Description

Technical Field

[0001] This application relates to the field of building construction, and in particular to a mobile retractable protective shed. Background Technology

[0002] A protective canopy is a protective and safety measure used to shield equipment, facilities, tools, vehicles, etc., and has functions such as waterproofing, dustproofing, and sun protection.

[0003] The related technology involves a protective canopy, including beams, which are slidably connected by telescopic rods. The outer walls of all beams are covered with protective fabric. When using the protective canopy, the beams are pulled, causing them to move away from each other under the action of the telescopic rods, thereby increasing the length of the protective canopy.

[0004] Regarding the aforementioned technologies, the protective fabric of the telescopic protective canopy often expands or contracts. When the beam frame contracts, after the protective canopy is folded back, the protective fabric between the beam frames will also be wetted by rain or exposed to ultraviolet rays, which will cause its performance to decline. Therefore, it needs to be improved. Summary of the Invention

[0005] To improve the durability of protective sheds, this application provides a mobile telescopic protective shed.

[0006] The mobile retractable protective shed provided in this application adopts the following technical solution:

[0007] A mobile retractable protective canopy includes a mounting frame and a shielding cloth. The mounting frame includes a first support beam, a second support beam, a third support beam, and several telescopic hinge rods. The first and second support beams are slidably connected by the telescopic hinge rods, and the second and third support beams are also slidably connected by the telescopic hinge rods. The shielding cloth is laid on the outer wall of the mounting frame. The outer wall of the shielding cloth is provided with a first connecting plate corresponding to the first support beam, a second connecting plate corresponding to the second support beam, and a third connecting plate corresponding to the third support beam. The second connecting plate is provided with a support frame in which a reinforcing cloth is placed. A lifting component for driving the reinforcing cloth to move is provided at the second connecting plate, and an unfolding component for driving the reinforcing cloth to unfold is provided at the third connecting plate.

[0008] By adopting the above technical solution, when the protective shed is not in use and is retracted, the lifting component is driven, which lifts the reinforcing cloth upward. Then, the stretching component is activated, which unfolds the reinforcing cloth, thereby protecting the mounting frame. This effectively reduces the occurrence of damage to the protective shed when it is closed and retracted, thereby reducing the damage to the shielding cloth from the external environment and further improving the durability of the protective shed, thus effectively extending its service life.

[0009] Preferably, the lifting assembly includes a mounting motor, a rotating rod, and a connecting rope. The mounting motor is connected to a second connecting plate, the rotating rod is connected to a coupling of the mounting motor, one end of the connecting rope is connected to the rotating rod, and the other end of the connecting rope is connected to a reinforcing fabric.

[0010] By adopting the above technical solution, when the protective shed is closed, the installation motor is started, the installation motor drives the rotating rod to rotate, and then the connecting rope is wound around the surface of the rotating rod, which causes the connecting rope to move the reinforcing cloth upward, thereby causing the reinforcing cloth stacked in the support frame to rise from the support frame to the side wall of the installation frame, and making it easier to unfold the reinforcing cloth by the subsequent stretching assembly.

[0011] Preferably, the stretching assembly includes a bidirectional lead screw, a first unfolding block, a second unfolding block, a first magnetic component, a first adsorption component, a second magnetic component, a second adsorption component, a forward and reverse motor, a mounting block, and a guide rod; the mounting block is connected to a third connecting plate, the mounting block is connected to the forward and reverse motor, one end of the bidirectional lead screw is connected to the coupling of the forward and reverse motor, the guide rod is connected to the mounting block, the first unfolding block is sleeved on both the bidirectional lead screw and the guide rod, the second unfolding block is sleeved on both the bidirectional lead screw and the guide rod, the first magnetic component is connected to the first unfolding block, the second magnetic component is connected to the second unfolding block, the first adsorption component corresponds to the first magnetic component, the first adsorption component is connected to the reinforcing fabric, the second adsorption component corresponds to the second magnetic component, and the second adsorption component is connected to the reinforcing fabric.

