Description

Technical Field

[0001] The utility model relates to the technical field of sampling equipment, in particular to groundwater sampling equipment for ecological environment monitoring. Background Art

[0002] In ecological and environmental monitoring, it is necessary to sample and test groundwater, analyze and evaluate the water quality of the area, help discover possible environmental risks, and take timely control and restoration measures. Sampling equipment will be used in the sampling process. Deep groundwater will be sampled in well pipes laid in advance from the surface to the bottom. Traditional methods mostly use suction pumps with suction hoses for suction, but when used outdoors, it is necessary to consider the power supply and the difficulty of carrying equipment.

[0003] A Chinese patent discloses groundwater sampling equipment for ecological protection monitoring (authorization announcement number CN117147220B). The patented technology includes a storage box with a follower mechanism inside, and a storage mechanism located in the storage box is provided on one side of the follower mechanism; a winder is connected to one end of the follower mechanism and a restraining tube is wound around it; an actuator is connected to the bottom of the restraining tube and is used for mobile collection. The present invention can determine the position of the actuator and then determine the sampling at different levels. Similarly, through the storage in the accommodating cavity, the temperature of the water body can be maintained when sampling, reducing the error of subsequent detection and further ensuring the accuracy of the data.

[0004] This patented technology has multi-level sampling when in use, but there are still some shortcomings in its use. The overall structure of the equipment is large and requires the use of electrical equipment. It cannot be effectively used in places where electricity is not available. It has a complex structure, high cost of use, and is not flexible enough. Therefore, those skilled in the art provide a groundwater sampling device for ecological environment monitoring to solve the problems raised in the above background technology. Utility Model Content

[0008] The sampling structure includes a sampling tube, a water inlet bucket installed inside the upper end of the sampling tube and distributed in a circular array, and a water collection bucket located inside the upper end of the sampling tube and connected to the sampling tube at the upper end side;

[0009] as well as;

[0010] The winding structure includes a rotating shaft rotatably installed inside the mounting frame, a rotating handle located at one end of the rotating shaft, a handle fixed to the upper end of the mounting frame, and a connecting rope wound around the outer wall of the rotating shaft.

[0011] Furthermore, the upper end of the sampling tube is connected to the connecting rope, the outer side of the upper end of the sampling tube is sleeved with a filter cover located outside the water inlet bucket, and the lower end of the filter cover is provided with a support ring sleeved on the outer wall of the sampling tube;

[0012] Specifically, the filter cover filters the groundwater passing through to prevent the entry of foreign matter and sand and gravel, and is fixed to the outside of the water inlet bucket through a support ring.

[0013] Furthermore, a counterweight ring is sleeved on the outer wall of the lower end of the sampling tube;

[0014] Specifically, the weight ring on the outer wall of the lower end of the sampling tube increases its weight so that it can be effectively submerged in water, and the sampling tube at the weight ring faces downward to facilitate water inlet.

[0015] Furthermore, a water outlet is provided at the lower end of the sampling tube, and a screw cap is rotatably sleeved at the lower end of the water outlet;

[0016] Specifically, the groundwater sampled by the sampling tube is discharged through the water outlet, and the opening and closing of the water outlet is controlled by screwing the cap.

[0017] Furthermore, the outer wall of the rotating shaft is provided with symmetrically distributed limiting rings located outside the connecting rope;

[0018] Specifically, the limiting ring limits the reeled connecting rope.

[0019] Furthermore, a fixing structure is provided inside the upper end of the mounting frame, and the fixing structure includes a screw hole opened inside the upper end of the mounting frame, a screw rod rotatably inserted into the screw hole, a twist handle fixed on the upper end of the screw rod, a pressure cover located at the lower end of the screw rod, and a bearing embedded in the upper end of the pressure cover and rotatably mounted with the lower end of the screw rod;

[0020] Specifically, the gland is pushed by the screw to press the upper end of the wound connecting rope, so that the connecting rope remains stable when not in use.

[0021] 2. Beneficial effects

[0022] Compared with the prior art, the advantages of the present invention are:

[0023] The utility model is connected to the sampling structure by a manually retracted connecting rope, and the sampling structure is retracted and extended. During the retraction and extension process, the handheld device is convenient for adjusting the depth. After use, it can be directly grasped and taken. The device is compact and simple in structure, and is convenient for sampling groundwater during ecological environment monitoring.

