Technical Field
[0001] This utility model relates to the field of snowplow technology, specifically to a high-power motor with variable speed adjustment for snowplows. Background Technology
[0002] Snow sweepers are an important piece of equipment for snow removal in winter. They have significant advantages such as high efficiency, economy, and environmental protection. With the increasing economic strength and continuous social progress, snow removal equipment is being promoted and used both domestically and internationally. Snow sweepers are easy to operate, have high work efficiency, and one snow sweeper is equivalent to the labor of 20 people. They have excellent snow throwing distance and the snow throwing direction can be set individually. Currently, the power system of snow sweepers mostly uses a single-speed motor with a fixed speed or achieves limited speed regulation through a mechanical gearbox.
[0003] With the increasing demands for urban snow removal efficiency, the demand for high-power snow removal equipment has grown significantly. However, as the power of traditional motors increases, the heat generated during use also increases. Existing motors mostly rely on fans at the shaft end for heat dissipation, which has low heat dissipation efficiency.
[0004] Therefore, it is necessary to invent a high-power motor with variable speed regulation for snow sweepers to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a high-power motor with variable speed adjustment for snow sweepers, in order to solve the problem of low heat dissipation efficiency in the technology.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-power motor with variable speed adjustment for a snow sweeper, comprising a waterproof housing and a motor body, wherein the motor body is fixedly installed inside the waterproof housing, an axial fan is installed at the rear end of the motor body, and a heat dissipation assembly is provided on the surface of the waterproof housing, the heat dissipation assembly comprising heat dissipation holes, a fixing plate, a liquid storage box, heat dissipation fins, heat exchange pipes and a bladeless fan.
[0007] By adopting the above technical solution, the waterproof casing protects the motor body and prevents snow water from splashing onto the surface of the motor body. At the same time, the axial fan and heat dissipation components dissipate heat from the motor body, effectively improving the heat dissipation effect.
[0008] Optionally, a rear end plate is fixedly connected to the rear end of the motor body, the heat dissipation hole is opened on the surface of the rear end plate, and a dustproof mesh is fixedly connected inside the heat dissipation hole.

[0010] Optionally, the heat exchange pipe is wound around the surface of the waterproof housing, and multiple sets of longitudinal heat dissipation fins are fixedly connected to the surface of the heat exchange pipe.

[0012] Optionally, one inner end of each of the multiple sets of heat dissipation fins is fixedly connected to the surface of the waterproof housing, and one inner end of the heat dissipation fin penetrates the waterproof housing and abuts against the surface of the motor body.
[0013] By adopting the above technical solution, multiple sets of heat dissipation fins facilitate the rapid transfer of heat generated by the motor to the outside.
[0014] Optionally, the fixing plate is fixedly connected to the upper side of the rear end of the waterproof shell, and the liquid storage box is fixedly installed on the upper surface of the fixing plate.

[0017] By adopting the above technical solution, coolant is injected into the inside of the reservoir through the injection hole. Then, the coolant enters the heat exchange pipe through the reservoir to exchange heat with the heat dissipation fins, thereby quickly cooling the motor body.
[0018] Optionally, the bladeless fan is fixed to the surface of the waterproof housing near the front end.
[0019] By adopting the above technical solution, the bladeless fan blows airflow onto the heat dissipation fins, increasing the airflow speed on the surface of the heat dissipation fins and further improving the heat dissipation effect of the motor body.
[0020] Optionally, a front sealing plate is fixedly connected to the front end of the waterproof housing, and a mounting base is fixedly connected to the lower side of the rear end of the waterproof housing. The surface of the mounting base has multiple sets of mounting holes.
[0021] By adopting the above technical solution, the front sealing plate seals the front end of the waterproof shell, further improving the waterproof effect. The mounting base and mounting hole cooperate to facilitate the installation and fixing of the waterproof shell and the motor body.
[0022] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0023] This invention uses an axial fan in conjunction with heat dissipation holes to cool the motor body. At the same time, multiple sets of heat dissipation fins quickly conduct heat exchange between the coolant inside the heat exchange pipe and the heat dissipation fins. The bladeless fan quickly dissipates the dissipated heat, further improving the heat dissipation effect of the motor body. This allows the motor body to operate for a longer period of time, effectively increasing the working time of the snow sweeper and improving snow sweeping efficiency. Attached Figure Description

