Description

Water storage and slag removal system for river ecological fish culture and use method of the same

Technical field

The invention relates to the technical field of agricultural production fish culture, in particular to a water storage and slag removal system for river ecological fish culture and a method for using the same.

Background technique

As a kind of intensive agriculture, aquaculture, it refers to the cultivation of fish or various seafood in artificially opened fishing rods for consumption. According to different culture water quality, it can be divided into three categories: freshwater aquaculture, saltwater aquaculture and sea surface culture. It is the most densely distributed in the southwest coast, and the output value is the second largest in the offshore fishery. Under the influence of the rapid development of modern industrialization, ecological damage cannot be avoided, and many rivers, ditches and other flowing areas have been polluted to varying degrees. In addition to overfishing, the use of irrational fishing methods such as electric catching, mine catching, and drug fishing has led to a sharp decline in the abundance of wild fish resources in the above-mentioned flowing water areas.

It is known that people eat food in the waters of good fluidity. Compared with fish raised in ponds, lakes and cages, they generally have more delicious meat. In the existing rivers where river water flow is relatively stable, river cage intensive fish culture has emerged. At the same time, large-scale fishery farming has been carried out in the vicinity of rivers through the introduction of river water by cofferdams. When it comes to river water, it has more abundant water resources than traditional fish farming, which can improve the quality of fishery products to a certain extent. However, the water flow intensity of fish living areas in the above culture process is also relatively flat or static, resulting in the above culture. The swimming behavior of fish in the process is still not as good as that of natural fish growing in rivers in the natural environment, and it is not easy to obtain high quality freshwater fish products.

Summary of the invention

In view of the above-mentioned prior art, abundant river water resources have been used as freshwater fish culture water resources. Although the water resources are more abundant than traditional fish farming, the quality of fishery products can be improved to some extent, but the above The water flow intensity in the living area of the fish during the breeding process is also relatively flat or static, resulting in the swimming behavior of the fish in the above culture process is still not as natural as the natural environment in the river. The problem of the fish is not easy to obtain high quality freshwater fish products. The present invention provides a water storage and slag removal system for river ecological fish culture and a method of using the same.

In view of the above problems, the water storage and slag removal system for river ecological fish culture provided by the present invention and the use method of the system achieve the purpose through the following technical points: the water storage and slag removal system for river ecological fish culture, including parallel to each other And a plurality of side piers arranged on the same row, the adjacent side piers are provided with a ram, and the adjacent side piers are provided with a water filtering and slag removing portion;

The water filtering slag removing portion comprises a conveyor belt and at least two rollers for tensioning the conveyor belt, the rollers are located at different heights and the projections of the respective rollers toward the ground are not laminated, and the width direction and phase of the conveyor belt are The spacing direction of the adjacent side piers is common, and the conveyor belt is further provided with a gap for the passage of water flow, and at least one of the rollers is connected with a driving portion for rotating the brake roller;

A lifting mechanism for adjusting the position of the shutter in the height direction is also provided on each of the shutters.

In the prior art, freshwater fish farming cannot be directly used in river sections or ditches of rivers or ditches, because the water level of the river section or the ditch section is not easy to control first, especially in the dry season, and the river section and the ditch section may even be broken. At the same time, because the water in the river or ditches is flowing, there are often domestic garbage from the upstream, vegetation residues in the natural environment or animal carcasses in the rivers or ditches. In this way, if the scheme of damming and arranging water is used alone, the problem of preventing fish from escaping and removing debris suspended or floating in the aquaculture area cannot be solved, and the accumulation of the above debris will have a major impact on the quality of the water, even Lead to a large area of fish death.

In the water storage and slag removal system provided above, a plurality of side piers are arranged in the river channel or the ditch section, that is, the spacing direction of the adjacent side piers is parallel to the width direction of the river channel or the ditch section, and the side piers serve as the gate and the drainage water. In addition to the installation foundation and fixing and operation platform of the slag part, by controlling the height of each ram, the water level in the culture area can be separated from the water in the water body through the water removal and slag removal.

