Description

Technical Field

[0001] The present invention relates to the field of slope monitoring, and particularly to a monitoring and alarm device for preventing slope geological disasters. Background Art

[0002] A slope monitoring and alarm device is a device used to monitor the stability of slopes in real time and issue alarms in a timely manner. Slope geological disasters (such as landslides, collapses, etc.) pose a serious threat to the safety of people's lives and property. Therefore, it is necessary to install a monitoring and alarm device to detect and warn of potential risks in a timely manner. The general process of installing a monitoring and alarm device on an existing slope is as follows: First, select a suitable installation location on the slope to pour a foundation that penetrates deep into the ground. Then, install the monitoring and alarm device on the foundation and adjust the tilt angle of the video monitoring module of the monitoring and alarm device so that the shooting range of the video monitoring module fully covers the slope surface. If there are falling rocks or landslides on the slope, the monitoring and alarm device will issue an alarm.

[0003] During the installation process of the existing monitoring and alarm device, if the surface of the poured foundation is uneven, the monitoring and alarm device installed on the foundation will be in an inclined state, and the inclination angle of the monitoring and alarm device is uncertain. The inclination angle of the video monitoring module in the monitoring and alarm device cannot be accurately judged, so that the shooting range of the video monitoring module is likely to deviate, resulting in some areas of the slope surface not being monitored, increasing the potential risk of slope landslides and posing a safety hazard to surrounding residents and facilities.

DETAILED DESCRIPTION OF THE INVENTION

[0030] The following combines the attached Figure 1 - attached Figure 10, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0031] Example 1: During the installation of the existing monitoring and alarm device, if the surface of the base is uneven, the monitoring and alarm device will be tilted at a certain angle when it is installed on the base, making it impossible to quickly determine the tilt angle of the video shooting module in the monitoring and alarm device. It is easy for the monitoring range of the video shooting module to fail to fully cover the slope surface, making it impossible to monitor some areas of the slope surface, increasing the risk of potential slope landslides and posing a safety hazard to surrounding residents and facilities.

[0032] A monitoring and alarm device for preventing and controlling geological disasters on slopes, please refer to the attached Figure 1 -Attached Figure 8 As shown, it includes: a mounting shell 1, on which a rotating frame 2 is rotatably connected, and the rotating frame 2 is limitedly and slidably connected to a connecting column 3, and a variety of modules are arranged on the connecting column 3 for monitoring a variety of data of the slope; two limit blocks 4, which are slidably connected in the connecting column 3, and a spring is fixedly connected between the limit block 4 and the connecting column 3, and the rotating frame 2 is provided with two blind holes, and the limit block 4 is limitedly matched with the blind holes of the rotating frame 2; a knob 5, which is rotatably connected to the rotating frame 2, and a damping is arranged between the knob 5 and the rotating frame 2, and the knob 5 is fixedly connected to a fixed block 6, and the rotating frame 2 is rotatably connected to a weight block 7, and the fixed block 6 is provided with a pressure sensing sheet that is pressed and matched with the weight block 7, and is used to set the inclination angle of the connecting column 3; an angle locking mechanism, which is arranged on the rotating frame 2, and is used to make the mounting shell 1 and the rotating frame 2 relatively fixed. Fixed; a protection mechanism is arranged in the mounting shell 1, and is used to protect the module on the connecting column 3. The contact surfaces of the mounting shell 1 and the rotating frame 2 are both spherical surfaces, which are used to ensure that the mounting shell 1 is always in a closed state during the rotation of the rotating frame 2. The angle locking mechanism includes: a hydraulic cylinder 201, which is rotatably connected to the mounting shell 1, and the hydraulic cylinder 201 is connected to a liquid guide tube 202. A liquid storage cylinder 203 is fixedly connected in the mounting shell 1, and the liquid storage cylinder 203 is connected to the liquid guide tube 202. A sliding plate 204 is sealed and slidably connected at the connection between the liquid guide tube 202 and the liquid storage cylinder 203. The sliding plate 204 is provided with a through hole that is connected to the liquid guide tube 202, and is used to relatively fix the mounting shell 1 and the rotating frame 2; an electric push rod 205, which is fixed in the mounting shell 1, and the telescopic end of the electric push rod 205 is fixedly connected to the sliding plate 204.

