Technical Field

[0001] This utility model relates to the field of gas odorization technology, specifically a gas pipeline odorization device. Background Technology

[0002] Natural gas is widely developed and used in both industrial production and residential gas supply systems. However, due to its physical properties, natural gas is colorless and odorless or has a slight odor, which poses a potential hazard to its safe use. Gas leaks are not easily detected in time, so it is necessary to use odorizing equipment to ensure that gas leaks can be detected by people or instruments in a timely manner, allowing for prompt measures to be taken to prevent accidents.

[0003] For example, the automatic odorizing device for gas pipelines proposed in publication number CN221991577U can make the odorizer and gas more evenly mixed, make full use of the odorizer and reduce the waste of the odorizer. However, the odorizing device cannot adjust the amount of odorizer added each time according to the working conditions, and its flexibility of use is poor and needs to be improved. Therefore, we propose an odorizing device for gas pipelines. Utility Model Content

[0016] 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.

[0017] Example 1

[0018] Please see the appendix Figure 1-3 An odorizing device for gas pipelines is disclosed, used to add odorant into the main body 1 of a gas pipeline. The odorizing device includes a housing 2 mounted on the main body 1 of the gas pipeline. In this embodiment, the housing 2 can be mounted on the main body 1 using a bracket. The outer wall of the housing 2 is provided with a storage tank 3 containing the odorant. In this embodiment, the storage tank 3 has a filling port for replenishing liquid odorant into the storage tank 3. A pressure cylinder 6 is provided inside the housing 2. In this embodiment, the top of the pressure cylinder 6 is hollow. The pressure cylinder 6 is connected to the storage tank 3 through a one-way liquid inlet pipe. The liquid outlet pipe 8 extends into the gas pipeline body 1 and is connected to the atomizing nozzle 9. In this embodiment, both the one-way liquid inlet pipe and the one-way liquid outlet pipe 8 are pipes with one-way valves inside. The atomizing nozzle 9 is used to convert the odorant into atomized droplets so as to mix efficiently with the gas flowing in the gas pipeline body 1. The pressurizing cylinder 6 is provided with a matching piston. The diameter of the piston is matched with the inner diameter of the pressurizing cylinder 6. The piston is connected to the movable frame 5. The other end of the movable frame 5 is connected to the adjustable drive unit 4. The adjustable drive unit 4 is used to drive the piston to move back and forth in the pressurizing cylinder 6. The adjustable drive unit 4 drives the movable frame 5, which in turn drives the piston to reciprocate within the pressure cylinder 6. Figure 2 As shown, when the piston moves upward, the odorant in the storage tank 3 enters the pressurizing cylinder 6 through the one-way liquid inlet pipe. When the piston moves downward, it compresses the odorant in the pressurizing cylinder 6, causing the odorant to enter the atomizing nozzle 9 through the one-way liquid outlet pipe 8 and be sprayed out in the gas pipeline body 1.

[0019] The adjustable drive unit 4 includes a rod 41 rotatably disposed within the housing 2. In this embodiment, the rod 41 is rotatably connected to the inner wall of the housing 2 via bearings. A plurality of interconnected eccentric wheels 42 are slidably disposed on the outer wall of the rod 41 along its axial direction. In this embodiment, a slider is provided on the inner wall of the eccentric wheel 42, and a sliding groove for the slider is formed on the outer wall of the rod 41 along its axial direction. This facilitates the rotation of the rod 41 while the eccentric wheel 42 moves along the outer wall of the rod 41, enabling the eccentric wheel 42 to rotate. The plurality of eccentric wheels 42 are driven from the rod 41... The diameter of the rod 41 increases sequentially from one end to the other. For example, the diameters of several sets of eccentric wheels 42 are 3cm, 6cm, 9cm and 12cm respectively. The stroke of the piston driven by the eccentric wheels 42 with different diameters is different, which in turn results in different odor dosage injected into the atomizing nozzle 9. The corresponding eccentric wheel 42 and the movable frame 5 can be selected according to the required odor dosage. The top of one of the eccentric wheels 42 slides against one end of the movable frame 5. In this embodiment, a ball bearing can be embedded at one end of the movable frame 5 and slide against the top of the eccentric wheel 42.

