In the present embodiment, the propulsion mechanism 1 is preferably, but not limited to, an electric propulsion mechanism including a slide plate 11, a slider 12, a lead screw 13, and a motor 14. The slide plate 11 has an elongated plate shape. The sliding block 12 is connected with the sliding plate 11 in a sliding way, and the sliding block 12 is used for fixing the push rod 4. The screw 13 is disposed in parallel with the slide plate 11 and is screwed with the slider 12 to drive the slider 12 to move in the extending direction of the slide plate 11 when rotated. The motor 14 is fixed at one end of the sliding plate 11 and can drive the screw rod 13 to rotate, so that the sliding block 12 drives the push rod 4 to slide along the extending direction of the sliding plate 11, the push rod 4 is pressed against the pin rod after moving towards the pin rod, and the baffle is opened, or the push rod 4 is reset and closed after moving away from the pin rod.
Alternatively, the propulsion system 1 may also be a hand-operated propulsion system. For example, the hand-operated propulsion mechanism may be similar to the electric propulsion mechanism described above, except that a crank may be provided at an end of the lead screw 13 instead of the motor 14 to drive the lead screw 13 to rotate forward or backward by hand-operated means, thereby propelling or retracting the push rod 4.

In this embodiment, for being applicable to the cubical switchboard of different degree of depth, slide 11 bottom can have a plurality of first connecting holes (not shown in the figure) that are used for connecting electro-magnet 3, and a plurality of first connecting holes are arranged along the extending direction of slide 11, through the different first connecting holes of position with electro-magnet 3 bolt to the different positions of slide 11, so that when the cubical switchboard is darker, with electro-magnet 3 bolt in the slide 11 one end of the side of stretching out of 4 push rods dorsad, or when the cubical switchboard is lighter, with electro-magnet 3 bolt in the middle part of slide 11, so as to be able to adsorb to the cubical switchboard inner wall in the finite space.
In this embodiment, the push rod 4 includes a first plate 41 and a second plate 42 connected to each other, the first plate 41 is disposed parallel to the slide plate 11, one end of the first plate 41 is detachably connected to the slider 12, and the other end is vertically connected to the second plate 42. The first plate 41 preferably has a plurality of second connection holes 20 for connecting the sliding block 12, and the plurality of second connection holes 20 are arranged along the extending direction of the first plate 41, so that the sliding block 12 and the push rod 4 can be bolted through the second connection holes 20 at different positions, and the extendable length of the push rod 4 can be adjusted, so that the opening tool can be further adapted to switch cabinets with different depths.
In consideration of the height position of the pin rod in the switch cabinet, the second plate 42 may further have a plurality of third connection holes 30 for connecting the first plate 41, and the plurality of third connection holes 30 are arranged along the extending direction of the second plate 42 so as to bolt the first plate 41 and the second plate 42 through the third connection holes 30 at different positions.
It is understood that adjusting the bolting position of the first plate 41 and the second plate 42 can adjust the height position of the second plate 42 when the second plate 42 is disposed in the vertical direction. When the second plate 42 is disposed along the horizontal direction, the width position of the second plate 42 can be adjusted, i.e. the extendable width of the opening tool can be further adjusted by cooperating with the adjusting mechanism 2. Then, when the second plate 42 is disposed obliquely, the height and width position thereof can be adjusted by adjusting the inclination angle thereof and the bolting position of the first plate 41.
In this embodiment, the adjusting mechanism 2 includes a third plate 21 and a fourth plate 22, one end of each of the third plate 21 and the fourth plate 22 is fixed to the pair of push rods 4, a plurality of fourth connecting holes 40 and a plurality of fifth connecting holes 50 are respectively formed in the third plate 21 and the fourth plate 22 in the extending directions, and the fourth connecting holes 40 and the fifth connecting holes 50 are used for bolting the third plate 21 and the fourth plate 22.

Because the size structure of the switch cabinet has standard industry standards, for example, the width of the 10kV handcart switch cabinet is usually 65cm, 85cm and so on, each fourth connecting hole 40 and each fifth connecting hole 50 respectively arranged on the third plate 21 and the fourth plate 22 can be set to be even 2.5cm or 5cm distance and so on, so as to be suitable for switch cabinets with different widths.
Of course, in alternative embodiments thereof, the third plate 21 and the fourth plate 22 may also have other configurations in which the connection position is adjustable. For example, a strip-shaped groove with the same extending direction as the third plate 21 is formed in the third plate 21, a plurality of through holes adapted to the width of the strip-shaped groove are formed in the fourth plate 22, the third plate 21 and the fourth plate 22 can be bolted and fixed by bolts penetrating through the strip-shaped groove and the through holes, and the connecting position of the third plate 21 and the third plate 21, that is, the total connecting length of the third plate 21 and the third plate 21 can be adjusted by adjusting the position of the adjusting bolts in the strip-shaped groove.
In particular, as a structure that directly protrudes into the switchgear cabinet and operates the pin lever, the push rod 4 is preferably made of SMC material, which has good SMC transparency and arc resistance. Meanwhile, the adjusting mechanism 2 and the push rod 4 are both load structures of the propelling mechanism 1, and the SMC also has the advantage of light specific gravity, so the adjusting mechanism 2 can be made of SMC materials besides the push rod 4.
The slide plate 11 is made of a metal material with good mechanical strength as a connecting structure fixedly connected with the electromagnet 3 and a basic structure for carrying the slide block 12, the screw rod 13, the motor 14, the push rod 4 and the adjusting mechanism 2. In this embodiment, the sliding plate 11 is preferably made of a galvanized steel plate, which has good comprehensive performance and high cost performance.
In this embodiment, the electromagnet 3 is preferably a suction cup type electromagnet, which has good adsorption stability and small volume, and can save the occupied space and facilitate installation.
In this embodiment, the opening tool further includes a remote controller (not shown in the figure), and the remote controller is electrically connected to the pushing mechanism 1 and/or the electromagnet 3, so that an operator can remotely operate the opening baffle when performing maintenance operations on the nuclear phase and other switch cabinets.
Considering that if the electromagnet 3 or the electric propulsion mechanism suddenly loses power in the maintenance operation, the opening tool suddenly releases the abutting force on the pin rod, so that the baffle is suddenly closed, and potential safety hazards are generated. To this end, in this embodiment, the opener further comprises a main power supply (not shown) and at least one backup power supply (not shown), wherein the main power supply is connectable to the municipal power grid for supplying power to the propulsion unit 1 and/or the electromagnet 3; the backup power supply is preferably a battery to supply power to the propulsion mechanism 1 and/or the electromagnet 3 when the main power supply is switched off, so that the opening tool ensures a continuous pressing against the pin and opening of the shutter.
It should be noted that the circuit configuration and configuration methods of the remote controller and the main power supply are all the prior art, and are not described herein.
It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Numerous obvious variations, adaptations and substitutions will occur to those skilled in the art without departing from the scope of the invention. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
