However, existing screeds still have some significant problems in their casing design, seriously affecting the overall performance and user experience. Similar potential threats also exist during the operation of the screed.
[0003] The existing leveling machine casing has a relatively simple structure and an unreasonable design. During operation, the leveling machine may generate electric arcs due to electrical faults or mechanical friction, which can easily injure operators. The safety performance urgently needs to be improved, and the heat dissipation performance is also poor. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: an arc-protected screed machine housing structure, comprising: a housing, which is mainly used for the protection of the screed machine, the housing including a reinforcing shell, an insulating shell provided on the outside of the reinforcing shell, and a heat insulation layer provided between the reinforcing shell and the insulating shell;
[0006] The heat dissipation mechanism is mainly used for heat dissipation inside the leveling machine. The heat dissipation mechanism includes an external heat dissipation pipe, one end of which extends into the housing and is equipped with an internal heat dissipation pipe. A fan is provided at the end of the external heat dissipation pipe away from the internal heat dissipation pipe.
[0007] Preferably, both the reinforcing shell and the insulating shell are hollow cavity structures with an opening on one side, wherein the edge of the reinforcing shell is constructed with a stepped sealing boss.
[0008] Preferably, the edge of the insulating shell is provided with a sealing groove adapted to the sealing boss, and the side of the insulating shell is flush with the side of the reinforcing shell.
[0009] Preferably, the inner heat dissipation pipe extends into the housing on one side in an inclined plane, and several crossbars are provided inside the inner heat dissipation pipe.
[0010] Preferably, the crossbars are parallel to each other, and both ends of each crossbar are attached to the inner edge of the internal heat dissipation pipe and form an angle with the fan rotation axis, the angle being between 125° and 160°.
[0011] Preferably, each of the crossbars is provided with a plurality of storage blocks at equal intervals, each storage block is provided perpendicular to the crossbar, and each storage block is filled with phase change material.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model provides an arc-protected screed machine housing structure. The screed machine housing includes a shell and a heat dissipation mechanism. The overall structure is simple and reasonably designed. The shell is mainly used for the protection of the screed machine. The shell includes a reinforcing shell, an insulating shell is provided on the outside of the reinforcing shell, and a heat insulation layer is provided between the reinforcing shell and the insulating shell. The edge of the reinforcing shell is constructed with a stepped sealing boss, and the edge of the insulating shell is provided with a sealing groove adapted to the sealing boss. The stepped edge can improve the sealing performance, and the insulating shell provided on the outside of the reinforcing shell can withstand a certain intensity of arc impact and is not easy to break, thus providing a protective effect and eliminating safety hazards.
[0014] 2. The heat dissipation mechanism of this utility model includes an external heat dissipation pipe, one end of which extends into the housing and is equipped with an internal heat dissipation pipe. A fan is installed at the end of the external heat dissipation pipe away from the internal heat dissipation pipe. Several crossbars are installed inside the internal heat dissipation pipe, and several storage blocks are equally spaced on each crossbar. Each storage block is filled with phase change material. When the equipment generates heat during operation, the phase change material absorbs heat and undergoes a phase change, changing from a solid state to a liquid state, storing a large amount of heat. When the equipment temperature decreases, the phase change material changes from a liquid state to a solid state, releasing heat and achieving efficient heat dissipation. Attached Figure Description
