Abstract
Description
Technical Field
[0001] The present application relates to the technical field of foundation pit drainage, and in particular to an automatic sensing foundation pit drainage device and a method of using the same. Background Art
[0002] A foundation pit drainage system is a device specifically designed to remove water from a foundation pit. Its primary function is to collect water within the pit, pump it out through a pump mechanism, and discharge it to the outside. Its main structure consists of a drainage channel within the pit, a collection well within the channel, a drainage well outside the pit, and a pump located on one side of the drainage well, with the pumping end extending into the collection well. The system primarily removes water from the pit by activating the pump.
[0003] However, the water pump needs to be manually controlled to start. Therefore, when it rains at night on the construction site, the drainage device in the prior art cannot drain the accumulated water in time, causing the accumulated water to overflow from the water collection well, softening the foundation pit soil, and thus reducing the bearing capacity of the soil. In order to solve this technical problem in the prior art, a liquid level sensor is usually set at the bottom of the water collection well, and the liquid level sensor signal is connected to the water pump. When there is water in the water collection well, the liquid level sensor detects the liquid level signal and starts the water pump to pump water, solving the problem of not being able to drain the accumulated water in time at night. However, if the rain is light, this situation will occur: the liquid level sensor detects the liquid level signal and starts the water pump to pump water. Since the rain is light, the water pump can quickly pump out the accumulated water, but the rain is still light, which will cause the water pump to frequently switch on and off, reducing the service life of the water pump and consuming a lot of energy. For this reason, the present application proposes an automatic sensing foundation pit drainage device and its use method, which is used to save energy consumption during the drainage process. Summary of the Invention
[0004] In view of the shortcomings of the existing technology, the purpose of this application is to provide an automatic sensing foundation pit drainage device and a method of use thereof, which are used to save energy consumption during the drainage process.
[0005] The above-mentioned purpose of the present application is achieved through the following technical solutions: an automatic sensing foundation pit drainage device, including a drainage channel opened in the foundation pit, a water collection well opened in the drainage channel, a drainage well opened outside the foundation pit, a drainage channel opened on one side of the bottom end of the drainage well and connected to the water collection well, a liquid level sensor arranged at the bottom end of the water collection well, and a closing device arranged in the drainage channel near one end of the drainage well and connected to the liquid level sensor by signal, wherein the closing device is used to close the drainage channel.
[0006] Furthermore, the closing device includes a mounting frame, a mounting groove provided on the inner bottom surface of the mounting frame, a servo motor installed in the mounting groove, and a sealing plate installed on the output end of the servo motor for sealing the inner space of the mounting frame. The output end of the servo motor faces upward and extends to the top of the inner part of the mounting frame and is rotatably connected to the mounting frame. The servo motor signal is connected to the liquid level sensor.
[0007] By adopting the above technical solution, after the construction of the day is completed, the staff will install the liquid level sensor at the bottom of the water collection well. When it rains at night and rainwater enters the water collection well through the drainage channel, the liquid level sensor detects the liquid level signal and starts the servo motor. The output end of the servo motor rotates so that the sealing plate no longer blocks the internal space of the installation frame, making the water collection well and the drainage well interconnected (the accumulated water in the drainage well is discharged into the nearby natural waters after the construction of the day is completed). At this time, the accumulated water in the water collection well enters the drainage well through the drainage channel, and because the water collection well and the drainage well are interconnected, the liquid level sensor always detects the liquid level signal, so that the closing device remains in an open state, and there will be no frequent opening and closing of the closing device, saving energy consumption. When the staff needs to work during the day, the liquid level sensor is taken out, so that the output end of the servo motor drives the sealing plate to block the internal space of the installation frame, so that the drainage channel is closed, and then the staff can take out the water pump to carry out construction work (if the drainage channel is not closed, the water in the water collection well will not be able to be discharged when the staff is working, resulting in subsequent construction difficulties).
[0008] Furthermore, a control platform located near the drainage well is provided on one side of the foundation pit, and the liquid level sensor is connected to the control platform by wires.
[0009] By adopting the above technical solution, it is more convenient for workers to install the liquid level sensor at the bottom of the water collection well. They only need to use the wire to slowly place the liquid level sensor to the bottom of the water collection well, and they can also use the wire to recover the liquid level sensor.
[0010] Furthermore, a rainproof structure is provided around the drainage well to prevent rainwater from entering the drainage well.
