Description

Technical Field

[0001] This utility model belongs to the field of geological exploration technology, specifically relating to a portable hydrogeological exploration sampling device. Background Technology

[0002] Hydrogeological exploration is mainly aimed at clarifying the hydrogeological conditions of mineral deposits, including the formation, distribution, and movement patterns of groundwater. This provides a basis for the rational exploitation and utilization of water resources and for the design and construction of foundation and piling projects. It usually requires drilling with exploration sampling equipment to obtain groundwater samples and rock cores to analyze the chemical composition and geological structure of groundwater. Hydrogeological exploration is of great significance for the rational utilization and protection of groundwater resources.

[0003] However, current hydrogeological exploration sampling devices are often bulky and complex to operate, making them inconvenient to use in complex field environments. Although small exploration sampling devices exist on the market, their structures are simple and lack protection for the sampling tube. During transport, the sampling tube is often exposed, making it easy for the sharp part at the bottom of the sampling tube to come into contact with objects or people, causing injury. This brings a lot of inconvenience to the use of hydrogeological exploration sampling. Therefore, the applicant proposes a portable hydrogeological exploration sampling device to solve the above problems. Utility Model Content

[0029] Example 1:

[0030] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a portable hydrogeological exploration sampling device includes:

[0031] The support mechanism 3 and the movable mechanism 2 mounted on the support mechanism 3, and the sampling mechanism 1 mounted inside the support mechanism 3;

[0032] The support mechanism 3 includes a fixed frame 31, and a plurality of support rods 32 arranged in a ring array are hinged to the bottom of the fixed frame 31. Each support rod 32 is movably connected to a protective cover 33 at its bottom end.

[0033] The movable mechanism 2 includes a movable frame 21 that is slidably mounted on the top of the fixed frame 31. The bottom of the movable frame 21 is fixed with a plurality of fixed rods 22 arranged in a circular array and passing through the fixed frame 31. The bottom of each fixed rod 22 is hinged to the outside of the protective cover 33.

[0034] The sampling mechanism 1 includes a rotating rod 11 that is installed through the fixed frame 31, and a drill barrel 15 extending into the protective cover 33 is fixed at the bottom of the rotating rod 11.

[0035] As can be seen from the above, during use, by pressing the movable frame 21 downwards, the movable frame 21 is made to fit against the top of the fixed frame 31. At the same time, the fixed rod 22 can be moved downwards. Utilizing the downward movement of the fixed rod 22 and the pulling force of the support rod 32 on the protective cover 33, the protective cover 33 can be flipped and unfolded into a horizontal state. By fitting the unfolded protective cover 33 against the ground, the protective cover 33 can act as a support base, providing support during drilling operations. By driving the rotating rod 11 to rotate, the drill barrel 15 can be rotated synchronously, making it easy to drill the drill barrel 15 into the ground, allowing soil to enter the drill barrel 15 for convenient sampling operations. It can be used in complex field environments, bringing more convenience to hydrogeological exploration and sampling.

[0036] After use, the drill barrel 15 can be reset by pulling the movable frame 21 upwards. The protective cover 33 can be folded and reset by using the fixed rod 22. The protective cover 33 can wrap around the drill barrel 15, which can effectively prevent the sharp parts at the bottom of the drill barrel 15 from coming into contact with external objects or personnel during carrying. It can be carried easily and the safety effect during carrying is improved.

[0037] Depend on Figure 4 It can be seen that a movable sleeve 13 is rotatably installed on the outer side of the rotating rod 11, and a pressing handle 14 is fixed on one side of the movable sleeve 13.

[0038] As can be seen from the above, by using the bearing to rotate the movable sleeve 13 and the rotating rod 11, the rotating rod 11 can rotate within the movable sleeve 13. By holding and pressing the handle 14, the movable sleeve 13 can be pressed down, which can synchronously drive the rotating rod 11 to move down. This allows pressure to be applied to the drill barrel 15, enabling the drill barrel 15 to move down into the ground during rotation, facilitating sampling operations.

[0039] For details, please refer to Figure 4 As shown, a turntable 12 is fixed to the top of the rotating rod 11, and breaking teeth 16 are evenly distributed at the bottom of the drill barrel 15.

[0040] As can be seen from the above, by using the turntable 12, the rotating rod 11 can be easily rotated, which can synchronously drive the drill barrel 15 to rotate. The breaking teeth 16 can break the soil on the ground, so that the drill barrel 15 can drill into the ground more easily.

[0041] For details, please refer to Figure 1 , Figure 2 and Figure 3 As shown, handles 23 are installed around the movable frame 21, and the surface of the handles 23 is covered with anti-slip sleeves.

[0042] As can be seen from the above, by holding the handle 23, the movable frame 21 can be moved up and down easily, the protective cover 33 can be opened and closed easily, and the device can be easily lifted and carried by using the handle 23.

[0043] Example 2:

[0044] refer to Figure 4 and Figure 5 As shown, the center of the fixed frame 31 has an opening 38 for the rotating rod 11 to move up and down, and the outer side of the fixed frame 31 is threaded with a fixing bolt 37 corresponding to the fixed rod 22.

[0045] As can be seen from the above, the rotating rod 11 can be rotated through the movable port 38 without affecting the up and down movement of the rotating rod 11. The fixed rod 22 can be squeezed by rotating the fixing bolt 37, which can easily fix the fixed rod 22 and prevent the protective cover 33 from becoming loose due to the up and down movement of the fixed rod 22.

[0046] refer to Figure 3 As shown, the support rod 32 and the surface of the protective cover 33, as well as the bottom of the fixing frame 31, are movably installed through the movable seat 35, and the fixing rod 22 and the surface of the protective cover 33 are hinged through the hinge seat 36.

[0047] As can be seen from the above, when the protective cover 33 is flipped by the movable seat 35, the support rod 32 can move accordingly. The hinge seat 36 allows the fixed rod 22 to move with the protective cover 33, which can facilitate the opening and closing of the protective cover 33.

[0048] refer to Figure 2 and Figure 3 As shown, anti-slip teeth 34 are evenly distributed on the inner side of the protective cover 33, and the anti-slip teeth 34 are interlocked.

[0049] As can be seen from the above, when the protective cover 33 is unfolded and attached to the ground, the anti-slip teeth 34 can increase the friction between the protective cover 33 and the ground, and prevent slippage during the support process. At the same time, when the protective cover 33 is closed, the anti-slip teeth 34 can mesh with each other, which can not affect the closing effect of the protective cover 33, and facilitate the wrapping and protection of the drill barrel 15.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
