Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of inclination monitoring, in particular to a micro power transmission tower inclination monitoring device. BACKGROUND

[0002] The inclination monitoring device is a monitoring device based on the principle of angle measurement for monitoring the inclination state of buildings and structures. Current inclination monitoring devices are mainly divided into two categories. One is a manual inspection tool such as a ruler and a total station instrument, which requires manual operation of the instrument to measure the inclination. The other is a sensor type device that continuously monitors the inclination of the tower by combining an inclination sensor with wireless transmission monitoring. These inclination monitoring devices are used in the field of power transmission. The micro power transmission tower, as a temporary power supply core equipment in construction, emergency rescue and other scenes, is small in size, easy to install, low in cost, made of light materials, does not require complex foundation, and can quickly build temporary lines. However, due to the instability of the foundation of the temporary power transmission tower and the mechanical collision in the construction site, the temporary power transmission tower is prone to tilting in the construction site. Therefore, an inclination monitoring device is needed to continuously monitor the state of the temporary power transmission tower to ensure timely maintenance when the temporary power transmission tower tilts, thereby ensuring power supply safety.

[0003] However, the prior art has the following problems:

[0004] The temporary power transmission tower has a high probability of tilting itself. If manual inspection tools are used for monitoring, workers need to be arranged to measure frequently, which not only occupies a large amount of human resources, but also significantly increases the overall labor cost of the project. In addition, although the sensor type monitoring device can achieve automatic monitoring, the equipment procurement and maintenance cost is high, which does not match the low cost and short-term use requirement of the temporary tower. More importantly, engineering machinery frequently comes and goes in the construction area, accompanied by a large amount of dust. The harsh working environment not only easily causes the sensor and the supporting electronic components to malfunction due to dust accumulation, but also may cause equipment damage due to accidental mechanical collision. Once damaged, it needs to be replaced or repaired, further generating additional economic expenditure, which is difficult to meet the economic and reliability requirements in the temporary power transmission scenario.

[0043] In order to make the purpose, technical scheme and advantages of the present application more clear, the technical scheme of the present application will be described in detail below. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0044] Embodiment 1

[0045] Since the construction temporary power transmission tower is a temporary facility, and the probability of inclination is relatively large, the manual inspection tool is used, and manual inclination monitoring is required frequently, which has high labor cost. The equipment cost of the sensor type device is high, and the engineering machinery frequently moves in the construction area, the dust is heavy, the working environment is relatively poor, the sensor type device and its electronic components are prone to failure or damaged due to collision, which causes great economic loss. In order to solve the above problems, the present embodiment is invented.

[0046] Please refer toFigure 1 - Figure 6 The micro transmission tower inclination monitoring device comprises a shell 1, a top plate 2 connected to the top of the shell 1, and a protective cover 3 installed on the top plate 2. An alarm assembly 4 is arranged in the shell 1, and the alarm assembly 4 comprises a hammer rod 42, four trigger rods 44, and an alarm 46. The hammer rod 42 can swing along with the inclination of the tower, and when the hammer rod 42 swings, it can trigger the alarm 46 through one of the trigger rods 44. The connection between the top of the shell 1 and the top plate 2 adopts a sealed design, which plays a role in waterproofing, dustproofing, and windproofing, avoiding the wind blowing the hammer rod 42. The protective cover 3 is made of transparent wear-resistant material and is detachably arranged, which is convenient for workers to observe the alarm 46 and the mechanism installed above the top plate 2, and also plays a role in waterproofing, dustproofing, and windproofing.

[0047] Further, please refer to Figure 3 、 Figure 4 The bottom of the top plate 2 is provided with a ball head sleeve 41, both ends of the hammer rod 42 are provided with a ball head and a weight, the ball head of the hammer rod 42 is movably connected with the ball head sleeve 41, and the inner wall of the shell 1 is provided with four first supports 43. Four trigger rods 44 are rotatably installed on the four first supports 43, respectively. The bottom of the trigger rod 44 is connected with a protrusion 45, the four protrusions 45 are arranged in a circumferential array around the weight of the hammer rod 42, and the four protrusions 45 are located on the movement track of the weight. The ball head sleeve 41 allows the ball head to rotate freely in the groove, ensuring that the hammer rod 42 can flexibly adjust the swinging direction along with the inclination of the tower. The first support 43 serves as the rotating fulcrum of the trigger rod 44, so that the trigger rod 44 can rotate like a lever around the first support 43. When the tower is not inclined, a safety gap is reserved between the protrusion 45 and the weight, preventing the weight from mistakenly touching the protrusion 45 due to slight vibration. When the inclination angle of the tower exceeds the normal vibration range, the hammer rod 42 swings in the direction of the tower inclination with the shell 1 as the stationary reference, so that the weight contacts and pushes the protrusion 45 in the corresponding direction when moving, causing the protrusion 45 to drive the trigger rod 44 connected thereto to rotate around the first support 43, and the end of the trigger rod 44 away from the protrusion 45 moves towards the alarm 46.