[0011] Furthermore, the rain shield structure includes two fixed plates and a mounting plate respectively arranged on both sides of the drainage well and opposite to each other. The upper end of the fixed plate is provided with a plug interface, and the upper end of the mounting plate is connected to a rain shield that passes through the mounting plate.
[0012] By adopting the above technical solution, although the setting of the drainage channel and the closing device saves energy consumption, when it rains, rainwater will also enter the drainage well. Under normal circumstances, there will be no impact, but when the rain is particularly heavy, the drainage well receives rainwater, which will cause the rainwater in the drainage well to rise too quickly, which may cause the rainwater in the collection well to overflow. The setting of the rainproof structure solves this technical problem. Through the setting of the rainproof structure, after the construction is completed, the staff pushes the rain shield into the socket slot so that the rain shield blocks the space above the drainage well to prevent rainwater from entering the drainage well. This can effectively slow down the speed at which the rainwater in the drainage well rises and prevent the rainwater in the collection well from overflowing. The rainproof structure does not affect the normal use of the sump pump. When the staff needs to use the sump pump, they only need to pull the rain shield out of the socket slot.
[0013] Furthermore, a limiting groove is provided on the upper surface of one end of the rain shield close to the fixed plate along the width direction of the rain shield, and a limiting structure is provided on the upper end of the fixed plate for limiting the rain shield from detaching from the plug-in slot through the limiting groove.
[0014] Furthermore, the limiting structure includes a portal frame arranged at the top of the fixed plate, a limiting plate arranged between the portal frame and the fixed plate and plugged into the fixed plate, and a supporting spring arranged between the portal frame and the limiting plate for pushing the limiting plate into the plug-in slot.
[0015] By adopting the above technical solution, although the setting of the rain shield structure can effectively slow down the speed of the rising of rainwater in the drainage well, due to certain special circumstances, the rain shield cannot completely block the space above the drainage well. For example, when the rain shield is subjected to large vibration or wind, it is easy to fall out of the plug-in slot, resulting in the rain shield being unable to block the rain; the setting of the limiting structure solves this technical problem. Through the setting of the limiting structure, when the staff pushes the rain shield to insert it into the plug-in slot, the end of the rain shield will move upward against the limiting plate to compress the support spring. At this time, the rain shield continues to be pushed so that the limiting slot is aligned with the limiting plate, so that the support spring pushes the limiting plate into the limiting slot to fix the rain shield. In this way, when the rain shield is subjected to large vibration or wind, it will not fall off the plug-in slot, which improves the stability of the rain shield. Moreover, the setting of the limiting structure can restrict the fixing plate and the installation plate together, making it more convenient for the staff to carry the rain shield structure.
[0016] Furthermore, fixing rings are provided on both sides of the installation frame, and a recovery device for recovering the closing device through the fixing rings is provided around the drainage well.
[0017] Furthermore, the recovery device includes a base plate, two recovery plates arranged on the base plate and opposite to each other, a winding drum arranged between the two recovery plates and rotatably connected to the recovery plates, a recovery rope wound on the winding drum, and a recovery motor arranged on one side of the recovery plate and with the output end fixedly connected to the winding drum. Two fixing ropes for connecting to a fixing ring are provided at one end of the recovery rope away from the winding drum.
[0018] By adopting the above technical solution, after the workers install the closing device in the drainage channel, they will tie the two fixed ropes to the two fixed rings respectively. When the construction on the construction site is completed, they only need to start the recovery motor to rotate the reel to reel in the recovery rope. The recovery rope drives the fixed rope to pull the installation frame, so that the entire closing device is recovered, making it more convenient for the workers to recover the closing device.
[0019] A method for using an automatic sensing foundation pit drainage device applied to the above technical solution includes the following steps:
[0020] S1. Open a drainage channel in the foundation pit, then open a water collection well in the drainage channel, and then open a drainage well outside the foundation pit with the bottom flush with the water collection well;
[0021] S2. Open a drainage channel connected to the water collection well at the bottom of the drainage well near the water collection well;
[0022] S3. Installing a closing device in the drainage channel and making the periphery of the installation frame fit the inner wall of the drainage channel;
[0023] S4. Tie the fixed rope to the fixed ring;
[0024] S5. Place the liquid level sensor at the bottom of the water collection well;
[0025] S6. Push the rain shield into the insertion slot so that the end of the rain shield moves upward against the limit plate to compress the support spring. Then continue to push the rain shield so that the limit slot is aligned with the limit plate, so that the support spring pushes the limit plate into the limit slot to fix the rain shield.
