Description

Technical Field

[0001] This utility model relates to the field of concrete testing, specifically a concrete testing tank for preventing concrete cracking. Background Technology

[0002] Concrete is one of the most important civil engineering materials in modern times. It is an artificial stone made of cement, mortar, water and other admixtures. When concrete is used, its quality needs to be tested. Therefore, concrete test tanks are needed to hold the concrete and test its quality.

[0003] According to the published patent 202322032035.0, "A Concrete Testing Tank for Preventing Concrete Cracking," it includes a tank, a placement platform, a pressurizing cylinder, a fixing frame, a water storage tank, a water storage pipe, a baffle plate, and a discharge baffle plate. The placement platform is located on one side of the outer wall of the tank, and the pressurizing cylinder is located in the center of the surface of the placement platform. The fixing frame is located above the tank, and the water storage tank is located in the center of the surface of the fixing frame. The water storage pipe is located below the water storage tank and below the center of the fixing frame. A baffle plate is located on one edge of the top of the tank, above the placement platform. The other end of the tank is open, and a discharge baffle plate is located at the opening of the other end of the tank. This invention features a liftable bottom surface within the tank, allowing for easy removal of the concrete after it has solidified. Furthermore, a water circulation structure is incorporated into the tank wall to accelerate the concrete's solidification process.

[0004] However, during concrete testing, humidification is typically required to prevent cracking. In traditional testing tanks, the nozzle is usually installed above the concrete, ensuring that water primarily wets the upper surface. However, since the concrete bottom rests directly on the bottom of the testing tank, water sprayed from above cannot reach the bottom, leading to insufficient moisture supply and potential cracking. This cracking not only affects test accuracy but can also mislead performance evaluations. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies, adapt to practical needs, and provide a concrete testing tank to prevent concrete cracking. This addresses the current practice of humidifying concrete during testing to prevent cracking. In traditional testing tanks, the nozzle is typically installed above the concrete, allowing water to primarily wet the upper surface. However, since the bottom of the concrete is placed directly on the bottom of the testing tank, the water sprayed from above cannot directly reach the bottom, leading to insufficient moisture supply and potential cracking. This cracking not only affects the accuracy of the test but also misleads the evaluation of concrete performance.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: A concrete test tank for preventing concrete cracking is designed, comprising a test tank body, an opening at the front end of the test tank body, a front cover plate installed at the opening, a control host installed on the side of the test tank body, an L-shaped plate fixed to the rear end of the top of the test tank body, a motor installed at the top rear end of the L-shaped plate, a threaded rod connected to the front end of the motor through the L-shaped plate, a limit block fixed to the front end of the threaded rod through a moving block, and the threaded rod being threadedly connected to a threaded hole in the moving block, a limit rod penetrating the top end of the moving block, one end of the limit rod being fixed to the L-shaped plate, a first spraying assembly provided at the bottom of the moving block, a second spraying assembly installed at the bottom of the test tank body, a partition net provided between the first and second spraying assemblies, and the partition net being installed inside the test tank body.

[0007] Preferably, the first spraying assembly includes a water tank, a first water-air dual-purpose pump, a first water pipe, a first connecting pipe, and a first nozzle.

[0008] Preferably, the water tank is installed at the bottom of the movable block, and the bottom of the water tank is connected to a first water-air dual-purpose pump. The bottom of the first water-air dual-purpose pump is connected to a first water pipe, and the bottom of the first water pipe is connected to a first connecting pipe. Both ends of the first connecting pipe are sealed structures, and the bottom of the first connecting pipe is connected to multiple second nozzles.

[0009] Preferably, the second spraying assembly includes a support rod, a second water-air dual-purpose pump, a second water pipe, a third water pipe, a second connecting pipe, and a second nozzle.

[0010] Preferably, the support rod is installed inside the rear end of the test tank, and a second water-air dual-purpose pump is fixed at the front end of the support rod. The upper and lower ends of the second water-air dual-purpose pump are respectively connected to a second water pipe and a third water pipe.

[0011] Preferably, the top of the second water pipe is connected to a second connecting pipe, the two ends of the second connecting pipe are sealed, and the top of the second connecting pipe is connected to multiple second nozzles.

[0012] Preferably, semiconductor cooling chips are installed on both the front and rear ends of the water tank, and the cold end of the semiconductor cooling chip is in contact with the outer wall of the water tank.

[0013] Preferably, the upper and lower ends of the side of the water tank and the side of the test tank are all connected to one end of a pipe, and the other end of the pipe is detachably connected to a pipe cover.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model combines a first spraying component and a second spraying component. The first spraying component, driven by a threaded rod, can move flexibly above the concrete, ensuring uniform humidification of all areas on the top of the concrete and effectively preventing cracking. Furthermore, due to the presence of a mesh screen, the sprayed water can penetrate the screen and flow into the bottom of the test tank. At this point, the second spraying component comes into play, drawing up the water accumulated at the bottom of the tank and spraying it directly onto the bottom of the concrete. This not only utilizes the water resources sprayed above but also achieves direct humidification of the bottom of the concrete, improving the overall humidification effect and anti-cracking performance. It solves the problem that currently, in concrete testing, humidification is usually required to prevent cracking. In traditional test chambers, the nozzles are typically mounted above the concrete, allowing water to primarily wet the upper surface. However, since the concrete bottom is placed directly on the bottom of the test chamber, the water sprayed from above cannot reach the bottom of the concrete directly, resulting in insufficient moisture supply and a tendency for cracking. Cracks at the bottom of the concrete not only affect the accuracy of the test but also create misleading technical problems in the evaluation of concrete performance.

