Description

Technical Field

[0001] This invention relates to the field of composite flexible cable technology, specifically to a composite flexible cable and its manufacturing method. Background Technology

[0002] Composite flexible cable is a type of cable made of flexible and composite materials. This type of composite flexible cable performs well in various environments and applications. It is generally used in industrial automation, robotics, and medical device fields. It is typically buried in the ground or used as an overhead cable.

[0003] Existing composite flexible cables buried in the ground can ensure stable power and signal transmission and have a long service life in various environments. However, they cannot achieve remote monitoring of the cable's usage status. After prolonged use, the cable's outer sheath may corrode and crack due to certain factors in the soil. If this is not detected and addressed in time, and users of this section of cable are not notified, water may enter the cable, potentially affecting signal and current transmission, or even causing a short circuit. This would affect the users of that section of cable and reduce the efficiency of the composite flexible cable.

[0004] Therefore, a new type of composite flexible cable and its production method are needed to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a composite flexible cable and its manufacturing method to solve the problems mentioned in the background art, namely, that existing composite flexible cables buried in the ground cannot achieve remote monitoring of cable usage status, and that after long-term use, the cable sheath may corrode and crack due to certain factors in the soil. If this is not detected and dealt with in time and the users of this section of cable are not notified, water may enter the cable, affecting signal and current transmission, and even causing short circuits, thereby affecting the users of that section of cable and reducing the efficiency of the composite flexible cable.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a composite flexible cable, comprising a cable mechanism, wherein a monitoring mechanism is provided on the cable mechanism;

[0007] The monitoring mechanism includes multiple core wire holes and a mounting box. Each core wire hole contains a core wire body. A rectangular plate is installed at the inlet of the mounting box. A placement slot is formed on one side of the inner wall of the mounting box, and a battery is placed inside the placement slot. A T-shaped hole is formed at the top of the inner wall of the mounting box, and a junction box is installed inside the T-shaped hole. A leakage current protector is installed on the inner wall of the mounting box. A vent is formed at the bottom of the inner wall of the mounting box. A light is installed on the inner wall of the mounting box. A dustproof net is installed at the bottom of the inner wall of the mounting box. A controller and a wireless transmitter are installed on the inner wall of the mounting box. A protective shell is installed on the inner wall of the mounting box. A mounting hole is formed on the inner wall of the protective shell. A photosensitive sensor is installed on the outer wall of the protective shell. A cable tray is formed on the surface of the protective shell.

[0008] Preferably, the dustproof mesh is located at the air inlet of the ventilation hole, the battery is electrically connected to the controller, the controller is electrically connected to the wireless transmitter, the controller is electrically connected to the leakage current protector, the lighting lamp is electrically connected to the controller, and the photosensitive sensor is electrically connected to the controller, so that the light intensity inside the protective shell can be monitored at all times with the cooperation of the controller and the photosensitive sensor.

[0009] Preferably, the cable mechanism includes an outer protective sleeve, the mounting box is installed on the outer protective sleeve by screws, a plurality of connecting rings are fixedly distributed at equal intervals on the outer wall of the outer protective sleeve, a fireproof sleeve is provided inside the outer protective sleeve, and an isolation sleeve is provided inside the fireproof sleeve, so that the performance of the composite flexible cable can be improved under the action of the isolation sleeve.

[0010] Preferably, a plurality of core wire holes are equidistantly distributed on one side of the isolation sleeve, and a plurality of placement holes are equidistantly distributed on one side of the isolation sleeve. The plurality of placement holes and the plurality of core wire holes are arranged in an alternating manner. Each placement hole is provided with a first silicone strip inside, which can improve the flame retardancy of the composite flexible cable under the action of the first silicone strip.

[0011] Preferably, the isolation sleeve has a first inner protective sleeve inside, and the first inner protective sleeve has a flexible corrugated shell inside. The flexible corrugated shell has arc-shaped strips fixed at the included angles inside, and multiple connecting strips are fixed at equal intervals on the inner wall of the flexible corrugated shell. This allows the vibration resistance of the copper core inside the composite flexible cable to be improved through the cooperation of the flexible corrugated shell, connecting strips and arc-shaped strips.

[0012] Preferably, a second inner protective sleeve is provided between the outer walls of the plurality of arc-shaped strips, and one end of each connecting strip is fixed to the outer wall of the second inner protective sleeve. The interior of the second inner protective sleeve is provided with a copper strip shielding layer, which can improve the stability of the composite flexible cable during use under the action of the copper strip shielding layer.

[0013] Preferably, the copper strip shielding layer has a filling layer inside, and six arc-shaped holes are equally distributed on one side of the filling layer. Each of the three arc-shaped holes has multiple tensile ropes inside, and each arc-shaped hole has a second silicone strip inside. This allows the flame retardancy of the composite flexible cable to be further improved under the action of the second silicone strip.

