Description

Technical Field

[0001] This utility model relates to the field of water tank cleaning technology, specifically to a water tank cleaning device for secondary water supply. Background Technology

[0002] Secondary water supply refers to the process by which units or individuals store and pressurize urban public water supply or self-built water supply facilities, and then supply them to users or for their own use through pipelines. Secondary water supply is mainly established to compensate for the lack of pressure in municipal water supply pipelines and to ensure water supply for people living in high-rise buildings. Whether secondary water supply facilities are constructed and designed in accordance with regulations and the quality of construction directly affect the water quality, water pressure, and water supply safety of secondary water supply, which is closely related to the normal and stable life of the people. Compared with raw water supply, the water quality of secondary water supply is more easily polluted. Therefore, dirt and impurities often accumulate inside secondary water supply equipment, so it is necessary to clean it regularly to ensure the safety of secondary water supply.

[0003] For example, Chinese Patent (CN221095306U) discloses a cleaning device for the interior of a secondary water supply tank, relating to the field of secondary water supply technology. This cleaning device includes an electric telescopic rod, with a hollow rod fixedly connected to its outer wall. A square rod is slidably connected to the inner wall of the hollow rod, and a brush is fixedly connected to the outer wall of the square rod. A connecting rod is hinged to the outer wall of the electric telescopic rod, and the outer wall of the connecting rod is hinged to the outer wall of the brush. This invention, by incorporating a motor reducer, an electric telescopic rod, a brush, and a connecting rod, allows the electric telescopic rod to rotate when the motor reducer is activated. Simultaneously, the connecting rod rotates to clean the inner wall of the secondary water supply tank. Activating the electric telescopic rod moves the connecting rod, causing the brush to move laterally, thus adjusting the cleaning force on the inner wall of the secondary water supply tank, improving the cleaning efficiency and effectiveness.

[0004] The aforementioned device places all cleaning components inside the secondary water supply tank, along with the connecting rod and electric telescopic rod, which are also fixedly installed inside the tank. The tank only needs to be cleaned periodically. However, the cleaning device, located inside the secondary water supply tank, is prone to accumulating dirt and grime. In the enclosed and humid environment inside the tank, bacteria and mold can easily grow. If the cleaning device is not cleaned regularly, it may become a source of pollution, which is detrimental to the overall cleanliness of the tank. To address these issues, a cleaning device for secondary water supply tanks is proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a water tank cleaning device for secondary water supply. It solves the problem that in the current method, all cleaning components are located inside the secondary water supply tank, and the connecting rod and electric telescopic rod connected to it are also fixed inside the secondary water supply tank. The water tank only needs to be cleaned once a period of time. However, if the cleaning device is located inside the secondary water supply tank, it is easy for dirt and grime to accumulate inside the tank. In the closed and humid environment inside the water tank, bacteria and mold can easily grow. If the cleaning device is not cleaned regularly, it may become a source of pollution, which is not conducive to the overall cleanliness of the water tank.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a water tank cleaning device for secondary water supply, comprising a water tank, wherein a cleaning component is detachably connected inside the water tank;

[0007] The cleaning component includes a fixing ring, which is located above the water tank. Fixing plates are fixedly connected to both sides of the fixing ring. Threaded rods are threadedly connected to the bottom of both fixing plates via threaded sleeves. A clamping block is rotatably connected to one end of each threaded rod near the side wall of the water tank via a rotating seat. A handwheel is fixedly connected to the other end of each threaded rod away from the clamping block.

[0008] Preferably, an annular limiting groove is formed in the middle of the upper surface of the fixed ring, a toothed ring is fixedly connected to the inner side of the fixed ring, a rotating bar is provided above the fixed ring, and limiting blocks are fixedly connected to the left and right ends of the bottom of the rotating bar. The two limiting blocks are slidably connected inside the limiting groove, and at least three balls are rotatably connected to the bottom of the two limiting blocks. The bottom of the limiting blocks is rolledly connected to the bottom surface inside the limiting groove through the balls.

[0009] Preferably, the bottom left and right ends of the rotating bar are rotatably connected to rotating gears on the inner side of the toothed ring, both rotating gears mesh with the inner side of the toothed ring, and a cleaning roller brush is fixedly connected below each of the two rotating gears, with the bristles of the cleaning roller brush abutting against the inner wall of the water tank.

[0010] Preferably, a galvanized water pipe is fixedly connected to the middle of the rotating bar, a connecting bar is fixedly connected to the bottom of the galvanized water pipe, and several water spray holes are opened through the outer surface of the galvanized water pipe. The bottoms of the two cleaning rollers are rotatably connected to the top of the connecting bar via a rotating shaft, and a support base is rotatably connected to the middle position of the bottom of the connecting bar.

