Since the two sides of the excavated trench are generally earthwork structures, if the earthwork structure encounters heavy rain or the soil structure itself is loose, it is easy to cause earthwork collapse. Therefore, support structures are usually required on both sides of the excavated trench to prevent earthwork collapse.

[0003] According to a patent document with an existing publication number of CN220152024U, a trench excavation protection device for water conservancy construction is disclosed, which includes a baffle, and an anti-collapse component is installed on the baffle, and the anti-collapse component includes a sliding sleeve, a sliding rod, a limit plate, a positioning pin, a limit plate, a first spring, a threaded sleeve, a screw and a rotating block. The four corners of the surface of the baffle are fixedly connected with the sliding sleeve, the sliding rod is slidably connected inside the sliding sleeve, and the two end surfaces of the sliding rod are fixedly installed with the limit plates. When the technical scheme is in use, the anti-collapse component is installed above the baffle, the positioning pin is first lifted to make the sliding rod break away from the restriction of the positioning pin, so that the sliding rod can slide in the sliding sleeve, and then the threaded sleeves at both ends are squeezed to both sides by rotating the rotating block on the screw, so that the two baffles squeeze the inner walls on both sides of the groove, which can avoid the lack of good support on both sides of the groove during construction in the groove, and the phenomenon of collapse occurs. With respect to the above technical scheme, although the scheme realizes collapse, it is impossible to adjust the support shape according to the shape of the groove, and it is impossible to quickly adjust according to the depth of the groove when in use.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a municipal trench construction protection device, including a protection device body, the protection device body includes a fixed seat 1 and a movable seat 2, support seats 6 are movably installed on both sides of the fixed seat 1 and the movable seat 2, openings 4 are opened on one side of the support seat 6, the movable seat 2 and the fixed seat 1, and a protrusion 5 is movably installed inside the opening 4, one end of the protrusion 5 is respectively welded to the support seat 6, the movable seat 2 and the fixed seat 1, and the protrusion 5 is installed inside the opening 4 through a rotating shaft, a connecting ear 7 is welded on the inner wall of the support seat 6, a connecting sleeve 8 is rotatably installed between the connecting ears 7, a threaded column 9 is welded on the connecting sleeve 8, a threaded tube 10 is rotatably installed between the threaded columns 9, and a reverse thread is opened on the threaded column 9. When the threaded tube 10 rotates, the threaded column 9 moves inward or outward at the same time, and the simultaneous movement of the threaded column 9 controls the expansion or contraction of the support seat 6.

[0022] In this embodiment, a fixed ear 11 is welded on the inner wall of the fixed seat 1 and the movable seat 2, a fixed sleeve 12 is rotatably installed inside the fixed ear 11, a positioning column 13 and a threaded rod 17 are respectively welded on the fixed sleeve 12, a rotating tube 14 is rotatably installed on one end of the threaded rod 17, one end of the positioning column 13 is movably installed inside the rotating tube 14, a baffle 16 is fixed inside the rotating tube 14, the baffle 16 movably cooperates with one end of the positioning column 13, a handle 18 is welded on the rotating tube 14, a cavity is opened inside the fixed seat 1, a support rod 15 is movably installed inside the cavity, one end of the support rod 15 is welded to the movable seat 2, the rotating tube 14 rotates and displaces on the threaded rod 17, and as the rotating tube 14 moves, the positioning column 13 is pushed to move to one side through the baffle 16 to complete the support of the fixed seat 1 and the movable seat 2.

[0023] When the device is in use, first place the support seat 6, the fixed seat 1 and the movable seat 2 inside the groove, rotate the threaded tube 10 between the bottom support seat 6, and the threaded tube 10 causes the support seat 6 to move outward synchronously and expand in the rotating state. The bottom support seat 6 generates a supporting force after contacting the inner wall of the groove, and the supporting force limits and fixes the support seat 6. The opening angle of the top support seat 6 is adjusted according to the shape of the top groove. The top threaded tube 10 is rotated to drive the threaded column 9 to rotate, and the threaded column 9 pushes the support seat 6 to move to both sides through the connecting sleeve 8. When the support seat 6 moves to both sides, the protrusion 5 is tilted on the fixed seat 1 through the rotating shaft, and the tilt squeezes the soil at the top of the groove to prevent the soil from entering the interior of the groove at a later time. The support seat 6 moves outward After opening, the support seat 6 drives the fixed seat 1 and the movable seat 2 to move to both sides through the protrusion 5. One side of the fixed seat 1 and the movable seat 2 slides horizontally inside the rotating tube 14 through the positioning column 13 to open. Later, the rotating tube 14 is selected, and the rotating tube 14 rotates on the threaded rod 17. The rotating tube 14 rotates and moves downward. The rotating tube 14 moves to one side of the positioning column 13. The rotating tube 14 supports the positioning column 13 through the baffle 16, so that the positioning column 13 provides support force for the fixed seat 1 and the movable seat 2. Before the fixed seat 1 and the movable seat 2 are fixed, the distance between the fixed seat 1 and the movable seat 2 is adjusted according to the depth of the groove. The fixed seat 1 and the movable seat 2 are connected and supported by the support rod 15, thereby expanding the support area of ​​the groove.
