Description

Technical Field

[0001] The invention relates to the technical field of foundation pit construction protection, and in particular to an intelligent environmental protection device suitable for foundation pit construction. Background Art

[0002] Foundation pit projects often require foundation pit covering measures to ensure the safety of buildings next to the foundation pit and properly manage the environment inside and outside the foundation pit. Materials such as plastic films have good air permeability and waterproof properties, which can effectively isolate the environment inside and outside the foundation pit, and play a role in heat preservation and moisture retention, reducing humidity and controlling soil moisture. At the same time, it can prevent soil erosion and damage to the concrete structure of the foundation pit to a certain extent, thereby ensuring construction quality and safety.

[0003] During the foundation pit covering operation, the membrane body needs to be properly covered on the top of the foundation pit and accurately positioned and installed at both ends. However, due to the large size of the membrane body, in order to ensure that it can withstand the accumulation of snow, an arch structure is usually used for laying. Although this method is effective, it greatly increases the complexity of construction, making the covering process particularly cumbersome and inconvenient for efficient operation. In addition, the single-layer membrane body performs poorly in terms of thermal insulation, especially in extreme climatic conditions, its protective performance is greatly reduced, and it is difficult to fully guarantee the safety and quality of foundation pit construction.

[0004] For example, the Chinese invention patent (application number: 202411234734.6) discloses a "removable air film canopy for winter foundation pit construction insulation and its assembly method". Its specification discloses: In order to solve the above problems, the current winter construction of the power transmission line tower foundation mostly uses plastic film to cover the foundation pit, burn charcoal at the bottom of the pit and use hot air energy pumps for circulation heating to ensure that the construction surface temperature reaches the temperature allowed by the regulations to prevent concrete frost heave disease. It can be seen that the above insulation measures have the following problems: 1. The heating energy consumption is extremely high, and charcoal burning maintenance can easily cause carbon monoxide poisoning to construction workers, making it difficult to ensure the life safety of operators; 2. In windy and snowy days, the insulation plastic film is often collapsed by the accumulated snow, resulting in construction cessation and delays in the construction period; 3. The insulation effect is poor, resulting in the occurrence of concrete frost heave disease; the above patents can prove the defects of the existing technology.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In the scheme of this application:

[0021] 1. In order to solve the problem that in the prior art, due to the large size of the membrane body, an arched structure is usually used for laying to ensure that it can resist the accumulation of snow. Although this method is effective, it greatly increases the complexity of construction, making the film coating process particularly cumbersome and inconvenient for efficient operation. In addition, the single-layer membrane body has poor performance in terms of heat insulation, especially in extreme climatic conditions, and its protective performance is greatly reduced. The present application uses air to inflate the double-layer membrane, so that the double-layer membrane wrapped around the outer wall of the storage roller continues to expand, and the elastic telescopic rod connected to the auxiliary plate is pushed to move in the limiting arc groove of the arc groove tube, so as to perform the film coating operation, so that the double-layer protective membrane structure can be inflated to achieve double-layer heat insulation while also realizing the rapid construction of the foundation pit protection structure, thereby improving its film coating efficiency;

[0022] 2. The two auxiliary plates are driven by the U-shaped groove to flip with the shaft tube and the central axis, so that the two sets of auxiliary plates are engaged with each other, and with the cooperation of the tooth plate, they can be tightly engaged, so that the two sets of relatively distributed film structures can be flipped and engaged under the push of the air to make them spliced, thereby improving the convenience of film assembly;

[0023] 3. During the movement of the auxiliary plate, the convex plate connected to the elastic telescopic rod squeezes and moves the pipe, and during the contact with the rib plate, the elastic telescopic rod is stretched and separated from the pipe, and air is re-introduced into the pipe. After passing through multiple rib plates, it can be squeezed and moved alternately to introduce air into the double-layer membrane, so that the membrane can be replenished with air in a peristaltic squeezing manner during the process of air reduction or air replenishment in the membrane, so as to ensure that the membrane remains full and improve its thermal insulation effect;

