Description

A civil engineering seismic structure

technical field

The invention relates to the technical field of earthquake resistance in civil engineering, in particular to an earthquake resistance structure for civil engineering.

Background technique

The pipeline connection in the prior art is mostly realized by clamps. However, the structure of rigid connection of pipelines through clamps in the prior art can realize the sealed connection of two separate pipelines, but the connection is subject to external stress such as earthquakes. Under the action, it will be twisted and deformed to different degrees, or even broken, which will affect the sealing between the two separation pipes, resulting in the leakage of conveying liquid or gas, which will not only affect the continued work and use, but also cause greater environmental pollution. The problem is that it cannot meet the use requirements of the seismic function of the pipeline connection;

Therefore, the seismic resistance of the pipeline becomes very important, and special deformation requirements are put forward on the key parts of the pipeline connection, which is an effective solution to realize the seismic connection of the pipeline;

However, we did not establish a set of complete and scientific tests when designing the corresponding seismic structure for the pipeline earthquake, so that the designed seismic structure was put into use without sufficient scientific and experimental demonstration, lacking the perfect and scientific test meaning. Due to the inability to optimize and improve the seismic structure, and then improve its function and improve the seismic protection performance of the pipeline connection parts, when it is put into production and use in the future, there will be great uncertainty in the magnitude of the earthquake that occurs in different regions, and It is impossible to produce optimal seismic protection for the pipeline according to the different conditions in different regions;

In view of the above, we provide a civil engineering seismic structure for solving the above problems.

According to the recorded data, springs with different elastic coefficients are set up, and the optimal spring is found through many tests. Make the shaking frequency of the connection box within a certain reasonable range (that is, to achieve better buffering for the connection box, it will not cause the connection box to shake too much when it encounters an earthquake);

Detailed ways

The foregoing and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of the embodiments with reference to FIGS. 1 to 20 . The structural contents mentioned in the following embodiments are all Reference is made to the drawings in the description.

Embodiment 1, this embodiment provides a civil engineering earthquake-resistant structure, as shown in FIG. 2 , including a base plate 1 , which is characterized in that a bearing plate 2 is longitudinally slidably installed in the base plate 1, and a first The spring 3 is connected with a connection box 4 which is vertically slidably matched with it (the setting of the first spring 3 is used to realize the effect of buffering the connection box 4 when it is subjected to seismic longitudinal waves). Referring to Figure 3, the connection box 4. A moving cylinder 5 is slidably installed at both ends of the transverse direction. Referring to Figure 6, a vertical adjusting ring 6 is rotated and installed on both longitudinal sides of the moving cylinder 5, and a second spring is connected between the moving cylinder 5 and the connecting box 4. 7 (When the moving cylinder 5 moves in the connection box 4, the second spring 7 is driven to stretch, thereby achieving a certain buffering effect on the seismic wave), the vertical adjustment ring 6 is rotated and installed on the upper and lower sides of the vertical adjustment ring 8, The conveying pipe 9 is coaxially fixed in the longitudinal adjusting ring 8. When an earthquake occurs (the earthquake will cause seismic waves and the seismic waves are divided into longitudinal waves and transverse waves, the longitudinal splashing will force the conveying pipe 9 to shake vertically, and the transverse waves will force the conveying pipe 9 to sway vertically. The conveying pipe 9 shakes in the horizontal direction, and it should be reminded here that when an earthquake occurs, since the propagation speed of the longitudinal wave is faster than that of the transverse wave, the longitudinal wave will first travel to the ground and the destructive force of the longitudinal wave generated by the earthquake is less than that of the ground. destructive power of seismic shear waves);

