Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The utility model provides a pair of collecting space area nondestructive test device, including seismograph, seismograph and seismic receiver, seismograph, seismic receiver all belong to prior art, moreover the utility model discloses an invention point is also not here, so no longer give unnecessary details to seismograph, seismic receiver here, the following structure of the novel seismograph of this application of detailed introduction:
as shown in fig. 1, the seismic generator includes a trolley 2, a shaft bracket 23 is installed on the trolley 2, a winding roller 25 and a first motor 24 for driving the winding roller 25 to rotate are installed on the shaft bracket 23, the first motor 24 can also be installed on the trolley 2, the winding roller 25 is driven to rotate through a transmission belt, a lifting rope 5 and a lead 6 are wound on the winding roller 25, the lower ends of the lifting rope 5 and the lead 6 are connected with a seismic cylinder 1, the seismic cylinder 1 can extend into a seismic source installation hole 7 to generate seismic waves, and a threading hole 21 for the lifting rope 5 and the lead 6 to pass through is formed in the trolley 2.
The existing seismic wave generator generates seismic waves by placing a collision block at the bottom of a seismic source mounting hole 7 in advance, then dropping a heavy block from a high position to collide with the collision block, the seismic wave generation mode has low speed and long time interval between the generation of the seismic waves on two adjacent sides, and most importantly, in order to ensure the impact effect, a pipeline is usually arranged in a seismic source mounting hole 7, a heavy block is allowed to fall in the pipeline to impact the impact block, therefore, workers need to spend a large amount of time to disassemble and assemble the pipeline during detection, after all, the depth of the seismic source mounting hole 7 is as long as thirty or more meters, and in addition, the pipeline is generally formed by detachably connecting a plurality of short pipes for facilitating pipeline transportation, the time spent on disassembling and assembling the pipeline accounts for half of the total time spent on nondestructive detection of the whole goaf, it is obvious that the disassembly and assembly of the short pipes are troublesome, and the short pipes in such a large number need to be equipped with special vehicles for consignment.
In order to solve the defects of the existing seismic generator, the seismic generator of the application designs the seismic barrel 1 with a brand new structure, the seismic barrel can extend into the seismic source mounting hole 7 and automatically generates seismic waves at intervals, pipelines do not need to be installed in the seismic source mounting hole 7, the trouble of disassembling and assembling a plurality of short pipes is avoided, the nondestructive testing time of the whole goaf is greatly shortened, the size is small, the weight is light, special vehicle consignment is not needed, the operation is simple and convenient during detection, time and labor are saved, and the practicability is good.
Two different structures of the seismic cylinders 1 are described below by way of two embodiments;
the first embodiment is as follows:
as shown in fig. 2, the seismic wave cylinder 1 comprises a cylinder body 11, an electromagnet 12 and an impact block 15 are fixedly mounted at the upper end and the lower end of the cylinder body 11 respectively, an armature 13 is slidably mounted in the cylinder body 11, and a permanent magnet 14 attracted with the electromagnet 12 is mounted on the armature 13;
when the electromagnet 12 is electrified, the electromagnet 12 generates magnetic force to repel the permanent magnet 14, the permanent magnet 14 drives the armature 13 to accelerate and slide downwards in the cylinder 11, and the impact block 15 is impacted to generate shock waves;
when the electromagnet 12 is energized with the current II, the electromagnet 12 generates magnetic force to attract the permanent magnet 14, and the permanent magnet 14 drives the armature 13 to slide upwards in the cylinder 11 and attract the electromagnet 12.
The current directions of the first current and the second current in the electromagnet 12 are opposite;
in order to prevent the permanent magnet 14 from being damaged due to violent impact attraction with the electromagnet 12, the current of the first current should be larger than that of the second current in order to make the armature 13 impact the impact block 15 to generate shock waves with sufficient intensity.
The electromagnet 12 is controlled to alternately supply the first current and the second current, so that the seismic wave cylinder 1 can be controlled to automatically generate a seismic wave in the seismic source mounting hole 7 at intervals.
The first current and the second current are alternately introduced into the electromagnet 12, which can be controlled by manual operation (for example, two control switches are arranged, one control switch controls the on-off of the first current, and the other control switch controls the on-off of the second current), or can be automatically controlled by the controller 3:
the structure of the controller 3 is shown in fig. 1 and 4, and includes an insulating box 31 and a second motor 4 fixedly mounted on the insulating box 31, an insulating hub 34 drivingly connected with the second motor 4 is disposed in the insulating box 31, the second motor 4 drives the insulating hub 34 to rotate when rotating, a section of arc-shaped conductive sheet 35 is mounted on the circumferential surface of the insulating hub 34, two pairs of brushes, such as a first brush 32 and a second brush 33 in fig. 4, are fixedly mounted on the inner wall of the insulating box 31, the first brush 32 and the second brush 33 are not in contact with the arc-shaped conductive sheet 35 at the same time, the first brush 32 is connected in series with a first lead 61, the second brush 33 is connected in series with a second lead 62, one end of the first lead 61 and the second lead 62 is connected with a battery 22 (such as shown in fig. 1, the battery 22 is disposed on the trolley 2), the other end is connected with an electromagnet 12, when the first, the first lead 61 is connected, at the moment, the second lead 62 is in a disconnected state, and on the contrary, when the second brush 33 is contacted with the arc-shaped conducting strip 35, the second lead 62 is connected, at the moment, the first lead 61 is in a disconnected state;
as shown in fig. 4, the distance between the two first brushes 32 is smaller, the distance between the two second brushes 33 is larger, and the rotating speed of the insulating hub 34 is constant, so the first conducting wire 61 has a long energizing time, and the second conducting wire 62 has a short energizing time, so a small current, i.e., a second current, is introduced into the first conducting wire 61, and a large current, i.e., a first current, is introduced into the second conducting wire 62, because the current is smaller, the magnetic force generated by the electromagnet 12 is smaller, which is suitable for the electromagnet 12 to attract the armature 13, and the permanent magnet 14 is not easy to be damaged by attracting impact; when the battery 22 is large, the magnetic force generated by the electromagnet 12 is large, the repulsive force to the permanent magnet 14 is also large, and the armature 13 obtains a large acceleration, so that the acceleration enables the armature 13 to rapidly increase in speed in a short time, and finally to impact the impact block 15 at a relatively large speed to generate a shock wave.
As shown in fig. 1, the first wire 61 and the second wire 62 are wound together to form the wire 6, and the wire 6 is wound around the winding roller 25.
As shown in fig. 2, in order to obtain a good impact effect of the seismic cylinder 1, the impact block 15 is preferably provided with a plurality of vent holes 16, so that when the armature 13 moves down rapidly, air between the armature 13 and the impact block 15 of the impact block 15 can be discharged through the vent holes 16 without significantly blocking the armature 13.
Example two:
the difference between the present embodiment and the first embodiment is that the vent hole is arranged at a different position, and the present embodiment arranges the vent hole on the cylinder 11, and as shown in fig. 3, a second vent hole 17 is arranged on the cylinder 11 between the armature 13 and the impact block 15.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
