Description

Technical Field

[0001] This invention relates to the field of communication tower technology, and in particular to a fixing device for the bottom of a communication tower. Background Technology

[0002] Communication towers consist of steel components such as the tower body, platform, lightning rod, ladder, and antenna supports, and are treated with hot-dip galvanizing for corrosion protection. They are mainly used for the transmission and transmission of microwave, ultra-short wave, and wireless network signals. In the construction of modern communication and broadcasting signal transmission tower projects, regardless of whether the user chooses a ground-level or rooftop tower, to ensure the normal operation of the radio communication system, the communication antenna must be placed at the highest point to increase the service radius and achieve the desired communication effect. Elevating the antenna requires a steel tower; therefore, steel structure towers play a crucial role in communication systems. Communication towers adopt a four-legged self-supporting structure, conforming to steel structure design specifications.

[0003] The base fixing device is crucial during the installation of communication towers, as it directly determines the tower's stability. Currently, existing fixing devices still have certain shortcomings. Although they serve the purpose of securing the communication tower, when an earthquake occurs around the tower, the connection between the tower and the fixing device can easily break due to vibration, leading to the tower's collapse. Therefore, there is an urgent need to design a new base fixing device for communication towers to solve these problems. Summary of the Invention

Movable grooves are formed at the four corners of the outer wall of the base, and movable blocks are placed in these grooves. Placement grooves are formed on the outer walls of the movable blocks, and the fixing blocks are located within these placement grooves. A first annular groove is formed on the inner wall of the movable groove. An annular plate is provided on the outer wall of the movable block, and the annular plate is located within the first annular groove. A first fixing groove is formed on the bottom inner wall of the movable groove, and an elastic element is provided on the bottom inner wall of the first fixing groove. A locking block is provided at the end of the elastic element, and the locking block is movably disposed in the first fixing groove. A locking groove, which is hemispherical, is formed on the bottom outer wall of the movable block and matches the locking block. The device also includes: A dust-blocking component is disposed on the outer wall of the movable block to prevent dust from entering the movable groove.

[0006] As a further embodiment of the present invention: the dustproof assembly includes a dustproof cover disposed on the outer wall of the movable block, the bottom end of the dustproof cover is provided with a fourth annular groove, the inner wall of the fourth annular groove is provided with an elastic element two, and the end of the elastic element two is provided with a dustproof cylinder, the dustproof cylinder is movably disposed in the fourth annular groove, and the end of the dustproof cylinder is provided with a rubber ring, the outer wall of the base is provided with a third annular groove, and the dustproof cylinder is located in the third annular groove.

[0007] As a further embodiment of the present invention: a fixing plate is fixedly installed in the tower body, and an installation hole is opened on the outer wall of the fixing plate. A first threaded cylinder is fixedly installed in the installation hole, and a screw is threadedly connected to the first threaded cylinder. A second fixing groove is opened on the outer wall of the base, and a second threaded cylinder is fixedly installed in the second fixing groove. The end of the screw is threadedly connected to the inner wall of the second threaded cylinder. The thread direction in the first threaded cylinder is opposite to the thread direction in the second threaded cylinder. The outer wall of the screw is provided with grips that are evenly distributed in a ring.

[0008] As a further embodiment of the present invention: the outer wall of the base is provided with grooves that are equally spaced and staggered, and the inner wall of the groove is provided with insertion holes, into which a rod is inserted, and the end of the rod is provided with a pressure plate, the pressure plate and the inner wall of the groove are fitted together.

[0009] As a further embodiment of the present invention: the outer wall of the movable block is provided with spherical grooves that are evenly spaced and distributed in a ring, and the inner wall of the spherical grooves is provided with limiting openings.

