Description

Technical Field

[0001] The present invention relates to a ground water remover mainly used for removing water on outdoor stadiums and courts. Background Art

[0002] Due to the inconsistency of the ground elevation during the construction of a basketball court, the non-simultaneity of the construction process, and the difference in stress at different places during use, after the court has been used for a period of time, whether it is a cement floor or a rubber floor, local depressions will always appear. After rain, there will be thin pools of water, which brings inconvenience to the use of the court. To remove the accumulated water, a common method is to use a water pusher. It has a simple structure, is easy to operate, and has a low price, and is widely used in schools. However, this device has great defects: it only pushes the accumulated water from one place on the court to another place, from a place with more water to a place with less water, and the originally dry place becomes wet instead; secondly, since the main component of the wiper is a straight hard thin sheet, the accumulated water in the depressed place is still not removed.

[0021] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention and make the above-mentioned objects, features, and advantages of the embodiments of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0022] As Figure 1 and 2 shown, a ground water remover provided by the present invention includes a main body 1 and wheels 2. The main body 1 is provided with a hollow housing 3. The lower end of the housing 3 is provided with an opening 4. A misting pad 5 is horizontally arranged at the opening 4. The misting pad 5 is provided with a plurality of holes, and each hole is inlaid with a microporous misting sheet 6. The housing 3 is internally provided with a lifting mechanism for driving the misting pad 5 to lift and lower, and the housing 3 is also internally provided with a discharge channel 7 for discharging water mist.

[0023] In an embodiment of the present invention, the wheels 2 are provided to facilitate the staff to push the present invention to the water accumulation location. A brake can be provided at the wheels 2 to facilitate the present invention to stay in a certain place. The microporous misting sheet 6 can turn the accumulated water into small water droplets of mist and spray it out in a mist shape. When the present invention works specifically, it is pushed to the water accumulation location, and the lifting mechanism drives the misting pad 5 to vertically descend to the water surface. The plurality of microporous misting sheets 6 perform atomization operation on the accumulated water, which can turn the accumulated water into small water droplets of mist and spray it out in a mist shape through the hollow housing 3 and the discharge channel 7. To accelerate the spraying speed, an exhaust fan 8 is provided in the discharge channel 7. To achieve the purpose of uniform atomization, the plurality of microporous misting sheets 6 can be arranged in a matrix, and the distance between two adjacent microporous misting sheets 6 can be very small. The shape of the microporous misting sheet 6 can be circular, with a diameter of 20 mm. The misting pad 5 is impermeable to water, and each hole is inlaid with a microporous misting sheet 6, and water cannot pass through the holes.

[0024] As Figure 3 shown, a liquid sensor is provided on the lower surface of each microporous misting sheet 6. The liquid sensor and the microporous misting sheet 6 are both electrically connected to a controller. When a certain liquid sensor detects liquid, it sends a signal to the controller, and the controller controls the driving unit to drive the microporous misting sheet 6 corresponding to the liquid sensor to perform atomization work.

[0025] Specifically, the water remover provided by the present invention is pushed to the water accumulation location, and the atomizing pad 5 is driven by the lifting mechanism to vertically descend to the water surface. At this time, some or all of the liquid sensors come into contact with the accumulated water. Since the liquid sensors are relatively small, when they come into contact with the accumulated water, the corresponding microporous atomizing sheets 6 will also come into contact. Some or all of the liquid sensors can detect the liquid and send signals to the controller, and the controller controls the driving unit to drive the microporous atomizing sheet 6 corresponding to the liquid sensor to perform atomizing work. Sometimes the accumulated water is relatively deep. When the descending height of the atomizing pad 5 is insufficient, the liquid sensors cannot detect the liquid. At this time, the lifting mechanism further drives the atomizing pad 5 to descend, and the corresponding work is completed by the liquid sensors, the controller, and the microporous atomizing sheets 6 until the accumulated water is completely cleared. After all the accumulated water is cleared, the lifting mechanism drives the atomizing pad 5 to rise. The controller can adopt the S7-200 model of Siemens PLC. In this embodiment, the driving units of each microporous atomizing sheet 6 are independent of each other, work independently during water removal without affecting each other, are controlled by corresponding switches, have a low failure rate and high reliability, and can achieve the purpose of energy saving. One microporous atomizing sheet 6 can atomize 3-5 L of accumulated water per minute, and the atomizing speed is very fast.

