DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. 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.

[0028] Example

[0029] Please refer to Figure 1-4 The embodiment of the utility model provides a water suction device for construction sites, the device comprising: a walking frame 10, and a pumping and drainage mechanism and an air suction pumping mechanism arranged on the walking frame 10;

[0030] The pumping and drainage mechanism includes: a water suction head 21, a sediment separator 22 and a self-priming pump 23. The water suction head 21 is connected to the water inlet of the sediment separator 22 through a water inlet pipeline, and the water outlet of the sediment separator 22 is connected to the water inlet of the self-priming pump 23 through a water outlet pipe 41. The end of the water suction head 21 is arranged close to the ground of the construction site.

[0031] The air suction pumping mechanism includes: an air suction head 31, an air-cement separator 32 and a centrifugal fan 33. The air suction head 31 is connected to the air suction port of the air-cement separator 32 through an air suction pipeline, the exhaust port of the air-cement separator 32 is connected to the air suction port of the centrifugal fan 33 through an air outlet pipeline, and the exhaust port of the centrifugal fan 33 is connected to the air suction head 31 through a return air duct.

[0032] The utility model provides a construction site water suction device. When the water level is deep, the pump drainage mechanism pumps out water by pumping, and the drainage rate is fast. When the water level is lower than the suction depth of the self-priming pump 23, the air suction pumping mechanism uses air suction to remove the residual water, and the water and silt on the construction site are completely removed. The device integrates water pumping and water absorption, and utilizes suction and airflow to suck away the water and silt on the ground and dispose of them in a centralized manner. There is no need to dig drainage ditches and drainage pits to remove water on the construction site, which reduces the excavation workload, shortens the excavation period, and improves the construction progress.

[0033] The utility model provides a water suction device for construction site accumulation. Deep water is drained by pumping, and shallow water is removed by air suction. The accumulation on the construction site contains a large amount of mud and sand, so mud and sand separation is used to prevent mud and sand from getting stuck in the pump and clogging the pipeline. The air-cement separation device can separate mud and water in the air flow, and the circulating air can reduce exhaust to avoid interfering with nearby construction. The device can be moved along with the construction site for operation.

[0034] The whole device is advanced or retreated by the traveling frame 10. During operation, the traveling frame moves forward or backward within a set range, and the accumulated water can be removed in a larger range. The traveling frame 10 can be replaced by a vehicle carrier as a mobile platform. The water tank on the vehicle carrier can replace the water outlet mechanism. After the water tank is filled, it is transported to the discharge point for discharge. The power system of the vehicle carrier provides power energy for the accumulated water suction device, which can replace the cable drum 43 and is suitable for scenes with small drainage volume or no power supply.

[0035] In the pumping and drainage mechanism, the suction head 21 contacts the accumulated water on the ground of the construction site, and the self-priming pump 23 is started. The accumulated water enters the sediment separator 22 from the suction head 21 for sediment separation to prevent the sediment from clogging the pipeline. The suction head 21 is equipped with a filter to prevent small stones in the accumulated water from being sucked into the pipeline. The self-priming pump 23 is a centrifugal self-priming pump 23 or a variable volume self-priming pump 23 with self-priming and exhausting capabilities. It self-primes and discharges the gas in the water inlet pipeline and the sediment separator 22. The self-priming pump 23 can automatically discharge the air in the water inlet pipeline without manually discharging the air in the water inlet pipeline. It is a general term for water pumps with self-exhaust characteristics, including but not limited to plunger pumps, diaphragm pumps, centrifugal self-priming pumps 23, gear pumps, etc.

[0036] In the air suction pumping mechanism, the air suction head 31 is a double-layer jacketed pipe, the inner layer of the pipe is connected to the air suction pipeline, and the outer layer of the pipe is connected to the return air pipeline. Under the suction action of the centrifugal fan 33, air is sucked from the air suction head 31 together with the accumulated water, and enters the air-cement separator 32 through the air suction pipeline. The soil sucked in with the air settles to the bottom of the air-cement separator 32 and is discharged from the mud discharge valve. The accumulated water sucked in with the air settles to the middle of the air-cement. The air flow flows into the air suction port of the centrifugal fan 33 from the top of the air-cement separator 32, flows to the exhaust port after being accelerated by the centrifugal fan 33, and returns to the outer layer of the jacketed pipe of the air suction head 31 through the return air pipeline, forming an air flow circulation; the return air pipeline and the outer jacketed pipe of the air suction head 31 lead the air flow with a small amount of water mist to the air suction port, forming an air flow circulation without blowing outward.

