Problems solved by technology

[0005] The first detection method is used to detect the internal capacity of the gas cylinder, which is not affected by the placement state of the gas cylinder. However, if the gas in the gas cylinder has a physical state change, the gas pressure in the gas cylinder will rise and fall rapidly due to the physical state change. , which in turn affects the staff's judgment on the capacity of the gas cylinder, resulting in waste and wrong discharge
For example: when the sulfur hexafluoride hydraulic cylinder is used, the sulfur hexafluoride liquid will absorb heat during the gasification process, resulting in the solidification of the remaining sulfur hexafluoride liquid, and then the air pressure in the cylinder measured by the pressure gauge of the cylinder will drop rapidly , it is easy to cause the staff to misjudge the remaining amount of sulfur hexafluoride in the gas cylinder, thus affecting the use
[0006] like figure 1 , figure 2 As shown, the second detection method is used to detect the internal capacity of the gas cylinder. The gas cylinder needs to be placed vertically on the shelf, and the gas cylinder cannot be tilted. If the gas cylinder is slightly tilted, the weight of the gas cylinder cannot be accurately measured. And then affect the staff to judge the cylinder capacity

Embodiment 1

[0029] like image 3 , 4 As shown, a gas cylinder weight detection device provided in this embodiment includes a placing rack 1, a control cabinet 2 and several sensors;

[0030] Placement rack 1, the gas cylinder 100 is placed on the placement rack 1, and the sensor is installed on the placement rack 1; for placing the gas cylinder 100, the gas cylinder 100 is placed vertically on the placement rack 1 and is inflated and detected Keep the gas cylinder 100 fixed during the process;

[0031] The sensors are respectively arranged below the gas cylinder 100 and on both sides of the gas cylinder 100; they are used to measure the pressure generated by the weight of the gas cylinder 100 in the vertical and horizontal directions of the placing rack 1;

[0032] The control cabinet 2 includes a display screen 21, a controller and a gyroscope; the gyroscope detects the inclination angle of the gas cylinder 100; the controller is electrically connected with the display screen 21, the g...

Embodiment 2

[0047] As a preferred embodiment solution, the placement rack 1 includes a frame 11, a base 12 and at least one hoop 13; the frame 11 is a rectangular frame 11 formed by splicing several vertically and horizontally arranged links; the frame 11 Installed on the base 12 , the hoop 13 is installed on the frame 11 ; the sensors are respectively installed on the base 12 and the hoop 13 ; the gas cylinder 100 passes through the hoop 13 and is vertically arranged on the base 12 .

[0048] The hoop 13 includes a first half-ring 131 and a second half-ring 132, and both ends of the first half-ring 131 and the second half-ring 132 are respectively connected to form a circular ring by bolts; the first half-ring 131 and the second half-ring 131 Both ends of the second half ring 132 are respectively connected to the frame 11 through a first connecting rod and a second connecting rod; the dynamometer 31 is respectively installed on the first connecting rod and the second connecting rod.

Embodiment 3

[0052] As a preferred embodiment, the placement rack 1 further includes a reinforcing support rod 14 arranged in a triangle shape with the frame 11 and the base 12; the reinforcing support rod 14 and the hoop 13 are located on both sides of the frame 11, respectively, The utility model is used to support the placing rack 1, and avoid that the base 12 of the placing rack 1 is narrow and the frame 11 for fixing the gas cylinder 100 is high, which will cause the center of gravity to move upward, resulting in the unstable placement of the placing rack 1.

[0053] Preferably, the frame 11 is not in the centerline position of the base 12, and the width of the side of the base 12 that prevents the gas cylinder 100 from being larger than the width of the reinforcing support rod 14 is installed, so that the center of gravity of the placing rack 1 after the gas cylinder 100 is installed is not too far. The side where the gas cylinder 100 is installed is offset, causing the placement rack...

Abstract

The invention relates to a gas cylinder weight detection device, which relates to the technical field of gas cylinder inflation detection, and comprises a placement frame, a control cabinet and several sensors; the gas cylinder in the placement frame is placed on the placement frame, and the sensors are installed on the placement frame; The sensors are respectively arranged under the gas cylinder and on both sides of the gas cylinder; the control cabinet includes a display screen, a controller and a gyroscope; the controller is electrically connected with the display screen, the gyroscope and each sensor. The invention also discloses a method for detecting the weight of the gas cylinder. The gas cylinder is vertically placed on the rack, and the force received by the weight of the gas cylinder and the inclination angle of the gas cylinder on the rack in the horizontal and vertical directions are measured to calculate the weight of the gas cylinder. The weight of the cylinder. In the gas cylinder weight detection device and its detection method disclosed in the present invention, sensors for testing the pressure of the gas cylinder against the rack are arranged on the bottom and both sides of the gas cylinder, and a gyroscope is arranged to measure the inclination angle of the gas cylinder, so that the gas cylinder The weight of the gas cylinder can still be accurately measured in the tilted state.

Description

technical field [0001] The invention relates to the technical field of gas cylinder weight detection, in particular to a gas cylinder weight detection device and a detection method thereof. Background technique [0002] Gas cylinder refers to a mobile pressure vessel containing permanent gas, liquefied gas or dissolved gas with a nominal working pressure of 1.0 to 30 MPa and a nominal volume of 0.4 to 1000 L that can be used repeatedly under normal conditions (-40 to 60 °C). . During the use of gas cylinders, the following two methods are usually used to detect the capacity of gas cylinders: [0003] (1) Measure the pressure in the gas cylinder according to the pressure gauge at the mouth of the gas cylinder, and then judge the content of the gas cylinder; [0004] (2) Weigh the gas cylinder according to the weighing scale placed at the bottom of the gas cylinder, and then judge the capacity of the gas cylinder. [0005] The content of the gas cylinder is detected by the ...
