Description

Automatic Start-Controlling Machine for Racing of Boats}

The present invention relates to an automatic starting device for water sports, and more specifically, to the operation of the game fairly by equalizing the starting line and the starting time of each lane without the help of the operating personnel during the water game, such as canoe, rowing, chartering. The present invention relates to an automatic start device for a water game.

Canoeing, rowing or chartering is a speed competition that makes it very important for all participating canoes, rowing and chartering to start at the same time on the same starting line. However, since these competitions are held in rivers, lakes, dams, etc., there is a problem that the starting position for each lane is changed by wind or water flow.

In order to solve this problem, typically, the race management staff helps ships located in each lane behind the starting line to be located on the same starting line, or installs a fixed starting stage in the stadium. However, it is difficult to induce accurate simultaneous departures when a large number of personnel are involved when operating personnel are involved, and there is a disadvantage that excessive installation and maintenance costs occur when installing a fixed starting stage.

In order to solve this disadvantage, Japanese Patent Application Laid-Open No. 2005-177419 (Adjustment Competition Horn) raises the gate to the wire connected to the motor, and when the boat leaves, the gate is rotated and lowered by the operation of the remote control device. Disclosed is a starting stage for rowing races, which is configured to be started. However, according to the above technique, the gate is pulled by the wire to close the gate, and then the wire is released and the gate is rotated and lowered by gravity. Therefore, in the case of a plurality of starting stages, since the lengths of the wires are all different, it is difficult to simultaneously open the gate accurately at the entire starting stage. In addition, the boat is wrapped in all-left-right by the starting platform, which may cause the boat or the oars to hit the starting platform during the full power departure.

Korean Patent No. 733552 (Automatic starter for water games using pneumatic) includes a starting bar extending longitudinally in each lane of the lane and rotating to an extended lower end point and having a stop plate installed at an upper end opposite to the point; A pneumatic cylinder hinged to the lower end of the starting bar; Drive means for operating the pneumatic cylinder to rotate the starting bar; Disclosed is an automatic start apparatus for a water race, comprising a support truss mounted with a driving means and installed close to the center of the water in a lane (see FIGS. 1A and 1B). However, according to this technique, since the starting bar has a large rotation axis and a large area of the stop plate, a large capacity pneumatic cylinder is required due to the resistance of water during rotation and descent, and due to the rapid rotation and descent of the stop plate and the starting bar, Disturbance of the water stream occurs in front of the lagoon, affecting the boat's natural starting. In addition, since the starting bar and the stop plate are fixed lengths, it is impossible to adjust the height according to the depth of the stadium, and the complicated device configuration (pneumatic cylinder-hinge coupling part-starting bar-stop plate) can be used to rotate, lower, rotate, and raise the stop plate. consist of.

On the other hand, Korean Patent No. 859171 (automatic starting device for water racing) by the present inventors (A) underwater bridge that can equalize the starting line and the starting time while minimizing unnatural effects on boats and the like; (B) a pneumatic cylinder is installed on the underwater bridge to move up and down; (C) a holder installed at the end of the pneumatic cylinder rod; And (D) driving means for operating the pneumatic cylinder. The automatic starting device for a water game is disclosed (see FIGS. 2A and 2B). As a result, a holder (stop plate) is mounted at the end of the pneumatic cylinder rod installed vertically, so that the holder can be simply raised (Fig. 2a)-lowered (Fig. 2b) through the operation of the pneumatic cylinder. Therefore, it is possible to freely adjust the height of the simple structure, it was possible to automatically start the device for water games in which the disadvantages of the Korean Patent No. 733552 is eliminated.

However, as a result of repeatedly applying the automatic starting device for water sports according to the above-mentioned Korean Patent No. 733552 or 859171 to the field, a new problem was unexpectedly found. That is, in the case of these devices, it is often the case that the heavy boats aboard the boat impact the starting bar (heading 733552) or pneumatic cylinders (heading 859171) standing vertically during the boat's alignment process. Occurs. If the starting bar or the pneumatic cylinder rod were bent due to the impact, the device could not be operated or the starting position could be changed.

