Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a storage structure that can easily and compactly store a refrigeration device having a private power generation facility without exposing the electrical wiring.

(Prior art) This is a structure in which refrigeration equipment such as a refrigerated container is housed together in a casing, and there are not only a large number of electrical wires that connect the electrical equipment for the refrigeration equipment and the electrical parts box, but also a wiring route. In the case of long and diverse wiring, it is difficult to perform this wiring process efficiently, especially in the case of a refrigeration system with power generation equipment, which houses the power generation equipment, electric parts box for the refrigerator, etc. Many types of equipment are arranged inside the mechanical unit room, and laying the required wiring within the narrow space is a rather troublesome task.

By the way, in conventional refrigeration systems, the hollow part of a cradle as disclosed in Japanese Utility Model Application Laid-open No. 57-49685 was used as a storage space for arranging connecting wires.

As shown in FIG. 4, this pedestal is constructed by fixing a supporting frame 41 formed in a gate shape with pipes in parallel on both sides, and attaching a horizontal beam 43 continuous to the upper ends of the pillars 42, 42 at both ends. It is formed to support an exchanger, etc., and in that case, the electrical wiring 30 to the fan motor for the heat exchanger is arranged in the support frame 41 made of pipes, and each electrical equipment is connected to the support frame 41. The hollow frame of the supporting pedestal was used as a wiring duct.

(Problems to be Solved by the Invention) The conventional structure described above is a method in which the wires are drawn out in the pipe, holes are made for the wires to be drawn in, and the wires are inserted into the pipe, so it is quite troublesome to insert and remove the wires. In most cases, wiring cannot be done without using a call line, resulting in the problem of a large amount of man-hours and time spent on construction work.

Furthermore, if you try to pull out the refrigeration equipment from the casing for inspection, etc., you will need to pull out the electrical wiring as well, so you will have to disconnect and connect the wiring terminals each time. It was a hassle without it.

In addition, instead of inserting the wire inside the pipe, it is possible to fix the wire along the outer circumference of the pipe, but this will expose most of the wire and cause damage to the insulation coating during inspection and service. This is not desirable due to safety issues.

The present invention was developed with attention to these points, and in particular, the central frame provided to partition the mechanical unit room, heat source unit room, and usage unit room can be used to store electrical wiring. By having a unique shape with a pocket, it can be used commonly as a wiring duct that can be easily taken in and out, solving the conventional problems mentioned above, making wiring processing easier and improving safety. The purpose of this invention is to achieve this goal.

(Means for Solving the Problems) Therefore, the present invention partitions the inside of the casing 1 into upper and lower parts by a central frame 19 installed horizontally in the middle, and the lower chamber is divided into the engine 12, the generator 11, and the electric parts for the refrigerator. The refrigeration system is formed into a mechanical unit chamber 4 that houses a box 10, etc., and an upper chamber that is formed into a heat source unit chamber 2 that houses a compressor 5, a condenser 6, etc., and a utilization unit chamber 3 that houses a cooler 8, etc. In the device, the central frame 19 is made of a steel material with a modified cross-sectional structure, and this steel material is used to form a Z-shaped substrate 21 consisting of a bottom plate portion 22, an intermediate partition plate portion 23, and a top plate portion 24.
, an upright side plate part 25 and a hanging side plate part 26 extending from both ends and bent at a right angle to the side facing the intermediate partition plate part 23, and a middle part extending from the lower end of the hanging side plate part 26. Partition plate part 23
The central frame 19 has a receiving plate portion 27 bent at right angles by an appropriate length to maintain a gap, and a compressor motor, a fan, etc. Refrigerator electrical equipment such as a motor, solenoid valve, etc. and the refrigerator electrical equipment box 1
It is characterized by housing electric wiring 30 that connects between 0 and 0.

(Function) The pocket above the receiving plate portion 27 in the central frame 19 is connected to the receiving plate portion 27 over its entire length in the longitudinal direction.
Since there is a gap on the side where the electrical wiring 30 can be taken in and out, it is very easy to store and draw out the electrical wiring.In addition, the wiring can be partially secured to the receiving plate part 27 using a clip or the like. Fixation is easily and reliably achieved.

Further, since the central frame 19 has a modified cross-sectional structure, its load-bearing strength increases and it can stably support heavy objects.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

FIG. 1 shows a refrigeration system for a refrigerated container according to an example of the present invention, in which the inside of a casing 1 is partitioned into two levels vertically by a central frame 19, and the upper chamber is further divided into two left and right chambers to form three chambers. The upper right chamber is a heat source unit chamber 2, the upper left chamber is a utilization unit chamber 3, and the lower chamber is a mechanical unit 4.

