Description

Auto-driving fish way

The present invention relates to a self-propelled fishery system for aiding spawning of regressive fish, and more particularly, in the case where a fishery is to be installed at a later time in a dam where no fishery is installed, or when a fishery is simultaneously installed in a newly installed dam. It is directed to a self-propelled fish system that allows fish downstream of the dam to safely and efficiently move upstream of the dam.

In conventional reservoirs or dams, when the fish is not installed or installed, it is installed at a slope similar to that of the embankment, such as a cascade of fish. Inevitably, there was a problem in that the efficiency as well as cost a lot of construction costs.

In addition, if you want to install an elevator or a lift on existing dams or reservoirs that do not have an island installed, the fish will be installed in the air, thus harming the natural landscape and worsening the structural safety of the dam or reservoir. If you try to install the reservoir or dam aside, the moving distance is long, and the construction cost increases.

In addition, as the inclined structure installed on the upstream slope, water and fish are simultaneously dropped and flowed together with the reservoir water which is pumped up using a water pump, so that the fish are not only impacted, but also flow with the surface of the inclined structure heated or cooled at high or low temperatures. There is a disadvantage that the fish is stressed due to the temperature difference of the water, and also the problem that the chute early aging due to the blue waves generated on the dam or reservoir surface.

Therefore, the present invention was created to solve the above problems, the object of which is to install the fish after the dam in the dam is not installed or to install the fish at the same time to install a new dam at the same time Provided is a self-propelled fish system that allows fish downstream of the dam to safely and efficiently move upstream of the dam.

In order to achieve the above object, the present invention, the fish catching station is built in a water channel for flowing the surface water of the dam or reservoir downstream;

It is configured to include a fish for transporting charity 30 to be discharged.

In addition, the construction of the fish catching station (A) is provided with a detection sensor (A-1) for detecting when the fish transport ship 30 reaches the standby position, while catching fish described later on one or both sides of the construction An air cylinder A-2 for operating the door opening and closing means 34 to open and close the fish catching door 35 of the barrel 37 is installed.

On the other hand, the position of the first bus station (B) to be built on the outer slope of the dam or reservoir may be installed at any position having a suitable distance from the fish catching station (A), but located on the inner slope of the dam or reservoir Since the second bus station (C) becomes a storage location changes every day, it is necessary to set the construction location in consideration of the maximum storage amount. The reason for this is to prevent the electric shock accident or short (short) phenomenon occurs when the power line supplied to the traction bus 20 is stored in water.

In addition, the charity track rail 10b installed from the second bus station C to the surface water of the dam or the reservoir should be designed in consideration of the lowest reservoir position as opposed to the above. The reason is to allow the catched fish to be discharged smoothly upstream of the dam or reservoir.

The chain drive system 27 includes a drive sprocket 27a installed on the output shaft of the charity towing motor 25, and a driven sprocket 27b installed on the central shaft of the bobbin 26 and the sprockets 27a and 27b. It is composed of a chain 27c for connecting and coupling.

In addition, the lower portion of the support frame 21 is provided with a track guide means 28 for maintaining the track. The track guide means 28 is a guide rail 28a which is installed on the sleepers 13 between the gear rails 12 and the guide roller 28b which is coupled to the guide rail 28a to guide the linear movement. It is configured to include.

In addition, on the upper portion of the support frame 21 is provided with a riding rail 29 for allowing the fish-carrying ship 30 to ride by having the same phase difference as that of the track rails 10a and 10b.

On the other hand, on the sleeper 13 under the support frame 21, a power cable 14 for supplying power to the bus towing motor 22 and the charity towing motor 25 surrounds the non-conductive sheath rail 15. Installed in a stacked form, the support frame 21 side is provided with a brush (21a) is always in contact with the power cable 14 is installed.

Next, a specific embodiment of the fish transport charity 30 will be described.

A triangular support frame 32 is formed that includes a horizontal frame 32a opposed to the base frame 31 and installed therebetween.

In addition, a styrofoam buoy 33 is mounted on the base frame 31 and the extension plate 31a which is extended to have a predetermined inclination on the rear side of the base frame 31 to generate buoyancy.

In addition, it is installed by the hanger bracket (32b) to maintain the absolute horizontal on the horizontal frame (32a) of the support frame 32, the fish catching door freely opened and closed by the door opening and closing means 34 on one side ( 35 is provided, and a fish trap (37) having a fish release door 36 to be opened and closed by the buoyancy of the buoy 33 and the wire 33a in the lower portion 33.

