Description

Technical Field

[0001] This invention relates to the field of truck tarpaulins, and more particularly to a truck tarpaulin storage device with protective functions. Background Technology

[0002] After the waterproof coating is applied to the truck tarpaulin in the workshop, it needs to be stored. The current method of storing truck tarpaulins is to roll them up or fold them multiple times and then put them in a storage box. However, truck tarpaulins generally have a large surface area. If there is still moisture or solvent in the waterproof coating inside the tarpaulin, rolling it up directly will make it difficult for the moisture or solvent to escape from the rolled-up tarpaulin. This will make the tarpaulin prone to corrosion from the inside. In addition, the metal rings on the edges of the tarpaulin for securing the pull rope will also affect the rolling up of the tarpaulin. Furthermore, when truck tarpaulins are stored in a storage box for an extended period of time, they are prone to developing creases or marks, which can easily lead to damage.

[0017] 4. By setting anti-absorption strips, the tarpaulin body will droop between adjacent anti-absorption strips, and the tarpaulin body will not block the anti-absorption strips, so the dehumidification efficiency will not be affected, and no circular marks will be left on the tarpaulin body.

[0018] 5. By squeezing the wavy pleats of the tarpaulin body between the arc plate and the electromagnetic plate, the wavy pleats in the middle of the tarpaulin body are gradually unfolded, making it easier for moisture in the middle of the tarpaulin body to be released and reducing the amount of moisture remaining in the middle of the tarpaulin body.

[0023] The position adjustment assembly includes an electric slide rail 101, an electric slider 102, an adapter tube 103, and a washer 104. Multiple electric slide rails 101 are installed on the front and rear inner walls of the storage box 1. The electric slide rails 101 on the front and rear inner walls of the storage box 1 correspond one-to-one. Each electric slide rail 101 is slidably connected to an electric slider 102. Each electric slider 102 is fixedly connected to an adapter tube 103. Adjacent adapter tubes 103 are detachably connected to crossbars 4. Each crossbar 4 has an elastic element 4001 fixedly connected to both ends. Each elastic element 4001 has a pin head 4002 fixedly connected to it. Each crossbar 4 is slidably connected to its corresponding pin head 4002. A washer 104 is welded into each adapter tube 103. Each pin head 4002 contacts a washer 104.

[0024] The dehumidification assembly includes a partition 201, an exhaust fan 202, a hose 203, and an adapter ring 204; a collection box 1 has a manifold 1001 at the bottom; the manifold 1001 has multiple exhaust holes 1002; a partition 201 is welded to the front and rear of the manifold 1001; multiple exhaust fans 202 are installed on each partition 201; a first diversion chamber 1003 is formed between each partition 201 and the side wall of the manifold 1001; each first diversion chamber 1003 is connected to the manifold 1001 through a corresponding exhaust fan 202; a second diversion chamber 1004 is formed inside the right side wall of the collection box 1, and the upper part of the second diversion chamber 1004 is open; multiple air blowing holes 1005 are formed on the upper part of the second diversion chamber 1004; the second diversion... The cavity 1004 is connected to the storage box 1 through a corresponding air blowing hole 1005; each first diversion cavity 1003 has multiple flexible hoses 203 connected to its upper part; each adapter pipe 103 has a ventilation cavity 10301; each ventilation cavity 10301 has multiple ventilation holes 10302; each adapter pipe 103 has a rotatably connected adapter ring 204; each adapter ring 204 is used to cover the corresponding ventilation hole 10302; each crossbar 4 has an air guide cavity 4003; each air guide cavity 4003 has multiple dehumidification holes 4004; each pin head 4002 has a through hole in its middle; each air guide cavity 4003 is connected to the corresponding ventilation cavity 10301 through the through hole of the pin head 4002.

[0025] The dehumidification holes 4004 on the crossbar 4 are distributed in an X-shape on the same vertical cross section.

