Description

Technical Field

[0001] The invention relates to the technical field of power grid accessories, and in particular to a pole tower protection component for power grid construction. Background Art

[0002] In the construction of power grids, poles and towers, as key infrastructure supporting transmission lines, play a vital role in ensuring stable power transmission. Pole poles are exposed to the natural environment for a long time and face many threats. In severe weather conditions, strong winds, heavy rains, heavy snow, and lightning strikes will impact the tower structure, causing the tower to tilt and collapse, and then cause power outages. Therefore, a power grid construction tower protection component is needed to protect the tower.

[0003] Traditional power grid construction tower protection components mostly use reinforcement and anti-corrosion methods to protect the towers. However, in heavy snow weather, the accumulated snow will be absorbed and frozen on the towers, increasing the weight of the towers, which can easily cause the towers to tilt or collapse. Manual de-icing is a large project, time-consuming and labor-intensive, and can easily cause safety accidents, making it less suitable for use. Summary of the invention

[0004] The purpose of the present invention is to provide a pole tower protection component for power grid construction, so as to solve the defect that the existing pole tower protection components for power grid construction are inconvenient for de-icing the pole tower.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: A pole tower protection component for power grid construction comprises a pole tower body fixed on a foundation;

[0006] The inner side of the tower body is evenly provided with a protective structure, the protective structure includes a connecting seat, a built-in cavity, a guide tube, a spring and a ball. The connecting seat is evenly provided on the inner side of the tower body, the inner side of the connecting seat is provided with a built-in cavity, the inner side of the built-in cavity is provided with a guide tube, the inner sides of the guide tube are provided with springs, and a ball is provided between adjacent springs;

[0007] Connecting rods are fixedly installed at both ends of the connecting seat by bolts, and a fixing structure is hingedly installed on the outer wall of the connecting seat;

[0008] A driving structure is fixedly installed on the inner side of the bottom of the tower body.

[0009] The protective structure can effectively reduce the loss of vibration during the transmission process, assist in enhancing the vibration effect, and facilitate the cleaning of ice and snow attached to the outer wall of the tower. At the same time, the guide tubes of different axes make the movement direction of the sphere different, avoiding resonance of the tower during the knocking vibration process and avoiding damage to the tower during the vibration process.

[0010] Preferably, the fixing structure includes a sleeve rod, a first fixing rod, a hook, a locking nut and a second fixing rod, one end of the second fixing rod is hingedly mounted on the outer wall of the connecting seat, the outer side of the other end of the second fixing rod is threadedly connected to the sleeve rod, the inner side of the sleeve rod away from one end of the second fixing rod is threadedly connected to the first fixing rod, one end of the first fixing rod extends to the outside of the sleeve rod and is threadedly connected to the hook, and the outer wall of the hook close to one end of the first fixing rod is threadedly connected to a locking nut.

[0011] Preferably, a reserved hole is passed through the middle of the sleeve rod, and one end of the first fixing rod abuts against one end of the locking nut. The reserved hole facilitates the sleeve rod to rotate, so that the distance between the first fixing rod and the second fixing rod changes.

[0012] Preferably, one end of the second fixing rod is vertically hinged to the outer side wall of the connection seat, and the second fixing rod has an external thread in the opposite direction to that of the first fixing rod. The vertical hinge enables the second fixing rod to select a tower main body accessory that is higher or lower than the connection seat during installation, so that it is convenient for it to be flexibly hooked and fixed.

[0013] Preferably, the driving structure includes a base, a turntable, a reserved groove, a striking block, a pressure bearing, a transmission gear and a driving motor. The base is fixedly installed on the foundation on the inner side of the bottom of the tower body, a pressure bearing is fixed to the top of the base, a turntable is fixed to the top of the pressure bearing, reserved grooves are evenly opened at the edge positions of the bottom of the turntable, striking blocks are arranged inside the reserved grooves, a transmission gear is arranged at the middle position of the top of the base, a driving motor is fixedly installed on one side below the transmission gear, and a driving gear is fixedly installed on the output end of the driving motor.

[0014] Preferably, the base and the turntable are rotatably connected via a pressure bearing, and the turntable is located on one side of the bottom of the connecting rod.

[0015] Preferably, the striking block is in an arc shape, and one end of the striking block is hinged to the turntable. When the turntable rotates, under the action of centrifugal force, one end of the striking block will move to the outside of the turntable, so that the outer wall of the arc-shaped striking block collides with one end of the connecting rod. During the collision, due to the reaction force, the striking block will move to the inside of the reserved groove, and the impact will be cyclically circulated, thereby avoiding the striking block from breaking and extending the service life of the striking block.

[0016] Preferably, the top end of the transmission gear rotating shaft extends to the outside of the base and is fixedly connected to the bottom end of the turntable, the bottom end of the transmission gear rotating shaft extends to the inside of the base and is rotatably connected to the base, and the driving gear is meshingly connected to the transmission gear.

[0017] Preferably, both ends of the guide tube are fixedly connected to the inner side wall of the connection seat, and the central axis directions of the guide tubes are different. The guide tubes with different axial directions make the movement directions of the sphere different, thus avoiding resonance of the pole tower during the knocking vibration process.

[0018] Preferably, one end of the spring is fixedly connected to the inner side wall of the connecting seat, and the sphere forms an elastic structure inside the guide tube through the spring. The elastic structure can effectively enhance the vibration effect, slow down the energy loss, and enable the top to still clear ice and snow through vibration.

[0019] The invention provides a power grid construction tower protection component, which has the advantages of:

[0020] By providing the protective structure, the central axis directions of the guide tubes are different, so that the moving directions of the ball inside the connection seat are different. Under the elastic force of the spring, the ball exerts impact forces in different directions on the pole tower, causing the pole tower to vibrate, thereby causing ice and snow attached to the outer wall of the pole tower to fall off, realizing the function of the device to facilitate deicing, thereby improving the applicability of the pole tower protective component of the power grid construction when in use;

[0021] Furthermore, the guide tubes with different axial directions make the movement directions of the spheres different, thus avoiding resonance of the pole tower during the knocking vibration process, thereby improving the safety of the device during use;

[0022] Furthermore, the reserved hole facilitates the rotation of the sleeve rod, so that the distance between the first fixing rod and the second fixing rod changes, which is convenient for adjusting the fixed distance. At the same time, the hook and the first fixing rod are threadedly connected to quickly replace the hook, which is convenient for hooking and fixing tower components of different diameters.

[0023] Furthermore, the driving motor drives the turntable to rotate through the driving gear and the transmission gear, so that the striking block is in an open state, and the outer wall of the striking block will collide with the bottom of the connecting rod. Under the transmission of the connecting rod and the connecting seat, the pole tower will vibrate up and down, which is convenient for clearing ice and snow. BRIEF DESCRIPTION OF THE DRAWINGS
