Description

Technical Field

[0001] This invention relates to the field of power system monitoring technology, and in particular to a portable voltage detector protection box. Background Technology

[0002] Voltage stability refers to a system's ability to maintain voltage. When load admittance increases, load power also increases, and both power and voltage are controllable. Voltage collapse refers to the process of a large-scale and significant voltage drop within the system due to voltage instability. Voltage stability analysis is a theoretical analysis of this process, making it controllable. With the continuous growth of load demand and power sources moving further away from load centers, my country's power system is developing towards long-distance, large-capacity, and ultra-high-voltage transmission. At the same time, the economic pressures brought about by the introduction of the electricity market and the potential environmental protection pressures are forcing the power system to gradually approach its limit, making grid stability issues increasingly prominent. Currently, there are shortcomings in power system voltage stability detection methods. Current voltage detection methods for DC systems are cumbersome, and the detectors are inconvenient to carry. Existing voltage detectors lack corresponding protection measures when transported and packed, posing a risk of damage. The operating boxes provided with existing detectors require the detectors to be removed for use, making the operation process cumbersome.

[0003] In view of this, there is an urgent need for a portable voltage tester protection box, which can ensure that the voltage stability tester is easy to carry and avoid damage, while also simplifying the steps when using it. Summary of the Invention

The first support plate is fixedly connected to the threaded tube through a connecting block.

[0008] The linkage mechanism includes an auxiliary component disposed on the back of the first box cover and a transmission component fixedly connected to the auxiliary component.

[0009] As a further embodiment of the present invention, a set of storage boxes are symmetrically arranged on the back of the voltage detector body. The two storage boxes are respectively provided with a first limiting seat and a second limiting seat. A first limiting rod and a second limiting rod are arranged between the voltage detector body and the storage boxes. The first limiting rod is inserted into the first limiting seat and the second limiting rod is inserted into the second limiting seat.

[0010] As a further embodiment of the present invention, the auxiliary lifting assembly includes a boss, a rod, a first fixed seat, a second fixed seat, a slide rod, and a return spring. The boss is disposed on the first cover. One end of the rod is vertically disposed on the boss, and the other end of the rod is horizontally inserted into the first fixed seat. Slide rods are disposed on both ends of the first fixed seat, and both ends of the slide rods are slidably connected to the second fixed seat. A return spring is sleeved on the slide rod, and the return spring is located between the first fixed seat and the second fixed seat.

[0011] As a further embodiment of the present invention, the transmission assembly includes a side seat, a side plate, a locking rod, a first crossbar, a second crossbar, a rotating seat, a vertical rod, and a second support plate. The side seat is disposed on the inner wall of the housing, and the side plate is fixedly connected to the side seat. The locking rod is horizontally slidably connected to the side plate. One end of the locking rod is movably connected to the first crossbar. The first crossbar is diagonally connected to the second crossbar. The first and second crossbars are disposed on the rotating seat, and the rotating seat is rotatably connected to the vertical rod. The vertical rod is disposed on the side seat, and the second crossbar is movably connected to the second support plate.

[0012] As a further embodiment of the present invention, both the first guide rod and the second guide rod have a bayonet at the upper end of their rod bodies, and the outer surface of the rod body is threaded from 1 / 3 of its length.

[0013] As a further embodiment of the present invention, both the first crossbar and the second crossbar are provided with transverse grooves. The protrusion of the locking rod is movably connected in the transverse groove of the first crossbar, and the protrusion of the second mounting plate is movably connected in the transverse groove of the second crossbar.

