Description

Technical Field

[0001] This utility model relates to the field of civil engineering maintenance equipment, and in particular to a bridge pier maintenance device. Background Technology

[0002] After concrete is poured, the water in the concrete evaporates too quickly, causing dehydration. This prevents the cement particles, which have already formed a gel, from fully hydrating and transforming into stable crystals, resulting in insufficient bonding strength. Consequently, flaking or powdering occurs on the concrete surface. Premature evaporation of water before the concrete has sufficient strength can also cause significant shrinkage deformation and drying shrinkage cracks. Therefore, post-concrete curing is crucial. To address this, utility model application number 202122417864.1 discloses a concrete spray curing device. A gear moves and rotates simultaneously with the concrete structure, driving a connecting block to rotate. The water pipe moves up and down while rotating, allowing for uniform spraying of higher concrete structures without the need for continuous manual spraying, thus ensuring construction quality. This technical solution requires installation around bridge piers to automatically and uniformly spray the civil engineering pavement and pier structures based on air dust content and humidity without human monitoring, reducing manpower and unnecessary resource waste. However, this solution is not comprehensive enough for all bridge piers, potentially leaving some areas unsprayed, affecting the actual effect. Utility Model Content

[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0032] Reference Figures 1 to 4 The bridge pier maintenance device of this utility model includes a bridge pier body 100, a water tank 200, a fixed spray head 300, and a movable spray head 400. Slide rails 110 are provided at the curved positions on both sides of the bridge pier body 100, extending along the side edges of the bridge pier body 100. The water tank 200 is fixed to the bottom of the bridge pier body 100 and has two first water outlets and two second water outlets. The fixed spray heads 300 are located on the bridge pier body 100. At the upper ends of both sides, the spraying area of ​​the fixed spray head 300 covers at least 1 / 2 of the surface of the pier body 100. A first water pipe 210 is connected between the fixed spray head 300 and the first water outlet. The movable spray head 400 is slidably connected to the slide rail 110. A second water pipe 220 is connected between the movable spray head 400 and the second water outlet. The first water pipe 210 is concealed within the pier body 100, and the second water pipe 220 is a flexible hose and is located on the outside of the pier body 100.

[0033] During use, water from the water tank 200 enters the fixed spray head 300 through the first outlet and is sprayed onto the upper surface of the pier body 100. The two fixed spray heads 300 on both sides work together to cover the entire pier body 100 with water. Some water from the fixed spray heads 300 spills onto the edges of the pier body 100, further spraying the entire pier body 100. Simultaneously, water from the water tank 200 enters the movable spray head 400 through the second outlet and is sprayed out. The movable spray head 400 slides along the slide rail 110, spraying water directly onto the curved sides of the pier body 100, compensating for areas not covered by the fixed spray heads 300. This ensures the entire pier body 100 is covered with water, improving the spray coverage effect.

[0034] In summary, the fixed sprinkler head 300 provides stable spraying and curing to the surface of the pier body 100, while the movable sprinkler heads 400 located on both sides of the pier body 100 can move and spray and cure areas on both sides of the pier body 100 that are difficult to spray, thereby improving the uniformity of spraying and ensuring the quality of the building.

[0035] Specifically, in order to deliver water from the water tank 200 to the fixed spray head 300 and the movable spray head 400, both the first water pipe 210 and the second water pipe 220 are equipped with high-pressure water pumps 700 for pumping water.

[0036] In addition, refer to Figure 4 The bridge pier maintenance device also includes a dust sensor 500 and a controller 600. The controller 600 is connected to a high-pressure water pump 700 to control the start and stop of the high-pressure water pump 700. The controller 600 and the dust sensor 500 are electrically connected. The dust sensor 500 detects the dust level around the entire bridge pier body 100 in real time. If the threshold is reached, the controller 600 drives the high-pressure water pump 700 to supply water to the first water pipe 210 and the second water pipe 220.

[0037] In some embodiments, reference Figure 3 To improve the spraying effect, a small-hole nozzle 310 is integrally formed on the upper end of the fixed spray head 300, and the inner diameter of the upper end of the fixed spray head gradually decreases. This increases the pressure when the water is sprayed, causing the water to form a water mist and expanding the coverage area. In addition, to further expand the coverage area, an umbrella-shaped diffuser 320 is installed on the upper end of the fixed spray head 300, and multiple spray holes 321 are spaced apart on the edge of the diffuser 320.

[0038] In some embodiments, reference Figure 2 The movable sprinkler head 400 includes a movable block 410 and a spray gun 420. The movable block 410 is slidably connected to the slide rail 110. The spray gun 420 is mounted on the movable block 410 and is inclined towards the side wall of the pier body 100. The spray gun 420 is connected to a second water pipe 220, with the spraying end of the spray gun 420 facing upwards. This allows the water sprayed from the spray gun 420 to directly spray onto the side of the pier body 100.

[0039] Preferably, the spray gun 420 is rotatably mounted on the movable block 410, and the spray gun 420 can rotate around a fixed center. This ensures that the spraying range of the spray gun 420 can cover the width of the entire side of the pier body 100, thereby ensuring the uniformity of the spraying. With the vertical plane as the center, the rotation angle of the spray gun 420 to the left and right is less than 90°, and the slide rail 110 is located at the center of the side of the pier body 100. Figure 2The dotted line indicates the position where the spray gun 420 can rotate, which improves the uniformity of water spraying to both sides when the spray gun 420 sprays water to both sides.

[0040] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
