Description

Technical Field

[0001] This utility model relates to the field of building engineering, and in particular to a standard constant temperature and humidity concrete curing box. Background Technology

[0002] Traditional curing methods are significantly affected by the environment and climate. Seasonal changes and regional differences can lead to large fluctuations in temperature and humidity, making it difficult to maintain consistent curing conditions for concrete samples. This directly results in large deviations in test data for concrete with the same mix proportion at different times or locations, making it unreliable as a basis for judging project quality. Even with simple manual control methods, there are still obvious shortcomings. Soaking in a water tank can ensure humidity, but it is difficult to stabilize the temperature. While a humidifier in an ordinary room can increase humidity, it lacks precise control, and the humidity is prone to large fluctuations. Moreover, the temperature is affected by the room temperature and cannot meet the standard requirements. Therefore, a standard constant temperature and humidity concrete curing chamber has emerged. The standard constant temperature and humidity concrete curing chamber monitors the temperature and humidity inside the chamber in real time through sensors and transmits the data to the control module. In terms of temperature control, when the temperature is lower than the set value, the electric heating device is activated to raise the temperature, and when the temperature is higher than the set value, the compressor works to cool down and maintain a stable temperature. In terms of humidity control, when the humidity is insufficient, the humidifier runs to increase the humidity, and when the humidity is too high, it is adjusted through the ventilation or drainage system to ensure that the humidity meets the standard. The entire process is automatically controlled by a microcomputer, reducing manual intervention and ensuring that the environment inside the chamber meets the standard curing requirements for concrete. Currently, standard constant temperature and humidity concrete curing chambers play a significant role in the industry and in the constant temperature curing of concrete. However, the problem of water shortage in the humidifier has a considerable impact. Once the water in the humidifier is exhausted, the humidity inside the chamber will deviate from the standard curing requirements, directly interfering with the hydration reaction of the concrete samples. More seriously, if the water shortage is not detected in time, it will cause the humidifier to burn out, which will not only cause the humidifier to be damaged on the spot, but also affect other components inside the curing chamber due to local high temperature, thereby shortening the service life of the entire equipment, increasing maintenance costs and equipment replacement frequency, and adversely affecting the continuity and accuracy of concrete testing. Therefore, a standard constant temperature and humidity concrete curing chamber is proposed to solve the above problems. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a standard constant temperature and humidity concrete curing box, which aims to improve the problem of water shortage in the humidifiers of some standard constant temperature and humidity concrete curing boxes in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A standard constant temperature and humidity concrete curing box includes a shell, a humidifier water tank is fixedly connected to the inner wall of the shell, a rotating plate one is rotatably connected to one side of the shell, a rotating plate two is rotatably connected to one side of the shell, a metering water supply mechanism is fixedly connected to one side of the shell, and a separation mechanism is fixedly connected to both sides of the shell. The quantitative water supply mechanism includes a barrel body, one side of which is fixedly connected to one side of the shell. A cylinder is fixedly connected to the inner wall of the barrel body, and a push plate is fixedly connected to the drive end of the cylinder. A transition pipe is fixedly connected to one side of the barrel body, and connecting pipes are fixedly connected to both sides of the transition pipe. A water supply pipe is fixedly connected to the side of each of the two connecting pipes away from the transition pipe. A transmission pipe is fixedly connected to the other side of one of the water supply pipes. A sealing plate is slidably connected to the inner wall of each of the two connecting pipes, and a support assembly is fixedly connected to the side of each of the two sealing plates that is far apart from each other. The above technical solution includes: a humidifier water tank on the shell, and two rotatable plates on both sides of the shell to protect the internal structure. It also includes a metering water supply mechanism and a separation mechanism. The barrel of the metering water supply mechanism is responsible for water storage and regulation. Its internal cylinder can drive the push plate to move flexibly to control the water volume. The transition pipe on one side of the barrel is the water flow transfer hub, and the connecting pipes on both sides are responsible for diverting the flow. The water supply pipe delivers water to different places. One of the water supply pipes is connected to a transmission pipe that can guide the water to a specific location. The sealing plate inside the connecting pipe can accurately control the water flow. The support component on the outside of the sealing plate provides stable support, ensuring that it can maintain a good sealing effect under the impact of water flow and ensuring the accuracy of metering water supply.

