Description

Technical Field

[0001] This utility model relates to the field of ecological protection technology, specifically to a protective blanket. Background Technology

[0002] Currently, in slope ecological restoration projects, the common method for protecting against acid rain erosion is to manually apply lime or slow-release neutralizing agents. However, existing technologies have the following drawbacks: 1. Poor uniformity: Traditional methods rely on manually spreading lime or neutralizing agents, which are difficult to distribute evenly on the slope, resulting in a sudden increase in pH value in some areas (>8.0), while other areas remain highly acidic (pH<4.0), affecting plant survival rate.

[0003] 2. High cost: Because the neutralizing agent is consumed quickly, it needs to be reapplied multiple times in areas with frequent acid rain, which not only increases labor and material costs, but also easily damages the restored vegetation layer.

[0004] 3. Delayed response: Existing technologies lack real-time monitoring methods for acid rain erosion. Usually, remedial measures can only be taken after samples are collected and sent for testing, resulting in continuous damage to vegetation in acidic environments and a prolonged recovery period. Utility Model Content

[0005] The technical problem to be solved by this utility model is how to deal with the protective blanket of acid rain slope in a timely manner.

[0006] This utility model solves the above-mentioned technical problems through the following technical means: This utility model provides a protective blanket, including a non-woven hydrophobic layer, a neutralizing agent interlayer, a conductive sensor mesh layer, and an LED light. The non-woven hydrophobic layer, the neutralizing agent interlayer, and the conductive sensor mesh layer are stacked and bonded together in sequence. The conductive sensor mesh layer is connected to the LED light, and the LED light is fixed on top of the non-woven hydrophobic layer.

[0007] Beneficial effects: The non-woven hydrophobic layer of this invention is hydrophobic and porous, and its pores can quickly guide rainwater and prevent rainwater from accumulating; the rainwater reacts with the neutralizing agent in the neutralizing agent interlayer after passing through the neutralizing agent interlayer, which increases the pH of the rainwater and can deal with acid rain in a timely manner; the conductive sensing mesh layer acts as a pH response layer to monitor the pH of the rainwater; when the pH of the rainwater is lower than 4.5, the conductive sensing mesh layer can drive the LED light to light up, achieving a timely response.

[0008] Preferably, the pore size of the nonwoven hydrophobic layer is 0.08mm~0.12mm, wherein the contact angle of the nonwoven fabric is greater than 150°.

[0009] Preferably, the neutralizing agent interlayer includes a filler block and a first fiber web, the filler block being connected by the first fiber web.

[0010] Preferably, the pore size of the first fiber web is 0.5mm~1.2mm, and its tensile strength is ≥10MPa.

[0011] Beneficial effects: The first fiber mesh of this utility model maintains the structural continuity between the filler blocks, which can limit the lateral spread of plant roots on the slope and allow the roots to connect laterally to form an ecological network.

[0012] Preferably, the bottom of the neutralizing agent interlayer is bonded to a second fiber mesh, the second fiber mesh having a pore size of 0.1mm to 0.3mm.

[0013] Beneficial effects: The second fiber mesh in this invention filters the products of the neutralizing agent reaction, preventing blockage of the conductive sensor mesh layer and guiding the vertical growth of the main root system of plants on the slope. Simultaneously, the neutralizing agent interlayer, through the synergistic effect of the two fiber mesh layers, allows for the replacement of the filler blocks, ensuring a root retention rate of >90% during replacement, significantly reducing the secondary construction costs of ecological restoration projects.

[0014] Preferably, the filler block is formed by hot pressing a mixture of calcium carbonate, ammonium bicarbonate and adhesive, and the filler block has a thickness of 2.5 mm to 3.5 mm, a porosity of 25% to 35%, and a pore size of 50 μm to 200 μm.

[0015] Beneficial effects: This utility model mixes calcium carbonate, ammonium bicarbonate and adhesive and then heat-presses them. The ammonium bicarbonate decomposes when heated to produce gas, which forms pores when the adhesive melts and acts as a bond. Finally, the mixture is cooled and shaped to form a filler block.

[0016] Preferably, the conductive sensing mesh layer is made of sulfonated polyaniline fiber, and the diameter of the sulfonated polyaniline fiber is 50nm~200nm.

[0017] Beneficial effects: The conductive sensing mesh layer serves as a pH response unit. The conductivity of the sulfonated polyaniline fiber decreases as the pH value decreases. When the pH value of the rainwater is 4.5 or lower, the conductivity is low enough to drive the LED light to turn on, achieving a timely response. When the pH value of the rainwater is higher than 4.5, the conductivity is high enough to fail to drive the LED light to turn on.

[0018] Preferably, the protective blanket is fixed to the slope with ecological nails, which are placed at the four corners of the protective blanket.

[0019] Preferably, the ecological nail includes a nail head and a nail post connected to the center of the nail head, with the nail post penetrating the protective blanket and anchored into the soil layer for 20cm to 25cm.

[0020] Preferably, an elastic gasket is provided between the nail head and the protective blanket.

[0021] Beneficial effects: This utility model has an elastic gasket between the nail head and the protective blanket to prevent the ecological nail from damaging the protective blanket due to stress concentration when fixing it.