[0037] The sediment separator 22 and the gas-cement separator 32 use centrifugal sedimentation to achieve separation. Centrifugal sedimentation uses the different specific gravities of the components in the fluid mixture and the difference in centrifugal force generated by centrifugal rotation to separate them. The material with a larger specific gravity has a larger gyration radius, while the material with a smaller specific gravity has a smaller gyration radius. The efficiency of separating different materials in the fluid mixture is higher than that of natural gravity sedimentation separation, and it can separate liquids and solids, liquids and liquids, gases and solids, and gases and liquids. The sediment separator 22 of the utility model uses a centrifugal cyclone sedimentation separator for liquids and solids, and also uses an gas-cement separator 32 for gas phase and non-gas phase separation. The sediment separator 22 and the gas-cement separator 32 of the utility model can be replaced by a filter separator, so the sediment separator 22 and the gas-cement separator 32 of the utility model do not specifically refer to centrifugal sedimentation separators.

[0038] The sediment separator 22 and the air-cement separator 32 may adopt a centrifugal separation or a filtering separation method. In the present utility model, the sediment separator 22 and the air-cement separator 32 do not specifically refer to centrifugal sedimentation separators.

[0039] In some feasible embodiments, the pumping and drainage mechanism further includes: a water inlet valve 24, which is disposed on the water inlet pipeline.

[0040] In some feasible embodiments, a sand discharge port of the sand separator 22 is provided with a sand discharge valve 25. The sand discharge valve 25 is provided to discharge the sand accumulated at the bottom of the sand separator 22.

[0041] In some feasible embodiments, the air suction pumping mechanism further includes: an air suction outlet valve 34, which is connected to the water outlet of the air-cement separator 32 through a water outlet pipe 41. The air suction outlet valve 34 is provided to discharge the separated water of the air-cement separator 32.

[0042] In some feasible embodiments, the air suction pumping mechanism further includes: a water level sensor 35, which is disposed on the air-cement separator 32. The water level sensor 35 is used to detect the water level of the air-cement separator 32, including components constituted by ultrasonic ranging detection, water level probe detection, buoyancy switch detection, etc.

[0043] In some feasible modes, the device further includes: a water accumulation sensor 36, which is arranged on the traveling frame 10. The water accumulation sensor 36 is used to detect the water level, including components constituted by ultrasonic ranging detection, water level probe detection, buoyancy switch detection and the like.

[0044] In some feasible embodiments, the device further includes a water outlet mechanism, which includes: a water outlet pipe 41, a water outlet pipe drum 42 and a cable drum 43, the water outlet pipe drum 42 and the cable drum 43 are arranged on the walking frame 10, the water outlet pipe 41 is connected to the water outlet pipe drum 42, and the water outlet pipe drum 42 is connected to the water outlet of the self-priming pump 23 through the water outlet pipe 41. The water outlet pipe drum 42 automatically retracts and releases the water outlet pipe 41 according to the walking position, and the cable drum 43 automatically retracts and releases the cable according to the walking position.

[0045] In some feasible embodiments, the water outlet mechanism further includes a one-way valve 44 , and the one-way valve 44 is disposed on the water outlet pipe 41 .

[0046] In some feasible modes, the device further includes: an air suction mobile frame, which includes: a crossbar 51, a vertical bar 52 and a lifting member 53, wherein both ends of the crossbar 51 are connected to the vertical bar 52 through the lifting member 53, and the ends of the vertical bar 52 are arranged on the traveling frame 10, and the air suction head 31 is installed on the crossbar 51. The lifting member 53 drives the air suction head 31 to move back and forth quickly, so that the air suction head 31 repeatedly contacts with the accumulated water and then separates.

