The following is a brief description of the operation of the precipitation device 100 for underground construction:

When the precipitation device 100 for underground building construction is used, the precipitation device 100 for underground building construction is moved to a proper position, then, the first driving mechanism 21 drives the water pumping head 22 to move and drop to a designated position, for example, the first motor 214 drives the upright post 211 to drive the first telescopic arm 212, the second telescopic arm 213 and the water pumping head 22 to rotate, the first telescopic arm 212 stretches and contracts to drive the second telescopic arm 213 and the water pumping head 22 to transversely move, and the second telescopic arm 213 stretches and contracts to drive the lower part of the water pumping head 22 to a proper position.

Next, the water pump 23 is started, the groundwater is pumped into the filtering tank 11 through the water pumping head 22 and the first pipeline 231, and in the process of pumping the groundwater, the sediment mixed in the groundwater is filtered once by the filtering mechanism 221 of the water pumping head 22, and in the process of pumping the water, the cleaning brush 2212 sweeps the periphery of the filtering cover 2211 in real time under the action of the spiral rod 2214, so as to prevent the sediment from blocking the filtering cover 2211. And, the driving unit 4 drives the filter cartridge 12 to rotate, the filter cartridge 12 performs secondary filtration on sediment in the groundwater, the groundwater after secondary filtration is pumped and discharged to a designated position from the water purifying cavity 1111 under the action of the water pump 23 via the second pipeline 232, and the sediment filtered after secondary filtration falls onto the bearing component 321 in the slag discharging chamber 112 through the filter cartridge 12.

The bearing assembly 321 gradually moves toward the bottom of the vehicle body 1 and gradually compresses the first elastic assembly 322 as the weight of the silt increases. When the bump 32111 of the carrier 321 moves to the trigger block 3311 of the trigger 331, the trigger 331 is gradually driven to move toward the bottom of the vehicle body 1 along with the increase of the silt weight, and the limiting member 3321 gradually moves away from the trigger 331, so that the limiting arm 33212 of the limiting member 3321 gradually disengages from the limiting block 311 of the plugging plate 31, and the second elastic component 3322 is gradually compressed.

When the weight of the sediment on the bearing assembly 321 reaches the preset weight value, the limiting arm 33212 of the limiting piece 3321 is separated from the limiting piece 311 of the plugging plate 31 under the pushing of the trigger piece 331, and the plugging plate 31 moves into the filter box 11 under the action of gravity to seal and isolate the filter chamber 111 from the slag discharge chamber 112. At this time, the precipitation device 100 for underground construction can continue the pumping operation, and the door 1122 at the slag hole 1121 can be opened at this time to clean the silt in the slag chamber 112. When the removal of silt from the tapping chamber 112 is completed, the door 1122 is closed, causing the door 1122 to reseal the tap hole 1121.

Then, the second driving mechanism 51 of the lifting unit 5 drives the clamping mechanism 52 to move toward the plugging plate 31, and when the clamping mechanism 52 moves to the clamped portion 312 of the plugging plate 31, the clamping mechanism 52 is driven by the second driving mechanism 51 to move downward, and the two clamping arms 523 of the clamping mechanism 52 move back to back under the action of the arrow-shaped clamped portion 312, at this time, the tension spring 525 is stretched, and the guide post 522 slides relative to the substrate 521. When the hook 5231 of the clip arms 523 passes over the clamped portion 312, the two clip arms 523 move toward each other by the tension spring 525, and the hook 5231 is fastened to the bottom of the arrow-shaped clamped portion 312.

Then, the second driving mechanism 51 of the lifting unit 5 drives the clamping mechanism 52 to move back to the filter box 11 to pull the plugging plate 31 back to the filter box 11, so that the plugging plate 31 releases the sealing isolation of the filter chamber 111 and the slag tap chamber 112. In the process of moving the plugging plate 31 back to the filter box 11, the limiting piece 3321 is controlled to move back to the trigger piece 331 so as to avoid the limiting arm 33212 from blocking the plugging plate 31 to move upwards. When the height of the limiting block 311 of the blocking plate 31 is higher than the limiting arm 33212, the control of the limiting piece 3321 can be released, so that the limiting piece 3321 moves toward the trigger piece 331 under the action of the second elastic component 3322 until the limiting piece 3321 is at the initial position.

As the second driving mechanism 51 of the lifting unit 5 drives the clamping mechanism 52 to move back to the filter box 11, when the top end of the guide post 522 of the clamping mechanism 52 contacts with the vehicle body 1, the vehicle body 1 limits the guide post 522 to move upwards, and the substrate 521 continues to move downwards driven by the second driving mechanism 51, at this time, the substrate 521 slides relatively with the guide post 522, and as the substrate 521 moves upwards, the two clamping arms 523 move away from each other, the clamping of the clamped portion 312 of the plugging plate 31 is released, so that the plugging plate 31 moves downwards again under the action of gravity until the bottom of the limiting block 311 contacts with the limiting arm 33212, so as to limit the plugging plate 31 to move downwards.

In addition, a position sensor and an alarm can be arranged in the sealing cavity 3210, so that when the sealing plate 31 seals and isolates the filtering chamber 111 and the slag discharging chamber 112, the position sensor sends a detection signal to the controller, so that the controller controls the alarm to alarm, and a worker is reminded to clean the sediment in the slag discharging chamber 112.

In summary, it can be seen that, because the pumping unit 2 can drive the pumping head 22 through the first driving mechanism 21 to move in the three-dimensional space, when in operation, the precipitation device 100 for underground construction can be parked to a proper position, and then the pumping head 22 is driven by the first driving mechanism 21 to be lowered to the operation position for pumping operation, the design makes the precipitation device 100 for underground construction adaptable to various complicated ground conditions, improving the flexibility, safety and reliability of operation, while the groundwater pumped by the pumping unit 2 is filtered once through the filtering mechanism 221 in the pumping head 22, then enters the filtering box 11 for secondary filtration by the filtering cylinder 12, so as to further leave silt in the groundwater in the filtering cylinder 12, and the filtered groundwater waits for cleaning under the action of the filtering cylinder 12, and is pumped and discharged to a designated position by the water pump 23 through the water outlet 1113 of the water purifying cavity 1111, the silt in the groundwater can be further filtered by the water pump 23, thereby prolonging the service life of the water pump 23. In addition, by arranging the blocking unit 3, when sediment in the slag chamber 112 needs to be removed, the blocking plate 31 is controlled to seal and isolate the filtering chamber 111 from the slag chamber 112, so that when sediment in the slag chamber 112 is removed, the water pump 23 can continue to perform reliable water pumping and filtering operation through the filtering chamber 111, and the slag chamber 112 can synchronously perform sediment cleaning, so that the precipitation device 100 for underground building construction does not need to stop working in the sediment cleaning process, the construction efficiency is improved, and when sediment in the slag chamber 112 is cleaned, the blocking plate 31 is reset, so that sediment in the filter cartridge 12 can continue to flow to the slag chamber 112, the filter cartridge 12 is not blocked, and the filtering effect of the filter cartridge 12 is ensured.

Finally, it should be emphasized that the foregoing description is merely illustrative of the preferred embodiments of the utility model, and that various changes and modifications can be made by those skilled in the art without departing from the spirit and principles of the utility model, and any such modifications, equivalents, improvements, etc. are intended to be included within the scope of the utility model.
