When the pipeline pressure of the natural gas pipeline corresponding to a certain gas pressure adjusting device 30 is abnormal, the server terminal 60 displays the current corresponding gas pressure adjusting device 30 in real time, and the operation center dispatches a technician to timely and accurately arrive at the site for treatment.
According to the operation specification of safety rules, two workers need to be present at the same time during detection and maintenance; however, in the actual operation process, the maintenance is often performed by only one worker. The situation is not in accordance with the operation specification, potential safety hazards exist, and safety accidents are easily caused. Therefore, how to upgrade and reform the structure of the protective equipment 34 realizes that the pressure can be regulated only under the condition that two workers are on the spot at the same time, and further improves the safety of the pressure regulating system.
Specifically, as shown in fig. 3 and 4, the protection device 34 includes: the first door 100, the second door 200 and the cabinet body 300, and the first door 100 and the second door 200 cover the cabinet body 300. It can be seen that the shielding device 30 is a double door structure.
As shown in fig. 5, a first elastic lock set is disposed on the first door 100, the first elastic lock set includes a first gear 110 and a first lock pin 120, a return elastic member 101 is disposed between the first lock pin 120 and the first door 100, the first gear 110 drives the first lock pin 120 to slide on the first door 100, and a first lock slot 130 engaged with the first lock pin 120 is disposed on the second door 200. Preferably, the first latch 120 is provided with a rack, the first gear 110 is engaged with the first latch 120, and the rotation of the first gear 110 can cause the first latch 120 to slide, so that the first latch 120 can slide into the first latch slot 130, and the first door 100 and the second door 200 can be locked together.
Further, as shown in fig. 5, a second elastic lock group is disposed on the second door 200, and the structure of the second elastic lock group is similar to that of the first elastic lock group, specifically, the second elastic lock group includes a second gear 210 and a second lock pin 220, a return elastic member 101 is disposed between the second lock pin 220 and the second door 200, the second gear 210 drives the second lock pin 220 to slide on the second door 200, and a second lock groove 230 engaged with the second lock pin 220 is disposed on the first door 100. Similarly, the second lock pin 220 is engaged with the second gear 210, and the rotation of the second gear 210 may cause the second lock pin 220 to slide, and cause the second lock pin 220 to cooperate with the second lock groove 230, so as to lock the first door 100 and the second door 200 together.
Preferably, the first gear 110 and the second gear 210 are both provided with a rotating handle 102 (as shown in fig. 3) for facilitating the operation of the worker.
It should be noted that the first gear 110 and the second gear 210 are respectively disposed on the first door 100 and the second door 200, and the first gear 110 is located at the end of the first lock pin 120, and the second door 200 is located at the end of the second lock pin 220, so that the distance between the first gear 110 and the second gear 210 is intentionally increased, and two workers are required to cooperate with each other to unlock the lock. The specific operation is as follows:
when the lock is unlocked, a worker rotates the rotating handle 102 of the first gear 110, and since the first gear 110 is meshed with the first lock pin 120, the rotation of the first gear 110 drives the first lock pin 120 to slide, and at the moment, the reset elastic element 101 on the first lock pin 120 is compressed; as the first lock pin 120 slides, the first lock pin 120 will finally disengage from the first lock slot 130, so that the first lock pin 120 no longer connects the first door 100 and the second door 200, and primary unlocking is achieved;
due to the return elastic member 101, the worker cannot release his hand after rotating the first gear 110, otherwise the first lock pin 120 will be locked again in the first lock groove 130 by the return elastic member 101, and thus the worker cannot release his hand at this moment. Meanwhile, the distance between the first gear 110 and the second gear 210 is relatively long, so that the worker cannot touch the rotating handle 102 of the second gear 210 without loosing hands, and thus the worker cannot open the protection device 34 by himself or herself and needs the assistance of another worker;
similarly, another worker rotates the rotating handle 102 of the second gear 210 to make the second gear 210 drive the second lock pin 220 to slide, so that the second lock pin 220 overcomes the elastic force of the reset elastic member 101 and is separated from the second lock groove 230 to realize secondary unlocking. Thus, the first door 100 and the second door 200 can be opened by two workers, so that the pressure regulating device 33 therein can be maintained.
Further, it is considered that the pressure regulating device 33 needs to be effectively protected in actual use to prevent an irrelevant person from opening the protecting device 34 and operating the pressure regulating device 33 at will. Therefore, in the present invention, the security apparatus 34 further includes a security lock device 400 (as shown in fig. 5), and the security lock device 400 is mounted on the first door 100, and the security lock device 400 serves as a first safeguard of the security apparatus 30, and the first lock pin 120 cannot be disengaged from the first lock slot 130 without unlocking the security lock device 400.
