Description

Technical Field

[0001] The invention relates to the technical field of pipelines, and in particular to a pipe-blocking protective member used for sealing a gap between a basement side wall and a pipeline. Background Art

[0002] In the construction of the basement, in order to ensure the smooth drainage of the entire building, a pipe is often installed horizontally through the side wall of the basement. However, due to the construction errors during the installation of the pipe, there will be a certain gap between the pipe and the side wall after installation, which will cause external moisture and humid air to enter the basement through the gap, causing damage to the basement structure, such as steel corrosion or concrete deterioration, etc., which will have an adverse effect on the structural safety of the basement. The existing technology usually uses manual filling of flexible materials or grouting to seal the gap between the side wall and the pipe. Although it solves the gap problem between the side wall and the pipe to a certain extent, it still has defects. For example, when manually filling flexible materials or grouting, the construction process is complicated, and the material durability is insufficient during sealing. After long-term use, the filling or grouting materials will gradually age and crack, which cannot meet the long-term sealing effect, thereby greatly affecting the overall anti-leakage effect of the basement. Summary of the invention

[0003] The object of the present invention is to provide a sealing pipe protective fitting for sealing the gap between the side wall of the basement and the pipeline, which can at least partially overcome the above-mentioned technical problems, enable it to effectively seal the gap between the side wall of the basement and the pipeline for a long time, make it convenient and quick to operate during sealing, and to a certain extent can meet the sealing of gaps of different sizes, making its sealing effect more excellent.

[0004] The present invention is achieved through the following technical solutions:

[0005] A plugging and protecting pipe member for sealing the gap between a basement side wall and a pipe, comprising a pipe penetrating the side wall, a plugging pipe being arranged outside the pipe body of the pipe penetrating the side wall, the plugging pipe being attached to the outside of the pipe and being adapted to a through hole preset on the side wall for passing the pipe, and being used to plug the gap between the pipe and the through hole;

[0006] The plugging tube includes a plugging portion and an adjusting portion, wherein the adjusting portion is used to push the plugging portion to deform and expand so as to adapt and fit with the through hole, and the plugging portion includes an extension piece and an expansion mechanism, wherein the extension piece is connected to the pipe body position where the pipe passes through the through hole on the side wall through the expansion mechanism, and is arranged around the outer circumference of the pipe;

[0007] The adjustment portion includes two groups of opposing adjustment mechanisms, which are respectively located at the two ends of the pipeline and connected to the two sides of the expansion mechanism. The expansion mechanism is pushed and adjusted in opposite directions by the two groups of opposing adjustment mechanisms, so that the expansion mechanism drives the extension piece to bulge toward the outer side surface of the through hole to block and close the gap between the pipeline and the through hole.

[0008] It should be noted that in the basement anti-leakage project, the existence of gaps between the side wall and the pipe is inevitable. It is often caused by some error parameters in the construction process, which leads to deviations between the side wall through-hole and the outer diameter of the pipe, which in turn causes the side wall through-hole to be too large. As a result, the pipe and the gap are not completely fitted together, resulting in the appearance of gaps. The appearance of gaps often causes great harm to the basement, and it is very easy for outside rainwater or humid gas to enter, causing erosion of the underground steel structure and concrete structure, which in turn causes damage to the basement structure and affects the service life of the building.

[0009] Therefore, in order to avoid this problem, the present technical scheme hereby proposes a sealing pipe protective fitting for sealing the gap between the basement side wall and the pipeline. The difference between the prior art is that a sealing pipe is arranged on the outside of the pipeline passing through the through hole of the basement side wall, and the sealing pipe includes a sealing part and an adjusting part. When there is a gap between the pipeline and the through hole of the side wall, the sealing part can be pushed to deform and expand by the adjusting part so as to abut against the through hole of the side wall, thereby filling the gap space between the pipeline and the through hole of the side wall to achieve effective sealing. Furthermore, the present technical scheme can adapt and adjust according to the size of the gap when the sealing part is pushed to deform and expand by the adjusting part so as to better fit the through hole of the side wall, thereby achieving effective sealing of gaps of different sizes, thereby making it more suitable for sealing.

