[0002] In order to ensure safety during the operation of the oil platform, the flame detectors installed in the oil platform need to be monitored regularly to determine whether they have the ability to quickly identify flames. Therefore, a flame test lamp will be used for testing. During the test of the flame test lamp, people need to use a ladder to climb to the front of the flame detector, and then face the flame detector for it to respond. Due to the test conditions on site, the location of the flame detector will be relatively remote, in the corners of various tanks.

[0003] Therefore, a UV flame detector test device in the prior art has a publication number of CN216623470U. When in use, the fixing seat is held and the movable rod is pressed to move the L-shaped block out from the inside of the limiting groove. At this time, the connecting block is pulled upward, and the connecting block drives the UV lamp to move upward, and the telescopic rod is stretched at the same time. Then the latch rod is pushed inward to compress the first spring, and the gear is separated from the tooth groove. At this time, the UV lamp is rotated at the end of the connecting block to adjust the angle of the UV lamp and the connecting block, and then the latch rod is released. At this time, the first spring is stretched, so that the gear enters the tooth groove for clamping and fixing.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] like Figure 1-4As shown, a monitoring probe fixing device includes a flame test lamp 2 and a telescopic rod 1. The telescopic rod 1 can be a common electric telescopic rod on the market. The flame test lamp 2 can be raised by extending the telescopic rod 1. The flame test lamp 2 can be detachably installed on the telescopic end of the telescopic rod 1, and an adjustment mechanism is installed on the end surface of the cylinder body of the telescopic rod 1. The adjustment mechanism includes a fixed seat 4, and an intermediate seat 8 is rotatably connected to the upper surface of the fixed seat 4. A movable seat 3 for connecting the cylinder body part of the telescopic rod 1 is rotatably connected to the upper surface of the intermediate seat 8. A worm gear ring 9 is fixedly connected to the fixed seat 4 and sleeved on the bottom surface of the intermediate seat 8. A worm gear block 11 rotatably connected to the intermediate seat 8 is fixedly connected to one side of the movable seat 3. The intermediate seat 8 is rotatably connected to the worm gear rings 9 that are respectively connected to the worm gear rings 9. The first worm 10 and the second worm 12 are meshedly connected to the ring 9 and the worm gear block 11. The first worm 10 drives the meshed worm ring 9 to rotate, so that the fixed seat 4 and the intermediate seat 8 can rotate relative to each other. In addition, the second worm 12 drives the worm gear block 11 to rotate, so that the movable seat 3 can rotate and swing around the center line of the worm gear block 11 as the center. After the flame test lamp 2 is raised to a specified height, the telescopic rod 1 is driven to swing to a horizontal direction by the movable seat 3, and the position of the flame test lamp 2 is adjusted by extending the telescopic rod 1. After reaching a certain height, the flame test lamp 2 can be extended in the horizontal direction, and the fixed seat 4 is rotated to drag the intermediate seat 8 to rotate, thereby expanding the test range of the flame probe.

[0023] In order to increase the height that the flame test lamp 2 can reach: the opposite sides of the movable seat 3 and the fixed seat 4 are fixedly connected with the plug-in tube 5, and the movable seat 3 and the fixed seat 4 are slidably connected with two sockets 6 that penetrate the plug-in tube 5 and are symmetrically distributed. The side of the socket 6 is provided with a columnar protrusion that is inserted into the plug-in tube 5. The plug-in tube 5 on the movable seat 3 is used to be plugged with the cylinder part of the telescopic rod 1, and the plug-in tube 5 on the fixed seat 4 is used to be plugged with the telescopic end part of the telescopic rod 1. The columnar protrusion on the socket 6 is plugged with the telescopic rod 1. The movable seat 3 and the fixed seat 4 are rotatably connected with a screw threadedly connected to the socket 6 7, and the screw rod 7 is driven by a motor (not marked in the figure). Specifically, another telescopic rod 1 is selected, and the telescopic end of the other telescopic rod 1 is inserted into the plug tube 5 at the bottom of the fixed seat 4, and then the motor is used to drive the screw rod 7 to rotate, so that the socket 6 approaches the plug tube 5 until the columnar protrusion on the socket 6 is inserted into the plug tube 5 and the telescopic rod 1 or the cylinder part in the plug tube 5. The additional telescopic rod 1 can be extended to increase the rising height of the flame test lamp 2. Similarly, when the height needs to be continuously increased, it is only necessary to install the adjustment mechanism and the telescopic rod 1 again.

