Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Please see Figures 1-3This utility model is a municipal pipeline protection device with an extendable length, including a protective mechanism 1 distributed in a left-right direction. The protective mechanism 1 includes an upper pipe 102 and a lower pipe 105 symmetrically distributed vertically. In actual use, the municipal pipeline passes through the space between the upper pipe 102 and the lower pipe 105, that is, the upper pipe 102 and the lower pipe 105 are protected by their cooperation. The upper pipe 102 is located above the lower pipe 105. Semi-annular plates 101 are fixed at both ends of the upper pipe 102 and the lower pipe 105. In use, the same height Two adjacent semi-annular plates 101 are brought into contact to reduce gaps and improve the protective effect. A connecting plate 104 is fixed to the front end of the upper tube 102 and the lower tube 105. A U-shaped plate 103 is provided inside the connecting plate 104. Screws 105a are fixed to the left and right sides of the lower end of the lower tube 105. A threaded sleeve 106 is connected to the external thread of the screw 105a. By rotating the threaded sleeve 106, the screw 105a moves up and down accordingly to adjust the angle and height of the semi-annular plates 101. The two semi-annular plates 101 at the same height can fit together to reduce gaps and improve the protective effect.

[0029] Specifically, a vertical plate 104a is fixed to the lower wall of the connecting plate 104 on the outer side of the U-shaped plate 103. A protrusion 103b is provided in the internal gap of the vertical plate 104a. The protrusion 103b is circular. The above arrangement allows the U-shaped plate 103 to rotate relative to the lower tube 105.

[0030] Bolts 103a are symmetrically arranged on the left and right sides of the upper wall of the U-shaped plate 103. The bolts 103a are threadedly connected to the U-shaped plate 103. The lower end of the bolt 103a abuts against the corresponding connecting plate 104. In this state, the upper tube 102 and the lower tube 105 are relatively fixed. By disengaging the bolts 103a from the corresponding connecting plate 104 and rotating the U-shaped plate 103 forward, the upper tube 102 and the lower tube 105 can be rotated relative to each other.

[0031] A positioning rod 101b is fixed on the left wall of the semi-annular plate 101 on the left side. A positioning hole 101a is opened on the semi-annular plate 101 on the right side at the position of the positioning rod 101b. The positioning rod 101b is inserted into the positioning hole 101a, so that the two protective mechanisms 1 are roughly in a coaxial state. The upper tube 102 is rotatably connected to the lower tube 105 through a hinge 102a.

[0032] A rotating rod 106a is fixed to the lower end of the screw sleeve 106. A base plate 108 is provided on the outside of the rotating rod 106a. The lower wall of the base plate 108 is in contact with the mounting platform. The rotating rod 106a is rotatably connected to the base plate 108 through a bearing. With the above configuration, the screw sleeve 106 can rotate relative to the base plate 108, so that the rotation of the screw sleeve 106 can drive the screw 105a to change its height.

[0033] Insert rods 107 are evenly inserted along the edge of the base plate 108. The lower end of the insert rod 107 is pointed, and the upper end of the insert rod 107 is fixed with an end plate 107a. Since municipal pipelines are mostly buried in the ground, by inserting the insert rods 107 into the soil, a stable connection between the base plate 108 and the ground can be achieved.

[0034] The operation process of this embodiment is as follows: First, the municipal pipeline is laid. Then, the protective mechanism 1 is operated. Specifically, the bolt 103a is rotated to move the bolt 103a upward. Then, the U-shaped plate 103 is rotated. Then, the front end of the upper pipe 102 is rotated upward. At this time, the protective mechanism 1 is operated to allow the municipal pipeline to pass through the lower pipe 105. Then, the upper pipe 102 is closed. Then, the U-shaped plate 103 is rotated. The bolt 103a is rotated and its lower end abuts against the connecting plate 104. At this time, the threaded sleeve 106 is rotated. Under the action of the screw 105a, the screw 105a and the threaded sleeve 106 move relative to each other, causing the positioning rod 101b to be on the same horizontal plane as the positioning hole 101a in the adjacent protective mechanism 1. At this time, the protective structure is operated to insert the positioning rod 101b into the positioning hole 101a in the adjacent protective mechanism 1. Then, the insertion rod 107 is operated to pass through the base plate 108 and be inserted into the ground.

[0035] Example 2

[0036] Please see Figure 1 , 2 4 and 5 are the second embodiment of this utility model. This embodiment is based on the previous embodiment, but differs from the first embodiment in that: a connecting mechanism 2 is provided on the outside of the two protective mechanisms 1 that are close to each other. The connecting mechanism 2 includes an upper hollow box 201 and a lower hollow box 202 that are symmetrically arranged. Both the upper hollow box 201 and the lower hollow box 202 are semi-circular. The semi-circular grooves opened in the upper hollow box 201 and the lower hollow box 202 are adapted to the corresponding semi-circular plate 101. The upper hollow box 201 and the lower hollow box 202 are located outside the corresponding semi-circular plate 101. A connecting rod 203 is inserted into the front end of the lower hollow box 202. The rear end of the connecting rod 203 is inserted into the interior of the front end of the upper hollow box 201. In this state, the upper hollow box 201 and the lower hollow box 202 are relatively fixed.

[0037] Specifically, the upper hollow box 201 is rotatably connected to the upper hollow box 201 via hinge 201a;

[0038] A baffle 203b is fixed to the front of the lower hollow box 202 corresponding to the outside of the connecting rod 203. The rear wall of the baffle 203b contacts the front end of the lower hollow box 202. An elastic element 204 is provided to the front of the baffle 203b corresponding to the outside of the connecting rod 203 to provide support for the baffle 203b. An L-shaped plate 202a is provided to the front end of the elastic element 204 corresponding to the outside of the connecting rod 203, so that the connecting rod 203 can only move in the back and forth direction. The L-shaped plate 202a is fixedly connected to the lower hollow box 202. A pinch block 203a is fixed to the front end of the connecting rod 203. By operating the pinch block 203a, the connecting rod 203 can be inserted into or detached from the upper hollow box 201.

[0039] The remaining structure is the same as in Example 1;

[0040] The operation process of this embodiment is as follows: After the two adjacent protective mechanisms 1 are connected, the connecting rod 203 is disengaged from the upper hollow box 201 by moving the pinch block 203a forward. At this time, the upper hollow box 201 is rotated and the lower hollow box 202 is positioned outside the mutually attached semi-annular plate 101. Then, the upper hollow box 201 is rotated in the opposite direction. At this time, the force on the pinch block 203a is released. Under the action of the elastic element 204, the rear end of the connecting rod 203 is inserted into the interior of the front end of the upper hollow box 201.
