Detailed Description
Example 1: referring to fig. 1, a concrete structure of the present invention is shown, which is a fish blocking system for fish farming in a clean water area, according to the condition of the water area, and based on the principle of avoiding fish running, a fish blocking dam is disposed at the upstream and/or downstream of the water area, which traverses the cross section of the water area, so as to form a relatively closed fish farming water area capable of passing water but blocking fish.
In this example, the fish blocking dam body comprises four support piers 2, and in this example, the support piers 2 are of a steel fence structure. And better water passing capacity is formed.
The gate 1 is installed between the support piers 2, as shown in fig. 2, the steel fish blocking fence supported by the steel beams constitutes the gate 1, and the longitudinal fence 101 and the transverse fence 102 of the steel fish blocking fence are arranged in the front and back direction of the water flow, i.e. the longitudinal fence 101 is positioned at the front side of the upstream incoming water. The gap between the longitudinal fences 101 has a deep space in the direction of the water flow. The garbage in the space is not easy to enter, and water flows conveniently; the garbage is pushed by water along the surface of the longitudinal fence 101 to turn over the top end of the gate 1 to enter the downstream, and is not easy to be blocked by the transverse fence 102.
The width of the gate 1 corresponds to the width of the space between the support piers 2. The bottom end of the gate 1 is hinged to an installation bottom surface formed by the concrete foundation piles 7 through a rotating shaft 8, a steel cable of a crane 3 (a hoist, a winch and the like) is connected to a steel beam at the top end of the gate 1, the crane 3 drives the gate 1 to swing up and down around the rotating shaft 8 at the bottom end, and the swing angle is 0-45 degrees; two cranes 3 are mounted on working bridges 4 spanning the spacing of the individual piers 2.
When the gate swings to a high point position of 45 degrees, the gate is in a working state, the gate traverses between the two supporting piers 2 in an inclined posture, and the steel fish blocking fence on the inclined surface intercepts upstream fish and garbage (wave debris) coming from flood and cannot pass through. Garbage surges along the inclined surface to the top end of the gate along with water flow, the inclination of the gate can be freely finely adjusted, and manual intervention such as pushing and raking can be assisted, so that the garbage is discharged to the downstream from the top end of the gate turning over the inclined surface, the gate 1 is effectively prevented from being blocked by the garbage floating on the water and sinking in the water, and no resistance is caused to flood discharge; the intercepted fish is frightened and can swim back to the reservoir, the fish which does not swim back can be captured because of the influence of the flow rate of water, the adult fish is harvested, and the fry is sent back to the net cage of the reservoir for temporary stocking. The working bridge can also be used as a safety rope mounting base point for operators, so that the operators can conveniently stand on the gate to catch fish, push garbage to downstream and the like. The working bridge can be of a double-layer structure, the crane is arranged on the top layer, and the fish can be loaded and unloaded conveniently through the load-carrying truck on the bottom layer.
When flood running is possibly hindered, the gate can be swung to the low position of 0 degree (namely, the gate is horizontally arranged parallel to the installation bottom surface) by the crane, and normal flood overflowing can be realized. When the gate swings to 0 degree, the position of the gate is lower than the dead water level of the water area. To avoid any hindrance to the flood. If the river channel or canal is shallow, the fish blocking gate can be kept at the same level with the plane of the river bottom or the channel bottom surface after being laid flat for water passing or ship passing according to requirements. Under the condition that the spillway is arranged in the water area, the width and the depth between the support piers 2 are not less than the width and the depth of the spillway, so that the spillway is not influenced.
In this example, the gate 1 is partially arranged outside the support piers 2, and holes through which fish can pass are formed around the gate 1. For this purpose, the left, right and front sides of the gate 1 are provided with auxiliary fences 6 for plugging leaks, and the auxiliary fences 6 block fish and debris from entering, but water can pass through the auxiliary fences 6. The outer side of the auxiliary fence 6 is a slope surface conforming to the gate 1, and the included angle between the slope surface and the horizontal plane is preferably 45 degrees. The inner side of the auxiliary fence 6 is a vertical surface, so that the gate 1 can swing conveniently. The fish and the garbage are turned over to the upper surface of the gate 1 in the inclined posture of the auxiliary fence 6 along the slope surface at the outer side, and the gate 1 can work according to the flow.
