[0009] Preferably, the protective mechanism is a cover plate rotatably connected to the front end of the cabinet door, and the size of the cover plate is greater than or equal to the observation window.

[0010] Preferably, a mounting plate is fixedly connected to the bottom of the cover plate, a groove is provided on one side of the mounting plate, a spring is installed in the groove, a clamping block is installed on the end of the spring away from the groove, and a fixing plate is fixedly connected to the bottom of the observation window, a clamping groove is provided on one side of the fixing plate.

[0011] Preferably, a mounting groove is further provided on the other side of the mounting plate, a pull plate is slidably connected in the mounting groove, a connecting groove is further provided in the groove, the connecting groove is connected with the mounting groove, and a connecting rod is fixedly connected between the pull plate and the block.

[0012] Preferably, a pull ring is fixedly connected to one side of the pull plate.

[0013] Preferably, a base is fixedly connected to the bottom of the control cabinet body, and a forklift opening is provided on the base.

[0014] Preferably, a plurality of heat dissipation holes are provided on two opposite sides of the control cabinet body, and blocking plates are installed in the heat dissipation holes.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. The utility model sets a cover plate, and the size of the cover plate is greater than or equal to the observation window. Due to the blocking effect of the cover plate, the observation window on the cabinet door is reduced from being polluted by mud and water. The staff does not need to wipe the observation window repeatedly, but only needs to directly open the cover plate to observe the internal situation of the control cabinet body, which reduces the cleaning workload and labor intensity of the staff and ensures the reliable operation of the equipment.

[0017] 2. The utility model sets a card block and a card slot, and by pulling the pull plate upwards, the card block can be put into the groove. At this time, the cover plate can be rotated to make the position of the card block coincide with the card slot, and then the pull plate can be loosened to fix the card block in the card slot, so as to fix the cover plate and prevent the cover plate from shaking left and right, so that the cover plate will not be loosened or misplaced due to external shock or vibration; when it is necessary to open the cover plate and observe the internal situation of the control cabinet body through the observation window, the pull plate can be pulled outwards to make the card block unable to be fixed in the card slot, and then the cover plate can be rotated.

[0025] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0026] Embodiment 1: As shown in the attached Figure 1 To Attachment Figure 5 As shown: The utility model provides a control cabinet for power supply of a shield machine, including a control cabinet body 1, a cabinet door 4 is rotatably connected to the front end of the control cabinet body 1, an observation window 41 is opened on the cabinet door 4, and a protective mechanism is provided on the cabinet door 4 for protecting the observation window 41. The protective mechanism is a cover plate 52 rotatably connected to the front end of the cabinet door 4, and the size of the cover plate 52 is greater than or equal to the observation window 41.

[0027] As can be seen from the above, by setting the cover plate 52, and the size of the cover plate 52 is greater than or equal to the observation window 41, due to the blocking effect of the cover plate 52, the observation window 41 on the cabinet door 4 is reduced from being contaminated by mud and water. The staff does not need to repeatedly wipe the observation window 41, but only needs to directly open the cover plate 52 to observe the internal situation of the control cabinet body 1, thereby reducing the cleaning workload and labor intensity of the staff and ensuring the reliable operation of the equipment.

[0028] The bottom of the cover plate 52 is fixedly connected to a mounting plate 6, one side of the mounting plate 6 is provided with a groove 61, a spring 62 is installed in the groove 61, and a clamping block 63 is installed at the end of the spring 62 away from the groove 61. The bottom of the observation window 41 is fixedly connected to a fixing plate 5, one side of the fixing plate 5 is provided with a clamping groove 51.

[0029] A mounting groove 7 is also provided on the other side of the mounting plate 6, and a pull plate 71 is slidably connected in the mounting groove 7. A connecting groove 73 is also provided in the groove 61, and the connecting groove 73 is connected to the mounting groove 7. A connecting rod 74 is fixedly connected between the pull plate 71 and the block 63.

[0030] By setting the block 63 and the slot 51 and pulling the pull plate 71 upwards, the block 63 can be inserted into the groove 61. At this time, the cover 52 can be rotated to make the block 63 coincide with the position of the slot 51, and then the pull plate 71 can be released to fix the block 63 in the slot 51, thereby fixing the cover 52 and preventing the cover 52 from shaking left and right, so that the cover 52 will not become loose or misplaced due to external shock or vibration.

[0031] When it is necessary to open the cover plate 52 and observe the internal situation of the control cabinet body 1 through the observation window 41 , the pull plate 71 can be pulled outwards to make the block 63 unable to be fixed in the slot 51 , and then the cover plate 52 can be rotated.
