The working process and principle are as follows:

when the device is used, when a maintenance person steps on the lower pressing plate 4 connected in the water tank 3 in a sliding manner, the lower pressing plate 4 moves downwards under the action of gravity, the lower pressing plate 4 moving downwards presses water in the water tank 3, the pressed water flows into the column groove 7 from the water pipe 6 communicated with the water tank 3, the water entering the column groove 7 pushes the foam body 8 to move upwards in the column groove 7, the moving foam body 8 drives the fixedly connected magnet I9 to move upwards in the column groove 7 together, the space in the column groove 7 is limited, the foam body 8 and the magnet I9 which are fixedly connected are pushed to the upper end of the column groove 7 by the downward gravity of the maintenance person, the movable block 19 is known to be inserted at the top of the column groove 7, so the magnet I9 moving to the upper end pushes the movable block 19, and the magnet I9 and the magnet II 11 are positioned on the same horizontal plane at the same time when the movable block 19 is pushed, because the polarities of the first magnet 9 and the second magnet 11 are opposite, the first magnet 9 in the column groove 7 repels the second magnet 11, the repelled second magnet 11 moves away from the column groove 7, but the blocking rod 17 connected with the sliding rod 15 and the limiting rod 12 in a sliding way can obstruct the movement of the limiting rod 12 under the limitation of the inclined blocking column 18, when the first magnet 9 continuously pushes the moving block 19 to move upwards, the lifting rod one 20 fixed on the moving block 19 can lift the blocking rod 17 on the moving path under the driving of the moving block 19, when the blocking rod 17 is lifted, the blocking rod 17 can be separated from the limitation of the inclined blocking column 18, at the moment, the limitation of the limiting rod 12 is released, the second magnet 11 fixedly connected with the limiting rod 12 can also be limited in a contact way, the second magnet 11 without limitation can be far away from the column groove 7 under the repulsion of the first magnet 9, and the limiting rod 12 rotates by taking the torsion spring 13 as the axis, therefore, the second magnet 11 far away from the column groove 7 drives the limiting rod 12 fixedly connected with the second magnet to rotate clockwise by taking the axis 13 of the torsion spring as the axis, and it is known that in an initial state, one end of the limiting rod 12 close to the limiting block 14 and the limiting block 14 are located on the same vertical plane, one end of the limiting rod 12 which rotates clockwise and moves circumferentially, close to the opening and closing door 2, is gradually far away from the opening and closing door 2, namely is no longer located on the same vertical plane as the limiting block 14, and at this time, the first locking structure is released; under normal conditions, the water in the column groove 7 can not be pushed by the weight of the child to rise to the same horizontal plane with the second magnet 11, even if the fat child pushes the first magnet 9 in the column groove 7 to rise to the same horizontal plane with the second magnet 11, the first locking structure is released, and the device still has the second locking structure to prevent the child from mistakenly touching

furthermore, because of the heavy weight of an adult, the space in the column groove 7 is limited, the first magnet 9 can push the moving block 19 positioned in the column groove 7 to the highest position, at the moment, the first electric contact 22 positioned on the moving block 19 can be in contact with the third electric contact 24, the known circuit of the power distribution cabinet can be cut off when the first electric contact 22 is in contact with the third electric contact 24, the circuit does not need to be manually cut off by maintenance personnel at the moment, and the maintenance work of the maintenance personnel is facilitated.

Furthermore, when the maintenance personnel steps on the lower pressing plate 4, because the adult has a heavier weight than the child, when the adult stands on the lower pressing plate 4, the first locking structure is directly released, the maintenance personnel only need to insert the key 28 into the keyhole 27, rotate the key 28 clockwise, the clockwise rotated key 28 presses down the notch piece 30 on one side, the pressed notch piece 30 moves downward in the reset body 29, the downward moved notch piece 30 makes the limited rotating wheel 25 and the notch piece 30 on the same horizontal plane, at this time, the rotating wheel 25 in the notch of the notch piece 30 releases the limitation of the notch piece 30 and starts rotating clockwise, the clockwise rotated rotating wheel 25 will drive the meshed set of toothed bars 26 to expand outward, and the known toothed bars 26 are fixedly connected with the opening and closing door 2, so the outward expanded toothed bars 26 will drive the opening and closing door 2 to expand outward, the door of the switch board is opened at this time. [ namely, only an adult stands on the lower pressing plate 4, and turns the key 28 to expand and open the opening and closing door 2 in the shell 1. in addition, the opening and closing door 2 is designed to be expanded and opened, and the safety is improved compared with the traditional outward-pulling type ]

