Description

Technical Field

[0001] The invention relates to the technical field of drainage structures, in particular to a drainage device for a transformer substation. Background Art

[0002] Drainage systems are crucial to the operation and maintenance of substations, as their stable operation is crucial to the safety of the electrical equipment within them. Traditional substations often use ordinary drainage pipes to construct drainage structures. While this conventional approach can meet general drainage needs, it has significant drawbacks. For example, in earthquake-prone areas or substations located near large vibration sources (such as heavy machinery), ordinary drainage pipes lack seismic-resistant structures at their joints, making them susceptible to damage from vibrations. Cracks or loosening at these joints can lead to poor drainage and water accumulation within the substation, threatening the normal operation of electrical equipment and causing safety incidents such as short circuits and leakages. It also increases repair costs and difficulty, impacting the stability and continuity of the substation's power supply. Summary of the Invention

[0004] The technical solution of the present invention is achieved through the following measures: a substation drainage device, including an inner pipe, an outer pipe and an auxiliary pipe, the left and right ends of the inner wall of the outer pipe are respectively fixedly installed on the outer wall of the inner pipe, and the auxiliary pipe is slidably arranged between the inner wall of the outer pipe and the outer wall of the inner pipe; the outer wall of the auxiliary pipe is provided with at least two arc grooves at intervals along the circumference, and a slide groove is provided on the opposite side of the inner wall of each arc groove, and an arc plate is slidably arranged in the slide groove, and the arc plate is connected to the inner wall of the outer pipe by a connecting assembly, and a shock-proof assembly is provided between the end of the arc plate and the inner wall of the arc groove.

[0005] The following are further optimizations and / or improvements to the above technical solutions: There are two inner tubes and two outer tubes, and the two inner tubes are fixed together at one end close to each other, and the two outer tubes are fixed together at one end close to each other, and the inner wall of the other end of the outer tube is fixed together with the outer wall of the inner tube corresponding to the inner and outer ends.

[0006] In each of the above-mentioned arc grooves, a group of shockproof components is arranged between the left end of the arc plate and the left inner wall of the arc groove, and between the right end of the arc plate and the right inner wall of the arc groove. Each group of shockproof components includes two shockproof components arranged symmetrically on the left and right.

[0007] Each of the above-mentioned shock-proof components includes a first connecting block, a first movable rod, a second movable rod and a second connecting block.

One end of the elastic sheet is fixedly installed on the inner wall of the outer tube. The other end of the elastic sheet is fixedly connected to one end of the card block, and the other end of the card block is engaged with the bayonet.

[0012] The inner wall of the bayonet is provided with rounded corners.

[0019] The following are further optimizations and / or improvements to the above-mentioned substation drainage device: Example 2: As an optimization of the above example, Figure 1 、 2 As shown, there are two inner tubes 1 and two outer tubes 2. The ends of the two inner tubes 1 that are close to each other are fixed together, and the ends of the two outer tubes 2 that are close to each other are fixed together.

[0020] The two inner tubes 1 can be fixed together at one end close to each other by threads, the two outer tubes 2 can be fixed together at one end close to each other by threads, and the inner wall of the other end of the outer tube 2 and the outer wall of the inner tube 1 corresponding to the inner and outer ends thereof can be fixed together by threads.

[0021] Threads are provided on both left and right ends of each inner tube 1 .

[0022] Example 3: As an optimization of the above example, Figure 3 As shown, in each arc groove 4, a group of shockproof components 7 are arranged between the left end of the arc plate 6 and the left inner wall of the arc groove 4, and between the right end of the arc plate 6 and the right inner wall of the arc groove 4. Each group of shockproof components 7 includes two shockproof components 7 that are symmetrically arranged on the left and right.

[0023] Example 4: As an optimization of the above example, Figure 3 、 5 As shown, each shock-proof component 7 includes a first connecting block 71, a first movable rod 72, a second movable rod 74 and a second connecting block 75. The end of the first connecting block 71 is fixedly installed on the inner wall of the arc groove 4, and the other end of the first connecting block 71 is movably connected to the first movable rod 72. The end of the second connecting block 75 is fixedly installed on the end of the arc plate 6, and the other end of the second connecting block 75 is movably connected to the second movable rod 74. The other end of the first movable rod 72 is movably connected to the other end of the second movable rod 74.

[0024] Example 5: As an optimization of the above example 4, Figure 5 As shown, the other end of the first connecting block 71 is movably connected to the first movable rod 72 through a pin, the other end of the second connecting block 75 is movably connected to the second movable rod 74 through a pin, and the other end of the first movable rod 72 and the other end of the second movable rod 74 are movably connected through a pin; a shock-absorbing spring 73 is mounted on the pin between the first connecting block 71 and the first movable rod 72, a shock-absorbing spring 73 is mounted on the pin between the second connecting block 75 and the second movable rod 74, and a shock-absorbing spring 73 is mounted on the pin between the first movable rod 72 and the second movable rod 74.

[0025] After the substation drainage device is put into use, when encountering vibration, the movable connection between the first connecting block 71 and the first movable rod 72, and the movable connection between the second movable rod 74 and the second connecting block 75, especially the buffering effect of the shock-absorbing spring 73, enables the shock-proof component 7 to have an effective shock-absorbing effect, thereby reducing the damage to the pipe body of the substation drainage device caused by vibration.

[0026] Example 6: As an optimization of the above embodiment, Figure 3 As shown, in order to provide the arc-shaped plate 6 with a buffer space in the case of vibration, the length of the arc-shaped plate 6 is smaller than the length of the sliding groove 5 .

[0027] Example 7: As an optimization of the above example, Figure 3 As shown, in order to facilitate the disassembly and assembly of the arc-shaped plate 6, the arc-shaped groove 4 is trapezoidal in shape, being wide outside and narrow inside.

[0030] In addition to the structure shown in the figure, the spring piece 10 may also be a Z-shaped spring piece or other well-known spring pieces.

[0031] Example 9: As an optimization of the above example, Figure 6 As shown, the inner wall of the bayonet 8 is provided with rounded corners.

[0032] The rounded corners of the inner wall of the bayonet 8 make it easier for the clamping block 9 to smoothly move in and out of the bayonet 8 under the action of the elastic piece 10, thereby facilitating assembly and disassembly work.

[0033] The installation of this drainage device is as follows: When the pipe body needs to be installed, first connect the two inner tubes 11 together through threads, then put an outer tube 2 on the outer wall of the inner tube 1 and connect it to the inner tube 1 through threads, then install the auxiliary tube 33 between the inner tube 1 and the outer tube 2, and finally install another outer tube 2. After the auxiliary tube 3 is put on the inner tube 1 and the outer tube 2, the elastic sheet 10 is squeezed between the outside of the auxiliary tube 3 and the inside of the outer tube 2 and deformed. In the process of rotating and tightening the ends of the two outer tubes 2 close to each other, when the block 9 is rotated to the bayonet 8, the block 9 slides into the bayonet 8, and the elastic sheet 10 is restored, completing the installation of the drainage device.

[0034] The usage scenarios of this drainage device: 1) It can be installed at the connection of two drainage pipes, that is, the end of the inner pipe 1 away from the outer pipe 2 is fixed at the connection of the two drainage pipes through a thread.
