Description

Technical Field

[0001] This invention belongs to the field of power cable technology, specifically relating to a rodent- and ant-proof power cable. Background Technology

[0002] Rodent-proof power cables are special cables designed to prevent damage from rodents, primarily targeting rats and termites. They enhance the sheath's resistance to biting through physical or chemical means, making them widely used in places susceptible to biological erosion, such as power and communication industries. They are especially suitable for underground installations, industrial environments, or warehouses where rodents and termites are prone to infestation.

[0003] The existing Chinese utility model patent with announcement number CN213183676U discloses a rodent-proof power cable. By using a nylon layer, nylon sheath, copper strip, steel strip, and rodent-proof sheath, it can truly achieve the function of rodent-proofing throughout the cable's lifespan. The nylon layer and nylon sheath, made of nylon material, have high hardness and can effectively prevent termite gnawing, while also having good shielding function.

[0004] To prevent rodents and ants from damaging electrical cables, a combination of physical and chemical methods is usually used. The attraction of cables to rodents and ants varies depending on their location. To prevent rodents and ants from gnawing on them, cables are usually laid underground. However, to be successfully connected indoors, electricity needs to pass through walls. Cables may be relatively fixed or slightly bent at the wall penetration points, making them more susceptible to being gnawed on by rodents for extended periods. Therefore, rodent and ant protection is essential in these locations. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a rodent-proof power cable.

[0006] The technical solution adopted to solve the above technical problems is:

[0007] A rodent- and ant-proof power cable, comprising:

[0008] The cable body includes an insulation layer and a plurality of individual wires, the plurality of individual wires being twisted together, the insulation layer being sleeved and installed outside the plurality of individual wires, and a wall-mounting plate being provided on the side wall of the insulation layer;

[0009] A packaging mechanism includes a back panel and a buckle panel. The buckle panel has an arched cross-section and is fastened to the back panel. A sponge board is provided inside the buckle panel. The cable body is located between the buckle panel and the back panel. The sponge board is attached to the cable body. The side wall of the wall-mounted panel is fixedly connected to the side wall of the back panel. A pad is provided on the side wall of the back panel facing the buckle panel. An installation plate is movably provided on the side wall of the pad. A cotton swab is provided on the side wall of the installation plate. The cotton swab overlaps with the sponge board.

[0010] The fluid replenishment mechanism includes a fluid replenishment tank and an installation box. Both the fluid replenishment tank and the installation box contain medication. The installation box and the fluid replenishment tank are connected by a connecting pipe. An installation groove is provided on the side wall of the back plate away from the buckle plate. The installation box is installed in the installation groove. A fluid replenishment pipe is provided on the side wall of the installation box. The fluid replenishment pipe passes through the pad and the side wall of the installation plate and is connected to the fluid replenishment cotton strip.

[0011] By using the above technical solution, a wrapping mechanism and a corresponding liquid replenishment mechanism are set at the wall penetration point of the cable body, thereby providing physical and chemical double protection for the bending and wall penetration points of the cable body, and extending the protection time against rodent and ant bites.

[0012] Furthermore, the end of the pad that contacts the cable body is arc-shaped, and the end of the mounting plate that contacts the cable body is also arc-shaped. A perforation is provided on one side wall of the pad, and the liquid replenishment tube extends out from the perforation. A magnetic sheet is provided on the other side wall of the pad, and the mounting plate is made of magnetic metal.

[0013] With the above technical solution, when the cable body is placed between the buckle plate and the back plate, the pad will abut against the side wall of the cable body, thereby playing a certain role in fixing and limiting. At the same time, the mounting box installed on the side wall of the back plate will pass through the pad through the liquid replenishment pipe, thereby delivering the liquid to the inside of the mounting plate installed on the pad.

[0014] Furthermore, the mounting plate has a cavity, and the mounting plate has a through hole on the side wall facing the perforation. A sealing ring is provided on the side wall of the cavity with the through hole. The size of the through hole is the same as that of the perforation and the position of the through hole corresponds to the position of the perforation. A protruding rod is fixedly provided on the side wall of the cavity. One end of the fluid replenishing cotton strip is placed inside the cavity, and the other end passes through the side wall of the cavity and overlaps with the sponge plate.

