Description

Culture fish pond, control system and control method

Technical Field

The invention belongs to the technical field of aquaculture, and particularly relates to a culture fish pond, a control system and a control method.

Background

Medium and large-sized aquaculture fisheries are usually constructed in outdoor environments due to large area. Compared with a closed indoor environment, the outdoor environmental factors are closer to nature, so that the growth and the life of fishes are more facilitated. And the construction of indoor farms has higher cost, so the selection of outdoor culture is the preferred choice of most fish culture personnel. However, in the existing outdoor culture fishery, a fish pond is usually directly opened up for culturing fish, and only manual simple culture work such as regular water changing, oxygen increasing, feeding and the like is carried out, so that the labor cost is consumed, and meanwhile, the outdoor culture fishery is not suitable for some poor environments, such as strong illumination in summer, fish are irradiated by ultraviolet rays for a long time, and the body function is easily greatly influenced. Furthermore, most of the common ornamental fishes need proper illumination for growth, but excessive illumination can affect the appearance of the fishes and the color of the fishes, i.e. excessive illumination is not beneficial to the cultivation of the ornamental fishes. In conclusion, although the growth of the fish and the animal cannot be lighted, the growth of the fish and the animal is not suitable for long-time lighting, and the duration and the intensity of the lighting can influence the fish.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention without any inventive step, are within the scope of protection of the invention.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a number" means two or more unless specifically limited otherwise.

The first embodiment is as follows:

the embodiment discloses a culture fish pond, which can automatically change fish activity areas by setting time arrangement, so that fishes can be arranged to be active and work according to culture requirements.

In the present embodiment, as shown in fig. 1 to 5, the fish pond includes a fish pond body 100, a sunshade cover 400, a fish net box 210, and a positioning net tray 220 slidably connected to the fish net box 210. The fish-turning net box 210 and the positioning net disk 220 both adopt a latticed plane structure which can freely flow the water in the pool. It should be understood that in practical application, the water-permeable holes in the grid-like planar structure are fish-impenetrable water-permeable holes, i.e. the space formed by the fish-trapping net box 210 and the positioning net disk 220 is ensured to trap the fish. The net positioning plate 220 and the fish-circling net box 210 form a movement limiting chamber 230 for fish movement, and the net positioning plate 220 changes the space size of the movement limiting chamber 230 through sliding on the fish-circling net box 210. The fishpond body 100 comprises a water containing chamber 110, and a movement limiting chamber 230 is placed in the water containing chamber 110. The sunshade cover 400 is slidably coupled to the top of the fish pond body 100, and the sunshade cover 400 changes a sunshade area by sliding on the top of the fish pond body 100.

As shown in fig. 1 and fig. 6, a solar cell panel 410 is fixedly installed on the top side of the sunshade cover 400 of the present embodiment, a storage battery 420 is installed outside the fish pond body 100, and the electric energy converted by the solar cell panel 410 is stored by the storage battery 420. The embodiment generates electric energy from the solar cell panel 410, and can avoid using an external power supply. When the problem that the power line cannot be simply installed around the fish pond due to factors such as topography and the like occurs, the power supply can be directly obtained from the storage battery 420, and the electric energy of the storage battery 420 is converted by the solar cell panel 410, so that the cost for laying the power line can be saved.

