Description

Technical Field

[0001] The utility model belongs to the technical field of mobile substations, in particular to a mobile emergency box-type substation. Background Art

[0002] Compared with immovable substations, movable substations are more flexible and can be used in emergencies, such as in outdoor emergency power supply places. In order to facilitate the substation to pass through bumpy roads, existing solutions, such as patent application No. 202220124196.5, discloses a mobile box-type substation, including a substation body, a fixed frame, a screw rod, a locking universal wheel and an L-shaped connecting rod, etc. Through the design of structures such as a rotating shaft, a rotating wheel, a screw rod, an L-shaped connecting rod and a locking universal wheel, the rotating wheel is used to drive the rotating shaft to rotate, and the rotating shaft drives the screw rod to rotate, so that the screw rod seat of the screw rod can move on the screw rod. When the screw rod seat moves downward, the L-shaped connecting rod is driven to move downward, thereby driving the locking universal wheel to move downward, which is used to adjust the distance between the locking universal wheel and the bottom of the substation body. When encountering a relatively bumpy road surface, it is convenient to move the substation body, which is very convenient to use.

[0003] However, in actual use, the above-disclosed technical solution still has the defect of inconvenience: first, there is a fixed frame blocking the top of the locking universal wheel, which requires people to bend over or squat to observe the height adjustment of the locking universal wheel and the road condition on which the locking universal wheel is located. The inconvenience in observation will prolong the time required for adjusting the locking universal wheel and reduce the mobility of the substation body. Secondly, each locking universal wheel is in a state of inconsistent height after passing through a bumpy road surface, and it is inconvenient to adjust the height of all the locking universal wheels to be consistent, causing the substation body to be easily tilted. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the utility model provides a mobile emergency box-type substation. After optimizing the position of the locking universal wheel, the locking universal wheel will not be blocked by the fixed frame. The personnel only need to lower their heads to observe the height adjustment of the locking universal wheel and the road condition where the locking universal wheel is located, without bending over or squatting, thereby reducing the time required for adjusting the locking universal wheel and improving the mobility of the substation body. In addition, the height of the locking universal wheel can be intuitively observed through the indicator arrows and the scale plate. After passing through a bumpy road, it is convenient to adjust the height of all the locking universal wheels to be consistent, thereby avoiding the phenomenon that the substation body is easily tilted.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The mobile emergency box-type substation comprises a substation body, a supporting foot is installed at the lower end of the substation body, a fixed frame is installed on both sides of the substation body, the top of the fixed frame is rotatably connected with a rotating shaft through a bearing, the inside of the fixed frame is rotatably connected with a screw rod, one end of the rotating shaft is fixedly connected to the top of the screw rod through a coupling, an L-shaped connecting rod is fixedly connected to the screw rod seat of the screw rod, a locking universal wheel is installed at the bottom end of the L-shaped connecting rod, the locking universal wheel is located below the side of the fixed frame, a sliding groove is provided on the side of the fixed frame away from the substation body, the L-shaped connecting rod penetrates the sliding groove and is fixedly sleeved with a sliding block slidably connected to the sliding groove, a scale plate is fixedly connected to the side of the fixed frame away from the substation body, scale lines are provided on the scale plate, and an indication arrow located at the scale plate is fixedly sleeved on the L-shaped connecting rod.

[0007] Furthermore, the support leg includes a stud and a pad, the bottom of the substation body is fixedly connected with the stud, and the outer side of the stud is threadedly connected with the pad.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] 1. After optimizing the position of the locking universal wheel, the locking universal wheel will not be blocked by the fixed frame. The personnel only need to lower their heads to observe the height adjustment of the locking universal wheel and the road conditions where the locking universal wheel is located, without bending or squatting, thereby reducing the time required for adjusting the locking universal wheel and improving the mobility efficiency of the substation body.

Example

[0016] See attached Figure 1-2 As shown, the mobile emergency box-type substation includes a substation body 1, a support leg 2 is installed at the lower end of the substation body 1, a fixed frame 3 is installed on both sides of the substation body 1, the top of the fixed frame 3 is rotatably connected with a rotating shaft 4 through a bearing, the inside of the fixed frame 3 is rotatably connected with a screw rod 5, one end of the rotating shaft 4 is fixedly connected to the top of the screw rod 5 through a coupling, an L-shaped connecting rod 6 is fixedly connected to the screw rod seat of the screw rod 5, a locking universal wheel 7 is installed at the bottom end of the L-shaped connecting rod 6, and the locking universal wheel 7 is located below the side of the fixed frame 3, a sliding groove 8 is opened on the side of the fixed frame 3 away from the substation body 1, the L-shaped connecting rod 6 penetrates the sliding groove 8 and is fixedly sleeved with a slider 9 slidably connected to the sliding groove 8, a scale plate 10 is fixedly connected to the side of the fixed frame 3 away from the substation body 1, scale lines are opened on the scale plate 10, and an indication arrow 11 located at the scale plate 10 is fixedly sleeved on the L-shaped connecting rod 6.

[0017] The support leg 2 includes a stud 21 and a pad 22 . The bottom of the transformer substation body 1 is fixedly connected with the stud 21 , and the outer side of the stud 21 is threadedly connected with the pad 22 .

[0018] Working principle: In the utility model, when the transformer substation body 1 passes through a pothole road, the personnel are at the locking universal wheel 7 where the height needs to be adjusted. By lowering their heads, they can see the potholes of the locking universal wheel 7 and the road where the locking universal wheel 7 is located. By rotating the rotating shaft 4 at the locking universal wheel 7, the screw rod 5 can be driven to rotate. The L-shaped connecting rod 6 is rotated by the slider 9 to move upward or downward along with the screw rod 5, and then the locking universal wheel 7 is adjusted in height synchronously with the L-shaped connecting rod 6. At the same time, the L-shaped connecting rod 6 drives the indicating arrow 11 to move, and then when passing through the potholes, the locking universal wheel 7 can be adjusted in height synchronously with the L-shaped connecting rod 6. After the substation body 1 is on the road surface, the corresponding scale line on the scale plate 10 where the indicator arrow 11 is located can be observed to know the height of each locking universal wheel 7. Finally, the heights are adjusted to be consistent, and the substation body 1 is in a horizontal state. When the substation body 1 is placed for emergency use on a bumpy road surface, if there are potholes in the area directly below the support leg 2, the pad 22 can be screwed in advance to increase the distance between the pad 22 and the substation body 1, and then each locking universal wheel 7 is moved upward until each pad 22 abuts against the ground, and the substation body 1 can be stably placed.
