Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment technology, specifically to a bottom-pushing device for temporary fish holding ponds. Background Technology

[0002] The long-distance transportation of live aquatic products mainly involves two technical stages: temporary holding and distribution. The purpose of temporary holding is to reduce the fish's activity level and allow them to adapt to a high-density farming environment, preparing them for subsequent distribution. Achieving high-density temporary holding within a defined water space requires three conditions: low temperature, an efficient dissolved oxygen supply system, and good water quality. After temporary holding, live aquatic products can expel feces and urine, firm up their muscles, and improve their meat quality and overall condition, adapting to the high-density, long-distance, and long-duration transportation environment. This is a necessary stage before transporting live aquatic products. Therefore, temporary holding is a crucial step in improving the survival rate during transportation, enhancing the vitality of aquatic products, and maintaining their freshness and flavor.

[0003] However, if the temporary holding period is too long, the water quality in the holding tank will deteriorate over time, producing many impurities that negatively impact the living environment. Traditionally, the wastewater in the holding tank is drained and replaced with fresh water to maintain water quality, wasting water and requiring a lot of labor. Furthermore, existing waste in the holding tank often accumulates at various points on the bottom and cannot be removed promptly. Prolonged stagnation of waste at the bottom inevitably has a detrimental effect on the farmed animals. Manual removal of this waste is time-consuming and labor-intensive. Summary of the Invention

[0004] The purpose of this invention is to provide a bottom-pushing device for temporary fish holding ponds, which can prevent dirt from remaining at the bottom of the pond and effectively remove impurities from the water.

[0005] The technical solution adopted by this utility model is as follows: A bottom-pushing device for a temporary fish holding pond includes a temporary holding pond, a bottom-pushing pipe, and a sewage discharge mechanism. The temporary holding pond has a horizontal bottom surface and a side wall perpendicular to the bottom surface. The bottom surface and the side wall form a circular pond structure. The bottom-pushing pipe is installed at the bottom of the temporary holding pond. The bottom-pushing pipe has a notch forming an inlet end and an outlet end. A water inlet pipe is connected to the inlet end. The water inlet pipe passes over the side wall and enters the temporary holding pond, connecting with the inlet end of the bottom-pushing pipe. Multiple water outlet nozzles are provided on the bottom-pushing pipe. The multiple water outlet nozzles are evenly distributed on the bottom-pushing pipe. One water outlet nozzle is installed at the outlet end of the bottom-pushing pipe, and the water outlet nozzle is installed on the bottom-pushing pipe at a certain angle. The sewage discharge mechanism includes a sewage discharge tank and a sewage discharge pipe. The sewage discharge tank is installed on the outer side wall of the temporary holding pond. The sewage discharge pipe is received at the bottom end of the sewage discharge tank and extends through the side wall into the interior of the temporary holding pond. The front end of the sewage discharge pipe is located at the center of the temporary holding pond.

[0006] Furthermore, the inlet pipe is connected to a water pump and valves.

[0007] Furthermore, the installation angle is set according to the number of water nozzles, and its calculation formula is R=360 / n, where R is the installation angle and n is the number of water nozzles.

[0008] Furthermore, the sewage tank is equipped with a drain pipe, and the drain pipe is equipped with a valve.

[0009] Furthermore, the portion of the sewage pipe located inside the temporary holding tank is a semi-circular pipe, which covers the bottom surface.

[0010] Furthermore, the sewage tank has a square tank structure, with its top slightly lower than the top of the outer wall.

[0011] Compared with the prior art, the beneficial effects obtained by this utility model are as follows:

[0012] This invention has a simple structure. By setting an annular bottom push pipe in the temporary holding tank and installing multiple inclined nozzles on the bottom push pipe, the water sprayed from the nozzles can drive the water in the temporary holding tank to rotate, so that the impurities contained in the water can gather towards the center and be easily discharged, thereby preventing the dirt from staying at the bottom of the tank, effectively removing impurities from the water and improving the survival rate of the aquaculture.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0017] like Figures 1-2 As shown, a bottom-pushing device for a temporary fish holding pond includes a temporary holding pond 1, a bottom-pushing pipe 2, and a sewage discharge mechanism 3. The temporary holding pond 1 has a horizontal bottom surface 11 and a side wall 12 perpendicular to the bottom surface. The bottom surface 11 and the side wall 12 form a circular pond structure. Water is supplied to the temporary holding pond 1 so that fish and other aquatic animals can be temporarily held in the temporary holding pond 1.

