Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a snow melting apparatus having a novel configuration.

As a combined snow-melting system with a water-sprinking snow-melting device and a non-water-sprinkling device for the purpose of melting snowfall in winter in severe cold regions, a closed-type solenoid valve (solenoid valve) that energizes weather information detected by a snowfall sensor Only) and a part of the snowmelt medium flowing to the non-sprinkling snow-melting device is turned into snow-melting water by the snow-melting water surface touch jet spill device, and touch-spills to the snow-covered road surface. Serves as an item.

1. During heavy snowfall, snow can be eliminated in the same time as the watering type.

2. Since the road surface touch jet spills out, there is no scattering of snow-melting water due to the effects of wind, etc., and there is no damage from freezing on other objects.

3.Melted water that has been snow-melted by the snow-melting water is kept at a temperature equal to or higher than the snow-melting temperature by the non-sprinkling snow-melting device that is operating at the same time. Runs down the drain without any adverse effects.

Due to the above-mentioned snow-melting operation, the snow-melting road surface is secured even when the snow is extremely heavy or when the temperature is frozen and severely cold.

Of course, when the snowfall is not so intense, the electromagnetic valve operates based on the detection information of the snowfall sensor, and only the non-sprinkling snow melting apparatus operates to fulfill the following items.

1. Since the snow melting pipe is installed on the pavement and pavement as a non-sprinkling snow melting device, the pavement maintains the snow melting temperature by the heat energy radiation of natural water (groundwater) as a snow melting medium liquid.

2. For the above reasons, the snowfall is not very intense, and the snow is melted.

3. The groundwater of the snowmelt medium in the snowmelt pipe is radiated, and then returned to the underground by the return well to maintain the groundwater.

4. The snow melt on the road surface flows down into the drain.

By the above-mentioned snow melting operation, a snow melting road surface at the time of snowfall is ensured, and when there is no snowfall, the snow melting water can be stopped in the snow melting pipe by the closed solenoid valve at the time of energization based on the information of the snowfall sensor, which is economical.

That is, by combining a non-sprinkling snow-melting device and a water-sprinking snow-melting device with a snowfall sensor and a solenoid valve, an attempt is made to provide a snow-melting device that can be called a combined snow-melting device that is also effective as an interlocking operation device. is there.

[Prior Art] Conventionally provided snow melting methods include two methods, a sprinkling method using groundwater and a non-sprinkling method.

Of these, it is said that a non-sprinkling type with few freezing obstacles is preferable in severe cold regions.

The sprinkling method is a method in which groundwater is sprinkled directly on snow to eliminate snow.

The non-sprinkling type includes a method in which groundwater is used as a snow-melting medium liquid and a method in which snow is melted using an antifreeze liquid that can prevent freezing even when circulation is stopped.

At present, all of these devices are operated and operated only by a single snow melting device, but there are advantages and disadvantages, and further development of an efficient snow melting device is awaited.

[Problem to be Solved by the Invention] The conventional technology has the following problems.

A. In the case of the water spraying method, the water spraying method has been used in the heavy snowfall area where the cold weather is not so severe as in the case of Honshu, which has been used most often in the past.
In cold regions (Hokkaido), improvements in the following items are required.

1. Adhesion and freezing on objects on the road surface.

Since it is a water spray type, snow is sprayed at an appropriate fountain height on the road surface, but it is scattered on wind or passing objects on the road surface and freezing damage occurs due to severe cold temperatures.

2. Snow melting water melted by snow melting may re-freeze and cause road surface management problems.

In severe cold regions, at the same time that snow melts into water and, on the other hand, there is severe climatic reality in which it freezes, so it is difficult to manage the snowmelt water generated by snowmelt.

3. Snow melting water that has lost watering power due to power outages freezes.

If the snow water in the water sprinkler loses water sprinkling power due to power outage etc.,
Cooling and freezing of the snow-melting water, which had been in operation, began to freeze completely.

