Description

TECHNICAL FIELD

[0001] The present application relates to the field of grating, in particular to an inner flow type grating with emergency device. BACKGROUND

[0002] The inner flow type grating refers to sewage flowing into the middle of the grating, discharging from the inside to the outside through the openings on both sides of the grating, and the impurities intercepted in the inside being lifted to the slag discharge area and being washed away from the grating by the washing system in the area. The inner flow type grating has the advantages of high separation efficiency, low power consumption, no noise and good corrosion resistance, and can work continuously and stably under unattended conditions, and has a wide application prospect in the field of grating.

[0003] Due to the way of middle water inlet and both sides water outlet of the inner flow type grating, the water flow speed is slow when the water flow passes through the grating, and the flow capacity is small. When the sewage discharge is large, the traditional inner flow type grating cannot meet the normal sewage discharge efficiency, and the sewage will overflow from the channel, which seriously pollutes the working environment and greatly affects the work efficiency. SUMMARY

[0004] The main purpose of the present application is to provide an inner flow type grating with emergency device, which aims to solve the technical problem that the traditional inner flow type grating cannot meet the normal sewage discharge efficiency when the sewage discharge is large, and the sewage will overflow from the channel.

[0005] To achieve the above purpose, the present application provides an inner flow type grating with emergency device, which comprises:

[0006] A support frame comprising a top frame and a support column, the support column being arranged in the channel, the top frame being fixed on the support column, and a gap being left between the support column and the channel wall;

[0007] A rotating motor arranged at the top of the support frame, the output end of the rotating motor extending to the inside of the support frame and being connected with the inner flow type grating, the side edge of the inner flow type grating being slidingly connected with the support column, the rotating motor driving the inner flow type grating to rotate, and the water flow flowing from the middle of the support column through the inner flow type grating and flowing out from both sides of the support column;

[0008] A flow baffle arranged on the support column and located behind the inner flow type grating, the flow baffle being used for intercepting water flow and having a height lower than that of the channel;

[0009] An emergency driving assembly comprising a driving component and a gate slidingly connected with the flow baffle, an emergency grating being arranged at the position of the flow baffle relative to the gate, and the driving component being used for driving the opening and closing of the gate.

[0010] Furthermore, the driving component includes a rotating shaft and blades. The two ends of the rotating shaft are rotatably connected to the channel. Multiple blades are arranged around the rotating shaft. A gear is provided at the end of the rotating shaft. A rack is provided on the gate corresponding to the position of the gear. An idler wheel is provided between the gear and the rack. An overflow port is opened at the top of the baffle plate. The overflow port is located above the rotating shaft. Water flowing out of the overflow port impacts the blades, causing the gear to rotate and driving the idler wheel to lift the rack.

[0011] Furthermore, the bottom of the gate is flush with the bottom of the emergency grille, and the gate rises to a height greater than the height between the flow outlet and the emergency grille.

[0012] Furthermore, when the top of the gate is flush with the top of the flow port, the lowest point of the blade is lower than the lowest point of the gate.

[0013] Furthermore, it also includes a cleaning assembly, which comprises an outer cleaning component and an inner cleaning component. The outer cleaning component is mounted on a support column and located outside the inner inlet grille, and includes multiple nozzles. The nozzles are connected to an external water pump for cleaning the outer surface of the inner inlet grille. The inner cleaning component is mounted on the support column and located inside the inner inlet grille. The inner cleaning component includes a rolling brush and a first drive motor. The rolling brush is used to clean the inner surface of the inner inlet grille, and the first drive motor is used to drive the rolling brush to rotate.

[0014] Furthermore, it also includes a pretreatment component, which is arranged in front of the inner inlet grid along the water flow direction. The pretreatment component includes a rotating roller with multiple rake teeth. A collection trough is provided above the rotating roller, and a scraper is provided at the front end of the collection trough. The scraper has scraping teeth at intervals corresponding to the rake teeth. The scraping teeth are used to scrape off impurities on the rake teeth. The two ends of the rotating roller are rotatably arranged on the channel. The pretreatment component also includes a second drive motor that drives the rotating roller to rotate.

