Description

Technical Field

[0001] The present invention belongs to the technical field of drainage equipment, and particularly relates to a tunnel sewage anti-blocking discharge device. Background Art

[0002] A tunnel refers to an engineering structure buried in the stratum, which is a form of human utilization of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mine tunnels, military tunnels, etc.

[0003] During the open-cut process of a tunnel, a large amount of sewage containing sediment and sludge will be generated. For the convenience of construction, the sewage needs to be discharged and treated. However, currently, during the tunnel sewage discharge process, a drain pipe is usually used for remote drainage, and the drain pipe drainage will occupy a large amount of space in the tunnel, increasing the labor intensity of workers, and the discharged sewage cannot be collected and utilized. If a water pump or other equipment is used for direct pumping, since there are impurities such as clay with strong adhesion in the sewage, the impurities are mixed with each other, easily blocking the equipment and causing the device to be unable to drain water normally. Summary of the Invention

[0004] The purpose of the embodiments of the present invention is to provide a tunnel sewage anti-blocking discharge device, aiming to solve the problems proposed in the above background art.

[0006] A drainage part, the drainage part includes a sewage storage tank, a hollow floating plate is slidably installed in the sewage storage tank, and a stop block for placing the hollow floating plate is installed in the sewage storage tank. A filter plate is also installed in the hollow floating plate. A drainage assembly for pumping out the sewage in the sewage storage tank is arranged on the sewage storage tank, and the drainage assembly is connected to the hollow floating plate;

[0007] A water pumping part, the water pumping part includes a second water pump installed on the base. The second water pump is connected with a water inlet pipe and a water outlet pipe. The water outlet pipe is inserted into the interior of the sewage storage tank. One end of the water inlet pipe away from the second water pump is connected with an anti-blocking pipe, and a water pumping cover is arranged at the bottom of the anti-blocking pipe; and

[0008] An anti-blocking assembly, the anti-blocking assembly includes an anti-blocking sleeve slidably installed in the anti-blocking pipe. A hollow damping plate is arranged at the top of the anti-blocking sleeve. Guide rods are annularly installed on the outer side wall of the anti-blocking sleeve, and spiral guide grooves matching the guide rods are opened on the inner wall of the anti-blocking pipe. A number of inclined stirring rods are annularly installed on the inner wall of the anti-blocking sleeve.

[0009] Further technical solution: The drainage assembly includes a first water pump installed on the sewage storage tank. The first water pump is respectively connected with a first telescopic pipe and a drain pipe. The first telescopic pipe is inserted into the interior of the sewage storage tank, and one end of the first telescopic pipe away from the first water pump is connected with a hollow floating plate through a connecting cover, and the connecting cover is installed above the filter plate.

[0010] Further technical solution: A flushing assembly for flushing water into the anti-blocking pipe is also connected between the drain pipe and the anti-blocking pipe.

[0011] Further technical solution: The flushing assembly includes a connecting pipe. One end of the connecting pipe is connected with the drain pipe through a three-way pipe, and an electric control one-way valve is also arranged on the drain pipe. The other end of the connecting pipe is also communicated with the anti-blocking pipe through a three-way pipe, and an electric control one-way valve is also arranged at the connection of the connecting pipe and the anti-blocking pipe.

[0012] Further technical solution: The anti-blocking pipe is connected with the water inlet pipe through a second telescopic pipe, and a lifting assembly for driving the anti-blocking pipe to perform linear motion in the vertical direction is also arranged on the base.

[0013] Further technical solution: The lifting assembly is installed on the base through a vertically arranged mounting plate. The lifting assembly includes a motor installed on the mounting plate.

A fixed seat is arranged on the slider, and the anti-blocking pipe is installed in the fixed seat.

[0014] Further technical solution: A first induction sheet is installed on the upper end surface of the block, and a second induction sheet is correspondingly arranged at the bottom of the hollow floating plate, and the first induction sheet and the second induction sheet are in contact with each other.

