Description

Technical Field

[0001] The present application relates to the field of seismographs, and more particularly to a seismograph with anti-pulling wiring. Background Art

[0002] A seismograph utilizes the inertia of a suspended heavy object. During an earthquake, the ground vibrates while it remains stationary. The vibrations recorded by the seismograph are a curve with different amplitudes of undulation, called a seismic spectrum. It should be noted that a seismograph can only be used to measure the intensity and direction of an earthquake and cannot be used to predict earthquakes.

[0003] After retrieval, as disclosed in a Chinese patent document, an auxiliary component for a portable seismograph [Application No.: CN202320675556.5; Publication No.: CN220569975U]. This includes an instrument and three data connectors, and the data connectors are arranged on the right side of the instrument. By using the cooperation of the data connector, plug connector, support frame, moving block, groove, receiving groove, docking device and docking groove, the moving block is pushed to drive the L-shaped plate to move in the L-shaped groove. When the movable block drives the plug connector to insert into the data connector, the pull plate is released, and the tension spring undergoes elastic deformation to drive the movable block back to its original position. The movement of the movable block drives the docking block to insert into the docking groove, which can prevent the plug connector from detaching. However, the above device can only strengthen the connection between the plug connector and the data connector. When the wire is dragged, it cannot provide a buffering effect, easily drives the seismograph to move, and is not conducive to the safe use of the seismograph. Summary of the Invention

[0004] In order to provide anti-pulling and buffering effects on the connecting cable of a seismograph, the present application provides a seismograph with anti-pulling wiring.

[0005] The seismograph with anti-pulling wiring provided by the present application adopts the following technical solutions:

[0006] A seismograph with anti-pulling wiring includes an instrument body. A plurality of data connection holes are provided on the side end of the instrument body, and a plurality of plug connectors are arranged outside the data connection holes. Two symmetrically distributed sliding holes are opened on the side end of the instrument body close to the data connection holes, and sliding sleeves are slidably arranged in the sliding holes. An installation plate is fixed between the two sliding sleeves, and a card interface matching the plug connector is arranged on the installation plate for placing the plug connector. A sliding rod is slidably arranged in the sliding sleeve. A vertical plate is fixed between the two sliding rods, and a plurality of notches are arranged on the vertical plate for placing the wire of the plug connector. After the plug connector is placed in the card interface, the plug connector is aligned with the corresponding data connection hole. A clamping mechanism is arranged on the side of the vertical plate close to the data connection hole for clamping the wire of the plug connector. A elastic traction mechanism is arranged at the bottom of the sliding hole for pulling the sliding rod into the sliding hole.

[0007] By adopting the above technical solution, the plug connector is clamped on the mounting plate, and its wire is clamped on the vertical plate through the clamping mechanism. When the vertical plate is pushed inward, the sliding rod and the sliding sleeve are both inserted into the sliding hole. Multiple plug connectors can be docked with the data connection holes at one time, and there will be redundant wires bent and stored between the vertical plate and the mounting plate. When the wire is pulled, the vertical plate moves outward, and the elastic traction mechanism provides a backward pulling force on it. During the stretching process of the redundant wire, it can buffer the pulling force and prevent it from pulling the instrument body.

[0008] Preferably, a lateral groove is formed on the inner wall of the side end of the sliding hole, and a bottom groove is formed on the inner wall of the bottom of the sliding hole. Arc-shaped grooves are provided at both ends of the bottom groove. A long slot is formed at the side end of the sliding sleeve. A limiting gasket is fixed to the side end of the sliding rod, and the limiting gasket is slidably arranged in the long slot. An elastic metal sheet is fixed to the bottom of one end of the sliding sleeve close to the inner side of the sliding hole, and both ends of the elastic metal sheet are fixed to the sliding sleeve, and an arc-shaped protrusion is arranged at the middle position thereof. The arc-shaped protrusion matches the arc-shaped groove and, under the action of the elastic metal sheet, abuts in the arc-shaped groove.

