Description

Technical Field

[0001] The invention belongs to the technical field of water meter withstand voltage detection, in particular to a water meter withstand voltage detection device. Background Art

[0002] A water meter is an instrument that measures water flow, most of which measure the cumulative flow of water. It is generally divided into two categories: volumetric water meter and velocity water meter. Before leaving the factory, water meters are usually tested for pressure resistance using a pressure testing device to select water meters that do not meet quality standards.

[0003] A patent with publication number CN116878621A discloses a pressure resistance detection device for water meter production. The invention starts the cylinder, and the output end of the cylinder drives the bottom plate to move downward, so that the bottom plate drives the movable beam to move downward. The movable beam moves downward along the slide rail through the U-shaped rails at both ends, thereby realizing the fixed clamping between the arc clamp and the flexible circular clamp. The cylinder drives the flexible circular clamp to continuously pressurize the arc clamp, thereby realizing the effect of surface pressure test of the water meter. The gas of the air pump is transmitted to the booster pump through the air guide pipe. The booster pump receives the external gas and pressurizes the ventilation column below at the same time. The pressurized gas is transported to the inside of the flexible circular clamp through the ventilation pipe, and finally filled into the air bag inside the flexible circular clamp. The air pressure generated by the air bag to the outside world squeezes the bottom wall of the flexible circular clamp, thereby increasing the pressure received by the water meter surface and enhancing the effect of the water meter pressure test.

[0004] There are still some problems in the actual application of the above scheme. Usually, one end of the water meter is sealed first, and then a rated air pressure is injected into the water meter from the other end using an air pump. After the air pressure reaches a stable value, the pressure pointer of the water meter is observed to see if it jumps and drops, so as to determine whether there is over-pressure leakage in the water meter after being subjected to the rated pressure. However, this detection method is not only cumbersome, but also unable to quickly determine whether there is over-pressure leakage in the water meter itself, or over-pressure leakage caused by insufficient sealing at the connection port.

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1

[0035] like Figures 1 to 7 As shown, a water meter withstand voltage detection device according to an embodiment of the present invention comprises a detection box 1, a placement opening 3 is provided on the upper end surface of the detection box 1, two partition plates 4 are installed in the inner cavity of the detection box 1, and the two partition plates 4 separate the two sides of the inner cavity of the detection box 1 into water storage chambers 12, a detection chamber 13 is provided between the two partition plates 4, and a slide plate 14 is slidably connected between the two partition plates 4, and two clamping and positioning components 6 are symmetrically installed on the upper end surface of the slide plate 14;

[0036] The clamping and positioning assembly 6 includes two fixing blocks 61 symmetrically mounted on the slide plate 14, and the two fixing blocks 61 are provided with sealing grooves 63 inside, the inner cavity of the sealing groove 63 is slidably connected with a slide rod 62, one end of the slide rod 62 is fixedly connected with a clamping plate 66, and one side of the clamping plate 66 is provided with a docking port 67, and the inner wall of the docking port 67 is provided with two rubber rings 26;

[0037] The docking port 67 is used to dock with the two end joints of the water meter 5 . One end of the slide bar 62 is arranged in a semicircular arc shape. Four limiting columns 23 are symmetrically fixedly connected to the upper end surface of the slide plate 14 , and the four limiting columns 23 are used to limit the water meter 5 .

[0038] Specifically, in the prior art, one end of the water meter is usually sealed first, and then a rated air pressure is injected into the water meter from the other end using an air pump. After the air pressure reaches a stable value, the pressure pointer of the water meter is observed to see if it jumps and drops, thereby determining whether the water meter has overpressure leakage after being subjected to the rated pressure. However, this detection method is not only cumbersome, but also inefficient, affecting the efficiency of the water meter production pressure resistance detection.

