Description

Technical Field

[0001] This invention belongs to the field of biological research technology, and in particular relates to a light-based culture device for stored grain pests. Background Technology

[0002] In natural environments, light is a variable factor that cannot be ignored, and its impact on organisms has been increasingly recognized. It affects insect growth, development, reproductive capacity, and respiratory metabolism. Research on the effects of photoperiod on insect growth and development shows that photoperiod, light wavelength, and light intensity all significantly influence the predation ability of some insects. Other studies have indicated that different wavelengths, light intensities, and photoperiod durations affect the growth and development of insect eggs, larvae, pupae, and adults.

[0003] Storage insects (or stored grain pests), as an important part of the grain storage ecosystem, have always been a hot topic and a challenging area of ​​research. Numerous studies have shown that the duration, wavelength, and intensity of light exposure affect insect growth, development, reproduction, and behavior. However, most storage insects live in low-light or dark grain storage environments, and few studies have demonstrated the specific effects of light on them. While existing storage insect research facilities have mature temperature and humidity control systems such as air conditioning to provide suitable temperature and humidity conditions for insect cultivation, most existing storage insect light cultivation devices rely on natural light, complete darkness, or a single light source, making it impossible to precisely control the light conditions within the cultivation chamber.

[0004] The patent application CN114794025B, titled "An experimental device and method for low oxygen stress on stored grain insects," only studies the effects of different humidity or oxygen concentrations on the growth and development of stored grain pests. It does not mention that the effects of different light intensities on the growth and development of stored grain pests can be studied. Summary of the Invention

[0005] To address the problem that existing grain storage pest cultivation devices cannot study or control the effects of different light intensities on the growth, development, reproduction, and behavior of grain storage pests, this invention proposes a grain storage pest light cultivation device that can study the growth and development of grain storage pests under different light conditions.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A light-based cultivation device for stored grain pests includes a base, on which at least one cultivation unit is disposed. The cultivation unit includes a fan assembly and a cultivation component, wherein the fan assembly is located outside the cultivation component and is disposed adjacent to the cultivation component.

[0008] The fan assembly includes a fan housing and a fan, wherein the fan is disposed inside the fan housing.

[0009] The culture assembly includes a chamber, in which a first partition divides the chamber into a culture chamber and a light-illuminated chamber. The light-illuminated chamber is detachably equipped with a light-illuminating component and a light-adjusting device for adjusting the light intensity and duration of the light-illuminating component. The first partition is a light-transmitting plate. The base is hollow inside and has an air inlet. Each culture unit has an independent fan assembly, light-illuminated chamber, and culture chamber, which avoids cross-contamination between different culture units, thereby ensuring the accuracy of experimental results.

[0010] The bottom of the fan installation chamber is connected to the base, and the fan installation chamber is connected to the culture chamber. The fan is used to blow air into the culture chamber. The top of the culture chamber is provided with a culture chamber air outlet.

[0011] Using the above scheme, there will be no cross-contamination between each culture unit. The fan can blow air into the culture room to promote air circulation, thereby providing a suitable environment for the production of stored grain pests. The experimenter can adjust the light intensity and time as needed. The light-transmitting partition design also ensures that the light in the light chamber can be fully transmitted to the culture room, thus ensuring the accuracy of the study on the effects of light intensity and light time on the growth of stored grain pests.

[0012] Furthermore, an exhaust duct is provided above the culture chamber, which is connected to the culture chamber through the air outlet. A horizontally arranged middle partition inside the culture chamber divides it into an upper culture space and a lower culture space. The middle partition has ventilation openings, and each culture unit has two culture spaces. This allows for two sets of culture data under the same culture conditions, enabling cross-comparison and improving the efficiency and accuracy of the experiment. A culture chamber door is provided on one side of the culture chamber for easy operation, observation, and maintenance. The inner wall of the culture chamber door is coated with a reflective material to reflect the light emitted by the light-emitting components, making the lighting inside the culture chamber more uniform and providing better lighting conditions for pests.

