Description

Technical Field

[0001] The present invention relates to the technical field of high-voltage cable boxes, and more specifically, to a high-voltage cable branch box. Background Art

[0002] A cable branch box is a transmission tool used to supply power to high-voltage cables for transmission. It helps technicians to plug and unplug cables at designated cable connectors in a safe power-off environment, and then assists the cables in transmitting various high-voltage and low-voltage currents in the energized state to various power consumption occasions for people's daily electricity use.

[0003] Most of the existing cable branch boxes are installed on the ground surface, which not only takes up a lot of ground space, but also the high-voltage cable branch boxes are usually installed on the edge of the road, which is vulnerable to damage from external factors, causing unnecessary safety hazards such as electric shock when vehicles and pedestrians pass through the road.

[0004] In response to the above technical problems, the prior art has proposed some solutions. For example, a Chinese patent with authorization announcement number CN101217230B discloses a fully buried high-voltage cable branch box. The high-voltage cable branch assembly, outer box body and inner box body provided in the device can be connected to the input and output ends of the high-voltage cable branch assembly through the outlets of the outer box body and the inner box body, thereby realizing the transmission of various high-voltage and low-voltage currents and completing the power connection and transmission operation of the cable.

[0005] However, in the actual use of the buried cable branch box, since the cable branch box is buried underground for a long time, the side wall of the cable branch box in contact with the inner wall of the pit will be adhered to by some moist soil in the pit, resulting in soil accumulation on the surface of the branch box. In addition, the buried cable branch box is disturbed by the adhesion of these dust and mud for a long time during use, which will cause dust and mud to invade the branch box and contact with electronic components, resulting in safety problems such as arc burning and explosion. Moreover, since the existing fully buried cable branch box is maintained on the ground, this will not only increase the difficulty of operation and low the maintenance efficiency, but if the cable box is taken out of the soil, the safety performance of the cable box will be low after it is pulled to the surface, which seriously affects the maintenance and use of the cable branch box.

[0046] The bottom of the L-shaped rack 26 is penetrated and slidably connected with a semi-open L-shaped plate 27, the front end of the semi-open L-shaped plate 27 is penetrated and inserted into the inner wall of the pit, the outer surface of the double drive gear 25 is penetrated and rotatably connected with the semi-open L-shaped plate 27, and the top front side of the semi-open L-shaped plate 27 is rotatably connected with the semi-arc gear plate 24.

[0047] The outer surface of the dual drive gear 25 is sleeved with a chain 211, and the bottom of the chain 211 is sleeved with a sprocket 212. The two sides of the sprocket 212 are penetrated and fixedly connected with a rotating shaft 213.

There are four column rods 218. The tops of the four column rods 218 are fixedly connected to a push plate 219. The top of the push plate 219 contacts the bottom of the cable box 1.

[0048] The top of the annular cutter head 29 is fixedly connected to a compression spring 210 , and the top of the compression spring 210 is fixedly connected to the inner top wall of the annular telescopic box 28 .

