Description

Technical Field

[0001] The utility model relates to the technical field of power maintenance, in particular to a power supply connection device for power transformation maintenance. Background Art

[0002] Substation maintenance is a key link in ensuring the stable operation of the power system. The substation maintenance power connection device is a set of equipment designed specifically for substation system maintenance. When power station workers are working outside, they often need to draw power from wires near the construction site. The traditional practice is to first cut off the power in the construction area, and then the workers climb up the utility poles to connect the wires. The power connection device can directly connect the bare wires.

[0003] Although the power supply connection device in the prior art has many benefits during use, it still has the following problems: its protection for the safety of electrical connections is not perfect, which leads to the phenomenon of creepage in the bare wires when it rains in the use environment. Therefore, when the staff dismantle the equipment in a rainy environment, the rain covers the surface of the equipment, and the rain causes the contact area between the bare wire and the guide block to become larger, so the current will be transmitted along the flow surface of the rain, affecting the safety of the staff in dismantling the equipment. Utility Model Content

[0004] In view of the problems in the prior art, the utility model provides a power supply connection device for power transformation maintenance.

[0005] The technical solution adopted by the utility model to solve its technical problems is a substation maintenance power supply connection device, including a fixed plate, a connecting rod, an air inlet cover and a connecting cover, the connecting rod is movably installed on the inner wall of the fixed plate, the connecting cover is installed on the outer wall of the upper end of the connecting rod, a clamping block is installed on the outer wall of the upper end of the connecting cover, a vent hole is opened inside the clamping block, a support block is installed on one side of the inner wall of the connecting cover, and a conductive plate is installed on the outer wall of the upper end of the support block.

[0006] By adopting the above technical solution, the clamping plate clamps and fixes the bare wire, and the conductive plate transmits the current of the bare wire, and the air flow can be discharged through the vent hole.

[0007] Specifically, a spring is provided on one side of the outer wall of the connecting rod, the spring is located at the upper end of the fixing plate, and the connecting cover is elastically connected to the fixing plate through the spring.

[0008] By adopting the above technical solution, the spring force pushes the connection cover to maintain the stability of the connection cover's use position, and the clamping block cooperates with the buckle to clamp and fix the bare wire, maintaining the stability of the position of the fixing plate outside the bare wire.

[0009] Specifically, a support rod is installed on one side of the outer wall of the lower end of the fixing plate, and the connecting rod is located inside the support rod.

[0010] By adopting the above technical solution, the staff can adjust the use length of the connecting rod and the support rod by themselves during actual use, ensuring that when the staff lifts the support rod, the fixing plate can be located outside the bare wire and the connecting rod can move inside the support rod.

[0011] Specifically, an extension plate is installed on one side of the outer wall of the upper end of the fixing plate, and a buckle is installed on the outer wall of the upper end of the extension plate. The buckle is located at the upper end of the connecting cover.

[0012] By adopting the above technical solution, the extension plate raises the use position of the buckle, and the buckle can block the upper end of the connection cover, so that when the clamping block squeezes the bare wire, the buckle cooperates to squeeze and fix the bare wire.

[0013] Specifically, a conductive column is embedded in the support block and connected to the conductive plate. An electric wire is provided on one side of the lower end of the inner wall of the connecting rod, and the outer wall of the upper end of the electric wire is connected to the outer wall of the lower end of the conductive column.

[0014] By adopting the above technical solution, the conductive plate contacts the outer surface of the bare wire, so that the current inside the bare wire can be transmitted through the conductive column, and the current can be connected through the wire to meet the power supply needs of external equipment.

[0015] Specifically, the support block and the conductive plate are both located inside the vent hole, and the curvature of the inner wall of the conductive plate matches the curvature of the inner wall of the clamping block.

[0016] By adopting the above technical solution, the gas inside the connection cover flows out through the gap between the support block and the vent, thereby forming an air curtain outside the contact surface between the conductive plate and the bare wire, preventing the connection position from being affected by rain and improving the safety of the connection.

[0017] Specifically, an air inlet cover is installed on the outer wall of the lower end of the connecting rod, and the air inlet cover is located at the lower end of the support rod. A fan body is installed on one side of the inner wall of the air inlet cover. The air inlet cover, connecting rod, connecting cover and vent are connected to each other.

[0018] By adopting the above technical solution, the air flow driven by the fan body can flow into the interior of the connecting cover through the air inlet cover and the connecting rod, and the gas inside the connecting cover is discharged through the vent hole.

[0019] Beneficial effects of the utility model:

[0020] (1) The utility model describes a substation maintenance power supply connection device, in which the spring force pushes the connection cover to reset, so that the clamping block clamps the bare wire, ensuring the position stability of the bare wire between the buckle and the clamping block, achieving the purpose of fixing the conductive plate and ensuring the contact stability between the conductive plate and the bare wire. Afterwards, the current of the bare wire is connected through the conductive plate and the conductive column, and the current is transmitted to the inside of the external device through the wire, achieving the purpose of power induction.

[0021] (2) In the utility model, a substation maintenance power supply connection device is described. External gas enters the air inlet hood through the air inlet hood and the connecting rod, and is discharged through the vents, thereby achieving the purpose of forming an air curtain on the outside of the contact point between the conductive plate and the bare wire. The air curtain shields and protects the contact point between the conductive plate and the bare wire, preventing rain from causing the contact surface between the bare wire and the guide plate to increase, and preventing the current from being transmitted along the flow surface of rainwater, thereby improving the safety of the equipment and helping staff to disassemble the equipment during rainfall.