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0032] This utility model provides, for example Figures 1 to 5 The high-power variable-speed motor for a snowplow shown includes a waterproof housing 1 and a motor body 3. The motor body 3 is fixedly installed inside the waterproof housing 1. An axial fan 31 is installed at the rear end of the motor body 3. A front sealing plate 11 is fixedly connected to the front end of the waterproof housing 1. A mounting base 14 is fixedly connected to the lower side of the rear end of the waterproof housing 1. Multiple sets of mounting holes 15 are opened on the surface of the mounting base 14. A rear sealing plate 12 is fixedly connected to the rear end of the motor body 3. Heat dissipation holes 13 are opened on the surface of the rear sealing plate 12. A dustproof net is fixedly connected inside the heat dissipation holes 13. A heat dissipation assembly is provided on the surface of the waterproof housing 1. The heat dissipation assembly includes heat dissipation holes 13, a fixing plate 16, a liquid storage box 17, heat dissipation fins 19, heat exchange pipes 110, and a bladeless fan 2.
[0033] The motor body 3 is a high-power motor with variable speed adjustment. It is fixedly installed inside the waterproof housing 1, and the front end of the waterproof housing 1 is sealed by the front sealing plate 11 and the rear end of the waterproof housing 1 is sealed by the rear sealing plate 12, which effectively improves the waterproof effect of the motor body 3 and avoids snow water from affecting its operation.
[0034] In addition, during the operation of the motor body 3, the axial fan 31 will rotate. The axial fan 31 works with the heat dissipation hole 13 to dissipate heat from the motor body 3. At the same time, the heat dissipation component further improves the heat dissipation effect of the motor body 3. The dustproof net on the surface of the heat dissipation hole 13 blocks external snow blocks, preventing snow blocks and dust from entering the interior of the waterproof shell 1, further improving the protective effect of the waterproof shell 1.
[0035] See Figures 2 to 4 The heat exchange pipe 110 is wrapped around the surface of the waterproof housing 1. Multiple sets of longitudinal heat dissipation fins 19 are fixedly connected to the surface of the heat exchange pipe 110. One end of each set of heat dissipation fins 19 is fixedly connected to the surface of the waterproof housing 1. One end of each heat dissipation fin 19 penetrates the waterproof housing 1 and abuts against the surface of the motor body 3. The fixing plate 16 is fixedly connected to the upper part of the rear end of the waterproof housing 1. The liquid storage box 17 is fixedly installed on the upper surface of the fixing plate 16. Both ends of the heat exchange pipe 110 are fixedly connected to the surface of the liquid storage box 17. The upper end of the liquid storage box 17 is provided with a liquid injection hole 18. The bladeless fan 2 is fixed on the surface of the waterproof housing 1 near the front end.
[0036] Specifically, during the process of the heat dissipation component cooling the motor body 3, the bladeless fan 2 is first started. During the operation of the motor body 3, the heat generated by the motor body 3 is quickly dissipated to the outside through multiple sets of heat dissipation fins 19. At this time, the coolant inside the heat exchange pipe 110 exchanges heat with the heat dissipation fins 19 to cool the motor body 3. At the same time, the bladeless fan 2 accelerates the airflow speed on the surface of the heat dissipation fins 19, so that the external cold air passes quickly between the multiple sets of heat dissipation fins 19, and quickly removes the heat from their surface, further improving the heat dissipation effect of the motor body 3.
[0037] The working principle of this utility model is as follows: the axial fan 31, together with the heat dissipation holes 13, dissipates heat from the motor body 3. At the same time, multiple sets of heat dissipation fins 19 quickly conduct heat out of the waterproof shell 1. At this time, the coolant inside the heat exchange pipe 110 and the heat dissipation fins 19 exchange heat. The bladeless fan 2 quickly blows away the conducted heat, further improving the heat dissipation effect of the motor body 3, enabling the motor body 3 to operate for a long time, effectively increasing the working time of the snow sweeper and improving snow sweeping efficiency.
