Description

Technical Field

[0001] The invention relates to the field of sealing of assembled water tanks, and in particular to a water-stopping device and method for an underground assembled water tank. Background Art

[0002] As a key water conservancy project facility, water reservoirs play a vital role in ensuring water supply, promoting agricultural development and improving the ecological environment. Traditionally, reinforced concrete water reservoirs are widely used because of their durability, but the construction process of such water reservoirs is complicated and costly, and they also face challenges such as insufficient crack resistance and easy leakage. In contrast, the emerging prefabricated water reservoirs have become a more advanced and efficient water storage solution with their advantages such as convenient construction, low cost, high adaptability and excellent safety.

[0003] However, due to the existence of joints between sub-modules, how to ensure the water-stopping effect of these gaps becomes a key issue. The traditional embedded water-stopping structure is generally only a simple single-layer water-stopping strip for waterproofing. In actual use, when facing the strong water pressure and water flow inside the reservoir, its long-term anti-leakage performance is often difficult to guarantee. In addition, if there is a leak in the water-stopping strip, the staff will not be able to know it in the first time, which may easily cause a certain degree of hidden danger. Therefore, it is necessary to consider how to solve this problem. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art, and to propose an underground assembled water-stopping device for a water-reservoir. During actual use, the water-stopping device utilizes three layers of waterproofing to greatly improve the sealing effect.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] The buried assembled water-stopping device for a water storage tank comprises two template bodies, a water-stopping strip is arranged between opposite sides of the two template bodies, rectangular grooves are arranged through the two template bodies, through grooves are arranged on opposite side walls of the two rectangular grooves, a blocking groove is arranged on the rear sides of the two template bodies, and a rectangular strip is arranged through the two rectangular grooves and the two through grooves; a first sealing mechanism, the first sealing mechanism comprises two rectangular sealing airbags symmetrically fixedly connected to the rear sides of the rectangular strips, a pressure regulating module cooperating with the rectangular sealing airbags is installed on the rear side of the rectangular strips, and the pressure regulating module is used to adjust the actual sealing effect; a second sealing mechanism, the second sealing mechanism is located on both sides of the rectangular strips to improve the actual sealing effect; a reminding mechanism, the reminding mechanism is used to remind when leakage occurs in both the first sealing mechanism and the second sealing mechanism, so as to facilitate the staff to handle it in time.

[0007] Preferably, anti-deflection strips are provided on both sides of the two rectangular sealed airbags, and the front side of each anti-deflection strip is fixedly connected to the rear side wall of the rectangular strip.

[0008] Preferably, the pressure regulating module includes a connecting strip fixedly connected to the rear side of the rectangular strip, a piston groove is provided on the rear side of the connecting strip, a rectangular piston strip that can slide back and forth is arranged in the piston groove, and the front side of the rectangular piston strip is elastically connected to the front inner wall of the piston groove by a spring.

[0009] Preferably, the front space of the piston groove is connected with a main pipeline, the other end of the main pipeline is connected with two branch pipelines, and the other ends of the two branch pipelines are respectively connected with two rectangular sealing airbags.

[0010] Preferably, the second sealing mechanism includes slide grooves opened on both sides of the rectangular bar, and sealing slide strips that can slide left and right are arranged in the two slide grooves. A transmission cavity is opened inside the rectangular bar, and the inner top of the transmission cavity is rotatably connected with the first rotating shaft, and the second rotating shaft is rotatably connected between the left and right inner walls of the transmission cavity. Thread grooves are opened on the opposite sides of the two sealing slide strips, and thread layers are arranged at both ends of the second rotating shaft and extend into the two thread grooves respectively. Both ends of the second rotating shaft are threadedly connected to the corresponding thread layers, and the thread directions of the two thread layers on the second rotating shaft are opposite. The lower end of the first rotating shaft is fixedly connected with the first bevel gear, and the second rotating shaft is fixedly connected with the second bevel gear, the first bevel gear is meshed with the second bevel gear, and the upper end of the first rotating shaft extends to the outside and is fixedly connected with a connecting round block, and the connecting round block is provided with a cross groove.

