Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of thermal construction, and particularly relates to a sealing device applied to a heat supply pipeline under construction. Background Art
[0002] When encountering heavy rain, the foundation pit of the heat supply pipeline under construction often has accumulated water. At this time, if the open end of the heat supply pipeline under construction is not blocked, large particle stones, sundries, dirt, etc. will enter the interior of the heat supply pipeline under construction, causing the pipeline to be clogged. After the construction resumes, the pipeline needs to be cleaned. The cleaning process not only consumes time and affects the construction period, but also is not easy to clean for some thinner pipelines. If the cleaning is not thorough, it will affect the subsequent heat supply effect.
[0003] Currently, to solve this problem, the open end of the pipeline is often blocked. Although blocking can effectively prevent large particle stones, sundries, dirt, etc. from entering the pipeline, the accumulated water will also make the hollow pipeline in a floating state. As Figure 15 shown, one end of the heat supply pipeline under construction is often fixed. When the pipeline is affected by the buoyancy force, the free end of the pipeline will deflect upward, thus damaging the welded joint that has been welded. Content of the Utility Model
[0004] In view of the above problems, a sealing device applied to a heat supply pipeline under construction provided by this application can not only immerse the pipeline in water to prevent floating, but also prevent large particle stones, sundries, dirt, etc. from entering the pipeline.

[0007] A push-pull rod is slidably arranged in the installation cylinder;
[0008] On one side of the filter screen, a plurality of tightening mechanisms arranged radially around the push-pull rod are provided;
[0009] The tightening mechanism includes a tightening block, and a first connecting rod and a second connecting rod are hinged on the tightening block. One end of the first connecting rod facing away from the tightening block is hinged to the installation cylinder or the filter screen, and one end of the second connecting rod facing away from the tightening block is hinged to the push-pull rod;
[0010] A locking mechanism for restricting the axial sliding of the push-pull rod relative to the installation cylinder is arranged between the push-pull rod and the installation cylinder.
[0011] Further, the locking mechanism includes an elastic member disposed between the mounting cylinder and the push-pull rod, and the elastic member is configured to prevent the end of the push-pull rod facing away from the jacking mechanism from approaching the mounting cylinder.
[0012] Further, the elastic member is a spring sleeved on the push-pull rod, a jacking ring is disposed on the push-pull rod, and the spring abuts against the jacking ring.
[0013] Further, the filter screen includes a mounting portion having a planar structure, and a tapered portion extending toward the side away from the jacking mechanism is provided at the edge of the mounting portion.
[0014] Further, the locking mechanism includes a jacking ring disposed on the push-pull rod, and the jacking ring is located on the side of the filter screen facing away from the jacking mechanism. A spring is sleeved between the filter screen and the jacking ring on the push-pull rod.
[0015] Further, the jacking ring is fixedly connected to the push-pull rod in a detachable manner.
[0016] Further, a baffle is provided on the end face of the end of the push-pull rod facing away from the jacking mechanism.

[0042] In order to enable those skilled in the art of this technology to better understand the technical solutions in this application, the following will describe the technical solutions in the embodiments of this application in detail with reference to the accompanying drawings in the embodiments of this application. The described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of this application.
[0043] For the convenience of description, a coordinate system is now defined as Figure 1 shown, with the left-right direction as the horizontal direction, the front-back direction as the longitudinal direction, and the up-down direction as the vertical direction.
[0044] Embodiment 1
[0045] As Figure 1 , Figure 4 , Figure 8 and Figure 9 shown, a sealing device applied to a heating pipe under construction includes a filter screen 1. An installation cylinder 11 vertically penetrating the filter screen 1 is arranged at the geometric center of the filter screen 1, and the installation cylinder 11 is fixedly connected to the filter screen 1.
[0046] As a specific implementation method, in this embodiment, the installation cylinder 11 is fixedly connected to the filter screen 1 by welding.
[0047] A push-pull rod 2 coaxially arranged with the installation cylinder 11 is arranged in the installation cylinder 11. The push-pull rod 2 forms a guiding fit with the installation cylinder 11, and the push-pull rod 2 can axially slide relative to the installation cylinder 11 under the guiding action of the installation cylinder 11.
