Description

Technical Field

[0001] This invention relates to the field of power equipment technology, specifically to a sealed FTU housing and its installation method. Background Technology

[0002] Feeder Terminal Units (FTUs) are core equipment in power systems. They are mainly installed at outdoor feeder nodes (such as pole-mounted switches and ring main units). Through telemetry, telesignaling, and remote control functions, they collect data such as current, voltage, and switch status of the line in real time and communicate with the power station to realize fault detection, location, and isolation. At the same time, they support remote control of switch opening and closing operations to quickly restore power to non-faulty areas.

[0003] The antenna unit, housing, and wireless terminal disclosed in patent publication number CN114006150A include: a first substrate having opposing first and second ends; a second substrate having opposing third and fourth ends, the second substrate being angled relative to the first substrate and the third end being fixedly connected to the second end; a slot structure including a first slot, a second slot, and a third slot connected sequentially at an angle, the first and second slots being located on the first substrate, and the third slot being located on the second substrate; and a feed section, with one feed section on each side of the end of the first slot away from the second slot, the feed section being used to connect to a coaxial feed line to couple and feed the slot structure. This antenna unit allows for a smaller size and improved appearance in wireless terminal products.

[0004] The aforementioned and similar housings have drawbacks such as being inconvenient to install and transport. Existing feeder terminal unit housings are mostly one-piece structures. One-piece structures are not conducive to making better use of transport space during transportation. At the same time, they mostly use bolts and other connections during installation, which is relatively cumbersome. Furthermore, the limited number of interfaces makes it difficult to expand the interfaces according to actual use, thus hindering the improvement of the housing's scope of use and convenience. Therefore, this invention is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a sealed FTU housing and its installation method to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sealed FTU housing, comprising two mutually fitted semi-shells and a top cover mounted on the top of the semi-shells. A connecting mechanism is installed on the outer walls of both semi-shells. After the two semi-shells are fitted together, a locking ring secures them together to form a housing. A fixing component is installed on the top cover to further secure the two semi-shells. An auxiliary heat dissipation mechanism for enhancing heat dissipation of internal components is installed on the top cover. An auxiliary mounting mechanism for fixing the housing in a fixed position is installed on the connecting mechanism. The connecting mechanism includes... The device includes a semi-circular ring embedded in the outer wall of a semi-shell. The two semi-shells are joined together to form a circular ring. A sealing mechanism is installed in the semi-circular ring to improve its sealing performance. One of the semi-circular rings has a groove on its outer wall, and the other semi-circular ring has a strip block that matches the groove on its outer wall. When the two semi-circular rings are joined together, the strip block is inserted into the groove. The outer wall of the semi-circular ring has a semi-threaded groove. After the two semi-circular rings are joined together, the semi-threaded groove forms a threaded groove. The two semi-shells are locked by locking a locking ring into the threaded groove on the circular ring formed by the semi-circular rings.

[0007] Furthermore, the auxiliary heat dissipation mechanism includes a heat dissipation airbag installed on the inner wall of the top cover, a top block installed on the top cover, and heat dissipation fans connected to the heat dissipation airbag installed on both outer walls of the top block. Through holes are opened on both outer walls of the top block, and heat dissipation pipes connected to the heat dissipation airbag are installed in the through holes.

[0008] Furthermore, the auxiliary installation mechanism includes a collar fitted onto the ring, the collar being located between the half-shell and the locking ring. Limiting posts are installed on the outer wall of the collar and the half-shell side, and limiting grooves corresponding to the limiting posts are opened on the half-shell. Vertical plates are installed on the bottom outer wall of the collar, and an installation plate is provided between the two vertical plates. Slots are opened on both sides of the outer wall of the installation plate, and inserts adapted to the slots are installed on the outer wall of the vertical plates facing the installation plate. Fixing grooves are opened on both sides of the top outer wall of the installation plate, and the fixing grooves pass through the inserts. The middle part of the installation plate is semi-circular, and lifting components are embedded on the outer wall of the installation plate facing the semi-circular side. Limiting plates are installed on the piston rod of the lifting components.

[0009] Furthermore, the sealing mechanism includes sealing airbags embedded in the top and bottom of the inner wall of the semi-circular ring, and a pump that communicates with the sealing airbags is embedded in the outer wall of the semi-shell.

[0010] Furthermore, the fixing component includes a positioning groove formed at the corner of the top outer wall of the half-shell, a sealing strip installed on the top outer wall of the half-shell, a positioning post corresponding to the positioning groove installed on the bottom outer wall of the top cover, and a sealing groove corresponding to the sealing strip formed on the top outer wall of the top cover.

[0011] Furthermore, magnets are embedded in the outer wall of one of the half-shells on the side of the contact surface and in the positioning groove, and iron plates are embedded in the outer side of the other half-shell on the side of the contact surface and on the outer wall of the bottom of the positioning post.

