[0002] Since there are many circuits used in building facilities, in order to avoid leakage and other phenomena in some special equipment, such as fire-fighting equipment or elevator equipment, it is generally necessary to regularly inspect the electrical system in this area to avoid serious safety accidents caused by leakage. Leakage is the leakage of current caused by insulation damage or other reasons. When the housing of the appliance and the live wire of the mains are connected for some reason and there is a certain potential difference between them and the ground, leakage will occur.

[0003] The existing leakage detection devices for building facilities generally adopt the method of using leakage detectors to detect different equipment. However, considering the safety of the staff during use, the leakage detection instruments are placed in the environment for a long time to detect the leakage of the equipment.

[0019] The present invention also provides a method for using a building facility leakage detection device, based on the above-mentioned building facility leakage detection device, comprising the following steps:

[0020] S1. Fix the loading box near the detection area with bolts, and put the leakage detector required for detection into the slot of the loading box;

[0021] S2, then the meshing stop assembly releases the restriction on the rotating gear, and the rotating shaft is rotated to drive the rotating gear to rotate, the rotating gear rotates to make the two rotating racks move in the direction of approaching each other, and the rotating rack drives the displacement cross plate to move in the direction of approaching the leakage detector through the bent square rod, at this time the elastic top connection assembly contacts and fixes the leakage detector, and after the fixation is completed, the stop tooth block of the meshing stop assembly is meshed with the rotating gear to limit the rotating gear;

[0022] S3. The operator observes the data transmitted by the leakage detector to detect whether leakage occurs in the area for a long time;

[0023] S4. When it is necessary to clean the dust on the sensing signal end of the leakage detector, first control the two electric telescopic rods to drive the corresponding U-shaped square plate to move back and forth. At this time, the U-shaped square plate drives the meshing rack to move back and forth through the L-shaped square rod, and the meshing rack drives the driving gear and the driving shaft to rotate back and forth. The driving shaft drives the auxiliary shaft and the compound moving disc to rotate through the bevel gear set. At this time, the compound moving cylinder moves back and forth in the compound moving cross block and moves the compound moving cross block through the cooperation of the guide rod assembly. The compound moving cross block drives the cleaning scraper to move back and forth on the top surface of the leakage detector through the extended square rod to clean the dust;

[0024] S5. When the two electric telescopic rods work and drive the corresponding U-shaped square plates to move back and forth, the U-shaped square plates drive the positioning round rods to move back and forth in the corresponding positioning cylinders. The gas in the positioning cylinders is ejected from the high-pressure nozzles through the air delivery pipes and blown to the sensing signal end of the leakage detector to blow away the dust; and the sprayer sprays water mist, and with the cooperation of the water mist, the sensing signal end is deeply cleaned.

[0025] The present invention adopts the above technical solution and has the following beneficial effects:

[0026] 1. In the present invention, the leakage detector is placed in a loading box, and the loading box is fixedly installed near the detection area by bolts, so that the leakage detector can detect whether there is leakage in the circuit at the current position for a long time, avoiding safety problems caused by the operator being too close to the leakage area due to holding or other behaviors, thereby improving the safety of the device when in use.

[0027] 2. In the present invention, the rotating shaft is controlled to rotate, so that the rotating gear can be driven to rotate; the rotation of the rotating gear drives the two rotating racks to move in the direction of approaching each other. At this time, the movement of the two rotating racks drives the displacement cross plate to move in the direction of approaching the leakage detector through the bent square rod, so that the elastic top connection component contacts the corresponding side of the leakage detector, and the clamping effect of the leakage detector can be improved by the cooperation of the displacement spring and the buffer rubber pad, thereby achieving the limitation and fixation of the leakage detector, completing the installation operation of the leakage detector, avoiding the shaking of the leakage detector due to other factors during use, and improving the stability of the leakage detector during use.