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0029] In order to save manpower and improve efficiency, as an embodiment of the present invention, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown, the utility model describes a substation maintenance power supply connection device, comprising a fixed plate 1, a connecting rod 2, an air inlet cover 3 and a connecting cover 22. The connecting rod 2 is movably mounted on the inner wall of the fixed plate 1, the connecting cover 22 is mounted on the upper outer wall of the connecting rod 2, a clamping block 23 is mounted on the upper outer wall of the connecting cover 22, a vent 24 is provided inside the clamping block 23, a support block 25 is mounted on one side of the inner wall of the connecting cover 22, and a conductive plate 26 is mounted on the upper outer wall of the support block 25.

[0030] When in use, the clamping block 23 clamps and fixes the bare wire, and the conductive plate 26 transmits the current of the bare wire, and the air flow can be discharged through the vent hole 24.

[0031] In order to maintain the clamping force on the bare wire, for example, Figure 3 As shown, a spring 21 is provided on one side of the outer wall of the connecting rod 2 , the spring 21 is located at the upper end of the fixing plate 1 , and the connecting cover 22 is elastically connected to the fixing plate 1 through the spring 21 .

[0032] When in use, the spring 21 pushes the connecting cover 22 to maintain the stability of the connecting cover 22 in use position, and the clamping block 23 cooperates with the buckle 13 to clamp and fix the bare wire, maintaining the position stability of the fixing plate 1 outside the bare wire.

[0033] In order to raise the fixing plate 1, for example, Figure 2 As shown, a support rod 11 is installed on one side of the outer wall of the lower end of the fixing plate 1, and the connecting rod 2 is located inside the support rod 11.

[0034] During use, the staff can adjust the use length of the connecting rod 2 and the support rod 11 by themselves during actual use to ensure that when the staff lifts the support rod 11, the fixing plate 1 can be located outside the bare wire and the connecting rod 2 can move inside the support rod 11.

[0035] To fix the bare wire, for example, Figure 2 As shown, an extension plate 12 is installed on one side of the outer wall of the upper end of the fixing plate 1 , and a buckle 13 is installed on the outer wall of the upper end of the extension plate 12 . The buckle 13 is located at the upper end of the connecting cover 22 .

[0036] When in use, the extension plate 12 raises the use position of the buckle 13, and the buckle 13 can cover the upper end of the connection cover 22, so that when the clamping block 23 squeezes the bare wire, the buckle 13 cooperates to squeeze and fix the bare wire.

[0037] To connect electricity, for example, Figure 3 As shown, a conductive column 27 is embedded in the support block 25 and connected to the conductive plate 26. A wire 28 is provided on one side of the lower end of the inner wall of the connecting rod 2, and the outer wall of the upper end of the wire 28 is connected to the outer wall of the lower end of the conductive column 27.

[0038] When in use, the conductive plate 26 contacts the outer surface of the bare wire, so that the current inside the bare wire can be transmitted through the conductive column 27, and the current can be connected to the wire 28 to meet the power supply needs of external equipment.

[0039] To form an air curtain, for example, Figure 3 As shown, the support block 25 and the conductive plate 26 are both located inside the vent hole 24 , and the curvature of the inner wall of the conductive plate 26 matches the curvature of the inner wall of the clamping block 23 .

[0040] When in use, the gas inside the connection cover 22 flows out through the gap between the support block 25 and the vent hole 24, thereby forming an air curtain outside the contact surface between the conductive plate 26 and the bare wire, preventing the connection position from being affected by rain and improving the safety of the connection.

[0041] For air supply, for example, Figure 4 As shown, an air inlet cover 3 is installed on the outer wall of the lower end of the connecting rod 2, and the air inlet cover 3 is located at the lower end of the support rod 11. A fan body 31 is installed on one side of the inner wall of the air inlet cover 3. The air inlet cover 3, the connecting rod 2, the connecting cover 22 and the vent 24 are internally connected.

[0042] When in use, the air flow driven by the fan body 31 can flow into the interior of the connecting cover 22 through the air inlet cover 3 and the connecting rod 2 , and the gas inside the connecting cover 22 is discharged through the vent hole 24 .

[0043] When the utility model is in use, the staff holds the support rod 11 and lifts the fixing plate 1 to move the fixing plate 1 to the outside of the bare wire. The staff manually pulls the connecting rod 2 to move the connecting cover 22 vertically toward the fixing plate 1, thereby creating a gap between the clamping block 23 and the buckle 13. The staff then moves the clamping block 23 and the buckle 13 to the upper and lower sides of the bare wire through the gap.

[0044] When the staff releases the pulling force on the connecting rod 2, the spring 21 pushes the connecting cover 22 back to its original position, so that the clamping block 23 clamps the bare wire, ensuring the position stability of the bare wire between the buckle 13 and the clamping block 23;

[0045] The current of the bare wire is connected through the conductive plate 26 and the conductive column 27, and the current is transmitted to the inside of the external device through the wire 28.

[0046] After the power connection is completed as described above, the current is supplied to the fan body 31 to provide power, so that the fan body 31 works, and the air is driven to flow through the fan blades of the fan body 31, so that the external gas enters the air inlet cover 3 through the air inlet cover 3 and the connecting rod 2, and is discharged through the vent 24, thereby achieving the purpose of forming an air curtain on the outside of the contact point between the conductive plate 26 and the bare wire, and the air curtain shields and protects the contact point between the conductive plate 26 and the bare wire.