[0009] By adopting the above technical solution, the sliding distance of the limiting gasket in the long slot can limit the sliding of the sliding rod in the sliding sleeve to prevent the sliding rod from separating from the sliding sleeve. The elastic metal sheet can also limit the movement of the sliding sleeve. Moreover, when the sliding sleeve is in the two positions of sliding out and sliding in, the arc-shaped groove and the arc-shaped protrusion exactly coincide, improving the stability of the mounting plate when the operator disassembles and installs the cable and facilitating the operation of the operator.

[0010] Preferably, the clamping mechanism includes a bent elastic rod fixed to the inner side of the sliding rod. One end of the bent elastic rod is located inside the sliding sleeve, and the other end bends inward. A convex block is arranged on the inner side of the bent elastic rod, and the convex block abuts against the inner eaves of one end of the sliding sleeve. When the bent elastic rod enters the sliding sleeve along with the sliding rod, the convex block abuts against the inner wall of the sliding sleeve, and the bent elastic rod can be squeezed to fit with the sliding rod. A cross bar extends inward from one end of the bent elastic rod away from the sliding sleeve. A plurality of clamping rods are fixed to the upper end of the cross bar. The corresponding clamping rods on the two cross bars are respectively located on both sides of the corresponding notch, and a clamping block is arranged at the upper end of the clamping rod.

[0011] By adopting the above technical solution, when the two sliding rods contract into the sliding sleeve, the two bent elastic rods are squeezed by the inner wall of the sliding sleeve and fit with the sliding rods. At this time, the two cross bars move to both sides, driving the two corresponding clamping rods at the corresponding positions to approach each other and clamp the wire, preventing the wire from sliding. Moreover, under the action of the clamping block, the contact area between the clamping rod and the wire can be increased, improving the clamping stability.

[0012] Preferably, the elastic traction mechanism includes a spring hole formed at the bottom of the sliding hole. A connecting sleeve is slidably arranged inside the spring hole, and one end of the connecting sleeve close to the sliding hole is sealed. A connecting piece is fixed inside the connecting sleeve. A tension spring is fixed at the bottom of the spring hole. The tension spring is located inside the connecting sleeve, and the other end thereof is fixedly connected to the connecting piece. A rotating rod is rotatably arranged inside the sliding rod. An eccentric wheel is fixed at one end of the rotating rod close to the connecting sleeve. An eccentric hole matching the eccentric wheel is formed at one end of the connecting sleeve close to the sliding hole. The eccentric wheel can be rotated to a non-aligned state with the eccentric hole.

[0013] By adopting the above technical solution, after the sliding rod and the sliding sleeve are retracted into the sliding hole, the eccentric wheel will pass through the aligned eccentric hole and insert into the inner side of the connecting sleeve. Then, the operator can rotate the rotating rod to make the eccentric wheel in a non-aligned state with the eccentric hole. After that, when the wire is pulled, the sliding rod moves outwards, and the eccentric wheel cannot pass through the eccentric hole. The sliding rod will drive the connecting sleeve to move synchronously, thereby stretching the tension spring. The buffer effect is provided by the tension spring, making the connection between the connecting sleeve and the sliding rod controllable. When the operator places the plug, there is no need to fix the vertical plate by hand, which is more convenient to operate.

[0014] Preferably, a lever is fixed at the end of the rotating rod away from the eccentric wheel. Two symmetrically distributed limiting blocks are fixed on the vertical plate, and the two limiting blocks are respectively located below the two levers. When the lever rotates to abut against the limiting block, the eccentric wheel is aligned with the eccentric hole.

[0015] By adopting the above technical solution, the operator can rotate the rotating rod through the lever, and when the lever rotates to abut against the limiting block, the eccentric wheel is aligned with the eccentric hole, which is more beneficial for the operator to judge whether the eccentric wheel and the eccentric hole are in an aligned state, further facilitating the operation.

