Description

Technical Field

[0001] This utility model relates to the field of conger eel farming technology, and more specifically, to a simulated ecological temporary holding pond for conger eels. Background Technology

[0002] The conger eel, also known as the star conger eel, starry glutinous eel, or sand eel, is a marine fish belonging to the genus Congere in the family Congeridae.

[0003] Currently, conger eels are placed in temporary holding tanks after being caught from the ocean, and the salinity is gradually adjusted to avoid death due to osmotic pressure imbalance caused by sudden changes in salinity. At the same time, the fish are prone to abrasions or infections during the catching and transportation process, and the temporary holding tanks provide a quiet environment for recuperation.

[0004] However, as migratory fish, conger eels rely on water flow for directional movement in their natural environment. The static water source in the current holding tanks cannot simulate the migration path to keep the conger eels moving at a certain level, which makes them prone to stress reactions and death. There is a lack of ecological holding tanks that can simulate the migration scenario. Utility Model Content

[0015] 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 a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments: like Figure 1 As shown, a simulated ecological temporary rearing pond for conger eels, pond body 1, The first suction pump 2 is fixed on the left side wall of the pool body 1, and the input pipe of the first suction pump 2 is connected to the bottom area inside the pool body 1. A first protective net is provided at the end of the input pipe of the first suction pump 2. One of the pipes of the four-way pipe 3 is connected to the output pipe of the first suction pump 2. The remaining three pipes of the four-way pipe 3 are each equipped with an independently operating solenoid valve 4. The remaining three pipes of the four-way pipe 3 are respectively connected to the front wall, rear wall and right wall of the pool body 1 through the delivery pipe 5. The rocks and bamboo tubes are placed on the bottom surface inside pool 1 (the rocks and bamboo tubes are not shown in the figure).

[0016] To further refine the above-described embodiments and allow conger eels to be cultured in a suitable temperature environment to more closely approximate natural environmental conditions, the following optimizations are made: Figure 2 As shown, a cover plate 6 is movably installed above pool body 1. The cover plate 6 is provided with a heat dissipation window 7, a heat insulation plate 8 that cooperates with the heat dissipation window 7 and slides with the cover plate 6, and a cold air fan 81. The cold air fan 81 is connected to the inside of the pool body 1. (Specifically, the cover plate 6 is provided with a sliding groove that slides with the heat insulation plate 8. The sliding groove is not numbered in the figure. The cold air fan 81 is existing technology and no improvement is made.) The inner wall of the pool body 1 is equipped with an electric heating rod 9 and a temperature sensor 10.

[0017] To facilitate the installation and removal of the cover plate 6, further optimizations to the above-described embodiments are made, such as... Figure 2 and Figure 3As shown, handles 11 are symmetrically arranged on the cover plate 6, and mounting plates 12 are symmetrically arranged on the cover plate 6 and the pool body 1. Fixing bolts are provided in the mounting plate 12, which are not shown in the figure.

[0018] To regularly filter and purify the water in the temporary holding tank to reduce the incidence of disease, further optimizations to the above-described embodiments are possible, such as... Figures 3 to 5 As shown, a second suction pump 13 is fixedly installed on the right side wall of pool 1. The input end of the second suction pump 13 is connected to a suction pipe 14 that passes through the pool body 1 and extends to the bottom of the pool body 1. The end of the suction tube 14 is provided with a second protective net (the second protective net is not shown in the figure). The output end of the second suction pump 13 is connected to the filter box 15. The filter box 15 is equipped with a filter assembly and a door 16 is rotatably connected to the filter box 15. (The locking of the door 16 and the filter box 15 can be achieved using existing technology, specifically magnetic adsorption. (The filter box 15 has a groove, a first magnet is installed in the groove, a second magnet that cooperates with the first magnet is installed on the door 16, and a sealing element is installed on the inner edge of the door 16. The groove, the first magnet, the second magnet, and the sealing element are not shown in the figure.) One end of the return pipe 17 is connected to the bottom of the filter box 15, and the other end of the return pipe 17 is connected to the inside of the pool body 1. A one-way valve that allows only inflow and no outflow is provided on the return pipe 17 (the one-way valve is shown in the figure but is not labeled). Specifically, the filter assembly includes a placement frame 151, a filter screen, and filter cotton. Several drainage holes 152 are provided on the bottom surface of the two placement frames 151 that are circumferentially attached to and welded to the inner wall of the filter box 15, and the two placement frames 151 are distributed vertically. The filter screen is placed in the upper placement frame 151 and is adapted to the inner wall of the upper placement frame 151, and the filter cotton is placed in the lower placement frame 151 and is adapted to the inner wall of the lower placement frame 151. The filter targets: Large particulate solid waste: uneaten bait, conger eel feces, etc.

