Description

Technical Field

[0001] The present invention relates to the technical field of water supply equipment, and in particular to an internal cleaning device for water supply equipment. Background Art

[0002] Water tanks are commonly used water supply and storage devices in people's production and life. They can store water when the water supply is sufficient, and provide people with emergency water during water outages or droughts. They can also be used as high-rise water supply transfer equipment. The layered setting reduces the requirements for water pump power, making it an economical and effective water storage device.

[0003] Patent publication number CN218223930U discloses a water tank internal cleaning device. The device features a water inlet pipe extending vertically downward from the outside of the water tank body through the center of the top of the water tank body to the inside bottom surface of the water tank body. Several rotating high-pressure nozzles are evenly distributed on the water inlet pipe from top to bottom within the water tank body. Two adjacent rotating high-pressure nozzles rotate in opposite directions. Each rotating high-pressure nozzle has several water spray outlets uniformly distributed around the circumference. Both the cross-sectional and longitudinal sections of the nozzles are isosceles trapezoidal. The bottom of the water tank body is connected to a water outlet pipe, and the water inlet pipe on the outside of the water tank body is connected to a high-pressure pump. Advantages of this device include: It can thoroughly clean the inside of the water tank without blind spots; the high-pressure rotary cleaning is thorough; the rotation speed is proportional to the water pressure, making operation simple and flexible; the high-pressure nozzle is simple in structure, compact in size, and easy to repair or replace; the device has low manufacturing and maintenance costs; and the stainless steel pipe wall and high-pressure rotating nozzle are durable and stable during operation.

[0004] The water tank cleaning devices currently on the market still have the following problems: after the water tank is cleaned, the outlet pipe is usually used to drain and remove impurities. However, when the water tank drains too much, scale and other debris mixed in the water often cause the outlet pipe to be blocked. Therefore, it is necessary to design a water tank cleaning device with a large flow drainage function. Summary of the Invention

[0005] The present invention proposes an internal cleaning device for water supply equipment, which solves the problem in the related art that after the water tank is cleaned, an outlet pipe is usually used to drain and remove impurities. However, when the water tank drains too much water, scale and other debris mixed in the water often cause the outlet pipe to be blocked.

[0006] The technical solution of the present invention is as follows: An internal cleaning device for water supply equipment includes a box body, and a drainage device, a scraping device, a mixing device and an adsorption device are arranged inside the box body; the drainage device includes a square box, a telescopic rod, a baffle and a plug, the square box is fixed at the bottom of the outer wall of the box body, the telescopic rod is fixed to the inner wall of the square box, the baffle is fixed to the telescopic end of the telescopic rod, and the plug is fixed on the inner side of the baffle. A square drain outlet is opened on the side of the bottom of the box body, and the plug penetrates and is slidably installed on the inner wall of the square drain outlet. After the scale and other impurities on the inner wall of the box body are cleaned, the telescopic rod is started, and the telescopic rod pushes the baffle outward, and the baffle drives the plug to move outward and open, so that the large-flow drain outlets on both sides of the box body are opened, thereby achieving the purpose of discharging the cleaned scale and avoiding the blockage of the water outlet after scale accumulation.

[0007] According to the above technical solution, the drainage device also includes a sealing plate and a long plate, a square groove is provided on the side surface of the bottom of the box body, the sealing plate is fixed on the inner side of the plug, the sealing plate is slidably installed in the square groove, a circular drain outlet is provided on the top surface of the sealing plate, the box body drain pipe is located on the movement trajectory of the sealing plate, and the top surface of the sealing plate is provided with a drainage groove, and the inner side of the long plate is hinged to the inner wall of the drainage groove. When the plug moves outward and opens, the plug drives the sealing plate to move outward, and the sealing plate is used to seal and intercept the water outlet to prevent a small amount of scale and other impurities from still falling into the water outlet. Long-term use and accumulation will still cause the pipe outlet to be blocked. At the same time, when the plug moves outward, the sealing plate drives the long plate to move outward, and the long plate opens the drainage groove downward. Because the plug blocks the drainage, it can only drain to the front and rear sides. Solid matter such as scale may be partially accumulated at the bottom of the plug. The long plate allows the solid to be discharged directly and achieves the purpose of increasing the drainage volume.

