Referring to fig. 1, the present application provides a subsea mud temperature observation device 100, comprising: the tail end of the base 1 is used for being connected with an offshore drilling machine system; and the temperature probe module 20 is fixedly connected with the end part of the base 1, the temperature probe element 2 is arranged in the temperature probe module 20, the temperature probe element 2 is electrically connected with an external system through the base 1 or the temperature probe is powered by a built-in power supply device of the base 1. Wherein the base 1 can be driven by external force of the offshore drilling system to move the temperature probe module 20 to a seabed mud to-be-measured position, the temperature probe module 20 is configured such that the seabed mud is in contact with the temperature probe element 2.
When the submarine mud temperature observation device 100 according to the embodiment of the invention is used, the base 1 of the submarine mud temperature observation device 100 is connected with a ship or platform drilling machine system, the ship or platform drilling machine system provides power to push the whole submarine mud temperature observation device 100 into the submarine mud to a certain depth, namely, the position of the predicted temperature, and the temperature probe module 20 senses the temperature at the preset position for a period of time to obtain the in-situ temperature of the mud.
With continued reference to FIG. 1, in some embodiments, the thermometry probe module 20 may include: the element mounting seat 3, the temperature measuring probe element 2 is arranged on the element mounting seat 3, and the element mounting seat 3 is detachably connected with the end part of the base 1; and an end cap 33, the end cap 33 being detachably connected to an end of the component mounting seat 3 remote from the base 1. Wherein the end cap 33 is configured to: the cross-sectional diameter becomes gradually smaller in the axial direction away from the component mounting seat 3.
With the above arrangement, the end cap 33 is tapered in the cross-sectional diameter in the axial direction away from the component mounting seat 3, and it is understood that the end cap 33 may be constructed in a cone structure (as shown in fig. 2 and 3) or a cylinder structure (as shown in fig. 1) having a trapezoid cross-section.

In this embodiment, in some embodiments, the end cap 33 may be configured to wrap around the temperature probe element 2 during connection with the protective sleeve 31 to secure the temperature probe element 2. In particular, the wrapping extrusion is understood to mean that the central through hole of the end cap 33 for the passage of the temperature probe element 2 can be formed with a constriction so that the end cap 33 can achieve a gradual clamping of the temperature probe element 2. It can be also understood that the hardness of the material of the end protecting cap 33 is greater than that of the protecting sleeve 31, so that the protecting sleeve 31 can be deformed by extrusion during the connection process of the end protecting cap 33 and the protecting sleeve 31, so as to clamp the temperature measuring probe element 2 gradually.

In this embodiment, if the seabed mud temperature observation device 100 detects the seabed mud temperature of a harder stratum, the detection head of the temperature measurement probe element 2 is located in the end protection cap 33, so that the temperature sensing observation is performed after the soil or sand is squeezed into the end protection cap 33, the problem that the temperature measurement probe element 2 is relatively large in pressure bearing and easy to damage is effectively avoided, and the protection effect on the detection head of the temperature measurement probe element 2 is achieved. In addition, the end protective cap 33 is configured such that the end is formed in a tip structure, which further reduces resistance, so that the subsea mud temperature observation device 100 is more easily lowered into place, ensuring the accuracy of the detection position of the detection head of the temperature probe element 2.
In some embodiments, the end cap 33 may be configured to be threaded or fixedly attached to the protective sleeve 31 by fasteners to facilitate removal and attachment of the end cap 33.

In some embodiments, the mud temperature probe compartment 21 is provided with a plurality of spaced along the periphery of the element mount 3. By the arrangement, the temperature measuring elements 211 in the mud temperature probe cabins 21 can detect the temperature of the same layer of seabed mud at the same time, so that the accuracy of temperature detection is further improved, and the influence on the measurement result due to the damage of one temperature measuring element 211 is avoided.

In this application, the threaded sleeve 32 may be further configured to be capable of wrapping and pressing the protection sleeve 31 during the connection with the base 1, so as to fix the protection sleeve 31.
In this embodiment, the fact that the sleeve 32 can be wrapped and pressed against the protection sleeve 31 during the process of connecting the sleeve 32 with the base 1 is understood that the central through hole of the sleeve 32 for the protection sleeve 31 to pass through may be formed with a shrinkage opening, so that the sleeve 32 can realize gradual clamping of the protection sleeve 31. It can also be understood that the hardness of the material of the threaded sleeve 32 is greater than that of the base 1, so that the base 1 can be deformed by extrusion during the connection process of the threaded sleeve 32 and the base 1, so as to clamp the protection sleeve 31 gradually. It is of course also understood that the end of the base 1 is formed with gripping jaws which, in cooperation with the inside of the threaded sleeve 32, are able to achieve a gradual tightening, so as to grip the protection sleeve 31 gradually.
