Description

Technical Field

[0001] This utility model relates to the field of drainage device technology, specifically to a high-efficiency drainage device for substation foundation construction. Background Technology

[0002] A substation is a location in a power system that transforms voltage and current, receives electrical energy, and distributes it. Substations within power plants are step-up substations, whose function is to step up the voltage of the electricity generated by generators before feeding it into the high-voltage power grid. Cable trenches are underground conduits used for laying and replacing power or telecommunications cables; they also serve as the enclosure structure for the cables being laid. These trenches can have rectangular, circular, or arched structures. Whether during the initial excavation or subsequent commissioning of cable trenches, drainage systems must be installed inside to prevent water accumulation from slowing down the project and to avoid aging of the cable insulation due to water accumulation after commissioning.

[0003] Existing drainage devices have a relatively simple structure and function. They are easily clogged by impurities such as tree branches and plastic bags carried in the water. At the same time, mud in the water can also enter the drainage pipe, causing blockage. Furthermore, when there is a lot of impurities accumulated in the drainage pipe, it is not convenient for staff to clean it quickly.

[0004] Therefore, a high-efficiency drainage device for substation foundation construction is needed to solve the above problems. Utility Model Content

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up a drainage section and a filter screen, allows the water in the cable trench to be filtered first, so that impurities in the water are intercepted at the top of the filter screen. The filtered water then enters the bottom of the drainage section and settles, so that the mud in the water settles at the bottom of the drainage section. The filtered and settled water is finally discharged through the drain pipe, avoiding impurities and mud from clogging the drain pipe, ensuring that the drain pipe is always unobstructed, and improving the drainage effect of the device.

[0015] 2. This utility model, by setting up a scraper, a cover plate and a traction rope, allows the scraper to move to the right by sliding the cover plate to the left, thereby enabling the impurities and soil on the top of the filter screen and the bottom of the drainage tank to be discharged into the collection box through the first discharge tank and the second discharge tank. This achieves rapid cleaning of the top of the filter screen and the bottom of the drainage tank, ensuring the filtration effect of the filter screen and preventing soil from entering the drainage pipe and causing blockage.

[0016] 3. In this utility model, by setting a cover plate and a sealing component, during the drainage process, the cover plate is located at the far right of the top of the tank, and the sealing plate seals the first and second discharge channels to prevent water from entering the collection section, so that the collection section is in a nearly dry state, effectively preventing the generation of odors. After the drainage is completed, the cover plate is slid to the far left of the top of the tank. At this time, the first and second discharge channels will automatically adjust to the open state so that the scraper can scrape impurities and dirt into the collection section, thereby cleaning the top of the filter screen and the bottom of the drainage tank.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1-8 As shown, this utility model embodiment discloses a high-efficiency drainage device for substation foundation construction, including a trough 1. A retaining frame is provided along the edge of the trough 1, and the trough 1 is fixedly installed at the bottom of a cable trench via the retaining frame. A partition 2 is fixedly provided in the middle of the trough 1, dividing the trough 1 into a drainage section 101 and a collection section 102. It also includes:

[0029] The filter screen 3 is located in the middle of the drainage section 101. The filter screen 3 is detachable for easy installation and replacement. Water in the cable trench flows into the drainage section 101. Impurities such as leaves and plastic bags in the water are filtered and accumulate on the top of the filter screen 3. Soil settles at the bottom of the drainage section 101. The filtered and settled water is discharged through the drain pipe 8 to avoid clogging the drain pipe 8.

[0030] The partition 2 is provided with a first discharge groove 201 and a second discharge groove 202 running through it from top to bottom. The impurities accumulated on the top of the filter screen 3 are discharged into the collection section 102 through the first discharge groove 201 and the soil settled at the bottom of the drainage section 101, respectively.

[0031] The scraping assembly 4 includes a scraper 401 slidably disposed in the middle of the drainage section 101; a limiting groove 402 formed in the side wall of the drainage section 101; and a limiting slider 403 fixedly disposed on the side of the scraper 401 and slidably disposed in the limiting groove 402. Through the cooperation of the limiting groove 402 and the limiting slider 403, the scraper 401 can stably slide left and right within the drainage section 101.

