Description

Technical Field

[0001] This invention belongs to the field of electrical equipment installation technology in power construction, and specifically relates to a GIS flange docking and positioning device. Background Technology

[0002] As a core component of the power system, GIS equipment is characterized by long installation period, complex technology, huge investment and high quality requirements. Its equipment components are often divided into multiple cylindrical sections, which are then connected on site. During installation, they are aligned and connected by GIS flanges at both ends of the cylindrical section.

[0003] The existing alignment and installation of GIS flanges involves two methods. One method is to lift the two cylinders to the installation position using a lifting tool, and then manually move and align them using guide rails and derricks. However, during manual alignment, there may be some misalignment of the flange bolt holes that is not easily observed by the naked eye. This misalignment is only discovered when the two flanges are mated and bolts are installed. If the two flanges are then aligned again, it can cause friction between the mated GIS flange surfaces, or even damage during the mating process. This can lead to dust and impurities entering the sealing surface into the cylinder, affecting installation quality and efficiency, and causing insulation failures.

[0004] Furthermore, Chinese invention patent application CN108548487A, published on September 18, 2018, entitled "A Precise Laser Alignment Device for GIS Equipment," aligns the flanges of two busbar cylinders by installing laser transmitters and receivers circumferentially on two different busbar cylinders. The laser receivers receive the laser signals from the transmitters to ensure the alignment of the cylinder flanges. However, this alignment device requires the laser receiver to be installed directly above the bolt holes on the cylinders, and also directly above the bolts. This means the relative positions of the laser transmitter and the bolt holes must be identical to the relative positions of the laser receiver and the bolts. Only when the laser transmitter and receiver are aligned can the bolt holes and bolts align. This necessitates measuring the distances of the laser transmitter and receiver relative to the bolt holes and bolts during installation to ensure consistency. This measurement is required for each pair of GIS flanges installed, significantly increasing construction time and extending the installation cycle. Moreover, this laser alignment device is only suitable for misalignment adjustments where the two cylinder axes are parallel and only have a certain degree of translation in the vertical and horizontal planes; it does not consider situations where... Figure 1 As shown, when the two cylinders are axially intersected at a certain angle, the laser emitting and receiving devices on them will also be axially intersected, neither parallel nor overlapping. In this case, the laser receiving device will also be unable to receive the laser signal from the laser emitting device. However, after adjusting the cylinders so that the laser receiving device can receive the laser signal from the laser emitting device, the following may occur: Figure 2As shown, the axes of the two cylinders still do not coincide. If the two cylinders are brought close to each other and connected to the GIS flange, they still cannot be aligned, resulting in poor connection quality of the GIS flange, which affects the timely delivery of the project and the safety and stability of subsequent operation. Summary of the Invention

[0005] This invention addresses the aforementioned technical problems in the prior art by proposing a GIS flange docking and positioning device. Utilizing the existing bolt holes of the GIS flange as a positioning standard, alignment of the bolt holes can be determined simply by the laser receiver receiving a signal from the laser transmitter. This reduces the positioning and docking time of the GIS flange and shortens the installation cycle.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A GIS flange docking and positioning device includes a left and right cylindrical body arranged opposite each other, a laser emitter and a laser receiver, two elastic bands, and a controller mounted on one of the elastic bands. Each of the left and right cylindrical bodies has a GIS flange at one opposite end, and the GIS flange has multiple screw holes. The head of the laser emitter is positioned inside a screw hole in the GIS flange at the end of the left cylindrical body, and the head of the laser receiver is positioned inside a screw hole in the GIS flange at the end of the right cylindrical body. The two elastic bands are respectively fitted onto the left and right cylindrical bodies, and each elastic band has a movable collar. The body of the laser emitter is connected to the movable collar of the elastic band on the left cylindrical body, and the body of the laser receiver is connected to the movable collar of the elastic band on the right cylindrical body. Both the laser emitter and the laser receiver are communicatively connected to the controller.

[0008] Preferably, it also includes a positioning frame, which is arranged circumferentially along the left and right cylinders.

