Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic cables, in particular to a grassland anti-rat and anti-ant photovoltaic cable. Background Art

[0002] Currently, photovoltaic cables use chemical-containing medicine bags to prevent rats and ants, but the durability of the medicine bags is difficult to maintain, and some sealing measures need to be taken.

[0003] For example: Chinese patent publication number CN117253660A discloses a rat- and ant-proof cable with a combustion grade of B1 and a preparation method thereof, wherein the cable comprises a core conductor, an insulating layer, a waterproof layer, an inner sheath, an armor layer, an outer sheath and a rat- and ant-proof protection block; the core conductor is wrapped inside the insulating layer, the insulating layer is wrapped inside the waterproof layer, the inner sheath is arranged outside the waterproof layer, the armor layer is arranged outside the inner sheath, the armor layer is arranged outside the inner sheath, the outer sheath is arranged outside the armor layer, the rat- and ant-proof protection block is arranged on the surface of the outer sheath, and a medicine bag with a rat- and ant-repelling function is also arranged in the rat- and ant-proof protection block; by arranging dense rat- and ant-proof protection blocks on the outer layer of the cable, rats can be prevented from directly contacting and damaging the cable, and the multi-layer structure adopted has excellent flame retardancy and protection performance, thereby ensuring the safety and stability of the cable.

[0004] However, the protective blocks still need to use special rodent-proof materials to prevent rodents from biting the photovoltaic cables, which increases the overall cost and fails to take advantage of the grassland photovoltaic cables that need to be buried underground to use medicine bags. Summary of the invention

[0005] The object of the present invention is to provide a grassland rat-proof and ant-proof photovoltaic cable to solve the above-mentioned problems.

[0006] To achieve the above-mentioned purpose, a grassland anti-rat and anti-ant photovoltaic cable is provided, which comprises a cable body and a protective sleeve arranged outside the cable body, wherein the protective sleeve is a triangular prism structure;

[0007] The three sides of the protective cover are provided with protective plates to protect the three sides of the protective cover made of conventional materials and reduce the exposed surface of the three vertices of the protective cover, making it difficult for mice to bite;

[0008] A medicine clamping channel is formed between the guard plate and the protective cover, and a double-type dispersing medicine body is arranged in the medicine clamping channel. When the photovoltaic cable is buried underground, it is affected by the soil cover, and the slowly volatilized double-type dispersing medicine body is used to drive away mice and ants.

[0009] As a further improvement of the technical solution, connection holes for connecting the guard plate are provided on the three surfaces of the protective sleeve, and the guard plate is a non-elastic hard structure bent to obtain a "U"-shaped structure;

[0010] The protective plates are arranged in plurality on the three surfaces of the cable body, and there is a diffusion gap between two adjacent protective plates on the same surface;

[0011] Wherein, the guard plate is plug-fitted into the connecting hole.

[0012] As a further improvement of the present technical solution, end caps are provided at both ends of the protective sleeve, and a wire outlet hole with an inner diameter equal to the outer diameter of the cable body is opened at the center of the end cap. The cable body can pass through the wire outlet hole. After passing through, the end caps are used to seal both ends of the medicine clamping channel.

[0013] As a further improvement of the technical solution, the outer contour of the guard plate is arc-shaped, and cooperates with the protective sleeve to form an approximately circular cross-section;

[0014] The protective cover is made of flexible material.

[0015] As a further improvement of the technical solution, an external thorn is provided on one side of the outer side of the guard plate close to the apex of the protective sleeve, and the external thorn is oriented in the tangent direction of the protective sleeve;

[0016] An inner thorn is arranged in the guard plate toward the protective sleeve.

[0017] As a further improvement of the technical solution, the cable body includes a cable core, and a filling block, an inner sheath, an armor layer and an outer sheath are sequentially arranged outside the cable core.

[0018] As a further improvement of the technical solution, it also includes a connecting plate, one end of which is provided with a horizontal plate perpendicular to the connecting plate, and the horizontal plate is arranged between the armor layer and the inner sheath;

[0019] The connecting plate passes through the outer sheath and extends into the corresponding connecting hole, and is bent in the connecting hole to form a clamping portion;

[0020] There are six connecting plates, two of which form a group and are used to connect a guard plate;

[0021] The inner sides of the plates on both sides of the guard plate are provided with clamping grooves for clamping and cooperating with the clamping parts.

