Description

Technical Field

[0001] This utility model relates to the field of dust suppression and cooling devices, and in particular to a dust suppression and cooling spray device for construction sites. Background Technology

[0002] In the construction environment of building sites, a large amount of dust is easily generated in the work area. Simultaneously, the temperature in the construction area is high during peak hours, which not only affects the comfort and health of workers but also easily causes dust pollution in the surrounding environment. Therefore, dust suppression and cooling devices are commonly used auxiliary equipment on construction sites. However, some problems exist in existing technologies: Firstly, most existing dust suppression and cooling devices at construction sites directly use ambient temperature water for spraying, relying solely on the basic specific heat capacity of water to achieve cooling. The cooling effect is relatively limited, and it is impossible to enhance the cooling effect by using low temperature water, making it difficult to achieve a highly efficient cooling effect.

[0003] Secondly, most existing dust suppression and cooling devices at construction sites are fixed-height spray structures. The spray height is difficult to cover the height of workers and the height of dust commonly seen at construction sites, resulting in a limited dust suppression range. This makes it difficult to effectively contain and settle dust, and thus difficult to achieve efficient dust suppression.

[0004] Therefore, there is an urgent need to design a dust suppression and cooling spray device for construction sites that can solve the above technical problems. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a dust suppression and cooling spray device for construction sites to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model mainly provides the following technical solutions: A dust suppression and cooling spraying device for construction sites includes a transport vehicle and further includes: Water storage and cooling mechanism and lifting spray mechanism; wherein: The water storage and cooling mechanism includes a water storage component and a cooling component respectively located on the middle and right side of the upper part of the transport flatbed vehicle; The lifting and spraying mechanism includes lifting components and spraying components respectively located on the left and right sides above the transport vehicle.

[0007] Furthermore, the water storage assembly includes a water storage tank mounted on the middle of the upper surface of the transport vehicle via a support frame; The water storage tank has a water inlet hole and a cleaning door on the left and right sides of its upper surface, respectively. The upper end of the water inlet hole is threaded with a dust cover, and the lower end is equipped with a filter screen. The inner circumferential wall of the water storage tank is provided with a heat insulation layer, a thermometer is provided in the middle of the inner bottom wall, and a water outlet is opened through the front side. A transparent viewing window is provided on the front side of the outer wall of the water storage tank.

[0008] Furthermore, the refrigeration assembly includes a waterproof frame on the right side of the upper surface of the transport vehicle. The waterproof frame is divided into upper and lower layers. A refrigeration compressor is located in the middle of the upper layer of the waterproof frame. A cooling fan is located in front of the refrigeration compressor. A refrigeration pipe is connected to the left side. The middle section of the refrigeration pipe passes through the right side wall of the water storage tank and is attached and wrapped around the inner circumferential wall of the insulation layer.

[0009] Furthermore, the lifting assembly includes a base on the left side of the upper surface of the transport vehicle, a support rod and a telescopic rod above the base, a hydraulic pump inside the support rod, and the output end of the hydraulic pump being fixedly connected to the telescopic rod; The upper end of the telescopic rod is horizontally connected to the spray rod.

[0010] Furthermore, the spray assembly includes a folded hose inside the lifting assembly and multiple atomizing nozzles on the outer periphery of the spray rod; The lower layer of the waterproof frame is equipped with a centrifugal water pump. One end of the centrifugal water pump is connected to the water outlet through a water suction pipe, and the other end is connected to one end of a folded hose through a drain pipe. The other end of the folded hose is connected to multiple atomizing nozzles. Furthermore, a control panel is provided on the outer side of the upper end of the support rod, and a fixing bracket is fixedly installed in the middle section; The control panel surface is equipped with a display screen and control buttons; The movable sleeve on the right side of the fixing frame is engaged with the outer perimeter of the water storage tank.

[0011] Furthermore, the transport vehicle is equipped with a push-pull handle on the left side, universal wheels at the four corners of the lower surface, and a drainage groove through the inner bottom wall.

[0012] Furthermore, waterproof plates are movably mounted on all sides of the waterproof frame via pivots.