In the above-mentioned drainage water removing and slag removing section, the roller provided is equivalent to the belt axis as the conveyor belt, and the relative position of the roller is limited, and is used to obtain the following conveyor belt mounting form: the working surface of the conveyor belt is a sloped surface, and the working surface The lower end enters the water body, and the upper end of the conveyor belt is exposed to the water surface or even above the top end of the side pier. Thus, the device is used in the form that the working surface of the conveyor belt faces the upstream of the water flow, and the conveyor belt rotates. The driving direction of the conveyor belt is from the lower side to the upper side. Thus, when the system is in operation, the water body passes through the conveyor belt, and the debris or fish in the water body is blocked by the conveyor belt, and the fish is in the biological Escape from the conveyor belt, is confined within the culture area, and the debris is separated from the water body under the action of the conveyor belt, so as to achieve the purpose of removing impurities in the water body and avoiding the enrichment of debris in the culture area, ie The structure provided by the invention can effectively separate the impurities in the water body from the water body without affecting the normal flow of the water in the river or the ditch, and ensure the daily activity of the fish, thereby preventing water quality deterioration and disease retention, and at the same time facilitating prevention. Fish escapes to achieve the purpose of the fish ecological farming in rivers and ditches.

When the system is in operation, the device is arranged downstream of the culture area. If there is an individual in the fish population, the disease may be caused by the water flow, and the diseased fish may be automatically contacted by the water belt under the action of the water flow. Separated, in this way, the system is used for aquaculture of freshwater fish in aquatic water, and it also has a good effect of preventing cross-infection of fish diseases.

In the above structure, in order to avoid fish escape, the anti-escape net, the installation of physical barriers, the lower end of the conveyor belt on the river bed or the bottom of the ditch can be realized directly under the lower end of the conveyor belt to the bottom of the river bed or the ditch. .

In order to facilitate the collection and transfer of the above-mentioned debris which is finally dropped by the top end of the conveyor belt, a slag collecting station is arranged below the top end of the conveyor belt, and at the same time, the slag collecting table is placed in contact with the outer surface of the back surface of the conveyor belt or has a small gap. The scraping board removes the debris attached to the conveyor belt in time.

As a further technical solution for the above-mentioned water storage and slag removal system for river ecological fish farming:

As a specific implementation of the conveyor belt, the conveyor belt is composed of a plurality of mutually parallel tie bars and a plurality of mutually parallel partition plates, and the plurality of tie bars are sequentially connected in series to form a closed ring, and the adjacent tie bars are hinged. For the connection, the partition plates are fixed on the slats at intervals, and the longitudinal direction of the partition plates is located in the width direction of the conveyor belt, and the interval between adjacent partition plates is a gap for the passage of water. The above adjacent slats are hingedly connected so that adjacent ties can be relatively rotated to smoothly pass through the rollers, and the cavity structure formed between the inner side of the adjacent partitions and the ties is used for accommodating The area of the debris, or the surface of the conveyor belt and the surface of the debris, can generate a large static friction factor, so that the debris can be separated from the water body by the movement of the conveyor belt.

Especially in the flood season, the vegetation debris in the water body may be bulky, so that when the partition plate is in contact with the residual body, there is sufficient connection strength between the partition plate and the tie bar to realize the transport of the above debris. The conveyor belt has a plurality of said rings in the width direction, and each of the partition plates has a fixed connection point with each of the rings.

As a specific roller implementation, there are two rollers between adjacent side piers, and the two rollers are parallel to each other, one of which is disposed at the bottom of the side pier and the other roller is disposed at the side pier. Above, and the line connecting the two roller axes is at an angle of between 15° and 40°. In this solution, the angle between the line connecting the axis of the roller and the horizontal plane is defined to limit the inclination of the working face of the conveyor belt. If the above inclination is too small, it is necessary to set the working surface of the conveyor belt to be long to adapt. If the depth of the water changes, if the angle of inclination is large, this will cause the density of impurities to move with the conveyor belt, and it will not be separated from the water body. Therefore, the above angle is selected as the length of the conveyor belt to meet the water depth change, and most of the impurities A shorter conveyor belt length can be used with the conveyor belt.

The upper side of the step surface of the upper pier is preferably disposed upstream of the water flow to prevent the enrichment of the sediment, the fine stones, and the like at the lower roller from causing excessive resistance to the rotation of the conveyor belt.

Due to the action of water flow or debris, the working surface of the conveyor belt will inevitably bend toward the downstream side with a small curvature. The above bending is especially caused when the density of the debris is large or the local water body has a large flushing force. Obviously, the above bending causes the working surface of the sundries and the conveyor belt to be steeper, which is not conducive to the smooth movement of the debris with the conveyor belt. To avoid the above situation, each of the water filtering and slag removing portions is provided for a bending preventing portion of the bending deformation arc of the conveyor belt under the action of water flow or debris, the bending portion comprising a fixed substrate and a plurality of rollers or/and a plurality of rollers fixed on the fixed substrate, the roller or The axis of the roller is parallel to the width direction of the conveyor belt, the plurality of rollers or/and the plurality of rollers are distributed along the conveying direction of the conveyor belt, the plurality of rollers or/and the plurality of rollers and the working surface of the conveyor belt Inner surface contact.

