The utility model discloses simple structure, convenient to use, sensitivity is high, and the degree of accuracy is high, and operating personnel need not to observe the interior dipstick of storage tank and transfers the condition during use, only need notice the alarm can, consequently avoided the emergence of operating personnel poisoning incident, safety ring protects.

Description

Portable manual scale

Technical Field

The utility model relates to a measuring tool, concretely relates to portable artifical chi of examining.

Background

At present, there are a lot of drawbacks in traditional artifical dipstick, when measuring oil level in the storage tank, operating personnel opens storage tank dipstick flap, the chi area is slow downwards along the dipstick groove, it stops the lower chi at once when fluctuating to observe the oil level, oil is stained with on the ruler when still noticing the lower chi, consequently operating personnel hardly avoids the dipstick mouth, the poor oil level of hardly observing of jar internal light is undulant, especially when the liquid level is few, it has poisonous harmful gas to volatilize to be close to dipstick mouth department, there is very big injury to the human body. When measuring the light oil level, it is difficult to determine whether the weight is in over-contact with the liquid level.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the shortcoming that prior art exists, provide a portable artifical scale.

In order to realize the purpose, the technical scheme of the utility model is that: the utility model provides a portable artifical scale which characterized in that: the magnetic float detection device comprises an alarm, a wire coil, a signal cable with a scale and a detection head, wherein the detection head comprises a magnetic float, a float guide pillar and a magnetic control switch, limiting rings are arranged at the upper end and the lower end of the float guide pillar, the float guide pillar is movably sleeved with the magnetic float, the inner diameter of the magnetic float is matched with the outer diameter of the float guide pillar, a cavity is formed in the center position of the float guide pillar close to the upper end, the magnetic control switch is arranged in the cavity, the magnetic control switch is connected with the signal cable with the scale, and the signal cable with the scale is connected.

Further, the method comprises the following steps of; the magnetic control switch is a reed switch.

Further, the method comprises the following steps of; the signal cable with the scale is a scale with 1mm precision arranged on the outer wall of the signal cable.

The utility model has the advantages that: the utility model discloses simple structure, convenient to use, sensitivity is high, and the degree of accuracy is high, and operating personnel need not to observe the interior dipstick of storage tank and transfers the condition during use, only need notice the alarm can, consequently avoided the emergence of operating personnel poisoning incident, safety ring protects.

FIG. 3 is a cross-sectional view of the probe when the magnetic float is not in contact with the liquid;

figure 4 is a cross-sectional view of the probe after the magnetic float has floated above the liquid surface.

In the figure: 1. an alarm; 2. wire coils; 3. a signal cable with a scale; 4. a probe head; 5. a magnetic float; 6. a float guide post; 7. a reed switch; 8. a limiting ring; 9. a cavity.

Detailed Description

Example (b):

as shown in fig. 1 and 2, the portable manual scale comprises an alarm 1, a wire coil 2, a signal cable 3 with a scale and a detection head 4, wherein the detection head 4 comprises a magnetic floater 5, a floater guide post 6 and a reed switch 7, limiting rings 8 are arranged at the upper end and the lower end of the floater guide post 6, the floater guide post 6 is movably sleeved on the magnetic floater 5, the inner diameter of the magnetic floater 5 is matched with the outer diameter of the floater guide post 6, the outer diameter of the limiting rings 8 is larger than the inner diameter of the magnetic floater 5, a cavity 9 is arranged at the central position of the floater guide post 6 close to the upper end, the reed switch 7 is arranged in the cavity 9, the signal cable 3 with the scale is respectively connected to the two opposite ends of the reed switch 7, and the signal cable 3 with the scale passes through the limiting rings 8 at the upper end of the floater guide post 6. The signal cable 3 with the scale is a scale with 1mm precision arranged on the outer wall of the signal cable.

During the use, will only need to transfer into the jar with detecting head 4, operating personnel observes alarm 1 can. When the magnetic floater 5 is not in contact with the liquid surface, the distance between the reed switch 7 and the magnetic floater 5 is far away from the magnetic floater 5 and is not influenced by the magnetic floater 5, and the reed switch is in a disconnected state (as shown in fig. 3); when the magnetic floater 5 is contacted with the liquid level to float upwards, the reed switch 7 is influenced by the magnetic floater 5 and is switched to be in a closed state (as shown in figure 4), the circuit is conducted, the alarm 1 gives an alarm, and at the moment, the operator records corresponding liquid level data on the signal cable 3 with the scale.

The above-described embodiments are merely preferred and are not intended to limit the present invention in any way, and other variations and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.

In the description of the present invention, it is to be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, and do not indicate or imply that the equipment or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