B. In the case of the non-sprinkling method, in severely cold regions, a snow-melting method using a non-sprinkling snow-melting medium liquid was developed based on various obstacles to the spraying method.
The history is short, the performance results have a sense of urgency, and it has not been fully used.

 The reason is as follows.

1. Freezing of snowmelt water that has lost circulation due to power outages.

When the circulating power of the snow-melting medium in the snow-melting apparatus is lost due to a power failure or the like, the cooling and freezing of the snow-melting water starts in severely cold regions, and finally freezes completely.

2. Various snow melting methods using antifreeze as a medium for melting snow have been developed for the above reasons, but they have not been completely used for the following reasons.

I. Antifreeze liquid weight loss phenomenon It is difficult to completely pipe the antifreeze liquid as a snow-melting medium liquid in the waterless snow melting equipment without water leakage, and there is some leakage. Therefore, additional work of antifreeze liquid and work to detect the weight loss are necessary.

B. Environmental protection Leakage of antifreeze is not desirable for environmental protection.

C. Expensive burden is large.

A complete device for maintaining the antifreeze liquid of the snow-melting medium is labor-intensive, time-consuming and expensive.

However, it is also true that the non-sprinkling snow-melting equipment is suitable for severe cold regions, but the heat energy of natural water (groundwater) was directly used for snow removal within a short period of time for mass snowfall due to massive snowfall. It is more efficient.

That is, the development of a snow melting apparatus that combines the advantages of the water spraying type and the advantages of the non-sprinkling type, and can be referred to as a combined snow melting apparatus having good mutual effects, has been awaited.

[Means for Solving the Problems] In the present application, the above-described problem is to be solved by the following configuration.

Focus to solve the problem 1. In severe cold, whether the snow-melting medium water in the non-sprinkling snow-melting pipe loses its circulating power due to power outage etc. does not freeze.

2. If snowfall is severe due to heavy snowfall, whether the snow removal efficiency is good.

3.If snowfall and snowfall are not particularly intense, snowmelt operation is possible,
Is it possible to maintain the road surface without re-freezing the resulting snowmelt?

4. Whether the weather conditions of snowfall and snowfall can be detected.

5. What happens when an antifreeze is used as the snow-melting medium?

6. What if natural water (groundwater) is used as the snowmelt medium?

7. Whether the water spray method with good snow-melting efficiency causes damage such as freezing due to wind and other scattered adhesion to other objects on the road surface.

Configuration of problem solving 1. Snow-melting medium water in the pipes starts draining simultaneously with the power failure due to the operation of the energized closed solenoid valve installed at the lowest part of the non-sprinkling snow-melting pipe, and it becomes anhydrous and does not freeze.

2. Spraying natural water (groundwater) directly on snow is an efficient method of thermal energy.

3. Snow melting and road surface preservation can be achieved by maintaining the road surface temperature at the snow melting temperature by the waterless method.

4. Install a snowfall sensor.

5. It is difficult to work the piping without leaking the antifreeze liquid completely.

6. Returned to the return well to prevent the depletion of groundwater and protect the environment.

7. If the water spray is made to flow out of the road surface, there is no influence of wind, etc., and no damage will be caused by scattering adhesion to other objects.

As a result of examination as the focus of problem solving divided into the above 1 to 7 items, it was found that the conventional watering type has good snow removal efficiency,
In severe cold regions, a non-sprinkling snow melting method is preferred.

In other words, the snow melting effect is inferior to the snow removal efficiency, but it is superior to the measure relating to complete freezing, which should never be present.

In addition, it is better not to use antifreeze as the snow-melting medium liquid for the following reasons.

1. Leakage of antifreeze may cause pollution.

2. Requires a heat exchanger, etc., which increases costs.

3. Increase in maintenance work.

For the above reasons, a newly-developed system newly sorted and guided is developed.