[0014] Preferably, a plurality of annular holes are equidistantly distributed on one side of the filling layer, and three slots are equidistantly distributed on the inner wall of each annular hole. An insulating sleeve is provided inside each annular hole, and an oxygen barrier layer is provided inside each insulating sleeve.

[0015] Preferably, each of the oxygen-barrier layers has a copper core inside, and three locking blocks are fixedly distributed at equal intervals on the outer wall of each insulating sleeve. Each locking block is movably fitted into the inside of each slot. A cylindrical hole is opened on one side of the filling layer, and an optical fiber is installed inside the cylindrical hole to facilitate communication operations by the optical fiber user. At the same time, the cooperation of the locking blocks and slots can prevent the insulating sleeve from rotating inside the filling layer.

[0016] A method for producing a composite flexible cable includes the following steps:

[0017] S1. When it is necessary to make a composite flexible cable, the copper core, oxygen barrier layer and insulation sleeve can be combined together to make a copper wire by first using the wire making equipment. Then, the clamp can be made on the insulation sleeve by using the cable making equipment. Finally, the copper tape shielding layer, filling layer, optical fiber and multiple copper wires can be combined together by using the cable making equipment.

[0018] S2. Then, with the help of cable manufacturing equipment, the second inner protective sleeve, multiple connecting strips, flexible corrugated shell, arc strip, first inner protective sleeve, isolation sleeve, fireproof sleeve and outer protective sleeve can be made sequentially on the outer wall of the copper tape shielding layer. Then, with the cooperation of arc hole and placement hole, the cable tensile rope, second silicone strip and first silicone strip can be installed, thereby realizing the production of composite flexible cable.

[0019] S3. When the core wire comes into contact with water, the circuit consisting of the core wire, the leakage current protector, the junction box and the controller will short-circuit. At this time, the leakage current protector can break the circuit.

[0020] S4. Then, with the cooperation of the controller, protective shell, photosensitive sensor and battery, the light intensity inside the protective shell can be detected. Then, with the cooperation of the controller, battery and wireless transmitter, it is possible to realize whether the monitoring equipment inside the monitoring room is transmitting information and reminding the monitoring personnel to promptly send maintenance personnel to check the composite flexible cable with problems.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. This invention, by setting up a monitoring mechanism, can remotely monitor the usage status of the composite flexible cable at all times. At the same time, it can promptly remind the monitoring personnel when a problem occurs, which effectively ensures the normal use of the cable by the user and ensures the stable transmission of signals and current in the later stage of the cable, thereby improving the usage efficiency of the composite flexible cable. When the core wire body comes into contact with water, the circuit composed of the core wire body, leakage current protection device, junction box and controller will short-circuit. At this time, under the action of leakage current protection device, the circuit above can be disconnected.

[0023] 2. This invention, by utilizing a controller, protective shell, photosensitive sensor, and battery, can detect the light intensity inside the protective shell. Then, by using the controller, battery, and wireless transmitter, it can send information to the monitoring equipment inside the monitoring room to remind them whether to perform the operation, thus facilitating the monitoring personnel to promptly dispatch maintenance personnel to check the composite flexible cable with problems.

[0024] 3. This invention, through the setting of a cable mechanism, enables power, signal, and communication operations, while also improving the cable's service life. When manufacturing composite flexible cables, the copper core, oxygen barrier layer, and insulating sleeve are first combined using wire fabrication equipment to form copper wire. Then, using cable fabrication equipment, a clip is made on the insulating sleeve. Next, using cable fabrication equipment, the copper strip shielding layer, filling layer, optical fiber, and multiple copper wires are combined. Then, using cable fabrication equipment again, a second inner protective sleeve, multiple connecting strips, a flexible corrugated shell, an arc-shaped strip, a first inner protective sleeve, an isolation sleeve, a fireproof sleeve, and an outer protective sleeve are sequentially formed on the outer wall of the copper strip shielding layer. Finally, with the cooperation of the arc-shaped hole and the placement hole, the cable's tensile rope, the second silicone strip, and the first silicone strip are installed, thereby realizing the production of composite flexible cables.

[0039] according to Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the cable mechanism 1 includes an outer protective sleeve 101. The mounting box 203 is installed on the outer protective sleeve 101 by screws. Multiple connecting rings 102 are fixed at equal intervals on the outer wall of the outer protective sleeve 101. A fireproof sleeve 103 is provided inside the outer protective sleeve 101. An isolation sleeve 104 is provided inside the fireproof sleeve 103. Under the action of the isolation sleeve 104, the performance of the composite flexible cable can be improved.

