Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and to a pipe connection device for lightweight wellpoint dewatering. Background Technology
[0002] In the field of building construction, dewatering is a common procedure during the foundation pit construction stage. The efficiency and effectiveness of dewatering directly determine the speed of construction progress during the soil protection and dewatering stage. Due to site constraints and construction procedures, not all projects can use the wellpoint method for dewatering. Therefore, the lightweight wellpoint dewatering method brings many conveniences to construction.
[0003] Lightweight wellpoints typically consist of a vacuum pump, a main pipeline, and branch pipelines for each wellpoint, forming a vacuum loop system. The vacuum pump continuously creates a vacuum, generating negative pressure within the pipes to draw groundwater to the surface, thus achieving a precipitation effect.
[0004] On-site pipe connections use elbows, tees, and other fittings, and are fixed by using a large-diameter pipe inside a small-diameter pipe. Sealing gaskets and plastic wrap are wrapped around the pipe openings multiple times to ensure the seal at the joints. However, as rainfall continues, the durability of this method is poor, and water inside the pipe will slowly seep out from the plastic wrapping at the joints, causing the pipe seal to deteriorate and reducing the efficiency of rainfall. Utility Model Content
[0005] To address the technical problems in the prior art, this utility model provides a pipe connection device for lightweight wellpoint dewatering, including two connecting seats, an adjustment mechanism, and an elastic rubber ring installed at the joint of two hoses. The two connecting seats are located on both sides of the elastic rubber ring and are fixedly connected to the two hoses respectively. The two connecting seats are connected by the adjustment mechanism, and the two hoses move closer to each other and fit tightly against the two ends of the elastic rubber ring under the action of the adjustment mechanism.
[0006] Furthermore, the adjustment mechanism includes a limiting plate, a screw, and an elastic component. The limiting plate is fixedly installed on one of the connecting seats, and a limiting groove is formed on the limiting plate. One end of the screw is rotatably connected to the other connecting seat, and the elastic component is sleeved on the other end of the screw. When the other end of the screw engages with the limiting groove around the rotation point, the elastic component is located on the side of the limiting plate away from the rotation point and abuts against the limiting plate.
[0007] Furthermore, the elastic component includes a connecting plate, a spring, a pressure plate, and a nut. The connecting plate, spring, and pressure plate are all slidably sleeved on the screw. The two ends of the spring are fixedly connected to the connecting plate and the pressure plate, respectively. The nut is threadedly connected to the screw and fits against the pressure plate. When the screw engages with the limiting groove, the connecting plate abuts against the limiting plate under the elastic force of the spring.
[0008] Furthermore, the inner diameter of the elastic rubber ring is not greater than the inner diameter of the hose, and the outer diameter of the elastic rubber ring is not less than the outer diameter of the hose.
[0009] Furthermore, both ends of the elastic rubber ring are provided with annular grooves, which cooperate with the hose.
[0010] Furthermore, a rubber pad is installed between the connector and the hose.
[0011] Furthermore, the end of the rubber pad that contacts the hose is provided with multiple elastic protrusions.
[0012] Beneficial effects:
[0013] 1. In this utility model, the two connecting seats, the adjusting mechanism and the elastic rubber ring are designed to tightly fit the ends of the two hoses with the elastic rubber ring, ensuring sealing performance and facilitating disassembly and assembly.
[0014] 2. In this utility model, the setting of the limiting plate, screw, elastic component, and limiting groove allows for convenient fixing or disassembly of the two connecting seats. Simultaneously, it enables the two hoses to fit tightly together under the action of elasticity. Specifically, when fixing the two connecting seats, simply rotate the screw to engage with the limiting groove on the limiting plate, and then attach the elastic component to the side of the limiting plate away from the other connecting seat. When disassembling the two connecting seats, simply use external force to separate the elastic component from the limiting plate, and then rotate the screw to disengage it from the limiting groove. The connecting plate and spring... The setting of the pressure plate and nut allows the spring force to make the connecting plate and the limiting plate fit or separate, thereby realizing the connection and disassembly of the two hoses. At the same time, the initial spring force can be freely adjusted to meet the adjustment of different forces between the two hoses. Specifically, when the nut moves towards the rotation point, the compression of the spring will increase after the screw and the limiting groove are engaged, and the elastic force will increase accordingly. The squeezing force of the two hoses on the elastic rubber ring will increase, thereby improving the connection strength. Conversely, the squeezing force of the two hoses on the elastic rubber ring will decrease, thereby weakening the connection strength.
[0015] 3. In this utility model, by setting the inner diameter of the elastic rubber ring to be no greater than the inner diameter of the hose, and the outer diameter of the elastic rubber ring to be no less than the outer diameter of the hose, it is possible to ensure that the elastic rubber ring fills the joint of the two hoses, thereby increasing the contact area between the elastic rubber ring and the hose and thus improving the sealing effect. The setting of the annular groove facilitates the connection and positioning of the elastic rubber ring and the hose, preventing the elastic rubber ring from shifting or falling off, and further improving the sealing effect.
[0016] 4. In this utility model, the rubber pad can increase the frictional resistance between the connector and the hose, prevent relative sliding between the connector and the hose, and protect the surface of the hose. Combined with the elastic protrusion, the frictional resistance between the connector and the hose can be further increased, preventing relative sliding between the connector and the hose.