[0028] 3. The cleaning scraper in the present invention can reciprocate on the top surface of the leakage detector, so that the rubber part on the cleaning scraper contacts the sensing signal end on the top surface of the leakage detector and reciprocates, thereby cleaning the dust adhered or accumulated on the sensing signal end, avoiding the leakage detector being exposed to the outside world for a long time, resulting in a lot of dust covering its signal end and affecting the normal use of the instrument, thereby avoiding false alarms or signal interference, improving the detection accuracy of the device, and improving the use effect.

[0029] 4. In the present invention, since the contact surface between the cleaning scraper and the leakage detector is made of rubber material, it can prevent the cleaning scraper from being damaged due to excessive rigid contact force or accidental damage to the sensing signal end face during the process of cleaning the dust covered on the sensing signal end, thereby avoiding affecting the normal use of the device and improving the use effect of the device. The rubber material has a certain flexibility and can better fit the top surface of the leakage detector, and can effectively absorb impact force, thereby reducing damage to the sensing signal end face during the cleaning process, and can effectively protect the cleaning scraper and the sensing signal end face.

[0030] 5. In the present invention, when the two electric telescopic rods work and drive the corresponding U-shaped square plates to move back and forth, the U-shaped square plates drive the positioning round rods to move back and forth in the corresponding positioning cylinders. When the positioning round rods move back and forth in the positioning cylinders, the gas in the positioning cylinders is continuously transported to the conveying air pipe, and the gas in the conveying air pipe is ejected through the high-pressure nozzle, so that the output end of the high-pressure nozzle continuously ejects high-pressure gas, thereby being able to purge dust or debris adhered to the sensing signal end of the leakage detector, thereby improving the cleaning effect at the sensing signal end.

[0031] 6. In the process of jetting, the high-pressure nozzle in the present invention will continuously spray water mist, and the gas sprayed from the high-pressure nozzle will spray the water mist on the sensing signal end, thereby increasing the spraying range, and with the cooperation of the cleaning scraper, the sensing signal end can be deeply cleaned, thereby improving the use effect, thereby improving the detection effect and accuracy.

DETAILED DESCRIPTION

[0042] like Figure 1-Figure 8 As shown, a leakage detection device for building facilities includes a loading box 1, a slot is provided on the top surface of the loading box 1, a leakage detector 2 is installed in the slot, the leakage detector 2 is used to detect whether leakage occurs in the circuit around the equipment, the loading box 1 is fixedly installed in the area to be detected by bolts, and an execution locking unit for fixing the leakage detector 2 is provided on the loading box 1; a reciprocating cleaning mechanism for cleaning the induction signal end at the top surface of the leakage detector 2 is provided above the leakage detector 2, and a driving component for driving the reciprocating cleaning mechanism to work is provided below the loading box 1.

[0043] The execution locking unit includes a displacement cross plate 41 arranged at the upper position on both sides of the loading square box 1, and an elastic top connection component is arranged on the side of the displacement cross plate 41 close to the loading square box 1. A rotating shaft 3 is rotatably installed on the front side of the loading square box 1, and a rotating gear 5 is fixedly installed on the rotating shaft 3. The upper and lower sides of the rotating gear 5 are respectively meshed and connected with rotating racks 33. The rotating racks 33 are slidably installed on the loading square box 1 through an elastic sliding unit, and the ends of the two rotating racks 33 that are away from each other are fixedly connected to the corresponding displacement cross plates 41 through a bent square rod 40.

[0044] In this embodiment, a bearing seat is provided at the connection between the rotating shaft 3 and the loading box 1, and the rotating shaft 3 is rotatably mounted on the loading box 1 through the bearing seat, which is convenient for assembly and installation.

[0045] In this embodiment, a rotating handle 4 is fixedly mounted on one end of the rotating shaft 3 away from the loading square box 1 , and the rotating shaft 3 can be controlled to rotate by rotating the handle 4 , which is convenient for use.