[0036] Example 1

[0037] like Figures 1-8 As shown, a specific embodiment of the present invention is illustrated: The present invention discloses a portable voltage detector protection box, comprising: a box body 1, a voltage detector body 2, a first box cover 3 and a second box cover 4. The voltage detector body 2 is fixedly disposed on the top of the inner cavity of the box body 1. The first box cover 3 and the second box cover 4 are symmetrically connected to the top surface of the box body 1. The first box cover 3 and the second box cover 4 are used to seal the top port of the box body 1 and protect the voltage detector 2 inside the box body 1. The voltage detector body 2 is fixedly connected to the bottom of the box body 1 by a lifting mechanism 5. The first box cover 3, the second box cover 4 and the voltage detector body 2 are all connected by a linkage mechanism 6. When the top surface of the box body 1 is opened, the first box cover 3 and the second box cover 4 move the voltage detector body 2 to the outside of the box body 1 through the lifting mechanism 5 and the linkage mechanism 6.

[0038] like Figure 5 As shown, the lifting mechanism 5 includes a motor 51, a first guide rod 52, a second guide rod 53, a drive wheel 54, a driven wheel 55, a belt 56, a threaded tube 57, and a first support plate 58. The motor 51 is fixedly connected to the inner wall of the housing 1. The first guide rod 52 is fixedly connected to the output end of the motor 51. The drive wheel 54 and the driven wheel 55 are respectively sleeved on the surfaces of the first guide rod 52 and the second guide rod 53. The drive wheel 54 and the driven wheel 55 are connected by a belt 56. The threaded tube 57 is respectively sleeved on the outer surfaces of the first guide rod 52 and the second guide rod 53 and fixed to the inner wall of the housing 1. The first support plate 58 is fixedly connected to the threaded tube 57 by a connecting block.

[0039] The linkage mechanism 6 includes an auxiliary lifting component 61 disposed on the back of the first box cover 3, and a transmission component 62 fixedly connected to the auxiliary component 61.

[0040] A portable voltage detector protection box mainly consists of a box body 1, a first box cover 3 and a second box cover 4, a voltage detector body 2, a lifting mechanism 5, and a linkage mechanism 6. The box body 1 is the supporting part of the protection box of the present invention. The voltage detector body 2 is fixedly connected to the top of its inner cavity. The top of the box body 1 is provided with a first box cover 3 and a second box cover 4. These two box covers are symmetrically connected to the top surface of the box body 1 and are used to seal the top port of the box body 1, thereby protecting the voltage detector body 2. Through the coordinated work of these components, the voltage detector body 2 can automatically extend out of the box body 1 when in use and retract into the box body 1 for protection when not in use.

[0041] The lifting mechanism 5 is a key component for realizing the lifting function of the voltage detector body 2. It consists of a motor 51, a first guide rod 52, a second guide rod 53, a driving wheel 54, a driven wheel 55, a belt 56, a threaded tube 57, and a first support plate 58. The motor 51 is fixedly connected to the inner wall of the housing 1 and serves as the power source. Its output end is connected to the first guide rod 52. The driving wheel 54 and the driven wheel 55 are respectively mounted on the first guide rod 52 and the second guide rod 53, and are transmitted through the belt 56, thereby transmitting the power of the motor 51 to the second guide rod 53 and the threaded tube. 57 is sleeved on the outer surface of the first guide rod 52 and the second guide rod 53. The threaded tube 57 is fixed on the inner wall of the housing 1. The first support plate 58 is fixedly connected to the threaded tube 57 through the connecting block. The first guide rod 52 and the second guide rod 53 are threaded from 1 / 3 of the outer surface of the rod. The first guide rod 52 and the second guide rod 53 can move up and down by rotating in the threaded tube 57, thereby driving the voltage detector body 2 to complete the lifting action. The height of the voltage detector body 2 can be adjusted by the lifting mechanism 3, so that the voltage detector body 2 can be moved outside the housing 1.

[0042] The linkage mechanism 6, including auxiliary component 61 and transmission component 62, is the key to achieving synchronous opening of the box cover and lifting of the voltage detector.

