Description

Technical Field

[0001] This utility model relates to the technical field of gas pressure reducing equipment, specifically a portable gas pressure reducing device for use in small generators. Background Technology

[0002] In the power supply system, power outages and shortages occur occasionally. Traditional solutions rely on gasoline and diesel generators, but these have significant limitations: these generators are bulky and heavy, difficult to transport and deploy, and require continuous fuel consumption, resulting in high operating costs and hindering widespread adoption in residential and other scenarios. In regions with abundant natural gas resources but insufficient power supply, there is a lack of efficient, portable power generation devices that can utilize natural gas to meet daily household electricity needs. Therefore, developing a gas pressure-reducing supply device that is compatible with small generators, easily portable, and relies on natural gas resources has become an urgent need to solve regional power shortages and expand access to electricity.

[0003] Currently, when people experience power outages or shortages, they need to use gasoline or diesel generators to generate electricity. However, these products are bulky, heavy, and costly to operate, making them difficult to widely promote in the market. Utility Model Content

[0004] The purpose of this invention is to provide a portable gas pressure reducing device for use in small generators, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A portable gas pressure reducing device for use in small generators includes a gas cylinder, a mobile carrier, and a pipeline control assembly. The pipeline control assembly includes a primary pressure reducer and a secondary pressure reducer fixedly mounted on the mobile carrier. A cylinder valve is connected to the gas cylinder, and the cylinder valve is connected to the primary pressure reducer through a pipeline. The primary pressure reducer is connected to the secondary pressure reducer through a fixed tube. The device can output gas to gas-using equipment through the secondary pressure reducer.

[0007] The pipeline control assembly also includes a shut-off valve fixedly mounted on the mobile carrier. The shut-off valve is connected to the cylinder valve via a pipeline, and a gas filling port is fixedly connected to the shut-off valve.

[0008] Preferably, it also includes a pressure gauge, which is connected to the cylinder valve via a pipe and is used to display the gas pressure inside the cylinder.

[0009] Preferably, the mobile carrier includes a support frame, on which a movable wheel is rotatably mounted, and a bracket for supporting the gas cylinder is fixedly mounted on the support frame, the bracket having an arc-shaped recess that matches the outer circle of the gas cylinder;

[0010] It also includes an arc-shaped clamp, which is fixedly connected to the bracket by bolts and nuts.

[0011] Preferably, a buffer pad is fixedly provided on the arc clamp and the bracket.

[0012] Preferably, a fixing plate is fixedly provided at one end of the support frame, and a connecting rib is fixedly provided between the fixing plate and the support frame.

[0013] Preferably, the support frame is rotatably provided with support legs.

[0014] Preferably, a retaining sleeve is fixedly provided on the support frame, and the retaining sleeve is used to store and fix the support leg.

[0015] Preferably, the support frame is provided with a handle, and a handle sleeve is fixedly fitted onto the handle.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. Adopting an integrated mobile carrier design, the entire device can be easily transported, solving the problem of separating and transporting traditional gas cylinders and power generation equipment. Whether for daily household backup, temporary outdoor power supply, or gas usage for kitchen stoves, it can be flexibly moved and quickly deployed, adapting to the diverse electricity and gas needs of areas with power shortages but abundant gas resources.

[0018] 2. The gas cylinders are secured using arc-shaped clamps and buffer pads to prevent damage from impacts and ensure safe storage. The primary pressure regulator is equipped with 8.6 kg overpressure relief protection, which automatically releases pressure to prevent overpressure in the pipeline. From gas storage to graded pressure reduction, a solid safety line is built throughout the entire process to ensure stable and reliable gas filling and supply operations and reduce the risk of equipment failure and safety accidents.

[0019] In use, the gas cylinder is filled by opening the shut-off valve and filling the cylinder with gas through the filling port. The gas enters the cylinder through the pipeline. After filling the cylinder, the filling is stopped and the filling shut-off valve and cylinder valve are closed. When in operation, the cylinder valve is opened and the gas enters the first-stage pressure reducer. At the same time, the pressure gauge displays the gas pressure in the cylinder. After passing through the first-stage pressure reducer (reducing the pressure from 200-250 kg high-pressure gas to 5-6 kg medium-pressure gas), the gas enters the second-stage pressure reducer through the shaping tube. The second-stage pressure reducing valve reduces the pressure from medium-pressure gas to 1.7-5 kPa to supply the generator or stove. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-8 This utility model provides a technical solution:

[0031] Gas cylinder 1, the main gas storage unit, is placed on the support frame 21 of the mobile carrier 2. The support frame 21, as the core support structure of the mobile carrier 2, has rotatable casters 22 at its bottom for easy movement of the entire device. A bracket 23 is fixedly mounted on the frame, and the bracket 23 is welded to the support frame 21. The bracket 23 has a rounded recess 24 that matches the outer circumference of the gas cylinder 1 for initial positioning. Combined with a rounded clamp 25, the cylinder is reliably fixed to the bracket 23 via bolts and nuts. To prevent direct contact and damage between the gas cylinder 1 and the metal bracket 23, cushioning pads 26, such as rubber or silicone pads, are fixed to the rounded clamp 25 and the bracket 23 to enhance stability and protection.

