Description

Technical Field

[0001] The invention relates to a low-voltage cable, in particular to a low-voltage cable with a protective structure applied in the technical field of cables. Background Art

[0002] Power cables are cables used to transmit and distribute electrical energy. They are widely used in urban underground power grids, power station lead-out lines, and internal power supply for industrial and mining enterprises. Low-voltage power cables are a type of power cable used to transmit and distribute low-voltage electrical energy.

[0003] During the use of low-voltage cables, the cables will inevitably be stretched. When the cables are subjected to a large tensile force, they are easily deformed and damaged. Low-voltage cables in the prior art generally do not have corresponding protective structures, which makes the cables easily deformed and damaged due to large tensile forces, and the safety is low. Therefore, we propose a low-voltage cable with a protective structure. Summary of the invention

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the low-voltage cables in the prior art generally do not have corresponding protective structures, which causes the cables to be easily deformed and damaged due to large pulling forces, and the safety is low.

[0005] In order to solve the above problems, the present invention provides a low-voltage cable with a protective structure, including a low-voltage cable body and an anti-tension damage protection mechanism, the anti-tension damage protection mechanism includes an anti-damage buffer box, a semi-cylindrical curved cable column is movably arranged in the anti-damage buffer box, a detection and pulling support tube is penetrated and embedded in the anti-damage buffer box, a distance measuring detection and pulling rod is fixedly connected to one end of the curved cable column close to the detection and pulling support tube, the distance measuring detection and pulling rod penetrates the outer wall of the detection and pulling support tube and extends to the inside of the detection and pulling support tube, and the distance measuring detection and pulling rod is slidably connected to the outer wall of the detection and pulling support tube, a distance sensor is fixedly installed in the detection and pulling support tube, and the distance sensor is located just in front of the distance measuring detection and pulling rod.

At the same time, the anti-loss intelligent alarm will also activate the alarm to make the alarm sound to warn and remind relevant personnel, prompting the relevant personnel to stop pulling the low-voltage cable body, thereby further preventing the low-voltage cable body from being deformed and damaged due to a large tensile force, thereby greatly improving the safety of the low-voltage cable.

[0007] As a further improvement of the present application, elastic fixed rod ropes are fixedly connected to the inner walls on both sides of the left and right sides of the anti-damage buffer box, and the other end of the elastic fixed rod rope is fixedly connected to the distance measuring detection pull rod. The elastic fixed rod rope can play a certain fixing role on the distance measuring detection pull rod, and can further prevent the alarm function of the anti-tension damage protection mechanism from being triggered by mistake. The top of the anti-damage buffer box is arranged to be in an open shape, and the top of the anti-damage buffer box is detachably fixedly connected with a box cover matching it, so that the low-voltage cable body can be easily placed in the anti-damage buffer box, and the box cover is made of transparent material, so that the situation inside the anti-damage buffer box is easy to observe.

[0008] As a further improvement of the present application, the anti-strain damage protection mechanism also includes a pair of protection and consumption reduction components respectively arranged on the left and right sides of the anti-damage buffer box, the protection and consumption reduction components include a protection support box fixedly mounted on the outer wall of the anti-damage buffer box, a curved cable plate rotatably connected to the protection support box is arranged in the protection support box, a rotating groove matching the curved cable plate is opened on the outer wall of the protection support box, an elastic airbag is fixedly installed in the protection support box, the elastic airbag is filled with air, and the elastic airbag is made of elastic material.

[0010] As a further improvement of the present application, an elastic buffer membrane is embedded through the outer wall of the trigger adjustment cylinder away from the air guide tube, and the start button is fixedly mounted on the elastic buffer membrane to prevent the start button from being squeezed and damaged. A pair of elastic restoring ropes are fixedly connected between the touch button piston plate and the inner wall of the trigger adjustment cylinder. The elastic restoring ropes are located on the side of the touch button piston plate away from the start button, so that the touch button piston plate can be automatically reset.

