Description

Technical Field

[0001] The present invention relates to the technical field of maintenance-free desiccant, in particular to a convenient installation device and installation method for a maintenance-free desiccant for a transformer. Background Art

[0002] Transformer breathers, also known as transformer desiccant or transformer dryers, are commonly found on large and medium-sized transformers used in power grids. These breathers are glass containers filled with hygroscopic materials such as color-changing silica gel. They filter out dust and moisture from the air, allowing pure air to enter the transformer and prevent aging of the transformer's insulating oil.

[0003] Transformer breather disassembly and assembly involves removing and installing the screws that secure the breather at the top. Normally, the breather is suspended and fixed to the transformer by these screws. Due to the current lack of specialized fixing devices, the screws loosen during disassembly and assembly, causing the breather to lose its secure hold, resulting in shaking during disassembly and assembly, hindering the removal and assembly of the screws. Therefore, the coordinated operation of multiple personnel is required. When the breather is high off the ground and heavy, the lack of specialized fixing devices makes it difficult for humans to maintain a stable fixed position for long periods of time. The shaking of the breather without effective support increases the time required to remove the screws, which in turn increases the difficulty of manual support. This vicious cycle makes screw removal and assembly difficult and also poses the safety risk of the breather falling and breaking.

[0004] Therefore, it is necessary to provide a convenient installation device and installation method for a transformer maintenance-free desiccant, which can quickly and conveniently install the transformer breather and can perform sealing detection on the installed transformer breather to ensure normal use.

[0043] It should be noted that the respirator has good sealing performance. When the respirator does not need to be used for exhalation and inhalation, the pressure value detected by the pressure sensor is the air pressure value.

[0044] The mobile trolley 1 adopts a motor to drive the body to move and a cylinder to drive it to rise and fall. When in use, the staff drives the mobile trolley 1 to move and stop by turning the handle, and then controls the lifting and stopping of the top panel of the mobile trolley 1 by operating the switch on the handle.

[0045] like Figure 2 and Figure 3 As shown, the clamping assembly 2 includes a cylinder 21, which is fixed to the top of the mobile trolley 1, and a connecting tube 22 is fixedly connected to the top of the cylinder 21.

A rubber pad 1 is provided in the groove 1. The bottom of the connecting base plate 25 is fixedly connected to the spring 23. The bottom of the connecting base plate 25 is slidably connected to a slider 1. The slider 1 is provided with four groups, and the slider 1 is hinged. The clamping rod 26 is L-shaped and is hinged to the top of the connecting tube 22. A gasket is fixedly connected to the clamping rod 26. When in use, the bottom of the respirator is placed on the connecting base plate 25. Under the action of the gravity of the respirator, the spring 23 is compressed, driving the connecting base plate 25 to slide up and down on the guide column 24. At the same time, the clamping rod 26 close to the side of the guide column 24 is pressed down, so that the clamping rod 26 rotates around the hinge with the connecting tube 22, and the top of the clamping rod 26 fits the respirator, thereby clamping and fixing the bottom of the respirator 7, and then using the cylinder 21 to start the telescopic control of the lifting height of the respirator 7.

[0046] like Figure 2 、 Figure 4-Figure 9As shown, the support assembly 3 includes a support frame 31, a sliding door 32 and a locking mechanism. The support frame 31 is fixed on the top of the mobile trolley 1, and the sliding door 32 is symmetrically arranged in two groups. The sliding door 32 is slidably connected to the support frame 31, and the inner side of the sliding door 32 is arranged to be arc-shaped. The top and side of the arc part of the sliding door 32 are rotatably connected with the ball 33. When in use, when the clamping assembly 2 is fixed and the respirator is raised to a suitable height, the two groups of sliding doors 32 are slid toward each other so that the ball 33 of the arc part of the sliding door 32 fits the respirator, restricting the position of the top flange of the respirator and further fixing the respirator. If the direction of the respirator needs to be adjusted, the cylinder 21 of the clamping assembly 2 is controlled to retract to release the fixation of the bottom of the respirator. At this time, the top flange of the respirator is located above the ball 33 on the sliding door 32, and the respirator 7 is rotated. Under the rolling action of the ball 33, the direction of the respirator can be conveniently adjusted, and it is flexible to use.

