Problems solved by technology

[0003] The sample collection equipment used for water conservancy testing in the prior art needs to go deep into the water for sampling when collecting samples. When the water level is deep, it needs to take multiple and layered samples. The existing collection device can only collect one sample at a time. For the sample liquid, repeated sampling is required for waters of different depths. The workload of the staff is large, and the sampling operation of the existing equipment is complicated. After one sampling is completed, the sampling bottle needs to be taken out and refilled. , thus reducing the sampling efficiency

Embodiment 1

[0037] Such as Figure 1-Figure 11As shown, a sample collection device for water conservancy testing according to an embodiment of the present invention includes a first simplified body 1, a second simplified body 2 is fixedly connected to the inner bottom wall of the first cylindrical body 1, and a second simplified body 2 is fixed to the inner bottom wall of the first simplified body 1. The top is rotatably connected with the first rotary rod 3 through the bearing, the bottom end of the first rotary rod 3 is inserted into the inside of the first simplified body 1, and the bottom end of the first rotary rod 3 is fixedly connected with the first block 6. The bottom of the first block 6 is fixedly connected with the second rotating rod 4, the bottom end of the second rotating rod 4 is fixedly connected with the second block 7, and the bottom of the second block 7 is fixedly connected There is a third rotating rod 5, the inner side wall of the first simplified body 1 is fixedly ...

Embodiment 2

[0040] Such as figure 1 As shown, the difference between this embodiment and Embodiment 1 is that the bottom of the first simplified body 1 is fixedly connected with two fixed blocks 33, and the two fixed blocks 33 are symmetrically distributed, and the fixed blocks 33 The bottom is fixedly connected with a hook 34 , the inner top wall of the hook 34 is hinged with a stopper 35 through a torsion spring, and the bottom of the stopper 35 is attached to the inner bottom wall of the hook 34 .

[0041] By adopting the above-mentioned technical scheme, before the first simple body 1 sinks into the bottom of the water, hang the counterweights of different weights on the hook 34 as required, and the stopper 35 fixes the counterweights on the inside of the hook 34 to prevent the counterweights from Get off the hook 34.

Embodiment 3

[0043] Such as Figure 12 As shown, the difference between this embodiment and Embodiment 2 is that a threaded portion 38 is provided on the outside of the conduit 14, and a threaded hole 39 matching the threaded portion 38 is opened inside the bottle mouth 36, so Said conduit 14 is threadedly connected to the inside of the bottle mouth 36 .

[0044] By adopting the above-mentioned technical scheme, the conduit 14 is threadedly connected to the inside of the sampling bottle 15 or the backup bottle 16, and the connection or separation with the conduit 14 is realized by rotating the sampling bottle 15 or the backup bottle 16, and the disassembly is simple and convenient.

Abstract

The invention discloses sample collection equipment for water conservancy detection, which comprises a first cylinder, the inner bottom wall of the first cylinder is fixedly connected with a second cylinder, the top of the first cylinder is rotatably connected with a first rotating rod through a bearing, and the bottom end of the first rotating rod is inserted into the first cylinder. The bottom end of the first rotating rod is fixedly connected with a first block body, and the bottom of the first block body is fixedly connected with a second rotating rod. According to the equipment, water areas with different depths can be sampled at the same time according to needs, sampling of the sampling bottles with different depths is controlled by rotating the rotary knob, operation is easy and convenient, the repeated sampling process for sampling the water areas with different depths is omitted, the sampling frequency of workers is reduced, and the task intensity of the workers is reduced.

Description

technical field [0001] The invention relates to the technical field of water conservancy detection, in particular to a sample collection device for water conservancy detection. Background technique [0002] Water conservancy project is a project built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and rejuvenating profits. An important pillar of economic development, when monitoring hydrology, special testing equipment is required. [0003] The sample collection equipment used for water conservancy testing in the prior art needs to go deep into the water for sampling when collecting samples. When the water level is deep, it needs to take multiple and layered samples. The existing collection device can only collect one sample at a time. For the sample liquid, repeated sampling is required for waters of different depths. The workload of the staff is large, and the sampling operation of the existing equipment is complic...