[0026] The specific work process is as follows: The tarpaulin body 001 is manually folded and gathered in a wave shape, starting from the long side and then the short side of the tarpaulin body 001 is folded and gathered together. Fill the manifold 1001 with a moisture-drying material; The length of storage box 1 is greater than half the long side of the tarpaulin body 001; The elastic elements 4001 and corresponding parts at both ends of the crossbar 4 are symmetrically arranged; First, control the electric cover 2 to open the storage box 1. The operator holds the crossbar 4 and moves it forward or backward, compressing the elastic element 4001 in the corresponding direction of movement. The pin head 4002 on the other side of the crossbar 4 then exits from the corresponding adapter tube 103. Next, tilt the crossbar 4 to disengage the pin head 4002 on the compressed side of the elastic element 4001 from the corresponding adapter tube 103, thus removing the crossbar 4. Repeat the above operation to remove the remaining crossbar 4. After removing all the fabric, the operator places the tarpaulin body 001, folded in a wave shape, into the storage box 1. At this point, only half of the tarpaulin body 001 is inside the storage box 1, while the other half hangs on the left edge of the storage box 1, with its end lying flat on the platform outside the storage box 1. The operator then reinstalls the crossbars 4 onto the corresponding adapter pipes 103. Finally, the operator lifts up the portion of the tarpaulin body 001 lying outside the storage box 1 and bends it to place it on the crossbars 4. Figure 4 As shown, the tarpaulin body 001 is placed in the storage box 1 in a U-shape, which effectively prevents the tarpaulin body 001 from being squeezed together and causing creases. Next, control the electric cover 2 to close the storage box 1, and control the two electric sliders 102 on the left to move upward, synchronously driving the connected adapter pipe 103 and its corresponding parts to move upward. Then, control the remaining electric sliders 102 from left to right to move upward, synchronously driving the adapter pipe 103 and its corresponding parts to move upward. The height of the electric slider 102 on the left is higher than that of the electric slider 102 on the right. Repeat the above process, so that all the crossbars 4 are tilted to the upper left and lower right when viewed from the front. Figure 4 As shown, at this time, the left turning point of the tarpaulin body 001 is also lifted upward. With the rotation of the crossbar 4, the tarpaulin body 001 and the crossbar 4 roll relative to each other, so that the tarpaulin body 001 is also in a state of left high and right low. Thus, if there is still a small amount of water on the upper part of the tarpaulin body 001, it will flow to the right on the tarpaulin body 001 and finally flow into the storage box 1. It will then enter the confluence chamber 1001 through the unsealed vent hole 1002, effectively preventing water from remaining on the tarpaulin body 001, causing the tarpaulin body 001 to rot and reduce its service life. This effectively prevents the tarpaulin body 001 from being corroded after use and ensures the normal use of the tarpaulin body 001. If the moisture on the tarpaulin body 001 fails to condense into water droplets, all exhaust fans 202 are activated. All exhaust fans 202 work together to draw air from the manifold 1001 to the first distribution chamber 1003. At this time, air from the storage box 1 enters the manifold 1001 through the exhaust port 1002. During this circulation, the air from the storage box 1 also carries moisture from the storage box 1 into the manifold 1001. The drying material in the manifold 1001 absorbs the moisture, and the dry air enters the first distribution chamber 1003. Then, the dry air passes through the hose 203 and the rotating... With ring 204, dry air enters the ventilation chamber 10301 through ventilation hole 10302. The dry air in the ventilation chamber 10301 then enters the air guide chamber 4003 through gasket 104 and hollow pin head 4002. Then it is sprayed out through dehumidification hole 4004 to the middle of the U-shaped folded tarpaulin body 001, blowing air to dry the corresponding position of the tarpaulin body 001 and taking away the moisture on the tarpaulin body 001. Then the air returns to the storage box 1 through the edge of the tarpaulin body 001. Then the moisture is absorbed and dried through the circulation of air. The storage box 1 has a second diversion cavity 1004 on the right side. The lower part of the second diversion cavity 1004 is connected to both first diversion cavities 1003. The second diversion cavity 1004 has a blower hole 1005 with an opening facing the inside of the storage box 1. Therefore, the air entering the first diversion cavity 1003 will also enter the second diversion cavity 1004. The air in the second diversion cavity 1004 will then be blown from the blower hole 1005 onto the U-shaped folded tarpaulin body 001. At this time, the tarpaulin body 001 is in a state where the left side is higher than the right side. Therefore, the dry air blown out from the blower hole 1005 blows upward along the surface of the tarpaulin body 001, completing the drying of the upper surface of the tarpaulin body 001. The blown-out moisture enters the air circulation drying simultaneously.

