[0031] Figure 1 and Figure 2 The air source lock 10 in some embodiments of the utility model is shown. The air source lock 10 is used to protectively lock the air source connector when necessary to avoid misoperation of the air source connector and improve the safety factor of operation.

[0032] The air source lock 10 includes a covering device 1 and a locking device 2. The covering device 1 can be detachably covered on the air source connector. The locking device 2 is used to lock the covering device 1 when needed, so that the covering device 1 maintains protective covering on the air source connector.

[0033] like Figures 1 to 4 As shown, the covering device 1 includes a movable connection component 11 and a plurality of protection seats 12, and each protection seat 12 is connected to the movable connection component 11; the locking device 2 includes a detachable locking member 21 and a plurality of locking positions 22, and each locking position 22 is correspondingly arranged on each protection seat 12.

[0034] It can be understood that the arrangement of the movable connection assembly 11 enables each protection seat 12 to be movable. Each protection seat 12 can be folded and enclosed into a cylindrical shape, so as to be sleeved and fixed on the air source connector. The locking position 22 is used for the detachable locking member 21 to be inserted and fixed.

[0035] At least part of the protection seat 12 is configured to be movable through the movable connection component 11, so that each protection seat 12 can be closed and fixed outside the air source connector 30, and each locking position 22 is aligned; the detachable locking piece 21 is configured to be able to penetrate and fix each locking position 22, thereby limiting the relative position of each protection seat 12.

[0036] It can be understood that the number of protection seats 12 can be flexibly set; when the number of protection seats 12 is configured as multiple, some of the protection seats 12 can be configured to be movable through the movable connection component 11, or all of the protection seats 12 can be configured to be movable through the movable connection component 11, and it is only necessary to ensure that each protection seat 12 can be closed and retracted outside the air source joint. The movable modes of each protection seat 12 can be the same or different, and some of the protection seats 12 can be configured to slide in a predetermined direction, while the remaining protection seats 12 can be configured to rotate. Of course, all of the protection seats 12 can also be configured to slide or rotate.

[0037] It should be noted that when each protective seat 12 is not connected and locked by the detachable locking piece 21, it can be changed into various positions within the normal range of movement; after each protective seat 12 is folded and merged onto the gas source connector, the locking positions 22 on each protective seat 12 will be aligned. At this time, after the detachable locking piece 21 is passed through each locking position 22 for fixing, the relative position of each locking position 22 can be fixed or limited, that is, the purpose of limiting the relative position of each protective seat 12 is achieved, thereby preventing the protective seat 12 from falling off the gas source connector, thereby achieving the purpose of protectively covering the gas source connector.

[0038] It should also be noted that the outer contour of each protective seat 12 can be flexibly set. Specifically, after the protective seats 12 are combined and locked by the detachable locking piece 21, they can be firmly mounted on the outside of the air source connector. That is, the protective covering of the air source connector by each protective seat 12 can only be released after the detachable locking piece 21 is removed.

[0039] like Figures 1 to 4 As shown, in some embodiments of the air source lock 10, each protection seat 12 is provided with a first avoidance groove 121 and a second avoidance groove 122, and each first avoidance groove 121 is configured to define a first avoidance hole 1211 when each protection seat 12 is closed and retracted (the first avoidance hole 1211 is shown in FIG. Figure 4), each second avoidance groove 122 is configured to jointly define a second avoidance hole 1221 when each protection seat 12 is closed and retracted; wherein, the first avoidance hole 1211 is connected to the second avoidance hole 1221, and the air source connector 30 is located between the first avoidance hole 1211 and the second avoidance hole 1221.

[0040] It can be understood that each first avoidance groove 121 is used to avoid the pipe body, pipeline or pipeline of the gas source connector 30, and the second avoidance groove 122 is used to avoid the pipeline, pipeline or pipe body from the outside to the gas source connector 30. The first avoidance hole 1211 and the second avoidance hole 1221 are connected to each other.

[0041] It should be noted that in actual use, each protective seat 12 is placed outside the air source connector 30, and after each locking position 22 is locked by a detachable locking piece 21, each first avoidance groove 121 is placed around one end of the air source connector 30, and each second avoidance groove 122 is placed around the other end of the air source connector 30, and the air source connector 30 is protectively covered between the first avoidance hole 1211 and the second avoidance hole 1221.

[0042] In some embodiments, each protection seat 12 can be configured to be able to move relative to each other within a certain distance only through the movable connection component 11, that is, any two protection seats 12 cannot be separated from each other. It can be understood that in this type of embodiment, when each protection seat 12 moves through the movable connection component 11, the aperture of the first avoidance hole 1211 and / or the second avoidance hole 1221 can be correspondingly increased. In this way, the change in aperture can enable the air source connector 30 to enter between the first avoidance hole 1211 and the second avoidance hole 1221 when needed, and to correspondingly exit between the first avoidance hole 1211 and the second avoidance hole 1221 when needed.

