Description

Technical Field

[0001] The utility model belongs to the technical field of dust monitoring equipment, in particular to an air dust monitoring device for environmental detection. Background Art

[0002] Air dust monitoring in environmental testing refers to the qualitative and quantitative monitoring and assessment of suspended particulate matter in the atmosphere. Suspended particulate matter includes visible particles, microparticles, dust, etc., which mainly come from industrial emissions, traffic exhaust, coal burning, construction, etc. These particulate matter are not only harmful to human health, but also have a negative impact on the environment and ecosystem.

[0003] At present, in the actual application of existing dust monitoring equipment, it is found that dust in the air is often directly adsorbed on the surface of the filter, which needs to be cleaned or replaced regularly to maintain long-term performance. This undoubtedly wastes a lot of time. In addition, the installation position of the equipment is generally high, making cleaning and replacement operations more difficult, which is not conducive to the stable use of dust monitoring.

[0004] In order to solve the above problems, this application proposes an air dust monitoring device for environmental detection. Utility Model Content

[0005] The purpose of the utility model is to provide an air dust monitoring device for environmental detection, which solves the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is an air dust monitoring device for environmental detection, comprising: a monitor and a convex tube at its front end; a first filter screen and a second filter screen are provided inside the front end of the convex tube, and a windmill is provided above the first filter screen to drive the first filter screen to rotate, so that a scraping motion is formed between the first filter screen and the second filter screen to cause dust and impurities to fall off, so as to maintain long-term filtering performance; a first ring frame and a second ring frame are rotatably installed inside the front end of the convex tube, on which the second filter screen and the first filter screen are installed respectively; a connecting rod is provided at the rear of the first filter screen, which is connected to an arc-shaped frame near the rear area inside the convex tube, and a cleaning pad is provided on the inner side of the arc-shaped frame for cleaning the sensing probe of the monitor; a side groove is provided at the bottom of the convex tube, and bristles are provided inside it, so that dust and impurities are discharged downward under the movement of the dial plate below the arc-shaped frame.

[0008] Furthermore, a guide slope is provided on the inner side of the second ring frame for guiding impurities falling off from the inside of the first filter screen outwards.

[0009] Furthermore, a counterweight ball is provided in front of the shift plate, which is used to generate inertial power when the arc frame rotates to cause it to rotate repeatedly.

[0010] Further, a convex block is provided on one side of the second ring frame and is rotatably installed inside a groove on the opposite surface of the first ring frame.

[0011] Further, a ball is installed inside the convex block to reduce the frictional resistance between the second ring frame and the first ring frame.

[0012] Further, a protruding convex plate is provided on the outer side in front of the second ring frame and is located inside a groove behind the front end cover plate of the convex tube.

[0013] Further, a convex ring is provided at the lower end of the windmill, and rotational power is transmitted through the engagement of the convex teeth on its outer side with the convex teeth on the inner side of the convex plate.

[0014] The utility model has the following beneficial effects:

[0015] Through the cooperation of the first ring frame and the second ring frame and the reduction of frictional resistance by the balls, the utility model can easily drive the second ring frame to rotate when there is wind outside by using the windmill, so that the first filter screen rotates and cooperates with the second filter screen to form a scraping treatment to remove residual impurities on the surface, ensuring the filtering performance during long-term use, and achieving the effect of maintaining long-term use performance without manual regular cleaning and replacement;

[0016] In addition, during the rotation of the first filter screen, it will also drive the cleaning pad to wipe the surface of the induction probe, forming a double internal and external cleaning effect to prevent dust from adsorbing on the probe and affecting the subsequent monitoring effect, ensuring the sensitivity of the probe during monitoring operations, and at the same time using the flipping of the dial to drive the bristles, so that the dust is automatically discharged downward.

