Description

[Technical field]

[0001] The present invention relates to a fluid distribution unit for distributing fluid at height. [Background technology]

[0002] It is desirable to spray water from a high place as a measure against heat stroke, and for rooftop greening and cooling. In addition, at construction sites, in addition to measures against heat stroke, dust is generated, so a method of spraying water or other fluids to make the dust fall is used out of consideration for the surrounding environment.

[0003] For example, Patent Document 1 describes an automatic watering method for demolishing a structure, in which panels equipped with direct injection nozzles that spray water in a straight line and spray nozzles that disperse water in a mist are provided at the top of scaffolding set up around the building, and guide rails are provided on the scaffolding to raise and lower the panels. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 3840174 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the automatic water sprinkling method for dismantling structures described in Patent Document 1, the panels are provided with direct injection nozzles and spray nozzles, and direct injection connecting pipes and spray connecting pipes that supply water to the direct injection nozzles and spray nozzles are also installed, so the panels themselves are heavy, and it is difficult to attach them to the guide rails and to connect the panels together. Moreover, to prevent heatstroke and falling dust, etc., workers must perform this work at a high altitude, and handling heavy objects at a high altitude is undesirable from a safety standpoint.

[0006] The present invention has been made in consideration of the above-mentioned problems, and its main object is to provide a fluid spraying unit that can safely spray fluid at high altitudes. [Means for solving the problem]

[0007] The fluid spraying unit of the present invention is for spraying fluid at high altitudes, and comprises a first pipe having a first flow path formed therein and extending vertically, a second pipe having a second flow path formed therein and extending horizontally, and having at least one fluid outlet for spraying fluid, and a connecting fitting provided on the first pipe to detachably connect the second pipe, and having a third flow path formed therein that connects the first flow path and the second flow path.

[0008] With the above-mentioned configuration, one end of the first pipe extending vertically is placed at a low position, and the other end is connected to the second pipe installed at a high position via a connecting joint, so that the fluid can be supplied from one end of the first pipe at a low position to the second pipe. Therefore, the worker can safely spray the fluid from a low position. In addition, since the fluid spraying unit of the present invention is composed of only three parts, the first pipe, the second pipe, and the connecting joint, it can be easily installed and can be used for various purposes such as heat stroke prevention, rooftop greening and cooling, dust prevention, and concrete curing.

[0009] In one embodiment of the fluid spraying unit of the present invention, the second piping comprises a piping main body having the second flow path formed therein and extending horizontally, and a spraying joint having the fluid outlet and connected to the piping main body, and having a spraying flow path formed therein for flowing fluid from the second flow path to the fluid outlet, and a coupler is provided at the connection end of the piping main body and the spraying joint.

[0010] With this configuration, the second pipe is constructed by connecting the pipe body and the spray joint, so that by adjusting the number of connected pipe bodies and spray joints, the horizontal length of the second pipe can be adjusted, and optimal fluid spraying can be performed according to the work location. In addition, since couplers are provided at the connection ends of the pipe body and the spray joint, workers can easily connect the pipe body and the spray joint, and the safety of the workers can be improved even when assembling the second pipe at a high place.

[0011] One aspect of the fluid spray unit of the present invention is one further comprising an adjustment mechanism provided on the spray joint for adjusting the spray direction of the fluid outlet.

[0012] With this configuration, the fluid outlet can be adjusted to the direction in which the fluid is to be sprayed, thereby increasing the efficiency of fluid spraying.

[0013] As an embodiment of the fluid spray unit of the present invention, there may be mentioned one further comprising an electromagnetic valve for opening and closing the third flow path and a controller terminal connected to the electromagnetic valve via a network and controlling the electromagnetic valve. Also, as an embodiment of the fluid spray unit of the present invention, there may be mentioned one in which the controller terminal comprises a transmitter for transmitting an opening / closing signal for opening and closing the electromagnetic valve, and a control unit for creating the opening / closing signal based on an external operation or a predetermined threshold value.

