Description

Technical Field

[0001] The utility model relates to the technical field of liquefied petroleum gas, in particular to a monitoring device for storing liquefied petroleum gas. Background Technique

[0002] Liquefied petroleum gas is a colorless volatile liquid obtained by pressurizing and cooling natural gas or petroleum in a refinery. As a clean energy source, liquefied petroleum gas is still used as an important fuel for cooking and heating in residential areas, restaurants, etc. Liquefied petroleum gas is generally contained in steel cylinders, and when the liquefied petroleum gas in the steel cylinder is used up, it can be refilled at the gas supply station.

[0003] For example, the Chinese utility model provides a "safety monitoring device for liquefied gas cylinders" with the patent number: CN201820049890.9. This patent includes a bracket, a bearing plate, a pressure transmitter, an ultrasonic detector, and an electric control box; the number of pressure transmitters is multiple, and each pressure transmitter is arranged vertically and evenly spaced on the mounting surface of the bracket, capable of real-time detecting the medium weight and liquid level of the liquefied gas cylinder, and alarming when the liquid level is excessive or low.

[0004] Although the above document solves the problem that people currently cannot know the amount of liquefied petroleum gas in the storage cylinder until it is used up, and because they cannot judge the amount of liquefied petroleum gas in the cylinder, the phenomenon of gas interruption often occurs during bathing and cooking. However, it still has the disadvantage of being unable to monitor whether the liquefied petroleum gas leaks. The leakage of the liquefied petroleum gas cylinder cannot be discovered in the first time, which is very likely to cause serious safety accidents. Therefore, a monitoring device for storing liquefied petroleum gas is introduced here. Content of the Utility Model

[0023] Secondly, the "one embodiment" or "embodiment" mentioned herein refers to specific features, structures or characteristics that may be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it an independent or selectively mutually exclusive embodiment with other embodiments.

[0024] Embodiment 1:

[0025] Please refer to Figures 1 - 4 As shown, the present utility model provides a monitoring device for liquefied petroleum gas storage, including a base 1.

A spring 10 is fixedly connected to the bottom of the inner cavity of the fixed shell 9. A movable plate 11 is fixedly connected to the top of the spring 10. A connecting plate 12 is fixedly connected to the top of the movable plate 11. A top plate 13 is fixedly connected to the top of the connecting plate 12. A connecting pad 14 is fixedly connected to one side of the bottom of the top plate 13. An upper sealing shell 15 is fixedly connected to the bottom of the connecting pad 14. Liquefied gas leakage detectors 16 are fixedly connected to both sides of the top of the inner cavity of the upper sealing shell 15. An alarm 17 is fixedly connected to the right side of the upper sealing shell 15. A support frame 18 is fixedly connected to the bottom of the base 1. A main chassis 19 is fixedly connected to the left side of the inner cavity of the support frame 18. First, lift the upper sealing shell 15 upward, then place the liquefied petroleum gas cylinder on the bearing seat 7, and then release the upper sealing shell 15. The upper sealing shell 15 returns to its original state under the action of the spring 10 and covers the top of the liquefied petroleum gas cylinder. After the liquefied petroleum gas cylinder is placed on the bearing seat 7, the liquefied petroleum gas cylinder will drive the bearing seat 7 to downwardly press the pressure transmitter 6. The pressure transmitter 6 can detect the weight of the gas cylinder in real time. Since the weight of air cylinders of different specifications is certain, the weight of the medium in the gas cylinder is the weight detected by the pressure transmitter 6 minus the weight of the air cylinder.

[0026] The application of the placement rack 2, through hole 3, installation rod 4, control box 5, pressure transmitter 6, bearing seat 7, upper sealing shell 15, liquefied gas leakage detector 16 and alarm 17 in this technical solution can detect the weight of the liquefied petroleum gas cylinder in real time. The remaining amount of liquefied petroleum gas in the liquefied petroleum gas cylinder can be judged through the change of the weight, and at the same time, whether the liquefied petroleum gas cylinder leaks can be monitored in real time.

