Description

Technical Field

[0001] This utility model relates to the technical field of cable sealers, specifically a skid-mounted integrated electrical control cable sealer for 35kV and above substations. Background Technology

[0002] 35kV and above skid-mounted integrated electrical control substations are modular substation products that integrate design, manufacturing, installation, commissioning and service. They are characterized by compact structure, high mobility, rapid deployment and high level of intelligence, and have significant advantages in emergency power supply, temporary power supply and power supply in remote areas.

[0003] Skid-mounted integrated electrical control substations integrate the primary and secondary equipment of traditional substations (such as transformers, switchgear, protection devices, monitoring systems, etc.) into modular enclosures, enabling equipment pre-installation, factory commissioning, and rapid on-site assembly through standardized design.

[0004] The prior art discloses a 35kV and above skid-mounted integrated electrical control substation cable sealer with announcement number CN220775008U. This sealer includes a fixed frame, with positioning rods welded to the inner walls of both the upper and lower sides near the center. Through the coordinated use of components such as an adjusting plate, fixed cylinder, pull handle, pull rod, slide rod, return spring, sliding plate, stop rod, and locking ball, the 35kV and above skid-mounted integrated electrical control substation cable sealer allows for easy pulling of the locking ball from adjacent locking holes. This releases the restrictive force on the adjusting plate, enabling it to move several adjacent fixed seats downwards to form a single unit with the adjacent bottom fixed seats. This facilitates quick and easy fixing of cables within the cavity formed by two adjacent fixed seats, completing the sealing work for cables of different specifications. The structure is simple, easy to operate, and can conveniently seal and fix cables of different specifications, improving work efficiency.

[0005] The aforementioned buffer springs all have an arc-shaped seat welded to the end of the inner cavity away from the adjacent fixed seat. The arc-shaped seat clamps the cable. The cable can cause the surface of the arc-shaped seat to slide, which can damage the surface of the arc-shaped seat and prevent the arc-shaped seat from effectively clamping the cable. To disassemble the arc-shaped seat, it is necessary to cut the arc-shaped seat and the buffer spring, which can easily damage the arc-shaped seat and require a lot of time for repair. Summary of the Invention

[0006] The purpose of this utility model is to provide a skid-mounted integrated electrical control substation cable seal for 35kV and above, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a skid-mounted integrated electrical control substation cable sealer for 35kV and above, comprising a sealing device and a supporting metal plate, wherein a metal plate one is welded to the top surface of the supporting metal plate, and a metal plate two is welded to the bottom surface of the supporting metal plate, and the supporting metal plate is installed at the left and right ends of the sealing device.

[0008] The sealing device includes a clamping assembly, with limit blocks inserted into the left and right ends of the clamping assembly. Fastening threaded rods are welded to the front and rear ends of the limit blocks. Limit blocks are movably connected to the bottom end of the limit blocks. A limit plate is welded to the outward surface of the limit blocks.

[0009] The clamping assembly includes a sealing clamping block, a threaded rod inserted into the top of the sealing clamping block, metal horizontal plates movably connected to the front and rear ends of the threaded rod, a sealing rubber plate adhered to the bottom end of the metal horizontal plates, a connecting block inserted into the bottom end of the sealing clamping block, a limiting threaded rod inserted into the front end of the connecting block, a fastening threaded rod welded inside the connecting block, and connecting blocks welded to the left and right surfaces of the sealing clamping block.

[0010] Preferably, the metal horizontal plate is movably connected to the front and rear surfaces of the sealing clamping block, and the sealing rubber plate is movably connected to the inner wall surface of the bottom end of the sealing clamping block. The metal horizontal plate drives the sealing rubber plate to move upward, allowing the metal horizontal plate to slide along the front and rear surfaces of the sealing clamping block, so that the sealing rubber plate is inserted into the inner wall surface of the bottom end of the sealing clamping block, thus positioning the sealing rubber plate.

