Description

Technical Field

[0001] The present invention belongs to the field of building construction, and specifically relates to a spraying device for curing concrete during building construction. Background Art

[0002] During the construction process, after pouring concrete, it needs to be watered and cured for at least seven days in order to meet the various specified indicators of concrete. The concrete water spraying device is mainly used to spray water for curing concrete.

[0003] The Chinese patent with the publication number CN207402970U discloses a concrete curing spraying device, including a spray head and a spraying frame, the spraying frame is provided with a spraying conduit that can be lifted and lowered in the vertical direction, and pipe joints are provided at both ends of the spraying conduit, and the spraying frame is provided with an upper guide tube, a lower guide tube, a leg and a connecting rod; the upper guide tube is hinged to the upper end of the leg, and the two ends of the connecting rod are respectively hinged to the lower guide tube and the leg, and the spraying conduit passes through the upper guide tube and the lower guide tube in a sliding fit, and the lower guide tube adjusts the opening radius of the lower end of the leg when moving along the spraying conduit, and the upper guide tube and the lower guide tube are respectively provided with a set screw for fixing the spraying conduit. Although the device can achieve the purpose of curing concrete spraying, the height adjustment of the spraying device is relatively troublesome, the switch that controls the operation of the spraying device requires high production costs, and maintenance personnel are required to control the switch operation, and the entire device has a low degree of automation. Summary of the invention

[0004] The purpose of this scheme is to provide a spraying device for curing concrete with a high degree of automation.

[0005] In order to achieve the above-mentioned purpose, a spray device for curing concrete comprises a spray head, a telescopic rod and a base, wherein the telescopic rod is vertically fixed on the base, and the spray head is arranged on the telescopic rod; it also comprises a switch device for controlling the operation of the spray device, wherein the switch device comprises a fixed water pipe, a water pipe conversion joint, a water tank, a float, a gravity ball and an upper hollow water pipe for connecting the float and the gravity ball; the water pipe conversion joint is threadedly connected to the fixed water pipe, the water tank is fixedly arranged on the water pipe conversion joint, the float is arranged in the water tank, the upper end of the upper hollow water pipe is connected to the float and the other end is connected to the gravity ball, the upper hollow water pipe vertically passes through the water pipe conversion joint and is slidably arranged with the water pipe conversion joint, and the fixed water pipe is connected to the spray head.

[0006] The upper hollow water pipe described in this article refers to a water pipe with a hollow upper portion.

[0007] The principle of this scheme is: the nozzle is fixedly supported by a telescopic rod, the fixed water pipe is connected to the nozzle for water supply, and when the hollow part of the upper hollow water pipe is in the vertical pipe of the water pipe conversion joint, the water flow of the entire fixed water pipe circulates and supplies water to the nozzle, and the nozzle sprays water mist to maintain the concrete. When the nozzle sprays water mist, the water tank will slowly accumulate water. When the accumulated water in the water tank can make the float in the water tank float up, the upper hollow water pipe fixedly connected to the float and the gravity ball fixedly connected to the upper hollow water pipe will also move up due to the buoyancy. During the movement, the hollow part of the upper hollow water pipe moves out of the water pipe conversion joint, and the rest of the upper hollow water pipe blocks the pipe of the water pipe conversion joint. The water flow of the entire fixed water pipe stops flowing, and the nozzle stops working. The water in the water tank will evaporate in the air. When the water in the water tank evaporates to the point where the float cannot float on the water surface, the float sinks under the gravity of the gravity ball, and the upper hollow water pipe and the gravity ball sink. The hollow part of the upper hollow water pipe returns to the vertical pipe of the water pipe conversion joint again, and the water flows in the entire fixed water pipe. The nozzle sprays water mist again to cure the concrete. The water tank, float and gravity ball can realize timed, automatic and uniform spraying of water mist.

