Description

Technical Field

[0001] This utility model relates to the field of eel farming technology, and in particular to a water inlet device for eel farming ponds. Background Technology

[0002] Eels, also known as white eels or loaches, are a prized freshwater aquaculture fish. Their flesh is tender, delicious, and highly nutritious, possessing medicinal properties such as promoting blood circulation, nourishing the body, and regulating the body. Most existing eel farming ponds use simple pipe-connected or fixed-nozzle designs for their water intake systems. These systems typically connect a water pump directly to the intake pipe, allowing water to flow into the pond at a constant flow rate through the fixed nozzles.

[0003] An authorized publication number (CN220343271U) discloses a water inlet device for eel farming ponds, comprising an eel pond with a chamfered corner at the pond opening. A pipe support is fixedly connected to the top of the pond wall, and an inlet pipe is inserted into the inner side of the pipe support, with the inlet pipe's port located above the eel pond. The advantages of this invention are: the inlet pipe connects to a water pump; when the manual valve is opened, water exits the inlet pipe and directly impacts the bottom of the top surface of the guide plate, diverting the water flow and generating bubbles. A bracket is installed on the top of the eel pond wall, with a roller movably connected to the end of the horizontal section of the bracket. A wire roller is fixedly connected to the outer surface of the roller, rotating when impacted by the water flow, and the water flow is output to the wire roller. The device employs a hard, bristle structure; the sharp edges of the bristles have a greater cutting effect on the bubbles in the water flow, improving dissolved oxygen utilization, reducing aeration power consumption, and enabling the eel farming pond to generate sufficient oxygen simultaneously during water intake, reducing the power consumption and load of the oxygen supply device, thus saving energy and reducing emissions.

[0004] Regarding the aforementioned technologies, the existing water inlet device for eel farming ponds has the drawback that the constant flow rate of the water inlet method can easily lead to excessively strong or weak local water flow in the farming pond, affecting the habitat and growth of eels, having limited oxygenation effect, and making it difficult to ensure a uniform distribution of dissolved oxygen in the water. Therefore, this utility model provides a water inlet device for eel farming ponds. Utility Model Content

[0005] The purpose of this application is to provide a water inlet device for eel farming ponds to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A water inlet device for an eel farming pond includes a farming chamber. Multiple fixed plates are fixedly connected inside the farming chamber. Each fixed plate has a reciprocating assembly on its sidewall. Each reciprocating assembly includes a connecting shaft fixedly connected to the sidewall of the fixed plate. A rotating rod is rotatably connected to the sidewall of the connecting shaft. A limit groove is formed inside the rotating rod, and a connecting gear is fixedly connected to one end of the rotating rod. A sealing assembly is provided on the sidewall of the fixed plate.

[0008] Preferably, the sealing assembly includes a connecting block fixedly connected to the side wall of the fixing plate, and the connecting block has a sliding groove inside.

[0009] Preferably, a blocking rod is slidably connected inside the groove, and a plurality of toothed blocks are fixedly connected to the top of the blocking rod, the plurality of toothed blocks meshing with the connecting gear.

[0010] Preferably, a large gear is rotatably connected to the side wall of the fixed plate, and a rotating shaft is fixedly connected to the side wall of the large gear.

[0011] Preferably, the rotating shaft slides inside the limiting groove, and a small gear is rotatably connected to the side wall of the fixing plate.

[0012] Preferably, the pinion meshes with the gear, and the pinions are fixedly connected by the same connecting rod.

