DETAILED DESCRIPTION

[0015] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0016] See also Figure 1 and Figure 2, the present invention provides a technical solution: an Internet of Things code-scanning encrypted intelligent weighing system, including a weighing platform 1. Vertical plates 3 for restricting the position of wheels are fixed at both edges of the upper surface of the weighing platform 1. Installing the vertical plates 3 on the weighing platform 1 facilitates restricting the wheels on the weighing platform 1, playing a role in preventing cheating.

[0017] A bottom box 10 for storing moisture is provided below the weighing platform 1. A perforated plate 11 is installed at the upper position inside the bottom box 10. A plurality of support rods 12 are evenly installed on the lower surface of the perforated plate 11. The lower ends of the support rods 12 extend into the bottom box 10 and are fixedly connected to the bottom box 10. The support rods 12 achieve balanced support for the perforated plate 11, improving the structural stability of the perforated plate 11.

[0018] A plurality of pressure sensors 14 for collecting the weight of the vehicle are evenly installed between the perforated plate 11 and the weighing platform 1. The working principle of the pressure sensors 14 and the connection method with devices such as the display have been fully disclosed in the prior art, so details are not described here.

[0019] A first limiting plate 8 is installed on one side surface of the bottom box 10, and the first limiting plate 8 is in contact with the side surface of the weighing platform 1. A second limiting plate 15 is installed on the side surface of the bottom box 10 away from the first limiting plate 8, and the second limiting plate 15 is in contact with the side surface of the weighing platform 1. The first limiting plate 8 and the second limiting plate 15 work together to prevent the weighing platform 1 and the bottom box 10 from sliding laterally.

[0020] A sewage discharge valve 9 penetrating the first limiting plate 8 is installed on the surface of the bottom box 10 facing the first limiting plate 8. When dust enters the bottom of the weighing platform 1, the dust falls into the moisture in the bottom box 10 through the holes in the perforated plate 11, thus achieving the purpose of centralized dust collection, preventing the dust from accumulating at the bottom of the weighing platform 1 and gradually increasing, which affects the accuracy of the pressure sensor 14 detection. The dust falling into the bottom box 10 is wetted by the moisture, achieving the purpose of preventing the dust from rising again. After opening the sewage discharge valve 9, the moisture mixed with dust is discharged through the sewage discharge valve 9, realizing convenient cleaning of the dust accumulated under the weighing platform 1.

[0021] A horizontally arranged air supply pipe 13 is provided at the lower position inside the bottom box 10. A plurality of air outlet holes 19 are evenly opened at the lower position of the outer surface of the air supply pipe 13. One end of the air supply pipe 13 penetrates the second limiting plate 15 and is connected to the air outlet end of an air pump 16. Before opening the sewage discharge valve 9, the circuit of the air pump 16 is connected, and the air pump 16 works to transport air into the air supply pipe 13. The air in the air supply pipe 13 is discharged into the moisture in the bottom box 10 through the air outlet holes 19, playing a role in stirring the moisture.

[0022] A number of guide rods 2 are evenly installed on the lower surface of the weighing platform 1. A number of guide holes that cooperate with the guide rods 2 are provided on the perforated plate 11. The lower ends of the guide rods 2 penetrate through the guide holes and extend to the upper part inside the bottom box 10. The design of the guide rods 2 and the guide holes further improves the stability of the relative position between the weighing platform 1 and the bottom box 10.

[0023] On the upper part of the side of the vertical plate 3 facing away from the weighing platform 1, a support plate 7 is installed. On the upper surface of the support plate 7, a vertically arranged internal thread cylinder 6 is installed. A threaded column 5 is threadedly connected inside the internal thread cylinder 6. On the outer surface of the upper end of the threaded column 5, a handle 4 is installed. By rotating the threaded column 5 with the handle 4, the height of the structure jointly formed by the threaded column 5 and the internal thread cylinder 6 is realized, so that the height of the threaded column 5 is higher than the height of the vehicle chassis, preventing the wheels from riding on the vertical plate 3.

[0024] On the upper part of the side of the bottom box 10 facing the second limiting plate 15, a water adding pipe 17 is installed. One end of the water adding pipe 17 away from the bottom box 10 penetrates through the second limiting plate 15 and bends upward. A cap 18 is sleeved on the outer surface of the end of the water adding pipe 17 away from the bottom box 10. After the cap 18 is opened, it is convenient to add water into the bottom box 10 through the water adding pipe 17.

[0025] On the upper part of the side of the vertical plate 3 facing the weighing platform 1, an inclined surface is processed. The design of the inclined surface plays a role in protecting the tires.
