Description

Technical Field

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

[0002] A construction foundation pit is a temporary pit excavated for the building foundation. The foundation pit is a temporary project and its function is to provide a space so that the foundation masonry work can be carried out in the position specified by the design.

[0003] The utility model discloses a novel drainage device for use in the renovation of the building foundation pit of an old community, which uses a transparent spherical structure of the gauze to filter impurities such as branches and stones inside the foundation pit, thereby preventing the water accumulation sleeve and the drainage pipe from being blocked. The water accumulated in the foundation pit enters the water collection sleeve through the gauze and flows into the drainage pipe for discharge. By pressing the fixing rod downward, the two fixing columns slide downward into the interior of the water collection sleeve, driving the gear meshed with the fixing column to rotate, so that the two rotating shafts rotate and drive the gauze to rotate inside the water collection sleeve. After the gauze rotates, it rubs against the inner side wall of the top of the water collection sleeve, so that the branches and mud attached to the surface of the gauze are scraped off by the friction of the inner side wall of the water collection sleeve, thereby improving the filtering effect of the gauze, and facilitating the drainage of the foundation pit. After the gauze rotates, the top column rotates away from the support block, causing the torsion spring to contract and generate elastic force, causing the top column to hit the outer wall of the gauze. After the gauze rotates and the support block is located at the top column position again, The elastic force of the torsion spring drives the top column to rotate into the interior of the support block, impacting the support block, causing the mesh to vibrate, shaking off the soil attached to the mesh, and further enabling the mesh to better filter and intercept branches and soil, and drain the foundation pit. However, in actual use, in the construction of green buildings in townships, temporary foundation pits are usually dug. The accumulated water in the foundation pit mainly comes from underground seepage or rainwater. In the process of extracting 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 the water is not pumped out, the accumulated water can support the inner wall of the foundation pit. During the pumping process, as the liquid 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. The inner wall of the foundation pit cannot be monitored during the pumping process. If the pumping is not stopped in time or the pumping speed is not reduced, the degree of collapse is likely to increase, which may cause irreversible damage to the foundation pit, affect the subsequent use of the foundation pit, and have certain usage defects.

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

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

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a foundation pit drainage device for green buildings, comprising a vehicle body, a water pump fixedly mounted on one side of the top of the vehicle body, a drainage pipe being connected through the water outlet end of the water pump, and a water pumping pipe being connected through the water pumping end of the water pump;

[0015] Preferably, the telescopic rod is symmetrically installed with mounting plates on both sides of the rotating rod, and a limit frame is fixedly installed on one side between the two mounting plates, and the rotating rod is rotatably connected to the limit frame. At the same time, a rotating sleeve is symmetrically installed on the outer side of the rotating rod, and a positioning frame is fixedly installed on the outer side of the two rotating sleeves, and the positioning frame is fixedly connected to the two mounting plates.

[0016] By adopting the above technical solution, the rotation of the rotating rod and the rotating sleeve is supported.

[0017] Preferably, a connecting block is fixedly installed on the lower side of the exterior of the two rotating sleeves, and a steel wire rope is fixedly installed on one side of the connecting block, and a mounting frame is fixedly installed on the top of the two fixed plates, and the end of the steel wire rope away from the connecting block is fixedly connected to the mounting frame.

[0018] By adopting the above technical solution, the movement of the wire rope can pull the rotating sleeve to rotate.

[0019] Preferably, a movable frame is symmetrically installed on one side of the top of the two fixed frames, and a roller is rotatably connected to one side between the two movable frames, and a guide wheel is rotatably connected to the inner lower side of the mounting frame, and the roller and the guide wheel are rotatably connected to the wire rope.

[0020] By adopting the above technical solution, the movement of the fixing frame can cause the steel wire rope to bend.

[0021] Preferably, the inner side of the two rotating sleeves are slidably connected to a movable rod, and a slope is provided on one side of the movable rod, and a return spring is provided on the outer side of the movable rod, and one end of the return spring is fixedly connected to the rotating sleeve, and the other end of the rotating sleeve is fixedly installed with a mounting block, and the mounting block is fixedly connected to the movable rod.

[0023] Preferably, a plurality of connection grooves are provided on one side of the outer portion of the rotating rod located inside the two rotating sleeves, and the movable rod abuts against the connection grooves, and the slopes of the two movable rods are in opposite directions to the two groups of connection grooves.

[0024] By adopting the above technical solution, collapse of one side is avoided and the two support plates move simultaneously.

[0025] Preferably, the filter assembly includes a filter screen fixedly mounted on one end of the water suction pipe away from the water pump, and a support rod is fixedly mounted inside the water suction pipe above the filter screen, and a rotating shaft is rotatably connected to the inside of the support rod, and the rotating shaft is rotatably connected to the filter screen, and two groups of rotating blades are axially symmetrically mounted above the outside of the rotating shaft.

