Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of electric power engineering, and in particular to an MPP electric power pipe with emergency protection. Background Art
[0002] In modern power transmission systems, MPP power pipes are widely used in various power projects as an important cable protection pipe. However, in actual use, MPP power pipes also face some problems and challenges. Traditional MPP power pipes are often weak at the connection parts and are easily affected by external stress, temperature changes, geological subsidence and other factors, resulting in cracks or even breaks. Once there is a problem at the pipeline connection, it will not only affect the normal transmission of electricity, but may also cause safety accidents and cause harm to the surrounding environment and personnel.
[0003] At present, the protection measures for MPP power pipes are mainly focused on the material selection and installation process of the pipelines. Although these methods have improved the strength and stability of the pipelines to a certain extent, there are still deficiencies when dealing with emergencies. For example, when the pipeline is affected by force majeure factors such as accidental impacts or strong earthquakes, traditional protection measures may not be able to protect the pipeline in a timely and effective manner, resulting in increased damage to the pipeline. With the continuous growth of electricity demand and the increasing complexity of the power system, higher requirements are placed on the reliability and safety of MPP power pipes. Traditional protection methods can no longer meet the needs of modern power engineering. There is an urgent need for a more effective emergency protection device that can respond quickly when problems occur in the pipeline, reinforce and protect the pipeline, prevent the fault from further expanding, and ensure the safety and stability of power transmission.

[0010] In the above-mentioned MPP power pipe with emergency protection, an installation cavity is provided on each of the supporting bases, and two limit grooves are symmetrically provided on the arc frame. A threaded rod is vertically installed in each of the limit grooves, and the lower end of each of the threaded rods extends into the installation cavity and is connected to the installation base shaft through an acceleration gear transmission assembly, and the two acceleration gear transmission assemblies are respectively located in the two installation cavities, and a reinforcing clamping assembly is commonly installed between the two threaded rods.

[0013] In the above-mentioned MPP power pipe with emergency protection, the number of teeth of the driving bevel gear is greater than that of the driven bevel gear.
[0014] In the above-mentioned MPP power pipe with emergency protection, the pitch circle diameter of the second spur gear is smaller than the pitch circle diameter of the first spur gear.

This design ensures that when there is a problem with the pipeline, the two ends of the power pipe will not be separated from the limit plate. Even if the power pipe is broken, it can prevent the power pipe from falling to the outside area and causing safety problems, thereby improving the safety of use.
[0021] 3. While the installation base shaft rotates, the threaded rod rotates through a series of gear transmissions, driving the sliding rod to move downward, so that the clamping seat is clamped on the top of the pipe body. The clamping seat is located between the two locking mechanisms, which further reinforces and protects the pipe body, effectively preventing the pipe body from being damaged due to external stress or abnormal conditions, and enhancing the overall stability of the pipeline.
[0022] 4. The design that the number of teeth of the active bevel gear in the acceleration gear transmission assembly is more than that of the driven bevel gear, and the pitch circle diameter of the second spur gear is smaller than the pitch circle diameter of the first spur gear, realizes the reasonable distribution of transmission acceleration and torque, and improves the response speed and reinforcement effect of the card seat.

