Description

Technical Field

[0001] This utility model belongs to the field of environmental protection technology, and in particular relates to a dust detection device for environmental protection. Background Technology

[0002] Environmental protection generally refers to all actions taken by humankind to solve existing or potential environmental problems, coordinate the relationship between humans and the environment, and ensure the sustainable development of the economy and society. Among these actions, airborne dust is a pollutant that needs to be monitored frequently. Dust refers to airborne particulate matter within a certain size range formed when loose materials from the ground enter the ambient air under the influence of natural or human forces. Large amounts of dust are often generated at construction sites and during construction of urban municipal infrastructure. Dust monitoring devices are important tools for monitoring and controlling particulate matter in the air. Dust monitors are usually equipped with a display screen that can receive and update data from the dust monitor in real time, as well as meteorological parameters such as temperature, humidity, wind speed, and wind direction. This data is presented on the screen in the form of charts or numbers, making it convenient for the public and relevant personnel to quickly understand the current dust pollution status of the area.

[0003] The problem with existing technology is that when dust detectors perform dust detection and display data on the screen, the screen material is usually quite fragile. If the screen is not protected, it is easily hit or scratched by external objects, which can lead to screen breakage or damage. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a dust detection device for environmental protection, which has the advantage of wrapping and protecting the display screen of dust detection to prevent it from being damaged during operation. This solves the problem that when existing dust detectors perform dust detection and display data, the material of the display screen is usually relatively fragile. If the display screen is not protected, it is easily hit or scratched by external objects, which can lead to screen breakage or damage.

[0005] This utility model is implemented as follows: a dust detection device for environmental protection includes a support column, a display screen, a mounting arm, a protective cover, and a fixing structure. The support arm is fixedly connected to the top of the support column. Detectors are fixedly connected to the left and right sides of the top of the support arm. A control box is located at the bottom of the support arm and is fixedly connected to the outer surface of the support arm. The display screen is located at the bottom of the control box. The mounting arm is fixedly connected to the back of the display screen. The middle of the mounting arm is fixedly connected to the outer surface of the support column. A transparent protective cover is fitted over the outer surface of the display screen. Fixing blocks are fixedly connected to the left and right sides of the back of the protective cover. Fixing grooves are formed on the back of the two fixing blocks. Mounting grooves are formed on the left and right sides of the front of the mounting arm. The two fixing blocks are inserted into the inner walls of the two mounting grooves. Mounting rods are fixedly connected to the upper and lower sides of the inner walls of the two mounting grooves. Fixing structures are provided on the inner walls of the two mounting grooves.

[0006] As a preferred embodiment of this utility model, the fixing structure includes a movable arm, which is disposed on the back of the mounting arm. The front of the movable arm extends and penetrates into the inner wall of the mounting groove. A movable block is fixedly connected to the back of the movable arm, and a movable rod is fixedly connected to the front of the movable arm. By setting the movable arm, when the movable block is pulled backward, it can drive the movable arm to move backward, thereby driving the movable rod to move backward synchronously.

[0007] In a preferred embodiment of this invention, the movable rod is disposed on the inner wall of the mounting groove, and the movable rod is fixedly connected to the front side of the end of the movable arm that extends into the mounting groove. Two rotating arms are sleeved on the outer surface of the movable rod. By setting the movable rod, the movable rod can be driven by the movable arm to move backward in the mounting groove, thereby driving the rotation of the two rotating arms.

[0008] In a preferred embodiment of this invention, the two rotating arms are staggered to the left and right, and the ends of the two rotating arms that are far apart from each other are rotatably connected to the inner wall of the mounting groove via a rotating shaft. The surfaces of the two rotating arms are respectively provided with rotating grooves, and the inner walls of the two rotating grooves are respectively in contact with the outer surface of the moving rod. The front sides of the two rotating arms are respectively fixedly connected with push arms. By setting the rotating arms, the moving rod moves while pressing the inner walls of the two rotating grooves, thereby driving the two rotating arms to rotate in a staggered manner, thereby driving the rotation of the two push arms.

[0009] In a preferred embodiment of this utility model, the two push arms are respectively fixedly connected to the front of the two rotating arms at opposite ends. The two push arms are respectively provided with slots on the side where they are close to each other, and limit arms are respectively provided on the side where they are close to each other. By providing push arms, the two push arms can push the movement of the two limit arms respectively when rotating, and avoid the mounting rod by the slots.