The heat source unit room 2 houses a compressor 5, an air-cooled condenser 6, a fan 7, etc., and the usage unit room 3 houses a cooler 8, such as an evaporator, a fan 9, a drain pan 18 (see Figure 3), etc. are doing.

On the other hand, the mechanical unit room 4 contains a refrigerator electrical parts box 10, a generator 11, an engine 12, and a radiator 1.
3. Refrigerator electrical parts box 1 that houses the fan 14, fuel tank 15, storage battery 16, generator electrical parts box 17, etc., and is attached to the frame of the casing 1.
Each device other than 0 is mounted and fixed on a common pedestal 20 so that it can be taken in and out of the casing 1 all at once.

The above-mentioned refrigeration system is capable of performing refrigeration operation by energizing the compressor 5 and each of the fans 7, 9, and 14 using private power generation, and is integrated by attaching the rear side to a container van (not shown). Assemble.

In the refrigeration system having the structure described above, the central frame 19 provided to partition the inside of the casing 1 into upper and lower parts is made of a steel material with an irregular cross-sectional structure, as shown in FIGS. , this steel material is attached to both ends of the intermediate partition plate part 23, that is, the bottom plate part 22 and the top plate part 24, with respect to the Z-shaped substrate 21, which consists of a bottom plate part 22 and a top plate part 24, which are bent and extended at right angles in opposite directions from both ends of the intermediate partition plate part 23. The intermediate partition plate portions 23 are bent at right angles in opposite directions from the ends of the intermediate partition plate portions 23.
An upright side plate part 25 and a hanging side plate part 26 are provided which extend so as to face each other, and the lower end of the hanging side plate part 26 is bent at a right angle to the intermediate partition plate part 23 side. On the other hand, the receiving plate part 27 is provided with an appropriate length that can maintain the gap, for example, about half the width of the top plate part 24.

Therefore, the recess that opens upward by the intermediate partition plate part 23, the bottom plate part 22, and the upright side plate part 25 is also opened by the intermediate partition plate part 23, the top plate part 24, the hanging side plate part 26, and the receiving plate part 27. As a result, a pocket portion is formed in which half the width of the bottom portion is opened downward.

In this pocket, a portion above the receiving plate portion 27 surrounded by three sides, top, bottom, and sides, serves as a storage space for electrical wiring, while the concave portion and the top plate 27
The upper surface side is the base of the heat source unit chamber 2 and the utilization unit chamber 3, and the compressor 5, which is a heavy object, is mounted on the heat source unit chamber 2 side, and the base must be flat. An angle steel 28 is fitted into the recess to create a high-strength structure.On the other hand, the drain pan 1
8 is mounted, and the space between this drain pan 18 and the central frame 19 is filled with a heat insulating material 29 to cut off the heat drying area between the usage unit room 3 and the mechanical unit room 4. .

As schematically shown in FIGS. 1 and 2, the pocket above the receiving plate 27 of the central frame 19 has a
For connecting the compressor 5 motor, fan 7 motor, solenoid valve, pressure switch, etc. in the heat source unit room 2 to the control equipment in the refrigerator electrical parts box 10 in the mechanical unit room 4. The electrical wiring 30 is stored and stretched in a bundled state.

The bundled electrical wiring 30 can be fixed in the pocket by securing it with a band or the like with an appropriate gap, and by securing it to the receiving plate part 27 with a clip made of an insulating material. In addition, the top plate part 2
4 and leading into the heat source unit chamber 2, the penetration part of the electrical wiring 30 is airtight, thermally insulated, and electrically insulated by interposing a rubber bushing in the through hole. Processing is possible.

(Effects of the invention) As is clear from the above, the invention has the following effects:
The central frame 19 is made of a steel material with an irregular cross section made of Z-shaped steel material, and the pocket above the receiving plate portion 27 is used as a storage area for the electrical wiring 30, so that the electrical wiring 30 can be stored without exposing it. It can be stored in a closed state.

Furthermore, since a gap exists in this pocket on the side of the receiving plate part 27 over the entire length of the central frame 19 in the longitudinal direction, it is easy to insert and remove the electrical wiring 30.

Further, the central frame 19 is different from a simple flat plate structure, and has an intermediate partition plate part 23 extending in the loading direction, an upright side plate part 25, and a hanging side plate part 26.
It also has the advantage of having excellent load-bearing strength and being able to stably support heavy objects such as the compressor 5.
