Description

Technical Field

[0001] This application relates to the field of wastewater collection devices, and more specifically, to a wastewater collection device for environmental monitoring. Background Technology

[0002] The main purpose of wastewater sampling and testing is to assess the degree of wastewater pollution, understand water quality, promptly identify and address wastewater problems, provide crucial data support for wastewater treatment, and ensure that treated wastewater discharge meets environmental standards, protecting the environment and human health. A water quality sampler, disclosed in patent CN222105128U, avoids dragging the sample after collection, preventing large amounts of near-shore sediment and dirt from entering the sampling cylinder. This not only improves the accuracy of water quality testing but also facilitates the extraction of samples from the sampling cylinder. When sampling, there is no need to filter impurities again, thereby improving the efficiency of water quality testing. However, the inventor believes that the above-mentioned related technologies still have the following defects: the water quality sampler in the literature cannot be accurately controlled and monitored in real time, that is, it cannot achieve the required depth of water quality sampling. Moreover, the maximum water depth varies in different water areas. When the water quality sampler is lowered to a greater depth, it is easy for the water quality sampler to touch the bottom of the silt, resulting in the presence of silt and impurities in the sampled water, which affects the water quality testing. In view of this, we propose a wastewater collection device for environmental testing. Utility Model Content

[0003] 1. Technical problems to be solved

[0004] The purpose of this application is to provide a wastewater sampling device for environmental monitoring, which solves the technical problems in the background art mentioned above. The device consists of a human-computer interaction display screen, a water sampler, and a cable. The water sampler can be lowered into the water body using the cable, and the lowering depth can be accurately monitored and processed in real time. It is convenient to lower the sampler to the required depth for sampling. The device pumps water into a quantitative sampling bottle, causing the gas inside the bottle to be expelled and rise to the water surface in the form of bubbles. By observing the disappearance of the bubbles on the water surface, it can be accurately determined that the quantitative sampling bottle is full of water. Furthermore, the use of four foldable and retractable support frames avoids the curved perforated plate touching the bottom of the silt, which would cause the silt to be sampled. The device is convenient to use and operate, and has good portability.

[0005] 2. Technical Solution

[0006] This application provides a wastewater collection device for environmental monitoring, comprising: a human-computer interaction display screen and a water quality collector, wherein a cable connects the human-computer interaction display screen and the water quality collector.

[0007] The water quality collector includes a protective shell, which includes an end cap. The end cap is threadedly connected to a device shell, which is threadedly connected to a sampling mounting shell. A depth measuring mechanism and a sampling mechanism are installed inside the device shell. The sampling mounting shell has an installation cavity and a water intake cavity. A quantitative sampling bottle is detachably installed in the installation cavity. Two arc-shaped perforated plates are fixed to the water intake cavity by bolt threads. The sampling mechanism includes a sampling water pump, which is fixedly installed inside the device shell. The sampling water pump is fixedly connected to an outlet pipe and a suction pipe. The outlet pipe extends into the installation cavity and is sealed and plugged into the quantitative sampling bottle. The suction pipe passes through the device shell and the installation cavity in sequence and extends into the water intake cavity. A bottom-touching support mechanism is installed at the bottom of the sampling mounting shell.

[0008] By adopting the above technical solution, the water quality sampling device consists of a human-machine interface display screen, a water quality sampler, and a cable. The water quality sampler is lowered into the water body using the cable. The protective shell of the water quality sampler is composed of an end cap, an equipment shell, and a sampling mounting shell connected by threads. A depth measuring mechanism and a sampling water pump are installed in the equipment shell. The depth measuring mechanism can detect the sampling depth of the water quality sampler using the pressure at different water depths. A quantitative sampling bottle is installed in the mounting cavity of the sampling mounting shell, and the upper port of the quantitative sampling bottle is connected to the water outlet pipe. The sampling pump is connected to a suction pipe that extends into the water intake chamber. The sampling pump then draws water samples from the chamber through the suction pipe. The water is filtered through an arc-shaped perforated plate to prevent impurities from being sucked into the pump and damaged. The water is then pumped into a quantitative sampling bottle. Gas inside the bottle is expelled and rises to the water surface as bubbles. Once the bottle is completely filled with water at the required depth, bubble production stops. By observing the disappearance of bubbles on the water surface, the purpose of quantitative sampling can be accurately determined. The system is convenient to use and operate, and highly portable.

