Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] 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 in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example 1

[0028] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a small intelligent circuit breaker suitable for photovoltaics, including a main body component 100, a clamping component 200, and a clutch component 300. The three components work together to selectively remove the circuit breaker when the door is opened.

[0029] Specifically, the clamping assembly 200 includes a clamping member 201, which includes a movable plate 201a, a movable bar 201b, and a clamping block 201c. There are two movable bars 201b, both of which are slidably disposed on one side of the movable plate 201a, and the movable plate 201a is disposed on one side of the movable bar 201b. There are two clamping blocks 201c, both of which are disposed on the other end of the movable bar 201b, and the movable bar 201b is located at one end of the clamping block 201c.

[0030] The inner wall of the movable plate 201a has a movable groove, and the inner wall of the clamping block 201c has a clamping groove.

[0031] When it is necessary to remove the circuit breaker 102, the moving plate 201a is moved. The movement of the moving plate 201a causes the moving bar 201b to slide on the inner wall of the moving groove. When the moving bar 201b moves, the other end slides on the inner wall of the clamping groove of the clamping block 201c. The clamping of the circuit breaker 102 can be released by the sliding of the clamping block 201c, so that the circuit breaker 102 can be taken out.

[0032] Specifically, the clutch assembly 300 is located at the bottom of the movable plate 201a and includes a clutch component 301, comprising a first engaging block 301a, a second engaging block 301b, a fixed sleeve 301c, and a moving rod 301d. The second engaging block 301b is located on one side of the first engaging block 301a, and the first engaging block 301a is located on one side of the second engaging block 301b. The first engaging block 301a and the second engaging block 301b engage and rotate. The fixed sleeve 301c is fixed to one end of the first engaging block 301a. The moving rod 301d is sleeved on the outside of the fixed sleeve 301c, and the fixed sleeve 301c and the moving rod 301d are movably connected.

[0033] By moving the movable rod 301d, the movable rod 301d moves, causing the fixed sleeve 301c to move. The fixed sleeve 301c moves, causing the first locking block 301a to engage with the second locking block 301b. With the two locking blocks engaged, the operator can directly release the clamp on the circuit breaker 102 when opening the door 103 for easy access. If it is not necessary to release the clamp on the circuit breaker 102 while opening the door 103, then the movable rod 301d does not need to be moved.

[0034] Example 2

[0035] Reference Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0036] Specifically, a support plate 202a is provided on one side of the clamping block 201c. Two support grooves 202a-1 are opened on the inner wall of the support plate 202a. The clamping block 201c slides on the inner wall of the support groove 202a-1. Fixed shafts 202b are inserted into the inner wall of the moving bar 201b. The other end of the fixed shaft 202b is fixed to one end of the support plate 202a. The moving bar 201b is movably connected to the fixed shaft 202b.

[0037] The support plate 202a is used to support the clamping block 201c. The support plate 202a is fixed to the inner wall of the distribution box 101. The fixed shaft 202b is used to support the moving bar 201b.

[0038] By moving the clamping block 201c, the clamping block 201c will slide on the inner wall of the support groove 202a-1.

[0039] Specifically, a support block 202c is provided at the bottom of the movable plate 201a, and an extrusion shaft 202d is inserted into the inner wall of the support block 202c. An extrusion block 202e is provided at one end of the extrusion shaft 202d, and the extrusion block 202e is located on the inner wall of the movable plate 201a.

[0040] The support block 202c is used to support the extrusion shaft 202d, which is a threaded rod, and the inner wall of the support block 202c is provided with a threaded groove.

[0041] By moving the extrusion shaft 202d, the extrusion shaft 202d will move on the inner wall of the support block 202c. The movement of the extrusion shaft 202d will extrude the extrusion block 202e, which will extrude the moving plate 201a. The movement of the moving plate 201a will drive the moving strip 201b to move.

[0042] Specifically, a fixing rod 202f is provided on one side of the extrusion shaft 202d, and a first bevel gear 202g is provided on the other end of the extrusion shaft 202d. There are two first bevel gears 202g, both of which are provided on one end of the extrusion shaft 202d and the fixing rod 202f. A second bevel gear 202h is provided on one side of each first bevel gear 202g.

[0043] The fixing rod 202f is used to support the other first bevel gear 202g.

[0044] By moving the moving rod 301d, the first engaging block 301a and the second engaging block 301b are engaged, and then the first bevel gear 202g is rotated. The first bevel gear 202g meshes with the second bevel gear 202h. The rotation of the second bevel gear 202h can drive the rotation of the other side's second bevel gear 202h. When the other second bevel gear 202h rotates, it can drive the other side's first bevel gear 202g to rotate, thereby driving the extrusion shaft 202d to move.

[0045] Specifically, a connecting shaft 302a is inserted into the inner wall of the first locking block 301a. The connecting shaft 302a is located at one end of the second bevel gear 202h. A fixing sleeve 301c is sleeved on the outside of the connecting shaft 302a. A spring 302b is provided at one end of the fixing sleeve 301c. A placement block 302c is fixed at the other end of the spring 302b.

[0046] The connecting shaft 302a is used to support the second bevel gear 202h.

[0047] By moving the moving rod 301d, the moving rod 301d drives the fixed sleeve 301c to move. The fixed sleeve 301c will pull the spring 302b. Through the movement of the fixed sleeve 301c, the first locking block 301a can move and engage with the second locking block 301b.