Under the elastic force of the elastic element, the locking block can be locked into the locking groove at the bottom of the movable block, which can limit the position of the movable block and ensure the stability of the communication tower during normal use. When an earthquake occurs near the communication tower, the ground vibration will cause the movable block to shake in the movable groove, causing the movable block to forcefully press down on the locking block and compress the elastic element. This causes the movable block to break out of its stable state and shake back and forth in the movable groove under the limiting action of the ring plate. This can effectively reduce the transmission of ground vibration to the tower body, play a buffering and shock absorption role, and thus effectively improve the seismic strength of the communication tower when it encounters an earthquake. At the same time, it can also ensure the stability of the communication tower during normal use, resulting in better performance. Attached Figure Description

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1 , Figure 2 and Figure 4As shown, an embodiment of the present invention provides a communication tower bottom fixing device, including a base 1 and a tower body 2. The base 1 is embedded in the ground. Fixing blocks 19 are provided at the four corners of the outer wall of the bottom of the tower body 2. Movable grooves 13 are provided at the four corners of the outer wall of the base 1, and movable blocks 14 are placed in the movable grooves 13. Placement grooves are provided on the outer walls of the movable blocks 14, and the fixing blocks 19 are located in the placement grooves. A first annular groove 15 is provided on the inner wall of the movable groove 13, and an annular plate 16 is provided on the outer wall of the movable blocks 14. Furthermore, the annular plate 16 is located in the first annular groove 15, and the bottom inner wall of the movable groove 13 is provided with a first fixed groove 24, and the bottom inner wall of the first fixed groove 24 is provided with an elastic element 25. The specific structure of the elastic element 25 is not limited. In this embodiment, preferably, the elastic element 25 is a spring, and the end of the elastic element 25 is provided with a locking block 26, and the locking block 26 is movably disposed in the first fixed groove 24. The bottom outer wall of the movable block 14 is provided with a locking groove that matches the locking block 26, and the locking groove is hemispherical. It also includes: Dust-blocking component 23 is disposed on the outer wall of movable block 14 to prevent dust from entering movable groove 13.

[0017] The base 1 for fixing the tower body 2 can be pre-embedded at the installation point. Then, the fixing block 19 at the bottom of the tower body 2 can be placed in the placement groove of the movable block 14. Under the elastic force of the elastic element 25, the locking block 26 can be locked into the locking groove at the bottom of the movable block 14, which can limit the position of the movable block 14 and ensure the stability of the communication tower during normal use. When an earthquake occurs near the communication tower, the ground vibration will cause the movable block 14 to shake in the movable groove 13, causing the movable block 14 to forcefully press down the locking block 26 and compress the elastic element 25. This causes the movable block 14 to break out of the stable state and shake back and forth in the movable groove 13 under the limiting action of the ring plate 16. This can effectively reduce the transmission of ground vibration to the tower body 2, play a buffering and shock absorption role, and thus effectively improve the seismic strength of the communication tower when it encounters an earthquake. At the same time, it can also ensure the stability of the communication tower during normal use, resulting in better performance.

[0018] As one embodiment of the present invention, please refer to Figure 3The dustproof assembly 23 includes a dustproof cover 27 disposed on the outer wall of the movable block 14. The bottom end of the dustproof cover 27 is provided with a fourth annular groove 28, and the inner wall of the fourth annular groove 28 is provided with an elastic element 29. The end of the elastic element 29 is provided with a dustproof cylinder 30, which is movably disposed in the fourth annular groove 28. The end of the dustproof cylinder 30 is provided with a rubber ring 31. The outer wall of the base 1 is provided with a third annular groove 22, and the dustproof cylinder 30 is located in the third annular groove 22. Under the elastic force of the elastic element 29, the dustproof cover 27 can abut against the inner wall of the third annular groove 22, which can play a role in blocking dust and effectively prevent dust from entering the movable groove 13 and causing the movable block 14 to jam. The effect of use is better.

[0019] As one embodiment of the present invention, please refer to Figure 1 A fixing plate 3 is fixedly installed in the tower body 2, and the outer wall of the fixing plate 3 has an installation hole. A first threaded cylinder 4 is fixedly installed in the installation hole, and a screw 5 is threadedly connected to the first threaded cylinder 4. A second fixing groove is opened on the outer wall of the base 1, and a second threaded cylinder 7 is fixedly installed in the second fixing groove. The end of the screw 5 is threadedly connected to the inner wall of the second threaded cylinder 7. The thread direction in the first threaded cylinder 4 is opposite to the thread direction in the second threaded cylinder 7. The outer wall of the screw 5 is provided with a ring of equally spaced gripping rods 6. After the tower body 2 is installed, the screw 5 can be rotated by gripping the gripping rods 6, so that the screw 5 continuously enters the first threaded cylinder 4 and the second threaded cylinder 7, which can connect the base 1 and the tower body 2, further improving the stability of the tower body 2. The screw 5 will only break in the event of a strong earthquake, thus avoiding the impact on the shock absorption of the base 1.

