Description

Technical Field

[0001] This invention relates to the field of foundation pit drainage engineering technology, and in particular to an intelligent foundation pit dewatering device based on a BIM three-dimensional model. Background Technology

[0002] BIM (Building Information Modeling) is a complete information model that integrates engineering information, processes, and resources at different stages throughout the entire lifecycle of a project. It uses various relevant data of the building project as the foundation for building model creation, simulating the real information of the building through digital information. Intelligent drainage engineering for foundation pits is a part of BIM 3D models. Intelligent drainage mainly addresses water accumulation at the bottom of the foundation pit caused by surface precipitation or surface drainage subsidence, as well as atmospheric precipitation outside the surface. After the foundation pit is formed, a concrete foundation is poured on its foundation to build a footing. To ensure the foundation pit can be constructed under dry conditions and to prevent slope instability, quicksand, pit bottom heave, and piping, appropriate drainage devices are needed to drain and dewater the foundation pit.

[0003] During the construction of the foundation pit, it is necessary to do a good job of drainage. Since the foundation pit contains a lot of soil, the drainage process will carry a lot of soil, which can easily cause blockage during the drainage process, affecting the drainage effect and prolonging the drainage cycle. At the same time, the water carrying soil needs to be discharged into the ditch, which can easily cause silt to accumulate in the ditch and cause environmental pollution. Summary of the Invention

[0004] This invention discloses an intelligent dewatering device for foundation pits based on BIM three-dimensional models, which aims to solve the technical problem of difficult mud-water separation in foundation pit drainage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A BIM-based intelligent dewatering device for foundation pits includes an outer shell assembly. A first drive mechanism for separating mud and water is installed in the upper middle part of the outer shell assembly. A mud-water separation mechanism is located inside the upper part of the outer shell assembly. A filter mechanism for preventing mud blockage is located to the right of the mud-water separation mechanism. A second drive mechanism for discharging mud is installed on the upper right side of the outer shell assembly. An alarm mechanism for monitoring the amount of mud accumulation is located inside the lower part of the outer shell assembly. A transmission mechanism for cleaning the filter cloth and discharging mud is located to the right of the alarm mechanism. A water pump is installed on the right side of the outer shell assembly.

[0007] By setting up a first drive mechanism and a filter mechanism to assist the mud-water separation mechanism, the cement separation effect is achieved. An alarm mechanism reminds the second drive mechanism to discharge mud in a quantitative manner.

[0008] In a preferred embodiment, the housing assembly includes a device body, the lower left side of which has a movable groove, and the front and rear ends of the movable groove have first sliding grooves.

[0009] By setting up a moving groove and a first sliding groove, the door frame assembly can be opened to facilitate the discharge of soil.

[0010] In a preferred embodiment, the first drive mechanism includes a dual-head motor mounted on the upper middle part of the device body, with gears connected to the left and right output ends of the dual-head motor, and baffle plates meshing between the front and rear ends of the gears.

[0011] By setting up two sets of baffles driven by a dual-head motor and gear transmission, the mud-water separation mechanism is blocked by alternating baffles, thereby achieving the function of mud-water separation.

[0012] In a preferred embodiment, the mud-water separation mechanism includes a pipe installed at the upper end of the device body. The pipe has channel grooves at both the front and rear ends, second sliding grooves at the left and right ends, and a discharge port at the lower end of the channel groove. Telescopic cylinders are provided at both the front and rear ends of the discharge port, and a discharge baffle is connected to the output end of the telescopic cylinder.

[0013] By setting two sets of channel grooves inside the pipeline, one channel groove is closed and the other is open, ensuring that the mud and water are discharged without interruption and the mud is discharged into the channel groove automatically by setting a telescopic cylinder and a discharge baffle.

[0014] In a preferred embodiment, the filtration mechanism includes a mounting frame installed on the right side of the pipe, a filter bag installed in the middle of the left side of the mounting frame, and sliding columns provided at the front and rear ends of the left side of the mounting frame.

