[0002] Many amusement parks have water entertainment projects, including setting up floating platforms on the water surface and performing on the floating platforms, and the support and fixation of the floating platforms are usually completed by support piles. Existing support piles usually adopt a pull-out design, similar to the handle of a folding umbrella, and the length of the support piles is fixed by setting limit pins on the wall of the support tube. However, this type of support piles has the following problems: 1. The limit pins set on the wall of the support tube are easily affected by the outside world and lose their limiting effect. For example, if the limit pin is accidentally hit, the limit pin will retract, and the compressed support pile will retract at this time, which is very likely to cause an accident; 2. The diameter of each section of the support tube is reduced successively to achieve pulling, but if one section is damaged, it cannot be matched and replaced within time, which is more troublesome.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1:

[0025] like Figure 1-Figure 8As shown, a multi-section pull-out spiral support pile for fixing a floating platform on water is characterized in that it includes a support seat and a support rod assembly, the support rod assembly is installed on the support seat, the support rod assembly is connected by a plurality of support rods, the support rod includes a first support tube 101 and a second support tube 102, the first support tube 101 is slidably connected to the second support tube 102, a limiting ring is provided on the first support tube 101, so that the second support tube 102 cannot be completely separated from the first support tube 101, a first flange 104 is installed on the first support tube 101, and a third flange 106 is installed on the second support tube 102, which is fixed by bolts. The first flange 104 on one group of support rods is fastened to the third flange 106 on another group of support rods to form a support rod assembly; the inner wall of the second support tube 102 is provided with a threaded groove, the first flange 104 is rotatably connected to the control rod, the control rod is fixedly installed with a drive disk 108, the side wall of the drive disk 108 is fixedly connected with a pin 107, the pin 107 cooperates with the drive disk 108, the control rod is fixedly connected with a first twisting nut 113, the first twisting nut 113 is located on the side of the first flange 104 away from the first support tube 101, and the outer diameter of the first twisting nut 113 is smaller than the inner diameter of the third flange 106. The support seat includes a second flange 105, and a plurality of brackets 103 are fixedly connected to the second flange 105. The first support tube 101 and the second support tube 102 are both made of 304 stainless steel.

[0026] The personnel rotate the first twisting nut 113 to rotate the control rod, and the rotation of the control rod causes the driving disc 108 to drive the pin 107 to rotate. The pin 107 slides in the thread groove of the second support tube 102, so that the second support tube 102 extends or retracts from the first support tube 101. When the first twisting nut 113 does not rotate, the self-locking property of the thread end is used to keep the second support tube 102 immobile. The third flange 106 on the top support rod is fixed to the floating platform by bolts. The number of support rods included in the support rod assembly is determined according to the depth of the water. When the support rods are spliced, the first twisting nut 113 will be inserted into the third flange 106 of another support rod. The first twisting nut 113 on the bottom support rod will be protected by the bracket 103, and the first twisting nut 113 will be isolated from the outside world through the second support tube 102, thereby preventing the support rod from being accidentally retracted to the maximum extent, and improving the stability of the device; at the same time, since the extension length of 102 is determined by the rotation angle of the control rod, the length adjustment is more precise, rather than segmented. Since the support rod assembly is composed of a plurality of support rods, when one support is damaged, it can be quickly replaced.

[0027] Embodiment 2:

[0028] like Figure 5-Figure 6As shown, the control rod includes a second control rod unit 112 and a first control rod unit 109, the second control rod unit 112 is slidably connected to the first control rod unit 109, the second control rod unit 112 is rotatably connected to the first flange 104, the driving disk 108 is fixedly connected to the first control rod unit 109, and a spring 110 is arranged between the driving disk 108 and the first flange 104.

[0029] When the water level drops, the buoyancy of the floating platform given by water decreases. At this time, the gravity of the floating platform increases on the spring 110, and the spring 110 begins to be compressed. At this time, the floating platform will drop. The drop of the floating platform will cause the buoyancy it receives to increase again until it reaches equilibrium, and vice versa. By setting a retractable control rod and spring 110, the floating platform can be raised and lowered according to changes in the water level to cope with short-term water level fluctuations.

[0030] like Figure 6-Figure 8 As shown, a limiting column 111 is provided on the second control rod unit 112 for limiting the first control rod unit 109 .

[0031] In the initial state, there is a certain distance between the first control rod unit 109 and the limiting column 111. When the spring 110 is compressed by pressure, the first control rod unit 109 begins to approach the limiting column 111. After the first control rod unit 109 contacts the limiting column 111, if the weight of the items stored on the floating platform is too heavy, the floating platform will not continue to descend due to the support of the limiting column 111. By setting the limiting column 111, it can be ensured that the floating platform can have a protection mechanism to prevent the floating platform from sinking underwater due to excessive load.

[0032] like Figure 8 As shown, the limiting column 111 is threadedly connected to the second control rod unit 112, and the second twisting nut 114 is fixedly connected to the limiting column 111, and the outer diameter of the second twisting nut 114 is smaller than the inner diameter of the third flange 106. The limiting column 111 is threadedly connected to the second control rod unit 112, and the self-locking property of the thread is utilized to enable the limiting column 111 to play a supporting role, and can be adjusted according to actual conditions.

[0033] Working principle: the staff selects the number of support rods according to the water depth of the floating platform, and then connects a support rod to the support seat by bolts. At this time, the second support tube 102 on the support rod connected to the support seat has not been extended, and then the control rods and limit columns 111 of the remaining support rods are adjusted to make the corresponding second support tube 102 fully extended and the limit column 111 supports the first control rod unit 109, so that the control rod cannot be extended or retracted. Then, these control rods are assembled together by bolts, and then the control rod on the support rod connected to the support seat is manually adjusted to make the height of the top support rod rise close to the water surface, and then the top support rod is fixed to the floating platform by bolts, and then the control rod is further adjusted to make the water surface submerge half of the floating platform, and then the second torsion nut 114 is manually turned to adjust the distance between the limit column 111 and the first control rod unit 109 according to the height of the floating platform to prevent the floating platform from sinking completely into the water.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the present invention.
