Abstract

A circulating water shortage alarming system for an air compressor comprises a base, a balance plate, a support pillar, a tension spring, a first electric contact point, a second electric contact point, an alarming device, a power supply and a water reservoir; the water reservoir is provided with a water inlet and a water outlet; the support pillar is vertically arranged on the base; the two ends of the balance plate are propped on the support pillar; the water reservoir is arranged at the first end of the balance plate; the water inlet of the water reservoir is communicated with a circulating water drainage pipe of the air compressor; the flow rate of the water outlet of the water reservoir is less than that of the water inlet; the tension spring is arranged between the second end of the balance plate and the base; when the water reservoir is full of water, the two ends of the balance plate are counterbalanced under the actions of the pulling force of the tension spring and the gravity of the water reservoir; the first electric contact point is arranged at the second end of the balance plate; the second electric contact point is arranged in the corresponding contact position of the first electric contact point when the second end of the balance plate inclines downwards; and the power supply and the alarming device are connected between the first and the second electric contact points in series. If the air compressor has a shortage of water, the pulling force of the tension spring is greater than the gravity of the water reservoir, and the two electric contact points are in contact with each other, so that the alarming device is turned or and gives an alarm.

Description

A kind of air compressor circulating water lack of water alarm system

Technical field

The utility model relates to the air compressor technical field in the mining industry production, relates in particular to a kind of air compressor circulating water lack of water alarm system.

Background technique

At present, air compressor circulating water is mainly used in to air compressor cooling, can cause operating valve to catch fire, be stained with cylinder during lack of water, can make when serious complete machine scrap in addition pipeline in oil smoke is discharged to working surface behind the Waste-oil combustion, cause the serious personnel casualty accident of suffocating.Take place in order to reduce such accident,, invented a kind of air compressor circulating water lack of water alarm system through repeatedly practice.

The model utility content

The purpose of this utility model provides a kind of air compressor circulating water lack of water alarm system.

A kind of air compressor circulating water lack of water alarm system, wherein: comprise base, balance plate, supporting post, extension spring, first, second electrical pickoff, warning device, power supply and wet pit, wet pit is provided with water intake and water outlet, supporting post is erected on the base, balance plate two ends balanced support is on supporting post, wet pit is arranged on first end of balance plate, the water intake of wet pit is used to be communicated with the circulating water waste pipe of air compressor, the water outlet flow of wet pit is less than the flow of water intake, extension spring is arranged between balance plate second end and the base, and when wet pit was filled water, the pulling force of extension spring and the gravity of wet pit made balance plate two ends balance; Second end of balance plate is provided with first electrical pickoff, and second electrical pickoff is arranged at the contact position of balance plate second end first electrical pickoff correspondence when downward-sloping, serial connection power supply and warning device between first, second electrical pickoff.

Described air compressor circulating water lack of water alarm system, wherein: described warning device comprises electric bell.

Described air compressor circulating water lack of water alarm system, wherein: described warning device comprises LED light emitting deivce.

The utility model adopts technique scheme will reach following technique effect:

Air compressor circulating water lack of water alarm system of the present utility model, utilize the principle of balance, balance plate two ends balanced support is on supporting post, wet pit is arranged on first end of balance plate, extension spring is arranged between balance plate second end and the base, when wet pit is filled water, the pulling force of extension spring and the gravity of wet pit make balance plate two ends balance, because of wet pit continuously in draining, if during the air compressor lack of water, water inlet in the wet pit reduces or does not have, and the water in the wet pit will reduce, and the pulling force of extension spring is during greater than current wet pit weight, second end at the extension spring place of balance plate is with downward-sloping, first electrical pickoff of the balance plate second end setting and the corresponding contact of second electrical pickoff that is arranged at the balance plate second end bottom, first, serial connection power supply and warning device constitute the loop between second electrical pickoff, and warning device gets electric enforcement and reports to the police.As fully visible, air compressor circulating water lack of water alarm system of the present utility model can be implemented to report to the police when air compressor circulating water lack of water.

Description of drawings

Fig. 1 is the structure principle chart of air compressor circulating water lack of water alarm system of the present utility model.

Embodiment

A kind of air compressor circulating water lack of water alarm system, as shown in Figure 1, comprise base 7, balance plate 11, supporting post 6, extension spring 5, first electrical pickoff 3, second electrical pickoff 4, electric bell 2, power supply 1 and wet pit 9, wet pit 9 is provided with intake pipe 8 and outlet pipe 10, supporting post 6 is erected on the base 7, balance plate 11 two ends balanced support are on supporting post 6, wet pit 9 is arranged on first end of balance plate 11, the intake pipe 8 of wet pit is used to be communicated with the circulating water waste pipe of air compressor, outlet pipe 10 flows of wet pit 9 are less than the flow of intake pipe 8, the two ends of extension spring 5 are separately fixed at balance plate 11 second end downsides, above the base 7, the gravity of wet pit 9 makes balance plate two ends balance when setting in advance the pulling force of extension spring 5 and filling water; Second end of balance plate is provided with the contact position that first electrical pickoff, 3, the second electrical pickofves 4 are arranged at balance plate second end first electrical pickoff correspondence when downward-sloping, serial connection power supply and warning device between first, second electrical pickoff; When the pulling force of extension spring 5 gravity of wet pit 9 when filling water made balance plate 11 two ends balances, first electrical pickoff, 3, the second electrical pickofves 4 did not contact; Because of wet pit 9 continuously in draining, if during the air compressor lack of water, water inlet in the wet pit 9 reduces or does not have, water in the wet pit 9 will reduce, wet pit 9 weight reduce, the pulling force of extension spring 5 is during greater than current wet pit 9 weight, balance plate 11 second ends at extension spring 5 places are with downward-sloping, first electrical pickoff 3 of balance plate 11 second end settings and second electrical pickoff, the 4 corresponding contacts that are arranged at balance plate 11 second end bottoms, the power supply 1 of serial connection and electric bell 2 constitute the loop between first, second
