Description

Technical Field

[0001] The present invention relates to the technical field of foundation pit drainage, and specifically to a foundation pit drainage device for green buildings. Background Art

[0002] A building foundation pit is a temporary pit dug for building a foundation. The foundation pit belongs to a temporary project, and its function is to provide a space for the masonry operation of the foundation to be carried out at the designated position according to the design.

[0003] For example, a new drainage device applied to a building foundation pit for the renovation of old communities with the publication number of CN112647523A filters impurities such as branches and stones inside the foundation pit through a transparent spherical structure of a screen, preventing blockage inside the water accumulation sleeve and the drain pipe, so that the accumulated water inside the foundation pit enters the water collection sleeve through the screen and then flows into the drain pipe for discharge. By pressing down the fixing rod, the two fixing columns slide downward into the interior of the water collection sleeve, driving the gear meshed with the fixing column to rotate, making the two rotating shafts rotate to drive the screen to rotate inside the water collection sleeve. After the screen rotates, it rubs against the inner side wall of the top of the water collection sleeve, scraping off the branches and mud attached to the surface of the screen through the friction of the inner side wall of the water collection sleeve, improving the filtering effect of the screen and facilitating the drainage inside the foundation pit. After the screen rotates, the top column rotates away from the support block, causing the torsion spring to contract and generate elastic force, making the top column abut against the outer side wall of the screen. After the screen rotates and the support block is again located at the position of the top column, the elastic force of the torsion spring drives the top column to rotate into the interior of the support block, hitting the support block, vibrating the screen, and shaking off the mud attached to the screen, further enabling the screen to better filter and intercept branches and mud for the drainage of the foundation pit. However, in actual use, during the construction of green buildings in rural areas, temporary foundation pits are usually dug. The accumulated water in the foundation pit mainly comes from underground seepage or rainwater. During the process of pumping and draining the accumulated water, if the accumulated water stays in the foundation pit for a long time, it will soften the inner wall of the foundation pit. When there is no pumping, the accumulated water can support the inner wall of the foundation pit. However, during the pumping process, as the liquid level of the accumulated water drops, the inner wall of the foundation pit loses its support, and the soft soil on the inner wall may collapse. During the pumping process, the inner wall of the foundation pit cannot be monitored. Therefore, if the pumping is not stopped in time or the pumping speed is not reduced, the degree of collapse is likely to increase, easily causing irreversible damage to the foundation pit and affecting the subsequent use of the foundation pit, with certain usage defects.

[0004] Therefore, we propose a foundation pit drainage device for green buildings to solve the problems raised above. Summary of the Invention

[0005] The purpose of the present invention is to provide a foundation pit drainage device for green buildings, so as to solve the problems raised in the above-mentioned background technology. During the pumping process, as the water level of the accumulated water drops, the inner wall of the foundation pit loses its supporting effect, and the soft soil on the inner wall may collapse. During the pumping process, the inner wall of the foundation pit cannot be monitored. Therefore, if the pumping is not stopped in time or the pumping speed is not reduced, the degree of collapse is likely to increase, which is likely to cause irreversible damage to the foundation pit and affect the subsequent use of the foundation pit.

[0006] To achieve the above purpose, the present invention provides the following technical solutions: A foundation pit drainage device for green buildings includes a vehicle body. One side of the top of the vehicle body is fixedly installed with a water pump, and the water outlet end of the water pump is connected through a drain pipe, and the water pumping end of the water pump is connected through a water suction pipe. It further includes: A floating plate, fixedly installed on the side of the water suction pipe away from the water pump. A support assembly, arranged on one side of the outside of the water suction pipe. The support assembly includes a telescopic rod. A filtering assembly, arranged at the end of the water suction pipe away from the water pump. The telescopic rod is arranged on the upper side of the floating plate. One side of the inside of the telescopic rod is threadedly connected with a positioning bolt, and both ends of the telescopic rod are fixedly installed with fixing plates. On the side of the two fixing plates away from each other, fixing rods are symmetrically installed. At the same time, on the outside of the two fixing rods, a fixing frame is slidably connected. Moreover, on the side of the two fixing frames away from each other, two support plates are respectively fixedly installed. A telescopic spring is sleeved on the outside of the two groups of fixing rods. One end of the telescopic spring is fixedly connected with the fixing frame, and the other end of the telescopic spring is fixedly installed with a fixing block, and the fixing block is fixedly connected with the fixing rod.

