Description

Technical Field

[0001] The present invention relates to the technical field of construction site alarms, and in particular to intelligent construction alarm equipment for a construction site. Background Art

[0002] Intelligent construction alarm equipment at construction sites refers to an equipment system designed using intelligent technology at construction sites. It is used to monitor the construction environment, equipment and personnel status in real time, and automatically issues warnings or alarm signals when abnormal conditions or potential dangers are detected. It aims to improve the safety protection level of the construction site and prevent or reduce the occurrence of safety accidents.

[0003] After searching, the Chinese patent with publication number CN116721514A discloses an intelligent construction alarm device for a construction site, including an alarm box, a fixing mechanism for fixing the alarm box to a foundation pit is arranged at the bottom of the alarm box, and an LED alarm light is fixedly installed on the top of the alarm box; by setting a monitoring mechanism and a controller, the controller uses the measured distance of an infrared rangefinder to calculate the warning level representing the operating status of the LED alarm light and the loudspeaker, so as to facilitate the determination of the operating status of the LED alarm light and the loudspeaker according to the actual situation, play an early warning role for personnel and construction machinery, improve the warning effect of the alarm device, and avoid affecting the surrounding environment and personnel; by setting a warning mechanism, the warning mechanism is used to realize the linkage of multiple alarm devices, so that multiple alarm devices are connected by a warning line to form a warning area, which further improves the warning effect of the alarm device. However, in the actual use of this technical solution, there are still the following deficiencies:

[0004] In the intelligent construction process of using infrared rangefinders for on-site measurement and early warning, since construction sites are often accompanied by a large amount of dust, these dust particles are suspended in the air and easily attached to various equipment, including infrared rangefinders. As a precision instrument that relies on precise light beam transmission and reception to achieve distance measurement, the working performance of infrared rangefinders is highly dependent on the purity and stability of the light beam. However, with the extension of usage time, especially in construction environments with high dust concentrations, a layer of dust film will inevitably accumulate on the lens, transmitting window and receiving components of the infrared rangefinder. The long-term accumulation of dust not only affects the instantaneous measurement accuracy of the infrared rangefinder, and then affects the response speed and accuracy of the alarm system based on these measurement data, but may also bring potential risks to construction safety due to false alarms or missed alarms.

[0063] like Figures 1 to 6 As shown, an intelligent construction alarm device for a construction site includes a chassis 1; a support rod 2, which is fixedly installed on the top surface of the chassis 1; an alarm box 3, which is fixedly installed on the support rod 2; a plurality of infrared ranging plates 4, which are arranged on the side of the alarm box 3 in a linear array; a wind cup 5, which is arranged at the upper position of the support rod 2; a blowing mechanism, which is arranged at the top of the support rod 2; a plurality of groups of brushing mechanisms, which are respectively arranged on the side of the alarm box 3 at the positions of the plurality of infrared ranging plates 4; a water collecting bucket 8, which is fixedly installed on the top surface of the alarm box 3 by a fixing rod, and a water collecting cover 10 is fixedly installed at the side position of the top surface of the water collecting bucket 8; a water collecting mechanism, which is arranged on the water collecting bucket 8;

[0064] When in use, the chassis 1 and the support rod 2 can be installed at the foundation pit position or the position that needs to be blocked at the construction site, and the alarm box 3 can be opened. The infrared ranging board 4 can sense the person approaching the foundation pit or the blocked position. Once the person crosses the infrared ray, the alarm box 3 can immediately issue an alarm to warn the person to avoid danger. During the use of the infrared ranging board 4, when the weather is clear and windy, the wind can drive the wind cup 5, and the wind conditions at the construction site can be monitored through the wind cup 5. During the rotation of the wind cup 5, the floating and sinking on the surface of the infrared ranging board 4 can be cleaned by the blowing mechanism to reduce the adhesion of dust. In rainy weather, rainwater can be collected into the water collecting bucket 8 through the water collecting cover 10, and when a certain amount is collected, the infrared ranging board 4 can be cleaned by the cooperation of the water collecting mechanism and the brushing mechanism, ensuring that the infrared ranging board 4 can be kept clean to ensure the accuracy of its ranging. The working principle and connection method of the alarm box 3 and the infrared ranging board 4 are existing mature technologies and will not be elaborated here.

[0065] like Figure 1 , Figure 2 , Figure 3As shown, the blowing mechanism includes: a support tube 61, which is fixedly mounted on the top of the support rod 2, and the wind cup 5 is fixedly mounted on the top surface of the support tube 61; a transmission shaft 62, which is rotatably mounted on the inner bottom wall of the support tube 61, and the top of the transmission shaft 62 passes through the top surface of the support tube 61 and is fixedly connected to the driving shaft of the wind cup 5; a plurality of blades 63, which are distributed in a circular array and fixedly mounted on the outer wall of the transmission shaft 62; an air inlet pipe 64, which is arranged through the outer wall of the support tube 61; an air outlet pipe 65, which is arranged through the bottom surface of the support tube 61, and the end of the air outlet pipe 65 away from the support tube 61 extends to the side of the alarm box 3, and the inner walls of the air inlet pipe 64 and the air outlet pipe 65 are installed with one-way valves with opposite flow directions; a plurality of conduits 66, which are respectively arranged at the outer wall of the air outlet pipe 65 and the corresponding positions of the plurality of infrared ranging plates 4; a plurality of blowing heads 67, which are respectively fixedly mounted on the side of the alarm box 3 and located at the side positions of the plurality of infrared ranging plates 4, and the conduits 66 are connected with the blowing heads 67;

[0066] When the wind cup 5 is driven by wind, the driving shaft can drive the transmission shaft 62 to rotate synchronously. When the transmission shaft 62 rotates, since the support tube 61 is externally connected to the air inlet pipe 64 and the air outlet pipe 65, and the air inlet pipe 64 and the air outlet pipe 65 are installed with one-way valves with opposite flow directions, when the transmission shaft 62 drives the paddle 63 to rotate in the support tube 61, the external air can flow into the support tube 61 through the air inlet pipe 64, and the gas in the support tube 61 can be discharged through the air outlet pipe 65, thereby forming a circulation, and the gas in the air outlet pipe 65 can be sprayed to the side of the infrared ranging plate 4 through the duct 66 and the blower head 67, so that the floating and sinking on the infrared ranging plate 4 can be cleaned.

