[0018] A centralized operation module for high protection distribution cabinets, see Figure 1-Figure 6, including: a panel 1, the panel 1 is fixedly connected to a mounting shell 2, the mounting shell 2 is detachably connected to an indicator light 3, the mounting shell 2 is slidably connected to a plurality of mounting rings 4, the mounting rings 4 are detachably connected to a button 5; a plurality of buckles 6, all fixedly connected to the panel 1; an elastic cover shell 7, which is sleeved on the panel 1, and an airbag portion 701 is provided on the elastic cover shell 7; a pressurizing shell 8 is fixedly connected to the panel 1, a pressurizing piston 9 is sealed and slidably connected inside the pressurizing shell 8, the pressurizing piston 9 cooperates with the pressurizing shell 8 to form a pressurizing chamber 901, the pressurizing piston 9 is fixedly connected to a push rod 10 slidably connected to the pressurizing shell 8, there is friction between the pressurizing shell 8 and the push rod 10, and the pressurizing chamber 901 is connected to the airbag portion 701; the maximum distance between the connecting point of the airbag portion 701 and the pressurizing shell 8 and the end face of the pressurizing chamber 901 away from the pressurizing piston 9 is less than the thickness of the pressurizing piston 9; the panel 1 is provided with a rectangular groove 702, and the airbag portion 701 is located in the rectangular groove 702.

[0019] In the above scheme, it is intended to solve the problem that the operating module of the existing distribution cabinet is exposed to the external environment, so that dust and water vapor invade the button 5 on the operating module, causing poor contact or even short circuit of the button 5; this scheme uses an elastic cover 7 to isolate the button 5 from the external environment, reducing the probability of dust and water vapor in the external environment invading the button 5, thereby increasing the service life of the button 5; the panel 1 is installed on the cabinet door of the distribution cabinet through the buckle 6, and the panel 1 and the cabinet door are sealed by the airbag part 701, on the one hand, preventing external dust and water vapor from entering the interior of the distribution cabinet and affecting the wiring of the indicator light 3 and the button 5, and on the other hand, improving the panel 1 and the elastic cover The shell 7 fits tightly, thereby improving the protective effect of the elastic cover shell 7 on the button 5; the elastic cover shell 7 is made of silicone rubber with high elasticity, aging resistance, high and low temperature resistance, and chemical corrosion resistance. The positions on the elastic cover shell 7 corresponding to the button 5 and the indicator light 3 are provided with markings, which can show the functions of the button 5 and the indicator light 3 corresponding to the position on the elastic cover shell 7. At the same time, the position of the elastic cover shell 7 corresponding to the indicator light 3 adopts a high-transparency material to ensure that the operator can clearly observe the status of the indicator light 3; the number of indicator lights 3 and buttons 5 can be changed according to actual conditions. In this article, the number of buttons 5 is three, and the three buttons 5 are respectively used for opening, closing and energy storage.

[0020] The maximum distance between the connection between the airbag part 701 and the pressurizing shell 8 and the end face of the pressurizing chamber 901 away from the pressurizing piston 9 is less than the thickness of the pressurizing piston 9. This setting is used for, after the operator installs the panel 1 on the cabinet door, to push the pressurizing piston 9 through the push rod 10 to squeeze the gas in the pressurizing chamber 901 into the airbag part 701, so as to expand the airbag part 701, so as to improve the sealing performance of the airbag part 701 to the gap between the panel 1 and the cabinet door, and finally the volume of the pressurizing chamber 901 is reduced to zero. At this time, the pressurizing piston 9 blocks the connection between the airbag part 701 and the pressurizing shell 8, so that the reaction force of the gas in the airbag part 701 on the pressurizing piston 9 is changed from left to rearward, and the pressurizing piston 9 is pushed left by the gas The thrust is reduced, which improves the stability of the pressurizing piston 9 during use of the distribution cabinet, maintains the pressure in the airbag part 701 stable, and maintains the sealing performance of the airbag part 701 to the gap between the panel 1 and the cabinet door; there is friction between the pressurizing shell 8 and the push rod 10, which further improves the stability of the pressurizing piston 9 when sealing the connection between the airbag part 701 and the pressurizing shell 8; the existence of the rectangular groove 702 limits the deformation of the airbag part 701 in the vertical direction, so that the squeezing force of the airbag part 701 on the gap between the panel 1 and the cabinet door is greater, which improves the stability of the elastic cover shell 7 on the panel 1 on the one hand, and improves the sealing performance of the airbag part 701 to the gap between the panel 1 and the cabinet door on the other hand.

