DETAILED DESCRIPTION

[0025] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0026] It is to be noted that the concepts of directions “left”, “right”, “up”, “down”, “front”, “back”, “inside” and “outside” in the following schemes are all relative directions and are not listed one by one here.

[0027] A welding device for the inverted installation of photothermal molten salt storage tanks, reference Figure 1-Figure 4 , including a fixing assembly 6. The fixing assembly 6 includes a fixing base 61. The fixing base 61 is provided with a plurality of fixing bolts 62 for fixing it to the ground. An electric push rod 63 is detachably provided on the upper side of the fixing base 61. A fixing block 41 is detachably provided on the upper end of the electric push rod 63. The detachable connection method includes bolt installation, thread installation, etc., which will not be described in detail here.

[0028] A handle 48 is provided on the fixed block 41. A worm 51 and a worm wheel 52 are rotatably provided in the fixed block 41 and mesh with each other. The worm 51 is connected to the handle 48. A first gear 42 is fixedly connected to the right side of the fixed block 41. A rotating rod 43 is connected to the worm wheel 52. The rotating rod 43 is rotatably provided through the center of the first gear 42. A placement seat 44 is fixedly connected to the lower end of the rotating rod 43. A second gear 45 and a third gear 46 are rotatably provided on the left side of the placement seat 44. The second gear 45 and the third gear 46 are fixedly connected at the center by a first connecting rod. The second gear 45 meshes with the first gear 42. A fourth gear 47 is meshed on one side of the third gear 46. The fourth gear 47 is rotatably provided on the left side of the placement seat 44. One end of the connector 1 is detachably rotatably provided on the right side of the placement seat 44. One end of the connector 1 is fixedly connected to the center of the fourth gear 47 by a second connecting rod. The connector 1 is detachably connected to the second connecting rod. The detachable connection method includes bolt installation, thread installation, etc., which will not be described in detail here. The second connecting rod is rotatably connected to the placement seat 44. Although the gears shown in the figure are all spur gears, it does not mean that the gears used in actual applications are spur gears. Bevel gears can also be used according to actual conditions. The ultimate purpose is just to achieve gear meshing transmission.

[0029] A pointing body 7 is provided on one end of the connector 1 away from the placement seat 44. A reset telescopic assembly 2 is rotatably provided on the lower side of the pointing body 7. The reset telescopic assembly 2 includes a mother rod 22 and a child rod 23 that are slidably sleeved and connected to each other. The mother rod 22 is connected to the right side of the connector 1. The mother rod 22 is hollow inside and is provided with a reset spring 21. The two ends of the reset spring 21 are respectively abutted against the inner wall of the mother rod 22 and the end of the child rod 23. A welding part 3 is provided at one end of the child rod 23 located outside the mother rod 22. A pointing member that always points to the center of the photothermal molten salt storage tank is rotatably provided in the pointing body 7, and the pointing member is connected to the reset telescopic assembly 2. As for how to realize that the pointing member always points to the center of the photothermal molten salt storage tank, the compass principle can be adopted. An electromagnet is provided at the center of the photothermal molten salt storage tank, and the pointing member is made of a magnet. When the electromagnet is energized, it can be ensured that no matter how it moves, the pointing member always points to the electromagnet.

[0030] After the present embodiment is installed and the fixing assembly 6 is fixed on the ground, the handle 48 is turned, and the handle 48 rotates with the placement seat 44 ( Figure 2 The second gear 45 moves along the circumference of the first gear 42 (the rotation direction is counterclockwise when viewed from top to bottom). Figure 2 The rotation direction is counterclockwise when viewed from top to bottom). Since the second gear 45 and the first gear 42 are in meshing state, the second gear 45 will rotate on its own during the movement of the second gear 45 ( Figure 2 The rotation direction is clockwise when viewed from right to left). The second gear 45 rotates to drive the third gear 46 to rotate ( Figure 2 The rotation direction is clockwise when viewed from right to left). As the third gear 46 is meshed with the fourth gear 47, the fourth gear 47 rotates ( Figure 2 The rotation direction is clockwise when viewed from top to bottom). The fourth gear 47 rotates to drive the connector 1 to rotate. The placement seat 44 moves counterclockwise around the rotating rod 43, and the connector 1 moves clockwise around the fourth gear 47 at the end away from the fourth gear 47. Since the movement of the placement seat 44 is opposite to the rotation direction of the connector 1, it is only necessary to control the dimensions of the first gear 42, the second gear 45, the third gear 46, the fourth gear 47, the placement seat 44 and the connector 1 so that the counterclockwise rotation angle of the placement seat 44 and the clockwise rotation angle of the fourth gear 47 are offset at the end of the connector 1 away from the placement seat 44, and finally the end of the connector 1 away from the placement seat 44 finally moves in a straight line.

[0031] During the movement, the pointing piece rotates due to the magnetic force, thereby adjusting the rotation angle of the welding piece 3 so that its end is always aligned with the center of the solar thermal molten salt storage tank.

[0032] As the welding part 3 moves, the distance between the welding part 3 and the weld may change. Due to the presence of the reset spring 21, the reset spring 21 is in a compressed state, ensuring that the end of the welding part 3 is always in contact with the weld, thereby ensuring the overall welding effect.

[0033] The above is only a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above description or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art shall not deviate from the spirit and scope of the present invention, and shall be within the scope of protection of the claims attached to the present invention.
