Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of biological technology equipment, specifically relates to an electric stimulation device capable of uniformly relieving silkworm frame rearing eggs diapause. BACKGROUND

[0002] As egg diapause insects, silkworms (Bombyx mori) are widely used in silkworm production, and the application of diapausing silkworm varieties makes it necessary to relieve silkworm egg diapause and achieve artificial hatching as the key foundation for multiple batches of silkworm breeding. Corona discharge is a local discharge phenomenon that occurs when the curvature radius of the electrode surface is small, resulting in a strong electric field near the electrode surface under atmospheric pressure or higher pressure. In this process, a corona layer is formed near the electrode, with a high electric field strength, causing intense ionization and excitation, as well as the production of ozone, nitrogen oxide and other substances. Numerous studies have shown that the corona discharge method for relieving silkworm egg diapause has many advantages, such as no environmental pollution, easy operation, low labor intensity, and easy mechanization and intelligentization, and its effect is comparable to the current production of acid immersion technology.

[0003] The applicant's previous patent application discloses an electric stimulation device for relieving silkworm egg diapause, with the authorization announcement number CN216567810U. The device places silkworm eggs on a metal electrode plate and uses a high-voltage static generator to generate a high-voltage electric field to produce corona discharge, thereby stimulating silkworm eggs and relieving silkworm egg diapause to achieve artificial hatching. However, during use, it was found that the high-voltage power supply of the device was limited by power, and when the number of parallel discharge needles increased, the voltage could not be raised, for example: when 16 discharge needles were connected, the output voltage would be lower than 10KV, which could not meet the electric stimulation conditions required by silkworm eggs; if the number of discharge needles was too small, the effective electric stimulation area would be reduced, resulting in a very limited number of silkworm eggs that the device could handle, and it could not complete the diapause of all silkworm eggs in one or more moth circles in the frame rearing eggs at one time. However, the current scientific research on silkworms, variety resource protection and original seed production mainly use frame rearing eggs to prepare silkworm eggs.

[0004] Therefore, there is an urgent need for an electric stimulation device capable of uniformly relieving silkworm frame rearing egg diapause. SUMMARY

[0005] The utility model aims to solve at least the above-mentioned defects and provide the advantages to be explained later.

[0006] Another object of the utility model is to design an electric stimulation device capable of uniformly relieving silkworm frame rearing egg diapause and suitable for frame rearing eggs.

[0007] In order to realize these objects and other advantages of the present application, the electric stimulation device for uniformly releasing the diapause of the domestic silkworm egg is provided, comprising: a high-voltage static electricity generation and output end and a domestic silkworm egg processing structure connected with the high-voltage static electricity generation and output end.

[0013] In addition, the conical discharge structure is designed and explored according to the frame type silkworm egg, and a plurality of moth circle eggs can be processed at one time under smaller power, which greatly improves the efficiency of releasing the diapause of the silkworm egg and is safe and energy-saving.

[0014] In addition, the discharge structure is a wire electrode, which can effectively prevent the mutual interference of the electric fields between different discharge wires, make the whole electric field discharge uniform, and ensure that the practical hatching rate of the treated silkworm egg single moth circle is above 96%.

[0015] Moreover, specifically, the thin wire is a copper thin wire; using the copper thin wire as the discharge structure, the service life of the copper wire electrode is longer than that of the common needle electrode, so that the replacement frequency of the discharge end can be reduced. The lower end of the discharge is changed from a needle electrode to a wire electrode, so that the corona discharge is normal under the condition that the output voltage of 10kV commonly used for removing the diapause of silkworm eggs is removed, and the ion wind action area is expanded and the number of treated silkworm eggs is increased.

[0020] Preferably, a through hole is formed in the middle of the insulating cross rod, and the middle segment of the discharge structure penetrates through the through hole and extends downward.

[0021] In the above scheme, the structure of the discharge structure and the insulating cross rod is improved, so that the installation of the discharge structure is more stable, and the middle segment can smoothly pass through the insulating cross rod, ensuring stable transmission of electrical signals, reducing signal interference, and improving the effect of electric stimulation.

By determining the positional relationship between the end of the thin wire and the metal plate, it is ensured that the electric stimulation can effectively act on the silkworm eggs, and the non-uniform electric stimulation or the ineffective stimulation of the silkworm eggs due to improper position is avoided.

[0040] Figure 1 An implementation form of the utility model is shown, the electric stimulation device capable of uniformly removing diapause of silkworm frame rearing eggs, comprising: high-voltage electrostatic generation and output end 1 and silkworm egg processing structure 2 connected with the high-voltage electrostatic generation and output end 1.

