Description

Technical Field

[0001] The utility model belongs to the technical field of drainage robots and relates to a high-efficiency energy-saving drainage robot. Background Art

[0002] 1. Since the hydraulically driven drainage robot adopts hydraulic drive, whether the hydraulic oil temperature can be effectively controlled is the key to whether the drainage robot can work stably for a long time. Under the existing technical conditions, in order to reduce the temperature of the hydraulic oil, some drainage robots introduce the hydraulic oil return pipe into the outlet pipe of the drainage pump and distribute it spirally on the inner wall of the outlet pipe. When the water flows through the outlet pipe, the water will cool the pipe, thereby taking away part of the heat of the hydraulic oil and playing a certain cooling role on the hydraulic oil. However, its disadvantages are also very obvious. First, the length of the return pipe in the outlet pipe is limited, and the contact area with the water is also limited. The actual cooling effect on the hydraulic oil is limited, and the lasting and effective cooling effect cannot be achieved, resulting in the drainage robot being unable to operate stably for a long time. It needs to be shut down every few hours and restarted when the hydraulic oil temperature naturally drops to a certain temperature, which has a certain restriction on the efficiency of emergency drainage; second, because the hydraulic oil pipe is spirally arranged in the outlet pipe, the outlet pipe itself will have a certain impact on the flow and lift of the drainage pump, especially when the water flows through the spiral cooling pipe, it will produce friction resistance with each oil pipe, thereby reducing the effective lift of the drainage pump and failing to achieve the required drainage height and drainage distance. 2. Some water supply and drainage robots cool the hydraulic oil in the hydraulic system by installing a fan cooling method on the power mother vehicle. This cooling method can achieve a good cooling effect, but the disadvantage is that it will consume the power of the power mother vehicle and increase the manufacturing cost of the overall equipment.

DETAILED DESCRIPTION

[0029] like Figure 1-Figure 3 , Figure 8 As shown, a high-efficiency energy-saving drainage robot includes a mobile chassis 1, a drainage mechanism 2 and a hydraulic system 3 for providing power. The mobile chassis 1 is also provided with a hydraulic oil cooler 4 connected to the oil return circuit of the hydraulic system 3. The water outlet end of the drainage mechanism 2 is connected to the hydraulic oil cooler 4 through a cooler water inlet pipe 5, and the water intake end of the drainage mechanism 2 is connected to the hydraulic oil cooler 4 through a cooler water outlet pipe 6.

[0030] In the utility model, by arranging a hydraulic oil cooler 4 on the mobile chassis 1, the low-temperature and high-pressure water flow in the drainage mechanism 2 can be introduced into the chamber 31 of the hydraulic oil cooler from the water outlet end of the drainage mechanism 2 through the cooler water inlet pipe 5, and at the same time, the high-temperature and high-pressure hydraulic oil in the return oil circuit of the hydraulic system 3 is introduced into the hydraulic oil cooler 4, and the low-temperature and high-pressure water flow in the drainage mechanism 2 is fully heat exchanged with the high-temperature and high-pressure hydraulic oil, so as to achieve the purpose of quickly cooling the hydraulic oil in the hydraulic oil cooler, and the high-pressure water flow after absorbing heat can be discharged to the water suction end of the drainage mechanism through the cooler water outlet pipe 6 and discharged through the drainage mechanism, which will not affect the head of the drainage mechanism and will not consume the power of the mobile chassis 1.

[0031] Specifically, a hydraulic oil cooling pipeline 30 is provided in the hydraulic oil cooler 4, and the two ends of the hydraulic oil cooling pipeline 30 are respectively connected to the oil inlet pipe 7 and the oil outlet pipe 8, and the oil inlet pipe 7 is connected to the oil return line of the hydraulic system 3, and the hydraulic oil cooling pipeline 30 is a copper pipe. A plurality of hydraulic oil cooling pipelines 30 are provided in the hydraulic oil cooler, and the two ends of the plurality of hydraulic oil cooling pipelines 30 are integrated into the same inlet and outlet. By utilizing the high heat conduction efficiency of the copper pipe and the advantage of the large overall heat dissipation area of ​​the plurality of copper pipes, the high-temperature hydraulic oil in the copper pipe can fully exchange heat with the high-pressure and low-temperature water flow in the chamber 31 of the hydraulic oil cooler, thereby achieving the purpose of rapidly cooling the hydraulic oil in the copper pipe.

[0032] Specifically, the hydraulic system 3 includes a multi-way control valve, a hydraulic motor, and a hydraulic oil tank. The hydraulic motor and the hydraulic oil tank are connected to the multi-way control valve through connecting pipes. The output oil circuit of the hydraulic system 3 is connected to the drainage mechanism 2 and the mobile chassis. The return oil circuit of the hydraulic system 3 is connected to the hydraulic oil cooling pipeline 30 through the oil inlet pipe 7, and the hydraulic oil cooling pipeline 30 is connected to the multi-way control valve through the oil outlet pipe 8.