[0005] As a further description of the above technical solution: The separation mechanism includes a base, one side of which is fixedly connected to one side of the housing, a fixed column is fixedly connected to one side of the base, a sliding column is slidably connected to the inner wall of the fixed column, a pull plate is fixedly connected to the top of the sliding column, a protruding plate is fixedly connected to the outer wall of the sliding column, a spring is sleeved on the outer wall of the sliding column, and a fixed plate is fixedly connected to one side of both the first rotating plate and the second rotating plate. Through the above technical solution: the base of the separation mechanism serves as the basic component, providing stable support for the entire mechanism; the fixed column plays a positioning and guiding role; the sliding column inside can slide flexibly; the movement of the sliding column can be easily controlled by the pull plate at the top; the convex plate on the outer wall of the sliding column cooperates with the spring, and the elastic potential energy of the spring is used to realize the reset function, ensuring that the sliding column can return to the initial position after operation; the fixed plates on rotating plate one and rotating plate two interact with the sliding column; when the sliding column moves, it can be fixed or opened by engaging or disengaging with the fixed plate, thereby achieving the purpose of controlling the opening and closing of the shell.

[0006] As a further description of the above technical solution: The support assembly includes connecting rods, one side of which is fixedly connected to one side of the sealing plate, and two connecting rods are fixedly connected to sliding plates on the side away from the sealing plate. Through the above technical solution: the connecting rod of the support component mainly plays a connecting role, which can transmit force to the sealing plate and ensure the stable operation of the sealing plate. The sliding plate cooperates with the relevant structure and provides movement guidance for the connecting rod and the sealing plate by sliding adjustment, ensuring that the sealing plate is accurately positioned when controlling the water flow and maintaining the stability of quantitative water supply.

[0007] As a further description of the above technical solution: The outer wall of the transmission pipe is fixedly connected to the inner wall of the housing, and the outer wall of the transmission pipe is fixedly connected to the inner wall of the humidifier water tank. The above technical solution involves embedding the transmission pipe inside the housing and extending it into the humidifier's water tank to form a continuous water supply path. This layout allows water to be stably delivered from the metering water supply mechanism to the water tank, avoiding leakage during the water supply process and ensuring the compactness of the water circuit, thus enabling the entire water supply system to operate efficiently.

[0008] As a further description of the above technical solution: The outer wall of the sealing plate is slidably connected to the inner wall of the connecting pipe, and the outer wall of the sliding plate is slidably connected to the inner wall of the water supply pipe. Through the above technical solution: the sealing plate slides against the inner wall of the connecting pipe, which can accurately control the flow of water and ensure accurate water volume adjustment. The sliding plate slides smoothly in the water supply pipe, providing stable guidance for the movement of the sealing plate. The two work together to make the water circuit switching flexible and tight, ensuring that the quantitative water supply process is efficient and reliable.

[0009] As a further description of the above technical solution: The outer wall of the convex plate is slidably connected to the inner wall of the fixed column, the outer wall of the sliding column is slidably connected to the inner wall of the base, the outer wall of the sliding column is slidably connected to the inner wall of the fixed plate, and the outer wall of the pull plate is in contact with the inner wall of the fixed column. The above technical solution involves the convex plate sliding inside the fixed column, the sliding column penetrating the base and embedding itself into the fixed plate, controlling the locking state of the fixed plate through sliding, and the pull plate fitting against the inner wall of the fixed column to ensure stability during operation and make the opening and closing action of the entire mechanism precise and reliable.

[0010] As a further description of the above technical solution: The top of the spring is fixedly connected to the inner wall of the fixed column, and the bottom of the spring is fixedly connected to the top of the protruding plate. The above technical solution involves connecting the two ends of the spring to the fixed structure and the moving part, respectively. By utilizing its own elastic properties, the spring stretches and stores force when the moving part is pulled. When released, the spring releases its elastic force to drive the part back to its original position, forming a stable elastic cycle. This ensures that the mechanism can automatically return to its initial state after operation and maintain reliable working performance.

[0011] As a further description of the above technical solution: The connecting pipe has a trapezoidal cross-sectional shape, the top of the fixing plate is slidably connected to the bottom of the fixing column, and the bottom of the fixing plate is slidably connected to the outer wall of the base. Through the above technical solution: the connecting pipe adopts a trapezoidal cross section, which can enhance the fit with the sealing component and improve the sealing effect. The fixing plate slides between the bottom of the fixing column and the outer wall of the base. It is both limited by the fixing column and supported by the base, ensuring that the sliding process is smooth, making the opening and closing action of the entire mechanism precise and controllable, and ensuring the stability of the connection.

