[0002] The Argo program is an international ocean observation experiment project that plays a vital role in the fields of global ocean hydrological element observation and global climate change. In the international Argo program, each Argo float can operate in the ocean for several years and complete the measurement of ocean environmental profile elements (such as temperature, salinity, dissolved oxygen, nutrients and bio-optical parameters) every certain number of days.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1

[0032] Reference Figure 1 and Figure 2 , which is the first embodiment of the present invention, provides an antenna height adjustment device for an Argo float. The antenna height adjustment device for an Argo float includes a main body component 100 and an adjustment component 200.

[0033] Specifically, the main body component 100 includes a shell 101, and the shell 101 has a partition 101a inside. The partition 101a divides the shell 101 into a first chamber 101b and a second chamber 101c, and an annular groove 101a-1 is also provided on the top of the partition 101a. The shell 101 is cylindrical as a whole, and the partition 101a is fixedly connected to the inside of the shell 101. A hole is provided at the center of the partition 101a, and the annular groove 101a-1 is concentric with the hole, and its side wall has a certain height.

[0034] Preferably, the adjustment assembly 200 is arranged inside the housing 101, and includes a driving member 201, a moving member 202 arranged inside the first chamber 101b, and a sealing member 203 arranged inside and on the top of the partition 101a. The driving member 201 provides power for the device, and the moving member 202 can control the sinking and floating of the buoy. The sealing member 203 can seal the device.

[0035] When in use, the buoy is placed in the sea, and part of the seawater will enter the first chamber 101b. Since there is still air inside the first chamber 101b, the buoy will not sink at this time. When the driving member 201 drives the moving member 202 to move vertically upward, the seawater will enter the moving member 202, and the buoy can sink at this time. When the buoy needs to float up, the moving member 202 can be moved vertically downward by the driving member 201, and the seawater is discharged from the moving member 202, and the buoy floats up. In addition, when the buoy reaches the sea surface, the height of the buoy floating out of the sea surface can also be controlled by the moving member 202.

[0036] Example 2

[0037] Reference Figure 2 to Figure 8 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0038] Specifically, at least one first water-permeable hole 101d is provided on the surface of the shell 101, and the first water-permeable hole 101d connects the outside with the first chamber 101b. The first water-permeable holes 101d are evenly arranged around the shell 101, and are located close to the top of the partition 101a. When the buoy is placed in the sea, seawater can enter the first chamber 101b from the first water-permeable hole 101d.

[0039] Preferably, the driving member 201 comprises a motor 201a disposed inside the second chamber 101c and an encoder 201b disposed on the motor 201a; the motor 201a can be a servo motor or a stepper motor, etc., which can accurately control the rotation of the screw 201c. The encoder 201b is used to detect the number of revolutions and the forward and reverse directions of the motor 201a.

[0040] The driving member 201 further includes a screw rod 201c disposed at the output end of the motor 201a, the screw rod 201c passing through the partition 101a and extending to the top of the first chamber 101b. The motor 201a drives the screw rod 201c to rotate, and there is no thread at the connection between the screw rod 201c and the partition 101a. The screw rod 201c and the partition 101a are rotationally matched, and a mechanical seal is provided at their connection to prevent seawater from entering the second chamber 101c.

[0041] Preferably, the moving member 202 includes a moving cylinder 202a disposed inside the first chamber 101b, the moving cylinder 202a is threadedly matched with the screw rod 201c, and a third chamber 202a-1 is disposed inside the moving cylinder 202a. When the screw rod 201c rotates, the moving cylinder 202a can move along the axial direction of the screw rod 201c, and when the rotation direction of the screw rod 201c is different, the moving direction of the moving cylinder 202a is also different.

[0042] Preferably, at least one second water-permeable hole 202a-2 is provided on the side wall of the moving cylinder 202a, and the second water-permeable hole 202a-2 connects the first chamber 101b with the third chamber 202a-1; the second water-permeable holes 202a-2 are evenly arranged around the moving cylinder 202a, and are used for seawater to enter and exit the third chamber 202a-1. A sliding groove 202a-3 is also provided inside the side wall of the moving cylinder 202a.

[0043] Preferably, mobile member 202 also comprises the expansion cover 202b that is arranged at the top of mobile cylinder 202a, and the expansion cover 202b part places in the sliding groove 202a-3 and cooperates with the sliding movement of mobile cylinder 202a, and the sidewall of expansion cover 202b is provided with the 3rd water permeable hole 202b-1, and in sliding groove 202a-3, is also provided with the first spring 202c.Expansion cover 202b is inserted in the sliding groove 202a-3, and expansion cover 202b can be pulled out when needed, but its bottom does not leave sliding groove 202a-3.The first spring 202c is a tension spring, and two ends are fixedly connected with the bottom of expansion cover 202b and the bottom of sliding groove 202a-3 respectively.Under normal condition, the first spring 202c pulls expansion cover 202b, and closely fits the top of mobile cylinder 202a.

