Technical Field

[0001] This invention relates to the field of engineering monitoring technology, specifically to a site monitoring device for construction project management. Background Technology

[0002] The construction project management site monitoring device is an intelligent device that integrates multiple functions such as dust monitoring, automatic dust reduction, impurity cleaning, and water resource recycling. It is mainly used for environmental monitoring and supporting water system management at construction sites to ensure that the construction environment meets standards and water resources are used efficiently.

[0003] The patent with publication number CN215639576U includes a base with a water tank inside. A water pump is located inside the water tank. An electric telescopic rod is installed in the middle of the base, and a tank is located on the upper part of the electric telescopic rod. Multiple atomizing nozzles are arranged in a ring at equal intervals above the tank. An electric fan is located below the atomizing nozzles. A first ring is located on the outer side of the tank, and a second ring is located below the first ring. A connecting rod is connected below the electric fan. A water pipe is located on the right side of the tank. An insertion rod is located at the front of the base, and a dust sensor and a temperature sensor are installed on the upper part of the insertion rod. This patent can automatically spray to cool down the tank on hot days.

[0004] The aforementioned patent can automatically spray to cool down in hot weather, but there are still problems. It is difficult to ensure that there is enough water in the water storage box when the water is sprayed, and it is also difficult to ensure that the ground at the bottom will become muddy when the water is sprayed, causing the ground to become soft and rotten, which will not be able to guarantee the normal operation of the machine. Furthermore, it is impossible to recycle the wasted water resources, resulting in a great waste. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a site monitoring device for construction project management, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a construction project management on-site monitoring device, comprising a chassis, an auxiliary device for detecting the liquid content inside the chassis, the auxiliary device further comprising; The detection rod is located on the top of the housing, and a water spray pipe is provided on the circumference of the detection rod. A telescopic motor is provided at the bottom of the housing. The detection rod is used to detect dust at the construction site. A pressure plate is slidably installed on the inner wall of the chassis. A limit rod is slidably installed on the bottom of the pressure plate. An arc-shaped plate is slidably installed on the bottom of the chassis. The limit rod is used to quickly pick up and put down the pressure plate. A sealed box is fixedly installed on the front of the machine housing. A pressure block is fixedly installed on the side of the pressure plate near the sealed box. The free end of an elastic telescopic push plate is fixedly installed on the bottom of the pressure block. The fixed end of the elastic telescopic push plate is fixedly installed on the bottom of the sealed box. The pressure block is used to control the moving speed of the telescopic motor. When the fixed block moves together, it will drive the limit rod to move. When the limit rod moves, it will drive the pressure plate to move. When the pressure plate moves, the water sprayed from the water pipe will be subjected to greater pressure, thereby making the water sprayed from the water pipe cover a wider range.

[0007] According to the above technical solution, the auxiliary device also includes a fixed block, a square tube, and a movable plate. The fixed block is fixedly installed at the output end of the telescopic motor. The square tube is fixedly installed on the side of the sealing box near the telescopic motor. The movable plate is slidably installed inside the square tube. When the movable plate moves, it will contact the arc plate. At the same time, when the pressure plate moves, it will drive the limit rod to move downward. When the pressure plate moves downward to the bottom, the limit rod will contact the arc plate.

[0008] According to the above technical solution, the movable plate is in contact with the arc-shaped plate, the fixed block is in contact with the limiting rod, and the limiting rod is in contact with the arc-shaped plate; The chassis is equipped with a cleaning device inside to remove wastewater containing impurities from the bottom and a recycling device on the back of the chassis to collect and reuse liquid leaking from the top of the chassis. When the limiting rod releases contact with the fixing block, the limiting of the pressure plate is released. When the limiting of the pressure plate is released, the operator can remove the pressure plate and fill the inside of the chassis with water.

