Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A schematic diagram of a preferred embodiment of an electrical device for undercarriage inspection of rail transit vehicles provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the sealing mechanism. Figure 3 for Figure 1 The diagram shows the structure of the observation baffle. Figure 4 for Figure 1 The diagram shows the structure of the storage baffle. Figure 5 for Figure 1 The diagram shows the structure of the sealing baffle. An electrical device for inspecting the undercarriage of a rail transit vehicle includes: an electrical base 1, a sealing baffle 2, and a storage baffle 3. The sealing baffle 2 is rotatably mounted on the side of the electrical base 1 for structural sealing of the electrical base 1. The storage baffle 3 is installed on the inner wall of the bottom of the electrical base 1. Sealing mechanisms 6 are installed on the inner walls at both ends of the electrical base 1 for sealing the sealing baffle 2. Fastening mechanisms 7 are installed and connected to the sides of both the electrical base 1 and the sealing baffle 2 for positional installation of the sealing baffle 2. Storage mechanisms 8 are installed at both ends of the storage baffle 3, and the storage mechanisms 8, in conjunction with the fastening mechanisms 7, can be used to store the sealing baffle 2.

[0022] The electrical base 1 is equipped with a first fastener 4 on its side end. The first fastener 4 includes a fastening plate 41, a first fixing member 42, and a second fixing member 43. The first fixing member 42 is installed on the inner wall of the side end of the fastening plate 41 to stabilize the position of the fastening plate 41. The second fixing member 43 is movably installed on the inner wall of the bottom of the fastening plate 41 to connect the position of the fastening plate 41.

[0023] During use, the electrical base 1 can be fixed in position by fastening plates 41 at both ends of the electrical base 1 to reduce the positional shaking of the electrical base 1 during use.

[0024] Among them, the first fastener 4 includes, but is not limited to, threaded fasteners, snap fasteners, and riveting fasteners;

[0025] In this embodiment, the first fastener 4 is preferably threaded, with a bolt passing through the hole of the connected parts and then tightened with a nut. The friction and preload of the threads are used to fix the components together. This method is simple in structure, reliable in connection, convenient in assembly and disassembly, and the tightening force can be adjusted as needed.

[0026] Both the electrical substrate 1 and the inner wall of the sealing baffle 2 are equipped with observation baffles 5, which can be used to observe the use of the electrical substrate 1 and make timely position adjustments.

[0027] The observation baffle 5 installed on the inner wall of the workpiece allows the staff to observe the workpiece without disassembling it, so as to make timely adjustments and provide convenience for use.

[0028] Among them, the observation baffle 5 includes, but is not limited to, a metal observation plate, a plastic observation plate, and a composite material observation plate;

[0029] In this embodiment, the observation baffle 5 is preferably a composite material observation baffle. By using a composite material baffle, the good corrosion resistance and insulation of the baffle can be improved. It can be customized according to specific usage requirements and environment, and is suitable for some special occasions with complex performance requirements.

[0030] The sealing mechanism 6 includes a mounting groove 61 and a first elastic element 62. The mounting groove 61 is formed on the inner wall of both ends of the electrical substrate 1. The first elastic element 62 is symmetrically arranged inside the mounting groove 61. A pressing plate 63 is installed on the side end of the first elastic element 62. The pressing plate 63 cooperates with the first elastic element 62 and can be used for the position movement of the pressing plate 63 and for the baffle sealing of the sealing baffle 2. A sealing gasket layer 64 is installed on the side end of the pressing plate 63.

[0031] When the side sealing baffle 2 comes into contact with the sealing mechanism 6, the first elastic element 62 provided on the side will tightly press the extrusion plate 63 to the side position. Subsequently, the sealing gasket layer 64 on the inner wall of the extrusion plate 63 will reduce the gap between the sealing baffles 2, thereby improving the sealing effect of the device baffles.

[0032] Among them, the sealing mechanism 6 includes, but is not limited to, rubber seals, sealant, and mechanical seals;

[0033] In this embodiment, the sealing mechanism 6 is preferably a rubber seal, which, through the use of the sealing gasket 64, has good elasticity and sealing performance, and can achieve reliable sealing in a small installation space. It can be used for both static and dynamic sealing.