[0040] according to Figure 1 and Figure 6As shown, multiple core wire holes 201 are equidistantly distributed on one side of the isolation sleeve 104, and multiple placement holes 105 are equidistantly distributed on one side of the isolation sleeve 104. The multiple placement holes 105 and the multiple core wire holes 201 are arranged in an alternating manner. Each placement hole 105 is provided with a first silicone strip 106 inside, which can improve the flame retardancy of the composite flexible cable under the action of the first silicone strip 106.

[0041] according to Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, the isolation sleeve 104 has a first inner protective sleeve 109 inside, and a flexible corrugated shell 110 inside the first inner protective sleeve 109. Arc-shaped strips 111 are fixed at the included angles inside the flexible corrugated shell 110, and multiple connecting strips 112 are fixed at equal intervals on the inner wall of the flexible corrugated shell 110. This facilitates the improvement of the shock resistance of the copper core 108 inside the composite flexible cable by cooperating with the flexible corrugated shell 110, the connecting strips 112 and the arc-shaped strips 111.

[0042] according to Figure 6 , Figure 7 and Figure 8 As shown, a second inner protective sleeve 113 is provided between the outer walls of multiple arc-shaped strips 111. One end of each connecting strip 112 is fixed to the outer wall of the second inner protective sleeve 113. A copper tape shielding layer 114 is provided inside the second inner protective sleeve 113, which can improve the stability of the composite flexible cable during use under the action of the copper tape shielding layer 114.

[0043] according to Figure 1 , Figure 7 and Figure 8 As shown, the copper strip shielding layer 114 has a filling layer 115 inside. Six arc-shaped holes 116 are evenly distributed on one side of the filling layer 115. Multiple tensile ropes 117 are provided inside three of the arc-shaped holes 116. A second silicone strip 118 is provided inside each arc-shaped hole 116. Under the action of the second silicone strip 118, the flame retardant ability of the composite flexible cable can be further improved.

[0044] according to Figure 1 , Figure 7 and Figure 8 As shown, multiple annular holes 119 are equidistantly distributed on one side of the filling layer 115. Three slots 120 are equidistantly distributed on the inner wall of each annular hole 119. An insulating sleeve 122 is provided inside each annular hole 119. An oxygen barrier layer 107 is provided inside each insulating sleeve 122. Under the action of the oxygen barrier layer 107, the corrosion resistance of the copper core 108 can be improved, that is, the service life of the copper core 108 can be improved.

[0045] according to Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, each oxygen barrier layer 107 has a copper core 108 inside, and three locking blocks 121 are fixedly distributed at equal intervals on the outer wall of each insulating sleeve 122. Each locking block 121 is movably sleeved inside each slot 120. A cylindrical hole 123 is opened on one side of the filling layer 115. An optical fiber 124 is installed inside the cylindrical hole 123, which facilitates communication operations for the user of the optical fiber 124. At the same time, with the cooperation of the locking block 121 and the slot 120, the insulating sleeve 122 can be prevented from rotating inside the filling layer 115.