[0048] On one side of the filter screen 1 (the rear side of the filter screen 1 according to the Figure 1 shown coordinate system), a number of tightening mechanisms are provided, and the number of the tightening mechanisms is evenly arranged radially around the push-pull rod 2.
[0049] As a specific implementation manner, three tightening mechanisms are provided at the rear side of the filter net 1 in this embodiment, and the three tightening mechanisms are evenly arranged radially around the push rod 2.
[0050] The tightening mechanism includes a tightening block 31, a first connecting rod 32 and a second connecting rod 33. One end of the first connecting rod 32 is hinged to one end of the tightening block 31 facing the filter net 1, and the other end of the first connecting rod 32 is hinged to the mounting cylinder 11 or the filter net 1. As a specific implementation manner, as Figure 5 shown, in this embodiment, the other end of the first connecting rod 32 is hinged to a first ear plate 12 provided on the mounting cylinder 11. One end of the second connecting rod 33 is hinged to the end of the tightening block 31 facing away from the filter net 1, and the other end of the second connecting rod 33 is hinged to the end of the push rod 2 facing away from the filter net 1. As a specific implementation manner, as Figure 6 shown, in this embodiment, a second ear plate 21 is provided at the end of the push rod 2 facing away from the filter net 1, and the other end of the second connecting rod 33 is hinged to the second ear plate 21. The lengths of the first connecting rod 32 and the second connecting rod 33 are equal, and the triangle formed by the first connecting rod 32, the second connecting rod 33 and the push rod 2 is an acute triangle. When the push rod 2 is pulled back and forth, the tightening block 31 will move away from or close to the push rod 2 under the action of the first connecting rod 32 and the second connecting rod 33.
[0051] As a specific implementation manner, as Figure 7 and Figure 10 shown, in this embodiment, two third ear plates 311 are provided on the side of the tightening block 31 facing the push rod 2. The first connecting rod 32 is hinged to the third ear plate 311 on the side close to the filter net 1, and the second connecting rod 33 is hinged to the third ear plate 311 on the side far from the filter net 1.
[0052] A locking mechanism for restricting the axial sliding of the push rod 2 relative to the mounting cylinder 11 is provided between the push rod 2 and the mounting cylinder 11.
[0053] The locking mechanism includes an elastic member, and the elastic member is provided between the mounting cylinder 11 and the push rod 2 for preventing the end of the push rod 2 facing away from the tightening mechanism from approaching the mounting cylinder 11.
[0054] . As a specific implementation manner, as Figure 2 and Figure 3As shown, at one end of the push rod 2 facing away from the tightening mechanism, a tightening ring 41 is provided. The elastic member is a spring 42 sleeved on the push rod 2. One end of the spring 42 abuts against the mounting cylinder 11, and the other end of the spring 42 abuts against the tightening ring 41.
[0055] In this way, when installing a sealing device for a heating pipeline under construction provided by the present application, first, the tightening mechanism part is inserted into the pipeline 6 until the filter net 1 abuts against the end face of the pipeline 6. Then, the push rod 2 is pushed towards one side of the pipeline 6, so that the tightening block 31 moves towards the side away from the push rod 2 under the action of the first connecting rod 32 and the second connecting rod 33 until the tightening blocks 31 are all tightened against the side wall of the pipeline 6, that is, in the states as shown in Figure 13 and Figure 14 . Then, the locking mechanism is locked. At this time, the tightening block 31 is tightened against the side wall of the pipeline 6, and under the action of friction, the entire sealing device cannot be pulled out of the pipeline 6, and the sealing device can be firmly fixed at the open end of the pipeline 6. Thus, the installation of the entire sealing device is completed.
[0056] It can be seen from the above installation process that providing the tightening force of the tightening mechanism by the spring 42 also has an advantage that no tools are required for installation and disassembly. As shown in Figure 9 , when disassembling, only one hand holds the mounting cylinder 11, and the other hand pushes the push rod 2 inward to retract the tightening block 31 of the tightening mechanism, and then the entire sealing device can be taken out. Similarly, when installing, one hand holds the mounting cylinder 11, and the other hand pushes the push rod 2 inward to retract the tightening block 31 of the tightening mechanism, and then one end of the tightening mechanism of the sealing device is inserted into the pipeline 6, and then the push rod 2 is released to complete the tightening installation.
