Description

Technical Field

[0001] This utility model belongs to the field of power construction equipment technology, and in particular relates to an underground cable winding and laying device. Background Technology

[0002] Underground cables are different from overhead cables and are usually buried underground. During the laying process, underground cables are generally laid out through underground cable channels. Multiple cables will be bundled together at one point during the laying process. The bundled cables laid underground are achieved by installing power distribution line brackets in the underground cable channels and anchoring the power distribution lines to the power distribution line brackets. Existing underground cable winding and laying devices generally consist of several supports fixed to the underground cable channel, with the wound cables laid on the supports. During use, this type of existing underground cable winding and laying device lacks means to deal with fire. When the cable is damaged, leaks electricity, or heat accumulates, it is easy for a fire to start and spread along the cable laying direction. Furthermore, the fire situation of underground cables is difficult to be observed in a timely manner, posing a significant safety hazard. Therefore, it is necessary to make improvements. Utility Model Content

[0003] The purpose of this utility model is to address the aforementioned technical problems by providing an underground cable bundling and laying device to effectively reduce the safety hazards of underground cable laying.

[0004] In view of this, the present invention provides an underground cable coiling and laying device, comprising: The support includes at least one front support and one rear support, with the front support and the rear support distributed at intervals along the cable bundling and laying direction. Cable mounting slots are provided on supports for cable mounting, and the cable mounting slots are of several types and are evenly spaced along the length of the supports. Also includes: A fire-resistant mechanism, which is mounted on a front support and includes a fireproof cloth that can be automatically deployed in the event of a fire; The fireproof cloth of the fireproof mechanism is distributed on the upper and lower sides of the cable bundling and laying direction, and the fireproof cloth on the upper and lower sides automatically unfolds and wraps the bundled and laid cable.

[0005] In this technical solution, a fire-resistant mechanism is installed that automatically triggers the unfolding of fireproof cloth when a fire occurs, forming a wrap around the top and bottom sides of the cable. This process requires no manual intervention, has a short response time, effectively mitigates the development of a fire, and even blocks the spread of flames along the cable. Simultaneously, it isolates the air, assists in fire suppression, and significantly reduces the safety hazards of underground cable fires.

[0006] Furthermore, in the above technical solution, the fire protection mechanism further includes: The roller frame has two roller frames that are symmetrically distributed on the upper and lower sides of the support. The fabric roller includes an upper fabric roller and a lower fabric roller, which are rotatably mounted on two roller frames respectively. An automatic unfolding component is disposed on one side of the fabric roller; The upper and lower fabric rollers are both wound with fireproof cloth, and the automatic unfolding component is used to automatically unfold the fireproof cloth on the upper and lower fabric rollers when a fire occurs.

[0007] In the above technical solution, the automatic deployment component further includes: A movable frame is provided on the side of the cloth roller facing the tail support, and the movable frame can move horizontally along the cable winding and laying direction; The first connecting rod has two rods symmetrically distributed at both ends of the upper cloth roller, and the bottom ends of the two first connecting rods are hinged to the roller shafts at both ends of the upper cloth roller respectively. The second link has two links, which are symmetrically distributed with the two first links along the cable bundling and laying direction. The bottom ends of the two second links are respectively hinged to the top of the two sides of the moving frame. A counterweight bar is disposed at the top of the first connecting rod and the second connecting rod, and the axial direction of the counterweight bar is parallel to the length direction of the support. A locking part is disposed on the upper roller frame, and the locking part includes a locking hook rod; A sensor, positioned above the coiled cable, is used to detect fire. The top ends of the first and second connecting rods are hinged to the counterweight rod. The ends of the fireproof cloth on the upper and lower cloth rollers are fixedly connected to the moving frame. A locking protrusion is provided on one side of the moving frame. The locking hook rod restricts the movement of the moving frame by hooking the locking protrusion and releases the locking protrusion when a fire occurs.

[0008] Furthermore, the above technical solution also includes: The support rod is mounted on the lower roller frame. When the protective cloth is automatically unfolded, the support rod supports the fireproof cloth unfolded at the lower cloth roller upward and brings it closer to the fireproof cloth unfolded at the upper cloth roller.

[0009] Furthermore, the above technical solution also includes: A fixing shell is disposed in a mounting groove. The fixing shell is in the shape of a clamp. A porous buffer layer is provided on the inner wall of the fixing shell. A silicon layer is provided between the porous buffer layer and the inner wall of the fixing shell. The inner wall of the fixing shell is coated with Teflon.

