Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, specifically to a construction dust sampling device for environmental monitoring. Background Technology

[0002] Environmental supervision mainly refers to environmental supervision of construction projects. It means that environmental supervision agencies, entrusted by the project construction unit, supervise and manage the environmental protection of the project construction based on the environmental impact assessment documents, the approval of the environmental protection administrative department and the environmental supervision contract. Environmental supervision generally requires the installation of construction dust sampling devices at the construction site to sample and measure the dust at the construction site. The dust sampling results can also be displayed on an electronic display screen.

[0003] A search revealed a Chinese patent document disclosing a construction dust sampling device for environmental supervision [Announcement No.: CN216899802U]. This CN216899802U includes a main body for the dust sampling device, with a support frame fixed to the outside of the main body. The device is equipped with a shielding mechanism, allowing one end of the inclined support block on the outside of the shielding mechanism to be inserted into a pre-set slot in the support frame. The mounting plate on the outside of the shielding mechanism can fit snugly against the outside of the support frame.

[0004] The sampling device disclosed in this patent uses a shield to cover and protect the main body of the dust sampling device and the display screen, which avoids the situation of being easily wetted by rainwater on rainy days, reduces corrosion and extends the service life of the equipment. However, it still has shortcomings in actual use. Although it can protect the display screen and the main body of the dust sampling device, it requires the staff to operate it manually in the rain, which brings inconvenience to the staff. Utility Model Content

[0005] The purpose of this invention is to provide a construction dust sampling device for environmental supervision, so as to solve the problems existing in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a construction dust sampling device for environmental monitoring, comprising a support column, and further comprising:

[0007] A rotating rod is installed at the top of the support column. The top of the support column surface is rotatably connected to the rotating rod. A support plate is fixedly connected to the front end of the rotating rod. The top of the support plate is equipped with the main body of the dust sampling device. The top of the back of the support column is equipped with a drive structure for rotating the support plate.

[0008] A protective shell is fixed to the surface of the support column. A screw is rotatably connected inside the protective shell. A screw sleeve is threadedly connected to the surface of the screw. A display screen body is provided on the surface of the screw sleeve. The surface of the display screen body is movably connected to the inside of the protective shell.

[0009] A transmission structure located behind the protective shell and used to drive the screw to rotate is provided, and a control box is provided on the surface of the support column.

[0010] Preferably, the drive structure includes a motor fixed to the back of the support column, a first gear fixed to the output shaft of the motor, and a second gear fixed to the rear end of the rotating rod, wherein one side of the second gear meshes with the first gear.

[0011] Preferably, the transmission structure includes a driving wheel fixed to the rear end surface of the rotating rod, a driven wheel connected to the driving wheel via a belt, a movable rod fixed to one side of the driven wheel, a first bevel gear fixed to the other end of the movable rod, and a second bevel gear fixed to one end surface of the screw, wherein the surface of the first bevel gear meshes with one side of the second bevel gear.

[0012] Preferably, a fixing rod is fixedly connected inside the protective shell, and a movable sleeve is movably connected to the surface of the fixing rod, with the surface of the movable sleeve fixed to the back of the display screen body.

[0013] Preferably, a wiping cotton is fixedly connected to the front wall surface inside the protective shell, and the back of the wiping cotton is in contact with the surface of the display screen body.

