Background
In underground coal mine operation, water damage is one of the important hidden troubles affecting the safe production, and the water quality contains a large amount of cinder, sediment and corrosive substances, which are easy to cause the risks of blockage, pump body abrasion and component corrosion. Along with the increase of mine exploitation depth and the complexity of geological conditions, water accidents such as water bursting, water seepage and water damage such as the old water frequently happen, and higher requirements are put on the safety, reliability and intelligent level of drainage.
In the prior art, such as the submersible sewage pumps of the gram-rich SL1, SLV series, the product is used for the treatment of waste water, process water and sewage. The pump is designed for intermittent and continuous operation for submersible installations, can handle large-sized solids, and is suitable for dry matter waste water. The pump can be quickly and conveniently detached from the motor device by utilizing the unique stainless steel clamp assembly, so that the maintenance and the inspection are convenient, and special tools are not needed.
In the practical application process, the product has some defects, in particular to a single anti-blocking structure of the device, has weaker impurity treatment capacity on cinder and the like, and can cause frequent blocking and difficult maintenance to influence the drainage efficiency. In addition, the safety protection mechanism of the device is insufficient, multi-parameter sensing and linkage response are not integrated, and great potential safety hazards exist in sudden water damage or complex environments. Therefore, it is necessary to provide an intelligent water damage emergency drainage device capable of automatically adjusting the drainage rate.
Disclosure of Invention
In order to solve the problems, the invention provides the intelligent water damage emergency drainage device capable of automatically adjusting the drainage rate, a composite filtering structure of a plurality of groups of screens is adopted, and under the redundant design of the plurality of groups of screens, even if one screen cannot work normally due to sediment accumulation, the other screens can still maintain filtering, so that the risk of secondary water damage caused by equipment failure is reduced. The system has the advantages that the sediment treatment flow of interception, cleaning and discharge is formed through the integrated design of the adjusting system and each component, the manual intervention is reduced, the screen maintenance is synchronously completed in the drainage process, the equipment shutdown frequency is reduced, and the system is suitable for underground narrow areas or long-term unattended emergency drainage scenes.
In order to achieve the purpose, the intelligent water damage emergency drainage device capable of automatically adjusting the drainage rate comprises a box body and an adjusting system for controlling the operation of the device, wherein the box body is communicated with a water inlet pipe and a plurality of water outlet pipes, and a filtering component for intercepting sediment is arranged in the box body.
The filter assembly comprises a partition plate fixedly connected to the inner wall of the box body, a water inlet pipe is communicated below the partition plate, a water outlet pipe is communicated above the partition plate, a central screen and a plurality of movable screens are communicated at the top of the partition plate, electromagnetic valves are communicated at the joints of the water inlet pipe and the box body, and the adjusting system is also used for controlling the opening and closing of the corresponding electromagnetic valves according to the required drainage.
The top wall of the box body is also provided with a scraping component for scraping the sediment on the central screen, a vibrating component for vibrating the sediment on the movable screen and an adjusting component for discharging adjusting solution, and the bottom of the box body is provided with a discharging component for discharging the sediment.
The technical principle of the scheme is as follows:
Because the inner wall of the box body is fixedly connected with the partition plate, the top of the partition plate is communicated with the central screen and the movable screen, so that the external water can pass through the central screen and the movable screen after flowing into the box body, the central screen and the movable screen are utilized to filter the water body, and slag, sediment and the like in the water body are intercepted. After the filtration is finished, the electromagnetic valves corresponding to the water outlet pipes are opened, the water body is discharged to the designated position, the electromagnetic valves can be sequentially opened by utilizing the regulating system according to the drainage quantity, and the drainage requirements of different flow rates are met by utilizing the channels. In the drainage process, when sediment treatment is needed, sediment in the central screen and the movable screen is scraped through the scraping component and the vibrating component, the sediment is discharged through the discharging component, and when a certain part of the screens fail, the rest of the screens are used for continuous filtration, so that the drainage requirement of underground operation of a coal mine is met.