[0011] As another improvement of the present application, a cable cutting assembly is further provided in the loss-preventing buffer box, and a cable cutting control module is further provided in the loss-preventing intelligent alarm device. The cable cutting assembly comprises a support plate arranged in an L shape, the support plate is fixedly connected to the curved cable column, an electric telescopic rod is fixedly mounted on the support plate, a cable cutting blade is fixedly connected to the output end of the electric telescopic rod, and the cable cutting blade is located on the side of the low-voltage cable body away from the curved cable column.

[0012] As another improvement and supplement to the present application, a cable cutting distance threshold is reasonably set through the threshold setting module, and the distance data monitored by the distance sensor is also transmitted to the cable cutting control module in real time. When the distance between the distance sensor and the distance measuring detection rod is reduced to the cable cutting distance threshold, the cable cutting control module will start the electric telescopic rod to push the cable cutting blade to cut the low-voltage cable body, so that the anti-tension protection mechanism also has a cutting protection function, which can automatically cut off the low-voltage cable body when the low-voltage cable body is subjected to a large pulling force.

[0013] As another improvement supplement to the present application, the cable cutting distance threshold is smaller than the alarm distance threshold, and the distance between the distance measuring detection rod and the distance sensor is larger than the distance between the curved cable column and the detection support tube, so that the cutting protection function of the anti-tension damage protection mechanism can be selectively turned on or off depending on the situation.

[0014] As another improved supplement to the present application, the cable cutting blade is made of insulating material to prevent leakage, and a pair of anti-miscutting baffles are fixedly installed on the electric telescopic rod. The pair of anti-miscutting baffles are respectively located on the left and right sides of the cable cutting blade. The distance between the anti-miscutting baffle and the curved cable column is smaller than the distance between the cable cutting blade and the curved cable column. The anti-miscutting baffle can protect the low-voltage cable body and prevent the low-voltage cable body from accidentally contacting the cable cutting blade and causing damage to the low-voltage cable body.

DETAILED DESCRIPTION

[0018] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0019] The first implementation method: Figure 1-6A low-voltage cable with a protective structure is shown, including a low-voltage cable body 001 and an anti-tension damage protection mechanism, the anti-tension damage protection mechanism includes an anti-damage buffer box 201, a semi-cylindrical curved cable column 202 is movably arranged in the anti-damage buffer box 201, a detection and pulling support tube 203 is penetrated and embedded in the anti-damage buffer box 201, and a distance detection and pulling rod 204 is fixedly connected to the end of the curved cable column 202 close to the detection and pulling support tube 203, and the distance detection and pulling rod 204 penetrates the outer wall of the detection and pulling support tube 203 and extends to the inside of the detection and pulling support tube 203, and the distance detection and pulling rod 204 is slidably connected to the outer wall of the detection and pulling support tube 203, a distance sensor 205 is fixedly installed in the detection and pulling support tube 203, and the distance sensor 205 is located directly in front of the distance detection and pulling rod 204, and a distance sensor 205 is provided on the anti-damage buffer box 201. With respect to the cable groove 206, the low-voltage cable body 001 passes through the cable groove 206 and is slidably connected therewith, part of the low-voltage cable body 001 is sleeved on the curved cable column 202 and is slidably connected therewith, part of the low-voltage cable body 001 in the anti-damage buffer box 201 is U-shaped, an alarm 207 is fixedly installed on the outer wall of the anti-damage buffer box 201, an anti-damage intelligent alarm 005 is fixedly installed in the anti-damage buffer box 201, a power supply 208 is fixedly installed in the anti-damage buffer box 201, the distance sensor 205, the alarm 207, and the anti-damage intelligent alarm 005 are all electrically connected to the power supply 208, a threshold setting module and a Chala alarm control module are provided in the anti-damage intelligent alarm 005, the threshold setting module and the distance sensor 205 are all signal-connected to the Chala alarm control module, and the Chala alarm control module is signal-connected to the alarm 207.