[0022] As a further improvement of the technical solution, a receiving cavity is opened in the three apex parts of the protective sleeve along the length direction, and a single-type dispersing medicine body is inserted into the receiving cavity, and the single-type dispersing medicine body is used to drive away ants.

[0023] As a further improvement of the technical solution, an exposed layer is arranged outside the outer sheath on the connecting plate, and under the support of the connecting plate, a distance is provided between the exposed layer and the outer sheath to form an annular cavity;

[0024] A first notch is formed inside the accommodating cavity, and a second notch connected to the first notch is formed outside the exposed layer, wherein the volatiles of the single-type dispersing medicine body are distributed in the annular cavity through the first notch and the second notch;

[0025] The components of the single-type dispersing medicine body include sulfur compounds that can produce a pungent odor.

[0026] As a further improvement of the present technical solution, the exposed layer is made of a material that is easy to repair.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] In the grassland anti-rat and anti-ant photovoltaic cable, the cross-section of the protective sheath is designed to be approximately triangular, and no special material is used to prevent rat bites. Conventional materials can be used, such as polyethylene, polyvinyl chloride and polyurethane. The problem of rat bites is solved in two aspects:

[0029] On the one hand, the protective sleeve with a triangular cross section has increased thickness at three vertices after being wrapped around the cable body;

[0030] On the other hand, protective plates are set on the three sides of the protective cover to protect its weak points, and at the same time, the exposed surfaces at the three vertices of the protective cover can be compressed, making it difficult for mice to bite.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] At present, photovoltaic cables use medicine bags with some chemical ingredients to achieve the effect of preventing rats and ants. The effect of repelling rats and ants is achieved through the volatilization of chemical ingredients. However, for photovoltaic cables that are conventionally exposed to the air, it is difficult to maintain the durability of the medicine bags, so some measures are used to seal them.

[0048] like Figure 1 As shown, the present invention provides a grassland anti-rat and anti-ant photovoltaic cable, which takes into account the characteristics of photovoltaic cables buried underground in grasslands, exposes the dual-type dispersing drug body 320, and uses the soil covering to slow down the volatilization speed of the dual-type dispersing drug body 320, and through structural design, the outer jacket of the photovoltaic cable does not need to use special materials for anti-rat bites, such as Kevlar material.

[0049] Figure 1The cable body 100, the protective sleeve 200 and the protective plate 300 constituting the photovoltaic cable are shown. The protective sleeve 200 is arranged outside the cable body 100. The cross section of the protective sleeve 200 is designed to be approximately triangular. It does not use special materials to prevent rat bites, but conventional materials, such as polyethylene, polyvinyl chloride and polyurethane. The problem of rat bites is solved in two aspects:

[0050] On the one hand, the protective sleeve 200 with a triangular cross section has increased thickness at three vertices after being wrapped around the cable body 100;

[0051] On the other hand, the protective cover 200 is provided with protective plates 300 on three sides to protect its weak points, and at the same time, the exposed surfaces at the three vertices of the protective cover 200 can be compressed, making it difficult for mice to bite.

[0052] In addition, a medicine clamping channel is formed between the guard plate 300 and the protective cover 200, and a dual-type dispersing medicine body 320 is clamped in the medicine clamping channel. When the photovoltaic cable is buried underground, the slowly volatilized dual-type dispersing medicine body 320 plays a role in repelling mice and ants. It is not ruled out that the volatilized chemical components of the dual-type dispersing medicine body 320 can also achieve the purpose of repelling other animals.

[0053] In one embodiment, if Figure 1 and Figure 2 As shown, in Figure 1 In the embodiment, a protective sleeve 200 is disposed outside the cable body 100. The protective sleeve 200 is extruded by an extrusion molding process to obtain a triangular prism-shaped protective sleeve 200. The protective sleeve 200 is sleeved outside the cable body 100. Figure 2 As shown, connection holes 220 for connecting the guard plate 300 are opened on the three sides of the protective sleeve 200. Here, the guard plate 300 is a non-elastic hard structure (for example: plastic plate, metal plate) bent into a "U"-shaped structure. Multiple guard plates 300 are arranged on the three sides of the cable body 100, and there is a diffusion gap 310 between two adjacent guard plates 300 on the same side. Connection holes 220 are opened on the three sides of the cable body 100 at both ends of the guard plates 300, and the guard plates 300 are plugged in and matched with them, and then the double-type dispersing drug body 320 is passed through the drug clamping channel between the guard plate 300 and the cable body 100.