[0015] Furthermore, a drainage channel is provided below the cleaning assembly, and a partition plate is provided in the middle of the drainage channel. The drainage channel is used to guide impurities to the outside.

[0016] The beneficial effects of this invention are as follows: This device sets up a baffle plate behind the internal inlet screen, and the baffle plate is equipped with a driving component and a gate. When the water flow is small, the sewage normally passes through the internal inlet screen and is discharged from both sides. When the water flow is large, the driving component drives the gate to open, so that the water can be discharged from the emergency screen. This increases the flow capacity of the internal inlet screen and effectively improves the emergency sewage discharge capacity of the internal inlet screen, preventing water from overflowing from the channel.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Furthermore, if the embodiments of the present invention involve descriptions such as "first" or "second", such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0027] SeeFigures 1 to 7 .

[0028] This invention includes:

[0029] The support frame 1 includes a top frame 11 and a support column 12. The support column 12 is disposed in the channel, the top frame 11 is fixed on the support column 12, and a gap is left between the support column 12 and the channel wall.

[0030] A rotating motor 2 is installed on the top of the support frame 1. The output end of the rotating motor 2 extends into the interior of the support frame 1 and is connected to an inner inlet grille 21. The side of the inner inlet grille 21 is slidably connected to the support column 12. The rotating motor 2 drives the inner inlet grille 21 to rotate. Water flows in from the middle of the support column, passes through the inner inlet grille 21, and flows out from both sides of the support column 12.

[0031] A baffle plate 3 is installed on the support column 12 and located behind the inner inlet grille 21 to intercept water flow. The height of the baffle plate 3 is lower than the height of the channel.

[0032] The emergency drive assembly 4 includes a drive component 41 and a gate 42 slidably connected to a baffle plate 3. An emergency grille 31 is provided on the baffle plate 3 at a position relative to the gate 42. The drive component 41 is used to drive the opening and closing of the gate 42.

[0033] This design, by installing a baffle plate 3 behind the inner inlet grille 21, with a drive component 41 and a gate 42 on the baffle plate 3, allows sewage to pass normally through the inner inlet grille 21 and be discharged from both sides during periods of low water flow. When the water flow is high, the drive component 41 drives the gate 42 to open, allowing water to be discharged through the emergency grille 31. This increases the flow capacity of the inner inlet grille and effectively improves its emergency sewage discharge capability, preventing water from overflowing from the channel. Preferably, the emergency grille 31 can be detachably installed on the baffle plate 3 for easy subsequent cleaning.

[0034] In one embodiment, the driving component 41 includes a rotating shaft 411 and blades 412. The two ends of the rotating shaft 411 are rotatably connected to the channel. Multiple blades 412 are arranged around the rotating shaft 411. A gear 413 is provided at the end of the rotating shaft 411. A rack 421 is provided at the position of the gate 42 corresponding to the gear 413. An idler wheel 414 is provided between the gear 413 and the rack 421. An overflow port 32 is opened at the top of the baffle plate 3. The overflow port 32 is located above the rotating shaft 411. Water flowing out through the overflow port 32 impacts the blades 412, causing the gear 413 to rotate and driving the idler wheel 414 to lift the rack 421.

[0035] With this design, when the water flow is large, the water level rises until it overflows the outlet 32. The water flows out of the outlet 32 ​​and strikes the blades 412, driving the blades 412 to rotate. This, in turn, drives the rotating shaft 411 to rotate, which in turn drives the rack 421 to rise through the idler wheel 414, causing the gate 42 to rise and exposing the emergency screen 31. Water then flows out of the emergency screen 31, accelerating the flow rate. As the water flows out, the water level drops below the outlet 32. At this point, the gate 42 resets under its own weight, closing the emergency screen 31. This device converts the kinetic and potential energy of the water flow into the kinetic energy that drives the blades 412 to rotate, thereby causing the gate 42 to open and close. Compared with existing technologies that use motor drives, this device has a longer service life, lower economic costs, and a simpler structure. Moreover, it can automatically complete the emergency drainage function without human intervention, making it highly practical.

