Description
Technical Field
[0001] This utility model relates to the technical field of slope landslide monitoring, and in particular to a slope instability monitoring device. Background Technology
[0002] As we all know, in order to understand the movement of slopes and detect early signs of slope failure, it is necessary to monitor and warn of slope displacement; especially for slopes on both sides of roads, landslides often cause significant personal and property losses.
[0003] For example, utility model patent application CN202057311U discloses a slope monitoring device, including a fixed base connected to an aiming device via a screw. The fixed base consists of a rod connecting a second steel plate, and the aiming device consists of an L-shaped protective component and a prism, with the prism mounted on the L-shaped protective component. This device is highly practical for monitoring high and steep slopes, improving work efficiency while ensuring measurement accuracy.
[0004] However, the above-mentioned device still has the following drawbacks: it can only achieve single monitoring of the slope, and it is difficult to achieve continuous monitoring of the slope. If a small landslide occurs on the slope, it is not easy for patrol personnel to detect it, which has certain limitations in its use. Utility Model Content
[0005] In view of the shortcomings of the existing technology, this utility model provides a slope instability monitoring device that can continuously monitor slopes, improve monitoring accuracy, and provide effective early warning of slope landslides.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a slope instability monitoring device, comprising a slope, an early warning monitoring mechanism, and a light emitting mechanism. The early warning monitoring mechanism is installed on the upper part of the slope, specifically on the inclined surface of the slope. The light emitting mechanism includes a first frame and a laser light mounted on the first frame. The first frame is arranged perpendicular to the inclined surface of the slope. The early warning monitoring mechanism includes a second frame, a dark box mounted on the second frame, a photoresistor, a control circuit board, a power supply, and an early warning light. The second frame is arranged parallel to the first frame. The photoresistor, control circuit board, and power supply are all installed inside the dark box. The dark box has a light-transmitting hole corresponding to the photoresistor. The power supply, early warning light, control circuit board, and photoresistor are electrically connected. The laser beam emitted by the laser light illuminates the photoresistor through the light-transmitting hole. Further, a storage battery is preferably used as the power supply. Further, the control circuit board includes circuits, resistors, and transistors.
[0007] Preferably, the light emitting mechanism is in multiple sets, and the multiple sets of light emitting mechanisms are evenly distributed from top to bottom along the inclined slope of the slope. The photoresistors are in multiple sets, and the multiple sets of photoresistors are evenly distributed from top to bottom in the dark box. The laser beams emitted by the laser lamps on the multiple sets of light emitting mechanisms respectively irradiate the corresponding photoresistors.
[0008] Preferably, there are multiple early warning monitoring mechanisms, and multiple early warning monitoring mechanisms and multiple sets of light emitting mechanisms are evenly distributed laterally along the inclined slope surface; further, multiple light emitting mechanisms are arranged in a matrix on the slope surface, and multiple early warning monitoring mechanisms are used to receive laser beams emitted by laser lights on multiple light emitting mechanisms in the same vertical row.
[0009] Preferably, it also includes a signal transmitter connected in series with the warning light, the signal transmitter being used to transmit slope landslide information outward; furthermore, the signal transmitter is fixedly installed on the second frame, and the signal transmitter can be an equivalent transmitter with signal long-distance transmission effect, such as an RF (radio frequency) signal transmitter, an audio (AF) signal transmitter, or a baseband signal transmitter.
[0010] Preferably, both the first frame and the second frame include a base frame and a telescopic frame, wherein the telescopic frame is slidably mounted on the base frame, and the telescopic frame and the base frame are engaged by bolts.
[0011] Preferably, the base frame is provided with a through hole, and an anchor bolt is installed at the through hole, and the base frame is fixedly connected to the slope by the anchor bolt.
[0012] Preferably, an orientation adjuster is installed on the top of the first frame. The orientation adjuster includes a fixed base, a rotating base hinged to the fixed base, and a support base rotatably installed on the rotating base. The rotating base and the fixed base are locked together by bolts, and the support base is locked together with the rotating base by bolts. The laser lamp is fixedly installed on the support base.
