Description

Technical Field

[0001] The invention relates to the technical field of hydrogeology, in particular to an automatic collection device for escaping gas from an aquifer. Background Art

[0002] Springs, rivers, and geothermal hot springs in nature are all discharge points of groundwater in aquifers, and the bottom of spring pools, riverbeds, and hot springs generally have gas escaping, which is characterized by unfixed escaping points, uncertain gas composition, uncertain escaping time, small escaping amount, and slow escaping speed. These gases are important supporting indicators for studying the recharge, runoff, discharge, formation, and evolution of groundwater in aquifers, which requires accurate collection of gases escaping from the bottom of the water and determination of the chemical composition of the gases. However, due to technical reasons, we have not been able to collect the gas escaping from the aquifer. The present invention solves the bottleneck problem of the difficulty in collecting escaping gas from the aquifer.

[0003] Patent No. 2012205490380 discloses a device for collecting gas released from bottom mud of water. Although the device can collect bubbles escaping from the bottom of water, it has the following problems:

[0004] First, the device is always floating on the water surface when working and is not in contact with the bottom of the pool. Therefore, when working, it will shift from the original gas collection position under the influence of water flow and wind force. Especially at times when the gas escapes slowly and the time for collecting the gas is long, once the position shifts, it cannot face the position where the gas is gushing out and cannot collect the gas.

[0005] Second, the device has no power device and cannot move autonomously in the water. When in use, it is necessary to manually row a boat to place the device to the location where the gas escapes. Each transfer also needs to be done manually, which is inconvenient to use. Summary of the invention

[0006] In view of the above problems, the present invention provides an automatic collection device for escaping gas in an aquifer, which can not only avoid position displacement under the action of water flow and wind, but also move autonomously in the water without manual transfer, and is easy to use.

[0084] Furthermore, if Figure 1 , Figure 3 and Figure 4As shown, the main box body 1 is provided with a floating plate 9 on its exterior, and the web 311 is located above the propeller 4, and the floating plate 9 is provided with a fourth avoidance hole for accommodating the first guide column 21. As a specific implementation, in this embodiment, two first guide seats 11 are provided at the four corners of the main box body 1, and the two first guide seats 11 located at the same corner are respectively located at the upper and lower ends of the main box body 1, and the floating plate 9 is located between the upper first guide seat 11 and the lower first guide seat 11.

[0085] When working,

[0086] First, install the air storage cylinder 711 in the mounting seat, and make the first push plate 7142 press against the first pressure sensor 72. Then open the solenoid valve 8 and push the large piston 713 to the left until the left side of the large piston 713 presses against the bottom surface of the air storage cylinder 711. Fig.16 The state shown in FIG. 8 is then closed by the electromagnetic valve 8. Repeat the above operation to install all the gas storage cylinders 711 in place.

[0087] Second, the device is put into water as a whole. At this time, the main box body 1 will float on the water surface, and the floating plate 9 can prevent the main box body 1 from tilting.

[0088] Third, the driving motor 35 is activated, and the upper cover 2, the guide column and the air collecting hood 5 move downward as a whole until the counterweight block 22 is completely sunk to the bottom of the pool. At this time, the position of the entire device in the water is fixed and will not move with the water flow and wind force.

[0089] Fourth, open one of the solenoid valves 8.

[0090] 4.1 If gas escapes from the position covered by the gas collecting hood 5, the gas will enter the air inlet 7121 of the transition connector 712 through the pipeline. Fig.16As shown, since the left side of the large piston 713 is pressed against the bottom surface of the gas cylinder 711, the small piston 714 is separated from the bottom surface of the gas cylinder 711, so the large piston 713, the small piston 714 and the bottom surface of the gas cylinder 711 will form an air cavity 717 together. Therefore, the gas in the air inlet 7121 will enter the air cavity 717. As the gas continues to escape, the pressure in the air cavity 717 increases. When the pressure in the air cavity 717 increases to a certain extent, the small piston 714 will move to the right under the action of the gas pressure to overcome the action of the spring 715. When the small piston 714 moves to the right, the first push plate 7142 will be separated from the first pressure sensor 72 under the push of the first connecting rod 7141. At this time, the first pressure sensor 72 cannot detect the pressure signal, which means that there is gas escaping at this position and can continue to collect at this position.

[0091] 4.2 If the pressure value fed back by the first pressure sensor 72 does not change after staying at the position for a certain period of time, for example, 30 minutes, it means that there is no gas escaping at the position. Then close the solenoid valve 8, start the drive motor 35, drive the counterweight 22 to rise, and make the counterweight 22 separate from the bottom of the pool. Then start the propeller 4 to move the device as a whole to the next collection position, and repeat the operations from the third step to the fourth step until the position where the gas escapes is found.

[0092] Fifth, after finding the gas escape location, as the gas continues to escape, Fig.16 As shown, since the small piston 714 will drive the large piston 713 to move to the right when it moves to the right, when the large piston 713 moves to the right together with the small piston 714, the space used to accommodate the gas suddenly becomes larger, and the gas pressure in the space will drop instantly. At this time, the gas pressure acting on the small piston 714 is not enough to resist the force of the spring 715, and the small piston 714 will move to the left under the action of the spring 715 until the first push plate 7142 is pressed against the first pressure sensor 72 again. Since the large piston 713 and the first connecting rod 7141 are in a sliding connection, the friction force between the first connecting rod 7141 and the large piston 713 alone is not enough to drive the large piston 713 to move to the left together with the small piston 714. Therefore, when the small piston 714 moves to the left under the action of the spring 715, the position of the large piston 713 remains unchanged. Fig.12 and Fig.13As shown in FIG. 1 , when the first push plate 7142 is pressed against the first pressure sensor 72, the air inlet 7121 of the transition connector 712 is in an open state. Therefore, the gas escaping from the bottom of the pool will enter the gas storage cylinder 711 through the air inlet 7121, and the large piston 713 will continue to move to the right as the gas in the gas storage cylinder 711 increases, until the second push plate 7133 is pressed against the second pressure sensor 73, that is, Fig.17 As the gas in the gas cylinder 711 increases, the pressure value detected by the second pressure sensor 73 will also increase continuously. When the set pressure value is reached, the solenoid valve 8 corresponding to the gas cylinder 711 is closed, and the solenoid valve 8 of the next gas cylinder 711 is opened to continue collecting gas until all the gas cylinders 711 are full of gas.

[0093] Sixth, start the drive motor 35 to drive the counterweight 22 to rise and separate the counterweight 22 from the bottom of the pool. Then start the propeller 4, move the entire device to the shore, and remove the gas storage assembly 71. When the gas storage assembly 71 is removed, the small piston 714 will be instantly pressed against the bottom surface of the gas cylinder 711 under the force of the spring 715, and the air inlet 7121 will be blocked to prevent gas leakage. At this time, if the gas pressure in the gas cylinder 711 is relatively large, after removing the gas storage assembly 71, the large piston 713 will continue to move to the right under the action of the gas pressure until it rests on the stop cover 716.