A bottom side gasket is disposed under the shutter, and a projection of the free side of the shutter on the corresponding bottom side gasket is located between the left and right ends of the bottom side gasket.

The bottom bottom gasket is used for sealing the bottom of the ram and the river bed or the ditch. The upstream gasket provided above is used for sealing the end surface of the ram and the corresponding side pier, and the sealing ring is arranged at the upstream position of the gate groove. The upstream gasket can be brought into contact with the surface of the upstream side of the ram under the flushing of the water body, so that in the process of lifting and lowering the ram, the movement resistance of the ram can be prevented from being excessively caused by the sealing of the side seal of the ram, Both the bottom side gasket and the upstream gasket can be rubberized.

As a specific implementation form of the lifting mechanism, the lifting mechanism is one or more of a pneumatic transmission mechanism, a hydraulic transmission mechanism, a motor transmission mechanism, and an artificial lifting mechanism;

The pneumatic transmission mechanism is a pneumatic cylinder connected to the shutter;

The hydraulic transmission mechanism is a hydraulic cylinder connected to the brake plate;

The electric transmission mechanism includes a driving motor and a threaded rod connected to the rotor of the driving motor, and the threaded rod is screwed with the shutter;

The manual lifting mechanism is a chain hoist, a tooth meshing lifting mechanism or a thread lifting mechanism, and the thread lifting mechanism comprises a threaded rod and an internal threaded turntable threadedly connected with the threaded rod, the internal thread turntable being rotatable and opposite to the side pier The threaded rod is screwed to the shutter; the toothed engagement lifting mechanism includes a rack bar having a plurality of slots disposed evenly along the length of the length thereof, and a toothed disc engaged with the toothed teeth. The toothed disc is rotatable and fixed relative to the height of the side pier, and the lower end of the rack bar is fixedly connected with the shutter;

In the water body, the left and right side faces and the front and rear end faces of the ram may be in contact with the rough surface under the scouring force of the water body, in order to avoid or alleviate the above situation, it is advantageous to lift and lower the ram, the elevator The structure is also provided with a guiding mechanism for balancing the flow of water and the scouring force of the debris on the ram during the hoisting and lifting process.

Although the conveyor belt of the system provided above has the function of hydrophobic slag removal, its use will inevitably cause the flow resistance of the water in the section of the river channel or the ditches to become larger, in order to avoid the above-mentioned upper section of the river section or the ditch section caused by the water body resistance becoming larger. The water level rises, affecting the farmland, buildings, dams, etc. around the river. The water storage and slag removal system for river ecological fish farming is used in the widening section of the river. The above system is installed in the widened section of the river. By increasing the width of the river channel in the area where the system is located, the water level rise due to the factors of the system can be effectively avoided.

The invention also discloses another method for using a water storage and slag removal system for river ecological fish culture:

When the system is in operation, the device is installed downstream of the culture area, and if there is an individual in the fish group, the disease occurs. Therefore, due to the reduced stress, the diseased fish can be automatically separated from the conveyor belt when the water is in contact with the conveyor belt. Thus, the system is used for aquaculture of freshwater fish in aquaculture water, and it is also very good. The role of preventing cross-infection of fish diseases.

The method of use provided by the invention facilitates limiting the culture area to a designated area or can effectively prevent the installation of the system from affecting the water level of the water body.

When the conveyor belt 31 rotates, the driving surface of the conveyor belt 31 is driven from the lower side to the upper side. Thus, when the system is in operation, the water body passes through the conveyor belt 31, and the debris or fish in the water body is received by the conveyor belt 31. After the barrier, the fish escapes from the conveyor belt 31 under the stress of the organism, and is confined within the culture area, and the debris is separated from the water body by the conveyor belt 31, so as to remove the impurities in the water body and avoid miscellaneous. The object of the invention is that the structure provided by the invention can effectively remove the debris in the water body from the water body without affecting the normal flow of the water in the river 4 or the ditch and ensuring the daily activity of the fish.

