Further, the fixed cover is fixedly connected with the fixed block, and the barrel is connected with the fixed cover in a threaded mode.

Furthermore, the filter screen is sleeved on the outer surface of the barrel, and a waterproof rubber ring is arranged between the filter screen and the barrel.

Further, an annular groove is formed in the bottom end of the stretching pipe, the top end of the fixed cylinder extends into the annular groove, an annular clamping groove is formed in the inner wall of the annular groove, an annular clamping block is arranged at one end, located inside the annular groove, of the fixed cylinder, and the annular clamping groove and the annular clamping block are clamped or separated.

Furthermore, the sections of the annular clamping groove and the annular clamping block are both arc-shaped.

Furthermore, the annular air bag is externally connected with an air pump through an air pipe, and the proximity switch is electrically connected with the air pump connected with the annular air bag.

Furthermore, a first water inlet is formed in the surface of the fixing plate, and a second water inlet is formed in the side wall of the fixing cover.

The utility model has the advantages that:

when the utility model is used, when the device is extended to the required depth, the water layer can not be disturbed, which is helpful for the collection accuracy; through the setting of annular gasbag, proximity switch, floater, suspension pole isotructure, can rotate the shutoff with the department of intaking, can avoid when taking out the sample, the sample can not be polluted by upper water, has certain practicality.

Detailed Description

Fig. 1 to 3 show, relate to a hydrogeology groundwater sample thief, including stretching into pipe 1, stretch into 1 inside fixed block 2 that is provided with of pipe, the bottom of fixed block 2 is provided with the sampler barrel, the sampler barrel includes barrel 9 and fixed cover 8, the inside fixedly connected with fixed plate 14 of barrel 9, the below of fixed plate 14 is provided with floater 10, the top of floater 10 is fixed with suspension rod 11, the top fixedly connected with that suspension rod 11's top extends to fixed plate 14 is close piece 12, the interior roof of fixed cover 8 is provided with proximity switch 7, the bottom inner wall that stretches into pipe 1 is provided with annular gasbag 3, and the below that stretches into pipe 1 is provided with solid fixed cylinder 4, the bottom fixedly connected with filter screen 5 of solid fixed cylinder 4.

During the use, inflate annular gasbag 3 earlier through external air pump, make annular gasbag 3 inflate the outer wall of cladding barrel 9 and fixed lid 8, then stretch into pipe 1 with barrel 9 utilization and stretch into required position, to the gassing of annular gasbag 3 after reacing, water gets into barrel 9 through filter screen piece 5 and will float floater 10, floater 10 floats and rises to make suspension rod 11 drive and is close piece 12 and rise, after barrel 9 is inside to fill up water, it rises to proximity switch 7 department to be close piece 12, open external air pump, inflate annular gasbag 3 once more, it is sealed to make its mouth of pipe that will stretch into pipe 1, avoid water to get into from second water inlet 15.
