[0002] In helium-oxygen mixed gas diving or saturation diving with a mixed gas, the uniformity of the gas mixture is extremely important. Traditional mixing methods involve placing a high-pressure gas cylinder on the ground and rolling it back and forth, which requires two or more people to operate and also poses certain risks. In addition, existing mixing methods mostly mix the gas inside the cylinder by rotating it around an axis, resulting in a unidirectional mixing direction that cannot achieve a sufficiently uniform gas mixture, leading to low mixing efficiency and poor mixing effect.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described and explained below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments provided by this utility model without inventive effort are within the scope of protection of this utility model.

[0022] This utility model provides a high-pressure gas cylinder 50 mixed gas shaking device. Figure 1 , 2 This is a schematic diagram of the structure of the gas mixing device for a high-pressure gas cylinder 50 according to an embodiment of the present invention. (Reference) Figure 1 , 2 As shown, the high-pressure gas cylinder 50 gas mixing device includes a first mixing assembly 10 for supporting the high-pressure gas cylinder 50 and rotating the high-pressure gas cylinder 50 around its axis to mix the gas inside the high-pressure gas cylinder 50; a second mixing assembly 20 for rotating the high-pressure gas cylinder 50 around a radial line perpendicular to the horizontal plane to mix the gas inside the high-pressure gas cylinder 50; and a base 30 for fixing the first mixing assembly 10 and the second mixing assembly 20. Figure 3As shown, the second shaking assembly 20 includes: a first internal gear 201, a first external gear 202, a second external gear 203, a third external gear 204, and a first motor 205; the first internal gear 201 is fixedly connected to the chassis 30; the first external gear 202 is disposed inside the ring of the first internal gear 201, with its center coinciding with the center of the first internal gear 201, and the first external gear 202 and the first internal gear 201 are located on the same plane; the second external gear 203 is disposed inside the ring of the first internal gear 201 and is located on one side of the first external gear 202, with both sides meshing with the first internal gear 201 and the first external gear 202 respectively; the third external gear 204 is disposed inside the ring of the first internal gear 201 and is located on the other side of the first external gear 202, with both sides meshing with the first internal gear 201 and the first external gear 202 respectively; the first motor 205 is connected to the first external gear 202 through a rotating shaft.

[0023] Further as Figure 3 As shown, the second mixing component 20 consists of two identical structures, upper and lower. The first internal gear 201 is first connected and fixed to the chassis 30, and the first external gear 202 is connected to the first motor 205. When the first motor 205 is turned on, it drives the first external gear 202 to rotate, thereby driving the second and third external gears 204 to rotate, which in turn drives the first internal gear 201 to rotate, thereby driving the chassis 30 to rotate 360°, and thus driving all structures on the upper part of the chassis 30 (including the fixed high-pressure gas cylinder 50) to rotate 360°. The above-mentioned high-pressure gas cylinder 50 mixed gas mixing device, by setting the first mixing component 10 and the second mixing component 20, realizes the rotation of the high-pressure gas cylinder 50 in two directions: around the axis of the high-pressure gas cylinder 50 and in the radial direction perpendicular to the horizontal plane. This ensures mixing efficiency and mixing effect, and is used for mixing high-pressure gas cylinder 50 mixed gas on construction sites. It is commonly used in the preparation stage of helium-oxygen mixed gas diving and saturation diving, saving manpower and ensuring safe operation.

[0024] To ensure the stability of the shaking and mixing process, the first shaking component 10 is located directly below the center of the high-pressure gas cylinder 50.

[0025] Furthermore, the first shaking assembly 10 includes a plurality of wheels 101 rotatably fixedly connected to the chassis 30. The wheels 101 are arranged in pairs opposite each other on both sides of the high-pressure gas cylinder 50. The axis of each wheel 101 is parallel to the axis of the high-pressure gas cylinder 50 and tangent to it. The wheels 101 located on the same side of the high-pressure gas cylinder 50 are connected by an axle 102, which is parallel to the axis of the high-pressure gas cylinder 50. One end of the axle 102 is connected to a second motor 103. The first shaking assembly 10 also includes a fourth external gear 104 fixedly connected to the axle 102, and a second internal gear 105 sleeved on and meshing with the fourth external gear 104. The second internal gear 105 is fixedly connected to the wheels 101. In some embodiments, the number of wheels 101 is four, with two wheels 101 arranged as a group at the front and rear of the high-pressure gas cylinder 50 respectively. Specifically, two sets of wheels 101 on one side perpendicular to the rotation direction of wheel 101 are connected by axle 102. A second motor 103 is fixed to the chassis 30 via bracket 40. The second motor 103 is connected to axle 102 via a second internal gear 105 and a fourth external gear 104. When the second motor 103 is turned on, it drives axle 102 to rotate 360°, thereby driving the two sets of wheels 101 connected to axle 102 to rotate 360°. This side of the structure acts as the driving element. The rotation of the driving element causes the high-pressure gas cylinder 50 to rotate 360° in the same direction, and the two sets of wheels 101 on the opposite side act as driven elements and rotate accordingly.

[0026] In some embodiments, the chassis 30 is bolted to the wheels 101.

[0027] In some embodiments, a support 40 is also included, covering the high-pressure gas cylinder 50, the chassis 30, the first shaking assembly 10, and the second shaking assembly 20. Further, the support 40 is a steel frame or a wooden frame. The support 40 provides support; whether it is a steel frame or a wooden frame, it must ensure that the bottom of the support 40 is flat and has sufficient weight-bearing capacity.

[0028] The working process of the above-mentioned high-pressure gas cylinder 50 mixed gas shaking device is as follows:

[0029] When the first motor 205 is turned on, it drives the first external gear 202 to rotate, which in turn drives the second and third external gears 204 to rotate, which in turn drives the first internal gear 201 to rotate, which in turn drives the chassis 30 to rotate 360°, which in turn drives all the structures on the upper part of the chassis 30 (including the fixed high-pressure gas cylinder 50) to rotate 360°, so that the high-pressure gas cylinder 50 rotates around the radial line of the high-pressure gas cylinder 50 perpendicular to the horizontal plane to mix the gas inside the high-pressure gas cylinder 50.

[0030] The above technical solution uses two motors to achieve the self-rotation and left-right rotation of the high-pressure gas cylinder 50, thereby ensuring uniform mixing of the gas inside the high-pressure gas cylinder 50. To ensure the stability of the high-pressure gas cylinder 50, it can be secured to the structure with fabric straps.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
