DETAILED DESCRIPTION

[0028] In order to make the above objectives, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0029] In the following description, a lot of specific details are set forth in order to give a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the concept of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0030] Secondly, "one embodiment" or "embodiment" referred to herein means that specific features, structures or characteristics can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an embodiment that is separate or alternative to other embodiments.

[0031] Embodiment 1, referring to FIG. 1 to FIG. 3, is the first embodiment of the present application, which provides a high-temperature steam pipeline temperature measuring point device, comprising a conveying mechanism 100, which comprises a steam pipeline 101 and a sleeve 102 fixed on the steam pipeline 101; in this embodiment, the sleeve 102 is welded on the outer wall surface of the steam pipeline 101, and the sleeve 102 and the steam pipeline 101 are in communication.

[0032] A cutoff mechanism 200, which comprises a valve body 201 fixed on the top end of the sleeve 102 and a blocking piece 202 fixed in the valve body 201; in this embodiment, the blocking piece 202 can control the opening and closing of the internal passage of the valve body 201.

[0033] A plug sleeve 300 fixed on the top end of the valve body 201; a temperature sensing probe 400 slidingly arranged on the inner wall of the plug sleeve 300; in this embodiment, the temperature sensing probe 400 can detect temperature, and the end of the temperature sensing probe 400 can be sealed by the plug sleeve 300 after being inserted into the plug sleeve 300.

[0034] It should be noted that the valve body 201 comprises a shell 201a fixed on the top end of the sleeve 102, a transverse passage 201b and a longitudinal passage 201c arranged in the shell 201a, a communication gap 201d connected with the transverse passage 201b and the longitudinal passage 201c, and a gas vent 201e arranged on the shell 201a; in this embodiment, the shell 201a is provided with flange structures at both ends, which can be connected with the sleeve 102 and the plug sleeve 300, the transverse passage 201b and the longitudinal passage 201c are arranged vertically and in communication with each other, the communication gap 201d is arranged near the plug sleeve 300, and the communication gap 201d is arranged near the side where the gas vent 201e is located, and the gas vent 201e and the transverse passage 201b are in communication with each other.

[0035] It should be noted that the blocking piece 202 includes a threaded sleeve 202a fixedly arranged in the shell 201a, a threaded rod 202b threadedly connected to the inner wall of the threaded sleeve 202a, and a rotating disc 202c fixedly arranged at the end of the threaded rod 202b. One end of the threaded rod 202b is fixedly installed with a blocking plug 202d. In the embodiment, the blocking plug 202d is slidingly arranged in the interior of the transverse channel 201b. When the blocking plug 202d is located at the position where the transverse channel 201b and the longitudinal channel 201c are communicated, the longitudinal channel 201c can be cut off. The end of the blocking plug 202d close to the threaded rod 202b is chamfered, and the communication gap 201d has a triangular structure. When the blocking plug 202d is located at the position where the transverse channel 201b and the longitudinal channel 201c are communicated, the transverse channel 201b and the longitudinal channel 201c are communicated through the communication gap 201d. When the blocking plug 202d moves in the direction of the air vent 201e, the blocking plug 202d covers the communication gap 201d after sliding into the transverse channel 201b, thereby completing the blocking of the end of the transverse channel 201b close to the air vent 201e.

[0036] When the temperature sensing probe 400 is inserted into the insertion sleeve 300, the gas in the insertion sleeve 300 can be extruded into the communication gap 201d through the end of the temperature sensing probe 400, discharged from the air vent 201e after passing through the transverse channel 201b, thereby facilitating the insertion of the temperature sensing probe 400. After the end of the temperature sensing probe 400 contacts the blocking plug 202d, the rotating disc 202c is rotated to rotate the threaded rod 202b, thereby sliding the blocking plug 202d to open the longitudinal channel 201c. Since the blocking plug 202d is dislocated from the communication gap 201d after sliding, the steam cannot leak from the air vent 201e through the communication gap 201d, thereby avoiding safety hazards. The temperature sensing probe 400 is inserted into the sleeve 102 until the end of the temperature sensing probe 400 enters the interior of the steam pipe 101, thereby measuring the temperature inside the high-temperature steam pipe. At this time, the end of the blocking plug 202d is abutted against the insertion position of the temperature sensing probe 400 by rotating the threaded rod 202b, thereby fixing the temperature sensing probe 400.