[0027] When the ambient temperature in the workshop rises, the storage box 1 heats up, and the temperature inside the storage box 1 also begins to rise. The increased temperature can easily cause the waterproof coating of the tarpaulin body 001 to deteriorate, affecting the waterproof performance of the tarpaulin body 001 and reducing its service life. At this time, all exhaust fans 3 are activated, and the electric cover 2 is opened simultaneously, creating a ventilation gap between the electric cover 2 and the storage box 1. The exhaust fans 3 extract the air from the storage box 1, and the hot air inside the storage box 1 accumulates in the upper part of the storage box 1. At the same time, the exhaust fan 202 is reversed, and the air in the middle part of the U-shaped tarpaulin body 001 is extracted through the dehumidification hole 4004. When the air circulates, the heat inside the storage box 1 is carried away, effectively preventing the tarpaulin body 001 from accumulating heat inside the storage box 1, which could cause local damage to the tarpaulin body 001 and reduce its local waterproof performance. This achieves overheat protection for the tarpaulin body 001, and is highly operable and practical.

[0028] Second embodiment Based on the first embodiment, according to Figure 1-4 and Figure 7 As shown, it also includes an electric actuator 301, a protective box 302, and an electromagnetic plate 303; multiple electric actuators 301 are installed at the front and rear of the storage box 1; the electric actuator 301 is an electric push rod; the telescopic parts of the electric actuators 301 at the front are all fixedly connected to an electromagnetic plate 303; the telescopic parts of the electric actuators 301 at the rear are all fixedly connected to another electromagnetic plate 303; a protective box 302 is bolted to the front and rear of the storage box 1; each protective box 302 is used to cover the corresponding electric actuator 301; each electromagnetic plate 303 has multiple vertical slots 30301; each slot 30301 is slidably connected to a connecting pipe 103; the lower parts of all electromagnetic plates 303 are slidably connected to the storage box 1.

[0029] The left and right sides of the electromagnetic plate 303 are both arc-shaped.

[0030] The edge of the tarpaulin body 001 has a metal ring for securing with a pull rope; this metal ring is ferromagnetic. Connect the two electromagnetic plates 303 to the power supply; After the tarpaulin body 001 is folded in a U-shape and stored in the storage box 1, the metal ring on the edge of the tarpaulin body 001 contacts the corresponding electromagnetic plate 303. At this time, the electromagnetic plate 303 is energized, attracting the corresponding metal ring. Then, the front electric actuator 301 is extended, simultaneously driving the front electromagnetic plate 303 to move backward. The front electromagnetic plate 303 pushes the tarpaulin body 001 backward. Next, the front electric actuator 301 is retracted, simultaneously driving the front electromagnetic plate 303 to move forward. The front electromagnetic plate 303 pulls the tarpaulin body 001 forward through the metal ring, thus unfolding the front of the tarpaulin body 001. Then, the rear electric actuator 301 is extended, simultaneously driving the rear electromagnetic plate 303 to move forward. Pushing the tarpaulin body 001 forward, then controlling the front electric actuator 301 to retract, simultaneously driving the rear electromagnetic plate 303 to move backward. The rear electromagnetic plate 303 pulls the tarpaulin body 001 backward through the metal ring, thereby unfolding the rear of the tarpaulin body 001. The extension timing of the front electric actuator 301 is staggered with that of the rear electric actuator 301. Repeating the above operation, the moisture in the wavy gaps of the tarpaulin body 001 is released while absorbing moisture, achieving more thorough dehumidification of the tarpaulin body 001 and preventing residual moisture inside the tarpaulin body 001, which would cause the tarpaulin body 001 to rot from the inside. Furthermore, by driving the movement of the tarpaulin body 001, obvious creases are effectively prevented from forming on the tarpaulin body 001.

[0031] Third embodiment Based on the second embodiment, according to Figure 1-4 and Figure 7-8 As shown, it also includes an anti-sucking strip 401; multiple anti-sucking strips 401 are fixed to the bottom of the storage box 1; multiple exhaust vents 40101 are opened on the anti-sucking strips 401; the anti-sucking strips 401 cover the corresponding dehumidification holes 1002; the electromagnetic plate 303 is slidably connected to the corresponding anti-sucking strips 401.

[0032] The exhaust vent 40101 on the anti-suction strip 401 is located in the lower middle part.