[0012] By adopting the above technical solution, after the lifting component drives the reinforcing cloth to rise, the first adsorption component at the reinforcing cloth and the first magnetic component at the first unfolding block are magnetically attracted to each other, and the second adsorption component at the reinforcing cloth and the second magnetic component at the second unfolding block are magnetically attracted to each other. Then, the forward and reverse motors are started, and the forward and reverse motors drive the bidirectional lead screw to rotate, and the first unfolding block and the second unfolding block move away from each other, so that the reinforcing cloth covers the side wall of the mounting frame, thus protecting the covering cloth and improving the service life of the covering cloth.

[0013] Preferably, the mounting block includes a rotating block, a mounting shaft, and a torsion spring. The forward and reverse motors are connected to the rotating block, the guide rod is connected to the rotating block, one end of the mounting shaft is rotatably connected to the rotating block, and the other end of the mounting shaft is rotatably connected to a third connecting plate. The torsion spring is sleeved on the mounting shaft, and the third connecting plate is provided with a locking device for fixing the bidirectional lead screw.

[0014] By adopting the above technical solution, when the protective canopy is unfolded, the rotating block is rotated, and the bidirectional lead screw and guide rod follow the rotating block. Then, the bidirectional lead screw is fixed by the locking device, so that the bidirectional lead screw is set along the height direction of the mounting frame. After the protective canopy is unfolded, the bidirectional lead screw is stored, further reducing the occurrence of the bidirectional lead screw interfering with the use of the protective canopy. When the protective canopy is retracted, the locking device is adjusted, and under the action of the mounting shaft and torsion spring, the rotating block rotates, making the bidirectional lead screw horizontal, so as to facilitate the use of the extended assembly.

[0015] Preferably, the locking component includes a locking block, a locking rod, and a locking bolt. The locking block is connected to a third connecting plate. The locking block has a positioning groove for inserting a bidirectional lead screw. The bidirectional lead screw has a locking groove. The locking rod is inserted into the locking block and passes through the locking groove. The locking bolt is sleeved on the locking rod and threadedly connected to the locking rod.

[0016] By adopting the above technical solution, after the bidirectional lead screw rotates, it is inserted into the locking groove of the locking block. Then, the locking rod is inserted into the locking block and passes through the positioning groove. Finally, the locking rod is positioned by the locking bolt, thus fixing the bidirectional lead screw.

[0017] Preferably, a receiving frame is provided below the support frame, a water pump is provided in the receiving frame, the water pump is connected to a spray pipe, the spray pipe passes through the receiving frame, a spray head is provided at the end of the spray pipe away from the water pump, and a drive component for driving the spray pipe to move is provided at the mounting plate.

[0018] By adopting the above technical solution, when the protective shed is unfolded, the spray pipe is raised by the drive component, and then the water pump is activated. The water in the frame is transported to the spray pipe by the water pump and sprayed out through the spray head to clean the cover cloth. This allows the dust and other debris attached to the surface of the cover cloth to be cleaned in time, thereby improving the cleanliness of the cover cloth.

[0019] Preferably, the drive assembly includes a drive motor, a lifting rod, and a drive block. The drive motor is connected to the receiving frame, the lifting rod is connected to the drive motor via a coupling, the drive block is sleeved on the lifting rod, the side wall of the drive block is abutted against the side wall of the second connecting plate, and the drive block is connected to the spray pipe.

[0020] By adopting the above technical solution, the drive motor is started, which drives the lifting rod to rotate, thereby causing the drive block to move along the height direction of the lifting rod. This allows the spray head of the spray pipe to rise or fall with the drive block, thereby adjusting the spray range on the surface of the cover cloth and further improving the cleaning effect on the cover cloth.

[0021] Preferably, the third connecting plate is equipped with a disassembly block, the disassembly block is provided with a synchronous motor, the coupling of the synchronous motor is provided with a synchronous lead screw, the disassembly block is provided with a sliding rod, the sliding rod and the synchronous lead screw are jointly sleeved with a sliding block, the driving block includes a first moving block and a second moving block, the sliding block is provided with a third magnetic element, and the first moving block is provided with a third adsorption element that is magnetically attracted to the third magnetic element.