In severely cold regions (Hokkaido), even if the water circulation method is lost due to heavy snowfall even if the non-sprinkling method, which has excellent anti-freezing measures, loses circulation power due to snow melting medium water, the energized closed solenoid valve installed at the bottom of the snow melting pipe before freezing. Preventing freezing of snowmelt water drained by opening the pipes is an essential condition for restarting the snowmelting equipment.

In other words, in a severe cold area, a non-sprinkling type is preferable in a snow melting range of falling and snow accumulation, which is referred to as normal.

However, in severe cold regions, heavy snowfall sometimes causes intense snowfall. Therefore, it is necessary to install a snowfall sensor that detects these weather conditions, and at the same time, it is necessary to plan the road surface by increasing the snowmelt effect.

During heavy snowfall due to the reasons described above, the water spraying method must be temporarily effective, but the water spraying method is susceptible to damage caused by freezing due to the wind and the like on other objects on the road surface,
If the snowmelt water in the non-sprinkling pipe is jetted out of the road as part of snowmelting water, there is no need to worry.

That is, the birth of a snow melting apparatus that can be called a combined snow melting apparatus of a water spray snow melting apparatus and a non-sprinkling snow melting apparatus.

However, when snowfall is severe as a snow-melting device to secure a snow-free road surface, detection of the snowfall sensor activates the solenoid valve and a part of the snow-melting medium water jets out of the road surface to perform efficient snow-melting. There is a need.

 There are the following two methods for the road surface touch jet spill.

1. As shown in Fig. 1, the snow-melting water surface touch jet spill device 4 is installed and operated in an appropriate arrangement directly on the snow-melting pipe to eliminate snow.

2. As shown in FIG. 3, a snow-melting pipe is provided separately from the snow-melting pipe, and the snow-melting water-surface touch jet-outflow device 41 is installed and operated on the snow-melting pipe to eliminate snow.

Here, when organized, the present application is as follows.

A snow-melting water surface touch jet spill device 4 is connected at predetermined intervals to the upper surface of a snow melting pipe 3 meandering on a general road surface 2, and a condition detected by a snowfall sensor 6 is electrically commanded by a control panel 5. Out of contact with the current-closing electromagnetic valve 4A, which is integral with the snow-melting water-surface touch jet spill-out device 4 through the energizing-closing electromagnetic valve operating line 7. The appliance 4 includes a current-closing solenoid valve 4A which is energized according to the weather conditions detected by the snowfall sensor and which is opened and closed by a power failure operation, and a snow-melting water jet fitting which is nozzle-processed so that snow-melting water can be jetted out onto the road surface.

Electromagnetic valve snow melting nozzle connecting pipe 4D and the above-mentioned set of equipment are stored and embedded in the pavement of the road surface. Since it is composed of the equipment storage protection box 4E, each of the snow-melting water surface touch jet spill devices is a snow-melting device that operates simultaneously according to the detection status indication of the snowfall sensor.

 Also, the following can be performed.

A snow melting pipe 31 meandering on the general road surface 2 and a snow removing pipe 311 branched from the starting end of the snow melting pipe 31 via a closed solenoid valve 41A when energized are provided on the upper or lower surface of the snow melting pipe 31 in a meandering manner. Then, a snow-melting water-surface touch jet spill-out device 41 in which a solenoid valve is not stored is connected to the upper surface of the snow-melting pipe 311 at a predetermined interval, and a condition detected by the snowfall sensor 61 is electrically controlled by the control panel 51. At the beginning of the snow melting pipe 31 through the solenoid valve operating line 71 when energized.
In the current-carrying closed solenoid valve 41A, the snow-melting water-surface touch jet spill that does not store the solenoid valve is instructed by the snowfall sensor to detect the situation where the snowfall sensor 41 is detected by the snowfall sensor. In what is configured to be put into operation, the snow-melting water road surface touch jet spill device 41 in which the solenoid valve is not stored, the nozzle hole 41B is machined so that the snow-melting water is touch-spouted on the road surface, A combined snow-melting pipe and non-water-sprinkling snow-melting pipe that are directly attached to the snow-melting pipe 311 and operate in conjunction with the energized closed solenoid valve 41A that opens and closes according to weather conditions detected by the snowfall sensor 61 and that opens and closes due to a power failure operation. It is a snow melting device for piping.

