Description

Technical Field

[0001] This utility model relates to the field of water supply equipment technology, specifically to an outdoor direct-connection intelligent variable frequency secondary water supply equipment. Background Technology

[0002] If the hygiene of water storage and supply is not perfect, it is very easy to cause secondary pollution of water quality. The water in the secondary water supply equipment usually contains a certain concentration of residual chlorine. A small amount of residual chlorine will not have a negative impact on the human body, but can play a role in sterilization and disinfection. However, the sterilization and disinfection operation of the existing secondary water supply equipment is prone to interference with the negative pressure water supply equipment. In addition, the effectiveness of the water quality detection function of the current secondary water supply equipment needs to be improved.

[0003] To address the aforementioned technical issues, Chinese Patent No. CN113898035B discloses a smart urban water supply device with water quality detection capabilities. The device includes a three-way valve A and a three-way valve C. A water inlet pipe is fixedly connected to the rear end of the three-way valve A. A three-way valve B is connected to the bottom end of the tank. A three-way valve D is fixedly connected to the top end of the mounting pipe. A water pump A is fixedly connected to the front end of the three-way valve C. A water pressure sensor is installed at the top of the outlet pipe. The water pump B is connected to two three-way valves E. A residual chlorine sensor is installed in the middle of the top of the inner side of the test chamber. A liquid level sensor B is installed on the inner side of the bottom of the tank. A partition is fixedly connected to the inner side of the lower part of the tank.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figures 1-5 This utility model provides a technical solution:

[0024] An outdoor direct-connection intelligent variable frequency secondary water supply device includes a main body 1. Disinfection pipes 2 are installed at both ends of one side of the bottom of the main body 1. A placement groove is provided at one end of the outer wall of the disinfection pipe 2. A connecting pipe 3 is connected to the inner side of the placement groove via a quick-lock mechanism. An ultraviolet disinfection lamp 5 is installed near the bottom of the inner wall of the connecting pipe 3. A filter screen 23 is installed at the top of the inner side of the disinfection pipe 2. The quick-lock mechanism includes a locking component, a torsion component, and an anti-accidental contact component. The locking component is used to push and lock the position of the connecting pipe 3, the torsion component is used to release the lock on the connecting pipe 3, and the anti-accidental contact component protects the unlocking component on the torsion component. In use, the device can be locked by pushing and locking the position of the connecting pipe 3 using the locking component, released by the torsion component, and the anti-accidental contact component protects the unlocking component on the torsion component. The device has a simple structure and is easy to operate. If the ultraviolet disinfection lamp 5 malfunctions, the relevant component can be quickly inspected, maintained, or replaced, ensuring that the water supply device can be restored to normal operation in a timely manner, further improving the practicality of the device.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the locking assembly includes an extension plate 4 installed on one side of the outer wall of the connecting pipe 3. An elastic pad 8 is embedded in one side of the extension plate 4, and a through hole is opened at one end of the elastic pad 8. A mating plate 9 is installed on one side of the extension plate 4 corresponding to the through hole. A movable seat 22 is installed on the outer wall of the disinfection pipe 2 near the connecting pipe 3. A mating groove 6 is opened on the outer wall of the movable seat 22 corresponding to the through hole. The mating plate 9 and the mating groove 6 are slidably connected. The elastic pad 8 is a rubber elastic pad. The side cross-section of the connecting pipe 3 is U-shaped. An installation groove 7 is opened inside the movable seat 22 on one side of the mating groove 6. The inner side of the mating groove 6 communicates with the inner side of the installation groove 7. A rotating rod 10 is rotatably connected to one side of the inner wall of the installation groove 7. A pressing plate 11 is sleeved on the outer side of the rotating rod 10. The mating plate 9 and the pressing plate Each end of the extrusion plate 11 has a guide surface 12 that fits against each other. The other end of one side of the extrusion plate 11 has a stretching groove. A first spring 13 is installed inside the stretching groove. The other end of the first spring 13 is fixedly connected to the inner wall of the mounting groove 7. A synchronization block 21 is installed on one side of the extrusion plate 11. A synchronization groove that slides with the synchronization block 21 is opened on the inner wall of the mounting groove 7. First, when replacing or combining the ultraviolet disinfection lamp 5, the connecting tube 3 can be inserted into the placement groove for preliminary positioning. The extension plate 4 and the movable seat 22 contact each other, allowing the docking plate 9 to approach the docking groove 6 and slide into its inner side. This causes one end of the docking plate 9 to enter the inner side of the mounting groove 7 and squeeze the elastic pad 8, forcing it to retract. The extrusion plate 11 is squeezed by the docking plate 9, causing the first spring 13 to be stretched.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a spring-loaded groove is formed inside the extrusion plate 11 at the guide surface 12. A movable rod is rotatably connected to the inside of the spring-loaded groove, and a spring-loaded block 14 is sleeved on the outside of the movable rod. A clamping groove 19 is formed on one side of the docking plate 9 at the guide surface 12. A slope that fits against the guide surface 12 is formed on one side of the spring-loaded block 14. A torsion spring 15 is installed between the movable rod and the inner wall of the spring-loaded groove. Then, when the docking plate 9 is pressed down continuously, it will contact the spring-loaded block 14, causing the torsion spring 15 on the spring-loaded block 14 to be compressed and retracted. When the clamping groove 19 is brought close to the spring-loaded block 14, the spring-loaded block 14 pops out and is placed inside the clamping groove 19. At this time, the operator no longer presses the docking plate 9. After the elastic pad 8 loses pressure, it will rebound a short distance. The spring-loaded block 14 presses against the inner wall of the clamping groove 19, thus completing the clamping of the connecting pipe 3 and the ultraviolet disinfection lamp 5.

