Technical Field

[0001] This application relates to the field of instrument testing, and in particular to a portable gas filling testing device. Background Technology

[0002] Currently, existing gas detection devices generally include a gas cylinder, a gas pipe, and a release device. By releasing the gas in the gas cylinder and transporting it to the space to be detected through the gas pipe, the gas detected by the gas alarm is released, forming a certain concentration of gas in the space to be detected. This determines the corresponding alarm time of the gas alarm, and judges whether the alarm time and alarm concentration value of the gas alarm meet the working requirements, thereby determining that the detection function of the gas alarm can operate normally.

[0003] Regarding the aforementioned technologies, the inventors discovered that when conducting in-home inspections, inspectors need to carry a bulky gas alarm detector, which is inconvenient for inspectors to carry. Utility Model Content

[0004] To address the shortcomings of existing gas alarm detectors, which are inconvenient for testing personnel to carry, this application provides a portable gas refueling detection device.

[0005] This application provides a portable gas refueling detection device, which adopts the following technical solution:

[0006] A portable gas filling and detection device includes: a housing container, a gas cylinder, a gas distribution module, and a support rod. The gas distribution module is located inside the housing container and is connected to the gas cylinder via a gas pipe. The support rod is fixedly connected to one surface of the housing container.

[0007] By adopting the above technical solution, placing the gas distribution module inside the enclosure and the power supply module in the connecting rod, the size of the gas alarm detection device is greatly reduced. At the same time, by grabbing the support rod connected to the bottom of the enclosure, the testing personnel can cover the alarm to be tested, which is located on the side wall or roof, thus facilitating the carrying and testing by the testing personnel.

[0008] Preferably, the cover container is an open container.

[0009] By adopting the above technical solution, the cover container is an open container, which makes it easy to cover the alarm device to be tested located on the side wall or roof, thereby facilitating the inspection by the inspectors.

[0010] Preferably, the opening of the cover container has flexible rubber.

[0011] By adopting the above technical solution, the opening of the enclosure has flexible rubber, which allows the enclosure to fit tightly against the wall when it covers the alarm to be tested located on the side wall or roof, thus overcoming the possibility of gas leakage inside the enclosure due to uneven wall surfaces.

[0012] Preferably, a power supply module is installed inside the support rod, and a charging interface is installed on the connecting rod.

[0013] By adopting the above technical solution, the power supply module is built into the connecting rod, which allows the entire device to work for a period of time without relying on an external power source, enhancing the device's autonomy and portability. At the same time, placing the power supply module in the support rod greatly reduces the size of the portable gas filling and testing device.

[0014] Preferably, the gas distribution module is connected to the power supply module inside the connecting rod.

[0015] By adopting the above technical solution, the gas distribution module is connected to the power supply module, so that the power supply module can supply power to the gas distribution module, eliminating the need for other power supply devices to provide power to the gas distribution module, thereby further reducing the size of the portable gas filling and detection device.

[0016] Preferably, the gas distribution module includes a controller, a solenoid valve, a pressure regulating valve, a gas detection unit, a sound detection unit, a communication unit, a stirring unit, and an image acquisition unit.

[0017] By adopting the above technical solution, the controller controls the switching of each unit of the solenoid valve, the stirring unit stirs the gas inside the container evenly, the gas detection unit monitors the gas concentration inside the container, and the sound detection unit detects the alarm status of the alarm device inside the container to determine whether the alarm device is alarming normally, thereby improving the accuracy of the portable gas filling detection device.

[0018] Preferably, the controller is connected to the solenoid valve, the pressure regulating valve, the gas detection unit, the sound detection unit, the stirring unit, and the image acquisition unit, respectively, and the communication unit is connected to the gas detection unit, the sound detection unit, and the image acquisition unit, respectively.

[0019] By adopting the above technical solution, the controller is directly connected to solenoid valves, pressure regulating valves, etc., enabling the system to automatically adjust its working state according to preset parameters or real-time data, such as controlling gas flow and pressure, which greatly improves the automation level and control accuracy of on-site detection and reduces human error and mistakes.

[0020] Preferably, the gas cylinder stores high-pressure, high-purity gas of the same type as the gas detected by the alarm device under test.

[0021] By adopting the above technical solution, a gas that is the same as that in a gas alarm can be stored. It is small in size and easy to carry.

[0022] In summary, this application includes at least the following beneficial technical effects:

[0023] 1. By placing the gas distribution module inside the enclosure and the power supply module in the connecting rod, the size of the gas alarm detection device is greatly reduced.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail.

[0033] This application discloses a portable gas filling detection device.

