Description

Technical Field

[0001] This utility model relates to the field of sulfur hexafluoride gas capture technology, and in particular to a portable sulfur hexafluoride gas capture device. Background Technology

[0002] Sulfur hexafluoride (SF6) gas, as a high-performance insulating and arc-quenching medium, is widely used in power equipment and other fields. Its efficient recovery and capture are of great significance for resource recycling and the stable operation of related fields. With the increasing demand for portable devices, SF6 gas capture devices that can be flexibly moved and adapted to different scenarios have gradually become the focus of research and application. The entire device is set at the outlet of the ventilation pipe, and the absorption hood is stably stationed near the outlet of the leaking gas, thereby achieving effective capture and centralized collection of the exhaust gas and preventing the gas from spreading in the air. It has the characteristics of being portable, flexible and highly adaptable.

[0003] In existing technologies, the gas absorption process lacks effective intelligent control. The gas absorption device cannot be automatically started and stopped by the controller, and the tank status needs to be manually monitored. Negligence can easily lead to excessive gas pressure or insufficient gas capture. The direction of the suction hood is fixed, making it difficult to flexibly adjust the absorption range and reducing the gas capture efficiency. Utility Model Content

[0004] This invention aims to solve the problem of the lack of effective control in the existing gas absorption process. It addresses the issue that existing devices cannot automatically start and stop the gas absorption device through a controller, requiring manual monitoring of the tank status, which can easily lead to excessive gas pressure or insufficient gas collection due to negligence. It also solves the problem that the suction hood is difficult to fix in a flexible manner according to the position of the SF6 exhaust pipe, thus reducing the gas collection efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A portable sulfur hexafluoride gas capture device includes a tank assembly, a capture structure, and a moving structure. The tank assembly is mounted on the movable structure, and the trapping structure is mounted on the tank assembly. The tank assembly includes a tank. The trapping structure includes a sealing cap, a fixing tube, a rotating platform, an air pump, and bolts. The fixed tube is installed on the top of the tank through a sealing cap, the rotating platform is rotatably installed on the top of the sealing cap, multiple handles are fixedly installed at equal intervals on the side wall of the rotating platform, the air pump is installed on the rotating platform through a fixed sleeve, and the air pump is installed with a suction hood through a gooseneck tube.

[0006] A controller, a smart pressure gauge, and an exhaust valve are fixedly installed on the side walls of the tank. The smart pressure gauge and the exhaust valve are connected to the interior of the tank. A flange is fixedly installed on the outer wall of the top of the tank.

[0007] The sealing cap is fixedly installed on the flange by multiple bolts. The fixing pipe is fixedly installed in the middle position of the sealing cap. The fixing pipe passes through the sealing cap and communicates with the inside of the tank. A one-way valve is installed on the fixing pipe.

[0008] The fixed sleeve is fixedly installed on the top of the rotating platform, the top end of the fixed tube extends into the fixed sleeve, and the fixed tube and the fixed sleeve are movably connected, with a sealing ring provided at the movable connection; both the fixed tube and the fixed sleeve are magnetic tubes.

[0009] The air outlet of the air pump is fixedly connected to the fixed sleeve, one end of the gooseneck tube is fixedly connected to the air inlet of the air pump, and the suction cover is fixedly installed at the other end of the gooseneck tube.

[0010] The movable structure includes a base plate, casters, and push rods. The casters are rotatably mounted at the four corners of the bottom of the base plate, and the push rods are fixedly connected to the side wall of the base plate. The top of the base plate is provided with mounting grooves and sliding grooves.

[0011] The mounting groove is rotatably connected to a bidirectional lead screw, one end of which is fixedly connected to a turntable. A clamping block is threaded onto the bidirectional lead screw, and sliders are fixedly connected to the bottom of both ends of the clamping block. Each slider extends into each slide groove, and the slider and the slide groove slide in contact.

[0012] The controller is electrically connected to the smart pressure gauge.

[0013] The controller is electrically connected to the suction pump.

[0014] The slide groove is configured as two grooves, and each slide groove is symmetrically arranged on both sides of the mounting groove.

[0015] The beneficial effects of this utility model are: 1. Through the designed trapping structure, the controller can automatically start and stop the suction pump. The intelligent pressure gauge monitors the tank pressure in real time and feeds it back to the controller, ensuring safe gas storage. The suction hood direction can be adjusted by manually turning the handle. When the suction hood rotates, the position and angle of the suction hood inlet will change, and the suction position of the suction hood will also be adjusted accordingly. The overall operation is flexible, efficient, and highly practical. The fixing tube and fixing sleeve are movably connected together by magnetic adsorption, which allows the fixing tube and fixing sleeve to be easily separated and disassembled.

[0016] 2. Through the designed moving structure, the rotating turntable drives the bidirectional lead screw, which can precisely control the clamping block to slide in the slide groove with the help of the slider, thereby stably clamping and fixing the tank. This effectively prevents the tank from shaking or tipping over during the movement of the device, ensuring safety. The moving structure with push rods and casters makes the transfer operation of the entire device convenient and labor-saving, and can flexibly adapt to different working scenarios, improving the portability and operating efficiency of the device.

