DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example 1 like Figures 1 to 8 As shown, an armored removable switch cabinet according to an embodiment of the present invention includes a cabinet body 100, wherein the cabinet body 100 is provided with an instrument room 101, a circuit breaker room 102, a busbar room 103, a cable room 104, and a vacuum circuit breaker 105 arranged inside the circuit breaker room 102, and includes a trolley mechanism 200 and a buffer mechanism 300 arranged in the circuit breaker room 102, and a position sensor for detecting the buffering amount of the buffer mechanism 300; the trolley mechanism 200 includes a trolley plate 201, a pulley assembly 202 arranged in the trolley plate 201, a pull rope 203 arranged on the pulley assembly 202, a handle 204 arranged on the trolley plate 201, an angle measurement sensor for detecting the offset angle of the handle 204, and a fixing assembly 205; the position sensor and the angle measurement sensor are connected to a control module through signals, and the trolley mechanism 200 detects its own state through the control module to determine when to fix its position.

[0021] Furthermore, when the vacuum circuit breaker 105 needs to be moved out of or into the circuit breaker, the movement of the trolley mechanism 200 is controlled by pushing and pulling the handle 204, thereby driving the vacuum circuit breaker 105 on the trolley mechanism 200 to move out of or into the circuit breaker. The vacuum circuit breaker 105 is installed on the vehicle plate 201. When the vacuum circuit breaker 105 needs to enter the predetermined position of the circuit breaker chamber 102, the horizontal handle 204 is first rotated vertically, and then the vehicle plate 201 is pushed inward. 1. The circuit breaker follows the vehicle plate 201 and moves continuously into the circuit breaker chamber 102. At this time, the pulley assembly 202 rotates continuously, thereby smoothly driving the vacuum circuit breaker 105 and then the circuit breaker chamber 102, saving the staff's effort and facilitating the staff's operation. At this time, the pulley assembly 202 moves to drive the pull rope 203 to move, thereby rotating the vertical handle 204, so that the vertical handle 204 gradually changes to a horizontal position, and the handle 204 is deflected in real time. The angle between the horizontal position and the horizontal position is used as the offset angle of the handle 204. As the vacuum circuit breaker 105 is continuously moved into the circuit breaker chamber, the car plate 201 will gradually approach the buffer assembly. The buffering amount of the buffer mechanism 300 is detected by the empty circuit breaker and then the circuit breaker chamber 102, and the offset angle of the handle 204 is detected by the angle measurement sensor to determine whether the trolley mechanism 200 drives the vacuum circuit breaker 105 to the predetermined position. When the trolley mechanism 200 drives the vacuum circuit breaker 105 to the predetermined position, the staff drives the fixing assembly 205 to lock the pulley assembly 202 by twisting the handle 204, thereby fixing the positions of the trolley mechanism 200 and the vacuum circuit breaker 105. The cooperation between the trolley mechanism 200 and the control module is conducive to assisting the vacuum circuit breaker 105 to enter the circuit breaker chamber 102, and is also conducive to analyzing whether the trolley mechanism 200 and the vacuum circuit breaker 105 have reached the predetermined position, providing a strong guarantee for the stable operation of the switch cabinet.

[0022] like Figures 1 to 3 As shown, the buffer mechanism 300 includes a buffer plate 301 disposed on the bottom wall of the circuit breaker chamber 102 , and a buffer spring 302 fixedly connected to the buffer plate 301 .

[0023] Furthermore, the buffer mechanism 300 helps reduce the impact generated by the trolley mechanism 200 when it moves quickly or stops, which helps protect the internal structure of the switch cabinet and the vacuum circuit breaker 105. When the trolley mechanism 200 quickly approaches or leaves its predetermined position, the buffer spring 302 absorbs and releases energy, effectively mitigating the impact.

[0024] Please pay attention to Figures 1 to 5 As shown, a sliding arc groove 201 a is provided at the front end of the vehicle plate 201 , one end of the handle 204 is slidably connected to the sliding arc groove 201 a , and the other end of the handle 204 is rotationally connected to the front end of the vehicle plate 201 .

[0025] Furthermore, when the handle 204 is rotated from horizontal to vertical or from vertical to horizontal, it rotates with the other end of the handle 204 as the center of the circle, and one end of the handle 204 slides in the sliding arc groove 201a.

[0026] Please pay attention to Figures 1 to 6 As shown, the pulley assembly 202 includes a fixed rod 202a fixedly connected to the vehicle plate 201, a rotating rod 202b rotatably connected to the fixed rod 202a, and a ratchet member 202c arranged at the end of the rotating rod 202b; a ratchet groove 201b is opened on the vehicle plate 201, and the ratchet member 202c is placed in the ratchet groove 201b and rotates.