[0014] Preferably, the rain sensor is electrically connected to the motor.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes the combined use of a rain sensor and a motor. When rainwater is detected, the rotating rod and support plate rotate, causing the main body of the dust sampling device to rotate downwards, thus facilitating the shielding of the dust sampling device. Simultaneously, as the rotating rod rotates, it also drives the screw to rotate through the transmission structure. Utilizing the threaded connection between the screw and the screw sleeve, the display screen body can be moved into the protective shell, thereby retracting the display screen body into the protective shell for protection. This reduces the hassle of manual retraction and protection, thus facilitating subsequent use. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 As shown, a construction dust sampling device for environmental monitoring includes a support column 1, a rotating rod 2 at the top of the support column 1, a support plate 3 fixedly connected to the top of the support column 1, a dust sampling device body 4 at the top of the support plate 3, a drive structure 5 for rotating the support plate 3 at the top of the back of the support column 1, a protective shell 6 fixed to the surface of the support column 1, a screw 7 rotatably connected inside the protective shell 6, a threaded sleeve 8 threadedly connected to the surface of the screw 7, a display screen body 9 on the surface of the threaded sleeve 8, and the surface of the display screen body 9 being movably connected to the inside of the protective shell 6. A transmission structure 11 for rotating the screw 7 is provided behind the protective shell 6, and a control box 10 is provided on the surface of the support column 1.

[0025] The drive structure 5 includes a motor 51, a first gear 52, and a second gear 53. The motor 51 is fixed to the back of the support column 1. The output shaft of the motor 51 is fixed to one side of the first gear 52. The interior of the second gear 53 is fixed to the other end surface of the rotating rod 2. One side of the second gear 53 meshes with the first gear 52. Thus, when the rotating rod 2 and the support plate 3 are rotated, the motor 51 can be started, which will drive the first gear 52 to rotate and simultaneously drive the second gear 53 to rotate. Since the size of the first gear 52 is smaller than that of the second gear 53, it can not only reduce speed but also save effort.

[0026] The transmission structure 11 includes a driving wheel 111, a driven wheel 112, a movable rod 113, a first bevel gear 114, and a second bevel gear 115. The interior of the driving wheel 111 is fixed to the rear end surface of the rotating rod 2. The driving wheel 111 is connected to the driven wheel 112 via a belt. One end of the movable rod 113 is fixed to one side of the driven wheel 112, and the other end of the movable rod 113 extends into the interior of the protective shell 6 and is fixed to one side of the first bevel gear 114. The second bevel gear 115 is fixed to the surface of one end of the screw 7. The surface of the first bevel gear 114 meshes with one side of the second bevel gear 115. Thus, as the rotating rod 2 rotates, it drives the driving wheel 111 to rotate. At the same time, the driven wheel 112, the movable rod 113, and the first bevel gear 114 rotate via the belt, which in turn drives the second bevel gear 115 and the screw 7 to rotate.

[0027] The protective shell 6 has a fixed rod 12 inside, and a movable sleeve 13 is movably connected to the surface of the fixed rod 12. The surface of the movable sleeve 13 is fixed to the back of the display screen body 9, which can help limit the display screen body 9 and facilitate its left and right movement.

[0028] A wiping cotton 15 is fixedly connected to the front wall surface inside the protective shell 6, and the back of the wiping cotton 15 is in contact with the surface of the display body 9. In this way, when the display body 9 moves into the protective shell 6, the dust on the surface of the display body 9 can be wiped and cleaned by the wiping cotton 15, which facilitates subsequent use.

[0029] The rain sensor 14 is electrically connected to the motor 51, so that when the rain sensor 14 detects rain, it will send an operation command to the motor 51 to facilitate subsequent operations.

[0030] It is worth noting that the technical features proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in the field. This technical solution will not elaborate further.

[0031] Working principle: During use, the support column 1 can be installed on the construction site. Under normal weather conditions, the display screen body 9 is always outside the protective shell 6, and the dust sampling device body 4 is also located above the support plate 3. When it rains, the rain sensor 14 will sense the rainwater and send an operation command to the motor 51, which will drive the rotating rod 2 and the support plate 3 to rotate, so that the dust sampling device body 4 is flipped to the bottom of the support plate 3, and the bottom of the support plate 3 is facing upward. At the same time, as the rotating rod 2 rotates, it will drive the screw 7 to rotate through the transmission structure 11, and drive the screw sleeve 8 and the display screen body 9 to move to the left, so that the display screen body 9 can be stored inside the protective shell 6.

[0032] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0033] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
