Description

Technical Field

[0001] This utility model relates to the field of test bench technology, specifically a relay protection adjustable test bench. Background Technology

[0002] Electrical testing is conducted before electrical systems and equipment are put into use to determine whether there are any quality problems in their installation or manufacturing, and to verify whether newly installed or operating electrical equipment can be put into normal operation. This involves testing and verifying the insulation performance, electrical characteristics, and mechanical properties of each individual electrical device in the electrical system according to the relevant provisions of standards, regulations, and specifications. Among these tests, a power relay protection test bench is used to conduct electrical experiments related to electrical systems.

[0003] During the use of relay protection test benches, there are many control switches and buttons on the test bench to control the precision components inside the test bench. Since the test bench is placed outdoors, when it is not in use, a lot of dust will enter the interior of the test bench. Over time, this will affect the normal use of the test bench, shorten its service life, and fail to meet the usage requirements.

[0004] Chinese patent discloses a relay protection test bench (authorization announcement number CN218629899U). This patented technology uses a combination of connecting frame, dustproof cloth, mounting base, connecting rod and elastic component. When the test bench is not in use, the dustproof cloth can be unfolded by rotating one of the connecting frames and placing it on the support plate to protect the test bench from dust, thereby preventing a large amount of dust from entering the interior of the test bench and extending the service life of the test bench.

[0005] However, it has certain drawbacks: when the test bench is used again, the protective cloth needs to be rolled up. During this process, the dust on the surface of the protective cloth is easy to fall and drift into the surrounding environment, which not only pollutes the working environment, but may also affect the health of nearby workers.

[0011] As a further embodiment of this utility model: the collecting component includes a collecting tank, a plurality of through holes are provided at the upper end of the outer surface of the collecting tank, and the inside of the collecting tank is filled with an adsorbent liquid. A support ring is fixedly connected to the inside of the collecting tank above the adsorbent liquid, a filter plate is placed on the upper surface of the support ring, and a tank cover is fixedly connected to the upper end of the collecting tank.

[0012] As a further improvement of this utility model, the lower end of the fan is fixed to the upper surface of the main body of the relay protection test bench.

[0013] As a further embodiment of this utility model: the lower end of the support base is fixed to the upper surface of the main body of the relay protection test bench, the right end of the support rod is rotatably connected to the inner right side surface of the support base, the protective cloth moves through the front surface of the support base, and the rear ends of the two sliding frames are respectively fixed to the left and right edges of the front surface of the main body of the relay protection test bench.

[0014] As a further embodiment of this utility model: the collection tank is placed on the upper surface of the main body of the relay protection test bench, the second air duct movably passes through the filter plate and the tank cover, and the second air duct is located in the adsorption liquid.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model is equipped with a protective mechanism. The motor in the protective mechanism drives the support rod to rotate and release the protective cloth. The protective cloth protects the operation panel on the surface of the main body of the relay protection test bench, preventing dust from accumulating on the surface of the operation panel when the test bench is not used for a long time.

[0017] 2. This utility model has a collection mechanism in which a fan draws dust from the surface of the protective cloth into a collection tank. The dust is then filtered through an adsorption liquid and a filter plate before being discharged. This prevents the dust on the surface of the protective cloth from being dispersed into the surrounding environment and affecting the health of the workers during the rolling and unrolling process.

[0024] Please see Figures 1-3 In this embodiment of the present invention, an adjustable relay protection test bench includes a relay protection test bench body 1. An operation panel 2 is embedded and connected to the front surface of the relay protection test bench body 1. A protective mechanism 3 is provided on the front surface of the relay protection test bench body 1, which is located outside the operation panel 2 and on the upper surface of the relay protection test bench body 1. The protective mechanism 3 includes a support base 4. The lower end of the support base 4 is fixed to the upper surface of the relay protection test bench body 1. A motor 5 is fixed to the left side surface of the support base 4. A support rod 6 is fixed to the output end of the motor 5. The right end of the support rod 6 is rotatably connected to the inner right side surface of the support base 4. A protective cloth 7 is wrapped around the outside of the support rod 6. The protective cloth 7 moves through the front surface of the support base 4. A counterweight 8 is fixed to the lower front surface of the protective cloth 7. Sliding frames 9 are slidably connected to the left and right ends of the counterweight 8. The rear ends of the two sliding frames 9 are respectively fixed to the left and right edges of the front surface of the relay protection test bench body 1.

