[0022] The present invention is described in detail below in conjunction with specific embodiments and drawings.

[0023] An energy recovery load resistor unit of this embodiment, such as Figure 1 and Figure 2 As shown, it includes an insulating support tube 1, a resistance wire 2 wound around the outside of the support tube 1, a heat dissipation mechanism 3 capable of blowing air into the support tube 1, a light-transmitting tube 4 sleeved outside the support tube 1, and a cylindrical photovoltaic panel 5 sleeved outside the light-transmitting tube 4. The photovoltaic panel 5 is electrically connected to a battery (not shown in the figure). More importantly, the thickness of the resistance wire 2 satisfies that it glows red when it exceeds a preset temperature. In fact, the thickness of the resistance wire 2 can be determined according to the rated voltage. If it is a round iron wire, that is, the wire diameter specification, under the rated voltage, the radial cross-section size of the resistance wire 2 is designed to meet the luminous requirements. For example, under a voltage of 220V, the power-on time for a resistance wire with a wire diameter of x mm to start luminescence is V seconds, and the temperature rise curve with time is obtained by experiment. The photovoltaic panel 5 is used to absorb the light energy of the resistance wire 2 when it is powered on and heated, and convert it into electrical energy to store in the battery, which can be used to power the control circuit in the load box when it is static.

[0024] It should be noted that the photovoltaic panel 5 and the battery are purchased parts, and their internal energy conversion systems are all existing technologies, which will not be described in detail. For photovoltaic light energy absorption charging, this case mainly designs the existing straight photovoltaic panel 5 into a cylindrical shape.

[0025] In this embodiment, the light-transmitting tube 4 is insulated and separated from the resistance wire 2, specifically, a certain gap is reserved to prevent the light-transmitting tube 4 from affecting the temperature of the resistance wire 2 and to prevent the resistance wire 2 from heating up and burning the light-transmitting tube 4. The light-transmitting tube 4 mainly refracts light, allowing the light to be refracted more evenly onto the surface of the photovoltaic panel 5. A gap is left between the light-transmitting tube 4 and the photovoltaic panel 5.

[0026] Since the rated voltage remains unchanged and the load is operating normally, the resistance wire 2 will continue to heat up as the power is on. If it is overheated, the life of the resistance wire 2 and the internal environment temperature of the resistor will be affected. If the temperature is too low and the luminescence is low, the light energy recovery will be affected. Therefore, in this embodiment, the heat dissipation mechanism 3 is connected to a controller to adjust the wind speed gear and then control the temperature of the resistance wire 2, so that the resistance wire 2 can be maintained in a certain temperature range and a certain light intensity range. It not only ensures the normal load of the resistance wire 2, but also guarantees performance safety and light energy recovery.

[0027] In this embodiment, the heat dissipation mechanism 3 is a speed-adjustable fan, which is installed at the end of the support tube 1. In practice, the heat dissipation mechanism 3 can be changed to an air blowing pipe, which is supplied with air by an air pump to blow natural wind to the support tube 1 or add a refrigeration mechanism to blow cold wind. A heat-conducting structure 6 is arranged in the support tube, and the heat-conducting structure 6 includes a base tube 61 made of metal material and a tooth piece 62 arranged circumferentially on the inner wall of the base tube 61. The outer wall of the base tube 61 is attached to the inner wall of the support tube, and the base tube 61 and the tooth piece 62 are an aluminum body cast in one piece. In extreme cases, the heat generated by the resistance wire 2 can be discharged by the heat-conducting structure 6 through the fan without causing the resistance wire 2 to emit light. By adjusting the speed of the fan, the light emission of the resistance wire 2 is adjusted, that is, the energy absorbed by the photovoltaic panel 5 per unit time is adjusted, and the photovoltaic panel 5 is protected from being burned due to overheating. Or when the battery is fully charged and another battery is to be replaced, the speed-adjustable fan can be turned to the maximum, and the energy will not be absorbed by the photovoltaic panel 5.

[0028] In practice, in order to facilitate replacement of the battery after it is fully charged, the battery and the photovoltaic panel 5 are connected via a disassembled joint.

[0029] In this embodiment, the support tube 1 is a porcelain tube, and the light-transmitting tube 4 is a quartz glass tube.

[0030] In this embodiment, the resistance wire 2 is evenly distributed around the outer spiral of the support tube 1, and theoretically, the resistance wire 2 will generate heat evenly. However, in practice, due to various factors, if there is uneven heating, the pitch of the resistance wire 2 is adjusted to adjust the density of the spiral. The pitch is smaller when the heating is less, and the pitch is larger when the heating is greater, so as to achieve the purpose of uniform heating and luminescence.

[0031] In practice, a temperature sensor is provided on the inner or outer side of the support tube to detect the degree of heat and light emission of the resistance wire 2. The temperature sensor is electrically connected to the controller and the heat dissipation mechanism 3, and the heat dissipation degree of the heat dissipation mechanism 3 is controlled according to the temperature signal measured by the temperature sensor.
