Description

Technical Field

[0001] The utility model relates to a breeding device, in particular to a parent fish seed preservation and wintering device. Background Art

[0002] Tilapia is a tropical fish that cannot tolerate low temperatures. The water temperature range for its life and growth is 16℃~40℃, and the optimum temperature is 26~30℃. It will die when the water temperature drops below 12℃. Under normal circumstances, when the water temperature drops to 16℃, wintering measures should be taken to ensure that the tilapia survives the winter smoothly.

[0003] To this end, the commonly used wintering methods are: 1. Using factory waste heat to winterize, that is, building a breeding pond near the factory, and then leading hot water pipes from the factory to the outside to regulate the water temperature in the breeding pond. It can be seen that this method has location restrictions. 2. Building a plastic cover shed for wintering, that is, building a plastic cover shed on the top of the breeding pond. Although the top of the breeding pond is covered, the heat preservation capacity is relatively weak, and the water temperature of the breeding pond is difficult to maintain above 16°C for a long time.

[0004] In addition, the above two overwintering methods do not have the ability to realize small water bodies, high density, and intelligent control of water temperature in the temperature-controlled overwintering pool for broodstock preservation, which makes the overwintering of subtropical fish such as tilapia and seed preservation in winter pose a high risk.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1-2 As shown, a parent fish seed preservation and wintering device includes a breeding pool 13, a heat pipe 18, a microporous aeration pipe 20, a blower 22, a water pusher 26, a hanging rack 27, a hot water device and a control module. The breeding pool 13 is equipped with a water quality monitoring system 29 and a temperature controller 10, and the water quality monitoring system 29 includes a pH tester, a nitrite detector, and a dissolved oxygen detector. The heat pipe 18 is installed at the bottom of the breeding pool 13. The microporous aeration pipe 20 is provided with a plurality of micropores 21 at intervals, is installed near the middle and lower part of the breeding pool 13, and is fixed on the inner wall of the breeding pool 13. The blower 22 is installed near the breeding pool 13, and is connected to the microporous aeration pipe 20 to supply air to the microporous aeration pipe 20. The hot water device is installed near the breeding pool 13, and is connected to the heat pipe 18 to supply hot water to the heat pipe 18. One end of the hanging rack 27 extends into the breeding pool 13 and is connected to the water pusher 26, and the other end is suspended on the top edge of the breeding pool. The water quality monitoring system 29 , the temperature controller 10 , the blower 22 , and the hot water device are all communicatively connected to the control module 31 .

[0029] The temperature controller 10 monitors the water temperature in the breeding pond 13 in real time, and transmits the monitored water temperature data information to the control module.

[0030] The pH tester, nitrite detector, and dissolved oxygen detector are all connected to the control module 31. The pH tester is used to monitor the pH value of the water in the breeding pond. The nitrite detector is used to monitor the nitrite concentration of the water in the breeding pond. The dissolved oxygen detector is used to monitor the dissolved oxygen content of the water in the breeding pond. The data information monitored by the pH tester, nitrite detector, and dissolved oxygen detector is transmitted to the control module 31.

[0031] The control module is equipped with a touch screen, which can display the water temperature, pH value, nitrite concentration, dissolved oxygen content, etc. of the aquaculture pond water. The control module can intelligently control the operation of the hot water device, the blower, and the supply of hot water to the heat pipe by the hot water device.

[0032] A mounting structure of the microporous oxygenation tube 20 is provided. Figure 1 As shown, the microporous aeration pipes are distributed and installed along the side of the culture pond, and the microporous aeration pipes 20 are installed on the side wall of the culture pond through a plurality of pipe clamp frames 37 .

[0033] A method for installing the heat pipe is provided: the heat pipe 18 is spaced 50 to 60 cm from the wall of the culture pond. The optional spacing is 50, 55 or 60 cm. The heat pipe is used to exchange heat with the water in the culture pond, thereby regulating the water temperature in the culture pond, so that the water temperature in the culture pond can be maintained within the set temperature range even in low temperature weather such as winter. For example, the water temperature in the culture pond can be regulated to 20 to 22°C, providing a suitable water temperature for tilapia broodstock in the culture pond.

