Description

Technical Field

[0001] The present invention relates to the technical field of live transmission line operations, and in particular to a 35kV bypass operation vehicle and an operation method. Background Art

[0002] The bypass operation vehicle is a vehicle specially used for the inspection, maintenance and troubleshooting of power equipment. It can provide necessary protection and convenience for power maintenance personnel while ensuring the normal operation of the power system. When the power grid lines are being modified and repaired, by using the bypass operation vehicle, bypass drainage lines, bypass flexible cables and other equipment are combined in a building block-like manner to form a bypass channel, thereby ensuring that the power supply line will not affect the continuous power supply to users during the power outage maintenance process. It is an important means to reduce power outage time.

[0003] For example, CN114865531A involves a 0.4kV power distribution bypass operation vehicle and an operation method, which include a vehicle chassis, a power distribution cabinet and a cable reel installed on the vehicle chassis, a bypass switch box provided in the power distribution cabinet, and a portable operation reel that can be taken and placed on the vehicle chassis. Quick-plug connectors are provided at the inlet and outlet interfaces of the bypass switch box. The portable operation reel is used to store three types of connecting cables, namely, a first connecting cable with overhead line drainage clamps and quick-plug connectors at both ends, a second connecting cable with a busbar clamp and a quick-plug connector at both ends, and a third connecting cable with copper terminals and quick-plug connectors at both ends. The cable reel is used to store transmission cables, and both ends of the transmission cables have connector terminals that match the quick-plug connectors.

[0004] The above-mentioned bypass operation vehicle and operation method simplify the operation process, improve the efficiency of bypass live operation, and reduce the labor intensity of operators, but do not explain how to control the retraction and release of bypass cables when the bypass operation is applied to overhead cables.

[0041] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

The overhead fixed body is used to fix the overhead cable, and the bypass fixed body is used to fix the other end of the bypass cable. The lifting structure 21 drives the overhead fixed body to move upward. When the overhead fixed body contacts the overhead cable, the overhead fixed body is displaced relative to the lifting structure 21 under the squeezing of the overhead cable, thereby driving the bypass fixed body to pull the bypass cable to be released from the winding structure 13, and through the displacement of the bypass fixed body, the overhead fixed body is driven to clamp and fix the overhead cable.

[0047] The above structure is disclosed as follows:

[0048] During bypass operation, if the bypass cable is released too long, it will cause cable entanglement and other problems, which is inconvenient for the management of the bypass cable. However, if the bypass cable is released too short, it will affect the connection between the bypass cable and the overhead cable, thereby affecting the efficiency of the bypass operation. Figure 3 , Figure 4 , Figure 5 , Figure 6 , Fig.10As shown, the winding structure 13 includes a reel 131 rotatably connected to the inner wall of the shielding box 11, a bypass cable is wound on the reel 131, and one connecting terminal of the bypass cable is connected to the box-type transformer 12, the bypass cable includes a quick-plug power cable terminal, a cap and a high-voltage flexible power cable, the lifting structure 21 includes an outer flat plate 211 and a lifting plate 212 connected to the outer flat plate 211 for sliding up and down, the outer flat plate 211 is fixed to one side of the shielding box 11 on the vehicle body, and a hydraulic body for controlling the upward and downward movement of the lifting plate 212 is arranged at the bottom of the lifting plate 212, the overhead fixed body includes a lower hook 22 and an upper hook 23 slidably connected to the lifting plate 212, the bypass fixed body includes an end fixing piece 24 slidably connected to the lifting plate 212, the end fixing piece 24 is used to fix the other connecting terminal of the bypass cable, the lower hook 22 and the upper hook 23 are connected by transmission through the end fixing piece 24, the lifting structure 21 drives the overhead fixed body to move upward, and when the overhead fixed body contacts the overhead When the cable is being wound, the overhead fixed body is displaced relative to the lifting structure 21 under the pressure of the overhead cable, thereby driving the bypass fixed body to pull the bypass cable to be released from the winding structure 13, and through the displacement of the bypass fixed body, the overhead fixed body is driven to clamp and fix the overhead cable, and the hydraulic body controls the lifting plate 212 to move up along the flat plate 211 outside the box so that the overhead fixed body contacts the overhead cable, and when the lower hook 22 contacts the bottom of the overhead cable, under the pressure of the overhead cable, the lower hook 22 moves down along the lifting plate 212 and drives the end fixing member 24 to move up along the lifting plate 212, and when the end fixing member 24 moves up, it pulls the bypass cable so that the winding structure 13 releases a bypass cable of sufficient length, and through the upward movement of the end fixing member 24, the upper hook 23 is driven to move down close to the top of the overhead cable, and cooperates with the lower hook 22 to clamp and fix the overhead cable up and down, and after fixation, the other connecting terminal of the bypass cable is taken out from the end fixing member 24 and connected with the overhead cable to perform bypass operation.

