Description

Technical Field

[0001] This utility model relates to the technical field of self-priming can equipment, specifically to a remotely controllable self-priming can. Background Technology

[0002] A self-priming tank is a purely mechanical component used with a pump body. Its core function is to help the pump achieve "self-priming start" through its own cavity design and fluid mechanics principles. Essentially, it solves the problem of the pump "not being able to draw liquid while running dry" by optimizing the mechanical structure. It has no electronic control components and relies solely on fluid pressure, gravity, or mechanical seals to achieve its function. Current traditional remotely controllable self-priming tanks are unable to meet the needs of high-efficiency automation and emergency support: remote control is lacking or unreliable: some self-priming tanks lack remote control functions and rely on manual on-site operation; a few remote control devices can only simply open and close valves and cannot accurately monitor liquid levels, which can easily lead to overflow or water shortage; there is no emergency manual structure, resulting in significant losses in case of failure: when the remote control system fails, there is no convenient manual emergency mechanism, and the equipment must be disassembled to control the valves, resulting in long downtime and affecting the continuity of fluid transportation.

A lifting pipe 3 is slidably connected inside the water inlet pipe 2 via a clearance fit. The lower part of the lifting pipe 3 penetrates into the interior of the self-priming tank 1, and a connecting plate 4 is fixedly connected to its outer side by welding. Four sets of evenly distributed limiting rods 5 are fixedly connected to the lower part of the connecting plate 4 by welding. A base plate 6 is fixedly connected to the lower part of the limiting rods 5 by welding. Floats 7 are sleeved between the limiting rods 5, rising and falling with the liquid level. An infrared rangefinder 8 is fixedly connected to the lower side of the lifting pipe 3 by bolts for monitoring the position of the float 7. A rotating bearing is rotatably connected to the upper side of the water inlet pipe 2. A rotating shaft 18 is fixedly connected to a valve 19 by welding on its outer side, which controls the opening and closing of the water supply pipe 2. A mounting bracket 14 is fixedly connected to the outer side of the water supply pipe 2 by welding. One end of the rotating shaft 18 penetrates the self-priming tank 1 and is rotatably connected to the inner side of the mounting bracket 14 by a deep groove ball bearing. A connecting gear 17 is fixedly connected to the outer side of the rotating shaft 18 by a key. A motor 15 is fixedly connected to the outer side of the mounting bracket 14 by bolts. The power end of the motor 15 is fixedly connected to a power gear 16 by a coupling. The connecting gear 17 meshes with the power gear 16 to drive the valve 19 to rotate. A signal receiver is installed on the outer side of the mounting bracket 14. The signal receiver is electrically connected to the infrared rangefinder 8 and the motor 15 respectively to receive remote control commands. The water supply pipe 2 has symmetrically arranged lifting grooves 9 on both sides. The middle outer side of the lifting pipe 3 is fixedly connected to two sets of lugs 10 by welding. The lugs 10 are slidably connected to the inside of the lifting grooves 9 by clearance fit. The outer side of the water supply pipe 2 is fixedly connected to a fixing ring 13 by welding. The fixing ring 13 and the upper part of the self-priming tank 1 are rotatably connected to a threaded rod 11 by a deep groove ball bearing. The threaded rod 11 is threadedly connected to the inside of one lug 10. The inside of the other lug 10 is slidably connected to a guide rod 12 by clearance fit. The guide rod 12 is fixedly connected to the fixing ring 13 and the upper part of the self-priming tank 1 by welding to provide lifting guidance. A rotating cylinder 21 is rotatably connected to the upper side of the water supply pipe 2 via a deep groove ball bearing. A rectangular groove 22 is opened inside one end of the rotating cylinder 21. A rectangular block 23 is slidably connected inside the rectangular groove 22 via clearance fit. A movable gear 26 is fixedly connected to one end of the rectangular block 23 by welding. The movable gear 26 can mesh with the power gear 16. A rotating rod 27 is fixedly connected to the other side of the movable gear 26 by welding. The rotating rod 27 penetrates the mounting bracket 14 and is fixedly connected to a rotating cap 28 by bolts. The other end of the rectangular block 23 is fixedly connected to a sliding plate 24 by welding. A spring 25 is fixedly connected between the sliding plate 24 and the inner wall of the rotating cylinder 21 by spot welding. The spring 25 is sleeved on the outside of the rectangular block 23. Under normal conditions, it pulls the moving gear 26 to disengage from the power gear 16. A toothed ring 29 is fixedly connected to the inner side of the rotating cap 28 by welding. A toothed groove 30 that matches the toothed ring 29 is opened on the outer side of the mounting bracket 14. When the moving gear 26 meshes with the power gear 16, the toothed ring 29 is embedded in the toothed groove 30, locking the manual operation position. The self-priming tank 1 has an observation window 20 fixed to the front side by bolts for direct observation of the liquid level.

[0015] Working principle: When using this utility model: place the self-priming tank 1 on a flat ground, ensuring that the observation window 20 faces a position that is easy to observe; set the liquid level according to the storage requirements: rotate the threaded rod 11, which rotates through the deep groove ball bearing, driving the side lug 10 to drive the lifting tube 3 to slide along the guide rod 12 and the lifting groove 9, adjusting the highest position of the float 7; connect the power supply, establish a connection between the signal receiver and the remote control center, calibrate the infrared rangefinder 8, and ensure that the position of the float 7 can be accurately monitored.

[0016] When the liquid level in the self-priming tank 1 drops under remote control, the float 7 moves down along the limit rod 5 with the liquid level. The infrared rangefinder 8 detects that the float 7 is below the set threshold and sends a signal to the signal receiver. The remote control center then instructs the motor 15 to start. The motor 15 drives the power gear 16 to rotate, which in turn drives the connecting gear 17 and the rotating shaft 18 to rotate. The valve 19 opens, and the water supply pipe 2 begins to replenish water. When the liquid level rises to the set threshold, the infrared rangefinder 8 sends a signal, the motor 15 rotates in the opposite direction, the valve 19 closes, and water replenishment stops. The observation window 20 allows for direct observation of the liquid level changes.

[0017] In manual emergency operation, when the remote control system malfunctions, pull the rotating cap 28, which drives the rotating rod 27, the moving gear 26, and the rectangular block 23 to compress the spring 25; the moving gear 26 meshes with the power gear 16, and at the same time, the toothed ring 29 on the inner side of the rotating cap 28 disengages from the tooth groove 30 of the mounting bracket 14, unlocking the rotating cap 28; rotate the rotating cap 28, which drives the rotating shaft 18 to rotate through the rotating rod 27, the moving gear 26, the power gear 16, and the connecting gear 17, manually opening and closing the valve 19 to complete the emergency water replenishment or water cut-off; after the emergency ends, the spring 25 resets, the moving gear 26 disengages from the power gear 16, and the remote control mode is restored.