[0054] like Figure 1As shown, a first end cover 210a and a second end cover 210b are respectively provided at both ends of the protective sleeve 200, and a first wire outlet hole 211 and a second wire outlet hole 212 are respectively opened at the center of the first end cover 210a and the second end cover 210b. The inner diameters of the first wire outlet hole 211 and the second wire outlet hole 212 are equal to the outer diameter of the cable body 100. The cable body 100 can pass through the first wire outlet hole 211 and the second wire outlet hole 212, so that the first end cover 210a and the second end cover 210b are used to block the two ends of the drug clamping channel.

[0055] Considering the actual situation, the length of photovoltaic cables buried underground is not clear during production, so the actual production is Figure 1 The photovoltaic cable shown in the figure, that is, the protective cover 200 is equal in length to the cable body 100, which also facilitates the molding of the protective cover 200. When in use, the photovoltaic cable is first buried underground. When the photovoltaic cable is connected to the equipment, the following steps are performed: Fig.10 The steps shown are:

[0056] ①. Remove the protective plate 300 at the end of the photovoltaic cable according to the requirements of the equipment;

[0057] ② Use a cutter to cut a cut along a circular path on the outside of the protective sleeve 200. Be careful not to scratch the surface of the cable body 100 with the cutter. At the same time, ensure that the cutter can cut off the dual-type dispersing medicine body 320 and the internal structure of the protective sleeve 200, and then pull out the cut dual-type dispersing medicine body 320 and the protective sleeve 200;

[0058] Preferably, the cutter cuts a circular cut along the outer edge of the outermost protective plate 300 of the photovoltaic cable to ensure that the cross-section of the dual-type dispersing medicine body 320 and the protective sleeve 200 are flush with the outer edge of the protective plate 300 after cutting.

[0059] ③. Put the first end cover 210a or the second end cover 210b on the outside of the cable body 100, and then insert it into the outside of the double-type dispersing medicine body 320 and the protective plate 300 to block the medicine clamping channel and protect both ends of the photovoltaic cable. In addition, after using the first end cover 210a or the second end cover 210b, the defect of uneven cross-section can be compensated so that it can fit closely to the surface of the equipment.

[0060] In addition, if Figure 1As shown, the outer contour of the guard plate 300 is arc-shaped, and cooperates with the protective sleeve 200 to form an approximately circular cross-section. The approximately circular cross-section makes the structure more uniform, can better disperse and absorb external impact force, reduce local stress concentration, improve impact resistance, and facilitate coiling after production; moreover, the protective sleeve 200 is a flexible material. Although it is easy to be bitten by rats and ants, the triangular design provides a plane for the installation of the guard plate 300, and the guard plate 300 is used to protect its weak points, and the three vertices are exposed. One is to disconnect the guard plate 300. Compared with the circular metal or plastic sheath, the material cost used is reduced. Secondly, the flexible protective sleeve 200 is used to buffer the pressure, which can not only protect the guard plate 300, but also protect the internal cable body 100.

[0061] Secondly, if Figure 2 As shown, for a cable body 100 with a radius of 10-25 mm, after the protective sleeve 200 and the protective plate 300 are provided, the radius will increase to 18-33 mm, and the protective plate 300 is still the majority exposed to the outside, wherein: the three vertices of the protective sleeve 200 are protected by the protective plates 300 on the adjacent sides, and the width that can be exposed to the outside is only 6-8 mm, while the bite width of the mouth of an adult mouse is about 10-15 mm, that is, when the mouse bites the vertices of the protective sleeve 200, it will always be disturbed by the protective plate 300, and even if it can bite the protective sleeve 200, the cable body 100 will be protected due to the increase in its thickness.

