Description

Technical Field

[0001] This utility model belongs to the field of civil engineering construction, and specifically relates to a concrete test block curing device. Background Technology

[0002] Concrete test block curing is essential to ensure that the concrete test blocks reach their design strength during the curing period. After pouring, concrete test blocks require a certain curing time to guarantee the curing effect. The main curing methods include: Water curing: Keeping the surface of the concrete test block moist, such as by covering it with damp felt or fabric and watering it appropriately. Insulation covering: Using insulation covering can effectively maintain the temperature of the concrete test block and improve its strength. Using a curing chamber: A closed curing chamber can be used to cure the concrete test blocks, maintaining the appropriate temperature and humidity.

[0003] Among these methods, using a curing chamber to cure concrete test blocks allows for better control of the curing environment, including factors such as temperature, humidity, and ventilation, ensuring the test blocks remain in a relatively stable state during curing. Ensuring the test blocks reach their design strength plays a crucial role in the construction quality and safety of concrete structures.

[0004] To achieve a high degree of automation, existing concrete curing chambers require numerous sensors, such as humidity sensors and specimen positioning sensors. They also necessitate the use of chips to analyze sensor data and control equipment like water pumps, resulting in high costs. Furthermore, existing curing chambers drain excess water during curing, and heat dissipates with the water, leading to high energy consumption. Utility Model Content

[0005] In order to overcome the problems mentioned in the background art, this utility model provides a concrete test block curing device.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0007] A concrete test block curing device includes a curing container body, which comprises a curing chamber, a water collection chamber, and an equipment chamber. The curing chamber is located above the water collection chamber and is separated from the water collection chamber by a transverse partition. The transverse partition has a vent hole and a vertically arranged guide seat. The vent hole connects the curing chamber and the water collection chamber. An installation plate is disposed in the curing chamber. A guide rod and an elastic rod are installed at the lower end of the installation plate. The guide rod passes through the guide seat and slides with it. The elastic rod passes vertically through the transverse partition and provides vertical elasticity to the installation plate, allowing it to move vertically relative to the transverse partition. When no concrete test block is placed on the installation plate, the elastic rod is extended, and the installation plate is in a high position. When a concrete test block is placed on the installation plate, the elastic rod is compressed, and the installation plate is in a low position. The device is equipped with a first switch contact and a conductive ring on the guide rod. When the mounting plate is in the high position, the first switch contact is offset from the conductive ring, and the first switch contact is open. When the mounting plate is in the low position, the first switch contact is aligned with the conductive ring, and the first switch contact is closed. The equipment cavity is isolated from the curing cavity and the water accumulation cavity. The equipment cavity is equipped with a water pump and a battery. The water inlet of the water pump is connected to an external water source, and the water outlet of the water pump is connected to the water accumulation cavity. The first switch contact is installed on the connection circuit of the water pump and the battery. When the first switch contact is connected, the water pump is energized and pumps water into the water accumulation cavity. The equipment cavity is also equipped with a spray device and a heat preservation device. The spray device is used to turn the water in the water accumulation cavity into water mist and spray it into the curing cavity. The heat preservation device is used to heat the curing cavity to keep the curing cavity at a constant temperature.

[0008] Furthermore, the spraying device includes a spraying water pump and a spraying head. The inlet of the spraying water pump is connected to the water collection chamber, and the outlet of the spraying water pump extends to the upper part of the curing chamber and is connected to the spraying head installed on the top of the curing chamber. The spraying head can atomize the water and spray it downwards. The spraying water pump is connected to a battery.

[0009] Furthermore, the heat preservation device includes a temperature controller, a thermocouple, and a heating resistor. The temperature controller is connected to the thermocouple and the heating resistor respectively. The thermocouple is inserted into the water accumulation cavity to detect the temperature of the water in the water accumulation cavity. The heating resistor is used to heat the water in the water accumulation cavity. The heating resistor is electrically connected to the battery. The temperature controller is used to control the power of the heating resistor and the on / off state of the heating resistor and the battery.

[0010] Furthermore, a first float switch is installed inside the water accumulation chamber. The first float switch includes a first float cavity, a first float, a first float rod, a first switch partition, a first float contact, and a first float conductive block. A water inlet is opened at the bottom of the first float cavity. The first switch partition divides the internal space of the first float cavity into upper and lower parts. The first float is located in the lower half of the first float cavity. The lower end of the first float rod is connected to the first float, and the upper end passes through the first switch partition and connects to the first float conductive block. The first float contact is located on the upper surface of the first switch partition. The first float contact contacts the first float conductive block, so that the first float contact is in the connected state. The first float contact is installed on the connection circuit between the water pump and the battery. When the first float rises under the action of buoyancy, it drives the first float conductive block to move upward, and the first float contact separates from the first float conductive block, so that the first float contact is in the disconnected state.