[0015] A tunnel sewage anti-blocking discharge device provided by an embodiment of the present invention, when in use, insert the anti-blocking pipe and the pumping cover into the sewage, start the second water pump. Under the action of the second water pump, the sewage will enter the anti-blocking pipe through the pumping cover.

Even if the impurities are not dispersed, since the anti-blocking sleeve is close to the end of the anti-blocking pipe, it is also convenient to remove the impurities blocked by the damping plate. The sewage can enter the sewage storage tank through the water outlet pipe, and then precipitation can be carried out in the sewage storage tank. When the liquid level of the sewage contacts the lower surface of the hollow floating plate, the first water pump can discharge the sewage from the drain pipe through the first telescopic pipe and the connecting cover, and the sewage will also pass through the filter plate before entering the connecting cover, which can effectively reduce the impurity content in the sewage. This device can efficiently discharge sewage and can effectively prevent blockage during the drainage process without manual dredging, greatly improving the work efficiency.

Detailed implementation mode

[0022] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0024] As Figures 1-4 shown, a tunnel sewage anti-blocking discharge device provided by an embodiment of the present invention includes a base 1. A crawler mobile mechanism 11 is provided at the bottom of the base 1, which can adapt to the ground environment in the tunnel. It also includes:

[0025] A drainage part 2, the drainage part 2 includes a sewage storage tank 21. A hollow floating plate 22 is slidably installed in the sewage storage tank 21, and a stop block 23 for placing the hollow floating plate 22 is installed in the sewage storage tank 21. A filter plate 24 is also installed in the hollow floating plate 22. A drainage component for pumping out the sewage in the sewage storage tank 21 is provided on the sewage storage tank 21, and the drainage component is connected to the hollow floating plate 22;

[0026] A pumping part 3, the pumping part 3 includes a second water pump 31 installed on the base 1. The second water pump 31 is connected with a water inlet pipe 32 and a water outlet pipe 36. The water outlet pipe 36 is inserted into the interior of the sewage storage tank 21. One end of the water inlet pipe 32 far from the second water pump 31 is connected with an anti-blocking pipe 33, and a pumping hood 35 is provided at the bottom of the anti-blocking pipe 33; and

[0027] An anti-blocking component 5, the anti-blocking component 5 includes an anti-blocking sleeve 51 slidably installed in the anti-blocking pipe 33. A hollow damping plate 55 is provided at the top of the anti-blocking sleeve 51. Guide rods 53 are annularly installed on the outer side wall of the anti-blocking sleeve 51, and a spiral guide groove 54 matching the guide rods 53 is opened on the inner wall of the anti-blocking pipe 33. A number of obliquely arranged stirring rods 52 are annularly installed on the inner wall of the anti-blocking sleeve 51.

[0028] In the embodiment of the present invention, during use, the anti-blocking pipe 33 and the pumping cover 35 are inserted into the sewage. The second water pump 31 is started. Under the action of the second water pump 31, the sewage will enter the anti-blocking pipe 33 through the pumping cover 35. When the impurity content in the sewage is too high, the sewage will push the anti-blocking sleeve 51 to slide along the inner wall of the anti-blocking pipe 33. Under the combined action of the guide rod 53 and the spiral guide groove 54, the anti-blocking sleeve 51 will rotate. The anti-blocking sleeve 51 drives the stirring rod 52 to beat the impurities in the sewage, so that the impurities are dispersed, reducing the occurrence of blockage. At the same time, the damping plate 55 can play a damping role and can block the impurities in the sewage, so that the impurities that may block the pipeline will be blocked in the anti-blocking sleeve 51 in advance, and the impurities are beaten in the anti-blocking sleeve 51 until the impurities are dispersed, which can greatly reduce the possibility of blockage in the subsequent pipeline. Even if the impurities are not dispersed, since the anti-blocking sleeve 51 is close to the end of the anti-blocking pipe 33, it is also convenient to remove the impurities blocked by the damping plate 55. The sewage can enter the sewage storage tank 21 through the water outlet pipe 36, and then precipitation can be carried out in the sewage storage tank 21. When the liquid level of the sewage contacts the lower surface of the hollow floating plate 22, the first water pump 25 can discharge the sewage from the drain pipe 28 through the first telescopic pipe 26 and the connecting cover 27. And the sewage will also pass through the filter plate 24 before entering the connecting cover 27, which can effectively reduce the impurity content in the sewage.