[0026] By adopting the above technical solution, impurities in accumulated water can be filtered during pumping work.

[0027] Preferably, one end of the rotating shaft passes through the filter screen and cleaning rods are symmetrically installed on the outside, and the inner sides of the two cleaning rods are in contact with the filter screen.

[0028] By adopting the above technical solution, the outside of the filter screen can be cleaned during the water pumping process.

[0029] Compared with the prior art, the present invention has the following beneficial effects: the foundation pit drainage device for green buildings can support the inner wall of the foundation pit when pumping water out of the foundation pit. Once a collapse occurs inside the foundation pit, the pumping work can be slowed down or stopped, thereby avoiding further collapse caused by a reduction in the supporting force of the inner wall of the foundation pit due to continued pumping, thus avoiding affecting the subsequent use of the foundation pit and improving practicality.

[0030] When the water pump is started, the water pipe can be used to pump water from the foundation pit, and the water pipe can float on the water surface through the floating plate. As the water level drops, the water pipe can drop, and the water pipe can slide in the guide sleeve, and the water pipe can be guided to move by the guide sleeve. If the inner walls of the foundation pit collapse during the pumping process, the support plate can be directly pushed to move. After the support plate moves, the fixed frame can be driven to move, so that the fixed frame can slide on the fixed rod and stretch the telescopic spring. When the fixed frame moves, the rollers between the moving frames can be driven to move. After the rollers move, the wire rope can be bent. Since one end of the wire rope is fixed to the mounting frame, the wire rope can be rotated by pulling the rotating sleeve through the connecting block after bending. After the rotating sleeve rotates, the rotating rod can be driven to rotate. After the rotating rod rotates, the guide sleeve can be driven to rotate. When the foundation pit collapses, the water pumping work can be slowed down or stopped in time, so as to avoid that the supporting force of the inner wall of the foundation pit is reduced due to continued pumping and the use of subsequent foundation pits is affected, thereby improving the practicality.

[0031] 2. When the foundation pit collapses, if one side collapses, the bending of the steel wire rope on one side can pull the rotating sleeve on one side to rotate. During the rotation of the rotating sleeve, one side of the movable rod abuts against the inner wall of the connecting groove, so that the rotating sleeve rotates and drives the rotating rod to rotate. After the rotating rod rotates, the connecting groove on the other side can contact the slope of the movable rod, so that the rotation of the rotating rod can push the movable rod to move and stretch the reset spring, so that after the rotating sleeve on one side drives the rotating rod to rotate, it will not drive the rotating sleeve on the other side to rotate, avoiding driving the support plate on the other side to move. If the support plates on both sides move at the same time, the rotating rod can also be rotated, 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.

[0032] 3. When pumping water, the accumulated water enters the interior of the pumping pipe through the filter. The impurities in the accumulated water can be filtered through the filter. After entering the pumping pipe, the accumulated water can directly impact the rotating blades. The water flow can impact the rotating blades to drive the rotating shaft to rotate. After the rotating shaft rotates, it can drive the cleaning rod to rotate. After the cleaning rod rotates, it can clean the impurities outside the filter, avoiding impurities adhering to the outside of the filter due to extraction, avoiding affecting the pumping efficiency, and improving practicality.

DETAILED DESCRIPTION

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] See also Figures 1-9 The present invention provides a technical solution: a foundation pit drainage device for green buildings, comprising a vehicle body 1, a water pump 101 fixedly mounted on one side of the top of the vehicle body 1, a water outlet end of the water pump 101 being connected to a drainage pipe 102, and a water pumping end of the water pump 101 being connected to a water pumping pipe 103;

[0045] Also includes:

[0046] The floating plate 1031 is fixedly mounted on the outside of the water pumping pipe 103 on a side away from the water pump 101;

[0047] The support assembly 2 is provided on the outer side of the water pumping pipe 103 and includes a telescopic rod 201;

[0048] The telescopic rod 201 is arranged on one side above the floating plate 1031. A positioning bolt 202 is threadedly connected to the inner side of the telescopic rod 201. A fixing plate 203 is fixedly installed at both ends of the telescopic rod 201. A fixing rod 204 is symmetrically installed on the side away from the two fixing plates 203. At the same time, a fixing frame 205 is slidably connected to the outer side of the two fixing rods 204. Two support plates 208 are fixedly installed on the side away from the two fixing frames 205.

[0049] The telescopic spring 206 is sleeved on one side of the outside of the two sets of fixed rods 204. One end of the telescopic spring 206 is fixedly connected to the fixing frame 205, and the other end of the telescopic spring 206 is fixedly mounted with a fixing block 207, and the fixing block 207 is fixedly connected to the fixed rod 204.

