[0001] The invention relates to the technical field of thermocouples, in particular to a thermocouple temperature sensor detection device. Background Art

[0002] Thermocouples are commonly used temperature measuring elements in temperature measuring instruments. They directly measure temperature and convert temperature signals into thermoelectric potential signals, which are then converted into the temperature of the measured medium through electrical instruments. Existing measuring devices cannot fix the detection device when detecting liquids and solids. They need to be manually held, which is cumbersome to operate. The depth of the detection device entering the water cannot be adjusted according to actual measurement needs, which reduces the detection efficiency of the device. Summary of the invention

[0003] In view of the shortcomings of the prior art, the present invention provides a thermocouple temperature sensor detection device, which solves the problem that the existing measuring device cannot fix the detection device when detecting liquids and solids, requires manual hand-held device, and the operation is cumbersome. In addition, the depth of the detection device entering the water can be adjusted according to actual measurement needs, the detection range is wider, and the detection efficiency of the device is improved.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a thermocouple temperature sensor detection device, including a wiring mechanism, a protective sleeve is fixedly connected to the bottom of the wiring mechanism, a thermocouple working end is arranged at the bottom of the protective sleeve, a lead-out wire sleeve is arranged on one side of the wiring mechanism, a floating device is sleeved on the outer side of the protective sleeve, a mounting sleeve is sleeved on the outer side of the protective sleeve at the bottom of the floating device, and a telescopic support is fixedly connected to the bottom of the mounting sleeve; the floating device includes a fixed sleeve, and a curved sleeve is evenly installed on the outer side of the fixed sleeve.

[0006] Preferably, the fixed sleeve is sleeved on the protective sleeve and fixedly connected to the protective sleeve, the floating balls and the curved brackets are staggered, and the floating balls are provided in multiple groups.

The floating ball is driven to tilt by a manual deflection wiring mechanism through a curved bracket. Since the flip baffle is subjected to horizontal buoyancy, an angle is formed between the water inlet at the bottom of the water inlet pipe and the flip baffle, and water can enter the floating ball from the gap between the water inlet and the flip baffle. When the water volume inside the floating ball reaches a certain level, the hand no longer deflects the wiring mechanism, and the wiring mechanism returns to the center under the action of buoyancy. At this time, the floating ball is reset and the flip baffle cooperates with the water inlet below the floating ball again to block the water inlet.

[0010] Preferably, the bottom of the limiting top plate is fixedly connected to the top of the floating ball, and the threaded rod is matched with the threaded sleeve.

[0011] Preferably, an extension rod is fixedly connected to the outer side of the limit support frame, and the bottom of the extension rod is fixedly connected to the limit side plate, the limit side plates are provided with two groups and are symmetrically installed, a sliding groove is opened on the side of the limit side plate close to the threaded sleeve, and a sliding block is symmetrically installed on the outer side of the threaded sleeve, and the end of the sliding block away from the threaded sleeve extends into the sliding groove on one side of the limit side plate, and the top of the rotating rod penetrates the floating ball and the limit top plate and is fixedly connected with a rotating disk, and the threaded rod is rotated inside the threaded sleeve to drive the threaded sleeve to slide down along the sliding groove on the limit side plate through the sliding block, so as to adjust the height of the shock absorbing block, and the position of the arc elastic plate can be adjusted according to actual needs. When the arc elastic plate is far away from the flip baffle, the larger the rotation range of the flip baffle is, the faster the water inlet speed is, thereby improving the working efficiency of the device.

[0012] The present invention provides a thermocouple temperature sensor detection device, which has the following beneficial effects:

[0013] (I) This thermocouple temperature sensor detection device, through the installation of the flip water inlet device and the floating device, uses the manual deflection wiring mechanism to drive the floating ball to tilt through the curved bracket. Since the flip baffle is subjected to horizontal buoyancy, the water inlet at the bottom of the water inlet pipe and the flip baffle form an angle, and water can enter the floating ball from the gap between the water inlet and the flip baffle. When the water volume inside the floating ball reaches a certain level, the hand no longer deflects the wiring mechanism, and the wiring mechanism returns to the center under the action of buoyancy. At this time, the floating ball is reset and the flip baffle cooperates with the water inlet below the floating ball again to block the water inlet. The depth of the detection device entering the water can be adjusted according to actual measurement needs, the detection range is wider, and the detection efficiency of the device is improved.

