Description

Technical Field

[0001] The present invention relates to the technical field of fences, in particular to a safety protection device for construction and civil engineering. Background Art

[0002] The reflective portion of the warning sign utilizes the retro-reflective properties of high-refractive glass beads and the reflective properties of the micro-diamond-shaped reflective lattice, using an advanced focusing post-processing process. It reflects direct light from a distance back to its source, exhibiting excellent retro-reflective optical properties both day and night. At night, it offers the same high visibility as during the day. Warning signs made with this high-visibility reflective material are easily spotted by nighttime drivers, regardless of distance or interference from bright or scattered light.

[0003] A publicly disclosed safety protection device for construction and civil engineering (Announcement No. CN116717136B) includes a protective plate fixedly connected to a plurality of vertically arranged hollow tubes arranged in a linear array. Two opposing guide plates are positioned above the hollow tubes, arranged in a V-shape with the lower ends adjacent to each other. Vertically arranged drive rods are slidably connected to both sides of the protective plate. The lower ends of the two guide plates are rotatably connected to the upper ends of the drive rods. Drive blocks are fixedly connected to the outer sides of the two guide plates, and the upper ends of the drive blocks abut against the guide plates. This safety protection device for construction and civil engineering, through the hollow tubes mounted on the protective plate, allows construction waste to be added to the hollow tubes to increase the weight and enhance the stability of the device. The drive rods can also be used to control the lower ends of the hollow tubes to open and discharge the material, facilitating repeated use of the device.

[0004] However, in the above application, it is difficult to convey the traffic information that this is a construction site to the outside world with low visibility, and in the existing technology, warning alarms are issued through flashing warnings of various electronic components, which is cumbersome to operate manually. It is difficult to avoid excessive damage to electronic components caused by rain erosion, and it cannot meet the problem of lightweight design during the disassembly and assembly of the fence. Therefore, a safety protection device for construction and civil engineering is proposed to solve the above problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a safety protection device for construction and civil engineering in view of the deficiencies in the above-mentioned prior art.

[0006] To solve the above technical problems, the present invention adopts a technical solution: a safety protection device for construction and civil engineering, comprising a hollow seat, the top of which is bolted to a fence body, the top of which is fixedly connected to a fence, and a side of the fence body provided with an adaptive change warning device; the adaptive change warning device comprises a support rod, the side of which is fixedly connected to a safety warning sign, the side of which is fixedly connected to a warning glass color-changing cover, the top of the safety warning sign having a natural rainwater outlet, the bottom of the safety warning sign having a curved support drain rod fixedly connected, the side of the curved support drain rod having a drainage hole, the top of the warning glass color-changing cover provided with a litmus discharge device, the top of the litmus discharge device having a litmus solvent tank, the side of the litmus solvent tank having a connecting and fixing rod fixedly connected, the bottom of the connecting and fixing rod fixedly connected to the top of the natural rainwater outlet. The adaptive change warning device collects rainwater through the natural rainwater outlet, triggering the litmus discharge device to release litmus solvent into the warning glass color-changing cover. When the pH value of rainwater is abnormal (such as acid rain), the litmus test reagent mixes with the rainwater and changes color. The warning signal is visually displayed through the warning glass, realizing automatic monitoring and visual alarm of environmental changes, and providing real-time feedback on the surrounding environmental conditions without human intervention.

[0007] Preferably, the litmus blanking equipment includes a connecting pipe, one end of the connecting pipe is fixedly connected to the top of the safety warning sign, the outer surface of the connecting pipe is fixedly connected to a middle connecting pipe, one end of the connecting pipe is provided with a first blanking port, one end of the middle connecting pipe is fixedly connected to a transfer pipe, and the outer surface of the transfer pipe is fixedly connected to a protective shell.

[0008] Preferably, the litmus discharge equipment also includes a semi-arc blocking rod, the bottom of the semi-arc blocking rod is slidably connected to one end of the first discharge port, one end of the semi-arc blocking rod is fixedly connected to a connecting rod, one end of the connecting rod passes through the side of the middle pipe, and the end of the connecting rod close to the middle pipe is fixedly connected to a control panel, one end of the control panel passes through the side of the protective shell, and the end of the control panel close to the protective shell is provided with a discharge control device.

[0009] Preferably, the material discharge control device includes an arc-shaped pneumatic chamber, one end of which is fixedly connected to the side of the safety warning sign, one end of which is internally slidably connected to piston plate 1, and the other end of which is internally slidably connected to piston plate 2, one end of which is fixedly connected to a control panel. The material discharge control device utilizes piston plates 1 and 2 within the arc-shaped pneumatic chamber to transmit rainwater pressure, pushing the control panel to drive the semi-arc blocking rod to open the first material discharge port. This design achieves low-threshold triggering through the principles of fluid mechanics.

