The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation on the present application.

[0040] At present, the detection angle of the spark detector is not adjustable, so that the installation precision of the spark detector is required to be high.

[0041] In view of the above problems, in an embodiment of the present application, a spark detection device is provided, such as Figure 1As shown, the spark detection device comprises a housing 100, a first support 200, a second support 300, a first driving device 500, a second driving device 600 and a controller 700, wherein the first support 200 and the second support 300 are both arranged in the housing 100, the second support 300 is rotationally connected with the first support 200, the output end of the first driving device 500 is connected with the first support 200 and drives the first support 200 to rotate around the X axis, the output end of the second driving device 600 is connected with the second support 300 and drives the second support 300 to rotate around the Y axis, the second support 300 is provided with a detector 400 for detecting sparks, and the first driving device 500, the second driving device 600 and the detector 400 are all in data connection with the controller 700, so that automatic control can be realized through the controller 700, saving manpower.

[0042] By arranging the detector 400 on the second support 300 and rotationally connecting the second support 300 with the first support 200, when the first driving device 500 drives the first support 200 to rotate around the X axis, the second support 300 connected with the first support 200 can be driven to rotate around the X axis, and then the detector 400 arranged on the second support 300 can be driven to rotate around the X axis, and when the second driving device 600 drives the second support 300 to rotate around the Y axis, the detector 400 can be driven to rotate around the Y axis, so as to finally realize the adjustment of the angle of the detector 400, reduce the installation precision requirement of the above-mentioned spark detection device, and then reduce the difficulty of installation by workers. By controlling the first driving device 500 and the second driving device 600 through the controller 700, intelligent control of the angle of the detector 400 can be realized, and then automatic scanning detection of whether there is a spark in a certain space can be realized. Compared with the traditional spark detection device which can only detect sparks passing through the cross section of the pipeline, the above-mentioned spark detection device has a larger detection range and stronger applicability.

[0043] Further, continuing to refer to Figure 1 , the housing 100 can comprise a bottom plate 110, a frame 120 and a protective cover 130, the bottom plate 110 is sealingly connected with the protective cover 130 through the frame 120, and the first support 200, the first driving device 500, the second driving device 600 and the controller 700 can all be fixed on the bottom plate 110. By connecting the protective cover 130 with the bottom plate 110 through the frame 120, the connection strength between the protective cover 130 and the bottom plate 110 can be improved, so as to avoid the loosening of the protective cover 130 and reduce the dustproof effect of the protective cover 130.

[0044] Preferably, a sealing element can be arranged between the bottom plate 110 and the protective cover 130 to improve the sealing performance between the bottom plate 110 and the protective cover 130. In an embodiment, the sealing element can be a sealing ring made of flexible material.

[0045] Preferably, considering that the detector 400 needs to detect the spark, therefore, the protective cover 130 should be made of transparent material, for example, can be glass or plastic and the like.

[0046] Preferably, in an embodiment, the first driving device 500, the second driving device 600 and the controller 700 can be connected with the bottom plate 110 through bolt connection, the bolt connection has good performance and is convenient to disassemble, facilitating maintenance and replacement.

[0047] Preferably, a mounting seat can be arranged on the bottom plate 110, the first support 200 is rotationally connected with the mounting seat, arranging the mounting seat can improve the connection strength between the first support 200 and the bottom plate 110, and ensure the reliability of rotation of the first support 200. In an embodiment, the mounting seat can be connected with the bottom plate 110 through bolt connection; in other embodiments, the mounting seat can also be integrally formed with the bottom plate 110, and can be arranged according to actual needs.

[0048] Further, as shown in Figure 1 and Figure 2 , the second support 300 can include a fixed plate 310, a connecting piece 320 and a first connecting shaft 330, one end of the connecting piece 320 is connected with the fixed plate 310, and the other end is connected with the first connecting shaft 330, the detector 400 is arranged on the fixed plate 310, which can ensure the reliability of the connection between the detector 400 and the second support 300, and further ensure the reliability of the work of the detector 400, a first connecting hole 210 is arranged on the first support 200, the first connecting shaft 330 is connected with the first connecting hole 210, and the first connecting shaft 330 can rotate in the first connecting hole 210, so that the second support 300 rotates around the Y axis.

