Description

Technical Field

[0001] The invention relates to the technical field of wind and sand monitoring, and specifically provides a wind and sand instrument. Background Art

[0002] A sand meter is a device that monitors sand and dust in the air. The function of a sand meter is to help researchers understand the situation of wind and sand erosion in a region, thus providing a scientific basis for environmental protection and land management.

[0003] A new type of wind and sand meter is disclosed in the utility model with authorization announcement number CN219245304U. It adopts the method of supporting the use of two systems of laser detection and infrared camera monitoring. It uses laser diodes arranged in a vertical single row with equal spacing on the laser emitting device and applies the principle of light resistance method to convert the change of light intensity into voltage drop to display the size of sand and dust and other physical and chemical properties. It can effectively complete the monitoring of sand content in different height layers and has a wider measurement range. The infrared camera is used for image capture and real-time snapshot to obtain the sand and dust image in the instrument. The image can be analyzed and processed to further obtain relevant data of wind and sand. The two systems cooperate with each other to improve the monitoring method and ensure the accuracy of the monitoring data. In addition, in the utility model with authorization announcement number CN217043583U, an infrared camera of a sand meter is disclosed. In the utility model, when the cleaning rod moves toward the front end of the sand meter, the cleaning cotton plate on the inner wall of the cleaning rod can wipe off the dust on the surface of the camera, and when the cleaning cotton plate passes through the raised surface, the dust on the surface of the cleaning cotton plate will be dusted off. The cleaning cotton plate that has dusted off the dust will pass through the surface of the camera again and wipe the surface of the camera clean again.

[0004] Although the above two monitoring devices can both monitor outdoor wind and sand conditions, their components for monitoring wind and sand are directly exposed to the outdoors, and a large amount of sand and dust adheres to their surfaces, which will affect the monitoring effect. The "infrared camera of a wind and sand meter" cleans the sand and dust on the surface of the camera by wiping. This method not only has a poor effect in cleaning sand and dust, but also causes excessive friction between the sand and dust and the mirror surface of the camera, thereby causing scratches on the camera mirror and affecting the clarity of the image acquisition.

[0020] Furthermore, if Figures 1 to 9As shown, a protective self-cleaning mechanism is provided on the monitoring frame body 13, and the protective self-cleaning mechanism includes two baffle shells 21 symmetrically plugged into the monitoring frame body 13, and sliders 2102 are fixedly provided at the bottom of the two baffle shells 21, and twin rods 2101 are fixedly provided at positions corresponding to the sliders 2102 on the monitoring frame body 13, and the baffle shells 21 are slidably connected to the twin rods 2101 through the sliders 2102. The baffle shells 21 are made of transparent and visible material, and specifically, the baffle shells 21 are made of acrylic material; initially, one baffle shell 21 covers the outside of the light source detection device 133, and the other baffle shell 21 covers the outside of the laser emitting device 131 and the infrared camera 132. The baffle shell 21 made of acrylic material is light in weight and is easy to be installed on the monitoring frame body 13, and will not affect the normal operation of the laser emitting device 131 and the light source detection device 133. The sides of the two baffle shells 21 that are away from each other are plugged into the inner side of the monitoring frame body 13, and a sealing strip is provided at the plug-in position. Subsequent staff can easily slide open the two baffle shells 21 to facilitate the inspection or replacement of the laser emitting device 131, the light source detection device 133 and the infrared camera 132, thereby ensuring the convenience of operation during maintenance work. At the same time, the sealing strip can ensure the tightness of the baffle shell 21 and the inner side of the monitoring frame body 13 to prevent external dust from entering the baffle shell 21. The monitoring frame body 13 is symmetrically fixedly connected to two cavity plates 22, and the two cavity plates 22 are provided with air outlet nozzles on one side close to the baffle shell 21. After the baffle shell 21 is plugged into the monitoring frame body 13, the air outlet nozzles on the cavity plates 22 face the adjacent baffle shell 21, and a concave tube 23 is connected between the two cavity plates 22. A box body 24 is fixedly connected to one side of the monitoring frame body 13, and a piston cylinder 27 is fixedly connected to the monitoring frame body 13. The piston cylinder 27 is located below the box body 24. The inner center of the piston cylinder 27 is rotatably connected to a reciprocating screw 28, and a piston disk 29 is threadedly connected to the reciprocating screw 28. The piston disk 29 is slidably connected to the piston cylinder 27. The rotation of the reciprocating screw 28 can drive the piston disk 29 to move up and down. The upper end of the reciprocating screw 28 passes through the piston cylinder 27 and extends to the inside of the box body 24. A motor 25 is installed on the box body 24. The box body 24 is composed of a rectangular shell at the bottom and a shell cover at the top, and the rectangular shell is fixedly arranged on the monitoring frame body 13, and the shell cover is tightly plugged into the rectangular shell. Specifically, the motor 25 is fixedly installed on the shell cover, and its output shaft passes through the shell cover downward. The shell 26 is detachably installed on the shell cover of the box body 24. The shell 26 is made of aluminum alloy, and a heat dissipation grille is evenly arranged on the side of the shell 26 close to the monitoring frame body 13. The shell 26 covers the outside of the motor 25 and is fastened to the shell cover in the box body 24 by screws. The shell 26 is used to protect the motor 25, and the heat dissipation grille on the side of the shell 26 close to the monitoring frame body 13 can reduce the entry of wind and sand, and at the same time provide heat dissipation for the motor 25.The output shaft below the motor 25 extends to the interior of the box body 24, and the reciprocating screw rod 28 is fixedly connected to a synchronous wheel 210 at one end inside the box body 24. The synchronous wheel 210 and the output shaft of the motor 25 are plug-in fit. The bottom of the piston cylinder 27 is connected to an air supply pipe 271, and the end of the air supply pipe 271 away from the piston cylinder 27 is connected to the adjacent cavity plate 22. A one-way air outlet valve is installed at the portion where the air supply pipe 271 is connected to the piston cylinder 27, and an air inlet pipe 272 is connected to the side of the bottom of the piston cylinder 27 away from the air supply pipe 271. A one-way air inlet valve is installed at the portion where the air inlet pipe 272 is connected to the piston cylinder 27, and a filter screen 273 is clamped on the side of the air inlet pipe 272 away from the piston cylinder 27.

