[0032] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0033] Example 1

[0034] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, this embodiment discloses a vacuum degree detection system for a pump room vacuum system, including: a vacuum pump 1, the vacuum pump 1 is connected to a water source for water supply, the vacuum pump 1 is provided with a driving device 2, the driving device 2 is used to drive the vacuum pump 1 to work, the vacuum pump 1 is provided with a water inlet pipe and a water outlet pipe, and water is pumped by the vacuum pump 1 for water supply. It also includes a vacuum detection device 3, a pressure compensation device 4 and a flow stabilizing device 5. The vacuum detection device 3 is used to monitor the vacuum degree in the vacuum pump 1. The pressure compensation device 4 is arranged on one side of the vacuum detection device 3 and is located at the output end of the vacuum pump 1. The pressure compensation device 4 is used to provide pressure replenishment and stable water supply when the vacuum pump 1 fails. The flow stabilizing device 5 is arranged on the water inlet pipe of the vacuum pump 1. The flow stabilizing device 5 connects the vacuum pump 1 and the water source tank. When supplying water to residential buildings, water is pumped and supplied through the vacuum pump 1. The vacuum degree of the vacuum pump 1 is monitored through the vacuum detection device 3. When a problem occurs in the vacuum pump 1, the pressure at the water outlet and water inlet of the vacuum pump 1 is compensated through the pressure compensation device 4 and the flow stabilizing device 5 to achieve stable water supply, which has the effect of monitoring the vacuum pump 1 in the pump room and compensating for water supply.

[0035] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4In order to stably drive the vacuum pump 1 to operate, a driving device 2 is provided at the blade shaft end of the vacuum pump 1. The driving device 2 includes a stepper motor 21. The output shaft of the stepper motor 21 is connected to the blade shaft end of the vacuum pump 1.

The vacuum pump 1 is driven to operate through the coupling 22 to separate the stepper motor 21 from the vacuum pump 1 to prevent the vacuum pump 1 from being damaged by water flowing into the stepper motor 21 and causing damage to the stepper motor 21.

[0036] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The vacuum detection device 3 includes a rotating rod 31, which is rotatably connected to the water outlet pipe. A detection tube 32 is provided on the water outlet pipe. The detection tube 32 is connected to the water outlet pipe. The rotating rod 31 rotates through the water outlet pipe. The rotating rod 31 is fixedly connected to the speed measuring paddle 33 on the outer wall of the water outlet pipe. The blades of the speed measuring paddle 33 are arranged along the water outlet pipe and the detection tube 32 and are driven to rotate by the water flow on the water outlet pipe of the vacuum pump 1. The protruding end of the rotating rod 31 is provided with a speed measuring component 34, which is used to monitor the speed of the speed measuring paddle 33. The speed measuring component 34 includes a speed sensor 341, which is arranged at the protruding end of the rotating rod 31.

When the vacuum pump 1 is operating stably, the water flow rate output by the vacuum pump 1 is constant, and the water flow rate of the outlet pipe is monitored by the speed measuring paddle 33 on the rotating rod 31. When the water flow rate is abnormal, the vacuum pump 1 is damaged, and the pressure compensation device 4 is opened in time to work through the data transmitted by the speed sensor 341.

[0037] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The pressure compensation device 4 includes a branch pipe 1 41, a branch pipe 2 42, and a plunger 43. The branch pipe 1 41 is connected to the branch pipe 2 42 and is connected to the water outlet pipe to divert the water outlet pipe. The branch pipe 1 41 is provided with a transmission assembly 44, which is used to drive the plunger 43 to move along the branch pipe 1 41 and perform pressure compensation. The branch pipe 2 42 is provided with water outlet components 47 at both ends, which are used to transmit the water flow transported by the water outlet pipe. The water outlet components 47 include a one-way valve 471, which is respectively provided at the water inlet end and the water outlet end of the branch pipe 2 42. The one-way valve 471 is used to transmit the water flow. When the vacuum pump 1 is detected to be damaged, the plunger 43 on the branch pipe 2 42 is moved to increase the outlet pressure in the branch pipe 1 41 and the water outlet pipe, thereby increasing the water flow rate on the water outlet pipe and thus achieving normal water supply.

[0038] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The transmission assembly 44 includes a transmission tube 441, a reciprocating screw rod 442 and a connecting block 443. The transmission tube 441 is connected to the branch pipe 1 41, and the reciprocating screw rod 442 is rotatably connected to the transmission tube 441. Both ends of the reciprocating screw rod 442 are rotatably passed through the transmission tube 441. Power components 45 are provided at both ends of the reciprocating screw rod 442. The power component 45 is used to drive the reciprocating screw rod 442 to rotate. One end of the connecting block 443 is fixedly connected to the plunger 43. The connecting block 443 is threadedly sleeved on the reciprocating screw rod 442. A guide hole is provided at the connection between the transmission tube 441 and the branch pipe 1 41. The connecting block 443 moves along the guide hole, and the reciprocating screw rod 442 drives the plunger 43 to move back and forth along the branch pipe 2 42, thereby realizing the pressure regulation in the branch pipe 1 41 and the water outlet pipe, increasing the water outlet flow rate of the vacuum pump 1, and thus supplying water normally when the vacuum pump 1 is damaged.

