Description

Temperature control breeding device for early maturing river crabs

Technical Field

The utility model relates to a river crab breeds technical field, concretely relates to be used for river crab ripe accuse temperature breeding device in advance.

Background

The optimum growth temperature of the river crab is below 30 deg.C, preferably 19-25 deg.C, and above 38 deg.C, the river crab can not normally move. In the middle and lower parts of Yangtze river, the temperature is mostly above 35 ℃ in the daytime in summer, and in the 7-9 months, the days of the temperature appearing at 38 ℃ at least account for about 10% under the control of the high pressure of the subtropical zone, so that the growth speed of the river crabs in the period is obviously reduced.

Generally, the best season for river crabs is around the middle and last ten days of 10 months. However, the mid-autumn festival and the national celebration festival are two key festivals for the Chinese to consume crabs, but the two festivals often have insufficient crab supply or only have some crab supply which is on the market earlier but has poor taste. However, the optimal sale period is missed when the river crabs are normally mature, thereby causing no small economic loss to culturists. Although the river crabs can mature early by reducing the culture temperature of the river crabs, the temperature control cost is higher because the area of the culture water area of the river crabs is large, so that the culture cost of the river crabs is higher, and the profit space of farmers is lower.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects, the utility model aims to provide a temperature control breeding device for early maturing of river crabs.

The utility model discloses a accuse temperature breeding device for river crab is ripe in advance includes the cell body be provided with a plurality of crab cave in the cell body, at least some regions of the wall portion of crab cave are the fretwork, every be provided with at least one entry and at least one export on the crab cave, still including be used for right the temperature portion of controlling the temperature that adjusts in the cell body. The utility model provides a accuse temperature breeding device is through setting up accuse temperature portion, controls the temperature in the cell body from this to keep the optimum temperature that suitable crab grows in it, through setting up a plurality of crab caves in the cell body, therefore, effectively improved the quantity of river crab on the unit area, therefore, can reduce the region that needs accuse temperature by a wide margin, and then, effectively reduced the cost that river crab was bred.

Furthermore, the temperature control part comprises a heat exchanger, the heat exchanger is provided with a water inlet and a water outlet, at least one water flow channel is arranged in the heat exchanger, and two ends of the water flow channel are respectively communicated with the water inlet and the water outlet.

Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

The first embodiment is as follows:

see that figure 1 shows, the utility model discloses a accuse temperature breeding device for river crab is ripe in advance, including cell body 1 and accuse temperature portion, be provided with the crab cave in cell body 1 and bear seat 3, bear and be provided with a plurality of crab cave 31 on seat 3 at the crab cave, see that figure 2 is shown, the utility model discloses a crab cave 31 is hollow cylinder, is located the mutual parallel arrangement of crab cave 31 on the crab cave bears seat 3, and crab cave 31 is the direction setting parallel with the horizontal plane, and every crab cave bears seat 3 and sets up multilayer crab cave 31 on vertical, sets up multiseriate crab cave 31 on horizontal, therefore the river crab quantity that can perch on unit area obviously increases. A plurality of crab cave bearing seats 3 can be arranged in one tank body 1 according to requirements, and the arrangement positions of the crab cave bearing seats are adjusted, so that the crab cave bearing seats are convenient to apply.

At least a part of the wall of the crab cavity 31 is hollowed, the wall of the crab cavity 31 of the present invention is net-shaped, and preferably, the wall of the crab cavity 31 can be made of wire mesh or other materials. The wall of the crab pit 31 can be cylindrical with a plurality of water flow holes, so that each crab pit 31 can be ensured to be communicated with the water in the tank body 1, and each crab pit 31 is provided with an inlet and an outlet, which is convenient for the river crabs to enter and exit.

The utility model discloses a accuse temperature portion includes heat exchanger 21 and pond, the utility model discloses use the plate heat exchanger to explain as an example, it also can be for other heat exchangers, it is shown in referring to fig. 3-5, the utility model discloses a heat exchanger 21 has water inlet 211 and delivery port 212, is provided with a plurality of rivers passageway 213 in heat exchanger 21 inside, is provided with an intake antrum 214 that is linked together with water inlet 211 respectively at the both ends of rivers passageway 212, and the play water cavity 215 that is linked together with delivery port 212, therefore, the rivers that get into heat exchanger 21 through water inlet 211 can pass through heat exchanger 21 through each rivers passageway 212, after rivers that flow through rivers passageway 212 and the interior water of cell body 1 carry out the heat exchange, get into out water cavity 215 to discharge from delivery port 212. The heat exchanger 21 further comprises a shell 216, the heat exchanger 21 is connected with the tank body 1 through the shell 216 and is arranged in the area below the liquid level in the tank body 1, a first water pump is arranged between the water inlet 211 and the water tank, and a second water pump is arranged between the water outlet 212 and the water tank. Therefore, the water in the water tank can be quickly sucked into the water flow channel 213 of the heat exchanger 21 through the first water pump and be recirculated into the water tank by the second water pump, thereby enabling quick adjustment of the temperature of the water in the tank body 1 for cultivating the river crabs.

The temperature of the water in the basin is controlled below 30 c and ensures that the temperature remains relatively constant. Preferably, the utility model discloses a water source in the pond of accuse temperature portion is groundwater, and when water in the pond was low water, it can to extend the outlet of the mouth that draws water of first water pump and second water pump through the pipeline in low water layer. In order to avoid the pollution to the low water source, can use for the first time the utility model discloses a temperature control portion before utilize to mix with the water of sanitizer to wash clean repeatedly back again and with groundwater source intercommunication. Because the temperature of the underground water is kept at 10-20 ℃ throughout the year, the temperature of the circulating water flow in the heat exchanger 2 of the utility model is also kept at 10-20 ℃, and the cost for controlling the temperature of the river crabs is not obviously increased by the recycling of the underground water.

Example two:

the present embodiment is different from the first embodiment only in that the heat exchanger 21 is disposed on the outer side wall of the tank body 1, and as shown in fig. 6, the heat exchanger 21 is disposed outside the tank body 1, the cost of the housing 216 of the heat exchanger 21 can be reduced, and the heat exchanger 21 can be conveniently communicated with the water tank. When in use, a heat exchanger 21 can be arranged on at least one side wall of the outer side wall of the tank body 1 according to requirements.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered in the protection scope of the present invention.