[0009] Optionally, both the mounting cavity and the water intake cavity are through-slot structures with an elliptical cross-section.

[0010] By adopting the above technical solution, both the installation cavity and the water intake cavity are through-groove structures. The quantitative sampling bottle can be easily disassembled and processed from the installation cavity. The water intake cavity is connected to the water environment by setting the through-groove structure, and external water debris is blocked by the arc-shaped hollow plate.

[0011] Optionally, the sampling mounting shell is fixedly provided with two first springs at the bottom of the mounting cavity, and a top plate is fixedly provided at the upper end of the first spring. The quantitative sampling bottle is provided with a water inlet at the upper end, the bottom end of the quantitative sampling bottle squeezes the top plate, and the water outlet is sealed and inserted into the water inlet.

[0012] By adopting the above technical solution, when installing the quantitative sampling bottle, the bottom presses down on the top plate, causing the first spring to deform elastically. When the quantitative sampling bottle is released, the first spring returns to its original position, and the top plate holds the quantitative sampling bottle, so that the water outlet pipe is installed in a sealed plug-in manner inside the water inlet.

[0013] Optionally, a one-way exhaust valve is fixedly fitted onto the upper end of the quantitative sampling bottle, and an exhaust pipe is detachably fitted onto the one-way exhaust valve.

[0014] By adopting the above technical solution, when the sampling water pump pumps water into the quantitative sampling bottle, the air in the quantitative sampling bottle is compressed and discharged from the exhaust pipe at the one-way exhaust valve, forming bubbles and rising to the surface of the water area.

[0015] Optionally, the depth measuring mechanism includes a guide tube, which is fixedly sleeved on the equipment housing. A fixed resistance measuring block is fixedly installed inside the equipment housing. A convex cavity is provided inside the guide tube. A T-shaped valve stem is installed in a sealed manner through the convex cavity. The T-shaped valve stem movably passes through the fixed resistance measuring block and is fixedly connected to a movable resistance measuring block. A second spring is sleeved and installed between the fixed resistance measuring block and the movable resistance measuring block. A signal line is electrically connected between the fixed resistance measuring block and the movable resistance measuring block.

[0016] By adopting the above technical solution, when the protective shell submerges to a certain water depth, it is affected by the water pressure. The T-shaped valve stem moves along the convex cavity of the guide tube, causing the distance between the fixed resistance measuring block and the movable resistance measuring block to change. The human-machine interface display screen has a built-in resistance change detector and a water pump controller, which can monitor the resistance change in real time using signal lines and calculate the submersion depth of the protective shell using algorithms. When the required depth is reached, the water pump controller is used to start the sampling water pump.

[0017] Optionally, the bottom support mechanism includes four support frames, each support frame including legs and struts. The upper end of each leg is rotatably connected to the sampling mounting shell via a damping shaft. A hinge is slidably mounted on each leg. The hinge is rotatably connected to one end of the strut via a shaft, and the other end of the strut is rotatably connected to the sampling mounting shell via a shaft.

[0018] By adopting the above technical solution, when the diving depth of the protective shell is too deep, in order to avoid the arc-shaped hollow plate of the sampling installation shell touching the bottom of the silt and causing the silt to be sampled, the four support frames can be opened before the protective shell is lowered, and the four legs can be used to touch the bottom of the silt for treatment.

[0019] Optionally, the sampling mounting shell has a strip-shaped storage groove at each support frame, the support leg has a guide groove, and the hinge seat is slidably disposed in the guide groove.

[0020] By adopting the above technical solution, the outriggers are rotated and opened, allowing the hinge to slide along the guide groove and drive the support rod to rotate. Thus, during carrying, the outriggers and support rods can be folded and stored in the corresponding strip storage slots for easy carrying and handling.

[0021] 3. Beneficial effects

[0022] One or more technical solutions provided in this application have at least the following technical effects or advantages: The water quality sampling device consists of a human-computer interaction display screen, a water quality collector, and a cable. The water quality collector can be lowered into the water body using the cable. The lowering depth can be accurately monitored and processed in real time, making it convenient to lower to the required depth for sampling. The water quality is pumped into the quantitative sampling bottle, causing the gas in the quantitative sampling bottle to be expelled and rise to the water surface in the form of bubbles. By observing the disappearance of the bubbles on the water surface, it can be accurately determined that the quantitative sampling bottle is full of water quality. In addition, the use of four foldable and retractable support frames avoids the curved hollow plate touching the bottom silt, which would cause the silt to be sampled. It is convenient to use and operate, and has good portability. Attached Figure Description

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] Reference Figures 1 to 5 This application provides a wastewater collection device for environmental monitoring, comprising: a human-computer interaction display screen 10 and a water quality collector 20, wherein a cable 30 is connected between the human-computer interaction display screen 10 and the water quality collector 20.

