It typically includes electrical components such as main switches, circuit breakers, contactors, and relays, which can be combined and configured as needed. Low-voltage switchgear is widely used in industrial, commercial, and residential fields and is an important component of the power system.

[0003] Low-voltage distribution cabinets are a crucial link in the power supply process for users. In daily operation, low-voltage distribution cabinets are often fully enclosed and installed in easily accessible locations like residential areas. Small animals frequently visit these cabinets, sometimes causing short circuits and damaging the equipment. When a fault or circuit breaker trips inside the cabinet, it's difficult to promptly identify or eliminate the fault for repair and location. The cabinet door must be opened for inspection and diagnosis to find issues such as burnt-out lines, circuit breaker trips, and broken switches. This hinders staff from quickly assessing the equipment's condition, increasing the difficulty and time required for fault diagnosis and power restoration. This leads to increased complaints and grievances from the public regarding power outages, raising the risk of further complaints. Summary of the Invention

[0040] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0041] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0042] Example 1

[0043] Reference Figure 1 , Figures 4-7This is the first embodiment of the present invention. This embodiment provides a low-voltage distribution cabinet smoke alarm installation mechanism, which includes a fixing unit 100, including a support base 101, a screw 102 disposed inside the support base 101, a movable block 103 disposed outside the screw 102, telescopic rods 104 symmetrically disposed on both sides of the movable block 103, a drive gear 105 disposed at the end of the telescopic rod 104, and a driven gear 106 meshing with the drive gear 105.

[0044] Preferably, the support base 101 has a rectangular structure and a hollow interior. A screw 102 is located at the bottom of the support base 101, and a bearing is mounted on the outer side of the screw 102, which is installed inside the support base 101. The screw 102 and the movable block 103 are threaded together. Rotating the screw 102 causes the movable block 103 to move along its axis. A telescopic rod 104 connects the movable block 103 to the drive gear 105. Moving the movable block 103 causes the drive gear 105 to rotate. The rotation of the drive gear 105 causes the driven gear 106 to rotate. The driven gear 106 rotates so that its end face contacts the perpendicular right-angled sides, thus fixing the support base 101 inside the cabinet. Simultaneously, the screw 102 and the movable block 103 work together to achieve stable self-locking, ensuring that the support base 101 remains fixed inside the cabinet.

[0045] Furthermore, the support base 101 includes a groove 101a formed therein and a vertical plate 101b disposed at the end of the support base 101; the screw 102 includes a hexagonal head bolt 102a disposed at its end; the screw 102 passes through the vertical plate 101b and extends to its outer side; the movable block 103 has a screw hole inside that is adapted to the screw 102; the screw 102 and the movable block 103 are threadedly connected.

[0046] Preferably, the groove 101a is provided on the surface of the support base 101, and the upright plate 101b provides support for the bearing; both ends of the screw 102 pass through the upright plate 101b and extend to its outer side; the slider 103a has a "convex" structure and slides along the inside of the groove 101a; the position of the support base 101 can be limited by the slider 103a; the movable block 103 can be moved in a straight line by the cooperation between the rotating screw 102 and the slider 103a.

[0047] Furthermore, the movable block 103 includes a slider 103a disposed at its end; the slider 103a is adapted to the slide groove 101a; the movable block 103 is slidably connected to the support base 101; the telescopic rod 104 includes a fixed rod 104a and a sleeve rod 104b sleeved on the outside of the fixed rod 104a; the fixed rod 104a and the sleeve rod 104b are slidably connected; one end of the fixed rod 104a is hinged to the movable block 103 for rotation.

[0048] Preferably, hinge seats are provided on both sides of the movable block 103; the end of the telescopic rod 104 can be hinged and rotated with the movable block 103; the fixed rod 104a and the sleeve rod 104b are slidably connected, the sleeve rod 104b has a hollow structure inside, and the fixed rod 104a can slide along the inside of the sleeve rod 104b; during the movement of the movable block 103, the end of the fixed rod 104a can be rotated along the movable block 103 at a certain angle; then the rotation of the fixed rod 104a can adjust the rotation of the sleeve rod 104b; as the movable block 103 moves and the telescopic rod 104 rotates, the fixed rod 104a can enter the inside of the sleeve rod 104b, thereby ensuring the distance extension and retraction of the telescopic rod 104.