[0046] The elastic top connection assembly includes two displacement slide bars 42 symmetrically arranged and slidably mounted on a displacement cross plate 41 , one end of the two displacement slide bars 42 close to the loading square box 1 is fixedly connected to the same locking square plate 44 , and the other ends of the two displacement slide bars 42 are connected to a displacement limit plate 43 .

[0047] The displacement slide bar 42 is sleeved with a displacement spring 45 , one end of the displacement spring 45 is connected to the displacement horizontal plate 41 , and the other end of the displacement spring 45 is connected to the locking square plate 44 .

[0048] In this embodiment, a buffer rubber pad 46 is provided on one side of the locking square plate 44 close to the loading square box 1 , and the buffer rubber pad 46 contacts the corresponding side of the leakage detector 2 .

[0049] The elastic sliding unit includes a rotating square plate 34 fixedly mounted on the two ends of the rotating rack 33, a rotating square column 35 is fixedly connected between the two rotating square plates 34, a rotating base plate 36 is slidably connected to the rotating square column 35, and the rotating base plate 36 is fixedly mounted on the loading square box 1; the rotating base plate 36 is used to support the rotating square column 35 to move.

[0050] The rotating square column 35 is sleeved with a rotating spring 37 , one end of the rotating spring 37 is connected to the rotating base plate 36 , and the other end is connected to the corresponding rotating square plate 34 .

[0051] In this embodiment, one end of the bent square rod 40 away from the displacement horizontal plate 41 is fixedly mounted on the corresponding rotating square plate 34 .

[0052] In addition to the present embodiment, the number of the rotating substrates 36 can also be multiple, and the multiple rotating substrates 36 are arranged along the moving trajectory of the rotating square column 35 and the bending square rod 40, and the multiple rotating substrates 36 are fixedly installed on the loading square box 1, and the rotating substrates 36 are slidably connected to the corresponding bending square rod 40. At this time, the rotating square column 35 and the bending square rod 40 can be supported to move by the multiple rotating substrates 36, which is convenient to use.

[0053] With this design, when using the building facility leakage detection device to detect the circuit near the equipment, it is only necessary to fix the loading box 1 with bolts near the detection area, and then place the leakage detector 2 required for the detection in the slot of the loading box 1, so that the leakage detector 2 can detect whether there is leakage in the circuit at the current position for a long time, avoiding safety problems caused by the operator being too close to the leakage area due to holding or other behaviors, thereby ensuring the physical and mental health of the operator and improving the safety of the device when in use.

[0054] When the leakage detector 2 is placed in the loading square box 1 and needs to be fixed, the operator can hold the rotating handle 4 to control the rotating shaft 3 to rotate, which can drive the rotating gear 5 to rotate; the rotation of the rotating gear 5 drives the two rotating racks 33 to move in the direction of approaching each other, at this time, the rotating square column 35 moves to the upper limit on the rotating base plate 36, and the rotating spring 37 is in a buffering state. At this time, the two rotating racks 33 move through the bent square rod 40 to drive the displacement cross plate 41 to move in the direction close to the leakage detector 2.

[0055] The movement of the displacement transverse plate 41 drives the locking square plate 44 to move. At this time, the locking square plate 44 drives the buffer rubber pad 46 to contact the corresponding side of the leakage detector 2. The displacement transverse plate 41 continues to move and compresses the displacement spring 45 to store force under the reaction force of the leakage detector 2, thereby improving the clamping effect of the leakage detector 2, thereby limiting and fixing the leakage detector 2, completing the installation operation of the leakage detector 2, avoiding the shaking of the leakage detector 2 due to other factors during use, and improving the stability of the leakage detector 2 during use.

