[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0018] like Figure 1-3 A bridge deck guardrail watering maintenance device is shown, including a water tank 10, which is installed on the chassis 3 of a watering trolley. Four wheels 13 are provided at the bottom of the chassis 3, and a water inlet 5 is provided at the top of the water tank 10. A water suction pump 15 is provided inside the water tank 10, and the water suction pump 15 is connected to a spray pipe 2. The other end of the spray pipe 2 extends to the outside of the water tank 10, and the other end of the spray pipe 2 is provided with three strip spray ports 1. The watering trolley is provided with an enclosure around the water tank 10, and the enclosure includes four vertical poles 8, and adjacent vertical poles 8 are connected by horizontal partitions 9.

[0019] Furthermore, the water storage tank 10 is provided with a solar panel 7, and the solar panel 7 is installed on the enclosure through a support frame 12. The water storage tank 10 is also provided with a liquid level relay 14, a temperature sensor 11, a power switch box 4 and a control panel 6.

[0020] When the bridge deck guardrail watering and maintenance device is actually used, the water inlet 5 is convenient for the water storage tank 10 to replenish or discharge water. The water inlet 5 also serves as the delivery port and lifting port of the liquid level relay 14 and the water suction pump 15. Water is pumped out by the water suction pump 15 and transported to the strip spray port 1 through the spray main pipe 2 to spray the guardrail with water for maintenance.

[0021] When exposed to sunlight, the solar panel 7 converts solar energy into electrical energy. Part of the energy is stored in the solar panel 7, part of it is used to receive information and output commands from the control panel 6, part of it is used for the water suction pump 15 to absorb water, part of it is used for the driving force and braking force of the wheel 13, part of it is used for the temperature sensor 11 to feedback the external atmospheric temperature information, and part of it is used for the liquid level relay 14 to monitor the water level elevation of the water tank 10.

[0022] The power switch box 4 is used to control the cutting off and transmission of the current of the sprinkler maintenance device. When a fault such as leakage or short circuit occurs, the power supply is cut off to ensure the safe use of the sprinkler maintenance device.

[0023] The control panel 6 can be used to control the wheel 13. The round-trip distance of the wheel 13 and the number of round-trip rounds of the wheel 13 in each maintenance period are output on the control panel 6. The PLC control system controls the wheel 13 to execute the instructions issued by the control panel 6; the control panel 6 can control the single water suction working duration of the water suction pump 15 according to the number of round-trip rounds of the wheel 13.

[0024] The temperature sensor 11 can transmit the temperature to the control panel 6 in real time. After information processing, the control panel 6 issues different work instructions to the wheel 13 and the water suction pump 15 according to different temperature thresholds. The control panel 6 can set four temperature thresholds, which are 15-25℃, 25-30℃, 30-35℃, 35℃ and above (the large value does not include this value). The four temperature thresholds correspond to the work instructions issued by the control panel 6, namely, the number of walking rounds of a single wheel 13 in the maintenance section is 3 times, the number of walking rounds of a single wheel 13 in the maintenance section is 5 times, the number of walking rounds of a single wheel 13 in the maintenance section is 8 times, and the number of walking rounds of a single wheel 13 in the maintenance section is 12 times.

[0025] The liquid level relay 14 can monitor the liquid level elevation of the water tank 10. When the liquid level reaches the set value, the working power of the water suction pump 15 is immediately interrupted to prevent the water suction pump from idling and burning the fuselage. The interruption command issued by the liquid level relay 14 is higher than the normal command issued by the control panel 6. At the same time, the interruption command issued by the liquid level relay 14 is fed back to the control panel 6, which is linked to stop the movement command of the wheel 13.

[0026] The above are only implementation methods of the present utility model, and are not intended to limit the patent scope of the present utility model. Any equivalent structure made using the contents of the specification and drawings of the present utility model, directly or indirectly used in other related technical fields, are also within the patent protection scope of the present utility model.
