Description

Technical Field

[0001] The invention belongs to the technical field of crab pond cooling, and in particular relates to a crab pond cooling and seed preservation device in high temperature seasons. Background Art

[0002] Crab farming is easily affected by high temperatures. Continuous high temperature weather will cause the temperature in the crab pond to rise, and the appetite of the crabs living in it will decrease, thus affecting the size of the adult crabs. At the same time, in a high temperature environment, the feed gathered at the bottom of the pond and the crab feces will decay faster, and the water body will be highly eutrophic, making crabs susceptible to diseases such as enteritis, resulting in a decrease in crab production in the crab pond. At the same time, high temperature also has a certain impact on the hatching of crab eggs.

[0003] In the prior art, the method for cooling the high-temperature crab pond is generally to put a large amount of ice cubes into the crab pond. This method will cause the water temperature near the ice cubes to drop rapidly. Crabs are more sensitive to changes in water temperature and are prone to stress. In addition, the cost of cooling with ice cubes is relatively high. Another method is to pass a large amount of well water into the crab pond for cooling. This method requires a large amount of water change in the crab pond, which is still easy to cause stress to crabs and is a large waste of water resources.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Embodiment 1:

[0029] Reference Figure 1-5 As shown, the present invention provides a crab pond cooling and seed preservation device in high temperature season, comprising: a shell 1, the shell 1 is arranged on one side of the crab pond 2, a condensing mechanism is arranged on one side of the bottom surface of the inner cavity of the shell 1, the condensing mechanism is connected with a heat exchange mechanism, the heat exchange mechanism is arranged on the other side of the bottom surface of the shell 1, the water inlet of the heat exchange mechanism is connected with the pool water in the crab pond 2 through a filtering mechanism, the water outlet of the heat exchange mechanism is connected with one end of a connecting pipe 3, the other end of the connecting pipe 3 is connected with one end of a water outlet main pipe 4, both sides of the bottom surface of the water outlet main pipe 4 are respectively fixedly connected to both sides of the crab pond 2 through connecting blocks 5, a plurality of slow-flow water outlet mechanisms and a plurality of spray mechanisms are arranged on the water outlet main pipe 4, and a sunshade mechanism is arranged on the top surface of any two adjacent slow-flow water outlet mechanisms.

[0030] The present invention arranges the shell 1 on one side of the crab pond 2, so as to facilitate cooling the crab pond 2. The condensing mechanism arranged in the shell 1 is used to continuously cool the internal refrigerant, and utilizes the heat exchange mechanism to transfer the low temperature of the refrigerant to the high temperature pool water in the heat exchange mechanism, thereby realizing cooling of the pool water in the heat exchange mechanism. In order to prevent the pool water entering the heat exchange mechanism from containing a large amount of impurities and causing blockage of the heat exchange mechanism, a filtering mechanism is arranged at the water inlet of the heat exchange mechanism to perform preliminary filtering on the pool water entering the heat exchange mechanism. The pool water cooled by the heat exchange mechanism flows into the water outlet main pipe 4 through the connecting pipe 3. The buffer arranged on the water outlet main pipe 4 The water outflow mechanism can realize the uniform introduction of cooling water into the crab pond 2, ensuring that the overall temperature of the crab pond 2 drops relatively evenly, and the situation where the temperature of a small area of ​​water changes greatly does not occur, avoiding the stress of the crabs in the crab pond 2 due to the rapid temperature change. A spray mechanism is also provided on the water outlet main pipe 4, and fine water mist is diffused in the air, which will be vaporized to reduce the heat in the air above the crab pond 2, avoiding the temperature increase of the crab pond 2 caused by the heat exchange between the high-temperature air and the water surface of the crab pond 2. The sunshade mechanism arranged between any two adjacent slow-flow water outflow mechanisms blocks the sunlight above the crab pond 2, avoiding the temperature increase of the crab pond 2 caused by direct sunlight. The present invention realizes the uniform introduction of the cooled low-temperature pool water into the crab pond 2 through the slow-flow water outflow mechanism, so that the overall temperature of the crab pond 2 is uniformly reduced, and the continuous increase of the temperature of the crab pond 2 is avoided by the spray mechanism and the sunshade mechanism.

