Description

Technical Field

[0001] The invention belongs to the technical field of container bottom plates, and in particular relates to a fire-fighting spray device at the bottom of a container. Background Art

[0002] The greatest success of containers lies in the standardization of their products and the entire transportation system established on this basis, which can standardize a huge product with a load capacity of dozens of tons, and on this basis gradually realize a logistics system that matches ships, ports, routes, roads, transfer stations, bridges, tunnels, and multimodal transport around the world. This is indeed one of the greatest miracles ever created by mankind. The container is an internationally used multimodal transport tool, and its overall appearance is a hexahedral box structure, which mainly includes a bottom plate, two side walls connected to the horizontal sides of the floor, end walls and end doors connected to the longitudinal ends of the floor, and a top plate at the top. The floor, two side walls, end doors, end walls and top plate form a hexahedral box structure, and the container bottom plate is an important component of the container.

[0003] When transporting goods in containers, some goods have certain requirements for storage temperature. However, the existing container bottom plate cannot quickly control the temperature inside the container. In addition, when a fire occurs in the container, there is no fire-fighting equipment inside the container and the fire cannot be extinguished, resulting in poor practicality. Summary of the invention

[0004] The purpose of the present invention is to provide a fire-fighting spray device at the bottom of a container. The circulating pump transmits the water in the storage box through the installation three-way valve and the bent transmission pipe, and then transmits it to the connecting three-way valve through the installation pipe and the circulating pump, and then circulates it to the storage box for storage and recycling. In case of fire, the support plate and the transmission water pipe are pushed to move by the electric telescopic rod until the atomizing nozzle moves to the top of the sealing plate, and then the transmission pump is turned on. The transmission pump transmits the water in the storage box through the connecting pipe to the transmission water pipe, and then sprays it out through the atomizing nozzle to extinguish the fire in the container. The water can be recycled to save water resources. At the same time, the temperature control and fire fighting are combined to increase the practicality of the container bottom plate. By turning on the refrigeration pipe or the heating rod, the fire can be extinguished. Start the fixed motor, and the fixed motor rotates to drive the fixed gear to rotate. Through the transmission of the toothed belt, the two-way threaded rod can be rotated, and through the limiting of the limit rod, the movable plate can be moved, so that the installation rod drives the mixing plate to move, so that the water in the storage tank can be quickly cooled or heated. Then, the installation three-way valve and the connecting three-way valve will be opened to connect the installation three-way valve and the connecting three-way valve to the storage tank on one side connected to the refrigeration pipe or the heating rod. Then, the circulation pump will be turned on. The circulation pump will transfer the water in the cooling storage tank through the installation three-way valve and the curved transmission pipe, and then through the installation pipe and the circulation pump to the connecting three-way valve, and then circulate to the storage tank. At the same time, the circulation fan is turned on to blow the curved transmission pipe, which can quickly cool down or heat up the container.

[0022] A manufacturing process of a fire-fighting spray device at the bottom of a container, comprising the following steps:

[0023] Step 1: Make the container bottom plate: open a mounting groove on the top of the box, install the fire-fighting mechanism, water transmission mechanism, circulating temperature control mechanism and uniform mechanism in the box, and then seal the box with a sealing plate to complete the container bottom plate;

[0024] Step 2: Temperature control of the container floor: When it is necessary to cool the inside of the container, turn on the refrigeration pipe and the fixed motor. The rotation of the fixed motor drives the fixed gear to rotate. Through the transmission of the toothed belt, the bidirectional threaded rod can be rotated. With the limitation of the limiting rod, the moving plate can be moved, so that the mounting rod drives the mixing plate to move, quickly cooling the water in the storage tank. Then turn on the mounting three-way valve and the connecting three-way valve, so that the mounting three-way valve and the connecting three-way valve are connected to the storage tank on the side connected with the refrigeration pipe. Then turn on the circulation pump. The circulation pump transports the water in the storage tank through the mounting three-way valve and the bent transmission pipe, and then through the mounting pipe and the circulation pump to the connecting three-way valve, and then circulates back to the storage tank. At the same time, turn on the circulation fan to blow the bent transmission pipe, so that the cold air enters the container through the sealing plate for cooling. When it is necessary to heat the inside of the container, turn on the heating rod, and then turn on the mounting three-way valve and the connecting three-way valve, so that the mounting three-way valve and the connecting three-way valve are connected to the storage tank on the side connected with the heating rod. Through the above steps, the hot air can enter the container through the sealing plate for heating;

