technical field

The utility model relates to the technical field of water meter manufacturing, in particular to a detection water meter with a self-contained protection function.

Background technique

In the field of water meter management, the existing water meters are mainly used to detect water volume, which has been difficult to meet people's pursuit of intelligent technology life. With the acceleration of the pace of life and the development of technology, more humanized functions such as the detection of water pollution , residual chlorine detection, PH value detection or TDS detection and other tests came into being. Most of the existing detection is to fix the sensor in the water meter and contact with water for a long time. Once the time is long, the surface of the probe on the sensor is easy to form scale, which in turn affects the detection sensitivity of the sensor and even the detection result, and shortens its service life.

Detailed ways

The following describes in detail the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to be used to explain the present invention, but should not be construed as a limitation of the present invention.

The present utility model will be further described below with reference to the accompanying drawings and specific embodiments.

Referring to FIG. 1 , a detection water meter with its own protection function includes a water meter body 1, and the water meter body 1 is provided with a water inlet pipe 2 and a water outlet pipe 3, and above the water inlet pipe 2 or the water outlet pipe 3 are provided The sensor cavity 4, the sensor cavity 4 is provided with a protective plug 5 and a piston 1 6, the protective plug 5 is stuck at the bottom of the sensor cavity 4, and the protective plug 5 is provided with two probe holes, The piston one 6 is embedded with a sensor 7. In order to facilitate the manufacture of the sensor 7 and the piston one 6, an integrated structure is designed. The sensor 7 is connected with two probes 71, and the probes 71 can move along the probe. The principle of the hole moving up and down is to control the rise or fall of the sensor 7 through the rise or fall of the piston one 6, and then drive the probe 71 to pass through the probe hole on the protective plug 5 or retract the probe on the protective plug 5. On the side of the hole, when testing is required, the probe 71 is passed out of the protective plug 5 to contact water. When no testing is required, the probe 71 is raised and retracted to the protective plug 5 side to avoid contact with water to form self-protection.

When no water is used, the water in the water inlet pipe 2 or the water outlet pipe 3 does not flow, and the sensor 7 cannot detect it. In order to enable the sensor 7 to detect at any time, a branch water pipe 8 is connected to the water inlet pipe 2 or the water outlet pipe 3. , the branch water pipe 8 is sequentially connected with the piston cavity 9 and the sensor cavity 4 along the water flow direction. The control piston 10 is pressed down to cause the water in the branch water pipe 8 to flow, so that the probe 71 on the sensor 7 penetrates the protective plug 5 and contacts the water in the branch water pipe 8 for detection.

In order to make the water flow effect in the branch water pipe 10 good, and at the same time to facilitate the design and installation, the branch water pipe 10 is inclined and arranged on the water inlet pipe 2 or the water outlet pipe 3, and is horizontally arranged on the water inlet pipe 2 or the water outlet pipe 3, and the branch pipe 10 is arranged on the water inlet pipe 2 or the water outlet pipe 3. The flow effect in the water pipe 10 is not good; the vertical arrangement takes up many positions of the water inlet pipe 2 or the water outlet pipe 3, which is not conducive to the placement of other components on the water meter.

In order to make the water flow effect in the branch water pipe 10 good, the branch water pipe 10 and the piston cavity 9 are connected through the curved water channel 11, and the direction of the water flow in the branch water pipe 10 is consistent with the direction of the water flow in the curved water channel 11, so that The downward pressure of the second piston 10 can push all the water in the branch water pipe 10 to flow to the side of the piston cavity 9 .

According to customer requirements, the sensor 7 is one of a turbidity sensor, a residual chlorine sensor, a pH sensor or a TDS sensor.

The utility model utilizes the lifting and lowering of the sensor to make the probe penetrate one side of the protective plug for corresponding detection or retract to the other side of the protective plug for self-protection, which can effectively prevent the probe on the sensor from contacting water for a long time to form scale, thereby realizing self-protection. protection and prolong its service life.

The above are only preferred embodiments of the present utility model, and are not intended to limit the technical scope of the present utility model.