[0047] like Figure 4 - Figure 9 As shown, there are two groups of locking mechanisms, which are respectively located on both sides of the sliding door 32. The locking mechanisms include a connector 34, a second spring 35 and a lock catch 36. The connector 34 is hinged to the top of one group of sliding doors 32, and the two ends of the second spring 35 are fixedly connected to the connector 34 and the lock catch 36 respectively. A limiting groove is provided on the top of the other group of sliding doors 32. The limiting groove is provided with several groups. A slider 2 37 is slidably connected in the limiting groove. A locking rod is fixedly connected to the top of the slider 2 37. The locking rod is used to limit the position of the lock catch 36 and play a locking role. A limiting rod is fixedly connected to the slider 2 37. The limiting rod is L-shaped as a whole and passes through the slider 2 37 at both ends. A straight slot 38 and a round slot 39 are also provided on the sliding door 32. The straight slot 38 and the limiting rod The upper and lower movable positions are consistent, which is used to limit the movable area of ​​the limit rod. There are two groups of circular grooves 39. The arc position and radius of the upper and lower parts of the circular grooves 39 and the straight slots 38 are equal. When in use, slide the sliding door 32 according to the size of the respirator to be installed to limit the position of the respirator. Select the slider 2 37 with the corresponding size of the respirator, first pull the limit rod to the right, pull the limit rod out from the circular groove 39 below, and then pull the limit rod upward to drive the slider 2 37 to slide up until the limit rod is at the top of the straight slot 38, press the limit rod, insert the limit rod into the circular groove 39 above, complete the limit of the slider 2 37, and then pull the lock buckle 36 to drive the spring 2 35 to stretch, and put the lock buckle 36 on the lock rod to complete the locking of the sliding door 32.

[0048] It should be noted that the second spring 35 is a hard spring used to limit the movement of the sliding door 32 to ensure that the sliding door 32 can be fixedly supported and limit the respirator.

[0049] like Figure 2 and Figure 4As shown, the drive assembly 4 includes a motor 41, a screw 42 and a drive platform 43. The motor 41 and the screw 42 are connected by a bevel gear transmission. The screw 42 is threadedly connected to the drive platform 43. When the motor 41 is started, the drive platform 43 is driven to move up and down. The drive platform 43 is fixedly connected to the motor 2 44. The output end of the motor 2 44 is gear-connected to the large gear 45. When the motor 2 44 is started, the large gear 45 is driven to rotate through the gear transmission.

[0050] like Figure 1 and Figure 10 As shown, the gluing assembly 5 includes a connecting seat, a camera 53 and an automatic gluing gun 54. The connecting seat is fixed to the inner ring of the large gear 45. The connecting seat is fixedly connected to an electric telescopic rod 51. The end of the electric telescopic rod 51 is fixedly connected to a connecting block 52. The camera 53 and the automatic gluing gun 54 are fixed on the connecting block 52. The electric telescopic rod 51 is extended and retracted to drive the camera 53 and the automatic gluing gun 54 on the connecting block 52 to move closer to or away from the respirator to be installed, thereby realizing the inspection and gluing operations on the sealing part of the respirator.

[0051] like Figure 4 As shown, the sealing detection component 6 includes an air pump 61 and a sealing head 62. A groove 2 is provided on the sealing head 62, and a rubber pad 2 is fixedly connected in the groove 2. The air pump 61 is connected to the top of the sealing head 62 and the bottom of the guide column 24 through a pipeline. The air pump 61 is used to pump in or out gas from the respirator. When the sealing head 62 is connected to the top of the respirator, it simulates the exhalation and inhalation of the respirator to ensure that the respirator is well sealed and can be used normally.

[0052] The installation system includes an acquisition module, a control module and an alarm module. The acquisition module is electrically connected to the pressure sensor and the camera 53. The acquisition module is provided with a pressure limit and image recognition. The acquisition module is used to collect the actual internal pressure data of the respirator and the usage of the rubber strip on the surface of the respirator and perform pressure comparison and image recognition. The control module is electrically connected to the driving component 4, the gluing component 5 and the mobile cart 1. The control module is used to control and adjust the position and height of the installation equipment and the position and gluing of the automatic gluing gun 54. The alarm module is used for alarm prompts.

[0053] Installation method of transformer maintenance-free desiccant:

[0054] Step 1: Place the respirator on the equipment.

[0055] Specifically, the bottom of the respirator is placed on the connecting base plate 25, and the spring 1 23 is compressed under the action of the gravity of the respirator, driving the connecting base plate 25 to slide up and down on the guide column 24, and at the same time, the clamping rod 26 close to the side of the guide column 24 is pressed down, so that the clamping rod 26 rotates around the hinge with the connecting tube 22, and the upper part of the clamping rod 26 fits the respirator to clamp and fix the bottom of the respirator 7, and then the cylinder 21 is used to start the telescopic control to raise the respirator 7 to the required height. According to the size of the respirator to be installed, the two sets of sliding doors 32 are slid closer to the opposite side so that the arc of the sliding door 32 is The ball bearing 33 of the shaped portion fits the respirator, restricting the position of the respirator's top flange and further securing the respirator. A second slider 37 of the appropriate size for the respirator is selected. The limiting rod is first pulled rightward to remove it from the circular groove 39 below. The limiting rod is then pulled upward, driving the second slider 37 to slide upward until the limiting rod is at the top of the straight notch 38. The limiting rod is then pressed to insert it into the circular groove 39 above, securing the second slider 37. The lock catch 36 is then pulled, causing the second spring 35 to stretch, causing the lock catch 36 to fit over the lock rod, thus locking the sliding door 32. If the direction of the respirator needs to be adjusted, the cylinder 21 of the clamping assembly 2 is controlled to retract, releasing the fixation on the bottom of the respirator. At this point, the top flange of the respirator is located above the ball bearing 33 at the top of the sliding door 32. The respirator 7 is then rotated. The rolling action of the ball bearing 33 allows the respirator to be easily adjusted in direction, providing flexibility and stability, without the need for manual support of the respirator to be installed.

