Description

Technical Field

[0001] This utility model relates to the field of wastewater monitoring technology, specifically a wastewater monitoring instrument that can automatically sample and save data. Background Technology

[0002] With the acceleration of urbanization and the improvement of living standards, the amount of wastewater generated by people's daily lives has increased dramatically. This wastewater often contains various chemical elements. If it is discharged directly without effective monitoring, it will not only increase the difficulty and cost of subsequent purification and treatment, but may also cause irreversible pollution to the ecological environment. Therefore, professional wastewater monitoring instruments are used for auxiliary monitoring and treatment in the wastewater discharge process.

[0003] Existing equipment often requires manual transfer to the laboratory for analysis after sampling, which not only consumes a lot of manpower and time, but also may cause sample contamination or deterioration due to factors such as bumps and temperature changes during transportation, greatly affecting the accuracy and reliability of monitoring results. In order to solve the above problems, a portable groundwater quality monitoring instrument is disclosed in the prior art (Chinese patent application number CN220251915U, application date 2023-05-31). This water quality monitoring instrument uses a shrinking mechanism to shrink the connecting cable between the probe and the water quality monitoring instrument, and directly snaps the probe onto the main body of the water quality monitoring instrument, so that the connecting cable will not be tangled or broken, and at the same time, it reduces the occupied area and is more convenient to carry.

[0004] Although the aforementioned water quality monitoring instrument is relatively portable, it is very easy for a large number of impurities to accumulate inside the storage tube after wastewater sampling, which can easily affect the monitoring results during subsequent sampling and monitoring.

[0005] Therefore, we proposed a wastewater monitoring instrument that can automatically sample and save wastewater, which can effectively solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a wastewater monitoring instrument that can automatically sample and preserve wastewater, in order to solve the problem mentioned in the background art that the wastewater monitoring instruments currently on the market are prone to having a large number of impurities inside the preservation tube after sampling, which can easily affect the monitoring results during subsequent sampling and monitoring.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a wastewater monitoring instrument capable of automatic sampling and preservation, comprising a receiving tube, wherein a groove for monitoring wastewater is opened inside the upper end of the receiving tube, and the outer side of the upper end of the receiving tube is threadedly connected to the lower inner wall of the monitoring head, and the top of the monitoring head is connected to the monitoring display via a wire; collection tubes are fixedly installed on both sides of the receiving tube, and an automatic pumping mechanism is provided on one side of the two sets of collection tubes to realize the preservation, collection and treatment of wastewater; a protective sleeve is also threadedly connected to the lower position of the receiving tube, and a rotating sleeve is rotatably mounted below the protective sleeve, and a brush is slidably mounted inside the rotating sleeve, which facilitates the cleaning of impurities by extending the brush.

[0008] As a preferred technical solution of this application, the bottom of the receiving tube is equipped with a downward-facing conical inlet nozzle, and a filter screen is also installed on the surface of the inlet nozzle to prevent large impurities from clogging the infusion line.

[0009] As a preferred technical solution of this application, the automatic pumping mechanism includes miniature electric push rods installed on the outside of the left and right collection tubes, and the output end of the miniature electric push rod is fixed at the top of the piston rod. The outside of the piston rod is slidably disposed inside the collection tube to facilitate negative pressure collection. The upper end of the miniature electric push rod is also connected to the inlet of the receiving tube through an inlet pipe, and the lower end of the miniature electric push rod is connected to a groove opened inside the upper end of the receiving tube through an outlet pipe.

[0010] As a preferred technical solution of this application, both the inlet pipe and the outlet pipe are equipped with one-way valves to enable the collected wastewater to move in one direction. A threaded sealing sleeve is also threadedly connected to the lower part of the collection pipe.

[0011] As a preferred technical solution of this application, a threaded sleeve is fixed at the middle of the inner side of the rotating sleeve, and the inner side of the threaded sleeve is threadedly connected to the outer side of the threaded rod. A brush is fixed at the bottom of the threaded rod, and the top outer side of the threaded rod is slidably disposed on the outer side of the guide square tube.

[0012] As a preferred technical solution of this application, the top position of the guide square tube is fixed on the bottom outer side of the protective sleeve, and the maximum movement dimension of the brush is greater than the depth of the groove opened on the upper inner side of the collection tube and the receiving tube.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This wastewater monitoring instrument with automatic sampling and storage uses miniature electric push rods on the outside of the left and right sampling tubes to drive the piston rod to slide inside the sampling tube, generating negative pressure. Through the inlet and outlet pipes and a one-way valve, wastewater is automatically collected and stored, avoiding manual transfer and contamination. The conical inlet nozzle at the bottom of the receiving tube, equipped with a filter screen, can intercept impurities and prevent blockage of the infusion line. The rotating sleeve below the protective sleeve drives the threaded sleeve and threaded rod to engage, allowing the brush to extend to a depth greater than the sampling tube and the receiving tube groove, effectively cleaning internal impurities. Specific details are as follows:

[0014] 1. Miniature electric actuators are installed on the outer sides of the left and right sampling tubes. Their output drives a piston rod to slide within the sampling tube, generating negative pressure. This negative pressure is transmitted through the inlet pipe to the inlet nozzle of the receiving tube, and the outlet pipe to a groove inside the upper part of the receiving tube. Combined with one-way valves in the inlet and outlet pipes, automatic wastewater collection and storage are achieved. This allows for convenient dual monitoring, combining the results from both sides to avoid errors caused by unforeseen events during monitoring. Furthermore, a downward-facing conical inlet nozzle is installed at the bottom of the receiving tube, with a filter screen on its surface. This filter screen effectively intercepts impurities in the wastewater, preventing larger impurities from entering the infusion line and preventing blockage. This ensures smooth liquid flow within the monitor and guarantees the normal operation of the monitoring function.

