Description

Technical Field

[0001] This utility model relates to the field of breeding boxes, and in particular to a ventilation and air exchange regulating device for black soldier fly breeding boxes. Background Technology

[0002] A breeding box is a closed or semi-closed container or equipment specifically designed for raising animals (such as insects, fish, reptiles, small mammals, etc.). Containers, as large-capacity breeding carriers, also fall under the extended application category of breeding boxes.

[0003] The ventilation and air exchange regulating device for black soldier fly breeding boxes is a device used to maintain air circulation and suitable environmental conditions inside the breeding box.

[0004] The existing ventilation and air exchange device for black soldier fly breeding boxes has the following shortcomings: During the daily use of the breeding box, it is necessary to continuously rely on ventilation and air exchange regulation devices to maintain a constant temperature inside the box and ensure a suitable growth environment for black soldier flies. In the existing technology, in order to prevent external debris from entering the box, most solutions will install a first dust screen at the air inlet. However, since these first dust screens are mostly fixed and cannot be easily disassembled, after long-term use, a large amount of dust, lint and external impurities will easily accumulate on the first dust screen. When too much foreign matter accumulates, it will not only block the air inlet channel, resulting in a decrease in air volume and affecting ventilation efficiency, but also reduce its interception and protection effect on debris. It may even cause problems such as temperature and humidity fluctuations and accumulation of harmful gases inside the box due to poor airflow, which will have an adverse impact on the stability of the breeding environment. Utility Model Content

[0005] This invention allows the insertion rod to disengage from the sealing ring, making it easy to remove the first dustproof net for cleaning, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a ventilation and air exchange regulating device for a black soldier fly breeding box, comprising a disassembly and assembly mechanism, an auxiliary mechanism fixedly installed on the inner wall of the disassembly and assembly mechanism, and a box cover hinged to the top of the disassembly and assembly mechanism; the disassembly and assembly mechanism includes a box body, and air ducts are fixedly connected to the outer walls of both the box body and the box cover, connecting blocks are fixedly connected to the outer walls of the air ducts, sliders are slidably connected to the inner walls of the connecting blocks, insert rods are fixedly connected to the outer walls of the sliders, sliding rods are fixedly connected to the inner walls of the connecting blocks, springs are sleeved on the outer walls of the sliding rods, sealing rings are slidably connected to the inner walls of the air ducts, a first dustproof net is fixedly connected to the inner walls of the sealing rings, and a fan is fixedly installed on the inner walls of the air ducts. Through the above components, the first dustproof net can be quickly disassembled, and the steps are simple.

[0007] Preferably, a second dustproof net is fixedly connected to the inner wall of each duct. The shaft end of the slide rod is fixedly connected to the outer wall of the slider. The outer wall of the insertion rod penetrates the inner wall where the sealing ring is provided. The shaft end of the slide rod is fixedly connected to the slider to ensure the guidance and stability of the slider when sliding in the connecting block, and to prevent the slider from deviating and causing the insertion rod to fail to accurately insert into the sealing ring. The outer wall of the insertion rod penetrates the inner wall of the sealing ring. Through the limiting effect of the insertion rod, the installation of the sealing ring and the first dustproof net in the duct is ensured to be firm, and the first dustproof net is prevented from loosening or shifting due to airflow impact during ventilation. The second dustproof net can prevent adult insects from touching the fan.

[0008] Preferably, one end of the spring is fixedly connected to the inner wall of the connecting block, and the other end of the spring is fixedly connected to the outer wall of the slider. The air duct includes two air outlets distributed along the top of the box cover and two air inlets distributed along the two sides of the bottom of the box. The air duct is divided into an air outlet at the top of the box cover and an air inlet at the bottom of the box, forming a bottom-in, top-out convection ventilation path to ensure that fresh air enters from the bottom and flows evenly through the breeding area, and exhaust gas is efficiently discharged from the top, reducing ventilation dead zones.

[0009] Preferably, the inner walls of the air ducts are all fixedly connected with semi-circular blocks, and the inner walls of the box are fixedly connected with grid plates. The grid plates inside the box provide a platform for black soldier flies to move around, preventing the insects from directly contacting the bottom of the box and causing local humidity and oxygen deficiency. At the same time, it facilitates the flow of ventilation air under the breeding substrate, improving environmental uniformity. Two semi-circular blocks are fixedly installed inside each air duct to partially block the air duct opening, thereby effectively reducing the frequency of air exchange between the inside of the box and the outside.

[0010] Preferably, temperature and humidity sensors and gas sensors are fixedly installed on the inner wall of the box. The temperature and humidity sensors and gas sensors can collect data on temperature, humidity, and concentration of harmful gases such as ammonia in the breeding box in real time, providing a scientific basis for ventilation regulation and avoiding breeding risks caused by blind adjustment of environmental parameters.