[0013] Furthermore, the fan installation room is equipped with two fans, which blow air into the upper and lower culture spaces respectively, ensuring that both the upper and lower culture spaces have sufficient ventilation.

[0014] Furthermore, the base is equipped with an air duct, one end of which is connected to the air inlet of the base and the other end is connected to the fan housing. A water-holding box is detachably installed inside the base and is connected to the air duct. A heating resistor is installed inside the air duct, which can provide suitable humidity and temperature for the cultivation of stored grain pests.

[0015] Furthermore, the cultivation unit consists of four units arranged in a box, which is a cube, a straight cylinder, or a cuboid with a square horizontal cross-section.

[0016] Furthermore, when the box is a cube or a cuboid with a square horizontal cross-section, the horizontal cross-section of the light chamber is an isosceles right triangle, the horizontal cross-section of the culture chamber is an isosceles trapezoid, and the four light chambers are distributed around the vertical central axis of the box and form a light system with a square horizontal cross-section.

[0017] On the same horizontal cross section, the diagonal of the illumination system coincides with the diagonal of the box body, the upper base of the four culture chambers coincides with the hypotenuse of the four illumination chambers respectively, and there is a gap between two adjacent culture chambers. The gap is a fan placement chamber, and the horizontal cross section of the fan placement chamber is an isosceles triangle or a sector.

[0018] Furthermore, when the box is a straight cylinder, the four light chambers are distributed around the axis of the box and form a light system with a square or circular horizontal cross-section;

[0019] When the horizontal cross-section of the illumination system is square, the horizontal cross-section of the illumination chamber is an isosceles right triangle, and the horizontal cross-section of the culture chamber is an isosceles trapezoid with an arc base. On the same horizontal cross-section, the center of the illumination system coincides with the center of the box body, the base of the four culture chambers coincides with the hypotenuse of the four illumination chambers, and there is a gap between two adjacent culture chambers. The gap is a fan placement chamber, and the horizontal cross-section of the fan placement chamber is fan-shaped.

[0020] When the horizontal cross-section of the illumination system is circular, the horizontal cross-section of the illumination chamber is a sector with a central angle of 90°, and the horizontal cross-section of the culture chamber is a fan-shaped ring. On the same horizontal cross-section, the center of the illumination system coincides with the center of the box body, the inner arc of the four culture chambers coincides with the arc of the four illumination chambers respectively, and there is a gap between two adjacent culture chambers. The gap is a fan placement chamber, and the horizontal cross-section of the fan placement chamber is a sector.

[0021] Four culture units are arranged in a box. Whether the box is a cube, a straight cylinder, or a cuboid with a square cross-section, it can make effective use of space, making the entire device compact and allowing for various experiments or control experiments to be conducted in a limited space.

[0022] Furthermore, the illumination assembly includes a lamp panel, which is disposed in the illumination chamber and can be replaced with different lamp panels according to experimental needs. The light from the lamp panel provides illumination to the culture chamber through the first partition. The illumination adjustment device is disposed on the top of the lamp panel and extends out of the top of the illumination chamber.

[0023] Furthermore, the light adjustment device is a light adjustment knob, which includes a light intensity adjustment knob and a light duration adjustment knob. The light intensity adjustment knob adjusts the light intensity at arbitrary gradients within the range of 0 to 2000 Lx, and the light duration adjustment knob adjusts the light duration for any duration within the range of 0 to 24 h. The knob-type adjustment device is simple to adjust and convenient for studying the response of pests to light intensity and light duration.

[0024] Furthermore, both the upper and lower culture spaces are equipped with environmental monitors, and the culture chamber door is equipped with an environmental monitoring panel that is connected to the environmental monitors for real-time monitoring of the environmental conditions within the culture space; the environmental monitors include a temperature sensor, a humidity sensor, and a light sensor.

