[0002] A confined space is a closed or partially enclosed space with narrow and limited entrances and exits, not designed as a fixed workplace, poor natural ventilation, and a high risk of toxic, harmful, flammable, or explosive substances accumulating or insufficient oxygen. Working in confined spaces presents numerous safety risks, such as oxygen deficiency, poisoning, explosions, and fires. Therefore, a rigorous safety assessment and preparation must be conducted before any confined space work to ensure the safety of personnel.

[0003] Confined space work refers to work activities carried out within enclosed or partially enclosed confined spaces.

[0004] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. When cleaning the inside of a pipe, the existing confined space operation device often cannot flexibly adjust the position of the cleaning component according to the specific depth and diameter of the pipe, thus affecting subsequent operations; 2. The existing confined space operation device often requires the operator to manually move the entire device to the work site and manually clean the inside of the pipe, which is time-consuming and labor-intensive. Utility Model Content

[0005] The purpose of this utility model is to provide a confined space operation device that can be adjusted according to width and length, to solve the problems mentioned in the background art. Existing confined space operation devices often struggle to flexibly adjust the position of the cleaning components according to the specific depth and diameter of the pipe when cleaning the inside of the pipe, thus affecting subsequent operations. Furthermore, existing confined space operation devices often require operators to manually move the entire device to the work site and manually clean the inside of the pipe, which is time-consuming and labor-intensive. To achieve the above objective, this utility model provides the following technical solution: A confined space operation device that can be adjusted according to width and length, including a moving mechanism. The bottom end of the moving mechanism vertically penetrates the top of a base plate. A water storage tank is located in the middle of the top of the base plate. A water delivery mechanism vertically penetrates the middle of the top of the water storage tank. Several water distribution pipes are transversely inserted through the inner walls of both sides of the water delivery mechanism. Brush rings are provided at the tail ends of the several water distribution pipes. A rotating mechanism is sleeved on the outer wall of the water delivery mechanism. The bottom end of the rotating mechanism vertically penetrates one side of the top of a support groove. Clamping mechanisms are transversely inserted through the left and right sides of the support groove.

[0006] More preferably, the moving mechanism includes a hydraulic cylinder and a caster wheel, the driving end of the hydraulic cylinder is vertically inserted through the top of the base plate, and the caster wheel is screwed to the driving end of the hydraulic cylinder.

[0007] More preferably, the water delivery mechanism includes a telescopic pipe, an electric actuator, a connecting collar, a water pump, a water pumping pipe, and a slider. The bottom end of the water pumping pipe vertically penetrates the middle of the top of the water storage tank. The top end of the water pumping pipe is connected to the water pump, and the top end of the water pump is connected to the telescopic pipe. One end of the connecting collar is sleeved on the outer wall of the top end of the telescopic pipe, and the other end of the connecting collar is sleeved on the outer wall of the drive end of the electric actuator. Water distribution pipes are inserted into both sides of the telescopic pipe, and the bottom end of the electric actuator is provided with a slider.

[0008] More preferably, the water distribution pipe is slidably connected to an extension pipe inside, and a compression spring is provided between the inner wall of the water distribution pipe and the extension pipe.

[0009] More preferably, a sliding groove is provided in the middle of the top of the support groove, and the sliding groove and the slider form a sliding connection.

[0010] More preferably, the rotating mechanism includes a drive motor, a rotating shaft, a drive gear, and a driven gear. The output end of the drive motor is inserted into the top end of the rotating shaft, and the bottom end of the rotating shaft penetrates vertically through one side of the top of the support groove. The drive gear is sleeved on the outer wall of the rotating shaft, and the driven gear is sleeved on the bottom outer wall of the telescopic tube. The drive gear and the driven gear mesh with each other.