[0015] With the above technical solution, after the mounting plate is installed, the liquid replenishment tube will pass through the through hole into the cavity. The protruding rod in the cavity will transport the liquid medicine in the mounting box into the cavity. Therefore, the liquid replenishment cotton strip set in the cavity will be soaked with the liquid medicine. Since the liquid replenishment cotton strip overlaps with the sponge board, the soaked liquid replenishment cotton strip will transport the liquid medicine to the sponge board, thereby continuously replenishing the sponge board with liquid medicine and ensuring long-term rodent and ant prevention.

[0016] Furthermore, a liquid chamber is provided inside the mounting box, and the liquid replenishment pipe is located on the side wall of the mounting box facing the back plate. The liquid replenishment pipe is connected to the liquid chamber. A short pipe is also installed on the side wall of the mounting box, and the short pipe is also connected to the liquid chamber.

[0017] Through the above technical solution, the liquid replenishment pipe and short pipe installed on the side wall of the installation box deliver the liquid to two locations. One of them delivers the liquid to the sponge board outside the cable body, and the other part delivers it to the sponge sheet inside the back plate, thereby providing protection for both the cable body and the wrapping mechanism.

[0018] Furthermore, the mounting box has locking blocks on both sides of its sidewalls, and the mounting groove has protrusions at the corresponding positions on both sides of its sidewalls and the locking blocks. The locking blocks have an arc-shaped design on the side facing the protrusions.

[0019] The above technical solution allows the mounting box to be easily installed into the mounting slot. The design of the locking block and the protrusion is only one way to achieve the locking mechanism. In actual production, other locking mechanisms can also be used.

[0020] Furthermore, both the replenishing tube and the short tube are rotatably connected to baffles. A limiting ring is provided on the side wall of the replenishing tube away from the liquid cavity, and a limiting ring is also provided on the side wall of the short tube away from the liquid cavity. The outer diameter of the baffle is larger than the inner diameter of the limiting ring.

[0021] Through the above technical solution, the design of the baffle can ensure that the medicine will not flow out from the replenishment pipe and the short pipe when the installation box is not installed. The baffle can only rotate in the direction of the installation box. Therefore, when the installation box contains medicine, the pressure of the medicine will press the baffle against the side wall of the limiting ring, thereby preventing the medicine from flowing out.

[0022] Furthermore, a medicine liquid chamber is provided in the back plate, a through tube is provided in the mounting groove, a protective ring is fixedly provided on the side wall of the through tube, the through tube passes through the side wall of the short tube and abuts against the side wall of the baffle, a medicine liquid tank is provided at the bottom of the medicine liquid chamber, the other end of the through tube is guided to the medicine liquid tank, a sponge sheet is installed on the side wall of the medicine liquid chamber, and several forked cotton strips extend from the medicine liquid tank, with different branches of the forked cotton strips overlapping on different positions of the sponge sheet.

[0023] With the above technical solution, the protective ring can ensure that the medicine will not leak out from the gap between the two after the tube is inserted into the short tube. The medicine entering the medicine tank through the tube will wet the forked cotton strip, and then wet different positions of the sponge sheet through the forked cotton strip. The sponge sheet will be placed at the edge of the back plate, thus blocking the front line of rodents and ants gnawing on the back plate.

[0024] Furthermore, the end of the connecting pipe extending into the liquid chamber is bent horizontally, and a water outlet pipe is fixedly installed at the end of the connecting pipe away from the replenishment tank. A sleeve is fixedly installed outside the water outlet pipe, and the bottom of the sleeve is connected to the replenishment pipe. A rubber gasket is fixedly installed in the sleeve, and the side wall of the rubber gasket abuts against the side wall of the water outlet pipe. A movable piece is installed in the middle of the rubber gasket. A movable seat is opened on the side wall of the sleeve away from the water outlet pipe. A push rod is slidably connected in the movable seat. One end of the push rod abuts against the side wall of the movable piece, and the other end passes through the sleeve through the movable seat. A fixing block is fixedly installed on the side wall of the sleeve. A long plate is rotatably connected to the side wall of the fixing block. A lifting block is fixedly installed on the side wall of the long plate. A push rod is fixedly installed on the side wall of the lifting block. A semi-circular sleeve is fixedly installed on the side wall of the long plate away from the fixing block. A float is installed inside the semi-circular sleeve, and the float floats on the surface of the liquid.