[0047] In some feasible ways, the air suction moving frame also includes: a transverse member 54, which is slidably arranged on the cross bar 51, and the air suction head 31 is installed on the transverse member 54. The transverse member 54 drives the air suction head 31 to move back and forth quickly, so that the air suction head 31 absorbs water in a larger range. Through the coordinated use of the transverse member 54 and the lifting member 53, the air suction head 31 absorbs water in a larger range and repeatedly contacts with the accumulated water before separation, so that the accumulated water becomes small droplets under the action of the air flow and is sucked into the air-cement separator 32 with the air, so as to avoid the accumulated water forming a water column in the suction pipeline and blocking the air inlet channel of the fan.

[0048] Please refer to Figure 1-4 The working process of the construction site water suction device provided by the utility model is as follows:

[0049] When the water accumulation sensor 36 detects that the water level is high, the self-priming pump 23 starts to operate, opens the water inlet valve 24, and closes the air suction outlet valve 34; the pressure in the water suction head 21, the water inlet valve 24, the sediment separator 22 and the pipeline on the inlet side of the self-priming pump 23 decreases, and the accumulated water is sucked into the self-priming pump 23 through the water suction head 21, the water inlet valve 24, and the sediment separator 22 in turn, and after being pressurized by the self-priming pump 23, it is merged into the main drainage pipe through the one-way valve 44 and the outlet pipe 41. When the water inlet valve 24 is opened and the air suction outlet valve 34 is closed, the self-priming pump 23 delivers water from the water inlet valve 24 pipeline; the sediment separator 22 centrifugally settles and separates the sediment sucked in with the water, preventing the sediment from wearing the self-priming pump 23 and clogging the pipeline, and the sediment accumulated at the bottom of the sediment separator 22 is discharged through the sand discharge valve 25. The accumulated water is sucked in by the self-priming pump 23 and sent to the drainage pipeline by the booster pump, and discharged into the main drainage pipe through the one-way valve 44 and the outlet pipe 41 (it can also be discharged to the discharge point through the outlet pipe 41). The one-way valve 44 prevents the water flow in the main drainage pipe from flowing back into the pipeline of the suction volume water removal device.

[0050] When the water accumulation sensor 36 detects that the water level is low, the water inlet valve 24 is closed and the centrifugal fan 33 is started. Under the suction action of the centrifugal fan 33, air together with the accumulated water is sucked in from the air suction head 31, and enters the air-cement separator 32 through the air suction pipeline. The mud sucked in with the air settles to the bottom of the air-cement separator 32 and is discharged from the mud discharge valve. The accumulated water sucked in with the air settles to the middle of the air-cement. The air flow flows into the air intake port of the centrifugal fan 33 from the top of the air-cement separator 32, flows toward the exhaust port after being accelerated by the centrifugal fan 33, and returns to the outer layer of the jacket pipe of the air suction head 31 through the return air pipeline, forming an air flow circulation; the return air pipeline and the outer jacket pipe of the air suction head 31 lead the air flow with a small amount of water mist to the air intake port, forming an air flow circulation without blowing outward.

[0051] The air-cement separator 32 is equipped with a water level sensor 35. When the water level in the air-cement separator 32 is high, the self-priming pump 23 is started, the air-suction outlet valve 34 is opened, and the water in the air-cement separator 32 is pumped to the water outlet pipe 41 by the self-priming pump 23 for discharge. The air-suction moving frame drives the air suction head 31 to move back and forth through the transverse moving member 54, so that the air suction head 31 can absorb water in a larger range. The air-suction moving frame drives the air suction head 31 to move back and forth quickly through the lifting member 53, so that the air suction head 31 repeatedly contacts with the accumulated water and then separates, so that the accumulated water becomes small droplets under the action of the air flow and is sucked into the air-cement separator 32 with the air, so as to prevent the accumulated water from forming a water column in the suction pipeline and blocking the air inlet channel of the fan.

[0052] The above specific implementation methods further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above are only specific implementation methods of the utility model and are not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
