[0002] Polymer composite hydrophobic board is a material used in drainage systems, usually made of polymer materials such as polyethylene (PE), polypropylene (PP) or polyvinyl chloride (PVC). It has good hydrophobic properties, high compressive strength and corrosion resistance, and is widely used in roads, bridges, house construction and other fields.

[0003] In the prior art, in order to ensure that the drainage effect and system operation of the polymer composite hydrophobic plate can remain at a normal level after installation, it is necessary to ensure that each connected hydrophobic plate is always in a horizontal state during the installation process, and no unevenness such as warping and depressions should occur. The flatness of the existing hydrophobic plates during installation generally relies on the technical level and visual perception of the installers, and the reliability is not high. Therefore, in order to assist the installers in leveling the hydrophobic plates during installation, it is necessary to propose a polymer composite hydrophobic plate leveling device.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0019] Reference Figure 1 , 2 3. A polymer composite hydrophobic plate leveling device comprises a bottom plate 1, a counterweight water tank 2 is fixedly installed on the top of the bottom plate 1, a water inlet 3 is arranged on the top of the counterweight water tank 2, a drain pipe 4 is fixedly installed on the lower outer side of the counterweight water tank 2, and a rotary valve is arranged on the drain pipe 4, a lifter 5 is fixedly installed on the top rear side of the bottom plate 1, a lift block 6 is slidably installed on the front side of the lifter 5, a slide groove adapted to the lift block 6 is opened on the front side of the lifter 5, and the lift block 6 is slidably installed in the slide groove, a screw rod 7 is threadedly connected to the lift block 6, a motor 8 is fixedly connected to the top of the screw rod 7, and the lift block 6 A forward extension arm 9 is fixedly installed on the front side, a fixing rod 10 is fixedly installed at the lower front end of the forward extension arm 9, an outer frame 11 is fixedly installed on the four ends of the bottom of the fixing rod 10, a pair of universal wheels 12 are rotatably installed on the inner side of the outer frame 11, the outer ends of the universal wheels 12 abut against a center ball 13, the inner side of the outer frame 11 is rotatably connected with the universal wheels 12 through bearings, the pair of universal wheels 12 on the inner side of the outer frame 11 are respectively inclined toward the center ball 13, and the bottom of the center ball 13 is fixedly connected with a horizontal plate 14 perpendicular to the connecting rod through a connecting rod, and the connecting rod is connected at the center of gravity of the horizontal plate 14.

[0020] Through the above design, before using the device, first place the device at the starting section where the composite hydrophobic plate is laid, and add water to the counterweight water tank 2 to increase the overall stability of the device. At this time, start the motor 8 to drive the screw 7 to rotate to control the lifting block 6 to move up and down, so as to adjust the components connected to the front end of the lifting block 6 to a suitable height position. After the height adjustment is completed, leave the device alone for a while. At this time, since the outer periphery of the center ball 13 rolls and abuts against multiple sets of universal wheels 12, the center ball 13 will automatically rotate under the influence of the deadweight of the bottom horizontal plate 14 to keep the horizontal plate 14 always in a horizontal state.

[0021] Reference Figure 1 , 23. A laser pen 15 is fixedly installed on the front end of the horizontal plate 14, a universal level 16 is fixedly installed on the top rear side of the horizontal plate 14, a holder 17 is fixedly installed on the rear side of the lifter 5, a detection plate 18 is placed on the top of the holder 17, and the fitting surfaces of the holder 17 and the detection plate 18 are respectively provided with strong magnetic sheets with opposite magnetism, and a scale 19 is provided on the detection plate 18.

[0022] Through the above design, based on the function that the center ball 13 described above automatically rotates to keep the horizontal plate 14 always in a horizontal state, the installer can now check whether the horizontal plate 14 has been automatically leveled by observing whether the bubble in the middle of the universal level 16 on the top of the horizontal plate 14 is centered. When the bubble is in the middle, the detection plate 18 on the top of the holder 17 is taken out, and the detection plate 18 is placed against the starting and ending positions of the first hydrophobic plate along the direction of the laser emitted by the laser pen 15 on the horizontal plate 14. At this time, the laser is hit at two positions on the detection plate 18, and the height difference between the two laser points is calculated in combination with the scale 19 to determine whether the installation of the hydrophobic plate is horizontal. Similarly, the subsequent second, third and other hydrophobic plates also perform the same operation and combine the data of the previous hydrophobic plate for comprehensive horizontal judgment, so as to assist the installer to effectively adjust the horizontality of the hydrophobic plate during installation, thereby improving the installation flatness of the hydrophobic plate.

[0023] The implementation principle of the embodiment of the present application is:

[0024] First, before using this device, place it at the starting section where the composite hydrophobic plate is laid, and add water to the counterweight water tank 2 to increase the overall stability of the device. At this time, start the motor 8 to drive the screw 7 to rotate to control the lifting block 6 to move up and down, so as to adjust the components connected to the front end of the lifting block 6 to a suitable height position. After the height adjustment is completed, leave the device alone for a while. At this time, since the outer periphery of the center ball 13 rolls and abuts against multiple sets of universal wheels 12, the center ball 13 will automatically rotate under the influence of the deadweight of the bottom horizontal plate 14 to keep the horizontal plate 14 always in a horizontal state.

[0025] Based on the above, the installer can check whether the horizontal plate 14 has been automatically leveled by observing whether the bubble in the middle of the universal level 16 on the top of the horizontal plate 14 is centered. When the bubble is in the middle, take out the detection plate 18 on the top of the holder 17, and place the detection plate 18 against the starting and ending positions of the first hydrophobic plate along the direction of the laser emitted by the laser pen 15 on the horizontal plate 14. At this time, the laser is hit at two positions on the detection plate 18, and the height difference between the two laser points is calculated in combination with the ruler 19 to determine whether the installation of the hydrophobic plate is horizontal. Similarly, the subsequent second, third and other hydrophobic plates also perform the same operation and combine the data of the previous hydrophobic plate to make a comprehensive horizontal judgment, so as to assist the installer to effectively adjust the horizontality of the hydrophobic plate during installation, thereby improving the installation flatness of the hydrophobic plate.

[0026] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
