Description

Technical Field

[0001] This utility model relates to the technical field of equipment for pump room management and maintenance, specifically to a remote monitoring device for water pumps based on the Internet of Things. Background Technology

[0002] In industrial production, municipal water supply, and agricultural irrigation, water pumps are core equipment for liquid transportation, and their stable operation is directly related to production efficiency and people's livelihood. However, water pumps generally face the risk of "dry burning damage" in practical applications. When the liquid level in the pump pool drops below the minimum pumping threshold, the pump impeller, lacking liquid lubrication and cooling, will generate severe friction during high-speed operation, leading to overheating of the motor windings and wear of the mechanical seal. Irreversible damage to the water pump can occur in a short period of time, not only requiring high costs for equipment repair or replacement, but also causing a chain reaction of problems such as production interruptions and water supply stagnation due to shutdown, which has a particularly significant impact on scenarios that rely on continuous liquid supply. Currently, protective measures against water pump dry running have significant limitations. Traditional pump stations mostly rely on manual inspections, where maintenance personnel periodically visit the site to check the water level in the pump pool and the pump's operating status. However, in reality, many pump stations are located in remote areas (such as suburban industrial zones, rural irrigation pumping stations, and mountain water supply points) due to functional requirements or site limitations. Inspection routes are long and cover a wide area, and some pump stations are scattered, resulting in extremely low efficiency for manual inspections. More importantly, most enterprises or management units are limited by labor costs, often assigning a single maintenance person to manage dozens or even hundreds of pump stations, making real-time monitoring difficult. If a sudden drop in the water level in the pump pool occurs during inspection intervals (such as at night or on holidays) (e.g., due to pipeline leaks, insufficient water intake, or a sudden increase in water consumption), the optimal intervention time is easily missed, ultimately leading to water pump dry running.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 This utility model provides a technical solution: A remote monitoring device for water pumps based on the Internet of Things includes: Lifting shell 1, which is fixedly installed above the water pump pumping tank; Lifting block 2 is installed inside lifting shell 1 and can be lifted and lowered inside lifting shell 1. An extension rod 3 is provided at the bottom of lifting block 2, and a hollow plastic ball 4 is provided at the bottom of extension rod 3. Extension rod 3 and hollow plastic ball 4 are placed below lifting shell 1, and hollow plastic ball 4 floats on the liquid surface of water pump pumping tank. Hollow plastic ball 4 can move up and down together with the liquid surface to realize the lifting and lowering of lifting block 2.

[0016] The lifting brush 5 is fixedly installed on the horizontal side of the lifting block 2. The function switch is fixedly installed on the lifting housing 1 at the lifting path corresponding to the lifting brush 5. The function switch includes a warning trigger switch 6 and a forced braking trigger switch 7. The warning trigger switch 6 is located above the forced braking trigger switch 7. The warning trigger switch 6 is electrically connected to the Internet of Things device through a wire. The forced braking trigger switch 7 is electrically connected to the manual reset latching relay on the water pump power supply line through a wire. When the lifting brush 5 moves to the warning trigger switch 6, the lifting brush 5 contacts the warning trigger switch 6, and the two wires at the warning trigger switch 6 are connected to send an electrical signal to the IoT device. The IoT device can then use the network to send warning information to a designated recipient. The manual reset latching relay is connected across the power supply circuit of the water pump. The wires of the forced braking trigger switch 7 are connected to the two trigger points of the relay. When the forced braking trigger switch 7 is triggered by the lifting brush 5, the relay controls the water pump circuit to disconnect, protecting the water pump and preventing it from burning out. The relay must be a manual reset latching relay to prevent the forced braking trigger switch 7 from triggering the circuit again. This utility model does not limit the specific models of the IoT device, water pump, and manual reset latching relay. Any models commonly used by those skilled in the art are applicable, and the IoT warning control and relay circuits all use existing technologies.

[0017] Furthermore, a vertically downward lifting groove 8 is provided inside the lifting housing 1, and the lifting block 2 is engaged within the lifting groove 8. The lifting groove 8 cannot be inclined. Although inclination can increase the distance and improve accuracy, the main requirement of this solution is the accuracy of the descent. Inclination will cause a certain amount of resistance during descent, and the improvement in accuracy of inclination during ascent will not benefit this solution and is therefore not suitable for this solution.

[0018] Furthermore, a limiting groove 9 is provided within the lifting groove 8, and a limiting block 10 corresponding to the limiting groove 9 is provided on the lifting block 2. A horizontal connecting rod 11 is provided on the side of the lifting block 2 away from the lifting brush 5, and a connecting rod clearance hole 12 corresponding to the horizontal connecting rod 11 is provided on the lifting housing 1. The lifting block 2 is fixedly connected to the extension rod 3 through the horizontal connecting rod 11. The limiting groove 9 and the limiting block 10 constrain the lifting direction, which can improve the structural stability.

[0019] Furthermore, a transparent observation window 13 is provided on the front side of the lifting housing 1, and a reference mark is provided on one side of the observation window 13. The position of the lifting block 2 can be observed through the observation window 13 and the reference mark.

