FIG. 2 is a top view (perspective view) of a fish collection tank for the vacuum pump of the present invention.
In the figure, 1, a fish inlet 2, an upper convex seal head 3, a one-way valve plate 4, a cylindrical barrel 5, a lower convex seal head 6, a fish outlet 7, supporting legs 8, supporting legs 9, an upper circular tube row 10, a lower circular tube row 11, a supporting beam 12, an air suction opening and an anti-overflow device are arranged.
Detailed Description
The invention is further described with reference to the following figures and specific examples.
Referring to fig. 1-2, a fish collecting barrel for a vacuum type fish suction pump comprises a barrel body 4, wherein a fish inlet 1 is arranged at the upper part of one end of the barrel body 4, and a fish outlet 6 is arranged at the lower part of the other end of the barrel body 4; the barrel 4 is horizontally arranged, one end of the barrel 4 is higher than the other end of the barrel, and the central shaft of the barrel 4 is inclined at a set angle with the horizontal plane; a transverse supporting beam 11 is arranged in the barrel 4, and a round pipe arrangement structure is arranged above the supporting beam 11 and comprises upper round pipe arrangements 9 which are arranged in parallel at intervals along the length direction and lower round pipe arrangements 10 which are arranged in parallel at intervals along the width direction; the front end of the round calandria structure is connected with the fish inlet 1; the rear end of the round calandria structure and the inside of the cylinder 4 are provided with a space for fish falling.
In this embodiment, referring to fig. 2, the support beam 11 is a pair of parallel cross bars.
In this embodiment, the barrel 4 has a cylindrical body, and the end covers at both ends are protruded.
In this embodiment, see fig. 2, the lower part of the barrel 4 is provided with legs, wherein a first leg 8 near the fish inlet 1 is longer than a second leg 7 near the fish outlet 6.
In this embodiment, see fig. 2, the upper round pipes 9 are spaced at the same distance from the lower round pipes 10, and are smaller than the width of the fish body.
In this embodiment, the round tube bank structure has a downward inclination angle from front to back, but the inclination angle is smaller than the inclination angle of the cylinder 4 itself. In fig. 1, the round gauntlet structure has a slightly downward sloping angle, but close to horizontal.
With continued reference to fig. 1-2, two rows of upper and lower circular tubes are arranged in the fish collecting cylinder near the fish inlet, a proper distance is kept between the circular tubes, and the upper and lower circular tubes are axially vertical. After water columns containing fish enter the fish collecting cylinder from the fish inlet and contact the round tube row at the upper part, the water columns are scattered by the round tube row, fish water separation is realized, water flow scattered by the round tube row at the upper part is further scattered after contacting the round tube row at the lower part, and the water flow falls into the existing water body in the fish collecting cylinder and then impacts the existing water body less, so that disturbance is not great. The fish after the fish water separation slides into the existing water body of the fish collecting cylinder from the tail end of the circular tube row at the upper part, and the impact on the existing water body is small. The water body in the fish collecting cylinder has no great disturbance, so that mutual friction and collision between fish in the water body are avoided, and the fish body is ensured not to be damaged.
Referring to fig. 1, the axial direction of the round tubes in the upper round tube row 9 should be consistent with the water column direction, and the axial direction of the round tubes in the lower round tube row 10 should be perpendicular to the water column direction. The round tubes in the upper round tube row 9 are connected with the round tubes in the lower round tube row 10 through welding. The upper surface of the supporting beam is connected with the round tubes of the lower round tube row by welding. The two ends of the supporting beam 11 are connected with the convex seal heads through welding.
In this embodiment, the axial distance between adjacent tubes should be appropriate to ensure that the water column is broken up, but not too densely.
In this embodiment, the surface of the round tubes in the upper round tube row 9 should be smooth, and if necessary, a layer of teflon may be coated on the outer surface of the round tubes.
In this embodiment, in order to facilitate the fish to slide off the upper row of tubes, the row of tubes should be at a small angle of inclination to the horizontal, preferably 3-5 ° towards the fish inlet and towards the fish outlet.
In this embodiment, the end of the circular tube row is spaced from the lower convex head 5 by a suitable distance to ensure that the fish do not collide with the lower convex head after sliding off the end of the circular tube row.
The above are preferred embodiments of the present invention, and those skilled in the art can make various changes or modifications based on the above description without departing from the general concept of the present invention, and such changes or modifications should fall within the scope of the present invention as claimed.
