Description

Technical Field

[0001] The present invention relates to the field of power station construction safety technology, and specifically to a power station construction protection laser curtain wall monitoring and alarm system, which aims to improve the safety and efficiency of the construction site, while ensuring that the alarm information is clear and visible, and can maintain a good warning effect even in an outdoor dusty environment. Background Art

[0002] In the field of safety protection of power station construction, laser curtain wall technology, as a cutting-edge solution, has significantly improved the safety and efficiency of construction sites. The core of the system is composed of a precision laser beam detector array, which is designed to monitor and protect key construction areas. In the complex construction environment of the power station, the laser curtain wall effectively blocks unauthorized entry and prevents potential safety risks. In addition, the integrated alarm system can immediately send an alarm signal to the control center when an abnormal situation is detected, and visually warn the intruder through sound or light signals (such as flashing lights), enhancing the immediate response capability of the site.

[0003] At present, the alarm communication methods of most laser curtain wall systems rely on sound alarms and visual warning lights. In particular, visual warnings usually use high-brightness warning lights. When the system is triggered, the lights are activated by the internal controller to attract the attention of people around with strong visual signals. However, in projects such as power station construction, which are often carried out in open and dusty environments, warning lights face severe challenges. Dust on the construction site is easy to accumulate on the warning light housing, which not only blocks the light, causing the brightness to decrease, reducing the visual distance, but also weakens its effectiveness as a safety warning. What's more serious is that the long-term accumulation of dirt may react adversely with the shell material of the warning light, accelerate the aging process of the material, shorten the service life of the equipment, and increase maintenance costs and replacement frequency.

[0004] Therefore, in view of the problem that laser curtain wall warning lights in power station construction environments are easily affected by dust and dirt, it is particularly important to develop more durable, pollution-resistant or self-cleaning warning devices to ensure the continuity and effectiveness of construction safety. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the above technical defects and provide a power station construction protection laser curtain wall monitoring and alarm system.

[0006] To solve the above technical problems, the present invention provides a laser curtain wall monitoring and alarm system for power station construction protection, including: a lamp base, inside which a controller is provided; a mounting block, arranged at the upper end of the lamp base, having an annular structure and an air outlet; a mounting post, mounted on the mounting block, with a lamp bead provided at its upper end, the lamp bead being electrically connected to a power source, and a cylindrical groove being opened at its lower end, and a fan blade capable of being driven by a motor being provided inside the cylindrical groove; an annular groove, opened on the outer side of the mounting post and partially communicating with the cylindrical groove; an annular plate, slidably connected in the annular groove, with a toothed block provided on its inner circle; a gear ring, rotatably connected in the cylindrical groove and meshing with the toothed block of the annular plate, and the outer side of the gear ring being connected to the output shaft of the motor through a belt; a lamp cover, movably mounted on the outer side of the mounting post; a cleaning mechanism, including a connecting member and a cleaning strip provided on the connecting member, the connecting member being connected to the annular plate, and the cleaning strip being used to clean the outer wall of the lamp cover as the annular plate rotates.

[0007] Preferably, the connecting member is an arc-shaped plate, its lower end being connected to the outer side of the annular plate, its upper end being rotatably connected to the upper end of the lamp cover, the inner side of the arc-shaped plate being made of a reflective material, and the cleaning strip being provided on one side of the inner wall of the arc-shaped plate and contacting the outer side of the lamp cover.

[0008] Preferably, the upper end of the cleaning strip is connected to the upper end of the arc-shaped plate, and the remaining part of the cleaning strip is slidably connected to the inner wall of the arc-shaped plate.

[0009] Preferably, the connecting member is an explosion-proof grille, which is sleeved on the outer side of the lamp cover and its lower end is connected to the annular plate, and the cleaning strip is provided inside the explosion-proof grille and contacts the outer side of the lamp cover.

[0010] Preferably, the connecting member includes an explosion-proof grille part and an arc-shaped part connected to the inner side of the explosion-proof grille part, the explosion-proof grille part being sleeved on the outer side of the lamp cover and its lower end being connected to the annular plate, the inner side of the arc-shaped part being made of a reflective material, and the cleaning strip being provided on one side of the inner wall of the arc-shaped part and contacting the outer side of the lamp cover.

[0011] Preferably, the upper end of the cleaning strip is connected to the upper end of the arc-shaped part, and the remaining part of the cleaning strip is slidably connected to the inner wall of the arc-shaped part.

