Description

Technical Field

[0001] The present application relates to the field of water pump technology, and in particular to an intelligent water level monitoring device for a water pump. Background Art

[0002] A water pump is a machine that transports or pressurizes liquids. It transfers mechanical energy from a prime mover or other external energy to the liquid and is typically driven by an electric motor. Water pumps can be either submersible or dry. Dry pumps cannot be placed in water to prevent direct contact between key components, such as the motor, and water. During pumping operations, the water level must be constantly monitored to prevent cavitation damage caused by idling.

[0003] However, in some cases, such as poor pumping environment, deep pumping environment, and dark wells, manual observation is impossible. The setting of manual workstations increases costs, making it impossible to effectively observe the operation of the pump at all times and to know the depth of the pump water level at all times. Summary of the Invention

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] Reference Figure 1 and Figure 2 A water pump water level intelligent monitoring device includes a floating box 2 for placing a water pump 1. The side wall of the floating box 2 is provided with a pipe opening 211, and the lower side is provided with a ruler opening 212. A tape measure 3 and a camera 4 are placed in the floating box 2. The tape measure 3 is provided with a ruler 31. The ruler 31 extends from the ruler opening 212, and a weight 5 is fixed at the end. The camera 4 is used to shoot the ruler 31. The camera 4 is communicatively connected to a main control chip, and the main control chip is used to communicate with the motor of the water pump 1.

[0028] The floating box 2 floats on the water surface under the buoyancy of the water, and the ruler 31 is pulled out of the tape measure 3 downward under the gravity of the weight 5 until the weight 5 touches the bottom, and the tape measure 3 remains vertical. When the water level rises, the ruler 31 of the tape measure 3 is pulled downward under the action of the weight 5. When the water level drops, the ruler 31 of the tape measure 3 is pulled back by the spring of the tape measure 3. During the whole process, the camera 4 captures the numerical value of the ruler 31 at all times and transmits it to the main control chip. The main control chip is set with a water level threshold. The main control chip is communicated with the motor of the water pump 1. When the value of the ruler 31 obtained by the capture is less than the threshold, the main control chip controls the motor of the water pump 1 to turn off the water pump 1. When it is not less than the threshold, the water pump 1 is controlled to turn on, so as to solve the current technical problem of being unable to observe the water level at all times and reduce the idling phenomenon of the water pump 1.

[0029] The pipe opening 211 is used for a pipe connected to the water inlet of the water supply pump 1 to pass through.

[0030] The measuring tape 3 can be a waterproof measuring tape that can be purchased from the market and installed. The strip 31 of the measuring tape 3 is coated with a waterproof material to form a waterproof layer to achieve a waterproof effect.

[0031] The camera 4 can be a commercially available waterproof camera.

[0032] The main control chip, which can be a single-chip microcomputer (MCU), recognizes and calculates the image information captured by camera 4, obtains the data of ruler 31 captured in real time by camera 4, and compares it with a threshold value (for example, the threshold value is set to 1 meter, which is the minimum water level value for the normal operation of water pump 1). The main control chip uses the detected water level signal, the submersible pump bottom support signal, and the submersible pump position signal to determine the water level. If the water level does not reach the threshold value, for example, the water level does not reach the water level that allows water pump 1 to operate normally, the main control chip shuts down the motor of water pump 1 to prevent damage to water pump 1.

[0033] Reference Figure 1 and Figure 2 The main control chip is also communicatively connected to the display terminal module and the alarm module.

[0034] The main control chip transmits the numerical information of the scale bar 31 captured by the camera 4 to the display terminal module so as to understand the changes in water level in real time, and controls the alarm module to issue an alarm prompt when the water level is lower than the threshold so as to manually determine that the water pump 1 is in the off state.

[0035] Among them, the display terminal module can be a background computer monitoring center, a mobile phone, etc.

[0036] The alarm module can be a display, a buzzer, etc.

[0037] The main control chip is also connected to a charging module, which is also connected to the camera 4. The charging module can use a button battery to charge the main control chip and the camera 4 at the same time through the charging module.

