Description

Technical Field

[0001] The invention relates to the technical field of freshwater fish farming, in particular to a device for adjusting the water level of a fish pond. Background Art

[0002] Fish farming in fish ponds is an important part of agricultural production. The water level of the fish pond is closely related to the output of fish products. In the breeding process, it is often necessary to flexibly adjust the water storage and drainage of the fish pond according to different production seasons and precipitation conditions. In the rainy season, due to excessive rainfall, the fish pond must be drained in time. The structure of traditional fish ponds is very simple, and the drain outlet is usually made of stones and soil blocks. Water can only be stored by stacking and blocking the drain outlet. When draining, the drain outlet is dug with a hoe to let the excess water flow out of the fish pond. Such a drain outlet is not convenient for adjusting the water level of the fish pond, and there is also a safety hazard of causing major economic losses due to heavy rains washing out the drain outlet and a large number of fish escaping from the fish pond. Summary of the invention

[0003] The purpose of the present invention is to overcome the defects of the prior art and provide a device that can conveniently adjust the water level of a fish pond, thereby eliminating the potential safety hazard of heavy rain washing out the drainage outlet originally built and blocked with stones and soil blocks, causing a large number of fish to escape out of the fish pond and cause significant economic losses.

[0004] The technical solution of the invention is to design and manufacture a device for adjusting the water level of a fish pond, the device comprising a large sleeve, a small sleeve, a bearing, a screw rod, a sleeve and a handle.

[0005] The outer diameter ends of the upper left and right ends of the large sleeve are respectively provided with strip water outlet holes along the axial direction, the top of the strip water outlet hole is flush with the top of the inner cavity of the large sleeve, and the outer hole opening of the wall thickness of the strip water outlet hole is provided with a square boss adapted to the arc-shaped punched filter screen. The arc-shaped punched filter screen is welded and fixed on the square boss. A circular through hole is provided in the center of the top of the large sleeve, the outer diameter end of the bearing is tightly matched with the inner diameter of the circular through hole, and the lower end of the large sleeve is detachably fixedly connected to the drainage pipe extending to the outside of the fish pond through a live joint.

[0006] The large sleeve is used to cover the small sleeve. The outer diameter ends of the upper left and upper right ends of the large sleeve are respectively used to set the strip water outlet hole and the arc-shaped punching filter net. The center of the top of the large sleeve is used to set the bearing; the strip water outlet hole is used to let the excess water in the fish pond flow into the cavity of the upper large sleeve through the strip water outlet hole; because the top of the strip water outlet hole is flush with the top of the inner cavity of the large sleeve, when the top of the small sleeve rises to the top of the inner cavity of the large sleeve, it is convenient to grasp the closing condition of the strip water outlet hole by the small sleeve; the square boss is used to weld and fix the arc-shaped punching filter net; the arc-shaped punching filter net is used to prevent the fish from escaping from the fish pond through the strip water outlet hole, and at the same time prevent the sundries such as water plants and leaves from entering the upper large sleeve. The cylindrical water outlet hole at the top of the small sleeve is blocked in the hollow cavity of the sleeve; the bearing, the outer diameter end of the bearing is tightly matched with the inner diameter of the round through hole, and the inner diameter of the bearing is tightly matched with the outer diameter end of the lower end of the sleeve, so that the sleeve can be flexibly rotated in the center of the top of the large sleeve; because the lower end of the large sleeve is detachably fixedly connected with the drainage pipe extending to the outside of the fish pond through a live joint, the water in the upper large sleeve cavity flows into the small sleeve cavity in the small sleeve through the cylindrical water outlet hole at the top of the small sleeve, and the water in the small sleeve cavity flows into the drainage pipe through the lower large sleeve cavity at the lower end of the inner cavity of the large sleeve and is discharged to the outside of the fish pond. The drainage pipe is fixedly connected with the live joint, which is convenient for installation, disassembly and maintenance of the present invention.