[0008] The beneficial effect of this solution is that by setting a water pipe conversion joint on a fixed water pipe, and setting a water tank, a float and a gravity ball on the water pipe conversion joint, the operation of the sprinkler can be controlled, acting as a switch. The sprinkler device of this solution can realize full-automatic concrete curing, does not require manual curing, and does not require additional expenses such as electricity, which can save a high cost for the enterprise.

[0009] Furthermore, the telescopic rod is provided with three sections in total. The arrangement of the three-section telescopic rod can adjust the height of the entire spray device and the spray range of the nozzle, thereby improving the practicality of the spray device.

[0010] Furthermore, the spray head is detachably connected to the fixed water pipe and the telescopic rod, which makes it more convenient to maintain and clean the entire device, making the use of the entire device more convenient.

[0011] Furthermore, the fixed water pipe is a plastic water pipe. Because the fixed water pipe is connected to the nozzle, the telescopic rod bears the weight of the fixed water pipe and the nozzle, and the water pipe made of plastic can reduce the weight borne by the telescopic rod. At the same time, the production cost of the plastic water pipe is lower, which is conducive to saving production costs.

[0012] Furthermore, the fixed water pipe is provided with two switch devices for controlling the operation of the spray device. The fixed water pipe is provided with two switch devices. Only when the hollow parts of the two upper hollow water pipes are simultaneously in the pipe of the water pipe conversion joint, the water flow of the entire fixed water pipe can flow, thereby starting the spray head to spray water mist. Such a dual setting can control the operation of the entire spray device more efficiently and accurately.

[0013] Furthermore, the base is a steel plate base, which can provide better stability and is durable. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following is a further detailed description through specific implementation methods:

[0021] The reference numerals in the drawings of the specification include: base 1, telescopic rod 2, nozzle 3, float 4, water tank 5, gravity ball 6, soft water pipe 7, upper hollow water pipe 8, water pipe conversion joint 9, fixed water pipe 10.

[0022] The embodiment is basically as shown in the attached Figure 1 As shown: the base 1 is a device for stabilizing the telescopic rod and the nozzle. The base 1 is made of steel. The steel plate is used because the steel plate itself has good hardness and long service life. The telescopic rod 2 is fixed on the base 1 and is located at the center of the base 1. The telescopic rod 2 is composed of three sections. The height of the telescopic rod 2 can be adjusted manually, so that the distance and range of the nozzle 3 spraying water can be adjusted accordingly. The specific number of sections of the telescopic rod 2 can also be adjusted according to needs. The telescopic rod is also made of steel, which makes it have good firmness and can bear the gravity of the nozzle and its fixed water pipe 10, and can also bear the impact caused by water pressure.

[0023] A connection hole for connecting the fixed water pipe 10 is also provided on the side of the spray head 3, through which the fixed water pipe 10 can supply water to the spray head 3. The spray head 3 is arranged on the top of the telescopic rod 2, and the spray head 3 and the fixed water pipe 10 and the telescopic rod 2 are connected in a detachable manner and can be replaced at any time, which is conducive to the maintenance, cleaning and replacement of the entire spray device. The fixed water pipe 10 is made of plastic, which is relatively light in weight, and can reduce the burden of the telescopic rod 2 to the greatest extent. At the same time, making it of plastic can also reduce the production cost.

