BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing a basic form of an upper protective machinery room system of a tubular and a simple water supply of the present invention. FIG.

1, the upper protective machinery room system of the present invention includes a tubular housing and a simple water tank, and is formed to surround the tubular housing and the simple water tank, A heat circulation fan 16 for preventing the internal equipment from being frozen by discharging the heat of the ground water pumped from the tubular water tank and the simple water tank to the inside of the housing by being positioned in the inner space of the housing, ).

First, the housing is provided with a bottom portion 10 having a separate bottom surface and a bottom portion 10 extending in the height direction along the circumference of the bottom portion 10 to protect the internal space of the housing from foreign substances such as moisture generated in the ground from the soil A side wall portion 20 having a side surface, and a plate-like roof portion 30 having one side connected to the side wall and covering the upper surface of the housing.

The bottom part 10 is formed with a bottom surface for forming a building on the ground, and its purpose is to form a foundation so that moisture or foreign matter generated on the ground from the soil is not introduced into the internal space. Generally, concrete or synthetic resin flooring used for floor construction can be put in place, and various known materials such as rubber resin or synthetic resin plate can be used as flooring material.

The bottom portion 10 is provided with a through hole 13 on one side thereof so that an upper portion of the tubular pipe 11 extending from the ground to the ground can be penetrated. The tubular pipe (11) connects the pump equipment and the water pipe (12) to the underground water pump in order to pump the ground water to the ground. Therefore, the tubular through-hole 13 is a place where the end of the tubular pipe 11 exposed to the ground is located for pumping the groundwater to the outside of the housing. In addition, the water pipe 12 inside the tubular pipe 11 is formed to extend to the outside of the housing (the position requiring water) through the through hole 13, so that the pumped groundwater can be moved.

However, the tubular through-hole 13, which is the portion where the tubular pipe 11 protrudes to the ground, penetrates to the submergence water in the underground, so that when the foreign matter is introduced, the submerged water is contaminated, The upper part of the orifice inlet 14 may be formed in a plate shape or a curved shape so as to seal the portion protruding to the ground by forming a tubular inlet 14 extending in the height direction along the periphery of the tubular through- It is preferable to cover the circumference of the plate along the circumference of the circumference of the orifice inlet 14 by using the circumferential cover 15 bent at the circumference of the plate and to remove the cover only when necessary so that the inside can be confirmed. The tubular inlet 14 is formed with a first water pipe through-hole 18 through which the water pipe 12 extends to the outside.

The side wall portion 20 extends in the height direction along the circumference of the bottom surface to form a side surface. The side wall portion 20 and the roof portion 30 to be described later may be formed of various materials such as known concrete, brick, plank, plywood or the like that can form a curtain of a certain strength depending on a construction purpose and a situation. A second water pipe through hole 19 is formed in one side of the side wall 20 in a shape corresponding to the end surface of the water pipe 12 so that the water pipe 12 described above can penetrate and extend to the outside. Further, the side wall part 20 can selectively form a doorway on the other side.

The roof portion 30 covers a top surface of the inner space provided by the bottom portion 10 and the side wall portion 20 by a plurality of panels rotatably connected to one side of the side wall portion. However, due to the characteristics of the upper protection machinery room system of the tubular water tank and the simple water supply system, the roof unit 30 can be opened and closed such that the structure of the tubular pipe 11 located in the inner space can be easily performed . Therefore, the roof part 30 is connected to the side of the side wall part 20 through the hinge 31 so as to be rotatable, respectively, so that the roof part 30 can be manually opened and closed by the user.

The heat circulation fan 16 is attached to one side of the water pipe 12 and is pumped from the water pump in the underground water to move the ground water along the water pipe 12. In winter, even when the temperature of the ground falls below minus zero, The term "temperature" refers to a thermo-circulation device that emits the warmth contained in the groundwater to the inner space at one side of the pipe through which the groundwater moves, using the characteristic that the temperature is maintained at a constant room temperature. The thermal circulation fan 16 uses the functions and structure of the geothermal heating system, which is a known technology, and thus a detailed description thereof will be omitted.

The controller 50 receives a measurement signal measured from a sensor included in the system or a control signal transmitted from a user and controls various mechanical devices including the thermo-circulating fan 16 according to the received signal. But it is not limited in its location. The controller 50 will be described in more detail in the following description of the block diagram of the controller 50 to be described later.

With this configuration, a housing for protecting the tubular pipe 11 is formed. By applying a hinge structure to the roof part 30, the tubular pipe 11 can be easily pulled out, and the heat circulating fan 16 can be mounted It is possible to protect internal equipment from cold weather such as frost wave in winter by radiating the warmth of underground water to the inside space.

One end of the folding arm 62 is fixed to the lower portion of the support shaft 20, that is, the side of the bottom portion 10 and the other end is fixedly connected to each of the slanted wall portions 40, In the case of forming a quadrangular pyramid as in the embodiment, it should be connected to the four inclined wall portions 40, and the connecting position in the inclined wall portion 40 is preferably a center of gravity point of the triangle in order to ensure stable durability . At this time, the folding arm 62 may be manually controlled and further include a folding arm driving motor which provides power for automatically folding the folding arm 62. The folding arm driving motor generally refers to a mechanical structure necessary to provide a driving force to the folding arm 62 and includes a motor, a shaft, a bevel gear, and the like so that the folding arm 62 can be folded or unfolded . Since the mechanical configuration is a known concept, it is needless to say that a device other than the above-described configuration may be used, and a detailed description thereof will be omitted.

 The folding arm driving motor and the lightning rod driving motor provide power to perform automatic control in a specific situation through a lightning rod ascending / descending module 54 and a folding arm control module 57 of a controller 50, which will be described later, Even if each motor is not driven, it is possible to manually control the motor at will.

In the folded state, the inner space is sealed to provide warmth, The inclined wall portion 40 is formed so as to touch the ground so that the openness is maximized.

In addition, the inclined wall portion 40 may be provided with a mounting groove 41 so as to be easily mounted on the folding arm 62. The mounting groove 41 is formed in the inclined wall portion 40, When the folding arm 62 is realized as a vertex extending outwardly, that is, in a three-dimensional shape, a portion where the slanting wall 40 and the folding arm 62 abut each other is rounded. When the inclined wall portion 40 is folded in a three-dimensional shape due to the provision of the mounting groove 41, the physical structure of being closely coupled with the folding arm 62 is realized, so that the inner tank and the simple water line can be more stably protected .
