Description

Technical Field

[0001] The utility model relates to an air quality monitoring device, belonging to the technical field of environmental monitoring. Background Art

[0002] Most of the existing air quality monitoring equipment is of fixed design. They usually rely on fans to draw air into the equipment so that the air comes into contact with the monitoring module to analyze and evaluate the air quality. However, this type of fixed monitoring equipment has a series of problems and limitations in use.

[0003] First, the fans in fixed monitoring equipment usually need to run continuously during the monitoring process. This uninterrupted operation mode leads to a large amount of energy consumption, especially in the case of long-term monitoring or limited energy supply. This problem becomes particularly prominent, which not only increases the operating cost of the equipment, but also may affect the continuity of monitoring due to energy exhaustion;

[0004] Secondly, fixed monitoring equipment has obvious limitations when the wind direction changes, especially in windy weather. If the air inlet of the equipment is facing away from the wind direction and the air outlet is facing the wind direction, then the air outlet of the fan and the outside wind will form a relative flow. This relative flow will affect the working efficiency of the fan and interfere with the accuracy of the monitoring results. Therefore, an air quality monitoring device is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide an air quality monitoring device to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an air quality monitoring device, including a vertical pole, a base that can rotate freely around the central axis of the vertical pole is arranged at the upper end of the vertical pole, a monitoring box is installed on the upper surface of the base, the vertical pole is a supporting structure of the base and the monitoring box, ensuring that the base and the monitoring box are stably installed, the lower end of the vertical card is connected with a fixing device, the fixing device can be a disc-shaped base structure or a ground spike structure inserted into the ground, a ventilation duct is horizontally penetrated inside the monitoring box, a plurality of monitoring modules for monitoring various air indicators are installed on the side walls of the ventilation duct, the ventilation duct horizontally penetrates the interior of the monitoring box and is open at both ends, one end of the ventilation duct is an air inlet, and the other end is an air outlet, allowing air to flow through, so that a plurality of monitoring modules of different types can monitor various air indicators;

[0007] Among them, a tail rod is installed on the base and along the ventilation direction of the ventilation duct. The end of the tail rod is connected to a wind direction bag. The main function of the tail rod is to connect and support the wind direction bag. When the wind blows, the wind direction bag floats up with the wind and rotates with the base and the monitoring box until the ventilation duct is in the windward position.

[0008] Preferably, a fan is installed inside the ventilation duct via a bracket, and the blowing direction of the fan faces the air outlet of the ventilation duct.

[0009] Preferably, a battery module and a control module are provided inside the monitoring box. The battery module provides power to the monitoring module, the fan and the control module. The control module is electrically connected to the monitoring module and the fan.

[0010] Preferably, the end of the tail rod is rotatably connected to a rotating shaft, a connecting rope is fixedly connected to the rotating shaft, the end of the connecting rope away from the rotating shaft is fixedly connected to the end of the wind direction bag, a trigger module is fixedly connected to the side wall of the rotating shaft, and the end of the tail rod is fixedly connected to the sensing module. When there is no wind, the connecting rope droops, the trigger module does not contact the sensing module, and the fan runs. When there is wind, the wind direction bag swings with the connecting rope, the angle of the rotating shaft changes, the trigger module contacts the sensing module, and the fan does not run.

[0011] Preferably, a photovoltaic panel is provided on the box cover of the monitoring box, and the photovoltaic panel is electrically connected to the battery module.

[0014] Preferably, two side wings are symmetrically arranged on the base with reference to the center line of the ventilation duct, and the tail ends of the two side wings are inclined outwards to form an outward-facing structure.

[0015] Compared with existing technologies:

[0016] 1. The utility model allows the wind direction bag to float with the wind, and drives the base and the monitoring box to rotate through the tail rod. This process will enable the air inlet of the ventilation duct to face the wind direction, that is, to be in the windward position. In the windward position, the ventilation duct can collect air samples more effectively, and air flows in from the air inlet so that the monitoring module can analyze various indicators, save energy consumption, improve the flexibility of the air quality monitor, and ensure the effectiveness of the monitoring data of the air quality monitor.

