Detailed implementation mode

[0017] In the prior art, node seismographs are mainly arranged one by one manually and need to be placed at set intervals, resulting in a long arrangement time for node seismographs.

[0018] In view of this, this solution provides a node seismograph retracting and deploying device, which includes a traveling chassis 100, a deploying mechanism 200 installed on the traveling chassis 100, a circulating carrying mechanism 300, and a starting and stopping mechanism 400.

[0019] The following combines Figures 1-14 to detail the structure and shape of the node seismograph retracting and deploying device provided in this embodiment: The traveling chassis 100 is used to drive the deploying mechanism 200, the circulating carrying mechanism 300, and the starting and stopping mechanism 400 to move; the circulating carrying mechanism 300 is used to supply node seismographs to the deploying mechanism 200 one by one; the starting and stopping mechanism 400 is used to turn on and off the node seismographs; the deploying mechanism 200 is used to deploy the turned-on node seismographs one by one, and the deploying mechanism 200 includes a handling structure 210, and the handling structure 210 is used to grab or release the node seismographs.

[0020] In this embodiment, the traveling chassis 100 drives the deploying mechanism 200, the circulating carrying mechanism 300, and the starting and stopping mechanism 400 to move. During this process, the circulating carrying mechanism 300 drives the node seismograph to move below the starting and stopping mechanism 400, and then turns on the node seismograph. Then, the circulating carrying mechanism 300 drives the turned-on node seismograph to move below the deploying mechanism 200, so that the deploying mechanism 200 drives the node seismograph to separate from the circulating carrying mechanism 300. After the node seismograph is deployed on the ground, the handling structure 210 releases it, thus solving the problem of long deployment time of the node seismograph. Regarding the shape and structure of the traveling chassis 100 in more detail: As Figures 7-8 , the traveling chassis 100 includes a chassis frame 110 and driving wheels 120; the driving wheels 120 are installed on the chassis frame 110 and are used to drive the chassis frame 110 to move at a fixed distance along a set route.

[0021] In order to enable the driving wheels 120 to drive the chassis frame 110 to move at a fixed distance along a set route: As Figures 7-8 , the driving wheels 120 include a steering motor 121, a steering bracket 122, a driving motor 123, and traveling rollers 124; the steering motor 121 is installed on the chassis frame 110; the steering bracket 122 is connected to the steering shaft of the steering motor 121; the driving motor 123 is installed on the steering bracket 122, and the driving shaft of the driving motor 123 is connected to the traveling rollers 124.

[0022] In order to increase the number of node seismographs carried by the node seismograph retracting and deploying device: As shown in Figure 7 , a plurality of receiving cylinders 111 are inserted into the chassis frame 110, and the distance between adjacent receiving cylinders 111 is the same as the distance between the node seismographs on the circulating bearing mechanism 300, so as to facilitate the transfer of the node seismographs between the receiving cylinders 111 and the circulating bearing mechanism 300.

[0023] In this embodiment, the steering motor 121 drives the driving motor 123 to rotate through the steering bracket 122, so that the traveling roller 124 moves to the set direction. Then, the driving motor 123 drives the traveling roller 124 to rotate, so that the driving wheel 120 drives the chassis frame 110 to move at a fixed distance along the set route. Regarding the shape and structure of the laying mechanism 200 in more detail: As shown in Figures 3-4 , the laying mechanism 200 further includes a laying bracket 220 and a lifting push rod 230; the laying bracket 220 is installed on the traveling chassis 100, the lifting push rod 230 is installed on the laying bracket 220, and the extending end of the lifting push rod 230 is connected to the handling structure 210; the handling structure 210 includes an annular electromagnet 211; the lifting push rod 230 drives the handling structure 210 to move in the vertical direction, and the annular electromagnet 211 is used to adsorb the node seismograph, and the annular electromagnet 211 grabs or releases the node seismograph by being energized or de-energized.

[0024] In order to ensure the inclination of the placement position of the node seismograph, the handling structure 210 further includes a pressing disc 212, a spherical plain bearing 213 and an inclination sensing element 214.