The adoption of the scheme has the following beneficial effects:
1. The invention adopts a composite filtering structure with a plurality of groups of screens, the box body is divided into an upper chamber and a lower chamber by the partition board, and water can enter the water outlet pipe after being filtered by the screens. When underground water burst occurs in a coal mine, a large amount of impurities such as cinder, sediment and the like are often carried in the water body, and a single screen is easy to fail due to blockage or local damage. Under the redundant design of multiple groups of screens, even if one screen cannot work normally due to sediment accumulation, the other screens can still maintain filtering, so that drainage interruption caused by single screen faults is reduced, water is ensured to flow into the upper part of the partition plate through each group of screens, and the water is discharged through the water outlet pipe, and the risk of secondary water damage caused by equipment faults is reduced.

When the initial water quantity is smaller, the pipeline overload is avoided by slowly draining, the medium water quantity is increased rapidly, the draining rate is increased rapidly, the later water level is reduced, and the rate is reduced, so that the energy consumption is saved. In the scheme, the electromagnetic valve of the corresponding water outlet pipe is opened or closed by utilizing the adjusting system according to the requirement, so that the water discharging requirements of different rates are met.

One end of the transverse rod 18 is fixedly adhered to the movable plate 17, so that the movable plate 17 moves synchronously with the reciprocating movement of the transverse rod 18.
Taking fig. 6 as an example, when the transverse rod 18 drives the movable plate 17 to slide rightwards, the internal space of the piston cylinder 16 is compressed and the pressure is increased, the one-way valve at the joint of the output pipe and the piston cylinder 16 is opened due to the pressure effect (the regulating solution flows out), the regulating solution in the piston cylinder 16 is extruded into the output pipe and is injected into the box body 1 through the output pipe, and the one-way valve at the joint of the input pipe and the piston cylinder 16 is closed due to the reverse pressure (the solution backflow is prevented).
When the movable plate 17 slides leftwards, the internal space of the piston cylinder 16 expands to form negative pressure, the one-way valve at the joint of the input pipe and the piston cylinder 16 is opened (the regulating solution flows in) under the action of the negative pressure, the regulating solution released in advance by the electric control valve in the storage tank 19 is sucked into the piston cylinder 16 through the input pipe, and the one-way valve at the joint of the output pipe and the piston cylinder 16 is closed under the action of reverse negative pressure (the liquid in the box body 1 is prevented from being sucked backwards).
Through the synergistic effect of the reciprocating sliding of the movable plate 17 and the one-way valve, the adjusting component realizes the circulation action of adjusting the solution suction and discharge, quantitatively conveys the adjusting solution in the storage tank 19 into the box body 1, and completes the adjustment of the water quality of the water body in cooperation with the analysis result of the adjusting system (the adjusting system controls the opening and closing of the electric control valve).
The discharging assembly comprises a turbidity sensor fixedly adhered to the inner bottom wall of the box body 1, a drain pipe 20 is further communicated with the bottom of the box body 1, a drain valve is communicated with the joint of the drain pipe 20 and the box body 1, and the adjusting system is used for receiving turbidity information of the turbidity sensor and controlling the opening and closing of the drain valve based on the turbidity information.
Specifically, turbidity information (such as sediment content, suspended matter concentration and the like) of the water body is continuously monitored in real time through a turbidity sensor at the inner bottom wall of the box body 1, and monitoring data are transmitted to the regulating system in the form of an electric signal. After the turbidity information is received by the adjusting system, the turbidity information is compared with a preset turbidity discharge threshold value for analysis. If the monitored turbidity value is more than or equal to the set threshold value (indicating that the water body meets the discharge requirement, such as that sediment is fully separated), the regulating system sends an opening instruction to the drain valve, the drain valve opens a connecting channel between the drain pipe 20 and the box body 1, and sediment sewage and the like at the bottom of the box body 1 are discharged through the drain pipe 20.