[0062] In addition, Figure 2 In the embodiment, an outer spike 332 is provided on one side of the outer side of the protective plate 300 near the vertex of the protective cover 200. Under the action of the outer spike 332, it is very difficult for a mouse to walk on the vertex of the protective cover 200, and the outer spike 332 is oriented in the tangent direction of the protective cover 200 to cooperate with the vertex of the protective cover 200 to form a protective corner 333; in addition, an inner spike 331 is provided inside the protective plate 300 toward the protective cover 200, so that even if a mouse enters the drug clamping channel, it will not be able to walk due to the obstruction of the inner spike 331.

[0063] The design of the inner thorn 331 and the outer thorn 332 in this embodiment is that they are not facing outward, thereby preventing the inner thorn 331 and the outer thorn 332 from piercing the workers during laying, and continuing to maintain the overall cross-sectional shape of the photovoltaic cable (i.e., a cross-section that is approximately circular). In addition, the inner thorn 331 can also limit the dual-type dispersing drug body 320.

[0064] Working principle: Figure 1As shown, when the photovoltaic cable is buried underground and covered by the soil, the dual-type dispersing medicine body 320 can be exposed to very little air, so it will evaporate very slowly. Then, it is isolated by the protective plate 300 to form a medicine clamping channel. At this time, most of the volatiles are concentrated in the medicine clamping channel, and a small part of the volatiles diffuse into the soil through the diffusion gap 310. In addition, the ingredients of the dual-type dispersing medicine body 320 include peppermint oil, eucalyptus oil, orange oil, vaseline as a base agent, an appropriate amount of water, and ethanol or propylene glycol. Ethanol or propylene glycol can help the essential oil evaporate better, thereby enhancing the dispersing effect. The production steps are as follows:

[0065] Place the Vaseline in a small saucepan over low heat until melted;

[0066] Slowly add peppermint oil, eucalyptus oil, orange oil and ethanol or propylene glycol, stirring until completely combined;

[0067] If necessary, you can add a small amount of water to adjust the consistency of the paste, but don't add too much water, so as not to affect the insect repellent effect;

[0068] Once you’ve made sure all the ingredients are well mixed, turn off the heat and allow the paste to cool slightly;

[0069] Pour the cooled paste into a mold to form a sticky paste;

[0070] Place in a cool and ventilated place and wait for the paste to completely solidify and cool.

[0071] It is not difficult to see that the main purpose of the dual-type repellent drug body 320 is to repel rats and ants, and the volatiles can adhere to the surrounding soil. When rats or ants pass by, the volatiles can adhere to the rats or ants, so that the effect of the volatiles will last for a period of time on the rats or ants.

[0072] In addition, due to the existence of the diffusion gap 310, the influence on the bending angle of the photovoltaic cable will be greatly reduced.

[0073] In another embodiment, Figure 3-Figure 5 As shown, the connection method between the guard plate 300 and the connection hole 220 is improved. It should be noted that this embodiment should be understood as including at least all the features of any one of the aforementioned embodiments and further improving on the basis thereof.

[0074] First, the protective cover 200 is in the shape of a triangular prism, and the protective cover 200 is sleeved outside the cable body 100, see Figure 2As shown, connection holes 220 for connecting the guard plate 300 are opened on the three sides of the protective sleeve 200. Here, the guard plate 300 is a non-elastic hard structure (for example: plastic plate, metal plate) bent into a "U"-shaped structure. Multiple guard plates 300 are arranged on the three sides of the cable body 100, and there is a diffusion gap 310 between two adjacent guard plates 300 on the same side. Connection holes 220 are opened on the three sides of the cable body 100 at both ends of the guard plates 300, and the guard plates 300 are plugged and matched therewith, and then the double-type dispersing drug body 320 is passed through the drug clamping channel between the guard plate 300 and the cable body 100.

