[0035] The bottom of keel 203 is provided with sliding groove 208, and one end of support frame 204 is fixedly connected with first sliding block 209, and first sliding block 209 extends to the inner chamber of sliding groove 208 and is slidably connected with it;

[0036] One end of support rod 205 is fixedly connected with second sliding block 210, and second sliding block 210 extends to the inner chamber of sliding groove 208 and is slidably connected with it;

[0037] Caster mechanism 3 includes the universal wheel 301 of fixedly being in connecting plate 207 bottom, and one side of universal wheel 301 is fixed with adjustable supporting leg 302.

[0038] When working, first, with the help of universal wheel 301 of caster mechanism 3, the whole protection device is moved to the place of construction site construction material, at this time, adjustable supporting leg 302 is in the state of being retracted, which helps the device to move flexibly, after reaching the specified position, adjustable supporting leg 302 is unscrewed, which makes it contact with the ground, and universal wheel 301 is slightly lifted, so as to ensure that the device is stably placed and prevents sliding during use.

[0039] When it is necessary to stack materials in a larger site, the support frame 204 is pushed to move outward, which synchronously expands the support rod 205 outward, at this time, the first sliding block 209 and the second sliding block 210 slide outward in the sliding groove 208 at the bottom of the keel 203, which promotes the keel 203 to rotate outward around the pin joint of the connecting block 202 and the main keel 201, the main keel 201 is lowered, and then the unfolding angle is increased, when the thickened canvas 1 is unfolded to the required coverage area, the pushing is stopped, and the positioning is completed through the adjustable support foot 302.

[0040] When the site space is limited, the support frame 204 is pushed in the opposite direction to move inward, which synchronously shrinks the support rod 205 inward, at this time, the first sliding block 209 and the second sliding block 210 slide inward in the sliding groove 208 at the bottom of the keel 203, which promotes the keel 203 to rotate inward around the pin joint of the connecting block 202 and the main keel 201, the main keel 201 is raised, thereby reducing the unfolding angle, after the thickened canvas 1 is shrunk to the coverage area suitable for the narrow space, the pushing is stopped, and the adjustable support foot 302 is tightened again to fix the position of the device, which ensures that the device can still be stable and protective in the limited space.

[0041] The adjustment mode of the structure design is simple to operate, does not require complex tools, can quickly adapt to the actual needs of different sites, reduces the labor operation strength and time cost, avoids the waste of resources caused by the disassembly and reconstruction of the protective shed, and can maximize the use of construction space by flexible adaptation to site changes.

[0042] Embodiment 2

[0043] Please refer to Figure 1 , Figure 2 and Figure 6 The difference between the embodiment 1 is that the two ends of the two side support frames 204 are fixedly connected with the fixed rods 206, and the fixed rods 206 are fixedly connected with all the support frames 204, thereby forming an overall frame structure.

[0044] The two ends of the thickened canvas 1 are fixedly connected with the gravity rods 4, the surface of the gravity rod 4 is provided with a sliding hole 5 corresponding to the support frame 204, and the sliding hole 5 is movably inserted with the support frame 204.

[0045] By fixing the fixed rod 206 to all the support frames 204 on both sides to form an integral frame, the overall rigidity and stability of the support structure can be significantly improved. This effectively avoids the swaying or displacement that may occur when a single support frame 204 is under force, making the support of the thickened canvas 1 more stable and reliable. At the same time, the gravity rods 4 at both ends of the thickened canvas 1 are movably inserted into the support frame 204 through the sliding holes 5. When the thickened canvas 1 is unfolded or retracted, the gravity rods 4 can slide smoothly along the support frame 204. The weight of the gravity rods 4 themselves can generate a continuous downward force on both ends of the thickened canvas 1, ensuring that the thickened canvas 1 can maintain sufficient tension in the unfolded state, avoiding wrinkles or loosening of the surface of the thickened canvas 1 due to external factors such as wind, thereby ensuring effective coverage and protection of the construction materials. During the retraction process, the sliding cooperation between the gravity rods 4 and the support frame 204 also makes the retraction of the thickened canvas 1 more orderly and less prone to tangling or jamming, further optimizing the ease of operation and reliability of the device.

[0046] Example 3

[0047] Please see Figure 1 , Figure 2 and Figure 5 The difference from Embodiment 1 is that the bottom of the four-sided support frame 204 is fixedly connected to the connecting plate 207, and the bottom of the connecting plate 207 is provided with a caster mechanism 3.