[Operation] The effect will be described.

Embodiment of the Invention FIGS. 1 and 2 show a snow melting apparatus 1 that can be called a non-sprinkling snow melting apparatus. However, it is difficult to secure a snow melting road surface with only a non-sprinkling snow apparatus. This drawing mainly shows an example of an installation method of a snow blasting water surface touch gushing outflow device which is hardly affected by wind and the like and is capable of being squirted out of the road surface.

FIG. 1 relates to a snow melting apparatus 1 in which an appropriate number of snow-melting water-surface touch jet spill devices (integrated with a solenoid valve) are installed directly on a snow-melting pipe installed on a general road surface so that snow can be evenly erased on a snow-covered road surface. is there.

Accordingly, referring to FIG. 2, the snow-melting water road surface touch jet spill device 4A is installed directly in the snow-melting pipe, and is an energized closed solenoid valve 4A that is opened and closed by energizing and de-energizing operations according to the weather conditions detected by the snowfall sensor. And the snow-melting water jet-out fitting 4B having the nozzle hole 4B1 so that the snow-melting water can be jetted out of the road surface.
And 4C of snow-melting water spout fittings to fix the snow-melting water spout fittings properly, and the snow-melting water jet touching spout from the nozzle of the snow-melting water spouting metal fitting through the solenoid valve from the snow-melting pipe. The electromagnetic valve snow melting nozzle connection pipe 4D and the above set of equipment are stored and embedded in the pavement of the road surface, and these are stored on the road surface to improve the protection and snow removal effect. And a protective box 4E.

The snow-melting water surface touch jet spill device 4 is configured to operate in conjunction with weather conditions by a snowfall sensor 6 that is appropriately disposed and arranged in FIG.

The control panel 5 electrically issues a condition detected by the snowfall sensor 6 to the energized closed solenoid valve 4A which is integral with the snow-melting water surface touch jet spill device 4 through the energized closed solenoid valve operation line 7. It is configured to be activated.

In the case of severe snowfall such as heavy snowfall due to the interlocking operation of the above equipment, a part of the non-sprinkling snow melting equipment, which is the main body of the combined snow melting equipment, becomes snow melting water and the snow touches the snow-melting water road surface and the road surface touches from the spouting equipment 4. It erupts and melts down the snow on the road surface to reach drain 2A.

3 and 4 relate to a snow melting apparatus 11 which can be called a combined snow melting apparatus, which has a configuration in which the merits of a non-sprinkling snow melting apparatus and a modified snow melting apparatus are combined. When snowfall is severe due to heavy snowfall where it is difficult to secure a snow-melted road surface using only a water-sprinkling device, a snow-melting water surface touch jet spill device has been modified so that the water sprinkling method to be operated is less affected by wind, etc. The figure mainly shows an example of an installation method.

FIG. 3 shows a general road surface. In addition to a snow-free snow-melting apparatus, a weather-condition obtained by a snowfall sensor is separately provided with a snow-melting pipe 311 which is operated jointly by one energized closed solenoid valve 41A. This figure shows a state in which a snow-melting water surface touch jet spill device 41 is installed in this pipe.

Reference numeral 21 denotes a general road surface, and reference numeral 21A denotes a drainage groove formed in the flow direction of snowmelt water.

Reference numeral 31 denotes a snowmelt pipe which is provided in a meandering state, and groundwater normally flows as a snowmelt medium liquid.

Therefore, referring to FIG. 4, the snow-melting water road surface touch jet spill device 41 has a nozzle hole 41B processed so that snow-melting water can be squirted out on the road surface, and is directly installed in the snow-melting pipe 311. It is connected to an energized closed solenoid valve 41A that is opened and closed by an energization and a power failure operation according to weather conditions detected by the snowfall sensor 61 in FIG.

