Description

TUBE TOWER AND BASE STATION [0001] The present application claims priority to Chinese Patent Application No. 201720511089.7, entitled Towers and Base Stations, filed on May 10, 2017, the entire contents of which are hereby incorporated by reference in its entirety.

TECHNICAL FIELD [0001] This disclosure relates to the field of communications device installation technologies, and in particular, to a tube tower and a base station.

BACKGROUND [0002] Development of mobile communication services is accompanied with a requirement for a large quantity of communications sites. For various reasons, a conventional site with a relatively large floor area is very difficult to obtain. Therefore, base station device suppliers are devoted to a base station design with a reduced floor area. A current popular base station design solution with a reduced floor area is integrating a base station into a tower, that is, installing a base station device inside a tubular tower, so as to significantly reduce a floor area.

[0003] To achieve the objective of installing a base station device inside, a rectangular opening usually needs to be disposed in a tower body of a tube tower. A tube-tower-type base station in the prior art is shown in FIG. 1, and includes a tube tower 101 and an antenna 102. A rectangular opening 103 is disposed in a tower body 104 of the tube tower 101.

[0004] The prior art has at least the following problem:

[0005] Because a large rectangular opening is disposed in the tower body, tower body gravity above the opening cannot be well supported, and stress is concentrated near the opening. Consequently, structural strength of the tube tower is reduced, and the tube tower is likely to be deformed.

SUMMARY [0006] In view of this, embodiments of this disclosure provide a tube tower and a base station, to improve structural strength of a tube tower whose tower body has a relatively large opening. The technical solutions of the embodiments of this disclosure are as follows:

[0007] According to a first aspect, a tube tower is provided, where the tube tower includes a tower base and a tower body fastened on the tower base, an opening is disposed in the tower body, and the opening is configured to allow a device to be installed inside the tube tower through the opening; and the tube tower further includes an auxiliary support structure disposed inside the tower body, the auxiliary support structure includes at least two support plates that are supported on the tower base or supported in the tower body, a vault is disposed on the top of the at least two support plates, and an upper edge of the opening abuts against the vault and/or the vault is connected to an inner side of the tower body to provide support for the upper edge of the opening.

[0008] In this embodiment of this disclosure, the opening that is large enough to allow a device to pass through is disposed in the tower body of the tube tower, and the auxiliary support structure disposed inside the tower body is configured to provide auxiliary support. The auxiliary support structure includes the at least two support plates fastened on the tower base and the vault disposed on the top of the support plates. Because the upper edge of the opening abuts against the vault and/or the vault is connected to the inner side of the tower body to provide support for the upper edge of the opening, pressure caused by tube tower gravity above the opening is transferred to the support plates by using the vault. In the prior art, pressure above an opening is borne by parts of a tower body near both sides of the opening. Therefore, stress is concentrated, and consequently structural strength of a tube tower is reduced, and the tube tower is likely to be deformed and damaged. However, in this embodiment of this disclosure, the upper edge of the opening of the tube tower is supported by the vault, and a relatively stable support structure is formed, and therefore structural strength of the tube tower is greatly improved.

[0009] In a first possible implementation of the first aspect, the at least two support plates are connected to the inner side of the tower body by means of fastening.

[0010] In this way, because the support plates are connected to the inner side of the tower body by means of fastening, the support plates are integrated into the tower body, and the tower body is more stable.

[0011] Alternatively, two vertical sides of each support plate are separately connected to the inner side of the tower body by means of fastening.

[0012] In this way, each support plate and a corresponding part of the tower body form a closed cavity, and a horizontal cross section of the cavity is similar to a triangle. This improves support strength and overall rigidity of the tube tower.

[0013] In a second possible implementation of the first aspect, a smooth transition structure is formed in at least one of a transition place between the upper edge and a vertical edge of the opening, a transition place between a lower edge and a vertical edge of the opening, or a transition place between the vault and the support plate.

