Multi-stage circulation system water pump linkage device based on mechanical pressure feedback

Abstract

This utility model provides a multi-stage circulation system water pump linkage device based on mechanical pressure feedback, belonging to the technical field of water pump linkage devices. It includes a linkage mechanism comprising a housing, inside which a rectangular plate is fixedly installed. A telescopic rod is fixedly installed on the top of the rectangular plate, and a floating plate is installed on the bottom of the telescopic rod. In this utility model, when the container is full of water, the water pressure increases, causing the floating plate to move upwards. The floating plate, through a mounting bracket, drives the linkage rod to rotate, causing the top rod to press down on a switch, closing the circuit. When water needs to be stored, the water pressure decreases, the spring resets, the floating plate resets, and the top rod moves upwards, no longer pressing the switch, opening the circuit. This solves the problems of high latency and high failure rate in traditional multi-stage water pump systems, which rely on electronic sensor control. The utility model provides a multi-stage circulation system water pump linkage device based on mechanical pressure feedback.

Description

Technical Field

[0001] This utility model relates to the field of water pump linkage device technology, and in particular to a multi-stage circulation system water pump linkage device based on mechanical pressure feedback. Background Technology

[0002] In traditional multistage pump systems, electronic sensor control is widely used for pump start-up, shutdown, and operational status adjustment. However, despite the high level of automation offered by electronic control systems, several problems remain in practical applications, particularly delayed response and a high failure rate. One of the biggest issues with traditional electronic control systems is the inherent latency. When the pump's operating status needs adjustment based on external conditions, feedback information from electronic sensors often requires calculation and judgment by the processor before being transmitted to the controller to start or stop the pump. This information transmission and processing introduces a time delay. Especially under high-load operating conditions, this delay can affect the pump system's efficiency and even prevent the system from responding promptly to emergencies. The high failure rate of traditional electronic control systems is primarily due to the susceptibility of electronic components in sensors and controllers to external environmental influences, leading to damage or malfunction. For example, pump systems may operate under extreme temperature, humidity, or vibration conditions, where the instability of electronic components can cause system malfunctions. Furthermore, the maintenance and replacement costs of electronic equipment are high. For pump systems in special environments, repairing and replacing sensors also increases operating costs and time. Utility Model Content

[0003] The purpose of this invention is to solve the problems of high delay and high failure rate in the traditional multi-stage water pump system with electronic sensor control in the prior art, and to provide a multi-stage circulation system water pump linkage device based on mechanical pressure feedback.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a multi-stage circulating system water pump linkage device based on mechanical pressure feedback, comprising a linkage mechanism, the linkage mechanism comprising a device housing, a rectangular plate fixedly installed inside the device housing, a telescopic rod fixedly installed on the top of the rectangular plate, a floating plate installed at the bottom of the telescopic rod, a spring provided outside the telescopic rod, a linkage rod rotatably connected to the top of the floating plate via a mounting bracket, a rotating shaft fixedly installed on both sides of the linkage rod, a top rod rotatably connected to the bottom of the linkage rod, a mounting shell connected to one side of the device housing via a rectangular block, a squeeze switch installed at the bottom inside the mounting shell, a limit plate installed on one side of the top rod, and a limit groove formed inside the device housing.

[0005] In a preferred embodiment, a movable through hole adapted to the linkage rod is provided on one side of the device housing, and movable grooves are provided on both sides of the movable through hole, with the rotating shaft slidably connected inside the movable grooves.

[0006] In a preferred embodiment, the top of the mounting housing has a through hole adapted to the top rod, and the bottom of the housing is open.

[0007] In a preferred embodiment, the top of the spring is fixedly mounted on the bottom of the floating plate, and the bottom of the spring is fixedly mounted on the top of the rectangular plate.

[0008] In a preferred embodiment, a support mechanism is fixedly installed at the bottom of the linkage mechanism. The support mechanism includes a conical shell fixedly installed at the bottom of the device housing. A screw and a thin rod are installed at the bottom of the conical shell. A threaded cylinder is threadedly connected to the bottom of the screw. A thick cylinder is slidably connected to the bottom of the thin rod. A rotating ball is fixedly installed at the bottom of both the threaded cylinder and the thick cylinder. A base plate is rotatably connected to the bottom of the rotating ball.

[0009] In a preferred embodiment, the bottom of the conical shell is connected to an installation pipe, which is connected to the outlet end of the water pump.

[0010] In a preferred embodiment, the external thread of the coarse cylinder is connected with bolts, and a handle is mounted on the outer surface of the threaded cylinder.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] When the container is full of water, the water pressure increases and enters the device housing. The water drives the float plate upward, and the float plate drives the linkage rod to rotate through the mounting frame. The limit plate limits the top rod, and the top rod presses down to squeeze the switch, closing the circuit. When water needs to be stored, the water pressure decreases, the spring returns to its original position, the float plate returns to its original position, and the top rod moves upward, no longer pressing the squeeze switch, thus opening the circuit. This invention solves the problems of high delay and high failure rate in the existing multi-stage water pump system with electronic sensor control. It provides a multi-stage circulation system water pump linkage device based on mechanical pressure feedback.