[0017] Of course, it is not necessary for any product implementing the utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or positional relationship are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0028] Please refer to Figure 1-5 As shown, the present utility model is an air dust monitoring device for environmental detection, including: a monitor 1 and a convex tube 2 at its front end; inside the front end of the convex tube 2, there are a first filter screen 3 and a second filter screen 10 which are layered front and back. Above the first filter screen 3, there is a windmill 5 that drives the first filter screen 3 to rotate, so that a scraping motion is formed between the first filter screen 3 and the second filter screen 10 to promote the shedding of dust and impurities, so as to maintain the filtering performance for a long time. Inside the front end of the convex tube 2, a first ring frame 6 and a second ring frame 7 are rotatably installed, and the second filter screen 10 and the first filter screen 3 are installed respectively;

[0029] Behind the first filter screen 3, there is a connecting rod 9, which is connected to an arc-shaped frame 8 in the rear area near the inside of the convex tube 2. Inside the arc-shaped frame 8, there is a cleaning pad 15 for cleaning the induction probe of the monitor 1;

[0030] A side groove 13 is provided at the bottom of the convex tube 2, and a brush 14 is provided inside the side groove 13. The dust and impurities are discharged downwards by the movement of the paddle 11 below the arc frame 8.

[0031] This embodiment provides a dust monitoring device that does not require manual regular cleaning. The windmill 5 is combined with external wind force to drive the first filter 3 to rotate, forming scraping between the first filter 3 and the second filter 10, so that dust and impurities in the mesh are automatically removed. In addition, the cleaning pad 15 can be driven to rotate to achieve the effect of real-time cleaning of the sensing probe.

[0032] A guide slope 4 is provided on the inner side of the second ring frame 7 for guiding impurities fallen from the inside of the first filter screen 3 outwards to prevent the fallen impurities from still accumulating and affecting the use effect.

[0033] Among them, a counterweight ball 12 is provided in front of the paddle 11, which is used to generate inertial power when the arc frame 8 rotates to cause it to rotate repeatedly, thereby achieving multiple cleaning effects, and at the same time driving the first filter 3 to rotate in the reverse direction to promote the discharge of dust and impurities.

[0034] A protrusion 16 is provided on one side of the second ring frame 7 and is rotatably mounted in a groove on the opposite side of the first ring frame 6 .

[0035] The balls 17 are installed inside the protrusion 16 and are distributed on the outer side surface and the inner and outer ring sides of the protrusion 16 to reduce the friction resistance between the second ring frame 7 and the first ring frame 6.

[0036] A protruding convex plate 18 is provided on the front outer side of the second ring frame 7 and is located inside the groove behind the front end cover of the convex tube 2 .

[0037] The lower end of the windmill 5 is provided with a convex ring 19 , and the convex teeth 20 on the outer side of the convex ring 19 come into contact with the convex teeth 20 on the inner side of the convex plate 18 to transmit rotational power.

[0038] It can be understood that the dust monitoring equipment of the present invention does not require manual regular cleaning. It uses the windmill 5 combined with external wind force to drive the first filter 3 to rotate, forming scraping between the first filter 3 and the second filter 10, so that the dust and impurities in the mesh automatically fall off. In addition, it can also drive the cleaning pad 15 to rotate, thereby achieving the effect of real-time cleaning of the sensing probe.

[0039] A specific application of the operating process of this embodiment is as follows: when in use, the windmill 5 is first driven to rotate by the external wind force, and then the power is transmitted to the second ring frame 7. Combined with the friction resistance reduced by the ball bearing 17, the second ring frame 7 can be easily driven to rotate, so that the first filter 3 forms a scraping resistance on the surface of the second filter 10 to remove dust and impurities inside the mesh and make them fall off automatically, thereby ensuring long-term performance without manual regular cleaning and replacement; in addition, the rotation of the first filter 3 can also drive the arc frame 8 to rotate, and clean the surface of the probe through the cleaning pad 15 on its inner side to prevent a large amount of impurities from accumulating and affecting the accuracy of the monitoring data; finally, the counterweight ball 12 can form a swinging effect on the paddle plate 11 when the arc frame 8 rotates, so as to reversely promote the number of rotations of the cleaning pad 15, and at the same time drive the paddle plate 11 to poke the bristles 14 so that impurities are discharged downward.
