Description

Technical Field

[0001] The present invention relates to the technical field of construction enclosures, and in particular to an environmentally friendly construction enclosure with a warning function. Background Art

[0002] In order to ensure an effective safe space near the construction site during the construction process, construction fences are needed for isolation and separation. Fencing refers to the measures taken to isolate the construction site from the external environment and make the construction site a relatively closed space, including walls built with various masonry materials and maintenance bodies made of various molded panels.

[0003] However, the fences in the existing technology are fixed in length, width and height, and are large in size. Workers combine fences piece by piece to form a fence wall, and cannot flexibly adjust the height of the fence according to the construction site. It is also very inconvenient to carry or transport. Even if the height of the fence can be adjusted, workers usually have to pull it up or lift it manually, which requires a lot of upper limb strength. If the workers have something in their hands or are doing other work, they cannot raise the fence at the same time. In addition, the warning function of the existing fences is not obvious during use, especially at night, due to poor light, it is basically useless. It does not serve the purpose of warning. If a lighting device is added, a separate external power cord needs to be connected. If a solar panel is added, the angle of the solar panel is usually fixed, and the angle of the solar panel cannot be adjusted according to the light angle, resulting in low solar energy utilization. Because there is too much dust at the construction site, the surrounding environment is polluted. At the same time, many warning signs provided by fences at night will also be attached by dust, resulting in a decrease in the warning effect. It is easy to cause passers-by to see unclearly and touch them by mistake, which poses certain safety hazards. Therefore, an environmentally friendly construction fence with a warning function is proposed to solve the above-mentioned problems. Summary of the Invention

[0014] Compared with the prior art, the present invention provides an environmentally friendly construction enclosure with a warning function, which has the following beneficial effects:

[0015] 1. This environmentally friendly construction fence with a warning function uses a trigger device that allows the operator to directly expand the telescopic device when stepping on it, raising the fence without using hands, thereby directly pulling up the entire pull-up plate, so that the entire device forms a fence to be used for isolating the surrounding construction environment. This greatly saves workers' physical strength. Even if workers are holding other objects or doing other work, they can use their feet to raise the fence, which greatly improves work efficiency. The height of the fence can also be controlled to a certain extent, thereby coping with the isolation of different working environments. At the same time, because the entire fence adopts a retractable expansion structure, it is extremely convenient to transport and carry.

[0016] 2. The environmentally friendly construction fence with warning function can provide a certain degree of warning to the surrounding personnel through the roll-up pull tabs. The warning structure of the entire device adopts the combination of logo and luminous display to achieve all-day warning. Even at night, the triangular warning light can illuminate the warning sign and provide the maximum surrounding warning effect.

[0017] 3. The environmentally friendly construction fence with warning function can store solar energy during the day through the lighting device, which is convenient for subsequent electricity use at night. The electricity stored during the day is used to provide a display for the light bulb, thereby achieving energy saving and environmental protection, and avoiding the traditional method of wiring. A pull rope is connected to the lifting pole, and one end of the pull rope is connected to the solar panel. The solar panel is rotatably connected to the upper pull plate. When the light bulb rises, it will drive the pull rope to rise, and then drive the solar panel to rotate, thereby forming a flat state to maximize the reception of solar energy. The height of the fence can also be adjusted according to the position of the sunlight, thereby adjusting the angle of the solar panel to maximize the utilization of solar energy.

[0018] 4. This environmentally friendly construction enclosure with a warning function can spray water around the construction area through the dust suppression device, achieving an automatic dust reduction effect, thereby reducing the surrounding dust and improving the surrounding construction environment. This environmentally friendly construction enclosure with a warning function can increase the overall range of water spraying and dust reduction by controlling the rotation of the nozzle through water pressure, and can spray water onto the solar panels and warning signs to achieve cleaning, thereby preventing dust adhesion and reducing the warning effect.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0031] See also Figure 1-10 An environmentally friendly construction fence with a warning function includes an upper pull-up plate 1, a lighting device 4 is provided on the upper pull-up plate 1, the bottom of the upper pull-up plate 1 is connected to a lower base 2 through a telescopic mechanism 3, a warning device 5 is provided inside the lower base 2, a trigger device 7 is provided on the lower base 2, and a dust suppression device 6 is provided inside the upper pull-up plate 1.

[0032] In this embodiment, the telescopic mechanism 3 includes a connecting tooth plate 301, a first gear 302 is engaged on the connecting tooth plate 301, the first gear 302 is rotatably connected to the inner core of the lower base 2, a first support rod 303 is fixedly connected to the first gear 302, one end of the first support rod 303 is connected to a positioning plate 306, the front of the positioning plate 306 is fixedly connected to the second gear 304, the second gear 304 is engaged with a third gear 305, the axis of the third gear 305 is fixedly connected to the second support rod 307 through an axis, the top of the second support rod 307 is rotatably connected to the inside of the upper pull plate 1, and the connecting tooth plate 301 is connected to the trigger device 7. When the first support rod 303 is rotated by the rotation of the gear, the rotation of the first support rod 303 will drive the relative rotation of the second gear 304, and the rotation of the second gear 304 will drive the meshing rotation of the third gear 305. The second support rod 307 is fixed on the third gear 305, so at this time the second support rod 307 will rotate relatively, thereby causing the first support rod 303 and the second support rod 307 to spread apart, raising the upper pull-up plate 1, thereby forming an overall enclosure, thereby facilitating its overall installation and disassembly without unnecessary steps, making it convenient to carry and convenient for multiple batches of transportation.

