DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example 1

[0030] See also Figure 1-Figure 8 , a power iron tower with a protective device shown in the figure includes a base 1, a protective mechanism, a limiting mechanism and an alarm mechanism. A tower body 2 is fixedly connected to the upper side of the base 1. A plurality of lower water tanks 35 are provided on the base 1. The lower water tanks 35 are used to discharge the accumulated water on the base 1 at the bottom of the tower body 2. The tower body 2 is a conical structure that is wide at the bottom and narrow at the top. The protective mechanism includes four groups of protective plates 3 installed on the base 1. A mounting groove 4 is provided on the side of the protective plate 3. A first rotating shaft 5 and a second rotating shaft 6 are rotatably connected in the mounting groove 4. The outer wall of the first rotating shaft 5 is transmission-connected with a transmission belt 7 that is transmission-connected to the outer wall of the second rotating shaft 6, which is used to control the flipping angle of the protective plate 3, so that when the protective plate 3 is in a vertical state, the transmission belt 7 on the side can rotate to avoid climbing. The limiting mechanism is installed on the protective plate 3, which is used to limit the first rotating shaft 5 when the protective plate 3 is in an inclined state to prevent the transmission belt 7 from continuing to rotate. The alarm mechanism is installed on the protective plate 3, which is used to sound an alarm when the transmission belt 7 rotates, warning people to stay away from the tower body 2.

[0031] The protective mechanism also includes a fixed block 8 fixedly installed on the upper side of the base 1, and the four sides of the fixed block 8 are rotatably connected to the first bevel gears 9, and the side of the first bevel gear 9 is coaxially fixedly connected to the threaded rod 10, and the upper side of the base 1 is slidably connected to four groups of push blocks 11 along the horizontal direction. The four groups of threaded rods 10 respectively penetrate the push blocks 11 and are threadedly connected to the push blocks 11. The side of the protective plate 3 is fixedly connected to a rotating buckle 12 rotatably connected to the push block 11, and the tower body 2 is provided with a driving member 13 for synchronously driving the four groups of first bevel gears 9 to rotate.

[0032] The protection mechanism also includes a fixed frame 14 fixedly installed on the side of the protection plate 3, a sliding block 15 is slidably connected in the fixed frame 14 along the horizontal direction, a connecting block 16 is rotatably connected to the sliding block 15, a guide groove 17 slidably connected to the connecting block 16 is opened on the bottom side of the tower body 2, and the guide groove 17 is inclined. The driving member 13 includes a driving motor 33 fixedly installed on the tower body 2. The model of the driving motor 33 is preferably Y80M1-2. The output end of the driving motor 33 is coaxially fixedly connected with a second bevel gear 34, and the second bevel gear 34 is meshed with multiple groups of first bevel gears 9.

[0033] In this embodiment, the problem that the existing power tower has poor protection effect and is difficult to open and close flexibly, which affects the maintenance efficiency is solved. In the protection state, the protection plate 3 is in a vertical state, and the transmission belts 7 around it are also in a vertical state. The limiting mechanism will not limit the rotation state of the first rotating shaft 5 and the second rotating shaft 6. When someone climbs around the tower body 2, the transmission belt 7 will be rotated, making it impossible to climb stably. At the same time, the alarm mechanism will be linked to operate and an alarm will be issued to remind people to stay away from the tower body 2 to avoid danger.

[0034] When carrying out maintenance, the control driving motor 33 drives the second bevel gear 34 to rotate, so that the four groups of first bevel gears 9 drive the threaded rod 10 to rotate, so that the pushing block 11 slides on the upper surface of the base 1, and the rotating buckle 12 is pushed to make the bottom of the protective plate 3 slide around, and at the same time drives the upper fixed frame 14 and the sliding block 15 to move downward, and the connecting block 16 slides in the guide groove 17 and is driven by the guide groove 17, so that the sliding block 15 slides horizontally in the fixed frame 14, and the connecting block 16 and the sliding block 15 rotate relative to each other, ensuring that the top end of the protective plate 3 is always limited and connected, and no deviation occurs. Until the connecting block 16 slides to the bottom position of the guide groove 17, the driving motor 33 stops running. The inclination angle of the protective plate 3 is small at this time, and the limiting mechanism limits the transmission belt 7, so that the maintenance personnel can walk on the upper side of the protective plate 3 and the transmission belt 7 to avoid affecting the maintenance efficiency.

[0035] It is worth noting that when the protective plate 3 rotates and moves in all directions, the sliding block 15 will link with the limiting mechanism to limit the rotation state of the first rotating shaft 5, thereby increasing the rotation resistance of the transmission belt 7 to avoid slipping and rotation during walking. At the same time, the bottom of the protective plate 3 will push the obstacles around the tower body 2 to the surroundings to avoid affecting the deployment of the protective plate 3. Some traditional deployment methods open by flipping the upper side to the surroundings, and cannot push away the obstacles on the surroundings. Once the bottom is blocked by an obstacle during the flipping process, it will get stuck and cannot be deployed.

