DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a racing boat pit, and more particularly to an improvement of a racing boat pit conventionally provided in a racetrack.

[0002]

2. Description of the Related Art In a boat racetrack, a racing boat is moored in a pit provided in parallel at a required position on the quay side water surface,
Each raceboat races with an engine in each pit to perform maintenance, inspections, engine tests for each raceboat, or to go to a test run or start zone. (1) As shown in FIGS. 7 and 8, a known racing boat pit has a substantially rectangular hollow portion protruding slightly forward from a front wall, and a side extending forward from one end of the front wall. And a plurality of substantially L-shaped hull units or substantially circular L-shaped hull units having a deck and having a required number of bulk heads formed therein are connected in parallel.

(2) In a conventional pit, as shown in FIGS. 7 to 10, a tunnel-like water channel P having a wall provided at a lower portion of the pit main body is formed. Was changed downward to suppress the water flow.

(3) In a racing boat pit, a boat racer uses a propeller provided on a drive shaft of an engine of a racing boat on which he / she rides according to the water surface (seawater or fresh water) of a required boat racetrack. It is necessary to replace or check and replace the engine and the propeller.

(4) Further, in the known pits for racing boats, since the launching machine is located under the front lid of the bit, the fixing bolt is first removed, and then the front lid is also removed. , The maintenance work of the boat launcher is being carried out.

[0006]

As described above, the known pits for racing boats have the following disadvantages. (1) As described above, therefore, when each of the substantially L-shaped hull units is installed at a required location in the boat racetrack while towing the water surface,
Since the buoyancy of the substantially L-shaped hull unit or the substantially inverted L-shaped hull unit is not stable, the operator has a feeling of anxiety during the assembly work.

(2) As a result, the shape of the water flow passage and the exhaust gas duct was not appropriate, resulting in considerable resistance to the water flow. The pit resonates due to the passage of the water flow, causing abnormal rotation of the engine of the racing boat, and when the racing boat is returned to the water surface again, an excessive load is applied to the engine, and in the worst case, the drive shaft of the engine is broken. In some cases, the propeller was deformed.

(3) The maintenance work of the boat launcher is
Inspection, installation, repair, replacement work, etc. at the water site were quite difficult.

[0024]

【The invention's effect】

(1) As described above, the center line of the elongated auxiliary deck 22 in the longitudinal direction coincides with the center line of the substantially square main deck 14, and these members are symmetrical with respect to the center line in the longitudinal direction to stabilize buoyancy. Therefore, when these members are installed at required places in the boat racetrack while towing the surface of the water, the buoyancy is stabilized, and the worker does not feel uneasy during the assembling work, and the work becomes extremely easy.

(2) The center decks 32 are respectively arranged between the adjacent substantially square main decks 14,
Since it is fixed, the water flow generated by the rotation of the propeller flows straight through the continuous tunnel-shaped space formed in the water and in the air behind the engine of the race boat B, so that the resistance and resonance to the pit 10 for the race boat are reduced. Eliminate, reduce the burden on the engine, and after checking the engine,
Even if the racing boat is returned to the surface of the water again, the water flow smoothly passes rearward through the lower portion of the center deck 32, so that the excessive load of abnormal rotation of the engine is also eliminated, and the drive shaft of the engine is broken or damaged. There is no deformation of the propeller.

(3) Further, the maintenance hatch 36 hinged on the front end of the center deck 32 so as to cover the boat holder 38 and the like from above is lifted up. Maintenance work and inspection work of the boat 38 and the boat launcher are also facilitated.

(4) In addition, as described in claim 3, the interval between the pits 10 for the race boats arranged side by side can be adjusted according to the width of the race boat B to be stored. .
