Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture equipment, and in particular to a distributed water temperature control system. Background Art

[0002] The conventional water temperature control design scheme for factory-scale fish farms is to configure a water temperature control system based on the total demand of the fish farm, that is, to set up a water temperature control device at the front end of all the breeding ponds, and supply the water in the water temperature control device to each breeding pond through pipelines, so that it can be managed centrally. However, the disadvantages of this design are:

[0003] 1. If the water constant temperature equipment is damaged, it will directly affect the normal operation of the factory.

[0004] 2. When the fishery needs to expand its scale, the first thing to do is to increase the centralized area of ​​the constant temperature heat pump to determine whether there is enough space for expansion. Secondly, the construction uncertainty and difficulty of the expanded equipment are increased.

[0005] 3. The constant temperature heat pump of the water constant temperature system needs to be configured with power equipment according to the overall heating demand of the fishery, which requires the purchase of high-power and high-power heat pump equipment. However, the energy consumption of heat pump equipment increases geometrically with the increase of power. For example, the power consumption of a 10P heat pump will be greater than that of two 5P devices. This results in centralized heat pump equipment being more energy-consuming than distributed heat pump equipment. Summary of the invention

[0006] The purpose of the present invention is to provide a distributed water temperature control system to solve the above technical problems existing in the prior art.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A distributed water temperature control system provided by the present invention comprises a plurality of sets of constant temperature units for supplying constant temperature water to a plurality of sets of breeding ponds, each set of the constant temperature units being connected to each other through a branch pipe so that each set of the constant temperature units can provide constant temperature water to part or all of the breeding ponds; a switch valve is arranged on the branch pipe connecting two adjacent sets of the constant temperature units.

[0009] When a problem occurs in a water temperature control module of the distributed water temperature control system, other water temperature control modules will not affect the demand of the entire breeding unit, thus ensuring the normal operation of the fish farm.

[0010] As a further improvement of the present invention, the constant temperature unit includes a constant temperature heat pump system, a water circulation device, an inlet pipe and an outlet pipe. The water circulation device is connected to the breeding pond through the inlet pipe and the outlet pipe to circulate the breeding water; the inlet pipe at the outlet of the water circulation device is connected with a constant temperature inlet pipe and a constant temperature outlet pipe, and the ends of the constant temperature inlet pipe and the constant temperature outlet pipe are connected to the constant temperature heat pump system to heat part of the cold water flowing out of the water circulation device; a switch valve is provided on the inlet pipe between the constant temperature outlet pipe and the constant temperature inlet pipe to form constant temperature water after mixing high and low temperature water at the connection between the constant temperature outlet pipe and the inlet pipe; the two ends of the branch pipeline are respectively connected to the inlet pipes at the outlets of two adjacent sets of the water circulation equipment.

[0011] The modular distributed water temperature control system can adjust the number of running devices of the water temperature control system according to the usage of the breeding pond, thereby achieving the purpose of saving energy.

[0012] As a further improvement of the present invention, the branch pipeline is connected to the water inlet pipe located on the downstream side of the constant temperature water outlet pipe.

[0013] As a further improvement of the present invention, a temperature sensor is provided at the outlet of each set of the water circulation equipment.

[0014] As a further improvement of the present invention, each set of the water circulation equipment is connected to one or more sets of the water inlet pipes and the water outlet pipes to be connected to one or more sets of breeding ponds respectively.

[0015] As a further improvement of the present invention, a switch valve is provided on the water inlet pipe near the breeding pond.

[0016] As a further improvement of the present invention, switch valves are provided on the water outlet pipe near the breeding pond and near the water circulation equipment.

[0017] As a further improvement of the present invention, a switch valve is provided at the inlet of the water circulation equipment.

[0018] As a further improvement of the present invention, both the constant water inlet pipe and the constant temperature water outlet pipe are provided with switch valves.

[0019] As a further improvement of the present invention, the switch valve is an electric regulating valve.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The distributed water temperature control system provided by the present invention is configured with a set of water temperature constant temperature units according to a number of breeding ponds in a fish farm, and uses this constant temperature unit as a basic module for expansion and arrangement to form a distributed water temperature control system. The distributed water temperature control system can be allocated as needed according to the scale of the fish farm. All modular constant temperature units in the fish farm are internally connected to serve as an overall water temperature control system. When a certain set of water temperature control modules in the water temperature control system has a problem, other water temperature control modules will still not affect the constant temperature demand of the overall breeding unit. Moreover, in a modular arrangement, the overall system reserves a pipeline interface to facilitate the addition of water temperature control modules after the breeding units are added to the fish farm in the future.

