Description

Technical Field

[0001] The utility model relates to the technical field of glass heat preservation, in particular to an excavator glass with a heat preservation structure. Background Art

[0002] Glass is an amorphous inorganic non-metallic material, which is generally made of a variety of inorganic minerals as the main raw materials, and a small amount of auxiliary raw materials. Its main components are silicon dioxide and other oxides. The chemical composition of ordinary glass is Na2SiO3, CaSiO3, SiO2 or Na2O·CaO·6SiO2, etc. The main component is silicate complex salt. It is an amorphous solid with irregular structure, widely used in buildings to block wind and transmit light, and is a mixture.

[0003] The glass installed on the existing excavators lacks the performance in heat preservation. In the hot summer, the excavator not only has to work continuously under high temperature, but also needs to withstand direct sunlight. This strong sunlight will rapidly increase the temperature in the cab, making the driver feel very uncomfortable during operation, and may even suffer from heat stroke. In the cold winter, the excavator needs to work in a low temperature environment. If the glass on the excavator does not have good heat preservation performance, the temperature of the cab will become very low, and the driver may feel very cold during operation, which will not only affect work efficiency, but also may affect the driver's health.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

The rotation of the motor 10 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives a number of fan blades 11 to rotate. Air is sucked in from the air inlet 2 on the side of the shell 1 and blown downward through the air guide plates 12 through the fan blades 11. Air is continuously blown along the edge of the glass 7 to form an air barrier, reducing the heat exchange between the glass 7 and the air inside the cab. The aerogel 8 bonded between the glass 7 and the thermal insulation film 3 bonded to one side of the glass 7 further reduce air heat exchange and heat radiation from the sun.

[0024] Furthermore, a groove 16 is provided inside the mounting ring 4 for clamping the glass 7 .

[0025] Furthermore, the side surface of the glass 7 is slightly curved, so as to match the bending angle of the opening 15 where the glass 7 of the excavator cab is installed.

[0026] Furthermore, a plurality of openings 15 are formed at the four corners of the mounting ring 4 , and heat-conducting columns 14 identical to the openings 15 formed on the mounting ring 4 are fixed at the four corners of the heat-conducting ring 6 , and the heat-conducting columns 14 pass through the openings 15 to conduct heat away.

[0027] Furthermore, cylindrical protrusions are provided at both ends of the air guide plate 12 , which not only clamp the air guide plate 12 at the bottom of the housing 1 , but also facilitate the adjustment of the angle of the air guide plate 12 .

[0028] Furthermore, a vacuum cavity 9 is provided between the aerogels 8 to reduce heat exchange between the glass 7 on both sides.

[0029] Working principle: The structure of the excavator insulation glass 7 mainly includes the following components: multiple main glass 7, and a layer of aerogel 8 material is tightly attached to the opposite side of the glass 7. In order to reduce the heat exchange of the overall structure, a sealing ring 13 is installed around the glass 7 component. The outer periphery of the sealing ring 13 is further equipped with a heat conducting ring 6, and the outer side of the heat conducting ring 6 is surrounded by a mounting ring 4. The structure of the mounting ring 4 is specialized to adapt to the connection of the shell 1. The side of the shell 1 is designed with a number of air inlets 2, and the bottom is equipped with a wind deflector 12. The fan blades 11 are located inside the shell 1, above the wind deflector 12, and are arranged in a ring. A rotating shaft 5 is fixed at the center, one end of which is connected to the output end of the motor 10. When the motor 10 is running, it will drive the rotating shaft 5 to rotate, thereby driving the fan blades 11 to rotate together, and inhale air from the air inlet 2 on the side of the shell 1, and blow it downward through the wind deflector 12. The air flow forms a continuous air barrier along the edge of the glass 7, which significantly reduces the heat exchange between the glass 7 and the interior of the cab. In order to enhance the heat preservation effect, not only the aerogel 8 layer is bonded between the glass 7, but also the heat insulation film 3 is bonded on the other side of the glass 7. The combination of these two layers of materials further reduces the heat transfer caused by air heat exchange and solar radiation. A groove 16 is provided inside the circle of the mounting ring 4. This design is used to firmly clamp the glass 7 to ensure the stability and safety of the entire structure. The heat preservation structure of the glass 7 of this excavator realizes the heat management of the internal environment of the cab through the selection of different materials, effectively improves the comfort of the operating environment and reduces energy consumption. The bending angle of the glass 7 is highly matched with the curvature of the installation position of the excavator cab glass 7, which improves the accuracy and sealing of the installation. A number of openings 15 are provided at the four corners of the mounting ring 4. These openings 15 are used to receive the heat-conducting columns 14 fixed to the corresponding parts of the heat-conducting ring 6, so that the heat-conducting columns 14 can smoothly pass through the openings 15, effectively conducting the heat generated inside the glass 7, thereby optimizing the overall heat dissipation performance. In order to achieve effective adjustment of the angle of the air guide plate 12 and ensure that it is fixed to the bottom of the housing 1, cylindrical protrusions are designed at both ends of the air guide plate 12. This structure not only ensures the stability of the air guide plate 12, but also simplifies the operation process, allowing the user to easily adjust the angle of the air guide plate 12 according to actual needs. In order to reduce the temperature exchange between the two sides of the glass 7 plate, a vacuum cavity 9 is designed between the aerogel 8, which significantly reduces the heat conduction between the glass 7 and effectively improves the thermal insulation effect of the entire system. Through these detailed considerations, the performance of the device has been significantly improved, meeting the requirements for efficiency and stability in professional use scenarios. Through sophisticated design and structural innovation, the installation matching, heat dissipation efficiency and thermal insulation functions are improved.

[0030] It is worth noting that the entire device is controlled by a general control device. Since the devices matched with the control device are commonly used devices and belong to existing mature technologies, their electrical connection relationships and specific circuit structures will not be described in detail here.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
