Description

Technical Field

[0001] The present invention relates to the technical field of bird repellents, and in particular to a preparation method and a use method of a long-acting sustained-release bird repellent specially used for electric power. Background Art

[0002] With social development and the promotion of policies to maintain ecological balance, birds are proliferating and expanding their range. This gradual increase in bird populations, however, has led to increased bird activity, which poses a constant threat to power grid security. These hazards include: Birds nest in conductive materials like damp branches, vines, and wire, which can easily cause short circuits; bird droppings can contaminate porcelain bottles, causing line tripping; and birds can infiltrate gaps between electrical equipment like transformers, circuit breakers, and disconnectors, causing transient power outages. These threats pose a serious threat to the safe operation of the power grid, resulting in significant economic losses for both the power sector and people's livelihoods.

[0003] Currently, the main technical measures implemented on high-voltage substation equipment include: 1) installing bird droppings baffles; 2) installing bird-proof covers, bird spikes, or bird nets; 3) installing bird-proof windmills and voice-activated bird repellents; and 4) installing induction electric shock panels. While these bird-proofing measures on high-voltage substation equipment can achieve some success, they also present numerous challenges: 1) Birds easily adapt, rendering them ineffective; 2) bird-proof spikes or electric shock panels are unsafe, creating dangers for maintenance personnel who might accidentally touch them; 3) sound and light bird-repellent devices like bird-proof windmills have a limited range, and the noise or flashes they emit can pollute the surrounding environment, leading to environmental complaints; 4) ultrasonic and electric shock panels lose their functionality after a power outage, making their operation impossible to observe and measure; and 5) other bird-repellent measures are cost-prohibitive and susceptible to climate change.

[0004] In recent years, low-toxic bird repellent products have gradually emerged. For example, Chinese invention patent publication number CN 101361495 B discloses a bird repellent composition, a colloidal mixture, a suspension concentrate, and a preparation method thereof. The bird repellent fragrance is selected from one or both of anthranilate (1% to 50%), houttuynia cordata essential oil (0.1% to 5%), or musk T (10% to 21%); the antioxidant is selected from one or both of 2,6-di-tert-butyl-p-cresol and sodium ascorbate (0.02% to 0.5%), and the remainder is a sustained-release carrier. However, these products suffer from poor sustained-release effects and a short duration of efficacy. Furthermore, in rainy or windy weather, the bird repellent ingredients are easily lost, significantly reducing their effectiveness or even rendering them ineffective. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a preparation method and use method of a long-acting sustained-release bird repellent specially for power generation, and develops a new environmentally friendly long-acting bird repellent to drive away birds from nesting and frequent activities to ensure the safe and normal operation of power equipment, which is of great significance to the safe operation of the power grid.

[0006] The purpose of the present invention is achieved through the following technical solutions: In a first aspect, the present invention provides a method for preparing a long-acting sustained-release bird repellent for power generation, comprising the following steps: (1) dissolving kappa carrageenan and iota carrageenan in water to obtain a first solution; dissolving houttuynia cordata essential oil, cinnamaldehyde, and methyl anthranilate in ethanol to obtain a second solution; and dissolving potassium caseinate and calcium caseinate in water to obtain a third solution; (2) adding polyvinylidene fluoride resin, musk-T, peppermint oil, antioxidant and antifreeze agent to N-methylpyrrolidone to obtain a fourth solution; (3) adding the second solution to the first solution, stirring, adding the third solution, heating and reacting, and obtaining a colloidal mixture; (4) After the colloid mixture is cooled, the fourth solution is added and stirred to obtain a colloid agent, i.e., a long-acting sustained-release bird repellent.

[0007] The present invention adopts the low toxicity compounding of several active ingredients of Herba Houttuyniae essential oil, cinnamaldehyde, methyl anthranilate, musk-T and peppermint oil, and the compounding effect is good and can obviously enhance the effect, does not have direct lethality to birds, and is also relatively low in toxicity to humans and other mammals. However, the volatility of conventional active ingredients is strong, and the drug effect period is short, which is unfavorable for the long-term use of bird repellent. Thus, the present invention obtains a slow-release gel carrier by adding carrageenan and caseinate, and the active ingredient load is combined on the slow-release gel carrier, not only can provide a larger load capacity, slow down the release rate, and can resist the infringement of external environment (such as rain, strong wind), and the drug effect performance time is significantly extended.

