Description

Technical Field

[0001] This utility model relates to the field of probe cleaning technology, and in particular to a probe cleaning device for a water quality tester. Background Technology

[0002] Water quality analyzers are professional instruments used to analyze the content of water components, measuring parameters such as BOD, COD, ammonia nitrogen, total phosphorus, total nitrogen, turbidity, pH, and dissolved oxygen. The probe, being the component that directly contacts the water, is highly susceptible to contamination from various pollutants. To avoid cross-contamination and ensure the accuracy of subsequent test results, it is typically cleaned and maintained under current conditions.

[0003] Existing probe cleaning methods often employ a device such as the probe cleaning device for online water quality monitoring instruments disclosed in announcement number CN214441424U. This device moves the probe by an electric push rod, allowing it to enter the cleaning tank. Cleaning solution is added to the tank through an inlet pipe, and ultrasonic cleaning is performed using an ultrasonic generator. Although this device uses ultrasonic technology to drive water flow to rinse the probe, the probe remains stationary and in constant contact with the water, making it difficult to remove adhering contaminants. Furthermore, the probe is only fixed using a compression spring, which makes the limiting structure prone to loosening under the vibration of the ultrasonic waves. Additionally, the probe's positional stability cannot be guaranteed under the impact of water flow, making it highly susceptible to detachment from the cleaning instrument. Utility Model Content

[0004] The purpose of this invention is to solve the problem that static cleaning of the probe affects the cleaning effect in the prior art, and to propose a probe cleaning device for water quality testing instruments.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A probe cleaning device for a water quality analyzer includes a housing filled with cleaning fluid. A load-bearing bracket is integrally connected to one side of the housing. A drive shaft is rotatably mounted on the load-bearing bracket. A transmission shaft is rotatably mounted on the housing. A load-bearing shaft is movably disposed within the housing. A lock for fixing the probe and intermittently immersing it in the cleaning fluid is fixedly connected to the load-bearing shaft. The housing and the load-bearing bracket are equipped with a drive mechanism that drives the load-bearing shaft to spirally lift and lower via the drive shaft and the transmission shaft.

[0007] Preferably, an operation window is provided on the front side of the chassis.

[0008] Preferably, the driving mechanism includes an inclined roller fixedly mounted on the driving shaft, a right-angle lifting frame that slidably abuts the inclined roller and is used to rotatably mount the load-bearing shaft is slidably mounted on the load-bearing bracket, a pulley is connected between the driving shaft and the transmission shaft via a sprocket, and a driving gear column and a driven gear are respectively keyed to the transmission shaft and the load-bearing shaft for meshing connection.

[0009] Preferably, the top of the inclined roller has a cut surface, and the thickness of the drive gear column is three times the thickness of the driven gear.

[0010] Preferably, the lock includes a countersunk sleeve fixedly connected to a load-bearing rotating shaft, a sloping lifting cover threaded onto the countersunk sleeve, a receiving hole in the countersunk sleeve, a return spring welded to the outside of the receiving hole, a limiting clamp fixedly connected to the return spring, which is slidably fitted into the receiving hole and extends movably into the countersunk sleeve, and a wedge head integrally connected to the limiting clamp that movably abuts against the sloping lifting cover.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. This utility model features an integrated chassis and load-bearing bracket. The load-bearing bracket and chassis house a drive shaft, a transmission shaft, and a load-bearing shaft. A drive mechanism is installed between the drive shaft, the transmission shaft, and the load-bearing shaft. The load-bearing shaft is reciprocated by using an inclined roller and a right-angle lifting frame, and rotated by using a drive gear column and a driven gear.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-4 A probe cleaning device for a water quality analyzer includes a housing 1 filled with cleaning fluid. An openable and closable operating window is provided on the front side of the housing 1. The level of the cleaning fluid is always below the operating window, allowing the probe to be retrieved and stored inside the housing 1. A load-bearing bracket 2 is integrally connected to one side of the housing 1. A drive shaft 3 is rotatably mounted on the load-bearing bracket 2. Notably, a drive motor is provided on the load-bearing bracket 2 to drive the drive shaft 3 to rotate. A transmission shaft 4 is rotatably mounted on the housing 1, and a load-bearing shaft 5 is movably disposed within the housing 1. Under the drive of the drive motor, the drive shaft drives the transmission shaft 4 to rotate, and in turn, drives the load-bearing shaft 5 to perform a spiral lifting motion.