[0010] Preferably, a return spring is fixedly connected to the side of the control panel, one end of which is fixedly connected to a spring fixing plate, one end of which is fixedly connected to the side of the middle pipe. The return spring on the side of the control panel resets the control panel through the drainage port provided on the side of the arc-shaped air pressure chamber after the rain stops draining, thereby driving the semi-arc-shaped blocking rod to close the first discharge port.

[0011] Preferably, a metering adaptive adjustment device is provided at one end of the connecting pipe close to the first discharge port, and the metering adaptive adjustment device includes a symmetrical arc block, the two symmetrical arc blocks are fixedly connected to the inner wall of the first discharge port, the side of the symmetrical arc block is slidably connected to an adaptive arc block, the side of the adaptive arc block is provided with a flow regulating port, the side of the symmetrical arc block is provided with an adaptor regulating port, and the inside of the transfer pipe is fixedly connected with a booster pump. In the metering adaptive adjustment device, the symmetrical arc block and the adaptive arc block form a variable flow channel. When the rainfall is heavy, the booster pump is started, and the impact force pushes the adaptive arc block to compress the tension spring, so that the overlapping area of ​​the flow regulating port and the adaptor regulating port is increased, releasing more litmus solvent; when the rainfall is small, the tension spring resets to shrink the flow channel, realizing dynamic matching of "rainfall-discharge amount", avoiding reagent waste, and improving the endurance of the device.

[0012] Preferably, one end of the adaptive arc block is fixedly connected to a tension spring, which is also fixedly connected to one end of the symmetrical arc block. The adaptive arc block returns to its initial position under the action of the tension spring. This design enables the device to be repeatedly triggered, allowing it to operate continuously during multiple rainfall events, reducing maintenance costs.

[0013] Preferably, the top of the adaptive arc block is located directly below the transfer tube, and the side of the adaptive arc block is slidably connected to the inner wall of the connecting tube. The top of the adaptive arc block is higher than the top of the symmetrical arc block. This design increases the stable operation capability of the equipment.

[0014] Preferably, the natural rainwater outlet is connected to the warning glass color change cover, and the flow regulating port and the adapter regulating port are located at the same horizontal line. Such a design is conducive to directly displaying the color change of the solution after the reaction in the natural rainwater outlet through the warning glass color change cover.

[0015] The present invention adopts the above technical solution, which can bring the following beneficial effects: 1. This safety protection device for building and civil engineering projects uses an adaptive warning device design to adjust the pH value of rainwater to an acidic level. The mixture of litmus reagent and rainwater changes color, resulting in a red color. This red warning effect, combined with the shape of the warning glass color-changing cover, provides a warning effect. The warning glass color-changing cover then conveys traffic information about the construction site to outsiders in areas with low visibility. Compared to existing technologies that rely on flashing warning electronic components, this device reduces manual operation and avoids excessive wear of electronic components caused by rainwater erosion, achieving a lightweight design during the fence assembly and disassembly process.

[0016] The safety protection device for building civil engineering adopts the design of the internal discharge control device of the adaptive change warning device, so that the semi-arc blocking rod is displaced so that the top of the first discharge port is no longer blocked by the semi-arc blocking rod, thereby opening the first discharge port, and the litmus reagent inside the litmus solvent box will flow through the middle pipe through the transfer pipe and merge into one end of the connecting pipe. At this time, the first discharge port has been opened, allowing the litmus reagent to flow into the safety warning sign through the connecting pipe and merge with the rainwater inside the safety warning sign. The warning signal is intuitively displayed through the warning glass, realizing automatic monitoring and visual alarm of environmental changes, and providing real-time feedback on the surrounding environmental conditions without human intervention.

[0017] This safety protection device for building civil engineering is designed in collaboration with metering adaptive adjustment equipment, so that the adaptive arc block slides vertically downward, causing the flow adjustment port and the adaptation adjustment port opened on the side to coincide with each other. Litmus reagent flows in through the flow adjustment port opened at one end of the top of the adaptive arc block, and is then discharged into the adaptation adjustment port through the other end of the flow adjustment port. Finally, it is discharged from one end of the adaptation adjustment port opened at the bottom of the symmetrical arc block into the interior of the safety warning sign, thereby increasing the color display effect of the safety warning sign and thus having better warning capabilities.

[0020] 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.

