Description

Technical Field

[0001] The invention belongs to the technical field of high-voltage electric equipment cleaning, and in particular relates to a live cleaning robot for high-voltage electric equipment. Background Art

[0002] Insulators are an important component in high-voltage power equipment. Their main functions are to achieve electrical insulation and mechanical fixation. Since insulators are exposed to the outdoor environment for a long time, a large amount of dirt, such as dust and bird droppings, is easily attached to their surface. When dirt is exposed to moisture for a long time, a conductive film will form on the surface of the insulator, which will greatly reduce the insulation capacity of the insulator, and then cause pollution flashover, which will seriously affect the safe operation of the power system and the normal power consumption of nearby residents.

[0003] In the existing cleaning of insulators on high-voltage power equipment, most of them are cleaned manually using a spray gun with a special live cleaning agent. Although the cleaning equipment has certain safety performance, some unexpected situations are inevitable. At the same time, due to the factors of the installation environment and installation location of some insulators, it is inconvenient to clean them manually. What is more troublesome is that dust and bird droppings that have been attached to the insulators for a long time are difficult to be effectively removed during manual cleaning. Therefore, a live cleaning robot for high-voltage power equipment is proposed. Summary of the invention

[0009] Furthermore, the crossbeam includes a first cross bar and a second cross bar, the first cross bar is fixedly connected to the vertical beam, a connecting block is fixedly connected to the first cross bar, both ends of the second cross bar are fixedly connected to connecting pieces, the connecting block and the connecting piece are rotatably connected via a pin shaft, and the connecting block and the connecting piece are connected via bolts; it also includes a limiting buckle fixedly connected to the first cross bar, the limiting buckle is close to the screw rod, and the synchronous belt passes through the limiting buckle.

[0010] Furthermore, a cleaning flexible sleeve is arranged on the outer periphery of the cylindrical airbag, and a groove is opened on the cleaning flexible sleeve. One end of the cleaning brush strip passes through the groove to the outside of the cleaning flexible sleeve. The groove is long and the length direction of the groove is arranged along the circumferential direction of the cylindrical airbag.

[0011] Preferably, an air cavity is provided in the cleaning brush strip, and the end of the cleaning brush strip is open and communicated with the cylindrical airbag, the injection tube is fixedly connected in the air cavity, the rotating shaft is hollow, and the end of the air cavity is connected to the rotating shaft through a connecting tube.

[0012] Furthermore, the first arm and the second arm are both fixedly connected with a mounting plate, the mounting plate is fixedly connected with a mounting box, a hollow tube is rotatably connected in the mounting box, the hollow tube is fixedly connected to the rotating shaft, and the hollow tube is communicated with the rotating shaft, a blade assembly is fixedly connected to the outer periphery of the hollow tube located in the mounting box, a high-pressure liquid inlet pipe and a liquid outlet pipe are respectively fixedly connected to the mounting box, one end of the liquid outlet pipe is rotatably connected to the hollow tube, so as to pump cleaning agent into the mounting box through the high-pressure liquid inlet pipe to drive the rotating shaft to rotate.

[0013] Furthermore, an air inlet pipe is rotatably connected to the end of the rotating shaft away from the installation box, and the cavity at the end of the rotating shaft away from the installation box is connected to the cylindrical airbag; it also includes an air release pipe connected to the air inlet pipe through an electromagnetic valve, and an air jet hole is opened on the air release pipe.

[0014] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art: when cleaning the insulator on the high-voltage power equipment, the present invention changes the gas pressure in the cylindrical airbag, thereby changing the hard and soft state of the cylindrical airbag, so that when the cleaning brush bar is in a hard state, the dust and bird droppings adhering to the surface of the insulator can be efficiently brushed, thereby removing the stubborn dust and bird droppings adhering to the surface of the insulator, and when the cylindrical airbag is deflated, the cylindrical airbag becomes soft from hard, and the cylindrical airbag is pushed close to the insulator by the cylinder, so that the cylindrical airbag A part of the bag is covered on the insulator, and when the rotating shaft drives the cylindrical air bag to rotate, the cleaning brush strip will bend and closely contact the surface of the cylindrical air bag, so that the cylindrical air bag has a wiping and cleaning effect on the surface of the insulator, and the bent cleaning brush strip will continue to spray the cleaning agent on the surface of the insulator, cooperate with the cylindrical air bag to clean the insulator, thereby improving the cleaning effect of residual dust and bird droppings, further compensating for the defect of insufficient cleaning force for dust and bird droppings due to the gaps between the cleaning brush strips, thereby further improving the cleaning effect on the surface of the insulator;