[0009] Preferably, the positioning frame includes a first connecting rod, a second connecting rod, and a sliding rod; one end of the first connecting rod is connected to the tail of the laser emitter, and the other end is provided with a first sleeve; one end of the second connecting rod is connected to the tail of the laser receiver corresponding to the laser emitter, and the other end is provided with a second sleeve; the first sleeve and the second sleeve are coaxially arranged, and the sliding rod passes through the first sleeve and the second sleeve.

[0010] Preferably, the number of laser emitters, laser receivers, and positioning frames are all two or more.

[0011] Preferably, the controller includes a data output port and multiple data input ports; multiple laser emitters are connected to the controller's data output port, and multiple laser receivers are connected to the controller's data input ports one by one; the controller is also equipped with a display panel and a sound alarm.

[0012] Preferably, the controller is a microcontroller or a PLC.

[0013] Preferably, the head of the laser emitter is fitted into the threaded hole of the GIS flange at the left end of the cylinder through a rubber sealing plug; the head of the laser receiver is fitted into the threaded hole of the GIS flange at the right end of the cylinder through a rubber sealing plug; the rubber sealing plug is stepped.

[0014] Preferably, the body of the laser emitter is connected to the movable collar via a clamp; the body of the laser receiver is connected to the movable collar via a clamp.

[0015] Preferably, the elastic band is provided with a buckle, the buckle including a plug and a slot; one end of the elastic band is connected to the plug and the other end is connected to the slot, and the plug can be inserted into the slot.

[0016] Preferably, one end of the slide rod is provided with an external thread, and the other end is provided with an internal thread.

[0017] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0018] (1) Position the heads of the laser transmitter and the laser receiver within the screw holes of the GIS flange, using the existing screw holes as the positioning standard. When the laser receiver receives the signal from the laser transmitter, it can determine that the screw holes are aligned. There is no need to measure the position of the two relative to the screw holes, which reduces the positioning and docking time of the GIS flange and shortens the installation cycle.

[0019] (2) The elastic bands are respectively fitted on the left and right cylinders, and multiple sliding movable collars are fitted on them. The movable collars are equipped with laser emitters and laser receivers. Adjusting the position of the movable collars makes it easy for the laser emitters and laser receivers to be aligned with the screw holes. When the elastic bands are tightened on the cylinders, the movable collars are also pressed into the fixed position of the cylinders, making them easy to fix and convenient and quick to use.

[0020] (3) The controller controls the laser transmitter to emit a laser signal. When the laser receiver receives the laser signal, it feeds back a data signal to the controller. When multiple laser receivers feed back a data signal to the controller, it proves that the bolt holes of the GIS flange are aligned and the GIS flange can be connected.

[0021] (4) When the two cylinders are misaligned, the laser transmitter and laser receiver drive the two connecting rods to push outward. However, the sleeves on the connecting rods slide along the axis under the restriction of the sliding rod, and there will be no axial crossover. Therefore, the laser transmitter and laser receiver are always on a straight line, ensuring that the laser receiver can receive the signal.

[0022] (5) Both the laser transmitter and the laser receiver are pushed outward, and the distance becomes longer. The time for the laser receiver to receive the signal becomes longer, and the data signal fed back to the controller is later. By judging the timing of the data signals fed back by multiple laser receivers, it can be determined which side the two cylinders are opening to, so that the staff can make timely adjustments. This improves the docking quality of the GIS flange, enabling the project to be delivered on schedule and ensuring safety and stability in subsequent operation.

[0023] (6) The laser transmitters emit laser signals to the laser receivers together. After receiving the signals, the laser receivers feed back to the controller through different data input ports. If no signal is received, no feedback is given. The controller displays the feedback results on the display panel and controls the sound alarm to alert the staff.

[0024] (7) The rubber sealing plug is stepped and is suitable for GIS flanges with different screw hole diameters.

[0025] (8) Screw the end of one slide rod with an external thread into the end of another slide rod with an internal thread to achieve splicing between multiple slide rods, which increases the length and is suitable for positioning GIS flanges when the two cylinders are far apart.

