[0028] Example 1

[0029] A sealed storage device for river water quality safety testing, such as Figure 1-4 As shown, it includes a water suction pipe 1, a limiting ring 2, a limiting column 3, a water inlet pipe 4, a ball valve 5, a collecting bucket 6, a water suction mechanism 7 and an adjusting mechanism 8. A limiting ring 2 is slidably provided in the limiting column 3, the water suction pipe 1 is installed in the limiting ring 2, the water inlet pipe 4 is installed on the front side of the water suction pipe 1 by means of bolts, the water inlet pipe 4 is a hose, the water inlet pipe 4 is located on the limiting column 3, the water inlet pipe 4 is rotatably connected with a ball valve 5, the ball valve 5 is opened with a through hole, the collecting bucket 6 is installed on the front side of the limiting column 3, a water suction mechanism 7 is provided between the left and right sides of the limiting column 3, an adjusting mechanism 8 is provided in the limiting column 3, the adjusting mechanism 8 is connected to the limiting ring 2 by means of threads, and the adjusting mechanism 8 is connected to the water suction mechanism 7 by means of threads.

[0030] When it is necessary to collect and seal the river water for subsequent testing, the device is first placed in the river, and people rotate the adjusting mechanism 8 to make the limit ring 2 drive the water suction pipe 1 to move downward, and the water suction mechanism 7 moves downward at the same time. After moving to the position where it needs to be used, the adjusting mechanism 8 is no longer rotated, and the limit ring 2 stops moving. At this time, people start the water suction mechanism 7, and the water suction mechanism 7 moves downward along the water suction pipe 1 without reacting. Then the water suction mechanism 7 moves upward along the water suction pipe 1, and can absorb the river water into the water suction pipe 1. Then people rotate the ball valve 5 to make the opening of the ball valve 5 correspond to the opening of the water inlet pipe 4. The water inlet pipe 4 is a hose that can be pulled, and the water absorption mechanism 7 moves downward to squeeze the water absorption pipe 1, and the water in the water absorption pipe 1 flows along the water inlet pipe 4, and at the same time flows along the water inlet pipe 4 to the collecting bucket 6, so that the river water can be collected. After the collection work is completed, the ball valve 5 is rotated in the opposite direction so that the opening of the ball valve 5 does not correspond to the opening of the water inlet pipe 4, and people rotate the adjusting mechanism 8 in the opposite direction to move the limit ring 2 upward, and the limit ring 2 drives the water absorption pipe 1 to move upward, and the water absorption mechanism 7 moves upward at the same time, and finally the river water can be collected, sealed and preserved for the purpose of subsequent detection of the river water. After the operation is completed, the water absorption mechanism 7 can be closed.

[0031] The water absorption mechanism 7 includes a first limit block 70, a cylinder 71 and a piston 72. Two first limit blocks 70 are slidably provided on the left and right sides of the limit column 3. A cylinder 71 is installed between the two first limit blocks 70.

[0032] When it is necessary to absorb and collect river water, people pull the limit ring 2 and the first limit block 70 downward at the same time, the limit ring 2 drives the suction pipe 1 downward, the suction pipe 1 moves downward and contacts the river water, the first limit block 70 drives the cylinder 71 downward, the cylinder 71 drives the piston 72 downward, at this time, the cylinder 71 is started, the cylinder 71 drives the piston 72 to move downward along the suction pipe 1, and will not react. When the cylinder 71 drives the piston 72 upward, the river water can be absorbed into the suction pipe 1, and then people turn the ball valve 5, the ball valve 5 opening is rotated to correspond to the water inlet pipe 4 opening, the piston 72 moves downward to squeeze the river water in the suction pipe 1, and the river water flows along the water inlet pipe 4, and then flows into the collection bucket 6. After the collection work is completed, people turn the ball valve 5 in the opposite direction so that the ball valve 5 does not correspond to the water inlet pipe 4 opening, and finally the purpose of absorbing and collecting the river water can be achieved.

[0033] The adjusting mechanism 8 includes a first screw 80, a first rotating ring 81, a pulley 82 and a flat belt 83.

The two first screws 80 are connected with pulleys 82, and a flat belt 83 is wound between the two pulleys 82.

[0034] When it is necessary to adjust the height of the limit ring 2 and the first limit block 70, people rotate the left first rotating ring 81 to drive the left first screw 80 to rotate, and the left first screw 80 drives the pulley 82 to rotate. Under the cooperation of the pulley 82 and the flat belt 83, the pulley 82 drives the right first screw 80 to rotate, and the two first screws 80 rotate at the same time, so that the limit ring 2 and the first limit block 70 move downward, the limit ring 2 drives the water suction pipe 1 to move downward, and the first limit block 70 drives the cylinder 71 to move downward. After adjusting to the required height, the first rotating ring 81 is stopped, so that the limit ring 2 and the first limit block 70 stop moving. When it is necessary to move the limit ring 2 and the first limit block 70 upward, people rotate the first rotating ring 81 in the opposite direction to drive the first screw 80 to rotate in the opposite direction, the limit ring 2 and the first limit block 70 move upward, and the water suction pipe 1 and the cylinder 71 move upward at the same time, and finally the purpose of adjusting the height of the limit ring 2 and the first limit block 70 can be achieved.

The first return spring 93 is compressed, and then the pressure rod 91 is aligned with the position to be fixed, and no force is applied to the pressure rod 91. Under the reset action of the first return spring 93, the pressure rod 91 drives the drill bit 92 to move downward, so that it moves to contact the soil.

Under the resetting action of the second return spring 104, the clamping block 103 moves inward so as not to contact the soil, and then people pull up the pressure rod 91, and the pressure rod 91 drives the drill bit 92 to move upward, and finally the drill bit 92 can be prevented from being unstable, thereby strengthening the fixation purpose.

[0040] It also includes a transmission mechanism 11, which includes a motor 110, a missing gear 111, a turntable 112, a support frame 113, a rotating shaft 114, a spur gear 115 and a discharge tray 116.