[0008] Specifically, carrageenan itself has good viscosity. κ-type carrageenan forms a harder gel in the presence of potassium ions, which is used to improve the weather resistance of the bird repellent. κ-type carrageenan also forms a good bond with protein, which can improve the binding stability between carrageenan and caseinate. Io-type carrageenan forms a soft, elastic gel in the presence of calcium ions. By regulating the raw material ratio, a carrier with suitable viscosity and elasticity is obtained, which can form a good bond with the active ingredients and have a good sustained-release effect. The subsequent addition of polyvinylidene fluoride resin can improve the carrier's high temperature resistance and water resistance. In addition, adding the active ingredients in batches is conducive to achieving better dispersibility. First, Houttuynia cordata essential oil, cinnamaldehyde, and methyl anthranilate, which have multiple components, high volatility, and good compatibility with each other, are added to the preparation process of the sustained-release gel carrier. They form a physical bond with the carrier, which can absorb more active ingredients. The remaining components are then added and mixed, allowing the bird repellent to work from the beginning while also having better long-term sustained-release effect and weather resistance, and lasting longer.

[0009] Preferably, in step (1), the mass ratio of kappa carrageenan, iota carrageenan and water in the first solution is 2-3:5-7:100.

[0010] Preferably, in step (1), the mass ratio of Houttuynia cordata essential oil, cinnamaldehyde, methyl anthranilate and ethanol in the second solution is 5-10:10-15:25-30:30.

[0011] Preferably, in step (1), the mass ratio of potassium caseinate, calcium caseinate and water in the third solution is 0.5-1:2-3:100.

[0012] Preferably, in step (3), the mass ratio of the first solution, the second solution and the third solution is 5:0.8 to 1:10.

[0013] Preferably, in step (3), the heating reaction is carried out by heating to reflux for 30 to 40 minutes.

[0014] Preferably, in step (4), the mass ratio of the colloid mixture to the fourth solution is 100:1-2; and the cooling temperature is 55-65°C.

[0015] Preferably, in step (2), the mass ratio of polyvinylidene fluoride resin, musk-T, peppermint oil, antioxidant, antifreeze agent and N-methylpyrrolidone in the fourth solution is 10:3-5:10-15:0.1-0.5:2-3:20.

[0016] Preferably, in step (2), the antioxidant is ethyl hydroxybenzoate; and the antifreeze agent is ethylene glycol or glycerol.

[0017] In a second aspect, the present invention also provides a method for using a long-acting slow-release bird repellent in the power field, comprising the following steps: applying the bird repellent to power transmission facilities, hanging the bird repellent, or placing the bird repellent on the ground along the power transmission line.

[0018] Compared with the prior art, the present invention has the following beneficial effects: (1) The compounding effect is good and the efficacy is significantly enhanced through the low-toxic compounding of active ingredients. It has no direct lethality to birds and has low toxicity to humans and other mammals. (2) By adding carrageenan and caseinate to form a sustained-release gel carrier, the active ingredient is loaded and bound to the sustained-release gel carrier, which not only provides a larger load and slows down the release rate, but also can resist the damage of the external environment (such as rain and strong wind), and the duration of drug efficacy is significantly prolonged; (3) The active ingredients are added in batches to improve the physical bonding effect between them and the carrier, which can absorb more effective components. The subsequent addition of polyvinylidene fluoride resin can also improve the weather resistance of the carrier, so that the bird repellent can take effect at the beginning and has a better long-term sustained release effect and a longer effective time.

[0031] Bird repellent test: The bird repellents obtained in the examples and comparative examples were used for bird repellent operations on 10KV power lines. Each test area was 1 kilometer, and the number of power towers in each test area was 16. A 200g piece of bird repellent was placed in a matching plastic box within 0.5 meters below the area where birds are likely to cause damage or nest. The box was magnetically attached to the iron frame of the power tower where birds inhabited, with adjacent bird repellents placed 4 to 5 meters apart.

[0032] Bird landings were counted based on landings on the track and its surroundings, with no requirement for the duration of their stay. Bird landings in the corresponding area for 30 consecutive days (June 1st to June 30th) before the installation of the repellent were used as a control. Statistics were collected for each test area over a 30-day period, for a total of three consecutive periods (July 1st to September 28th). Note: Bird populations within the test area remained stable from June to September.

[0033] Table 1 As shown in Table 1, the present invention is compounded by the low toxicity of active ingredient, and compounding effect is good and can obviously enhance efficacy, there is no direct lethality to birds, and the toxicity to humans and other mammals is also relatively low, and, by adding a slow-release gel carrier, the active ingredient load is combined on the slow-release gel carrier, not only can a larger load capacity be provided, the release rate is slowed down, and the infringement of the external environment (such as rain, strong wind) can be resisted, and the drug effect is significantly extended. Comparative Examples 1-2 show that only a kind of carrageenan is added or only a kind of carrageenan is made to form a gel, and the viscosity of the carrier and the active ingredient load effect are all deteriorated, and the strength of the carrier also deteriorates, and the long-term sustained-release effect is not obvious.