[0007] The small sleeve is upwardly sleeved in the large sleeve, the outer diameter of the small sleeve is 0.1-0.3mm smaller than the inner diameter of the large sleeve, the upper and lower heights of the small sleeve are greater than the upper and lower heights of the strip water outlet holes at the upper left and upper right ends of the large sleeve, a small round concave hole adapted to the plug column is provided in the center of the top end of the small sleeve, and a plurality of evenly distributed cylindrical water outlet holes are provided around the top opening of the wall thickness of the small round concave hole. When the small sleeve moves downward, an upper large sleeve cavity is formed between the top end of the small sleeve and the top end of the inner cavity of the large sleeve, the water in the fish pond flows into the upper large sleeve cavity through the strip water outlet holes at the upper left and upper right ends of the large sleeve, the water in the upper large sleeve cavity flows into the small sleeve cavity in the small sleeve through the cylindrical water outlet hole at the top end of the small sleeve, and the water in the small sleeve cavity flows into the drain pipe through the lower large sleeve cavity at the lower end of the inner cavity of the large sleeve and is discharged outside the fish pond.

[0008] The small sleeve is sleeved in the large sleeve. Since the outer diameter of the small sleeve is 0.1-0.3mm smaller than the inner diameter of the large sleeve, it can flexibly rise or fall in the large sleeve. Since the upper and lower heights of the small sleeve are greater than the upper and lower heights of the strip water outlet holes at the upper left and upper right ends of the large sleeve, no matter the small sleeve rises or falls in the large sleeve, it can ensure that the small sleeve closes the strip water outlet holes at a certain water level. The center of the top of the small sleeve is used for welding the plug at the bottom end of the fixing screw. The cavity of the upper large sleeve is convenient for accommodating water entering the upper end of the inner cavity of the large sleeve from the strip water outlet holes. The cylindrical water outlet hole is convenient for the water in the cavity of the upper large sleeve to be discharged downward in time.

[0009] The top end of the screw rod extends downward to form a plug column, the diameter of the plug column is smaller than the diameter of the screw rod, the plug column is inserted downward into the small circular concave hole in the center of the top end of the small sleeve and welded together, and the axis of the screw rod and the plug column is the same as the axis of the large sleeve, the small sleeve, the small circular concave hole and the bearing.

[0010] The screw rod is used to drive the small sleeve to rise or fall in the large sleeve; the plug post is used for fixed connection between the screw rod and the small sleeve.

[0011] A large circular concave hole adapted to the sleeve is provided in the center of the bottom end of the handle, and the sleeve is inserted upward into the large circular concave hole and welded together. A strip observation hole is provided axially at the outer diameter end in the middle of the right end of the sleeve, and the upper and lower heights of the strip observation hole are slightly larger than the upper and lower heights of the strip water outlet holes at the upper left and upper right ends of the large sleeve. The rear end of the outer surface of the orifice of the wall thickness of the strip observation hole is provided with intervally arranged scale coatings from top to bottom along the upper and lower height directions of the strip observation hole, and numbers from small to large are respectively provided for indicating the distance between the top of the small sleeve and the top of the strip water outlet hole. The color of the scale coating is set to red or green, which is obviously different from the color of the sleeve. The sleeve is provided with an internal thread that cooperates with the external thread of the screw. The screw is screwed upward in the sleeve, and the outer diameter end of the lower end of the sleeve is tightly matched with the inner diameter of the bearing in the center of the top of the large sleeve.

[0012] The handle is used for holding and rotating by human hands, and for welding and fixing the sleeve. The sleeve is rotated by rotating the handle, and the rotation of the sleeve drives the screw to rotate, and the rotation of the screw drives the small sleeve to rise or fall in the large sleeve; the strip observation hole is used to observe the up and down movement of the screw in the sleeve, so as to understand the rise or fall of the small sleeve in the large sleeve, so as to grasp the sealing condition of the small sleeve to the strip water outlet hole, which is conducive to better adjusting the water level of the fish pond; the scale coating and the corresponding numbers are convenient for further and more accurately understanding the up and down movement of the screw in the sleeve; because the color of the scale coating is set to red or green, which is obviously different from the color of the sleeve, the scale coating is more eye-catching; the internal thread of the sleeve is used to cooperate with the external thread of the screw, and the screw is set in the sleeve so that the scale coating and the corresponding numbers can be set on the sleeve; because the outer diameter end of the lower end of the sleeve is tightly matched with the inner diameter of the bearing at the top center of the large sleeve, when the sleeve rotates, the large sleeve will not rotate with the sleeve, but can drive the screw to rotate.