[0050] The outer side of the telescopic rod 201 is rotatably connected to a rotating rod 209, and a guide sleeve 210 is fixedly installed on the end of the rotating rod 209 away from the telescopic rod 201. The bottom end of the water extraction pipe 103 passes through the guide sleeve 210. At the same time, a number of rubber strips are fixedly installed on the inner circumference of the guide sleeve 210.

[0051] The telescopic rod 201 is symmetrically mounted with mounting plates 211 on both sides of the rotating rod 209, and a limit frame 212 is fixedly mounted on one side between the two mounting plates 211. The rotating rod 209 is rotatably connected to the limit frame 212. At the same time, a rotating sleeve 213 is symmetrically mounted on the outer side of the rotating rod 209, and a positioning frame 214 is fixedly mounted on the outer side of each rotating sleeve 213. The positioning frame 214 is fixedly connected to the two mounting plates 211.

[0052] A connecting block 215 is fixedly mounted on one side of the outer lower portion of each rotating sleeve 213, and a steel wire rope 216 is fixedly mounted on one side of the connecting block 215. A mounting bracket 217 is fixedly mounted on the top of each of the two fixed plates 203, and one end of the steel wire rope 216 away from the connecting block 215 is fixedly connected to the mounting bracket 217.

[0053] A movable frame 218 is symmetrically installed on one side of the top of the two fixed frames 205, and a roller 219 is rotatably connected to one side between the two movable frames 218, and a guide wheel 220 is rotatably connected to the inner lower side of the mounting frame 217. At the same time, the roller 219 and the guide wheel 220 are both rotatably connected to the wire rope 216.

[0054] Example 1: Figure 1-Figure 7As shown, when draining the foundation pit, the two support plates 208 are brought into contact with both sides of the inner wall of the foundation pit, and then the positioning bolts 202 can be tightened to fix the length of the telescopic rod 201, and then the water pump 101 is started to pump water from the foundation pit through the water pipe 103. The water pipe 103 can float on the water surface through the floating plate 1031, and as the water level drops, the water pipe 103 drops, and the water pipe 103 can slide in the guide sleeve 210, and the water pipe 103 can be guided to move by the guide sleeve 210. If the inner walls of the foundation pit collapse during the pumping process, the support plates 208 can be directly pushed to move, and the support plates 208 can move. After that, the fixing frame 205 is driven to move, so that the fixing frame 205 can slide on the fixing rod 204 and stretch the telescopic spring 206. When the fixing frame 205 moves, the roller 219 between the moving frame 218 is driven to move. After the roller 219 moves, the wire rope 216 can be pushed to bend. Since one end of the wire rope 216 is fixed to the mounting frame 217, the wire rope 216 can be rotated by pulling the rotating sleeve 213 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 and the drawer are connected. The abutment of the water pipe 103 lifts the water pumping pipe 103. After the rubber strip abuts against the water pumping pipe 103, the friction force can be used to prevent the water pumping pipe 103 from falling easily. After the guide sleeve 210 rotates, the angle of the internal water pumping pipe 103 continues to increase, and the water pumping pipe 103 will not be easily concave. The water pumping pipe 103 can be lifted by rotating the guide sleeve 210. The water pumping pipe 103 is specifically a steel wire plastic pipe, which will not bend easily. The water pumping end of the water pumping pipe 103 can be moved up completely or partially to leave the accumulated water, and then 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 collapse degree of the inner wall of the foundation pit. If the collapse degree is small, the support plate can be changed. 208 At the position in the foundation pit, pumping operations can continue. If the foundation pit collapses significantly, the staff can stop pumping and use additional support or backfilling of accumulated water to support the foundation pit to prevent the foundation pit from continuing to collapse. During the pumping operation, the pumping pipe 103 can be prevented from contacting the inner wall of the foundation pit to prevent mud and sand on the inner wall from clogging the pumping pipe 103. The support assembly 2 can support the inner wall of the foundation pit when pumping and draining the foundation pit. Once collapse occurs inside the foundation pit, the pumping operation can be slowed down or stopped to avoid continued pumping, which will lead to a reduction in the supporting force of the inner wall of the foundation pit and cause a greater collapse, thereby avoiding affecting the subsequent use of the foundation pit and improving practicality.

[0055] A movable rod 221 is slidably connected to one side of each rotating sleeve 213, and 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, and a mounting block 223 is fixedly installed on the other end of the rotating sleeve 213. The mounting block 223 is fixedly connected to the movable rod 221.

[0056] A plurality of connection slots 224 are formed on the outer side of the rotating rod 209 located inside the two rotating sleeves 213 , and the movable rods 221 abut against the connection slots 224 , and the slopes of the two movable rods 221 are in opposite directions to the two groups of connection slots 224 .

