Description

Technical Field

[0001] This utility model relates to the technical field of foldable dustproof sheds, specifically a foldable dustproof shed for the installation of GIS combined electrical equipment. Background Technology

[0002] During the installation and construction of GIS combined electrical equipment, dustproof sheds are key facilities to ensure the cleanliness of the equipment installation environment. They can effectively block external dust and debris from entering the installation area and avoid the equipment's insulation performance from deterioration or malfunction due to the adhesion of pollutants. At present, the dustproof sheds commonly used in the industry for GIS combined electrical equipment installation are mainly fixed frame dustproof sheds.

[0003] Fixed frame dustproof sheds are constructed by erecting a fixed structure with insulated brackets and then covering it with curtains to form a closed space. Although they can provide a stable dustproof effect, the frame is bulky, and transportation and on-site assembly require a lot of manpower and resources. They cannot flexibly adjust the coverage area according to the equipment installation progress, have poor compatibility with different specifications of GIS equipment, and the curtains need to be disassembled and stacked piece by piece when they are put away, which is time-consuming and labor-intensive, and it is difficult to achieve rapid storage of the curtains.

[0004] Therefore, there is an urgent need to develop a foldable dustproof shed that can be quickly deployed and retracted over long distances and is adaptable to different installation scenarios, so as to improve the installation efficiency and ease of use of GIS combined electrical equipment. Summary of the Invention

[0005] The purpose of this utility model is to provide a foldable dustproof shed for the installation of GIS combined electrical equipment, which aims to solve the problems of difficult curtain retraction and poor adaptability of insulation brackets in the prior art.

[0006] To achieve the above objectives, this utility model provides the following device: a foldable dustproof shed for the installation of GIS combined electrical equipment, comprising a frame body, a curtain on the outside of the frame body, a lifting device on the curtain, a traction rope installed on the lifting device for driving the curtain to fold, and a reset rope installed on the lifting device for driving the curtain to unfold. The traction rope and the reset rope work together to form a complete curtain opening and closing mechanism, allowing the dustproof shed to flexibly switch states according to actual usage needs.

[0007] A crossbar is installed at the top of the curtain. A traction wheel is rotatably mounted on one end of the crossbar via a bearing. A semi-circular groove is opened on the traction wheel. A limit block is fixedly installed on the outside of the traction wheel. A groove matching the size of the semi-circular groove is opened on the side of the limit block opposite to the traction wheel. The traction rope is a beaded rope formed by several fixed traction beads. Half of the beaded rope is located inside the groove, and the other half is located inside the groove. The crossbar, traction wheel, and other structures form a stable transmission connection by means of the beaded rope and the groove and groove, so that pulling the beaded rope can reliably drive the traction wheel to rotate. At the same time, the limit block and other structures ensure the stability of the position of the beaded rope during transmission, improving the smoothness and reliability of the lifting operation.

[0008] A ratchet is coaxially mounted on one side of the traction wheel. The traction wheel and ratchet rotate synchronously and are mounted on one end of a crossbar. The traction wheel and ratchet are restricted to rotating in opposite directions by a pawl. The pawl is mounted on a limit block via a support column, and the pawl and support column are rotatably connected. A hole is provided on the support column, and one end of a reset rope passes through the hole and connects to the pawl. A spring is fitted on the reset rope between the hole and the pawl. The ratchet and pawl work together to lock the traction wheel in one direction, ensuring that the curtain remains in its folded state. The reset rope, spring, etc., constitute a reset mechanism. When the curtain needs to be unfolded, pulling the reset rope releases the pawl lock, allowing the curtain to unfold by its own weight, making the unfolding operation more convenient and maintaining a stable folded and unfolded state.

[0009] Multiple frames are installed on the outside of the curtain, and the frames are hinged to each other. A metal semi-ring is provided between two adjacent frames. The pull bead rope has a closed structure. One end of the pull bead rope passes through the metal semi-ring and is fixedly connected to the bottom frame. The frames provide support for the curtain and facilitate folding. The hinged connection ensures that the frames can rotate along a single axis at one end. The metal semi-ring, together with the closed pull bead rope, enables the frames to fold or unfold synchronously when the pull bead rope is pulled, making the curtain fold more neatly and smoothly, and improving the overall folding effect and practicality of the dustproof awning.