[0024] 4. During the film covering process, the auxiliary plate is driven by the continuously inflated double-layer film, and the elastic telescopic rod is pushed to move along the limit arc groove, which serves as a guide structure. During the assembly process, the two elastic telescopic rods move into the U-shaped groove, and the auxiliary plate connected by the two elastic telescopic rods is flipped with the central axis, and the tooth plate and the other group of auxiliary plates are engaged with each other, which serves as a splicing structure. During the supplementation process, the elastic telescopic rod drives the convex plate to move among the multiple ribs on the inner wall of the arc groove pipe, so that the convex plate alternately peristaltically extrude the pipeline, which serves as an extrusion structure, so that it can flexibly switch between the guide structure, the splicing structure and the extrusion structure, thereby improving its efficiency in protecting the foundation pit film covering;

[0025] 5. By releasing the double-layer film, the receiving roller drives the auxiliary shaft to rotate, and drives the arc-shaped plate connected to the disc to rotate in the convex wall tube, constantly changing its spatial volume, and sucking air into the guide airbag, and pushing the arc-shaped support plate upward to fit with the receiving roller, thereby ensuring the sealing of the bottom of the film coating process, and preventing the roller from releasing the film excessively, reducing the tension of the film;

[0026] 6. The airbag is continuously inflated, pushing the auxiliary tube downward, cooperating with the internal thread ring and rotating downward. After the auxiliary tube stops rotating, the positioning rod is pushed to shrink the positioning telescopic rod, and the angle between the first connecting rod and the second connecting rod is reduced, and the limiting rod is pushed out of the side window, so that it can be drilled and locked in the soil and then protruded and expanded, thereby realizing two-stage positioning and ensuring the stability of the film-covered structure after being fixed;

[0027] 7. During the limit support process, the disc drives the arc-shaped shifting plate to rotate in the convex wall tube, inflates the airbag, and makes the arc-shaped support plate move upward and contact the storage roller, which serves as a filling limit structure. During the positioning process, the airbag is continuously filled, and the lower bottom plate is pushed downward, so that the positioning rod pushes the auxiliary tube to move downward synchronously, which serves as a positioning structure, so that it can flexibly switch between the filling limit structure and the positioning structure, thereby improving the convenience of installation of the foundation pit protection membrane.

A double-layer membrane 208 is fixedly connected between two adjacent auxiliary plates 206. An air inlet pipe 207 is provided on the upper surface of the double-layer membrane 208 near one end of the auxiliary plate 206. A limiting auxiliary component 3 is provided on the outer wall of the auxiliary plate 206, which is connected to the air pump through the air inlet pipe 207. Air continuously enters the double-layer membrane 208, pushing the elastic telescopic rod 205 connected at both ends of the auxiliary plate 206 to move along the arc-shaped groove tube 201. With the continuous movement of the auxiliary plate 206, the storage roller 204 is pulled to release the double-layer membrane 208, thereby protecting the top of the foundation pit.

[0048] The intelligent environmental protection protection device suitable for foundation pit construction provided by the present invention uses air to inflate the double-layer membrane 208, so that the double-layer membrane 208 wrapped around the outer wall of the storage roller 204 continues to expand, and the elastic telescopic rod 205 connected to the auxiliary plate 206 is pushed to move in the limiting arc groove 202 of the arc groove tube 201, so as to perform the coating operation, so that the double-layer protective film structure can be inflated to achieve double-layer heat insulation and heat preservation, and at the same time, the foundation pit protection structure can be quickly constructed, thereby improving its coating efficiency.

[0049] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0051] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0052] Example 1, please refer to Figure 1 , Figure 4 and Figure 6, an intelligent environmental protection device suitable for foundation pit construction, wherein the position limiting auxiliary component 3 includes shaft cylinders 305 fixedly installed at opposite ends of two auxiliary plates 206, and the two shaft cylinders 305 are staggered, and a central axis 306 is movably connected between the two shaft cylinders 305, and one end of two adjacent elastic telescopic rods 205 away from the auxiliary plate 206 passes through the corresponding position limiting arc groove 202 and is fixedly connected with a convex plate 301, and the inner wall of the arc groove tube 201 is evenly distributed near the double-layer membrane 208 and fixedly connected with a plurality of ribs 302, and distributed between the two position limiting arc grooves 202, and the convex plate 301 is movably connected with the ribs 302, and the plurality of ribs 302 are fixedly connected with the inner wall of the arc groove tube 201. A first pipe 303 is provided on one side of each rib plate 302, and a second pipe 304 is provided on the other side of several rib plates 302. Tooth plates 308 are provided on both sides of the auxiliary plate 206. The auxiliary plate 206 is continuously driven by the expanded double-layer membrane 208 to move toward the U-shaped groove 203, and the elastic telescopic rods 205 at both ends of the auxiliary plate 206 are driven into the U-shaped groove 203. Due to the structure of the U-shaped groove 203, the two auxiliary plates 206 are flipped along the shaft tube 305 and the central axis 306. The four auxiliary plates 206 between the two groups of arc-shaped groove tubes 201 are engaged with each other with the cooperation of the tooth plates 308 on the surface to achieve mutual splicing.

