[0015] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0016] The embodiment of this application is as follows:

[0017] Please see Figure 1-2 , Figure 1 This is a schematic diagram of the overall structure of a furnace flame monitoring device according to this utility model. Figure 2 This is a schematic diagram of the initial positioning component of this utility model.

[0018] This utility model provides a furnace flame monitoring device, including a mounting plate 101, a base plate 102, and a flame monitor 103, as well as a support device. The support device includes a sliding seat 104, an adjusting block 105, a moving block 106, a locking rod 107, a preliminary positioning component, and a sliding component. The preliminary positioning component includes a first positioning rod 110 and a second positioning rod 111. The sliding component includes a transverse toothed block 112, a mounting shaft 113, an adjusting gear 114, a rotating component, and a stop component. The rotating component includes a rotating rod 115 and a gripping rod 116. The stop component includes a stop plate 117 and a locking block 118. The aforementioned solution solves the problem that conventional fixing methods are not convenient for adjusting the position of the fixing structure according to the length or size of the furnace flame monitoring device, resulting in poor support and fixing effect and potential safety hazards in long-term use. The aforementioned solution can be used in furnace flame monitoring scenarios.

[0019] In this embodiment, the sliding component drives the movement of the adjusting block 105 and the sliding seat 104, enabling the sliding seat 104 to be adjusted to a suitable support position according to the length of the flame monitor 103. This facilitates the locking rod 107 in locking the flame monitor 103, thereby improving the support and fixation effect of the flame monitor 103.

[0020] The base plate 102 has a sliding groove 108. The adjusting block 105 is slidably mounted on the base plate 102 and located within the sliding groove 108. The sliding seat 104 is fixedly mounted on the adjusting block 105. The sliding seat 104 also has a moving groove 109. The moving block 106 is slidably mounted on the sliding seat 104 and located within the moving groove 109. The locking rod 107 is fixedly mounted on the moving block 106. The initial positioning component is located on the base plate 102. The sliding component is located on the base plate 102. The flame monitor 103 is model HRNTV-V1. The sliding seat 104 has a flat plate structure. The adjusting block 105 is located on the sliding seat 108. At the bottom of the 4, the moving blocks 106 are located on the left and right sides of the sliding seat 104. The locking rod 107 has an arc-shaped structure and a threaded hole at its top. After the flame monitor 103 is initially positioned by the initial positioning component, the flame monitor 103 is slid into the mounting plate 101. Then, the adjusting block 105 and the sliding seat 104 are slid to a position suitable for the length of the flame monitor 103 by the sliding component. The moving blocks 106 are moved towards each other, so that the locking rods 107 are brought closer together. The locking rods 107 are locked by screws, thus completing the fixation of the flame monitor 103 and improving the support and fixation effect of the flame monitor 103.

[0021] Secondly, the first positioning rod 110 and the second positioning rod 111 are respectively rotatably mounted on both sides of the base plate 102. The first positioning rod 110 and the second positioning rod 111 are both transverse T-shaped structures. The height of the first positioning rod 110 is less than the height of the second positioning rod 111. By setting the first positioning rod 110 and the second positioning rod 111, it is convenient to perform preliminary positioning of the flame monitor 103.

[0022] Furthermore, the transverse gear block 112 is fixedly mounted on the sliding seat 104; the mounting shaft 113 is rotatably mounted on the base plate 102 via the rotating member; the adjusting gear 114 is fixedly mounted on the mounting shaft 113 and meshes with the transverse gear block 112; the stop member is disposed on the base plate 102; the transverse gear block 112 is fixed to the bottom of the sliding seat 104 by bolts; the mounting shaft 113 is rotatably engaged with the base plate 102 via bearings; the adjusting gear 114 is located below the transverse gear block 112; the stop member can restrict the rotation of the mounting shaft 113; the rotating member can drive the mounting shaft 113 to rotate; and the mounting shaft 113, through the meshing transmission of the adjusting gear 114 and the transverse gear block 112, drives the sliding seat 104 to move.

[0023] Furthermore, the rotating rod 115 is fixedly mounted on the mounting shaft 113; the gripping rod 116 is rotatably mounted on the rotating rod 115, the rotating rod 115 is welded to the end of the mounting shaft 113, and the axis of the gripping rod 116 coincides with that of the mounting shaft 113. By gripping the gripping rod 116, it is easy to drive the rotating rod 115 to rotate, thereby driving the mounting shaft 113 to rotate.

[0024] Finally, the stop plate 117 is fixedly installed on the mounting shaft 113. The stop plate 117 is provided with multiple sets of slots 119. The bottom plate 102 is also provided with a mounting groove 120 on one side. The locking block 118 is slidably installed on the bottom plate 102 and located in the mounting groove 120. At the same time, the locking block 118 is close to the stop plate 117. The stop plate 117 has a disc structure. The slots 119 are circumferentially arranged on the outer wall of the stop plate 117. The thickness of the locking block 118 is equal to the width of the slot 119. By engaging the locking block 118 with the slot 119, the rotation of the mounting shaft 113 can be restricted, thereby completing the fixation of the sliding seat 104.

[0025] In this embodiment, when installing the flame monitor 103, the mounting plate 101 is first fixed to the outer surface of the furnace. The flame monitor 103 is then placed on the first positioning rod 110 and the second positioning rod 111, thus initially positioning the flame monitor 103. Subsequently, the flame monitor 103 is pushed in the opposite direction of the mounting plate 101, causing its end to pass through the mounting plate 101 and enter the furnace. Then, the position of the sliding seat 104 is adjusted according to the length of the flame monitor 103. By holding the gripping rod 116, the rotating rod 115 is rotated, which in turn rotates the mounting shaft 113. Through the meshing transmission of the adjusting gear 114 and the transverse gear block 112, the sliding seat 104 moves away from the mounting plate 101. When the sliding seat 104 moves to a suitable position, the sliding block 118 slides, so that the locking block 118 engages with the locking groove 119 on the stop plate 117, thus fixing the position of the sliding seat 104. By pushing the moving blocks 106 on both sides to move towards each other, the two sets of locking rods 107 move closer to each other and clamp the flame monitor 103. Then, the two sets of locking rods 107 are locked with screws, thus fixing the flame monitor 103. The sliding assembly drives the movement of the adjusting block 105 and the sliding seat 104, so that the sliding seat 104 can be adjusted to a suitable support position according to the length of the flame monitor 103, thereby facilitating the locking rods 107 to lock the flame monitor 103 and improving the support and fixing effect of the flame monitor 103.