Here, in a specific embodiment of the door opening and closing means 34, at the side of the fish catching cylinder 37, the spring spring 34a and the spring spring 34a having an elastic return force at all times to apply an elastic force The belt 34b coupled to the rotating spring 34a so as to apply rotational force, and the wire 34c connecting the end of the mainspring 34a and the fish catching door 35 to the belt 34b. Protrudingly installed at an arbitrary position, the fish feed line 30 is composed of an opening / closing section 34d which interferes to move the belt 34b by the operation of the air cylinder A-2 at the standby position of the fish catching station A. do.

The installation direction of the air cylinder (A-2) may be a vertical direction on the fish catching station (A) structure, as shown, may be a horizontal direction. However, when the air cylinder A-2 is horizontal, the positions of the belt 34b and the opening / closing 34d of the door opening / closing means 34 should be corrected in order for the operating force of the cylinder to reach the opening / closing 34d.

In addition, the wire 33a connected between the mouthpiece 33 and the fish release door 36 spans a plurality of pulleys to maintain tension and at the same time spans the support frame 32 and the horizontal frame 32a and into the barrel. It extends and is connected to the fish release door 36. The weight 33b may be additionally configured on the wire 33a in consideration of the buoyancy or the weight of the buoy 33.

On the other hand, the configuration of another embodiment that can open and close the fish release door 36 is as shown in FIG.

That is, the bracket frame 60 is installed on the upper portion of the fish trap cylinder 37 so as not to interfere with the horizontal frame 32a of the support frame 32, and the motor 61 and the motor on the bracket frame 60 are mounted. Coupling roller 62 and the storage battery 63 for supplying power to the motor 61 and the winding roller 62 to rotate and coupled to the shaft and the wire (33a) connected to the fish discharge door (36) 33) may be used to replace the way to open and close the fish release door (36).

Although not shown in the figure, it can be applied as a means for opening and closing the fish catching door 35 using the same apparatus as described above. Of course, in this case it will be obvious that the configuration of the above-described door opening and closing means 34 and the air cylinder (A-1) installed on the construction of the fish catching station (A) to operate the same.

Subsequently, under the base frame 31, guide rollers 38 which are guided to the track rails 10a and 10b for sliding and slide are formed.

In addition, when the fish transporting charity (30) is moving to the standby state of the fish catching station (A) on the charity track rail (10a), the current flows downstream and buoyancy of the fish catching barrel (37) itself for instant fish transport The own ship 30 may be separated from the own ship track rail 10a. To prevent this, a departure prevention guide 31b is formed at the bottom of the base frame 31 adjacent to the guide roller 38. Specifically, the departure prevention guide 31b is installed at one end of the charity side and the other side is hung by the rail side to prevent the guide roller 38 from being separated from the track rail 10a.

In addition, in the horizontal frame (32a) of the support frame 32, a horizontal holding rod (39) provided with a horizontal adjusting weight (39a) is integral with the hanger bracket (32b) to adjust the absolute horizontality of the fish catching cylinder (37). It can be configured as. At the tip of the horizontal holding rod 37, a detection dog 39b is placed in contact with the detection sensor A-2 when the fish transporting vessel 30 reaches the standby position of the fish catching station A.

Meanwhile, on the base frame 31 proximate to the fish catching vessel 37, a cylinder fixing means for controlling the movement of the fish catching vessel 37 when the fish catching vessel 30 moves to the fish catching station A ( 40) may be further configured. The reason is that the horizontal frame 32a of the support frame 32 when the fish transport ship 30 is unloaded from the tow bus 20 stopped at the first bus station B to reach the standby position of the fish catching station A. When the fish trap (37) is installed on the rotating material is empty, it is impossible to maintain the absolute horizontal state by buoyancy while entering the water flowing downstream, the detection dog (39b) and the sensor (A- 2) may not match, because the fish catching cylinder 37 is rotated, the air cylinder (A-2) can not operate the door opening and closing means 34 properly. Therefore, the barrel holding means 40 is to maintain the absolute horizontal level of the fish catching barrel 37 before arriving at the fish catching station (A).

Specific configuration of the tube holding means 40 according to the above, the friction fixing plate 41 which is supported by the spring 42 on the base frame 31 and surface-compression fixed to the fish trap cylinder 37, and the base Slidingly coupled to the casing 43 of the lower frame 31, the locking lever 44a is laid on one side and connected by the friction fixing plate 41 and the wire 44b, the lock groove 44c is formed at the bottom A moving pin 44 and a lock pin 45 that is coalesced by a spring 45a on a casing 43 below the moving rod 44 and selectively fits into a lock groove 44c of the moving rod 44; And a release lever 46 coupled to the pull string 46a at the end of the lock pin 45 and hinged to the casing 43, while the first bus station B and the fish catching station ( A) mechanically actuating the barrel fixing means 40 on the sleepers 13 for holding and supporting the charity rail 10a therebetween; The release / lock means 50 may be configured.