[0034] The water quality collector 20 includes a protective shell 1, which includes an end cap 11. The end cap 11 is threadedly connected to a device shell 12, which is threadedly connected to a sampling installation shell 13. A depth measuring mechanism 2 and a sampling mechanism 5 are installed inside the device shell 12. The sampling installation shell 13 has an installation cavity 131 and a water intake cavity 132. A quantitative sampling bottle 3 is detachably installed inside the installation cavity 131. Two arc-shaped perforated plates 14 are fixed to the water intake cavity 132 by bolt threads. The sampling mechanism 5 includes a sampling water pump 51. 1. Fixedly installed inside the equipment housing 12, the sampling water pump 51 is fixedly connected to the outlet pipe 52 and the suction pipe 53. The outlet pipe 52 extends into the mounting cavity 131 and is connected to the quantitative sampling bottle 3 in a sealed plug-in manner. The suction pipe 53 passes through the equipment housing 12 and the mounting cavity 131 in sequence and extends into the water sampling cavity 132. A bottom-touching support mechanism 4 is installed at the bottom of the sampling mounting housing 13. The water quality sampling device consists of a human-machine interactive display screen 10, a water quality collector 20, and a cable 30. The water quality collector 20 is lowered into the water body using the cable 30. Inside, the protective shell 1 of the water quality sampler 20 is composed of an end cap 11, an equipment shell 12, and a sampling mounting shell 13 connected by threads. A depth measuring mechanism 2 and a sampling water pump 51 are installed at the equipment shell 12. The depth measuring mechanism 2 can detect the sampling depth of the water quality sampler 20 using the pressure at different water depths. A quantitative sampling bottle 3 is installed in the mounting cavity 131 of the sampling mounting shell 13, with its upper end connected to the water outlet pipe 52. The suction pipe 53 of the sampling water pump 51 extends into the water sampling cavity 132. The sampling pump 51 takes water samples from the water intake chamber 132 through the suction pipe 53. The water is filtered by the arc-shaped perforated plate 14 to prevent the sampling pump 51 from being damaged by sucking in impurities. The water is then pumped into the quantitative sampling bottle 3. The gas in the quantitative sampling bottle 3 is expelled and rises to the water surface in the form of bubbles. When the quantitative sampling bottle 3 is completely filled with water of the required depth, the bubbles stop being generated. By observing the disappearance of the bubbles on the water surface, the quantitative sampling purpose of the quantitative sampling bottle 3 can be accurately determined. It is convenient to use and operate, and has good portability.

[0035] Reference Figure 1 and Figure 2 Both the mounting cavity 131 and the water intake cavity 132 are through-slot structures with an elliptical cross-section. The quantitative sampling bottle 3 can be easily disassembled and processed from the mounting cavity 131. The water intake cavity 132 is connected to the water environment by the through-slot structure, and external water debris is blocked by the arc-shaped hollow plate 14.

[0036] Reference Figure 1 and Figure 2Two first springs 16 are fixedly installed on the bottom surface of the sampling installation shell 13 inside the installation cavity 131. A top plate 15 is fixedly installed on the upper end of the first springs 16. A water inlet 32 ​​is provided on the upper end of the quantitative sampling bottle 3. The bottom end of the quantitative sampling bottle 3 presses against the top plate 15, and the water outlet pipe 52 is sealed and inserted into the water inlet 32. When the quantitative sampling bottle 3 is installed, the bottom presses down on the top plate 15, causing the first springs 16 to elastically deform. When the quantitative sampling bottle 3 is released, the first springs 16 return to their original position and support the quantitative sampling bottle 3 through the top plate 15, so that the water outlet pipe 52 is sealed and inserted into the water inlet 32.

[0037] Reference Figure 1 and Figure 3 A one-way exhaust valve 31 is fixedly connected to the upper end of the quantitative sampling bottle 3. An exhaust pipe 311 is detachably installed on the one-way exhaust valve 31. When the sampling water pump 51 pumps water into the quantitative sampling bottle 3, the air in the quantitative sampling bottle 3 is squeezed and discharged from the exhaust pipe 311 at the one-way exhaust valve 31, forming bubbles and rising to the surface of the water area.