[0057] Furthermore, as shown in Figure 7 and Figure 10 , at one end of the first connecting rod 32 facing the tightening block 31, a first tooth-shaped structure 321 is provided. At one end of the second connecting rod 33 facing the tightening block 31, a second tooth-shaped structure 331 is provided. The first tooth-shaped structure 321 and the second tooth-shaped structure 331 are meshed with each other. The angle B between the first connecting rod 32 and the push rod 2 is equal to the angle A between the second connecting rod 33 and the push rod 2. By providing the first tooth-shaped structure 321 and the second tooth-shaped structure 331, the first connecting rod 32, the second connecting rod 33 and the tightening block 31 can move along a fixed movement track, so that the tightening block 31 is always in a state parallel to the push rod 2.
[0058] Furthermore, as shown in Figure 1 , Figure 4 andFigure 8 As shown, the filter screen 1 includes a mounting portion having a planar structure. The mounting portion has a circular structure, and a tapered portion extending toward the side of the back-to-back tightening mechanism is provided at the edge of the mounting portion. The tapered portion has a tapered structure, and the diameter gradually increases in a direction away from the mounting portion. The filter screen 1 as a whole has a frustum structure with a small end closed, a large end open, and the large end facing away from the side of the tightening mechanism.
[0059] As a specific embodiment, in this embodiment, the filter screen 1 includes a body, and water passing holes are uniformly distributed on the body. The body is made of plates such as steel plates and stainless steel plates.
[0060] In this way, as Figure 11 and Figure 13 shown, the filter screen 1 can adapt to pipes 6 with different diameters, and the automatic centering can be conveniently achieved through the cooperation of the tapered portion and the open end of the pipe 6, so that the entire sealing device and the pipe 6 are in a coaxial state.
[0061] Furthermore, the tightening ring 41 is fixedly connected to the push rod 2 in a detachable manner.
[0062] As a specific embodiment, as Figure 2 and Figure 9 shown, in this embodiment, the tightening ring 41 is fixedly connected to the push rod 2 through a bolt assembly 43, and a plurality of mounting holes 22 for accommodating the bolts in the bolt assembly 43 are uniformly arranged along the axial direction on the push rod 2.
[0063] The reason for such a design is that due to the different diameters of the pipes 6, if the tightening mechanism tightens on the side wall of the pipe 6, the depth that the push rod 2 needs to be inserted is also different. When the diameter of the pipe 6 is larger, the depth that the push rod 2 needs to be inserted is smaller, and at this time, the spring 42 will have a larger space, and there may be a problem of insufficient elastic force. By setting the tightening ring 41 as a detachable structure, the elastic force of the spring 42 in the tightened state can be adjusted by adjusting the position of the tightening ring 41, so as to ensure that the tightening mechanism can reliably tighten on the side wall of the pipe 6.
[0064] Furthermore, in order to increase the friction force, as Figure 7 and Figure 10 shown, an anti-slip pad 34 made of rubber material is provided on the side of the tightening block 31 facing away from the push rod 2.
[0065] Furthermore, as Figure 2 shown, a baffle 5 is provided on the end face of the end of the push rod 2 facing away from the tightening mechanism, and the baffle 5 is fixedly connected to the push rod 2 through a screw 51.
[0066] Embodiment 2
[0067] The locking mechanism is a tightening stud arranged on the mounting cylinder 11 for tightening the push-pull rod 2. The tightening stud is threadedly connected to the mounting cylinder 11, and a handwheel is arranged at one end of the tightening stud facing away from the push-pull rod 2. The rest of the structure is the same as that of Embodiment 1.
[0068] Based on the embodiments provided in the present application, other embodiments obtained by those skilled in the art through means such as combination, disassembly, and recombination of the embodiments of the present application do not exceed the protection scope of the present application.
[0069] The above specific embodiments have detailed the purpose, technical solution, and beneficial effects of the embodiments of the present application.

That is, any modifications, equivalent replacements, improvements, etc. made on the basis of the embodiments of the present application shall be included in the protection scope of the embodiments of the present application.