The following describes the structure of the security lock device 400 in detail with reference to the present embodiment:
as shown in fig. 6, the security lock arrangement 400 comprises: the lock assembly 410, a rotating rod 420, a base 430, a bottom movable member 440 and a wrench 450 movably connected with the base 430. The lock set 410 is provided with a key 411 matched with the lock set 410, the rotating rod 420 is in driving connection with the lock set 410, and the lock set 410 can be rotated only when the matched key 411 is inserted into the lock set 410, so that the rotating rod 420 is driven to rotate;
as shown in fig. 6, the base 430 is mounted on the first door 100, the base 430 is provided with a receiving through groove 431, the wrench 450 is movably inserted into the receiving through groove 431, the bottom movable member 440 is disposed below the receiving through groove 431 through the telescopic elastic member 441, the wrench 450 presses or disengages the bottom movable member 440, and the bottom movable member 440 is provided with a blocking piece 442. The first lock pin 120 is provided with an anti-falling limiting part 121, and the anti-falling limiting part 121 abuts against or is separated from the rotating rod 420.
It is noted that the wrench 450 is used to operate the pressure adjusting device 33, and is an essential tool for maintenance. In the embodiment, the wrench 450 is movably inserted into the receiving through groove 431, and when the wrench is used, a worker takes out the wrench 450 from the receiving through groove 431; after maintenance, the worker replaces the wrench 450 in the accommodating groove 431. Therefore, the maintenance of the working personnel does not need to additionally carry an operation tool, so that the convenience is brought to the working personnel, and the condition of lack of tools during the maintenance is also avoided.
The following explains the working principle of the security lock device 400 with reference to the above structure, and please refer to fig. 6 to 9 together:
initially, the security lock device 400 is in a locked state, the lock set 410 cannot rotate, and the first lock pin 120 is locked in the first lock slot 130. At this time, if the worker rotates the first gear 110 to try to unlock, the first lock pin 120 slides, and the anti-falling limiting part 121 and the rotating rod 420 are clamped together, so that the first lock pin 120 is prevented from continuously sliding, and the first lock pin 120 cannot be separated from the first lock groove 130, that is, the first elastic lock group cannot be unlocked at this time;
when unlocking, firstly, the key 411 is inserted into the lock set 410, so that the lock set 410 can be rotated, and then the key 411 can drive the rotating rod 420 to rotate. The rotating rod 420 is rotated to a certain angle towards the side away from the wrench 450 (counterclockwise as shown in fig. 7), at this time, the rotating rod 420 is no longer on the movement track of the anti-drop limiting part 121, and the safety lock device 400 is in the unlocked state. In the unlocking state, when the worker rotates the first gear 110, the first lock pin 120 slides along with the first gear, the anti-falling limiting part 121 is not blocked by the rotating rod 420, and the first lock pin 120 can be smoothly separated from the first lock groove 130, so that unlocking is realized. Then two workers can operate as described above to open the first door 100 and the second door 200;
during maintenance, the worker takes out the wrench 450 from the accommodating through groove 431 to operate the valve of the pressure regulating device 33. As shown in fig. 8, when the wrench 450 is removed, the wrench 450 is no longer pressed against the bottom-supporting movable member 440, and the bottom-supporting movable member 440 starts to slide upward under the elastic force of the elastic member 441, so that the blocking piece 442 abuts against the groove wall of the receiving through groove 431. If the safety lock device 400 is locked, the rotating rod 420 needs to be reset below the containing through groove 431; however, the rotating rod 420 cannot be completely reset due to the blocking of the blocking piece 442, and thus the key 411 cannot be pulled out of the lock set 410;
after maintenance, the worker replaces the wrench 450 to the accommodating groove 431, the bottom-supporting movable member 440 is pressed by the wrench 450 again, the telescopic elastic member 441 is compressed, the bottom-supporting movable member 440 descends, and the blocking piece 442 is far away from the accommodating groove 431. Then, the worker closes the first door 100 and the second door 200 to lock the first latch 120 and the second latch 220, and then rotates the rotating rod 420 to be completely restored below the receiving groove 431. Thus, the key 411 can be pulled out from the lock set 410, and the lock set 410 and the rotating rod 420 cannot rotate after being pulled out.
It is emphasized that the safety lock arrangement 400 of the present invention has the following features: first, only after unlocking the safety lock device 400, the first lock pin 120 can be disengaged from the first lock groove 130, and the safety lock device 400 can be unlocked only by using the matched key 411, so that the safety of the protection device 30 is improved; secondly, only after the wrench 450 is replaced into the accommodating through groove 431, the safety lock device 400 can be locked again, and the key 411 can be pulled out, so that the worker can be reminded to return the wrench 450, and the wrench 450 is prevented from being taken away.
In one embodiment, as shown in fig. 9, the base 430 is further provided with a limiting groove 432, and the bottom-supporting movable member 440 is slidably disposed in the limiting groove 432, so that the bottom-supporting movable member 440 can be prevented from being dislocated in the lifting process.