[0025] Step 3: Fire fighting: When a fire breaks out, the electric telescopic rod pushes the support plate and the transmission water pipe to move until the atomizing nozzle moves to the top of the sealing plate. Then turn on the transmission pump. The transmission pump transports the water in the storage tank through the connecting pipe to the transmission water pipe, and then sprays it out through the atomizing nozzle to extinguish the fire in the container;

[0026] Step 4: Supplementary water source: When it is necessary to supplement water to the storage tank, the user first opens the sealing cover, and then transports the water to the storage tank through the connecting pipe for storage.

[0027] Step 5: Loading and unloading goods: When it is necessary to take out goods from the container, hydraulic oil is pumped into the main liquid inlet pipe through an external liquid pump; the hydraulic oil is pumped into each hydraulic cavity through each liquid inlet branch pipe, pushing the upper piston and the lower piston to move away from each other. Since the main support roller on the lower push rod abuts against the support arc surface, the lower push rod cannot move. Therefore, only the upper push rod can move upward. The upper push rods of each jacking sliding mechanism jointly push the container floor composed of the box body to rise; during this process, the auxiliary support mechanism provides additional auxiliary support force; the triangular structure formed by it and the jacking sliding mechanism has stability; when the container floor composed of the box body is jacked up until it is separated from the inner structure floor of the container body, the container floor composed of the box body is pulled outwards by a trailer or a pulley mechanism outside. Due to the rolling action of the main support roller and the auxiliary support roller, the container floor can be pulled out of the container body relatively smoothly and easily, thus facilitating unloading.

[0028] During loading, pull out the container floor plate from the container body as described above. Then, place the goods or equipment on the container floor plate and fix them. Next, cover the goods with a tarpaulin. Snap the clamping blocks on the four sides of the tarpaulin respectively into the card slots on the winding rollers on the four sides of the container floor plate. Then, start the torque motor. The torque motor drives the second gear to rotate, thereby driving the first gear to rotate, and then driving the winding roller to rotate and wind, so as to tension the tarpaulin. On the one hand, it can utilize the high strength and tension of the tarpaulin to assist in fixing the goods or equipment. On the other hand, it plays a shielding role and can prevent water dripping or leaking from above from attacking the goods or equipment.

[0029] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows:

[0030] (1) The present invention has the following beneficial effects:

[0031] 1. Temperature control: The container floor plate has a circulating temperature control mechanism, including a temperature regulating component, a heating rod, and a refrigeration pipe. The temperature regulating component can adjust the water temperature. The heating rod is used for heating, and the refrigeration pipe is used for cooling. By controlling the circulation pump and the circulation fan, the circulating transmission of water and the circulating convection of air can be realized, so as to achieve precise control of the temperature inside the container.

[0032] 2. Fire extinguishing: The fire-fighting mechanism includes a pushing component, a connecting component, and an atomizing nozzle. When a fire occurs, the pushing component moves the atomizing nozzle to the top of the sealing plate, and water is sprayed into the container interior through the atomizing nozzle by the transfer pump to achieve rapid and effective fire extinguishing.

[0033] 3. Water source replenishment: The water transmission mechanism includes a transmission water pipe, a transfer pump, and a connecting pipe. Through the connecting pipe, the water source can be conveniently replenished into the storage tank. After opening the sealing cover, water can be transmitted into the storage tank through the connecting pipe for storage and use.

