Detailed ways

The utility model will be further described below.

Embodiment 1: As shown in FIGS. 1 and 3 , a magnetic liquid level gauge with a sound and light alarm function includes a liquid level gauge body 1 and an audible and light alarm device 2 . The liquid level gauge body 1 includes a tube body 11 and a magnetic float 12 inside the tube body 11, wherein the tube body 11 is provided with marks for reflecting the liquid level. Sound light alarm 2 includes sound light alarm module 21, shell 24, magnetic switch 22 in the shell 24 and power module 23, shell 24 is fixed on the tube body 11 through the connector, the sound light alarm device 2 is fixed on The outer side of the casing 24 is convenient for the transmission of sound and light signals. Magnetic switch 22, power module 23, sound and light alarm module 21 through the wire connecting through the wire, of which magnetic switch 22 is in a regular open state, magnetic switch 22 and magnetic floatingzer 12 can form a magnetic link to make the magnetic switch 22 closed. After the magnetic switch 22 is closed, the sound light alarm module 21 issues a sound and light alarm signal. When the sound and light alarm signal is issued, the operator can know whether the liquid level is in high, low, high, and low state; Light signal reminds on -site inspections and operators to know what the liquid level is in.

As shown in Figure 2 and 3, the connecting parts in this embodiment are set to metal rolled band 3, and the shell 24 is fixed on the side of the metal rolled band 3 to the side of the tube 11. Take 3 bundles on the tube 11. In actual use, the operator can adjust the sound light alarm device 2 on the tube 11 according to the specific needs, or you can bundle multiple sound and light alarm on the same tube 11 on the same tube 11 The device 2 is used to perform sound and light early warning for multiple alarm values. Because the metal strip 3 is detachable, a single replacement can be performed when the sound and light alarm device 2 is damaged, reducing the replacement cost. In this embodiment, the metal rolling zone 3 can be set with a rubber layer for the side walls that are contacted with tube body 11. The metal rolling zone 3 is large. The outer surface of the scraping tube body 11, the setting of the rubber layer can effectively reduce the scraping phenomenon of the metal rolling zone 3 and the tube 11, and protect the tube body 11; at the same time 3 The friction between 11 and the tube body, avoid the phenomenon of self -weight on the tube 11 due to the decline in the tube 11, and the rubber layer has a certain elasticity, which can be tightly bundled on the metal rolling zone 3 buffer to a certain buffer. , can provide a reserved space for the deformation of the metal strip 3 or the pipe body 11 to a certain extent, and effectively reduce the damage probability of the pipe body 11 .

Example 2:

As shown in Figure 4, the difference between this embodiment and Embodiment 1 is that the connector is set as viscose or welding material, and the sound and light alarm device 2 is fixed on the pipe body 11 by gluing or welding. After the magnetic float 12 and the sound and light alarm device 2 are on the same horizontal plane, the sound and light alarm device 2 can send an alarm to remind the operator to make inspections.
