Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of detection devices, in particular to an underground valve well laser methane gas detection structure. Background Art
[0002] High-pressure pipelines for urban gas are generally buried on municipal roads or at the junction of urban areas and suburbs. Due to the precious land resources in cities, according to the planning of urban roads, valves on natural gas pipelines are generally set in the form of underground valve wells instead of ground valve chambers to save precious land resources. The underground valve well is a closed and limited space. After long-term operation of pipelines, valves and other facilities in the gas valve well, in an unventilated and humid environment, the valve body, flange and other parts may cause local gas leakage due to corrosion, expansion and contraction, etc. Uneven foundation settlement will also cause local leakage of connectors. In addition, under poor ventilation conditions, gas is prone to accumulation. When the concentration reaches the explosion concentration limit of 5%-15%, gas explosion accidents may occur due to open flames, friction between tools, and electrostatic induction. There are many industrial areas and residential areas around urban gas high-pressure pipelines, and pipeline explosions will cause serious casualties and property losses. In addition, the valve well is low in terrain. In case of extreme weather or water seepage due to long-term operation of the valve well, water accumulation is likely to occur, and valves and pipelines are prone to corrosion and leakage due to water flooding. Utility Model Content
[0003] The utility model aims to provide an underground valve well laser methane gas detection structure to solve the problems raised in the above background technology.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a laser methane gas detection structure for an underground valve well, comprising a top box and a sleeve, a first cavity is opened at the top end of the interior of the top box, a gas detector is fixed in the middle of the interior of the first cavity, a second cavity is opened at the bottom end of the interior of the top box, a radar water level meter is fixed at one end of the interior of the second cavity, a sleeve is connected to the outer bottom surface of the top box, a sleeve rod is provided in the middle of the interior of the sleeve, and an inner rod is inserted into the interior of the sleeve rod.
[0005] When using an underground valve well laser methane gas detection structure in the technical solution, the staff needs to first install the utility model and carry the utility model to the valve well position to be installed. After arriving at the position, the staff adjusts the extension distance of the sleeve rod according to the depth of the bottom surface of the valve well and the position to be detected. The specific adjustment operation is that the staff turns to open the box door. After the box door is opened, the staff holds the handle and turns it, and the rotational force applied to the handle will be synchronized to the inner rod, and the inner rod will rotate inside the sleeve rod. At this time, the thread provided on the surface of the inner rod will engage with the thread provided on the inner surface of the sleeve rod. The engagement of the thread causes the sleeve rod to move on the surface of the inner rod, and the moving sleeve rod will push the pointed head connected at one end to move together. After the adjustment is completed, the staff will place the utility model vertically, then apply pressure to the utility model and use the pointed head to insert into the soil on the bottom surface of the valve well to vertically fix the utility model. After the utility model is vertically fixed and installed, the staff also needs to use the terminal equipment to set data for the processor in the processing device body, set the operating interval of the fan and the gas detection content of the gas detector The value of the quantity and the value of the water level detected by the radar water level gauge can be set to the normal operation of the utility model. During normal operation, the fan will rotate, and after the fan rotates, a flow air duct will be formed in the first cavity. The external gas will enter the first cavity through the air inlet and be detected by the gas detector. After detection, it will be discharged through the air outlet, accelerating the air flow underground so that the gas detector inside the top box can detect the gas in the non-flowing position, and detect the content of the gas contained in the gas. When the gas detector detects that the gas contained in the gas is higher than the set value, the gas detector will send an electrical signal to the processor in the processing device body, and then the processor will process the signal and send the signal to the terminal through the transmitter for the staff to know, and then the staff will go to the valve well here for maintenance. The radar water level gauge will monitor the water level in the valve well. When the water level is higher than the set value, the radar water level gauge will send an electrical signal to the processor in the processing device body, and then the processor will process the signal and send the signal to the terminal through the transmitter for the staff to know, and then the staff will go to the valve well here for maintenance.
[0006] Preferably, the surface of the inner rod and the inner surface of the sleeve rod are both provided with threads and mesh with each other. Through the cooperation between the inner rod and the sleeve rod, since both the surface and the inner surface of the inner rod are provided with threads, when the inner rod rotates, the threads on its surface will mesh with the threads on the inner surface of the sleeve rod, and the sleeve rod will move on the surface of the inner rod due to the meshing of the threads, thus achieving the effect of indirectly controlling the installation and use height position of the top box by the meshing of the threads.
[0007] Preferably, a rotating handle is fixed to the top of the inner rod, and the rotating handle is arranged in the middle of the second cavity. The arrangement of the rotating handle makes it convenient for the staff to apply rotating force to the inner rod, and provides a force application point.
[0008] Preferably, the outer sides of the sleeve rod are connected with sliding sleeves, the inner sides of the sliding sleeves are inserted with sliding rods, and the sliding rods are fixed to the inner sides of the sleeve. Through the cooperation of the sliding sleeves and the sliding rods, the inner rod is limited when the sleeve rod is threadedly engaged and moved, so as to prevent the sleeve rod from rotating together with the inner rod.
[0009] Preferably, the outer bottom end of the sleeve rod is connected with a pointed head. By providing the pointed head, the sleeve rod can be inserted into the soil on the bottom surface of the valve well, achieving the effect of inserting and fixing the utility model to be placed vertically.
[0010] Preferably, an air inlet is provided on one side of the first cavity, an air outlet is provided on the other side of the first cavity, and a fan is fixed on the surface of the air outlet. Through the cooperation of the air inlet, the air outlet and the fan, the gas in the valve well can actively enter the interior of the top box and be detected by the gas detector, thereby achieving the effect of detecting the gas content of the gas in the non-flowing position in the valve well.
[0011] Preferably, a processing device body is provided at the other end of the second cavity. The processing device body is provided with a battery, a processor, a transmitter and other structures. The battery can supply power to the device in the utility model for endurance use, and the processor can process the information transmitted to it by the gas detector and the radar water level gauge and can control the operation of the fan, and the transmitter can receive and send electrical signals.
