[0002] In water conservancy projects, in order to convey water or discharge flood, a closed water conveyance tunnel is often excavated through mountains, which is called a hydraulic tunnel. According to its different tasks, it can be divided into a water release tunnel and a flood discharge tunnel. The water release tunnel is used to release the water required for irrigation, power generation, water supply, etc. from the reservoir; the flood discharge tunnel is used to cooperate with the spillway to discharge part of the flood, discharge the tail water of the hydropower station, empty the reservoir for the need of overhauling the hub buildings or for war preparations, and discharge sediment, etc. With the development of society, the old tunnels are facing renovation, and the renovated water conservancy tunnels need to be blasted with explosive packages, and the explosive packages are placed in a small transportation tool. Then, a kayak is used to drive the transportation tool to transport the explosive package to the destination. When the water flow in the transportation river is rapid, it will cause huge swings of the transportation device, and then the explosive package on the transportation tool will fall into the water, resulting in an increase in the cost of blasting the tunnel.

[0003] In the prior art, the transportation devices for blasting in water conservancy tunnels disclosed in the utility model patents with the publication numbers of CN209023655U and CN210242590U both adopt the method of buoyancy plates plus buffer shock absorption to prevent the explosive packages on the transportation tool from falling into the water, but they cannot effectively prevent tipping, and there is still a risk of collision and tipping during transportation.

[0025] Specifically, in this embodiment, the floating ship base 1 has a boat-shaped structure. Compared with a floating board, the boat-shaped floating ship base 1 has better stability during transportation in a water conservancy tunnel.

[0026] The balance mechanism includes a first balance ring 2, a second balance ring 5 and a third balance ring 6. Among them, the first balance ring 2 is vertically fixed on the floating ship base 1. The second balance ring 5 is arranged inside the first balance ring 2, and first rotating shafts 7 are arranged between the upper and lower ends of the second balance ring 5 and the first balance ring 2. The second balance ring 5 is rotationally connected to the first balance ring 2 through the first rotating shafts 7. Specifically, bearings are fixedly embedded in both the first balance ring 2 and the second balance ring 5, and the two ends of the first rotating shaft 7 are respectively connected to the bearings inside the first balance ring 2 and the second balance ring 5. The anti-collision airbag 4 is fixed outside the first balance ring 2 in an annular structure.

[0027] The third balance ring 6 is arranged inside the second balance ring 5, and second rotating shafts 8 are arranged between the left and right ends of the third balance ring 6 and the second balance ring 5. The third balance ring 6 is rotationally connected to the second balance ring 5 through the second rotating shafts 8.

[0028] In this embodiment, in combination with Figure 3 and Figure 4 as shown, the transport box 3 includes a box body 301 with an open upper end and a box cover 302 detachably arranged at the upper end of the box body 301. A notch for installing the box cover 302 is opened on the outer side of the upper end of the box body 301. A sealing strip 10 is fixedly embedded on the vertical wall of the notch, and the sealing strip 10 protrudes from the vertical wall of the notch. The box cover 302 is covered outside the notch to squeeze the sealing strip 10, thereby effectively preventing the explosive package inside the transport box 3 from getting damp. When the box cover 302 is covered outside the notch, the outer side wall of the box cover 302 is flush with the outer side wall of the box body 301, and a box buckle is arranged between the outer side wall of the box cover 302 and the outer side wall of the box body 301 to connect the box cover 302 and the box body 301.

[0030] Preferably, in this embodiment, anti-tipping plates 13 are arranged on the left and right sides of the bottom surface of the floating ship base 1. The anti-tipping plates 13 are perpendicular to the bottom surface of the floating ship base 1 and have an inverted triangular cross-sectional structure to prevent the floating ship base 1 from tipping due to side waves hitting it.

[0031] The working principle of the transport device for hydraulic tunnel blasting in this embodiment is:

[0032] By setting the floating ship base 1, the balancing mechanism, the transport box 3 and the anti-collision airbag 4, the floating ship base 1 has better stability compared to a simple floating board. During water transportation, the anti-tipping effect is better. The balancing mechanism can ensure that the transport box 3 remains in a balanced state during transportation. The explosive package is placed in the transport box 3 for transportation, effectively preventing the explosive package from getting damp and falling. By setting the anti-collision airbag 4, it can produce a buffering effect when a collision occurs during transportation.
