Description

Technical Field

[0001] This utility model relates to the field of LNG transportation safety detection technology, specifically to an LNG transportation safety detection device. Background Technology

[0002] As one of the main energy sources, LNG plays a vital role in transportation, heating and power generation, and industrial production. However, LNG has a low boiling point and low temperature, and it is easy to evaporate quickly and form a flammable and explosive mixture. Therefore, there are significant safety hazards during transportation and storage. To ensure the safety of LNG transportation, reliable LNG transportation safety detection devices are needed.

[0003] In existing technologies, detection devices are installed around LNG transport tanks. Leak detection sensors and flame sensors installed on the top of the devices monitor the area around the tank in real time to prevent gas leaks and fires. However, in actual use, the device directly fixes the mounting plates of the leak detection sensors and flame sensors to the tank with bolts. This requires constant tightening of bolts during maintenance, making it inconvenient for workers to quickly disassemble and remove the mounting plates of the flame detection sensors and leak detection sensors, thus increasing the workload for workers. In addition, the sensors do not have protective shock-absorbing structures on their exteriors during daily use. As a result, airborne debris and vibrations from bumpy roads during transportation can easily increase the probability of sensor damage. Therefore, there is a need to improve the LNG transport safety detection device. Utility Model Content

[0013] Preferably, the bottom of the cover plate has a groove, and the size of the locking block is the same as the groove, which facilitates quick disassembly later.

[0014] Compared with the prior art, this utility model provides an LNG transportation safety detection device, which has the following beneficial effects:

[0015] 1. This LNG transportation safety detection device, through its quick-release protective mechanism and the shielding plate on top of its sensor, further avoids the risk of airborne debris hitting the sensor. At the same time, when disassembly and maintenance are required later, the shielding plate can be manually pushed and the mounting plate can be manually pulled upwards to quickly separate the mounting plate from the fixed base. This allows the leak detection sensor and flame detector on the mounting plate to be quickly separated from the main body of the device, facilitating rapid disassembly and making it easier for staff to carry out subsequent inspection and maintenance, thereby reducing the tediousness of the work.

[0016] 2. This LNG transportation safety detection device, through its shock-absorbing mechanism, uses the energy generated by the bumps to cause the damper to contract, which in turn compresses the spring, which in turn pushes the connecting rod to move. The connecting rod then pushes the slider to move, and the damper absorbs the energy generated by the vibration, thereby maximizing the protection of the sensor and reducing the risk of sensor damage due to vibration.

[0028] Example 1:

[0029] Based on existing technology, this device directly bolts the mounting plates of the leak detection sensor and the flame sensor to the transport tank. This requires constant tightening of the bolts during maintenance, making it difficult for workers to quickly disassemble both the flame detection sensor and the leak detection sensor mounting plates simultaneously, increasing the workload. Furthermore, the lack of external protection for the sensors during daily use means that airborne debris during transport can easily damage them. For further information, please refer to [link to relevant documentation]. Figure 1-5 This utility model provides a technical solution: an LNG transportation safety detection device, including an LNG transport tank 1, a support 2 fixedly connected to the bottom of the LNG transport tank 1, a connecting frame 3 fixedly connected to the front and rear inner sides of the support 2, a shock-absorbing mechanism 5 set outside the connecting frame 3, a quick-release protection mechanism 4 set at the top of the shock-absorbing mechanism 5, a leak detection sensor 6 set outside the quick-release protection mechanism 4, and a flame detector 7 set outside the quick-release protection mechanism 4.

[0030] The quick-release protective mechanism 4 includes a quick-release component 41 and a protective component 42, with the protective component 42 located on top of the quick-release component 41.

[0031] Furthermore, the quick-release assembly 41 includes a fixing base 411, which is fixedly connected to the top of the connecting frame 51. A locking block 412 is slidably connected inside the fixing base 411. A pull rod 413 is fixedly connected to the right side of the locking block 412. A spring 414 is fixedly connected between the locking block 412 and the fixing base 411. A wedge block 415 is fixedly connected to the bottom of the locking block 412. A slidable push block 416 is slidably connected inside the fixing base 411. A spring 417 is fixedly connected between the fixing base 411 and the slidable push block 416. A locking frame 419 is inserted inside the fixing base 411. A mounting plate 418 is fixedly connected to the top of the locking frame 419, which facilitates the quick disassembly of the leak detection sensor and the flame sensor mounting plate 418 for easy daily maintenance.

