Description

Technical Field

[0001] The present invention relates to the technical field of power cable deicing, and in particular to a power cable anti-icing device. Background Art

[0002] Power cables are conductors used to distribute and transmit electrical energy. When the weather is cold, ice easily forms on the power cables, which can easily break the cables and cause power shortages. Therefore, the ice on the power cables needs to be removed.

[0003] Patent document with publication number CN116488093A discloses a live ice removal device for distribution lines, including a frame and a traveling mechanism arranged on the frame. The frame is also provided with a line clamping mechanism and a knocking deicing mechanism. The line clamping mechanism is provided with a deicing tool. When the line clamping mechanism clamps the line, the distance between the deicing tool and the line is smaller than the distance between the knocking deicing mechanism and the line. The traveling mechanism is started to drive the line clamping mechanism and the knocking deicing mechanism to move along the line. The knocking deicing mechanism is started to knock on the ice farther away from the line, and the deicing tool is moved to remove the ice closer to the line. This structure can knock and shatter the ice above the conductor.

[0004] When in use, existing de-icing equipment usually uses a knocking mechanism to knock off the ice on the outside of the conductor. This method is more effective for accumulated snow or thin ice. When encountering a thicker layer of ice, the knocking force is limited, resulting in poor overall de-icing effect, so that the ice on the surface of the conductor cannot be completely removed.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. When encountering ice, the cutters are arranged in a circle and the installation of the open ring, the limit plate, the limit rod and the resistance spring are coordinated to make the cutters exert pressure on the ice in multiple directions. The operation of the driving wheel drives the cutters to cut the surface of the ice layer, so that the outer surface of the ice layer on the surface of the power cable is cut with multiple gaps. When the knocking block is knocked later, the ice layer wrapped around the outer surface of the power cable can be knocked off more easily and comprehensively, so that the overall de-icing effect is better. When encountering thick ice, the cutter is squeezed by the thick ice layer and drives the limit rod to move When the cutter is in the ice, the first conducting block is synchronously driven to move and contact the second conducting block, and the heating block in the groove inside the cutter is energized to generate heat, thereby improving the cutting effect of the cutter and speeding up the ice cutting and de-icing. When encountering a thinner ice layer, the cutter is no longer subjected to the resistance pressure. At this time, the limit rod drives the cutter to move back and reset, thereby separating the first conducting block from the second conducting block. At this time, the heating block is powered off and no longer generates heat, reducing electricity usage and saving energy consumption. The device as a whole can automatically control the power on and off of the heating block according to the thickness of the ice layer, making it convenient to use.

[0018] 2. As the rotating shaft drives the friction block to rotate, it also drives the disc on one side to rotate synchronously. In conjunction with the installation of the auxiliary frame, limit column, and guide groove, the rotation of the disc drives the rack to reciprocate. When the ice on the power cable is processed by the slitting and de-icing mechanism and enters the interior of the multiple surrounding pressure rollers, the limit ring on one side drives the multiple rotating pressure rollers inside and the grinding discs installed outside to reciprocate and grind the surface of the power cable to remove ice. This completely removes any ice residue that may remain on the surface of the power cable, resulting in a better overall de-icing effect.

[0019] 3. When the ice on the power cable is processed by the surrounding grinding mechanism, the rotation of the disc drives the rack to reciprocate, which will drive the piston rod installed on the top side to perform synchronous reciprocating motion inside the suction cylinder. At the same time, the one-way liquid inlet valve pipe, the one-way liquid discharge valve pipe and the arc-shaped guide tube are connected, and the nozzle is driven to rotate back and forth through the limit ring, so that the deicing agent retained in the liquid storage tank can be effectively sprayed on the surface of the power cable in a surrounding manner, so that the overall anti-icing effect is better, the time of secondary icing is extended, and the stable use of the power cable is ensured.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figures 1-11 The present invention provides a technical solution: an anti-icing device for power cables, comprising a mounting frame 1, a driving wheel 2 and an auxiliary wheel 3 are longitudinally and symmetrically mounted on one side of the mounting frame 1, a limiting groove 4 is embedded inside one side of the mounting frame 1, one end of the auxiliary wheel 3 is slidably mounted inside the limiting groove 4 through a slider, and a spring compression rod 5 is installed between the slider at one end of the auxiliary wheel 3 and the top inner wall of the limiting groove 4, a driving motor 6 is installed on one side of the mounting frame 1, and a rotating shaft 7 is installed internally and rotated through one side of the mounting frame 1 near the middle position, a chain sprocket transmission assembly 8 is installed between the output shaft of the driving motor 6 and one end of the rotating shaft 7 for transmission connection, a gear transmission assembly 9 is installed between one end of the driving wheel 2 and one end of the rotating shaft 7 for meshing transmission, a slit deicing mechanism 10 is provided on the outside of one side edge of the mounting frame 1, and a surrounding grinding mechanism 11 is provided between the driving wheel 2 and the slit deicing mechanism 10.

