Description

Electronic retractable air conditioning system for livestock {AIR CONDITIONING SYSTEM FOR LIVESTOCK FARMS WITH ELECTRONIC OPENING AND CLOSING}

The present invention relates to an electronically retractable air conditioning system for livestock, and more particularly, to an air conditioning system that can selectively or locally control temperature in a livestock and exhaust harmful gases for breeding temperature-sensitive livestock such as pigs. it's about

In livestock facilities where livestock such as pigs are raised, various harmful gases and heat of fermentation are inevitably generated due to fermentation of livestock manure or oxidation and reduction of various organic substances.

At this time, if the generated harmful gas or fermentation heat is not properly treated and remains, it will have a negative effect on the growth of pigs sensitive to temperature or the surrounding environment, as well as adversely affect the working environment of the worker. In most cases, livestock facilities are operated without a large fan for ventilation or air conditioning facilities for ventilation and temperature control inside the livestock facility, resulting in serious environmental problems such as death or disease of livestock.

However, in recent years, as a solution in recognition of this problem, Korean Patent Application Laid-Open No. 2006-0132074 (published on December 21, 2006) presents a technology for a livestock ventilation and air conditioning system.

According to this prior art, the gas generated when the manure of livestock decays and various polluted air generated by the respiration of the livestock are efficiently separated and discharged using the specific gravity difference, and purified and harmonized fresh air is provided into the livestock house. There is this.

However, this prior art has to be installed at the level of remodeling the entire structure of the livestock facility because it is difficult to simply install it in the existing livestock facility, which has structurally weak infrastructure, and it is distributed even if contamination occurs only in some areas, not the entire livestock facility. There is a problem in that it is difficult to use the system efficiently because the intake operation or the provision of harmonized air is inevitably made for the entire livestock facility in which the device or the suction fan is installed.

Therefore, it is necessary to research and develop an integrated livestock management system that minimizes facility changes to the livestock facility structure and is easily installed so that stable temperature control and ventilation in the livestock facility can be performed locally as well as the entire livestock house.

The electronically retractable air conditioning system 100 for livestock according to the present invention can accurately control the amount of air conditioned and control the temperature and pollution level for the entire livestock, as well as local temperature control and harmful effects on the imbalance point in the livestock. This invention was devised to allow the gas to be exhausted quickly, thereby improving the efficiency of thermal management in the livestock house, and animal welfare and safety related to the breeding environment can be promoted together.

In order to implement the above-described functions or actions in detail, the electronically retractable air conditioning system 100 for livestock according to the present invention, as shown in FIGS. ), the first branch 160 and the second branch in the configuration of the embodiment as shown in Fig. 6 and an embodiment including the opening and closing operation unit 130, the sensor unit 140 and the control unit 150, etc. (170) and the like may be configured as a modified example.

Hereinafter, each of the above-described components will be described in detail.

First, the air conditioner 110 removes impurities or moisture from the air sucked from the outside, heats or cools the air to a set temperature, and then sends the conditioned air to the duct part 120 to be described later or harmful in the livestock house. It is a component that performs a series of operations of inhaling and discharging gas and the like.

The air conditioner 110 is composed of a heater (not shown) as a heating device, a cooler (not shown), and a blower fan (not shown) for making air flow, installed on one side of the livestock, and a control unit 150 to be described later. According to the set control operation of the system, air conditioned at a predetermined temperature is sent out or harmful gases in the livestock are sucked in and discharged.

At this time, the flow of air for sending the conditioned air or for discharging harmful gases in the livestock house may be made by the above-described forward and reverse rotation of the blower fan.

The duct part 120 is a tubular-shaped component that is long installed in the barn in a state of being in communication with the air conditioning device 110, and a plurality of tuyeres 122 spaced apart from each other pointing to different points in the barn along the longitudinal direction thereof. ) is formed to discharge the air provided from the air conditioner 110 to each directing point.

The duct part 120 according to the embodiment and modification of the present invention may be made of a rectangular tube as shown in FIGS. 1 and 6, or may be formed of a cylindrical, polygonal, or the like tube, as shown in FIG.

