Description

Portable Depth and Distance Water Sample Collection Device

technical field

The utility model relates to a water sample collection device, in particular to a remote water sample collection device with a fixed depth and a fixed distance using a telescopic sleeve.

Background technique

When many departments such as environment and health conduct water quality analysis or aquatic biological analysis to understand water conditions, they need to first complete the collection of representative water samples. In the vertical direction, it is generally stipulated that the water depth is 0.5m, but there is still a requirement that water can be drawn at any water depth in the research. Horizontally, for small rivers, it is required to take water samples at the center line of the river; for large rivers, it is required to take water samples at the center line and the riverside lines on both sides.

There are two main methods of water extraction:

The first water intake method is to collect water samples in deeper water and farther away from the shore by dropping water collectors from ships. However, this method requires high costs and is difficult to implement in rivers where some ships are inconvenient. Generally, water samples are collected through water structures such as bridges, etc., but there is no such convenient condition for rivers without bridges or wild suburban rivers.

The second method of water intake is to collect water samples by manually throwing water collectors, but this method is difficult to guarantee in terms of accuracy and safety.

At the same time, the above two methods have the problems of poor airtightness of the equipment and the inability of the shape and size of the equipment to adapt to various external environments.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies in the prior art, and provide a high-efficiency, low-cost, convenient and flexible within a certain range, portable depth and fixed water sample collection at any water depth and any shore distance. away from the water sample collection device.

In order to solve the above technical problems, the utility model is realized through the following technical solutions:

A portable fixed-depth and fixed-distance water sample collection device is characterized in that: it includes a telescopic sleeve, the lower end of the telescopic sleeve is fixed by a bracket, the lower side of each joint of the telescopic sleeve is provided with a collar, and the water pipes pass through each collar. Pass through, one end of the water pipe is provided with a water suction head and a dead weight, and the other end is connected to a water sample bottle, and the water sample bottle is connected to the suction port of the battery micro vacuum pump through a suction pipe.

The suction pipe of the water sample bottle first passes through the buffer bottle and then connects with the storage battery miniature vacuum pump.

The water pipe has scales on it.

Compared with the prior art, the beneficial effects of the utility model are:

The telescopic sleeve is used to extend along the width of the river, so that people can complete the water sample collection at the middle line of the river by standing on the bank. The water sample bottle is placed on the bank to collect the water sample drawn by the water pipe fixed on the telescopic sleeve. In this way, excessive demands on the mass and rigidity of the telescopic sleeve are avoided. It is extremely convenient to carry and easy to operate. To a certain extent, the automatic collection of water samples can be realized. In particular, it can realize convenient and safe water sample collection at the central line of the river, which is more meaningful.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail:

As shown in Figure 1, the utility model consists of a dead weight 1, a telescopic sleeve 2, a collar 9, a support 11, a water pipe 3, a water drawing head 8, a scale 10, a water sample bottle 4, a buffer bottle 5, a battery miniature vacuum pump 6, Device case 7, battery 12, rubber stopper 13, fixed ring 14 form. There is a collar 9 on every joint telescopic sleeve 2, and it is supported by a support 11 when it needs to be fixed. The front end of the water pipe 3 with scale is connected with a grille-type drawing water head 8, on which eye-catching scales 10 are arranged at regular intervals. During non-working state, each part structure is all placed in the device case 7 by respective positions. During work, the dead weight 1 is connected to the water pipe 3 to drive the water pipe into the water to ensure that the water drawing head 8 does not shake with the water flow, and the water depth of the sampling place is displayed by the marked line on the water pipe. The water pipe 3 is fixed on the telescopic sleeve 2 through the collar 9 and the fixed ring 14, and any bank-side distance can be realized through the adjustment of the length of the telescopic sleeve, mainly for the collection of water samples at the middle line of the river. Water pipe 3 links to each other with water sample bottle 4 to obtain water sample simultaneously, then connects buffer bottle 5 again, avoids water sample from entering in the water pump, finally connects the storage battery type miniature vacuum pump 6 that is connected with battery 12, drives whole device work by water pump. After determining the length of the telescopic sleeve, fix the water pipe with the holding weight, consider the length of the telescopic sleeve and the water depth to determine the length of the water pipe, complete the connection, turn on the water pump, start water intake, turn off the water pump, and end water intake.

The unexplained parts involved in the utility model are the same as the prior art or are realized by adopting the prior art.
