Description

Technical Field

[0001] The present invention relates to the technical field of communication facilities, and in particular to a signal transmission tower. Background Art

[0002] A signal transmission tower is a wireless signal transmission device built by network operators such as China Mobile, China Unicom, and China Telecom. It is called a signal transmission tower because it looks like a tower. It is a public radio station that transmits information between the communication exchange center and mobile phone terminals in a certain radio coverage area.

[0003] Multiple signal transmitters are mounted on the signal transmission tower to achieve signal coverage in multiple directions. When installing a new tower, the installation position of the signal generator needs to be adjusted to obtain the most suitable coverage form. At present, the signal transmitter is mostly fixed directly by a connector, which inevitably leads to a series of installation problems such as inconvenient operation during the installation process, inflexible adjustment, and troublesome precision control. For example, the patent with application number 2013200845047 discloses a signal transmission tower; a vertical pole is provided in the middle of the antenna installation cavity, the vertical pole is connected to a movable component, and the movable component is connected to the antenna body; the antenna body is adjustable in position, but it is extremely limited and it is difficult to cope with the coordination of multiple signal transmitters.

[0004] In addition, during use, the shape of the signal transmission tower makes it easy for birds to nest; especially the rear of the signal generator and other positions, which has some adverse effects on the maintenance, operation, and daily normal operation of the signal transmission tower. As a result, people have designed some bird-repelling structures. For example, the patent with application number 2021208206370 discloses a signal tower with a bird-repelling device, which drives birds away by colliding with a sound-generating mechanism to ensure the normal use of the signal tower. The patent with application number CN2022228167585 discloses a signal tower bird-repelling device, which drives the fan blades to rotate through fast-flowing airflow, drives the bell to make a sound, scares the birds, and prevents birds from staying or nesting at the signal tower for a long time, so as to achieve the effect of bird-repelling. However, they all need to design a bird-repelling structure separately, and they also need to be maintained in later use. In addition, daily rain and snow protection, etc., also need to be solved; in general, a set of structures are designed independently; resulting in too many functional components and interference between them. If multiple functional requirements can be combined and optimized, costs can be reduced and subsequent maintenance work can be facilitated. Summary of the invention

[0046] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0047] Refer to Figure 1-23 , a signal transmission tower, including a tower pole 1, a workbench 2 and a transmitter 3 assembled on the tower pole 1; wherein, the workbench 2 is of an annular structure, providing a safe and reliable standing surface for personnel's tower installation construction, later maintenance operations, etc.; a plurality of transmitters 3 are provided according to the on-site design situation; generally, there are more than three, respectively covering different sectors and overlapping each other.

[0048] It can be understood that the workbench 2 is located at a position close to the top and there is a position for personnel to pass through; moreover, the workbench 2 is located below the transmitter 3, which is more suitable for later maintenance.

[0049] Two layers of azimuth base rings 4 are assembled on the tower pole 1, and the transmitter 3 is assembled on the azimuth base ring 4 through a pitch adjustment member 5.

[0050] Among them, the central axis of the azimuth base ring 4 coincides with the tower pole 1, which is used to cooperate with the adjustment of the horizontal azimuth angle of the transmitter 3; the pitch adjustment member 5 is used to adjust the pitch angle of the transmitter 3; the two cooperate to adjust the transmitter 3 to a suitable angle to provide effective signal coverage.

[0051] It should be noted that in the conventional structural setting, the transmitter 3 is mostly directly fixed on the tower pole 1 through a connecting member; its azimuth and pitch adjustments are relatively troublesome and inconvenient to operate; therefore, in this application, the azimuth base ring 4 and the pitch adjustment member 5 are designed, and the operation will be extremely convenient through this structural design.

[0052] Among them, two layers of azimuth base rings 4 are provided to form at least two connection positions with the pitch adjustment member 5 to ensure the effectiveness and reliability of the structure.

[0053] It should be noted that among the two layers of azimuth base rings 4, the outer diameter of the upper layer is larger than that of the lower layer.

[0054] It can be understood that the height of the transmission tower is very high, and the form of the transmitter 3 is to emit signals obliquely downward; therefore, two layers of azimuth base rings 4 with different outer diameters are designed; through their size difference, the basic downward inclination form can be directly formed, which is more conducive to cooperating with the pitch adjustment member 5.