[0049] In view of the fact that the fully buried high-voltage cable branch box in the prior art is in use, since the cable branch box is buried underground for a long time, the side wall of the cable branch box in contact with the inner wall of the pit will be adhered to by part of the moist soil in the pit, resulting in soil accumulation on the surface of the branch box. In addition, the buried cable branch box is disturbed by the adhesion of these dust and mud for a long time during use, which will cause dust and mud to invade the branch box and contact with electronic components, causing safety problems such as arc burning and explosion. Moreover, since the existing fully buried cable box 1 is maintained on the ground, this will not only increase the difficulty of operation and reduce the maintenance efficiency, but also cause the cable box 1 to be taken out of the soil. The safety performance of maintenance will be low after it is pulled to the surface, which seriously affects the maintenance and use of the cable box 1. The present application provides a lifting and scraping assembly 2. When in use, the output shaft of the driving motor 21 in the lifting and scraping assembly 2 is first driven to rotate, and the fixed The swing rod 1 22 connected to the fixed part rotates, and the swing rod 1 22 drives the swing rod 23 to rotate, and the swing rod 23 drives the tooth groove at the right end of the semi-arc tooth plate 24 to rotate, which drives the front gear of the double drive gear 25 to rotate, thereby driving the double drive gear 25 to rotate, and then the double drive gear 25 drives the L-shaped rack 26 engaged at the rear end to move downward, so that the L-shaped rack 26 drives the annular telescopic box 28, the annular cutter head 29 and the extrusion spring 1 210 to move downward, so that the annular cutter head 29 can perform a mobile scraping and cleaning operation on the side of the cable box 1, avoid the accumulated soil and dust from eroding the box body of the cable box 1, reduce the interference of soil and dust on various components in the box body of the cable box 1, strengthen the cleaning force of dust accumulated on the surface of the box body of the cable box 1, maintain the service life of the box body of the cable box 1, and ensure the normal progress of the scraping and cleaning process of the cable box 1;

[0050] At the same time, during the rotation of the dual driving gear 25, the sprocket 212 set at the bottom of the chain 211 can be synchronously driven to rotate, and the sprocket 212 can drive the rotating shaft 213 to rotate, and the rotating shaft 213 can drive the two rotating rods 1 214 to rotate, and then the two rotating rods 1 214 can drive the rotating rod 215 to rotate, so that the rotating rod 215 can push the sliding plate 216 connected to the rotation to move upward, and then the sliding plate 216 can drive the four column rods 218 to move upward, and further the four column rods 218 can push the pushing plate 219 to move upward, so that the pushing plate 219 can push the sliding plate 216 to move upward. The cable box 1 is moved upward, which can assist the annular cutter head 29 in scraping away soil and debris during the upward movement of the cable box 1, thereby avoiding the problem of having to lie on the ground to repair the cable box 1. The force applied during the upward movement of the cable box 1 can enhance the force of the annular cutter head 29 to scrape away soil and debris, and strengthen the scraping effect of the annular cutter head 29 on adhered and compacted soil. The cable box 1 can also be moved up to be flush with the top of the pit, making it convenient for maintenance personnel to stand for maintenance, increasing the convenience of operation, improving the efficiency and safety of maintenance personnel in repairing the cable box 1, and ensuring the normal progress of the maintenance process of the cable box 1.

[0051] It should be noted that the downward scraping process of the annular cutter head 29 and the upward moving process of the cable box 1 are carried out synchronously, so that the cleaning of dust and trace dirt in the cable box 1 can be enhanced, thereby ensuring the normal use and maintenance of the cable box 1.

[0052] This solution provides an L-shaped rack 26, an annular telescopic box 28 and an annular cutter head 29. During the up and down movement of the L-shaped rack 26, the annular telescopic box 28 can be indirectly driven to drive the annular cutter head 29 to move up and down, so that the annular cutter head 29 can perform a mobile scraping operation on the soil debris accumulated on the surface of the cable box 1, thereby preventing the soil pit from coming into contact with the cable box 1, causing part of the moist soil in the soil pit to fall off and adhere to the side wall of the cable box 1, causing the cable box 1 to rust. At the same time, the interference of soil and dust on the components in the cable box 1 is reduced, the cleaning intensity of the surface of the cable box 1 is improved, the use effect of the cable box 1 is enhanced, and the normal scraping process of the cable box 1 is ensured.

[0053] like Figure 5 and Figure 6 As shown, a scraper assembly 3 is provided inside the lifting and scraping assembly 2;

[0054] The scraper assembly 3 includes an annular blade 1 31, the top of which is fixedly connected to the inner top wall of the annular telescopic box 28, the bottom blade edge of which is in contact with the inner annular surface of the annular cutter head 29, the outer annular surface of the annular cutter head 29 is in contact with an annular blade 2 32, and the top of which is fixedly connected to the inner top wall of the annular telescopic box 28.