Because the conveying pipes 9 in different seismic zones are affected by longitudinal waves differently (the magnitudes of longitudinal waves generated by earthquakes in different regions are different), therefore, when the substrates 1 in different seismic regions are affected by longitudinal waves, the vertical swaying The amplitudes are also different, that is, one end of the conveying pipe 9 will shake vertically (the base plate 1 is shaken vertically to drive the conveying pipe 9 matched with the base plate 1 to shake vertically) and the other end (with the other The vertical shaking amplitude of the substrate 1) is relatively small. At this time, referring to FIG. 6, the vertical adjustment ring 6 connected to the two ends of the same conveying pipe 9 will rotate to match the amplitude of the shaking at both ends. different, since the distance between the two adjacent substrates 1 remains unchanged, along with the difference in the vertical shaking amplitude of the two adjacent substrates 1, the connection between the two substrates 1 becomes larger. At this time, we pass the conveying pipe 9 The hose 10 is connected to the transition pipe 11 fixedly installed in the connection box 4, which can achieve the effect of increasing the length of the conveying pipes 9 of the two adjacent substrates 1, which is used to match the different vertical shaking amplitudes of the substrates 1. Attention should be paid here. The point is, when the seismic longitudinal wave is transmitted to the ground, we first release the positioning device of the moving cylinder 5 through the triggering device arranged in the base plate 1, and only after the moving cylinder 5 is released from the positioning, can the two ends of the conveying pipe 9 be in the position. When affected by longitudinal waves of different sizes, it can shake vertically and drive the hose 10 connected to it to extend. The positioning device cooperates with the moving cylinder 5, so that when no earthquake occurs, the moving cylinder 5 can be reliably positioned. , to prevent the moving cylinder 5 from shaking, thereby affecting the connection between the pipes;

Similarly, the shear wave generated by the earthquake will reach the ground after the longitudinal wave. At this time, the two adjacent substrates 1 are affected by the shear wave and will drive the conveying pipe 9 to sway back and forth in the longitudinal direction as shown in FIG. 1. The substrates in different areas 1. The magnitude of the impact of the shear wave is different, and the amplitude of its movement is also different. At this time, the two ends of the same conveying pipe 9 are affected by the seismic shear wave and their swaying amplitude is also different, which in turn leads to the rotation of the longitudinal direction installed in the vertical adjustment ring 6. The adjusting ring 8 rotates to match the different amplitudes of the longitudinal shaking of the conveying pipe 9. Whether the conveying pipe 9 is affected by longitudinal waves or transverse waves, it will drive the moving cylinder 5 to slide in the connecting box 4 (both ends of the conveying pipe 9 are vertically or horizontally). The different amplitudes of longitudinal shaking will cause torsion at the connection between the two ends of the conveying pipe 9 and the hose 10. If the distance that the moving cylinder 5 slides outward is too large, it will cause the connection between the conveying pipe 9 and the hose 10 to be torn) and Extend the corresponding hose 10. Referring to Figures 3 and 4, annular baffles 12 are fixed laterally on the moving cylinder 5. The two annular baffles 12 cooperate with each other so that when the moving cylinder 5 slides outwards for a certain amount of time When the distance is too large, under the action of the annular baffle 12, it will no longer slide, so as to avoid the excessive shaking of the conveying pipe 9 and the excessive twisting of the connecting part between the conveying pipe 9 and the hose 10, resulting in tearing;

Before the annular baffle 12 located in the connection box 4 has not yet abutted against the side wall of the connection box 4, the connection box 4 has been kept fixed with the base plate 1 under the action of the locking device, that is, the connection box 4 and its corresponding There will be no relative positional movement between the substrates 1. Preferably, we are provided with an unlocking device in the connection box 4 for unlocking the locking device to the carrier plate 2. When the annular baffle 12 located in the connection box 4 interferes with the connection When the side wall of the box 4 is placed, the moving cylinder 5 moves outward to the maximum distance at this time, and the distance between the connecting lines between the adjacent two connecting boxes 4 is also at the maximum value. , that is, at this time, the connection box 4 moves longitudinally in the base plate 1 along with the carrying plate 2, and we assume that the expansion springs 13 connected between the carrying plate 2 and the base plate 1 are in a compressed state at the initial stage (without encountering an earthquake). , when the bearing plate 2 moves in the base plate 1, it needs to overcome the elastic potential energy of the expansion spring 13 to realize the buffering of the bearing plate 2. With the continuous progress of the earthquake, the bearing plate with a smaller shaking amplitude is affected by the earthquake. The plate 2 moves longitudinally along the corresponding base plate 1 under the driving of another adjacent carrier plate 2. At this time, the conveying pipe 9 and the hose 10 connected to both ends thereof are already in the maximum extension range. , the bearing plate 2 with a larger shaking amplitude affected by the earthquake drives the bearing plate 2 with a smaller shaking amplitude affected by the earthquake to move in the longitudinal direction through the conveying pipe 9, and then realizes the buffering of seismic waves by overcoming the elastic potential energy of the expansion spring 13;

