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 for monitoring the inclination state of buildings and structures based on the principle of angle measurement. 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 power transmission field. The micro power transmission tower is a temporary power supply core equipment in construction, emergency rescue and other scenes. It is small in size, easy to install and low in cost. It is made of light materials and does not require a complex foundation. It can quickly build a temporary line. 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 that the temporary power transmission tower can be repaired in time when it tilts, thereby ensuring power supply safety.

[0003] However, the prior art has the following problems: The temporary power transmission tower has a high probability of tilting. If a manual inspection tool is used for monitoring, a large number of personnel need to be arranged for frequent on-site measurement, which not only occupies a large number 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, and is 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.

DETAILED DESCRIPTION

[0020] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions 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 the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present application.

[0021] Embodiment 1 Since the construction temporary power transmission tower is a temporary facility, and the probability of tilting is relatively large, the manual inspection tool needs to be used for frequent tilting monitoring, and the labor cost is relatively high; and the equipment cost of the sensor type device is relatively high, and the construction area is frequently moved by the engineering machinery, the dust is relatively heavy, the working environment is relatively poor, the sensor type device and the electronic elements are prone to failure or damaged due to collision, causing a large economic loss, in order to solve the above problems, the embodiment is invented.

[0022] Please refer to Figure 1 Figure 6 , the micro power transmission tower tilting monitoring device, comprising: a shell 1, the top of the shell 1 is connected with a top plate 2, and the top plate 2 is installed with a protective cover 3; the shell 1 is provided with an alarm assembly 4, 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 tilting of the tower, and the hammer rod 42 can trigger the alarm 46 through one of the trigger rods 44 when swinging; the connection between the top of the shell 1 and the top plate 2 adopts a sealed design, which plays a role in waterproof, dustproof and windproof, avoids the wind blowing the hammer rod 42, and 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 waterproof, dustproof and windproof.

[0023] Further, please refer to​Figure 3 、 Figure 4 , the bottom of the top plate 2 is provided with a ball head sleeve 41, the hammer rod 42 is provided with a ball head and a weight at both ends, the ball head of the hammer rod 42 is movably connected with the ball head sleeve 41, 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, the trigger rods 44 are connected with protrusions 45 at the bottom, 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 freely rotate in the recess, so that the hammer rod 42 can be flexibly adjusted in the swinging direction along with the tower tilt, the first support 43 serves as a rotating support point of the trigger rod 44, so that the trigger rod 44 can be pivotally rotated as a lever, when the tower is not tilted, a safety gap is reserved between the protrusion 45 and the weight, so that the weight cannot mistakenly touch the protrusion 45 due to slight vibration, and when the tower is tilted at an angle exceeding the normal vibration range, the hammer rod 42 swings in the direction of the tower tilt with the shell 1 as a stationary reference, so that the weight contacts and pushes the protrusion 45 in the corresponding direction when moving, the protrusion 45 drives the trigger rod 44 connected therewith 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.

[0024] In addition, please refer to Figure 5 、 Figure 6, the alarm 46 is mounted on the top plate 2, and four sleeves 47 are installed on the outer wall of the alarm 46. A compression switch 48 is slidably sleeved on the sleeve 47, and 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 telescopic section. The elastic telescopic section of the compression switch 48 is connected with a resistance block 49. The four resistance blocks 49 are all located on the movement trajectory of the four trigger rods 44 away from the end of the protrusion 45. After the end of the trigger rod 44 away from the protrusion 45 contacts the resistance block 49, the alarm 46 can be triggered through the compression switch 48; the alarm 46 has an integrated buzzer, and the elastic wire is elastic, and its length is slightly longer than the maximum telescopic stroke of the compression switch 48 on the sleeve 47, which can not only realize the circuit connection between the compression switch 48 and the alarm 46, but also can deform freely when the compression switch 48 is extended and retracted, to avoid the wire being pulled and broken and affecting the circuit conduction. When one end of 45 moves toward the direction close to the alarm 46, the trigger rod 44 contacts and pushes the resistance block 49 during the movement. The resistance block 49 is squeezed and pushes the elastic telescopic section of the compression switch 48 to shrink into the fixed section. When the elastic telescopic section shrinks into the fixed section, the power supply circuit of the alarm 46 is connected, and the alarm function is immediately started. As the distance of the elastic telescopic section shrinks increases, the frequency of the alarm 46 will increase. The alarm 46 is also provided with a signal transmitter that can send the alarm signal to the remote upper monitoring equipment to prompt the staff to repair it as soon as possible. When the tower returns to the vertical state, the heavy hammer resets and no longer squeezes the protrusion 45. The compression switch 48 uses its own reset spring to push the elastic telescopic section to reset, and the alarm stops. This mechanical extrusion trigger structure ensures the immediacy of the alarm and the automaticity of the reset, without the need for human intervention, and has a simple structure and low cost, making it suitable for the construction of temporary transmission towers.

