[0002] A reversing valve protective cover is a protective device mainly used to protect products such as electro-hydraulic control reversing valves, solenoid valve drivers, and electromagnetic pilot valves, and to prevent product damage or failure caused by the impact of falling objects during underground work. When in use, the reversing valve protective cover is fixed on the surface of the main valve body. The side panel protects the electrical connector, and the upper panel protects other products such as solenoid valve drivers and electromagnetic pilot valves. The working principle and structure of the reversing valve protective cover are relatively simple. However, due to the large usage amount and high working reliability, higher requirements are put forward for the structural design and compatibility.

Detailed implementation manners

[0025] The following further describes the present utility model with reference to the drawings and specific embodiments:

[0026] As Figures 1 to 7 shown, an adjustable reversing valve protective cover provided by the present utility model includes a support plate 1, an upper protective cover 2, a sliding protective cover 4, a side protective cover 7, a bottom plate 9 and a fixed mounting seat 10. The support plate 1 is respectively connected to the upper protective cover 2, the side protective cover 7 and the bottom plate 9. The upper protective cover 2, the side protective cover 7 and the bottom plate 9 are respectively slidably connected to the sliding protective cover 4. The sliding protective cover 4 can slide along the upper protective cover 2, the side protective cover 7 and the bottom plate 9. The bottom of the bottom plate 9 is fixedly connected to the fixed mounting seat 10.

[0027] The support plate 1 is a plate-shaped structure bent into a "U" shape. The connection manner of the support plate 1 to the upper protective cover 2, the side protective cover 7 and the bottom plate 9 is an existing connection technology, such as welding, etc.

[0028] The upper protective cover 2 is in the shape of an "L"-shaped sheet structure. A first sliding limit bolt 3 is installed on the upper protective cover 2, and the first sliding limit bolt 3 is slidably connected to the sliding protective cover 4. In this embodiment, both the side protective cover 7 and the upper protective cover 2 are in an L-shaped structure.

[0029] The upper protective cover 2 is provided with an upper protective cover through slot 21, and the upper protective cover through slot 21 is in the shape of an oblong hole structure. The end of the upper protective cover 2 is provided with an upper protective cover through hole 22. During actual use, the upper protective cover through hole 22 is used to pass through existing related power cables and other devices. Compared with a long strip structure, the L-shaped structure of the upper protective cover 2 has better seismic resistance. This is because the L-shaped structure can better disperse and absorb external impact forces, reducing structural damage caused by external impacts. In addition, during the design and manufacturing process, the L-shaped structure can provide more design flexibility, facilitating the realization of complex design requirements and meeting specific functional requirements. The upper protective cover 2 has good seismic resistance, and the L-shaped structure performs excellently in terms of seismic resistance. Especially when there are no special requirements for setting joints, this structural form can provide better seismic resistance.

[0030] The sliding protective cover 4 includes a first sliding protective cover plate 41, a second sliding protective cover plate 42, a third sliding protective cover plate 43, and a sliding protective cover connecting block 44. The first sliding protective cover plate 41, the second sliding protective cover plate 42, and the third sliding protective cover plate 43 are arranged parallel to each other. The sliding protective cover connecting block 44 is in the shape of a "convex" block structure. The end of the second sliding protective cover plate 42 is fixedly connected to the protruding top of the sliding protective cover connecting block 44 to form an integral structure. The first sliding protective cover plate 41 and the third sliding protective cover plate 43 are respectively fixedly connected to the bottom of the sliding protective cover connecting block 44 to form an integral structure. The first sliding protective cover plate 41 is in a plate structure. The second sliding protective cover plate 42 is provided with a second sliding protective cover plate through hole 421, and the second sliding protective cover plate through hole 421 is in the shape of an oblong hole structure. The first sliding protective cover plate 41 and the third sliding protective cover plate 43 have the same structure and are arranged in parallel.

[0031] A fixing screw 6 is welded on the second sliding protective cover plate 42. The other end of the fixing screw 6 passes through the side protective cover 7 and is sleeved with a wing nut 5, and the wing nut 5 can tightly connect the side protective cover 7 and the second sliding protective cover plate 42.

[0032] The first sliding limit bolt 3 passes through the upper protective cover through slot 21 and the second sliding protective cover plate through hole 421 to connect the upper protective cover 2 and the sliding protective cover 4.

[0033] The wing nut 5 and the fixing screw 6 are in a threaded fit connection, and the wing nut 5 can rotate along the fixing screw 6.

[0034] The side protective cover 7 is provided with a side protective cover through-hole 71. The side protective cover through-hole 71 is in the shape of a waist-shaped hole, and the fixing screw 6 passes through the side protective cover through-hole 71. The side protective cover through-hole 71 is in the structure of a limiting groove.

[0035] A reinforcing rib 8 is welded between the bottom plate 9 and the fixed mounting seat 10, and the reinforcing rib 8 is fixedly connected to the bottom plate 9 and the fixed mounting seat 10 respectively.

[0036] The bottom plate 9 is arranged in parallel with the upper protective cover 2. A second sliding limit bolt 11 is installed on the bottom plate 9, and the second sliding limit bolt 11 is slidably connected to the sliding protective cover 4. Specifically: The second sliding limit bolt 11 passes through the corresponding waist-shaped hole on the third plate 43 of the sliding protective cover and is connected to the sliding protective cover 4. The connection mode of the second sliding limit bolt 11 and the third plate 43 of the sliding protective cover is the same as the connection mode of the first sliding limit bolt 3 and the first plate 41 of the sliding protective cover.

[0037] The upper protective cover 2, the side protective cover 7 and the sliding protective cover 4 are all made of 304 stainless steel or alloy steel or engineering plastic. The support plate 1 is in a U-shaped structure.

[0038] In this embodiment, the end cross-sections of the limiting grooves formed on the upper protective cover 2, the side protective cover 7 and the sliding protective cover 4 are all in a semi-circular structure.

[0039] Specifically, the side of the support plate 1 limits the minimum displacement of the sliding protective cover 4. Its working principle is as follows:

[0040] In the utility model, the upper protective cover 2 and the sliding protective cover 4 are connected by the first sliding limit bolt 3. The first sliding limit bolt 3 passes through the limiting grooves on the upper surface of the upper protective cover 2 and the sliding protective cover 4. The fixing screw 6 is welded on the outer shell of the sliding protective cover 4. The fixing screw 6 passes through the limiting groove on the side protective cover 7. The protection range of the protective cover is adjusted by changing the position of the sliding protective cover 4, and the final positioning of the sliding protective cover 7 is realized by the connection mode of the butterfly fastening nut 5 and the fixing screw 6 in a bolt connection. The bottom plate 9 and the fixed mounting seat 10 are welded and connected with the addition of the reinforcing rib 8.

[0041] During actual operation, first, the upper protective cover 2, the side protective cover 7 and the bottom plate 9 are respectively fixedly connected to the support plate 1. Secondly, the fixing screw 6 is welded on the side of the sliding protective cover 4 and passes through the limiting groove of the side protective cover 7.
