Description

  The present invention relates to a snow removal device for preventing snow accumulation on a roof or the like.

  It is not uncommon for the Hokuriku and Tohoku regions, including mountainous areas such as the Hida region in Gifu Prefecture, to have a snow cover of over 1m in winter, and residents and local governments are taking various snow measures. Nowadays, with the spread of snow removal equipment and the high performance of snow removal machines, the minimum functions of public goods such as trunk roads that are essential for daily life can be maintained even in the severe winter season. However, it is necessary to remove snow on its own for private homes, and it is particularly dangerous to remove snow from the roof because it is a work at a high place with poor footing. It is difficult and still has many challenges.

  Measures to reduce snow falling on the roof are also underway, and in addition to the method of giving the building enough strength to withstand snow accumulation, the method of heating by laying heating wires on the roof, sprinklers etc. are used to spray water The way to do it has become practical. However, when increasing the strength of a building, there is a problem that it is difficult to deal with other than at the time of new construction, and construction costs also increase. In addition, when heating wires are laid, it is difficult to deal with other than at the time of new construction, and there is also a problem that power consumption increases. The watering method is easy to install in existing houses and can be installed on its own, but it is ineffective in areas where the water current does not reach, and it is difficult to manage the direction and distance of the water flow.

  Some general-purpose sprinklers have a swing function called an impact type. Some water sprinkles while rotating using water pressure. Such sprinklers have a wide range of water flow and are also used for snow removal, but it is necessary to adjust the water pressure and water volume to make them function properly, and foreign substances in the water can cause malfunctions. Therefore, water quality management is also necessary. Therefore, various devices are required to supply water, and it cannot be easily installed. Moreover, if the water pressure is increased in order to increase the snow extinguishing ability, the water flow may be scattered on a road away from the roof, which may cause unspecified people such as passersby to feel uncomfortable.

  The present invention was developed based on such a situation, and aims to provide a snow extinguishing apparatus that can efficiently remove snow such as a roof.

  A device according to claim 1 for solving the above-mentioned problem is provided with a main water passage for allowing water to pass through and a main shaft extending rotatably and extending in the vertical direction, and extending in the horizontal direction from the main shaft. And an arm provided with a sub-water channel communicating with the main water channel, a power source for forcibly rotating the main shaft, and a joint for supplying water to the main water channel, Is equipped with a nozzle for injecting water from the sub-water channel to the outside, and the arm is rotated by a power source and water sent to the sub-water channel through the joint and the main water channel is injected from the nozzle. A snow erasing apparatus that removes snow.

  The main shaft is a bar having a circular cross section extending in the vertical direction, and is held by a bearing or the like, so that it can freely rotate but is restricted from moving in the axial direction. The main water channel has a role of circulating water and is formed by making the inside of the main shaft hollow. The vertical direction means the vertical direction, but a slight inclination is allowed as a matter of course. Next, one end of the arm is fixed to the upper portion of the main shaft, and extends in a lateral direction perpendicular to the main shaft. Further, the secondary water channel is formed by hollowing the inside of the arm and communicates with the main water channel formed on the main shaft, so that the water flowing through the main water channel smoothly flows into the secondary water channel. There is no limit to the number of arms that can be attached to one spindle, but it is excellent in terms of balance and the like when two arms are arranged in a letter shape. The length of the arm is not limited and can be freely determined.

  The power source is used to forcibly rotate the main shaft and can be selected in various ways including an electric motor and a device using hydraulic pressure. Note that the power source according to the present invention does not use the pressure of water to be sprayed unlike a conventional sprinkler. When the main shaft is rotated by this power source, the radially extending arms also rotate together. Regarding rotation, in addition to a simple method of maintaining a constant angular velocity, measures such as limiting the rotation range to a fixed angle and changing the number of rotations according to the situation are possible. There is no restriction on the drive system connecting the power source and the main shaft, and general-purpose products such as belts and chains can be freely selected.

  The nozzle has a role of injecting water flowing through the secondary water channel in the arm to the outside, and is composed of a base with a throttle. In principle, the nozzle is provided near the tip of the arm, but a nozzle may be provided near the middle of the arm to spray water from a plurality of locations.

  The joint has a role of supplying water to the main shaft from a pipe fixed to the ground or a building, and is attached to the lower end surface of the main shaft. This joint has an O-ring incorporated therein so that water can be supplied to the rotating main shaft without leakage. The water injected from here is sent to the sub-water channel in the arm via the main water channel of the main shaft, and is finally ejected from the nozzle to the outside. The water supplied to the joint is difficult to use public water from the viewpoint of pressure and water volume, and it is preferable to pump the water from the river or pond with a pump. River water has a low snow temperature due to its low temperature, but can increase its capacity by increasing the flow rate.

Thus, by ejecting water from an arm that rotates with an electric motor or the like, it becomes possible to send a large amount of water over a wide range, and snow that accumulates on a wide surface such as a roof can be efficiently removed. And since water is injected from the front-end | tip of an arm, compared with the conventional sprinkler, the flow rate can be suppressed and water does not scatter more than necessary.

  The invention according to claim 2 further enhances snow removal efficiency, and the nozzle is capable of adjusting the direction of water to be sprayed. By making the nozzle a movable structure as in the present invention so that the attitude of the injection port can be changed, it is upward when you want to widen the water splash range, and downward when you want to narrow down the water. Flexible response is possible.

