Description

Technical Field

[0001] The utility model belongs to the field of building waterproof detection, in particular to a portable building waterproof sealing negative pressure detection device. Background Art

[0002] Water seepage in buildings is a common problem that can arise from a variety of causes and can affect the structural integrity of a building as well as the health and comfort of its occupants. If a building's waterproofing (such as that on the roof, basement or external walls) is damaged or deteriorates, it can allow moisture to penetrate the building interior.

[0003] The Chinese utility model patent with announcement number CN219391266U discloses a building waterproof sealing negative pressure detection device, including a detection cover, a water pump and a vacuum pump. The detection cover is composed of an outer cover body and an inner cover body inside the outer cover body. A negative pressure chamber is provided in the peripheral side wall of the outer cover body. A negative pressure pipe connected to the negative pressure chamber is fixedly connected to one side of the outer cover body. A pressure water chamber is provided inside the inner cover body. One end of the inner cover body is fixedly connected to a water inlet pipe connected to the pressure water chamber. Through the mutual cooperation between the outer cover body and the inner cover body, the vacuum pump can generate negative pressure at the opening of the outer cover body, firmly adsorb the outer cover body on the wall, and pump a certain amount of water into the pressure water chamber by the water pump and continuously pressurize the water, so as to detect the waterproof sealing performance of the wall at that location.

[0004] Regarding the above-mentioned related technologies, the inventors believe that the following defects exist: when the negative pressure detection device is in use, due to the lack of a sealing device for the contact surface between the outer cover and the building, water may leak out due to insufficient sealing when water is injected, thereby affecting the accuracy of the detection results.

[0005] Therefore, those skilled in the art have proposed a portable building waterproof sealing negative pressure detection device to solve the problems raised in the background art. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a portable building waterproof and sealed negative pressure detection device to solve the problem that the negative pressure detection device in the existing technology lacks a sealing device for the contact surface between the outer cover and the building during use, and water may leak out due to insufficient sealing when water is injected, thereby affecting the accuracy of the detection results.

[0007] A portable building waterproof seal negative pressure detection device includes a base, a through slot provided in the base, and a hollow column slidably connected to the through slot. The hollow column is provided with a detection component for detecting the sealing of the building, and the base is provided with a sealing component for sealing the building ground structure.

[0008] The detection component includes a water cylinder fixedly connected to the upper end of the hollow column, a water inlet pipe fixedly connected to the upper end of the water cylinder, a valve installed on the water inlet pipe and the water cylinder, a circular ring fixedly connected to the lower end of the hollow column and a limit cover fixedly sleeved on the surface of the circular ring.

[0009] Preferably, the sealing assembly includes a cylinder mounted on the base, a delivery pump mounted on the base, a feed pipe mounted on the input end of the delivery pump, and a discharge pipe mounted on the output end of the delivery pump. The discharge pipe passes through the base and is fixedly connected to the upper end of the limit cover, and one end of the feed pipe is fixedly connected to a side wall of the cylinder.

[0010] Preferably, universal wheels are installed at the four corners of the bottom of the base, and a handle is installed on the base.

[0011] Through the above technical solution, when in use, the hollow column is slid in the base so that the circular ring and the limit cover at the lower end of the hollow column are in contact with the ground, and then the sealant is poured into the cylinder. The delivery pump can be started to use the feed pipe and the discharge pipe to deliver the sealant to the limit cover. After the sealant contacts the ground, it is located between the limit cover and the circular ring. After the sealant solidifies, the limit cover will be in sealed contact with the ground, thereby improving the airtightness of subsequent inspection work. The outer diameter of the water cylinder is consistent with the inner diameter of the hollow column. During inspection, the water cylinder is filled with water through the water inlet pipe, the valve on the water cylinder is opened, and the valve on the water inlet pipe is closed. At this time, water will fall between the circular ring and the ground. After waiting for the water level in the water cylinder to stabilize, the reading of the scale bar is recorded. After a period of time, the reading of the scale bar on the surface of the water cylinder is recorded again. In this way, it is possible to observe whether the area is leaking. The accuracy of the building ground waterproofing work can be improved by setting the sealant.

[0012] Preferably, a mounting plate is fixedly connected inside the cylinder, a driving motor is mounted on the mounting plate, a rotating shaft is mounted on the output end of the driving motor, and two symmetrically arranged scrapers are fixedly connected to the surface of the rotating shaft.

[0013] Preferably, a boss is fixedly connected to the inner bottom surface of the cylinder, the boss is located at the feed pipe of the side wall of the cylinder, and the scraper matches the boss.

[0014] Preferably, a scale bar is provided on the surface of the water container.

[0015] Preferably, a slide groove is opened on one side of the through groove, a slider is slidably connected in the slide groove, a cylinder is installed on the upper surface of the base, and the output end of the cylinder is installed together with the upper surface of the slider.

[0016] Preferably, a vacuum pump is installed on the upper surface of the base, a connecting pipe is installed at the input end of the vacuum pump, and one end of the connecting pipe is fixedly connected to the side wall of the water container.

[0017] Through the above technical solution, when in use, the driving motor can be started to drive the rotating shaft and the scraper on it to rotate, so as to facilitate the discharge of the sealant in the cylinder. By closing the valve on the water inlet pipe, opening the valve on the water cylinder, and starting the vacuum pump, the water cylinder can be vacuumed, thereby achieving the effect of increasing the negative pressure in the water cylinder. If there are gaps in the ground that can seep water, the speed of water seepage can be accelerated, saving the waiting time of the staff. By starting the cylinder, the slider and the hollow column on it can be driven to move downward to contact the ground, thereby improving the stability of the contact between the limit cover and the ground during the glue injection work.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The utility model slides a hollow column in the base so that the circular ring at the lower end of the hollow column and the limit cover contact the ground, and then pours sealant into the cylinder. The delivery pump can be started to deliver sealant to the limit cover through the feed pipe and the discharge pipe. After the sealant contacts the ground, it is located between the limit cover and the circular ring. After the sealant solidifies, the limit cover will be in sealing contact with the ground, thereby improving the airtightness of subsequent inspection work. The outer diameter of the water cylinder is consistent with the inner diameter of the hollow column. During inspection, the water cylinder is filled with water through the water inlet pipe, the valve on the water cylinder is opened, and the valve on the water inlet pipe is closed. At this time, water will fall between the circular ring and the ground. After waiting for the water level in the water cylinder to stabilize, the reading of the scale bar is recorded. After a period of time, the reading of the scale bar on the surface of the water cylinder is recorded again. In this way, it is possible to observe whether the area is water seeping. The setting of the sealant can improve the accuracy of the building ground waterproofing work.

[0020] 2. The utility model can drive the rotating shaft and the scraper thereon to rotate by starting the driving motor, so as to facilitate the discharge of the sealant in the cylinder. By closing the valve on the water inlet pipe, opening the valve on the water cylinder, and starting the vacuum pump, the water cylinder can be vacuumed, thereby achieving the effect of increasing the negative pressure in the water cylinder. If there are gaps in the ground that can seep water, the speed of water seepage can be accelerated, saving the waiting time of the staff. By starting the cylinder, the slider and the hollow column thereon can be driven to move downward to contact the ground, thereby improving the stability of the contact between the limit cover and the ground during the glue injection work.