[0039] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 In order to stably drive the reciprocating screw rod 442 to operate, a power assembly 45 is provided at the shaft end of the reciprocating screw rod 442. The power assembly 45 includes a first motor 451, a second motor 452 and an overload assembly 453. The first motor 451 or the second motor 452 is connected to the reciprocating screw rod 442. The shaft ends of the first motor 451 and the second motor 452 are respectively provided with an overload assembly 453. The overload assembly 453 includes two sets of connecting disks 4531. The peripheral walls of the two connecting disks 4531 are provided with a card slot 4532. An overload rod 4533 is provided between the two connecting disks 4531. The overload rod 4533 is made of a nylon rod. The overload rod 4533 is arranged in the slot 4532 and connected to two connecting plates 4531. One connecting plate 4531 is connected to the output shaft of the first motor 451 or the output shaft of the second motor 452, and the other connecting plate 4531 is connected to the shaft end of the reciprocating screw 442. The shaft end of the reciprocating screw 442 is provided with a polygonal shaft. The connecting plate 4531 is provided with a shaft groove. The polygonal shaft and the shaft groove are arranged one-to-one. A conversion assembly 46 is provided on the transmission tube 441. The conversion assembly 46 is used to replace the first motor 451 or the second motor 452. Because the reciprocating screw 442 drives the connecting block 443 to move, thereby achieving the reciprocating movement of the plunger 43, and the movement of the plunger 43 consumes a lot of power, which can easily cause damage to the motor. In addition, when the first motor 451 or the second motor 452 is overloaded, the nylon rod between the two connecting plates 4531 twists and acts as a buffer to prevent overload damage to the first motor 451 or the second motor 452.

[0040] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The conversion assembly 46 includes a driving motor 461, a threaded rod 462 and a driving block 463. The threaded rod 462 is rotatably connected to the transmission tube 441 and is horizontally arranged. The driving motor 461 is connected to the rotating shaft end of the threaded rod 462. The driving block 463 is respectively arranged on the first motor 451 and the second motor 452. The driving block 463 is threadedly sleeved on the threaded rod 462. The threaded rod 462 drives the driving block 463 to move horizontally to replace the first motor 451 or the second motor 452. The driving motor 461 drives the threaded rod 462 to rotate and move the driving block 463 on the threaded rod 462, thereby realizing the replacement of the first motor 451 or the second motor 452 on the driving block 463.

[0041] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The flow stabilizing device 5 includes a flow stabilizing tank 51 and a vacuum suppressor 52. The flow stabilizing tank 51 is connected to the water inlet pipe, and the vacuum suppressor 52 is arranged on the flow stabilizing tank 51. The flow stabilizing tank 51 type non-negative pressure water supply equipment is directly connected to the municipal pipeline network, and the water is supplied in series and superimposed on the basis of the residual pressure of the municipal pipeline network.

[0042] (1) Variable frequency constant pressure water supply: When the water supply of the municipal pipe network is greater than the water consumption of the user, the stabilizing tank 51 type non-negative pressure water supply equipment uses variable frequency constant pressure water supply. At this time, a certain amount of pressurized water is stored in the stabilizing tank 51.

[0043] (2) Elimination of negative pressure: When the user's water consumption increases, the pressure at the connection between the municipal pipe network and the surge tank 51 drops. When the pressure drops below the relative pressure of 0, a negative pressure is formed in the surge tank 51, the air inlet valve of the vacuum suppressor 52 opens, and the atmosphere enters the surge tank 51. At this time, the surge tank 51 is equivalent to an open water tank with a free liquid surface. The pressure is the same as that of the atmosphere, and the negative pressure is eliminated. When the water level drops to the set value, the liquid level controller transmits the control signal to the control system in the frequency conversion control cabinet to control the compressor unit to stop working and the user's water supply is cut off; when the user's water consumption decreases, the water level in the surge tank 51 rises, and the gas is discharged from the exhaust valve of the vacuum suppressor 52. After the pressure returns to normal, the compressor unit automatically restarts and the water supply is restored.

[0044] The working principle of the vacuum degree detection system of the pump room vacuum system of this embodiment is as follows: when supplying water to residents, the vacuum pump 1 is driven by the driving motor 461 to operate and deliver water, and the speed sensor 341 on the speed measuring paddle 33 is used to monitor the flow rate of the water flow. When the vacuum pump 1 is working normally, when the flow rate of the water flow changes due to the stator water flow rate, that is, the vacuum pump 1 is damaged and cannot be replaced in time, the first motor 451 or the second motor 452 drives the plunger 43 to move in the branch pipe 42 to provide pressure compensation on the water outlet pipe. The plunger 43 moves in the branch pipe 42 to pressurize the branch pipe 42 to compensate the output pressure of the vacuum pump 1, and the water flow is pressurized and delivered for water supply. When the first motor 451 is damaged, the threaded rod 462 is driven by the driving motor 461 to move, thereby driving the driving block 463 to drive the first motor 451 to disengage the reciprocating screw 442 and connect the output shaft of the second motor 452 to the reciprocating screw 442 for operation, thereby replacing the motor, which has the effect of monitoring the pump room vacuum pump 1 and compensating the water supply.

[0045] Example 2

[0046] The difference between this embodiment and embodiment 1 is that the power assembly 45 includes a hydraulic cylinder, and the protruding end of the hydraulic cylinder is connected to the connecting block 443. The hydraulic cylinder drives the connecting block 443 to move back and forth along the guide hole to realize the reciprocating movement of the piston 43 in the branch pipe 2 42, thereby realizing pressure compensation between the branch pipe 1 41 and the water outlet pipe.

Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
