Description

Technical Field

[0001] The invention relates to an inserted electric pole foundation, belonging to the technical field of power transmission line engineering. Background Art

[0002] Overhead distribution lines are widely used in my country's power system, so it is necessary to ensure the safe operation of the power system and the safety of the environment around the distribution lines. At present, the method of backfilling the foundation pit is mostly used when assembling the poles. The foundation pit is excavated manually, and the foundation under the poles is mostly backfilled directly with the original soil. During the construction process, the pole tower foundation passing through the pole will be fixed to reduce the phenomenon of the pole tipping caused by the external force of the pole tower. However, if the soil bearing capacity is insufficient, the pole may still tilt and settle, which will affect the transmission of electricity in the distribution network, and in severe cases, it will affect the residents' daily electricity consumption.

[0003] A prefabricated assembled pole foundation disclosed in a Chinese utility model patent with publication number CN210946867U includes a pole, a prefabricated pole foundation, and stud bolts. The characteristic is that the prefabricated pole foundation is made of steel bars and concrete, and two groups of bolt holes are arranged horizontally, and a circular arc surface is arranged on the inner side of the center. The pole is clamped by two prefabricated pole foundations, connected by stud bolts passing through the bolt holes, and tightened with gaskets and nuts.

[0004] The above reference example discloses a multi-layered pole foundation, but after being buried in the soil, the pole may still fall over due to land subsidence, and has poor stability. In addition, since the pole foundations are spliced ​​together, the connection stability is poor and it is easy to lose its supporting function, so it is urgently needed to be improved. Summary of the invention

The rotating ring is rotatably sleeved outside the pole body, and a spraying mechanism for spraying herbicides around the pole body is installed outside the rotating ring.

[0015] Furthermore, the spraying mechanism includes an extension rod fixed to the outside of the rotating ring, a liquid storage tank for storing herbicides is fixedly provided on the top of the extension rod, a nozzle for spraying herbicides is installed on the bottom of the extension rod, and the liquid storage tank and the nozzle are connected by a hose.

[0016] Furthermore, the bottom end of the extension rod is fixedly connected to a slide rail arranged in the same direction as the extension rod, a slide rod is slidably installed on the slide rail, the nozzle is fixedly installed at the bottom end of the slide rod, and a reciprocating drive mechanism is provided at the free end of the extension rod for driving the slide rod to perform reciprocating motion on the slide rail.

[0017] Furthermore, the reciprocating drive mechanism comprises a swing rod and a drive assembly, one end of the swing rod is fixedly sleeved with a pin shaft, the pin shaft is driven to rotate by the drive assembly, and the other end of the swing rod is fixedly sleeved with a clamping shaft;

[0019] Further, the driving assembly includes a fixed gear ring and a gear meshed with the fixed gear ring and arranged on the inner side of the fixed gear ring, the gear is fixedly sleeved on the pin shaft, and the top end of the pin shaft is rotatably connected to the bottom of the free end of the extension rod, and the swing rod is spaced apart and arranged at the bottom end of the gear;

[0020] A fixed collar is arranged on the top of the rotating collar and is mounted on the pole body. A plurality of bending rods are evenly fixed on the outside of the fixed collar along the circumferential direction. The free ends of the bending rods are bent downward, and the free ends of the bending rods are fixedly connected to the top of the gear ring.

[0021] Furthermore, the linkage rod is a retractable telescopic rod.

[0022] Compared with the prior art, the present invention has the following characteristics and beneficial effects:

[0023] 1. The present invention provides a pile top clamp, which can make the pole pass through the pile top clamp before installing the pole, thereby effectively aligning the pole to prevent the pole from being tilted during installation, and by fixing the pile top clamp and the steel cage through a connecting rod, the stability of the pile top clamp can be effectively increased, thereby effectively preventing the pole from tilting, which helps to ensure the stability of the pole; at the same time, by providing the upper support column, the pole can be further centered to ensure that the pole is vertical, and at the same time the pole is tightly sleeved by the upper support column, and the upper support column and the soil are fully combined, thereby effectively preventing the pole from settling, and adding a lower support column on the basis of the upper support column increases the burial depth of the entire concrete column, further improves the stability of the concrete column, thereby extending the service life of the pole, improving the stability and safety of the pole, effectively solving the problem of pole settlement and tilting caused by insufficient soil bearing capacity, and is beneficial to the normal operation of the transmission line.