[0014] In this way, when a smooth transition structure is used in the transition place between the upper edge and the vertical edge of the opening, stress concentration can be effectively avoided, thereby avoiding a prior-art problem that stress is concentrated because a right angle is used at an upper part of an opening of a tube tower, and consequently structure deformation and damage are likely to be caused. When a smooth transition structure is used in the transition place between the lower edge and the vertical edge of the opening, stress concentration can be effectively avoided, thereby avoiding a prior-art problem that stress is concentrated because a right angle is used at a lower part of the opening of the tube tower, and consequently structure deformation and damage are likely to be caused. When a smooth transition structure is used in the transition place between the vault and the support plate, stress concentration can be effectively reduced, thereby avoiding a problem that a support structure of the vault is deformed and damaged.

[0015] In a third possible implementation of the first aspect, the vault is a circular-arc vault, and the upper edge of the opening fits with the circular-arc vault.

[0016] In this way, the vault and the upper edge of the opening closely fit because of corresponding outlines. Therefore, pressure is transferred to the vault in a deconcentrated manner, so that a support structure of the vault is optimized, and the vault is prevented from being damaged due to excessive partial pressure.

[0017] In a fourth possible implementation of the first aspect, the vault includes a plurality of sequentially-adjacent flat-plate parts, and angles formed between the adjacent flat-plate parts are all obtuse angles.

[0018] In this way, the vault can be formed by bending a plate several times, and therefore is easily manufactured. In addition, compared with direct angles and acute angles, the obtuse angles do not cause excessive stress at comers.

[0019] In a fifth possible implementation of the first aspect, a front end of the vault exceeds the upper edge of the opening in a direction towards an exterior of the tube tower.

[0020] In this way, an abutment place of the upper edge of the opening is farther away from an end part of the vault, and therefore the vault more firmly supports the upper edge of the opening.

[0021] In a sixth possible implementation of the first aspect, the tube tower further includes at least two horizontal plates, the at least two horizontal plates each are horizontally fastened between the at least two support plates, and adjacent horizontal plates are separated at a specific distance in the vertical direction.

[0022] In this way, a plurality of device compartments are obtained after the tube tower is vertically separated by the horizontal plates, and may store various devices. In addition, the existence of the horizontal plates also improves stmctural strength of the auxiliary support stmcture and that of the tube tower.

[0023] Alternatively, an upwardly-extended support piece is disposed on an uppermost horizontal plate, and the support piece supports the vault from below.

[0024] In this way, the support piece on the uppermost horizontal plate provides support for the vault, and this improves support strength of the vault.

[0025] In a seventh possible implementation of the first aspect, due to the opening, at least one-third of a perimeter is missing from a horizontal cross section of the tower body at a maximum horizontal width of the opening.

[0026] In this way, the opening on the tube tower is large enough to allow a larger-size device to be installed inside the tube tower. In addition, after the auxiliary support stmcture in this disclosure is used, stmctural strength of the tube tower can be ensured even though the opening of the tube tower is large.

[0027] According to a second aspect, a base station is provided, and includes the tube tower in the first aspect and an antenna disposed above the tube tower.

[0028] In this embodiment of this disclosure, because the base station uses the tube tower in the first aspect, an opening that is large enough to allow a device to pass through is disposed in a tower body of the tube tower, and an auxiliary support stmcture disposed inside the tower body is configured to provide auxiliary support.

The auxiliary support structure includes at least two support plates fastened on a tower base and a vault disposed on the top of the support plates. Because an upper edge of the opening abuts against the vault and/or the vault is connected to an inner side of the tower body to provide support for the upper edge of the opening, pressure caused by tube tower gravity above the opening is transferred to the support plates by using the vault. In the prior art, pressure above an opening is borne by parts of a tower body near both sides of the opening. Therefore, stress is concentrated, and consequently a tube tower is likely to be deformed and damaged. However, in this embodiment of this disclosure, the upper edge of the opening is supported by the vault, and a relatively stable support structure is formed, and therefore structural strength of the tube tower and that of the base station are greatly improved. In addition, when the tube tower has the foregoing features, the base station may also have the foregoing various advantages correspondingly brought by the foregoing features.

DESCRIPTION OF EMBODIMENTS [0044] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following further describes the implementations of this disclosure in detail with reference to the accompanying drawings.

