Description

Technical Field

[0001] The present invention relates to seawater The technical field of surface temperature measurement particularly relates to a device for measuring the shallow surface temperature of seawater while a ship is moving. Background Art

[0002] In the infrared characteristic measurement of ships, it is necessary to measure the water temperature of the shallow layer close to the water surface. Usually, the underwater temperature is collected on board by fixing the temperature sensor buoy with a cable and placing it in the water. When placing the sensor underwater to collect data, the buoy will rise and fall with the waves, especially when the ship is moving, it will sometimes leave the water surface, causing the depth of the temperature sensor to be unstable, affecting the accuracy of the measurement data. The buoy will move horizontally with the waves, and the towing rope and buoy will collide and hook with the hull and other objects, especially there is a possibility of collision and entanglement with the propeller, affecting driving safety. Therefore, it is necessary to design a ship-borne shallow surface temperature measurement device for seawater. Summary of the invention

[0003] The object of the present invention is to provide a device for measuring the shallow surface temperature of seawater while underway for use on a ship, so as to solve at least one problem existing in the background technology.

[0004] In order to achieve the above object, the present invention provides a device for measuring the shallow surface temperature of seawater while underway for use on a ship, characterized in that it comprises:

[0005] The shell is provided with a plurality of water holes penetrating the shell wall, and the shell is fixedly installed on the outside of the ship;

[0006] A buoy is placed in the shell and is able to be suspended on the water and float in the shell;

[0007] The temperature sensor is installed below the buoy and has a smaller radial dimension than the buoy. When the buoy contacts the inner wall of the shell, there is a gap between the temperature sensor and the inner wall of the buoy.

[0008] The collector is installed on board and connected with the temperature sensor signal.

[0009] Optionally, the device for measuring the shallow surface temperature of seawater while underway for use on a ship further comprises a protection rope, one end of which is connected to the buoy, and the other end of which is connected to the ship or a collector.

[0010] Optionally, the collector is connected to the temperature sensor via a cable signal.

[0011] Optionally, the cable is arranged in a spiral shape and surrounds the outside of the protection rope.

[0012] Optionally, the shell is in a cylindrical shape with both ends open.

[0013] Optionally, the housing is fixedly mounted on the chord via a fixing rod.

[0014] The above technical solution of the present invention has the following advantages:

[0015] The present invention provides a device for measuring the shallow surface temperature of seawater during movement, comprising a shell, a buoy, a temperature sensor and a collector. The shell is fixedly mounted on the outside of the ship's chord and moves synchronously with the hull. The buoy is placed in the shell, can be suspended on the water, and can float in the shell. The temperature sensor is installed below the buoy, and the radial size of the temperature sensor is smaller than that of the buoy. When the buoy contacts the inner wall of the shell, there is a gap between the temperature sensor and the inner wall of the buoy to avoid affecting the use of the temperature sensor. The collector is installed on the ship and connected to the temperature sensor signal to realize signal collection of the temperature sensor, so that the temperature sensor can always accurately measure the temperature of the shallow surface of seawater. The shell provides protection for the temperature sensor to avoid collision and hooking with the hull and other objects or collision and entanglement with the propeller.

