Description

Technical Field

[0001] The present invention relates to the field of power cable laying, and in particular to a power cable laying mechanism and a distributed power cable laying device. Background Art

[0002] In substation maintenance work, the laying of power cables is a vital routine operation, which is directly related to the safety and stability of the power system. However, the traditional cable laying method has many shortcomings and needs to be improved. The existing cable laying operation usually relies on the cable laying machine set at the head end as the power source, and a number of pulleys are placed in the cable channel to assist the dragging and laying of the cable. Although this method has improved the operation efficiency to a certain extent, there are still many problems.

[0003] First, the cable is very easy to fall off the pulley block during the dragging process, which makes it impossible for the cable to pass smoothly. This not only increases the complexity of the operation, but also may cause damage to the cable, especially when the cable rubs against other components in the channel, which can easily lead to damage to the cable insulation layer, thereby affecting the electrical performance and safety of the cable. In addition, damage to the cable insulation may also cause safety hazards such as electric shock, which brings great risks to the operators.

[0004] Secondly, the manual dragging method is relatively inefficient. Traditional cable laying requires a lot of manpower support, and usually requires a team of more than ten people to collaborate to complete the cable laying work. This not only increases labor costs, but also leads to slow work progress and cannot meet the needs of modern power systems for fast and efficient construction. In some complex or dangerous environments, such as underground pipe corridors or high-altitude operations, the safety risks of manual operations are significantly increased. Summary of the invention

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] refer to Figure 1 As shown, the present invention provides a distributed power cable laying device, including a cable drum fixing device 1, a fixed pulley block 2, and a power cable laying mechanism 3, wherein Figure 1In the figure, a is a cable trench, and b is a power cable. The devices are distributed in the cable trench. The cable is manually passed through a fixed pulley group and then pulled to the power cable laying mechanism. The photosensitive element of the power cable laying mechanism senses the passage of the cable and sends an action signal. After the power cable laying mechanism tightens the transmission pulley to a suitable position through an electric push rod, the transmission pulley starts to move, and the cable passes through the power cable laying mechanism and continues to be transmitted forward. When the cable is transmitted to the next power cable laying mechanism, the power cable laying mechanism recognizes the cable and tightens the transmission pulley. The second power cable laying mechanism is connected to the first power cable laying mechanism. The power cable laying mechanism cooperates to send the cable to the bend of the channel. A guide pulley 7 is provided at the bend. Manual traction passes through the guide pulley 7 to realize the cable change. The first power cable laying mechanism and the second power cable laying mechanism keep running. The cable is sent to the subsequent device and the above operation is repeated until the cable is sent to the designated position. During the entire operation process, the distributed power cable laying device is designed to ensure safety, liberate manpower and improve efficiency. The work that originally required more than ten people to drag now only requires two to three people to pull the cable head, and one person can monitor the operating status of the device at the terminal.

[0042] Specifically, the cable drum fixing device 1 includes a cable drum 11 and a bracket 12. The cable drum 11 is vertically mounted and fixed on the bracket 12. When in use, a rotating shaft is provided on the bracket 12. In this embodiment, the cable drum fixing device 1 is not provided with auxiliary power. When releasing the cable, the rotating direction of the cable drum 11 is as follows: Figure 1 As shown by the arrow in FIG. , the cable is passed obliquely downward and then introduced between the fixed pulleys, and then introduced into the subsequent device.

[0043] The fixed pulley block 2 is a double pulley structure, and the double pulley structure is distributed up and down in the vertical direction. When in use, the cable is pulled out from the cable drum 11 and first passes through the fixed pulley block 2 to avoid abnormal friction with the ground and other components. In addition, the direction of the cable is changed from inclined downward to moving in the horizontal direction, which is convenient for entering the subsequent distributed cable laying device.

[0044] refer to Figure 4 and 5 As shown, the fixed pulley block 2 includes a pulley 21, a fixed bracket 22, a support seat 23 and a detachable fixed base 24; the fixed bracket 22 is installed on the upper part of the support seat 23, the pulley 21 is installed on the fixed bracket 22, and the support seat 23 is installed on the upper part of the detachable fixed base 24; in this embodiment, the surface of the pulley 21 has an inward curvature, which can facilitate the fixation of the cable, and there is a groove at the bottom of the support seat 23 to facilitate the connection with the detachable fixed base 24.

[0045] refer to Figure 6 and 7As shown, the detachable fixed base 24 is a stepped structure with two layers, the lower part of the detachable fixed base 24 is a semi-elliptical structure, the upper part of the detachable fixed base 24 is a rectangular structure, and a fixed slide groove 241 is provided in the rectangular structure. One end of the fixed slide groove 241 is completely closed, and the other end of the fixed slide groove 241 has an opening, and the open end has a hole for installing the tail plug 243; fixing holes 242 are provided on both sides of the fixed slide groove 241; the detachable fixed base 24 can be applied to a variety of application scenarios.

