Description

Technical Field

[0001] This disclosure relates to the field of boiler flame detection technology, and more specifically, to a clearing tool. Background Technology

[0002] Flame detection devices are used to detect the combustion conditions of boilers. The end of the flame detection device that extends into the boiler is equipped with a flame detection probe. Due to the long-term combustion environment inside the boiler, coking easily occurs on the flame detection probe, which can clog the optical flame sensor and affect the detection accuracy of the optical flame sensor. In order to ensure the normal operation of the flame detection device, the flame detection probe needs to be cleaned and maintained regularly. However, the flame detection sleeve of the flame detection device is long and dark, and has an "S" bend arrangement inside. There are no suitable maintenance tools for cleaning, which makes the cleaning operation difficult and inefficient. Utility Model Content

[0003] The purpose of this disclosure is to provide a declogging tool for cleaning coke deposits on the flame detector probe of a flame detection device, thereby improving declogging efficiency.

[0004] To achieve the above objectives, this disclosure provides a clearing tool for use in a flame detection device for boilers, comprising a sleeve and a drilling assembly;

[0005] The drilling assembly includes a drill bit, a drive unit, and a rotating rod. The sleeve is used to extend into the flame detection sleeve of the flame detection device. The drill bit and the drive unit are located at the two ends of the rotating rod, respectively. The drive unit is used to drive the rotating rod to rotate, thereby driving the drill bit to rotate.

[0006] The sleeve is a rigid flexible tube, and the rotating rod is a rigid flexible rod.

[0007] Optionally, the unblocking tool further includes an endoscope, the probe of which is located at one end of the casing near the drill bit, and the endoscope is used to capture image information inside the fire detection casing.

[0008] Optionally, the end of the endoscope away from the probe is connected to a control module and a display screen. The control module is used to control the opening and closing of the endoscope, and the display screen is used to display images captured by the endoscope.

[0009] Optionally, the endoscope is detachably connected to the cannula.

[0010] Optionally, the endoscope is provided with a cylindrical interface, through which the endoscope is connected to the cannula.

[0011] Optionally, the driving component includes a mounting part and a driving part. The mounting part is detachably mounted on one end of the sleeve located outside the flame detector sleeve, and the driving part is used to drive the rotating rod to rotate.

[0012] Optionally, the drill bit is detachably connected to the rotating rod.

[0013] Optionally, the drill bit includes a connecting section, the side wall of which has a first pin hole, and the rotating rod has a second pin hole. The connecting section is sleeved on the rotating rod, and the first pin hole and the second pin hole are used for connecting and fixing the rod.

[0014] Optionally, the drill bit is a flower-shaped drill bit.

[0015] Optionally, the sleeve is a corrugated pipe.

[0016] With the above technical solution, the drill bit and drive unit are respectively located at both ends of the rotating rod, and the sleeve is fitted over the outside of the rotating rod. The sleeve is inserted into the flame detector sleeve until the drill bit reaches the coking area of ​​the flame detector probe. The drive unit then drives the rotating rod to rotate, which in turn drives the drill bit to rotate. The rotating drill bit cleans the coking at the flame detector probe in the flame detector sleeve, thus ensuring the normal operation of the flame detector probe. Furthermore, operators can use a de-clogging tool to clean the coking in the flame detector sleeve, effectively improving cleaning efficiency and reducing cleaning difficulty. Additionally, by fitting the sleeve over the outside of the rotating rod, the rotation of the rod avoids affecting the inside of the flame detector sleeve, and it also facilitates the operator holding the sleeve to insert both the sleeve and the rotating rod into the flame detector sleeve. The sleeve is designed as a rigid flexible tube, and the rotating rod is designed as a rigid flexible rod. On the one hand, the rigid material of the sleeve and the rotating rod makes it easy for the operator to apply force to insert the sleeve and the rotating rod into the coking area of ​​the fire detector probe; on the other hand, the flexible tube and the flexible rod make it easy for the sleeve and the rotating rod to pass through the bends inside the fire detector probe and avoid being obstructed at the bends.

[0017] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this disclosure can be understood according to the specific circumstances.

[0027] Please see Figure 1 and Figure 2This disclosure provides a clearing tool 100 for use in a flame detection device of a boiler, including a sleeve 1 and a drilling assembly 2; the drilling assembly 2 may include a drill bit 21, a drive member 22 and a rotating rod 23, the sleeve 1 is used to extend into the flame detection sleeve of the flame detection device, the drill bit 21 and the drive member 22 are respectively located at both ends of the rotating rod 23, the drive member 22 is used to drive the rotating rod 23 to rotate, so as to drive the drill bit 21 to rotate;

[0028] Among them, sleeve 1 is a rigid flexible tube, and rotating rod 23 is a rigid flexible rod.