[0016] 2. This utility model combines a semiconductor cooling chip and a first water-air dual-purpose pump. During concrete testing, the semiconductor cooling chip lowers the temperature of the water in the tank, allowing the first water-air dual-purpose pump to spray cooler water, thus effectively cooling the concrete. This cooling not only slows down the evaporation rate of moisture inside the concrete, maintaining its internal humidity and improving its resistance to cracking, but also allows the first water-air dual-purpose pump to continue operating after all the water in the tank has been sprayed out, spraying cool air to further enhance the cooling effect.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0022] Example 1: A concrete test tank for preventing concrete cracking, see [link to example]. Figures 1 to 3The test tank includes a test tank 1 with an opening at its front end. A front cover plate 104 is installed at the opening. A control host 101 is installed on the side of the test tank 1. An L-shaped plate 2 is fixed to the top and rear end of the test tank 1. A motor 201 is installed at the top rear end of the L-shaped plate 2. The front end of the motor 201 passes through the L-shaped plate 2 and is connected to a threaded rod 210. The front end of the threaded rod 210 passes through a moving block 205 and is fixed to a limit block 211. The threaded rod 210 is threadedly connected to a threaded hole in the moving block 205. A limit rod 212 passes through the top end of the moving block 205. One end of the limit rod 212 is connected to the L-shaped plate 205. The plate 2 is fixed, and a first spraying component is installed at the bottom of the movable block 205. A second spraying component is installed at the bottom of the test tank 1. A partition net 203 is provided between the first and second spraying components. The partition net 203 is installed inside the test tank 1, and the concrete block is placed on the top surface of the partition net 203. The partition net 203 provides stable support for the concrete block. When it is necessary to humidify the top surface of the concrete block, the first water-air dual-purpose pump 206 is started. The first water-air dual-purpose pump 206 draws water from the water tank 202, and the water enters the first connecting pipe 208 through the first water pipe 207. The water flows in the first connecting pipe 208 and is finally sprayed evenly through multiple first nozzles 209 at the bottom to humidify the top surface of the concrete block. Simultaneously, the motor 201 is started, driving the threaded rod 210 to rotate. Since the threaded rod 210 is tightly fitted with the threaded hole in the moving block 205, the moving block 205 moves along the length of the tank under the drive of the threaded rod 210. The movement of the moving block 205 drives the water tank 202, the first water pipe 207, the first connecting pipe 208, and multiple first nozzles 209 to move together, achieving uniform humidification of different positions on the top surface of the concrete block. During the top humidification process, the sprayed water will penetrate the mesh 203 and flow into the bottom of the test tank 1. When a certain amount of water accumulates at the bottom of the tank, the second water-air dual-purpose pump 301 is started. The second water-air dual-purpose pump 301 draws water from the bottom of the tank through the third water pipe 305 and delivers the water to the second nozzle 304 through the second water pipe 302. The second nozzle 304 sprays water directly to humidify the bottom of the concrete block. This method not only utilizes the water resources that penetrate the mesh 203 after being sprayed from above, but also achieves direct humidification of the bottom of the concrete, improving the overall humidification effect and anti-cracking performance. It solves the problem that currently, in concrete testing, humidification is usually required to prevent cracking. In traditional test chambers, the nozzle is generally installed above the concrete, so that when spraying water, it mainly wets the upper surface of the concrete. However, since the bottom of the concrete is placed directly on the bottom of the test chamber, the water sprayed from above cannot directly reach the bottom of the concrete, resulting in insufficient water supply to the bottom and a tendency for cracking. Cracking at the bottom of the concrete not only affects the accuracy of the test but also misleads the performance evaluation of the concrete.

[0023] For details, see Figure 2 The first spraying assembly includes a water tank 202, a first water-air dual-purpose pump 206, a first water pipe 207, a first connecting pipe 208, and a first nozzle 209.

[0024] For more details, see Figure 2 The water tank 202 is installed at the bottom of the movable block 205. The bottom of the water tank 202 is connected to the first water-air dual-purpose pump 206. The bottom of the first water-air dual-purpose pump 206 is connected to the first water pipe 207. The bottom of the first water pipe 207 is connected to the first connecting pipe 208. Both ends of the first connecting pipe 208 are sealed. The bottom of the first connecting pipe 208 is connected to multiple second nozzles 304.

[0025] Further, see Figure 3 The second spraying assembly includes a support rod 3, a second water-air dual-purpose pump 301, a second water pipe 302, a third water pipe 305, a second connecting pipe 303, and a second nozzle 304.

