A lightning protection structure for an electrical room

Abstract

This utility model discloses a lightning protection structure for an electrical room, including a mounting base with a main line plate fixedly sleeved at the bottom and a sliding groove at the top. The lightning protection structure for an electrical room provided by this utility model, by setting a connecting sleeve, allows for position adjustment of the lightning arrester after installation. Pressing the lightning arrester causes it to press the connecting sleeve through the sliding base, thus retracting the connecting sleeve into the limiting groove. Sliding the lightning arrester then moves the sliding base horizontally, achieving separation between the sliding base and the connecting sleeve. When the sliding base contacts other connecting sleeves, the lightning arrester is released, causing a lifting spring to press the lightning arrester through the connecting sleeve, thereby achieving the effect of moving and fixing the lightning arrester. This facilitates the adjustment of the lightning arrester's installation position.

Description

Technical Field

[0001] This utility model relates to the technical field of lightning protection structures for electrical rooms, specifically a lightning protection structure for electrical rooms. Background Technology

[0002] A surge arrester is an electrical device used to protect electrical equipment from high transient overvoltages and to limit the duration and amplitude of follow current. It is typically connected between the mains conductor and the ground wire and is also known as an overvoltage protector or overvoltage limiter. Surge arresters are essential components in electrical cabinets, providing protection against lightning overvoltages, switching overvoltages, and power frequency transient overvoltages. Generally, surge arresters follow the principle of shortest wiring, meaning the phase wire and ground wire are the shortest. They are often installed near the ground busbar. During installation, the surge arrester is first connected to the ground busbar or ground stake before being fixed in place. However, due to limited space in electrical cabinets, short-circuiting the surge arrester before fixing it requires sufficient operating space within the cabinet and careful planning of safety distances and wiring lengths. This places high demands on the spatial layout; otherwise, the wiring will be aesthetically unappealing.

[0003] Chinese patent CN208656213U discloses an installation structure for a surge arrester in an electrical cabinet. The structure includes an internal mounting plate and a surge arrester base. The base comprises a mounting section in the middle and grounding and fixing sections at both ends. The mounting section has several spaced-apart surge arrester fixing holes. The grounding section is bent outwards at a first predetermined angle relative to the internal mounting plate and has grounding wire fixing holes. The fixing sections are fixedly connected to the internal mounting plate and are bent at a second predetermined angle relative to the mounting section. This installation structure allows for flexible placement of the surge arrester base in any position within the electrical cabinet, without being restricted by the location of the grounding busbar. It makes efficient use of cabinet space, simplifies surge arrester fixing, facilitates wiring, and results in an aesthetically pleasing and reliable design.

[0004] The aforementioned patent has some shortcomings: when installing surge arresters in the existing technology, the installation position of the surge arrester is fixed and difficult to move, so when the position of the surge arrester needs to be adjusted after installation, the installation position needs to be re-drilled, which leads to the problem of inconvenience when adjusting the installation position of the surge arrester. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a lightning protection structure for electrical rooms to solve the problems of existing lightning protection structures for electrical rooms.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lightning protection structure for an electrical room, comprising a mounting base, a main line plate fixedly sleeved at the bottom of the mounting base, a sliding groove at the top of the mounting base, a limiting groove at the bottom of the inner cavity of the sliding groove, a connecting sleeve movably sleeved inside the limiting groove, a lifting spring movably sleeved at the bottom of the connecting sleeve, a sliding seat movably sleeved inside the sliding groove, a lightning arrester fixedly mounted on the top of the sliding seat, a flexible wire electrically connected to the top of the inner cavity of the connecting sleeve, a positioning mechanism at the top of the sliding seat, a sliding ball movably sleeved at the bottom of the sliding seat, a contact block fixedly sleeved at the bottom of the sliding seat, and a bolt threaded onto one side of the bottom of the mounting base.

[0007] Preferably, the top of the connecting sleeve is in close contact with the bottom of the sliding seat, and there are three connecting sleeves, which are evenly distributed at the bottom of the inner cavity of the sliding groove.

[0008] Preferably, the positioning mechanism includes a positioning hole, which is formed on the top of the mounting base, and a locking pin is fixedly connected to the top of the sliding base.

[0009] Preferably, the number of sliding balls is several, and the several sliding balls are symmetrically distributed at the bottom of the sliding seat with the connecting sleeve as the axis of symmetry.

[0010] Preferably, the material of the contact block is the same as that of the connecting sleeve, and the material of the contact block is copper.

[0011] This utility model provides a lightning protection structure for electrical rooms, which has the following beneficial effects:

[0012] By setting a connecting sleeve, when the surge arrester needs to be adjusted after installation, pressing the surge arrester allows it to press the connecting sleeve through the sliding seat, causing the connecting sleeve to retract into the limiting groove. At this time, sliding the surge arrester allows it to drive the sliding seat to move horizontally, thus achieving the separation effect of the sliding seat and the connecting sleeve. When the sliding seat contacts the other connecting sleeves, the surge arrester is released, causing the lifting spring to squeeze the surge arrester through the connecting sleeve, thereby achieving the moving and fixing effect of the surge arrester, thus bringing convenience to the adjustment of the surge arrester's installation position.

[0013] By setting a positioning mechanism, when the position adjustment of the surge arrester is completed and it is fixed, the sliding seat can drive the locking pin to engage inside the positioning hole, so that the positioning hole can lock and fix the sliding seat through the locking pin. This avoids the problem of sliding when the sliding seat shakes, thereby improving the stability of the sliding seat when it is fixed, and thus improving the stability of the surge arrester.