[0037] When the temperature sensing probe 400 needs to be removed after measurement, the temperature sensing probe 400 is lifted to a suitable position, and then the longitudinal channel 201c is blocked and cut off by the blocking plug 202d, thereby avoiding the leakage of steam. Subsequently, the temperature sensing probe 400 is pulled outwards. When the temperature sensing probe 400 is pulled out, the external gas can enter the transverse channel 201b through the air vent 201e and enter the longitudinal channel 201c through the communication gap 201d, thereby facilitating the pulling out of the temperature sensing probe 400 from the interior of the sleeve 102.

[0038] Embodiment 2, with reference to FIGS. 1-7, is a second embodiment of the present application, which is different from the previous embodiment in that it further comprises a positioning mechanism 500 fixed to the outer wall of the temperature sensing probe 400, and a clamping mechanism 600 fixed to the outer wall of the shell 201a; the positioning mechanism 500 comprises a connecting piece 501 provided on the outer wall of the temperature sensing probe 400, and a locking piece 502 slidingly provided in the connecting piece 501; the clamping mechanism 600 comprises a support piece 601 fixed to the outer wall of the shell 201a, and a first clamping piece 602 and a second clamping piece 603 fixed to the support piece 601; the cutoff mechanism 200 further comprises a limiting piece 203 slidingly provided on the outer wall of the shell 201a.

[0039] Specifically, the connecting piece 501 comprises a connecting frame 501a, and a guide groove 501b provided on the connecting frame 501a, and further comprises a buckle cap 501c provided on the connecting frame 501a, and a fixing bolt 501d connected between the buckle cap 501c and the connecting frame 501a; in this embodiment, the buckle cap 501c and the connecting frame 501a are connected by the fixing bolt 501d, which facilitates the installation and disassembly between the connecting frame 501a and the temperature sensing probe 400.

[0040] Further, the locking piece 502 comprises a clamping frame 502a slidingly provided in the connecting frame 501a, and a sliding frame 502b slidingly provided in the clamping frame 502a, and a clamping block 502c fixedly installed at the end of the sliding frame 502b, and further comprises a spring 502d provided in the sliding frame 502b; in this embodiment, the sliding frame 502b can slide in the clamping frame 502a, the two ends of the spring 502d are connected with the sliding frame 502b and the clamping frame 502a respectively, the end of the clamping frame 502a away from the clamping block 502c is a slope, the end of the clamping block 502c away from the clamping frame 502a is a slope, and the surfaces of the two ends away from each other are in a mutually parallel state.

[0041] Further, the outer wall of the clamping frame 502a is fixedly installed with a first push column 502a-1; the outer wall of the clamping block 502c is fixedly installed with a second push column 502c-1; in this embodiment, the outer walls of the first push column 502a-1 and the second push column 502c-1 are slidingly connected with the inner wall of the guide groove 501b.

[0042] Preferably, the limiting piece 203 comprises a rotating sleeve 203a rotatingly arranged on the outer wall of the threaded rod 202b, a limiting sleeve 203b fixedly arranged on the outer wall of the rotating sleeve 203a, a first limiting rod 203c fixedly arranged on the top end of the limiting sleeve 203b, and a second limiting rod 203d fixedly arranged on the top end of the limiting sleeve 203b. In the embodiment, the limiting sleeve 203b can slide horizontally on the outer wall of the shell 201a. When the threaded rod 202b rotates, the limiting sleeve 203b will slide horizontally along with the displacement of the threaded rod 202b. The first limiting rod 203c is arranged close to the first push column 502a-1, and the second limiting rod 203d is arranged close to the second push column 502c-1. The first push column 502a-1 and the second push column 502c-1 are arranged between the first limiting rod 203c and the second limiting rod 203d.

