Description

Technical Field

[0001] This invention relates to the field of environmental monitoring technology, specifically to an environmental monitoring instrument. Background Technology

[0002] Environmental monitoring instruments are a general term for instruments used to monitor various parameters of indoor and outdoor environments. By measuring representative values ​​of factors affecting environmental quality, environmental quality (or pollution level) and its changing trends are determined. With the development of industrial restructuring and industrial technology upgrading, there will be a large market demand for monitoring and dedicated optimization systems for "high energy consumption, high material consumption, and high pollution" in order to meet the requirements of achieving a circular economy and energy conservation and emission reduction.

[0003] A search revealed Chinese patent CN221259916U, which discloses an environmental pollution monitoring instrument, specifically relating to the field of environmental monitoring technology. The instrument includes a placement plate with grooves, a gear rotating within the grooves, and diagonally distributed toothed plates on both sides of the gear. A movable plate is fixedly attached to one end of the toothed plates, and a fixed plate is fixedly attached to the upper surface of the movable plate. A main body is positioned between the fixed plates, and a positioning plate is located at one end of the fixed plate. The positioning plate has a sliding groove, and a movable block is fixedly attached to the side of the fixed plate closest to the positioning plate. This invention, by incorporating gears, toothed plates, a movable plate, a fixed plate, and a positioning plate, achieves convenient and rapid fixation of the main body, increasing its stability during use. The main body itself does not move during operation, thus improving its environmental monitoring effectiveness.

[0004] A search revealed Chinese patent CN215177851U, which discloses an environmental monitoring instrument device. Two sets of threaded rods have opposite ends movably mounted on a first pressure plate passing through a fixed base. Handwheels are fixedly mounted on the ends of both sets of threaded rods away from the first pressure plates. First springs are fixedly connected to the sides of the first pressure plates away from the threaded rods, and second pressure plates are fixedly connected to the other ends of the first springs. A groove is formed in the middle of the top of the placement platform, and the instrument body is placed within the groove. Placement slots are formed on the left and right side walls of the groove, and fixing blocks are fixedly mounted within each placement slot. The fixing blocks, utilizing the elasticity of the second springs, provide storage space for the instrument body. The first and second pressure plates can then be moved left and right by adjusting the threaded rods with the handwheels. This arrangement effectively secures the instrument body, preventing displacement and improving the accuracy of the test data.

[0005] Existing environmental monitoring instruments are generally placed outdoors for extended periods during use, subjecting themselves to prolonged exposure to wind and rain. This causes the surface of the instruments to accumulate a lot of dirt, leading to problems with their normal operation. Furthermore, existing environmental monitoring instruments lack necessary automatic cleaning mechanisms, resulting in high maintenance costs. Therefore, this invention designs an environmental monitoring instrument to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an environmental monitoring instrument that solves the problem of difficulty in cleaning when used outdoors in the prior art.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] An environmental monitoring instrument, comprising:

[0009] A base, on top of which a working frame is mounted, and the base and the working frame are fixedly connected by reinforcing ribs;

[0010] The top of the working frame is equipped with a working mechanism for cleaning the device. The working mechanism includes a lifting component, an adjusting component, and a cleaning component. The lifting component is located at the top of the working frame and is used to adjust the height of the cleaning component. The adjusting component is located at the top of the lifting component and is used to adjust the left and right position of the cleaning component. The cleaning component is located at the top of the adjusting component and is used to clean the surface of the working frame.

[0011] The cleaning assembly includes a movable plate, a purifier mounted on top of the movable plate, a funnel mounted on top of the purifier, a cleaning plate mounted on the bottom of the movable plate, and a cleaning pad mounted on the back of the cleaning plate.

[0012] Preferably, the lifting assembly includes a servo motor and a connecting seat mounted on the top of the working frame, a first lead screw installed between the servo motor and the connecting seat, and a coupling fixing the output shaft of the servo motor to the first lead screw. The lifting assembly also includes a fixed seat mounted on the top of the working frame, a second lead screw installed between the fixed seats, and rotating rollers installed on the front sides of both the first and second lead screws, which are connected by a belt.

[0013] Preferably, the outer rings of the first lead screw and the second lead screw are both threadedly connected to support blocks. The top of the support blocks is hinged to a rotating plate. The rotating plates are rotatably connected to each other by a pin. The top of the rotating plates is hinged to a lifting block. The top of the lifting blocks is slidably connected to a lifting frame. The working frame and the lifting frame are fixedly connected by telescopic rods. The telescopic rods are distributed in multiple matrix arrays.

