Description

Technical Field

[0001] This utility model relates to the field of pole attachment devices, and in particular to a pole attachment device for automatically adjusting the direction of a sound column installation. Background Technology

[0002] Construction sites, dam reservoirs, and other similar areas are typically equipped with broadcasting and alarm systems for reporting information and emergency situations.

[0003] Currently, the sound columns of broadcasting and alarm systems are typically fixed to the top of poles. Once installed, the direction of sound wave radiation cannot be adjusted; it can only transmit sound in one direction. If the construction area changes or the location of the listeners shifts, adjustments to the sound field coverage must be made manually using lifting equipment or climbing the pole. This is inefficient, poses risks associated with working at height, and makes it difficult to achieve rapid and accurate acoustic positioning calibration and timely feedback adjustments. While it's possible to expand the sound field coverage by placing sound columns around the pole in multiple directions, this significantly increases investment costs.

[0004] Therefore, the existing methods of installing sound columns have problems such as the inability to dynamically adjust the direction, low efficiency of manual adjustment, and poor safety. Utility Model Content

One end of the connecting shaft is movably connected to the annular clamp through the drive unit, and the other end of the connecting shaft is fixedly connected to the sound column mounting frame.

[0008] As a preferred embodiment, the inner ring of the annular clamp is provided with a circumferential groove, and the connecting shaft is movably disposed within the circumferential groove.

[0009] Furthermore, the circumferential groove is a T-groove, the connecting shaft is a T-shaped rod, and the T-shaped head of the T-shaped rod is embedded in the T-groove and slides circumferentially along the T-groove.

[0010] Furthermore, silicone cushioning pads are provided at both ends of the T-shaped circumferential groove.

[0011] Furthermore, a rubber pad is affixed to the inner wall of the annular clamp where it contacts the upright.

[0012] As a preferred embodiment, the outer ring of the annular clamp is gear-shaped, integrally formed, and a locking hole is reserved at the tail end for fastening with bolts.

[0013] As a preferred embodiment, the connecting shaft includes an upper shaft and a lower shaft symmetrically arranged at the upper and lower ends of the annular clamp, and the sound column mounting bracket includes an upper mounting bracket and a lower mounting bracket. The end of the upper shaft is fixedly connected to the upper mounting bracket, and the end of the lower shaft is fixedly connected to the lower mounting bracket.

[0014] As a preferred embodiment, the drive unit includes an electric motor and a pinion, the output shaft of the electric motor is connected to the pinion, and the pinion meshes with the outer ring gear of the annular clamp.

This utility model provides a remotely controllable, automatically adjustable speaker column installation device to improve installation flexibility and management efficiency.

[0035] This utility model provides a pole attachment device for automatically adjusting the direction of a sound column installation, including an annular clamp 11, a connecting shaft, a sound column mounting frame, and a drive unit. The annular clamp 11 is a ring-shaped structure and is sleeved on the pole 2. The sound column mounting frame is set on the sound column 3. One end of the connecting shaft is movably connected to the annular clamp 11 through the drive unit, and the other end of the connecting shaft is fixedly connected to the sound column mounting frame to fix the sound column 3.

[0036] The inner ring of the annular clamp 11 has an circumferential groove 13, and the connecting shaft is movably disposed within the circumferential groove 13. The circumferential groove 13 is a T-shaped groove, and the connecting shaft is a T-shaped rod. The T-shaped head of the T-shaped rod is embedded in the T-shaped groove and slides circumferentially along the T-shaped groove. Silicone buffer pads are provided at both ends of the T-shaped circumferential groove 13. A rubber pad is attached to the part of the inner wall of the annular clamp 11 that contacts the upright. The outer ring of the annular clamp 11 is gear-shaped, integrally formed, and a locking hole is reserved at the tail end for fastening with bolts 12.

[0037] The connecting shaft includes an upper shaft 31 and a lower shaft 32 symmetrically arranged at the upper and lower ends of the annular clamp 11.

The gear meshing transmission ratio is 4:1, and the electric motor drives the sound column to rotate 90° for each revolution.

[0039] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] A pole attachment device for speaker column installation with automatic direction adjustment includes a fixing unit, a drive unit, a connecting unit, and a control unit. The fixing unit is primarily a ring-shaped clamp, with its outer ring machined into a large, integrally formed gear shape and its inner ring hollowed out with a T-shaped groove. The clamp's tail end is secured with bolts. The drive unit comprises an electric motor and a small gear fixed to its output shaft, the small gear meshing with the large gear. The connecting unit includes two speaker column mounting brackets and two T-shaped shafts at their ends. Each mounting bracket is anchored by bolts at four corners. The shaft ends are welded to the mounting brackets, and the T-shaped ends extend into the hollowed-out grooves in the clamp's inner ring, restricting longitudinal displacement of the speaker column while allowing it to slide along the circumferential groove path. The control unit is a signal receiver controller integrated into the speaker column's housing. It receives external wireless commands and controls the electric motor's start, stop, and rotation. Through gear transmission, the speaker column can rotate around the pole, changing the direction of sound wave transmission.

