Abstract
The present application discloses an alarm assembly for pressure pumps, wherein the alarm assembly comprises: an infrared transmitter, the infrared transmitter for mounting on the pressure pump body; an infrared receiver. infrared transmitter for mounting on the pressure pump body; and alarm for mounting on the pressure pump body. If the operator touches the pressure gauge to receive and remove the pressure gauge when the pressure pump is not relieved, the infrared receiver will receive infrared light, which in turn will cause the alarm to be issued by the alarm to alert the operator to the pressure pump, thus avoiding a series of problems such as dismantling the equipment and causing personal injury when the pressure is not relieved.

The portable pressure pump provides controlled gas pressure, while the digital pressure calibrator measures and displays the pressure value of the equipment or system under test. The combination of the two helps the user to check that the equipment or system is working correctly and to make the necessary adjustments and calibrations. The combination of a portable 504408 pressure pump and a digital pressure calibrator can be used to calibrate various pressure transmitters, gauges and other pressure instruments and meters within a certain range in industrial field and laboratory conditions. However, for the high-pressure pressure pump for 5 calibration, due to its relatively high pressure, if inadvertent mistakes are made during the calibration work and the equipment is dismantled without pressure relief, it may cause personal injury and seriously threaten equipment and personal safety.
In order to improve the above, in one aspect of the present application, an alarm assembly is proposed, which, with reference to figures 1 and 2, mainly comprises an infrared transmitter 61, an infrared receiver 62, an alarm 63, a pressure switch assembly 64 and a power supply 65. The infrared transmitter 61 and the infrared receiver 62 are used to detect the presence of foreign objects at the pressure gauge interface 2 and to send an electrical signal to the alarm 63; the alarm 63 is used to receive the above-mentioned electrical signal and to send an alarm; the pressure switch assembly 64 is used to prevent the operator from correctly switch assembly 64 is used to avoid interference with alarm 63 during correct removal of the pressure gauge and to further ensure the safety of the operator; power supply 65 is used to supply power to infrared transmitter 61, infrared receiver 62, alarm 63 and the pressure switch. The power supply 65 is used to power the infrared transmitter 61, infrared receiver 62, alarm 63 and pressure switch.
Specifically, in the exemplary embodiment, the infrared transmitter 61 is mounted on the pressure pump body 1 and set close to the pressure gauge interface 2, furthermore, the infrared transmitter 61 is mounted in such a way that the infrared rays emitted by it are close to the pressure gauge interface 2, such that the infrared receiver 62 is able to receive the infrared light emitted by said infrared transmitter 61 when a foreign object (e.g. a human hand touching the pressure gauge interface 2) is in the way.
Specifically, in the exemplary embodiment, the infrared receiver 62 is mounted on the pressure pump body 1 and set close to the pressure gauge interface 2 so that when a foreign object is in the way at the pressure gauge interface 2, the infrared receiver 62 is able to receive said infrared 62 is able to receive the infrared light emitted by said infrared transmitter 61 and send an electrical signal to the alarm 63 when there is a foreign object in the way of the pressure gauge interface 2.
Further specifically, in the exemplary embodiment, two sets of infrared transmitter 61 and 504408 infrared receiver 62 are provided, and the two sets of infrared transmitter 61 and infrared receiver 62 are provided close to each of the two pressure gauge interface 2, so that the two pressure gauge interfaces 2 of the pressure pump are simultaneously provided with alarm protection.
Specifically, in the exemplary embodiment, the alarm 63 is mounted on the bottom of the pressure pump body 1 to avoid interference with other components, and the alarm 63 is able to receive the electrical signal from the infrared receiver 62 and send an alarm signal.
Further specifically, in the exemplary embodiment, the alarm 63 is an acoustic-optical alarm 63.
Further specifically, in other embodiments, the alarm 63 is any one or more of an acousto-optical alarm 63, a vibrating alarm 63.
Specifically, the pressure switch is used to detect the pressure in the pressure pump body 1 and to control the operation of the alarm 63 when the pressure is below a preset pressure value and to control the operation of the alarm 63 when the detected pressure is above a preset pressure value.
Further specifically, in the exemplary embodiment, the pressure switch comprises a pressure detection module and a control module, wherein the pressure detection module is used to detect the pressure in the pressure pump body 1 and the control module is used to control the operation of the alarm 63.
Further specifically, in other embodiments, the pressure detection module is specifically a pressure detection sensor, which is fixed in the pressure pipe in the pressure pump body 1 and is connected to the control module via a wire and is able to send an electrical signal to the control module; the control module is connected to the alarm 63 via a wire and is able to receive the electrical signal from the pressure detection module and to control the operation of the the operation of alarm 63.

To sum up, firstly, when the pressure pump is not relieved, if the operator touches the 504408 pressure gauge to receive the removal of the pressure gauge, it will make the infrared receiver 62 receive the infrared transmitter 61 and thus make the alarm 63 to play the role of reminding the operator to relieve the pressure of the pressure pump, thus avoiding a series of problems such as removing the equipment when the pressure is not relieved, causing personal injury and seriously threatening the equipment and personal safety. Secondly, by setting the pressure switch assembly 64, when the pressure in the pressure pump body 1 drops to a preset safe pressure value, even if the pressure gauge is dismantled without full pressure relief, the alarm will not be triggered by the alarm 63. If the pressure in pressure pump body 1 is still higher than the preset pressure after pressure relief, alarm 63 will still sound an alarm, thus preventing the operator from being disturbed by alarm 63 when removing the pressure gauge correctly on the one hand, and ensuring that the pressure in pressure pump body 1 is lower than the preset pressure when the gauge is removed on the other. On the other hand, it is possible to ensure that the pressure of the pressure pump body 1 is below the preset pressure value when the pressure gauge is removed, thus further guaranteeing the safety of the operator; again, by setting the power supply 65, it is possible to supply power to the infrared transmitter 61, infrared receiver 62, alarm 63 and pressure switch assembly 64, i.e. to guarantee the continuous and stable operation of the alarm assembly in this application. The alarm assembly in this application operates continuously and stably.

This is a matter of prior art and will not be further elaborated.
Finally, it should be noted that the above is only a preferred embodiment of the present application and is not intended to limit the present application. Despite the detailed description of the present application with reference to the foregoing embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the foregoing embodiments or to make equivalent substitutions to some of the technical features.