[0021] See also Figure 2 and Figure 7 , and also includes: an extrusion frame 11 with an equal number to the buckle 6, which is limitedly slidably connected to the position of the panel 1 near the buckle 6, the airbag part 701 is used to squeeze the extrusion frame 11, and the panel 1 is rotatably connected with swing bars 12 with a number twice that of the buckle 6, and the extrusion frame 11 limits the adjacent buckles 6 through two adjacent swing bars 12; the buckle 6 is composed of a claw and a clamping arm, and the minimum distance between the buckle 6 and the adjacent swing bar 12 is greater than the height of the claw on the buckle 6; the button 5 passes through the adjacent mounting ring 4 and protrudes out of the mounting shell 2, and the length of the button 5 protruding out of the mounting shell 2 is less than the maximum distance between the mounting shell 2 and the elastic cover shell 7.

[0022] In the above scheme, it is intended to solve the problem that when the operating panel 1 is fixed to the cabinet door of the power distribution cabinet by using the existing buckle 6, if the distance between the operating panel 1 and the claw (the claw is the protruding part on the clamping arm of the buckle 6) is just equal to the thickness of the cabinet door, the buckle 6 may not be completely in place, and if the distance between the operating panel 1 and the claw is greater than the thickness of the cabinet door, the operating panel 1 may not be tightly attached to the surface of the cabinet door. This scheme makes it easier to fix the buckle 6 in place by making the distance between the panel 1 and the claw on the buckle 6 greater than the thickness of the cabinet door, and then uses the expansion of the airbag part 701 to seal the gap between the panel 1 and the cabinet door, while improving the panel 1 Stability during use; the buckle 6 is made of elastic metal, and the minimum distance between the buckle 6 and the adjacent swing bar 12 is greater than the height of the claw on the buckle 6. In the process of the buckle 6 being inserted into the cabinet door, the buckle 6 will be deformed due to the cabinet door squeezing the claw. At this time, the swing bar 12 does not affect the deformation of the adjacent buckle 6; the mounting shell 2 is designed as a rectangular shell, so that the side of the button 5 that is pressed is covered by the mounting shell 2, so that the button 5 does not contact the elastic cover shell 7. In this case, the elastic cover shell 7 tends to be flat as a whole. In the process of pressing the button 5 through the elastic cover shell 7, the elastic cover shell 7 will undergo a large range and uniform deformation, thereby extending the service life of the elastic cover shell 7.

[0023] The overall working principle of the above scheme is as follows: when installing the operating module on the cabinet door of the distribution cabinet, the operator first sets the elastic cover shell 7 on the panel 1, and installs the indicator light 3 and the button 5 at the specified position on the panel 1, and then uses the buckle 6 to install the panel 1 into the reserved hole on the cabinet door. At this time, the operator pushes the pressurizing piston 9 through the push rod 10 to squeeze the pressurizing chamber 901, and squeezes the gas in the pressurizing chamber 901 into the airbag part 701, so that the airbag part 701 expands. While the airbag part 701 expands, all the extrusion frames 11 are squeezed toward the center of the panel 1, so that the extrusion frame 11 slides along the panel 1 and drives the two adjacent swing bars 12 to swing, so that the swing bar 12 contacts the rear of the adjacent buckle 6, and limits the claw of the buckle 6 to prevent the claw of the buckle 6 from slipping due to uneven force (for example, the contact position between the cabinet door and the claw is an inclined surface, so that the claw has a tendency to slide toward the center of the panel 1).