[0022] By adopting the above technical solution, when the drive block rises above the lifting rod, the third adsorption component at the first moving block and the third magnetic component at the sliding block attract and adhere to each other. Then, the synchronous motor is started, and the synchronous motor drives the synchronous screw to rotate. The sliding block and the first moving block move synchronously along the length direction of the synchronous screw. The spray pipe and the spray head follow the sliding block and move together along the length direction of the synchronous screw, so that the spray pipe can further spray the surface of the shielding cloth at different positions.

[0023] Preferably, the first movable block is provided with a plug-in block, and the second movable block is provided with a plug-in slot for the plug-in block to be inserted.

[0024] By adopting the above technical solution, after the spray pipe follows the sliding block to clean the shielding cloth, the first moving block moves back to the second moving block. At this time, the plug of the first moving block is inserted into the plug slot of the second moving block and locked in place. The first synchronous block continues to move along the length of the synchronous screw and makes the third magnetic component and the third adsorption component move away from each other. Then the drive motor is restarted, so that the entire drive block moves along the length of the lifting rod and descends into the receiving frame to facilitate the adjustment of the position of the spray pipe.

[0025] Preferably, the end of the connecting rod away from the lifting rod is provided with a disassembly block, the disassembly block is provided with an installation rod, and the installation rod passes through the disassembly block and is threadedly connected to the third connecting plate.

[0026] By adopting the above technical solution, after the protective shed is closed at the end of its use, the mounting rod is rotated and separated from the third connecting plate. Then the disassembly block can be disassembled for easy storage.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. After the protective canopy retracts, the drive lifting component raises the reinforcing fabric, and then drives the stretching component to unfold the reinforcing fabric along the length of the mounting frame, thereby protecting the side wall of the protective fabric and reducing the occurrence of damage to the protective fabric from the external environment, further improving the durability of the protective fabric.

[0029] 2. A locking device is installed at the third connecting plate. When the protective shed is unfolded, the double-acting screw is rotated so that the double-acting screw is inserted into the locking groove at the locking block, and the double-acting screw is fixed by the locking rod, so that the double-acting screw is fixed along the height direction of the mounting frame, thereby effectively improving the stability of the double-acting screw when the protective shed is used.

[0030] 3. When the protective shed is unfolded, start the drive motor. The drive motor drives the lifting rod to rotate, which in turn causes the drive block to lift the spray pipe. After starting the water pump, the water in the frame is collected and cleaned by the spray pipe and spray head on the surface of the protective shed, thereby effectively improving the cleanliness of the surface of the cover cloth.

The third connecting plates 131 are attached to the outer wall of the shielding cloth 2. The third connecting plates 131 are connected to the third support beam 13 by screws, and the screws pass through the shielding cloth 2. The lower end of the first connecting plate 111, the lower end of the second connecting plate 121, and the lower end of the third connecting plate 131 are fixedly connected to two moving wheels 15 by screws.

[0042] The lower end of the second connecting plate 121 is fixedly connected to a support frame 122 by screws. A reinforcing cloth 123 is stacked in the support frame 122. The reinforcing cloth 123 can protect the shielding cloth 2, thereby effectively reducing the phenomenon of external damage to the reinforcing cloth 123 and thus improving the service life of the shielding cloth 2. A lifting component 3 for driving the shielding cloth 2 to rise or fall is installed at the second connecting plate 121, and a stretching component 4 for driving the shielding cloth 2 to unfold is provided on the third connecting plate 131.

One end of the connecting rope 33 is fastened to the rotating rod 32, and the other end of the connecting rope 33 is fastened to the center of the upper end of the reinforcing cloth 123. After rotating the mounting motor 31, the connecting rope 33 drives the reinforcing cloth 123 to rise, so as to protect the shielding cloth 2.

