Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pressure resistance of drainage pipes, in particular to a pressure resistance protection structure for municipal drainage pipes. Background Art
[0002] Drainage pipes refer to a system consisting of pipes and their ancillary facilities that collect and discharge sewage, wastewater and rainwater, including main pipes, branch pipes and pipes leading to treatment plants. Because the pipes are usually laid underground, they are easily damaged by the surrounding pressure.
[0003] Therefore, in order to prevent the pipeline from being crushed,
[0004] Therefore, a pressure-resistant protection structure for municipal drainage pipes in the prior art is disclosed with the publication number CN220727545U. The external rubber pad provides a layer of protection for the pipe body. When the first protective cover is subjected to pressure, it is deformed, and the first fixed block is subjected to downward pressure. The overall structure formed by the second buffer column and the second shock-absorbing spring partially offsets the impact force exerted on the first fixed block. The downward movement of the first fixed block causes the rotating plate to flip, so that the impact force is transmitted to the first buffer column and the first shock-absorbing spring. The first buffer column and the first shock-absorbing spring offset the remaining impact force, thereby protecting the pipe body. The prior art also provides a connecting mechanism to connect the ends of the first protective cover and the second protective cover.
[0005] However, because the first fixing block is fixed to the inner walls of the first protective sleeve and the second protective sleeve, the anti-pressure mechanism is non-detachably connected to the inner walls of the first protective sleeve and the second protective sleeve. Therefore, when the first protective sleeve and the second protective sleeve are installed on the surface of the pipe body using the connecting mechanism, the end of the second buffer column in the anti-pressure mechanism away from the inner wall of the first protective sleeve and the rubber pad on the outer wall of the pipe body are not fixedly connected, but are only fixed by the friction between the rubber pad. Therefore, when the first protective sleeve is greatly deformed, that is, the downward pressure on the first fixing block exceeds the friction between the second buffer column and the rubber pad, the second buffer column is likely to slip on the rubber pad. That is, the residual impact force that can be offset by the first buffer column at this time is small, resulting in some impact force still acting on the pipe body. Utility Model Content
[0006] The purpose of the utility model is to solve the problems existing in the prior art and to propose a pressure-resistant protection structure for municipal drainage pipes.
[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a pressure-resistant protection structure for municipal drainage pipes, comprising a pipe body, a rubber pad known to be installed on the outer wall of the pipe body, a protective cover, and several pressure-resistant mechanisms installed between the protective cover and the rubber pad, wherein two protective covers are symmetrically arranged, and two arc-shaped clamping blocks symmetrically distributed about the pressure-resistant mechanism and installed on the outer side of the rubber pad are arranged between the protective cover and the rubber pad, a long bolt is connected between the two first fixed blocks on one side of the pressure-resistant mechanism and the two arc-shaped clamping blocks, a plurality of sliders are slidably connected to the inner wall of the protective cover, a connecting column is provided through the side of the slider, and one end of the connecting column is fixedly connected to a plug block for plugging with the first fixed block on the other side of the pressure-resistant mechanism.
[0008] Preferably, the arc-shaped clamping block is arranged concentrically with the pipe body, and the inner wall of the arc-shaped clamping block is arranged to fit the outer wall of the rubber pad, and a fixing bolt threadedly connected to the outer wall of the rubber pad is provided through one of the arc-shaped clamping blocks.
[0009] Preferably, the two arc-shaped blocks are fixed to both sides of the opposite end surfaces of the two protective covers by bolts.
[0010] Preferably, the inner wall of the protective cover is fixedly connected with an arc-shaped track for slidingly installing a slider, and the side of the slider away from the pressure-resistant mechanism is threadedly connected with a nut for damping cooperation with the arc-shaped track.
[0011] Preferably, a curved rod is slidably connected between the plurality of inserting blocks in the protective cover, and the curved rod is concentric with the curved track and has the same arc.
[0012] Preferably, sliding grooves are provided on both sides of the outer wall of the protective cover, and both ends of the arc-shaped rod extend outward from the protective cover through the sliding grooves and are fixedly connected with sliding rings.
[0013] Preferably, the inner wall of the sliding ring is slidably connected to the outer wall of the protective cover and covers the sliding groove, and a positioning pin is connected between the sliding ring and the protective cover.
