Description

Technical Field

[0001] The invention relates to the technical field of foundation pit drainage, in particular to a fast-moving water pump device and a water pumping method. Background Art

[0002] After rainy weather, especially heavy rain or rainstorms, the water in the foundation pit needs to be drained out in time, otherwise the bearing capacity of the foundation will be reduced, and the foundations of the already constructed building structures and large equipment such as tower cranes in the foundation will produce uneven settlement, which will have an adverse impact on the construction quality and construction safety.

[0003] For the drainage of foundation pits, the most commonly used method is to manually place a water pump for drainage. This method has the problems of high labor intensity, low drainage efficiency, and poor drainage effect. The existing Chinese invention patent with application number CN202011643260.2 discloses an auxiliary device for drainage of foundation pits for water conservancy projects, including a water pumping assembly, a float, a movable control component, a water inlet treatment component, and a floatation component. A water pump is fixed on the top of the float; the movable control component includes two groups of supporting telescopic rods, and the bottoms of the two groups of supporting telescopic rods are respectively fixed to the left and right sides of the top of the mobile base; the water inlet treatment component includes a shell, and the bottom of the protective telescopic rod is fixed to the top of the shell; the floatation component is arranged at the bottom of the float; the above-mentioned auxiliary device for drainage of foundation pits for water conservancy projects is provided with a float and a floating airbag, which does not require manual adjustment at all times, reduces the labor intensity of workers, and improves the drainage effect. In addition, when pumping water, the wireless first controller is controlled by the remote control, which drives the micro servo motor 1, thereby driving the rear wheel to rotate, and the rotating column is driven by the micro servo motor 2 to adjust the moving direction. On the one hand, it increases the pumping range of the device in the foundation pit, and on the other hand, it can avoid clogging of the device due to excessive mud and sand at the pumping position.

[0004] The movement of the above-mentioned device relies on the mobile control parts to move on the ground in the foundation pit. However, the ground of the foundation pit is wet and muddy after being soaked by rainwater, and there may be invisible obstacles such as stones and steel pipes soaked by rainwater at the bottom of the foundation pit. These will hinder the movement of the above-mentioned device in the foundation pit and affect the normal movement and drainage effect of the above-mentioned device. Summary of the Invention

[0043] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0044] Example 1

[0045] like Figure 1 、 Figure 2 As shown, a fast-moving water pump device includes a water pump 1, a mounting frame 4, a float assembly 5, a drive assembly 6, an electrical control box 7, and a battery 8. The mounting frame 4 includes an upper frame and a lower frame connected by a connecting rod. The float assembly 5 includes a protective netting around and at the bottom of the upper and lower frames, and a foam block between the upper and lower frames, which is encased in the protective netting. The float assembly 5 allows the mounting frame 4 to float on the water surface. The water pump 1 is mounted on the mounting frame 4, with the water inlet end connected to the water inlet pipe 2 and the water outlet end connected to the drain hose 3. Two drive assemblies 6 are provided, one on each side of the mounting frame 4. The drive assembly 6 includes a drive motor 601 and a propeller 602. The drive motor 601 is mounted on the mounting frame 4, and the propeller 602 is connected to the output end of the drive motor 601. The drive assembly 6 drives the mounting frame 4 on the water surface and can adjust the direction of movement of the mounting frame 4. An electrical control box 7 is mounted on the mounting frame 4 and contains a first controller and a wireless receiver. The wireless receiver is electrically connected to the input terminal of the first controller, while the drive motor 601 and the water pump 1 are both electrically connected to the output terminal of the first controller. A battery 8 is mounted on the mounting frame 4 and provides power to various electrical devices on the mounting frame 4.

[0046] The operating principle of this embodiment is that a remote controller connected to a wireless receiver in the electrical control box 7 can start and stop the water pump 1 and drive motor 601. By controlling the drive motor 601, the mounting frame 4 and water pump 1 can be moved on the water surface to a suitable position for pumping water. By controlling the water pump 1, the pumping process can be controlled. This device floats on the water surface, similar to the movement of a boat, and is not affected by obstacles such as silt and rocks at the bottom of the foundation pit, making it very convenient to move within the foundation pit.

