Description

Technical Field

[0001] This application relates to the field of open drainage water collection and pumping technology, and in particular to a mobile open drainage water collection and pumping device. Background Technology

[0002] The published patent with authorization announcement number CN215822420U discloses a mobile open-drain water collection and pumping device, including a side frame, a base frame, an inner wire mesh, an outer wire mesh, a lifting ring, and a backwash pipe. The bottom of the side frame is fixedly connected to the base frame, and a lifting ring is fixedly connected to the top of the side frame. The side frame and the base frame are welded from seamless steel pipes to form a frame structure. The inner wire mesh is fixedly connected inside the frame structure, and the outer wire mesh is fixedly connected outside. Filter material is filled between the inner and outer wire meshes. A backwash pipe is connected in the middle of the frame structure. The backwash pipe has spray holes and a drain valve is connected to the bottom of the backwash pipe. The advantages are: convenient construction and installation, replacement of filter material, multiple reuses of the mobile open-drain water collection and pumping device, improved construction efficiency, and reduced production and maintenance costs.

[0003] The movable open-drain water collection and pumping device in the aforementioned patent, when the filter media becomes clogged, hoists the frame structure to a flat ground, connects the pressurized water pipe to the connection port at the top of the backwash pipe, and pressurizes the water in. First, the lower drain valve is opened to flush out the debris from the pipe, then the drain valve is closed, and pressurized water continues to be injected into the backwash pipe. Pressurized water is sprayed through the spray nozzles to flush the filter media until the debris inside the filter media is cleaned. However, because the frame structure is submerged in water for a long time, the silt and debris that settle in the water make the filter media located below the frame structure more difficult to clean than the filter media above. Therefore, it is necessary to focus on cleaning each section of the filter media. However, the aforementioned patent only uses high-pressure water jets from the spray nozzles for cleaning. Because the nozzles are large, the water jets are easily diffused, resulting in an unsatisfactory cleaning effect, which affects the subsequent use of the device and accelerates its service life.

[0004] Therefore, this application proposes a mobile open-drainage water collection and pumping device. Utility Model Content

[0005] This application proposes a mobile open-drainage water collection and pumping device to solve the problems mentioned in the background art. By arranging three sets of water spray holes on the backwash pipe and multiple sets of high-pressure nozzles at the top, middle and bottom of the backwash pipe, the device can precisely and intensively clean each section of the filter media. Since the bottom of the filter media is submerged in water for a long time, it is easy to accumulate silt and debris. By adding more high-pressure nozzles to each layer, the high-pressure nozzles can directly spray water from the water spray holes, which can enhance the water output force. Therefore, the cleaning force and cleaning range can be increased, greatly improving the practicality of the device.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] A portable open-drainage water collection and pumping device includes a side frame, a base frame, lifting rings, an outer wire mesh, an inner wire mesh, and a backwashing pipe. The bottom of the side frame is fixedly connected to the base frame, and the top of the side frame is fixedly connected to the lifting ring. The side frame and the base frame are welded from seamless steel pipes to form a frame structure. The inner wire mesh is fixedly connected inside the frame structure, and the outer wire mesh is fixedly connected outside the frame structure. Filter media is filled between the inner and outer wire meshes.

[0008] In a preferred embodiment, a backwash pipe is provided in the middle of the frame structure, the backwash pipe has three sets of water spray holes, and a connection port is provided at the top of the backwash pipe;

[0009] By connecting the pressurized water pipe to the connection port at the top of the backwash pipe, pressurized water is injected. First, the drain valve at the bottom is opened to flush out the debris in the pipe. After cleaning, the drain valve is closed, and pressurized water is injected into the backwash pipe, thereby improving the practicality of the device.

[0010] In a preferred embodiment, each group of spray holes has three layers: the group of spray holes above the backwash pipe has three spray holes per layer, the group of spray holes in the middle of the backwash pipe has five spray holes per layer, and the group of spray holes below the backwash pipe has seven spray holes per layer. The diameter of the upper spray holes is larger than that of the middle spray holes, and the diameter of the middle spray holes is larger than that of the lower spray holes.

[0011] By arranging three sets of water spray holes on the backwash pipe and multiple sets of high-pressure nozzles at the top, middle and bottom of the backwash pipe, the filter media can be precisely cleaned in a focused manner. Since the bottom of the filter media is submerged in water for a long time, it is easy for silt and debris to accumulate. By adding more high-pressure nozzles to each layer, the high-pressure nozzles can spray water directly from the water spray holes, which can enhance the water output force, thereby increasing the cleaning intensity and cleaning range, and thus improving the practicality of the device.

[0012] In a preferred embodiment, each of the water spray holes is equipped with a high-pressure nozzle, which includes a mounting component, a nozzle, a ring body, and a ring groove. Each nozzle is installed inside the mounting component and is mounted on the water spray hole via the mounting component.

[0013] Water is supplied to the high-pressure nozzle through the spray hole and sprayed through the nozzle to rinse the filter media until the impurities inside the filter media are washed away, thereby improving the practicality of the device.

