Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention mainly relates to a snow-melting nozzle device used for melting snow on a road surface in a snowy country and thus preventing snow from being accumulated on the road surface.

[0002]

[Prior art]

 Previously, the same applicant as in the present application provided a snow-melting nozzle device of a type in which a T-shaped cheese is used to change the elevation angle and depression angle of a short tubular nozzle in Japanese Patent Application No. 4-51770.

[0003]

[Problems to be solved by the device]

 The snow-melting nozzle device described in the above-mentioned prior art must be constructed to prevent water leakage from the connecting screw portion between the T-type cheese and the water supply whenever the elevation angle and depression angle of the tubular nozzle are changed. In addition, it was limited to the usage that only a relatively small elevation angle / depression angle could be changed, and there was a defect that it took time to change the elevation angle / depression angle.

An object of the present invention is to provide a new snow-melting nozzle device that solves the above-mentioned defects.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the snow-melting nozzle device according to the present invention has a discharge port 3 which is opened sideways in a valve 4 having a connection port 1 to a water supply pipe and a discharge port 3 which is opened and closed by a valve body 2. A large diameter shaft hole 5 is continuously provided at the outer end of the discharge port 3, and a short cylindrical rotary shaft 6 is connected to the shaft hole 5 in a state where the inner diameter hole 7 of the rotary shaft 6 and the discharge port 3 are in communication with each other. The disk-shaped enlarging head 9 is attached to the outer end of the rotary shaft 6 so that it can be rotated around the wire 8, the pin 12 and the groove 13 are not removed, and the O-ring 14 is watertight. A jet port 10 is integrally provided to the peripheral surface of the bulging head 9 so that the jet port 10 faces the lateral line 8 and the inner end communicates with the inner diameter hole 7. A rotation stopping screw 11 is provided on the peripheral wall of the.

[0006]

[Action]

 The present invention is constructed as described above. For example, as shown in FIG. 4, water pipes 18 are erected at places of a water pipe 17 buried in a central separation point 16 of a road 15, and the upper ends of these water pipes 18 are provided. It is attached (screwed) to and used. In the case of this use, the front surface of the bulging head 9 (the reflecting surface which will be described later in the embodiment) is oriented in the direction opposite to the traveling direction of the vehicle (the facing direction).

In order to change the direction of the fountain in the above-mentioned use, first loosen the rotation stopping screw 11, twist the enlarging head 9 in this loosened state to orient the ejection port 10 in a desired direction, and then rotate it. It is only necessary to tighten the set screw 11. In the embodiment shown in the drawings, the tip of the rotation stopping screw 11 is used as the pin 12 that engages with the groove 13, so that the screw 11 should not be loosened too much.

[0008]

【Example】

 In the embodiment shown in the drawing, a horizontal connection outlet 1 is opened and closed by a threaded connection port 1 to a water supply pipe 18 on the lower surface and a valve body 2 which is opened and closed by twisting with a driver (not shown). A large diameter shaft hole 5 is connected to the outer end of the discharge port 3 in the valve 4, and a short cylindrical rotary shaft 6 is inserted into the shaft hole 5 and the inner diameter of the rotary shaft 6 is increased. The hole 7 and the discharge port 3 communicate with each other, the state of being rotatable around the lateral line 8, the state of not being removed by the engagement of the pin 12 and the groove 13, and the state of being watertight by the O-ring 14 are fitted, and the rotary shaft is attached. A disk-shaped enlarging head 9 is integrally provided at the outer end of 6, and a jet port 10 is provided on the peripheral surface of the enlarging head 9 in a direction orthogonal to the lateral line 8 and an inner end communicates with the inner diameter hole 7. And a screw 11 for stopping rotation is provided on the peripheral wall of the shaft hole 5. Serial by sticking the retroreflective sheet 19 on the outer surface of the large head 9 is obtained by a reflection surface. In the figure, 20 indicates an O-ring.

FIGS. 6 and 7 show a second embodiment, which has two front and rear bulged heads 9 each having a jet port 10 which can be turned individually.

[0010]

[Effect of device]

 The snow-melting nozzle device according to the present invention has a valve 4 having a connection port 1 to a water supply pipe and a discharge port 3 which is opened and closed by a valve body 2 in which a discharge port 3 is laterally opened and the lateral side discharge port 3 has an outer end. A large diameter shaft hole 5 is continuously provided, and a short cylindrical rotary shaft 6 can be rotated around the lateral line 8 in a state where the inner diameter hole 7 of the rotary shaft 6 and the discharge port 3 are in communication with each other. State, the state in which the pin 12 and the groove 13 are not removed and the state in which the pin 12 and the groove 13 are not removed, and the O-ring 14 is a watertight state. A jet port 10 is formed on the peripheral surface of the large head portion 9 in a direction orthogonal to the lateral line 8 and an inner end of the large head portion 9 communicates with the inner diameter hole 7, and rotation prevention is performed on a peripheral wall of the shaft hole 5. Since the screw 11 is provided, the range in which elevation angle and depression angle can be changed can be made larger than that of the conventional one. There, it is possible to facilitate the change, be capable of not need the work prevents leakage that was Do every time the change can be fully achieved the desired object.
