Description

Technical Field

[0001] This utility model relates to the field of groundwater pollution detection technology, specifically a sampler for groundwater pollution detection. Background Technology

[0002] Groundwater pollution monitoring refers to the monitoring and determination of the types, concentrations, and changing trends of harmful substances in groundwater, evaluating and understanding the state of groundwater pollution, and assessing the status and development trends of groundwater quality and pollution. Monitoring items generally include: ammonia nitrogen, nitrite nitrogen, nitrate nitrogen, total hardness, pH value, oxygen consumption, total mineralization, potassium, sodium, calcium, magnesium, bicarbonate, sulfate, chloride ions, phenols, cyanide, mercury, arsenic, cadmium, total chromium, fluoride, oils, coliform bacteria, and total bacterial count. Groundwater pollution monitoring is the foundation of groundwater environmental research. The reliability of groundwater environmental monitoring directly affects groundwater environmental assessment, our objective understanding of groundwater environmental changes, and the formulation of major decisions. Groundwater pollution detection samplers are specialized equipment used to collect groundwater samples. Their core function is to ensure that the collected water samples are representative, accurate, and free of pollution, providing a reliable basis for subsequent water quality analysis.

[0003] Some existing groundwater pollution detection samplers first place the Bayle tube into the groundwater monitoring well when sampling groundwater. Then, the Bayle tube is lowered through a rope by rotating the take-up and release roller clockwise. The sample is then collected through the Bayle tube, and then the take-up and release roller is rotated counterclockwise to rewind the sample.

[0004] Existing samplers for groundwater pollution detection have the following problems: when sampling groundwater, the rope is irregularly wound around the outside of the take-up roller. This irregular winding can easily cause the rope to accumulate and knot on the take-up roller, which will affect the next use and reduce the efficiency of groundwater sampling. Therefore, we propose a sampler for groundwater pollution detection. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a sampler for groundwater pollution detection. When sampling groundwater, the rope can be neatly wound up and down, avoiding irregular tangling that causes the rope to accumulate and knot on the take-up roller, which will not affect the next use and will improve the efficiency of groundwater sampling. This can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sampler for detecting groundwater pollution, including a base, a support plate provided on the rear side of the upper end of the base, a take-up roller rotatably connected to the front side of the support plate via a rotating shaft, a rope wound around the outer wall of the take-up roller, a belle tube provided at the right end of the rope, and a regular winding mechanism.

[0007] The orderly winding mechanism includes a slide rail, a slider, a support block, a support rod, and a chuck. An L-shaped bracket is provided at the upper edge of the support plate. A slide rail is provided on the left side wall of the L-shaped bracket. A slider is slidably connected inside the slide rail. A support block is provided at the right end of the slider. A support rod is provided at the right end of the support block. A chuck is provided at the right end of the support rod. The chuck is installed in conjunction with the rope. When sampling groundwater, the rope can be orderly wound up and down, avoiding irregular tangling that would cause the rope to accumulate or knot on the take-up roller, thus not affecting the next use and improving the efficiency of groundwater sampling.

[0008] Furthermore, the winding mechanism also includes a slide bar, which is fixedly connected to the lower side between the front and rear inner walls of the L-shaped bracket. The sliding hole in the middle of the support block is slidably connected to the outer surface of the slide bar, which facilitates improved sliding support.

[0009] Furthermore, the winding mechanism also includes a rotating column and a wave groove. The rotating column is rotatably connected to the upper side between the front and rear inner walls of the L-shaped bracket. The outer surface of the rotating column is provided with a wave groove. The inner wall of the wave groove is slidably connected to the outer surface of the small support block at the upper end of the support block to provide guidance.

[0010] Furthermore, the winding mechanism also includes sprockets and chains. The rear end of the rotating column and the rear end of the rotating shaft are respectively fixedly connected to sprockets, and the two sprockets are connected by chain drive to provide rotational connection.

[0011] Furthermore, the rear end of the support plate is provided with a protective cover, and the sprocket and chain are both located within the protective cover for easy protection.

[0012] Furthermore, a knob is rotatably connected to the edge of the front side of the take-up roller to facilitate the winding and unwinding of the rope.

[0013] Furthermore, the upper end of the base is provided with a Baylor tube placement box, which is installed in conjunction with the Baylor tube to facilitate the placement of the Baylor tube.

[0014] Furthermore, the upper end of the L-shaped bracket is provided with a handle for easy handling.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the local groundwater pollution detection sampler has the following advantages:

[0016] By turning the knob, the take-up roller and rotating shaft drive the sprocket and chain drive to rotate the rotating column. The rotating column guides the small support block through the wave groove, allowing the slider to slide left and right within the slide rail. Under the sliding support of the slide rod, the support block drives the rope to be neatly wound around the outside of the take-up roller during the winding process through the support rod and the dial ring. When sampling groundwater, the rope can be neatly wound and unwound, avoiding irregular winding that would cause the rope to accumulate or knot on the take-up roller, thus not affecting the next use and improving the efficiency of groundwater sampling.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4This embodiment provides a technical solution: a sampler for groundwater pollution detection, including a base 1, a support plate 2 on the rear side of the upper end of the base 1, a take-up roller 4 rotatably connected to the front side of the support plate 2 via a rotating shaft, a rope 6 wound around the outer wall of the take-up roller 4, the left end of the rope 6 fixedly connected to the outer wall of the take-up roller 4, and a Belle tube 7 at the right end of the rope 6. It also includes a winding mechanism 8, a knob 5 rotatably connected to the edge of the front side of the take-up roller 4, a Belle tube placement box 9 at the upper end of the base 1, the Belle tube placement box 9 and the Belle tube 7 being installed together, and a handle 10 at the upper end of an L-shaped bracket 3. When sampling groundwater, the Belle tube 7 is first taken out of the Belle tube placement box 9, then placed in the water, and then the knob 5 is rotated. Knob 5 drives the take-up roller 4 to rotate around the rotating shaft on the support plate 2, realizing the take-up and release of the rope 6 wrapped on the outer wall of the take-up roller 4, thereby controlling the raising and lowering of the right end of the Belle tube 7. When the Belle tube 7 sinks below the groundwater level, due to water pressure, the ball check valve at its bottom opens. At this time, groundwater flows into the pipe from the upper inlet of the Belle tube 7 under the action of gravity. When the Belle tube 7 is full of water sample or reaches the predetermined sampling volume, the sampling personnel pull up the Belle tube 7. As the Belle tube 7 is lifted, the ball check valve at the bottom closes under the action of gravity of the water, preventing the water sample from flowing out, thereby sealing the groundwater sample in the Belle tube 7, completing the groundwater sample collection. After the collection is completed, the Belle tube 7 is placed in the Belle tube placement box 9 for storage by holding the handle 10 of the transport device.

