[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0026] As Figures 1-11 shown, the utility model provides following several technical schemes, a kind of portable geological drilling water sample collection device, including inner support 1 and rubber film 2, the rubber film 2 cover in the outer portion of inner support 1, and rubber film 2 bottom end is closed, upper end is open, the inner support 1 is equipped with handle 3 extending outward on it, the inner support 1 includes multiple fixed cross bar 101 and center shaft 102 (fixed cross bar 101 is fixedly connected with center disc, center shaft 102 is connected with center disc), expansion rod 4 is slidably sleeved on each fixed cross bar 101, the outer end of expansion rod 4 is connected with rubber film 2, expansion rod 4 is connected with control main rod 6 by hinged support rod 5. As Figure 6 shown, the both ends of support rod 5 are respectively hinged with expansion rod 4 and the side wall of control main rod 6, when moving control main rod 6 downward, expansion rod 4 can be pushed outward by support rod 5, drive rubber film 2 to prop up outward, to play the role of guaranteeing certain form (although it cannot guarantee that form is completely fixed, but at least can have the frame form of multiple expansion rods 4), i.e. when control main rod 6 is pulled up and down, rubber film 2 can be contracted or expanded by expansion rod 4.

[0027] Of course, the number of expansion rod 4 (corresponding fixed cross bar 101) is not limited, the more the number is, the more stable the form is, but cost and weight will increase relatively, according to actual demand to select manufacture.

[0028] Preferably, in order to improve the convenience of use, the control main rod 6 can be positioned after moving, the control main rod 6 is sleeved on the central shaft 102, and the control main rod 6 is provided with a positioner. The positioner comprises a knob 601 engaged with the control main rod 6, and the control main rod 6 is provided with a thread, and the knob 601 is engaged with the thread provided on the control main rod 6. The upper end of the control main rod 6 is connected (can be connected by gluing) with a rubber sleeve 602, and the rubber sleeve 602 extends to the outside of the control main rod 6, and the part extending to the outside is split (as shown in Figure 8 ), the inner diameter of the knob 601 gradually changes (as shown in Figure 9 ), when the knob 601 is continuously screwed into the control main rod 6, the rear end of the knob 601 gradually extrudes the rubber sleeve 602 to extrude the central shaft 102, so that the control main rod 6 and the central shaft 102 are fixed in position, and this way can be fixed in a stepless way, so that the size can be adjusted according to the actual size of the sampling hole, and sampling is facilitated.

[0029] Similar to the case of increasing the number of expansion rods 4 (corresponding to the fixed cross rod 101) as described above, the fixed cross rod 101 is distributed in groups at different heights (the expansion rod 4 and the support rod 5 are also multiple and grouped according to height), as shown in Figure 7 . Specifically, the fixed cross rod 101 can be provided in two groups, and the lower side of the expansion rod 4 sleeved on the lower fixed cross rod 101 is connected with the bottom end of the rubber film 2 (the connection mode is multi-point bonding, that is, the bottom of the expansion rod 4 is bonded with the upper side of the bottom end of the rubber film), and this part of the expansion rod 4 and the cross rod 101 not only serves as support for outward expansion, but also serves as bottom support when containing sampling water. As shown in Figure 10 , specifically, the expansion rod 4 can be connected to the rubber film 2 in the form of a plug (the plug is inserted into the expansion rod 4 by interference fit, and the other end can be connected to the rubber film 2 by gluing), so that when wear occurs and needs to be replaced, only the external structure and the rubber film 2 need to be replaced, and the internal structure does not need to be replaced; of course, it should be noted that the length of the plug cannot affect the sliding of the expansion rod 4 on the cross rod 101,

[0030] In addition, it should be noted that when multiple layers are provided, the position where the control main rod 6 passes through one layer is partially hollow (as shown in Figure 7 ), so that the support rod 5 of different height layers can be connected and pushed to drive the corresponding expansion rod 4.

[0031] Further, the outer side of the rubber film 2 is connected with the stainless steel sheet 8 through the connecting rubber pad 7 (the edge of the stainless steel sheet 8 is rounded to prevent cutting), and the connecting mode between the connecting rubber pad 7 and the stainless steel sheet 8 and the rubber film 2 can also be adhesive, the cross section of the stainless steel sheet 8 is arc-shaped, and a plurality of connecting rubber pads 7 (which can be adhesive) are connected in a multi-point form on the same stainless steel sheet 8, and the stainless steel sheet 8 can be wrapped outside during contraction, so that the wear resistance during transportation can be improved, and the service life is prolonged, and attention is paid to that the rubber film 2 is soft and deformable during contraction and is folded to the inner side of the stainless steel sheet 8 to prevent damage caused by pinching.

[0032] Further, in order to increase the sampling amount after expansion without increasing the contraction volume, the expansion rod 4 is a telescopic rod composed of a plurality of sleeve rods 401, and the cross-sectional view of the plurality of sleeve rods 401 is as shown in Figure 11 The plurality of sleeve rods 401 are connected in a sliding clamping mode (the purpose of clamping is to prevent disconnection and facilitate linkage), and the same mode is adopted between the end of the expansion rod 4 and the fixed horizontal rod 101 to prevent disconnection, and the connecting point of the supporting rod 5 and the expansion rod 4 is located on the outermost sleeve rod 401.

[0033] Working principle: when it is needed to be used, the device is taken off from the transport vehicle, the hand handle 3 (provided on the central shaft 102) is held and the control main rod 6 is pulled, then the outer diameter of the expanded rubber film 2 is determined according to the size of the drilled hole, then the position of the control main rod 6 and the central shaft 102 is fixed by using the positioner, then the expanded device is inserted into the sampling hole, then sampling is performed, after sampling is completed, the device is taken out of the hole, the water sample is transferred to a container, then the positioner can be loosened, and the control main rod 6 is pulled, so that the expansion rod 4 is pulled inward, so that the rubber film 2 (driving the stainless steel sheet 8) is contracted, thereby reducing the volume and improving the portability. It should be noted that the central shaft 102 can be provided with threads at the end (not shown in the figure), so that a plurality of extension rods can be connected to adapt to different site situations.

[0034] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