[0043] See Figure 6 As shown, the auxiliary component 61 consists of a boss 611, a plug rod 612, a first fixed seat 613, a second fixed seat 614, a slide rod 615, and a return spring 616. The boss 611 is set on the first cover 3. One end of the plug rod 612 is vertically fixed on the boss 611, and the other end is horizontally inserted into the first fixed seat 613. The two ends of the slide rod 615 are respectively connected to the first fixed seat 613 and the second fixed seat 614, and a return spring 616 is sleeved on it to play a buffering role.

[0044] See Figure 7As shown, the transmission assembly 62 includes a side seat 621, a side plate 622, a locking rod 623, a first crossbar 624, a second crossbar 625, a rotating seat 626, a vertical rod 627, and a second support plate 628. The side seat 621 is fixed to the inner wall of the housing 1, and the side plate 622 is fixed to the side seat 621. The locking rod 623 is slidably connected to the side plate 622. One end of the locking rod 623 is connected to the first crossbar 624, and the first crossbar 624 is connected to the second crossbar 625 through the rotating seat 626. The second crossbar 625 is connected to the second support plate 628, and the second support plate 628 is connected to the second fixed seat 614 of the auxiliary component 61. Both crossbars are provided with transverse grooves, which cooperate with the protrusions of related components to move. When the first box cover 3 is opened, the locking rod 623 will move away from the locking slot 59 on the first guide rod 52. When the first box cover 3 is closed, the locking rod 623 will be inserted into the locking slot 59 on the first guide rod 52 to ensure that the voltage detector body 2 is limited after the box cover 1 is opened and closed.

[0045] like Figure 3 As shown, a set of storage boxes 7 symmetrically arranged on the back of the voltage detector body 2 can be used to store tools, accessories and cables. The first limiting rod 8 and the second limiting rod 9 are respectively inserted into the first limiting seat 10 and the second limiting seat 11 to ensure that the voltage detector body 2 remains stable in the box 1 and avoids shaking during transportation.

[0046] like Figure 8 As shown, the handle 12 on the first cover 3 facilitates handling, and the fixing buckle 13 is compatible with the buckle groove 14 on the second cover 4 to ensure a reliable seal when the cover is closed. Protective pads are provided inside both the first cover 3 and the second cover 4 to effectively reduce the impact on the voltage detector body 2 during transportation.

[0047] In use, the operator carries the box 1 using handle 12. After moving it to the desired location, opening the first box cover 3 and the second box cover 4 causes the protrusion 611 in the linkage mechanism 6 to push the second fixed seat 614 inward. The second fixed seat 614 then moves the protrusion on the second support plate 628, causing the first crossbar 624 and the second crossbar 625 in the transmission mechanism 62 to rotate. The second crossbar 625 pulls the locking lever 623, which moves away from the locking slot 59. Then, through the wire, electricity is supplied, and the external controller controls the motor 51 to run. The motor 51 drives the first guide rod 52 and the drive wheel 54 to rotate. The drive wheel 54 drives the driven wheel 55 to rotate through the belt 56. The drive wheel 54 and the driven wheel 55 rotate... When rotating, it also drives the first guide rod 52 and the second guide rod 53 to rotate. The first guide rod 52 and the second guide rod 53 have threads on the outer 1 / 3 of the rod body surface. They move up and down by meshing with the threads of the threaded tube 57, which also drives the voltage detector body 2 to move. When the voltage detector body 2 moves to the outside of the box 1, the storage box 7 can be pulled open to take out the cable accessories, thus facilitating personnel operation. After the operation is completed, the motor 51 is turned off, and the voltage detector body 2 moves down with the rotation of the first guide rod 52 and the second guide rod 53. The first box cover 3 and the second box cover 4 are closed, and the locking rod 623 can be inserted into the locking slot 59. The first limiting rod 10 and the second limiting rod 11 are inserted into the first limiting seat 8 and the second limiting seat 9 to fix the voltage detector body 2.

[0048] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.

[0049] Many other changes and modifications can be made without departing from the concept and scope of the present invention. It should be understood that the present invention is not limited to the specific embodiments, and the scope of the present invention is defined by the appended claims.
