Description

Technical Field

[0001] This utility model relates to the field of concrete curing technology, specifically to a spray curing device for concrete buildings. Background Technology

[0002] Spray curing equipment for concrete structures is a specialized device that uses pipes, nozzles, and other components to atomize clean water and continuously or intermittently spray it onto concrete structures (such as beams, slabs, columns, walls, and pavements) during the hardening process. Its core function is to create and maintain a suitable temperature and humidity environment for the concrete, preventing drastic changes in ambient temperature and humidity from affecting the concrete's performance.

[0003] In existing technologies, some concrete building spray curing devices operate by spraying water through multiple nozzles on water pipes. However, if a single nozzle becomes clogged or damaged during spraying, the water supply must be stopped before the damaged or clogged nozzle can be replaced. This undoubtedly delays normal spraying operations, consumes additional maintenance and coordination time, reduces curing efficiency, and increases labor costs. Therefore, we propose a spray curing device for concrete buildings. Utility Model Content

[0004] The purpose of this utility model is to provide a spray curing device for concrete structures, in order to solve the problem mentioned in the background art that some spray curing devices for concrete structures use multiple nozzles on a water pipe for spraying. During the spraying operation, if a single nozzle is blocked or damaged, it is necessary to stop the water supply of the entire water pipe. This undoubtedly delays the normal spraying operation, consumes additional maintenance and coordination time, reduces curing efficiency, and increases labor costs.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a spray curing device for concrete structures, comprising: a water supply pipe, a docking seat fixedly connected to the top end of the water supply pipe, and a nozzle installed on the top end of the docking seat;

[0006] It also includes: two fixed brackets are fixedly connected to the outside of the docking seat, two rotating clips are rotatably connected to the outside of the nozzle, the two rotating clips engage with the two fixed brackets respectively, the two fixed brackets and the two rotating clips are symmetrical, a sealing diaphragm is fixedly connected inside the docking seat, a water outlet is opened inside the sealing diaphragm, a push spring is fixedly connected to the bottom of the inside of the water supply pipe, a sealing plate is fixedly connected to the top of the push spring, and a long rod is fixedly connected to the top of the sealing plate.

[0007] The top of the long rod contacts the bottom of the nozzle, and the outer side of the long rod is slidably connected to the inside of the water outlet.

[0008] The sealing plate is located directly below the water outlet, and the water outlet is located at the center of the sealing plate.

[0009] The water supply pipe has a telescopic rod 1 fixedly connected to its inner bottom end, and a telescopic rod 2 is slidably connected inside the telescopic rod 1.

[0010] The top end of telescopic rod two is fixedly connected to the bottom end of the sealing plate, and the push spring is sleeved on the outside of telescopic rod one.

[0011] The nozzle has a sealing groove at the bottom and a sealing ring is fixedly connected to the top of the docking seat. The outer side of the sealing ring is slidably connected to the inside of the sealing groove.

[0012] The top of the docking seat is fixedly connected to a rubber ring, and the bottom of the nozzle is in contact with the rubber ring. The rubber ring is in a compressed state and surrounds the inner wall of the sealing ring.

[0013] This utility model has at least the following beneficial effects:

[0023] 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.

[0024] Example 1

[0025] Please see Figures 1 to 7 This utility model provides a technical solution: a spray curing device for concrete structures, comprising: a water supply pipe 1, the core function of which is to transport the water source required for spray curing, providing the water flow foundation for the entire device, and serving as the main installation carrier, supporting core components such as the docking seat 2, the push spring 7, and the telescopic rod 10, ensuring the stable assembly and coordinated operation of each structure. The top end of the water supply pipe 1 is fixedly connected to the docking seat 2, which is a key intermediate structure connecting the water supply pipe 1 and the nozzle 3, playing a connecting role. Its outer side is used to fix the fixing bracket 4, and its top end is used to install the sealing ring 13 and the rubber ring 14. The inner side is used to fix the sealing partition 6 and open the water outlet 15, providing the installation benchmark and working space for each component. The top end of the docking seat 2 is equipped with the nozzle 3, the core function of which is to atomize or disperse the water flow transported by the water supply pipe 1 and spray it evenly onto the surface of the concrete structure to achieve the curing and moisturizing effect.