[0049] Preferably, in order to improve the mechanical strength of the second support 300 and the reliability of the connection between the second support 300 and the first support 200, two connecting pieces 320 can be arranged, and the two connecting pieces 320 are arranged on the two sides of the fixed plate 310, and the two connecting pieces 320 are connected with the two ends of the first connecting shaft 330, specifically, during assembly, the first connecting shaft 330 is first arranged in the first connecting hole 210, and then the connecting piece 320 is connected with the first connecting shaft 330, in order to ensure that the second support 300 can rotate with the rotation of the first connecting shaft 330, the connecting piece 320 needs to be fixedly connected with the first connecting shaft 330. In an embodiment, the first connecting shaft 330 and the connecting piece 320 can be connected by a bolt connection mode, in order to improve the reliability of the connection between the connecting piece 320 and the first connecting shaft 330, a plurality of bolts can be arranged, and in this embodiment, three bolts are arranged, and the three bolts are arranged in a triangular structure. In other embodiments, other modes can also be adopted, as long as the connection mode can ensure the fixed connection between the connecting piece 320 and the first connecting shaft 330, which is within the protection scope of the present application.

[0050] Preferably, in an embodiment, a gasket can be arranged between the connecting piece 320 and the first support 200, so as to avoid the abrasion of the first support 200 due to the rotation of the second support 300, while ensuring the smooth rotation of the second support 300. In another embodiment, the first connecting shaft 330 can be a shaft with a shaft shoulder, a first shaft sleeve is arranged between the connecting piece 320 and the first support 200, so as to avoid the abrasion of the second support 300 and ensure the smooth rotation of the second support 300.

[0051] Further, continuing to refer to Figure 1 The worm gear 340 and the worm 350 can be arranged, the second driving device 600 is connected with the second support 300 through the worm gear 340 and the worm 350, specifically, the worm gear 340 and the worm 350 are engaged, the output end of the second driving device 600 is connected with the worm 350 and can drive the worm 350 to rotate, the worm 350 is arranged along the X-axis direction, the middle of the worm gear 340 is provided with a second connecting hole (not shown in the figure), the first connecting shaft 330 is arranged in the second connecting hole and is fixedly connected with the second connecting hole, when the second driving device 600 drives the worm 350 to rotate, the worm gear 340 rotates with the worm 350, the worm gear 340 drives the first connecting shaft 330 fixedly connected therewith to rotate, the first connecting shaft 330 drives the second support 300 fixedly connected therewith to rotate, thereby realizing the rotation of the detector 400 around the Y-axis.

[0052] Preferably, continuing to refer to Figure 2In one embodiment, a first connecting key 331 can be arranged on the first connecting shaft 330, and a key groove matching the first connecting key 331 can be arranged on the inner wall of the second connecting hole. The fixed connection between the first connecting shaft 330 and the second connecting hole is achieved through the key connection, which avoids the rotation of the first connecting shaft 330 relative to the second connecting hole, and further improves the reliability of the rotation of the detector 400 around the Y axis.

[0053] Optionally, the first connecting key 331 can be a flat key or a semicircular key, which can be selected according to actual needs.

[0054] Preferably, an installation groove can be arranged on the first support 200, and the worm wheel 340 is accommodated in the installation groove, and the worm 350 is installed on the mounting seat. This can optimize the structure of the first support 200, reduce the occupied space of the first support 200 and the second support 300, and further reduce the overall size of the above-mentioned spark detection device, and improve the universality of the above-mentioned spark detection device.

[0055] Further, referring to Figure 1 The first limit switch 220 can be arranged on the first support 200, and the first limit switch 220 is in data connection with the second driving device 600. The first limit switch 220 is used to control the opening and closing of the second driving device 600. When the first limit switch 220 senses the connecting piece 320, the second driving device 600 is controlled to stop driving, which avoids the rotation angle of the second support 300 being too large, causing the detector 400 to collide with the first driving device 500 or the second driving device 600 or the bottom plate 110 and be damaged, and improves the service life and working reliability of the detector 400. In one embodiment, the first limit switch 220 can be a photoelectric switch; in other embodiments, the first limit switch 220 can also be a proximity switch, which can be selected according to actual needs.