[0015] By setting up filter bags to filter and block the mud in the muddy water, blockage caused by mud in subsequent drainage can be prevented.

[0016] In a preferred embodiment, the second drive mechanism includes a first motor mounted on the upper right side of the device body, the output end of the first motor being connected to a rotating shaft, and a pull rope being wound around the outer surface of the rotating shaft.

[0017] By setting a rotating shaft to drive the winding and unwinding of the rope, the transmission function of the internal structure of the equipment is achieved.

[0018] In a preferred embodiment, the alarm mechanism includes a base fixedly installed inside the lower end of the device body, with first springs connected to the four sides of the base, a sensor plate disposed in the middle of the base, a supporting inclined platform slidably connected to the upper end of the base, a sensor installed in the middle of the lower end of the supporting inclined platform, and an alarm installed at the upper end of the device body.

[0019] By supporting the inclined platform to slide on the base, the alarm will sound when the sensor comes into contact with the sensing plate, thus achieving the effect of automatic soil discharge.

[0020] In a preferred embodiment, the transmission mechanism includes a sliding frame slidably connected to the outer surface of the sliding column, a connecting rod connected to the lower end of the sliding frame, a second arc-shaped clamping plate connected to the lower end of the connecting rod, and a scraper provided on the right side of the sliding frame.

[0021] By setting up a connecting rod and a sliding frame, the connecting rod is linked with the supporting inclined platform, thereby enabling the scraper to scrape and clean the surface of the filter cloth, reducing clogging.

[0022] In a preferred embodiment, the transmission mechanism further includes a door frame assembly installed at the lower end of the moving groove. The door frame assembly includes a moving door slidably connected inside the moving groove. A second spring is connected to the front and rear ends of the upper part of the moving door. A slider is slidably connected to the front and rear ends of the left side of the moving door. A third spring is connected to the right side of the slider. A first arc-shaped plate is connected to the left side of the slider. A wedge-shaped groove is opened at the upper end of the slider. A wedge-shaped block is provided at the upper end of the first groove. The wedge-shaped groove and the wedge-shaped block are fitted together.

[0023] By setting a second spring and a slider, the first arc-shaped plate and the second arc-shaped plate can be easily engaged, thereby enabling the first arc-shaped plate to drive the moving door to move. At the same time, wedge-shaped blocks and wedge-shaped grooves are set to cause the first arc-shaped plate and the second arc-shaped plate to be misaligned and separated. The moving door is automatically reset by the second spring, thereby realizing the automatic opening and closing of the moving door to facilitate the discharge of soil.

[0024] In a preferred embodiment, a partition plate is provided in the middle of the device body, a second motor is installed at the lower rear end of the device body, the output end of the second motor is connected to a mud-removing plate, and brushes are provided at both ends of the upper end of the mud-removing plate.

[0025] By setting up baffles and mud-removing plates, the soil discharge rate is increased, and the mud-removing plates and brushes reduce the phenomenon of soil accumulation in dead corners.

[0026] The present invention provides an intelligent dewatering device for foundation pits based on BIM three-dimensional models, which has the following improvements and advantages:

[0027] Firstly, a BIM-based intelligent drainage device for foundation pits uses filter bags to filter and block the mud in the muddy water, causing the mud to accumulate inside the channel trough. This prevents blockages caused by mud during subsequent drainage or environmental pollution caused by the discharge ditch. Furthermore, a telescopic cylinder drives a discharge baffle to remove the mud, ensuring the normal operation of the channel trough. At the same time, by setting baffles to regularly close and open the channel trough, mud-water separation is achieved even with continuous mud-water discharge.

[0028] Secondly, a BIM-based intelligent drainage device for foundation pits applies pressure to the supporting inclined platform using the weight of the soil, causing the sensor to contact the sensing plate. This triggers an alarm and automatically drives the device to quantitatively discharge soil, achieving intelligent operation. Each alarm corresponds to one soil discharge. The BIM 3D model monitors and records the number of soil discharges and roughly calculates the amount of soil discharged, facilitating soil metering and collection for foundation pit support or other convenient uses, thus reducing environmental pollution caused by soil drainage ditches.

