Description

Technical Field

[0001] This utility model belongs to the field of inspection equipment technology, specifically relating to an intelligent robot inspection device for LNG receiving stations. Background Technology

[0002] Liquefied natural gas (LNG) receiving terminals are a crucial link in the natural gas industry chain, responsible for receiving, storing, and transferring LNG and supplying it to cities, industries, and power generation needs through processes such as vaporization. However, LNG receiving terminals involve complex equipment and pipeline systems, especially when operating under extreme conditions such as high pressure, high temperature, and low temperature. The requirements for equipment inspection and maintenance are extremely stringent. Therefore, adopting advanced intelligent inspection technology to improve the safety and efficiency of LNG receiving terminals has become an urgent need for the industry's development.

[0003] The existing technology includes a multi-functional track inspection trolley with patent publication number CN214689470U. This patent includes a vehicle body and wheels mounted on the underside of the vehicle body. A cavity is formed on the upper side of the vehicle body, and a chassis is located on one side of the cavity. The chassis houses a battery, a microcomputer, and a wireless communication module. A display is embedded on the upper side of the chassis, a control panel is located on one side of the display, a data port is located on one side of the control panel, and a drive base is located on one side of the cavity… This device uses a track trolley with a drive system, which can be freely and flexibly placed on the track for inspection. The cavity on the upper side of the trolley facilitates the placement of tools or replacement parts by maintenance personnel, making it more convenient and efficient to use. However, in practical use, the following shortcomings still exist: From a practical standpoint, this device lacks a protective mechanism for the camera. When the inspection trolley is not in use, the camera is exposed, easily accumulating dust and affecting its clarity. Due to unpredictable external factors, the camera is easily damaged, which is detrimental to the long-term use of the inspection trolley.

[0004] Therefore, there is a need for an intelligent robotic inspection device for LNG receiving terminals to solve the problem that the lack of protection measures for cameras in existing technologies is not conducive to the long-term use of inspection devices. Utility Model Content

[0005] The purpose of this invention is to provide an intelligent robotic inspection device for LNG receiving stations to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an intelligent robot inspection device for LNG receiving stations, comprising a drive base, multiple drive wheels mounted on the bottom of the drive base, a protective box fixedly connected to the top of the drive base, a flip-top mechanism on the top of the protective box, two electric telescopic rods fixedly connected to the upper surface of the bottom of the protective box, an installation platform fixedly connected to the top of the two electric telescopic rods, two cameras mounted on the top of the installation platform, a second support plate fixedly connected to the rear end of the drive base, a fire extinguisher box fixedly connected to the top of the second support plate, conveying pipes fixedly connected to both sides of the fire extinguisher box, stabilizing blocks corresponding to the conveying pipes fixedly connected to both sides of the protective box, and nozzles fixedly connected to the front ends of the two conveying pipes.

[0007] It should be noted in the solution that the outer surfaces of the multiple drive wheels are all fixedly connected with evenly distributed anti-slip strips.

[0008] It is further worth noting that the flip-top mechanism includes two first support plates fixedly connected to the inner surface of the rear end of the protective box. Both first support plates have bifurcated arc grooves inside. A round rod is slidably connected between the two first support plates near the bottom. Two Z-shaped plates are fixedly connected to the outer wall of the round rod. A connecting seat is fixedly connected to the top of each of the two Z-shaped plates. A top cover is fixedly connected to the top of each of the two connecting seats. A pin is fixedly connected to the outer side of each of the two Z-shaped plates. A first connecting rod is rotatably connected to the outer wall of the round rod. A second connecting rod is rotatably connected to the outer side of the first connecting rod. A servo motor corresponding to the second connecting rod is fixedly connected to the outer side of the protective box.

[0009] It should be further noted that both the round rod and the pin slide on the inner wall of the bifurcated arc groove.

[0010] In a preferred embodiment, the output end of the servo motor is fixedly connected to the second connecting rod.