[0011] Preferably, the upper ends of the two sealing slides are fixedly connected with L-shaped connecting plates, and the horizontal parts of the two L-shaped connecting plates are connected to the template body through a plurality of connecting screws.

[0012] Preferably, the reminder mechanism includes a controller fixedly connected to the upper end of the rectangular bar, an alarm is installed on the upper end of the controller, and two water level switches are symmetrically installed on the front side of the rectangular bar, and the two water level switches are used to control the alarm.

[0013] The present invention also discloses a method for stopping water in an underground assembled water storage tank, which uses the above-mentioned water stopping device and comprises the following steps:

[0014] Step 1: After the two formwork bodies are connected, glue the water stop strip to the rear part of the connection;

[0015] Step 2: Insert the rectangular strip into the two rectangular slots and the two through slots;

[0016] Step 3: After the insertion is completed, use a cross screwdriver to screw the connecting screws to drive the first shaft to rotate, and cooperate with the first bevel gear and the second bevel gear to rotate the second shaft. The rotation of the second shaft will rotate the two threaded layers, and then the two sealing slides will move in opposite directions and fit completely with the opposite inner walls of the two rectangular grooves;

[0017] Step 4: Use multiple connecting screws to connect the L-shaped connecting plate to the template body.

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

[0019] 1. The present invention significantly reduces the friction during the installation process by designing the sliding connection between the rectangular strip and the through groove and the rectangular groove, as well as the non-completely expanded state of the rectangular sealing airbag in the initial state, making the insertion operation simpler and faster, effectively shortening the construction time and improving the installation efficiency.

[0020] 2. The first and second rotating shafts are driven to rotate by connecting screws, which in turn drives the threaded layer to rotate, so that the sealing slide extends to both sides, closely fits the inner wall of the rectangular groove, and forms a triple sealing system with the rectangular sealing airbag and the water stop strip. This design greatly enhances the sealing performance of the water stop device, effectively reduces the risk of water leakage, and ensures the quality and safety of the project.

[0021] 3. As the amount of water inside the reservoir increases, the rectangular piston bar in the present invention moves forward under the action of the water pressure, automatically pressing the gas in the piston groove into the rectangular sealing airbag, causing it to further expand and fit more closely with the rectangular groove, thereby achieving adaptive enhancement of the sealing effect and improving the reliability and durability of the device.

[0022] 4. The present invention is also equipped with a water level switch and an alarm system. Once a leak occurs, water accumulates in a specific area to trigger the water level switch. The alarm is made to sound intermittently through the controller, promptly reminding the staff to deal with it, ensuring that the problem can be quickly discovered and resolved, effectively avoiding potential safety hazards and losses.

[0035] As an embodiment of the present invention, it also includes a second sealing mechanism, which is located on both sides of the rectangular strip 6 to improve the actual sealing effect. The second sealing mechanism includes a slide groove 16 opened on both sides of the rectangular strip 6, and a sealing slide 17 that can slide left and right is arranged in the two slide grooves 16. A transmission cavity 18 is opened inside the rectangular strip 6, and the inner top of the transmission cavity 18 is rotatably connected with a first rotating shaft 19, and the left and right inner walls of the transmission cavity 18 are rotatably connected with a second rotating shaft 20. The opposite sides of the two sealing slides 17 are opened with a thread groove 11, and both ends of the second rotating shaft 20 are provided with a thread layer 23, which extends into the two thread grooves 11 respectively.

[0040] After the connection is completed, the triple sealing effect of the rectangular sealing airbag 13, the sealing slide 17 and the water stop strip 5 makes the water stop device have an excellent sealing and water stop effect, reducing the risk of water leakage;

[0041] It should be noted that if the amount of water inside the water reservoir increases, the pressure of the water on the rectangular piston strip 27 will increase, thereby pushing the rectangular piston strip 27 forward and pressing the gas in the piston groove 25 into the two rectangular sealing airbags 13, so that the two rectangular sealing airbags 13 further expand and fit more closely with the rectangular groove 2, so that the actual sealing effect is further improved;