Accordingly, the release / lock means 50 may include a release lever interfering plate 51 which interferes only with the release lever 46 when the fish catching vessel 30 moves to the fish catching station A, and the own vessel The catching lever interfering plate 52 which interferes only with the catching lever 44a when moving from the fish catching station A to the first bus bar station B has a predetermined phase difference from the release lever interfering plate 51. On the sleeper 13 is installed to be rotatable by the hinge shaft 54. The locking lever interference stand 52 is a combination of the two members by the installation of the spring hinge 53 with a built-in torsion spring, the spring hinge 53 is installed in one direction in which the locking lever 44a interferes do.

In addition, the release / locking means 50 is installed between the lower portion and the sleeper 13 and includes a separate spring 55 having a constant magnification of the spring 42 elastic modulus of the barrel fixing means (40).

The operation of the present invention configured as described above will be described.

The description of the operation of the present invention will be described from the process in which the tow bus 20 stopped at the first bus station B moves the fish transport ship 30 to the standby position of the fish catch station A. FIG.

The towing bus 20 that has arrived at the first bus station B is driven by the own towing motor 25 in a predetermined order. The driving force of the charity towing motor 25 transmits a rotational force to the bobbin 26 through a chain drive system 27 which is a combination of the sprockets 27a, 27b and the chain 27c, and on the bobbin 26. As the wound traction rope 26a is released, the fish-feeding ship 30, which is relied on, moves to the fish catching station A via the charity track rail 10a.

As shown in Figure 8 to 10 during the movement, the container holding means 40 formed in the lower support frame 32 of the fish transfer charity 30 is released / locked in the interference position on the sleeper 13 Operation is effected by means 50.

Specifically, the release lever 46 connected by the lock pin 45 and the pull string 46a, and the latching lever 44a protruding from the side of the movable rod 44, have a fish transfer line 30 for catching the fish. While moving to the standby position of A) is placed in the interference position of the release lever interferer 51 and the latch lever interferer 52 of the release / locking means 50, the locking lever interferer 52 has two members The upper member is combined by the installation of the spring hinge 53 and the upper member is rotated about the direction of travel to the fish catching station A, so that it is passed without substantially interfering with the locking lever 44a, while The release lever 46 positioned at is in the interference range of the release lever interferer 51 to rotate the release lever 46 counterclockwise about the hinge.

The lock pin 45 connected by the release lever 46 and the pull string 46a is moved downward while winning the elastic force of the spring 45a, and at the same time, the lock pin 45 is separated from the locking range of the locking groove 44c of the movable rod 44. .

At this time, the movable rod 44 connected by the friction fixing plate 41 and the wire 44b has its friction fixing plate 41 by the elastic return force of the spring 42 holding the friction fixing plate 41 as the locked state is released. Push upwards to fix the fish catch barrel 37 in the free rotation state to an absolute horizontal state.

Thereafter, when the fish feed line 30 reaches the standby position of the fish catching station A completely as shown in FIG. 3, the detection dog 39b at the tip of the horizontal holding rod 39 is located at the opposite position. A-1) is touched, and the power of the charity towing motor 25 that drives the signal bobbin 26 is cut off.

When the air cylinder A-2 located at the side of the fish catching station A is operated by the sensing operation as described above, the belt 34b is pushed vertically downward between the opening and closing sections 34d of the door opening and closing means 34. ) By applying an elastic force to the mainspring (34a) by the interlocking of the ()) to release the wire (34c) wound on the mainspring (34a) to open the fish catching door 35 in front of the fish catching cylinder (37).

At this time, the water flowing through the fish trap cylinder 37 is flowed back so that the regressive fish flows into the fish trap cylinder 37 and is filled to return the air cylinder A-2. The wire 34c is rewound by the elastic return force to close the fish catching door 35.

Thereafter, the charity towing motor 22 of the traction bus 20 is reversely driven, thereby rewinding the traction rope 26a to pull up the fish transporting charity 30 toward the traction bus 20. Before riding on the traction bus 20, the barrel fixing means 40 of the fish catching charity 30 is subjected to the interference of the release / lock means 50 again, specifically, already rotated counterclockwise to release the lever. The release lever 46 in a state out of the interference range of the interference stand 51 passes as it is, but the locking lever 44a is caught by the locking lever interferer 52.

