Description

Technical Field

[0001] This invention belongs to the technical field of signal tower-related accessories, and specifically relates to a signal tower. Background Technology

[0002] A signal tower is a wireless signal transmitting device, named for its tower-like shape. It's also a type of public radio station, referring to a radio transceiver station that transmits information between a communication exchange center and a mobile phone terminal within a defined radio coverage area. Signal towers are commonly used in artificial intelligence for human-machine interaction and communication.

[0003] Currently, the installation of signal towers mostly requires first fixing the base of the signal tower to the ground, usually by pouring concrete, and then fixing the tower pole to the signal tower with bolts.

[0004] However, due to external environmental influences, signal towers are prone to swaying, and over time, this can cause the tower to tilt. The primary reason for this is that prolonged swaying loosens the fixing screws between the base and the tower, causing the tower to shift relative to the base and thus tilt. However, most current signal tower systems cannot detect the connection between the tower and the base, making it impossible to determine the tower's verticality based on inspection results. Summary of the Invention

[0005] The purpose of this invention is to at least solve the problem that existing signal towers cannot detect the connection between the tower pole and the base. This purpose is achieved through the following technical solution:

[0006] This invention proposes a signal tower, which has a tower pole and a base, the base comprising:

[0007] Embedding plate;

[0008] Pressure plates, which are spaced apart above the embedding plate;

[0009] A fixing component is provided on the embedding plate, and the tower is installed on the fixing component. The tower presses against the pressure plate and causes the pressure plate to move down to press against the embedding plate.

[0010] Several detection components are provided, which are used to detect the distance between each detection point on the contact surface of the tower rod and the upper surface of the pressure plate when the tower rod and the pressure plate are pressed together.

[0011] The signal tower of this invention includes a base and a tower pole. The base includes a mounting plate, a pressure plate, a fixing assembly, and several detection components. By setting up the mounting plate, fixing assembly, and tower pole, relative fixation between the tower pole and the mounting plate can be achieved. Furthermore, the pressure plate, positioned between the tower pole and the mounting plate, can press and fix the tower pole to the upper surface of the mounting plate during installation, further ensuring the stability of the base and tower pole.

[0012] Furthermore, by setting up several detection components in conjunction with the tower rod pressing against the pressure plate, the distance between each detection point on the contact surface of the tower rod and the upper surface of the pressure plate can be detected, thereby determining the fixing effect between the tower rod and the base, and further confirming whether the tower rod is in a vertical state.

[0013] This allows for the determination of whether the tower has deflected relative to the mounting plate, thus addressing the issue that signal towers lack the ability to detect whether the tower is vertical.

[0014] In addition, the signal tower according to the present invention may also have the following additional technical features:

[0015] In some embodiments of the present invention, the fixing component includes:

[0016] A positioning plate, which is positioned above the pressure plate;

[0017] A connector is used to fix the positioning disk to the embedding disk;

[0018] Fasteners are used to securely connect the mounting ring of the tower to the positioning plate.

[0019] In some embodiments of the present invention, a conical sleeve is provided on the tower, and a conical groove coupled to the conical sleeve is provided on the positioning plate.

[0020] In some embodiments of the present invention, the detection component includes:

[0021] A pull wire is provided, one end of which is fixed to the upper surface of the pressure plate. The tower rod presses against the pressure plate and partially presses the pull wire into the receiving groove of the pressure plate. The detection point is the connection between the pull wire and the edge of the contact surface.

[0022] A movable component is slidably disposed on the positioning plate. The movable component is connected to the other end of the pull line. The movable component moves downward as the pressure plate moves downward under the action of the pull line.

[0023] A detection element, which is disposed on the positioning disk, is used to detect the downward movement distance of the movable element.

[0024] In some embodiments of the present invention, the detection component further includes:

[0025] A fixing plate is disposed in the pull-out groove of the positioning plate;

[0026] An elastic element is disposed between the fixed plate and the movable element, and the elastic element has a compressed state that causes the movable element to move upward.