[0013] Preferably, a sunshade is provided at the light-transmitting hole of the dark box; the sunshade is used to block sunlight and other light from entering the dark box.
[0014] Compared with the prior art, this utility model provides a slope instability monitoring device with the following beneficial effects: In the initial state, the laser beam emitted by the laser lamp on the light emitting mechanism is parallel to the inclined slope surface and illuminates the photoresistor. At this time, the resistance of the photoresistor decreases after receiving light, and the current of the power supply flows through the resistor and photoresistor on the control circuit board. In the circuit formed by the warning lamp, transistor and power supply, the transistor is in the cut-off state, and no current flows through the warning lamp. At this time, the warning lamp is in the off state. When a landslide occurs on the slope, the first frame tilts or slides down, and the far end of the laser beam emitted by the laser lamp deviates by a large distance and cannot illuminate the photoresistor. Even if the landslide range is small, it causes the laser beam emitted by the laser lamp to move over a large range, thereby improving the monitoring accuracy. When there is no laser beam, the resistance value at the photoresistor increases, the circuit of the power supply, warning lamp and transistor is connected, the warning lamp lights up and issues a warning, and the patrol personnel can promptly discover and deal with the warning location, realizing continuous monitoring of the slope and effective early warning of slope landslides.

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0024] As described in the background section, the slope monitoring device can only perform single-time monitoring of the slope and is difficult to perform continuous monitoring of the slope.

The early warning monitoring mechanism 2 includes a second frame, a dark box 5 installed on the second frame, a photoresistor 6, a control circuit board 7, a power supply 8, and an early warning light 9. The second frame is arranged parallel to the first frame. The photoresistor 6, the control circuit board 7, and the power supply 8 are all installed inside the dark box 5. The dark box 5 is provided with a light-transmitting hole 10 corresponding to the photoresistor 6. The power supply 8, the early warning light 9, the control circuit board 7, and the photoresistor 6 are electrically connected. The laser beam emitted by the laser light 4 shines on the photoresistor 6 through the light-transmitting hole 10. Furthermore, the power supply 8 is preferably a storage battery; furthermore, the control circuit board 7 is equipped with circuitry, resistor 19, and transistor 20. For a detailed circuit diagram of this slope instability monitoring device, please refer to [reference needed]. Figure 7 The positive terminal of power supply 8 is connected to the collector of transistor 20 through warning light 9. The emitter of transistor 20 is connected to the negative terminal of power supply 8. The base of transistor 20 is also connected to the positive terminal of warning light 9 through resistor 19. One end of photoresistor 6 is connected to resistor 19 and the base of transistor 20. The other end of photoresistor 6 is connected to the collector of transistor 20 and the negative terminal of power supply 8.
[0028] Specifically, it also includes a signal transmitter 11 connected in series with the warning light 9. The signal transmitter 11 is used to transmit landslide information from the slope 1 outward. Furthermore, the signal transmitter 11 is fixedly installed on the second frame. The signal transmitter 11 can be an equivalent transmitter with signal long-distance transmission effect, such as an RF radio frequency signal transmitter, an audio AF signal transmitter, or a baseband signal transmitter.
[0029] Specifically, both the first frame and the second frame include a base frame 12 and a telescopic frame 13. The telescopic frame 13 can be slidably installed on the base frame 12, and the telescopic frame 13 and the base frame 12 are engaged by bolts.
[0030] Specifically, the base frame 12 is provided with a through hole, and an anchor bolt 14 is installed at the through hole. The base frame 12 is fixedly connected to the slope 1 through the anchor bolt 14.
[0031] Specifically, an orientation adjuster is installed on the top of the first frame. The orientation adjuster includes a fixed base 15, a rotating base 16 hinged to the fixed base 15, and a support base 17 rotatably mounted on the rotating base 16. The rotating base 16 and the fixed base 15 are locked together by bolts, and the support base 17 is locked together with the rotating base 16 by bolts.