The specific implementation process is as follows:
Firstly, before draining, the electromagnetic valve of the water inlet pipe is opened according to the drainage requirement, external mixed water enters the space below the partition plate 2 of the box body 1, upwards permeates through the central screen 3 and the movable screen 4 (which are filter components), sediment is intercepted in the central screen 3 and the movable screen 4, and filtered water is discharged through the water outlet pipe above the partition plate 2 (corresponding electromagnetic valve is controlled to be opened by the regulating system).
When the central screen 3 is reduced in filtering efficiency due to sediment adhesion, the regulating system controls the rotating part 9 to start, the output shaft of the rotating part 9 rotates through the toggle rod 12 to drive the movable rod 11 to reciprocate, so that the rack 10 is driven to reciprocate, the gear 6 is driven to rotate forward and backward alternately, the scraper 8 is driven to scrape sediment through the rotating shaft 7 when the gear 6 rotates, meanwhile, the rack 10 reciprocates to drive the vibrating block 15 in the movable screen 4 to vibrate at high frequency through the vertical rod 14, loose sediment is prevented from being blocked, and the sediment falls to the bottom of the partition plate 2.
And when the rack 10 moves, the regulating system controls the corresponding storage tank 19 to open an electric control valve through a preset regulating solution channel, the rack 10 drives the movable plate 17 to slide back and forth in the piston cylinder 16 through the transverse rod 18, the regulating solution is extruded and injected into the box body 1 when the movable plate 17 moves, and the new regulating solution is sucked in when the movable plate moves reversely, so that quantitative conveying is realized. In the process, the turbidity sensor monitors the turbidity of the water body in real time, and if the turbidity is detected to be larger than a preset threshold value, the adjusting system starts the drain valve to drain sediment and sewage.
In the embodiment, the sediment treatment flow of interception, cleaning and discharge is formed through the integrated design of each component. The underground environment of the coal mine is severe, the filtering efficiency of each screen is easily reduced due to sediment adhesion, and the traditional device needs to be manually stopped for cleaning, so that the drainage timeliness is affected. In this scheme, when each screen cloth surface silt pile up to a certain extent, the multiple design of scraper blade 8 and vibrating mass 15 for silt is scraped to baffle 2 below, breaks away from each screen cloth surface. The fallen silt is finally discharged intensively through the drain pipe 20 at the bottom of the tank body 1. The dynamic cleaning mechanism can reduce manual intervention, can synchronously complete maintenance of each screen in the drainage process, reduces equipment shutdown frequency and manual inspection cost, and is suitable for underground narrow areas or long-term unattended emergency drainage scenes.
Example 2:
As shown in figure 2, the difference with the embodiment is that the inner walls of the water inlet pipe and the water outlet pipe are fixedly adhered with pressure sensors, and the adjusting system is used for receiving pressure information sent by the pressure sensors and controlling the opening and closing of the corresponding electromagnetic valve and the water outlet valve based on the pressure information.
The pressure sensor is used for monitoring the water pressure change in the pipeline in real time, the regulating system dynamically regulates and controls the opening and closing of the electromagnetic valve and the drain valve through pressure information, the pressure difference in the box body 1 is changed, the automatic management of the pressure is realized, and a back flushing mechanism is triggered. When the pressure exceeds a preset threshold value, the corresponding electromagnetic valve can be closed, the drainage valve is opened to release pressure and dredge, the water body reversely flows to one side of the drainage valve, sediment and the like in the water body reversely flows to the bottom of the box body 1 by changing the water flow direction, the water body containing the sediment is discharged by utilizing the drainage pipe 20, impurities such as the sediment in each screen mesh are effectively removed, and the operation reliability of the device is improved.
Example 3:
as shown in fig. 2, the difference from the above embodiment is that the vibrating masses 15 on the side near the center screen 3 are each extended to the outside of the movable screen 4, and the vibrating masses 15 are each capable of contacting the outer wall of the center screen 3 when the vertical rod 14 reciprocates.