[0027] In some embodiments of the present invention, the base further includes:

[0028] A plurality of wing plates are disposed on the embedment plate, and the plurality of wing plates have a transport state in which they are retracted into the interior of the embedment plate, and a working state in which they extend out of the interior of the embedment plate.

[0029] A drive assembly is disposed on the embedding plate and is connected to the plurality of wing plates in a transmission manner, thereby driving the plurality of wing plates to switch between the transport state and the working state.

[0030] The pressure plate presses against the embedded plate to keep the drive assembly driving the wing plate.

[0031] In some embodiments of the present invention, the driving component includes:

[0032] An operating unit is disposed above the embedding plate;

[0033] A rotating component is disposed inside the embedding disc and fixedly connected to the operating part. The operating part can drive the rotating component to rotate relative to the embedding disc, so that the plurality of wing plates retract or extend.

[0034] In some embodiments of the present invention, the plurality of wing plates are arranged at circumferential intervals along the rotating member, and the sidewall of the embedded disk is provided with perforations for the wing plates to retract or protrude.

[0035] In some embodiments of the present invention, the rotating component is provided with a plurality of arc-shaped guide grooves, the arc-shaped guide grooves being provided one-to-one with the wing plate, the wing plate being provided with a sliding column, the sliding column being slidably disposed in the arc-shaped guide groove, the arc-shaped guide groove being able to guide the sliding column to slide along its opening direction, so that the wing plate retracts or extends.

[0036] In some embodiments of the present invention, the operating part is provided with an insertion hole, and the pressure plate is constructed with a limiting post. The limiting post protrudes into the insertion hole as the pressure plate moves downward, so that the rotating member maintains its driving force on the wing plate. Attached Figure Description

Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0056] This invention relates to a signal tower, which, in its overall design, comprises a tower pole and a base. The base includes a mounting plate, a pressure plate, a fixing assembly, and several detection components.

[0057] The pressure plate is positioned above the embedding plate. A fixing assembly is installed on the embedding plate, and the tower is mounted on the fixing assembly. The tower presses against the pressure plate, causing the pressure plate to move downwards and press against the embedding plate. A detection assembly is used to detect the distance between each detection point on the contact surface of the tower and the upper surface of the pressure plate when the tower and pressure plate are pressed together.

[0058] The signal tower of the present invention includes a base and a tower pole, wherein the base includes a mounting plate, a pressure plate, a fixing component, and several detection components. By setting up the mounting plate, the fixing component, and the tower pole, the tower pole and the mounting plate can be relatively fixed. At the same time, the pressure plate set between the tower pole and the mounting plate can press and fix the pressure plate against the upper surface of the mounting plate when the tower pole is fixedly installed, which helps to further ensure the fixing effect of the base and the tower pole.

[0059] Furthermore, by setting up several detection components in conjunction with the tower rod pressing against the pressure plate, the distance between each detection point on the contact surface of the tower rod and the upper surface of the pressure plate can be detected, thereby determining the fixing effect between the tower rod and the base, and further confirming whether the tower rod is in a vertical state.

[0060] Based on the above design concept, an exemplary structure of the signal tower involved in this embodiment is as follows: Figure 1 and Figure 2As shown, the aforementioned embedding plate 1 is cylindrical, with an internal cavity 11 inside and a perforation 12 communicating with the internal cavity 11 on the side wall of the embedding plate 1. In this embodiment, a plurality of wing plates 4 and a driving assembly 5 are also provided on the embedding plate 1. Specifically, the driving assembly 5 and the plurality of wing plates 4 are disposed in the internal cavity 11. The plurality of wing plates 4 have a transport state in which they retract into the interior of the embedding plate 1 and a working state in which they extend out of the embedding plate 1. The driving assembly 5 is connected to the plurality of wing plates 4 and drives the plurality of wing plates 4 to switch between the transport state and the working state. That is, in actual use, the plurality of wing plates 4 can enter and exit the internal cavity 11 through the perforation 12 under the action of the driving assembly 5, so as to present the aforementioned transport state and working state. At the same time, when the aforementioned pressure plate 6 presses against the embedding plate 1, the driving assembly 5 can maintain the driving of the wing plates 4.

