Description

Technical Field

[0001] The utility model relates to the technical field of environmental pollution monitoring instruments, in particular to an environmental pollution monitoring instrument. Background Art

[0002] Environmental monitoring instruments are a general term for instruments used to monitor various parameters of indoor and outdoor environments. By measuring the representative values of factors affecting environmental quality, the environmental monitoring process generally includes accepting tasks, on-site investigation and data collection, monitoring plan design, optimization of distribution points, sample collection, sample transportation and storage, sample pretreatment, analysis and testing, data processing, comprehensive evaluation, etc., including air, exhaust gas monitoring instruments, flue gas SO2, fixed, portable motor vehicle exhaust monitors and rainfall and other monitoring instruments.

[0003] However, existing environmental pollution monitoring instruments can monitor outdoor air, rainfall and motor vehicle exhaust. For example, an environmental pollution monitoring instrument with application number: "202322438522.7" includes a display, the top of the display is rotatably connected to a support rod, the top of the support rod is fixedly connected to a main rod, one end of the main rod is rotatably connected to a fan blade, the other end of the main rod is fixedly connected to a tail wing, and one side of the main rod is fixedly connected to a connecting rod. The utility model can achieve that after the instrument is fixed in the corresponding position, when the wind direction changes, since the tail wing has a relatively large wind-receiving area, it will follow the wind direction to drive the support rod to rotate, and drive the upper monitoring mechanism to rotate. Since the ventilation frame in the monitoring mechanism is parallel to the main rod, it will directly monitor in parallel with the air and transmit it to the display via Bluetooth, thereby achieving the goal of not having to manually adjust the direction during the monitoring process, and the instrument will rotate according to the wind direction, thereby saving the labor and energy of adjusting the direction during the monitoring process.

[0004] However, when existing environmental pollution monitoring instruments monitor the pH value of rainfall, when there is strong wind, the strong wind will blow the fallen leaves into the inside of the funnel, and then enter the inside of the sump along with the rainwater. In this case, the monitoring data is inaccurate. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides an environmental pollution monitoring instrument, which solves the problem that when monitoring the pH value of rainfall, when strong winds occur, the strong wind will blow fallen leaves into the inside of the funnel, and then enter the inside of the sump along with the rainwater, and the monitoring data in this case is inaccurate.

[0006] To achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: an environmental pollution monitoring instrument, comprising an instrument body, a filtering device is provided on the top of the instrument body, the filtering device comprises a water inlet pipe, a first electric valve, a funnel, a filter plate, a first drain pipe and a cap body, one end of the water inlet pipe is connected to the top of the instrument body, the other end of the water inlet pipe is installed with a first electric valve, the other end of the first electric valve is connected to the funnel, the inner wall of the funnel is fixedly connected with the filter plate, one side of the funnel is connected with the first drain pipe, and the outer wall of the other end of the first drain pipe is buckled with the cap body.

[0007] Preferably, a straight plate is fixedly connected to the inner wall of the instrument body, a water collecting tank is fixedly connected to the top of the straight plate, an inclined plate is fixedly connected to the inner wall of the water collecting tank, a pH value detection rod is fixedly connected to the top of the inclined plate, a water level sensor fixedly connected to the inner wall of the water collecting tank is provided above the pH value detection rod, a second electric valve is installed on one side of the outer wall of the water collecting tank, the other end of the second electric valve is connected to a second drain pipe, and the water outlet end of the second drain pipe passes through the outer wall of the instrument body and extends out of the instrument body.

[0008] Preferably, a controller is installed on the front of the instrument body.

[0009] Preferably, mounting blocks are fixedly connected to both sides of the outer wall of the instrument body, wind vanes are installed on the tops of the two mounting blocks, and a PM value detector is fixedly connected to the top of the instrument body.

[0010] Preferably, a display screen is electrically connected to the bottom of the instrument body via a wire.

