Due to the cooperation between the weight block and the clamping ring, it is ensured that the sampling bottle will not be separated from the mounting plate. When the sampling bottle reaches a certain depth, the handle is turned to drive the reel to rotate on the bottom plate. The rotation of the reel causes the pull rope to wrap around the reel and pull the blocking cover to move upward and create a certain gap with the bottle mouth of the sampling bottle.

DETAILED DESCRIPTION

[0017] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0018] The first embodiment of the present application is:

[0019] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of a groundwater resource survey sampling device according to the first embodiment of the utility model. Figure 2 It is a schematic diagram of the connection between the sampling bottle and the sealing cover of the first embodiment of the utility model.

[0020] The utility model provides a groundwater resource investigation sampling device: including a base plate 101, a support plate 102, a mounting plate 103, a sampling bottle 104 and a lifting device, and also including a blocking device, the blocking device including a blocking cover 108, a connecting spring 109 and a pulling assembly, the pulling assembly including a pull rope 111, a reel 112 and a handle 113, the blocking device also includes a filter cartridge 114, and the above-mentioned scheme solves the problem that the above-mentioned device cannot block the sampling barrel during sampling, so that groundwater at different levels is mixed in the sampling barrel, thereby causing inaccurate sampling investigation results. It can be understood that this scheme can also be used to solve the problem of driving the sampling bottle to rise and fall.

[0021] In this embodiment, through the cooperation between the blocking cover 108, the lifting assembly and the connecting spring 109, sampling can be performed only when the sampling bottle 104 reaches a specified depth, thereby ensuring the accuracy of the groundwater survey results.

[0022] Among them, the connecting spring 109 is fixedly installed in the sampling bottle 104, the blocking cover 108 is fixedly connected to one end of the connecting spring 109, and the blocking cover 108 is provided with an annular groove 110, and the blocking cover 108 is engaged with the sampling bottle 104 through the annular groove 110, and the lifting assembly is installed on the bottom plate 101, the sampling bottle 104 is cylindrical, hollow inside, and open at the upper end, the roller 105 is a universal wheel, the weight block 107 is a solid steel column, the diameter of the weight block 107 is smaller than the diameter of the sampling bottle 104, the bottle mouth of the sampling bottle 104 is embedded in the annular groove 110 on the blocking cover 108, and the axis of the connecting spring 109 coincides with the axis of the sampling bottle 104 When the sampling bottle 104 enters the groundwater, the blocking cover 108 is pulled up by the lifting assembly, so that a gap is generated between the blocking cover 108 and the bottle mouth of the sampling bottle 104, and the connecting spring 109 is stretched by the pulling force of the blocking cover 108, and the groundwater enters the sampling bottle 104 through this gap. When the sampling is completed, the lifting assembly no longer pulls the blocking cover 108, and the connecting spring 109 drives the blocking cover 108 to re-seal the sampling bottle 104 through its own elastic force. Therefore, through the mutual cooperation of the blocking cover 108, the lifting assembly and the connecting spring 109, sampling can be carried out only when the sampling bottle 104 reaches the specified depth, thereby ensuring the accuracy of the groundwater survey results.

[0023] Secondly, the drum 112 is rotatably installed on the base plate 101; one end of the pull rope 111 is wound around the drum 112, and the other end of the pull rope 111 is fixedly connected to the blocking cover 108; the handle 113 is fixedly installed on the drum 112, and the drum 112 is rotatably installed on the base plate 101 through a rotating shaft. The pull rope 111 is a sampling steel rope, and the handle 113 is Z-shaped. By rotating the handle 113, the drum 112 is driven to rotate on the base plate 101, so that the steel rope is wound and contracted, and the blocking cover 108 is pulled upward, thereby achieving a pulling effect on the blocking cover 108.

[0024] Again, the filter cartridge 114 is fixedly mounted on the blocking cover 108 and is located on one side of the blocking cover 108 close to the annular groove 110. The filter cartridge 114 is through-shaped at the top and bottom, and a plurality of through holes are provided on its side wall. The outer wall of the filter cartridge 114 contacts the inner wall of the sampling bottle 104. When groundwater enters the sampling bottle 104, the filter cartridge 114 can filter out impurities in the groundwater through the setting of the filter cartridge 114.