[0015] Secondly, by arranging a cleaning flexible sleeve on the outer periphery of the cylindrical airbag, when the cylindrical airbag is in a soft state and close to the surface of the insulator, when the cylindrical airbag rotates, the cleaning brush strip will be folded into the groove of the cleaning flexible sleeve when it is bent to fill the groove. At this time, the surface of the cleaning flexible sleeve can contact the surface of the insulator with a maximum area, thereby increasing the contact area with the surface of the insulator. Compared with the cylindrical airbag cleaning the surface of the insulator, the influence of the thickness of the bent cleaning brush strip, which causes the cylindrical airbag to be loosely attached to the surface of the insulator, can be avoided. Furthermore, by arranging the cleaning flexible sleeve and storing the cleaning brush strip in the groove, the effect of wiping and cleaning the surface of the insulator can be effectively improved, so that the cleaning effect is better and the cleaning efficiency is higher.

[0016] At the same time, the length and width of the groove are greater than the length and width of the cleaning brush strip after bending, so when the cleaning brush strip is bent into the groove, there is still a certain amount of space in the groove. Therefore, when the cleaning flexible sleeve and the surface of the insulator are wiped and cleaned, the dirt will enter the groove and temporarily remain in the groove, thereby preventing the dirt wiped by the cleaning flexible sleeve from remaining on the surface of the cleaning flexible sleeve, resulting in the situation that the surface of the insulator is not wiped clean.

[0017] During the rotation of the cylindrical airbag, after the cleaning brush bar does not contact the insulator, the cleaning brush bar pops out from the groove, and in the process of popping out, the dirt in the groove is taken out, thereby achieving the effect of automatically discharging the dirt, so that the cleaning flexible sleeve can maintain a good wiping effect for a long time during the process of wiping and cleaning the surface of the insulator;

[0018] Therefore, the live cleaning robot for high-voltage electric equipment can change between soft and hard states through the cylindrical airbags and the cleaning brush strips, thereby achieving the effect of efficiently cleaning stubborn stains such as dust and bird droppings.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0033] Example 1: Reference Figure 1-Figure 11A live cleaning robot for high-voltage electric equipment comprises a gantry support 1 composed of a cross beam 11 and vertical beams 12 symmetrically arranged at both ends of the cross beam 11, and further comprises: a cross connecting frame 13 is arranged on each of the two vertical beams 12, and a first arm 131 and a second arm 132 are symmetrically and rotatably connected to the cross connecting frame 13; a rotating shaft 151 is rotatably connected between the first arm 131 and the second arm 132 symmetrically arranged; a cylindrical airbag 15 is fixedly connected to the rotating shaft 151; a cleaning brush strip 152 is arranged on the outer periphery of the cylindrical airbag 15, and a spray pipe 154 for spraying a cleaning agent is arranged in the cleaning brush strip 152, and an opening of the spray pipe 154 is located at the top of the cleaning brush strip 152; the cylindrical airbag 15 is inflated to make the cylindrical airbag 15 circular and change from soft to hard, and the cleaning brush strip 152 also changes from soft to hard and convex The outer periphery of the cylindrical airbag 15 is used to scrub the surface of the object; when the cylindrical airbag 15 is deflated, the cylindrical airbag 15 and the cleaning brush strip 152 become soft from hard, and the cylindrical airbag 15 is pushed close to the surface of the object by the driving mechanism, so that the cylindrical airbag 15 is concave near the outer periphery of the object and fits on the surface of the object to scrub the surface of the object; the driving mechanism includes a cylinder 133, and the cross connecting frame 13 is symmetrically fixedly connected with mounting arms 134, and the cylinders 133 are respectively installed on the symmetrical mounting arms 134, and the first arm 131 and the second arm 132 are fixedly connected with connecting rods 136, and the telescopic end of the cylinder 133 is in contact with the connecting rod 136, and the first arm 131 and the second arm 132 are connected by an elastic plate 130, and the elastic plate 130 is used to facilitate the reset of the first arm 131 and the second arm 132;

