Technical Field

[0001] The utility model relates to the technical field of storage tank monitoring, in particular to a floating roof monitoring device. Background Art

[0002] Petrochemical storage tanks are used to store petrochemical raw material liquids; during the storage process of petrochemical raw materials, volatilization is likely to occur; in order to monitor the liquid level in the petrochemical storage tank, a monitoring radar is mostly set above the storage tank.

However, this method will cause the problem of circuit entanglement, and thus requires shutdown for maintenance.

[0031] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0032] As Figures 1 to 5 shown, at least one embodiment provides a floating disc monitoring device, including: a cylinder 1 and a monitoring mechanism 2 disposed inside the cylinder 1; the monitoring mechanism 2 includes a monitoring motor 21 and a monitoring radar 22, and the monitoring motor 21 and the monitoring radar 22 are connected through a conductive slip ring 29; and a driving motor 23, the driving motor 23 is adapted to drive the monitoring radar 22 to rotate so that the monitoring radar 22 rotates to obtain floating disc information.

[0033] In some embodiments, by providing the conductive slip ring 29, the monitoring motor 21 of the monitoring mechanism 2 is connected to the monitoring radar 22, and the fixed end of the conductive slip ring 29 is connected to the monitoring motor 21, and the rotating end is connected to the monitoring radar 22, thereby avoiding the problem of wire entanglement caused by the traditional monitoring motor 21 and the monitoring radar 22 rotating together.

[0034] Specifically, the cylinder body 1 includes an upper cylinder and a lower cylinder. The support ring 24 is arranged inside the lower cylinder. And as an optional implementation manner, the support ring 24 is bolted to the lower cylinder. The support ring 24 is used to carry the monitoring motor 21 and the driving motor 23. Among them, a support cover 25 is erected above the support ring 24. By providing the support cover 25, on the one hand, it is convenient to fix the bodies of the two motors, and on the other hand, it also prevents the oil and gas entering from below the cylinder body 1 from diffusing into the motors and causing damage to the motors.

[0035] In some embodiments, the monitoring motor 21 is connected to the support cover 25, and the support cover 25 is bolted to the support ring 24. And, an extension hole for the conductive slip ring 29 to extend out is opened at the top of the support cover 25. The fixed end of the conductive slip ring 29 is connected to the monitoring motor 21, and its rotating end extends into the support cover 25 and is connected to a rotating gear 211 arranged between the support cover 25 and the support ring 24, so as to realize the support for the rotating end of the conductive slip ring 29.

[0036] In some embodiments, the rotating gear 211 meshes with a driving gear 231 sleeved on the rotating shaft of the driving motor 23, and thus rotates under the driving action of the driving motor 23. At the same time, a bearing 28 is arranged at the bottom of the rotating gear 211, and a connecting frame 26 is arranged at the bottom of the bearing 28. The monitoring radar 22 is arranged on the connecting frame 26. Thus, when the rotating gear 211 rotates, it drives the monitoring radar 22 to rotate circumferentially, realizing 360° detection of the floating disc.

[0037] In some embodiments, an encoder 27 is arranged on the housing of the monitoring motor 21, and the encoder 27 is connected to the motor shaft of the monitoring motor 21 to obtain the number of rotation turns of the monitoring motor 21.

[0038] In summary, the floating disc monitoring device of the present invention connects the monitoring motor 21 of the monitoring mechanism 2 and the monitoring radar 22 through the provided conductive slip ring 29. And, the fixed end of the conductive slip ring 29 is connected to the monitoring motor 21, and the rotating end is connected to the monitoring radar 22, thus avoiding the problem of wire entanglement caused by the traditional monitoring motor 21 and the monitoring radar 22 rotating together.