[0011] Furthermore, a counterweight is fixedly installed on the first float conductive block.

[0012] Furthermore, a second float switch is installed inside the water accumulation chamber. The second float switch includes a second float cavity, a second float, a second float rod, a second float contact, and a second float conductive block. A water inlet is opened at the bottom of the second float cavity. The second float is located in the lower part of the second float cavity. The lower end of the second float rod is connected to the second float, and the upper end is connected to the second float conductive block. The second float contact is located on the upper surface of the second float cavity. The second float contact is separated from the second float conductive block and is in an open state. The second float contact is installed on the connection circuit between the spray pump and the battery. When the second float rises under the action of buoyancy, it drives the second float conductive block to move upward, and the second float contact contacts the second float conductive block, so that the second float contact is in an on state. The height of the second float switch inside the water accumulation chamber is lower than the height of the first float switch.

[0013] Furthermore, the elastic rod includes a rod, a limiting end, and a spring. The rod passes through the transverse partition, with its upper end connected to the mounting plate, the limiting end installed at the lower end of the rod, and the spring sleeved on the rod with its upper end connected to the mounting plate and its lower end connected to the upper surface of the transverse partition.

[0014] Furthermore, the equipment chamber is installed on the side or back of the curing chamber and the water accumulation chamber, and a door is opened on the front of both the equipment chamber and the curing chamber.

[0015] Furthermore, a normally closed drain outlet is provided at the bottom of the water accumulation chamber.

[0016] Furthermore, the battery is a lithium battery.

[0017] The beneficial effects of this utility model are:

[0018] This invention features a conductive ring on the guide rod of the mounting plate and a first switch contact in the guide seat of the transverse partition, forming an inductive switch that can sense whether a concrete specimen is placed on the mounting plate. Simultaneously, this invention also includes a first float switch and a second float switch, which work together to regulate the operation of the inlet pump and the spray pump. This achieves automated pump control without relying on chip control or software code, significantly reducing the cost of the concrete specimen curing device and realizing low-cost, highly automated concrete specimen curing.

[0019] This invention involves filling the water collection chamber with water when placing concrete test blocks into the curing device, and then spraying the water from the chamber. The sprayed water mist not only moistens the concrete test specimen but also causes airflow. The sprayed water mist then falls back into the water collection chamber, thus achieving water recycling. During the curing of the concrete test blocks, the curing device neither discharges water nor air, effectively maintaining the temperature and humidity of the curing chamber while significantly reducing energy consumption.

[0033] This utility model provides, for example Figure 1-2 As shown, this utility model provides a concrete test block curing device. The main structure includes a curing container body 1, which includes a curing chamber 11, a water collection chamber 12, and an equipment chamber 13. A spray head 52 and an installation plate 2 are installed in the curing chamber 11. A first float switch 7, a second float switch 8, and a heating resistor 62 are installed in the water collection chamber 12. A water pump 3, a battery 4, a spray water pump 51, a temperature controller 61, and other equipment are installed in the equipment chamber 13.

[0034] A transverse partition 14 is provided between the curing chamber 11 and the water accumulation chamber 12. The transverse partition 14 is a disc structure with ventilation holes 15 distributed around its perimeter. A large through hole is provided in the middle of the transverse partition 14 for the rod 22a of the elastic rod 22 to pass through. The diameter of the large through hole is smaller than that of the limiting end 22b. Therefore, when the concrete test block 9 is not placed on the mounting plate 2, the spring 22c pushes the mounting plate 2 upward, and the limiting end 22b is attached to the lower surface of the transverse partition 14, restricting the mounting plate 2 from moving further upward. When the concrete test block 9 is placed on the mounting plate 2, the spring 22c is compressed, and the mounting plate 2 approaches contact with the upper surface of the transverse partition 14.