[0056] Preferably, considering that the second support 300 can be close to the positive half axis of the X axis and the negative half axis of the X axis, the first limit switch 220 needs to be arranged at least twice, and the two first limit switches 220 need to be arranged on both sides of the connecting piece 320. Since the closer the horizontal distance between the first limit switch 220 and the connecting piece 320, the smaller the rotation angle of the second support 300, the position of the first limit switch 220 can be arranged according to actual needs, as long as the detector 400 is not collided. In this embodiment, the rotation angle range of the second support 300 is 30°-150°.

[0057] Further, referring to Figure 1The first limiting piece 230 can be arranged on the first support 200, the connecting piece 320 can abut against the first limiting piece 230, the first connecting hole 210 is a waist-shaped hole, the first connecting shaft 330 can move in the first connecting hole 210, the first spring 360 is arranged, one end of the first spring 360 is connected with the connecting piece 320, and the other end is connected with the first support 200, when the connecting piece 320 abuts against the first limiting piece 230, the connecting piece 320 continues to rotate due to inertia, the first connecting shaft 330 moves in the waist-shaped hole, and the worm wheel 340 and the worm 350 are separated under the action of inertia, at this time, the second support 300 stops rotating, the first spring 360 exerts a pulling force on the connecting piece 320 under the action of the elastic force, and the worm wheel 340 and the worm 350 are restored to engagement. By arranging the waist-shaped hole and the first spring 360, the detector 400 can be prevented from colliding with the bottom plate 110 or the first driving device 500 or the second driving device 600 due to the mistake of the worker when the second driving device 600 is manually controlled, and the reliability of the detector 400 is ensured. The worm wheel 340 and the worm 350 can be engaged under the action of the first spring 360, the equipment can continue to be used due to the mistake of the worker, and the reliability of the above-mentioned spark detection device is improved.

[0058] Preferably, considering that the second support 300 can be close to the positive half axis of the X axis and the negative half axis of the X axis, the first limiting piece 230 needs to be arranged at least twice, and the two first limiting pieces 230 need to be arranged on the two sides of the connecting piece 320. Since the horizontal distance between the first limiting piece 230 and the connecting piece 320 is closer, the angle through which the second support 300 can rotate is smaller, so the position of the first limiting piece 230 can be arranged according to actual needs, as long as the detector 400 can be prevented from being collided. In the embodiment, the first limiting switch 220 and the first limiting piece 230 are arranged at the same time.

[0059] As a preferred technical solution, since the connecting piece 320 can be arranged twice, the first spring 360 can also be arranged twice, the working reliability of the worm wheel 340 and the worm 350 can be improved, the worm wheel 340 cannot be reset due to spring failure, the second support 300 cannot rotate around the Y axis, and the angle adjustment of the detector 400 is affected.

[0060] Further, continuing to refer to Figure 1A second limit switch 150 can be installed on the base plate 110. The second limit switch 150 is connected to the controller 700 via data connection. When the first bracket 200 approaches the second limit switch 150, the controller 700 receives data and controls the first drive device 500 to stop driving the first bracket 200 to rotate around the X-axis. Considering that the first bracket 200 can approach both the positive and negative half-axis of the Y-axis, the second limit switch 150 can be installed on both sides of the first bracket 200 to prevent the first bracket 200 from colliding with the base plate 110 due to excessive rotation angle, thereby damaging the detector 400. Since the closer the second limit switch 150 is to the first bracket 200, the smaller the rotation angle range of the first bracket 200, the position of the second limit switch 150 can be set according to actual needs. In this embodiment, the rotation angle of the first bracket is 30° to 150°.

[0061] To facilitate understanding, the angle adjustment process of the above-mentioned spark detection device is described below:

[0062] like Figure 1 As shown, the first driving device 500 can drive the detector 400 to adjust its angle within a range of 30° to 150° in a plane with the X-axis as the rotation axis. Specifically, the first driving device 500 can drive the first bracket 200 to rotate around the X-axis by 30° to 150°, thereby driving the second bracket 300 connected to the first bracket 200 to rotate around the X-axis by 30° to 150°, thus enabling the detector 400 mounted on the second bracket 300 to rotate around the X-axis by 30° to 150°.