[0011] More preferably, the clamping mechanism includes an electric telescopic rod and a clamping ring, wherein the driving end of the electric telescopic rod extends laterally through the left and right outer walls of the support groove, and the driving end of the electric telescopic rod is provided with a clamping ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In this invention, the universal wheels allow the entire device to move freely, making it easy for operators to move it to the desired location. The hydraulic cylinder allows for precise adjustment of the base plate height, enabling the device to adapt to pipes of varying depths. The clamping mechanism ensures the entire working device is stably fixed at the pipe, preventing it from loosening or moving. The secure clamping also prevents accidental detachment of components during operation, ensuring operator safety. Furthermore, by adjusting the length of the electric telescopic rod, the clamping ring can adapt to pipes of different diameters, improving the device's versatility. The rotating mechanism drives the telescopic pipe, water distribution pipe, and brush ring to rotate synchronously, allowing the rotating brush ring to more comprehensively cover the inner wall of the pipe, ensuring full contact with dirt and sediment. The rotating brush can quickly remove dirt and sediment from the pipe, shortening cleaning time and improving work efficiency.

[0014] In this invention, the electric actuator can drive the telescopic tube to move up and down via a connecting collar, thereby flexibly adjusting the length of the telescopic tube. This allows for adjustment of the position and coverage of the brush ring according to the specific depth of the pipe. Repeated raising and lowering of the telescopic tube generates friction and impact between the brush ring and the inner wall of the pipe, removing dirt and deposits and improving cleaning efficiency. The extension tube can slide laterally within the water distribution pipe, adapting to pipes of different diameters. The extension tube's self-extension and contraction pushes the brush ring laterally, preventing it from failing to adhere to the inner wall of the pipe. The compression spring provides a restoring force when the extension tube retracts, pushing it back to ensure the brush ring fits tightly against the inner wall of the pipe. This ensures the brush ring maintains good contact with the inner wall of the pipe throughout the cleaning process, improving cleaning effectiveness. Attached Figure Description

Detailed Implementation

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 5 This utility model provides a technical solution: a limited space operation device with adjustable width and length, including a moving mechanism 1, the bottom end of the moving mechanism 1 vertically penetrating the top of the base plate 2, a water storage tank 3 provided in the middle of the top of the base plate 2, a water delivery mechanism 4 vertically penetrating the middle of the top of the water storage tank 3, a plurality of water distribution pipes 5 horizontally penetrating the inner walls on both sides of the water delivery mechanism 4, a brush ring 6 provided at the tail end of the plurality of water distribution pipes 5, a rotating mechanism 7 sleeved on the outer wall of the water delivery mechanism 4, the bottom end of the rotating mechanism 7 vertically penetrating one side of the top of the support groove 8, and clamping mechanisms 9 horizontally penetrating the left and right sides of the support groove 8.

[0023] In this embodiment, as Figure 1 and Figure 5As shown, the moving mechanism 1 includes a hydraulic cylinder 101 and casters 102. The driving end of the hydraulic cylinder 101 extends vertically through the top of the base plate 2, and the casters 102 are screwed onto the driving end of the hydraulic cylinder 101. It should be noted that the operator can first move the entire device to a designated location using the casters 102, so that the base plate 2 is directly below the pipe. Then, the four hydraulic cylinders 101 in all directions are activated simultaneously, causing their driving ends to extend downwards and push the casters 102 connected to them to begin descending. Because the casters 102 are in contact with the ground, the entire base plate 2 will be lifted by the continuously extending driving ends of the hydraulic cylinders 101 until the water delivery mechanism 4 and the water distribution pipe located at the top of the base plate 2 are lifted. 5 and the brush ring 6 are fully inserted into the pipe to facilitate subsequent cleaning operations. In actual use, the casters 102 allow the entire device to move freely, making it easy for operators to move it to the required position. By simultaneously activating the four hydraulic cylinders 101, the height of the base plate 2 can be precisely adjusted, enabling the entire device to adapt to pipes of different depths. The hydraulic cylinders 101 also provide stable support, ensuring that the base plate 2 remains stable during raising and lowering. Furthermore, the entire lifting and lowering operation of the device is fully automated. Operators only need to control the switches of the hydraulic cylinders 101 to complete the lifting and lowering actions, thus facilitating operations within limited spaces.