[0033] At the bottom of the storage box 1, the tarpaulin body 001 is in direct contact with the bottom of the storage box 1. When the exhaust fan 202 draws air out, the air inside the storage box 1 enters the manifold 1001 through the exhaust hole 1002. At this time, the tarpaulin body 001 is prone to blocking the exhaust hole 1002, resulting in a decrease in air dehumidification efficiency and leaving circular hole marks on the tarpaulin body 001. To address this, an arc-shaped anti-suction strip 401 is installed at the location of the exhaust hole 1002. This allows the tarpaulin body 001 to directly contact the anti-suction strip 401, preventing the tarpaulin body 001 from blocking the exhaust hole 1002. Furthermore, the exhaust vent 40101 on the anti-suction strip 401 is located in the lower middle position. Even if the tarpaulin body 001 droops between adjacent anti-suction strips 401, the tarpaulin body 001 will not block the anti-suction strips 401, ensuring that the dehumidification efficiency is not affected and that no circular marks are left on the tarpaulin body 001.

[0034] Fourth embodiment Based on the second embodiment, according to Figure 1-7 and Figure 7-10 As shown, it also includes a telescopic component 501, a fixed base 502, an arc plate 503, and an electromagnetic strip 504; multiple telescopic components 501 are connected to the bottom of the storage box 1; each electromagnetic plate 303 is fixedly connected to the telescopic part of the corresponding telescopic component 501; each telescopic part of the telescopic component 501 is connected to a fixed base 502; each fixed base 502 is hinged to an arc plate 503, the arc plate 503 is made of ferromagnetic material, and a torsion spring is provided between the arc plate 503 and the corresponding fixed base 502, the torsion spring is used to hold the arc plate 503; each telescopic part of the telescopic component 501 is connected to an electromagnetic strip 504; the electromagnetic strip 504 is used to attract the arc plate 503.

[0035] The two adjacent arc plates 503, when viewed from left to right, form an inverted figure-eight shape.

[0036] Electromagnetic strip 504 is connected to the power supply; In Embodiment 2, by pushing the tarpaulin body 001 back and forth, the wavy pleats of the tarpaulin body 001 are unfolded, releasing the moisture inside the wavy pleats. Based on this, an additional improvement is made by setting a telescopic component 501 at the lower part of the electromagnetic plate 303, and opening the movable groove of the telescopic component 501 at the bottom of the storage box 1. When the electromagnetic plate 303 moves, it also drives the corresponding telescopic component 501 to extend or retract. This effectively avoids the tarpaulin body 001 being sandwiched between the electromagnetic plate 303 and the bottom of the storage box 1 when the electromagnetic plate 303 moves, which would affect the movement of the electromagnetic plate 303 and also scratch the tarpaulin body 001 with obvious creases, making the tarpaulin body 001 more prone to damage at the creases. Furthermore, when the telescopic component 501 retracts, that is, when the telescopic component 501 moves closer to the center of the storage box 1, it simultaneously drives the fixed base 502 and related parts to move together. The arc plate 503 also moves towards the center of the storage box 1. When the arc plate 503 moves, it scrapes the wavy folds at the bottom of the tarpaulin body 001. The wavy folds are scraped and pushed upward by the arc plate 503 until they pass over the arc plate 503. At this time, one wavy fold of the tarpaulin body 001 is located between the arc plate 503 and the electromagnetic plate 303. Then, the electric actuator 301 is controlled to retract, and the arc plate 503 brings one wavy fold of the tarpaulin body 001 towards the direction of the electromagnetic plate 303. Repeat the above operation so that more of the wavy folds of the tarpaulin body 001 are squeezed between the arc plate 503 and the electromagnetic plate 303, thereby gradually unfolding the wavy folds in the middle of the tarpaulin body 001, making it easier for the moisture in the middle of the tarpaulin body 001 to be released, reducing the moisture residue in the middle of the tarpaulin body 001. Then, the electromagnetic strip 504 is de-energized, losing its magnetism. Under the action of the torsion spring, the arc plate 503 rotates towards the center of the storage box 1. Then, the wavy folds on both sides of the tarpaulin body 001, which are clamped by the arc plate 503 and the electromagnetic plate 303, are released. Following the operation process in Embodiment 2, the moisture in the front and back of the tarpaulin body 001 is fully released. When the arc plate 503 is fastened to the bottom of the storage box 1, the lower part of the wavy folds of the tarpaulin body 001 will also contact the arc plate 503 during movement, causing the tarpaulin body 001 to shake slightly up and down. This allows for more complete release of moisture from the tarpaulin body 001, facilitating the drying of the tarpaulin body 001 and thus protecting the tarpaulin body 001. The structure is simple, the effect is excellent, and the practicality is good.
