Description

Technical Field

[0001] The present invention relates to the technical field of power grid maintenance, and more specifically, to an operation and maintenance control device for a power distribution network. Background Art

[0002] The distribution network refers to the power grid that receives electric energy from the transmission network or regional power plants and distributes it locally or step by step according to the voltage to various users through distribution facilities. It is composed of overhead lines, cables, towers, distribution transformers, disconnectors, reactive power compensators and some ancillary facilities. It plays an important role in distributing electric energy in the power grid. At present, when the distribution network is in operation, in order to ensure the stable power transmission of the power system, the staff needs to regularly use the distribution network operation detection device to detect and maintain the distribution network, so that the distribution network can be repaired in time when a problem occurs.

[0003] After searching, it was found that the announcement number is CN221631560U, which is an operation detection device for a power system distribution network. The operation detection device can be fixed above the cable of the distribution network. When the staff conducts operation detection on the distribution network, they only need to pull the device to move the device. The device moves on the surface of the cable, so that the staff can quickly detect multiple areas, effectively improving the detection efficiency of the device.

[0004] However, when the operation detection device slides on the cable surface, the entire weight of the operation detection device is pressed on the cable, which may cause damage to the cable, and in severe cases may cause the cable to break, reducing the service life of the cable, and at the same time, causing safety hazards to the staff during the detection process. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an operation and inspection control device for an electric power distribution network. After the upper clamping part and the lower clamping part clamp the cable, the stop valve on the helium cylinder is opened, so that the helium in the helium cylinder inflates the helium balloon through the hose. The inflated helium balloon rises due to the buoyancy and pulls up the operation and inspection control device, reducing the pressure of the operation and inspection control device on the cable and avoiding damage to the cable.

[0035] Working principle of the first embodiment:

[0036] After the upper clamping part 4 and the lower clamping part 5 complete the clamping of the cable, the stop valve 24 on the helium cylinder 6 is opened, so that the helium in the helium cylinder 6 inflates the helium balloon 12 through the hose 10. The inflated helium balloon 12 rises due to the buoyancy and pulls up the operation and inspection control device 1, reducing the pressure of the operation and inspection control device 1 on the cable and avoiding damage to the cable. At the same time, the friction between the upper clamping part 4 and the cable is reduced, which facilitates the movement of the operation and inspection control device 1 and improves the detection efficiency.

[0039] The first handles 25 are symmetrically fixed on the two opposite sides of the operation and inspection control equipment body 2; the tool storage boxes 26 are fixedly installed on the two opposite sides of the operation and inspection control equipment body 2 below the corresponding first handles 25; the inner wall of the tool storage box 26 is provided with a slide groove 27; an L-shaped baffle 28 is slidably arranged between the inner walls of the slide groove 27; a return spring 29 is fixedly connected between the L-shaped baffle 28 and the tool storage box 26; and a second handle 30 is fixed on the side of the L-shaped baffle 28.

[0040] Working principle of the second embodiment:

[0041] In the initial state, the third fur layer 21 on the side of the uninflated helium balloon 12 is bonded to the third hook surface layer 22; the helium cylinder 6 is placed in the placement cavity 7, and the first fur layer 18 on the side of the helium cylinder 6 is bonded to the first hook surface layer 17 on the inner wall of the placement cavity 7, thereby improving the stability of the helium cylinder 6, and the strap 19 is tied to the helium cylinder 6, and the second hook surface layer on the side of the strap 19 is bonded to the first fur layer 18 on the side of the helium cylinder 6, and then the end of the strap 19 is bonded to the second fur layer 20, thereby completing the tightening of the helium cylinder 6 and further improving the stability of the helium cylinder 6.

[0042] The first connecting tube 9 is screwed to the gas supply pipe 8, the second connecting tube 11 is screwed to the connecting tube 13, and the connection between the helium cylinder 6 and the helium balloon 12 is completed through the hose 10; after the upper clamping part 4 and the lower clamping part 5 clamp the cable, the stop valve 24 on the helium cylinder 6 is opened. At this time, the stop valve 24 on the ear tube 23 is closed, so that the helium in the helium cylinder 6 inflates the helium balloon 12 through the hose 10. The inflated helium balloon 12 rises due to the buoyancy, and each group of connecting ropes 16 is tightened, thereby pulling up the operation and inspection control device 1, reducing the pressure of the operation and inspection control device 1 on the cable.