[0026] Further, see Figure 3 The support rod 3 is installed inside the rear end of the test tank 1. The front end of the support rod 3 is fixed with a second water-air dual-purpose pump 301. The upper and lower ends of the second water-air dual-purpose pump 301 are respectively connected to a second water pipe 302 and a third water pipe 305.

[0027] It is worth noting that, see Figure 3 The top of the second water pipe 302 is connected to a second connecting pipe 303. The two ends of the second connecting pipe 303 are sealed. The top of the second connecting pipe 303 is connected to multiple second nozzles 304.

[0028] It is worth noting that, see Figure 1Semiconductor cooling chips 204 are installed on both the front and rear ends of the water tank 202. Since the cold end of the semiconductor cooling chip 204 is in contact with the outer wall of the water tank 202, and the semiconductor cooling chip 204 is installed close to the bottom or side of the water tank 202, when the semiconductor cooling chip 204 is energized, its cold surface begins to absorb heat from the water in the water tank 202, causing the water temperature to gradually decrease. Simultaneously, the hot end generates heat, which, since it is directly exposed to the outside, is directly dissipated into the air to maintain the normal operating temperature of the semiconductor cooling chip 204. Once the water in the water tank 202 has been cooled to the set temperature by the semiconductor cooling chip 204, the first water-air dual-purpose pump 206 starts working, pumping water from the water tank 202... The water is drawn from tank 202 and transported to the nozzles through water pipes. The nozzles spray water onto the surface of the concrete block in the form of a mist or a fine stream, effectively cooling it. After the cooling water is sprayed onto the concrete block, its lower temperature slows down the evaporation rate of the moisture inside the concrete, helping to maintain the internal humidity of the concrete and thus improving its resistance to cracking. After the water in tank 202 has been completely sprayed, if further enhancement of the cooling effect is needed, the first water-air dual-purpose pump 206 can continue to work. At this time, the first water-air dual-purpose pump 206 will draw the remaining water or air from tank 202 and spray cold air through the nozzles. The cold air can further reduce the temperature of the concrete block and enhance the cooling effect.

[0029] It is worth mentioning that, see Figure 1 The upper and lower ends of the water tank 202 and the side of the test tank 1 are all connected to one end of the pipe 102, and the other end of the pipe 102 is detachably connected to the pipe cover 103.

[0030] When using a concrete test chamber designed to prevent concrete cracking, a concrete block is placed on the top surface of a mesh 203, which provides stable support for the concrete block. When humidification of the top surface of the concrete block is required, a first water-air pump 206 is activated. The first water-air pump 206 draws water from a water tank 202, and the water enters a first connecting pipe 208 through a first water pipe 207. The water flows in the first connecting pipe 208 and is eventually sprayed evenly through multiple first nozzles 209 at the bottom to humidify the top surface of the concrete block. Simultaneously, the motor 201 is started, driving the threaded rod 210 to rotate. Since the threaded rod 210 is tightly fitted with the threaded hole in the moving block 205, the moving block 205 moves along the length of the tank under the drive of the threaded rod 210. The movement of the moving block 205 drives the water tank 202, the first water pipe 207, the first connecting pipe 208, and multiple first nozzles 209 to move together, achieving uniform humidification of different positions on the top surface of the concrete block. During the top humidification process, the sprayed water will penetrate the mesh 203 and flow into the bottom of the test tank 1. When a certain amount of water accumulates at the bottom of the tank, the second water-air dual-purpose pump 301 is started. The second water-air dual-purpose pump 301 draws water from the bottom of the tank through the third water pipe 305 and delivers the water to the second nozzle 304 through the second water pipe 302. The second nozzle 304 sprays water directly to humidify the bottom of the concrete block. Not only does it utilize the water resources that penetrate the mesh 203 after being sprayed from above, it also achieves direct humidification of the bottom of the concrete, improving the overall humidification effect and anti-cracking performance. When the semiconductor cooling chip 204 is powered on, its cold side begins to absorb heat from the water in the water tank 202, causing the water temperature to gradually decrease. At the same time, the hot end generates heat, which is directly dissipated into the air since the hot end is directly exposed to the outside, thus maintaining the normal operating temperature of the semiconductor cooling chip 204. When the water in the water tank 202 is cooled to the set temperature by the semiconductor cooling chip 204, the first water-air dual-purpose pump 206 starts to work, drawing water from the water tank 202 and transporting it through water pipes. The water is delivered to the nozzle, which sprays water onto the surface of the concrete block in the form of a mist or a fine stream, effectively cooling it. After the cooling water is sprayed onto the concrete block, its lower temperature slows down the evaporation rate of moisture inside the concrete, helping to maintain the internal humidity of the concrete and thus improving its resistance to cracking. After the water in the water tank 202 has been completely sprayed, if further enhancement of the cooling effect is needed, the first water-air dual-purpose pump 206 can continue to work. At this time, the first water-air dual-purpose pump 206 will draw the remaining water or air in the water tank 202 and spray cold air through the nozzle. The cold air can further reduce the temperature of the concrete block and enhance the cooling effect.