[0024] See also Figure 2 and Figure 8-Figure 11, also includes: a lock head 13, which is fixed to the panel 1 and passes through the elastic cover shell 7, a swinging piece 14 is fixed to the side of the lock head 13 away from the elastic cover shell 7, a torsion spring is fixed between the swinging piece 14 and the lock head 13 shell, the swinging piece 14 is hinged with a transmission bar 15, a side of the mounting ring 4 away from the elastic cover shell 7 is rotatably connected with a swivel 16, adjacent swivels 16 are driven by a belt, the transmission bar 15 is hinged with adjacent swivels 16, the swivel 16 passes through the adjacent mounting ring 4 and is fixed with a rotating shell 17, a side of the rotating shell 17 away from the adjacent swivel 16 is fixed with a mounting frame 18, and the mounting frame 18 is fixed with an extrusion arc block 19; the same number of locking members 20 as the mounting frame 18 are all fixed to the side of the elastic cover shell 7 close to the mounting frame 18, and the extrusion arc block 19 is used to limit the adjacent locking members 20.

[0025] In the above scheme, it is intended to solve the problem that during the use of the existing distribution cabinet operation module, people accidentally touch the button 5, causing accidental start-up and accidental shutdown; in this scheme, the extrusion arc block 19 is used to limit the locking member 20 to protect the button 5, so that when an accidental touch occurs, the person cannot press the button 5, thereby preventing the erroneous operation caused by the accidental touch; the lock head 13 can be replaced by a knob, and the front side of the lock head 13 clamps the elastic cover shell 7 between it and the panel 1 to ensure the sealing between the panel 1 and the elastic cover shell 7; the purpose of setting a torsion spring between the swinging member 14 and the lock head 13 is to facilitate reminding the operator to close the lock head in time after the operation is completed 13, so that the extrusion arc block 19 can re-limit the adjacent locking member 20 to prevent erroneous operation caused by the operator's failure to close the lock 13 in time; the number of extrusion arc blocks 19 can be freely replaced. In this scheme, the number of extrusion arc blocks 19 is two. The locking member 20 is composed of a cylindrical connecting rod and two fan-shaped extrusion blocks located on the rear side. The connecting rod of the locking member 20 is fixed to the elastic cover shell 7. Initially, the extrusion block of the locking member 20 contacts the adjacent extrusion arc block 19. At this time, the locking member 20 is limited by the extrusion arc block 19 and cannot move backward; inclined surfaces can be set on both sides of the circumference of the extrusion arc block 19 to assist the adjacent locking member 20 in resetting.

[0026] See also Figure 2 , Fig.11 and Fig.12, also includes: a delay shell 21, which is hinged to the side of the swinging member 14 away from the transmission bar 15, the delay shell 21 is hinged to the swivel 16 close to the transmission bar 15, and a delay cavity 211 is arranged in the delay shell 21; a limiting member 22 is sealingly and slidably connected in the delay cavity 211, a first spring is fixedly connected between the limiting member 22 and the delay shell 21, and the elastic coefficient of the first spring between the limiting member 22 and the delay shell 21 is smaller than the elastic coefficient of the torsion spring between the swinging member 14 and the lock head 13, a limiting groove 221 is arranged on the mounting shell 2, the limiting member 22 limits the delay shell 21 through the limiting groove 221, and a limited flow hole 222 is arranged on the limiting member 22; a one-way valve 23 is fixedly connected to the limiting member 22, and is used to connect the delay cavity 211 located on both sides of the limiting member 22.

