Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture equipment, in particular to a sewage barrier type shrimp fry culture pond. Background Art

[0002] In the process of shrimp fry breeding, there will be waste such as leftover bait, shrimp fry feces, shrimp fry molting, dead shrimp fry, etc. These wastes will sink to the bottom of the breeding pond. Among them, if the organic matter such as leftover bait and feces cannot be discharged in time, they will be decomposed into soluble substances such as ammonia and nitrite under the action of bacteria in the water. These substances are toxic to the growth of shrimp fry; and dead shrimp fry will transmit harmful microorganisms such as pathogens to live shrimp fry in the breeding pond, causing the spread of diseases. Therefore, it is particularly important to clean up the waste (residues) in the process of shrimp fry breeding.

[0003] Since shrimp fry are small and have poor resistance, the cleaning of shrimp fry breeding ponds is generally done by setting a filter or valve at the sewage outlet, and using the drainage method to use the water flow to carry the sewage out to achieve the effect of removing the sewage. Small particles of sewage can be effectively cleaned without affecting the growth of shrimp fry, but it is difficult to clean large residues such as shrimp shells and dead shrimps with a filter. Although the valve can remove large particles of sewage such as dead shrimp or molting, it is likely to cause the shrimp fry to escape from the valve or be carried away by the water flow. Therefore, it is of great significance to develop a breeding pond that can simultaneously remove the residual bait, feces, shrimp shells and dead shrimps in the shrimp fry breeding pond and prevent the escape of live shrimps.

DETAILED DESCRIPTION

[0017] 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.

[0018] like Figure 1-3As shown, a sewage discharge device for a shrimp fry breeding pond comprises a breeding pond body 1, which is square, and the bottom surface of the breeding pond body 1 is funnel-shaped to form a sewage accumulation area; a sewage outlet 5 is opened in the middle of the bottom surface of the breeding pond body 1, and the residual bait, shrimp fry, feces, shrimp fry shells and dead shrimp fry are concentrated at the sewage outlet 5, and the sewage outlet 5 is connected with a sewage pipe 7, and the sewage pipe 7 is connected with a live shrimp recovery pool 8 for recovering live shrimps that may be discharged with the dead shrimp fry, and a second valve 9 is provided on the right side wall of the live shrimp recovery pool 8. After the live shrimp recovery pool recovers the live shrimps, the second valve 9 is opened to flush away the residual bait, feces, shrimp fry shells, dead shrimp fry and other dirt; a bracket 13 is provided above the breeding pond body 1, and a traction device is provided on the bracket 13. The traction mechanism comprises two groups of traction ropes 121, a pulley block 122 and a reciprocating wheel 123. The traction rope 121 is wound around the reciprocating wheel 123. The pulley block 122 is fixedly mounted on the bracket 13. A torsion spring 15 is connected to the side of the reciprocating wheel 123 close to the bracket 13. The traction rope 121 passes through the pulley block 122 and is connected to the first baffle plate 4 and the second baffle plate 10 respectively. A first valve 6 is provided on the side of the sewage pipe 7 close to the sewage outlet 5. The dirt in the culture pond body 1 is cleared by opening the first valve 6. The first baffle plate 4 and the second baffle plate 10 are hinged on the opposite side walls of the culture pond body 1. The first baffle plate 4 and the second baffle plate 10 are hinged on the opposite side walls of the culture pond body 1. The plate and the second barrier plate are square, and the length of the first barrier plate and the second barrier plate is greater than half of the width of the breeding pond body, so the first barrier plate and the second barrier plate can horizontally block the shrimp fry breeding pond body when they are connected; the length of the second barrier plate 10 is longer than the length of the first barrier plate 4, and when the first barrier plate 4 and the second barrier plate 10 are pulled downward, the downward-inclined first barrier plate 4 can be pressed against the downward-inclined second barrier plate 10; the first barrier plate 4 and the second barrier plate 10 are respectively provided with a first limit block 3 and a second limit block 11 on the inner side wall of the breeding pond body, the position of the first limit block 3 is higher than the position of the second limit block 11, and the first limit block 3 is set The positions of block 3 and the second limit block 11 limit the maximum lifting height of the first baffle plate 4 and the second baffle plate 10. When the first baffle plate 4 and the second baffle plate 10 both reach the maximum lifting height, the first baffle plate 4 and the second baffle plate 10 are joined up and down at nearly 180 degrees, so that there is no gap at the joint of the first baffle plate 4 and the second baffle plate 10; the first baffle plate 4 and the second baffle plate 10 are provided with filtering holes 16, and small particles such as residual bait shrimp fry feces can pass through the filtering holes 16. The first baffle plate 4 and the second baffle plate 10 are connected to the traction mechanism on one side away from the inner wall of the breeding pond body 1, and the height of the first baffle plate 4 and the second baffle plate 10 can be stretched respectively by the traction mechanism.