[0009] According to the above technical solution, the cleaning device includes a vertical toothed plate, a gear, a rack, a push rod, a baffle, and an elastic telescopic push block. The vertical toothed plate is fixedly installed at the bottom of the pressure plate. The gear is rotatably installed on the inner wall of the housing. The rack is slidably installed at the bottom of the inner wall of the housing. The baffle is slidably installed at the bottom of the inner wall of the housing. The push rod is fixedly installed at the top of the rack. The elastic telescopic push block is fixedly installed on the side of the push rod near the baffle. When the push rod moves, it will drive the elastic telescopic push block to move. When the elastic telescopic push block moves, it will first contact the baffle. When the baffle contacts the elastic telescopic push block, it will cause the elastic telescopic push block to retract.

[0010] According to the above technical solution, the cleaning device further includes a water storage box, a long rod, a short rod, a contact block, and a tray. The water storage box is fixedly installed on the back of the chassis. The long rod is slidably installed on the right side of the water storage box. The short rod is fixedly installed on the top of the long rod. The contact block is fixedly installed inside the water storage box. The tray is slidably installed on the inner wall of the water storage box. The push rod allows the remaining impurities inside the chassis to flow out through the through hole, preventing the impurities inside the chassis from obstructing the liquid sprayed from the water spray pipe next time. In addition, the elastic telescopic push block can prevent the baffle from being pushed open when it is not blocked.

[0011] According to the above technical solution, the short bar contacts the contact block, and the long bar contacts the rack. When the short bar contacts the contact block, it will cause the water storage box to vibrate. When the water storage box vibrates, the water and impurities inside the water storage box can move and be screened quickly.

[0012] According to the above technical solution, the recycling device includes an elastic telescopic column, an irregular rod, an L-plate, a screen frame, a water pipe, a water-blocking plate, and a limiting plate. The fixed end of the elastic telescopic column is fixedly installed on the inner wall of the water storage box. One end of the irregular rod is fixedly installed on the free end of the elastic telescopic column. The L-plate is fixedly installed on the other end of the irregular rod and is slidably connected to the water storage box. The screen frame is slidably installed inside the water storage box. The water pipe is fixedly installed on the back of the casing. The water-blocking plate is slidably installed at the bottom of the water pipe. The limiting plate is fixedly installed at the bottom of the screen frame. A flexible plate is provided on the top of the screen frame. When the L-plate moves downward, it releases the limiting plate at the bottom of the screen frame. When the limiting plate at the bottom of the screen frame is released, the screen frame moves downward. When the screen frame moves downward, it blocks the front of the water storage box.

[0013] According to the above technical solution, the water-blocking plate is in contact with the limiting plate, the water pipe is in contact with the top flexible plate of the screen frame, and the elastic telescopic column is in contact with the support plate. When the screen frame moves, it will drive the flexible plate at the bottom of the water-blocking plate to move. When the flexible plate at the bottom of the water-blocking plate moves, it will drive the water-blocking plate to move. When the water-blocking plate moves, it will seal the bottom of the water pipe.

[0014] This invention provides a site monitoring device for construction project management. It has the following beneficial effects: (1) In this invention, the pressure inside the spray pipe increases when the pressure plate moves, so that the sprayed water range is wider and can fully cover the dusty area of ​​the construction site, thereby improving the overall dust reduction efficiency. Through a series of linkage structures driven by the telescopic motor, the limit on the pressure plate is automatically released without the need for manual unlocking. At the same time, the elastic telescopic push plate provides upward assistance, reducing the force required for workers to remove the pressure plate, saving physical strength, and speeding up the water injection preparation speed. When the detection rod detects excessive dust, the spray pipe and the telescopic motor can be started at the same time, without the need for manual operation of the two components, reducing manual intervention steps and improving the automation level of the device. The movement of the pressure plate is driven by the mechanical structure, which is more stable than manual adjustment of water pressure and can continuously provide sufficient pressure to the spray pipe to ensure the consistency of dust reduction effect.

[0015] (2) In this invention, the linkage structure of the pressure plate movement will automatically push open the baffle, allowing impurities in the chassis to be discharged through the bottom through hole, avoiding impurities from clogging the water spray pipe and ensuring the stability of the subsequent water spray dust reduction effect; at the same time, the buffer effect of the elastic telescopic push block can prevent the baffle from being pushed open accidentally, avoiding the waste of water resources in the chassis; the linkage structure driven by the movement of the rack and pinion causes the water storage box to vibrate, which can quickly separate water and impurities in the box and improve the cleanliness of the stored water; at the same time, the vibration is transmitted to the tray, which can remove impurities between the tray and the water storage box, preventing the tray from being blocked when moving, and ensuring the normal operation of the water storage box and related components.