[0014] Preferably, the adjustment assembly includes a stepper motor installed in the inner cavity of the lifting frame, a one-way lead screw is installed on one side of the output shaft of the stepper motor, the output shaft of the stepper motor and the one-way lead screw are fixedly connected by a coupling, a moving block is threaded to the outer ring of the one-way lead screw, and the bottom of the moving block is fixedly connected to the top of the moving plate.

[0015] First, the monitoring unit is responsible for collecting environmental data and providing a visual representation of the real-time monitoring data through an observation table. To maintain the cleanliness of the monitoring unit and instrument surfaces, a cleaning component was designed. When cleaning is required, a purifier supplies purified water to the cleaning pad, and a stepper motor drives a moving block via a unidirectional lead screw, causing the cleaning component to move left and right, thus cleaning different areas. Simultaneously, a servo motor, through a dual-lead screw synchronous drive mechanism, moves the lifting block of the lifting component up and down, thereby adjusting the height of the cleaning pad and increasing the cleaning area.

[0016] Preferably, a support plate is installed in the inner cavity of the working frame, and heat dissipation holes are provided in the inner cavity of the support plate. A monitoring body is installed on the top of the support plate, a cover plate is hinged to the back of the working frame, a movable box is installed at the bottom of the inner cavity of the working frame, a driven rack is installed on one side of the movable box, and a drive assembly is installed on one side of the working frame.

[0017] Preferably, the drive assembly includes a drive motor mounted on one side of the working frame, a drive shaft mounted on the bottom of the drive motor, a drive gear mounted on the outer ring of the drive shaft, the drive gear meshing with a driven rack, and a heat dissipation assembly also mounted in the inner cavity of the working frame.

[0019] Preferably, a limiting groove is formed at the bottom of the inner cavity of the heat sink, and a limiting block is fixedly connected to the bottom of the movable seat, with the limiting block slidably connected in the inner cavity of the limiting groove.

[0020] For heat dissipation, the heat generated by the monitoring unit during operation is regulated by a heat dissipation component. A second hydraulic rod drives a working rack to move, meshing with a connecting gear, which in turn moves a cleaning brush along the bottom of the monitoring unit for physical heat dissipation. The cleaning brush not only aids in heat dissipation but also removes dust from the bottom. The first hydraulic rod extends and retracts according to a preset program, adjusting the working range of the cleaning brush. Dust generated during heat dissipation is collected in a movable box by a design, while the drive motor, through the engagement of gears and a rack, drives the movable box to slide within the working frame, facilitating the centralized handling of dust.

[0021] Preferably, the front of the working frame is fitted with tempered glass, and an observation table is fitted on one side of the working frame.

[0022] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0023] 1. This invention integrates an automated cleaning mechanism, including a lifting component, an adjusting component, and a cleaning component, enabling automatic cleaning of the surface and key components of monitoring instruments. This design not only reduces the frequency and difficulty of manual maintenance but also significantly reduces the equipment failure rate caused by long-term dirt accumulation, thereby lowering overall maintenance costs.

[0024] 2. This invention's automatic cleaning mechanism ensures the cleanliness of the monitoring instrument's surface and key components, reducing monitoring data errors caused by dirt interference and improving data accuracy and reliability. Simultaneously, the efficient heat dissipation system ensures the monitoring unit operates under optimal conditions, guaranteeing the equipment's stability under prolonged high-load operation, further enhancing the efficiency and accuracy of environmental monitoring.

[0025] 3. In this invention, the lifting assembly adopts a dual-screw synchronous drive design, which, combined with the clever cooperation of the rotating plate, lifting block and telescopic rod, ensures the stability and accuracy of the cleaning assembly during the lifting process and effectively prevents potential damage to the equipment caused by shaking; at the same time, this design also enhances the load-bearing capacity and stability of the equipment and extends its service life.

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.

[0035] Please see Figures 1-7 In this embodiment of the invention, an environmental monitoring instrument includes:

[0036] The base 101 has a working frame 102 mounted on its top, and the base 101 and the working frame 102 are fixedly connected by a reinforcing rib 111.

[0037] The top of the working frame 102 is equipped with a working mechanism 1 for cleaning the device. The working mechanism 1 includes a lifting component 2, an adjusting component 3 and a cleaning component 4. The lifting component 2 is located at the top of the working frame 102 and is used to adjust the height of the cleaning component 4. The adjusting component 3 is located at the top of the lifting component 2 and is used to adjust the left and right position of the cleaning component 4. The cleaning component 4 is located at the top of the adjusting component 3 and is used to clean the surface of the working frame 102.