[0027] Please pay attention to Figures 1 to 6 As shown, the vehicle plate 201 is also provided with a rope threading groove 201c, which is placed at the end of the arc sliding groove 201a. The rope threading groove 201c passes through the vehicle plate 201, and both ends of the pulling rope 203 are fixedly connected to the rotating rod 202b and one end of the handle 204 respectively.

[0028] Furthermore, the ratchet member 202c is a new type of ratchet mechanism. When the trolley mechanism 200 drives the vacuum circuit breaker 105 to move into the circuit breaker chamber 102, the outer wheel of the ratchet member 202c rotates forward. When the outer wheel rotates forward, it drives the inner wheel of the ratchet member 202c to rotate at the same time, and then drives the rotating rod 202b to rotate at the same time. At this time, the pull rope 203 is driven to follow and wrap around the rotating rod 202b. Due to the size difference between the outer wheel of the ratchet member 202c and the rotating rod 202b, when the trolley mechanism 200 moves a large distance, the pull rope 203 can only drive one end of the handle 204 to move a short distance, and when the trolley mechanism 200 moves to the preset position, the pull rope 203 just drives the handle The handle 204 is deflected from vertical to horizontal. When the trolley mechanism 200 drives the vacuum circuit breaker 105 to move to the outside of the circuit breaker, the horizontal handle 204 is first deflected to vertical. At this time, the rope 203 drives the rotating rod 202b to rotate. The rotation of the rotating rod 202b drives the inner wheel of the ratchet member 202c to reverse. At this time, the reverse rotation of the inner wheel will not drive the outer wheel to rotate. At this time, the rope 203 wrapped around the rotating rod 202b is spread out, and then the vertical handle 204 is pulled to pull the trolley mechanism 200 outward. At this time, the outer wheel of the ratchet member 202c reverses and does not drive the inner wheel to rotate. At this time, the ratchet member 202c can assist the trolley mechanism 200 to move the vacuum circuit breaker 105 out of the circuit breaker chamber 102.

[0029] Please pay attention to Figures 1 to 6 As shown, the outer wheel of the ratchet member 202c is made of metal material, and the fixing component 205 includes a fixing magnetic block 205a fixed on the traction rope 203, and the fixing magnetic block 205a can be adsorbed with the outer wheel.

[0030] Furthermore, when the trolley mechanism 200 drives the vacuum circuit breaker 105 to a predetermined position in the circuit breaker chamber 102, the pull rope 203 is wrapped around the rotating rod 202b for multiple turns. At this time, the locking magnetic block 205a follows the pull rope 203 and moves to a state where it can be adsorbed with the outer wheel of the ratchet part 202c. At this time, the position of the pull rope 203 does not move, and the locking magnetic block 205a fixes the outer wheel of the ratchet part 202c. At this time, the outer wheel of the ratchet part 202c cannot be used to drive the trolley mechanism 200 and the vacuum circuit breaker 105 to move. Therefore, the position of the trolley mechanism 200 and the vacuum circuit breaker 105 can be quickly locked by the locking magnetic block 205a.

[0031] Please pay attention to Figures 1 to 7 As shown, the fixing assembly 205 further includes a slide bar 205b fixed between the traction rope 203 and the handle 204, a side groove 205c provided on the slide bar 205b, a clamping plate 205d slidably connected to the side groove 205c, a telescopic spring 205e whose two ends are respectively fixed to the inner wall of the side groove 205c and the clamping plate 205d, and a shifting rod 205f fixedly connected to the clamping plate 205d; A shift groove 204a and a plate groove 204b are formed at one end of the handle 204, and the shift rod 205f passes through the shift groove 204a and extends out of the handle 204. A clamping groove 201d is formed on the vehicle plate 201, and the clamping groove 201d is located at the lower end of the sliding arc groove 201a and is connected to the sliding arc groove 201a.

[0032] Specifically, in order to further lock the trolley mechanism 200 and the vacuum circuit breaker 105 in a preset position, the slide bar 205b is placed in the arc slot 201a to slide. When the handle 204 is horizontal, the telescopic spring 205e is in a normal state, one end of the card plate 205d is placed in the side slot 205c, and the other end of the card plate 205d is placed in the card slot 201d. At this time, the position of the handle 204 is locked, which is beneficial to prevent the trolley mechanism 200 and the vacuum circuit breaker 105 from being displaced when the switch cabinet is shaken by external force; when the handle 204 needs to be turned vertically, the shift rod 205f is moved, and the shift rod 205f moves to drive the card plate 205d to move into the side slot 205c, and the handle 204 can be rotated at this time.

[0033] Please pay attention to Figures 1 to 8 As shown, a rolling groove 102a is provided on the bottom wall of the circuit breaker chamber 102, and an arc surface 102b is provided at the end of the rolling groove 102a.