[0025] In this embodiment, when in use, the sampling bottle 104 on the mounting plate 103 is driven into the groundwater by the lifting device. Due to the cooperation between the weight block 107 and the clamping ring 106, it is ensured that the sampling bottle 104 will not be separated from the mounting plate 103. When the sampling bottle 104 reaches a certain depth, the handle 113 is rotated to drive the reel 112 to rotate on the bottom plate 101. The rotation of the reel 112 causes the pull rope 111 to wrap around the reel 112, and pulls the blocking cover 108 to move upward, and a certain gap is generated with the bottle mouth of the sampling bottle 104. At this time, the link spring is subjected to tension and is in a stretched state. At the same time, the groundwater enters through the gap between the blocking cover 108 and the bottle mouth of the sampling bottle 104. In the sampling bottle 104, when sampling is completed, the reel 112 is rotated in the opposite direction by the handle 113 to release the pull rope 111. At this time, the pull rope 111 no longer generates tension on the blocking cover 108. The blocking cover 108 is reset under the elastic force of the connecting spring 109 and re-engaged with the sampling bottle 104. Then, the sampling bottle 104 is driven up again by the lifting device until it moves out of the groundwater surface. At the same time, the sampling bottle 104 is slid off the mounting plate 103 to take out the sampled groundwater. Therefore, the blocking cover 108, the lifting assembly and the connecting spring 109 cooperate with each other, so that sampling can be carried out only when the sampling bottle 104 reaches the specified depth, thereby ensuring the accuracy of the groundwater survey results.

[0026] The second embodiment of the present application is:

[0027] See also Figure 3 ,in Figure 3 It is a schematic diagram of the overall structure of a groundwater resource investigation and sampling device according to the second embodiment of the utility model.

[0028] In this embodiment, the threaded rod 201 is lifted and lowered through the sampling bottle on the mounting plate 103 by the driving effect of the cylinder 203 and the motor 202, thereby achieving a lifting effect on the sampling bottle.

[0029] Among them, the cylinder 203 is fixedly mounted on the support plate 102; the lifting plate 204 is mounted on the output end of the cylinder 203; the motor 202 is fixedly mounted on the lifting plate 204; the threaded rod 201 is fixedly mounted on the output shaft of the motor 202 and is threadedly connected to the mounting plate 103; the limiting rod 205 is fixedly mounted on the lifting plate 204 and passes through the mounting plate 103, the cylinder 203 is fixed to the top of the support plate 102 by the screws, the lifting plate 204 is welded to the output end of the cylinder 203, and the motor 2 02 is fixed to the bottom of the lifting plate 204 by screws, and the threaded rod 201 is parallel to the axis of the limiting rod 205. When in use, the cylinder 203 is started to drive the lifting plate 204 to move downward, and the motor 202 is started to rotate the threaded rod 201, so that the threaded rod 201 drives the mounting plate 103 to move downward along the limiting rod 205 through the threaded connection, and further drives the sampling bottle into the groundwater. When the sampling is completed, the sampling bottle is driven out of the groundwater surface through the above steps again, thereby achieving the lifting effect of the sampling bottle.

[0030] Secondly, the limiting block 206 is fixedly mounted on the limiting rod 205 , and the limiting block 206 is welded to the bottom of the limiting rod 205 . The setting of the limiting block 206 prevents the mounting plate 103 from being separated from the limiting rod 205 .

[0031] In this embodiment, when in use, the cylinder 203 is started to drive the lifting plate 204 to move downward, and the motor 202 is started to drive the threaded rod 201 to rotate, so that the threaded rod 201 drives the mounting plate 103 to move downward along the limiting rod 205 through the threaded connection, and further drives the sampling bottle into the groundwater. When the sampling is completed, the sampling bottle is driven out of the groundwater surface through the above steps again, thereby achieving the lifting effect of the sampling bottle.