[0025] As shown in Figure 4 , one end of the spherical plain bearing 213 is connected to the extending end of the lifting push rod 230, and the other end is connected to the pressing disc 212; one end of the pressing disc 212 away from the spherical plain bearing 213 is connected to the annular electromagnet 211; the inclination sensing element 214 is installed on the pressing disc 212 and is used to detect the inclination angle of the pressing disc 212.

[0026] In order to prevent the node seismograph placed on the ground from being in a state of force balance, the handling structure 210 further includes a lifting shaft 215, a travel pin 216 connected to the lifting shaft 215 and a lifting sleeve 217.

[0027] As shown in Figure 4 , one end of the lifting shaft 215 is inserted into the lifting sleeve 217, and the other end is connected to the spherical plain bearing 213; the lifting sleeve 217 is connected to the extending end of the lifting push rod 230, and a travel slot hole is formed on the surface along its own axis direction; the travel pin 216 is inserted into the travel slot hole and can move along the travel slot hole; the lifting sleeve 217 moves along the lifting shaft 215 to prevent the lifting push rod 230 from transmitting pressure to the spherical plain bearing 213.

[0028] To place the nodal seismograph on the ground at a set pressure, the handling structure 210 further includes a pressure sensor 218.

[0029] As Figure 4 , the pressure sensor 218 is installed on the lifting sleeve 217 and is located above the lifting shaft 215. The pressure sensor 218 is used to detect the pressure received. After the nodal seismograph contacts the ground, the reaction force is transmitted to the pressure sensor 218 through the lifting shaft 215. When the reaction force borne by the pressure sensor 218 reaches the threshold value, the annular electromagnet 211 separates from the nodal seismograph.

[0030] In this embodiment, the lifting push rod 230 drives the handling structure 210 to move in the vertical direction. After the annular electromagnet 211 contacts the nodal seismograph, the two are magnetically fixed, and then the nodal seismograph is driven to separate from the circulating bearing mechanism 300. After the nodal seismograph contacts the ground, the lifting shaft 215 moves along the lifting sleeve 217. During this process, the annular electromagnet 211 does not transmit pressure to the nodal seismograph. At the same time, under the action of gravity, the sensing end of the nodal seismograph fits with the placement position, so as to drive the pressing disc 212 to move under the constraint of the spherical plain bearing 213.

[0031] When the inclination of the placement position of the nodal seismograph exceeds the threshold value, the inclination sensing element 214 is triggered. Then, the lifting push rod 230 drives the nodal seismograph to move vertically upward through the handling structure 210, so that the nodal seismograph separates from the ground. Then, the traveling chassis 100 drives the nodal seismograph to move. After the nodal seismograph moves the leveling distance, the above operations are repeated. When the inclination of the placement position of the nodal seismograph is within the normal range, the lifting push rod 230 continues to drive the nodal seismograph to move downward through the handling structure 210. When the lifting shaft 215 contacts the pressure sensor 218, a reaction force is generated between the nodal seismograph and the ground. When the reaction force borne by the pressure sensor 218 reaches the threshold value, the annular electromagnet 211 separates from the nodal seismograph by closing, and then the laying mechanism 200 resets. Regarding the shape and structure of the circulating bearing mechanism 300 in more detail: As Figure 9 , the circulating bearing mechanism 300 includes a circulating pipe 310 and a series plate 320. The circulating pipe 310 and the series plate 320 are hinged. A plurality of circulating pipes 310 and a plurality of series plates 320 are alternately arranged in series to form a ring. The inner cavity of the circulating pipe 310 is used to accommodate the nodal seismograph.

[0032] To prevent the nodal seismograph from being damaged by impact after laying, the circulating bearing mechanism 300 further includes a plurality of protection units 330.

[0033] As Figures 9-10, the protection unit 330 includes a protection cylinder 331; the nodal seismograph is installed in the protection cylinder 331, and the sensing end of the nodal seismograph protrudes from the protection cylinder 331; the protection cylinder 331 is detachably inserted into the inner cavity of the circulation pipe 310.