[0024] 2. The present invention, by setting a spraying mechanism, can utilize the rotation of the driving worm gear to drive the rotating ring. During the rotation of the rotating ring, the extension rod will be driven to make a circular motion around the electric pole, thereby causing the gear at the free end of the extension rod to rotate under the meshing action of the fixed gear ring. The gear can synchronously drive the pin shaft to rotate. While the pin shaft rotates, it will also drive the swing rod to rotate with the pin shaft as the rotation center. During the rotation process, the free end of the swing rod will push the limit rod to move through the clamping shaft disposed in the limit groove. Therefore, during the continuous rotation of the swing rod, the clamping shaft continuously drives the sliding rod to make a reciprocating motion on the slide rail, thereby causing the spray head to synchronously make a reciprocating motion. When the extension rod makes a circular motion around the electric pole, the spray head will move back and forth. On the premise of this, the sprinkler head makes reciprocating motion along the slide rail, so that the sprinkler head can not only spray the herbicide around the pole, but also expand the spraying range of the sprinkler head by reciprocating motion along the slide rail, so as to effectively remove the weeds within a certain range near the pole, so as to effectively eliminate the fire hazard around the root of the pole, prevent small animals from building nests at the root of the pole, ensure the tidiness and cleanliness of the root of the pole, prevent the pole from being eroded, and reduce the work intensity of the weeders. The weeders only need to add the herbicide regularly, and the maintenance personnel can also see the situation around the pole at a glance, and more easily approach the pole to conduct inspections and necessary maintenance work.

[0033] The present invention is described in more detail below with reference to the embodiments.

[0034] Embodiment 1

[0035] See also Figure 1 and Figure 2 The inserted pole foundation of this embodiment includes a pole body 1 and a concrete column buried in the soil. The concrete column includes a lower support column 3 and an upper support column 6 that are integrally connected from bottom to top. During construction, the lower support column 3 must be cast first and the upper support column 6 must be cast after the lower support column 3 solidifies.

[0036] The concrete column also includes a steel cage 2 arranged inside the lower support column 3 and the upper support column 6. The steel cage 2 is required to be evenly distributed in the excavated foundation pit and meet the bearing capacity requirements.

[0037] The top of the upper support column 6 is arranged flush with the ground, the bottom end of the pole body 1 is fixedly inserted into the upper support column 6, and the top of the pole body 1 extends out of the upper support column 6 and then extends upward.

[0038] A pile top clamp 4 is sleeved on the pole body 1 above the ground, and eight connecting rods 5 are fixedly connected between the pile top clamp 4 and the top of the steel cage 2. The eight connecting rods 5 are evenly arranged in an array along the circumferential direction.

After the curing is completed, the pile top clamp 4 is installed at the height H2 of the pole body 1 according to the planned height, and then the pole body 1 is placed. The buried depth of the pole body 1 is H2, so that the pile top clamp 4 is located on the ground surface, and the connecting rod 5 and the fixing clip are used to fix the pile top clamp 4 and the steel cage 2, and then the gap is filled with concrete to the ground surface, and cured and solidified.

[0043] Embodiment 2

[0044] See also Figures 3 to 7 The pole body 1 is located on the upper end of the ground and a worm gear 8 is rotatably sleeved on it. A driving device 7 is fixedly installed on the top of the pile top clamp 4. The driving device 7 is transmission-connected with a worm 71 for driving the worm gear 8 to rotate.

[0045] A plurality of linkage rods 9 are evenly and fixedly connected to the top of the worm gear 8 along the circumferential direction. The top of each linkage rod 9 is fixedly connected to a rotating ring 12. The rotating ring 12 is rotatably sleeved outside the pole body 1, and a spraying mechanism 13 for spraying herbicides around the pole body 1 is installed outside the rotating ring 12.

[0046] Furthermore, the spraying mechanism 13 includes an extension rod 15 fixed to the outside of the rotating ring 12, a liquid storage tank 14 for storing herbicides is fixedly provided at the top of the extension rod 15, a nozzle 23 for spraying herbicides is installed at the bottom of the extension rod 15, and the liquid storage tank 14 and the nozzle 23 are connected by a hose.

[0047] Furthermore, the bottom end of the extension rod 15 is fixedly connected to a slide rail 22 arranged in the same direction as the extension rod 15, a slide rod 21 is slidably installed on the slide rail 22, a nozzle 23 is fixedly installed at the bottom end of the slide rod 21, and a reciprocating drive mechanism is provided at the free end of the extension rod 15 for driving the slide rod 21 to perform reciprocating motion on the slide rail 22.

[0048] Furthermore, the reciprocating drive mechanism includes a swing rod 18 and a drive assembly, one end of the swing rod 18 is fixedly sleeved with a pin shaft 17, the pin shaft 17 is driven to rotate by the drive assembly, and the other end of the swing rod 18 is fixedly sleeved with a clamping shaft 19;

[0049] A limiting rod 20 fixedly mounted at the bottom end of the sliding rod 21 is provided on the side of the nozzle 23 away from the pole body 1. The limiting rod 20 is arranged perpendicular to the sliding rod 21 and has a limiting groove 201 along the length direction. The clamping shaft 19 is slidably clamped in the limiting groove 201.