[0039] The present invention installs the water meter 5 between the limit columns 23, and uses the limit columns 23 to limit and calibrate the position of the water meter 5, so that the water inlet and outlet of the water meter 5 are aligned with the docking port 67, and then drives the slide plate 14 to move downward, and then the slide plate 14 drives the fixed block 61 to move downward. During the downward movement of the fixed block 61, the slide bar 62 is driven to move synchronously, and one end of the slide bar 62 is set in a semicircular arc shape, and then during the downward movement of the slide bar 62, it will contact the upper end of the partition plate 4, and then cooperate with the partition plate 4 to squeeze the slide bar 62 to slide into the inner cavity of the sealing groove 63, and then the slide bar 62 pushes the clamping plate 66 to squeeze and fix the water meter 5, so as to realize the extrusion detection of the surface of the water meter 5, and the clamping plate 66 is inserted into the water inlet and outlet of the water meter 5 by using the docking port 67, and the inner wall of the docking port 67 is provided with two rubber rings 26, so that when the water inlet and outlet of the water meter 5 are inserted into the inner cavity of the docking port 67, it can squeeze The rubber ring 26 on the inner wall of the docking port 67 increases the sealing performance of the docking port 67, and then the specified air pressure is filled into the water meter 5 through the docking port 67 by using an external air pump, and the pressure pointer of the water meter 5 is observed to stop the operation of the air pump after reaching the maximum critical value, and then observe whether the pressure pointer of the water meter 5 decreases, so as to determine whether there is over-pressure leakage in the water meter 5 after bearing the rated pressure, and when the slide plate 14 moves downward and slides into the bottom of the inner cavity of the detection box 1, the water storage chamber 12 will be opened to discharge clean water into the detection chamber 13, and the clean water will cover the water meter 5, and then after the rated pressure is injected into the water meter 5, if the water meter 5 leaks, bubbles will be ejected from the clean water, so as to better observe the pressure relief and leakage position of the water meter 5, so as to facilitate determination of whether the water meter body is leaking or the over-pressure leakage caused by unstable sealing of the water meter interface.

[0040] like Figure 1 , Figure 3 and Figure 7 As shown, drawers 2 are slidably connected to both sides of the detection box 1, mesh holes are evenly arranged at the bottom of the inner cavity of the drawer 2, a filter plate 15 is fixedly connected to the water storage cavity 12, a triangular guide block 16 is installed at the bottom of the inner cavity of the water storage cavity 12, and a handle groove 11 is opened on one side of the drawer 2.

[0041] like Figure 1 , Figure 3 and Figure 7 As shown, a water inlet 24 is provided inside the partition plate 4 , a receiving groove 17 is provided on the inner wall of the water inlet 24 , a sealing plate 18 is slidably connected to the inner cavity of the receiving groove 17 , and a T-shaped sliding column 7 is fixedly connected to the lower end of the sealing plate 18 .

[0042] like Figure 3 and Figure 7 As shown, a tension spring 10 is fixedly connected to the lower end surface of the detection box 1, one end of the tension spring 10 is fixedly connected to the T-shaped sliding column 7, two abutments 19 are fixedly connected to one side of the sealing plate 18, a groove 20 is provided on the side wall of the receiving groove 17, a waterproof rubber layer is provided on the outside of the sealing plate 18, and it slides in the inner cavity of the receiving groove 17 with an interference fit to seal the water inlet 24.