[0012] A method for installing a sealed FTU housing, using the aforementioned sealed FTU housing, includes: fitting two half-shells together to form a housing; during housing formation, the semi-circular rings on the two half-shells fit together to form a circular ring, which is used to house an expansion interface; fitting a collar onto the outer wall of the circular ring and installing a locking ring to complete the installation of an auxiliary installation mechanism on the housing; fixing the housing position using a fixing groove on the auxiliary installation mechanism in conjunction with fixing bolts; fixing the housing position using a lifting component on the auxiliary installation mechanism in conjunction with a limiting plate; and reinforcing the two half-shells by inserting a positioning post on the top cover into the positioning groove to complete the formation of the housing.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This sealed FTU housing and its installation method utilize a connecting mechanism and locking ring to lock the two half-housing units together to form the overall housing. The entire FTU consists of two half-housing units, a top cover, and internal electronic components. The modular design of the housing facilitates production and transportation. The modular design allows each part to be relatively independent, enabling maintenance by replacing or upgrading only a specific module without disassembling the entire device, saving time and costs. The auxiliary installation mechanism secures the housing to the mounting position and provides multiple installation methods to adapt to different installation scenarios. The semi-circular ring provides an expansion port to accommodate various expansion needs. The sealing mechanism fills the opening of the ring to provide a sealing effect before and after expansion, improving the overall sealing performance of the housing.

[0014] Meanwhile, the auxiliary heat dissipation mechanism provides auxiliary heat dissipation, improving the operating efficiency of the electronic components inside the housing and extending their service life. During the use of the housing, the outside air flows naturally through the heat dissipation pipe into the heat dissipation bag, and then is discharged through another heat dissipation pipe, which passively improves the efficiency of heat exchange inside the housing. The two heat dissipation fans are used for exhaust and extraction, which actively improves the efficiency of heat exchange inside the housing. The fixed components improve the fastening effect of the two half-housings, and the design of the strip groove and strip block can play a positioning role when forming a ring.

[0015] Meanwhile, the positioning and fixing effect can be achieved by setting the limiting post and the limiting groove. The semi-circular middle of the mounting plate can be adapted to protrusions of different shapes during installation, improving installation adaptability. The positioning groove and positioning post can strengthen the connection between the two half shells through the top cover. The sealing strip and sealing groove can improve the sealing performance between the top cover and the shell. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] During the installation of outdoor feeder node equipment (such as pole-mounted switches, ring main units, etc.), a sealed FTU housing is required. The sealed FTU housing provided by this invention is specifically designed for the installation of outdoor feeder node equipment. When using this sealed FTU housing for the installation of outdoor feeder node equipment, it is necessary to supply power to the components inside the sealed FTU housing that require electricity in advance to ensure the normal progress of the installation and the normal use of the housing.

[0020] like Figures 1-5As shown, the present invention provides a technical solution: a sealed FTU housing, comprising two mutually fitted half-shells 1 and a top cover 2 mounted on the top of the half-shells 1. A connecting mechanism 4 is mounted on the outer wall of each of the two half-shells 1. After the two half-shells 1 are fitted together, a locking ring 5 locks the two half-shells 1 together to form a housing. A fixing component is mounted on the top cover 2 to reinforce the locking of the two half-shells 1. An auxiliary heat dissipation mechanism 3 for enhancing heat dissipation of internal components of the housing is mounted on the top cover 2. An auxiliary installation mechanism 6 for fixing the housing in a fixed position is mounted on the connecting mechanism 4. The connecting mechanism 4 includes a semi-circular ring 401 embedded in the outer wall of the half-shell 1. The two semi-shells 1 are joined together to form a ring. A sealing mechanism 7 for improving the sealing performance of the ring is installed in the semi-shell 401. A strip groove 402 is opened on the outer wall of one semi-shell 401, and a strip block 403 adapted to the strip groove 402 is installed on the outer wall of the other semi-shell 401. When the two semi-shells 401 are joined together, the strip block 403 is inserted into the strip groove 402. A semi-threaded groove is opened on the outer wall of the semi-shell 401. After the two semi-shells 401 are joined together, the semi-threaded groove forms a threaded groove. The two semi-shells 1 are locked by locking the locking ring 5 into the threaded groove on the ring formed by the semi-shells 401.

[0021] It is important to note that the connecting mechanism 4, in conjunction with the locking ring 5, locks the two half-shells 1 together to form the housing. The entire FTU consists of two half-shells 1, a top cover 2, and internal electronic components. The modular design of the housing facilitates production and transportation. The modular design allows each part to be relatively independent, enabling maintenance by replacing or upgrading only a specific module without disassembling the entire device, saving time and costs. The auxiliary installation mechanism 6 secures the housing to the mounting position and provides multiple installation methods to adapt to different installation scenarios. The auxiliary heat dissipation mechanism 3 provides auxiliary heat dissipation, improving the operating efficiency of the internal electronic components and extending their service life. The semi-circular ring 401 forms an expansion port to accommodate different expansion needs. The sealing mechanism 7 fills the opening of the ring to provide a sealing effect before and after expansion, improving the overall sealing performance of the housing. The fixing components enhance the fastening effect of the two half-shells 1. The design of the strip groove 402 and strip block 403 provides a positioning effect when forming the ring.

