Technical Field

[0001] This invention relates to the field of landscape tower technology, specifically to irregularly shaped landscape towers and their installation methods. Background Technology

[0002] Landscape towers, also known as craft towers or stainless steel towers, are particularly suitable for landmark buildings and the rooftops of major office buildings.

[0003] For example, a Chinese patent discloses "A Landscape Tower" (patent number: CN2020 Lighting Lamp 10863973.3), which includes a tower structure. It solves the problem of monotonous lighting and the need for additional power supply in existing landscape towers. This landscape tower includes a tower tube, with a section of the tower body circumferentially distributed with vertically oriented guide grooves. A slider slides within the guide grooves, and a generator and LED lights are mounted on the slider. The generator powers the LED lights, and a gear is mounted on the generator's drive shaft. An elliptical ring is obliquely fitted onto the tower body section with the guide grooves. The generator is located above the elliptical ring, and the elliptical ring has teeth that mesh with the gear on the generator shaft. The elliptical ring is fixed to a circular ring, which rotatably fits onto the tower tube. Wind turbine blades are circumferentially distributed on the circular ring, and the upper end of the elliptical ring is lower than the top of the guide grooves. The lighting of this landscape tower can change with the wind, and the electricity is provided by wind power.

[0004] However, while the aforementioned landscape towers meet basic lighting adjustment requirements, they have issues with adjusting the angle of illumination. Furthermore, given their high placement, convenient installation is crucial to minimize installation problems and improve installation efficiency. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides an irregularly shaped landscape tower and its installation method, thus solving the problems mentioned in the background section.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: an irregularly shaped landscape tower, comprising a tower body, fixed rods, a rotating support plate, a mounting plate, a mounting sealing plate, and a lifting adjustment plate. The tower body is vertical and its height can be increased as needed. A support ring plate is provided on the outer side of the tower body. The support ring plate is cylindrical in shape and has a vertically connected support cavity inside. Several support connecting rods are provided in the support cavity and are fixedly connected to the tower body. Several fixed rods are fixedly disposed on the upper surface of the support ring plate. The fixed rods are arranged in a ring shape, and the upper surface of the fixed rods has an upward-opening hinge groove. The fixed rods rotate within the hinge groove. A hinge shaft is provided, and a hinge connecting plate is fixedly connected to the outer end face of the hinge shaft. A rotating support plate is fixedly installed on the upper end face of the hinge connecting plate. Two outward-facing slots are provided on the upper side of the outer end face of the landscape tower body. The slots on both sides are symmetrically positioned externally. An installation plate is installed and inserted into the slots on both sides. The installation plate is fixedly connected to one end face of the installation plate. An installation sealing plate is provided above the landscape tower body. The installation sealing plate is used to fix the upper two sides of the installation plate. A lifting adjustment plate that can move up and down is provided above the support ring plate. The lifting adjustment plate is sleeved on the outside of all the fixed rods. Two connecting blocks are fixedly provided on the inner arc surface of the lifting adjustment plate. The connecting blocks on both sides are symmetrically positioned.

[0009] Preferably, the mounting plate has a downward-opening clamping cavity on its lower inner side, and a drive shaft is rotatably provided between the two walls of the clamping cavity. Two threaded sleeves are fixedly sleeved on the outer end face of the drive shaft.

[0010] Preferably, two movable stabilizing clamps are provided on both sides of the clamping cavity. The stabilizing clamps on both sides are symmetrically positioned and are threadedly connected to the threaded sleeve. One end of the drive shaft extends outward and is fixedly connected to a rotating disk.

[0011] Preferably, the hinge shaft has hinge caps fixedly connected to both ends extending outwards, and an arc-shaped support rod is installed on the upper surface of the rotating support plate. Two connecting plates are fixedly installed on the lower side of the outer end face of the arc-shaped support rod. The connecting plates on both sides are symmetrically positioned, and the connecting plates on both sides are convenient for threaded connection with the rotating support plate.

[0012] Preferably, the other end face of the arc-shaped support rod is provided with a street light slot with an outward opening. The street light slot is provided with a detachable street light connector plate. The street light connector plate and the street light slot are fixedly connected by a mounting block. A lighting lamp is fixedly provided on one end face of the street light connector plate.

