Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete electric poles, in particular to a prefabricated concrete electric pole. Background Art
[0002] As the name suggests, telephone poles are poles for hanging electric wires. They appear in every rural area, field, road and street, and are one of the important infrastructures in early China. Various early telephone poles all started out as wooden poles, even including high-voltage poles with voltage levels that were not too high. Later, due to the development of steel and reinforced concrete, and technical requirements, these two materials replaced most wooden poles.
[0003] However, most of the existing concrete utility poles are in the shape of a truncated cone from top to bottom. When installing, a foundation pit is usually dug at the installation location, and the utility pole is erected in the pit to be fixed. The utility pole body lacks a supporting structure, resulting in poor anti-toppling ability and low stability of the utility pole. The use of a fixing device and a reinforcement device in the utility model can effectively prevent the utility pole from toppling, and the setting of the base improves the stability of the utility pole in use. Utility Model Content
[0004] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.
[0005] In order to solve the technical problems mentioned in the above background technology part, some embodiments of the present application provide a precast concrete electric pole, including a concrete pole, a base, a fixing device, and a reinforcement device; the base is inserted into the ground, the fixing device is used for fixed connection of the concrete pole and the base, and the reinforcement device is used for reinforcing the concrete pole and the base; the concrete pole includes a pole body and a connecting block fixed at the lower end of the pole body; the base includes a seat body and a plurality of fasteners fixed at the bottom of the seat body for inserting into the soil; the fixing device includes a connecting seat fixed on the base, a first clamping block rotatably arranged in the connecting seat, a second clamping block rotatably arranged in the connecting seat, a spring with one end fixed on the first clamping block and the other end fixed on the second clamping block, a pushing block fixed on the second clamping block, and a threaded rod rotatably arranged on the first clamping block.
[0006] Specifically, the connecting block includes a body, a first plane and a second plane symmetrically arranged on the body, a first inclined surface located below the first plane and arranged on the body, and a second inclined surface located below the second plane and arranged on the body; the first inclined surface and the second inclined surface are symmetrically arranged;
[0007] Specifically, the first clamping block includes a first block, a first rough plane arranged on the first block, and a first rough inclined plane located below the first rough plane and arranged on the first block; the second clamping block includes a second block, a second rough plane arranged on the second block, and a second rough inclined plane located below the second rough plane and arranged on the second block; the first rough plane and the second rough plane are symmetrically arranged, and the first rough inclined plane and the second rough inclined plane are symmetrically arranged.
[0008] Specifically, the reinforcement device also includes a first reinforcement ring movably arranged on the first guide rod, a second reinforcement ring arranged on the second guide rod, a first connecting rod with one end rotatably arranged on the base and the other end rotatably arranged on the first reinforcement ring, a second connecting rod with one end rotatably arranged on the base and the other end rotatably arranged on the second reinforcement ring, a first steel wire with one end fixedly arranged on the bottom of the first clamping block and the other end fixedly arranged on the first reinforcement ring, and a second steel wire with one end fixedly arranged on the bottom of the second clamping block and the other end fixedly arranged on the second reinforcement ring; the first reinforcement ring and the second reinforcement ring are symmetrically arranged.
[0009] Specifically, the reinforcement device also includes a first slide groove arranged on the connecting seat, a second slide groove arranged on the connecting seat, a first slider movably arranged in the first slide groove, a second slider movably arranged in the second slide groove, a first guide rod one end of which is fixed on the first slider and passes through a first reinforcement ring that can be movably arranged, and a second guide rod one end of which is fixed on the second slider and passes through a second reinforcement ring that can be movably arranged.
[0010] The beneficial effects of the utility model are:
[0011] During installation, the base is inserted into the fixed position, the concrete rod and the base are connected and fixed, and the concrete rod is placed in the fixing device. At this time, the first clamping block and the second clamping block in the connecting seat are in a relaxed state, and the threaded rod arranged on the first clamping block is rotated, so that the first clamping block is rotated inwardly, and under the action of the spring, the second clamping block also approaches the connecting block. When one end of the threaded rod contacts the pushing block on the second clamping block and completely abuts against the pushing plate, the first clamping block and the second clamping block completely clamp the connecting block to achieve fixation; at the same time, when the first clamping block and the second clamping block move toward each other, the first steel wire arranged at the bottom of the first clamping block and the second steel wire arranged at the bottom of the second clamping block are driven to move, thereby triggering the first reinforcement ring and the second reinforcement ring to move toward each other, and the matching rod of the first connecting rod arranged on the base at one end is rotated and the matching rod of the first connecting rod arranged on the first reinforcement ring at the other end is rotated When the first and second clamps are closed, a continuous downward force is generated, which drives the first slider on the first guide rod to slide stably inward in the slide groove, giving the first reinforcement ring a continuous inward thrust. Similarly, the working path of the second reinforcement ring can be obtained. When the first clamp and the second clamp are fixed, the steel wire remains in a tensioned state, so that the first reinforcement ring and the second reinforcement ring are closed to complete the reinforcement. Traditional concrete telephone poles are mostly in the shape of a truncated cone from top to bottom. When installed, a foundation pit is usually dug at the installation location, and the telephone pole is erected in the pit to fix it. The telephone pole body lacks a supporting structure, resulting in poor anti-tilting ability and low stability of the telephone pole. The above-mentioned setting uses a fixing device and a reinforcement device to effectively prevent the telephone pole from tipping over, avoid being blown down in severe weather and strong winds, and at the same time avoid tilting, thereby improving the stability of the utility model.