[0014] With this configuration, a solenoid valve that opens and closes the third flow path is provided, and a controller terminal that controls the solenoid valve is provided, so that the worker can remotely operate it and it becomes possible to spray fluid at high places without people present, further improving the safety of the worker. In addition, if the control unit of the controller terminal creates an opening and closing signal when a certain threshold is exceeded, such as the outside temperature exceeding 35°C, or when a certain time has passed, automatic spraying can be performed, which can also help to alleviate the labor shortage that has become an issue in various industries in recent years. Effect of the Invention

[0015] According to the present invention, a fluid spraying unit excellent in operational safety and efficiency can be provided. [Brief description of the drawings]

[Diagram 3] FIG. 2 is a schematic diagram of a piping body in the embodiment. [Figure 4] Schematic diagram of a dispersion joint in this embodiment. [Diagram 5] 5 is a schematic diagram of a movable mechanism according to the embodiment. FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] The fluid spray unit 1 of the present invention is used to spray fluid from a high place, and specific embodiments thereof will be described in detail below with reference to the drawings. In this description, common parts are given common reference symbols throughout the drawings unless otherwise specified. In addition, the elements of each embodiment are not necessarily shown to scale in the drawings. In addition, some symbols may be omitted to make each drawing easier to see.

[0018] The fluid spraying unit 1 of this embodiment is attached to a high place to spray a fluid. Examples of high places to which it can be attached include the rooftop of a building or condominium, a net fence on a ground, and a scaffold at a construction site or a building site.

[0019] As shown in Figures 1 and 2, the fluid spraying unit 1 of this embodiment comprises a first pipe 2 having a first flow path 2a formed therein and extending in the vertical direction, a second pipe 3 having a second flow path 3a formed therein and extending in the horizontal direction, and having at least one fluid outlet 8 for spraying fluid, and a connecting fitting 4 provided on the first pipe 2 to detachably connect the second pipe 3, and having a third flow path 4a formed therein that communicates the first flow path 2a and the second flow path 3a.

[0020] As shown in Fig. 1, the first pipe 2 extends vertically to the portion where the second pipe 3 is arranged, and may be, for example, an iron pipe or a pressure-resistant hose. Inside the first pipe 2, as shown in Fig. 2, a first flow path 2a extending vertically is formed, and fluid is supplied to the first flow path 2a from a fluid supply device (e.g., a sprinkler pump, etc.) (not shown) connected to the starting end close to the ground. The terminal end of the first pipe 2 is connected to a connecting joint 4.

[0021] When the first pipe 2 is used at a demolition site or the like, the first pipe 2 is attached to a scaffolding (not shown) installed on the building. The scaffolding is composed of a plurality of frameworks (not shown) in a substantially rectangular parallelepiped shape, in which a plurality of frames are assembled vertically, horizontally, and diagonally as appropriate to cover the periphery of the building to be demolished, and fixed with clamps or the like, and the framework is assembled to a position higher than the height of the building. This framework is configured by appropriately combining in the vertical, horizontal, and lateral directions according to the shape of the building to be demolished. Therefore, when the first pipe 2 is attached to the scaffolding, specifically, it is attached to the framework that constitutes the scaffolding, but the length of the extension direction of the first pipe 2 is set so as to be longer than the height of the building, and the framework is appropriately changed according to the demolition situation of the building, so the framework to which the first pipe 2 is attached is also changed according to the demolition situation of the building.

[0022] A plurality of first pipes 2 may be provided depending on the application of spraying, and in particular, a pair of first pipes 2 may be provided at a predetermined interval corresponding to the horizontal length of second pipe 3 as shown in FIG.

[0023] As shown in Figures 1, 2, 3 and 4, the second pipe 3 has a second flow path 3a formed therein and extends horizontally, and is provided with at least one fluid outlet 8 for ejecting a fluid. The second pipe 3 includes a pipe body 5 having a second flow path 3a formed therein and extending horizontally, and a spray joint 6 having a fluid outlet 8, connected to the pipe body 5, and having a spray flow path 10a formed therein for causing the fluid to flow from the second flow path 3a to the fluid outlet 8.

[0024] The second pipe 3 is configured by alternately connecting the pipe main body 5 and the spray joint 6, and in FIG. 1, the second pipe 3 is configured by alternately connecting three pipe main bodies 5 and two spray joints 6. The number of pipe main bodies 5 and spray joints 6 is appropriately changed depending on the application and spraying location. In addition, one end of the pipe main body 5 constituting both ends of the second pipe 3 is connected to the first pipe 2 via a connecting joint 4, respectively.

