Description

Technical Field

[0001] This application relates to the field of water quality monitoring equipment technology, and in particular to a multi-parameter water quality detection probe for water conservancy projects. Background Technology

[0002] The multi-parameter water quality detection probe integrates multiple sensors, such as those measuring pH, dissolved oxygen, turbidity, conductivity, and temperature, enabling it to simultaneously and in real-time acquire various key water quality indicators. This advanced equipment helps water conservancy project managers quickly and accurately assess the overall condition and changing trends of water bodies, providing more reliable data support for water resource protection and scientific management.

[0003] When replacing a measurement point with a new one after completing a test of a certain water area, the cleaning of the probe is crucial. Currently, the two most common methods after cleaning the probe are: 1. Natural air drying, which is time-consuming and affects efficiency; 2. Wiping with a cleaning cloth, which is insufficient to completely remove residual water stains from the gaps in the integrated structure. If these residual water stains are not effectively removed, they may contaminate new samples or interfere with the sensor in subsequent tests, thus affecting the accuracy of the comprehensive water quality data provided by the multi-parameter probe.

[0025] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Please see Figures 1-4 This application provides a hydraulic gate opening calibration device for quickly and thoroughly removing residual water stains from multi-parameter water quality probes.

[0027] In this embodiment, refer to Figure 1 , Figure 2 and Figure 4The multi-parameter water quality detection probe used in this water conservancy project includes: an integrated probe assembly 3 for detecting water quality and a cleaning assembly 4 for cleaning water stains; the cleaning assembly 4 may include: a mounting shell 41, a blower nozzle 42 and a blower 43, wherein the mounting shell 41 is annular and has an axially penetrating central through hole, and the outer peripheral surface of the mounting shell 41 is an annular continuous curved surface; the blower nozzles 42 are distributed in a circumferential array along the inner peripheral wall of the mounting shell 41 toward the central through hole, and the air inlet end of each blower nozzle 42 is connected to the interior of the mounting shell 41, and the air outlet end is a pressurized jet port; the air outlet of the blower 43 is connected to the annular outer peripheral surface of the mounting shell 41, and is used to deliver airflow into the inner cavity of the mounting shell 41.

[0028] Specifically, when the integrated probe assembly 3 is in the central through hole of the mounting housing 41, the airflow is delivered to the inner cavity of the mounting housing 41 by the blower 43. After the airflow reaches a certain volume in the inner cavity of the mounting housing 41, it will be blown out to the integrated probe assembly 3 through the pressurized jet nozzle. The high-pressure airflow can dry the water stains remaining on the integrated probe assembly 3, thereby improving the efficiency of further use of the integrated probe assembly 3.

[0029] See Figure 4 The blowing assembly 4 may also include a rotating component 44, which includes a sliding plate 444, an annular rack 441, a rotating gear 442, and a rotating motor 443. The annular rack 441 is mounted on the outer periphery of the mounting housing 41 near the axial direction and is arranged circumferentially along the outer periphery of the mounting housing 41. The sliding plate 444 is slidably connected to the inner circumferential surface of the mounting housing 41 along the circumferential direction, and the blowing nozzle 42 is arranged in an array along the circumferential direction of the sliding plate 444. The rotating gear 442 meshes with the annular rack 441. A connecting plate is provided between the rotating gear 442 and the sliding plate 444. One end of the connecting plate is fixedly connected to the sliding plate 444, and the other end is rotatably connected to the rotating gear 442. The rotating motor 443 is mounted on the connecting plate, and its output end is coaxially fixedly connected to the rotating gear 442.

[0030] Specifically, after the high-pressure airflow is blown out from the nozzle 42, the rotating motor 443 drives the rotating gear 442 to rotate along the ring rack 441, which in turn drives the nozzle 42 to move circumferentially along the sliding plate 444. During the movement of the nozzle 42, the direction of the high-pressure airflow can be changed, so that the area blown by the high-pressure airflow towards the integrated probe assembly 3 is larger, and it is also easier to move the residual water stains, further improving the drying speed and accelerating the reuse rate of the integrated probe assembly 3.

[0031] Reference Figure 1The detection probe also includes a protective shell 2 and a floating plate 1. The protective shell 2 is a cylindrical body with an internal cavity. A conical plate is installed at one end of the protective shell 2. The tip of the conical plate is axially away from the cylindrical body. An avoidance opening 211 is opened at the tip of the conical plate. A water-blocking plate 21 is hinged to the side of the avoidance opening 211 away from the cavity. A torsion spring 212 is installed at the hinge of the water-blocking plate 21 and the conical plate. A blower 43 is installed on the floating plate 1, and the top of the blower 43 protrudes from the surface of the floating plate 1.

