Description

Technical Field

[0001] This utility model relates to the field of DC motor technology, specifically a heat-dissipating dual-gun DC motor. Background Technology

[0002] A dual-gun DC power supply is a device with two DC power outputs that can simultaneously power two devices. It is a common power supply device that uses DC charging technology to charge electric vehicles at higher power, thereby greatly reducing charging time.

[0003] In the prior art, such as the dustproof dual-gun DC charging pile with good heat dissipation performance proposed in patent application number "CN202221316112.4", a cooling component is provided at the bottom of the cabinet, and heat dissipation holes are provided on both sides of the bottom of the cabinet. Heat dissipation mounting frames are fixed inside the two heat dissipation holes. By setting the cooling component and heat dissipation component, the heat inside the chassis can be effectively dissipated, thereby improving the charging efficiency and the service life of the equipment.

[0004] However, the aforementioned patent application uses a single fan for cooling the dual-gun DC charging pile, which is ineffective. The fan also becomes overloaded and heats up after prolonged use, making it difficult to dissipate heat and affecting the cooling of the dual-gun DC charging pile. Furthermore, the dust filter cannot be cleaned properly, and dust will clog the filter after long-term use, which will also affect heat dissipation. Utility Model Content

[0005] The purpose of this invention is to provide a heat-dissipating dual-gun DC motor to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A heat-dissipating dual-gun DC power supply includes a DC power supply body, a base fixedly connected to the bottom surface of the DC power supply body, an outer shell fixedly installed on the upper surface of the base outside the DC power supply body, a circulation pipe fixedly installed on the outer wall of the DC power supply body inside the outer shell, a water tank and a water pump fixedly connected to the outer wall of the base, filters fixedly installed on both outer walls of the outer shell near the bottom, several heat dissipation vents extending through the two outer walls of the DC power supply body near the bottom, exhaust fans fixedly installed on both inner walls of the DC power supply body near the bottom, a cleaning mechanism provided on both outer walls of the outer shell, the cleaning mechanism including two electric telescopic rods and two connecting plates, the two electric telescopic rods and the two connecting plates fixedly installed on the outer walls of the outer shell, connecting wires fixedly connected to both outer walls of the DC power supply body, and a charging gun fixedly connected to one end of each of the two connecting wires.

[0008] Preferably, both exhaust fans are wrapped with cooling pipes, and one end of each cooling pipe is fixedly connected to the other. One end of the circulation pipe is fixedly connected to one of the cooling pipes, and one end of the water pump is fixedly connected to a connecting pipe, which is also fixedly connected to the other cooling pipe.

[0009] Preferably, the end of the water pump away from the second connecting pipe is fixedly connected to the third connecting pipe, and the third connecting pipe is fixedly connected to the water tank. The upper surface of the water tank is fixedly connected to the first connecting pipe, and the end of the first connecting pipe away from the water tank is fixedly connected to the circulation pipe.

[0010] Preferably, a liquid pump is installed inside the water tank, and the output end of the liquid pump is connected to one end of a connecting pipe. A water filling pipe is fixedly connected to the outer wall of the water tank near the upper end.

[0011] Preferably, both of the outer walls of the connecting plates are provided with wavy grooves, and slide rods are inserted into the two wavy grooves. A cleaning roller is fixedly connected between the two slide rods, and a number of bristles are fixedly connected to the outer wall of the cleaning roller.

[0012] Preferably, each of the two electric telescopic rods has a mounting shell fixedly connected to its bottom end, a crossbar fixedly installed inside each of the two mounting shells, a movable block sleeved on the outside of each of the two crossbars, and the movable block is fixedly connected to one end of the sliding rod. A buffer spring is sleeved on the outside of each crossbar near both ends.

[0013] Preferably, a protective shell is fixedly installed on the outer wall of the outer shell and located outside the cleaning roller.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model uses two cooling pipes to exhaust air from the DC motor body, which can accelerate the dissipation of heat inside the DC motor body. At the same time, a liquid pump, in conjunction with a connecting pipe and a circulation pipe, exchanges heat with the outer wall of the DC motor body, which also accelerates heat dissipation. The water flowing through the circulation pipe can simultaneously flow into the two cooling pipes, which can exchange heat with the cooling pipes and dissipate heat, preventing the cooling pipes from overheating and affecting the heat dissipation effect on the DC motor body. Through the above operations, the exhaust fan can not only exhaust air to dissipate heat from the DC motor body, but also perform water cooling heat exchange to dissipate heat from the DC motor body, and can also prevent the exhaust fan from overheating, effectively improving the heat dissipation effect of the DC motor body.

