Description

Technical Field

[0001] The present application relates to the technical field of goaf monitoring equipment, and in particular to a goaf monitoring probe protection device for expressways. Background Art

[0002] The goaf of a highway refers to an empty space that is specially designed during the construction of a highway to avoid affecting the mining of existing mineral resources. The goaf is formed by underground cavities caused by mineral mining, and there may be hidden dangers of geological disasters. In order to avoid the impact of these geological disasters on the highway, continuous monitoring is required. Due to the complexity of the goaf environment, the monitoring probe needs to be protected to ensure the reliability and accuracy of its data collection.

[0003] In the prior art, a geological probe is generally used to monitor the goaf of a highway, which includes a probe body 16, a probe 17 installed at the bottom of the probe body 16, and a sensor 18 installed at the bottom of the probe 17. During installation, the sensor 18 needs to be in contact with the ground to collect data. When this probe is in use, a protective cover is generally provided on the outside to protect it. However, as for the material of the protective cover, using a transparent material may change the contact mode between the probe and the ground or the input of the sensor measurement, thereby affecting the accuracy of the data. When an opaque material is used, if the probe works in an environment with strong ultraviolet radiation, this protective cover cannot block ultraviolet radiation, and ultraviolet radiation on the sensor affects its operation. In some areas, the sun is too strong during the day and the ultraviolet radiation is strong. The prior art cannot meet the use needs of the above-mentioned areas. Therefore, a highway goaf monitoring probe protection device is proposed to solve the above-mentioned problems. Utility Model Content

An installation groove is provided on the upper surface of the base 2, and the inner bottom wall of the installation groove is fixedly connected to a motor 8. A connecting rod 9 is fixedly connected to the output end of the motor 8, and the end of the connecting rod 9 away from the motor 8 is fixedly connected to the strong magnetic block 7. The connecting rod 9 is driven to rotate by the output end of the motor 8, and then the strong magnetic block 7 is driven to rotate. By setting the strong magnetic block 7 to drive the movable card 6 to move along the slide groove, the outer protective layer 4 can be unfolded or retracted.

[0031] The material of the outer protective layer 4 is black cloth, and the material of the outer protective layer 4 is preferably black cloth, which is used to shield the protective cover 3.

[0032] The protective cover 3 includes a first cover body 301 and a second cover body 302. The first cover body 301 and the second cover body 302 are both semicircular arc surfaces. When the first cover body 301 and the second cover body 302 are closed, they protect the monitoring probe 1. The bottom ends of the first cover body 301 and the second cover body 302 are fixedly connected with a sealing strip 303. The first cover body 301 and the second cover body 302 are both made of transparent plastic.

[0037] Working principle: When the highway goaf area monitoring probe 1 protection device is used, the user first uses the mounting plate 15 to install the monitoring probe 1. When in use, the protective cover 3 can prevent the ultraviolet sound sensor 18 from working during the day, and the sealing strip 303 is used to prevent external dust from entering the protective cover 3 and affecting the work of the monitoring probe 1. The limit plate 12 that can slide up and down can be used to change the length of the protective cover 3 extending out of the limit slot to ensure that the sensor 18 of the monitoring probe 1 can directly contact the ground. When the ultraviolet rays are not strong, the motor 8 is started, and the output of the motor 8 is The output end drives the connecting rod 9 to rotate, the connecting rod 9 drives the strong magnetic block 7 to rotate, the strong magnetic block 7 drives the movable card 6 to move along the slide groove, and the movable card 6 drives the outer protective layer 4 to unfold. After unfolding, the outer protective layer 4 shields the protective cover 3 to prevent the protective cover 3 from changing the contact mode between the monitoring probe 1 and the ground or the input measured by the sensor 18. When the monitoring probe 1 needs to be inspected or replaced, loosen the fastening bolts and move the first cover body 301 to the back, and open the protective cover 3, so that the protection device of the highway goaf monitoring probe 1 can meet the use requirements.