[0011] Preferably, a PLC controller is fixedly installed on the front of the housing, and support legs are fixedly connected to the bottom of the housing. Anti-slip pads are fixedly connected to the bottom of each support leg. The PLC controller is electrically connected to the components to control the opening and closing of the components.

[0012] Preferably, the auxiliary mechanism includes a fixed plate, and a constant temperature and humidity machine is fixedly installed at the bottom of the fixed plate. The constant temperature and humidity machine can actively perform heating, humidification or dehumidification operations based on the temperature and humidity data fed back by the sensor, to compensate for the temperature and humidity fluctuations that may be caused by simple ventilation, and to ensure the stability of environmental parameters inside the breeding box.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the quick disassembly and installation of the first dustproof net are achieved through the synergistic action of the connecting block, slider, insert rod, and spring. When impurities accumulate on the first dustproof net, simply push the slider to move the insert rod away from the sealing ring, and the first dustproof net can be easily removed for cleaning. This effectively solves the problems of difficult disassembly and inconvenient maintenance of traditional fixed first dustproof nets. In addition, the insert rod penetrates the inner wall of the sealing ring, and with the help of the elastic restoring force of the spring, it ensures that the first dustproof net remains firmly fixed during ventilation, avoiding loosening or displacement due to airflow impact. At the same time, the sealing ring further enhances the sealing between the air duct and the first dustproof net, preventing unfiltered air from entering the box and ensuring the safety and stability of equipment operation. Moreover, this structural design integrates a detachable dustproof net, standardized fixing components, and a bottom-in, top-out ventilation system, which has laid a good foundation for adapting to container-level aquaculture boxes and can effectively meet the maintenance needs of large-scale aquaculture scenarios.

[0014] 2. In this utility model, the air duct is divided into an outlet duct at the top of the box cover and an inlet duct at the bottom of the box, forming a bottom-in, top-out airflow circulation path. Fresh air enters from the bottom, flows through the breeding substrate, and exhaust gas is discharged from the top, effectively reducing ventilation dead zones and ensuring uniform air circulation in all areas of the box. In addition, a fan is installed on the inner wall of the air duct, and the speed can be adjusted by a PLC controller. With the partial blocking of the air outlet by the semi-circular block, the air exchange frequency during basic ventilation can be reduced (thereby reducing energy consumption), and the ventilation volume can be accelerated by the fan when the environment is abnormal, realizing on-demand ventilation and improving the intelligence and energy efficiency of the equipment operation.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Please see Figures 1-6 This utility model provides a technical solution: a ventilation and air exchange regulating device for a black soldier fly breeding box, including a disassembly and assembly mechanism 1, an auxiliary mechanism 2 fixedly installed on the inner wall of the disassembly and assembly mechanism 1, and a box cover 3 hinged to the top of the disassembly and assembly mechanism 1; the disassembly and assembly mechanism 1 includes a box body 101, and air ducts 104 are fixedly connected to the outer walls of both the box body 101 and the box cover 3, connecting blocks 113 are fixedly connected to the outer walls of the air ducts 104, and sliders 117 are slidably connected to the inner walls of the connecting blocks 113. The outer wall of the slider 117 is fixedly connected with the insertion rod 116, the inner wall of the connecting block 113 is fixedly connected with the slide rod 114, the outer wall of the slide rod 114 is fitted with the spring 115, the inner wall of the air duct 104 is slidably connected with the sealing ring 110, the inner wall of the sealing ring 110 is fixedly connected with the first dustproof net 109, and the inner wall of the air duct 104 is fixedly installed with the fan 112. With the above components, the first dustproof net 109 can be quickly disassembled, and the steps are simple.

[0020] like Figure 4 and Figure 5As shown, the inner wall of the air duct 104 is fixedly connected with a second dustproof net 118. The shaft end of the slide rod 114 is fixedly connected to the outer wall of the slider 117. The outer wall of the insertion rod 116 penetrates the inner wall of the sealing ring 110. The shaft end of the slide rod 114 is fixedly connected to the slider 117 to ensure the guidance and stability of the slider 117 when sliding in the connecting block 113, and to prevent the slider 117 from deviating and causing the insertion rod 116 to fail to accurately insert into the sealing ring 110. The outer wall of the insertion rod 116 penetrates the inner wall of the sealing ring 110. Through the limiting effect of the insertion rod 116, the installation of the sealing ring 110 and the first dustproof net 109 in the air duct 104 is ensured to be firm, and the first dustproof net 109 is prevented from loosening or shifting due to airflow impact during ventilation. The second dustproof net 118 can prevent adult insects from touching the fan 112.

[0021] like Figure 5 As shown, one end of the spring 115 is fixedly connected to the inner wall of the connecting block 113, and the other end of the spring 115 is fixedly connected to the outer wall of the slider 117. The air duct 104 includes two air outlet pipes distributed along the top of the box cover 3 and two air inlet pipes distributed along the two sides of the bottom of the box body 101. The air duct 104 is divided into an air outlet pipe at the top of the box cover 3 and an air inlet pipe at the bottom of the box body 101, forming a convection ventilation path with bottom inlet and top outlet, ensuring that fresh air enters from the bottom and flows evenly through the breeding area, and exhaust gas is efficiently discharged from the top, reducing ventilation dead corners.

