Technical Field
[0001] This utility model relates to the field of sampling device technology, specifically a stratified sampling device for environmental engineering supervision. Background Technology
[0002] Environmental engineering supervision refers to the environmental protection supervision and management carried out by an environmental supervision agency on the construction of a project, entrusted by the project construction unit, based on the environmental impact assessment documents, the approval of the environmental protection administrative department, and the environmental supervision contract.
[0003] In environmental engineering supervision, monitoring and assessment of environmental factors such as soil and water quality are crucial aspects. Currently, some traditional water sampling devices only perform single-sample sampling. To accurately understand the water quality at different depths, it is necessary to perform stratified sampling of water samples from different layers. Traditional single-sample sampling requires multiple operations, which is time-consuming and labor-intensive. Therefore, a stratified sampling device for environmental engineering supervision is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a stratified sampling device for environmental engineering supervision to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a layered sampling device for environmental engineering supervision, including a base plate, wherein a sampling mechanism for water quality sampling is installed on the right side of the upper surface of the base plate;
[0006] The sampling mechanism includes a slide rail and a motor. The bottom of the slide rail is fixedly connected to the right side of the upper surface of the base plate. One end of the motor's output shaft is fixedly connected to a screw. The bottom end of the screw is rotatably connected to the right side of the upper surface of the base plate via a bearing. A nut seat is threadedly connected to the outer wall of the screw. The nut seat is slidably connected to the inner wall of the slide rail. A connecting plate is fixedly connected to the right side wall of the nut seat. A translation electric cylinder is mounted on one end of the piston rod of the connecting plate. A movable plate is fixedly connected to one end of the piston rod of the translation electric cylinder. A vertical rod is fixedly connected to the left side of the lower surface of the movable plate. A connecting block is uniformly fixedly connected to the right side wall of the upright, and a sampling cylinder is fixedly connected to the right end of the connecting block. A water inlet pipe is connected to the top of the right side wall of the sampling cylinder. A sealing electric cylinder is installed on the right side of the lower surface of the movable plate. A T-shaped block is fixedly connected to one end of the piston rod of the sealing electric cylinder. An installation plate is fixedly connected to the lower surface of the T-shaped block. A sleeve is uniformly fixedly connected to the left side wall of the installation plate. A sleeve rod is slidably connected to the inner side wall of the sleeve. A spring is fixedly connected between the right side wall of the sleeve rod and the inner right side wall of the sleeve. A conical rubber plug is fixedly connected to the left end of the sleeve rod.
[0007] As a further preferred embodiment of this technical solution: a bracket is fixedly connected to the upper surface of the slide rail, the top of the motor is mounted on the inner side wall of the bracket, a guide rail is fixedly connected to the middle of the lower surface of the movable plate, and the outer side wall of the T-shaped block is slidably connected to the inner side wall of the guide rail.
[0008] As a further preferred embodiment of this technical solution: the bottom of the front surface of the sampling tube is connected to a drain pipe, and a valve is installed on the outer wall of the drain pipe.
[0009] As a further preferred embodiment of this technical solution: two positioning blocks are symmetrically fixedly connected to the left side of the outer wall of the movable plate.
[0010] As a further preferred embodiment of this technical solution: two positioning rods are symmetrically fixedly connected to the right side wall of the connecting plate, and the positioning rods are slidably connected to the positioning block.

The electrical output terminal of the control panel is electrically connected to the electrical input terminal of the motor, the translation electric cylinder, and the sealing electric cylinder through wires.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This invention utilizes the extension of one end of the piston rod of a translational electric cylinder to move the sampling cylinder above the water surface to be sampled. A motor drives a screw to rotate clockwise, causing the nut seat to move downwards and submerge the sampling cylinder in the water. Simultaneously, the shortening of one end of the piston rod of a sealing electric cylinder moves a conical rubber stopper to the right, preventing it from blocking the inlet pipe. Water samples then enter the sampling cylinder along the inlet pipe, with samples from different depths entering their respective cylinders. The sealing electric cylinder then moves the conical rubber stopper to the right and inserts it into the inlet pipe. The spring force keeps the conical rubber stopper in contact with the inner wall of the inlet pipe, ensuring a tight seal. This allows for the extraction of water samples from different depths, enabling stratified sampling, saving time and effort, and bringing convenience to the sampling process.