[0041] See Figure 1 , Figure 2 The schematic diagram of the overall structure of the automatically adjustable pole attachment device of this utility model includes a pole attachment device 1, a pole 2, and a sound column 3. The pole attachment device 1 is installed on the pole 2 and is used to drive the sound column 3 to automatically rotate around the pole 2 to adjust the direction of voice broadcasting.

[0042] This utility model is an example of an automatically adjustable pole attachment device, which includes a fixing unit, a driving unit, a connecting unit, and a control unit.

[0043] 1. Fixed unit

[0044] The annular clamp 11 is made of rolled steel plate, and its inner diameter is adapted to the diameter of the upright 2. A 3mm thick rubber pad is attached to the inner wall of the annular clamp 11 to enhance friction and prevent scratching the surface of the upright 2. The outer ring of the annular clamp 11 is a large gear shape, formed by laser integrated cutting, with a total of 40 teeth per ring. Because a locking section needs to be reserved at the tail end for fastening with high-strength bolts 12, the actual number of teeth is 34. The inner ring of the annular clamp 11 is machined with a T-shaped circumferential groove 13, 15mm deep and 20mm wide, to accommodate the T-shaped shaft 31 of the connecting unit.

[0045] 2. Drive Unit

[0046] The electric motor 21 is a DC geared electric motor, which is welded to the middle of the sound column via a bracket. The output shaft of the electric motor is connected to a small gear 22, which is the driving gear. The small gear 22 is made of alloy steel, is hardened, and has 10 teeth. The meshing transmission ratio with the driven gear of the outer ring of the ring clamp 11 is 4:1. The electric motor drives the sound column 3 to rotate 90° for every one revolution.

[0047] 3. Connection Unit

[0048] like Figure 3 As shown, the upper mounting bracket 33 and lower mounting bracket 34 of the two speaker column mounting frames are both square steel plates with pre-drilled bolt holes at the four corners for anchoring to the speaker columns. The two T-shaped shafts, upper shaft 31 and lower shaft 32, are made of stainless steel, with T-shaped heads at their ends. These T-shaped heads are embedded in the T-shaped circumferential groove 13 within the inner ring of the annular clamp 11, restricting the longitudinal displacement of the speaker column while simultaneously allowing circumferential sliding along the T-shaped circumferential groove 13. The other ends of the T-shaped shafts are welded to the back of the upper mounting bracket 33 and lower mounting bracket 34 of the two speaker column mounting frames, respectively. Silicone buffer pads are provided at both ends of the T-shaped circumferential groove 13 to prevent collision between the T-shaped heads of the two T-shaped shafts 31.

[0049] 4. Control Unit

[0050] The control unit is a signal receiver controller 41, integrated and soldered onto the speaker column housing. It supports 4G / Wi-Fi dual-mode wireless communication, receives external commands such as those from a mobile app or central control platform, and drives the electric motor to start, stop, and steer.

[0051] 5. Installation and Workflow

[0052] Fixing device: Place the ring clamp 11 on the target height of the upright 2, tighten the high-strength bolt 12 to the torque value, lock the locking hole through the bolt 12, and increase the friction of the inner wall rubber pad.

[0053] Assemble the sound column: Anchor the sound column base bolts to the two sound column mounting brackets 33 and 34, and insert the upper and lower T-shaped shafts 31 and 32 into the T-shaped circumferential grooves 13, as shown. Figure 4 The diagram shows the connection between the two T-shaped shafts and the inner section 14 of the clamp.

[0054] Directional adjustment: The administrator sends a command → the controller 41 parses the command → drives the electric motor 21 to rotate forward / reverse → drives the pinion 22 to roll along the ring clamp 11 → drives the upper shaft 31, lower shaft 32 and sound column of the T-shaped shaft to rotate around the axis of the upright to the target angle → when the rotation reaches the limit position, the silicone buffer pads at both ends of the T-shaped groove absorb the impact force. After reaching the target angle, the electric motor 21 automatically stops and triggers the electromagnetic brake to prevent wind disturbance and deviation.

[0055] All other undescribed parts belong to the prior art. The above-described embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