[0032] The cylindrical body is open at one end away from the conical plate. The float plate is fixedly installed at one end of the open opening of the protective shell 2. The integrated probe assembly 3 is located in the accommodating cavity and connected to the float plate. The cleaning assembly 4 is also installed in the accommodating cavity of the protective shell 2, and the integrated probe assembly 3 is located in the through hole in the middle of the mounting shell 41.

[0033] Specifically, the floating plate 1 can float on the water surface, and the blower 43 installed in the floating plate 1 protrudes from the surface of the floating plate 1 and is used to blow air into the mounting shell 41; the setting of the protective shell 2 and the water baffle 21 can effectively prevent debris in the water from entering the receiving cavity, and at the same time prevent floating debris in the water from colliding with the integrated probe assembly 3.

[0034] Reference Figure 2 The cleaning assembly 4 also includes a lifting component 45, which includes a threaded rod 452, a threaded sleeve 453, and a lifting motor 451. The threaded rod 452 is axially arranged inside the protective shell 2 and connected to the protective shell 2 by two connecting pieces. The two connecting pieces are spaced apart axially along the protective shell 2, with one end fixedly connected to the inner wall of the protective shell 2 and the other end rotatably connected to the threaded rod 452. The threaded sleeve 453 is sleeved on the threaded rod 452 and moves axially along the threaded rod 452 through the internal thread. The outer wall of the threaded sleeve 453 is fixedly connected to the mounting shell 41. The lifting motor 451 is fixedly mounted on the connecting plate near the floating plate 1, and the drive end of the lifting motor 451 is fixedly connected to the end of the threaded rod 452.

[0035] Specifically, the lifting motor 451 can drive the threaded rod 452 to rotate, and at the same time drive the mounting shell 41 to reciprocate along the protective shell 2 axially through the threaded sleeve 453, thereby achieving a larger range of cleaning and drying of the integrated probe assembly 3.

[0036] Reference Figure 2The air blowing assembly 4 also includes an extension tube 46, which includes an output tube 461, a corrugated tube 462, and an inlet tube 463. One end of the output tube 461 is connected to the output end of the hair dryer 43, which is fixedly installed outside the protective shell 2, and the other end extends into the receiving cavity. One end of the inlet tube 463 is connected to the outer periphery of the mounting shell 41. Both ends of the corrugated tube 462 are connected to one end of the output tube 461 and one end of the inlet tube 463, respectively. Through the connection of the output tube 461, the corrugated tube 462, and the inlet tube 463, the airflow from the hair dryer 43 is delivered to the mounting shell 41.

[0037] In an exemplary embodiment, the bellows 462 is made of a flexible material, and the wall of the bellows 462 can extend and contract along the axial direction of the threaded pipe.

[0038] Specifically, when the mounting shell 41 is driven by the threaded sleeve 453 to reciprocate along the threaded tube, the bellows 462 can extend and retract accordingly, without affecting the normal flow of air blown out by the blower 43 to the inner cavity of the mounting shell 41, thus further improving the blowing range of the airflow.

[0039] Reference Figure 2 and Figure 3 The integrated probe assembly 3 includes: a push cylinder 33, a mounting base 32, and a sensor 31. The push cylinder 33 is axially mounted on the floating block along the accommodating cavity. The fixed end of the push cylinder 33 is fixedly connected to the floating block. The mounting base 32 is mounted on the driving end of the push cylinder 33. The push cylinder 33 drives the mounting base 32 to move axially along the accommodating cavity. There are multiple sensors 31, including dissolved oxygen sensor 31, conductivity sensor 31, pH sensor 31, turbidity sensor 31, and temperature sensor 31. Multiple different sensors 31 are arranged in a concentric array along the end face of the mounting base 32 away from the push cylinder 33.

[0040] Specifically, the push cylinder 33 can push downwards through the drive end, moving the sensor 31 downwards through the clearance port 211. The sensor 31 extends into the water through the push-open water baffle 21 to perform multi-parameter detection of water quality. The concentric array distribution of various sensors 31 can maximize the installation rate of the mounting base 32.

[0041] Reference Figure 1 A water pump 22 is installed on the side of the baffle plate 21 away from the accommodating cavity.

[0042] Specifically, when the integrated probe assembly 3 pushes open the water baffle 21 and extends into the water to detect various data in the water quality, water will flow into the receiving cavity through the avoidance port 211. After the detection is completed, the integrated probe assembly 3 retracts into the receiving cavity, and the torsion spring 212 drives the water baffle 21 to block the avoidance port 211 again to prevent water from continuing to enter the receiving cavity. At this time, the water pump 22 is turned on to drain all the water in the receiving cavity, ensuring that the integrated detection probe is in a dry environment. Then, the cleaning component blows all the water stains remaining on the integrated probe assembly 3 onto the side wall of the receiving cavity. The water flows along the side wall to the conical plate, and then converges at the avoidance port 211 on the conical plate. Finally, it is pumped out by the water pump 22, which effectively improves the drying rate and facilitates the next step of the detection work.

[0043] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