[0026] Please see Figure 1-6 This utility model provides a technical solution: a layered sampling device for environmental engineering supervision, including a base plate 1, and a sampling mechanism 2 for water quality sampling is installed on the right side of the upper surface of the base plate 1;
[0027] The sampling mechanism 2 includes a slide rail 21 and a motor 23. The bottom of the slide rail 21 is fixedly connected to the right side of the upper surface of the base plate 1. One end of the output shaft of the motor 23 is fixedly connected to a screw 24. The bottom end of the screw 24 is rotatably connected to the right side of the upper surface of the base plate 1 through a bearing. A nut seat 25 is threadedly connected to the outer wall of the screw 24. The nut seat 25 is slidably connected to the inner wall of the slide rail 21. A connecting plate 26 is fixedly connected to the right side wall of the nut seat 25. A translation electric cylinder 27 is installed at one end of the piston rod of the connecting plate 26. A movable plate 28 is fixedly connected to one end of the piston rod of the translation electric cylinder 27. A vertical rod 29 is fixedly connected to the left side of the lower surface of the movable plate 28. The right side wall of the vertical rod 29 is uniformly fixed. A connecting block 210 is connected, and a sampling cylinder 211 is fixedly connected to the right end of the connecting block 210. A water inlet pipe 212 is connected to the top of the right side wall of the sampling cylinder 211. A sealing electric cylinder 213 is installed on the right side of the lower surface of the movable plate 28. A T-shaped block 214 is fixedly connected to one end of the piston rod of the sealing electric cylinder 213. An mounting plate 215 is fixedly connected to the lower surface of the T-shaped block 214. A sleeve 216 is evenly fixedly connected to the left side wall of the mounting plate 215. A sleeve rod 217 is slidably connected to the inner side wall of the sleeve 216.

A conical rubber plug 219 is fixedly connected to the left end of the sleeve rod 217.
[0028] Under the above configuration, the piston rod of the translation electric cylinder 27 extends to move the sampling cylinder 211 above the water surface to be sampled. The motor 23 drives the screw 24 to rotate clockwise, causing the nut seat 25 to move downward and submerge the sampling cylinder 211 in the water. The piston rod of the sealing electric cylinder 213 shortens to move the conical rubber plug 219 to the right, so that the conical rubber plug 219 no longer blocks the water inlet pipe 212. The water sample enters the sampling cylinder 211 along the water inlet pipe 212. Water samples at different depths enter the respective sampling cylinders 211. The sealing electric cylinder 213 then moves the conical rubber plug 219 to the right and inserts it into the water inlet pipe 212. The elastic force of the spring 218 pushes the conical rubber plug 219 to always fit against the inner wall of the water inlet pipe 212, ensuring a seal. Water samples at different depths can be taken out, achieving stratified sampling.
[0029] In this embodiment, specifically: a bracket 22 is fixedly connected to the upper surface of the slide rail 21, the top of the motor 23 is mounted on the inner side wall of the bracket 22, a guide rail 220 is fixedly connected to the middle of the lower surface of the movable plate 28, and the outer side wall of the T-block 214 is slidably connected to the inner side wall of the guide rail 220; this facilitates the guidance of the T-block 214 and improves the stability of the movement of the T-block 214.
[0030] In this embodiment, specifically: the bottom of the front surface of the sampling tube 211 is connected to a drain pipe 221, and a valve 222 is installed on the outer wall of the drain pipe 221; opening the valve 222 allows the water sample to flow out and be collected.
[0031] In this embodiment, specifically: two positioning blocks 223 are symmetrically fixedly connected to the left side of the outer wall of the movable plate 28; this facilitates the positioning blocks 223 and the movable plate 28 to move synchronously.
[0032] In this embodiment, specifically: two positioning rods 224 are symmetrically fixedly connected to the right side wall of the connecting plate 26, and the positioning rods 224 are slidably connected to the positioning block 223; the positioning rods 224 can provide guidance and support for the positioning block 223 and the movable plate 28.
[0033] In this embodiment, specifically: universal wheels 3 are evenly installed on the lower surface of the base plate 1, and a push handle 4 is fixedly connected to the left side wall of the base plate 1; to facilitate the movement of the base plate 1.
[0034] In this embodiment, specifically: a vertical plate 5 is fixedly connected to the front side of the upper surface of the base plate 1, and a control panel 6 is installed on the top of the front surface of the vertical plate 5. The electrical output terminal of the control panel 6 is electrically connected to the electrical input terminal of the motor 23, the translation electric cylinder 27 and the sealing electric cylinder 213 through wires, respectively, so as to facilitate the control of the working status of each electrical device.
[0035] The working principle of this utility model is as follows: The piston rod of the translational electric cylinder 27 extends, moving the sampling cylinder 211 above the water surface to be sampled. The motor 23 drives the screw 24 to rotate clockwise, causing the nut seat 25 to move downwards, submerging the sampling cylinder 211 in the water. The piston rod of the sealing electric cylinder 213 shortens, moving the conical rubber plug 219 to the right, preventing it from blocking the inlet pipe 212. Water samples enter the sampling cylinder 211 along the inlet pipe 212. Water samples at different depths enter their respective sampling cylinders 211. The sealing electric cylinder 213 then moves the conical rubber plug 219 to the right, inserting it into the inlet pipe 212. The spring force of the spring 218 pushes the conical rubber plug 219 to always adhere to the inner wall of the inlet pipe 212, ensuring a tight seal. This allows for the extraction of water samples at different depths, achieving layered sampling, saving time and effort, and bringing convenience to the sampling process.