[0063] The second driving device 600 drives the detector 400 to adjust the angle in the range of 30°-150° in the plane with the Y axis as the rotation axis. Specifically, the second driving device 600 drives the worm 350 and the worm wheel 340 to rotate, the worm wheel 340 drives the second support 300 to rotate, and the angle adjustment of the detector 400 is realized. When the second driving device 600 adjusts the detector 400 to 30° or 150°, the first limit switch 220 sends an alarm signal to indicate that the angle has been adjusted to the limit. When the adjustment personnel continue to adjust out of range, the connecting piece 320 abuts against the first limiting piece 230 and continues to rotate, driving the first spring 360 to stretch further. At this time, the first connecting shaft 330 moves in the first connecting hole 210, and at the same time, a certain tension is applied to the worm wheel 340, so that the worm wheel 340 is lifted, and then the worm wheel 340 and the worm 350 are separated. Then, under the action of the retraction force of the first spring 360, the first connecting shaft 330 moves in the first connecting hole 210, and the first connecting shaft 330 applies a certain pressure to the worm wheel 340, so that the worm wheel 340 and the worm 350 restore the meshing state. In the case that the second driving device 600 does not stop rotating, the output is cut off to prevent the detector 400 from colliding with the first driving device 500 or the second driving device 600 or the bottom plate 110 and being damaged.

[0064] Further, as shown in Figure 1 and Figure 3 A cleaning device 800 can be provided, and the cleaning device 800 is arranged on the third support 900. The third support 900 is rotationally connected with the shell 100. Specifically, a second connecting shaft 140 can be arranged on the shell 100, so that the shell 100 is rotationally connected with the third support 900 through the second connecting shaft 140. In the embodiment, the second connecting shaft 140 is arranged on the frame 120, and the second connecting shaft 140 is arranged opposite along the X axis. The cleaning device 800 includes a cleaning part 810 and a bidirectional output driving device 820. The cleaning part 810 can be attached to the outer surface of the shell 100, and is used for removing dust accumulated on the outer surface of the shell 100. Specifically, the cleaning part 810 is rotationally connected with the third support 900, and the bidirectional output driving device 820 is connected with the shell 100 at one end and connected with the cleaning part 810 at the other end. On the one hand, the shell 100 can rotate around the X axis, so that the outer surface of the shell 100 is attached to the cleaning part 810. On the other hand, the cleaning part 810 rotates around the Z axis to clean the dust on the outer surface of the shell 100.

[0065] Preferably, continuing to refer to Figure 3In one embodiment, the outer surface of the shell 100 is semispherical, and the cleaning part 810 is a hollow semispherical shape, facilitating cleaning of the outer surface of the shell 100. The cleaning part 810 is provided with a cleaning cloth or a cleaning brush at the joint with the outer surface of the shell 100, facilitating removal of dust and impurities, ensuring cleanliness and good light transmittance of the outer surface of the shell 100, avoiding inaccurate or even undetectable spark detection by the detector 400 due to dust and impurities accumulation, and improving the accuracy of detection results.

[0066] Preferably, as shown in one embodiment, the bidirectional output driving device 820 can be a double-shaft motor, one end of the double-shaft motor is provided with a conical gear 821, and a semicircular conical gear 910 matching the conical gear 821 is arranged on the second connecting shaft 140. Rotation of the double-shaft motor can drive the semicircular conical gear 910 to rotate, and when the semicircular conical gear 910 rotates 180°, the shell 100 rotates 180°, at which time the outer surface of the shell 100 is in contact with the cleaning part 810. The semicircular conical gear 910 no longer rotates with the double-shaft motor, and the shell 100 is stationary, ensuring the reliability of the cleaning work of the cleaning device 800. Figure 4 Preferably, as shown in one embodiment, the semicircular conical gear 910 includes a movable conical gear 911, a fixed part 912, and a second limiting part. A third limiting part 920 is arranged on the third support 900. The movable conical gear 911 is connected to the adjacent immovable conical gear through a second spring 913. When the second limiting part abuts against the third limiting part 920, the semicircular conical gear 910 cannot continue to rotate. At this time, the double-shaft motor still works normally, and the conical gear 821 will exert pressure on the semicircular conical gear 910. By arranging the movable conical gear 911, the pressure of the conical gear 821 can be buffered. The movable conical gear 911 further compresses the second spring 913 with the rotation of the conical gear 821. When the movable conical gear 911 is separated from the conical gear 821, the second spring 913 reversely pushes the movable conical gear 911 to restore the initial position. In this way, the conical gear 821 continues to rotate, while the semicircular conical gear 910 does not rotate with the conical gear 821, avoiding affecting the normal work of the double-shaft motor. The fixed part 912 can abut against the movable conical gear 911 to limit the movement range of the movable conical gear 911, ensuring that the movable conical gear 911 can correctly engage with the conical gear 821, and ensuring the reliability of the rotation of the shell 100.