[0012] Preferably, annular mounting grooves are opened on both sides of the upper end of the mounting post, and two arc-shaped grooves communicating with the annular mounting grooves are evenly opened at the upper end of the mounting post. Arc-shaped convex blocks adapted to the arc-shaped grooves are oppositely provided on the inner wall of the lower side of the lamp cover. The arc-shaped convex blocks can first be embedded into the arc-shaped grooves, and then the lamp cover is rotated to make the arc-shaped convex blocks enter the annular mounting grooves to achieve fixation.

[0013] Preferably, an annular embedding groove is opened on the outer side of the mounting post, and a sealing rubber tube is provided in the embedding groove;

[0014] A plurality of sliding grooves are provided on the arc-shaped groove. The lower ends of the sliding grooves are communicated with a sealing rubber tube through an air inlet pipe. A multi-stage airbag telescopic tube is hermetically and slidably connected inside the sliding groove.

[0016] The power station construction protection laser curtain wall monitoring and alarm system provided by this application effectively solves the problem that the warning lights of the laser curtain wall in the power station construction environment are easily affected by dust and dirt through the ingeniously designed cleaning mechanism. The cleaning mechanism can automatically clean the outer wall of the lamp cover as the annular plate rotates, not only keeping the lamp cover clean, but also improving the brightness and attention-grabbing effect of the warning light. In addition, the design of the cleaning mechanism is flexible and diverse, which can be in the form of an arc-shaped plate cooperating with a cleaning strip, or in the form of an explosion-proof grille, or combining the advantages of both, providing both additional mechanical protection and ensuring the cleaning effect.

[0017] At the same time, the lamp cover installation method in this application is also innovative. Through the cooperation of the arc-shaped convex block with the arc-shaped groove and the annular mounting groove, the rapid installation and disassembly of the lamp cover are realized, which is convenient for the maintenance and repair of the warning light. In addition, the design of the multi-stage airbag telescopic tube and the sealing rubber tube further improves the sealing effect of the lamp cover, effectively preventing external dust and water from entering the inside of the lamp cover, thereby extending the service life of the warning light.

[0018] In summary, through a series of innovative designs, this application not only improves the safety and reliability of the laser curtain wall monitoring and alarm system, but also reduces the maintenance cost and replacement frequency, providing a strong guarantee for the safety protection of power station construction. At the same time, the design idea of this application also provides new solutions and ideas for safety protection problems in other similar scenarios. Description of the Drawings

[0033] Embodiment 1

[0034] Combined with the attached Figure 1 、attached Figure 2 、attached Figure 4 and attached Figure 9, a laser curtain monitoring and alarm system for power station construction protection, comprising: a lamp holder 1, inside which a controller is arranged; a mounting block 11, arranged at the upper end of the lamp holder 1, being an annular structure and having an air outlet; a mounting post 12, mounted on the mounting block 11, with a lamp bead arranged at its upper end, the lamp bead being electrically connected to a power source, and a cylindrical groove 13 being opened at its lower end, and a fan blade 131 capable of being driven by a motor being arranged inside the cylindrical groove 13; an annular groove 14, opened on the outer side of the mounting post 12 and being partially communicated with the cylindrical groove 13; an annular plate 141, slidably connected in the annular groove 14, and having a toothed block on its inner circle; a gear ring 132, rotatably connected in the cylindrical groove 13 and meshing with the toothed block of the annular plate 141, and the outer side of the gear ring 132 being connected to the output shaft of the motor through a belt; a lamp cover 15, movably mounted on the outer side of the mounting post 12; a cleaning mechanism 2, which comprises a connecting piece and a cleaning strip 22 arranged on the connecting piece, the connecting piece being connected to the annular plate 141, and the cleaning strip 22 being used for cleaning the outer wall of the lamp cover 15 as the annular plate 141 rotates.