[0020] When the low-voltage cable body 001 is subjected to a large tensile force, under the action of the tensile force, the low-voltage cable body 001 in the anti-damage buffer box 201 will tend to be straightened. After the low-voltage cable body 001 in the anti-damage buffer box 201 is straightened, the low-voltage cable body 001 may be deformed and damaged under the action of the tensile force. Therefore, the anti-tension damage protection mechanism can play a buffering protection role, and to a large extent prevent the low-voltage cable body 001 from being deformed and damaged due to the large tensile force. In addition, those skilled in the art can reasonably set an alarm distance threshold through the threshold setting module according to the situation, start the distance sensor 205 and the anti-damage intelligent alarm 005, and the distance sensor 205 can monitor in real time. The distance between the distance sensor 205 and the distance detection rod 204 is measured, and the distance data monitored by the distance sensor 205 will be transmitted to the check and pull control module in real time. In the process that the low-voltage cable body 001 in the anti-damage buffer box 201 tends to be straightened, the check and pull support cylinder 203 will be pushed, causing the distance detection rod 204 to approach the distance sensor 205. When the distance between the distance sensor 205 and the distance detection rod 204 is reduced to the alarm distance threshold, the check and pull control module will start the alarm 207, causing the alarm 207 to sound an alarm. The alarm sound emitted by the alarm 207 can serve as a warning and reminder, causing the person pulling the low-voltage cable body 001 to stop. The low-voltage cable body 001 can be prevented from being deformed and damaged due to a large pulling force. Therefore, the anti-tension damage protection mechanism is set up, so that the anti-tension damage protection mechanism can provide a buffer protection for the low-voltage cable body 001. When the low-voltage cable body 001 is subjected to a large pulling force, it can protect the low-voltage cable body 001 to a large extent and prevent the low-voltage cable body 001 from being deformed and damaged. The anti-tension damage protection mechanism also has an alarm function. When the low-voltage cable body 001 is subjected to a large pulling force, the anti-loss intelligent alarm device 005 will activate the alarm 207 to make the alarm 207 sound an alarm to warn and remind relevant personnel, so as to prompt relevant personnel The staff stops pulling the low-voltage cable body 001, thereby further preventing the low-voltage cable body 001 from being deformed and damaged due to a large pulling force, greatly improving the safety of the low-voltage cable. In addition, because the alarm 207 will not be activated until the distance between the distance sensor 205 and the ranging detection rod 204 is reduced to the alarm distance threshold, it is difficult to reduce the distance between the distance sensor 205 and the ranging detection rod 204 to the alarm distance threshold when the low-voltage cable body 001 is pulled normally, thereby preventing the alarm function of the anti-tension damage protection mechanism from being mistakenly triggered, causing trouble to relevant personnel, and greatly improving the practicability and reliability of the anti-tension damage protection mechanism.

[0021] See also Figure 1 and Figure 3Elastic fixed rod ropes 209 are fixedly connected to the inner walls on both sides of the left and right sides of the anti-damage buffer box 201, and the other end of the elastic fixed rod rope 209 is fixedly connected to the distance measuring detection pull rod 204. The elastic fixed rod rope 209 can play a certain fixing role on the distance measuring detection pull rod 204, and can further prevent the alarm function of the anti-tension damage protection mechanism from being triggered by mistake. The top of the anti-damage buffer box 201 is set to an opening shape, and the top of the anti-damage buffer box 201 is detachably fixedly connected with a box cover 210 matching it, so that the low-voltage cable body 001 can be easily placed in the anti-damage buffer box 201, and the box cover 210 is made of transparent material, so that the situation in the anti-damage buffer box 201 is easy to observe.

[0022] See also Figure 1-2 and Figure 4-5 The anti-strain damage protection mechanism also includes a pair of protection and consumption reduction components respectively arranged on the left and right sides of the anti-damage buffer box 201, the protection and consumption reduction components include a protection support box 301 fixedly installed on the outer wall of the anti-damage buffer box 201, a curved cable plate 302 rotatably connected to the protection support box 301 is arranged in the protection support box 301, and a rotation slide 303 matching the curved cable plate 302 is opened on the outer wall of the protection support box 301, an elastic airbag 304 is fixedly installed in the protection support box 301, the elastic airbag 304 is filled with air, and the elastic airbag 304 is made of elastic material, the rotation slide 303 is set to an L shape, the curved cable plate 302 passes through the rotation slide 303 and slides with the rotation slide 303 The curved cable plate 302 is attached to the elastic airbag 304, part of the low-pressure cable body 001 is located between the curved cable plate 302 and the anti-damage buffer box 201 and is bent, the elastic airbag 304 is located on the side of the curved cable plate 302 close to the anti-damage buffer box 201, and a trigger adjustment cylinder 305 is fixedly installed in the protection support box 301, an air duct 306 is connected between the trigger adjustment cylinder 305 and the elastic airbag 304, a touch button piston plate 307 which is slidably and sealedly connected thereto is provided in the trigger adjustment cylinder 305, a start button 308 is fixedly installed on the side of the touch button piston plate 307 away from the air duct 306, and the start button 308 is connected to the anti-damage intelligent alarm 005 and the distance sensor 205 signal.

