Description

Technical Field

[0001] The utility model relates to the technical field of concrete poles, in particular to a special high-strength prestressed concrete pole. Background Art

[0002] Prestressed concrete poles are made by pre-tensioning the steel bars during the pole manufacturing process, creating a pre-compressive stress in the concrete before it bears any load. When the pole bends under load, the pre-compressive stress in the tensioned area makes it less likely to crack, thereby increasing the pole's load-bearing capacity and service life.

[0003] Concrete poles are prone to breaking during installation or when impacted. Conventional concrete poles lack a structure to guide and buffer external impact forces, so external impact forces act directly on the poles, easily damaging them. Furthermore, most concrete poles are simply mounted directly on their bases, making them unstable. In windy weather, the poles can topple over due to the force of the wind, posing a safety hazard. Therefore, a special high-strength prestressed concrete pole was proposed to address these issues. Utility Model Content

[0004] The purpose of the utility model is to provide a special high-strength prestressed concrete pole to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a special high-strength prestressed concrete pole, comprising a pole body, a protective mechanism is provided on the outside of the pole body, and a stabilizing mechanism is provided on the outside of the pole body;

[0006] The protection mechanism includes a base block, a fixed cylinder is fixedly connected to the outside of the base block, a slider is slidably connected to the inside of the fixed cylinder, a spring is fixedly connected to one side of the slider, a movable cylinder is fixedly connected to the other side of the slider, and a protective plate is fixedly connected to the side of the movable cylinder away from the slider;

[0007] The stabilizing mechanism includes a support tube, the outer side of the support tube is fixedly connected to a support block, and the bottom of the support block is fixedly connected to a base.

[0008] Preferably, the base block is fixedly connected to the outside of the pole body, a cylindrical through-hole adapted to the pole body is provided inside the base block, and the side surface of the base block is rectangular.

[0009] Preferably, the fixing cylinders are fixedly connected to the four side surfaces of the base block, and a single side surface of the base block is fixedly connected to three fixing cylinders that are evenly spaced vertically.

[0010] Through the above technical solution, the fixing cylinder is installed on the four sides of the base block, which can facilitate the subsequent installation of the protective plate.

[0011] Preferably, a sliding groove adapted to the moving track of the slider is provided inside the fixed cylinder, a through hole adapted to the movable cylinder is provided on one side of the fixed cylinder, and the sliding groove is communicated with the through hole.

[0012] Through the above technical solution, the provision of the slide groove limits the moving direction and moving distance of the slider, the movable cylinder and the protective plate, and the provision of the through hole facilitates the movement of the movable cylinder.

[0013] Preferably, the number of the protective plates is four and they are centrally symmetrically distributed on the outside of the pole body, and the protective plates are made of aluminum alloy.

[0014] Through the above technical solution, four protective plates distributed symmetrically in the center can provide all-round protection for the lower end of the pole body to prevent foreign objects from hitting the pole body and causing damage. The aluminum alloy material makes the protective plate low in density and high in strength, which not only reduces the weight of the protective plate but also ensures sufficient protective strength. In addition, the surface of the aluminum alloy material is easy to form a dense oxide film, which can make the protective plate have good corrosion resistance.

[0015] Preferably, a first thread is provided on the outer side of the pole body, and a second thread engaged with the first thread is provided inside the support tube.

[0016] Through the above technical solution, the support tube and the pole body can be quickly installed or disassembled by using the first thread and the second thread in coordination.

[0017] Preferably, the support block is designed as a triangular block, and a third threaded through hole is provided on the base, and a bolt adapted thereto is threadedly connected to the third threaded through hole.

[0018] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0019] First, when the lower end of the pole body is hit by an external object, the object will hit the four protective plates distributed symmetrically in the center, causing the slider to slide toward the inside of the fixed tube, compressing the spring. The spring undergoes elastic deformation during the collision, converting the impact force into elastic potential energy of the spring, thereby effectively reducing the damage to the pole body caused by the collision of external objects and playing a protective role.

[0020] Second, the utility model installs the support tube on the outside of the pole body through threads, and then installs the base at a predetermined position through bolts. The triangular block-shaped support block on the top of the base plays a role in firmly supporting the pole body. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The base block 21 is fixedly connected to the outside of the pole body 1 . A cylindrical through-hole matching the pole body 1 is provided inside the base block 21 . The side surface of the base block 21 is rectangular.

[0032] The fixing cylinders 22 are fixedly connected to the four side surfaces of the base block 21 , and a single side surface of the base block 21 is fixedly connected to three fixing cylinders 22 that are evenly spaced vertically.

[0033] A sliding groove adapted to the moving track of the slider 23 is provided inside the fixed cylinder 22 , and a through hole adapted to the movable cylinder 25 is provided on one side of the fixed cylinder 22 , and the sliding groove is communicated with the through hole.

[0034] There are four protective plates 26 , which are centrally symmetrically distributed on the outer side of the pole body 1 . The protective plates 26 are made of aluminum alloy.

[0035] Through the above technical solution, when the surface of the pole body 1 is hit by a foreign object, the object will hit the four protective plates 26 distributed symmetrically with the center, causing the slider 23 to slide toward the inside of the fixed tube 22, compressing the spring 24. The spring 24 undergoes elastic deformation during the collision, converting the impact force into the elastic potential energy of the spring 24, thereby effectively reducing the damage to the pole body 1 caused by the collision of foreign objects and playing a protective role.

[0036] Example 2

[0037] See also Figure 1 and Figure 4 , and on the basis of embodiment 1, it is further obtained that: the outer side of the pole body 1 is movably connected with a stabilizing mechanism 3;

[0038] The stabilizing mechanism 3 includes a support tube 31 , an outer side of the support tube 31 is fixedly connected to a support block 32 , and a bottom of the support block 32 is fixedly connected to a base 33 .