[0035] In this embodiment, the connecting piece is an arc-shaped plate 21, its lower end is connected to the outer side of the annular plate 141, and its upper end is rotatably connected to the upper end of the lamp cover 15. The inner side of the arc-shaped plate 21 is made of a reflective material, and the cleaning strip 22 is arranged on one side of the inner wall of the arc-shaped plate 21 and contacts the outer side of the lamp cover 15; such that the upper end of the cleaning strip 22 is mounted on the upper end of the arc-shaped plate 21, the rest of the cleaning strip 22 is slidably connected to the inner wall of the arc-shaped plate 21, and in the initial state, the cleaning strip 22 is located at the side of the arc-shaped plate 21 and not in the middle of the arc-shaped plate 21; such that when the annular plate 141 rotates, the arc-shaped plate 21 rotates, the arc-shaped plate 21 drives the cleaning strip 22 to rotate, the cleaning strip 22 is made of an elastic material, when the arc-shaped plate 21 starts to rotate, the cleaning strip 22 cleans the inner wall of the lamp cover 15, and because there is friction between the cleaning strip 22 and the lamp cover 15, and the lower side of the cleaning strip 22 is not fixed, so when the arc-shaped plate 21 starts to rotate, the lower end of the cleaning strip 22 will deflect inside the arc-shaped plate 21 and slide along the inner wall of the arc-shaped plate 21, playing a role in cleaning the reflective layer on the inner wall of the arc-shaped plate 21 during the process, improving its reflective effect, and further improving the brightness and attention-grabbing effect of the warning lamp; subsequently, as the arc-shaped plate 21 continues to rotate, the cleaning strip 22 plays a role in cleaning the lamp cover 15; when the arc-shaped plate 21 does not rotate, the cleaning strip 22 is automatically reset under the action of its own elasticity.

[0036] Furthermore, the upper end of the cleaning strip 22 is connected to the upper end of the arc-shaped plate 21, and the rest of the cleaning strip 22 is slidably connected to the inner wall of the arc-shaped plate 21. When installing the warning light, first install the mounting post 12 on the mounting block 11. The mounting block 11 is circularly arranged, and the mounting post 12 is cylindrical, so that the mounting post 12 is embedded in the annular inner circle of the mounting block 11, and then it is fixed with screws or the like; after the installation is completed, the motor, the fan and the gear ring 132 etc. arranged inside the cylindrical groove 13 opened at the lower end of the mounting post 12 are located inside the cylindrical groove 13; then the lamp cover 15 is installed on the upper end of the mounting post 12, and the lamp cover 15 seals the lamp beads at its upper end, and the lamp beads are electrically connected to the power supply;

[0037] When the warning light is in use, the motor inside it rotates. When the motor rotates, it drives the fan blade 131 to rotate. The fan blade 131 discharges the gas inside the warning light, and the outside gas enters the inside of the cylindrical groove 13 through the air inlet, realizing heat dissipation inside it;

[0038] And an annular groove 14 is opened on the outer side of the mounting post 12, and an annular plate 141 is slidably connected inside the annular groove 14. An annular groove 142 is opened in the inner circle of the annular plate 141, and a tooth block is arranged inside the annular groove 142. An annular belt groove 133 is opened on the outer side of the gear ring 132; a belt is sleeved inside the belt groove 133, and the other end of the belt is sleeved on the output shaft of the motor. During the process of the motor driving the fan blade 131 to rotate, the output shaft of the motor drives the belt to rotate, and the other end of the belt is sleeved on the gear ring 132, so that the belt drives the gear ring 132 to rotate. During the rotation of the gear ring 132, one side of the gear passes through the communication part between the cylindrical groove 13 and the annular groove 14, and the gear meshes with the tooth block on the inner side of the annular plate 141; so that the gear ring 132 drives the annular plate 141 to rotate. When the annular plate 141 rotates, the cleaning mechanism arranged on the outer side of the annular plate 141 rotates along with the annular plate 141. The cleaning mechanism includes an arc-shaped plate 21. The arc-shaped plate 21 is arranged on the outer side of the annular plate 141, and the upper end is rotatably connected to the upper end of the lamp cover 15, so that during the rotation of the annular plate 141, it will drive the arc-shaped plate 21 to move in a circular motion around the lamp cover 15. During the process, the cleaning strip 22 arranged on the inner side of the arc-shaped plate 21 contacts the outer wall of the lamp cover 15, so that the cleaning strip 22 cleans the outer wall of the lamp cover 15, avoiding the problems of dust accumulation on its outer wall and affecting the light transmittance of the lamp cover 15; and the inner side of the arc-shaped plate 21 is made of a reflective material (by laying an aluminum material on the surface of the arc-shaped plate 21). When the warning light is on, the arc-shaped plate 21 moves in a circular motion around the lamp cover 15, making the warning light show an intermittent flashing effect, which is more attention-grabbing. And the inner wall of the arc-shaped plate 21 is made of a reflective material, further improving the brightness of the warning light and enhancing the warning effect.