[0045] To better understand the above-mentioned objectives, features and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0046] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0047] Example

[0048] The following is in conjunction with the appendix Figure 1-9 To further illustrate the present invention, a GIS flange docking positioning device, such as... Figure 3 , 4As shown in Figure 9, the system includes a left cylindrical body 801 and a right cylindrical body 802 arranged opposite to each other, a laser emitter 3 and a laser receiver 4, two elastic bands 1, and a controller 7 mounted on one of the elastic bands 1. Both the left cylindrical body 801 and the right cylindrical body 802 have GIS flanges 81 at opposite ends, with multiple screw holes 82 on the GIS flanges 81. The head 31 of the laser emitter 3 is located within the screw hole 82 of the GIS flange 81 at the end of the left cylindrical body 801, and the head 41 of the laser receiver 4 is located within the screw hole 82 of the GIS flange 81 at the end of the right cylindrical body 802. By using the existing screw holes 82 of the GIS flange 81 as a positioning standard, the alignment of the screw holes 82 can be determined simply by the laser receiver 4 receiving the signal from the laser emitter 3. It is not necessary to measure the position of the laser receiver 4 relative to the screw holes 82 to ensure consistency, thus reducing the positioning and docking time of the GIS flange and shortening the installation cycle.

[0049] Two elastic bands 1 are respectively fitted onto the left cylinder 801 and the right cylinder 802, and each elastic band 1 is fitted with a movable collar 2; the movable collar 2 can slide on the elastic band 1, making it easy to adjust the position of the movable collar 2. When the elastic band 1 is tightened on the cylinder, the movable collar 2 is also pressed into a fixed position on the cylinder, making it easy to fix.

[0050] The body 32 of the laser emitter 3 is connected to the movable collar 2 of the elastic band 1 on the left cylinder 801, and the body 42 of the laser receiver 4 is connected to the movable collar 2 of the elastic band 1 on the right cylinder 802. The laser emitter 3 and the laser receiver 4 are set on the movable collar 2, which is easy to adjust and easy to fix, and are then put on the cylinder by the elastic band 1. They are convenient and quick to use and can be fixed at any position on the outer periphery of the cylinder wall with the movable collar 2.

[0051] Both the laser emitter 3 and the laser receiver 4 are connected to the controller 7. The controller 7 controls the laser emitter 3 to emit a laser signal. When the laser receiver 4 receives the laser signal, it feeds back a data signal to the controller 7. When the laser receiver 4 feeds back a data signal to the controller 7, it proves that the bolt holes 82 of the GIS flange 81 are aligned and the GIS flange 81 can be connected.

[0052] like Figure 3 , 5As shown in Figure 9, it also includes a plurality of positioning frames 6 arranged circumferentially along the left cylinder 8 and the right cylinder 8; the positioning frame 6 includes a first connecting rod 61, a second connecting rod 63 and a sliding rod 65; one end of the first connecting rod 61 is connected to the tail 33 of the laser emitter 3, and the other end is provided with a first sleeve 62; one end of the second connecting rod 63 is connected to the tail 43 of the laser receiver 4 corresponding to the laser emitter 3, and the other end is provided with a second sleeve 64; the first sleeve 62 and the second sleeve 64 are coaxially arranged, and the sliding rod 65 passes through the first sleeve 62 and the second sleeve 64.

