Description
Technical Field
[0001] The utility model relates to the technical field of smart construction site equipment, and in particular to a movable dust monitoring device for smart construction sites. Background Art
[0002] A smart construction site refers to the use of information technology to accurately design and simulate construction projects through a three-dimensional design platform. Focusing on construction process management, it establishes an information ecosystem for construction projects that is interconnected, collaborative, intelligently produced, and scientifically managed. This data is then combined with engineering information collected by the Internet of Things in a virtual reality environment for data mining and analysis. This provides process trend forecasts and expert plans, and enables visual and intelligent management of engineering construction, thereby improving the level of information technology in engineering management and gradually realizing green and ecological construction.
[0003] like Figure 4 As shown in the figure, it is the previous generation of mobile dust monitoring device for smart construction sites. Its main function is to collect environmental data such as PM2.5, PM10, temperature and humidity in the construction area of the construction site in real time, so as to facilitate construction personnel to understand the environmental conditions of the construction area and promptly carry out spraying dust suppression treatment in the construction area. However, the previous generation of dust monitoring devices has the following shortcomings during actual use: In order to facilitate mobile use in the construction area, four self-locking universal wheels are added to the counterweight base. Although the self-locking universal wheels can be locked, when the dust monitoring device is subjected to external force, it is prone to lateral movement, shaking or even tipping over, which reduces the stability of the fixed-point placement of the dust monitoring device.
[0004] In view of this, it is particularly important to design and manufacture a movable dust monitoring device that has good stability when placed at a fixed point after movement and adjustment, and to apply it in the actual use of smart construction sites. Utility Model Content
[0005] The purpose of this utility model is to solve the problem that the previous generation of dust monitoring devices is difficult to move within the construction area, but the stability of the fixed-point placement is poor, and it is easy to move sideways, shake or even fall under the action of external forces. A movable smart dust monitoring device for construction sites is proposed.
[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0007] A movable intelligent dust monitoring device for construction sites includes a counterweight base, self-locking universal wheels installed at the four corners of the lower end of the counterweight base, a column fixed at the middle of the upper end of the counterweight base, a display screen fixed at the top of the front end of the column, and an environmental data collector installed at the upper end of the column. The lower end of the counterweight base is equipped with a fixing base covering the left end, lower end and right end of the counterweight base, and a sliding lock mechanism is provided between the fixing base and the counterweight base for fixing the counterweight base to the inner side of the fixing base without tools.
[0008] As a further description of the above technical solution:
[0009] The sliding lock mechanism includes a U-shaped buckle fixed in the middle of the upper end of the fixed seat, two upper buckle strips fixed in parallel to the lower end of the counterweight base and located above the two vertical ends of the U-shaped buckle, a vertical groove opened between the upper end of the counterweight base and the two upper buckle strips, a limiting lock block movably installed on the inner side of the vertical groove and passing downward through the U-shaped buckle, and a limiting lock groove opened at the upper end of the U-shaped buckle and locked with the limiting lock block.
[0010] As a further description of the above technical solution:
[0011] The left and right ends of the fixing seat are both fixedly connected with guide blocks that penetrate the counterweight base inwardly and laterally. The left and right ends of the counterweight base are both provided with guide grooves for accommodating the guide blocks.
[0012] As a further description of the above technical solution:
[0013] The upper end of the limiting lock block is fixedly connected with a handle, and a limiting portion is provided between the counterweight base and the upper end of the limiting lock block to prevent the limiting lock block from accidentally sliding up in the vertical slot.
[0014] As a further description of the above technical solution:
[0015] The limiting part includes a rotary disk rotatably mounted on the upper end of the counterweight base and close to the limiting lock block, an outer convex end integrally fixed to the outside of the rotary disk and capable of abutting against the upper end of the limiting lock block, and a knob fixed to the upper end of the rotary disk.
[0016] As a further description of the above technical solution:
[0017] The upper end of the fixing seat is provided with a plurality of vertically penetrating mounting holes.
[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0019] 1. In the present invention, the original dust monitoring device is scientifically and rationally improved. A fixing seat, a U-shaped buckle, a limit lock groove, an upper buckle strip, a vertical slot and a limit lock block are arranged under the counterweight base. The fixing seat can be pre-placed or fixed on the placement area. The fixing base can slide horizontally to the inside of the fixing seat through the self-locking universal wheel. In the process of the fixing base sliding into the fixing seat, the upper buckle strip on the counterweight base can slide into the top of the U-shaped buckle. The contact and extrusion between the U-shaped buckle and the limit lock block Under the action of force, the limit lock block can move upward in the vertical groove in advance. When the limit lock block is adjusted to be at the same vertical center line as the limit lock groove, the limit lock block can slide down and be locked in the limit lock groove under the action of gravity, and the counterweight base can be fixed in the fixed seat. This structure can perform comprehensive limiting processing on the dust monitoring device after movement and adjustment, avoiding the occurrence of problems such as lateral movement, shaking or even tipping of the dust monitoring device after movement and adjustment, thereby improving the stability of the fixed-point placement of the dust monitoring device.