[0024] In order to drive the first worm 10 and the second worm 12 to rotate: one end of the first worm 10 extends outward through the intermediate seat 8 and is fixedly connected to a rotating bevel gear 18, the intermediate seat 8 is fixedly connected to an electric push rod 16, and the telescopic end of the electric push rod 16 is provided with a single-sided bevel gear 17 driven by a motor and used for meshing with the rotating bevel gear 18. The intermediate seat 8 is rotatably connected to two sprockets 14 driven by a chain and respectively installed on the second worm 12 and the intermediate seat 8, one of the sprockets 14 end faces is fixedly connected to a spur gear 13, and the intermediate seat 8 is also rotatably connected to a double-sided bevel gear 15, one side of which is meshed with the spur gear 13 and the other side is used to mesh with the single-sided bevel gear 17. As shown in the figure, the telescopic end of the electric push rod 16 is also fixed with a motor (Figure The electric push rod 16 is extended and retracted to realize the reciprocating movement of the single-sided bevel gear 17 at its extension end between the rotating bevel gear 18 and the double-sided bevel gear 15. In addition, one of the two tooth surfaces of the double-sided bevel gear 15 in this scheme is a spur tooth surface meshing with the spur gear 13, and the other is a helical tooth surface meshing with the single-sided bevel gear 17. When the single-sided bevel gear 17 is meshed with the rotating bevel gear 18, the single-sided bevel gear 17 drives the rotating bevel gear 18 to rotate, thereby realizing the rotation of the first worm 10. When the single-sided bevel gear 17 is meshed with the double-sided bevel gear 15, the single-sided bevel gear 17 drives the double-sided bevel gear 15 to rotate, thereby realizing the spur gear 13 driving the corresponding sprocket 14 to rotate. Under the transmission action of the chain, the other sprocket 14 drives the second worm 12 to rotate.

[0025] In addition, in actual use, a control cable is led out from the telescopic rod 1, the motor, the electric push rod 16 and the flame test lamp 2 to the bottom respectively, and an explosion-proof button box is installed at the bottom. The operation of the electrical equipment can be remotely controlled through the button box to meet the explosion-proof use requirements.

[0026] Working principle: according to the installation height of the flame probe and the maximum distance that the telescopic rod 1 can be extended, multiple telescopic rods 1 are selected, and an adjustment mechanism is configured at the bottom of the cylinder of each telescopic rod 1. The adjustment mechanism is assembled with the telescopic rod 1, and the flame test lamp 2 is raised to a certain height by extending the telescopic rod 1 to detect the flame probe. When the flame probe needs to be tested at different positions at a fixed height, in the adjustment mechanism close to the flame test lamp 2, when the electric push rod 16 is extended to realize the meshing of the single-sided bevel gear 17 and the double-sided bevel gear 15, the single-sided bevel gear 17 drives the double-sided bevel gear 15 to rotate, thereby realizing the rotation of the spur gear 13 The corresponding sprocket 14 is driven to rotate. Under the transmission action of the chain, another sprocket 14 drives the second worm 12 to rotate. The worm wheel block 11 is driven to rotate by the second worm 12, so that the movable seat 3 can rotate and swing with the center line of the worm wheel block 11 as the center. After the flame test lamp 2 is raised to a specified height, the telescopic rod 1 is driven to swing to a horizontal direction by the movable seat 3, and then the position of the flame test lamp 2 is adjusted by extending the telescopic rod 1. After reaching a certain height, the flame test lamp 2 can be extended in a horizontal direction, and the fixed seat 4 is used to rotate and drag the middle seat 8 to rotate, thereby expanding the test range of the flame probe.