[0013] Preferably, the mounting plate has an outward-facing lifting cavity, a lifting threaded shaft is provided between the upper and lower walls of the lifting cavity, and a lifting slider that can move up and down is provided in the lifting cavity, the lifting slider being threadedly connected to the lifting threaded shaft.

[0014] Preferably, a horizontally arranged adjusting rod is fixedly connected to one end of the lifting slider, and the end face of the adjusting rod away from the mounting plate has an outwardly opening connecting groove.

[0015] The following are the specific steps for installing an irregularly shaped landscape tower:

[0016] The first step involves fixing the landscape tower in its installation position. Workers then slide the lifting adjustment plate onto the outside of the tower. Next, they hold the rotating support plate and move it above the support ring plate using the curved support rod. They then insert the hinge plate into the hinge slot and insert the hinge shaft into the slot from the side. The hinge caps on both sides are then used to seal and fix the connection, thus completing the hinged relationship between the rotating support plate and the fixed rod. Finally, workers hold the installed lighting fixture and insert the streetlight mounting plate into the streetlight slot, using the mounting blocks for stable support. This allows for easy disassembly and replacement of the lighting fixture if it malfunctions.

[0017] The second step involves the worker holding the installation plate and inserting it into the slot from top to bottom. The lower end of the threaded installation plate is then threaded into the lower side of the slot's inner wall, completing the initial installation. Next, the worker holds the installation sealing plate and moves it above the landscape tower. By rotating the sealing plate, the worker adjusts the stabilizing clamps on both sides, moving them to the outer sides of the corresponding installation plates. The worker then manually rotates the rotating disc, which in turn rotates the drive shaft, causing the threaded sleeves on both sides to rotate. Since the threads on the two sleeves are opposite, the rotation causes the stabilizing clamps on both sides to move closer together, thus securing the upper ends of the installation plates on both sides and improving the subsequent installation stability.

[0018] The third step involves the worker holding the lifting adjustment plate and moving it upwards until it reaches the corresponding adjustment rod height. Then, the worker rotates the lifting adjustment plate to rotate the connecting blocks on both sides until they reach the corresponding connecting slots. After inserting the connecting blocks into the connecting slots and securing them with threaded nuts, the installation is complete.

[0019] (III) Beneficial Effects

[0020] This invention provides an irregularly shaped landscape tower and its installation method. It has the following beneficial effects:

[0021] 1. All connecting parts in this solution are equipped with slots and threaded grooves to facilitate the matching and installation by the staff.

[0022] 2. During the installation process, the staff can control the stabilizing clamps on both sides to move closer to each other, thereby stably clamping and connecting the upper ends of the mounting plates on both sides, thus improving the subsequent installation stability of the mounting plates. Furthermore, the external mounting sealing plate protects the top of the landscape tower and further facilitates the installation work.

[0023] 3. This solution uses a ring-shaped lifting and adjusting plate to drive the arc-shaped support rod to deflect and rotate, thereby causing the lighting lamp to deflect and change the lighting angle. This improves the overall aesthetics of the landscape tower without affecting its normal use, while increasing the lighting range and making the lighting efficiency more efficient. At the same time, the lifting and adjusting plate provides subsequent stable support, improving the lighting stability of the lamp. Attached Figure Description

[0033] This invention provides an irregularly shaped landscape tower, such as... Figure 1-8 As shown, the structure includes a landscape tower body 101, fixed rods 116, a rotating support plate 105, a mounting plate 113, a mounting sealing plate 111, and a lifting adjustment plate 106. The landscape tower body 101 is vertical and its height can be increased as needed. A support ring plate 102 is provided on the outer side of the landscape tower body 101. The support ring plate 102 is cylindrical and has a vertically connected support cavity 104 inside. Several support connecting rods 103 are provided in the support cavity 104 and are fixedly connected to the landscape tower body 101. Several fixed rods 116 are fixedly installed on the upper surface of the support ring plate 102. The fixed rods 116 are arranged in a ring. The upper surface of the fixed rods 116 has an upward-opening hinge groove 129. A hinge shaft 130 is rotatably installed in the hinge groove 129. A hinged connecting plate 131 is fixedly connected to the outer end face of 130. A rotating support plate 105 is fixedly installed on the upper end face of the hinged connecting plate 131. Two slots 120 with outward openings are provided on the upper side of the outer end face of the landscape tower body 101. The two slots 120 are symmetrically positioned on the outside. An installation plate 121 is installed and inserted in the two slots 120. An installation plate 113 is fixedly connected to one end face of the installation plate 121. An installation sealing plate 111 is provided above the landscape tower body 101. The installation sealing plate 111 is used to fix the upper two sides of the installation plate 121. A lifting adjustment plate 106 that can move up and down is provided above the support ring plate 102. The lifting adjustment plate 106 is sleeved on the outside of all the fixed rods 116. Two connecting blocks 123 are fixedly provided on the inner arc surface of the lifting adjustment plate 106. The two connecting blocks 123 are symmetrically positioned.