[0027] In the above scheme, when the operator presses the button 5, the limiter 22 is used to temporarily limit the swing member 14, so that the swing member 14 can reset itself under the action of its adjacent torsion spring after a period of time, so that the extrusion arc block 19 can limit the adjacent locking member 20 again; the delay chamber 211 can store liquid medium (such as hydraulic oil), and the hydraulic oil flows through the limited flow hole 222 to buffer the limiter 22; the one-way valve 23 is connected in the direction from front to back; the front end of the limiter 22 is spherical, and the limit groove 2 21 is hemispherical, so that the limit member 22 can be retracted into the delay shell 21 when it slides relatively along the limit groove 221; initially, the first spring adjacent to the limit member 22 is in a compressed and force-accumulating state; the elastic coefficient of the first spring between the limit member 22 and the delay shell 21 is smaller than the elastic coefficient of the torsion spring between the swing member 14 and the lock head 13, so that the swing member 14 has a tendency to reset after rotation, and under the action of the torsion spring adjacent to the swing member 14, the delay shell 21 has a tendency to move downward, that is, the limit member 22 has a tendency to slide downward out of the limit groove 221.

[0028] See also Figure 11-13 , further comprising: an extrusion piston 24, which is sealingly and slidably connected to the delay shell 21, the extrusion piston 24 cooperates with the delay shell 21 to form an extrusion chamber 212, and the extrusion piston 24 is used to extrude the limiter 22; an extrusion ring 25 equal in number to the rotating shell 17, which is sealingly and slidably connected to the adjacent rotating shell 17, a second spring is fixedly connected between the rotating shell 17 and the adjacent extrusion ring 25, the extrusion ring 25 cooperates with the adjacent rotating shell 17 to form a power chamber 251, the extrusion ring 25 is fixedly connected to the pull rope 26, the pull rope 26 is laid on the adjacent mounting frame 18, the locking member 20 is used to extrude the adjacent pull rope 26, a first guide hole 161 is provided in the rotating ring 16, a second guide hole 162 is provided in the rotating shell 17, the second guide hole 162 is communicated with the adjacent first guide hole 161, the first guide holes 161 on the adjacent rotating rings 16 are communicated through a conduit, and the extrusion chamber 212 is communicated with the adjacent first guide hole 161 through a conduit.

[0029] In the above scheme, the purpose is to use the action of the operator pressing the button 5 to extend the duration of the movement timing of the limit member 22; initially, the extrusion piston 24 contacts the rear end of the limit member 22; hydraulic oil is stored in the power chamber 251 and the extrusion chamber 212; the pull rope 26 can be made of a flexible and low-ductility material; the rotating shell 17 is composed of a stepped shell and two connecting columns inside it, and the second guide hole 162 is arranged in the connecting column of the rotating shell 17. Among the three rotating shells 17, the rotating shell 17 located in the middle is provided with two second guide holes 162, and the middle rotating ring 16 is provided with two first guide holes 161. The rotating shells 17 on the left and right sides are each provided with a second guide hole 162, and the rotating rings 16 on the left and right sides are each provided with a second guide hole 162. The three power chambers 251 are connected to each other through the connection between adjacent first guide holes 161.

[0030] See also Fig. 9 , and also includes: elastic rings 27 whose number is equal to the mounting rings 4, respectively fixed to adjacent mounting rings 4, the elastic rings 27 are in contact with the mounting shell 2, and the maximum outer diameter of the rotating shell 17 is greater than the maximum outer diameter of the mounting rings 4.

[0031] In the above scheme, it is intended to prevent the button 5 from being accidentally touched by the outside world with too much force, thereby damaging the extrusion arc block 19 and the adjacent locking member 20, resulting in the button 5 being accidentally triggered; the elastic ring 27 is made of elastic rubber, and the mounting ring 4 is a stepped ring, that is, the outer diameter of the middle part of the mounting ring 4 is greater than the outer diameter of the front side thereof, and the elastic ring 27 is fixedly connected to the front side of the adjacent mounting ring 4, fixing the mounting ring 4 to the mounting shell 2 (see attached Fig. 9 ); After the button 5 is subjected to excessive force, the button 5 drives the adjacent mounting ring 4 to move backward, and the mounting ring 4 drives the elastic ring 27 to move and squeeze with the mounting shell 2, and the elastic ring 27 is deformed, so that the button 5 drives the mounting ring 4 to move backward as a whole by the length of the central axis of the rotating shell 17, thereby preventing the button 5 from being triggered by mistake; the stepped shell of the rotating shell 17 is used to limit the moving distance of the button 5, thereby preventing the button 5 from being squeezed and moved too long, causing the wire connected to the button 5 to be pulled and fall off.