[0042] The silkworm processing structure 2 comprises an insulating support plate 21, a metal electrode plate 22, an insulating support frame 23 and a discharge structure 24. The metal electrode plate 22 is connected above the insulating support plate 21. The insulating support frame 23 comprises two vertical support rods 231 and an insulating cross rod 232 vertically connected between the vertical support rods 231. The two vertical support rods 231 are vertically connected above the insulating support plate 21. The insulating cross rod 232 is connected to the upper end of the vertical support rod 231. The discharge structure 24 comprises an upper end 241, a middle section 242 and a lower end 243. The upper end 241 is connected to the high-voltage electrostatic output terminal. The top of the middle section 242 is connected to the upper end 241. The lower end 243 is connected to the bottom of the middle section 242.

[0043] The metal electrode plate 21 is located between the two vertical support rods 231. The upper end 241, the middle section 242 and the lower end 243 are electrically connected. The lower end 243 is composed of a plurality of fine lines arranged in a conical shape.

[0044] In use, the silkworm frame seedling eggs are placed on the metal electrode plate. The high-voltage electrostatic generator is turned on. The output voltage and time are adjusted through the control panel. The electric stimulation generated by the discharge structure uniformly acts on the silkworm eggs, thereby achieving the purpose of relieving the diapause of the silkworm eggs. The operator can monitor the voltage data in real time through the display screen to ensure the normal operation of the device.

[0045] Further, the input voltage of the high-voltage electrostatic generator is 220 V, and the output current is 0-1.5 mA.

[0046] In the implementation process of the embodiment, in order to ensure that the input voltage of the high-voltage electrostatic generator is 220 V, it can be directly connected to the 220 V alternating current power socket commonly used in families or industries. In the internal circuit design of the high-voltage electrostatic generator, a suitable transformer and rectifier circuit are used to convert the input 220 V alternating current into a stable direct current voltage required by the device, and the output current is adjusted within the range of 0-1.5 mA through a current adjusting circuit. At the same time, overcurrent protection and overvoltage protection devices are arranged in the circuit. When the output current or voltage exceeds the set range, the circuit is automatically cut off to protect the safety of the device and the silkworm eggs.

[0047] Further, the insulating cross rod 232 is connected to the upper end of the vertical support rod 231 through two through joints.

[0048] The scheme of this embodiment is that the two-way connector is made of insulating material, and the sizes of the two-way connector are matched with the horizontal rod and the vertical support rod. An adjusting knob is arranged at the connection position of the vertical support rod, which can adjust the height of the vertical support rod on the vertical support rod, so as to adjust the height of the insulating horizontal rod, and then adjust the distance between the discharge end connected on the insulating horizontal rod and the metal plate on the insulating support frame, and further adjust the distance between the electrodes according to the environmental conditions such as air humidity. When the insulating support frame is manufactured, a two-way connector with a suitable specification is selected. The inner diameter of the two-way connector should match the outer diameters of the insulating horizontal rod and the vertical support rod to ensure tight connection. When connected, one end of the two-way connector is inserted into the upper end of the vertical support rod, and then one end of the insulating horizontal rod is inserted into the other end of the two-way connector, which is fixed by using glue or other fixing methods to prevent loosening during the operation of the device and affect the stability of the device.

[0049] Further, as shown in Figure 2 , a through hole 3 is formed in the middle of the insulating horizontal rod 232, and the middle section 242 of the discharge structure extends downward through the through hole 3.

[0050] The scheme of this embodiment is that the diameter of the through hole should be slightly larger than the outer diameter of the middle section of the discharge structure to ensure that the middle section can smoothly pass through. When installing the discharge structure, the middle section is passed through the through hole of the insulating horizontal rod, and then fixed to ensure that the position of the middle section in the through hole is stable and will not shake, ensuring stable transmission of electrical signals.

[0051] Further, as shown in Figures 3-4 , in order to better show the structural features of the device, not all the fine lines are drawn. The lower end 243 includes a first fine line a and a plurality of second fine lines b. The first fine line a is a vertical fine line connected at the bottom center of the middle section 242. The second fine line b is a fold line that is inclined outward at the top and vertical downward at the bottom. A plurality of second fine lines b surround the periphery of the first fine line a, and the lower parts of a plurality of second fine lines b form a circle. The spacing between the first fine line a and the second fine line b is 1.5 cm.

[0052] Further, the ends of the fine lines are perpendicular to the metal plate 22.

[0053] Further, the diameter of the fine line is 0.5 mm, and the diameter of the lower end is 3 cm.

[0054] The scheme of this embodiment limits the specifications and distribution of fine lines to ensure that all silkworm eggs can be subjected to the same stimulation. When the fine line electrode is used as the discharge electrode of the ion wind generator, it is easier to ensure uniform specifications and good flatness during actual processing and assembly than traditional needle electrodes, thereby more conducive to ensuring the uniformity of the discharge process.

[0055] While the embodiments of the application have been disclosed as above, it is not limited to the use as set forth in the specification and the embodiments. It can be applied to various fields suitable for the application. Further modifications can be easily made by those skilled in the art. Therefore, the application is not limited to the specific details as set forth above.