[0029] As Figure 1 and 5 shown, as a preferred embodiment of the present invention, the drainage assembly includes a first water pump 25 installed on the sewage storage tank 21. The first water pump 25 is respectively connected with a first telescopic pipe 26 and a drain pipe 28. The first telescopic pipe 26 is inserted into the sewage storage tank 21, and one end of the first telescopic pipe 26 away from the first water pump 25 is connected with a connecting cover 27. The connecting cover 27 is installed on the hollow floating plate 22, and the connecting cover 27 is located above the filter plate 24.

[0030] In the embodiment of the present invention, during use, the first water pump 25 pumps out the sewage inside the sewage storage tank 21 through the first telescopic pipe 26. Under the combined action of the filter plate 24 and the connecting cover 27, the precipitated sewage will be filtered and then enter the first telescopic pipe 26. And as the hollow floating plate 22 floats up and down, the first telescopic pipe 26 will expand and contract, always ensuring the normal discharge of the sewage. The first water pump 25 can transport the sewage conveyed by the first telescopic pipe 26 to the drain pipe 28, and then discharge the sewage through the drain pipe 28.

[0031] As Figure 1 and 2 shown, as a preferred embodiment of the present invention, a flushing assembly 6 for flushing water into the anti-blocking pipe 33 is further connected between the drain pipe 28 and the anti-blocking pipe 33.

[0032] In an embodiment of the present invention, the flushing assembly 6 includes a connecting pipe 61. One end of the connecting pipe 61 is connected to the drain pipe 28 through a tee pipe 62, and an electronically controlled one-way valve 63 is further provided on the drain pipe 28, and the electronically controlled one-way valve 63 is in an open state. The other end of the connecting pipe 61 is also connected to the anti-blocking pipe 33 through a tee pipe 62, and an electronically controlled one-way valve 63 is also provided at the connection between the connecting pipe 61 and the anti-blocking pipe 33, and the electronically controlled one-way valve 63 is in a normally closed state.

[0033] When a blockage occurs at the damping plate 55, the electronically controlled one-way valve 63 on the drain pipe 28 closes, and at the same time, the electronically controlled one-way valve 63 at the connection between the connecting pipe 61 and the anti-blocking pipe 33 opens. At this time, the water discharged by the first water pump 25 will flow into the connecting pipe 61, and then the water will flow into the anti-blocking pipe 33 through the connecting pipe 61. The impact force of the water flow will disperse the impurities blocked at the damping plate 55, realizing conduction. And the water flow will also push the anti-blocking sleeve 51 to move in the reverse direction synchronously, so as to drive the stirring rod 52 to rotate in the reverse direction synchronously. Under the impact force of the water flow and the stirring action of the stirring rod 52, the blockage can be effectively dispersed. When the blocked place is unclogged, both electronically controlled one-way valves 63 return to their initial states, and at this time, the device can continue to carry out the sewage discharge work.

[0034] As Figure 1 and 2 shown, as a preferred embodiment of the present invention, the anti-blocking pipe 33 is connected to the water inlet pipe 32 through a second telescopic pipe 34, and a lifting assembly 4 for driving the anti-blocking pipe 33 to perform linear motion in the vertical direction is further provided on the base 1.

