Description

Technical Field

[0001] The invention relates to a retractable and automatically balanced depth sounder fixing device, belonging to the technical field of surveying and mapping. Background Art

[0002] In the work of measuring underwater topography, the commonly used surveying instrument is the depth sounder. The conventional installation method of the depth sounder is to install it on the side of the ship or the bottom of the ship, but this method has the following problems: 1. Although it can ensure that the depth sounder is always underwater when installed on the bottom of the ship, the installation on the bottom of the ship is time-consuming and laborious, and during navigation, underwater obstacles are unknown, which can easily cause damage to the depth sounder. 2. When installed on the side of the ship, when the ship turns, the depth sounder is easy to be exposed to the water surface, resulting in inaccurate measurement data or data loss. In addition, the depth sounder is fixed on one side of the ship's side, resulting in a single-sided counterweight, which makes the hull unbalanced. When turning to the side of the counterweight, once the speed is fast, there is a risk of capsizing. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] Example 1

[0029] A retractable and automatically balanced depth sounder fixture, such as Figure 1 and 2As shown, it includes a telescopic balance pole 1 that can be extended and retracted, and the telescopic balance pole 1 is fixed on the hull 10 through a fixing mechanism 6, and a first counterweight 7 and a second counterweight 15 are hung on both ends of the telescopic balance pole 1 respectively, an electronic tube level 2 is arranged above the middle of the telescopic balance pole 1, and a winch 5 is arranged below the middle of the telescopic balance pole 1, and the winch 5 is connected to a depth sounder 9 through a steel cable 8, and the depth sounder 9 is located between the first counterweight 7 and the hull 10.

[0030] Furthermore, it also includes a central signal controller 3, which is electrically connected to the telescopic balance pole 1, the electron tube level 2 and the winch 5. The electron tube level 2 is used to detect the horizontality signal of the telescopic balance pole 1 and transmit the signal to the central signal controller 3. The central signal controller 3 can control the telescopic balance pole 1 to extend and retract according to the signal detected by the electron tube level 2, and control the winch 5 to rotate, and then control the depth sounder 9 to rise and fall.

[0031] Furthermore, it also includes a power supply 4, which is located above the hull 10 and is used to supply power to the entire fixing device.

[0032] Furthermore, the fixing mechanism 6 includes a spring 11, a ring buckle sleeve 12, a positioning bolt 13 and a clamping bolt 14. One end of the spring 11 is connected to the ring buckle sleeve 12, and the other end is connected to the clamping bolt 14. The positioning bolt 13 is located on the side of the ring buckle sleeve 12 away from the spring 11. The ring buckle sleeve 12 is sleeved on the telescopic balance bar 1, and the clamping bolt 14 is fixed on the hull 10. By tightening the positioning bolt 13, the ring buckle sleeve 12 is tightly sleeved on the telescopic balance bar 1, so that the telescopic balance bar 1 is fixedly connected to the fixing mechanism 6. By tightening the clamping bolt 14 inwardly, the fixing mechanism 6 is tightly fixed to the hull 10, and the telescopic balance bar 1 is elastically connected to the hull 10 through the spring 10, which plays a buffering and protective role on the telescopic balance bar 1 and the components connected to the telescopic balance bar 1.

[0033] Furthermore, there are two fixing mechanisms 6 , and the two fixing mechanisms 6 are connected above both sides of the hull 10 .

[0034] Further, one end of the steel cable 8 is fixedly connected to the depth sounder 9, and the other end passes through the bottom of the telescopic balance pole 1 and is wound on the winch 5. The depth sounder 9 can be controlled to rise and fall by rotating the winch 5. Optionally, the steel cable 8 has a diameter of 2 mm and a total length of 12 meters.

[0035] Optionally, the sum of the weight of the first counterweight 7 and the weight of the depth sounder 9 is equal to the weight of the second counterweight 15, thereby achieving balance of the entire fixing device.

[0036] Optionally, the telescopic balance pole 1 is made of aluminum alloy and can be extended. The maximum length of the telescopic balance pole 1 after overall extension is 6 meters, the middle non-retractable section is 3 meters, and the lengths of the retractable sections at both ends are 1.5 meters each.

[0037] Optionally, the overall height of the fixing mechanism 6 is 40 cm, the diameter of the buckle sleeve is 10 cm, the diameter of the spring 11 is 10 cm, and the natural length of the spring 11 is 20 cm.

[0038] Optionally, there is a tube in the electron tube level 2, and there is a horizontal bubble in the tube. When the electron tube level 2 itself is in a horizontal state, the horizontal bubble is located in the middle of the tube. When the electron tube level 2 tilts to one side, the horizontal bubble moves in the opposite direction.

[0039] The working principle of the present invention is as follows: a first counterweight 7 and a second counterweight 15 are suspended on both sides of a telescopic balancing rod 1. In an unloaded state, the weight of the first counterweight 7 + the weight of a depth sounder = the weight of the second counterweight 15. A depth sounder 9 is suspended on the side where depth measurement is required. The depth sounder 9 is connected to a steel cable 8 with a hook. The effect achieved is that the weight of the second counterweight 15 on one side is equal to the weight of the first counterweight 7 + the weight of the depth sounder 9 on the other side, thereby achieving balance.

[0040] When the ship is ready to start sounding, the level bubble of the electron tube level 2 is basically in the middle of the horizontal position because the second counterweight 15 on one side is balanced with the first counterweight 7 + depth sounder 9 on the other side. When the ship starts to move forward, the ship tilts to one side, and the level bubble in the tube of the electron tube level 2 will tilt in the opposite direction. At this time, the electron tube level 2 sends a signal to the central signal controller 3 requesting horizontal compensation. After receiving the signal, the central signal controller 3 controls the telescopic balance rod 1 to extend or shorten, and by changing the length of the force arm, the counterweight balance on both sides is achieved again, so that during the entire sounding process, the draft of the depth sounder 9 remains unchanged and does not leak out of the water, thereby ensuring the authenticity and validity of the sounding data and maintaining the stability and safety of navigation. When it is necessary to adjust the draft depth of the depth sounder 9 (there are obstacles, the water becomes shallower or deeper), the central signal controller 3 sends a signal to the winch 5, and the winch 5 changes the length of the steel cable 8 to change the draft depth of the depth sounder 9. When the ship turns during travel, if the depth sounder 9 leaves the water or the hull is in danger of capsizing, the depth sounder 9 sends a signal to the central signal controller 3, and the central signal controller 3 sends a signal to the winch 5, and the winch 5 changes the length of the steel cable 8 so that the depth sounder 9 is completely immersed in water, reducing the probability of the depth sounder 9 colliding with the riverbed and obstacles, and extending the life of the depth sounder 9. At the same time, the telescopic balance rod 1 is adjusted to extend or shorten, and the counterweight balance on both sides is achieved again by changing the length of the force arm to maintain the stability and safety of navigation.

[0041] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
