Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.

As shown in fig. 1, an embodiment of the present invention provides a simple water quality testing and sampling device, which includes a sampling barrel 10 and a pull rope 20.

The bottom of sampling bucket 10 is equipped with water inlet 11 and outlet 12, is equipped with into water check valve 13 in the water inlet 11, is equipped with drainage ooff valve 14 in the outlet 12, and the top of sampling bucket 10 is equipped with backup pad 15, and sampling bucket 10 is internal adaptation has piston 16, and compression spring 17 supports between piston 16 and the backup pad 15.

The pull cord 20 includes a sleeve 21 and a core 22, where the sleeve 21 may be a plastic tube and the core 22 may be a steel wire. The lower end of the sleeve 21 is fixed on the upper side of the support plate 15, the core wire 22 passes through the sleeve 21, and the lower end of the core wire 22 passes through the support plate 15 and the compression spring 17 in sequence and then is connected with the piston 16.

When water is taken, the sampling barrel 10 is placed to a position needing sampling in water through the pull rope 20, then the core wire 22 is pulled, the sleeve 21 of the pull rope 20 and the core wire 22 move relatively, the core wire 22 can pull the piston 16 in the sampling barrel 10 to move upwards, at the moment, a water sample is sucked into the sampling barrel 10 through the water inlet one-way valve 13, the compression spring 17 is compressed, the water sample can only enter and cannot exit, after sampling is completed, the pull rope is released, the sampling barrel 10 is hung to the shore, the ship or the bridge through the pull rope 20, after the sampling barrel 10 is hung to the shore, the ship or the bridge, the drainage switch valve 14 is opened, and the compression spring 17 extrudes the piston 16 downwards, so that the water sample in the sampling barrel 10 is extruded, and the water quality sampling work is completed. Therefore, adopt above-mentioned equipment, be convenient for carry out the ration sample to the quality of water of the different degree of depth, and simple structure, convenient operation.

Preferably, the upper part of the sampling bucket 10 is tapered, and the maximum water intake of the sampling bucket 10 is that the piston 16 abuts against the lower side of the tapered part. Moreover, the cone-shaped upper barrel wall of the sampling barrel 10 is provided with a communication port 18, and when the piston 16 moves upwards to absorb water, water vapor on the upper side of the piston 16 can be discharged through the communication port 18, so that the piston 16 is ensured not to be blocked to move upwards.

As a further improvement of the above scheme, the present embodiment further includes a fixing bracket 30, the fixing bracket 30 is fixed to a bank, a ship or a bridge, the fixing bracket 30 includes a connecting plate 31, a large wheel seat 32 fixed to a lower side of the connecting plate 31, a large winding wheel 33 installed on the large wheel seat 32, a small wheel seat 34 fixed to an upper side of the connecting plate 31, and a small winding wheel 35 installed on the small wheel seat 34, the sleeve 21 is wound on the large winding wheel 33, an upper end of the sleeve 21 is connected below the supporting plate 15, and an upper end of the core wire 22 passes through the supporting plate 15 and is connected to the small winding wheel 35.

When carrying out water sampling, fix fixed bolster 30 on bank, ship or bridge, the accessible rotates big rolling wheel 33 and receive and releases stay cord 20 in order to go up and down to sample bucket 10 to still can pull heart yearn 22 through rotating little rolling wheel 35 and move the absorption on driving piston 16, make water quality testing personnel easy and simple to handle and labour saving and time saving when carrying out water sampling, alleviate water quality testing personnel's the work degree of difficulty, and can avoid taking off the hand because of the accident and lead to the sample bucket 10 to sink and lose. In order to rotate the large winding wheel 33 and the small winding wheel 35, a crank (not shown in the figure) is connected to the side end of each of the large winding wheel 33 and the small winding wheel 35.

As a specific example, the back side of the fixing bracket 30 is provided with the back plate 36, the back side of the back plate 36 is provided with the hook 37, and when the fixing bracket 30 is installed, the hook 37 can be directly hung on a railing of a bank, a ship or a bridge, so that the installation is convenient.