[0033] Specifically, the drainage mechanism 2 includes a drainage pump 10 arranged on the mobile chassis 1, the drainage pump motor 11 is connected to the hydraulic system 3, the inner wall of the suction end of the drainage pump 10 is provided with a water outlet connected to the cooler outlet pipe 6, and the inner wall of the outlet end of the drainage pump 10 is provided with a water inlet connected to the cooler inlet pipe 5. Under the hydraulic power of the hydraulic system, the drainage pump motor 11 can work to suck water from the suction end of the drainage pump and discharge it from the outlet end of the drainage pump. A water inlet and a water outlet are respectively arranged on the inner wall of the outlet end and the inner wall of the suction end so that part of the low-temperature high-pressure water discharged from the outlet end can flow from the water inlet into the cooler inlet pipe 5, and then enter the hydraulic oil cooler for heat exchange, and then flow back to the suction end of the drainage pump through the cooler outlet pipe and the water outlet. Such a structural arrangement can minimize the impact on the water flow and head in the outlet end.

[0034] Preferably, the outer end of the water suction end of the drainage pump 10 has an inclined water suction port extension pipe 12, the end of the water suction port extension pipe 12 is horizontally arranged, and the water suction port extension pipe 12 is detachably arranged. The water suction port extension pipe 12 can extend the water suction port of the drainage pump, and at the same time, the end of the water suction port extension pipe 12 is designed to be horizontal and parallel to the ground, so that the drainage pump can almost drain the water on the ground under negative pressure; the water suction port extension pipe 12 is detachably arranged, and the water suction port extension pipe 12 of different lengths can be replaced or the water suction port extension pipe 12 can be disassembled to cope with different application environments. In this way, when heavy rainfall causes waterlogging and causes water in the municipal pipe network to flow out of the municipal kiln well onto the road surface, the shorter extension pipe of the drainage pump can be replaced with a longer extension pipe, which is inserted into the municipal kiln well. Under the action of atmospheric pressure, continuous large-flow drainage can be achieved, thereby reducing the water level in the municipal pipe network.

[0035] Specifically, the mobile chassis 1 includes a crawler chassis 13 connected to the hydraulic system 3 .

[0036] Preferably, combined Figure 4-Figure 7 As shown, the crawler chassis 13 is connected to the drainage pump 10 through a multi-directional moving mechanism 14. The multi-directional moving mechanism 14 enables the drainage mechanism to move forward and backward and up and down. The upward movement can ensure that the robot does not touch the ground due to the small ground clearance of the water suction port during the movement; the downward movement can ensure that the water suction port of the drainage pump can reach the water accumulation below the robot chassis to absorb water; the forward movement can enable the robot to move the water suction port of the drainage pump forward without moving the chassis. When encountering a narrow space drainage scene, the drainage pump can stretch its neck to remove the accumulated water in the area that the robot cannot reach.

[0037] Specifically, the multi-directional moving mechanism 14 includes a front-to-back moving frame 15, the two ends of which are slidably matched with the crawler chassis 13 through the front-to-back moving slide rails 16, the front-to-back moving frame 15 is provided with an up-and-down moving slide rail 17, the up-and-down moving frame 18 is slidably matched on the up-and-down moving slide rail 17, the drainage pump 10 is fixed on the up-and-down moving frame 18, and the hydraulic oil cooler 4 is provided with two and symmetrically fixed at the two ends of the up-and-down moving frame 18. The front-to-back moving frame 15 cooperates with the front-to-back moving slide rails 16 to realize the front-to-back movement of the front-to-back moving frame and the drainage pump arranged on the front-to-back moving frame, and the up-and-down moving slide rails 17 on the front-to-back moving frame 15 cooperate with the up-and-down moving frame 18 to realize the up-and-down movement of the drainage pump.

[0038] Specifically, the crawler chassis 13 is provided with a forward and backward moving hydraulic cylinder 19 connected to the forward and backward moving frame 15, the output shaft end of the forward and backward moving hydraulic cylinder 19 is hinged to the forward and backward moving frame 15, and the end of the forward and backward moving hydraulic cylinder 19 away from the output shaft is hinged to the crawler chassis 13; the forward and backward moving frame 15 is also provided with two vertically arranged up and down moving hydraulic cylinders 20, and the output shaft end of the up and down moving hydraulic cylinder 20 is connected to the up and down moving frame 18. The forward and backward moving hydraulic cylinder 19 can drive the forward and backward moving frame 15 to translate forward and backward along the forward and backward moving slide rail, and the up and down moving hydraulic cylinder can drive the up and down moving frame to move up and down along the up and down moving slide rail.

[0039] Preferably, combined Figure 2 and Figure 3 As shown, an emergency towing hook 21 and a self-rescue hydraulic winch 22 are also provided on the crawler chassis 13. The emergency towing hook 21 and the self-rescue hydraulic winch 22 can realize the emergency rescue of the robot.
