Description

Technical Field

[0001] This utility model belongs to the technical field of transformer supporting equipment, specifically relating to a connection mechanism between a cooling pipe and an air inlet pipe for a transformer cooling device. Background Technology

[0002] A transformer is a device that changes AC voltage based on the principle of electromagnetic induction. It consists of primary and secondary coils and an iron core, and can achieve voltage and current transformation, impedance matching, and electrical isolation. During operation, the copper losses in the windings and the iron losses in the core are converted into heat, causing the transformer temperature to rise. Currently, power distribution rooms often use cooling equipment to dissipate the heat from the internal electrical components.

[0003] For example, patent CN208014510U discloses a transformer cooling device, including a casing disposed on the outside of the transformer, an exhaust system connected to the casing, an air inlet shell at the bottom of the casing, an air inlet system connected to the air inlet shell, an air inlet pipe connected to the air inlet shell, a cooling system connected in the middle of the air inlet pipe, a cooling pipe connected to the air inlet pipe, a sealed cooling shell fixed to the outside of the cooling pipe, a water inlet pipe connected to the cooling shell, a water supply pipe connected to a water supply pipe, and an outlet pipe connected to the cooling shell. The cooling effect is achieved by using flowing water to lower the temperature of the air entering the casing.

[0004] However, there are certain drawbacks in actual use: when the air inlet pipe and the cooling pipe are connected by flanges, one person needs to hold the air inlet pipe while another person connects the two flanges with bolts. This connection method requires multiple people to operate, which is extremely inconvenient, time-consuming and easily restricted by space. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a connection mechanism between the cooling pipe and the air inlet pipe for a transformer cooling device, so as to solve the technical problems of low installation efficiency, the need for multiple people to operate the connection method, the time-consuming operation and the susceptibility to space limitations when the air inlet pipe and the cooling pipe are connected by a flange in the existing cooling device.

[0006] To solve the above-mentioned technical problems, embodiments of this utility model provide a connection mechanism between a cooling pipe and an air inlet pipe for a transformer cooling device, including a cooling pipe and an air inlet pipe. Flanges are fixedly installed at the ends of both the cooling pipe and the air inlet pipe. A connecting frame is provided between the cooling pipe and the air inlet pipe. The connecting frame has a ring-shaped structure, and a connecting assembly is provided at the top of the connecting frame. The connecting assembly includes a fixing plate, which is located at the top of the connecting frame. A sliding groove is provided on the fixing plate, and a movable connecting plate is slidably disposed within the sliding groove. A fixed connecting plate is provided on the opposite side of the movable connecting plate. Both the movable and fixed connecting plates have L-shaped cross-sections. The movable connecting plate overlaps the flange of the cooling pipe, and the fixed connecting plate is snapped onto the flange of the air inlet pipe. Both the movable and fixed connecting plates abut against the pipe bodies of the cooling pipe and the air inlet pipe.

[0007] The movable connecting plate has vertical plates at both ends of its top, and a threaded rod is provided between the two vertical plates. The threaded rod passes through the fixed plate and is threadedly connected to the fixed plate. One end of the threaded rod is fixedly connected to a rocker wheel. The rocker wheel rotates the threaded rod to drive the movable connecting plate to slide in the sliding groove.

[0008] The vertical plate is fixedly fitted with a bearing, and the threaded rod is rotatably connected to the vertical plate through the bearing.

[0009] The connecting frame has several through slots, each through slot has a thread, and the flange has through holes, with the through slots and through holes corresponding to each other.

[0010] The connecting frame is fixed with screws on both sides. The screws pass through the through holes and through the flanges of the air inlet pipe and the cooling pipe, and are threaded to the connecting frame through the through groove. A nut is screwed onto one end of the screw.

[0011] The screw has multiple paddles fixed to its surface, and the paddles are arranged in a cross shape.

[0012] The connecting frame has side grooves on both sides, which are annular grooves. A sealing ring is installed in the annular groove. The sealing ring has an annular plate structure and its thickness is slightly greater than the depth of the side groove. A double seal is formed by compression between the flanges to ensure the air tightness between the air inlet pipe and the cooling pipe.

