Description

Technical Field

[0001] This utility model relates to the field of environmental engineering technology, specifically to an environmental geological water sampling device. Background Technology

[0002] Environmental engineering is a discipline that studies how to protect and rationally utilize natural resources, uses scientific methods to solve increasingly serious environmental problems, and promotes environmental protection and social development. Water, as a basic natural resource, plays a vital role in people's production activities, and the quality of drinking water is closely related to human health. Therefore, people have increasingly higher requirements for water quality. Water sampling is required when testing water quality. Water sampling requires water sampling devices. After sampling, its components are analyzed, and finally, the test results are obtained.

[0003] A search revealed a Chinese patent publication dated January 5, 2024, with publication number CN220304906U, describing a water sampling device. The device comprises a mounting block, a fixed pipe fixedly connected to the lower end of the mounting block, a lifting pipe inserted inside the fixed pipe, a collection box snapped onto the lower end of the lifting pipe, collection chambers evenly spaced within the collection box, vertical air vents vertically formed inside the collection box, and interconnected collection chambers via these air vents. A waterproof and breathable membrane is fixedly installed inside each air vent. A water inlet is located on one side of each collection chamber, with a one-way valve fixedly installed inside. An outlet is located on the other side of each collection chamber. An air pump is fixedly installed at the upper end of the mounting block. This invention allows for simultaneous sampling of water at different depths by moving the lifting pipe, and the sampling box can be installed and disassembled using a sliding limit frame. It is simple and convenient to operate, easy to carry, and highly practical.

[0004] Although the existing technical solutions described above can simultaneously sample water at different depths by moving the lifting pipe and can install and disassemble the sampling box by using the sliding limit frame, they are not convenient for sampling water at different depths at the same time. When sampling water at different depths, repeated operations are required, which reduces work efficiency. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides an environmental geological water sampling device to solve the problems mentioned in the background technology, such as the inconvenience of simultaneously sampling water at different depths and the need for repeated operations when sampling water at different depths, which reduces work efficiency.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an environmental geological water sampling device, comprising a mounting base and three water sampling boxes. A fixed square tube is fixedly connected to the bottom end of the mounting base. A first sliding tube is slidably connected inside the fixed square tube. A first mounting tube is provided at one end of the first sliding tube. A second sliding tube is slidably connected inside the first sliding tube. A second mounting tube is provided at one end of the second sliding tube. Toothed plates are provided on the outer walls of both the first and second sliding tubes. Through holes are opened near the bottom ends of the fixed square tube and the first mounting tube. Tension springs are fixedly connected to the outer walls of both the fixed square tube and the first mounting tube. A connecting plate is provided at one end of the tension spring. One end of the connecting plate is provided with a toothed block that mates with the toothed plate. The toothed block is slidably connected to the through hole. The outer walls of the fixed square tube, the first mounting tube, and the second mounting tube are all fixedly connected with a fixed frame that mates with the water collection box. A rotating handle is rotatably connected to the fixed frame. One end of the rotating handle passes through the fixed frame and is connected to a positioning bar. One end of each of the three water collection boxes is fixedly connected with a connecting frame. One end of the connecting frame is provided with a through groove that mates with the positioning bar. The top of each water collection box is provided with a water inlet hole. An electric push rod is installed on the inner lower side wall of each water collection box. The top of the electric push rod is provided with a sealing plate that mates with the water inlet hole. The top of the mounting base is provided with a control button that mates with the three electric push rods.

[0009] By adopting the above technical solution, the positioning bar passes through the slot, and rotating the rotating handle drives the positioning bar to rotate, thereby making the positioning bar snap into the inside of the connecting frame, thus connecting the water collection box to the fixed frame. Pulling the two connecting plates drives the two toothed blocks to move, thereby causing the toothed blocks to disengage from the toothed plates. At this time, the first and second mounting cylinders can be pulled to move, thereby adjusting the distance between the three water collection boxes. The equipment is then submerged in water, and the control button is pressed, causing the three electric push rods to simultaneously drive the three sealing plates to disengage from the water inlet, thereby enabling the three water collection boxes to take samples. This facilitates simultaneous sampling of water at different depths, thereby improving work efficiency.

[0010] Optionally, both the first and second sliding cylinders have graduations on their outer walls.

[0011] By adopting the above technical solution, the scale is used to facilitate personnel to observe the moving distance of the first and second sliding cylinders, thereby making it easier to accurately adjust the distance between the three water collection boxes.

[0012] Optionally, each of the three mounting brackets is fixedly connected with a limiting bracket that cooperates with the water collection box.

[0013] By adopting the above technical solution, the limiting bracket is used to limit the water collection box when it is connected to the fixed frame, so as to prevent the water collection box from shaking or tilting, thereby improving the stability of the equipment.

[0014] Optionally, each of the water inlets is equipped with a filter screen.

[0015] By adopting the above technical solution, the filter screen is used to filter out impurities and sediment during water sampling, preventing impurities from entering the water sampling box, thereby improving the purity of the sample.

[0016] Optionally, the top of the mounting base is fixedly connected to an anti-accidental touch frame that cooperates with the control button.

[0017] By adopting the above technical solution, the anti-accidental touch frame is used to reduce the probability of accidental touch of control buttons, thereby improving the stability of the equipment.

