DETAILED DESCRIPTION

[0031] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0032] Embodiment 1

[0033] As attached Figure 1 To Attachment Figure 3 As shown, the present invention provides an earthquake geological disaster monitoring and early warning device, including a monitoring component 100, including an outer cylinder 101, wherein the outer cylinder 101 is directly inserted into the soil, and a top cover 102 is threadedly connected to the outer cylinder 101, wherein the top cover 102 can provide a location for installing other parts, and a monitoring component 103 connected to the top cover 102, wherein the monitoring component 103 is used to monitor whether settlement occurs;

[0034] The trigger component 200 includes an inner cylinder 201 slidably connected to the outer cylinder 101, wherein the interior of the inner cylinder 201 is used to install parts and provide protection for the parts. The inner cylinder 201 is arranged in the outer cylinder 101, and a protection area is formed by the inner cylinder 201 to protect the internal parts, thereby preventing the soil from affecting the operation of the parts in the inner cylinder 201; a connecting cover 202 threadedly connected to the inner cylinder 201, the connecting cover 202 makes the interior of the inner cylinder 201 closed; and a driving component 203 arranged in the inner cylinder 201, wherein the driving component 203 is used to drive the trigger component 20 4, so that the trigger assembly 204 is horizontally inserted into the soil, the trigger assembly 204 connected to the driving assembly 203, wherein after the trigger assembly 204 is unfolded, the fixing effect can be improved during daily use, and the monitoring assembly 103 can be triggered when settlement occurs, the auxiliary assembly 205 arranged between the outer cylinder 101 and the inner cylinder 201, wherein the auxiliary assembly 205 is used to provide a certain support for the trigger assembly 204, and the shielding assembly 206 arranged on the outer cylinder 101, wherein the shielding assembly 206 is used to prevent the soil from causing adverse effects on the trigger assembly 204;

[0035] The shielding assembly 206 includes a lifting groove 206a opened on the side of the outer cylinder 101. When sedimentation occurs, the trigger assembly 204 will slide downward along the lifting groove 206a and the receiving groove 206b connected to the lifting groove 206a, wherein the receiving groove 206b is used to accommodate the shielding spring 206c and the shielding piece 206d, and can assist the shielding piece 206d to move downward stably, the shielding spring 206c fixedly installed in the receiving groove 206b, and the shielding piece 206d fixedly connected to the shielding spring 206c, wherein the shielding spring 206c provides elastic force to make the shielding piece 206d always resist the insertion rod 204h, thereby preventing soil from entering the lifting groove 206a and affecting the extension of the insertion rod 204h.

[0036] As can be seen from the above, the outer cylinder 101 is inserted into the soil, the driving assembly 203 is operated, the driving assembly 203 drives the trigger assembly 204 to expand, the insertion rod 204h in the trigger assembly 204 extends from the insertion hole 204k, and passes through the lifting groove 206a and is inserted into the soil from the horizontal direction. The outer cylinder 101 and the inner cylinder 201 cooperate to form a protection area to protect the internal parts, so as to prevent the soil from entering and affecting the operation of the parts in the inner cylinder 201. The shielding spring 206c provides elastic force to make the shielding sheet 206d always resist the insertion rod 204h, so as to prevent the soil from entering the lifting groove 206a. The groove 206a affects the extension of the rod 204h. The monitoring component 103 monitors whether settlement occurs. When settlement occurs, the soil gathers toward the outer wall of the outer tube 101 and moves downward. At this time, the downward force of the soil drives the rod 204h to move downward. The rod 204h squeezes the shielding piece 206d to the depth of the accommodating groove 206b and compresses the shielding spring 206c. At the same time, the rod 204h drives the inner tube 201 downward, causing the trigger spring 204i to deform. At this time, the monitoring component 103 monitors the pulling force and transmits data to complete the monitoring work.