[0046] refer to Figure 8-10 As shown, in order to fix the detachable fixing base 24 , a fixing mechanism 25 is provided at the lower part of the detachable fixing base 24 .

[0047] Please continue to refer to Figure 8 As shown, when the fixed contact surface is a smooth surface, the fixing mechanism 25 is a suction cup 251; when the suction cup 251 is used, the suction cup 251 is first fixed on the smooth surface, and then the detachable fixing base 24 is passed through the upper end of the suction cup 251 and the screws are tightened, and then the fixed pulley block 2 is fixed.

[0048] Please continue to refer to Fig. 9 As shown, when the fixed contact surface is a cement hard surface, the fixing mechanism 25 is a punching bolt 252, and the punching bolt 252 includes a punching screw 2521 and an expansion bolt 2522; when in use, first drill a hole on the cement hard surface with an electric drill, put the expansion bolt 2522, align the detachable fixed base 24, and then put the gasket 2523 at the bottom of the detachable fixed base 24, and the punching screw 2521 passes through the fixing hole 242 to fix the fixed pulley block 2.

[0049] Please continue to refer to Fig.10 As shown, when the fixed contact surface is a soft surface such as soil, the fixing mechanism 25 is a screw nail 253. When the screw nail 253 is in use, the screw nail 253 is placed first. The shape of the base of the screw nail 253 matches the fixed slide groove 241. The base of the screw nail 253 is pushed in from the open end of the fixed slide groove 241, and then the tail plug 243 is inserted from the opening of the fixed slide groove 241. The shape of the tail plug 243 is similar to a long screw, one end of which is a fixed part and the other end has a thread. After the tail plug 243 is inserted, the nut is inserted and tightened to complete the fixation of the pulley block.

[0050] It should be noted that, unless otherwise specified, other devices are also fixed by the above-mentioned fixing mechanism 25 , and thus will not be described again.

[0051] refer to Figure 11-15As shown, the power cable laying mechanism 3 includes a cable transmission mechanism 31, a control system 32 and a collection unit; the cable transmission mechanism 31 is installed inside the power cable laying mechanism 3 through an upper partition 4, and the control system 32 is installed at the lower part of the power cable laying mechanism 3 through a lower partition 5; the collection unit includes a pressure sensor 33 and a photosensitive sensor 34; refer to Figure 11-13 As shown, the cable transmission mechanism 31 includes a motor 311, a first fixed row 313, a second fixed row 314, a transmission pulley 315, a fixed bearing 316, and an electric push rod 312; specifically, the first fixed row 313 and the second fixed row 314 are installed on the upper partition 4, and a slide groove 41 is provided on the upper partition 4. The upper part of the motor 311 is installed on the second fixed row 314. To facilitate the extension and retraction of the electric push rod 312, the lower part of the motor 311 is fixed to the first fixed row 313; the electric push rod 312 is installed on the first fixed row 313 and drives the motor 311 to move in the slide groove 41; the transmission pulley 315 is installed on the second fixed row 314 through a fixed bearing 316 and is connected to the motor 311; wherein, the motor 311 is coaxial with the transmission pulley 315.

[0052] refer to Fig.14 and 15 As shown, the control system 32 includes a power supply module 321, a main control board 322 and a wireless module 323; the main control board 322 is connected to the power supply module 321; the main control board 322 is connected to the motor 311 through a motor drive board 324; the power supply module 321 is connected to the motor 311 through a wire; the wireless module 323 is connected to the main control board 322; the power supply module 321 includes a battery 325, a power board 326 and a step-down module 327; the battery 325 is connected to the step-down module 327 through the power board 326; refer to Fig.16As shown, when the motor is under constant torque control, the battery 325 is connected to a power board 326, and the power board 326 divides the power into two paths, one of which is transmitted to the main control board 322 through the step-down module 327. Through the above steps, the constant torque control of the DC motor can be realized, so that the motor can still output a stable torque when facing a changing load. The main control board 322 output line is divided into two paths, one of which is connected to the wireless module 323, and the other is connected to the motor drive board 324; specifically, when the motor is under constant torque control, PID control is used to realize constant torque and set a target torque T_set. Read the armature current I obtained by the current sensor. According to the motor specifications, the actual torque T_actual = K_t * I is calculated, where K_t is the torque constant of the motor. The PID controller calculates the error E = T_set - T_actual. According to the PID algorithm, the control output U = Kp*E + Ki*∫E*dt + Kd*dE / dt is calculated, where Kp, Ki and Kd are proportional, integral and differential gains respectively. U is used to adjust the driving signal of the motor. In this device, the PWM duty cycle is adjusted to adjust the motor current and thus the torque. Through the above steps, the constant torque control of the DC motor can be achieved, so that the motor can still output a stable torque when facing a changing load.