[0026] In summary, this application includes at least one of the following beneficial technical effects:
[0027] 1. Through the setting of drainage channels and closing devices, after the construction of the day is completed, the staff will install the liquid level sensor at the bottom of the water collection well. When it rains at night and rainwater enters the water collection well through the drainage channel, the liquid level sensor detects the liquid level signal and starts the servo motor. The output end of the servo motor rotates so that the sealing plate no longer blocks the internal space of the installation frame, so that the water collection well and the drainage well are connected to each other (the accumulated water in the drainage well is discharged into the nearby natural waters after the construction of the day is completed). At this time, the accumulated water in the water collection well enters the drainage well through the drainage channel, and because the water collection well and the drainage well are connected to each other, the liquid level sensor always detects the liquid level signal, so that the closing device remains in an open state, and the closing device will not be frequently opened and closed, thereby achieving the purpose of saving energy consumption.

DETAILED DESCRIPTION
[0034] The present application is further described in detail below with reference to the accompanying drawings.
[0035] Example, see Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4, an automatic sensing foundation pit drainage device, including a drainage channel 10 opened in the foundation pit 1, a water collection well 11 opened in the drainage channel 10, a drainage well 12 opened outside the foundation pit 1, a drainage channel 13 opened on one side of the bottom end of the drainage well 12 and connected to the water collection well 11, a liquid level sensor 2 arranged at the bottom end of the water collection well 11 and a closing device 3 arranged in the drainage channel 13 near one end of the drainage well 12 and connected to the liquid level sensor 2 by signal. The closing device 3 is used to close the drainage channel 13, the closing device 3 includes a mounting frame 30, a mounting groove opened on the bottom surface of the mounting frame 30, a servo motor 31 installed in the mounting groove and a sealing plate 32 installed on the output end of the servo motor 31 for blocking the internal space of the mounting frame 30, the output end of the servo motor 31 faces upward and extends to the top of the mounting frame 30 and is rotatably connected to the mounting frame 30, the signal of the servo motor 31 is connected to the liquid level sensor 2, after the construction is completed on the day, the staff will install the liquid level sensor 2 at the bottom of the water collection well 11, when it rains at night, rainwater enters the collection well through the drainage channel 10 When in the water well 11, the liquid level sensor 2 detects the liquid level signal and starts the servo motor 31. The output end of the servo motor 31 rotates, so that the sealing plate 32 no longer blocks the internal space of the installation frame 30, so that the water collection well 11 and the drainage well 12 are connected to each other (the accumulated water in the drainage well 12 is discharged into the nearby natural waters after the construction of the day is completed). At this time, the accumulated water in the water collection well 11 enters the drainage well 12 through the drainage channel 13, and because the water collection well 11 and the drainage well 12 are connected to each other, the liquid level sensor 2 always detects the liquid level signal, so that the closing device 3 remains in an open state, and the closing device 3 does not frequently open and close, saving energy consumption. When the staff needs to work during the day, the liquid level sensor 2 is taken out, so that the output end of the servo motor 31 drives the sealing plate 32 to block the internal space of the installation frame 30, so that the drainage channel 13 is closed, and then the staff can take out the water pump to carry out construction work (if the drainage channel 13 is not closed, the water in the water collection well 11 will not be able to be discharged when the staff is working, resulting in subsequent construction difficulties).
[0036] Reference Figure 5 In this embodiment, a control platform 20 is provided on one side of the foundation pit 1 near the drainage well 12, and the liquid level sensor 2 is connected to the control platform 20 by wires, making it more convenient for the staff to install the liquid level sensor 2 at the bottom of the water collection well 11. The liquid level sensor 2 only needs to be slowly placed to the bottom of the water collection well 11 using the wires, and the liquid level sensor 2 can also be recovered using the wires.
