Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection detection sampling, and more specifically, to a sampling device for detecting samples for environmental protection. Background Art

[0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharging into a certain water body or reusing it. Sewage treatment is widely applied in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering, and is also increasingly entering the daily lives of ordinary people. When treating sewage or surveying the pollution degree of certain water sources, it is necessary to sample and analyze the water body to issue a targeted treatment plan for the sewage or water source.

[0003] Currently, when conducting environmental protection analysis sampling, water is usually sampled by scooping water from the surface of the water body to be analyzed. Due to the presence of substances with different specific gravities or water quality pollution stratification in the water body, only sampling and analyzing the surface water body or the water body at a certain depth, the analysis data does not substantially represent, and the results of the sampling analysis lack authenticity and accuracy.

[0004] In order to analyze the water quality more accurately, water quality sampling should not only sample from different water body areas but also sample and analyze from different water body layers of the water body, that is, at different depths of the water body. Only in this way can the taken water body samples be representative. However, there is currently no equipment that can efficiently sample water at different depths simultaneously.

[0005] In view of this, this application is specifically proposed. Content of the Utility Model

[0006] The technical problem to be solved by the utility model is that there is a lack of relevant equipment structures for simultaneously sampling water at different depths during current environmental protection analysis sampling. The purpose is to provide a sampling device for detecting samples for environmental protection. By setting liquid inlet adjusting pipes at different heights and respectively configuring storage cavities, it is possible to simultaneously sample from different depths of the same water body, ensure the accuracy of the sampling depth, and also adjust the distance between different sampling depths according to actual needs to meet the needs of diversified sampling.

[0007] The utility model is realized through the following technical solutions:

[0008] A sampling device for detecting samples for environmental protection, including a sampling storage tube, and the interior of the sampling storage tube is divided into multiple storage cavities from top to bottom;

[0009] An inlet liquid adjusting tube is installed on the outer side wall of the sampling storage tube, and the interior of the inlet liquid adjusting tube is of a hollow structure;

[0010] A liquid inlet hole is formed at the top of each storage cavity, and the outer end of the liquid inlet hole extends through the outer wall of the sampling storage tube and communicates with the interior of the liquid inlet regulating tube;

[0011] A plurality of liquid inlets are provided on the outer wall of the liquid inlet regulating tube from top to bottom, and the liquid inlet holes corresponding to the storage cavity are connected with the liquid inlets;

[0012] The outer wall of the liquid inlet regulating tube is covered with a rear opening and closing plate, on which a liquid inlet pair hole is provided. The opening and closing plate can be horizontally rotated along the outer circumference of the liquid inlet regulating tube until the liquid inlet pair hole is aligned with the liquid inlet port.

[0013] The utility model can realize simultaneous sampling from different depths of the same water body by setting liquid inlets at different heights and configuring storage cavities respectively, while ensuring the accuracy of the sampling depth. When the sampling device of the utility model is used, the sampling storage tube and the liquid inlet regulating tube are first placed as a whole in the water body to be sampled. When placed at a suitable depth, the opening and closing plate is rotated to align the liquid inlet hole with the liquid inlet, and the water bodies at different depths flow into the liquid inlet hole through the liquid inlet and finally enter the storage cavity. After the sampling is completed, the opening and closing plate is rotated and reset to stagger the liquid inlet hole with the liquid inlet, and then the sampling storage tube and the liquid inlet regulating tube are lifted out as a whole, that is, the sampling of water bodies at different depths is completed at one time.

[0014] In a specific embodiment, a blocking float is provided in each storage cavity, and the diameter of the blocking float is larger than the inner diameter of the liquid inlet hole. The blocking float gradually moves upward under the action of the buoyancy of the liquid until it reaches the top of the storage cavity to block the liquid inlet hole. When the water finally enters the storage cavity through the liquid inlet hole, the water level gradually rises, and the blocking float floats on the water surface and rises with the water level. When the blocking float fits with the end of the liquid inlet hole, the liquid inlet hole is blocked, which can ensure that the water in the storage cavity will not flow back out.

[0015] In a specific embodiment, the top of the storage cavity is a conical structure that is small at the top and large at the bottom, and the inner end of the liquid inlet is opened at the top of the conical structure. As the water level rises, the blocking float can move toward the liquid inlet port under the restriction of the inclined surface of the conical structure, ensuring that the blocking float can block the liquid inlet port.

[0016] In a specific embodiment, a drainage pipe connected to the storage cavity is further provided on the outer wall of the sampling storage tube, and the water sample in the storage cavity can be conveniently discharged through the drainage pipe.

[0017] In a specific embodiment, a plurality of liquid inlets corresponding to the liquid inlet hole of a storage cavity are provided as a group of liquid inlets, and each group of liquid inlets is covered with an opening and closing plate, which can move up and down along the outer wall of the liquid inlet regulating tube to realize the alignment of the liquid inlet holes and different liquid inlets.