[0038] The cleaning component 4 includes a movable plate 401, a purifier 402 is installed on the top of the movable plate 401, a funnel 403 is installed on the top of the purifier 402, a cleaning plate 404 is installed on the bottom of the movable plate 401, and a cleaning pad 405 is installed on the back of the cleaning plate 404.

[0039] The lifting assembly 2 includes a servo motor 201 and a connecting seat 202 mounted on the top of the working frame 102. A first lead screw 203 is installed between the servo motor 201 and the connecting seat 202. The output shaft of the servo motor 201 is fixedly connected to the first lead screw 203 by a coupling. The lifting assembly 2 also includes a fixed seat 204 mounted on the top of the working frame 102. A second lead screw 205 is installed between the fixed seats 204. Rotary rollers 206 are installed on the front of both the first lead screw 203 and the second lead screw 205. The rotary rollers 206 are connected to each other by a belt 207.

[0040] The outer rings of the first lead screw 203 and the second lead screw 205 are both threadedly connected to support blocks 208. The top of the support blocks 208 is hinged to a rotating plate 209. The rotating plates 209 are rotatably connected to each other by a pin. The top of the rotating plates 209 is hinged to a lifting block 210. The top of the lifting block 210 is slidably connected to a lifting frame 211. The working frame 102 and the lifting frame 211 are fixedly connected by a telescopic rod 212. The telescopic rod 212 is distributed in multiple matrix arrays.

[0041] The adjustment assembly 3 includes a stepper motor 301 installed in the inner cavity of the lifting frame 211. A one-way lead screw 302 is installed on one side of the output shaft of the stepper motor 301. The output shaft of the stepper motor 301 and the one-way lead screw 302 are fixedly connected by a coupling. A moving block 303 is threadedly connected to the outer ring of the one-way lead screw 302. The bottom of the moving block 303 is fixedly connected to the top of the moving plate 401.

[0042] The working principle of this invention is as follows: After a period of use, the surface of the tempered glass 109 will accumulate a significant amount of dirt due to prolonged exposure to the natural environment. At this time, the cleaning component 4 operates. The purifier 402 purifies the water and discharges it through a water pipe to the cleaning pad 405. The stepper motor 301 starts, driving the moving block 303 horizontally via the one-way lead screw 302. Through the connection between the moving block 303 and the moving plate 401, the cleaning component 4 moves left and right to the area requiring cleaning, performing cleaning operations on different locations. The servo motor 201 is then activated. The servo motor 201 drives the first lead screw 203 to rotate via a coupling, while the first lead screw 203 simultaneously drives the second lead screw 205 to rotate synchronously via a belt 207. This design achieves synchronous drive of the two lead screws, enhancing the stability and load-bearing capacity of the lifting component 2. As the first lead screw 203 and the second lead screw 205 rotate, the support block 208 moves along the lead screws, causing the rotating plate 209 to rotate around the pivot pin, which in turn pushes the lifting block 210 to slide up or down within the lifting frame 211. The telescopic rod 212 ensures a smooth lifting process and prevents swaying. The up-and-down movement of the lifting frame 211 causes the cleaning pad 405 to move up and down, further increasing the cleaning area.

[0043] Please see Figures 1-7 In this embodiment of the invention, a support plate 103 is installed in the inner cavity of the working frame 102, and a heat dissipation hole 104 is provided in the inner cavity of the support plate 103. A monitoring body 105 is installed on the top of the support plate 103, a cover plate 106 is hinged to the back of the working frame 102, a movable box 107 is installed at the bottom of the inner cavity of the working frame 102, a driven rack 108 is installed on one side of the movable box 107, and a drive assembly 5 is installed on one side of the working frame 102.

[0044] The drive assembly 5 includes a drive motor 501 mounted on one side of the working frame 102, a drive shaft 502 mounted on the bottom of the drive motor 501, a drive gear 503 mounted on the outer ring of the drive shaft 502, the drive gear 503 meshing with the driven rack 108, and a heat dissipation assembly 6 mounted in the inner cavity of the working frame 102.

[0045] The heat dissipation assembly 6 includes a heat dissipation seat 601 installed in the inner cavity of the working frame 102. A first hydraulic rod 602 is installed on the top of the heat dissipation seat 601. A movable seat 603 is installed on one side of the first hydraulic rod 602. A second hydraulic rod 604 is installed in the inner cavity of the movable seat 603. A working rack 605 is installed on one side of the second hydraulic rod 604. A connecting shaft 606 is installed in the inner cavity of the movable seat 603. A connecting gear 607 is installed on the outer ring of the connecting shaft 606. A cleaning frame 608 is installed on one side of the connecting gear 607. A cleaning brush 609 is installed on the top of the cleaning frame 608.