[0043] The maintenance tool is placed in the tool storage box 26, and the L-shaped baffle 28 is driven to slide along the slide groove 27 under the elastic force of the return spring 29 to block the top of the tool storage box 26. During maintenance, the second handle 30 is pulled outward to make the L-shaped baffle 28 slide out and the maintenance tool can be taken out, thereby improving the practicality of the device.

[0044] For example 3, please refer to Figure 1-10 The third embodiment of the present invention makes the following improvements on the basis of the second embodiment. Specifically, a bidirectional screw rod 31 is rotatably arranged between the inner walls of the two L-shaped support plates 3; a first annular handle 32 is fixed to one end of the bidirectional screw rod 31; guide plates 33 are symmetrically fixed on both sides of the bidirectional screw rod 31 between the inner walls of the two L-shaped support plates 3; the upper clamping part 4 includes a slide plate 34; limiting grooves 54 that are symmetrically arranged on the top of the slide plate 34 and are slidably matched with the guide plate 33; a first screw hole 35 that is threadably matched with the bidirectional screw rod 31 is arranged on the side of the slide plate 34 between the two limiting grooves 54.

[0045] Vertical plates 36 are symmetrically fixed to the bottom of the slide plate 34; an upper guide wheel 37 is evenly rotatably arranged between the two vertical plates 36; a screw rod 38 is rotatably arranged on the bottom surface of one vertical plate 36; a second annular handle 39 is fixed to the bottom end of the screw rod 38; sliding rods 40 are symmetrically fixed to the bottom surface of the vertical plates 36 on both sides of the screw rod 38; a stopper 41 is fixed to the bottom end of the sliding rod 40.

[0046] The lower clamping portion 5 includes two connecting plates 42 arranged parallel to each other; a plurality of connecting shafts 43 are evenly fixed between the two connecting plates 42; a lower guide wheel 44 is rotatably arranged on the connecting shaft 43; a second screw hole 45 is opened on the surface of one connecting plate 42 to rotate with the screw rod 38; sliding holes 46 are symmetrically opened on the surface of the connecting plate 42 on both sides of the second screw hole 45 to slide with the sliding rod 40.

[0047] A sleeve 47 is fixed to the side of the connecting plate 42; an annular groove 48 is provided on the inner wall of the sleeve 47; a rotating portion 49 is rotatably provided in the sleeve 47; the rotating portion 49 includes a rotating rod 50 rotatably provided in the sleeve 47; an annular rail 51 rotatably matched with the annular groove 48 is fixed to the circumferential side of the rotating rod 50; an L-shaped rod 52 is fixed to the end of the rotating rod 50; a socket 53 which is plugged and matched with the L-shaped rod 52 is provided on the bottom surface of the L-shaped support plate 3.

[0048] Working principle of the third embodiment:

[0049] The transport and inspection control device 1 is placed above two parallel cables to be tested. At this time, the L-shaped rod 52 is downward and perpendicular to the cable. The first annular handle 32 is rotated to drive the reciprocating screw rod 31 to rotate, thereby driving the two groups of upper clamping parts 4 to slide away synchronously along the guide plate 33 until the cable is located between the upper clamping part 4 and the lower clamping part 5. The second annular handle 39 is rotated to drive the screw rod 38 to rotate, so that the corresponding lower clamping part 5 moves in the direction close to the corresponding upper clamping part 4. During the rising process of the lower clamping part 5, the L-shaped rod 52 is rotated to align it upward with the socket 53, so that the cable is clamped between the upper guide wheel 37 and the lower guide wheel 44. At this time, the L-shaped rod 52 is inserted into the socket 53, which improves the stability of the lower clamping part 5 and prevents the cable from sliding from the upper guide wheel 37 and After slipping between the lower guide wheels 44, the transportation and inspection control device 1 falls, which plays a role in preventing it from falling; after completing the clamping of the cable by the upper clamping part 4 and the lower clamping part 5, the transportation and inspection control device 1 can slide freely along the cable to achieve rapid clamping of two parallel cables at different distances, and the transportation and inspection control device 1 can slide freely between the two parallel cables, so that the staff can quickly inspect multiple areas, effectively improving the inspection efficiency; when it is necessary to stop the transportation and inspection control device 1 for inspection, the second annular handle 39 is rotated to drive the screw 38 to rotate, so that the lower clamping part 5 continues to move upward to complete the clamping of the cable. After completing the inspection, the screw 38 is rotated in the opposite direction to reset it to the clamping state, that is, the transportation and inspection control device 1 can slide freely between the two parallel cables.
