[0048] The power control cabinet also includes: a first guide rod 203, a first mounting plate 301 fixedly connected to one end of the first guide rod 203; a second guide rod 303, a second mounting plate 302 fixedly connected to one end of the second guide rod 303; a first cavity is provided on the first guide rod 200, and a second cavity is provided on the second guide rod 300, the first guide rod 203 is penetrated in the first cavity, and the second guide rod 300 is penetrated in the second cavity; a first movable groove is provided on the side of the top of the first cavity, the first guide rod 203 is connected to the first mounting plate 301 through a first connecting block, the first connecting block is penetrated in the first movable groove, and the second guide rod 303 is connected to the second mounting plate 302 through a second connecting block, the first guide rod 203 and the second guide rod 303 play a guiding role in the movement of the first mounting plate 301 and the second mounting plate 302, and ensure that the first mounting plate 301 and the second mounting plate 302 move along the specified direction.

[0049] A support block 102 is provided on the inner wall of the cabinet 100, and the second mounting plate 302 is provided on the top of the support block 102; the support block 102 provides support force for the second mounting plate 302 to ensure the stability of the second mounting plate 302 when used; there is a gap between the side wall of the first mounting plate 301 and the side wall of the cabinet 100, and the support block 102 is provided between the gap between the first mounting plate 301 and the side wall of the cabinet 100. After the second mounting plate 302 is moved away from the bottom of the first mounting plate 301, the second mounting plate 302 is still on the support block 102. The support block 102 is used to provide support for the second mounting plate 302, thereby reducing the force on the end of the second guide rod 303 and protecting the second guide rod 303.

[0050] The first cavity is filled with hydraulic oil, and a connecting cavity for connecting the first cavity and the second cavity is provided on the top of the first guide rod 200; the first push plate 222 is provided in the first cavity, and the hydraulic oil is between the first push plate 222 and the first guide rod 203, and a liquid inlet cavity and a liquid outlet cavity are provided at the bottom of the first cavity; an oil storage tank can be connected to the side wall of the cabinet 100, and the oil storage tank is connected to the liquid inlet cavity and the liquid outlet cavity.

The maximum stroke of the material discharge chamber is limited; a sealing block 213 is provided in the material discharge chamber. When hydraulic oil enters the material discharge chamber, the sealing block 213 closes the material discharge chamber, and the bottom of the first cavity and the first push plate 222 form a sealed space. After the hydraulic oil enters the first cavity, it pushes the first push plate 222 to move. The hydraulic oil at the top of the first push plate 222 enters the second cavity through the connecting cavity. The hydraulic oil pushes the second guide rod 303 to move, and the second mounting plate 302 is moved away from the bottom of the first mounting plate 301; after the second limiting plate 3031 moves to one end of the second cavity, the material discharge chamber is opened. At this time, the first mounting plate 301 loses its supporting force. After the first guide rod 203 falls down, it falls on the first push plate 222. The cross-section of the discharge cavity is much smaller than the cross-section of the first cavity. By limiting the cross-section of the discharge port, the flow of the storage cavity is limited, and the hydraulic oil can only flow out of the storage cavity slowly, slowing down the descending speed of the first push plate 222, thereby playing a supporting role for the first mounting plate 301, slowing down the descending speed of the first mounting plate 301, and preventing the first guide rod 203 from falling directly on the bottom of the first cavity, thereby protecting the first mounting plate 301; after the maintenance of the control cabinet is completed, the hydraulic oil is pumped into the first cavity again, and the liquid at the bottom of the first push plate 222 The pressurized oil pushes the first push plate 222 to move upward, and the first push plate 222 pushes the first guide rod 203 to move upward, and the first mounting plate 301 moves upward together with the first guide rod 203. After the first mounting plate 301 moves away from one side of the second mounting plate 302, the first reset spring 304 pushes the second limit plate 3031 to move back, and the second guide rod 303 drives the second mounting plate 302 to move toward the middle of the cabinet 100, and the second mounting plate 302 moves back to the bottom of the first mounting plate 301 to provide support force for the first mounting plate 301, thereby completing the reset of the first mounting plate 301 and the second mounting plate 302.