[0067] like Figure 4 , Figure 5 As shown, the brushing mechanism includes: a reciprocating screw 71, which is rotatably mounted on the side of the alarm box 3 and located above the infrared ranging plate 4; a guide rod 72, which is fixedly mounted on the side of the alarm box 3 and located below the infrared ranging plate 4; a connecting block 73, which is slidably mounted on the outer wall of the guide rod 72; a support block 74, which is threadedly mounted on the outer wall of the reciprocating screw 71; a rotating shaft 75, which is rotatably mounted between the opposite sides of the connecting block 73 and the support block 74, and the top of the rotating shaft 75 passes through the support block 74 and is fixedly mounted with a driven wheel 78 that fits the side of the alarm box 3; a cleaning roller 76, which is fixedly mounted on the outer wall of the rotating shaft 75; a scraper 77, which is fixedly mounted on the side of the support block 74 through a bracket, and the scraper 77 is inclined. The scraper 77 is made of rubber material;

[0068] When it rains, part of the rainwater can be collected in the water collection bucket 8, and a small part of the rainwater can adhere to the side of the infrared ranging plate 4. The rainwater in the water collection bucket 8 can drive the reciprocating screw 71 to rotate. Since the support block 74 and the connecting block 73 are connected by the rotating shaft 75, and the support block 74 and the connecting block 73 are respectively connected to the reciprocating screw 71 and the guide rod 72, the reciprocating screw 71 can drive the rotating shaft 75 and the cleaning roller 76 when it rotates. The rotating shaft 75 moves along the During the sliding process of the guide rod 72, the driven wheel 78 can be driven to rotate along the side of the alarm box 3, so that the cleaning roller 76 can be driven to rotate in an orderly manner, so that the cleaning roller 76 can clean the side of the infrared ranging plate 4. At the same time, during the cleaning process of the cleaning roller 76, the scraper 77 can scrape off the water on the infrared ranging plate 4, so that the cleaning is more thorough. After the cleaning is completed, the cleaning roller 76 and the scraper 77 can be reset to the side position of the infrared ranging plate 4, so that the infrared ranging plate 4 can be used normally.

[0069] like Figure 4 , Figure 6 As shown, the water collection mechanism includes: a plurality of fixed shells 91, which are respectively fixedly installed on the side of the alarm box 3 and at the corresponding positions of the plurality of reciprocating screws 71, and a drainage pipe is provided through the outer wall of the fixed shell 91 located at the bottom of the plurality of fixed shells 91; a plurality of impellers 92, which are respectively rotatably installed on the inner side walls of the plurality of fixed shells 91, and the end of the reciprocating screw 71 is fixedly connected to the impeller 92; a plurality of connecting pipes 93, which are respectively provided between the plurality of fixed shells 91; a downpipe 94, which is provided on the bottom surface of the water collection bucket 8, and the bottom end of the downpipe 94 is connected to the fixed shell 91 at the top; a drainage mechanism, which is provided on the inner wall of the downpipe 94;

[0070] Rainwater is collected into the water collecting barrel 8 through the water collecting cover 10, so that the water collecting range of the water collecting barrel 8 is larger, and the rainwater in the water collecting barrel 8 can be discharged in an orderly manner through the drainage mechanism, so that the rainwater enters the fixed shell 91 through the downpipe 94, and passes through several fixed shells 91 in sequence through the connecting pipe 93. When the rainwater passes through the fixed shell 91, since the pipeline is arranged at the side position of the fixed shell 91, the rainwater can drive the impeller 92, so that the rotation of the impeller 92 drives the reciprocating screw 71 to rotate, thereby realizing the driving of the reciprocating screw 71. Through the use of the drainage mechanism, the single drainage volume can drive the reciprocating screw 71 to a round trip stroke of the cleaning roller 76 for cleaning, ensuring that the cleaning roller 76 can be reset after use. The principle of single drainage volume control here is an existing mature technology and will not be elaborated on here.

[0071] like Figure 6As shown, the drainage mechanism includes: a support shaft 95, which is rotatably mounted on the inner wall of the downpipe 94, and one end of the support shaft 95 passes through the outer wall of the downpipe 94; a baffle 96, which is fixedly sleeved on the outer wall of the support shaft 95, and the outer wall of the baffle 96 is in contact with the inner wall of the downpipe 94; a torsion spring 97, which is sleeved on one end of the support shaft 95 located outside the downpipe 94, and the two ends of the torsion spring 97 are fixedly connected to the support shaft 95 and the downpipe 94 respectively;

[0072] When the rainwater collects in the water collection barrel 8 to a certain amount, the baffle 96 can be pressed under the action of gravity, so that the baffle 96 and the support shaft 95 rotate. At this time, the baffle 96 can be separated from the inner wall of the sewer pipe 94, and the rainwater can pass through the baffle 96 into the fixed shell 91. After drainage, the support shaft 95 and the baffle 96 can be reversed to a horizontal position under the action of the torsion spring 97 to drain water again. The support shaft 95 is set at an eccentric position of the sewer pipe 94 to ensure that the rainwater can press the baffle 96.