[0018] (III) Beneficial Effects

[0019] In summary, this utility model has at least one of the following beneficial technical effects:

[0020] This environmental geological water sampling device involves passing a positioning bar through a slot and rotating a handle to rotate the positioning bar, causing it to engage inside the connecting frame. This connects the water sampling box to the fixed frame. Pulling the two connecting plates moves two toothed blocks, disengaging them from the toothed plates. At this point, the first and second mounting cylinders can be pulled to adjust the distance between the three water sampling boxes. When the device is submerged in water and the control button is pressed, three electric push rods simultaneously move three sealing plates away from the inlet holes, allowing the three water sampling boxes to take samples. This facilitates simultaneous sampling of water at different depths, improving work efficiency. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1-4 An environmental geological water sampling device includes a mounting base 1, three water sampling boxes 2, a fixed square tube 3 fixedly connected to the bottom of the mounting base 1, a first sliding tube 4 slidably connected inside the fixed square tube 3, a first mounting tube 5 at one end of the first sliding tube 4, a second sliding tube 6 slidably connected inside the first sliding tube 4, a second mounting tube 7 at one end of the second sliding tube 6, toothed plates 8 on the outer walls of both the first sliding tube 4 and the second sliding tube 6, and through holes near the bottom of the fixed square tube 3 and the first mounting tube 5. Tension springs 9 are fixedly connected to the outer walls of the fixed square tube 3 and the first mounting tube 5. One end of the tension spring 9 is provided with a connecting plate 10, and one end of the connecting plate 10 is provided with a toothed block 11 that mates with the toothed plate 8. The toothed block 11 is slidably connected to the through hole. Fixing frames 12 that mate with water collection boxes 2 are fixedly connected to the outer walls of the fixed square tube 3, the first mounting tube 5, and the second mounting tube 7. A rotating handle 13 is rotatably connected to the fixing frame 12. One end of the rotating handle 13 passes through the fixing frame 12 and is connected to a positioning bar 14. One end of each of the three water collection boxes 2 is fixedly connected to... A connecting frame 15 has a through groove at one end that mates with a positioning rod 14. A water inlet is located at the top of the water dispenser 2. An electric push rod 16 is mounted on the lower inner side wall of the water dispenser 2. A sealing plate 17 mates with the water inlet is located at the top of the electric push rod 16. A control button 18 mates with the three electric push rods 16 is located at the top of the mounting base 1. The positioning rod 14 is passed through the through groove, and the rotating handle 13 is rotated to make the positioning rod 14 engage inside the connecting frame 15, thereby dispensing water. Box 2 is connected to the fixed frame 12. Pulling the two connecting plates 10 moves the two toothed blocks 11, thereby causing the toothed blocks 11 to disengage from the toothed plate 8. At this time, the first mounting cylinder 5 and the second mounting cylinder 7 can be pulled to move, thereby adjusting the distance between the three water collection boxes 2. The device is then submerged in the water. Pressing the control button 18 causes the three electric push rods 16 to simultaneously drive the three sealing plates 17 to disengage from the water inlet, thereby enabling the three water collection boxes 2 to take samples. This facilitates simultaneous sampling of water at different depths, thereby improving work efficiency.

[0029] Reference Figure 2 and Figure 3 The outer walls of the first sliding cylinder 4 and the second sliding cylinder 6 are both provided with scales 19. The scales 19 are used to facilitate personnel to observe the moving distance of the first sliding cylinder 4 and the second sliding cylinder 6, so as to facilitate accurate adjustment of the distance between the three water collection boxes 2.

[0030] Reference Figures 1-3 Each of the three fixed frames 12 is fixedly connected with a limiting bracket 20 that cooperates with the water collection box 2. The limiting bracket 20 is used to limit the water collection box 2 when it is connected to the fixed frame 12, so as to prevent the water collection box 2 from shaking or tilting, thereby improving the stability of the equipment.

[0031] Reference Figure 2 and Figure 3 Each water inlet is equipped with a filter screen 21. The filter screen 21 is used to filter out impurities and sediment during water sampling to prevent impurities from entering the water sampling box 2, thereby improving the purity of the sample.

[0032] Reference Figure 1 The top of the mounting base 1 is fixedly connected to an anti-accidental touch frame 22 that cooperates with the control button 18. The anti-accidental touch frame 22 is used to reduce the probability of accidental touch of the control button 18, thereby improving the stability of the equipment.

[0033] In summary, the working principle and process of this environmental geological water sampling device are as follows: First, the positioning bar 14 is passed through the through slot. Rotating the rotating handle 13 causes the positioning bar 14 to rotate, thus engaging it inside the connecting frame 15. This connects the water sampling box 2 to the fixed frame 12. Pulling the two connecting plates 10 moves the two toothed blocks 11, causing them to disengage from the toothed plates 8. At this point, the first mounting cylinder 5 and the second mounting cylinder 7 can be pulled to adjust the distance between the three water sampling boxes 2. The device is then submerged in water. Pressing the control button 18 causes the three electric push rods 16 to simultaneously move the three sealing plates 17 away from the water inlet, allowing the three water sampling boxes 2 to take samples. This facilitates simultaneous sampling of water at different depths, thereby improving work efficiency. Scale 19 allows personnel to easily observe the movement distance of the first sliding cylinder 4 and the second sliding cylinder 6, facilitating accurate adjustment of the distance between the three water collection boxes 2. The limiting bracket 20 limits the water collection box 2 when it is connected to the fixed frame 12, preventing it from shaking or tilting, thus improving equipment stability. The filter screen 21 filters out impurities and sediment during water sampling, preventing them from entering the water collection box 2, thereby improving sample purity. The anti-accidental touch frame 22 reduces the probability of accidental touch of the control button 18, thus improving equipment stability.

[0034] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