[0013] The beneficial effects of the above-mentioned technical solution of this utility model are as follows: This utility model uses a movable connecting plate and a fixed connecting plate on a connecting frame to overlap the flanges of the cooling pipe and the air inlet pipe. Then, by rotating the lever on the screw, the screw and nut can be fixedly connected to the flange. The whole process can be operated by only one person, which is simple to operate and improves installation efficiency. Attached Figure Description

Detailed Implementation

[0015] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0016] like Figure 1 , 2 As shown, an embodiment of this utility model provides a connection mechanism between a cooling pipe and an air inlet pipe for a transformer cooling device, including a cooling pipe 1 and an air inlet pipe 2. Flanges 3 are fixedly provided at the ends of the cooling pipe 1 and the air inlet pipe 2. A connecting frame 4 is provided between the cooling pipe 1 and the air inlet pipe 2, and the connecting frame 4 has a ring structure.

[0017] like Figure 3 , Figure 4As shown, a connecting component 5 is provided on the top of the connecting frame 4. The connecting component 5 includes a fixing plate 501, which is located on the top of the connecting frame 4. A sliding groove 502 is provided on the fixing plate 501, and a movable connecting plate 504 is slidably disposed in the sliding groove 502. A fixed connecting plate 503 is provided on the opposite side of the movable connecting plate 504, and the fixed connecting plate 503 is located below the movable connecting plate 504. Both the movable connecting plate 504 and the fixed connecting plate 503 have L-shaped cross-sections. The movable connecting plate 504 overlaps the flange 3 of the cooling pipe 1, and the fixed connecting plate 503 is snapped onto the flange 3 of the air inlet pipe 2. The fixed connecting plate 503 fixes the connecting frame 4 to the flange 3 of the air inlet pipe 2. By sliding the movable connecting plate 504, the movable connecting plate 504 is controlled to align the flange 3 of the cooling pipe 1 with the flange 3 of the air inlet pipe 2. Both the movable connecting plate 504 and the fixed connecting plate 503 abut against the pipe bodies of the cooling pipe 1 and the air inlet pipe 2.

[0018] The top two ends of the movable connecting plate 504 are provided with vertical plates 505. A threaded rod 507 is provided between the two vertical plates 505 and connected by a bearing 506. The threaded rod 507 passes through the fixed plate 501 and is threadedly connected to the fixed plate 501. One end of the threaded rod 507 is fixedly connected to a rocker wheel 508. The rocker wheel 508 rotates the threaded rod 507, causing the movable connecting plate 504 to slide in the sliding groove 502.

[0019] like Figure 5 As shown, the connecting frame 4 has several through slots 401, each with a thread. The flange 3 has through holes, and the through slots 401 correspond to the through holes. Screws 402 are fixed to both sides of the connecting frame 4. The screws 402 pass through the through holes, through the flanges 3 of the air inlet pipe 2 and the cooling pipe 1, and are threaded to the connecting frame 4 through the through slots 401. A nut 403 is screwed onto one end of each screw 402. Multiple tabs 404 are fixed to the surface of the screws 402 in a cross shape.

[0020] Both sides of the connecting frame 4 are provided with side grooves 405. The side grooves 405 are annular grooves. A sealing ring 406 is provided in the annular groove. The sealing ring 406 is an annular plate structure. The thickness of the sealing ring 406 is slightly greater than the depth of the side groove 405. A double seal is formed by compression between the flanges 3 to ensure the air tightness between the air inlet pipe 2 and the cooling pipe 1.

[0021] The working principle of this utility model is as follows: During use, first, the fixed connecting plate 503 on the connecting bracket 4 is clipped onto the flange 3 of the air inlet pipe 2. Then, the movable connecting plate 504 is placed on the flange 3 of the cooling pipe 1. Rotating the rocker wheel 508 drives the threaded rod 507 to rotate on the fixed plate 501 and the vertical plate 505, thereby causing the movable connecting plate 504 to slide in the sliding groove 502. In this way, the cooling pipe 1 and the air inlet pipe 2 are brought into contact through the movement of the movable connecting plate 504. At this time, there is no need to support the air inlet pipe 2. Just pass the screw 402 through the through hole and through groove 401 and put on the nut 403. Using the lever 404, one person can complete the flange 3 connection between the cooling pipe 1 and the air inlet pipe 2. In addition, the setting of the sealing ring 406 also ensures airtightness and ensures end face sealing.

[0022] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
