Description

Technical Field

[0002] In order to monitor the water in the water pipeline in real time, the existing technology mainly opens a hole in the water pipeline and embeds a water quality detection sensor. The detection end of the water quality detection sensor is located on the inside of the water pipeline, so as to detect the water quality of the water flowing inside the water pipeline. However, the above structure still has some shortcomings. When the water quality detection sensor is immersed in water for a long time, a layer of impurities will adhere to the surface of the water quality detection sensor. If the water quality detection sensor is not cleaned for a long time, the impurities on the surface of the water quality detection sensor will accumulate more and more, affecting the water flow of the water pipeline on the one hand and the water quality detection result on the other hand. The conventional practice is to cut off the water flow in the water pipeline and then remove the water quality detection sensor for cleaning. Although this method can clean the water quality detection sensor, it requires stopping the water flow in the water pipeline. In addition, the water quality detection sensor may be damaged by bumps during the disassembly and assembly process, and the cleaning efficiency of the water quality detection sensor is low.

[0003] Therefore, how to provide a self-cleaning system for water quality testing that can overcome the above problems is an issue that needs to be urgently addressed by those skilled in the art. Utility Model Content

[0029] Example

[0030] See attached Figures 1-3 This is a schematic diagram of the overall and partial structures of an embodiment of the utility model. The utility model specifically discloses a self-cleaning system for water quality detection, which is installed on a water pipeline 1. Water is transported in the water pipeline 1, and a water quality detection sensor can detect the water in the water pipeline 1.

[0031] The self-cleaning system includes:

[0032] The limiting cylinder 2 has a circular cross-sectional outer contour, one end of which is open and the other end is closed. The open end of the limiting cylinder 2 is fixed to the outer wall of the water pipeline 1. The center line of the limiting cylinder 2 intersects with the center line of the water pipeline 1 and can be arranged vertically. A circular through hole is provided on the side wall of the water pipeline 1. The through hole is directly opposite to and connected to the limiting cylinder 2. The inner contour of the cross section of the limiting cylinder 2 is circular, and the inner diameter of the limiting cylinder 2 is the same as the aperture of the through hole.

[0033] The sliding member includes two slides 3 and multiple connecting members 4.

The multiple connecting members 4 are located between the two slides 3. The two ends of the connecting member 4 are respectively fixed to the two slides 3. The maximum distance between the two slides 3 is less than the depth of the limiting cylinder 2.

[0034] The water quality detection sensor is fixed on a slide 3. The water quality detection sensor is limited in the area defined by the two slides 3 and the multiple connecting parts 4. The outer walls of the two slides 3 can simultaneously slide and tightly contact with the inner wall of the limiting cylinder 2. When the outer walls of the two slides 3 are simultaneously in tight contact with the inner wall of the limiting cylinder 2, the water in the water pipe 1 will not enter between the two slides 3. Similarly, the liquid between the two slides 3 will not enter the water channel.

[0035] The telescopic member 8 is fixed on the limiting cylinder 2. After passing through the closed end of the limiting cylinder 2, the telescopic end of the telescopic member 8 is fixed to a slide 3 near the bottom wall of the limiting cylinder 2. The telescopic direction of the telescopic end of the telescopic member 8 is parallel to the center line of the limiting cylinder 2. The telescopic member 8 can drive the slide 3 and the connecting member 4 to move along the length direction of the limiting cylinder 2. A slide 3 near the bottom wall of the limiting cylinder 2 is always located in the limiting cylinder 2, and a slide 3 away from the bottom wall of the limiting cylinder 2 can be located in the water pipe 1.

[0038] The pump 11 can deliver the cleaning liquid into the limiting cylinder 2, and the cleaning liquid in the limiting cylinder 2 can be discharged from the liquid discharge port.

[0039] More specifically, a controller is further included. The controller is fixed on the outer wall of the limiting cylinder 2. The telescopic member 8, the ultrasonic generator 9, the pump 11 and the electric stop valve 12 are all electrically connected to the controller.

[0040] An air pressure balance hole 20 is provided at the closed end of the limiting cylinder 2. When the telescopic member 8 drives the slide 3 to move in the limiting cylinder 2, the space between a slide 3 close to the bottom wall of the limiting cylinder 2 and the bottom wall of the limiting cylinder 2 can be connected to the external atmosphere, ensuring that the slide 3 can slide smoothly in the limiting cylinder 2.

[0041] The telescopic part 8 is a telescopic cylinder, which is fixed to the outer wall of the closed end of the limiting cylinder 2. A clearance hole is provided in the center of the outer wall of the closed end of the limiting cylinder 2.

[0043] A cleaning port is provided on the side wall of the limiting cylinder 2, and a plug 13 is removably sealed at the cleaning port; when the outer walls of the two slides 3 are in close contact with the inner wall of the limiting cylinder 2 at the same time, the cleaning port is located between the two slides 3. This design facilitates cleaning the area between the two slides 3 and is conducive to the discharge of residues.

[0044] The water quality detection sensor is fixed on a slide plate 3 near the bottom wall of the limiting cylinder 2. A wire threading hole 30 is provided on the surface of the slide plate 3 near the bottom wall of the limiting cylinder 2. The wires of the water quality detection sensor are tightly passed through the wire threading hole 30. The closed end of the limiting cylinder 2 is also provided with a mounting hole for threading, and the wires of the water quality detection sensor are also passed through the mounting hole. This design facilitates the electrical connection of the water quality detection sensor with the controller outside the limiting cylinder 2.

[0045] The water quality detection sensor includes a temperature sensor 5 , a pH value sensor 6 and a dissolved oxygen sensor 7 . The water quality detection sensor can detect the temperature, pH value and dissolved oxygen capacity of the water in the water pipeline 1 .

[0047] When it is necessary to clean the dirt attached to the surface of the water quality detection sensor:

[0048] In the first step, the telescopic member 8 drives the two slides 3 to move forward, and the slides 3 begin to approach the bottom wall of the limiting cylinder 2. After the slides 3 move a certain distance, the outer walls of the two slides 3 are in close contact with the inner wall of the limiting cylinder 2 at the same time;

[0049] In the second step, the electric stop valve 12 and the pump 11 are opened in sequence, and the cleaning liquid is filled into the area between the two slides 3 in the limiting cylinder 2 by using the pump 11. The electric stop valve 12 and the pump 11 continue to work for a period of time to ensure that all the water in the limiting cylinder 2 and between the two slides 3 is drained, so that the area between the two slides 3 in the limiting cylinder 2 is fully filled with the cleaning liquid. At this time, the pump 11 and the electric stop valve 12 are closed. After the power is turned off, the pump 11 is in a state of disconnected liquid circuit, that is, the cleaning liquid will not flow through the pump 11 after the power is turned off;

[0050] In the third step, the ultrasonic generator 9 is powered on, and the ultrasonic wave generated by the ultrasonic transducer 10 is transmitted to the cleaning liquid in the limiting cylinder 2, thereby ultrasonically cleaning the water quality detection sensor;

[0051] Step 5: After ultrasonic cleaning for a period of time, the electric stop valve 12 is opened, and the pump 11 is started after the liquid inlet end of the pump 11 is connected to the external clean water source. The pump 11 is used to fill clean water into the area between the two slides 3 in the limiting cylinder 2, thereby discharging the cleaning liquid in the area between the two slides 3 in the limiting cylinder 2;

[0052] In the sixth step, the telescopic member 8 drives the two slides 3 to move in the opposite direction, and the water quality detection sensor and the slide 3 are reset.
