Description

Technical Field

[0001] The invention relates to the technical field of municipal construction, and in particular to auxiliary equipment for municipal pipe well construction. Background Art

[0002] Municipal pipe wells refer to facilities used to manage underground pipes in cities, usually consisting of a wellbore, a well cover, and a well seat. Through reasonable layout and design, municipal pipe wells have drainage functions and sewage collection and treatment functions, which are used to improve the efficiency of urban operations.

[0003] Usually, municipal pipe wells are mainly used to discharge urban wastewater to ensure the smooth flow of urban drainage systems. However, urban sewage includes domestic sewage and industrial wastewater, which contain a large amount of suspended matter, silt, fiber and other solid substances. These substances will gradually settle at the bottom of the municipal pipe wells during the flow process, forming a silt layer. If not handled in time, the pipe wells will be blocked, resulting in a reduction in the effective water flow area of ​​the pipe wells, or even complete blockage, affecting the normal drainage function. In rainy seasons or flood seasons, it will cause sewage overflow and cause environmental pollution.

[0004] At present, there are two common methods of municipal pipe well dredging: manual cleaning and mechanical cleaning. Manual cleaning mainly relies on staff to use handheld tools for cleaning. Although this method is low-cost, it is inefficient and is usually not advisable for large-scale dredging work. In the case of deep pipe wells and more silt, mechanical dredging is the preferred option. Common mechanical dredging mainly uses a sewage suction truck to suck the silt in the pipe well into the vehicle and then discharge it outside.

[0005] Under normal circumstances, silt removal by suction trucks involves sucking the silt and wastewater mixed together into the truck through an extraction pipe. This method has the following disadvantages: first, the silt is easily blocked after entering the extraction pipe with the water flow; second, the extracted silt needs to be left to stand for treatment to separate the wastewater from the silt, and finally converted into a reusable resource after treatment in an aeration tank, secondary sedimentation tank, etc.; under this method, the collection and separation of silt requires the coordination of multiple equipment, and the process is cumbersome. In addition, the related equipment consumes a lot of energy and has high maintenance costs.

[0006] Based on this, the present invention proposes an auxiliary equipment for municipal pipe well construction to meet the collection and separation of silt in the pipe well, improve work efficiency and reduce energy consumption. Summary of the invention

DETAILED DESCRIPTION

[0027] Next, a specific embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0028] An auxiliary device for municipal pipe well construction includes a stretching frame 1 made of stainless steel pipe with strong load-bearing and high stability. To facilitate the movement of the stretching frame 1, a universal wheel is installed at the bottom of the stretching frame 1. The stretching frame 1 is provided with an electric push rod 11. The telescopic end of the electric push rod 11 is provided with a collection component for collecting sludge and wastewater (hereinafter collectively referred to as sludge). The working principle of this device is to move the stretching frame 1 to the pipe well mouth, start the electric push rod 11 to drive the collection component to fall to the bottom of the pipe well, and collect the sludge first and then separate it.

[0029] As described in the background technology, the conventional silt removal method of suction trucks can easily cause clogging of the extraction pipe. Since the pipe wells are generally several meters to tens of meters below the surface, the suction trucks consume a lot of energy when running. Therefore, the present invention abandons this extraction and collection method and adopts an extrusion method to collect the silt in the pipe well. This solution has low energy consumption and avoids the problems caused by using an extraction pipe to suck the silt. Secondly, the collection work is completed only by the extrusion force generated by the collection component on the silt.

[0030] Specifically, the device is provided with a collecting component on the electric push rod 11, and the collecting component includes a bottom plate 17 axially connected to the telescopic end of the electric push rod 11, and the bottom plate 17 moves up and down with the electric push rod 11. A collecting bucket 14 is provided on the bottom plate 17, and a support block is provided on the bottom plate 17. The support block is in contact with the bottom of the inner wall of the collecting bucket 14, so that the bottom plate 17 drives the collecting bucket 14 to move downward through the support block. A filter plate 18 is provided on the bottom plate 17, and the radius of the bottom plate 17 and the filter plate 18 are consistent and fit. The bottom plate 17 and the filter plate 18 are both slidably connected to the inner wall of the collecting bucket 14, and the filter plate 18 is rotatably connected to the telescopic end of the electric push rod 11. The bottom plate 17, the filter plate 18 and the collecting bucket 14 constitute a collecting tube barrel structure with an open top, and the bottom plate 17 and the filter plate 18 are equivalent to the bottom sealing plate of the collecting bucket 14.