[0025] The operation panel 2 includes a display panel, power port, signal jack, adjustment knobs, etc., and is used for electrical experiments;

[0026] Motor 5 is connected to the forward and reverse circuit and has a brake, meaning that the motor shaft cannot rotate after power is cut off.

[0027] The protective cloth 7 has a certain thickness. After it is released, it can fit the front surface of the main body 1 of the relay protection test bench, thus preventing dust from adhering to the operation panel 2 when not in use.

[0028] The counterweight 8 has sufficient weight to allow the protective cloth 7 to be released normally, and the protective cloth 7 is taut when the counterweight 8 descends to the bottom.

[0029] exist Figure 1 , Figure 2 , Figure 4 and Figure 5 In the relay protection test bench body 1, a collection mechanism 10 is installed on the upper surface behind the protection mechanism 3. The collection mechanism 10 includes a fan 11, the lower end of which is fixed to the upper surface of the relay protection test bench body 1. A first air duct 12 is fixed to the air inlet end of the fan 11, a suction pipe 13 is fixed to the left end of the first air duct 12, and a second air duct 14 is fixed to the air outlet end of the fan 11. A collection component 15, including a collection tank 16, is installed outside the second air duct 14. The collecting tank 16 is placed on the upper surface of the main body 1 of the relay protection test bench. Multiple through holes 17 are opened at the upper end of the outer surface of the collecting tank 16, and the inside of the collecting tank 16 is filled with adsorbent liquid 18. A support ring 19 is fixedly connected to the inside of the collecting tank 16 above the adsorbent liquid 18. A filter plate 20 is placed on the upper surface of the support ring 19. A tank cover 21 is fixedly connected to the upper end of the collecting tank 16. The second air duct 14 movably passes through the filter plate 20 and the tank cover 21, and the second air duct 14 is located in the adsorbent liquid 18.

[0030] The suction tube 13 includes a tube body and a suction hole opened on the lower surface of the tube body. The suction hole is strip-shaped and its length is slightly less than the length of the suction tube 13.

[0031] The part of the protective cloth 7 near the support base 4 is bent, and the suction tube 13 is directly opposite the bent part of the protective cloth 7.

[0032] The fan 11 draws air, drawing the dust from the surface of the protective cloth 7 into the collection unit 15;

[0033] The through hole 17 is located above the filter plate 20;

[0034] The collection tank 16 and the tank cover 21 can be fixed together by a threaded connection;

[0035] The adsorption liquid 18 can be water, which is used to adsorb dust in the air. The filter plate 20 filters the adsorbed air again, and the air after secondary filtration is discharged through the through hole 17.

[0036] The air pressure generated by the fan 11 is greater than the water pressure, allowing air to be discharged normally into the clean water.

[0037] The working principle of this utility model is as follows: After using the test bench, the user can turn on the motor 5 to drive the support rod 6 to rotate and release the protective cloth 7 until the counterweight 8 descends to the bottom, thus protecting the operation panel 2 with the protective cloth 7; the next time it is used, the motor 5 is turned on to drive the support rod 6 to reverse, thereby retracting the protective cloth 7; at the same time, the fan 11 uses the suction pipe 13 to draw the dust on the surface of the protective cloth 7 into the collection tank 16, and the dusty air is filtered through the adsorption liquid 18 and the filter plate 20 and discharged through the through hole 17, thus preventing the dust on the surface of the protective cloth 7 from being scattered into the surrounding environment and affecting the health of the staff during the process of retracting the protective cloth 7.