[0010] In some preferred technical solutions, any group of the opposing adjustment mechanisms includes a thread groove, a threaded sleeve and a rotating sleeve, the thread groove is provided on the outer peripheral surface of one end of the pipe, the threaded sleeve is provided corresponding to the thread groove, and is threadedly meshed with the thread groove through the threads on its inner wall, the rotating sleeve is provided on the outer peripheral surface of the threaded sleeve and is rotationally connected to the threaded sleeve, and the expansion mechanism is located on the side of the rotating sleeve and is connected to it. The above technical solution further illustrates the specific structure of the opposing adjustment structure, and based on the clear action principle of the opposing adjustment structure, the operator can drive the rotating sleeve to move axially on the outside of the pipe through the thread groove by rotating the threaded sleeve, and then promote the expansion mechanism to drive the extension piece to arch and deform upward and abut against the through hole after the axial movement, so as to effectively block the gap between the pipe and the through hole on the side wall.

[0011] Furthermore, the tops of the two rotating sleeves are connected to the two side edges of the extension sheet respectively, so that the rotating sleeves can press the two side edges of the extension sheet after moving toward each other, causing it to bend upward and deform.

[0012] It should be noted that in the present technical solution, the expansion mechanism has at least two different structures, one of which is as follows: the expansion mechanism includes a first connecting rod arranged in a circumferential array on the outer periphery of the pipe, any of the first connecting rods includes two mutually hinged first struts, the hinges of the two first struts abut against the inner side of the extension piece facing the pipe, and are used to provide upward pressure support to the extension piece when it bulges out toward the outer side of the through hole. Based on the expansion mechanism described above, when the operator rotates the threaded sleeve to drive the rotating sleeve to move toward each other at both ends of the pipe through the threaded groove, the rotating sleeve is convenient for squeezing the first strut corresponding to it, thereby causing the first strut to deflect, so that the bottom ends thereof approach each other, and driving the top end to lift the middle part of the extension piece upward, thereby causing the extension piece to arch upward and deform and abut against the through hole, so as to facilitate the anti-seepage plugging of the gap between the pipe and the through hole of the side wall.

[0013] Based on the above technical solution, the ends of the two first support rods that are away from each other are respectively hinged to their corresponding rotating sleeves, so that when the rotating sleeves move toward each other under the drive of the threaded rotating sleeves, they can push the first support rods to deflect, thereby causing the top ends of the first support rods to push upward to press the extension sheet upwards.

[0014] In the present technical solution, another specific structure of the expansion mechanism is: the expansion mechanism includes a connecting sleeve that is clamped in the middle of the pipeline and located in the middle position of the two opposing adjustment mechanisms, and expansion rods are arranged in a circular array on the outer circumference of the connecting sleeve. Each group of expansion rods includes two second struts, the bottom ends of the two second struts are close to each other and hinged on the connecting sleeve, and the top ends of the two second struts are far away from each other and connected to the two sides of the extension piece. There are oblique struts hinged between the two second struts and the corresponding opposing adjustment mechanisms, which are connected at the edge positions on both sides of the extension piece and connected to the corresponding rotating sleeves to form a sealing rubber sleeve for shielding and sealing the expansion rods. Based on the expansion mechanism recorded above, when the operator rotates the threaded sleeve to drive the rotating sleeve to move axially toward each other at both ends of the pipe through the threaded groove, the rotating sleeve can push the second connecting rod to deflect through the diagonal support rod, and then after the second connecting rod is deflected, its top end moves in a direction approaching each other to cause the extension piece to bend and deform and arch upward. At the same time, multiple groups of expansion rods are sealed and shielded by sealing rubber sleeves, so that they can cooperate with the bent and upwardly arched extension pieces to completely block the gap between the pipe and the side wall through hole.

[0015] In the above solution, further, both ends of any of the diagonal bracing rods are respectively hinged to the second bracing rod and the rotating sleeve, so that the rotating sleeve can push the diagonal bracing rod to deflect after axial movement.