Electronically controls the situation detected by the snowfall sensor 61
A command is issued at 51, and the current-closing solenoid valve 41A and the snow-melting water-surface-touch-jet device 41 are operated through the current-closing electromagnetic valve operation line 71.

In the case of severe snowfall such as heavy snowfall due to the interlocking operation of the above equipment, a part of the non-sprinkling snow melting equipment, which is the main body of the combined snow melting equipment, becomes snowmelt water and the snowmelt water touches the road surface from the spouting equipment 41. It erupts and melts down the snow on the road surface to reach the drain 21A.

That is, the energized closed solenoid valve 41A is for flowing a part of the non-sprayed snow-melting water to the snow-elimination pipe.

 The snowfall sensor 61 detects a snowfall situation on the road surface.

That is, the snowfall sensor 61 electrically issues a snowfall condition on the road surface with the control panel 51, and the energized closed solenoid valve 41A
A part of the snow-melting medium liquid (groundwater) that is operating without water-sprinkling snow-melting is operated as snow-melting water by the snow-melting pipe.

From the snow-melting water surface touch jet spill-out device 41 installed directly on the pipe, the road surface touch squirts and flows, and the snow on the road surface performs the snow-melting melting operation.

In addition, the amount of snow removal water of snow diverted from the snow melting pipe 31 is
The water is adjusted by the snow removal pipe drainage adjusting cock 311A and drained to the drain 21 together with the snow-melting water.

Further, the remaining snowmelt water in the snowmelt pipe 31 is reduced to the reducing well 81.

The snow-melting water surface touch jet spill devices 4 and 41 are main components of the improved water-sprinkling snow-melting device.

In other words, when groundwater is sprinkled on the road surface due to snow removal, it sometimes scatters due to the wind or the like and adheres to other objects on the road or becomes spray particles and drifts, and in severe cold areas it becomes a haze phenomenon and traffic When a part of the snow-melting medium water of the water-free device is sprayed as snow-melting water on the snow-covered road surface, contact (touch) can be spouted out of the road surface.

 As a result, it is possible to solve the problem as a water spray snow removal device.

FIG. 3 shows a state in which a snow-melting water surface touch jet spill device 41 as shown in FIG. 4 is directly installed on a snow-melting pipe 311, which is a separate pipe on the snow-covered road surface, in addition to the snow-melting pipe 31 of the waterless snow-melting apparatus. Is shown.

[Effects of the Invention] The present invention is configured as described above, and has the following effects.

In severe cold regions, the operation of a snow-melting snow-melting system with less damage to freezing is attempted to secure the snow-melting road surface.However, when heavy snowfall such as heavy snowfall is required, if it is necessary to speedily secure the road surface with no water-sprinkling snow-melting time, be careful. I feel the feeling.

In order to solve such a need, when the snowfall is severe, a water spray type is adopted so that the wind and the like will not cause the mist phenomenon to occur due to the scattered freezing on other objects on the road surface or the scattering of spray particles. A part of the snow-melting medium of the non-sprinkling snow-melting equipment is used as snow-melting water from the snow-melting water-surface-touching / slipping-apparatus to make the surface-touching jet-smelt and the same effect as the water-splashing type is obtained to secure the snow-melting snow surface.

That is, it is a snow melting apparatus with good mutual effect that utilizes only the good points of the non-sprinkling snow melting apparatus and the spray snow melting apparatus.

In addition, in severe cold regions, in order to operate the snow-melting equipment rationally, the sensor that detects the snowfall weather condition and the solenoid valve when energized are operated to operate the snowmelting snow that matches the snowfall. The melted water that has been melted and melted does not re-freeze due to severe cold on the road surface, and flows down to the drain to secure a comfortable snow-melted road surface.

Furthermore, the snowmelt medium water of the non-sprinkling snowmelting system is returned to the return well, which serves as environmental protection for groundwater conservation.
