Description

Technical Field

[0001] The utility model relates to the technical field of power supply for construction site pile drivers, in particular to a high-power discharge machine series connection device dedicated to power supply for construction site pile drivers. Background Art

[0002] A construction project refers to an engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. Pile drivers are often needed in construction projects. Pile drivers are pile-driving machines that use impact force to penetrate piles into the ground.

[0003] During use, the pile driver needs to be powered by a discharger series device. In the prior art, most of the discharger series devices on the market are provided with a shell and a plurality of batteries located inside the shell and connected in series. However, most of the discharger series devices on the market only have heat dissipation holes on the surface of the shell to dissipate heat. When the device is used for a long time or in summer, a large amount of heat will be generated. The heat dissipation of the batteries cannot be timely dissipated by simply opening the heat dissipation holes. Poor heat dissipation will affect the normal operation of the batteries, and the batteries may explode due to heat accumulation. In view of this, we propose a high-power discharger series device specially used for powering pile drivers on construction sites. Utility Model Content

[0031] The heat dissipation mechanism 7 is arranged inside the box body 1 and is used to diffuse the heat generated by the plurality of battery bodies 5 and the plurality of semiconductor refrigerators 6 during operation to the outside of the box body 1.

A roller 74 located inside the box body 1 and rotatably connected to several fixed rods 72 on the same side is coaxially fixed on the surface. A fan blade 75 located inside the box body 1 and used to diffuse heat is fixed on the rear surface of the roller 74. Several battery bodies 5 are connected in series so that high-power power can be supplied to the construction site pile driver. By arranging a heat spreader 4 and several semiconductor refrigerators 6, the heat of several battery bodies 5 during operation can be dissipated. The heat generated by several semiconductor refrigerators 6 and several battery bodies 5 during operation can be diffused to the outside of the box body 1 through the heat dissipation mechanism 7, so that the heat of several battery bodies 5 can be dissipated in time, preventing several battery bodies 5 from being affected in their normal operation due to poor heat dissipation when used for a long time or in summer, and preventing several battery bodies 5 from exploding due to heat accumulation.

[0032] In this embodiment, the heat dissipation mechanism 7 also includes a rotating shaft 711 coaxially connected to the output shaft of the motor 710, two driving gears 79 located inside the installation box 3 and meshing with each other, and a rotating rod 78 coaxially fixed on the front surface of the connecting column 76 and rotatably connected to the front inner wall of the installation box 3.

[0034] Furthermore, a plurality of guide grooves are provided on the top surface of the box body 1, and a plurality of guide blocks 10 are fixed at the bottom end of the box cover 2 and are slidably plugged into the guide grooves on the same side of the top surface of the box body 1, so as to guide the assembly and disassembly of the box cover 2.

In this article, the distance between the motor 710 and the rotating rod 78 is preferably 10cm, and the distance between the motor 710 and the driving gear 79 on the same side is preferably 8cm, so that the connecting column 76, the active heat dissipation gear 77, the two rotating columns 71, the two driven heat dissipation gears 73, the rotating rod 78, the two driving gears 79, the motor 710 and the rotating shaft 711 can operate normally.

[0038] It is worth emphasizing that the transverse cross-sectional shape of the guide groove on the top surface of the box body 1 is I-shaped, and the shape of the guide block 10 is I-shaped which is compatible with the shape of the guide groove on the top surface of the box body 1, which can make the connection between the guide block 10 and the guide groove on the same side of the top surface of the box body 1 tighter, and thus indirectly make the connection between the box cover 2 and the box body 1 tighter.

The specific connection means should refer to the working principle of the utility model. The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection means are all well-known technologies in the field.

[0040] In the specific use of this embodiment, when it is necessary to dissipate heat for several battery bodies 5 in the working process, firstly, several semiconductor refrigerators 6 and motors 710 are started by the external PLC, and after the several semiconductor refrigerators 6 are started, the temperature of the heat spreader 4 can be reduced. After the temperature of the heat spreader 4 is reduced, heat exchange can be performed with the several battery bodies 5, and then the heat dissipation treatment of the several battery bodies 5 can be performed;

[0041] At the same time, the output shaft of the motor 710 rotates to drive the rotating shaft 711 coaxially connected thereto to rotate, and the rotating shaft 711 rotates to drive the driving gear 79 coaxially fixed thereto on the same side to rotate, and the driving gear 79 rotates to drive another driving gear 79 meshing therewith to rotate, and the other driving gear 79 rotates to drive the rotating rod 78 coaxially fixed thereto to rotate, and the rotating rod 78 rotates to drive the connecting column 76 coaxially fixed thereto to rotate, and the connecting column 76 rotates to drive the active heat dissipation gear 77 coaxially fixed thereto to rotate, and the active heat dissipation gear 77 rotates to drive the two driven heat dissipation gears 73 meshing therewith to rotate, and the driven heat dissipation gear 73 rotates to drive the rotating column 71 coaxially fixed thereto to rotate, and the rotating column 71 rotates to drive the rotating roller 74 coaxially fixed thereto on the same side to rotate, and the rotating roller 74 rotates to drive the fan blade 75 fixed thereto to rotate, and the fan blade 75 rotates so that the heat generated by the plurality of battery bodies 5 and the plurality of semiconductor refrigerators 6 during operation can be dissipated through the two heat dissipation holes on the rear surface of the box body 1, and ventilation can also be carried out through the two vents on the left and right side surfaces of the box body 1 while dissipating heat.
