Detailed Description
The technical scheme of the patent is further described in detail below with reference to the specific embodiments:
example 1
Referring to fig. 1-5, a slowly sinking baffle type surface water sampler comprises an upper cover 1 and a lower cover 8 which is detachably and hermetically connected with the upper cover 1, wherein a pull rope 11 is connected to the top of the upper cover 1, a floating ball 10 is fixed on the pull rope 11, two symmetrically arranged sampling bottles 2 are fixedly arranged in the lower cover 8, and the sampling bottles 2 are used for filling and storing seawater to be sampled. The bottom of the lower cover 8 is provided with a water inlet hole 14, and seawater can enter the lower cover 8 upwards through the water inlet hole 14 and finally enter the sampling bottle 2 to be collected.
The bottom fixed mounting has two arc iron sheet 3 in the lower cover 8, and the lower cover 8 bottom is fixed with support 15, and the support 15 of setting plays the overhead effect to slowly sinking the subassembly, avoids slowly sinking the subassembly contact ground, wears to establish on the support 15 and is fixed with the metal pole 7 that runs through arc iron sheet 3 and extend to the inside of lower cover 8, and the threaded connection cover is equipped with nut 6 on the metal pole 7, and the lower cover 8 bottom is equipped with and slowly sinks the subassembly with the vertical correspondence of inlet opening 14, and when slowly sinking the subassembly and immersing in the sea water, slowly sink the subassembly and receive the ascending buoyancy of sea water, its upper surface can be laminated with support 15 support, realizes sealedly.
The metal rod 7 movably penetrates through the slow sinking assembly, the bottom end of the metal rod 7 is fixedly provided with a fixed bottom block 4, the top of the upper cover 1 is communicated with and provided with a metal shell 19, two one-way check valves 9 are fixedly arranged in the metal shell 19, and the side wall of the metal shell 19 is provided with an exhaust hole 12 transversely corresponding to the one-way check valves 9. In order to prevent the impact force generated by the direct contact of the unidirectional check valve 9 with seawater from damaging the valve clack of the unidirectional check valve 9 when the unidirectional check valve 9 is lowered, the metal shell 19 plays a good role in protecting, the exhaust hole 12 is arranged to facilitate the discharge of the air inside the device when the sampling is performed, the slow sinking component comprises a foaming material 17 and two layers of organic glass 13 with smaller density, which are respectively attached and fixed on the upper surface and the lower surface of the foaming material 17, a counterweight ring 5 positioned between the nut 6 and the arc-shaped iron sheet 3 is sleeved on the metal rod 7, and the slow sinking component is adjusted to a slow sinking state by adding the number of the heavy rings 5.
Preparation before use: firstly, two 500ml sampling bottles 2 are put into a lower cover 8 of the water sampler for internal fixation, an upper cover 1 is covered, and the connection fixation of the upper cover 1 and the lower cover 8 is realized.
The throwing process comprises the following steps: when the device is thrown, the device can freely fall into the sea, in the process of sinking into the sea, the slowly sinking component can firstly contact the sea, the upper cover 1 and the lower cover 8 are made of stainless steel materials and have heavier weight because the buoyancy is larger and can temporarily suspend on the sea, and the slowly sinking component can sink at a faster speed after contacting the sea. The sinking speed difference of the two components enables the sinking component to cling to the bottom of the bracket 15 and block the water inlet 14 in the sinking process, so that seawater cannot enter the lower cover 8. In the sinking process, seawater can enter the outer side of the one-way check valve 9 from the exhaust hole of the upper cover 1, the one-way check valve 9 is in a closed state under the combined action of gravity and external water pressure, and the seawater cannot enter the lower cover 8.
The water collection process comprises the following steps: due to the buoyancy force of the sea surface floating ball 10, the device stops sinking after sinking to a depth of about 0.5 meter, and the slowly sinking component continues sinking for a certain distance due to the slowly sinking state. After the water inlet hole 14 loses the shielding of the slow sinking component, seawater can flow into the lower cover 8 from the water inlet hole 14 due to the action of water pressure, the two sampling bottles 2 are slowly filled, air in the sampling bottles 2 is extruded to the lower cover 8 by the seawater, passes through the one-way check valve 9 and is discharged through the air outlet hole 12, and at the moment, the water surface can be turned over.
The recovery process comprises the following steps: when the turning of the water surface is finished, the water collection is finished, namely, the pulling rope 11 in the handle is retracted. The unidirectional check valve 9 is closed again under the action of gravity and inertia in the ascending process of the device, so that seawater in other layers is prevented from entering; the slow sinking component keeps the original open state in the ascending process, namely, the slow sinking component is separated from the water inlet 14, the redundant seawater in the device is gradually discharged under the action of gravity and inertia, and after the device is lifted above the water surface, only the seawater is reserved in the two sampling bottles 2, and the redundant seawater flows out through the water inlet, so that the water collection is completed.
Example 2
On the basis of embodiment 1, the slowly sinking component can be replaced by a weight box 16, the bottom of the weight box 16 is connected with a bottom cover 18 in a threaded manner, before water collection, the bottom cover 18 is rotated to separate from the weight box 16, and a balancing weight with proper weight can be added into the weight box 16, so that the slowly sinking effect of the device entering the weight box 16 in the seawater process is realized.
Further, the diameter of the slowly sinking component is larger than that of the water inlet hole 14, so that the slowly sinking component can better shield the water inlet hole 14, and seawater with non-water-sampling depth does not enter the lower cover 8 in the initial sinking stage of the device.
Further, the unidirectional check valve 9 forms an inclined included angle of 45 degrees with the horizontal plane, and when the device is released into seawater vertically, the valve clack of the unidirectional check valve 9 is closed by self gravity to prevent the seawater from flowing in.
In summary, the upper cover 1, the lower cover 8, the pull rope 11, the floating ball 10 and the like in the device are direct applications of the prior art means, and the specific connection structure and the position relationship of the sinking component, the water inlet 14, the one-way check valve 9 and the like in the technical scheme are innovation points of the invention, and the invention can collect two bottles of water samples at the same time, so that the parallelism of the parallel samples is greatly improved, and the sampling efficiency is also improved; the whole sampling process only needs to throw the water sampler into water, and unnecessary operations such as pulling out a release pin are not needed, so that the operation is greatly simplified, the learning cost of use is reduced, and the sampling work efficiency is improved.