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

[0019] Please see Figure 1-3 This utility model provides a technical solution: a lightning protection structure for an electrical room, including a mounting base 1, a main line plate 2 fixedly sleeved at the bottom of the mounting base 1, a sliding groove 3 opened at the top of the mounting base 1, a limiting groove 4 opened at the bottom of the inner cavity of the sliding groove 3, a connecting sleeve 5 movably sleeved inside the limiting groove 4, a lifting spring 6 movably sleeved at the bottom of the connecting sleeve 5, a sliding seat 7 movably sleeved inside the sliding groove 3, a lightning arrester 8 fixedly installed at the top of the sliding seat 7, a flexible wire 9 electrically connected to the top of the inner cavity of the connecting sleeve 5, a positioning mechanism 10 provided at the top of the sliding seat 7, a sliding ball 11 movably sleeved at the bottom of the sliding seat 7, a contact block 12 fixedly sleeved at the bottom of the sliding seat 7, and a bolt 13 threadedly sleeved on one side of the bottom of the mounting base 1.

[0020] The top of the connecting sleeve 5 is in close contact with the bottom of the sliding seat 7, and there are three connecting sleeves 5, which are evenly distributed at the bottom of the inner cavity of the sliding groove 3. By setting the connecting sleeves 5, when the surge arrester 8 needs to be adjusted after installation, pressing the surge arrester 8 allows the surge arrester 8 to press the connecting sleeves 5 through the sliding seat 7, thereby causing the connecting sleeves 5 to retract into the interior of the limiting groove 4. At this time, sliding the surge arrester 8 allows the surge arrester 8 to drive the sliding seat 7 to move horizontally, thereby achieving the effect of separating the sliding seat 7 from the connecting sleeves 5. When the sliding seat 7 contacts the other connecting sleeves 5, it releases the surge arrester 8, causing the lifting spring 6 to squeeze the surge arrester 8 through the connecting sleeves 5, thereby achieving the effect of moving and fixing the surge arrester 8, thus bringing convenience to the installation position adjustment of the surge arrester 8.

[0021] The positioning mechanism 10 includes a positioning hole 101, which is located on the top of the mounting base 1. A locking pin 102 is fixedly connected to the top of the sliding base 7. By setting the positioning mechanism 10, when the position adjustment of the surge arrester 8 is completed and fixed, the sliding base 7 can drive the locking pin 102 to engage inside the positioning hole 101, so that the positioning hole 101 can lock and fix the sliding base 7 through the locking pin 102. This avoids the problem of sliding when the sliding base 7 shakes, thereby improving the stability of the sliding base 7 when it is fixed, that is, improving the stability of the surge arrester 8.

[0022] The number of sliding balls 11 is several, and the several sliding balls 11 are symmetrically distributed at the bottom of the sliding seat 7 with the connecting sleeve 5 as the axis of symmetry. By setting the sliding balls 11, when the sliding seat 7 moves horizontally, the sliding balls 11 can limit the sliding seat 7, thereby avoiding the problem of friction between the sliding seat 7 and the bottom of the inner cavity of the sliding groove 3 when sliding, thus improving the smoothness of the sliding seat 7.

[0023] The contact block 12 is made of the same material as the connecting sleeve 5, and the contact block 12 is made of copper. By setting the contact block 12, when the sliding seat 7 and the connecting sleeve 5 are in contact, the contact block 12 can position the sliding position of the connecting sleeve 5. When the connecting sleeve 5 contacts the contact block 12, the lifting spring 6 can drive the connecting sleeve 5 to hit the bottom of the contact block 12, thereby achieving the positioning effect of the sliding position of the connecting sleeve 5, thus bringing convenience to the positioning of the sliding position of the connecting sleeve 5.

[0024] Working principle: When the surge arrester 8 is installed and needs to be adjusted, press the surge arrester 8 so that it presses the connecting sleeve 5 through the sliding seat 7, causing the connecting sleeve 5 to retract into the limiting groove 4. Sliding the surge arrester 8 then moves the sliding seat 7 horizontally, separating the sliding seat 7 from the connecting sleeve 5. When the sliding seat 7 contacts the other connecting sleeves 5, it releases the surge arrester 8, causing the lifting spring 6 to press the surge arrester 8 through the connecting sleeve 5, thus achieving the effect of moving and fixing the surge arrester 8. This facilitates the adjustment of the surge arrester 8's installation position. When the surge arrester 8 is fixed after adjustment, the sliding seat 7 moves the locking pin 102 to engage inside the positioning hole 101, allowing the positioning hole 101 to... The sliding seat 7 is locked in place by the locking pin 102, which prevents the sliding seat 7 from sliding when it shakes, thereby improving the stability of the sliding seat 7 when it is fixed, and thus improving the stability of the surge arrester 8. When the sliding seat 7 moves horizontally, the sliding ball 11 can limit the sliding seat 7, which prevents the sliding seat 7 from rubbing against the bottom of the inner cavity of the sliding groove 3, thereby improving the smoothness of the sliding seat 7. When the sliding seat 7 contacts and connects with the connecting sleeve 5, the contact block 12 can position the sliding position of the connecting sleeve 5, so that when the connecting sleeve 5 contacts the contact block 12, the lifting spring 6 can drive the connecting sleeve 5 to hit the bottom of the contact block 12, thereby achieving the positioning effect of the sliding position of the connecting sleeve 5, thus bringing convenience to the positioning of the sliding position of the connecting sleeve 5.

[0025] 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 these 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.
