[0015] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of protection of this utility model.

[0016] Please see Figure 1 , Figure 2 A solar-powered laser level gauge includes a laser rangefinder 10 and a rangefinder rod 20 axially mounted to the bottom of the laser rangefinder 10. The laser rangefinder 10 has a laser rangefinder sensor (not shown) at the bottom that emits a laser beam into the rangefinder rod 20, a lithium battery (not shown) that powers the laser rangefinder sensor installed inside, and a solar panel 11 that charges the lithium battery embedded at the top. The laser rangefinder 10 has a trigger switch 12 at one end for controlling the laser rangefinder sensor and a charging port 13 at the other end for externally charging the lithium battery.

[0017] The ranging probe 20 has a hollow cavity inside. The ranging probe 20 has a rod section 21 and a tapered foot section 22 located below the rod section 21. The rod section 21 has scale lines 201 along the axial direction and several through holes 202 at intervals that communicate with the hollow cavity. The rod section 21 has a float ball inside the hollow cavity that can float with the liquid surface, which is used to cooperate with the laser ranging sensor to measure the distance to the liquid surface.

[0018] Furthermore, in this embodiment, the bottom of the laser rangefinder 10 extends downward to form a connecting cylinder 101, and the top of the rod section 21 extends upward to form a connecting edge 203 that can penetrate into the connecting cylinder 101. The inner wall of the connecting cylinder 101 and the outer wall of the connecting edge 203 are provided with matching threads for screwing the laser rangefinder 10 and the rangefinder rod 20 together.

[0019] Furthermore, in this embodiment, the upper part of the rod section 21 is a scale area 211, and the lower part is a positioning area 212. The scale line 201 is set on the scale area 211, and the float is located in the hollow cavity of the scale area 211. A positioning disk 30 is detachably installed on the positioning area 212, and the top of the positioning disk 30 is flush with the 0 position of the scale line 201.

[0020] Furthermore, in this embodiment, the laser rangefinder 10 has a recessed waterproof groove 102 at the location of the charging port 13 and a waterproof cover 103 that can be opened and closed relative to the waterproof groove 102. When the waterproof cover 103 covers the waterproof groove 102, it seals the charging port 13 and achieves a waterproof effect.

[0021] Furthermore, in this embodiment, the waterproof groove 102 is provided with a power switch 14 that controls the power supply of the lithium battery to the laser rangefinder sensor. When the waterproof cover 103 covers the waterproof groove 102, the power switch 14 is sealed together to achieve a waterproof effect.

[0023] Understandably, the method of using a solar-powered laser level gauge according to this utility model includes the following steps: First, the laser level gauge is inserted into the area to be measured with its conical foot section 22, and the positioning plate 30 abuts against the bottom surface of the area to be measured, axially positioning the laser level gauge in the area to be measured. Liquid flows into the hollow cavity through the through hole 202, causing the float to rise with the liquid surface. Second, the laser ranging head 10 is activated, and the laser ranging sensor emits a laser beam into the ranging rod 20. The float reflects the laser beam back to the laser ranging sensor, and the distance from the liquid surface to the bottom surface is calculated by the laser ranging sensor from the time of emission to reception. During this operation, the lithium battery powers the laser ranging sensor, while the solar panel 11 charges the lithium battery, providing sufficient support for the laser level gauge's continuous operation.

[0024] In summary, the laser level gauge powered by solar energy of this invention has a compact and simple overall structure through the cooperation between the laser rangefinder 10 and the rangefinder rod 20. It can charge the lithium battery with the solar panel 11, providing sufficient support for the power supply of the laser level gauge.
