[0002] In modern household and commercial cleaning solutions, automated sweepers have become an important tool for improving cleaning efficiency and reducing labor intensity. Its core components, brush discs and scraper strips, are crucial to the cleaning effect. However, the current brush discs and scraper strips usually use separate manual testing processes, which is not only time-consuming and labor-intensive, but the test results are greatly affected by subjective factors, making it difficult to ensure the accuracy and consistency of the test. Although there have been attempts on the market to design independent test devices for brush discs and scraper strips, such as the PCB ceramic brush service life test device disclosed in patent CN201821578191.X, these devices can often only be tested one by one, and synchronous detection cannot be achieved, and the overall test efficiency is not high enough.

DETAILED DESCRIPTION

[0021] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the implementation modes are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0022] This embodiment provides a sweeper vehicle testing device with automatic drainage function, such as Figures 1 to 5 , including a control device, a position sensor, a drainage component, a rotating bracket component and a rotating drive component. The rotating drive component, the drainage component and the position sensor are all connected to the control device by signal. The sweeping vehicle is installed on the rotating bracket component. The rotating drive component controls the movement of the sweeping vehicle through the rotating bracket component; the drainage component is installed on the sweeping vehicle. The position sensor is used to detect the moving position of the sweeping vehicle and transmit the detection data to the control device. When it is detected that the sweeping vehicle moves to the set position, the control device controls the rotating drive component to stop working and controls the drainage component to perform drainage.

[0023] Specifically, the present embodiment drives the rotating bracket assembly to move through the rotating drive assembly, and then drives the sweeper to move through the rotating bracket assembly. The use and wear of the cleaning structure in actual applications can be simulated during the movement of the sweeper. In addition, the present embodiment is further provided with a drainage assembly. In order to achieve an effect closer to actual use, the water outlet function of the sweeper itself can be utilized, that is, the sweeper will provide a certain amount of clean water to the brush plate and the scraper bar when working, and a general sweeper does not have an automatic drainage function. Therefore, if actual use is to be simulated and fully automatic testing is to be realized, the present embodiment is provided with an automatic drainage assembly, and the sweeper is provided with a position sensor. The installation position of the position sensor is not limited in this embodiment, as long as the position of the sweeper can be detected. The staff places a drainage trough according to the site conditions. When the sweeper is detected to move to the position of the trough, the control device stops the rotary drive assembly, thereby stopping the sweeper. Then the control device starts the drainage assembly, which includes a water outlet pipe 11 and a water outlet control valve 12. The water outlet control valve 12 is installed at the outlet of the water outlet pipe 11. The water outlet control valve 12 is connected to the control device signal. The sewage of the sweeper is discharged through the water outlet pipe 11, that is, the control device opens the water outlet control valve 12, and the sewage is discharged to the trough through the water outlet pipe 11. The drainage time can be set. When the time is up, the control device closes the water outlet control valve 12, restarts the rotary drive assembly, and continues the wear test. This embodiment can achieve a fully automatic simulation of the actual use of the sweeper, and can efficiently achieve the detection purpose and achieve more accurate detection results.

[0024] Furthermore, in order to ensure the assembly stability of the water outlet pipe 11 and fix the position of the water outlet, the present embodiment is further provided with a support plate 13, such as Figure 5 As shown, the support plate 13 is fixed to the sweeper, the support plate 13 is provided with a mounting hole, the water outlet pipe 11 is provided with a limiting ring 14, the outlet of the water outlet pipe 11 is assembled in the mounting hole, and the limiting ring 14 is located above the mounting hole, thereby fixing the position of the water outlet to ensure normal drainage function.

[0025] In this embodiment, Figures 1 to 3 The rotating bracket assembly includes a central pillar 1 and at least one rotating bracket 2. The rotating drive assembly is installed on the central pillar 1. One end of the rotating bracket 2 is connected to the sweeping vehicle to be tested, and the other end of the rotating bracket 2 is drivingly connected to the output end of the rotating drive assembly. The rotating drive assembly is used to drive the rotating bracket 2 to rotate around the central pillar 1 to control the movement of the sweeping vehicle.

