Description

Technical Field

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

[0002] In today's society, environmental protection has become a global focus, and the sampling and testing of water quality in lakes is a crucial part of environmental protection work. Accurately and efficiently obtaining water samples from different depths is of key significance for comprehensively assessing the environmental conditions, pollution levels, and ecological health of lakes and other water bodies.

[0003] Traditional water samplers typically consist of a cylindrical container with a valve, along with counterweights, ropes, and other components. In use, they are submerged in water, and the sampler is brought to a predetermined depth by adjusting the counterweight or releasing the rope, triggering the valve to collect a water sample. While capable of collecting samples from a specific depth, they can only collect one sample at a time. Furthermore, the operation requires manual control of the rope's extension and retrieval, making the process relatively cumbersome and inefficient when collecting multiple samples from different depths.

[0004] Therefore, there is a need to provide an environmental protection water sampling device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an environmental protection water sampling device to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an environmental protection water sampling device, comprising:

[0007] spheres;

[0008] Test tubes arranged in a circular array within a spherical block;

[0009] A sealing block is rotatably mounted on the top of the sphere and abuts against the port of the test tube. The sealing block has a through hole that is connected to the test tube.

[0010] A clamping assembly, comprising at least clamping blocks symmetrically arranged within a spherical block and rotatably engaged, the inner wall of the clamping blocks abutting against a test tube.

[0011] Preferably, the sidewall of the sphere is provided with mounting grooves arranged in a circular array, and test tubes are fixedly connected in the mounting grooves.

[0012] Preferably, the ball block has grooves arranged in a circular array inside, the grooves are connected to the mounting groove, the rotating shafts are symmetrically arranged inside the grooves, and clamping blocks are fixedly connected to the side walls of the rotating shafts.

[0013] Preferably, a torsion spring is fixedly installed at the bottom end of the rotating shaft, and one end of the torsion spring is fixedly connected to the ball block.

[0014] Preferably, the inner wall of the sealing block is provided with a toothed groove.

[0015] Preferably, an electric motor is fixedly installed at the top of the ball, and a gear is fixedly installed on the output end of the electric motor, the gear meshing with a tooth groove.

[0016] Preferably, a counterweight is fixedly installed at the bottom end of the ball.

[0017] The environmental protection water sampling device provided by this utility model, as described above, has the following beneficial effects:

[0018] This invention, by incorporating a spherical block, test tubes, a sealing block, a through-hole, and a clamping block, facilitates the collection of water samples from lakes at different depths. By dropping the spherical block into the water, it floats in the shallow water. Rotating the sealing block connects the through-hole to one of multiple test tubes, allowing shallow water samples to flow into the test tube for collection. As the test tube fills with shallow water, its weight increases, causing the spherical block to sink to deeper water. Continuous rotation of the sealing block causes the through-hole to detach from the full test tube and move towards an adjacent empty test tube. This allows multiple test tubes within the spherical block to follow its position, collecting water samples from different depths. The process is simple and allows for the simultaneous collection of multiple samples from different depths, significantly improving the efficiency of water sample collection at various depths.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-4 As shown, an environmental protection water sampling device includes:

[0028] Ball 1;

[0029] Test tubes 3 arranged in a circular array within spherical block 1;

[0030] A sealing block 4 is rotatably mounted on the top of the ball block 1 and abuts against the port of the test tube 3. The sealing block 4 has a through hole 5, which is connected to the test tube 3.

[0031] The clamping assembly includes at least one clamping block 11 symmetrically arranged inside the ball block 1 and rotatably engaged, with the inner wall of the clamping block 11 abutting against the test tube 3.

[0032] Specifically, when water samples need to be collected from different depths in the lake, test tube 3 is inserted into ball block 1, and clamping block 11 is driven to clamp test tube 3, allowing test tube 3 to be installed inside ball block 1. After test tube 3 is installed, ball block 1 is tied to one end of a rope and then thrown into the water, allowing ball block 1 to enter the water for water sample collection. When ball block 1 enters the water, it will float in the shallower part of the lake. By driving sealing block 4 to rotate clockwise, the through hole 5 on sealing block 4 and ball block 1 are connected. The test tubes 3 installed inside block 1 are connected, allowing shallow water samples to flow into and be collected. By continuously driving the sealing block 4 to rotate, the through hole 5 disengages from the first test tube 3 and rotates towards the adjacent second test tube 3. The water samples collected in the test tubes 3 increase the weight of the sphere 1, causing the sphere 1 to descend into deeper water layers after each test tube 3 has collected water samples at different depths. This allows multiple test tubes 3 to cooperate with the through holes 5 on the sealing block 4 to collect water samples at different depths.