[0067] Figure 5 Preferably, as shown in one embodiment, the semicircular conical gear 910 includes a movable conical gear 911, a fixed part 912, and a second limiting part. A third limiting part 920 is arranged on the third support 900. The movable conical gear 911 is connected to the adjacent immovable conical gear through a second spring 913. When the second limiting part abuts against the third limiting part 920, the semicircular conical gear 910 cannot continue to rotate. At this time, the double-shaft motor still works normally, and the conical gear 821 will exert pressure on the semicircular conical gear 910. By arranging the movable conical gear 911, the pressure of the conical gear 821 can be buffered. The movable conical gear 911 further compresses the second spring 913 with the rotation of the conical gear 821. When the movable conical gear 911 is separated from the conical gear 821, the second spring 913 reversely pushes the movable conical gear 911 to restore the initial position. In this way, the conical gear 821 continues to rotate, while the semicircular conical gear 910 does not rotate with the conical gear 821, avoiding affecting the normal work of the double-shaft motor. The fixed part 912 can abut against the movable conical gear 911 to limit the movement range of the movable conical gear 911, ensuring that the movable conical gear 911 can correctly engage with the conical gear 821, and ensuring the reliability of the rotation of the shell 100.

[0068] ​As a preferred technical scheme, one end of the fixing member 912 can be fixedly connected with the body of the semi-circular bevel gear 910, and the other end is arranged in the movable bevel gear 911. In order to better limit the movement range of the movable bevel gear 911 and ensure the reliability of the semi-circular bevel gear 910, the other end of the fixing member 912 is arranged in a circular arc connecting column structure, and the arc is the same as the arc of the body of the semi-circular bevel gear 910, so that the bottom of the movable bevel gear 911 is always attached to the body of the semi-circular bevel gear 910 and moves along the outer edge of the body of the semi-circular bevel gear 910. In order to better fix the second spring 913, a part of the second spring 913 is sleeved on the fixing member 912 and is accommodated in the movable bevel gear 911. Specifically, a containing groove is arranged at the position where the fixing member 912 is arranged in the movable bevel gear 911, and the second spring 913 is accommodated in the containing groove.

[0069] Further, the other end of the double-shaft motor is provided with a small cylindrical gear 930, and a large cylindrical gear 940 is connected to the cleaning part 810. The small cylindrical gear 930 is connected with the large cylindrical gear 940, and when the double-shaft motor rotates, the small cylindrical gear 930 drives the large cylindrical gear 940 to rotate, thereby realizing the rotation of the cleaning part 810 around the Z axis.

[0070] Preferably, as shown in Figure 6 The speed change gear 950 can be arranged between the small cylindrical gear 930 and the large cylindrical gear 940, and the rotation speed of the cleaning part 810 can be controlled by using different sizes of the speed change gear 950.

[0071] Preferably, the second shaft sleeve 960 can be arranged between the large cylindrical gear 940 and the cleaning part 810. On the one hand, the second shaft sleeve 960 can improve the connection strength between the large cylindrical gear 940 and the cleaning part 810, and ensure the reliability of the cleaning work of the cleaning part 810; on the other hand, the second shaft sleeve 960 can facilitate the disassembly between the large cylindrical gear 940 and the cleaning part 810. It is conceivable that the second shaft sleeve 960 can also be arranged between the small cylindrical gear 930 and the double-shaft motor, and can be arranged according to actual needs.