[0027] Embodiment 2:

[0028] On the basis of Embodiment 1, the present utility model is as Figures 1 - 3As shown in the figure, it is disclosed that a placement rack 2 is fixedly connected to the top of the base 1. A through opening 3 is provided on the surface of the placement rack 2. An installation rod 4 is fixedly connected to the inner cavity of the through opening 3. A control box 5 is fixedly connected between the installation rods 4. Pressure transmitters 6 are fixedly connected to the four corners of the top of the placement rack 2. A bearing seat 7 is arranged on the top of the pressure transmitter 6. A limiting rod is fixedly connected to the top of the inner cavity of the bearing seat 7. A limiting sleeve is fixedly connected to the inner cavity of the placement rack 2. The surface of the limiting rod is movably connected to the inner cavity of the limiting sleeve. A limiting frame 20 is fixedly connected to the bottom of the top plate 13. A chute is provided at the top of the right side of the vertical plate 8. A slider is movably connected to the inner cavity of the chute. One side of the slider is fixedly connected to the surface of the limiting frame 20. An installation sleeve is fixedly connected to the bottom of the surface of the vertical plate 8. A clamp is fixedly connected to the right side of the installation sleeve.

[0029] By adopting the above technical solution, the main purpose is to improve the stability of the bearing seat 7 during movement, improve the stability of the top plate 13 during up and down movement, and limit and fix the liquefied petroleum gas cylinder. The limiting rod moves in the inner cavity of the limiting sleeve along with the bearing seat 7, which can ensure that the bearing seat 7 does not shake during up and down movement. The limiting frame 20 moves on one side of the vertical plate 8 along with the top plate 13, and the slider on one side of the limiting frame 20 moves in the chute on the surface of the vertical plate 8, thereby improving the stability of the top plate 13 during movement. The clamp wraps and fixes the surface of the liquefied petroleum gas cylinder, which can prevent the liquefied petroleum gas cylinder from shaking easily due to external force during placement.

[0030] Embodiment Three:

[0031] On the basis of Embodiment Two, as shown in the present utility model Figure 1 、 Figure 2 and Figure 4 It is disclosed that limiting grooves are provided on both sides of the inner cavity of the fixed shell 9. Both sides of the movable plate 11 are movably connected to the inner cavity of the limiting grooves. Support pads are fixedly connected to the four corners of the bottom of the support frame 18. Anti-slip patterns are provided on the bottom of the support pads. A lifting plate is fixedly connected to the right side of the upper sealing shell 15. Finger grooves are provided on the surface of the lifting plate.

[0032] By adopting the above technical solution, the main purpose is to improve the movement stability of the movable plate 11, stably support the bottom of the support frame 18, and facilitate the up and down movement of the upper sealing shell 15. Both sides of the movable plate 11 move in the inner cavity of the limiting grooves, which not only has high movement stability but also has a limited movement range. The support pads evenly distributed at the four corners of the bottom of the support frame 18 can stably support the support frame 18, enabling the monitoring device to be stably placed at a specified position. The liquefied petroleum gas user can hold the lifting plate with his hand and conveniently move the upper sealing shell 15 up and down.

[0033] The working principle of the present utility model is as follows: First, lift the upper sealing shell 15 upward, then place the liquefied petroleum gas cylinder on the bearing seat 7, and then release the upper sealing shell 15. The upper sealing shell 15 resumes its original state under the action of the spring 10 and covers the top of the liquefied petroleum gas cylinder. After the liquefied petroleum gas cylinder is placed on the bearing seat 7, the liquefied petroleum gas cylinder will drive the bearing seat 7 to press downward on the pressure transmitter 6. The pressure transmitter 6 can detect the weight of the gas cylinder in real time. Since the weight of air cylinders of different specifications is certain, the weight of the medium in the gas cylinder is obtained by subtracting the weight of the air cylinder detected by the pressure transmitter 6 from the weight of the gas cylinder. During the placement of the liquefied petroleum gas cylinder, if the bottle mouth valve of the liquefied petroleum gas cylinder leaks, the liquefied petroleum gas leak detector 16 can detect the liquefied petroleum gas leak and alarm through the alarm 17.