[0016] Based on the above technical solution, it is necessary to add that an inflatable airbag is also bonded at the middle position of the inner surface of the extension piece, and the inflatable airbag is connected to the inflatable component inserted on the ferrule, and the inflatable component is in a ring array and is arranged around the connecting ferrule. When the second connecting rod deflects and approaches each other to cause the extension piece to deform, the middle part of the extension piece does not have sufficient support, so it may be deformed downward. In order to avoid this problem, the extension piece cannot block the gap between the pipeline and the side wall through hole. In this application, an inflatable airbag is provided at the middle position of the inner surface of the extension piece, and it is connected to the inflatable component, so that when the second support rod pushes the extension piece to deform and bend, the inflatable component can inflate the inflatable airbag in time to make the inflatable airbag start to expand. After the inflatable airbag expands, it can provide an upward supporting force to the extension piece to promote the extension piece to bend upward under the upward supporting force provided by the inflatable airbag after being squeezed and deformed, and abut against the inner wall of the side wall through hole.

[0017] In the above technical solution, in order to facilitate the inflation component to inflate the expansion airbag at the same time when the extension piece is arched and deformed, the technical solution hereby specifically describes the specific structure of the inflation component. Any of the inflation components includes an air cylinder, a piston and a push rod. The air cylinder is arranged along the axial direction of the pipeline. The piston is symmetrically arranged at both ends of the air cylinder and is slidably adapted to the air cylinder. The push rod is arranged corresponding to the piston and is located at both ends of the air cylinder. One end of any of the push rods is connected to the rotating sleeve, and the other end extends into the air cylinder and is connected to the piston. The push rod is driven to move by the rotating sleeve, so that the push rod pushes the piston to move in the air cylinder and pushes the gas in the air cylinder into the expansion airbag to expand the expansion airbag. Based on the above structure, when the extension piece is squeezed and deformed by the second support rod, the inflation component can synchronously inflate the expansion airbag with the deformation process of the extension piece, so that the expansion airbag can timely and effectively support the extension piece upward.

[0018] In the above technical solution, the gas storage cylinder is filled with gas and is connected to the expansion airbag through a hose.

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

[0020] 1. The present invention arranges a plugging pipe outside the pipe passing through the through hole of the side wall of the basement, and the plugging pipe includes a plugging part and an adjusting part. When there is a gap between the pipe and the through hole of the side wall, the plugging part can be pushed by the adjusting part to deform and expand so as to abut against the through hole of the side wall, thereby filling the gap space between the pipe and the through hole of the side wall to achieve effective leak-proof plugging. Furthermore, when the plugging part is pushed by the adjusting part to deform and expand, it can be adjusted according to the size of the gap to better fit the through hole of the side wall, thereby achieving effective plugging of gaps of different sizes, thereby making it more suitable for plugging;

[0021] 2. The present invention further provides an inflatable airbag at the middle position of the inner surface of the extension piece, and connects it with the inflation assembly, so that when the second support rod pushes the extension piece to deform and bend, the inflation assembly can inflate the inflatable airbag in time to make the inflatable airbag begin to expand. After the inflatable airbag is inflated, it can provide an upward supporting force to the extension piece to promote the extension piece to bend upward under the upward supporting force provided by the inflatable airbag after being squeezed and deformed, and abut against the side wall through hole, so that after it cooperates with the sealing rubber sleeve, the gap between the pipeline and the side wall through hole is sealed for seepage prevention. At the same time, after the inflatable airbag is inflated, the extension piece can be further inflated and squeezed, so that the extension piece can fully adapt to the shape of the side wall through hole, so that the extension piece can fit it more closely, and thus the leak-proof sealing effect is better.

[0033] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and drawings. The schematic implementation modes and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention. It should be noted that the present invention is already in the actual development and use stage.

