Description

Technical Field

[0001] The invention belongs to the field of engineering detection (monitoring), and discloses a remote control device and method for automatic sensor shedding. Background Art

[0002] In the field of engineering inspection (monitoring), there are many critical inspection (monitoring) projects, all of which rely on accurate and reliable monitoring sensors to provide key data. Take the static load test of a bridge as an example. This test is of great significance for evaluating the structural performance and bearing capacity of the bridge. When conducting such tests, technicians usually need to carefully install strain gauges and crack gauges at the bottom of the bridge (especially when cracks have appeared on the bridge) in order to monitor the strain and crack development of the bridge under stress in real time.

[0003] However, in actual operation, the installation and removal of sensors often face considerable challenges. Due to the special structure of the bridge and the height limitation, it is usually difficult for technicians to directly access the installation position at the bottom of the bridge, so they have to rely on professional equipment such as bridge inspection vehicles to assist. As an aerial work platform, the bridge inspection vehicle can easily deliver technicians to the bottom of the bridge, thereby ensuring that the sensors can be accurately and firmly installed in place.

[0004] However, the rental fee of bridge inspection vehicles is often very expensive, which is undoubtedly a considerable expense for engineering inspection projects. In particular, in some cases, when the sensors have completed their monitoring tasks, renting a bridge inspection vehicle again just to remove them will obviously greatly increase the cost burden of the project. Therefore, how to reduce the cost of sensor installation and removal has become a key issue that needs to be solved in the field of engineering inspection. Summary of the invention

[0005] In view of the above problems, the present invention discloses a remote control device and method for automatically removing sensors, which can automatically remove all sensors with one click through the remote control, thereby achieving the effect of remote and rapid removal of sensors.

[0006] The technical solution of the present invention is as follows:

[0007] A remote control device for automatic sensor shedding, comprising a mounting support, a heating device, a cloth belt ring, a bolt, and a sensor

[0008] The mounting support comprises a base and a clamp; the base has two circular holes, the clamp is two parallel flat plates, each of the two flat plates has a circular hole at the lower end, and the circular hole of one of the flat plates has an internal thread; the inner side of the clamp is a rough surface, and there is an anti-slip device in the middle;

[0009] The cloth belt loop is sleeved on the bottom of the clamp;

[0010] The bolts can be inserted into the two circular holes of the clamp;

[0011] The heating device is arranged on the mounting support, and its heating part is close to the cloth belt ring;

[0012] The sensor is clamped in a fixture of the mounting support.

[0013] Furthermore, in the above-mentioned remote control device for automatic sensor detachment, the heating device includes a battery, a wire, and a resistance heating rod, wherein the resistance heating rod is fixed to the outside of the clamp of the mounting support and can be located at a position that can be covered by a cloth belt ring.

[0014] Furthermore, in the above-mentioned sensor automatic detachment remote control device, the heating device is also provided with a wireless control switch and a separate remote controller.

[0015] Furthermore, in the above-mentioned remote control device for automatic sensor detachment, the cloth belt ring is an annular cloth belt with strong tensile strength and easy to break at high temperature.

[0016] Furthermore, in the above-mentioned sensor automatic detachment remote control device, the cloth belt ring is made of nylon.

[0017] Furthermore, in the above-mentioned sensor automatic detachment remote control device, a cable is also provided on the sensor.

[0018] Furthermore, in the above-mentioned sensor automatic detachment remote control device, there are two circular holes on the base for fixing the mounting bracket on the structure.

[0019] The present invention also discloses a remote control method for automatic sensor shedding, the steps of which are as follows:

[0020] (1) Clamp the sensor into the fixture of the mounting bracket;

[0021] (2) Tighten the bolts. At this time, the bottoms of the two flat plates of the fixture for mounting the support will continue to move closer to each other under the action of pressure;

[0022] (3) Put the cloth belt loop on the bottom of the fixture of the mounting bracket;

[0023] (4) Unscrew the bolts. At this time, due to the action of the cloth belt ring, the clamp still has enough pressure to clamp the sensor;

[0024] (5) For each sensor, install a mounting bracket at each end, and then fix the mounting bracket to the structure using glue or expansion bolts;

[0025] (6) After the detection (monitoring) is completed, press the remote control switch, the wireless control switch is closed, the resistance heating rod heats up and fuses the cloth belt ring, so that the fixture of the mounting bracket releases the sensor, the sensor will automatically fall off, and then the sensor can be recovered by pulling the cable on the sensor.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] The sensor automatic detachment remote control device proposed in the present invention integrates key components such as mounting bracket, heating device, specially designed cloth belt ring, bolts and sensor, and realizes remote intelligent operation of sensor installation and removal. Its beneficial effects are mainly reflected in the following aspects:

[0028] Significant cost reduction: The sensor can be automatically detached with one-touch control through the remote control, avoiding the need for high-altitude operations with the help of bridge inspection vehicles or aerial platforms in traditional methods, thereby greatly reducing the cost of equipment rental and manual operation. The cost saving effect is particularly significant for engineering projects that require frequent installation and removal of sensors.

[0029] Improve operational safety: The implementation of remote control reduces the risk of personnel working directly at high altitudes or in complex environments, effectively ensures the safety of operators, and reduces the probability of safety accidents.

[0030] Improve work efficiency: The sensor removal process is completed by remote control, which is simple and quick to operate, greatly shortening the disassembly time and improving the overall work efficiency, especially in large-scale monitoring projects, which can quickly complete the deployment and recovery of sensors.

[0031] Enhanced applicability: The device is cleverly designed and compactly structured, making it suitable for a variety of environments that are difficult to directly access, such as the bottom of bridges and the exterior walls of high-rise buildings. This broadens the application range of the sensor and makes monitoring work more flexible and efficient.

[0032] Promote intelligent development: Through the application of wireless control technology, this device promotes the intelligent process in the field of engineering detection, and provides a technical basis and demonstration cases for future remote monitoring, intelligent maintenance, etc.

[0033] In summary, the present invention not only excels in economy, safety and efficiency, but also promotes the development of engineering technology towards a more intelligent and convenient direction, and has broad application prospects and important practical value.