When there is relative movement between the carrier plate 2 and the base plate 1, we rotate the detection gear 14 installed in the carrier plate 2 to cooperate with the detection rack 15 to drive the control device arranged on the carrier plate 2. The control device can Realize the positioning of the locking device when the carrying plate 2 moves longitudinally in the base plate 1 (so that the locking device will not hinder the movement of the carrying plate 2 during the movement of the carrying plate 2 in the base plate 1), when the seismic wave disappears , under the action of the telescopic spring 13 (the telescopic spring 13 has a certain elastic potential energy when it is initially set), the carrying plate 2 moves to the initial position and stops moving, and at this time, the control device controls the locking device to realize the locking of the carrying plate 2 again;

Specifically, when carrying out the test, referring to Figure 1, we placed two adjacent substrates 1 on different seismic simulation shaking tables, and simulated longitudinal waves and transverse waves generated when an earthquake occurred through the earthquake simulation shaking table, and the two Each earthquake simulation shaking table applies different levels of seismic waves to the corresponding substrate 1 to simulate the difference in the magnitude of the seismic waves received by the substrate 1 in different seismic zones when encountering a real earthquake, which makes the shaking amplitude of the substrate 1 Different sizes are used to simulate the real scene in the earthquake. Since the earthquake simulation shaking table is an existing technology, it will not be introduced in detail in this scheme. First reach the ground), so that the trigger device releases the positioning of the positioning device to the moving cylinder 5, so that the moving cylinder 5 can move in the connection box 4 to achieve the effect of moving the conveying pipe 9, and then apply a transverse direction to the substrate 1 at a certain time interval. Vibration (vibration along the extension direction perpendicular to the conveying pipe 9), and then simulate the impact of seismic shear waves on the conveying pipe 9;

The conveying pipe 9 shakes vertically and along the direction perpendicular to the extending direction of the conveying pipe 9 under the action of vibration, so that when the moving cylinder 5 moves to the maximum distance, the unlocking device releases the locking device from the corresponding carrier plate 2 at this time. Locked, and then the relative movement between the bearing plate 2 and the corresponding substrate 1 occurs. Since the destructive force of the longitudinal wave generated by the earthquake is small, the destructive force of the shear wave is relatively large. The influence of the conveying pipe 9. Similarly, when we set up the seismic structure, we also focus on the seismic protection of the conveying pipe 9 when it is subjected to seismic shear waves (the conveying pipe 9 is subjected to vibration perpendicular to its extension direction). Therefore, we will carry the load The plate 2 is slidably installed in the base plate 1 along the direction perpendicular to the extension of the conveying pipe 9. Preferably, when the bearing plate 2 reciprocates in the base plate 1 (affected by the seismic shear wave), the bearing plate 2 is affected by the seismic shear wave. Influence, so that the carrier plate 2 located in the adjacent two substrates 1 reciprocates in the corresponding substrate 1 (the carrier plate 2 that is greatly affected by the seismic shear wave passes through the conveying pipe 9, the moving cylinder 5, the vertical adjustment ring 6, The longitudinal adjustment ring 8 drives another adjacent bearing plate 2 that is less affected by the seismic shear wave), we use the trigger plate 18 fixed on the bearing plate 2 and the arc plate installed on the side wall of the base plate 1 by sliding laterally. 17 (the arc-shaped plate 17 is arranged at the position of the central dividing line of the base plate 1), so that during the reciprocating movement of the carrier plate 2, when the trigger plate 18 moves to the position corresponding to the arc-shaped plate 17, the The arc plate 17 moves in the direction away from the trigger plate 18 and compresses the return spring 16, and then records the frequency and times of the reciprocating movement of the carrier plate 2 through the recording device, and then collects and organizes the test data to study the application of the same level size. When there is a seismic wave, by changing the elastic coefficient of the telescopic spring 13 connected between the base plate 1 and the bearing plate 2, and then changing the reciprocating frequency of the bearing plate 2 when it is vibrated, an optimal solution is found, so that the bearing plate 2 is subjected to vibration. Under the action of the telescopic spring 13, the reciprocating frequency of the bearing plate 2 is within a reasonable range during the earthquake of the corresponding level;

Through this device, we can design the seismic structure for pipeline connection parts according to different regions according to different geographical conditions (the magnitude of earthquakes in different regions is also different).

