[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0033] First Embodiment

[0034] Please refer to the following: Figure 1 and Figure 2 In the first embodiment of the present invention, the intelligent flushing system for sewage ditches includes: a PLC controller, an information chip transmitter, an information chip receiver, a water pump, an electric valve, a nozzle 3, and a manual switch. The manual switch can manually shut off the water pump and the nozzle 3 when the PLC controller, the information chip transmitter, or the information chip receiver malfunctions. The PLC controller is connected to the information chip transmitter, the information chip transmitter is connected to the information chip receiver, the information chip receiver is connected to the electric valve, and the electric valve is connected to the water pump and the nozzle.

[0035] Compared with related technologies, the intelligent flushing system for sewage ditches provided by this invention has the following beneficial effects:

[0036] The PLC controller, information chip transmitter, and information chip receiver enable remote control of water pumps and electric valves. This allows the water pumps to be turned on remotely at set times, so that water can be sprayed through nozzles to clean the coal sludge deposited in the sewage ditch, thus preventing the coal sludge from clogging the sewage ditch.

[0037] Second embodiment:

[0038] Please refer to the second embodiment. Figure 3-8 The second embodiment of the present invention also provides another intelligent flushing system for sewage ditches.

[0039] In one optional embodiment, the intelligent flushing system for the sewage ditch may include a PLC controller, an information chip transmitter, an information chip receiver, a water pump, an electric valve, a nozzle 3, and a manual switch. The system also includes the nozzle 3 installed within the sewage ditch 1. A temporary storage tank 2 is located at one end of the sewage ditch 1. A first support plate 4 is located above the temporary storage tank 2. An mounting plate 5 is fixedly installed below the first support plate 4. Multiple support rods are fixedly installed on the top of the mounting plate 5, and the top ends of the support rods are fixedly connected to the first support plate 4. A wastewater treatment device is fixedly installed on the mounting plate 5. A mud pump 6 is provided. A support ring 7 is provided above the temporary storage tank 2. A first gear 8 is rotatably installed on the inner wall of the support ring 7. A bearing is fixedly sleeved on the outer wall of the first gear 8. The outer wall of the bearing is fixedly connected to the inner wall of the support ring 7. A motor 9 is provided above the temporary storage tank 2. A second gear 10 is fixedly installed on the output shaft of the motor 9. The second gear 10 meshes with the first gear 8. A plurality of scrapers 11 arranged in a ring are fixedly installed at the bottom of the first gear 8. In this embodiment, the number of scrapers 11 is 5. The scrapers 11 are adapted to the inner wall of the temporary storage tank 2.

[0040] The temporary storage tank 2 is designed in the shape of an inverted frustum. By designing the temporary storage tank 2 in the shape of an inverted frustum, it is possible to facilitate the movement of the coal sludge settled in the temporary storage tank 2 towards the center of the temporary storage tank 2, thereby making it easier for the sludge pump 6 to extract the coal sludge.

[0041] The nozzles 3 are arranged in multiple groups in the sewage ditch 1, and each group includes multiple nozzles 3. The multiple nozzles 3 are fixedly installed on the same support rod.

[0042] In another optional embodiment, the intelligent flushing system for the sewage ditch may not include a PLC controller, an information chip transmitter, or an information chip receiver; it only needs to be able to control the water pump and the electric valve.

[0043] In another optional embodiment, the intelligent flushing system for the sewage ditch may also include existing electronic devices or functional modules to replace the PLC controller, information chip transmitter, and information chip receiver, and achieve the same functions as the aforementioned modules. It is sufficient that the existing electronic devices or functional modules can control the water pump and electric valve.

[0044] When cleaning the coal sludge settled in the temporary storage tank 2, simply start the sludge pump 6 to extract the settled sludge. When the coal sludge around the sludge pump 6 is extracted and the sludge far away from the sludge pump 6 cannot move to the vicinity of the sludge pump 6, start the motor 9. The motor 9 drives the second gear 10 to rotate, the second gear 10 drives the first gear 8 to rotate, and the first gear 8 drives the scraper 11 to move, thereby scraping the sludge in the temporary storage tank 2. At the same time, the temporary storage tank 2, which is set in an inverted frustum shape, can make the sludge far away from the sludge pump 6 move closer to the sludge pump 6, thereby facilitating the extraction of coal sludge by the sludge pump 6.

[0045] Third embodiment:

[0046] Based on the intelligent sewage ditch flushing system provided in the second embodiment of this application, the third embodiment of this application proposes another intelligent sewage ditch flushing system. The third embodiment is merely a preferred embodiment of the second embodiment, and the implementation of the third embodiment will not affect the separate implementation of the second embodiment.