[0014] (ii) This thermocouple temperature sensor detection device, through the installation of a limit device, can rotate the rotating disk to drive the rotating rod to rotate, so that the arc-shaped elastic plate is located above the flip baffle. When the flip baffle rotates, it can only rotate to a position in contact with the upper arc-shaped elastic plate, thereby limiting the maximum value of the angle between the water inlet at the bottom of the water inlet pipe and the flip baffle. The water inlet speed can be limited to adjust the depth of the detection device entering the water and improve the accuracy.

[0015] (III) This thermocouple temperature sensor detection device, through the arrangement of a floating ball and a telescopic support, utilizes the buoyancy of the floating ball itself to make the portion above the floating device float on the water surface, while the working end of the thermocouple extends into the water to detect the water temperature. When the object to be detected is a solid, the telescopic support can be adjusted to extend. The detection device can be fixed when detecting liquids and solids, and no manual hand-held device is required, which is convenient to operate.

[0016] (IV) This thermocouple temperature sensor detection device, through the arrangement of a threaded sleeve and a threaded rod, utilizes the threaded rod to rotate inside the threaded sleeve, drives the threaded sleeve to slide down along the slide groove on the limiting side plate through the slider, and adjusts the height of the shock-absorbing block. The position of the arc-shaped elastic plate can be adjusted according to actual needs. When the arc-shaped elastic plate is far away from the flip baffle, the larger the range of rotation of the flip baffle, the faster the water inlet speed, thereby improving the working efficiency of the device.

The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0025] Embodiment 1

[0026] See also Figure 1-Figure 4 The present invention provides a technical solution: a thermocouple temperature sensor detection device, comprising a wiring mechanism 1, a protective sleeve 2 is fixedly connected to the bottom of the wiring mechanism 1, a thermocouple working end 3 is arranged at the bottom of the protective sleeve 2, a lead-out wire sleeve 4 is arranged on one side of the wiring mechanism 1, a floating device 5 is sleeved on the outer side of the protective sleeve 2, a mounting sleeve 6 is sleeved on the outer side of the protective sleeve 2 at the bottom of the floating device 5, and a telescopic support 7 is fixedly connected to the bottom of the mounting sleeve 6;

[0027] The floating device 5 includes a fixed sleeve 51, and curved brackets 52 are evenly installed on the outer side of the fixed sleeve 51. The end of the curved bracket 52 away from the fixed sleeve 51 is fixedly connected to an annular tube 53, and a floating ball 54 is arranged on the annular tube 53. Both sides of the floating ball 54 are connected to the annular tube 53. A flip water inlet device 55 is arranged on the inner bottom of the floating ball 54, and a limiting device 56 is fixedly connected to the inner top of the floating ball 54.

[0028] One end of the lead-out wire sleeve 4 is connected to the wiring mechanism 1 , the mounting sleeve 6 is fixedly connected to the protective sleeve 2 , and multiple groups of telescopic supports 7 are arranged and evenly distributed on the mounting sleeve 6 .

[0029] The fixed sleeve 51 is sleeved on the protective sleeve 2 and fixedly connected to the protective sleeve 2. The floating balls 54 and the curved brackets 52 are alternately arranged, and the floating balls 54 are arranged in multiple groups.

[0030] The flip water inlet device 55 includes a water inlet pipe 551, and a groove 552 is symmetrically opened on the outer side of the water inlet pipe 551. The inner wall of the groove 552 is fixedly connected to a limit block 553. A rotating rod 554 is arranged on one side of the limit block 553. A flip baffle 555 is fixedly connected to the outer side of the rotating rod 554. A hollow buoyancy ball 556 is arranged on the flip baffle 555.