[0047] Example 2

[0048] like Figure 3 、 Figure 4As shown, a fast-moving water pump device includes a water pump 1, a mounting frame 4, a floating assembly 5, a drive assembly 6, and an electrical control box 7. The mounting frame 4 includes an upper frame and a lower frame, which are connected by a connecting rod. The floating assembly 5 is a plurality of air bags arranged between the upper frame and the lower frame. The floating assembly 5 can make the mounting frame 4 float on the water surface. The water pump 1 is installed on the mounting frame 4. The water inlet end of the water pump 1 is connected to the water inlet pipe 2, and the water outlet end is connected to the drain hose 3. There are two drive assemblies 6, which are respectively arranged on the left and right sides of the mounting frame 4. The drive assembly 6 includes a drive motor 601 and a propeller 602. The drive motor 601 is installed on the mounting frame 4, and the propeller 602 is connected to the output end of the drive motor 601. The drive assembly 6 can drive the mounting frame 4 to move on the water surface and can adjust the movement direction of the mounting frame 4. The electrical control box 7 is mounted on the mounting frame 4. The electrical control box 7 houses a first controller and a wireless receiver. The wireless receiver is electrically connected to the input terminal of the first controller, while the drive motor 601 and the water pump 1 are both electrically connected to the output terminal of the first controller. The electrical control box 7 is connected to a power supply line 10 and an output line 12. The length of the output line 12 is the same as that of the power supply line 10, and the output line 12 is tied together with the power supply line 10. Float blocks 11 are provided at intervals along the length of the power supply line 10 and the output line 12 to keep them afloat.

[0049] like Figure 3 、 Figure 4 As shown, the mounting frame 4 is also provided with a light pole 9, and a night light 14 is provided at the upper end of the light pole 9. The night light 14 is electrically connected to the first controller and can provide lighting for the device when it is used at night. The buoyancy block 11 is provided with a waterproof light 13, which is powered by the output wire 12 and is electrically connected to the first controller. Each waterproof light 13 is used to indicate the position of each buoyancy block 11 at night, and can also indicate the position of the power supply wire 10 and the output wire 12, which helps prevent the power supply wire 10 and the output wire 12 from becoming entangled when the mounting frame 4 is moved.

[0050] Compared with Example 1, this embodiment has the advantages of sustainable power supply, higher pumping efficiency, and is provided with a lighting structure to facilitate nighttime construction.

[0051] Example 3

[0052] like Figure 3 、 Figure 6As shown, a fast-moving water pump device includes a water pump 1, a mounting frame 4, a floating assembly 5, a drive assembly 6, and an electrical control box 7. The mounting frame 4 includes an upper frame and a lower frame, which are connected by a connecting rod. The floating assembly 5 is a plurality of air bags arranged between the upper frame and the lower frame. The floating assembly 5 can make the mounting frame 4 float on the water surface. The water pump 1 is installed on the mounting frame 4. The water inlet end of the water pump 1 is connected to the water inlet pipe 2, and the water outlet end is connected to the drain hose 3. There are two drive assemblies 6, which are respectively arranged on the left and right sides of the mounting frame 4. The drive assembly 6 includes a drive motor 601 and a propeller 602. The drive motor 601 is installed on the mounting frame 4, and the propeller 602 is connected to the output end of the drive motor 601. The drive assembly 6 can drive the mounting frame 4 to move on the water surface and can adjust the movement direction of the mounting frame 4. The electrical control box 7 is mounted on the mounting frame 4. The electrical control box 7 houses a first controller and a wireless receiver. The wireless receiver is electrically connected to the input terminal of the first controller, while the drive motor 601 and the water pump 1 are both electrically connected to the output terminal of the first controller. The electrical control box 7 is connected to a power supply line 10 and an output line 12. The length of the output line 12 is the same as that of the power supply line 10, and the output line 12 is tied together with the power supply line 10. Float blocks 11 are provided at intervals along the length of the power supply line 10 and the output line 12 to keep them afloat.

