[0002] Substation operation and maintenance refers to the daily operation, maintenance, fault handling, and switching operations of substations and their equipment. Substation operation and maintenance work includes equipment inspection and fault handling. When handling faults, staff need to use various instruments to detect substation equipment and use cables to handle faults in order to quickly restore power supply to non-faulty areas and reduce power outage losses.

[0003] Currently, in substation operation and maintenance, to save physical effort, workers can use handcarts to transport instruments and cables of a certain weight to the work site for subsequent maintenance and repair. However, some handcarts have a large exposed area in the external space. When transporting some instruments, the bumps caused by the ground can affect the stability of the instrument during transport. In addition, some cables are prone to shifting or even falling off during transport due to bumps. Once the cables fall off, they become loose and can affect their subsequent use.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-7 As shown, a folding handcart suitable for substation operation and maintenance includes a handcart body 1. The surface of the handcart body 1 is equipped with a handle, which is an existing mature technology and will not be described in detail here. A hollow frame 2 is fixedly connected to the top of the handcart body 1. A protective cloth 3 is fixedly connected to the inner wall of the hollow frame 2. One side of the protective cloth 3 is fixedly connected to the inner wall of the hollow frame 2. A connecting plate 4 is fixedly connected to the other side of the protective cloth 3. A positioning mechanism 5 is provided on the top of the connecting plate 4. A positioning groove is opened on the top of the handcart body 1. The positioning mechanism 5 cooperates with the positioning groove to restrict the position of the connecting plate 4. A rectangular plate 7 is embedded in the top of the handcart body 1. Storage grooves are opened on both sides of the top of the rectangular plate 7. A support mechanism 8 and a pressing mechanism 9 are provided inside the storage grooves. When the support mechanism 8 is unfolded, it can limit the cable for subsequent use. The pressing mechanism 9 can restrict the state of the support mechanism 8.

[0025] The positioning mechanism 5 includes a force-bearing rod 51, a lifting plate 52, a positioning rod 53, and a compression spring 54. The two ends of the force-bearing rod 51 slide through the top of the connecting plate 4 on both sides. A cavity is opened inside the connecting plate 4. The surface of the lifting plate 52 is slidably connected to the inner wall of the cavity. The bottom of the force-bearing rod 51 is fixedly connected to the top of the lifting plate 52. The positioning rod 53 is fixedly connected to the bottom of the lifting plate 52 and slides through the bottom of the connecting plate 4. The compression spring 54 is set inside the cavity. The two ends of the compression spring 54 are fixedly connected to the top of the lifting plate 52 and the top of the inner wall of the cavity, respectively. When the operator pulls the force-bearing rod 51, the lifting plate 52 is raised. The surface of the positioning rod 53 contacts the inner wall of the positioning groove. At this time, the contact between the positioning rod 53 and the positioning groove on one side is released. The operator can then pull the force-bearing rod 51 to move the connecting plate 4 so as to unfold the protective cloth 3. Afterwards, under the elastic force of the compression spring 54, the lifting plate 52 drives the positioning rod 53 to descend. The positioning rod 53 cooperates with the positioning groove on the other side to fix the position of the connecting plate 4.

[0026] The unfolded protective cloth 3 is as shown in Figure 2, so as to cover and protect the instruments or cables placed on the trolley body 1 and the top of the rectangular plate 7, and reduce the possibility of the instruments falling off due to bumps during transportation.

[0027] The bottom of the force-bearing rod 51 is fixedly connected to the limiting rod 6, and the top of the hollow frame 2 is provided with a slot. The surface of the limiting rod 6 contacts the inner wall of the slot. The position of the force-bearing rod 51 can be restricted by the cooperation of the limiting rod 6 and the slot, so as to increase the stability of the protective cloth 3 when folded and stored inside the hollow frame 2.

[0028] The support mechanism 8 includes a rotating shaft 81, a collar 82, and a support rod 83. The rotating shaft 81 is installed on both sides of the inner wall of the storage slot via a spring hinge. The collar 82 is fixedly sleeved on the surface of the rotating shaft 81. One end of the support rod 83 is fixedly connected to the surface of the collar 82. When the operator rotates the support rod 83, the rotating shaft 81 can make the support rod 83 stand upright through the collar 82 under the action of the spring hinge. At this time, the operator can put the cable loop on the surface of the support rod 83 for later use. The operator places the support rod 83 in the storage slot. The top of the support rod 83 is flush with the top of the rectangular plate 7 so that the operator can place the maintenance instruments on the top of the trolley body 1 and the rectangular plate 7.

[0029] The storage tank has sliding grooves on both sides of its inner wall. The pressing mechanism 9 includes a smooth rod 91, a slider 92, and a pressure plate 93. The two ends of the smooth rod 91 are fixedly connected to the two sides of the inner wall of the sliding groove, respectively. The slider 92 is slidably sleeved on the surface of the smooth rod 91 and contacts the inner wall of the sliding groove. The surface of the pressure plate 93 is slidably connected to the inner wall of the storage tank. The slider 92 is fixedly connected to the pressure plate 93. The bottom of the pressure plate 93 contacts the surface of the support rod 83. The pressure plate 93 and the support rod 83 cooperate to restrict the position of the support rod 83, thereby increasing the stability of the support rod 83. This allows the staff to stably place the instrument on top of the trolley body 1 and the rectangular plate 7 for subsequent maintenance operations.

[0030] A slot 10 is provided at the bottom of the inner wall of the chute. Baffles 11 are fixed on both sides of the inner wall of the slot 10. A spring piece 12 is provided inside the slot 10. The bottom of the spring piece 12 contacts the bottom of the inner wall of the slot 10, and the bottom of the slider 92 contacts the top of the spring piece 12. When the operator moves the pressure plate 93, the slider 92 moves accordingly. At this time, the pressure plate 93 releases the limit on the support rod 83, and the slider 92 presses against the spring piece 12. The baffle 11 restricts the position of the spring piece 12. When the pressure plate 93 restricts the position of the support rod 83, the spring piece 12 restricts the position of the slider 92, which can increase the effect of the pressure plate 93 in limiting the support rod 83.

[0031] Working principle: The staff places the instrument used for operation and maintenance on the top of the handcart body 1 and pulls the force rod 51. The contact between the positioning rod 53 and the positioning groove on one side is released. The staff can then pull the force rod 51 to move the connecting plate 4. The protective cloth 3 can be unfolded to protect the instrument.

[0032] Workers move the pressure plate 93, the support rod 83 is erected, and the cable loop is placed on the surface of the support rod 83 to limit the cable. Workers can transport the instrument or cable to the work point by moving the handcart body 1. After that, workers can use the instrument or pull one end of the cable to repair the substation fault.
