Fig. 2 is that the installation of other a kind of embodiment of the pipeline compensator safety monitoring autoalarm that proposes of the utility model concerns synoptic diagram.
Embodiment
Describe in detail below in conjunction with the embodiment of accompanying drawing the utility model.
Embodiment one; Present embodiment is in order to guarantee pipeline safety; Designed a kind of be used for monitoring the pipeline compensator whether safe operation and the safety feature of when touching the hazardous location, reporting to the police automatically, mainly comprised ingredients such as pointer 1, detector switch 2 and alarm mechanism 3, referring to shown in Figure 1.Wherein, pointer 1 is installed on the movable end 5 of pipeline compensator, together moves with movable end 5, is used to indicate the current run location of movable end 5.Detector switch 2 specifically can adopt limit switch or travel switch etc.; Its mounting means can adopt various ways; As long as satisfy when the movable end 5 of pipeline compensator runs to maximum safe operation position; Can be touched by pointer 1, and then control connected alarm mechanism 3 and start to report to the police and get final product.
As a kind of preferred design of present embodiment, the installation site of said detector switch 2 preferably is positioned at the maximum safe operation position of the movable end 5 of pipeline compensator, specifically can be installed on the detection ruler 4, and is as shown in Figure 1.One end of said detection ruler 4 is fixed on the stiff end 6 of pipeline compensator, and an other end extends in parallel to the direction of motion of movable end 5 away from stiff end 6, and promptly the length direction of detection ruler 4 should parallel with the traffic direction of the movable end 5 of pipeline compensator.In order to make the monitoring personnel can be well understood to the current operation conditions of pipeline compensator movable end 5; Be that run location is still to be in the scope of safety zone; Still prewarning area even hazardous location have been got into; Present embodiment preferably is provided with different marked areas on said detection ruler 4, safe operation for example shown in Figure 1 zone A, prewarning area B and hazardous location C etc. specifically can adopt different colors to be plotted on the lateral surface of detection ruler 4 and show the each several part zone.Wherein, the separatrix of safe operation zone A and prewarning area B promptly may be defined as the maximum safe operation position of the movable end 5 of pipeline compensator, detector switch 2 promptly be installed on the described detection ruler 4 and with corresponding position, described separatrix.
In order specifically, clearly to indicate the current run location of pipeline compensator movable end 5, present embodiment is preferably set up the scale mark 8 that is used for gauge length on said detection ruler 4, promptly form scale.Utilize pointer 1 to point to scale mark 8, the monitoring personnel can clearly grasp pipeline compensator movable end 5 current concrete displacements.
Said pointer 1 can be positioned at the top or the below (as shown in Figure 1) of detection ruler 4, also can pass detection ruler 4, in the middle of detection ruler 4, move (as shown in Figure 2), and present embodiment preferably adopts a kind of design proposal in back.As shown in Figure 2; Present embodiment can (preferred centre position) be offered a pointer orbit 7 along the length direction penetration-detection chi 4 of detection ruler on detection ruler 4; Said pointer 1 is positioned at the outside of detection ruler 4, passes on the movable end 5 that described pointer orbit 7 is fixedly mounted on pipeline compensator through fixed leg.When the movable end 5 of pipeline compensator moves, drive pointer 1 and move, with movable end 5 current zone and the concrete displacements that run to that clearly indicate pipeline compensator along described pointer orbit 7.
In order to make detector switch 2 after being touched by pointer 1; Can control alarm mechanism 3 in time and start warning; Present embodiment is connected the armature contact of detector switch 2 in the current supply circuit of alarm mechanism; Through the action of detector switch 2 armature contacts, be communicated with the connecting path of alarm mechanism 3 and power supply, and then electric alarm on the control alarm mechanism 3.
For the connected mode of detector switch 2 with alarm mechanism 3; Present embodiment has proposed two kinds of concrete design proposals here: a kind of is direct often opening in the connection line that armature contact is connected on alarm mechanism 3 and power supply detector switch 2; When detector switch 2 is touched by pointer 1; Closed its often opened armature contact, and then alarm mechanism 3 is communicated with power supply, and control alarm mechanism 3 electrifying startups are reported to the police.Use the alarm mechanism of Alternating Current Power Supply for needs; Then can be at first often opening in the current supply circuit that armature contact is connected on an ac contactor coil said detector switch 2; Normally opened contact with said A.C. contactor is connected in the connection line of alarm mechanism and AC power then; When detector switch 2 was touched by pointer 1, closed its often opened armature contact, and then makes the coil electricity of A.C. contactor; The normally opened contact of adhesive A.C. contactor can power on alarm mechanism 3 and starts output alarm.
Certainly, utilize the mode of the action control alarm mechanism startup warning of said detector switch 2 to also have a variety of design proposals, present embodiment is not limited in above giving an example.
In the present embodiment, the said alarm mechanism 3 preferred audible-visual annunciators that adopt utilize the form of sound and light alarm to remind the monitoring personnel in time pipeline compensator to be detected, to avoid the generation of peril.
The autoalarm that present embodiment proposed can be applied in the pressure pipeline compensator, also can be applied in the heat supply pipeline compensator.Because it can accomplish round-the-clock running without interruption under unmanned situation for intervention, therefore, eliminated the monitoring blind area, has guaranteed the safe operation of pipelines such as crude oil or heat supply.
Certainly; The above only is a kind of preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