[0020] As one embodiment of the present invention, please refer to Figure 1 The outer wall of the base 1 is provided with grooves 8 that are evenly spaced and staggered, and the inner wall of the grooves 8 is provided with insertion holes.

By inserting the insertion rods 10 into the ground in a staggered manner, the stability of the base 1 can be effectively improved, and the use effect is better.

[0021] As one embodiment of the present invention, please refer to Figure 2 and Figure 4The outer wall of the movable block 14 is provided with equidistant, annularly distributed ball grooves, and the inner wall of the ball grooves is provided with limiting openings. A limiting rod 21 is inserted into the limiting openings, and the end of the limiting rod 21 is provided with a ball 20. The ball 20 fits into the ball groove. The outer wall of the fixed block 19 is provided with an inclined groove corresponding to the limiting opening, and the end of the limiting rod 21 is located in the inclined groove. The limiting rod 21 can be inserted into the inclined groove on the outside of the fixed block 19 along the limiting opening, making it difficult for the fixed block 19 to detach from the placement groove of the movable block 14, making the connection between the movable block 14 and the fixed block 19 more stable and improving the performance.

[0022] As one embodiment of the present invention, please refer to Figure 2 and Figure 4 The outer wall of the movable block 14 is provided with second annular grooves 18 that are evenly distributed. The inner wall of the movable groove 13 is provided with limiting plates 17 that are evenly distributed. The limiting plates 17 and the second annular grooves 18 fit together. When the movable block 14 moves in the movable groove 13, the limiting plates 17 can also move in the second annular grooves 18. The cooperation with the ring plate 16 makes the movement of the movable block 14 more stable and the use effect better.

[0023] As one embodiment of the present invention, please refer to Figure 1 At the four corners of the bottom outer wall of the base 1, there are ground stakes 12, and the outer wall of the ground stakes 12 is provided with barbs 11 distributed in a ring at equal intervals. The barbs 11 on the outside of the ground stakes 12 can enhance the grip of the base 1 and make it more effective.

[0024] In use, the base 1 for fixing the tower body 2 can be pre-embedded at the installation point. Then, the fixing block 19 at the bottom of the tower body 2 can be placed in the placement groove of the movable block 14. Under the elastic force of the elastic element 25, the locking block 26 can be locked into the locking groove at the bottom of the movable block 14, which serves to limit the position of the movable block 14 and ensure the stability of the communication tower during normal use. When an earthquake occurs near the communication tower, the ground vibration will cause the movable block 14 to shake in the movable groove 13, causing the movable block 14 to forcefully press down the locking block 26 and compress the elastic element 25. This causes the movable block 14 to break out of its stable state and shake back and forth in the movable groove 13 under the limiting action of the ring plate 16. This can effectively reduce the transmission of ground vibration to the tower body 2, play a buffering and shock absorption role, and thus effectively improve the seismic strength of the communication tower when it encounters an earthquake. At the same time, it can also ensure the stability of the communication tower during normal use, resulting in better performance. Meanwhile, the outer wall of the base 1 A third annular groove 22 is provided, and the dust-blocking cylinder 30 is located in the third annular groove 22. Under the elastic force of the elastic element 29, the dust cover 27 can abut against the inner wall of the third annular groove 22, which can play a role in blocking dust and effectively prevent dust from entering the movable groove 13 and causing the movable block 14 to jam. After the tower body 2 is installed, the screw 5 can be rotated by holding the handle 6, so that the screw 5 continuously enters the first threaded cylinder 4 and the second threaded cylinder 7, which can play a role in connecting the base 1 and the tower body 2, further improving the stability of the tower body 2. The screw 5 will only break when encountering a strong earthquake, avoiding the impact on the shock absorption of the base 1. When the fixed block 19 is placed in the movable block 14, the limiting rod 21 can be inserted into the inclined groove on the outside of the fixed block 19 along the limiting port, making it difficult for the fixed block 19 to detach from the placement groove of the movable block 14, making the connection between the movable block 14 and the fixed block 19 more stable and the use effect better.