[0039] Embodiment 2

[0040] The difference between Example 2 and Example 1 is that Example 2 is a supplementary description of the cleaning mechanism 2 in Example 1. Specifically, it can exist as an alternative embodiment of the cleaning mechanism in Example 1. How to produce and install it can be selected according to needs.

[0041] In this embodiment, the connecting piece is an explosion-proof grille, which is sleeved outside the lamp shade 15 and its lower end is connected to the annular plate 141. The cleaning strip 22 is arranged inside the explosion-proof grille and contacts the outside of the lamp shade 15.

[0042] When the cleaning mechanism is an explosion-proof grille, the explosion-proof grille provides additional mechanical protection for the outer ring of the warning light, preventing the lamp shade 15 of the warning light from being damaged when subjected to external force impact or collision outdoors, thereby protecting the electrical components inside the warning light. As the annular plate 141 rotates, during the rotation process of the annular plate 141, the explosion-proof grille is driven to rotate, and the cleaning strip 22 arranged inside the explosion-proof grille contacts the outer wall of the lamp shade 15, realizing the cleaning of the outer wall of the lamp shade 15; thus playing a role in keeping the outer wall of the lamp shade 15 clean, improving the brightness of the warning light, and further improving the warning effect.

[0043] Example 3

[0044] Combined with the attached Figure 3 , the difference between Example 3 and Example 1 and Example 2 is that this embodiment is a combination of Example 1 and Example 2 and can exist as an alternative embodiment of the cleaning mechanism in Example 1 and Example 2;

[0045] In this embodiment, the connecting piece includes an explosion-proof grille part 23 and an arc part 24 connected to the inside of the explosion-proof grille part 23. The explosion-proof grille part 23 is sleeved outside the lamp shade 15 and its lower end is connected to the annular plate 141. The inner side of the arc part 24 is made of a reflective material, and the cleaning strip 22 is arranged on one side of the inner wall of the arc part 24 and contacts the outside of the lamp shade 15. On the basis of the above Example 1 and Example 2, when the annular plate 141 rotates, the annular plate 141 drives the explosion-proof grille part 23 to rotate. During the rotation process of the explosion-proof grille part 23, the arc part 24 and the cleaning strip 22 inside it are driven to rotate. During the process, the cleaning strip 22 cleans the outer wall of the lamp shade 15, keeping the outer wall of the lamp shade 15 clean and improving the brightness of the warning light; improving the warning effect; and the reflective material on the inner side of the arc part 24 and the arc part 24 itself make the warning light have an intermittent flashing effect, thereby improving the warning effect; and the explosion-proof grille part 23 also plays a protective effect on the lamp shade 15, thereby improving the service life of the warning light.

[0046] In this embodiment, the upper end of the cleaning strip 22 is connected to the upper end of the arc portion 24, and the rest of the cleaning strip 22 is slidably connected to the inner wall of the arc portion 24. The upper end of the cleaning strip 22 is mounted on the upper end of the arc portion 24, and the rest of the cleaning strip 22 is slidably connected to the inner wall of the arc portion 24. And in the initial state, the cleaning strip 22 is located on the side of the arc portion 24 and not in the middle of the arc portion 24. When the annular plate 141 rotates, the arc portion 24 rotates, and the arc portion 24 drives the cleaning strip 22 to rotate. The cleaning strip 22 is made of an elastic material. When the arc portion 24 starts to rotate, the cleaning strip 22 cleans the inner wall of the lamp cover 15. And because there is friction between the cleaning strip 22 and the lamp cover 15, and the lower side of the cleaning strip 22 is not fixed, so when the arc portion 24 starts to rotate, the lower end of the cleaning strip 22 will deflect inside the arc portion 24 and slide along the inner wall of the arc portion 24, playing a role in cleaning the reflective layer on the inner wall of the arc portion 24 during the process, improving its reflective effect, and thus improving the brightness and attention-grabbing effect of the warning lamp. Subsequently, when the arc portion 24 continues to rotate, the cleaning strip 22 plays a role in cleaning the lamp cover 15. When the arc portion 24 does not rotate, the cleaning strip 22 is automatically reset under the action of its own elasticity.