The auxiliary fence 6 is preferably formed by steel fish blocking fences supported by steel beams, and the longitudinal fence and the transverse fence of the steel fish blocking fence are arranged in the front and back direction along the water flow direction.
The bottom surface of the subsidiary barrier 6 may be provided with a concrete support frame.
In this example, the installation bottom surface formed by the concrete foundation piles 7 is arranged below the gate 1, so that the hinge point installation base surface of the gate 1 and the dead water level of the water area are kept horizontal, the flood discharge pressure and the manufacturing cost of the gate are reduced, the gate is convenient to install, and the water flow of reservoir flood discharge can pass through the lower surface of the gate 1. And an auxiliary fence 6 for plugging a leak is arranged in front of the concrete foundation pile 7 and below the gate 1.
And under the condition that the construction surface meets the requirements, the concrete foundation pile 7 is not arranged.
In this example, the gate 1 is installed at a height corresponding to the normal water level of the water area. However, in order to avoid fish leakage caused by overflow of flood water in flood season, in other embodiments, an auxiliary gate may be arranged behind the gate 1, and the installation height of the auxiliary gate is set corresponding to the flood level of the water area. The structure of the fish blocking device is the same as that of the gate 1, the auxiliary gate swings to a low position of 0 degree for standby in usual time, and swings to a high position for blocking fish in flood season.
Example 2: referring to fig. 3, the difference from embodiment 1 is that in rivers, canals, channels, city protection rivers, large water diversion engineering channels or other water areas with narrow water channels, a fish blocking dam body crossing the cross section 202 of the water area can be built only by two support piers 201, and a gate 203 is arranged between the two support piers 201, so that the two support piers 201 are arranged on two sides of the water channel in order to avoid affecting water passing. The support pier 201 is of a steel fence structure to form good water passing capacity. The upstream face of the support pier 201 can also be set to a sloping surface to avoid blockage by accumulation of debris.
Example 3: referring to fig. 4, the difference from embodiment 1 is that a fish blocking dam 302 is constructed in the water area upstream of the spillway 301 of the reservoir dam 304, because the water is deep in front of the water inlet of the spillway 301. The fish blocking dam 302 is arranged on a foundation platform 303. The foundation platform 303 extends from the position of the fish blocking dam 302 to the spillway 301, and the foundation platform 303 is connected with the spillway 301. The height of the base platform 303 is not higher than the dead water level of the spillway 301. The main body of the foundation platform 303 is made of reinforced concrete or steel beam structure, and is provided with a steel fish blocking fence for blocking fish and wave debris from entering, but water can pass through. The foundation platform 303 is supported by columns, which are of reinforced concrete or steel beam construction.
The foundation platform and the fish blocking dam body thereof built in the water areas upstream of the spillways of the reservoirs, lakes and canal dams do not have any influence on the spillways and the safety of the dams.
Example 4: referring to fig. 5, the difference from embodiment 3 is that a scrap placing door 403 is arranged at a position of the base platform 401 near the water inlet of the spillway 402, and the scrap placing door 403 is connected with a scrap placing crane 404.
As the foundation platform 401 and the fish blocking dam body traverse the cross section of the whole water area, garbage (wave debris) is concentrated under the foundation platform 401, when a lot of garbage is accumulated under the foundation platform 401, the downstream end of the debris placing door 403 is lifted by starting the debris placing crane 404, and the debris placing door 403 is opened for a short time to allow the garbage to flow out to the downstream. And then the debris release door 403 is closed again. The chip discharging door 403 may not be put down due to a large water pressure, and the traction direction of the crane cable can be changed by the guide pulley arranged below the chip discharging door 403, so that the chip discharging door is pulled downwards to be closed.
Example 5: referring to fig. 6, the difference from embodiment 2 is that in a river, a canal, a berm river, a large-scale water transfer engineering canal or other water areas with narrow water passages, such as a large-scale water transfer engineering canal of north-south water transfer, a wide gate 501 is arranged between two support piers 502 to construct a fish blocking dam body traversing the cross section of the water area, and in order to avoid affecting water transfer, slopes 503 (shown by dotted lines) on both sides of the canal are excavated to cut slopes, and two support piers 502 are constructed.