[0032] It should be noted that the filter screen 3 passes through the middle of the scraper 401, and the bottom of the drainage section 101 and the top of the filter screen 3 are both in contact with the scraper 401. The bottom of the first discharge trough 201 is flush with the top of the filter screen 3, and the bottom of the second discharge trough 202 is flush with the bottom of the drainage section 101. When the scraper 401 slides in the drainage section 101, it can scrape the impurities on the top of the filter screen 3 and the soil at the bottom of the drainage section 101 into the collection section 102 through the first discharge trough 201 and the second discharge trough 202.

[0033] The sealing assembly 5 includes a sealing plate 501, which is slidably disposed inside the partition 2, and has two through slots 502 sequentially formed from top to bottom on the sealing plate 501; and a vertical slot 503, which is formed inside the partition 2, and the sealing plate 501 is slidably disposed inside the vertical slot 503. When the sealing plate 501 slides up and down in the vertical slot 503, it can control the two vertical slots 503 to simultaneously overlap / misalign with the first discharge slot 201 and the second discharge slot 202, thereby controlling the first discharge slot... The opening and closing of the first discharge trough 201 and the second discharge trough 202 are adjusted. When the two vertical troughs 503 are misaligned with the first discharge trough 201 and the second discharge trough 202, the first discharge trough 201 and the second discharge trough 202 are in a closed state, so that the water in the drainage section 101 will not enter the collection section 102; the connecting rod 504 is fixedly installed on the top of the sealing plate 501 and extends through to the top of the partition plate 2; the top block 505 is fixedly installed on the top of the connecting rod 504, and the top block 505 can... The hemispherical structure allows the abutment 507 to move downwards smoothly. The elastic element 506, sleeved around the connecting rod 504 and located between the top of the partition 2 and the bottom of the top block 505, provides an upward thrust to the top block 505. The abutment 507, fixedly mounted on the bottom of the cover plate 6, when not applying a downward thrust to the top block 505, allows the sealing plate 50 to move downwards under the upward thrust of the elastic element 506. 1. Located at the highest position within the vertical groove 503, the two vertical grooves 503 are misaligned with the first discharge groove 201 and the second discharge groove 202. Both the first discharge groove 201 and the second discharge groove 202 are in the closed state. When the top support 507 applies a downward pushing force to the top block 505 and forces the top block 505 to descend to the lowest position, the two vertical grooves 503 coincide with the first discharge groove 201 and the second discharge groove 202, and both the first discharge groove 201 and the second discharge groove 202 are in the open state.

[0034] The cover plate 6 is slidably disposed on the top of the tank 1. When the cover plate 6 is located at the rightmost position of the top of the tank 1, the upper part of the drain section 101 is in the open state and the upper part of the collection section 102 is in the closed state. Water in the cable trench enters the drain section 101 for filtration and discharge, and at this time, water will not enter the collection section 102. When the cover plate 6 is located at the leftmost position of the top of the tank 1, the upper part of the drain section 101 is in the closed state and the upper part of the collection section 102 is in the open state. The staff can remove the collection box 901 from the collection section 102 and clean it.

[0035] The traction assembly 7 includes two traction ropes 701, which are fixedly disposed between the scraper 401 and the cover plate 6. When the cover plate 6 slides, the scraper 401 can be pulled synchronously by the traction ropes 701. A wire groove 702 is formed inside the groove body 1, and the traction ropes 701 are embedded in the wire groove 702. A traction block 703 is fixedly disposed on the side of the scraper 401 and slidably disposed within the wire groove 702. One traction rope 701 is fixedly disposed on the left side of the traction block 703 and the left side of the cover plate 6. Between the two sides, another traction rope 701 is fixedly installed between the right side of the traction block 703 and the right side of the cover plate 6. When the cover plate 6 slides to the left, the scraper 401 can be pulled to the right by the traction rope 701 connected to its right side, thereby scraping the impurities on the top of the filter screen 3 and the mud at the bottom of the drainage section 101 into the collection section 102. When the cover plate 6 slides to the right, the scraper 401 can be pulled to the left by the traction rope 701 connected to its left side, thereby causing the filter screen 3 to move back to the inner left side position of the drainage section 101.

[0036] The traction component 7 can be set into two sets, and the two sets of traction components 7 are symmetrically arranged on both sides of the inside of the trough 1. By symmetrically arranging the two sets of traction components 7, the movement stability of the scraper 401 in the process of scraping away impurities and soil can be improved.

[0037] Drain pipe 8 is connected to the bottom of drainage section 101.

