Description

Technical Field

[0001] The utility model relates to the technical field of water sample collection, in particular to a self-service water sampling terminal. Background Art

[0002] Water sampling refers to the sampling of water resources in an area. Traditionally, it is done manually. However, since manual sampling requires operators to go to sampling points repeatedly, automatic water sampling terminals have emerged. The automatic water sampling terminals control the water pump to start at a fixed time through the circuit board, and then perform sampling, which can effectively reduce the labor intensity of the staff.

[0003] In the patent application with the publication number CN 212031025 U, an intelligent water sampling instrument is disclosed. The device mainly includes two parts: a control system and a water sampling instrument device. The control system includes a main control module 1, a peristaltic pump 2 is arranged on the right side of the main control module 1, a normally open solenoid valve 3 and a normally closed solenoid valve 4 are arranged in front of the peristaltic pump 2, a winch 5 is arranged on the right side of the normally closed solenoid valve 4, a proximity switch 6 and a relay group 7 are arranged on the right side of the winch 5 in sequence, and a servo motor 8 is arranged behind the relay group 7; the water sampling instrument device includes a synchronous wheel 9 and a synchronous belt 10, a guide seat 11 is arranged on the left side of the synchronous wheel 9, a guide rod 12 is arranged on the left side of the guide seat 11, a hydroelectric composite cable 13 is connected to the left side of the guide seat 11, a water sampling port 14 is connected to the hydroelectric composite cable 13 at a position away from the guide seat 11, and a pressure sensor 15 is connected to the other end of the hydroelectric composite cable 13. The entire device is assembled into a whole by various parts, which can enable the intelligent water sampling instrument to accurately control the water depth of the water sampling terminal and complete the water sampling task.

[0004] However, there are still some shortcomings. Since the water pump draws water at regular intervals, and water is usually drawn at intervals, water left over from the last water drawing will remain in the water pipe. This water is also wastewater. Therefore, each time water is drawn, the collected water will be affected by the wastewater left over from the last water drawing, affecting the quality of each water drawing, and thus affecting subsequent testing.

[0005] Therefore, we proposed a self-service water collection terminal. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a self-service water collection terminal, which solves the problems raised in the above-mentioned background technology.

[0007] To achieve the above objectives, the utility model is implemented through the following technical solutions: a self-service water collection terminal, comprising an integrated cabinet, the inner cavity of the integrated cabinet is provided with a placement mechanism, the integrated cabinet is provided with a water collection mechanism, and the inner cavity of the integrated cabinet is installed with a main control board;

[0008] The water sampling mechanism includes a water storage tank, a downpipe, a water distribution pipe, a wastewater pipe and a water sampling pipe.

The downpipe is fixedly connected to a plurality of water distribution pipes. One side of the water distribution pipe is fixedly connected to a plurality of water sampling pipes. The bottom end of the downpipe is fixedly connected to a wastewater pipe. The wastewater pipe is connected to the downpipe and the water distribution pipe. A wastewater pipe solenoid valve is installed on the wastewater pipe, and a sampling tube solenoid valve is installed on the water sampling pipe.

[0010] Preferably, a grid plate is fixedly connected to one side of the integrated cabinet, a sampling bottle is placed on the grid plate, and the sampling bottle is connected to the water sampling pipe.

[0011] Preferably, a water pump is fixedly installed on one side of the water storage tank, one end of the water pump extends to the inner cavity of the water storage tank, the other end of the water pump is connected to a plastic water inlet pipe, and one end of the plastic water inlet pipe is sleeved with a large particle isolation mesh cover.

[0014] Preferably, universal wheels are installed at the bottom of the integrated cabinet for moving the integrated cabinet.

[0015] Compared with the prior art, the utility model has at least one of the following beneficial effects:

[0016] Since the installation position of the existing self-service water sampling terminal is a certain distance from the water source, when the water pump starts to pump water, there is a large amount of water collected last time in the pipeline. Each time sampling is performed, the residual wastewater will directly affect the sampling accuracy. The present application moves the device position, shortens the length of the water pumping pipe, and adds a wastewater pipe and a wastewater pipe solenoid valve. When pumping water, the wastewater pipe solenoid valve is first opened to discharge the wastewater collected last time remaining in the water storage tank, the sewer pipe and the inner cavity of the water distribution pipe from the wastewater pipe, and then the corresponding sampling pipe solenoid valve is opened to collect the water to be collected into the inner cavity of the sampling bottle connected to the corresponding water sampling pipe. Before each water collection, the wastewater pipe solenoid valve needs to be opened to discharge the wastewater in the pipeline first, which can effectively solve the problem of the wastewater collected last time remaining in the pipeline and ensure the authenticity and effectiveness of the collection. The device also has a built-in solar charging system, which uses the cooperation of solar panels and batteries to ensure that the solar power supply system can be used to power the equipment when power is unavailable in the wild.

[0025] Wherein: a grid plate 10 is fixedly connected to one side of the integrated cabinet 1 , a sampling bottle 11 is placed on the grid plate 10 , and the sampling bottle 11 is connected to a water sampling pipe 13 .

[0026] The grid plate 10 is used to place the sampling bottle 11 , and a water-blocking plate for blocking the wastewater pipe 12 is provided on the grid plate 10 to prevent the wastewater discharged from the wastewater pipe 12 from contacting the sampling bottle 11 .

[0027] Wherein: a water pump 7 is fixedly installed on one side of the water storage tank 15, one end of the water pump 7 extends to the inner cavity of the water storage tank 15, the other end of the water pump 7 is connected to a plastic water inlet pipe 5, and one end of the plastic water inlet pipe 5 is sleeved with a large particle isolation mesh cover 4.

[0028] Water can be pumped through the water pump 7 and pumped into the water tank through the plastic water inlet pipe 5 for collection, while the use of the large particle isolation mesh cover 4 can avoid the pumping of large particles of solids.