[0029] Thirdly: A smart drainage device for foundation pits based on BIM 3D models, which uses a transmission link to drive a sliding frame during the displacement of the inclined platform, causing the scraper to scrape and clean the surface of the filter bag, thereby reducing the clogging of the filter bag and preventing excessive drainage resistance.

[0030] Fourthly: A smart drainage device for foundation pits based on BIM three-dimensional models, which uses a second arc-shaped card plate to be misaligned and engaged with the first arc-shaped card plate, and a rope-driven sliding frame to cause the second arc-shaped card plate to drive the sliding door to open, thereby realizing the discharge of soil. At the same time, the rope-driven sliding frame resets to achieve secondary scraping of the filter bag surface, improving the filter bag's anti-clogging effect.

[0031] Fifthly: A smart drainage device for foundation pits based on BIM three-dimensional models, which, by setting wedge-shaped blocks and wedge-shaped grooves, causes the first arc-shaped card plate and the second arc-shaped card plate to be misaligned and separated, and the sliding door is automatically reset by the second spring, thereby realizing the automatic closing of the sliding door so that the soil inside the device can be discharged in a quantitative manner after accumulation.

Detailed Implementation

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0042] The intelligent dewatering device for foundation pits based on BIM three-dimensional models disclosed in this invention is mainly used in foundation pit drainage and mud-water separation scenarios.

[0043] Reference Figure 1 , Figure 2 and Figure 3 A smart dewatering device for foundation pits based on a BIM 3D model includes an outer shell assembly 1. A first drive mechanism 2 for separating mud and water is installed in the middle of the upper part of the outer shell assembly 1. A mud-water separation mechanism 3 for separating mud and water is provided in the upper part of the inner shell assembly 1. A filter mechanism 4 for blocking mud is provided on the right side of the mud-water separation mechanism 3. A second drive mechanism 5 for discharging mud is installed in the right side of the upper part of the outer shell assembly 1. An alarm mechanism 6 for the amount of mud accumulation is provided in the lower part of the inner shell assembly 1. A transmission mechanism 7 for cleaning the filter cloth and discharging mud is provided on the right side of the alarm mechanism 6. A water pump 8 is installed in the right side of the outer shell assembly 1.

[0044] In this embodiment: During the foundation pit drainage process, water is first pumped from the foundation pit by driving water pump 8. The muddy water in the foundation pit enters from the left side of the outer shell assembly 1. At that time, the first drive mechanism 2 is activated, causing one side of the two sets of channels inside the mud-water separation mechanism 3 to be closed and the other side to be unobstructed. At the same time, the filter mechanism 4 blocks the mud in the muddy water. The filtered water is discharged from the right side of the outer shell assembly 1, thereby ensuring that the mud accumulates in the channel. Thus, mud discharge is carried out during the channel closure process, thereby reducing the blockage phenomenon that may occur in the subsequent discharge process. The discharged mud enters the lower end of the inner shell assembly 1 and falls on the alarm mechanism 6. The mud gradually accumulates, and the weight of the mud acts on the alarm mechanism 6, thereby triggering an alarm. The second drive mechanism 5 is automatically driven to drive the transmission mechanism 7 to carry out mud discharge. The automatic drive method with alarm prompts realizes the intelligent effect of the equipment. At the same time, each alarm issued by the alarm mechanism 6 is a mud discharge. The number of mud discharges is monitored and recorded by the BIM three-dimensional model, thereby realizing the approximate calculation of the mud discharge volume, which facilitates the metering and collection of mud for subsequent use in supporting the foundation pit or other aspects.