[0008] According to the above technical solution, the scraping device includes a telescopic rod 2, a connecting plate and a scraper. The telescopic rod 2 is fixed to the top surface of the inner wall of the box, the connecting plate is fixed to the middle of the telescopic end of the telescopic rod 2, and the inner wall of the scraper is fixed to the front and rear ends of the connecting plate. The scraper is slidably installed on the inner wall of the box. When the water tank needs to be cleaned, the telescopic rod 2 is started, the telescopic rod 2 drives the connecting plate to move up and down, and the connecting plate drives the scraper to move up and down. The scraper is used to scrape and clean the scale and impurities attached to the inner wall of the water tank, thereby achieving the purpose of automatically cleaning the water tank, which is convenient and fast, and saves time for manual cleaning.

[0009] According to the above technical solution, the scraping device also includes a square rod, a support rod and a push block. The square rod is fixed to the bottom of the scraper, the top of the support rod is hinged to the bottom of the square rod, the push block is hinged to the bottom end of the support rod, and the push block is slidably installed on the bottom surface of the inner wall of the box. The scraper drives the square rod to move up and down, the square rod pushes and pulls the support rod, and the support rod pushes and pulls the push block. The push block is used to push the scale that falls on the bottom to both sides, so that the solid matter can be discharged together when the plug is opened to drain water later, making the entire cleaning operation highly automated and more convenient.

[0010] According to the above technical solution, the mixing device includes a bracket, a cylinder, a propeller and a cylinder. The top of the bracket is fixed to the top surface of the inner wall of the box, the cylinder is rotatably installed at the bottom of the bracket, the propeller is fixed to the outer wall of the cylinder, and an arc-shaped groove is provided on the inner wall of the cylinder. One end of the cylinder is fixed to the bottom of the second telescopic rod, and the other end of the cylinder is slidably installed in the arc-shaped groove. When the second telescopic rod moves up and down, the second telescopic rod drives the cylinder to move up and down, and the cylinder passes through the arc-shaped groove inside the cylinder, thereby driving the cylinder to rotate back and forth, and the cylinder drives the propeller to rotate back and forth. When cleaning the inside of the water tank, some cleaning agent is often added. The stirring of the propeller makes the cleaning agent and the water in the water tank mix more evenly, accelerates the diffusion of the cleaning agent, and makes it easier for the scraper to scrape off scale.

[0011] According to the above technical solution, the mixing device also includes a bevel, a rebound plate and a knocking column. The bevel is fixed on the top of the cylinder, the rebound plate is fixed on both sides of the connecting plate by a spring, and the knocking column is fixed on the side of the rebound plate close to the connecting plate. The bevel is located on the movement trajectory of the rebound plate, and the connecting plate is located on the movement trajectory of the knocking column. When the connecting plate moves up and down, it drives the rebound plate to move up and down, and the rebound plate drives the knocking column to move up and down. When the rebound plate moves downward, it will be squeezed by the bevel, and the rebound plate will move away from the connecting plate. When the rebound plate moves upward, under the action of the spring force, the rebound plate rebounds toward the connecting plate, and the connecting plate drives the knocking column to rebound toward the connecting plate. The knocking column hits the connecting plate, causing the connecting plate and the scraper to vibrate. During the operation of the scraper, some impurities will adhere to it. The vibration can help some impurities adhered to the scraper to fall off, making the cleaning more thorough.

[0012] According to the above technical solution, the adsorption device includes a water inlet pipe, a collet and activated carbon. The water inlet pipe is fixed on the top surface of the box body, the collet is slidably installed on the inner wall of the water inlet pipe, and the activated carbon is clamped inside the collet. To clean the impurities in the water tank, it is more necessary to control the water quality at the source. A lot of microorganisms, bacteria and algae from the water supply source will enter the water inlet end of the water inlet pipe of the water tank. In order to prevent these microorganisms from breeding in the water tank, it will bring difficulties to the cleaning of the water tank and increase the workload of cleaning. Therefore, these microorganisms are intercepted and isolated by the activated carbon arranged inside the collet, so as to ensure the health of the water quality entering the water tank from the source. At the same time, the arrangement of the collet makes it more convenient to replace the activated carbon regularly, avoiding the failure of the activated carbon due to long-term use.

[0013] According to the above technical solution, the adsorption device also includes concentric rings, arc blocks, lifting rings and locking blocks. The concentric rings are fixed to the inner wall of the water inlet pipe, the arc blocks are fixed to the top of the funnel, the lifting rings are fixed to the inner wall of the funnel, and the locking blocks are fixed to the top surfaces of the concentric rings. Because the adsorption device is arranged at the water inlet end, the large water pressure and water flow impact may cause the funnel to shake and create a gap between it and the water inlet pipe, resulting in poor activated carbon interception effect. Therefore, when placing a new adsorption device, the lifting ring is twisted, and the lifting ring drives the funnel to rotate, and the funnel drives the arc blocks to rotate, and the arc blocks are stuck between the concentric rings and the locking blocks, thereby achieving the purpose of fixing the adsorption device and avoiding the generation of a movable gap between the funnel and the water inlet pipe. The reverse rotation can also make it easy to dismantle, and loading and unloading is convenient.