[0038] Reference Figure 1 and Figure 2 The floating box 2 includes a box body 21 with an upper opening structure and a baffle 22 installed in the box body 21. The baffle 22 is horizontally arranged and forms a seepage chamber with the bottom of the box body 21 for installing the water pump 1. The pipe opening 211 and the ruler opening 212 are both opened on the baffle 22.

[0039] The water pump 1 is located on the upper side of the water baffle 22 so that the water and the water pump 1 are isolated by the water baffle 22 to prevent the water from affecting the operation of the water pump 1.

[0040] The box body 21 is an upper opening structure so as to accommodate the water pump 1 , and the water baffle 22 is installed by means of a threaded connection so as to facilitate assembly and disassembly.

[0041] The box body 21 is a hollow structure to reduce weight and generate buoyancy.

[0042] The pipe opening 211 is located above the baffle 22 so that the water inlet pipe of the water pump 1 can be extended downward from above the baffle 22 into the water surface.

[0043] The ruler opening 212 is opened through the bottom of the box body 21 and is located in the center of the box body 21. This ensures that the center of gravity of the weight 5 and the floating box 2 are on the same vertical line, ensuring that the stability of the floating box 2 will not be affected by the pulling of the weight 5.

[0044] In addition to the above embodiment, the flotation tank 2 further includes a plurality of floating plates 23 evenly distributed around the tank body 21. One end of the floating plates 23 is fixedly connected to the tank body 21, and the height of the floating plates 23 is lower than the baffles 22. The plurality of floating plates 23 increases the buoyancy of the entire flotation tank 2 and prevents the flotation tank 2 from tipping over.

[0045] The box body 21 and the floating plate 23 can be made of lightweight materials such as rubber and foam.

[0046] The floating box 2 also includes a storage box 24 fixedly connected to the lower side of the baffle 22. The lower side of the storage box 24 is higher than the upper side of the floating plate 23. The tape measure 3 and the camera 4 are both installed in the storage box 24, and a through hole 241 is opened on the lower side of the storage box 24 for the ruler 31 to pass through.

[0047] The tape measure 3 and the camera 4 are protected by the storage box 24 , and the storage box 24 is higher than the floating plate 23 , which can prevent water from entering the storage box 24 .

[0048] On the basis of the above embodiment, a cleaning cotton 242 is provided on the hole wall of the through hole 241 . The cleaning cotton 242 abuts against the side of the ruler 31 to wipe the moisture brought by the ruler 31 when it is recovered and keep it dry.

[0049] Reference Figure 1 and Figure 2 The weight 5 includes a weight box 51 with a flat bottom surface. The weight box 51 is open upward, and the opening size is adapted to the size of the lower end of the floating box 2.

[0050] When the water level drops and the floating box 2 falls, the floating box 2 can fall into the opening of the weight box 51, thereby protecting the floating box 2 and its internal components such as the water pump 1.

[0051] A drainage hole 511 is provided through the bottom of the weight box 51 so that when the water level drops and the floating box 2 falls into the weight box 51 , the water in the weight box 51 can be drained out in time.

[0052] The size of the upper opening of the heavy object box 51 is adapted to the size of the lower end of the floating box 2 to ensure that the floating box 2 will not move after falling into the heavy object box 51.

[0053] The weight 5 further includes a plurality of pull ropes 52 , which are uniformly distributed around the weight box 51 , and each pull rope 52 has one end fixedly connected to the inner wall of the opening of the weight box 51 and the other end connected to the end of the ruler 31 .

[0054] The weight box 51 and the ruler 31 are connected by a plurality of pull ropes 52 , and the balance of the weight box 51 is maintained.

[0055] Moreover, a slope 512 connected to the bottom of the weight box 51 is formed at the root of the inner wall of the weight box 51, and the lower outer wall of the floating box 2 is adapted to the slope 512 so that the floating box 2 can fall accurately into the weight box 51.

[0056] The bottom of the weight box 51 is a sloped structure that slopes downward toward the drain hole 511 to ensure sufficient drainage of water. One end of each pull cord 52 is fixedly connected to the bottom of the opening of the weight box 51. With the bottom of the box body 21 being a flat surface, after the box body 21 falls into the weight box 51, the bottom of the box body 21 and the bottom of the opening of the weight box 51 form a space for each pull cord 52.

[0057] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