[0043] Specifically, after the water meter 5 is installed between the two fixing blocks 61, the slide plate 14 is driven to slide and move downward in the detection cavity 13, and then the slide plate 14 drives the fixing block 61 to move downward, and then drives the slide bar 62 to move synchronously. During the downward movement of the slide bar 62, it will contact the upper end of the partition plate 4, and then cooperate with the partition plate 4 to squeeze the slide bar 62 into the inner cavity of the sealing groove 63, and then the slide bar 62 pushes the clamping plate 66 to squeeze and fix the water meter 5, and at the same time, the docking port 67 is used to insert the water inlet and outlet of the water meter 5 into the fixed connection, and then the water meter 5 is connected to the water inlet and outlet of the water meter 5. The water meter 5 is clamped and fixed, and the lower end of the slide plate 14 abuts against the stop block 19 while the slide plate 14 moves downward, and then the sealing plate 18 is pushed downward, so that the sealing plate 18 slides into the inner cavity of the storage groove 17. After the slide plate 14 pushes the stop block 19 to slide into the inner cavity of the groove 20, the sealing plate 18 and the slide plate 14 are kept at the same horizontal plane, and then the water inlet 24 is opened, so that the clean water in the water storage chamber 12 is poured into the detection chamber 13, thereby covering and overflowing the water meter 5, so as to better observe the bubbles generated in the clean water. The position of the water meter 5 for decompression and leakage is determined. After the water meter 5 is detected, the slide plate 14 is driven to move upward, and the slide plate 14 will lift the clean water and move upward. During the upward movement of the slide plate 14, the tension spring 10 is used to pull the T-shaped slide column 7 upward, and then the T-shaped slide column 7 pushes the sealing plate 18 to slide out of the storage groove 17 and seal the water inlet 24. After the slide plate 14 moves to the same horizontal plane as the partition plate 4, the clean water will flow back into the water storage chamber 12, and the drawer 2 and the filter plate 15 will be used to filter the clean water, thereby improving the clean water. The clarity is improved to facilitate better observation of the leakage position of the water meter through clear water, thereby solving the problem that after the rated air pressure is injected into the water meter, the existing water meter pressure resistance detection device observes whether the pressure pointer of the water meter jumps and decreases to determine whether there is over-pressure leakage in the water meter after bearing the rated pressure. However, this detection method cannot accurately determine whether the over-pressure leakage is caused by loose sealing at the water inlet and outlet of the water meter, or whether there is over-pressure leakage in the water meter body, resulting in the inability to accurately determine the quality of the water meter, affecting the accuracy of the water meter pressure resistance detection.

[0044] Embodiment 2

[0045] like Figure 2 , Figure 6 and Figure 7 As shown, the lower end surface of the slide plate 14 is fixedly connected to two folding air pumps 22, and the lower ends of the two folding air pumps 22 are fixedly connected to a fixed cover 8, the fixed cover 8 is fixedly installed on the lower end surface of the detection box 1, the lower end surface of the fixed cover 8 is provided with an air inlet 27, and the inner cavity of the air inlet 27 is provided with a one-way valve.

[0046] Specifically, by driving the slide plate 14 to move upward, and making the slide plate 14 drive the folding air pump 22 to move upward, while the folding air pump 22 moves upward, a negative pressure will be formed in the inner cavity, thereby opening the one-way valve in the inner cavity of the air inlet 27, and drawing external air into the folding air pump 22. After the slide plate 14 drives the folding air pump 22 to reset, the folding air pump 22 will extract a fixed amount of air, and then wait for the next pressure resistance test of the water meter 5. In addition, while the slide plate 14 moves upward, it will also support the clean water in the detection cavity 13 and discharge the clean water into the water storage cavity 12 through the partition plate 4. At the same time, the drawer 2 and the filter plate 15 in the water storage cavity 12 are used to filter and purify the clean water, so as to ensure the clarity of the clean water and avoid the problem of turbidity caused by not replacing the clean water for a long time, which affects the pressure resistance test of the water meter.

[0047] like Figure 5 , Figure 6 and Figure 7 As shown, an air guide cavity 25 is provided inside the fixed block 61 , and a one-way valve is installed in the air guide cavity 25 , and the one-way valve can only be flipped upward to open, and one end of the foldable air pump 22 passes through the slide plate 14 and is connected to the air guide cavity 25 .

[0048] Specifically, in the process of driving the slide plate 14 to move downward, the slide plate 14 will squeeze the folding air pump 22, and the air in the folding air pump 22 will form pressure to open the one-way valve in the air guide cavity 25, so that the air in the folding air pump 22 will be discharged into the air guide cavity 25 and flow into the water inlet meter 5, so that the air filled in the inner cavity of the water meter 5 can be used for pressure resistance detection, thereby improving the efficiency of the water meter pressure resistance detection.