[0053] like Figure 3 、 Figure 6 As shown, the mounting frame 4 is also provided with a light pole 9, and a night light 14 is provided at the upper end of the light pole 9. The night light 14 is electrically connected to the first controller and can provide lighting for the device when it is used at night. The buoyancy block 11 is provided with a waterproof light 13, which is powered by the output wire 12 and is electrically connected to the first controller. Each waterproof light 13 is used to indicate the position of each buoyancy block 11 at night, and can also indicate the position of the power supply wire 10 and the output wire 12, which helps prevent the power supply wire 10 and the output wire 12 from becoming entangled when the mounting frame 4 is moved.

[0054] like Figure 5 、 Figure 6As shown, a vertical pole 17 is installed in the foundation pit, and a floating block 18 is mounted on the pole 17. The floating block 18 can float freely up and down along the pole 17. A first mounting plate 19 is installed on the pole 17. The first mounting plate 19 is equipped with an ultrasonic ranging sensor 20 and a first control box 21. The ultrasonic ranging sensor 20 is located directly above the floating block 18. The first control box 21 is equipped with a second controller and a wireless transmitter. The ultrasonic ranging sensor 20 is electrically connected to the input terminal of the second controller. The first control box 21 is equipped with a first alarm 22. The first alarm 22 and the wireless transmitter are both electrically connected to the output terminal of the second controller. The wireless transmitter is communicatively connected to the wireless receiver in the electrical control box 7. When the water level in the foundation pit drops due to drainage, the floating block 18 will also drop and will be detected by the ultrasonic ranging sensor 20. The ultrasonic ranging sensor 20 will transmit the detection result to the second controller, and the second controller can calculate the falling height and falling speed of the floating block 18 over a period of time, that is, the falling height and falling speed of the water level in the foundation pit.

[0055] like Figure 5 As shown, the foundation pit is equipped with a large isolation frame 23 and a small isolation frame 24. Both the large isolation frame 23 and the small isolation frame 24 are rectangular frames, each composed of four mesh-covered isolation panels. The small isolation frame 24 is located within the large isolation frame 23, and the two together form a U-shaped frame structure. The vertical pole 17 and the floating block 18 are both located within the small isolation frame 24. The dual-layer filtering and buffering effect of the large isolation frame 23 and the small isolation frame 24 effectively reduces the impact of water surface fluctuations in the foundation pit on the floating block 18, making the detection results of the ultrasonic ranging sensor 20 more accurate, and thus the calculations of the second controller more accurate.

[0056] The method for draining water from a foundation pit according to this embodiment is as follows:

[0057] In the first step, the mounting frame 4 equipped with the water pump 1, the floating assembly 5, the driving assembly 6 and the electric control box 7 is placed in the water in the foundation pit.

[0058] The second step is to vertically set the vertical pole 17 in the foundation pit, put the floating block 18 on the vertical pole 17, install the first mounting plate 19 on the vertical pole 17, and install the ultrasonic ranging sensor 20 and the first control box 21 on the first mounting plate 19.

[0059] The third step is to set the second controller in the first control box 21 so that when the ultrasonic ranging sensor 20 detects that the floating block 18 has dropped more than N meters within M time, the second controller controls the first alarm 22 to sound an alarm. This is to set the speed of water level drop during pumping. The pumping speed cannot be too slow, but it cannot be too fast either. Otherwise, the foundation pit will be soaked in water for a long time or the water level will drop too quickly, which can easily cause the foundation pit slope to collapse and uneven settlement of the building structure and tower crane foundation. Therefore, during the pumping and drainage process, if it is found that the water level drops too quickly, the drainage should be suspended to ensure the safety of the foundation pit slope, building structure and tower crane foundation. When the first alarm 22 sounds, it means that the drainage is too fast. At this time, the second controller controls the wireless transmitter to transmit a signal to the wireless receiver in the electrical control box 7, controlling the water pump 1 to stop pumping. In this way, the water level drop speed in the foundation pit can be automatically detected. When the water level in the foundation pit drops too quickly, the drainage is automatically stopped and an alarm is sounded to remind the staff.