[0013] Furthermore, the thickness of the arc-shaped perforated filter screen is set to 1 mm, and the aperture of the filter holes of the arc-shaped perforated filter screen is set to 5 mm.

[0014] The thickness of the arc-shaped perforated filter is set to 1mm, and the aperture of the filter holes of the arc-shaped perforated filter is set to 5mm. This design can prevent fish from escaping while meeting the filtering requirements of general freshwater fish farms for aquatic plants, leaves and other debris.

[0015] Furthermore, the large sleeve, small sleeve, screw, plug post, handle, sleeve and arc-shaped punched filter are all made of 204 stainless steel.

[0016] The large sleeve, small sleeve, screw, plug post, handle, sleeve and arc-shaped punched filter are all made of 204 stainless steel, which can prevent rust and extend the service life.

[0017] After the fish pond adopts the present invention, there is no need to pile up and block stones and soil blocks to form a drainage outlet. The water storage operation can be easily completed by turning the handle to timely and flexibly adjust the water level of the fish pond according to the technical requirements of freshwater fish breeding and different seasons, thereby eliminating the safety hazard of major economic losses caused by heavy rains washing out the drainage outlet and a large number of fish escaping out of the fish pond.

[0034] In the present invention, a series of products with different specifications are designed and manufactured to meet the actual production needs of a large number of freshwater fish farms.

[0035] The working conditions of the present invention are:

[0036] First, the drainage pipe is installed at the drainage outlet of the fish pond, and then the lower end of the large sleeve 8 of the present invention is movably fixed to one end of the drainage pipe near the edge of the fish pond by a flexible joint, so that the present invention is in an upright shape.

[0037] When in use, according to the requirement of the water level height of the fish pond, the handle 1 is rotated clockwise or counterclockwise, the rotation of the handle 1 drives the sleeve 16 to rotate, the rotation of the sleeve 16 drives the screw 17 to rotate, the rotation of the screw 17 drives the small sleeve 11 to rise or fall in the large sleeve 8, thereby adjusting the height of the orifice of the strip water outlet 7.

[0038] During operation, the movement of the screw 17 in the sleeve 16 is observed at any time through the strip observation hole 2 in the middle of the right end of the sleeve 16. By comparing the position of the top end of the screw 17 with the scale coating 20 and the number, the relative position of the top end of the small sleeve 11 and the strip water outlet 7 can be understood, thereby understanding the water outlet situation of the strip water outlet 7.

[0039] For example, when the number on the scale coating 20 corresponding to the position of the top of the screw 17 is 10, it means that the distance between the top of the small sleeve 11 and the top of the strip-shaped water outlet 7 is 10 cm.

[0040] When it is necessary to increase the water storage capacity of the fish pond and raise the water level of the fish pond, turn the handle 1 clockwise to make the small sleeve 11 rise in the large sleeve 8; when it is necessary to completely close the strip water outlet 7, continue to turn the handle 1 clockwise to make the top of the small sleeve 11 touch the top of the inner cavity of the large sleeve 8. At this time, the number on the scale coating 20 corresponding to the position of the top of the screw 17 is 0; when it is necessary to lower the water level of the fish pond, turn the handle 1 counterclockwise to make the small sleeve 11 descend in the large sleeve 8, and appropriately increase the water output of the strip water outlet 7; when a rainstorm is about to occur, turn the handle 1 counterclockwise to make the small sleeve 11 drop significantly in the large sleeve 8 until the number on the scale coating 20 corresponding to the position of the top of the screw 17 is 50, and the strip water outlet 7 is fully opened.

[0041] The water in the fish pond flows into the upper large sleeve cavity 14 through the strip water outlet hole 7, the water in the upper large sleeve cavity 14 flows into the small sleeve cavity 10 in the small sleeve 11 through the cylindrical water outlet hole 13 at the top of the small sleeve 11, and the water in the small sleeve cavity 10 flows into the drain pipe through the lower large sleeve cavity 9 at the lower end of the inner cavity of the large sleeve 8 and is discharged outside the fish pond.
