DETAILED DESCRIPTION

[0025] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] like Figure 2 to Figure 6As shown, this embodiment proposes an anti-collapse device for municipal water supply and drainage construction, including a lower cover tube 1 and an upper cover tube 2, two limit blocks 3 for limiting the surface of the water pipe are fixedly connected to the inner wall of the lower cover tube 1 and the upper cover tube 2, respectively, a water pipe 5 is connected between the lower cover tube 1 and the upper cover tube 2, and the outer cylindrical surface of the water pipe 5 is respectively in contact with the surface of each limit block 3, and a plurality of clamping grooves 11 and limit holes 21 for increasing the connection between the lower cover tube 1 and the upper cover tube 2 are respectively opened on the lower cover tube 1 and the upper cover tube 2, so as to increase The fastening component 4 of the contact area between the device and the ground is connected between the limiting hole 21 and the clamping groove 11. The fastening component 4 can increase the connection between the device and the ground by increasing the contact area between the device and the ground, and the clamping sequence is that after the device and the ground are clamped, the lower cover tube 1 and the upper cover tube 2 clamp the water pipe 5, so that when the water pipe 5 needs maintenance or replacement, the upper cover tube 2 can be removed without affecting the connection strength between the device and the ground, which is convenient for the operator to work and reduces labor intensity.

[0028] like Figure 3 to Figure 6 As shown, the fastening assembly 4 includes a clamping column 45, which is clamped and slidably engaged with the inner wall of the clamping groove 11, a receiving plate 44 is fixedly connected to the lower end of the clamping column 45, the receiving plate 44 is hinged to a plurality of flip plates 43, each clamping plate 42 is fixedly connected to an end of each flip plate 43 away from the clamping plate 44, the clamping column 45 slides and abuts against the clamping column 46, the bottom plate 41 is fixedly connected to the lower end of the clamping column 46, a plurality of clamping blocks 48 are fixedly connected to the bottom plate 41, each clamping block 48 is hinged to each flip plate 43, and a clamping nut 47 is sleeved on the upper end of the clamping column 46. By rotating the clamping nut 47, the lower cover tube 1 and the upper cover tube 2 can be clamped to the water pipe 5 together, and each flip plate 43 can be flipped upward to increase the contact area between the device and the ground, thereby increasing the connection between the device and the land, enabling the device to cope with more vibration forces, and thereby enabling the device to cope with more impact forces, thereby making the device more stable.

[0029] like Figure 4 and Figure 5 As shown, the external thread 461 is provided on the cylindrical surface of the upper end of the clamping column 46, and the upper end of the clamping column 46 is threadedly connected with the clamping nut 47, and the keyway 462 is provided on the clamping column 46, and the key block 452 is fixedly connected to the inner wall of the clamping column 45, and the key block 452 abuts against the inner wall of the keyway 462, and the clamping nut 47 can be screwed in. Under the action of the threaded connection, the clamping column 46 can remain stable and upward without rotating, thereby driving the components cooperating with the clamping column 46 to move. After the device is completely clamped to the ground, continuing to tighten the clamping nut 47 can make the lower cover tube 1 and the upper cover tube 2 completely clamp the water pipe 5, which is also convenient. When the water pipe 5 needs to be replaced and maintained, the upper cover tube 2 can be removed without affecting the fixation of the device to the ground, and then the water pipe 5 can be removed, thereby saving the maintenance time of the water pipe 5.

[0030] like Figure 3 and Figure 4 As shown, the step groove 451 is provided at the upper end of the clamping column 45 , and the step groove 451 abuts against the inner wall of the limiting hole 21 . The step groove 451 is used to calibrate and position the upper cover tube 2 so that the lower cover tube 1 and the upper cover tube 2 can be installed better.

[0031] like Figure 4 As shown, the limit groove 431 is opened on the flip plate 43, and the clamping block 48 abuts against the inner wall of the limit groove 431, so that when the bottom plate 41 moves upward, the bottom plate 41 will move with the clamping block 48, and then the flip plate 43 will flip up with the movement of the clamping block 48, thereby increasing the contact area between the flip plate 43 and the ground, thereby increasing the friction between the device and the ground. After the flip plate 43 is fully opened, the ground is compacted to make the device more stable in limiting and fixing the water pipe 5.

[0032] like Figure 4 and Figure 6 As shown, several sheaths 410 are fixedly connected to the lower end of the receiving plate 44. The sheaths 410 cover the components inside the sheaths 410 to protect the components. At the same time, when the conical block 49 is at the lowest point, the outer busbar of the sheath 410 can be parallel to the busbar of the conical block 49, so that the components cooperating with the conical block 49 can be more easily sunk into the ground, which reduces the labor intensity of the operator to a certain extent.

[0033] like Figure 3 and Figure 5 As shown, the conical block 49 is fixedly connected to the lower end of the base plate 41. The conical block 49 reduces the contact area when the base plate 41 first contacts the ground, so that the base plate 41 can sink into the ground more easily, further reducing the labor intensity of the operator.

[0034] like Figure 2 and Figure 3 As shown, a plurality of slots 31 are provided on the limit block 3, so that the limit block 3 is close to the surface of the water pipe 5, and supports the water pipe 5 while reducing the contact area between the limit block 3 and the cylindrical surface of the water pipe 5, so that under the same action, a greater pressure can be generated, and the connection between the limit block 3 and the water pipe 5 is tighter. At the same time, the water temperature in the water pipe 5 will be transmitted through the pipe wall, and the water temperature will be affected by the external temperature to produce a certain temperature difference, and then this part of the temperature difference will affect the thermal expansion and contraction of the limit block 3. The slots 31 are used to prevent the limit block 3 from being damaged easily, thereby increasing the service life of the limit block 3.

[0035] The working principle of this embodiment is:

[0036] First, adjust the bottom plate 41 on the fastening assembly 4 to the lowest position, then snap-fit ​​and slide each snap-fit ​​groove 11 on the lower cover tube 1 with the snap-fit ​​column 45 of each fastening assembly 4, and after confirming the position of the water pipe 5, apply force to the snap-fit ​​column 45, so that the snap-fit ​​column 45 gradually sinks into the ground along with the conical block 49, and after sinking to a certain distance, tamp the sunken ground surface, so that the water pipe 5 is then placed on the limit block 3, and then the upper cover tube 2 is limited along the clamping column 46, and when the upper cover tube 2 is placed, the existing force rod is used to The tool is used to tighten the clamping nut 47. Under the tightening action of the clamping nut 47, the clamping column 46 follows the abutment action of the key block 452 and the inner wall of the key groove 462. The lower side of the clamping nut 47 contacts the surface of the upper cover tube 2. The clamping column 46 will move upward, thereby driving the bottom plate 41 to move upward, so that the flip plate 43 is turned outward, increasing the connection and contact between the device and the ground. After the device is completely clamped with the ground, the clamping nut 47 is further tightened, so that the lower cover tube 1 and the upper cover tube 2 can jointly clamp the water pipe 5 to a limited position.

[0037] When the water pipe 5 needs to be removed or replaced, the clamping nut 47 is unscrewed in the reverse direction using the existing force rod tool. Because the clamping nut 47 is no longer limited by the upper cover tube 2 when unscrewing in the reverse direction, the clamping nut 47 can be gradually unscrewed from the clamping column 46, and then the upper cover tube 2 and the water pipe 5 can be removed and replaced.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
