Description of drawings
The structural representation of the gas pump termination of pumping autoalarm that Fig. 1 provides for one embodiment of the invention.
The structural representation of the high pressure vacuum magnetic starter that Fig. 2 provides for one embodiment of the invention.
Embodiment
For the purpose, technological scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technological scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiments.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making all other embodiments that obtained under the creative work prerequisite.
The embodiment of the invention provides a kind of gas pump termination of pumping autoalarm, by in the extraction equipment of gas pump, warning device being set, to prevent out of service and unmanned supervision because of cause specific gas pump, cause the gas pump shutdown to find to lag behind, handle problems such as untimely.
Referring to the structural representation that Figure 1 shows that gas pump termination of pumping autoalarm, this device comprises: switch module 11, control module 12 and alarm module 13.
The device of present embodiment, switch module 11 comprises normally opened contact and normally-closed contact, normally opened contact and normally-closed contact are not closed simultaneously.Normally opened contact is connected with the gas pump, and when control module 12 detected gas pump proper functioning, the adhesive normally opened contact kept the normally opened contact closure, makes the circuit turn-on of gas pump, and the control normally-closed contact disconnects; When control module 12 detects the gas pump when out of service, the control normally opened contact disconnects, keep the circuit of gas pump to disconnect, and the adhesive normally-closed contact, the circuit turn-on of the alarm module 13 that link to each other with normally-closed contact this moment, report to the police, gas pump out of service is in time handled for the pumping plant driver.
Therefore, by above-mentioned gas pump termination of pumping autoalarm as can be known, by normally opened contact and normally-closed contact are set, and the circuit interlock of normally opened contact and normally-closed contact, can connect an alarm module 13 at normally-closed contact place circuit thus, when the gas pump shutdown, can report to the police by alarm module 13, prompting pumping plant driver carries out respective handling, the Security when having guaranteed the gas pump shutdown thus.Wherein, alarm module 13 comprises a power supply, an acousto-optic composite signal device and an audible-visual annunciator, and this power supply is used to alarm module 13 power supplies, acousto-optic composite signal device to be used for the guide sound light crossing-signal and to send the acoustooptic alarm signal.
In addition, can also establish a control switch in addition at alarm module 13, with the work of control alarm module 13, when this switch disconnected, alarm module 13 was not worked, even the normally closed switch closure, alarm module 13 is not reported to the police yet.When this switch on, alarm module 13 just can be reported to the police after the normally closed switch closure.
For ease of specific implementation, in the present embodiment, the switch module of this gas pump termination of pumping autoalarm can adopt a high pressure vacuum magnetic starter, is illustrated in figure 2 as the structural representation of high pressure vacuum magnetic starter.In the present embodiment, can specifically adopt QBG-250/6 type high pressure vacuum magnetic starter.
QBG-250/6 type high pressure vacuum magnetic starter comprises 5 groups of contacts, and wherein, normally opened contact is 2 groups, and normally-closed contact is 3 groups, and as shown in Figure 2, in 10 contacts of this device, contact 1 and contact 2 are one group, and contact 3 and contact 4 are one group, as two groups of normally opened contacts; Contact 5 and contact 6 are one group, and contact 7 and contact 8 are one group, and contact 9 and contact 10 are one group, as three groups of normally-closed contacts.Wherein normally opened contact is connected with the gas pump, and normally-closed contact links to each other with alarm module.
This high pressure vacuum magnetic starter connects a controller BC, the disconnection and the closure of control normally opened contact and normally-closed contact, and when gas pump proper functioning, this controller BC adhesive normally opened contact, control normally opened contact closure, normally-closed contact disconnects; When the gas pump shutdown, this controller BC adhesive normally-closed contact, control normally-closed contact closure, normally opened contact disconnects.
Referring to shown in Figure 2, one group in the normally closed switch in alarm module and this high pressure vacuum magnetic starter is connected, as being connected with 10 with normally-closed contact 9 according to shown in Figure 2.Alarm module comprises a power supply, as being the power supply of the 127V among the figure; An one acousto-optic composite signal device BS and an audible-visual annunciator BE.
In this high pressure vacuum magnetic starter, normally-closed contact 5 and 6 and normally-closed contact 7 and 8 idle, but can be used as the expansion contact further expands and connects the module that goes up other.As adding a display modular (not shown), when the gas pump is out of service, connect the circuit of this display modular, start the state that this display modular shows the gas pump.Should can be used for gas pump termination of pumping autoalarm is carried out further function expansion in idle contact.
The gas pump termination of pumping autoalarm of the embodiment of the invention, have simple in structure, the characteristics that using effect is good, when the gas pump shutdown, in time alert notice pumping plant driver safeguards accordingly, make the pumping plant driver to detect the gas pump and whether stop transport, reduced staff's labor intensity, guaranteed the safe and reliable operation of gas pumping system by platform.