[0011] Preferably, a support frame is provided above the rotating bar, and at least two support bars are fixedly connected to the bottom of both the front and rear sides of the support frame, and the support bars are fixedly connected to the side of the fixed ring.

[0012] Preferably, the galvanized water pipe is rotatably connected to the support frame above and the inlet pipe via a connector. The galvanized water pipe, the connector, and the inlet pipe are interconnected. A driven gear is fixedly connected to the outer surface of the galvanized water pipe above the rotating bar.

[0013] Preferably, a servo motor is fixedly connected to the right side of the upper surface of the support frame, and the output end of the servo motor passes through the upper surface of the support frame and is fixedly connected to a drive gear, which meshes with the driven gear.

[0014] Compared with the prior art, the advantages of this utility model are:

[0015] 1. This utility model makes the cleaning components and water tank detachable, so that the whole unit can be taken out of the water tank after the cleaning operation is completed. It does not need to be placed in the closed and humid water tank for a long time, which reduces the risk of dirt and bacteria breeding in the cleaning device itself. It solves the problem of traditional fixed installation cleaning devices becoming a source of pollution. Through the cooperation of threaded rod and clamping block, the cleaning components and water tank can be quickly fixed or disassembled. The operation is convenient and facilitates the cleaning and maintenance of the cleaning device itself.

[0016] 2. The cleaning roller brush of this utility model comes into close contact with the inner wall of the water tank during rotation. Combined with the water flow sprayed from the galvanized water pipe, it achieves dual cleaning of "brushing + rinsing", which can effectively remove dirt and impurities from the inner wall of the water tank. The rotating bar drives the cleaning roller brush to move circumferentially along the inner wall of the water tank. At the same time, the rotating gear meshes with the toothed ring to make the roller brush rotate itself, forming a compound cleaning action to ensure that all areas of the inner wall of the water tank can be thoroughly cleaned without any dead corners.

[0027] In the description of this utility model, it should be noted that the terms "front", "up", "down", "left", "right", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0029] Reference Figure 1 - Figure 8 As shown, a water tank cleaning device for secondary water supply includes a water tank 1, a cleaning component 2 detachably connected inside the water tank 1, and a drain port (not shown) at the lowest point of the bottom of the water tank 1 for discharging the dirt cleaned by the cleaning component 2.

[0030] The cleaning component 2 includes a fixing ring 201, which is positioned above the water tank 1. Fixing plates 219 are fixedly connected to both sides of the fixing ring 201. Threaded rods 220 are threadedly connected to the bottom of each fixing plate 219 via threaded sleeves. Clamping blocks 222 are rotatably connected to the ends of the two threaded rods 220 near the side wall of the water tank 1 via rotating seats. Handwheels 221 are fixedly connected to the other ends of the two threaded rods 220 away from the clamping blocks 222. By rotating the handwheels 221, the contact pressure between the clamping blocks 222 and the outer wall of the water tank 1 can be precisely adjusted to adapt to different thicknesses of the water tank 1 wall, ensuring stability and preventing shaking during cleaning.

[0031] Furthermore, an annular limiting groove 202 is provided in the middle of the upper surface of the fixed ring 201. A toothed ring 206 is fixedly connected to the inner side of the fixed ring 201. A rotating bar 203 is provided above the fixed ring 201. Limiting blocks 204 are fixedly connected to the left and right ends of the bottom of the rotating bar 203. Both limiting blocks 204 are slidably connected inside the limiting groove 202. At least three balls 205 are rotatably connected to the bottom of both limiting blocks 204. The bottom of the limiting blocks 204 is rolled and connected to the bottom surface inside the limiting groove 202 through the balls 205. The rolling of the balls 205 reduces frictional resistance. The sliding of the limiting blocks 204 along the limiting groove 202 ensures that the rotation trajectory of the rotating bar 203 is accurate, avoids deviation, and improves the fit between the cleaning roller brush 208 and the inner wall of the water tank 1.

[0032] Furthermore, at both ends of the bottom of the rotating bar 203, rotating gears 207 are rotatably connected to the inner side of the toothed ring 206. Both rotating gears 207 mesh with the inner side of the toothed ring 206. Cleaning roller brushes 208 are fixedly connected below the two rotating gears 207. The bristles of the cleaning roller brushes 208 abut against the inner wall of the water tank 1. The bristles of the cleaning roller brushes 208 are made of flexible material with a certain degree of elasticity to ensure that the bristles can fit tightly against the inner wall of the water tank 1. FDA-certified nylon 612 (PA612) or stainless steel wire can be selected. The bristle length is 20-30mm and the bristle hardness is 75-85 Shore A (moderate softness and hardness, balancing cleaning power and protection of the inner wall of the water tank).

