Description

Technical Field

[0001] This utility model relates to the field of engineering testing technology, specifically to a device for detecting hollow plastering in civil construction. Background Technology

[0002] In construction projects, plastering is often required to protect walls, improve their functionality, and enhance their appearance. However, hollow areas occur when plastering is uneven, creating air gaps between the plaster layer and the wall surface. These air gaps can negatively impact the wall's aesthetics, reduce structural durability, and pose safety hazards. Therefore, after plastering, a hollow area detection device is needed to inspect for hollow areas, and the plastering process must be repeated.

[0003] Currently, most existing hollow area detection methods employ the following techniques to achieve their desired results: The tapping method is one of the most common methods for detecting hollow spots. Inspectors use a small hammer to gently tap the wall and observe changes in the sound to determine if hollow spots are present. Ultrasonic testing uses ultrasonic equipment to scan the wall surface. When ultrasonic waves propagate in different media, they will produce reflection, refraction and scattering when they encounter defects such as hollow areas. Hollow areas can be identified by analyzing the characteristics of the reflected waves. Infrared thermal imaging identifies hollow areas by detecting the temperature distribution on the wall surface. Because hollow areas contain air, and air has different thermal conductivity than solid walls, the rate of temperature change in hollow areas differs from that of the surrounding solid walls when the ambient temperature changes, typically exhibiting different temperature characteristics.

[0004] However, conventional devices used for detecting hollow areas still have the following technical problems in practical applications: Conventional hollow wall detection devices require marking the wall after detecting hollow areas. However, marking the wall involves putting down the detection tool, marking the wall with the marking tool, and then picking up the detection tool again to continue the detection. This process of putting down and picking up the tool is time-consuming, and the separate operations of putting down and picking up the tool can easily lead to misalignment of the markings, thus affecting work efficiency.

[0005] Therefore, there is an urgent need for a device to detect hollow areas in plastering during civil construction, in order to solve the problem of low efficiency of conventional hollow area detection devices. Utility Model Content

[0006] This utility model addresses the shortcomings of existing technologies by providing a device for detecting hollow areas in plastering during civil construction, thereby solving the problem of low working efficiency of conventional hollow area detection devices.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A device for detecting hollow plastering in civil construction includes a backpack, a three-section damping telescopic rod, an ultrasonic testing instrument body, and a marking mechanism. The backpack contains a power supply and a paint container. The three-section damping telescopic rod is electrically connected to the power supply. The moving end of the three-section damping telescopic rod is equipped with the ultrasonic testing instrument body for detection. The marking mechanism includes a water pump, a drain pipe, a guide pipe, and a nozzle. The water pump is installed on the side of the three-section damping telescopic rod and is electrically connected to the power supply. The input end of the water pump is connected to the paint container through the drain pipe, and the output end is connected to the nozzle located at the moving end of the three-section damping telescopic rod through the guide pipe. The three-section damping telescopic rod is used to drive the ultrasonic testing instrument body and the nozzle to move synchronously.

[0008] To optimize the above technical solution, the specific measures also include: Furthermore, a handle is fixedly connected to the bottom of the three-section damping telescopic rod.

[0009] Furthermore, the surface of the grip is provided with a control switch, which is electrically connected to the three-section damping telescopic rod and the water pump respectively, and is used to control the telescopic movement of the three-section damping telescopic rod or to control the start and stop of the water pump.

[0010] Furthermore, the outer side of the grip is provided with anti-slip texture.

[0011] Furthermore, the side wall of the three-section damping telescopic rod is provided with a display panel, which is electrically connected to the ultrasonic detector body.

[0012] Furthermore, the guide tube is installed on the surface of the three-section damping telescopic rod through a limiting mechanism. The limiting mechanism includes four limiting blocks, two of which are fixed at intervals to the fixed section of the three-section damping telescopic rod, and the other two limiting blocks are fixedly connected to the two movable sections of the three-section damping telescopic rod respectively. Each limiting block is provided with a through hole that runs vertically through it, and the through hole is used for the guide tube to pass through.

[0013] Furthermore, a fixed base is fixedly connected to the top of the ultrasonic detector body, and the nozzle is fixedly connected to the moving end of the three-section damping telescopic rod through the fixed base.

[0014] Furthermore, a conduit is connected between the backpack and the three-section damping telescopic rod for cable routing.