Furthermore, when a child or an overhaul person gets down from the lower pressing plate 4, the water in the column groove 7 returns to the water tank 3 under the action of gravity, the foam body 8 floating up from the water in the water tank 3 and the first magnet 9 fixedly connected with the foam body 8 both fall back to the bottom of the column groove 7, in the falling back, the moving block 19 pushed up by the first magnet 9 returns to the initial state from the top end of the column groove 7, in the recovery process, the first electrical contact 22 on the moving block 19 does not contact with the third electrical contact 24, at the moment, the circuit in the power distribution cabinet is connected, in addition, the first electrical contact 22 contacts the second electrical contact 23 again, at the moment of contact, the rotating wheel 25 starts to rotate counterclockwise, because the teeth of the rotating wheel 25 are thick, although there is a falling tendency, the rotating wheel 25 only needs to rotate for a very small number of turns, and the rotating wheel 25 rotating counterclockwise drives the opening and closing door 2 fixedly connected with the rack bar 26 to finish inward contraction in the housing 1, in addition, the first lifting rod 20 moving downwards together with the moving block 19 can not lift the clamping rod 17 any more, because the clamping rod 17 is connected with the limiting rod 12 through the sliding rod 15, under the action of the torsion spring in the torsion spring axis 13 connected with the limiting rod 12, the limiting rod 12 can bring the clamping rod 17 connected with the limiting rod to restore to the initial state, when the clamping rod 17 restores to the initial state, the clamping rod 17 can slide on the inclined surface of the inclined surface clamping column 18, then returns to the notch of the inclined surface clamping column 18 under the assistance of the spring 16 to restore to the initial position, and the end of the limiting rod 12 close to the limiting block 14 is known to be of a telescopic structure, the limiting block 14 is U-shaped, the surface of the U-shaped bottom end of the limiting block 14 far away from the opening and closing door 2 is of the inclined surface clamping column 18, so that when the opening and closing door 2 is closed, the telescopic limiting rod 12 can slide into the limiting block 14 on the inclined surface of the limiting block 14, thereby realizing the limitation on the opening and closing door 2 again, at this time, the maintenance personnel only need to rotate the key 28 counterclockwise, and the notch piece 30 pressed down by the key 28 is restored to the initial state under the action of the reset spring arranged in the reset body 29, so that the double locking of the power distribution cabinet is realized again.

To sum up, this have and prevent that children mistake touches dual-locking switch board that conveniently opens, because of the device carries out the door opening and closing operation with a magnetite 9 in post groove 7, under normal conditions, children's weight can not make the water in post groove 7 promote magnetite 9 rise to be in same horizontal plane with magnetite two 11, just also can not make first locking structure opened to prevent to take place the danger of electrocuteeing because of the switch board is opened children.

This have and prevent children mistake and touch dual lock switch board that conveniently opens, even if more fat children make the water in the post groove 7 promote that the magnetite 9 rises to be in same horizontal plane with magnetite two 11, first locking structure is relieved, this device still has the second to say the locking structure, if do not have key 28 to push down breach piece 30, breach piece 30 can not relieve the restriction to rotating wheel 25, so even first locking structure is opened, the second says that the locking structure still can make the switch board locking.

This have and prevent children mistake and touch dual-locking switch board that conveniently opens, because of adult's weight is heavier, post groove 7 inner space is limited, magnetite one 9 can push away the movable block 19 that is arranged in post groove 7 to the highest point, at this moment, the electric contact one 22 that is arranged in on the movable block 19 can take place to contact with electric contact three 24, known when electric contact one 22 and electric contact three 24 contact, the circuit of switch board can be cut off, need not the manual circuit cut-off of maintainer this moment, make things convenient for maintainer's maintenance work.

This have and prevent that children's mistake touches dual-locking switch board of conveniently opening can descend in basin 3 when holding down plate 4 is stepped on, because there is the support of hydraulic stem 5 when descending, even have the overweight weight to push down on the basin 3 and can not make and basin 3 have the post groove 7 of the relation of intercommunication to take place to break because of the pressure of water yet, and water can enter into the switch board after breaking and take place danger.

This dual-locking switch board with prevent children mistake and touch convenient opening only needs the adult to stand on holding down plate 4, twists key 28 and can make the expansion of the door 2 that opens and shuts in casing 1 open, and when switch board locking state, the door 2 surface that opens and shuts does not have any handle that can stimulate only a plane, and the mode of this kind of outside expansion has increased the security than traditional outer drawing formula.

First locking structure is through the different effects that the mechanical principle realization produced under different gravity circumstances, compare gravity sensor and say that mechanical structure can not receive the influence of the interior electrical part of switch board, because gravity sensor can receive electromagnetic interference to a certain extent, a large amount of power equipment can influence the measurement of sensor in the switch board, make gravity sensor can produce the erroneous judgement because of measurement accuracy's error at the during operation, if children step on and lead to locking structure to open because of measurement error, the device just can not play the effect of locking like the nominal.

Gravity sensor can receive service environment's influence, and in rainy day or plum rain season, gravity sensor who uses in the open air can wet, and the information transmission of the gravity sensor who wets back can receive the influence of certain degree, if it is serious probably unable the use to wet, in addition, the sensor also can receive high low temperature's interference, and mechanical structure then does not receive the influence of these factors.

In addition, the device uses through mechanical structure's cooperation and reaches anticipated effect, need not additionally to add electric power, and is energy-concerving and environment-protective, if use gravity sensor to control in addition, the locking structure that it controlled just can't use when gravity sensor's circuit goes wrong.
