Description

Technical Field

[0001] The invention belongs to the technical field of electric pole protection equipment, and in particular relates to a positioning device for preventing electric poles from being pulled up and displaced in winter. Background Art

[0002] Winters in northern regions are often extremely cold, and the soil freezes easily. These regions experience long, cold winters, and moisture in the soil freezes and expands at low temperatures, generating a powerful frost heave force. This frost heave force poses a significant challenge to electric poles embedded in the soil. As the volume of water in the soil expands after freezing in winter, the poles can be lifted upward by the frost heave. This phenomenon is particularly common in cold regions, especially those with thick permafrost. Frost heave occurs when the permafrost reaches a certain thickness, and the bond between the permafrost and the pole exceeds the total load on the pole shaft. This causes the concrete pole to be pulled up, creating a cavity below the pole base that is immediately filled with unfrozen mud, water, sand, and gravel. After thawing the following year, the pole shaft cannot return to its original position, resulting in the pole being lifted upward year after year. This phenomenon requires prompt action to prevent it from causing safety hazards, such as line breakage, tilted poles, or even pole collapse. Summary of the Invention

[0006] The connecting platforms are evenly distributed on the outside of the bottom bracket, and the contact sides between the connecting platforms and the bottom bracket are inclined.

[0007] A clamping strip is provided on the outside of the bottom bracket, and a clamping slot is provided on the outside of the connecting platform, and the clamping strip and the clamping slot cooperate with each other.

[0008] The clamping block is arc-shaped, and a non-slip layer is provided on the surface of the clamping block.

[0009] A limited motion mechanism is provided on the outside of the filling seat, and the limited motion mechanism includes a lower tooth plate, an upper tooth plate and a fixed gear. The lower tooth plate and the upper tooth plate are both engaged with the fixed gear. The lower tooth plate is fixedly connected to the connecting platform, and a plug is provided at the end of the upper tooth plate.

[0010] A sliding groove is provided inside the base, and sliding blocks are provided at the bottom of the lower tooth plate and the bottom of the upper tooth plate.

[0011] A monitoring mechanism is provided on the upper side of the landfill seat, and the monitoring mechanism includes a vertical tube and a monitoring tube. The monitoring tube is located above the vertical tube, and a lifting plate is clamped inside the vertical tube. A lifting spring is provided between the lifting plate and the vertical tube, a pull rope is fixedly provided at the bottom of the lifting plate, and a guide pulley is provided below the lifting plate.

[0012] The monitoring tube is made of a transparent acrylic plate, and scale lines are provided on the surface of the monitoring tube.

[0013] The present invention provides a positioning device for preventing electric poles from being pulled up and displaced in winter, which has the following beneficial effects: The present invention is exquisitely designed and highly targeted, and is particularly suitable for winter or other environments where the soil is easily frozen, to ensure the stability and safety of the electric poles. The combined design of the base and the ring tube provides a solid support platform for the bottom of the electric pole. The wrapping structure of the buried seat can effectively reduce the direct contact between the electric pole and the surrounding soil, reduce the impact of soil frost heave on the electric pole, and thus significantly improve the stability of the electric pole under severe weather conditions such as winter. The synergistic effect of the connecting platform, the vertical plate, the clamping block and the base forms a stable clamping system. Under normal circumstances, the clamping block can fit tightly against the electric pole. When the electric pole is pulled up due to the frost heave force of the soil, the reset spring will push the connecting platform closer to the electric pole, further increasing the clamping force of the clamping block on the electric pole, and can provide a certain resistance when the electric pole is subjected to the upward pulling force, further enhancing the pull-out resistance. The interlocking lower and upper tooth plates and fixed gear in the restraining mechanism, along with the plug at the end of the upper tooth plate, create a double locking effect. When the pole moves upward due to soil frost heave, the plug extends from the inner base, ensuring the overall stability of the device. The monitoring mechanism allows for real-time monitoring of the pole's stability, preventing major accidents. This device effectively prevents pole displacement caused by soil frost heave, thaw, or wind, ensuring the continuity and safety of power transmission. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention. Example

