[0002] During the construction of water conservancy and hydropower projects, accidents may occur when people enter some dangerous areas such as edges, threatening their health. At this time, guardrails are usually used to isolate these areas to ensure the safety of personnel.

[0003] In the prior art, a Chinese utility model patent document with authorization announcement number CN217106468U discloses a safety protection device for water conservancy project construction, wherein a mounting column is fixedly installed on the ground through a base, and a mounting block for connecting a cross bar is fixedly provided on the outer side of the mounting column. When the mounting column is offset around its axis during installation, the mounting blocks between two adjacent mounting columns will not correspond. At this time, the cross bar cannot be installed between the two mounting columns, and the mounting column needs to be disassembled and adjusted in angle before installing the cross bar. After the cross bar is first installed between the two mounting columns, the mounting column is fixedly installed on the ground. The mounting column with the cross bar has a large mass and is not convenient for installation.

[0004] Therefore, it is necessary to design a safety protection device for water conservancy and hydropower engineering construction that can adjust the angle of the installation block between the installation column and the horizontal railing to improve the installation convenience to solve the current technical problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a safety protection device for construction of water conservancy and hydropower engineering projects, which can adjust the angle of a mounting block between a mounting column and a horizontal railing to improve installation convenience.

[0007] Preferably, the crossbar assembly has an intermediate tube body, and side tube bodies are slidably arranged inside the two ends of the intermediate tube body, and the end of the side tube body facing away from the intermediate tube body is detachably fixedly connected to the mounting block, and the end of the side tube body close to the intermediate tube body is provided with a locking mechanism for locking or releasing it to the intermediate tube body.

[0008] Preferably, the locking mechanism has a screw rod fixedly arranged on the outside of one end of the side tube body close to the intermediate tube body, a sliding groove matching the screw rod is opened on the side of the intermediate tube body, the screw rod is slidably arranged inside the sliding groove, and a nut for locking or releasing the intermediate tube body and the side tube body is assembled on the screw rod on the outside of the intermediate tube body.

[0009] Preferably, an external thread connector is provided on one end of the side tube body away from the middle tube body, and an internal thread hole matching the external thread connector is provided on the mounting block.

[0010] Preferably, an upper stop edge is fixedly provided on the support column above the rotating sleeve, and a lower stop edge is fixedly provided on the support column below the rotating sleeve.

[0011] Preferably, the lower end of the anchor rod has a cone head.