[0031] A further optimized solution is provided, in which the heat exchange mechanism comprises a heat exchange tube 6, which is fixedly connected to one side of the bottom surface of the shell 1, and the inner cavity of the heat exchange tube 6 is respectively fixedly connected with an upper transverse plate 7 and a lower transverse plate 8, and the upper transverse plate 7 and the lower transverse plate 8 divide the inner cavity of the heat exchange tube 6 from top to bottom into a water outlet cavity 9, a heat exchange cavity 10 and a water inlet cavity 11, and a plurality of heat exchange tubes 12 are arranged in the heat exchange cavity 10, and the two ends of the plurality of heat exchange tubes 12 are respectively communicated with the through holes 13 opened on the upper transverse plate 7 and the through holes 13 opened on the lower transverse plate 8.

[0032] The upper horizontal plate 7 and the lower horizontal plate 8 arranged in the heat exchange tube 6 divide the inner cavity of the heat exchange tube 6 from top to bottom into a water outlet chamber 9, a heat exchange chamber 10 and a water inlet chamber 11, and the water outlet chamber 9 and the water inlet chamber 11 are interconnected through a plurality of heat exchange tubes 12. The heat exchange chamber 10 is used to cool down the high-temperature pool water. Since the high-temperature pool water in the water inlet chamber 11 needs to flow into the water outlet chamber 9 through a plurality of heat exchange tubes 12, the space in the heat exchange chamber 10 outside the heat exchange tubes 12 is filled with low-temperature condensed water. Due to the arrangement of the plurality of heat exchange tubes 12, the heat exchange area between the low-temperature condensed water and the high-temperature pool water is increased, thereby enhancing the heat exchange efficiency.

[0033] A further optimized solution is that the condensing mechanism includes a refrigerator 14, the inlet of the refrigerator 14 is connected to the top of the side wall of the heat exchange chamber 10 through a cooling water inlet pipe 15, the outlet of the refrigerator 14 is connected to the bottom of the side wall of the heat exchange chamber 10 through a cooling water outlet pipe 16, and a cooling circulation pump 17 is arranged on the cooling water outlet pipe 16.

[0034] The model of the refrigerator 14 is preferably: DX-20WT. The refrigeration circulation pump 17 can be used to pass the condensed water cooled in the refrigerator 14 from the bottom of the side wall of the heat exchange chamber 10 into the heat exchange chamber 10, and the condensed water after the heat exchange is completed can flow back to the refrigerator 14 from the top of the side wall of the heat exchange chamber 10 for re-cooling.

[0035] A further optimized solution is provided, in which the filtering mechanism includes a filtering connecting pipe 18, one end of which is connected to the side wall of the water inlet chamber 11, and the other end of the filtering connecting pipe 18 is connected to the water outlet of the filtering shell 19. A water pump 20 is arranged on the side of the filtering connecting pipe 18 close to the side wall of the water inlet chamber 11, and the water outlet of the filtering shell 19 is arranged on the top surface of the filtering shell 19. A water inlet of the filtering shell 19 is also arranged on the bottom surface of the side wall of the filtering shell 19, and the water inlet of the filtering shell 19 is connected to a porous cylinder 21. Two porous plates 22 are fixedly connected to the inner cavity of the filtering shell 19, and the two porous plates 22 divide the inner cavity of the filtering shell 19 into three storage bins 23 from top to bottom. The three storage bins 23 are respectively filled with filtering fillers 24, and the apertures of the filtering fillers 24 increase sequentially from top to bottom.

[0036] One end of the filter connecting pipe 18 is connected to the water outlet of the filter shell 19, and the other end is connected to the water inlet chamber 11. The water pump 20 arranged on the filter connecting pipe 18 can be used to pass the filtered pool water into the water inlet chamber 11, thereby ensuring the cleanliness of the inside of the heat exchange mechanism. The porous cylinder 21 arranged at the water inlet of the filter shell 19 prevents crabs from accidentally entering while ensuring the normal entry of pool water. The fillers of different particle sizes arranged in the three storage bins 23 gradually increase in particle size from top to bottom, thereby ensuring the filtering effect while avoiding blockage.