[0010] The main frame also houses an environmental control system, which includes at least an air conditioner, a temperature and humidity monitor, and an air purifier. This system creates suitable environmental conditions for the operation of the GIS combined electrical equipment within the dustproof shed. By regulating temperature and humidity and purifying the air, it ensures the quality of the installation environment and facilitates stable installation and subsequent operation of the equipment.

[0011] The curtain has connection ports that connect to the corresponding positions of air conditioners, air purifiers, and GIS combined electrical equipment. These connection ports facilitate the connection of these devices to the external space, ensuring the proper functioning of the environmental control components while allowing the GIS equipment to connect to relevant external facilities without affecting the overall sealing and functionality of the dustproof shed.

[0012] The main frame is composed of supports, and the frame is connected in the middle by telescopic rods, which can change the size of the main frame to adapt to GIS combined electrical equipment of different specifications and sizes. This enhances the versatility and flexibility of the dustproof shed, and makes it easy to adjust in different installation scenarios to achieve the best dustproof and operating space effect.

[0013] The main frame is equipped with ladders and platforms. The ladders are fixedly connected to the main frame, and the platforms are horizontally set inside the main frame and connected to the support. The ladders and platforms provide support structures for installers to climb and operate, making it convenient for personnel to reach different heights to install, debug, and perform other operations on GIS equipment, thereby improving the convenience and safety of installation operations.

[0014] The bottom of the main frame is equipped with casters with brakes, which make the dustproof shed easy to move as a whole and can be flexibly adjusted according to the installation location of the GIS equipment; the braking function can also fix the position of the dustproof shed when needed, ensuring the stability of the dustproof shed during installation, combining ease of movement and stability of use.

[0015] Compared with the prior art, the beneficial effects of this utility model are: Fast and efficient folding and unfolding function: The curtain can be quickly folded and unfolded by means of frame hinge and lifting device. The operation is simple and easy to learn, reducing the time spent on manual operation and improving the continuity of operation. The frame structure ensures the stability of the curtain shape and improves the dustproof effect.

[0016] Stable and reliable positioning and self-locking: The structure of traction wheel, ratchet and pawl ensures that the curtain can stay stably at any height during the lifting process, realize self-locking, and effectively prevent the curtain from accidentally sliding down due to its own weight, with high safety and reliability.

[0017] It is flexible and convenient: the main frame is assembled from telescopic poles and brackets and equipped with casters, which makes it flexible to move and arrange. It can adapt to the size requirements of different spaces and equipment. The internal ladder and platform are installed, and the external connection ports are provided, which greatly improves the efficiency of equipment installation, commissioning and maintenance.

[0020] 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.

[0021] This embodiment provides a foldable dustproof shed for the installation of GIS combined electrical appliances 24 equipment.

[0022] like Figure 1 As shown, the main frame consists of an insulating bracket 11 and a telescopic rod 12. The height of the main frame is determined by the height of the GIS combined electrical appliance 24 device, which is achieved by adjusting the number of brackets 11. The length of the telescopic rod 12 is determined by the width of the GIS combined electrical appliance 24 device, and is adjustable, making it suitable for GIS combined electrical appliance 24 devices of different sizes.

[0023] Four sets of casters 14 with brakes are installed at the bottom of the main frame for easy movement. Ladders 13 and platforms 15 are installed inside the frame for workers to climb and work at height. An air conditioner 21, a temperature and humidity monitor 22, and an air purifier 23 are installed inside the main frame. The air purifier 23 is placed on the left working platform 15 to circulate and purify the internal air. The air conditioner 21 is fixed at the bottom of the left bracket 11 with the air outlet facing into the dustproof shed to regulate the internal temperature and ensure a constant temperature in the construction environment. The temperature and humidity monitor 22 is installed with a clip in the middle of the left bracket 11 and is connected to a mobile APP via Bluetooth to monitor the temperature and humidity inside the dustproof shed in real time.