[0045] In the previous embodiment, the foundation pit was drained. Considering the potential for blockage caused by excessive soil in the foundation pit, the specific operation was as follows:

[0046] Reference Figure 1 , Figure 3 and Figure 4In a preferred embodiment, the first drive mechanism 2 includes a double-headed motor 201 installed in the middle of the upper part of the device body 101. The output ends of the double-headed motor 201 are connected to gears 202. The front and rear ends of the gears 202 are meshed with baffles 203. The mud-water separation mechanism 3 includes a pipe 301 installed in the upper part of the device body 101. The pipe 301 has channel grooves 302 at the front and rear ends. The channel grooves 302 have second sliding grooves 303 at the left and right ends. The channel grooves 302 have a discharge port 304 at the lower end. The discharge port 304 has telescopic cylinders 305 at the front and rear ends. The output end of the telescopic cylinders 305 is connected to a discharge baffle 306.

[0047] In this embodiment: muddy water enters from the left side of the outer casing assembly 1 and is then introduced into the pipe 301. Two sets of channel grooves 302 are formed inside the pipe 301. One set of channel grooves 302 is closed by the baffle plate 203 engaging with the second slide groove 303. Therefore, the muddy water passes through the other set of channel grooves 302. During the passage of muddy water, the mud and soil in the muddy water are blocked and accumulate inside the channel groove 302. After a certain period of time, the dual-head motor 201 automatically starts, driving the gear 202 to move the two sets of baffle plates 203. The baffle plate 203 that closes the channel moves upward along the second slide groove 303, while the baffle plate 203 that opens the channel... 03. The material moves downward along the second chute 303, thereby opening the closed channel and closing the open channel. As a result, the mud and water can pass through the new channel, thus ensuring uninterrupted mud and water discharge. At this time, the mud that was previously blocked and accumulated in the open and closed channel remains. Then, the telescopic cylinder 305 is driven to open the lower end of the closed discharge baffle 306, thus achieving the effect of mud discharge. After the mud is discharged, it resets. Therefore, the timed dual-head motor 201 automatically drives the baffle 203 to alternately close and open the two sets of channel grooves 302 at regular intervals, thereby ensuring the mud discharge channel is maintained while the mud and water discharge is uninterrupted.

[0048] In the previous embodiment, the soil needs to be piled up in the channel trough 302. Considering that the soil cannot be separated from the muddy water, the specific operation is as follows:

[0049] Reference Figure 3 and Figure 5 In a preferred embodiment, the filtration mechanism 4 includes an installation frame 401 installed on the right side of the pipe 301, a filter bag 402 installed in the middle of the left side of the installation frame 401, and sliding columns 403 provided at the front and rear ends of the left side of the installation frame 401.

[0050] In this embodiment: after the muddy water enters the channel trough 302, the filter bag 402 on the mounting frame 401 installed on the right side of the pipe 301 blocks the mud in the muddy water, thereby ensuring that the mud accumulates inside the channel trough 302 and facilitates the mud discharge.

[0051] In the first embodiment, the soil is separated and discharged from the mud-water separation mechanism 3 and falls into the lower part of the inner shell assembly 1. Considering that the soil needs to be treated inside the device, the specific operation is as follows:

[0052] Reference Figure 2 and Figure 3 In a preferred embodiment, the alarm mechanism 6 includes a base 601 fixedly installed inside the lower end of the device body 101. The four sides of the base 601 are connected with first springs 602. A sensor 603 is disposed in the middle of the base 601. A support inclined platform 604 is slidably connected to the upper end of the base 601. A sensor 605 of model RE13-SA05 is installed in the middle of the lower end of the support inclined platform 604. An alarm 606 of model ZYJDS is installed on the upper end of the device body 101.

[0053] In this embodiment: after the soil is discharged from the mud-water separation mechanism 3, it falls onto the upper surface of the support inclined platform 604. With repeated soil introduction, more and more soil accumulates on the upper surface of the support inclined platform 604, and the weight of the soil becomes heavier and heavier, causing the support inclined platform 604 to slowly slide down on the base 601. As a result, the first spring 602 contracts. When a certain amount of soil accumulates at the lower end of the device body 101, the sensor 605 at the lower end of the support inclined platform 604 contacts the sensing plate 603, thereby triggering the alarm 606 to issue an alarm warning and automatically driving the corresponding device to implement quantitative soil discharge. Through each alarm warning, the BIM three-dimensional model monitors and records the number of soil discharges, thereby realizing the approximate calculation of the soil discharge amount.