[0048] In addition, please refer to Figure 5 、 Figure 6The alarm 46 is installed on the top plate 2, four sleeves 47 are installed on the outer wall of the alarm 46, a compression switch 48 is sleeved and slid on the sleeve 47, an elastic wire is arranged between the compression switch 48 and the alarm 46, the compression switch 48 is divided into a fixed section and an elastic expansion section, the elastic expansion section of the compression switch 48 is connected with a contact block 49, the four contact blocks 49 are located on the movement track of the end of the trigger rod 44 away from the protruding block 45, and the end of the trigger rod 44 away from the protruding block 45 is in contact with the contact block 49 and can trigger the alarm 46 through the compression switch 48; the alarm 46 is internally integrated with a buzzer, the elastic wire has elasticity, the length of the elastic wire is slightly longer than the maximum expansion stroke of the compression switch 48 on the sleeve 47, the elastic wire can realize the circuit connection of the compression switch 48 and the alarm 46, and can be freely deformed when the compression switch 48 is expanded, so that the wire is prevented from being pulled and broken to affect the circuit conduction, when the end of the trigger rod 44 away from the protruding block 45 moves towards the alarm 46, the trigger rod 44 contacts and pushes the contact block 49 in the moving process, the contact block 49 is extruded to push the elastic expansion section of the compression switch 48 to shrink into the fixed section, when the elastic expansion section shrinks into the fixed section, the power supply circuit of the alarm 46 is conducted, the alarm function is immediately started, and as the distance of the elastic expansion section shrinking increases, the alarm frequency of the alarm 46 increases, the alarm 46 is also provided with a signal transmitter, can send the alarm signal to a remote upper monitoring device, prompts the staff to repair as soon as possible, when the tower resumes the vertical state, the weight resets and no longer extrudes the protruding block 45, the compression switch 48 pushes the elastic expansion section to reset by using the reset spring arranged in the compression switch 48, and the alarm stops, the mechanical extrusion triggering structure ensures the instantaneity of the alarm and the automaticity of the reset, does not need manual intervention, and has simple structure and low cost, and is suitable for construction temporary power transmission tower.

[0049] It is worth mentioning that, please refer to Figure 2 , Figure 9 - Figure 11, the alarm assembly 4 further comprises a display part 6, the display part 6 comprises four pointer blocks 62 and four scale plates 63, the pointer block 62 in the direction of the tower tilt can display the tilt angle through cooperation with the scale plate 63; the display part 6 further comprises four second supports 64 and four slide plates 61, the four slide plates 61 are all installed on the protective cover 3, the four pointer blocks 62 are respectively slidably installed on the four slide plates 61, the four scale plates 63 are respectively installed on the four slide plates 61, the four second supports 64 are all installed on the top plate 2, a rotating rod 65 is rotatably installed on the second support 64, a pin shaft 67 is installed on the end of the trigger lever 44 away from the protrusion 45, one end of the rotating rod 65 is connected with a magnetic block 66, the other end of the rotating rod 65 is provided with a sliding groove, the sliding grooves of the four rotating rods 65 are respectively slidably connected with the four pin shafts 67, when the pin shaft 67 moves, the magnetic block 66 is driven to slide along the inner wall of the protective cover 3 through the rotating rod 65, when the magnetic block 66 moves, the pointer block 62 is driven to slide in the slide plate 61 through magnetic force; the slide plate 61 is internally provided with a strip-shaped slide way parallel to the scale plate 63, the pointer block 62 can smoothly slide in the slide way, the limiting effect of the slide way ensures that the pointer block 62 always moves along the scale direction of the scale plate 63, avoiding deviation to cause reading error, the second support 64 serves as the rotating fulcrum of the rotating rod 65, so that the rotating rod 65 can make lever movement around the second support 64, the pin shaft 67 on the trigger lever 44 is embedded in the sliding groove of the rotating rod 65, when the trigger lever 44 rotates around the first support 43, the pin shaft 67 slides along the sliding groove and drives the rotating rod 65 to rotate, and then drives the magnetic block 66 at the other end of the rotating rod 65 to move along the inner wall of the protective cover 3, the magnetic block 66 and the pointer block 62 are respectively close to the inner wall and the outer wall of the protective cover 3, when the magnetic block 66 moves, the pointer block 62 is driven to slide in the slide plate 61 through magnetic force, since the swing angle of the hammer rod 42 is related to the rotation angle of the trigger lever 44, and the rotation angle of the trigger lever 44 is related to the rotation angle of the rotating rod 65, therefore, the moving distance of the magnetic block 66 is related to the swing angle of the hammer rod 42, the distance of the pointer block 62 is converted after the angle of the hammer rod 42 is swung and is set on the scale plate 63 in the form of scale, so that the scale on the scale plate 63 corresponds to the tower tilt angle, so that the pointer block 62 in the direction of the tower tilt can stay at the corresponding angle scale position of the scale plate 63 after moving, and the staff can read the tilt direction and the tilt angle of the tower by observing the four scale plates 63 and the four pointer blocks 62 on the protective cover 3, thereby providing accurate data support for subsequent maintenance and adjustment.

