Description

Technical Field

[0001] The present invention relates to a watering system for preventing heat stroke at construction sites and the like.

Background Art

[0002] In recent years, the average summer temperature has been rising. Therefore, technologies related to mist cooling devices have been developed to prevent heat stroke by attaching nozzles near gathering facilities and passageways, spraying water as mist from these nozzles, and utilizing the heat of vaporization of the mist to lower the ambient temperature (see, for example, Patent Document 1).

[0003] Also, at construction sites, technologies using this mist for dust prevention have attracted attention (see, for example, http: / / www.d-mist.com / case.html).

Summary of the Invention

Problems to be Solved by the Invention

[0005] Inside a construction site, during summer, work is often carried out in heat where the average temperature exceeds body temperature. Just spraying mist inside the site has a small preventive effect as a countermeasure against heat stroke for workers.

[0006] The present invention has been made in view of the above circumstances, and is for providing a watering system that can effectively cool the inside of a construction site even when the outside air temperature rises.

Means for Solving the Problems

[0007] To solve the above-mentioned problems, the watering system according to the present invention comprises a work platform provided to surround a building, a water supply hose arranged along the platform and supplied with water by a water supply means, and a watering means installed on top of the platform that sprays water from the connected water supply hose, switching between mist and filamentous water. Furthermore, the watering means can be connected to the water supply hose by a flexible hose, and the direction of the watering means can be changed by bending the flexible hose. [Effects of the Invention]

[0008] The watering system according to this invention allows for switching between spraying filamentous water on workers as needed, and compared to spraying mist, it can lower the workers' body temperature more effectively, thereby enabling more effective heatstroke prevention. Furthermore, the watering means is connected by a water supply hose and a flexible hose, and the direction of the shower head can be changed by bending the flexible hose, so that mist or filamentous water can be effectively sprayed according to the worker's work area. This enables more effective heatstroke prevention. [Brief explanation of the drawing]

[0009] [Figure 1] This is a schematic diagram of a construction site using a watering system according to an embodiment of the present invention. [Modes for carrying out the invention]

[0010] The watering system 10 according to an embodiment of the present invention will be described in detail below with reference to Figure 1. Figure 1 is an external view of a construction site equipped with the watering system 10.

[0011] At a construction site, a work scaffolding T is erected to surround the entire perimeter of a building 1 while it is under construction. This work scaffolding T consists of multiple vertical beams 2 spaced apart horizontally, and multiple horizontal beams 3 that connect these vertical beams 2 horizontally and are spaced apart vertically.

[0012] This building 1 includes, for example, ordinary houses, shops, and buildings, and encompasses all types of structures where construction work is carried out by erecting temporary scaffolding T around its perimeter. Furthermore, the scaffolding T also includes relatively large structures that cover the perimeter of building 1 with dustproof covers 4 (or privacy covers) and have footboards (not shown) for workers to stand on and perform tasks.

[0013] Multiple shower heads 30 (watering devices) are provided on the upper part of this work platform T. As shown in Figure 1, at least two of these shower heads 30 are arranged along the outer perimeter of the building 1, spaced apart in the left-right direction.

[0014] Furthermore, a water supply means 21 is provided on the outside of the work platform T. A water supply hose 20 (shown by a thick line in Figure 1) is connected to this water supply means 21 and multiple shower heads 30 (more precisely, flexible hoses 31 extending from the shower heads 30) so as to connect them to each other.

[0015] The water supply means 21 is supplied with tap water from a water pipe (not shown in the diagram). The water supply means 21 is also equipped with a valve that can be opened and closed manually or electrically. By opening and closing this valve, the flow rate and water pressure of the water supplied to the water supply hose 20 can be adjusted, and the supply can be started and stopped. Furthermore, the water supply means 21 may also be equipped with a pressure pump to pressurize the supplied water as needed.

[0016] In Figure 1, the water supply means 21 is positioned outside the work scaffolding T, but it may also be positioned inside the scaffolding or inside the building 1, depending on the location of the water pipes. Furthermore, if there are no water pipes, the water supply means 21 may be equipped with a water storage tank, and water stored in this tank may be pumped up to supply water.

[0017] As shown in Figure 1, the water supply hose 20 extends upward along the vertical beam 2 of the work scaffolding T and is positioned to surround the outer perimeter of the building 1 along the upper horizontal beam 3.