[0034] To further enhance the protection ability of the protection unit 330 for the nodal seismograph, the protection unit 330 further includes an elastic sleeve 332.

[0035] As Figure 10 , the elastic sleeve 332 is inserted into the protection cylinder 331; the nodal seismograph is inserted into the elastic sleeve 332.

[0036] To enable the protection cylinder 331 to be detachably inserted into the inner cavity of the circulation pipe 310, the circulation pipe 310 includes a pipe body 311 and an elastic insertion ring 312.

[0037] As Figure 10 , the elastic insertion ring 312 is inserted into the pipe body 311; the elastic insertion ring 312 is sleeved on the protection cylinder 331.

[0038] To improve the convenience of disassembling and assembling the nodal seismograph and the circulation bearing mechanism 300, a disassembly and assembly bracket 600 is further included.

[0039] As Figures 1-2 , an annular groove 301 is formed on the outer surface of the protection cylinder 331; the disassembly and assembly bracket 600 is inserted into the annular groove 301 and is slidably connected to the annular groove 301; the circulation bearing mechanism 300 arranges multiple nodal seismographs longitudinally, so that the disassembly and assembly bracket 600 is simultaneously inserted into the annular grooves 301 of multiple protection cylinders 331, and then drives multiple nodal seismographs to be disassembled and assembled with the circulation bearing mechanism 300 through the disassembly and assembly bracket 600.

[0040] In this embodiment, a circular structure formed by connecting multiple circulation pipes 310 and multiple series plates 320 circulates and moves, so that the circulation pipe 310 drives the nodal seismograph to move through the protection unit 330. When the nodal seismograph is deployed, the protection unit 330 separates from the circulation pipe 310 following the nodal seismograph. When the deployed nodal seismograph is impacted, the protection cylinder 331 bears the direct external impact, and then the elastic sleeve 332 cushions and reduces the impact through elastic deformation. When the nodal seismograph is recovered, due to the cylindrical structure characteristics of the protection unit 330, it is convenient for the protection unit 330 to be inserted into the circulation pipe 310, and the elastic insertion ring 312 fixes the protection unit 330 and the circulation pipe 310 through its own elastic deformation.

[0041] When it is necessary to disassemble and assemble the nodal seismographs on the disassembly and assembly circulating bearing mechanism 300, the circulating bearing mechanism 300 arranges multiple nodal seismographs longitudinally, so that the disassembly and assembly bracket 600 is inserted into the annular grooves 301 of multiple protective cylinders 331 at the same time, and then drives multiple nodal seismographs to be disassembled and assembled with the circulating bearing mechanism 300 through the disassembly and assembly bracket 600, thereby improving the convenience of disassembling and assembling the nodal seismographs and the circulating bearing mechanism 300. Regarding how to drive the circulating bearing mechanism 300 to move circularly, a driving mechanism 700 is also included.

[0042] Such as Figure 9 and Figure 11 shown in the figure, the driving mechanism 700 includes a driving bracket 710, a driving motor 720, a follower shaft 730, a driving gear disk 740, a follower gear disk 750 and an anti-falling bracket 760; the driving motor 720 is installed on the driving bracket 710, and its driving shaft is connected to the driving gear disk 740; the follower shaft 730 is rotatably installed on the driving bracket 710, the follower gear disk 750 is sleeved on the follower shaft 730, and the follower shaft 730 can rotate around its own axis and drive the follower gear disk 750 to rotate; the circulating bearing mechanism 300 meshes with the driving gear disk 740 and the follower gear disk 750; the anti-falling bracket 760 is sleeved on the driving bracket 710 and is located below the circulating bearing mechanism 300, and an access hole is opened on the anti-falling bracket 760 so that the protection unit 330 passes through the anti-falling bracket 760 through the access hole.

