Abstract

The utility model discloses an overturning and water inflowing alarm detector, comprising a tilt detector, a tilt filter circuit, a water level detector, a water level filter circuit, an OR gate logic circuit, a drive circuit and a relay; wherein the tilt detector is connected with the tilt filter circuit, the water level detector is connected with the water level filter circuit, the tilt filter circuit and the water level filter circuit are respectively connected with the OR gate logic circuit, the OR gate logic circuit is connected with the drive circuit, and the relay is connected with the drive circuit. The overturning and water inflowing alarm detector of the utility model can simultaneously monitor the tilt and the water level, and can avoid misjudgements for a normal jitter or the water level; at the same time, the overturning and water inflowing alarm detector can be packaged in a small box, and the structure and the circuits of the detector are also simple, thus the detector has the advantages of low cost, small size, simpleness, practicability, and convenient manufacture; and the detector can timely cut off a power supply of an electric cabinet when an alarm occurs, thus an occurrence of a secondary injury accident that a person gets an electric shock can be prevented when an accidental tilt or the water inflowing occurs on the electric cabinet.

Description

Topple over and the water inlet Alarm Detector

Technical field

The utility model relates to a kind of regulator cubicle monitoring and protecting device, in particular a kind of topple over the water inlet Alarm Detector.

Background technology

Equipment such as regulator cubicle or charging pile operated by rotary motion is in public places particularly at the road periphery; Also be easy to have an accident except that artificial deliberately damage is and topple over (as being knocked down) or by water logging (like prominent chance torrential rain) by vehicle; The forceful electric power power supply that 220 volts or 380 volts are generally all arranged in the regulator cubicle, occurrence of tilting or power supply very easily causes the second accident that shocks by electricity and hurt sb.'s feelings in the cabinet as can not in time cutting off during by water logging.The regulator cubicle that is arranged on road periphery now generally all is placed in one and is higher than when being used to prevent heavy rain on the about 20 centimetres cement platform in road surface and has not just been had other safeguard procedures outside the water logging; Can face weather such as torrential rain in a lot of cities; During this weather the rainwater height through regular meeting above 20 centimetres; Since construction cost and problem such as attractive in appearance can not the anti-horizontal stand of unconfined increase height, this has caused great potential safety hazard to the urban development construction.

The utility model content

The utility model purpose: the purpose of the utility model is to overcome the deficiency of prior art, provides a kind of and has toppled over and the water inlet Alarm Detector, when accident is toppled over or intake, can cut off in the cabinet power supply while immediately and can in time cut off regulator cubicle and receive electric power supply.

Technical scheme: the utility model realizes that through following technical scheme the utility model comprises angle detection, slant filtering circuit, level switch, water level filter circuit or gate logic, drive circuit and relay; Wherein: angle detection links to each other with the slant filtering circuit; Level switch links to each other with the water level filter circuit; Slant filtering circuit and water level filter circuit respectively with or gate logic link to each other, or gate logic links to each other with drive circuit, relay links to each other with drive circuit.

Said angle detection comprises groove and ball, and ball is arranged in the groove, and ball is as an electrode; The two ends of groove are as another electrode; When detector tilted, when the angle of inclination was spent greater than 15, ball will roll the end to groove; Two electrodes send the alarm front end signal after connecting, this signal after the slant filtering circuit goes to tremble filtering with water level signal or.

Said level switch comprises two probes, and the length of two probes is different, when two probes touch water simultaneously, by the ionic conduction form circuit is connected and is sent the alarm front end signal, this signal after the water level filter circuit goes to tremble filtering with tilt signals or.

Beneficial effect: the utility model is compared prior art and had the following advantages: the utility model can be monitored inclination and water level simultaneously, can avoid misjudgment to normal shake or water level; Can product be encapsulated in the etui simultaneously, structure and circuit are fairly simple, have that cost is low, volume is little, simple and practical, easy to make; Can in time cut off the power supply of regulator cubicle when report to the police taking place, just can tilt because of accident or the situation of water inlet prevents the secondary injury accident generation that the personnel that cause get an electric shock when occurring at regulator cubicle.

Embodiment

Embodiment in the face of the utility model elaborates down; Present embodiment is being to implement under the prerequisite with the utility model technical scheme; Provided detailed execution mode and concrete operating process, but the protection range of the utility model is not limited to following embodiment.

As shown in Figure 1, the detector of present embodiment is installed in the charging pile, and this detector comprises angle detection 1, slant filtering circuit 2, level switch 3, water level filter circuit 4 or gate logic 5, drive circuit 6 and relay 7; Wherein: angle detection 1 links to each other with slant filtering circuit 2; Level switch 3 links to each other with water level filter circuit 4; Slant filtering circuit 2 and water level filter circuit 4 respectively with or gate logic 5 link to each other, or gate logic 5 links to each other with drive circuit 6, relay 7 links to each other with drive circuit 6.

As shown in Figure 2, angle detection 1 comprises groove 8 and ball 9, and ball 9 is arranged in the groove 8; Ball 9 is as an electrode, and the two ends of groove 8 are as another electrode, when detector tilts; When the angle of inclination was spent greater than 15, ball 9 will roll to the end of groove 8, sent the alarm front end signal after two electrodes are connected; This signal after slant filtering circuit 2 goes to tremble filtering with water level signal or, ball 9 is processed by steel ball in the present embodiment, is convenient to conduction.

As shown in Figure 3; Level switch 3 comprises two probes; First probe 10 and second probe 11 are processed by stainless steel, and first probe 10 is different with the length of second probe 11, has only when two probes touch water simultaneously; Circuit is connected send the alarm front end signal by the ionic conduction form, this signal after water level filter circuit 4 goes to tremble filtering with tilt signals or.

Tilt with any one alarm signal of water level through or gate logic 5 after all can produce an alarm signal; This signal is through the alarm signal of drive circuit 6 rear drive relays 7 generation dry contacts, and this alarm signal (single or two dry contacts) can be cut off the power supply (only needing control loop of reconfiguration to cut off the power supply of electrical equipment in the cabinet immediately for existing regulator cubicle) of electrical equipment in the charging pile immediately; And cut off the power supply that receives of this charging pile through the control of the existing communication network of charging pile, report to the police simultaneously and inform maintenance.

Can in time cut off the power supply of regulator cubicle when report to the police taking place, just can at charging pile or regulator cubicle tilts because of accident or the situation of water inlet prevents the secondary injury accident generation that the personnel that cause get an electric shock when occurring.