[0054] In the previous embodiment, the inclined platform 604 is supported by the displacement of soil by weight. Considering the linkage effect between the cleaning of the filter bag 402 surface and the discharge of soil from the device body 101, the specific operation is as follows:

[0055] Reference Figure 3 , Figure 5 and Figure 8 In a preferred embodiment, the transmission mechanism 7 includes a sliding frame 701 slidably connected to the outer surface of the sliding column 403, a connecting rod 702 connected to the lower end of the sliding frame 701, a second arc-shaped clamping plate 705 connected to the lower end of the connecting rod 702, a scraper 704 provided on the right side of the sliding frame 701, the transmission mechanism 7 also includes a door frame assembly 703 installed at the lower end of the moving groove 102, and the second drive mechanism 5 includes a first motor 501 installed on the upper right side of the device body 101, a rotating shaft 502 connected to the output end of the first motor 501, and a pull rope 503 wound around the outer surface of the rotating shaft 502;

[0056] In this embodiment: During the downward displacement of the inclined platform 604 by the weight of the soil, the connecting rod 702 connected to the upper right side of the inclined platform 604 drives the sliding frame 701 to move downward along the sliding column 403, thereby enabling the scraper 704 to scrape the surface of the filter bag 402, thus reducing soil blockage. Simultaneously with the downward displacement of the connecting rod 702, the second arc-shaped locking plate 705 connected to the right side of the connecting rod 702 interacts with the door frame assembly 703 to achieve a locking state. After the sensor 605 at the lower end of the inclined platform 604 contacts the sensing plate 603 and issues an alarm, the first motor 501 automatically starts, driving the rotating shaft 502 to rotate slowly, tightening the pull rope 503, and then... 503 slowly rewinds, causing the other end of the pull rope 503 to pull the sliding frame 701 upward along the sliding column 403. The scraper 704 performs a secondary scraping on the surface of the filter bag 402. At the same time, the lower connecting rod 702 of the sliding frame 701 moves upward. Since the second arc-shaped clamping plate 705 is engaged with the door frame assembly 703, the second arc-shaped clamping plate 705 pushes the door frame assembly 703 upward along the moving groove 102, thereby opening the device body 101, discharging the soil, and resetting the support inclined platform 604. After the first motor 501 completes its drive, it performs a reset rotation, ensuring that the pull rope 503 remains loose, thus ensuring that the sliding frame 701 can move downward when the support inclined platform 604 moves downward.

[0057] The sensor 605 and sensor 603 can also be replaced with a pressure sensor, which can be used in conjunction with the controller and alarm 606 to perform alarm operation.

[0058] In the previous embodiment, considering the need for an engagement between the second arc-shaped card plate 705 and the door frame assembly 703, and the issue of closing the door frame assembly 703, the specific operation is as follows:

[0059] Reference Figure 3 , Figure 6 and Figure 8 In a preferred embodiment, the door frame assembly 703 includes a movable door 7030 slidably connected inside the movable groove 102. A second spring 7031 is connected to the front and rear ends of the upper part of the movable door 7030. A slider 7033 is slidably connected to the front and rear ends of the left side of the movable door 7030. A third spring 7032 is connected to the right side of the slider 7033. A first arc-shaped plate 7035 is connected to the left side of the slider 7033. A wedge-shaped groove 7034 is provided at the upper end of the slider 7033. A wedge-shaped block 706 is provided at the upper end of the first groove 103. The wedge-shaped groove 7034 and the wedge-shaped block 706 are fitted together. The outer shell assembly 1 includes a device body 101. A movable groove 102 is provided at the lower end of the left side of the device body 101. A first groove 103 is provided at the front and rear ends of the left side of the movable groove 102.