[0034] It should be noted that the lifting adjustment plate 106 is annular, the mounting sealing plate 111 is disc-shaped, the slot 120 has a threaded hole on the lower side, and the mounting plate 121 has a corresponding threaded hole on the lower side.

[0035] like Figure 5As shown, the lower side of the mounting plate 111 is provided with a clamping cavity 125 with an opening facing downward. A drive shaft 124 is rotatably provided between the two walls of the clamping cavity 125. Two threaded sleeves 128 are fixedly sleeved on the outer end face of the drive shaft 124.

[0036] It is worth noting that the two threaded sleeves 128 are symmetrically positioned, and the two threaded sleeves 128 are threaded, with the threads on the two threaded sleeves 128 being opposite.

[0037] Furthermore, two movable stabilizing clamps 126 are provided on both sides of the clamping cavity 125. The stabilizing clamps 126 on both sides are symmetrically positioned and are threadedly connected to the threaded sleeve 128. One end of the drive shaft 124 extends outward and is fixedly connected to a rotating disk 119.

[0038] It should be noted that the lower end of the stabilizing clamp 126 is relatively wide, and the stabilizing clamp 126 is made of hard metal material.

[0039] like Figure 6 and Figure 7 As shown, hinged shaft 130 has hinged caps 117 that extend outward from both ends and are fixedly connected to it. An arc-shaped support rod 107 is installed on the upper end of the rotating support plate 105. Two connecting plates 134 are fixedly installed on the lower side of the outer end of the arc-shaped support rod 107. The two connecting plates 134 are symmetrically positioned and can be easily connected to the rotating support plate 105 by threads.

[0040] It should be noted that the arc-shaped support rod 107 is curved.

[0041] Furthermore, the other end face of the arc-shaped support rod 107 is provided with a street light slot 133 with an outward opening. The street light slot 133 is provided with a detachable street light connector plate 115. The street light connector plate 115 and the street light slot 133 are fixedly connected by an installation plug 132. A lighting lamp 108 is fixedly installed on one end face of the street light connector plate 115.

[0042] It should be specifically noted that the lighting lamp 108 is a light-sensing lamp of the prior art center, which can change the lighting brightness according to the intensity of light.

[0043] like Figures 1-3 As shown, the mounting plate 113 has an outward-facing lifting cavity 118. A lifting threaded shaft 109 is provided between the upper and lower walls of the lifting cavity 118. A lifting slider 135 that can move up and down is provided in the lifting cavity 118. The lifting slider 135 is threadedly connected to the lifting threaded shaft 109.

[0044] Furthermore, a horizontally arranged adjusting rod 114 is fixedly connected to one side of the lifting slider 135, and the adjusting rod 114 has an outwardly opening connecting groove 122 on the side face away from the mounting plate 113.

[0045] It should be noted that the width of the groove 122 matches the width of the connecting block 123, the groove 122 has a threaded hole, and the connecting block 123 has a through threaded hole.

[0046] It should be noted that a lifting motor, as in the prior art, is fixedly installed inside the mounting plate 113, and the lifting threaded shaft 109 is poweredly connected to the lifting motor.

[0047] When this solution is used, the start of the lifting motor can drive the lifting threaded shaft 109 to rotate. At this time, the rotation of the lifting threaded shaft 109 drives the lifting slider 135 to move up and down through the threaded connection, which in turn drives the adjusting rod 114 to move up and down.