[0011] In a preferred embodiment, both cameras are rotatably mounted on the top of the mounting platform.

[0012] In a preferred embodiment, both delivery pipes pass through the inner wall of the stabilizing block, and both nozzles are equipped with electromagnetic control valves.

[0013] Compared with the prior art, the intelligent robotic inspection device for LNG receiving stations provided by this utility model has at least the following beneficial effects:

[0014] (1) By setting up a protective box and a flip-top mechanism, when in use, the servo motor is turned on to drive the second connecting rod to rotate, and the second connecting rod drives the first connecting rod to move upward, so that the round rod drives the Z-shaped plate to rise, and the Z-shaped plate pushes the top cover to rise. When the pin reaches the top of the bifurcated arc groove, the pin becomes a temporary rotating rod, and the top cover changes from rising motion to rotating motion, completing the automatic opening of the top cover. Then, the electric telescopic rod is opened to drive the two cameras to rise for inspection work. When the device is not in use, the servo motor drives the second connecting rod to rotate in the opposite direction to automatically close the top cover. The protective box and the top cover form a sealed space to protect the cameras, so that the cameras are not affected by external environments such as dust, pollution, and mechanical damage, thereby extending the service life of the equipment.

[0015] (2) By setting up fire boxes, delivery pipes and nozzles in combination, the camera can monitor potential fires or other dangers in the LNG receiving station in real time. Once a danger is detected, the control system will automatically start the solenoid valve and quickly open the nozzle to extinguish the fire. This can extinguish the fire source in the shortest time and significantly reduce the risk of the danger spreading. Attached Figure Description

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Please see Figure 1-4This utility model provides an intelligent robot inspection device for LNG receiving stations, including a drive base 1, multiple drive wheels 2 installed at the bottom of the drive base 1, a protective box 3 fixedly connected to the top of the drive base 1, a flip-top mechanism 4 on the top of the protective box 3, two electric telescopic rods 5 fixedly connected to the bottom upper surface of the protective box 3, a mounting platform 6 fixedly connected to the top of the two electric telescopic rods 5, two cameras 7 installed on the top of the mounting platform 6, a second support plate 8 fixedly connected to the rear end of the drive base 1, a fire box 9 fixedly connected to the top of the second support plate 8, conveying pipes 10 fixedly connected to both sides of the fire box 9, stabilizing blocks 11 corresponding to the conveying pipes 10 fixedly connected to both sides of the protective box 3, and nozzles 12 fixedly connected to the front ends of the two conveying pipes 10.

[0023] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the outer surfaces of multiple drive wheels 2 are fixedly connected with evenly distributed anti-slip strips, which increases the friction between the outer wall of the drive wheel 2 and the ground, enabling the drive wheel 2 to adapt to various complex road conditions.

[0024] Further as Figure 3 As shown, it is worth noting that both cameras 7 are rotatably mounted on the top of the mounting platform 6. This rotatable mounting allows each camera 7 to rotate within a wider range, thereby covering more areas and improving the inspection range and monitoring capabilities. The cameras 7 can automatically adjust their viewing angles as needed during the robot's inspection process to ensure there are no blind spots.

[0025] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that both delivery pipes 10 pass through the inner wall of the stabilizing block 11, which helps to fix and stabilize the position of the delivery pipes 10, preventing shaking or displacement during operation and ensuring the safety and stability of the system. In addition, both nozzles 12 are equipped with electromagnetic control valves. The use of electromagnetic control valves can realize remote control or automated operation, reducing the need for manual intervention. This allows the LNG receiving station inspection device to perform its tasks more efficiently and accurately, especially in complex or dangerous environments, reducing the risk of manual operation.

[0026] As can be seen from the above working process, by setting up fire box 9, delivery pipe 10 and nozzle 12 in coordination, camera 7 can monitor potential fires or other dangers in the LNG receiving station in real time. Once a danger is detected, the control system will automatically activate the solenoid valve and quickly open the nozzle 12 to extinguish the fire, which can extinguish the fire source in the shortest time and significantly reduce the risk of the danger spreading.