[0025] As shown in Figures 2 and 3, the piping body 5 has the second flow path 3a formed therein and extends horizontally, and can be, for example, an iron pipe, a vinyl pipe, a fiber-reinforced plastic pipe, etc. Nuts 26 corresponding to bolts 27 of the spray joint 6 described later are arranged on both ends of the piping body 5, and a plug is provided inside the opening, which becomes a male coupler 7a.

[0026] As shown in FIG. 4, the dispersion joint 6 is composed of a T-shaped tee pipe, and includes a straight path 9 and a branch path 10 disposed at a right angle to the straight path 9.

[0027] 2 and 4, the straight passage 9 is provided with a fluid supply passage 9a whose both ends communicate with the second passage 3a of the piping body 5. The outer peripheral surface of both ends of the straight passage 9 is threaded to form a bolt 27, and the inner peripheral surface of the bolt 27 is provided with a socket that detachably engages with the plug described above, which serves as a female coupler 7b.

[0028] 2 and 4, a nozzle serving as the fluid outlet 8 is fitted into the branch passage 10 at its tip, and the branch passage 10 is connected to the fluid supply flow passage 9a and is provided with a spray flow passage 10a that causes the fluid to flow from the fluid supply flow passage 9a to the fluid outlet 8. The nozzle serving as the fluid outlet 8 sprays the fluid in a mist or direct jet form, and can be used in either a mist or direct jet form.

[0029] The plug (male coupler 7a) provided on the piping body 5 is inserted into the socket (female coupler 7b) provided on the straight path 9 of the spray joint 6, and the bolt 27 provided on the spray joint 6 is tightened with the nut 26 of the piping body 5, thereby fastening the piping body 5 and the spray joint 6. The worker can easily assemble the second piping 3 having the desired horizontal length by simply inserting the piping body 5 into the spray joint 6 and turning the nut 26.

[0030] The second pipe 3 is provided with an adjustment mechanism 11 that is provided on the spray joint 6 and adjusts the spray direction of the fluid outlet 8. As shown in FIG. 5, the adjustment mechanism 11 includes a fixture 12 for fixing the spray joint 6 in a predetermined position, and a holder 13 that is connected to the fixture 12 and holds the spray joint 6.

[0031] The fixture 12 is provided so as to be detachable from the object to be fixed, and for example, at a demolition work site, it is fixed by being sandwiched between a frame constituting a framework arranged adjacent to the spray joint 6. Although the fixing configuration is not particularly limited, in this embodiment, the fixture 12 includes a metal band having a substantially circular ring shape and a screw for changing the circumferential length of the band. With this configuration, the band is arranged around the frame, and the circumferential length of the band is adjusted with the screw to be approximately the same as or slightly smaller than the circumferential length of the frame, thereby pressing the band to the frame and fixing the fixing part 12 to the frame.

[0032] The holder 13 is connected and fixed to the fixing device 12, and is equipped with a screw-threaded portion 14 that screws into a thread (not shown) provided in the straight passage 9 of the spray joint 6, and an angle adjustment mechanism 15 that adjusts the spray angle of the fluid nozzle 8.

[0033] The angle adjustment mechanism 15 includes a holding plate 16 having both ends bent into a U-shape on one side thereof for holding the screw portion 14 screwed into the spray joint 6, and a connecting plate 17 having both ends bent into a U-shape on one side thereof for connecting to the fixed portion 12. One side of the holding plate 16 and one side of the connecting plate 17 are arranged to face each other, and both bent side surfaces of the holding plate 16 and both bent side surfaces of the connecting plate 17 are arranged close to each other.

[0034] Both folded side surfaces of the retaining plate 16 and the connecting plate 17 are penetrated and connected by a rod member 25. In addition, an elastic member 18 (a coil spring in this embodiment) is connected to one surface of the retaining plate 16 and the connecting plate 17, and a lever 19 that compresses or pulls the elastic member 18 is provided on one surface of the retaining plate 16.

[0035] With this configuration, when an operator operates lever 19 to pull elastic member 18, rod member 25 becomes the rotation axis, and holding plate 16 rotates in the circumferential direction of second piping 3 relative to connecting plate 17. This makes it possible to adjust the jetting angle of fluid jet outlet 8 and spray fluid at a desired position.

