DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] In the embodiment of the present invention, please refer to Figure 1 and Figure 2 A multifunctional underground pipe well monitoring instrument comprises a monitoring instrument body 1, wherein the monitoring instrument body 1 comprises a box body 101, a handle 102 is rotatably mounted on one end of the box body 101, a storage groove 111 is provided on one side of the bottom of the box body 101, and a lowering detection component 2 is connected to the inner wall of the storage groove 111;

[0028] See also Figure 3 and Figure 4 The lowering detection component 2 includes a shell 201, and a number of sensors are fixedly installed inside the shell 201. A shift component is arranged in the middle of the shell 201. The shift component includes an air supply sleeve 208, and a supply fan 209 is fixedly installed in the middle of the inner wall of the air supply sleeve 208. The present application arranges a shift component in the middle of the shell 201 of the detection component, and the reaction force generated by the airflow blown by the supply fan 209 promotes the overall deflection and displacement of the lowering detection component 2, so as to facilitate the lowering detection component 2 to enter the branched pipe wells in different directions, so as to realize accurate monitoring of various positions of the underground pipe wells.

[0029] To avoid air flow dispersion, an air guide ring 210 is fixedly connected to the bottom of the inner wall of the air supply sleeve 208. The inner wall of the air guide ring 210 is tilted toward the middle, so that the direction of the delivered air flow is more concentrated, and the direction of the pushing force received by the lowered detection component 2 is stable.

[0030] To facilitate the movement of the lowering detection component 2 in the pipe shaft, a shift roller 207 is rotatably installed at one end of the bottom of the shell 201 away from the connecting line 105, and an anti-slip pad is fixedly connected to the outer wall of the shift roller 207. The rotation of the shift roller 207 drives the lowering detection component 2 to move as a whole, so that the device can be operated to different locations in the pipe shaft for sampling and detection operations.

[0031] In order to realize multifunctional monitoring of underground pipe wells, several sensors include a water immersion sensor 202, a combustible gas sensor 206, a temperature sensor 211 and a humidity sensor.

[0032] The water immersion sensor 202 is embedded in the inner wall of the shell 201 at one end away from the connecting line 105, and its sensing end passes through the shell 201 and extends to the outside of the end of the shell 201, so that the bottom of the lowering detection component 2 can first contact the water body in the pipe well during the lowering movement, thereby realizing the detection of the water body in the pipe well.

[0033] See also Figure 4 A combustible gas sensor 206 is arranged on one side of the water immersion sensor 202. In order to realize the pumping and sampling of the gas in the pipe well, an air inlet cavity is arranged on the top of the inner wall of the shell 201. A plurality of air inlets 203 are provided on the top and side walls of the air inlet cavity, that is, the plurality of air inlets 203 are respectively located at the end and the top of the shell 201, so that the sampling positions are dispersed, which is conducive to improving the detection accuracy. A sampling fan 204 is fixedly installed in the middle of the inner wall of the air inlet cavity, and an exhaust pipe 205 is fixedly connected to one end of the air inlet cavity. One end of the exhaust pipe 205 is fixedly connected to the air inlet 203 of the combustible gas sensor 206. By designing a sampling fan 204 in the air inlet cavity, the suction force of the external gas is improved, and it is convenient to transport the gas to the combustible gas sensor 206 in a centralized manner.

[0034] See also Figure 2 A partition cover plate 107 is fixedly connected to the middle of the box body 101. In order to realize the lowering control and winding operation of the lowering detection component 2, a winding component is arranged inside the box body 101. One end of the shell body 201 is fixedly connected to the winding component through a connecting line 105. The winding component is located inside the partition cover plate 107. The winding component includes a winding motor. The output end of the winding motor is fixedly connected to the winding roller 104. The outer wall of the winding roller 104 is wrapped with a connecting line 105. One end of the connecting line 105 is fixedly connected to the shell body 201 of the lowering detection component 2, and the other end is fixedly connected to the middle part of the winding roller 104. In order to facilitate the connection and movement of the connecting line 105, a through hole for the connecting line 105 to pass through is opened in the middle of the storage groove 111, and the inner wall of the through hole is set to an arc surface to reduce friction damage to the connecting line 105.

[0035] In order to remove the sludge impurities attached to the connecting line 105, a cleaning sleeve 106 is fixedly connected to one side of the through hole, and a friction cleaning pad is fixedly connected to the middle of the inner wall of the cleaning sleeve 106. During the lifting, lowering and winding movement of the connecting line 105, the friction of the friction cleaning pad on the connecting line 105 is used to clean the connecting line 105.

