Description

Technical Field

[0001] This utility model relates to the field of excavator technology, and in particular to a photovoltaic device for excavators. Background Technology

[0002] With the advancement of industrialization, excavators are needed for engineering assistance in various projects. However, the following problems exist when they work in hot environments:

[0003] 1. In hot regions such as Africa, where local oil prices are high, the existing excavator air conditioners are powered by generators generated by the engine when the excavator is working. However, this increases the excavator's fuel consumption, causing operators to often hesitate to use the air conditioner for cooling. Utility Model Content

[0004] In order to solve the above problems, the purpose of this utility model is to provide a photovoltaic device for excavators, which solves the problem that existing excavator air conditioners need to consume oil from the fuel tank.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A photovoltaic device for an excavator includes a housing, an outdoor air conditioning unit fixed behind the housing, an indoor air conditioning unit inside the housing, and a solar power supply component mounted on the housing for supplying power to the air conditioning unit.

[0007] The solar power supply assembly includes a horizontal frame fixed to the outer casing, a solar panel fixed within the horizontal frame, a battery fixed to the outer casing and below the solar panel, a solar controller fixed to the outer casing, a first connecting wire fixed to the solar controller for electrically connecting the solar panel, a second connecting wire fixed to the solar controller for electrically connecting the battery, and a third connecting wire fixed to the solar controller for electrically connecting the indoor unit of the air conditioner.

[0008] More preferably, a limiting hole plate is fixedly provided on the rear part of the outer shell, and the third connecting line is disposed through the limiting hole plate.

[0009] More preferably, the rear side of the housing is provided with a wire hole, the middle section of the third connecting wire is inserted into the housing along the wire hole, and the indoor unit of the air conditioner is fixedly provided with a pipe that extends out along the wire hole and is connected to the outdoor unit of the air conditioner.

[0010] More preferably, an elastic sealing ring is fixed inside the thread hole.

[0011] This utility model has the following beneficial effects:

[0012] 1. This utility model converts sunlight into electricity through a solar power supply component when the excavator is exposed to sunlight during use, so that the excavator's on-board air conditioner can be powered by sunlight, thus solving the problem that existing excavator air conditioners need to consume oil from the fuel tank during use.

[0013] 2. This utility model solves the problem that the third connecting wire, which is placed outside the outer casing, is prone to drifting and thus affects the operation of the excavator by setting up a wire hole to limit and fix the third connecting wire.

[0014] 3. This utility model uses a wire hole to house the third connecting wire and conduit, and wraps the third connecting wire and conduit with a sealing ring to maintain a sealed environment inside the casing as much as possible, preventing cold air from escaping and causing power waste.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, a photovoltaic device for an excavator in this embodiment includes a housing 1, an outdoor air conditioning unit 2 fixed behind the housing 1, an indoor air conditioning unit 3 disposed inside the housing 1, and a solar power supply component 4 disposed on the housing 1 for supplying power to the air conditioning unit.

[0022] The solar power supply assembly 4 includes a horizontal frame 41 fixed to the outer casing 1, a solar panel 42 fixed inside the horizontal frame 41, a battery 43 fixed to the outer casing 1 and below the solar panel 42, a solar controller 44 fixed to the outer casing 1, a first connecting wire 45 fixed to the solar controller 44 and used for electrically connecting the solar panel 42, a second connecting wire 46 fixed to the solar controller 44 and used for electrically connecting the battery 43, and a third connecting wire 47 fixed to the solar controller 44 and used for electrically connecting the indoor unit 3 of the air conditioner.

[0023] When using this product, the excavator is placed under sunlight, causing the sunlight to shine on the solar panel 42. The solar panel 42 converts the light energy into electrical energy, which is then transmitted to the solar controller 44 via the first connecting line 45. The solar controller 44 determines and controls the flow of electrical energy. When the indoor unit 3 is not running, the solar controller 44 drives the electrical energy through the second connecting line 45 into the battery 43 for storage. When the indoor unit 43 is in use, the electrical signal is transmitted to the solar controller 44 via the third connecting line 47, which in turn drives the solar controller 44 to control the electrical energy in the battery 43 to be input into the indoor unit 3 via the second connecting line 46, the solar controller 44, and the third connecting line 47 for use by the indoor unit 3.

[0024] Therefore, compared with the existing method of using diesel fuel consumed by the engine to power the indoor air conditioning unit 3, the operation of the indoor air conditioning unit 3 is separated from the engine and powered solely by the solar power supply component 4. This solves the problem of the need to consume diesel fuel for the use of air conditioning. At the same time, when the excavator is not in use, the indoor air conditioning unit 3 can still be powered by the solar power supply component 4, so that the air conditioning can be used without starting the engine, further saving diesel fuel consumption.

[0025] like Figure 1 and Figure 2 As shown, a limiting hole plate 5 is fixedly provided on the upper rear part of the outer shell 1, and the third connecting line 47 is set through the limiting hole plate 5.

[0026] When using this product, the middle section of the third connecting line 47 is passed through the limiting hole plate 5, so that the third connecting line 47 is limited and pulled by the limiting hole plate 5, thereby preventing the third connecting line 47 from drifting naturally and causing problems that affect the excavator's operation.

[0027] like Figure 1 and Figure 2 As shown, a wire hole 6 is provided on the rear side of the outer casing 1. The middle section of the third connecting wire 47 is inserted into the outer casing 1 along the wire hole 6. The indoor unit 3 of the air conditioner is fixedly provided with a piping 7 that extends out along the wire hole 6 and is connected to the outdoor unit 2 of the air conditioner.

[0028] When this product is in use, the indoor unit 3 of the air conditioner is powered by the battery 44 through the third connection line 47, and the power is shared with the outdoor unit 2 of the air conditioner through the piping 7.

[0029] like Figure 1 and Figure 2 As shown, an elastic sealing ring 8 is fixed inside the thread hole 6.

[0030] When using this product, the sealing ring 8 is designed to fit as snugly as possible around the outer wall of the third connecting line 47 and the pipe 7 that extend into the housing 1, thereby minimizing the outflow of cold air from the housing 1.

[0031] The working principle of this device is as follows:

[0032] Step 1: When the excavator is working outdoors, sunlight shines on the solar panel 42, which converts light energy into electrical energy and inputs it into the solar controller 44 through the first connection line 45. The solar controller 44 determines whether the air conditioner indoor unit 3 is turned on, and then inputs the electrical energy into the battery 43 through the second connection line 46 for energy storage.

[0033] Step 2: When the operator is sitting inside the excavator and the indoor air conditioner unit 3 is turned on, the electrical signal is transmitted to the solar controller 44 through the third connecting line 47. This causes the solar controller 44 to transfer the electrical energy in the battery 43 through the second connecting line 46 and then through the third connecting line 47 to the indoor air conditioner unit 3 for use. This allows the outdoor air conditioner unit 2, which is connected to the indoor air conditioner unit 3 through the piping 7, to be driven by the electrical energy provided by the battery 44, thus causing the air conditioner to operate.

[0034] The above description is only a specific embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