[0018] The utility model sets a plurality of corresponding liquid inlets for each liquid inlet hole, so that the water intake depth of each storage cavity can be adjusted, and the adjustment of the water intake spacing of different depths can be realized. For example, sampling of different depths with equal spacing can be realized, and sampling of different depths with unequal spacing can be realized.

[0019] In a specific embodiment, a vertical groove parallel to the axis of the liquid inlet regulating tube is provided on the outer wall of the liquid inlet regulating tube, and an opening and closing slide rod is provided in the groove, and the opening and closing slide rod can slide horizontally in the groove; the opening and closing plate is fitted on the surface of the liquid inlet regulating tube and the two ends are respectively installed on two opening and closing slide rods, and the opening and closing plate can slide up and down along the opening and closing slide rod.

[0020] The utility model invention realizes the horizontal and up and down movement of the opening and closing plate at the same time by setting an opening and closing slide rod and a groove structure; wherein the up and down movement of the opening and closing plate is realized by a sliding connection between the opening and closing plate and the opening and closing slide rod to select liquid inlets at different heights, and the horizontal movement of the opening and closing plate is driven by the horizontal movement of the opening and closing slide rod in the groove to realize the alignment of the liquid inlet hole and the liquid inlet.

[0021] The specific operation is that, first, when placing the device into the water body, adjust the upper and lower positions of each opening and closing plate to determine the liquid inlet that needs to be aligned. Then, after placing the device into the water, push the opening and closing slide bar to move in the groove, driving all the opening and closing plates to rotate at the same time so that all the liquid inlet holes are aligned with the liquid inlet.

[0022] In a specific embodiment, the liquid inlet hole is connected to a corresponding group of liquid inlets by a multi-way hose.

[0023] In a specific embodiment, the opening and closing plate is made of transparent material, which can facilitate the position adjustment of the opening and closing plate so as to quickly select the liquid inlet that needs to be aligned; the sampling storage tube and the liquid inlet regulating tube are both made of stainless steel to ensure the overall strength and corrosion resistance of the device.

[0024] In a specific embodiment, the edges of the butt ends of the liquid inlet holes and the liquid inlet port are covered with rubber sealing rings, which can improve the sealing performance at the edges of the liquid inlet holes and the liquid inlet port.

[0025] In a specific embodiment, the upper end of the opening and closing slide bar extends out of the top of the liquid inlet regulating tube and the rotating disk, and the opening and closing slide bar is driven to move horizontally in the groove by horizontally rotating the rotating disk, and a hand-held rod is also provided at the center of the rotating disk. The utility model can facilitate the sampling operation and save labor by providing the rotating disk and the hand-held rod.

[0042] Embodiment

[0043] As Figures 1 - 4 shown, a sampling device for detecting samples for environmental protection provided by an embodiment of the present utility model includes a sampling storage tube 1, and the interior of the sampling storage tube 1 is divided into a plurality of storage cavities 2 from top to bottom;

[0044] An inlet liquid regulating pipe 3 is installed on the outer side wall of the sampling storage pipe 1, and the inside of the inlet liquid regulating pipe 3 is of a hollow structure;

[0045] An inlet liquid hole 4 is opened at the top of each storage cavity 2, and the outer end of the inlet liquid hole 4 extends through the outer side wall of the sampling storage pipe 1 and is communicated with the inside of the inlet liquid regulating pipe 3;

[0046] A plurality of inlet liquid ports 5 are opened on the outer wall of the inlet liquid regulating pipe 3 from top to bottom, and the inlet liquid hole 4 corresponding to the storage cavity 2 is communicated with the inlet liquid port 5;

[0047] The outer wall of the inlet liquid regulating pipe 3 is covered with an opening and closing plate 6, and an inlet liquid alignment hole 7 is opened on the opening and closing plate 6. The opening and closing plate 6 can horizontally rotate along the outer circumference of the inlet liquid regulating pipe 3 until the inlet liquid alignment hole 7 is aligned with the inlet liquid port 5.

[0048] By arranging inlet liquid ports at different heights and respectively configuring storage cavities, the utility model can simultaneously sample from different depths of the same water body and ensure the accuracy of the sampling depth. When the sampling device of the utility model is in use, first, the sampling storage pipe and the inlet liquid regulating pipe are integrally placed into the water body to be sampled. When placed at an appropriate depth, the opening and closing plate is rotated to align the inlet liquid alignment hole with the inlet liquid port. The water bodies at different depths flow into the inlet liquid hole through the inlet liquid port and finally enter the storage cavity. After sampling, the opening and closing plate is rotated back to its original position to stagger the inlet liquid alignment hole from the inlet liquid port, and then the sampling storage pipe and the inlet liquid regulating pipe are integrally lifted out, that is, the sampling of water bodies at different depths is completed at one time.