[0032] Furthermore, slots are provided at the corresponding positions of the card frame 419 and the inclined push block 416, and the inclined push block 416 is inserted into the slot. The fixing seat 411 is slidably connected to the inner side of the connecting frame 3 to facilitate fixing the card frame 419.

[0033] Furthermore, the bottom inclined surface of the inclined block 415 abuts against the front inclined surface of the inclined push block 416, and the fixing base 411 and the corresponding position of the card frame 419 are provided with a groove, and the card frame 419 is inserted into the groove, so as to facilitate pushing the inclined push block 416 to be locked inside the card frame 419.

[0034] Furthermore, the protective component 42 includes a fixing frame 421, which is fixedly connected to the top of the fixing base 411. A guide post 423 is fixedly connected to the outside of the fixing frame 421, and a cover plate 424 is slidably connected to the outside of the guide post 423. A spring 422 is fixedly connected between the cover plate 424 and the fixing frame 421 to facilitate protection during the use of the device.

[0035] Furthermore, the bottom of the cover plate 424 is provided with a groove, and the size of the locking block 412 is the same as the groove, which facilitates quick disassembly later.

[0036] Example 2:

[0037] Based on current technology, none of the sensors have external shock-absorbing structures. Therefore, during transportation, vibrations from bumpy roads can easily increase the probability of sensor damage. Please refer to [link to relevant documentation]. Figure 5 Furthermore, in conjunction with Embodiment 1, it is further found that the shock-absorbing mechanism 5 includes a damper 55, which is fixedly connected to the top of the connecting frame 3. A connecting frame 51 is fixedly connected to the top of the damper 55. A spring 54 is fixedly connected between the connecting frame 51 and the connecting frame 3. A connecting rod 52 is rotatably connected to the inner front and rear sides of the connecting frame 51. A slider 53 is rotatably connected to the end of the connecting rod 52 away from the connecting frame 51. A spring 4 56 is fixedly connected between the slider 53 and the connecting frame 3, which facilitates a buffering effect during transportation, thereby protecting the flame detector 7 and the leak detection sensor 6.

[0038] Furthermore, a groove is provided at the corresponding position of the connecting frame 3 and the slider 53, and the slider 53 is slidably connected in the groove to facilitate its supporting function.

[0039] In actual operation, when the device is in use, firstly, its leak detection sensor and flame detector 7 are installed on both sides of the LNG transport tank 1. The leak detection sensor uses high-sensitivity gas detection technology, such as infrared absorption and laser beam detection, to monitor LNG leaks in real time. Once an LNG leak is detected, an alarm is immediately triggered so that emergency measures can be taken promptly. The flame detector 7 is equipped with ultraviolet and infrared spectral detection functions, which can accurately identify the spectral characteristics of flame combustion. During transportation, when encountering bumpy sections, the damping mechanism 5 absorbs the energy from the bumps, causing the damper 55 to contract, which in turn compresses the spring 54, thus simultaneously pushing the connecting rod 52 to move. The connecting rod 52 then pushes the slider 53 to move, and the damper 55 absorbs the energy from the vibration, thereby maximizing the protection of the sensor. Simultaneously, during transportation, the quick-release protective mechanism 4 allows the sensor to... The top-mounted cover plate 424 further avoids the risk of airborne debris hitting the sensor. When disassembly and maintenance are required later, the cover plate 424 can be manually pushed closer to the mounting bracket 421, allowing it to move along the guide post 423. When the groove at the bottom of the cover plate 424 aligns with the locking block 412, the locking block 412 engages with the groove under the force of spring 414. This simultaneously moves the inclined block 415 upwards, and the inclined push block 416, under the force of spring 417, keeps its inclined surface in contact with the inclined surface of the inclined block 415, preventing it from contacting the mounting frame 419 during movement. Then, the mounting plate 418 can be manually pulled upwards to quickly separate from the mounting base 411, allowing the leak detection sensor 6 and flame detector 7 on the mounting plate 418 to be quickly separated from the main body of the device.
