[0047] Please see Figures 1 to 7 This embodiment provides a winch device, including:

[0048] Hanger 1;

[0049] A winch mechanism, mounted on the gantry 1, is used to hoist the water-collecting robot 7; and

[0050] The detection mechanism includes a sensor 8 and a controller. The sensor 8 is used to detect the height of the component to be tested during the process of the winch mechanism hoisting the water-collecting robot 7. The controller is connected to the sensor 8 and is configured to control the winch mechanism to stop lifting and lowering operations when the sensor 8 detects that the component to be tested has risen to a preset height.

[0051] The above technical solution has the following beneficial effects:

[0052] By real-time monitoring of the height of the component to be tested during the hoisting of the water intake robot 7 by the winch mechanism, and automatically stopping the lifting and lowering operation of the winch mechanism when the preset height is reached, the risk of collision due to excessive lifting is effectively avoided, thus improving operational safety.

[0053] Please see Figure 1 , Figure 2 and Figure 4 In this embodiment, the winch mechanism includes a winch 3, a crossbar 4, and a suspension rope assembly 5. The winch rope 31 of the winch 3 is connected to the crossbar 4, which serves as the component to be tested. The suspension rope assembly 5 is mounted on the crossbar 4 and is used for detachable connection to the water-collecting robot 7. When it is necessary to hoist the water-collecting robot 7, the winch 3 is activated, causing the winch rope 31 to begin winding around the winch 3, thereby gradually tightening the winch rope 31 and driving the crossbar 4 to rise. During the rising process of the crossbar 4 and the water-collecting robot 7, the sensor 8 detects the height of the crossbar 4 (as the component to be tested) in real time and transmits the height information to the controller. When the controller detects that the crossbar 4 has risen to a preset height, it will immediately issue a command to stop the lifting and lowering operation of the winch 3. In this way, the crossbar 4 will not collide with the overhead support 1.

[0054] Please see Figure 4 In this embodiment, the sensor 8 is a proximity sensor 8, and the hanger 1 includes a horizontal frame located at the top. The proximity sensor 8 is located at the bottom of the horizontal frame, directly opposite the horizontal bar 4 located below. The preset height is below the height of the horizontal frame to prevent the horizontal bar 4 from hitting the horizontal frame.

[0055] The hanger 1 also includes front and rear side walls located below the transverse frame. The hanger 1 serves as the supporting structure for the entire device, securely installed in a suitable position. In this embodiment, the front and rear side walls of the hanger 1 can be mounted on the chassis of the drainage truck. A proximity sensor 8 is located at the bottom of the transverse frame, with its sensing surface facing the horizontal bar 4 located below. Thus, when the horizontal bar 4 moves with the lifting and lowering of the winch 31, the proximity sensor 8 can detect the distance between the horizontal bar 4 and the transverse frame in real time and convert this distance information into an electrical signal, which is then transmitted to the controller. The preset height refers to the height threshold at which the proximity sensor 8 triggers an alarm or stops the winch 3 operation. In this embodiment, the preset height is set below the height of the transverse frame to ensure that during the upward movement of the horizontal bar 4, it does not continue to rise and collide with the transverse frame, avoiding potential damage and safety hazards.

[0056] In this embodiment, the proximity sensor 8 is an inductive proximity sensor, and a metal block is disposed on the crossbar for use in conjunction with the inductive proximity sensor. In some embodiments, sensor 8 may be a vision sensor or an ultrasonic ranging sensor.

[0057] In some other embodiments, sensor 8 may detect the height of water-collecting robot 7 (as the measured component) instead of detecting the height of crossbar 4 as described above.

[0058] Please see Figure 1 , Figure 2 and Figure 4 In this embodiment, the length of the crossbar 4 is greater than the width of the transverse frame, so that the crossbar 4 extends beyond the two sides of the transverse frame. Because the crossbar 4 has a certain length, it is adapted to the length or width of the robot, so that the two suspension rope assemblies 5 located on both sides can avoid the shell of the water-collecting robot 7 when hanging down, avoiding the wear problem caused by the suspension rope 51 directly contacting the edge of the robot in existing hoisting methods. Since the crossbar 4 is relatively long, it is also prone to collision with other devices installed on the drainage truck chassis (such as the oil pipe winch 3), so a sensor 8 is installed to monitor and protect it.

[0059] Please see Figures 1 to 7 In this embodiment, the winch mechanism further includes a pulley 2, which is mounted on the transverse frame and can rotate relative to the transverse frame. The winch rope 31 of the winch 3 passes around the pulley 2. Two sets of hoisting rope assemblies 5 are symmetrically arranged on opposite sides of the crossbar 4, and are used to detachably connect to opposite sides of the water-collecting robot 7. The pulley 2 is supported on the transverse frame of the hanger 1 by a shaft, and rotates around itself by the shaft, thereby guiding the movement of the winch rope 31. The rotation of the winch 3 enables the lifting and lowering control of the crossbar 4 and the water-collecting robot 7 suspended on it.