3A to 3C are perspective views and side views of the holder 30 in a raised state, an intermediate state, and a state in which the holder 30 is lowered in the automatic start device for water games according to the present invention. In the present invention, the structural relationship between the three-way pneumatic cylinder 20, the rotating frame 25 and the holder 30 and the underwater bridge 10, and its operation mechanism is characterized in other buoys, air tank 44 in Figures 3a to 3c. ), Control units and the like are omitted. That is, Figures 3a to 3c showing the automatic start device for a water game according to the present invention, for example, can be installed by replacing the part indicated by the red square in Figure 2a corresponding to the prior art. Therefore, in the following description, assuming that the structure shown in Figures 3a to 3c is replaced with a portion (pneumatic cylinder 20, holder 30 and part of the underwater bridge 10) indicated by a red square in Figure 2a Shall be.

3A to 3C, a portion of the underwater bridge 10 is illustrated in a plate shape for the sake of understanding. However, in the present invention, if the underwater bridge 10 functions as a support for supporting the pneumatic cylinder 20, the rotating frame 25 and the holder 30, etc., the specific shape or structure can be freely selected, whether plate or frame. It will be apparent to those skilled in the art.

Canoes, rowing or chartering arenas are usually set up outdoors such as lakes or rivers, each consisting of one or a plurality of lanes of predetermined width. A buoy is installed to mark the lane, which is fixed to a wire installed underwater.

The automatic starting device according to the present invention includes a pneumatic cylinder (20) for stretching and contracting, a rotating frame (25) connected to the pneumatic cylinder (20), a holder (30) installed at the vertex end of the rotating frame (25), It consists of a driving means 40 for operating the pneumatic cylinder 20, and the underwater bridge 10 to which they are mounted. At this time, the pneumatic cylinder 20 and the rotation frame 25 is rotatably coupled to the underwater bridge, and the pneumatic cylinder 20 and the rotation frame 25 is also rotatably coupled. In the drawings, the hinge coupling portion HC is illustrated as an example of the rotatable coupling.

In the present invention, the rotation frame 25 is A-shaped and consists of reinforcing bars 26 between both legs and legs. Both legs of the rotating frame 25 are rotatably connected to the underwater bridge 10, and the reinforcing rod 26 is rotatably coupled to the rod end of the pneumatic cylinder 20. The holder 30 is installed at the vertex end of the rotation frame 25.

On the other hand, the underwater bridge 10 may be maintained in a suspended state in the water, depending on the conditions of the stadium, may be seated on the bottom of the water. When seated on the water floor, level it in an appropriate way.

The automatic starting device according to the present invention is operated in the following manner.

First, the rotation frame 25 is erected so that the holder 30 reaches an appropriate height while the pneumatic cylinder 20 extends before the boat departure signal (FIG. 3A). In this state, the canoe adjustment charter's stent post or nose cone's top end abuts against the holder 30, and the canoe adjustment charter's rocking and traveling (starting) are prevented. When the starting signal is received, the pneumatic cylinder 20 quickly contracts and the rotation frame 25 is laid down momentarily, and the holder 30 mounted at the vertex end of the rotation frame 25 descends below the bottom surface of the boat ( Figure 3a-3b-3c). This makes it possible to proceed with the boat.

That is, in the automatic starting device according to the present invention, the pneumatic cylinder 20 is extended before the start signal, and ultimately the holder 30 at the end of the rotation frame 25 is kept on the water so that the boat cannot go forward. A, upon departure, the pneumatic cylinder 20 is contracted and ultimately the holder 30 descends into the water (below the bottom of the boat) to allow the boat to start. Thereafter, the pneumatic cylinder 20 is elongated again to return the holder 30 to the surface of water for the late game (Fig. 3C → Fig. 3B → Fig. 3A).