[0048] The specific steps of the irregularly shaped landscape tower and its installation method of the present invention are as follows:

[0049] First, after fixing the landscape tower 101 in the installation position, the staff first puts the lifting adjustment plate 106 onto the outside of the landscape tower 101. At this time, the staff holds the rotating support plate 105 and moves it above the support ring plate 102 by driving the arc-shaped support rod 107. Then, the staff inserts the hinge plate 131 into the hinge groove 129 and inserts the hinge shaft 130 into the hinge groove 129 from the side. Then, the hinge caps 117 on both sides are used to close and fix it, thus completing the hinge relationship between the rotating support plate 105 and the fixed rod 116. Then, the staff holds the installed lighting lamp 108 and inserts the street lamp connector plate 115 into the street lamp slot 133. The installation plug 132 is used to provide stable support. When the lighting lamp 108 is damaged, the staff can easily disassemble and replace the lighting lamp 108.

[0050] In the second step, the worker holds the mounting plate 113 and inserts the mounting plate 121 from top to bottom into the slot 120. The lower end of the threaded mounting plate 121 is then threaded into the lower side of the inner wall of the slot 120, completing the initial installation. Next, the worker holds the mounting sealing plate 111 and moves it above the landscape tower body 101. By rotating the mounting sealing plate 111, the worker adjusts the stabilizing clamps 126 on both sides to their corresponding outer sides of the mounting plates 121 and stops. Then, the worker manually rotates the rotating disk 119, which in turn drives the drive shaft 124 to rotate, thereby rotating the threaded sleeves 128 on both sides. Since the threads of the threaded sleeves 128 on both sides are opposite, during rotation, the stabilizing clamps 126 on both sides move closer together, thus stably clamping and connecting the upper ends of the mounting plates 121 on both sides, thereby improving the subsequent installation stability of the mounting plates 121.

[0051] The third step involves the worker holding the lifting adjustment plate 106 and moving it upwards until it reaches the height of the corresponding adjustment rod 114. Then, the worker rotates the lifting adjustment plate 106, causing the connecting blocks 123 on both sides to rotate and stop at the corresponding connecting groove 122. After that, the worker inserts the connecting blocks 123 into the connecting groove 122 and secures the connection with threaded nuts, thus completing the installation.

[0052] When using this solution, illumination can be provided at night by the lighting lamp 108. When the lighting angle needs to be adjusted, the lifting motor starts, which drives the lifting threaded shaft 109 to rotate. At this time, the rotation of the lifting threaded shaft 109 drives the lifting slider 135 to move up and down through the threaded connection, which in turn drives the adjusting rod 114 to move up and down. As the adjusting rod 114 moves up and down, it can drive the connecting block 123 connected to the adjusting rod 114 to move. At this time, after the lifting adjusting plate 106 is moved by the support connection of the connecting block 123, the lifting adjusting plate 106 comes into contact with the inner arc surface of the arc-shaped support rod 107, which then drives the arc-shaped support rod 107 to move. 07. The rotating support plate 105 and the fixed rod 116 are pivoted at the pivot point. The pivoted arc support rod 107 then drives the lighting lamp 108 to pivot, thereby changing the lighting angle of the lighting lamp 108. This improves the overall aesthetics of the landscape tower 101 without affecting its normal use, while also increasing the lighting range of the lighting lamp 108 and making its lighting efficiency more efficient. Furthermore, the lifting adjustment plate 106, with its curved inner ring, provides support and protection for the arc support rod 107, further facilitating the stability of the lighting angle of the lighting lamp 108.

[0053] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

At this time, the staff held the rotating support plate (105) and moved it above the support ring plate (102) by driving the arc support rod (107). Then, the staff inserted the hinge plate (131) into the hinge groove (129) and inserted the hinge shaft (130) into the hinge groove (129) from the side. Then, the hinge caps (117) on both sides were used to close and fix it, thus completing the hinge relationship between the rotating support plate (105) and the fixed rod (116). Then, the staff held the installed lighting lamp (108) and inserted the street lamp plate (115) into the street lamp slot (133). The installation plug (132) was used to provide stable support. When the lighting lamp (108) is damaged, the staff can easily disassemble and replace the lighting lamp (108). In the second step, the staff holds the installation plate (113) and inserts the installation plate (121) from top to bottom into the slot (120).