[0031] However, in order to make the silt enter the collection bucket 14 and stay in the collection bucket 14, the present device is realized by the following methods: first, filter holes are opened on the bottom plate 17 and the filter plate 18, and the filter holes on the bottom plate 17 and the filter plate 18 correspond to each other, so that the silt can enter the collection bucket 14 easily. The bottom plate 17 and the filter plate 18 are provided with filter holes with the same number and radius and evenly distributed. When the collection bucket 14 is lowered in the pipe well, the silt can enter the collection bucket 14 through the filter holes. Second, the filter holes on the bottom plate 17 and the filter plate 18 are arranged to be uniformly distributed. The filter holes are arranged in a staggered manner to form a sealing plate, so that the sludge entering the collection barrel 14 is retained inside. Therefore, the device opens a linear slide groove and a curved slide groove on the inner wall of the collection barrel 14, so that the bottom plate 17 and the filter plate 18 move along the linear slide groove and the curved slide groove respectively. During this movement, the bottom plate 17 keeps moving up in a straight line, and the filter plate 18 rotates and moves up at a certain angle, thereby achieving the purpose of forming a sealing plate after the filter holes on the bottom plate 17 and the filter plate 18 are arranged in a staggered manner, thereby achieving the effect of retaining the sludge in the collection barrel 14. For details, refer to Figure 2 The inner wall of the collecting barrel 14 is provided with a linear chute and a curved chute, the bottom plate 17 moves along the linear chute on the inner wall of the collecting barrel 14, and the filter plate 18 moves along the curved chute on the inner wall of the collecting barrel 14. After the sludge collection work is completed, the sludge needs to be left to stand for a period of time to separate the sludge and wastewater, which is convenient for subsequent separation work. It is particularly noted that this standing work is still carried out at the bottom of the pipe well.

[0032] Usually, the pipe well is deep under the surface. In order to facilitate the operation and observation of the subsequent separation work, the collection bucket 14 and the silt layered therein need to be pulled up to the pipe well mouth. Initially, the collection bucket 14 is built into the stretching frame 1, the electric push rod 11 is closed and the telescopic end is in a retracted state, the bottom plate 17 and the filter plate 18 are fitted and both are at the bottom of the collection bucket 14, and the filter holes on the bottom plate 17 and the filter plate 18 are one-to-one corresponding. When working, the stretching frame 1 is moved to the pipe well mouth, and the electric push rod 11 is started, so that the telescopic end of the electric push rod 11 drives the bottom plate 17 to move downward and penetrate into the pipe well, thereby driving the collection bucket 14 and the filter plate 18 to move downward synchronously, and the filter is filtered through the bottom plate 17. The plate 18 and the collecting barrel 14 move downward synchronously, and the extrusion force squeezes the silt in the pipe well into the collecting barrel 14 through the filtering holes on the bottom plate 17 and the filter plate 18, and runs to the bottom of the pipe well. Then, the electric push rod 11 drives the bottom plate 17 to move up a certain distance, and the bottom plate 17 moves upward along the straight slide groove on the inner wall of the collecting barrel 14, thereby driving the filter plate 18 to move up a certain distance along the curved slide groove on the inner wall of the collecting barrel 14 and rotate a certain angle. This process is intended to stagger the filtering holes on the bottom plate 17 and the filter plate 18, so that the bottom plate 17 and the filter plate 18 form a sealing plate on the inner wall of the collecting barrel 14, and the silt is retained inside the collecting barrel 14, thereby completing the silt collection work. , then, the collection bucket 14 and the stratified silt inside it need to be pulled up to the pipe well head together, the specific scheme is as follows: first, a pulling assembly is set on the stretching frame 1 to realize the pulling action of the collection bucket 14, the pulling assembly is arranged on the stretching frame 1, including a support platform 16 installed on the pulling frame 1, a winch is installed on the support platform 16, a pull rope 13 is wound on the winch, and a fixed pulley 12 is provided on the stretching frame 1, and the fixed pulley 12 has the function of not changing the magnitude of the force. This is the prior art and will not be elaborated on here. The pull rope 13 is also wound around the fixed pulley 12, and the free ends of the pull rope 13 are fixedly connected to the top of the collection bucket 14, and the winch can be started to drive the fixed pulley 12 to drive the pull rope 13 to move. The pull rope 1 pulls up the collection bucket 14. Considering that the collection bucket 14 is heavy and located at the bottom of the pipe well, the lifting stroke is long. Therefore, the device sets a winch on the support platform 16 and sets a matching number of fixed pulleys 12 on the stretching frame 1 to cooperate in completing the lifting action of the collection bucket 14. Secondly, by starting the electric push rod 11, the bottom plate 17 moves up to drive the filter plate 18 to move up, and then drives the silt layered thereon to move up. Thirdly, in order to ensure that the silt is always retained in the collection bucket 14, the lifting action of the winch and the electric push rod 11 are started synchronously, so that the collection bucket 14 and the bottom plate 17 and the filter plate 18 move up synchronously, so that the collection bucket 14 and the silt layered therein move up synchronously. In particular, under the control of the collection bucket 14 by its gravity and the relevant personnel in the pipe well, the collection bucket 14 will not rotate at the beginning of this upward movement, so that the filter holes on the bottom plate 17 and the filter plate 18 are arranged in a staggered manner to form a sealing plate.