[0034] When the power cable anti-icing device provided by this solution is actually used, the device is first hung and installed on the outside of the power cable that needs to be cleared of ice, and then the drive motor 6 on one side is started by remote control. The output shaft of the drive motor 6 rotates and the transmission setting of the chain sprocket transmission component 8 and the gear transmission component 9 is coordinated, thereby driving the drive wheel 2 on one side to start rotating and cooperate with the auxiliary wheel 3 and the spring compression rod 5 to rebound and squeeze assisted, so that the device as a whole can move on the power cable, and the cutting and deicing mechanism 10 is triggered to operate during the movement, so as to clear the ice. The ice layer on the surface of the power cable is cut with multi-directional surrounding pressure, so that multiple gaps are cut on the outside of the ice layer on the surface of the power cable. When knocking in the later stage, the ice layer wrapped around the outside of the power cable can be knocked off more easily and comprehensively, so that the overall de-icing effect is better. When the ice on the power cable is processed by the cutting and de-icing mechanism 10 and enters the inside of the surrounding grinding mechanism 11, the surrounding grinding mechanism 11 is synchronously triggered to operate, so that reciprocating rotation grinding and de-icing can be performed on the surface of the power cable, and ice debris that may remain on the surface of the power cable is completely cleared in a surrounding manner, so that the overall de-icing effect is better.

[0035] In some embodiments, the slitting and de-icing mechanism 10 includes an open ring 1001, a limit plate 1002, a limit rod 1003, a cutter 1004 and a resistance spring 1005. One side of the open ring 1001 is fixed to the outside of one side of the mounting frame 1 through a bracket. Several limit plates 1002 are fixed laterally at equal angles around the outside of one side of the open ring 1001. The limit rods 1003 are symmetrically and slidingly installed inside the two sides of the limit plate 1002. The cutter 1004 is connected and fixed to the outside of one side of the two symmetrically arranged limit rods 1003. The resistance spring 1005 is sleeved through the outside of one side of the limit rod 1003. The two ends of the resistance spring 1005 are respectively installed on one side of the limit plate 1002 and the cutter 1004.

[0036] Combine Figure 1 、 Figure 3 and Figure 4 As shown, when the device encounters a thin layer of ice during movement, the ice layer will interfere with the cutter 1004 on one side, causing the cutter 1004 to drive the compression of the interference spring 1005 and the movement of the limit rod 1003 for a short distance. The slight interference of the interference spring 1005 enables the cutter 1004 to squeeze the ice layer. At the same time, with the multiple settings of the cutter 1004, the cutter 1004 can apply multi-directional pressure to the ice layer, so that the device will drive the cutter 1004 to cut the surface of the ice layer during operation, so that multiple gaps are cut on the outside of the ice layer on the surface of the power cable. Later, when knocking, the ice layer wrapped around the outside of the power cable can be knocked off more easily and comprehensively, so that the overall de-icing effect is better.

[0037] In some embodiments, the slitting and de-icing mechanism 10 further includes a placement slot 1006, a heating block 1007, a wire 1008, a conducting block 1009, an auxiliary rod 1010, a conducting block 2 1011 and a limit spring 1012. The cutter 1004 is provided with a placement slot 1006 inside the cutter 1004 near the blade, and a heating block 1007 is fixed inside the placement slot 1006. A wire 1008 is fixed on one side of the top of the limiting plate 1002. A conducting block 1009 is fixed on the outside of the limiting rod 1003 away from the cutter 1004. Block 1009, an auxiliary rod 1010 is symmetrically fixed on the outside of the limiting plate 1002 near the conductive block 1009, and the auxiliary rod 1010 and the limiting rod 1003 are arranged in parallel, and a conductive block 2 1011 is slidably installed on the outside of one side of the auxiliary rod 1010, and the conductive block 2 1011 is conductively connected to one end of the wire 1008, and a limiting spring 1012 is sleeved on the outside of one side of the auxiliary rod 1010, and both ends of the limiting spring 1012 are respectively installed on one side of the limiting plate 1002 and the auxiliary rod 1010.

[0038] Combine Figure 1 、 Figure 3 、 Figure 4 and Figure 5 As shown, when the device encounters a thick ice layer during movement, the cutter 1004 is squeezed by the thick ice layer and drives the limit rod 1003 to move a large distance. With the connection between the external power supply and the wire 1008 and the connection between the wire 1008 and the conductive block 2 1011, the limit rod 1003 drives the conductive block 1 1009 to move and contact the conductive block 2 1011 after moving a certain distance, thereby energizing the heating block 1007 in the internal placement groove 1006 of the cutter 1004 to quickly generate heat, thereby making the cutter The cutting effect of 1004 is better, which can speed up the cutting and de-icing. At the same time, when encountering a thinner ice layer, the cutter 1004 is no longer subjected to resistance pressure. At this time, the resistance spring 1005 will drive the limit rod 1003 and the cutter 1004 to move back and reset a certain distance, so that the conductive block 1009 is separated from the conductive block 2 1011. At this time, the heating block 1007 is powered off and no longer generates heat, reducing electricity use and saving energy consumption. The device as a whole can automatically control the power on and off of the heating block 1007 according to the thickness of the ice layer, which is convenient to use.

