Description

Technical Field

[0001] This utility model belongs to the field of construction engineering technology, specifically relating to a large-volume concrete cooling robot. Background Technology

[0002] Cement in concrete reacts with water to form hydration products; this process is called hydration. Hydration is exothermic, meaning it releases heat during the reaction, causing the internal temperature of the concrete to rise and generating thermal stress, which can lead to cracking. Currently, the common method for temperature control is to manually spray cooling water. By sprinkling water on the concrete surface, the surface temperature can be lowered, reducing the temperature difference between the inside and outside of the concrete, thus reducing cracking caused by thermal stress. However, this method is inefficient and difficult to control precisely. To improve the efficiency of watering the concrete surface, for example, a Chinese patent discloses a concrete cooling device (patent publication number: CN221896261U). This device uses a water tank filled with cooling water, and a first drive mechanism drives the base to move, causing the entire device to move across the concrete surface to be cooled. A second drive mechanism can adjust the angle of the atomizing nozzles, effectively increasing the spray range of the cooling water and eliminating the need for a water source, offering greater convenience.

[0003] While the above-mentioned technical solution can effectively solve the current problem of heat dissipation on the outer surface of concrete, during use, construction workers need to move the base to spray cooling water on the concrete surface. Furthermore, since the heat-generating areas on the concrete surface cannot be directly detected, construction workers usually spray cooling water on the entire concrete surface, which is not only time-consuming and labor-intensive but also wastes water resources. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a large-volume concrete cooling robot to solve the problem that the current method of spraying coolant onto the surface of concrete cannot achieve precise spraying based on the heat-generating location of the concrete surface.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A large-volume concrete cooling robot includes a base, a moving component disposed on the lower surface of the base, and a frame body disposed on the base. The moving component includes drive wheels and steering wheels for providing power. A water tank for holding coolant is installed on the frame body. A water pump connected to the water tank is fixed on the frame body, and the output end of the water pump is connected to a spraying mechanism for spraying cooling water onto the concrete surface. The spraying mechanism is disposed on the lower surface of the base. A first temperature sensor for detecting the concrete surface temperature is also installed on the frame body. The first temperature sensor, the moving component, and the water pump are electrically connected to a controller. The controller is disposed inside the frame body and is also electrically connected to a wireless communication module, which remotely controls the movement of the moving component.

[0007] Furthermore, the spraying mechanism includes a support housing mounted on the vehicle frame body and multiple swing blades movably mounted on the support housing. Each swing blade is arranged in a horizontal array along the length direction of the support housing. Both ends of each swing blade are rotatably connected to the support housing. The support housing is provided with a drive component for driving each swing blade to reciprocate synchronously. The drive component is electrically connected to a controller. Each swing blade has a nozzle fixed on its surface that is connected to the output end of a water pump.

[0008] Furthermore, the water storage tank is equipped with a refrigeration device for cooling the coolant, and the refrigeration device is electrically connected to the controller.

[0009] Furthermore, the surface of the vehicle frame body is provided with a lidar that is electrically connected to the controller, and the lidar is installed at the front of the vehicle frame body when it moves.

[0010] Furthermore, the water storage tank is equipped with a second temperature sensor and a liquid level sensor, both of which are electrically connected to the controller.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses a moving component at the bottom of the chassis to move the water tank. Then, a first temperature sensor detects the temperature of the concrete surface and compares it with preset data in the controller. When the temperature of the concrete surface is higher than the preset threshold, the controller will control the moving component to move the chassis to the concrete that needs to be cooled. Then, the water pump will control the water pump to spray the coolant in the water tank evenly onto the concrete surface through the nozzle. This can achieve precise cooling based on the heat source of the concrete surface, effectively improving construction efficiency while saving water resources.

[0013] Other advantages, objectives, and features of this invention will be set forth in the following description and will be apparent to those skilled in the art to some extent, or may be learned by practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