[0048] By installing a caster mechanism 3 at the bottom of the support frame 204, the entire protective device has convenient mobility. When it is necessary to protect construction materials in different locations or to adjust the protection area according to the construction progress, the operator can easily push the device and move it flexibly on the construction site ground through the caster mechanism 3 without the need for cumbersome disassembly and reinstallation, saving manpower and time costs. The setting of the connecting plate 207 provides a stable connection transition between the caster mechanism 3 and the support frame 204, ensuring that the caster mechanism 3 can reliably bear the overall weight of the device and the weight of the protective materials, ensuring the structural stability of the device during movement, and avoiding the risk of tipping or damage due to loose connection.

[0049] Example 4

[0050] This embodiment is based on embodiment 1 or embodiment 2, such as Figure 7 Furthermore, intelligent monitoring components have been added to enhance the safety and early warning capabilities of the device at the construction site.

[0051] A rain sensor and a wind speed sensor are bolted to the highest point of the main keel 201. Because the main keel 201 is located at the very top of the device, this position is the first to come into contact with rainwater and accurately capture the ambient wind speed, unaffected by surrounding obstructions.

[0052] A control box and an audible and light alarm are fixedly installed at a position on the outer side wall of the support frame 204 that is convenient for personnel to observe. The control box has a microprocessor and a power module integrated inside. At the same time, an inclination sensor is installed on the side of the vertical rod body of the support frame 204.

[0053] A smoke sensor is fixedly installed on the inside bottom of the keel 203, i.e., above the internal space covered by the thickened canvas 1.

[0054] The embodiment gives the protection device environmental perception ability through the spatial layout of the physical sensors, making up for the passivity of pure mechanical protection. When the rainfall sensor detects rainfall or the wind speed sensor detects wind speed exceeding the set threshold, such as strong wind weather, the signal is transmitted to the control box, triggering the audible and light alarm to issue an alarm. This can timely remind the workers on the construction site: if the device is in the retracted state, the thickened canvas 1 needs to be quickly deployed to cover the materials; if the wind speed is too large, the workers are reminded to check whether the adjustable support feet 302 of the truckle mechanism 3 are locked or to additionally reinforce the device to prevent it from being blown over.

[0055] When the workers push the support frame 204 to deploy or retract, or the device moves on uneven ground, the inclination sensor monitors the perpendicularity of the support frame 204 in real time. Once the inclination angle of the device exceeds the safe range and is about to fall under the action of gravity, the control box immediately controls the alarm to alarm, prompting the workers to stop moving or adjusting the ground flatness, effectively avoiding the heavy protection device from falling and causing injury or damage to the materials due to improper operation. Since flammable materials are often stacked on the construction site, the smoke sensor located at the top can monitor the internal condition of the protection space at all times. Once the smoke caused by spontaneous combustion of the materials or external sparks is detected, the external audible and light alarm is immediately alarmed, so that the management personnel can quickly discover and handle the fire in the early stage, greatly ensuring the fire safety of the construction site.

[0056] In summary, the embodiment integrates the rainfall sensor and the wind speed sensor at the top of the main keel 201, so that the device has all-weather environmental perception ability. When the construction site is busy or unattended at night, if sudden rainfall or strong wind occurs, the device can first alarm through the audible and light alarm. This can timely remind the construction personnel to quickly deploy the thickened canvas to cover the materials or check the locking state of the support feet to prevent the device from being blown over, thereby effectively avoiding the economic loss of the materials caused by weather changes such as rusting of the reinforcement and dampening of the cement.

[0057] In view of the fact that the ground of a construction site is usually uneven, and the device has a certain height and weight, there is a risk of tipping during movement or expansion / contraction. By setting an inclination sensor, the system can monitor the verticality and balance of the support frame in real time. Once the device is tilted due to uneven ground or uneven pushing force, the alarm will immediately prompt the worker to stop operating and adjust the posture, fundamentally eliminating the construction safety hazards of device tipping, injury or equipment damage.

[0058] The construction material storage area is often a visual blind area due to tight covering, and some packaging materials are flammable. By setting a smoke sensor inside the keel, the device can continuously monitor the fire in the closed space covered by the thickened canvas. Once smoke is detected inside, such as due to spontaneous combustion or external sparks, the external alarm will be triggered immediately, allowing management personnel to quickly discover and intervene at the early stage of the fire, filling the fire safety gap of traditional simple protective sheds.

[0059] The fixed rod 206 connects the two side support frames 204 into a whole frame, which, in cooperation with the downward pulling effect of the gravity rod 4 on the canvas, ensures the structural rigidity and canvas tension of the device in the expanded state. In combination with the above intelligent early warning, the device realizes the intelligent upgrade from single "physical shielding" to "shielding + monitoring + early warning", which not only ensures the stability and durability of the mechanical structure, but also enhances the dual protection of construction materials and operating personnel through technological means.

[0060] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range of those skilled in the art without departing from the purpose of the utility model.