[0033] In the above embodiment, by throwing the ball block 1 into the water, the ball block 1 can float in the shallow area of ​​the water. By driving the sealing block 4 to rotate, the through hole 5 is connected to one of the multiple test tubes 3, so that the shallow water sample can flow into the test tube 3 through the through hole 5 for collection. As the test tube 3 is filled with shallow water sample, the weight of the test tube 3 increases, which in turn increases the weight of the ball block 1 and causes it to sink into the deeper water. By continuously driving the sealing block 4 to rotate, the through hole 5 is disengaged from the test tube 3 filled with water sample and moves to the adjacent empty test tube 3. This allows the multiple test tubes 3 installed in the ball block 1 to follow the position of the ball block 1 and collect water samples at different depths. This not only simplifies the operation process but also allows for the collection of multiple water samples at different depths at once, improving the collection efficiency of water samples at different depths.

[0034] As a further embodiment of this utility model, the side wall of the sphere 1 is provided with mounting grooves 2 arranged in a circular array, and a test tube 3 is fixedly connected in the mounting grooves 2.

[0035] Furthermore, the ball block 1 has grooves 9 arranged in a circular array inside, the grooves 9 are connected to the mounting groove 2, and the rotating shafts 10 are symmetrically arranged inside the grooves 9. Clamping blocks 11 are fixedly connected to the side wall of the rotating shafts 10.

[0036] Furthermore, a torsion spring 13 is fixedly installed at the bottom of the rotating shaft 10, and one end of the torsion spring 13 is fixedly connected to the ball block 1.

[0037] Specifically, when test tube 3 needs to be installed into ball block 1, it is interconnected with mounting groove 2 through groove 9, so that clamping block 11 installed in groove 9 can extend into mounting groove 2. By inserting test tube 3 into mounting groove 2, test tube 3 pushes clamping block 11 to open as it moves into mounting groove 2. Clamping block 11 drives rotating shaft to rotate, causing rotating shaft to drive torsion spring 13 to deform, so that clamping block 11 can clamp test tube 3 in mounting groove 2. When test tube 3 needs to be removed from mounting groove 2, it can be pulled out of mounting groove 2 by turning clamping block 11 to open.

[0038] As another embodiment further provided in this utility model, a toothed groove 6 is provided on the inner wall of the sealing block 4.

[0039] Furthermore, a motor 7 is fixedly installed on the top of the ball block 1, and a gear 8 is fixedly installed on the output end of the motor 7, which meshes with the gear tooth groove 6.

[0040] Specifically, when the ball block 1 with test tube 3 installed enters the water, the motor 7 drives the gear 8 to rotate, so that the gear 8 and the tooth groove 6 cooperate to drive the sealing block 4 to rotate, so that the through hole 5 opened on the sealing block 4 can connect with different test tubes 3 during the rotation, thereby improving the efficiency of multi-layer water sample collection.

[0041] As another embodiment of this utility model, a counterweight 12 is fixedly installed at the bottom end of the ball block 1.

[0042] Specifically, by installing a counterweight 12 at the bottom of the ball block 1, the ball block 1 can always remain balanced, preventing the ball block 1 from flipping over during the water sample collection process, thus affecting the water sample collection effect.

[0043] Working principle: By inserting test tube 3 into installation slot 2, test tube 3 pushes clamping block 11 to open during installation. The deformation of torsion spring 13 provides rotational force to the rotating shaft, causing the rotating shaft to drive the symmetrically arranged clamping blocks 11 to cooperate and hold test tube 3. After test tube 3 is installed, ball block 1 is tied with a rope and thrown into the water, allowing ball block 1 to sink to the shallow water layer according to its own weight. The motor 7 drives gear 8 to rotate, and gear 8 cooperates with gear tooth groove 6 to drive sealing block 4 to rotate continuously. During the rotation, through hole 5 is connected to test tube 3, allowing shallow water samples to be collected in test tube 3. After the water sample enters test tube 3, the weight of ball block 1 increases and the buoyancy decreases, allowing ball block 1 to sink to the deeper water layer. During the descent of ball block 1, through hole 5 is connected to different test tubes 3, allowing multiple test tubes 3 to collect water samples at different depths. After the water sample collection is completed, ball block 1 is pulled out with a rope.

[0044] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
