Similarly, the closed end 1021 of the right casing and the top surface 10231, front 10232, back 10233 and bottom 10234 of the right casing side wall are of an integral structure, forming the right casing 102 of plastic material.

Of course, after the trimming process is performed on the left and right plastic-absorbing shells, the front and rear surfaces of the side walls of the left and right shells can be completely or partially cut off by mechanical cutting process, so as to leave an opening space for installing the front cover 104 and the rear cover 105. As shown in fig. 9 and 15, the left housing front opening 1015 and the right housing front opening 1025 match the shape of the front cover 104, leaving an open space for mounting the front cover 104; left and right

housing rear openings

1014, 1024 match the shape of rear cover 105, leaving open space for mounting rear cover 105. Of course, in order to mount the separate chassis base, the bottom surfaces of the left and right casing sidewalls may be further completely or partially cut off by machining, and only the top surfaces of the left and right casing sidewalls are remained. In order to make full use of the blister shell blank material, the utility model discloses require, have at least one face can not be amputated completely in four faces of top surface, front, back and bottom surface that constitute left and right casing lateral wall, and this face forms an organic whole structure with the closed end of left and right casing, will remain the lateral wall of blister shell at least. Specifically, left housing closed end 1011 is integrally formed with at least one of the four sides of left housing sidewall top surface 10131, front surface 10132, rear surface 10133 and bottom surface 10134, and right housing closed end 1021 is integrally formed with at least one of the four sides of right housing sidewall top surface 10231, front surface 10232, rear surface 10233 and bottom surface 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 connected by the connecting member 103 in a splicing manner, so that under the condition that the total width W of the power generating equipment casing is constant, since the width W1 of the left and right casing side walls is wide, the width W1 of the casing side wall can be maximally utilized when the left and right casings are connected at the position of the side wall which is not cut off, the width W2 of the connecting member 103 is small, which is beneficial to reducing the cost of the connecting member 103. As shown in fig. 14, the side wall width W1 of the left casing 101 and the right casing 102 may be different, in order to utilize the plastic suction casing side wall as much as possible, the utility model discloses the requirement: the width W1 of the larger side wall width of the left housing 101 or the right housing 102 should be at least greater than half of the width W2 of the connecting member 103, i.e. the dimension relationship between the width W1 of the left and right housing side walls and the width W2 of the connecting member 103 is: . In practice, the best design should be: w1> W2, namely: the width W1 of the side wall of the left shell 101 or the right shell 102 should be greater than the width W2 of the connecting member 103. Note that: since the sidewalls of the left and right housings may be partially cut away, for example, at the front opening 1015 and the rear opening 1014 of the left housing, the sidewall width W1 should be the width before the sidewalls are cut away, and the maximum width of the sidewalls after the sidewalls are cut away.

It should be noted that the utility model discloses left and right casing plastic uptake shaping needs to cut edge the processing to the open end of the casing after obtaining the casing blank, will form open end border 10121 at the lateral wall end of left casing open end after cutting edge processing, as shown in fig. 11. Due to the technical characteristics of the trimming process, the open end edge 10121 of the peripheral ring of the left shell is 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 side wall of the left shell are located in the same plane. Thus, even if one or more of the top surface 10131, front surface 10132, rear surface 10133 and bottom surface 10134 of the left housing sidewall is completely cut away, as long as one sidewall surface remains not completely cut away, the location and size of this sidewall surface area prior to cutting away can be inferred from the location of this sidewall surface end and the shape of the left housing closed end 1011. Note that: the utility model discloses only require footing 3 to set up in casing lateral wall bottom surface region, whether have physical structure irrelevantly with the lateral wall bottom surface of plastic uptake casing, footing 3 also must not directly link to each other with casing lateral wall bottom surface. Therefore, even if the utility model provides a left casing lateral wall bottom surface 10134 is partly or completely excised through machining, as long as the other positions of left casing 101 still remain a lateral wall face that is not completely excised, then can accurately infer left casing lateral wall bottom surface 10134 area in view of the above, and then can judge whether footing 3 or roller device 12 are installed in left casing lateral wall bottom surface 10134 area. For example, as shown in fig. 9, the front side wall 10132, the rear side 10133 and the bottom 10134 of the left casing 101 have been cut off by machining, only the top side wall 10131 of the left casing remains, and since the bottom side wall 10134 of the left casing before cutting off is located in the same plane as the open end edge 10121 of the top side wall 10131 of the left casing, the position of the open end edge 10121 of the bottom side wall 10134 of the left casing in the direction of the casing width W1 can be accurately inferred from the plane of the open end edge 10121 of the top side wall 10131 of the left casing, that is, the width W1 of the bottom side wall 10134 of the left casing can be determined. Since the left case side wall bottom surface 10134 is formed by suction drawing from the left case closed end 1011 toward the left case open end 1012, the position of the left case side wall bottom surface 10134 in the case length L direction before cutting can be inferred from the size of the shape of the left case closed end 1011 at the case bottom surface, that is, the length of the left case side wall bottom surface 10134 can be determined. The area of the left housing sidewall bottom surface 10134 can be accurately inferred from the width and length of the left housing sidewall bottom surface 10134, as shown by the dashed area in fig. 9. For the convenience of left and right casing plastic uptake processing, the utility model discloses length L of power generation equipment casing 1 is greater than 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 at other positions of the right housing 102, the area of the right housing sidewall bottom surface 10234 can be accurately inferred, and it can be determined whether the foot 3 or the roller device 12 is mounted in the area of the right housing sidewall bottom surface 10234.