[0007] Preferably, a rotating rod is rotatably connected to the outside of the telescopic rod. The end of the rotating rod away from the telescopic rod is fixedly installed with a guide sleeve, and the bottom end of the water suction pipe passes through the guide sleeve. At the same time, a plurality of rubber strips are fixedly installed circumferentially on the inner side of the guide sleeve.

[0008] By adopting the above technical solution, the rotation of the guide sleeve can lift the water suction pipe.

[0009] Preferably, mounting plates are symmetrically installed on both sides of the telescopic rod where the rotating rod is located. On one side between the two mounting plates, a limiting frame is fixedly installed, and the rotating rod is rotatably connected with the limiting frame. At the same time, rotating sleeves are symmetrically installed on the outside of the rotating rod. Moreover, on the outside of the two rotating sleeves, positioning frames are fixedly installed, and the positioning frames are fixedly connected with the two mounting plates.

[0010] By adopting the above technical solution, the rotation of the rotating rod and the rotating sleeve is supported.

[0011] Preferably, on one side below the outer part of each of the two rotating sleeves, a connecting block is fixedly installed, and on one side of the connecting block, a steel wire rope is fixedly installed. Moreover, on the top of each of the two fixing plates, a mounting bracket is fixedly installed, and at the same time, the end of the steel wire rope away from the connecting block is fixedly connected to the mounting bracket.

[0012] By adopting the above technical solution, the movement of the steel wire rope can drive the rotation of the rotating sleeve.

[0013] Preferably, on one side of the top of each of the two fixing brackets, a moving bracket is symmetrically installed, and between the two moving brackets, a roller is rotatably connected on one side. Moreover, a guide wheel is rotatably connected below the inner side of the mounting bracket. At the same time, both the roller and the guide wheel are rotatably connected to the steel wire rope.

[0014] By adopting the above technical solution, the movement of the fixing bracket can cause the steel wire rope to bend.

[0015] Preferably, on one side inside the two rotating sleeves, a movable rod is slidably connected, and on one side of the movable rod, a slope is formed. Moreover, on the outer side of the movable rod, a return spring is sleeved, and at the same time, one end of the return spring is fixedly connected to the rotating sleeve. Furthermore, at the other end of the rotating sleeve, a mounting block is fixedly installed, and the mounting block is fixedly connected to the movable rod.

[0016] By adopting the above technical solution, the movable rod can automatically return to its original position after moving.

[0017] Preferably, on one side inside the two rotating sleeves located outside the rotating rod, a plurality of connecting grooves are formed, and the movable rod abuts against the connecting grooves. Moreover, the slopes of the two movable rods are in opposite directions to the two sets of connecting grooves.

[0018] By adopting the above technical solution, it is avoided that when one side collapses, the two support plates move simultaneously.

[0019] Preferably, the filtering assembly includes a filter net fixedly installed at one end of the water suction pipe away from the water suction pump. Moreover, inside the water suction pipe above the filter net, a support rod is fixedly installed, and inside the support rod, a rotating shaft is rotatably connected. At the same time, the rotating shaft is rotatably connected to the filter net. Furthermore, above the rotating shaft, two sets of rotating blades are axially symmetrically installed.

[0020] By adopting the above technical solution, impurities in the accumulated water can be filtered during the water pumping operation.

[0021] Preferably, one end of the rotating shaft passes through the filter net and symmetrically installs cleaning rods on the outside, and the inner sides of the two cleaning rods are in contact with the filter net.

