Description

Technical Field

[0001] The invention belongs to the field of water meters, and in particular relates to a water meter load detection device for simulating the use environment of the water meter. Background Art

[0002] A water meter is an instrument for measuring water flow, most of which measure the cumulative flow of water. It is generally divided into two categories: volumetric water meters and velocity water meters. It originated in the UK and has a history of nearly two hundred years. When choosing the specifications of a water meter, you should first estimate the size and range of the flow rate normally used, and then choose the water meter with the specification that is closest to the commonly used flow rate as the first choice.

[0003] At present, water meters have been widely used in all walks of life. With the rapid development of electronic information technology, electronic water meters have gradually become the development direction of the water meter industry. Enterprises or measurement departments that produce water meters need to perform performance verification of the indication error of these water meters according to the verification procedures formulated by relevant departments.

[0004] The collection method is the most commonly used detection method. It collects the water flowing through the water meter to be tested into one or several containers, and uses the static volume method or static weighing method to measure the water volume in the container. The calibration personnel need to manually switch the water flow three times, read the water meter reading four times, and read the water level of the standard measuring instrument three times. Manually record these data and calculate various errors and compare them with the water meter indication to determine the indication error of the water meter. During the entire calibration process, the calibration personnel need to control the operation of the calibration device in real time. When reading various indications manually, they need to close the valve and wait for the liquid level in the standard metal measuring instrument to stabilize. The stability of these start and stop stages, the interpretation error of the liquid level reading, the resolution of the indication scale of the water meter being tested, and human factors will affect the calibration accuracy.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] Since the existing water meters use manual visual data when detecting accuracy, there is a certain error in the detected accuracy. Therefore, we fix the water meter with abutment mechanism, and rotate the rotating plate at a certain angle under the action of the lifting component, so that the liquid level heights of the water discharge tank and the water collection tank change. Under the principle of communicating vessels, the water in the water discharge tank flows through the water meter to the water collection tank. After stabilization, the value on the detection rod is directly read and compared with the value displayed on the water meter. At the same time, in order to avoid the contingency of a single measurement, the lifting component restores the rotating plate to a horizontal level for the next test. In the process of the lifting component restoring the level, the reflux component can make the water in the water collection tank flow back to the water discharge tank, ensuring that in the initial state, the liquid levels of the water discharge tank and the water collection tank remain at the same height.

[0039] In order to effectively illustrate the embodiments of the present invention, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0040] See also Figure 1-5 The present invention provides a water meter load detection device that simulates the water meter use environment to solve the problem of human error in the water meter accuracy detection process.

[0041] An embodiment of the present invention provides a water meter load detection device for simulating a water meter use environment, comprising:

[0042] A base 1, wherein the base 1 is a rectangular parallelepiped structure, and a mounting frame 2 is fixed on the upper part thereof, a rotatable rotating plate 3 is provided on the base 1, and an abutment mechanism for fixing a water meter is provided on the rotating plate 3, the abutment mechanism is connected and conducted with the water meter, and the abutment mechanism is connected and conducted with a liquid discharge assembly provided on the mounting frame 2;

[0043] The abutment mechanism includes a first drive device 4 fixedly mounted on the rotating plate 3, a bidirectional drive assembly arranged on the rotating plate 3 and connected to the output shaft of the first drive device 4, and two sets of elastic sealing assemblies connected to the bidirectional drive assembly and symmetrically arranged;

[0044] The elastic sealing component is connected and communicated with the liquid discharge component through a hose;

[0045] The bidirectional driving assembly includes a bidirectional screw rod 5 rotatably mounted on the rotating plate 3, and two No. 1 threaded sleeves 6 symmetrically arranged on the bidirectional screw rod 5;

[0046] The rotating plate 3 is provided with a through groove along its length direction, and a connecting piece 7 penetrating the through groove is fixedly mounted on the No. 1 threaded sleeve 6, and the connecting piece 7 is connected to the elastic sealing assembly;

[0047] The elastic sealing assembly includes a connecting pipe 8 which is hollow inside and connected to the connecting piece 7, a rubber pad 11 sleeved on the connecting pipe 8, and a spring 10 sleeved on the connecting pipe 8;

[0048] The connecting tube 8 is provided with limiting rings 9 on both sides of the connecting piece 7 to abut against it, one end of the spring 10 is connected to the limiting ring 9, and the other end is connected to the rubber pad 11, and a protrusion 12 for limiting the rubber pad 11 is provided on the connecting tube 8.

[0049] When in use, by controlling the rotation of the No. 1 driving device 4, the bidirectional screw 5 is driven to rotate, so that the No. 1 threaded sleeve 6 threadedly matched with the bidirectional screw 5 moves toward each other in the axial direction of the bidirectional screw 5 until the rubber pad 11 is tightly fitted with both ends of the water meter.

[0050] Among them, the two-way screw rod 5 and the No. 1 threaded sleeve 6 are threadedly matched, so that when the two ends of the water meter are tightly fitted with the rubber pad 11, even if the No. 1 drive device 4 is powered off and stops working, the rubber pad 11 will not be separated from the water meter, thereby ensuring the precision of the connection between the two.

[0051] The two ends of the rotating plate 3 are respectively connected to the liquid discharge assembly through two symmetrically arranged No. 2 connecting rods 17;

[0059] The No. 2 threaded sleeve 15 is connected to one end of the rotating plate 3 via a No. 1 connecting rod 16 .