[0050] Further, the driving assembly includes a fixed gear ring 10 and a gear 16 meshed with the fixed gear ring 10 and arranged inside the fixed gear ring 10, the gear 16 is fixedly sleeved on the pin 17, and the top of the pin 17 is rotatably connected to the bottom of the free end of the extension rod 15, and the swing rod 18 is spaced apart at the bottom of the gear 16;

[0051] A fixed ring 111 is arranged on the top of the rotating ring 12 and is fixed on the pole body 1. A plurality of bending rods 11 are evenly fixed on the outside of the fixed ring 111 along the circumferential direction. The free ends of the bending rods 11 are bent downward, and the free ends of the bending rods 11 are fixedly connected to the top of the gear ring 10.

[0052] Furthermore, the linkage rod 9 is a retractable telescopic rod, and the linkage rod 9 is retractable and adjustable, and the distance between the nozzle 23 and the ground can be adjusted, so that the spraying position of the nozzle 23 can be flexibly adjusted.

[0053] As can be seen from the above description, the worm gear 8 is driven to rotate to drive the rotating ring 12. During the rotation of the rotating ring 12, the extension rod 15 is driven to make a circular motion around the pole, so that the gear 16 at the free end of the extension rod 15 rotates under the meshing action of the fixed gear ring 10. The gear 16 can synchronously drive the pin shaft 17 to rotate. When the pin shaft 17 rotates, it will drive the swing rod 18 to rotate with the pin shaft 17 as the rotation center. During the rotation process, the free end of the swing rod 18 will be clamped in the limit groove. The clamping shaft 19 pushes the limit rod 20 to move, so during the continuous rotation of the swing rod 18, the clamping shaft 19 continuously drives the sliding rod 21 to reciprocate on the slide rail 22, so that the nozzle 23 reciprocates synchronously. On the premise that the extension rod 15 makes a circular motion around the pole, the nozzle 23 reciprocates along the slide rail 22, so that the nozzle 23 can not only spray the herbicide around the pole, but also expand the spraying range of the nozzle 23 by reciprocating along the slide rail 22.

[0054] The working principle of the present invention is as follows: by arranging the pile top clamp, the electric pole can be passed through the pile top clamp before installing the electric pole, so that it can be effectively centered to prevent the electric pole from being installed tilted, and by fixing the pile top clamp and the steel cage through a connecting rod, the stability of the pile top clamp can be effectively increased, so that the electric pole can be effectively prevented from being tilted, which helps to ensure the stability of the electric pole; at the same time, by arranging the upper support column, the electric pole can be further centered to ensure that the electric pole is vertical, and at the same time the electric pole is tightly sleeved by the upper support column, and the upper support column and the soil are fully combined, so that the settlement of the electric pole can be effectively prevented, and the lower support column is added on the basis of the upper support column, which increases the burial depth of the entire concrete column, further improves the stability of the concrete column, and thus prolongs the service life of the electric pole, improves the stability and safety of the electric pole, effectively solves the problem of settlement and tilt of the electric pole caused by insufficient bearing capacity of the soil, and is beneficial to the normal operation of the transmission line.

[0055] By setting up a spraying mechanism, the driving worm gear can be used to drive the rotating ring. During the rotation of the rotating ring, the extension rod will be driven to make a circular motion around the pole, and then the gear at the free end of the extension rod will rotate under the meshing action of the fixed gear ring. The gear can synchronously drive the pin shaft to rotate. When the pin shaft rotates, it will drive the swing rod to rotate with the pin shaft as the rotation center. During the rotation process, the free end of the swing rod will push the limit rod to move through the clamping shaft arranged in the limit groove. Therefore, during the continuous rotation of the swing rod, the clamping shaft continuously drives the sliding rod to make a reciprocating motion on the slide rail, so that the sprinkler head makes a reciprocating motion synchronously. On the premise that the extension rod makes a circular motion around the pole, The nozzle makes reciprocating motion along the slide rail, so that the nozzle can not only spray the herbicide around the pole, but also expand the spraying range of the nozzle by reciprocating motion along the slide rail, so as to effectively remove the weeds within a certain range near the pole, and thus effectively eliminate the fire hazard around the root of the pole, and prevent small animals from building nests at the root of the pole, so as to ensure the tidiness and cleanliness of the root of the pole, prevent the pole from being eroded, and reduce the work intensity of the weeders. The weeders only need to add the herbicide regularly, and the maintenance personnel can also see the situation around the pole at a glance, and more easily approach the pole to conduct inspections and necessary maintenance work.