[0024] like Figure 2 As shown, a foldable curtain 43 is installed on the frame body. First, the crossbar 41 at the top of the curtain 43 is fixed to the bracket 11 at the top of the frame body with a belt or bolt. The curtain 43 can be quickly raised and lowered by the lifting device 3 to achieve the function of quick opening and closing.

[0025] like Figure 3 As shown, the lifting device 3 includes a traction wheel 34, a limiting block 35, a beaded rope 31, a reset rope 38, a ratchet 37, and a pawl 36. The traction wheel 34 has a semi-circular groove 32, which is coaxially fixed with the ratchet 37. The limiting block 35 is fixedly installed on the outside of the traction wheel 34. The limiting block 35 has a sliding groove 39 on one side relative to the traction wheel 34, which is adapted to the size of the semi-circular groove 32, to ensure that half of the beaded rope 31 is stuck in the groove 32 and the other half slides in the sliding groove 39. The limiting block 35 has a support column with a hole. One end of the reset rope 38 passes through the hole and the other end is connected to the pawl 36. A spring 33 is sleeved on the reset rope 38 between the hole and the pawl 36. The spring 33 can prevent the pawl 36 from disengaging from the ratchet 37 under the action of gravity, and can also ensure that the pawl 36 locks the ratchet 37 when the ratchet 37 rotates.

[0026] The other end of the ratchet 37 is connected to the crossbar 41 via a bearing. Pulling the beaded rope 31 drives the traction wheel 34 to rotate the ratchet 37. When the traction rope is stopped, the curtain 43 rotates the ratchet 37 in the opposite direction due to gravity. At this time, the pawl 36 engages between the two ratchet wheels 37 to prevent the curtain 43 from falling further. The structure of the ratchet 37 and the pawl 36 ensures that the traction wheel 34 rotates in one direction.

[0027] To lower the curtain 43, pull the reset rope 38. The reset rope 38 passes through the hole on the support column of the limit block 35, causing the pawl 36 to disengage from the ratchet 37. The ratchet 37 then rotates freely. At this time, the curtain 43 drives the traction wheel 34 to rotate. When it descends to the appropriate position, release the pawl 36. Under the action of the spring 33, the pawl 36 engages between the two ratchet 37, restoring the locking effect of the pawl 36 on the ratchet 37. At this time, the curtain 43 stops falling. The position of the curtain 43 can be adjusted by the lifting device 3 to achieve the ideal position, making it convenient for the operator to carry out the work.

[0028] like Figures 4-5 As shown, the frames 42 are connected by hinges, which ensure that the frames 42 can rotate along a single axis at one end. The sides of the frames 42 are fixedly connected to the curtain 43. There is a metal semi-ring 44 between every two frames 42. The pull cord 31 has a closed structure. One end of the pull cord 31 is fixedly connected to the bottom frame 42 and passes through the metal semi-ring 44. When the pull cord 31 is pulled, the bottom frame 42 flips outward and folds together with the frame 42 one position apart. At the same time, the ends of adjacent frames 42 that are not connected to the pull cord 31 fold together. This structure ensures that the curtain 43 is generally folded in a "W" shape when the pull cord 31 is pulled. The frame body is provided with a matching foldable curtain 43 on all four sides.

[0029] After completing the task, the curtain 43 is fully lowered. The frame 42 is equipped with a magnetic structure, which can automatically attract the curtains 43 on both sides when lowered. The top of the frame body is also equipped with a curtain 43, which is connected to the curtains 43 around the frame by Velcro or magnets to ensure the airtightness of the dustproof canopy and prevent dust from entering.

[0030] like Figure 2 As shown, the curtain 43 has a connection port 45. The connection port 45 can be opened according to the needs of the GIS combined electrical appliance 24, air purifier 23 and air conditioner 21. After the curtain 43 is assembled, the connection port 45 is connected to the corresponding equipment. When the curtain 43 needs to be raised, the connection port 45 needs to be separated from the corresponding equipment before raising it to prevent the curtain 43 from being damaged.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