[0053] The two auxiliary plates 206 are driven by the U-shaped groove 203 to flip over the shaft tube 305 and the central axis 306, so that the two groups of auxiliary plates 206 are engaged with each other, and with the cooperation of the tooth plate 308, they can be tightly engaged, so that the two groups of relatively distributed coating structures can be flipped and engaged under the push of air to be spliced, thereby improving the convenience of coating assembly.

[0054] Further, such as Figure 4 and Figure 6 As shown, the first pipe 303 passes through the arc groove tube 201 at one end near the support frame and is fixedly installed on the side wall of the double-layer membrane 208, and the second pipe 304 passes through the arc groove tube 201 at one end near the U-shaped groove 203 and is fixedly installed on the side wall of the double-layer membrane 208. The first pipe 303 and the second pipe 304 are relatively distributed in the arc groove tube 201, and the first pipe 303 and the second pipe 304 are fixedly connected to the outer wall of one side of the double-layer membrane 208 close to the double-layer membrane 208 with a check valve 307. While the air pump guides the air through the two sets of pipes, air can also be supplemented by peristaltic extrusion to increase the inflation speed of the double-layer membrane 208, and the check valve 307 is used for the conduit 502 to introduce air into the double-layer membrane 208 to prevent the air from being discharged from the double-layer membrane 208.

[0055] Further, such as Figure 3 and Figure 6As shown, a receiving roller 204 is provided at one end of the double-layer film 208 away from the auxiliary plate 206, an auxiliary shaft 507 is provided in the middle of the receiving roller 204, and is movably installed between the support frame plates 1, and a support assembly 5 is provided on one side of the receiving roller 204, and the receiving roller 204 is supported by the auxiliary shaft 507 to facilitate the release and storage of the double-layer film 208.

[0056] Embodiment 2 further optimizes the intelligent environmental protection device suitable for foundation pit construction provided in Embodiment 1. Specifically, Figure 3 , Figure 5 and Figure 7 As shown, the support assembly 5 includes a convex wall cylinder 501 movably mounted on one side of the storage roller 204, one end of the auxiliary shaft 507 penetrates the convex wall cylinder 501 and is fixedly connected to a disc 503, the outer wall of the disc 503 is symmetrically and evenly distributed and fixedly connected to an arc-shaped dial plate 504, and the end away from the disc 503 is in contact with the inner wall of the convex wall cylinder 501, the lower end of the convex wall cylinder 501 is fixedly connected to a guide tube 502, and the other end of the guide tube 502 is fixedly connected to an air bag 505, the convex wall cylinder 501 is provided with an air guide hole 508 at one end close to the arc-shaped groove tube 201, and the air guide hole 508 penetrates the arc-shaped groove tube 201, a lower bottom plate 506 is provided below the air bag 505, and a positioning assembly 6 is provided below the lower bottom plate 506, and the storage roller 204 is continuously releasing the double-layer film 2 08 rotates during the process, and after the rotation, the auxiliary shaft 507 is driven to rotate accordingly, so that the disk 503 in the convex wall tube 501 rotates, and the arc-shaped paddle 504 on the outer wall of the disk 503 continuously contacts the inner wall of the convex wall tube 501. Since one end of the convex wall tube 501 is convex, it rotates continuously. Since the arc-shaped paddle 504 has a certain elasticity, the volume of its space is continuously changed, and the pumped air is introduced into the air guide hole 508, and then introduced into the air bag 505 through the conduit 502, which will push the arc-shaped support plate 509 to move upward and fit with the storage roller 204, preventing air from entering the double-layer film 208 wrapped in the storage roller 204, thereby reducing the air in the double-layer film 208 laid in the coating.