[0013] Compared with the prior art, the beneficial effects of this utility model are mainly reflected in: Firstly, compared to existing dust suppression and cooling devices for construction sites that directly use ambient temperature water spray, the cooling effect is limited. To solve this problem, this utility model proposes a water storage and cooling spray device for construction sites. It stores water through a water storage component, and works with a refrigeration compressor and refrigeration pipes in the cooling component to cool the water. Simultaneously, the insulation layer inside the water storage tank maintains the water at a low temperature, ensuring a continuous and stable supply of low-temperature spray water, thus enhancing the cooling effect and improving work comfort in high-temperature construction environments.

[0014] Secondly, compared to existing dust suppression and cooling devices for construction sites that use a fixed-height spray structure and have a limited dust suppression range, this utility model proposes a dust suppression and cooling spray device for construction sites that employs a lifting spray mechanism. The hydraulic pump of the lifting component drives a telescopic rod to adjust the spray height, covering the height of workers and common dust levels on construction sites. Combined with the atomizing nozzles of the spray component, this expands the dust suppression coverage area, effectively encapsulating and settling dust, thus improving dust suppression efficiency.

Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0017] like Figure 1-4 As shown, this utility model discloses a dust suppression and cooling spray device for construction sites, including a transport cart 1. The transport cart 1 serves as a load-bearing base for the various components of the device, providing a stable support platform for the subsequent installation of the mechanism, and facilitating the overall movement and transportation of the device. It also includes: Water storage and cooling mechanism 2 and lifting spray mechanism 3; wherein: The water storage and cooling mechanism 2 includes a water storage component 21 and a cooling component 22 respectively located on the middle and right side of the upper part of the transport vehicle 1. The water storage and cooling mechanism 2 is responsible for storing and treating the water source at low temperature. The water storage component 21 is used to store the water source required for spraying, and the cooling component 22 is used to cool the water source in the water storage component 21. The lifting spray mechanism 3 includes a lifting component 31 and a spray component 32 respectively located on the left and right sides above the transport vehicle 1. The lifting spray mechanism 3 is used to adjust the spray height and spray the dust and cooling medium. The lifting component 31 is responsible for adjusting the height of the spray component, and the spray component 32 completes the atomization and spraying of low temperature water.

[0018] like Figure 3 , 4 As shown, in this embodiment, the water storage component 21 includes a water storage tank 211 installed on the middle of the upper surface of the transport vehicle 1 via a support frame 11, which can stably mount the water storage tank 211 above the transport vehicle 1, facilitating the subsequent connection of the water outlet 218 to the water pump pipeline. Water inlet 212 and cleaning door 213 are respectively opened on the left and right sides of the upper surface of the water storage tank 211. The water inlet 212 is used to replenish water into the water storage tank 211. The cleaning door 213 can be opened after the water storage tank 211 has been used for a long time, so that the operators can clean the residual impurities and scale in the tank and ensure the cleanliness of the stored water. The upper end of the water inlet 212 is threaded with a dust cover 214, which facilitates the quick installation and removal of the dust cover 214. It can also seal the water inlet 212 when water is not added, preventing external dust, sand and other debris from entering the water storage tank 211 through the water inlet 212 and contaminating the water source. The lower end is equipped with a filter screen 215, which can perform preliminary filtration of the water source injected through the water inlet 212, intercepting impurities such as mud and sand and particulate matter in the water, and preventing impurities from entering the water storage tank 211 and clogging the subsequent pipes or nozzles. The inner circumferential wall of the water storage tank 211 is provided with a heat insulation layer 216, which can reduce the heat exchange between the low temperature water source in the water storage tank 211 and the external environment, slow down the rate of water source heating, ensure a continuous supply of low temperature water during the spraying process, and maintain a good cooling effect. A thermometer 217 is provided in the middle of the inner bottom wall, which can monitor the temperature of the water source in the water storage tank 211 in real time and feed the temperature data back to the control panel 12, so that the operators can keep track of the water source temperature status in a timely manner. A water outlet hole 218 is opened through the front side to ensure that the water source in the water storage tank 211 can be fully drained to avoid residual water accumulation. The water storage tank 211 has a transparent window 219 on the front of its outer wall, which allows operators to directly observe the remaining water in the water storage tank 211 and determine whether water needs to be added without opening the device, thus improving the convenience of operation.