[0014] Compared with the prior art, the advantages and positive effects of the present invention are:
[0015] 1. In the present invention, the relative position of the first fixed block and the rubber pad in the anti-pressure mechanism can be achieved by providing two arc-shaped clamping blocks, and the position of the plug-in block is adjusted by providing a connecting column plugged into the slider. After the protective cover is installed, the plug-in block is slid back to be plugged into the first fixed block on the other side of the anti-pressure mechanism, so that the position of the first fixed block in the anti-pressure mechanism between the protective cover and the rubber pad can be fixed.
[0016] 2. In the present invention, the two arc-shaped clamping blocks are convenient for adjusting the position and number of the anti-pressure mechanism outside the rubber pad, and the position of the first fixed block on one side of the anti-pressure mechanism is fixed by a long bolt. By providing an arc track and a nut, the position of the slider is conveniently adjusted through the arc track, so that the slider is aligned with the position of the anti-pressure mechanism, and the position of the slider after position adjustment is fixed by rotating the nut against the arc track, and then the position of the first fixed block on the other side of the anti-pressure mechanism is fixed by using the inserted block in the fixed slider. Therefore, this solution facilitates adjustment of the number and installation interval of the anti-pressure mechanism according to the size of the pipeline body. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.
[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0024] like Figure 1-4As shown, a pressure-resistant protection structure for municipal drainage pipes includes a pipe body 3, a rubber pad 4 known to be installed on the outer wall of the pipe body 3, a protective cover 2 and several pressure-resistant mechanisms 5 installed between the protective cover 2 and the rubber pad 4. Two protective covers 2 are symmetrically arranged, and two arc-shaped clamping blocks 6 are symmetrically distributed about the pressure-resistant mechanism 5 and installed on the outer side of the rubber pad 4. Long bolts 13 are connected between the two first fixing blocks on one side of the pressure-resistant mechanism 5 and the two arc-shaped clamping blocks 6. By fixing the position of one of the arc-shaped clamping blocks 6 and then installing the other arc-shaped clamping block 6, the pressure-resistant mechanism 5 is placed between the two arc-shaped clamping blocks 6, and the long bolts 13 are used to penetrate the two arc-shaped clamping blocks 6 and the first fixing block known to be close to the rubber pad 4 in the pressure-resistant mechanism 5, and then by installing nuts, the relative position of the arc-shaped clamping block 6 movably connected to the rubber pad 4 and the arc-shaped clamping block 6 fixed on the rubber pad 4 can be fixed, and the two arc-shaped clamping blocks 6 can realize the pressure-resistant mechanism 5 close to the rubber The first fixing block of the pad 4 is fixed to the relative position of the rubber pad 4, and the inner wall of the protective cover 2 is slidably connected with several sliders 14. A connecting column 9 is provided on the side of the slider 14. One end of the connecting column 9 is fixedly connected to an insert block 11 for inserting into the first fixing block on the other side of the pressure-resistant mechanism 5. When in use, the position of the slider 14 is adjusted according to the position of the pressure-resistant mechanism 5, and then the connecting column 9 is used to slide in the slider 14 to the end face of the insert block 11 and insert it into the first fixing block on the side of the pressure-resistant mechanism 5 away from the rubber pad 4. The sliding of the insert block 11 and the inner wall of the protective cover 2 can prevent the insert block 11 from rotating. Similarly, in actual use, the connecting column 9 adopts a rectangular setting, which can prevent the connecting column 9 from rotating after fixing the position of the slider 14, and further prevent the insert block 11 from rotating. Therefore, when the positions of the slider 14, the connecting column 9 and the insert block 11 are fixed, the position of the first fixing block on the side of the pressure-resistant mechanism 5 away from the rubber pad 4 can be fixed, that is, it is ensured that the pressure-resistant mechanism 5 will not be offset on the surface of the rubber pad 4 due to excessive deformation during operation.