[0022] like Figure 3 As shown, semi-circular blocks 111 are fixedly connected to the inner wall of each air duct 104, and a grid plate 106 is fixedly connected to the inner wall of the box 101. The grid plate 106 inside the box 101 provides a platform for black soldier flies to move around, preventing the insects from directly contacting the bottom of the box 101 and causing local humidity and oxygen deficiency. At the same time, it facilitates the airflow under the breeding substrate, improving the uniformity of the environment. Two semi-circular blocks 111 are fixedly installed inside each air duct 104 to partially block the air outlet of the air duct 104, thereby effectively reducing the frequency of air exchange between the inside of the box 101 and the outside.

[0023] like Figure 3 As shown, a temperature and humidity sensor 108 and a gas sensor 107 are fixedly installed on the inner wall of the box 101. The temperature and humidity sensor 108 and the gas sensor 107 can collect data on temperature, humidity, and concentration of harmful gases such as ammonia in the breeding box in real time, providing a scientific basis for ventilation regulation and avoiding breeding risks caused by blind adjustment of environmental parameters.

[0024] like Figure 2 As shown, a PLC controller 102 is fixedly installed on the front of the housing 101, and support legs 103 are fixedly connected to the bottom of the housing 101. Anti-slip pads 105 are fixedly connected to the bottom of the support legs 103. The PLC controller 102 is electrically connected to the components to control the opening and closing of the components.

[0025] like Figure 6 As shown, the auxiliary mechanism 2 includes a fixed plate 201, and a constant temperature and humidity machine 202 is fixedly installed at the bottom of the fixed plate 201. The constant temperature and humidity machine 202 can actively perform heating, humidification or dehumidification operations based on the temperature and humidity data fed back by the sensor, to compensate for the temperature and humidity fluctuations that may be caused by simple ventilation, and to ensure the stability of the environmental parameters inside the breeding box.

[0026] The device's operation and working principle: Ventilation is achieved through a duct 104 fixedly connected to the outer wall of the housing 101 and the cover 3. The duct 104 includes two outlet pipes at the top of the cover 3 and two inlet pipes on both sides of the bottom of the housing 101, forming a bottom-in, top-out convection ventilation path. Fresh air enters from the bottom inlet pipes, flows through the breeding area, and exhaust gas is discharged from the top outlet pipes, effectively reducing ventilation dead zones and ensuring uniform air circulation inside the housing. A fan 112 is fixedly installed on the inner wall of the duct 104, and its speed can be adjusted by the PLC controller 102 on the front of the housing 101. Combined with the partial obstruction of the air vents by the semi-circular block 111 fixed on the inner wall of the duct 104, this reduces the air exchange frequency during basic ventilation to reduce energy consumption, and also accelerates ventilation through the fan 112 in abnormal environmental conditions, achieving on-demand ventilation and improving the intelligence and energy efficiency of the equipment operation. A sealing ring 110 is slidably connected to the inner wall of the duct 104, and a first dustproof net 109 fixedly installed on the inner wall filters the air, preventing external debris from entering the housing. Inside, the fixing and disassembly of the first dustproof net 109 are accomplished collaboratively by the connecting block 113, the slider 117, the insert rod 116, and the spring 115. Under normal conditions, the elastic force of the spring 115 pushes the slider 117 to slide along the slide rod 114, causing the insert rod 116 to insert into the inner wall of the sealing ring 110 for fixing. Disassembly only requires pushing the slider 117 to disengage the insert rod 116 from the sealing ring 110, allowing the first dustproof net 109 to be removed for cleaning. The operation is convenient and easy to maintain. Furthermore, a temperature-controlled heating element is installed on the inner wall of the housing 101. Humidity sensor 108 and gas sensor 107 can collect data such as temperature, humidity and concentration of harmful gases in the chamber in real time and transmit the data to PLC controller 102. PLC controller 102 controls the start, stop and speed of fan 112 and the constant temperature and humidity machine 202 at the bottom of fixed plate 201 to perform heating, humidification or dehumidification operations according to preset parameters, thereby ensuring the stability of the environment inside the chamber. The grid plate 106 fixedly installed on the inner wall of the chamber 101 provides a platform for black soldier fly to move around and facilitates airflow.

[0027] The PLC controller 102, temperature and humidity sensor 108, gas sensor 107, and constant temperature and humidity machine 202 used in this application are all common conventional equipment on the market and are well known to those skilled in the art. In this application, the above equipment is used in a conventional manner without any improvement to its structure and function. As for their settings, installation, and connection methods, those skilled in the art can debug and operate them according to the corresponding product instruction manuals, so they will not be described in detail here.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