[0014] The working principle and beneficial effects of the present invention are:

[0015] 1. In the present invention, the drainage device is arranged so that the square box, telescopic rod 1, baffle and plug cooperate with each other, and the baffle drives the plug to move outward and open, so that the large-flow drainage outlets on both sides of the box are opened, thereby achieving the purpose of discharging the cleaned scale and preventing the scale from accumulating and clogging the outlet pipe; the sealing plate and the long plate cooperate with each other, and the plug drives the sealing plate to move outward, and the sealing plate is used to block and intercept the outlet pipe, so that a small amount of scale and other impurities will still fall into the outlet pipe, and the sealing plate drives the long plate to move outward, and the long plate opens the drainage groove downward so that the solids can be discharged directly and achieve the purpose of increasing the drainage volume.

In the present invention, the bracket, cylinder, propeller and cylinder are coordinated through the setting of the mixing device, and the telescopic rod 2 drives the cylinder to move up and down. The cylinder passes through the arc-shaped slide groove inside the cylinder, thereby driving the cylinder to rotate back and forth, and the cylinder drives the propeller to rotate back and forth. When cleaning the inside of the water tank, some cleaning agents are often added. The stirring of the propeller is used to make the cleaning agent and the water in the water tank mix more evenly, accelerate the diffusion of the cleaning agent, and make it easier for the scraper to scrape off scale; the inclined body, rebound plate and knocking column are coordinated. Under the action of the spring force, the rebound plate rebounds toward the connecting plate, and the connecting plate drives the knocking column to rebound toward the connecting plate.

[0029] Example 1

[0030] like Figures 1 to 4 As shown, this embodiment proposes an internal cleaning device for water supply equipment, including a box body 1, and a drainage device 2, a scraping device 3, a mixing device 4 and an adsorption device 5 are arranged inside the box body 1; the drainage device 2 includes a square box 21, a telescopic rod 22, a baffle 23 and a plug 24, the square box 21 is fixed to the bottom of the outer wall of the box body 1, and the telescopic rod 22 is fixed to the inner wall of the square box 21. After the scale and other impurities on the inner wall of the box body 1 are cleaned, the telescopic rod 22 is started, the baffle 23 is fixed to the telescopic end of the telescopic rod 22, the telescopic rod 22 pushes the baffle 23 outward, and the plug 24 is fixed on the inner side of the baffle 23. The baffle 23 drives the plug 24 to move outward and open, and a square drain outlet is opened on the bottom side of the box body 1. The plug 24 penetrates and is slidably installed on the inner wall of the square drain outlet, so that the large-flow drain outlets on both sides of the box body 1 are opened, thereby achieving the purpose of discharging the cleaned scale and avoiding clogging of the water outlet after scale accumulation.

[0031] When the plug 24 is moved outward, the sealing plate 25 drives the sealing plate 25 to move outward, and the sealing plate 25 is slidably installed in the square groove. The top surface of the sealing plate 25 is provided with a circular drain outlet, and the drain pipe of the box 1 is located on the movement trajectory of the sealing plate 25. The sealing plate 25 is used to block the outlet pipe to prevent a small amount of scale and other impurities from falling into the outlet pipe. Long-term use will still cause the pipe outlet to be blocked.

[0032] The scraping device 3 includes a second telescopic rod 31, a connecting plate 32 and a scraper 33. The second telescopic rod 31 is fixed to the top surface of the inner wall of the box body 1. When the water tank needs to be cleaned, the second telescopic rod 31 is started, and the connecting plate 32 is fixed to the middle of the telescopic end of the second telescopic rod 31. The second telescopic rod 31 drives the connecting plate 32 to move up and down. The inner wall of the scraper 33 is fixed to the front and rear ends of the connecting plate 32. The connecting plate 32 drives the scraper 33 to move up and down. The scraper 33 is slidably installed on the inner wall of the box body 1. The scraper 33 is used to scrape and clean the scale and impurities attached to the inner wall of the water tank, thereby achieving the purpose of automatically cleaning the water tank, which is convenient and fast and saves the time of manual cleaning.