The mounting block 49 is connected to the third connecting plate 131 and the forward and reverse motor 48. The coupling of the forward and reverse motor 48 is connected to a bearing at one end of the bidirectional lead screw 41. The guide rod 410 is connected to the mounting block 49 and extends along... The bidirectional lead screw 41 is positioned along its length. A first unfolding block 42 is fitted onto the bidirectional lead screw 41 and the guide rod 410.

The first adsorption component 45 corresponds to the first magnetic component 44, and the second adsorption component 47 corresponds to the second magnetic component 46. After the lifting assembly 3 drives the reinforcing cloth 123 to rise, the first magnetic component 44 and the first adsorption component 45 attract each other, and the second magnetic component 46 and the second adsorption component 47 attract each other. Then, the forward and reverse motor 48 is started, which drives the bidirectional lead screw 41 to rotate, thereby causing the first unfolding block 42 and the second unfolding block 43 to move away from each other, so that the reinforcing cloth 123 can unfold for use as a shielding cloth 2 for protection, thereby improving the durability of the shielding cloth 2.

The other end of the mounting shaft 492 is connected to the bearing on the surface of the third connecting plate 131. The torsion spring 493 is sleeved on the mounting shaft 492. A locking member 5 for fixing the bidirectional screw 41 is installed at the lower end of the third connecting plate 131. When the protective shed is closed and retracted, the bidirectional screw 41 is in a horizontal state to facilitate the unfolding of the reinforcing fabric 123. When the protective shed is in the open state, the bidirectional screw 41 is rotated to make the bidirectional screw 41 in a vertical state and is fixed by the locking member to facilitate the adjustment of the length of the protective shed.

The end of the bidirectional lead screw 41 away from the forward and reverse motor 48 has a locking groove 411 extending radially through it. After the bidirectional lead screw 41 is inserted into the locking block 51, the locking rod 52 is inserted into the positioning groove 511 and passes through the locking groove 411, thereby fixing the bidirectional lead screw 41. The locking bolt 53 is sleeved on the locking rod 52, and the threads of the locking bolt 53 and the locking rod 52 are adapted to each other, thereby further fixing the locking rod 52 and improving the stability of the locking component 5 when fixing the bidirectional lead screw 41.

In this embodiment, the third magnetic element 841 is a magnet, and the third adsorption element 7312 is an iron sheet. After the first moving block 731 and the second moving block 732 move along the length direction of the lifting rod 72 to the upper end of the lifting rod 72, the first moving block 731 disengages from the lifting rod 72, and the magnetic element of the sliding block 84 and the adsorption element of the first moving block 731 attract and adhere to each other, so that the first moving block 731 and the sliding block 84 are connected. Then, the synchronous motor 83 is started, so that the sliding block 84 drives the first moving block 731 to move along the length direction of the sliding rod 82, thereby driving the spray pipe 62 to move, so as to spray and clean the shielding cloth 2 at different positions, further improving the cleaning effect of the shielding cloth 2.

The installation nut is threadedly connected to the installation rod to facilitate timely installation and disassembly of the disassembly block 8.

[0051] The implementation principle of a mobile telescopic protective shed according to an embodiment of this application is as follows: When the protective shed is not in use, the first support beam 11, the second support beam 12, and the third support beam 13 move closer to each other, reducing the overall length of the protective shed. Then, the installation motor 31 is started, and the rotating rod 32 drives the connecting rope 33 to rise and rewind to the rotating rod 32. At this time, the reinforcing cloth 123 rises. Then, the forward and reverse motor 48 is started, causing the bidirectional lead screw 41 to drive the first unfolding block 42 and the second unfolding block 43 to move away from each other, thereby causing the reinforcing cloth 123 to unfold along the length of the protective shed to cover the shielding cloth 2, thereby protecting the shielding cloth 2 and reducing the occurrence of damage to the shielding cloth 2 caused by the external environment when the protective shed is in use.

[0052] This specific embodiment is merely an explanation of this application and is not intended to limit it. Based on the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this application. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of this application should be covered within the protection scope of this application.
