[0016] 1.

[0018] 3. The lifting assembly of the present invention realizes stepless adjustment of the shell height through screw transmission, expanding the vertical space monitoring dimension. In the process of lifting the shell, the wave guide groove will make the brush roller brush back and forth on the outside of the filter cover for cleaning. At the same time, it can also use the gear set to rotate, so as to mechanically remove stubborn attachments on the filter cover. Combined with the wind power at the air outlet to assist in cleaning, a multi-stage dust removal guarantee is formed to ensure stable filtering efficiency under long-term monitoring conditions.

DETAILED DESCRIPTION

[0026] See also Figures 1 to 4 The present invention provides a technical solution: an environmental sensing device for multi-probe environmental monitoring, comprising a fixing base 1 and a protective component 6, a lifting component 2 is arranged in the middle of the fixing base 1, and a shell 3 is arranged on the outer side of the middle of the lifting component 2, the lifting component 2 includes an adjusting motor 201, an adjusting motor 201 is fixed to the bottom surface of the middle of the fixing base 1, and the output shaft of the adjusting motor 201 is connected to a screw 202, the outer side of the screw 202 is threadedly connected to a lifting base 203, and the two sides of the lifting base 203 are slidably connected to side plates 204, and the side plates 204 are fixedly connected to the fixing base 1, an air inlet 4 is opened on one side of the shell 3, and an air outlet 5 is opened on the other side of the shell 3, the protective component 6 is arranged on the outside of the shell 3, and the protective Component 6 includes a servo motor 601. The servo motor 601 is placed outside the housing 3, and a driving gear 602 is fixed to the end of the output shaft of the servo motor 601. A driven gear 603 is meshed on one side of the driving gear 602, and a fan shaft 604 is placed inside the driven gear 603. A support plate 605 is rotatably connected to the outer side of the middle part of the fan shaft 604. A synchronous gear 606 is placed in the middle of the output shaft of the servo motor 601, and a transmission gear 607 is meshed on one side of the synchronous gear 606. A drive ring gear 608 is meshed on one side of the transmission gear 607, and a filter cover 609 is fixed to the outer circumference of the drive ring gear 608. The support plate 605 is fixedly connected to the housing 3, and the filter cover 609 is rotatably connected to the housing 3.

[0027] The specific operation is as follows. When monitoring the air at different heights, it is only necessary to start the adjustment motor 201 so that it drives the lifting seat 203 to slide inside the side plate 204 through the screw 202, and the height of the shell 3 can be adjusted, thereby increasing the use range of the environmental sensing device. When monitoring the air in the environment, the servo motor 601 will drive the fan shaft 604 to rotate through the driving gear 602 and the driven gear 603, so that the external air can be sucked into the shell 3 and transported to the sensor. The contact efficiency between the air and the sensor is improved through forced convection, and the local concentration deviation caused by air stagnation around the sensor is avoided, thereby improving the monitoring effect of the sensor. At the same time, when the air enters from the air inlet 4, the filter cover 609 will filter the air to prevent dust and impurities from contaminating the sensor, and When the servo motor 601 drives the fan shaft 604 to rotate, it will also drive the filter cover 609 to rotate through the synchronous gear 606, the transmission gear 607 and the drive ring gear 608, thereby automatically changing the filtering position of the filter cover 609 to avoid continuous use of a single position of the filter cover 609, which will cause excessive impurities and dust to adhere to the position and cause blockage. At the same time, since the air flow will be discharged from the air outlet 5, during the continuous rotation of the filter cover 609, when the part where the dust and impurities are attached moves to the air outlet 5, the air flow inside the shell 3 will blow towards the filter cover 609, and the filter cover 609 can be back-blown and cleaned from the inside, thereby preventing impurities and dust from continuing to adhere to the filter cover 609, so that the environmental sensing device has a self-cleaning function, making maintenance more convenient.

[0028] See also Figure 2 、 Figure 3 and Figure 5 , a uniform distribution component 7 is provided inside the shell 3, and the uniform distribution component 7 includes a guide baffle 701, a guide baffle 701 is arranged on the upper end of the interior of the shell 3, and a guide plate 702 is fixed to one side of the guide baffle 701, a stirring rod 703 is fixed to one end of the fan shaft 604, and a planetary gear 704 is arranged on the end of the stirring rod 703, and a synchronous ring gear 705 is engaged with the bottom of the planetary gear 704, and the synchronous ring gear 705 is rotatably connected to the shell 3, a perforated plate 706 is fixed to the middle of the shell 3, and a partition 707 is arranged at the bottom of the perforated plate 706, and a sensor probe 708 is arranged between the partitions 707, and an exhaust pipe 709 is connected to one side of the shell 3;

[0029] The specific operation is as follows: when the fan shaft 604 rotates to suck the external air into the shell 3, the guide plate 702 will guide the air. Since the opening formed at the tail of the guide plate 702 is small, the air flow velocity can be increased, so that the air flow is quickly blown to the inside of the guide baffle 701. At this time, since the inner side of the guide baffle 701 is in an arc shape, the air flow flows in a spiral shape, which can preliminarily mix the internal air. At the same time, when the fan shaft 604 rotates, it will also drive the stirring rod 703 to rotate, and through the planetary gear 704 and the synchronous ring gear 705, the other stirring rods 703 rotate synchronously, further disturbing the airflow and avoiding the internal air components from being separated. The uneven distribution of air affects the detection effect of multiple sensor probes 708, and the mixed air will flow to the sensor probe 708 through the orifice plate 706, so that different types of sensor probes 708, such as CO, NO2, SO2, O2, and CH4 sensors, can be used to monitor the air. The partition frame 707 is used to separate multiple different types of sensor probes 708 to reduce the mutual influence between different types of sensor probes 708, thereby improving the detection accuracy. After that, the airflow will be transported to the air outlet 5 through the exhaust pipe 709 and then discharged to the outside of the shell 3. Therefore, during the monitoring process, the functions of mixing and dividing the samples are automatically realized.