[0022] The distributed water temperature control system provided by the present invention is a modular distributed water temperature control system, which splits a centralized large system into many controllable small systems, and solves the problem of scale expansion of factory water temperature control by means of divide and conquer. The distributed water temperature control system provided by the present invention is a high-availability control system, that is, the failure of any water thermostat will not cause the entire system to fail.

[0023] The present invention aims to solve the inherent defects of the centralized water thermostatic system in factories. By introducing a modular distributed water thermostatic system, it not only solves the problem of horizontal expansion of water thermostatic capacity during large-scale factory construction, but also solves the problem of single-point failure of the water thermostatic system. It provides aquaculture factories with a modular distributed water temperature control system that can be infinitely expanded and has high availability and energy-saving properties.

DETAILED DESCRIPTION

[0027] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0028] like Figure 1 As shown, the present invention provides a distributed water temperature control system, including multiple sets of constant temperature units for supplying constant temperature water to multiple sets of breeding ponds 100, each set of constant temperature units are connected through a branch pipe 200, so that each set of constant temperature units can provide constant temperature water to part or all of the breeding ponds; a switch valve is provided on the branch pipe connecting two adjacent sets of constant temperature units.

[0029] When a problem occurs in a water temperature control module of the distributed water temperature control system, other water temperature control modules will not affect the demand of the entire breeding unit, thus ensuring the normal operation of the fish farm.

[0030] Specifically, the constant temperature unit includes a constant temperature heat pump system 1, a water circulation device 2, an inlet pipe 3 and an outlet pipe 4. The water circulation device 2 is connected to the breeding pond 100 through the inlet pipe 3 and the outlet pipe 4 to circulate the breeding water; the inlet pipe 3 at the outlet of the water circulation device 2 is sequentially connected with a constant temperature inlet pipe 5 and a constant temperature outlet pipe 6, and the ends of the constant temperature inlet pipe 5 and the constant temperature outlet pipe 6 are connected to the constant temperature heat pump system 1 to heat part of the cold water flowing out of the water circulation device 2. A switch valve is provided on the inlet pipe 3 between the constant temperature outlet pipe 6 and the constant temperature inlet pipe 5 to mix high and low temperature water at the connection between the constant temperature outlet pipe 6 and the inlet pipe 3 to form constant temperature water to be supplied to the breeding pond 100; the two ends of the branch pipeline 200 are respectively connected to the inlet pipes 3 at the outlets of two adjacent sets of water circulation devices 2. The branch pipe 200 can connect two adjacent constant temperature units. Even if a constant temperature heat pump system 1 fails, the other constant temperature heat pump system 1 connected to it can still provide constant temperature water for the device.

[0031] Furthermore, the branch pipe 200 is connected to the water inlet pipe 3 located at the downstream side of the constant temperature water outlet pipe 6 .

[0032] A temperature sensor is provided at the outlet of each set of water circulation equipment 2.

[0033] The modular distributed water temperature control system can adjust the number of running devices of the water temperature control system according to the usage of the breeding pond, thereby achieving the purpose of saving energy.

[0034] Furthermore, each set of water circulation equipment 2 is connected to one or more sets of water inlet pipes 3 and water outlet pipes 4 to be connected to one or more sets of breeding ponds 100 respectively.

[0035] When multiple sets of culture ponds 100 are connected, multiple water inlet pipes 3 and multiple water outlet pipes 4 are arranged in parallel on the water circulation equipment 2 .

[0036] For ease of control, a switch valve is provided on the water inlet pipe 3 near the breeding pond 100 .

[0037] For the convenience of control, switch valves are provided on the water outlet pipe 4 near the breeding pond 100 and near the water circulation equipment 2 .

[0038] In order to facilitate control, a switch valve is provided at the inlet of the water circulation device 2 .

[0039] For the convenience of control, the constant temperature water inlet pipe 5 and the constant temperature water outlet pipe 6 are both provided with switch valves.

[0040] Furthermore, all the switch valves configured in the system are electric regulating valves.

[0041] Embodiment 1:

[0042] like Figure 1 As shown, in this embodiment, a distributed water temperature control system is provided, including three sets of constant temperature units, each set of constant temperature units is connected to a set of breeding ponds 100;