[0033] The scraping device 3 also includes a square rod 34, a support rod 35 and a push block 36. The square rod 34 is fixed to the bottom of the scraper 33, and the scraper 33 drives the square rod 34 to move up and down. The top of the support rod 35 is hinged to the bottom of the square rod 34, and the square rod 34 pushes and pulls the support rod 35. The push block 36 is hinged to the bottom end of the support rod 35, and the support rod 35 pushes and pulls the push block 36. The push block 36 is slidably installed on the bottom surface of the inner wall of the box body 1. The push block 36 is used to push the scale fallen on the bottom to both sides, so that the solid matter can be discharged together when the plug 24 is opened to drain water, making the entire cleaning operation highly automated and more convenient.

[0034] When the plug 24 is moved outwards and opened, the plug 24 drives the sealing plate 25 to move outwards, and the sealing plate 25 is used to block the water outlet, so that a small amount of impurities such as scale still fall into the water outlet, which may be blocked by long-term use. At the same time, when the plug 24 is moved outwards, the sealing plate 25 drives the long plate 26 to move outwards, and the long plate 26 opens the drain groove downwards. Because the plug 24 blocks the drainage, the drainage can only be discharged to the front and rear sides. Solid matter such as scale may accumulate at the bottom of the plug 24. The long plate 26 allows the solid to be discharged directly and achieves the purpose of increasing the drainage volume.

[0035] When the water tank needs to be cleaned, the telescopic rod 31 is started, and the telescopic rod 31 drives the connecting plate 32 to move up and down, and the connecting plate 32 drives the scraper 33 to move up and down, and the scraper 33 is used to scrape and clean the scale and impurities attached to the inner wall of the water tank, thereby achieving the purpose of automatically cleaning the water tank, which is convenient and fast and saves time for manual cleaning; at the same time, the scraper 33 drives the square rod 34 to move up and down, the square rod 34 pushes and pulls the support rod 35, and the support rod 35 pushes and pulls the push block 36, and the push block 36 is used to push the scale fallen on the bottom to both sides, so that the solid matter can be discharged together when the plug 24 is opened to drain water, making the entire cleaning operation highly automated and more convenient.

[0036] Example 2

[0037] like Figures 5 to 7 As shown, based on the same concept as the above embodiment 1, this embodiment further proposes a mixing device 4 and an adsorption device 5.

[0038] The mixing device 4 includes a bracket 41, a cylinder 42, a propeller 43 and a cylinder 44. The top of the bracket 41 is fixed to the top surface of the inner wall of the box body 1, and the cylinder 42 is rotatably installed at the bottom of the bracket 41. An arc-shaped groove is provided on the inner wall of the cylinder 42. One end of the cylinder 44 is fixed to the bottom of the telescopic rod 2 31. When the telescopic rod 2 31 moves up and down, the telescopic rod 2 31 drives the cylinder 44 to move up and down. The other end of the cylinder 44 is slidably installed in the arc-shaped groove. The cylinder 44 passes through the arc-shaped groove inside the cylinder 42, thereby driving the cylinder 42 to rotate back and forth. The propeller 43 is fixed to the outer wall of the cylinder 42, and the cylinder 42 drives the propeller 43 to rotate back and forth. When cleaning the inside of the water tank, some cleaning agent is often added. The stirring of the propeller 43 makes the cleaning agent and the water in the water tank mix more evenly, accelerates the diffusion of the cleaning agent, and makes it easier for the scraper 33 to scrape off scale.

[0039] The mixing device 4 also includes a bevel 45, a rebound plate 46 and a knocking column 47. The bevel 45 is fixed to the top of the cylinder 42. The rebound plate 46 is fixed to both sides of the connecting plate 32 by a spring. When the connecting plate 32 moves up and down, the rebound plate 46 is driven to move up and down. The knocking column 47 is fixed to the side of the rebound plate 46 close to the connecting plate 32. The rebound plate 46 drives the knocking column 47 to move up and down. The bevel 45 is located on the movement trajectory of the rebound plate 46. When the rebound plate 46 moves downward, it will be squeezed by the bevel 45 and rebound. The plate 46 is away from the connecting plate 32. When the rebound plate 46 moves upward, under the action of the spring force, the rebound plate 46 rebounds toward the connecting plate 32. The connecting plate 32 is located on the movement trajectory of the knocking column 47. The connecting plate 32 drives the knocking column 47 to rebound toward the connecting plate 32. The knocking column 47 hits the connecting plate 32, causing the connecting plate 32 and the scraper 33 to vibrate. During the operation of the scraper 33, some impurities will adhere to it. The vibration can help some of the impurities adhered to the scraper 33 to fall off, making the cleaning more thorough.

