Of course, after the left and right plastic suction cases are subjected to trimming processing, the front and rear sides of the side walls of the left and right cases may be completely cut off or partially cut off by mechanical cutting processing, leaving open spaces for mounting the front cover 104 and the rear cover 105, as needed. As shown in fig. 9 and 15, the left and right housing front openings 1015 and 1025 match the shape of the front cover 104, leaving an open space for mounting the front cover 104; the left housing rear opening 1014 and the right housing rear opening 1024 match the shape of the rear cover 105, leaving open space for mounting the rear cover 105. Of course, in order to install the separate chassis, the bottom surfaces of the left and right housing side walls may be completely cut or partially cut by machining, and only the top surfaces of the left and right housing side walls may be left. In order to fully utilize the blank material of the plastic suction shell, the invention requires that at least one of the top surface, the front surface, the rear surface and the bottom surface forming the side walls of the left and right shells is not completely cut off, and the surface and the closed ends of the left and right shells form an integral structure, namely, the side walls of the plastic suction shells are at least partially reserved. Specifically, the left housing closed end 1011 forms an integral structure with at least one of the four faces of the left housing side wall top face 10131, the front face 10132, the rear face 10133 and the bottom face 10134, and the right housing closed end 1021 forms an integral structure with at least one of the four faces of the right housing side wall top face 10231, the front face 10232, the rear face 10233 and the bottom face 10234. Further, as shown in fig. 3 and 4, the side wall integrally formed with the closed end 1011 of the left casing and the side wall integrally formed with the closed end 1021 of the right casing are spliced and connected by the connecting member 103, so that under the condition that the total width W of the casing of the power generation equipment is constant, the left casing side wall width W1 and the right casing side wall width W1 are wider, and the connecting of the left casing and the right casing at the side wall which is not cut off can maximally utilize the casing side wall width W1, so that the width W2 of the connecting member 103 is smaller, which is beneficial to reducing the cost of the connecting member 103. As shown in fig. 14, the sidewall widths W1 of the left case 101 and the right case 102 may be different, and in order to utilize the suction case sidewall as much as possible, the present invention requires: the width W1 of the left housing 101 or the right housing 102 with the larger side wall width should be at least larger than half the width W2 of the connecting member 103, that is, the size relationship between the left and right housing side wall widths W1 and the width W2 of the connecting member 103 is: . In practice, the best design should be: w1> W2, namely: the left housing 101 or right housing 102 sidewall width W1 should be greater than the connector 103 width W2. Note that: since the side walls of the left and right cases may be partially cut, for example, the front opening 1015 and the rear opening 1014 of the left case, the side wall width W1 should be the width before the side wall is cut, and also the maximum width on the side wall after the side wall is cut.

It should be noted that after the left and right shells are molded by suction to obtain a shell blank, the open end of the shell needs to be trimmed, and an open end edge 10121 is formed at the end of the side wall of the open end of the left shell after trimming, as shown in fig. 11. Because of the technical characteristics of the trimming process, the open end edges 10121 of the left shell circumference are located in the same plane, namely, the end edges of the four surfaces of the top surface 10131, the front surface 10132, the rear surface 10133 and the bottom surface 10134 of the left shell side wall are located in the same plane. In this way, even if one or more of the left housing side wall top surface 10131, front surface 10132, rear surface 10133 and bottom surface 10134 are completely cut away, as long as one side wall surface remains not completely cut away, the position and size of this side wall surface area before cutting away can be inferred from the position of this side wall surface end and the shape of the left housing closed end 1011. Note that: the invention only requires that the footing 3 is arranged in the bottom surface area of the side wall of the shell, and is irrelevant to whether the bottom surface of the side wall of the plastic suction shell has a physical structure or not, and the footing 3 is not necessarily directly connected with the bottom surface of the side wall of the shell. Therefore, even if the bottom surface 10134 of the side wall of the left housing is partially or completely cut off by machining, as long as a side wall surface which is not completely cut off remains at other positions of the left housing 101, the area of the bottom surface 10134 of the side wall of the left housing can be accurately deduced therefrom, and it can be further determined whether the foot 3 or the roller device 12 is mounted in the area of the bottom surface 10134 of the side wall of the left housing. For example, as shown in fig. 9, the front side 10132, the rear side 10133 and the bottom side 10134 of the left casing 101 have been cut by machining, and only the left casing side wall top side 10131 remains, and since the left casing side wall bottom side 10134 and the open end edge 10121 of the left casing side wall top side 10131 are located in the same plane before cutting, the position of the open end edge 10121 of the left casing side wall bottom side 10134 in the casing width W1 direction can be accurately deduced from the plane of the open end edge 10121 of the left casing side wall top side 10131, i.e., the width W1 at the left casing side wall bottom side 10134 can be determined. Since the left housing side wall bottom surface 10134 is formed by suction drawing from the left housing closed end 1011 toward the left housing open end 1012, the position of the left housing side wall bottom surface 10134 in the housing length L direction before cutting out can be deduced from the shape size of the left housing closed end 1011 at the housing bottom surface, i.e., the length of the left housing side wall bottom surface 10134 can be determined. The area of the left housing sidewall bottom surface 10134 can be accurately deduced from the width and length of the left housing sidewall bottom surface 10134, as shown in the dashed area of fig. 9. In order to facilitate the plastic sucking processing of the left and right shells, the length L of the power generation equipment shell 1 is larger than the width W.

Similarly, for the right housing 102, if the right housing sidewall bottom surface 10234 is partially or completely cut away by machining, as long as a sidewall surface that is not cut away remains in other positions of the right housing 102, the area of the right housing sidewall bottom surface 10234 can be accurately deduced therefrom, and it can be further determined whether the foot 3 or the roller device 12 is mounted in the area of the right housing sidewall bottom surface 10234.