[0023] Under normal circumstances (when the low-pressure cable body 001 is not subjected to a large tensile force), the elastic airbag 304 can play a fixing role on the curved cable plate 302, limiting the rotation of the curved cable plate 302, so that the curved cable plate 302 can play a fixing role on the part of the low-pressure cable body 001 between it and the anti-damage buffer box 201, so that this part of the low-pressure cable body 001 can remain in a bent state. When the low-pressure cable body 001 is subjected to a large tensile force, under the action of the tensile force, the space between the curved cable plate 302 and the anti-damage buffer box 201 This part of the low-voltage cable body 001 will be straightened first, and then the low-voltage cable body 001 in the anti-damage buffer box 201 will be straightened. Therefore, the protection-enhancing and consumption-reducing components can enhance the buffering protection effect of the anti-tension protection mechanism, and further prevent the low-voltage cable body 001 from being deformed and damaged due to a large tensile force. In addition, during the straightening process of this part of the low-voltage cable body 001 between the curved cable plate 302 and the anti-damage buffer box 201, the curved cable plate 302 will squeeze the elastic airbag 304, causing part of the air in the elastic airbag 304 to be compressed. The air flows into the trigger adjustment cylinder 305 through the air guide tube 306, and the inflow of air pushes the touch button piston plate 307, causing the touch button piston plate 307 to squeeze the trigger start button 308, thereby waking up the anti-damage intelligent alarm 005 and the distance sensor 205, so that the anti-damage intelligent alarm 005 and the distance sensor 205 can be in a low-energy standby state at ordinary times, and when the low-voltage cable body 001 is subjected to a large pulling force, the anti-damage intelligent alarm 005 and the distance sensor 205 will be automatically awakened, thereby ensuring that the alarm function of the anti-tension damage protection mechanism can be successfully triggered. Therefore, through the setting of the protection and consumption reduction component, the protection and consumption reduction component can not only enhance the buffering protection effect of the anti-tension damage protection mechanism, further prevent the low-voltage cable body 001 from being deformed and damaged due to a large pulling force, but also greatly reduce the energy consumption of the anti-tension damage protection mechanism while ensuring that the alarm function of the anti-tension damage protection mechanism can be successfully triggered, thereby improving the endurance of the anti-tension damage protection mechanism, and further improving the practicality and reliability of the anti-tension damage protection mechanism.

[0024] It should be noted that the low-voltage cable body 001 at the anti-strain protection mechanism needs to be bent. When bending the low-voltage cable body 001, care should be taken not to exceed the maximum bending degree that the low-voltage cable body 001 can withstand.

[0025] See also Figure 5An elastic buffer membrane 309 is embedded through the outer wall of the trigger adjustment cylinder 305 away from the air guide tube 306, and the start button 308 is fixedly installed on the elastic buffer membrane 309. After the touch button piston plate 307 squeezes the trigger start button 308, if the air continues to push the touch button piston plate 307, it will cause the elastic buffer membrane 309 to bulge outward from the trigger adjustment cylinder 305, thereby playing a buffering role, protecting the start button 308 and preventing the start button 308 from being squeezed and damaged. A pair of restoring elastic ropes 310 are fixedly connected between the touch button piston plate 307 and the inner wall of the trigger adjustment cylinder 305. The restoring elastic ropes 310 are located on the side of the touch button piston plate 307 away from the start button 308, so that the touch button piston plate 307 can be automatically reset.