In the case of installing and operating a plurality of automatic starting devices, the contraction of the pneumatic cylinder 20 by the predetermined control box 48 having a circuit for transmitting electrical signals to the solenoid valves of each automatic starting device at the same time, thus ultimately the holder (30) is to be made at the same time.

In the present invention, the driving means 40 is for driving and controlling the pneumatic cylinder 20, and in the claims, the pneumatic cylinder 20, the driving means 40, a solenoid valve (not shown) are described separately. However, in the art, all of these are understood as a pneumatic cylinder 20 system. In the present invention, a conventional pneumatic cylinder 20 system can be used.

The pneumatic cylinder (20) system usually comprises: (1) an electric air compressor (42) and an air tank (44) for making compressed air; (2) an air supply unit consisting of an air filter, a valve, an air transfer pipe, a pressure gauge, and the like. Cylinder 20 ④ solenoid valve for changing the direction of air to drive the cylinder rod up and down and ⑤ control unit (control box 48) for controlling the operation of the air compressor 42 and the operation of the solenoid valve. .

In the present invention, the pneumatic cylinder 20 is preferably a double acting type that can adjust the maximum stroke so that the height of the holder 30 can be freely adjusted according to the conditions of the stadium. Since the structure and operation of the pneumatic cylinder 20 are widely known, the specific structure and operation of the pneumatic cylinder 20, such as electrical wiring for operating the solenoid valve, programmed PLC circuits, and operation by generating an electrical signal, are described. Illustration and description are omitted.

The air compressor 42 is connected to the air tank 44 installed on the ground or the water surface and installed in the water by an air transfer pipe (not shown), and functions to store compressed air. In the present invention, the auxiliary air tank 45 for assisting the air tank 44 may be provided. The auxiliary air tank 45 operates the pneumatic cylinder 20 more than a predetermined number of times even when the power is cut off by storing the compressed air in the air compressor 42 and supplying compressed air to the air tank 44 again. Make it possible.

On the other hand, the holder 30 is in contact with the stern post of the canoe, adjustment, and charter or the top end of the nose cone, so that the tip of the boat is not damaged by friction caused by the shanghaidong of the holder 30 It is preferable to mount several rollers (not shown). In addition, the holder 30 may be detachably coupled to the rotation frame 25 for the convenience of transportation and storage. Of course, the holder 30 can be applied by appropriately modified according to the size and shape of the boat.

The automatic starting device according to the present invention may be equipped with a wheel 14 for the convenience of movement. In addition, although not described separately, the automatic start device for a water game of the present invention, a plurality of buoys and a buoy that functions to display a plurality of lanes on the water surface for smooth running of a water game, such as ordinary canoe adjustment, fixed the buoys It may be used with wires and the like connected underwater.

Hereinafter will be described the operation of the automatic start device for a water game of the present invention configured as described above.

After the automatic starting device according to the present invention is installed in a place where water games such as canoeing, adjusting, and chartering are held, the air compressor 42 is operated to store a sufficient amount of air in the air tank 44 in advance. Before the start of the game, the pneumatic cylinder 20 is extended to raise the rotation frame 25 at a predetermined angle. As a result, the holder 30 installed at the vertex end of the rotation frame 25 is raised above the water surface so that the boat cannot move forward from the starting line (Fig. 3C → Fig. 3B → Fig. 3A). When the start button of the control box 48 is pressed at the same time as the start signal (the start signal and the button electrical signal of the control box 48 may be automatically generated at the same time), the electric signal generated by the control box 48 By the solenoid valve of the pneumatic cylinder (20) installed in each lane is operated at the same time. Accordingly, the compressed air of the air tank 44 contracts the pneumatic cylinder 20 so that the pivot frame 25 is laid at a predetermined angle so that the boat 30 can be started by descending below the surface of the boat 30. Figure 3a-3b-3c). After completion of the boat, when the original return electric signal from the control box 48 is transmitted to each solenoid valve automatically or manually, the compressed air of the air tank 44 expands and operates the pneumatic cylinder 20 so that the holder 30 It rises again to the surface (Fig. 3c → Fig. 3b → Fig. 3a).