[0030] See also Figure 1 and Figure 6 , a cleaning assembly 8 is provided on the top of the shell 3, and the cleaning assembly 8 includes a guide groove 801, a guide groove 801 is opened on the outer side of the side plate 204, and the guide groove 801 is wavy, and a sliding column 802 is slidably connected to the inside of the guide groove 801, a rotating sleeve 803 is fixed to one end of the sliding column 802, and the bottom of the rotating sleeve 803 is rotatably connected to a limiting ring 804, the limiting ring 804 is fixedly connected to the shell 3, and the transmission gear 607 is rotatably connected to the shell 3, a connecting plate 805 is fixed to the outer circumference of the limiting ring 804, and the end of the connecting plate 805 is rotatably connected to a brush roller 806, a driving gear 807 is arranged on the outer side of the upper part of the brush roller 806, and a reversing gear 808 is meshed on one side of the driving gear 807, the reversing gear 808 is rotatably connected to the connecting plate 805, and a rack 809 is meshed on one side of the reversing gear 808, the rack 809 is arc-shaped, and the rack 809 is fixed to the shell 3;

[0031] The specific operation is as follows: during the lifting process of the shell 3, the limiting ring 804 will also drive the rotating sleeve 803 to rise and fall synchronously, so that the sliding column 802 slides inside the guide groove 801. At this time, since the guide groove 801 is wavy, the rotating sleeve 803 can be rotated back and forth under the limit of the limiting ring 804, thereby controlling the connecting plate 805 to make the brush roller 806 brush the outside of the filter cover 609 to clean it, which can sweep away firmly adhered impurities. At the same time, the brush roller 806 is located at the air outlet 5, so the air flow can also be used to blow air to the outside of the brush roller 806 to clean it, so as to avoid the dust on the outside of the brush roller 806 from continuing to adhere to the dust and affecting the effect of subsequent cleaning. At the same time, during the brushing and cleaning process, the brush roller 806 will also drive the reversing gear 808 to roll on the rack 809. Therefore, during the brushing and cleaning process, the driving gear 807 will also drive the brush roller 806 to rotate, further enhancing the cleaning effect of the brush roller 806.

[0032] In summary, when the multi-probe environmental monitoring environmental sensing device is used, the servo motor 601 first drives the fan shaft 604 to rotate through the driving gear 602 and the driven gear 603, so that the external air can be sucked into the housing 3, and the filter cover 609 will filter the air to prevent dust and impurities from contaminating the sensor;

[0033] Next, the guide plate 702 will guide the air. Since the opening formed at the tail of the guide plate 702 is small, the air flow velocity can be increased, so that the air flow is quickly blown to the inside of the guide baffle 701. At this time, since the inner side of the guide baffle 701 is in an arc shape, the air flow is spirally flowing, which can preliminarily mix the internal air. At the same time, when the fan shaft 604 rotates, it will also drive the stirring rod 703 to rotate, and through the planetary gear 704 and the synchronous gear ring 705, the other stirring rods 703 rotate synchronously, further disturbing the air flow to avoid the internal air from being disturbed. The uneven distribution of components affects the detection effect of multiple sensor probes 708, and the mixed air will flow to the sensor probe 708 through the orifice plate 706, so that different types of sensor probes 708, such as CO, NO2, SO2, O2, and CH4 sensors, can be used to monitor the air. The multiple different types of sensor probes 708 are separated by the partition 707 to reduce the mutual influence between the different types of sensor probes 708. The air flow will then be transported to the outlet 5 through the exhaust pipe 709 and then discharged outside the shell 3.

[0034] Then, the servo motor 601 will drive the filter cover 609 to rotate through the synchronous gear 606, the transmission gear 607 and the drive ring gear 608, thereby automatically changing the filtering position of the filter cover 609, thereby preventing the filter cover 609 from being continuously used in a single position, which may cause excessive impurities and dust to adhere to the position and cause blockage. At the same time, since the air flow will be discharged from the air outlet 5, during the continuous rotation of the filter cover 609, when the part where the dust and impurities are attached moves to the air outlet 5, the air flow inside the housing 3 will blow towards the filter cover 609, and the filter cover 609 can be back-blown from the inside to clean it, thereby preventing impurities and dust from continuing to adhere to the filter cover 609.

[0035] Finally, when monitoring the air at different heights, it is only necessary to start the regulating motor 201 so that the screw 202 drives the lifting seat 203 to slide inside the side plate 204, and the height of the shell 3 can be adjusted, thereby increasing the use range of the environmental sensing device. In addition, during the lifting process of the shell 3, the limiting ring 804 will also drive the rotating sleeve 803 to rise and fall synchronously, so that the slide column 802 slides inside the guide groove 801. At this time, since the guide groove 801 is wavy, the rotating sleeve 803 can be reciprocated under the limit of the limiting ring 804, thereby controlling the connecting plate 805 to make the brush The roller 806 can be used to brush the outside of the filter cover 609 to clean it, so that firmly adhering impurities can be swept off. At the same time, the brush roller 806 is located at the air outlet 5, so the air flow can also be used to blow air to clean the outside of the brush roller 806, avoiding the continuous adhesion of dust on the outside of the brush roller 806 and affecting the effect of subsequent cleaning. At the same time, during the brushing cleaning process, the brush roller 806 will also drive the reversing gear 808 to roll on the rack 809. Therefore, during the brushing cleaning process, the driving gear 807 will also drive the brush roller 806 to rotate, further enhancing the cleaning effect of the brush roller 806.