[0033] After the collecting barrel 14 is moved to the pipe well mouth, the layered silt needs to be separated. The silt is deposited at the bottom of the collecting barrel 14, and the wastewater is deposited above the silt layer. The silt separation scheme of the present invention is to first discharge the wastewater at the top and then collect the silt below.

[0034] First, the device discharges the wastewater layer from the collection barrel 14 in the following manner, and by starting the electric push rod 11, the bottom plate 17 and the filter plate 18 are driven to move upward synchronously, thereby driving the layered silt to move upward. Since the wastewater layer is above the silt layer, as the filter plate 18 continues to move upward, by controlling the upward height of the filter plate 18, the wastewater gradually overflows from the top of the collection barrel 14, while the silt layer remains in the collection barrel 14.

[0035] Specifically, the upward movement stroke of the filter plate 18 can be determined by measuring the thickness of the wastewater layer and the sludge layer. Therefore, the device measures the thickness of the wastewater layer and the sludge layer by setting a measuring component on the stretching frame 1, so as to determine the upward movement stroke of the filter plate 18 and achieve the effect of wastewater overflowing and sludge retention.

[0036] The measuring assembly is arranged on the stretching frame 1, and the measuring assembly includes a section rod 2 fixedly connected to the stretching frame 1, the section rod 2 is provided with a connecting rod 21, the connecting rod 21 is provided with a groove, a scale rod 22 is slidably connected in the groove, the scale rod 22 can slide in the groove of the connecting rod 21, and the scale rod 22 is used to measure the thickness of the stratified silt layer and wastewater layer.

[0037] As described above, the thickness of the stratified silt layer and wastewater layer can be measured by the staff by moving the scale rod 22 downward into the collection barrel 14. In order to make the measurement data have reference value, the length of the scale rod 22 should be set to be greater than or equal to the depth of the collection barrel 14. The scale rod 22 stops when the bottom contacts the filter plate 18. The silt layer and the wastewater layer will leave different marking signals on the scale rod 22.

[0038] After the measurement is completed, it is necessary to calculate the upward height of the filter plate 18 through the marking signals left by the wastewater layer and the silt layer on the scale rod 22 to achieve the effect of completely discharging the wastewater layer. According to common sense, it can be concluded that the marking signal of the silt layer on the scale rod 22 is moved up to the opening of the collection bucket 14. In this process, the upward stroke of the scale rod 22 is equal to the upward stroke of the filter plate 18 that satisfies the complete overflow of the wastewater layer.