[0036] In one embodiment, the bottom of the gate 42 is flush with the bottom of the emergency grille 31, and the height to which the gate 42 rises is greater than the height between the outlet 32 ​​and the emergency grille 31. This design ensures that as much water as possible flows out of the emergency grille 31, so that when the gate 42 rises to the outlet 32, it blocks the outlet 32, allowing more water to flow out of the emergency grille 31.

[0037] In one embodiment, when the top of the gate 42 is flush with the top of the outlet 32, the lowest point of the blade 412 is lower than the lowest point of the gate 42. This design allows the water flowing from the emergency grille 31 to impact the blade 412 when the gate 42 blocks the outlet 32, further increasing its kinetic energy and driving the blade 412 to rotate. This ensures that the outlet 32 ​​remains consistently blocked, further enhancing the flow capacity of the emergency grille 31.

[0038] In one embodiment, a cleaning assembly 5 is further included. The cleaning assembly 5 includes an outer cleaning component 51 and an inner cleaning component 52. The outer cleaning component 51 is disposed on the support column 12 and located outside the inner inlet grille 21, and includes a plurality of nozzles 511. The nozzles 511 are connected to an external water pump for cleaning the outer surface of the inner inlet grille 21. The inner cleaning component 52 is disposed on the support column 12 and located inside the inner inlet grille 21. The inner cleaning component 52 includes a rolling brush 522 and a first drive motor 521. The rolling brush 522 is used to clean the inner surface of the inner inlet grille 21, and the first drive motor 521 is used to drive the rolling brush 522 to rotate.

[0039] In contrast to existing technologies, where the cleaning component 5 is typically placed on top of the inner inlet grille 21 and cleans from top to bottom, only the outer surface of the grille is cleaned. This method cannot thoroughly remove impurities from the grille, resulting in low cleaning efficiency. Furthermore, the top placement of the cleaning component 5 makes installation and maintenance inconvenient. This device, by setting an outer cleaning component 51 on the outside of the inner inlet grille 21 and an inner cleaning component 51 on the inside, with a nozzle 511 for cleaning the outer surface of the inner inlet grille 21 and a rolling brush 522 for cleaning the inner surface, effectively improves the cleaning efficiency of the inner inlet grille 21, more thoroughly removes impurities hanging on the grille holes, and increases the service life of the grille.

[0040] In one embodiment, a pretreatment component 6 is further included. The pretreatment component 6 is disposed in front of the inner inlet grid 21 along the water flow direction. The pretreatment component 6 includes a rotating roller 61 with a plurality of rake teeth 62. A collection trough 63 is disposed above the rotating roller 61. A scraper 64 is disposed at the front end of the collection trough 63. The scraper 64 has scraping teeth at intervals corresponding to the rake teeth 62. The scraping teeth are used to scrape off impurities on the rake teeth 62. The two ends of the rotating roller 61 are rotatably disposed on the channel. The pretreatment component 6 also includes a second drive motor for driving the rotating roller 61 to rotate.

[0041] With this design, the inner inlet screen 21 is usually used to intercept small impurities in the water, but its ability to clean large impurities is low. Therefore, a pretreatment component 6 is set in front of the inner inlet screen 21. Large impurities in the water flow are hooked by the rake teeth 62, and then the impurities on the rake teeth 62 are scraped off by the rotating roller 61 and fall into the collection tank 63, preventing large impurities from entering the inner inlet screen 21.

[0042] In one embodiment, a drainage channel 7 is provided below the cleaning component 5, and a partition plate 71 is provided in the middle of the drainage channel 7. The drainage channel 7 is used to guide impurities to the outside.

[0043] With this design, the drainage channel 7 can guide the impurities cleaned by the external cleaning component 51 and the internal cleaning component 51 to the external garbage bin for convenient subsequent centralized processing.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