[0034] When the live cleaning robot for high-voltage electric equipment is in use, four cylindrical air bags 15 located on the gantry support 1 are inserted onto the outer periphery of the insulator, so that the insulator is located between the four cylindrical air bags 15, and then the insulator is surrounded by the four cylindrical air bags 15;

[0035] When cleaning the surface of the insulator, the four cylindrical airbags 15 are first filled with gas, so that the cylindrical airbags 15 are in a full state. When the cylindrical airbags 15 are inflated, the cleaning brush strips 152 on the cylindrical airbags 15 are also inflated, so that the cleaning brush strips 152 are straight and then change from a soft state to a hard state. After the cylindrical airbags 15 are inflated, the cylindrical airbags 15 are in a full state, and a certain distance is left between the outer wall and the surface of the insulator. When the four cylindrical airbags 15 are driven to rotate, the hardened cleaning brush strips 152 will have a cleaning effect on the surface of the insulator. When the cylindrical airbags 15 are in a hard state, when the cleaning brush strips 152 are in contact with the surface of the insulator in the hard state, the supporting effect of the cleaning brush strips 152 is enhanced, and thus they will not bend arbitrarily, so that the brushing effect on dust and bird droppings is enhanced.

[0036] Since the cleaning brush strip 152 is provided with a spray pipe 154, the prepared cleaning agent will be pumped into the spray pipe 154 and sprayed out, so that when the cylindrical airbag 15 rotates, the cleaning brush strip 152 cleans the surface of the insulator and sprays the cleaning agent onto the surface of the insulator, thereby increasing the cleaning effect on the surface of the insulator. Since the cleaning brush strip 152 is in a hard state at this time, it can effectively remove dust and bird droppings adhering to the surface of the insulator, thereby increasing the cleaning effect on the surface of the insulator.

[0037] When the cylindrical airbag 15 and the cleaning brush strip 152 are in a hard state and clean the surface of the insulator, the cylindrical airbag 15 is deflated. After deflated, the cylindrical airbag 15 changes from a hard state to a soft state. Since the air pressure in the cylindrical airbag 15 decreases, the gas pressure in the cleaning brush strip 152 also decreases, so the cleaning brush strip 152 also changes from a hard state to a soft state.

[0038] At this time, the cylinder 133 in the driving mechanism pushes the first arm 131 and the second arm 132 to rotate on the cross connecting frame 13, so that the first arm 131 and the second arm 132 are close to each other, thereby pushing the cylindrical airbag 15 to close to the surface of the insulator. At this time, due to the reduction of gas and air pressure in the cylindrical airbag 15, when the cylindrical airbag 15 is close to the insulator, the part of the cylindrical airbag 15 that contacts the insulator will be concave (refer to Fig.11 ), at this time, a large area of ​​the surface of the cylindrical airbag 15 will be in contact with the insulator, and because the cylindrical airbag 15 is deflated, the cleaning brush strip 152 will also become soft. Therefore, when the rotating shaft 151 drives the cylindrical airbag 15 to rotate, the cleaning brush strip 152 will bend and close to the surface of the cylindrical airbag 15, so that the cylindrical airbag 15 has a wiping and cleaning effect on the surface of the insulator, and the bent cleaning brush strip 152 will continue to spray the cleaning agent on the surface of the insulator, cooperate with the cylindrical airbag 15 to clean the insulator, and then clean the residual dust and bird droppings again, making up for the defect of insufficient cleaning of dust and bird droppings due to the gaps between the cleaning brush strips 152;

