Description

Technical Field

[0001] This utility model relates to the field of maintenance devices, and more specifically, to a maintenance device for pumped storage power station units. Background Technology

[0002] Distribution boxes are widely distributed in pumped-storage power stations to rationally allocate electrical energy and facilitate circuit switching. Maintenance of these distribution boxes is a common operation in pumped-storage power stations. The boxes are mostly made of iron, which does not provide insulation. Furthermore, during maintenance, if a fault occurs at the bottom of the distribution box, it needs to be lifted or pried up. Distribution boxes are usually large, and if their location is unusual, cranes cannot be used, requiring a large number of personnel – a time-consuming and labor-intensive process. If a leakage occurs in the distribution box, the consequences could be disastrous.

[0003] A search revealed that Chinese Patent Publication No. CN210693173U discloses a "Maintenance Device for Pumped Storage Power Station Units," comprising a base, a distribution box placed on the base, and an insulating box with a door surrounding the distribution box, all mounted on the base. The base includes an insulating base plate, a support directly above the insulating base plate, a lifting assembly positioned between the insulating base plate and the support, and a lifting drive assembly for controlling the lifting assembly. The advantages of this utility model are: the maintenance device for pumped storage power station units provided by this utility model facilitates maintenance without affecting the normal use of the distribution box, operates smoothly, and saves time and effort. However, it still has the following drawbacks: (1) The existing maintenance equipment needs to be installed separately in the unit box that needs to be maintained. After one box is maintained, the maintenance equipment needs to be reinstalled in the subsequent unit box, making the maintenance process cumbersome and complicated.

[0004] (2) The existing maintenance equipment requires the operator to hold the testing device in hand to inspect the unit during installation. Holding the testing device in hand for a long time will cause fatigue to the maintenance personnel and reduce the ease of use of the maintenance equipment.

[0005] Therefore, we have made improvements to this and proposed a unit maintenance device for pumped storage power stations. Utility Model Content

[0006] The purpose of this utility model is to address the problems of existing maintenance devices requiring separate installation within the unit enclosure to be maintained, necessitating reinstallation of the device in subsequent unit enclosures after maintenance of one enclosure, which makes the maintenance process cumbersome and complex. Furthermore, the existing maintenance devices require manual hand-held inspection of the unit during installation, which causes fatigue for maintenance personnel and reduces the ease of use of the maintenance devices.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution: A maintenance device for pumped storage power station units is provided to improve the above-mentioned problems.

[0008] The present invention is as follows: The device includes a cross frame, with clamping components inside both sides of the cross frame, and an electric sliding plate slidably mounted on the lower end of the cross frame. A detection component is also mounted on the rear side of the electric sliding plate. The clamping assembly includes telescopic grooves opened inside both sides of the cross frame, and a telescopic plate is slidably disposed inside the telescopic groove; The detection component includes a mounting box fixedly installed at the lower end of the electric skateboard. A slot is provided on the rear side of the mounting box, and a plug plate is detachably inserted into the slot. A detector is fixedly installed on the outer wall of the rear end of the plug plate.

[0009] As a preferred technical solution of this utility model, the telescopic groove is provided with limiting grooves on the front and rear sides, and the telescopic plate is provided with limiting plates that cooperate with the limiting grooves on the front and rear sides.

[0010] As a preferred technical solution of this utility model, a toothed plate is fixedly installed on the side of the telescopic plate near the center of the cross frame, and a gear that cooperates with the toothed plate is rotatably installed on the inner wall of the front side of the center of the telescopic groove, and a self-locking knob is connected to the front end of the gear.

[0011] As a preferred technical solution of this utility model, a clamping plate is fixedly installed on the outer wall of the rear end of the telescopic plate away from the center of the cross frame.

[0012] As a preferred technical solution of this utility model, the insert plate has an inner groove on both sides, and an inner plate is slidably disposed inside the inner groove.

[0013] As a preferred technical solution of this utility model, a card plate is installed on the outer wall of the inner plate near the mounting box, and a slot is provided on the side wall of the slot to cooperate with the card plate.

[0014] As a preferred technical solution of this utility model, a pressure plate is fixedly installed on the outer wall of the inner plate away from the card plate, and a spring rod is provided on the side wall of the inner plate on the back side of the pressure plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: In the solution of this utility model: 1. With the addition of telescopic plates, limit plates, toothed plates, and gears, when maintenance of the pumped storage power station units is required, the condition of the units must first be checked and tested. The testing device is directly installed on the outside of the multiple units' housings in the pumped storage power station. Turning the self-locking knob drives the gear connected to it to rotate. Through the engagement of the outer wall threads, the upper and lower toothed plates are driven, causing the telescopic plates on both sides to slide in the telescopic groove. With the limit plate embedded in the limit groove, the clamping plates on both sides are driven to adjust the spacing stably, thereby firmly and efficiently clamping and installing the testing device on the front outside of the multiple units' housings for efficient testing and processing. 2. With the included insert plate, inner plate, clamping plate, pressure plate, and spring rod, when maintenance or replacement of the detection device is required, press the pressure plates on both sides to slide them into the inner groove, causing the inner plate to slide into the inner groove and the clamping plate to disengage from the slot. At the same time, squeeze the spring rod to retract it, pulling the insert plate outward to disengage it from the slot. This allows the detector to be disassembled individually for individual maintenance or replacement of different types of detection devices. After maintenance or replacement, insert the insert plate into the slot, release the pressure on the pressure plate, and the spring rod pushes the inner plate outward, causing the clamping plate to insert into the aligned slot, thus completing the reinstallation of the detector. This improves the convenience of maintenance of the inspection device. Attached Figure Description

