[0003] The existing molten salt pipelines have the following problems in use:

[0004] In actual life, when the molten salt pipeline is installed in the heat absorption tower, it is usually fixed by using multiple bolts, which is rather troublesome and has a low installation efficiency. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantages that in actual life, when the molten salt pipeline is installed in the heat absorption tower, it is usually fixed by using multiple bolts, which is rather troublesome and has a low installation efficiency, and to provide a molten salt pipeline layout structure in a solar thermal power generation heat absorption tower.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A molten salt pipeline layout structure in a solar thermal power generation heat absorption tower, including a tower body, a stairwell and an elevator shaft are arranged in the tower body, a cold molten salt pipeline and a hot molten salt pipeline are arranged in the tower body, the cold molten salt pipeline and the hot molten salt pipeline are on the same horizontal plane, and a door body is installed on one side of the tower body;

[0008] A fixing mechanism is arranged in the tower body for fixing the cold molten salt pipeline and the hot molten salt pipeline;

[0009] A stabilizing mechanism is arranged in the tower body for improving the stability of the cold molten salt pipeline and the hot molten salt pipeline.

[0010] In a possible design, the fixing mechanism includes two first fixing clips, two second fixing clips, four first clamping plates and four first threaded rods. One side of each of the two first fixing clips is fixedly connected to the inner wall of one side of the tower body, and one side of each of the two second fixing clips is fixedly connected to the inner wall of one side of the tower body. One side of the four first clamping plates is respectively fixedly connected to the inner wall of one side of the two first fixing clips and the inner wall of one side of the second fixing clips. A second clamping plate is slidably connected to the inner wall of one side of each of the two first fixing clips and the inner wall of one side of the two second fixing clips. The four first threaded rods are respectively threadedly connected to the two first fixing clips and the two second fixing clips. One end of the first threaded rod is rotatably connected to one side of the second clamping plate, and the other end of the first threaded rod is fixedly provided with a first knob facilitating the rotation of the first threaded rod.

[0011] In a possible design, the stabilizing mechanism includes a first fixing plate, a second fixing plate and two insertion frames. One side of the first fixing plate and one side of the second fixing plate are both fixedly connected to the inner wall of one side of the tower body. Slots are formed on one side of the first fixing plate and one side of the second fixing plate. The two insertion frames are respectively inserted into the slots of the first fixing plate and the second fixing plate. Second threaded rods are respectively threadedly connected to the first fixing plate and the second fixing plate. The top end of the second threaded rod is fixedly provided with a second knob facilitating the rotation of the second threaded rod. A jack is formed on the insertion frame, and the bottom end of the second threaded rod is inserted into the jack.

[0012] In a possible design, sliding grooves for improving the stability of the second clamping plate are formed on the inner wall of one side of the first fixing clip and the inner wall of one side of the second fixing clip. A sliding block is fixedly provided on one side of the second clamping plate, and one side of the sliding block is slidably connected to the inner wall of the sliding groove.

[0013] In a possible design, the shapes of the first clamping plate and the second clamping plate are both arc-shaped.

[0014] In a possible design, the length of the first fixing plate is less than the length of the second fixing plate, and the length of the first fixing clip is less than the length of the second fixing clip.

[0015] In this application, during installation, first install the hot molten salt pipeline. Place the hot molten salt pipeline between the first clamping plate and the second clamping plate of the second fixing clip. Then rotate the first knob. The rotation of the first knob drives the rotation of the first threaded rod, and the rotation of the first threaded rod drives the rotation of the second clamping plate. Clamp and fix the hot molten salt pipeline through the first clamping plate and the second clamping plate. Then place the cold molten salt pipeline between the first clamping plate and the second clamping plate within the first fixing clip, and by rotating the first knob again, clamp and fix the cold molten salt pipeline through the first clamping plate and the second clamping plate. Thus, the hot molten salt pipeline and the cold molten salt pipeline can be clamped and fixed, eliminating the need for installation with multiple bolts, which is more convenient. To improve the stability of the cold molten salt pipeline and the hot molten salt pipeline, insert the two insertion frames into the slots of the first fixing plate and the second fixing plate respectively, so that the hot molten salt pipeline is located between the first fixing plate and the insertion frame, and the cold molten salt pipeline is located between the second fixing plate and the insertion frame. Then sequentially rotate the two second knobs. The rotation of the second knobs drives the rotation of the second threaded rods, and one end of the second threaded rods is inserted into the jacks of the insertion frames, thereby improving the stability of the hot molten salt pipeline and the cold molten salt pipeline. Since the hot molten salt pipeline and the cold molten salt pipeline are on the same horizontal plane, the occupied area inside the tower can be effectively reduced.

[0016] The beneficial effects of the present utility model are as follows:

[0017] In the present utility model, for the molten salt pipeline layout structure inside the solar thermal power generation heat absorption tower, through the fixing mechanism, place the hot molten salt pipeline between the first clamping plate and the second clamping plate of the second fixing clip. Then rotate the first knob. The rotation of the first knob drives the rotation of the first threaded rod, and the rotation of the first threaded rod drives the rotation of the second clamping plate. Clamp and fix the hot molten salt pipeline through the first clamping plate and the second clamping plate. Then place the cold molten salt pipeline between the first clamping plate and the second clamping plate within the first fixing clip, and by rotating the first knob again, clamp and fix the cold molten salt pipeline through the first clamping plate and the second clamping plate. Thus, the hot molten salt pipeline and the cold molten salt pipeline can be clamped and fixed, eliminating the need for installation with multiple bolts, which is more convenient;

[0018] In the present utility model, for the molten salt pipeline layout structure inside the solar thermal power generation heat absorption tower, through the stabilizing mechanism, insert the two insertion frames into the slots of the first fixing plate and the second fixing plate respectively, so that the hot molten salt pipeline is located between the first fixing plate and the insertion frame, and the cold molten salt pipeline is located between the second fixing plate and the insertion frame. Then sequentially rotate the two second knobs. The rotation of the second knobs drives the rotation of the second threaded rods, and one end of the second threaded rods is inserted into the jacks of the insertion frames, thereby improving the stability of the hot molten salt pipeline and the cold molten salt pipeline;

[0019] In the present utility model, the molten salt pipeline and the cold molten salt pipeline can be clamped and fixed through the fixing mechanism, so that it is no longer necessary to install with multiple bolts, which is more convenient. The stability of the molten salt pipeline and the cold molten salt pipeline can be improved through the stabilizing mechanism. BRIEF DESCRIPTION OF THE DRAWINGS