[0035] Four guide seats 16 are evenly curved on the lower surface of the transverse partition 14. Each guide seat 16 is a ring structure with through holes at the top and bottom. The guide rod 21 of the mounting plate 2 passes through the guide seat 16. The cooperation between the guide rod 21 and the guide seat 16 prevents the mounting plate 2 from rotating or shaking. A first switch contact 17 is provided in the guide seat 16, and a conductive ring 21a is provided on the guide rod 21. When the concrete test block 9 is not placed on the mounting plate 2, the conductive ring 21a is located above the first switch contact 17, and the two do not contact each other. Figure 3 As shown, when the concrete test block 9 is placed on the mounting plate 2, the conductive ring 21a moves down and contacts the first switch contact 17, as... Figure 8 As shown.

[0036] like Figure 6 As shown, the first switch contact 17 and the first float contact 75 are both connected in series in the circuit between the spray pump 51 and the battery 4, and the second float contact 85 is connected in series in the connection circuit between the spray pump 51 and the battery 4. The first float contact 75 is installed in the first float switch 7, and the second float contact 85 is installed in the second float switch 8.

[0037] like Figure 4 As shown, the first float switch 7 includes a first float cavity 71, a first float 72, a first float rod 73, a first switch partition 74, a first float contact 75, and a first float conductive block 76. The first float cavity 71 has a water inlet hole at its bottom. The first switch partition 74 divides the internal space of the first float cavity 71 into upper and lower parts. The first float 72 is located in the lower half of the first float cavity 71. The lower end of the first float rod 73 is connected to the first float 72, and the upper end passes through the first switch partition 74 and connects to the first float contact 75. The float conductive block 76 and the first float contact 75 are located on the upper surface of the first switch isolation 74. The first float contact 75 contacts the first float conductive block 76, so that the first float contact 75 is in the connected state. The first float contact 75 is installed on the connection circuit between the water pump 3 and the battery 4. When the first float 72 floats up under the action of buoyancy, it drives the first float conductive block 76 to move up, and the first float contact 75 separates from the first float conductive block 76, so that the first float contact 75 is in the disconnected state.

[0038] like Figure 5As shown, the second float switch 8 includes a second float cavity 81, a second float 82, a second float rod 83, a second float contact 85, and a second float conductive block 84. The bottom of the second float cavity 81 has a water inlet hole. The second float 82 is located in the lower part of the second float cavity 81. The lower end of the second float rod 83 is connected to the second float 82, and the upper end is connected to the second float conductive block 84. The second float contact 85 is located on the upper surface of the second float cavity 81. The second float contact 85 is separated from the second float conductive block 84 and is in the open state. The second float contact 85 is installed on the connection circuit between the spray pump 51 and the battery 4. When the second float 82 floats up under the action of buoyancy, it drives the second float conductive block 84 to move upward, and the second float contact 85 contacts the second float conductive block 84, so that the second float contact 85 is in the closed state.

[0039] from Figure 2 It can be seen that the height of the second float switch 8 in the water accumulation chamber 12 is lower than the height of the first float switch 7. However, the height difference between the two is limited, that is, when the first float contact 75 is open, the water in the water accumulation chamber 12 cannot reach the second float contact 85.

[0040] The following explains the usage process of the concrete test block curing device of this utility model:

[0041] Open the door of equipment chamber 13, place the concrete test block 9 to be cured on the mounting plate 2, close the door of equipment chamber 13, the weight of the concrete test block 9 will press the mounting plate 2 downward, causing the guide rod 21 to move down in the guide seat 16, thereby causing the conductive ring 21a to contact the first switch contact 17. Figure 8 As shown. At this time, both the first switch contact 17 and the first switch disconnect 74 are in the ON state, the water pump 3 is energized, and water is injected into the water accumulation chamber 12. As the water level rises, the second float switch 8 first receives water, the second float 82 rises, the second float conductive block 84 contacts the second float contact 85, and then the spray pump 51 is turned on. The spray pump 51 pumps water to the spray head 52 to spray water mist to keep the concrete test block 9 moist. As the water level continues to rise, the first float switch 7 receives water, the first float 72 rises, the first float conductive block 76 separates from the first float contact 75, the water pump 3 is de-energized, and the water pump 3 stops injecting water into the water accumulation chamber 12. During this process, the thermocouple detects the water temperature, and the temperature controller 61 controls the heating resistor 62 to heat according to the water temperature, so that the water temperature is maintained within a certain range.

[0042] This state will be maintained throughout the entire concrete test block curing cycle. When the concrete test block 9 has been cured for the predetermined time, the door is opened and the concrete test block 9 is taken out. The mounting plate 2 moves upward under the action of the spring 22c and returns to the initial state. The drain outlet 12a is opened to drain the water in the water accumulation chamber 12, thus completing the entire concrete test block curing process.

[0043] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
