Agricultural environment-friendly detection device

Abstract

The invention discloses an agricultural environment-friendly detection device. The device comprises a box body and a base fixedly arranged at the bottom of the box body, a water sample collection unitand a first power supply are arranged on the bottom wall in the box body; a water sample storage unit and a water sample detection unit are respectively arranged in the middle of the side wall of thebox body; the water inlet end of the water sample storage unit is communicated with the water outlet end of the water sample collection unit through a main pipeline, a main controller and a first wireless signal transceiver are further arranged in the box body, and the first wireless signal transceiver and the water sample detection unit are electrically connected with the main controller. According to the invention, automatic sampling and online detection of underwater water samples at different depth levels are realized, and the detection efficiency is high; meanwhile, mutual influence between water qualities of different levels of water levels is avoided, and the accuracy and reliability of a water quality detection result are guaranteed. The device is reasonable in structure, small insize, easy to operate, convenient to carry and use and suitable for water quality sampling and detection of various water areas.

Description

technical field [0001] The invention relates to the field of agricultural testing equipment, in particular to an agricultural environmental protection testing device. Background technique [0002] The water quality of rivers, lakes, reservoirs, canals, wells and other wild waters and water sources is directly related to the yield and quality of crops in agricultural production. Especially for the vast rural areas, groundwater is mainly used as the main water source for irrigation, and even The water source is directly quoted, so it is necessary to carry out frequent testing on the wild water source. [0003] At present, the commonly used manual sampling method is used to collect water samples, and then the collected water samples are tested. However, this method usually requires inspectors to randomly sample on the shore of the water source, and cannot realize the collection of water samples at different depths in the deep waters in the middle of the waters. , so that the s...

Problems solved by technology

[0003] At present, the commonly used manual sampling method is used to collect water samples, and then the collected water samples are tested. However, this method usually requires inspectors to randomly sample on the shore of the water source, and cannot realize the collection of water samples at different depths in the deep waters in the middle of the waters. , so that the sample collection is not comprehensive enough, resulting in large errors in the test results, low accuracy and reliability, and the test personnel need to use the equipment on the water to reach the middle of the water area for sampling, which increases the difficulty of sampling, and usually needs to extract multiple samples of different depths. Handling water samples, the workload of the operator is relatively large

[0004] Some existing water quality sampling equipment has complex structures and large volumes, and is not suitable for field testing operations. It is necessary to carry water samples to the testing center for testing, which greatly reduces the testing efficiency; portable testing equipment, although it can meet the needs of field testing. It is required for detection, but the collection of water samples for detection still uses manual sampling, and the detection efficiency is not high, especially for water quality sampling operations in some narrow areas (such as wells), which is very inconvenient