[0037] To further optimize the solution, the slow-flow water outlet mechanism includes a plurality of transverse water diversion pipes 25, one ends of which are respectively connected to the two side walls of the water outlet main pipe 4, and the other ends of which are set as closed ends. The bottom surfaces of the transverse water diversion pipes 25 are connected to the top surface of the water outlet pipe, and a spoiler is fixedly connected to the bottom surface of the water outlet pipe.

[0038] The transverse water diversion pipe 25 is arranged to divert the cold water in the main water outlet pipe, and the water outlet pipe connected to the bottom surface of the transverse water diversion pipe 25 passes the diverted cold water into the crab pond 2, and due to the arrangement of the flow-turbulating part, the outflowing cold water will be evenly diffused from the outlet pipe mouth.

[0039] A further optimized solution is that the spoiler includes a sleeve 26, the inner wall of the sleeve 26 is fixed to the bottom of the side wall of the water outlet pipe, connecting rods 27 are fixed on both sides of the bottom surface of the sleeve 26, the outer walls of the bearings 28 are fixed to the bottom surfaces of the opposite side walls of the two connecting rods 27, the inner wall of the bearing 28 is fixed to the bottom of the side wall of the rotating rod 29, and the top surface of the rotating rod 29 is fixed to the fan blades 30.

[0040] The provided sleeve 26 is used to fix the spoiler as a whole at the water outlet end of the water outlet pipe, and the provided connecting rod is used to fix the bearing 28 below the water outlet end. The inner wall of the bearing 28 is fixedly connected to the fan blade 30 through the rotating rod 29. When the water flow at the water outlet pipe impacts the fan blade 30, the water flow can drive the fan blade 30. At the same time, the rotation of the fan blade 30 also promotes the uniform diffusion of the cold water at the outlet of the water outlet pipe.

[0041] According to a further optimized solution, the spray mechanism includes a spray connecting pipe 31 , one end of which is connected to the top surface of the horizontal water distribution pipe 25 , and the other end of which is connected to the atomizing nozzle 32 .

[0042] One end of the spray connecting pipe 31 is connected to the water distribution pipe, and the other end is connected to the atomizing nozzle 32. Such a configuration enables part of the clean water in the horizontal water distribution pipe 25 to be atomized and sprayed out from the atomizing nozzle 32 after being filtered by the filtering mechanism. While vaporizing in the air, the temperature of the air above the crab pond 2 is reduced, thereby avoiding heat exchange between the hot air above the crab pond 2 and the water surface of the crab pond 2, thereby avoiding the increase in the temperature of the crab pond 2 to a certain extent.

[0043] A further optimized solution is that the shading mechanism includes a shading net 33, the sides of the shading net 33 are respectively fixedly connected to the side walls of two adjacent transverse water diversion pipes 25, the closed tubes of the two adjacent transverse water diversion pipes 25 are respectively fixedly connected to the ends of the connecting cross bar 34, and the other two side sides of the shading net 33 are respectively fixedly connected to the connecting cross bar 34 and the water outlet main pipe 4.

[0044] The function of the connecting cross bar 34 arranged at the closed end of the two horizontal water distribution pipes 25 of the ring bell is to fix the side of the sunshade net 33 together with the two adjacent connecting cross bars 34 and the water outlet main pipe 4, thereby reducing the area of ​​sunlight entering the pool water and avoiding a sharp increase in the temperature of the crab pond 2.

[0045] To further optimize the solution, a main water outlet valve 35 is provided on one side of the main water outlet pipe 4 close to the connecting pipe 3 .

[0046] The main water outlet valve 35 is arranged to control the flow rate in the main water outlet pipe 4, and further control the rate of cooling the pool water, which can be adjusted by the user according to his / her own needs.

[0047] According to a further optimization scheme, the refrigerator 14, the refrigeration circulation pump 17 and the water pump 20 are electrically connected to an external power source respectively.

[0048] Embodiment 2: The only difference between this embodiment and embodiment 1 is that in this embodiment, there can be multiple water outlet main pipes 4, thereby achieving coverage of crab ponds 2 of different areas.