[0055] Preferably, the azimuth base ring 4 is a tubular ring body; the pitch adjustment member 5 can slide freely on it; after reaching the appropriate azimuth, it is fixed.

[0056] Preferably, the inner side of the azimuth base ring 4 is fixed on the collar 42 that cooperates with the tower pole 1 through a connecting rod 41; by designing the collar 42 and the connecting rod 41, the azimuth base ring 4 can be made into a plurality of fan-shaped assembled bodies during manufacturing; during installation, they are assembled one by one and then assembled.

[0057] Preferably, the collar 42 is directly welded and fixed on the tower pole 1.

[0058] It should be noted that the horizontal accuracy of the azimuth base ring 4 should be maintained.

[0059] Optionally, the lower end of the connecting rod 41 is provided with a diagonal brace connected to the tower pole 1 to improve strength.

[0060] It can be understood that the azimuth base ring 4 can be either a hollow or solid structure; preferably, it is set as a hollow structure with a larger size, which is more convenient for forming a larger contact surface with the connecting structure of the pitching adjustment member 5 and can be more stable and reliable.

[0061] It should be noted that after the azimuth base ring 4 is assembled, the connection positions of the outer ring body should be accurately butted, welded and then polished to ensure the accuracy and smoothness of the outer layer structure.

[0062] In some embodiments, the pitching adjustment member 5 includes: An upper arc sleeve 51 and a lower arc sleeve 52 respectively clamped on the upper and lower layer azimuth base rings 4; An upper connecting member 53 with one end fixedly connected to the upper arc sleeve 51 and the other end hinged to the transmitter 3; A lower connecting rod 54 with both ends respectively hinged to the lower arc sleeve 52 and the sliding seat 55.

[0063] The sliding seat 55 is slidably arranged in the rear end slide rail of the transmitter 3.

[0064] Among them, both the upper arc sleeve 51 and the lower arc sleeve 52 are open sleeves to avoid the connection positions of the connecting rod 41 and the azimuth base ring 4 and can slide freely on the azimuth base ring 4.

[0065] It should be noted that after adjustment in place, a hole is drilled from the upper arc sleeve 51 or the lower arc sleeve 52, passing through the azimuth base ring 4 together, and then a bolt is inserted for position locking; it not only ensures the reliability and effectiveness of position locking but also avoids the structural strength defects of the open sleeve itself.

[0066] During use, first, the upper end of the transmitter 3 is assembled with the upper connecting member 53; at this time, the transmitter 3 can swing; then, the lower connecting rod 54 is assembled to form a basic pitching angle; then, the angle is adjusted by adjusting the position of the sliding seat 55; after adjustment in place, the sliding seat 55 is locked; for example, a pressing bolt is assembled on the outer side of the slide rail or the sliding seat 55 to achieve position locking.

[0067] It should be noted that the upper arc sleeve 51 and the lower arc sleeve 52 can be sleeved from the interface position when assembling the azimuth base ring 4; it can be understood that in order to ensure sliding, the upper arc sleeve 51, the lower arc sleeve 52 and the axis of the azimuth base ring 4 coincide and the dimensions are matched.

[0068] Preferably, the size of the upper arc sleeve 51 is designed to be larger, and two or more hinge positions are formed between the upper connecting member 53 and the transmitter 3, which can further improve the state stability; it should be noted that the central axes of each hinge position need to coincide.

[0069] In some embodiments, the pitch adjusting member 5 further includes: A lead screw 56 connected between the upper arc sleeve 51 and the lower arc sleeve 52; An adjusting sleeve 57 sliding on the lead screw 56 and a nut threadedly connected to the lead screw 56; And a screw tie rod 58 with one end hinged to the adjusting sleeve 57 and the other end hinged to the lower connecting rod 54.

[0070] It should be noted that when adjusting only through the lower connecting rod 54, there will be some inconveniences in operation and the state is not stable; thus, further modifications have been made; in this form, there is no need to lock the sliding seat 55, and only the form of the lower connecting rod 54 needs to be adjusted.

[0071] Specifically, the form of the lower connecting rod 54 can be adjusted by moving the adjusting sleeve 57 or expanding and contracting the screw tie rod 58; preferably, the two are adjusted in combination, which is more convenient.

[0072] It can be understood that the adjusting sleeve 57 slides on the lead screw 56, and its position is locked by the nut; as Figure 9 shown, a nut is respectively arranged at the upper and lower positions of the adjusting sleeve 57; the two nuts clamp to limit the position of the adjusting sleeve 57.