[0010] The beneficial effects of this utility model are: 1. Automatic fire prevention to block the spread of fire: By setting up a fire prevention mechanism and using sensors to monitor the fire situation in the cable area in real time, the fireproof cloth is automatically deployed when a fire occurs: the mobile frame moves rapidly under the weight of the counterweight, causing the upper and lower fireproof cloths to extend from the first support to the last support, forming a wrap around the upper and lower sides of the cable. This process requires no manual intervention, has a short response time, and can effectively mitigate the development of the fire and even block the spread of flames along the cable. At the same time, it isolates the air, assists in fire extinguishing, and significantly reduces the safety hazards of underground cable fires.

[0011] 2. Buffer protection ensures cable safety. A clamp-like fixing shell is installed within the installation trench, followed by a porous buffer layer, a silicon layer, and a Teflon coating. The porous buffer layer absorbs external impact energy, the silicon layer further buffers vibration through elasticity, and the Teflon coating reduces friction between the cable and the fixing shell. This multi-layered protective structure effectively prevents underground cables from colliding and rubbing against the support due to external impacts such as soil settlement and construction vibrations, avoiding wear on the cable insulation or damage to the conductor, extending cable lifespan, and ensuring power supply stability.

[0012] 3. The structure is reliable and highly adaptable. The automatic deployment components adopt a combination of mechanical drive by counterweight and electronic triggering by sensors. It does not rely on the main power supply and is equipped with a backup power supply to ensure normal operation during power outages. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0022] The underground cable winding and laying device in this implementation includes a support frame, a laying groove 3, a fireproof mechanism 4, and a fixing shell 8. The components work together to achieve stable cable winding and laying and automatic fire protection. The specific structure is as follows: support The support structure provides the installation foundation for the entire device and includes at least one front support 1 and one rear support 2. The front support 1 and rear support 2 are spaced apart along the cable bundling direction (i.e., the length of the underground cable tunnel). One end of the support is fixed to the inner wall of the underground cable tunnel using conventional bolts or welding, while the other end extends into the tunnel, forming a cantilever support structure. The support is made of high-strength metal (such as Q235 steel) to ensure it can withstand the weight of multiple cables and external impact loads. The length of the support can be flexibly adjusted according to the width of the underground cable tunnel; the standard design length is 500-800mm to meet the requirements of laying multiple cables side-by-side.

[0023] 3 Erection slots The cable support trough 3 is installed on the extension end of the support frame and is used to support and position the cable. There are several cable support troughs 3, which are evenly distributed along the length of the support frame (i.e., perpendicular to the direction of cable bundling and laying). The distance between two adjacent cable support troughs 3 is 100-150mm, which is suitable for the outer diameter of conventional low-voltage or high-voltage cables (e.g., 50-120mm). The cross-section of the cable support trough 3 is U-shaped, with the opening facing upwards. The depth of the trough is 1 / 2 to 2 / 3 of the outer diameter of the cable, ensuring that the cable can be stably supported in the trough and is not easily dislodged from the opening due to vibration.

[0024] Fixed shell 8 A fixing shell 8 is installed within each mounting slot 3 to further secure and buffer the installed cable. The fixing shell 8 is clamp-shaped, composed of two symmetrical semi-circular shells bolted together. After assembly, it completely wraps around the outer circumference of the cable, and its inner diameter matches the cable's outer diameter, ensuring a tight fit to the cable surface. The inner wall of the fixing shell 8 is sequentially provided with a porous buffer layer 9 and a silicon layer 10, and the inner wall surface is coated with a Teflon coating. The porous buffer layer 9 is made of sponge-like polyurethane material with a thickness of 5-10mm. Its internal porous structure can effectively absorb the energy generated by external impacts (such as soil settlement and vibration) and prevent the impact from being directly transmitted to the cable. The silicon layer 10 is made of high-temperature resistant silicone rubber material with a thickness of 3-5mm. It is attached to the inner side of the porous buffer layer 9. On the one hand, it further buffers vibration through its own elasticity. On the other hand, it can maintain structural stability in high-temperature environments (such as local overheating of the cable) and avoid melting or sticking. The Teflon coating is 0.1-0.2mm thick and is applied to the inner side of the silicon layer 10. Its low coefficient of friction reduces the frictional resistance between the cable and the inner wall of the fixing shell 8, making it easier to lay the cable and pull it out during subsequent maintenance. At the same time, the corrosion resistance of Teflon can prevent oil or moisture on the cable surface from corroding the inner wall of the fixing shell 8.