[0022] like Figure 4As shown, the auxiliary heat dissipation mechanism 3 includes a heat dissipation airbag 301 installed on the inner wall of the top cover 2, a top block 302 installed on the top cover 2, and heat dissipation fans 304 connected to the heat dissipation airbag 301 installed on both outer walls of the top block 302. Through holes 303 are opened on both outer walls of the top block 302, and heat dissipation pipes connected to the heat dissipation airbag 301 are installed in the through holes 303.

[0023] It should be noted that during the use of the casing, the efficiency of heat exchange inside the casing can be passively improved by allowing outside air to flow naturally through the heat dissipation pipe into the heat dissipation bladder 301 and then being discharged through another heat dissipation pipe. The efficiency of heat exchange inside the casing can be actively improved by using two heat dissipation fans 304 for exhaust and extraction.

[0024] like Figure 5 As shown, the auxiliary installation mechanism 6 includes a collar 601 fitted onto a circular ring. The collar 601 is located between the semi-shell 1 and the locking ring 5. Limiting posts 602 are installed on the outer wall of the collar 601 on the side that is in contact with the semi-shell 1. Limiting grooves corresponding to the limiting posts 602 are opened on the semi-shell 1. Vertical plates 603 are installed on the bottom outer wall of the collar 601. An installation plate 607 is provided between the two vertical plates 603. Slots are opened on both sides of the outer wall of the installation plate 607. Insert blocks 604 that are adapted to the slots are installed on the outer wall of the vertical plates 603 facing the installation plate 607. Fixing grooves 605 are opened on both sides of the top outer wall of the installation plate 607. The fixing grooves 605 penetrate the insert blocks 604. The middle part of the installation plate 607 is semi-circular. Lifting components are embedded on the outer wall of the installation plate 607 facing the semi-circular side. Limiting plates 606 are installed on the piston rod of the lifting components.

[0025] It should be noted that the limiting post 602, in conjunction with the limiting groove, achieves a positioning and fixing effect. The semi-circular center of the mounting plate 607 allows it to accommodate protrusions of different shapes during installation, improving installation adaptability. During installation, the housing is installed in the mounting position using the fixing groove 605 and fixing bolts. The lifting assembly is activated, moving the limiting plate 606 to clamp in the mounting position, thus installing the housing in the mounting position. The lifting assembly consists of a hydraulic cylinder and a lifting component, the specific choice depending on the actual usage. The fixing groove 605 passes through the insert 604, which is used when installing the fixing bolts, thus strengthening the connection between the vertical plate 603 and the mounting plate 607.

[0026] like Figure 2 As shown, the sealing mechanism 7 includes a sealing airbag 701 embedded in the top and bottom of the inner wall of the semi-circular ring 401, and a pump 702 that communicates with the sealing airbag 701 is embedded in the outer wall of the semi-shell 1.

[0027] It should be noted that by starting the air pump 702, the amount of air filled inside the sealing airbag 701 can be adjusted. By filling the sealing airbag 701, the sealing airbag 701 can be expanded in the ring. The expansion of the four sealing airbags 701 in the ring can seal the opening in the ring.

[0028] like Figure 2 and Figure 4 As shown, the fixing component includes a positioning groove 8 opened at the corner of the top outer wall of the half shell 1, a sealing strip 9 installed on the top outer wall of the half shell 1, a positioning post 10 corresponding to the positioning groove 8 installed on the bottom outer wall of the top cover 2, and a sealing groove 11 corresponding to the sealing strip 9 opened on the top outer wall of the top cover 2.

[0029] It should be noted that the positioning groove 8 and positioning post 10 can enhance the connection between the two half-shells 1 through the top cover 2, and the sealing strip 9 can improve the sealing performance between the top cover 2 and the shell by cooperating with the sealing groove 11.

[0030] like Figures 2-4 As shown, magnets are embedded in the outer wall of one side of the contact surface of one half-shell 1 and in the positioning groove 8, and iron sheets are embedded in the outer side of the contact surface of the other half-shell 1 and the bottom outer wall of the positioning post 10.

[0031] It should be noted that the connection effect can be provided by the magnets embedded in the half-shell 1 and the positioning groove 8 and the sheet metal embedded in the half-shell 1 and the positioning post 10. At the same time, in order to improve the sealing of the two half-shells 1, the half-shell 1 can be provided with grooves and mounting protrusions. By providing magnetic connection, the shell can be assembled without the use of bolts, etc., and the installation is quick and convenient.

[0032] A method for installing a sealed FTU housing includes: fitting two half-shells 1 together to form a housing; during the housing formation, the semi-circular rings 401 on the two half-shells 1 will fit together to form a circular ring, which is used to place an expansion interface; fitting a collar 601 onto the outer wall of the circular ring and installing a locking ring 5; installing an auxiliary installation mechanism 6 on the housing; fixing the housing position by using a fixing groove 605 on the auxiliary installation mechanism 6 in conjunction with fixing bolts; fixing the housing position by using a lifting component on the auxiliary installation mechanism 6 in conjunction with a limiting plate 606; and reinforcing the two half-shells 1 by inserting a positioning post 10 on the top cover 2 into a positioning groove 8.

[0033] Although embodiments of the 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 these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended embodiments and their equivalents.