[0032] Specifically, a sunshade 18 is provided at the light-transmitting hole 10 of the dark box 5; the sunshade 18 is used to block sunlight and other light from entering the dark box 5.
[0033] The slope instability monitoring device provided in this embodiment, when the circuit at the warning light 9 is connected, the signal transmitter 11 and the power supply 8 are connected and transmit signals outward. The monitoring personnel can receive the signals through the corresponding external signal receiving equipment, and remotely obtain the slope instability information of the slope 1, so as to deal with the instability of the slope 1 in a timely manner. By adjusting the extension of the telescopic frame 13 at the base frame 12, the installation height of the laser lamp 4 and the photoresistor 6 can be adaptively adjusted to ensure that the laser emitted by the laser lamp 4 accurately illuminates the photoresistor 6. After the height adjustment is completed, the telescopic frame 13 and the base frame 12 are secured with bolts. The base frame 12 can be fixedly anchored to the slope 1 by anchor bolts 14 to improve the installation stability of the monitoring device, so that the monitoring device is integrated with the slope 1. When the slope 1 shifts, the corresponding light emitting mechanism 3 shifts synchronously. The orientation adjuster can adaptively adjust the up-down and left-right orientation of the laser lamp 4 so that the laser beam emitted by the laser lamp 4 is aligned with the corresponding photoresistor 6. The sunshade 18 can prevent external sunlight from shining into the photoresistor 6 and avoid interference from natural light on the photoresistor 6.
[0034] Example 2
[0035] The slope instability monitoring device provided in Example 1 has been further optimized. For details, please refer to... Figures 1-7The light emitting mechanism 3 consists of multiple sets, which are evenly distributed from top to bottom along the inclined slope of the slope 1. The photoresistors 6 also consist of multiple sets, which are evenly distributed vertically within the dark box 5. The laser beams emitted by the laser lamps 4 on the multiple sets of light emitting mechanisms 3 illuminate the corresponding photoresistors 6.
[0036] Specifically, there are multiple early warning monitoring units 2, and multiple early warning monitoring units 2 and multiple sets of light emitting units 3 are evenly distributed laterally along the inclined slope surface of the slope 1; further, multiple light emitting units 3 are arranged in a matrix on the slope surface, and multiple early warning monitoring units 2 are used to receive the laser beams emitted by the laser lights 4 on the multiple light emitting units 3 in the same vertical row; the distance between two adjacent light emitting units 3 can be a standard distance such as 0.5m or 1m.
[0037] The slope instability monitoring device provided in this embodiment has multiple sets of light emitting mechanisms 3 arranged in rows to monitor the vertical direction of the slope 1 as a whole, while multiple sets of light emitting mechanisms 3 arranged in a matrix can monitor the entire slope 1 comprehensively, greatly improving the monitoring range of the slope 1.
[0038] The operation of the slope instability monitoring device provided by this utility model is as follows: In the initial state, the laser beam emitted by the laser lamp 4 on the light emitting mechanism 3 is parallel to the inclined slope surface of the slope 1 and illuminates the photoresistor 6. At this time, the resistance of the photoresistor 6 decreases after receiving light, and the current of the power supply 8 flows through the resistor 19 on the control circuit board 7 and the photoresistor 6. In the circuit formed by the warning lamp 9, the transistor 20 and the power supply 8, the transistor 20 is in the cut-off state, and no current flows through the warning lamp 9. At this time, the warning lamp 9 is in the off state. When a landslide occurs on the slope 1, the first... If a structure tilts or slides, even if the landslide area is small, it will cause the laser beam emitted by laser light 4 to move over a large area to improve monitoring accuracy. After the far end of the laser beam emitted by laser light 4 is deflected by a large distance, it will not be able to illuminate the photoresistor 6. When there is no laser beam, the resistance value of the photoresistor 6 increases, and the circuits of power supply 8, warning light 9 and transistor 20 are connected. The warning light 9 lights up and issues a warning, and the signal transmitter 11 can also send relevant information to the external monitoring receiving equipment so that the monitoring personnel can discover and deal with the warning location in time.