[0025] With the above technical solution, after the liquid medicine enters the liquid chamber, the height of the liquid medicine will affect the height of the float in real time. When the liquid medicine height is sufficient, the semi-circular sleeve at the top of the float will drive the long plate to rotate. The push rod set at the top of the long plate will push the stop rod. The stop rod pushes the movable plate to block the water outlet pipe, which can prevent the liquid medicine in the replenishment tank from being replenished into the installation box.

[0026] Furthermore, the height of the replenishment tank is greater than the height of the back plate, the side wall of the replenishment tank at the end connected to the connecting pipe is designed to be inclined, and a lid is provided at the end of the replenishment tank away from the connecting pipe.

[0027] With the above technical solution, the medicine in the replenishment tank needs to enter the installation box under the action of gravity and then replenish various positions. Therefore, the replenishment tank needs to be located at a high position. At the same time, in order to make it easier to replenish the medicine in the replenishment tank, a box cover can be installed on the top of the replenishment tank. In actual production, the box cover needs to adopt a more stringent sealing method to prevent unauthorized personnel from opening it by mistake.

[0028] A manufacturing process for a rodent- and ant-proof power cable includes the following specific steps:

[0029] S1. Multiple annealed single wires are twisted together according to regulations, and then preheated insulation material is continuously and evenly extruded onto the twisted single wires through an extruder. After cooling, the cable body is formed.

[0030] S2. Wrap the sponge board around the outside of the cable body, and then insert both of them together between the buckle plate and the back plate, so that the side wall of the cable body abuts against the side wall of the pad. Then install the mounting plate onto the pad, so that the liquid replenishing tube passes through the through hole, and ensure that the liquid replenishing cotton strip overlaps with the sponge board. Then install the wall-mounting plate at the through hole position.

[0031] S3. Under the action of gravity, the medicine will enter the installation box from the replenishment tank. The float will float up to a certain height with the medicine. The semi-circular sleeve on the top of the float will drive the long plate to rotate around the fixed block, which will cause the push rod to squeeze the abutment rod. The abutment rod will press the movable plate under the action of the push rod, which will block the water outlet pipe and stop the water outlet pipe from outputting medicine.

[0032] S4. The liquid medicine in the installation box will be output through the replenishment tube and the short tube. The liquid medicine through the replenishment tube will enter the cavity inside the installation plate, and then wet the replenishment cotton strip. Since the replenishment cotton strip overlaps with the sponge plate, the wetted replenishment cotton strip continuously replenishes the liquid medicine to the sponge plate.

[0033] S5. The liquid medicine passing through the short tube will enter the liquid medicine tank through the tube. The forked cotton strips set in the liquid medicine tank will be soaked with the liquid medicine, and then the liquid medicine will be replenished to different positions of the sponge through the forks.

[0034] The beneficial effects of this invention are as follows:

[0035] (1) The present invention provides physical and chemical double protection for the bending and wall-penetrating positions of the cable body by setting a wrapping mechanism and a corresponding liquid replenishment mechanism at the wall-penetrating position of the cable body. The buckle plate and back plate can provide the first layer of protection for the cable body, while the sponge plate soaked in medicine wrapped around the outside of the cable body will provide the second layer of protection. Moreover, due to the existence of the liquid replenishment mechanism, the medicine inside the sponge plate is continuously replenished, thereby making the protection against rodents and ants for a longer time.

[0036] (2) The present invention provides a liquid replenishment pipe and a short pipe on the side wall of the installation box. The liquid replenishment pipe and the short pipe can respectively deliver the liquid to two positions. One of them delivers the liquid to the sponge board outside the cable body, and the other part of the liquid will be delivered to the sponge sheet inside the back plate, thereby providing protection for both the cable body and the wrapping mechanism. The liquid entering the liquid tank through the pipe will wet the forked cotton strip, and then wet different positions of the sponge sheet through the forked cotton strip. The sponge sheet set at the edge of the back plate will block the front line of rodents and ants gnawing on the back plate.

