Description

A portable hydrological and water resources surveying device

Technical Field

The utility model relates to the technical field of water resource survey, in particular to a convenient hydrological and water resource survey device.

Background technique

Hydrology is an important basic work for national economic construction and social development. Through long-term and continuous observation of flow, water level, precipitation, evaporation, sediment, water quality, groundwater, water temperature, ice and other items, we collect systematic and comprehensive hydrological data. Through hydrological intelligence forecasting, water resources analysis and calculation, water resources evaluation, water quality evaluation and other work, we provide services for comprehensive basin management and development, flood control and drought relief, engineering construction, water resources development and sustainable utilization.

After searching, the Chinese patent publication number CN216285242U discloses a convenient hydrological and water resources surveying device, in which the adjustment hand wheel on the main control box conveniently drives the moving push plate to move and adjust, thereby regulating the buoyancy of the floating box in the water and surveying the water resources in the water at depth.

By comparing with the existing technologies in related fields, it can be seen that when the existing hydrological and water resources surveying devices are used, most of them install weights on the detection probes so that the detection probes are placed directly in the river water for detection. When conducting surveys, the stability of the probes in the river water is poor when the existing devices are used, and it is not convenient to control the detection depth. Different samples are required for sampling and testing during the survey. When the existing devices are used, it is not convenient to sample river water, aquatic plants and riverbed soil at different depths, which greatly slows down the efficiency of the survey.

Utility Model Content

The purpose of the utility model is to provide a convenient hydrological and water resources surveying device in order to solve the above problems.

The utility model achieves the above-mentioned purpose through the following technical solutions:

A portable hydrological and water resources surveying device comprises an installation box, a displacement unit with a displacement function is installed on the lower surface of the installation box, an adjustment unit with a position adjustment function is installed on the installation box, and a detection sampling unit with a detection sampling function is installed on the adjustment unit. The installation box is driven to move by the displacement unit, thereby increasing the convenience of movement of the entire device. The depth and position of the detection sampling unit in river water are adjusted by the adjustment unit, and the river water is sampled and detected by the detection sampling unit.

The adjustment unit includes a driving component, a placement slot, and an extension rod. The driving component and the placement slot are both installed on the installation box. The extension rod is slidably installed on the driving component and the placement slot. Threaded columns and threaded holes are respectively provided at the upper and lower ends of the extension rod. A rack is provided on the side of the extension rod. The rack is connected to the driving component, and the threaded column is connected to the detection sampling unit. When the extension rod is not in use, it is placed in the placement slot, which increases the stability and firmness during movement and the convenience during storage. The extension rod is installed on the driving component, and the detection sampling unit is installed on the extension rod. The threaded column and the threaded hole facilitate the connection of the two extension rods, which are convenient for storage when not in use. According to the required depth of the river water, a suitable number of extension rods are selected for connection. The driving component drives the detection sampling unit into the river water through the extension rod, so that the river water of different depths can be sampled and tested as needed. The detection sampling unit is driven into the river water by the extension rod, which effectively improves the stability of the detection sampling unit in the river water;

The detection sampling unit includes a connecting seat, which is threadedly installed on a threaded column. A second motor and a detection probe are arranged on the connecting seat. The output shaft of the second motor is connected to a sampling box. A water sampling component, a water plant sampling component and a silt sampling component are arranged in the sampling box. The input end of the second motor is electrically connected to the output end of the external controller. The second motor and the detection probe work using existing technology. The flow rate, water temperature, water quality and other conditions of the river water are detected by the detection probe. The sampling box is driven to rotate by the second motor, and the river water is sampled by the water sampling component in the sampling box, the water plants in the river water are sampled by the water plant sampling component in the sampling box, and the soil in the river channel is sampled by the silt sampling component in the sampling box, thereby completing the survey of the river channel hydrology and water resources.

The driving assembly includes a first hydraulic cylinder and a first motor. The first hydraulic cylinder is installed on the installation box. The first hydraulic cylinder is connected to a mounting seat. The mounting seat is slidably connected to an extension rod. The first motor is installed on the mounting seat.

The input ends of the first hydraulic cylinder and the first motor are electrically connected to the output end of an external controller. The external controller controls the operation of the first hydraulic cylinder and the first motor using existing technology. In order to sample river water in the center of a river channel, the device needs to be installed on a ship for use. When the installation box is installed on the ship for use, the mounting seat is extended by the first hydraulic cylinder, and the mounting seat drives the detection sampling unit to move through the extension rod, so that the detection sampling unit is moved out of the cabin.

When the sampling box enters the river water, the liquid inlet hole is blocked by the inverted U-shaped clamp ring to prevent the river water from entering the liquid inlet hole. When the sampling box reaches the sampling depth, the river water enters the liquid storage chamber through the liquid inlet hole to complete the sampling of the river water at a fixed depth. After the sampling is completed, the liquid inlet hole is closed by the inverted U-shaped clamp ring, thereby effectively avoiding mixed contamination of the sample and ensuring the accuracy of the sample detection.