[0020] Furthermore, a transparent viewing side cover 14 is provided on one side of the lifting housing 1 corresponding to the extension rod 3. The observation window 13 and the viewing side cover 14 are preferably made of transparent acrylic material, so that the user can observe the internal structure through the viewing side cover 14.

[0021] Furthermore, the lifting brush 5 includes a base block and an arc-shaped conductive sheet 15. The arc-shaped conductive sheet 15 is fixed to the lifting block 2 by the base block, and the arc surface of the arc-shaped conductive sheet 15 faces the function switch.

[0022] Furthermore, the function switch includes two sets of protruding electrical contacts 16, each set of protruding electrical contacts 16 being connected to a wire. The two sets of protruding electrical contacts 16 are electrically connected when they contact the arc-shaped conductive sheet 15. The arc-shaped conductive sheet 15 and the protruding electrical contacts 16 are preferably made of corrosion-resistant copper alloy. When the liquid level in the water pump's pumping tank decreases, the lifting block 2 and the lifting brush 5 descend accordingly. When the lifting brush 5 descends to the warning trigger switch 6, the arc-shaped conductive sheet 15 contacts the two sets of protruding electrical contacts 16 on the warning trigger switch 6, thus connecting the warning trigger switch 6. At this time, the IoT device sends a warning message. When the lifting brush 5 descends to the forced braking trigger switch 7, the arc-shaped conductive sheet 15 contacts the two sets of protruding electrical contacts 16 on the forced braking trigger switch 7, thus connecting the forced braking trigger switch 7. At this time, the relay receives an electrical signal and disconnects the water pump power supply to prevent the water pump from dry burning.

[0023] Structural Description: Lifting shell 1: The main installation and protection structure of the device, fixed above the water pump pumping tank, internally containing components such as lifting block 2 and lifting groove 8, and externally provided with observation window 13 and visual side cover 14, providing support and protection for the overall structure; Lifting block 2: A liftable component set inside the lifting housing 1, connected to the extension rod 3 via the horizontal connecting rod 11, with the lifting brush 5 fixed on the side, moving along the lifting groove 8 as the buoyancy of the hollow plastic ball 4 changes, serving as an intermediate carrier for mechanical transmission and electrical signal triggering; Extension rod 3: A rigid rod-shaped structure connecting the lifting block 2 and the hollow plastic ball 4. One end is fixed to the lifting block 2 through the horizontal connecting rod 11, and the other end is connected to the hollow plastic ball 4, which transmits the buoyancy motion of the hollow plastic ball 4 to the lifting block 2. Hollow plastic ball 4: A lightweight ball located below the lifting shell 1 and floating on the liquid surface of the water pump's pumping tank. It moves synchronously with the rise and fall of the liquid surface by its own buoyancy, providing a power source for the lifting block 2 to rise and fall. Lifting brush 5: A conductive component fixed to the horizontal side of the lifting block 2, including a base block and an arc-shaped conductive sheet 15. The arc surface of the arc-shaped conductive sheet 15 faces the function switch and contacts the protruding electrical contact 16 as the lifting block 2 moves, so as to realize the conduction of electrical signals. Warning trigger switch 6: A function switch fixed on the lifting housing 1 and located above the forced braking trigger switch 7. It includes two sets of protruding electrical contacts 16, which are connected to the Internet of Things device through wires.

Forced braking trigger switch 7: A function switch fixed on the lifting shell 1 and located below the warning trigger switch 6. It includes two sets of protruding electrical contacts 16, which are connected to the manual reset latching relay of the water pump power supply line through wires. After being triggered by the lifting brush 5, it sends a power-off signal. Lifting groove 8: A vertical groove inside the lifting housing 1, used to engage the lifting block 2, constraining the movement trajectory of the lifting block 2 to the vertical direction, ensuring the accuracy of liquid level monitoring, and it cannot be designed with an inclination. Limiting groove 9: An auxiliary groove formed in the lifting groove 8, which cooperates with the limiting block 10 on the lifting block 2 to further limit the movement direction of the lifting block 2, prevent it from deviating or getting stuck during the lifting process, and improve the structural stability. Limiting block 10: A protruding structure set on the lifting block 2 and corresponding to the limiting groove 9, embedded in the limiting groove 9, and cooperating with the limiting groove 9 to constrain the movement direction of the lifting block 2, prevent the lifting block 2 from deviating, and ensure transmission and triggering accuracy; Horizontal connecting rod 11: A horizontal rod-shaped structure connecting the lifting block 2 and the extension rod 3. One end is fixed to the side of the lifting block 2 away from the lifting brush 5, and the other end passes through the connecting rod hole 12 and is fixed to the extension rod 3 to realize the synchronous movement of the lifting block 2 and the extension rod 3. Linkage hole 12: A hole opened on the lifting housing 1, corresponding to the horizontal link 11, to provide movement space for the horizontal link 11, allowing the horizontal link 11 to move freely up and down with the movement of the lifting block 2 and the extension rod 3; Observation window 13: A transparent component (acrylic material recommended) located on the front side of the lifting housing 1, with reference markings on one side, allowing staff to visually observe the real-time position of the lifting block 2, facilitating daily maintenance and status monitoring; Visible side cover 14: A transparent component (acrylic material recommended) installed on the side of the lifting housing 1 corresponding to the extension rod 3, allowing staff to observe the operating status of the internal horizontal connecting rod 11, lifting brush 5 and other structures, and assisting in daily maintenance; Arc-shaped conductive sheet 15: The core conductive component of the lifting brush 5, which is fixed to the lifting block 2 by the base block. It is made of corrosion-resistant copper alloy, with the arc surface facing the function switch. When it contacts the protruding electrical contact 16, it realizes the electrical connection of the two sets of contacts. The protruding electrical contact 16 is a conductive component set on the warning trigger switch 6 and the forced braking trigger switch 7. Each group corresponds to one wire and is made of corrosion-resistant copper alloy. When it contacts the arc-shaped conductive sheet 15, it conducts the circuit and transmits electrical signals.