[0027] Further as Figure 4As shown, it is worth noting that the flip-top mechanism 4 includes two first support plates 401 fixedly connected to the inner surface of the rear end of the protective box 3. Each of the two first support plates 401 has a forked arc groove 402 inside. A round rod 403 is slidably connected between the two first support plates 401 near the bottom. Two Z-shaped plates 404 are fixedly connected to the outer wall of the round rod 403. Connecting seats 405 are fixedly connected to the top of each of the two Z-shaped plates 404. A top cover 406 is fixedly connected to the top of each of the two connecting seats 405. Pins 407 are fixedly connected to the outer sides of each of the two Z-shaped plates 404. The outer wall of the round rod 403... A first connecting rod 408 is rotatably connected, and a second connecting rod 409 is rotatably connected to the outside of the first connecting rod 408. A servo motor 410 corresponding to the second connecting rod 409 is fixedly connected to the outside of the protective box 3. By setting the protective box 3 and the flip-top mechanism 4 to cooperate, when the device is not in use, the servo motor 410 drives the second connecting rod 409 to rotate in the opposite direction to automatically close the top cover 406. The protective box 3 and the top cover 406 form a sealed space to protect the camera 7, so that the camera 7 is not affected by external environmental factors such as dust, pollution, and mechanical damage, thereby extending the service life of the device.

[0028] Further as Figure 4 As shown, it is worth noting that both the round rod 403 and the pin 407 slide on the inner wall of the bifurcated arc groove 402, which ensures that the movement paths of the round rod 403 and the pin 407 remain stable during operation, reducing any unnecessary deviations and thus improving the stability and accuracy of the equipment.

[0029] Further as Figure 4 As shown, it is worth noting that the output end of the servo motor 410 is fixedly connected to the second connecting rod 409, ensuring that the servo motor 410 can drive the second connecting rod 409 to rotate smoothly, thereby providing driving force for the closing and opening of the top cover 406.

[0030] This solution has the following working process: In actual use, the servo motor 410 is turned on to drive the second connecting rod 409 to rotate. The second connecting rod 409 drives the first connecting rod 408 to move upward, thereby causing the round rod 403 to drive the Z-shaped plate 404 to rise. The Z-shaped plate 404 pushes the top cover 406 to rise. When the pin 407 reaches the top of the bifurcated arc groove 402, the pin 407 becomes a temporary rotating rod, and the top cover 406 changes from rising motion to rotating motion, completing the automatic opening of the top cover 406. Then, the electric telescopic rod 5 is opened to drive the two cameras 7 to rise for inspection work. When the device is not in use, the servo motor 410 drives the second connecting rod 409 to rotate in the opposite direction to automatically close the top cover 406. The protective box 3 and the top cover 406 form a sealed space to protect the cameras 7. When the cameras 7 detect danger, the control system automatically starts the solenoid valve and quickly opens the nozzle 12 to extinguish the fire.

[0031] In summary: By cooperating with the protective box 3 and the flip-top mechanism 4, when the device is not in use, the servo motor 410 drives the second connecting rod 409 to rotate in the opposite direction, automatically closing the top cover 406. The protective box 3 and the top cover 406 form a sealed space to protect the camera 7, preventing it from being affected by external environmental factors such as dust, pollution, and mechanical damage, thereby extending the service life of the equipment. By cooperating with the fire box 9, the delivery pipe 10, and the nozzle 12, the camera 7 can monitor potential fires or other hazards in the LNG receiving station in real time. Once a hazard is detected, the control system will automatically activate the solenoid valve and quickly open the nozzle 12 to extinguish the fire, which can extinguish the fire source in the shortest possible time and significantly reduce the risk of the hazard spreading.