[0024] In this embodiment, as Figure 2 and Figure 3As shown, the water delivery mechanism 4 includes a telescopic pipe 401, an electric actuator 402, a connecting collar 403, a water pump 404, a water pumping pipe 405, and a slider 406. The bottom end of the water pumping pipe 405 vertically penetrates the middle of the top of the water storage tank 3. The top end of the water pumping pipe 405 is connected to the water pump 404, and the top end of the water pump 404 is connected to the telescopic pipe 401. One end of the connecting collar 403 is sleeved on the outer wall of the top end of the telescopic pipe 401, and the other end of the connecting collar 403 is sleeved on the outer wall of the drive end of the electric actuator 402. Water distribution pipes 5 are inserted into both sides of the telescopic pipe 401. The bottom end of the electric actuator 402 is equipped with a slider 406. It should be noted that when the operator lifts the base plate 2 using the hydraulic cylinder 101, allowing the water delivery mechanism 4, water distribution pipe 5, and brush ring 6 to all extend into the pipe, the operator can first start the water pump 404 and extract the clean water stored in the inner wall of the water storage tank 3 through the connected water pipe 405. This clean water is then pushed upwards into the telescopic pipe 401. Simultaneously, the water pump 404 continues to generate thrust, pushing the clean water upwards along the telescopic pipe 401. During this process, the clean water flows sequentially through the telescopic pipe. Water flows into the distribution pipe 5, which is inserted into the outer wall of pipe 401, until it reaches the brush ring 6 connected to the distribution pipe 5, wetting the bristles and making contact with the inner wall of the pipe. Simultaneously, the operator can activate the rotating mechanism 7 and the electric actuator 402. The drive end of the electric actuator 402, through the connecting collar 403, drives the telescopic pipe 401 to repeatedly rise and fall, thus allowing the bristles of the brush ring 6 to mix with clean water and clean the inner wall of the pipe. In actual use, the electric actuator 402 can drive the telescopic pipe 401 to move up and down through the connecting collar 403, thereby achieving the cleaning of the telescopic pipe 401. The flexible adjustment of the length allows for adjustment of the position and coverage of the brush ring 6 according to the specific depth of the pipe. By repeatedly raising and lowering the telescopic tube 401, friction and impact can be generated between the brush ring 6 and the inner wall of the pipe, removing dirt and deposits from the inner wall of the pipe and improving the cleaning effect. The water pump 404 can quickly deliver clean water from the water tank 3 to the telescopic tube 401 to ensure sufficient water supply during the cleaning process. At the same time, the water pump 404 has high working efficiency and can deliver a large amount of clean water to the brush ring 6 through the telescopic tube 401 in a short time, thereby improving the cleaning efficiency.

[0025] In this embodiment, as Figure 4As shown, an extension pipe 501 is slidably connected inside the water distribution pipe 5. A compression spring 502 is provided between the inner wall of the water distribution pipe 5 and the extension pipe 501. It should be noted that when the operator lifts the base plate 2 using the hydraulic cylinder 101, causing the water delivery mechanism 4, the water distribution pipe 5, and the brush ring 6 to extend into the pipe, the brush ring 6 connected to the extension pipe 501 will first contact the inner wall of the pipe. Due to the limitation of the pipe diameter, the brush ring 6 is pushed towards the center, causing the extension pipe 501 to slide laterally into the water distribution pipe 5 when pushed, and also compressing the compression spring 502, causing it to deform. After the complete water distribution pipe 5 is inserted into the pipe, the compression spring 502 will push the extension pipe 501 back, so that the brush ring 6 at the front end of the extension pipe 501 can fit tightly against the inner wall of the pipe. When the operator starts the water delivery mechanism 4... When water is supplied, the clean water flows into the water distribution pipe 5 and then laterally through the extension pipe 501 to the brush ring 6 to wet the bristles. At the same time, driven by the rotating mechanism 7 and the electric push rod 402, the limited pipe space is cleaned. In actual use, the extension pipe 501 can slide laterally inside the water distribution pipe 5, thus adapting to pipes of different diameters. Through the self-extension and contraction of the extension pipe 501, the lateral position of the brush ring 6 can be pushed, thus preventing the brush ring 6 from not adhering to the inner wall of the pipe. The compression spring 502 can provide a relative restoring force when the extension pipe 501 retracts, so that after the extension pipe 501 is fully inserted into the pipe, it can push the extension pipe 501 back, so that the brush ring 6 fits tightly against the inner wall of the pipe, thus ensuring that the brush ring 6 always maintains good contact with the inner wall of the pipe during the cleaning process and improving the cleaning effect.