At this time, the shape of the air outlet 122 may be a circular shape as shown, or a polygonal shape such as a quadrangle as shown.

The opening/closing operation unit 130 accurately controls the amount of air discharged from the tuyeres 122 for precise temperature control at the temperature imbalance point in the livestock, while the opening/closing operation for the tuyeres 122 affects livestock breeding. It is a component designed to be achieved without any mechanical operating noise.

In order to implement the above functions, the opening/closing operation unit 130 according to the embodiment and modification of the present invention uses a shape memory body 136 that is continuously deformed by heating and cooling according to the application of control power. Thus, the air outlet 122 is opened and closed.

That is, the opening/closing operation unit 130, as shown in FIG. 3, is composed of a blocking plate 132, an opening/closing frame 134, and a shape memory body 136, and the conditioned air discharged from the air outlet 122. to precisely control the amount of output.

Here, the blocking plate 132 is a component made of a plate shape that can cover the air outlet 122, and is lightweight so that it can move quickly and smoothly according to the bending deformation of the shape memory body 136, which is a power source, as will be described later. It is preferable to make it from a material.

The opening/closing frame 134 is a component installed in a ring shape along the circumference of the air outlet 122 to firmly support the above-described blocking plate 132 without shaking and guide the opening and closing operation of the blocking plate 132. A slit groove 134a may be formed around the frame 134 to allow the blocking plate 132 to be inserted into the opening/closing frame 134 or separated outward in the lateral direction.

When the blocking plate 132 is completely inserted into the slit groove 134a, the above-described air outlet 122 is closed to block the air conditioned air, and the blocking plate 132 is completely separated from the slit groove 134a. , the tuyere 122 is open to the front, so that the amount of air conditioned air is discharged to the maximum.

The shape memory body 136 is a component provided to provide a noiseless and stable driving force to the blocking plate 132 that performs the opening/closing operation for the air outlet 122, and is not unfolded by heating and cooling by the application of control power. Alternatively, it can be manufactured using a shape memory alloy (SMA) that is flexible.

The shape memory body 136 according to the embodiment and modification of the present invention is a two-way shape memory effect, that is, it is forcibly stretched (or bent) while expressing rigidity at high temperature (heating), which is an austenite state, and martensite. It is desirable to produce rigidity again at low temperature (when cooled) and to have the property of forcibly bending (or unfolding). .

As shown in FIG. 3 , the shape memory body 136 of the two-way shape memory may have a bar shape having one end coupled to one side of the opening/closing frame 134 and the other end coupled to the blocking plate 132 . .

At this time, when the shape memory body 136, which is itself a resistor, is selectively applied with control power in a predetermined range from the control unit 150 through a pair of lead wires 137, it is forcibly heated due to resistance heating by energization. By performing the unfolding operation, the above-described blocking plate 132 is separated from the slit groove 134a and the air outlet 122 is opened.

Conversely, when the shape memory body 136 does not receive control power from the control unit 150 through the pair of lead wires 137 (power cut off), it cools and performs a forced bending operation, so that the slit groove 134a) By inserting the above-described blocking plate 132 into the inside, the air outlet 122 is closed.

Here, the shape memory body 136 is stretched or bent as necessary through the control operation of the control unit 150 to intermittently increase and decrease the control power applied through the lead wire 137, thereby opening the air outlet 122. Alternatively, the degree of occlusion (ie, air delivery amount) can be freely adjusted.

On the other hand, unlike the above, the shape memory body 136 has a one-way shape memory effect, that is, it expresses rigidity at a high temperature (when heated) in an austenite state, and is forcibly stretched, and deforms freely at a low temperature (when cooled) in a martensitic state (when cooled). It may be manufactured to have a length elongation) characteristic. However, in this case, when the martensite state, an elastic member (not shown) forcing the shape memory body 136 to be in a bent state may be additionally installed.

As described above, as the shape memory body 136 is applied as a power source for moving the blocking plate 132, the amount of air discharged from the tuyere 122 is precisely controlled, while the opening and closing operation for the tuyere 122 is for livestock breeding. It can be implemented without noise without mechanical operating noise affecting the
