Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, and in particular to an environmental monitoring and sampling device for factory buildings. Background Technology

[0002] Powder coating manufacturing plants generate industry-specific pollutants due to the mixing, grinding, and sieving of materials such as resins, pigments, and fillers involved in the production process. They also need to meet multiple requirements for environmental protection, occupational health, and production safety.

[0003] Existing technologies, such as the utility model with publication number CN219796784U, disclose an ambient air comprehensive sampler, belonging to the field of air detection technology. It includes a base, a lifting component below the base, a placement frame above the base, a sampler body inside the placement frame, a fixing mechanism at the connection between the sampler body and the placement frame, and a protective component above the placement frame. This utility model, by incorporating the lifting component, achieves the effect of easily adjusting the height of the sampler body according to usage needs, improving its practicality. Furthermore, the protective component facilitates the protection of the sampler body after use, preventing dust and impurities from falling in and affecting its operation.

[0004] In the aforementioned technology, the protection of the sampler body when not in use requires manual operation, which increases the workload of the operators. During the gap between connecting the protective cover and the connecting frame, the top of the sampler body is easily affected by dust in the factory. Its base lacks ground adaptability and adjustment capabilities. Due to equipment installation and material stacking, the factory floor is prone to local bumps or depressions. It is impossible to adjust the support height according to the flatness of the ground. After placement, it is easy to tilt, causing the angle of the sampler body to shift, which further affects the sampling accuracy and even poses a risk of equipment tipping over. Utility Model Content

[0005] The purpose of this invention is to solve the problems of existing monitoring devices being complicated to operate during protection, easily allowing dust and impurities to enter, and being unstable and prone to tilting when deployed on uneven factory floors. Therefore, this invention proposes an environmental monitoring and sampling device for factory buildings.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an environmental monitoring and sampling device for factory buildings, comprising a support base, a placement tray, and a sampling module.

[0007] A placement plate is fixedly connected to the top of the support base. A damping telescopic device is fixedly connected to the center of the top of the placement plate. An electric push rod is fixedly connected to the top of the placement plate. A base is fixedly connected to the top of the damping telescopic device and the electric push rod. A sampling module is fixedly installed on the top of the base. A lifting mechanism is fixedly connected to the side of the base. A protective cover is threaded onto the outer surface of the lifting mechanism.

[0008] The lifting mechanism includes a mounting plate fixedly connected to the side of the base. A fixed frame is fixedly connected to the top of the mounting plate, and a motor is fixedly installed at the bottom of the mounting plate. A screw is fixedly connected to the output end of the motor, and the end of the screw away from the motor is rotatably connected to the inner wall of the fixed frame.

[0009] Furthermore, movable blocks are fixedly connected to both outer surfaces of the protective cover, and the movable blocks are threadedly connected to the outer surface of the screw. A viewing window is provided on the outer surface of the protective cover.

[0010] Furthermore, the lifting mechanism is symmetrically distributed on the outer surface of the base, and the screws on both sides are threadedly connected to the moving blocks.

[0011] Furthermore, the support base includes a main rod and a support rod, the main rod being fixedly connected to the center of the bottom of the placement plate, and the support rod being fixedly connected to the top of the outer surface of the main rod.

[0012] Furthermore, a connecting groove is provided on the outer surface of the main rod, and a sliding rod is fixedly connected inside the connecting groove.

[0013] Furthermore, the support rod includes a connecting ring fixedly connected to the outer surface of the main rod. A first movable block is fixedly connected to the outer surface of the connecting ring. A support rod is movably connected inside the first movable block. A second movable block is fixedly connected to the side of the support rod. A bracket is movably connected inside the second movable block. A third movable block is movably connected to the end of the bracket away from the second movable block. The third movable block is slidably connected to the slide rod.

[0014] Furthermore, the connecting grooves are arranged in three sets at circumferential intervals on the outer surface of the main rod, and each connecting groove is fixedly connected to a sliding rod. The support rod is provided with three sets on the outer surface of the main rod, which are slidably connected to the corresponding sliding rods.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the lifting mechanism works in conjunction with the protective cover. The motor drives the screw to rotate, which in turn moves the moving block and the protective cover up and down. When the device is not working, the protective cover can be lowered to completely cover the sampling module. The working process can be easily observed through the viewing window. When the device needs to perform sampling and testing, the dust cover can be raised to facilitate sampling. This frees up the hands during use, simplifies the operation steps, and solves the problems of complex operation and easy entry of dust and impurities in existing monitoring devices when performing protection.

