Description

Technical Field

[0001] This utility model relates to the field of detection technology, and more specifically, to a blasting vibration detector. Background Technology

[0002] A blasting vibration detector is a specialized device used to measure, record, and analyze ground vibration signals caused by blasting operations. In modern engineering, blasting vibration detectors are widely used in various engineering projects such as mining, tunnel construction, and building demolition.

[0003] Existing explosion vibration detectors typically consist of a data acquisition and recording unit, sensors, and a PC. First, plaster powder is applied to the ground and mixed with water to make it viscous. Then, the sensor is placed flat on the plaster powder and pressed down until it solidifies. This step secures the sensor and stabilizes the measurement. The sensor detects the physical signals of ground vibration in real time and converts them into electrical signals. The acquired vibration signals are transmitted to the on-site data acquisition and recording unit. Finally, the data acquisition and recording unit transmits the data to the PC, where analysis and processing software reads the data stored in the recorder and performs operations such as display, feature parameter extraction, and result output. This completes the working process of the explosion vibration detector.

[0004] However, existing sensors require additional plaster powder when fixed to the ground. If plaster powder is forgotten, it may cause errors due to shaking during sensor operation, affecting the measurement results. Furthermore, plaster powder is often stored in a bucket, and the lid needs to be opened and the bucket tilted when pouring it, which is quite cumbersome. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model proposes a blasting vibration detector.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a blasting vibration detector, including a data acquisition and recording device, a sensor electrically connected to the outside of the data acquisition and recording device, a storage bucket fixedly connected to the outside of the sensor, a pair of baffles slidably connected to the bottom of the storage bucket, a sealing cap installed at the top of the storage bucket, a connecting plate fixedly connected to the opposite ends of the pair of baffles, a pair of limiting rods slidably connected inside the connecting plate, both of the limiting rods being fixedly connected to the outside of the storage bucket, a fixing plate fixedly connected to the end of the limiting rod away from the storage bucket, and a traction mechanism for pulling the connecting plate provided on the outside of the storage bucket.

[0007] Furthermore, the traction mechanism includes a ring plate, a traction rope, a guide wheel, a side plate, and a spring. The ring plate is slidably connected to the outside of the storage bucket. One end of the traction rope is fixed to the top of the ring plate, and the end of the traction rope away from the ring plate is fixed to a connecting plate and passes through the fixed plate. The guide wheel is fixed to the outside of the storage bucket and is in contact with the traction rope. The side plate is fixed to the outside of the storage bucket, and both ends of the spring are fixed to the ring plate and the side plate, respectively.

[0008] Furthermore, a second spring is provided on the outer side of the connecting plate, the second spring is fixedly connected to the connecting plate, and the end of the second spring away from the connecting plate is fixedly connected to the fixing plate.

[0009] Furthermore, a slot is provided on the outer side of the storage bucket, a locking rod is slidably connected inside the ring plate, a pair of limiting rods are fixedly connected to the outer side of the ring plate, a fixing plate is fixedly connected to the end of each pair of limiting rods away from the ring plate, a sliding plate is slidably connected to the outer side of the pair of limiting rods, the sliding plate is fixedly connected to the locking rod, and a spring is fixedly connected between the sliding plate and the fixing plate.

[0010] Furthermore, the outer side of the storage bucket is fitted with transparent glass, and rubber pads are glued to the adjacent ends of the pair of baffles.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 - Figure 3 As shown, a blasting vibration detector includes a data acquisition and recording device 1. A sensor 2 is electrically connected to the outside of the data acquisition and recording device 1. A storage bucket 3 is fixedly connected to the outside of the sensor 2. A pair of baffles 4 are slidably connected to the bottom of the storage bucket 3. A sealing cover 5 is installed on the top of the storage bucket 3. A connecting plate 6 is fixedly connected to the opposite ends of the pair of baffles 4. A pair of limiting rods 7 are slidably connected inside the connecting plate 6. The pair of limiting rods 7 are fixedly connected to the outside of the storage bucket 3. A fixing plate 8 is fixedly connected to the end of the limiting rods 7 away from the storage bucket 3. A traction mechanism for pulling the connecting plate 6 is provided on the outside of the storage bucket 3.

