Description

Technical Field

[0001] This application relates to the field of dredging technology, and more specifically, to a highly efficient and portable dredging device for groundwater sampling. Background Technology

[0002] Groundwater is mainly found in loose sediments and less consolidated rock strata. It is generally abundant and has significant exploitation value. It is distributed in major plains, intermontane basins, large river valley plains, and piedmont plains and deserts of inland basins in my country. However, when using a pump to extract groundwater for sample testing, it is necessary to first use a sludge removal cylinder to clear the silt accumulated in the well, open the channel for the pump to extract the sample, and prevent the pump from being blocked by silt. However, after the cylindrical sludge removal cylinder is inserted into the silt layer, the silt adheres to the inner wall of the sludge removal cylinder, making it difficult to remove the silt by bumping and knocking.

[0003] In view of this, we propose a highly efficient and portable dredging device for groundwater sampling. Utility Model Content

[0004] To address the problems mentioned in the background section, this application provides a highly efficient and portable dredging device for groundwater sampling.

[0005] The efficient and portable dredging equipment for groundwater sampling provided in this application adopts the following technical solution:

[0006] A high-efficiency, portable dredging device for groundwater sampling includes: a connecting rod, an abutment ring fixedly connected to the outside of the connecting rod and having an abutment groove, a wall sleeve A inserted outside the connecting rod, a wall sleeve B inserted outside the wall sleeve A, a fastening handwheel threadedly connected between the wall sleeve B and the wall sleeve A, one end of the fastening handwheel being able to be inserted into the abutment groove for limiting position, and a semi-ring shovel plate fixedly connected to one end of both the wall sleeve B and the wall sleeve A by a bolt structure, the two semi-ring shovel plates being slidably connected.

[0007] By adopting the above technical solution, the connecting rod, wall sleeve A and wall sleeve B are connected and limited by the fastening handwheel to form a dredging structure. After the fastening handwheel is removed, wall sleeve A and wall sleeve B can drive the fixedly installed semi-ring shovel plate to slide and adjust, which provides convenience for the sludge to be removed from the cylinder composed of the semi-ring shovel plate.

[0008] As an optional solution to the technical solution of this application, an annular groove is provided on one side of the abutment ring, a spring is fixedly connected in the annular groove, and a washer ring is fixedly connected to the other end of the spring.

[0009] By adopting the above technical solution, the spring is fixed in the annular groove on one side of the abutment ring, so that the spring can be tightly pressed against the outside of the wall sleeve B under the action of the washer ring, ensuring the tightness of the installation between the wall sleeve B, the wall sleeve A and the connecting rod.

[0010] As an optional solution to the technical solution of this application, a steel ring is fitted on the inner wall of the abutment groove, and the steel ring is configured with a C-shaped opening structure.

[0011] By adopting the above technical solution, the steel ring structure with a C-shaped opening can be flexibly fitted into the abutment groove, so that it abuts and limits the fastening handwheel, which can realize the rotational connection between the connecting rod and the wall sleeve, and improve the comfort of the device for gripping and lowering for dredging.

[0012] As an optional solution to the technical solution of this application, both the wall sleeve A and the wall sleeve B have slots in their grooves, and rubber columns with a trapezoidal structure are inserted into the slots.

[0013] By adopting the above technical solution, rubber columns with a trapezoidal structure are inserted into the slots of wall sleeve A and wall sleeve B. The rubber columns can fill the arc surface of the semi-ring shovel plate, ensuring the tightness of the connection between the semi-ring shovel plate and the wall sleeve.

[0014] As an optional solution to the technical solution in this application, a sloping groove is provided at one edge of the semi-circular shovel plate.

[0015] By adopting the above technical solution, and utilizing the inclined groove at one edge of the semi-circular shovel, the sharpness of the semi-circular shovel in contact with the silt can be improved.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. This application uses a fastening handwheel to connect and limit the connecting rod, wall sleeve A and wall sleeve B to form a dredging structure. After the fastening handwheel is removed, wall sleeve A and wall sleeve B can drive the fixedly installed semi-ring shovel plate to slide and adjust, which facilitates the removal of silt from the inside of the cylinder composed of the semi-ring shovel plate.

[0018] 2. This application utilizes a steel ring structure with a C-shaped opening that can be flexibly fitted into the abutment groove, allowing it to abut and limit the movement with the fastening handwheel. This enables a rotatable connection between the connecting rod and the wall sleeve, improving the comfort of holding and using the device for dredging. Attached Figure Description

[0030] This efficient and portable dredging device for groundwater sampling utilizes a C-shaped opening steel ring 31 that can be flexibly fitted into the abutment groove 3, allowing it to abut and limit the movement of the fastening handwheel 6. This enables a rotatable connection between the connecting rod 1 and the wall sleeve, improving the comfort of holding and using the device for dredging.

[0031] Reference Figure 2 and Figure 1 In the efficient and portable dredging equipment for groundwater sampling described in this application embodiment, slots are provided in the grooves of the wall sleeve A4 and the wall sleeve B5, and rubber columns 8 with trapezoidal structures are inserted into the slots.

[0032] This efficient and portable dredging device for groundwater sampling utilizes trapezoidal rubber columns 8 inserted into the slots of sleeve A4 and sleeve B5. The rubber columns 8 can fill the arc surface of the semi-ring shovel 7, ensuring a tight connection between the semi-ring shovel 7 and the sleeve.

[0033] Working principle: When using this device to clean and sample the inside of the well, first insert and connect the wall sleeve A4 and wall sleeve B5, which are equipped with the semi-ring shovel plate 7, to form a cylindrical structure.

[0034] Next, insert one end of the connecting rod 1 with the abutment groove 3 into the through-hole of the wall sleeve A4 and the wall sleeve B5, and thread the fastening handwheel 6 to the wall sleeve A4 and the wall sleeve B5 to limit its position, and fit the protruding fastening handwheel 6 into the abutment groove 3 to limit its position.

[0035] Then, the user can hold the connecting rod 1 and lower the device to perform the dredging operation;

[0036] Finally, when removing the silt attached to the semi-circular shovel plate 7, remove the fastening handwheel 6 and slide the wall sleeve A4 and wall sleeve B5 apart.
