Description

Technical Field

[0001] This utility model relates to the field of pneumatic precipitation equipment technology, specifically an intelligent pneumatic precipitation device for water level control. Background Technology

[0002] Pneumatic dewatering devices are used to lower groundwater levels or drain accumulated water. They are widely used in engineering fields such as building foundation pits, tunnels, and mines. However, existing pneumatic dewatering devices operate continuously once started. When the groundwater level or accumulated water is pumped out and the water surface is lower than the inlet, the device will run idle if left unattended, posing a safety hazard. Furthermore, when the pneumatic dewatering device is placed in the foundation pit or water, it will directly touch the bottom, which can easily damage the bottom inlet. To solve these problems, an intelligent pneumatic dewatering device for water level control is needed.

[0003] An existing pneumatic rainmaking device has the problem that it cannot automatically open and close the device according to the water level and cannot protect the bottom water inlet. Therefore, there is an urgent need for an intelligent pneumatic rainmaking device for water level control. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide an intelligent pneumatic rainmaking device for water level control, so as to solve the problems that existing pneumatic rainmaking devices cannot automatically open and close according to the water level and cannot protect the bottom water inlet.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intelligent pneumatic precipitation device for water level control, comprising a precipitation device body, a limiting sleeve installed on the side wall of the precipitation device body, a limiting rod installed on the inner wall of the limiting sleeve, a float plate installed on the outer wall of the limiting rod, a touch sensor installed at the bottom of the limiting sleeve, an air inlet pipe installed at the top of the precipitation device body, a water outlet pipe installed at the top of the precipitation device body, a vacuum conduit installed at the bottom of the water outlet pipe, a water inlet check valve installed at the bottom of the precipitation device body, a filter screen installed at the bottom of the water inlet check valve, a positioning frame installed on the side wall of the precipitation device body, a buffer rod installed on the inner wall of the positioning frame, and a buffer spring installed on the outer wall of the buffer rod.

[0006] Preferably, the limiting sleeve is symmetrically arranged around the central axis of the main body of the precipitation device, and the float plate is movably connected to the limiting sleeve.

[0007] Preferably, the float plate is slidably connected to the limiting rod, and the float plate is in close contact with the touch sensor.

[0008] Preferably, the air inlet pipe and water outlet pipe are U-shaped, and the diameter of the air inlet pipe and water outlet pipe is larger than the diameter of the vacuum conduit.

[0009] Preferably, the inlet check valve is threadedly connected to the main body of the rainwater receiving device, and the positioning frame is arranged in a rectangular array with the central axis of the main body of the rainwater receiving device as the center.

[0010] Preferably, the buffer rod is movably connected to the positioning frame, and the buffer rod forms a telescopic structure with the positioning frame through a buffer spring.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the setting of a limiting sleeve, limiting rod, float plate and touch sensor, addresses the issue that traditional pneumatic water-falling devices run continuously once started, and when unattended, the equipment will idle when the water level is below the inlet, posing a safety hazard. In contrast, the float plate of this utility model slides downward as the water level drops. When the float plate reaches the bottom and touches the touch sensor, it will shut down the equipment, preventing it from idling and eliminating the need for manual supervision, thus making it more practical.

[0013] 2. The positioning frame, buffer rod, and buffer spring of this utility model prevent the water inlet at the bottom of the rainwater device from hitting the bottom when it is lowered into the pit or water, which could easily cause damage. The buffer rod and buffer spring absorb the impact and leave a distance between the filter screen and the ground to avoid hitting the bottom. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] The embodiments of this utility model will be described below based on its overall structure.

[0021] Please see Figures 1-4 A smart pneumatic rainmaking device for water level control includes a rainmaking device body 1, a limiting sleeve 2 installed on the side wall of the rainmaking device body 1, a limiting rod 3 installed on the inner wall of the limiting sleeve 2, a float 4 installed on the outer wall of the limiting rod 3, and a touch sensor 5 installed at the bottom of the limiting sleeve 2. The limiting sleeve 2 is symmetrically arranged around the central axis of the rainmaking device body 1, and the float 4 is movably connected to the limiting sleeve 2, slidably connected to the limiting rod 3, and tightly fitted to the touch sensor 5. With the limiting sleeve 2, limiting rod 3, float 4, and touch sensor 5, traditional pneumatic rainmaking devices run continuously after startup. When unattended, the device will idle when the water level is below the inlet, posing a safety hazard. In contrast, the float 4 of this invention slides downwards as the water level drops. When the float 4 reaches the bottom and touches the touch sensor 5, it shuts down the device, preventing idle operation and eliminating the need for manual supervision, thus enhancing its practicality.

[0022] Please see Figures 1-4 An intelligent pneumatic rainmaking device for water level control is disclosed. The device body 1 has an air inlet pipe 6 at its top, a water outlet pipe 7 at its top, a vacuum conduit 8 at its bottom, a water inlet check valve 9 at its bottom, a filter screen 10 at its bottom, a positioning frame 11 on its side wall, a buffer rod 12 on the inner wall of the positioning frame 11, and a buffer spring 13 on the outer wall of the buffer rod 12. The air inlet pipe 6 and the water outlet pipe 7 are U-shaped, and their diameters are larger than the diameter of the vacuum conduit 8. The water check valve 9 is threadedly connected to the main body 1 of the dewatering device. The positioning frame 11 is arranged in a rectangular array with the central axis of the main body 1 of the dewatering device as the center. The buffer rod 12 is movably connected to the positioning frame 11, and the buffer rod 12 forms a telescopic structure with the positioning frame 11 through the buffer spring 13. When the main body 1 of the dewatering device is lowered into the pit or water through the positioning frame 11, buffer rod 12 and buffer spring 13, the water inlet at the bottom of the main body 1 of the dewatering device will hit the bottom and be easily damaged. The buffer rod 12 is set to absorb the impact through the buffer spring 13, and a distance is reserved between the filter screen 10 and the ground to avoid hitting the bottom.

[0023] Working principle: In use, first move the device to the desired location, then drill a hole in the foundation pit. Connect the air inlet pipe 6 to the external air compressor. Place the main body 1 of the dewatering device into the drilled hole in the foundation pit, ensuring the water level is parallel to the lowest point of the float 4. When the main body 1 of the dewatering device is lowered into the hole in the foundation pit, the water inlet at the bottom of the device will hit the bottom, potentially causing damage. The buffer rod 12, with its buffer spring 13, absorbs this impact and provides a distance between the filter screen 10 and the ground, preventing impact. The float 4 rises to the top due to buoyancy, and then the external air compressor is activated to pump the water inlet... Air is pressurized and supplied through the air pipe 6 and ejected from the water outlet pipe 7. When the airflow passes above the vacuum duct 8, a Bernoulli effect is generated, creating a negative pressure above the vacuum duct 8. This draws water from the bottom of the main body 1 of the rain-driving device and ejects it from the water outlet pipe 7 along with the airflow. As water is continuously drawn out, the water level decreases, and the float 4 also decreases with the water level. When the float 4 reaches the bottom, it contacts the touch sensor 5, thereby transmitting a signal to shut down the external air compressor and stop its operation, preventing the equipment from running dry due to excessively low water levels. This completes the use of the device. Any content not described in detail in this specification is prior art known to those skilled in the art.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
