Description

Technical Field

[0001] This utility model relates to the field of cement pole technology, specifically to a cement pole designed to withstand lightning strikes. Background Technology

[0002] Concrete poles are essential infrastructure for power transmission and distribution systems, primarily used to support power lines and various electrical equipment. They are typically made of concrete, possessing high strength and durability, making them suitable for use in diverse environmental conditions.

[0003] For example, the lightning protection cement pole disclosed in authorization announcement number CN217538118U includes a cement pole with an internal mounting base. A lightning rod is installed on the top of the mounting base. A traction box is installed on the side wall of the cement pole near the bottom. A winding device is installed inside the traction box, and a traction wire is connected to the outside of the winding device. The beneficial effects of this utility model are: by rotating the winding device, the lightning rod can be easily raised to a higher position. When electrical workers install the lightning rod on the top of the cement pole, they do not need to work on the top of the cement pole to install the lightning rod, reducing the difficulty of installing the lightning rod on the cement pole, facilitating the maintenance of the cement pole, and improving the personal safety of electrical workers.

[0004] Although the aforementioned patent allows for the installation of lightning rods, reducing the difficulty of installing lightning rods on cement poles, the lightning rod rises and falls inside the pole. When dust accumulates inside the rising and falling groove, the lightning rod will be unable to rise or fall. Utility Model Content

[0005] The purpose of this invention is to provide a lightning-proof cement pole to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A type of lightning-proof cement pole, including

[0008] The pole body has a vertically arranged side groove on one side of the pole body, a movable block is movably installed inside the side groove, and a lightning protection mechanism is arranged on the outside of the movable block.

[0009] A winding mechanism is provided inside the pole body, a guiding mechanism is provided at the upper end of the pole body, and a pulling mechanism is provided between the winding mechanism and the movable block.

[0010] Preferably, the lightning protection mechanism includes a mounting frame, which is fixedly installed on the outside of the movable block, and a lightning rod body is installed at the top of the mounting frame;

[0011] Preferably, guide grooves are provided on both sides of the inner side groove, and guide blocks are provided on both sides of the movable block, the guide blocks matching the guide grooves;

[0012] Preferably, the winding mechanism includes a motor, which is disposed inside the lower part of the pole body, and a winch is disposed at the output shaft end of the motor;

[0013] Preferably, the pulling mechanism includes a lifting head, which is provided at the top center of the movable block, and the lifting head is connected to the winch by an insulated rope;

[0014] Preferably, the guiding mechanism includes a guide wheel, which is movably mounted on the upper part of the inside of the pole body, and a roller is provided on the right side of the top of the side groove. The insulating pull rope is slidably connected to the roller and the guide wheel.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this type of lightning protection cement pole, when installing the lightning rod body, the motor is started. After the motor starts, it drives the winch to reverse. When the winch reverses, the insulated pull rope wound on it is released. After the insulated pull rope is released, it slides along the guide wheel and controls the hoisting head to descend. When the hoisting head descends, it controls the movable block to descend along the inside of the side groove. When the movable block descends, the guide blocks on both sides of it will slide and guide along the inside of the guide groove. In this way, the mounting frame on one side of the movable block will drive the lightning rod body to descend synchronously, which makes maintenance or replacement more convenient and efficient.

[0017] 2. In this type of lightning protection cement pole, the side groove is set on the outside of the pole body, and the upper end of the side groove is provided with an opening. When the side groove is covered with dust, rainwater can wash into the side groove and automatically clean the dust on its surface, so as not to affect the normal raising and lowering of the lightning rod body.

[0023] 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.

[0024] like Figure 1-4 As shown, this utility model provides a technical solution:

[0025] A lightning-proof cement pole includes a pole body 1. A side groove 2 is vertically arranged on the outer side of one side of the pole body 1. A movable block 3 is movably installed inside the side groove 2. A lightning protection mechanism is arranged on the outer side of the movable block 3. The lightning protection mechanism includes a mounting frame 4, which is fixedly installed on the outer side of the movable block 3. A lightning rod body 5 is arranged at the top of the mounting frame 4. Guide grooves 6 are formed on both sides of the inner side groove 2. Guide blocks 7 are arranged on both sides of the movable block 3, and the guide blocks 7 match the guide grooves 6. A winding mechanism is arranged inside the pole body 1, and the winding mechanism includes a motor 8. A motor 8 is installed at the lower interior of the pole body 1. A winch 9 is installed at the output shaft end of the motor 8. A guide mechanism is installed at the upper end of the pole body 1. The guide mechanism includes a guide wheel 12. The guide wheel 12 is movably installed at the upper interior of the pole body 1. A roller 13 is installed on the right side of the top of the side groove 2. An insulated pull rope 11 is slidably connected to the roller 13 and the guide wheel 12. A pulling mechanism is installed between the winding mechanism and the movable block 3. The pulling mechanism includes a lifting head 10. The lifting head 10 is installed at the middle of the top of the movable block 3. The lifting head 10 is connected to the winch 9 through the insulated pull rope 11.

[0026] Working principle: When installing the lightning rod body 5, the motor 8 is started. After the motor 8 starts, it drives the winch 9 to reverse. When the winch 9 reverses, the insulated pull rope 11 wound on it is released. After the insulated pull rope 11 is released, it slides along the guide wheel 12 and controls the hoisting head 10 to descend. When the hoisting head 10 descends, it controls the movable block 3 to descend along the inside of the side groove 2. When the movable block 3 descends, the guide blocks 7 on both sides of it will slide along the inside of the guide groove 6. In this way, the mounting bracket 4 on one side of the movable block 3 will drive the lightning rod body 5 to descend synchronously. This makes maintenance or replacement more convenient and efficient. Moreover, the side groove 2 is set on the outside of the pole body 1, and the upper end of the side groove 2 is provided with an opening. When the side groove 2 is contaminated with dust, rainwater can wash into the side groove 2 and automatically clean the dust on its surface. This will not affect the normal raising and lowering of the lightning rod body 5.
