Technical Field

[0001] This utility model relates to the field of hydraulic power equipment technology, and in particular to a heat insulation and noise reduction module and a hydraulic power station. Background Technology

[0002] Hydraulic power units are mainly used to drive hydraulic tools such as hydraulic submersible pumps, hydraulic breakers, and hydraulic chainsaws in outdoor situations where there is no electricity.

[0003] When a hydraulic power unit is working, the heat radiation from the engine exhaust pipe and the heat generated by its own operation will cause the internal temperature of the hydraulic power unit to rise. Excessive internal temperature will affect the working efficiency of the engine and hydraulic system. In order to reduce heat, the engine's built-in fan draws air from the outside, and the air is drawn into the engine through the deflector to carry away the engine block temperature. However, the internal heat dissipation efficiency of the hydraulic power unit is still low due to heat radiation. At the same time, the engine operation is also accompanied by noise, which in turn affects the performance of the hydraulic power unit. Utility Model Content

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] This utility model embodiment provides a heat insulation and noise reduction module, such as Figures 1 to 3 The device includes a housing 10, a mesh component 30, and an exhaust pipe 20. One end of the housing 10 forms a receiving cavity 102 with an opening 101, and the other end opposite the opening 101 forms an air outlet 103. The mesh component 30 is disposed on the inner wall of the housing 10. The exhaust pipe 20 is disposed in the receiving cavity 102, and one end of the exhaust pipe 20 is connected to the air outlet of the engine (not shown in the figure), and the other end extends to the air outlet 103. Both the mesh component 30 and the housing 10 are made of noise-reducing and heat-insulating materials.

[0025] In application, the housing 10 has an opening 101 at one end for connection with the air guide. The heat generated by the engine itself flows along the opening 101 to the air outlet 103. The exhaust pipe 20 is located in the receiving cavity 102 of the housing 10, with one end connected to the engine's air outlet and the other end extending to the air outlet 103. The gas from the engine exhaust flows along the exhaust pipe 20 to the air outlet 103. The housing 10 and the mesh component 30, made of noise-reducing and heat-insulating materials, can greatly reduce the heat generated by the engine itself and the heat radiation from the engine exhaust pipe 20 to the interior of the hydraulic power station, effectively reducing the temperature inside the hydraulic power station. At the same time, in terms of noise reduction, the noise-reducing and heat-insulating materials have a good absorption and blocking effect on the noise generated by the engine, greatly improving the working environment and reducing noise pollution to the surrounding environment, thus improving the performance of the hydraulic power station.

[0026] The noise reduction and heat insulation material in this embodiment can be glass fiber or rock wool, and no specific limitation is made here.

[0027] As a preferred embodiment, refer to Figure 3 A heat insulation layer 40 is provided between the inner wall of the box 10 and the mesh component 30, and the heat insulation layer 40 is made of heat insulation material.

[0028] The addition of the heat insulation layer 40 further enhances the heat insulation performance of the heat insulation and noise reduction module. The heat insulation material has a low thermal conductivity, effectively preventing heat transfer through the housing 10 and further reducing temperature rise inside the hydraulic power station due to heat radiation. This effectively avoids problems such as component performance degradation and seal aging caused by excessively high temperatures, extending the overall service life of the hydraulic power station. Simultaneously, the reduced temperature further improves engine efficiency, reducing the probability of engine failure due to high temperatures and lowering equipment maintenance costs.

[0029] The thermal insulation material in this embodiment can be ceramic fiber, and no specific limitation is made here.

[0030] As a preferred embodiment, refer to Figures 1 to 3 The housing 10 includes a heat insulation groove 110, an upper heat insulation plate 120, and a side plate 130. Along the length of the heat insulation groove 110, one end of the heat insulation groove 110 forms the opening 101, and the other end is connected to the side plate 130. The air outlet 103 is located on the side plate 130. The upper heat insulation plate 120 is disposed on the top of the heat insulation groove 110 and is detachably connected to the heat insulation groove 110. The inner walls of the heat insulation groove 110 and the upper heat insulation plate 120 are both provided with the mesh element 30.

[0031] The design of this housing 10 offers several advantages. First, the detachable upper heat insulation plate 120 greatly facilitates the installation and maintenance of the heat insulation and noise reduction module, improving work efficiency. Second, the inner walls of both the heat insulation groove 110 and the upper heat insulation plate 120 are equipped with mesh components 30, forming a comprehensive heat insulation and noise reduction protection system, further enhancing the performance of the heat insulation and noise reduction module.

[0032] As a preferred embodiment, refer to Figure 1 and Figure 4 The mesh component 30 includes a connecting frame 310 and a mesh plate 320 disposed on one side of the connecting frame 310. One end of the connecting frame 310 away from the mesh plate 320 is connected to the heat insulation groove 110 or the upper heat insulation plate 120, and forms a receiving space 301 with the inner wall of the heat insulation groove 110 and the inner wall of the upper heat insulation plate 120. The heat insulation layer 40 is disposed in the receiving space 301.