[0016] 2. In this utility model, the three sets of support rods and sliding rods of the support base can be used to flexibly adjust the unfolding angle and support height of the support rods. When the factory floor is uneven, the sliding third movable block moves along the sliding rod, driving the bracket and support rod to adjust the angle, so that the bottom of the three sets of support rods are closely attached to the ground, forming a stable triangular support structure, which solves the problems of poor support stability and easy tilting in the prior art.

[0019] Please see Figure 1-5 This utility model provides a technical solution: an environmental monitoring and sampling device for factory buildings, including a support base 1, a placement tray 2, and a sampling module 3.

[0020] A placement plate 2 is fixedly connected to the top of the support base 1. A damping expansion joint 21 is fixedly connected to the center of the top of the placement plate 2. An electric push rod 22 is fixedly connected to the top of the placement plate 2. A base 4 is fixedly connected to the top of the damping expansion joint 21 and the electric push rod 22. A sampling module 3 is fixedly installed on the top of the base 4. A lifting mechanism 5 is fixedly connected to the side of the base 4. A protective cover 6 is threadedly connected to the outer surface of the lifting mechanism 5.

[0021] The specific configuration and function of its support base 1 and lifting mechanism 5 will be explained below.

[0022] In this embodiment: the lifting mechanism 5 includes a mounting plate 51 fixedly connected to the side of the base 4, a fixed frame 52 fixedly connected to the top of the mounting plate 51, a motor 53 fixedly installed at the bottom of the mounting plate 51, a screw 54 fixedly connected to the output end of the motor 53, and the end of the screw 54 away from the motor 53 is rotatably connected to the inner wall of the fixed frame 52.

[0023] The effects achieved by the above components are as follows: the mounting plate 51 provides a stable mounting base for the other components of the lifting mechanism 5, ensuring that the positions of each component are fixed; the fixing frame 52 provides a limiting and supporting function for the top of the screw 54, preventing the screw 54 from radially shifting during rotation; the motor 53, as a power source, can output a stable torque to drive the screw 54 to rotate; the screw 54 converts the power of the motor 53 into linear motion power through rotation, providing a transmission basis for the lifting of the protective cover 6, and realizing the transmission of lifting power and structural stability as a whole.

[0024] Specifically, movable blocks 61 are fixedly connected to both outer surfaces of the protective cover 6. The movable blocks 61 are threadedly connected to the outer surface of the screw 54. A viewing window 62 is provided on the outer surface of the protective cover 6.

[0025] The effects achieved by the above components are as follows: the moving block 61 and the screw 54 form a threaded engagement, which can convert the rotational motion of the screw 54 into its own linear lifting motion, thereby driving the protective cover 6 to lift synchronously; the viewing window 62 is made of transparent acrylic material, which not only does not obstruct the view and allows the operator to observe the structure of the sampling module 3 in real time, but also prevents dust and debris in the factory from entering the interior of the protective cover 6, while buffering the impact of accidental collisions on the sampling module 3, thus achieving the dual functions of protection and observation.

[0026] Specifically, the lifting mechanism 5 is symmetrically distributed on the outer surface of the base 4, and the screws 54 on both sides are threadedly connected to the moving block 61.

[0027] The effects achieved by the above components are as follows: the symmetrically distributed lifting mechanism 5 can provide lifting power from both sides of the protective cover 6 simultaneously, avoiding the tilting of the protective cover 6 due to force on one side; when the screws 54 on both sides rotate synchronously, the corresponding moving blocks 61 can maintain the same lifting speed, ensuring that the protective cover 6 always moves smoothly in the vertical direction, effectively preventing problems such as jamming and deviation during the lifting process, and improving the operational stability of the protective cover 6.

[0028] Specifically, the support base 1 includes a main rod 11 and a support rod 12. The main rod 11 is fixedly connected to the center of the bottom of the placement plate 2, and the support rod 12 is fixedly connected to the top of the outer surface of the main rod 11.