[0024] The winding mechanism 8 includes a slide rail 803, a slider 804, a support block 805, a support rod 807, and a deflector ring 808. An L-shaped bracket 3 is located at the upper edge of the support plate 2. A slide rail 803 is located on the left side wall of the L-shaped bracket 3. A slider 804 is slidably connected inside the slide rail 803. A support block 805 is located at the right end of the slider 804. A support rod 807 is located at the right end of the support block 805. A deflector ring 808 is located at the right end of the support rod 807. The deflector ring 808 is installed in conjunction with the rope 6. The winding mechanism 8 also includes a slide rod 806. The slide bar 806 is fixedly connected to the lower side between the front and rear inner walls of the L-shaped bracket 3. The sliding hole in the middle of the support block 805 is slidably connected to the outer surface of the slide bar 806. The winding mechanism 8 also includes a rotating column 801 and a wave groove 802. The rotating column 801 is rotatably connected to the upper side between the front and rear inner walls of the L-shaped bracket 3. The outer surface of the rotating column 801 is provided with a wave groove 802. The inner wall of the wave groove 802 is slidably connected to the outer surface of the small support block at the upper end of the support block 805. The winding mechanism 8 also includes a sprocket 809 and a chain 810. The rear end of the rotating column 801 and the rear end of the rotating shaft are respectively fixedly connected to sprockets 809. The two sprockets 809 are connected by a chain 810. The rear end of the support plate 2 is provided with a protective cover 11. Both the sprockets 809 and the chain 810 are located in the protective cover 11. When the Belle tube 7 is lifted, the knob 5 is rotated counterclockwise. The knob 5 drives the take-up roller 4 to rotate around the rotating shaft on the support plate 2, which in turn drives the rotating shaft to rotate. The rotation of the rotating shaft will drive the rotating column 801 to rotate through the transmission of the sprockets 809 and the chain 810. The inner wall of the wave groove 802 on the outer surface of the rotating column 801 is slidably connected to the outer surface of the small support block at the upper end of the support block 805. During the rotation of the rotating column 801, the small support block is guided by the wave groove 802 and slides left and right in the slide rail 803 on the left side wall of the L-shaped bracket 3 via the slider 804. At the same time, the sliding hole in the middle of the support block 805 slides along the slide rod 806. The sliding of the support block 805 drives the support rod 807 and the right end dial ring 808 to move. The dial ring 808 drives the wire to be neatly wound around the outside of the take-up roller 4 during the winding process, so as to avoid tangling during the next use.

[0025] The working principle of the sampler for groundwater pollution detection provided by this utility model is as follows: When sampling groundwater, first, the Belle tube 7 is taken out from the Belle tube placement box 9, then the Belle tube 7 is placed in the water. Next, the knob 5 is rotated, which drives the take-up roller 4 to rotate around the rotating shaft on the support plate 2, realizing the take-up and release of the rope 6 wound on the outer wall of the take-up roller 4, thereby controlling the raising and lowering of the right end of the Belle tube 7. When the Belle tube 7 sinks below the groundwater level, due to water pressure, the ball check valve at its bottom opens. At this time, groundwater flows into the tube from the upper inlet of the Belle tube 7 under the action of gravity. When the Belle tube 7 is full of water sample or reaches the predetermined sampling volume, the sampling personnel pull up the Belle tube 7. As the Belle tube 7 is pulled up, the ball check valve at the bottom closes under the action of gravity, preventing the water sample from flowing out, thereby sealing the groundwater sample inside the Belle tube 7, completing the groundwater sample collection. When tube 7 is lifted, rotate knob 5 counterclockwise. Knob 5 drives take-up roller 4 to rotate around the rotating shaft on support plate 2, which in turn drives the rotating shaft to rotate. The rotation of the rotating shaft will drive the rotating column 801 to rotate through the transmission of sprocket 809 and chain 810. The inner wall of the wave groove 802 on the outer surface of the rotating column 801 is slidably connected to the outer surface of the small support block at the upper end of the support block 805. During the rotation of the rotating column 801, the small support block is guided by the wave groove 802 and slides left and right in the slide rail 803 on the left side wall of the L-shaped bracket 3 through the slider 804. At the same time, the sliding hole in the middle of the support block 805 slides along the slide rod 806. The sliding of the support block 805 drives the support rod 807 and the right end dial ring 808 to move. The dial ring 808 drives the tube to be neatly wound around the outside of the take-up roller 4 during the winding process to avoid tangling during the next use. After the collection is completed, hold the handle 10 to transport the equipment and place the Belle tube 7 in the Belle tube placement box 9 for storage.