[0022] By adopting the above technical solution, the outside of the filter net can be cleaned during the water pumping process.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: The foundation pit drainage device for green buildings enables the inner wall of the foundation pit to be supported when pumping water from the foundation pit. Once a collapse occurs inside the foundation pit, the pumping work can be slowed down or stopped, avoiding further pumping that may lead to a decrease in the supporting force of the inner wall of the foundation pit and causing a larger collapse, thus preventing the impact on the subsequent use of the foundation pit and enhancing the practicality; 1. When draining water from the foundation pit, abut the two support plates against both sides of the inner wall of the foundation pit. Then, the positioning bolts can be tightened to fix the length of the telescopic rod. After that, start the water pump, and the water suction pipe can pump water from the foundation pit. The water suction pipe can float on the water surface through the floating plate. As the water level drops, the water suction pipe descends, and the water suction pipe can slide in the guide sleeve. The guide sleeve can guide the movement of the water suction pipe. During the pumping process, if a collapse occurs on both sides of the inner wall of the foundation pit, it can directly push the support plate to move. After the support plate moves, it drives the fixed frame to move, so that the fixed frame can slide on the fixed rod and stretch the telescopic spring. When the fixed frame moves, it drives the rollers between the movable frames to move. After the rollers move, they can push the steel wire rope to bend. Since one end of the steel wire rope is fixed to the mounting frame, after the steel wire rope bends, it can pull the rotating sleeve to rotate through the connecting block. After the rotating sleeve rotates, it can drive the rotating rod to rotate. After the rotating rod rotates, it can drive the guide sleeve to rotate. After the guide sleeve rotates, the rubber strip inside abuts against the water suction pipe and lifts the water suction pipe. The water suction pipe is specifically a steel wire plastic pipe and will not easily bend, which can make the water suction end of the water suction pipe move upward, all or partially away from the accumulated water. Therefore, when a collapse occurs on the inner wall of the foundation pit, the pumping work can be slowed down in time. At this time, the staff can observe the degree of collapse of the inner wall of the foundation pit. If the degree of collapse is small, the position of the support plate in the foundation pit can be changed, and the pumping operation can continue. If the degree of collapse of the foundation pit is large, the staff can stop the pumping work and support the foundation pit by increasing the support or re-injecting the accumulated water to avoid further collapse of the foundation pit. Moreover, during the pumping work, the water suction pipe can be prevented from contacting the inner wall of the foundation pit, avoiding the blockage of the water suction pipe caused by the sediment on the inner wall. Through the support assembly, when pumping water from the foundation pit, the inner wall of the foundation pit can be supported. Once a collapse occurs inside the foundation pit, the pumping work can be slowed down or stopped, avoiding further pumping that may lead to a decrease in the supporting force of the inner wall of the foundation pit and causing a larger collapse, thus preventing the impact on the subsequent use of the foundation pit and enhancing the practicality; 2. When the foundation pit collapses, if it collapses on one side, the bending of the wire rope on one side can drive the rotation of the rotating sleeve on one side. During the rotation of the rotating sleeve, one side of the movable rod abuts against the inner wall of the connecting groove, causing the rotation of the rotating sleeve to drive the rotation of the rotating rod. After the rotation of the rotating rod, the connecting groove on the other side can contact the slope of the movable rod, causing the rotation of the rotating rod to push the movable rod to move and stretch the return spring. As a result, when one side of the rotating sleeve drives the rotation of the rotating rod, it will not drive the rotation of the rotating sleeve on the other side, preventing the movement of the support plate on the other side. If the support plates on both sides move simultaneously, the rotating rod can also rotate, enabling the detection of the inner wall of the foundation pit during the pumping process. Regardless of which side of the inner wall of the foundation pit collapses, the pumping work can be slowed down or stopped. 3. During the pumping operation, the accumulated water enters the interior of the water suction pipe through the filter screen. The filter screen can filter impurities in the accumulated water. After the accumulated water enters the water suction pipe, it can directly impact the rotating blades. The impact of the water flow on the rotating blades can drive the rotation of the rotating shaft. After the rotation of the rotating shaft, it can drive the rotation of the cleaning rod. After the rotation of the cleaning rod, it can clean the impurities outside the filter screen, preventing the attachment of impurities to the outside of the filter screen due to pumping, avoiding affecting the pumping efficiency, and enhancing the practicality.