[0053] In the above embodiment, there are three communication schemes for the wireless transmission unit of the wireless module 323. Scheme 1 uses Bluetooth connection, scheme 2 uses WiFi connection, and scheme 3 uses Zigbee connection. Combined with the on-site design requirements: the amount of wireless transmission information is small, and the transmission rate requirement is not high; since the device is battery-powered, the power consumption of the wireless module 323 should not be too large; at the same time, the environment in the substation is complex, and the devices may be distributed between walls. In addition, there are many signal interference factors generated by other communication devices in the substation, and high anti-interference ability and stability requirements are required for the wireless connection. The best choice for this scheme is to use Zigbee wireless communication.

[0054] In the above embodiment, when the distributed power cable laying device is in use, the main control board 322 collects real-time data of the start and stop status of the photosensor 34 , the pressure sensor 33 and the motor 311 , and sends the data to the back-end monitoring system through the wireless module 323 .

[0055] In this embodiment, the photosensitive sensor 34 is always running during the whole process. After the photosensitive signal of the photosensitive sensor 34 is sent, the pressure sensor 33 and the electric push rod 312 are successively put into operation. When the set pressure value is reached, the electric push rod 312 stops moving and maintains the current state, and the motor 311 starts. When the cable leaves or detaches from the device, the photosensitive sensor 34 detects a signal, the motor 311 stops, and sends a command to the end monitoring system through the wireless module 323.

[0056] refer to Fig.17 As shown, the power cable laying mechanism 3 also includes a device protection system; the device protection system is used to detect the current of each component to determine the real-time status of each sensor. The photosensitive sensor 34 continues to operate. If the photosensitive sensor 34 itself fails due to power failure, the wireless module 323 uploads the alarm information of the abnormal device to the back-end monitoring system, and alarms through the buzzer of the device itself, which is convenient for on-site operators to locate and find. The photosensitive sensor 34 is normal. After the pressure sensor 33 is started, it receives and detects the pressure sensor current. When the current is not 0, the motor 311 starts. When the motor 311 is blocked or the current is abnormal, the motor 311 stops and alarms through the remote signal unit and the buzzer; when the photosensitive element is activated and the pressure sensor cannot be started, the device alarms.

[0057] Combined with the on-site conditions, when the bending radius of the cable to be laid is too small and exceeds its minimum allowable bending radius, the insulation layer or sheath of the cable may be damaged. This damage may reduce the electrical performance of the cable and may cause short circuits or other safety issues. Improper bending may also affect the electrical characteristics of the cable, such as increasing resistance and reducing signal transmission quality. Cables that are excessively bent are difficult to control during the laying process, which may complicate the installation process and increase the difficulty and time required for construction.

[0058] Cables that are in an unnatural bending state for a long time are prone to fatigue damage, which will accelerate the aging process of the cable and shorten its service life. When the cable is excessively bent, its heat dissipation performance may be affected, especially under high load conditions, which may cause local overheating, thereby affecting the safety and reliability of the cable. In order to avoid these problems, before laying the cable, it is usually necessary to ensure that the cable is in a relaxed state and the bending radius meets the manufacturer's recommended standards. In addition, the correct operating procedures must be followed during the laying process to protect the cable from damage. To this end, the distributed power cable laying device also includes a line-aligning mechanism 6.

[0059] refer to Fig.18 and 19As shown, the line-aligning mechanism 6 is fixed at the front end of the power cable laying mechanism 3, and includes a line-aligning pulley, a transmission worm 61 and a line-aligning motor 62; two line-aligning pulleys are provided, and the two line-aligning pulleys are staggered up and down, and the line-aligning pulley is coaxially provided with a meshing gear 63, and the meshing gear 63 is connected to the line-aligning motor 62 through the transmission worm 61 and the transmission shaft; in order to prevent the cable from being entangled by the meshing gear and the transmission worm 61 during the line-aligning process, a guard plate 64 higher than the line-aligning pulley is provided on both sides of the line-aligning pulley. Since the power of the line-aligning motor 62 in the line-aligning structure is relatively small, it can be directly powered by the battery 325 or equipped with a separate power supply. Although the embodiments of the present invention have been shown and described, it can be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the attached claims and their equivalents.