[0022] The existing sensor 2 requires additional plaster powder when fixed to the ground. Forgetting to bring plaster powder can cause errors due to shaking during sensor 2 operation, affecting measurement results. Furthermore, the plaster powder is often stored in a bucket, requiring the lid to be opened and the bucket tilted when emptying, which is cumbersome. This invention, however, involves opening the sealing cap 5 beforehand, adding plaster powder through the top of the storage bucket 3, and then closing the sealing cap 5. At this point, the storage bucket 3 contains plaster powder, effectively ensuring the sensor 2 operates smoothly during subsequent operation. To avoid forgetting to bring plaster powder, when plaster powder needs to be added to the ground, a pair of connecting plates 6 can be pulled away from the storage bucket 3 by the traction mechanism. When the connecting plates 6 move, the baffles 4 will move simultaneously. At this time, the pair of baffles 4 will open the bottom of the storage bucket 3, and the plaster powder inside the storage bucket 3 can fall out under the action of gravity. The process is convenient and there is no chance of forgetting to prepare plaster powder. After the plaster powder is added, the traction mechanism will automatically reset and move the pair of baffles 4 back to the initial position.

[0023] like Figure 2 and Figure 3 As shown, the traction mechanism includes a ring plate 9, a traction rope 10, a guide wheel 11, a side plate 12, and a spring 13. The ring plate 9 is slidably connected to the outside of the storage bucket 3. One end of the traction rope 10 is fixed to the top of the ring plate 9, and the end of the traction rope 10 away from the ring plate 9 is fixed to the connecting plate 6. The traction rope 10 passes through the fixing plate 8. The guide wheel 11 is fixed to the outside of the storage bucket 3 and is in contact with the traction rope 10. The side plate 12 is fixed to the outside of the storage bucket 3. The two ends of the spring 13 are fixed to the ring plate 9 and the side plate 12, respectively.

[0024] When the ring plate 9 is pressed down, it pulls the traction rope 10. The traction rope 10, under force, pulls the connecting plate 6. The connecting plate 6, under force, moves along the outside of the limiting rod 7, opening the seal at the bottom of the storage bucket 3. When the ring plate 9 moves down, it also compresses the spring 13, causing the spring 13 to deform and generate elastic potential energy. When the ring plate 9 is released, the spring 13 stops being under force and releases the elastic potential energy, pushing the ring plate 9 up to return to its initial position.

[0025] like Figure 3 As shown, a second spring 14 is provided on the outer side of the connecting plate 6. The second spring 14 is fixedly connected to the connecting plate 6, and the end of the second spring 14 away from the connecting plate 6 is fixedly connected to the fixing plate 8.

[0026] To achieve the function of automatic reset after the baffle 4 moves, a second spring 14 is set between the connecting plate 6 and the fixed plate 8. When the baffle 4 moves, the baffle 4 will drive the connecting plate 6 to squeeze the second spring 14. At this time, the second spring 14 will deform under force and generate elastic potential energy. After the baffle 4 finishes moving, the second spring 14 will release the elastic potential energy and push the baffle 4 to reset through the connecting plate 6. At this time, the user does not need to move the baffle 4 separately, which improves the automation level of the device.

[0027] like Figure 2 and Figure 4 As shown, the storage bucket 3 has a slot 15 on its outer side, a locking rod 16 is slidably connected inside the ring plate 9, a pair of limiting rods 17 are fixedly connected to the outer side of the ring plate 9, and a fixing plate 18 is fixedly connected to the end of each pair of limiting rods 17 away from the ring plate 9. A sliding plate 19 is slidably connected to the outer side of the pair of limiting rods 17, and the sliding plate 19 is fixedly connected to the locking rod 16. A spring 20 is fixedly connected between the sliding plate 19 and the fixing plate 18.