DETAILED DESCRIPTION
[0031] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.
[0032] Example
[0033] Reference Figure 1-6 , an MPP power pipe with emergency protection, comprising a driving motor 4, an arc frame 8 and a pipe body, a plurality of mounting bases 5 are symmetrically installed on the side wall of the driving motor 4, each mounting base 5 is provided with a mounting hole, a mounting base shaft 18 is installed on the output shaft of the driving motor 4, a limiting disk 1 is installed on the mounting base shaft 18, an arc-shaped limiting groove 2 is provided on the outer wall of the limiting disk 1, and the pipe body is horizontally arranged in the arc-shaped limiting groove 2, the arc-shaped limiting groove 2 matches the shape of the power pipe, and can stably place the power pipe, providing a basis for subsequent locking and protection, a strain sensor is installed in the limiting disk 1, and the strain sensor is located in the arc-shaped limiting groove 2 and contacts the pipe body, two mounting grooves 9 are symmetrically provided on the limiting disk 1, and each mounting groove 9 is connected to the arc-shaped limiting groove 2, and a locking mechanism is installed on each mounting groove 9, and the mounting groove 9 provides an installation space for the locking mechanism, so that the arc-shaped locking seat 12 can quickly clamp the power pipe when needed;
[0034] The locking mechanism includes two push frames 11 that are symmetrically rotatably connected, and each push frame 11 is rotatably connected to the inner wall driven by the installation groove 9. A reset spring 13 is installed between the two push frames 11. The reset spring 13 maintains the position of the push frame 11 in the initial state. When the power pipe needs to be clamped, it can provide a certain elastic buffer to ensure that the clamping force is moderate. At the same time, it is convenient for the device to restore to the initial state after the fault is eliminated. An arc-shaped locking seat 12 is installed on each push frame 11, and the two arc-shaped locking seats 12 corresponding to the position are against each other, and the arc-shaped locking seat 12 is clamped outside the pipe body. The push frame 11 and the arc-shaped locking seat 12 can be driven by the motor. 4 is driven to quickly approach and clamp the power pipe to prevent the power pipe from escaping from the limit plate 1 when a fault occurs, so as to avoid safety problems caused by falling. The pushing frame 11 includes a vertical mounting portion and a vertical pushing portion, and the arc locking seat 12 and the reset spring 13 are both installed on the vertical mounting portion, and the vertical mounting portion is rotatably connected to the inner wall of the mounting groove 9 through a pin shaft. The vertical pushing portion is vertically arranged on the vertical mounting portion, and an inclined surface is provided on the vertical pushing portion, and the limiting cylinder 7 is against the inclined surface. The limiting cylinder 7 cooperates with the pushing frame 11, and guides the movement direction of the pushing frame 11 by abutting against the inclined surface on the pushing frame 11, so as to ensure that the arc locking seat 12 can accurately clamp the power pipe;
[0035] Two supporting bases 3 are symmetrically installed at the lower end of the arc frame 8, and one of the supporting bases 3 is fixedly connected to the driving motor 4 through a connecting plate, and the limit plate 1 is located between the two supporting bases 3, and two supporting brackets 6 are symmetrically installed on the outer wall of each supporting base 3, and a limiting cylinder 7 is installed on each supporting bracket 6, and each pushing frame 11 is against the limiting cylinder 7 at the corresponding position.
[0036] Each supporting base 3 is provided with a mounting cavity 19, and two limiting grooves 14 are symmetrically provided on the arc frame 8. A threaded rod 15 is vertically installed in each limiting groove 14. The lower end of each threaded rod 15 extends into the mounting cavity 19 and is connected to the mounting base shaft 18 through an acceleration gear transmission assembly. The two acceleration gear transmission assemblies are respectively located in the two mounting cavities 19. The acceleration gear transmission assembly includes an active bevel gear 10, and the active bevel gear 10 is installed in the mounting cavity 19. The mounting cavity 19 A transmission shaft 20 is installed on the inner top wall, and a first spur gear 22 and a driven bevel gear 23 are installed on the transmission shaft 20 from top to bottom, and the driven bevel gear 23 is meshed with the active bevel gear 10, and the number of teeth of the active bevel gear 10 is more than that of the driven bevel gear 23. The lower end of each threaded rod 15 extends into the mounting cavity 19 and is installed with a second spur gear 21, and the second spur gear 21 is meshed with the first spur gear 22, and the pitch circle diameter of the second spur gear 21 is smaller than the pitch circle diameter of the first spur gear 22.
[0037] A reinforcing clamping assembly is installed between the two threaded rods 15, and the reinforcing clamping assembly includes two symmetrically arranged sliding rods 17, and each sliding rod 17 is slidably connected to the corresponding limit groove 14, and each sliding rod 17 is threadedly connected to the corresponding threaded rod 15, and a clamping seat 16 is installed between the two sliding rods 17, and the clamping seat 16 is clamped on the top of the pipe body, through threaded connection and gear transmission, the up and down movement of the clamping seat 16 can be accurately controlled, and the power pipe can be further reinforced and protected when necessary. It can withstand greater force to ensure the clamping effect of the clamping seat 16 on the power pipe. The clamping seat 16 is made of insulating material, which can effectively prevent the power pipe from leaking electricity and causing harm to the surrounding environment and personnel, thereby improving safety. The clamping seat 16 is clamped above the power pipe and cooperates with the arc locking seat 12 to provide double protection for the power pipe, thereby enhancing the protection effect of the device.
[0038] In the initial state, the pushing frame 11 does not contact the limiting cylinder 7, and there is a certain gap between the two arc-shaped locking seats 12 in corresponding positions and they do not contact and abut against the outer surface of the pipe body. The two pipe connections of the MPP power pipe are located between the two locking mechanisms. When cracks or breaks occur at the pipe connections of the two MPP power pipes, the strain sensor senses the local strain changes of the pipes, and the strain sensor transmits the data to the terminal controller. The drive motor 4 is turned on by the terminal controller, and the output shaft of the drive motor 4 rotates through the limiting disk 1 brought by the mounting base shaft 18. During the rotation of the limiting disk 1, the pushing frame 11 is driven to rotate, and the inclined surface on the pushing frame 11 abuts against the limiting cylinder 7 and approaches each other, and the reset spring 13 is compressed until the two locking seats 12 approach each other and clamp the power pipe (such as Figure 1 , Figure 2 As shown), ensure that both ends of the power pipe will not be separated from the limit plate 1, reduce the increase of the cracks in the power pipe, and if the power pipe breaks, avoid the power pipe from being separated from the limit plate 1 and falling to the outside area to cause safety problems;
[0039] During the rotation of the mounting base shaft 18, the active bevel gear 10 mounted thereon rotates accordingly, and the active bevel gear 10 drives the driven bevel gear 23 to rotate, and the driven bevel gear 23 drives the first spur gear 22 to rotate through the transmission shaft 20, and the first spur gear 22 drives the second spur gear 21 to rotate, thereby causing the threaded rod 15 to rotate. Since the sliding rod 17 is threadedly connected to the threaded rod 15 and is slidably connected in the limit groove 14, the rotation of the threaded rod 15 will cause the two sliding rods 17 to move downward, thereby driving the clamping seat 16 to move downward. The clamping seat 16 is clamped above the pipe body. At this time, the clamping seat 16 is located between the two locking mechanisms, which further reinforces and protects the pipe body to prevent the pipe body from being damaged due to external stress or abnormal conditions.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
