Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water quality detection, and more specifically to a water quality detection sampling device. Background Art
[0002] Water resources are the most important natural resources of human society and the basic conditions for survival and development. The sustainable utilization of water resources is an extremely important guarantee for the sustainable development of society and economy. In recent years, with the increasing severity of water pollution, water quality detection, as a basic task in water pollution control work, is of great significance. Currently, the water quality detection sampling devices are all straight glass cups. The staff ties a nylon rope to the outside of the glass cup and makes the glass cup sink to the bottom naturally. According to the descending length of the nylon rope, the sampling depth of the glass cup is judged. However, the glass cup is a fragile item and not convenient to carry. At the same time, there is a certain flow rate underwater, which causes water to flow into the glass cup from top to bottom when the glass cup sinks to take samples. Since the water quality at different depths has certain differences, the samples in the glass cup have certain deviations, which will affect the actual water quality detection results. Content of the Utility Model
[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a water quality detection sampling device to solve the problems existing in the above background art.
[0004] The utility model provides the following technical solution: A water quality detection sampling device includes a sampling cup. A sealing cover is provided at the top of the sampling cup. An inlet valve is provided inside the sealing cover. A pressure sensor is provided at the top of the sealing cover on one side of the inlet valve. A liquid level sensor is provided at the bottom of the inner wall of the sealing cover on one side of the inlet valve. A data socket is provided at the top of the sealing cover on one side of the pressure sensor. Through the data socket, a computer sets the pressure above the pressure sensor at the required sampling depth, so that when the sampling cup reaches the actual sampling depth, the underwater pressure squeezes the pressure sensor at this time, so that the pressure sensor opens the inlet valve for sampling. The liquid level sensor monitors the liquid level in the sampling cup in real time. When the sampling requirement is met, the liquid level sensor closes the inlet valve, thereby preventing water flows at different depths from entering the sampling cup and interfering with the water sample, increasing the accuracy of the water quality detection result.
[0005] Further, a protective cover is provided at the top of the data socket. The data socket is separated from the outside through the protective cover, thereby protecting the data socket and preventing water from entering and damaging the data socket during sampling, increasing the service life and use safety of the data socket.
[0006] Furthermore, a connection block is provided at the outer top of the sampling cup. A connecting pipe is provided inside the connection block. Scale grooves are equidistantly arranged on the surface of the connecting pipe. A connection component is provided at the top of the connecting pipe. Both the connecting pipe and the connection component are 1 meter in length. The scale grooves equidistantly arranged on the surfaces of the connecting pipe and the connection component facilitate the staff to observe the depth of the sampling cup when sampling downward. The length of 1 meter for the connecting pipe and the connection component is convenient for the staff to transport, carry and assemble, increasing the comfort of use for the staff.
[0007] Furthermore, a weight component is provided at the outer bottom of the sampling cup. A weight base is provided inside the weight component. A clamping post is provided at the top of the weight base. The weight block is fixed by the clamping post, so that the weight block will not shake inside the weight component, thereby increasing the stability of the sampling cup when sampling.
[0008] Furthermore, clamping blocks are provided on both sides of the weight base. Fixing bolts are provided outside the weight component and located inside the weight base. The weight base is fixed inside the weight component through the fixing bolts, thereby limiting the weight block above the weight base inside the weight component. The clamping blocks facilitate the staff to align the weight base with the weight component one by one, thus facilitating the fixing by the fixing bolts.
[0009] Compared with the prior art, the beneficial effect of the present invention is that the computer sets the pressure above the pressure sensor at the required sampling depth through the data socket. When the sampling cup reaches the actual sampling depth, the underwater pressure then squeezes the pressure sensor, so that the pressure sensor opens the water inlet valve for sampling. The liquid level sensor monitors the liquid level in the sampling cup in real time. When the sampling requirement is met, the liquid level sensor closes the water inlet valve, thereby preventing water flows at different depths from entering the sampling cup and interfering with the water sample, increasing the accuracy of the water quality detection result.

[0015] The specific embodiments of the present utility model will be described below in conjunction with the drawings.
[0016] Embodiment 1
[0017] Referring to Figures 1-3 , for a water quality detection sampling device, first install the clamping column 15 at the middle of the top of the counterweight base 14, then install the clamping block 16 on both sides of the counterweight base 14, then install the counterweight base 14 inside the counterweight assembly 12 and fix it with the fixing bolt 13. Next, install the connecting block 2 at the top of the outer side of the sampling cup 1. Then, equally spaced scale grooves 4 are opened on the outer sides of the connecting pipe 3 and the connecting assembly 5. Then, install the water inlet valve 7 inside the sealing cover 6, then install the pressure sensor 8 outside the water inlet valve 7 at the top of the sealing cover 6. Next, install the liquid level sensor 11 outside the water inlet valve 7 at the bottom of the inner wall of the sealing cover 6. Then, install the data socket 10 on one side of the pressure sensor 8 at the top of the sealing cover 6, and install the protective cover 9 on the top of the data socket 10. Next, screw the connecting pipe 3 into the connecting block 2, then screw the connecting assembly 5 into the connecting pipe 3, and finally install the counterweight assembly 12 at the bottom of the outer side of the sampling cup 1.
[0018] Working principle of the utility model: The staff calculates the water pressure at the depth of the pressure sensor 8 according to the required sampling depth and the size of the pressure sensor 8. Then, the computer sets the sensing readings of the pressure sensor 8 and the liquid level sensor 11 through the data socket 10, selects an appropriate number of counterweight blocks, installs them outside the clamping posts 15 at the top of the counterweight base 14, then installs the counterweight base 14 inside the counterweight assembly 12, and fixes it with the fixing bolts 13. Then, an appropriate number of connecting pipes 3 and connecting components 5 are selected and installed on the connecting block 2. Next, the staff holds the connecting pipes 3 and connecting components 5 and slowly inserts the sampling cup 1 into the water. At this time, the staff judges the depth of the sampling cup 1 inserted into the water according to the readings of the scale grooves 4 on the surfaces of the connecting pipes 3 and connecting components 5. When it reaches a certain depth, the water squeezes the pressure sensor 8, so that the pressure sensor 8 opens the water inlet valve 7. Then, the water flows into the sampling cup 1 through the water inlet valve 7. When the water level in the sampling cup 1 rises to the liquid level sensor 11, the liquid level sensor 11 detects the water level in the sampling cup 1 until it reaches the set water level height, and then closes the water inlet valve 7. At this time, the staff takes out the sampling cup 1 through the connecting pipes 3 and connecting components 5, then unscrews the sealing cover 6 from the sampling cup 1, and pours the water in the sampling cup 1 into the storage bottle, which is convenient for the staff to transport and detect it.