[0031] The top of the water inlet pipe 551 is connected to the floating ball 54, and both ends of the rotating rod 554 are rotatably connected to the limit block 553 through a rotating seat. The outer side of the hollow buoyancy ball 556 is fixedly connected to the flip baffle 555. Four groups of hollow buoyancy balls 556 are arranged and evenly distributed on the flip baffle 555.

[0032] When in use, the detection device is placed in the water area to be detected. Due to the buoyancy of the floating ball 54 itself, the part above the floating device 5 floats on the water surface, and the working end 3 of the thermocouple is extended into the water to detect the water temperature. When the detected object is solid, the telescopic support 7 can be adjusted to extend. Through the arrangement of the floating ball and the telescopic support, the buoyancy of the floating ball itself is utilized to make the part above the floating device float on the water surface, and the working end of the thermocouple is extended into the water to detect the water temperature. When the detected object is solid, the telescopic support can be adjusted to extend. The detection device can be fixed when detecting liquids and solids, without the need for manual hand-held devices, and the operation is convenient.

[0033] When the device is put into water, the manually deflected wiring mechanism 1 drives the floating ball 54 to tilt through the curved bracket 52. Since the flip baffle 555 is subjected to horizontal buoyancy, an angle is formed between the water inlet at the bottom of the water inlet pipe 551 and the flip baffle 555, and water can enter the floating ball 54 from the gap between the water inlet and the flip baffle 555. When the water volume inside the floating ball 54 reaches a certain level, the hand no longer deflects the wiring mechanism 1, and the wiring mechanism 1 returns to the normal position under the action of buoyancy. At this time, the floating ball 54 is reset and the flip baffle 555 cooperates with the water inlet below the floating ball 54 again to block the water inlet. The installation of the driving device utilizes the manual deflection wiring mechanism to drive the floating ball to tilt through the curved bracket. Since the flip baffle is subjected to horizontal buoyancy, the water inlet at the bottom of the water inlet pipe and the flip baffle form an angle, and water can enter the floating ball from the gap between the water inlet and the flip baffle. When the water volume inside the floating ball reaches a certain level, the hand no longer deflects the wiring mechanism, and the wiring mechanism returns to the center under the buoyancy. At this time, the floating ball is reset and the flip baffle cooperates with the water inlet below the floating ball again to block the water inlet. The depth of the detection device entering the water can be adjusted according to actual measurement needs, the detection range is wider, and the detection efficiency of the device is improved.

A sliding block 5612 is symmetrically installed on the outer side of the threaded sleeve 567. The end of the sliding block 5612 away from the threaded sleeve 567 extends into the sliding groove on one side of the limiting side plate 5611. The top of the rotating rod 564 passes through the floating ball 54 and the limiting top plate 561 and is fixedly connected to a rotating disk 5613.

[0038] When in use, the rotating disk 5613 is rotated to drive the rotating rod 564 to rotate, and the threaded rod 565 is rotated inside the threaded sleeve 567, driving the threaded sleeve 567 to slide down along the slide groove on the limiting side plate 5611 through the slider 5612, and the height of the shock-absorbing block 568 is adjusted so that the arc elastic plate 569 is located above the flip baffle 555. When the flip baffle 555 rotates, it can only rotate to a position in contact with the upper arc elastic plate 569, limiting the maximum angle between the water inlet at the bottom of the water inlet pipe 551 and the flip baffle 555. The maximum value can be achieved by installing the limit device, and the rotating disk can be rotated to drive the rotating rod to rotate. The threaded rod rotates inside the threaded sleeve, driving the threaded sleeve to slide down along the slide groove on the limit side plate through the slider, and the height of the shock-absorbing block is adjusted so that the arc-shaped elastic plate is located above the flip baffle. When the flip baffle is rotated, it can only be rotated to the position in contact with the upper arc-shaped elastic plate, thereby limiting the maximum value of the angle between the water inlet at the bottom of the water inlet pipe and the flip baffle. The water inlet speed can be limited to adjust the depth of the detection device entering the water and improve the accuracy.