[0056] In addition, the displacement spring 45 and the buffer rubber pad 46 can increase the strength of the locking square plate 44 when in contact with the leakage detector 2. The buffer rubber pad 46 can also increase the friction force when the leakage detector 2 and the locking square plate 44 are in contact, further improving the installation effect of the leakage detector 2 and avoiding the dislocation of the installed leakage detector 2 during use. The installation process is convenient and quick, and the installation operation can be completed without the aid of any tools, which reduces the limitations of the device during use and improves the use effect of the device.

[0057] In addition to this embodiment, the driving source of the rotating shaft 3 can also be set to be a motor drive. The motor is installed on the loading box 1 through a mounting frame. The power output end of the motor is transmission-connected to the rotating shaft 3. The motor is used to drive the rotating shaft 3 to rotate, so that the rotation of the rotating shaft 3 is automated and convenient to use.

[0058] In this embodiment, a meshing stop assembly for limiting the position of the rotating gear 5 is provided on one side of the rotating gear 5 .

[0059] The meshing stop assembly includes a stop transverse plate 23 fixedly mounted on the loading box 1 and located on one side of the rotating gear 5, and two stop slide bars 24 are slidably connected to the stop transverse plate 23. The two stop slide bars 24 are symmetrically arranged, and one end of the two stop slide bars 24 close to the rotating gear 5 is fixedly connected to the same stop tooth block 26, and the other end of the stop slide bar 24 is fixedly connected to the same stop limit plate 25.

[0060] The stop slide bar 24 is sleeved with a stop spring 27 , one end of the stop spring 27 is connected to the stop limit plate 25 , and the other end of the stop spring 27 is connected to the stop transverse plate 23 .

[0061] With this design, when it is necessary to make the rotating shaft 3 drive the rotating gear 5 to rotate, the stop limit plate 25 can be pulled, and the stop limit plate 25 drives the stop tooth block 26 to move to the side away from the rotating gear 5 through the stop slide rod 24. At this time, the stop tooth block 26 releases the limit on the rotating gear 5, thereby enabling the rotating shaft 3 and the rotating gear 5 to rotate normally.

[0062] When it is necessary to limit the rotation of the rotating gear 5, the stop limit plate 25 can be loosened. At this time, under the pulling force of the stop spring 27, the stop limit plate 25 drives the stop tooth block 26 to move to the side close to the rotating gear 5 through the stop slide rod 24, so that the stop tooth block 26 is engaged with the rotating gear 5. At this time, the circumferential rotation of the rotating gear 5 can be limited by the stop tooth block 26, which is convenient for use.

[0063] It is worth mentioning that: when the locking unit completes the fixing operation of the leakage detector 2, and the stop tooth block 26 on the meshing stop assembly limits the rotating gear 5, since the rotating spring 37 cannot be reset, the elastic force brought about strengthens the friction between the side of the rotating gear 5 and the side of the stop tooth block 26, further enhancing the limiting effect of the stop tooth block 26 on the rotating gear 5, avoiding the movement of the stop tooth block 26, and improving the use effect of the device.

[0064] The driving assembly includes a T-shaped square plate 20 fixedly mounted on the bottom surface of the loading square box 1 , electric telescopic rods 21 are fixedly mounted on both sides of the T-shaped square plate 20 away from each other, and a U-shaped square plate 22 is mounted on the output end of the electric telescopic rod 21 .

[0065] With such a design, the electric telescopic rod 21 works to extend or retract its telescopic end, and at this time, the telescopic end of the electric telescopic rod 21 can drive the corresponding U-shaped square plate 22 to move, which is convenient for use.

[0066] The reciprocating dust cleaning mechanism comprises an extended square rod 18 arranged on one side of the loading square box 1. The upper end of the extended square rod 18 is bent and arranged on the top surface of the leakage detector 2 and is fixedly connected to a cleaning scraper 19 through a connecting rod.

[0067] In this embodiment, the cleaning scraper 19 contacts the sensing signal end at the top surface of the leakage detector 2, and the contact surface of the cleaning scraper 19 is made of rubber.