[0034] Furthermore, when the ratchet member 202c enters the rolling groove 102a, the trolley mechanism 200 can contact the bottom wall of the circuit breaker chamber 102, thereby further enhancing the stability of the trolley mechanism 200. The arc surface 102b is provided to facilitate the rotation of the ratchet member 202c to drive the trolley mechanism 200 to move.

[0035] Example 2 like Figures 1 to 9 Please pay attention to Fig. 9 As shown, the control module includes: an angle monitoring unit, the angle monitoring unit is used to collect the offset angle of the handle 204 detected by the angle measurement sensor; a buffer detection unit, the buffer detection unit is used to collect the buffer amount of the buffer mechanism 300 detected by the position sensor; a data processing unit, the angle monitoring unit transmits the offset angle of the handle 204 detected by the angle measurement sensor to the data processing unit, the buffer detection unit transmits the buffer amount of the buffer mechanism 300 detected by the position sensor to the data processing unit, and the data processing unit performs weighted summation based on the offset angle of the handle 204 and the buffer amount of the buffer mechanism 300 to comprehensively determine whether to lock the position of the hand car mechanism 200.

[0036] The buffering amount of the buffer mechanism 300 is the difference between the initial elongation of the buffer spring 302 and the buffering elongation after buffering the opponent vehicle mechanism 200 .

[0037] Furthermore, the angle between the real-time deflection position of the handle 204 and the lateral position is taken as the offset angle of the handle 204. The larger the offset angle of the handle 204 and the buffering amount of the buffer mechanism 300, the greater the difference between the trolley mechanism 200 and the vacuum circuit breaker 105 from the preset position.

[0038] Specifically, the automatic adjustment of the control module is mainly related to two factors, one is the offset angle of the handle 204 detected by the angle measurement sensor, and the other is the buffering amount of the buffer mechanism 300 detected by the position sensor. The data processing unit performs weighted summation based on the offset angle of the handle 204 and the buffering amount of the buffer mechanism 300 to comprehensively determine whether to lock the position of the hand car mechanism 200.

[0039] In order to combine the offset angle of the handle 204 and the buffering amount of the buffer mechanism 300 by weighted summation, we have marked them as and V, and introduce two weights and to indicate their importance in the weighted sum.

[0040] The weighted sum expression can be: = × + ×V in: It is represented as the offset angle of the handle 204.

[0041] V represents the buffering amount of the buffer mechanism 300.

[0042] is the weight of the offset angle of the grip 204.

[0043] is the weight of the buffering amount of the buffer mechanism 300.

[0044] Among them, the result of weighted summation It reflects the distance between the trolley mechanism 200 and the vacuum circuit breaker 105 and the preset position. A threshold value T can be set to determine when to lock the position of the trolley mechanism 200.

[0045] Where: T is a preset threshold value, which is set according to the actual situation. When the value is lower than the threshold value T, it indicates that the position of the hand-car mechanism 200 can be locked. When it is higher than the threshold value T, it is necessary to adjust the position of the handcart mechanism 200 again, and then perform a comprehensive evaluation result S again, until the comprehensive evaluation result S is lower than the threshold value T, and then lock the position of the handcart mechanism 200.

[0046] Fixed trolley mechanism 200= ; In practical applications, the weight and The choice of should be based on the specific application scenario and requirements to ensure that they can accurately reflect the relative importance in the scenario. At the same time, the sum of these two weights should usually be equal to 1 (or 100%, if expressed as a percentage) to indicate that they together constitute the total weight of the entire weighted sum.

[0047] The angle monitoring unit transmits the offset angle of the handle 204 detected by the angle measurement sensor to the data processing unit, and the buffer detection unit transmits the buffer amount of the buffer mechanism 300 detected by the collection position sensor to the data processing unit. The data processing unit substitutes the relevant information into = × + ×V, the data processing unit is compared , T determines when to lock the position of the hand car mechanism 200. T, at this time, by rotating the handle 204, the side groove 205c of the handle 204 is aligned with the card slot 201d of the vehicle plate 201, at this time, the telescopic spring 205e is reset to drive the card plate 205d into the card slot 201d, and the position of the fixed magnetic block is fixed, so the position of the trolley mechanism 200 is locked; when >T, the position of the handcart mechanism 200 is moved again, and then the comprehensive evaluation result S is performed again until the comprehensive evaluation result S is lower than the threshold value T, and then the position of the handcart mechanism 200 is locked.

[0048] The above formulas are all dimensionless and numerical calculations. The formula is a formula for the most recent real situation obtained by collecting a large amount of data and performing software simulation. The preset parameters in the formula are set by technicians in this field according to actual conditions.