[0034] Embodiment 1:

[0035] Please refer to the attached Figures 1 to 3 A plugging and protecting pipe member for sealing the gap between the side wall and the pipe of a basement, comprising a pipe 1 penetrating the side wall, a plugging pipe 2 is arranged outside the pipe body of the pipe 1 penetrating the side wall, the plugging pipe 2 is attached to the outside of the pipe 1 and is adapted to a through hole preset on the side wall for passing the pipe 1, and is used to plug the gap between the pipe 1 and the through hole;

[0036] The plugging tube 2 includes a plugging portion and an adjusting portion, wherein the adjusting portion is used to push the plugging portion to deform and expand so as to adapt and fit with the through hole, and the plugging portion includes an extension piece 20 and an expansion mechanism, wherein the extension piece 20 is connected to the pipe body position of the through hole on the side wall of the pipe 1 through the expansion mechanism, and is arranged around the outer circumference of the pipe 1;

[0037] The adjustment portion includes two groups of opposing adjustment mechanisms 230, which are respectively located at the two ends of the pipe 1 and connected to the two sides of the expansion mechanism. The expansion mechanism is pushed and adjusted in opposite directions by the two groups of opposing adjustment mechanisms 230, so that the expansion mechanism drives the extension piece 20 to bulge toward the outer side surface of the through hole to block and close the gap between the pipe 1 and the through hole.

[0038] The present embodiment proposes a pipe sealing protective fitting for sealing the gap between the basement side wall and the pipeline. The pipe 2 is provided with a sealing pipe 2 outside the pipeline 1 passing through the through hole of the basement side wall, and the sealing pipe 2 includes a sealing part and an adjusting part. When there is a gap between the pipeline 1 and the through hole of the side wall, the sealing part can be pushed by the adjusting part to deform and expand so as to abut against the through hole of the side wall, thereby filling the gap space between the pipeline 1 and the through hole of the side wall to achieve effective sealing. Furthermore, when the sealing part is pushed to deform and expand by the adjusting part, it can be adjusted according to the size of the gap to better fit the through hole of the side wall, thereby achieving effective sealing of gaps of different sizes, thereby making it more suitable for sealing.

[0039] Preferably, in order to facilitate the opposite adjustment mechanism 230 to push the blocking portion to deform and expand, so that the extension piece 20 is bent and deformed to block the gap between the pipeline 1 and the side wall through hole, the specific structure of the opposite adjustment mechanism 230 is described here. Figure 1 and Figure 4 As shown in the figure, any group of the opposing adjustment mechanism 230 includes a thread groove 2300, a threaded sleeve 2301 and a rotating sleeve 2302. The thread groove 2300 is provided on the outer peripheral surface of one end of the pipe 1. The threaded sleeve 2301 is arranged corresponding to the thread groove 2300 and is threadedly engaged with the thread groove 2300 through the threads on its inner wall. The rotating sleeve 2302 is sleeved on the outer peripheral surface of the threaded sleeve 2301 and is rotatably connected to the threaded sleeve 2301. The expansion mechanism is located on the side of the rotating sleeve 2302 and is connected to it. The above technical scheme further illustrates the specific structure of the opposing adjustment structure, and based on it, the action principle of the opposing adjustment structure can be clearly understood, specifically: the operator rotates the threaded rotary sleeve 2301 to drive the rotating sleeve 2302 to move axially on the outside of the pipe 1 through the threaded groove 2300 after it rotates, thereby causing it to move axially and then push the expansion mechanism to drive the extension sheet 20 to arch and deform upward and abut against the through hole, so as to effectively seal the gap between the pipe 1 and the through hole of the side wall.

[0040] In order to facilitate the movement of the rotating sleeve 2302, the extension sheet 20 can be pushed to deform, bend and arch upward, a preferred implementation method thereof is described here, please refer to Figure 3The tops of the two rotating sleeves 2302 are respectively connected to the two side edges of the extension sheet 20. It is convenient for the rotating sleeves 2302 to squeeze the two side edges of the extension sheet 20 after moving toward each other, so as to cause it to arch and deform upward.

