Description

Technical Field

[0001] The utility model belongs to the technical field of fish farming, and particularly relates to a fish pond structure for fish farming in paddy fields. Background Technique

[0002] By using the water surface of paddy fields to raise fish, not only can fish products be obtained, but also fish can eat pests and weeds in the paddy fields, excrete manure, and turn over the soil to promote the decomposition of fertilizers, creating good conditions for the growth of rice. Due to the shallow water in paddy fields, the water temperature is greatly affected by the air temperature. Under the scorching sun in summer, the water temperature can sometimes reach as high as 40°C, seriously affecting the growth of fish. Due to different rice planting densities, it is necessary to reasonably plan the fish ponds for fish to rest and the fish channels for fish to swim.

[0003] The patent document with the publication number CN207075332U discloses a fish farming ecosystem in paddy fields. The fish farming ecosystem in paddy fields mainly includes a paddy field planting area, fish ponds, fish channels, a reservoir, a water inlet pipe, a water inlet, a fish blocking net, a shading net, a water temperature controller, a water inlet pump, an oxygenation pump, a PH controller, a temperature sensor, a PH value sensor, an oxygen content sensor, a water level sensor, a fish pond lower computer, a serial communication module, and a handheld terminal. The utility model provides a fish farming ecosystem in paddy fields, which can greatly reduce the application of chemical agents such as pesticides and fertilizers, effectively protect the agricultural ecological environment, can monitor the water quality of paddy fields in real time, and maximize the guarantee of the best environment for the growth of rice and fry; at the same time, it can avoid damage to the fish ponds due to weather conditions and cause unnecessary losses to the growth of fry. However, this system fails to solve the technical problem of setting different fish channels according to the area of paddy fields to avoid fish congestion.

[0004] The patent document with the publication number CN204968624U discloses a structure for fish farming in paddy fields, including a paddy field and a water treatment system.

[0026] As Figure 1 shown, the fishpond structure for fish farming in paddy fields includes a main body of the fishpond 1, a fishway 2, a flow channel A 3 and a flow channel B 4. The main body of the fishpond 1 is connected to the fishway 2. A channel 11, a protection assembly 5 and a pumping assembly 6 are arranged on the main body of the fishpond 1. The channel 11 is connected to the fishway 2. The fishway 2 is connected to the flow channel A 3. A gate assembly 7 is arranged on the fishway 2. The flow channel A 3 is connected to the flow channel B 4. The main body of the fishpond 1 is arranged at the water inlet of the flow channel A 3. The flow channel A 3 is arranged around the edge of the entire paddy field. The flow channel B 4 is arranged in the paddy field. The depth of the flow channel B 4 is 0.3 - 0.4 meters, and the width is 0.4 - 0.5 meters. The fish in the paddy field can sequentially enter the fishpond 13 through the flow channel B 4, the flow channel A 3 and the fishway 2.

[0027] Requirements for the planting density of rice in paddy fields: The planting density per mu is controlled at 14,000 - 16,000 holes. Rice must be planted on the outer water level line of the flow channel A3. The plant spacing is densely planted at intervals of 0.03 - 0.04 meters to achieve the purpose of preventing fish from swimming out and preventing enemies. The area of the fish pond structure 8 accounts for less than 10% of the total area of the paddy field. The position of the fish pond structure 8 is preferably in the middle of the field to avoid being too close to the ridge.

[0028] The gate assembly 7 includes a first support frame 71, a threaded seat 72, and a gate 73. The first support frame 71 is arranged on the fishway 2 and is connected to the top surface of the water retaining parts on both sides of the fishway 2. The threaded seat 72 is connected to the first support frame 71. A rotating handle 74 and a screw rod 75 are arranged on the threaded seat 72. The screw rod 75 penetrates through the rotating handle 74. The threaded seat 72 is rotatably connected to the rotating handle 74, and the threaded seat 72 is threadedly connected to the screw rod 75. One end of the screw rod 75 is provided with a connecting part 751, and no thread is provided on the connecting part 751. The connecting part 751 is connected to the gate 73 through a bearing seat 76, and the connecting part 751 is rotatably connected to the bearing seat 76. By rotating the rotating handle 74, under the action of the threaded connection between the threaded seat 72 and the screw rod 75, the screw rod 75 moves up and down, and drives the gate 73 to move up and down, achieving the effect of opening and closing the gate assembly 7.

[0029] Groove A21 and groove B22 are arranged in the fishway 2. The groove A21 is connected to the gate 73. A partition net 23 is arranged on the groove B22. The preparation materials of the partition net 23 include bamboo strips, wood, sand mesh, nylon net, and iron wire mesh. When installed, it is in an arc shape with the convex surface facing the paddy field direction to prevent fish from swimming out of the fish pond 13.

[0030] The protection assembly 5 includes a second support frame 51 and a heat insulation net 52. The top of the second support frame 51 is connected to the heat insulation net 52, and the bottom of the second support frame 51 is connected to the fish pond main body 1, which can prevent the fish pond 13 from being exposed to the sun and causing the water temperature to rise, affecting the growth of fish.

[0031] The bottom of the fish pond main body 1 is connected to the paddy field ground through a cushion layer 12. The material of the cushion layer 12 is concrete, and the area of the cushion layer 12 is larger than the area of the fish pond main body 1, which can increase the stability of the fish pond main body 1. The pumping assembly 6 includes a water pump 61. A pipeline A62 and a pipeline B63 are arranged on the water pump 61. The outlet end of the pipeline A62 is located in the fish pond 13, and the outlet end of the pipeline B63 is located on the paddy field, facilitating pumping the water in the fish pond 13 out of the paddy field or pumping the water on the paddy field into the fish pond 13. The fish pond 13 is located on the fish pond main body 1, and the fish pond main body 1 is communicated with the channel 11.

[0032] When the paddy field area is less than 1 mu, the flow channel B4 is arranged in a straight line in the paddy field. When the paddy field area is 1 - 2 mu, the flow channel B4 is arranged in a cross shape in the paddy field. When the paddy field area is 3 - 4 mu, the flow channel B4 is arranged in a grid shape in the paddy field. When the flow channel B4 is arranged in the paddy field, the area it divides should be evenly divided as much as possible. The setting of this flow channel B4 can provide sufficient swimming space for fish. When the paddy field area is 3 - 4 mu, two fish pond structures 8 can be arranged diagonally to avoid overcrowding of a single fish pond structure 8.

[0033] Fish have the habit of jumping, and some fish-eating birds will also peck the fish away on the ridge of the field; at the same time, there are often eels, field mice, and water snakes in the paddy field that dig holes through the ridge, causing water leakage and fish escape. Therefore, the ridge of the field needs to be heightened and widened, and stone strips or lime-sand soil slope protection should be used when necessary. The height of the ridge of the field depends on different regions and different types of paddy fields: in hilly areas, it should be 40 - 50 cm higher than the paddy field, in plain areas, it should be 50 - 70 cm higher than the paddy field, and the ridge of the field for winter fallow paddy fields and low-lying paddy fields in lake areas should be more than 80 cm higher than the paddy field, and the top width of the ridge of the field should be more than 50 cm.
