Pedal type automatic closing type submerged plant quantitative collection device

Abstract

The invention provides a pedal type automatic closing type submerged plant quantitative collection device. The device comprises a main frame, a clamping assembly, a force application assembly, a locking-releasing mechanism and a force storage assembly; wherein the main frame comprises parallel sliding rails, a frame vertical plate and a comb-shaped pressing rake; the clamping assembly comprises a strip-shaped sliding block and a tooth rake fixed to the lower portion of the strip-shaped sliding block. The force application assembly comprises a driving pedal, a driven pedal, a locking pin, a limiting rolling shaft and a pedal support. The locking-releasing mechanism comprises a locking lifting lug and a locking sheath; the force storage assembly comprises a pair of outer spring force accumulators and a pair of inner spring force accumulators. The device has a regular frame structure, and the sampling area is determined; force is applied in a pedal mode, operation is labor-saving, and an operator is not prone to fatigue; the device is released through the rope, is not limited by water depth, and is wide in water body application range; according to the device, submerged plants are collected in a tooth rake clamping mode, and complete plants can be obtained; the device is small in size and convenient to transport and carry.

Description

technical field [0001] The invention belongs to the field of surface water ecological investigation, and in particular relates to a device that can quantitatively collect submerged plants in surface water bodies such as lakes, rivers and reservoirs. Background technique [0002] Macro aquatic plants are ecological groups, which can be divided into emergent plants, floating-leaf plants and submerged plants according to their life forms. Macro aquatic plants are an important part of aquatic ecosystems. They not only serve as primary producers to provide food sources for other aquatic organisms, but also play a very important role in maintaining the ecological balance of water bodies and enhancing their self-purification capabilities. Submerged plant coverage is one of the important indicators of water ecological health assessment and assessment. At present, the main method to obtain this indicator is to set sampling points in the water body, and then use specific sampling tool...
