Description

Technical Field

[0001] This utility model relates to the technical field of water quality sampling equipment, and in particular to a portable water quality sampling device for environmental protection acceptance. Background Technology

[0002] Water sampling is an important part of environmental protection acceptance work, and accurate water samples are crucial for assessing the quality of the water environment.

[0003] Traditional water sampling devices are large and complex, making them inconvenient to carry. When sampling water bodies at different locations is required, staff need to expend considerable effort to move the equipment, increasing the difficulty and labor intensity of the work. Moreover, many devices struggle to achieve fixed-depth sampling during the sampling process, failing to accurately obtain water samples at specific depths. This results in sampling results that do not accurately reflect the actual conditions of water bodies at different depths, affecting the accuracy and reliability of environmental protection acceptance work. Utility Model Content

[0004] The main purpose of this utility model is to provide a portable water quality sampling device for environmental protection acceptance, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a portable water quality sampling device for environmental protection acceptance, comprising a sampling tube, a one-way valve provided in the lower middle part of the sampling tube, a sampling mechanism provided in the middle part of the sampling tube, a storage cover threadedly connected to the lower outer circumference of the sampling tube, an inflatable float, two pull ropes and two spring hooks provided inside the storage cover, the spring hooks being fixedly connected to one end of the pull ropes, the middle part of the inflatable float being fixedly connected to the other end of one of the pull ropes, a release mechanism provided at the upper part of the sampling mechanism, a first lifting ring provided on the outer circumference of the sampling tube, a second lifting ring provided at the lower part of the release mechanism, a counterweight provided at the upper part of the sampling mechanism, and a drain valve provided on the lower side wall of the sampling tube.

[0006] Preferably, a handle is provided at the center of the outer periphery of the sampling cylinder.

[0007] Preferably, one of the spring hooks is connected to one of the lifting rings, and the other spring hook is connected to another of the lifting rings.

[0008] Preferably, the sampling mechanism includes a limiting plate, a bracket, a connecting rod, a piston, and a compression spring. The outer periphery of the piston is slidably connected to the inside of the sampling cylinder. The outer periphery of the bracket is fixedly connected to the upper end of the sampling cylinder. The lower end of the connecting rod is fixedly connected to the middle of the piston. The upper part of the connecting rod is slidably connected to the middle of the bracket. The middle part of the limiting plate is fixedly connected to the upper end of the connecting rod. The middle part of the counterweight is fixedly connected to the middle of the limiting plate. The compression spring is sleeved on the outer periphery of the connecting rod and is disposed between the limiting plate and the bracket.

[0009] Preferably, the release mechanism includes a connecting ring, a connecting rod, and locking rods. The middle portions of the locking rods are rotatably connected to the upper part of the bracket at equal intervals via torsion springs. The upper ends of the locking rods are disposed on the upper part of the limiting plate, and the lower ends of the locking rods are rotatably connected to the upper ends of the connecting rods. The lower ends of the connecting rods are rotatably connected to the upper part of the connecting ring at equal intervals.

[0010] Preferably, the upper part of the bracket is provided with multiple limiting blocks, and each limiting block corresponds to a locking rod.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. When not in use, deflate the air inside the inflatable float and fold it. Then remove the spring hook from the first and second lifting rings. Finally, place the spring hook, rope, and inflatable float inside the storage cover. Screw the storage cover onto the bottom of the sampling tube to store it. The device can be easily carried by using the handle.

[0013] 2. After assembling the device, adjust the length of the pull rope connected to the inflatable float as needed, then drop the device into the water. The sampling cylinder sinks into the water under the action of the counterweight, while the inflatable float floats on the water surface. Finally, the inflatable float pulls the connecting ring through the pull rope and the lifting ring, which in turn pulls the locking rod through the connecting rod, causing the locking rod to release the limiting plate. Under the action of gravity and the compression spring, the connecting rod pulls the piston, making the inside of the sampling cylinder negative pressure. This allows water from the outside to enter the sampling cylinder through the one-way valve, thereby completing the fixed-depth sampling and ensuring the accuracy and reliability of environmental protection acceptance work.

[0021] Specifically, when not in use, deflate the air inside the inflatable float 10 and fold it. Then, remove the spring hook 8 from the first and second lifting rings 5 ​​and 7. Finally, place the spring hook 8, the pull rope 9, and the inflatable float 10 inside the storage cover 11. Finally, screw the storage cover 11 onto the lower part of the sampling cylinder 1 to store the sampling cylinder 1. The device can be easily carried using the handle 6.

[0022] In this embodiment, the sampling mechanism 2 includes a limiting disk 201, a bracket 202, a connecting rod 203, a piston 204, and a compression spring 205. The outer periphery of the piston 204 is slidably connected to the inside of the sampling cylinder 1. The outer periphery of the bracket 202 is fixedly connected to the upper end of the sampling cylinder 1. The lower end of the connecting rod 203 is fixedly connected to the middle part of the piston 204, and the upper part of the connecting rod 203 is slidably connected to the middle part of the bracket 202. The middle part of the limiting disk 201 is fixedly connected to the upper end of the connecting rod 203. The middle part of the counterweight 3 is fixedly connected to the middle part of the limiting disk 201. The compression spring 205 is sleeved on the connecting rod 204. 03. On the outer periphery, a compression spring 205 is disposed between the limiting plate 201 and the bracket 202. The release mechanism 4 includes a connecting ring 401, a connecting rod 402, and a locking rod 403. The middle parts of multiple locking rods 403 are rotatably connected to the upper part of the bracket 202 by torsion springs at equal intervals.

[0023] Specifically, after assembling the device, adjust the length of the pull rope 9 connected to the inflatable float 10 as needed, then drop the device into the water. The sampling cylinder 1 sinks into the water under the action of the counterweight 3, while the inflatable float 10 floats on the water surface.

Finally, pull the pull rope 9 in your hand to take the device out of the water.

[0024] Working principle:

[0025] In use, unscrew the storage cover 11, remove the spring hook 8, pull rope 9, and inflatable float 10.

Connect one end of the other pull rope 9 to the first lifting ring 5 via the spring hook 8, and hold the other end of the pull rope 9. Adjust the length of the pull rope 9 connected to the inflatable float 10 as needed. Then, drop the device into the water. The sampling cylinder 1 sinks into the water under the action of the counterweight 3, while the inflatable float 10 floats. Floating on the water surface, the inflatable float 10 will pull the connecting ring 401 through the pull rope 9 and the second lifting ring 7, which will pull the locking rod 403 through the connecting rod 402, causing the locking rod 403 to release the limiting plate 201. Under the action of gravity and the compression spring 205, the connecting rod 203 will pull the piston 204, making the inside of the sampling cylinder 1 negative pressure, so that the outside water enters the sampling cylinder 1 through the one-way valve 12, thereby completing the fixed-depth sampling. Finally, pull the pull rope 9 in your hand to take the device out of the water.
