4. The pull rope 5 is wound in opposite directions, so that the rotating rod 4 can rotate to unwrap the pull rope 5 on one side and wind the pull rope 5 on the other side. This allows the pull rope 5 to pull the limiting rod 6 to rotate, thereby changing the range of air intake of the device.

[0037] like Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, the top of the water inlet pipe 901 is fixedly connected to the cleaning box 8, and the top of the second spring 908 is fixedly connected to the cleaning box 8. Water inlets 901 have equidistant water holes on the side near the air intake assembly 2. The lengths of the first baffle 906 and the second baffle 910 are both greater than the water holes. The first baffle 906 is located above the water holes. The first limiting plate 904 and the second limiting plate 905 are both movably engaged with the water inlet pipe 901. The first limiting plate 904 includes a rectangular plate. The side of the rectangular plate near the fixing plate 902 is fixedly connected to the first spring 903. A retaining plate is equidistantly fixed to the other side of the rectangular plate. The side of the retaining plate away from the fixing plate 902 has a retaining plate that is connected to the first baffle 901. The top of the plate 906 has a slope that matches the second limiting plate 905. The side of the second limiting plate 905 away from the fixed plate 902 has an inclined surface that matches the second baffle plate 910. The front and rear ends of the bottom of the second connecting plate 909 are fixedly connected to the connecting rod 202. The positions of the first limiting plate 904, the second limiting plate 905, the first connecting plate 907 and the second connecting plate 909 are staggered. The bottom of the second connecting plate 909 is movably engaged with the water pipe 901. The outer side of the second baffle plate 910 is movably engaged with the inside of the water pipe 901. The outer side of the first baffle plate 906 is movably engaged with the inside of the water pipe 901. The outer side of the water pipe 901 is movably connected to the air venting plate 201.

[0038] The movable rod 7 drives the connecting rod 202 on one side to move downward, causing the air-drawing plate 201 to tilt, allowing the wiping block 203 to slide towards the water injection component 9. The connecting rod 202 drives the second connecting plate 909 to move downward, which in turn drives the second baffle plate 910 downward, opening the water permeable holes. Water can then wet the wiping block 203 through the water permeable holes of the water pipe 901. The limiting rod 6 drives the connecting rod 202 to move upward, causing the air-drawing plate 201 to rotate in the opposite direction. The wiping block 203 slides downward under the force of gravity, and the sponge layer of the wiping block 203 can wipe the dust off the surface of the air-drawing plate 201. The second baffle plate 910 slides downward towards the water injection component 9. The second limiting plate 905 presses and pushes the first limiting plate 904, causing the fixing plate 902 to compress. The first limiting plate 904 does not abut against the first baffle 906. The elastic force of the second spring 908 pushes the first baffle 906 downward through the first connecting plate 907, causing the first baffle 906 to block the water permeable hole. When the connecting rod 202 drives the second connecting plate 909 to move upward, the second baffle 910 moves upward and can contact the first baffle 906 and push the first baffle 906. The first baffle 906 contacts and presses against the inclined surface of the first limiting plate 904. The elastic force of the fixing plate 902 can reset the first baffle 906, allowing the device to discharge a quantitative amount of clean water.

[0039] Working principle and usage process of this invention:

[0040] First, the operator drives the rotating rod 4 to rotate via the motor 3, which can untangle the pull rope 5 on one side while entangle the pull rope 5 on the other side. This allows the pull rope 5 to pull the limiting rod 6 to tilt to one side. The limiting rod 6 can drive the wiping block 203 via the movable rod 7, so that the air intake plate 201 on one side can draw air upward for detection, and the air intake plate 201 on the other side can draw air downward for detection.

[0041] The movable rod 7 drives the connecting rod 202 on one side to move downward, causing the air intake plate 201 to tilt. This allows the wiping block 203 to slide towards the water injection component 9. The connecting rod 202 drives the second connecting plate 909 to move downward, which in turn drives the second baffle plate 910 downward, opening the water permeable holes. Water can then wet the wiping block 203 through the water permeable holes of the water intake pipe 901. The limiting rod 6 drives the connecting rod 202 to move upward, causing the air intake plate 201 to rotate in the opposite direction. The wiping block 203 slides downward under the force of gravity, and the sponge layer of the wiping block 203 can clean the dust on the surface of the air intake plate 201. The second baffle plate... 910 presses down against the second limiting plate 905, pushing the first limiting plate 904, causing the fixing plate 902 to compress. The first limiting plate 904 does not abut against the first baffle 906. The elastic force of the second spring 908 pushes the first baffle 906 downward through the first connecting plate 907, causing the first baffle 906 to block the water permeable hole. When the connecting rod 202 drives the second connecting plate 909 to move upward, the second baffle 910 moves upward and can contact the first baffle 906 and push the first baffle 906. The first baffle 906 contacts and presses against the inclined surface of the first limiting plate 904. The elastic force of the fixing plate 902 can reset the first baffle 906, completing the operation.