[0026] In this embodiment, as Figure 2 and Figure 3 As shown, a sliding groove 801 is provided in the middle of the top of the support groove 8, and the sliding groove 801 and the slider 406 are slidably connected. It should be noted that when the operator starts the water supply mechanism 4 to evenly deliver clean water into the multiple water distribution pipes 5 and simultaneously wets the bristles of the corresponding brush rings 6, the operator can simultaneously start the rotating mechanism 7 and the electric push rod 402. Starting the rotating mechanism 7 can drive the entire water supply mechanism 4 to start rotating, and at the same time, the electric push rod 402 will be rotated along with it. The slider 406 located at its bottom edge conforms to the inner wall of the groove 801 for stable rotational movement. In actual use, the slider 406 can slide freely within the groove 801, thereby providing stable support for the electric actuator 402 and preventing it from shaking or shifting during rotation. The annular inner wall of the groove 801 can restrict the movement trajectory of the slider 406, thereby ensuring the smooth movement of the electric actuator 402 and avoiding jamming or shaking, while ensuring that it rotates synchronously with the telescopic tube 401.

[0027] In this embodiment, as Figure 3 As shown, the rotating mechanism 7 includes a drive motor 701, a rotating shaft 702, a driving gear 703, and a driven gear 704. The output end of the drive motor 701 is inserted into the top of the rotating shaft 702, and the bottom end of the rotating shaft 702 vertically penetrates one side of the top of the support groove 8. The driving gear 703 is sleeved on the outer wall of the rotating shaft 702, and the driven gear 704 is sleeved on the bottom outer wall of the telescopic tube 401. The driving gear 703 and the driven gear 704 mesh with each other. It should be noted that when the operator starts the water supply mechanism 4 to evenly deliver clean water into the multiple water distribution pipes 5 and simultaneously wets the bristles of the corresponding brush rings 6, the operator can simultaneously start the rotating mechanism 7 and the electric push rod 402. The drive motor 701 can be started to drive the rotating shaft 702, which is inserted with it, to start rotating. At the same time, the driving gear 703, which is sleeved on the outer wall of the rotating shaft 702, will also be driven to rotate together, and the driven gear 704 meshes with the support groove 8 on one side of the driving gear 703. Driven gear 704 transmits the rotational force it receives to itself, causing the telescopic tube 401 inside it, as well as the water distribution pipes 5 and brush rings 6 located on both sides of the telescopic tube 401, to rotate synchronously. This allows the bristles of the brush rings 6 to adhere to the inner wall of the pipe for a rotating cleaning operation. In actual use, the rotating mechanism 7 drives the telescopic tube 401, water distribution pipes 5, and brush rings 6 to rotate synchronously, enabling the rotating brush rings 6 to more comprehensively cover the inner wall of the pipe and fully contact dirt and sediment. Rotational cleaning can quickly remove dirt and sediment from the pipe, shorten cleaning time, and improve work efficiency. Furthermore, due to the rotational movement of the brush rings 6, pressure can be evenly distributed within the pipe, avoiding localized over-cleaning or under-cleaning and ensuring consistent cleaning quality. Compared to traditional linear cleaning methods, the rotational cleaning by the rotating mechanism 7 can further increase cleaning power, thereby enhancing the cleaning effect.

