Description

Technical Field

[0001] This application relates to the field of engineering survey, and more particularly to a protective device for engineering survey. Background Technology

[0002] Engineering survey refers to the investigation and research of the geographical conditions of an engineering project, including surveying the project site and investigating the geology and hydrogeology of the construction site. It is an activity to map, explore, test and comprehensively evaluate the topography, geology and hydrology to meet the needs of feasibility studies, design and construction of engineering projects, and to provide corresponding results and data.

[0003] Chinese Patent Publication No. CN210768798U discloses a safety protection device for engineering geological exploration, including a base plate and side support rods. The upper surface of the base plate is fixedly connected to the side support rods and a fixing block. A fixing plate is snapped onto the surface of the fixing block. Both ends of the fixing plate are fixedly connected to the side support rods. A bottom anchor rod is threadedly connected to the center of the upper surface of the base plate. A side fixing rod is fixedly connected to the top of the side support rod. An arc-shaped bracket is snapped onto the inner wall of the side fixing rod. However, during the exploration process, it is usually necessary to explore the ground underground. Therefore, it is necessary to dig up the ground and have workers explore the bottom of the pit. However, soil or rocks are prone to fall into the pit, which makes it impossible to guarantee the personal safety of the workers at the bottom of the pit. Therefore, we propose a protective device for engineering exploration to solve the above problems. Utility Model Content

A rotating block 16 is fixedly connected to the outer surface of each connecting rod 15. A support frame 3 is fixedly connected to the bottom surface of each rotating block 16. A support leg 20 is placed inside each support frame 3. A base block 4 is fixedly connected to the bottom surface of each support leg 20. A placement frame 13 and a locking plate 6 are fixedly connected to the bottom surface of each of the two protective plates 1. A support plate 12 is placed inside the placement frame 13, and a lever is fixedly connected to the bottom surface of the support plate 12. 10. Two perforations 18 are opened on the side of the two protective plates 1 that are close to each other. The left end of the support plate 12 passes through the perforation 18 and extends into the interior of the clamping plate 6. Specifically, with the cooperation of multiple support frames 3 and support legs 20 provided in the device, the protective plates 1 can be supported, thereby providing safe protection for the workers at the bottom of the device. In addition, with the cooperation of the placement frame 13, clamping plate 6 and support plate 12, the two protective plates 1 at the top of the device can be supported, thereby ensuring the stability of the device. Therefore, this device solves the problem that soil or rocks are prone to fall in the pit, which makes it impossible to guarantee the personal safety of the workers at the bottom of the pit.

[0024] In this embodiment, each base block 4 has a locking block 9 fixedly connected to its outer surface, and two locking slots 7 are opened on the bottom surface of each of the two protective plates 1. Each locking block 9 is engaged with the locking slot 7. A lighting device 11 and a switch 8 are respectively installed on the bottom surface of one of the protective plates 1. The switch 8 is electrically connected to the lighting device 11 through a wire. Specifically, the lighting device 11 and the switch 8 can provide light for the survey personnel, and the locking slots 7 and the locking blocks 9 can fix each support frame 3.
