[0002] Bridge deck concrete curing is a crucial step in ensuring the performance and durability of bridge deck concrete. Curing can effectively control the temperature difference between the inside and outside of the concrete, reducing cracks caused by temperature stress. At the same time, it keeps the concrete surface moist, preventing shrinkage cracks caused by excessive evaporation of water, and improving the integrity and durability of the bridge deck. However, the existing bridge deck concrete curing equipment cannot quickly adjust the spray volume during spraying, which is inconvenient to use.

[0003] As disclosed in announcement number CN218203883U, a bridge deck concrete curing device for bridge construction includes a water spray pipe, a main connecting block, an insertion connecting block, a sealing spring, a sealing slider, and a post-welded block. The main connecting block is adapted to the sealing slider, and the main connecting block connects to the sealing slider. The sealing slider slides inside the main connecting block. The rear of the main connecting block has a slider connection port, and the front of the sealing slider is adapted to the slider connection port. The main connecting block has short-range sealing blocks and long-range positioning slides inside. The long-range positioning slides are arranged on the left and right sides inside the main connecting block, and the short-range sealing blocks are arranged on the upper and lower sides inside the main connecting block. The side of the sealing slider has a multi-functional connecting groove. The multi-functional connecting grooves on the upper and lower sides of the sealing slider are adapted to the short-range sealing blocks, and the multi-functional connecting grooves on the left and right sides of the sealing slider are adapted to the long-range positioning slides. Although this concrete curing device improves the sealing performance during use, it cannot adjust the spray volume during spray curing. Therefore, a bridge deck concrete curing device with adjustable spray volume is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a bridge deck concrete curing device with adjustable spray volume to solve the problems mentioned in the background art.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-7 In this embodiment of the invention, a bridge deck concrete curing device with adjustable spray volume includes:

[0026] The spray volume adjustment seat 1 has a built-in cavity 11, and the spray volume adjustment seat 1 is respectively provided with a water inlet pipe 2 and a connecting pipe 3;

[0027] The adjusting gear 4 and the driving gear 5 are installed in the built-in cavity 11. The adjusting gear 4 and the driving gear 5 mesh with each other. The adjusting gear 4 has several holes 41 of different diameters. During the process of adjusting the spray volume, the driving gear 5 is rotated, which drives the adjusting gear 4 that meshes with it to rotate.

[0028] Specifically, the inlet pipe 2 and the connecting pipe 3 are both fixedly connected to the spray volume adjustment seat 1, and the inlet pipe 2 and the connecting pipe 3 are concentrically arranged to facilitate the smooth flow of spray water from the inlet pipe 2 through the spray adjustment seat 1 into the interior of the connecting pipe 3. A sealing groove 6 is provided at the end of the inlet pipe 2 and the connecting pipe 3 where they pass into the built-in cavity 11. A sealing ring 7 is installed in the sealing groove 6, and the sealing ring 7 maintains contact with the adjusting gear 4. This prevents water in the inlet pipe 2 from leaking into the interior cavity 11 during the process of entering the connecting pipe 3. The built-in cavity 11 provides space for the adjusting gear 4 and the drive gear 5, preventing them from being exposed to the outside and easily interfered with during spraying. Both the adjusting gear 4 and the drive gear 5 are connected to the spray volume adjustment seat 1 via a rotating shaft. Both the adjusting gear 4 and the drive gear 5 can rotate around the shaft. The adjusting gear 4 and the drive gear 5 mesh, and the transmission ratio between the adjusting gear 4 and the drive gear 5 is not limited and can be adjusted according to… In practice, gears with different transmission ratios can be freely selected. The adjusting gear 4 has several holes 41, which are evenly distributed circumferentially with equal spacing between adjacent holes 41. One hole 41 is a fully enclosed structure, and the diameters of the remaining holes 41 decrease sequentially from large to small along the circumferential direction. The number of holes 41 is not limited. In this embodiment, preferably, there are five holes 41, which are evenly distributed. The transmission ratio between the adjusting gear 4 and the driving gear 5 is 5:1, that is, when the driving gear 5 rotates one revolution, the adjusting gear 4 rotates exactly the distance of one hole 41. This allows the holes 41 to be accurately aligned with the inlet pipe 2 and the connecting pipe 3 in sequence. This design ensures that each hole 41 can smoothly correspond to the water flow channel, ensuring that the water flows smoothly through the holes 41 into the interior of the connecting pipe 3. When holes 41 of different diameters are located between the inlet pipe 2 and the connecting pipe 3, the water flow rate is different, thus achieving different spray volume effects.

[0029] Please see Figure 4 In one embodiment, preferably, the spray volume adjustment seat 1 is provided with a first connecting hole 12 and a second connecting hole 13 that communicate with the built-in cavity 11. The first connecting hole 12 is connected to the water inlet pipe 2, and the second connecting hole 13 is connected to the connecting pipe 3. The inner diameter of the first connecting hole 12 is adapted to the outer diameter of the water inlet pipe 2 to ensure the sealing of the connection. The inner diameter of the second connecting hole 13 is adapted to the outer diameter of the connecting pipe 3 to ensure the sealing of the connection. A fixed base 8 is installed at the end of the water inlet pipe 2 away from the spray volume adjustment seat 1, and a water inlet 9 is installed on the water inlet pipe 2 near the fixed base 8. The end of the connecting pipe 3 away from the spray volume adjustment seat 1 is a threaded end, and a spray head is installed at the threaded end of the connecting pipe 3. The spray head and the connecting pipe 3 are connected by a thread, which facilitates the subsequent disassembly and assembly of the spray head.

[0030] Please see Figure 1-2In one embodiment, preferably, it further includes a stepper motor 10 mounted on the spray volume adjustment seat 1, the output end of the stepper motor 10 being connected to the drive gear 5; the output end of the stepper motor 10 is inserted into the built-in cavity 11, and the output end of the stepper motor 10 is connected to the spray volume adjustment seat 1 by an oil seal, which can prevent water from being discharged through the connection, and the output end of the stepper motor 10 is fixedly connected to the drive gear 5.

[0031] The working principle and usage process of this utility model are as follows: In the initial state, the fully enclosed hole 41 is concentrically set with the water inlet pipe 2 and the connecting pipe 3. At this time, the water flow cannot enter the connecting pipe 3 through the hole 41. When it is necessary to spray the concrete on the bridge surface, the stepper motor 10 is turned on to drive the drive gear 5 to rotate. Each rotation of the drive gear 5 adjusts the spacing of the gear 4 by exactly one hole 41. At this time, the fully enclosed hole 41 is transformed into holes 41 with different diameters. Then, according to the site conditions, the hole 41 is adjusted to correspond to the spray volume, so that the hole 41 is concentrically set with the water inlet pipe 2 and the connecting pipe 3, thereby adjusting the spray volume of the spray head.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0033] Therefore, the above description is only a preferred embodiment of this application and is not intended to limit the scope of this application; that is, all equivalent modifications made in accordance with the scope of the claims of this application shall be within the protection scope of the claims of this application.
