DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0027] See also Figures 1 to 7 An embodiment of the present invention provides a smoke detection device, which includes a semicircular arc plate 1, a smoke sensor A2, a smoke sensor B2', a telescopic rod 5, a marking component 6 and an adjustment component 7.

[0028] In the embodiments of the present invention, please refer to Figure 1 、 Figure 2 and Figure 3 The inner wall of the semicircular plate 1 is equipped with multiple groups of annularly distributed and rotatably connected rollers 11, and multiple smoke sensors A2 are fixedly installed on one side of the inner wall of the semicircular plate 1. Two symmetrically distributed elastic corrugated steel plates 3 are fixedly installed on the semicircular plate 1, and a fixing block 31 is fixedly installed on the upper end of each elastic corrugated steel plate 3. The inner plate wall of the fixing block 31 is fixedly installed with a smoke sensor B2', and an adjustment component 7 for adjusting the angle of the smoke sensor B2' is installed on the semicircular plate 1;

[0029] The bottom of the semi-circular arc plate 1 is fixedly installed with an insertion rod 12, and the bottom of the insertion rod 12 is provided with a telescopic rod 5, and the telescopic rod 5 includes a sleeve 51, and a sliding rod 52 with a sliding connection is inserted in the sleeve 51, and the rod head of the sliding rod 52 extends out of the sleeve 51 and is fixedly installed with a sleeve tube 53, and the insertion rod 12 is inserted into the sleeve tube 53 and is slidably connected with the sleeve tube 53. A spring A4 is sleeved on the insertion rod 12, and one end of the spring A4 is fixedly connected to the outer ring wall of the semi-circular arc plate 1, and the other end of the spring A4 is fixedly connected to the upper end of the sleeve tube 53. A fixing screw A54 with a threaded connection and used to tighten the sliding rod 52 is installed on the sleeve 51.

[0030] It should be noted that when performing smoke leak detection on a pipeline, the staff adjusts the length of the telescopic rod 5 according to the installation height of the pipeline. Specifically, the sliding rod 52 is slid along the sleeve 51 to adjust the length of the sleeve 51 and the sliding rod 52. After the adjustment is completed, the fixing screw A54 is tightened to fix the sliding rod 52 on the sleeve 51.

[0031] Then, the elastic corrugated steel plate 3 is pulled outward by the adjustment component 7 to deflect it outward, and the roller 11 in the semicircular plate 1 is fitted against the pipe body in the lower half of the pipe. Thus, the smoke sensor A2 in the semicircular plate 1 can detect the pipe body below the pipe. Then, the adjustment component 7 is used to drive the elastic corrugated steel plate 3 to bend toward the inner circle of the pipe, so that the smoke sensor B2' on the fixed block 31 can fit against the pipe body above the pipe and perform smoke detection. Therefore, smoke detection can be carried out comprehensively around the pipe.

[0032] The staff member holds the sleeve 51 and pushes the semicircular plate 1 to make the roller 11 slide along the pipe. Therefore, the smoke sensor A2 and the smoke sensor B2' can detect smoke leaks in the pipe. When a smoke leak is detected in a certain place in the pipe, the smoke sensor A2 and the smoke sensor B2' will issue an early warning, and then the marking component 6 will mark the place for subsequent processing.

[0033] It is worth noting that: since the insertion rod 12 is elastically connected to the sleeve tube 53 through the spring A4, when sliding over an uneven pipe, the roller 11 slides along the sleeve tube 53 through the insertion rod 12 and compresses the spring A4, so that it can stably slide over the pipe, thereby improving the stability of the equipment during movement.

[0034] In the embodiments of the present invention, please refer to Figure 1 、 Figure 2 、 Figure 6 and Figure 7 , and the adjustment assembly 7 includes a fixed plate 71, the fixed plate 71 is fixedly mounted on the bottom of the semicircular plate 1, and the sliding grooves on both sides of the fixed plate 71 are inserted with sliding side slides 72, and the upper plate head of each side slide 72 is installed with a bending piece 73, and the bending piece 73 includes an elastic semicircular curved rod 731, one end of the elastic semicircular curved rod 731 is rotatably connected to the upper plate head of the side slide 72, and the other end of the elastic semicircular curved rod 731 is hinged to the outer plate wall of the fixed block 31, and the elastic semicircular curved rod 73 1 is provided with a rotatably connected rotating bracket 732 in the middle part, and the rotating bracket 732 is fixedly mounted on the outer ring wall of the semicircular arc plate 1. The lower plate heads of the two side slides 72 extend out of the sliding grooves provided in the fixed plate 71 and are fixedly provided with a middle connecting plate 74. A pull rod 75 is fixedly installed on the lower surface of the middle connecting plate 74. A collar 76 is fixedly installed on the bottom of the pull rod 75, and the collar 76 is sleeved on the sleeve 51 and slidably connected to the sleeve 51. A threaded through hole is provided on the collar 76, and a threaded fixing screw B77 is inserted into the threaded through hole.