[0029] The effects achieved by the above components are as follows: the main rod 11, as the core load-bearing structure of the support base 1, can transfer the weight of the placement plate 2 and the components above it to the ground. Its hollow stainless steel material ensures load-bearing strength while reducing the overall weight of the device. The support rod 12, together with the main rod 11, forms a distributed support structure, avoiding the device from relying solely on the main rod 11 for single-point support. This further disperses the weight, improves the overall anti-tipping ability of the device, and lays the foundation for the stable placement of the device in the factory.

[0030] Specifically, the outer surface of the main rod 11 is provided with a connecting groove 111, and a slide rod 112 is fixedly connected inside the connecting groove 111.

[0031] The effects achieved by the above components are as follows: the connecting groove 111 provides installation space for the slide rod 112, and at the same time limits the sliding range of the third movable block 126, preventing the third movable block 126 from falling off the slide rod 112; the slide rod 112 has a high surface smoothness, which can greatly reduce the frictional resistance when the third movable block 126 slides, making the angle adjustment of the support rod 12 smoother, and the chrome plating layer can enhance the wear resistance and rust prevention of the slide rod 112, extending the service life of the components.

[0032] Specifically, the support rod 12 includes a connecting ring 121 fixedly connected to the outer surface of the main rod 11. A first movable block 122 is fixedly connected to the outer surface of the connecting ring 121. A support rod 123 is movably connected inside the first movable block 122. A second movable block 124 is fixedly connected to the side of the support rod 123. A bracket 125 is movably connected inside the second movable block 124. A third movable block 126 is movably connected to the end of the bracket 125 away from the second movable block 124. The third movable block 126 is slidably connected to the slide rod 112.

[0033] The effects achieved by the above components are as follows: the connecting ring 121 securely connects the support rod 12 to the main rod 11, ensuring that the overall structure of the support rod 12 does not loosen; the first movable block 122 allows the support rod 123 to rotate around it, the second movable block 124 allows the bracket 125 to rotate around it, and the third movable block 126 can slide along the sliding rod 112 and drive the bracket 125 to move. Through the cooperation of each movable block, the angle between the support rod 123 and the bracket 125 can be flexibly adjusted, thereby changing the extension range and support height of the support rod 12, so that the device can adapt to factory floors with different flatness.

[0034] Specifically, there are three sets of connecting grooves 111 distributed circumferentially on the outer surface of the main rod 11, and each connecting groove 111 is fixedly connected to a slide rod 112. The support rod 12 is provided with three sets on the outer surface of the main rod 11, which are slidably connected to the corresponding slide rod 112.

[0035] The effect achieved by the above components is that the three sets of connecting grooves 111 and the support rods 12 are evenly distributed in a circle to form an equilateral triangular support structure. Compared with the traditional two or four sets of supports, the equilateral triangular structure has stronger stability and can evenly distribute the weight of the device from three directions, further improving the stability of the device during use.

[0036] Working principle: The device is moved to the testing area in the factory. The third movable block 126 of the three sets of support rods 12 is pushed to slide along the corresponding slide rod 112, which drives the bracket 125 and the support rod 123 to rotate and adjust the angle so that the bottom of the three sets of support rods 12 is in close contact with the ground. At the same time, it is observed whether the placement plate 2 is horizontal until the entire device is placed stably, and the support adjustment is completed. According to the required testing height in the factory, the electric push rod 22 on the placement plate 2 is activated. The electric push rod 22 extends and retracts, which drives the base 4 and the sampling module 3 to move up and down. At the same time, the damping expansion joint 21 extends and retracts synchronously with the base 4 to absorb the vibration generated by the operation of the equipment in the factory. When the sampling module 3 reaches the target height, the electric push rod 22 is turned off, and the sampling height adjustment is completed. When sampling and testing are required, the motor 53 of the lifting mechanism 5 is activated. The motor 53 drives the screw 54 to rotate clockwise, and the moving block 61 moves upward along the screw 54 under the action of the thread, causing the protective cover 6 to rise synchronously. The protective cover 6 is opened, and then the sampling module 3 is activated. Through its internal sampling pump, detection sensors and other components, the air at the target height is sampled and indexed. The operator can observe the working status of the sampling module 3 in real time through the viewing window 62 of the protective cover 6. After the sampling and testing are completed, the motor 53 is activated to drive the screw 54 to rotate counterclockwise, causing the protective cover 6 to descend, preventing dust and other impurities in the factory from adhering to the surface of the sampling components and affecting the accuracy of the next sampling results.