[0027] Please refer to Figures 1 - 9 , the present invention provides a technical solution: a foundation pit drainage device for green buildings, including a vehicle body 1, a water pump 101 is fixedly installed on one side of the top of the vehicle body 1, and the water outlet end of the water pump 101 is connected through a drain pipe 102, and the water suction end of the water pump 101 is connected through a water suction pipe 103; It also includes: A floating plate 1031, fixedly installed on the outer side of the water suction pipe 103 away from the water pump 101; A support assembly 2, arranged on the outer side of the water suction pipe 103, and the support assembly 2 includes a telescopic rod 201; The telescopic rod 201 is arranged on the upper side of the floating plate 1031, a positioning bolt 202 is threadedly connected to the inner side of the telescopic rod 201, and fixed plates 203 are fixedly installed at both ends of the telescopic rod 201, and fixed rods 204 are symmetrically installed on the outer sides of the two fixed plates 203 away from each other. At the same time, a fixed frame 205 is slidably connected to the outer side of the two fixed rods 204, and two support plates 208 are fixedly installed on the outer sides of the two fixed frames 205 away from each other; The telescopic spring 206 is sleeved on the outer side of the two groups of fixed rods 204, one end of the telescopic spring 206 is fixedly connected to the fixed frame 205, and the other end of the telescopic spring 206 is fixedly installed with a fixed block 207, and the fixed block 207 is fixedly connected to the fixed rod 204; One side of the outside of the telescopic rod 201 is rotatably connected with a rotating rod 209, and a guide sleeve 210 is fixedly installed at one end of the rotating rod 209 away from the telescopic rod 201. The bottom end of the water suction pipe 103 passes through the guide sleeve 210, and a plurality of rubber strips are fixedly installed circumferentially on the inner side of the guide sleeve 210; Mounting plates 211 are symmetrically installed on both sides of the telescopic rod 201 where the rotating rod 209 is located. A limiting frame 212 is fixedly installed on one side between the two mounting plates 211, and the rotating rod 209 is rotatably connected with the limiting frame 212. Rotating sleeves 213 are symmetrically installed on one side of the outside of the rotating rod 209. Positioning frames 214 are fixedly installed on the outside of both rotating sleeves 213, and the positioning frames 214 are fixedly connected with the two mounting plates 211; Connecting blocks 215 are fixedly installed on one side below the outside of both rotating sleeves 213. A steel wire rope 216 is fixedly installed on one side of the connecting block 215. Mounting frames 217 are fixedly installed on the tops of both fixing plates 203. One end of the steel wire rope 216 away from the connecting block 215 is fixedly connected with the mounting frame 217; Moving frames 218 are symmetrically installed on one side of the tops of both fixing frames 205. A roller 219 is rotatably connected on one side between the two moving frames 218. A guide wheel 220 is rotatably connected below the inner side of the mounting frame 217. Both the roller 219 and the guide wheel 220 are rotatably connected with the steel wire rope 216.

[0028] Example 1: As Figures 1 - 7As shown in the figure, when draining water from the foundation pit, two support plates 208 are abutted against the inner walls on both sides of the foundation pit. Then, the positioning bolts 202 can be tightened to fix the length of the telescopic rod 201. After that, the water pump 101 is started, and the water extraction pipe 103 can be used to pump water from the foundation pit. The water extraction pipe 103 can float on the water surface through the floating plate 1031. As the water level drops, the water extraction pipe 103 descends, and the water extraction pipe 103 can slide in the guide sleeve 210. The guide sleeve 210 can guide the movement of the water extraction pipe 103. During the water extraction process, if the inner walls on both sides of the foundation pit collapse, the support plate 208 can be directly pushed to move. After the support plate 208 moves, it drives the fixed frame 205 to move, so that the fixed frame 205 can slide on the fixed rod 204 and stretch the telescopic spring 206. When the fixed frame 205 moves, it drives the rollers 219 between the moving frames 218 to move. After the rollers 219 move, they can push the steel wire rope 216 to bend. Since one end of the steel wire rope 216 is fixed to the mounting frame 217, after the steel wire rope 216 bends, it can pull the rotating sleeve 213 to rotate through the connecting block 215. After the rotating sleeve 213 rotates, it can drive the rotating rod 209 to rotate. After the rotating rod 209 rotates, it can drive the guide sleeve 210 to rotate. After the guide sleeve 210 rotates, the rubber strip inside abuts against the water extraction pipe 103 to lift the water extraction pipe 103. After the rubber strip abuts against the water extraction pipe 103, the friction force can be used to prevent the water extraction pipe 103 from falling easily. After the guide sleeve 210 rotates, the angle of the water extraction pipe 103 inside continuously increases, and the water extraction pipe 103 is not easily dented. The water extraction pipe 103 can be lifted by the rotation of the guide sleeve 210. The water extraction pipe 103 is specifically a steel wire plastic pipe and is not easily bent, which can make the water extraction end of the water extraction pipe 103 move upward and all or partially leave the accumulated water. Therefore, when the inner wall of the foundation pit collapses, the water extraction work can be slowed down in time. At this time, the staff can observe the degree of collapse of the inner wall of the foundation pit. If the degree of collapse is small, the position of the support plate 208 in the foundation pit can be changed, and the water extraction operation can continue. If the degree of collapse of the foundation pit is large, the staff can stop the water extraction work and support the foundation pit by increasing the support or re-injecting the accumulated water to prevent the foundation pit from continuing to collapse. Moreover, during the water extraction work, the water extraction pipe 103 can be prevented from contacting the inner wall of the foundation pit to avoid the sediment on the inner wall from blocking the water extraction pipe 103. Through the support assembly 2, when draining water from the foundation pit, the inner wall of the foundation pit can be supported. Once a collapse occurs inside the foundation pit, the water extraction work can be slowed down or stopped to avoid further water extraction leading to a decrease in the supporting force of the inner wall of the foundation pit and causing a greater collapse, thus avoiding affecting the subsequent use of the foundation pit and improving the practicability.