Embodiment 2, on the basis of Embodiment 1, as shown in FIG. 9 , the carrier plate 2 is longitudinally slidably installed on the bottom wall of the base plate 1 through the cylinder 19 integrally connected with it, and the bottom wall of the base plate 1 is fixedly installed with the cylinder 19 . 19 The sliding rail 20 for longitudinal sliding fit, the locking device includes a locking column 21 which is arranged coaxially with the column 19 and is vertically slidably installed on the column 19, and a locking spring 22 is connected between the locking column 21 and the column 19. The slide rail 20 is provided with a locking hole 23 which is matched with the locking column 21;

Initially, when the annular baffle 12 of the moving cylinder 5 at one end of the connecting box 4 does not abut against the side wall of the connecting box 4, the locking column 21 is inserted into the locking hole provided on the slide rail 20 under the action of the locking spring 22 In 23, the locking effect on the bearing plate 2 is realized. At this time, the conveying pipe 9 is affected by the earthquake, and only drives the corresponding moving cylinder 5 to move in the connection box 4 and realizes the preliminary buffering of the earthquake through the second spring 7. , so that when the moving cylinder 5 cannot continue to move outward under the limit of the annular baffle 12, the unlocking device just acts on the inclined block 24 and drives the locking column 21 to move upward, so that the locking column 21 moves upward and compresses the locking The spring 22, and then the locking column 21 is withdrawn from the locking hole 23, and the locking of the bearing plate 2 is released. At this time, the bearing plate 2 reciprocates in the base plate 1 under the action of the seismic shear wave, and the bearing plate 2 is reciprocated by the expansion spring 13. (connection box 4 ), and at this time, the control device achieves the effect of positioning the locking post 21 withdrawn from the locking hole 23 .

Embodiment 3, on the basis of Embodiment 1, referring to FIG. 7, the unlocking device includes an L-shaped rack 25 fixedly connected with the moving cylinder 5, and the L-shaped rack 25 is engaged with an unlocking gear 26, along with the moving cylinder. The movement of 5 synchronously drives the L-shaped rack 25 fixedly connected with it to move, and the L-shaped rack 25 drives the unlocking gear 26 transmission device through the unlocking gear 26 meshed with it. Referring to FIG. 8, the unlocking gear 26 transmission device drives the The two triangular blocks 28 installed on the carrier plate 2 by sliding laterally move toward each other, and the triangular blocks 28 cooperate with the inclined blocks 24 to force the locking column 21 to move upward, so that the moving cylinder 5 is located in the annular ring at one end of the connecting box 4. When the baffle 12 touches the side wall of the connection box 4, at this time, the locking column 21 is driven upward and completely withdrawn from the locking hole 23 by the matching inclined block 24 and the triangular block 28, as shown in FIG. 10;

The transmission device of the unlocking gear 26 includes a worm 29 that rotates coaxially with the unlocking gear 26, and the worm 29 drives a worm wheel 27 that is rotatably installed in the connection box 4. The third rack and pinion transmission device 31 is driven in accordance with the vertical displacement change between the connection box 4 and the carrying plate 2 , and the two triangular blocks 28 are driven to move toward or away from each other through the third rack and pinion transmission device 31 .

Embodiment 4, on the basis of Embodiment 2, as shown in FIG. 14, the detection rack 15 is fixedly installed on a lateral side wall of the slide rail 20, and as shown in FIG. 10, the detection gear 14 is rotated and installed in the cylinder 19. 12, the control device includes an insulating plate 32 that is rotatably mounted on the carrier plate 2 and rotates coaxially with the detection gear 14. A rectangular conductive frame 33 is fixed on the insulating plate 32, as shown in FIG. 13 , the rectangular conductive frames 33 are respectively connected with the arc conductive plates 34 arranged at vertical intervals and matched with conductive rings 35 fixedly mounted on the carrier plate 2. The upper end surface of the carrier plate 2 is fixed with a cylinder 37 and The two conductive rings 35 are installed on the inner wall of the cylinder 37 at a vertical interval. Referring to Figure 11 , magnets 36 are respectively fixed on the longitudinal sides of the insulating plate 32 on the carrier plate 2, and the two magnets 36 are arranged in the N-level and S-level opposite to each other. ;