[0016] Preferably, elastic clamping plates are fixed on the inner wall of the sliding hole. Two support rods are arranged on the elastic clamping plates, and clamping claws are arranged at the ends of the support rods. A limiting hole is formed on the inner side wall of the sliding sleeve. When the sliding sleeve is retracted into the sliding hole, the clamping claws extend into the sliding sleeve, and the clamping claws are aligned with the limiting hole.

[0017] By adopting the above technical solution, when the connecting sleeve is pulled out, its end will squeeze the elastic clamping plate towards the edge, making the clamping claws stuck in the limiting hole, thereby preventing the sliding sleeve from moving outwards and preventing the plug from separating from the data connection hole.

[0018] Preferably, rubber feet are arranged at the bottom of the instrument body.

[0019] By adopting the above technical solution, the rubber feet can provide an anti-slip effect and improve the placement stability of the instrument body.

[0020] Preferably, a round hole is formed in the middle position of the rubber foot pad, and a lifting piston is slidably arranged in the round hole. A widened sleeve is arranged at the edge of the lifting piston to prevent the lifting piston from tilting. A long groove is formed in the bottom of the instrument body, and a long rod is slidably arranged in the long groove. The long rod is located above the rubber foot pad, and a first inclined piece is arranged at the bottom of the long rod. A second inclined piece is arranged at the upper end of the lifting piston. The first inclined piece abuts against the second inclined piece. A compression spring is arranged between the upper end of the lifting piston and the bottom of the instrument body. Both the first inclined piece and the second inclined piece are located inside the compression spring. A square groove is formed in the upper inner wall of the long groove, and an inclined groove is formed above the square groove. An extrusion piece is fixed above the long rod, and the extrusion piece is located inside the square groove. An inclined rod is slidably arranged in the inclined groove. One end of the inclined rod abuts against the extrusion piece, and the other end extends into the spring hole. A notch is formed in the bottom of the connecting sleeve, and the upper end of the inclined rod abuts in the notch.

[0021] By adopting the above technical solution, when the connecting sleeve moves outwards, the inclined rod can be pushed downwards. The bottom of the inclined rod can push the long rod through the extrusion piece. The first inclined piece and the long rod will move synchronously, and the second inclined piece can be pulled upwards. Moreover, under the action of the widened sleeve, the lifting piston can be prevented from tilting when rising. Once the lifting piston moves upwards, a negative pressure area will be formed inside the round hole below its inner side, adsorbing the rubber foot pad on the placement tabletop, improving the stability of the instrument body, and preventing the instrument body from being damaged due to being pulled and falling.

[0022] A detection method for a seismograph includes the following steps:

[0023] S1: Prepare equipment, and prepare the seismograph, sensor, cable and installation tools completely.

[0024] S2: Determine the installation position, and select a stable and solid ground or foundation as the installation site, away from possible interference sources such as large mechanical equipment and roads.

[0025] S3: Install the sensor, and install the sensor of the seismograph according to the requirements of the instruction manual. If it is installed on the ground, usually ensure that the sensor is in close contact with the ground, and it can be fixed with bolts or glue, etc. For a vertical pendulum seismograph, use a level to ensure that its vertical axis is consistent with the direction of gravity.

[0026] S4: Connect the cable, and correctly connect the cable between the sensor and the seismograph.

[0027] S5: Initialize the settings, turn on the power of the seismograph, enter the setting interface of the instrument, and perform initialization parameter settings.

[0028] S6: Start monitoring with the seismograph. The seismograph will collect and record seismic signals in real time and store the data in the internal memory or external storage device.

[0029] S7: Data transmission, the collected data is transmitted in real time to a remote data center or monitoring platform for further analysis;

[0030] S8: After the detection is completed, confirm that the data transmission is completed, disassemble the seismograph and the sensor, clean the sensor, and finally pack it up.

