Description

Technical Field

[0001] This utility model relates to the field of gas station monitoring technology, specifically a monitoring and alarm device. Background Technology

[0002] Gas stations are facilities that provide fuel for cars and services for other vehicles. Drivers can refuel their vehicles with gasoline or diesel and replenish lubricating oil at gas stations. Since the fuel in gas stations is flammable, explosive, and volatile, monitoring and alarm devices are needed to monitor the station in real time so that staff can promptly detect and deal with leaks.

[0003] A gas station leak monitoring and alarm device, with announcement number CN222145598U, is based on an installation mechanism, which is centered on an installation plate. An installation groove is located at the center of the front side of the installation plate, and a monitoring alarm is installed inside the groove. A protective cover is installed on the front side of the installation plate and is fastened to the surface of the monitoring alarm. Installation holes are located at the inner edge of the installation plate. Through a connecting plate and sliding rod structure, a fixing protrusion can be moved downwards, thereby fastening the installation plate onto the fixing protrusion with the cooperation of the installation hole. Then, with the cooperation of a spring, the fixing protrusion is reset, fastening it to the top side of the installation hole, thus fixing the position of the installation plate. This structure is easy to assemble and disassemble, improving the efficiency of subsequent disassembly and maintenance.

[0004] The gas station leak monitoring and alarm device described above still has a problem: when using this monitoring and alarm device, its rectangular plate can only be installed in a fixed position, and the position cannot be changed after installation, which limits the monitoring range of the monitoring and alarm device, thus making it impossible to detect leaks in other locations in a timely manner. Therefore, a monitoring and alarm device is proposed. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the rectangular plates of commercially available monitoring and alarm devices can only be installed in fixed positions, and the positions cannot be changed after installation. This limits the monitoring range of the monitoring and alarm devices, making it impossible to detect leaks in other locations in a timely manner. This utility model proposes a monitoring and alarm device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The monitoring and alarm device of this utility model includes a fixing plate; a fixing mechanism is provided at the four corners of the side of the fixing plate, a connecting mechanism is provided on the inner side of the fixing plate, a protective mechanism is provided on the side of the connecting mechanism, and a cylinder is fixed at the four corners of the side of the fixing plate.

[0007] Preferably, the fixing mechanism includes a cylinder, with limit rods symmetrically fixed inside the cylinder, a piston slidably mounted inside the cylinder and slidably connected to the limit rods, a rubber seat fixed to the side of the piston, a lead screw rotatably inserted inside the cylinder, a turntable fixed to one end of the lead screw, suction cups fixed at the four corners of the side of the fixing plate, one end of the suction cup passing through the fixing plate and communicating with the inside of the cylinder, the lead screw rotatably connected to the piston, the lead screw rotatably connected to the rubber seat, and a connecting seat fixed to the side of the fixing plate. Through the cooperation of the suction cups and the cylinder, the fixing plate can be adsorbed and fixed on any smooth surface, allowing the monitoring alarm to be installed in any position as needed, making the device more flexible and convenient to use, and enabling timely detection of fuel leaks.

[0008] Preferably, the connecting mechanism includes a connecting seat, with a limiting groove on the inner side of the connecting seat. A mounting seat is slidably installed on the inner side of the limiting groove via a slider. A positioning groove is symmetrically provided on the top inner side of the fixing plate. A plug rod is symmetrically slidably installed on the top inner side of the mounting seat. The plug rod is fastened to the inner side of the positioning groove. A limiting cap is fixed to one end of the plug rod. A spring is fixedly connected between the limiting cap and the mounting seat. The monitoring alarm body is fixedly installed on the inner side of the mounting seat. A shaft is fixed at the bottom inner side of the mounting seat. The plug rod and the spring are used for fixation. The mechanism allows for quick assembly and disassembly and operation testing, facilitating subsequent maintenance and replacement by operators.

[0009] Preferably, the protection mechanism includes a shaft with a rotating seat rotatably mounted on it. A grille is fixed to one end of the rotating seat. A fixing groove is symmetrically opened at the top inner side of the mounting seat. The grille is fastened to one side of the monitoring alarm body. Elastic blocks are symmetrically fixed to the top side of the grille and fastened to the inside of the fixing groove. Through the structure of the grille, the monitoring alarm can be prevented from being bumped or knocked, while not affecting the monitoring alarm's ability to detect whether a leak has occurred, thus making it more convenient to use.

