Description

Technical Field

[0001] This utility model relates to the field of storage tank technology, and in particular to a lifting and scanning type automatic density meter for storage tanks. Background Technology

[0002] The scanning density automatic meter is an automated device used to measure the density, level and mass of liquids in storage tanks. Its core principle combines Archimedes' law of buoyancy, static pressure measurement and three-dimensional laser scanning technology, and is suitable for accurate measurement in industries such as petroleum and chemical.

[0003] Storage tanks are used to store refined chemical substances such as acids, alkalis, alcohols, gases, and liquids. Equipped with automatic scanning density meters, they can accurately and safely perform multi-dimensional scanning and measurement of the fluids inside the tank. However, existing automatic scanning density meters still have the following drawbacks that need to be addressed: When manually holding the instrument to measure the fluid in the tank, it is necessary to place the instrument as close to the fluid as possible to reduce the influence of the surrounding environment on the measurement results. However, the fluid levels inside the tank vary, and the density of fluids at lower levels may be affected by the tank environment, leading to inaccurate measurement results. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a lifting and scanning automatic density meter for storage tanks.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A lifting scanning automatic density meter for storage tanks includes a main body of the scanning automatic density meter, which contains multiple sets of measuring mechanisms. A retaining ring is fixedly installed at the top of the main body, and a fixed cover is provided at the top of the main body. A docking groove is provided at the bottom of the fixed cover. A pressure plate is fixedly installed in the middle of the outer wall of the top of the fixed cover, and a hand-held component is fixedly installed in the middle of the top of the pressure plate. A lifting control button and a start switch button are provided on one side of the top of the fixed cover. A control box is fixedly installed at the top of the inside of the fixed cover. Rotating rods are rotatably installed at the lower ends of both ends inside the fixed cover, and a pull rope is wound around both sides of the circumference of each rotating rod. Two drive gears are rotatably installed at the lower end of the inner wall of one side of the fixed cover, and the two drive gears are circumferentially meshed. A drive motor is fixedly installed at the input end of one of the drive gears. A transmission gear is fixedly sleeved on one side of each of the two rotating rods, and the circumference of the transmission gear meshes with the circumference of the drive gear.

[0006] Preferably, a lock frame is fixedly installed on the upper end of the outer wall of one end of the main body of the scanning density automatic meter, and the top of the lock frame is provided with an insertion port. Guide rings are provided on both sides of the lock frame. An unlocking frame is slidably inserted between each end of the lock frame and the guide ring on the same side, and a retraction spring is sleeved on the circumferential section of the unlocking frame.

[0007] Preferably, the end of the handheld component is L-shaped, and a movable rod is slidably installed inside the end of the handheld component. A cover plate is fixedly installed at the end of the movable rod. A plug is fixedly connected to the bottom of the cover plate, and storage openings are provided on both sides of the lower end of the plug. A clip is slidably installed inside the two storage openings, and multiple spring posts are fixedly installed on the outer walls of the opposite ends of the two clips.

[0008] Preferably, the top of the card ring and the four sides of the foreign currency are magnetically engaged with the docking groove.

[0009] Preferably, the four ends of the pull ropes are fixedly installed on the outer wall of the top of the scanning density automatic meter body, and the four pull ropes are located inside the retaining ring.

[0010] Preferably, guide sleeves are fixedly installed on both sides of the lower end of the inner wall at both ends of the fixed cover, and each pull rope slides through the inside of the guide sleeve.

[0011] Preferably, the main body of the scanning automatic density meter has the same length and width as the outer side of the fixed cover.

[0012] The beneficial effects of this utility model are as follows: This utility model proposes a lifting and scanning automatic density meter for storage tanks. In normal operation, the bottom of the fixed cover is magnetically engaged with the top of the main body of the scanning automatic density meter. The plug is inserted into the locking frame to limit the fixed cover and the main body of the scanning automatic density meter. The operator can use the handheld device to measure the fluid inside the storage tank. When the fluid level in the storage tank is low, pressing the two unlocking brackets causes the plug to disengage from the locking frame. Then, the operator manually assists in separating the fixed cover from the main body of the scanning automatic density meter. Next, pressing the lifting control button activates the drive motor. One of the drive gears drives the other drive gear to rotate in the opposite direction, which in turn drives the two transmission gears and the rotating rod to rotate in opposite directions. As the rotating rod rotates, the pull rope lengthens, and the main body of the scanning automatic density meter is lowered closer to the surface of the fluid in the storage tank for more accurate scanning and measurement.

[0013] This utility model proposes a lifting scanning automatic density meter for storage tanks. The ends of four pull ropes are fixedly installed on the outer wall of the top of the main body of the scanning automatic density meter, and the four pull ropes are located inside the retaining ring. This makes the top of the main body of the scanning automatic density meter uniformly stressed and moves horizontally and stably upward or downward. Each pull rope slides through the inside of the guide sleeve, so that the guide point of the pull rope remains unchanged during the winding or unwinding process, further enhancing the stability of the longitudinal movement of the main body of the scanning automatic density meter.
