Description

Technical Field

[0001] The present application relates to the field of environmental monitoring equipment, and in particular to an environmental protection monitoring equipment. Background Art

[0002] A water quality monitoring station is a facility dedicated to monitoring water quality. It collects water samples and analyzes them to assess the chemical composition, physical properties, and biological characteristics of the water to determine whether the water quality meets relevant standards and requirements.

[0003] Online water quality monitoring stations are widely used in the current market. They consist of two parts: a floating sensor in the water and a monitoring station on the water. The floating water quality sensor is always in the water, and the environment in the water is relatively complex. Garbage, branches, suspended matter, sediment, etc. in the water are easily attached to the sensor, thus affecting the monitoring quality. Most of the existing water quality sensors are not equipped with self-cleaning functions, and they have to be fished out and cleaned manually every time.

[0004] Therefore, we use this technical solution to solve the problem that the existing water quality sensor is inconvenient to clean. Summary of the invention

[0005] The purpose of the present application is to improve the environmental monitoring equipment in the prior art, and to provide an environmental protection monitoring equipment compared to the prior art, by adding an outer protective tube on the basis of the existing online water quality sensor to protect the detection end of the monitoring rod, by adding an obstacle sensing rod to construct a protection line on the periphery of the monitoring rod, so as to effectively prevent garbage bags, branches and other debris floating in the water from covering the monitoring rod and hindering normal detection, and by using a vibration motor to transmit vibration to the obstacle sensing rod, when there are debris attached to the obstacle sensing rod, it will affect its vibration frequency, and by using a vibration frequency detector to detect the vibration frequency of the obstacle sensing rod and thereby start the electromagnet to repel the obstacle removal ring downward, thereby realizing automatic cleaning of the outer surface of the monitoring rod, and effectively preventing aquatic organisms and foreign matter from adhering to the monitoring rod.

[0006] Realize self-cleaning of water quality sensors, effectively prevent aquatic organisms and debris from affecting monitoring, and effectively improve the real-time and accuracy of water quality monitoring.

[0007] Furthermore, a polyurethane scraping ring is fixedly connected to the inner side wall of the obstacle removal ring, and the polyurethane scraping ring is in contact with the monitoring rod. The polyurethane scraping ring is in contact with the outer surface of the lower end of the monitoring rod. When the obstacle removal ring moves downward, the polyurethane scraping ring can scrape off the organisms and debris attached to the outer surface of the monitoring rod, thereby realizing automatic cleaning of the monitoring rod, thereby effectively improving the accuracy of water quality monitoring.

[0008] Optionally, the upper side wall of the obstacle clearing ring is also fixedly connected to a plurality of connecting rods that are equally spaced and distributed around, and the upper ends of the plurality of connecting rods are also fixedly connected to an attachment scraping ring that contacts the monitoring rod. The attachment scraping ring contacts the upper outer surface of the monitoring rod and is responsible for cleaning the upper half of the monitoring rod, and cooperates with the polyurethane scraping ring to clean the lower half, thereby achieving cleaning of attachments on the entire monitoring rod.

[0009] Furthermore, a cleaning pad is fixedly connected to the attachment scraping ring and the clearance hole, and the cleaning pad is made of waterproof material. The cleaning pad can scrape and clean the attachments on the monitoring rod, effectively avoiding wear of the attachment scraping ring and the clearance hole, thereby effectively extending the service life.

[0010] Furthermore, the vibration transmission component includes a rubber membrane, and a polyurethane elastic sheet is placed in the middle of the rubber membrane, and the interior of the polyurethane elastic sheet is filled with rubber filler. The vibration transmission component connects the obstacle sensing rod and the connecting shell together. The two ends of the rubber membrane and the polyurethane elastic sheet are respectively connected to the obstacle sensing rod and the inner wall of the connecting shell. The rubber filler relies on its own elastic force to achieve a soft connection between the obstacle sensing rod and the vibration motor. In this way, when the vibration motor drives the obstacle sensing rod to vibrate, it can effectively avoid resonance and cause damage to the obstacle sensing rod. Moreover, when the debris in the water covers the obstacle sensing rod, the elastic force can change the vibration frequency of the obstacle sensing rod, thereby being detected by the vibration frequency detector.

[0011] Furthermore, the elastic sealing ring is annular in structure and is made of elastic waterproof material. The elastic sealing ring relies on its own elastic force to adhere tightly to the obstacle sensing rod, thereby playing an effective sealing role and effectively preventing water from penetrating into the interior and damaging the vibration frequency detector and the vibration motor.