[0011] Beneficial effects

[0012] The utility model provides an environmental pollution monitoring instrument. It has the following beneficial effects: The environmental pollution monitoring instrument cooperates with a first electric valve, a filter plate, and a first drain pipe. When the pH value of rainfall needs to be detected, rainwater enters the instrument body through a funnel and a water inlet pipe. The filter plate on the inner wall of the funnel blocks debris blown in by strong winds, ensuring that only rainwater flows into the instrument body, thereby ensuring the accuracy of the detected value. After the rainwater has been collected, the first electric valve is closed, and the cap can be opened to allow the rainwater in the funnel to flow out through the first drain pipe, thereby preventing the next rainfall from mixing with the previous rainfall.

[0013] Through the cooperation between the inclined plate, the second drain pipe and the pH detection rod, when rainwater is collected into the water collection tank, the water level sensor can sense the depth of the rainwater inside the water collection tank. When the water depth reaches the water level sensor, the first electric valve is controlled by the controller to prevent rainwater from entering the water collection tank, thereby preventing rainwater from flooding the top of the water collection tank. The rainwater is then tested by the pH detection rod. After the test, the second electric valve is opened, and the rainwater inside the water collection tank can be discharged to the outside through the second drain pipe under the action of the inclined plate.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] When existing environmental pollution monitoring instruments monitor the pH value of rainfall, when there is strong wind, the strong wind will blow the fallen leaves into the inside of the funnel, and then enter the inside of the sump along with the rainwater. In this case, the monitoring data is inaccurate.

[0021] In view of this, the utility model provides an environmental pollution monitoring instrument. Through the cooperation between the first electric valve, the filter plate and the first drain pipe, when the pH value of rainfall needs to be detected, the rainwater enters the instrument body through the funnel and the water inlet pipe. The filter plate on the inner wall of the funnel will block the debris blown in by the strong wind, ensuring that only rainwater flows into the interior of the instrument body, thereby ensuring the accuracy of the detection value. After the rainwater has been collected, the first electric valve is closed, and the cap body can be opened, and the rainwater inside the funnel can flow out through the first drain pipe, thereby avoiding the next rainfall and the previous rainwater from mixing together.

[0022] Through the use of wires by those skilled in the art, all electrical components in this case are connected to their corresponding power supplies, and appropriate controllers and encoders should be selected according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the following working principle, in which the electrical components are electrically connected in sequence. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and no longer explains the electrical control.

[0023] Example 1: By Figure 1-4 It can be seen that an environmental pollution monitoring instrument includes an instrument body 1, and a filtering device is provided on the top of the instrument body 1. The filtering device includes a water inlet pipe 4, a first electric valve 5, a funnel 6, a filter plate 7, a first drain pipe 8 and a cap body 9. One end of the water inlet pipe 4 is connected to the top of the instrument body 1, and the other end of the water inlet pipe 4 is installed with the first electric valve 5. The specific model of the first electric valve 5 is not specifically limited here. The other end of the first electric valve 5 is connected to the funnel 6, and the inner wall of the funnel 6 is fixedly connected to the filter plate 7. The filter plate 7 isolates debris mixed in rainwater. One side of the funnel 6 is connected to the first drain pipe 8, and the outer wall of the other end of the first drain pipe 8 is buckled with a cap body 9.

[0024] In the specific implementation process, it is worth noting that when the pH value of rainfall needs to be tested, rainwater enters the instrument body 1 through the funnel 6 and the water inlet pipe 4. The filter plate 7 on the inner wall of the funnel 6 will block the debris blown in by the strong wind, ensuring that only rainwater flows into the interior of the instrument body 1, which can ensure the accuracy of the test value. After the rainwater has been collected, the first electric valve 5 is closed, and the cap body 9 can be opened to allow the rainwater inside the funnel 6 to flow out through the first drain pipe 8, thereby preventing the next rainfall from mixing with the previous rainfall.