[0040] The adsorption device 5 includes a water inlet pipe 51, a funnel 52 and activated carbon 53. The water inlet pipe 51 is fixed on the top surface of the box body 1, the funnel 52 is slidably installed on the inner wall of the water inlet pipe 51, and the activated carbon 53 is clamped inside the funnel 52. To clean the impurities in the water tank, it is more necessary to control the water quality at the source. A lot of microorganisms, bacteria and algae from the water supply source will enter the water inlet end of the water inlet pipe 51 of the water tank. In order to prevent these microorganisms from breeding in the water tank, which will bring difficulties to the cleaning of the water tank and increase the workload of cleaning, these microorganisms are intercepted and isolated by the activated carbon 53 arranged inside the funnel 52, so as to ensure the health of the water quality entering the water tank from the source. At the same time, the arrangement of the funnel 52 makes it more convenient to replace the activated carbon 53 regularly, thereby avoiding the failure of the activated carbon 53 due to long-term use.

[0041] The adsorption device 5 also includes a concentric ring 54, an arc block 55, a lifting ring 56 and a locking block 57. The concentric ring 54 is fixed to the inner wall of the water inlet pipe 51, the arc block 55 is fixed to the top of the funnel 52, and the lifting ring 56 is fixed to the inner wall of the funnel 52. Because the adsorption device 5 is arranged at the water inlet end, the large water pressure and water flow impact may cause the funnel 52 to shake and form a gap between it and the water inlet pipe 51, resulting in poor interception effect of the activated carbon 53. Therefore, when placing a new adsorption device 5, the lifting ring 56 is twisted, and the locking block 57 is fixed to the top surface of the concentric ring 54. The lifting ring 56 drives the funnel 52 to rotate, and the funnel 52 drives the arc block 55 to rotate. The arc block 55 is stuck between the concentric ring 54 and the locking block 57, thereby achieving the purpose of fixing the adsorption device 5, avoiding the generation of a movable gap between the funnel 52 and the water inlet pipe 51, and the reverse rotation can also be easily dismantled, and the loading and unloading is convenient.

[0042] In this embodiment, when in use, when the telescopic rod 31 moves up and down, the telescopic rod 31 drives the cylinder 44 to move up and down, and the cylinder 44 passes through the arc-shaped slide groove inside the cylinder 42, thereby driving the cylinder 42 to rotate back and forth, and the cylinder 42 drives the propeller 43 to rotate back and forth. When cleaning the inside of the water tank, some cleaning agent is often added. The stirring of the propeller 43 makes the cleaning agent and the water in the water tank mix more evenly, accelerates the diffusion of the cleaning agent, and makes it easier for the scraper 33 to scrape off scale; at the same time, when the connecting plate 32 moves up and down, it drives the rebound plate 46 to move up and down, and the rebound plate 46 moves up and down. The plate 46 drives the knocking column 47 to move up and down. The rebound plate 46 will be squeezed by the inclined surface 45 when it moves downward, and the rebound plate 46 will move away from the connecting plate 32. When the rebound plate 46 moves upward, under the action of the spring force, the rebound plate 46 rebounds toward the connecting plate 32, and the connecting plate 32 drives the knocking column 47 to rebound toward the connecting plate 32. The knocking column 47 hits the connecting plate 32, causing the connecting plate 32 and the scraper 33 to vibrate. During the operation of the scraper 33, some impurities will adhere to it. The vibration can help some of the impurities adhered to the scraper 33 to fall off, making the cleaning more thorough.

[0043] For cleaning impurities in the water tank, it is more necessary to control the water quality at the source. Many microorganisms, bacteria and algae from the water supply source will enter the water inlet end of the water inlet pipe 51 of the water tank. In order to prevent these microorganisms from breeding in the water tank, which will bring difficulties to the cleaning of the water tank and increase the workload of cleaning, the activated carbon 53 set inside the collet 52 is used to intercept and isolate these microorganisms, thereby ensuring the health of the water entering the water tank from the source. At the same time, the setting of the collet 52 makes it more convenient to replace the activated carbon 53 regularly, thereby avoiding the failure of the activated carbon 53 due to long-term use. Because the adsorption device 5 is arranged at the water inlet end, the large water pressure and water flow impact may cause the funnel 52 to shake and form a gap between it and the water inlet pipe 51, resulting in poor interception effect of the activated carbon 53. Therefore, when placing a new adsorption device 5, the lifting ring 56 is twisted, and the lifting ring 56 drives the funnel 52 to rotate, and the funnel 52 drives the arc block 55 to rotate, and the arc block 55 is stuck between the concentric ring 54 and the locking block 57, thereby achieving the purpose of fixing the adsorption device 5, avoiding the generation of a movable gap between the funnel 52 and the water inlet pipe 51, and the funnel 52 can also be easily removed by reverse rotation, and it is convenient to load and unload.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
