[Industrial applications]

 The present invention relates to an apparatus that enables easy and safe water quality sampling at a point away from a shore while inspecting water quality such as rivers and lakes.

Conventionally, in the inspection of water quality of rivers and lakes, a method of taking a sample at a point away from the shore has been to use a boat or the like to reach a sampling point and directly draw water with a bucket or the like. It was

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional method, a boat or the like must be prepared each time a sample is taken, and work on the water away from the shore is also dangerous, so climatic conditions, places, time and date restrictions, etc. There was a problem. In order to solve such conventional problems, it is an object of the present invention to provide a method for easily and safely taking a water quality sample at a point away from the shore without using a boat or the like. I am trying.

[Means for Solving the Problems]

 In this device, one end of the container is used as a liquid inlet and outlet, and the other end is an air inlet and outlet that can be opened and closed by a levitation valve, and a slit is provided to hold the sampler just by grasping it with a finger. The feature is that it has a feeder that can be used and that the recovery wire can be moved.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a perspective view showing the appearance of an embodiment of the present invention. FIG. 1 shows a state in which the sampler 1 is pulled out from the injector 2 and connected by the wire 3. First, the function of each of the sampler 1 and the injector 2 will be described, and then how the sampler 1 and the injector 2 function as a liquid sample collecting device will be described.

FIG. 2 shows the configuration of the sampler 1 and the injector 2. The sampler 1 comprises a container 4 for holding a liquid, which has one end narrowed and a liquid inlet / outlet, a levitation valve 5 rotatably attached to the packing 6, an iron piece 7 embedded in the levitation valve 5, and a magnet embedded in the packing 6. 8, a reset pin 9 for resetting the levitation valve 5, a spring 10, a weight 11 connected to the wire 3 and a protector 12 and a protector 13 made of a soft resin for ensuring safety when hitting a person or an object. It is being touched. Further, an air hole 14 is formed in the packing 6, a hole 15, a hole 16 and a hole 17 are formed in the protector 12 for allowing liquid or air to pass therethrough, and an air hole 18 is formed in the protector 13.

The injector 2 makes the main body 20 for holding the sampler 1 easy to elastically deform the main body 20, and the slit 21 used for passing the wire 3 when collecting the sampler 1 and the friction with the sampler 1. The stopper 22 made of a soft resin to make the size larger and to hold it easily, the finger hook 23 for preventing the main body 20 from being separated from the hand when the sampling device 1 is put in, the reel 24 for winding and storing the wire 3, and the reel 24 for the main body 20. Further, it is composed of a shaft 26 for rotating by the attached handle 25, and a pin 27 for folding the handle 25 except at the time of winding.

FIG. 3 shows a liquid collecting process of the collector 1. (A) The loaded sampler 1 begins to sink below the liquid surface due to the weight of the weight 11, the liquid enters the container 4 through the holes 15, 16 and 17, and the air in the container 4 is the air hole 14, Escape through vaporization 8. Eventually, the liquid level in the container 4 pushes the levitation valve 5 upward.

(B) When the distance between the iron piece 7 embedded in the levitation valve 5 and the magnet 8 embedded in the packing 6 becomes sufficiently short, the iron piece 7 is attracted by the magnetic force of the magnet 8 and the levitation valve 5 is filled with air holes in the packing 6. Close 14 The air in and out of the container 4 is blocked, and the inflow of liquid is stopped. Since the inlet / outlet of the container 4 is sufficiently small, the liquid in the container 4 will not flow out due to the dropper effect. In this state, the wire 3 is wound and the sampling device is collected.

(C) The collected sampler 1 is set upright and the reset pin 9 is pushed to push down the levitation valve 5, the air hole 14 of the packing 6 is opened, and the liquid in the container 4 is taken out as a sample through the hole 15. .

FIG. 4 shows a state in which the sampling device 1 is set in the charging device 2. (A) Insert the sampler 1 so that the weight 11 is located outside the main body 20, and put a finger through the finger rest 23. (B) By grasping the vicinity of the stopper 22, the main body 20 is elastically deformed, and the collector 1 can be firmly grasped through the friction of the stopper 22. In this state, pull the arm backwards and throw in the ball 1 by throwing the ball downward.

FIG. 5 shows a state in which the sampling device 1 is charged by using the charging device 2. At the last moment when the sampling device 1 is thrown in by throwing the ball downward, (a) the force of the finger near the stopper 22 is released, and (b) the elasticity of the body 20 causes the stopper 22 to separate from the sampling device 1 and collect. Vessel 1 pops out of thrower 2. However, the throwing device 2 does not pop out because the finger rests on the finger rest 23. The wire 3 is pulled by the sampler 1 and the wire 3 is paid out from the reel 24.

FIG. 6 shows a state in which the sampling device 1 is collected by turning the handle of the charging device 2. After the liquid of the sample is taken into the sampler 1, the wire 3 is moved through the slit 21 so as to be close to the winding axis of the reel 24, and the handle 25 is raised to wind the wire.

In this embodiment, the sampler 1 is used to insert the sampler 2 to a distant sample collection point. However, when collecting a sample on the water surface just below the bridge, a handle is required. It is also possible to slowly drop the sampling device 1 while turning to unwind the wire. The sample to be collected is not limited to water as long as it is a liquid.