[0021] See also Figure 1 Figure 7One embodiment of the present invention is: a safety protection device for construction and civil engineering, comprising a hollow seat 1, the top of the hollow seat 1 is bolted to a fence body 2, the top of the fence body 2 is fixedly connected to a fence 3, and the side of the fence body 2 is provided with an adaptive change warning device 4; the adaptive change warning device 4 comprises a support rod 41, the side of the support rod 41 is fixedly connected to a safety warning sign 42, the side of the safety warning sign 42 is fixedly connected to a warning glass color-changing cover 43, the top of the safety warning sign 42 is provided with a natural rainwater outlet 44, the bottom of the safety warning sign 42 is fixedly connected to an arc-shaped support drainage rod 45, the side of the arc-shaped support drainage rod 45 is provided with a drainage hole 46, the top of the warning glass color-changing cover 43 is provided with a litmus discharge device 47, the top of the litmus discharge device 47 is provided with a litmus solvent box 48, the side of the litmus solvent box 48 is fixedly connected to a connecting and fixing rod 49, and the bottom of the connecting and fixing rod 49 is fixedly connected to the top of the natural rainwater outlet 44. Adaptive change warning device 4 collects rainwater through a natural rainwater outlet 44, triggering litmus dispensing device 47 to release litmus solvent into warning glass color-changing cover 43. Rainwater has an acidic pH value, and the litmus solvent mixes with the rainwater, causing a color change. The warning signal is visually displayed on the warning glass, enabling automatic monitoring of environmental changes and visual alarms, providing real-time feedback on surrounding environmental conditions without manual intervention.

[0022] The litmus feeding device 47 includes a connecting pipe 471, one end of which is fixedly connected to the top of the safety warning sign 42, and the outer surface of the connecting pipe 471 is fixedly connected to the middle connecting pipe 472. A first feeding port 473 is opened at one end of the connecting pipe 471, and one end of the middle connecting pipe 472 is fixedly connected to the transfer pipe 474, and the outer surface of the transfer pipe 474 is fixedly connected to the protective shell 475.

[0023] The litmus discharge device 47 also includes a semi-arc blocking rod 476, the bottom of the semi-arc blocking rod 476 is slidably connected to one end of the first discharge port 473, and one end of the semi-arc blocking rod 476 is fixedly connected to a connecting rod 478, one end of the connecting rod 478 passes through the side of the middle connecting pipe 472, and the end of the connecting rod 478 close to the middle connecting pipe 472 is fixedly connected to a control panel 479, one end of the control panel 479 passes through the side of the protective shell 475, and the end of the control panel 479 close to the protective shell 475 is provided with a discharge control device 477.

[0024] The material discharge control device 477 comprises an arc-shaped air pressure chamber 4771, one end of which is fixedly connected to the side of the safety warning sign 42. A piston plate 1 4772 is slidably connected to one end of the arc-shaped air pressure chamber 4771, and a piston plate 2 4773 is slidably connected to the other end of the arc-shaped air pressure chamber 4771. One end of the piston plate 2 4773 is fixedly connected to the control panel 479. The material discharge control device 477 utilizes the piston plates 1 4772 and 2 4773 within the arc-shaped air pressure chamber 4771 to transmit rainwater pressure, pushing the control panel 479 and driving the semi-arc-shaped blocking rod 476 to open the first material discharge port 473. This design utilizes the principles of fluid mechanics to achieve a low-threshold trigger.

[0025] A return spring 4774 is fixedly connected to the side of the control plate 479. One end of the return spring 4774 is fixedly connected to a spring retaining plate 4775. One end of the spring retaining plate 4775 is fixedly connected to the side of the middle pipe 472. After the rainwater stops draining, the return spring 4774 on the side of the control plate 479 is reset by the control plate 479 through the drainage port provided on the side of the arc-shaped air pressure chamber 4771, driving the semi-arc-shaped blocking rod 476 to close the first discharge port 473.