[0019] like Figure 2 , 4As shown, in this embodiment, the refrigeration component 22 includes a waterproof frame 221 on the right side of the upper surface of the transport vehicle 1, which protects the internal refrigeration components from rainwater, spray mist, and other environmental factors that could damage them. The waterproof frame 221 has upper and lower layers, and this layered design allows for the separate installation of components with different functions, preventing interference between components and improving space utilization. A refrigeration compressor 222 is located in the middle of the upper layer of the waterproof frame 221, which generates a cooling effect by compressing refrigerant to provide a low temperature for cooling the water in the water storage tank 211. A cooling fan 223 is located on the front side of the refrigeration compressor 222, which can dissipate heat from the refrigerant. The heat generated during the operation of the compressor 222 is dissipated in a timely manner to prevent the compressor from reducing its working efficiency or being damaged due to overheating, thus ensuring the stable operation of the refrigeration component 22. The left side is connected to the refrigeration pipe 224, which can transport the low temperature generated by the refrigeration compressor 222 to the inside of the water storage tank 211 to achieve cooling of the water source. The middle section of the refrigeration pipe 224 passes through the right side wall of the water storage tank 211 and is closely wrapped around the inner circumferential wall of the insulation layer 216. This can increase the contact area between the refrigeration pipe 224 and the water source in the water storage tank 211, improve the efficiency of cold energy transfer, and allow the water source to be cooled to the target temperature more quickly. At the same time, the winding structure can also make full use of the internal space of the water storage tank 211 and avoid the refrigeration pipe 224 being distributed haphazardly.

[0020] like Figure 1 , 2 As shown in Figure 4, in this embodiment, the lifting assembly 31 includes a base 311 on the left side of the upper surface of the transport vehicle 1. The base 311 can provide stable bottom support for the subsequent components of the lifting assembly 31, enhance the overall structural stability of the lifting assembly 31, and prevent swaying or tipping during the lifting process. A support rod 312 and a telescopic rod 313 are provided above the base 311. The support rod 312 serves as a fixed support structure for the lifting assembly 31 and provides guidance and limit for the telescopic movement of the telescopic rod 313. The telescopic rod 313 can adjust its own length by telescopic movement, thereby adjusting the height of the spray component. A hydraulic pump 314 is provided inside the support rod 312. The hydraulic pump 314 can provide stable power output to drive the telescopic rod 313 to complete the telescopic movement. The output end of the hydraulic pump 314 is fixedly connected to the telescopic rod 313 to ensure that the power of the hydraulic pump 314 can be directly and efficiently transmitted to the telescopic rod 313. The upper end of the telescopic rod 313 is horizontally connected to the spray rod 315, and the spray rod 315 is stably fixed to the upper end of the telescopic rod 313 to ensure that the spray rod 315 will not shift or fall during the spraying process.

[0021] like Figure 1 , 4As shown, in this embodiment, the spray assembly 32 includes a folded hose 321 inside the lifting assembly 31. The folded hose 321 has the characteristics of being retractable and flexible, and can extend and deform synchronously with the lifting action of the telescopic rod 313. It does not restrict the movement of the telescopic rod 313, and can maintain the continuous connection of the water channel. The spray rod 315 is provided with multiple atomizing nozzles 322 on its outer periphery. The multiple atomizing nozzles 322 are evenly distributed on the outer periphery of the spray rod 315, which can atomize the delivered low temperature water into fine water mist, increase the contact area between the water mist and the air and dust, improve the dust reduction and cooling effect, and expand the coverage of the spray. The lower layer of the waterproof frame 221 is equipped with a centrifugal water pump 323. The centrifugal water pump 323 can generate sufficient pressure to transport the low-temperature water source in the water storage tank 211 to the spraying component through the pipeline, which can ensure that multiple nozzles spray stably at the same time. One end of the centrifugal water pump 323 is connected to the water outlet 218 through the water suction pipe 324. The water suction pipe 324 serves as the channel for water to flow from the water storage tank 211 to the centrifugal water pump 323. The other end is connected to one end of the folded hose 321 through the drain pipe 325. The drain pipe 325 is used to transport the water source pressurized by the centrifugal water pump 323 to the folded hose 321. The other end of the folded hose 321 is connected to multiple atomizing nozzles 322 respectively. The structure of the folded hose 321 connected to multiple atomizing nozzles 322 can synchronously distribute the water source to each nozzle, ensuring that each nozzle can obtain sufficient water and achieve uniform spraying. like Figure 1 As shown, in this embodiment, the upper outer side of the support rod 312 is provided with a control panel 12, which is located at a height that is convenient for operators to operate, so that operators can adjust and control the operating status of the device at any time. The middle section is fixedly installed with a fixing frame 13, which can connect the support rod 312 and the water storage tank 211 into a whole, enhance the connection stability between the components of the device, and prevent the components from becoming loose during the movement or operation of the device. The control panel 12 is equipped with a display screen 121 and control buttons 122. The display screen 121 can intuitively display the operating parameters of the device, such as water source temperature and equipment operating status. The control buttons 122 are used to start, stop and adjust the various functions of the device. The movable sleeve on the right side of the fixing frame 13 is attached to the outer periphery of the water storage tank 211, which can not only connect and fix the support rod 312 to the water storage tank 211, but also does not restrict the disassembly and maintenance of the water storage tank 211, thus improving the ease of maintenance of the device.