[0020] Preferably, the vertical cross-section of the movable frame 5 in this embodiment is U-shaped, and an elastic element 7 is sleeved on the outer wall of the movable frame 5. One end of the elastic element 7 is connected to the housing 2, and the other end is connected to the movable frame 5. Optionally, the elastic element 7 in this embodiment is a spring, which is used to assist the movable frame 5 in resetting downward so that the movable frame 5 can better cooperate with the adjustable drive unit 4.

[0021] Preferably, the one-way liquid outlet pipeline 8 in this embodiment is equipped with a solenoid valve. Optionally, the solenoid valve in this embodiment is electrically connected to an external controller, and the solenoid valve can be closed when odorant is not required.

[0022] Preferably, the housing 2 in this embodiment is provided with a door 21 on one side so as to maintain or adjust the internal structure of the housing 2 and the adjustable drive unit 4.

[0023] Example 2

[0024] Please see the appendix Figure 2-3Based on Embodiment 1, the tops of several sets of eccentric wheels 42 in this embodiment are flush to allow switching between different eccentric wheels 42 corresponding to the movable frame 5. A connecting cylinder 43 is fixedly provided on the outermost eccentric wheel 42, and the connecting cylinder 43 is movably sleeved on the outer wall of the rod body 41. A mounting frame (not shown in the figure) is rotatably sleeved on the outer wall of the connecting cylinder 43. The two are rotatably connected by bearings. The mounting frame is connected to the output end of a telescopic device (not shown in the figure, such as an electric telescopic rod) located on the inner wall of the housing 2. One end of the rod body 41 is provided with a rotary drive component for driving its rotation. The telescopic device drives the connecting cylinder 43 to move along the axial direction of the rod body 41 on the outer wall of the rod body 41, switching between different eccentric wheels 42 corresponding to the movable frame 5. The telescopic device can be electrically connected to an external controller. One end of the rod body 41 is provided with a rotary drive component for driving its rotation. Optionally, two embodiments of the above-mentioned rotary drive component are provided below: In the first embodiment, the rotary drive includes a connecting block 10 disposed within the gas pipeline body 1. The diameter of the connecting block 10 is adapted to the inner diameter of the gas pipeline body 1. A cavity is formed within the connecting block 10, and an impeller 11 is rotatably disposed within the cavity. In this embodiment, the vertical cross-section of the cavity is circular. An air inlet and an air outlet communicating with the cavity are respectively formed on both sides of the connecting block 10, and both the air inlet and the air outlet correspond to the impeller 11. When the gas flows within the gas pipeline body 1, it enters the cavity from the air inlet, thereby driving the impeller 11 to rotate, and then exits from the air outlet. The inner wall of the cavity is open. A groove is provided, and an atomizing nozzle 9 is located in the groove. The atomizing nozzle 9 converts the odorant into atomized droplets that are scattered in the cavity and, together with the gas, drives the impeller 11 to rotate, making the odorant and gas more evenly mixed and reducing the waste of odorant. One end of the shaft of the impeller 11 passes through the connecting block 10 and the gas pipeline body 1 and is connected to one end of the rod 41. Rubber seals can be provided at the connection points between the shaft of the impeller 11 and the connecting block 10 and the gas pipeline body 1 for sealing. In this embodiment, the shaft of the impeller 11 and one end of the rod 41 can be connected by a sprocket drive assembly (including sprockets and chains).

[0025] In the second embodiment, the rotary drive includes a rotary device disposed on the outer wall of the housing 2 and connected to one end of the rod 41. The rotary device is, for example, a motor, which is a conventional device in the art and will not be described in detail here.

[0026] Example 3

[0027] Please see the appendix Figure 2Based on Embodiment 1, the storage tank 3 in this embodiment is equipped with a stirring element 12. In this embodiment, the stirring element 12 includes a stirring rod and stirring blades disposed on the outer wall of the stirring rod. Of course, it is not limited to this type. The stirring element 12 is connected to one end of a threaded rotating rod 13.

The connecting frame 14 is fixedly connected to the movable frame 5. A threaded sleeve is fixedly inserted on the storage tank 3, and the threaded sleeve is threaded on the outside of the threaded rotating rod 13. Through the threaded engagement of the threaded sleeve and the threaded rotating rod 13, the movable frame 5 can drive the threaded rotating rod 13 to rotate upward or rotate upward through the connecting frame 14 to stir the odorant in the storage tank 3, so as to prevent the odorant from settling in the storage tank 3 and improve the quality of the odorant.