[0022] A locking device 6 is fixedly connected to the load-bearing rotating shaft 5 to secure the probe and intermittently immerse it in the cleaning solution. See the instruction manual for details. Figure 2 With appendix Figure 4 The lock 6 includes a countersunk sleeve 61 fixedly connected to the load-bearing rotating shaft 5. A sloping lifting cover 62 is threaded onto the countersunk sleeve 61. A receiving hole 63 is provided in the countersunk sleeve 61. A return spring 64 is welded to the outside of the receiving hole 63. A limiting clamp 65 is fixedly connected to the return spring 64, which is slidably fitted into the receiving hole 63 and extends movably into the countersunk sleeve 61. A wedge head 66 that moves against the sloping lifting cover 62 is integrally connected to the limiting clamp 65. It should be noted that a through hole for installing a locking screw is provided in the sloping lifting cover 62, so as to limit and fix the sloping lifting cover 62 when it is raised to a certain position. The sloping lifting cover 62 applies pressure to the circumferentially distributed limiting clamps 65, and the probe is locked and fixed by the limiting clamps 65 that retract into the countersunk sleeve 61.

[0023] The chassis 1 and the load-bearing bracket 2 are equipped with a drive mechanism 7 that drives the load-bearing shaft 5 to lift and lower in a spiral manner via a drive shaft 3 and a transmission shaft 4. See the attached instruction manual for details. Figure 2 With appendix Figure 3 The drive mechanism 7 includes an inclined roller 71 fixedly mounted on the drive shaft 3. A right-angle lifting frame 72, which is slidably mounted on the load-bearing bracket 2 and is used to rotate and mount the load-bearing shaft 5, is movable against the inclined roller 71. During rotation, the inclined roller 71 supports the right-angle lifting frame 71 to move vertically, so that the load-bearing shaft 5 moves synchronously within the housing 1. A pulley 73 is connected between the drive shaft 3 and the transmission shaft 4 via a sprocket. The transmission shaft 4 and the load-bearing shaft 5 are respectively keyed with a meshing drive gear column 74 and a driven gear 75. During the lifting motion, the load-bearing shaft 5 drives the driven gear 75 to always mesh with the drive gear column 74. Under the drive of the transmission shaft 4, the load-bearing shaft 5 rotates, thereby realizing the spiral lifting motion of the load-bearing shaft 5, so that the probe and the cleaning fluid make intermittent contact, and at the same time, the centrifugal force is used to accelerate the separation of contaminants adhering to the probe.

[0024] The inclined roller 71 has a cut surface at the top end, and the thickness of the drive gear column 74 is three times the thickness of the driven gear 75, ensuring that the driven gear 75 is always meshed with the drive gear column 74 during rotation.

[0025] The inclined lifting cover 62 has a cut surface at the bottom, which limits the movement of the wedge head 66 during the spiral downward movement, and the limiting clamp 65 has a T-shaped structure.

[0026] It should be noted that the specific model and specifications of the drive motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0027] The functional principle of this utility model can be explained through the following operation methods:

[0028] The probe is fitted into the countersunk sleeve 61 through the operation window. The inclined lifting cover 62 is controlled to move down spirally on the countersunk sleeve 61. The wedge head 66 applies pressure to the limiting clamp 65, and the limiting clamp 65 clamps and fixes the probe fitted into the countersunk sleeve 61.

[0029] The drive shaft 3 is controlled to rotate. The drive shaft 3 drives the right-angle lifting frame 72 to move vertically up and down through the inclined roller 71. At the same time, the drive shaft 3 drives the transmission shaft 4 to rotate through the pulley 73. The load-bearing shaft 5, which moves vertically up and down, achieves rotational motion through the driven gear 75 and the drive gear column 74, so that the lock 6 drives the probe to move spirally up and down in the housing 1, thereby achieving dynamic contact between the probe and the cleaning fluid.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
