Abstract

This creation system includes a refrigeration device, a fuel power device, an electric motor device and a dual power collection device. The fuel power plant includes an interconnected fuel engine and a centrifugal clutch. The double power collecting device is connected in parallel with the refrigeration device, the fuel power device and the electric motor device. Thereby, when the electric motor device drives the refrigeration device through the dual power collecting device, the fuel power device is idling because the centrifugal clutch is in a disengaged position. When the fuel engine reaches a predetermined rotational speed to cause the centrifugal clutch to change from a disengaged position to an engaged position, and then drive the refrigeration device through the dual power collecting device, the electric motor device is idling. Therefore, this case has the advantages of simple operation and control, low starting resistance of the fuel engine, and direct input of power to reduce the loss of energy conversion.

Description

Dual power refrigeration system

This creation is related to a dual-power refrigeration device, especially a dual-power refrigeration device that can operate independently, with simple control, low start-up resistance of the fuel engine, and direct input of power to reduce the loss of energy conversion.

In principle, the traditional freezer warehouse mainly focuses on frozen vegetables/fruits/meat and other fresh products. Because it is fresh, as long as it loses the freezing, it may damage or reduce the quality. Therefore, the freezer warehouse is usually frozen for 24 hours. All refrigeration units are equipped with an emergency generator, which can be automatically started in the event of a power failure, and then generate electricity to drive the motor of the compressor of the refrigeration unit. However, when there is a power failure, the traditional method is to immediately start the emergency generator (usually a diesel generator). If a small diesel generator is used, some outputs are 12V DC. In this case, it is necessary to convert the DC power first. It can be used only if it is converted into alternating current and boosted to single-phase 110V (or single-phase 220V). Overall, it is quite troublesome and the loss of energy conversion is high. Secondly, if a large diesel generator is used, although it is possible to directly output AC power of single-phase 110V (or single-phase 220V), the equipment cost of large diesel generators is high, the volume is large, and there is also the problem of high energy conversion loss. . In addition, if the above-mentioned motor for driving the compressor is a three-phase motor, it is more troublesome, and equipment for converting into three-phase alternating current is required, which is another problem and additional cost. In view of this, it is necessary to develop a technology that can solve the above-mentioned conventional shortcomings.

At this time, the dual power collecting device drives the electric motor to run idly through the electric transmission assembly.

