Description

Technical Field

[0001] This utility model relates to the technical field of gas collection equipment for gas ring main units, specifically a gas detection and collection mechanism for an environmentally friendly gas ring main unit. Background Technology

[0002] Ring main units can limit the placement of energized high-voltage structures, while gas ring main units can effectively prevent short circuits between energized structures, improving safety. Generally, gas ring main units require pressurization with sulfur hexafluoride (SF6). SF6 is a stable gas that is colorless, odorless, non-toxic, and non-flammable at room temperature. The purity of SF6 needs to be effectively tested. Before testing, the gas needs to be collected. Typically, the gas inside the high-pressure tank storing SF6 is directly filled into the collection tank for collection. The gas inside the collection tank is released through a one-way valve, ensuring that the collection tank is filled with the SF6 to be tested.

[0003] Currently, most gas sampling devices on the market use a single pipe and connector. When dealing with the outlet of high-pressure tanks of different sizes, it is necessary to replace the pipe connector with one that is compatible with the usage requirements.

[0004] Therefore, a gas detection and collection mechanism for an environmentally friendly gas ring network cabinet is proposed to address the above problems. Utility Model Content

[0022] 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 scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a gas detection and collection mechanism for an environmentally friendly gas ring network cabinet, including a collection box 1. A conical air inlet pipe 2 is fixedly installed in the middle of the top of the collection box 1. A valve is provided at the root of the conical air inlet pipe 2. T-shaped plates 3 are fixedly installed on both sides of the top of the collection box 1. Bearings 4 are fixedly installed on both sides of the T-shaped plates 3. A bidirectional threaded rod 5 is movably installed inside the bearing 4. The threads on the surface of the bidirectional threaded rod 5 are opposite. Both ends of the bidirectional threaded rod 5 are set as smooth rods. Arc-shaped clamping plates 6 are movably installed on both sides of the surface of the bidirectional threaded rod 5. Connecting ears 7 are fixedly installed on both sides of the arc-shaped clamping plates 6. A threaded hole 8 is opened on the front of the connecting ear 7.

[0025] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 Through the structural design of the conical intake pipe 2, T-shaped plate 3, bidirectional threaded rod 5, and arc-shaped clamping plate 6, and through the cooperation between the structures, the function of adapting to different exhaust ports is realized. Thus, the gradual characteristics of the conical intake pipe 2 can be used to flexibly adjust the fit with different exhaust ports, without the need to frequently replace adapters or connectors, reducing the complexity of operation and installation.

[0026] A limit sleeve 9 is fixedly installed at one end of the bidirectional threaded rod 5, and a transmission gear 10 is fixedly installed at the other end of the bidirectional threaded rod 5. A transmission belt 11 is movably installed on the surface of the transmission gear 10.

[0027] Reference Figure 1 , Figure 4 , Figure 5The bidirectional threaded rod 5 is limited by the limiting sleeve 9, thereby preventing the bidirectional threaded rod 5 from moving during use, thus ensuring the effective clamping of the high-pressure tank gas pipe by the arc-shaped clamping plate 6. The bidirectional threaded rods 5 on both sides can be connected by the transmission gear 10 and the transmission belt 11, so that the two sides of the arc-shaped clamping plate 6 can be adjusted synchronously in the future, thereby ensuring the stability of the arc-shaped clamping plate 6 during movement.

[0028] A positioning hole 12 is provided in the middle part of the T-shaped plate 3, and a rotating roller 13 is movably installed inside the positioning hole 12.

[0029] Reference Figure 3 and Figure 4 The positioning hole 12 facilitates the rotation space of the roller 13 and positions it. The roller 13 also facilitates the installation position of the drive gear 14.

[0030] A drive gear 14 is fixedly mounted on the surface of the rotating roller 13, a baffle 15 is fixedly mounted on one end of the rotating roller 13, and a handle 16 is fixedly mounted on the other end of the rotating roller 13.

[0031] Reference Figure 1 , Figure 4 , Figure 5 The drive gear 14 and handle 16 facilitate the user to quickly drive the transmission belt 11 to rotate.

[0032] A transparent window 17 is provided on the front of the collection box 1, and an air guide tube 18 is fixedly installed on the bottom of the collection box 1.

[0033] Reference Figure 1 and Figure 2 The transparent window 17 allows for real-time observation of the inside of the collection box 1, thus avoiding contamination of the gas by residual impurities inside the collection box 1 and ensuring the accuracy of gas detection. The gas is guided to the gas suction device 19 through the gas guide tube 18.

[0034] The bottom of the gas duct 18 is threadedly connected to a gas suction device 19, and an exhaust pipe 20 is fixedly installed at the bottom of the gas suction device 19. A manual valve 21 is provided on one side of the exhaust pipe 20.

[0035] Reference Figure 2 and Figure 5 The gas suction device 19 facilitates the generation of suction force for the gas, thereby ensuring that the gas in the high-pressure tank is fully guided to the inner cavity of the collection box 1, further preventing gas leakage at the connection between the exhaust port of the high-pressure tank and the conical air inlet pipe 2. The exhaust pipe 20 facilitates the discharge of gas inside the collection box 1 for subsequent testing, and the manual valve 21 facilitates the quick opening or closing of the exhaust pipe 20.

[0036] Working principle: When using this device, after inserting the conical air inlet pipe 2 into the exhaust port of the high-pressure tank, the handle 16 drives the rotating roller 13 to rotate, which in turn drives the drive gear 14 to rotate. The drive gear 14 generates a thrust on the transmission belt 11, causing the transmission belt 11 to rotate. The transmission belt 11 drives the two-sided transmission gears 10 to rotate, which in turn drives the bidirectional threaded rod 5 to rotate. The bidirectional threaded rod 5, in conjunction with the threaded hole 8 of the connecting ear 7, drives the arc-shaped clamping plate 6 to clamp the air pipe of the high-pressure tank, thus completing the fixation. The gas suction device 19 is then started, and the valve of the high-pressure tank is opened simultaneously. The gas inside the high-pressure tank is drawn in by the suction generated by the gas suction device 19 and enters the collection box 1 through the conical air inlet pipe 2. After closing the valve at the conical air inlet pipe 2, the collection is completed.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