[0010] The advantages of this utility model are:

[0011] 1. This utility model, through the structural design of a monitoring and alarm device, uses a fixing mechanism to attach a fixing plate to the installation position, ensuring a tight fit between the suction cup and the smooth surface. The rotating disc then drives the piston to slide towards the end of the cylinder, thereby extracting air from the inside of the suction cup. This allows the fixing plate to be adhered and fixed in the desired installation position with the assistance of the suction cup. Simultaneously, the rubber seat ensures a seal at the connection between the piston and the lead screw, preventing the fixing plate from detaching. This allows the device to be installed in any position and promptly detect fuel leaks, solving the problem of limited monitoring range and inability to detect fuel leaks in existing alarm devices.

[0012] 2. This utility model, through the structural design of a monitoring and alarm device, by setting a connecting mechanism, allows the mounting base to be installed into the limiting groove inside the connecting base with the cooperation of the slider. At this time, the spring pulls the plug rod to be fastened inside the positioning groove. The monitoring and alarm body can detect whether there is a fuel leak. When disassembly and maintenance are required, the limiting cap can be pulled to pull out the plug rod, releasing the fixing of the mounting base, thereby allowing the mounting base to be pulled out from the inside of the connecting base for maintenance and replacement.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 scope of protection of the present utility model.

[0021] Please see Figures 1-4As shown, a monitoring and alarm device includes a fixing plate 1; fixing mechanisms are provided at the four corners of the side of the fixing plate 1, a connecting mechanism is provided on the inner side of the fixing plate 1, a protective mechanism is provided on the side of the connecting mechanism, and a cylinder 2 is fixed at the four corners of the side of the fixing plate 1.

[0022] Please see Figure 2 As shown, the fixing mechanism includes a cylinder 2, with limit rods 7 symmetrically fixed inside the cylinder 2. A piston 3 is slidably mounted inside the cylinder 2, and the piston 3 is slidably connected to the limit rods 7. A rubber seat 4 is fixed to the side of the piston 3. A lead screw 5 is rotatably inserted inside the cylinder 2, with a turntable 6 fixed to one end of the lead screw 5. Suction cups 8 are fixed at the four corners of the side of the fixing plate 1, with one end of the suction cup 8 passing through the fixing plate 1 and communicating with the inside of the cylinder 2. The lead screw 5 is rotatably connected to the piston 3 and the rubber seat 4. A connecting seat 9 is fixed to the side of the fixing plate 1. During operation, when the monitoring range of the existing monitoring and alarm device is limited... When the system cannot detect leaks in a timely manner, the fixing mechanism can be used to select a suitable smooth surface and attach the fixing plate 1 to the installation position, ensuring that the suction cup 8 is tightly attached to the smooth surface. At this time, the turntable 6 can be rotated, causing the lead screw 5 to rotate. With the cooperation of the limiting rod 7, the piston 3 is driven to slide inside the cylinder 2 towards the end close to the turntable 6, thereby extracting the air inside the suction cup 8. With the cooperation of the suction cup 8, the fixing plate 1 is adsorbed and fixed in the required installation position. At the same time, with the cooperation of the rubber seat 4, the connection between the piston 3 and the lead screw 5 can be sealed to prevent the fixing plate 1 from falling off. This allows the device to be installed in any position and detect fuel leaks in a timely manner.

[0023] Please see Figure 3 As shown, the connecting mechanism includes a connecting seat 9, with a limiting groove 10 on the inner side of the connecting seat 9. A mounting seat 12 is slidably mounted on the inner side of the limiting groove 10 via a slider 11. A positioning groove 13 is symmetrically provided on the top inner side of the fixing plate 1. A plug rod 14 is symmetrically slidably mounted on the top inner inner side of the mounting seat 12. The plug rod 14 is fastened to the inner side of the positioning groove 13. A limiting cap 15 is fixed to one end of the plug rod 14. A spring 16 is fixedly connected between the limiting cap 15 and the mounting seat 12. A monitoring alarm body 121 is fixedly mounted on the inner side of the mounting seat 12. A shaft 17 is fixed to the bottom side. During operation, when the existing monitoring and alarm device is difficult to disassemble and assemble, the mounting base 12 can be installed into the limiting groove 10 inside the connecting base 9 through the structure of the connecting mechanism and with the cooperation of the slider 11. At this time, the spring 16 pulls the insert rod 14 to be fastened inside the positioning groove 13. The monitoring and alarm body 121 inside the mounting base 12 can detect whether there is a fuel leak. When disassembly and maintenance are required, the limiting cap 15 can be pulled to pull out the insert rod 14, release the fixing of the mounting base 12, and thus pull the mounting base 12 out from the inside of the connecting base 9 for maintenance and replacement.