[0010] In a preferred embodiment of this invention, the two limiting arms are slidably connected to the outer surface of the mounting rod at their midpoints. A limiting spring is fixedly connected to one side of the two limiting arms that are close to each other. The limiting spring is sleeved on the outer surface of the mounting rod. A limiting block is fixedly connected to the front of each of the two limiting arms. By setting the limiting arms, rotating the two pushing arms simultaneously squeezes the two limiting arms to slide closer on the surface of the mounting rod, compressing the limiting spring. The two limiting arms slide and drive the two limiting blocks closer together.

[0011] As a preferred embodiment of this utility model, the two limiting blocks are respectively fixedly connected to the opposite sides of the front of the two limiting arms, and the opposite ends of the two limiting blocks are respectively inserted into the inner wall of the fixing groove. By setting the limiting blocks, the two limiting blocks can be disengaged from the fixing groove when they move closer together, thereby releasing the fixed limiting of the fixing blocks and thus releasing the fixed connection between the protective cover and the mounting arm.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model solves the problem that existing dust detectors, when performing dust detection and displaying data on the screen, are often made of fragile materials. Without proper protection, the screen is easily damaged by impacts or scratches from external objects, leading to screen breakage or damage.

[0014] 2. This utility model, by setting up an installation arm and a protective cover, enables the installation groove and the fixing structure to work together. By fixing and limiting the fixing block inserted into the installation groove, the transparent protective cover is fixedly connected to the outer surface of the display screen to protect the display screen. This ensures that the protective cover can prevent the display screen from being impacted, scratched or worn by external objects, thereby extending the service life of the display screen.

[0020] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0021] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 4 As shown in the figure, an environmental dust detection device provided by this utility model includes a support column 1, a display screen 2, a mounting arm 3, a protective cover 4, and a fixing structure 5. The top of the support column 1 is fixedly connected to the support arm 101, and detectors 102 are fixedly connected to the left and right sides of the top of the support arm 101, respectively. A control box 103 is provided at the bottom of the support arm 101 and is fixedly connected to the outer surface of the support arm 101. The bottom of the control box 103 is provided to the display screen 2, and the back of the display screen 2 is fixedly connected to the mounting arm 3. The middle of the mounting arm 3 is fixedly connected to the outer surface of the support column 1. A transparent protective cover 4 is fitted onto the outer surface of the display screen 2. Fixing blocks 6 are fixedly connected to the left and right sides of the back of the protective cover 4, and fixing grooves 601 are respectively opened on the back of the two fixing blocks 6. Mounting grooves 7 are respectively opened on the left and right sides of the front of the mounting arm 3. The two fixing blocks 6 are respectively inserted into the inner walls of the two mounting grooves 7. Mounting rods 8 are fixedly connected to the upper and lower sides of the inner walls of the two mounting grooves 7, and fixing structures 5 are respectively provided on the inner walls of the two mounting grooves 7.

[0023] refer to Figure 2 and Figure 4 The fixed structure 5 includes a movable arm 9, which is located on the back of the mounting arm 3. The front of the movable arm 9 extends through the inner wall of the mounting groove 7. A movable block 10 is fixedly connected to the back of the movable arm 9, and a movable rod 11 is fixedly connected to the front of the movable arm 9.

[0024] The above solution is adopted: by setting up a movable arm 9, when the movable block 10 is pulled backward, it can drive the movable arm 9 to move backward, thereby driving the movable rod 11 to move backward synchronously.

[0025] refer to Figure 4The movable rod 11 is disposed on the inner wall of the mounting groove 7. The movable rod 11 is fixedly connected to the front side of the end of the movable arm 9 that extends into the mounting groove 7. Two rotating arms 12 are sleeved on the outer surface of the movable rod 11.

[0026] The above solution is adopted: by setting a movable rod 11, the movable rod 11 can be driven by the movable arm 9 to move backward in the mounting groove 7, thereby driving the rotation of the two rotating arms 12.

[0027] refer to Figure 4 Two rotating arms 12 are staggered to the left and right respectively. The ends of the two rotating arms 12 that are far apart from each other are rotatably connected to the inner wall of the mounting groove 7 through a rotating shaft. Rotating grooves 13 are respectively opened on the surface of the two rotating arms 12. The inner walls of the two rotating grooves 13 are respectively in contact with the outer surface of the moving rod 11. Pushing arms 14 are respectively fixedly connected to the front of the two rotating arms 12.