[0056] Step 2: Check the sealing before installation.

[0057] Specifically, the staff connects the sealing head 62 to the top of the respirator. At this time, the bottom of the respirator contacts the rubber pad 1 on the connecting bottom plate 25, and the top of the respirator contacts the rubber pad 2 on the sealing head 62, so that a closed space is formed inside the respirator for pressure comparison. During the pressure comparison, the control module controls the air pump 61 to start, simulates the breathing state of the respirator and keeps the internal pressure of the respirator at the pressure limit, maintains the pressure for a certain period of time, and the acquisition module continuously collects the pressure value detected by the pressure sensor. After a certain period of time, if the internal pressure exceeds the 0.9 pressure limit, the respirator has good sealing and can be installed and used normally. If the internal pressure of the respirator does not exceed the 0.9 pressure limit, the respirator has poor sealing. First, the staff checks and adjusts the connection between the top and bottom of the respirator and the rubber pad, and then repeats this step to avoid reduced sealing due to abnormal connection with the rubber pad. If the internal pressure of the respirator still does not exceed the 0.9 pressure limit after detection, it is caused by abnormal sealing of the respirator itself. The staff controls motor 1 41 and motor 2 44 to start and drive the glue. Component 5 is lifted and rotated to the position where the respirator is provided with sealant, and the acquisition module collects the picture taken by the camera 53 and identifies whether there are cracks, warping, bulging, etc. in the sealant in the picture. If there are cracks, warping, bulging, etc., it is due to abnormal sealant causing poor sealing of the respirator, and a gluing operation is required. After the gluing operation, after the sealant is dry, this step still needs to be repeated to ensure that the respirator has good sealing after gluing. If the internal pressure of the respirator still does not exceed the 0.9 pressure limit after the gluing operation, it is caused by abnormal connection of the internal respirator or damage to components, which is fed back to the alarm module and the staff will replace the respirator. If there are no cracks, warping, bulging, etc. in the identification picture, it is caused by abnormal connection of the internal respirator or damage to components, which is fed back to the alarm module and the staff will replace the respirator.

[0058] Step 3: Install the respirator.

[0059] Specifically, the staff controls the oil cylinder on the mobile trolley 1 to start, driving the top panel of the mobile trolley 1 to rise until the top of the respirator is flush with the bottom of the transformer oil pillow flange. The staff then fine-tunes the position of the mobile trolley 1 and the direction of the respirator so that the mounting holes on the respirator correspond to the positions of the mounting holes on the oil pillow flange. The connecting bolts are inserted into the mounting holes and fastened with nuts to complete the installation operation. There is no need to use manpower to support the respirator to be installed, and the labor intensity is low, the operation is portable, and the safety is high.

[0060] Step 4: Install the respirator and then test its tightness.

[0061] Specifically, the control cylinder 21 is extended so that the rubber pad on the connecting base plate 25 contacts the bottom of the respirator, and the pressure comparison is repeated. At this time, if the internal pressure exceeds the pressure limit of 0.9, it means that the sealing of the connection between the top flange of the respirator and the oil pillow flange is good and the installation is normal; if the internal pressure of the respirator does not exceed the pressure limit of 0.9, it means that the sealing of the connection between the top flange of the respirator and the oil pillow flange is poor, and an alarm is issued. The staff will disassemble the respirator and repeat step three to install the respirator to ensure normal installation. After repetition, if the internal pressure of the respirator still does not exceed the pressure limit of 0.9, it will be fed back to the alarm module, and the staff will check whether the oil pillow flange is deformed or damaged.

[0062] Gluing operation: Control the gluing component 5 to rise and fall and rotate to the position where the sealant has cracks, warping, bulging, etc., control the electric telescopic rod 51 to extend so that the gun head of the automatic gluing gun 54 fits the sealant, and then control the automatic gluing gun 54 to start and perform gluing operations on the cracks, warping, bulging, etc.

[0063] It should be noted that this installation equipment is also suitable for daily maintenance and inspection of respirators, and the operating steps during daily maintenance and inspection are consistent with step four; it can also be used for the connection and installation of respirators inside the workshop. At this time, the clamping component 2 fixes the clamping connection base plate 25, and then the components inside or above the respirator are placed one by one on the connection base plate 25. The staff connects the components or the control module controls the gluing component 5 to perform gluing operations on the connection points. After that, a pressure sensor is placed inside the newly installed component, and the sealing head 62 is used to connect the newly installed component. The air pump 61 is controlled to start, which can be used for pressure comparison to ensure that each newly connected component has good sealing and has wide applicability.

[0064] Through the above steps, the respirator can be installed conveniently, the labor intensity of the installer can be reduced, the sealing of the respirator before and after installation can be tested, and the sealant test and gluing operation can be performed when the sealing of the respirator is poor to ensure that the respirator can work normally.
