DETAILED DESCRIPTION

[0018] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0019] like Figure 1-Figure 3The manual swing-in and swing-out mechanism of the explosion-proof and intrinsically safe power distribution device for mining of the utility model shown in the figure comprises a door panel 4 and a circuit breaker trolley 11, the door panel 4 is provided with a shaft sleeve 14, the shaft sleeve 14 is provided with a rotating shaft 5 rotatably connected to the shaft sleeve 14, an adapter sleeve 10 is sleeved on the end of the operating shaft of the circuit breaker trolley 11, a connecting shaft 7 respectively fixed to the adapter sleeve 10 and the rotating shaft 5 is provided between the shaft sleeve 14 and the circuit breaker trolley 11, and the rotating shaft 5, the connecting shaft 7, the adapter sleeve 10 and the operating shaft of the circuit breaker trolley 11 are coaxial.

[0020] By providing a sheath 3 on the side wall of the door panel 4 away from the adapter sleeve 10, and the rotating shaft 5 and the sleeve 14 are both located on the inner side of the sheath 3, the sheath 3 can be used to protect the rotating shaft 5 and the sleeve 14 to prevent the rotating shaft 5 located on the outer side of the door panel 4 from bending and deforming due to accidents. A positioning groove 13 adapted to the rotating shaft 5 is provided on the end face of the connecting shaft 7 close to the door panel 4, and a connecting groove 12 is provided on the end face of the adapter sleeve 10 away from the circuit breaker operating shaft, a first threaded rod 6 is provided on the outer wall of the connecting shaft 7, and the connecting shaft 7 and the rotating shaft 5 are fixedly connected by the first threaded rod 6 extending into the positioning groove 13 in the rotating shaft 5, a connecting rod 9 adapted to the connecting groove 12 is provided on the end face of the connecting shaft 7 away from the door panel 4, and a second threaded rod 8 is provided on the outer wall of the adapter sleeve 10, and the connecting rod 9 and the adapter sleeve 10 are fixedly connected by the second threaded rod 8 of the connecting rod 9 passing through the connecting groove 12, so that the stability of the device during use can be improved and the structure of the device can be prevented from being detached during use. By coaxially arranging the sleeve 3, the rotating shaft 5 and the sleeve 14, it is convenient for the staff to rotate the rotating shaft 5 in the sleeve 3. By respectively opening a first countersunk hole 1 and a second countersunk hole 2 which are compatible with the first threaded rod 6 and the second threaded rod 8 on the outer side walls of the connecting shaft 7 and the adapter sleeve 10, and the first threaded rod 6 and the second threaded rod 8 are respectively located on the inner sides of the first countersunk hole 1 and the second countersunk hole 2, it is possible to prevent the first threaded rod 6 and the second threaded rod 8 from scratching against other circuits during the rotation of the device, thereby affecting the normal use of the device. By arranging a limit rod and a rotating rod at the end of the rotating shaft 5 located in the sleeve 3, and fixing the limit rod on the rotating shaft 5, and the rotating rod extending to the outside of the sleeve 3 in the direction away from the door panel 4, a handle is fixed to the end of the rotating rod away from the door panel 4, and a limit groove is provided on the end face of the rotating rod facing the door panel 4, and the limit rod is inserted into the limit groove. The handle and the rotating rod can not only facilitate the staff to drive the rotating rod to drive the rotating shaft 5 to rotate in the sleeve 14, but also can pull the rotating rod out from the limit rod to disengage the rotating rod from the limit rod, so as to remove the rotating rod from the sleeve 3, thereby preventing the device from accidentally touching the handle and the rotating rod during use, causing damage to the rotating shaft 5, thereby affecting the normal use of the device. Because the adapter sleeve 10 is sleeved on the end of the operating shaft of the circuit breaker trolley 11, when the door panel 4 is opened, the adapter sleeve 10 can move with the door panel 4 and make the end of the operating shaft of the circuit breaker trolley 11 escape from the adapter sleeve 10, and after the door panel 4 is closed, the end of the operating shaft of the circuit breaker trolley 11 is reinserted into the adapter sleeve 10.

[0021] Combined with Figure 1-3It can be seen that the method of using the utility model is as follows: first, when the device needs to be powered on or powered off, the rotating rod needs to be extended into the sleeve 3, and the limiting rod on the rotating shaft 5 is inserted into the limiting groove of the rotating rod, so that the handle is located on the side of the sleeve 3 away from the door panel 4, and then the handle is rotated to drive the rotating rod through the limiting rod to drive the rotating shaft 5, so that the rotating shaft 5 rotates in the sleeve 14, and drives the connecting shaft 7 fixed thereto to rotate, thereby driving the operating shaft on the circuit breaker to rotate, so that the circuit breaker moves forward or backward, so as to realize power supply or power off of the equipment. After the power supply or power off is completed, the rotating rod is pulled out from the limiting rod to disengage the rotating rod from the limiting rod, so as to remove the rotating rod from the sleeve 3.