[0016] (3) When the top of the tray is full of water, the screen frame moves downward through the linkage structure to block the front of the water storage box, thereby expanding the effective water storage space of the water storage box and storing more water. This avoids liquid overflow and waste. When the screen frame moves, it drives the water blocking plate to seal the bottom of the water pipe, cutting off the water supply channel to the water storage box and preventing water that may carry impurities from entering. This maintains the cleanliness of the water that has been screened inside the water storage box and prevents secondary turbidity. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-7 One embodiment of the present invention is: a construction project management on-site monitoring device, including a chassis 1, an auxiliary device for detecting the liquid content inside the chassis 1, the auxiliary device further comprising; The detection rod 2 is set on the top of the housing 1. A water spray pipe 3 is set on the circumference of the detection rod 2. A telescopic motor 4 is set on the bottom of the housing 1. The detection rod 2 is used to detect dust on the construction site. Pressure plate 403 is slidably installed on the inner wall of the chassis 1. Limiting rod 410 is slidably installed on the bottom of pressure plate 403. Arc plate 409 is slidably installed on the bottom of chassis 1. Limiting rod 410 is used to quickly pick up and put down pressure plate 403. A sealing box 405 is fixedly installed on the front of the casing 1. A pressure block 404 is fixedly installed on the side of the pressure plate 403 near the sealing box 405. The free end of the elastic telescopic push plate 406 is fixedly installed on the bottom of the pressure block 404. The fixed end of the elastic telescopic push plate 406 is fixedly installed on the bottom of the sealing box 405. The pressure block 404 is used to control the moving speed of the telescopic motor 4. The elastic telescopic push plate 406 provides upward assistance, reducing the force required for workers to remove the pressure plate 403, saving physical strength, and speeding up the water injection preparation. When the detection rod 2 detects excessive dust, it can simultaneously start the water spray pipe 3 and the telescopic motor 4, eliminating the need for manual operation of the two components, reducing manual intervention steps, and improving the automation level of the device. The movement of the pressure plate 403 is driven by a mechanical structure, which is more stable than manual water pressure adjustment and can continuously provide sufficient pressure to the water spray pipe 3 to ensure consistent dust suppression effect.

[0021] The auxiliary device also includes a fixed block 401, a square tube 407, and a movable plate 408. The fixed block 401 is fixedly installed at the output end of the telescopic motor 4. The square tube 407 is fixedly installed on the side of the sealed box 405 near the telescopic motor 4. The movable plate 408 is slidably installed inside the square tube 407. When the movable plate 408 moves, it will contact the arc plate 409. At the same time, when the pressure plate 403 moves, it will drive the limit rod 410 to move downward. When the pressure plate 403 moves downward to the bottom, the limit rod 410 will contact the arc plate 409.

[0022] The movable plate 408 contacts the arc plate 409, the fixed block 401 contacts the limiting rod 410, and the limiting rod 410 contacts the arc plate 409. When the contact between the limiting rod 410 and the fixed block 401 is released, the limiting of the pressure plate 403 will be released. When the limiting of the pressure plate 403 is released, the operator can remove the pressure plate 403 and fill the inside of the casing 1 with water.