[0075] Figure 3 The guard plate 300 and the connecting plate 340 are shown in FIG. The inner side of the plate body on both sides of the guard plate 300 is provided with a card slot 342. Figure 4 As shown, the cable body 100 in this embodiment includes three cable cores 110 (different numbers of cable cores 110 are set according to the needs of the photovoltaic cable), a filling block 120 is arranged between the three cable cores 110, an inner sheath 130 is arranged outside the filling block 120, and an armor layer 140 is arranged outside the inner sheath 130. It should be noted that six connecting plates 340 are provided, two in a group, for connecting a guard plate 300, back to Figure 3 , wherein a transverse plate 341 perpendicular thereto is provided at one end of the connecting plate 340, and the transverse plate 341 of the connecting plate 340 is attached to the outside of the inner sheath 130 before the armor layer 140 is provided, and when the armor layer 140 is wound, the transverse plate 341 can be fixed to the outside of the inner sheath 130, and after being fixed, a group of two connecting plates 340 are located between their corresponding two connecting holes 220, and the angle between the two connecting plates 340 is 110-140 degrees, and in addition, an outer sheath 150 is also coated outside the armor layer 140, and the outer sheath 150 is the outer skin of the cable body 100, such as Figure 5 As shown, the connecting plate 340 passes through the outer sheath 150 and extends into the corresponding connecting hole 220, and is bent in the connecting hole 220 to form a snap-in portion. After the protective plate 300 is inserted into the connecting hole 220, the snap-in groove 342 snaps into the snap-in portion, thereby fixing the protective plate 300. In this way, even if the protective sleeve 200 is seriously damaged, the protective plate 300 can cooperate with the connecting plate 340 and the dual-type dispersing drug body 320 to protect the cable body 100.

[0076] In order to further utilize the protective cover 200, as Figure 6 As shown, a receiving cavity 230 is provided in the three apex parts of the protective sleeve 200 along the length direction. Figure 8 As shown, a single-type dispersing medicine body 233 is provided in the accommodating cavity 230. The single-type dispersing medicine body 233 is mainly used to drive away ants. Therefore, the components of the single-type dispersing medicine body 233 include:

[0077] Natural plant essential oils (such as peppermint oil, citronella oil, etc.) have the function of repelling and killing ants, and can effectively repel ants;

[0078] Silica gel or beeswax, as a carrier, can slowly release plant essential oils, prolong the duration of drug efficacy, and can give the drug body a certain hardness and formability, making it easy to make into a strip structure.

[0079] Preparation process:

[0080] Mix natural plant essential oil with silica gel or beeswax in proportion, heat the mixture in a water bath to 60-80°C, and stir evenly until it is completely melted;

[0081] The mixture is poured into a mold, left to cool and solidify into a strip-shaped structure;

[0082] If desired, a layer of beeswax can be applied to the surface of the strip to further enhance hardness and durability.

[0083] The main reason for this design is that the protective plate 300 combined with the double-type repellent medicine body 320 has a good anti-rat effect, but because the size of ants is not restricted, the possibility of ants destroying the protective cover 200 is very high, so the single-type repellent medicine body 233 is used to form a second line of defense against ants.

[0084] In addition, if Figure 6 and Figure 7 As shown, with the support of the connecting plate 340, an exposed layer 400 is provided outside the outer sheath 150 at a distance therefrom. The exposed layer 400 is made of a material that is easy to repair, such as polyvinyl chloride, polyethylene or polypropylene. When repairing these materials, the key lies in cleaning and surface treatment. First, the surrounding dirt and loose materials must be removed to ensure that the repair area is dry. Then, a suitable repair method is selected according to the type of material, such as hot melt repair, adhesive repair or patch repair. After the repair is completed, it is necessary to ensure that the repaired part is well sealed with the surrounding epidermis to ensure the insulation performance and mechanical strength of the cable; an annular cavity is formed between the exposed layer 400 and the outer sheath 150, and a first notch 231 is provided on the inner side of the accommodating cavity 230, and a second notch 232 connected to the first notch 231 is provided on the outside of the exposed layer 400, as shown in FIG. Figure 8 and Fig. 9 As shown, the volatiles of the single-type dispersing medicine body 233 are spread throughout the annular cavity through the first notch 231 and the second notch 232. Preferably, the components of the single-type dispersing medicine body 233 also include sulfur compounds such as carbon disulfide or dimethyl disulfide that can produce a pungent odor. At the same time, volatile alcohol substances such as ethanol and isopropanol can be added. These substances can increase the volatility of plant essential oils in the medicine body and enhance the diffusion effect of the odor. In this way, once the exposed layer 400 is damaged, the pungent odor will quickly diffuse, so that the damaged position can be quickly located during maintenance.

[0085] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