[0043] In this embodiment, the driving motor 720 drives the driving gear disk 740 to rotate, so that the circulating bearing mechanism 300 moves circularly. The circulating bearing mechanism 300 drives the follower shaft 730 to rotate through the follower gear disk 750 to maintain the stable movement of the circulating bearing mechanism 300. When the nodal seismographs are deployed and recovered, the nodal seismographs installed in the protection unit 330 pass through the anti-falling bracket 760 through the access hole. At the same time, the anti-falling bracket 760 provides support for the protection unit 330 that accidentally moves along the circulating pipe 310. Regarding the shape and structure of the start-stop mechanism 400 in more detail: Such as Figure 9 shown in the figure, the start-stop mechanism 400 includes a start-stop bracket 410 and a magnetic supply component 420; the magnetic supply component 420 is installed on the start-stop bracket 410 and is located above the circulating bearing mechanism 300 for switching on and off the nodal seismographs.

[0044] Regarding the first embodiment of the start-stop mechanism 400 for switching on and off the nodal seismographs: Such as Figure 12 shown in the figure, the magnetic supply component 420 includes a strong magnet 421.

[0045] In this embodiment, the cyclic loading mechanism 300 drives the nodal seismograph under the strong magnet 421 according to the switching rule of the nodal seismograph, so that the strong magnet 421 turns on or off the nodal seismograph through the magnetic field.

[0046] The second embodiment of the start-stop mechanism 400 for turning on and off the nodal seismograph: As Figure 13 , the magnetic supply component 420 includes an electromagnet 422.

[0047] In this embodiment, the cyclic loading mechanism 300 drives the nodal seismograph to move under the electromagnet 422, and the electromagnet 422 releases a magnetic field according to the switching rule of the nodal seismograph to turn on or off the nodal seismograph. In order to detect the operating state of the nodal seismograph after it is turned on, a reference mechanism 800 located below the magnetic supply component 420 is further included.

[0048] As Figure 9 and Figure 14 , the reference mechanism 800 includes a fixed-height convex plate 810, a reference motor 820 and an eccentric turntable 830; the housing of the reference motor 820 is connected to the fixed-height convex plate 810, and its rotating shaft is connected to the eccentric turntable 830; the cyclic loading mechanism 300 drives the nodal seismograph to move to the top of the fixed-height convex plate 810, and the reference motor 820 drives the eccentric turntable 830 to rotate to generate vibration, so that the nodal seismograph receives the vibration.

[0049] In this embodiment, the cyclic loading mechanism 300 drives the nodal seismograph to move to the top of the fixed-height convex plate 810, and the reference motor 820 drives the eccentric turntable 830 to rotate to generate vibration, so that the nodal seismograph receives the vibration. The nodal seismograph transmits the vibration information to the monitoring device through the network. When the vibration information transmitted by the nodal seismograph is abnormal, the cyclic loading mechanism 300 drives the nodal seismograph with abnormal information to move, and this abnormal nodal seismograph does not perform subsequent layout operations, thereby avoiding the lack of monitoring information caused by the layout of ineffective nodal seismographs. In order to realize the adhesion and fixation of the nodal seismograph to the ground, a hot-melt bottom plate 900 installed at the sensing end of the nodal seismograph is further included.

[0050] As Figure 10 and Figure 14 , the reference motor 820 drives the eccentric turntable 830 to rotate, so that the eccentric turntable 830 generates heat by friction with the hot-melt bottom plate 900.

[0051] In this embodiment, the reference motor 820 drives the eccentric turntable 830 to rotate, and the eccentric turntable 830 generates heat by friction with the hot-melt bottom plate 900. After being heated, the viscosity of the hot-melt bottom plate 900 increases, and thus the hot-melt bottom plate 900 fixes it to the ground during the layout process of the nodal seismograph. To enable the reference mechanism 800 to meet the different layout requirements of nodal seismographs, the eccentric turntable 830 includes a turntable body 831, an eccentric block 832, and an adapter backing plate 833.

[0052] As Figure 14 , one end of the turntable body 831 is connected to the rotating shaft of the reference motor 820, and the other end is connected to the adapter backing plate 833; the eccentric block 832 is installed on the turntable body 831 and is used to generate vibrations during rotation; the adapter backing plate 833 is used to adjust the friction coefficient of the eccentric turntable 830.