[0049] In a specific embodiment, a blocking floating ball 8 is arranged in each storage cavity 2. The diameter of the blocking floating ball 8 is larger than the inner end diameter of the inlet liquid hole 4. The blocking floating ball 8 gradually moves upward under the action of liquid buoyancy until the top of the storage cavity 2 blocks the inlet liquid hole 4. When the water body finally enters the storage cavity through the inlet liquid hole, the water level gradually rises. The blocking floating ball 8 floats on the water surface and rises with the water level. When the blocking floating ball 8 fits with the end of the inlet liquid hole, the inlet liquid hole is blocked, which can ensure that the water body in the storage cavity will not flow back.

[0050] In a specific embodiment, the top of the storage cavity 2 is of a conical structure with a smaller top and a larger bottom, and the inner end of the inlet liquid hole 4 is opened at the top of the conical structure. During the rising process of the water level, the blocking floating ball can move towards the port of the inlet liquid hole under the limiting action of the inclined surface of the conical structure, ensuring that the blocking floating ball can block the port of the inlet liquid hole.

[0051] In a specific embodiment, a drain pipe 9 communicated with the storage cavity 2 is further arranged on the outer wall of the sampling storage pipe 1, and the water body sample in the storage cavity can be conveniently discharged through the drain pipe.

[0052] In a specific embodiment, a plurality of liquid inlets 5 corresponding to the liquid inlet holes 4 of a storage cavity 2 are provided as a group of liquid inlets 5, and an opening and closing plate 6 is covered at each group of liquid inlets 5. The opening and closing plate 6 can move up and down along the outer wall of the liquid inlet adjusting pipe 3 to align the liquid inlet holes 7 with different liquid inlets 5.

[0053] In the present utility model, by providing a plurality of corresponding liquid inlets for each liquid inlet hole 4, the water intake depth of each storage cavity can be adjusted, so that the adjustment of the water intake spacing at different depths can be realized. For example, sampling at different depths with equal spacing can be achieved, or sampling at different depths with unequal spacing can be achieved.

[0054] In a specific embodiment, vertical grooves 10 parallel to the axis of the liquid inlet adjusting pipe 3 are formed on the outer wall of the liquid inlet adjusting pipe 3, and opening and closing sliding rods 11 are arranged in the grooves 10. The opening and closing sliding rods 11 can slide horizontally in the grooves 10. The opening and closing plate 6 is attached to the surface of the liquid inlet adjusting pipe 3 and both ends are respectively installed on two opening and closing sliding rods 11. The opening and closing plate 6 can slide up and down along the opening and closing sliding rods 11.

[0055] In the present invention of the utility model, the horizontal and vertical movements of the opening and closing plate are realized by setting the opening and closing sliding rods and the groove structure. Among them, the up and down movement of the opening and closing plate is realized by the sliding connection between the opening and closing plate and the opening and closing sliding rods to select liquid inlets at different heights, and the horizontal movement of the opening and closing plate is driven by the horizontal movement of the opening and closing sliding rods in the grooves to align the liquid inlet holes with the liquid inlets.

[0056] The specific operation is as follows. First, when the device is placed in the water body, the up and down positions of each opening and closing plate are adjusted to determine the liquid inlets that need to be aligned. Then, after the device is placed in the water, by pushing the opening and closing sliding rods to move in the grooves, all the opening and closing plates are driven to rotate simultaneously to align all the liquid inlet holes with the liquid inlets.

[0057] Among them, a positioning lock structure is provided between the opening and closing sliding rods and the opening and closing plate, and between the opening and closing sliding rods and the grooves to ensure that the opening and closing plate and the opening and closing sliding rods will not move randomly after the movement is in place.

[0058] In a specific embodiment, the liquid inlet holes 4 and a corresponding group of liquid inlets 5 are connected by a multi-way hose.

[0059] In a specific embodiment, the opening and closing plate 6 is made of a transparent material, which can facilitate the adjustment of the position of the opening and closing plate so as to quickly select the liquid inlets that need to be aligned. The sampling storage pipe 1 and the liquid inlet adjusting pipe 3 are both made of stainless steel to ensure the overall strength and corrosion resistance of the device.

[0060] In a specific embodiment, rubber sealing rings are covered at the edges of the liquid inlet pair holes 7 and the butting ends of the liquid inlet 5, which can improve the sealing performance at the edges of the liquid inlet pair holes and the liquid inlet.

[0061] In a specific embodiment, the upper end of the opening and closing slide rod 11 extends out of the top of the liquid inlet adjusting pipe 3 and is connected to the rotating disc 12. By horizontally rotating the rotating disc 12, the opening and closing slide rod 11 is driven to move horizontally in the groove. A hand-held rod 13 is further arranged at the center of the rotating disc 12. By arranging the rotating disc and the hand-held rod in the present utility model, the sampling operation can be more convenient and more labor-saving in use.

[0062] The above specific embodiment further details the purpose, technical solution and beneficial effects of the present utility model. It should be understood that the above is only the specific embodiment of the present utility model and is not used to limit the protection scope of the present utility model.