[0018] The bottom push pipe 2 is installed at the bottom of the temporary holding tank 1. The bottom push pipe 2 is used to inject water and provide the power to propel the water flow. Preferably, the bottom push pipe 2 is installed at the connection between the side wall 12 and the bottom surface 11. The bottom push pipe 2 has a notch forming an inlet end and an outlet end. A water inlet pipe 4 is connected to the inlet end. The water inlet pipe 4 passes over the side wall 12 and enters the temporary holding tank 1, connecting with the inlet end of the bottom push pipe 2. Water enters the bottom push pipe 2 from the inlet end. The water inlet pipe 4 is equipped with a water pump and a valve. The water pump provides pressure to the incoming water, enabling it to propel the water flow in the temporary holding tank 1. The water inlet pipe 4 supplies water to the temporary holding tank, facilitating water replacement and maintaining the water quality. The water in the pool is clean; multiple water outlet nozzles 21 are provided on the bottom push pipe 2, and the multiple water outlet nozzles 21 are evenly distributed on the bottom push pipe 2. One of the water outlet nozzles 21 is installed at the outlet end of the bottom push pipe 2, and the water outlet nozzle 21 is installed on the bottom push pipe 2 at a certain angle. Preferably, the installation angle is set according to the number of water outlet nozzles 21, and the calculation formula is R=360 / n, where R is the installation angle and n is the number of water outlet nozzles 21. In this embodiment, when the number of water outlet nozzles 21 n is 6, the installation angle of the water outlet nozzle 21 is 60 degrees. When the water inlet pipe 4 is opened, water is sprayed out from the water outlet nozzle 21, which drives the water in the temporary holding pool 1 to rotate.

[0019] The sewage discharge mechanism 3 includes a sewage discharge tank 31 and a sewage discharge pipe 32. The sewage discharge tank 31 is installed on the outer wall 12 of the temporary holding tank 1. The sewage discharge tank 31 has a square tank structure, with its top slightly lower than the top of the outer wall 12. The sewage discharge tank 31 is used to temporarily store water containing impurities. The sewage discharge pipe 32 is connected to the bottom end of the sewage discharge tank 31 and extends through the side wall 12 into the interior of the temporary holding tank 1. The front end of the sewage discharge pipe 32 is located at the center of the temporary holding tank 1. The portion of the sewage discharge pipe 32 inside the temporary holding tank 1 is a semi-circular pipe, which covers the bottom surface 11. Water in the temporary holding tank 1 can enter the sewage discharge tank 3 through the sewage discharge pipe 32. The design of the sewage tank 31 and sewage pipe within the 1-section allows the sewage tank 31 to create a siphon effect with the temporary holding tank 1. Water containing impurities in the temporary holding tank 1 can enter the sewage tank 31 through the sewage pipe 32, and the water level in the sewage tank 31 can reach the same level as the water level in the temporary holding tank 1. The sewage tank 31 is equipped with a drain pipe for discharging water from the sewage tank 31. A valve is installed on the drain pipe, and the water level in the sewage tank 31 can be controlled by adjusting the valve. The drain pipe is connected to the purification equipment. The water containing impurities in the sewage tank 31 is discharged into the purification equipment through the drain pipe for purification treatment and then recycled.

[0020] The working principle of this utility model is as follows:

[0021] Open the valve on the inlet pipe 4, and the water enters the bottom push pipe 2 from the inlet pipe 4. Under the action of water pressure, the water is sprayed out from the water outlet nozzle 21 and enters the temporary holding tank 1. Since the multiple water outlet nozzles 21 are designed in a certain angle and surround each other, the sprayed water can drive the water in the temporary holding tank 1 to rotate. The centripetal force generated by the rotation of the water causes the impurities contained in the water to gather towards the center and enter the sewage tank 31 from the sewage tank 31, and then be discharged through the drain pipe.

[0022] This invention has a simple structure. By setting an annular bottom push pipe in the temporary holding tank and installing multiple inclined nozzles on the bottom push pipe, the water sprayed from the nozzles can drive the water in the temporary holding tank to rotate, so that the impurities contained in the water can gather towards the center and be easily discharged, thereby preventing the dirt from staying at the bottom of the tank, effectively removing impurities from the water and improving the survival rate of the aquaculture.

[0023] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