[0045] A person skilled in the art should understand the following:

[0046] The tube tower in this disclosure is generally but is not limited to a tube tower structure used in a tube-tower-type base station to accommodate a device inside. Alternatively, the tube tower may be a tube tower structure used in another scenario to accommodate a device inside. The tube tower in this disclosure is installed upright or approximately upright. The so-called expressions such as up, down, height, vertical, and horizontal are all based on an upright state of the tube tower after installation. In this disclosure, the description that something is in an upper part or a lower part of an object means that the thing is in a position of an upper-half part or a lower-half part of the object. In this disclosure, the description that something is above or below an object means that the thing is in a position that is outside the object and correspondingly above or below the object. The expressions such as front, rear, left, and right described in this disclosure are described with reference to states shown in the accompanying drawings or may be directions that can be sensed by a person skilled in the art. However, the directions are not strictly limited provided that the directions are substantially correct. In this disclosure, corresponding means cooperation between corresponding objects in jointly implementing a function or a position correspondence between corresponding objects. A person skilled in the art may determine the meaning of corresponding according to a scenario.

[0047] FIG. 2a is a schematic diagram of a three-dimensional structure of a tube tower from two different angles of view according to an embodiment of this disclosure. FIG. 2b is a schematic diagram of a breakdown structure of the tube tower. FIG. 2c is a schematic diagram of a side-view structure of the tube tower. FIG. 2d is a schematic diagram of a main-view structure of the tube tower. As shown in FIG. 2a to FIG. 2c, the tube tower includes a tower base 201 and a tower body 202 fastened on the tower base 201.

[0048] The tower base 201 is configured to fasten the tower body 202, so that the tube tower can be entirely fastened on the ground or another plane. As shown in FIG. 2a and FIG. 2b, the tower base is generally presented as an approximate-disc structure, and through holes are provided on the tower base to fasten fasteners on the ground or to another apparatus through these through holes. However, the tower base in this disclosure is not limited thereto. The tower base may be any other suitable structure. In this embodiment, the tower base 201 and the tower body 202 are disposed separately. However, in some other embodiments, the tower base and the tower body may be integrally formed and cannot be separated.

[0049] The tower body 202 is presented as a tubular structure, a horizontal cross section (there is no opening at a height corresponding to the horizontal cross section) of the tower body may be circular, or may be polygonal or another suitable shape. An opening 203 is disposed in the tower body 202. The opening 203 is configured to allow a device to be installed inside the tube tower through the opening, and therefore the opening is a large opening (compared with a heat dissipation opening or the like). The opening 203 is generally strip-shaped, extends a relatively long distance in a height direction of the tower body 202, and also has an enough width in a horizontal direction, so as to facilitate placement and withdrawing of the device. Herein, allowing a device to pass though does not mean allowing any device to pass through, but means allowing devices that need to pass though the opening according to a previous design, to pass through. It should be understood that, for brevity, an overall structure of the tube tower is not shown in the figure. Actually, the tube tower may be further upwardly extended, and an upper structure may be integrally formed with the structure shown in the figure or form a segment structure. A door may be further disposed at the opening 203 according to a requirement. These all fall within the scope of this disclosure.

[0050] As shown in FIG. 2c, the tube tower further includes an auxiliary support structure 204 disposed inside the tower body. In this embodiment, the auxiliary support structure 204 includes two support plates 205. In another embodiment, the auxiliary support structure 204 may include more than two support plates 205. It should be understood that disposition of the support plates 205 should not affect installation of the device, that is, the support plates 205 generally should not block the opening 203. A vault 206 is disposed on the top of the two support plates 205. The vault 206 and the two support plates 205 may be integrally formed or connected by using a suitable connection structure. As shown in FIG 2b, the two support plates 205 are supported on the tower base 201. The two support plates may be connected to the tower base 201 by using a suitable connection structure by means of fastening, for example, inserted into grooves disposed on the tower base 201; or may not be connected to the tower base 201 by means of fastening. The tower base 201 provides vertical support for the support plates 205 in both the two cases. It should be understood that the support plates provide support in a vertical direction, but the support plates are not necessarily in a strict vertical state, but may be in a suitable state such as an inclined state or a slightly-bent state.