[0046] In this invention, when it is necessary to produce a composite flexible cable, the copper core 108, oxygen barrier layer 107, and insulating sleeve 122 are first combined using wire fabrication equipment to form copper wire. Then, multiple clips 121 are fabricated on the insulating sleeve 122 of each copper wire. Next, the copper tape shielding layer 114, filling layer 115, optical fiber 124, and multiple copper wires are combined using cable fabrication equipment. Then, a second inner protective sleeve 113, multiple connecting strips 112, a flexible corrugated shell 110, an arc-shaped strip 111, a first inner protective sleeve 109, an isolation sleeve 104, a fireproof sleeve 103, and an outer protective sleeve 101 are sequentially fabricated on the outer wall of the copper tape shielding layer 114 using cable fabrication equipment. Finally, the three arc-shaped holes 116 are then... Do not insert the tensile rope 117. Then, insert the second silicone strip 118 inside each arc-shaped hole 116. Finally, insert the first silicone strip 106 inside each placement hole 105. Simultaneously, insert the core wire body 202 inside each core wire hole 201. When the composite flexible cable is manufactured, directly fabricate multiple connecting rings 102 on the outer wall of the outer protective sleeve 101 of the cable. When the composite flexible cable is needed, cut the cable to the required length. Then, install cable connectors on all copper cores 108 on the cable. Next, wrap both ends of each core wire body 202 with melted insulating glue. Then, connect one end of each core wire body 202 together in pairs, and then use insulating tape. After protecting the core wires, connect the other ends of the two connected core wires 202 to the junction box 208. Finally, connect the junction box 208, lighting 211, controller 213, and leakage current protector 209 in series. Connect the controller 213 to the battery 206. When everything is ready, use the wireless transmitter 214 to wirelessly connect the controller 213 to the monitoring equipment in the monitoring room. Then, bury the composite flexible cable in the ground, connecting both ends to the required devices. Power and signal transmission can then begin. Next, install the mounting box 203 on one end of the outer protective sleeve 101 of the cable, then remove the rectangular plate 204, and then open the controller. 213. After setting the light intensity threshold and operating procedure, finally install the rectangular plate 204 back to its initial position. This allows for continuous monitoring of the cable's condition. When the cable is first installed, the leakage current device 209 is in the open position. With the cooperation of the leakage current device 209, the core wire body 202, the junction box 208, and the controller 213, and powered by the battery 206, the lighting lamp 211 is illuminated. Simultaneously, with the controller 213 open, the photosensitive sensor 217 continuously monitors the light intensity within the space formed by the mounting box 208 and the protective shell 215. The light intensity data detected by the photosensitive sensor 217 is then transmitted to the controller 213 as an electrical signal.Next, the controller 213 compares the received light intensity data with the light intensity threshold preset by the controller 213. However, under normal cable conditions, the light intensity data received by the controller 213 will be higher than the preset light intensity threshold. In this case, the controller 213 will not send an alarm to the monitoring equipment in the monitoring room through the cooperation of the wireless transmitter 214 and the battery 206. When the cable has been used for a long time and has corroded and cracked due to certain factors in the soil, if it rains, water will enter the soil. This water will enter the interior of the composite flexible cable through the opening. When the water enters the core wire body 202 of the composite flexible cable, the core wire body 202 will short-circuit due to the water. When a short circuit occurs in the circuit composed of the core wire body 202, the leakage current protector 209, the junction box 203, and the controller 213, the leakage current protector 209 will activate to protect the circuit. When the leakage current protector 209 trips and shuts down, the lighting 211 will turn off. At this time, the photosensitive sensor 217 will transmit the detected light intensity data to the controller 213. The light intensity data received by the controller 213 will be lower than or equal to the preset light intensity threshold. When the controller 213 detects that the received light intensity data is lower than or equal to the preset threshold, it will send an alarm to the monitoring equipment in the monitoring room via the wireless transmitter 214 and battery 206. This alerts the monitoring personnel to send someone to check the cable. If cracks are found, maintenance personnel can promptly notify the user of that section of cable, informing them of the appropriate time for repairs. This effectively ensures the cable's usability for the user and guarantees stable signal and current transmission in the future, thereby improving the efficiency of the composite flexible cable.

[0047] The components of the residual current device 209 include: a zero-sequence current transformer, a tripping mechanism, a residual current trip unit, a main switch, and a test button.

[0048] The residual current device 209 mainly consists of three parts: a detection element, an intermediate amplification stage, and an operating actuator. The detection element is composed of a zero-sequence transformer, which detects the leakage current and sends a signal. The amplification stage amplifies the weak leakage signal for different devices (the amplification part can use mechanical or electronic devices). After receiving the signal, the actuator switches the main switch from the closed position to the open position, thereby cutting off the power supply. The power supply is the tripping element between the protected circuit and the power grid.

[0049] Among them, the oxygen barrier layer 107 is an anti-oxidant coating, the copper strip shielding layer 114, the optical fiber 124, the battery 206, the junction box 208, the leakage current protector 209, the lighting lamp 211, the controller 213 (PLC controller), the wireless transmitter 214 and the photosensitive sensor 217 are all existing technologies and will not be explained in detail here.

[0050] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

Then, the copper tape shielding layer (114), filling layer (115), optical fiber (124) and multiple copper wires can be combined together by using the cable making equipment. S2. Then, with the help of cable manufacturing equipment, the second inner protective sleeve (113), multiple connecting strips (112), flexible corrugated shell (110), arc strip (111), first inner protective sleeve (109), isolation sleeve (104), fireproof sleeve (103) and outer protective sleeve (101) can be made sequentially on the outer wall of the copper strip shielding layer (114). Then, with the cooperation of the arc hole (116) and the placement hole (105), the anti-tensile rope (117), the second silicone strip (118) and the first silicone strip (106) of the cable can be installed, thereby realizing the production of composite flexible cable. S3. When the core wire body (202) comes into contact with water, the circuit consisting of the core wire body (202), the leakage current protector (209), the junction box (208) and the controller (213) will be short-circuited. At this time, the circuit can be disconnected under the action of the leakage current protector (209). S4. Then, with the cooperation of the controller (213), protective shell (215), photosensitive sensor (217) and battery (206), the light intensity inside the protective shell (215) can be detected. Then, with the cooperation of the controller (213), battery (206) and wireless transmitter (214), the information transmission reminder operation of the monitoring equipment inside the monitoring room can be realized, so as to facilitate the monitoring personnel to send maintenance personnel to check the composite flexible cable with problems in a timely manner.
