Detailed Description
The embodiments of the present invention will be further explained with reference to the drawings.
Referring to fig. 1 and 2, a multifunctional automatic-feeding type parallel water sample sampler comprises a counterweight lead block 1, a buoy 2, a rope buckle 3, a sampling bottle 4, a metal fixing ring 5, a movable bottle cap 6, a fixed hauling rope 7 and an upper lifting rope 8; a lower lifting rope 9 is arranged on the top surface of the counterweight lead block 1, a through sliding hole 201 is formed in the center of the buoy 2, and the lower lifting rope 9 penetrates through the sliding hole 201 to be connected with the rope buckle 3; the two sampling bottles 4 are symmetrically fixed on two sides of the counterweight lead block 1 through the two metal fixing rings 5 respectively, the movable bottle caps 6 are buckled right above the sampling bottles 4 and are hung at the bottom of the floating barrel 2 through the fixed hauling ropes 7; the upper lifting rope 8 is hung on the rope buckle 3.
The buoy 2 is of an ellipsoid structure, the long axis of the buoy is 40cm, and the short axis of the buoy is 25 mm; the slide hole 201 is formed along the minor axis direction of the buoy 2, when the buoy 2 is in contact with the water surface, the contact area of the buoy 2 and the water surface is large, and meanwhile, the floating stability of the buoy 2 can be guaranteed.
The upper lifting rope 8 is a nylon rope with the length of 20m and the diameter of 3cm, has high strength, and can prevent the situation that the sampler falls into water and is lost due to the breakage of the upper lifting rope 8.
The length of the lower lifting rope 9 is 50cm, the length of the fixed hauling rope 7 is 45cm, the two function effects are realized, when the sampling bottle 4 is 50cm below the water surface, the buoyancy of the floating barrel 2 is just driven by the fixed hauling rope 7 to move towards the position right above the sampling bottle 4, so that the flat mouth of the sampling bottle 4 is opened.
The density of the movable bottle cap 6 is larger than the density of water, so that the movable bottle cap 6 can sink under water.
The surface of the metal fixing ring 5 is subjected to rust prevention treatment, so that the fixed metal ring 5 is prevented from rusting after being used for a long time.
The 4 central lines of bottle with 1 central line of counter weight lead for sampling bottle 4 is when underwater, and the central line is in vertical plane all the time, so that two time sampling bottle 4 can move about the water sample of the same degree of depth.
The fixed traction rope 7 and the suspension point of the buoy 2 are collinear with the central line of the sampling bottle 4, so that the movable bottle cap 6 is completely positioned right above the sampling bottle 4.
The using method comprises the following steps: carry water detecting instrument to waiting to take a sample the scene, carry down lifting rope 9 and slowly with 1 below of counter weight lead block, at this moment, counter weight lead block 1 sinks and drives both sides sampling bottle 4 sinks, at the in-process that sinks, increases along with water pressure, activity bottle lid 6 with 4 locks of sampling bottle become tight gradually, when reaching the 50cm degree of depth, because under the gravity of counter weight lead block 1 and the 2 buoyancy of flotation pontoon effect, fixed haulage rope 7 drives activity bottle lid 6 follows the 4 bottleneck of sampling bottle breaks away from to begin to sample the water of 50cm degree of depth, at last, through dragging last lifting rope 8, will counter weight lead block 1 and sampling bottle 4 take out the parallel sample sampling in order to accomplish the water sample.
The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the content of the present invention or the direct or indirect application attached to the technical field of other related products are included in the patent protection scope of the present invention.