[0033] In the above solution, it aims to solve the problem that when the surface of the base is inclined, the inclination angle of the video shooting module of the monitoring and alarm device installed on the base cannot be accurately adjusted. The rotating frame 2 is located at the upper part of the installation shell 1. The installation shell 1 is provided with a solar panel and a control box. The module on the connecting column 3, the pressure sensing piece on the fixed block 6 and the angle locking mechanism are all electrically connected to the control box. The module on the connecting column 3 includes: a sensor module, a communication module, an alarm module, a video monitoring module, etc. The sensor module installs different types of sensors according to monitoring requirements, such as displacement sensors, stress and strain sensors, hydrological sensors, etc. The center of the spherical surface of the rotating frame 2 is located on its rotation axis, so that the installation shell 1 remains sealed during the rotation of the rotating frame 2, preventing external impurities from entering the installation shell 1 and corroding the parts inside the device. A notch is provided at the position on the installation shell 1 to the right of the rotating frame 2, and the width of the notch is equal to the width of the connecting column 3, so that the connecting column 3 can smoothly enter the installation shell 1 as the rotating frame 2 rotates. Due to the damping between the knob 5 and the rotating frame 2, the knob 5 rotates relative to the rotating frame 2 only when manually rotated, which is convenient for setting the inclination angle of the connecting column 3 (the set inclination angle is calculated in advance by the operator according to the inclination angle and area of the slope, combined with the position of the monitoring and alarm device installed at the lower part of the slope, so that the device can comprehensively monitor the surface of the slope after installation). The included angle between the fixed block 6 and the heavy object block 7 is equal to the inclination angle of the video monitoring module in the device. Initially, the liquid guide pipe 202 and the liquid storage cylinder 203 are communicated through the through hole of the sliding plate 204, and the telescopic end of the hydraulic cylinder 201 can freely expand and contract. Through the cooperation of the through hole of the sliding plate 204 and the liquid guide pipe 202, the rotating frame 2 can be locked at any time during the rotation process. Through the cooperation of the fixed block 6 and the heavy object block 7, the accurate positioning of the inclination angle of the video monitoring module is completed, ensuring the comprehensiveness of the slope surface monitoring during the use of the device and reducing the possibility of potential safety hazards.

[0034] Workflow: First, the operator inserts the connecting column 3 into the rotating frame 2. The inclined surface of the limit block 4 presses the rotating frame 2, and the limit block 4 moves into the connecting column 3 and compresses the connected spring. When the limit block 4 aligns with the blind hole of the rotating frame 2, the limit block 4 moves under the elastic force of the connected spring and inserts into the blind hole of the rotating frame 2, and the connecting column 3 is fixed on the rotating frame 2. The auxiliary fixing component assists in fixing the connecting column 3 in the rotating frame 2. Subsequently, the operator rotates the knob 5 by a certain angle so that the included angle between the fixed block 6 and the heavy object block 7 is the set angle. The knob 5 drives the fixed block 6 to rotate synchronously. The heavy object block 7 is always in a vertical state under the action of gravity. Subsequently, the operator swings the connecting column 3 to the right, and the connecting column 3 drives the rotating frame 2 to rotate clockwise (viewed from front to back). The rotating frame 2 drives the fixed block 6 to rotate synchronously through the knob 5, and the telescopic end of the hydraulic cylinder 201 is pulled out, and the hydraulic cylinder 201 rotates adaptively. The hydraulic oil in the liquid storage cylinder 203 enters the hydraulic cylinder 201 through the through hole of the sliding plate 204 and the liquid guide pipe 202.

[0035] During the rotation of the rotating frame 2, if the pressure sensing piece on the fixed block 6 contacts the weight block 7, the inclination angle of the video monitoring module on the connecting column 3 is the set angle, and the pressure sensing piece feeds back a signal to the control box, which starts the electric push rod 205, and the telescopic end of the electric push rod 205 extends and drives the sliding plate 204 to move forward. The through hole on the sliding plate 204 is misaligned with the liquid guide tube 202, and the liquid guide tube 202 is blocked. The telescopic end of the hydraulic cylinder 201 stops moving, and the mounting shell 1 and the rotating frame 2 are relatively locked. At this point, all installation operations of the device are completed. The device monitors the slope, and performs emergency alarm processing when rockfall or landslide occurs on the slope, alerts nearby personnel, and ensures the life safety of nearby personnel. After the device is used for a long time, if the module on the connecting column 3 fails, the operator manually moves the two limit blocks 4 closer to each other, and the limit blocks 4 compress the connected springs and move out of the blind hole of the rotating frame 2. The relatively fixed contact between the rotating frame 2 and the connecting column 3 can directly remove the connecting column 3 for maintenance.