[0026] Specifically, Figure 1As shown, the central pillar 1 is fixed to the ground, and the central pillar 1 is used as the center of movement of the sweeping vehicle. The sweeping vehicle is controlled to move in a circle within the length range of the rotating bracket 2 to realize automatic wear test of the cleaning structure of the sweeping vehicle, that is, life test. By controlling the movement of the sweeping vehicle, the test result closest to the actual can be obtained.

[0027] Among them, the rotating drive assembly of this embodiment includes a connecting member 3, a conductive ring 4 and a bearing 5, the conductive ring 4 is installed on the central pillar 1, the bearing 5 is sleeved on the central pillar 1, the connecting member 3 is installed on the output end of the conductive ring 4, and the connecting member 3 and the bearing 5 are both fixedly connected to the rotating bracket 2.

[0028] Specifically, Figure 3 As shown, the conductive ring 4 of this embodiment is the prior art. Through the characteristics of the conductive ring 4, the phenomenon of wire entanglement in the process of driving the rotating bracket 2 to rotate can be avoided. The rotating bracket 2 can be fixed to the connecting piece 3 by welding, and the conductive ring 4 drives the connecting piece 3 to rotate, and the connecting piece 3 can drive the rotating bracket 2 to rotate. Furthermore, in order to ensure smooth rotation, the rotating bracket 2 is also connected to a bearing 5, and the bearing 5 preferably adopts a self-aligning bearing. The so-called self-aligning bearing refers to a bearing 5 whose ring raceway is spherical and can adapt to the angular deviation movement between the axis lines of the inner and outer raceways. It mainly bears radial loads and can also bear a small amount of bidirectional axial loads. Therefore, during the rotation of the rotating bracket 2, a radial force may be generated on the bearing 5, and the self-aligning bearing can automatically adjust to ensure the smooth rotation of the rotating bracket 2, thereby allowing the sweeper to move smoothly.

[0029] Furthermore, in order to improve the efficiency of detection, the rotating bracket 2 of this embodiment can be set to two or more than two, such as Figure 1 and Figure 2 As shown, in this embodiment, two rotating brackets 2 are taken as an example, and two groups of rotating drive components are correspondingly provided. In order to ensure that the two rotating brackets 2 can rotate synchronously, a synchronization component is provided to prevent the collision of the two sweepers. The synchronization component includes a synchronization link 6 and a fixing member 7. The rotating bracket 2 is provided with the fixing member 7. The two ends of the synchronization link 6 are respectively provided on different fixing members 7. Specifically, as shown in FIG. Figure 1 As shown, the two rotating brackets 2 are connected by a synchronous connecting rod 6 so that the two rotating brackets 2 are linked. Therefore, when the conductive ring 4 is started at the same time, the two rotating brackets 2 can also rotate synchronously, and the two sweepers can perform the test work in an orderly manner.

[0030] like Figure 1 and Figure 4The sweeping vehicle of the present embodiment is equipped with a connecting assembly, which includes a connecting rod 8 and a locking piece 9. One end of the connecting rod 8 is welded to the sweeping vehicle, and the rotating bracket 2 is provided with a hollow connecting tube 10. The hollow connecting tube 10 is sleeved on the outer periphery of the connecting rod 8, and the hollow connecting tube 10 is locked to the connecting rod 8 by the locking piece 9.

[0031] Specifically, the sweeping vehicle of this embodiment is mainly used for testing, so for the convenience of assembly, a connecting assembly is installed on the sweeping vehicle, and one end of the connecting rod 8 can be fixed to the sweeping vehicle by welding, or can be locked to the sweeping vehicle by screws, etc., according to actual needs. During assembly, the connecting rod 8 is inserted into the hollow connecting tube 10 of the rotating bracket 2, and then locked by the locking member 9 to complete the assembly work. The structure is simple and the disassembly and assembly are convenient.

[0032] As another implementation of this embodiment, this embodiment can also drive the central pillar 1 to rotate by setting a motor, and the rotating bracket 2 is fixed to the central pillar 1. The central pillar 1 drives the rotating bracket 2 to rotate, which can also achieve the purpose of driving the sweeper to move automatically, as long as the structure of the central pillar 1 can be stabilized.

Although the utility model is disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content disclosed above without departing from the scope of the technical solution of the utility model.