[0057] By releasing the double-layer film 208, the storage roller 204 drives the auxiliary shaft 507 to rotate, and drives the arc-shaped plate 504 connected to the disc 503 to rotate in the convex wall tube 501, constantly changing its spatial volume, and drawing air into the guide airbag 505, and pushing the arc-shaped support plate 509 upward to fit with the storage roller 204, thereby ensuring the sealing of the bottom of the coating process, preventing the roller from releasing the film excessively, and reducing the tension of the film.

[0058] Further, such as Figure 7As shown, an arc-shaped support plate 509 is fixedly connected above the airbag 505, and the upper part of the arc-shaped support plate 509 is movably connected to the lower part of the storage roller 204. The arc-shaped support plate 509 contacts the storage roller 204 to ensure the tension of the double-layer film 208 during the coating process.

[0059] Embodiment 3 further optimizes the intelligent environmental protection device for foundation pit construction provided in Embodiment 1 or 2. Specifically, Figure 7 , Figure 8 and Fig. 9 As shown, the positioning assembly 6 includes a plurality of positioning rods 601 evenly distributed in a straight line and fixedly installed below the lower base plate 506, a positioning telescopic rod 605 is movably connected below the positioning rod 601, a conical rod 604 is fixedly connected to the other end of the positioning telescopic rod 605, an auxiliary cylinder 602 is fixedly connected above the conical rod 604, an inner thread ring 614 is movably connected to the outer wall of the auxiliary cylinder 602, and the outer wall of the inner thread ring 614 is fixedly installed below the support frame plate 1, and two arc frames 4 are symmetrically evenly distributed and fixedly connected below the support frame plate 1, and the airbag 505 thereof is continuously inflated, and the airbag 505 is inflated. The lower bottom plate 506 below 05 pushes the positioning rod 601 to move downward. Since the auxiliary tube 602 on which the positioning rod 601 is sleeved is threadedly connected with the internal thread ring 614, as the positioning rod 601 pushes, the auxiliary tube 602 rotates downward, driving the conical rod 604 to move downward and enter the soil. When it cannot move downward, its positioning telescopic rod 605 contracts, and with the cooperation of the first connecting rod 608 and the second connecting rod 612, the angle between them gradually decreases, and the limiting rod 610 is led out with the side window 603 to be in close contact with the soil, thereby achieving positioning.

[0060] The airbag 505 is continuously expanded, pushing the auxiliary tube 602 downward, cooperating with the internal threaded ring 614 and rotating downward. After the auxiliary tube 602 stops rotating, the positioning rod 601 pushes the positioning telescopic rod 605 to shrink, and the angle between the first connecting rod 608 and the second connecting rod 612 is reduced, and the limit rod 610 is pushed out from the side window 603, so that it can drill in the soil, lock and then protrude and expand, thereby realizing two-stage positioning and ensuring the stability of the film structure after fixation.

[0061] Further, such as Figure 8 and Fig. 9As shown, the outer wall of the positioning telescopic rod 605 is fixedly connected with a fixed ring plate 606, and a plurality of first rotating frames 607 are evenly distributed in a circle below the fixed ring plate 606, and the other end of the first rotating frame 607 is movably connected with a first connecting rod 608, and a plurality of fourth rotating frames 613 are evenly distributed in a circle on the upper surface of the conical rod 604, and the other end of the fourth rotating frame 613 is movably connected with a second connecting rod 612, and the first rotating frame 607, the second rotating frame 609, the third rotating frame 611 and the fourth rotating frame 613 are used as hinge structures to cooperate with the change of the angle between the first connecting rod 608 and the second connecting rod 612, and the limiting rod 610 is pushed to achieve protruding expansion and increase lateral contact with the soil.

[0062] Further, such as Figure 8 and Fig. 9 As shown, the other end of the first connecting rod 608 is movably connected to the second rotating frame 609, and the other end of the second connecting rod 612 is movably connected to the third rotating frame 611. The other ends of the second rotating frame 609 and the third rotating frame 611 are provided with a limiting rod 610. The outer wall of the auxiliary cylinder 602 is provided with a plurality of side windows 603 evenly distributed in a circle. The side windows 603 are movably connected to the limiting rod 610. The side windows 603 are used to limit the way in which the limiting rod 610 is guided out to prevent the limiting rod 610 from being deflected during the displacement process.