[0024] See also Figures 1 to 5A positioning device for preventing electric poles from being pulled up and displaced in winter, comprising a landfill seat 1 and an electric pole 3. A shell 4 is provided on the outside of the landfill seat 1, a pole entry port 5 is provided on the upper side of the shell 4, the electric pole 3 is inserted into the landfill seat 1 through the pole entry port 5, a bottom support 6 is provided in the middle of the shell 4, a ring tube 7 is provided on the upper side of the bottom support 6, the bottom of the electric pole 3 is placed inside the ring tube 7, a connecting platform 8 is provided around the outside of the bottom support 6, a vertical plate 9 is fixed on the upper side of the connecting platform 8, a clamping block 10 is provided inside the vertical plate 9, the connecting platform 8 is connected to the base 15 through a limiting plate 14, and a reset spring 13 is provided between the base 15 and the connecting platform 8.

[0025] The upper side of the landfill seat 1 is located at a frozen soil layer 2 .

[0026] The connecting platforms 8 are evenly distributed on the outside of the base 6 , and the contact sides between the connecting platforms 8 and the base 6 are inclined.

[0027] A clamping strip 11 is provided on the outer side of the base 6 , and a clamping slot 12 is provided on the outer side of the connecting platform 8 . The clamping strip 11 and the clamping slot 12 cooperate with each other.

[0028] The clamping block 10 is arc-shaped, and a non-slip layer is provided on the surface of the clamping block 10 .

[0029] When using the device, the landfill seat 1 is installed and excavated to a depth below the frozen soil layer 2. The electric pole 3 is placed into the landfill seat 1 along the pole entry 5 until the bottom of the electric pole 3 is completely inside the ring tube 7. Under the action of the weight of the electric pole 3, the electric pole 3 will drive the bottom bracket 6 downward, and the bottom bracket 6 will push the connecting platform 8 outward. The connecting platform 8 drives the vertical plate 9 and the clamping block 10 to maintain a suitable distance from the electric pole 3. Then, the landfill seat 1 and the electric pole 3 can be buried. When cold weather arrives, the frozen soil layer 2 above the landfill seat 1 will freeze. At this time, the frozen soil layer 2 will exert a frost heave force on the electric pole 3, pulling the electric pole 3 upward. During the upward pulling process, the return spring 13 will push the connecting platform 8 closer to the bottom bracket 6, thereby driving the vertical plate 9 and the clamping block 10 to clamp the electric pole 3. The greater the distance the electric pole 3 is pulled up, the greater the clamping force of the clamping block 10 on the electric pole 3, which can effectively limit the upward pulling range of the electric pole 3. When the temperature rises, the frost heave force of the frozen soil layer 2 on the pole 3 disappears. Since the bottom of the pole 3 and the base 6 are not buried with sand and gravel, the pole 3, under its own weight, will drive the base 6 to fall back to its original position. This device has shown significant effects in improving the stability of the pole, enhancing its pull-out resistance, adaptive adjustment, facilitating installation and maintenance, and improving safety.

[0031] Furthermore, the upper side of the landfill seat 1 is the frozen soil layer 2. The landfill seat 1 is located below the frozen soil layer 2, and the frozen soil layer 2 will not cause frost heave and pull-up effect on the landfill seat 1.

[0032] Furthermore, the connecting platforms 8 are evenly distributed on the outside of the base 6, and the contact sides between the connecting platforms 8 and the base 6 are inclined. There are multiple connecting platforms 8, which are evenly placed on the outside of the base 6, and the outsides of the connecting platforms 8 and the outsides of the base 6 are both inclined surfaces.

[0033] Furthermore, a clip strip 11 is provided on the outside of the base 6, and a slot 12 is provided on the outside of the connecting platform 8. The clip strip 11 and the slot 12 cooperate with each other. The base 6 is connected to the slot 12 of the connecting platform 8 by the clip strip 11 to prevent the base 6 and the connecting platform 8 from deviating.

[0034] Furthermore, the clamping block 10 is arc-shaped and has an anti-skid layer on its surface. The arc-shaped clamping block 10 can fit the pole 3 more closely, and the anti-skid layer is used to increase the friction between the clamping block 10 and the pole 3.