[0047] The third embodiment of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0048] Please refer to the following: Figure 7-10 The intelligent flushing system for sewage ditches also includes a first sludge settling thickness measuring device installed in the temporary storage tank 2. The first sludge settling thickness measuring device is used to measure the sludge settling thickness. When the sludge settling thickness reaches a set height, the sludge pump 6 is started to clean the sludge in the temporary storage tank 2.

[0049] The first sludge settling thickness measuring device includes a second support plate 12 fixedly installed on one side of the mounting plate 5. A collection cylinder 13 is fixedly installed on the top of the second support plate 12. A float 14 is slidably and sealed inside the collection cylinder 13. The air pressure in the space below the bottom of the float 14 inside the collection cylinder 13 is greater than the air pressure in the space above the top of the float 14 inside the collection cylinder 13, so that the float 14 floats inside the collection cylinder 13, thereby causing the two first copper plates 16 to disengage. An insulating plate 15 is fixedly installed on the bottom of the float 14 and the bottom inner wall of the collection cylinder 13. The first copper plates 16 are fixedly installed on the side of the two insulating plates 15 that are close to each other. Multiple ropes 17 are fixedly installed on the bottom of the float 14 and the bottom inner wall of the collection cylinder 3. The ropes 17 are used to limit the highest position of the float 14 inside the collection cylinder 3, thereby preventing the float 14 from moving out of the collection cylinder 3.

[0050] A first air pipe 18 is fixedly installed on one side of the collection cylinder 13. The first air pipe 18 is located below the horizontal plane of the float 14, and the end of the first air pipe 18 away from the collection cylinder 13 extends to the first support plate 4.

[0051] One end of the first air pipe 18 away from the collection cylinder 13 is fixedly installed with a digital pressure gauge 19. The other end of the digital pressure gauge 18 is fixedly installed with an air valve 20. The other end of the air valve 20 is fixedly installed with an air pump 21. The digital pressure gauge 9 is used to display the air pressure in the space below the bottom of the float 14 inside the collection cylinder 13.

[0052] Each of the two first copper plates 16 is connected to a first wire, which passes through the collection cylinder 13 and is sealed to the collection cylinder 13. The first wire of the first copper plate 16 connected to the float 14 has a margin, which allows the first wire to be electrically connected to the first copper plate 16 when the float 14 moves. The first wire can be connected to a PLC controller or directly to the motor 9 and the sludge pump 6, as long as the motor 9 and the sludge pump 6 can be started when the two first copper plates 16 are in contact.

[0053] The first support plate 4 has a through hole, and the first air pipe 18 passes through the through hole and is fixedly connected to the inner wall of the through hole.

[0054] When installing the first sludge settling thickness measuring device in the temporary storage tank 2, the device can be tested first before installation. After the first sludge settling thickness measuring device is installed, when the coal sludge in the temporary storage tank 2 settles in the collection cylinder 13, the downward pressure on the float 4 increases. As more and more sludge settles, the float 4 moves downward until the two first copper plates 6 come into contact. At this time, the motor 9 and the sludge pump 6 start to clean the settled coal sludge in the temporary storage tank 2.

[0055] When it is necessary to adjust the thickness of the sludge sludge in the temporary storage tank 2 after the sludge pump 6 automatically starts cleaning, simply operate the air pump 21. The air pump 21 increases the air pressure in the space below the bottom of the float 14 in the collection cylinder 13 through the air valve 20, the digital pressure gauge 19, and the first air pipe 18, thereby increasing the thickness of the sludge sludge in the temporary storage tank 2 after the sludge pump 6 automatically starts cleaning. After the air pump 21 is turned off, the air valve 20 is opened to discharge the gas in the space below the bottom of the float 14 in the collection cylinder 13, thereby reducing the air pressure in the space below the bottom of the float 14 in the collection cylinder 13, thereby decreasing the thickness of the sludge sludge in the temporary storage tank 2 after the sludge pump 6 automatically starts cleaning.

[0056] After the sludge in the temporary storage tank 2 is cleaned, the coal sludge in the collection cylinder 13 can be flushed out using the high-pressure water gun (not shown in the figure) located directly above the collection cylinder 13 to re-monitor the sludge thickness in the temporary storage tank 2.

[0057] Fourth embodiment:

[0058] Based on the intelligent flushing system for sewage ditches provided in the fourth embodiment of this application, the fourth embodiment of this application proposes three other intelligent flushing systems for sewage ditches. The fourth embodiment is merely a preferred embodiment of the third embodiment, and the implementation of the fourth embodiment will not affect the separate implementation of the third embodiment.

