Description

Technical Field

[0001] The present invention relates to the technical field of water level gauges, and particularly to a water level monitor. Background Art

[0002] The problem of rural water supply in China is one of the serious existing problems in China. The main problems in rural water supply in China include long water intake distance, lack of water volume, unqualified water quality, serious water pollution, and backward water supply facilities, which greatly affect the physical and mental health of rural people in China. Therefore, rural water supply is of crucial importance. In the rural water supply system, the water level monitoring of the water supply pool is particularly important.

[0003] In order to reduce pollution, the existing rural water supply pools are usually closed. The monitoring of rural water supply pools mainly uses pressure sensors and ultrasonic technologies. For the method of pressure sensors, the equipment needs to work in an environment of immersion and high water pressure for a long time, resulting in high equipment costs, difficult installation and maintenance. At the same time, ultrasonic signals are prone to ranging distortion in a closed or semi-closed environment. At the same time, sediment is likely to accumulate at the bottom of rural water supply pools, which will not only affect the water storage capacity of the pools over time, thereby affecting the water level monitoring accuracy, but also pollute the water body. For closed pools, it is inconvenient to clean. Summary of the Invention

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0030] As Figures 1-8As shown, a water level monitor includes a pool body 1, an axial hole is opened at the top of the pool body 1, a guide shaft 2 passing through the axial hole is rotatably installed inside the pool body 1, a floating mechanism 6 is sleeved on the outer side of the guide shaft 2, the floating mechanism 6 can float on the water surface, the floating mechanism 6 can absorb and spray water, and a water level meter 5 is installed on the top of the floating mechanism 6, which can detect the distance between the water level meter 5 and the top of the pool body 1.

[0031] The floating mechanism 6 and the guide shaft 2 are placed in the pool body 1 in advance, and then the water level meter 5 is installed on the floating mechanism 6. The installation is convenient. When there is water in the pool body 1, the floating mechanism 6 floats up, and the water level meter 5 measures the distance from it to the top of the pool body 1. Since the distance between the water level meter 5 and the water surface is fixed, the liquid level height can be accurately calculated by the overall height of the pool body 1. At the same time, under the restriction of the floating mechanism 6 and the guide shaft 2, the water level meter 5 will not shake due to the movement of the water surface, thereby improving the stability of the monitoring results.

[0032] When the pool body 1 needs to be cleaned, the floating mechanism 6 is controlled to absorb water, and then the water in the pool body 1 is released. The gravity of the water absorbed by the floating mechanism 6 increases, and it will fall stably to the bottom of the pool body 1. Then the guide shaft 2 is controlled to rotate, and the guide shaft 2 drives the floating mechanism 6 to rotate. The floating mechanism 6 cleans the top of the pool body 1. At the same time, the floating mechanism 6 is controlled to spray water to flush the bottom of the pool body 1, and then the pool body 1 can be automatically cleaned, which can prevent the detection accuracy from being affected by excessive sedimentation. At the same time, no manual cleaning is required, and it is more suitable for use in rural water supply pools. At the same time, the amount of water stored in the floating mechanism 6 can be accurately controlled to save water resources.

[0033] like Figures 3-6 As shown, in some embodiments, the floating mechanism 6 includes a guide sleeve 61 that is sleeved on the outside of the guide shaft 2, and a mounting float plate 62 is provided in an annular manner on the outside of the guide sleeve 61. A storage cavity is provided inside the mounting float plate 62, and an automatically sliding extrusion plate 65 is slidably connected to the inside of the storage cavity. A water inlet hole 614 is linearly provided at the bottom of the mounting float plate 62, and a groove is provided at one end of the water inlet hole 614 located inside the storage cavity. A valve plug 615 is inserted into the water inlet hole 614, and a valve plate 616 inserted in the groove is provided on the top of the valve plug 615, and a tension spring 617 is provided between the valve plate 616 and the groove, and a one-way drainage pipe 618 is linearly provided on the outside of the mounting float plate 62.

