Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electromagnetic compatibility testing, in particular to an exhaust gas emission device for shielding gas on a steel plate from passing through the wall. Background Art
[0002] Currently, the need for whole-vehicle or engine testing is increasing in the field of electromagnetic compatibility (EMC) testing. In actual testing, the vehicle or engine must be tested while in operation, which means that exhaust fumes are constantly generated during testing. Since the EMC chamber is a relatively closed environment during testing, exhaust fumes are continuously generated during vehicle or engine testing, and these fumes need to be promptly discharged outdoors. Therefore, a device is needed to exhaust the exhaust fumes from the chamber without compromising the shielding effectiveness of the chamber. The current industry approach is to install a narrow hollow pipe on a shielding steel plate to discharge the exhaust fumes. This method can achieve the desired exhaust fumes discharge effect, but it compromises the shielding effectiveness of the chamber and no longer meets the required requirements. Therefore, the industry needs a special device that can achieve the desired exhaust fumes discharge effect without compromising the shielding effectiveness of the chamber. Utility Model Content
[0003] In order to solve the problems raised in the above-mentioned background technology, the purpose of the present utility model is to provide an exhaust gas emission device for shielding gas passing through the wall on the steel plate, which has the advantages of being easy to install on the shielding steel plate and not affecting the shielding efficiency of the darkroom. It solves the problem that the current treatment method in the industry is to install a narrow and long hollow pipe on the shielding steel plate to discharge exhaust gas. This method can achieve the emission effect, but destroys the shielding efficiency of the darkroom and no longer meets the use requirements.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an exhaust gas emission device for shielding gas from passing through the wall on a steel plate, comprising an exhaust gas emission device body, the front side of the exhaust gas emission device body being connected to a pipe, the front end of the pipe being connected to a flange, and the interior of the pipe being connected to a honeycomb core.
[0005] As a preferred embodiment of the present invention, a mounting hole is opened on the front side of the flange, and there are twelve mounting holes arranged and distributed at equal distances, and the diameter of the mounting holes is 12 mm.
[0006] As a preferred embodiment of the present invention, the pore diameter of the honeycomb core is set to 4 mm.
[0007] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0008] 1. The utility model provides a honeycomb core to ensure the stability of exhaust emissions without affecting the shielding effectiveness. It solves the problem that the current industry approach is to install a narrow hollow pipe on the shielding steel plate to discharge exhaust gas. This approach can achieve the effect of emission, but destroys the shielding effectiveness of the darkroom and no longer meets the use requirements. It achieves the effect of being easy to install on the shielding steel plate without affecting the shielding effectiveness of the darkroom.
[0009] 2. The utility model sets twelve mounting holes with a diameter of 12 mm, so that the mounting holes correspond to the positions of the openings on the shielding steel plate. The device can be conveniently fixed to the shielding steel plate by self-locking screws, thereby improving the convenience of use.
[0010] 3. The utility model sets the aperture of the honeycomb core to 4 mm to ensure smooth passage of exhaust gas. At the same time, these through holes with very small apertures will not affect the shielding performance of the darkroom. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0016] like Figures 1 to 3 As shown, the utility model provides an exhaust gas emission device for shielding gas from passing through the wall on a steel plate, comprising an exhaust gas emission device body 1, the front side of the exhaust gas emission device body 1 is connected to a pipe 2, the front end of the pipe 2 is connected to a flange 3, and the interior of the pipe 2 is connected to a honeycomb core 4.
[0017] refer to Figure 1 The front side of the flange 3 is provided with mounting holes. There are twelve mounting holes and they are evenly distributed. The diameter of the mounting holes is 12 mm.
[0018] As a technical optimization solution of the present invention, by setting mounting holes, twelve mounting holes with an aperture of 12 mm are made to correspond to the positions of the openings on the shielding steel plate. The device can be conveniently fixed to the shielding steel plate through self-locking screws, thereby improving the convenience of use.
[0019] refer to Figure 1 , the aperture of the honeycomb core 4 is set to 4 mm.
[0020] As a technical optimization solution of the present invention, the aperture of the honeycomb core 4 is set to 4 mm to ensure smooth passage of exhaust gas. At the same time, these through holes with very small apertures will not affect the shielding performance of the darkroom.
[0021] The working principle and usage process of the present invention are as follows: when in use, the exhaust gas emission device body 1 is connected to the pipe 2 and the flange 3, and then twelve mounting holes with an aperture of 12 mm are used to make the mounting holes correspond to the positions of the openings on the shielding steel plate. The device can be conveniently fixed to the shielding steel plate through self-locking screws. After installation, there are many holes with a diameter of 4 mm on the honeycomb core 4 of the exhaust gas emission device body 1. The diameter of these holes is small enough and the thickness is wide enough to ensure that the exhaust gas passes through smoothly, which will not affect the shielding effectiveness or the passage of the exhaust gas, thereby achieving the effect of being easy to install on the shielding steel plate and not affecting the shielding effectiveness of the darkroom.
[0022] To sum up: this exhaust gas emission device for shielding gas passing through the wall on the steel plate, by setting the honeycomb core 4, ensures the stability of the exhaust gas emission and does not affect the shielding effectiveness, and solves the current industry treatment method of installing a narrow and long hollow pipe on the shielding steel plate to discharge the exhaust gas. This method can achieve the emission effect, but destroys the shielding effectiveness of the darkroom and no longer meets the use requirements.
