Description

Technical Field

[0001] The utility model relates to the technical field of pressure vessel volume measurement, in particular to a vertical buoyancy method volume measurement device. Background Art

[0002] The volume of pressure vessels is one of the most important technical indicators, and its measurement method is often the water-tight method. The pressure vessel is most commonly a gas cylinder. First, the weight of the empty cylinder is measured, then the cylinder is filled with water, the weight of the water-filled cylinder is measured, and the volume of the cylinder is calculated through conversion. However, this method is inefficient. Taking a 40L gas cylinder as an example, it takes 4-5 minutes to fill it with water and 6-7 minutes to empty it. In other words, it takes more than 10 minutes to measure the volume of each gas cylinder using the water-tight method. The entire measurement process is long and inefficient, consuming a lot of manpower and time. In addition, since the gas cylinder is made of steel, it needs to be dried after using the water-tight method to prevent corrosion inside the cylinder. Summary of the Invention

[0003] Based on this, the utility model provides a vertical buoyancy volume measuring device, which measures the volume of the gas cylinder by immersing the gas cylinder vertically in water, thereby not only improving efficiency but also preventing corrosion inside the gas cylinder.

[0025] Figure 1 This is a schematic diagram of the structure of the vertical buoyancy method volume measurement device. DETAILED DESCRIPTION

[0026] The utility model discloses a vertical buoyancy method volume measurement device. Figure 1 , which includes a water tank 1, a weighing mechanism 2, a hanging chain 3, a guide column 4, a hanging basket mechanism 5, a lifting mechanism 6 and a gas cylinder mechanism 7. The water tank 1 is an open structure, and a medium 11 is filled inside it, and the medium 11 is generally water. The bottom of the water tank 1 is fixedly connected to one end of the guide column 4, wherein the other end of the guide column 4 is higher than the water tank 1. The weighing mechanism 2 includes an electronic scale 21 and an electronic scale bracket 22. The electronic scale bracket 22 is a counterweight setting to prevent the electronic scale 21 from floating up. The electronic scale bracket 22 is mounted on the guide column 4 to facilitate the weighing mechanism 2 to move up and down along the guide column 4, that is, the weighing mechanism 2 reciprocates up and down along the vertical wall of the water tank 1, and the position of the weighing mechanism 2 can be quickly stabilized. The electronic scale bracket 22 is connected to the hanging basket mechanism 5 and moves up and down through the lifting mechanism 6, thereby driving the movement of the weighing mechanism 2, making it convenient to hook the hanging chain 3 with the gas cylinder mechanism 7 at the top of the water tank 1. The hanging basket mechanism 5 includes a hanging basket rod 51 and a hanging basket crossbeam 52. One end of the hanging basket rod 51 is connected to both ends of the electronic scale bracket 22, and the other end of the hanging basket rod 51 is connected to the hanging basket crossbeam 52. The lifting mechanism 6 includes a lifting pulley 51 and a lifting rope 62. The lifting rope 62 is connected to the hanging basket crossbeam 52. The gas cylinder mechanism 7 is arranged inside the hanging basket mechanism 5. The gas cylinder mechanism 7 includes a gas cylinder base 71 and a gas cylinder blocking mechanism 72. The gas cylinder base 71 is arranged at the bottom of the gas cylinder. The gas cylinder blocking mechanism 72 is connected to the hanging basket crossbeam 52. The gas cylinder base 71 is connected to the electronic scale 22 via the suspension chain 3, thereby calculating the buoyancy value of the gas cylinder and obtaining the gas cylinder volume.

[0027] The electronic scale 22 is a waterproof electronic scale 22 .

[0028] The present invention uses an upright gas cylinder immersed in water, eliminating the need for external pressure. The electronic scale readings on the gas cylinders can quickly stabilize and become more accurate. Compared to horizontal pressure measurement, the upright method only requires one electronic scale, while the horizontal method requires multiple pressure sensors for measurement, resulting in larger errors. Furthermore, the horizontal buoyancy method requires a large water tank for volume measurement, while the upright method requires a small area, enabling large-scale simultaneous testing. Therefore, the vertical buoyancy method volume measurement device disclosed in the present invention is more in line with actual factory production.

[0029] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