[0039] Therefore, when the device cleans the insulator on the high-voltage power equipment, the gas pressure in the cylindrical airbag 15 is changed, thereby changing the hard and soft state of the cylindrical airbag 15, so that when the cleaning brush strip 152 is in the hard state, the dust and bird droppings adhering to the surface of the insulator can be efficiently brushed, thereby removing the stubborn dust and bird droppings. When the cylindrical airbag 15 is deflated, the cylindrical airbag 15 becomes soft from hard, and the cylindrical airbag 15 is pushed close to the insulator by the cylinder 133, so that a part of the cylindrical airbag 15 is covered on the insulator, and When the rotating shaft 151 drives the cylindrical airbag 15 to rotate, the cleaning brush strip 152 will bend and closely abut against the surface of the cylindrical airbag 15, so that the cylindrical airbag 15 has a wiping and cleaning effect on the surface of the insulator, and the bent cleaning brush strip 152 will continue to spray the cleaning agent on the surface of the insulator, cooperate with the cylindrical airbag 15 to clean the insulator, thereby improving the cleaning effect of residual dust and bird droppings, further compensating for the defect of insufficient cleaning force for dust and bird droppings due to the gaps between the cleaning brush strips 152, thereby further improving the cleaning effect of the insulator surface;

[0040] It should be understood that when the diameter of the insulator to be cleaned is small, the four cylindrical air bags 15 can completely wrap the insulator when they are close to the insulator;

[0041] When the diameter of the insulator is large, the insulator cannot be completely wrapped due to the influence of the diameter of the cylindrical airbag 15. Therefore, when cleaning the surface of the insulator, the gantry bracket 1 is properly rotated to change the position of the cylindrical airbag 15 on the insulator, so that the surface of the insulator can be completely cleaned;

[0042] In addition, this high-voltage electric equipment live cleaning robot can not only efficiently clean the insulators in the high-voltage electric equipment, but also clean other cylindrical parts of the high-voltage electric equipment or cylindrical parts on other equipment.

[0043] Example 2: Reference Figure 1 , Figure 2 , Figure 3 , a live cleaning robot for high-voltage power equipment, which is basically the same as that of Example 1, further comprising: a mounting frame 17 is mounted on the crossbeam 11, the mounting frame 17 is perpendicular to the crossbeam 11, both ends of the mounting frame 17 are rotatably connected to rubber wheels 171, a second motor 172 is mounted on the mounting frame 17, and an output end of the second motor 172 is connected to the rubber wheel 171;

[0044] The provision of the rubber wheel 171 can facilitate the movement of the gantry support 1 on the insulator, thereby continuously cleaning the surface of the insulator.

[0045] The symmetrical vertical beams 12 on the gantry support 1 are all rotatably connected with screw rods 14, the vertical beams 12 are fixedly connected with guide rails 121, the cross connecting frame 13 is fixedly connected with a slide 135, the slide 135 is slidably connected to the guide rail 121, the slide 135 is threadedly connected to the screw rods 14, the symmetrical screw rods 14 are connected by a synchronous belt 141, and a first motor 143 is installed on the vertical beam 12, and the first motor 143 is connected to one end of one of the screw rods 14;

[0046] The first motor 143 drives one of the screw rods 14 to rotate, and the two screw rods 14 are connected by the synchronous belt 141 to rotate at the same time, thereby driving the cross connecting frames 13 on both sides of the gantry bracket 1 to move up and down synchronously, so as to facilitate the adjustment of the distance between the rubber wheel 171 and the cylindrical airbag 15, so that when the gantry bracket 1 needs to move, the rubber wheel 171 is close to the insulator. At the same time, the up and down adjustment of the cross connecting frame 13 can facilitate the adjustment of the distance between the cylindrical airbag 15 and the crossbeam 11.

[0047] Example 3: Reference Figure 1 , Figure 2 , Figure 3 , a live cleaning robot for high-voltage power equipment is basically the same as that of Example 2, and further, the crossbeam 11 includes a first crossbar 112 and a second crossbar 111, the first crossbar 112 is fixedly connected to the vertical beam 12, a connecting block 113 is fixedly connected to the first crossbar 112, and both ends of the second crossbar 111 are fixedly connected to connecting members 114, the connecting block 113 and the connecting member 114 are rotatably connected through a pin shaft 115, and the connecting block 113 and the connecting member 114 are connected through a bolt 116; and also includes a limit buckle 142 fixedly connected to the first crossbar 112, the limit buckle 142 is close to the screw rod 14, and the synchronous belt 141 passes through the limit buckle 142;