[0025] Fire protection mechanism 4 Fireproof mechanism 4 is mounted on the first side support 1 and is used to automatically deploy fireproof cloth 5 in the event of a fire to wrap and gather the laid cables, preventing the spread of fire. Fireproof mechanism 4 includes fireproof cloth 5, roller frame 40, cloth roller, automatic deployment component 6, and cloth support rod 7, with the specific structure as follows: (1) Fireproof cloth 5. The fireproof cloth 5 is made of conventional fireproof cloth material (such as glass fiber fireproof cloth 5, basalt fiber fireproof cloth 5), which has the characteristics of high temperature resistance (temperature range ≥500℃), flame retardancy and non-combustibility. The fireproof cloth 5 is distributed on the upper and lower sides of the cable bundling and laying direction, that is, the upper fireproof cloth 5 corresponds to the area above the cable, and the lower fireproof cloth 5 corresponds to the area below the cable; the width of the fireproof cloth 5 is greater than the total width of the cable bundling and laying (that is, the distribution width of all the mounting grooves 3), to ensure that it can completely cover all cables after unfolding. The length of the fireproof cloth 5 is greater than or equal to the distance between the first side bracket 1 and the last side bracket 2, to ensure that it can extend from the first side bracket 1 to the last side bracket 2 after unfolding, so as to achieve full wrapping of the cable between the two brackets.

[0026] Furthermore, several magnets are evenly distributed on both sides of the fireproof cloth 5 (along the sides along the cable winding direction), with a spacing of 150-200mm between adjacent magnets. The magnets are conventional permanent magnets (such as neodymium iron boron magnets) and are fixed to the sides of the fireproof cloth 5 by sewing or bonding. After the fireproof cloth 5 is unfolded on both the top and bottom sides, the magnets on both sides can attract each other, achieving a seal on the sides of the fireproof cloth 5, preventing flames from spreading from the side gaps, and enhancing the stability of the fireproof cloth 5 wrapping.

[0027] (2) Roller frame 40. The roller frame 40 is used to support the cloth roller. There are two roller frames 40, which are symmetrically distributed on the upper and lower sides of the first support 1. Each roller frame 40 consists of two support rods that are spaced apart along the length of the support. The support rods are vertically distributed and made of metal (the same material as the support). One end of the support rod is fixed to the first support 1 by welding, and the other end extends vertically away from the first support 1. The distance between the two support rods is adapted to the length of the cloth roller to ensure that the cloth roller can be stably installed between the two support rods.

[0028] (3) Fabric rollers, which include an upper fabric roller 41 and a lower fabric roller 42, corresponding to the upper and lower fireproof cloth 5 respectively. The upper fabric roller 41 is rotatably mounted on the upper roller frame 40, and the lower fabric roller 42 is rotatably mounted on the lower roller frame 40. The axial direction of the fabric rollers is parallel to the length direction of the support. The fabric rollers include a roller cylinder and a roller shaft. The roller cylinder is a hollow metal cylinder (inner diameter 50-80mm, outer diameter 80-110mm) used to wind the fireproof cloth 5. The roller shaft passes through both ends of the roller cylinder. The two ends of the roller shaft are rotatably connected to the support rod of the roller frame 40 through bearings to ensure that the fabric rollers can rotate flexibly and reduce the frictional resistance when the fireproof cloth 5 is unfolded.

[0029] (4) Automatic unfolding component 6, which is set on the side of the cloth roller facing the tail support 2, and is used to automatically unfold the fireproof cloth 5 on the upper cloth roller 41 and the lower cloth roller 42 when a fire occurs. It includes a moving frame 60, a first connecting rod 61, a second connecting rod 62, a counterweight rod 63, a locking part and a sensor: ① The mobile frame 60 is a conventional square frame, including two side frame poles distributed along the length of the support, and upper and lower frame poles distributed at the top and bottom of the two side frame poles. The side frame poles, upper frame poles, and lower frame poles are all metal poles (such as stainless steel poles) and are assembled into a square frame structure by welding or bolting. The inner contour dimension of the square frame is larger than the total dimension of the cable bundle laying to ensure that it will not interfere with the cable when moving.