At this time, the release / locking means 50 has a structure rotatable by the hinge shaft 54 on the sleeper 13, but the elastic modulus of the spring 55 which is installed in the lower portion thereof holds the friction fixing plate 41. Since the spring 42 has a constant magnification of the elastic modulus, the locking lever interfering plate 52 which interferes with the locking lever 44a pulls the movable rod 44 while overcoming the spring 42 of the friction fixing plate 41. The wire 44b is drawn by the elastic return force of the spring 45a to the lock groove 44c of the movable rod 44 while the position fixing state of the fish catching cylinder 37 is released while pulling the friction fixing plate 41. The lock pin 45 is fitted to completely release the friction fixing plate 37.

At this time, the locking lever 44a is out of the interference range of the locking lever interference stand 52 while overcoming the spring 55 of the release / lock means 50 because the position movement is impossible.

The continuously moving fish feed ship 30 is riding on the riding rail 29 of the traction bus 20, the power is cut off the charity towing motor 25.

After that, the bus towing motor 22 is driven and its driving force is driven through the chain drive system 24 in which the sprockets 24a, 24b and the chain 24c are combined. The uphill inclination is increased by rotating the driving roller 23 engaged with the gear. At this time, the guide roller 28b of the track guide means 28 is guided by the guide rail 28a so that there is no fear of being derailed from left and right.

In addition, since the traction bus 20 is a moving body, it may be restricted to supply power to each motor on the bus. According to the present invention, the power cable 14 is installed inside the covered rail 15, which is the same insulator as the track rail, and the brush 21a is installed in the power cable 14 so that the contact state is always made while sliding. Therefore, the problem of power supply can be solved.

On the other hand, while the tow bus 20 passes the uphill slope and the top slope of the dam or the reservoir, the position of the tow bus 20 and the fish transport vessel 30 riding therein is reversed, but the fish catch barrel ( 37) does not worry that the contents of the inside of the barrel will be spilled because it always maintains the absolute horizontal, when the tow bus 20 arrives at the second bus station (C) power of the bus towing motor 22 is At the same time, power is applied to the charity towing motor 25 to release the towing rope 26a wound on the bobbin 26, and the fish transporting charity 30 is stored on the charity track rail 10b by the load. Will move towards the surface.

When the fish feeding charity 30 moves into the surface water of the dam or the reservoir, buoyancy force acts on the styrofoam buoy 33 located on the extension plate 31a extending to the base frame 31. Silver pulls open the fish release door 36 under the fish catching vessel 37 connected by the wire 33a to release the trapped regressive fish into the dam or reservoir.

On the other hand, in another embodiment that does not use the buoyancy of the buoy 33, the opening and closing means of the fish release door configured on the bracket frame 60 on the upper portion of the fish trap (37), that is, the power from the battery 63 The winding roller 62 is rotated forward / reversely by the rotational force of the motor 61 which is supplied with the rotational force to generate the rotational power, and the wire 33a wound around the winding roller 62 is unwound or wound to release the fish release door ( 36) can be opened and closed.

Thereafter, when the fish-carrying vessel 30 is pulled back to the traction bus 20 stopped at the second bus station C, the float 33 gradually loses buoyancy and is connected to the wire 33a. The fish release door 36 is closed by the weight of the weight 33b and the fish release door 36. When the buoyancy is completely lost, the float 33 is naturally placed on the extension plate 31a.

Since the subsequent operating states are in the reverse order, detailed description is omitted.

The present invention described above is not limited to the above-described embodiments and drawings, and various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention. It will be apparent to those who have

By applying the present invention as described above, even fish with poor swimming ability can be safely and efficiently moved upstream of the reservoir or the dam, and in particular, it does not impair safety even in the existing dam or reservoir where no fish is installed. There is an advantage that can be easily installed in the range that does not greatly reduce the construction cost, and also when planning a new dam or reservoir, the present invention can be installed safely, efficiently and economically.

In addition, although the present invention has not been described in detail, the installation of a sensor for detecting an operation state at a predetermined position of each station, a traction bus and a fish catching ship, can operate with a minimum number of management personnel at a control station controlling the same. By using the microcomputer, it is possible to automatically control the position of the fish catching vessel for driving the traction bus, towing the fish catching charity, and to release the catched fish from the stage of catching the fish by the constant flow. Therefore, there is an advantage that can significantly reduce labor costs, including labor costs.