[0034] 4. Uniform heating or cooling: The moving component includes a bidirectional threaded rod, a limiting rod, a moving plate, a mounting rod, and a mixing plate. By controlling the power component, the bidirectional threaded rod rotates, and the position of the moving plate can be adjusted. Through the cooperation of the mounting rod and the mixing plate, a uniform heating or cooling effect can be achieved, ensuring a uniform temperature distribution inside the container.

[0035] 5. Stable structure: The container floor plate is composed of a box body and a sealing plate, and various functional modules are fixedly connected, such as a fire-fighting mechanism, a water transmission mechanism, and a circulating temperature control mechanism. This structure ensures the integrity and stability of the bottom, can withstand the vibration and external pressure during transportation, and ensures the normal operation of the functional components.

[0036] With the above functions and features, the temperature-controlled container floor and its manufacturing process can be widely applied to scenarios where temperature control and protection of goods are required, such as the transportation and storage of temperature-sensitive items like food, pharmaceuticals, and chemicals. It can ensure that the goods remain within the required temperature range throughout the transportation process, thereby maintaining the quality and safety of the goods. In addition, this technical solution also has flexibility and customizability, and can be adjusted and improved according to actual needs.

[0037] 6. Convenient loading and unloading: The container floor can be lifted by the lifting and sliding mechanism, so that the bottom of the container floor is separated from the inner structure floor of the container. Thus, by utilizing the rolling ability of the main support rollers and the auxiliary support rollers, the container floor can be conveniently pulled out as a whole. On the one hand, it can facilitate the loading and unloading of goods, and on the other hand, it can improve the utilization rate of the container height. Especially for whole-piece equipment goods, in the past, the way to load and unload goods in a container required a forklift to fork the goods into or out of the container. During this process, the goods needed to be tilted on the fork rod, and there were limitations on the height of the forklift. Therefore, it was extremely inconvenient to load and unload goods that were relatively high but still lower than the inner height of the container and heavy, and it was also easy to damage the goods. Moreover, after loading and unloading the goods, workers needed to fix and untie them inside the container, which required operating space and further reduced the utilization rate of the container. With the lifting and sliding mechanism and the auxiliary support mechanism, the goods can be loaded and unloaded outside the container, making it more convenient to load and unload goods. Especially in the case of heavy or large goods, this lifting and sliding mechanism can greatly save manpower and time and improve the space utilization rate of the container. The lifting and sliding mechanism is inclined and cooperates with the support arc surface at the corner of the long bottom edge inside the container by using the main support rollers, enabling smooth and accurate lifting and lowering actions. On this basis, adding an auxiliary support mechanism can further improve the stability and safety of the equipment.

[0038] 7. Waterproof and dustproof: Tensioning mechanisms are provided on the four sides of the container floor, which can effectively fix the tarpaulin to protect the goods loaded in the container. In this way, the movement of the goods during transportation can be avoided, and at the same time, damage to the goods caused by external environmental factors (such as rain, dust, water leaking from the upper container, etc.) can be prevented. The tensioning mechanism driven by a torque motor can conveniently and quickly tension and loosen the tarpaulin, and the tensioning force of the tarpaulin can be adjusted, ensuring the stability and protection of the tarpaulin when loading different types and sizes of goods. The design of the winding roller makes the retraction and deployment of the tarpaulin more convenient and fast. At the same time, the design of the card slots and the clamping blocks can simply, quickly, and effectively fix and disassemble the tarpaulin, significantly improving the operation efficiency.

[0071] The following provides a detailed description of a fire spray device at the bottom of a container provided by an embodiment of the present invention, and its manufacturing process includes the following steps: Step 1, manufacturing the container bottom plate: Open an installation groove at the top of the box body 1, install the fire-fighting mechanism 3, water transmission mechanism 4, circulation temperature control mechanism 5, and uniform mechanism 6 inside the box body 1, and then seal the box body 1 with the sealing plate 2 to complete the manufacturing of the container bottom plate; Step 2, temperature control of the container bottom plate: When it is necessary to cool the inside of the container, turn on the refrigeration pipe 505, turn on the fixed motor 601, the rotation of the fixed motor 601 drives the rotation of the fixed gear 602, through the transmission of the toothed belt, the bidirectional threaded rod 604 can be rotated, and through the limit of the limit rod 605, the moving plate 606 can be moved, so that the installation rod 607 drives the mixing plate 608 to move, quickly cooling the water in the storage tank 501. Then turn on the installation three-way valve 506 and the connection three-way valve 507 to connect the installation three-way valve 506 and the connection three-way valve 507 to the storage tank 501 on the side connected to the refrigeration pipe 505.

