Technical Field

[0001] This utility model belongs to the field of industrial equipment monitoring technology, specifically a pump set operation timing alarm device. Background Technology

[0002] As an indispensable piece of equipment in chemical production, chemical pumps are designed and used under very strict requirements to meet the special needs of chemical production, such as high temperature resistance, low temperature resistance, corrosion resistance, wear resistance, and low or no leakage. To ensure the stable operation of pump sets, chemical plant pump sets are usually equipped with various monitoring and protection devices, including alarm timing devices. The alarm timing device can monitor the working status of the pump set in real time. When the pump set has abnormal conditions, such as excessive pressure, excessive flow, excessive temperature, or leakage, the device will immediately issue an alarm and start timing at the same time. In this way, operators can respond quickly and deal with the fault, preventing the accident from escalating further.

[0003] Currently, unplanned damage or shutdown of pump sets due to improper maintenance caused by long operating time is a significant safety hazard in chemical plants. Existing pump sets typically lack intelligent operating time management and rely on manual recording of maintenance time, which can easily lead to missed inspections or overuse. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a pump set operation timer alarm device to solve the problem that in the prior art, pump set operation relies on manual recording of maintenance time, which can easily lead to missed inspections or overuse.

[0005] The pump unit operation timing alarm device includes an assembly plate, a relay is provided on the outer side of the assembly plate, a controller is provided on the outer wall of the assembly plate, a timing module is provided below the controller, and an alarm module is provided on the side of the relay away from the controller. The relay, controller, timing module and alarm module are electrically connected.

[0006] The assembly plate is provided with adjustment holes, the contacts of the relay pass through the adjustment holes, and an adjustment component is provided between the relay and the assembly plate. The adjustment component is used to adjust the installation position of the relay, and positioning components are provided on the left and right side walls of the assembly plate.

[0007] Preferably, the assembly plate is provided with a rubber shock-absorbing pad on the side away from the relay, and a protective shell is provided on the side of the assembly plate away from the rubber shock-absorbing pad. The protective shell covers the relay, timing module, controller and alarm module, but the protective shell has openings on both sides.

[0008] Preferably, the alarm module includes a buzzer powered by an external power source and a flashing light, wherein the flashing light uses a three-color light flashing mode.

[0009] Preferably, the adjustment component includes an installation strip, mating holes, a connecting strip, and a positioning ball. The installation strip is fixedly connected to both sides of the adjustment hole, and the mating holes are evenly distributed at intervals on the top of the installation strip.

[0010] Preferably, the vertical cross-sectional profile of the connecting strip is "L" shaped, and one end is fixedly connected to the relay. The connecting strip is symmetrically distributed on the relay. The positioning ball is installed at the other end of the connecting strip. The positioning ball is a component made of plastic material. The positioning ball cooperates with the mating hole, and the internal area of ​​the mating hole accounts for two-thirds of the total surface area of ​​the positioning ball.

[0011] Preferably, the positioning component includes a positioning plate, a through hole, and a positioning screw. The positioning plate is fixedly installed on the left and right sides of the assembly plate, the through hole is formed inside the positioning plate, and the positioning screw passes through the through hole.

[0014] 1. This utility model installs a relay on the outer wall of the assembly plate. The relay contacts are connected to the auxiliary contacts of the contactor in the original control circuit of the pump group. When the pump group starts working, the relay operates and transmits its signal to the controller. The controller receives the signal, determines whether the pump group is running, and controls the timer to transmit its signal to the timer module to accumulate the effective running time of the pump group. When a certain time is reached, the timer module transmits the signal to the controller, which then triggers the alarm module to issue a signal. This eliminates the need for manual recording of maintenance time, reduces the possibility of missed inspections or overuse during pump group operation, and improves the safety of pump group operation.

Detailed Implementation

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] As attached Figure 1 To be continued Figure 5 As shown:

[0024] Example 1: This utility model provides a pump group operation timing alarm device, including an assembly plate 1, a relay 2 on the outer side of the assembly plate 1, a controller 3 on the outer wall of the assembly plate 1, a timing module 4 below the controller 3, and an alarm module 5 on the side of the relay 2 away from the controller 3. The relay 2, controller 3, timing module 4 and alarm module 5 are electrically connected.

[0025] The assembly plate 1 is provided with adjustment holes 6, the contacts of the relay 2 pass through the adjustment holes 6, and an adjustment component is provided between the relay 2 and the assembly plate 1. The adjustment component is used to adjust the installation position of the relay 2. Positioning components are provided on the left and right side walls of the assembly plate 1.

[0026] It should be noted that by installing relay 2 on the outer wall of assembly plate 1, the contacts of relay 2 are connected to the auxiliary contacts of the contactor in the original control circuit of the pump group. When the pump group starts to work, relay 2 transmits its signal to controller 3. Controller 3 receives the signal, determines whether the pump group is running, and controls the timer to transmit its signal to the timer module 4 to accumulate the effective running time of the pump group. When a certain time is reached, the timer module 4 transmits the signal to controller 3, and controller 3 causes alarm module 5 to issue a signal. There is no longer a need for manual recording of maintenance time, which reduces the possibility of missed inspections or overuse during the operation of the pump group and improves the safety of pump group operation.

[0027] In this embodiment, a rubber shock-absorbing pad 7 is provided on the side of the assembly plate 1 away from the relay 2, and a protective shell 8 is provided on the side of the assembly plate 1 away from the rubber shock-absorbing pad 7. The protective shell 8 covers the relay 2, the timing module 4, the controller 3 and the alarm module 5, but the protective shell 8 has openings on both sides.

