Description

Technical Field

[0001] This utility model relates to the field of petrochemical storage equipment technology, specifically to an electrostatic conductive structure for the floating roof of an internal floating roof tank. Background Technology

[0002] The static-dissipating structure of the floating roof of an internal floating roof tank is designed to effectively eliminate the static electricity generated by the floating roof during the storage and dispatching of oil products, ensuring the safe operation of the tank. It is widely used in various types of internal floating roof tanks for storing flammable and explosive oil products.

[0003] In the petrochemical industry, internal floating roof tanks are widely used to store flammable and explosive petroleum products such as gasoline, kerosene, and diesel. However, during the storage and transportation of these products, friction and impact between the floating roof and the oil, as well as the relative movement between the floating roof and the tank wall, can all lead to static electricity generation on the floating roof. Existing static electricity dissipation measures and structures have some shortcomings: 1. Unstable static electricity conduction effect: Some internal floating roof tanks use simple metal chains or wires for static electricity conduction. During long-term use, these connection methods are prone to poor contact due to corrosion, wear and other reasons, which affects the static electricity conduction effect and cannot ensure timely and reliable discharge of static electricity. 2. Poor structural adaptability: Different types and specifications of internal floating roof tanks have different floating roof structures and dimensions. Some existing electrostatic conductive structures have poor versatility and are difficult to adapt to the requirements of various floating roof structures and tank sizes, which limits their application in different scenarios. 3. High maintenance costs: Some complex conductive structures have many parts, and the installation and disassembly process is cumbersome. This increases the workload and cost of maintenance when carrying out tank overhaul or floating roof maintenance. At the same time, due to the complexity of the structure, it is also more difficult to troubleshoot and repair problems when they occur. Utility Model Content

[0015] This utility model provides a technical solution for an electrostatic conductive structure of the floating roof of an internal floating roof storage tank: Please see Figures 1-4 An electrostatic discharge structure for an internal floating roof tank includes a mounting plate 1. Multiple circumferentially arranged mounting grooves 2 are provided on one side of the mounting plate 1. A movable frame 4 is provided on one side of the mounting plate 1. A drive mechanism for moving the movable frame 4 is provided on one side of the mounting plate 1. Multiple circumferentially arranged rotating grooves 8 are provided on the side wall of the movable frame 4. A rotating frame 9 is rotatably connected within the rotating grooves 8. A support mechanism for supporting the rotating frame 9 is provided at one end of the rotating frame 9. Multiple equally spaced mounting tubes 14 are fixedly connected to one side of the rotating frame 9. Contact rods 15 are slidably connected within the mounting tubes 14.

[0016] Furthermore, the drive mechanism includes a motor 5 fixedly connected to one side of the mounting plate 1, and the output shaft of the motor 5 is fixedly connected to a threaded rod 6, which passes through the threaded connection to the movable frame 4.

[0017] Furthermore, a plurality of circumferentially arranged limiting rods 3 are fixedly connected to one side of the mounting frame 1, and the limiting rods 3 pass through the sliding connection movable frame 4.

[0018] Furthermore, the support mechanism includes a connecting rod 10 fixedly connected to one end of the rotating frame 9, a mounting ball 11 fixedly connected to one end of the connecting rod 10, a ball seat 12 sleeved on the side wall of the mounting ball 11, and a sliding frame 13 fixedly connected to the side wall of the ball seat 12.

[0019] Furthermore, a baffle plate 16 is fixedly connected to one end of the contact rod 15 inside the mounting tube 14. The baffle plate 16 is slidably connected inside the mounting tube 14. A connecting line 18 is provided at one end of the contact rod 15, and a wire 7 is provided on one side of the sliding frame 13.

[0020] Furthermore, a connecting spring 17 is sleeved on the side wall of the contact rod 15, and the two ends of the connecting spring 17 are respectively fixedly connected to the mounting tube and the barrier plate 16.

[0021] In practical use, the working principle of this utility model is as follows: First, the mounting plate 1 is installed on the floating roof using bolts through multiple mounting slots 2 on the mounting plate 1. Then, a corresponding number of rotating frames 9 are selected based on the number of support rods on the floating roof to adapt to its movement. Next, the sliding frame 13 is slidably fitted onto the support rods of the floating roof. The ball seat 12 and mounting ball 11 on the sliding frame 9 provide adjustable sliding support. When it is necessary to conduct static electricity on the floating roof, the motor 5 on the mounting plate 1 drives the threaded rod 6 to rotate. The threaded rod 6 is threadedly connected to the moving frame 4. Under the sliding limit of multiple limit rods 3, the moving frame 4 moves up and down. During the downward movement of the moving frame 4, it drives the rotating frame 9 to rotate within the rotating slot 8. The rotating frame 9 moves under the sliding support of the sliding frame 13. At this time, the connecting rod 10 and the mounting ball 11 can provide support for one end of the rotating frame 9 and support for the rotation direction. During the movement of the rotating frame 9, the contact rod 15 slides in the mounting tube 14 after contacting the floating plate support rod. At this time, the baffle plate 16 slides in the mounting tube 14, which can support and limit the contact rod 15 while blocking the transmission of static electricity. At this time, the static electricity is transmitted to the connecting line 18 through the contact rod 15 at the point where it contacts the floating plate support rod. At the same time, the wire 7 on the sliding frame 13 can be used as the static electricity transmission line, which can complete the multi-point transmission of static electricity on the floating plate and the support rod, thereby improving the conduction efficiency of static electricity.
