The length of the signal conditioner top cover 3 is greater than the length of the signal conditioner housing 1, and the width of the signal conditioner top cover 3 is the same as that of the signal conditioner housing 1. Heat dissipation grooves 4 are respectively opened at the diagonal positions inside the signal conditioner top cover 3, and dust-proof nets 5 are arranged inside the heat dissipation grooves 4. Through grooves 6 are respectively opened at the front and back of the right side inside the signal conditioner top cover 3. A connecting shaft 7 is fixedly connected to the position of the signal conditioner housing 1 corresponding to the through grooves 6, and a limiting plate 8 is rotatably connected to the connecting shaft 7 and pressed against the top of the signal conditioner top cover 3. A rubber pad is provided at the bottom of the limiting plate 8, and the rubber pad is attached to the top of the signal conditioner top cover 3.

[0028] By flipping the signal conditioner top cover 3 to fit against the bottom of the signal conditioner housing 1, at this time the connecting shaft 7 is inserted into the through groove 6, and the limiting plate 8 is located on the top of the signal conditioner top cover 3. Then rotate the limiting plate 8 to fit against the top of the signal conditioner top cover 3. At this time, the installation of the signal conditioner top cover 3 is completed, and it is also relatively convenient to disassemble and open the signal conditioner top cover 3.

[0029] Reference Figure 1 and 3 As shown in the figure, a signal conditioner 9 is arranged inside the signal conditioner housing 1. A limiting groove 10 is opened above the signal conditioner top cover 3, and a protection plate 11 is movably inserted into the limiting groove 10. A baffle 12 is fixedly connected to the top of the protection plate 11, and the length and width of the baffle 12 are greater than the length and width of the limiting groove 10. A first fastening bolt 13 is threadedly connected to the right side inside the signal conditioner top cover 3, and the first fastening bolt 13 presses against the protection plate 11.

[0030] The positions of the protection plate 11 and the baffle 12 can be adjusted through the first fastening bolt 13. When the protection plate 11 and the baffle 12 are adjusted downward, at this time the protection plate 11 can seal and protect the interface of the signal conditioner 9, so that the interface of the signal conditioner 9 is not easily damaged. When the protection plate 11 and the baffle 12 are adjusted upward, at this time the interface of the signal conditioner 9 can be exposed to the outside for use.

[0031] Reference Figure 1 and 3 As shown in the figure, a storage groove 14 and an operation groove 15 are opened at the lower part of the right side inside the signal conditioner housing 1.

When the wire support plate 16 is adjusted upward, the wire support plate 16 can support the wire connected to the interface of the signal conditioner 9 at this time, preventing the wire from being bent and damaged. When the wire support plate 16 is adjusted downward, the wire support plate 16 can be better stored in the storage groove 14 at this time.

[0033] Advantages of this application: It is convenient to better install the signal conditioner top cover 3, making it more convenient to open the signal conditioner top cover 3, so that better maintenance can be carried out on the signal conditioner 9. At the same time, the interface of the signal conditioner 9 can be sealed and protected by the protection plate 11, making the interface of the signal conditioner 9 not easily damaged. And the wire at the interface of the signal conditioner 9 can be supported by the wire support plate 16, preventing the wire from being bent and damaged.

[0034] Working principle: By flipping the signal conditioner top cover 3 and fitting it to the bottom of the signal conditioner housing 1, the connecting shaft 7 is inserted into the through groove 6 at this time, and the limiting plate 8 is located at the top of the signal conditioner top cover 3. Then rotate the limiting plate 8 and fit it to the top of the signal conditioner top cover 3. At this time, the installation of the signal conditioner top cover 3 is completed, and it is also relatively convenient to disassemble and open the signal conditioner top cover 3.

[0035] The position of the protection plate 11 and the baffle 12 can be adjusted by the fastening bolt one 13. When the protection plate 11 and the baffle 12 are adjusted downward, the protection plate 11 can seal and protect the interface of the signal conditioner 9 at this time, making the interface of the signal conditioner 9 not easily damaged. When the protection plate 11 and the baffle 12 are adjusted upward, the interface of the signal conditioner 9 can be exposed to the outside for use at this time.

[0036] By adjusting the fastening bolt two 17, the position of the wire support plate 16 can be adjusted. When the wire support plate 16 is adjusted upward, the wire support plate 16 can support the wire connected to the interface of the signal conditioner 9 at this time, preventing the wire from being bent and damaged. When the wire support plate 16 is adjusted downward, the wire support plate 16 can be better stored in the storage groove 14 at this time.