When the bearing plate 2 reciprocates in the direction of the slide rail 20 in the base plate 1 under the action of seismic waves, as shown in FIG. It rotates, and then synchronously drives the insulating plate 32 that rotates coaxially with the detection gear 14 to rotate, and the insulating plate 32 rotates to drive the rectangular conductive frame 33 to rotate between the two magnets 36, so that the rectangular conductive frame 33 cuts the magnetic field line to generate current, The rectangular conductive frame 33, the arc-shaped conductive plate 34, and the conductive ring 35 form a closed circuit (if a part of the conductor in the closed circuit cuts the magnetic field line in the magnetic field, the electrons in the conductor will be affected by the Lorentz force, Lorenz force This force is a non-static force, which can cause a potential difference to generate a current, which is called an induced current). As long as the carrier plate 2 moves along the slide rail 20, the detection gear 14 passes through the insulating plate 32 that rotates coaxially with it. The rectangular conductive frame 33 is driven to cut the magnetic field line, and the ammeter detects the current generated in the loop. When the seismic wave gradually weakens and disappears, the bearing plate 2 moves to the initial position under the action of the expansion spring 13 and no longer slides along the The rail 20 moves, and the detection gear 14 also stops rotating synchronously. At this time, the rectangular conductive frame 33 no longer cuts the magnetic field line, and the ammeter detects that the current in the loop disappears. At this time, the ammeter is electrically connected to the micro-controller. The controller controls the locking column 21 to move downward, so that the locking column 21 moves downward under the action of the locking spring 22 and is reinserted into the locking hole 23 to achieve the effect of repositioning the carrier plate 2 .

Embodiment 5, on the basis of Embodiment 4, how the control device realizes the positioning of the locking column 21 withdrawn from the locking hole 23 will be described in detail in this embodiment, referring to FIG. 10 . , we are connected to the lateral sides of the bottom of the locking column 21 via the positioning springs 38 with the positioning columns 39 installed in a lateral sliding fit (initially, the positioning springs 38 are in a compressed state). The cylinder 19 above the rail 20 is provided with a positioning hole 40 which is matched with the positioning column 39. When the locking column 21 is completely withdrawn from the locking hole 23, the positioning column 39 just moves to the position of the positioning hole 40 and the positioning column 39 is at the position of the positioning hole 40. Under the elastic force of the positioning spring 38, it is inserted into the positioning hole 40 to achieve the positioning effect of the locking column 21;

We fix an electromagnet in the cylinder 19 and the electromagnet is connected in series in the first voltage stabilization loop, and we fix a conductive sheet on the side of the positioning column 39 facing the electromagnet, when the ammeter detects that the current in the loop disappears, the microcontroller The first voltage-stabilizing circuit is controlled to be turned on and the electromagnet is energized to generate electromagnetic force, and the positioning column 39 located in the positioning hole 40 is sucked out from the positioning hole 40 by electromagnetic force, and is retracted into the locking column 21 again. The locking column 21 is inserted downward into the locking hole 23 under the action of the locking spring 22 to realize the locking effect on the carrier plate 2, but when the ammeter detects that the current in the loop is generated, the microcontroller controls the first voltage stabilization loop to disconnect, At this time, the electromagnet does not have electromagnetic force, and when the locking column 21 is just completely withdrawn from the locking hole 23 (the carrier plate 2 has not started to move at this time), the positioning column 39 is bounced into the position under the action of the positioning spring 38. In the positioning hole 40 , the positioning of the locking column 21 is realized.

Embodiment 6, on the basis of Embodiment 1, as shown in FIG. 15 , the arc-shaped plate 17 is driven by the first one-way gear 42 rotatably installed in the base plate 1 through the first rack and pinion transmission device 41 , so the The first one-way gear 42 is coaxially rotated with a second one-way gear 43 , the first one-way gear 42 is engaged with an idler gear 44 rotatably installed in the base plate 1 , and the idler gear 44 is engaged with a transmission rotatably installed in the base plate 1 . Gear 45, as shown in FIG. 16, the transmission gear 45 meshes with the second one-way gear 43, as shown in FIG. 15, the transmission gear 45 rotates coaxially with a drive gear 46, as shown in FIG. 14, when When the cylinder 19 is not subjected to seismic waves, the trigger plate 18 is in the middle position in the base plate 1 and is in conflict with the arc-shaped plate 17. At this time, the return spring 16 is in a compressed state. When the seismic wave is generated, the trigger plate 18 is further driven to reciprocate in the base plate 1. Along with the reciprocating motion of the trigger plate 18, when the trigger plate 18 does not contact the arc plate 17, the arc plate 17 moves toward the arc plate 17 under the action of the reset spring 16. It moves in the direction close to the cylinder 19 and drives the first one-way gear 42 to rotate through the first rack and pinion transmission 41. Referring to FIG. 15, the first one-way gear 42 drives the transmission gear through the idler gear 44 meshing with it. 45 rotates and drives the transmission gear 45 to rotate along the set direction (at this time, the second one-way gear 43 is idling, that is, at this time, the second one-way gear 43 cannot drive the transmission gear 45 to rotate), the transmission gear 45 passes through and The coaxially rotating drive gear 46 then drives the recording device to start working. When the trigger plate 18 moves to the position corresponding to the arc plate 17 again, it forces the arc plate 17 to move away from the cylinder 19 and makes the return spring 16 is compressed, and drives the second one-way gear 43 to rotate through the first rack and pinion transmission 41 (at this time, the first one-way gear 42 cannot drive the idler gear 44 to rotate and the first one-way gear 42 is idling at this time), Then the second one-way gear 43 drives the driving gear 46 to rotate through the transmission gear 45 meshed with it (the second one-way gear 43 drives the transmission gear 45 to rotate along the set direction), and the driving gear 46 drives the recording device to work;