[0014] In a preferred embodiment, each of the mounting components has an annular groove inside, and each of the nozzles is fixedly connected to a ring body outside the annular groove, and each nozzle is movably connected to the mounting component through the ring body and the annular groove.

[0015] During the high-pressure water jet process, the pressure causes the nozzle to rotate or turn within the mounting component through the ring and annular groove. This expands the cleaning range and increases the cleaning intensity of the high-pressure nozzle during the cleaning process, thereby enhancing the practicality of the device.

[0016] In a preferred embodiment, a sealing sleeve is fixedly connected to the outside of each nozzle, and each sealing sleeve is disposed at the connection between the nozzle and the mounting component;

[0017] By installing a sealing sleeve between the mounting component and the nozzle, the sealing sleeve is made of rubber and has a certain degree of elasticity, which improves the sealing performance of the nozzle during operation, thereby enhancing the practicality of the device.

[0018] In a preferred embodiment, a drain valve is fixedly connected to the bottom of the backwash pipe, and a leakage protection structure is fixedly connected to the side frame.

[0019] By incorporating a leakage protection structure, if a leakage occurs during operation and the frame structure becomes energized, the leakage protection device will trip and cut off the power supply when a person touches the frame, ensuring personal safety and thus improving the practicality of the device.

[0020] In a preferred embodiment, both the upper and lower sections of the backwash pipe are connected to float switches, which include an upper float switch and a lower float switch.

[0021] By setting up a lower float switch and an upper float switch, if the lower float switch fails, when the water level in the collection well rises to the level of the upper float switch (which triggers the emergency start failure alarm), the switch will automatically activate and power on the sewage pump, allowing the pump to operate and pump water, thus improving the practicality of the device.

[0022] The beneficial effects of this application are:

[0023] 1. This mobile open-drain water collection and pumping device, by arranging three sets of water spray holes on the backwash pipe and multiple sets of high-pressure nozzles at the top, middle and bottom of the backwash pipe, can precisely clean each section of the filter media. Since the bottom of the filter media is submerged in water for a long time, it is easy to accumulate silt and debris. By adding more high-pressure nozzles to each layer, the high-pressure nozzles can spray water directly from the water spray holes, which can enhance the water output force, thereby increasing the cleaning force and cleaning range, and greatly improving the practicality of the device.

[0024] 2. This movable open-drain water collection and pumping device, during the high-pressure water jetting process, causes the nozzle to rotate or turn within the mounting component through the ring body and ring groove under pressure. This expands the cleaning range and increases the cleaning intensity of the high-pressure nozzle during the cleaning process. By setting a sealing sleeve between the mounting component and the nozzle, the sealing sleeve is made of rubber material with a certain degree of elasticity, which is used to improve the sealing performance of the nozzle during operation, greatly enhancing the practicality of the device.

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0030] Reference Figure 1-3 A movable open-drainage water collection and pumping device includes a side frame 1, a base frame 2, a lifting ring 3, an outer wire mesh 4, an inner wire mesh 5, and a backwash pipe 9. The bottom of the side frame 1 is fixedly connected to the base frame 2, and the top of the side frame 1 is fixedly connected to the lifting ring 3. The side frame 1 and the base frame 2 are welded from seamless steel pipes to form a frame structure 211, wherein the inner wire mesh 5 is fixedly connected inside the frame structure 211, the outer wire mesh 4 is fixedly connected outside the frame structure 211, and filter material 6 is filled between the inner wire mesh 5 and the outer wire mesh 4.

[0031] A backwash pipe 9 is provided in the middle of the frame structure 211. Three sets of water spray holes 10 are opened on the backwash pipe 9, and a connection port 11 is provided at the top of the backwash pipe 9. Pressurized water is injected by connecting to the connection port 11 at the top of the backwash pipe 9 through a pressurized water pipe. First, the lower drain valve 12 is opened to flush out the debris in the pipe. After it is clean, the drain valve 12 is closed and pressurized water is injected into the backwash pipe 9, thereby improving the practicality of the device.

[0032] Each set of spray holes 10 has three layers. The set of spray holes 10 above the backwash pipe 9 has three spray holes per layer, the set of spray holes 10 in the middle of the backwash pipe 9 has five spray holes per layer, and the set of spray holes 10 below the backwash pipe 9 has seven spray holes per layer. The diameter of the upper spray holes 10 is larger than that of the middle spray holes 10, and the diameter of the middle spray holes 10 is larger than that of the lower spray holes 10. By arranging three sets of spray holes 10 on the backwash pipe 9 and multiple sets of high-pressure nozzles 101 at the top, middle, and bottom of the backwash pipe 9, the filter media 6 can be precisely and intensively cleaned. Since the bottom of the filter media 6 is submerged in water for a long time, it is easy to accumulate silt and debris. By adding more high-pressure nozzles 101 to each layer, the high-pressure nozzles 101 can directly spray water from the spray holes 10, which can enhance the water output force, thereby increasing the cleaning force and cleaning range, and thus improving the practicality of the device.