[0026] The second implementation method: Figure 7-9 A low-voltage cable with a protective structure is shown. Different from the first embodiment, a cable cutting assembly is further provided in the anti-loss buffer box 201, and a cable cutting control module is further provided in the anti-loss intelligent alarm 005. The cable cutting assembly includes an L-shaped support plate 401, the support plate 401 is fixedly connected to the curved cable column 202, an electric telescopic rod 402 is fixedly installed on the support plate 401, and a cable cutting blade 403 is fixedly connected to the output end of the electric telescopic rod 402. The cable cutting blade 403 is located on the side of the low-voltage cable body 001 away from the curved cable column 202. The threshold setting module and the distance sensor 205 are both connected to the cable cutting control module signal, the cable cutting control module is connected to the electric telescopic rod 402 signal, and the check alarm module is electrically connected to the power supply 208.

[0027] When the low-voltage cable is subjected to a large pulling force, it is not only easy to cause the cable to be deformed and damaged, but in severe cases, it may also cause the cable to be broken. Once the cable is broken, it will cause the cable to be scrapped. Even if the broken cable is docked, it is difficult to continue using it and the cable needs to be replaced. If the low-voltage cable body 001 can be cut off in time, although the cut low-voltage cable body 001 needs to be docked afterwards, the cable can be prevented from being scrapped. In this embodiment, the technicians in this field can reasonably set a cable cutting distance threshold through the threshold setting module according to the situation, and the distance data monitored by the distance sensor 205 will also be transmitted to the The cable cutting control module, when the distance between the distance sensor 205 and the distance measuring detection rod 204 is reduced to the cable cutting distance threshold, the cable cutting control module will start the electric telescopic rod 402, so that the electric telescopic rod 402 pushes the cable cutting blade 403 to cut the low-voltage cable body 001. Therefore, by selecting the combined setting of the cable cutting assembly, the cable cutting control module, etc., the anti-tension damage protection mechanism also has a cutting protection function, which can automatically cut off the low-voltage cable body 001 when the low-voltage cable body 001 is subjected to a large pulling force, thereby preventing the low-voltage cable body 001 from being scrapped to a large extent, thereby reducing losses and reducing maintenance costs.

[0028] The cable cutting distance threshold is less than the alarm distance threshold, and the distance between the distance measuring and pulling rod 204 and the distance sensor 205 is greater than the distance between the bent cable column 202 and the pulling support cylinder 203. Assuming that the distance between the distance measuring and pulling rod 204 and the distance sensor 205 is L1, and the distance between the bent cable column 202 and the pulling support cylinder 203 is L2, when the low-voltage cable body 001 is subjected to a large pulling force, after the bent cable column 202 and the pulling support cylinder 203 are offset, the bent cable column 202 and the distance measuring and pulling rod 204 will not be able to continue to move, so the distance between the distance measuring and pulling rod 204 and the distance sensor 205 cannot be If the cable cutting distance threshold is reduced to (L1-L2) which is smaller than the difference between L1 and L2, then if the cable cutting distance threshold is set to be smaller than the difference between L1 and L2, the cable cutting control module will not control the electric telescopic rod 402 to push the cable cutting blade 403 to cut off the low-voltage cable body 001, and the cutting protection function of the anti-tension damage protection mechanism can be turned off. Therefore, the cutting protection function of the anti-tension damage protection mechanism can be selectively turned on or off according to the situation, and the method of turning on or off the cutting protection function is very simple, which can be achieved by reasonably setting the cable cutting distance threshold, thereby further improving the practicability and reliability of the anti-tension damage protection mechanism.

[0029] See also Figure 7 The cable cutting blade 403 is made of insulating material to prevent leakage. A pair of anti-miscutting baffles 404 are also fixedly installed on the electric telescopic rod 402. The pair of anti-miscutting baffles 404 are respectively located on the left and right sides of the cable cutting blade 403. The distance between the anti-miscutting baffle 404 and the curved cable column 202 is smaller than the distance between the cable cutting blade 403 and the curved cable column 202. The anti-miscutting baffle 404 can protect the low-voltage cable body 001 and prevent the low-voltage cable body 001 from accidentally contacting the cable cutting blade 403 and causing damage to the low-voltage cable body 001.

[0030] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