[0055] By setting up the scraper assembly 3, when in use, the annular telescopic box 28 can be moved downward, so that the annular telescopic box 28 can synchronously drive the annular blade 1 31 and the annular blade 2 32 to move downward, and the annular cutter head 29 can be moved down to the position containing debris and soil close to the side of the cable box 1, so that the cutting edge of the annular cutter head 29 contacts the cutting soil part. At this time, under the influence of the adhesion resistance of the soil debris, the annular cutter head 29 continues to move downward, which will cause the annular cutter head 29 to squeeze the squeezing spring 1 210 to shrink toward the inside of the annular telescopic box 28. At this time, the cutting edges of the annular blade 1 31 and the annular blade 2 32 can be used to shovel dust and soil along the two side walls of the annular cutter head 29, thereby avoiding the interference of residual soil and dust on the secondary scraping process of the annular cutter head 29, improving the accuracy of the annular cutter head 29 in scraping soil and dust, enhancing the service life of the annular cutter head 29, and ensuring the normal progress of the scraping process of the annular cutter head 29.

[0056] In this solution, by setting up a scraper assembly 3, under the action of the continuous telescopic movement of the annular cutter head 29, the annular blade 1 31 and the annular blade 2 32 can scrape away the residual dirt and dust attached to the surface of the annular cutter head 29 after scraping, thereby preventing the residual dust and dirt from rusting the blade of the annular cutter head 29 after the annular cutter head 29 scrapes away the dirt, improving the efficiency of the scraping process of the annular cutter head 29, enhancing the scraping and cleaning force of the annular cutter head 29, and ensuring the normal use of the annular cutter head 29.

[0057] like Figure 7 and Figure 8 As shown, a wiping assembly 4 is provided inside the lifting and scraping assembly 2;

[0058] The wiping assembly 4 includes an electrostatic brush plate 41 , which is fixedly connected to the inner ring surface of the annular telescopic box 28 . There are four electrostatic brush plates 41 , and the four electrostatic brush plates 41 are symmetrically distributed in pairs.

[0059] By setting up the wiping component 4, when working, when the annular telescopic box 28 moves downward, the four electrostatic brush plates 41 can be driven to move downward, so that the brush fiber parts of the four electrostatic brush plates 41 can wipe and clean the dust along the side of the cable box 1, avoiding the residual dust loosened by the annular blade head 29 from being adsorbed on the side of the cable box 1, reducing the adsorption of residual dust, improving the cleaning effect on the surface of the cable box 1, increasing the use effect of the cable box 1 body, and ensuring the normal progress of the cleaning process of the cable box 1.

[0060] It should be noted that the wiping process of the electrostatic brush plate 41 starts to wipe the surface of the cable box 1 only after the annular cutter head 29 completes the scraping process, thereby assisting the annular cutter head 29 to complete the cleaning of dirt and dust.

[0061] like Figures 9 to 12 As shown, a knocking and vibrating component 5 is provided on the top of the lifting and scraping component 2;

[0062] The percussion vibration assembly 5 includes a transmission wheel 2 51, which is fixedly connected to the front side of the semi-arc toothed plate 24. The outer surface of the transmission wheel 2 51 is sleeved with a transmission belt 2 52, and the top of the transmission belt 2 52 is sleeved with a conical wheel 1 53. The front end of the conical wheel 1 53 is fixedly connected with a cylinder 511, and the front end of the cylinder 511 is penetrated and inserted with a cylinder 59, and the outer surface of the cylinder 59 is penetrated and inserted into the inner wall of the pit, and the front end top of the conical wheel 1 53 is meshedly connected with the conical wheel 2 54, and the top of the conical wheel 2 54 is rotatably connected with a support plate 510, and the front end of the support plate 510 is penetrated and inserted into the inner wall of the pit.

[0063] A crank wheel 55 is fixedly connected to the top of the second conical wheel 54 , and a semi-annular sliding rod 56 is sleeved on the outer surface of the crank wheel 55 .