[0030] The unfolded end of the fireproof cloth 5 on the upper cloth roller 41 is connected to the upper frame rod of the moving frame 60 through a conventional hook structure (such as a metal hook) or a buckle structure (such as a plastic buckle). The unfolded end of the fireproof cloth 5 on the lower cloth roller 42 is connected to the lower frame rod of the moving frame 60 through a conventional hook structure (such as a metal hook) or a buckle structure (such as a plastic buckle). The spacing between the hook structure and the buckle structure is adapted to the width of the fireproof cloth 5 to ensure that the unfolded end of the fireproof cloth 5 can be evenly stressed and avoid local tearing.

[0031] Furthermore, a guide support structure is provided on one side of the mobile frame 60 to ensure that the mobile frame 60 moves smoothly along the cable winding and laying direction. The guide support structure includes a guide support rod, the two ends of which are fixed to the first side bracket 1 and the last side bracket 2 by bolts, respectively, and its length direction is parallel to the cable winding and laying direction; the corresponding side frame rod of the mobile frame 60 has a guide hole that cooperates with the guide support rod. The inner diameter of the guide hole is slightly larger than the outer diameter of the guide support rod (gap 0.5-1mm). The guide support rod passes through the guide hole to form a movable fit, which restricts the swaying of the mobile frame 60 and ensures that the fireproof cloth 5 is unfolded in a straight direction.

[0032] ② The first connecting rod 61 and the second connecting rod 62 are provided. There are two first connecting rods 61, which are symmetrically distributed at both ends of the upper cloth roller 41 (along the length of the support). The bottom ends of the two first connecting rods 61 are respectively hinged to the roller shafts at both ends of the upper cloth roller 41. There are two second connecting rods 62, which are symmetrically distributed with the two first connecting rods 61 along the cable winding and laying direction. The bottom ends of the two second connecting rods 62 are respectively hinged to the top of the side frame rods on both sides of the movable frame 60.

[0033] Both the first link 61 and the second link 62 are metal rods (300-500mm in length). Their top ends are hinged to the counterweight rod 63, and conventional torsion springs (or springs) are arranged at the hinge points. The two ends of the torsion springs are fixedly connected to the first link 61 and the second link 62, respectively. When the automatic deployable part 6 is in the retracted state (normal non-fire state), the first link 61 and the second link 62 are close to each other, forming a triangular shape, and the torsion springs are in a compressed or torsional storage state. When the automatic deployable part 6 is in the deployed state (when a fire occurs), the torsion springs release their elastic force, pushing the first link 61 and the second link 62 to separate from each other and gradually become horizontal, forming a straight line, thereby driving the moving frame 60 to move towards the rear support 2.

[0034] ③ Counterweight rod 63: The counterweight rod 63 is located at the top of the first connecting rod 61 and the second connecting rod 62. Its axis is parallel to the length direction of the support. It is made of metal (such as cast iron), and its length is adapted to the distance between the two first connecting rods 61 in the length direction of the support (i.e., consistent with the length of the cloth roller). Its weight is 5-10 kg. The gravity of the counterweight rod 63, together with the elastic force of the torsion spring, drives the first connecting rod 61 and the second connecting rod 62 to unfold after the automatic unfolding component 6 is unlocked, ensuring that the moving frame 60 can move quickly and realize the rapid unfolding of the fireproof cloth 5.

[0035] ④ Locking part: The locking part is installed on the upper roller frame 40 and is used to restrict the movement of the movable frame 60 under normal conditions and release the movable frame 60 in the event of a fire. It includes a locking hook 64, a drive motor and a locking protrusion 65. The locking protrusion 65 is a conventional metal protrusion, which is fixed to the side frame rod of the movable frame 60 near the first side support 1 by welding. The height of the protrusion is 20-30mm and the width is 30-40mm. The drive motor is a conventional stepper motor (such as 57HS22), which is fixedly mounted on the side wall of the support rod of the upper roller frame 40 by bolts, and the output shaft of the drive motor faces the locking protrusion 65; One end of the locking hook 64 is fixedly connected to the output shaft of the drive motor via a coupling, and the other end is in the shape of a conventional hook (the hook opening faces the locking protrusion 65), with the size of the hook opening matching the locking protrusion 65. Under normal conditions, the drive motor drives the locking hook 64 to rotate, causing the hook opening to engage with the locking protrusion 65 and restricting the movement of the movable frame 60; in the event of a fire, the drive motor drives the locking hook 64 to rotate in the opposite direction, causing the hook opening to disengage from the locking protrusion 65 and releasing the movable frame 60.

