Description

Technical Field

[0001] This utility model specifically relates to a portable water gas collection device, belonging to the field of water gas collection technology. Background Technology

[0002] Water gas collection refers to the capture of dissolved or released gases from water bodies, applied to environmental monitoring, industrial optimization, and scientific research. Currently, water gas collection mostly involves collecting water samples from rivers or water bodies, then sealing and transporting them to a laboratory to separate the dissolved and released gases. This method is inconvenient for on-site operations, affecting the accuracy of water gas collection. Furthermore, most current water gas collection devices are large in size, requiring multiple people to carry them, which is inconvenient. When not in use, some electrical components are exposed and easily damaged by impacts, affecting their service life. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a portable water gas collection device, which is convenient to carry to water sites for in-situ sampling of dissolved gases in water, thereby improving detection accuracy and enhancing protection when not in use.

[0004] This utility model achieves the above-mentioned objective through the following technical solution: a portable water gas collection device, comprising a degassing main unit, a power supply and control main unit fixedly installed at the lower end of the degassing main unit, an I-shaped mounting ring fixedly installed on the outer side of the upper end of the degassing main unit, and an arc-shaped gas collection bladder fixedly installed inside the mounting ring, a pull rod inserted into the mounting ring, a caster wheel fixedly installed at the lower end of the power supply and control main unit, and an air pump, a water pump, and a vacuum pump fixedly installed at the upper end of the degassing main unit, the air outlet of the air pump being connected to the gas collection bladder, and the upper end of the mounting ring... The end is fitted with a cover plate. When carrying, the pull rod is pulled out and, in conjunction with the universal wheels, it can be pulled like a suitcase for easy carrying. When in use, the pull rod is inserted into the lower end of the mounting ring, and the cover plate is fitted onto the lower end of the power supply control host to support the whole and improve stability when placed. Water from the river is pumped into the degassing host through the water pump to separate the dissolved gases in the water. After separation, the gas is pumped into the gas collection bag for temporary storage, which is convenient for in-situ operation and easy to operate and use.

[0005] Furthermore, the air inlet of the air pump is connected to the interior of the degassing unit, and a three-way piston is fixedly installed at the outlet of the water pump. One end of the three-way piston is connected to the interior of the degassing unit, and the other end of the three-way piston is fixedly installed with an overflow pipe. One end of the vacuum pump is connected to the interior of the degassing unit. When separating gases in the water, the water pump draws water from the river into the interior of the degassing unit through the three-way piston and the water pump. The vacuum pump creates a negative pressure inside the degassing unit, and the dissolved gases in the water are separated under the negative pressure. Then, the separated gases are drawn into the gas collection bag by the air pump for sealing, which facilitates operation and makes it convenient to collect gases from the water.

[0006] Furthermore, a storage box for placing an external water pumping hose is fixedly installed on the upper end of the degassing unit, and a sleeve is fixedly installed on the mounting ring. The pull rod has a U-shaped structure and is sleeved on the sleeve. The storage box facilitates the storage of accessories during use, and the sleeve facilitates the position adjustment of the pull rod. The end of the pull rod has a T-shaped structure to prevent the pull rod from detaching from the sleeve.

[0007] Furthermore, a gas sampling pipe with a valve is fixedly installed on one side of the lower end of the mounting ring, and one end of the gas sampling pipe is connected to the inside of the gas collecting bag, so as to facilitate the collection of gas inside the gas collecting bag during testing.

[0008] Furthermore, a drain pipe for discharging waste liquid is fixedly installed on one side of the degassing unit, and a ball valve is fixedly installed on the drain pipe. After the collection is completed, the water in the degassing unit is discharged through the drain pipe.

[0009] Furthermore, the upper end of the mounting ring is fixedly mounted with upper claws in a circumferential array, and the inner side of the cover plate is fixedly mounted with clips that match the upper claws in a circumferential array. The cover plate is snapped onto the upper claws by the clips. When carried, the cover plate protects the electrical components at the upper end from bumps and knocks.

[0010] Furthermore, the lower end of the power supply control host is fixedly installed with lower jaws that match the upper jaws in a circular array. During use, the cover plate supports this technical solution and improves the stability during placement.

[0011] Furthermore, the diameter of the power supply control host is the same as the diameter of the mounting ring. The power supply control host supplies power to the degassing host, the air pump, the water pump, and the vacuum pump and controls their operation, making it easy to carry and use externally and convenient to operate.

