Description

Technical Field

[0001] The utility model relates to the field of energy management, in particular to an energy management device. Background Art

[0002] Wind power generation is the process of converting the kinetic energy of wind into electrical energy, converting the kinetic energy of wind into mechanical kinetic energy, and then converting mechanical energy into electrical kinetic energy. This is wind power generation. The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then increase the speed of rotation through a speed increaser to drive the generator to generate electricity. According to current windmill technology, it can start generating electricity at a breeze speed of about three meters per second. Wind power generation is becoming a trend in the world because wind power generation does not require the use of fuel and does not produce radiation or air pollution:

[0003] The device required for wind power generation is called a wind energy storage unit. The cables of the wind energy storage unit are generally installed using plastic clips. However, when the cables are subjected to external force, the clips are prone to breakage, causing the cables to fall off.

[0004] Under the prior art, a Chinese patent with application number "202122882433.2" discloses a cable fixing device for energy storage grid-connected wind power generation equipment, including an I-shaped bottom plate component and a plurality of cable bodies placed above one side of the I-shaped bottom plate component and a plurality of inverted L-vertical plate components for fixing the cable bodies. An arc-shaped pressing plate for pressing down the cable body is provided below the L-vertical plate component. The arc-shaped pressing plate can apply downward pressure to the cable body, press down and clamp the cable body, and the arc-shaped pressing plate is connected to the L-vertical plate component through an elastic pressing clamping component. A pressing clamp is provided at the bottom of the L-vertical plate component. Four threaded countersunk holes are provided on the top surface of the I-shaped bottom plate component, and a plurality of L-vertical plate components are slidably connected to the top surface of the I-shaped bottom plate component. The cable fixing device for energy storage grid-connected wind power generation equipment can not only press down and clamp the cable body, but also has the function of clamping, thereby improving the stability of the cable body and preventing the cable body from falling off.

[0005] The above patent can stabilize the energy cables to a certain extent and prevent the cables from being damaged. However, in actual operation, the wind power storage unit is built outdoors, and the fixed cables are also exposed to the air. The cables are still likely to be damaged and are prone to aging. Therefore, we propose an energy management device to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example: Figure 1-Figure 5 As shown, the utility model provides an energy management device, including an energy storage unit 1, a power cable 3 is arranged on one side of the energy storage unit 1, a connector 301 is fixedly connected to the end of the power cable 3, a winding assembly 2 for preparing the power cable 3 is arranged in the inner cavity of the energy storage unit 1, and an operation panel 101 is arranged on one side of the energy storage unit 1, and the operation of the energy storage unit 1 is controlled by the operation panel 101.

[0026] In order to facilitate the preparation of the power cable 3, an assembly box 201 is provided in the winding component 2, and the assembly box 201 is arranged on one side inside the energy storage unit 1. A connecting window 202 is provided on one side of the assembly box 201 for easy protrusion of the power cable 3, and the connector 301 is snap-fitted with the connecting window 202. A support tube 203 is fixedly connected to the bottom of the inner cavity of the assembly box 201, and limiting windows 204 that penetrate the support tube 203 are provided on both sides of the support tube 203. The limiting windows 204 on both sides are symmetrically distributed along the axis of the support tube 203. A telescopic spring 205 is built into the support tube 203, and one end of the telescopic spring 205 is in contact with the bottom of the inner cavity of the support tube 203. A support rod 206 is provided at the other end of the telescopic spring 205. The support rod 206 is placed in the support tube 203 and is slidably connected thereto. The support rod 206 is fixedly connected to the limiting position on both sides close to the limiting windows 204. The seat 207, one end of the limit seat 207 away from the support rod 206 extends from the limit window 204 to the outside, the limit seat 207 is slidably connected to the inner wall of the limit window 204, and the top of the support rod 206 is fixedly connected with a mounting tube 208, and the mounting tube 208 coincides with the axis of the support tube 203. By pressing the pressure plate, the winding roller 210 and the rotating wheel 212 are driven away from the connecting seat 215, and the winding roller 210 and the bottom support rod 206 will squeeze the bottom telescopic spring 205. At the same time, as the rotating wheel 212 moves, the teeth 216 of the connecting seat 215 will disengage from the multiple tooth grooves 213 of the rotating wheel 212, because the upper end surface of the tooth groove 213 has an opening and is provided with an inclined surface 214. At this moment, the winding roller 210 is no longer fixed, and the winding roller 210 can squeeze the telescopic spring 205 to move downward, which is convenient for its own fixing and loosening.

[0027] In order to allow the device to prepare the power cable 3 by itself, a winding roller 210 is rotatably connected to the bottom of the inner cavity of the mounting cylinder 208, and a coil spring 209 is sleeved on the surface of one end of the winding roller 210 in the mounting cylinder 208. The coil spring 209 is placed in the mounting cylinder 208, and one end of the coil spring 209 is fixedly connected to the winding roller 210, and the other end of the coil spring 209 is fixedly connected to the inner wall of the mounting cylinder 208. Two limiting plates 211 are sleeved on one end of the winding roller 210 outside the mounting cylinder 208, and the power cable 3 is wound around the surface of the winding roller 210, and the power cable 3 is arranged between the two limiting plates 211. A rotating wheel 212 is sleeved on the surface of the end of the winding roller 210 away from the mounting cylinder 208, and the rotating wheel 212 is fixedly connected to the winding roller 210, and a plurality of tooth grooves 213 are provided around the rotating wheel 212. The teeth 213 are evenly distributed around the axis of the rotating wheel 212, and inclined surfaces 214 are provided on both sides of the top of the teeth 213. The rotating wheel 212 does not contact the inner wall of the assembly box 201. A plurality of connecting seats 215 are fixedly connected around the inner wall of the assembly box 201. The connecting seat 215 is fixedly connected with teeth 216 matching the teeth 213 on one side close to the axis of the assembly box 201. The rotating wheel 212 is meshedly connected with the connecting seat 215, and the end of the winding roller 210 away from the mounting cylinder 208 passes through the assembly box 201 and extends to the outside of the energy storage unit 1. If the power cable 3 needs to be prepared, the pressure plate can be directly pressed, and the rotating wheel 212 is disengaged from the connecting seat 215. The winding roller 210 rotates automatically under the elastic drive of the bottom coil spring, and the external power cable 3 can be wound up for easy use.

[0028] Working principle: When using this device, if a longer power cable 3 is needed, the pressure plate can be pressed to drive the winding roller 210 and the rotating wheel 212 away from the connecting seat 215, and the winding roller 210 and the bottom support rod 206 will squeeze the bottom telescopic spring 205. At the same time, as the rotating wheel 212 moves, the teeth 216 of the connecting seat 215 will be separated from the multiple tooth grooves 213 of the rotating wheel 212. Because the upper end surface of the tooth groove 213 has an opening and is provided with an inclined surface 214, the winding roller 210 is no longer fixed at this moment, which is convenient for the user to pull out the winding roller 210. The power cable 3 of the required length can be used. After being pulled out to a certain length, the pressure plate can be loosened so that the winding roller 210 can rebound by itself under the elastic force of the telescopic spring 205, and the rotating wheel 212 and the connecting seat 215 can be fixed again to prevent the winding roller 210 from rotating. If the power cable 3 needs to be prepared, the pressure plate can be directly pressed to disengage the rotating wheel 212 from the connecting seat 215. The winding roller 210 can rotate by itself under the elastic drive of multiple winding springs fixed at the bottom, and the external power cable 3 can be rolled up. The organizing effect is good and it is easy to use.