[0037] (3) The present invention sets up a component for automatic opening and closing of liquid replenishment in the liquid cavity. After the liquid enters the liquid cavity, the height of the liquid will affect the height of the float in real time. When the liquid height is sufficient, the semi-circular sleeve at the top of the float will drive the long plate to rotate. The push rod set at the top of the long plate will push the abutment rod. The abutment rod pushes the movable piece to block the water outlet pipe, which can prevent the liquid in the replenishment tank from being replenished into the installation box, thus achieving the effect of automatic opening and closing of liquid replenishment.

[0049] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0050] like Figures 1-10As shown, a rodent-proof power cable in this embodiment includes a cable body 1. The cable body 1 includes an insulation layer 2 and several single wires 3. The several single wires 3 are twisted together. The insulation layer 2 is sleeved and installed on the outside of the several single wires 3. A wall-mounted plate 4 is provided on the side wall of the insulation layer 2. The wall-mounted plate 4 is directly installed at the position where the cable body 1 passes through the wall, thereby preventing rodents and ants from entering the building through the perforation 16.

[0051] For details regarding parcel delivery organizations, please refer to [link / reference]. Figures 2-4 The wrapping mechanism includes a back panel 5 and a snap-on plate 6. The snap-on plate 6 has an arched cross-section and is snapped onto the back panel 5. A sponge board 7 is installed inside the snap-on plate 6. The cable body 1 is located between the snap-on plate 6 and the back panel 5. The sponge board 7 adheres to the cable body 1 and fills the space between the snap-on plate 6 and the back panel 5, thus preventing rodents and ants from directly gnawing on the cable body 1. The side wall of the wall-mounting panel 4 is fixedly connected to the side wall of the back panel 5. A pad 8 is provided on the side wall of the back panel 5 facing the snap-on plate 6. The end of the pad 8 that contacts the cable body 1 has an arc-shaped design. The end of the mounting plate 9 that contacts the cable body 1 also has an arc-shaped design. The pad 8 has a perforation 16 on one side wall, through which the liquid replenishment tube 15 extends. The other side wall of the pad 8 is provided with a magnetic sheet 17. The mounting plate 9 is made of magnetic metal. When the cable body 1 is placed between the buckle plate 6 and the back plate 5, the pad 8 will abut against the side wall of the cable body 1, thereby achieving a certain fixing and limiting effect. At the same time, the mounting box 12 installed on the side wall of the back plate 5 will pass through the pad 8 through the liquid replenishment tube 15, thereby delivering the medicine to the inside of the mounting plate 9 installed on the pad 8. After the magnetic sheet 17 and the mounting plate 9 are installed, they will automatically attract each other, thereby ensuring the stability of the connection.

[0052] The side wall of the pad 8 is movably provided with an installation plate 9, and the side wall of the installation plate 9 is provided with a liquid replenishing cotton strip 10. The liquid replenishing cotton strip 10 overlaps with the sponge plate 7. The liquid replenishing cotton strip 10 will share the absorbed medicine into the sponge plate 7, thereby continuously replenishing the sponge plate 7 and ensuring the protective effect.

[0053] from Figure 3As can be seen, the mounting plate 9 has a cavity. A through hole 18 is provided on the side wall of the mounting plate 9 facing the perforation 16. A sealing ring 19 is provided on the side wall of the cavity with the through hole 18. The size of the through hole 18 is the same as that of the perforation 16, and the position of the through hole 18 corresponds to the position of the perforation 16. A protruding rod 20 is fixedly provided on the side wall of the cavity. One end of the liquid replenishing cotton strip 10 is placed inside the cavity, and the other end passes through the side wall of the cavity and overlaps with the sponge plate 7. After the mounting plate 9 is installed, the liquid replenishing tube 15 will pass through the through hole 18 and enter the cavity. The protruding rod 20 in the cavity will transport the medicine in the mounting box 12 into the cavity. Therefore, the liquid replenishing cotton strip 10 placed in the cavity will be wetted by the medicine. Since the liquid replenishing cotton strip 10 overlaps with the sponge plate 7, the wet liquid replenishing cotton strip 10 will transport the medicine to the sponge plate 7, thereby continuously replenishing the sponge plate 7 and ensuring long-term rodent and ant prevention.