[0026] It also includes: two fixed brackets 4 are fixedly connected to the outer side of the docking seat 2. The fixed brackets 4 cooperate with the rotating clips 5 to form a detachable locking structure, which is used to stably fix the nozzle 3 on the top of the docking seat 2. Through locking and limiting, it is prevented that the water flow pressure during spraying will cause the nozzle 3 to fall off or shift, and at the same time facilitates subsequent disassembly and maintenance. Two rotating clips 5 are rotatably connected to the outer side of the nozzle 3. The rotating clips 5 can rotate around the outer side of the nozzle 3. By locking and separating with the fixed brackets 4, the nozzle 3 can be quickly installed and removed without additional tools. The two rotating clips 5 are respectively locked with the two fixed brackets 4. The two fixed brackets 4 and the two rotating clips 5 are symmetrical. A sealing partition 6 is fixedly connected inside the docking seat 2. The sealing partition 6 can interact with the sealing plate 8. In conjunction with the nozzle 3, the docking seat 2 can be sealed after the nozzle 3 is removed. The sealing partition 6 has an outlet 15 inside, which is designed to facilitate water discharge. The bottom of the water supply pipe 1 is fixedly connected to a push spring 7. The push spring 7 is normally in a compressed state, providing an upward thrust to the sealing plate 8, so that the sealing plate 8 can fit with the sealing partition 6 after the nozzle 3 is removed. The top of the push spring 7 is fixedly connected to the sealing plate 8, and the top of the sealing plate 8 is fixedly connected to a long rod 9. The long rod 9 plays a transmission linkage role. When the nozzle 3 is installed, its weight and the pressure of locking are transmitted to the sealing plate 8 through the long rod 9, pushing the sealing plate 8 to move down and open the water flow. When the nozzle 3 is removed, the long rod 9 loses pressure and moves up with the sealing plate 8 to reset under the action of the push spring 7.

[0027] The top of the long rod 9 contacts the bottom of the inside of the nozzle 3. The outer side of the long rod 9 is slidably connected to the inside of the outlet 15. When the nozzle 3 is installed, the weight and locking pressure of the long rod 9 are transmitted to the sealing plate 8 through the long rod 9, pushing the sealing plate 8 down to open the water flow. When the nozzle 3 is disassembled, the long rod 9 loses pressure and moves up with the sealing plate 8 to reset under the action of the pushing spring 7.

[0028] The sealing plate 8 is located directly below the water outlet 15, and the water outlet 15 is located at the center of the sealing partition 6. The fact that the sealing plate 8 is located directly below the water outlet 15 and the water outlet 15 is located at the center of the sealing partition 6 ensures that the sealing plate 8 can accurately seal the water outlet 15 on the partition 6.

[0029] A sealing groove 12 is provided at the bottom of the nozzle 3, and a sealing ring 13 is fixedly connected to the top of the docking seat 2. The outer side of the sealing ring 13 is slidably connected to the inside of the sealing groove 12. The sealing groove 12 and the sealing ring 13 of the docking seat 2 form a nested fit, which increases the sealing contact area at the connection between the nozzle 3 and the docking seat 2, prevents water from leaking from the gap at the connection, improves the sealing performance of the overall device, ensures that all water flows out from the nozzle 3, and improves the water resource utilization rate.

[0030] A rubber ring 14 is fixedly connected to the top of the docking seat 2. The bottom of the nozzle 3 is in contact with the rubber ring 14. The rubber ring 14 is in a compressed state and surrounds the inner wall of the sealing ring 13. The rubber ring 14 forms a second sealing barrier. Utilizing the elastic deformation characteristics of rubber, it tightly fits the bottom of the nozzle 3 and the top of the docking seat 2, further enhancing the sealing performance of the connection and preventing a small amount of water from leaking from the gap between the sealing ring 13 and the sealing groove 12.

[0031] The working principle of this spray maintenance device revolves around two core scenarios: from the installation of the nozzle 3 to the opening of the water flow and the sealing and leak prevention, and from the disassembly of the nozzle 3 to the automatic shut-off of the water flow and waterless maintenance. The various structures work together to achieve the core function of replacing the nozzle 3 without shutting off the water supply as a whole, which is divided into three stages.

[0032] When the nozzle 3 is clogged or damaged and needs to be replaced, press down on the nozzle 3 while rotating the rotating clip 5 in the opposite direction to separate it from the fixed bracket 4, releasing the fixing restriction on the nozzle 3. After removing the nozzle 3, the long rod 9 loses the downward pressure of the nozzle 3, pushing the spring 7 to release the compression potential energy and push the sealing plate 8 upward to reset. The sealing plate 8 moves vertically upward to directly below the water outlet 15 of the sealing partition 6, and fits tightly with the sealing partition 6, completely blocking the water outlet 15 and preventing water from leaking out of the water supply pipe 1. At this time, the water supply pipe 1 does not need to be shut down as a whole, and the disassembled nozzle 3 can be cleaned or replaced directly. After the replacement is completed, the spraying can be restored by reinstalling it to the start-up process, achieving rapid maintenance without water leakage.

[0033] By sealing the docking seat 2 where the individual nozzle 3 is located while maintaining and replacing it, waterless replacement of the nozzle 3 can be achieved without stopping the water supply of the entire water supply pipe 1, without delaying normal spraying operations and consuming additional maintenance coordination time, thereby improving maintenance efficiency and reducing labor costs.

[0034] Example 2

[0035] In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that a telescopic rod 10 is fixedly connected to the bottom of the water supply pipe 1. A telescopic rod 21 is slidably connected inside the telescopic rod 10. The telescopic rod 10 and the telescopic rod 21 cooperate with each other to provide a limit and support for the push spring 7, and can also connect the sealing sheet 8.

[0036] The top end of the telescopic rod 11 is fixedly connected to the bottom end of the sealing plate 8, and the push spring 7 is sleeved on the outside of the telescopic rod 10.
