Abstract
Description
Technical Field
[0001] The utility model belongs to the field of river drainage outlet detection probes, in particular to a long-life river drainage outlet detection probe. Background Art
[0002] To monitor water quality at various river outlets and prevent sewage from entering the river, environmental protection authorities install probes at the outlets, connected to monitoring systems, to measure the pH of the water. These probes are typically installed above the river surface. Ideally, the sensing end of the probe should remain submerged. This ensures optimal operation and a long service life, as exemplified by the FU20-05-T1-NPT or PH2100 probes.
[0003] During normal storage, the detection end of the probe needs to be kept submerged. This is mainly because pH measurement uses the glass probe at the detection end to sense hydrogen ion concentration. The surface of the glass probe has a hydrated gel layer. The hydrated gel layer can only respond to hydrogen ions in water when it is fully moistened. This hydrated gel layer may be damaged if it is out of water for a long time. At the same time, the detection end of the probe has a sealant. Some sealants may crack when out of water for a long time, causing water ingress, which may also cause the detection probe's service life to be shortened.
[0004] Under actual working conditions, the water flow rate at the drain outlet is changing, and the liquid level in the drain outlet pipe will change. In the dry season, or at night when water consumption and drainage are low, the liquid level at the drain outlet will be lower than the detection end of the detection probe, and there may even be no water at the drain outlet, causing the detection end of the detection probe to be exposed to the air and more easily damaged. Utility Model Content
[0005] The purpose of the utility model is to provide a long-life river drainage outlet detection probe.
[0006] The utility model has the advantage of long service life.
[0007] The technical solution of the utility model is as follows: a long-life river drainage outlet detection probe, a sealed box body is provided on the outside of the detection end of the detection probe, a connecting mechanism corresponding to the river drainage outlet is provided on the box body, a water inlet hole is provided on the top of the box body, and a drainage pipe extending upward is provided on the side wall of the bottom of the box body.
[0008] In the aforementioned long-life river outlet detection probe, the connection mechanism includes a plurality of buckles distributed circumferentially around the water inlet hole, and the buckles are fixed to the top surface of the box body.
[0009] In the aforementioned long-life river drainage outlet detection probe, a rubber plate is provided at the water inlet, the outer edge of the rubber plate is fixed to the inner wall of the box, the middle of the rubber plate is provided with a cross-cutting seam, and a leakage hole with a diameter less than 5mm is provided at the intersection of the cutting seams.
[0010] In the aforementioned long-life river outlet detection probe, a groove is provided on the bottom surface of the rubber plate, and the cutting seam passes through the middle of the bottom surface of the groove.
[0011] In the aforementioned long-life river outlet detection probe, a float is provided in the drain pipe, the float is gap-fitted with the drain pipe, and a plurality of circumferentially distributed drainage holes are provided on the outer side wall of the upper end of the drain pipe.
[0012] In the aforementioned long-life river drainage outlet detection probe, the drainage hole is a long hole, the width of the drainage hole is less than half of the diameter of the float, and the length of the drainage hole exceeds the diameter of the float.
[0013] In the aforementioned long-life river outlet detection probe, a limit pin is provided at the upper end of the drain pipe to prevent the float from falling out.
[0014] In the aforementioned long-life river drainage outlet detection probe, the lower end of the drainage pipe is screwed to the box body, and the material of the drainage pipe is aluminum alloy.
[0015] Compared to the prior art, the present invention incorporates a housing outside the existing detection probe, with a water inlet at the top. After the housing is secured to the underside of the river drain outlet, water from the outlet can flow into the housing. The water stored in the housing allows the detection probe to be submerged in water for extended periods. Even if the outlet is shut off, the detection probe is not easily damaged, extending its service life. Therefore, the present invention offers the advantage of a longer service life.
[0016] By setting an upward extending drainage pipe on the box, the water entering the box at the river drainage outlet can be discharged, realizing water circulation, making the water quality in the box the same as the water quality at the river drainage outlet, avoiding detection errors and preventing the detection accuracy of the detection probe from being reduced.