[0015] 2. A protective sleeve is threadedly connected to the lower part of the receiving tube. The threaded sleeve inside the rotating sleeve below the protective sleeve is threadedly connected to the threaded rod. The bottom of the threaded rod is fixed with a brush, and the outer side of the top of the threaded rod slides outside the guide square tube. When the rotating sleeve is rotated, the threaded sleeve drives the threaded rod to move up and down, causing the brush to extend. Since the maximum movement of the brush is greater than the depth of the groove opened on the inner side of the upper end of the collecting tube and the receiving tube, it can penetrate deep into the groove of the collecting tube and the receiving tube to effectively clean the impurities inside, reduce the impact of impurities on the subsequent sampling and monitoring results, and further improve the accuracy of monitoring.

[0023] 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.

[0024] Please see Figures 1-6 The present invention provides the following technical solution: a wastewater monitoring instrument that can automatically sample and save wastewater.

[0025] Example 1: For convenient automatic sampling and storage processing, please refer to the attached document. Figure 1 -Appendix Figure 3 and attached Figure 6 The system includes a receiving tube 1, with a wastewater monitoring groove inside the upper end of the receiving tube 1. The outer side of the upper end of the receiving tube 1 is threaded to the lower inner wall of the monitoring head 2. The top of the monitoring head 2 is connected to the monitoring display 3 via a wire. Collection tubes 4 are fixedly installed on both the left and right sides of the receiving tube 1. (See attached diagram.) Figure 6 An automatic pumping mechanism is installed on one side of each of the two sets of collection tubes 4 to achieve wastewater collection and treatment; a downward-facing conical inlet is installed at the bottom of the receiving tube 1, and a filter screen is also installed on the surface of the inlet to prevent impurities of different sizes from clogging the infusion line; see attached figure. Figure 1 and attached Figure 2 The automatic pumping mechanism includes miniature electric push rods 5 installed on the outside of the left and right collection pipes 4. The output end of the miniature electric push rod 5 is fixed to the top of the piston rod. The outside of the piston rod is slidably disposed inside the collection pipe 4 to facilitate negative pressure collection. The upper end of the miniature electric push rod 5 is also connected to the inlet of the receiving pipe 1 through the inlet pipe 7, and the lower end of the miniature electric push rod 5 is connected to the groove opened inside the upper end of the receiving pipe 1 through the outlet pipe 8. Both the inlet pipe 7 and the outlet pipe 8 are equipped with one-way valves to realize the one-way movement of the collected wastewater. A threaded sealing sleeve 6 is also threadedly connected to the lower part of the collection pipe 4.

[0026] Firstly, the downward-facing conical inlet nozzle at the bottom of the receiving tube 1, combined with the surface filter screen, intercepts larger impurities as wastewater enters from the bottom, preventing blockage of the internal infusion lines. When it moves to the designated water area, the piston rod is driven by the miniature electric push rod 5 on the outside of the left and right collection tubes 4 to slide up and down inside the collection tube 4. When the piston rod moves upward, a negative pressure is formed inside the collection tube 4, and wastewater is drawn in through the inlet nozzle via the inlet pipe 7. When the piston rod moves downward, the wastewater is forced into the monitoring tank at the upper end of the receiving tube 1 through the outlet pipe 8. The one-way valves in the inlet pipe 7 and outlet pipe 8 ensure unidirectional flow of wastewater, preventing backflow and contamination, achieving automatic sampling and delivery of wastewater to the monitoring tank. The monitoring head 2 is installed at the upper end of the receiving tube 1 and is connected to the monitoring display 3 via wires to monitor the wastewater in the monitoring tank in real time, and the data is displayed synchronously on the monitoring display 3.

[0027] Example 2: To avoid the potential for a large amount of impurities to accumulate inside the storage tube after wastewater sampling, which could affect monitoring results during subsequent sampling and monitoring, please refer to the attached document. Figure 1 -Appendix Figure 5 A protective sleeve 9 is threadedly connected to the lower part of the receiving tube 1. A rotating sleeve 10 is rotatably mounted below the protective sleeve 9. A brush 11 is slidably mounted inside the rotating sleeve 10. The extension of the brush 11 facilitates the cleaning of impurities. (See attached diagram) Figure 4 A threaded sleeve 13 is fixed to the inner middle of the rotating sleeve 10, and the inner side of the threaded sleeve 13 is threadedly connected to the outer side of the threaded rod 12. A brush 11 is fixed to the bottom of the threaded rod 12, and the top outer side of the threaded rod 12 is slidably disposed on the outer side of the guide square tube 14; see attached figure. Figure 3 The top of the guide square tube 14 is fixed to the bottom outer side of the protective sleeve 9, and the maximum movement dimension of the brush 11 is greater than the depth of the groove opened on the upper inner side of the collection tube 4 and the receiving tube 1.

[0028] A threaded sleeve 13 is fixed inside the rotating sleeve 10 below the protective sleeve 9. The threaded sleeve 13 is threadedly connected to the threaded rod 12. When the rotating sleeve 10 is rotated, the threaded sleeve 13 drives the threaded rod 12 to slide up and down along the guide square tube 14, so that the brush 11 at the bottom extends or retracts. The maximum movement dimension of the brush 11 is greater than the depth of the monitoring groove of the collection tube 4 and the receiving tube 1, ensuring that it can penetrate deep into the interior for cleaning. When cleaning is required, the rotating sleeve 10 is rotated to extend the brush 11. By manually rotating the rotating sleeve 10 and the brush 11 rotating synchronously, impurities on the inner wall of the collection tube 4, the monitoring groove of the receiving tube 1, and the vicinity of the liquid inlet are wiped and removed to avoid impurities remaining and affecting the monitoring results.
