Description

Technical Field

[0001] This utility model relates to the field of combustible gas detection technology, specifically to a linkage structure for a fan and detector in a liquefied gas workshop. Background Technology

[0002] The liquefied petroleum gas (LPG) filling workshop is a high-risk area within an LPG station, involving gas filling and cylinder testing. An LPG station is a facility that produces, stores, and sells LPG, including areas such as storage tank areas, heat exchange stations, and filling workshops. Due to the flammable and explosive nature of LPG, the filling workshop is classified as a high-risk area. An accident could not only cause property damage but also result in personal injury or death. To ensure the safe and stable operation of the LPG filling workshop, a series of measures are needed to strengthen safety management, such as rationally planning the layout of the LPG station, installing good ventilation systems and fire-fighting facilities, and ensuring timely handling of gas leaks, fires, and other accidents.

[0003] The existing ventilation system in the LPG filling workshop is not linked to the detection instrument, and the fans can only be started and stopped manually. If a leak occurs in the LPG filling workshop, there is a risk of fire due to untimely start-up of the fans or untimely shutdown of the fans, resulting in the fans running continuously and wasting resources. Utility Model Content

[0004] The purpose of this utility model is to provide a linkage structure for fans and detectors in liquefied gas workshops, so as to solve the problems that in the existing ventilation system of liquefied gas filling workshops, the fans are not linked with the detectors, resulting in leaks in the liquefied gas filling workshop, fires caused by untimely start-up of manually controlled fans, or fans that are not turned off in time, resulting in the fans running continuously and wasting resources.

[0005] To achieve the above objectives, the basic solution provided by this utility model is as follows: a linkage structure for a fan and detector in a liquefied gas workshop, including an explosion-proof fan, a controller host electrically connected to the explosion-proof fan, an early warning component for prompting the signal on the controller host, a liquefied gas detector on the early warning component, a signal connection between the controller host and the liquefied gas detector, the controller host controlling the explosion-proof fan according to the liquefied gas concentration in the workshop, and a fixing component for installing the liquefied gas detector on the liquefied gas detector.

[0006] The principle and beneficial effects of this utility model are as follows: During installation, several fixed components are installed in the LPG filling workshop according to actual needs. LPG detectors are then installed on these fixed components. The explosion-proof fan, controller, and early warning components are then electrically connected. When the LPG detector detects a leak, it sends a signal to the controller via a 4-20mA current. Upon receiving the signal, the controller classifies the LPG concentration and controls the airflow of the explosion-proof fan accordingly. Simultaneously, the early warning components alert personnel in the LPG filling workshop to promptly ventilate the leaking LPG, increasing workshop safety. When the LPG detector fails to detect any LPG in the filling workshop, the controller stops the fan, preventing it from running continuously and saving resources.

[0007] Option 2, a preferred option of the basic scheme, includes an indicator light and a warning light. The indicator light is connected in series with the LPG detector, and the indicator light is connected in series with the controller host. When the LPG detector detects a leak of LPG, the indicator light illuminates. When the controller host controls the explosion-proof fan according to the LPG concentration, the indicator light illuminates different colors according to the controller host's classification, making it easier for staff to determine the LPG concentration range based on the different colored indicator lights.

[0008] Option 3, the preferred option of the basic option, has an alarm connected in series on the controller host; the alarm is a buzzer, and different frequencies are set on the buzzer to emit different sounds according to the level of the controller host, so that the staff can judge the liquefied gas concentration range by different sounds.

[0009] Option 4, an optimal choice from the basic option, includes several mounting pipes, a liquefied gas detector, and a threaded connection between the mounting pipes and the detector. A plug is detachably connected to each mounting pipe. Several mounting pipes are installed in the liquefied gas filling workshop according to actual needs, and the liquefied gas detector is then threaded onto the mounting pipes. This facilitates replacement and maintenance of the liquefied gas detector when it malfunctions. The plug can be used to seal the pipe opening when the detector is not needed, preventing rust or debris from entering and affecting subsequent installations.

[0010] Option 5, which is the preferred option of option 4, has a connecting ring fixed to the plug, and a connecting rope tied to the connecting ring. The connecting rope is tied to the installation pipe. The plug is tied to the installation pipe by the connecting rope to prevent the plug from being lost.

[0011] Option 6, which is the preferred option of the basic option, has an explosion-proof switch connected in parallel on the controller host. The explosion-proof switch can be used to manually switch the explosion-proof fan when the controller host fails, and can also be used to switch the explosion-proof fan on and off when ventilation is needed in the workshop during daily operations.

[0015] Example

[0016] like Figure 1 The diagram shows a linkage structure for a fan and detector in a liquefied petroleum gas (LPG) workshop. The fan is an explosion-proof fan 1 (model BT-4). A controller host 6 (model KB-500) is electrically connected to the fan 1. An alarm 8 (model GTQBS03) is connected in series with the controller host 6. The controller host 6 is equipped with a warning component, which includes an indicator light 301 and an indicator light 302. The indicator light 301 is connected in series with the LPG detector 2, and the indicator light 302 is connected in series with the controller host 6. The device is equipped with a liquefied petroleum gas (LPG) detector 2. The controller host 6 is connected to the LPG detector 2 via a signal connection. The controller host 6 controls the explosion-proof fan 1 according to the LPG concentration classification in the workshop. The LPG detector 2 is equipped with a fixing component for mounting the LPG detector 2. The fixing component includes several mounting pipes 401. The LPG detector 2 is threadedly connected to the mounting pipes 401. A plug 402 is detachably connected to the mounting pipe 401. A connecting ring 404 is fixedly connected to the plug 402. A connecting rope 403 is tied to the connecting ring 404. The connecting rope 403 is tied to the mounting pipe 401.

[0017] The implementation method of this embodiment is as follows: During installation, several installation pipes 401 are installed in the LPG filling workshop according to actual needs. Then, the plugs 402 on the installation pipes 401 are removed, and the LPG detector 2 is threaded onto the installation pipes 401. Next, the indicator light 301 and the LPG detector 2 are connected in series. Then, the LPG concentration classification, the air volume of the explosion-proof fan 1, the color of the indicator light 302, and the frequency of the alarm 8 in the controller host 6 are set so that the air volume of the explosion-proof fan 1 corresponds to the LPG concentration classification. Indicator light 302 illuminates in different colors according to the liquefied gas concentration level, and alarm 8 emits different sounds according to the liquefied gas concentration level. When liquefied gas detector 2 detects a liquefied gas leak, it sends a signal to controller host 6. Controller host 6 determines the liquefied gas concentration level based on the received signal, and then controls indicator light 302, alarm 8, and explosion-proof fan 1 to take corresponding level actions to ventilate the workshop. When controller host 6 or when workshop ventilation is required, explosion-proof switch 7 can be used to control explosion-proof fan 1 for ventilation.