[0053] When two cylinders appear as Figure 1 As shown, when there is a certain angle of misalignment in the axial direction, the laser emitter 3 and laser receiver 4 located on the upper side are pushed outwards, causing the first connecting rod 61 and the first sleeve 62 on it, and the second connecting rod 63 and the second sleeve 64 on it to also move outwards. However, under the restriction of the sliding rod 65, the first sleeve 62 and the second sleeve 64 always slide along the axis of the sliding rod 65 and will not intersect axially. Therefore, the laser emitter 3 and the laser receiver 4 under the first connecting rod 61 and the second connecting rod 63 are always on a straight line. There will be no misalignment of the cylinders that would cause the laser receiver 4 to receive the signal from the laser emitter 3 but have a different signal. Figure 2 The diagram illustrates a situation where the GIS flanges are misaligned. The tails of the laser emitter 3 and laser receiver 4 will tilt upwards on the cylinder. The elastic band 1, with its elasticity, allows for an upward offset of the tails of the laser emitter 3 and laser receiver 4. Therefore, laser receiver 4 can still receive the signal from laser emitter 3. However, because both laser emitter 3 and laser receiver 4 are pushed outwards, the distance increases, and the time it takes for laser receiver 4 to receive the laser signal emitted by laser emitter 3 becomes longer. Consequently, the data signal fed back to controller 7 is also later than that of other laser receivers 4. Controller 7 determines the timing of the data signals fed back by multiple laser receivers 4 to determine which side the two cylinders are opening towards, allowing staff to make timely adjustments. This improves the docking quality of the GIS flange 81, ensuring the project can be delivered on schedule and guaranteeing safe and stable operation in the future.

[0054] The number of laser emitters 3, laser receivers 4, and positioning frames 6 are all two or more. This makes the positioning of the GIS flange 81 of the cylinder 8 more accurate, especially when there is a certain angle of axial misalignment. It is possible that the distance between two pairs of laser emitters 3 and laser receivers 4 will remain unchanged. Therefore, three pairs are set to ensure more accurate detection and more precise GIS flange docking.

[0055] like Figure 6As shown, the controller 7 includes a data output port 71 and multiple data input ports 72; multiple laser emitters 3 are connected to the data output port 71 of the controller 7, and multiple laser receivers 4 are connected to the data input ports 72 of the controller 7 in a one-to-one correspondence; the controller 7 is also equipped with a display panel 73 and a sound alarm 74.

[0056] The controller 7 controls the laser transmitter 3 to emit laser signals to the laser receiver 4 through the data output port 71. After receiving the signal, the laser receiver 4 feeds back to the controller 7 through different data input ports 72. If no signal is received, no feedback is given. The controller 7 displays the results on the display panel 73 based on whether there is a signal feedback from different data input ports 72 and the timing of the signal feedback. If a laser receiver 4 does not receive a laser signal, there will be no feedback from the data input port 72, and the controller 7 will activate the sound alarm 74 to alert the staff.

[0057] Controller 7 is either a microcontroller or a PLC. Microcontrollers or PLCs offer better performance, more functions, and are easier to program.

[0058] like Figure 5 As shown, the head 31 of the laser emitter 3 is fitted into the screw hole 82 of the GIS flange 81 at the end of the left cylinder 801 through a rubber sealing plug 5; the head 41 of the laser receiver 4 is fitted into the screw hole 82 of the GIS flange 81 at the end of the right cylinder 802 through a rubber sealing plug 5; the rubber sealing plug 5 protects the head from friction and impact on the inner wall of the screw hole 82, reduces wear and improves utilization; the rubber sealing plug 5 is stepped and can be used for GIS flanges with different screw hole 82 diameters.

[0059] like Figure 4 As shown, the body 32 of the laser emitter 3 is connected to the movable collar 2 via clamp 21; the body 42 of the laser receiver 4 is connected to the movable collar 2 via clamp 21; clamp 21 is easy to install and remove.

[0060] like Figure 7 As shown, the elastic band 1 is provided with a buckle 11, which is a shoulder strap buckle for the backpack and is easy to remove; the buckle 11 includes a plug 12 and a slot 13; one end of the elastic band 1 is connected to the plug 12 and the other end is connected to the slot 13, and the plug 12 can be inserted into the slot 13.

[0061] like Figure 8 As shown, one end of the slide rod 65 is provided with an external thread 651, and the other end is provided with an internal thread 652; by screwing the end of one slide rod 65 with the external thread 651 into the end of another slide rod 65 with the internal thread 652, multiple slide rods 65 can be spliced ​​together, increasing the length and making it suitable for positioning GIS flanges when the two cylinders 8 are far apart.
