Description

Technical Field

[0001] The utility model relates to the technical field of electrical appliance detection, in particular to a detection device for a relay protector. Background Art

[0002] Relay protection is a key device to ensure the safe and stable operation of the system. Before leaving the factory, the relay protection device needs to use a detection device to detect its power supply status. The power supply status is usually determined by voltage and current acquisition.

[0003] Existing detection devices of this type include the "PMU voltage and current collector test platform" disclosed in Chinese patent CN209728006U. This test platform is a detection device for a relay protection device, which includes a fixed platform on which a push-pull clamp is provided. The push-pull clamp has an action output end that can output linear motion in the left and right directions. A test frame is connected to the action output end. The test frame is distributed with multiple high-current probes that can float left and right under the action of their own springs. The high-current probes are connected to a detection circuit.

[0004] For a relay protector, the relay protector includes a protector base, which is provided with a plurality of terminals for connecting corresponding wires when in use, and each large current probe corresponds to each terminal. When the relay protector needs to be tested, the relay protector is placed on a workbench so that the terminals of the relay protector face to the right. The operator adjusts the left and right, front and back, and up and down positions of the relay protector so that each terminal corresponds to the corresponding large current probe. Then, the push-pull clamp is pulled to the left, and the test stand moves to the left. The left ends of the large current probes on the test stand are pressed against the corresponding terminals of the relay protector, thereby realizing the testing of the relay protector.

[0005] The problem with the existing detection device is that since the test stand can only move left and right, the relay protector needs to be moved left and right, front and back, and up and down to ensure that the terminals of the relay protector can correspond to the probes on the test stand. However, in reality, the relay protector is relatively large in size and heavy in weight, and it is not very convenient to move the relay protector. It is time-consuming and laborious for the operator to move the relay protector, which affects the detection efficiency of the entire relay protector. Utility Model Content

[0006] The purpose of the utility model is to provide a detection device for a relay protector, so as to solve the technical problem in the prior art that the relay protector needs to be moved to achieve the position correspondence between the terminal and the probe, which is time-consuming and labor-intensive.

[0007] In order to solve the above technical problems, the technical solution of a detection device for a relay protector in the present invention is as follows:

[0008] A detection device for a relay protector includes a device bracket, which includes a placement platform for the corresponding relay protector to be placed flat so that the terminals on the relay protector face upward. The device bracket is equipped with a longitudinal movable bracket for guiding movement along the front-to-back direction, the longitudinal movable bracket is equipped with a transverse movable bracket for guiding movement along the left-right direction, and the transverse movable bracket is equipped with a vertical movable bracket for guiding movement along the up-down direction. The transverse movable bracket is provided with a driving mechanism for driving the vertical movable bracket to move up and down. The bottom of the vertical movable bracket is connected to a test frame located on the upper side of the relay protector, and the test frame is provided with a plurality of vertically arranged probes, the lower ends of which are used to contact and cooperate with corresponding terminals.

[0009] Furthermore, the probe is a spring probe that can float up and down under the action of a spring.

[0010] Furthermore, a mounting seat is provided at the bottom of the vertical movable bracket, and a dovetail guide rail is provided at the bottom of the mounting seat, the guiding direction of which is extended in the front-to-back direction. The upper end of the test frame has a guide slider that cooperates with the dovetail guide rail for guiding movement, and a tightening screw for tightening the guide slider is threadedly connected on the mounting seat.

[0011] Furthermore, the driving mechanism includes a vertically arranged driving screw, a handwheel is provided at the upper end of the driving screw, and the driving screw is threadedly connected to the vertical movable bracket.

[0012] Furthermore, the longitudinal movable bracket includes a left vertical arm and a right vertical arm. A left track is provided on the left side of the placing platform to cooperate with the guide movement of the bottom of the left vertical arm, and a right track is provided on the right side of the placing platform to cooperate with the guide movement of the bottom of the right vertical arm. The longitudinal movable bracket also includes an upper horizontal arm connected to the top of the left vertical arm and the right vertical arm. The left vertical arm, the right vertical arm and the upper horizontal arm form a "door" shaped structure, and the transverse movable bracket is guided and moved on the upper horizontal arm.

[0013] Furthermore, a left roller is provided at the bottom of the left vertical arm for contacting and rolling with the upper and lower ends of the left track; a right roller is provided at the bottom of the right vertical arm for contacting and rolling with the upper and lower ends of the right track.

[0014] Furthermore, a platform leg is provided at the bottom of the placement platform, and a lower horizontal arm is connected between the bottoms of the left vertical arm and the right vertical arm, and the lower horizontal arm is located between two adjacent platform legs in the front-to-back direction.

[0015] The beneficial effects of the present invention are as follows: when the detection device of the present invention is in use, it is only necessary to place the relay protector to be detected flat on the placement platform with the terminals of the relay protector facing upwards, and there is no need to deliberately move the heavy relay protector. The horizontal position of the probe is adjusted by the longitudinal movement of the longitudinal moving bracket and the lateral movement of the lateral moving bracket, so that the horizontal position of the probe corresponds to the position of the corresponding terminal, and then the test frame is moved downward with the vertical moving bracket, and the test bracket brings the probe into contact with the terminal to complete the detection of the relay protector. From the above analysis, it can be seen that during the entire test process, there is no need to frequently move the heavy component of the relay protector, so the labor intensity of the staff can be reduced, which helps to improve the detection efficiency.