The concrete implementation process is that the vibrating block 15 contacts with the outer wall of the central screen 3 when reciprocating along with the vertical rod 14, and the generated high-frequency vibration is synchronously transmitted to the outer side of the extending and covering movable screen 4 to form a double-screen linkage blockage removing mechanism. Compared with a single screen vibration design, the structure realizes synchronous blocking removal of double screens through the extending contact of the vibrating blocks 15, can maintain the transparent state of each screen without an additional power device, improves the continuity and stability of screening operation, and reduces equipment maintenance frequency and operation energy consumption.
Example 4:
As shown in fig. 7, the difference from the above embodiment is that the adjustment system includes an information acquisition module for acquiring data, a decision control module for analyzing the data, a logic execution module for controlling the operation of the apparatus, and an early warning interaction module for providing hierarchical early warning.
The functions of each module are as follows:
The information acquisition module is used for acquiring turbidity information (turbidity sensor), pH information (through the pH sensor) and pressure information (pressure sensor) when the device is operated, and transmitting the acquired turbidity information, pH information and pressure information to the decision control module. In the embodiment, the collected turbidity information, pH information and pressure information are uploaded to the decision control module in real time through the RS485 bus, so that the timeliness of data is ensured.
The decision control module is used for analyzing the turbidity data of the water body, the pressure difference delta P between the water inlet pipe and the water outlet pipe and the pH value information of the water body according to the turbidity information, the pH information and the pressure information, outputting an analysis result and transmitting the analysis result data to the logic execution module. In the example, turbidity analysis judges whether the water body reaches the standard or not by comparing the real-time turbidity value with a discharge threshold (e.g. 150 NTU), if the turbidity is greater than or equal to the threshold value for continuous 3 times of sampling, the water body is marked as being dischargeable, and if the turbidity is smaller than the threshold value and delta P is abnormal (e.g. more than 0.5 MPa), the water body is marked as being blocked by the screen and needs to be cleaned. The pressure difference analysis is carried out by calculating delta P and comparing the delta P with a safety threshold (such as 0.3 MPa), if delta P is more than 0.3MPa and turbidity does not reach the standard, the filtration efficiency is judged to be reduced, and the scraper 8 and the vibrating block 15 are required to be triggered to clean the screen. The pH analysis generates an instruction to add an alkaline solution by comparing the real-time pH value with a target range (e.g., 6.5-8.5), if the pH is <6.5 (meta-acid), and generates an instruction to add an acidic solution if the pH is >8.5 (meta-base).
The logic execution module is used for obtaining the analysis result of the decision control module, controlling the opening and closing of the corresponding electromagnetic valve based on the analysis result, controlling the opening and closing of the drain valve based on the turbidity data, and controlling the opening and closing of the corresponding electric control valve based on the pH value information. In this embodiment, according to the differential pressure result (for example, Δp >0.3 MPa), the electromagnetic valve of part of the water outlet pipe is closed (the water outlet amount is reduced), the internal pressure of the tank 1 is reduced, and if Δp returns to normal, the electromagnetic valve is gradually opened to restore the water outlet efficiency. If the turbidity analysis mark is dischargeable, the water discharge valve is immediately opened, and sediment sewage at the bottom of the box body 1 is discharged. If the pH analysis needs to be regulated (such as meta-acid), an electric control valve corresponding to the alkaline solution storage tank 19 is opened, the solution is injected into the box body 1 through the piston cylinder 16, and the electric control valve is closed after the pH value returns to the target range.
The early warning interaction module is used for setting a grading response threshold according to the analysis result output by the decision control module, and triggering the on-off of the corresponding component of the device when the corresponding grading response threshold is reached. Specifically, for example, if the turbidity is close to the threshold (140-150 NTU) or the pH is slightly deviated (6.0-6.5 or 8.5-9.0), the triggering device locally displays a yellow prompt, and sends notice of observation to the mobile phone APP of the operation and maintenance personnel through a wireless network without stopping the machine, and triggers the rotating member 9 to start so as to clean the silt of each screen. If the turbidity exceeds the standard but is not continuous (150-160 NTU) or delta P is abnormal (0.3-0.5 MPa), triggering the water discharge valve to start to discharge sediment, and simultaneously sending a work order to be manually confirmed to the monitoring platform.
