Description

Technical Field

[0001] This utility model mainly relates to the field of internal floating platforms, and specifically to an internal floating platform monitoring device. Background Technology

[0002] Internal floating roofs are key safety and environmental protection devices widely used in large atmospheric pressure storage tanks (such as crude oil, refined oil, and chemical liquid storage tanks) in industries such as petroleum, chemical, and pharmaceutical. By closely fitting the liquid surface, they greatly reduce the contact area between the stored medium (especially volatile liquids) and air, thereby significantly reducing material evaporation losses caused by respiration, saving resources and reducing economic losses. They also effectively reduce the concentration of flammable gases in the gas phase space of the storage tank, reducing the risk of reaching the explosion limit, and play a vital role in preventing major safety accidents such as fires and explosions. Internal floating roofs may fail due to various reasons during long-term operation, mainly including: Sinking plate: The floating plate is completely or partially submerged below the liquid surface, losing all sealing and buoyancy functions.

[0003] Chuck: The floating roof is stuck by tank wall attachments or other obstacles during the rising or falling process, and cannot move freely with the liquid level.

[0004] Tilting / Slanting: The floating roof tilts, resulting in uneven buoyancy distribution. Some areas may sink to the liquid surface or experience abnormal friction with the tank wall.

[0005] During the operation of specific embodiments, the inventors discovered the following defects: Currently, the most common monitoring method remains periodic manual inspections. Operators must enter the tank (a confined space operation, high risk) or conduct visual inspections and measurements through manholes on the tank top. This method is inefficient, lacks real-time performance, is costly, and cannot detect sudden malfunctions in a timely manner. The floating roof may have failed undetected during the inspection interval.

[0006] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0007] 1. The technical problem to be solved by the utility model: This invention provides an internal floating disk monitoring device to solve the technical problems existing in the background art.

[0008] 2. Technical Solution: To achieve the above objectives, the technical solution provided by this utility model is as follows: an internal floating roof monitoring device, comprising an atmospheric pressure tank structure, an installation structure being provided on the top of the atmospheric pressure tank structure, and a monitoring structure being provided inside the installation structure; A monitoring structure includes an externally threaded shaft, a monitor is provided at the bottom of the externally threaded shaft, and a top plate is provided at the top of the externally threaded shaft.

[0009] Furthermore, the atmospheric pressure storage tank structure includes a connecting pipe at the top of the atmospheric pressure storage tank body, a connecting flange at the top of the connecting pipe, and an installation hole inside the connecting flange.

[0010] Furthermore, the mounting structure includes a mounting tube, the outer wall of which is provided with a fixing flange, the fixing flange being fitted with a connecting flange, and a fixing bolt being provided between the fixing flange and the mounting hole.

[0011] Furthermore, a side plate is provided at the top of the mounting tube, an internally threaded tube is provided on the inner side of the side plate, and glass is provided at the bottom of the inner wall of the mounting tube.

[0012] Furthermore, the external threaded shaft is disposed inside the internal threaded tube, and the external threaded shaft is threadedly connected to the internal threaded tube.

[0013] 3. Beneficial effects: Compared with the prior art, the technical solution provided by this utility model has the following advantages: This invention involves pre-installing an installation structure on the top of the atmospheric pressure storage tank body, and then connecting the monitoring structure to the atmospheric pressure storage tank body through the installation structure. The monitor installed inside the monitoring structure can monitor the internal floating plate inside the atmospheric pressure storage tank body in real time, preventing problems such as displacement of the internal floating plate. Furthermore, since the monitoring structure needs to be connected by cable, but there cannot be any cables inside the atmospheric pressure storage tank body, the glass installed can isolate the two and prevent short circuits in the cables from causing explosions or leaks of the liquid stored inside the atmospheric pressure storage tank body.