[0033] Furthermore, a galvanized water pipe 209 is fixedly connected to the middle of the rotating bar 203, and a connecting bar 211 is fixedly connected to the bottom of the galvanized water pipe 209. Several water spray holes 210 are opened through the outer surface of the galvanized water pipe 209. The bottoms of the two cleaning roller brushes 208 are rotatably connected to the top of the connecting bar 211 via a rotating shaft. A support base 212 is rotatably connected to the middle of the bottom of the connecting bar 211. The support base 212 contacts the bottom of the water tank 1 to form a three-point support to prevent the cleaning component 2 from tilting. The connecting bar 211 serves as the base of the rotating shaft to ensure the verticality of the cleaning roller brushes 208 and avoid uneven wear of the bristles. The water spray holes 210 are evenly distributed to form a high-pressure water curtain, which softens the dirt and washes away impurities, reducing secondary pollution.

[0034] Furthermore, a support frame 216 is provided above the rotating bar 203. At least two support bars 223 are fixedly connected to the bottom of the front and rear sides of the support frame 216. The support bars 223 are fixedly connected to the side of the fixing ring 201.

[0035] Furthermore, the galvanized water pipe 209 passes through the support frame 216 and is rotatably connected to the inlet pipe 215 via the connector 214. The galvanized water pipe 209, the connector 214, and the inlet pipe 215 are interconnected. The outer surface of the galvanized water pipe 209 is fixedly connected to the driven gear 213 above the rotating bar 203. The galvanized water pipe 209 is a rigid water pipe to prevent deformation. The rotary connector 214 allows the galvanized water pipe 209 to rotate freely while maintaining a high-pressure water seal (pressure resistance ≥1MPa) to prevent water leakage from affecting the cleaning effect.

[0036] Furthermore, a servo motor 217 is fixedly connected to the right side of the upper surface of the support frame 216. The output end of the servo motor 217 passes through the upper surface of the support frame 216 and is fixedly connected to a drive gear 218. The drive gear 218 meshes with the driven gear 213. The transmission ratio between the drive gear 218 and the driven gear 213 is 1:2, which reduces the load on the servo motor 217, increases the torque output, and ensures stable rotation.

[0037] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer for control. The detailed description of known functions and components is omitted in the specific implementation of this disclosure. To ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0038] Working principle: Place the cleaning component 2 into the water tank 1, so that the fixing ring 201 is placed on the top edge of the water tank 1, ensuring that the cleaning roller brush 208 is in close contact with the inner wall of the water tank 1. Rotate the handwheel 221 under the fixing plates 219 on both sides, which drives the threaded rod 220 to move along the threaded sleeve towards the side wall of the water tank 1. The clamping block 222 at the end of the threaded rod 220 moves along with it until the clamping block 222 is in close contact with the outer wall of the water tank 1, thus firmly fixing the cleaning component 2 to the water tank 1. Connect the water inlet pipe 215 to the external water source, and the water flows through the water inlet pipe in sequence. Pipe 215 and connector 214 enter the galvanized water pipe 209 and spray water from the spray hole 210 on the surface of the galvanized water pipe 209 to pre-wet the inner wall of the water tank 1 and soften the dirt. Check whether the support base 212 is in contact with the bottom of the water tank 1 to ensure that the connecting strip 211 and the cleaning roller brush 208 are in a stable state. The ball 205 at the bottom of the limit block 204 should roll flexibly in the limit groove 202 to ensure that the rotating strip 203 can rotate smoothly. Start the servo motor 217 on the support frame 216, and its output end drives the drive gear 218. When the rotating bar 203 rotates, the driving gear 218 meshes with the driven gear 213 on the galvanized water pipe 209, thereby driving the galvanized water pipe 209 and the rotating bar 203 to rotate synchronously. When the rotating bar 203 rotates, the bottom limiting block 204 slides along the limiting groove 202 of the fixed ring 201, and the ball bearing 205 reduces friction to ensure smooth rotation. At the same time, the rotating gear 207 at the bottom of the rotating bar 203 meshes with the toothed ring 206 on the inner side of the fixed ring 201. As the rotating bar 203 rotates in a circular motion, the rotating gear 207 itself rotates, driving the rotating bar 203 to rotate. The cleaning roller brush 208 rotates and moves along the circumference of the inner wall of the water tank 1 while rotating, thus scrubbing the inner wall. The galvanized water pipe 209 rotates with the rotating bar 203, and the water jet from the spray hole 210 evenly washes the inner wall of the water tank 1 and the roller brush, dispersing the loose dirt and letting it sink to the bottom of the water tank 1 with the water flow, thus achieving thorough cleaning. After the cleaning operation is completed, the servo motor 217 and the water source are turned off, and the handwheel 221 is turned in the opposite direction to make the clamping block 222 disengage from the outer wall of the water tank 1, and the cleaning component 2 is removed from the water tank 1.
