Description

Technical Field

[0001] This utility model relates to the field of station inspection technology, and in particular to a station inspection robot with an explosion-proof structure. Background Technology

[0002] The gas used in gas stations is mostly flammable and explosive. If it leaks and mixes with air to a certain concentration, it may cause an explosion or fire when it comes into contact with a source of ignition, seriously threatening the lives of people and the safety of facilities.

[0003] Therefore, daily inspections of the stations are necessary. Currently, station inspections are mainly conducted by inspectors using their senses (smell, hearing, touch, and sight) and by using handheld devices to check for gas leaks. Manual inspections have many inherent drawbacks, such as high labor intensity and low inspection efficiency. Utility Model Content

[0004] To address the technical problems of high labor intensity and low inspection efficiency in manual site inspections in existing technologies, this utility model provides a site inspection robot with an explosion-proof structure.

[0005] The site inspection robot with an explosion-proof structure provided by this utility model adopts the following technical solution: A site inspection robot with an explosion-proof structure includes a body and a leak detection structure installed in the body. A track assembly is located at the bottom of the body, and a camera is located at the front of the body. The leak detection structure includes a laser gas sensor located at the top of the body and a gas storage tank located inside the body. An explosion-proof structure for extinguishing open flames is located at the bottom of the body.

[0006] By adopting the above technical solution: during station inspections, the laser gas sensor in the leak detection structure is used to detect whether there is a gas leak, and the leaked gas is stored in a gas storage tank. The explosion-proof structure at the bottom of the fuselage is used to extinguish any open flames generated after an explosion of the fuselage.

[0007] Furthermore, the fuselage is a thickened cast metal shell.

[0008] By adopting the above technical solution, the strength of the fuselage is increased, preventing the fuselage from cracking.

[0009] Furthermore, a connecting plate is provided at the bottom of the machine body, on which a track assembly that drives the machine body to move is mounted, and a motor that drives the track assembly to rotate is also provided on the connecting plate.

[0010] By adopting the above technical solution, the machine body is moved to the position where it needs to be inspected by rotating the track assembly driven by a motor.

[0011] Furthermore, a lighting lamp is installed on the front side of the fuselage to provide illumination.

[0012] By adopting the above technical solution, the camera can work in low-light environments.

[0013] Furthermore, a battery is located at a lower position inside the fuselage, and a circuit board is located above the battery. The battery is electrically connected to the circuit board, and the circuit board is electrically connected to the track assembly.

[0014] By adopting the above technical solution: the inspection robot is powered by a battery, and the operation of the track assembly and other components in the inspection robot is controlled by a circuit board.

[0015] Furthermore, an air inlet is provided on the top of the fuselage, which is connected to an air tank, and an air pump is provided between the air inlet and the air tank. By adopting the above technical solution, the leaked gas is drawn into the gas storage tank by an air pump.

[0016] Furthermore, the explosion-proof structure includes a storage component and a flame-retardant component for extinguishing open flames.

[0017] By adopting the above technical solution, when a deflagration occurs inside the fuselage, the flame-retardant gas in the flame-retardant component can be ejected from the storage component and extinguish the open flame through the flame-retardant gas.

[0018] Furthermore, the storage assembly includes a housing fixed to the bottom of the body, an opening at the top of the housing, and exhaust pipes on both sides of the housing.

[0019] By adopting the above technical solution, the flame-retardant gas is discharged outward through the exhaust pipes on both sides of the box to extinguish the open flame.

[0020] Furthermore, the flame-retardant component includes a pressure plate and a glass jar. The pressure plate is longitudinally movable on the top opening of the box. A positioning post is located at the bottom of the pressure plate. The positioning post extends downward after passing through the bottom of the box. A spring is sleeved on the outside of the positioning post. One end of the spring abuts against the bottom of the pressure plate, and the other end contacts the bottom wall of the box. Under the elastic force of the spring, an explosion-proof space is formed between the pressure plate and the bottom wall of the box. The glass jar is placed in the explosion-proof space. The glass jar contains carbon dioxide that can extinguish open flames.

[0021] By adopting the above technical solution, the glass jar can be crushed by moving the pressure plate downwards, causing the carbon dioxide gas inside the glass jar to be ejected outwards through the exhaust pipe, thus extinguishing the open flame.

[0022] Furthermore, the bottom of the fuselage has an explosion-proof window that extends into the interior of the fuselage at a position corresponding to the pressure plate. The pressure plate is pressed against the outer wall of the explosion-proof window at the bottom of the fuselage by the elastic force of the spring, and the explosion-proof window is sealed.

[0023] By adopting the above technical solution: when an explosion occurs inside the fuselage, the impact force of the explosion causes the pressure plate to move downward, crushing the glass can and causing the carbon dioxide gas inside the glass can to be ejected outward through the exhaust pipe, extinguishing the open flame.

[0024] In summary, the beneficial effects of this utility model are as follows: 1. This utility model, by incorporating a leak detection structure, allows the robot to detect gas leaks in its surroundings using a laser gas sensor during site inspections. Upon detection, a camera captures a photograph of the leak location. If the location is dimly lit, illumination is provided, ensuring the robot is unaffected by lighting conditions and can be used at night. After a leak is detected, an air pump draws the leaked gas into a storage tank for later analysis of parameters such as gas concentration. This invention eliminates the need for manual inspections, reducing workload and increasing efficiency.