[0024] Working principle: Before the device is put into operation, the lifting shell 1 must be fixedly installed above the water pump pool, ensuring that the extension rod 3 and the hollow plastic ball 4 below the lifting shell 1 are completely submerged in the liquid in the pool. The hollow plastic ball 4 floats on the liquid surface by its own buoyancy, and its bottom is rigidly connected to the extension rod 3. The top of the extension rod 3 is fixed to the lifting block 2 inside the lifting shell 1 through the horizontal connecting rod 11, forming a synchronous transmission structure of "plastic ball-extension rod 3-lifting block 2". At the same time, the lifting block 2 is engaged in the vertical lifting groove 8 inside the lifting shell 1. The limiting groove 9 in the lifting groove 8 and the limiting block 10 on the lifting block 2 cooperate with each other to strictly constrain the movement direction of the lifting block 2, prevent it from deviating or jamming during the lifting process, and ensure the accuracy of liquid level monitoring.

[0025] When the liquid level in the pumping tank is maintained within a safe range, the hollow plastic ball 4 maintains a stable height along with the liquid level, and the lifting block 2 stops synchronously at the upper position of the lifting trough 8. At this time, the lifting brush 5 (composed of a base block and an arc-shaped conductive sheet 15) fixed on the horizontal side of the lifting block 2 does not contact the function switch on the lifting shell 1, and the device is in standby mode. The staff can directly observe the real-time position of the lifting block 2 through the transparent observation window 13 on the front side of the lifting shell 1 and the reference markings on the side of the observation window 13. They can also check the operating status of the internal horizontal connecting rod 11, lifting brush 5 and other structures through the transparent acrylic viewing side cover 14 on the side of the lifting shell 1, which is convenient for daily maintenance.

[0026] As the liquid level in the pumping tank drops, the hollow plastic ball 4 sinks synchronously with the liquid level. Through the extension rod 3, it drives the horizontal connecting rod 11 and the lifting block 2 to move vertically downward along the lifting groove 8. When the liquid level drops to the "warning threshold", the lifting block 2 drives the lifting brush 5 to descend to the warning trigger switch 6. The warning trigger switch 6 consists of two sets of protruding electrical contacts 16. At this time, the arc-shaped conductive piece 15 on the lifting brush 5 just contacts the two sets of protruding electrical contacts 16, making the two wires of the warning trigger switch 6 conductive, and then sending an electrical signal to the IoT device electrically connected to it. After receiving the signal, the IoT device automatically sends liquid level warning information (such as SMS, APP push) to the designated maintenance personnel through a preset network (such as 4G, WiFi), prompting information such as "liquid level is low, timely inspection and maintenance is required", realizing the remote warning function.

[0027] If the liquid level suddenly drops to the "danger threshold" (i.e., the critical line for the water pump to burn out), the lifting block 2 will drive the lifting brush 5 to descend further to the forced braking trigger switch 7. Similarly, the arc-shaped conductive piece 15 of the lifting brush 5 will contact the two sets of protruding electrical contacts 16 of the forced braking trigger switch 7, making the wires of the forced braking trigger switch 7 conductive and sending a trigger signal to the manual reset latching relay on the water pump power supply line. Since the relay is connected across the water pump power supply circuit and adopts a manual reset latching design, it will immediately cut off the water pump power supply circuit after receiving the electrical signal, forcing the water pump to stop running, thus fundamentally avoiding damage to the water pump due to no liquid being drawn from the pool.

[0028] It is worth noting that after the forced braking is triggered, even if the liquid level in the pumping tank subsequently rises (e.g., after replenishing liquid, the hollow plastic ball 4 drives the lifting block 2 to rise, and the lifting brush 5 disengages from the forced braking trigger switch 7), or if a small current signal triggers again, the manual reset latching relay will remain in the "power-off latching" state. Maintenance personnel must arrive on-site to check the liquid level and troubleshoot the problem before manually resetting the relay to reconnect the water pump power supply circuit. This effectively prevents the water pump from starting accidentally if the fault is not addressed, further improving the safety and reliability of the device. The entire process requires no real-time manual monitoring, making it particularly suitable for remote pump rooms or scenarios with centralized management of multiple pump rooms. This significantly reduces maintenance pressure and extends the service life of the water pump.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