[0043] Preferably, the first clamping piece 602 comprises a first fixed frame 602a fixedly arranged on the supporting piece 601, and a first clamping rack 602b fixedly arranged on the top of the first fixed frame 602a. It should be noted that the second clamping piece 603 comprises a second fixed frame 603a fixedly arranged on the supporting piece 601, and a second clamping rack 603b fixedly arranged on the top of the second fixed frame 603a. The tooth grooves on the first clamping rack 602b and the tooth grooves on the second clamping rack 603b are opposite to each other. In the embodiment, the outer walls of the first clamping rack 602b and the second clamping rack 603b are slidingly connected with the inner wall of the connecting frame 501a, so as to limit the connecting frame 501a, increase the stability of the connecting frame 501a, and further increase the fixing effect on the temperature sensing probe 400.

[0044] Preferably, the top of the clamping frame 502a is fixedly installed with a first extrusion block 502a-3, and the top of the clamping block 502c is fixedly installed with a second extrusion block 502c-3. The first extrusion block 502a-3 and the second extrusion block 502c-3 are arranged to facilitate the user to extrude the clamping frame 502a and the clamping block 502c, and facilitate the compression of the spring 502d.

[0045] The remaining structures are the same as those in Embodiment 1.

[0046] In use, when the blocking plug 202d is in the state of cutting off the longitudinal channel 201c, the second limiting rod 203d and the second push column 502c-1 are in the state of abutting at this time, the locking member 502 is located close to the area where the first clamping member 602 is located, under the elastic force of the spring 502d, the clamping frame 502a can be clamped on the tooth groove of the first clamping rack 602b, when the blocking plug 202d is in the blocking state, the temperature sensing probe 400 can only be pulled out and cannot be inserted into the inside of the sleeve 102, so that the temperature sensing probe 400 can only be pulled out and cannot be inserted, which can avoid that the end of the temperature sensing probe 400 abuts against the blocking plug 202d to cause damage to the detection part after the temperature sensing probe 400 is stressed, when it is necessary to control the temperature sensing probe 400 to be inserted into the sleeve 300, it is necessary to squeeze the clamping frame 502a and the clamping block 502c, so that the spring 502d is compressed, so that the clamping frame 502a is separated from the clamping of the first clamping rack 602b, at this time, the insertion of the temperature sensing probe 400 can be controlled.

[0047] When the blocking plug 202d moves to the position close to the air vent 201e, the first limiting rod 203c pushes the first push column 502a-1, the first push column 502a-1 and the second push column 502c-1 slide in the inner wall of the guide groove 501b, so that the locking member 502 moves to the position close to the second clamping member 603, at this time, the first limiting rod 203c and the first push column 502a-1 are in the state of abutting, the clamping block 502c and the tooth groove on the second clamping rack 603b are in the state of clamping, at this time, the temperature sensing probe 400 can only be inserted into the sleeve 300 and cannot be pulled out, which can avoid that the pressure in the steam pipeline 101 pushes out the temperature sensing probe 400, if it is necessary to pull out the temperature sensing probe 400, it is necessary to squeeze the clamping frame 502a and the clamping block 502c, so that the spring 502d is compressed, so that the clamping block 502c is separated from the clamping of the second clamping rack 603b, at this time, the pulling out of the temperature sensing probe 400 can be controlled.

[0048] Embodiment 3, referring to FIGS. 1-8, is the third embodiment of the present application, which is different from the previous embodiment in that the support member 601 comprises a support seat 601a fixedly arranged on the outer wall of the shell 201a, and a support plate 601b fixedly arranged on the support seat 601a, the support plate 601b is provided with a notch 601c, and a limiting rod 601d is uniformly arranged on the notch 601c from bottom to top, in this embodiment, the support plate 601b is provided with two and is symmetrically arranged on the support seat 601a, the arrangement of the support plate 601b can limit the first limiting rod 203c and the second limiting rod 203d, and increase the strength of the first limiting rod 203c and the second limiting rod 203d.