[0068] A driving substrate 9 is fixedly installed on one side surface of the loading square box 1 close to the extended square rod 18, and a driving shaft 8 is rotatably connected to the driving substrate 9. One end of the driving shaft 8 is located at the front side of the loading square box 1 and is fixedly connected to a driving gear 7. An engaging rack 47 is meshedly connected above the driving gear 7. The engaging rack 47 is fixedly installed on the L-shaped square rod 6, and one end of the L-shaped square rod 6 is fixedly installed on the corresponding U-shaped square plate 22.

[0069] The loading box 1 is rotatably connected to an auxiliary shaft 12 on one side close to the driving shaft 8. The auxiliary shaft 12 is connected to the driving shaft 8 via a bevel gear set. A reciprocating disc 13 is fixedly connected to the other end of the auxiliary shaft 12.

[0070] In this embodiment, the bevel gear set includes a first bevel gear 10 fixedly mounted on an end of the driving shaft 8 away from the driving gear 7, and a second bevel gear 11 is fixedly mounted on the auxiliary shaft 12 near the first bevel gear 10, and the second bevel gear 11 is meshingly connected with the first bevel gear 10.

[0071] A reciprocating cylinder 14 is eccentrically mounted on one side of the reciprocating disc 13 away from the loading box 1, a reciprocating cross block 15 is slidably sleeved on the reciprocating cylinder 14, the reciprocating cross block 15 is slidably connected to the loading box 1 through a guide rod assembly, and the lower end of the extended square rod 18 is fixedly mounted on the reciprocating cross block 15.

[0072] The guide rod assembly includes two guide round rods 16 fixedly mounted on one side of the double-moving horizontal block 15 . The two guide round rods 16 are symmetrically arranged. The two guide round rods 16 are slidably connected to the same guide base plate 17 , which is fixedly mounted on the driving base plate 9 .

[0073] With such a design, the guide round rod 16 cooperates with the guide base plate 17 to guide the movement of the double-moving cross block 15, so that the double-moving cross block 15 can achieve horizontal movement, which is convenient for use.

[0074] With this design, when the leakage detector 2 is used for too long, more dust will accumulate on its sensing signal end, affecting the accuracy of the detection result, and then the sensing signal end of the leakage detector 2 needs to be cleaned. When cleaning is needed, the electric telescopic rod 21 is first started, and the electric telescopic rod 21 drives the corresponding U-shaped square plate 22 to move back and forth. At this time, the U-shaped square plate 22 drives the meshing rack 47 to move back and forth through the L-shaped square rod 6, and the meshing rack 47 drives the driving gear 7 and the driving shaft 8 to rotate back and forth. The driving shaft 8 drives the auxiliary shaft 12 and the compound moving disc 13 to rotate through the transmission action of the first bevel gear 10 and the second bevel gear 11. At this time, the compound moving cylinder 14 reciprocates in the compound moving cross block 15 and moves the compound moving cross block 15 through the cooperation of the guide rod assembly. The compound moving cross block 15 drives the cleaning scraper 19 to move back and forth on the top surface of the leakage detector 2 through the extended square rod 18 to clean the dust;

[0075] When the cleaning scraper 19 moves, the rubber part on the cleaning scraper 19 contacts the sensing signal end on the top surface of the leakage detector 2 and moves back and forth, thereby cleaning the dust accumulated on the sensing signal end, preventing the leakage detector 2 from being exposed to the outside world for a long time, causing its signal end to be covered with a lot of dust and affecting the normal use of the instrument, thereby avoiding false alarms or signal interference, and improving the accuracy of the detection results.

[0076] In this embodiment, the contact surface between the cleaning scraper 19 and the leakage detector 2 is made of rubber material, which can prevent the cleaning scraper 19 from being damaged due to excessive rigid contact force or accidental damage to the sensing signal end surface during the process of cleaning the dust covered on the sensing signal end, thereby affecting the normal use of the device, reducing the limitations of the device during use, and improving the use effect of the device. In addition, the surface has a certain flexibility, can better fit the top surface of the leakage detector 2, and can effectively absorb impact force, reduce damage to the sensing signal end surface during the cleaning process, and can effectively protect the sensing signal end surface.