[0028] The above solution is adopted: by setting up a rotating arm 12, the moving rod 11 moves and presses the inner wall of the two rotating grooves 13, thereby driving the two rotating arms 12 to rotate in a staggered manner, thereby driving the two pushing arms 14 to rotate.

[0029] refer to Figure 4 Two push arms 14 are fixedly connected to the front of the two rotating arms 12 at opposite ends. The push arms 14 are respectively provided with slots 15 on the side that is close to each other, and limit arms 16 are respectively provided on the side that is close to each other.

[0030] The above solution is adopted: by setting the push arm 14, the two push arms 14 can push the movement of the two limit arms 16 respectively when rotating, and avoid the mounting rod 8 by the slot 15.

[0031] refer to Figure 4 The two limiting arms 16 are slidably connected to the outer surface of the mounting rod 8 in the middle. A limiting spring 17 is fixedly connected to the side of the two limiting arms 16 that are close to each other. The limiting spring 17 is sleeved on the outer surface of the mounting rod 8. A limiting block 18 is fixedly connected to the front of the two limiting arms 16 respectively.

[0032] The above solution is adopted: by setting the limiting arm 16, the two pushing arms 14 are rotated and simultaneously squeezed to make the two limiting arms 16 slide closer on the surface of the mounting rod 8, and squeeze the compression of the limiting spring 17. The two limiting arms 16 slide and drive the two limiting blocks 18 to move closer.

[0033] refer to Figure 4 Two limiting blocks 18 are fixedly connected to the two limiting arms 16 on opposite sides of their front surfaces, and the opposite ends of the two limiting blocks 18 are inserted into the inner wall of the fixing groove 601.

[0034] The above solution is adopted: by setting limit blocks 18, the two limit blocks 18 can be disengaged from the fixing groove 601 when they move closer together, thereby releasing the fixed limit on the fixing block 6 and thus releasing the fixed connection between the protective cover 4 and the mounting arm 3.

[0035] The working principle of this utility model:

[0036] In use, the protective cover 4 is placed over the front of the display screen 2, and the two fixing blocks 6 are respectively inserted into the inner walls of the two mounting slots 7. As the fixing blocks 6 move backward, they simultaneously press against the two limiting blocks 18, causing the two limiting arms 16 to slide closer. When the fixing blocks 6 are fully inserted into the mounting slots 7, the limiting spring 17 pushes the two limiting arms 16 to slide, causing the two limiting blocks 18 to move away, so that the two limiting blocks 18 are respectively inserted into the inner wall of the fixing slot 601 to fix and limit the fixing blocks 6. Simultaneously, the other fixing block 6 is also fixed by the limiting block 18, thus fixing the protective cover 4 to the front of the mounting arm 3 and protecting the display screen 2, allowing it to display the data on airborne dust detected by the control box 103 and the detector 102. The transparent protective cover 4 can protect the display screen 2 without affecting its display. For frontal protection, when it is necessary to disassemble the protective cover 4, pull the moving block 10 backward, causing it to slide the moving arm 9 backward, which in turn causes the moving rod 11 to move backward in the mounting groove 7. As the moving rod 11 moves backward, it presses against the inner walls of the two rotating grooves 13, causing the two rotating arms 12 to rotate relative to each other in a staggered manner, and causing the two pushing arms 14 to rotate respectively, and pressing the two limiting arms 16 to slide closer on the surface of the mounting rod 8. While compressing the limiting spring 17, it causes the two limiting blocks 18 to move closer to disengage from the fixing groove 601, thereby releasing the fixing limit of the fixing block 6. Repeat this method to pull the other moving block 10 to release the fixing limit of the other fixing block 6, thereby releasing the fixed connection between the protective cover 4 and the mounting arm 3. Then move the protective cover 4 backward, causing it to drive the two fixing blocks 6 to disengage from the mounting groove 7, completing the disassembly of the protective cover 4.

[0037] In summary, this environmental protection dust detection device, through the coordinated operation of the support column 1, display screen 2, mounting arm 3, protective cover 4, and fixing structure 5, solves the problem that when a dust detector performs dust detection and displays data, the material of the display screen is usually quite fragile. If the display screen is not properly protected, it is easily damaged by impacts or scratches from external objects, leading to screen breakage or damage.