[0024] At the same time, a plurality of funnel-shaped water inlet buckets are provided on the upper end of the sampling structure. The small end of the water inlet bucket passes through the sampling tube, and the water inlet at the small end collects the groundwater into the water collecting bucket. The small end of the water collecting bucket faces downward. Without installing a closed structure at the sampling water inlet, the lifting process of the sampling tube reduces water leakage, ensuring the retention of a large amount of sampled water. No electrical equipment is required to achieve groundwater sampling. The sampling equipment is easy to use and has low cost.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] Next, the present invention is described in detail with reference to schematic diagrams.

[0038] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0039] Example 1

[0040] See also Figures 1-4 As shown, this embodiment is a groundwater sampling device for ecological environment monitoring, including a mounting frame 101,

[0041] The sampling structure 200 includes a sampling tube 203, a water inlet hopper 207 installed in the upper end of the sampling tube 203 and arranged in a circular array, and a water collection hopper 208 located in the upper end of the sampling tube 203 and connected to the sampling tube 203 at the upper side.

[0042] as well as;

[0043] The winding structure 100 includes a shaft 102 rotatably mounted inside the mounting frame 101 , a handle 103 at one end of the shaft 102 , a handle 105 fixed to the upper end of the mounting frame 101 , and a connecting rope 106 wound around the outer wall of the shaft 102 .

[0044] The upper end of the sampling tube 203 is connected to the connecting rope 106 , and the outer side of the upper end of the sampling tube 203 is sleeved with a filter cover 201 located outside the water inlet bucket 207 , and the lower end of the filter cover 201 is provided with a support ring 202 sleeved on the outer wall of the sampling tube 203 .

[0045] The outer wall of the lower end of the sampling tube 203 is sleeved with a weight ring 204;

[0046] The lower end of the sampling tube 203 is provided with a water outlet 205, and the lower end of the water outlet 205 is rotatably sleeved with a screw cap 206;

[0047] The outer wall of the rotating shaft 102 is provided with symmetrically distributed limiting rings 104 located outside the connecting rope 106;

[0048] Use of the sampling structure 200 and the winding structure 100;

[0049] Grab the handle 105 with one hand, and grasp the rotating handle 103 with the other hand and rotate it to release the wound connecting rope 106. The sampling tube 203 descends and enters the well pipe. When entering the groundwater, the counterweight ring 204 enters the water. The sampling tube 203 at the counterweight ring 204 faces downward, which is convenient for the water inlet bucket 207 to enter. The groundwater is transported to the water collection bucket 208 through multiple water inlet buckets 207, and enters the interior of the sampling tube 203 through the water collection bucket. After sampling, rotate the rotating handle 103 in the opposite direction to reel in the connecting rope 106.

[0050] Due to the action of the counterweight ring 204 in the sampling structure 200, the opening of the water inlet bucket 207 faces upward. During the shaking process, the sampling tube 203 needs to pass through the lower opening of the small-diameter water collecting bucket 208 and then enter the lower opening of the small-diameter water inlet bucket 207 before it leaks to the outside. The small-diameter openings of the water inlet bucket 207 and the water collecting bucket 208 are misaligned, making it difficult for the water inside the sampling tube 203 to spill out. In the case that no closed structure is set at the water intake opening, effective sampling of groundwater is carried out, avoiding the use of a closed structure. In the process of monitoring the ecological environment, the sampling structure 200 is small and simple in structure, avoiding the use of electrical equipment, with low cost and easy use. Effective groundwater sampling can still be carried out at sampling locations without power supply.

[0051] Example 2

[0052] See also Figures 1-4 As shown, this embodiment is based on embodiment 1 and also includes:

[0053] A fixing structure 300 is provided inside the upper end of the mounting frame 101. The fixing structure 300 includes a screw hole 305 provided inside the upper end of the mounting frame 101, a screw rod 304 rotatably inserted into the screw hole 305, a twist handle 303 fixed to the upper end of the screw rod 304, a pressure cap 301 located at the lower end of the screw rod 304, and a bearing 302 embedded in the upper end of the pressure cap 301 and rotatably mounted to the lower end of the screw rod 304.

[0054] Performing the use of the fixed structure 300;

[0055] After the sampling is completed, grasp the twist handle 303 to drive the screw 304 to rotate inside the screw hole 305. The rotational force of the screw 304 acts on the inside of the bearing 302, making the pressure cover 301 relatively stable. When the pressure cover 301 contacts the connecting rope 106, the rotational friction of the connecting rope 106 is reduced, and the connecting rope 106 is protected. When the pressure cover 301 presses the upper end of the connecting rope 106, the wound connecting rope 106 remains stable to avoid loosening.