[0036] The connecting joint 4 connects the first pipe 2 and the second pipe 3, and detachably connects the first pipe 2 and the second pipe 3. As shown in FIG. 2, the connecting joint 4 has a third flow path 4a therein that connects the first flow path 2a and the second flow path 3a.

[0037] When the connecting joint 4 connects one end of the second pipe 3 to the first pipe 2, the fluid is supplied to the second pipe 3 from only one direction, but when the connecting joint 4 connects both ends of the second pipe 3 to the first pipe 2, as shown in Fig. 1, the fluid is supplied to the second pipe 3 from two directions. The state of the first pipe 2 and the second pipe 3 connected by the connecting joint 4 is appropriately changed according to the horizontal distance of the second pipe 3, and in particular when the fluid is supplied from two directions at both ends of the second pipe 3, it is possible to prevent the pressure of the fluid from dropping midway.

[0038] The third flow path 4a is provided with a valve for opening and closing the third flow path 4a, and in this embodiment, an electromagnetic valve 20 is used. The electromagnetic valve 20 includes a solenoid unit (not shown) that receives an opening / closing signal from the outside to move a plunger, and a valve unit that is connected to the plunger to open and close the third flow path 4a. Note that the valve is not limited to the electromagnetic valve, and a manual valve may be used, and the type of valve may be changed appropriately to a globe valve, a gate valve, a ball valve, or the like.

[0039] The electromagnetic valve 20 is controlled by a controller terminal 21, and the controller terminal 21 is connected to the electromagnetic valve 20 via a network as shown in Fig. 2. In addition, as a mode for connecting the electromagnetic valve 20 and the controller terminal 21, for example, a wireless LAN such as wifi may be provided in the fluid spraying system 1, but as another example, they may be connected by wire, or a communication standard such as Bluetooth (registered trademark) or satellite communication may be used.

[0040] The controller terminal 21 includes a CPU, memory, a communication port, a network interface, etc. (not shown), and may be, for example, a remote control, a smartphone, a tablet terminal, a PC, etc.

[0041] As shown in FIG. 2, the controller terminal 21 includes a transmitting unit 22 that transmits an opening / closing signal to open / close the solenoid valve 20, a control unit 23 that creates the opening / closing signal based on an external operation or a predetermined threshold, and a judgment unit 24 that receives detection information transmitted from an external device, judges whether the detection information has exceeded / fallen below the predetermined threshold, and transmits a judgment signal.

[0042] The determination unit 24 transmits a determination signal based on the detection information transmitted from the detector and a predetermined threshold input in advance. As an example of this determination unit 24, for example, it receives temperature information (detection information) transmitted from a temperature sensor (detector) (not shown) disposed near the electromagnetic valve, and transmits a determination signal to the control unit 23 when the temperature information exceeds a predetermined threshold input in advance (for example, when it exceeds 35°C). Also, it transmits a determination signal to the control unit 23 when the temperature information transmitted from the temperature sensor falls below a predetermined threshold input in advance (for example, when it falls below 25°C).

[0043] As another example, humidity information transmitted from a humidity sensor (detector) may be used. Furthermore, the controller terminal 21 may be configured to receive time information (detection information) from a clock (detector) built into the controller terminal 21, and transmit a determination signal to the control unit 23 when the time information exceeds a predetermined threshold value input in advance (for example, when eight hours have passed since the transmitting unit 22 transmitted a close signal to close the electromagnetic valve 20). Note that the configuration of the determining unit 24 is not limited to the above example, and the design may be changed as appropriate depending on the intended use and the usage situation.

[0044] The control unit 23 receives a determination signal from the determination unit 24, creates an opening / closing signal for opening / closing the third flow path 4a, and transmits the opening / closing signal to the transmission unit 22. The control unit 23 also receives an operation signal input by an external operation of the controller terminal 21, creates an opening / closing signal for opening / closing the third flow path 4a, and transmits the opening / closing signal to the transmission unit 22.

[0045] The transmitter 22 transmits an opening / closing signal to the electromagnetic valve 20, and the solenoid portion of the electromagnetic valve 20 opens and closes the third flow path 4a by moving the plunger and a valve portion connected to the plunger.

[0046] The fluid sprinkling unit 1 in this embodiment configured as described above provides the following special effects.

