技术领域technical field
本实用新型具体涉及燃气检测技术领域,具体是一种天然气管道泄漏检测器。The utility model specifically relates to the technical field of gas detection, in particular to a natural gas pipeline leakage detector.
背景技术Background technique
随着燃气在生活中的重要性逐渐提高,从而提高了人们对燃气管道安全及环保的日益重视,而用来输送天然气的管道极为重要,需要定期进行检测管道是否出现泄漏。传统的天然气泄漏检测采用的是肥皂水喷淋法,通过观看喷淋在管道上的肥皂水是否出现起泡的情况来判断是否泄漏。As the importance of gas in life gradually increases, people pay more and more attention to the safety and environmental protection of gas pipelines, and the pipelines used to transport natural gas are extremely important, and it is necessary to regularly detect whether the pipelines are leaking. Traditional natural gas leak detection uses the soapy water spray method, and it is judged whether there is a leak by observing whether the soapy water sprayed on the pipeline bubbles.
中国专利公告号CN 215951133 U公开了一种天然气管道泄漏检测装置,包括:管道主体;固定环,所述固定环均固定安装于所述管道主体的两侧;固定箱,所述固定箱固定安装于所述固定环的顶部;控制结构,所述控制结构固定安装于所述固定箱的内部,所述控制结构包括滑槽,所述滑槽的内部滑动连接有滑块,滑块的顶部且为与滑槽的内部设置有弹簧,滑块的左侧固定连接有气囊,气囊的顶部固定安装有触碰头,固定箱内部的顶部固定安装有警报开关。Chinese Patent Announcement No. CN 215951133 U discloses a natural gas pipeline leakage detection device, comprising: a pipeline main body; a fixed ring, the fixed rings are fixedly installed on both sides of the pipeline main body; a fixed box, the fixed box is fixedly installed On the top of the fixed ring; control structure, the control structure is fixedly installed inside the fixed box, the control structure includes a chute, the inside of the chute is slidably connected with a slider, the top of the slider and In order to be provided with a spring with the inside of the chute, the left side of the slide block is fixedly connected with an air bag, the top of the air bag is fixedly equipped with a touch head, and the top of the fixed box inside is fixedly equipped with an alarm switch.
该天然气管道泄漏检测装置是将检测装置直接固定在管道的接头处进行实时监测,但是由于管路铺设距离较长,管接头较多,就需要诸多的检测装置进行安装和实时监测,这就极大的提高了燃气公司的安装成本,按照城市的管路泄漏情况分析来看,管路的泄漏主要是由三方破坏所造成,例如地面沉降压裂、机动车撞坏或者其它施工设备撞坏所导致;因此在每个管道接头上安装一个泄漏检测装置,显然是没有必要的,并且成本和后期维护是极高的。The natural gas pipeline leakage detection device is to directly fix the detection device at the joint of the pipeline for real-time monitoring, but due to the long laying distance of the pipeline and the large number of pipe joints, many detection devices are required for installation and real-time monitoring, which is very difficult. The installation cost of the gas company has been greatly increased. According to the analysis of the pipeline leakage situation in the city, the pipeline leakage is mainly caused by three-party damage, such as ground subsidence and fracturing, motor vehicle crashes or other construction equipment crashes. Therefore, it is obviously unnecessary to install a leak detection device on each pipe joint, and the cost and later maintenance are extremely high.
中国专利公告号CN 208295561 U公开了一种天然气管道泄漏检测装置,其结构包括开关按键、主体、连接导线、声音报警器、控制面板、连接件、感应器、探头、调节按钮、指示灯、灯光报警器、显示屏,开关按键嵌入安装于控制面板的正表面,本实用新型一种天然气管道泄漏检测装置,结构上设有灯光报警器,嵌入安装于主体顶端,当感应器与探头感应到天然气后,使得控制器控制步进电机带动锥齿轮转动,使得配合齿轮旋转,同时从动齿轮转动,从而使得安装板与接触片跟随一起旋转,通过改变接触片与电阻线圈接触的位置,用以改变通过报警灯的电流的大小。Chinese patent announcement number CN 208295561 U discloses a natural gas pipeline leakage detection device, its structure includes switch buttons, main body, connecting wires, sound alarm, control panel, connectors, sensors, probes, adjustment buttons, indicator lights, lights Alarm, display screen, and switch buttons are embedded and installed on the front surface of the control panel. The utility model is a natural gas pipeline leakage detection device. Finally, the controller controls the stepper motor to drive the bevel gear to rotate, so that the matching gear rotates, and the driven gear rotates at the same time, so that the mounting plate and the contact piece rotate together. By changing the contact position of the contact piece and the resistance coil, it is used to change The magnitude of the current passing through the warning light.
上述专利中的检测装置是一种手持式检测仪,这种检测装置在对室外管道进行检测的时候,其精准度受管道的泄漏面积和风力影响,一旦风力大,将泄漏的燃气吹散,该检测装置难以对天然气的泄漏进行监测到。The detection device in the above patent is a hand-held detector. When this detection device detects outdoor pipelines, its accuracy is affected by the leakage area of the pipeline and the wind force. Once the wind force is strong, the leaked gas will be blown away. It is difficult for the detection device to monitor the leakage of natural gas.
为此我们提供一种手持的天然气管道泄漏监测装置,该检测装置不但携带方便,而且在对室外管道进行泄漏监测的时候不受风力影响,并且具有较好的精准性和灵敏性。To this end, we provide a hand-held natural gas pipeline leakage monitoring device, which is not only easy to carry, but also not affected by wind force when monitoring outdoor pipeline leakage, and has better accuracy and sensitivity.
