Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic detectors, in particular to an ultrasonic detector that is easy to carry. Background Art

[0002] Ultrasonic detectors emit ultrasonic pulses into the water body and receive the signals reflected from the bottom of the water. They use the time difference of sound waves propagating in the medium to calculate the water depth. This not only avoids the water pollution or safety risks that may be caused by traditional contact measurements, but also ensures the accuracy and reliability of the measurement results. In the field of water conservancy projects, ultrasonic detectors are widely used for water depth monitoring of natural water bodies such as reservoirs, lakes, and rivers. By measuring water depth regularly or in real time, water conservancy engineers can timely understand the changes in water bodies, provide a scientific basis for flood control, irrigation, water resources scheduling, etc., and provide important reference for the planning, design and construction of water conservancy projects.

[0003] The existing patent (publication number: CN219349131U) discloses that "the utility model discloses a portable ultrasonic detector, which relates to the field of detection technology and includes an ultrasonic detector body, wherein the top of the ultrasonic detector body is fixedly connected to a fixed block, the top of the fixed block is movably connected to a positioning column, the top of the positioning column is fixedly connected to a fixed platform, the top of the fixed platform is fixedly connected to a protective shell, the top of the protective shell is fixedly connected to a fixing mechanism shell, the top of the fixing mechanism shell is fixedly connected to a servo motor, and the inner wall of the protective shell is slidably connected to a rack. The utility model fixes the fixed block by staggered insertion of two sliding rods into the interior of the fixed block. The staggered and tightened connection avoids the risk of the ultrasonic detector body falling off due to unstable connection. The water-proof cloth blocks water from entering the interior of the shock-absorbing mechanism shell to prevent the acceleration of rust of the shock-absorbing mechanism due to water intrusion. The presence of the water-proof cloth increases the life of the device."

[0004] In the process of implementing this application, the inventors discovered that the prior art has the following problems:

[0005] 1. This device uses a motor to drive the gear to rotate, prompting the fixing block to be inserted into the corresponding hole to fix the ultrasonic detector body. Although this method is effective, the overall cost is high, which increases the overall cost of the device.

[0006] 2. The device uses the interaction between the second spring and the waterproof cloth to achieve shock absorption through the second spring. However, the effect of this shock absorption method is poor. In complex and changeable underwater environments, especially when encountering large water flow impacts and water pressure changes, it cannot effectively alleviate the impact of underwater fluctuations, affecting the stability of the device and measurement accuracy.

[0007] Therefore, those skilled in the art provide a portable ultrasonic detector to solve the problems raised in the above background technology. Utility Model Content

The initial installation is achieved by inserting the connecting head into the connecting groove, and then rotating the connecting ring to make the connection between the connecting block and the detector body tighter.

[0009] To achieve the above objectives, the present invention provides the following technical solutions:

[0010] A portable ultrasonic detector includes a mounting block and a detector body, wherein a connecting block is slidably provided inside the mounting block near the lower end, a plurality of fixing holes are provided on the outside of the connecting block, a plurality of fixing posts are fixedly provided inside the mounting block near the upper end, a fixing plate is fixedly provided between the lower ends of the plurality of fixing posts, a plurality of buffer holes are provided inside the fixing plate, and a plurality of compression springs are fixedly provided at the lower end of the fixing plate;

[0011] An installation mechanism is provided inside the detector body, and the installation mechanism includes four first springs, four connecting ropes, four limit plates, a connector, four limit blocks, a connecting groove, four second springs and a pull ring. The outside of the detector body is threadedly connected to a connecting ring.

[0012] Furthermore, the four limit plates are rotatably arranged on opposite sides of two pairs at the lower end of the outside of the detector body, and the four first springs are fixedly arranged on opposite sides of two pairs at the upper end of the four limit plates, and the four first springs are fixedly arranged on opposite sides of two pairs at the upper end of the outside of the detector body.

[0013] Furthermore, the four limit blocks are rotatably arranged on opposite sides of each other on the outside of the connector near the lower end, and the four second springs are fixedly arranged on opposite sides of each other on the four limit blocks.

[0014] Furthermore, the four connecting ropes are fixedly arranged on opposite sides of the four limit blocks and the four limit plates, and the four second springs are fixedly arranged on opposite sides of the connector outside near the upper end.

[0015] Furthermore, the outsides of the four connecting ropes are slidably arranged inside the connector and the detector body, the lower ends of the four connecting ropes are fixedly arranged on the upper end of the pull ring, and the outside of the pull ring is slidably arranged at the lower end inside the detector body.

[0016] Furthermore, the internal thread of the connecting ring is connected to the detector body and the outside of the connecting block, the external sliding clamping of the connecting head is arranged inside the connecting groove, and the external connecting groove is opened at the lower end of the connecting block.