[0038] Reference Figure 3 and Figure 4 The depth measuring mechanism 2 includes a guide tube 21, which is fixedly sleeved on the equipment housing 12. A fixed resistance measuring block 23 is fixedly installed inside the equipment housing 12. A convex cavity is provided inside the guide tube 21, and a T-shaped valve stem 22 is installed in a sealed manner through the convex cavity. The T-shaped valve stem 22 movably passes through the fixed resistance measuring block 23 and is fixedly connected to a movable resistance measuring block 24. A second spring 25 is sleeved and installed between the fixed resistance measuring block 23 and the movable resistance measuring block 24. The fixed resistance measuring block 23 and the movable resistance measuring block 24... Signal lines 26 are electrically connected between blocks 24. When the protective shell 1 is submerged to a certain water depth, it is affected by water pressure. The T-shaped valve stem 22 moves along the convex cavity of the guide tube 21, causing the distance between the fixed resistance measuring block 23 and the movable resistance measuring block 24 to change. The human-machine interaction display screen 10 has a built-in resistance change detector and a water pump controller, which can monitor the resistance change in real time using signal lines 26 and calculate the submersion depth of the protective shell 1 using an algorithm. When the required depth is reached, the water pump controller is used to make the sampling water pump 51 work.

[0039] Reference Figure 3 and Figure 5The bottom support mechanism 4 includes four support frames, each including legs 41 and struts 43. The upper end of the legs 41 is rotatably connected to the sampling installation shell 13 via a damping shaft. A hinge seat 42 is slidably mounted on the legs 41. The hinge seat 42 is rotatably connected to one end of the struts 43 via a shaft, and the other end of the struts 43 is rotatably connected to the sampling installation shell 13 via a shaft. When the diving depth of the protective shell 1 is too deep, in order to avoid the arc-shaped perforated plate 14 of the sampling installation shell 13 touching the bottom mud and causing the mud to be sampled, the four support frames are opened before the protective shell 1 is lowered, and the four legs 41 can be used to touch the bottom mud for treatment.

[0040] Reference Figure 1 and Figure 5 Each sampling mounting shell 13 has a strip-shaped storage slot at each support frame. The support leg 41 has a guide groove 411. The hinge 42 is slidably disposed in the guide groove 411. Rotating the support leg 41 opens the support leg, allowing the hinge 42 to slide along the guide groove 411 and drive the support rod 43 to rotate. Thus, during carrying, the support leg 41 and the support rod 43 can be folded and stored in the corresponding strip-shaped storage slot for easy carrying and handling.

[0041] Working principle: This water sampling device consists of a human-machine interface display screen 10, a water sampler 20, and a cable 30. In use, the bottom of the quantitative sampling bottle 3 is pressed down against the top plate 15, causing the first spring 16 to deform elastically. When the quantitative sampling bottle 3 is released, the first spring 16 returns to its original position, and the top plate 15 holds the quantitative sampling bottle 3, allowing the outlet pipe 52 to be installed in a sealed manner inside the inlet 32. Then, the four support frames are opened, and the water sampler 20 is lowered into the water body using the cable 30. As the lowering depth increases, the water pressure increases, causing the T-shaped valve stem 22 to move along the convex cavity of the guide tube 21, changing the distance between the fixed resistance block 23 and the movable resistance block 24. The built-in power supply in the human-machine interface display screen 10... The resistance change detector monitors and calculates the water depth in real time. When the water quality collector 20 reaches the required depth, the sampling water pump 51 is started by operating the human-machine interface display screen 10 and the water pump controller. The water quality filtered by the arc-shaped hollow plate 14 is drawn from the water collection chamber 132 through the suction pipe 53 and pumped into the quantitative sampling bottle 3 through the outlet pipe 52. The air in the quantitative sampling bottle 3 is compressed and discharged from the exhaust pipe 311 at the one-way exhaust valve 31, forming bubbles that rise to the water surface. When the quantitative sampling bottle 3 is completely filled with water quality at the required depth, the bubble production stops. By observing the disappearance of bubbles on the water surface, the quantitative sampling purpose of the quantitative sampling bottle 3 can be accurately determined. It is convenient to use and operate and has good portability.