[0022] To facilitate understanding of the present invention, the present invention is described in more detail below with reference to the accompanying drawings and specific embodiments. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the disclosure of the present invention.

[0023] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art in the field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0024] In the present invention, a detection device for a relay protector is implemented as follows: Figures 1 to 4 As shown: the device bracket includes a placement platform 5 for the corresponding relay protector to be placed flat with the terminals of the relay protector facing upwards, and four platform legs 4 are distributed at the four corners of the bottom of the placement platform 5.

[0025] A longitudinal movable bracket 1 is assembled on the placement platform 5 for guiding movement along the front-back direction, a transverse movable bracket 13 is assembled on the longitudinal movable bracket 1 for guiding movement along the left-right direction, a vertical movable bracket 11 is assembled on the transverse movable bracket 13 for guiding movement along the up-down direction, and a driving mechanism for driving the vertical movable bracket to move up and down is provided on the transverse movable bracket 13.

[0026] In this embodiment, the longitudinally movable bracket 1 includes a left vertical arm 2 and a right vertical arm 7, spaced apart and arranged side by side. An upper transverse arm 12 is connected between the upper ends of the left and right vertical arms 2 and 7, and a lower transverse arm 3 is connected between the lower ends of the left and right vertical arms 2 and 7. The lower transverse arm 3 is located below the placement platform 5 and between two adjacent platform legs 4 in the front-to-back direction. The left vertical arm, upper transverse arm, right vertical arm, and lower transverse arm form a "mouth"-shaped structure.

[0027] A left rail 22 extending in the front-to-back direction is fixed to the left side of the placement platform 5, and a right rail extending in the front-to-back direction is fixed to the right side of the placement platform. The left and right rails have rail protrusions at the upper and lower ends. The bottom of the left vertical arm is provided with a left roller 20 for contacting and rolling with the upper and lower ends of the left rail; the bottom of the right vertical arm is provided with a right roller for contacting and rolling with the upper and lower ends of the right rail. Both the left and right rollers have roller grooves for engaging with the corresponding rail protrusions. During use, a worker can manually push the longitudinal movable bracket 1 to achieve forward and backward movement of the longitudinal movable bracket.

[0028] A transverse rail 21 is fixed to the upper horizontal arm, and a transverse movable bracket 13 is guided and moved on the transverse rail. The cooperation between the transverse movable bracket 13 and the transverse rail 21 is the same as the cooperation between the left vertical arm and the left rail, which will not be described in detail here. When in use, the staff can manually push the transverse movable bracket 13 to achieve the left and right movement of the transverse movable bracket. The bottom of the vertical movable bracket is connected to a test stand 10 located on the upper side of the relay protection device. The test stand 10 is provided with a plurality of vertically arranged probes 9, the lower ends of which are used to contact and cooperate with corresponding terminals. The probes 9 are spring probes that can float up and down under the action of a spring. The spring probes belong to the existing technology and will not be described in detail here.

[0029] The bottom of the vertically movable bracket is provided with a mounting base 16. The bottom of mounting base 16 is provided with a dovetail guide rail 17 extending in the front-to-back direction. The upper end of the test frame has a guide slider 18 that cooperates with the dovetail guide rail for guidance and movement. A tightening screw 19 for tightening the guide slider is threaded onto mounting base 16. By loosening tightening screw 19, the test frame can be removed and replaced. The guide slider of the new test frame is then installed in the dovetail guide rail in the front-to-back direction. Tightening tightening screw 19 secures the guide slider and the test frame in place.

[0030] The drive mechanism includes a vertically mounted drive screw 15, with a handwheel 14 fixedly mounted at its upper end. The drive screw 15 is threadedly connected to the vertically movable bracket 11. The horizontally movable bracket is provided with two vertical guide rods extending in the vertical direction, spaced apart from each other. The vertically movable bracket slides in a guided manner with the vertical guide rods. The drive screw and the vertically movable bracket form a screw-nut mechanism. Manual rotation of the handwheel rotates the drive screw. Rotating the drive screw in one direction causes the vertically movable bracket to move upward, while rotating the drive screw in the other direction causes the vertically movable bracket to move downward.

[0031] During use, the relay protection device 6 to be tested is placed horizontally on the placement platform with the relay protection device's terminals 8 facing upward. The staff adjusts the horizontal position of the test frame, i.e., the probe, by moving the longitudinal movable bracket forward and backward and the lateral movable bracket left and right. When the horizontal position of the probe corresponds to the terminal position, the staff manually rotates the handwheel, and the test frame moves the probe downward, so that the bottom of the probe contacts the corresponding terminal, thereby completing the test of the relay protection device. In other embodiments of the present invention, the movement of the longitudinal movable bracket, the lateral movable bracket, and the vertical movable bracket can also be achieved by motor drive.