[0015] The beneficial effects of this utility model are: This invention, through the design of a backpack, a three-section damping telescopic rod, an ultrasonic detector body, and a marking mechanism, allows operators to control and perform detection operations on different locations on walls of varying heights using the three-section damping telescopic rod in conjunction with the ultrasonic detector body. This improves the applicability of the device. The three-section damping telescopic rod, in conjunction with the marking mechanism, allows for convenient marking of corresponding hollow locations without the need to set down the device and use additional marking tools, thus solving the problem of low working efficiency in conventional hollow detection devices.

[0016] In use, this invention allows the detection end of the ultrasonic detector to be placed close to the wall for inspection. When the ultrasonic detector detects hollow areas in the wall, the water pump of the marking mechanism can be started. The water pump draws paint from the paint container through the diversion pipe and pumps it to the nozzle through the guide pipe. The paint is then sprayed directly onto the wall through the nozzle, quickly marking the hollow areas. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings.

[0020] As attached Figure 1 and attached Figure 2As shown in the figure, a plastering hollow detection device for civil construction according to an embodiment of the present invention includes a backpack 1, a three-section damping telescopic rod 2, an ultrasonic detector body 5, and a marking mechanism. The backpack 1 is equipped with a power supply and a paint container 101. The three-section damping telescopic rod 2 is electrically connected to the power supply. The ultrasonic detector body 5 for detection is installed at the moving end of the three-section damping telescopic rod 2. The marking mechanism includes a water pump 4, a drain pipe 401, a guide pipe 402, and a nozzle 403. The water pump 4 is installed on the side of the three-section damping telescopic rod 2 and is electrically connected to the power supply. The input end of the water pump 4 is connected to the paint container 101 through the drain pipe 401, and the output end is connected to the nozzle 403 set at the moving end of the three-section damping telescopic rod 2 through the guide pipe 402. The three-section damping telescopic rod 2 is used to drive the ultrasonic detector body 5 and the nozzle 403 to move synchronously.

[0021] This invention, through the configuration of a backpack 1, a three-section damping telescopic rod 2, an ultrasonic detector body 5, and a marking mechanism, allows for the use of the three-section damping telescopic rod 2 in conjunction with the ultrasonic detector body 5. Operators can control the device to perform detection operations at different locations on walls of varying heights, improving its applicability. Furthermore, the three-section damping telescopic rod 2, combined with the marking mechanism, allows for convenient marking of corresponding hollow areas without the need to set down the device and use additional marking tools, thus solving the problem of low efficiency in conventional hollow detection devices.

[0022] In use, the ultrasonic detector body 5 can be placed close to the wall to detect the wall. When the staff detects a hollow area in the wall through the ultrasonic detector body 5, the water pump 4 of the marking mechanism can be started. The water pump 4 draws paint from the paint container 101 through the diversion pipe 401 and pumps it to the nozzle 403 through the guide pipe 402. The paint is then sprayed directly onto the wall through the nozzle 403 to mark the hollow area.

[0023] In the above scheme, the paint container 101 can also be installed on the surface of the backpack 1. The paint container 101 stores paint for marking hollow areas, providing a paint source for the marking operation. The backpack 1 is used to carry and store electrical equipment such as power supply equipment, including an electronic control unit, power supply, and PLC controller, providing power and control support for the entire device, and carrying the paint container 101 to facilitate the carrying, movement, and use of the equipment. One end of the drainage pipe 401 is fixedly connected to the bottom surface of the paint container 101, and the other end is fixedly connected to the input end of the water pump 4, for guiding the paint in the paint container 101 to the water pump 4. One end of the guide pipe 402 is fixedly connected to the output end of the water pump 4, and the other end is fixedly connected to the nozzle 403, for guiding the paint pumped out by the water pump 4 to the nozzle 403.

[0024] In one specific embodiment based on the above, a handle 3 is fixedly connected to the bottom of the three-section damping telescopic rod 2. This allows the operator to easily grip the three-section damping telescopic rod 2 to control its position, as well as the ultrasonic testing instrument body 5 and the nozzle 403. In this design, the water pump 4 can be installed on the side of the handle 3.

