Description

Technical Field

[0001] This utility model relates to the field of water conservancy equipment technology, specifically to a walking positioning device and a trash rack cleaning system. Background Technology

[0002] In many industrial applications, such as hydropower stations and sewage treatment plants, the cleaning of trash racks is crucial. Grab bucket trash rack cleaners, as a common cleaning equipment, are widely used to remove debris from trash racks to ensure smooth water flow and the normal operation of related equipment. Existing grab bucket cleaning machines typically rely on a walking mechanism to move within a specific area, enabling cleaning operations at different locations. However, several problems exist in the walking and positioning process: over long-term use, dust, dirt, and other impurities easily accumulate on the surface of the positioning markers. These impurities can interfere with the sensor's recognition of the markers, further affecting the accuracy of positioning. Therefore, we have made improvements to address this issue by proposing a walking positioning device and a trash rack cleaning system. Utility Model Content

The sensor is electrically connected to the electronic control system.

[0006] As a preferred technical solution in this application, buffers are installed at both ends of the frame.

[0016] Example 1, as shown in the attached document Figures 1-4 As shown, this utility model provides a walking positioning device, including: a walking mechanism and a sensor 4 disposed on the walking mechanism, the sensor 4 being electrically connected to the walking mechanism; a marker 5 for use with the sensor 4 is disposed in the target parking area of ​​the walking mechanism; an air jet bend 604 is disposed next to the sensor 4, and the air jet bend 604 is connected to an air supply component, which is used to supply compressed air to the air jet bend 604 to clean the surface of the marker 5 with compressed air; two markers 5 are disposed, and the two markers 5 are spaced apart along the moving direction of the walking mechanism according to the deceleration buffer distance of the walking mechanism; this application achieves non-contact cleaning by distributing the air jet bend 604 next to the sensor 4 and connecting the air jet bend 604 to the air supply component, which is used to supply compressed air to the air jet bend 604 to clean the surface of the marker 5 with compressed air.

[0017] The deceleration buffer distance is the distance between the two markers 5 along the direction of movement of the traveling mechanism. It is the distance the traveling mechanism needs to travel from its highest speed to a low speed.

[0018] Furthermore, there are two sensors 4, which are spaced apart along the moving direction of the walking mechanism, and the interval between the two sensors 4 matches the interval between the two markers 5, so that the walking mechanism can decelerate after the sensor 4 senses one of the markers 5, and can brake after the sensor 4 senses the other marker 5.

[0019] Furthermore, the surface of the marker 5 is positioned upwards, and the sensing end of the sensor 4 is positioned downwards. The sensor 4 is a Hall proximity switch, and the marker 5 is a magnetic component.

[0020] Furthermore, the traveling mechanism includes a frame 1, a drive system 2, and an electronic control system 3. The drive system 2 and the electronic control system 3 are mounted on the frame 1. The drive system 2 is used to drive the frame 1 to move. The electronic control system 3 is electrically connected to the drive system 2 and is used to control the operation of the drive system 2. The sensor 4 is electrically connected to the electronic control system 3. The drive system 2 is the power part of the traveling mechanism. It uses a variable frequency motor as the drive motor and works with the transmission structure to drive the frame 1 to move. Its specific structure is the same as the power part of the traveling mechanism in the prior art, and will not be described in detail here. The sensor 4 is specifically electrically connected to the electronic control system 3 in the traveling mechanism. The electronic control system 3 controls the drive system 2 to perform corresponding operations through the signal fed back by the sensor 4, so as to achieve the above-mentioned deceleration and braking.

[0021] Furthermore, a bracket 11 is provided on the frame 1, and a mounting bracket 6 is provided on the side of the bracket 11 near the sensor 4. The sensor 4 is mounted on the mounting bracket 6. The mounting bracket 6 is connected to the bracket 11 by welding or bolting. The bracket 11 is welded to the frame 1. Both ends of the frame 1 are equipped with buffers 101. The buffers 101 are made of polyurethane buffers, which can improve the safety of the frame 1 during operation.

[0022] Furthermore, an external threaded pipe 601 is inserted and connected to the mounting bracket 6. The bottom end of the external threaded pipe 601 is fixedly connected to the jet elbow 604, and the top end of the external threaded pipe 601 is threadedly connected to a threaded connector 602. The threaded connector 602 is connected to an air supply pipe 603, and one end of the air supply pipe 603 is connected to an air compressor through a solenoid valve. The air compressor provides compressed air to the jet elbow 604. Specifically, the compressed air generated by the air compressor passes through the solenoid valve and the air supply pipe 603 to reach the external threaded pipe 601, and then is sprayed out by the jet elbow 604 to clean the surface of the marker 5.

[0023] Furthermore, the electronic control system 3 has a protective enclosure, and the air compressor and solenoid valve are both installed inside the protective enclosure of the electronic control system 3. The air compressor and solenoid valve are both connected to the electronic control system 3, so that the solenoid valve and the air compressor are also controlled by the electronic control system 3. It should be noted that the control of the solenoid valve and the air compressor does not interfere with the control of the traveling mechanism.

[0024] Furthermore, the outer surface of the externally threaded tube 601 is connected to two fastening nuts 605, and both fastening nuts 605 abut against the mounting bracket 6, thereby fixing the externally threaded tube 601 through the fastening nuts 605.

[0025] Example 2: This utility model also provides a trash rack cleaning system, including a grab bucket cleaning machine and a walking positioning device. The grab bucket cleaning machine is mounted on a walking mechanism, and two markers 5 are set in the target working area of ​​the grab bucket cleaning machine, such as the opening of a trash rack at the water inlet of a hydropower station. The grab bucket cleaning machine is existing technology, which includes a lifting device and a cleaning grab bucket connected to the lifting device. The working principle is the same as that of existing technology. The specific structure, principle and setting method will not be described in detail here. Because the trash rack cleaning system is equipped with the above-mentioned walking positioning device, the braking positioning accuracy of the grab bucket cleaning machine is higher, which can facilitate the alignment of its cleaning grab bucket with the trash rack bars without manual intervention, greatly reducing the labor intensity of workers, improving cleaning efficiency and increasing the power generation benefits of the power station.

[0026] Further details are attached. Figure 1 As shown, it also includes a track 7 set along the moving direction of the walking mechanism, with the walking mechanism located on the track 7 to facilitate the guidance of the movement of the walking mechanism.
