Abstract
Description
Technical Field
[0001] This utility model relates to the field of watershed pollution monitoring technology, and in particular to a monitoring device for non-point source pollution in small watersheds. Background Technology
[0002] A watershed is the catchment area of a river or river system, that is, the entire region through which the main stream and tributaries of a river flow. It is surrounded by a watershed line, which is the boundary between adjacent watersheds. It is usually the track line formed by the topographic watershed around the watershed. A watershed is a relatively independent natural geographical unit with unique hydrological cycles and ecological processes. It includes not only the river itself, but also the alluvial plains on both sides of the river and the area surrounded by the watershed formed by the mountains or highlands on both sides of the river channel. Watersheds can be divided according to different principles: according to topography, watersheds can be divided into mountain watersheds and plain watersheds; according to climate and the surface material conditions in the watershed, watersheds can be divided into forest watersheds, grassland watersheds, and desert watersheds; according to the size of the watershed, watersheds can be divided into large watersheds, medium watersheds, and small watersheds.
[0003] Watershed monitoring requires the use of detection probes to detect the water quality of the watershed. However, detection probes are often unable to be flexibly adjusted according to the detection depth, and therefore cannot be adapted to the detection of water quality in different watersheds. Utility Model Content
[0004] Given that watershed monitoring requires the use of detection probes to detect water quality, but these probes often cannot be flexibly adjusted according to the detection depth, thus failing to adapt to the detection of water quality in different watersheds, this utility model was proposed.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a monitoring device for non-point source pollution in small watersheds, comprising a base, an adjustment component at the middle of the base, a motor at the upper end of the base, a ball screw at the output end of the motor, a ball sleeve on the upper end of the outer wall of the ball screw, a first sliding rod inserted at one symmetrical end of the ball sleeve and the ball screw, a connecting frame on the outer wall of the ball sleeve, a detection probe at the lower end of the connecting frame, a protective net at the lower end of the connecting frame, and a water level monitoring component on one side of the outer wall of the base. The water level monitoring component includes a fixing block at the upper end of the outer wall of the base, two sets of second sliding rods symmetrically arranged at both ends of the fixing block, a sliding sleeve on the outer wall of the second sliding rod, a float at the lower end of the sliding sleeve, and a striking rod at the upper end of the sliding sleeve.
[0006] As a preferred embodiment of the monitoring device for non-point source pollution in small watersheds described in this utility model, wherein: the end of the ball screw away from the motor is rotatably connected to the bottom end of the base, the ball screw sleeve is movably inserted into the inner wall of the base, the upper and lower ends of the first slide rod are fixedly connected to the base, and the ball screw sleeve is movably sleeved on the outer wall of the first slide rod.
[0007] As a preferred embodiment of the monitoring device for non-point source pollution in small watersheds described in this utility model, the protective net is threaded onto the outer wall of the lower end of the connecting frame.
[0008] As a preferred embodiment of the monitoring device for non-point source pollution in small watersheds described in this utility model, the lower end of the base is fixedly provided with a pointed cone, the lower ends of the base are provided with support plates, and the lower ends of the support plates are provided with threaded holes.
[0009] As a preferred embodiment of the monitoring device for non-point source pollution in small watersheds described in this utility model, the sliding sleeve is movably fitted onto the outer wall of the second sliding rod.
[0010] As a preferred embodiment of the monitoring device for non-point source pollution in small watersheds described in this utility model, the water level monitoring component further includes an alarm button located at the lower end of the fixed block, a controller and an alarm are respectively provided at the upper end of the base, and a photovoltaic panel and a storage battery are respectively provided at the upper and lower ends of one side of the outer wall of the base, and the photovoltaic panel, storage battery, controller, alarm and alarm button are electrically connected to each other.
[0011] As a preferred embodiment of the monitoring device for non-point source pollution in small watersheds described in this utility model, the base has a scale on its back.
[0012] Compared with the prior art, the present invention has at least the following beneficial effects:
[0013] 1. In this utility model, when it is necessary to test the water quality of a water area, the motor can be started to drive the ball screw to rotate. The ball screw drives the ball sleeve to move downward along the first slide bar. The depth of the detection probe is calculated by the scale. The detection probe can move up and down in the vertical direction to test the water quality at different depths in the water area. The protective net is set to prevent hard impurities such as mud and sand in the water from impacting the detection probe and causing damage to it under the action of water flow.
[0014] 2. In this utility model, when the water level rises during summer rainstorms, the float moves upward under the buoyancy of the water, and the sliding sleeve slides upward along the outer wall of the second sliding rod. When the water level rises significantly, the sliding sleeve drives the striking rod upward to trigger the alarm button. The alarm button transmits a signal to the controller, which controls the alarm to produce a piercing siren sound to remind monitoring personnel to take flood prevention measures and facilitate staff to understand the situation and carry out subsequent drainage treatment.

[0024] The end of the ball screw 22 away from the motor 21 is rotatably connected to the bottom end of the base 1. The ball sleeve 23 is movably inserted into the inner wall of the base 1. The upper and lower ends of the first slide rod 24 are fixedly connected to the base 1. The ball sleeve 23 is movably sleeved on the outer wall of the first slide rod 24.
[0025] The protective net 27 is threaded onto the lower outer wall of the connecting frame 25.
[0026] A pointed cone 9 is fixedly provided at the lower end of the base 1, and support plates 3 are provided on both sides of the lower end of the base 1. Threaded holes are opened at the lower end of the support plates 3.
[0027] The cone 9 at the lower end of the base 1 is inserted into the soil.