[0029] On one side inside each of the two rotating sleeves 213, a movable rod 221 is slidably connected. A slope is provided on one side of the movable rod 221. A return spring 222 is sleeved on the outer side of the movable rod 221. One end of the return spring 222 is fixedly connected to the rotating sleeve 213. At the other end of the rotating sleeve 213, a mounting block 223 is fixedly installed, and the mounting block 223 is fixedly connected to the movable rod 221; On one side inside the two rotating sleeves 213 on the outer side of the rotating rod 209, a number of connecting grooves 224 are provided. The movable rod 221 abuts against the connecting grooves 224. The slopes of the two movable rods 221 are in opposite directions to the two groups of connecting grooves 224.

[0030] Embodiment 2: As Figures 5 - 8 shown, when the foundation pit collapses, if it collapses on one side, the bending of the steel wire rope 216 on one side can pull the rotating sleeve 213 on one side to rotate. During the rotation of the rotating sleeve 213, one side of the movable rod 221 abuts against the inner wall of the connecting groove 224, so that the rotation of the rotating sleeve 213 drives the rotating rod 209 to rotate. After the rotating rod 209 rotates, the connecting groove 224 on the other side can contact the slope of the movable rod 221, so that the rotation of the rotating rod 209 can push the movable rod 221 to move and stretch the return spring 222. Furthermore, after the rotating sleeve 213 on one side drives the rotating rod 209 to rotate, it will not drive the rotating sleeve 213 on the other side to rotate, avoiding driving the support plate 208 on the other side to move. If the support plates 208 on both sides move at the same time, the rotating rod 209 can also rotate, so that the inner wall of the foundation pit can be detected during the pumping process. No matter which side of the inner wall of the foundation pit collapses, the pumping work can be slowed down or stopped.

[0031] The filtering assembly 3 is arranged at one end of the water suction pipe 103 away from the water suction pump 101; The filtering assembly 3 includes a filter net 301 fixedly installed at one end of the water suction pipe 103 away from the water suction pump 101. Inside the water suction pipe 103 and above the filter net 301, a support rod 302 is fixedly installed. A rotating shaft 303 is rotatably connected inside the support rod 302. The rotating shaft 303 is rotatably connected to the filter net 301. Above the outer side of the rotating shaft 303, two groups of rotating blades 304 are axially symmetrically installed (the rotating blades 304 are centrally symmetrically installed above the outer side of the rotating shaft 303); One end of the rotating shaft 303 passes through the filter net 301 and cleaning rods 305 are symmetrically installed on the outside. The inner sides of the two cleaning rods 305 are attached to the filter net 301.