[0033] Each water spray hole 10 is equipped with a high-pressure nozzle 101. The high-pressure nozzle 101 includes a mounting component 1011, a nozzle 1012, a ring body 1013, and an annular groove 1014. Each nozzle 1012 is installed inside the mounting component 1011 and is mounted on the water spray hole 10 through the mounting component 1011. Water is delivered to the high-pressure nozzle 101 through the water spray hole 10 and sprayed with pressurized water through the nozzle 1012 to rinse the filter media 6 until the impurities in the filter media 6 are rinsed clean, thereby improving the practicality of the device.

[0034] Each mounting component 1011 has an annular groove 1014 inside. Each nozzle 1012 is fixedly connected to an annular body 1013 outside the annular groove 1014. Each nozzle 1012 is movably connected to the mounting component 1011 through the annular body 1013 and the annular groove 1014. During the high-pressure water jetting process, the pressure causes the nozzle 1012 to rotate or turn within the mounting component 1011 through the annular body 1013 and the annular groove 1014. This allows the high-pressure nozzle 101 to expand the cleaning range and increase the cleaning intensity during the cleaning process, thereby improving the practicality of the device.

[0035] Each nozzle 1012 is fixedly connected to a sealing sleeve 1015, and each sealing sleeve 1015 is located at the connection between the nozzle 1012 and the mounting component 1011. By setting a sealing sleeve 1015 between the mounting component 1011 and the nozzle 1012, the sealing sleeve 1015 is made of rubber and has a certain elasticity, which is used to improve the sealing performance of the nozzle 1012 during operation, thereby improving the practicality of the device.

[0036] A drain valve 12 is fixedly connected to the bottom of the backwash pipe 9, and a leakage protection structure 13 is fixedly connected to the side frame 1. By setting the leakage protection structure 13, if leakage occurs during operation, the frame structure 211 will be energized. When a person touches the frame, the leakage protector will cut off the power supply to ensure personal safety, thereby improving the practicality of the device.

[0037] Both the upper and lower sections of the backwash pipe 9 are connected to float switches, which include an upper float switch 8 and a lower float switch 7. By setting the lower float switch 7 and the upper float switch 8, if the lower float switch 7 fails, when the water level in the collection well rises to the level of the upper float switch 8 (the emergency start failure alarm level in the upper section), the switch will automatically connect the power supply to the sewage pump, and the sewage pump will start pumping water, thereby improving the practicality of the device.

[0038] Working principle: The device is hoisted into the sump and installed stably. A sewage pump is placed inside the frame structure 211 and connected to the power cable. This ensures that water from the drainage ditch flows normally into the sump. When the water level in the sump rises to the level of the lower float switch 7 (approximately 1.1m above the water level in the sump), the float rises horizontally. At this point, the switch activates, connecting the sewage pump to the power supply, and the sewage pump begins pumping water. If the lower float switch 7 malfunctions, and the water level in the collection well rises to the level of the upper float switch 8 (emergency start alarm level), the switch will automatically activate the sewage pump power supply, and the sewage pump will start pumping water. Simultaneously, the alarm will also activate and sound, alerting maintenance personnel to repair the pump. As the sewage pump pumps water, when the water level in the collection well drops to the level of the lower float switch 7, the switch will automatically deactivate and stop pumping. When the filter media 6 becomes clogged, the frame structure 211 will be hoisted to a flat area on the ground. The pressurized water pipe will be connected to the connection port 11 at the top of the backwash pipe 9 for pressurized water injection. First, open the lower drain valve 12 to flush out debris from the pipe. After cleaning, close the drain valve 12 and continue pressurizing water injection into the backwash pipe 9. Water will be delivered through the spray holes 10 to the high-pressure nozzle 101 and sprayed through the nozzles 1012 to flush the filter media 6 until all debris is washed away.

[0039] By arranging three sets of water spray holes 10 on the backwash pipe 9, and multiple sets of high-pressure nozzles 101 at the top, middle and bottom of the backwash pipe 9, the filter media 6 can be precisely cleaned in various sections. Since the bottom of the filter media 6 is submerged in water for a long time, it is easy to accumulate silt and debris. By adding more high-pressure nozzles 101 to each layer, the high-pressure nozzles 101 can directly spray water from the water spray holes 10, thereby increasing the water output force and thus increasing the cleaning intensity and cleaning range.

[0040] During the high-pressure water jetting process, the pressure causes the nozzle 1012 to rotate or turn within the mounting component 1011 through the ring body 1013 and the annular groove 1014. This allows the high-pressure nozzle 101 to expand the cleaning range and increase the cleaning intensity during the cleaning process. A sealing sleeve 1015 is provided between the mounting component 1011 and the nozzle 1012. The sealing sleeve 1015 is made of rubber and has a certain degree of elasticity, which is used to improve the sealing performance of the nozzle 1012 during operation.

[0041] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and the inventive concept of this application, should be included within the scope of protection of this application.