[0049] Specifically, the end of the first push column 502a-1 is fixedly installed with a first right trapezoidal block 502a-2; the end of the second push column 502c-1 is fixedly installed with a second right trapezoidal block 502c-2. The side of the first right trapezoidal block 502a-2 close to the second right trapezoidal block 502c-2 is an inclined surface, the side of the second right trapezoidal block 502c-2 close to the first right trapezoidal block 502a-2 is an inclined surface, and the sides of the first right trapezoidal block 502a-2 and the second right trapezoidal block 502c-2 close to each other are in parallel state.

[0050] The rest of the structure is the same as that of Example 2.

[0051] When the blocking plug 202d is in the state of cutting off the longitudinal channel 201c, the second right-angled trapezoidal block 502c-2 is located at the side of the limiting strip 601d, and the limiting strip 601d cannot hinder the up-down sliding of the second right-angled trapezoidal block 502c-2 at this time. During the process of rotating the threaded rod 202b to move the blocking plug 202d from one end to the other end of the transverse channel 201b, the displacement of the threaded rod 202b will drive the displacement of the second limiting rod 203d. Under the elastic force of the spring 502d, the clamping frame 502a and the first clamping rack 602b are kept in the clamping state, the second limiting rod 203d and the second push column 502c-1 are kept in the abutting state, and the second right-angled trapezoidal block 502c-2 will produce a horizontal displacement. After the horizontal displacement, it will enter between the uniformly arranged limiting strips 601d, and the up-down sliding of the connecting frame 501a is limited by the limiting strips 601d, so as to keep the locking of the temperature sensing probe 400. With the increase of the displacement distance of the threaded rod 202b, the first limiting rod 203c will abut against the first push column 502a-1, push the locking piece 502 to slide, and the first right-angled trapezoidal block 502a-2 will slide into the uniformly arranged limiting strips 601d, and the up-down sliding of the connecting frame 501a is limited by the limiting strips 601d. Until the threaded rod 202b moves a certain distance, the clamping block 502c will abut against the second clamping rack 603b, and the threaded rod 202b continues to displace so that the first limiting rod 203c abuts against the first push column 502a-1, so that the spring 502d is compressed, and the first right-angled trapezoidal block 502a-2 slides out of the limiting strip 601d. At this time, the limiting of the limiting strip 601d is released, and the connecting frame 501a is limited by the clamping of the clamping block 502c and the second clamping rack 603b. When adjusting the position of the blocking piece 202, the temperature sensing probe 400 can be kept locked to avoid the phenomenon that the temperature sensing probe 400 is pushed out of the plug sleeve 300 by steam. Since the side of the first right-angled trapezoidal block 502a-2 close to the second right-angled trapezoidal block 502c-2 is an inclined surface, the side of the second right-angled trapezoidal block 502c-2 close to the first right-angled trapezoidal block 502a-2 is an inclined surface, and the side of the first right-angled trapezoidal block 502a-2 and the second right-angled trapezoidal block 502c-2 close to each other is in parallel state, the first right-angled trapezoidal block 502a-2 and the second right-angled trapezoidal block 502c-2 can keep larger area contact with the limiting strip 601d, and at the same time, the sliding between the clamping frame 502a and the sliding frame 502b is also ensured, which reduces the stroke required for the displacement of the threaded rod 202b to make the first right-angled trapezoidal block 502a-2 and the second right-angled trapezoidal block 502c-2 pass through the limiting strip 601d, and ensures that at least one of the first right-angled trapezoidal block 502a-2 and the second right-angled trapezoidal block 502c-2 can form effective limiting with the limiting strip 601d when passing through the limiting strip 601d, thereby improving the limiting effect on the connecting frame 501a.