[0018] The showerhead 30 is designed to spray (jet) the supplied water in either a mist or filamentous stream 32. The filamentous stream 32 is a larger volume of water than the mist, and consists of multiple streams of water extending in a straight line (like a typical shower). Either the mist or the filamentous stream 32 can be switched manually or electrically. A commercially available showerhead 30 with this switchable function can be used. Furthermore, any showerhead capable of switching between these two states, even those not commercially available, can be used.

[0019] This showerhead 30 is positioned to spray (jet) from the work scaffolding T towards the inside of the building 1. Furthermore, by bending the flexible hose 31, it can be manually directed towards the scaffolding horizontally, or adjusted to direct the showerhead towards the outside of the building 1. This direction adjustment may also be performed by electrically rotating each part left or right using an electric motor or the like.

[0020] The switching between mist-like and filamentous water 32 from the showerhead 30 described above can be done manually, or by a signal from a control device (not shown) located within the water supply means 21. This control device and the showerhead 30 can be connected via radio waves such as Bluetooth®, which can transmit and receive signals, or they can be connected via a wire routed along the water supply hose 20.

[0021] For example, by using the timer function or clock function in the control device, it is possible to switch from the mist state to the filamentous water 32 at a predetermined time (for example, daytime from 12:00 to 14:00). Also, by providing a function for measuring the ambient temperature in the control device, it is possible to switch from the mist state to the filamentous water 32 when the threshold of a predetermined temperature (for example, 37 degrees or more) is exceeded.

[0022] Next, the operation of the watering system 10 according to the present invention will be described. At a construction site in summer, since the ambient temperature may become higher than the air temperature, the watering system 10 of the present invention is installed to prevent heat stroke of workers.

[0023] Normally, the worker sets the shower head 30 so that mist-like water is sprayed. Thereby, the ambient temperature is lowered by the heat of vaporization when the mist-like water vaporizes, and heat stroke can be prevented. However, when the air temperature further rises, it becomes difficult to sufficiently lower the temperature by simply continuing to spray the mist.

[0024] In that case, the worker operates the shower head 30 to switch from the mist state to the filamentous water 32. Since the filamentous water 32 has a larger amount of water compared to the mist, the ambient temperature can be further lowered by using the heat of vaporization. Also, when the worker is bathed in the filamentous water 32, an effect of wetting the body and lowering the body temperature can be obtained.

[0025] Also, when the watering system 10 of the present invention is used in a general customer attraction facility to let users bathe in filamentous water, it is conceivable that many complaints will occur from the users. However, during work at a construction site, even if the worker's work clothes get slightly wet, no problem will occur. Furthermore, if the immediate problem of heat stroke prevention can be solved, the worker will also use the watering system 10 after fully understanding it.

[0026] Furthermore, the shower head 30 sprays mist or filamentous water 23 towards workers working inside the building 1, but when working on scaffolding T, the direction of the shower head 30 is adjusted to face the scaffolding. This adjustment can be easily done by bending the flexible hose 31.

[0027] Furthermore, by using the control device within the water supply means 21 to pre-set operating time or temperature thresholds, it is possible to switch to spraying filamentous water 32 at a predetermined timing.

[0028] The watering system 10 of this invention includes a work platform T installed to surround a building 1, a water supply hose 20 arranged along the scaffolding T and supplied with water by a water supply means 21, and a shower head 30 installed on top of the scaffolding T that switches between spraying water from the connected water supply hose 20 as either a mist or filamentous water 23. Therefore, when necessary, the system can switch to spray filamentous water 23 on workers, which can lower the workers' body temperature more effectively compared to spraying mist, thereby enabling more effective heatstroke prevention.

[0029] Furthermore, the watering means 21 is connected by a water supply hose 20 and a flexible hose 31, and the direction of the shower head 30 can be changed by bending the flexible hose 31. This allows for the effective spraying of mist or filamentous water 32 according to the worker's work area. This enables more effective heatstroke prevention measures.

[0030] Although the watering system 10 according to an embodiment of the present invention has been described above, the present invention is not limited to the embodiments described above, and various modifications and changes are possible based on the technical concept of the present invention.

[0031] For example, in this embodiment, the shower head 30 is installed at the top of the scaffolding to spray mist or filamentous water 32 using gravity, but it may also be installed in the middle of the scaffolding T in the height direction. This makes it possible to take more effective measures against heatstroke according to the worker's work content and work location. Furthermore, although the showerhead 30 is normally directed towards the inside of the scaffolding T (towards the building 1), it may also be configured to spray the mist towards the outside of the scaffolding. This allows the entire construction site to be cooled using evaporative cooling. [Explanation of Symbols]