[0017] Furthermore, a sealing ring is fixedly provided at the lower end of the connecting block, and the lower end of the sealing ring is provided at the upper end of the detector body.

[0019] The utility model has the following beneficial effects:

[0020] 1. The utility model proposes a portable ultrasonic detector. When in use, the mounting block is fixed to the bottom of the hull and ensures that the position is appropriate. Then, the connecting head on the detector body is aligned with the connecting groove at the lower end of the connecting block and inserted. During the insertion process, the limit block will be squeezed by the connecting groove, causing the second spring to contract. When the connecting head is in place, the second spring rebounds, driving the limit block to rotate, thereby achieving a secure clamping of the connecting head. Then, the connecting ring is rotated to tightly connect the detector body and the connecting block through a thread, thereby enhancing the stability and sealing of the overall connection. When the connecting ring moves, the squeezing of the limit plate will be released, causing the first spring to rebound and drive the limit plate to rotate, which can prevent the connecting ring from moving accidentally. The limit plate, limit block and threaded connection can be used to achieve quick installation and disassembly, thereby improving work efficiency.

[0021] 2. The utility model proposes a portable ultrasonic detector. When the device is working in water, water will enter the connecting block and the mounting block through the fixing hole. When the device is subjected to water fluctuations, the detector body and the connecting block move synchronously, causing the connecting block to slide inside the mounting block, driving the fixing hole to move upward synchronously, and squeezing the compression spring, causing the fixing plate and the sealing ring to slide inside the connecting block, resulting in the water on the upper end of the connecting block being squeezed, causing the water on the connecting block to slowly flow into the mounting block through the buffer hole in the fixing plate, thereby alleviating the external force and realizing shock absorption operation. At the same time, the movement of the connecting block will create a gap between the mounting block and the connecting block, causing the water inside the mounting block to flow out through the gap, so that it can provide accurate and reliable measurement data in water conservancy projects and improve the stability of detection.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1-7 , an embodiment provided by the utility model:

[0033] A portable ultrasonic detector includes a mounting block 1 and a detector body 4. A mounting mechanism 6 is provided inside the detector body 4. The mounting mechanism 6 includes four first springs 601, four connecting ropes 602, four limit plates 603, a connector 604, four limit blocks 605, a connecting groove 606, four second springs 607 and a pull ring 608. The external thread of the detector body 4 is connected to a connecting ring 5. The four limit plates 603 are rotatably arranged on the outer side of the detector body 4 near the lower end on two opposite sides. The four first springs 601 are fixedly arranged on the four limit plates 603 on the upper end on two opposite sides. The four first springs 601 are fixedly arranged on the outer side of the detector body 4 near the upper end on two opposite sides. The four limit blocks 605 are rotatably arranged on the outer side of the connector 604 near the lower end on two opposite sides. The second springs 607 are fixed on opposite sides of two pairs of the four limit blocks 605, and the four second springs 607 are fixed on the upper end of the outer side of the connecting head 604. The four connecting ropes 602 are fixed on opposite sides of two pairs of the four limit blocks 605 and the four limit plates 603. The outer sides of the four connecting ropes 602 are slidably arranged on the connecting head 604 and the inside of the detector body 4. The lower ends of the four connecting ropes 602 are fixed on the upper end of the pull ring 608, and the outer side of the pull ring 608 is slidably arranged on the lower end of the inner side of the detector body 4. The inner side of the connecting ring 5 is threadedly connected to the detector body 4 and the outer side of the connecting block 3. The outer side of the connecting head 604 is slidably engaged with the inner side of the connecting groove 606. The outer side of the connecting groove 606 is opened at the lower end of the connecting block 3, and the lower end of the detector body 4 is slidably provided with a sliding cover 7.

