Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel detection, in particular to a searchlight for tunnel detection. Background Art

[0002] A tunnel refers to an underground passage or other long building built in the ground. The purpose of a tunnel is to provide transportation and pedestrian passages to meet the requirements of smooth traffic routes. In order to ensure the safe operation of the tunnel and extend its service life, the constructed tunnel needs to be inspected. By continuously monitoring various parameters of the internal and external environment of the tunnel, safety hazards and structural problems can be discovered in a timely manner, so that corresponding maintenance and repair measures can be taken. In addition, due to the poor light inside the tunnel, staff are required to configure corresponding searchlights to illuminate the interior of the tunnel, which makes it more convenient for staff to conduct tunnel inspections inside the tunnel.

[0003] A search revealed patent publication number CN215259309U, which discloses a tunnel inspection searchlight. This patent relates to the field of tunnel inspection technology. The searchlight comprises a main body, a rear cover fixedly connected to the exterior surface of the main body, a hanging ring fixedly connected to the exterior surface of the rear cover, a USB port internally disposed within the rear cover, and a dust cover movably connected to the bottom end of the rear cover. The light is constructed using a support column, a base, a first strap, a sub-clasp, a second strap, a female buckle, a first groove, a spring, a push plate, a clamping block, and a clamping slot. By tightening the first and second straps and then snapping the sub-clasp and female buckle together, other operations can be performed simultaneously while the light is illuminated. This design is simple and efficient. The main body, upper base, rotating shaft, and lower base are connected by rotating the shaft, which allows the main body to rotate easily, enabling multi-angle illumination, avoiding blind spots, and improving the light's operational flexibility.

[0004] However, it still has the following disadvantages in actual use:

[0005] The above-mentioned searchlight for tunnel inspection has a first groove provided inside the support column, a spring fixedly connected to the inner wall of the first groove, a push plate fixedly connected to one end of the spring, a clamping block fixedly connected to the outer surface of the push plate, and a clamping groove provided inside the mounting plate. If the searchlight needs to be separated from the base, the push plate is toggled, and then the spring and the clamping block are driven to move, so that the clamping block pops out of the clamping groove, and the support column can be popped out of the mounting plate, thereby realizing flexible disassembly of the searchlight. A second groove is provided inside the mounting plate and located on one side of the clamping groove, and a bolt is movably connected inside the second groove. However, multiple first grooves are provided inside the support column, and multiple push plates need to be pulled, which increases the number of operating steps when disassembling and assembling the searchlight and increases the workload of the staff when disassembling and assembling the searchlight.

[0006] 2. In the above-mentioned searchlight for tunnel inspection, the bottom end of the searchlight body is fixedly connected to an upper base plate, and the bottom end of the upper base plate is fixedly connected to a rotating shaft. When it is necessary to change the lighting angle, the rotating shaft can be rotated to drive the searchlight body to rotate, which can make the searchlight easy to rotate in different directions, thereby realizing multi-angle lighting, avoiding lighting blind spots, and improving the flexibility of the searchlight. However, it is inconvenient to lock the position of the searchlight after rotation adjustment, resulting in insufficient lighting stability inside the tunnel, affecting tunnel inspection, and it is inconvenient to judge the rotation angle of the searchlight, which increases the time for adjusting the searchlight angle.

[0007] To this end, we provide a searchlight for tunnel inspection to solve the above problems. Utility Model Content