In this embodiment, as shown in fig. 2, a plurality of underwater slide rails 240 are fixedly arranged on the inner wall of the fish-enclosing net box 210, a plurality of underwater pulleys 221 are fixedly arranged on both sides of the positioning net disc 220, and the underwater pulleys 221 are embedded in the underwater slide rails 240. The underwater pulley 221 drives the positioning net disc 220 to slide on the fish-circling net box 210 by rolling on the underwater slide rail 240. The lower pulley is driven to rotate by a pulley motor M, which draws power from the battery 420. Each underwater slide rail 240 is further provided with a first positioning member 251 and a second positioning member 252. The first positioning member 251 and the second positioning member 252 are respectively fixed at two different positions on the underwater slide rail 240, and are used for defining a sliding area of the positioning net disk 220. In this embodiment, the first positioning element 251 is fixed at one end of the underwater slide rail 240 to prevent the positioning net disc 220 from scratching the underwater slide rail 240. The second positioning member 252 is fixedly disposed at the middle of the underwater sliding rail 240, and is used for preventing the positioning net disc 220 from sliding forward, so as to fix the size of the covered area and ensure that fish can move in a space with a suitable size. The sliding of the positioning net disk 220 on the underwater slide rail 240 is realized by the rotation of the pulley motor M, and when the positioning net disk 220 slides to the position of the first positioning element 251, the space of the activity limiting chamber 230 formed by the positioning net disk 220 and the fish-trapping net box 210 is the largest, and fish can freely swim in a sunshade area and a non-sunshade area. When the positioning net disk 220 slides to the position of the second positioning part 252, the movable limiting chamber 230 formed by the positioning net disk 220 and the fish-trapping net box 210 is in a sunshade area, and fish are limited to move in a dark environment, so that direct sunlight can be effectively avoided.

Specifically, as shown in fig. 5, a water pump 450 and an oxygen increasing pump 460 are further disposed inside the water containing chamber 110 of the present embodiment. The water pump 450 is disposed outside the activity limiting chamber 230 and is fixedly connected to the inner wall of the water containing chamber 110. The oxygenation pump 460 is placed in the water containing chamber 110 outside the activity limiting chamber 230. A first timing switch 430 for simultaneously controlling the operation time of the positioning net disk 220 and a second timing switch 440 for controlling the operation time of the water pump 450 are also included. The first timing switch 430 and the second timing switch 440 are both fixed outside the fish pond body 100. The first timing switch 430 is used for controlling the sliding of the positioning net disk 220 in a timing manner, namely, controlling the work and rest activities of the fishes in a timing manner. For example, in this embodiment, fish are controlled to receive light at seven to ten points in the morning and three to seven points in the afternoon at regular time, and fish are not suitable to move directly in the sun at three points from ten to afternoon because of the high ultraviolet intensity, so the first timing switch 430 can be set for time to drive the pulley motor M to rotate forward at regular time to drive the fish to the sunshade area; and the pulley motor M is rotated in a timing and reverse phase manner, so that sufficient space for fish to move in the sun is provided. The second timing switch 440 is used to time the operation time of the water pump 450. The water pump 450 is not suitable to be started when the fish have a rest, and the water pump 450 is started to change water at the moment, so that the normal activity and rest of the fish are easily disturbed. Thus, the water pump 450 is adapted to operate in situations where fish activity is active. When fish move about under the direct sunlight promptly, water pump 450 can start, and start water pump 450 this moment and trade water and can reduce the fish pond temperature, avoid the temperature of the temperature too high under the direct sunlight. However, since the water change work for the fish pond is not suitable for a long time every day in the culture process, the time range within which the water pump 450 can be started can be controlled in a timing manner by the second timing switch 440.

Specifically, as shown in fig. 1 and 5, two water slide rails 300 are fixedly arranged at the top of the fish pond body 100, a plurality of water pulleys 401 are fixedly arranged on both sides of the sunshade cover 400, and the water pulleys 401 are embedded into the water slide rails 300. The water pulley 401 slides on the water slide rail 300 to drive the sunshade 400 to slide on the fishpond body 100. When the state of the fish activity in the sunshade area needs to be observed, the observation is performed by sliding the sunshade cover 400 away from the original position.

In this embodiment, the resistance of the first resistor R1, the resistance of the second resistor R2, and the resistance of the third resistor R3 should be set such that the voltage at the common connection end of the first resistor R1 and the second resistor R2 is greater than 2/3 times of the power supply voltage (provided by the first transformer 510), and the voltage at the common connection end of the second resistor R2 and the third resistor R3 is less than 1/3 times of the power supply voltage (provided by the first transformer 510). In this embodiment, fig. 7 is a schematic diagram of circuit control only, only the key connection lines of the circuit control are drawn, and the remaining auxiliary components for assisting the normal operation of the circuit are not shown in fig. 7 of this embodiment, but those skilled in the art should understand that.

