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-trapping net box 210 and the positioning net disk 220 both adopt a latticed plane structure which can freely circulate 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 positioning net disk 220 and the fish-trapping net box 210 form a movement limiting chamber 230 for fish movement, and the positioning net disk 220 changes the space size of the movement limiting chamber 230 through sliding on the fish-trapping net box 210. The fishpond body 100 includes a water containing chamber 110, and a movement restricting chamber 230 is disposed 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, the inner wall of the fish-catching net box 210 is fixedly provided with a plurality of underwater slide rails 240, two sides of the positioning net disc 220 are respectively fixedly provided with a plurality of underwater pulleys 221, and the underwater pulleys 221 are embedded into 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 coupled to the inner wall of the water storage 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.

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 and the common connection end of the first resistor R1 and the second resistor R2 are closed and conducted, at this time, the third pin of the first 555 timer 610 outputs a low level, the first common connection end a inputs a low level, the voltage of the low level is less than the reference voltage, and at this time, the pulley motor M rotates reversely. 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 the first 555 timer 610 is still input to the public connection end formed by the electrical connection of the sixth pin mouth and the second pin mouth of the second 555 timer 620, the third pin mouth of the second 555 timer 620 outputs the high level at this time, the first triode Q1 is conducted, the indicator lamp 700 is turned on, and the relay KA controls the first contact c and the third contact e to be closed. When the second timing switch 440 controls the second switch K2 to be closed, the water pump 450 is turned on to provide oxygen for the fish pond; when the second timing switch 440 controls the second 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 and the common connection end of the second resistor R2 and the third resistor R3 are closed and conducted, 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 the reference voltage, and at this time, the pulley motor M rotates in the forward direction. Due to the second positioning part 252 on the underwater sliding rail 240, the positioning net disk 220 slides and keeps the position of the second positioning part 252 still, and at the moment, the fish can only move 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 III

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 not 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 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.