[0034] The heat pipe can be made of 316L stainless steel pipe. Stainless steel pipe is corrosion-resistant and rust-free, which can extend the service life of the heat pipe.

[0035] The blower 22 is connected to the microporous oxygenation tube 20 through the air supply pipe 23, and can provide air to the microporous oxygenation tube 20 to increase the dissolved oxygen content of the aquaculture water in the aquaculture pool. The oxygenation working mode is: start the blower, the blower extracts air from the atmosphere and sends it into the air supply pipe, the air supply pipe then sends the air to the microporous oxygenation tube, and the air in the microporous oxygenation tube sprays air to the aquaculture water in the aquaculture pool through the multiple micropores 21 thereon, so as to increase the dissolved oxygen content of the aquaculture water. It is understandable that the number of micropores opened can be 10, 20, 30, 40, 50, 70, 80, 90, 100, 150, 200, 250, 300, etc. Therefore, when the aquaculture pool adopts high-density aquaculture, sufficient oxygen can also be given to the water body of the aquaculture pool.

[0036] The water pusher 26 is suspended and installed in the culture pond 13 through the hanging frame 27. The positional relationship between the water outlet end of the water pusher and the water surface of the culture pond can be: the first is that the water outlet end of the water pusher is immersed below the water surface of the culture pond. The second is that half of the water outlet end of the water pusher is immersed in water, and the other half is above the water surface. The water pusher pushes the water in the culture pond to flow, so that the water in the culture pond is running water.

[0037] like Figure 2 As shown, a structure of a suspension frame is given, which includes a support rod 272, a connecting rod 271 and an anti-slip rod 273. At least two connecting rods 271 are installed on the support rod 272 at intervals. The two connecting rods 271 are used to support and install the water pusher 26. One end of the support rod 272 is provided with a hook 2721, and the hook 2721 is connected to the anti-slip rod 273.

[0038] During installation, the support rod 272 is placed in the breeding pond, the hook 2721 is sleeved on the top of the pool wall of the breeding pond, the anti-slip rod 273 is placed on the outer side of the breeding pond, and the support rod, the hook and the anti-slip rod are combined and sleeved on the top of the pool wall of the breeding pond, which can stably support the water pusher in the breeding pond.

[0039] One structure of the water pusher may be an air-propelled water pusher. Air-propelled water pushers are commercially available. Figure 1 As shown, the water pusher is connected to the air supply pipe 32, and the air supply pipe 32 is equipped with an air valve 33. When the air valve 33 is opened, the air supply pipe 32 supplies air to the water pusher, and the water pusher pushes the aquaculture water to flow out from its water outlet. When the air valve 33 is closed, the air supply pipe 32 stops supplying air to the water pusher, and the water pusher stops working.

[0040] The hot water device can be used as a heat source to provide heat to the breeding pond and can regulate the water temperature in the breeding pond. It can overcome the problem that the existing breeding ponds are built based on factories and the problem that the plastic covering sheds of the existing breeding ponds have weak thermal insulation capacity. It can help the breeding ponds to be built in the right location according to the needs.

[0041] like Figure 1 As shown, a structure of a hot water device is given. The hot water device includes an air energy heat pump 1, a heat storage barrel 6 and a temperature sensor 30. The heat storage barrel 6 stores hot water, and the barrel wall of the heat storage barrel is a sandwich structure, that is, the barrel wall of the heat storage barrel is provided with a hollow interlayer 5, and the hollow interlayer is vacuum. It can block the heat exchange between the heat storage barrel and the external atmosphere, which is conducive to the heat storage barrel to achieve the heat preservation function.

