Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a water-saving concrete wall spray curing device. Background Technology

[0002] Concrete curing is a key measure to ensure the quality and service life of concrete. It involves artificially creating certain humidity and temperature conditions to allow freshly poured concrete to harden normally and increase in strength.

[0003] Spray curing is an important method of concrete curing, mainly used to keep the concrete surface moist to promote cement hydration, reduce crack formation, and ensure the strength development of the concrete.

[0004] Spray curing typically involves workers directly spraying water onto the wall using a tap to keep it moist. The water sprayed onto the concrete wall falls off quickly, so continuous spraying is needed to achieve the desired curing effect. However, this process results in significant water waste.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Example 1 See Figures 1 to 3 This utility model provides a water-saving concrete wall spray curing device, including a wheeled cart 1, a water receiving tray 2 located at the lower part of the cart 1, a water collection unit 3 on the water receiving tray 2, a water pump 4 on the frame of the cart 1, the water inlet end of the water pump 4 is connected to the water inlet pipe 5, and the lower end of the water inlet pipe 5 extends into the water receiving tray 2. The water pump 4 has an outlet pipe 6 at its outlet end. A three-way valve is installed on the pipe body of the outlet pipe 6. Two of the three ports are connected to the outlet pipe 6, and the other port is connected to an external water source. A spray pipe 7 is connected to the outlet pipe 6. The spray pipe 7 is T-shaped. One end of the spray pipe 7 is a handheld part. Several nozzles 8 are installed on the horizontal part that is perpendicular to the handheld part.

[0021] The operator pushes the wheeled cart 1 to move the water-saving concrete wall spray curing device to the concrete wall to be sprayed and cured, and adjusts the parking position of the cart 1 so that the water collection unit 3 is close to the wall. The operator adjusts the three-way valve on the water outlet pipe 6 and switches the valve to the "external water source connected" state, so that the port of the three-way valve connected to the external water source is unobstructed with the water outlet pipe 6. After the external water source enters the water outlet pipe 6 through the three-way valve, it flows to the spray pipe 7 connected to it. The operator holds the handpiece of the spray pipe 7 and sprays water evenly onto the concrete wall surface with the nozzle 8 to start the wall spray curing operation. During the spraying process, the water sprayed onto the concrete wall flows naturally downwards along the wall surface and eventually all flows into the water collection tray 2 at the bottom of the handcart 1. The water collection unit 3 on the water collection tray 2 collects the returning spray water to prevent the water from spilling onto the ground.

[0022] Before the water in the receiving pan 2 reaches its full capacity, the operator adjusts the three-way valve again to disconnect the external water source from the outlet pipe 6, so that the outlet pipe 6 forms a complete water flow channel. Then, the water pump 4 is started. The water pump 4 draws the recycled water collected in the receiving pan 2 through the inlet pipe 5 connected to the inlet end. After being pressurized by the water pump 4, the recycled water is transported from the outlet end of the water pump 4 to the outlet pipe 6, and then flows through the outlet pipe 6 to the spray pipe 7. Finally, the spray nozzle 8 continues to spray and cure the wall until the curing work of the entire concrete wall is completed.

[0023] The water collection unit 3 includes a water collection plate 9 fixedly installed on the water receiving tray 2, and an extension plate 10 is detachably installed on each side of the water collection plate 9. Each expansion plate 10 is detachably connected to the water collection plate 9 by two locking pins 11; Both the water collection plate 9 and the extension plate 10 have V-shaped cross sections. A drain outlet 12 is provided in the middle of the water collection plate 9, and the drain outlet 12 extends into the water receiving tray 2.

[0024] The operator attaches the two expansion plates 10 to the two sides of the water collection plate 9 respectively, and then uses the locking pins 11 to detachably connect and fix the expansion plates 10 to the water collection plate 9, thereby increasing the overall coverage width of the water collection unit 3, reducing the number of times the handcart 1 is moved, and improving the efficiency of construction. After maintenance, if the device needs to be moved, the extension plate 10 can be removed from the water collection plate 9 and carried with the device to reduce the space occupied by the device and facilitate the movement of the trolley 1 and the storage and transportation of the device.

[0025] The water collection plate 9 is generally low in the middle and high at both ends, forming a slope that allows the water on the water collection plate 9 and the expansion plate 10 to flow quickly towards the low middle area.

[0026] Locking pin 11 includes a mounting base 13 fixedly mounted on the expansion plate 10, a pin 14 rotatably mounted on the mounting base 13, a handle 15 fixedly mounted at one end of the pin 14 away from the water collection plate 9, and a limit block 16 fixedly mounted at the other end. A side plate 17 is fixedly installed at each of the two ends of the water collection plate 9. Two slots 18 are opened on the side plate 17, and each slot 18 corresponds to a set of locking pins 11.

[0027] When the extension plate 10 needs to be installed, the operator first attaches the extension plate 10 to the corresponding side of the water collection plate 9, aligns the locking pin 11 on the extension plate 10 with the slot 18 on the end side plate 17 of the water collection plate 9, and allows the limiting block 16 to pass through the slot 18 on the side plate 17. After the limiting block 16 has completely passed through the slot 18, the operator turns the handle 15 to drive the pin 14 to rotate, so that the orientation of the limiting block 16 and the slot 18 is staggered. At this time, the limiting block 16 is attached to the inner side of the side plate 17. Through the cooperation of the mounting base 13 and the side plate 17, the extension plate 10 is firmly fixed on the water collection plate 9.

[0028] The locking pin 11 can be fixed and removed simply by turning the handle 15, without the need for additional tools. The operation steps are simple and intuitive, and operators can quickly install or remove the expansion plate 10.

[0029] A hook 19 is provided above the handcart 1, and the water pipe 6 is wrapped around the hook 19.

[0030] By setting a hook 19 on the top of the handcart 1 and wrapping the water outlet pipe 6 around it, the water outlet pipe 6 can be stored in an orderly manner, preventing the water outlet pipe 6 from being scattered and dragged on the ground when the device is moved or idle, preventing the pipes from getting tangled and knotted, ensuring that the water outlet pipe 6 remains in a neat state, and making it easy to retrieve it quickly later.

[0031] A filter 20 is installed on the water inlet pipe 5.

[0032] The filter 20 can filter the return water drawn from the water receiving pan 2, effectively intercepting impurities such as concrete residue, dust, and sand that may be present in the water, preventing impurities from entering the water pump 4 with the water flow or clogging the nozzle 8 through the water outlet pipe 6, extending the service life of the device, and improving the overall operating economy of the equipment.

[0033] When using this utility model, push the wheeled trolley 1 to the wall to be cured, install the extension plate 10, and unplug the water pipe 6 on the hook 19; connect the three-way valve to the external water source, and the operator holds the spray pipe 7 and sprays the wall with the hand. Excess water flows down the wall and into the water collection tray 2 through the water collection unit 3. After the water tray 2 is full, switch the three-way valve to form a complete water flow channel in the outlet pipe 6. Then start the water pump 4. The water pump 4 draws the recycled water collected in the water tray 2 through the inlet pipe 5 connected to the inlet end. After being pressurized by the water pump 4, the recycled water is transported from the outlet end of the water pump 4 to the outlet pipe 6, and then flows through the outlet pipe 6 to the spray pipe 7. Finally, the spray nozzle 8 continues to spray and cure the wall until the curing work of the entire concrete wall is completed.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