[0037] Embodiment 2:

[0038] As attached Figure 1 To Attachment Figure 3 As shown, this embodiment is basically the same as the previous embodiment, except that a conical plug block 101a is fixedly connected to the bottom of the outer cylinder 101, wherein the conical plug block 101a enables the outer cylinder 101 to assist the outer cylinder 101 to break through the ground and quickly insert into the soil, a plurality of friction bevels 101b are fixedly connected to the peripheral side of the outer cylinder 101, wherein the friction bevels 101b can increase the contact area with the soil, thereby increasing the friction force and enhancing the stability of the outer cylinder 101 inserted into the soil, and a pull rope 102a is fixedly connected to the upper surface of the top cover 102, and the outer cylinder 101 can be conveniently pulled out of the soil through the pull rope 102a.

[0039] Specifically, the monitoring component 103 includes an audible and visual alarm 103a fixedly mounted on the upper surface of the top cover 102, which sends out an alarm through sound and light when subsidence occurs, and a pressure sensor 103b fixedly mounted on the lower surface of the top cover 102. A PLC controller is also installed in the inner tube 201, wherein the pressure sensor 103b is used to monitor the pulling force generated by the downward movement of the trigger component 204. When the monitored data is abnormal, the data will be sent to the PLC controller, and the PLC controller will judge the data. When the pulling force exceeds the preset value, the PLC controller will control the audible and visual alarm 103a to send out an alarm.

[0040] As can be seen from the above, the outer cylinder 101 is quickly inserted into the soil through the conical plug block 101a, and the driving component 203 is operated. The driving component 203 makes the trigger component 204 unfold in the horizontal direction and insert into the soil, and the tension of the trigger component 204 is monitored by the pressure sensor 103b. When settlement occurs, the soil will cause the trigger component 204 to move downward along the lifting groove 206a, causing the trigger spring 204i to deform, and generate a downward pulling force on the pressure sensor 103b. When the pressure sensor 103b detects that the tension data is abnormal, it will send the data to the PLC controller, and the PLC controller will judge the data. When the tension exceeds the preset value, the PLC controller will control the sound and light alarm 103a to sound an alarm, thereby realizing the monitoring and early warning of the earthquake.

[0041] Embodiment three:

[0042] As attached Figure 4 To Attachment Figure 6 As shown, this embodiment is basically the same as the previous embodiment, with the difference that the driving assembly 203 includes a driving motor 203a fixedly mounted on the inner lower surface of the inner cylinder 201, wherein the driving motor 203a is a power source, a transmission rod 203b fixedly connected to the driving motor 203a, and a driving gear 203c fixedly connected to the transmission rod 203b, wherein the driving motor 203a drives the transmission rod 203b when working, thereby driving the driving gear 203c to rotate, and the driven gear 203d meshing with the driving gear 203c, the driving gear 203c drives the driven gear 203d to rotate, and a synchronization rod 203e fixedly connected to the driven gear 203d, wherein the synchronization rod 203e rotates together with the driven gear 203d, and a thread is provided on the circumferential side of the synchronization rod 203e.

[0043] Specifically, the size of the driving gear 203c is smaller than that of the driven gear 203d, which can increase the torque and provide a greater force for the insertion rod 204h to move in the horizontal direction. The synchronization rod 203e is rotationally connected to the inner lower surface of the inner cylinder 201.

[0044] Furthermore, the trigger assembly 204 includes a first moving block 204a threadedly connected to the synchronization rod 203e. Since the insertion rod 204h is located in the slot, when the synchronization rod 203e rotates, the first moving block 204a will move upward or downward according to the direction of rotation, a first rotating seat 204b fixedly connected to the first moving block 204a, a first connecting plate 204c fixedly connected to the first rotating seat 204b, when the height of the first moving block 204a changes, the angle between the first moving block 204a and the first connecting plate 204c changes, a second rotating seat 204d rotatably connected to the first connecting plate 204c, when the first moving block 204a moves in the vertical direction, the second rotating seat 204d moves in the horizontal direction with the insertion rod 204h, a second connecting plate 204e rotatably connected to the second rotating seat 204d, and a third rotating seat 204d rotatably connected to the second connecting plate 204e. 04f, a second moving block 204g fixedly connected to the third rotating seat 204f, wherein the second connecting plate 204e, the third rotating seat 204f and the second moving block 204g work together with the first moving block 204a, the first connecting seat and the first connecting plate 204c, and when the distance between the first moving block 204a and the second moving block 204g is reduced, the distance between the two second rotating seats 204d is increased, and vice versa, thereby improving the stability of the horizontal movement of the rod 204h, the rod 204h fixedly connected to the second rotating seat 204d, the rod 204h is initially located in the socket 204k, when the rod 204h moves horizontally, the rod 204h passes through the lifting groove 206a from the socket 204k and is inserted into the soil, and the trigger spring 204i fixedly connected to the upper surface of the connecting cover 202, when the trigger spring 204i is stretched, it will apply tension to the pressure sensor 103b.