[0020] 2. In the present invention, a turntable, a convex end and a knob are provided between the original counterweight base and the limit lock block. By holding and turning the knob on the turntable, the convex end can be rotated and adjusted on the turntable. When the convex end is adjusted to above the limit lock block, the limit lock block can be restricted from moving vertically upward in the limit lock groove and the vertical groove. This structure can vertically limit the limit lock block that is slid into the limit lock groove, thereby avoiding the problem of the limit lock block sliding and unlocking under force, thereby further improving the stability of the fixed-point placement of the dust monitoring device.

[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0028] See also Figure 1-4 The utility model provides a technical solution: a movable intelligent dust monitoring device for construction sites, comprising a counterweight base 1, self-locking universal wheels 101 installed at the four corners of the lower end of the counterweight base 1, a column 2 fixed to the middle part of the upper end of the counterweight base 1, a display screen 3 fixed to the top of the front end of the column 2 and an environmental data collector 4 installed at the upper end of the column 2. A fixing base 5 covering the left, lower and right ends of the counterweight base 1 is installed at the lower end of the counterweight base 1, and a sliding lock mechanism is provided between the fixing base 5 and the counterweight base 1 for fixing the counterweight base 1 to the inner side of the fixing base 5 without tools.
[0029] Specifically, such as Figure 1-3 As shown, the sliding locking mechanism includes a U-shaped buckle 502 fixed to the middle part of the upper end of the fixed seat 5, two upper buckle strips 102 fixed in parallel to the lower end of the counterweight base 1 and located above the two vertical ends of the U-shaped buckle 502, a vertical groove 103 opened between the upper end of the counterweight base 1 and the two upper buckle strips 102, a limit lock block 6 movably installed on the inner side of the vertical groove 103 and passing downward through the U-shaped buckle 502, and a limit lock groove 503 opened at the upper end of the U-shaped buckle 502 and locked with the limit lock block 6. After the limit lock block 6 slides downward into the limit lock groove 503 on the U-shaped buckle 502, it can limit the horizontal movement of the two upper buckle strips 102 on the U-shaped buckle 502, thereby realizing the tool-free limit locking of the counterweight base 1 on the fixed seat 5.
[0030] Specifically, such as Figure 1-3As shown, the left and right ends of the fixed seat 5 are fixedly connected with guide blocks 504 that pass through the counterweight base 1 inward and horizontally. The left and right ends of the counterweight base 1 are provided with guide grooves 104 for accommodating the guide blocks 504. The setting of the guide blocks 504 and the guide grooves 104, on the one hand, facilitates the guidance of the counterweight base 1 to slide into the fixed seat 5, so that the two upper buckle strips 102 on the counterweight base 1 can be quickly positioned and slid onto the U-shaped buckle 502 of the fixed seat 5. On the other hand, it can limit the vertical displacement and shaking of the counterweight base 1 on the fixed seat 5, thereby improving the stability of the counterweight base 1 fixed on the fixed seat 5.
[0031] Specifically, such as Figure 1-3 As shown, the upper end of the limit lock block 6 is fixedly connected to a handle 601, which is convenient for the operator to hold the limit lock block 6 and perform lifting and lowering adjustment operations. A limit portion is provided between the counterweight base 1 and the upper end of the limit lock block 6 to prevent the limit lock block 6 from accidentally sliding up in the vertical slot 103. The limit portion includes a turntable 7 rotatably mounted on the upper end of the counterweight base 1 and close to the limit lock block 6, an outer convex end 701 integrally fixed to the outside of the turntable 7 and abutting against the upper end of the limit lock block 6, and a knob 702 fixed on the upper end of the turntable 7, which is convenient for the operator to rotate and adjust the turntable 7. When the outer convex end 701 of the turntable 7 is adjusted to abut against the upper end of the limit lock block 6, the limit lock block 6 can be stably limited between the vertical slot 103 and the limit lock slot 503.
[0032] Specifically, such as Figure 1-3 As shown, a plurality of vertically through-distributed mounting holes 501 are provided at the upper end of the fixing base 5 to facilitate the fixing of the fixing base 5 to the ground by fasteners.
[0033] Working principle: When in use, the fixing base 5 can be placed on the designated placement ground according to the actual usage situation, or the fixing base 5 can be fixed on the placement ground with fasteners. When the dust monitoring device needs to be placed at a fixed point, the two upper buckle strips 102 at the lower end of the counterweight base 1 are respectively slid toward and horizontally backward into the U-shaped buckle 502 of the fixing base 5. In this process, the limiting lock block 6 between the counterweight base 1 and the two upper buckle strips 102 can be pre-slid upward and hidden in the vertical groove 103 under the contact and extrusion force of the U-shaped buckle 502. When the counterweight base 1 is completely slid into the fixing base 5, the U-shaped buckle 50 2 can move to the bottom of the limit lock block 6. Under the action of gravity, the limit lock block 6 can slide downward in the vertical groove 103 into the limit lock groove 503, thereby locking the U-shaped buckle 502 between the two upper buckle bars 102, completing the self-locking operation after the counterweight base 1 slides into the fixed seat 5. In order to further improve the stability of the counterweight base 1 fixed in the fixed seat 5, the operator can hold and turn the knob 702, and rotate the outer protruding end 701 on the turntable 7 until it is in contact with the upper end of the limit lock block 6, so as to limit the vertical movement of the limit lock block 6 in the vertical groove 103 and the limit lock groove 503.
[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