[0025] It is worth noting 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 by cooperating 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 reading error caused by deviation, 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 moving distance of the hammer rod 42 is converted, 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.

[0026] Embodiment 2 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.

[0028] It is worth noting that, please refer to Figure 7 , Figure 8 , a crown tooth ring 53 is installed on the groove disc 52, two tooth rods 54 are rotationally installed on the protective cover 3, the two tooth rods 54 are centrally symmetric, the two ends of the tooth rod 54 are respectively provided with a hand wheel and a gear, the gears of the two tooth rods 54 are in meshing engagement with the crown tooth ring 53, and the hand wheels of the two tooth rods 54 are located outside the protective cover 3; the hand wheel of the tooth rod 54 is designed with anti-slip pattern, which is convenient for the staff to rotate and operate by hand, when any one hand wheel is rotated, the hand wheel drives the tooth rod 54 to rotate around its own axis, the gear of the tooth rod 54 drives the crown tooth ring 53 to rotate through meshing transmission, and then synchronously drives the groove disc 52 to rotate, the setting of the two tooth rods 54 enables the staff to rotate any one hand wheel according to their own position, or to simultaneously rotate the two hand wheels in opposite directions, so as to save labor and improve the operation convenience, so that the staff can realize the adjustment of the alarm threshold by rotating the tooth rod 54.

[0029] Example 3 On the basis of example 1, due to the installation position limitation or other reasons, part of the towers will appear a certain inclination state after installation, and the shell 1 may directly trigger the alarm when installed on the tower which has been inclined, therefore, the shell 1 needs to be leveled, in order to solve the above problems, this example is invented.

[0030] Please refer to Figure 1、 Figure 11 Figure 13 The bottom of the shell 1 is provided with a leveling portion 8 for adjusting the shell 1 to a horizontal state; the leveling portion 8 comprises a cambered base 81 connected to the bottom of the shell 1 and a sleeve ring 82, the inner wall of the sleeve ring 82 is movably connected with the outer wall of the cambered base 81, the inner wall of the sleeve ring 82 is slidably connected with two locking blocks 83, the locking blocks 83 are rotatably connected with two lead screws 84, the ends of the lead screws 84 away from the locking blocks 83 penetrate through the sleeve ring 82, two nut seats 85 are installed on the sleeve ring 82, the two lead screws 84 are threadedly connected with the two nut seats 85, the ends of the lead screws 84 away from the locking blocks 83 are connected with two push rods 86, a connecting frame 87 is connected between the two push rods 86, a handle is arranged on the connecting frame 87, a counterweight 88 is installed on the bottom of the cambered base 81, the two locking blocks 83 can lock the cambered base 81, when the two locking blocks 83 do not lock the cambered base 81, the cambered base 81 can be self-adaptively leveled by the gravity of the counterweight 88; the outer wall of the cambered base 81 is a smooth arc surface, the inner wall of the sleeve ring 82 is matched with the arc surface of the outer wall of the cambered base 81 to form a movable connection capable of rotating at multiple angles, which provides space for the leveling and rotating of the cambered base 81, when operating, the staff only needs to push the handle on the connecting frame 87 upwards, which can synchronously drive the two push rods 86 to rotate upwards through the connecting frame 87, the push rods 86 further drive the lead screws 84 to rotate around the nut seats 85, since the lead screws 84 are threadedly connected with the nut seats 85, horizontal traction will be generated when the lead screws 84 rotate, which pulls the two locking blocks 83 to synchronously separate along the inner wall of the sleeve ring 82, quickly releasing the locking state of the cambered base 81, at this time, the counterweight 88 always pulls the cambered base 81 to keep a vertical downward trend by gravity, which makes the cambered base 81 drive the shell 1 to automatically rotate around the arc surface of the inner wall of the sleeve ring 82 until the counterweight 88 is completely vertical downward and the shell 1 synchronously reaches a horizontal state, the whole self-adaptive leveling process does not need manual repeated calibration, which is time-saving and efficient, after leveling is completed, the staff pushes the handle downwards again, the connecting frame 87 drives the push rods 86 and the lead screws 84 to reversely rotate, the lead screws 84 push the two locking blocks 83 to synchronously approach the cambered base 81 through the thread thrust, the two locking blocks 83 quickly lock the cambered base 81 through friction to fix it at a horizontal position, which avoids the shell 1 from deviating due to slight vibration of the tower in the subsequent process, ensuring the measurement accuracy of the alarm assembly 4 and the display portion 6, this operation mode of pushing the handle upwards and downwards only needs two simple actions to complete the process of unlocking, leveling and locking, which greatly improves the operation convenience and effectively shortens the leveling and fixing time.