[0028] When opening the baffle 4, the user needs to press the ring plate 9 throughout the process, which causes some inconvenience. In order to keep the baffle 4 continuously open, when the ring plate 9 is pressed during use, the ring plate 9 will drive the locking rod 16 and the limiting rod 17 to move down synchronously. At this time, the spring 20 is in a continuously compressed state. When the locking rod 16 moves down, it always follows the outer side of the storage bucket 3. When the locking rod 16 and the locking groove 15 are at the same horizontal height, the spring 20 releases its elastic potential energy instantly, pushing the locking rod 16 to move through the sliding plate 19. The ring plate 9 will then be inside the slot 15. At this time, the lever 16 is blocked by the slot 15 and cannot move up and down, thus limiting the ring plate 9. At this time, the user does not need to squeeze or press the ring plate 9. The ring plate 9 can remain stationary, freeing the user's hands and providing convenience. When the ring plate 9 needs to move up and down, simply pull the slide plate 19 away from the storage bin 3. At this time, the slide plate 19 drives the lever 16 to move. The lever 16 disengages from the slot 15, and the slot 15 stops blocking the lever 16, allowing the ring plate 9 to move.

[0029] like Figure 3 and Figure 4 As shown, a transparent glass 21 is installed on the outside of the storage bucket 3, and a rubber pad 22 is glued to the close ends of the pair of baffles 4.

[0030] The transparent glass 21 allows users to easily observe the storage status of plaster powder inside the storage bucket 3, so that plaster powder can be added in a timely manner. The rubber pad 22 reduces the impact force when the pair of baffles 4 re-engage, and increases the sealing of the bottom of the storage bucket 3 when the pair of baffles 4 are closed.

[0031] Working principle: Open the sealing cover 5 in advance, add plaster powder through the top of the storage bucket 3, and then close the sealing cover 5. At this time, in the subsequent operation of the sensor 2, the storage bucket 3 is filled with plaster powder, which can effectively avoid the situation of forgetting to bring plaster powder. When plaster powder needs to be added to the ground, the traction mechanism can pull a pair of connecting plates 6 to move away from the storage bucket 3. When the connecting plates 6 move, they will drive the baffles 4 to move simultaneously. At this time, the pair of baffles 4 open the bottom of the storage bucket 3, and the plaster powder inside the storage bucket 3 can fall under the action of gravity. The process is convenient and there is no possibility of forgetting to prepare plaster powder. When the plaster powder is added, the traction mechanism automatically resets and moves the pair of baffles 4 in the opposite direction to the initial position.

[0032] When the ring plate 9 is pressed down, the ring plate 9 will pull the traction rope 10. The traction rope 10 will be pulled by the force, which will pull the connecting plate 6. The connecting plate 6 will be moved along the outside of the limit rod 7, opening the seal at the bottom of the storage bucket 3. When the ring plate 9 moves down, the ring plate 9 will also squeeze the spring 13, causing the spring 13 to deform and generate elastic potential energy. When the ring plate 9 is released, the force on the spring 13 ends, and the elastic potential energy is released, pushing the ring plate 9 to move up and return to the initial position.

[0033] A second spring 14 is installed between the connecting plate 6 and the fixed plate 8. When the baffle 4 moves, the baffle 4 will drive the connecting plate 6 to squeeze the second spring 14. At this time, the second spring 14 will deform under the force and generate elastic potential energy. After the baffle 4 finishes moving, the second spring 14 will release the elastic potential energy and push the baffle 4 to reset through the connecting plate 6. At this time, the user does not need to move the baffle 4 separately, which improves the automation level of the device.

[0034] When opening the baffle 4, the user needs to press the ring plate 9 throughout the process, which causes some inconvenience. In order to keep the baffle 4 continuously open, when the ring plate 9 is pressed during use, the ring plate 9 will drive the locking rod 16 and the limiting rod 17 to move down synchronously. At this time, the spring 20 is in a continuously compressed state. When the locking rod 16 moves down, it always follows the outer side of the storage bucket 3. When the locking rod 16 and the locking groove 15 are at the same horizontal height, the spring 20 releases its elastic potential energy instantly, pushing the locking rod 16 to move through the sliding plate 19. The ring plate 9 will then be inside the slot 15. At this time, the lever 16 is blocked by the slot 15 and cannot move up and down, thus limiting the ring plate 9. At this time, the user does not need to squeeze or press the ring plate 9. The ring plate 9 can remain stationary, freeing the user's hands and providing convenience. When the ring plate 9 needs to move up and down, simply pull the slide plate 19 away from the storage bin 3. At this time, the slide plate 19 drives the lever 16 to move. The lever 16 disengages from the slot 15, and the slot 15 stops blocking the lever 16, allowing the ring plate 9 to move.

[0035] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
