Description

A sewage sampler

technical field

The utility model relates to a vessel, in particular to a sampler.

Background technique

With the advancement of my country's industrialization process, most rivers and lakes are polluted to a certain extent. The relevant urban water affairs departments need to regularly test the water quality. Some common sewage samplers on the market now use electric pumps, which have complex structures and high production costs. , In addition, there is also the method of taking water samples in ordinary plastic bottles, which is easy to operate but inconvenient to use, and is not conducive to saving water samples. After one-time use, waste plastic bottles will cause secondary pollution to the environment.

Contents of the invention

Purpose of the invention: The purpose of this utility model is to provide a sewage sampler for the deficiencies of the prior art, which effectively solves the problems of excessive odor and easy dirty hands during the sampling process, and can record the sampling date for repeated use .

Technical solution: A sewage sampler described in the utility model includes a pumping cylinder, a piston, a connecting rod and a handle sequentially connected to the piston, the side wall of the pumping cylinder is provided with several digital rollers, and the pumping cylinder A water inlet and a water inlet valve are provided in the middle of the bottom surface, and a water outlet and a water outlet valve are provided at the edge of the bottom surface.

Preferably, the connecting rod is a telescopic rod, which is easy to carry.

Preferably, the valve port shape of the water outlet valve is adapted to the arc surface of the inner wall of the test tube, so as to facilitate sampling.

Preferably, the cover of the pumping tube is detachably installed on its upper part, and a sealing ring is provided at the connection between the cover and the connecting rod.

Preferably, both the water inlet valve and the water outlet valve are internal threaded gate valves.

Working principle: open the water inlet valve, hold the handle and pull the piston backward, the water sample enters the pumping cylinder from the water inlet, close the water inlet valve, turn the digital roller to record data, when testing, open the water outlet valve, push the handle to collect the water sample Press it out of the pumping cylinder, and the water sample flows into the test tube along the valve port of the water outlet valve.

Beneficial effects: the sewage sampler of the utility model is easy to carry and store, the sampling process is simple and convenient, and effectively solves the problems of excessive odor and easy dirty hands during the sampling process, and the digital roller can clearly record the storage time of the water sample On the sampling date, water samples can be collected quantitatively by pumping water. Since there is no electric drive device, its structure is simple and low in cost, and it can be used repeatedly.

detailed description

The technical solutions of the utility model are described in detail below, but the protection scope of the utility model is not limited to the embodiments.

As shown in Figure 1, the sewage sampler of the present utility model comprises a pumping cylinder 1, a piston 2 and a connecting rod 3 and a handle 4 which are sequentially connected with the piston 2, the connecting rod 3 is a telescopic rod, and the side wall of the pumping cylinder 1 is provided with A number of digital rollers 5, a water inlet 6 and a water inlet valve 7 are provided in the middle of the bottom surface of the pumping cylinder 1, wherein the diameter of the water inlet 6 of the barrel mouth is set to 30mm, and the edge of the bottom surface is provided with a water outlet 8 and a water outlet valve 9, and the water inlet The valve 7 and the water outlet valve 9 are both internal thread gate valves. The shape of the valve port of the water outlet valve 9 is suitable for the arc surface of the inner wall of the test tube. The diameter of the valve port of the water outlet valve 9 is 10mm. In the upper part, remove the cylinder cover when sampling, and reinstall the cylinder cover after the water sample is taken. There is a sealing ring at the connection between the cylinder cover and the connecting rod 3 to prevent water leakage. When in use, open the water inlet valve 7 and adjust the telescopic rod to The longest, pull the piston 2 backward through the handle 4, the water sample enters the pumping cylinder 1 from the water inlet 6, close the water inlet valve 7, turn the digital roller 5 to record data, the digital roller 5 can be set to four groups, and the digital roller 5 Marked with numbers 0-9, two of which are used to record the month, and two are used to record the date. When sampling, open the water outlet valve 9, push the water sample into the pumping cylinder 1 through the handle 4, and the valve port of the water outlet valve 9 is pasted. Close the side wall of the test tube, and compress the telescopic rod to the shortest point. The water sample fits the valve port of the water outlet valve 9 and flows into the test tube. The sewage sampler with the remaining water sample is placed in the refrigerator for storage.

As stated above, although the invention has been shown and described with reference to certain preferred embodiments, this should not be construed as limiting the invention itself. Various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