[0050] Embodiment 2

[0051] On the basis of embodiment 1, according to the different construction areas and different towers, the threshold value of the required tower tilt alarm also has certain differences, in order to solve the above problems, the embodiment is invented.

[0052] Please refer to Figure 2 , Figure 6 - Figure 8The alarm assembly 4 also includes an adjustment unit 5, which includes a tray 52 rotatably connected to the outer wall of the alarm 46. The tray 52 has four arc-shaped grooves, and four sliding shafts 51 are connected to the fixed sections of the four compression switches 48. The four sliding shafts 51 are slidably connected to the four arc-shaped grooves of the tray 52. ​​When the tray 52 rotates, it drives the four sliding shafts 51 closer to or further away from the alarm 46 via the four sliding grooves. The four arc-shaped grooves on the tray 52 are evenly distributed circumferentially, with the trajectory of the arc-shaped grooves centered on the center of the alarm 46. The groove walls are polished smooth to ensure that the sliding shafts 51 slide smoothly within the grooves without jamming. When the tray 52 rotates counterclockwise (e.g., when the four arc-shaped grooves rotate counterclockwise...), the adjustment unit 52 adjusts its position accordingly. Figure 8 As shown in the direction, the inner wall of the arc-shaped groove will generate a radial thrust on the sliding shaft 51, pushing the four sliding shafts 51 to move synchronously away from the alarm 46, thereby causing the fixed section of the compression switch 48 to slide outward along the sleeve 47, increasing the initial distance between the contact block 49 and the trigger rod 44; conversely, when the groove plate 52 rotates clockwise, the arc-shaped groove will pull the sliding shaft 51 to move closer to the alarm 46, and the compression switch 48 will retract inward, decreasing the initial distance between the contact block 49 and the trigger rod 44. By adjusting the initial distance between the contact block 49 and the trigger rod 44, the tower tilt alarm threshold can be adjusted to meet the differentiated requirements of different towers for the tilt alarm threshold.

[0053] It is worth noting that, please refer to Figure 7 , Figure 8 A crown gear ring 53 is installed on the tray 52, and two gear rods 54 are rotatably mounted through the protective cover 3. The two gear rods 54 are centrally symmetrically arranged, and each end of the gear rod 54 is provided with a handwheel and a gear. The gears of both gear rods 54 mesh with the crown gear ring 53. The handwheels of both gear rods 54 are located outside the protective cover 3. The handwheels of the gear rods 54 are designed with anti-slip texture, which makes it easy for the operator to rotate them by hand. When either handwheel is rotated, the handwheel drives the gear rod 54 to rotate around its own axis. The gear of the gear rod 54 drives the crown gear ring 53 to rotate through meshing transmission, and then drives the tray 52 to rotate synchronously. The arrangement of the two gear rods 54 allows the operator to rotate either handwheel according to their own position, and can also rotate both handwheels in opposite directions at the same time, achieving a labor-saving effect and improving the convenience of operation. The operator can adjust the alarm threshold by rotating the gear rods 54.