[0039] At the same time, the auxiliary rod 1010 and the limit spring 1012 limit the conducting block 2 1011, so that after the conducting block 1 1009 contacts the conducting block 2 1011, the limit rod 1003 can still drive the conducting block 1009 to move outward, and at the same time, it can also ensure that the conducting block 1 1009 is still in contact with the conducting block 2 1011 at this time, ensuring that the device can still operate stably when encountering ice layers of different thicknesses to avoid movement conflict.

[0040] In some embodiments, the slitting and de-icing mechanism 10 also includes an X-shaped frame 1013, a resistance block 1014, a knocking block 1015 and a tension spring 1016. The X-shaped frame 1013 is rotatably mounted on the outside of one side of the mounting frame 1. A resistance block 1014 is provided inside the angle of one side of the X-shaped frame 1013, and one end of the resistance block 1014 is fixed to one end of the rotating shaft 7. A knocking block 1015 is fixed on the outside of one side of the X-shaped frame 1013 close to the cutter 1004, and a tension spring 1016 is connected and fixed between the two side ends of the X-shaped frame 1013 close to the resistance block 1014.

[0041] When the ice layer on the outside of the power cable is cut by the cutter 1004 and enters between the knocking blocks 1015, the rotation of the rotating shaft 7 drives the resistance block 1014 to rotate, and the rebound of the tension spring 1016 causes the X-shaped frame 1013 to open and close, thereby driving the knocking block 1015 to move back and forth to knock the ice layer after the cut, so that the ice falls off, and the overall anti-icing cleaning effect is better.

[0042] In some embodiments, the surrounding grinding mechanism 11 includes a limiting ring 1101, a fixing frame 1102, a slide 1103, a limiting roller 1104, a cutout 1105 and a fixing plate 1106. The limiting ring 1101 is symmetrically arranged on the outside of one side of the X-shaped frame 1013, and the outside of the limiting ring 1101 away from the X-shaped frame 1013 is penetrated with a cutout 1105. The fixing frame 1102 is fixed to the outside of the side of the mounting frame 1 close to the limiting ring 1101. A plurality of limiting rollers 1104 are rotatably installed on one side of the fixing frame 1102. The limiting ring 1101 is embedded with a slide on the side close to the fixing frame 1102. 1103, one end of the limiting roller 1104 is slidably engaged and installed inside one side of the slide groove 1103, and a number of fixed plates 1106 are fixed around the two limiting rings 1101 at equal angles; the surrounding grinding mechanism 11 also includes a resistance rod 1107, a mounting seat 1108, a pressure roller 1109 and a grinding sheet 1111, and the two sides of the fixed plate 1106 are symmetrically slidably installed with a resistance rod 1107 inside, and the resistance rod 1107 is fixed at one end near the middle position of the limiting ring 1101.

An auxiliary frame 1113 is installed longitudinally through the bracket, and the auxiliary frame 1113 is set in an inverted T shape. A guide groove 1115 is horizontally penetrated inside the bottom end of the auxiliary frame 1113, and a limiting column 1114 is installed at the outer edge of the disk 1112 near the auxiliary frame 1113, and the limiting column 1114 is slidably connected with the guide groove 1115.

[0043] Combine Figure 1 、 Figure 6 and Figure 7As shown, when the ice on the power cable is processed by the cutting and de-icing mechanism 10 and enters the interior of multiple surrounding pressure rollers 1109, at this time, because the rotating shaft 7 drives the resistance block 1014 to rotate, it will drive the disc 1112 on one side to rotate synchronously, and the rotation of the disc 1112 drives the limiting column 1114 to rotate synchronously. Through the sliding installation of the limiting column 1114 and the guide groove 1115, the rotation of the disc 1112 can drive the auxiliary frame 1113 to perform longitudinal reciprocating motion, thereby driving the rack 1117 to operate synchronously, so that the rack 1117 drives the meshing open gear ring 1116 on one side and the limiting ring 1101 inside it to rotate synchronously, thereby driving the multiple rotatably installed pressure rollers 1109 inside the limiting ring 1101 and the grinding sheet 1111 installed outside it to reciprocate on the surface of the power cable to grind and de-ice. Figure 9 As shown, ice debris that may remain on the surface of the power cable is completely removed by grinding around it, so that the overall deicing effect is better.

[0044] At the same time, the cutout 1105 is provided on one side of the limiting ring 1101 to facilitate placement of the power cable into the inside of the limiting ring 1101 from the side.

[0045] By installing and cooperating the fixing frame 1102, the sliding groove 1103 and the limiting roller 1104, the stability of the limiting ring 1101 during rotation can be ensured, and the smooth operation of the entire device can be ensured.

[0046] At the same time, the resistance rod 1107, the mounting seat 1108 and the compression spring 1110 are installed in coordination and resistance, so that the pressure roller 1109 can be attached to the ice debris on the surface of the power cable during rotation, so that the overall rotation grinding and de-icing effect is better and the cleaning is more complete.