[0073] It should be noted that the lead screw 56 can be pre-welded to the upper arc sleeve 51 and the lower arc sleeve 52 as a whole; or connected during installation; in this case, some connection structures can be designed, such as thread cylinders are arranged below the upper arc sleeve 51 and above the lower arc sleeve 52 to assemble with both ends of the lead screw 56; or, welded on site.

[0074] In some embodiments, a through port is provided at the center position of the workbench 2, and a fence is provided on the outside; after the personnel reach above the workbench 2, operations are carried out.

[0075] As shown in the figure, the workbench 2 includes a support structure below and a mesh plate structure laid above; in order to better ensure the reliability and strength of the structure, an optimized design is carried out on it.

[0076] Specifically, Figures 18 - 23 As shown; a plurality of clamps 21 are pre-welded on the tower pole 1; the clamps 21 are surrounded to form a circle, and gaps are formed between adjacent ones. After the inner end plate of the bottom support 22 is inserted, bolts are passed through to fix it; at the same time, an outer arc ring 23 is assembled at the outermost end of the bottom support 22; a plurality of outer arc rings 23 are assembled into a complete outer ring structure, and the structural strength is reliable.

[0077] In addition, vertical poles are pre-welded on the outer arc ring 23, or holes are reserved for assembling vertical poles on site to form the vertical pole structure of the fence; handrail rings and other structural parts are arranged on the upper ends of the vertical poles to form a complete fence.

[0078] The clamp 21 is a four-sided frame structure, which is welded and fixed on the tower pole 1, and the vertical surfaces on both sides form a cover on both sides of the insertion end of the bottom support 22; it is then fixed with bolts to be more reliable; at the same time, flat plates are fixedly arranged above and below the insertion part of the bottom support 22, which are in contact with the upper and lower end surfaces of the four-sided frame structure of the clamp 21, so that the installation accuracy is better and it is more stable.

[0079] The bottom support 22 is in an arc shape, and its outer end extends upward, which has better force bearing performance; connecting plates are provided at both ends of the outer arc ring 23 and assembled with the outer end of the bottom support 22; Figure 20 As shown, the two sides of the outer end of a bottom support 22 cooperate with two adjacent outer arc rings 23, and the outer arc rings 23 are tightened, so that the structure is reliable.

[0080] The mesh structure laid on the workbench 2 is designed to be assembled and composed of multiple fan-shaped blocks; a support limit block is arranged above the bottom support 22 to match the inner ring side of the mesh structure; the top of the support limit block matches the support surface height of the bottom support 22 to support the mesh structure; at the same time, the inner end of the support limit block is arranged to match the inner end of the mesh structure. Figure 19 As shown, the mesh structure is connected to the bottom support 22 and the outer arc ring 23 by welding or bolting.

[0081] In some embodiments, a protection component 6 is provided at the top of the tower 1; the protection component 6 provides protection for the transmitter 3 against possible natural disasters such as rain, snow, and hail.

[0082] It should be noted that the volume of the protection component 6 should be controlled to ensure that the vertical projection of the protection component 6 covers all the emitters 3 .

[0083] Specifically, as shown in the figure, the protective component includes: a base support body 61, and a plurality of ring nets 62 coaxially arranged above the base support body 61 and rotating; wherein the base support body 61 is composed of a plurality of extending rods arranged around it, and a ring at the outer end, which provides support for the ring net 62 with a small contact surface; in addition, the volume and weight of the ring net 62 should be controlled so that it can rotate smoothly.

[0084] Thus, the multiple ring networks 62 covered by the projection jointly form a top protection form.

[0085] Furthermore, a plurality of blades 63 are arranged above the ring network 62. As Figures 9 - 12 shown, through the arrangement of the blades 63, each ring network 62 can rotate automatically under the action of wind.

[0086] Preferably, the blade 63 forms of each ring network 62 are designed to be inconsistent; thus, the rotation speeds of the respective ring networks 62 are different.

[0087] It should be added that if only protection is required, a fixed net body projection coverage can be set, and that's okay; but there will be some problems in this case; for example, birds build nests above, and the pressure of snow accumulation on it is relatively large, etc., and other structures need to be designed in cooperation; in the solution of this application, optimization design is carried out considering the cooperation and simplification of realizing multiple functions.