[0061] Specifically, the drive assembly 5 includes an operating part 51 and a rotating part 52. The operating part 51 is disposed above the embedding plate 1, and the rotating part 52 is disposed inside the embedding plate 1 and fixedly connected to the operating part 51. The rotating part 52, driven by the operating part 51, causes the wing plate 4 to retract or extend. Figure 2 and Figure 3 As shown, an operating part 51 is spaced apart above the embedding plate 1. The operating part 51 is connected to a rotating component 52 inside the built-in cavity 11 via a connecting rod. In this embodiment, the rotating component 52 includes a body 521 and a turntable 522. The body 521 is relatively fixed in the built-in cavity 11, and a groove 524 is formed on the body 521, within which the wing plate 4 is movably disposed. Meanwhile, the turntable 522 is rotatably disposed on the upper surface 61 of the body 521, and rotation of the turntable 522 allows the wing plate 4 to move within the groove 524. The axes of the turntable 522, the connecting rod, and the operating part 51 are the same. The user can rotate the operating part 51, thereby rotating the turntable 522, which in turn acts on the wing plate 4, causing the wing plate 4 to retract or extend.

[0062] In some embodiments of the present invention, the rotating member 52 is provided with a plurality of arc-shaped guide grooves 523, which are correspondingly arranged one-to-one with the wing plate 4. A sliding post 43 is constructed on the wing plate 4, and the sliding post 43 is slidably disposed within the arc-shaped guide groove 523. The arc-shaped guide groove 523 can guide the sliding post 43 to slide along its opening direction, so that the wing plate 4 retracts or extends. Specifically, the aforementioned arc-shaped guide grooves 523 are all formed on the turntable 522, and a sliding post 43 is constructed at one end of the wing plate 4 located within the sliding groove 524. The sliding post 43 is located within the arc-shaped guide groove 523, as described above. Figure 3As shown, when the turntable 522 rotates, the sliding column 43 will move due to the guidance of the arc-shaped guide groove 523, moving from one end of the arc-shaped guide groove 523 to the other end. At the same time, due to the action of the arc-shaped guide groove 523, the wing plate 4 will also move in the sliding groove 524, thereby enabling the wing plate 4 to extend or retract.

[0063] Of course, it should be noted that, in addition to the combination of the arc-shaped guide groove 523 and the sliding column 43, other methods can also be used to make the rotating part 52 have the function of driving the wing plate 4 to retract or extend.

[0064] In this embodiment, a plurality of wing plates 4 are arranged at intervals along the circumference of the rotating member 52. Specifically, there are six wing plates 4, each corresponding to one of the aforementioned arc-shaped guide grooves 523 and sliding grooves 524. Simultaneously, there are also six perforations 12 formed on the side wall of the embedding plate 1, each corresponding to one of the wing plates 4, to allow the wing plates 4 to retract or extend. In this embodiment, the plurality of wing plates 4 are arranged in a ring-shaped interval around the axis of the turntable 522, that is, the plurality of wing plates 4 are arranged along the axial direction of the rotating member 52. As before... Figure 3 As shown, the wing plate 4 includes a main body 41 and a pull rod 42. The main body 41 has a cuboid structure, and one end of the pull rod 42 is connected to the main body 41. The pull rod 42 is located within a groove 524, and a sliding post 43 is constructed at the other end of the pull rod 42. The use of annular and spaced-apart wing plates 4 helps to further improve the stability of the mounting plate 1 during installation. Of course, other numbers of wing plates 4 can also be used. When there are six wing plates 4, the stress on the mounting plate 1 is more even, and the signal tower is better fixed.