[0051] In some other embodiments, the support plates may be provided with support by the tower body. For example, a protruding structure is extended inwards from inner walls of the tower body, and the support plates are supported by the protruding structure; or the support plates are fastened in the tower body, and the tower body provides support in the vertical direction because of the fastening connection.

[0052] It can be seen from a cross section diagram of the tube tower shown in FIG. 2e and an enlarged diagram shown in FIG. 2f that, an upper edge 209 of the opening 203 abuts against the vault 206, and therefore the vault 206 provides support for the upper edge 209 of the opening 203. The upper edge 209 of the opening 203 may transfer pressure to the vault 206, and the vault 206 transfers the pressure to the two support plates 205, so as to share the pressure bome at the upper edge 209 of the opening 203. The upper edge 209 of the opening 203 and the vault 206 may be in a removable connection, or may be integrally fastened by means of welding or the like.

[0053] In this embodiment, an abutment part between the upper edge 209 of the opening 203 and the vault 206 may be in a center area or an off-center area of the upper edge 209, or in a plurality of non-contiguous areas. This may be determined depending on shapes of the upper edge 209 of the opening 203 and the vault 206.

[0054] In this embodiment, the opening 203 that is large enough to allow a device to pass through is disposed in the tower body 202 of the tube tower, and the auxiliary support structure 204 disposed inside the tower body 202 is configured to provide auxiliary support. The auxiliary support structure 204 includes the two support plates 205 supported on the tower base 201 and the vault 206 disposed on the top of the support plates 204. Because the upper edge 209 of the opening 203 abuts against the vault 206, pressure caused by tube tower gravity above the opening 203 (gravity of a tower body, an antenna, and another structure above the opening) is transferred to the support plates 204 by using the vault 206.

[0055] A tube tower in the prior art is shown in FIG. lc. A tower body 104 is installed on a tower base 105 without an auxiliary support structure or a support plate. Pressure caused by gravity above an opening 103 is entirely borne by the tower body 104, and a part of the tower body 104 near the opening 103 bears great stress. Consequently, structural strength of the tube tower is reduced, and the tube tower is likely to be deformed and damaged. However, in this embodiment, the upper edge 209 of the opening 203 is supported by the vault 206, and a relatively stable support structure is formed, and therefore structural strength of the tube tower is greatly improved.

[0056] In some other embodiments, the upper edge of the opening may not need to abut against the vault. Instead, the vault is connected to an inner side of the tower body to provide support for the upper edge of the opening. For example, the vault is connected to an inner side of a part of the tower body near the upper edge of the opening, a connection place on the inner side of the part of the tower body may be above the upper edge, or on a left or right side or a relative side of the upper edge, or in another suitable position, and a corresponding part of the vault is connected to the connection place on the inner side of the part of the tower body, provided that a specific extent of support can be provided for the upper edge of the opening. The connection may be implemented by means of welding or the like. Obviously, in this case, because the specific extent of support is provided for the upper edge of the opening, pressure can also be transferred to the support plates by using the vault, and a relatively stable support structure is formed, and therefore structural strength of the tube tower is improved. It should be understood that in some other embodiments, when the upper edge of the opening is disposed to abut against the vault, the vault may also be disposed to be connected to the inner side of the tower body.

[0057] In this embodiment, the two support plates 205 may be connected to the inner side of the tower body 202 by means of fastening. This may be implemented by means of welding or by using another suitable connection structure. Because the support plates 205 are connected to the inner side of the tower body 202 by means of fastening, the support plates 205 are integrated into the tower body 202, and therefore the tower body 202 is more stable.

[0058] Specifically, in this embodiment, referring to a cross section diagram of the tube tower shown in FIG. 2g, two vertical edges of each support plate 205 may be separately connected to the inner side of the tower body 202 by means of fastening. For example, the connection is implemented by means of welding. In this way, each support plate 205 and a corresponding part of the tower body 202 form a closed cavity, and a horizontal cross section of the cavity is similar to a triangle. This improves support strength and overall rigidity of the tube tower.