A fuel powered device 20 is indirectly connected to the compressor 11 . The fuel powered device 20 includes a fuel engine 21 , a centrifugal clutch C and a fuel transmission assembly 22 . The fuel engine 21 is connected to and transmits the centrifugal clutch C. The centrifugal clutch C has at least a disengaging position P1 (see Figs. 4A and 4B ) and an engaging position P2 (see Figs. 5A and 5B ), and The centrifugal clutch C at least includes a clutch input portion C1 and a clutch output portion C2. The fuel transmission assembly 22 is provided with a fuel transmission member 221 and a fuel transmission connection member 222 connected thereto. The clutch input portion C1 is connected between the fuel engine 21 and the centrifugal clutch C; the clutch output portion C2 is connected between the centrifugal clutch C and the fuel transmission member 221 . When the rotational speed of the fuel engine 21 is higher than a predetermined rotational speed, the centrifugal clutch C is shifted from the disengaging position P1 to the engaging position P2, and vice versa from the engaging position P2 to the disengaging position P1. An electric motor device 30 is indirectly connected in parallel with the compressor 11 and the fuel transmission connecting member 222 . The motor device 30 includes an electric motor 31 and an electric drive assembly 32 . The electric transmission assembly 32 is provided with an electric transmission element 321 and an electric transmission connecting element 322 ; the electric motor 31 is connected with the electric transmission element 321 . A pair of power collecting devices 40 are connected in parallel with the compressor 11 , the fuel transmission connection member 222 and the electric transmission connection member 322 . The dual power collecting device 40 has a first transmission part 41 and a second transmission part 42; the fuel transmission connecting member 222 is assembled on the first transmission part 41; the electric transmission connecting member 322 is assembled in the first transmission part 41 The second transmission part 42 . Therefore, when the electric motor 31 is started, the compressor 11 is transmitted through the electric transmission component 32 and the second transmission part 42, thereby driving the refrigerating device 10. At this time, the centrifugal clutch C is normally located at the separation position P1, The dual power collecting device 40 drives the centrifugal clutch C to idle through the fuel transmission assembly 22 . And when the electric motor 31 is turned off, the fuel engine 21 is started, and when the rotational speed causes the centrifugal clutch C to change from the disengaging position P1 to the engaging position P2, the fuel transmission assembly 22 and the first transmission part 41 are used to drive the centrifugal clutch C. The compressor 11 then drives the refrigerating device 10 . At this time, the dual power collecting device 40 drives the electric motor 31 to run idly through the electric transmission assembly 32 . In practice, referring to FIGS. 4A and 4B , the centrifugal clutch C may further include a plurality of centrifugal bodies C3 , a transmission casing C4 and a plurality of springs C5 . In addition, the fuel engine 21 has an output part (the type is not limited, not shown in the drawing, and will be described first). The clutch input portion C1 is connected between the output portion of the fuel engine 21 and the center position of the plurality of centrifugal bodies C3. The clutch output C2 is connected between the transmission housing C4 and the fuel transmission member 221 . The clutch input portion C1 and the clutch output portion C2 are coaxial with each other, and the plurality of centrifugal bodies C3 are respectively erected in the transmission housing C4. Each spring C5 of the plurality of springs C5 is connected between two adjacent centrifugal bodies C3 of the plurality of centrifugal bodies C3. A separation distance G is maintained between the plurality of centrifugal bodies C3 and the transmission casing C4 in a normal state, so that the centrifugal clutch C is normally located at the separation position P1. Thereby, when the fuel engine 21 starts up to a predetermined speed (for example, 1000 rpm), the plurality of centrifugal bodies C3 are pushed away due to centrifugal force (the springs C5 are pulled apart by the adjacent two centrifugal bodies C3 to separate them). generate elastic force) and contact the transmission housing C4, so that the centrifugal clutch C is shifted from the disengaged position P1 to the engaged position P2 (as shown in Figs. 5A and 5B). And when the fuel engine 21 is lower than the predetermined speed, each of the aforementioned springs C5 generates elastic force to pull the aforementioned two adjacent centrifugal bodies C3 back to their original positions, so that the centrifugal clutch C returns from the engagement position P2 to the Separation position P1. Both the fuel transmission element 221 and the electric transmission element 321 are one of a belt pulley and a gear disk. When the fuel transmission member 221 and the electric transmission member 321 are both belt pulleys. Therefore, both the fuel transmission connection member 222 and the electric transmission connection member 322 are transmission belts. And the first transmission part 41 and the second transmission part 42 are both belt grooves. When the fuel transmission member 221 and the electric transmission member 321 are both gear plates. Then the fuel transmission connecting member 222 and the electric transmission connecting member 322 are both transmission chains. And the first transmission part 41 and the second transmission part 42 are both gear plates. Referring to Figures 2B and 3B, the difference between the second embodiment of the present creation and the first embodiment is only: The motor arrangement 30 may further include the centrifugal clutch C. In addition, the motor 31 has an output part (the type is not limited, not shown in the drawings, and will be described first). The clutch input portion C1 is connected between the output portion of the electric motor 31 and the center position of the plurality of centrifugal bodies C3. The clutch output C2 is connected between the transmission housing C4 and the motor transmission member 321 . Similarly, when the rotational speed of the electric motor 31 is higher than a predetermined rotational speed (for example, 1000 rpm), the centrifugal clutch C changes from the disengaging position P1 to the engaging position P2, and drives the electric transmission assembly 32, and vice versa from the engaging position P2 transitions to the separation position P1. The present invention (regardless of the first embodiment or the second embodiment) is mainly applied to the refrigerated warehouse 90. In principle, the frozen vegetables/fruits/meat are mainly used, so the refrigerating device 10 can hardly lose the refrigerating effect. The point is that the freezing device 10 can be switched between the following two types of power, which can greatly reduce the problem of power loss (freezing effect): [a] Electric power mode: In daily life, the refrigeration device 10 is mainly powered by electric power. At this time, the electric motor 31 is started, and the compressor 11 is driven through the electric transmission component 32 and the second transmission part 42 to drive the compressor 11 . The refrigerating device 10 produces a refrigerating effect on the refrigerating warehouse 90; At this time, the centrifugal clutch C set on the fuel power device 20 is normally located at the separation position P1, and the dual power collecting device 40 drives the centrifugal clutch C to idle through the fuel transmission assembly 22, without affecting the transmission of the electric motor device 30. [b] Fuel mode: When the power failure causes the motor 31 to be turned off (of course, other devices can be set to detect whether it is a real power failure or an overload trip, this part is not the focus of this case and will not be repeated), then the fuel engine 21 will automatically Start, and when reaching a predetermined rotational speed (for example, 1000 rpm) to cause the centrifugal clutch C to change from the disengaging position P1 to the engaging position P2, the compressor 11 can be driven through the fuel transmission assembly 22 and the first transmission part 41, namely The refrigerating device 10 can be driven to produce the refrigerating effect on the refrigerating warehouse 90 in the shortest time. At this time, the dual power collecting device 40 drives the motor 31 to idle through the electric transmission assembly 32 (it may also be the second embodiment, the centrifugal clutch C that drives the motor device 30 idles), which also does not affect the fuel power device 20. transmission. The advantages and effects of this creation can be summarized as follows: [1] Simple operation control is possible independently. In this invention, a dual power collection device is provided, and the first transmission part and the second transmission part drive the compressor in a "parallel" manner, that is, one of the power modes can be switched to operate independently to output power, which is quite convenient. Therefore, it is possible to operate independently and control easily. [2] The starting resistance of the fuel engine is small. The fuel engine and electric motor of this creation are designed to operate independently. When the power supply is normal, only the electric motor is running, and the fuel engine does not need to be started; when the power is off, the fuel engine is started. When the speed of the fuel engine does not exceed the predetermined speed, the centrifugal clutch remains in the "disengaged" state; until the fuel engine runs out. After the rotational speed reaches (or exceeds) the predetermined rotational speed, the centrifugal clutch becomes "engaged". That is, the oil-fired engine is not connected to the compressor at low rotation speed, and the starting resistance is small and can be started smoothly. In other words, only connect and drive the compressor when the output speed of the fuel engine is high enough. Therefore, the starting resistance of the fuel engine is small. [3] Direct input of power reduces the loss of energy conversion. The output power of the fuel engine of this creation is to directly drive the compressor, which solves the problem of the traditional emergency generator. The fuel engine first generates electricity, and then connects the electricity to the motor that drives the compressor, and finally drives the compressor indirectly. Therefore, the direct input of power reduces the loss of energy conversion. The above is only a detailed description of the present invention by means of the preferred embodiment, and any simple modifications and changes made to the embodiment do not depart from the spirit and scope of the present invention.
