First embodiment
The embodiment provides a tower displacement monitoring device, as shown in fig. 1. The pole tower displacement monitoring device comprises a shell 1, a suspension mechanism 2 and a displacement measuring mechanism. The shell 1 is arranged on a tower; the suspension mechanism 2 is arranged in the shell 1 and comprises a connecting piece 5 and a heavy object 8, the top end of the connecting piece 5 is in universal connection with the shell 1, and the heavy object 8 is arranged at the bottom end of the connecting piece 5 so that the connecting piece 5 can rotate towards any direction relative to the shell 1 to keep a vertical state; the displacement measuring mechanism is provided in the housing 1, and includes a plurality of displacement meters 9, and the plurality of displacement meters 9 are provided around the outer peripheral surface of the weight 8 to measure the amount of displacement of the weight 8 with respect to the housing 1 in the direction corresponding to each displacement meter 9.
In this embodiment, in order to improve the accuracy of monitoring the tower displacement, the displacement measuring mechanism is totally arranged in 25 displacement meters 9. Specifically, the displacement meters 9 are placed one at every 45 degrees on a horizontal plane where the center of gravity of the weight 8 is located, and 8 displacement meters are placed in total; each displacement meter 9 on the horizontal plane is provided with 16 displacement meters 9 in total at the positions which rotate upwards or downwards by 45 degrees along the vertical direction by taking the gravity center of the heavy object 8 as the center of a circle; a displacement meter 9 is placed under the weight 8 so as to be in the direction of the perpendicular line where the center of gravity of the weight 8 is located, and 1 displacement meter is placed in total. The displacement measuring mechanism comprises a total of 25 displacement gauges 9.
In other embodiments, the number of the displacement meters 9 and the measurement direction of each displacement meter 9 may be adjusted as needed.
In the actual use process, after the tower displacement monitoring device is fixed on a tower and installed, when the suspension mechanism 2 is stably in a vertical state under the action of gravity, all the displacement meters 9 are zeroed to serve as the initial state of the device. If the measured tower has an inclination after the tower displacement monitoring device is installed, the tower displacement monitoring device can incline along with the tower, the process is slow, the suspension mechanism 2 can rotate around the universal connection point relative to the shell 1 to keep a vertical state, and at the moment, the heavy object 8 of the suspension mechanism 2 can generate a section of displacement. The displacement meters 9 surrounding the outer peripheral surface of the weight 8 can obtain the inclination angle and the displacement of the tower by measuring the displacement in each direction and performing data analysis.
Optionally, the displacement meter 9 comprises a body and a probe which is connected with the body and can be extended and retracted, the body is connected with the housing 1, and the probe can be abutted against the weight 8.
The displacement of the heavy object 8 is detected by the probe abutted against the heavy object 8, and the displacement in each direction is recorded according to the expansion and contraction amount of the probe, so that the real displacement and direction of the heavy object 8 are analyzed. Because the displacement meter 9 has extremely high precision, the tower displacement monitoring device using the displacement meter 9 also has extremely high precision. Meanwhile, the displacement meter 9 measures the displacement of the weight 8 in real time, and the tower displacement monitoring device can measure the inclination condition of the tower in real time.
Preferably, the weight 8 is a sphere and the plurality of displacement meters 9 are evenly distributed around the sphere of the sphere.
Since the displacement meter 9 is disposed around the outer peripheral surface of the weight 8, and the probe of the displacement meter 9 abuts on the surface of the weight 8. During the measurement process, if the displacement amount of the tower exists, the outer peripheral surface of the weight 8 and the probe slide relatively, and the outer peripheral surface of the weight 8 is optimally selected to be spherical and smooth in order to prevent the numerical value measured by the displacement meter 9 from generating sudden change and protecting the probe.
The tower displacement monitoring device further comprises a signal transmission mechanism 12, the signal transmission mechanism 12 is electrically connected with the displacement measuring mechanism, and the signal transmission mechanism 12 can collect and transmit the displacement measured by the displacement measuring mechanism to a data analysis place in real time.
Because the quantity of the towers is large, and the distance is long, in order to more efficiently detect the towers in a large range, a signal transmission mechanism 12 needs to be installed on each tower displacement monitoring device, and the numerical values measured by the displacement measurement mechanisms on each tower displacement monitoring device are collected and transmitted to a data analysis position through the signal transmission mechanism 12, so that the efficiency is improved, and the labor is saved.