[0025] The handle 3 is equipped with a control switch 6, which is electrically connected to the three-section damping telescopic rod 2 and the water pump 4. The control switch 6 controls the extension and retraction of the three-section damping telescopic rod 2 and the start / stop of the water pump 4. This allows operators to easily control the three-section damping telescopic rod 2 or the water pump 4 from the handle 3. Specifically, when a hollow area in the wall is detected, the water pump 4 is started via the control switch 6, drawing paint from the paint container 101 through the drainage pipe 401 and pumping it to the nozzle 403 through the guide pipe 402, thus marking the hollow area. In this design, the control switch 6 can also control the start / stop of the ultrasonic detector body 5, facilitating operator operation. In this design, different start / stop buttons can be configured on the control switch 6 according to actual needs to fulfill different operational requirements.

[0026] The outer side of the aforementioned grip 3 is provided with anti-slip texture.

[0027] In another specific embodiment based on the above, a display panel 7 is provided on the side wall of the three-section damping telescopic rod 2, and the display panel 7 is electrically connected to the ultrasonic detector body 5. In this solution, when the ultrasonic detector body 5 detects a hollow area in the wall, it displays the information through the display panel 7. Specifically, a PLC controller is also provided on the inside of the backpack 1, and the display panel 7 is electrically connected to the ultrasonic detector body 5 via the PLC controller. When the ultrasonic detector body 5 detects a hollow area in the wall, it transmits the detection data to the PLC controller, which then transmits the data to the display panel 7. After receiving the data, the display panel 7 displays the detection results, such as whether a hollow area exists in the wall.

[0028] As attached Figure 3 and attached Figure 4As shown, in another specific embodiment based on the above, the guide tube 402 is installed on the surface of the three-section damping telescopic rod 2 by a limiting mechanism. The limiting mechanism includes four limiting blocks 201, two of which are fixed at intervals to the fixed section of the three-section damping telescopic rod 2, and the other two are fixedly connected to the two movable sections of the three-section damping telescopic rod 2 respectively. Each limiting block 201 has a through hole that extends vertically through it, allowing the guide tube 402 to pass through. Thus, by setting the limiting blocks 201, the guide tube 402 can be limited without affecting its movement. In this solution, a guide tube 402 with sufficient movement allowance is reserved between the two limiting blocks 201 fixed to the fixed section of the three-section damping telescopic rod 2 to accommodate the extension and retraction of the three-section damping telescopic rod 2. In the above scheme, the guide tube 402 can have sufficient room for movement between each limiting block 201. At the same time, the guide tube 402 can also be used with a telescopic hose as needed to meet the telescopic requirements.

[0029] In another specific embodiment based on the above, a fixing base 501 is fixedly connected to the top of the ultrasonic detector body 5, and the nozzle 403 is fixedly connected to the moving end of the three-section damping telescopic rod 2 through the fixing base 501. In this way, the nozzle 403 is fixed by the fixing base 501, so that the nozzle 403 can accurately mark the detected hollow areas.

[0030] In another specific embodiment based on the above, a conduit 8 connects the backpack 1 and the three-section damping telescopic rod 2, and the conduit 8 is used for wiring. In this solution, the aforementioned three-section damping telescopic rod 2, display panel 7, control switch 6, water pump 4, ultrasonic detector body 5, etc., can all be connected by flexible wires passing through the conduit 8 to complete the corresponding electrical connections. The conduit 8 provides a channel for the wiring and plays a role in protecting the wiring.

[0031] One specific embodiment of this utility model is as follows: The operator can hold the handle 3 and drive the three-section damping telescopic rod 2 to control the position of the ultrasonic detector body 5, so that the detection end of the ultrasonic detector body 5 is close to the wall. The operator can start the ultrasonic detector body 5 to detect the wall by controlling the control switch 6. When the ultrasonic detector body 5 detects a hollow area in the wall, it will be displayed on the display panel 7. At this time, the operator can start the water pump 4 by controlling the control switch 6. The water pump 4 draws paint from the paint container 101 through the diversion pipe 401 and pumps it to the nozzle 403 through the guide pipe 402. The paint is sprayed directly onto the wall through the nozzle 403 to mark the hollow area. There is no need to put down the device and use a separate marking tool, which solves the problem of low working efficiency of conventional hollow detection devices.

[0032] When in use, the position of the ultrasonic detector body 5 can be adjusted by the three-section damping telescopic rod 2, so that the device can perform detection and marking operations on different positions of walls at different heights, making the device highly applicable and convenient.