[0011] Preferably, the limiting plug is inserted into the middle position of the connecting block, the fastening threaded rod is inserted into the front and rear ends of the connecting block, the nut rotates on the surface of the fastening threaded rod, and the fastening threaded rod locks and fixes the limiting plug and the connecting block.

[0012] Preferably, the first limiting plug is movably connected to the inward end of the second limiting plug, and the second limiting plug is inserted into the middle position of the connecting block. The first limiting plug and the connecting block determine the positions of the second limiting plug and the limiting plate, making it convenient to disassemble and replace the limiting plate and the second limiting plug.

[0013] Preferably, the fastening threaded rod is inserted into the bottom end of the sealing clamping block, and the surface of the fastening threaded rod is rotated with a nut. The nut and the fastening threaded rod lock and fix the limiting threaded rod and the sealing clamping block, which facilitates the disassembly and replacement of the connecting plug and makes the replacement of the connecting plug quick and convenient.

[0014] Preferably, the connecting block is slidably connected to the inner wall surface of the supporting metal plate, the second limiting block is slidably connected to the middle position of the supporting metal plate, and the limiting plate is slidably connected to the outer surface of the supporting metal plate. The connecting block drives the second limiting block and the limiting plate to move downward, thereby determining the position of the sealing clamping block, which facilitates the disassembly and replacement of the sealing clamping block and increases the service life of the sealing clamping block.

[0015] Preferably, the first limiting plug is slidably connected to the inner wall surface of the supporting metal plate, and the first limiting plug is slidably connected to the left and right sides of the sealing clamping block. The first limiting plug slides along the left and right sides of the sealing clamping block, allowing the first limiting plug to be inserted into the interior of the connecting block, thus determining the position of the second limiting plug, making it easier and faster to disassemble the limiting plate and the second limiting plug.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 The present invention provides the following technical solution: A skid-mounted integrated electrical control substation cable sealer for 35kV and above includes a sealing device 1 and a supporting metal plate 3. A metal plate 2 is welded to the top surface of the supporting metal plate 3, and a metal plate 4 is welded to the bottom surface of the supporting metal plate 3. The supporting metal plate 3 is installed at the left and right ends of the sealing device 1.

[0022] The sealing device 1 includes a clamping assembly 13, with limit plugs 12 inserted into the left and right ends of the clamping assembly 13. Fastening threaded rods 14 are welded to the front and rear ends of the limit plugs 12, and the bottom end of the limit plugs 12 is movably connected to the limit plugs 15.

[0023] A limiting plate 11 is welded to the outer surface of the limiting plug 2 15. The limiting plug 12 is movably connected to the inner end of the limiting plug 2 15. The limiting plug 2 15 is inserted into the middle position of the connecting block 138. The limiting plug 12 and the connecting block 138 determine the position of the limiting plug 2 15 and the limiting plate 11, which facilitates the disassembly and replacement of the limiting plate 11 and the limiting plug 2 15.

[0024] The clamping assembly 13 includes a sealing clamping block 131. A threaded rod 134 is inserted into the top of the sealing clamping block 131. Metal horizontal plates 132 are movably connected to the front and rear ends of the threaded rod 134. A sealing rubber plate 133 is adhered to the bottom end of the metal horizontal plate 132. The metal horizontal plate 132 is movably connected to the front and rear surfaces of the sealing clamping block 131. The sealing rubber plate 133 is movably connected to the inner wall surface of the bottom end of the sealing clamping block 131. The metal horizontal plate 132 drives the sealing rubber plate 133 to move upward, allowing the metal horizontal plate 132 to slide along the front and rear surfaces of the sealing clamping block 131, so that the sealing rubber plate 133 is inserted into the inner wall surface of the bottom end of the sealing clamping block 131, thus positioning the sealing rubber plate 133.