[0033] Furthermore, the trigger device 7 includes a connecting plate 73, both sides of which are fixedly connected to the connecting tooth plate 301, the front of the connecting plate 73 is slidably connected to the lower base 2 through an axle, the front of the connecting plate 73 is fixedly connected to a pedal 71, a positioning device 72 is provided on the pedal 71, and a spring is provided between the connecting plate 73 and the lower base 2, and the provided spring is capable of achieving a retracted return, because relying on the gravity on the upper pull plate 1, when the pin 722 is disengaged from the socket 723, it is directly affected by the gravity effect of the upper pull plate 1 to achieve a return, and the provided spring is capable of achieving a certain buffer to avoid damage to the equipment. By directly pressing the pedal 71, the connecting plate 73 moves downward, thereby driving the connecting tooth plate 301 to move downward, and then through the meshing transmission between the gear and the tooth plate, the linear motion is converted into rotational motion, thereby driving the entire enclosure to rise and unfold, without the need for redundant installation steps, achieving rapid disassembly and recovery, improving its overall work efficiency, and reducing work intensity.

[0034] Furthermore, the positioning device 72 includes a rotating plate 721, with a latch 722 fixedly connected to the bottom of the rotating plate 721. The lower base 2 is provided with multiple sockets 723 that mate with the latch 722. The rotating plate 721 is rotatably connected to the pedal 71. A connecting spring 724 is fixedly connected to the rotating plate 721, one end of which is fixedly connected to the pedal 71. The operator presses the latch 722 at the bottom of the foot rotating plate 721 into the socket 723 provided on the lower base 2, thereby inserting and securing the foot plate 721. Because the height to which the connecting gear plate 301 is lowered varies, the height to which the entire enclosure is raised will also vary. Therefore, the multiple sockets 723 are provided to accommodate fixing at different heights.

[0035] In addition, the warning device 5 includes a roll-up pull tab 501, one end of which is fixedly connected to two hanging rings 502, one end of which is fixedly connected to a rotating shaft 505, and both ends of the rotating shaft 505 are rotatably connected to the inside of the lower base 2, a warning light 503 is provided on the roll-up pull tab 501, and a reminder sign 504 is provided at the center position of the warning light 503, and a hook is installed on the second support rod 307 to cooperate with the hanging ring 502. Taking into account the need for full shielding in some construction areas, a roller shutter-type pull-up tab 501 is provided. The pull-up tab 501 itself has a certain degree of bending elasticity, similar to the nature of a tape measure, and can be pulled up and automatically retracted. At this time, if full shielding is achieved, the operator can hang the two hanging rings 502 on the pull-up tab 501 on the hook of the second support rod 307 to achieve full shielding, and a warning light 503 and a prompt sign 504 are provided on the pull-up tab 501 to provide warnings to passers-by in the surrounding area. In addition, during the night, the triangular sign formed by multiple warning lights 503 can provide warnings and illuminate the prompt sign 504, so that passers-by in the surrounding area can clearly see the warning sign and provide timely avoidance effect.

[0036] In addition, the upper pull plate 1 is rotatably connected to a connecting rod 1 507, one end of which is rotatably connected to a connecting rod 2 508, the bottom of which is rotatably connected to the lower base 2, and the connecting rod 1 507 is rotatably connected to a prompt rod 506, the surface of which is coated with luminescent powder, which can produce a nighttime glowing effect without the need for electrical components. The diamond-shaped bracket formed by the two connecting rods 1 507 and the two connecting rods 2 508 can support the enclosure and serve as a railing. When full enclosure is not required for ventilation, the two first support rods 303, the second support rod 307, and the diamond-shaped bracket form a guardrail, thereby preventing the ingress of foreign objects and creating a barrier effect.

[0037] It is worth noting that the lighting device 4 includes a lifting pole 402, on which a light bulb 403 is mounted. The surface of the lifting pole 402 is slidably connected to the upper pull plate 1. The bottom of the lifting pole 402 is provided with an extrusion rod 401, which is mounted on a connecting rod 1 507. When the connecting rod 1 507 rotates, it will drive the rotation of the extrusion rod 401, and the center point of its rotation is connected to the upper pull plate 1. Therefore, when the upper pull plate 1 as a whole is raised, the "diamond frame" will be passively raised, so the connecting rod 1 507 will rotate, thereby squeezing and lifting the lifting pole 402, lifting the light bulb 403 out of the interior of the upper pull plate 1, thereby achieving the contraction and lifting of the light bulb 403, thereby avoiding the situation where the light bulb 403 is exposed too much and is squeezed and damaged during transportation and storage.