[0025] The beneficial effects of the present invention through the above technical solution are as follows:

[0026] 1. This invention includes a light-emitting component and a light-adjusting device for adjusting the light intensity and duration of the light-emitting component within a light-emitting chamber. The light-adjusting device can adjust the light intensity (0~2000 Lx) and the light duration (0~24 hours), facilitating the study of the effects of different light intensities and durations on stored grain pests. Furthermore, the light-emitting component in this invention is detachably installed within the light-emitting chamber, and by replacing the lamp panels with different light sources, it also provides the possibility of using light sources of different wavelengths to cultivate stored grain pests.

[0027] 2. The present invention sets up at least one culture unit, and each culture unit has two culture spaces, so that under the same culture conditions, there can be two sets of culture data, which can be compared with each other, thus improving the efficiency and accuracy of the experiment.

[0028] 3. This invention sets up four identical culture units arranged in a box, which can effectively utilize space and make the entire device compact. It can conduct multiple sets of control experiments simultaneously, thereby improving research efficiency. Furthermore, the arrangement of fan and lighting components ensures the uniformity of light and air circulation in the culture chamber. At the same time, the reflective material coated on the inner wall of the culture chamber door can further ensure the uniformity of light in the culture chamber.

[0029] 4. Environmental monitors are installed both inside and outside the culture room to monitor the temperature, humidity and light conditions inside the culture room in real time. Users can quickly obtain and record data through the environmental monitoring panel for easy adjustment. Attached Figure Description

[0041] like Figures 1 to 8 As shown, a light-based culture device for stored grain pests includes a base 1, on which at least one culture unit is provided. The culture unit includes a fan assembly and a culture component. The fan assembly is located outside the culture component and is arranged adjacent to the culture component to ensure the circulation of airflow in the culture chamber.

[0042] The fan assembly includes a fan housing 3 and a fan 10, wherein the fan 10 is disposed inside the fan housing 3;

[0043] The culture assembly includes a chamber, in which a first partition divides the chamber into a culture chamber 2 and a light-illuminating chamber 4. The light-illuminating chamber 4 contains a detachable light-illuminating component 12 and a light-adjusting device for adjusting the light intensity and duration of the light-illuminating component 12. The light-illuminating component 12 in the light-illuminating chamber 4 is detachable, allowing for the replacement of different light source tubes according to the required wavelength. The first partition is a light-transmitting plate 121, specifically transparent glass, to ensure that light rays smoothly enter the culture chamber 2. The base 1 is hollow inside, and an air inlet 7 is provided on the base 1.

[0044] The bottom of the fan installation chamber 3 is connected to the base 1, and the fan installation chamber 3 and the cultivation chamber 2 are connected. The fan installation chamber 3 and the cultivation chamber 2 share a side wall, and a fan opening is opened on the side wall. A filter screen is installed at the fan opening to prevent pests from leaving the cultivation chamber 2 through the fan opening. The fan 10 is used to blow air into the cultivation chamber 2. The top of the cultivation chamber 2 is provided with a cultivation chamber air outlet 13.

[0045] An exhaust duct is provided above the cultivation chamber 2. One end of the exhaust duct is connected to the air outlet, and the other end of the exhaust duct is connected to the cultivation chamber 2 through the cultivation chamber air outlet 13. The cultivation chamber 2 is divided into an upper cultivation space 201 and a lower cultivation space 202 with the same volume by a horizontally arranged middle partition 204. A middle partition ventilation opening 14 is provided on the middle partition 204 to realize air circulation between the upper and lower cultivation spaces. At the same time, a filter screen is installed at the ventilation opening 14 to prevent the stored grain pests in the upper cultivation space 201 and the lower cultivation space 202 from crossing.

[0046] A culture chamber door 205 is provided on one side of the culture chamber 2. The culture chamber door 205 is an aluminum alloy box door. To ensure the airtightness when the box door is closed, a magnetic strip and a rubber sealing strip can be installed on the inner edge of the culture chamber door 205. The culture chamber door 205 is rotatably connected to one side of the culture chamber 2. A common rotatable connection method can be used, such as rotatably connecting to the side plate shared by the fan installation chamber 3 and the culture chamber 2 through a rotating shaft. This will not be described in detail here. At the same time, the rotating shaft can also serve as an electrical circuit channel, with wiring running through it. The inner wall of the culture chamber door 205 is coated with a layer of reflective material, such as an aluminum plate or a metal plate with a reflective film attached, to reflect the light emitted by the light-emitting components, making the lighting in the culture chamber more uniform, reducing dead light angles, and improving the light utilization rate.