[0012] Compared with the prior art, the advantages of this application are:

[0013] (1) This scheme protects the detection end of the monitoring rod by adding an outer protective tube to the existing online water quality sensor, and constructs a protective line on the periphery of the monitoring rod by adding an obstacle sensing rod, which effectively prevents garbage bags, branches and other debris floating in the water from covering the monitoring rod and hindering normal detection. The vibration motor is used to transmit vibration to the obstacle sensing rod. When debris sticks to the obstacle sensing rod, it will affect its vibration frequency. The vibration frequency detector is used to detect the vibration frequency of the obstacle sensing rod and use it to start the electromagnet to repel the obstacle removal ring downward, thereby realizing automatic cleaning of the outer surface of the monitoring rod, effectively preventing aquatic organisms and foreign matter from attaching to the monitoring rod, realizing self-cleaning of the water quality sensor, effectively preventing aquatic organisms and debris from affecting monitoring, and effectively improving the real-time and accuracy of water quality monitoring.

[0014] (2) A polyurethane scraping ring is fixedly connected to the inner side wall of the obstacle removal ring, and the polyurethane scraping ring is in contact with the monitoring rod. The polyurethane scraping ring is in contact with the outer surface of the lower end of the monitoring rod. When the obstacle removal ring moves downward, the polyurethane scraping ring can scrape off the organisms and debris attached to the outer surface of the monitoring rod, thereby realizing automatic cleaning of the monitoring rod, thereby effectively improving the accuracy of water quality monitoring.

[0015] (3) The upper side wall of the obstacle removal ring is also fixedly connected to a plurality of connecting rods that are equally spaced and distributed around it, and the upper ends of the plurality of connecting rods are also fixedly connected to a scraper ring that contacts the monitoring rod. The scraper ring contacts the upper outer surface of the monitoring rod and is responsible for cleaning the upper half of the monitoring rod, and cooperates with the polyurethane scraper ring to clean the lower half, thereby achieving the cleaning of the entire monitoring rod.

[0016] (4) A cleaning pad is fixedly connected to the scraper ring and the clearance hole, and the cleaning pad is made of waterproof material. The cleaning pad can scrape and clean the attachments on the monitoring rod and the obstacle sensing rod, effectively avoiding the wear of the scraper ring and the clearance hole, thereby effectively extending the service life.

[0017] (5) The vibration transmission component includes a rubber membrane, and a polyurethane elastic sheet is placed in the middle of the rubber membrane. The interior of the polyurethane elastic sheet is filled with rubber filler. The vibration transmission component serves to connect the obstacle sensing rod and the connecting shell together. The two ends of the rubber membrane and the polyurethane elastic sheet are respectively connected to the obstacle sensing rod and the inner wall of the connecting shell. The rubber filler relies on its own elastic force to achieve a soft connection between the obstacle sensing rod and the vibration motor. In this way, when the vibration motor drives the obstacle sensing rod to vibrate, it can effectively avoid resonance and cause damage to the obstacle sensing rod. In addition, when the debris in the water covers the obstacle sensing rod, the elastic force can change the vibration frequency of the obstacle sensing rod, thereby being detected by the vibration frequency detector.

[0018] (6) The elastic sealing ring is annular in structure and is made of elastic waterproof material. The elastic sealing ring relies on its own elastic force to adhere tightly to the obstacle sensing rod, thereby playing an effective sealing role and effectively preventing water from penetrating into the interior and damaging the vibration frequency detector and the vibration motor.

[0034] See also Figure 6 , 7 and Figure 8The lower end of the obstacle sensing rod 12 is flush with the bottom of the monitoring rod 2.

Example

[0036] Based on Example 1, please refer to Figure 5The upper side wall of the obstacle removal ring 5 is also fixedly connected to a plurality of connecting rods 17 that are equidistantly distributed around, and the upper ends of the plurality of connecting rods 17 are simultaneously fixedly connected to an attachment scraper ring 18 that contacts the monitoring rod 2.

[0037] The working principle of this scheme is as follows: when the monitoring rod 2 is in a normal monitoring state in the water, the vibration generated by the vibration motor 10 is transmitted to the obstacle sensing rod 12 through the connecting shell 11 and the vibration transmission member 13. At this time, the vibration frequency of the obstacle sensing rod 12 is in a stable state. When plastic bags, branches and other debris floating in the water are close to the lower end of the monitoring rod 2, they will first contact the obstacle sensing rod 12. The obstacle sensing rod 12 can prevent the debris from covering the monitoring rod 2, thereby ensuring the normal monitoring work of the monitoring rod 2. When the debris covers the obstacle sensing rod 12, the vibration frequency of the obstacle sensing rod 12 will be affected by the adhesion of the debris. At this time, the vibration frequency detector 14 detects that the vibration frequency of the obstacle sensing rod 12 is abnormal, and then starts the electromagnet 7 to generate magnetic force to repel the magnetic ring 8 downward. The downward movement of the magnetic ring 8 causes the obstacle removal ring 5 to move downward, thereby realizing the cleaning of the lower half of the monitoring rod 2 and the obstacle sensing rod 12, and scraping off the attachments on the monitoring rod 2 and the obstacle sensing rod 12.
