Description

Technical Field

[0001] The utility model relates to the technical field of remote water supply, in particular to a remote water supply pump unit. Background Technique

[0002] In the water supply of water storage type high-rise buildings, a water storage tank is usually set on the roof, and water is pumped into the water storage tank by a booster pump, and then supplied to the users in the building. The water supply system was mainly managed manually before, relying on the staff to regularly inspect each key point of the water supply system to understand the operation status of the water supply system.

[0003] At present, there has also appeared a way of water supply through remote control: a water level sensor is set in the water tank, and the water pump is driven by detecting the water level through the sensor. However, relying solely on the water level sensor is a relatively single method, and the electronic sensor is prone to damage after a long time. When the sensor is damaged, the water pump loses control, which is likely to cause water shortage or water overflow, and there are certain design defects. Content of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the utility model provides a remote water supply pump unit, which solves the problems put forward in the above background technique.

[0006] (2) Technical Solutions

[0007] To achieve the above purposes, the utility model is realized through the following technical solutions: a remote water supply pump unit, including a water tank, a pump one, a pump two, a guide rail, a floating ball, a lifting block and two trigger mechanisms. The pump one and the pump two are connected in parallel on the total water inlet pipe of the water tank. The guide rail is vertically arranged on the water tank. The lifting block is slidably fitted in the guide rail. The floating ball is arranged in the water tank and is connected to the lifting block through a connecting rod. The two trigger mechanisms are vertically arranged in sequence at the lower part of the guide rail. When the lifting block reaches the height of the first trigger mechanism, the pump one is triggered. When the lifting block reaches the height of the second trigger mechanism, the pump two is triggered. An electromagnet switch for disconnecting the circuits of the pump one and the pump two is arranged at the top of the guide rail.

[0008] Preferably, the trigger mechanism includes a slideway, a slider and an electromagnet. The slideway is horizontally arranged on the side of the guide rail. The slider is slidably fitted in the slideway. The electromagnet is arranged at one end of the slideway far away from the guide rail. A magnetic block is arranged on one side of the lifting block corresponding to the slider. The slider is a magnetic body, and the magnetic poles of the surface of the slider corresponding to the magnetic block are the same. When the electromagnet is energized, the magnetic poles of the surface of the electromagnet corresponding to the slider are the same. The electromagnet switch is used to control the electromagnet circuit. Trigger switches one and two for triggering the circuits of the pump one and the pump two are respectively arranged at the slideway ends of the two trigger mechanisms.

[0009] Preferably, the slideway is in a shape with an arched section in the middle and symmetrical horizontal sections on both sides.

[0010] Preferably, pulleys are arranged at the upper and lower ends of the slider.

[0013] (III) Advantageous effects

[0014] The utility model provides a remote water supply pump set, which has the following advantageous effects:

[0015] 1. For the remote water supply pump set, two triggering mechanisms are used in cooperation with Pump One and Pump Two. When Pump One fails, the second triggering mechanism can trigger Pump Two to operate, and at the same time trigger the alarm lamp and the buzzer to give an alarm, effectively preventing the risk of water shortage or water overflow caused by the failure of a single water pump, and providing a stable guarantee for water supply.

[0016] 2. For the remote water supply pump set, by setting the slideway to be arched in the middle and horizontal on both sides, the slider can be prevented from automatically resetting, so that the slider can only reach the end position of the slideway through external force application, avoiding mis-triggering.

[0020] In the figure: 1 water tank, 2 Pump One, 3 Pump Two, 4 triggering mechanism, 5 guiding rail, 6 floating ball, 7 lifting block, 8 connecting rod, 9 alarm lamp, 10 buzzer, 11 magnetic block, 12 electromagnetic switch, 13 limiting plate, 14 alarm switch, 41 slideway, 42 slider, 43 electromagnet, 44 triggering switch one, 45 triggering switch two. Detailed implementation manners

[0021] An embodiment of the utility model provides a remote water supply pump set, as Figures 1-3 shown, which includes a water tank 1, a Pump One 2, a Pump Two 3, a guiding rail 5, a floating ball 6, a lifting block 7, and two triggering mechanisms 4.

[0022] Pump 1-2 and pump 2-3 are connected in parallel on the main inlet pipe of water tank 1, where pump 2-3 serves as a standby pump.