[0016] 2. In this utility model, the mounting shell is moved down by the electric telescopic rod, which in turn moves the cleaning roller installed between the two slide rods down. Together with the bristles on the slide rods, the dust on the filter screen can be cleaned. At the same time, the slide rods move down along the wavy groove. Due to the shape of the wavy groove, the slide rods can move back and forth continuously, which makes the cleaning roller vibrate and clean the filter screen, effectively improving the cleaning effect and preventing the filter screen from clogging and affecting the heat dissipation of the DC motor body.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] A heat-dissipating dual-gun DC motor, such as Figures 1-7 As shown, the device includes a DC motor body 1, a base 14 fixedly connected to the bottom surface of the DC motor body 1, a housing 5 fixedly installed on the upper surface of the base 14 outside the DC motor body 1, a circulation pipe 6 fixedly installed on the outer wall of the DC motor body 1 inside the housing 5, a water tank 9 and a water pump 12 fixedly connected to the outer wall of the base 14, filters 16 fixedly installed on both outer walls of the housing 5 near the bottom, several heat dissipation vents 18 extending through the two outer walls of the DC motor body 1 near the bottom, exhaust fans 7 fixedly installed on both inner walls of the DC motor body 1 near the bottom, a cleaning mechanism provided on both outer walls of the housing 5, the cleaning mechanism including two electric telescopic rods 15 and two connecting plates 17, the two electric telescopic rods 15 and the two connecting plates 17 fixedly installed on the outer walls of the housing 5, connecting wires 2 fixedly connected to both outer walls of the DC motor body 1, and a charging gun 3 fixedly connected to one end of each connecting wire 2.

[0029] Both exhaust fans 7 are wrapped with cooling pipes 8, and one end of the two cooling pipes 8 is fixedly connected to each other. One end of the circulation pipe 6 is fixedly connected to one of the cooling pipes 8. One end of the water pump 12 is fixedly connected to the connecting pipe 2 11, and the connecting pipe 2 11 is fixedly connected to the other cooling pipe 8. The end of the water pump 12 away from the connecting pipe 2 11 is fixedly connected to the connecting pipe 3 13, and the connecting pipe 3 13 is fixedly connected to the water tank 9. The upper surface of the water tank 9 is fixedly connected to the connecting pipe 1 10, and the end of the connecting pipe 1 10 away from the water tank 9 is fixedly connected to the circulation pipe 6. The liquid pump in the water tank 9 pumps water through the connecting pipe 1 10 into the circulation pipe 6 to exchange heat on the outer wall of the DC motor body 1 and accelerate heat dissipation.

[0030] A liquid pump is installed inside the water tank 9, and the output end of the liquid pump is connected to one end of the connecting pipe 10. A water filling pipe is fixedly connected to the outer wall of the water tank 9 near the upper end, and water can be added to the water tank 9 through the water filling pipe.

[0031] In operation, air is expelled from the DC motor body 1 through two cooling pipes 8, accelerating heat dissipation. Simultaneously, water is pumped into the circulation pipe 6 through the connecting pipe 10 from the water tank 9, exchanging heat with the outer wall of the DC motor body 1 and further accelerating heat dissipation. The water flowing through the circulation pipe 6 can simultaneously flow into the two cooling pipes 8, exchanging heat with and dissipating heat from the cooling pipes 8, preventing overheating of the cooling pipes 8 and affecting the heat dissipation effect on the DC motor body 1. Furthermore, in conjunction with the water pump 12 and the connecting pipe 11, the water flowing through the two cooling pipes 8 can be returned to the water tank 9, achieving secondary recycling. Through the above operations, the exhaust fan 7 can both exhaust and dissipate heat from the DC motor body 1, while also providing water-cooled heat exchange, preventing overheating of the exhaust fan 7 and effectively improving the heat dissipation effect on the DC motor body 1.

[0032] Both connecting plates 17 have wavy grooves 22 extending through their outer walls. Slide rods 21 are inserted into the two wavy grooves 22. Cleaning rollers 4 are fixedly connected between the two slide rods 21. Several bristles are fixedly connected to the outer wall of the cleaning rollers 4. Mounting shells 19 are fixedly connected to the bottom ends of the two electric telescopic rods 15. Crossbars 23 are fixedly installed inside the two mounting shells 19. Movable blocks 20 are fitted on the outside of the two crossbars 23, and the movable blocks 20 are fixedly connected to one end of the slide rods 21. Buffer springs are fitted on the outside of the crossbars 23 near both ends. When the slide rods 21 move back and forth, the movable blocks 20 slide back and forth along the crossbars 23 inside the mounting shells 19, and the two buffer springs are continuously compressed accordingly, which can limit the movement position of the slide rods 21.

[0033] A protective shell 24 is fixedly installed on the outer wall of the outer shell 5 and located outside the cleaning roller 4. The protective shell 24 serves to shield and protect the cleaning roller 4, preventing the cleaning roller 4 from being affected by external dust when it is not in use.

[0034] Specifically, the heat of the DC motor body 1 can be dissipated through the various heat dissipation vents 18. The filter screen 16 can block one side of the heat dissipation vent 18 to prevent external dust from entering the heat dissipation vent 18, causing blockage and affecting the heat dissipation effect. The electric telescopic rod 15 drives the mounting shell 19 to move down, which can drive the cleaning roller 4 installed between the two slide rods 21 to move down. With the bristles on the slide rod 21, the dust on the filter screen 16 can be cleaned. At the same time, the slide rod 21 moves down along the wavy groove 22. Due to the shape of the wavy groove 22, the slide rod 21 can move back and forth continuously, which makes the cleaning roller 4 vibrate and clean the filter screen 16, effectively improving the cleaning effect. When the slide rod 21 moves back and forth, the movable block 20 slides back and forth along the crossbar 23 inside the mounting shell 19 with the slide rod 21. The two buffer springs are squeezed accordingly, which can limit the movement position of the slide rod 21.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