[0012] This utility model has the following beneficial effects: 1. In this utility model, by activating the cylinder on the inner wall of the barrel, the push plate is driven to slide and change the internal air pressure of the barrel. With the help of the sliding plate and the connecting rod, the two sealing plates move towards or away from each other in the connecting pipe. When the sealing plates are close together, one set seals and blocks, and the other set separates, allowing external water to enter the barrel through the water supply pipe. When the sealing plates are far apart, the other set seals, and the water in the barrel enters the humidifier water tank through the water supply pipe and the transmission pipe, realizing phased water replenishment, optimizing the water shortage problem of the humidifier, and extending the service life of the maintenance box.

[0013] 2. In this utility model, pulling the pull plate drives the sliding column to move, the sliding column drives the convex plate to move, releases the base from locking the fixed plate, and allows the rotating plate to rotate. At the same time, the convex plate compresses the spring to generate elastic potential energy, and when there is no external force, the spring pushes the convex plate and the sliding column to reset.

A humidifier water tank 2 is fixedly connected to the inner wall of the shell 1, storing humidification water to provide a water source for the humidification function within the curing chamber, ensuring continuous humidification. A rotating plate 3 is rotatably connected to one side of the shell 1 for convenient maintenance of the entire working component. When closed, the rotating plate 3 forms a closed space with the shell 1. A rotating plate 4 is also rotatably connected to one side of the shell 1, allowing the rotating plate 4 to be opened or closed. It facilitates the placement and removal of concrete specimens. When closed, it forms a closed space with the shell 1 to maintain a constant temperature and humidity environment inside the chamber. A metering water supply mechanism 5 is fixedly connected to one side of the shell 1. The metering water supply mechanism 5 can periodically replenish a metered amount of water to the humidifier water tank 2 to ensure that the humidifier will not stop working due to lack of water and maintain the stable humidification function of the curing chamber. Separation mechanisms 6 are fixedly connected to both sides of the shell 1.