[0042] like Figure 1As shown, a connection structure between an air energy heat pump and a heat storage tank is provided, and a first circulation pipe 2, a second circulation pipe 3 and a circulation pressure pump 4 are additionally installed. One end of the first circulation pipe 2 is connected to the outlet end of the air energy heat pump 1, and the other end is connected to the heat storage tank 6. One end of the circulation pressure pump 4 is connected to the inlet end of the air energy heat pump 1, and the other end is connected to the heat storage tank 6. The air energy heat pump 1, the first circulation pipe 2, the second circulation pipe 3, the circulation pressure pump 4 and the heat storage tank 6 form a closed water circulation connection.

[0043] The water circulation between the air energy heat pump and the heat storage tank works as follows:

[0044] The air energy heat pump 1 and the circulating pressure pump 4 are started, and the circulating pressure pump 4 draws water from the heat storage tank 6 through the second circulating pipe 3 and inputs it into the air energy heat pump 1. The air energy heat pump 1 heats the water sent therein to form hot water, and the hot water is pushed into the heat storage tank 6 through the first circulating pipe 2, which can heat the water in the heat storage tank and help keep the hot water in the heat storage tank within the set water temperature range.

[0045] In some embodiments, a connection structure between the heat storage tank and the heat conducting pipe is provided. A hot water pipe 8, a hot water booster pump 7, a solenoid valve 9 and a circulation pipe 11 are additionally installed. One end of the hot water booster pump 7 is connected to the heat storage tank 6, and the other end is connected to one end of the heat conducting pipe 18 through the hot water pipe 8; the solenoid valve 9 is installed on the hot water pipe 28 to control the hot water pipe 28 to be on and off; one end of the circulation pipe 11 is connected to the heat storage tank 6, and the other end is connected to the other end of the heat conducting pipe 18; wherein the hot water booster pump 7 and the solenoid valve 9 are both connected to the control module 31 for communication.

[0046] The temperature controller 10 monitors the water temperature in the breeding pond 13 in real time, and transmits the monitored water temperature data information to the control module.

[0047] Furthermore, in order to facilitate the control of the circulation pipe, a control valve 12 is additionally installed, and the control valve 12 is installed on the circulation pipe 11 to control the conduction and disconnection of the circulation pipe 11. When the control valve 12 is opened, the circulation pipe 11 is conducted. When the control valve 12 is closed, the circulation pipe 11 is disconnected. It is understandable that under normal conditions, the control valve is often in an open state.

[0048] One structure of the control valve 12 may be an electric control valve, which is communicatively connected with the control module 31 , and the control valve 12 can be controlled to work through the control module 31 .

[0049] The heating working mode of the heat pipe:

[0050] The hot water booster pump 7 extracts the hot water in the heat storage tank 6 and sends it to the hot water pipe 8. The hot water pipe 8 guides the hot water to the heat pipe 18. The heat pipe 18 is installed along the bottom edge of the culture pool and is arranged in parallel with the pool wall. The hot water guided in the heat pipe 18 exchanges heat with the water in the culture pool to heat the water in the culture pool, so that the temperature of the water in the culture pool rises. The heat pipe 18 sends the hot water after heat exchange to the circulation pipe 11, and the circulation pipe 11 sends the hot water after heat exchange to the heat storage tank 6. The temperature controller 10 monitors the water temperature of the culture pool in real time and transmits the water temperature data information to the control module 31 in real time. When the water temperature reaches the set upper temperature limit, the control module 31 controls the solenoid valve 9 to close and the hot water booster pump 7 to stop working; when the water temperature reaches the set lower temperature limit, the control module 31 controls the hot water booster pump 7 to start and the solenoid valve 9 to open, and the aforementioned work is repeated in this way.

[0051] The utility model realizes automatic monitoring and regulation of the water temperature of the breeding pond through a control module, a temperature controller, a solenoid valve, a hot water pressure pump and a heat storage barrel.

[0052] It should be noted that the temperature controller may be equipped with a display screen, and the hot water temperature value monitored by the temperature controller may be known through the display screen.