[0024] Please see Figure 4 As shown, the protection mechanism includes a shaft 17, on which a rotating seat 18 is rotatably mounted. A grille 19 is fixed to one end of the rotating seat 18. A fixing groove 21 is symmetrically opened on the top inner side of the mounting base 12. The grille 19 is fastened to one side of the monitoring alarm body 121. Elastic blocks 20 are symmetrically fixed to the top side of the grille 19 and are fastened to the inside of the fixing groove 21. During operation, if the device is easily damaged by impact, the structure of the protection mechanism can push the grille 19 to rotate around the shaft 17, thereby fastening the grille 19 to one side of the monitoring alarm body 121. At this time, with the cooperation of the elastic blocks 20, one end of the grille 19 is fastened and fixed to the inside of the fixing groove 21, thus protecting the monitoring alarm body 121 without affecting the accuracy of its detection results.

[0025] Please see Figure 5 As shown, a handle 22 is fixed on the top side of the mounting base 12. During operation, when the monitoring and alarm device inside the fixing plate 1 is inconvenient to remove, the structure of the handle 22 can be used to release the fixing between the mounting base 12 and the fixing plate 1. Then, the handle 22 can be pulled to pull the mounting base 12 out from the inside of the connecting seat 9, which facilitates disassembly and improves the efficiency of subsequent maintenance and replacement.

[0026] Working Principle: Gas stations are facilities that provide fuel for automobiles and services for other vehicles. Drivers can refuel their vehicles with gasoline or diesel and replenish lubricating oil at gas stations. Since the fuel in gas stations is flammable, explosive, and volatile, a monitoring and alarm device is needed to monitor the station in real time, alerting staff to promptly detect and address leaks. Existing monitoring and alarm devices have rectangular plates that can only be installed in a fixed position, and this position cannot be changed after installation, limiting the monitoring range and preventing timely detection of leaks in other locations. To solve this problem, a fixing and connecting mechanism is set up. A suitable smooth surface is selected, and the fixing plate 1 is attached to the installation position, ensuring the suction cup 8 is tightly fitted to the smooth surface. The turntable 6 can then be rotated, causing the lead screw 5 to rotate. With the cooperation of the limiting rod 7, the piston 3 slides inside the cylinder 2 towards the end close to the turntable 6, thereby extracting air from the inside of the suction cup 8. This allows the fixing plate 1 to be adhered and fixed in the required installation position with the help of the suction cup 8. Simultaneously, the rubber seat 4... When closed, the connection between piston 3 and lead screw 5 is sealed, preventing the fixing plate 1 from falling off and allowing the device to be installed in any position. Then, with the cooperation of slider 11, mounting base 12 can be installed into the limiting groove 10 inside connecting base 9. At this time, spring 16 pulls insertion rod 14 to fasten into the positioning groove 13. At this time, the grille 19 can be pushed to rotate around shaft 17, thereby fastening the grille 19 to one side of monitoring alarm body 121. At this time, with the cooperation of elastic locking block 20, one end of grille 19 is fastened and fixed inside fixing groove 21. One end of the grille 19 is fastened to one side of the limit cap 15 to prevent the limit cap 15 from falling off under force. After installation, the monitoring alarm body 121 inside the mounting base 12 can detect whether there is a fuel leak. When disassembly and maintenance are required, the grille 19 can be pushed to pull the elastic block 20 out of the fixing groove 21, and the limit cap 15 can be pulled out to remove the rod 14, thereby releasing the fixing of the mounting base 12 and pulling the mounting base 12 out from the inside of the connecting base 9 for maintenance and replacement. This solves the problem that the monitoring range of the existing alarm device is limited and cannot detect fuel leaks in time.