[0023] The guide rail 5 is vertically arranged on the water tank 1. The lifting block 7 is slidably fitted inside the guide rail 5. The floating ball 6 is arranged inside the water tank 1 and is connected to the lifting block 7 through a connecting rod 8. The floating ball 6 floats up and down according to the water level height and drives the lifting block 7 to move up and down through the connecting rod 8.

[0024] Two groups of trigger mechanisms 4 are vertically arranged in sequence at the lower part of the guide rail 5. When the lifting block 7 reaches the height of the first trigger mechanism 4, the water level reaches the first warning line at this time, usually with a remaining 20 cm, and pump 1-2 is triggered. When the lifting block 7 reaches the height of the second trigger mechanism 4, the water level reaches the second warning line at this time, usually with a remaining 10 cm, and pump 2-3 is triggered. An electromagnet switch 12 for disconnecting the circuits of pump 1-2 and pump 2-3 is arranged at the top of the guide rail 5. The circuits of pump 1-2 and pump 2-3 are in parallel.

[0025] The trigger mechanism 4 includes a slideway 41, a slider 42, and an electromagnet 43. The slideway 41 is horizontally arranged on the side of the guide rail 5. The slideway 41 is in a shape with an arched section in the middle and symmetric horizontal sections on both sides. The slider 42 is slidably fitted inside the slideway 41, and pulleys are arranged at the upper and lower ends of the slider 42. By setting the slideway 41 to be arched in the middle and horizontal on both sides, it can prevent the slider 42 from automatically resetting, so that the slider 42 can only be controlled to reach the end position of the slideway 41 by an external force, avoiding false triggering.

[0026] The electromagnet 43 is arranged at one end of the slideway 41 far from the guide rail 5. A magnetic block 11 is arranged on one side of the lifting block 7 corresponding to the slider 42. The slider 42 is a magnetic body, and the magnetic pole of the surface of the slider 42 corresponding to the magnetic block 11 is the same. When the electromagnet 43 is energized, the magnetic pole of the surface corresponding to the slider 42 is the same. The magnetic forces of the magnetic block 11 and the electromagnet 43 used should be able to push the slider 42 from one end of the slideway 41 to the other end.

[0027] As Figure 3 shown, when the lifting block 7 reaches the position of the first trigger mechanism 4, the magnetic block 11 pushes the slider 42 to the other end of the slideway 41, making it contact the first trigger switch 44. The first trigger switch 44 triggers the signal transmitter to emit a signal. The signal receiver receives the signal and controls the start of pump 1-2 through the controller.

[0028] When pump 1-2 fails, the water level continues to drop. When the lifting block 7 reaches the position of the second trigger mechanism 4, the magnetic block 11 pushes the slider 42 to the other end of the slideway 41, making it contact the second trigger switch 45. The second trigger switch 45 triggers the signal transmitter to emit a signal. The signal receiver receives the signal and controls the start of pump 2-3 through the controller.

[0029] The electromagnet switch 12 is used to control the circuit of the electromagnet 43. Trigger switches 44 and 45 for triggering the circuits of pump one 2 and pump two 3 are respectively arranged at the end parts of the slideways 41 of the two trigger mechanisms 4. When pump one 2 or pump two 3 is started, the water level continuously rises. During this process, the water pump does not stop. The lifting block 7 rises as the water level rises. When it reaches the full water level height, the lifting block 7 touches the electromagnet switch 12, making the electromagnet 43 energized. The energized electromagnet 43 pushes the slider 42 to the end of the slideway 41 far away from it. The slider 42 disengages from the trigger switch 44 and the trigger switch 45, cutting off the power supply of the water pump and stopping it.

[0030] This device further includes an alarm lamp 9 and a buzzer 10 connected in series on the same circuit. A limit plate 13 is arranged at the lower part of the guide rail 5. An alarm switch 14 corresponding to the lifting block 7 is arranged on the limit plate 13. The alarm switch 14 is used to trigger the alarm lamp 9. When the lifting block 7 reaches the height of the lowest slideway 41, it touches the alarm switch 14 on the lifting plate 13, triggering the alarm lamp 9 and the buzzer 10 while triggering pump two 3, which is used to remind the operator that the standby pump two 3 has been started and pump one 2 may be damaged, reminding that maintenance is needed.

[0031] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
