[0015] Figure 2 Fig. 2 is a structural schematic view of the bottom plate of the sealing protection device. DETAILED DESCRIPTION

[0016] The sealing protection device for the high-speed rail line tuning equipment provided by the utility model will be further described in detail in combination with the drawings. Obviously, the described embodiments are only a part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.

[0017] In the description of this utility model, unless otherwise stated, the orientation or positional relationship indicated in the terminology is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0018] It should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "set / equipped" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] like Figure 1 As shown, the sealing and protective device structure of the high-speed rail tuning equipment includes a base plate 1 and a cover 2 that is fastened to it. The inner side of the cover 2 is provided with a groove 21, and a sealing gasket 22 is laid in the groove 21. The edge of the base plate 1 is provided with a protrusion 31, which engages with the groove 21 to position and press the sealing gasket 22. Several vibration damping mechanisms are provided between the protrusion 31 and the groove 21. The vibration damping mechanism includes a pressure strip 31 that cooperates with the sealing gasket 22. The pressure strip 31 is connected to at least one slide rod 32. The slide rod 32 passes through the bottom of the groove 21 and a pre-tensioning spring 33 is provided between its end and the groove 21.

[0020] Its working principle is as follows: The base plate 1 is arranged on both sides of the high-speed rail track according to the preset spacing. The tuning device (such as ZPW2000) is inserted on the surface of the base plate 1, and then the cover 2 is fastened. Since the edge of the cover 2 is provided with a groove 21 and the inside is lined with a sealing gasket 22, after it is engaged and pressed with the protrusion 31 on the edge of the base plate 1, it not only ensures stable positioning but also achieves tight sealing. At the same time, a vibration damping mechanism is installed between the protrusion 31 and the groove 21, which consists of a pressure strip 31 and a slide rod 32. The pressure strip 31 cooperates with the sealing gasket 22, and the slide rod 32 passes through the bottom of the groove 21, and a pre-tightening spring 33 is provided between its end and the groove 21. That is, the pre-tightening spring 33 always applies force to the slide rod 32, so that the sealing gasket 22 and the protrusion 31 are tightly attached. When subjected to high-speed impact, the vibration will not cause the seal to fail, nor will there be problems such as misalignment or detachment at the engagement joint. This achieves the effect of tight sealing connection of the protective device, dustproof, waterproof and cold-resistant.

[0021] It should be noted that the preload spring 33 is initially in a stretched state, with one end connected to the end of the slide bar 32 and the other end abutting against the groove 21, thereby achieving a real-time pressing effect on the slide bar 32.

[0022] In the sealing and protective device structure that constitutes the aforementioned tuning equipment along the high-speed railway line

[0023] —As a preferred embodiment, the pressing surfaces of the protruding strip 31 and the pressure strip 31 are conical, and the sealing gasket 22 located between them is composed of elastic colloid and water-swellable rubber edges placed on both sides. The conical contact pressing area is large, and the sealing gasket 22 has a wider sealing area. At the same time, the water-swellable rubber on both sides of the sealing gasket 22 enhances the blocking effect against rainwater, making the protective cover more tightly sealed and providing good dustproof and windproof performance.

[0024] — Preferably, the base plate 1 and the cover 2 are provided with corresponding ear plates 41 along their edges. The ear plates 41 are connected and positioned by through bolts 42. The ear plates 41 are preferably symmetrically arranged on both sides of the protective cover. The connection and positioning degree are further improved by bolts 42. The four corners of the bottom of the base plate 1 are provided with positioning flanges 51. The inner surface of the base plate 1 is provided with a detachable positioning bracket 52 for inserting circuit boards or installing electrical components. The bottom of the positioning bracket 52 can be connected to the base plate 1 by bolts for easy installation and disassembly.

[0025] —In one embodiment, the cover 2 and the base plate 1 are connected by a hinge structure 61 of one flange. The other flange of the cover 2 is provided with a traction handle 62. The traction handle 62 facilitates quick opening and closing of the cover 2. The end of the pivot 71 of the traction handle 62 is provided with a slide 72. The other flange of the base plate 1 is provided with a fan-shaped groove 73 that cooperates with the slide 72. The fan-shaped groove 73 has an opening that matches the shape of the slide. That is, after the cover 2 is closed by the hinge structure 61 of one flange, it overlaps with the other flange. The pivot 71 of the traction handle 62 and the slide 72 at the end enter the fan-shaped groove 73 through the opening. At this time, rotating the traction handle 62 causes the slide 72 to rotate horizontally and form a limit with the fan-shaped groove 73, thus realizing the locking connection.

[0026] --like Figure 2 As shown, the base plate 1 is further provided with several cable through holes 81, and the cable through holes 81 are provided with sealing sleeves 82. The sealing sleeves 82 are tapered tubes made of elastic rubber. The bottom edge of the tapered tube is fixed to the edge of the cable through hole by bonding, welding or bolting. That is, the through holes where the power line or communication line enters the protective cover can also be sealed to prevent wind, sand, dust and water from entering. If the cable through hole 81 is a rectangular hole, the sealing sleeve is a square tube that matches it, with one end closed and a through hole opened on its end face.

[0027] — Preferably, the base plate 1 and the cover 2 are both molded by SMC 91. High-density fiberglass has the advantages of high mechanical strength, light weight, corrosion resistance, long service life and good sealing performance. It has strong impact resistance and weather resistance, and its service life is significantly extended. At the same time, the inner surfaces of the base plate 1 and the cover 2 are provided with a metal shielding coating 92 to further avoid electromagnetic interference and effectively ensure the normal operation of the electrical system inside the protective cover.

[0028] The above-described embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit the implementation conditions of the present application. Therefore, any other modifications or equivalent replacements to the technical solutions of the present application, such as modification of the structure size, internal structure, etc., as long as they do not deviate from the spirit and scope of the technical solutions of the present application, should be covered in the scope of the claims of the present application.