[0065] It should be noted that, in addition to the above-mentioned insertion method of the insertion hole 511 and the limiting post 64, other structures can also be used to restrict the movement of the operating part 51, such as the method of the operating part 51 engaging with the groove 63, etc., which will not be described in detail here, as long as the rotation of the operating part 51 is restricted.

[0066] In some embodiments of the present invention, the fixing component 2 includes a positioning plate 21, a connector 22, and a fastener 23. The positioning plate 21 is disposed above the pressure plate 6, and is fixed to the embedding plate 1 by the connector 22. The fastener 23 is used to fix the mounting ring 32 of the tower rod 3 to the positioning plate 21. Figure 2 , Figure 4 and Figure 5As shown, the connector 22 is fixed to the upper surface 61 of the mounting plate 1, and the positioning plate 21 is located on top of the connector 22. In this embodiment, the connector 22 is tubular and is used to protect the pull wire 71 of the detection component 7 from being affected by soil or concrete. The aforementioned operating parts 51 are spaced apart in the middle of the connector 22. Meanwhile, a mounting ring 32 is constructed on the tower 3, and a fixing hole is provided on the mounting ring 32. A mounting hole 25 is provided on the positioning plate 21, and the fastener 23 is set as a bolt. The bolt passes through the fixing hole and is screwed into the mounting hole 25 to fix the tower 3 to the positioning plate 21.

[0067] Still Figure 2 and Figure 3 As shown, the pressure plate 6 is spaced above the embedding plate 1 and is positioned between the tower rod 3 and the embedding plate 1. When the mounting ring 32 is fixed on the positioning plate 21, the tower rod 3 will press against the pressure plate 6 and press the pressure plate 6 against the upper surface 61 of the embedding plate 1.

[0068] In this embodiment, an insertion hole 511 is provided on the operating part 51, and a limiting post 64 is constructed on the pressure plate 6. The limiting post 64 protrudes into the insertion hole 511 as the pressure plate 6 moves downward, so that the rotating member 52 maintains its drive on the wing plate 4. Specifically, a groove 63 is provided at the bottom of the pressure plate 6, and two insertion holes 511 are also provided at the top of the operating part 51, and two limiting posts 64 are constructed inside the groove 63. In this embodiment, when the pressure plate 6 presses against the upper surface 61 of the embedding plate 1, the operating part 51 is located in the groove 63 of the pressure plate 6, and the limiting post 64 protrudes into the insertion hole 511. Of course, when the pressure plate 6 presses against the embedding plate 1, the embedding plate 1 is necessarily used for embedding and installation. At this time, the wing plate 4 is in a working state that protrudes outside the embedding plate 1.

[0069] In some embodiments of the present invention, a conical sleeve 33 is provided on the tower 3, and a conical groove 24 coupled to the conical sleeve 33 is provided on the positioning plate 21. For example... Figure 3-5 As shown, a conical sleeve 33 is provided on the tower 3 and below the mounting ring 32. Correspondingly, a conical groove 24 is provided on the positioning plate 21. When the mounting ring 32 is fixed on the positioning plate 21, the conical sleeve 33 fits adaptively in the conical groove 24. As the conical sleeve 33 gradually penetrates into the conical groove 24, it can be squeezed and deformed, thereby further locking the position of the tower 3 and effectively preventing the tower 3 from shaking.

[0070] In some embodiments of the present invention, the detection component 7 includes a pull wire 71, a movable member 72, and a detection member 73. One end of the pull wire 71 is fixed to the upper surface 61 of the pressure plate 6. The tower rod 3 presses against the pressure plate 6, and a portion of the pull wire 71 is pressed into the receiving groove 62 of the pressure plate 6. The detection point is the connection between the pull wire 71 and the edge of the contact surface 31. The movable member 72 is slidably disposed on the positioning plate 21, and is connected to the other end of the pull wire 71. The movable member 72 moves downward as the pressure plate 6 moves downward under the action of the pull wire 71. The detection member 73 is disposed on the positioning plate 21 and is used to detect the downward movement distance of the movable member 72.

