2. Description of the Related Art As a method for securing an initial ventilation path, an initial ventilation method has been used in which a profile is temporarily placed on a finished floor surface and air is allowed to flow therethrough, or a drainage groove is provided to use the interior of the profile.

In this method, the load air supply duct is a branch from the pillow duct and blows into the accumulated snow bottom. In this method, it was difficult to evenly distribute the air to the individual heat exchange ventilation holes. Moreover, it was not easy to correct the difference in growth of the heat exchange ventilation passage. In addition, it was not suitable to intentionally adjust the air volume for each individual wind passage.

[0004]

A flat floor for large-scale snow storage,
Eliminating temporary objects for ventilation. Initial open air passage of open type melt water guide without lid. Ventilation adjustment for each airway row. Can be used for both automatic control and manual operation. It is easy to open the reopening hole when the airway is accidentally closed. Be able to detect the ventilation status of each ventilation passage.

[0005]

[Means for Solving the Problems] By installing fine molten water guide grooves for work in a snow storage or a snowy area that does not fit heavy equipment vehicle tires at intervals that do not spread too much, there is no slope on the floor surface. However, the molten water does not accumulate on the floor, but flows into the water channel and serves the initial purpose of draining water.

[0006] The snow in the water guiding groove, which is clogged when the snow is carried in, is melted by the water flow, and the water guiding groove serves as an initial ventilation hole. Therefore, it is not necessary to secure an initial opening with a temporary object. Since the narrow water guiding groove does not cause an obstacle such as a vehicle tire getting stuck, a lid such as a grating is not required.

[0007] A duct with a damper is installed for each row of heat exchange air passages in the bottom of the snow accumulation to ensure separate air supply. The damper operation is a simple function of fully open and fully closed, and there is no difference between automatic control and manual operation. A double row of dampers was arranged in one ventilation passage, and the individual dampers were adjusted by simply operating them to fully open and close them.

The individual wind passages are equipped with detection of the air volume and the wind pressure to detect the diameter growth of the heat exchange ventilation holes at the bottom of the stored snow and to detect the situation of the passing air flow in case of accidental blockage.

Since the opening of the initial ventilation passage is also used as the molten water guide groove, the blockage of the ventilation hole due to collapse can be restored by re-spraying the water guide groove.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Explaining the embodiment of the present system with reference to the drawing A, an adiabatic snow storage 1 stores snow storage 3 which is a cold heat source. A water guiding groove 7 is formed on the floor of the snow storage, and a water collecting groove 8 is formed therein to serve as a suction path for cold air. The sorting duct 6 is arranged above the water guiding groove 7,
Each is equipped with a damper 5. Each of the sorting ducts is connected to the main air passage 4 and is supplied with load air. Similarly, a water discharge pipe 11 is provided on the upper side of the water guiding groove 7 to melt the snow stuck in the water guiding course. Further, a detector 12 for air volume and pressure is installed in the air passage to detect an abnormality in the heat exchange vent hole 10.

Further, there is a heat insulating cabinet 1 for storing the cold heat source, a doorway 2 for carrying in the cold heat source, and a water guiding groove 7 and a water collecting groove 8 on the floor. The water collecting groove 8 is provided with a grating 9, and the water guiding groove 7 is an open groove. The width of the water guiding groove 7 is a narrow groove that does not fit the tire of the work vehicle in the refrigerator, and an arbitrary number is secured on the floor surface. At the upper part of this water guiding groove, there is a sorting duct 6, which is equipped with a damper 5, which separates the loaded air from the main air duct 4 and supplies the loaded air to the water guiding groove 7. Further, a water discharge pipe 11 is installed above the water guiding groove, and when the snow and ice that is a cold heat source is carried in, the snow and ice in the water guiding groove that is filled up is melted by discharging water, and the inside of the water guiding groove is used as an initial load air ventilation hole. To do. Due to the heat exchange of the load air passing through the water guide groove, the stored snow 3 in the storage grows into a tunnel of the load air circulating air as shown by the dotted line. Due to the balance of development, this tunnel diameter is settled by the weight of the accumulated snow, and the tunnel diameter is narrowed. During the repetition of the repetition, if there is a difference in growth between the tunnel diameters and a significant difference in ventilation occurs, this is detected by the air volume and air pressure detector 12 to increase the load air supply to the narrowed tunnel. Is controlled. When the tunnel is closed due to the collapse of the accumulated snow, water is arbitrarily discharged from the water discharge pipe 11, the ventilation holes are regenerated and restored to grow into a heat exchange ventilation tunnel.

[0012] The load air supply duct is equipped with a damper for restricting the air flow so that the air flow is controlled against a significant deviation of the air flow due to the deviation of the ventilation snow holes. All ducts are usually half
Ventilation at the opening degree circulates the required air volume.However, when the balance of the air volume in each air hole is disturbed due to the unevenness of the snow openings, the ventilation holes with excessive air volume fully close the damper. ,
The dampers are fully opened in the ventilation holes with an excessively small air volume, and the passage of the load air volume is adjusted, and each ventilation hole constantly exchanges heat with an equal amount of ventilation to promote balanced growth of the ventilation holes.

The water discharge device provided above the water guiding groove is useful not only for the purpose of opening the air holes but also for cleaning the molten water guiding groove for cleaning the inside of the chamber during the empty period. Water discharge can be controlled for each water guide groove, making it easy to check the opening of each water guide groove.

[0014]

[Effects of the Invention] The floor construction and finish of the cold and heat source snow storage are simple, the flatness facilitates the operation of the vehicle, and when the vacancies are available, it is flat and can be stacked with a versatile pallet. Becomes The open water conduit has good workability in removing foreign matter from mud. If systematic equipment is installed in the ventilation openings, human work can be reduced.

By making the installation width of the narrow water guide groove not too wide, even if the floor is finished flat, the drainage of the melted water is good, and the floor fabrication finish becomes easy. Since the vehicle is flat, the vehicle is easy to operate, and the flatness is good even when pallets for other purposes or packing loads are stacked in the vacant period. The open type water conduit has a good working environment for removing foreign matter from mud. It is easy to use automation and manual operation for the ventilation hole water discharge device and the air volume control damper.