  As in the present invention, by jetting water from a rotating arm using a unique power source such as an electric motor, it becomes possible to supply water over a wide range according to the length of the arm, and about the roof of a house If it is a large area, it is possible to prevent the entire snow cover by installing only a few devices. Moreover, since the flow rate of the water to be injected can be suppressed, the water scatters to a place away from the roof, so that a passerby does not feel uncomfortable. Furthermore, since the structure of the present invention is simple, there are few restrictions such as water quality, and the cost required for maintenance is low. In order to carry out the present invention, a sufficient amount of water is necessary, and it is best to use water from rivers and ponds. However, in mountainous areas, there are many rivers around houses, and in terms of water supply. There is little problem.

  FIG. 1 is a perspective view showing the structure of a snow-melting device 1 according to the present invention. Various parts are incorporated in the inside of the main body 11 formed in a cylindrical shape, and a plurality of legs 12 for mounting on a roof or the like are attached to the side peripheral surface. The main body 11 is a sealed container in which water and snow do not enter, but in the drawing, a part of the main body 11 is drawn to show the internal structure. The main shaft 13 is a rod having a circular cross section, and penetrates the center of the main body 11 up and down. The inside of the main shaft 13 is hollow and serves as a main water channel 14 for sending water. Further, the main shaft 13 is held so as to be smoothly rotated by a cylindrical upper bearing 25 and a lower bearing 26 with a ring-shaped flange, and in order to protect the inside of the main body 11, both bearings 25 and 26 are watertight. Sex is also secured. Further, in order to receive the vertical load acting on the main shaft 13, an annular flange 15 is formed in the middle, and a ball bearing 27 (thrust bearing) incorporating a steel ball is interposed between the flange 15 and the lower bearing 26. ). In addition, a joint 19 for sending water to the main water channel 14 is attached to the lower end surface of the main shaft 13. The water injection port 20 extending from the side surface of the joint 19 has a role of taking in water from a pipe 32 such as a hose and maintains a stationary state even when the main shaft 13 is rotating.

  The arm 21 is a rod-shaped member extending radially with respect to the rotation direction of the main shaft 13, and one end surface of the arm 21 is inserted into a letter-shaped joint 17 formed on the upper portion of the main shaft 13 so as not to be detached by an external force. It is integrated by bonding. The inside of the arm 21 is hollow, is a sub-water channel 22 communicating with the main water channel 14 of the main shaft 13, and a nozzle 23 for injecting water to the outside is attached near the tip of the arm 21. Since the nozzle 23 can rotate about the arm 21, the injection direction can be freely adjusted, and it is also possible to turn one side horizontally and the other downward as shown. In addition, since the arm 21 is cantilevered and the vicinity of the tip is easily deformed, a mast 18 is installed on the main shaft 13 and a rope 24 is stretched from here to the tip of the arm 21 to increase the strength.

  An electric motor 28 that is a power source for rotating the main shaft 13 is fixed inside the main body 11, and only the wiring 30 for supplying electric power extends to the outside. A pulley 16 is incorporated in the main shaft 13, and the electric motor 28 and the pulley 16 are connected by a belt 29. As the belt 29, a belt having a groove that does not generate slip and does not need to be adjusted in tension is used. When a general-purpose induction motor or the like is used for the electric motor 28, the rotation speed becomes excessive, so that a speed reducer is incorporated.

  The water used in the present invention is pumped by a pump 31 from a water source 33 such as a river or a pond, and is supplied to the inlet 20 via a pipe 32. From the test results so far, when the length of one arm 21 is 1 m and two arms 21 are used as shown in the figure, 100 liters of water is supplied per minute while the main shaft 13 is rotated 10 times per minute. Then, it has been found that snow can be removed without problems even in heavy snow.

  FIG. 2 shows a central longitudinal section of the snow-melting device 1 shown in FIG. The main shaft 13 is a hollow rod having a circular cross section, and a flange 15 for transmitting a vertical load and a pulley 16 for hanging a belt 29 are incorporated, and an upper part is a letter-shaped joint for attaching an arm 21. 17 is formed. The upper bearing 25 and the lower bearing 26 that support the main shaft 13 rotatably use simple sliding bearings, but various bearings can be used as long as the watertightness can be maintained. Since the vertical load acting on the main shaft 13 is supported by the ball bearing 27, the rotation is not affected even when an excessive load is applied.

  FIG. 3 shows an example of usage of the present invention. In the building 34 having a simple structure depicted in the drawing, the roof is covered with a tile 35, and a strip-shaped ridge 36 is formed on the top of the roof. Two snow extinguishing apparatuses 1 are placed on both sides of the roof, and the legs 12 are arranged across the ridge 36. A pond adjacent to the building 34 serves as a water source 33, and a pump 31 is installed beside the water source 33, and a pipe 32 extends from here toward the snow removal device 1 on the roof. In addition, the wiring 30 that supplies power for rotating the arm 21 is connected to an outlet 37 on the side of the building 34. Although illustration is omitted, the automatic operation of the snow removal device 1 can be performed by combining the sensor for detecting snowfall and temperature after the rotation of the arm 21 and the operation of the pump 31 can be automatically operated remotely. Is possible.

It is a perspective view which shows the structure of the snow-melting apparatus by this invention. It is a center longitudinal cross-sectional view of the snow removal apparatus shown in FIG. The example of the usage pattern of this invention is shown.
