Detailed Implementation

[0022] The present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1-3As shown, a float-type water level wave measuring device includes a float 3. The float 3 is generally shaped like a microphone, with a sphere at the top and a cylinder at the bottom. Its internal structure is divided into three chambers from top to bottom: a first chamber, a second chamber, and a third chamber.

[0024] The first chamber is the measurement, communication control, and power supply layer, used for water level and wave monitoring, remote communication control, and power supply for all electrical equipment inside the float 3. The first chamber is located in the upper half of the float sphere. Solar panels and brackets 4 are installed around the first chamber. Equipment cabinets 5 and battery cabinets 6 are installed at the bottom of the first chamber. A pole 2 is installed in the center of the first chamber. A Beidou-3 short message terminal 1 based on precise single-point positioning is installed on the pole 2. The top of the sphere is transparent.

[0025] The second chamber is the anchor chain release and recovery layer, used for the release and recovery of the anchor chain 10. The second chamber is located in the lower half of the float sphere. The second chamber is equipped with a first motor 8-1 and a second motor 8-2. The rotating shafts of the first motor 8-1 and the second motor 8-2 are clamped to the left and right by the drum 12 via a drum coupling. A drum box 7 is provided on the outside of the drum 12. An anchor chain 10 is provided on the drum 12. One end of the anchor chain 10 is fixed to the drum 12, and the other end of the anchor chain 10 is connected to the sinker 11.

[0026] The third chamber is a filler layer used to lower the center of gravity of the float 3 and improve its static stability. The third chamber is located at the bottom of the sphere and the cylindrical part of the float. A through tube is provided in the center of the third chamber, penetrating the sphere and the cylinder. A counterweight, such as sand, is filled between the through tube and the side wall of the cylinder. The top and bottom of the inner wall of the through tube are welded with discs. The discs have holes in the center, and the size of the holes is slightly larger than the outer diameter of the anchor chain 10 so that the anchor chain 10 can pass through. One end of the anchor chain 10 connected to the sinker 11 passes through the lower end of the through tube and is connected to the sinker 11 via a metal ring.

[0027] The Beidou-3 short message terminal 1, based on precise single-point positioning, is fixed to the pole 2 by stainless steel cable ties.

[0028] The first bearing and seal 13-1 and the second bearing and seal 13-2 are respectively installed on the two side walls of the drum box 7 for supporting and sealing the shafts of the first motor 8-1 and the second motor 8-2.

[0029] The upper part of the tube is filled with soft absorbent material 9, and the soft absorbent material 9 wraps the anchor chain 10.

[0030] The first chamber consists of a transparent plastic shell and a metal base plate, with the uprights 2, solar panels and brackets 4, equipment cabinets 5 and battery cabinets 6 all fixed to the first metal base plate.

[0031] The second chamber consists of a waterproof metal outer shell and a metal base plate, one above the other.

[0032] The third chamber consists of a waterproof metal outer shell and a metal base plate, which together form a counterweight-containing space.

[0033] The Beidou-3 short message terminal 1 based on precise single-point positioning is used for Beidou PPP-B2b precise single-point positioning, and sends positioning information, calculated water level value and wave element value to the remote monitoring center in the form of short messages, while receiving control commands in the form of Beidou short messages issued by the remote monitoring center.

[0034] The solar panel and bracket 4 and the battery cabinet 6 are used to provide power to all electrical equipment inside the float;

[0035] Equipment cabinet 5 is used for automatic power switching, and at the same time, it obtains control commands from Beidou-3 short message terminal 1 based on precise single-point positioning to automatically control the release and recovery of anchor chain 10.

[0036] The drum box 7 is used to isolate the water-wet anchor chain 10 from the first motor 8-1 and the second motor 8-2, which require a dry operating environment;

[0037] The drum box 7, the first motor 8-1, the second motor 8-2, the anchor chain 10, the sinker 11, the drum 12, the first bearing and seal 13-1, and the second bearing and seal 13-2 are used together for the release and recovery of the anchor chain 10;

[0038] The soft absorbent material 9 is used to absorb the moisture brought in during the process of recycling the anchor chain 10, so as to ensure the dryness of the working environment of the electrical equipment inside the float 3.

[0039] Specifically, the above-mentioned float-type water level wave measurement device is implemented in the following manner:

[0040] S1. The work vessel will deploy a float-type water level and wave measurement device into the observation area.

[0041] S2. The Beidou-3 short message terminal based on precise single-point positioning receives the anchor chain release order from the remote monitoring center and sends it to the equipment cabinet. The equipment cabinet starts and controls the first motor and the second motor to rotate synchronously in the forward direction, driving the drum to rotate in the forward direction to release the anchor chain. After the anchor chain is completely released (so that the sinker 11 sinks to the bottom and the anchor chain 10 is in a slack state), the first motor and the second motor are de-energized and braked.

[0042] S3. The Beidou-3 short message terminal, based on precise single-point positioning, acquires high-precision real-time positioning information and transmits the information to the remote monitoring center. The remote monitoring center can calculate the time average of the vertical coordinates in the real-time positioning information to determine the water level. It can calculate the wave speed by changing the positioning information and remove gross errors. Then, it can integrate the speed once to obtain the displacement and remove the linear trend term of the displacement to obtain the wave displacement information. Then, based on the wave displacement information, it can deduce the values ​​of wave elements, namely wave height, wave period, and wave direction.

[0043] S4. After the observation is completed, the Beidou-3 short message terminal based on precise single-point positioning receives the anchor chain recovery order from the remote monitoring center and sends it to the equipment cabinet. The equipment cabinet starts and controls the first motor and the second motor to reverse synchronously, driving the drum to reverse and recover the anchor chain. After the anchor chain is completely recovered, the first motor and the second motor are powered off and braked.

[0044] S5. The work vessel returns to the observation area and retrieves the float-type water level and wave measurement device based on the positioning information.

[0045] The above specific embodiments are used to explain and illustrate the present utility model, and are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made to the present utility model within the spirit and protection scope of the claims shall fall within the protection scope of the present utility model.