[0048] Specifically, a fixed block 302d is provided at the bottom of the movable rod 301d, the movable rod 301d is movably connected to the fixed block 302d, and a push block 302e is provided on one side of the movable rod 301d.

[0049] The fixed block 302d is used to support the moving rod 301d. One side of the pushing block 302e is set as an inclined surface. By pressing the pushing block 302e, the inclined surface on one side of the pushing block 302e will press the moving rod 301d, thereby allowing the moving rod 301d to move.

[0050] Example 3

[0051] Reference Figures 4-5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0052] Specifically, a rotating shaft 302f is provided at one end of the second locking block 301b, a protective block 302g is provided on one side of the second locking block 301b, and a second bevel gear 202h is provided at one end of the rotating shaft 302f.

[0053] The rotating shaft 302f is used to support the second locking block 301b.

[0054] The first locking block 301a engages with the second locking block 301b, and then the door 103 is opened. Opening the door 103 drives the first bevel gear 202g to rotate. The first bevel gear 202g drives the second bevel gear 202h to rotate. The second bevel gear 202h drives the rotating shaft 302f to rotate. The rotation of the rotating shaft 302f drives the second locking block 301b to rotate. The rotation of the second locking block 301b engages with the first locking block 301a, thereby allowing the first locking block 301a to rotate.

[0055] Specifically, a chain 302i is provided on one side of the movable rod 301d, and a sprocket 302j is provided on the outer sleeve of the chain 302i. One end of the sprocket 302j is sleeved on the outside of the fixed rod 202f.

[0056] There are two sprockets, 302j.

[0057] By rotating the sprocket 302j, the sprocket 302j drives the chain 302i to rotate, the chain 302i drives the sprocket 302j at the other end to rotate, and the rotation of the sprocket 302j at the other end will drive the first bevel gear 202g to rotate.

[0058] Specifically, a placement plate 302k is provided at the bottom of the fixing rod 202f, and a protective frame 302l is provided on the outer sleeve of the second bevel gear 202h.

[0059] The placement plate 302k is used to support the fixed rod 202f, and the protective frame 302l is used to protect the second bevel gear 202h. By opening the door 103, the door 103 drives the door hinge 104 to rotate, the door hinge 104 drives the sprocket 302j to rotate, the sprocket 302j drives the chain 302i to rotate, and then the fixed rod 202f rotates, which drives the first bevel gear 202g to rotate.

[0060] Specifically, it also includes the main component 100, including a distribution box 101, a circuit breaker 102, a door 103, and a door hinge 104. The circuit breaker 102 is installed on the inner wall of the distribution box 101, and the distribution box 101 is sleeved on the outside of the circuit breaker 102. The door 103 is installed on one side of the distribution box 101, and the door hinge 104 is inserted into the inner wall of the door 103. The other end of the sprocket 302j is sleeved on the outside of the door hinge 104.

[0061] The distribution box 101 is typically designed with a sealed seal to effectively prevent rainwater, dust and other external factors from entering the box and ensure the normal operation of the internal electrical components. The circuit breaker 102 plays a crucial role in the protection and control of the circuit, ensuring the safe and stable operation of the electrical system. The door 103 serves as a barrier and protector, and the door hinge 104 is used to support the door 103. The distribution box 101 has a placement slot, and the push block 302e slides on the inner wall of the placement slot.

[0062] In use, when it is necessary to easily access the circuit breaker 102 while opening the door 103, the push block 302e is pushed. The inclined surface on one side of the push block 302e will press against the moving rod 301d. The moving rod 301d drives the fixed sleeve 301c to move. Through the movement of the fixed sleeve 301c, the first locking block 301a can move and engage with the second locking block 301b. Then the door 103 is opened, and the door 103 drives the door hinge 104 to rotate. The door hinge 104 drives the sprocket 302j to rotate. When the chain 302i rotates, the sprocket 302j drives the chain 302i to rotate. The rotation of the chain 302i drives another sprocket 302j to rotate. Then, the sprocket 302j causes the fixed rod 202f to rotate. The fixed rod 202f drives the first bevel gear 202g on one side to rotate. The rotation of the first bevel gear 202g meshes with the second bevel gear 202h and rotates. The rotation of the second bevel gear 202h drives the rotating shaft 302f. The rotation of the rotating shaft 302f drives the second engaging block 301b to rotate. When the first engaging block 301a and the second engaging block 301b are engaged, the rotation of the second engaging block 301b drives the first engaging block 301a to rotate. The rotation of the first engaging block 301a drives the connecting shaft 302a to rotate. The connecting shaft 302a drives another second bevel gear 202h to rotate. The rotation of the second bevel gear 202h meshes with another first bevel gear 202g and rotates. The first bevel gear 202g drives the extrusion shaft 202d to rotate on the inner wall of the support block 202c. The movement of the extrusion shaft 202d can move the moving plate 201a. The movement of the moving plate 201a causes the moving bar 201b to slide in the moving groove on the inner wall of the moving plate 201a. The movement of the moving bar 201b also causes it to slide in the clamping groove on the inner wall of the clamping block 201c. By moving the moving bar 201b, the clamping block 201c can be moved so that the two clamping blocks 201c can move towards each other, thereby releasing the clamping of the circuit breaker 102. Then the door 103 can be opened to facilitate the removal of the circuit breaker 102.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
