Technical field
The utility model is related to field of environment engineering technology more particularly to a kind of device for fetching water with check valve.
Background technology
Body eutrophication improvement has become world today's property problem.Various countries successively carry out it since the 1960s
Numerous studies, and propose corresponding countermeasure and measure, it includes mainly the following to be summed up, and is subtracted first, improving overall situation
The exogenous pollution object of water body is inputted less, second is that transalkylation effluent discharge and dilution diffusion, third, regulation and control are rinsed compared with clean water, fourth,
It dredges and waits hydraulic engineerings measure, fifth, chemical measure, sixth, biological control measure, seventh, Local Artificial ecological systems engineering etc..For
Environmental project person, people often carry out quality testing to water source, will not set large-scale detection when carrying out Water quality detection
It is standby to take scene to, it is sampled often through water body, then takes back laboratory and be detected and obtain a result, due to each position in river
Water velocity it is inconsistent, it is simple a position carry out water body sample detecting the water body in entire river can not be carried out it is fine
Judgement, although can be sampled in the prior art to the water body of different depth, due to the impurity in water body so that extraction
The poor sealing of device, when extraction element is higher than the water surface, the water body being drawn into extraction element flows out outward so that really
It is seldom into the water body in collection device, influence entire sampling progress.
Utility model content
The purpose of this utility model is to provide a kind of water body collectors with drip-preventing function, mainly solve the prior art
Present in extraction element poor sealing, lead to the water body to be measured outflow of extraction, the problem of influencing sampling progress.
To achieve the goals above, the technical solution adopted in the utility model is as follows：
A kind of device for fetching water with check valve, includes the cylinder for water intaking, be opened in cylinder body bottom for water inlet diversion
Slot, the pull rod being nested in the middle part of the cylinder top in cylinder are nested in pull rod bottom and the multilayer that is in close contact with cylinder inboard wall
Piston is fixed on the telescopic rod being made of at the top of cylinder and more piece, be nested with outside telescopic rod and be fixedly connected at the top of pull rod
Cross bar is fixed on telescopic rod upper end and the lifting device for raising rod, and the ring cylinder on cylinder body outer wall one week, rotation is arranged
Check valve on drinking trough；Wherein, ring cylinder includes several copper beads for making cylinder sink, and is adopted between telescopic rod two adjacent sections
It is fixed with bayonet lock mode, and telescopic rod indicates continuous scale from bottom to top.
Further, the lifting device includes the axis for being fixed on telescopic rod upper end and being mutually parallel with cross bar, inner ring
The bearing being fixed on axis, the disk being fixed on bearing outer ring, the arc groove being opened on disk, one ends wound is in arc
In slot and the other end is fixed on the drawstring on cross bar, and the handle being arranged on disk.
Specifically, the pull rod bottom is equipped with the fixing piece for fixing multilayer piston.
Compared with prior art, the utility model has the advantages that：
(1) sampler of the utility model setting by outside cylinder the fixed ring cylinder for being built-in with several copper beads keep it heavy
Enter in water, then the length of adjustable telescopic rod holds telescopic rod to reach water level needed for test, by lifting device by cross bar and
Pull rod pulls up, and tests required water body by check valve through entering in cylinder at gutter, is unidirectionally led since check valve has
Logical effect avoids the water body extracted in cylinder and outbound flows, then detached check valve with drinking trough by rotating, then by cylinder
Internal water body is squeezed into test device, greatly improves sample rate in this way.
(2) axis is connect by the lifting device of the utility model by bearing with disk, and bearing rotation reduces frictional force,
It promotes speed faster, is conducive to piston and is lifted up, the convenient sampling to water body.
(3) the utility model telescopic rod two adjacent sections can fix, and the scale being arranged thereon is sequentially increased from bottom to top,
Different depth, different location water body can be sampled, and need not additionally use survey tool, operation is more simple and fast.

Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and examples, and the embodiment of the utility model includes
But it is not limited to the following example.
Embodiment
As shown in Figure 1, a kind of device for fetching water with check valve, includes the cylinder 1 for water intaking, it is opened in 1 bottom of cylinder use
In the gutter 2 of water inlet, the pull rod 3 in cylinder 1 is nested in from 1 top middle portion of cylinder, be nested with 3 bottom of pull rod and with cylinder 1
The multilayer piston 4 that inner wall is in close contact, the telescopic rod 5 for being fixed on 1 top of cylinder and being made of more piece, is nested with outside telescopic rod 5
And the cross bar 6 being fixedly connected with 3 top of pull rod, it is fixed on 5 upper end of telescopic rod and the lifting device for raising rod 3, setting
Ring cylinder 7 on 1 outer wall of cylinder one week, the check valve 10 being rotatably mounted on drinking trough 2；Wherein, ring cylinder 7 includes several makes
The copper bead 8 that cylinder 1 sinks is fixed using bayonet lock mode between 5 two adjacent sections of telescopic rod, and the company of indicating from bottom to top of telescopic rod 5
Continuous scale.
Also, the lifting device includes the axis 11 for being fixed on 5 upper end of telescopic rod and being mutually parallel with cross bar 6, inner ring