[0049] Furthermore, the drive gear 105 is fixedly connected to the sleeve rod 104b, and the drive gear 105 is fixed in a suitable position inside the support base 101; as the telescopic rod 104 rotates, it can drive the drive gear 105 to rotate in the fixed position; and the rotation of the drive gear 105 can drive the driven gear 106 to rotate; as the driven gear 106 rotates, the two sets of driven gears 106 can rotate relative to each other; thereby realizing the change of the angle between the two sets of baffles 106a, so that the baffles 106a can better fit against the inner wall of the cabinet.

[0050] In use, the operator places a wrench on the outside of the hexagonal head bolt 102a, and then uses the tool to drive the screw 102 to rotate. The rotation of the screw 102 engages with the slider 103a and the groove 101a, thereby driving the movable block 103 to move along the axis of the screw 102. As the movable block 103 moves, it can cause the end of the fixed rod 104a to flip. As the fixed rod 104a flips, it causes the sleeve rod 104b to flip, which in turn drives the drive gear 105 to flip. As the movable block 103 gradually approaches the drive gear 105, the end of the fixed rod 104a retracts into the sleeve rod 104b. When the movable block 103 continues to move, the fixed rod 104a... 04a extends from inside the sleeve rod 104b; as the distance of the telescopic rod 104 changes, it can drive the drive gear 105 to rotate; as the drive gear 105 rotates, it can drive the driven gear 106 to rotate; as the driven gear 106 rotates, the baffle 106a set on its side wall can flip; so that the baffle 106a can contact the adjacent right-angle side inside the cabinet. As the movable block 103 moves, it can make the baffle 106a fit against the inner wall of the cabinet, thereby fixing the position between the driven gear 106 and the cabinet; at the same time, the threaded engagement between the movable block 103 and the screw 102 has a certain self-locking; thereby fixing the position of the support base 101 inside the cabinet.

[0051] In summary, by designing a system where drive gears mesh with each other, mounting holes can be avoided, allowing the base to be directly installed and fixed. This enables quick installation of the support inside the cabinet, making the operation simpler and more convenient for staff and improving their work efficiency.

[0053] Reference Figures 1 to 7 This is the second embodiment of the present invention, which differs from the first embodiment in that it further includes: In the previous embodiment, the low-voltage distribution cabinet smoke alarm installation mechanism includes a clamping unit 200, including a connecting plate 201 disposed inside the support base 101, a movable member 202 disposed at the end of the connecting plate 201, and a clamping member 203 disposed inside the movable member 202; the drive gear 105 is connected to the movable member 202 through the connecting plate 201.

[0054] Furthermore, the connecting plate 201 connects the movable part 202 to the drive gear 105; the rotation of the drive gear 105 drives the movable part 202 to move; the two sets of movable parts 202 can move relative to each other; thus, the position of the smoke alarm can be clamped and fixed; and the clamping member 203 cooperates with the movable part 202 to pre-fix the position of the smoke alarm; then, as the two sets of movable parts 202 move closer to each other, the two sets of clamping members 203 cooperate to fix the position of the smoke alarm.

[0055] Furthermore, the drive gear 105 includes a first protruding post 105a disposed at its end; the support base 101 also includes a moving groove 101c disposed inside it; the movable member 202 includes a trapezoidal block 202a, a support plate 202b disposed at the end of the trapezoidal block 202a, and a fixing plate 202c disposed above the support plate 202b; the trapezoidal block 202a includes a second protruding post 202a-1 disposed on its surface; the two ends of the telescopic rod 104 are respectively sleeved on the outside of the first protruding post 105a and the second protruding post 202a-1.

[0056] Preferably, the outer sides of the first protruding post 105a and the second protruding post 202a-1 are respectively connected to the outer sides of the end of the connecting plate 201; and the first protruding post 105a is located at an eccentric position on the end face of the drive gear 105; as the drive gear 105 rotates, it can drive the connecting plate 201 to move; as the connecting plate 201 moves, it can drive the movable part 202 to move; and the movable part 202 slides along the trajectory inside the moving groove 101c; thereby realizing that the rotation of the drive gear 105 drives the movable part 202 to move in the horizontal direction; and the fixed plate 202c is located at the end of the support plate 202b away from the trapezoidal block 202a; and the fixed plate 202c has a through hole inside.

[0057] Furthermore, the first protruding post 105a is located at the edge of the end face of the drive gear 105; the movable part 202 is adapted to the moving groove 101c; the movable part 202 is slidably connected to the support base 101; the drive gear 105 rotates to drive the movable part 202 to move in the horizontal direction; the fixed plate 202c is disposed on the surface of the support base 101.