[0019] Suspended organic matter: visible impurities such as algal clumps and plant residues.

[0020] Filter cotton filters out: Fine suspended matter: organic debris and bacterial aggregates with a particle size of 20~200μm.

[0021] To further ensure the smooth operation of the suction filtration and purification process, such as Figure 3 As shown, a guide platform 18 is inclined at the bottom of the pool 1 to realize the directional flow of water source so as to facilitate suction, transfer and purification, and rocks and bamboo tubes are set on the guide platform 18.

[0022] To meet the basic oxygen requirements of conger eel farming and effectively degrade toxic substances generated in the water during the farming process, further optimizations to the above-described embodiments are needed, such as... Figure 3 As shown, an air pump 19 is also installed on the side wall of the pool 1, which is connected to the inside of the pool 1. The air pump 19 is connected to a pure oxygen source (the oxygen source is not shown in the figure), and the oxygen content in the pool 1 is maintained at 6~8 mg / L.

[0023] It should be noted that the first suction pump 2, solenoid valve 4, air cooler 81, heating rod 9, temperature sensor 10, second suction pump 13, and air pump 19 are all electrically connected to the PLC controller, which is not labeled in the figure.

[0024] The working process of this utility model: First, conger eels caught from the ocean are placed in pool 1, and the salinity is gradually adjusted. Once the salinity is adjusted, the first suction pump 2 is controlled by the PLC controller to draw water from pool 1. At this time, the conger eels are effectively blocked by the first protective net. Currently, only one solenoid valve 4 on the four-way pipe 3 is open, while the remaining solenoid valves 4 are closed. After being transferred by suction, the water will return from one of the front / rear / right sides of pool 1. The return flow rate is 0.5-1 m / s. The suction pump is a variable frequency centrifugal pump, which is an existing technology and will not be improved. It can accurately control the return water flow rate. Its core principle is to change the impeller output performance by adjusting the motor speed, thereby dynamically adjusting the flow rate and pressure. After a pre-set time is set after one solenoid valve 4 is opened, other solenoid valves 4 can be switched on (at this time, only one solenoid valve 4 is still in the open state. This process is achieved by a relay in conjunction with a PLC controller. The automatic switching of multiple solenoid valves 4 in sequence is existing technology and will not be described in principle). The significance of this is that the water source can be alternately circulated back into the pool 1 from different positions in the pool. This allows the water in the temporary holding pool to flow to simulate the migration scenario (i.e., the water circulation simulates the experience of conger eels in the natural environment), thereby giving the conger eels a certain amount of exercise, which helps them maintain a healthy state, reduces the probability of the conger eels experiencing stress, and thus extends their lifespan. Based on this, the design of cover plate 6, heat dissipation window 7, heat insulation board 8, air cooler 81, electric heating rod 9 and temperature sensor 10 can create a relatively suitable and constant temperature environment (around 25-28 degrees Celsius). If the outside temperature is low, the heat dissipation window 7 is blocked and the electric heating rod 9 is controlled to raise the temperature to this range. If the outside temperature is high, the heat dissipation window 7 is opened to prevent the temperature from rising continuously. The air cooler 81 can also be used to cool down to this temperature range. In this way, the temperature of the breeding environment for conger eels is suitable and there will be no large fluctuations, thereby further simulating the temperature of the natural environment to extend the survival period of conger eels. However, with the cultivation of conger eels, feces and other impurities will be generated, polluting the water quality. The second suction pump 13 is then controlled by the PLC controller to periodically draw water from the temporary holding tank to the filter box 15 for filtration and purification of feces and other impurities. After purification, the water source is returned to the tank 1 to significantly reduce the pollution level in the conger eel farming area (extending the water change cycle). It should be noted that due to the presence of the second protective net, the conger eels can be blocked, and the suction is in a balanced state (water is flowing out and water is flowing in at the same time), so the farming and storage of conger eels is not affected while dynamically removing impurities. In addition, reefs were set up in pool 1 to create a seabed-like terrain, and bamboo tubes were provided for the conger eels to hide in, thus making it closer to the natural ecological environment and maximizing the quality of the temporary holding environment for the conger eels to improve their survival rate.