[0017] 2. In the case of no wind or light wind, the base and monitoring box of the utility model remain stationary, and the wind direction bag is also stationary. At this time, the fan is used to actively draw external air into the ventilation duct, and the air inlet of the ventilation duct collects air samples from the surrounding environment, thereby ensuring the validity of the monitoring data of the air quality monitor.

DETAILED DESCRIPTION

[0025] The present invention is described below with specific embodiments, but is not intended to be a limitation of the present invention.

[0026] Example 1

[0027] like Figure 1-Figure 6 As shown, in this embodiment, an air quality monitoring device is provided, including a pole 1, a base 2 which can rotate freely around the central axis of the pole 1 is arranged at the upper end of the pole 1, a monitoring box 3 is installed on the upper surface of the base 2, the pole 1 is a supporting structure of the base 2 and the monitoring box 3, ensuring that the base 2 and the monitoring box 3 are stably installed, the lower end of the pole 1 is connected with a fixing device, the fixing device can be a disc-shaped base structure or a ground spike structure inserted into the ground, a ventilation duct 4 is horizontally penetrated inside the monitoring box 3, a plurality of monitoring modules 5 for monitoring various air indicators are installed on the side wall of the ventilation duct 4, the ventilation duct 4 horizontally penetrates the interior of the monitoring box 3 and is open at both ends, one end of the ventilation duct 4 is an air inlet, and the other end is an air outlet, allowing air to flow through, so that a plurality of monitoring modules 5 of different types can monitor various air indicators;

[0028] The base 2 is mounted on the upper end of the pole 1 and can rotate freely around the central axis of the pole 1, allowing the base 2 and the components above it (such as the monitoring box 3) to rotate under the action of wind to adapt to changes in wind direction.

[0029] Among them, a tail rod 6 is installed on the base 2 and along the ventilation direction of the ventilation duct 4, and a wind direction bag 7 is connected to the end of the tail rod 6. The main function of the tail rod 6 is to connect and support the wind direction bag 7. When the wind blows, the wind direction bag 7 floats up with the wind and rotates with the base 2 and the monitoring box 3 until the ventilation duct 4 is in the windward position;

[0030] The wind direction bag 7 is connected to the end of the tail rod 6. When the wind blows, it will float with the wind. Since the base 2 can rotate, the fluttering of the wind direction bag 7 will drive the base 2 and the monitoring box 3 to rotate until the ventilation duct 4 is in a windward position (that is, the air inlet of the ventilation duct 4 is facing the air flow direction). In this way, part of the air will flow from the air inlet into the ventilation duct 4. The air sample entering the ventilation duct 4 will contact the detection head of the monitoring module 5 and then flow out from the air outlet. Then, the air can automatically flow into the ventilation duct 4 continuously, which can more effectively capture and monitor the air sample in the wind direction.

[0031] Dust covers 16 are fixedly installed at the opening positions at both ends of the ventilation duct 4. The provision of the dust cover 16 can prevent impurities from entering the interior of the ventilation duct 4, and effectively keep the ventilation duct 4 clean.

[0032] A bearing 17 is provided at the upper end of the vertical pole 1, wherein the upper end of the vertical pole 1 is fixedly connected to the inner ring of the bearing 17, and the base 2 is fixedly connected to the outer ring of the bearing 17. The provision of the bearing 17 can increase the flexibility of the base 2 in rotating on the vertical pole 1.

[0033] Two side wings 18 are symmetrically arranged on the base 2 and based on the central line of the ventilation duct 4. The tail ends of the two side wings 18 are inclined outwards to form an outward-facing structure.

[0034] Example 2

[0035] like Figure 1-Figure 4 As shown, based on Example 1, in order to allow air to flow into the interior of the ventilation duct 4 even in a windless environment, a fan 10 is installed inside the ventilation duct 4 through a bracket, and the blowing direction of the fan 10 is directly facing the air outlet of the ventilation duct 4;

[0036] When air quality monitoring is performed in a windless environment, the fan 10 is turned on. After the fan 10 starts working, the surrounding air will be sucked into the air inlet of the ventilation duct 4, so that air circulation and monitoring can be achieved under windless or light wind conditions, thereby improving the environmental adaptability of the device.