[0023] In this embodiment, during operation: the staff moves the chassis 1 to the construction site, and then activates the detection rod 2 inside the chassis 1. When the detection rod 2 is activated, it will detect dust on the construction site. When the dust is too large, it will activate the water spray pipe 3 to spray water around the construction site. At the same time, the telescopic motor 4 is activated. When the telescopic motor 4 is activated, it will drive the fixed block 401 to move. When the fixed block 401 moves together, it will drive the limit rod 410 to move. When the limit rod 410 moves, it will drive the pressure plate 403 to move. When the pressure plate 403 moves, it will make the water sprayed from the water spray pipe 3 more pressured, thus making the water sprayed from the water spray pipe 3 cover a wider range. When the pressure plate 403 moves downward, it will drive the pressure block 404 inside the sealing box 405 to move. When the pressure block 404 moves a certain distance, it will compress the air inside the sealing box 405. When the air inside the sealing box 405 is compressed, it will push the moving plate 408 inside the square tube 407. When the moving plate 408 is pushed, it will move forward. When the moving plate 408 moves, it will contact the arc plate 409. At the same time, when the pressure plate 403 moves, it will drive the limiting rod 410 to move downward. When the pressure plate 403 moves downward to the bottom, it will cause the limiting rod 410 to contact the arc plate 409. After the arc plate 409 contacts the limiting rod 410, and after the moving plate 408 contacts the arc plate 409, it will cause the arc plate 409 to move. When the arc plate 409 moves, it will drive the limiting rod 410 to move. When the limiting rod 410 moves, it will release its contact with the fixing block 401. When the contact between the limiting rod 410 and the fixing block 401 is released, the limiting of the pressure plate 403 will be released. When the limiting of the pressure plate 403 is released, the operator can take out the pressure plate 403 and fill the inside of the casing 1 with water. At the same time, because the pressure block 404 is in contact with the sealing box 405 through the elastic telescopic push plate 406, when the operator needs to take out the pressure plate 403, the elastic telescopic push plate 406 will generate an upward force on the pressure plate 403, thereby reducing the force required for the operator to take out the pressure plate 403.

[0024] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the interior of the chassis 1 is provided with a cleaning device for cleaning wastewater containing impurities at the bottom, and the back of the chassis 1 is provided with a recycling device for collecting and reusing liquid leaked from the top of the chassis 1. The cleaning device includes a vertical toothed plate 501, a gear 502, a rack 503, a push rod 504, a baffle 505, and an elastic telescopic push block 506. The vertical toothed plate 501 is fixedly installed at the bottom of the pressure plate 403, the gear 502 is rotatably installed on the inner wall of the chassis 1, and the rack 503 is slidably installed on the inner wall of the chassis 1. At the bottom of the inner wall of the chassis 1, a baffle 505 is slidably installed. A push rod 504 is fixedly installed on the top of the rack 503. An elastic telescopic push block 506 is fixedly installed on the side of the push rod 504 near the baffle 505. The linkage structure driven by the movement of the rack 503 causes the water storage box 507 to vibrate, which can quickly separate water and impurities in the box and improve the cleanliness of the stored water. At the same time, the vibration is transmitted to the tray 511, which can remove impurities between the tray 511 and the water storage box 507, prevent the tray 511 from being blocked when it moves, and ensure the normal operation of the relevant components of the water storage box 507.

[0025] The cleaning device also includes a water storage box 507, a long bar 508, a short bar 509, a contact block 510, and a tray 511. The water storage box 507 is fixedly installed on the back of the chassis 1. The long bar 508 is slidably installed on the right side of the water storage box 507. The short bar 509 is fixedly installed on the top of the long bar 508. The contact block 510 is fixedly installed inside the water storage box 507. The tray 511 is slidably installed on the inner wall of the water storage box 507. The push rod 504 allows the remaining impurities inside the chassis 1 to flow out through the through hole, preventing the impurities inside the chassis 1 from obstructing the liquid sprayed from the water spray pipe 3 next time. In addition, the elastic telescopic push block 506 can prevent the baffle 505 from being pushed open when it is not blocked.

[0026] The short bar 509 contacts the contact block 510, and the long bar 508 contacts the rack 503. When the short bar 509 contacts the contact block 510, it will cause the water storage box 507 to vibrate. When the water storage box 507 vibrates, the water and impurities inside the water storage box 507 can move and be screened quickly.