[0025] A connecting plug 136 is inserted into the bottom end of the sealing clamping block 131, and a limiting threaded rod 135 is inserted into the front end of the connecting plug 136. A fastening threaded rod 137 is welded inside the connecting plug 136. The fastening threaded rod 137 is inserted into the bottom end of the sealing clamping block 131. A rotating nut is attached to the surface of the fastening threaded rod 137. The nut and the fastening threaded rod 137 lock and fix the limiting threaded rod 135 and the sealing clamping block 131, making it easy to disassemble and replace the connecting plug 136, and making the replacement of the connecting plug 136 quick and convenient.

[0026] Connecting blocks 138 are welded to the left and right sides of the sealing clamping block 131. Limiting insert 12 is slidably connected to the inner wall surface of the supporting metal plate 3. Limiting insert 12 is also slidably connected to the left and right sides of the sealing clamping block 131. As limiting insert 12 slides along the left and right sides of the sealing clamping block 131, it inserts into the interior of the connecting block 138, thus determining the position of limiting insert 15. This facilitates faster and easier disassembly of the limiting plate 11 and limiting insert 15. The connecting block 138 is slidably connected to the inner wall surface of the supporting metal plate 3, and the limiting insert 138 is slidably connected to the supporting metal plate 3. At the middle position of the supporting metal plate 3, the limiting plate 11 is slidably connected to the outer surface of the supporting metal plate 3. The connecting block 138 drives the limiting insert 15 and the limiting plate 11 to move downward, thereby determining the position of the sealing clamping block 131, which facilitates the disassembly and replacement of the sealing clamping block 131 and increases the service life of the sealing clamping block 131. The limiting insert 12 is inserted into the middle position of the connecting block 138, and the fastening threaded rod 14 is inserted into the front and rear ends of the connecting block 138. The nut rotates on the surface of the fastening threaded rod 14, and the fastening threaded rod 14 locks and fixes the limiting insert 12 and the connecting block 138.

[0027] When in use, rotate the nut, and the nut will rotate on the surface of the limiting threaded rod 135, loosening the connection between the two connecting blocks 136, pulling the limiting threaded rod 135 upward, and disengaging the limiting threaded rod 135 from the connecting blocks 136.

[0028] Next, pull the sealing clamping block 131 forward, so that the sealing clamping block 131 drives the limiting plate 11 to slide on the surface of the supporting metal plate 3 through the connecting block 138 and the limiting plug 15, thereby facilitating the disassembly of the sealing clamping block 131.

[0029] When the sealing clamping block 131 is detached from the supporting metal plate 3, it is convenient to replace the sealing clamping block 131.

[0030] Rotate the nut, and the nut will rotate on the surface of the threaded rod 134, loosening the connection between the threaded rod 134 and the sealing clamping block 131. Pull the threaded rod 134 forward, and the threaded rod 134 will disengage from the metal horizontal plate 132 and the sealing clamping block 131, loosening the connection between the metal horizontal plate 132 and the sealing clamping block 131.

[0031] Pull the metal horizontal plate 132 downwards, and the metal horizontal plate 132 will drive the sealing rubber plate 133 downwards, so that the metal horizontal plate 132 and the sealing rubber plate 133 are separated from the sealing clamping block 131, making it easy to disassemble and replace the metal horizontal plate 132 and the sealing rubber plate 133, and making the replacement of the sealing rubber plate 133 quick and convenient.

[0032] Rotate the nut, and the nut will rotate on the surface of the fastening threaded rod 14, loosening the connection between the limiting plug 12 and the connecting block 138. Then pull the limiting plug 12 upward, so that the limiting plug 12 drives the fastening threaded rod 14 upward, so that the limiting plug 12 and the fastening threaded rod 14 are separated from the connecting block 138, making it convenient to replace the limiting plug 12 and the fastening threaded rod 14.

[0033] Limiting insert 12 and fastening threaded rod 2 14 disengage from sealing clamping block 131 and connecting block 138, pulling limit plate 11 upward. Limit plate 11 drives limiting insert 2 15 upward, allowing limiting insert 2 15 to disengage from connecting block 138. This facilitates the disassembly and replacement of limit plate 11 and limiting insert 2 15, making the maintenance of limit plate 11 and limiting insert 2 15 faster and more convenient.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