The first one-way gear 42 and the second one-way gear 43 are installed in reverse matching, so that whether the arc-shaped plate 17 moves toward the direction close to the cylinder 19 or moves away from the cylinder 19, the first one-way gear 42. The cooperation of the second one-way gear 43, the idler gear 44, and the transmission gear 45 can make the driving gear 46 rotate in a fixed direction, and then the driving gear 46 realizes the alignment of the cylinder 19 (bearing Plate 2) The frequency of the reciprocating movement in the base plate 1 (that is, the number of times the cylinder 19 reciprocates in the base plate 1 from the time the column 19 receives the seismic wave in the direction perpendicular to the conveying pipe 9 until the seismic wave disappears), if The more times the cylinder 19 reciprocates in the base plate 1, it indicates that the expansion spring 13 is soft (that is, the expansion spring 13 cannot provide enough elastic potential energy to the cylinder 19 to prevent the cylinder 19 from being subjected to seismic waves, so that the cylinder 19 is Stop moving in a short period of time. When receiving seismic waves in a direction perpendicular to the conveying pipe 9, the more times the cylinder 19 reciprocates in the base plate 1, the connection between the conveying pipe 9 and the hose 10 will be damaged. The possibility is greatly increased), if the number of reciprocating movements of the cylinder 19 in the base plate 1 is less, it indicates that the telescopic spring 13 is stiff (when the cylinder 19 is subjected to seismic waves in the direction perpendicular to the conveying pipe The magnitudes of the seismic waves received by the substrate 1 are different, so the amplitudes of the two substrates 1 along the direction perpendicular to the conveying pipe 9 are also different. When the smaller base plate 1 moves, too much force acts on the conveying pipe 9, which greatly increases the possibility of damage to the conveying pipe 9). When the conveying pipe 9 is subjected to seismic waves perpendicular to its direction, it has a better protection effect;

By applying different levels of seismic waves to the two substrates 1 each time, and by setting different specifications of the expansion springs 13, when the two adjacent substrates 1 receive the seismic waves from the start of the seismic waves to the disappearance of the seismic waves, the recording device records the inner cylinder 19 of the two substrates 1. The number of reciprocating movements, so as to study the relationship between the selection of the telescopic spring 13 and the magnitude of the seismic wave, and then concluded through the test that when different earthquake levels occur, the optimal telescopic spring 13 is selected to achieve the best transmission pipe 9. Excellent seismic protection effect (applicable to different earthquake levels in different regions, and used to adapt to the seismic resistance of conveying pipes 9 in different regions).

Embodiment 7, on the basis of Embodiment 6, as shown in FIG. 17 , the recording device includes a ring gear 47 that meshes with the drive gear 46 and is rotatably installed in the base plate 1 . When the drive gear 46 moves along the set direction, When rotating, the inner gear 47 is also driven to rotate along the fixed direction, and the scribing pen 48 is fixed on the outer surface of the inner gear 47 along its radial direction. The substrate 1 is provided with a recording ring 67 and records The recording paper matched with the scribing pen 48 is installed on the inner circular surface of the ring 67, that is, every time the trigger plate 18 passes the arc plate 17 (at this time, the arc plate 17 has two actions, that is, the trigger plate 18 forces the The arc-shaped plate 17 moves in the direction away from the cylinder 19. When the arc-shaped plate 17 is separated from the trigger plate 18, under the action of the return spring 16, the arc-shaped plate 17 moves towards the direction close to the cylinder 19). Each action of 17 can drive the inner gear 47 to rotate the same angle in a fixed direction through the driving gear 46, that is, drive the marking pen 48 to slide out the same radian trajectory on the recording paper, when the seismic wave disappears, and wait until the cylinder 19 does not When moving again, by measuring the arc length drawn by the scribing pen 48 on the recording paper (the total arc length obtained by measuring is divided by the arc length drawn by the scribing pen 48 when the arc plate 17 moves each time) , the half of the obtained value is the number of reciprocating movements of the cylinder 19 ), and then the number of reciprocating movements of the cylinder 19 is obtained.