[0021] like Figure 6 As shown, the monitoring frame body 13 is rotatably connected with a belt shaft cam 211, which is composed of a rod body and a cam. The rod body is rotatably connected to the monitoring frame body 13, and the belt shaft cam 211 is located on the side of the monitoring frame body 13 away from the piston cylinder 27. The upper end of the rod body of the belt shaft cam 211 is fixedly connected with a synchronous wheel 212, and a synchronous belt 213 is connected between the synchronous wheel 212 and the synchronous wheel 1 210. The position corresponding to the monitoring frame body 13 and the synchronous belt 213 is provided with a hole for the synchronous belt 213 to pass through. Specifically, a box body 241 is provided at a position corresponding to the monitoring frame main body 13 and the synchronous wheel 212. The box body 241 includes a rectangular shell 2 and a shell cover 2. The rectangular shell 2 is fixedly connected to the monitoring frame main body 13. The shell cover 2 is plugged into the rectangular shell 2. The upper end of the rod body with the shaft cam 211 passes through the rectangular shell 2. The synchronous wheel 212 is located inside the box body 241. The box body 24 and the box body 241 are used to protect the synchronous wheel 1 210, the synchronous wheel 212 and the synchronous belt 213 to ensure stable transmission. Four short rods 216 are evenly fixedly connected to the side of the monitoring frame main body 13 away from the piston cylinder 27. The four short rods 216 are all sleeved with springs 1 217. The four short rods 216 are slidably connected to the rectangular frame 214. One end of the spring 1 217 is fixedly connected to the rectangular frame 214, and the other end is fixedly connected to the outer wall of the adjacent short rod 216. A plurality of abutment shafts 215 are evenly and fixedly connected to one side of the rectangular frame 214 corresponding to the retaining shell 21. The abutment shafts 215 are made of rubber. Abutment plates 218 are fixedly connected to the rectangular frame 214. The abutment plates 218 are arranged corresponding to the position of the cam in the shaft cam 211. The abutment plates 218 are located on the rotation path of the cam.

[0022] During use: first, the staff will firmly install the base 1 on the ground for outdoor wind and sand monitoring, and then start the laser emitting device 131, the infrared camera 132, and the light source detection device 133 to start operation. When wind blows outdoors, the windward plate 14 will drive the monitoring frame body 13 and the moving shaft 12 to rotate with the fixed shaft 11 as the fulcrum, and as the windward plate 14 rotates, the side of the monitoring frame body 13 where the piston cylinder 27 is installed can always be in the windward direction of the wind and sand, so that the wind and sand pass through the monitoring frame body 13 and pass between the laser emitting device 131 and the light source detection device 133. The cooperation of the two and the infrared camera 132 is used to monitor the sand content in the wind and the wind and sand picture in real time, and then the monitored data is transmitted to the data receiving end of the staff through the wireless communication module, so as to achieve real-time monitoring effect of wind and sand.