[0059] In the prior art, as shown in FIG. lc, right angles are formed at all edge parts at an upper part and a lower part of the opening 103 in the tower body. Greater stress is borne at a right angle than elsewhere, and stress concentration is likely to form. Consequently, structural strength of the right angle is reduced, and therefore the right angle is damaged.

[0060] This embodiment makes an improvement in view of such defect in the io prior art. As shown in FIG. 2b, a smooth transition structure is formed at a transition place between the upper edge 209 and a vertical edge 210 of the opening 203, that is, the transition place is presented as an arc surface without a comer angle, so that there is no stress concentration point at the transition place. This avoids a prior-art problem that stress is concentrated because a right angle is used at the upper part of the opening of the tube tower, and consequently structure deformation and damage are likely to be caused. In this disclosure, the transition place is generally a surface area near a connection place between two adjacent entities.

[0061] In this embodiment, as shown in FIG. 2b, a smooth transition stmcture may also be formed at a transition place between a lower edge 211 and the vertical edge 210 of the opening 203. In this way, because the smooth transition stmcture is used at the transition place between the lower edge 211 and the vertical edge 210 of the opening 203, a prior-art problem that stress is concentrated because a right angle is used at the lower part of the opening of the tube tower, and consequently stmcture deformation and damage are likely to be caused is avoided.

[0062] It should be understood that in this disclosure, an edge of the opening is generally an area that is between an inner wall and an outer wall and that is adjacent to the opening in the tower body and limits the opening. The vertical edge of the opening is generally an opening edge part mainly extended in the vertical direction (but a case in which the opening edge part also changes to a specific extent in the horizontal direction is not excluded). An edge part above the vertical edge is the upper edge and an edge part below the vertical edge is the lower edge.

[0063] As shown in FIG. 2h, the vault 203 in this embodiment may be a circular-arc vault, that is, projection of the vault in a main view is presented as a circular-arc shape. It should be understood that in this disclosure, the main-view projection of the circular-arc vault 203 is not limited to the circular-arc shape, and may also be presented as another suitable arc shape. These all fall within the scope of this disclosure. In this case, the upper edge 209 of the opening 203 fits with the vault 206, that is, the vault 206 and the upper edge 209 of the opening 203 closely fit because of corresponding outlines. Therefore, pressure is relatively evenly transferred to the vault 206 in a deconcentrated manner, so that a support stmcture of the vault 206 is optimized, and the vault 206 is prevented from being damaged due to excessive partial pressure.

[0064] Referring to FIG. 2e and 2f, a front end of the vault 206 exceeds the upper edge 209 of the opening 203 in a direction towards an exterior of the tube tower. In this way, the abutment place of the upper edge 209 of the opening 203 is farther away from an edge of an end part of the vault 206, and therefore the vault 206 more firmly supports the upper edge 209 of the opening 203.

[0065] It can also be seen from FIG. 2e and FIG. 2f that, in this embodiment, a highest place of the vault 206 may be relatively wide, and a connection place between the vault 206 and the support plate 205 may be relatively narrow. In this case, a smooth transition structure may also be used for transition, so as to avoid a stress concentration point and prevent a support structure of the vault from being deformed and damaged.

[0066] As shown in FIG. 2a and FIG. 2b, the tube tower further includes a plurality of horizontal plates 207. The plurality of horizontal plates 207 each are horizontally fastened between the two support plates 205, and are sequentially separated at specific distances in the vertical direction. A suitable connection structure may be disposed for the support plates 205 to fasten the horizontal plates 207. The distances may be set according to respective actual requirements, and do not need to be equal to each other. Therefore, device compartments 208 in various heights are formed, to arrange corresponding devices. In this way, a plurality of device compartments 208 are obtained after the tube tower is vertically separated by the horizontal plates, and may store various devices. In addition, the horizontal plates 207 also improve structural strength of the auxiliary support structure 204 and that of the tube tower. The horizontal plate in this disclosure is generally a plate-shaped structure in which a plate surface is in a horizontal or substantially horizontal state after the tube tower is installed upright, but the plate surface of the horizontal plate is not limited to being in an absolute horizontal and smooth state. The tube tower in the prior art is shown in FIG. lb, a plurality of horizontal plates 106 are directly disposed inside the tower body 104. Compared with that the horizontal plates 106 are fastened between the support plates 205 in this disclosure, disposition is not flexible enough because the tower body 104 is in a fixed size.

