Detailed Description
Example 1
The utility model provides a deep well depth-fixing water sampling device which comprises a filtering sleeve, a cover body, a sampling shell and a lifting structure.
The filter sleeve 5 is provided with a filter hole 6.
The upper end and the lower end of the sampling tube 7 are closed, a limiting bulge 9 is arranged on the sampling tube 7 in a protruding mode, a water inlet and outlet through hole A10 is formed in the lower end position of the limiting bulge 9 on the sampling tube 7, the lower end of the sampling tube 7 is fixedly connected with the counterweight ball 8, and threads are arranged on the inner side of the upper end of the sampling tube 7.
The lower end of the lifting head 1 is connected with the lifting rod 2, the length of the lifting rod 2 is longer, the lower end of the lifting rod 2 is connected with the piston tube 11, the upper end of the piston tube 11 is closed, the lower end is open, the piston tube 11 is provided with limiting holes 12, the number of the limiting holes 12 is four and two by two, the inner sides of the limiting holes 12 are in contact with the blocking balls 15, the number of the blocking balls 15 is the same as the number of the limiting holes 12, the two blocking balls 15 are connected through springs 16, water inlet and outlet through holes B13 are formed in the piston tube 11, and the number of the water inlet and outlet through holes B13 is multiple.
The sample tube cover 4 is provided with threads, the upper end of the sample tube cover 4 is connected with the extension tube 3, the lower end of the sample tube cover 4 is provided with a rubber plug 14, and a through hole which is convenient for the pull rod 2 to pass through is arranged in the middle of the rubber plug 14.
Example 2
When the utility model is used, the initial position of the plugging balls 15 close to the upper group is positioned at the water inlet and outlet through hole A10, and the plugging balls 15 can be pushed to two ends due to the elasticity of the springs 16, so that the plugging balls 15 can protrude out of the limiting holes 12 and plug the water inlet and outlet through hole A10, and the elasticity of the springs 16 can offset the pressure of water on the plugging balls 15, so that the water can be prevented from entering the containing tube 7 too early when the device is immersed into a deep well. The internal diameter of the upper opening and the lower opening of the filter sleeve 5 are the same as the external diameter of the sampling tube 7, the filter sleeve 5 can be effectively fixed outside the sampling tube 7 through friction, the structure of the filter sleeve 5 is expanded outwards, the area of the water inlet of the device is increased by the filter holes 6, and water can be simply filtered, so that the large-block impurities can be prevented from blocking the water inlet and outlet through holes A when the device is immersed, and when the large-block impurities block a part of the filter holes 6, the rest of the filter holes 6 still can enable the water to enter the device to complete sampling.
The operator binds the stay cord on the pull head 1, sinks the device into the deep well groundwater suitable position, and when needs sample, the operator rapidly upwards pulls the stay cord, because counter weight ball 8 and appearance pipe 7 self inertia, appearance pipe 7 can not follow upward movement. The lifting head 1 drives the lifting rod 2 and the piston tube 11 to move upwards, and further drives the upper group of blocking balls 15 and springs 16 to deviate from the water inlet and outlet through holes A10, and move upwards, at this time, water can enter the containing tube 7 through the water inlet and outlet through holes A10, and can enter the containing tube 7 faster through the water inlet and outlet through holes B13 on the piston tube 11 and the open opening at the lower end of the piston tube 11. When the movement brought by lifting is more, the blocking balls 15 close to the upper group can enter the limiting bulge 9 and are temporarily blocked by the elastic force of the springs 16 pushing to the two sides, so that the piston tube 11 is prevented from being moved too much by lifting once, and the water inlet and outlet through hole A10 is blocked again by the blocking balls 15 and the springs 16 close to the lower group.
When the sampling is enough, the operator rapidly lifts the pull rope again, so that the piston tube 11 moves upwards again, the two groups of blocking balls 15 and the springs 16 move upwards, the upper group of blocking balls 15 are separated from the limiting boss 9, the lower group of blocking balls 15 are clamped into the water inlet and outlet through hole A10 after moving upwards, and the water inlet and outlet through hole A10 is effectively blocked through the elasticity of the springs 16, so that water cannot enter the containing tube 7 again. The pull head 1 is slowly lifted upwards, the device is lifted out of the water surface, and sampling is completed.
Example 3
When the sampling in the sampling tube 7 is required to be discharged, an operator takes down the filter sleeve 5 from the outside of the sampling tube 7, presses the lifting head 1, pushes down the piston tube 11, so that the plugging ball 15 is separated from the water inlet and outlet through hole A10, and a water sample can flow into the detection container from the water inlet and outlet through hole A10.
Because impurities may exist in the groundwater, the components in the device are affected to some extent, and therefore the interior of the device needs to be cleaned. The sample tube cover 4 is rotated to remove the sample tube cover 4 and the rubber stopper 14, and at this time, the piston tube 11 can be taken out of the sample tube 7, and an operator can clean, dry and store the components of the device for the next use.
