DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0027] Some embodiments of the present invention are described below in conjunction with the accompanying drawings. Example

[0028] Combination Figure 1-7 As shown, this embodiment provides a waste heat power generation steam pipeline plugging device, including: a main body module 100 and a plugging module 200.

[0029] The main body module 100 includes an upper half ring 110, a lower half ring 120 arranged on one side of the upper half ring 110, bolts 130 symmetrically arranged and passing through the upper half ring 110 and the lower half ring 120, and a shell 140 integrally fixed to the upper half ring 110.

[0030] The upper half ring 110 and the lower half ring 120 cooperate with each other and are fixedly sleeved on the steam pipe to facilitate the sealing of the plugging module 200. The bolt 130 passes through the upper half ring 110 and the lower half ring 120 and engages with the nut to fix the upper half ring 110 and the lower half ring 120 together to ensure the stability of the plugging module 200. The shell 140 is used to install the plugging module 200.

[0031] The blocking module 200 includes a pressure plate 210 movably arranged in the inner cavity of the shell 140, a rubber pad 220 fixed at the bottom end of the pressure plate 210, a threaded rod 230 fixed at the top of the pressure plate 210 and extending out of the shell 140, an extrusion member 240 movably arranged in the inner cavity of the threaded rod 230 and extending out of the threaded rod 230, a threaded sleeve 250 rotatably installed at the top of the shell 140, an annular worm gear 260 fixedly sleeved on the outer surface of the threaded sleeve 250, and a driving member 270 installed at the top of the shell 140.

[0032] The pressing plate 210 is used to install the rubber pad 220, and the rubber pad 220 is used to be close to the leaking part of the steam pipe, so as to block the leaking part.

[0033] The threaded sleeve 250 is rotatably installed on the top of the shell 140, and the threaded rod 230 passes through the threaded sleeve 250. At the same time, the threaded rod 230 and the threaded sleeve 250 are meshed with each other, so that when the threaded sleeve 250 rotates, it can drive the threaded rod 230 to move downward. The downward movement of the threaded rod 230 presses the pressure plate 210 and the rubber pad 220, so that the rubber pad 220 fits tightly to the surface of the leaking part of the steam pipe, thereby sealing the leaking part of the steam pipe.

[0034] A cavity 231 is opened inside the threaded rod 230, and a flow channel 232 is opened on the bottom wall of the cavity 231 to pass through the pressure plate 210 and extend out of the rubber pad 220, and the cavity 231 is filled with sealant, so that the sealant in the cavity 231 can be delivered through the flow channel 232 to cover the surface of the steam pipe and the rubber pad 220, thereby making the surface of the steam pipe and the rubber pad 220 fit more closely.

[0035] Furthermore, a rubber plug 233 is embedded in the opening of the flow channel 232 to prevent the sealant from flowing out through the flow channel 232 when idle.

[0036] The extrusion piece 240 includes a piston 241 movably arranged in the cavity 231, a straight rod 242 with one end fixed to the top of the piston 241 and the other end extending out of the threaded rod 230, and a circular plate 243 fixed to the top of the straight rod 242. The piston 241 is tightly attached to the inner wall of the cavity 231. When the user presses down the circular plate 243, the piston 241 is driven downward by the straight rod 242 to squeeze out the sealant in the cavity 231.

[0037] The driving member 270 includes a fixing seat 271 symmetrically fixed on the top of the shell 140, a rotating shaft 272 rotatably mounted on the fixing seat 271, a worm 273 fixedly sleeved on the rotating shaft 272, and a knob 274 fixed on the end of the rotating shaft 272. The fixing seat 271 is used to install the rotating shaft 272 to maintain the stability of the rotating shaft 272 during rotation. The rotating shaft 272 is used to install the worm 273 and drive the worm 273 to rotate. At the same time, the worm 273 and the annular worm gear 260 are meshed with each other to facilitate the rotation of the annular worm gear 260. In addition, due to the one-way transmission between the annular worm gear 260 and the worm 273, it can be ensured that the threaded sleeve 250 will not loosen due to external force. The knob 274 is used to facilitate the user to rotate the rotating shaft 272.

[0038] The working principle and use process of the utility model are as follows: when in use, the upper half ring 110 and the lower half ring 120 are sleeved on the steam pipe, and the shell 140 is located at the leakage point of the steam pipe, and the two are fixed by bolts 130, and the extrusion piece 240 is pressed down to extrude the sealant in the cavity 231 through the flow channel 232, so that the sealant covers the surface of the steam pipe and the rubber cushion layer 220, and the knob 274 is turned to drive the rotating shaft 272 to rotate, and the rotation of the rotating shaft 272 drives the worm 273 to rotate, and the rotation of the worm 273 drives the annular worm gear 260 to rotate, and then drives the threaded sleeve 250 to rotate, and the rotation of the threaded sleeve 250 drives the threaded rod 230 to move downward, and the threaded rod 230 moves downward to pressurize the pressing plate 210 and the rubber cushion layer 220, so that the rubber cushion layer 220 is tightly attached to the surface of the leakage point of the steam pipe, thereby blocking the leakage point of the steam pipe.

[0039] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