[0036] During the use of the device, if the slope has a landslide, the operator releases the connection between the telescopic end of the hydraulic cylinder 201 and the rotating frame 2 through the protection mechanism. At the same time, the control box controls the rotating frame 2 to rotate clockwise (from front to back) through the protection mechanism. The rotating frame 2 drives the connecting column 3 into the installation shell 1 for storage protection to prevent the landslide from directly hitting the module on the connecting column 3, thereby ensuring the security of the data in the module on the connecting column 3 and facilitating the subsequent analysis by the operator based on the monitoring data.

[0037] Please refer to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 5 -Attached Figure 7 and attached Figure 9As shown in the figure, the protection mechanism includes: a motor 301 fixedly connected to the mounting shell 1. The output shaft of the motor 301 is rotatably connected to the mounting shell 1. A rotating ring 302 is rotatably connected to the upper part of the mounting shell 1. The output shaft of the motor 301 is driven by a gear and a toothed ring to be connected with the rotating ring 302; a connecting bent rod 303 is slidably connected in the rotating frame 2. The telescopic end of the hydraulic cylinder 201 is slidably and rotatably connected to the connecting bent rod 303. A spring is fixedly connected between the connecting bent rod 303 and the rotating frame 2. A fixing rod 304 is fixedly connected to the rotating ring 302. The fixing rod 304 is in extrusion fit with the connecting bent rod 303 for releasing the connection between the telescopic end of the hydraulic cylinder 201 and the rotating frame 2; a sealing assembly is arranged in the rotating frame 2 for controlling the communication state between the space in the mounting shell 1 and the outside; an auxiliary fixing assembly is arranged in the rotating frame 2 for stably fixing the connecting column 3 in the rotating frame 2 and enabling it to be quickly replaced. The sealing assembly includes: a fixing plate 401 fixedly connected to the rotating frame 2 for protecting the connecting column 3 from being extruded; two sliding baffles 402 are slidably connected to the mounting shell 1. The fixing plate 401 is in extrusion fit with the sliding baffles 402. Springs are fixedly connected between the sliding baffles 402 and the mounting shell 1. The sliding baffles 402 are used for closing the space in the mounting shell 1. The width of the fixing plate 401 gradually increases from bottom to top. The maximum width of the fixing plate 401 is greater than the maximum width of the upper part of the connecting column 3 for preventing the connecting column 3 from being extruded by the sliding baffles 402. Two inclined surfaces are arranged on the fixing plate 401. The inclined surfaces of the fixing plate 401 are in extrusion fit with the sliding baffles 402.

[0038] In the above solution, it aims to solve the problem that when a landslide occurs on the slope, it is easy to damage the monitoring and alarm device, which is not conducive to the operator to recover the monitoring data in the monitoring and alarm device. The output shaft of the motor 301 only drives the rotating ring 302 to rotate clockwise (viewed from front to back) through a gear and a toothed ring. The fixing rod 304 is an inclined rod. The inclined direction of the fixing rod 304 is upwardly inclined from back to front. After the fixing rod 304 pushes the connecting bent rod 303 into the rotating frame 2 to the limit, the front end of the connecting bent rod 303 is still located outside the spherical surface of the rotating frame 2 (attached Figure 9For the state where the fixed rod 304 and the connecting bent rod 303 are not squeezed against each other, the front part of the connecting bent rod 303 is located outside the spherical surface of the rotating frame 2. During the rotation of the fixed rod 304 with the rotating ring 302, the connecting bent rod 303 is pushed into the rotating frame 2. During the rotation of the fixed rod 304 with the rotating ring 302, it always contacts the rotating frame 2. The horizontal cross-section of the fixed plate 401 is an isosceles triangle, and the area of the cross-section of the fixed plate 401 gradually increases from bottom to top. The moving trajectory of the rightmost edge line of the fixed plate 401 is located on the vertical plane where the contact surfaces of the two sliding baffles 402 are located. The fixed plate 401 is located on the right side of the connecting column 3, and the sliding baffles 402 are located on the right side of the installation shell 1. The inclined surface of the fixed plate 401 squeezes the two sliding baffles 402 to move them away from each other, so as to ensure that the connecting column 3 can smoothly enter the installation shell 1 for storage. Initially, the plane where the uppermost end of the fixed plate 401 is located is higher than the plane where the uppermost end of the connecting column 3 is located. By driving the connecting column 3 to rotate through the fixed rod 304 and the connecting bent rod 303, combined with the movement of the sliding baffles 402, the connecting column 3 enters the installation shell 1 for storage protection, preventing the landslide on the slope from directly impacting the connecting column 3 and effectively protecting the monitoring data of this device, which is convenient for subsequent recovery and analysis of the monitoring data.