[0047] In the fluid spraying unit 1 of this embodiment, one end of the first pipe 2, which is arranged extending vertically, is arranged at a low position and the other end is installed at a high position, and if the other end of the first pipe 2 is connected to the second pipe 3 via the connecting joint 4, the fluid can be supplied from one end of the first pipe 2 at a low position to the second pipe 3 via the connecting joint 4. Therefore, the worker can safely spray the fluid from a low position. In addition, since the fluid spraying unit 1 of the present invention is composed of only three parts, the first pipe 2, the second pipe 3, and the connecting joint 4, anyone can easily install it. Therefore, it can be used for various purposes in various sites such as heat stroke countermeasures, rooftop greening and cooling, dust countermeasures, and concrete curing.

[0048] In particular, when the fluid spraying unit 1 of this embodiment is used at a demolition site, where many heavy machines come and go, if a hose is laid across the demolition site, the heavy machines may accidentally run over and damage the hose. However, the fluid spraying unit 1 of this embodiment supplies fluid to the second pipe 3 using the first pipe 2 that extends from a low place to a high place, so it is possible to prevent the heavy machines from accidentally damaging the hose.

[0049] In addition, since the second pipe 3 is configured by connecting the pipe main body 5 and the spray joint 6, the horizontal length of the second pipe 3 can be adjusted, and optimal fluid spraying can be performed according to the work location. In addition, the pipe main body 5 and the spray joint 6 are fastened to each other by inserting a plug (male coupler 7a) provided on the pipe main body 5 into a socket (female coupler 7b) provided on the straight path 9 of the spray joint 6 and tightening a bolt 27 provided on the spray joint 6 with a nut 26 of the pipe main body 5. Therefore, the worker can easily connect the pipe main body 5 and the spray joint 6, and the safety of the worker can be improved even when the second pipe 3 is assembled at a high place.

[0050] Furthermore, the second pipe 3 is provided with an adjustment mechanism 11 that is provided in the spray joint 6 and adjusts the spray direction of the fluid spray nozzle 8, and the adjustment mechanism 11 is provided with an angle adjustment mechanism 15 that adjusts the spray angle of the fluid spray nozzle 8. Therefore, the angle adjustment mechanism 15 can adjust the spray angle of the fluid, allowing the fluid to be sprayed at an appropriate position depending on the application.

[0051] Furthermore, the connecting joint 4 is provided with an electromagnetic valve 20 that opens and closes the third flow path 4a, and a controller terminal 21 that controls the electromagnetic valve 20 is also provided, so that the operator can remotely operate the device and spray fluid at high altitudes without any personnel present, further improving operator safety. In addition, if the control unit 23 of the controller terminal 21 creates an opening / closing signal when a predetermined threshold is exceeded / fell below, automatic spraying can be performed, which can also help to alleviate the labor shortage that has become an issue in various industries in recent years.

[0052] The present invention is not limited to the above-described embodiments.

[0053] The first pipe is not necessarily connected to both ends of the second pipe, but may be provided only at one end of the second pipe, and a connecting joint may also be provided only at this one end. An example of a case in which the first pipe is provided only at one end of the second pipe is a case in which the horizontal distance of the second pipe is short and fluid is supplied from only one direction.

[0054] In addition, the number of the piping bodies and the spray joints constituting the second piping is not limited to the above configuration, and may be, for example, a pair of piping bodies and a spray joint. In this case, it is sufficient to configure one end of the straight path of the spray joint to be closed.

[0055] The configuration for connecting the piping body and the spray joint that constitute the second piping is not limited to the above, and can be changed as appropriate depending on the usage mode.

[0056] Furthermore, the nozzles are not limited to those in the above-mentioned embodiment, and the shape and diameter of the spray nozzle can be appropriately selected, for example, a nozzle that only performs direct spraying, a nozzle that only performs mist dispersion, a shower-like nozzle, etc. Also, each nozzle may be configured to spray intermittently, or the nozzle itself may be configured to swing or rotate.

[0057] Furthermore, when the control unit receives an operation signal input by external operation of the controller terminal and creates an opening / closing signal for opening and closing the third flow path, the controller terminal may include only the transmission unit and the control unit.

[0058] The connecting joint may not only connect one first pipe to one second pipe, but may also connect, for example, multiple first pipes to multiple second pipes, a first pipe to multiple second pipes, or multiple first pipes to multiple second pipes.

[0059] The present invention can be modified in various ways without departing from the spirit of the invention. [Explanation of symbols]