[0034] Specifically, when using the device, first fix the mounting block 1 to a suitable position on the bottom of the hull, then accurately align the connector 604 of the detector body 4 and insert it into the connecting groove 606 at the lower end of the connecting block 3. As the connector 604 goes deeper into the connecting groove 606, the external limit block 605 will gradually be subjected to lateral pressure from the connecting groove 606, causing the second spring 607 connected to the limit block 605 to produce compression deformation. When the connector 604 completely reaches the terminal position of the connecting groove 606, the connecting groove 606 will stop pressing the limit block 605 and The second spring 607 is squeezed, and the second spring 607 rebounds quickly, driving the limit block 605 to complete the rotation action outside the connector 604, so that the connector 604 is firmly clamped in the connecting groove 606, completing the initial quick installation, saving time and effort, and low cost. Then, by rotating the connecting ring 5 on the periphery of the detector body 4, the upward movement of the connecting ring 5 is achieved by interacting with the threads on the outside of the detector body 4 and the connecting block 3. This process not only enhances the connection tightness between the detector body 4 and the connecting block 3, but also through the sealing ring 8 The sealing performance of the connection is further improved, and it is easy to carry and install, and the convenience of use is improved. As the connecting ring 5 rotates and rises, it will gradually release the locking state of the limit plate 603, so that the first spring 601 connected to the limit plate 603 can release energy, and then push the limit plate 603 to rotate, so that it can effectively limit the connecting ring 5, prevent it from accidentally sliding down, avoid the risk of the device loosening and falling off, improve the stability of the connection, and simplify the installation and disassembly process, improve the convenience of on-site operation, the detector body 4 has The waterproof performance can adapt to various harsh water environments. When disassembling, the sliding cover 7 at the lower end of the detector body 4 is slid open, and then the pull ring 608 at the lower end of the detector body 4 is pulled to make the connecting rope 602 slide, thereby driving the limit plate 603 and the limit block 605 connected thereto to rotate. When the two rotate, the first spring 601 and the second spring 607 are compressed. Subsequently, the connecting ring 5 is rotated in the opposite direction to release the connection between the connecting block 3 and the detector body 4, thereby realizing quick disassembly, convenient operation, and improved work efficiency.

[0035] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 5, a connecting block 3 is slidingly provided inside the mounting block 1 near the lower end, a plurality of fixing holes 2 are opened on the outside of the connecting block 3, a plurality of fixing columns 12 are fixedly provided on the upper end of the mounting block 1, a fixing plate 10 is fixedly provided between the lower ends of the plurality of fixing columns 12, a plurality of buffer holes 11 are opened inside the fixing plate 10, a plurality of compression springs 13 are fixedly provided on the lower end of the fixing plate 10, a sealing ring 8 is fixedly provided on the lower end of the connecting block 3, the lower end of the sealing ring 8 is set on the upper end of the detector body 4, the lower ends of the plurality of compression springs 13 are fixedly set on the upper end of the connecting block 3, a sealing ring 9 is fixedly provided on the outside of the fixing plate 10, the sealing ring 9 is slidingly provided on the outside of the connecting block 3, and the fixing plate 10 is slidingly provided on the outside of the connecting block 3;

[0036] Specifically, when the device is working underwater, water will flow into the top of the connecting block 3 and the internal space of the mounting block 1 through the fixing hole 2 on the connecting block 3. If the device encounters vibrations caused by water flow fluctuations, the detector body 4 will drive the closely connected connecting block 3 to slide upward along the inside of the mounting block 1. The sliding of the connecting block 3 not only drives the fixing hole 2 to move upward, but also squeezes the compression spring 13 connected to it, causing it to shrink, and at the same time prompting the fixing plate 10 and the sealing ring 9 to slide in the connecting block 3, thereby compressing the water inside the connecting block 3, so that this part of the water is slowly released into the inside of the mounting block 1 through the buffer hole 11 on the fixing plate 10, thereby effectively buffering the external impact force. At the same time, the gap between the connecting block 3 and the mounting block 1 caused by sliding allows the water inside the mounting block 1 to be discharged smoothly, so that the detector body 4 remains stable in the fluctuating water environment, reduces the measurement error caused by vibration, and improves the detection accuracy and efficiency.

[0037] When the locking nut 605 is unlocked, the locking nut 606 is engaged with the locking nut 607, and the locking nut 607 is engaged with the locking nut 608. When the connecting ring 5 is rotated on the outside of the detector body 4, it will gradually connect with the thread on the outside of the connecting block 3, so that the connection between the detector body 4 and the connecting block 3 is tighter, and the sealing ring 8 can strengthen the tightness of the connection between the two. When the connecting ring 5 is rotated and moved upward, it will gradually release the pressure on the limit plate 603, causing the first spring 601 connected to the limit plate 603 to rebound, thereby causing the limit plate 603 to rotate, thereby limiting the connecting ring 5 and preventing it from moving downward. When disassembling, the sliding cover 7 at the lower end of the detector body 4 is slid, and then the pull ring 608 is pulled, so that the connecting rope 602 slides inside the connector 604 and the detector body 4, thereby causing the limit plate 603 and the limit block 605 connected to the connecting rope 602 to rotate and squeeze the first spring 601 and the second spring 607. Then, the connecting ring 5 is rotated to release the connection between the detector body 4 and the connecting block 3.

[0038] When the water level rises, the water level rises, and the water level rises, and the water level rises, and the water level rises, and the water level rises, and the water level rises. When the water level rises, the water level rises, and the water level rises, the water level rises, and the water level rises. When the water level rises, the water level rises, and the water level rises.
