Description

Technical Field

[0001] This utility model relates to the field of cable level gauge technology, and in particular to a cable level gauge. Background Technology

[0002] A cable level gauge is a continuous liquid level measuring device based on mechanical principles. It measures the displacement of a weight or float suspended inside a container as the liquid level changes, and converts this displacement into an electrical signal output. Its core feature is the use of a corrosion-resistant cable to connect the measuring probe to the signal processing unit, enabling non-contact measurement. However, cable level gauges require the probe to be immersed in the liquid for use. Existing devices require manual adjustment of the cable length, resulting in a relatively poor user experience. Furthermore, prolonged exposure to the external environment can easily damage the device, shortening its lifespan. Utility Model Content

[0003] This invention proposes a cable-type liquid level gauge to solve the problem of inconvenient adjustment of the external length of existing devices.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a cable-type liquid level gauge, comprising a protective component and a measuring component for measuring liquid level, wherein the measuring component comprises a liquid level gauge body, a cable and a stainless steel probe, the cable is fixedly connected between the stainless steel probe and the liquid level gauge body, and an electrical interface is fixedly connected to one side of the stainless steel probe; the protective component is recessed to form a protective cavity for accommodating the liquid level gauge body, and the bottom of the liquid level gauge body is fixedly connected to the bottom end of the protective cavity.

[0005] A connector is installed on the cable. A clip is fixedly connected to the top of the connector. The bottom of the protective component is recessed to form a slot and a socket. The socket communicates with the slot, and both the slot and the socket match the clip.

[0006] Preferably, the connector includes a connecting plate, a connecting pipe is fixedly connected to the bottom of the connecting plate, and a connecting hole for the cable to pass through is formed between the connecting plate and the connecting pipe. A movable screw is screwed onto one side of the connecting pipe, and the free end of the screw extends into the interior of the connecting hole to abut the cable.

[0007] Preferably, the peripheral surface of the connecting plate is recessed to form a notch or groove.

[0008] Preferably, the protective component includes a base, and the slot and the insertion hole are formed on the bottom of the base.

[0009] Preferably, a connecting ring is fixedly connected to the top of the base, and a detachable protective shell is screwed onto the top of the connecting ring. The protective cavity is formed at the bottom of the protective shell, and a handle is fixedly connected to the top of the protective shell.

[0010] Preferably, nylon ropes are bonded to both sides of the circumference of the base.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0012] (1) By setting up connectors and protective components, when it is necessary to adjust the outward length of the cable, the connectors support the clamps and the connectors are fixed above the protective components by the notches on the connectors. The protective components cover the cable, so that the cable length can be easily adjusted when the device is measuring, without the need for manual bundling, thus improving the user experience.

[0013] (2) This utility model sets up a protective shell and a connecting ring, supports the connecting ring with the base, and connects the protective shell with the connecting ring by screwing them together, so that the protective shell is fixed on the connecting ring. The protective cavity on the protective shell protects the liquid level gauge body, avoids the device from being exposed to the external environment for a long time, reduces the probability of damage to the device, and extends the service life of the liquid level gauge.

[0024] like Figures 1-7 As shown, a cable level gauge includes a protective component 1 and a measuring component 2 for measuring liquid level. The measuring component 2 includes a level gauge body 21, a cable 23 and a stainless steel probe 24. The cable 23 is fixedly connected between the stainless steel probe 24 and the level gauge body 21. An electrical interface 22 is fixedly connected to one side of the stainless steel probe 24. The protective component 1 is recessed to form a protective cavity 18 to accommodate the level gauge body 21. The bottom of the level gauge body 21 is fixedly connected to the bottom end of the protective cavity 18.

[0025] A connector 3 is installed on the cable 23. The top of the connector 3 protrudes outward and is fixedly connected to a clip 33. The bottom of the protective part 1 is recessed to form a slot 16 and a socket 17. The socket 17 communicates with the slot 16, and both the slot 16 and the socket 17 are matched with the clip 33.

[0026] With the above technical solution, when using the device, if it is necessary to adjust the exposed length of the cable 23, pull the connector 3 to move the cable 23 until the clip 33 on the connector 3 engages with the insertion hole 17 at the bottom of the protective component 1. Then rotate the connector 3 to engage the clip 33 on the connector 3 with the slot 16, thus completing the connection between the connector 3 and the protective component 1, thereby shortening the exposed length of the cable 23. After adjusting the exposed length of the cable 23, place the cable 23 and the stainless steel probe 24 in the liquid to be measured. The liquid level is detected by the operation of the stainless steel probe 24 and the cable 23.

[0027] Specifically, in one embodiment, regarding the aforementioned connector 3, as...

A movable screw 36 is screwed onto one side of the connecting pipe 34, and the free end of the screw 36 extends into the interior of the connecting hole 35 to abut against the cable 23.

[0028] In this embodiment, when it is necessary to store the cable 23, pull the connecting plate 31 so that the connecting plate 31 drives the connecting tube 34 to move along the cable 23. After the connecting plate 31 moves to the required position, rotate the screw 36 on the connecting tube 34 so that the screw 36 abuts against the cable 23 in the connecting hole 35, so that the connecting plate 31 is fixed in the required position. Then, engage the clip 33 on the connecting plate 31 with the slot 16 at the bottom of the protective component 1.

[0029] When winding up cable 23, in order to facilitate the arrangement of cable 23, such as Figures 6-7 As shown, the circumferential surface of the connecting plate 31 is recessed to form a notch 32.

[0030] In this embodiment, after the connecting plate 31 and the base 14 are fixedly connected, the cable 23 is made easy to organize by the notch 32.

[0031] Specifically, in one embodiment, regarding the aforementioned protective element 1, as... Figures 1-4 As shown, the protective component 1 includes a base 14, a slot 16 and an insertion hole 17 formed on the bottom of the base 14.

[0032] To protect the level gauge body 21, such as Figures 1-4 As shown, a connecting ring 13 is fixedly connected to the top of the base 14, and a detachable protective shell 11 is screwed onto the top of the connecting ring 13. A protective cavity 18 is formed at the bottom of the protective shell 11, and a handle 12 is fixedly connected to the top of the protective shell 11.