[0058] Preferably, the rotating drive gear 105 can drive the movable part 202 to move along the trajectory inside the support base 101c; and the two sets of oppositely arranged drive gears 105 can drive the two sets of movable parts 202 to move closer or further apart; and the fixed plate 202c can move along the surface of the support base 101, and the moving groove 101c can make the movable part 202 move in the horizontal direction while also providing a certain support for the movable part 202.

[0059] Furthermore, there are two sets of clamping members 203; the two sets of clamping members 203 are symmetrically arranged; the smoke alarm body n is arranged between the two sets of clamping members 203; the end face of the clamping plate 203a is in contact with the smoke alarm body n; the two sets of moving parts 202 approach each other to compress the spring 203c located between the clamping plate 203a and the fixed plate 202c.

[0060] Preferably, the guide post 203b penetrates the fixing plate 202c and extends to its outer side, and the end of the guide post 203b is provided with a limiting plate, which can effectively prevent the clamping member 203 from falling out of the movable member 202; and the end face of the clamping plate 203a is provided with a soft pad, which can make the soft pad contact the smoke alarm and prevent damage to the sensor during clamping; and the spring 203c achieves pre-fixation of the smoke alarm through its rebound force; thus, it is easier for the staff to complete the installation operation.

[0061] In use, the operator first places the smoke detector between the two sets of clamping members 203, and then clamps the sensor between the two sets of clamping members 203, which compresses the spring 203c. The reverse force of the spring 203c pre-fixes the smoke detector, thus fixing the position of the support base 101 relative to the smoke detector. Then, following the procedure in Embodiment 1, the support base 101 is fixed at a right angle to the cabinet. As the drive gear 105 rotates, it drives the first protruding column 105a to rotate. The rotation of the first protruding column 105a drives the connecting plate 20... The end of 1 moves; the connecting plate 201 moves, causing the trapezoidal block 202a to move; the trapezoidal block 202a moves, causing the support plate 202b to move along the trajectory of the moving groove 101c; as the trapezoidal block 202a moves, it can drive the fixed plate 202c to move; the two sets of fixed plates 202c move closer to each other; as the fixed plate 202c moves, it can compress the spring 203c located between the clamping plate 203a and the spring 203c, and as the deformation of the spring 203c under compression gradually increases; the greater the rebound force of the spring 203c received by the clamping plate 203a, the more the smoke alarm can be clamped and fixed.

[0062] In summary, by cooperating with the fixing unit 100 and the clamping unit 200, while the fixing unit 100 fixes the position of the support base 101, the clamping unit 200 can further fix the position of the smoke alarm; this makes it easier for staff to operate; and the device has a simple structure and is easy to operate.

[0063] Example 3

[0064] Reference Figures 1-3This is the third embodiment of the present invention, which differs from the previous two embodiments in that it includes a power distribution cabinet 300, including a cabinet body 301 and a cabinet door 302 disposed at one end of the cabinet body 301; the cabinet door 302 is hinged to the cabinet body 301 for rotation; a support base 101 is disposed inside the cabinet body 301; and the end face of the baffle 106a is in contact with the side of the cabinet body 301 that is perpendicular to each other.

[0065] Preferably, the cabinet 301 is a hollow rectangular structure; and the cabinet 301 is equipped with a number of sensors and various components to ensure normal power transmission; and the cabinet 301 is hinged to the cabinet door 302, which makes it easier for staff to open the cabinet 301; during the installation of the support base 101, the two sets of baffles 106a are perpendicular to each other, and their end faces contact the inner wall of the cabinet 301; thus, the support base 101 can be fixed inside the cabinet 301.

[0066] Furthermore, an observation window 302a is provided on the end face of the cabinet door 302; the observation window 302a can better facilitate the observation of the situation inside the cabinet 301.

[0067] Preferably, the observation window 302a allows personnel to easily observe the situation inside the cabinet 301. In remote rural areas, if a fire occurs inside the cabinet 301, villagers can detect the situation through the observation window 302a and promptly call the power supply station, thus facilitating timely location of the fault by staff, shortening repair time, and improving work efficiency.

[0068] Preferably, the smoke sensor can transmit signals to the staff's mobile phone through the control system, which can better facilitate the staff to locate the low-voltage distribution cabinet. At the same time, the low-voltage distribution cabinet will also be equipped with a fault light and a warning bell. After receiving a smoke signal, it will emit a flashing red light and sound to warn passers-by that the distribution cabinet is faulty. This can drive pedestrians away. In addition, the bottom of the cabinet 301 is equipped with a ventilation vent, and the inside of the ventilation vent is equipped with an isolation net, which can effectively prevent small animals from entering the cabinet 301 and damaging the power while ensuring heat dissipation.