[0036] See also Figure 2 In order to adjust the horizontal position of the lower detection component during the lower process, a direction adjustment component 3 is provided below the winding component of the present application. The direction adjustment component 3 includes a linear motor 301. The output end of the linear motor 301 is fixedly connected to a direction adjustment motor 302. Figure 5 The output end of the adjustment motor 302 is fixedly connected to a hanging rod 303, and the bottom of the adjustment rod 303 is fixedly connected to a sliding guide groove 304. The inner wall of the sliding guide groove 304 is slidably connected to a push rod 305, and one end of the push rod 305 is rotatably connected to a supporting roller 307. A supporting groove is opened in the middle of the supporting roller 307, and the width of the supporting groove is consistent with the diameter of the connecting line 105. The present application uses the supporting groove on the supporting roller 307 to limit the connecting line 105, and pushes the supporting roller 307 to shift by sliding the push rod 305, thereby pushing the connecting line 105 to shift horizontally, and cooperates with the adjustment motor 302 to drive the sliding guide groove 304 and the push rod 305 to rotate, so as to realize the adjustment of the horizontal position and direction of the lower detection component.

[0037] In order to improve the stability of the push rod 305 during sliding in the sliding guide groove 304, limiting slide grooves 306 are provided on both sides of the outer wall of the push rod 305, and limiting sliders are fixedly connected to both sides of the inner wall of the sliding guide rail, and the limiting slide grooves 306 are slidably connected to the limiting slider.

[0038] See also Figure 2 In order to store the sliding guide groove 304 and the push rod 305 when not in use, a placement groove 110 is fixedly connected to the other side of the bottom of the box body 101. The sliding guide groove 304 and the push rod 305 are driven by the linear motor 301 to move up and down, so that they enter the placement groove 110 for storage.

[0039] See also Figure 6 In order to realize automatic adjustment of the position of the push rod 305, a driving motor is fixedly installed at one end of the push rod 305, and a driving gear 308 is fixedly connected to the output end of the driving motor. A tooth groove is opened on the inner wall of the sliding guide groove 304, and the driving gear 308 is meshed with the tooth groove.

[0040] See also Figure 2In order to cool down and dissipate heat for the components inside the box 101 and extend the continuous working time of the device, an operation panel 103 is fixedly installed on one side of the top of the box 101, ventilation slots are opened on both sides of the box 101, and a filter 109 is fixedly connected to the inner wall of the ventilation slot, and cooling fans 108 are fixedly installed on both sides of the inner wall of the box 101.

[0041] When the present invention is used, Figure 1 As shown, the device is moved to the top of the pipe well to be monitored by lifting the handle 102, such as Figure 2 As shown, the monitoring assembly is separated from the storage tank 111 and removed, so that it falls naturally under the action of gravity, and then the linear motor 301 is started, as shown in FIG. Figure 5 As shown, the hook rod 303 is driven to move downward, so that the sliding guide rail moves out of the receiving groove, and then the adjustment motor 302 (as shown in FIG. Figure 2 As shown in FIG. 1 ) drives the sliding guide rail to rotate, and the driving motor starts to drive the driving gear 308 (as shown in FIG. Figure 6 As shown in the figure), turn the push rod to push out. Figure 5 As shown, the supporting groove on the supporting roller 307 contacts and limits the connection line 105, and then the adjustment motor 302 drives the hook rod 303 to rotate as a whole, driving the sliding guide rail and the push rod 305 to rotate, thereby pushing the connection line 105 to move horizontally, thereby realizing the horizontal displacement adjustment of the lowered monitoring component;

[0042] Then the winding motor is started to drive the winding roller 104 to rotate, and the monitoring component is lowered into the pipe well. The temperature sensor 211 and humidity sensor thereon detect the temperature and humidity and other parameters in the pipe well. During the lowering process, when there is liquid leakage in the pipe well, the water immersion sensor 202 is located at the end far away from the connecting line 105, and will first contact the liquid, and then detect and judge whether there is water at the detection position. At this time, other sensors can be turned off to prevent any influence. The specific sensor to be used depends on the monitoring needs. When the combustible gas sensor 206 is used, the sampling fan 204 is started, and air is sucked and sampled through the air inlet 203, and then sent into the combustible gas sensor 206 through the exhaust pipe 205;

[0043] When it is necessary to monitor the horizontal bifurcated pipe well, the air supply fan 209 is started to supply air, and the reaction force of the airflow is used to drive the lowered monitoring component to shift laterally as a whole and fall into the bifurcated pipe well. The shift roller 207 is then started to drive the lowered monitoring component to move as a whole in the bifurcated pipe well, so as to reach a suitable sampling monitoring position and realize a fully accurate detection of the overall state of the pipe well.

[0044] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