[0034] The hollow design of the installation float 62 allows the installation float 62 to float on the water surface. Under the action of the guide sleeve 61 and the guide shaft 2, the shaking of the water surface can be slowed down, thereby improving the detection stability.

[0035] During normal detection of the device, the pressing plate 65 presses on the top of the valve plate 616. The pressing plate 65 restricts the opening of the valve plate 616, thereby restricting the water inflow through the water inlet hole 614 and ensuring that the installation floating plate 62 can float stably on the water surface.

[0036] When it is necessary to clean the bottom of the pool body 1, control the pressing plate 65 to move away from the valve plate 616. The pressing plate 65 enables the interior of the storage cavity to be fully filled with water. At this time, under the action of the gravity of the device, the valve plate 616 and the valve plug 615 rise relative to the water inlet hole 614, and the water inlet hole 614 fills the interior of the storage cavity with water. When the amount inside the storage cavity is saturated, at this time, the pool body 1 discharges water, and the water inlet hole 614 will not drain water under the action of the tension spring 617 and the valve plate 616, ensuring stable water storage.

[0037] When it is necessary to spray water, control the pressing plate 65 to slide. The pressing plate 65 sprays water through the one-way drain pipe 618, thereby being able to wash the inner bottom of the pool body 1. At the same time, the pressing plate 65 can further restrict the opening of the valve plate 616 to ensure stable drainage.

[0038] As Figure 6 shown, in some embodiments, the radius of the valve plate 616 is greater than the radius of the valve plug 615, and both the water inlet hole 614 and the valve plug 615 are designed in a conical shape.

[0039] Through this design, the water inlet hole 614 can be better sealed, and at the same time, it is ensured that the water inlet hole 614 will not drain water.

[0040] As Figure 3 shown, in some embodiments, a sliding groove 66 is formed on the inner wall of the storage cavity. A counterweight block 67 is slidably connected inside the sliding groove 66. The outside of the counterweight block 67 is hinged with a top rod 68 that is hinged to the pressing plate 65.

[0041] The guide shaft 2 drives the guide sleeve 61 to rotate. The guide sleeve 61 drives the installation floating plate 62 to rotate. The installation floating plate 62 drives the counterweight block 67 to rotate. The counterweight block 67 slides along the sliding groove 66 under the action of centrifugal force. The counterweight block 67 pushes the pressing plate 65 to slide through the top rod 68. The pressing plate 65 can automatically squeeze out the water in the storage cavity without an additional driving mechanism, and can automatically drain water while cleaning, with a compact structure. When the counterweight block 67 is in the initial position, the top rod 68 is inclined between the counterweight block 67 and the pressing plate 65 to ensure that the top rod 68 does not affect the sliding of the counterweight block 67.

[0042] As Figure 4As shown, in some embodiments, a top spring 69 is installed inside the sliding groove 66, a transmission groove is formed inside the guide sleeve 61, a magnetic plate 610 capable of attracting the counterweight 67 is slidably connected inside the transmission groove, a thrust spring 611 is arranged between the magnetic plate 610 and the transmission groove, a sliding hole is formed in the inner wall of the guide sleeve 61, and a sliding rod 612 is slidably connected inside the sliding hole. The sliding rod 612 is drivingly connected to the magnetic plate 610 through a transmission rope.

[0043] When it is necessary to open the water inlet hole 614, control the sliding of the sliding rod 612. The sliding rod 612 drives the magnetic plate 610 to slide through the transmission rope. The magnetic plate 610 drives the counterweight 67 to slide towards the guide sleeve 61 by magnetic force. At this time, the counterweight 67 drives the pressing plate 65 away from the valve plate 616 through the ejector rod 68, the valve plate 616 can be opened, the water inlet hole 614 can let water in, and the control is stable.

