Description

Technical Field

[0001] The utility model relates to the field of aquaculture, in particular to a desalination device for aquaculture. Background Art

[0002] In order to meet market demand, many farmers need to carry out freshwater farming of shrimp. Since shrimp is a marine organism, the shrimp seedlings need to be desalinated and domesticated before freshwater farming. Generally, farms use temporary holding ponds to gradually dilute the pond water for desalination. After the shrimp seedlings are desalinated in the temporary holding ponds, they are picked up and placed in transfer boxes, and then the transfer boxes are transferred to various breeding ponds before the shrimp seedlings are poured out. This method requires multiple transfers of shrimp seedlings, which can easily cause the death of shrimp seedlings during the transfer process. Utility Model Content

[0003] In order to overcome the disadvantage that shrimp fry are easily killed during transfer, the utility model provides a desalination device for aquaculture which can automatically dump the shrimp fry into a breeding pond after the shrimp fry are desalinated, thereby reducing the number of transfers and the mortality rate of the shrimp fry.

[0005] In a preferred embodiment of the utility model, the driving assembly includes a winding wheel, which is rotatably connected to one side of the fixed water tank, and weights are slidably connected to the two guide columns close to the winding wheel. Two traction ropes are connected to the top of the weights, one end of the two traction ropes are passed around the winding wheel, and the two traction ropes are connected to one side of the clean water tank.

[0006] In a preferred embodiment of the utility model, the dumping mechanism includes a contact frame, the contact frame is fixedly connected to the inner bottom surface of the clean water tank, a roller is rotatably connected to the upper part of the contact frame, the contact frame passes through the bottom of the fixed water tank, a guide frame 1 is fixedly connected to each of the inner walls on both sides of the fixed water tank away from the notch, and both of the two guide frames 1 are provided with an arc groove, a guide frame 2 is fixedly connected to each of the inner walls on both sides of the fixed water tank away from the winding wheel, and both of the two guide frames 2 are provided with a vertical groove, a screen is slidably connected between the arc grooves of the two guide frames 1 and the vertical grooves of the two guide frames 2, and the bottom surface of the screen is in contact with the roller on the contact frame.

[0008] In a preferred embodiment of the present invention, a guide plate is provided on one side of the notch of the fixed water tank.

[0009] Compared with the prior art, the utility model has the following advantages: 1. After the water pump is started, the clean water in the clean water tank gradually decreases and the weight is reduced accordingly. Under the action of gravity, the weight gradually pulls the clean water tank upward through the traction rope. When the clean water tank is pulled upward, it drives the contact frame to move upward. The upward movement of the contact frame will drive the screen to slide upward in the fixed water tank. When the screen slides upward to the highest point in the groove of the guide frame 2, the side of the screen close to the guide frame 2 will no longer move upward. The continued upward movement of the contact frame will drive the screen to swing around the highest point in the groove of the guide frame 2, and all the desalinated shrimp seedlings will be dumped into the breeding pond at one time, which reduces the number of times the shrimp seedlings are transferred and reduces the mortality rate of the shrimp seedlings.

[0018] The driving assembly includes a winding wheel 6, which is rotatably connected to one side of the fixed water tank 3, and weights 7 are slidably connected to the two guide columns 2 close to the winding wheel 6. Two traction ropes 8 are connected to the top of the weights 7, and one end of the two traction ropes 8 are passed around the winding wheel 6, and the two traction ropes 8 are connected to one side of the clean water tank 4 through a hook.

[0019] The dumping mechanism includes a contact frame 9, the inner bottom surface of the clean water tank 4 is fixedly connected to the contact frame 9, the upper part of the contact frame 9 is rotatably connected to a roller, the contact frame 9 passes through the bottom of the fixed water tank 3, and the inner walls on both sides of the fixed water tank 3 away from the notch are respectively fixedly connected with a guide frame 10, and the two guide frames 10 are each provided with an arc groove, and the inner walls on both sides of the fixed water tank 3 away from the winding wheel 6 are respectively fixedly connected with a guide frame 2 11, and the two guide frames 2 11 are each provided with a vertical groove, and a screen 12 is slidably connected between the arc grooves of the two guide frames 10 and the vertical grooves of the two guide frames 2 11, and the bottom surface of the screen 12 is in contact with the roller on the contact frame 9.

[0020] The device is arranged near the breeding pond. Initially, there is an appropriate amount of clean water in the clean water tank 4, which is located below the fixed water tank 3. The weight block 7 is pulled up by the traction rope 8. Then the operator pours the shrimp seedlings and seawater into the fixed water tank 3, and then starts the pump 5 to gradually pump the clean water in the clean water tank 4 into the fixed water tank 3, so that the seawater in the fixed water tank 3 is mixed with the clean water and gradually desalinated. With the injection of clean water, the seawater and the clean water are mixed and gradually discharged from the overflow port. After the pump 5 is started, the clean water in the clean water tank 4 is gradually reduced, and the weight is reduced accordingly. Under the action of gravity, the weight block 7 gradually pulls the clean water tank 4 upwards through the traction rope 8, and the clean water tank 4 is When pulled upward, the contact frame 9 is driven to move upward, and the upward movement of the contact frame 9 will drive the screen 12 to slide upward in the fixed water tank 3. When the screen 12 slides upward to the highest point in the groove of the guide frame 11, the side of the screen 12 close to the guide frame 11 will no longer move upward. The contact frame 9 continues to move upward, which will drive the screen 12 to swing around the highest point in the groove of the guide frame 11, and all the shrimp seedlings that have been desalinated will be dumped into the breeding pond at one time, which reduces the number of times the shrimp seedlings are transferred and reduces the mortality rate of the shrimp seedlings. When the desalination of the shrimp seedlings is completed, the operator opens the water outlet pipe to drain all the water in the fixed water tank 3, and then closes the water outlet pipe for convenience next time use.

[0021] Embodiment 2: Based on embodiment 1, Figure 1-Figure 4 As shown, the opening and closing assembly includes a sliding frame 13, and the sliding frame 13 is slidably connected to the lower part of the clean water tank 4 near the traction rope 8. The sliding frame 13 contacts the circular hole at the bottom of the clean water tank 4, and one side of the sliding frame 13 contacts the inclined surface on the weight block 7. A reset spring 14 is provided between the sliding frame 13 and the clean water tank 4.

[0022] A guide plate 15 is welded on one side of the notch of the fixed water tank 3 .

[0023] When the tail end of the sliding frame 13 contacts the inclined surface of the weight block 7, the weight block 7 will push the sliding frame 13 to move, and the sliding frame 13 will no longer block the circular hole at the bottom of the fixed water tank 3. The speed at which the weight of the clean water in the clean water tank 4 decreases will be accelerated, and the upward speed of the clean water tank 4 will also become faster, thereby making the screen 12 swing faster, speeding up the dumping of the shrimp fry and preventing the death of the shrimp fry caused by too slow dumping.

[0024] When the shrimp fry after desalination is dumped, the guide plate 15 can guide the shrimp fry, so that the shrimp fry after desalination can flow into the breeding pond more accurately.
