Description

Technical Field

[0001] This utility model relates to the field of power transmission tower technology, and in particular to an adjustable power transmission tower. Background Technology

[0002] Transmission line towers are tower-shaped structures used for power transmission. Their structural characteristics include a space truss structure for all tower types, with members primarily composed of single equilateral angle steel or composite angle steel. Existing transmission towers typically consist of a tower body and crossarms on that body. The crossarms are used for hoisting and laying power transmission lines and are usually fixed to the tower body. During the installation of transmission towers, due to complex installation environments, towers are often installed in mountainous or low-lying areas. This results in significant differences in the horizontal height of the crossarms on adjacent towers, affecting not only the stability of the transmission line installation but also increasing the amount of power required for the transmission circuit.

[0003] For example, in the prior art, patent CN218324192U discloses a height-adjustable high-voltage transmission tower. When the height of the crossarm on the transmission tower needs to be adjusted, the device can activate a synchronous motor to rotate the connecting rod at the output end, thereby rotating a screw. The rotation of the screw causes a moving block on its outer surface to move up and down. As the moving block moves up and down, it adjusts the height of the crossarm via a first connecting block, thus adjusting the height of the overhead line component.

[0004] The device adjusts the tower height by rotating a screw driven by a motor. Each tower is driven by two motors. When the two motors rotate at different speeds, it can affect the adjustment of the tower height and the normal operation of the motors. Furthermore, the motors of this device are directly mounted on the tower body, which is a steel structure. When the tower body is struck by lightning, the motors will be damaged, affecting their service life. Therefore, an adjustable power transmission tower is designed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose an adjustable power transmission and transformation tower.

[0006] The technical problem to be solved by this utility model is to provide an adjustable power transmission and transformation tower, which solves the problem that the height of the tower arm of the existing steel structure tower is fixed and inconvenient to adjust.

[0007] This utility model provides an adjustable power transmission and transformation tower, including a base, a tower body, and a crossarm. The tower body is fixedly installed on the top of the base. Sliding grooves are provided on both the inner and outer sides and the left and right ends of the tower body. A sliding strip is fixedly installed at the connection between the crossarm and the tower body. The sliding strip is slidably installed in the sliding groove. A positioning bolt for positioning the horizontal height of the crossarm is threaded onto the sliding strip. A height adjustment component for driving the crossarm to rise and fall is installed on the top of the tower body.

[0008] Preferably, the groove has multiple bolt holes that match the positioning bolts, which are evenly spaced within it.

[0009] Preferably, the cross-section of the groove is convex, and the shape of the slide bar matches the shape of the groove.

[0010] Preferably, the height adjustment assembly includes a horizontal plate fixed to the top of the tower body and a vertical rod fixed to the top of four sliding bars. An external threaded rod is rotatably provided on the center of the upper surface of the horizontal plate via a bearing. A handle is fixedly provided in the center of the external threaded rod. An internal threaded sleeve is threadedly connected to the external threaded rod. Four connecting plates are fixedly provided on the side of the internal threaded sleeve, and the other end of the connecting plate is fixedly provided on the vertical rod.

[0011] Preferably, the chute is a top-sealed trough structure, and the vertical rod passes through the top seal of the chute.

[0012] Preferably, the length of the handle is 5-10 times the diameter of the external thread rod.

[0013] Preferably, the top of the external threaded rod is pointed with a gradually decreasing diameter, and both the external threaded rod and the cross plate are made of conductive stainless steel, with a grounding wire electrically connected to the ground on the cross plate.

[0014] Compared with the prior art, this utility model has at least the following beneficial effects:

[0015] 1. This utility model is equipped with a height adjustment component. When it is necessary to adjust the horizontal height of the crossarm, the handle is turned, which drives the external threaded rod to rotate. The internal threaded sleeve on the external threaded rod rotates and moves up and down along the external threaded rod. The internal threaded sleeve drives the four vertical rods to move up and down simultaneously through the connecting plate, so as to achieve the effect of adjusting the horizontal height of two crossarms at the same time. The height adjustment is simple, convenient and highly practical.

[0016] 2. This utility model sets the top of the external threaded rod into a pointed shape with a reduced diameter component, so that the external threaded rod can be used as a lightning rod. When the external threaded rod is struck by lightning, it can guide the current to the horizontal plate and transmit it to the ground through the grounding wire, thereby achieving the effect of lightning protection.

[0023] Example: Figures 1-3 As shown, an embodiment of this utility model provides an adjustable power transmission and transformation tower, including a base 1, a tower body 2, and a crossarm 3. The tower body 2 is fixedly installed on the top of the base 1. Sliding grooves 201 are provided on both the inner and outer sides of the tower body 2. A sliding strip 301 is fixedly installed at the connection between the crossarm 3 and the tower body 2. The sliding strip 301 is slidably installed in the sliding groove 201. A positioning bolt 302 for positioning the horizontal height of the crossarm is threaded onto the sliding strip 301. A height adjustment component for driving the crossarm 3 to rise and fall is installed on the top of the tower body 2.

[0024] In this embodiment, the slide groove 201 has multiple bolt holes that match the positioning bolts 302 at equal intervals. The positioning bolts 302 are threaded into the bolt holes to fix the horizontal height of the tower arm.

[0025] In this embodiment, the cross-section of the slide groove 201 is convex, and the shape of the slide bar 301 matches the shape of the slide groove 201, ensuring the stability of the slide bar 301 sliding on the slide groove 201.

[0026] In this embodiment, the height adjustment component includes a horizontal plate 5 fixed to the top of the tower body 2 and a vertical rod 4 fixed to the top of four sliding bars 301. An external threaded rod 6 is rotatably provided on the upper surface of the horizontal plate 5 through a bearing. A handle 601 is fixedly provided in the center of the external threaded rod 6. An internal threaded sleeve 7 is threadedly connected to the external threaded rod 6. Four connecting plates 8 are fixedly provided on the side of the internal threaded sleeve 7, and the other end of the connecting plate 8 is fixedly provided on the vertical rod 4.

[0027] With the height adjustment component, when the horizontal height of the crossarm 3 needs to be adjusted, the handle 601 is turned. The handle 601 drives the external threaded rod 6 to rotate, and the internal threaded sleeve 7 on the external threaded rod 6 rotates up and down along the external threaded rod 6. The internal threaded sleeve 7 drives the four vertical rods 4 to rise and fall simultaneously through the connecting plate 8, so as to achieve the effect of adjusting the horizontal height of the two crossarms 3 at the same time. The height adjustment is simple, convenient and highly practical.

[0028] In this embodiment, the slide 201 is a top-sealed groove structure, and the vertical rod 4 passes through the top seal of the slide 201 to prevent the slide bar 301 from coming out of the upper opening of the slide 201.

[0029] In this embodiment, the length of the handle 601 is 5-10 times the diameter of the external thread rod 6, making it easier to rotate the external thread rod 6 by means of the handle 601.

[0030] In this embodiment, the top of the external thread rod 6 is pointed with a gradually decreasing diameter, and both the external thread rod 6 and the horizontal plate 5 are made of conductive stainless steel. The horizontal plate 5 is electrically connected to a grounding wire connected to the ground.

[0031] By setting the top of the external threaded rod 6 into a pointed shape with a reduced diameter component, the external threaded rod 6 can be used as a lightning rod. When the external threaded rod 6 is struck by lightning, it can guide the current to the horizontal plate 5 and transmit it to the ground through the grounding wire, thus achieving the effect of lightning protection.

[0032] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