[0057] Example 2: Figure 5-Figure 8 As shown, when the foundation pit collapses, if one side collapses, the steel wire rope 216 on one side bends to 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 rotating sleeve 213 rotates to drive 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 rotating rod 209 rotates to push the movable rod 221 to move and stretch the reset spring 222, so that 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, thereby 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 be rotated, 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.

[0058] The filter assembly 3 is arranged at one end of the water pump 103 away from the water pump 101;

[0059] The filter assembly 3 includes a filter screen 301 fixedly mounted on an end of the water pump 103 away from the water pump 101, and a support rod 302 fixedly mounted inside the water pump 103 above the filter screen 301. A rotating shaft 303 is rotatably connected to the support rod 302. The rotating shaft 303 is rotatably connected to the filter screen 301, and two groups of rotating blades 304 are axially symmetrically mounted above the outer portion of the rotating shaft 303 (the rotating blades 304 are symmetrically mounted on the outer portion of the rotating shaft 303).

[0060] One end of the rotating shaft 303 passes through the filter screen 301 and cleaning rods 305 are symmetrically installed on the outside, and the inner sides of the two cleaning rods 305 are in contact with the filter screen 301.

[0061] Example 3: Figure 1-Figure 2 and Figure 9As shown, during the pumping operation, the accumulated water enters the interior of the pumping pipe 103 through the filter 301, and the impurities in the accumulated water can be filtered through the filter 301. After the accumulated water enters the pumping pipe 103, it can directly impact the rotating blade 304, and the rotating shaft 303 can be driven to rotate by the impact of the water flow on 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 301, thereby avoiding impurities adhering to the outside of the filter 301 due to extraction, avoiding affecting the pumping efficiency, and improving practicality.

[0062] Working principle: When using the foundation pit drainage device for green buildings, first, according to Figures 1-9 As shown, when draining the foundation pit, the two support plates 208 are brought into contact with both sides of the inner wall of the foundation pit, and then the positioning bolts 202 can be tightened to fix the length of the telescopic rod 201. Then, the water pump 101 is started, and the water pumping pipe 103 can be used to pump water from the foundation pit. The water pumping pipe 103 can float on the water surface through the floating plate 1031. As the water level drops, the water pumping pipe 103 drops, and the water pumping pipe 103 can slide in the guide sleeve 210, and the guide sleeve 210 can be used to guide the water pumping pipe 103. If the inner walls of the foundation pit collapse during the pumping process, 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 roller 219 between the mobile frame 218 to move. After the roller 219 moves, it can push the wire rope 216 to bend. Since one end of the wire rope 216 is fixed to the mounting frame 217, the wire rope After the rope 216 is bent, it can pull the rotating sleeve 213 through the connecting block 215 to rotate. After the rotating sleeve 213 is rotated, it can drive the rotating rod 209 to rotate. After the rotating rod 209 is rotated, it can drive the guide sleeve 210 to rotate. After the guide sleeve 210 is rotated, the rubber strip inside the guide sleeve 210 abuts against the water pumping pipe 103 to lift the water pumping pipe 103. The water pumping pipe 103 is specifically a steel wire plastic pipe and will not bend easily. It can make the water pumping end of the water pumping pipe 103 move up completely or partially away from the accumulated water, thereby causing the inner wall of the foundation pit to collapse. When the foundation pit collapses, the pumping work can be slowed down in time. At this time, the staff can observe the collapse degree of the inner wall of the foundation pit. If the collapse degree is small, the position of the support plate 208 in the foundation pit can be changed, and the pumping operation can be continued. If the collapse degree of the foundation pit is large, the staff can stop the pumping work and adopt additional support or backfilling of the accumulated water to support the foundation pit to prevent the foundation pit from continuing to collapse. In addition, during the pumping work, the pumping pipe 103 can be prevented from contacting the inner wall of the foundation pit to prevent the mud and sand on the inner wall from clogging the pumping pipe 103.

[0063] When the foundation pit collapses, if one side collapses, the steel wire rope 216 on one side bends to 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 rotating sleeve 213 rotates to drive 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 rotating rod 209 rotates to push the movable rod 221 to move and stretch the reset spring 222, so that the rotating sleeve 213 on one side drives the rotating rod 209 to rotate without driving the rotating sleeve 213 on the other side to rotate. , to avoid 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 be rotated. When pumping water, the accumulated water enters the interior of the water pumping pipe 103 through the filter screen 301, and the impurities in the accumulated water can be filtered through the filter screen 301. After the accumulated water enters the water pumping pipe 103, it can directly impact the rotating blade 304, and the rotating blade 304 can be impacted by the water flow to drive the rotating shaft 303 to rotate. 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.
