Description

Technical Field

[0001] This application relates to the field of water conservancy and hydropower engineering technology, and in particular to a mobile power supply device for underground excavation projects. Background Technology

[0002] In the construction of water conservancy and hydropower projects, blasting is required to complete the construction of underground caverns.

[0003] Due to the complex construction conditions of underground caverns in water conservancy and hydropower projects, the geological conditions and surrounding rock are varied, and there is a high risk of large water inflows.

As a result, the temporary power supply arrangements during the excavation and support construction of underground caverns are quite complicated.

[0038] Currently, traditional sidewall wiring is used in underground cavern excavation and support construction to meet temporary power needs during the support process. However, temporary power lines are easily damaged or broken by flying rocks during excavation and blasting, posing numerous safety risks and compromising the safety of the construction.

[0039] To address the aforementioned issues, this application provides a mobile power supply device for underground excavation projects, which enables rapid deployment of temporary power during underground cavern construction, effectively reducing construction safety hazards.

[0045] See Figure 1-4 A mobile power supply device for underground excavation projects includes: a trolley frame 1, a fixed frame 2, a power distribution cabinet 3, a cable retractor 4, and a light panel 5.

[0046] The bottom of the cart frame 1 is equipped with wheels 101, and handles are installed on both sides of the cart frame 1.

[0047] Specifically: the wheel 101 is a rubber wheel 101.

[0048] In this embodiment, by equipping the trolley frame 1 with rubber wheels 101 and handles, it is possible to move flexibly in the underground cavern environment, making it convenient for workers to operate.