The working mode of the embodiment is as follows:

when the first timing switch 430 controls the double-selection switch K1 to select the common connection end of the first resistor R1 and the second resistor R2, the common connection end of the sixth pin and the second pin of the first 555 timer 610 is closed and conducted with the common connection end of the first resistor R1 and the second resistor R2, at this time, the third pin of the first 555 timer 610 outputs a low level, the first common connection end a inputs the low level, the voltage of the low level is less than the reference voltage, and at this time, the pulley motor M reversely rotates. Because the underwater sliding rail 240 is provided with the first positioning member 251, the positioning net disk 220 is kept at the position of the first positioning member 251, and the fish can move under the direct sunlight.

Because the low level of the third pin mouth output of first 555 timer 610 is still inputed to the public link that sixth pin mouth and the second pin mouth electric connection of second 555 timer 620 constitute, so the third pin mouth output high level of second 555 timer 620 when this, first triode Q1 switches on, pilot lamp 700 lights, and relay KA controls first contact c and third contact e to close. When the second timing switch 440 controls the second timing switch K2 to be closed, the water pump 450 is turned on at the moment to provide oxygen for the fish pond; when the second timing switch 440 controls the second timing switch K2 to be turned off, the water pump 450 is not turned on.

When the first timing switch 430 controls the double-selection switch K1 to select the common connection end of the second resistor R2 and the third resistor R3, the common connection end of the sixth pin and the second pin of the first 555 timer 610 is closed and conducted with the common connection end of the second resistor R2 and the third resistor R3, at this time, the third pin of the first 555 timer 610 outputs a high level, the first common connection end a inputs a high level, the voltage of the high level is greater than a reference voltage, and at this time, the pulley motor M rotates in the forward direction. Since the underwater sliding rail 240 is provided with the second positioning member 252, the positioning net disk 220 slides and is kept at the position of the second positioning member 252, and at this time, the fish can move only in the sunshade area.

Because the high level of the third foot mouth output of first 555 timer 610 is still input to the public link that sixth foot mouth and the second foot mouth electric connection of second 555 timer 620 constitute, so second 555 timer 620 third foot mouth output low level at this time, first triode Q1 does not switch on, pilot lamp 700 extinguishes, relay KA control first contact c and second contact d are closed, oxygenation pump 460 opens, provide oxygen for in the fish pond.

Example three:

the embodiment discloses a control method for a culture fish pond, which adopts the control system for the culture fish pond in the second embodiment and comprises the following steps:

the first timing switch 430 controls the pulley motor to rotate at regular time, so that the positioning net disc 220 moves and drives or does not drive fishes to the lower part of the sunshade cover 400;

when the fishes are driven under the sunshade cover 400, the oxygenation pump 460 is kept started and supplies oxygen, and the water pump 450 is kept closed;

when the fish are not driven under the sunshade 400, the oxygenation pump 460 is stopped and the water pump 450 is started to change water under the timing control of the second timing switch 440.

The above-described embodiment has the following advantages.

The embodiment can automatically control the activity and rest of the fishes according to the actual culture requirements, slide the positioning net disk 220 at the specified time, and change the activity area of the fishes through the sliding of the positioning net disk 220, thereby standardizing the activity and rest of the fishes. This embodiment can prevent that fish from receiving the danger of ultraviolet ray injury that the direct incidence of sunshine brought for a long time.

In the embodiment, when the fish receive the sunlight, the water pump 450 is started to change the water in the fish pond; when the fish do not receive the sunlight, the oxygenation pump 460 is started to oxygenate the fishpond. When the fish do not receive the sunlight, the fish may have a rest, and the water pump 450 should not be started, so that the oxygen supply of the fish is ensured by only starting the oxygenation pump 460.