[0077] Positioning rods 28 are symmetrically mounted on one side of the two U-shaped square plates 22 that are close to each other. Positioning cylinders 29 are sleeved on the outside of the positioning rods 28 . The positioning cylinders 29 are mounted on the loading box 1 .

[0078] A positioning spring 30 is fixedly installed in the positioning cylinder 29 , and the other end of the positioning spring 30 is fixedly connected to the positioning round rod 28 .

[0079] The positioning cylinder 29 is connected to a delivery air pipe 31, and the air outlet end of the delivery air pipe 31 is located on the top surface of the leakage detector 2; a high-pressure nozzle 32 is also installed on the air outlet end of the delivery air pipe 31; the output ends of multiple high-pressure nozzles 32 are all facing the sensing signal end on the top surface of the leakage detector 2.

[0080] In this embodiment, a sprayer 38 is further installed at the high-pressure nozzle 32 , and the water mist sprayed from the output end of the sprayer 38 is located at the output end of the high-pressure nozzle 32 .

[0081] A plurality of auxiliary bases 39 are fixedly mounted on the air delivery pipe 31 , and the auxiliary bases 39 are fixedly mounted on the loading box 1 ; the auxiliary bases 39 are used to support and install the air delivery pipe 31 .

[0082] In this embodiment, an air inlet is opened on the positioning cylinder 29, and a first one-way valve is installed at the air inlet. External gas can enter the positioning cylinder 29 through the first one-way valve and the air inlet, and the gas in the positioning cylinder 29 cannot be discharged to the outside through the air inlet and the first one-way valve.

[0083] A second one-way valve is installed at the connection between the delivery air pipe 31 and the positioning cylinder 29. The gas in the positioning cylinder 29 is delivered to the delivery air pipe 31 through the second one-way valve, and the gas in the delivery air pipe 31 cannot enter the positioning cylinder 29 through the second one-way valve.

[0084] With such a design, when the two electric telescopic rods 21 work and drive the corresponding U-shaped square plates 22 to move back and forth, the U-shaped square plates 22 drive the positioning round rods 28 to move back and forth in the corresponding positioning cylinders 29. When the positioning round rods 28 move back and forth in the positioning cylinders 29, the gas in the positioning cylinders 29 is continuously transported to the delivery air pipe 31, and the gas in the delivery air pipe 31 is ejected through the high-pressure nozzle 32, so that the output end of the high-pressure nozzle 32 continuously ejects high-pressure gas, thereby being able to purge dust or debris adhered to the sensing signal end of the leakage detector 2, thereby improving the cleaning effect at the sensing signal end.

[0085] During the spraying process of the high-pressure nozzle 32, the sprayer 38 will continuously spray water mist, and the gas sprayed by the high-pressure nozzle 32 will spray the water mist on the sensing signal end, thereby increasing the spraying range, and with the cooperation of the cleaning scraper 19, the sensing signal end can be deeply cleaned, thereby improving the use effect, thereby improving the detection effect and accuracy.

[0086] In this embodiment, the U-shaped square plate 22 drives the positioning rod 28 to move within the positioning cylinder 29 during movement, so that the positioning spring 30 is in a buffer state, which is used to assist the electric telescopic rod 21 in resetting and improving the use effect.

[0087] The present invention also provides a method for using a building facility leakage detection device, based on the above-mentioned building facility leakage detection device, comprising the following steps:

[0088] S1. The loading box 1 is fixedly installed near the detection area by means of bolts, and the leakage detector 2 required for detection is placed into the notch of the loading box 1.