[0025] Furthermore, the inner wall of the instrument body 1 is fixedly connected with a straight plate 2, the top of the straight plate 2 is fixedly connected with a water collecting tank 19, the inner wall of the water collecting tank 19 is fixedly connected with an inclined plate 18, the top of the inclined plate 18 is fixedly connected with a pH value detection rod 17, the model of the pH value detection rod 17 is not specifically limited here, and a water level sensor 16 fixedly connected to the inner wall of the water collecting tank 19 is provided above the pH value detection rod 17. A second electric valve 13 is installed on one side of the outer wall of the water collecting tank 19, and the other end of the second electric valve 13 is connected to the second drain pipe 12. The water outlet end of the second drain pipe 12 passes through the outer wall of the instrument body 1 and extends out of the instrument body 1. The model of the second electric valve 13 is not specifically limited here;

[0026] During the specific implementation process, it is worth noting that when rainwater is collected in the water collection tank 19, the water level sensor 16 can sense the depth of the rainwater in the water collection tank 19. When the water depth reaches the water level sensor 16, the controller 20 controls the first electric valve 5 to prevent the rainwater from entering the water collection tank 19, thereby preventing the rainwater from flooding the top of the water collection tank 19. The rainwater is then tested by the pH value detection rod 17. After the test is completed, the second electric valve 13 is opened, and the rainwater in the water collection tank 19 can be discharged to the outside through the second drain pipe 12 under the action of the inclined plate 18.

[0027] Furthermore, a controller 20 is installed on the front of the instrument body 1, and the model of the controller 20 is not specifically limited here;

[0028] In the specific implementation process, it is worth noting that when the depth of rainwater inside the sump 19 reaches the water level sensor 16, the signal sent by the water level sensor 16 is transmitted to the controller 20, and the controller 20 controls the first electric valve 5 to close, thereby preventing excessive rainwater inside the sump 19;

[0029] Specifically, when using the environmental pollution monitoring instrument, when it is necessary to detect the pH value of rainfall, rainwater enters the instrument body 1 through the funnel 6 and the water inlet pipe 4. The filter plate 7 on the inner wall of the funnel 6 will block the debris blown by the strong wind, ensuring that only rainwater flows into the interior of the instrument body 1, which can ensure the accuracy of the detection value. After the rainwater has been collected, the first electric valve 5 is closed. The cap body 9 can be opened, and the rainwater inside the funnel 6 can flow out through the first drain pipe 8 to avoid the next rainfall and the previous rainwater from mixing together. When the rainwater is collected in the water collection tank 19, the water level sensor 16 can sense the rainwater in the water collection tank 19. When the water depth reaches the water level sensor 16, the first electric valve 5 is controlled by the controller 20 to prevent rainwater from entering the water collection tank 19, thereby preventing rainwater from flooding the top of the water collection tank 19. The rainwater is then detected by the pH value detection rod 17. After the detection, the second electric valve 13 is opened, and the rainwater inside the water collection tank 19 can be discharged to the outside through the second drain pipe 12 under the action of the inclined plate 18. When the rainwater depth inside the water collection tank 19 reaches the water level sensor 16, the signal sent by the water level sensor 16 is transmitted to the controller 20, and the controller 20 can control the first electric valve 5 to close, thereby preventing excessive rainwater inside the water collection tank 19.

[0030] Example 2: By Figure 1-4 As can be seen, mounting blocks 11 are fixedly connected to both sides of the outer wall of the instrument body 1, and wind vanes 3 are installed on the tops of the two mounting blocks 11. A PM value detector 10 is fixedly connected to the top of the instrument body 1. The model of the PM value detector 10 is not specifically limited here.

[0031] In the specific implementation process, it is worth noting that the wind direction and wind speed can be observed through the two wind vanes 3, and the PM value detector 10 can detect the PM value of the external air;

[0032] Furthermore, the lower portion of the instrument body 1 is electrically connected to a display screen 14 via a wire 15;

[0033] In the specific implementation process, it is worth noting that the values detected by the pH value detection stick 17 and the PM value detector 10 can be displayed through the display screen 14, which is convenient for observation and recording;

[0034] Specifically, based on the above-mentioned embodiment 1, the wind direction and wind speed can be observed through the two wind vanes 3, the PM value detector 10 can detect the PM value of the external air, and the values detected by the pH value detection stick 17 and the PM value detector 10 can be displayed through the display screen 14, which is convenient for observation and recording.