[0023] At the same time, by starting the motor 25, the output shaft of the motor 25 drives the reciprocating screw 28 to rotate. As the reciprocating screw 28 continues to rotate, it will drive the piston plate 29 to continuously move back and forth up and down inside the piston cylinder 27. When the piston plate 29 moves from bottom to top inside the piston cylinder 27, the one-way air intake valve on the intake pipe 272 opens. At this time, the interior of the piston cylinder 27 is connected to the outside through the intake pipe 272, and cooperates with the piston plate 29 to move upward inside the piston cylinder 27 to suck external air into the interior of the piston cylinder 27. During the process of external air being sucked into the piston cylinder 27, the filter screen 273 can intercept sand and dust in the air, thereby reducing the sand and dust in the inhaled air. When the piston disc 29 moves downward inside the piston cylinder 27, the one-way air inlet valve is closed and the one-way air outlet valve is opened. At this time, the piston cylinder 27 is connected to the air supply pipe 271, so that the air inside the piston cylinder 27 is discharged outward, and the air is sent into the cavity plate 22 along the air supply pipe 271. The air is blown out in the direction close to the baffle shell 21 through the air outlet nozzle on the cavity plate 22, so as to blow off the sand and dust attached to the surface of the baffle shell 21. As the reciprocating screw 28 continues to rotate, the piston disc 29 will continue to repeatedly pump and blow air, so as to blow the outer surfaces of the two baffle shells 21. Therefore, the two baffle shells 21 are used to block the outside of the laser emitting device 131, the infrared camera 132, and the light source detection device 133, so as to avoid a large amount of sand and dust from being attached to the surface of the monitoring components in the sand meter without affecting the monitoring effect, thereby ensuring the monitoring effect of the sand meter on the wind and sand, and also ensuring the safety of the monitoring components in the sand meter when used outdoors. In addition, the outer surfaces of the two baffle shells 21 are blown in real time in cooperation with the two cavity plates 22 to further reduce the dust adhering to the baffle shells 21. Compared with the wiping method used in the prior art to reduce the dust, the blowing method will not affect the normal monitoring of the laser emitting device 131 and the light source detection device 133 and the image acquisition of the infrared camera 132, and can reduce the friction between the dust and the attached surface and reduce scratches, thereby ensuring the effectiveness of wind and sand monitoring.

[0024] At the same time, as the reciprocating screw rod 28 rotates, the belt shaft cam 211 can be driven to rotate synchronously through the transmission of the synchronous wheel 1 210, the synchronous wheel 212, and the synchronous belt 213. After the belt shaft cam 211 rotates, the cam in the belt shaft cam 211 will conflict with the abutment plate 218, and push the rectangular frame 214 to move in the direction away from the baffle shell 21, and stretch the spring 1 217. When the cam is not in contact with the abutment plate 218, the rebound force of the spring 1 217 makes the abutment shaft 215 hit the outer surface of the baffle shell 21. Therefore, as the belt shaft cam 211 continues to rotate, the cam and the abutment plate 218 cooperate to intermittently drive the abutment shaft 215 to hit the outer surface of the baffle shell 21, and the abutment shaft 215 is used to knock on the surface of the baffle shell 21 to shake off the sand and dust, thereby accelerating the speed at which the sand and dust fall from the outer surface of the baffle shell 21, thereby further ensuring the light transmission effect of the baffle shell 21, so as to better perform outdoor wind and sand monitoring operations.

[0025] Embodiment 2: Figure 1 , Figures 8 to 10 As shown, the above-mentioned sand meter also includes a matching processing component, which includes a perforated plate 31 fixedly connected to the outer surface of the piston cylinder 27, and a vertical plate 32 is slidably provided on the side of the perforated plate 31 away from the piston cylinder 27. The perforated plate 31 is provided with a rectangular through-hole, and the vertical plate 32 slides in the rectangular through-hole. A spring 2 34 is connected between the bottom surface of the perforated plate 31 and the vertical plate 32, and a contact plate 33 is fixedly connected to the part of the reciprocating screw 28 located above the piston cylinder 27. The contact plate 33 is arranged below the box body 24. The end of the vertical plate 32 close to the contact plate 33 is fixedly connected to a contact rod 321, and the contact rod 321 is located on the rotation path of the contact plate 33. Specifically, the contact plate 33 is provided with a triangular extrusion portion, and the contact rod 321 is located on the rotation path of the extrusion portion. A brush plate 35 is fixedly connected to one end of the vertical plate 32 close to the filter screen 273, and the brush plate 35 can fit with the surface of the side of the filter screen 273 away from the air inlet pipe 272 after moving down.