[0031] In summary, the present application includes at least one of the following beneficial technical effects:

[0032] 1. The mounting plate and the vertical plate are used to fix the plug connector and the wire respectively. During the process of connecting the plug connector, the wire between the vertical plate and the mounting plate will be bent and stored. When the wire is pulled, the vertical plate moves outwards, and the elastic traction mechanism provides a backward pulling force on it. During the stretching of the excess wire, it can provide a buffer for the pulling force to prevent it from pulling the instrument body;

[0033] 2. With the help of the mounting plate, multiple plug connectors are placed in the card interfaces, and then by pushing the mounting plate, multiple plug connectors can be installed at one time, without the need for operators to connect the wires frequently, making the operation more convenient.

[0054] The following Figures 1-12 further elaborates on this application in conjunction with the attached drawings.

[0055] This application example discloses a wiring anti-pulling seismograph.

[0056] Refer to Figure 1 and Figure 2, The wiring anti-pulling seismograph includes an instrument body 1 and a number of plug connectors. A number of data connection holes for connecting the plug connectors are provided at the side end of the instrument body 1. A sliding sleeve 3 is slidably provided at the side end of the instrument body 1 close to the data connection holes. A mounting plate 4 is fixed between the two sliding sleeves 3. A card interface for placing the plug connector is provided on the mounting plate 4. After the plug connector is placed in the card interface, the plug connector is aligned with the corresponding data connection hole. A sliding rod 5 is slidably provided in the sliding sleeve 3. A vertical plate 6 is fixed between the two sliding rods 5. A number of notches for placing the wire of the plug connector are provided on the vertical plate 6. Four rubber feet 7 for anti-slip are provided below the instrument body 1, which can improve the stability of the instrument body 1 during use.

[0057] When wiring, the plug connector is clamped on the mounting plate 4, and its wire is clamped on the vertical plate 6. When the vertical plate 6 is pushed inward, multiple plug connectors can be docked with the data connection holes at one time, and the sliding rod 5 and the sliding sleeve 3 retract into the inner side of the instrument body 1, and the distance between the mounting plate 4 and the vertical plate 6 decreases. There will be excess wire bent and stored between the vertical plate 6 and the mounting plate 4. When the wire is pulled, the vertical plate 6 can move outward. Cooperating with the rubber feet 7, it can prevent the instrument body 1 from being pulled during the stretching of the excess wire, improving the stability of the instrument body 1.

[0058] Reference Figure 3 and Figure 4 , A sliding hole 2 for the sliding sleeve 3 to slide is opened at the side end of the instrument body 1. A lateral groove 23 is opened on the inner wall of the side end of the sliding hole 2, and a bottom groove 21 is opened on the inner wall of the bottom of the sliding hole 2. Arc-shaped grooves 22 are provided at both ends of the bottom groove 21. A long slot 31 is opened at the side end of the sliding sleeve 3. A limiting gasket 51 is fixed to the side end of the sliding rod 5, and the limiting gasket 51 is slidably provided in the long slot 31 and the lateral groove 23 to slide-limit the sliding rod 5. An elastic metal sheet 32 is fixed to the bottom of the sliding sleeve 3, and both ends of the elastic metal sheet 32 are fixed to the sliding sleeve 3, and an arc-shaped protrusion 33 pointing downward is provided at the middle position. The arc-shaped protrusion 33 matches the arc-shaped groove 22, and the arc-shaped protrusion 33 can contract upward when subjected to pressure and slide in the bottom groove 21 to slide-limit the sliding sleeve 3. When the sliding sleeve 3 is in the two positions of sliding out and sliding in, the arc-shaped groove 22 and the arc-shaped protrusion 33 exactly coincide, improving the stability of the mounting plate 4 when the operator disassembles and assembles the cable and facilitating the operator's operation.

