A float sampling head 7 is fixedly connected to the end of the water pipe 6 away from the pump 5. Several water sample storage tanks are set inside the housing 1.
[0035] Among them, the semi-circular plate 22 and the brush 23 can clean the outer wall of the pointed support rod 10 of the extension device, so as to avoid the mud and sand remaining on the surface of the pointed support rod 10 and affecting its service life.
[0036] The working principle of the above embodiment is as follows: when sampling, the worker moves the whole device through the telescopic pull rod 4 and the universal wheel 8, and stops on a flat ground in the wild. When stopping on a flat ground in the wild, the movement of the universal wheel 8 can be limited by stepping on the brake, then the float sampling head 7 can be put into the water, and then the pump 5 is started to pump the water sample from the water pipe 6 into the sample tank in the box body 1, and then the controller 2 is used for detection and analysis, and the worker observes and operates the display screen 3 to process data. When stopping on a rough ground in the wild, according to the terrain, the first hand wheel 9 or the second hand wheel 11 can be rotated alone, and then the worm 15 is rotated through the first shaft 17 or the second shaft 18, and then the worm 15 drives the worm wheel 16 to rotate synchronously, and the rotating sleeve 13 is driven to rotate synchronously by the worm wheel 16, and then the sharp support rod 10 is moved towards the ground by the extrusion of the reciprocating thread groove 14 of the rotating sleeve 13, until the box body 1 is supported, and the external portable level meter is used for accurate adjustment. Through the sharp support rod 10 with adjustable height, the device can effectively adapt to different terrains in the wild. When the box body 1 needs to stop on a slope, the pair of sharp support rods 10 usually need to be adjusted synchronously. At this time, the worker can manually push the rectangular bar 12 into the first shaft 17 for clamping, synchronously push the limiting rod 19 to compress the reset spring 26, and then slide the clamping block 24 to the middle of the pair of guide plates 25, so that the end of the rectangular bar 12 abuts against the limiting position. The limiting rod 19 compresses the reset spring 26, and at the same time, the protrusion 27 is also driven to slide away from the side of the clamping groove 20 away from the reset spring 26, so that the protrusion 27 is clamped and limited, which is equivalent to locking the first shaft 17 and the second shaft 18 as a whole. At this time, whether the first hand wheel 9 or the second hand wheel 11 is rotated, the two can be rotated synchronously. Then, according to the above principle, the pair of sharp support rods 10 are finally moved up and down synchronously, the side height of the box body 1 is adjusted, and finally the device is leveled, which is beneficial to obtain water samples from different positions of the water area and increases the environmental adaptability of the device. In addition, through the design of the one-way thread groove 21 at the bottom of the sharp support rod 10, the sharp support rod 10 can be screwed into the soil, thereby enhancing the stability of the device. At the same time, when the sharp support rod 10 is retracted into the device, it first passes through the area of the semicircular plate 22, and the brush 23 on the inner wall of the semicircular plate 22 can clean the outer wall of the sharp support rod 10 extending out of the device, so as to avoid the influence of mud and sand remaining on the surface of the sharp support rod 10 on its service life. The separate and combined adjustment of the sharp support rod 10 and the reusability of the sharp support rod 10 can effectively shorten the sampling time of the device, reduce the workload of the operator, and thereby improve the sampling efficiency.