[0028] It should be noted that by setting the rubber shock-absorbing pad 7, after the assembly plate 1 is connected to the pump body, the transmission of vibration from the pump body to the assembly plate 1 during operation can be reduced, thus reducing resonance.

[0029] The protective housing 8 can protect the components installed on the mounting plate 1, but its two sides are designed as openings to allow ventilation and improve heat dissipation efficiency.

[0030] In this embodiment, the alarm module 5 includes a buzzer 9 with an external power supply and a light flasher 10, and the light flasher 10 adopts a three-color light flashing mode.

[0031] It should be noted that the alarm module 5 is designed as a buzzer 9 and a flashing light 10, so that when the time is up, it can remind the staff through a combination of sound and light, thereby improving the level of reminder to the staff.

[0032] In this embodiment, the adjustment component includes an installation strip 11, mating holes 12, a connecting strip 13, and a positioning ball 14. The installation strip 11 is fixedly connected to both sides of the adjustment hole 6, and the mating holes 12 are evenly distributed at intervals on the top of the installation strip 11.

[0033] In this embodiment, the vertical cross-sectional profile of the connecting strip 13 is "L" shaped, and one end is fixedly connected to the relay 2. The connecting strip 13 is symmetrically distributed on the relay 2. The positioning ball 14 is installed at the other end of the connecting strip 13. The positioning ball 14 is a component made of plastic material. The positioning ball 14 cooperates with the mating hole 12, and the internal area of ​​the mating hole 12 accounts for two-thirds of the total surface area of ​​the positioning ball 14.

[0034] It should be noted that, through the set adjustment components, the connecting strip 13 is fixedly connected to the relay 2, and the positioning ball 14 is fixedly connected to the connecting strip 13. The positioning ball 14 is designed to be made of plastic, and the internal area of ​​the matching hole 12 occupies two-thirds of the area of ​​the positioning ball 14. Thus, after being inserted into the positioning ball 14, the relay 2 can be fixed. After applying a certain force, the positioning ball 14 can also be pulled out from the matching hole 12. There are multiple matching holes 12, so the installation position of the relay 2 can be adjusted according to the actual installation situation, which improves the installation flexibility.

[0035] In this embodiment, the positioning component includes a positioning plate 15, a through hole 16, and a positioning screw 17. The positioning plate 15 is fixedly installed on the left and right sides of the assembly plate 1. The through hole 16 is opened inside the positioning plate 15, and the positioning screw 17 passes through the through hole 16.

[0036] It should be noted that, by setting up the positioning component, once the position of the assembly plate 1 is determined, the positioning screw 17 is locked onto the pump body by passing through the through hole 16, thereby enabling the installation of the assembly plate 1 and the alarm device.

[0037] In this embodiment, the positioning plate 15 is provided with multiple slots 18 spaced apart on the side away from the relay 2. The slots 18 are arranged perpendicularly to the through hole 16. The slots 18 are provided with a positioning insert plate 19 that is movably connected. The positioning screws 17 pass through the positioning insert plate 19 and are threaded together.

[0038] It should be noted that by setting multiple layers of slots 18 on the positioning plate 15, the positioning screws 17 pass through the positioning insert plate 19, and the positioning insert plate 19 is located in the slots 18. After the positioning screws 17 are tightened, the positioning insert plate 19 is also fixed. Since the rubber shock-absorbing pad 7 is made of elastic material, after the assembly plate 1 is installed, the slots 18 can be disengaged from the positioning insert plate 19 by squeezing the rubber shock-absorbing pad 7. The height of the positioning plate 15 can be adjusted so that the positioning insert plate 19 can be inserted into slots of different heights, thereby adjusting the height of the device and improving the flexibility of installation.

[0039] In the above embodiment, when a timing alarm device needs to be installed on the pump set, the mounting plate 1 is positioned appropriately, the relay 2 is installed on the regulating assembly, the main contact of the contactor controls the power supply to the pump set, and the status (open / closed) of its auxiliary contact synchronously reflects the start / stop status of the pump set; the coil side of the relay 2 is connected to the output terminal of the auxiliary contact (such as the NO contact), and the contact side output is sent to the input port of the control module. The relay 2, by monitoring the changes in the status of the auxiliary contact, converts the mechanical switch signal into an electrical signal that the control module can recognize, thereby achieving indirect detection of the pump set's operating status. The specific workflow is as follows:

[0040] Pump start-up: Contactor main contacts close → Auxiliary contact NO closes → Relay 2 coil is energized → Normally open contact closes → Optocoupler conducts → Control module detects high level and starts timing;

[0041] Pump stops: Contactor main contacts open → Auxiliary contact NO opens → Relay 2 coil de-energized → Normally open contact released → Optocoupler cut off → Control module detects low level and pauses timing.

[0042] After the pump is started, the timing module 4 can calculate the duration. When a certain time is reached, the timing module 4 transmits the signal to the controller 3. The output of the controller 3 is connected to the alarm module 5, which causes the buzzer 9 and the light flasher 10 to emit signals. There is no longer a need for manual recording of maintenance time, which reduces the possibility of missed inspections or overuse during the operation of the pump group and improves the safety of the pump group operation.

[0043] The embodiments of this utility model are given for the purpose of illustration and description. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