[0039] Specifically, the scale rod 22 is pulled upward until the mark signal of the sludge layer on the scale rod 22 is at the same height as the opening of the collection bucket 14, and then the scale rod 22 needs to be stabilized in order to ensure that the upward movement of the filter plate 18 is equal to the upward movement of the scale rod 22. The device fixes the scale rod 22 manually. For details, refer to Figure 4A pin 23 is connected through the scale rod 22, and a socket is provided on the connecting rod 21. The pin 23 passes through the sockets on the scale rod 22 and the connecting rod 21. Before measurement, the pin 23 withdraws from the socket of the connecting rod 21. After measurement, when the marking signal of the silt layer on the scale rod 22 moves up to the opening of the collection bucket 14, pressing the pin 23 can fix the height of the scale rod 22.

[0040] Subsequently, the filter plate 18 moves up until it just touches the bottom of the scale rod 22. During the upward movement of the filter plate 18, the wastewater will gradually overflow. This process is achieved by starting the electric push rod 11 to drive the bottom plate 17 to move up, thereby driving the filter plate 18 to move up until the filter plate 18 just touches the bottom of the scale rod 22 and stops.

[0041] Overflowed wastewater can be recycled again, and after treatment, it can be recycled in agricultural irrigation, urban greening, landscape pools and other fields. At the same time, under normal circumstances, wastewater will irregularly overflow from the opening of the collection barrel 14. In order to prevent the overflowed wastewater from flowing back into the pipe well, it is necessary to collect the overflowed wastewater. The conventional wastewater collection method is to connect an external pipe to the collection barrel 14 for collection. Due to the small internal space of the pipe well, there is a space limitation for connecting an external pipe to the collection barrel 14. Therefore, the present invention abandons this method and collects the wastewater overflowing from the collection barrel 14 by setting a double-layer structure for the collection barrel 14. The specific scheme is as follows: The collecting barrel 14 is composed of an inner wall and an outer wall, the bottom of the inner wall and the outer wall are connected, the top of the inner wall and the outer wall are not in contact, and there is a certain storage space between the inner wall and the outer wall. This inner wall and outer wall structure forms a water storage cavity, which is intended to store overflowed wastewater in the water storage cavity between the inner wall and the outer wall of the collecting barrel 14. Considering that an opening will be formed when the top of the inner wall and the outer wall are not in contact, silt will enter the water storage cavity from the opening at the top of the collecting barrel 14 when the collecting barrel 14 moves. Therefore, a cover plate is provided on the top of the collecting barrel 14, and the cover plate is used to prevent silt from entering the water storage cavity from the opening where the top of the inner wall and the outer wall of the collecting barrel 14 are not in contact.

[0042] However, the wastewater overflowing from the collecting barrel 14 will flow out irregularly along the outer wall of the collecting barrel 14, which is not conducive to collection. In order to make the overflowing wastewater flow into the water storage chamber of the collecting barrel 14 in a directional manner, the device diverts the overflowing wastewater by opening a water inlet hole and a diversion component on the outer wall of the collecting barrel 14, so that the overflowing wastewater enters the water storage chamber of the collecting barrel 14 through the water inlet hole along the diversion component.