[0047] The fan installation chamber 3 is equipped with two fans 10, which blow air into the upper culture space 201 and the lower culture space 202 respectively. The two fans 10 can ensure that the upper and lower culture spaces obtain uniform airflow, avoid the problem of insufficient airflow caused by a single fan, and improve the uniformity of the culture environment. Accordingly, two fan outlets can be opened on the side plate shared by the fan installation chamber 3 and the culture chamber 2.

[0048] The base 1 is equipped with an air duct 16. One end of the air duct 16 is connected to the air inlet 7 of the base, and the other end is connected to the fan housing 3, thereby providing a stable air source for the fan housing 3 and ensuring that the fan can effectively circulate air. A water box 11 is detachably installed in the base 1 and is connected to the air duct 16. For example, it can be a pull-out sliding connection in the base 1 and can be manually pulled out to add water. By changing the saline solution of different concentrations in the water box 11, the humidity in the culture chamber 2 can be roughly adjusted. Under normal circumstances, the evaporation rate of water in the saline solution will slow down as the saline concentration increases. A heating resistor 19 is installed in the air duct 16. By changing the air temperature in the air duct 16, the air temperature in the culture chamber 2 can be changed.

[0049] like Figure 7 As shown, the airflow enters the air duct 16 through the air inlet 7 of the base, and is blown into the culture chamber 2 by the fan 10. The airflow in the two culture spaces then enters the exhaust channel through the ventilation port 14 of the middle partition and the air outlet 13 of the culture chamber, and is then discharged from the culture chamber 2. Finally, it is discharged from the box body through the air outlet connected to one end of the exhaust channel.

[0050] The base 1 includes a base plate, a base top cover plate 102 and a base side cover plate 101. The base top cover plate 102 is made of aluminum alloy and is used to support the box body. The base side cover plate 101 is located around the base 1, and the base air inlet 7 is located on the base side cover plate 101.

[0051] The illumination component 12 includes a lamp panel 122, which may be an LED lamp panel. The lamp panel 122 is disposed in the illumination chamber 4. The light from the lamp panel 122 provides illumination to the culture chamber 2 through the first partition. The illumination adjustment device is disposed on the top of the lamp panel 122 and extends out of the top of the illumination chamber 4.

[0052] The light adjustment device is a light adjustment knob 9, which includes a light intensity adjustment knob and a light duration adjustment knob. The light intensity adjustment knob can adjust the light intensity at any gradient within the range of 0~2000Lx, and the light duration adjustment knob can adjust the light duration at any length within the range of 0~24h. Through the setting of the knob, the light intensity and time can be conveniently adjusted according to experimental needs.

[0053] Both the upper culture space 201 and the lower culture space 202 are equipped with environmental monitors 15. The culture chamber door 205 is equipped with an environmental monitoring panel 5 that is connected to the environmental monitors 15 for displaying the temperature, humidity and light intensity inside the culture chamber 2. The environmental monitors 15 include a temperature sensor, a humidity sensor and a light sensor.

[0054] Furthermore, in this invention, the top of the illumination chamber 4 is also provided with an illumination circuit box 8, and the illumination component 12 is electrically connected to the illumination circuit box 8. The illumination circuit box 8 may also be provided with a USB interface for connecting to an external power source; for example Figure 8 As shown, the lighting circuit box 8 is connected to the main circuit and is electrically connected to the main circuit through connection point 17. It is equipped with a lighting circuit switch 18 to control the circuit's conduction and cutoff.

[0055] Specifically, such as Figure 8 As shown, the main circuit system includes a main circuit plug 21, a main circuit switch 20, a heating resistor 19, a water container 11, a fan 10, and a lighting circuit box 8 connected in sequence by lines; the heating resistor 19 is connected in series / parallel on the main circuit line, and the environmental monitor 15 is also electrically connected to the main circuit system and its signal is connected to the environmental monitoring panel 5.