[0026] As a specific embodiment, in order to accelerate the complete clearing of the accumulated water, the atomizing pad 5 bulges downward. The atomizing pad 5 is made of a soft, insulating and water-impermeable material. The atomizing pad 5 can be a thin flexible insulating dielectric film. The bulging atomizing pad 5 can adapt to the terrain of the water accumulation area, so that the atomizing pad 5 is laid on the bottom surface of the water accumulation area, and the accumulated water can be completely cleared at one time. This embodiment is particularly suitable for water accumulation areas with large depressions and irregular depressions, and solves the technical problem of incomplete water removal due to uneven ground. Specifically, the water remover provided by the present invention is pushed to the water accumulation location, and the atomizing pad 5 is driven by the lifting mechanism to vertically descend to the water surface. Since the atomizing pad 5 bulges downward, the atomizing pad 5 can be further lowered or directly lowered to the bottom surface of the water accumulation area without first clearing the accumulated water on the water surface and then further lowering. At this time, some or all of the liquid sensors come into contact with the accumulated water. Since the liquid sensors are relatively small, when they come into contact with the accumulated water, the corresponding microporous atomizing sheets 6 will also come into contact. Some or all of the liquid sensors can detect the liquid and send signals to the controller, and the controller controls the driving unit to drive the microporous atomizing sheet 6 corresponding to the liquid sensor to perform atomizing work. If the atomizing pad 5 is directly lowered to the bottom surface of the water accumulation area, then the microporous atomizing sheet 6 keeps performing atomizing work until the liquid sensors cannot detect the liquid, indicating that the accumulated water in the water accumulation area has been cleared, and the accumulated water can be completely cleared at one time.

[0027] Such as Figure 2As shown, the lifting mechanism includes a cylinder 9 and a connecting frame 10. The cylinder 9 is fixed to the housing 3. The cylinder 9 is vertically arranged, and the connecting frame 10 is horizontally arranged. The connecting frame 10 is located below the cylinder 9. The output shaft of the cylinder 9 faces and is fixed to the connecting frame 10. The atomizing pad 5 is fixed to the connecting frame 10, and the atomizing pad 5 is located below the connecting frame 10.

[0028] Specifically, when it is necessary to lower the atomizing pad 5, the cylinder 9 is opened to extend the output shaft of the cylinder 9, and the connecting frame 10 drives the atomizing pad 5 to descend; when it is necessary to raise the atomizing pad 5, the cylinder 9 is opened to shorten the output shaft of the cylinder 9, and the connecting frame 10 drives the atomizing pad 5 to rise.

[0029] As a specific embodiment, the four corners of the atomizing pad 5 are fixed to the connecting frame 10.

[0030] As Figure 1 、 4 shown in Figures 5, each microporous atomizing sheet 6 includes two vibrating sheets and a piezoelectric element located between the two vibrating sheets. The driving unit includes an input power supply filtering circuit, a power supply control circuit, a width-adjustable rectangular pulse generating circuit, and a power amplification circuit that are electrically connected in sequence. The power supply control circuit is electrically connected to the controller. The power supply control circuit is used to convert a 12V DC voltage into a 1.7MHz alternating current. The width-adjustable rectangular pulse generating circuit is used to generate a 1.7MHz rectangular pulse. The power amplification circuit amplifies the rectangular pulse and applies it to the piezoelectric element to make the piezoelectric element vibrate. Specifically, the vibrating sheet is a thin steel sheet, and the piezoelectric element is a ceramic thin plate.

[0031] Specifically, the power supply control circuit is used to convert a 12V DC voltage into a 1.7MHz alternating current. The width-adjustable rectangular pulse generating circuit is used to generate a 1.7MHz rectangular pulse. The power amplification circuit amplifies the rectangular pulse and applies it to the ceramic thin plate to make the ceramic thin plate vibrate. When the natural vibration frequencies of multiple ceramic thin plates are equal to 1.7MHz, the vibration amplitude of the ceramic thin plate is the largest and is in a resonant state. Correspondingly, the vibration amplitude of the thin steel sheet fixed to the ceramic thin plate is also very large. If the thin steel sheet contacts the accumulated water, the vibration energy of the water molecules increases. When the energy of a part of the liquid water molecules is large enough, they are sprayed into the air to form fog. The fog is blown into the air by the exhaust fan. In this way, by turning the accumulated water into fog and discharging it into the air, water removal is achieved.

[0032] The floor water remover provided by the present invention can quickly remove the accumulated water on outdoor sports fields and courts through the multiple microporous atomization sheets 6 of the atomization pad 5. The height of the atomization pad 5 can be adjusted through the lifting mechanism, so that the present invention is applicable to different depths of accumulated water and can completely remove the accumulated water on the court. At the same time, by setting a liquid sensor, the microporous atomization sheet 6 only works when the corresponding liquid sensor detects liquid, achieving the purpose of energy saving.