Example 8, on the basis of Example 7, referring to Figures 17 and 18, a bearing ring 49 is fixed on the bottom wall of the substrate 1 and the recording ring 67 is vertically slidably installed in the bearing ring 49, and the marking pen 48 An L-shaped pressing plate 50 is fixed at the bottom, and the L-shaped pressing plate 50 is matched with a U-shaped frame 51 which is longitudinally slidably mounted on the bearing ring 49 , and a lifting spring 52 is connected between the U-shaped frame 51 and the bearing ring 49 . The U-shaped frame 51 drives a third one-way gear 54 rotatably mounted on the bearing ring 49 through the second rack and pinion transmission 53. We set the initial elevating spring 52 to be in a natural extension state and the U-shaped frame 51 and L When the L-shaped pressing plates 50 are in contact with each other, along with the rotation of the ring gear 47, when the L-shaped pressing plate 50 is moved to the contact position with the U-shaped frame 51 again, the ring gear 47 has already rotated one circle at this time. As the ring gear 47 continues to rotate, the L-shaped pressing plate 50 acts on the U-shaped frame 51, thereby forcing the U-shaped frame 51 to move away from the bearing ring 49 and causing the lifting spring 52 to be stretched. The frame 51 drives the third one-way gear 54 to rotate through the second rack and pinion transmission device 53, and the third one-way gear 54 further drives the lifting rack 55 meshed with it to move upward for a certain distance, and then synchronously drives the recording ring 67 to move upward for a certain distance. Distance (when the L-shaped pressing plate 50 and the U-shaped frame 51 are out of contact again, the U-shaped frame 51 moves towards the direction close to the bearing ring 49 under the action of the lifting spring 52, at this time the second rack and pinion transmission device 53 The third one-way gear 54 cannot drive the lifting rack 55 to move, at this time the third one-way gear 54 is idling), we set a limit device on the carrier ring 49 and the limit device can realize the lifting rack 55 every time After moving up a certain distance, the limiting effect of the lifting rack 55 is realized;

When the recording ring 67 moves upward for a certain distance, along with the continuous rotation of the ring gear 47, the scribing pen 48 continues to scribble at another height position on the recording paper.

Embodiment 9, on the basis of Embodiment 8, as shown in FIG. 19 , the limiting device includes: the side of the lifting rack 55 away from the second rack and pinion transmission device 53 is connected to the lifting rack through the limiting spring 56 . 55. The limit post 57 for longitudinal sliding fit. Referring to FIG. 17, a limit plate 58 is fixed on the bearing ring 49, and the limit plate 58 is vertically spaced with a number of limit holes 59 matched with the limit posts 57. , the limit hole 59 cooperates with the limit column 57, so that when the U-shaped frame 51 drives the lifting rack 55 through the second rack and pinion transmission device 53 every time the lifting rack 55 rises a certain distance, the limit column 57 is just at the limit spring. Under the action of 56 , it is inserted into the limiting hole 59 , and the limiting effect on the lifting rack 55 is realized.

Embodiment 10, on the basis of Embodiment 1, referring to FIG. 7, the positioning device includes hydraulic rods 60 fixedly installed on the longitudinal two side walls of the connection box 4, and the hydraulic rods 60 are fixed on the hydraulic rods 60 to cooperate with the moving cylinder 5. The arc-shaped positioning plate 61 is initially in the position of the moving cylinder 5 under the action of the hydraulic rod 60 and the arc-shaped positioning plate 61 when there is no earthquake. Although the civil engineering seismic structure in this scheme is only used for testing , but the structure and function of each part are set to make it possible to protect the conveying pipe 9 to the greatest extent when put into actual production and application. When no earthquake occurs, the hydraulic rod 60 and the arc-shaped positioning plate 61 make the The moving cylinder 5 is in a positioned state, so that when the conveying pipe 9 is subjected to a force other than an earthquake, it will not shake as much as possible, affecting the stability of the conveying pipe 9;

