DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor are involved in the protection scope of the utility model.
[0022] The prior art only relies on the extension and retraction of the extension end of the air cylinder to control the automatic lifting of the water suction scraper, and the safety is low, and the main reason is that the extension end of the air cylinder has a relatively large probability of sudden drop after long-time use, which is usually related to sealing failure, unstable air pressure and wear factors. Please refer to Figures 1-4 The embodiment provides a lifting mechanism for a water suction scraper, which comprises a machine board 1 and a water suction scraper mounting plate 2. Before use, the machine board 1 is installed on the scrubber, and then the water suction scraper is installed below the water suction scraper mounting plate 2.
[0023] Reference Figure 1 As shown in the figure, the surface of the machine board 1 is provided with a moving mechanism 3 for controlling the lifting of the water suction scraper mounting plate 2. The moving mechanism 3 comprises an air cylinder 31 fixed on the surface of the machine board 1. The extension end of the air cylinder 31 is fixedly connected with a moving plate 32. The water suction scraper mounting plate 2 is fixedly connected with the moving plate 32. The same moving plate 41 is fixed on the outer wall of the extension end of the air cylinder 31. The extension end of the air cylinder 31 is started to drive the moving plate 32 to move downward. The downward movement of the moving plate 32 can drive the water suction scraper mounting plate 2 and the water suction scraper installed at the bottom of the water suction scraper mounting plate 2 to move downward, so that the water suction scraper is in full contact with the ground.
[0024] Reference Figures 1-4As shown, the existing technology relies solely on the extension and retraction of the cylinder 31 to control the automatic lifting and lowering of the squeegee, which has low safety. The main reason is that the extension and retraction of the cylinder 31 is likely to suddenly fall after long-term use. This situation is usually related to seal failure, unstable air pressure, and wear factors. In order to improve the reliability of the squeegee during operation, the following settings are made: a protective mechanism 4 that locks the lifting and lowering position of the squeegee mounting plate 2 in conjunction with the moving mechanism 3. The protective mechanism 4 includes two convex plates 42 symmetrically fixed on the surface of the mounting plate 1. A moving plate 41 is provided between the two convex plates 42. The interior of each of the two convex plates 42 is provided with a rectangular groove that runs through the left and right sides. The interior of the mounting plate 1 is provided with a cylindrical groove that communicates with the rectangular groove. A locking plate 43 is provided inside the rectangular groove. The outer wall of the locking plate 43 is provided with a limiting component that allows it to slide along the inner wall of the rectangular groove. The limiting component includes a slider fixed on the locking plate 43. A sliding groove for the slider to slide is provided laterally on the inner wall of the rectangular groove. Both sides of the sliding plate 41 are provided with locking grooves 47. Inside the cylindrical groove is a power assembly 44 that pushes the locking plate 43 into the locking groove 47. The power assembly 44 includes a connecting rod 442 fixed to the side of the locking plate 43 and an elastic plate 441. The connecting rod 442 is located inside the elastic plate 441. The end face of the elastic plate 441 is fixedly connected to the inner wall of the rectangular groove. Inside the locking groove 47 is a spring-detecting mechanism 45 that detects the elasticity of the elastic plate 441. An electromagnet 443 is fixedly installed on the end face of the connecting rod 442. The electromagnet 443 is slidably sleeved inside the cylindrical groove. A permanent magnet 444 is fixedly installed on the inner wall of the cylindrical groove. When the electromagnet 443 is energized, it attracts the permanent magnet 444. When the extension end of cylinder 31 drives the squeegee to make full contact with the ground, it pauses, ensuring the stability of the squeegee during operation. After pausing at a specific position, the power to electromagnet 443 is turned off, cutting off the attraction between electromagnet 443 and permanent magnet 444, so that elastic sheet 441 is not squeezed. This mechanism ensures that electromagnet 443 will not maintain attraction in the absence of power, thus allowing elastic sheet 441 to function. When elastic sheet 441 is not squeezed, it pulls electromagnet 443 back to its original position, while connecting rod 442 pushes locking plate 43 to extend into locking groove 47, forming a physical locking mechanism to prevent the squeegee from accidentally falling during operation due to failure of the extension end of cylinder 31.
[0025] refer to Figures 2-4As shown, the ballistic testing mechanism 45 includes a pressure testing rod 451 fixed to the side of the locking plate 43. The inner wall of the locking groove 47 is provided with a rod groove 452. A pressure sensor 453 is fixedly installed on the inner wall of the rod groove 452. After the locking plate 43 extends into the locking groove 47 through the elastic sheet 441, the pressure testing rod 451 is inserted into the rod groove 452 and squeezes the pressure sensor 453. The reading of the pressure sensor 453 can reflect the elastic effect of the elastic sheet 441, thereby further ensuring the effectiveness of the protective mechanism 4. If the elasticity of the elastic sheet 441 is kept within a reasonable range, it means that the protective mechanism 4 is operating normally and can effectively prevent accidental falling and enhance overall safety. If it is outside the reasonable range, the elastic sheet 441 needs to be replaced.
[0026] refer to Figure 3 As shown, a pressure sensor 46 is fixedly installed on the top of the locking plate 43 to monitor the operating status of the telescopic end of the cylinder 31. The locking plate 43 extends into the locking groove 47 but does not contact its inner wall. When the telescopic end of the cylinder 31 fails, the moving plate 41 will move down synchronously and apply pressure to the pressure sensor 46. The pressure sensor 46 will then transmit a signal to the external controller and issue an alarm. At the same time, the locking plate 43 and the locking groove 47 can prevent the squeegee from falling accidentally due to the failure of the cylinder 31, thus providing additional safety protection.
[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