The scheme has low installation investment cost and no influence, and silver carps and bighead carps in a certain proportion are scientifically released by using the water channel. The fish can be used as a sentinel for biologically detecting water quality, the water quality is improved, economic benefits can be generated, and the fish taste of the running water culture of the water channel is more delicious.
Example 6: referring to fig. 7, in a water area (such as a reservoir, lake, canal, etc.) having both a spillway 604 and a lock 605, the spillway water area and the lock water area are separated by a lock wall and a ship guide wall 606. Because the ship lock 605 can not run fish, the fish blocking dam 603 which traverses the cross section of the water area only blocks the cross section of the spillway water area and does not block the cross section of the ship lock water area, so as to avoid influencing navigation. In this type of water area, the ship lock 605 is located on the bank side of the water area (e.g., river), which is called the ship lock bank 602; the other bank of the water is referred to as the non-lock bank 601. Thus, in a body of water having both a spillway 604 and a lock 605, the fish dam 603 traverses the cross-section of the spillway body of water upstream of the spillway between the lock and/or lead walls 606 and the non-lock side banks 601.
Example 7: referring to fig. 8, when a fish blocking dam 701 is constructed in a river, a canal, or a lake where a ship lock is not installed, influence on navigation due to construction of the fish blocking dam 701 is avoided. Ship lock walls and ship guide walls 703 are built on both sides of the fish blocking dam body 701, and a left ship lock 704 and a right ship lock 702 are built between the ship lock walls and the ship guide walls 703 and a river bank 705.
A ship lock is built on one side of a river or a river, or a ship lock (ship passing channel) is respectively built on the left side and the right side of the river or the river, a ship can separately navigate along the water and against the water, the water flow speed is not fast at ordinary times, the gates above and below the ship lock are opened, and the ship can walk through the channel of the ship lock to navigate without influencing the navigation speed.
The navigation fish blocking method for the ship lock passageway comprises the following steps: the fish can be blocked by using the well-known low-voltage variable-frequency fish blocking method because the water flow in the water area is slow, the water channel is narrow and the corridor is long by using a channel in front of a ship lock and a ship lock corridor.
If the navigation of the ship lock passageway is in case of no blocking, the ship lock can be utilized to normally pass through the ship to block fish, the lower part of the ship lock is closed, a descending ship enters the ship lock, and then the upper ship lock is closed, because no water level difference exists between the upper part and the lower part of the ship lock, the lower ship lock is opened, and the ship enters the ship lock after exiting the ship lock. Thus, the lock passage can block the fish without flow speed at all. When flood rises, under the condition that fish cannot be blocked by a ship lock passageway at low voltage, a ship lock is adopted to pass through a ship, the operation is carried out according to the flow of the conventional common ship lock, the ship lock above the ship passing passageway is closed, the ship lock below the ship lock is closed after an ascending ship enters the ship lock, so that water level difference exists above and below the ship lock, then a culvert above the ship lock is opened to drain the water into the ship lock, the water level in the ship lock is leveled to the upstream water level of the ship lock, then the ship lock above is opened, and the ship which ascends goes out of the ship lock is descended to the ship lock. The fish blocking system is built in the water area, ship passing through the ship lock and ship passing through the ship lock channel are used for navigation, and the problem that the fish blocking system built in the water area cannot block fish when passing through the ship is solved. The fish blocking gate is also installed in the ship passing channel, when the ship with the extra-large flood cannot navigate, the upper part and the lower part of the gate of the ship lock are opened, the fish blocking gate installed in the ship passing channel is used for lifting and blocking fishes so as to prevent the ship lock from influencing flood overflow, and the fish blocking gate is flatly placed when the ship normally passes, so that the ship navigation is not influenced. Therefore, a fish blocking system can be built in a water area with busy ship transportation, such as a Dongting lake, for fish culture, and the water quality is improved.
In order to save cost, the fish blocking system can be built when the bridge is built in the water area. The fish blocking fence in front of the pier is supported by a steel beam frame or a reinforced concrete beam frame.
The foregoing embodiments are merely for clarity of explanation, and are not to be construed as limiting the present invention. The utility model discloses have known multiple substitution or warp in this technical field, do not deviating from the utility model discloses under the prerequisite of essence meaning, all fall into the utility model discloses a protection scope.