[0043] In other embodiments, on two adjacent protection seats 12, one side of one protection seat 12 can be detachably connected to the other side of the other protection seat 12. Thus, the entire covering device 1 can be removed from the gas source connector 30 by correspondingly unlocking the detachable connection position.

[0044] like Figure 3 and Figure 4 As shown, in some embodiments of the gas source lock 10 , the aperture of the first avoidance hole 1211 is adapted to the diameter of the gas source pipeline 40 , and the second avoidance hole 1221 is for the gas connecting pipe to be inserted and connected to the gas source connector 30 .

[0045] It can be understood that the aperture of the first avoidance hole 1211 is equal to or slightly larger than the diameter of the gas source pipeline 40, so as to prevent the gas source connector 30 from being directly withdrawn from the first avoidance hole 1211, and ensure that the covering device 1 can be removed only after the detachable locking member 21 is removed. The gas connection pipe is used to guide the gas on the gas source connector 30 to the device, equipment or component using the gas source.

[0046] like Figure 1 and Figure 3 As shown, in some embodiments of the air source lock 10 , each protection seat 12 is provided with a receiving groove 123 , and each receiving groove 123 is used to receive the air source connector 30 .

[0047] It can be understood that the provision of the accommodating groove 123 can prevent the air source connector 30 from being squeezed when the protective seat 12 is closed.

[0048] like Figures 1 to 4 As shown, in some embodiments of the air source lock 10 , the covering device 1 includes two protection seats 12 , and the two protection seats 12 are movably connected via a movable connection assembly 11 .

[0049] It can be understood that the number of the protection seats 12 is configured to be two, which can reduce the number of protection seats 12 that need to be operated by maintenance personnel while ensuring that the gas source connector 30 can be fully protectively covered.

[0050] like Figure 1 As shown, in some embodiments of the air source lock 10, the movable connection component 11 includes a rotating seat 111 and a rotating shaft 112, the rotating seat 111 is arranged on one of the protective seats 12, the rotating shaft 112 is arranged on the other protective seat 12, and the rotating shaft 112 is rotatably connected to the rotating seat 111.

[0051] It can be understood that the rotating seat 111 is provided with a hole for installing the rotating shaft 112, and the two protection seats 12 can rotate relative to each other through the rotating seat 111 and the rotating shaft 112. The number of rotating seats 111 and the number of rotating shafts 112 can be flexibly set; further, each rotating shaft 112 can be configured to be a one-to-one corresponding rotating connection relationship with each rotating seat 111, or multiple rotating shafts 112 can be configured to be rotatably set on the rotating seat 111, or one rotating shaft 112 can be rotatably set on multiple rotating seats 111.

[0052] like Figure 1 and Figure 4 As shown, in some embodiments of the air source lock 10, each locking position 22 is provided with a locking hole, and each locking hole is configured to be aligned with each other when each protective seat 12 can be closed and retracted, and a detachable locking member 21 is passed through and fixed to each locking hole.

[0053] It can be understood that the locking hole is a through hole for the detachable locking member 21 to pass through and fix. The locking hole can be configured to be opened on the convex edge of the protection seat 12.

[0054] Specifically, in some embodiments of the gas source lock 10, the detachable locking member 21 includes a password lock. It can be understood that the password lock has the advantages of low cost and easy use, and the maintenance personnel can modify the corresponding password before each use, further avoiding other people's misoperation of the gas source connector 30.

[0055] like Figure 3 and Figure 4 As shown, the gas source system 20 in some embodiments of the present invention includes a gas source pipeline 40 and a gas source connector 30 , and the gas source lock 10 is detachably mounted and fixed on the gas source connector 30 .

[0056] It can be understood that the gas source pipeline 40 is used to guide the air flow to the gas source connector 30, and one or more gas source connectors 30 can be correspondingly provided on the gas source pipeline 40. After the gas source connector 30 is used accordingly, that is, after the external air pipe is connected to the gas source connector 30, each protective seat 12 on the covering device 1 can be correspondingly placed on the gas source connector 30 and locked by the locking device 2, thereby completing the protective covering of the gas source connector 30.

[0057] After the air source connector 30 is used, the detachable locking member 21 is removed, and the covering device 1 can be removed from the air source connector 30 .

[0058] like Figure 3 As shown, in some embodiments of the gas source system 20 , the gas source system 20 further includes a connecting line 50 , one end of the connecting line 50 is connected to the gas source pipeline 40 or the gas source connector 30 , and the other end of the connecting line 50 is connected to the gas source lock 10 .

[0059] It can be understood that the setting of the connecting line 50 makes there a one-to-one correspondence between the gas source lock 10 and the gas source connector 30, thereby preventing the loss of the gas source lock 10. In the power plant, it is also convenient for operation and maintenance personnel to monitor the actual usage time of each gas source lock 10, so as to facilitate timely replacement of the gas source lock 10 that is nearing the limit of its service life.