[0060] In the fourth step, the remote control starts the drive motor 601, which drives the propeller 602 to rotate, drives the mounting frame 4 to move on the water surface, and moves the mounting frame 4 and the water pump 1 to a position suitable for pumping water.

[0061] The fifth step is to remotely control the water pump 1 to start the pumping operation.

[0062] When pumping water, the mounting frame 4 and the water pump 1 can be quickly controlled to move to a designated position for pumping and draining water, thereby ensuring the drainage flow and time, and effectively ensuring the precipitation rate of the entire foundation pit.

[0063] Example 4

[0064] like Figure 3 、 Figure 8As shown, a fast-moving water pump device includes a water pump 1, a mounting frame 4, a floating assembly 5, a drive assembly 6, and an electrical control box 7. The mounting frame 4 includes an upper frame and a lower frame, which are connected by a connecting rod. The floating assembly 5 is a plurality of air bags arranged between the upper frame and the lower frame. The floating assembly 5 can make the mounting frame 4 float on the water surface. The water pump 1 is installed on the mounting frame 4. The water inlet end of the water pump 1 is connected to the water inlet pipe 2, and the water outlet end is connected to the drain hose 3. There are two drive assemblies 6, which are respectively arranged on the left and right sides of the mounting frame 4. The drive assembly 6 includes a drive motor 601 and a propeller 602. The drive motor 601 is installed on the mounting frame 4, and the propeller 602 is connected to the output end of the drive motor 601. The drive assembly 6 can drive the mounting frame 4 to move on the water surface and can adjust the movement direction of the mounting frame 4. The electrical control box 7 is mounted on the mounting frame 4. The electrical control box 7 houses a first controller and a wireless receiver. The wireless receiver is electrically connected to the input terminal of the first controller, while the drive motor 601 and the water pump 1 are both electrically connected to the output terminal of the first controller. The electrical control box 7 is connected to a power supply line 10 and an output line 12. The length of the output line 12 is the same as that of the power supply line 10, and the output line 12 is tied together with the power supply line 10. Float blocks 11 are provided at intervals along the length of the power supply line 10 and the output line 12 to keep them afloat.

[0065] like Figure 3 、 Figure 8 As shown, the mounting frame 4 is also provided with a light pole 9, and a night light 14 is provided at the upper end of the light pole 9. The night light 14 is electrically connected to the first controller and can provide lighting for the device when it is used at night. The buoyancy block 11 is provided with a waterproof light 13, which is powered by the output wire 12 and is electrically connected to the first controller. Each waterproof light 13 is used to indicate the position of each buoyancy block 11 at night, and can also indicate the position of the power supply wire 10 and the output wire 12, which helps prevent the power supply wire 10 and the output wire 12 from becoming entangled when the mounting frame 4 is moved.

