Description

Technical Field

[0001] The present invention relates to a monitoring device, in particular to a monitoring device for a subway tunnel. Background Art

[0002] Subway projects are often built in underground rock and soil, subject to complex engineering geology and hydrogeology, which are subject to numerous uncertainties. Over time, due to other factors, tunnels can experience problems such as excessive settlement, necessitating repairs. Conventional tunnel settlement monitoring requires setting up observation points every 20-30 meters. This requires personnel to carry equipment into the tunnel to observe and determine whether and to what extent tunnel operations are being impacted. This method is cumbersome.

[0003] Publication number CN202928559U discloses a device for observing the settlement of a subway tunnel, including an inclinometer tube and a horizontal inclinometer. The inclinometer tube is provided with a guide groove with a fixed direction, and the horizontal inclinometer is equipped with a guide wheel, which is snapped into the guide groove of the inclinometer tube. The device does not require personnel to move inside the tunnel for observation and is simple to operate. However, personnel cannot monitor the conditions inside the tunnel in real time, and the results obtained by relying solely on the data obtained by the device for analysis will still be subject to errors.

The first dual-axis motor 103 is provided on the second bracket 102. Winding wheels 104 are provided on the output shafts on both sides of the first dual-axis motor 103. A pull rope 105 is connected between the winding wheels 104 and the slider 4. A first spring 106 is connected between the rear side of the slider 4 and the rear side of the track 3. The first spring 106 is located on the inner side of the track 3.

[0094] Reference Figure 8The monitoring mechanism 11 includes a third bracket 111, a second support bracket 112, a second dual-axis motor 113, a first camera 114, a third support bracket 115 and a second distance sensor 116. Two third brackets 111 are provided on the lower side of the slider 4. The two third brackets 111 are symmetrically arranged on the left and right. A second support bracket 112 is provided between the lower rear side of the third bracket 111, and a second dual-axis motor 113 is provided in the middle of the second support bracket 112. The output shafts on both sides of the second dual-axis motor 113 are rotatably connected to the third bracket 111 on the same side. The output shafts on both sides of the second dual-axis motor 113 are provided with a first camera 114. A third support bracket 115 is provided on the front side of the second support bracket 112, and a second distance sensor 116 is provided in the middle of the front side of the third support bracket 115.

[0095] When using this device, install it on the inside of the subway tunnel, press the main power switch to power on the device, and in the initial state, the first spring 106 is stretched. First, use a tool to approach the second distance sensor 116. The second distance sensor 116 detects that the distance between the tool and the second distance sensor 116 reaches a preset value. The control module controls the output shafts on both sides of the second dual-axis motor 113 to rotate forward one hundred and eighty degrees and then stop. The output shafts on both sides of the second dual-axis motor 113 rotate forward to drive the first camera 114 to rotate forward, so that the first camera 114 can shoot the top of the tunnel, so that the staff can clearly observe the situation of the sinking position of the tunnel through the first camera 114, and then press the touch switch 101. The control module controls the output shaft of the first dual-axis motor 103 to rotate forward fifteen circles and then stop. After fifteen turns of reverse rotation, it is closed, the output shaft of the first dual-axis motor 103 rotates forward to drive the winding wheel 104 to rotate forward, the pull rope 105 is loosened, and then the slider 4 is driven to move backward under the action of the first spring 106 reset, and the slider 4 drives the first bracket 5, the first distance sensor 6, the electric push rod 7, the contactor 8, the signal transmission module 9, the third bracket 111, the second support bracket 112, the second dual-axis motor 113, the first camera 114, the third support bracket 115 and the second distance sensor 116 to move backward. After fifteen turns of forward rotation, the output shaft of the first dual-axis motor 103 is reversed to drive the winding wheel 104 to reverse, and the pull rope 105 is retracted, and then the slider 4 is driven to move forward and reset through the pull rope 105, and the slider 4 drives the first bracket 5, the first distance sensor The device 6, the electric push rod 7, the contactor 8, the signal transmission module 9, the third bracket 111, the second support frame 112, the second dual-axis motor 113, the first camera 114, the third support frame 115 and the second distance sensor 116 move forward and reset. If the distance between the first distance sensor 6 and the top of the tunnel does not change during the movement, it means that the tunnel has not sunk. When the first distance sensor 6 detects that the distance between it and the top of the tunnel reaches a preset value during the movement, it means that there may be a risk of tunnel sinking. The control module controls the first dual-axis motor 103 to stop running. At the same time, the control module controls the electric push rod 7 to extend the telescopic rod for one second and then stop. The extension of the telescopic rod of the electric push rod 7 drives the contactor 8 to move downward, so that The contactor 8 is inserted into the signal transmission module 9, so that the signal transmission module 9 transmits the signal to the receiving signal, thereby reminding the staff. The staff monitors the top condition of the tunnel through the first camera 114. After the tunnel is surveyed and there is no problem, the touch switch 101 is pressed again. The control module controls the output shafts on both sides of the second dual-axis motor 113 to reverse 180 degrees and then turn off. The output shafts on both sides of the second dual-axis motor 113 reverse and drive the first camera 114 to reverse and reset. At the same time, the control module controls the output shaft of the first dual-axis motor 103 to reverse and reset. The output shaft of the first dual-axis motor 103 reverses and drives the winding wheel 104 to reverse, retract the pull rope 105, and then drive the slider 4 to move forward and reset through the pull rope 105. The first spring 106 is stretched.The slider 4 drives the first bracket 5, the first distance sensor 6, the electric push rod 7, the contactor 8, the signal transmission module 9, the third bracket 111, the second support bracket 112, the second dual-axis motor 113, the first camera 114, the third support bracket 115, and the second distance sensor 116 to move forward and reset. The control module also controls the electric push rod 7 to retract for one second and then turn off. The retraction of the electric push rod 7 drives the contactor 8 to move upward and reset. When the device is not in use, press the main power switch to turn off the power.

[0098] When the telescopic rod of the electric push rod 7 is extended, the baffle 121 is driven to move downward, so that the baffle 121 contacts the photoelectric sensor 122. The photoelectric sensor 122 detects that the light becomes darker and reaches a preset value. The control module controls the output shaft of the drive motor 124 to rotate for five seconds and then turns off. The output shaft of the drive motor 124 rotates to drive the disc 125 to rotate, and then drives the sliding block 127 to move back and forth. The sliding block 127 drives the brush 128 to move back and forth, so that when the brush 128 contacts the first camera 114, it brushes the first camera 114 to prevent dust from sticking to the first camera 114, resulting in blurred images. At the same time, when the sliding block 127 moves backward and contacts the second distance sensor 116, the second distance sensor 116 detects that the distance between it and the sliding block 127 reaches a preset value. After a delay of five seconds, the control module controls the output shafts on both sides of the second dual-axis motor 113 to rotate forward 180 degrees and then stop. In this way, people do not need to use tools to make the second distance sensor 116 perform detection.

When the photoelectric sensor 122 detects that the light becomes darker and reaches a preset value, the control module controls the water pump 135 to start and then shut down after five seconds. The water pump 135 draws the water in the water tank 132 into the pipe 137 through the hose 136, and then flows out through the brush 128, thereby wetting the brush 128, so that the brush 128 can clean the first camera 114 more cleanly.