[0053] In this embodiment, when the nodal seismograph is directly laid out on the ground, the adapter backing plate 833 with a smaller friction coefficient is installed on the turntable body 831 to reduce the frictional force between the sensing end of the nodal seismograph and the eccentric turntable 830; when the nodal seismograph is coupled and fixed to the ground, the adapter backing plate 833 with a larger friction coefficient is installed on the turntable body 831 to increase the frictional force between the adapter backing plate 833 and the hot melt bottom plate 900. Regarding how to recover the laid-out nodal seismograph, a recovery mechanism 500 is also included.

[0054] As Figure 2 , Figure 5 and Figure 6 , the recovery mechanism 500 includes a recovery bent plate 510 and a recovery sensing element 520; the recovery bent plate 510 includes a flared end and a closed end; the recovery bent plate 510 is installed on the traveling chassis 100; the recovery sensing element 520 is installed at the closed end of the recovery bent plate 510; the traveling chassis 100 drives the recovery mechanism 500 to move along the layout route of the nodal seismograph, and the nodal seismograph enters the recovery bent plate 510 through the flared end and triggers the recovery sensing element 520, thereby triggering the layout mechanism 200 to drive the nodal seismograph to reset.

[0055] To guide the nodal seismograph to be inserted into the circular bearing mechanism 300, the recovery mechanism 500 further includes a guide cover 530.

[0056] As Figures 5-6 , the guide cover 530 is provided with a tapered hole, and the inner diameter of the tapered hole gradually decreases from bottom to top; the guide cover 530 is connected to the recovery bent plate 510; the handling structure 210 passes through the tapered hole to grasp or release the nodal seismograph.

[0057] To determine the layout spacing of the nodal seismograph, the recovery mechanism 500 further includes a ranging component 540.

[0058] As Figures 5-6 , the ranging component 540 is installed at the closed end of the recovery bent plate 510; the ranging component 540 is used to measure the distance between the laid-out nodal seismograph and the next layout point, so as to correct the traveling distance of the traveling chassis 100.

[0059] In order to clean the sundries on the road surface during the layout process of the node seismographs, the recycling mechanism 500 further includes a protective arc plate 550 and a cleaning skirt plate 560.

[0060] As Figures 5-6 , the protective arc plate 550 is connected to the recycling bent plate 510, and the ranging component 540 is located in the space formed by the protective arc plate 550 and the recycling bent plate 510; the cleaning skirt plate 560 is connected to the recycling bent plate 510 and the protective arc plate 550.

[0061] In this embodiment, during the layout process of the node seismographs, the traveling chassis 100 drives the recycling mechanism 500 to move along a set route. The recycling bent plate 510 and the protective arc plate 550 form a conical guiding structure. At the same time, the cleaning skirt plate 560 forms an elastic cleaning structure under the conical guiding structure. The conical guiding structure and the elastic cleaning structure cooperate to guide and clean the sundries on the layout route of the node seismographs, thereby avoiding the influence of sundries on the layout of the node seismographs.

[0062] When the layout positions of adjacent node seismographs are on the same straight line, the traveling chassis 100 drives the recycling mechanism 500 to move to the layout position of the node seismograph. Then, the ranging component 540 measures the distance between the layout position and the adjacent node seismograph, and corrects the traveling distance of the traveling chassis 100 according to the measurement result.

[0063] When it is necessary to recycle the node seismograph, the traveling chassis 100 drives the recycling mechanism 500 to move reversely along the set route. The node seismograph enters through the flared end of the recycling bent plate 510. After the node seismograph moves to the closed end of the recycling bent plate 510, it triggers the recycling induction element 520. Then, the lifting push rod 230 drives the handling structure 210 to move vertically downward. After the annular electromagnet 211 contacts the node seismograph, the two are magnetically fixed. Then, the lifting push rod 230 drives the node seismograph to move upward through the handling structure 210. During this process, the guiding cover 530 drives the node seismograph to move on the surface of the annular electromagnet 211 to guide the node seismograph to be inserted into the circulating bearing mechanism 300.

[0064] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