[0032] A fixing plate 27 is fixedly installed at one end of the support frame 21. The fixing plate 27 and the support frame 21 are reinforced by connecting ribs 28 to improve the overall structural strength and prevent the gas cylinder 1 from slipping. The fixing plate 27 and the support frame 21 are also connected and fixed by welding. At the same time, the support leg 29 is rotatably installed on the support frame 21. When not moving, the support leg 29 is lowered to enhance the static stability of the device. It is also equipped with a retainer 210, which is an arc-shaped elastic metal sheet. It is fixedly connected to the support frame 21 by welding or bolts. When moving, the support leg 29 is retracted and locked in to avoid interference. If manual pushing and pulling is required, the support frame 21 can be equipped with a handle 211. A handle cover 212 can be put on the handle 211 to improve the grip comfort.

[0033] Piping control component 3:

[0034] The pipeline control component 3 is integrated on the support frame 21 of the mobile carrier 2 and includes a primary pressure reducer 31, a secondary pressure reducer 32, a cylinder valve 33, a pipeline 34, a shaping tube 35, a shut-off valve 36, a gas filling port 37, and a pressure gauge 38.

[0035] The above-mentioned devices are all well-known to those skilled in the art and are commonly used technologies in this field. Operators can select appropriate pipes, valves and other parts according to the actual situation. No specific model or size is limited here.

[0036] The cylinder valve 33 is installed at the outlet of the gas cylinder 1 and serves as the main control component for the gas output of the gas cylinder 1. It is connected to the first-stage pressure reducer 31 through the pipeline 34 to achieve the initial access of high-pressure gas. At the same time, the cylinder valve 33 is connected to the pressure gauge 38 through the pipeline 34 to display the gas pressure in the gas cylinder 1 in real time, and is also connected to the shut-off valve 36 to control the gas filling passage.

[0037] One end of the shut-off valve 36 is connected to the cylinder valve 33 via the pipe 34, and the other end is fixedly connected to the gas filling port 37 for external gas filling gun to replenish gas to the gas cylinder 1. When replenishing gas, the shut-off valve 36 is opened, and the gas filling gun fills gas from the gas filling port 37. The gas is stored in the gas cylinder 1 through the high-pressure pipeline. After the gas replenishment is completed, the shut-off valve 36 is closed to cut off the gas filling passage.

[0038] The first-stage pressure reducer 31 receives the high-pressure gas (200-250 kg pressure) output from the bottle valve 33, and reduces the pressure to 5-6 kg medium pressure through the internal pressure reducing structure (including a safety pressure relief device with 8.6 kg overpressure relief protection, which is a well-known technology and device in this field. No specific model or size is specified here. Operators can obtain relevant technical materials on the safety pressure relief device from technical manuals, etc.); the first-stage pressure reducer 31 is connected to the second-stage pressure reducer 32 through the shaping tube 35.

[0039] The secondary pressure reducer 32 further reduces the pressure of the medium-pressure gas output from the primary pressure reducer 31, adjusting the pressure to 1.7-5 kPa, and finally outputs it to gas-using equipment such as small generators and kitchen stoves through pipelines.

[0040] Work process and principles

[0041] External gas supply: Connect the gas gun to the gas supply port 37, open the shut-off valve 36, and the gas flows into the gas cylinder 1 through the high-pressure pipeline (shut-off valve 36 → cylinder valve 33 passage); during this period, the pressure gauge 38 displays the pressure of the gas cylinder 1 in real time, which makes it easy to judge the gas supply progress.

[0042] Gas replenishment complete: After observing that the pressure gauge 38 reaches the rated pressure of gas cylinder 1, close the gas gun and shut-off valve 36, disconnect the gas filling connection, and the gas replenishment of gas cylinder 1 is complete.

[0043] Gas usage procedure: Open valve 33 of gas cylinder 1, and high-pressure gas enters pipeline control component 3; pressure gauge 38 simultaneously displays the current pressure of gas cylinder 1, confirming that the gas is available.

[0044] Staged pressure reduction: High-pressure gas first enters the first-stage pressure reducer 31, and is reduced to medium pressure of 5-6 kg through the internal structure (in case of overpressure, the safety pressure relief device automatically releases pressure to ensure equipment safety).

[0045] The medium-pressure gas is transmitted to the secondary pressure reducer 32 via the shaping tube 35, and then reduced to the appropriate pressure of 1.7-5 kPa.

[0046] Gas Output: The secondary pressure reducer 32 outputs gas at the required pressure to the gas-consuming equipment (such as a 2.5-12KW small generator or kitchen stove) to drive the equipment. Figure 5 As shown, the secondary pressure reducer 32 is provided with a connection port for connecting to the gas-using equipment.

[0047] The support leg 29 is stored in the sleeve 210, and the moving wheel 22 is used to push the device, and the handle 211 is used to achieve convenient transportation.

[0048] Lower the support leg 29, and the support leg 29 and the moving wheel 22 together support the device to enhance static stability and adapt to power generation and gas use operation scenarios.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