[0048] When not in use, the bolts 116 are removed, and the vertical beams 12 are folded inward through the first cross bar 112, so that the vertical beams 12 on both sides of the first cross bar 112 are folded and stored in the middle of the second cross bar 111, which is convenient for reducing the volume and convenient for carrying;

[0049] When folding, the limiting buckle 142 can prevent the synchronous belt 141 from falling off the synchronous wheel at one end of the screw rod 14, thereby limiting the synchronous belt 141, so that when unfolding and using, the synchronous belt 141 is conveniently connected to the synchronous wheels of the two screw rods 14;

[0050] Furthermore, a handle 144 is installed on the second cross bar 111 to facilitate lifting the gantry bracket 1.

[0051] Example 4: Reference Figure 1 , Figure 6 , Figure 7 , Fig. 9 , a live cleaning robot for high-voltage electric equipment, which is basically the same as that of the third embodiment, and furthermore: a cleaning flexible sleeve 156 is provided on the outer periphery of the cylindrical airbag 15, and a groove 157 is provided on the cleaning flexible sleeve 156, and one end of the cleaning brush strip 152 passes through the groove 157 to the outside of the cleaning flexible sleeve 156, and the groove 157 is in a long strip shape, and the length direction of the groove 157 is arranged along the circumferential direction of the cylindrical airbag 15;

[0052] The cleaning flexible cover 156 is made of sponge or latex material;

[0053] By setting the cleaning flexible sleeve 156 on the outer periphery of the cylindrical airbag 15, when the cylindrical airbag 15 is in a soft state and close to the surface of the insulator, when the cylindrical airbag 15 rotates, the cleaning brush strip 152 will be folded into the groove 157 of the cleaning flexible sleeve 156 when it is bent, and the groove 157 is filled. At this time, the surface of the cleaning flexible sleeve 156 can contact the surface of the insulator with a maximum area, so that the contact area with the surface of the insulator can be increased. Compared with the cylindrical airbag 15 cleaning the surface of the insulator, the influence of the thickness of the bent cleaning brush strip 152 can be avoided, resulting in the cylindrical airbag 15 and the insulator surface not fitting tightly. Further, by setting the cleaning flexible sleeve 156 and accommodating the cleaning brush strip 152 into the groove 157, the effect of wiping and cleaning the surface of the insulator can be effectively improved, so that the cleaning effect is better and the cleaning efficiency is higher.

[0054] At the same time, the length and width of the groove 157 are greater than the length and width of the cleaning brush strip 152 after bending. Therefore, when the cleaning brush strip 152 is bent into the groove 157, there is still a certain amount of space in the groove 157. Therefore, when the cleaning flexible sleeve 156 and the surface of the insulator are wiped and cleaned, the dirt will enter the groove 157 and temporarily remain in the groove 157. Therefore, it can be avoided that the dirt wiped by the cleaning flexible sleeve 156 remains on the surface of the cleaning flexible sleeve 156, resulting in the situation that the surface of the insulator is not wiped clean.

[0055] During the rotation of the cylindrical airbag 15, after the cleaning brush strip 152 is no longer in contact with the insulator, the cleaning brush strip 152 pops out from the groove 157, and in the process of popping out, the dirt in the groove 157 is brought out, thereby achieving the effect of automatically discharging the dirt, so that the cleaning flexible sleeve 156 can maintain a good wiping effect for a long time during the process of wiping the surface of the insulator.

[0056] Example 5: Reference Figure 1 , Figure 2 , Figure 5 , Fig.10, a live cleaning robot for high-voltage power equipment, which is basically the same as that of Example 4, and further, an air cavity 153 is provided in the cleaning brush strip 152, and the end of the cleaning brush strip 152 is open and communicated with the cylindrical air bag 15, a spray pipe 154 is fixedly connected in the air cavity 153, a rotating shaft 151 is hollow, and the end of the air cavity 153 is connected to the rotating shaft 151 through a connecting pipe 155;

[0057] When the cleaning agent enters the rotating shaft 151, the cleaning agent enters the spray pipe 154 through the soft connecting pipe 155 and is sprayed out;

[0058] When the cylindrical airbag 15 is inflated, the gas will enter the air cavity 153, thereby making the cleaning brush strip 152 hard.