[0027] The recycling device includes an elastic telescopic column 601, an irregular rod 602, an L-plate 603, a screen frame 604, a water pipe 605, a water-blocking plate 606, and a limiting plate 607. The fixed end of the elastic telescopic column 601 is fixedly installed on the inner wall of the water storage box 507. One end of the irregular rod 602 is fixedly installed on the free end of the elastic telescopic column 601. The L-plate 603 is fixedly installed on the other end of the irregular rod 602 and is slidably connected to the water storage box 507. The screen frame 604 is slidably installed inside the water storage box 507. The water pipe 605 is fixedly installed on the back of the casing 1. The water blocking plate 606 is slidably installed on the bottom of the water pipe 605. The limiting plate 607 is fixedly installed on the bottom of the screen frame 604. The top of the screen frame 604 is provided with a flexible plate. When the screen frame 604 moves, it drives the water blocking plate 606 to close the bottom of the water pipe 605, cutting off the water supply channel to the water storage box 507 and preventing water that may carry impurities from entering. This maintains the cleanliness of the water that has been screened inside the water storage box 507 and prevents secondary turbidity.

[0028] The water-blocking plate 606 contacts the limiting plate 607, the water pipe 605 contacts the top flexible plate of the screen frame 604, and the elastic telescopic column 601 contacts the support plate 511. When the screen frame 604 moves, it will drive the flexible plate at the bottom of the water-blocking plate 606 to move. When the flexible plate at the bottom of the water-blocking plate 606 moves, it will drive the water-blocking plate 606 to move. When the water-blocking plate 606 moves, it will seal the bottom of the water pipe 605.

[0029] In this embodiment, when the pressure plate 403 moves, it drives the vertical toothed plate 501 to move. When the vertical toothed plate 501 moves, it meshes with the gear 502 inside the chassis 1, causing the gear 502 to rotate. When the gear 502 rotates, it drives the rack 503 to move. When the rack 503 moves, it drives the push rod 504 to move. When the push rod 504 moves, it drives the elastic telescopic push block 506 to move. When the elastic telescopic push block 506 moves, it first contacts the baffle 505. When the baffle 505 contacts the elastic telescopic push block 506, it causes the elastic telescopic push block 506 to retract. When the elastic telescopic push block 506 retracts to a certain extent, it will push the baffle 505 to move. When the baffle 505 moves, the through hole at the bottom of the chassis 1 will be exposed. The push rod 504 will let the remaining impurities inside the chassis 1 flow out through the through hole, so as to prevent the impurities inside the chassis 1 from obstructing the liquid sprayed from the water spray pipe 3 next time. In addition, the elastic telescopic push block 506 can prevent the baffle 505 from being pushed open without being blocked, thus avoiding the waste of water resources inside the chassis 1. At the same time, when the rack 503 moves, it will contact the long rod 508. When the rack 503 contacts the long rod 508, it will cause the long rod 508 to move. When the long rod 508 moves, it will drive the short rod 509 to move. When the short bar 509 moves, it will contact the contact block 510. When the short bar 509 contacts the contact block 510, it will cause the water storage box 507 to vibrate. When the water storage box 507 vibrates, the water and impurities inside the water storage box 507 can move and be screened quickly. When the water storage box 507 vibrates, it will also drive the tray 511 to vibrate. When the tray 511 vibrates, it can prevent the impurities inside the water storage box 507 from blocking the movement of the tray 511 or causing the tray 511 to be stuck. It can also remove any impurities that may exist in the gap between the water storage box 507 and the tray 511.

[0030] When the top of the tray 511 is filled with water, the free end of the elastic telescopic column 601 will move downward. When the free end of the elastic telescopic column 601 moves, it will drive the irregular rod 602 to move downward. When the irregular rod 602 moves downward, it will drive the L plate 603 to move downward. When the L plate 603 moves downward, it will release the limiting plate 607 at the bottom of the screen frame 604. When the limiting plate 607 at the bottom of the screen frame 604 is released, the screen frame 604 will move downward. When the screen frame 604 moves downward, it will block the front of the water storage box 507, so that more water can be stored inside the water storage box 507 and prevent liquid from flowing out. At the same time, when the screen frame 604 moves, it will drive the soft plate at the bottom of the water blocking plate 606 to move. When the soft plate at the bottom of the water blocking plate 606 moves, it will drive the water blocking plate 606 to move. When the water blocking plate 606 moves, it will seal the bottom of the water pipe 605. When the bottom of the water pipe 605 is sealed, the water pipe 605 cannot continue to supply water into the water storage box 507, thus preventing the water inside the water storage box 507 from becoming turbid again.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