[0053] It is understandable that a temperature sensor 30 is installed on the heat storage barrel 6. When the water temperature in the heat storage barrel is detected to be lower than the set lower limit, the control module 31 controls the air energy heat pump 1 and the circulating pressure pump 4 to start. The circulating pressure pump 4 extracts the hot water in the heat storage barrel 6 through the second circulating pipe 3 and sends it to the air energy heat pump 1. The air energy heat pump 1 heats the hot water sent therein and sends it to the heat storage barrel 6 through the first circulating pipe 2, forming a circulating heating. When the water temperature monitored by the temperature sensor 30 reaches the set upper limit, the control module 31 controls the air energy heat pump 1 and the circulating pressure pump 4 to stop working.

[0054] In some embodiments, a structure for replenishing water to the heat storage tank is provided, and a liquid level sensor 36, a water replenishment pipe 35 and a water replenishment valve 34 are additionally installed. The water replenishment pipe 35 is connected to the heat storage tank 6, and a water replenishment valve 34 is installed on it; the liquid level sensor 36 is installed on the heat storage tank 6, and is used to monitor the liquid level height of the heat storage tank 6; wherein the liquid level sensor 36 and the water replenishment valve 34 are both connected to the control module 31 for communication.

[0055] The liquid level height of the heat storage tank can be pre-set on the control module, and the liquid level height value includes an upper limit value and a lower limit value of the liquid level.

[0056] Working method:

[0057] The water supply valve 34 is opened by the control module 31, and the water supply pipe 35 is connected to the heat storage barrel 6, and water is injected into the heat storage barrel 6. When the liquid level detected by the liquid level sensor 36 reaches the upper limit of the liquid level, the control module 31 controls the water supply valve 34 to close, and the water supply pipe 35 stops supplying water to the heat storage barrel 6. When the liquid level sensor 36 detects that the liquid level in the heat storage barrel is lower than the lower limit of the liquid level, the control module 31 controls the water supply valve 34 to open, and the water supply pipe 35 supplies water to the heat storage barrel 6. When the liquid level in the heat storage barrel reaches the upper limit of the liquid level, the control module controls the water supply valve to close, and the water supply pipe stops supplying water.

[0058] In some embodiments, in order to facilitate water replenishment in the culture pond, an additional water inlet pipe 24 and a water inlet valve 25 are installed. The water inlet pipe 24 is installed at the top of the culture pond 13 for replenishing water to the culture pond, and the water inlet valve 25 is installed on the water inlet pipe 24, and the water inlet valve 25 is used to control the opening and closing of the water inlet pipe.

[0059] When replenishing water, open the water inlet valve 25, the water inlet pipe 24 is opened, and water is replenished in the culture pond. When the liquid level in the culture pond rises to the required height, close the water inlet valve, and the water inlet pipe stops supplying water to the culture pond.

[0060] In some embodiments, in order to facilitate the drainage of the culture pond, a drain pipe 17 and a drain valve 16 are added. The bottom of the culture pond 13 is inclined downward toward the drain port 19 at an angle of 15° to 20°. The inclination angle can be selected as 15°, 16°, 17°, 18°, 19° or 20°. The bottom is inclined toward the drain port, which is conducive to drainage and uses the bottom water flow to push the residue in the culture pond to the drain port, which is convenient for regular drainage.

[0061] One end of the drain pipe 17 is connected to the drain port 19, and the other end is provided with a drain valve 16. When the drain valve 16 is opened, the water at the bottom of the culture pond enters the drain pipe 17 through the drain port, and the drain pipe 17 then guides the water outward to achieve drainage of the culture pond. When draining, the bottom of the culture pond tilts downward, and the debris and other debris at the bottom can be pushed to the drain port by the flow of water, and the debris can be discharged outward. When the water level of the culture pond drops to the required water level, the drain valve 16 is closed, and the drain pipe stops draining water outward.

[0062] In some embodiments, in order to facilitate the control of the liquid level in the culture pond, an overflow pipe 14 and a flange set 15 are additionally installed. The overflow pipe 14 is detachably connected to the drain valve 16 through the flange set 15.