[0059] Reference Figure 5, a clamping mechanism 8 is provided inside the vertical plate 6. It can clamp the wire when the slide rod 5 contracts and loosen the wire when the slide rod 5 extends to the longest state, facilitating the operator to install and remove the wire. The clamping mechanism 8 includes a bent elastic rod 81. The bent elastic rod 81 is fixed inside the slide rod 5 and bends towards the inside of the slide rod 5. A convex block 82 is provided inside the bent elastic rod 81. When the bent elastic rod 81 enters the sliding sleeve 3 along with the slide rod 5, the convex block 82 abuts against the inner wall of the sliding sleeve 3, and can squeeze the bent elastic rod 81 to fit with the slide rod 5. The twisted end of the bent elastic rod 81 extends horizontally towards the inside with a cross bar 83, and the two cross bars 83 connected to the two bent elastic rods 81 are in contact with each other. A plurality of clamping rods 84 are fixed to the upper end of the cross bar 83. The corresponding clamping rods 84 on the two cross bars 83 are respectively located on both sides of the corresponding notch. When the two cross bars 83 move towards both sides respectively, the clamping rods 84 thereon can clamp the wire. Coupled with the clamping blocks 85 provided at the upper ends of the clamping rods 84, the area of clamping the wire is increased, the damage to the wire is reduced, and the clamping stability is improved at the same time.

[0060] When the two slide rods 5 contract into the sliding sleeve 3, the two bent elastic rods 81 are squeezed by the inner wall of the sliding sleeve 3 and fit with the slide rods 5. At this time, the two cross bars 83 move towards both sides, driving the two clamping rods 84 at the corresponding positions to approach each other and clamp the wire. When the slide rod 5 fully extends, the convex block 82 is located outside the sliding sleeve 3, and the two bent elastic rods 81 are not subjected to extrusion force. They reset under the action of their own elastic potential energy and release the clamped wire, facilitating the operator to disassemble and assemble the wire.

[0061] Reference Figure 6 and Figure 7, a elastic traction mechanism 9 for providing a pulling force to the sliding rod 5 is provided at the bottom of the sliding hole 2, which can provide a better buffering effect when the wire is pulled. The elastic traction mechanism 9 includes a spring hole 91 parallel to the sliding hole 2 and located at the bottom of the sliding hole 2. A connecting sleeve 92 is slidably arranged inside the spring hole 91. A limiting groove is arranged on the inner wall of the spring hole 91. A limiting strip matching with it is arranged on the outer side of the connecting sleeve 92, which can prevent the connecting sleeve 92 from rotating in the spring hole 91. One end of the connecting sleeve 92 close to the sliding hole 2 is sealed and provided with an eccentric hole 95. A connecting piece 93 is fixed inside the connecting sleeve 92. A tension spring 94 is arranged inside the connecting sleeve 92. One end of the tension spring 94 is connected to the bottom of the spring hole 91, and the other end is fixedly connected to the connecting piece 93. A rotating rod 96 is rotatably arranged inside the sliding rod 5. An eccentric wheel 97 is fixed at one end of the rotating rod 96 close to the connecting sleeve 92. The eccentric wheel 97 can change the alignment state with the eccentric hole 95 by rotating. Moreover, a lever 98 is fixed at the end of the rotating rod 96 far from the eccentric wheel 97. Two symmetrically distributed limiting blocks are fixed on the vertical plate 6, and the two limiting blocks are respectively located below the two levers 98. When the lever 98 rotates to abut against the limiting block, the eccentric wheel 97 is aligned with the eccentric hole 95, which is more conducive to the operator to judge whether the eccentric wheel 97 and the eccentric hole 95 are in an aligned state.

[0062] When the operator connects the wire, the sliding rod 5 is not connected to the connecting sleeve 92 and can be stably placed without being held by hand. After the sliding rod 5 and the sliding sleeve 3 are retracted into the sliding hole 2, the eccentric wheel 97 will pass through the aligned eccentric hole 95 and insert into the inner side of the connecting sleeve 92. Then the operator can rotate the rotating rod 96 to make the eccentric wheel 97 and the eccentric hole 95 in a non-aligned state. After that, when the wire is pulled, the sliding rod 5 moves outwards, and the eccentric wheel 97 cannot pass through the eccentric hole 95. The sliding rod 5 will drive the connecting sleeve 92 to move synchronously, so as to stretch the tension spring 94. The buffer effect is provided through the tension spring 94, making the connection between the connecting sleeve 92 and the sliding rod 5 controllable and the operation more convenient.