[0049] like Figure 2 , Figure 5 and Figure 7 As shown, an electric push rod 9 is installed at the bottom of the inner cavity of the detection box 1, and a bracket 21 is fixedly connected to the piston rod end of the electric push rod 9, and the bracket 21 is fixedly installed and connected to the slide plate 14.

[0050] like Figure 5 , Figure 6 and Figure 7 As shown, a telescopic tube 69 is fixedly connected to one side of the clamping plate 66 , and the telescopic tube 69 is slidably connected in the air guide cavity 25 . A sealing rubber is provided on the outside of the telescopic tube 69 , and the telescopic tube 69 is plugged into the air guide cavity 25 with an interference fit.

[0051] like Figure 1 , Figure 5 and Figure 7 As shown, a spring 65 is fixedly connected to the inner wall of the sealing groove 63 , a support block 64 is fixedly connected to one end of the spring 65 , and the support block 64 is fixedly connected to the slide rod 62 .

The clamping and fixing, when the clamping plates 66 are close to each other to clamp the water meter 5, the clamping plates 66 will drive the pressing block 68 to move synchronously, and then the pressing block 68 presses and fixes the upper end of the water meter 5, thereby solving the problem that when the existing water meter pressure resistance detection device performs a pressure resistance test on the water meter, if the water meter is not clamped and fixed, it will cause the water meter to vibrate due to excessive air pressure when air pressure is injected into the water meter for pressure resistance test, causing the interface and the water inlet and outlet of the water meter to fall off and loosen, affecting the water meter pressure resistance test result.

[0054] The working principle is to install the water meter 5 between the limit columns 23, and use the limit columns 23 to limit and calibrate the position of the water meter 5, so that the water inlet and outlet of the water meter 5 are aligned with the docking port 67, and then drive the slide plate 14 to move downward, and then the slide plate 14 drives the fixed block 61 to move downward, and during the downward movement of the fixed block 61, it will drive the slide bar 62 to move synchronously, and one end of the slide bar 62 is set in a semicircular arc shape, and then during the downward movement of the slide bar 62, it will contact the upper end of the partition plate 4, and then cooperate with the partition plate 4 to squeeze the slide bar 62 into the inner cavity of the sealing groove 63, and then the slide bar 62 pushes the clamping plate 66 to squeeze and fix the water meter 5, and the clamping plate 66 is inserted into the water inlet and outlet of the water meter 5 by using the docking port 67, and the inner wall of the docking port 67 is provided with two rubber rings 26, and then when the water inlet and outlet of the water meter 5 are inserted into the inner cavity of the docking port 67, the rubber ring 26 on the inner wall of the docking port 67 can be squeezed, so that the rubber ring 26 increases the sealing performance at the docking port 67;

[0055] By installing the water meter 5 on the slide plate 14, and then starting the electric push rod 9 to drive the bracket 21 to move downward, the bracket 21 drives the slide plate 14 to move downward, so that the slide bar 62 contacts the upper end of the partition plate 4, and then cooperates with the partition plate 4 to squeeze the slide bar 62 to slide into the inner cavity of the sealing groove 63, so that the slide bar 62 pushes the clamping plate 66 to drive the telescopic tube 69 to slide out of the air guide cavity 25, and then the clamping plate 66 is inserted into the outside of the water inlet and outlet of the water meter 5 through the docking port 67, and the water meter 5 is clamped and fixed. When the clamping plates 66 are close to each other to clamp the water meter 5, the clamping plates 66 will drive the pressing block 68 to move synchronously, and then the pressing block 68 presses and fixes the upper end of the water meter 5;

[0056] After the water meter 5 is installed between the two fixing blocks 61, the slide plate 14 is driven to slide and move downward in the detection cavity 13, and then the slide plate 14 drives the fixing block 61 to move downward, and then drives the slide bar 62 to move synchronously.