[0043] The outer wall of the collecting barrel 14 is provided with evenly distributed water inlet holes, which facilitate wastewater to flow into the water storage chamber. The outer wall of the collecting barrel 14 is provided with a guide assembly for guiding overflowing wastewater into the water inlet hole. The guide assembly includes a blocking ring 33 slidably connected to the collecting barrel 14, and the blocking ring 33 covers the water inlet hole on the outer wall of the collecting barrel 14, aiming to block the water inlet hole. In the initial state, the blocking ring 33 covers the water inlet hole on the outer wall of the collecting barrel 14. When wastewater overflows, it is necessary to cancel the blocking of the water inlet hole by the blocking ring 33. Therefore, the present device adjusts the blocking effect of the blocking ring 33 on the water inlet hole by arranging an adjustment assembly on the collecting barrel 14. The adjustment assembly includes a fixing ring 35 arranged on the outer wall of the collecting barrel 14, and a telescopic column 38 is provided on the fixing ring 35. A sliding ring 31 is provided on the telescopic column 38. A pressure spring 36 is provided between the sliding ring 31 and the fixing ring 35. The pressure spring 36 is wound around the telescopic column 38, and the telescopic column 38 can drive The sliding ring 31 moves up and down with a small amplitude, and a fixed block 34 is provided on the sliding ring 31. The sliding ring 31 is connected to the blocking ring 33 through a connecting piece 32. The blocking ring 33 can be linked with the sliding ring 31. A sliding groove is opened on the stretching frame 1, and a rotating ring 37 is slidably connected in the sliding groove. A wedge block 3 is provided on the rotating ring 37, and the wedge block 3 is squeezed and matched with the connecting piece 32. According to the above explanation, during the upward movement of the filter plate 18, the stratified waste water in the collecting barrel 14 gradually overflows. At this time, it is necessary to cancel the blocking of the water inlet by the blocking ring 33. The specific implementation plan of this cancellation action is as follows: the wedge block 3 is dialed to drive the rotating ring 37 to rotate on the stretching frame 1. Under the squeezing action of the wedge block 3 and the fixed block 34, the fixed block 34 is driven to rotate and move upward along the wedge surface of the wedge block 3, the telescopic column 38 is pulled up, and the pressure spring 36 is deformed, thereby linking the sliding ring 31 and the blocking ring 33 to rotate and move upward synchronously, thereby canceling the blocking of the water inlet by the blocking ring 33.

[0044] At this time, the water inlet holes on the outer wall of the collecting barrel 14 are all opened, and the overflowing wastewater needs to enter the water storage cavity of the collecting barrel 14 from the water inlet holes through the flow channel. Therefore, the device guides the overflowing wastewater into the water inlet holes by opening a guide groove on the inner wall of the sliding ring 31, while preventing the overflowing wastewater from flowing out irregularly and flowing back to the pipe well. The inner wall of the sliding ring 31 is provided with a guide groove, and the guide groove has a certain depth, which is intended to receive and guide the gradually overflowing wastewater.

[0045] To sum up, when the marking signal of the silt layer on the scale rod 22 moves up to the opening of the collection bucket 14, the scale rod 22 is fixed by the latch 23, and then the wastewater separation work is carried out. Before the wastewater overflows, it is necessary to first cancel the blocking of the water inlet by the blocking ring 33. At this time, the wedge block 3 is moved to drive the rotating ring 37 to rotate, so that the sliding ring 31 and the blocking ring 33 are linked, thereby realizing that the blocking ring 33 cancels the blocking of the water inlet. Then, the electric push rod 11 is started to drive the bottom plate 17 to move up and then drive the filter plate 18 to move up. The stratified wastewater layer and silt layer move up synchronously. In the process of the filter plate 18 moving up and not contacting the bottom of the scale rod 22, the wastewater will gradually overflow from the opening of the collection bucket 14. The overflowing wastewater will enter the water storage chamber of the collecting barrel 14 from the water inlet hole under the action of the guide groove on the inner wall of the sliding ring 31. When the filter plate 18 moves to contact the bottom of the scale rod 22, the stratified wastewater in the collecting barrel 14 has completely overflowed. At this time, the wedge block 3 is reversed, and under the action of the pressure spring 36, the sliding ring 31, the blocking ring 33 and the rotating ring 37 are all reset, and the blocking ring 33 resumes the blocking effect on the water inlet hole, thereby preventing other impurities from entering the water storage chamber of the collecting barrel 14 through the water inlet hole. In order to facilitate the discharge of the wastewater in the water storage chamber, the outer wall of the collecting barrel 14 is provided with a water outlet 15, and the wastewater can be discharged through the external pipe on the water outlet 15, which is convenient for subsequent recycling and reuse.

[0046] When the filter plate 18 moves to contact the bottom of the scale rod 22, it means that the wastewater layer has completely overflowed, and only the sludge layer is left in the collection barrel 14. At this time, in order to facilitate the collection of the sludge layer, it is necessary to open the winch on the support platform 16 to pull the collection barrel 14 to the ground. When the staff observes that the wastewater in the collection barrel 14 is completely discharged, the collection barrel 14 is driven to the ground by starting the winch on the support platform 16, and then the winch is closed, and the relevant personnel collect the sludge in the collection barrel 14 on the ground.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