[0039] Workflow: When a landslide or rockfall occurs on the slope, if this device monitors that the connecting column 3 is about to be impacted and there is a possibility of loss of monitoring data in the module on the connecting column 3, the control box starts the motor 301. The output shaft of the motor 301 drives the rotating ring 302 to rotate clockwise (viewed from front to back) through the gear and the toothed ring. The rotating ring 302 drives the fixed rod 304 to move synchronously. The fixed rod 304 squeezes and pushes the connecting bent rod 303 to move backward. The connecting bent rod 303 compresses the connected spring, and the connection between the connecting bent rod 303 and the telescopic end of the hydraulic cylinder 201 is released. When the connecting bent rod 303 moves backward to the limit, the rotating ring 302 drives the rotating frame 2 to rotate synchronously through the fixed rod 304 and the connecting bent rod 303. The rotating frame 2 drives the connecting column 3 to move synchronously. The right edge line of the fixed plate 401 is inserted between the two sliding baffles 402. The inclined surface of the fixed plate 401 pushes the sliding baffle 402 to move. The sliding baffle 402 compresses the connected spring, and the two sliding baffles 402 move away from each other, and the space inside the installation shell 1 is opened.

[0040] With the rotation of the rotating frame 2, the connecting column 3 gradually enters the installation shell 1. Subsequently, the sliding baffle 402 loses the extrusion and moves back to its original position under the elastic force of the connected spring, and the space inside the installation shell 1 is closed again. When the connecting column 3 swings to the vertical state, the control box turns off the motor 301, and the connecting column 3 is isolated and protected inside the installation shell 1 to prevent the soil and stones sliding down the slope from directly hitting the connecting column 3, protecting the security of the monitoring data of this device and facilitating the operator to analyze the disaster based on the data.

[0041] Please refer to Appendix Figure 3 and AppendixFigure 4 As shown in the figure, the auxiliary fixing component includes: a rotating circular plate 501, rotatably connected to the rotating frame 2. A support plate 502 is slidably connected inside the rotating frame 2. The support plate 502 is in extrusion fit with the connecting column 3. A spring is fixedly connected between the rotating circular plate 501 and the support plate 502, which is used to fix the relative positions of the rotating frame 2 and the connecting column 3; two sliding blocks 503, respectively slidably connected in the corresponding blind holes of the rotating frame 2. The sliding blocks 503 are in extrusion fit with the limiting blocks 4. The auxiliary fixing component further includes: a stop block 601, slidably connected to the mounting shell 1. A spring is fixedly connected between the stop block 601 and the mounting shell 1. The stop block 601 is in limit fit with the blind hole on the rotating frame 2, which is used to keep the rotating frame 2 fixed when the connecting column 3 is installed.

[0042] In the above solution, it aims to ensure the stability of the state of the connecting column 3 during the use of the device, prevent the connecting column 3 from shaking in strong winds or other situations, and affect the stability of the shooting picture of the video monitoring module. The side surface of the sliding block 503 is an arc surface and coincides with the spherical surface of the side wall of the rotating frame 2, which is used to ensure that the rotating frame 2 is not hindered during the rotation on the mounting shell 1. The stop block 601 is provided with an inclined surface that slopes from top to bottom and to the left. Cooperating with the blind hole on the rotating frame 2, the rotating frame 2 can only rotate clockwise (viewed from front to back). The elastic coefficient of the spring connected to the stop block 601 is less than the elastic coefficient of the spring connected to the limiting block 4. After the limiting block 4 enters the blind hole of the rotating frame 2, the sliding block 503 pushes the stop block 601 out of the blind hole of the rotating frame 2, and the stop block 601 releases the limit on the rotating frame 2. By limiting the rotating frame 2 with the stop block 601 and combining with the support plate 502 to push the connecting column 3, the stability of the fixed state of the connecting column 3 in the rotating frame 2 is ensured.

[0043] Working process: Before the operator prepares to insert the connecting column 3 into the rotating frame 2, the stop block 601 is located in the blind hole of the rotating frame 2, the rotating frame 2 is limited, and the rotating circular plate 501 is located at the lower part of the rotating frame 2. Subsequently, the operator inserts the connecting column 3 into the rotating frame 2. The stop block 601 ensures that the position of the rotating frame 2 remains stable when the connecting column 3 is installed, enabling the connecting column 3 to be accurately installed. The connecting column 3 squeezes and pushes the support plate 502 to move downward, and the support plate 502 compresses the connected spring. When the limiting block 4 enters the blind hole of the rotating frame 2, the support plate 502 is limited by the elastic force of the connected spring and the limiting block 4, so that the relative positions of the rotating frame 2 and the connecting column 3 are stably fixed. After that, repeat the operation of fixing the relative positions of the mounting shell 1 and the rotating frame 2 to ensure the stability of the state of the connecting column 3 after installation, and reduce the interference of strong wind weather on the monitoring state of the device.