[0049] The specific structures of the lower hook member 22, the upper hook member 23, and the end fixing member 24 are disclosed below:

[0050] like Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 As shown, the lower hook member 22 includes a first slide plate 221 which is slidably connected to the inner wall of the lifting plate 212 up and down. A lower hook plate 222 is provided at one end of the first slide plate 221. The lower hook plate 222 is a semicircular ring structure. When the lifting plate 212 moves up, the first slide plate 221 on the lifting plate 212 is driven to approach the overhead cable. Fig.11 As shown, when the aerial cable contacts the bottom, the aerial cable can be confined within the semicircular lower hook plate 222 to prevent the aerial cable from sliding off the first slide plate 221 .

[0051] The lifting plate 212 is rotatably connected with a first screw shaft 213 and a second screw shaft 214. The first screw shaft 213 passes through the end of the first slide plate 221 away from the lower hook plate 222 and is connected to the first slide plate 221 screw. The first screw shaft 213 and the second screw shaft 214 are connected by a belt transmission. The end fixing member 24 includes a third slide plate 241 connected to the inner wall of the lifting plate 212 for sliding up and down. The second screw shaft 214 passes through the middle of the third slide plate 241 and is connected to the third slide plate 241 screw. The surface of the third slide plate 241 is provided with a fixing clip 242 for fixing another connecting terminal of the bypass cable. The outer wall of the lifting plate 212 is provided with a fixed pulley 217 for guiding the cable. As the lifting plate 212 continues to move upward, under the extrusion of the overhead cable, Fig.13 As shown by the solid arrow a, the first slide plate 221 slides down along the inner wall of the lifting plate 212, and drives the first screw shaft 213 when sliding down, and then drives the second screw shaft 214 connected to the first screw shaft 213, so that the second screw shaft 214 drives the third slide plate 241 to move up along the inner wall of the lifting plate 212. Fig.13 As shown by the solid arrow b, the third slide plate 241 drags the bypass cable through the fixing clip 242 , so that the bypass cable is rolled out from the reel 131 .

[0052] The upper hook member 23 includes a second slide plate 231 which is slidably connected to the outer wall of the lifting plate 212, an upper hook plate 232 is provided at one end of the second slide plate 231 close to the lower hook plate 222, a third screw shaft 2121 is rotatably connected to the outer wall of the lifting plate 212, one end of the third slide plate 241 passes through the outer wall of the lifting plate 212 and is connected to the third screw shaft 2121 screw, the third screw shaft 2121 passes through the second slide plate 231 and is connected to the second slide plate 231 screw, the upper hook plate 232 is slidably connected to the second slide plate 231, and a plate shaft is provided on the side wall of the upper hook plate 232 233, a displacement groove 2122 is correspondingly opened on the outer wall of the lifting plate 212, and the plate shaft 233 is located in the displacement groove 2122 and is slidably connected to the displacement groove 2122. When the third slide plate 241 moves up along the inner wall of the lifting plate 212, the third screw shaft 2121 connected to the third slide plate 241 screw rotates itself, thereby driving the second slide plate 231 connected to the third screw shaft 2121 screw to move down along the outer wall of the third screw shaft 2121. During the downward movement, the plate shaft 233 of the upper hook plate 232 slides along the displacement groove 2122, as shown in FIG. Fig.13 As shown by the solid arrow c, as the second slide plate 231 moves downward, the upper hook plate 232 moves to the top of the lower hook plate 222, and then moves vertically downward to cooperate with the lower hook plate 222. Fig.12 As shown, the overhead cables are clamped and fixed.