[0046] A limiting groove 610 is provided at the bottom of the inner cavity of the heat sink 601, and a limiting block 611 is fixedly connected to the bottom of the movable seat 603. The limiting block 611 is slidably connected in the inner cavity of the limiting groove 610.

[0047] The working principle of this embodiment of the invention is as follows: The monitoring body 105 generates heat during operation. To maintain its normal operating temperature, the heat dissipation component 6 automatically activates. The second hydraulic rod 604 drives the working rack 605 to move. Since the working rack 605 meshes with the connecting gear 607, it drives the connecting gear 607 to rotate and the connecting shaft 606 to rotate, thereby causing the cleaning brush 609 inside the cleaning frame 608 to move at the bottom of the monitoring body 105 for physical heat dissipation. The limiting block 611 at the bottom of the moving seat 603 slides in the limiting groove 610, ensuring the stability and accuracy of the moving seat 603 during cleaning. The first hydraulic rod 602 extends and retracts according to a preset program, expanding the working range of the cleaning frame 608.

[0048] Please see Figures 1-7 In this embodiment of the invention, a tempered glass 109 is installed on the front of the working frame 102, and an observation table 110 is installed on one side of the working frame 102.

[0049] The working principle of this embodiment of the invention is as follows: the monitoring body 105 is responsible for collecting environmental data, such as temperature, humidity, and gas concentration, and transmitting the data to an external processing system. The observation table 110 provides a visual display of real-time monitoring data, allowing operators to quickly understand the current environmental conditions. The working frame 102 provides structural support and protection, while the tempered glass 109 protects the monitoring body 105, and the monitoring body 105 can be monitored through the tempered glass 109, improving safety and convenience.

[0050] Working principle: The monitoring unit 105 is responsible for collecting environmental data, such as temperature, humidity, and gas concentration, and transmitting the data to an external processing system. The observation table 110 provides a visual display of real-time monitoring data, allowing operators to quickly understand the current environmental conditions. The work frame 102 provides structural support and protection, while the tempered glass 109 protects the monitoring unit 105, and the monitoring unit 105 can be monitored through the tempered glass 109, improving safety and convenience.

[0051] After a period of use, the surface of the tempered glass 109 will accumulate a significant amount of dirt due to prolonged exposure to the natural environment. At this point, the cleaning component 4 activates. The purifier 402 purifies the water and discharges it through a pipe to the cleaning pad 405. The stepper motor 301 starts, driving the moving block 303 horizontally via the one-way lead screw 302. Through the connection between the moving block 303 and the moving plate 401, the cleaning component 4 moves left and right to the area requiring cleaning, performing cleaning operations on different locations.

[0052] The servo motor 201 is started. The servo motor 201 drives the first lead screw 203 to rotate via a coupling, while the first lead screw 203 drives the second lead screw 205 to rotate synchronously via a belt 207. This design achieves synchronous drive of the two lead screws, enhancing the stability and load-bearing capacity of the lifting assembly 2. As the first lead screw 203 and the second lead screw 205 rotate, the support block 208 moves along the lead screws, causing the rotating plate 209 to rotate around the pin, thereby pushing the lifting block 210 to slide up or down within the lifting frame 211. The telescopic rod 212 ensures smooth lifting and prevents swaying. The up-and-down movement of the lifting frame 211 causes the cleaning pad 405 to move up and down, further increasing the cleaning area.

[0053] The monitoring body 105 generates heat during operation. To maintain its normal operating temperature, the heat dissipation component 6 automatically activates. The second hydraulic rod 604 drives the working rack 605 to move. Since the working rack 605 meshes with the connecting gear 607, it drives the connecting gear 607 to rotate and the connecting shaft 606 to rotate, thereby causing the cleaning brush 609 inside the cleaning frame 608 to move at the bottom of the monitoring body 105 for physical heat dissipation. The limiting block 611 at the bottom of the moving seat 603 slides in the limiting groove 610 to ensure the stability and accuracy of the moving seat 603 during cleaning. The first hydraulic rod 602 extends and retracts according to a preset program, expanding the working range of the cleaning frame 608.

[0054] Dust is generated during the heat dissipation process. The dust passes through the through hole and enters the inner cavity of the movable box 107 for collection. The drive motor 501 drives the drive gear 503 to rotate through the drive shaft 502, which cooperates with the driven rack 108 to drive the movable box 107 to slide within the working frame 102, facilitating the centralized treatment of dust.

[0055] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