[0072] In order to facilitate understanding, the self-cleaning process of the above-mentioned spark detection device will be introduced:

[0073] As shown in Figure 3As shown, when the manual control or the automatic cleaning cycle is reached, the dual-shaft motor is started, the shell 100 is rotated by 180° through the semi-circular bevel gear 910, when the second limiting piece on the semi-circular bevel gear 910 contacts the third limiting piece 920 on the third support 900, the conical gear 821 continues to rotate with the rotation of the dual-shaft motor, the movable conical tooth 911 of the semi-circular bevel gear 910 is further compressed with the rotation of the conical gear 821, when the movable conical tooth 911 is separated from the conical gear 821, the second spring 913 reversely pushes the movable conical tooth 911 to restore the initial position, and thus reciprocates, which separates the rotation of the dual-shaft motor from the rotation of the shell 100 under the condition that the dual-shaft motor does not stop, so that the above-mentioned spark detection device is kept in the self-cleaning state; at the same time, the other end of the dual-shaft motor drives the cleaning part 810 to rotate continuously through the small cylindrical gear 930, the speed-changing gear 950 and the large cylindrical gear 940, which cleans the outer surface of the shell 100, ensures the cleanliness and good light transmittance of the outer surface of the shell 100, avoids the dust and impurities accumulated on the outer surface of the shell 100 from causing the detector 400 to detect inaccurately or even not to detect the spark, improves the accuracy of the detection result, and effectively prevents the fire, explosion and other accidents caused by the false report. After cleaning, the dual-shaft motor reversely rotates to drive the shell 100 to restore to the working position before cleaning.

[0074] In addition, since the first driving device 500, the second driving device 600 and the bidirectional output driving device 820 are connected with the controller 700, the automatic cleaning database is stored in the controller 700, the automatic cleaning database has different recommended cleaning periods of different dust concentrations and types, the user can select the required cleaning period or set the automatic cleaning period according to the actual situation, and at the same time, the cleaning can also be performed in a manual mode.

[0075] Further, the self-checking test lamp 1000 can be arranged in the shell 100 and connected with the controller 700 in data, the self-checking test lamp 1000 is lighted by manual or setting the automatic self-checking period, the infrared or ultraviolet light is used to simulate the spark, and it is detected whether the detector 400 can normally work, if the detector 400 has no output signal, it indicates that the detector 400 has a fault, at this time, the controller 700 sends the detector 400 fault alarm information to alarm.

[0076] Preferably, the self-checking test lamp 1000 can be arranged on the second support 300, since the detector 400 is arranged on the second support 300, the self-checking test lamp 1000 is arranged on the second support 300 close to the detector 400, which can avoid the light shielding caused by other reasons and thus mistakenly think that the detector 400 has a fault, and improves the reliability of the self-detection of the above-mentioned spark detection device.

[0077] The first driving device 500 is arranged to drive the first support 200 to rotate around the X axis, and the second driving device 600 is arranged to drive the second support 300 to rotate around the Y axis, so that the angle of the detector 400 can be adjusted in a two-dimensional plane (in the range of the X axis as the rotation axis and the Y axis as the rotation axis), the requirement for the installation mode and precision can be reduced through the angle adjustment of the detector 400, and the automatic scanning detection of whether there is a spark in a certain space can be realized, compared with the traditional spark detection device which can only detect the spark passing through the pipe cross section, the above spark detection device has a larger detection range and stronger applicability, and the installation, use and maintenance costs can be further reduced.

[0078] The cleaning device 800 is arranged to realize the automatic periodic / manual cleaning function, the automatic cleaning database is stored in the controller 700, the automatic cleaning database is provided with recommended cleaning periods of different dust concentrations and types, the user can select the required cleaning period or set the automatic cleaning period according to the actual situation, and the cleaning can also be performed in a manual mode, so that the cleanliness and good light transmittance of the outer surface of the shell 100 are ensured, the reliability of the spark detection system is improved, and the accidents such as fire and explosion caused by false reporting are effectively prevented.

[0079] The self-checking test lamp 1000 is arranged, and the infrared or ultraviolet light is used to simulate the spark, so that whether the spark detection device is in a normal state is automatically periodically / manually checked, the spark detection device with a fault can be found in time and repaired or replaced, the pertinence and effectiveness of the maintenance are greatly improved, and the stability and reliability of the spark detection are ensured.