[0043] The three sets of constant temperature units all include a constant temperature heat pump system 1, a water circulation device 2, and connected constant temperature water inlet pipes 5, constant temperature water outlet pipes 6, water inlet pipes 3, water outlet pipes 4, and branch pipes 200. In the present embodiment, the constant temperature heat pump systems 1 in the three sets of constant temperature units are respectively connected to the water outlet pipes 3 at the outlets of the corresponding water circulation devices 2 through constant temperature water inlet pipes 5 and constant temperature water outlet pipes 6, and a first valve 10, a second valve 20, a fifth valve 50, a sixth valve 60, a ninth valve 90, and a tenth valve 100 are sequentially arranged on the three sets of constant temperature water inlet pipes 5 and constant temperature water outlet pipes 6; a third valve 30, a seventh valve 70, and an eleventh valve 110 are sequentially arranged on the branch pipe 100 corresponding to the positions of the three sets of constant temperature units. A fourth valve 40 is arranged on the water inlet pipe 3 between the constant temperature water inlet pipe 5 and the constant temperature water outlet pipe 6 of the first set of constant temperature units, an eighth valve 80 is arranged on the water inlet pipe 3 between the constant temperature water inlet pipe 5 and the constant temperature water outlet pipe 6 of the second set of constant temperature units, and a twelfth valve 120 is arranged on the water inlet pipe 3 between the constant temperature water inlet pipe 5 and the constant temperature water outlet pipe 6 of the third set of constant temperature units; a first temperature sensor A1 is arranged at the outlet of the water circulation equipment 2 of the first set of constant temperature units, a second temperature sensor A2 is arranged at the outlet of the water circulation equipment 2 of the second set of constant temperature units, and a third temperature sensor A3 is arranged at the outlet of the water circulation equipment 2 of the third set of constant temperature units.

[0044] During normal use, the first set of constant temperature units is taken as an example for specific description. The first valve 10, the second valve 20, and the fourth valve 40 are all opened, and the third valve 30 is closed. They are not connected to other breeding systems. Each constant temperature unit operates independently of each other. The water flows out of the integrated water circulation equipment 2. Between the fourth valve 40, the water flows through the constant temperature water inlet pipe 5 and the water inlet pipe 3 to the constant temperature heat pump system 1 and the fourth valve 40 respectively. The temperature value obtained by the first temperature sensor A1 is used to control the required opening of each valve through the electronic control system to control the water flow rate. The hot water heated by the heat pump enters the water inlet pipe after the fourth valve 40 through the constant temperature water outlet pipe 6 to mix with the unheated water to reach the required temperature and input into the breeding pond 100. Under normal circumstances, other units are the same as the above situation. When the thermostatic device of the first thermostatic unit fails, the first valve 10 and the second valve 20 are immediately closed, and the third valve 30 and the seventh valve 70 are opened, so that the pipes of the first thermostatic unit and the second thermostatic unit and the culture pool 100 are connected as one through the water inlet pipe 3 of the culture pool 100. The thermostatic device of the second thermostatic unit heats or cools the first culture unit (2 for 1), and the water flow is adjusted through the first temperature sensor A1 and the second temperature sensor A2 and the fourth valve 40, the fifth valve 50, the sixth valve 60 and the eighth valve 80, so that the final mixed water temperature meets the requirements of the fish pond. Or open the third valve 30, the seventh valve 70 and the eleventh valve 110 to detect the temperature through the first temperature sensor A1, the second temperature sensor A2 and the third temperature sensor A3, and the fourth valve 40, the fifth valve 50, the sixth valve 60, the eighth valve 80, the ninth valve 90, the tenth valve 100 and the twelfth valve 120 to adjust the water flow, and use the second set of constant temperature unit and the third set of constant temperature unit equipment to heat or cool the first set of breeding units (3 standby 1), so that the final mixed water temperature meets the requirements of the fish pond. The whole system can achieve N standby 1 or N standby 2 through the combination of switch valves.

[0045] The distributed water temperature control system provided by the present invention is configured with a set of water temperature constant temperature units according to a number of breeding ponds in a fish farm, and uses this constant temperature unit as a basic module for expansion and arrangement to form a distributed water temperature control system. The distributed water temperature control system can be allocated as needed according to the scale of the fish farm. All modular constant temperature units in the fish farm are internally connected to serve as an overall water temperature control system. When a certain set of water temperature control modules in the water temperature control system has a problem, other water temperature control modules will still not affect the constant temperature demand of the overall breeding unit. Moreover, in a modular arrangement, the overall system reserves a pipeline interface to facilitate the addition of water temperature control modules after the breeding units are added to the fish farm in the future.

[0046] The distributed water temperature control system provided by the present invention is a modular distributed water temperature control system, which splits a centralized large system into many controllable small systems, and solves the problem of scale expansion of factory water temperature control by means of divide and conquer. The distributed water temperature control system provided by the present invention is a high-availability control system, that is, the failure of any water thermostat will not cause the entire system to fail.

[0047] The present invention aims to solve the inherent defects of the centralized water thermostatic system in factories. By introducing a modular distributed water thermostatic system, it not only solves the problem of horizontal expansion of water thermostatic capacity during large-scale factory construction, but also solves the problem of single-point failure of the water thermostatic system. It provides aquaculture factories with a modular distributed water temperature control system that can be infinitely expanded and has high availability and energy-saving properties.

[0048] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
