Description

Technical Field

[0001] This utility model relates to the field of leak-sealing construction equipment technology, specifically an adjustable flow cement-based leak-sealing agent spraying device. Background Technology

[0002] With the continuous development of construction technology and the ongoing expansion of construction projects, problems such as leakage and cracks often occur in concrete structures, tunnel structures, and underground construction projects, requiring the rapid and efficient use of cement-based sealants for sealing and repair. The existing spraying device for alkali-activated cement shotcrete in tunnels (Publication No.: CN218862623U) has the following drawbacks and needs further improvement.

[0003] Traditional equipment cannot adjust the flow rate of the sealant, which can easily lead to excessive spraying of sealant during construction, resulting in material waste and increased construction costs.

[0004] On the other hand, if the sealant is not sprayed sufficiently, it will not be able to effectively fill cracks or voids, resulting in poor sealing effect and even requiring repeated construction, which seriously affects construction efficiency. Summary of the Invention

[0005] The main objective of this invention is to provide an adjustable flow rate cement-based sealant spraying device, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an adjustable flow rate cement-based sealant spraying device, wherein a pressurized pneumatic pump is provided on one side of the storage tank, a mixing device is connected below the storage tank, a drive motor is provided on one side of the mixing device, a pressure gauge is provided above the drive motor, a pressure sensor is also provided above the drive motor, a connecting hose is provided on one side of the mixing device, a pushing device is connected to the other side of the connecting hose, a regulating valve is also connected to one side of the pushing device, a power module is connected to the other side of the pushing device, a water pipe of the regulating valve is connected to the nozzle, a flow meter is provided on the outside of the nozzle, an electric regulating valve is also provided on the outside of the nozzle, and a nozzle is provided at the top of the nozzle.

[0007] Preferably, the bottom of the storage tank is provided with a discharge port with an inner diameter of 40-60mm, and the discharge port is connected to the inlet of the mixing device by a threaded connection.

[0008] Preferably, the drive motor and the mixing device are connected by a coupling, and the coupling adopts a flexible coupling structure.

[0009] Preferably, the connecting hose is a pressure-resistant reinforced hose with an inner diameter of 15-20mm, and quick connectors are provided at the connection points between the connecting hose and the mixing device and the pushing device.

[0010] Preferably, the regulating valve and the nozzle are connected by a threaded pipe joint, and the pipe diameter at the connection is 10-15mm.

[0011] Preferably, the nozzle is a detachable nozzle, which is fixed to the top of the nozzle head by a threaded connection, and the nozzle outlet diameter is 3-8mm.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This equipment, by incorporating regulating valves, flow meters, and electrically controlled regulating valves, achieves precise control of the flow rate of cement-based sealant, effectively preventing over- or under-application of sealant during spraying. Specifically, the regulating valves and electrically controlled regulating valves adjust the pipeline opening in real time, while the flow meter displays the sealant flow rate in real time, ensuring accurate delivery of the sealant to the construction area.

[0014] This equipment incorporates pressure gauges and sensors to monitor pipeline pressure in real time during the sealing agent delivery process. The pushing device and drive motor provide stable and reliable power output, ensuring consistent sealing agent delivery and reducing reliance on operator experience. The design of the nozzles and spray heads improves the uniformity and precision of the application process, resulting in consistent and high-quality sealing work. Attached Figure Description

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0021] Please see Figure 1-2 This utility model provides a technical solution:

[0022] An adjustable flow cement-based sealant spraying device includes a keyhole 2 at the front of the main body 1, an input device 3 at the front of the main body 1, a hinge 4 at the front of the main body 1, an output interface 5 at the top of the main body 1, a battery 6 inside the main body 1, a central control system module 7 inside the main body 1, a communication module 8 inside the main body 1, a fault detection module 9 inside the main body 1, a photosensitive sensor 10 inside the main body 1, an energy efficiency controller 11 inside the main body 1, a timer 12 inside the main body 1, and a program control module 13 inside the main body 1.

[0023] The storage tank and mixing device are connected by threads, with the mixing device fixed to the bottom of the storage tank, ensuring a sealed connection and facilitating disassembly and maintenance. A pressurized pneumatic pump is located on one side of the storage tank and connects to the tank's interior via a side interface, used to apply pressure to the cement-based sealant within. The mixing device stirs and mixes the sealant in the storage tank, preventing sedimentation and ensuring uniform composition. A regulating valve, flow meter, and electrically adjustable valve are sequentially installed on the storage tank's outlet pipeline. The regulating valve allows manual adjustment of the sealant flow rate through the pipeline, the flow meter measures the flow rate in real time, and the electrically adjustable valve controls the valve opening via an electrical signal to precisely regulate the flow rate. One end of a pressure-resistant reinforced hose is connected to the outlet of the pressurized pneumatic pump via a quick-connect coupling, and the other end is connected to a nozzle via a quick-connect coupling. The nozzle features a detachable design, secured to the hose end with a threaded connection for easy disassembly, replacement, and cleaning. Pressure-resistant reinforced hoses have high pressure resistance and good flexibility. They can be connected to relevant components via quick couplings to improve the sealing of the connection and facilitate the installation and relocation of equipment.

[0024] In use, the pre-prepared cement-based sealant is poured into the storage tank, and the mixing device is started to stir the sealant, keeping the slurry uniformly suspended. Then, the pressurized pneumatic pump is started, which applies pressure to the storage tank and pushes the slurry from the storage tank through the mixing device into the outlet pipeline. The slurry passes through the regulating valve, flow meter, and electric regulating valve in sequence, enters the pressure-resistant reinforced hose, and is finally sprayed out through the nozzle. The cement-based sealant slurry is sprayed at high speed through nozzle 15 onto the area to be sealed, filling cracks or holes, and forming a solid sealing layer after solidification.

[0025] During spraying, the operator can first set an approximate flow range by adjusting the valve opening, then observe the flow meter reading, and make fine adjustments as needed by controlling the opening and closing of the electric regulating valve to achieve real-time control of the spray flow. If the flow rate is found to be too high or too low, the aforementioned valve can be adjusted promptly, using the feedback data provided by the flow meter to ensure the accuracy of the adjustment. After the operation is completed, the electric regulating valve and the regulating valve are closed to stop the slurry flow. Because the nozzle is detachable, the operator can easily remove it for cleaning, preventing residual slurry from solidifying and clogging the nozzle, thus ensuring that the device is in good condition for the next use.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