[0034] The fastening mechanism 7 includes a fastening groove 711, a mounting groove 72, and a fastening block 75. The fastening groove 71 is formed on the inner walls of both ends of the electrical substrate 1, and the mounting groove 72 is formed on the inner walls of both ends of the receiving baffle 3. Fastening rods 73 are respectively installed on the inner walls of the electrical substrate 1 and the mounting groove 72. A rotating handle 74 is installed on the side end of the fastening rod 73. The fastening block 75 is respectively installed on the inner walls of the sealing baffle 2 and the fastening rod 73. The cooperation between the fastening block 75 and the fastening rod 73 can be used for secondary sealing treatment of the sealing baffle 2.

[0035] When the sealing baffle 2 is rotated, the top fastening block 75 will be threaded onto the inner wall of the fastening rod 73. Then, by rotating the fastening rods 73 at both ends, the position of the fastening block 75 is driven to move. During the position movement, the fastening block 75 will once again squeeze the sealing baffle 2 to perform a secondary tightening and sealing, thereby further reducing the adverse effects of external factors.

[0036] Among them, the fastening mechanism 7 includes, but is not limited to, welding fastening, snap fastening, and nut fastening;

[0037] In this embodiment, the fastening mechanism 7 preferably uses a nut for fastening. By rotating the nut, it moves forward or backward along the thread of the bolt, thereby tightly connecting two or more components together. This fastening method is simple in structure, low in cost, and easy to use.

[0038] The storage mechanism 8 includes a sliding frame 81 and a sliding rod 83. The sliding frame 81 is respectively disposed on the inner wall of both ends of the storage baffle 3. The sliding frame 81 has a sliding groove 82. The sliding rod 83 is installed on the inner wall of both ends of the sealing baffle 2. The sliding rod 83 cooperates with the fastening mechanism 7 and can be used for baffle storage of the sealing baffle 2.

[0039] When storing the baffle, firstly, rotate the sealing baffle 2 from vertical to horizontal, and then move the entire sealing baffle 2 to the side. At this time, the sliding rods 83 at both ends will slide along the direction of the sliding groove 82. With continuous position movement, the entire sealing baffle 2 will be stored by the storage baffle 3 at the bottom, so as to facilitate the staff to repair and replace the internal structure of the device, thereby improving the practicality of the device.

[0040] Among them, the storage mechanisms 8 include, but are not limited to, general-purpose storage and special-purpose storage;

[0041] In this embodiment, the storage mechanism 8 is preferably a dedicated type of storage, designed with specific size and shape of the baffle so that the baffle will not obstruct or hinder the view.

[0042] The working principle of the electrical device for undercarriage inspection of rail transit vehicles provided by this utility model is as follows:

[0043] In daily use, the electrical device is first installed in a convenient position on the entire electrical base 1. When sealing the entire device, the side sealing baffle 2 can be rotated and limited in position. At this time, a sealing mechanism 6 is provided on the electrical base 1. The rotating sealing baffle 2 will first contact the sealing mechanism 6 to pre-seal the gap between the sealing baffles 2. Subsequently, fastening mechanisms 7 are provided at both ends of the sealing baffle 2. By rotating the fastening mechanism 7, the entire sealing baffle 2 can be tightened and squeezed a second time to improve the tight seal between the sealing baffle 2 and the sealing mechanism 6, thereby reducing the adverse effects caused by external factors. At the same time, the storage mechanism 8 provided at the bottom can conveniently store the sealing baffle 2 in a convenient position for the staff to carry out structural maintenance and replacement later.

[0044] Compared with related technologies, the electrical device for bottom inspection of rail transit vehicles provided by this utility model has the following advantages:

[0045] During daily use, the internal sealing strips of electrical devices are prone to aging. To improve the sealing effect, the sealing mechanism 6 and the fastening mechanism 7 work together to perform a secondary tightening of the internal sealing strips, reducing the intrusion of rainwater and dust into the enclosure and thus minimizing the impact on the sensor's lifespan. Furthermore, the storage mechanism 8 at the bottom allows for convenient and flexible storage of the device's baffles, facilitating maintenance and replacement of the internal structure.