[0047] Embodiment 4

[0048] Combined with the attached Figure 5 - attached Figure 8 In this embodiment, annular mounting grooves 121 are provided on both sides of the upper end of the mounting post 12, and two arc grooves 122 communicating with the annular mounting grooves 121 are evenly provided at the upper end of the mounting post 12. Arc-shaped convex blocks 151 adapted to the arc grooves 122 are provided on the opposite inner walls of the lower side of the lamp cover 15. The arc-shaped convex blocks 151 can first be inserted into the arc grooves 122, and then the lamp cover 15 is rotated to make the arc-shaped convex blocks 151 enter the annular mounting grooves 121 to achieve fixation.

[0049] In this embodiment, an annular embedding groove 126 is provided on the outer side of the mounting post 12, and a sealing rubber tube 127 is provided in the embedding groove 126;

[0050] A plurality of sliding grooves 124 are provided on the arc groove 122. The lower ends of the sliding grooves 124 are communicated with the sealing rubber tube 127 through an air inlet pipe. A multi-stage airbag expansion tube 125 is hermetically and slidably connected inside the sliding groove 124. When the arc-shaped convex block 151 is inserted into the arc groove 122, the multi-stage airbag expansion tube 125 can be squeezed, and the gas in the multi-stage airbag expansion tube 125 enters the sealing rubber tube 127 through the air inlet pipe, so that the sealing rubber tube 127 expands and tightly adheres to the inner wall of the lamp cover 15;

[0051] A sliding plate 123 is also slidably provided in the annular mounting groove 121. When the arc-shaped convex block 151 enters the inside of the annular mounting groove 121, it can squeeze the sliding plate 123. Under the squeezing action of the arc-shaped convex block 151, the sliding plate 123 enters the inside of the arc-shaped groove 122 and limits the upper end of the multi-stage airbag telescopic tube 125.

[0052] An annular mounting groove 121 is formed on the outer side of the upper end of the mounting post 12. The arc-shaped grooves 122 uniformly arranged at the upper end of the mounting post 12 communicate with the annular mounting groove 121. At the same time, arc-shaped convex blocks 151 are uniformly arranged on the inner wall of the lower side of the lamp cover 15. When installing the lamp cover 15, just align the arc-shaped convex blocks 151 on the inner side of the lamp cover 15 with the arc-shaped grooves 122, and then embed the arc-shaped convex blocks 151 into the inside of the arc-shaped grooves 122. Then rotate the lamp cover 15, and the arc-shaped convex blocks 151 enter the inside of the annular groove 14, thereby fixing the lamp cover 15, making the installation of the lamp cover 15 simple and more convenient for disassembling and overhauling the warning lamp.

[0053] During the installation process of the lamp cover 15, a sliding groove 124 is formed on the bottom wall of the arc-shaped groove 122. A multi-stage airbag telescopic tube 125 is hermetically slidably connected inside the sliding groove 124. An annular embedding groove 126 is formed on the outer side of the mounting post 12. A sealing rubber tube 127 is installed inside the embedding groove 126. The air inlet pipe on the sealing rubber tube 127 is connected to the lower end of the sliding groove 124. When installing the lamp cover 15, the arc-shaped convex blocks 151 on the inner side of the lamp cover 15 squeeze the upper end of the multi-stage airbag telescopic tube 125. After being squeezed, the multi-stage airbag telescopic tube 125 moves downward inside the sliding groove 124. During this process, the gas in the sliding groove 124 enters the inside of the sealing rubber tube 127, causing the sealing rubber tube 127 to expand and squeeze the inner wall of the lamp cover 15, improving the sealing effect. Then rotate the lamp cover 15, and the arc-shaped convex blocks 151 enter the inside of the annular mounting groove 121, squeezing the sliding plate 123 slidably connected inside the annular mounting groove 121. The sliding plate 123 enters the inside of the arc-shaped groove 122, and then limits the upper end of the multi-stage airbag telescopic tube 125, preventing the multi-stage airbag telescopic tube 125 from resetting upward after the arc-shaped convex blocks 151 enter the annular mounting groove 121, thereby improving the sealing effect of the lamp cover 15 and preventing external dust and water from entering the inside of the lamp cover 15, and improving the service life of the warning lamp.

[0054] The above describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative work without departing from the purpose of the present invention, they shall fall within the protection scope of the present invention.