[0022] Preferably, multiple protective blankets are laid on the slope, and the LED lights on each protective blanket are numbered.

[0023] Beneficial effects: This utility model can locate and maintain the corresponding protective blanket and its area based on the number of the LED light. Attached Figure Description

[0027] according to Figure 1-4 As shown, this embodiment provides a protective blanket 10 with a thickness of 4.3±0.2mm. The protective blanket 10 includes a non-woven hydrophobic layer 11, a neutralizing agent interlayer 12, a conductive sensor mesh layer 13, and an LED light 14. The non-woven hydrophobic layer 11, the neutralizing agent interlayer 12, and the conductive sensor mesh layer 13 are stacked sequentially and bonded together. The conductive sensor mesh layer 13 is connected to the LED light 14, and the LED light 14 is fixed on top of the non-woven hydrophobic layer 11.

[0028] The nonwoven hydrophobic layer 11 is a polypropylene nonwoven fabric modified with fluorocarbon resin, with a basis weight of 80±5 g / m². 2 The nonwoven hydrophobic layer 11 has a pore size of 0.08mm~0.12mm, the contact angle of the polypropylene nonwoven fabric is greater than 150°, and the water permeability is greater than 50mm / h. The nonwoven hydrophobic layer 11 has hydrophobicity and porosity, so it can quickly guide rainwater and prevent rainwater from accumulating on the surface of the protective blanket 10.

[0029] according to Figure 2 As shown, the neutralizing agent interlayer 12 includes multiple filler blocks 121 and a first fiber web 122, wherein the multiple filler blocks 121 are connected by the first fiber web 122 to form an integral structure. Rainwater reacts with the neutralizing agent in the neutralizing agent interlayer, which can increase the pH of the rainwater and effectively treat acid rain.

[0030] The filler block 121 is prepared as follows: calcium carbonate, ammonium bicarbonate and polyacrylic acid adhesive are mixed, and then hot-pressed. The ammonium bicarbonate is heated and decomposed to produce CO2. When the polyacrylic acid adhesive is heated and melts to play a bonding role, pores are generated due to CO2. Finally, the mixture is cooled and shaped to form the filler block 121. The filler block 121 has a thickness of 3.0 mm ± 0.5 mm, a porosity of 30% ± 5%, and a pore size of 50 μm to 200 μm, so that the roots of plants on the slope can penetrate the filler block 121.

[0031] The neutralizing agent interlayer 12 is bonded to the bottom of a second fiber mesh 123. Both the first fiber mesh 122 and the second fiber mesh 123 are biodegradable, with a degradation cycle of 2-3 years. The first fiber mesh 122 has a pore size of 0.5mm-1.2mm and a tensile strength ≥10MPa. Its function is to maintain the structural continuity between the filler blocks 121, restricting the lateral spread of plant roots on the slope and allowing the roots to connect laterally to form an ecological network. The second fiber mesh 123 has a pore size of 0.1mm-0.3mm. Its function is to filter the products of the neutralizing agent reaction, preventing blockage of the conductive sensing mesh layer 13 and guiding the vertical growth of the main root system of plants on the slope. The neutralizing agent interlayer 12, through the synergistic effect of the two fiber meshes, enables rapid replacement of the filler blocks 121, ensuring a root retention rate of >90% during replacement, significantly reducing the secondary construction costs of ecological restoration projects.

[0032] The conductive sensing mesh layer 13 is woven from sulfonated polyaniline fibers, with a mesh size of 2±0.5%cm × 2±0.5%cm and a fiber diameter of 50nm~200nm. The LED light 14 is connected to a power source or battery through the conductive sensing mesh layer 13, which acts as a conductor to control whether the LED light is on. The conductive sensing mesh layer 13 serves as a pH-responsive unit; the conductivity of the sulfonated polyaniline fibers decreases as the pH value decreases. When the pH value of rainwater is 4.5 or lower, the low conductivity allows the LED light to illuminate, achieving a timely response. When the pH value of rainwater is higher than 4.5, the high conductivity prevents the LED light from illuminating.

[0033] according to Figure 3 As shown, the protective blanket 10 is fixed to the slope by ecological nails 20. Multiple protective blankets 10 are laid on the slope, and each protective blanket 10 has an LED light with a number (not shown in the figure). The corresponding protective blanket 10 and the area where the protective blanket 10 is located can be located and maintained according to the number of the LED light. The ecological nails 20 are arranged at the four corners of the protective blanket 10 and are symmetrically arranged. Each ecological nail 20 is 200±20mm away from the edge of the protective blanket 10.

[0034] The ecological nail 20 includes a nail head 21 and a top post (not shown) connected to the center of the nail head 21. The nail head 21 is hexagonal with a side-to-side distance of 35mm~50mm and a thickness of 3mm~5mm. The nail post penetrates the protective blanket 10 and is anchored 20cm into the soil. Figure 4 As shown, an elastic pad 22 is provided between the ecological nail 20 and the protective blanket 10. The elastic pad 22 is circular and has a thickness of 2±0.5mm. The function of the elastic pad 22 is to prevent the ecological nail 20 from damaging the protective blanket 10 due to stress concentration when fixing the protective blanket 10.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