[0036] ⑤ Sensor: The sensor is positioned above the cable coil 11 to detect fire. It employs a conventional temperature sensor (such as a PT100 temperature sensor) or a smoke sensor (such as an MQ-2 smoke sensor). The sensor is fixed to the top of the first-side bracket 1 by a bracket, with its detection end facing the cable area. The sensor and the drive motor of the locking unit are electrically connected via a conventional control line and are equipped with an independent backup power supply (such as a lithium battery) to ensure normal operation when the main power is interrupted. When the sensor detects that the temperature in the cable area exceeds a preset threshold (such as 80°C) or detects smoke, it sends a signal to the drive motor, triggering the locking unit to unlock.

[0037] (5) Support rod 7: The support rod 7 is installed on the lower roller frame 40. It is used to support the fireproof cloth 5 that is unfolded at the lower cloth roller 42 when the fireproof cloth 5 is automatically unfolded, so that it is close to the fireproof cloth 5 that is unfolded at the upper cloth roller 41, so as to ensure that the upper and lower fireproof cloths 5 can be accurately attached and attracted by magnets. The length direction of the support rod 7 is parallel to the length direction of the bracket, and the length is greater than or equal to the width of the fireproof cloth 5 (to ensure that the fireproof cloth 5 can be fully supported). The material is a metal rod (such as an aluminum alloy rod) with a diameter of 15-20mm.

[0038] The drive mechanism of the support rod 7 is the same as that of the locking hook rod 64: a drive motor (the same model as the drive motor of the locking part) is fixedly installed on the side wall of the support rod of the lower roller frame 40, and a drive arm (metal rod, 100-150mm in length) is fixedly installed on the output shaft of the drive motor. One end of the support rod 7 is connected to the free end of the drive arm by bolts. Under normal conditions, the support rod 7 is located below the lower fireproof cloth 5 and does not contact the fireproof cloth 5. When the fireproof cloth 5 is unfolded, the sensor synchronously sends a signal to the drive motor, which drives the drive arm to rotate upward, thereby moving the support rod 7 to a preset height (i.e., the middle position of the lower fireproof cloth 5), lifting the lower fireproof cloth 5 upward, so that the magnet of the lower fireproof cloth 5 is accurately aligned with the magnet of the upper fireproof cloth 5 and attracts it.

[0039] Work process Normal state: The drive motor of the locking part drives the locking hook 64 to hook the locking protrusion 65 of the moving frame 60, the moving frame 60 is stationary, and the fireproof cloth 5 is wound on the cloth roller; the cloth support rod 7 is located below the lower fireproof cloth 5 and does not contact the fireproof cloth 5; the fixing shell 8 wraps the cable, the porous buffer layer 9 and the silicon layer 10 absorb external impact, and the Teflon coating reduces cable friction. Fire Trigger: Suppose a cable short-circuits due to insulation damage, and the local temperature rises to 90°C. The PT100 temperature sensor detects that the temperature exceeds the preset threshold (80°C) and immediately sends a signal to the drive motor of the locking part and the support rod 7. Unlocking and moving: After receiving the signal, the drive motor of the locking part drives the locking hook rod 64 to rotate 30° in the opposite direction, and the hook mouth disengages from the locking protrusion 65; under the combined action of the counterweight rod 63 (8kg) and the elastic force of the torsion spring (TC080), the moving frame 60 moves along the guide support rod towards the tail support 2 at a speed of about 0.5m / s. Fireproof cloth 5 unfolds: During the movement of the moving frame 60, the fireproof cloth 5 on the upper cloth roller 41 and the lower cloth roller 42 is simultaneously pulled to unfold. The upper cloth roller 41 and the lower cloth roller 42 rotate as the fireproof cloth 5 is pulled, and the fireproof cloth 5 extends from the first side support 1 to the last side support 2. Support and sealing: After receiving the signal, the drive motor of the support rod 7 drives the drive arm to rotate upward by 60°, and the support rod 7 moves up to the middle position of the lower fireproof cloth 5, supporting the lower fireproof cloth 5 upward; when the moving frame 60 moves to the tail support 2, the fireproof cloth 5 is fully unfolded (length 5m), and the neodymium iron boron magnets on both sides of the upper and lower fireproof cloth 5 attract each other to form a sealed package; Fire suppression: The sealed fireproof cloth 5 isolates the cable from air, and the flames gradually extinguish due to lack of oxygen, while preventing the fire from spreading to other areas; after discovering the fire, the staff can remove the fireproof cloth 5 through the cable channel inspection port to maintain the faulty cable.
