Description

Technical Field

[0001] The invention relates to the technical field of runoff sediment monitoring, in particular to a runoff sediment monitoring device. Background Art

[0002] Monitoring of runoff sediment content is an important part of hydrological monitoring. Monitoring of sediment content can help relevant departments understand the situation of soil erosion in the monitoring area. Rapid, accurate and continuous monitoring of sediment content is of great significance to river ecological protection and the safe operation of water conservancy projects.

[0003] In the prior art, when monitoring runoff sediment, the device is placed in a river with its underwater part arranged along the direction of the water flow, the water flows into the device from the water inlet, and larger impurities such as algae in the water flow are filtered out through a filter screen, the filtered water flows into a monitoring room, and data is collected through a flow meter and an infrared sediment sensor, and the sediment content is calculated based on the collected data; however, the prior art cannot self-clean the sediment inside the monitoring room. As the monitoring room is used, some sediment will remain inside the monitoring room, and the surfaces of the flow meter and the infrared sediment sensor will be covered with sediment, which can easily affect the accuracy of the monitoring data. In addition, when the monitoring room needs to be cleaned, the entire device needs to be taken out. However, since the runoff needs to be continuously detected, the monitoring will be interrupted for a long time when the device is taken out for cleaning, which will affect the continuous collection of data.

[0039] The inner wall of the monitoring tube 9 is provided with a first vertical rod 22 and a second vertical rod 25, on which a first movable shaft 23 and a second movable shaft 26 are rotatably provided respectively, the first movable shaft 23 is connected to an infrared sediment sensor 24, and the second movable shaft 26 is connected to a flow meter 27, the infrared sediment sensor 24 is used to monitor sediment in the water, and the flow meter 27 is used to monitor the speed of the water flow;

[0040] It also includes: a lifting component 2, the two ends of which are respectively connected to the mounting frame 3 and the supporting frame 1, and are used to adjust the monitoring depth of the monitoring tube 9;

[0041] It also includes: a rotating component 6, which is arranged on both sides of the mounting frame 3 and is used to drive the rotating shaft 4 to drive the rotating frame 5 to rotate so that the monitoring tube 9 is displaced;

The closing component 16 includes extension rods 1601 installed on both sides of the mounting frame 3, and the extension rods 1601 are located above the rotating shaft 4. The first magnet 1602 is installed at one end of the extension rod 1601 away from the mounting frame 3, and the second magnet 1603 is arranged on both sides of the rear tail plate 14. The monitoring tube 9 located above will be pressed against the end of the monitoring tube 9 under the action of the repulsive force because the second magnet 1603 in the rear tail plate 14 is close to the first magnet 1602 on the extension rod 1601;

[0043] The monitoring tube 9 also includes a sealing tube 18, the outer wall of which is provided with support rods 17 distributed in an annular manner, and the support rods 17 are connected to the inner wall of the monitoring tube 9.

[0044] The first cleaning component 19 is disposed on the sealing cylinder 18 and passes through the monitoring cylinder 9 to contact the first filter screen 12, and is used to clean impurities on the first filter screen 12;

[0045] The second cleaning component 20 is provided on the sealing cylinder 18 and passes through the rear tail plate 14 to contact the second filter screen 15, and is used to clean impurities on the second filter screen 15;

[0046] It also includes a rotating head component 28 , which is connected to the first vertical rod 22 and the second vertical rod 25 , and is also connected to the rear tail plate 14 , and is used to adjust the directions of the infrared sediment sensor 24 and the flow meter 27 .

[0047] The support frame 1 is set up beside the river where sediment monitoring is required, and then the monitoring depth of the monitoring tube 9 in the river water is adjusted by the lifting component 2. The monitoring tube 9 located at the bottom and with the water inlet 8 opposite to the flow direction of the water flow will monitor the sediment.

The sediment situation in the water flow is monitored by the infrared sediment sensor 24, and the flow rate is measured by the flow rate sensor 24. The instrument 27 monitors the flow rate of the water flow, and calculates the amount of sediment in the water flow through the collected data. Under the action of the elastic component 13, there is a large gap between the rear tail plate 14 and the monitoring tube 9, so that the water in the monitoring tube 9 can flow out of the gap; and when it is necessary to clean the sediment in the monitoring tube 9, the rotating shaft 4 can be rotated by the rotating component 6, and then the rotating frame 5 can be driven to rotate 180 degrees, so that the monitoring tube 9 that needs to be cleaned is rotated to the top. At this time, the rear tail plate 14 of the monitoring tube 9 is opposite to the flow direction of the water flow, and the monitoring tube 9 originally located at the top will rotate to the bottom, and at the same time, the monitoring tube 9 The water inlet 8 of the monitoring tube 9 will be opposite to the flow direction of the water flow, and the monitoring tube 9 will continue to monitor the sediment at this time; after the monitoring tube 9 to be cleaned rotates 180 degrees, the first magnet 1602 and the second magnet 1603 on the closing component 16 will be close to each other, and the rear tail plate 14 will be pressed against the end of the monitoring tube 9 through the repulsive force of the first magnet 1602 and the second magnet 1603 and the water flow, thereby blocking the open end of the monitoring tube 9.