[0059] The fourth embodiment of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0060] Please refer to the following: Figure 11-14 The intelligent flushing system for sewage ditches also includes a second sludge settling thickness measuring device fixedly installed inside the sewage ditch 1. The second sludge settling thickness measuring device is used to measure when the set sludge thickness exceeds the set height, and then start the sludge pump 6 to clean the sludge in the sewage ditch 1.

[0061] The second sludge settling thickness measuring device includes a support pipe 22 fixedly installed on the bottom inner wall of the sewage ditch 1. A rotating plate 23 is rotatably installed inside the support pipe 22. One end of a spring 24 is fixedly installed on one side inner wall of the rotating plate 23, and the other end of the spring 24 is fixedly installed on the side wall of the support pipe 22. The spring 24 is used to provide a thrust to the rotating plate 27. In other embodiments, a torsion spring can be used to apply the thrust to the rotating plate 27. A support rod 25 is fixedly installed on the top of the rotating plate 23. The support rod 25 is rotatably and sealingly connected to the support pipe 22. The top end of the support rod 25 extends to the outside of the support pipe 22 and is fixedly installed with a connecting block 26. The rotating plate 27 is fixedly installed on the outer wall of the connecting block 26. An inflation mechanism is fixedly installed on the bottom inner wall of the sewage ditch 1. The inflation mechanism is equipped with an alarm mechanism and is connected to the rotating plate 27.

[0062] The inflation mechanism includes a fixed plate 34 fixedly installed on the inner wall of the bottom of the sewage ditch 1. An air cylinder 28 is fixedly installed on the fixed plate 34. A second air pipe 35 is fixedly installed on the air cylinder 28. The second air pipe 35 can be connected to another pipe from the inflation pump 21, and an air valve 20 can be set on the pipe. Alternatively, a new inflation pump 21 can be connected. An air hole 30 is opened on the air cylinder 28. The second air pipe 35 is connected to the air cylinder 28 through the air hole 30. A push rod 29 is slidably and sealed inside the air cylinder 28. The push rod 29 includes a connecting rod, a sliding sealing block, and a push block. The two ends of the connecting rod are respectively connected to the sliding sealing block and the push block. Two limiting blocks are fixedly installed inside the air cylinder 28. In the initial state, the air pressure inside the air cylinder 28 is less than the elastic force of the spring 24. At this time, the sliding sealing block is in contact with the limiting block away from the rotating plate 27. One end of the push rod 29 extends to the outside of the air cylinder 28 and is in contact with the rotating plate 27.

[0063] The alarm mechanism includes a connecting cylinder 31 fixedly installed on the air cylinder 28. A third support plate 32 is fixedly installed on the connecting cylinder 31. A sealing plate 36 is slidably and sealed inside the connecting cylinder 31. The sealing plate 36 is located between the third support plate 32 and the air cylinder 28. A second copper sheet 33 is fixedly installed between the sealing plate 36 and the third support plate 32. A second wire is connected to each of the two copper sheets 33. The second wire passes through the connecting cylinder 31 and is fixedly and sealed to the connecting cylinder 31. The second wire on the second copper sheet 33 connected to the sealing plate 36 has a margin to ensure electrical connection between the second wire and the second copper sheet 33 when the second copper sheet 33 moves. The second wire can be connected to a PLC controller or directly to a water pump, as long as the water pump can be started when the two first copper sheets 16 are in contact.

[0064] The internal space of the connecting cylinder 31 of the sealing plate 26, which is away from the gas cylinder 28, is filled with a certain amount of gas.

[0065] When using the second sludge settling thickness measuring device to measure the thickness of coal sludge in the sewage ditch, simply start the air pump 21. The air pump 21 fills the air cylinder 28 with gas through the air valve 20 and the second air pipe 35. As the gas in the air cylinder 28 increases, the pressure applied by the push rod 29 to the rotating plate 27 gradually increases until the force applied by the push rod 29 to the rotating plate 27 is greater than the elastic force of the spring 24. At this point, the rotating plate 27 rotates until the push rod 29 pushes the rotating plate 27 to move and then suddenly contacts the rotating plate 27. During separation, the push rod 29 moves to its maximum extension position. As the air pump 24 continues to pressurize, the pressure inside the air cylinder 28 gradually increases. When the pressure inside the air cylinder 28 is greater than the pressure inside the connecting cylinder 31 of the sealing plate 26 away from the air cylinder 28, the sealing plate 36 begins to move towards the support plate 32 until the two second copper plates 33 come into contact. After 3 seconds, the air pump 24 is turned off and the water pump is started, so that water is sprayed out from the nozzle 3 to clean the coal sludge in the drainage ditch 1.

[0066] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