[0059] The first arm 131 and the second arm 132 are both fixedly connected with a mounting plate 16, and a mounting box 161 is fixedly connected to the mounting plate 16. A hollow tube 162 is rotatably connected in the mounting box 161, and the hollow tube 162 is fixedly connected to the rotating shaft 151, and the hollow tube 162 is communicated with the rotating shaft 151. A blade assembly 163 is fixedly connected to the outer periphery of the hollow tube 162 located in the mounting box 161, and a high-pressure liquid inlet pipe 164 and a liquid outlet pipe 165 are respectively fixedly connected to the mounting box 161, and one end of the liquid outlet pipe 165 is rotatably connected to the hollow tube 162, so as to pump cleaning agent into the mounting box 161 through the high-pressure liquid inlet pipe 164 to drive the rotating shaft 151 to rotate;

[0060] By connecting the external water pipe to the high-pressure liquid inlet pipe 164, the cleaning agent is pumped into the installation box 161, and the cleaning agent impacts the blade assembly 163 in the installation box 161, so that the hollow tube 162 rotates, and then drives the rotating shaft 151 to rotate. Therefore, the rotating shaft 151 can be driven to rotate without using external electrical equipment, making the device lightweight;

[0061] The cleaning agent entering the installation box 161 will enter the hollow tube 162 through the liquid outlet pipe 165. Since the hollow tube 162 is connected to the rotating shaft 151, the pumped cleaning agent will enter the rotating shaft 151 and then be sprayed out from the spray pipe 154.

[0062] An air inlet pipe 181 is rotatably connected to one end of the rotating shaft 151 away from the installation box 161, and a cavity 1511 at one end of the rotating shaft 151 away from the installation box 161 is connected to the cylindrical airbag 15; and an air discharge pipe 182 is also included, which is connected to the air inlet pipe 181 through a solenoid valve, and an air jet hole is opened on the air discharge pipe 182;

[0063] The gas is connected to the air inlet pipe 181 through the external inflation pipe, and the gas enters the cavity 1511 in one end of the rotating shaft 151 through the air inlet pipe 181. A connecting hole is opened on the outer periphery of the rotating shaft 151 at the cavity 1511, and the gas is filled into the cylindrical airbag 15 through the connecting hole.

[0064] When deflation is required, the gas in the cylindrical airbag 15 enters the deflation pipe 182 through the solenoid valve and is sprayed onto the cylindrical airbag 15 from the jet hole. On the one hand, it can facilitate the discharge of the gas in the cylindrical airbag 15, and on the other hand, the gas can be sprayed onto the cleaning flexible sleeve 156 on the cylindrical airbag 15 to further clean the cleaning flexible sleeve 156, thereby improving the wiping and cleaning effect on the surface of the insulator.

[0065] The present invention changes the hard and soft state of the cylindrical airbag 15 by changing the gas pressure in the cylindrical airbag 15 when cleaning the insulator on the high-voltage power equipment, so that when the cleaning brush strip 152 is in the hard state, the dust and bird droppings adhering to the surface of the insulator can be efficiently brushed, and the stubborn dust and bird droppings adhering can be removed. When the cylindrical airbag 15 is deflated, the cylindrical airbag 15 becomes soft from hard, and the cylindrical airbag 15 is pushed close to the insulator by the cylinder 133, so that a part of the cylindrical airbag 15 is covered on the insulator, and When the rotating shaft 151 drives the cylindrical airbag 15 to rotate, the cleaning brush strip 152 will bend and press against the surface of the cylindrical airbag 15, so that the cylindrical airbag 15 has a wiping and cleaning effect on the surface of the insulator, and the bent cleaning brush strip 152 will continue to spray cleaning agent onto the surface of the insulator, cooperate with the cylindrical airbag 15 to clean the insulator, thereby improving the cleaning effect of residual dust and bird droppings, and further compensating for the defect of insufficient cleaning force for dust and bird droppings due to the gaps between the cleaning brush strips 152, thereby further improving the cleaning effect on the surface of the insulator.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with the present invention can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
