Description

Technical Field

[0001] The utility model relates to the field of gas detection, in particular to an underground valve well combustible gas monitor. Background Art

[0002] When in the natural gas valve well, the pipeline and valve connections are prone to leakage and accumulation, which may cause danger in the future. At this time, the combustible gas monitor and alarm device can remind people to inspect the valve well;

[0003] After searching, a Chinese patent disclosed a valve well monitor (publication number CN 211402231 U). This patented technology instrument is connected to the backend server through an NB-I0T module, and uploads data such as the concentration of the detected gas, water level, its own battery power, and network signals, so as to realize real-time monitoring of the gas situation in the valve well, the water level in the valve well, its own battery power, and network signals. However, in the technical solution of the above patent document, the valve well environment is relatively humid, which can easily corrode the internal electronic equipment, causing internal circuit short circuit damage, thus affecting the service life.

[0004] Therefore, an underground valve well combustible gas monitor is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide an underground valve well combustible gas monitor in order to solve the above-mentioned problem, thereby improving the problem that the valve well environment is relatively humid, which easily corrodes the internal electronic equipment, causing internal circuit short circuit damage and shortening the service life.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions.

Both of the condensation plates are installed at an angle on the inner wall of the installation box. The condensation drainage assembly can be used to guide and drain the accumulated water in the outer shell, thereby reducing the residual moisture in the outer shell. At the same time, the inclined shape forms a certain barrier to the water vapor entering the outer shell, thereby reducing the entry of water vapor into the outer shell.

[0008] Preferably, one side end of each of the two condensation plates is fixedly connected with a side baffle, and both of the side baffles are parallel to the inner wall of the installation box. The side baffles can block the rising water vapor, making it convenient for the water vapor to condense and drip at the lower end of the condensation plate.

[0009] Preferably, a plurality of main condensation cones are fixedly connected to the lower ends of the two condensation plates, and the plurality of main condensation cones are dispersedly arranged on the lower side of the condensation plates. The main condensation cones can facilitate condensation of water vapor on the surface of the main condensation cones, thereby improving condensation dripping efficiency.

[0010] Preferably, multiple auxiliary condensation cones are fixedly connected to the surfaces of the multiple main condensation cones, and the multiple auxiliary condensation cones are all cone-shaped. The auxiliary condensation cones can make the water condense more finely and increase the surface area to facilitate dripping.

[0011] Preferably, the moisture absorption component includes a mounting hole opened at the upper end of the outer shell, the inner wall of the mounting hole is fixedly connected to a sealing ring, and the inner wall of the sealing ring is slidably connected to a water absorption basket.

The water absorption basket can be fixed by the fixed spring sheet and the snap-in hole to prevent skewed installation and poor sealing.

[0013] The beneficial effects of the utility model are:

[0014] 1. When the air entering the shell contains a lot of moisture, the condensation drainage component can be used to facilitate the condensation of moisture and then drip directly to reduce the moisture content entering. The moisture entering the shell can be absorbed to make the internal environment drier and reduce the probability of damage caused by the humid environment inside the shell;

[0015] 2. The main condensation cone can increase the surface area, increase the water condensation and adsorption area, and facilitate the condensation of water vapor. The secondary condensation cone can increase the surface area again, and at the same time make the tip dripping part larger, which makes it easier for water droplets to drip downward after increasing condensation.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] During specific implementation: as shown in Figure 4, an underground valve well combustible gas monitor includes: a mounting frame 1, a side end of the mounting frame 1 is fixedly connected to a shell 2, an inner wall of the shell 2 is fixedly connected to a sensor main control board 3, a side end of the sensor main control board 3 is fixedly connected to an antenna 4, a lower end of the sensor main control board 3 is fixedly connected to a sensor probe 7, the sensor probe 7 and the antenna 4 are fixedly penetrated through the inner wall of the shell 2 and extend outward; a condensation drainage component 5, which is used to facilitate the discharge of water flow in the shell 2 and is arranged on the lower side of the shell 2; a moisture absorption component 6 is used to absorb moisture from the air in the shell 2, so that the moisture absorption component 6 in the shell 2 is dry. The receiving component 6 is arranged on the upper side of the shell 2. When used by this device, the mounting frame 1 can be fixed to the inner wall of the well by bolts, and then the shell 2 is hung. The sensor probe 7 receives the external combustible gas information and converts it into an electrical signal to be transmitted to the sensor main control board 3. The sensor main control board 3 has a battery, an Internet of Things chip and a host information processing part of the sensor. The information is transmitted to the outside through the antenna 4 to increase the transmission signal effect. At this time, the device can realize the detection of the amount of combustible gas in the well. For the staff in this technical field, the sensor main control board 3, the sensor probe 7 and the antenna 4 are all existing technologies and will not be elaborated here.