[0060] In this embodiment: during the downward displacement of the second arc-shaped plate 705, the arc surface on the lower right side of the second arc-shaped plate 705 contacts the arc surface of the first arc-shaped plate 7035. The downward pressure of the second arc-shaped plate 705 causes the slider 7033 to slide into the moving door 7030, causing the second spring 7031 to contract. After the second arc-shaped plate 705 continues to move downward, it intersects with the first arc-shaped plate 7035. The second spring 7031 then pops the first arc-shaped plate 7035 back to its original position, thus achieving engagement between the second arc-shaped plate 705 and the first arc-shaped plate 7035. When the second arc-shaped plate 705 moves upward, it pushes the first arc-shaped plate 7035, causing the moving door 7030 to move upward along the moving groove 102, and the slider 7033... As the slider moves upward along the first slide groove 103, the second spring 7031 inside the moving groove 102 contracts under the pressure of the moving door 7030. At this time, the moving door 7030 opens, and the soil is discharged from the inside. When the slider 7033 reaches the upper position of the first slide groove 103, the wedge groove 7034 on the slider 7033 slowly engages with the wedge block 706 at the upper end of the first slide groove 103. During the engagement process, due to the misalignment, the wedge groove 7034 does not engage with the wedge block 706. The slider 7033 slides to the right, and the wedge groove 7034 and the wedge block 706 are perfectly engaged. As a result, the first arc-shaped locking plate 7035 and the second arc-shaped locking plate 705 on the left side of the slider 7033 disengage. The compressed second spring 7031 pops the moving door 7030 back to its original position, thereby closing the inside of the device body 101, allowing the soil to continue to accumulate.

[0061] In the previous embodiment, considering the slow speed inside the soil removal device body 101, the specific operation is as follows:

[0062] Reference Figure 2 , Figure 3 and Figure 8 In a preferred embodiment, a partition plate 9 is provided in the middle of the device body 101, and a second motor 10 is installed at the lower rear end of the device body 101. The output end of the second motor 10 is connected to a mud-removing plate 11, and brushes 12 are provided at both ends of the upper end of the mud-removing plate 11.

[0063] In this embodiment: when the movable door 7030 is opened, due to the partition plate 9 separating the upper and lower layers, the amount of soil in the lower layer of the device body 101 increases, the support inclined platform 604 rises and resets, the internal pressure of the device body 101 increases, and the soil is discharged outward under the action of internal pressure the moment the movable door 7030 is opened. At the same time, the upper surface of the support inclined platform 604 is set as an inclined surface to facilitate the flow of soil to the outlet, and the second motor 10 is automatically driven to drive the mud-pushing plate 11 to push the soil outward, increasing the discharge speed. The brush 12 on the mud-pushing plate 11 cleans the dead corners to prevent the soil from accumulating at the outlet.

[0064] Working Principle: During the drainage process of the foundation pit, water is first pumped out of the pit by the driven water pump 8. The muddy water in the pit enters from the left side of the outer shell assembly 1. At this time, the first drive mechanism 2 is activated, causing one of the two sets of channels inside the mud-water separation mechanism 3 to be closed and the other to be unobstructed. At the same time, the filter mechanism 4 blocks the mud in the muddy water. The filtered water is discharged from the right side of the outer shell assembly 1, thus ensuring that the mud accumulates in the channel. Soil discharge is carried out during the channel closure process, thereby reducing the blockage phenomenon that may occur in the subsequent discharge process. The discharged mud enters the lower end of the outer shell assembly 1 and falls on the alarm mechanism 6. The mud gradually accumulates, and the weight of the mud acts on the alarm mechanism 6, thereby triggering an alarm. The second drive mechanism 5 is automatically driven to drive the transmission mechanism 7 to discharge the mud. The automatic drive method with alarm prompts realizes the intelligent effect of the equipment. At the same time, each alarm issued by the alarm mechanism 6 is a mud discharge. The number of mud discharges is monitored and recorded through the BIM 3D model, thereby realizing the approximate calculation of the mud discharge volume, which facilitates the metering and collection of mud for subsequent support of the foundation pit or other uses.

[0065] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