[0035] Furthermore, a limited motion mechanism 16 is provided on the outside of the landfill seat 1, and the limited motion mechanism 16 includes a lower tooth plate 19, an upper tooth plate 20 and a fixed gear 18. The lower tooth plate 19 and the upper tooth plate 20 are both engaged with the fixed gear 18. The lower tooth plate 19 is fixedly connected to the connecting platform 8, and a plug 17 is provided at the end of the upper tooth plate 20.

[0036] Furthermore, a chute 21 is provided inside the base 15, and a slider 22 is provided at the bottom of the lower tooth plate 19 and the upper tooth plate 20. The lower tooth plate 19 and the upper tooth plate 20 are connected to the chute 21 inside the base 15 through the slider 22.

[0037] When using the device, the landfill seat 1 is installed and excavated to a depth below the frozen soil layer 2. The electric pole 3 is placed into the landfill seat 1 along the pole entry 5 until the bottom of the electric pole 3 is completely inside the ring tube 7. Under the action of the weight of the electric pole 3, the electric pole 3 will drive the bottom bracket 6 downward, and the bottom bracket 6 will push the connecting platform 8 outward. The connecting platform 8 drives the vertical plate 9 and the clamping block 10 to maintain a suitable distance from the electric pole 3. Then, the landfill seat 1 and the electric pole 3 can be buried. When cold weather arrives, the frozen soil layer 2 above the landfill seat 1 will freeze. At this time, the frozen soil layer 2 will exert a frost heave force on the electric pole 3, pulling the electric pole 3 upward. During the upward pulling process, the return spring 13 will push the connecting platform 8 closer to the bottom bracket 6, thereby driving the vertical plate 9 and the clamping block 10 to clamp the electric pole 3. The greater the distance the electric pole 3 is pulled up, the greater the clamping force of the clamping block 10 on the electric pole 3, which can effectively limit the upward pulling range of the electric pole 3. After the temperature rises, the frost heave force of the frozen soil layer 2 on the pole 3 disappears. Since the bottom of the pole 3 and the base 6 are not buried with sand and gravel, the pole 3, under the action of its own weight, will drive the base 6 to fall to its original position. Furthermore, the lower tooth plate 19, the upper tooth plate 20 and the fixed gear 18 in the limiting mechanism 16 are engaged with each other, and the plug 17 at the end of the upper tooth plate 20 is designed to form a double locking effect. Under normal circumstances, the plug 17 retracts into the inside of the shell 4, and the pole 3 is pulled up by the frost heave force. The connecting platform 8 will move closer to the base 6, and the connecting platform 8 drives the lower tooth plate 19 to move inward. The lower tooth plate 19 drives the fixed gear 18 to rotate, and then drives the upper tooth plate 20 to move outward. The upper tooth plate 20 drives the plug 17 to extend out of the shell 4, positioning the buried seat 1, and has a good stabilizing effect. This device has shown significant effects in improving the stability of the pole, enhancing the anti-pullout ability, adaptive adjustment, installation and maintenance convenience, and improving safety.

[0046] Furthermore, the monitoring tube 25 is made of a transparent acrylic plate, and a scale line 32 is provided on the surface of the monitoring tube 25. The pointer 31 can be observed at any time through the monitoring tube 25.

[0047] When using the device, the landfill seat 1 is installed and excavated to a depth below the frozen soil layer 2. The electric pole 3 is placed into the landfill seat 1 along the pole entry 5 until the bottom of the electric pole 3 is completely inside the ring tube 7.

This helps to promptly identify and address potential safety hazards and prevent major accidents. Furthermore, the number of monitoring mechanisms 23 corresponds to the number of connecting platforms 8. Based on the different positions of the pointers 31 of each monitoring mechanism 23, it can be determined whether each connecting platform 8 is at the same height and whether the pole 3 is tilted. This device has demonstrated significant results in improving pole stability, enhancing pullout resistance, adaptive adjustment, facilitating installation and maintenance, and improving safety.