A metered water supply mechanism 5 on one side periodically replenishes a metered amount of water to the water tank to prevent the humidifier from running out of water and stopping. Separation mechanisms 6 on both sides control the locking and unlocking of the two rotating plates to ensure a stable environment inside the chamber. The metering water supply mechanism 5 includes a barrel 51, one side of which is fixedly connected to one side of the shell 1. The barrel 51 is used to temporarily store water and achieves water intake and drainage through changes in internal air pressure. It is an intermediate water storage component for metering water supply. A cylinder 52 is fixedly connected to the inner wall of the barrel 51. A push plate 53 is fixedly connected to the driving end of the cylinder 52. The push plate 53 slides inside the barrel 51 under the drive of the cylinder 52, changing the size of the internal space of the barrel 51, thereby changing the air pressure and providing power for water intake and drainage. A transition pipe 54 is fixedly connected to one side of the barrel 51. Connecting pipes 55 are fixedly connected to both sides of the transition pipe 54. The transition pipe 54 connects the barrel 51 and the connecting pipes 55, allowing water to flow between the barrel 51 and the connecting pipes 55. The two connecting pipes 55 are fixedly connected to water supply pipes 57 on the side away from the transition pipe 54. One of the water supply pipes 57 is fixedly connected to a transmission pipe 59 on the other side. The transmission pipe 59 introduces the water supplied by the water supply pipe 57 into the humidifier water tank 2 and is the channel for replenishing water to the humidifier water tank 2. The inner walls of the two connecting pipes 55 are slidably connected to sealing plates 56. The sealing plates 56 slide inside the connecting pipes 55 and can open or close the connecting pipes 55 to control the flow of water and realize the switching of water intake and drainage. The two sealing plates 56 are fixedly connected to support components 58 on the side away from each other. The support components 58 drive the sealing plates 56 to slide synchronously to ensure that the two sealing plates 56 move in a coordinated manner and accurately realize the opening and closing of the connecting pipes 55. Specifically, the barrel 51 is mounted on one side of the shell 1 to temporarily store water. It achieves water intake and drainage through changes in internal air pressure and is an intermediate water storage component for quantitative water supply. The cylinder 52 inside the barrel 51 drives the push plate 53 to slide, changing the internal space and air pressure to provide power for water intake and drainage. The transition pipe 54 on one side of the barrel 51 connects the connecting pipes 55 on both sides, allowing water to flow between the barrel 51 and the connecting pipe 55. The other side of the connecting pipe 55 is connected to the water supply pipe 57, one of which is connected to the transmission pipe 59, which introduces water into the humidifier water tank 2. The sealing plate 56 inside the connecting pipe 55 slides to control the water flow and realize the switching of water intake and drainage. Its outer support component 58 drives the sealing plate 56 to slide synchronously to ensure coordinated action. The separation mechanism 6 includes a base 61, one side of which is fixedly connected to one side of the housing 1. The base 61 provides mounting support for other components of the separation mechanism 6, ensuring stable operation of the separation mechanism 6. A fixed column 62 is fixedly connected to one side of the base 61. A sliding column 63 is slidably connected to the inner wall of the fixed column 62. A pull plate 64 is fixedly connected to the top of the sliding column 63. The pull plate 64 facilitates the operator to pull the sliding column 63, saving effort and making operation convenient. It is a component that controls the movement of the sliding column 63. The outer wall of the sliding column 63 is fixedly connected to the base 61. A convex plate 65 is fixedly connected to the slide column 63. The convex plate 65 moves with the slide column 63. A spring 66 is sleeved on the outer wall of the slide column 63. The spring 66 is compressed and stores elastic potential energy when the convex plate 65 moves. After the pull plate 64 is released, the elastic force pushes the convex plate 65 to drive the slide column 63 to reset, realizing automatic locking. A fixed plate 67 is fixedly connected to one side of the rotating plate 3 and the rotating plate 4. The fixed plate 67 cooperates with the slide column 63. When the slide column 63 is inserted into the fixed plate 67, it locks the rotating plate. When it is pulled out, it unlocks. It is the key component for locking the rotating plate. Specifically, the base 61 of the separation mechanism 6 is mounted on the housing 1 to provide support for other components. The fixed column 62 on one side of the base 61 contains a sliding column 63. The top pull plate 64 facilitates the movement of the sliding column 63. The protruding plate 65 on the outer wall of the sliding column 63 moves with it. The spring 66 is compressed and stores energy when the protruding plate 65 moves. After the pull plate 64 is released, the elastic force pushes the sliding column 63 to reset. The fixed plate 67 on the rotating plate 1 3 and the rotating plate 2 4 cooperate with the sliding column 63. The sliding column 63 is locked when inserted and unlocked when pulled out.