[0088] In this application, the fixed net body is designed as multiple coaxial ring networks 62, and it can also rotate; in this way, birds generally won't build nests on it; moreover, when it snows, if there is wind to make the ring network 62 rotate, the accumulation of heavy snow can be reduced.

[0089] In addition, the ring network 62 in a rotating state has a good bird repelling effect; birds basically don't approach.

[0090] In addition, to prevent the ring network 62 from detaching during the rotation process; a pressing and blocking structure is arranged at the top position of the ring network 62; as Figure 18 shown, the pressing and blocking structure is multiple extension rods and reinforcing rings fixed on the tower pole 1.

[0091] In addition, to avoid the influence of continuous windless weather, a power component can also be arranged in cooperation; for example, multiple driving wheels in contact with the bottom surface of the ring network 62 are arranged below the bottom support body 61, and a motor is used to drive the rotation of the ring network 62 when necessary.

[0092] In some embodiments, the lower end of the bottom support body 61 extends outward and is provided with an inclined blocking rod 64, and the lower end of the inclined blocking rod 64 is provided with a bottom ring 65.

[0093] As Figure 18 shown, an outwardly expanding brim form is formed; when snow blocks slide, they are guided to be farther away from the transmitter 3; moreover, by designing the form of the inclined blocking rod 64, the protection area is also enlarged, obtaining a better effect.

[0094] In some embodiments, a pulling rope 66 is arranged between the lower end of the bottom ring 65 and the outer ring of the workbench 2; the pulling ropes 66 are arranged at intervals to form a cage-like protection structure on the side.

[0095] As Figure 10 shown, by controlling the spacing of the draw ropes 66, a reasonable side protection is formed.

[0096] It can be understood that the draw ropes 66 should be made of non-metallic materials to avoid interference and influence on signals.

[0097] Furthermore, ropes can be additionally arranged in the horizontal circumferential direction of the draw ropes 66 to obtain a more stable cage-type protection structure.

[0098] In some embodiments, the tower pole 1 is assembled by splicing multiple tower barrels 11; adjacent tower barrels 11 are assembled through flanges.

[0099] The tower body of the signal tower is generally dozens of meters high, so it needs to be spliced separately; splicing through flanges is a docking form with relatively high precision; however, when performing docking, controlling the position accuracy of the hoisting is relatively troublesome; moreover, generally, several bolts need to be installed first after the foundation is aligned, and the bearing pressure of these bolts is relatively large at the beginning; furthermore, the bolt holes are relatively small, and it is also relatively troublesome and difficult to align the tall tower barrels 11. Therefore, an auxiliary alignment structure is designed.

[0100] Specifically, a guide cylinder 7 is sleeved inside between adjacent tower barrels 11.

[0101] It can be understood that the guide cylinder 7 is inserted into the tower barrel 11; and, it protrudes above the top of the tower barrel 11; as Figure 13 shown, after one tower barrel 11 is in place, a guide cylinder 7 is installed from its top; when hoisting the next tower barrel 11, after basic alignment, the tower barrel 11 can be sleeved on the guide cylinder 7; then, while controlling the hoisting and lowering, the tower barrel 11 is rotated; since there is a guide cylinder 7 inside to limit the position of the tower barrel 11, at this time, it is relatively convenient, very labor-saving, and has high precision to rotate the tower barrel 11 and align the bolt holes.

[0102] Preferably, ring-shaped rings 12 are fixedly arranged at the upper and lower positions inside the tower barrel 11 to cooperate with the guide cylinder 7.

[0103] It can be understood that the ring-shaped ring 12 above the upper part inside the lower tower barrel 11 provides support for the guide cylinder 7; the ring-shaped ring 12 below the lower part inside the upper tower barrel 11 limits the position of the guide cylinder 7; the height of the guide cylinder 7 should be less than the distance between the two ring-shaped rings 12; for better cooperation, preferably, a rubber pad or other structures are arranged on the ring-shaped ring 12 above the upper part inside the lower tower barrel 11 to support the bottom of the guide cylinder 7.

[0104] In some embodiments, a cable centering sleeve 8 is arranged at the upper position inside the tower barrel 11.

[0105] It should be noted that the signal tower is very high, and the cables have a height difference of several tens of meters inside. During the installation process and in daily conditions, the cables shake and are prone to wear and tear on the inner wall. Especially during the initial wiring process, more friction has many adverse effects on the cables. Therefore, the cables are optimized and designed.