[0025] 2. The body of this utility model is made of thickened cast metal and is equipped with an explosion-proof structure. When an explosion occurs inside the body, the body will not be cracked. Under the impact of the explosion, the pressure plate at the bottom of the explosion-proof window in the body moves downward, crushing the glass canister in the explosion-proof structure. The carbon dioxide inside the glass canister is then ejected outward through the exhaust pipe to extinguish the open flame in the body and prevent it from causing a deflagration in the surrounding environment. This utility model has a strong explosion-proof effect and can be used in various testing environments. Attached Figure Description

[0028] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0029] Example: Figures 1-4 The image shows a site inspection robot with an explosion-proof structure.

[0030] Reference Figures 1-3 As shown, this utility model discloses a site inspection robot with an explosion-proof structure, including a body 1 and a leak detection structure installed in the body 1. The body 1 is a thickened cast metal shell, giving it sufficient strength to prevent the body 1 from shattering in the event of an internal explosion, thus avoiding an explosion of external flammable gases. A connecting plate 11 is located at the bottom of the body 1, and a track assembly 12 for moving the body 1 is mounted on the connecting plate 11. A motor for driving the track assembly 12 to rotate is also located on the connecting plate 11. A camera 2 and a lighting lamp 3 are located at the front of the body 1. During use, the camera 2 takes pictures of the leak location, and the lighting lamp 3 provides illumination when the location is dark. A battery 13 is located at the lower part of the body 1 to power the inspection robot. A circuit board 10 is located above the battery 13 to control the operation of various components of the inspection robot. The battery 13 is electrically connected to the circuit board 10, and the circuit board 10 is electrically connected to the track assembly 12. The battery powers the inspection robot, and the circuit board controls the operation of the track assembly and other components in the inspection robot.

[0031] The leak detection structure includes a laser gas sensor 5 installed on the top of the fuselage 1 and a gas storage tank 8 installed inside the fuselage 1. The laser gas sensor 5 detects gas at the inspection location. When a gas leak is detected, the camera 2 takes a picture of the leak location and records it. An air inlet 6 is installed on the top of the fuselage 1 and is connected to the gas storage tank 8. An air pump 61 is installed between the air inlet 6 and the gas storage tank 8. The air pump 61 draws external gas into the gas storage tank 8 for storage.

[0032] Reference Figures 3-4As shown, an explosion-proof structure 9 is provided at the bottom of the fuselage 1. The explosion-proof structure 9 includes a storage component and a flame-retardant component for extinguishing open flames. The storage component includes a box 91 fixedly installed at the bottom of the fuselage 1. The box 91 has an opening at the top and exhaust pipes 93 on both sides of the box 91. The flame-retardant component includes a pressure plate 92 and a glass jar 95. The pressure plate 92 is longitudinally movably installed on the opening at the top of the box 91. Preferably, a positioning post 94 is located at the bottom of the pressure plate 92. The positioning post 94 extends downward after passing through the bottom of the box 91. A spring 941 is sleeved on the outside of the positioning post 94. One end of the spring 941 abuts against the bottom of the pressure plate 92, and the other end contacts the bottom wall of the box 91. Under the elastic force of the spring 941, an explosion-proof space is formed between the pressure plate 92 and the bottom wall of the box 91. The glass jar 95 is placed in the explosion-proof space. The glass jar 95 contains carbon dioxide to extinguish open flames. The bottom of the fuselage 1 has an explosion-proof window 14 that extends into the interior of the fuselage 1, corresponding to the position of the pressure plate 92. The pressure plate 92 is pressed against the outer wall of the explosion-proof window 14 at the bottom of the fuselage 1 by the elastic force of the spring 941, thus sealing the explosion-proof window 14. When a deflagration occurs inside the fuselage 1, the pressure plate 92 moves downward under the impact force and presses the spring 941 downward. Under the pressure of the pressure plate 92, the glass canister 95 breaks, and the carbon dioxide inside the glass canister 95 is ejected outward through the exhaust pipe 93 to extinguish the open flame in the fuselage 1.

[0033] When using this invention for site inspection, the track assembly 12 is controlled by the circuit board 10 to move the inspection robot to the location to be inspected. The laser gas sensor 5 detects the air around the robot body 1. When a gas leak is detected, the camera 2 takes a picture of the leak location. If the light at the photo location is dim, the lighting lamp 3 provides illumination. Therefore, this inspection robot is not affected by light and can be used at night. After a gas leak is detected, the leaking gas is sucked into the gas storage tank 8 by the air pump 61 for storage, so that parameters such as the concentration of the leaking gas can be analyzed later. The robot body 1 is made of thickened cast metal. When an explosion occurs inside the robot body 1, the robot body 1 will not be shattered. Under the impact of the explosion, the pressure plate 92 at the bottom of the explosion-proof window 14 in the robot body 1 moves downward, crushing the glass canister 95 in the explosion-proof structure 9. The carbon dioxide in the glass canister 95 is sprayed out through the exhaust pipe 93 to extinguish the open flame in the robot body 1 and prevent the surrounding environment from exploding. When using this invention for site inspection, no manual inspection is required, reducing the workload of inspection personnel. It also has a strong explosion-proof effect and can be applied to various inspection environments.