[0022] like Figure 1 , 3As shown, in this embodiment, the left side of the transport cart 1 is provided with a push-pull handle 14, which is convenient for operators to hold. By pushing or pulling the handle, the device can be easily moved, adapting to the usage needs of different work areas on the construction site. The four corners of the lower surface are provided with casters 15, which have the characteristic of flexible steering, allowing the device to move freely in the complex ground environment of the construction site, improving the flexibility of the device. The inner bottom wall is provided with a drainage groove 16, which can drain the residual water on the transport cart 1 in time, preventing water from accumulating on the transport cart 1 and preventing water from soaking the device components or causing the ground to be slippery and affecting the operation.

[0023] like Figure 1 , 2 As shown, in this embodiment, the waterproof frame 221 is movably mounted with waterproof plates 18 on all sides via pivots 17. The waterproof plates 18 can be opened and closed flexibly. When the device is running, the waterproof plates 18 can be opened to facilitate heat dissipation. When the device is idle or in rainy weather, the waterproof plates 18 can be closed to further enhance the protection of the internal components of the waterproof frame 221 and prevent the components from being corroded by the external environment.

[0024] The working principle and usage process of this technical solution are as follows: During use, firstly, the device is moved to the target work area using the push-pull handle 14 and the universal wheels 15; then, the dust cover 214 of the water storage tank 211 is opened, and water is injected into the water storage tank 211 through the water inlet 212. The filter screen 215 at the bottom will simultaneously intercept impurities in the water to ensure the cleanliness of the water source; after the water source is injected, the dust cover 214 is closed. Then, the refrigeration component 22 is started through the control button 122 on the control panel 12, and the refrigeration compressor 222 starts working, generating cooling capacity by compressing the refrigerant. The cooling capacity is transferred to the water source in the water storage tank 211 through the refrigeration pipe 224, allowing the water source to cool down quickly; at the same time, the insulation layer 216 inside the water storage tank 211 will reduce heat exchange, and the thermometer 217 monitors the water temperature in real time and displays the data on the control panel 12. On the display screen 121, it is convenient for operators to keep track of the cooling progress. After the water temperature reaches the target value, the control button 122 on the control panel 12 is used to adjust the hydraulic pump 314 of the lifting component 31. The hydraulic pump 314 outputs power to drive the telescopic rod 313 to extend and retract until the spray rod 315 reaches a suitable position that can cover the height of the operator and the height of the dust. Then, the centrifugal water pump 323 is started. The low temperature water source in the water tank 211 flows into the water pipe 324 through the water outlet 218. After being pressurized by the centrifugal water pump 323, it is delivered to the folded hose 321 through the drain pipe 325. Finally, the low temperature water source is distributed to multiple atomizing nozzles 322 on the spray rod 315 through the folded hose 321. The nozzles atomize the water source into fine water mist and spray it onto the working area, increasing the contact area between the water mist and the dust and air, and efficiently achieving dust reduction and cooling. During use, operators can observe the remaining water level at any time through the transparent window 219 of the water storage tank 211 and replenish water as needed. If impurities accumulate inside the water storage tank 211, the cleaning door 213 can be opened for cleaning to ensure the quality of the stored water. When the device is running, the waterproof plate 18 of the waterproof frame 221 can be opened and closed according to the environmental conditions. The drain trough 16 on the bottom wall of the transport vehicle 1 will drain the water dripping during the spraying process in time. After the operation is completed, turn off the function buttons on the control panel 12, and then move the device to the designated storage area by pushing and pulling the handle 14 to complete the entire usage process.

[0025] The present invention has been further described above with reference to the embodiments, but the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