Referring to FIG. 9 , the triggering device includes a rectangular tube 62 disposed in the base plate 1, and resistor sheets are installed on both lateral side walls of the rectangular tube 62. The chip is connected to the negative electrode of the second voltage stabilized loop power supply, and the other resistor chip is connected to the positive electrode of the second voltage stabilized circuit power supply. The sliding plate 64 and the sliding matching parts of the sliding plate 64 on both sides of the sliding plate 64 are installed with a conductive sheet, and an ammeter is connected in series in the second voltage-stabilizing circuit. When the longitudinal wave first reaches the ground, it will cause the sliding plate 64 to shake vertically due to the influence of the seismic longitudinal wave, thereby changing the resistance value of the two resistors in series in the second voltage stabilizer loop. When the change occurs, the ammeter detects that the current in the circuit fluctuates, and at this time, a control system electrically connected to the ammeter (the control system can be a microcontroller, which is used to monitor the current fluctuation and control the hydraulic rod 60 to produce corresponding actions) Control the action of the hydraulic rod 60 and drive the arc-shaped positioning plate 61 to disengage from the moving cylinder 5, so that the moving cylinder 5 changes from the positioning state to the free state, and then the seismic shear wave reaches the ground, and when the two ends of the conveying pipe 9 are subjected to the vertical direction. And when the seismic shear waves of different sizes, drive the moving cylinders 5 located at both ends to move (so that the second spring 7 is stretched to achieve a certain buffer effect);

So that when the earthquake disappears, the sliding plate 64 installed vertically in the rectangular cylinder 62 no longer shakes vertically and the current in the second voltage stabilization circuit also tends to be stable. At this time, the control system controls the hydraulic rod 60 to act. And drive the arc-shaped positioning plate 61 to achieve the positioning effect of the moving cylinder 5 again.

Referring to FIG. 20 , the first one-way gear 42 , the second one-way gear 43 , and the third one-way gear 54 in this solution have the same structure, and all include an outer gear ring 69 and the outer gear ring 69 is rotatably mounted on the On the corresponding gear shaft 68, the inner circular surface of the outer gear ring 69 is provided with a plurality of ratchet teeth 70, and the corresponding gear shaft 68 is rotatably mounted with a pawl 71 matched with the ratchet teeth 70. On the gear shaft 68 An elastic rubber block 63 matched with the pawl 71 is fixed. The elastic rubber block 63 is used to reset the pawl 71. When the outer gear ring 69 is rotated in the counterclockwise direction as shown in FIG. 20, the The outer ring gear 69 cannot drive the shaft of the gear 46 to rotate. At this time, the outer ring gear 69 is idling. When the outer ring gear 69 is rotated in the clockwise direction as shown in FIG. 20, the outer ring gear 69 drives the shaft of the gear 46. Rotate and transmit power.

The civil engineering earthquake-resistant structure is connected by arranging a retractable hose 10 between two adjacent conveying pipes 9, and when encountering an earthquake, a certain displacement can be generated between the two adjacent conveying pipes 9 along the seismic wave direction, that is, the two conveying pipes 9 are The connection part of the pipe 9 can be deformed to a certain degree, and the rigid connection is transformed into a soft connection, which greatly improves the protection ability to deal with earthquakes, so as to better protect the connection parts of the pipeline;

In this scheme, by placing the two substrates 1 on the earthquake simulation platform, and applying longitudinal and transverse seismic waves (simulating the situation when an earthquake occurs), in the case of applying a certain level of seismic waves, through the recording device, it is possible to achieve Record the number of times that the connection box shakes due to the seismic wave in the direction perpendicular to the conveying pipe 9. The number of shaking is too small (indicating that the selected telescopic spring is hard and cannot achieve the buffering effect on the connection box 4) or the number of shaking is too many. (It shows that the selected telescopic spring is soft, which causes the connection box 4 to shake more times, which is also not conducive to the protection of the pipe connection part.) According to the recorded data, springs with different elastic coefficients are set up, and the optimal spring is searched through many tests. , so that the shaking frequency of the connection box 4 is within a certain reasonable range (that is, the better buffering of the connection box 4 is achieved, and the shaking frequency of the connection box will not be too large when it encounters an earthquake);

In this scheme, we can apply different levels of earthquakes to the base plate 1 through the earthquake simulation platform, and then through experiments, it is found that when encountering earthquakes of different levels, the corresponding optimal expansion springs 13 are selected to adapt to different levels of earthquakes. When a grade earthquake occurs, the optimal anti-seismic protection effect is produced for the conveying pipe 9 .
