Description

Technical Field

[0001] The utility model relates to the technical field of electronic truck scales, in particular to a waterproof mechanism for explosion-proof weighing. Background Technique

[0002] In the field of electronic truck scales, explosion-proof weighing systems usually need to have waterproof functions to adapt to various harsh environments, especially in flammable and explosive environments such as the chemical, petroleum, and natural gas industries. The waterproof mechanism design of explosion-proof weighing systems is to ensure that under the influence of rain or other liquids, the electronic components and sensors of the weighing system can work normally and prevent electrical failures or performance degradation caused by moisture intrusion.

[0003] Most of the existing waterproof mechanisms for explosion-proof weighing use sealing rings for waterproofing in the application of electronic truck scales. Especially in rainy weather, rainwater falls on the surface of the electronic truck scale and cannot be effectively drained, resulting in rainwater penetrating into the interior of the electronic truck scale, which is likely to cause short circuits in the electrical components inside the electronic truck scale. Secondly, the interior of the electronic truck scale does not have explosion-proof functions. When an open fire occurs in the electrical components inside the electronic truck scale, if effective fire extinguishing cannot be achieved, there may be an explosion risk. Therefore, a waterproof mechanism for explosion-proof weighing is proposed.

[0004] At present, the waterproof mechanism for explosion-proof weighing has the following disadvantages in the market: 1. When in use, it is not easy to drain the rainwater falling on the surface of the electronic truck scale to prevent rainwater from penetrating into the equipment interior and causing short circuits in the internal electrical components; 2. When a fire occurs, it is not easy to extinguish the open fire inside to prevent the fire from getting out of control and causing an explosion risk.

[0005] Therefore, it is very necessary to invent a waterproof mechanism for explosion-proof weighing to solve the above problems. Content of the Utility Model

[0016] (III) Beneficial effects

[0018] 1. The explosion-proof weighing waterproof mechanism, through the settings of the waterproof mechanism and the drainage ports, in rainy weather, when rain falls on the surface of the electronic truck scale, the rainwater flows along several drainage ports set on the surface of the electronic truck scale into the internal water collection tanks on both sides, and then two drainage pipes set inside the water collection tanks transport the rainwater to a position far away from the electronic truck scale, which can effectively prevent rainwater from accumulating on the surface of the electronic truck scale, causing the rainwater to penetrate into the interior of the electronic truck scale, and further resulting in a short circuit of the internal electrical components and affecting the normal use of the equipment.

At this time, the fire extinguishing agent is quickly ejected under the action of the driving gas, thereby achieving fire extinguishing and preventing an explosion due to excessive fire.