[0032] The working principle of the above scheme is as follows: when it is necessary to operate the distribution cabinet, the operator uses the key to rotate the lock 13 counterclockwise (the rotation perspective in this article is from front to back), the parts inside the lock 13 drive the swing member 14 to rotate, and twist the torsion spring adjacent to the swing member 14, the swing member 14 drives the middle rotating ring 16 to rotate counterclockwise through the transmission bar 15 and the delay shell 21, the middle rotating ring 16 rotates counterclockwise through the two rotating rings 16 on both sides of the belt drive, the rotating ring 16 drives the adjacent rotating shell 17 and the mounting bracket 18 to rotate, the mounting bracket 18 drives the adjacent extrusion arc block 19 to rotate, after the lock 13 rotates 90°, the extrusion arc block 19 loses contact with the extrusion block of the adjacent locking member 20, and the limit member 22 corresponds to the limit groove 221, at this time, the limit member 22 enters the limit groove 221 under the action of the adjacent first spring (at this time, the limit member 22 is in the extreme position, and the rear end of the limit member 22 loses contact with the extrusion piston 24).

[0033] After the operator rotates the lock head 13 90°, the operator pulls out the key. At this time, the swing member 14 is limited by the limit member 22 and is in a static state. The limit member 22 is slowly moved into the delay shell 21 by the force of the adjacent torsion spring of the swing member 14 and compresses the first spring (the distance between the rear end of the limit member 22 and the extrusion piston 24 gradually decreases). At this time, the operator presses the position of the corresponding button 5 on the elastic cover shell 7, and the elastic cover shell 7 drives the corresponding locking member 20 to move backward. The locking member 20 squeezes the adjacent pull rope 26 and the adjacent button 5, so that the button 5 is triggered, and the pull rope 26 pulls the adjacent extrusion ring 25 forward. The extrusion ring 25 passes the hydraulic oil in the adjacent power chamber 251 through the adjacent second guide hole 162 and the adjacent first guide hole 161 and the conduit are transported to the extrusion chamber 212, and the hydraulic oil in the extrusion chamber 212 pushes the extrusion piston 24 forward. During the movement, the extrusion piston 24 contacts the limit member 22 and pushes the limit member 22 back to the limit position. After the operator triggers the corresponding button 5, the operator releases the finger pressing the elastic cover shell 7. At this time, the elastic cover shell 7 drives the locking member 20 to reset under its own elastic action, the button 5 is reset, and the pull rope 26 is reset under the action of the first spring on the adjacent extrusion ring 25. At this time, the volume in the power chamber 251 increases and draws back the hydraulic oil in the extrusion chamber 212, so that the extrusion piston 24 is reset. At this time, the limit member 22 starts to move again and timing.

[0034] During the backward movement of the limit member 22, if the operator does not continue to press the button 5, then when the limit member 22 is reset relative to the delay shell 21, the swing member 14 rotates 90° clockwise under the action of the adjacent torsion spring and resets, and the above-mentioned steps of rotating the swing member 14 counterclockwise are repeated in reverse, so that the extrusion arc block 19 limits the adjacent locking member 20 again; if the operator continues to press the button 5 during the backward movement of the limit member 22, the above-mentioned steps of pressing the button 5 are repeated at this time, so that the limit member 22 moves forward to the extreme position and moves the timing again after the operator releases the button 5.