[0023] like Figure 2 and Figure 3As shown, the condensation drainage assembly 5 includes a mounting box 501 fixedly connected to the lower end of the shell 2, a drainage oblique block 505 is fixedly connected to the lower inner wall of the shell 2, and two condensation plates 502 are fixedly connected to the inner wall of the mounting box 501. The two condensation plates 502 are both installed obliquely on the inner wall of the mounting box 501. When air containing moisture enters the shell 2 from the condensation drainage assembly 5, some moisture in the air condenses on the lower side of the condensation plate 502. At this time, the water drips and is discharged through the inclination angle of the condensation plate 502. One side end of the two condensation plates 502 is fixedly connected to a side baffle 506. The two side baffles 506 are both connected to the inner wall of the mounting box 501. Parallel, some moisture in the air can be blocked by the side baffle plate 506 to increase the condensation effect of moisture in the air, and multiple main condensation cones 503 are fixedly connected at the lower ends of the two condensation plates 502. The multiple main condensation cones 503 are dispersedly arranged on the lower side of the condensation plate 502. The main condensation cones 503 can increase the surface area, increase the moisture condensation adsorption area, and facilitate the condensation of water vapor. Multiple main condensation cones 503 are fixedly connected to the surface of the multiple secondary condensation cones 504, and the multiple secondary condensation cones 504 are all cones. The secondary condensation cones 504 increase the surface area again and make the tip dripping part more. After the condensation is increased, it is convenient for the water droplets to drip downwards.

[0024] like Figure 1 and Figure 4 As shown, the moisture absorption component 6 includes a mounting hole 602 opened at the upper end of the shell 2, and a sealing ring 603 is fixedly connected to the inner wall of the mounting hole 602, and a water absorption basket 601 is slidably connected to the inner wall of the sealing ring 603. The water absorption basket 601 has a rubber ball desiccant inside, and the surface of the water absorption basket 601 has holes, so that the desiccant in the water absorption basket 601 can contact with the air in the shell 2 to absorb moisture, and a positioning plate 604 is fixedly connected to the upper end of the water absorption basket 601, and a snap-in hole 606 is opened at the upper end of the positioning plate 604. A fixed spring sheet 605 is fixedly connected to the upper end of the shell 2, and the fixed spring sheet 605 is movably snap-fitted with the inner wall of the snap-in hole 606. Through the snap-fitting of the fixed spring sheet 605 and the snap-in hole 606, the moisture absorption component 6 can be easily disassembled and the desiccant can be replaced to maintain the water absorption effect.

[0025] When the utility model is in use, when air containing moisture enters the outer shell 2 through the condensation drainage component 5, some moisture in the air condenses on the lower surface of the condensation plate 502, the circumferential surface of the main condensation cone 503 and the auxiliary condensation cone 504. At this time, the water drips and is discharged through the inclination angle of the condensation plate 502. At the same time, the air entering the outer shell 2 will have some moisture. The desiccant in the water absorption basket 601 adsorbs the moisture in the air in the outer shell 2, making the environment in the outer shell 2 drier, reducing the probability of damage to the sensor main control board 3 due to the humid environment in the outer shell 2, and increasing the service life of the device.

[0026] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