[0029] This utility model provides a pipe connection device for lightweight wellpoint dewatering, such as... Figure 1 , Figure 2 As shown, the device includes two connecting seats 1, an adjusting mechanism, and an elastic rubber ring 3 installed at the joint of two hoses 2. The two connecting seats 1 are located on both sides of the elastic rubber ring 3 and are fixedly connected to the two hoses 2 respectively. The connecting seat 1 can be a two-half structure, with one end of the two halves hinged and the other end fastened with bolts. The two connecting seats 1 are connected by the adjusting mechanism. Under the action of the adjusting mechanism, the two hoses 2 move closer to each other and fit tightly against the two ends of the elastic rubber ring 3. To prevent the joint from loosening when the hoses 2 are moved, a detachable protective sleeve can be set between the two connecting seats 1. The protective sleeve consists of two arc-shaped plates that match the surface of the hoses 2 and are fixed together by screws.
[0030] In this embodiment, the two connecting seats 1, the adjusting mechanism and the elastic rubber ring 3 are arranged to tightly fit the ends of the two hoses 2 with the elastic rubber ring 3, ensuring sealing performance and facilitating disassembly and assembly.
[0031] In this utility model, preferably, such as Figure 1 , Figure 3 As shown, the adjusting mechanism includes a limiting plate 4, a screw 5, and an elastic component 6. The limiting plate 4 is fixedly installed on one of the connecting seats 1, and a limiting groove 7 is formed on the limiting plate 4. One end of the screw 5 is rotatably connected to the other connecting seat 1. The elastic component 6 is sleeved on the other end of the screw 5. When the other end of the screw 5 engages with the limiting groove 7 around the rotation point, the elastic component 6 is located on the side of the limiting plate 4 away from the rotation point and abuts against the limiting plate 4, thereby raising the two hoses 2. To adjust the connection strength, two sets of adjustment mechanisms can be symmetrically arranged. The elastic component 6 includes a connecting plate 61, a spring 62, a pressure plate 63, and a nut 64. The connecting plate 61, spring 62, and pressure plate 63 are all slidably sleeved on the screw 5. The two ends of the spring 62 are fixedly connected to the connecting plate 61 and the pressure plate 63, respectively. The nut 64 is threadedly connected to the screw 5 and fits against the pressure plate 63. When the screw 5 is engaged with the limiting groove 7, the connecting plate 61 abuts against the limiting plate 4 under the elastic force of the spring 62.
[0032] In this embodiment, the setting of the limiting plate 4, screw 5, elastic component 6, and limiting groove 7 allows for convenient fixing or disassembly of the two connecting seats 1, while also enabling the two hoses 2 to fit tightly together under the action of elasticity. Specifically, when it is necessary to fix the two connecting seats 1, simply rotate the screw 5 to engage with the limiting groove 7 on the limiting plate 4, and then attach the elastic component 6 to the side of the limiting plate 4 away from the other connecting seat 1. When it is necessary to disassemble the two connecting seats 1, simply use external force to separate the elastic component 6 from the limiting plate 4, and then rotate the screw 5 to disengage it from the limiting groove 7. The connecting plate 61, spring 62, and pressure... The arrangement of plate 63 and nut 64 allows the connecting plate 61 to be attached to or separated from the limiting plate 4 by the elastic force of spring 62, thereby enabling the connection and disassembly of the two hoses 2. At the same time, the initial elastic force of spring 62 can be freely adjusted to meet the adjustment of different forces between the two hoses 2. Specifically, when nut 64 moves towards the rotation point, the compression of spring 62 will increase after screw 5 engages with limiting groove 7, and the elastic force will increase accordingly. The squeezing force of the two hoses 2 on the elastic rubber ring 3 will increase, thereby improving the connection strength. Conversely, the squeezing force of the two hoses 2 on the elastic rubber ring 3 will decrease, thereby weakening the connection strength.
[0033] In this utility model, preferably, such as Figure 1 and Figure 2 As shown, the inner diameter of the elastic rubber ring 3 is not greater than the inner diameter of the hose 2, and the outer diameter of the elastic rubber ring 3 is not less than the outer diameter of the hose 2.
[0034] In this embodiment, by setting the inner diameter of the elastic rubber ring 3 to be no greater than the inner diameter of the hose 2 and the outer diameter of the elastic rubber ring 3 to be no less than the outer diameter of the hose 2, it can be ensured that the elastic rubber ring 3 fills the joint of the two hoses 2, thereby increasing the contact area between the elastic rubber ring 3 and the hose 2 and thus improving the sealing effect.
[0035] In this utility model, preferably, such as Figure 1 and Figure 2 As shown, both ends of the elastic rubber ring 3 are provided with annular grooves 8, which cooperate with the hose 2.
[0036] In this embodiment, the annular groove 8 facilitates the connection and positioning of the elastic rubber ring 3 and the hose 2, preventing the elastic rubber ring 3 from shifting or falling off, and further improving the sealing effect.
[0037] In this utility model, preferably, such as Figure 1 and Figure 2 As shown, a rubber pad 9 is installed between the connecting seat 1 and the hose 2; the end of the rubber pad 9 that contacts the hose 2 is provided with multiple elastic protrusions.
[0038] In this embodiment, the rubber pad 9 increases the frictional resistance between the connector 1 and the hose 2, preventing relative sliding between them and protecting the surface of the hose 2. Combined with the elastic protrusion, the frictional resistance between the connector 1 and the hose 2 is further increased, preventing relative sliding between them.
[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0040] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