[0016] The present invention provides a device for measuring the shallow surface temperature of seawater during movement, which also includes a protective rope, one end of which is connected to a buoy, and the other end is connected to the ship or a collector. The cable is arranged in a spiral shape and surrounds the outer side of the protective rope. It can prevent the temperature sensor from jumping out of the water, thereby achieving more accurate and reliable measurement of the shallow surface temperature of seawater. On the other hand, it also prevents the cable from being entangled with the protective rope. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figure 1 and Figure 2 As shown, the device for measuring the shallow surface temperature of seawater during movement provided by the embodiment of the present invention comprises a shell 1, a buoy 2, a temperature sensor 3 and a collector 4. Among them, the shell 1 is provided with a plurality of water holes 11 penetrating the shell wall, so that the seawater in the shell 1 is always connected with the external seawater, ensuring accurate temperature measurement, and filtering debris at the same time. The shell 1 is fixedly installed on the outside of the chord 100 and moves synchronously with the hull. The buoy 2 is placed in the shell 1, can be suspended on the water, and can float in the shell 1. The temperature sensor 3 is installed below the buoy 2, for example, installed below and in the middle of the buoy 2. The radial size of the temperature sensor 3 in the buoy 2 is smaller than that of the buoy 2. When the buoy 2 contacts the inner wall of the shell 1, the temperature sensor 3 is spaced from the inner wall of the buoy 2 to avoid affecting the use of the temperature sensor 3. The collector 4 is installed on the ship and connected to the temperature sensor 3 signal to realize the signal collection of the temperature sensor 3.

[0032] When in use, the housing 1 is installed on the outside of the chord 100, so that the lower part of the housing 1 (such as the lower half or the lower two-thirds of the housing, etc.) is located in the water, and at least a part is located on the water surface. The temperature sensor 3 is located in the housing 1 with the buoy 2 and can float in the water with the buoy 2, so that the temperature sensor 3 can always accurately measure the temperature of the shallow surface of the seawater. The housing 1 provides protection for the temperature sensor 3 to avoid collision and hooking with the hull and other objects or collision and entanglement with the propeller.

[0033] In one example, the device for measuring the shallow surface temperature of seawater while underway for use on a ship also includes a protective rope 6, one end of which is connected to the buoy 2, and the other end is connected to the ship or the collector 4, so as to further improve reliability and avoid loss of the temperature sensor 3.

[0034] In one example, the collector 4 and the temperature sensor 3 are connected by a cable 5. Not only is the signal transmission stable, but the temperature sensor 3 can also be further lost.

[0035] See also Figure 2 As shown, based on the embodiment with the cable 5 and the protection rope 6, in one example, the cable 5 is arranged in a spiral shape and surrounds the outer side of the protection rope 6, that is, the cable 5 is arranged in a spring shape, but because the cable 5 for signal transmission is generally not very hard (selected as a requirement not to affect the floating of the temperature sensor on the surface of the sea), it has a certain elasticity while not affecting the floating of the temperature sensor 3 with the buoy 2, avoiding the temperature sensor from jumping out of the water, and achieving more accurate and reliable seawater shallow surface temperature measurement. On the other hand, it also avoids the cable 5 and the protection rope 6 from getting entangled.

[0036] In one example, the housing 1 is cylindrical with both ends open, and the smooth inner wall reduces collision damage to internal components. At the same time, the open-ended setting makes it easier to place and take out the internal parts, while increasing connectivity with seawater.

[0037] In one example, see Figure 1 As shown, the housing 1 is fixedly mounted on the chord 100 via a fixing rod 7, for example, it can be fixed by welding or the like.

[0038] In summary, the present invention provides a device for measuring the shallow surface temperature of seawater during movement, including a shell, a buoy, a temperature sensor and a collector. The shell is fixedly mounted on the outside of the chord and moves synchronously with the hull. The buoy is placed in the shell, can be suspended on the water, and can float in the shell. The temperature sensor is installed below the buoy, and the radial size of the temperature sensor is smaller than the buoy. When the buoy contacts the inner wall of the shell, there is a gap between the temperature sensor and the inner wall of the buoy to avoid affecting the use of the temperature sensor. The collector is installed on the ship and connected to the temperature sensor signal to realize signal collection of the temperature sensor, so that the temperature sensor can always accurately measure the temperature of the shallow surface of seawater. The shell provides protection for the temperature sensor to avoid collision and hooking with the hull and other objects or collision and entanglement with the propeller.

In the absence of a conflict of solutions, the various technical features mentioned in each embodiment can be combined in any manner to form other implementation methods that can be understood by those skilled in the art.