[0013] During installation, loosen the bolts on the coarse cylinder, rotate the lever, and the lever will drive the threaded cylinder to rotate. The threaded cylinder rotates and moves outside the screw, and the screw drives the thin rod to move inside the coarse cylinder through the conical shell. The threaded cylinder and the coarse cylinder drive the rotating ball to move, so that the base plate is close to the ground. The base plate rotates on the rotating ball according to the terrain, resulting in better support. Attached Figure Description

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

[0023] Example 1

[0024] like Figures 1-3As shown, this utility model provides a technical solution: a multi-stage circulating system water pump linkage device based on mechanical pressure feedback, including a linkage mechanism 1. The linkage mechanism 1 includes a device housing 11. A rectangular plate 12 is fixedly installed inside the device housing 11. A telescopic rod 13 is fixedly installed on the top of the rectangular plate 12. A floating plate 15 is installed on the bottom of the telescopic rod 13. A spring 14 is provided on the outside of the telescopic rod 13. A linkage rod 16 is rotatably connected to the top of the floating plate 15 through a mounting bracket. Rotating shafts 17 are fixedly installed on both sides of the linkage rod 16. A top rod 19 is rotatably connected to the bottom of the linkage rod 16. A mounting shell 110 is connected to one side of the device housing 11 through a rectangular block. A squeeze switch 111 is installed at the bottom inside the mounting shell 110. The device housing 11 has a movable through hole 18 on one side that matches the linkage rod 16, and movable slots are provided on both sides of the movable through hole 18. The rotating shaft 17 is slidably connected inside the movable slot. The top of the mounting housing 110 has a through hole that matches the top rod 19. The bottom of the device housing 11 is open. The top of the spring 14 is fixedly installed on the bottom of the floating plate 15, and the bottom of the spring 14 is fixedly installed on the top of the rectangular plate 12. A limit plate 112 is installed on one side of the top rod 19. A limit slot 113 is provided inside the device housing 11. When the squeeze switch 111 is pressed down, the power is turned off. When there is no pressure, it automatically pops up and turns on the power. The squeeze switch 111 is electrically connected to the power supply of the water pump through a wire.

[0025] In this embodiment, the support mechanism 2 is installed at the outlet of the water pump. When water is introduced into a container, the water also enters the device housing 11 through the support mechanism 2. However, due to the pull of the spring 14, the water does not cause the float plate 15 to rise. When the container is full, the water pressure increases and enters the device housing 11. The water causes the float plate 15 to move upward, stretching the spring 14. The telescopic rod 13 is limited, and the float plate 15 drives the linkage rod 16 to rotate through the mounting bracket. The linkage rod 16 rotates and moves inside the moving groove through the rotating shaft 17. The limiting groove 113 limits the limiting plate 112, and the limiting plate 112 limits the top rod 19. The top rod 19 presses down on the squeeze switch 111 to close the circuit. When water needs to be stored, the water pressure decreases, the spring 14 resets, the float plate 15 resets, and the top rod 19 moves upward, no longer pressing the squeeze switch 111, thus opening the circuit.

[0026] Example 2

[0027] like Figure 1 and Figure 4As shown, a support mechanism 2 is fixedly installed at the bottom of the linkage mechanism 1. The support mechanism 2 includes a conical shell 21 fixedly installed at the bottom of the device housing 11. A screw 23 and a thin rod 22 are installed at the bottom of the conical shell 21. A threaded cylinder 24 is threadedly connected to the bottom of the screw 23. A thick cylinder 25 is slidably connected to the bottom of the thin rod 22. A rotating ball 26 is fixedly installed at the bottom of both the threaded cylinder 24 and the thick cylinder 25. A base plate 27 is rotatably connected to the bottom of the rotating ball 26. An installation pipe is connected to the bottom of the conical shell 21 and is connected to the outlet end of the water pump. A bolt is threadedly connected to the outside of the thick cylinder 25. A handle is installed on the outer surface of the threaded cylinder 24.

[0028] In this embodiment, during installation, the bolts on the coarse cylinder 25 are loosened, the lever is rotated, and the lever drives the threaded cylinder 24 to rotate. The threaded cylinder 24 rotates and moves outside the screw 23. The screw 23 drives the thin rod 22 to move inside the coarse cylinder 25 through the conical shell 21. The threaded cylinder 24 and the coarse cylinder 25 drive the rotating ball 26 to move, so that the base plate 27 is close to the ground. The base plate 27 rotates on the rotating ball 26 according to the terrain.

[0029] Working principle:

[0030] like Figures 1-4 As shown, the installation pipe is connected to the outlet of the water pump. Rotating the lever causes the threaded cylinder 24 to rotate. The threaded cylinder 24 and the coarse cylinder 25 drive the rotating ball 26 to move, so that the bottom plate 27 is close to the ground. When the container is full of water, the water pressure increases and enters the device shell 11. The water drives the float plate 15 to move upward. The float plate 15 drives the linkage rod 16 to rotate through the mounting frame. The limit plate 112 limits the top rod 19. The top rod 19 presses down on the squeeze switch 111 to close the circuit. When water needs to be stored, the water pressure decreases, the spring 14 returns to its original position, the float plate 15 returns to its original position, and the top rod 19 moves upward, no longer pressing the squeeze switch 111, thus opening the circuit.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