[0027] In this embodiment, as Figure 3 , Figure 4 and Figure 5As shown, the torsion assembly includes an operating groove located inside the movable seat 22 on one side of the mounting groove 7. A torsion ring 16 is installed at one end of the rotating rod 10 extending to the inner side of the operating groove. A pushing groove is provided on the outer wall of the movable seat 22 on one side of the operating groove. The inner side of the pushing groove is connected to the inner side of the operating groove. Furthermore, if the ultraviolet disinfection lamp 5 is found to be malfunctioning and unable to work properly, the torsion ring 16 can be pinched to drive the rotating rod 10 to rotate, causing the pressing plate 11 and the spring block 14 to actively move away from the docking plate 9. At this time, the elastic pad 8 fully rebounds and causes the locking groove 19 to rise further. Releasing the torsion ring 16 will not cause it to lock again. At this time, the connecting pipe 3 and the malfunctioning ultraviolet disinfection lamp 5 can be removed together for maintenance.

[0028] In this embodiment, as Figure 3 , Figure 4 and Figure 5 As shown, both the push groove and the operating groove have arc-shaped cross sections. The push plate 17 is slidably connected to the inner side of the push groove. Limiting blocks 18 are installed at both ends of the inner wall of the push groove. Limiting grooves that slidably connect with the limiting blocks 18 are opened on both sides of the outer wall of the push plate 17. A magnetic block 20 is embedded in one end of the push plate 17. An iron block that attracts the magnetic block 20 is embedded in the inner wall of the push groove. A snap-pull groove is opened on the outer wall of the push plate 17. An observation window is embedded in one end of the outer wall of the connecting pipe 3. Furthermore, the snap-pull groove, together with the limiting block 18 and the limiting groove, drives the magnetic block 20 on the push plate 17 to approach the iron block for attraction, covering the torsion ring 16 to prevent personnel from accidentally touching the operating parts after assembly and causing loosening. The filter screen 23 can intercept impurities when the water flows through, further improving the disinfection and purification effect of the water source. The observation window allows for a more intuitive view of whether the ultraviolet disinfection lamp 5 is working properly after installation.

[0029] The implementation principle of an outdoor direct-connection intelligent variable frequency secondary water supply device according to an embodiment of this application is as follows: When replacing or combining the ultraviolet disinfection lamp 5, the connecting pipe 3 can be inserted into the placement groove for initial positioning. The extension plate 4 and the movable seat 22 contact each other, allowing the docking plate 9 to approach the docking groove 6 and slide into its inner side. This causes one end of the docking plate 9 to enter the installation groove 7 and squeeze the elastic pad 8, forcing it to retract. The squeezing plate 11 is squeezed by the docking plate 9, causing the first spring 13 to be stretched. Continuing to press down on the docking plate 9 will cause it to contact the spring pressure block 14, causing the torsion spring 15 on the spring pressure block 14 to be compressed and retracted. After the clamping groove 19 is brought close to the spring pressure block 14, the spring pressure block 14 pops out and is placed inside the clamping groove 19. At this time, the operator no longer presses the docking plate 9. After the elastic pad 8 loses pressure, it will rebound a short distance. The spring pressure block 14 presses against the inner wall of the clamping groove 19, thus completing the connection. The connection between pipe 3 and ultraviolet disinfection lamp 5 is secured. If the ultraviolet disinfection lamp 5 malfunctions and cannot work properly, pinching the torsion ring 16 will rotate the rotating rod 10, causing the squeezing plate 11 and spring block 14 to actively move away from the docking plate 9. At this time, the elastic pad 8 will fully rebound, causing the locking groove 19 to rise further. Releasing the torsion ring 16 will not cause it to lock again. Then, the connecting pipe 3 and the malfunctioning ultraviolet disinfection lamp 5 can be removed together for maintenance. The snap-on groove, together with the limiting block 18 and the limiting groove, will cause the magnetic block 20 on the push plate 17 to approach the iron block for adsorption, covering the torsion ring 16 to prevent personnel from accidentally touching the operating parts after assembly and causing loosening. The filter screen 23 can intercept impurities when water flows through, further improving the disinfection and purification effect of the water source. The observation window allows for a more intuitive view of whether the installed ultraviolet disinfection lamp 5 is working properly.

[0030] The control method of this utility model is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
