Description

Technical Field

[0001] The invention relates to the technical field of hydropower stations, in particular to a mobile monitoring device for cave excavation. Background Art

[0002] During the excavation of the caverns of pumped storage power stations, blasting excavation is generally used.

[0003] When excavating in this way, there is a lack of monitoring measures for the tunnel face. In addition, in order to avoid the impact of blasting, the general monitoring method must be set up outside the safe distance of blasting, which is insufficient for monitoring the tunnel face and is easily obstructed.

[0004] Moreover, when encountering situations where the cavern turns or blasting occurs frequently, it is often necessary to adjust the monitoring position in a timely manner, which makes actual operation and maintenance very difficult.

[0005] The existing cave excavation monitoring has the following problems:

[0006] 1. In the cavern blasting operation, there is a problem of insufficient lighting, and the environment cannot be effectively identified;

[0007] 2. The monitoring of the face is not strong enough. General monitoring equipment cannot see the face clearly, is easily blocked and requires frequent follow-up of the position. Summary of the invention

[0008] The object of the present invention is to provide a mobile monitoring device for cavern excavation, which has the advantages of sufficient lighting and sufficient monitoring of the tunnel face.

[0009] The technical solution of the present invention is: a mobile monitoring device for cave excavation, including a trolley, a distribution box arranged on the trolley, a bracket vertically arranged on the trolley, a lighting unit mounted on the top of the bracket, a monitoring unit horizontally arranged on the top of the bracket and a wireless unit detachably arranged on the bracket.

[0010] In the aforementioned mobile monitoring device for cave excavation, the lighting unit is arranged on the top of the bracket via a rotatable electric rotating seat.

[0011] In the aforementioned mobile monitoring device for cave excavation, the monitoring unit is connected to the bracket through a support rod, and the monitoring unit is installed at the bottom of the end of the support rod; the monitoring unit adopts a rotatable and adjustable ball camera or pan / tilt camera.

[0012] In the aforementioned mobile monitoring device for cave excavation, the trolley is a two-wheeled handcart, and an insulating pad is provided on the handrail of the trolley.

[0013] In the aforementioned mobile monitoring device for cave excavation, the distribution box is a three-level distribution box, which is equipped with multiple cables, plugs and circuit breakers to meet the power demand.

[0014] In the aforementioned mobile monitoring device for cave excavation, the bracket is an electric telescopic bracket, which is arranged on a trolley and located at the rear side of a distribution box; an insulating partition is provided between the bracket and the distribution box; and a fixed base for installing the bracket is provided on the trolley.

[0015] In the aforementioned mobile monitoring device for cave excavation, auxiliary wheels are provided at the bottom of the front side of the cart, and a power-assisting mechanism linked to the wheels of the cart is provided at the bottom of the cart.

[0016] Compared with the prior art, the power distribution box, lighting unit and monitoring unit of the present application are integrated and arranged together on a trolley which is easy to move. After installation, the trolley can be pushed to any location in the cave, so that it can be pushed to the place where the lighting is maximized, which is convenient for lighting;

[0017] At the same time, the monitoring unit on the trolley is close to the palm face, and can perform remote monitoring, data push and remote operation through the matching wireless equipment.

[0018] Therefore, the present invention has the advantages of sufficient lighting and sufficient monitoring of the tunnel face.

[0019] The further distribution box can also supply power to the working face to meet the power demand of construction. BRIEF DESCRIPTION OF THE DRAWINGS