[0022] The model number selected in this patent is for illustrative purposes only, and is not intended to restrict the use of this particular model of instrument.

[0023] Example 1 Refer to attached figure Figure 1 - Appendix Figure 5 This is the first embodiment of the present invention, providing a portable sulfur hexafluoride gas capture device, including a tank assembly 1, a capture structure 2, and a moving structure 3. The tank assembly 1 is mounted on the moving structure 3, and the capture structure 2 is mounted on the tank assembly 1. The tank assembly 1 includes a tank 11, and a controller 12, a smart pressure gauge 13, and an exhaust valve 14 are fixedly mounted on the side walls of the tank 11.

A flange 15 is fixedly mounted on the outer wall of the top of the tank 11. The controller 12 and the smart barometer 13 are electrically connected.

[0024] The controller 12 was purchased from Shenzhen Haoyue Technology Co., Ltd., model ESP32 controller, along with its related power supply and circuitry.

[0025] The intelligent barometer 13 was purchased from TEXG Instruments Technology Co., Ltd., model MHY-13791 digital barometer, along with its related power supply and circuitry.

[0026] The suction pump 206 was purchased from Guangzhou Chunlong Building Materials Trading Co., Ltd., model MP-Σ100HNⅡ air suction pump and its related power supply and circuit.

[0027] The gooseneck tube 207 was purchased from Shannuo Lighting Processing Factory in Guzhen Town, Zhongshan City. Model: 360-degree metal flexible gooseneck tube.

[0028] The one-way valve 201 was purchased from Yangzhou Zhuocheng Pneumatic Technology Co., Ltd. Model: One-way check valve. The one-way valve 201 uses the flow pressure of gas to open and close the valve.

[0029] The SF6 infrared thermal imaging leak detector was purchased from Yotai Power Equipment (Shanghai) Co., Ltd., model SF6 gas infrared thermal imaging leak detector - quantitative leak detector, along with its related power supply and circuitry.

[0030] The trapping structure 2 includes a sealing cover 201, a rotating platform 203, an air suction pump 206, and bolts 209. The sealing cover 201 is fixedly mounted on the flange 15 by bolts 209. A fixing pipe 202 is fixedly mounted in the middle of the sealing cover 201. A one-way valve 210 is installed on the fixing pipe 202. The fixing pipe 202 passes through the sealing cover 201 and communicates with the inside of the tank 11. The rotating platform 203 is rotatably mounted on the top of the sealing cover 201. The fixed tube 202 is inside the rotating platform 203. The handles 204 are fixedly mounted at equal intervals on the side wall of the rotating platform 203. The fixed sleeve 205 is fixedly mounted on the top of the rotating platform 203. The top of the fixed tube 202 extends into the fixed sleeve 205, and the fixed tube 202 and the fixed sleeve 205 are movably connected. A sealing ring is provided between the fixed tube 202 and the fixed sleeve 205 to prevent gas leakage. By setting a one-way valve 210, gas can only enter the fixed tube 202 from the fixed sleeve 205 and cannot flow in reverse. The outlet end of the suction pump 206 is fixedly connected to the fixed sleeve 205. The inlet end of the suction pump 206 is fixedly connected to the gooseneck tube 207. The free end of the gooseneck tube 207 is fixedly mounted with a suction cover 208. The suction cover 208, the gooseneck tube 207, the suction pump 206 and the fixed sleeve 205 are internally connected. The controller 12 is electrically connected to the suction pump 206.

[0031] Preferably, the fixing tube 202 is made of a magnetic tube. The fixing sleeve 205 is made of a magnetic tube. The fixing tube 202 and the fixing sleeve 205 are movably connected together by magnetic attraction, which makes it easy to separate and disassemble the fixing tube 202 and the fixing sleeve 205.

[0032] During use, staff used an SF6 infrared thermal leak detector to check for SF6 gas in the factory's ventilation duct. Upon detecting an SF6 leak, staff moved the device to the vicinity of the ventilation duct and stretched, bent, and shaped the gooseneck tube 207 to ensure the suction hood 208 remained stably positioned and connected to the gas outlet of the ventilation duct. The controller 12 then activated the suction pump 206, creating a negative pressure within the gooseneck tube 207, which in turn caused the suction hood 208 to absorb the external sulfur hexafluoride gas. The process was completed by manually turning the handle 20... 4. The rotating table 203 rotates on the sealing cover 201, changing the direction of the suction hood 208. The sucked SF6 gas enters the tank 11 for storage through the gooseneck tube 207, the fixed sleeve 205 and the fixed tube 202. The intelligent pressure gauge 13 monitors the internal pressure of the tank 11 in real time. When the pressure reaches the set threshold, the data is transmitted to the controller 12, and the controller 12 immediately shuts off the suction pump 206. When it is necessary to discharge, the power supply of the controller can be cut off, and then the staff can manually open the exhaust valve 14 to discharge the stored sulfur hexafluoride gas, thereby realizing the discharge of SF6 tail gas.

[0033] When the SF6 infrared thermal leak detector cannot detect SF6 gas, the SF6 gas capture process can be terminated.