[0025] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.
[0026] Reference Figure 1-6As shown, a precast concrete electric pole described in the utility model comprises a concrete pole 1, a base 2, a fixing device 3, and a reinforcing device 4; the base 2 is inserted into the ground, the fixing device 3 is used for fixed connection of the concrete pole 1 and the base 2, and the reinforcing device 4 is used for reinforcing the concrete pole 1 and the base 2; the concrete pole comprises a pole body 11, a connecting block 12 fixedly arranged at the lower end of the pole body; the base comprises a seat body 21, and a plurality of fastening members 22 fixedly arranged at the bottom of the seat body for inserting into the soil; the fixing device 3 comprises a connecting seat 31 fixedly arranged on the base, a first clamping block 32 rotatably arranged in the connecting seat, a second clamping block 33 rotatably arranged in the connecting seat, a spring 34 with one end fixedly arranged on the first clamping block and the other end fixedly arranged on the second clamping block, a pushing block 35 fixedly arranged on the second clamping block, and a threaded rod 36 rotatably arranged on the first clamping block.
[0027] During installation, the base is inserted into the fixed position, the concrete rod and the base are connected and fixed, and the concrete rod is placed in the fixing device. At this time, the first clamping block and the second clamping block in the connecting seat are in a relaxed state, and the threaded rod arranged on the first clamping block is rotated, so that the first clamping block is rotated inwardly, and under the action of the spring, the second clamping block also approaches the connecting block. When one end of the threaded rod contacts the pushing block on the second clamping block and completely abuts against the pushing plate, the first clamping block and the second clamping block completely clamp the connecting block to achieve fixation; at the same time, when the first clamping block and the second clamping block move toward each other, the first steel wire arranged at the bottom of the first clamping block and the second steel wire arranged at the bottom of the second clamping block are driven to move, thereby triggering the first reinforcement ring and the second reinforcement ring to move toward each other, and the matching rod of the first connecting rod arranged on the base at one end is rotated and the matching rod of the first connecting rod arranged on the first reinforcement ring at the other end is rotated When the first and second clamps are closed, a continuous downward force is generated, which drives the first slider on the first guide rod to slide stably inward in the slide groove, giving the first reinforcement ring a continuous inward thrust. Similarly, the working path of the second reinforcement ring can be obtained. When the first clamp and the second clamp are fixed, the steel wire remains in a tensioned state, so that the first reinforcement ring and the second reinforcement ring are closed to complete the reinforcement. Traditional concrete telephone poles are mostly in the shape of a truncated cone from top to bottom. When installed, a foundation pit is usually dug at the installation location, and the telephone pole is erected in the pit to fix it. The telephone pole body lacks a supporting structure, resulting in poor anti-tilting ability and low stability of the telephone pole. The above-mentioned setting uses a fixing device and a reinforcement device to effectively prevent the telephone pole from tipping over, avoid being blown down in severe weather and strong winds, and at the same time avoid tilting, thereby improving the stability of the utility model.
[0028] Specifically, the connecting block 12 includes a body 121, a first plane 122 and a second plane 123 symmetrically arranged on the body, a first inclined surface 124 located below the first plane and arranged on the body, and a second inclined surface 125 located below the second plane and arranged on the body. ；The first inclined surface and the second inclined surface are symmetrically arranged; the arrangement of multiple surfaces on the connecting block increases the contact area with the fixing device, thereby making the fixing more stable.

Similarly, the second rough plane of the second clamp contacts the second plane of the connecting block, and the second rough inclined surface contacts the second inclined surface. The symmetrical arrangement of multiple rough surfaces increases the friction during connection, thereby making the fixing device more firmly fixed during operation.
[0030] Specifically, the reinforcement device 4 also includes a first slide groove 41 provided on the connecting seat 31, a second slide groove 42 provided on the connecting seat, a first slider 43 movably provided in the first slide groove, a second slider 44 movably provided in the second slide groove, a first guide rod 45 having one end fixed on the first slider and passing through a first reinforcement ring movably provided, and a second guide rod 46 having one end fixed on the second slider and passing through a second reinforcement ring movably provided; during the operation of the reinforcement device, the first guide rod drives the first slider to slide in the first slide groove, providing the reinforcement device with a support while providing the reinforcement device with a path for continuous inward movement, so that the execution degree of the reinforcement device is higher.
[0031] Specifically, the reinforcement device 4 also includes a first reinforcement ring 47 movably arranged on the first guide rod, a second reinforcement ring 48 arranged on the second guide rod, a first connecting rod 49 with one end rotatably arranged on the base and the other end rotatably arranged on the first reinforcement ring, a second connecting rod 410 with one end rotatably arranged on the base and the other end rotatably arranged on the second reinforcement ring, a first steel wire 411 with one end fixedly arranged on the bottom of the first clamping block and the other end fixedly arranged on the first reinforcement ring, and a second steel wire 412 with one end fixedly arranged on the bottom of the second clamping block and the other end fixedly arranged on the second reinforcement ring; the first reinforcement ring and the second reinforcement ring are symmetrically arranged; when the first clamping block moves, The first guide rod drives the first slider to move in the first slide groove in the connecting seat, and provides a continuous inward force to the first reinforcement ring while supporting the first reinforcement ring.