[0017] By setting a rubber plate at the water inlet and setting a cross-cut seam and leakage hole at the rubber plate, it is ensured that the water at the river drainage outlet can smoothly enter the box body, while reducing the evaporation of water in the box body, thereby further ensuring that the detection probe can remain immersed for a long time, thereby improving the service life of the detection probe, and the size of the leakage hole can be changed, which can reduce the possibility of blockage, avoid new water from entering the box body, and prevent the detection accuracy of the detection probe from being reduced.
[0018] By setting a float on the drain pipe, the float is used to reduce the evaporation area of the drain pipe, further ensuring that the detection probe can remain immersed for a long time, thereby increasing the service life of the detection probe. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments, but they are not intended to limit the present invention.
[0025] Example 1. Long-life river outlet detection probe, such as Figure 1 As shown, a sealed box 2 is provided on the outside of the detection end of the detection probe 1, and the detection probe 1 is inserted from the bottom of the box 2. The detection probe 1 and the box 2 are sealed. The box 2 is cylindrical, and the top surface of the box 2 is an arc surface, so that the top surface of the box 2 can fit with the outer wall of the pipe 14 at the river drainage outlet. The wall thickness of the box 2 is 0.5 cm, the height is 15 cm, and the outer diameter is 8 cm. The box 2 is provided with a connecting mechanism corresponding to the river drainage outlet, and the top of the box 2 is provided with a water inlet 3, and the diameter of the water inlet 3 is 3 cm.
[0026] The connection mechanism includes six buckles 5 distributed circumferentially around the water inlet hole 3 , and the buckles 5 are fixed to the top surface of the box body 2 .
[0027] A rubber sheet 6, 5 mm thick and 4 cm in diameter, is installed at the water inlet 3. The outer edge of the rubber sheet 6 is fixed to the inner wall of the box 2. Cross-cut slits 7 are cut in the middle of the rubber sheet 6, forming four membrane flaps 13. Water leakage holes 8, each 4 mm in diameter, are located at the intersections of the slits 7. A groove 9 is provided on the bottom surface of the rubber sheet 6. The slits 7 pass through the middle of the bottom surface of the groove 9, and the minimum distance between the groove 9 and the top surface of the rubber sheet 6 is 1 mm. The grooves 9 in the rubber sheet 6 make the membrane flaps 13 thinner on the inside and thicker on the outside, resulting in better elasticity and more sensitive operation.
[0028] A drain pipe 4 extends upward from the sidewall of the bottom of the housing 2. Its inner diameter is 1 cm, and its upper end does not extend beyond the top surface of the housing 2. Its lower end is screwed to the housing 2. Made of aluminum alloy, it can be easily removed to clear any blockages. A float ball 10 with a diameter of 9.5 mm is located within the drain pipe 4. Four circumferentially distributed drain holes 11 are located on the outer sidewall of the upper end of the drain pipe 4. These holes are elongated, 4 mm wide, and 1.5 cm long. A stop pin 12 is located at the upper end of the drain pipe 4 to prevent the float ball 10 from dislodging.
[0029] Working principle: Drill a hole at the bottom of the pipe 14 at the outlet into the river, where the pipe 14 extends above the river surface. Move the box 2 from bottom to top and use the buckle 5 to fix the box 2 to the bottom of the pipe 14.
[0030] When there is a small water flow at the river outlet, some of the water in the pipe enters the housing 2 through the leak hole 8. When the water flow is large, the inner end of the diaphragm 13 rotates downward under the water pressure, causing the leak hole 8 to expand. Since the diaphragm 13 can rotate to change the diameter of the leak hole 8, the leak hole 8 is not easily blocked. The water in the housing 2 enters the drain pipe 4, and after the float 10 rises to a height exceeding the drain hole 11, the water in the drain pipe 4 is discharged from the drain hole 11. When there is no water at the river outlet, the four diaphragms 13 close to reduce the evaporation of water in the housing 2, and the float 10 descends to the inner side or lower side of the drain hole 11, reducing the evaporation of water in the drain pipe 4. Therefore, even if there is no water at the river outlet for a long time, the detection probe 1 can still be immersed in water, extending its service life.
[0031] Example 2. Compared with Example 1, the difference is that the detection end of the detection probe 1 is located at the lower part of the drain pipe 4, the detection probe 1 is inserted from the upper side of the drain pipe 4, and the detection probe 1 and the drain pipe 4 are sealed.