[0106] like Figure 14 , 15 As shown, the cable centering sleeve 8 is installed in the tower 11; preferably, the cable centering sleeve 8 is placed on the ring 12 and is pressed by the guide tube 7; not only the installation state is stabilized, but also it serves as the bottom end support of the guide tube 7.

[0107] The cable center sleeve 8 is a flat structure, with the middle part gathering and extending upward and an opening provided therein, forming an inverted bowl-like shape with an opening at the center top; at the same time, an incision is provided on the ring side of the opening, and the opening can be expanded during the upward pulling of the wire.

[0108] Furthermore, a plurality of triangular reinforcement plates are arranged around the outside of the opening; Figure 16 As shown, the downward deformation resistance of the cable centering sleeve 8 is further enhanced by the triangular reinforcement plate.

[0109] It can be understood that the above structure has the characteristics of being easy to expand upwards, but not easy to deform downwards when encountering the force of the cable downward from the center; thus, it not only has a guiding effect, but also can provide a clamping force for the installed cable, reducing the load pressure at the top.

[0110] In some embodiments, a cable centering roller 9 is provided in the guide cylinder 7; it cooperates with the cable centering sleeve 8 to strengthen the adjustment of the cable; and, the cable centering roller 9 is designed in the guide cylinder 7, and there is no need to change the structure of the tower 11; and, it relies on the smaller guide cylinder 7, and the production is also simpler and more convenient.

[0111] Specifically, two cable centering rollers 9 are symmetrically arranged as a group to limit the cable from both sides.

[0112] like Figure 14 , 15 As shown in 17, the cable centering roller 9 is hinged to the guide cylinder 7 through the support arm 91 and swings; in the natural state, the axes of the two cable centering rollers 9 are higher than the hinged position, and the inner ends are in conflict with each other.

[0113] Furthermore, the cable centering roller 9 is provided with multiple layers; and the clamping surfaces of the cable centering rollers 9 of adjacent layers face different directions; Figure 14 As shown, the clamping surfaces of the upper and lower cable centering rollers 9 extend front to back and left to right respectively; thus, the cable can be centered multiple times in multiple directions, achieving better results.

[0114] It can be understood that the tilt angle of the control arm 91 is designed in cooperation with the center of gravity to prevent the cable centering roller 9 from swinging outwards and leaning against the inner wall of the guide cylinder 7 during the upward pulling of the cable. Preferably, an elastic structure is designed to apply a force to the arm 91 so that it continuously swings downward towards the center position.

[0115] Preferably, the middle of the cable centering roller 9 is recessed to form an arc.

[0116] It should be noted that according to the actual cable layout requirements, the shape of the middle recess of the cable centering roller 9 can be designed to better guide it.

[0117] Furthermore, a fixed shaft is integrally designed with the cable centering roller 9. After the fixed shaft penetrates to the outside of the arm 91, a one-way ratchet structure is designed. Thus, when the cable is pulled upward, the cable centering roller 9 can rotate; but when the cable tends to move downward, it cannot rotate; at the same time, relying on the friction between the cable and the cable centering roller 9, the cable is clamped and fixed in the middle, further reducing the load pressure at the top.

[0118] In the present invention, the workbench 2 is optimally designed to provide a safe and reliable standing surface for the tower installation construction and later maintenance operations of personnel; moreover, the installation accuracy is better and it is more stable; the assembly azimuth base ring 4 cooperates with the pitching adjustment member 5 to adjust the transmitter 3 to an appropriate angle to provide effective signal coverage, and the operation is extremely convenient; the protection component 6 is provided to protect the transmitter 3 and can automatically rotate under the action of wind force, realizing the optimal design of multiple functions, having a good bird repelling effect, and also being able to reduce the accumulation of heavy snow; a pull rope 66 is arranged on the outer ring to form a cage-type protection structure on the side; an auxiliary alignment structure is designed to perform basic alignment on the tower barrel 11 and rotate to align the bolt holes, which is very convenient, very labor-saving, and has high accuracy; a cable centering sleeve 8 is provided, which not only stabilizes the installation state but also serves as the bottom support of the guide cylinder 7; a cable centering roller 9 is provided to further strengthen the adjustment of the cable; moreover, it is not necessary to change the structure of the tower barrel 11, and the production is also simpler and more convenient.