[0063] The use process of the intelligent environmental protection protection device suitable for foundation pit construction provided by the present invention is as follows:

[0064] Working principle: The staff places two relatively distributed film covering mechanisms on both ends of the foundation pit, and places the arc frame 4 at the corresponding position. The air pump is connected to the air inlet pipe 207 by a pipeline, and the pump body is started, and air enters the double-layer membrane 208:

[0065] Laminating: Air continuously enters the double-layer membrane 208, pushing the elastic telescopic rods 205 connected to both ends of the auxiliary plate 206 to move along the limiting arc groove 202. As the auxiliary plate 206 continues to move, the double-layer membrane 208 is pulled, and as the storage roller 204 rotates with the auxiliary shaft 507, the double-layer membrane 208 is released, so that the double-layer membrane 208 is released during the process of inflating the double-layer membrane 208, thereby protecting the top of the foundation pit;

[0066] Splicing: The auxiliary plates 206 are continuously driven by the expanded double-layer membrane 208 to move toward the U-shaped groove 203, and the elastic telescopic rods 205 at both ends of the auxiliary plates 206 are driven into the U-shaped groove 203. Due to the structure of the U-shaped groove 203, the two auxiliary plates 206 are turned along the shaft tube 305 and the central axis 306. The four auxiliary plates 206 between the two groups of arc-shaped groove tubes 201 bite each other with the cooperation of the tooth plates 308 on the surface to achieve mutual splicing;

[0067] Lamination limit: the storage roller 204 rotates in the process of continuously releasing the double-layer film 208, and after the rotation, the auxiliary shaft 507 is driven to rotate accordingly, so that the disc 503 in the convex wall tube 501 rotates, and the arc-shaped paddle 504 on the outer wall of the disc 503 continuously contacts the inner wall of the convex wall tube 501. Since one end of the convex wall tube 501 is convex, it rotates continuously. Since the arc-shaped paddle 504 has a certain elasticity, the volume of its space is continuously changed, and the pumped air is introduced into the air guide hole 508, and then introduced into the air bag 505 through the conduit 502, and the arc-shaped support plate 509 is pushed upward to fit with the storage roller 204, preventing air from entering the double-layer film 208 wrapped in the storage roller 204, and reducing the air in the double-layer film 208 laid in the lamination;

[0068] Positioning: The airbag 505 is continuously inflated, and the lower bottom plate 506 below the airbag 505 pushes the positioning rod 601 to move downward. Since the auxiliary cylinder 602 sleeved by the positioning rod 601 is threadedly connected with the internal thread ring 614, as the positioning rod 601 pushes, the auxiliary cylinder 602 rotates downward, driving the conical rod 604 to move downward and enter the soil. When it cannot move downward, the positioning telescopic rod 605 contracts, and with the cooperation of the first connecting rod 608 and the second connecting rod 612, the angle between them gradually decreases, and the limiting rod 610 is led out from the side window 603 to be in close contact with the soil, thereby achieving positioning;

[0069] Supplement: Since the double-layer membrane 208 is large in size, there will be a certain amount of air leakage inside it. At this time, the double-layer membrane 208 will shrink and drive the auxiliary plate 206 away from the U-shaped groove 203. After moving away, it drives the convex plate 301 to follow the movement. Under the elastic support of the elastic telescopic rod 205, the first pipe 303 is squeezed, and when it moves to the rib 302, it is separated from the squeezing of the first pipe 303, and the air enters the pipe. After separating from the rib 302, it continues to move and squeeze the first pipe 303, so that the air inside the pipe is squeezed into the double-layer membrane 208. The air in the double-layer membrane 208 is replenished, and the auxiliary plate 206 is pushed in the opposite direction, so that the air in the second pipe 304 is alternately squeezed and introduced into the double-layer membrane 208, so that the elastic telescopic rod 205 can squeeze the pipe during the round trip and introduce air into the double-layer membrane 208 for replenishment.