[0053] After the overhead cable is clamped and fixed, it is necessary to remove the part of the overhead cable to be tested, and then connect the bypass cable with the remaining part of the overhead cable to maintain power supply. In order to be able to automatically pop out the other connection terminal of the bypass cable from the fixing clip 242 to reduce the difficulty of operation and simplify the operation process, Figure 6 , Figure 7 , Fig. 9 As shown, the inner wall of the third screw shaft 2121 is slidably connected with an intermediate rod 2123, and the lower hook plate 222 is plugged with a first toggle block 223, and the first toggle block 223 is in sliding contact with the surface of the intermediate rod 2123 away from the lower hook plate 222, and the fixing clip 242 is plugged with a second toggle plate 243, and one end of the second toggle plate 243 is in sliding contact with the surface of the intermediate rod 2123. When the upper hook plate 232 cooperates with the lower hook plate 222 to clamp and fix the overhead cable, the overhead cable is squeezed by the upper hook plate 232 and moves along the groove surface of the lower hook plate 222 to squeeze the first toggle block 223, so that the first toggle block 223 drives the intermediate rod 2123, and then drives the second toggle plate 243 to move through the intermediate rod 2123, so that the second toggle plate 243 can push out the other connecting terminal of the bypass cable in the fixing clip 242, thereby facilitating the operator to directly take the other connecting terminal of the bypass cable and connect it with the rest of the overhead cable.

[0054] After the bypass operation is completed, the device is reset. During this process, the bypass cable released during the previous bypass operation needs to be retracted. Figure 4 , Figure 6 As shown, the reel 131 is embedded with an inner rotating drum 132, and the outer end of the reel 131 is plugged with an outer rotating drum 133. The outer rotating drum 133 and the reel 131 are meshed through a ratchet 1311 arranged on the surface of the reel 131. The outer rotating drum 133 and the inner rotating drum 132 are plugged and matched, and the outer rotating drum 133 is connected to the inner wall of the inner rotating drum 132 through a spring. The bottom of the first screw shaft 213 is snap-fitted with a transmission sleeve 215, and the bottom end of the transmission sleeve 215 is meshed with a driving wheel 216, and the driving wheel 216 is meshed with the outer rotating drum 133 is connected through a belt drive. During the resetting process of the device, the second slide plate 231 is first reset upward, so that the third screw shaft 2121 drives the third slide plate 241, and then drives the first screw shaft 213 to reverse and reset. The first screw shaft 213 then drives the transmission sleeve 215 to rotate, and the driving wheel 216 engaged with the transmission sleeve 215 drives the outer drum 133 through the belt drive, so that the reel 131 engaged with the outer drum 133 reverses to retract the bypass cable, thereby facilitating the control of the bypass circuit.

[0055] The second purpose of this embodiment is to provide a method for the above-described 35kV bypass operation vehicle to perform operations, and the specific steps are as follows:

[0056] S1, move the vehicle to the bottom of the overhead cable until the straight line where the lifting plate 212 is located is on the same vertical plane as the straight line where the overhead cable is located, and then disconnect the power supply of the overhead cable;

[0057] S2, the hydraulic body controls the lifting plate 212 to drive the first slide plate 221 on the lifting plate 212 to approach the bottom of the overhead cable. Under the pressure of the overhead cable, the first slide plate 221 slides down and drives the first screw shaft 213, and then drives the third slide plate 241 to move up and drag the bypass cable;

[0058] S3, as the first slide plate 221 continues to move downward, the third slide plate 241 continues to move upward to drive the second slide plate 231 to move downward, and the upper hook plate 232 moves to the top of the lower hook plate 222, and then moves vertically downward to cooperate with the lower hook plate 222 to clamp and fix the overhead cable;

[0059] S4. After fixing, the other connecting terminal of the bypass cable is taken out from the fixing clip 242 and connected to the overhead cable to perform bypass operation.