[0026] Working principle: When installing the protective device, first place a thick cement layer in the installation area, insert the hollow seat 1 into the cement layer to secure the base. Then, bolt the hollow seat 1 to the fence body 2. Then, pour cement through the filling hole above the hollow seat 1 to mix with the cement layer inside the hollow seat 1. After cooling, reinforce the fence body 2 to ensure the fixed installation of the protective device. In order to warn vehicles to slow down at the construction site during rainy weather, when it rains at the construction site, the visibility of vehicles is reduced due to low visibility. At this time, rainwater flows into the interior of the safety warning sign 42 through the natural rainwater outlet 44. Since the safety warning sign 42 is connected to the warning glass color-changing cover 43, the rainwater will flow into the interior of the warning glass color-changing cover 43 after filling the safety warning sign 42. At the same time, some rainwater enters the interior of the arc-shaped air pressure chamber 4771 through the gap at the top of the arc-shaped air pressure chamber 4771. The interior of the arc-shaped air pressure chamber 4771 is subjected to an increasing pressure according to the amount of rainfall. When the rainfall is heavy, the pressure inside the arc-shaped air pressure chamber 4771 increases. At this time, the elastic potential energy of the reset spring 4774 cannot offset the pressure of the rainfall on the interior of the arc-shaped air pressure chamber 4771. The piston plate 1 4772 compresses the gas inside the arc-shaped air pressure chamber 4771 to slide toward one end of the piston plate 2 4773, thereby driving the piston plate 2 4773 to compress the reset spring 4774 and extend it toward the outside of one end of the arc-shaped air pressure chamber 4771. The extension of the piston plate 2 4773 drives the control plate 479 to move horizontally. The horizontal displacement of the control panel 479 drives the horizontal displacement of the connecting rod 478, which drives the horizontal displacement of the semi-arc blocking rod 476. The displacement of the semi-arc blocking rod 476 makes the top of the first discharge port 473 no longer blocked by the semi-arc blocking rod 476, thereby opening the first discharge port 473. The litmus reagent inside the litmus solvent box 48 will flow through the intermediate pipe 472 through the transfer pipe 474 and merge into one end of the connecting pipe 471. At this time, the first discharge port 473 is open, allowing the litmus reagent to flow into the safety warning sign 42 through the connecting pipe 471 and merge with the rainwater inside the safety warning sign 42. Since the rainwater dissolves carbon dioxide in the air to produce carbonic acid and other substances, it is acidic. When the litmus reagent merges with the rainwater, it turns red. The red warning effect, combined with the warning shape design of the warning glass color-changing cover 43, conveys the traffic information of the construction site to the outside world with low visibility through the warning glass color-changing cover 43.

[0027] See also Figure 1 - Figure 7 In another embodiment of the present invention, based on the above embodiment, a metering adaptive adjustment device 5 is installed at one end of the connecting tube 471 near the first discharge port 473. The metering adaptive adjustment device 5 comprises symmetrical curved blocks 51. Two symmetrical curved blocks 51 are fixedly connected to the inner wall of the first discharge port 473. Adaptive curved blocks 52 are slidably connected to the sides of the symmetrical curved blocks 51. The sides of the adaptive curved blocks 52 are provided with flow control ports 53, and the sides of the symmetrical curved blocks 51 are provided with adaptable adjustment ports 54. A booster pump is fixedly connected to the interior of the transfer tube 474. In the metering adaptive adjustment device 5, the symmetrical curved blocks 51 and the adaptive curved blocks 52 form a variable flow channel. When rainfall is heavy, the booster pump is activated, and the impact force pushes the adaptive curved blocks 52 to compress the tension spring 55, increasing the overlapping area between the flow control port 53 and the adaptable adjustment port 54, releasing more litmus solvent. When rainfall is light, the tension spring 55 returns to its original position, narrowing the flow channel. This achieves dynamic matching between rainfall and discharge volume, avoiding reagent waste and improving the device's endurance.

[0028] One end of the adaptive arc block 52 is fixedly connected to a tension spring 55, which is also fixedly connected to one end of the symmetrical arc block 51. The adaptive arc block 52 returns to its initial position under the action of the tension spring 55. This design enables the device to be repeatedly triggered, allowing it to continue operating during multiple rainfall events and reducing maintenance costs.

[0029] The top of the adaptive arc block 52 is located directly below the transfer tube 474, and the side of the adaptive arc block 52 is slidably connected to the inner wall of the connecting tube 471. The top of the adaptive arc block 52 is higher than the top of the symmetrical arc block 51. This design increases the stable operation capability of the equipment.

[0030] The natural rainwater outlet 44 is connected to the warning glass color change cover 43, and the flow regulating port 53 is located at the same horizontal line as the adapter regulating port 54. This design is conducive to directly displaying the color change of the solution after the reaction in the natural rainwater outlet 44 through the warning glass color change cover 43.

[0031] Working principle: When the rainfall is heavy, the booster pump inside the transfer tube 474 can be started to extract the litmus reagent inside the transfer tube 474 to increase the internal pressure of the transfer tube 474 and thus increase the reagent flow rate. At this time, the adaptive arc block 52 compresses the tension spring 55 when the pressure in the transfer tube 474 increases, and slides vertically downward under the restriction of the symmetrical arc block 51. The adaptive arc block 52 slides vertically downward, so that the flow regulating port 53 and the adaptation regulating port 54 opened on the side coincide with each other. The litmus reagent flows in through the flow regulating port 53 opened at one end of the top of the adaptive arc block 52, and is then discharged to the inside of the adaptation regulating port 54 through the other end of the flow regulating port 53, and finally is discharged from one end of the adaptation regulating port 54 opened at the bottom of the symmetrical arc block 51 to the inside of the safety warning sign 42, so as to increase the color display effect of the safety warning sign 42, thereby having better warning capabilities.

[0032] The present invention provides a safety protection device for construction and civil engineering. There are numerous methods and approaches for implementing this technical solution. The foregoing description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the present invention. Any components not specified in this embodiment may be implemented using existing technologies.