[0044] Preferably, the moving member 202 also includes a limiting rod 202d arranged in the first chamber 101b, and one end of the limiting rod 202d is placed in the third chamber 202a-1, and is slidably matched with the expansion cover 202b. The top of the limiting rod 202d is fixedly connected to the top of the first chamber 101b, and the other end extends into the inside of the moving cylinder 202a, and this end is wider, and its shape is perfectly fitted with the third chamber 202a-1. When the moving cylinder 202a continues to move downward, the expansion cover 202b can be hooked by this end of the limiting rod 202d, thereby being pulled out a distance, thereby increasing the overall volume of the moving cylinder 202a. On the other hand, under the initial state, the wider end sidewall of the limiting rod 202d is close to the inner wall of the moving cylinder 202a, and the second water-permeable hole 202a-2 and the third water-permeable hole 202b-1 can be blocked just in time, preventing seawater from entering the third chamber 202a-1. It should be noted that the wider end of the limiting rod 202d and the inner wall of the moving cylinder 202a are provided with a seal, which has a good sealing effect.

[0045] Preferably, the seal 203 includes a first sealing block 203a and a second sealing block 203b disposed inside the partition 101a, and the ends of the first sealing block 203a and the second sealing block 203b are provided with a wedge-shaped groove 203c and a second spring 203d, and the thickness of the second sealing block 203b is less than that of the first sealing block 203a. Two first sealing blocks 203a are symmetrically provided, each of which has a semicircular end, and the two can form a complete ring together, and a sealing rubber pad is provided on the end surface thereof. The second spring 203d is a compression spring, which can keep the first sealing block 203a close to the smooth part of the screw rod 201c under normal conditions.

[0046] Furthermore, the first sealing block 203a and the second sealing block 203b are arc-shaped, and a notch 203a-1 is provided at the arc-shaped end of the first sealing block 203a, and the arc-shaped end of the second sealing block 203b is placed in the notch 203a-1. The arc-shaped end of the second sealing block 203b should be less than 180°, and it is nested with the first sealing block 203a, which can achieve a better sealing effect.

[0047] Furthermore, the seal 203 also includes an annular plate 203e disposed inside the annular groove 101a-1, a plug rod 203e-1 is disposed at the bottom of the annular plate 203e, the end of the plug rod 203e-1 is wedge-shaped and cooperates with the wedge-shaped groove 203c, and a pressure rod 203e-2 is also disposed at the top of the annular plate 203e, one end of the pressure rod 203e-2 abuts against the bottom of the moving cylinder 202a. On the one hand, when the buoy dives deeper and deeper, the seawater pressure becomes greater and greater, and the annular plate 203e is affected by the seawater pressure, and the plug rod 203e-1 will squeeze the wedge-shaped groove 203c so that the first sealing block 203a and the second sealing block 203b press the smooth part of the screw rod 201c, strengthen the seal, and prevent water seepage under high pressure. On the other hand, when the moving cylinder 202a moves downward, its bottom squeezes the pressure rod 203e-2, which can also play a role in strengthening the seal.

[0048] When the buoy is put into the sea, seawater will enter the first chamber 101b from the first water-permeable hole 101d. Since there is air in the first chamber 101b, the buoy will not sink temporarily. When the motor 201a is started to rotate, the screw rod 201c will drive the moving cylinder 202a to move upward (it should be noted that the moving cylinder 202a is located at the bottom of the first chamber 101b in the initial state and presses the pressure rod 203e-2). When the moving cylinder 202a moves upward, the end of the limiting rod 202d inside it will move downward relatively and leave the position of the second water-permeable hole 202a-2 and the third water-permeable hole 202b-1. At this time, seawater will enter the third chamber 202a-1 from the second water-permeable hole 202a-2 and the third water-permeable hole 202b-1, and the buoy will sink. During the sinking process, although the pressure rod 203e-2 loses the squeezing of the moving cylinder 202a, as the depth continues to increase, the pressure becomes greater and greater, and the sea water pressure will squeeze the annular plate 203e downward, and then the first sealing block 203a and the second sealing block 203b will be pressed together through the cooperation of the insertion rod 203e-1 and the wedge-shaped groove 203c, thereby strengthening the seal.

[0049] If it is necessary to rise, the motor 201a drives the screw rod 201c to rotate in the opposite direction, the moving cylinder 202a moves downward, and the limit rod 202d moves upward relatively, and at the same time, the seawater in the third chamber 202a-1 is discharged from the second water-permeable hole 202a-2 and the third water-permeable hole 202b-1. At this time, the displacement volume of the buoy increases, the buoyancy increases, and the buoy begins to float until it floats to the sea surface. Moreover, when the moving cylinder 202a moves downward, its bottom can also press the pressure rod 203e-2 so that the first sealing block 203a and the second sealing block 203b strengthen the seal. In addition, if the moving cylinder 202a continues to move downward, the expansion cover 202b will be pulled up by the limit rod 202d, thereby increasing the volume of the moving cylinder 202a, that is, increasing the displacement volume of the buoy, which can increase the height of the buoy on the sea surface, and the satellite antenna obtains a greater floating height, improving the reliability of communication.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