[0032] Embodiment 3: As Figures 1 - 2 and Figure 9As shown, when pumping water, the accumulated water enters the inside of the water suction pipe 103 through the filter screen 301. The filter screen 301 can filter impurities in the accumulated water. After the accumulated water enters the water suction pipe 103, it can directly impact the rotating blade 304. The flowing water can drive the rotating shaft 303 to rotate by impacting the rotating blade 304. After the rotating shaft 303 rotates, it can drive the cleaning rod 305 to rotate. After the cleaning rod 305 rotates, it can clean the impurities outside the filter screen 301, avoiding the attachment of impurities to the outside of the filter screen 301 due to pumping, preventing the influence on the pumping efficiency, and improving the practicability.

[0033] Working principle: When using the foundation pit drainage device for green buildings, first, according to Figures 1 - 9 As shown, when draining water from the foundation pit, abut the two support plates 208 against both sides of the inner wall of the foundation pit. Then, tighten the positioning bolts 202 to fix the length of the telescopic rod 201. After that, start the water pump 101, and the water suction pipe 103 can pump water from the foundation pit. The water suction pipe 103 can float on the water surface through the floating plate 1031. As the water level drops, the water suction pipe 103 descends, and the water suction pipe 103 can slide in the guide sleeve 210. The guide sleeve 210 can guide the movement of the water suction pipe 103. During the pumping process, if the inner walls on both sides of the foundation pit collapse, it can directly push the support plate 208 to move. After the support plate 208 moves, it drives the fixed frame 205 to move, so that the fixed frame 205 can slide on the fixed rod 204 and stretch the telescopic spring 206. When the fixed frame 205 moves, it drives the rollers 219 between the moving frames 218 to move. After the rollers 219 move, they can push the steel wire rope 216 to bend. Since one end of the steel wire rope 216 is fixed to the mounting frame 217, after the steel wire rope 216 bends, it can pull the rotating sleeve 213 to rotate through the connecting block 215. After the rotating sleeve 213 rotates, it can drive the rotating rod 209 to rotate. After the rotating rod 209 rotates, it can drive the guide sleeve 210 to rotate. After the guide sleeve 210 rotates, the rubber strip inside abuts against the water suction pipe 103 to lift the water suction pipe 103. The water suction pipe 103 is specifically a steel wire plastic pipe and is not easily bent, which can make the pumping end of the water suction pipe 103 move upward, completely or partially away from the accumulated water. Thus, when the inner wall of the foundation pit collapses, the pumping work can be slowed down in time. At this time, the staff can observe the degree of collapse of the inner wall of the foundation pit. If the degree of collapse is small, the position of the support plate 208 in the foundation pit can be changed, and the pumping operation can continue. If the degree of collapse of the foundation pit is large, the staff can stop the pumping work and support the foundation pit by increasing the support or re-injecting the accumulated water to avoid the continuous collapse of the foundation pit. Moreover, during the pumping work, the water suction pipe 103 can be prevented from contacting the inner wall of the foundation pit, avoiding the blockage of the water suction pipe 103 caused by the sediment on the inner wall; When the foundation pit collapses, if it collapses on one side, the bending of the wire rope 216 on one side can drive the rotation of the rotating sleeve 213 on one side. During the rotation of the rotating sleeve 213, one side of the movable rod 221 abuts against the inner wall of the connecting groove 224, so that the rotation of the rotating sleeve 213 drives the rotation of the rotating rod 209. After the rotation of the rotating rod 209, the connecting groove 224 on the other side can contact the slope of the movable rod 221, so that the rotation of the rotating rod 209 can push the movable rod 221 to move and stretch the return spring 222. Furthermore, after the rotating sleeve 213 on one side drives the rotation of the rotating rod 209, it will not drive the rotation of the rotating sleeve 213 on the other side, avoiding driving the movement of the supporting plate 208 on the other side. If the supporting plates 208 on both sides move simultaneously, it can also make the rotating rod 209 rotate. When pumping water, the accumulated water enters the inside of the water suction pipe 103 through the filter screen 301, and the impurities in the accumulated water can be filtered by the filter screen 301. After the accumulated water enters the water suction pipe 103, it can directly impact the rotating blade 304, and the rotation of the rotating shaft 303 can be driven by the impact of the water flow on the rotating blade 304.