[0044] As Figure 7 、 Figure 8 As shown, in some embodiments, the guide shaft 2 includes a shaft body 21 rotatably installed inside the pool body 1. A guide groove 22 is formed on the outer side of the shaft body 21. An air pressure groove 23 is formed inside the guide groove 22. A clamping plate 24 capable of pushing the sliding rod 612 to slide is slidably connected inside the air pressure groove 23. A pressure bladder 25 is arranged at the top of the shaft body 21. The pressure bladder 25 is connected to the air pressure groove 23 through an air hole. A return spring 613 is arranged between the sliding rod 612 and the inner wall of the sliding hole.

[0045] Using an external heavy object to press on the pressure bladder 25, the pressure bladder 25 pushes the clamping plate 24 to slide through the air hole and the air pressure groove 23. The clamping plate 24 pushes the sliding rod 612 to slide. The sliding rod 612 drives the magnetic plate 610 to slide through the transmission rope. The magnetic plate 610 drives the counterweight 67 to slide towards the guide sleeve 61 by magnetic force. At this time, the counterweight 67 drives the pressing plate 65 away from the valve plate 616 through the ejector rod 68, the valve plate 616 can be opened, the water inlet hole 614 can let water in. After the water inlet is completed, remove the heavy object. At this time, under the action of the return spring 613, the sliding rod 612 resets, the sliding rod 612 drives the clamping plate 24 to reset. At the same time, under the action of the thrust spring 611, the magnetic plate 610 resets. At this time, under the action of the top spring 69, the counterweight 67 resets. The counterweight 67 pushes the pressing plate 65 to reset through the ejector rod 68. The pressing plate 65 presses on the valve plate 616 to prevent the valve plate 616 from opening, and can further limit the drainage of the water inlet hole 614. The control is stable, no electric device is required for control, and the maintenance is convenient.

[0046] As Figure 4 As shown, in some embodiments, a guide protrusion 619 is arranged on the inner wall of the guide sleeve 61. The guide protrusion 619 is slidably connected in the guide groove 22. By the combined use of the guide protrusion 619 and the guide groove 22, while the guide shaft 2 can stably drive the floating mechanism 6 to rotate, the stability of the floating mechanism 6 can be further ensured.

[0047] As Figure 2 shown, in some embodiments, a cleaning plate 63 is annularly arranged on the outer side of the guide sleeve 61, a cleaning brush 64 is arranged at the bottom of the cleaning plate 63, and the cleaning plate 63 and the mounting floating plate 62 are cross-designed.

[0048] When the floating mechanism 6 descends to the bottom and needs to be cleaned, the guide shaft 2 drives the guide sleeve 61 to rotate, the guide sleeve 61 drives the mounting floating plate 62 and the cleaning plate 63 to rotate, and the cleaning plate 63 brushes the bottom of the pool body 1 through the cleaning brush 64 at the bottom. Due to the cross-design of the cleaning plate 63 and the mounting floating plate 62, after the cleaning brush 64 finishes brushing, the mounting floating plate 62 sprays water through the one-way drain pipe 618, and the one-way drain pipe 618 flushes the position that has been cleaned, which can ensure that the dirt cleaned out can be discharged smoothly and the cleaning effect is good.

[0049] As Figure 3 shown, in some embodiments, one end of the one-way drain pipe 618 away from the mounting floating plate 62 is designed to be inclined downward. Through this design, the sprayed water flow can be sprayed towards the inner bottom of the pool body 1, and the flushing effect is good.

[0050] As Figure 1 shown, in some embodiments, a sealing bearing 3 is arranged between the guide shaft 2 and the shaft hole, and a driving handle 4 is arranged at the top of the guide shaft 2.

[0051] Through the design of the sealing bearing 3, it can prevent external pollutants from entering the pool body 1. When the guide shaft 2 needs to be rotated, by rotating the driving handle 4, the guide shaft 2 can be driven to rotate. Since the rural water supply pools are not concentrated, this driving method is convenient, better than motor driving, and can also save maintenance costs.

[0052] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