[0089] S2. Then, the meshing stop assembly releases the restriction on the rotating gear 5, and the rotating shaft 3 is rotated to drive the rotating gear 5 to rotate. The rotation of the rotating gear 5 causes the two rotating racks 33 to move toward each other. The rotating rack 33 drives the displacement cross plate 41 to move toward the leakage detector 2 through the bent square rod 40. At this time, the elastic top connection assembly contacts and fixes the leakage detector 2. After the fixation is completed, the stop tooth block 26 of the meshing stop assembly is engaged with the rotating gear 5 to limit the rotating gear 5.

[0090] In step S2, the working process of the meshing stop assembly is: pull the stop limit plate 25, the stop limit plate 25 drives the stop tooth block 26 to move to the side away from the rotating gear 5 through the stop slide rod 24, and at this time the stop tooth block 26 releases the limit on the rotating gear 5, thereby enabling the rotating shaft 3 and the rotating gear 5 to rotate normally.

[0091] When the stop limit plate 25 is released, under the pulling force of the stop spring 27, the stop limit plate 25 drives the stop tooth block 26 to move toward the side close to the rotating gear 5 through the stop slide rod 24, so that the stop tooth block 26 is engaged with the rotating gear 5 to limit the circumferential rotation of the rotating gear 5, which is convenient for use.

[0092] In step S2, the working process of the elastic top connection assembly is: the movement of the displacement cross plate 41 drives the locking square plate 44 to move. At this time, the locking square plate 44 drives the buffer rubber pad 46 to contact the corresponding side of the leakage detector 2. The displacement cross plate 41 continues to move and compresses the displacement spring 45 under the reaction force of the leakage detector 2 to improve the clamping effect of the leakage detector 2, thereby achieving the limitation and fixation of the leakage detector 2.

[0093] In addition, the displacement spring 45 and the buffer rubber pad 46 can increase the strength of the locking square plate 44 when in contact with the leakage detector 2. The buffer rubber pad 46 can also increase the friction force of the leakage detector 2 when in contact with the locking square plate 44, further improving the installation effect of the leakage detector 2.

[0094] S3. The operator observes the data transmitted by the leakage detector 2 for long-term detection of whether leakage occurs in the area.

[0095] S4. When it is necessary to clean the dust on the sensing signal end of the leakage detector 2, first control the two electric telescopic rods 21 to work and drive the corresponding U-shaped square plate 22 to move back and forth. At this time, the U-shaped square plate 22 drives the meshing rack 47 to move back and forth through the L-shaped square rod 6, and the meshing rack 47 drives the driving gear 7 and the driving shaft 8 to rotate back and forth. The driving shaft 8 drives the auxiliary shaft 12 and the compound moving disc 13 to rotate through the bevel gear set. At this time, the compound moving cylinder 14 moves back and forth in the compound moving cross block 15 and moves the compound moving cross block 15 through the cooperation of the guide rod assembly. The compound moving cross block 15 drives the cleaning scraper 19 to move back and forth on the top surface of the leakage detector 2 through the extended square rod 18 to clean the dust.

[0096] In step S4, the working process of the bevel gear set is: the driving shaft 8 rotates to drive the first bevel gear 10 to rotate, the first bevel gear 10 is meshed and connected with the second bevel gear 11, and the rotation of the first bevel gear 10 drives the auxiliary shaft 12 and the compound disk 13 to rotate through the transmission effect of the second bevel gear 11.

[0097] S5. When the two electric telescopic rods 21 work and drive the corresponding U-shaped square plates 22 to move back and forth, the U-shaped square plates 22 drive the positioning round rods 28 to move back and forth in the corresponding positioning cylinders 29, and the gas in the positioning cylinders 29 is ejected from the high-pressure nozzles 32 through the air delivery pipes 31 and blown toward the sensing signal end of the leakage detector 2 to achieve dust removal; and the sprayer 38 sprays water mist, and with the cooperation of the water mist, the sensing signal end is deeply cleaned.

[0098] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