[0054] For fluid replacement facilities, please refer to Figure 6 The replenishment mechanism includes a replenishment tank 11 and an installation box 12. Both the replenishment tank 11 and the installation box 12 contain liquid medicine. The installation box 12 and the replenishment tank 11 are connected by a connecting pipe 13. The height of the replenishment tank 11 is greater than the height of the back plate 5. The side wall of the replenishment tank 11 connected to the connecting pipe 13 is designed with an inclination. A lid 43 is provided at the end of the replenishment tank 11 away from the connecting pipe 13. The liquid medicine in the replenishment tank 11 needs to enter the installation box 12 under the action of gravity and then replenish various positions. Therefore, the position of the replenishment tank 11 needs to be high. At the same time, in order to make it easier to replenish the liquid medicine in the replenishment tank 11, a lid 43 can be provided on the top of the replenishment tank 11. In actual production, the lid 43 needs to adopt a more stringent sealing method to prevent unauthorized personnel from opening it by mistake.

[0055] Combination Figure 4 and Figure 6 As shown, the back panel 5 has a mounting groove 14 on the side wall away from the buckle plate 6. The mounting box 12 is installed in the mounting groove 14. A liquid replenishment tube 15 is provided on the side wall of the mounting box 12. The liquid replenishment tube 15 passes through the pad block 8 and the side wall of the mounting plate 9 and is connected to the liquid replenishment cotton strip 10. The two side walls of the mounting box 12 are respectively provided with locking blocks 22. The two side walls of the mounting groove 14 are provided with protrusions 23 at the corresponding positions of the locking blocks 22. The side of the locking block 22 facing the protrusion 23 has an arc design. The locking design allows the mounting box 12 to be easily installed into the mounting groove 14. The design of the locking block 22 and the protrusion 23 is only one way to achieve locking. In actual production, other locking methods can be replaced.

[0056] The mounting box 12 has a liquid chamber inside, and the liquid replenishment pipe 15 is set on the side wall of the mounting box 12 facing the back plate 5. The liquid replenishment pipe 15 is connected to the liquid chamber. A short pipe 21 is also installed on the side wall of the mounting box 12, and the short pipe 21 is also connected to the liquid chamber.

[0057] from Figure 7As can be seen, both the replenishment tube 15 and the short tube 21 are rotatably connected to baffles 24. A limit ring 25 is provided on the side wall of the replenishment tube 15 away from the liquid cavity, and a limit ring 25 is also provided on the side wall of the short tube 21 away from the liquid cavity. The outer diameter of the baffle 24 is larger than the inner diameter of the limit ring 25. The design of the baffle 24 can ensure that the medicine will not flow out from the replenishment tube 15 and the short tube 21 when the installation box 12 is not installed. The baffle 24 can only rotate in the direction of the installation box 12. Therefore, when the installation box 12 contains medicine, the pressure of the medicine will press the baffle 24 against the side wall of the limit ring 25, thereby preventing the medicine from flowing out.

[0058] Combination Figure 4 and Figure 5 As shown, a medicine liquid chamber is provided in the back plate 5, and a through tube 26 is provided in the mounting groove 14. A protective ring 27 is fixedly provided on the side wall of the through tube 26. The through tube 26 passes through the side wall of the short tube 21 and abuts against the side wall of the baffle 24. A medicine liquid tank 28 is provided at the bottom of the medicine liquid chamber. The other end of the through tube 26 is guided to the medicine liquid tank 28. A sponge sheet 29 is installed on the side wall of the medicine liquid chamber. Several forked cotton strips 30 extend from the medicine liquid tank 28. Different branches of the forked cotton strips 30 overlap at different positions on the sponge sheet 29. The protective ring 27 can ensure that the medicine liquid will not flow out from the gap between the two after the through tube 26 is inserted into the short tube 21. The medicine liquid entering the medicine liquid tank 28 from the through tube 26 will wet the forked cotton strips 30, and then wet different positions of the sponge sheet 29 through the forked cotton strips 30. The sponge sheet 29 will be set at the edge of the back plate 5, thus blocking the front line of rodents and ants gnawing on the back plate 5.