Example 2:

As shown in FIG. 1 to FIG. 7 , the present embodiment is further defined on the basis of Embodiment 1: as a further technical solution for the above-mentioned water storage and slag removal system for river 4 ecological fish culture:

As a specific implementation of the conveyor belt 31, the conveyor belt 31 is composed of a plurality of mutually parallel tie bars 311 and a plurality of mutually parallel partition plates 312. The plurality of tie bars 311 are sequentially connected in series to form a closed ring. The adjacent straps 311 are hingedly connected, and the partitioning plates 312 are fixedly spaced on the straps 311, and the longitudinal direction of the partitioning plates 312 is located in the width direction of the conveyor belt 31, and the spacing between adjacent partitioning plates 312. It is used for the gap through which water flows. The above adjacent tie bars 311 are hingedly connected so that the adjacent tie bars 311 can be relatively rotated to smoothly pass through the roller 32, and the cavity structure formed between the inner side faces of the adjacent partition plates and the tie bars 311 is used as The area for accommodating the foreign matter, or the surface of the conveyor belt 31 of the above form and the surface of the debris can generate a large static friction factor, so that the movement of the debris with the conveyor belt 31 finally completes the separation of the debris from the water body. In this embodiment, the upper partition plates 312 are all made of steel strips having a thickness of 3 mm, and the surface of the steel surface is subjected to anti-corrosion treatment such as painting or galvanizing, the spacing of the partitioning plates 312 is 20 mm, and the length of the strips 311 is 10 mm. The steel strip with anti-corrosion treatment on the surface, the welded ring at both ends is used as a hinge member, and the hinge shaft is arranged between the rings, and a serrated notch is arranged on the working surface side of the partition plate 312, so that the partition plate 312 and the partition plate are provided. A large interaction force can be generated between the objects.

Especially in the flood season, the vegetation residue in the water body may be bulky, so that when the partition plate 312 is in contact with the residue, the partition plate 312 and the tie bar 311 have sufficient joint strength to achieve the above disability. For transport of the body, the conveyor belt 31 has a plurality of said rings in the width direction, and each of the partition plates 312 has a fixed connection point with each ring.

As a specific implementation of the roller 32, there are two rollers 32 between adjacent side piers 1, two rollers 32 are parallel to each other, one of the rollers 32 is disposed at the bottom of the side pier 1, and the other The roller 32 is disposed above the side pier 1 and the line connecting the axes of the two rolls 32 is at an angle of between 15 and 40 degrees from the horizontal. In the present solution, the angle between the line connecting the axis of the roller 32 and the horizontal plane is defined to limit the inclination of the working surface of the conveyor belt 31. If the above inclination is too small, it is necessary to set the working surface of the conveyor belt 31 relatively. Long to adapt to the depth change of the water body, if the inclination angle is large, this will cause the density of impurities to move with the conveyor belt 31, and can not separate the defects from the water body, so the above angle is selected as the length of the conveyor belt 31 to meet the water depth change, And with most of the impurities being able to move with the conveyor belt 31, a shorter length of conveyor belt 31 can be used.

In this embodiment, in order to facilitate the installation, maintenance, and the like of the system, a side wall of the side pier 1 is further provided with a descending groove 11 starting from the top end of the side wall and ending at the bottom end of the side pier 1, the descending groove 11 The bottom part is provided with a bearing seat mounting plate, and the bearing seat mounting plate is welded with a mounting stud. The structure facilitates the detachable connection between the lower roller 32 and the bearing seat on the roller 32 as a whole. In the form of pre-fixed studs, the above-mentioned integral connection with the bearing seat mounting plate can be completed by the nut, and at the same time, the free end of the stud is located between the two ends of the nut after the completion of the nut connection, so that the protection can be achieved. The role of the thread under the meshing state is convenient for the next disassembly. Further, the bearing housing on the roller 32 is axially waterproofed by the roller 32 and the components of the bearing housing are statically sealed and waterproofed.

As a person skilled in the art, the above-mentioned descending groove 11 may also be in the form of a hole provided on the side pier 1 for mounting the roller 32, and a manhole is provided at the same time.

The higher side of the stepped surface of the above-mentioned bottom pier 6 is preferably disposed upstream of the water flow to prevent the enrichment of the sediment, the fine stones, and the like at the lower roller 32 from causing excessive resistance to the rotation of the conveyor belt 31.

In this embodiment, in order to facilitate the construction during the installation process of the system, a water main pipe 5 is disposed below the bottom pier 6 or the bottom pier 6, and the connecting flange is welded on the upper water pipe 5, so that during the construction process of the system, The water from the upstream can be removed through the water pipe 5 to control the water level to complete the entire construction. The above connecting flange is used to connect the blind plate after the installation of the system is completed, so as to switch the working state of the water pipe 5 as needed.

Due to the action of water flow or debris, the working surface of the conveyor belt 31 will inevitably bend toward the downstream side with a small curvature, and the above bending is greater when the density of the debris is large or the local water body has a large flushing force. It is particularly obvious that the above bending causes the sundries and the working surface of the conveyor belt 31 to be steeper, which is not conducive to the smooth movement of the debris with the conveyor belt 31.