[0036] Among them, a plurality of support shafts for supporting the inner wall of the transmission belt 7 can be further provided between the first rotating shaft 5 and the second rotating shaft 6 to enhance the supporting force of the side wall of the transmission belt 7 and avoid collapse during walking. The outer walls of the first rotating shaft 5 and the second rotating shaft 6 are provided with anti-slip grooves to enhance the friction between the transmission belt 7 and maintain the synchronization of the transmission process.

[0037] After the inspection is completed, the drive motor 33 is controlled to rotate in the opposite direction again, so that the threaded rod 10 drives the push block 11 to rotate the protective plate 3 to a vertical state, and the connecting block 16 is reset and slid from the bottom end of the guide groove 17 to the top end position of the guide groove 17 again.

[0038] Example 2

[0039] See also Figure 5-Figure 7 Embodiment 2 is described. This embodiment further describes Embodiment 1. The limiting mechanism shown in the figure includes a first connecting shaft 18 coaxially fixedly installed at both ends of the first rotating shaft 5. The outer wall of the first connecting shaft 18 is evenly provided with a plurality of groups of beveled tooth grooves 19. The protective plate 3 is provided with a device groove 20. A beveled tooth block 21 capable of being plugged into the beveled tooth groove 19 is slidably connected in the device groove 20. The sliding block 15 is provided with a control member 22 for controlling the plugging state of the beveled tooth block 21 and the beveled tooth groove 19 in linkage during sliding.

[0040] The control component 22 includes a liquid storage tube 23 fixedly installed in the fixed frame 14, the liquid storage tube 23 is used to store hydraulic oil, a sliding cavity 24 is provided in the sliding block 15, the outer wall of the liquid storage tube 23 is slidably connected with the inner wall of the sliding cavity 24, a connecting groove 25 connected to one end of the liquid storage tube 23 is provided on the fixed frame 14, and a sliding component 26 is provided in the device groove 20 for controlling the sliding state of the bevel gear block 21 according to the hydraulic strength in the connecting groove 25.

[0041] The sliding member 26 includes a tension spring 27 fixedly installed on the side of the bevel gear block 21, one end of the tension spring 27 is fixedly connected to the device groove 20, a driving rod 28 is fixedly connected to the side of the bevel gear block 21, a connecting pipe 29 is fixedly connected inside the protective plate 3, one end of the connecting pipe 29 is connected to the connecting groove 25, and the outer wall of the driving rod 28 is slidably connected to the inner wall of one end of the connecting pipe 29 away from the connecting groove 25.

[0042] In the present embodiment, since the guide groove 17 on the tower body 2 is inclined, when the protective plate 3 is in a vertical state, the sliding block 15 is at one end away from the connecting groove 25, and the sliding cavity 24 draws the hydraulic oil in the connecting pipe 29 into the liquid storage pipe 23, so that the hydraulic strength in the connecting pipe 29 is reduced, and the tension spring 27 pulls back, driving the driving rod 28 and the bevel tooth block 21 away from the bevel tooth groove 19. At this time, the first rotating shaft 5 can rotate freely in the mounting groove 4 to ensure the smooth rotation process of the transmission belt 7.

[0043] When the protective plate 3 rotates to the inclined state, the connecting block 16 slides to the bottom end position of the guide groove 17, driving the sliding block 15 to slide toward the side of the connecting groove 25, squeezing the hydraulic oil in the liquid storage tube 23, so that the hydraulic oil enters the connecting tube 29 through the connecting groove 25, and pushes the driving rod 28 and the bevel gear block 21 to slide toward the side of the first connecting shaft 18 until the bevel gear block 21 is inserted into the bevel gear groove 19, and the tension spring 27 is stretched. At this time, when people walk on the upper side of the transmission belt 7, due to the limiting effect of the bevel gear block 21 on the first connecting shaft 18 and the first rotating shaft 5, it is difficult for the transmission belt 7 to rotate freely, thereby improving the stability during the maintenance process and facilitating the maintenance personnel to approach the bottom of the tower body 2 for subsequent climbing operations.

[0044] Example 3

[0045] See also Figure 1-Figure 2 and Figure 8 Embodiment 3 is described. This embodiment further describes embodiment 1. The alarm mechanism shown in the figure includes a second connecting shaft 30 coaxially fixedly installed at both ends of the second rotating shaft 6. A plurality of groups of rattles 31 are evenly and fixedly connected to the outer wall of the second connecting shaft 30. A sound amplification groove 32 for transmitting the sound of the rattles 31 to the outside is provided on the side of the protective plate 3. A warning mark 36 for warning is provided on the outer wall of the transmission belt 7.

[0046] In the present embodiment, during the process of the transmission belt 7 being turned and rotated, the second rotating shaft 6 and the second connecting shaft 30 will be driven to rotate, so that the rattle 31 will rotate and make a sound, reminding people to stay away from the tower body 2 through hearing. At the same time, during the rotation of the transmission belt 7, the warning sign 36 will also rotate and switch, warning people visually to avoid danger. The warning device does not require motor control, is convenient and efficient to use, and has low cost.

[0047] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