[0020] like Figures 1-3 As shown,

[0021] A large-volume concrete cooling robot includes a base 1, a moving component 2 disposed on the lower surface of the base 1, and a frame body 3 disposed on the base 1. The moving component 2 includes drive wheels 202 and steering wheels 201 for providing power (of course, the steering wheels 201 are also powered by a drive motor for rotating them; the specific working principle is prior art and will not be elaborated here). A water tank 4 for holding coolant is installed on the frame body 3. A water pump (not shown in the figure) connected to the water tank 4 is bolted to the frame body 3, and the output end of the water pump is connected to a spraying mechanism 5 for spraying cooling water onto the concrete surface. The spraying mechanism 5 is located on the lower surface of the base 1. The main body of the vehicle frame 3 is also equipped with a first temperature sensor 6 for detecting the temperature of the concrete surface (the first temperature sensor 6 can be a thermal imager, which can measure the temperature distribution over a large area of ​​the concrete surface). The first temperature sensor 6 is located at the front of the main body of the vehicle frame 3 when it moves. The first temperature sensor 6, the moving component 2, and the water pump are electrically connected to a controller. The controller is located inside the main body of the vehicle frame 3 and is also electrically connected to a wireless communication module (the wireless communication module can use existing wireless transmission technologies such as Wi-Fi and 5G). The controller can remotely control the movement of the moving component 2 through the wireless communication module.

[0022] As shown in the diagram, when cooling a portion of the concrete surface is required, the water tank 4 is first filled with cooling water. Then, the moving component 2 is remotely controlled to move via a wireless communication module and controller. During the movement of the chassis body 3, the first temperature sensor 6 detects the temperature of the concrete surface that the chassis body 3 is about to pass over. When the temperature of a portion of the concrete surface is detected to be higher than the preset threshold in the controller, the controller starts the water pump. The water pump delivers the cooling water from the water tank 4 to the spraying mechanism 5 and sprays it onto the concrete surface, thereby cooling the overheated areas of the concrete surface. Based on the moving speed of the chassis body 3 and the area of ​​the overheated concrete surface detected by the first temperature sensor 6, the controller can adjust the spraying time of the water pump to ensure that the coolant sprayed by the spraying mechanism 5 can cover the overheated areas of the concrete surface during the movement of the chassis body 3. This achieves precise area spraying and cooling, effectively reducing the burden on construction personnel. Only the movement of the chassis body 3 needs to be remotely controlled to cool the concrete surface, eliminating the need to spray coolant onto the entire concrete surface, thus reducing water waste to a certain extent.

[0023] In this embodiment, the spraying mechanism 5 includes a support housing 501 mounted on the vehicle frame body 3 and a plurality of swing blades 502 movably mounted on the support housing 501. Each swing blade 502 is arranged in a horizontal array along the length direction of the support housing 501, and each swing blade 502 is vertically arranged. Both ends of each swing blade 502 are rotatably connected to the support housing 501 along its length direction. The support housing 501 is provided with a drive component for driving each swing blade 502 to reciprocate synchronously in the vertical plane. The drive component is electrically connected to a controller. Each swing blade 502 has a plurality of nozzles 503 fixed on its surface, which are connected to the output end of a water pump. Each nozzle 503 is staggered along the length direction of the swing blade 502 in the horizontal plane.

[0024] As shown in the figure, when the main body 3 of the vehicle frame passes over the concrete surface that needs to be cooled, the controller activates the drive unit that drives each swing blade 502 and the water pump. The water pump delivers the coolant in the water tank 4 to each nozzle 503 for spraying. At the same time, each swing blade 502 swings back and forth in the vertical plane under the drive unit. The drive unit can use a drive motor and a gear rack to achieve synchronous swinging of each swing blade 502 (the gear is set on the rotating shaft of the swing blade, and its specific implementation principle is existing technology, which will not be elaborated here). This can effectively improve the spraying range of each nozzle 503 and reduce the dead angle of coolant spraying.

[0025] In this embodiment, the water storage tank 4 is equipped with a refrigeration device for cooling the coolant, and the refrigeration device is electrically connected to the controller. The refrigeration device can be a semiconductor refrigeration block, which can maintain the temperature of the coolant in the water storage tank 4 under high temperature environment and ensure the cooling effect of the coolant.

[0026] In this embodiment, the surface of the vehicle frame body 3 is provided with a lidar 7 electrically connected to the controller, and the lidar 7 is installed at the front of the vehicle frame body 3 when it moves.

[0027] The lidar 7 can detect the environmental conditions around the vehicle frame 3. In conjunction with the controller and the first stabilization sensor, it can achieve automatic obstacle avoidance and automatically find the location of the concrete surface that needs to be cooled. It can also draw a three-dimensional graphic of the concrete surface based on the road conditions, and then automatically cool down a part of the concrete surface, which can further improve the intelligence and automation of this utility model.

[0028] In this embodiment, the water storage tank 4 is equipped with a second temperature sensor and a liquid level sensor, both of which are electrically connected to the controller, which can monitor the temperature of the coolant and the remaining amount of coolant in the water storage tank 4 in real time.

[0029] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