[0018] Reference Figures 2 to 4 The support assembly 58 includes connecting rods 582, one side of which is fixedly connected to one side of the sealing plate 56. Slide plates 581 are fixedly connected to the sides of both connecting rods 582 away from the sealing plate 56. The connecting rods 582 and slide plates 581 cooperate to ensure stable and secure sliding of the sealing plate 56. The outer wall of the transmission pipe 59 is fixedly connected to the inner wall of the housing 1. The housing 1 fixes the position of the transmission pipe 59, ensuring that the transmission pipe 59 can stably supply water to the humidifier water tank 2. The transmission pipe 59 is directly connected to the humidifier water tank 2 to ensure that water can smoothly enter the water tank to replenish the humidification water. The outer wall of the sealing plate 56 is slidably connected to the inner wall of the connecting pipe 55. The sealing plate 56 slides inside the connecting pipe 55 and can tightly fit the inner wall of the connecting pipe 55 to achieve a seal, or detach to allow water to pass through and control the water flow. The outer wall of the sliding plate 581 is slidably connected to the inner wall of the water supply pipe 57. The water supply pipe 57 provides a sliding guide for the sliding plate 581 to ensure that the sliding plate 581 drives the sealing plate 56 to move smoothly and accurately control the opening and closing of the connecting pipe 55. Specifically, the connecting rod 582 cooperates with the sliding plate 581 to make the sealing plate 56 slide stably and firmly. The transmission pipe 59 is fixed to the inner wall of the housing 1 and the inner wall of the humidifier water tank 2 to ensure stable water supply to the water tank for replenishment. The sealing plate 56 slides in the connecting pipe 55, sealing when in contact and allowing water to flow when out, controlling the water flow. The water supply pipe 57 provides a guide for the sliding plate 581 to ensure that it drives the sealing plate 56 to move smoothly and accurately control the opening and closing of the connecting pipe 55. The outer wall of the convex plate 65 is slidably connected to the inner wall of the fixed post 62. The fixed post 62 restricts the movement direction of the convex plate 65, ensuring that the convex plate 65 can smoothly drive the sliding post 63 to move, making the locking and unlocking actions reliable. The outer wall of the sliding post 63 is slidably connected to the inner wall of the base 61. The base 61 provides sliding support for the sliding post 63, ensuring that the sliding post 63 can accurately insert into or detach from the fixed plate 67. When the sliding post 63 is inserted into the fixed plate 67, it locks the rotating plate to the housing 1. When the sliding post 63 is pulled out, the lock is released, the rotating plate can be opened, and the outer wall of the pull plate 64 contacts the inner wall of the fixed post 62. The fixed post 62 restricts the movement range of the pull plate 64 to prevent the sliding post 63 from moving excessively and causing damage to the components. The top of the spring 66 is fixedly connected to... The bottom of the spring 66 is fixedly connected to the top of the convex plate 65, which is attached to the inner wall of the fixed column 62. This connection method allows the spring 66 to be compressed when the convex plate 65 moves, and the stored elastic potential energy can drive the sliding column 63 to automatically reset, realizing automatic locking. The cross-sectional shape of the connecting pipe 55 is trapezoidal. The trapezoidal structure allows the sealing plate 56 to gradually seal or open the connecting pipe 55 when it slides, realizing a smooth switching of water flow and preventing water leakage. The top of the fixed plate 67 is slidably connected to the bottom of the fixed column 62. The fixed column 62 provides support for the fixed plate 67, ensuring the stability of the fixed plate 67 and facilitating the accurate insertion and locking of the sliding column 63. The bottom of the fixed plate 67 is slidably connected to the outer wall of the base 61. The base 61 supports the fixed plate 67, enhances the stability of the fixed plate 67, and ensures reliable locking. Specifically, the convex plate 65 slides within the fixed post 62 to ensure the smooth movement of the sliding post 63 and reliable locking. The sliding post 63 penetrates the base 61 and cooperates with the fixed plate 67. When inserted, it locks the rotating plate, and when pulled out, it unlocks. The pull plate 64 contacts the fixed post 62 to limit the movement range of the sliding post 63 and prevent damage. The spring 66 connects the fixed post 62 and the convex plate 65. After compression and energy storage, it drives the sliding post 63 to automatically reset and lock. The trapezoidal connecting pipe 55 allows the sealing plate 56 to smoothly switch water flow and prevent water leakage. The fixed plate 67 slides at the bottom of the fixed post 62 against the outer wall of the base 61 to ensure accurate and reliable locking.

[0019] Working principle: The cylinder 52 on the inner wall of the barrel 51 is activated, causing the push plate 53 to slide along the inner wall of the barrel 51. This changes the air pressure inside the barrel 51. Thanks to the presence of the sliding plate 581 and the connecting rod 582, the two sealing plates 56 move towards or away from each other on the inner walls of the two connecting pipes 55. Due to the shape of the connecting pipes 55, when the two sealing plates 56 approach each other, one sealing plate 56 seals and blocks one connecting pipe 55, while the other sealing plate 56 and connecting pipe 55... The five phases are separated, allowing external water to enter the interior of the tank 51 through a water supply pipe 57. When the two sealing plates 56 are far apart, the other set of sealing plates 56 and the connecting pipe 55 are sealed together, allowing water inside the tank 51 to enter the transmission pipe 59 through another water supply pipe 57 and then into the humidifier water tank 2. This allows the water inside the humidifier water tank 2 to be replenished in stages, thus optimizing the problem of reduced service life of the entire maintenance box due to water shortage in the humidifier and significantly extending the service life of the entire maintenance box. Pulling the pull plate 64 causes the pull plate 64 to move the sliding column 63, which in turn causes the sliding column 63 to move the convex plate 65. The movement of the sliding column 63 releases the base 61 from locking the fixed plate 67, allowing the rotating plate 3 or the rotating plate 4 to rotate on one side of the housing 1. At the same time, the movement of the convex plate 65 compresses the spring 66, causing the spring 66 to undergo elastic deformation and generate elastic potential energy. The elastic potential energy of the spring 66 can push the convex plate 65 to drive the sliding column 63 back to its original position without the action of external force.