[0074] In addition, an auxiliary support mechanism 8 is further arranged on one side of the lifting and sliding mechanism 7 close to the box body 1; the auxiliary support mechanism 8 includes a vertically arranged support column 801; the upper end of the support column 801 is fixedly connected to an extension body 802 extending outwards from the cylindrical hydraulic cylinder 701, and a secondary support roller 803 is fixed at the lower end; the secondary support roller 803 rolls and supports on the inner structural floor of the container body 10; the position of the inner structural floor of the container body 10 corresponding to the secondary support roller 803 is subjected to planar filling treatment.

[0075] In addition, a plurality of tensioning mechanisms 9 for tensioning the tarpaulin 11 for covering goods are respectively arranged at the four side positions of the whole container floor; a long groove 901 is opened in the middle of the outer side of the box body 1 that constitutes the outermost periphery of the container floor, and extension parts 908 are formed at both ends thereof; the tensioning mechanism 9 includes a winding roller 902 arranged in the long groove 901; both ends of the winding roller 902 are respectively rotatably connected to the extension parts 908 on both sides of the long groove 901 and are supported by the extension parts 908; a first gear 903 is fixedly sleeved at one end or both ends of the winding roller 902 to be rotationally linked with the winding roller 902; a second gear 904 meshes with the first gear 903; the second gear 904 is driven to rotate by a torque motor 905; clamping grooves 906 are respectively opened at positions close to the outer circumference at both ends of the winding roller 902; clamping blocks 907 detachably fitted with the clamping grooves 906 are respectively connected to the positions of the tarpaulin 11 corresponding to the clamping grooves 906.

[0076] The working method is as follows: when it is necessary to take out the goods from the container, hydraulic oil is pumped into the main liquid inlet pipe 706 through an external liquid pump; the hydraulic oil is pumped into each hydraulic cavity 704 through each liquid inlet branch pipe 705, pushing the upper piston 702 and the lower piston 703 away from each other. Since the main support roller 709 on the lower push rod 708 abuts against the support arc surface 710, the lower push rod 708 cannot move. Therefore, only the upper push rod 707 can move upward, and the upper push rods 707 of each jacking sliding mechanism 7 jointly push up the container floor composed of the box body 1; during this process, the auxiliary support mechanism 8 provides additional auxiliary support force; the triangular structure formed by it and the jacking sliding mechanism has stability.

[0077] When the container floor composed of the box body 1 is jacked up until it is separated from the inner structure floor of the container body 10, the container floor composed of the box body 1 is pulled outwards by a trailer or a pulley mechanism outside. Due to the rolling action of the main support roller 709 and the auxiliary support roller 803, the container floor can be pulled out of the container body 10 more smoothly and easily, thus facilitating unloading.

[0078] When loading goods, the container floor is pulled out of the container body 10 as described above. Then, the goods or equipment are placed on the container floor and fixed. Then, a tarpaulin 11 is covered on the goods; the clamping blocks 907 on the four sides of the tarpaulin 11 are respectively clamped with the card slots 906 on the winding rollers 902 on the four sides of the container floor; then the torque motor 905 is started, and the torque motor 905 drives the second gear 904 to rotate, thereby driving the first gear 903 to rotate, and then driving the winding roller 902 to rotate and wind, so as to tension the tarpaulin 11. On the one hand, the high strength and tension of the tarpaulin can be used to assist in fixing the goods or equipment, and on the other hand, it plays a role in shielding, which can prevent water dripping or leaking from above from invading the goods or equipment.

[0079] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