[0035] It should be noted that: when the roller 11 in the semicircular arc plate 1 needs to be fitted to the pipe body of the lower half of the pipe, the side slide plate 72 is driven by the upper push-pull rod 75 to drive the connecting end of the elastic semicircular curved rod 731 to slide up. At this time, the hinged end of the elastic semicircular curved rod 731 and the fixed block 31 rotates outward around the rotating bracket 732 and makes the elastic corrugated steel plate 3 open, so it is convenient to fit the semicircular arc plate 1 to the pipe body of the lower half of the pipe. When the fitting is completed, it is lowered along the sleeve 51. Slide the ring 76, and the side slide plate 72 drives the connecting end of the elastic semicircular curved rod 731 to slide down. At this time, the hinged end of the elastic semicircular curved rod 731 and the fixed block 31 rotate inward around the rotating bracket 732 and close the elastic corrugated steel plate 3, so that the smoke sensor B2' on the fixed block 31 can fit the pipe body above the pipe and perform smoke detection. Subsequently, tighten the fixing screw B77 to fix the ring 76 to lock the position of the elastic semicircular curved rod 731.

[0036] In the embodiments of the present invention, please refer to Figure 1 、 Figure 4 and Figure 5 The semi-circular plate 1 is also equipped with a marking component 6 for marking the smoke leakage area of the pipeline, and the smoke sensor A2 and the marking component 6 are respectively arranged on both sides of the roller 11, and the marking component 6 includes a mounting box body 61, which is fixedly mounted on the outer wall of the semi-circular plate 1 and is communicated with the through hole 1a opened in the semi-circular plate 1, and an elastically arranged arc mark 62 is installed in the mounting box body 61. Specifically, a plurality of evenly distributed springs B63 are fixedly mounted on the inner bottom wall of the mounting box body 61, and the other ends of the plurality of springs B63 are fixedly connected to the bottom of the arc mark 62, and a guide rod 64 is fixedly mounted on the bottom of the arc mark 62, and the guide rod 64 passes through the through hole opened at the bottom of the mounting box body 61 and is fixedly connected to a pull rope 65, and the other end of the pull rope 65 is fixedly mounted with a hand pull rod 66.

[0037] It should be noted that: when the smoke sensor A2 and the smoke sensor B2' give an early warning, the hand pull rod 66 is pulled down, and the pull rope 65 drives the guide rod 64 to make the arc mark 62 slide down along the installation box body 61, so that the arc mark 62 compresses the spring B63, and then the hand pull rod 66 is released. Therefore, under the elastic force of the spring B63, the arc mark 62 slides up along the installation box body 61, so that the seal on the arc mark 62 can be imprinted on the pipe at that location, making it convenient for subsequent staff to process the pipe at that location.

[0038] The working principle of the smoke detection equipment provided by this utility model is as follows:

[0039] When performing smoke leak detection on a pipeline, the staff adjusts the length of the telescopic rod 5 according to the installation height of the pipeline. Specifically, the staff slides the sliding rod 52 along the outside of the sleeve 51 to adjust the length of the sleeve 51 and the sliding rod 52. After the adjustment is completed, the fixing screw A54 is tightened to fix the sliding rod 52 on the sleeve 51.

[0040] Then, the adjusting component 7 is used to pull the elastic corrugated steel plate 3 outward to deflect it outward, and the roller 11 in the semicircular arc plate 1 is fitted with the tube body of the lower half of the pipe. Therefore, the smoke sensor A2 in the semicircular arc plate 1 can detect the tube body below the pipe, and then the adjusting component 7 is used to drive the elastic corrugated steel plate 3 to bend toward the inner circle of the pipe, so that the smoke sensor B2' on the fixed block 31 can fit the tube body above the pipe and perform smoke detection. Specifically, when the roller 11 in the semicircular arc plate 1 needs to fit the tube body of the lower half of the pipe, the upper push-pull rod 75 is used to drive the side slide plate 72 to drive the connecting end of the elastic semicircular curved rod 731 to slide up. At this time, the elastic semicircular curved rod 731 and the fixed block are connected. The hinged end of the block 31 rotates outward around the rotating bracket 732 and causes the elastic corrugated steel plate 3 to open, thereby making it convenient to fit the semicircular arc plate 1 to the pipe body of the lower half of the pipe. When the fitting is completed, the collar 76 slides down along the sleeve 51. At this time, the side slide plate 72 drives the connecting end of the elastic semicircular curved rod 731 to slide down. At this time, the elastic semicircular curved rod 731 and the hinged end of the fixed block 31 rotate inward around the rotating bracket 732 and cause the elastic corrugated steel plate 3 to close. Therefore, the smoke sensor B2' on the fixed block 31 can fit the pipe body above the pipe and perform smoke detection. Subsequently, the fixing screw B77 is tightened to fix the collar 76, and the position of the elastic semicircular curved rod 731 can be locked.

[0041] The staff holds the sleeve 51 and pushes the semicircular plate 1 to make the roller 11 slide along the pipe. Therefore, the smoke sensor A2 and the smoke sensor B2' can detect smoke leaks in the pipe. When a smoke leak is detected in a certain pipe, the smoke sensor A2 and the smoke sensor B2' will issue an early warning, and then mark the place through the marking component 6. Specifically, when the smoke sensor A2 and the smoke sensor B2' issue an early warning, the hand pull rod 66 is pulled down, and the pull rope 65 drives the guide rod 64 to make the arc mark 62 slide down along the installation box body 61, so that the arc mark 62 compresses the spring B63, and then the hand pull rod 66 is released. Therefore, under the elastic force of the spring B63, the arc mark 62 slides up along the installation box body 61, so that the seal on the arc mark 62 can be imprinted on the pipe at that location, which is convenient for subsequent staff to process the pipe at that location.