[0041] Based on the above embodiment, it should be noted that in the technical solution, the expansion mechanism has at least two different structures in order to achieve the expansion and bending of the extension sheet 20. This embodiment describes one of the specific structures. Figure 1 As shown, the expansion mechanism includes a circumferential array of first connecting rods on the periphery of the pipe 1, and any of the first connecting rods includes two first support rods 2101 hinged to each other, and the hinges of the two first support rods 2101 are in contact with the inner side surface of the extension piece 20 facing the pipe 1, so as to provide upward pressure support to the extension piece 20 when the outer side surface of the extension piece 20 protrudes and arches toward the through hole.

[0042] Based on the above-mentioned expansion mechanism, during the specific implementation, the operator rotates the threaded sleeve 2301 so that the threaded sleeve 2301 rotates and drives the rotating sleeve 2302 to move toward each other at both ends of the pipeline 1 through the threaded groove 2300, and then the rotating sleeve 2302 moves to squeeze and push the bottom end of the first support rod 2101 to cause the first support rod 2101 to deflect, so that the bottom ends of the first support rod 2101 are close to each other, and drive the top end to lift the middle part of the extension piece 20 upward, thereby causing the extension piece 20 to arch upward and deform and abut against the through hole, so as to facilitate the anti-seepage sealing of the gap between the pipeline 1 and the through hole of the side wall.

[0043] Based on the above embodiment, it is further explained that the ends of the two first support rods 2101 that are away from each other are respectively hinged to their corresponding rotating sleeves 2302. When the rotating sleeves 2302 are driven by the threaded rotating sleeves 2301 to move toward each other, they can push the first support rods 2101 to deflect, thereby causing the top of the first support rods 2101 to push upward to press the extension sheet 20 upward. Figure 2 It has been shown in .

[0044] Embodiment 2:

[0045] Please refer to Figures 4 to 7Based on the above embodiment, another preferred embodiment of the expansion mechanism is further described here, the expansion mechanism includes a connecting sleeve 2200 that is clamped in the middle of the pipeline 1 and located in the middle position of the two opposing adjustment mechanisms 230, and a plurality of groups of expansion rods in a circular array on the outer circumference of the connecting sleeve 2200, each group of expansion rods includes two second support rods 2201, the bottom ends of the two second support rods 2201 are close to each other and hinged on the connecting sleeve 2200, and the top ends of the two second support rods 2201 are away from each other and connected to the two sides of the extension piece 20, and the oblique support rods 2202 are hinged between the two second support rods 2201 and the corresponding opposing adjustment mechanisms 230, and the sealing rubber sleeves 2203 are connected at the edge positions on both sides of the extension piece 20 and connected to the corresponding rotating sleeves 2302 for shielding and sealing the expansion rods.

[0046] Based on another specific structure of the expansion mechanism recorded above, during the specific implementation, the operator can also rotate the threaded sleeve 2301 so that the threaded sleeve can move axially at both ends of the pipe 1 through the thread groove 2300 after rotation, and when the threaded sleeve 2301 moves, it can synchronously drive the rotating sleeve 2302 to move, so that after the rotating sleeve 2302 moves, it pushes the second connecting rod to deflect through the diagonal support rod 2202, so that after the second connecting rod is deflected, its top ends are close to each other, and the extension piece 20 is caused to arch and deform to abut against the inner wall of the side wall through hole, and after the multiple groups of expansion rods are sealed and blocked by the sealing rubber sleeve 2203, it can cooperate with the bent and upward arched extension piece 20 to completely block the gap between the pipe 1 and the side wall through hole.

[0047] Based on the expansion mechanism described in the above embodiment, it is further preferred that two ends of any diagonal support rod 2202 are respectively hinged to the second support rod 2201 and the rotating sleeve 2302, so that the rotating sleeve 2302 pushes the diagonal support rod 2202 to deflect after axial movement.