[0045] Furthermore, the trigger assembly 204 also includes a guide rod 204j fixedly connected to the lower surface of the connecting cover 202, wherein the guide rod 204j is used to assist the stable movement of the second moving block 204g, and a socket 204k opened on the side wall of the inner tube 201, wherein the insertion rod 204h is initially located in the socket 204k, the guide rod 204j is slidably connected to the second moving block 204g, and the insertion rod 204h is slidably connected to the socket 204k.

[0046] Furthermore, the upper end of the trigger spring 204i is connected to the pressure sensor 103b. When the trigger spring 204i is deformed, the change will be monitored by the pressure sensor 103b. The first rotating seat 204b, the first connecting plate 204c, the second rotating seat 204d, the second connecting plate 204e, the third rotating seat 204f, the insertion rod 204h, and the socket 204k are symmetrically arranged in two groups to improve stability. The two insertion rods 204h inserted into the soil can improve the fixing effect of the outer cylinder 101.

[0047] Furthermore, the auxiliary component 205 includes an auxiliary cylinder 205a fixedly connected to the lower surface inside the outer cylinder 101, a lifting rod 205b slidably connected to the inner wall of the auxiliary cylinder 205a, wherein the auxiliary cylinder 205a is used to make the lifting rod 205b move vertically, and an auxiliary spring 205c sleeved on the periphery of the lifting rod 205b, wherein the auxiliary spring 205c provides an upward force for the lifting rod 205b, thereby providing support for the inner cylinder 201.

[0048] Furthermore, the upper surface of the lifting rod 205b is fixedly connected to the lower surface of the inner tube 201, the upper end of the auxiliary spring 205c is fixedly connected to the inner upper surface of the auxiliary tube 205a, and the lower end of the auxiliary spring 205c is fixedly connected to the lower end of the lifting rod 205b.

[0049] As can be seen from the above, the outer cylinder 101 is inserted into the soil, and the driving motor 203a is started. The driving motor 203a drives the driving gear 203c to rotate through the transmission rod 203b, and then drives the driven gear 203d and the synchronization rod 203e to rotate. When the synchronization rod 203e rotates, it will drive the first moving block 204a to move upward. At this time, the angle between the first moving block 204a and the first connecting plate 204c changes, and the second rotating seat 204d moves in the horizontal direction with the insertion rod 204h. At the same time, the second moving block 204g moves downward along the guide rod 204j. At this time, the distance between the first moving block 204a and the second moving block 204g is reduced, and the distance between the two second rotating seats 204d is increased. Then the rod 204h passes through the lifting groove 206a from the socket 204k and is inserted into the soil. When settlement occurs, the soil gathers toward the outer wall of the outer tube 101 and moves downward. At this time, the downward force of the soil drives the rod 204h to move downward. At the same time, the rod 204h drives the inner tube 201 downward through the socket 204k, causing the trigger spring 204i to deform, thereby generating a downward pulling force on the pressure sensor 103b. When the pressure sensor 103b detects abnormal tension data, it will send data to the PLC controller, which will judge the data. When the tension exceeds the preset value, the PLC controller will control the sound and light alarm 103a to sound an alarm, thereby realizing earthquake monitoring and early warning.