[0071] Specifically, such as Figure 2 , Figure 5 and Figure 6 As shown, a receiving groove 62 is provided on the upper surface 61 of the pressure plate 6. One end of the pull wire 71 is fixed in the receiving groove 62. When the tower rod 3 presses against the pressure plate 6 and the pressure plate 6 abuts against the embedded plate 1, a portion of the pull wire 71 is also pressed into the receiving groove 62 of the pressure plate 6. At this time, the connection point between the pull wire 71 and the edge of the contact surface 31 of the tower rod 3 is the detection point. In this embodiment, there are eight detection components 7 arranged in a ring around the circumference of the pressure plate 6, so there are eight detection points, which are spaced apart at the edge of the contact surface 31.

[0072] In this embodiment, the pull wire 71 is a steel wire rope. When the pull wire 71 is partially pressed into the receiving groove 62, that is, when the tower rod 3 is installed on the fixing component 2, the pull wire 71 is taut, and at this time, the movable member 72 will move downward relative to the positioning plate 21. The detection member 73 determines the contact effect between the tower rod 3 and the pressure plate 6 by detecting the downward movement distance of the movable member 72, thereby determining whether the tower rod 3 is deflected relative to the pressure plate 6, and further determining whether the tower rod 3 is vertical. When the tower rod 3 is not installed on the fixing component 2, the pull wire 71 can be in a slack or taut state, but at this time the pull wire 71 does not have the ability to move the movable member 72, and the pull wire 71 can suspend the pressure plate 6 above the embedding plate 1, so that there is a gap between the pressure plate 6 and the embedding plate 1, which serves as the movement space for the pressure plate. Of course, the pressure plate 6 and the embedding plate 1 are spaced apart, but other methods can also be used, such as setting a spring and a guide rod that can be inserted into or pass through the pressure plate 6 between the pressure plate 6 and the embedding plate 1.

[0073] In some embodiments of the present invention, the detection component 7 further includes a fixing plate 74 and an elastic element 75. The fixing plate 74 is disposed in the pull-out groove 211 of the positioning disk 21, and the elastic element 75 is disposed between the fixing plate 74 and the movable member 72, having a compressed state that causes the movable member 72 to move upward. Specifically, the positioning disk 21 has a pull-out groove 211, the fixing plate 74 is fixed at the opening of the pull-out groove 211, the elastic element 75 is located in the middle of the pull-out groove 211, the detection element 73 is disposed at the bottom of the pull-out groove 211, and the pull wire 71 passes through the fixing plate 74 and connects to the movable member 72. In this embodiment, the elastic element 75 is a spring, and when the pull wire 71 is in a straight state, the spring is in a compressed state.

[0074] Still Figure 5 and Figure 6 As shown, an annular boss 26 is provided on the positioning plate 21. The inner wall of the boss 26 fits against the outer peripheral surface of the mounting ring 32 to further enhance the restraint on the tower rod 3. The aforementioned pull-out groove 211 extends into the boss 26. The movable member 72 includes a horizontal plate 721 connected to the pull wire 71 and a test post 722 disposed on the horizontal plate 721. In this embodiment, the boss 26 and the positioning plate 21 are integrally formed, and the opening of the pull-out groove 211 faces downward. The detection member 73 is a pressure sensor. The test post 722 abuts against the detection surface of the pressure sensor. In conjunction with the aforementioned spring, the downward movement distance of the movable member 72 can be determined by detecting the data from the pressure sensor, thereby determining whether the tower rod 3 is vertical.

[0075] Of course, the specific structure of the detection component 7 can also take other forms, such as setting the detection component 73 as a distance sensor; the fixing plate 74 and the positioning plate 21 are integrally formed, and the boss 26 and the positioning plate 21 are detachably set; so that by detecting the fitting effect between the pressure plate 6 and the tower rod 3, it can be determined whether the tower rod 3 has deflected relative to the buried plate 1, and thus determine whether the tower rod 3 is vertical.

[0076] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