[0029] With the above technical solution, the drill bit 21 and the drive unit 22 are respectively located at both ends of the rotating rod 23. The sleeve 1 is fitted onto the outside of the rotating rod 23. The sleeve 1 is inserted into the flame detector sleeve until the drill bit 21 reaches the coking area of ​​the flame detector probe. The drive unit 22 drives the rotating rod 23 to rotate, which in turn drives the drill bit 21 to rotate. The rotating drill bit 21 cleans the coking at the flame detector probe in the flame detector sleeve, thereby ensuring the normal operation of the flame detector probe. Moreover, the operator can use a de-clogging tool to clean the coking in the flame detector sleeve, which effectively improves the cleaning efficiency and reduces the cleaning difficulty. In addition, by fitting the sleeve 1 onto the outside of the rotating rod 23, the rotation of the rotating rod 23 is prevented from affecting the inside of the flame detector sleeve. At the same time, it is convenient for the operator to hold the sleeve 1 to insert the sleeve 1 and the rotating rod 23 into the flame detector sleeve. The sleeve 1 is a rigid flexible tube, and the rotating rod 23 is a rigid flexible rod. On the one hand, the sleeve 1 and the rotating rod 23 are made of rigid materials, which makes it easy for the operator to apply force to insert the sleeve 1 and the rotating rod 23 into the coking area of ​​the fire detector probe. On the other hand, the sleeve 1 is a flexible tube, and the rotating rod 23 is a flexible rod, which makes it easy for the sleeve 1 and the rotating rod 23 to pass through the bends inside the fire detector probe and avoid being obstructed at the bends.

[0030] Please see Figure 1 and Figure 2 In one embodiment of this disclosure, the unblocking tool 100 may further include an endoscope 3. The probe 31 of the endoscope 3 is disposed at the end of the sleeve 1 near the drill bit 21. The endoscope 3 is used to capture image information inside the flame detector sleeve. In this way, it is easier for the operator to determine the specific location of the coking point, thereby facilitating the determination of the direction of travel and arrival position of the drill bit 21. At the same time, it is beneficial to judge the operation status and damage of the internal components and circuits of the flame detector sleeve.

[0031] Optionally, the endoscope 3 may be equipped with an illumination device to illuminate the inside of the flame detection sleeve, so that the probe 31 of the endoscope 3 can capture image information inside the flame detection sleeve.

[0032] Please see Figure 1 and Figure 2The end of the endoscope 3 furthest from the probe 31 can be connected to a control module 4 and a display screen 5. The control module 4 is used to control the opening and closing of the endoscope 3, and the display screen 5 is used to display the images captured by the endoscope 3. In this way, it is convenient for the operator to observe the internal condition of the flame detector sleeve and the position of the drill bit 21, so as to more accurately remove the char from the flame detector probe in the flame detector sleeve.

[0033] It should be noted that the endoscope 3 can be connected to the control module 4 and the display screen 5 via a wired connection or via a wireless signal; this disclosure does not limit the connection.

[0034] Please see Figure 1 and Figure 2 Optionally, the endoscope 3 and the cannula 1 can be detachably connected to facilitate the replacement and maintenance of the endoscope 3.

[0035] In one embodiment of this disclosure, the endoscope 3 may be provided with a cylindrical interface 32, through which the endoscope 3 is connected to the cannula 1. This arrangement, by connecting the endoscope 3 and the cannula 1 through the cylindrical interface 32, facilitates the integration of the endoscope 3 and the cannula 1 into one unit, thereby enabling the endoscope 3 to move via the cannula 1.

[0036] It is conceivable that the cylindrical interface 32 can be equipped with a magnetic cylindrical interface 32, and the endoscope 3 is connected to the sleeve 1 by magnetic attraction, which ensures a stable connection between the endoscope 3 and the sleeve 1 while facilitating disassembly.

[0037] Please see Figure 1 and Figure 2 In one embodiment of this disclosure, the driving component 22 may include a mounting portion 221 and a driving portion 222. The mounting portion 221 is detachably mounted on the end of the sleeve 1 located outside the flame detector sleeve, and the driving portion 222 is used to drive the rotating rod 23 to rotate. The driving component 22 is connected to the sleeve 1 via the mounting portion 221. An operator can operate the driving portion 222 to drive the rotating rod 23 to rotate, thereby causing the drill bit 21 to rotate. In this way, a stable connection between the sleeve 1 and the driving component 22 is ensured, and the sleeve 1 does not affect the rotation of the rotating rod 23.

[0038] Optionally, the drill bit 21 is detachably connected to the rotating rod 23. This facilitates the replacement of the drill bit 21.

[0039] Please see Figure 1 and Figure 2In one embodiment of this disclosure, the drill bit 21 includes a connecting section 211. A first pin hole 212 is formed on the side wall of the connecting section 211, and a second pin hole 231 is formed on the rotating rod 23. The connecting section 211 is sleeved over the rotating rod 23. The first pin hole 212 and the second pin hole 231 are used for connecting and fixing the rod. In this way, the drill bit 21 and the rotating rod 23 are detachably connected through the first pin hole 212 and the second hole, ensuring that the rotation of the rotating rod 23 drives the drill bit 21 to rotate while facilitating the disassembly of the drill bit 21.

[0040] It is conceivable that the drill bit 21 and the rotating rod 23 can also be detachably connected by means of plug-in or bolt connection.

[0041] In this disclosure, the drill bit 21 and the rotating rod 23 are detachably connected, the drive component 22 is detachably installed on the end of the sleeve 1 located outside the flame detection sleeve through the mounting part 221, and the endoscope 3 is detachably connected to the sleeve 1. This arrangement facilitates the disassembly and installation of the unblocking tool 100, and is beneficial for the transportation and storage of the unblocking tool 100 when cleaning multiple flame detection sleeves of the boiler.

[0042] In one embodiment of this disclosure, the drill bit 21 may be a flower-shaped drill bit 21.

[0043] In other embodiments of this disclosure, the drill bit 21 can be configured in any shape suitable for descaling, such as a thread tapping drill bit 21.

[0044] In one embodiment of this disclosure, the sleeve 1 can be a corrugated pipe.

[0045] In other embodiments of this disclosure, the sleeve 1 may be a rubber tube or the like.