[0064] A T-shaped knocking rod 57 is telescopically inserted into the rear end of the semi-circular sliding rod 56 , and an elastic force spring 58 is fixedly connected between the outer surface of the T-shaped knocking rod 57 and the rear side of the semi-circular sliding rod 56 .

[0065] By setting the knocking vibration component 5, when working, the semi-arc tooth plate 24 rotates, which can drive the second transmission wheel 51 to rotate, and the transmission wheel 51 drives the conical wheel 1 53 set on the top of the second transmission belt 52 to rotate, and the rotation of the conical wheel 1 53 drives the meshing conical wheel 2 54 to rotate, so that the conical wheel 2 54 drives the crank wheel 55 to rotate, and then the crank wheel 55 drives the semi-circular sliding rod 56 to move forward and backward, further making the semi-circular sliding rod 56 The T-shaped knocking rod 57 and the elastic force spring 58 are driven to move forward and backward, so that the T-shaped knocking rod 57 knocks and shakes off the trace dust attached to the surface of the annular telescopic box 28 and the annular cutter head 29, avoiding the dust splashing attached to the surface of the annular telescopic box 28 and the annular cutter head 29, causing secondary plastering on the side of the cable box 1 after scraping, reducing the adhesion of residual splashing dust, and enhancing the cleanliness of the side of the cable box 1 scraped by the annular cutter head 29, ensuring the normal use and maintenance of the cable box 1 without dust.

[0066] It should be noted that the knocking action of the T-shaped knocking rod 57 is that after the semi-annular sliding rod 56 pushes the T-shaped knocking rod 57 to move backward until it contacts the surface of the annular cutter head 29, under the action of the continuous backward impact force of the semi-annular sliding rod 56, the semi-annular sliding rod 56 squeezes the elastic force spring 58 to move toward the rear end of the T-shaped knocking rod 57, so that when the semi-annular sliding rod 56 approaches the rear end position of the T-shaped knocking rod 57, it completes providing vibration force for the knocking vibration of the T-shaped knocking rod 57.

[0067] This solution provides a knocking and vibration component 5, and under the action of the T-shaped knocking rod 57 continuously moving back and forth, the T-shaped knocking rod 57 can knock and vibrate the surface of the annular telescopic box 28 and the annular cutter head 29, so as to avoid interference from the trace dust remaining after scraping by the annular cutter head 29, which may cause secondary dust adhesion on the surface of the cable box 1, reduce the possibility of dust adhesion, maintain the aesthetics of the branch box after cleaning, and ensure the normal use and maintenance of the cable box 1 without dust.

[0068] Method of use: When the present invention is used, firstly, the output shaft of the driving motor 21 in the lifting and scraping assembly 2 is started to rotate, so that the lifting and scraping assembly 2 drives the annular cutter head 29 to move downward, so that the annular cutter head 29 can perform a mobile scraping operation on the side of the cable box 1, and simultaneously the lifting and scraping assembly 2 indirectly drives the push plate 219 to push the cable box 1 upward, so that the lifting and scraping assembly 2 can indirectly drive the scraper assembly 3 to scrape the annular cutter head 29 to remove the dirt and dust, and further the lifting and scraping assembly 2 can indirectly drive the wiping assembly 4 to The surface of the cable box 1 is wiped and cleaned of dust after being scraped by the annular cutter head 29, and at the same time, the lifting and scraping component 2 indirectly drives the knocking and vibrating component 5 to vibrate and clean the residual dust attached to the surface of the annular cutter head 29, and when the push plate 219 moves up to be flush with the top surface of the pit, the maintenance personnel can carry out safe maintenance work on the cable box 1. After the cable box 1 completes the maintenance process, the lifting and scraping component 2 can be started again to drive the output shaft of the motor 21 to rotate again, and indirectly drive the push plate 219 to retract the cable box 1 into the pit again, then the device stops running and the maintenance is completed.

[0069] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto.