[0013] Preferably, the side wall of the breeding silo is fixedly connected with a plurality of water guide pipes adapted to the blocking rod, and the bottom of each water guide pipe is provided with a plurality of diaphragm-type pressure sprinkler heads.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] The reciprocating assembly utilizes a rotating shaft, rotating rod, limiting groove, and connecting shaft to achieve the reciprocating lateral movement of the blocking rod. The sealing assembly, through the cooperation of the blocking rod, toothed block, and connecting gear, seals the outlet at the end of the water guide pipe. By adjusting the motor speed to control the reciprocating speed of the blocking rod, the intermittent frequency of the water flow and the sealing duration are adjusted to trigger the automatic spraying of the diaphragm sprinkler head, thereby changing the flow pattern of the water entering the aquaculture tank and further increasing the oxygen content in the water.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Example 1: Reference Figure 1-4The device shown is an eel farming pond water inlet device, including a farming chamber 1, which holds the eel farming water and provides growth space for the eels. Multiple fixing plates 3 are fixedly connected inside the chamber. The fixing plates 3 serve to install and fix reciprocating components and sealing components, ensuring the stability of each component under water flow impact and providing a foundation for subsequent functions. Reciprocating components are provided on the side walls of the fixing plates 3. Each reciprocating component includes a connecting shaft 10 fixedly connected to the side wall of the fixing plate 3. The connecting shaft 10 serves as the axis of rotation of the rotating rod 12, limiting its rotation direction. The rotating rod 12 is rotatably connected to the side wall of the connecting shaft 10. Under external power, the rotating rod 12 rotates around the connecting shaft 10, converting circular motion into reciprocating oscillation, providing motion power to the connecting gear 9. A limiting groove 11 is provided inside the rotating rod 12 to limit its oscillation angle, preventing excessive oscillation and resulting in inaccurate motion. Simultaneously, in conjunction with the connecting shaft 10, it ensures the consistency of the oscillation trajectory of the rotating rod 12. A connecting gear is fixedly connected to one end of the rotating rod 12. 9. The connecting gear 9 rotates under the drive of the rotating rod 12. Through meshing with the tooth block 15, the swing of the rotating rod 12 is converted into the linear motion of the blocking rod 14. The side wall of the fixed plate 3 is provided with a blocking assembly, which includes a connecting block 13 fixedly connected to the side wall of the fixed plate 3. The connecting block 13 provides a sliding track and support structure for the blocking rod 14, ensuring that the blocking rod 14 can only move linearly within the preset groove, preventing it from deviating. The connecting block 13 has a groove inside, and the blocking rod 14 is slidably connected inside the groove. The blocking rod 14 is connected to the connecting gear 15. Under the meshing action of wheel 9 and toothed block 15, it makes reciprocating linear motion in the chute. By moving, it can block and open the water outlet at the end of the water guide pipe 6, and adjust the water flow into the breeding tank 1. Multiple toothed blocks 15 are fixedly connected to the top of the blocking rod 14. The multiple toothed blocks 15 mesh with the connecting gear 9. The toothed blocks 15 convert the rotational motion of the connecting gear 9 into the linear motion of the blocking rod 14, ensuring the accuracy and controllability of the blocking rod 14's motion. Through meshing transmission, the transmission ratio can be adjusted according to actual needs, thereby changing the movement speed and frequency of the blocking rod 14.

[0025] Example 2: Reference Figure 1-4Based on the same concept as in Embodiment 1 above, this embodiment further proposes that a large gear 7 is rotatably connected to the side wall of the fixed plate 3. The large gear 7 meshes with the small gear 8, achieving speed reduction through the gear transmission ratio. This converts the high-speed rotation of the small gear 8 into its own low-speed rotation, providing a stable and appropriately rotating power source for the rotating shaft 2. The rotating shaft 2 is fixedly connected to the side wall of the large gear 7. The rotating shaft 2, as an extension component of the rotation of the large gear 7, transmits the rotational motion of the large gear 7 to the rotating rod 12, causing the rotating rod 12 to swing around the connecting shaft 10. Sliding inside the limiting groove 11, the movement trajectory of the rotating shaft 2 is restricted by the cooperation with the limiting groove 11, ensuring the accuracy of the swing angle and range of the rotating rod 12. At the same time, the rotational motion of the rotating shaft 2 can be effectively converted into the swing of the rotating rod 12. The side wall of the fixed plate 3 is rotatably connected to a small gear 8, which meshes with a large gear 7. The small gear 8, with its small number of teeth, achieves high-speed rotation under the action of external power (such as a motor driving the connecting rod 4). By meshing with the large gear 7, it transmits power and reduces the speed to adapt to subsequent components. To meet the movement requirements, a connecting rod 4 is fixedly connected to each of the pinions 8. The connecting rod 4 connects multiple pinions 8 to ensure synchronous rotation of each pinion 8. It also serves as an input carrier for external power, transmitting the rotation of power sources such as motors to the pinions 8, ensuring the stability and consistency of power transmission. Multiple water guide pipes 6, adapted to the blocking rod 14, are fixedly connected to the side wall of the aquaculture tank 1. These water guide pipes 6 introduce external water into the aquaculture tank 1, providing the necessary water flow for eel farming. Their design, adapted to the blocking rod 14, allows the blocking rod 14 to pass through... The repeated motion seals and opens the outlet of the water pipe 6 to achieve intermittent control of the water flow, adjusting the frequency and flow rate of water entering the breeding tank 1. The bottom of the water pipe 6 is equipped with multiple diaphragm pressure sprinklers 5. When the outlet of the water pipe 6 is blocked by the blocking rod 14, the water pressure inside the pipe increases. The water pressure acts on the diaphragm, causing it to deform, and then the sprinkler head opens to spray water, spraying the water in a mist or fan shape, increasing the contact area between the water flow and the air, increasing the dissolved oxygen content of the water, and eliminating the need for additional oxygenation equipment, thus reducing energy consumption and costs.

[0026] The working principle of this device is as follows: When using this device, water is pumped into the water pipe 6 by an external water pump, and the water flows out from the end of the water pipe 6. The external motor is started to drive the connecting rod 4 to rotate, which in turn drives the small gear 8 to rotate. Through the meshing of the large gear 7 and the small gear 8, the large gear 7 drives the rotating shaft 2 to rotate, causing the rotating rod 12 to swing back and forth around the connecting shaft 10. Through the meshing between the connecting gear 9 and multiple tooth blocks 15, the blocking rod 14 moves back and forth, intermittently blocking the opening at the end of the water pipe 6. When the blocking rod 14 blocks the water pipe 6, the water pressure in the water pipe 6 increases, and the water flows out from the diaphragm pressure sprinkler head 5.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