[0034] Example 1

[0035] Reference Figure 1 A portable gas filling and detection device includes a housing container 110, a gas cylinder 120, a gas distribution module 130, and a support rod 140. The gas distribution module 130 is located inside the housing container 110 and is connected to the gas cylinder 120 via a gas pipe 150. The gas cylinder 120 is located outside the housing container 110. The support rod 140 is fixedly connected to one surface of the housing container 110. The housing container 110 is an open container with flexible rubber at the opening. The gas cylinder 120 stores high-pressure, high-purity gas of the same type as the gas detected by the alarm device under test.

[0036] The implementation principle of a portable gas refueling detection device according to an embodiment of this application is as follows: The operator holds the support rod 140 to cover the alarm to be detected, located on a side wall or roof, with the cover container 110. The flexible rubber at the opening of the cover container ensures a tight fit with the wall, thus forming a sealed space around the alarm. The operator then clicks "Start Detection" on the electronic device, which sends a "Start Detection" command to the gas distribution module 130 inside the cover container 110. The gas distribution module 130 controls the gas in the gas cylinder 120 to be transferred through the gas pipe 150 to the cover container 110, simulating a gas leak scenario within the sealed space corresponding to the cover container 110. The alarm status of the alarm inside the cover container 110 is then checked to determine whether the alarm is functioning correctly. This embodiment greatly reduces the size of the gas alarm detection device by placing the gas distribution module 130 inside the enclosure container 110. At the same time, the testing personnel can use the support rod 140 connected to the enclosure container 110 to test the alarm to be tested, which makes it convenient for staff to test the alarms installed in various positions on the wall.

[0037] Example 2

[0038] Reference Figure 2 and Figure 3 The difference between this embodiment and embodiment 1 is that: a power supply module 141 is installed inside the support rod 140 of the portable gas filling detection device, the gas distribution module 130 is connected to the power supply module 141 inside the support rod 140, and a charging interface 142 is installed on the support rod 140.

[0039] The implementation principle of a portable gas filling detection device according to an embodiment of this application is as follows: a power supply module 141 is installed inside the support rod 140, and the gas distribution module 130 is connected to the power supply module 141 inside the support rod 140. Power is provided to the gas distribution module 130 and the like without increasing the volume of the portable gas filling detection device. A charging interface 142 is installed on the support rod 140 so as to perform plug-in detection or charge the power supply module 141 when the power of the power supply module 141 is insufficient.

[0040] Example 3

[0041] Reference Figure 4 The difference between this embodiment and Embodiment 2 is that the gas distribution module 130 includes a controller 131, a solenoid valve 132, a pressure regulating valve 133, a gas detection unit 134, a sound detection unit 135, a communication unit 136, a stirring unit 137, and an image acquisition unit 138. The controller 131 is connected to the solenoid valve 132, the pressure regulating valve 133, the gas detection unit 134, the sound detection unit 135, the stirring unit 137, and the image acquisition unit 138, respectively. The communication unit 136 is connected to the gas detection unit 134, the sound detection unit 135, and the image acquisition unit 138, respectively. (See [link to previous section]). Figure 5 The electronic device is connected to the communication unit 136 and the controller 131 respectively.

[0042] The implementation principle of a portable gas refueling detection device according to an embodiment of this application is as follows: After the electronic device sends a detection command, the controller 131 controls the image acquisition unit 138 to acquire the appearance image and nameplate image of the alarm to be tested. The electronic device receives the appearance image and nameplate image, compares the image with the images of each gas alarm to determine the model of the alarm to be tested, and obtains the detection gas type corresponding to the model, the detection gas concentration corresponding to the detection gas type, and the corresponding allowable error, so as to obtain the detection gas concentration range and minimum gas release volume of the alarm to be tested. When the portable gas refueling detection device is in working state, the power supply module 141 provides power to each unit in the gas distribution module 130. At the same time, the operator can set internal operating parameters such as gas pressure and gas flow rate through the electronic device. After the electronic device sends a detection command, the controller 131 controls the flow controller 131 to adjust to the preset value, and then the controller 131 controls the solenoid valve 132 to open, allowing gas to flow out from the gas cylinder 120. During the gas release process, the stirring unit 137 stirs the gas inside the cover container 110 to make the gas concentration inside the cover container 110 uniform. After the gas release is completed and the minimum gas volume is released, the controller 131 controls the gas detection unit 134 to detect the gas concentration inside the enclosure container 110. If the gas concentration inside the enclosure container 110 meets the requirements at this time, the controller 131 controls the solenoid valve 132 to close and stop the gas release. If the gas concentration inside the enclosure container 110 meets the requirements at this time, the controller 131 controls the solenoid valve 132 to open and continue to release gas. The sound detection unit 135 can detect the sound when the alarm under test sounds, thereby obtaining the gas concentration inside the enclosure container 110 when the alarm under test sounds, so as to determine whether the alarm under test meets the requirements.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