[0060] Please see Figures 2 to 3 In this embodiment, the hoisting rope assembly 5 includes a first connecting ring 52 and a hoisting rope 51. The first connecting ring 52 is connected to the crossbar 4 by bolts, and the hoisting rope 51 is connected to the first connecting ring 52. The hoisting rope 51 extends vertically, and its lower end has a hook and buckle 54 that is detachably connected to the water-collecting robot 7. The first connecting ring 52 is made of high-strength alloy material to ensure that it can withstand sufficient tensile force without deformation or breakage during hoisting. The first connecting ring 52 has a protruding part with a screw hole, and the bolt can be fastened to the crossbar 4 by matching the screw hole. The protruding part of the first connecting ring 52 can abut against the bottom or side wall of the crossbar 4. The hook and buckle 54 adopts a quick locking and releasing mechanism, which can be easily detachably connected to the connection point (such as the hoisting ring 71) on the water-collecting robot 7.

[0061] Please see Figure 4 and Figure 5In this embodiment, the suspension rope assembly 5 further includes a second connecting ring 53, through which the suspension rope 51 is connected to the first connecting ring 52. The second connecting ring 53 is introduced as a connecting intermediary between the suspension rope 51 and the first connecting ring 52, thus forming an indirect connection between the first connecting ring 52 and the suspension rope 51. The second connecting ring 53 is also made of high-strength alloy material to ensure the stability and safety of the connection. The second connecting ring 53 and the first connecting ring 52 are strung together to form a figure-eight shape. Optionally, one or both of the second connecting ring 53 and the first connecting ring 52 can be detachable to facilitate the connection of the connecting rings. In some embodiments, the connecting rings may not need to be detachable.

[0062] Please see Figure 5 Preferably, the second connecting ring 53 is a detachable structure. The second connecting ring 53 includes a U-shaped ring 531 and a connecting pin 532. The U-shaped ring 531 has threaded holes on both sides, and the connecting pin 532 is threaded into the two threaded holes and passes through the first connecting ring 52. This design allows for easy removal or replacement of the second connecting ring 53 and the suspending rope 51 on it.

[0063] Please see Figure 4 In this embodiment, the top of the hanger 1 has a receiving opening 11, and the pulley 2 is located in the receiving opening 11 and connected to the top of the hanger 1 via a bracket 12. The pulley 2 can rotate relative to the bracket 12, and the pulley 2 can be supported on the bracket 12 by an axle. The winch 3 is provided on the side wall of the hanger 1 and located diagonally below the pulley 2. The design of the receiving opening 11 allows the pulley 2 to be compactly installed on the top of the hanger 1, while the winch 3 is located diagonally below the pulley 2. This layout saves installation space.

[0064] Please see Figures 3 to 5 In this embodiment, the lifting rope 51 has two branch ropes 511, and the lower end of each branch rope 511 is connected to a hook buckle 54. The middle part of the lifting rope 51 is hung on the connecting ring, while the two ends of the lifting rope 51 hang down naturally, forming two branch ropes 511, which can share the weight of the object, thereby improving the stability of the lifting process. Figure 4 As shown, the crossbar 4 is along the width direction of the water-collecting robot 7, and the two branch ropes 511 are along the length direction of the water-collecting robot 7.

[0065] Please see Figure 2In this embodiment, the bracket 12 is located in the receiving opening 11, and its end away from the pulley 2 has a groove 121. The groove 121 is engaged and welded to the upper and lower edges of the receiving opening 11. Through the engagement and welding of the groove 121 with the edge of the receiving opening 11, a stable connection is achieved between the bracket 12 and the hanger 1, enabling it to withstand greater tension and torque, thereby improving the overall structural strength of the winch device. In some embodiments, the groove 121 and the edge of the receiving opening 11 can also be bolted together.

[0066] Please see Figure 4 and Figure 7 In this embodiment, the winch device also includes a rotating component 6. The end of the winch rope 31 is connected to the crossbar 4 via the rotating component 6, which is used to rotate the crossbar 4 left and right. The rotating component 6 can be a connecting part with a bearing or sliding mechanism to ensure that the crossbar 4 remains smooth and stable during rotation. The winch device allows the crossbar 4 to rotate left and right manually, enabling adjustment of the position of the water-collecting robot 7. When the crossbar 4 is rotated manually, the rotating component 6 plays a crucial supporting and guiding role. It allows the crossbar 4 to rotate left and right while maintaining its connection with the winch rope 31, without being restricted or interfered with by the winch rope 31.

[0067] Please see Figure 7 In this embodiment, the top of the rotating component 6 has a ring for engaging with the fixing hook at the end of the twisted rope 31. The rotating component 6 has a bearing inside. By fitting the crossbar 4 onto the outer ring of the bearing, the crossbar 4 can be manually moved left and right, causing it to rotate around the rotating component 6.

[0068] Please see Figures 1 to 7 This embodiment also provides a drainage vehicle, including a chassis, a winch device, and a water-collecting robot 7. The winch device is mounted on the chassis, which provides the water-collecting robot 7 with the power required for its operation, such as hydraulic or electrical energy. The winch device is the same as described in any of the above embodiments. The water-collecting robot 7 is hoisted together with the winch device. By integrating the winch device and the water-collecting robot 7, the drainage vehicle can quickly and accurately identify and drain water from narrow and hard-to-reach targets.

[0069] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