[0035] In an embodiment of the present invention, when the device is in a non-working state, the lifting assembly 4 can drive the anti-blocking pipe 33 to move upward, so that it is fixed on the device and does not affect the movement of the device. When the device is in a working state, the lifting assembly 4 drives the anti-blocking pipe 33 to move downward, so that both the anti-blocking pipe 33 and the pumping cover 35 are located below the liquid level of the sewage, so as to facilitate pumping.

[0036] As Figure 2 shown, as a preferred embodiment of the present invention, the lifting assembly 4 is installed on the base 1 through a vertically placed mounting plate. The lifting assembly 4 includes a motor 41 installed on the mounting plate. The output end of the motor 41 is connected to a threaded rod 42. A slider 43 is installed on the threaded rod 42, and the slider 43 is slidably installed on the mounting plate. A fixed seat 44 is provided on the slider 43, and the anti-blocking pipe 33 is installed in the fixed seat 44.

[0037] In the embodiment of the present invention, during use, the motor 41 drives the threaded rod 42 to rotate, and the threaded rod 42 drives the slider 43 to slide along its axial direction. The slider 43 drives the anti-blocking pipe 33 to move up and down through the fixed seat 44, thereby realizing the adjustment of the height of the anti-blocking pipe 33. At the same time, as the anti-blocking pipe 33 moves up and down, the second telescopic pipe 34 will expand and contract, so as to always ensure the normal transportation of sewage.

[0038] As Figure 1 shown, as a preferred embodiment of the present invention, a first sensing piece is installed on the upper end surface of the stopper 23, and a second sensing piece is correspondingly arranged at the bottom of the hollow floating plate 22, and the first sensing piece and the second sensing piece are in contact with each other.

[0039] In the embodiment of the present invention, when the device is not working, the hollow floating plate 22 will overlap on the stopper 23. At this time, the first sensing piece and the second sensing piece are in contact with each other, and signal transmission can be always maintained. When the hollow floating plate 22 floats upward, since there is sewage between the hollow floating plate 22 and the stopper 23, the first sensing piece and the second sensing piece still maintain electrical signal transmission. Only when the sediment such as silt in the sewage storage tank 21 is too much, the sewage storage tank 21 will be lifted and the electrical signal transmission between the first sensing piece and the second sensing piece will be disconnected. At this time, the control signal can be used to judge whether the inside of the sewage storage tank 21 needs to be cleaned.

[0040] Working principle: During use, insert the anti-blocking pipe 33 and the pumping cover 35 into the sewage, start the second water pump 31. Under the action of the second water pump 31, the sewage will enter the anti-blocking pipe 33 through the pumping cover 35. When the impurity content in the sewage is too much, the sewage will push the anti-blocking sleeve 51 to slide along the inner wall of the anti-blocking pipe 33. Under the combined action of the guide rod 53 and the spiral guide groove 54, the anti-blocking sleeve 51 will rotate. The anti-blocking sleeve 51 drives the stirring rod 52 to beat the impurities in the sewage, so that the impurities are dispersed, reducing the occurrence of blockage. At the same time, the damping plate 55 can play a damping role and can block the impurities in the sewage, so that the impurities that may block the pipeline will be blocked in the anti-blocking sleeve 51 in advance, and the impurities are beaten in the anti-blocking sleeve 51 until the impurities are dispersed, which can greatly reduce the possibility of blockage in the subsequent pipeline. Even if the impurities are not dispersed, since the anti-blocking sleeve 51 is close to the end of the anti-blocking pipe 33, it is also convenient to remove the impurities blocked by the damping plate 55. The sewage can enter the sewage storage tank 21 through the water outlet pipe 36, and then can be precipitated in the sewage storage tank 21. When the liquid level of the sewage contacts the lower surface of the hollow floating plate 22, the first water pump 25 can discharge the sewage from the drain pipe 28 through the first telescopic pipe 26 and the connecting cover 27, and the sewage will also pass through the filter plate 24 before entering the connecting cover 27, which can effectively reduce the impurity content in the sewage.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