[0033] The space 301 formed by the connecting frame 310, the heat insulation groove 110, and the upper heat insulation plate 120 provides a stable installation position for the heat insulation layer 40, preventing the heat insulation layer 40 from shifting or falling off due to vibration or other factors during equipment operation, and ensuring that the heat insulation performance of the heat insulation layer 40 can continuously and stably play its role in heat insulation and noise reduction.

[0034] The presence of the perforated plate 320 effectively absorbs noise while ensuring that gas passes through the perforated plate 320 to reach the heat insulation tank 110 and the upper heat insulation plate 120, so as to fully achieve the purpose of heat insulation and noise reduction through the heat insulation tank 110 and the upper heat insulation plate 120.

[0035] Figure 4 The diagram shows the structure of the upper heat insulation plate 120 and the perforated plate 320. The diagram shows the structure of the heat insulation groove 110 and the perforated plate 320. The upper heat insulation plate 120 and the perforated plate 320 are the same. Further demonstration and explanation are not provided here.

[0036] As a preferred embodiment, refer to Figure 1 and Figure 3 The heat insulation tank 110 has a snap-fit ​​groove 1101 at one end away from the side plate 130. The opening 101 is located in the snap-fit ​​groove 1101. The snap-fit ​​groove 1101 is used to snap with the flow guide. The bottom wall of the snap-fit ​​groove 1101 is connected to the flow guide (not shown in the figure) by a first fastener (not shown in the figure). A connector 111 is provided at one end of the outer wall of the heat insulation tank 110 near the upper heat insulation plate 120. The connector 111 is located in the hydraulic power station by a second fastener (not shown in the figure).

[0037] The snap-fit ​​groove 1101 and the guide shield, along with the use of the first fastener, ensure a reliable sealed connection between the heat insulation tank 110 and the guide shield. During the operation of the hydraulic power station, this effectively prevents heat and noise generated by the engine from diffusing outwards from the heat insulation and noise reduction module, further improving its performance. Secondly, the heat insulation tank 110 is connected to the hydraulic power station via the connector 111 and the second fastener, ensuring the stability of the entire heat insulation and noise reduction module during equipment operation. Even under complex operating conditions such as vibration and impact, the heat insulation and noise reduction module will not loosen or shift, ensuring its long-term stable heat insulation and noise reduction function and improving the reliability and safety of the equipment.

[0038] As a preferred embodiment, refer to Figure 1 and Figure 2 The top of the heat insulation groove 110 has a rectangular structure, and four connectors 111 are provided, which are distributed on the opposite side walls of the heat insulation groove 110 along the width direction of the heat insulation groove 110.

[0039] The design of the connector 111 ensures a more secure and stable installation of the heat insulation and noise reduction module within the hydraulic power station. This design also facilitates installation and disassembly, allowing operators to easily install the heat insulation and noise reduction module into its designated location within the hydraulic power station. Furthermore, it enables quick disassembly for maintenance or module replacement, thus improving work efficiency.

[0040] As a preferred embodiment, refer to Figure 1 and Figure 3 The bottom of the heat insulation groove 110 is also provided with a first clearance groove 1102 along the length direction, and the bottom of the heat insulation groove 110 is also provided with a second clearance groove 1103 at the end near the air outlet 103.

[0041] The first clearance groove 1102 and the second clearance groove 1103 provide sufficient installation and layout space for other components inside the hydraulic power station, avoiding interference with the heat insulation and noise reduction module. This ensures the normal installation and connection of each component, and also makes the internal spatial layout of the hydraulic power station more compact and reasonable, improving the integration of the equipment.

[0042] As a preferred embodiment, refer to Figure 1 The air outlet 103 is provided in several places and is evenly distributed in an array on the side plate 130.

[0043] From a heat dissipation perspective, the multiple evenly distributed air outlets 103 enable the hot air inside the housing 10 to be discharged more quickly and evenly, significantly improving heat dissipation efficiency, accelerating heat dissipation, and further reducing the temperature inside the hydraulic power station. In terms of noise reduction, the evenly distributed air outlets 103 ensure smoother airflow during gas discharge, reducing the noise intensity and further enhancing the noise reduction effect of the heat insulation and noise reduction module.

[0044] As a preferred embodiment, the exhaust pipe 20 is a muffler.

[0045] Among these factors, the noise generated during engine exhaust is one of the main sources of noise in the hydraulic power unit. The exhaust pipe 20 is a muffler, and its internal structure typically employs special designs, such as sound-absorbing material filling and muffler chamber setup, to effectively reduce the noise generated during engine exhaust and further enhance the noise reduction performance of the heat insulation and noise reduction module. The muffler in this embodiment can utilize an existing structure, which will not be described in detail here.

[0046] This application also discloses a hydraulic power station, including the heat insulation and noise reduction module in the foregoing embodiments. This hydraulic power station has the same structure and beneficial effects as the heat insulation and noise reduction module in the foregoing embodiments. The structure and beneficial effects of the heat insulation and noise reduction module have been described in detail in the foregoing embodiments and will not be repeated here.