[0037] like Figure 1-Figure 4 As shown, a battery module 11 and a control module 12 are arranged inside the monitoring box 3. The battery module 11 provides power to the monitoring module 5, the fan 10 and the control module 12. The control module 12 is electrically connected to the monitoring module 5 and the fan 10.

[0038] The control module 12 is the central controller of the entire device, and realizes precise control of the monitoring module 5 and the fan 10 through electrical connection with them. The control module 12 has a built-in microprocessor or similar control unit, which can send control signals according to a preset program or external instructions;

[0039] For the monitoring module 5, the control module 12 can set its sampling frequency, data processing method and other parameters to ensure the accuracy and real-time nature of the monitoring data. When the monitoring module 5 captures and analyzes the air sample, it will transmit the data to the control module for processing and storage. In addition, a remote transmission module can be provided on the control module 12 to transmit the collected data outward;

[0040] For the fan 10, the control module 12 can adjust its working state according to environmental conditions and monitoring requirements. For example, in a windless or light breeze environment, the control module 12 can start the fan 10 to enhance the air circulation in the ventilation duct 4; when the wind speed is high, the speed of the fan 10 can be reduced or the fan 10 can be turned off to save electricity.

[0041] like Figure 1-Figure 3 As shown, in order to increase the battery life of the battery module 11 , a photovoltaic panel 15 is provided on the cover of the monitoring box 3 , and the photovoltaic panel 15 is electrically connected to the battery module 11 .

[0042] Example 3

[0043] like Figure 1 , Figure 2 as well as Figure 6 As shown, on the basis of Example 2, in order to connect the wind direction bag 7 to the tail rod 6, and also to adjust the position of the wind direction bag 7 with the wind direction, and to transmit the wind speed signal to the control module 12, the end of the tail rod 6 is rotatably connected to the rotating shaft 8, and the rotating shaft 8 is fixedly connected to the connecting rope 9, and the end of the connecting rope 9 away from the rotating shaft 8 is fixedly connected to the end of the wind direction bag 7, and the side wall of the rotating shaft 8 is fixedly connected to the trigger module 13, and the end of the tail rod 6 is fixedly connected to the sensing module 14. When there is no wind, the connecting rope 9 droops, the trigger module 13 does not contact the sensing module 14, and the fan 10 runs. When there is wind, the wind direction bag 7 swings with the connecting rope 9, the angle of the rotating shaft 8 changes, the trigger module 13 contacts the sensing module 14, and the fan 10 does not run.

[0044] The wind direction bag 7 can not only effectively capture the change of wind direction, but also drive the base 2 and the monitoring box 3 to rotate through the transmission effect of the connecting rope 9 and the rotating shaft 8, so as to ensure that the ventilation duct 4 is always in the best position to collect air samples. This mechanism of automatically adapting to the change of wind direction makes the device more intelligent and efficient, and improves the accuracy and reliability of air quality monitoring.

[0045] Working mechanism in windless state:

[0046] In a windless or light wind environment, the wind direction bag 7 remains in a drooping state due to the lack of wind power. At this time, the connecting rope 9 will also droop naturally, driving the rotating shaft 8 to maintain a relatively fixed position. In this state, the trigger module 13 and the sensing module 14 are staggered and do not contact the sensing module 14. At this time, since the sensing module 14 does not receive a trigger signal, it will send a command to the control module 12, and the control module 12 will then start the fan 10. The operation of the fan 10 enhances the air circulation in the ventilation duct 4, ensuring that the monitoring module 5 can continuously obtain air samples for analysis;

[0047] Working mechanism in windy conditions:

[0048] When there is wind, the wind direction bag 7 will swing due to the wind force, and this swing is transmitted to the rotating shaft 8 through the connecting rope 9, so that the angle of the rotating shaft 8 changes. As the rotating shaft 8 rotates, the trigger module 13, which was originally drooping, will rise until it contacts the sensing module 14. When the sensing module 14 contacts the trigger module 13, it will send a signal to the control module 12 to inform the current wind state. After receiving this signal, the control module 12 will immediately turn off the fan 10 to save energy.
