Description
Technical Field
The utility model belongs to water sampling instrument field, especially a location water sample water sampler of inside vacuum design is applied to and takes the water sample for analysis to predetermined water layer.
Background
The water sampling work is an important content of water environment protection and water environment scientific research, and the collection of water samples with different depths, particularly the collection of positioning layered water samples, becomes a premise and a basis for carrying out various water resource research works.
At present, various commercial positioning water sample samplers (or devices) have been developed and developed, which can collect layered water samples with different requirements. The layered water sample sampler is mainly divided into two categories, wherein one category is mainly designed for marine scientific research work, needs a special ship to provide a power supply and hoisting equipment, and has the characteristics of complex structure and high operation difficulty; the sampler is suitable for inland water bodies such as rivers, lakes and reservoirs and the like, is convenient to operate, but when the sampler samples water in a preset layer, the sampling efficiency of sampling personnel is directly influenced due to the fact that the operation steps are complex.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the shortcomings of the prior art and provide a positioning water sample collector with simple and convenient operation, low material cost and wide application range and designed by internal vacuum.
The utility model discloses realize the technical scheme of purpose as follows:
The utility model provides a location water sample hydrophore of inside vacuum design which characterized in that: the sampling device comprises a cylindrical sampling cylinder body, a handle, a traction rope, a gas conduit, a one-way check valve, a floating plate and a pulley, wherein the gas conduit is fixedly arranged at the top of the sampling cylinder body, the one-way check valve is fixedly arranged at the lower part of the side surface of the sampling cylinder body, a balancing weight is embedded in the bottom of the cylinder body, the handle is fixedly arranged at the middle upper part of the side surface of the cylinder body, the traction rope is fixedly arranged at the top of the handle, the pulley is fixedly arranged at the top of the floating plate, the traction rope penetrates through the pulley.
Wherein the whole sampling cylinder body should keep enough air tightness.
Wherein, the balancing weight should ensure that the sampling barrel can sink fast after entering water.
Wherein, the check valve can only feed water.
Wherein, sufficient leakproofness should be guaranteed with sampling barrel top junction to the gas conduit, and the accessible conduit fills, the gassing to the sampling barrel under the supplementary external instrument.
Wherein, the haulage rope is printed with the water depth mark for recording the water depth.
The utility model has the advantages that:
1. The utility model provides a single check valve is adorned admittedly to the well lower part of water sampler for the water sample only can get into the sampling barrel from the sampling barrel outside, has avoided the loss of water sample in the sampling barrel in the sampling process.
2. The utility model provides a bottom of hydrophone barrel is adorned a base admittedly under, installs the pouring weight in the base, and the pouring weight is installed inside the base, not only is difficult to drop, receives the difficult rust of protection of barrel material moreover.
3. The utility model discloses utilize the slide wheel to realize the control that the sampling barrel goes up and down on the kickboard, be printed on the haulage rope and have the water depth mark, through observing the mark, can make the sampling personnel more simple and convenient, laborsaving collection to the water sample of predetermined water layer, it is very convenient to operate.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments, which are illustrative, not restrictive, and the scope of the invention should not be limited thereto.
A positioning water sample sampler with an internal vacuum design comprises a cylindrical sampling cylinder body, a handle, a traction rope, a gas conduit, a one-way check valve, a floating plate and a pulley, wherein the gas conduit 4 is fixedly arranged at the top of the sampling cylinder body, the one-way check valve 6 is fixedly arranged at the middle lower part of the side surface of the sampling cylinder body, a balancing weight 7 is embedded in the bottom of the cylinder body, the handle 3 is fixedly arranged at the middle upper part of the side surface of the cylinder body, the traction rope is fixedly arranged at the top of the handle, the pulley 2 is fixedly arranged on the floating plate 1, the traction rope penetrates through the pulley, and the traction rope 5 can.
The working principle of the water sampler is as follows:
The water sampler is used for collecting a water sample for analysis on a preset water layer, when the sampling cylinder body is not required to be communicated with an external water body, gas can be filled into the sampling cylinder body under the assistance of an external instrument through the gas conduit, and the pressure in the sampling cylinder body is higher than the pressure outside the sampling cylinder body, so that the water sample cannot enter the sampling cylinder body at the moment. When needs sampling barrel and external water intercommunication, through the gas conduit, can discharge sampling barrel internal gas gradually under the external instrument is supplementary, reach vacuum state until the bucket in, be "negative pressure" state in the sampling barrel this moment, the water sample can get into sampling barrel through one-way check valve rapidly, until being full of sampling barrel.
The working process of the water sampler is as follows:
Before the sampling cylinder body is placed into a water body, gas is filled into the sampling cylinder body through a gas guide pipe under the assistance of an external instrument, the cylinder body is placed into water and continuously inflated, the cylinder body sinks under the action of a bottom weight, after the cylinder body reaches a preset depth, a lifting rope on a handle is fixed, the position of the cylinder body is kept unchanged, inflation is stopped, air suction is gradually changed under the assistance of the external instrument, a water sample enters the sampling cylinder body through a one-way check valve under the action of the pressure of an external water body, the sampling cylinder body is communicated with the water body at the moment, and the water sample enters the cylinder body. Because the design of the one-way check valve is adopted, the worry about water sample leakage is not needed. After sampling, the pulley is utilized to lift the sampling cylinder to the water surface floating plate through the traction rope, and the sampling is finished.