[0056] In addition, the culture chamber 2 can also use a temperature and humidity control device in the prior art to control the temperature and humidity inside the chamber; or, while using the water box 11 and heating resistor 19 in this application to roughly ensure the humidity and temperature inside the culture chamber 2, a temperature and humidity control device in the prior art can be used. The present invention has no special limitation on this.

[0057] To further illustrate the present invention, the technical solutions provided by the present invention will be described in detail below with reference to the embodiments, but they should not be construed as limiting the scope of protection of the present invention.

[0058] Application Example 1:

[0059] In this embodiment, the cultivation unit consists of four units arranged in a box. Each fan placement chamber 3 is connected to only one cultivation chamber 2, thereby ensuring the independence of the experiments. The box is a cuboid with a square horizontal cross-section. The length, width, and height of the box are 100cm, 100cm, and 120cm, respectively, and quarter-rounded corners are provided on the four side edges of the box. The length, width, and height of the base 1 are 108cm, 108cm, and 20cm, respectively, and the length and height of the air inlet 7 on the base 1 are 8cm and 12cm, respectively.

[0060] The horizontal cross-section of the light chamber 4 is an isosceles right triangle, the horizontal cross-section of the culture chamber 2 is an isosceles trapezoid, and the horizontal cross-section of the fan placement chamber 3 is an axisymmetric polygon. The four light chambers 4 are distributed around the vertical central axis of the box and form a light system with a square horizontal cross-section. The length, width, and height of the light system are 20cm, 20cm, and 120cm, respectively.

[0061] On the same horizontal cross section, the diagonal of the illumination system coincides with the diagonal of the box body. The upper bottom of the four culture chambers 2 coincides with the hypotenuse of the four illumination chambers 4, which are the first partitions. There is a gap between two adjacent culture chambers 2. The gap is the fan placement chamber 3. The axis of symmetry of the fan placement chamber 3 coincides with the diagonal of the box body.

[0062] In this embodiment, the four fan mounting chambers 3 are vertically arranged at the four side ribs of the box body, and the horizontal cross-section of the fan mounting chamber 3 is fan-shaped. Specifically, in any horizontal cross-section, the fan-shaped area enclosed by the two endpoints of the rounded corners opened at the four side ribs of the box body and the four vertices of the lighting system is the fan mounting chamber 3. The trapezoidal area enclosed by the side plates of two adjacent fan mounting chambers 3 (i.e., the side plates shared by the fan mounting chamber 3 and the culture chamber 2), the first partition (i.e., the side plates adjacent to the light-emitting chamber 4 and the culture chamber), and the culture chamber door is the culture chamber 2. The side plates of the two adjacent light-emitting chambers are opaque, thereby ensuring that the light emitted by each light-emitting chamber 4 does not affect each other, and the space occupied by the four light-emitting chambers 4, the culture chamber 2, and the fan assembly is exactly the same.

[0063] Both the upper culture space 201 and the lower culture space 202 have a volume of 180L, which can hold multiple insect culture boxes. The specific calculation is as follows:

[0064] like Figure 3 and Figure 4 As shown, in a culture chamber with a trapezoidal cross-section, the upper base is a1, the lower base is a2, and the height is b. Therefore, the cross-sectional area of ​​the culture chamber is expressed as (a1+a2)·b / 2. The height of the culture chamber is h. Therefore, the internal volume of the culture chamber can be calculated using (a1+a2)·b / 2·h.

[0065] V=(a1+a2)·b / 2·h=(20+70)×34 / 2×115≈180000cm 3 =180L

[0066] V_total = 4 × V = 4 × 180L = 720L

[0067] As calculated above, each fan needs to supply approximately 90L of hot air to each layer of the culture space in a single culture chamber. To shorten the ventilation time, the AGIO-12 model fan is selected. The specific parameters of this model fan are as follows:

[0068] Fan dimensions: 120×120×25mm;

[0069] Fan speed: 1200±10% RPM;

[0070] Fan current: 0.28A;

[0071] Fan bearings: Long Life Bearing;

[0072] Fan air volume: 39.86 CFM (MAX);

[0073] Fan air pressure: 0.65mmH2O (MAX).

