A bearing is arranged inside the rotating nut to ensure that the connecting end can be tightly connected to the device. The insulating plate is an insulating structure made of a polymer insulating material to prevent the danger caused by leakage. The filter capacitor is connected in parallel at the output end of the rectifier power supply circuit to make the working performance of the electronic circuit more stable.

[0018] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0019] The first embodiment of the present application is:

[0020] See also Figures 1 to 3 ,in, Figure 1 This is a schematic diagram of the overall structure of a heat dissipation structure of an elevator energy feedback device according to the first embodiment of the utility model. Figure 2 is a schematic structural diagram of a heat dissipation assembly according to a first embodiment of the utility model. Figure 3 It is a structural schematic diagram of the circulation component of the first embodiment of the utility model. The utility model provides a heat dissipation structure of an elevator energy feedback device, including a feedback box 101, a heat dissipation component, a circulation component and a connecting component. The heat dissipation component includes a fixed frame 102 and an M-shaped heat dissipation plate 103, and the circulation component includes a guide pump 104, a guide pipe 105, a shunt pipe 106, a heat dissipation pipe 107, a return pipe 108 and a circulation pipe 109. The connecting component includes a connecting seat 110 and a connecting bolt 111; the above-mentioned scheme solves the problem that the elevator energy feedback device only dissipates heat through a heat dissipation plate, and when the equipment is in high-load continuous operation, it is easy to make the internal temperature of the device too high, resulting in damage to the electronic components inside the device. It can be understood that the above-mentioned scheme can be used in the scenario of dissipating heat from the energy feedback device during elevator energy recovery, and can also be used to solve the installation problem of the energy feedback device.

[0021] According to the present specific embodiment, there are two fixing frames 102, which are fixedly connected to the feedback box 101 and located at both sides of the feedback box 101, and there are two M-shaped heat sinks 103, which are fixedly connected to the fixing frames 102 and located between the fixing frames 102 and the feedback box 101, respectively. The circulation component and the connecting component are connected to the feedback box 101, respectively, and the buffer component is connected to the connecting component. The fixing frame 102 is used to provide support and fixation for the M-shaped heat sink 103. The M-shaped heat sink 103 is a heat sink composed of a plurality of M-shaped structures. The M-shaped heat sinks 103 on both sides increase the contact area between the feedback box 101 and the external flowing air, thereby increasing the heat dissipation efficiency of the device. The circulating coolant in the circulation component is used to further dissipate heat for the feedback box 101.

[0022] There are two diversion pumps 104, which are fixedly connected to the feedback tank 101 and located at the outside of the feedback tank 101. There are two diversion pipes 105, which are fixedly connected to the diversion pumps 104 and located at the bottom of the diversion pipes 105. There are two diversion pipes 106, which are fixedly connected to the diversion pipes 105 and pass through the feedback tank 101. The diversion pump 104 provides power for circulating water. The circulating cooling water is pumped into the diversion pipe 105 through the diversion pump 104. The cooling water is pumped into the diversion pipe 106 for diversion through the diversion pipe 105, so that the cooling water flows into each of the heat dissipation pipes 107 between the M-shaped heat sink 103 and the feedback tank 101, so as to further dissipate the heat of the feedback tank 101.

[0023] Secondly, there are multiple heat dissipation pipes 107, which are fixedly connected to the shunt pipe 106 and located at the top of the shunt pipe 106 respectively. There are two return pipes 108, which are fixedly connected to the heat dissipation pipe 107 and pass through the feedback box 101 respectively. There are two circulation pipes 109, which are fixedly connected to the return pipe 108 and located at the top of the diversion pump 104 respectively. The cooling water diverted by the shunt pipe 106 enters the heat dissipation pipe 107, and the feedback box 101 is further cooled by the multiple heat dissipation pipes 107. The circulating water flows back to the diversion pump 104 again through the return pipe 108 and the circulation pipe 109, so as to achieve the purpose of recycling the cooling water.

[0024] Again, there are multiple connecting seats 110, which are fixedly connected to the feedback box 101 and located on both sides of the feedback box 101. There are multiple connecting bolts 111, which are slidably connected to the connecting seats 110 and pass through the connecting seats 110. The connecting seats 110 provide support for the device, and the connecting seats 110 and the feedback box 101 are fixed by the connecting bolts 111.

[0025] A heat dissipation structure of an elevator energy feedback device is used in the present embodiment. The fixing frame 102 is used to provide support and fixation for the M-shaped heat sink 103. The M-shaped heat sink 103 is a heat sink composed of multiple M-shaped structures. The contact area between the feedback box 101 and the external flowing air is increased by the M-shaped heat sinks 103 on both sides, thereby increasing the heat dissipation efficiency of the device. The circulating coolant in the circulation component is used to further dissipate the heat of the feedback box 101, thereby solving the problem that the elevator energy feedback device only dissipates heat through one heat sink, which easily causes the internal temperature of the device to be too high when the device is in high-load continuous operation, thereby causing damage to the electronic components inside the device.

[0026] The second embodiment of the present application is:

[0027] Based on the first embodiment, please refer to Figure 4 ,in, Figure 4 It is a structural schematic diagram of a connecting component and a buffer component of the second embodiment of the utility model.

[0028] The heat dissipation structure of the elevator energy feedback device of this embodiment further includes a buffer component, and the buffer component includes a buffer rod 201 , a buffer pad 202 and a buffer spring 203 .

[0029] According to the present specific embodiment, there are multiple buffer rods 201, and the multiple buffer rods 201 are respectively slidably connected to the connecting seat 110 and respectively pass through the connecting seat 110. There are multiple buffer pads 202, and the multiple buffer pads 202 are respectively fixedly connected to the buffer rods 201. A buffer spring 203 is fixedly connected to the outer side of each buffer rod 201. The buffer rod 201 provides support for the buffer pad 202. The buffer pad 202 is in contact with the external connection position. The elastic force provided by the buffer spring 203 makes the buffer pad 202 have a certain amount of collapse, thereby preventing the feedback box 101 from shaking violently and causing damage to the device in the feedback box 101.

[0030] Using the heat dissipation structure of an elevator energy feedback device of this embodiment, the elastic force provided by the buffer spring 203 allows the buffer pad 202 to have a certain amount of collapse, thereby preventing the feedback box 101 from shaking violently and causing damage to the device in the feedback box 101.