[0025] Further explanation of the arc-shaped clamping block 6: the arc-shaped clamping block 6 is arranged concentrically with the pipe body 3, and the inner wall of the arc-shaped clamping block 6 is arranged to fit the outer wall of the rubber pad 4. One of the arc-shaped clamping blocks 6 is provided with a fixing bolt 7 threadedly connected to the outer wall of the rubber pad 4. The two arc-shaped clamping blocks 6 are fixed to the opposite end faces of the two protective covers 2 by bolts. The fixing bolt 7 is used to fix one of the arc-shaped clamping blocks 6 to the outer wall of the rubber pad 4, and the bolts can be used to achieve convenient and detachable installation of the two arc-shaped clamping blocks 6.
[0026] In order to adjust the position of the plug 11, it is convenient to adjust according to the number and installation position of the anti-pressure mechanism 5: the inner wall of the protective cover 2 is fixedly connected with an arc track 8 for slidingly installing a slider 14, and the slider 14 is threadedly connected to the side away from the anti-pressure mechanism 5 with a nut 10 for damping cooperation with the arc track 8. By sliding the slider 14 in the arc track 8, the position of the connecting column 9 and the plug 11 can be adjusted synchronously, which facilitates appropriate adjustment according to the installation number, position, and distribution spacing of the anti-pressure mechanism 5. After the position of the slider 14 is adjusted, by rotating the nut 10, the end face of the nut 10 is tightly pressed against the side of the arc track 8, and the friction is increased by increasing the pressure, so that the slider 14 can be fixed to the side of the arc track 8. In addition, in order to increase the friction, you can also choose to install a silicone gasket on the end face of the nut 10.
[0027] In order to prevent the position interference of the plug block 11 and the anti-pressure mechanism 5 during installation: a curved rod 12 is slidably connected between the several plug blocks 11 in the protective cover 2. The curved rod 12 is concentric with the curved track 8 and is set with the same arc. Slide grooves 15 are provided on both sides of the outer wall of the protective cover 2. Both ends of the curved rod 12 extend to the outside of the protective cover 2 through the slide grooves 15 and are fixedly connected with a sliding ring 1. The inner wall of the sliding ring 1 is slidably connected to the outer wall of the protective cover 2 and covers the slide groove 15. A positioning pin 16 is connected between the sliding ring 1 and the protective cover 2. When the position of the plug block 11 is adjusted, it will slide on the curved rod 12 accordingly, and after the positions of the several sliders 14 are adjusted, the slider 14 can be adjusted by toggling the slider. The dynamic ring 1, under the driving action of the arc rod 12, realizes that several plug blocks 11 drive the connecting column 9 to slide relative to the slider 14, so that the plug block 11 is misaligned with the first fixed block on the side of the anti-pressure mechanism 5 away from the rubber pad 4, so that the two protective covers 2 can be smoothly docked and fixed on the pipe body 3. After the position of the protective cover 2 is fixed, the sliding ring 1 can be reversed to make the arc rod 12 slide along the slide groove 15, while sliding, driving the plug block 11 and the connecting column 9 to slide relative to the slider 14 until the plug block 11 is plugged into the first fixed block on the side of the anti-pressure mechanism 5 away from the rubber pad 4, thereby achieving the position fixation of the first fixed block in the anti-pressure mechanism 5.
[0028] Working principle: According to the construction requirements, an appropriate number of pressure-resistant mechanisms 5 are selected, and then the interval angle between two adjacent pressure-resistant mechanisms 5 is calculated according to the diameter of the rubber pad 4 on the surface of the pipe body 3. According to the calculated interval angle, the slider 14 is pushed to slide on the arc track 8, so that the installation position and angle of the connecting column 9 on the slider 14 and the plug-in block 11 on its end face correspond to the installation interval of the pressure-resistant mechanism 5, and several pressure-resistant mechanisms 5 are fixed on the rubber pad 4 using two arc-shaped clamping blocks 6. Then, the sliding ring 1 is moved so that the plug-in block 11 is misaligned with the first fixed block on the side of the pressure-resistant mechanism 5 away from the rubber pad 4, so that the two protective covers 2 can be smoothly docked and installed, and then the sliding ring 1 is moved in the opposite direction. Under the driving action of the arc rod 12, the plug-in block 11 is reset to be plugged into the first fixed block on the side of the pressure-resistant mechanism 5 away from the rubber pad 4, and finally, the positioning pin 16 is used to fix the relative position of the sliding ring 1 and the protective cover 2.
