Embodiment 1

[0036] Such as Figure 1-2 An anti-drowning swimming collar shown includes a swimming collar body, and the swimming collar body is provided with a drowning prevention mechanism 100. The second pipe body 2, the middle part of the first pipe body 1 is provided with a calcium carbide powder placement unit 11, and the calcium carbide powder placement unit 11 includes a group of circular paper sheets arranged at intervals, between which there are Calcium carbide powder. Furthermore, fences 12 are arranged on both sides of the calcium carbide powder placement unit 11 , and a set of rubber bands 121 are also arranged on the fence 12 . The side of the fence 12 close to the second pipe body 2 is also provided with an elastic ball 3 assembled with an acid agent and an elastic ball filled with a coolant. In addition, the body of the swimming collar is also provided with an elastic ball assembled with coolant. In addition, the second pipe body 2 is provided with a fence frame 21 near th...

Embodiment 2

[0046] On the basis of Example 1, the triggering material based on calcium carbide, dilute hydrochloric acid, and liquefied n-butane of the present embodiment, in terms of mass grams, its raw material triggering dosage is: 15 grams of calcium carbide, 32 cm 3 Dilute hydrochloric acid (0.027 mol / mL).

[0047] Its production process is as follows:

[0048] 15 grams of calcium carbide powder is placed in the middle of the first tube body 1 with a length of 110mm and D30×1mm, covered with a circular thin paper sheet, and then placed on both sides of a fence with a diameter of D18.9mm and a thickness of 1mm, and then stuffed into a 16cm 3 The rubber ball of dilute hydrochloric acid is covered with round thin paper in the same way; then the second tube body 2 with a length of 25 mm and D27.9 × 1 mm is put on both sides, and inserted into a depth of 10 mm; one end of the second tube body 2 is a fence frame 21, The fence frame 21 is equipped with 3 mm spikes 22; one end of the spikes...

Embodiment 3

[0050] On the basis of Example 1, the triggering material based on calcium carbide and dilute hydrochloric acid in this embodiment is calculated in grams by mass, and its raw material triggering dosage is: 15 grams of calcium carbide, 32 cm 3 Dilute hydrochloric acid (0.027 mol / mL).

[0051] Its production process is as follows:

[0052] 15 grams of calcium carbide powder is placed in the middle of the first tube body 1 with a length of 110mm and D30×1mm, covered with a circular thin paper sheet, and then placed on both sides of a fence with a diameter of D18.9mm and a thickness of 1mm, and then stuffed into a 16cm 3 The rubber ball of dilute hydrochloric acid is covered with round thin paper in the same way; then the second tube body 2 with a length of 25 mm and D27.9 × 1 mm is put on both sides, and inserted into a depth of 10 mm; one end of the second tube body 2 is a fence frame 21, 3mm spikes 22 are on the fence frame 21, and a large hole is opened in the middle of the o...

Abstract

A drowning-proof swimming collar includes a swimming collar body, wherein the swimming collar body is provided with a drowning prevention mechanism; the drowning prevention mechanism comprises a firstpipe body and a second pipe body penetrated on both sides of the first pipe body; a calcium carbide powder placing unit is arranged in the middle of the first pipe body; the two sides of the calciumcarbide powder placing unit are provided with a fence, and an elastic ball assembled with an acid agent is arranged on one side of the fence near the second pipe body; at one end of the second pipe body close to the first pipe body, a fence frame is arranged; the fence frame is provided with a sharp spine; and at the other end of the second pipe body, a dragging belt is arranged. The drowning-proof swimming collar has a reasonable structure, uses calcium carbide and an acid agent as triggering substances to generate acetylene gas and salt, and expands in the body of the swimming collar to forma lifebuoy, so as to achieve the effect of preventing drowning. As the product is salt, the risk that the product will corrode the skin once the product is leak when the product is alkali can be avoided.

Description