[0038] Furthermore, a battery is installed inside the upper pull plate 1, and a pull rope 404 is connected to the lifting pole 402. One end of the pull rope 404 is connected to a solar panel 405. The solar panel 405 is rotatably connected to the upper pull plate 1. When the light bulb 403 is raised, it will drive the pull rope 404 to rise, and then drive the solar panel 405 to rotate, thereby forming a flat state to receive solar light to the greatest extent. The height of the enclosure can also be adjusted according to the position of the sun's rays, thereby adjusting the angle of the solar panel to maximize the utilization rate of solar energy. The solar panel 405 can absorb light energy and convert it into electrical energy for storage, thereby providing power for various electrical components inside the enclosure, thereby achieving environmental protection and energy saving effects.

[0039] Furthermore, the dust suppression device 6 includes a connecting pipe 604, the bottom of the connecting pipe 604 is fixedly connected to a blade 606, and a box 608 is provided on the surface of the blade 606. When the water source enters the box 608, it will impact the blade 606 and drive it to rotate, and the connecting pipe 604 will automatically rotate. One side of the box 608 is connected to the water inlet pipe 601, and the other side of the box 608 is connected to the water outlet pipe 607. The box 608 is rotatably connected to the turntable 602, and the turntable 602 is connected to the turntable 602. There is a pipe 603, the other end of which is connected to a connecting pipe 604. A nozzle 605 is installed on the top of the connecting pipe 604. After the other part of the incoming water is resisted by the blades 606, it will enter the connecting pipe 604 from the position of the two pipes 603 and then enter the position of the nozzle 605. At this time, the nozzle 605 on the connecting pipe 604 will perform a rotary spray or water spray to achieve dust reduction in the surrounding area, improve the surrounding construction environment, and reduce the impact of construction on the surrounding environment. In addition, the rotary spray or water spray can flush the solar panel 405, warning light 503, and warning sign 504, thereby preventing dust adhesion caused by long-term storage and reducing the warning effect.

[0040] Working principle: First, the overall enclosure is a long box structure. After the operator places it in the installation position, he directly presses the pedal 71 to move the connecting plate 73 downward, thereby driving the connecting gear plate 301 downward. After that, the linear motion is converted into rotational motion through the meshing transmission between the gear and the gear plate, thereby driving the rotation of the first support rod 303. The rotation of the first support rod 303 will drive the relative rotation of the second gear 304, and the rotation of the second gear 304 will drive the meshing rotation of the third gear 305. The second support rod 307 is fixed to the third gear 307. 05, so at this time the second support rod 307 will rotate relative to each other, so that the first support rod 303 and the second support rod 307 will be stretched apart, and the upper pull plate 1 will be raised to form an integral enclosure. When it moves to a certain height, the operator will step on the bottom pin 722 of the foot rotating plate 721 and press it into the socket 723 opened on the lower base 2 to insert and fix it with a pin. Because the height of the connecting tooth plate 301 is different, the height of the overall enclosure will also be different. Therefore, multiple sockets 723 are set to cope with the fixation at different heights. When the entire device is raised, the diamond frame located in the middle part, that is, the two connecting rods 1 507 and the two connecting rods 2 508 form a bracket, which can provide a certain degree of support effect for the overall enclosure. After rising, the prompt rod 506 will also fall vertically, forming an "exclamation mark" sign, providing a construction warning to surrounding personnel. Taking into account the need for full shielding in some construction areas, a roller shutter-type pull-up tab 501 is provided. The pull-up tab 501 itself has a certain degree of bending elasticity, similar to the properties of a tape measure, and can be pulled up and automatically retracted. At this time, if full shielding is achieved, the operator can hang the two hanging rings 502 on the pull-up tab 501 on the hook of the second support rod 307 to achieve full shielding, and a warning light 503 and a sign 504 are provided on the pull-up tab 501 to provide warnings to passers-by in the surrounding area. During the night, the triangular sign formed by multiple warning lights 503 can provide warnings and illuminate the sign 504. The solar panel 405 can be deployed when the fence is raised, and can absorb sunlight during the day and convert it into electrical energy for storage, thereby providing lighting for the bulb 403 and operation of the warning light 503. And the whole equipment can be connected to the water pipe. When the operator connects the water pipe to the water inlet pipe 601, the water source will enter the box 608. The water pressure entering will drive the rotation of the blade 606, thereby driving the rotation of the entire connecting pipe 604. A part of the water source will enter the connecting pipe 604 from the position of the two pipes 603, and then enter the position of the nozzle 605. At this time, the nozzle 605 on the connecting pipe 604 will perform rotary spraying or water spraying to achieve dust reduction treatment in the surrounding area, improve the surrounding construction environment, and reduce the impact of construction on the surrounding environment.