[0067] In this embodiment, an upwardly-extended support piece (not shown in the figure) is disposed on an uppermost horizontal plate in the plurality of horizontal plates 207, and the support piece supports the vault 206. Because being supported by the support piece, the support structure of the vault 206 is more stable and reliable, and structural strength of the tube tower is ensured.

[0068] In this embodiment, due to existence of the opening 203, at least one-third, for example, up to 40%, of a perimeter may be missing from a horizontal cross section of the tower body 202 at a maximum horizontal width of the opening 203. The opening 203 on the tube tower is large enough to allow a larger-size device to be installed inside the tube tower. In addition, after the auxiliary support structure 204 in this disclosure is used, structural strength of the tube tower can be ensured even though the opening 203 of the tube tower is large. However, it should be understood that an opening width may be set according to an actual requirement. Even if the opening is relatively narrow, it also falls within the scope of this disclosure.

[0069] A variant embodiment of this disclosure further provides a tube tower. As shown in FIG. 3, the tube tower is the same as a basic structure of the tube tower in the foregoing embodiment, and a difference is as follows: Disposition of a plurality of flat-plate parts instead of disposition of a circular-arc vault is used for a vault 306. The vault of the tube tower includes three sequentially-adjacent flat-plate parts (presented as three straight line segments in FIG. 3), and angles formed between the adjacent flat-plate parts are all obtuse angles. It should be understood that there may be more than three flat-plate parts. In this way, the vault 306 can be formed by bending a plate several times, and therefore is easily manufactured. In addition, compared with direct angles and acute angles, the obtuse angles do not cause excessive stress at corners.

[0070] It should be understood that in some other embodiments, the vault may have only one flat-plate part, and an upper edge of an opening is in one horizontal cross section and therefore directly abuts against the flat-plate part; or the vault may be a hyperbolic structure or another suitable structure. These also all fall within the scope of this disclosure.

[0071] FIG. 4 shows a base station provided in another embodiment of this disclosure. The base station includes a tube tower 401 provided in the foregoing embodiment and an antenna 402 disposed above the tube tower 401. A person skilled in the art should understand that as a base station, although not shown in the figure, a power supply line, a signal line, and a functional device may be further disposed inside the tube tower 401.

[0072] In this embodiment, because the base station uses the tube tower in the foregoing embodiment, an opening that is large enough to allow a device to pass through is disposed in a tower body of the tube tower, and an auxiliary support structure disposed inside the tower body is configured to provide auxiliary support. The auxiliary support structure includes at least two support plates fastened on a tower base and a vault disposed on the top of the support plates. Because an upper edge of the opening abuts against the vault and/or the vault is connected to an inner 5 side of the tower body to provide support for the upper edge of the opening, pressure caused by tube tower gravity above the opening is transferred to the support plates by using the vault. In the prior art, tower body pressure above an opening is borne by parts of a tower body near both sides of the opening. Therefore, stress is concentrated, and consequently structural strength of a tube tower is reduced, and the tube tower is 10 likely to be deformed and damaged. However, in this embodiment, the upper edge of the opening is supported by the vault, and a relatively stable support structure is formed, and therefore structural strength of the tube tower and that of the base station are greatly improved. In addition, when the tube tower has the foregoing features in the foregoing embodiment, the base station also has the foregoing various advantages 15 correspondingly brought by the foregoing features.

[0073] The foregoing descriptions are merely alternative embodiments of this disclosure, but are not intended to limit this disclosure. Any modification, equivalent replacement, or improvement made without departing from the spirit and principle of this disclosure should fall within the protection scope of this disclosure.