[0059] from Figures 8-10 As can be seen, the end of the connecting pipe 13 extending into the liquid chamber is turned horizontally. The horizontally positioned connecting pipe 13 can prevent the liquid from flowing directly into the installation box 12. A water outlet pipe 31 is fixedly installed at the end of the connecting pipe 13 away from the replenishment tank 11. A sleeve 32 is fixedly installed outside the water outlet pipe 31. The bottom of the sleeve 32 is connected to the replenishment pipe 15. A rubber gasket 33 is fixedly installed in the sleeve 32. The side wall of the rubber gasket 33 abuts against the side wall of the water outlet pipe 31. A movable piece 34 is installed in the middle of the rubber gasket 33. The movable piece 34 allows the abutment rod 36 to freely choose whether to block the water outlet pipe 31. 2. A movable seat 35 is provided on the side wall away from the outlet pipe 31. A push rod 36 is slidably connected in the movable seat 35. One end of the push rod 36 abuts against the side wall of the movable plate 34, and the other end passes through the sleeve 32 through the movable seat 35. A fixing block 37 is fixedly installed on the side wall of the sleeve 32. A long plate 38 is rotatably connected to the side wall of the fixing block 37. A lifting block 39 is fixedly installed on the side wall of the long plate 38. A push rod 40 is fixedly installed on the side wall of the lifting block 39. A semi-circular sleeve 41 is fixedly installed on the side wall away from the fixing block 37 of the long plate 38. A float ball 42 is installed inside the semi-circular sleeve 41 and floats on the surface of the liquid medicine.

[0060] After the medicine enters the liquid chamber, the height of the medicine will affect the height of the float 42 in real time. When the medicine height is sufficient, the semi-circular sleeve 41 at the top of the float 42 will drive the long plate 38 to rotate. The push rod 40 set at the top of the long plate 38 will push the stop rod 36. The stop rod 36 pushes the movable piece 34 to block the water outlet pipe 31, which can prevent the medicine in the replenishment tank 11 from being replenished into the installation box 12.

[0061] The manufacturing process of rodent- and ant-proof power cables includes the following specific steps:

[0062] S1. Multiple annealed single wires 3 are twisted together according to regulations, and then preheated insulation material is continuously and evenly extruded onto the twisted single wires 3 through an extruder. After cooling, the cable body 1 is formed.

[0063] S2. Wrap the sponge board 7 around the outside of the cable body 1, and then insert both of them together between the buckle plate 6 and the back plate 5, so that the side wall of the cable body 1 abuts against the side wall of the pad 8. Then install the mounting plate 9 onto the pad 8, so that the liquid replenishing tube 15 passes through the through hole 18, and ensure that the liquid replenishing cotton strip 10 overlaps with the sponge board 7. Then install the wall-mounted plate 4 at the through hole position.

[0064] S3. Under the action of gravity, the medicine will enter the installation box 12 from the replenishment tank 11. The float 42 will float up to a certain height with the medicine. The semi-circular sleeve 41 at the top of the float 42 will drive the long plate 38 to rotate around the fixed block 37, which will cause the push rod 40 to squeeze the abutment rod 36. The abutment rod 36 will press the movable plate 34 under the action of the push rod 40, which will block the water outlet pipe 31 and stop the water outlet pipe 31 from outputting medicine.

[0065] S4. The liquid medicine in the installation box 12 will be output through the replenishment pipe 15 and the short pipe 21. The liquid medicine through the replenishment pipe 15 will enter the cavity inside the installation plate 9, and then wet the replenishment cotton strip 10. Since the replenishment cotton strip 10 overlaps with the sponge plate 7, the wetted replenishment cotton strip 10 will continuously replenish the liquid medicine to the sponge plate 7.

[0066] S5. The liquid medicine passing through the short tube 21 will enter the liquid medicine tank 28 through the through tube 26. The forked cotton strip 30 set in the liquid medicine tank 28 will be soaked with the liquid medicine, and then the liquid medicine will be replenished to different positions of the sponge sheet 29 through the forks.

[0067] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