Second embodiment
The present embodiment provides a tower displacement monitoring device, which improves the structure of the suspension mechanism 2 on the basis of the first embodiment, as shown in fig. 2.
In this embodiment, the suspension mechanism 2 further includes an elastic member 6, the connecting member 5 includes a first connecting rod 3 and a second connecting rod 4 disposed up and down, and two ends of the elastic member 6 are respectively connected to the first connecting rod 3 and the second connecting rod 4.
In order to ensure safety and prevent the occurrence of tower collapse accidents, the reason and the occurrence process of the tower collapse accidents need to be analyzed in addition to monitoring the inclination condition of the tower, so as to prevent the occurrence of the tower collapse accidents. The connecting piece 5 in the suspension mechanism 2 is set to be the first connecting piece 5 and the second connecting piece 5 which are connected by the spring, when the tower generates sudden change displacement due to local fracture and other reasons, the shell 1 and the displacement measuring mechanism which is fixedly arranged on the shell 1 also generate sudden change displacement, and because the spring has elastic potential energy, the spherical end of the suspension mechanism 2 can keep the original state and can not generate sudden change displacement, and at the moment, the displacement measuring mechanism measures a displacement. When the tower is stable, the displacement measuring mechanism and the shell 1 are also stable, and the suspension mechanism 2 is not in a vertical state, so that the tower performs pendulum motion under the action of gravity and gradually returns to the vertical state. The displacement value measured by the displacement measuring mechanism is periodically repeated and gradually approaches a stable value. The process of the tower collapse accident can be obtained by analyzing the change of the displacement measured by the displacement measuring mechanism, and the accident reason can be analyzed.
Further, the suspension mechanism 2 further includes a protection sleeve 7 sleeved outside the elastic member 6.
In order to protect the elastic part 6, the protective sleeve 7 is sleeved outside the elastic part 6, so that the service life of the suspension mechanism 2 is prolonged, the maintenance frequency is reduced, the labor is saved, and the cost is reduced.
Third embodiment
The embodiment provides a pole tower displacement monitoring device, which is further improved on the basis of the second embodiment and can detect whether the fixation of the shell 1 is loosened.
As shown in fig. 1, in the present embodiment, a vibration generating mechanism is mounted on a housing 1, and includes a motor and a rotating member 10, the motor is disposed on the housing 1, and the rotating member 10 is connected to an output shaft of the motor and eccentrically disposed, and can be driven by the motor to rotate and generate vibration.
When the tower displacement monitoring device monitors that the tower is displaced, rechecking is needed, and whether the tower inclines or the tower displacement monitoring device is loosened during the displacement is determined. When the checking is needed, the data displayed by the displacement measuring mechanism is recorded and is the initial data, then the motor is turned on to rotate the rotating member 10, and the rotating member 10 has periodic vibration because the rotating member 10 is eccentrically arranged relative to the rotating shaft. And after the motor is turned off and the device is stabilized, recording the data displayed by the displacement measuring mechanism as termination data. Even if there may be a change in the value during the vibration, just because the amplitude is transmitted to the suspension means 2 via the tower displacement monitoring device, this minor vibration is also detected due to the high sensitivity of the displacement meter 9. If the initial data is inconsistent with the termination data, it is indicated that the tower displacement monitoring device generates displacement relative to the tower under the action of vibration, and the device is loosened, and the tower inclination data monitored before may be generated due to the looseness of the device and needs to be further analyzed. However, if the initial data is consistent with the termination data, it is indicated that the tower displacement monitoring device does not generate displacement relative to the tower under the action of vibration, and the tower inclination data monitored before is real and effective.
Further, a vibration amplification mechanism 11 is mounted on the housing 1, and the rotor 10 can periodically strike the vibration amplification mechanism 11.
The vibration amplification mechanism 11 amplifies the amplitude generated by the vibration generation mechanism, so that whether the tower displacement monitoring device is loosened or not can be detected more effectively, and the influence on data analysis due to too small vibration is prevented.
Preferably, the vibration amplification mechanism 11 is a rod-shaped object with one end being spherical and the other end being rotatably connected to the housing 1.
When the rotating part 10 strikes a rod-shaped part, the amplitude is enlarged through the striking, the free end of the vibration amplification mechanism 11 is spherical, the center of gravity of the mechanism deviates to the outer end, the amplitude is further enlarged, and whether the tower displacement monitoring device is loosened or not can be effectively detected.
The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description of the present invention, which should be interpreted as a limitation.