[0038] The collection component 9, which is capable of collecting and containing scraped soil and impurities, includes: a collection box 901, which is placed inside the collection section 102; two recovery ports 902, which are provided and are sequentially opened from top to bottom on the left side of the collection box 901, and the two recovery ports 902 are respectively aligned with the first discharge groove 201 and the second discharge groove 202; a partition 903, which is fixedly installed inside the collection box 901 and located between the two recovery ports 902, the partition 903 can separate the collected impurities and soil to achieve classified collection, and a box door is installed on the side of the collection box 901 to facilitate cleaning inside the collection box 901.

[0039] It should be noted that the bottoms of the first discharge trough 201, the second discharge trough 202, the through trough 502, and the recovery port 902 are all inclined, so that impurities and soil can slide smoothly into the collection box 901. The cover plate 6 and the top of the collection box 901 are both equipped with handles to facilitate pushing and pulling the cover plate 6 and taking out and putting in the collection box 901.

[0040] like Figure 2 As shown, during the drainage process, the cover plate 6 is located at the far right of the top of the tank 1. At this time, the top of the drainage section 101 is open, and the top support 507 does not apply downward pushing force to the top block 505. The first discharge tank 201 and the second discharge tank 202 are both closed. The water in the cable trench flows into the drainage section 101. The impurities in the water are filtered by the filter screen 3 and accumulate on the top of the filter screen 3. The mud in the water settles at the bottom of the drainage section 101. The filtered and settled water is discharged through the drain pipe 8.

[0041] like Figure 3 As shown, after the water in the cable trench is drained, there will be a lot of impurities and dirt on the top of the filter screen 3 and the bottom of the drainage section 101. At this time, it is necessary to clean the filter screen 3 and the bottom of the drainage section 101. The staff pushes the cover plate 6 to the left to the leftmost side of the top of the tank 1. At this time, the top of the collection section 102 is open. At the same time, the traction rope 701 drives the scraper 401 to move to the right. The scraper 401 scrapes away the impurities and dirt on the top of the filter screen 3 and the bottom of the drainage section 101. During this process, the top support frame 507 applies a downward pushing force to the top block 505, so that the first discharge trough 201 and the second discharge trough 202 are both open. The scraper 401 scrapes the impurities and dirt through the first discharge trough 201 and the second discharge trough 202 into the collection box 901. Then the staff lifts the collection box 901 out of the collection section 102 and cleans the impurities and dirt in the collection box 901.

[0042] By setting up a drainage section 101 and a filter screen 3, when the water in the cable trench is discharged through the drain pipe 8, it will first be filtered by the filter screen 3, so that impurities in the water are intercepted at the top of the filter screen 3. Then, the filtered water enters the bottom of the drainage section 101, and the mud in the water will settle at the bottom of the drainage section 101. Finally, the filtered and settled water is discharged through the drain pipe 8, thus preventing impurities and mud from clogging the drain pipe 8 and keeping the drain pipe 8 unobstructed, thereby improving the drainage effect of the device.

[0043] By using the scraper 401, cover plate 6 and traction rope 701 together, when the cover plate 6 is slid to the left, the cover plate 6 can drive the scraper 401 to move to the right through the traction rope 701. During the movement of the scraper 401 to the right, it will scrape away the impurities and dirt on the top of the filter screen 3 and the bottom of the drain section 101. The impurities and dirt will be collected into the collection box 901 through the first discharge trough 201 and the second discharge trough 202, so as to quickly clean the top of the filter screen 3 and the bottom of the drain section 101, thereby ensuring the filtration effect of the filter screen 3 and preventing dirt from entering the drain pipe 8.

[0044] With the cooperation of the cover plate 6 and the sealing assembly 5, during the drainage process, the cover plate 6 is located at the far right of the top of the tank 1, and the sealing plate 501 seals the first discharge channel 201 and the second discharge channel 202 to prevent water from entering the collection section 102, so that the collection section 102 is in a nearly dry state, effectively preventing the generation of odors. When the filter screen 3 and the bottom of the drainage section 101 need to be cleaned after the drainage is finished, the cover plate 6 is slid to the far left of the top of the tank 1. At this time, the first discharge channel 201 and the second discharge channel 202 will automatically adjust to the open state so that the scraper 401 can scrape impurities and dirt into the collection section 102.

[0045] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