[0028] In this embodiment, as Figure 2 and Figure 3As shown, the clamping mechanism 9 includes an electric telescopic rod 901 and a clamping ring 902. The driving end of the electric telescopic rod 901 extends laterally through the outer walls of the left and right sides of the support groove 8, and the driving end of the electric telescopic rod 901 is equipped with a clamping ring 902. It should be noted that when the operator raises the entire base plate 2 by activating the hydraulic cylinder 101, so that the water supply mechanism 4, water distribution pipe 5, and brush ring 6 located on the top of the base plate 2 are all inserted into the pipe, the bottom wall of the support groove 8 will also be tightly fitted to the bottom end of the pipe. At the same time, the operator activates the electric telescopic rods 901 on both sides laterally through the external controller, and pushes the clamping ring 902 connected to them toward the middle of the pipe, until the clamping ring 902... The opposite sides of 02 can fit tightly against the outer walls of both sides of the pipe, thus firmly fixing the entire working device to the pipe. In actual use, the electric telescopic rod 901 can provide reliable clamping force for the clamping ring 902, ensuring that the entire working device is stably fixed at the pipe, making it difficult to loosen or move. The stable clamping can prevent the various parts of the working device from accidentally falling off during operation, thereby ensuring the safety of the operator. At the same time, by adjusting the length of the electric telescopic rod 901, the clamping ring 902 can be adapted to pipes of different diameters, improving the versatility of the device. The rapid response of the electric telescopic rod 901 can realize the quick fixing and loosening of the clamping ring 902, thereby reducing installation and disassembly time and improving work efficiency.

[0029] The method of use and advantages of this utility model: This limited space operation device, which is adjustable according to width and length, operates as follows:

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the operator can first move the entire device to a designated location using the casters 102, so that the base plate 2 is directly below the pipe. Then, the four hydraulic cylinders 101 are activated simultaneously, causing their drive ends to extend downwards and push the casters 102 connected to them to begin descending. Because the casters 102 are against the ground, the entire base plate 2 is lifted by the continuously extending drive ends of the hydraulic cylinders 101 until the water delivery mechanism 4, water distribution pipe 5, and brush ring 6 located on the top of the base plate 2 are all inserted into the pipe. During this process, the brush ring 6 connected to the extension pipe 501 will first contact the inner wall of the pipe, and due to the limitation of the pipe diameter, the brush ring 6 will be pushed towards the center, causing the extension pipe 501 to... When pushed, it slides laterally into the interior of the water distribution pipe 5, compressing and deforming the compression spring 502. After the complete water distribution pipe 5 is inserted into the pipe, the compression spring 502 pushes back against the extension pipe 501, allowing the brush ring 6 at the front end of the extension pipe 501 to fit tightly against the inner wall of the pipe, and the bottom wall of the support groove 8 to fit tightly against the bottom end of the pipe. At the same time, the operator activates the electric telescopic rods 901 on both sides through the external controller to extend laterally and pushes the clamping rings 902 connected to them toward the middle of the pipe until the opposite sides of the clamping rings 902 fit tightly against the outer walls of both sides of the pipe. This secures the entire working device to the pipeline. The operator can then start the water pump 404 and extract the clean water stored in the inner wall of the water tank 3 via the connected water pipe 405. The clean water is then pushed upwards into the telescopic pipe 401 and continues to flow upwards along the pipe. During this process, the clean water flows sequentially through the water distribution pipe 5 connected to the outer wall of the telescopic pipe 401 and into it until it reaches the brush ring 6 connected to the water distribution pipe 5, wetting the brush bristles and contacting the inner wall of the pipe. Simultaneously, the operator can activate the rotating mechanism 7 and the electric actuator 402. The drive end of the electric actuator 402 is connected to the connecting collar 40. 3. The telescopic tube 401 is repeatedly raised and lowered, so that the bristles of the brush ring 6, mixed with clean water, clean the inner wall of the pipe. The drive motor 701 drives the rotating shaft 702, which is inserted into it, to start rotating. At the same time, the drive gear 703, which is sleeved on the outer wall of the rotating shaft 702, is also driven to rotate. The rotational force received by the drive gear 703 is transmitted to the driven gear 704 through the driven gear 704 on one side. This allows the telescopic tube 401, the water distribution pipe 5 and the brush ring 6 on both sides of the telescopic tube 401 to rotate synchronously, so that the bristles of the brush ring 6 can adhere to the inner wall of the pipe and perform a rotating cleaning operation.
