Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] In the prior art, when clamping and fixing the FRP membrane shell, two clamping plates are mostly used to clamp and fix the outer side of the FRP membrane shell. However, since the FRP membrane shell is cylindrical and its outer wall is relatively smooth, the clamping plates are prone to sliding when fixing it, resulting in poor fixing effect, thereby affecting the processing quality. The following describes a support and clamping structure for a FRP membrane shell provided by some embodiments of the present invention in conjunction with the accompanying drawings.

[0023] Example 1:

[0024] In order to effectively support and fix the FRP membrane shell body 1, Figure 1 、 Figure 2 and Figure 3 As shown, a support and clamping structure for a FRP membrane shell is proposed. A FRP membrane shell body 1 is provided, and a fixing mechanism 2 is provided on the FRP membrane shell body 1. The fixing mechanism 2 is used to effectively fix the FRP membrane shell body 1. An adjustment mechanism 3 is provided at the bottom of the fixing mechanism 2. The adjustment mechanism 3 is used to adaptively fix FRP membrane shell bodies 1 of different lengths.

[0025] In order to prevent the glass fiber reinforced plastic membrane shell body 1 from sliding and deflecting after being fixed, a fixing mechanism 2 is proposed. By installing two fixing plates 201 and two frustum blocks 208, the tops of the two fixing plates 201 are provided with slide grooves 202, the tops of the two fixing plates 201 are fixedly connected with fixing frames 203, the two fixing plates 201 are slidably connected with support plates 204, the bottoms of the two support plates 204 are fixedly connected with sliders, the two sliders are respectively located in the two slide grooves 202, the two fixing plates 201 are fixedly connected with fixing blocks, the other sides of the two fixing blocks are fixedly connected with electric push rods 205, the tops of the two support plates 204 are fixedly connected There is an adjustment plate 206, and the two adjustment plates 206 are fixedly connected to an adjustment rod 207 on the opposite side. A fixing assembly 209 is provided on the two frustum blocks 208. A plurality of round rods 2091 are fixedly connected to the two adjustment rods 207, and the plurality of round rods 2091 are provided with adjustment holes 2092. The outer sliding connection of the plurality of round rods 2091 is a round tube 2093, and one end of the plurality of round tubes 2093 is fixedly connected to a limit block 2094, and the other end of the plurality of round tubes 2093 is fixedly connected to a fixed ball 2095. The other side of the two frustum blocks 208 is provided with an adjustment groove 2096, and the two frustum blocks 208 are provided with a plurality of through grooves. 2097, multiple through slots 2097 on the same frustum block 208 are connected to the adjustment slot 2096, and multiple through slots 2097 on the same frustum block 208 are distributed in a circular array. The two fixing frames 203 are respectively connected to the fixed ends of the two electric push rods 205, and the movable ends of the two electric push rods 205 are respectively connected to the two support plates 204. The fixing assembly 209 is used to adaptively fix the two ends of the glass fiber reinforced plastic membrane shell body 1, and the positions of the two fixing frames 203 are respectively fixed by the two fixing plates 201, and the positions of the two frustum blocks 208 are respectively fixed by the two fixing frames 203. By fixing the two frustum blocks 208 are respectively placed in the circular holes at both ends of the FRP membrane shell body 1, and the multiple fixed balls 2095 are directed to move on the two frustum blocks 208 by adjusting the two electric push rods 205. At this time, the multiple circular tubes 2093 slide in the multiple adjustment holes 2092 of the multiple round rods 2091 through the multiple limit blocks 2094. As the two adjusting rods 207 slide in the two adjusting grooves 2096, the outer wall of the fixed ball 2095 gradually engages with the inner wall of the circular hole of the FRP membrane shell body 1, thereby completing the fixation of the FRP membrane shell body 1. At the same time, the structure can be applicable to FRP membrane shell bodies 1 of different diameters, which greatly improves the applicability of the structure.

[0026] Example 2:

[0027] On the basis of Example 1, the technical solution proposed in Example 1 is used to solve the problem that in the prior art, when the FRP membrane shell is clamped and fixed, it is mostly clamped and fixed by a clamping plate. However, since the FRP membrane shell is cylindrical, its outer wall is prone to sliding when fixed with the clamping plate, and the fixing effect is poor, thereby affecting the processing quality. However, when supporting and fixing the FRP membrane shell body 1 of different lengths, if the distance between the two frustum blocks 208 is a fixed value, the scope of application of this structure is greatly reduced.

[0028] In order to further improve the scope of application of the structure, combined with Figure 1 and Figure 4 As shown, an adjustment mechanism 3 is proposed, which is provided with a base plate 301, and two grooves 302 are symmetrically provided on the base plate 301, a circular hole is provided between the two grooves 302, and a bidirectional threaded rod 303 is rotatably connected in the two grooves, and the bottoms of the two fixed plates 201 are fixedly connected with threaded sleeves 304, and the two threaded sleeves 304 are respectively located on the two sections of the thread of the bidirectional threaded rod 303, and a servo motor for driving the bidirectional threaded rod 303 is installed on one side of the base plate 301. By adjusting the servo motor, the bidirectional threaded rod 303 can drive the two threaded sleeves 304 to move toward each other, so that the distance between the two fixing frames 203 on the two fixed plates 201 can be adaptively adjusted according to the length of the glass fiber reinforced plastic membrane shell body 1, thereby further improving the applicability of the structure.