[0026] During use: in order to reduce the dust adhering to the surface of the filter screen 273, when the reciprocating screw 28 rotates, it will also drive the resisting plate 33 to rotate synchronously. As the resisting plate 33 rotates, its triangular extrusion portion will be prompted to contact the resisting rod 321, thereby prompting the resisting rod 321 and the vertical plate 32 to move vertically downward along the rectangular through-hole on the perforated plate 31, and at the same time stretching the spring 2 34. As the vertical plate 32 moves downward, it will drive the brush plate 35 to move downward synchronously along the surface of the filter screen 273; and when the extrusion portion of the resisting plate 33 does not contact the resisting rod 321, under the action of the rebound force of the spring 2 34, the vertical plate 32, the resisting rod 321, and the brush plate 35 are driven to move upward synchronously. Therefore, by using the brush plate 35 to move back and forth up and down along the surface of the filter 273, the dust adhering to the surface of the filter 273 can be scraped off, reducing the dust adhering to the surface of the filter 273, avoiding affecting the piston cylinder 27 from inhaling air from the intake pipe 272, and avoiding the dust from being inhaled into the piston cylinder 27.

[0027] Embodiment 3: Figure 1 , Fig.11 , Fig.12 As shown, the above-mentioned sand meter also includes a sand collecting mechanism, which includes a cylinder 41 fixedly connected to the outer ring surface of the fixed shaft 11, a plurality of annular partition units 42 are arranged in the cylinder 41, a sand discharge port is arranged at a position corresponding to each partition unit 42 at the bottom of the cylinder 41, a sealing plug 47 is threadedly connected to the sand discharge port, a rotary disk 43 is rotatably connected to the top of the cylinder 41, and the rotary disk 43 is rotatably connected to the cylinder 41, and the above-mentioned cylinder 41 and the rotary disk 43 are both made of acrylic transparent material, so that the detection personnel can intuitively see the amount of sand collected in the partition unit 42. A plurality of vertical pipes 44 are fixedly connected to the outer ring surface of the moving shaft 12, the number of vertical pipes 44 is the same as the number of partition units 42, the positions of the plurality of vertical pipes 44 are arranged one by one corresponding to the positions of the plurality of partition units 42, the lower end of the vertical pipe 44 passes through the rotary disk 43 and extends to the inside of the corresponding partition unit 42, and specifically, a through hole for each vertical pipe 44 to pass through is opened on the rotary disk 43. Each vertical pipe 44 is connected to an air inlet cavity plate 45 at one end away from the rotating disk 43. The height positions of the multiple air inlet cavity plates 45 are distributed in a stepped manner. The side of the air inlet cavity plate 45 close to the monitoring frame body 13 is expanded to allow wind and sand to enter the air inlet cavity plate 45. The inner bottom of the air inlet cavity plate 45 is closed downward to better collect wind and sand, and the air inlet cavity plates 45 are all located within the windward area of ​​the monitoring frame body 13. A filter plate 46 is clamped on the side of the air inlet cavity plate 45 away from the monitoring frame body 13.

[0028] When in use: When the wind and sand pass through the monitoring frame body 13, the wind and sand will enter the interior of each air inlet cavity plate 45 distributed in a stepped manner, and the filter plate 46 will intercept the sand and dust, causing the sand and dust to fall into the air inlet cavity plate 45, and collect the sand and dust through the closing part of the air inlet cavity plate 45. Under the action of gravity, the sand and dust fall into the vertical pipe 44, and fall into the corresponding partition unit 42 through each vertical pipe 44, thereby realizing real-time collection of sand and dust. Since each vertical pipe 44 passes through the rotating disk 43, and the rotating disk 43 is rotatably connected to the cylinder 41, when the wind and sand blow toward the windward plate 14 and drive the monitoring frame body 13 and the moving shaft 12 to rotate, each vertical pipe 44 will also drive the rotating disk 43 to rotate synchronously, so as not to affect the normal rotation of the monitoring frame body 13. Therefore, by utilizing a plurality of air inlet chamber plates 45 that are distributed in a stepped manner at different heights, it is possible to collect sand and dust in the wind at different heights and collect them into independent partition units 42 through vertical pipes 44, thereby reducing the adhesion of sand and dust to the air inlet chamber plates 45 and avoiding excessive sand and dust load on the monitoring frame body 13 that affects the rotation effect of the monitoring frame body 13, so that the monitoring frame body 13 can rotate freely to monitor the wind and sand in all directions.

[0029] At the same time, the sand and dust will be collected into the interior of the partition unit 42 through the vertical pipe 44, and the partition unit 42 is located on the fixed axis 11, so as the sand and dust in the partition unit 42 is collected more, the weight of the lower plate of the wind sand instrument will be increased, thereby ensuring its stability in outdoor wind sand monitoring operations. In addition, when the staff conducts outdoor field wind sand monitoring, by observing the amount of sand and dust collected in the cylinder 41 of transparent material, and then turning to open each sealing plug 47 in turn, the sand and dust inside each partition unit 42 is discharged into different external collection containers, so as to provide the staff with sand content data in the wind at different heights, so as to facilitate the staff to further analyze the wind sand conditions in the area.