[0037] Although the arrangement of the drainage channel 13 and the closing device 3 saves energy consumption, rainwater will also enter the drainage well 12 when it rains. Under normal circumstances, there will be no impact. However, when it rains heavily, the drainage well 12 receives rainwater, which will cause the rainwater in the drainage well 12 to rise too quickly, which may cause the rainwater in the water collection well 11 to overflow. In order to solve this technical problem, this embodiment is provided with a rainproof structure 4 around the drainage well 12 to prevent rainwater from entering the drainage well 12. The rainproof structure 4 includes two fixed plates 40 respectively arranged on both sides of the drainage well 12 and opposite to each other, and an installation Plate 41, the upper end of the fixing plate 40 is provided with an insertion port 42, and the upper end of the mounting plate 41 is connected with a rain shield 43 passing through the mounting plate 41. After the construction is completed, the staff pushes the rain shield 43 into the insertion slot, so that the rain shield 43 blocks the space above the drainage well 12 to prevent rainwater from entering the drainage well 12. In this way, the speed of the increase of rainwater in the drainage well 12 can be effectively slowed down, and the overflow of rainwater in the water collection well 11 can be prevented. The rain shield structure 4 does not affect the normal use of the water pump. When the staff needs to use the water pump, they only need to pull the rain shield 43 out of the insertion slot.
[0038] Although the setting of the rain shield structure 4 can effectively slow down the speed of the rainwater rising in the drainage well 12, due to certain special circumstances, the rain shield 43 cannot completely block the space above the drainage well 12. For example, when the rain shield 43 is subjected to large vibration or wind, it is easy to disengage from the plug-in slot, resulting in the rain shield 43 being unable to block the rain. In order to solve this technical problem, this embodiment provides a limiting groove 44 along the width direction of the rain shield 43 on the upper surface of the end of the rain shield 43 close to the fixed plate 40, and the upper end of the fixed plate 40 is provided with a limiting structure 5 for limiting the rain shield 43 from disengaging from the plug-in slot through the limiting groove 44. The limiting structure 5 includes a door frame 50 arranged at the top of the fixed plate 40, and a limiting plate 51 arranged between the door frame 50 and the fixed plate 40 and plugged into the fixed plate 40. And the support spring 52 arranged between the door frame 50 and the limit plate 51 is used to push the limit plate 51 into the plug-in slot. Through the setting of the limit structure 5, when the staff pushes the rain shield 43 to insert it into the plug-in slot, the end of the rain shield 43 will move upward against the limit plate 51 to compress the support spring 52. At this time, the rain shield 43 is continued to be pushed so that the limit slot 44 is aligned with the limit plate 51, so that the support spring 52 pushes the limit plate 51 into the limit slot 44 to fix the rain shield 43. In this way, when the rain shield 43 is subjected to large vibration or wind, it will not fall off the plug-in slot, thereby improving the stability of the rain shield 43. Moreover, through the setting of the limit structure 5, the fixing plate 40 and the mounting plate 41 can be restricted together, making it more convenient for the staff to carry the rain shield structure 4.
[0039] The closure device 3 is retracted by the reel 62 and the reel 63 is retracted by the reel 62.
[0040] Specific implementation process: first, open a drainage channel 10 in the foundation pit 1, then open a water collection well 11 in the drainage channel 10, and then open a drainage well 12 with the bottom flush with the water collection well 11 outside the foundation pit 1, and then open a drainage channel 13 connected to the water collection well 11 on the side of the bottom of the drainage well 12 close to the water collection well 11, and then install the closing device 3 in the drainage channel 13 and make the periphery of the mounting frame 30 fit the inner wall of the drainage channel 13, and then tie the fixing rope 65 to the fixing ring 33, and then put the liquid level sensor 2 into the bottom of the water collection well 11, and then push the rain shield 43 into the plug-in slot, so that the end of the rain shield 43 moves upward against the limit plate 51 to compress the support spring 52, and then continue to push the rain shield 43 so that the limit slot 44 is aligned The limiting plate 51 allows the supporting spring 52 to push the limiting plate 51 into the limiting groove 44 to fix the rain shield 43. When it rains at night and rainwater enters the water collection well 11 through the drainage channel 10, the liquid level sensor 2 detects the liquid level signal and starts the servo motor 31. The output end of the servo motor 31 rotates so that the blocking plate 32 no longer blocks the internal space of the mounting frame 30, so that the water collection well 11 and the drainage well 12 are connected to each other. At this time, the accumulated water in the water collection well 11 enters the drainage well 12 through the drainage channel 13, and because the water collection well 11 and the drainage well 12 are connected to each other, the liquid level sensor 2 always detects the liquid level signal, so that the closing device 3 remains in an open state, and the closing device 3 will not be frequently opened and closed, saving energy consumption.
[0041] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