[0048] Based on the above-mentioned embodiments, it is necessary to further explain that, due to the use of the expansion mechanism described in this embodiment, when the extension piece 20 is squeezed and deformed, the bottom middle position of the extension piece 20 cannot be effectively supported, causing the extension piece 20 to be deformed downwardly concavely instead of arching upwardly when it is compressed and deformed, thereby making it difficult for the extension piece 20 to block the gap between the pipe 1 and the side wall through hole. In view of this, the present application also bonds an expansion airbag 30 at the middle position of the inner surface of the extension piece 20 (the expansion airbag 30 is annular as a whole and is arranged in a circle around the inner surface of the extension piece 20), and the expansion airbag 30 is connected to the inflation component 31 inserted on the connecting sleeve 2200, and the inflation component 31 is in an annular array and is arranged around the connecting sleeve 2200. Figure 4 and Figure 6 It is shown in the figure. By providing an inflatable airbag 30 at the middle position of the inner surface of the extension piece 20 and connecting it with the inflatable assembly 31, when the second support rod 2201 pushes the extension piece 20 to deform and bend, the inflatable assembly 31 can inflate the inflatable airbag 30 in time, so that the inflatable airbag 30 starts to expand. After the inflatable airbag 30 expands, it can provide an upward supporting force to the extension piece 20, so as to promote the extension piece 20 to continue to bend upward under the upward supporting force provided by the inflatable airbag 30 after being squeezed and deformed, and to abut against the through hole of the side wall. It should be emphasized here that, since the inner shape of the side wall through hole is not completely flat, its inner wall may be uneven, resulting in that the extension sheet 20 cannot completely fit the side wall through hole after being arched and deformed, resulting in a gap between the extension sheet 20 and the side wall through hole, thereby causing the sealing to be loose. Therefore, in this embodiment, the expansion airbag 30 is added, which not only simply supports the extension sheet 20, but also can further squeeze the extension sheet 20 after the expansion airbag 30 is inflated. As a preferred supplement, a rubber pad (not shown in the figure) can be arranged on the outside of the extension sheet 20 at the position corresponding to the expansion airbag 30, so that the extension sheet 20 can squeeze the rubber pad to produce a certain deformation after being squeezed, so as to fit more closely with the inner wall curved surface of the side wall through hole, thereby avoiding the formation of a gap between the extension sheet 20 and the through hole and causing a poor seal. At the same time, the contact part between the extension sheet 20 and the side wall through hole is protected by the rubber pad to avoid damage when it is squeezed with the side wall through hole, which affects the sealing effect.

[0049] In the above technical solution, in order to facilitate the inflation component 31 to inflate the expansion airbag 30 at the same time when the extension sheet 20 is arched and deformed, the technical solution hereby specifically describes the specific structure of the inflation component 31. For details, please refer to Figure 5Any of the inflation components 31 includes an air cylinder 310, a piston 311 and a push rod 312. The air cylinder 310 is arranged along the axial direction of the pipeline 1. The piston 311 is symmetrically arranged at both ends of the air cylinder 310 and is slidably adapted to the air cylinder 310. The push rod 312 is arranged corresponding to the piston 311 and is located at both ends of the air cylinder 310. One end of any of the push rods 312 is connected to the rotating sleeve 2302, and the other end extends into the air cylinder 310 and is connected to the piston 311. The push rod 312 is driven to move by the rotating sleeve 2302, so that the push rod 312 pushes the piston 311 to move in the air cylinder 310, and pushes the gas in the air cylinder 310 into the expansion airbag 30 to expand the expansion airbag 30. Based on the above structure, when the extension piece 20 is squeezed and deformed by the second support rod 2201, the inflation component 31 can inflate the expansion airbag 30 synchronously with the deformation process of the extension piece 20, so that the expansion airbag 30 can timely and effectively support the extension piece 20 upward.

[0050] In the above embodiment, it is further preferred that the gas cylinder 310 is filled with gas and is connected to the expansion airbag 30 through the hose 32, and any two adjacent gas cylinders 310 are connected through the reinforcing rib 4, such as Figure 8 As shown, by setting the reinforcing rib 4, the structural strength of the connecting sleeve 2200 can be further strengthened, so that it can further reinforce and protect the middle part of the pipeline 1 and avoid rupture and damage to the middle part of the pipeline 1.

[0051] It should be noted that in the above embodiment, the extension sheet 20 can be made of a material with certain strength and good ductility. For the present technical solution, it is preferably made of metal foil (such as copper foil or aluminum foil).