[0066] like Figure 7 、 Figure 8As shown, a vertical post 17 is installed in the foundation pit. A floating block 18 is mounted on the post 17, allowing it to float freely up and down along the post 17. A second mounting plate 25 is installed at the upper end of the post 17. A guide tube 26 is mounted on the second mounting plate 25. A guide rod 27 is vertically mounted in the guide tube 26. The second mounting plate 25 has a through hole for the guide rod 27 to pass through. The guide rod 27 passes through the through hole provided in the guide tube 26 and the second mounting plate 25. A length scale 32 is provided along the length of the guide rod 27. When adjusting the height of the guide rod 27, the length scale 32 can be used to precisely control the vertical adjustment distance of the guide rod 27. The guide tube 26 has a threaded through hole leading into the tube, and a fixing bolt 28 is installed in this threaded through hole to secure the guide rod 27. An L-shaped frame 15 is mounted on the floating block 18. A proximity switch 16 is mounted on the L-shaped frame 15. The proximity switch 16 is located directly below a guide rod 27, the lower end of which is provided with a sensor plate. A second control box 29 is mounted on the second mounting plate 25. This second control box 29 houses a time relay, a first contactor, and a second contactor. A second alarm 30 and a third alarm 31 are also mounted on the second control box 29. The proximity switch 16 is electrically connected to the second alarm 30 via the first contactor. When the proximity switch 16 loses the sensor plate at the lower end of the guide rod 27, the second alarm 30 activates. The time relay is electrically connected to the third alarm 31 via the second contactor. When the timer set on the time relay reaches zero, the third alarm 31 activates. The second and third alarms 30 and 31 use different alarms and emit different alarm signals, such as different alarm sounds. This facilitates distinguishing between the second and third alarms 30 and 31.

[0067] like Figure 7 As shown, the foundation pit is equipped with a large isolation frame 23 and a small isolation frame 24. Both the large isolation frame 23 and the small isolation frame 24 are rectangular frames composed of four mesh-covered isolation panels. The small isolation frame 24 is located within the large isolation frame 23, forming a U-shaped frame structure. The vertical pole 17 and the floating block 18 are both located within the small isolation frame 24. The dual-layer filtering and buffering effect of the large isolation frame 23 and the small isolation frame 24 effectively reduces the impact of water surface fluctuations in the foundation pit on the floating block 18, making the detection of the proximity switch 16 more accurate.

[0068] The method for draining water from a foundation pit according to this embodiment is as follows:

[0069] In the first step, the mounting frame 4 equipped with the water pump 1, the floating assembly 5, the driving assembly 6 and the electric control box 7 is placed in the water in the foundation pit.

[0070] In the second step, the vertical pole 17 is set in the foundation pit, the floating block 18 equipped with the proximity switch 16 is put on the vertical pole 17, the second mounting plate 25 is installed on the vertical pole 17, and the guide rod 27 and the second control box 29 are installed on the second mounting plate 25.

[0071] In the third step, the maximum detection distance of the proximity switch 16 is measured as L, and the time relay in the second control box 29 is set to P. The P value should satisfy that the maximum height of the water level in the foundation pit allowed to drop within the P time is the same as L.

[0072] The fourth step is to adjust the height of the guide rod 27 so that the lower end of the guide rod 27 contacts the detection end of the proximity switch 16 , that is, the sensing piece of the guide rod 27 contacts the detection end of the proximity switch 16 .

[0073] In the fifth step, the remote control starts the driving motor 601, which drives the propeller 602 to rotate, and drives the mounting frame 4 to move on the water surface, and moves the mounting frame 4 to a position suitable for pumping water.

[0074] Step 6: Remotely control the water pump 1 to start pumping water.

[0075] Step 7: If the second alarm 30 sounds but the third alarm 31 does not, it means that the water level in the foundation pit is dropping too fast and the water is being pumped too fast, and the water pump 1 needs to be controlled to stop pumping. If the third alarm 31 sounds but the second alarm 30 does not, it means that the water level in the foundation pit is dropping within a reasonable range and the pumping speed is within a reasonable range. Pumping can continue, but the timing of the time relay and the height position of the guide rod 27 need to be reset.

[0076] Compared with Example 3, this embodiment also has the function of monitoring the rate of water level drop in the foundation pit. The monitoring mechanism of this embodiment does not have the function of automatically stopping drainage when it detects that the water level in the foundation pit is dropping too quickly. In addition, this embodiment requires multiple settings during use. However, compared with the monitoring mechanism of Example 3, the monitoring mechanism of this embodiment has the advantage of lower electrical component configuration costs.

[0077] The above is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