[0074] Based on the above parameters, the ventilation volume of this fan is approximately 18.8L per second, so it only takes about 5 seconds to fill the entire culture chamber with hot air.

[0075] Application Example 2:

[0076] The technical solution in this embodiment is basically the same as that in application embodiment one, except that:

[0077] like Figures 9-10 As shown, in this embodiment, the box is a straight cylinder, and the four light chambers 4 are distributed around the axis of the box, forming a light system with a horizontal cross-section of square or circle;

[0078] When the horizontal cross-section of the illumination system is square, the horizontal cross-section of the illumination chamber 4 is an isosceles right triangle, and the horizontal cross-section of the culture chamber 2 is an isosceles trapezoid with an arc base. On the same horizontal cross-section, the center of the illumination system coincides with the center of the box body, the upper base of the four culture chambers 2 coincides with the hypotenuse of the four illumination chambers 4, and there is a gap between two adjacent culture chambers 2. The gap is the fan mounting chamber 3, and the horizontal cross-section of the fan mounting chamber 3 is fan-shaped. The axis of symmetry of the fan mounting chamber 3 coincides with the extension line of the joint of the two illumination chambers 4.

[0079] When the horizontal cross-section of the illumination system is circular, the horizontal cross-section of the illumination chamber 4 is a sector with a central angle of 90°, and the horizontal cross-section of the culture chamber 2 is a fan-shaped ring. On the same horizontal cross-section, the center of the illumination system coincides with the center of the box body. The inner arcs of the four culture chambers 2 coincide with the arcs of the four illumination chambers 4 respectively. There is a gap between two adjacent culture chambers 2. The gap is the fan mounting chamber 3. The horizontal cross-section of the fan mounting chamber 3 is sector-shaped, and the axis of symmetry of the fan mounting chamber 3 coincides with the extension line of the joint of the two illumination chambers 4.

[0080] In this embodiment, the four fan installation chambers 3 are respectively vertically arranged on the side of the box body. Specifically, on any horizontal section, the fan-shaped area enclosed by the lines connecting the two symmetrical points on the box body along the extension line of the joint of the two light-illuminating chambers 4 and the four vertices of the splicing point of the light-illuminating system is the fan installation chamber 3. The isosceles trapezoidal or fan-shaped annular area with an arc bottom formed by the side plates of two adjacent fan installation chambers 3 (i.e. the side plates shared by the fan installation chambers 3 and the culture chamber), the first partition (i.e. the side plates shared by the light-illuminating chamber 4 and the culture chamber), and the culture chamber door is the culture chamber 2.

[0081] Based on the above structure, this invention designs a storage pest device that can control light intensity and duration, in addition to existing devices. This addresses the problem of imperfect lighting systems or difficulty in precisely controlling lighting conditions within the storage pest cultivation process in existing technologies. To adapt to this lighting system, the layout and structure of the cultivation chamber have been improved. This device can then be used to explore suitable lighting conditions for the growth and development of storage pests at various stages, or to set appropriate lighting conditions for cultivating storage pests. Furthermore, the temperature, humidity, and light control system of this invention is simple to operate, the overall size of the device is small, and it is divided into four independent cultivation chambers, each with a double-layered cultivation area, thus improving the cultivation efficiency of storage pests.

[0082] In this embodiment of the invention, the entire lighting system is detachable, which makes it possible to use light sources of different wavelengths to cultivate stored grain pests. The door of the cultivation chamber is coated with reflective material so that the light can be evenly distributed in the cultivation chamber and can greatly improve the space utilization of the insect cultivation chamber.

[0083] The embodiments of the present invention are characterized by low cost, reasonable space utilization, complete functions, and strong practicality, and can meet the current research needs of various grain storage pests.

[0084] All aspects not detailed in this invention are conventional technical means known to those skilled in the art.

[0085] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