[0063] The flange assembly 15 includes two flanges and a plurality of bolts. During installation, one flange is installed on the overflow pipe 14, and another flange is provided on the drain valve 16. The two flanges are butted, and a gasket is installed between the two flanges, and then fixedly connected by a plurality of bolts. The number of bolts can be 4, 6 or 8, etc.

[0064] It is understandable that when the liquid level in the breeding pond is higher than the height of the overflow pipe, the overflow pipe will discharge the breeding water to the outside in time, which can prevent the breeding water level in the breeding pond from being higher than the set water level.

[0065] It should be noted that the overflow pipe and the drain valve are detachably connected. When the aquaculture pond needs to be discharged, the overflow pipe and the drain valve can be disassembled and separated, and the drain valve can be opened so that the sewage at the bottom of the aquaculture pond can be discharged outside.

[0066] According to the above embodiments, the working mode of the utility model is as follows:

[0067] The heat storage tank stores hot water: the air energy heat pump 1 and the circulating pressure pump 4 are started by the control module 31. The circulating pressure pump 4 extracts the water in the heat storage tank 6 through the second circulation pipe 3 and inputs it into the air energy heat pump 1. The air energy heat pump 1 heats the water sent into it to form hot water. The hot water is pushed into the heat storage tank 6 through the first circulation pipe 2, which can heat the water in the heat storage tank and help keep the hot water in the heat storage tank within the set water temperature range. The temperature sensor 30 monitors the water temperature in the heat storage tank in real time. When the water temperature is lower than the set water temperature lower limit, the aforementioned heating work is performed. When the water temperature reaches the set water temperature upper limit, the heating work is stopped.

[0068] Regulating the temperature of aquaculture water: The hot water booster pump 7 is controlled by the control module 31 to work and the solenoid valve 9 is opened. The hot water booster pump 7 extracts the hot water in the heat storage tank 6 and sends it to the hot water pipe 8. The hot water pipe 8 sends the hot water to the heat pipe 18. The hot water flowing through the heat pipe 18 exchanges heat with the aquaculture water in the aquaculture pool to heat the aquaculture water and increase the water temperature of the aquaculture water. The heat pipe 18 guides the hot water into the circulation pipe 11, and the circulation pipe 11 sends the water back to the heat storage tank 6. The temperature controller 10 monitors the water temperature in the aquaculture pool in real time. When the temperature of the aquaculture water reaches the upper temperature limit (e.g., it can be set to 22°C), the control module 31 controls the hot water booster pump 7 to stop working and the solenoid valve 9 to close. When the temperature of the aquaculture water reaches the lower temperature limit (e.g., it can be set to 20°C), the control module 31 controls the hot water booster pump 7 to work and the solenoid valve 9 to open, and repeats the aforementioned heating of the aquaculture water.

[0069] Increase the dissolved oxygen content: The control module 31 controls the blower 22 to work, the blower 22 draws air and delivers the air to the air supply pipe 23, the air supply pipe 23 then delivers the gas into the microporous oxygenation pipe 20, and the multiple micropores 21 on the microporous oxygenation pipe 20 spray air into the breeding water to increase the dissolved oxygen content of the breeding water, thereby providing sufficient oxygen for the tilapia broodstock in the breeding pond.

[0070] Drainage of the breeding pond: separate the overflow pipe 14 and the drain valve 16, open the drain valve 16, and the breeding water at the bottom of the breeding pond enters the drain port 19, and is then guided outward by the drain pipe 17 to discharge, thereby achieving drainage and sewage discharge of the breeding pond.

[0071] The above embodiments are preferred implementation modes of the present invention and are only used to facilitate the explanation of the present invention. They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the relevant technical field, if they do not depart from the scope of the technical features of the present invention, can make equivalent embodiments by partial changes or modifications to the technical contents disclosed in the present invention, and they still fall within the scope of the technical features of the present invention without departing from the technical features of the present invention.