[0012] Beneficial effects: The use of a vertically movable pull rod, combined with omnidirectional wheels, makes it easy to carry like a suitcase, improving convenience when carrying. The cover protects electrical components when not in use and improves stability when in use. The air bladder allows for temporary storage after gas separation, reducing the scattered nature of carried items and making it convenient to use. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1-6As shown, a portable water gas collection device includes a degassing main unit 1. A power supply and control main unit 2 is fixedly installed at the lower end of the degassing main unit 1. An I-shaped mounting ring 3 is fixedly installed on the outer side of the upper end of the degassing main unit 1, and an arc-shaped gas collection bladder 4 is fixedly installed inside the mounting ring 3. A pull rod 5 is inserted into the mounting ring 3. A caster wheel 6 is fixedly installed at the lower end of the power supply and control main unit 2. An air pump 7, a water pump 8, and a vacuum pump 9 are fixedly installed at the upper end of the degassing main unit 1. The diameter of the power supply and control main unit 2 is the same as the diameter of the mounting ring 3. The power supply and control main unit 2 provides power to the degassing main unit 1 and controls the opening and closing of the air pump 7, water pump 8, and vacuum pump 9, making it easy to carry for external use. No external power supply is required, making it easy to operate. The air outlet of the air pump 7 is connected to the air collection bag 4. The upper end of the mounting ring 3 is fitted with a cover plate 10. When carrying, the pull rod 5 is pulled out and used with the universal wheels 6 to pull the solution like a suitcase, making it easy to carry. When in use, the pull rod 5 is inserted into the lower end of the mounting ring 3, and the cover plate 10 is fitted onto the lower end of the power supply control host 2 to support the whole and improve stability when placed. Water from the river is pumped into the degassing host 1 by the water pump 8 to separate the dissolved gas in the water. After separation, the gas is pumped into the air collection bag 4 by the air pump 7 for temporary storage, which is convenient for on-site operation and easy to use.

[0022] As a technical optimization of this utility model, the air inlet of the air pump 7 is connected to the interior of the degassing host 1, and a three-way piston 11 is fixedly installed at the outlet of the water pump 8. One end of the three-way piston 11 is connected to the interior of the degassing host 1, and an overflow pipe 12 is fixedly installed at the other end of the three-way piston 11. One end of the vacuum pump 9 is connected to the interior of the degassing host 1. When separating gases in water, the principle is similar to the technology in the existing patent publication number CN111006913A (Adjusting Portable Water-Soluble Gas Sampling Device and Dissolution Separation, Water-Soluble Gas Collection Method). In this technical solution, an elastic bulb is installed inside the degassing host 1, and the elastic bulb is connected to the vacuum pump 9. In use, the interior of the elastic bulb is first inflated to make the bulb expand, and the three-way piston 11 and the water pump 8 are opened. The water pump 8 then pumps the water from the river... Water is drawn into the degassing unit 1 through the three-way piston 11, filling the interior of the degassing unit 1 with water. After the water overflows through the overflow pipe 12, the three-way piston 11 is closed, creating a sealed state inside the degassing unit 1. The vacuum pump 9 then evacuates the interior of the elastic bladder, creating a negative pressure inside the degassing unit 1. Under this negative pressure, the dissolved gas in the water is separated, with the separated gas located above the degassing unit 1 and the water located below. The separated gas is then drawn into the gas collection bladder 4 by the air pump 7 for sealing. The air pump 7 is a self-closing gas delivery pump to ensure the airtightness of the degassing unit 1 under negative pressure. After the gas collection is complete, the three-way piston 11 is opened, and the water inside the degassing unit 1 is discharged, completing the water-gas collection operation.

When pumping water, the external water pumping hose is connected to the inlet end of the water pump 8, and the other end is placed in the river. A filter screen is built into one end of the external water pumping hose to prevent foreign objects from entering the degassing unit 1. The sleeve 14 facilitates the adjustment of the position of the pull rod 5. The end has a T-shaped structure to prevent the pull rod 5 from detaching from the sleeve 14. A gas sampling pipe 15 with a valve is fixedly installed on one side of the lower end of the mounting ring 3, and one end of the gas sampling pipe 15 is connected to the inside of the gas collecting bag 4. After the gas in the water body is sampled by this technical solution, it is carried to the laboratory. The gas in the gas collecting bag 4 can be discharged through the gas sampling pipe 15 for easy detection. A drain pipe 16 for discharging waste liquid is fixedly installed on one side of the degassing host 1, and a ball valve is fixedly installed on the drain pipe 16. After the sampling is completed, the ball valve is opened to facilitate the discharge of water in the degassing host 1 through the drain pipe 16.

[0024] As a technical optimization of this utility model, the upper end of the mounting ring 3 is fixedly mounted with upper claws 17 in a circular array, and the inner side of the cover plate 10 is fixedly mounted with clips 18 that match the upper claws 17 in a circular array. The cover plate 10 is snapped onto the upper claws 17 by the clips 18. When carried, the cover plate 10 can protect the air pump 7, water pump 8 and vacuum pump 9 from bumps. The lower end of the power supply control host 2 is fixedly mounted with lower claws 19 that match the upper claws 17 in a circular array. When in use, the cover plate 10 is snapped onto the lower claws 19 by the clips 18 to support this technical solution and improve the stability when placed.