[0044] Embodiment 2: On the basis of Embodiment 1, please refer to the attached Figure 1 - attached Figure 4 and attached Figure 10As shown in the figure, it further includes a quick disassembly mechanism disposed on the rotating circular plate 501 for quickly releasing the connection state between the rotating frame 2 and the connecting column 3. The quick disassembly mechanism includes: a rotating pull rod 701 fixedly connected to the rotating circular plate 501. The rotating pull rod 701 penetrates through the rotating circular plate 501 and the support plate 502. A blind hole is provided in the lower part of the connecting column 3, and the rotating pull rod 701 is slidably connected to the support plate 502; a limiting rod 702 fixedly connected to the rotating pull rod 701, and the limiting rod 702 is in limiting cooperation with the blind hole on the connecting column 3 for connecting the rotating pull rod 701 and the connecting column 3. Four protrusions are provided in the lower part of the blind hole on the connecting column 3, and the limiting rod 702 is in extrusion cooperation with the protrusions in the blind hole of the connecting column 3, so that the rotating pull rod 701 drives the connecting column 3 to move through the limiting rod 702. The limiting block 4 is provided with an inclined surface, and the distance between the inclined surfaces of the two limiting blocks 4 gradually decreases from top to bottom, for releasing the connection between the rotating frame 2 and the connecting column 3.

[0045] In the above solution, it is aimed to enable the connecting column 3 to perform quick installation, replacement and disassembly operations, and reduce the convenience for the operator to recover the monitoring data. The protrusions in the blind hole of the connecting column 3 are evenly distributed circumferentially. Two mirror-image grooves are provided on the rotating circular plate 501, so that after the rotating circular plate 501 rotates to a set angle, it can lose the connection with the rotating frame 2. The area of the projection of the connecting column 3 on the horizontal plane is smaller than the area of the middle space of the rotating frame 2, so that the connecting column 3 can be removed from this device through the rotating frame 2. After the connecting column 3 is installed, the uppermost end of the limiting rod 702 group fits with the upper side surface of the blind hole of the connecting column 3, and the lower side surface of the limiting rod 702 coincides with the plane where the upper side surface of the convex block in the blind hole of the connecting column 3 is located. The lowermost part of the rotating pull rod 701 is a grip, and the lowermost end of the rotating pull rod 701 is within the spherical range of the side wall of the rotating frame 2, so that the rotating pull rod 701 does not contact any parts during the rotation of the rotating frame 2. By rotating the rotating pull rod 701, the connection state between the rotating circular plate 501 and the rotating frame 2 is changed, achieving the purpose of quickly taking away the monitoring data of this device and ensuring the rapidity of data recovery when this device is used.

[0046] Working process: when the connecting column 3 is inserted into the rotating frame 2, the limiting rod 702 is inserted into the blind hole of the connecting column 3, and the limiting rod 702 does not contact the protrusion in the blind hole of the connecting column 3. When a landslide disaster occurs, the rotating circular plate 501 rotates to the uppermost side of the rotating frame 2, and the connecting column 3 is stored and protected in the mounting shell 1. If the operator needs to recover the monitoring data of the device, the operator only needs to dig out the uppermost end of the device. The operator holds the rotating pull rod 701 and rotates it. The rotating pull rod 701 drives the rotating circular plate 501 to rotate synchronously. When the groove on the rotating circular plate 501 forms a set angle with the rotating frame 2, the rotating circular plate 501 is connected to the rotating frame 2. The relationship is released, the limit rod 702 cooperates with the protrusion in the blind hole of the connecting column 3, the operator lifts the rotating pull rod 701, and the rotating pull rod 701 drives the connecting column 3 to move synchronously through the limit rod 702. The limit block 4 is inclined and squeezes the edge of the blind hole of the rotating frame 2. The limit block 4 moves into the connecting column 3 and compresses the connected spring. The connecting column 3 moves out of the device through the middle of the rotating frame 2. The limit block 4 moves and resets under the elastic force of the connected spring. The recovery of the monitoring data in the device is now completed. If the device is continued to be used in the future, all parts will be restored to their initial positions, and the above-mentioned installation and angle adjustment operations of the connecting column 3 can be repeated, and the device can continue to be used to monitor the slope.

Based on the explanation here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the scope of protection of the present invention.