[0063] Reference Figure 5 and Figure 9 , an elastic clamping plate 10 is fixed on the inner wall of the sliding hole 2. Two support rods are arranged on the elastic clamping plate 10, and clamping claws are arranged at the ends of the support rods. A limiting hole 34 is arranged on the inner side wall of the sliding sleeve 3. When the sliding sleeve 3 is retracted into the sliding hole 2, the clamping claws extend into the inside of the sliding sleeve 3. When the connecting sleeve 92 is pulled out, its end will squeeze the elastic clamping plate 10 towards the edge, so that the clamping claws are stuck in the limiting hole 34, which can prevent the sliding sleeve 3 from moving outwards, thereby preventing the plug connector from separating from the data connection hole and improving the connection stability between the card connector and the data connection hole when the wire is pulled.

[0064] Reference Figure 6 、 Figure 10 and Figure 11, a circular hole 71 is provided in the middle position of the rubber foot pad 7, a lifting piston 72 is slidably arranged in the circular hole 71, the lifting piston 72 and the rubber foot pad 7 form a sucker-like structure, a widened sleeve 75 for preventing the lifting piston 72 from tilting is arranged at the edge of the lifting piston 72, a long groove 11 is provided at the bottom of the instrument body 1, a long rod 12 is slidably arranged in the long groove 11, the long rod 12 is located above the rubber foot pad 7, and under the action of the rubber foot pad 7, the long rod 12 will not fall off. A first inclined piece 17 is arranged at the bottom of the long rod 12, a second inclined piece 74 is arranged at the upper end of the lifting piston 72, the upper inclined surface of the first inclined piece 17 abuts against the lower inclined surface of the second inclined piece 74, and a compression spring 73 is arranged between the upper end of the lifting piston 72 and the bottom of the instrument body 1 to ensure that the lifting piston 72 is located at the bottom of the circular hole 71. A square groove 13 is provided in the upper inner wall of the long groove 11, and an inclined groove 15 is provided above the square groove 13. An extrusion piece 16 is fixed above the long rod 12, and the extrusion piece 16 is located inside the square groove 13. An inclined rod 14 is slidably arranged in the inclined groove 15. One end of the inclined rod 14 abuts against the extrusion piece 16, and the other end extends into the spring hole 91. A notch 99 is provided at the bottom of the connecting sleeve 92, and the upper end of the inclined rod 14 abuts in the notch 99.

[0065] When the connecting sleeve 92 moves outwards, the outer side wall of the connecting sleeve 92 can squeeze the inclined rod 14 downwards. The bottom of the inclined rod 14 will push the long rod 12 through the extrusion piece 16. The first inclined piece 17 and the long rod 12 will move synchronously, and then pull the second inclined piece 74 upwards. Moreover, under the action of the widened sleeve 75, it can prevent the lifting piston 72 from tilting when rising, ensuring the sealing performance between the lifting piston 72 and the side wall of the circular hole 71. When the lifting piston 72 moves upwards, a negative pressure area will be formed in the space below it, adsorbing the rubber foot pad 7 on the placement tabletop, improving the stability of the instrument body 1, and preventing the instrument body 1 from being damaged due to being pulled and falling. On the contrary, when the wire is not pulled, the bottom of the lifting piston 72 contacts the placement tabletop and no adsorption effect will be generated, which is convenient for the operator to pick up the instrument body 1.

[0075] During the process of using the seismograph, the operator needs to have certain seismology knowledge and instrument operation skills, operate strictly in accordance with the instrument's instruction manual, and regularly maintain and calibrate the instrument to ensure its normal operation and the accuracy of the data.

[0076] The implementation principle of a seismograph with anti-pulling wiring in this application is as follows: The plug connector and the wire are fixed by the mounting plate 4 and the vertical plate 6 respectively. After connecting the plug connector, the wire between the vertical plate 6 and the mounting plate 4 will be bent and stored. When the wire is pulled, the stored wire is stretched, providing a buffer for the pulling force to prevent it from pulling the instrument body 1.

[0077] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