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] like Figure 1-5 As shown, this embodiment proposes a unit maintenance device for a pumped storage power station, including a cross frame 1. Clamping components are provided inside both sides of the cross frame 1. An electric sliding plate 3 is slidably provided at the lower end of the cross frame 1. A detection component is provided on the rear side of the electric sliding plate 3. The clamping assembly includes telescopic grooves 201 opened inside both sides of the cross frame 1, and a telescopic plate 202 is slidably disposed inside the telescopic grooves 201. The detection component includes a mounting box 401 fixedly installed at the lower end of the electric slide plate 3. A slot 402 is provided on the rear side of the mounting box 401. A plug plate 403 is detachably inserted into the slot 402. A detector 404 is fixedly installed on the outer wall of the rear end of the plug plate 403.

[0023] like Figure 2 As shown, the telescopic groove 201 has a limiting groove 203 on the front and rear sides, and the telescopic plate 202 is provided with a limiting plate 204 that cooperates with the limiting groove 203. Under the limiting of the limiting plate 204 embedded in the limiting groove 203, the clamping plates 205 on both sides are driven to adjust the distance stably.

[0024] like Figure 3As shown, a toothed plate 206 is fixedly installed on the side of the telescopic plate 202 near the center of the cross frame 1. A gear 207 that cooperates with the toothed plate 206 is rotatably installed on the inner wall of the front side of the center of the telescopic groove 201. A self-locking knob 208 is connected to the front end of the gear 207. When it is necessary to inspect the unit of the energy storage power station, the condition of the unit must be checked first. The inspection device is directly installed on the outside of the housing of multiple units of the energy storage power station. Turning the self-locking knob 208 will drive the gear 207 connected to it to rotate.

[0025] like Figure 3 As shown, a clamping plate 205 is fixedly installed on the outer wall of the rear end of the telescopic plate 202 away from the center of the cross frame 1. The telescopic plates 202 on both sides slide in the telescopic groove 201. Under the limitation of the limiting plate 204 embedded in the limiting groove 203, the clamping plates 205 on both sides are driven to adjust the distance stably, thereby firmly and efficiently clamping and installing the detection device on the front side of multiple sets of chassis.

[0026] like Figure 5 As shown, the insert plate 403 has an inner groove 405 on both sides. An inner plate 406 is slidably disposed inside the inner groove 405. When the detection device needs to be maintained or replaced, the pressure plates 409 on both sides are pressed to slide into the inner groove 405, which drives the inner plate 406 to slide into the inner groove 405, so that the card plate 407 is disengaged from the card slot 408.

[0027] like Figure 5 As shown, a retaining plate 407 is installed on the outer wall of the inner plate 406 near the mounting box 401. The slot 402 has a slot 408 on its side wall that cooperates with the retaining plate 407. When the pressure on the pressure plate 409 is released, the spring rod 410 pushes the inner plate 406 outward, causing the retaining plate 407 to be inserted into the aligned slot 408, thus completing the reinstallation of the detector 404.

[0028] like Figure 5 As shown, a pressure plate 409 is fixedly installed on the outer wall of the inner plate 406 away from the card plate 407. A spring rod 410 is provided on the side wall of the inner plate 406 on the back side of the pressure plate 409. When the spring rod 410 is squeezed, it contracts and pulls the insert plate 403 outward to disengage it from the slot 402, so that the detector 404 can be disassembled separately for individual maintenance or replacement of different types of detection devices. After maintenance or replacement, the insert plate 403 is inserted into the slot 402, the pressure on the pressure plate 409 is released, the spring rod 410 pushes the inner plate 406 outward, and the card plate 407 is inserted into the aligned card slot 408.

[0029] Specifically, when using this inspection device: If maintenance of the pumped storage power station units is required, the unit condition must first be checked. The inspection device is then directly installed outside the enclosures of multiple units in the pumped storage power station. Turning the self-locking knob 208 rotates the connected gear 207, which, through the threaded engagement on the outer wall, drives the upper and lower toothed plates 206, causing the telescopic plates 202 on both sides to slide within the telescopic grooves 201. With the limiting plate 204 embedded in the limiting groove 203, the clamping plates 205 on both sides are stably adjusted, thus securely and efficiently clamping the inspection device onto the front exterior of the multiple unit enclosures for efficient inspection. When maintenance or replacement of the inspection device is required, press... The pressure plates 409 on both sides slide into the inner groove 405, causing the inner plate 406 to slide into the inner groove 405, so that the clamping plate 407 disengages from the slot 408. At the same time, the spring rod 410 is squeezed to retract, pulling the insert plate 403 outward to disengage it from the slot 402. This allows the detector 404 to be disassembled separately for individual maintenance or replacement of different types of detection devices. After maintenance or replacement, the insert plate 403 is inserted into the slot 402, the pressure on the pressure plate 409 is released, and the spring rod 410 pushes the inner plate 406 outward, causing the clamping plate 407 to insert into the aligned slot 408, thus completing the reinstallation of the detector 404 and improving the convenience of maintenance of the inspection device.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