[0019] Furthermore, rope binding rings 14 for fixing the traction rope 121 are provided at the bottom of both sides of the bracket 13 , and the rope binding rings 14 are used to bind the traction rope 121 when the traction rope 121 is not in use.

[0020] The working principle and use process of the utility model are as follows: when shrimp fry are normally cultured and shrimp fry shells and dead shrimp fry are not removed (the first valve 6 is in a closed state at this time), the first baffle plate 4 and the second baffle plate 10 are naturally turned down to be connected at a downward tilt. Since the second baffle plate 10 is longer than the first baffle plate 4, the first baffle plate 4 is pressed onto the second baffle plate 10, and there is no gap at the junction of the first baffle plate 4 and the second baffle plate 10. Therefore, large particles of dirt (shrimp fry shells, dead shrimp fry) will not fall from the junction of the first baffle plate 4 and the second baffle plate 10 to the dirt accumulation area, and most of the large particles of dirt (shrimp fry shells, dead shrimp fry) slide along the inclined surfaces of the first baffle plate 4 and the second baffle plate 10 and are concentrated near the junction of the first baffle plate 4 and the second baffle plate 10, while small particles of matter (residual bait, shrimp fry feces) will fall from the filter holes 16 on the first baffle plate 4 and the second baffle plate 10 to the dirt accumulation area. When it is necessary to remove the shrimp shells and dead shrimp (open the water inlet pipe to replenish the lost water in the breeding pond body), pull the traction ropes 121 on both sides at the same time, and the traction ropes 121 pull the first baffle plate 4 and the second baffle plate 10 to do up and down shaking motions at the same time (the shaking amplitude cannot be too large). The function of the first baffle plate and the second baffle plate shaking up and down at the same time is to drive away the live shrimp near the first baffle plate 4 and the second baffle plate 10, and keep them away from the first baffle plate 4 and the second baffle plate 10; on the other hand, it makes the shrimp shells and dead shrimp on the first baffle plate 4 slowly slide onto the second baffle plate 10, and then slowly lift the first baffle plate 4 , so that a gap appears between the first baffle plate 4 and the second baffle plate 10, and the second baffle plate 10 is continuously shaken up and down to make the large particles of dirt slide from the gap between the first baffle plate 4 and the second baffle plate 10 to the dirt accumulation area; after the large particles of dirt slide from the first baffle plate 4 and the second baffle plate 10 to the dirt accumulation area, the first baffle plate 4 and the second baffle plate 10 are simultaneously pulled up. Due to the presence of the first limit block 3 and the second limit block 11, the first baffle plate 4 and the second baffle plate 10 will eventually be limited to the maximum height. When the first baffle plate 4 and the second baffle plate 10 reach the maximum height, the two are in a state of nearly 180 degrees of vertical engagement, such as Figure 2 , 3 As shown, the first valve 6 is then opened to discharge the shrimp seed shells and dead shrimp seed in the dirt accumulation area out of the breeding pond body along with the water flow. In order to prevent the live shrimp seed that may be discharged along with the dead shrimp seed, the utility model is also provided with a live shrimp recovery pool 8 to recover the live shrimp seed.