[0024] The soft water pipe 7 is used as a water source, and a connector is provided on the other end of the fixed water pipe 10, through which the soft water pipe 7 can be connected to the fixed water pipe 10. The fixed water pipe 10 is provided with two water pipe conversion joints 9 at intervals by threaded connection. Figure 4 As shown, a water tank 5, a float 4, a gravity ball 6 and an upper hollow water pipe 8 connecting the float 4 and the gravity ball 6 are provided at each water pipe conversion joint 9. The water tank 5 is fixedly arranged on the water pipe conversion joint 9. The water tank 5 is in the shape of a funnel and is fixedly connected to the water pipe conversion joint 9. The float 4 is placed in the water tank 5. At the same time, the float 4 and the upper hollow water pipe 8 are fixedly connected. One end of the hollow part of the upper hollow water pipe 8 is connected to the float 4, and the other end is fixedly connected to the gravity ball 6. The upper hollow water pipe 8 is matched with the water pipe conversion joint 9. When the hollow parts of the two upper hollow water pipes 8 are in the pipeline of the water pipe conversion joint 9 at the same time, as shown in FIG. Figure 2 and Figure 5 As shown, the fixed water pipe 10 can be connected, and the nozzle 3 starts to spray water mist. At the same time, the water tank 5 located on the water pipe conversion joint 9 will slowly collect the sprayed water mist. When the water tank 5 collects a certain amount of water mist, the buoyancy of the float 4 can drive the upper hollow water pipe 8 and the gravity ball 6 to move upward together, and the hollow part of the upper hollow water pipe 8 extends out of the pipe of the water pipe conversion joint 9, and the lower end of the upper hollow water pipe 8 blocks the fixed water pipe 10. Figure 3 and Figure 6 As shown, the flow of water is blocked and the nozzle 3 stops working accordingly.

[0025] When it is necessary to start the nozzle 3 to spray water mist again, the water in the two water tanks 5 set on the water pipe conversion joint 9 needs to evaporate. When the water in the water tank 5 cannot make the float 4 float on the water surface, the float 4 moves downward as a whole under the gravity of the upper hollow water pipe 8 and the gravity ball 6, and the hollow part of the upper hollow water pipe 8 returns to the pipe of the water pipe conversion joint 9 again, and the fixed water pipe 10 is connected, and the nozzle 3 is started again to spray water mist. The whole device is provided with two water tanks 5, the float 4 and the gravity ball 6, which can play a dual effect of controlling the operation of the spray device. It can make the operation of the whole spray device more stable. By setting the depth and size of the water tank 5, the floating situation of the float 4 in the water tank 5 can be effectively controlled, and then the water flow situation of the fixed water pipe 10 can be determined, so as to control the time interval of the whole spray device spraying water mist. When the water tank 5 is relatively shallow, the water in the water tank 5 can evaporate quickly, and the float 4 can drive the upper hollow water pipe 8 and the gravity ball 6 to sink in a short time, thereby restarting the spray head 3. When the water tank 5 is relatively large and deep, it takes a long time for the accumulated water in the water tank 5 to evaporate before the float 4, the upper hollow water pipe 8 and the gravity ball 6 sink, thereby restarting the spray device to spray water mist.

[0026] Specific operation: When curing concrete, a spray device is set in a fixed area according to the actual situation of the site, and the soft water pipe 7 is connected to the fixed water pipe 10. At the beginning, the two floats 4 are located at the bottom of their respective water tanks 5, and the hollow parts of the upper hollow water pipes 8 connected to each other are also in the pipeline of the water pipe conversion joint 9, which conducts the fixed water pipe 10. Through the spraying of the nozzle 3, the water mist can be evenly sprayed on the concrete to achieve the purpose of curing concrete; at the same time, when the nozzle 3 sprays the water mist, water will accumulate in the water tank 5. When the water fills the water tank 5, the float 4 drives the upper hollow water pipe 8 and the gravity ball 6 connected thereto to move upward, so that the hollow part of the upper hollow water pipe 8 moves out of the pipeline of the water pipe conversion joint 9, and the rest of the upper hollow water pipe 8 blocks the water pipe conversion joint 9, hindering the flow of water, and the nozzle 3 stops working. When the water in the two water tanks 5 on the water pipe conversion joint 9 is evaporated at the same time, the float 4, the upper hollow water pipe 8 and the gravity ball 6 move downward. The hollow part of the upper hollow water pipe 8 returns to the pipe of the water pipe conversion joint 9 again, the fixed water pipe 10 is connected, and the nozzle 3 can continue to spray water mist. The spray device of this solution can realize fully automatic concrete curing, without the need for manual curing, and at the same time, does not require additional expenses such as electricity.

[0027] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
