Description

Technical Field

[0001] The present invention relates to a zero-fire and spark-free electromechanical pipeline reconstruction process for existing medical buildings, and in particular to a zero-fire and spark-free electromechanical pipeline reconstruction process for existing medical buildings applied in the field of construction. Background Art

[0002] The hospital has a complex and diverse pipeline system: including water supply and drainage systems, power supply systems, medical gas systems, communication network systems, etc. The various pipelines are intricate and intertwined, which makes the demolition work not only large in quantity but also technically demanding. In addition, hospitals are crowded places and there are many patients who need special care. Therefore, during the pipeline demolition process, construction safety must be ensured to avoid any damage to personnel and facilities.

[0003] In order to solve the problem of difficulty in hospital pipeline renovation, a certain air-conditioning pipeline in the market adopts a clip-on design and has a certain market share.

[0004] The specification of Chinese patent CN222278736U discloses an air-conditioning connecting pipeline in a factory area, which transforms the connecting pipeline between the air-conditioning surface cooler and the outside of the factory building, and adds a rotating plate that can be adjusted in position in the pipeline, and the rotating plate is connected and fixed to the first clamping block and the second clamping block respectively by the cooperation of the clamping mechanism and the clamping groove. When the air-conditioning is not needed for cooling in winter, the pipeline body is closed by clamping the rotating block with the first clamping block, and the external cold air is isolated, so as to further protect the surface cooler in the air-conditioning, and prevent the invasion of the external cold air from causing frostbite damage to the surface cooler of the air-conditioning. When the air-conditioning is needed for cooling in summer, the rotating plate is clamped and fixed with the second clamping block, so that the pipeline body is connected with the surface cooler of the air-conditioning, and the air exchange can be carried out normally to complete the cooling in the factory building. The surface cooler of the air-conditioning can be effectively protected in winter through the connecting pipeline, and the probability of the air-conditioning surface cooler being damaged by frostbite is further reduced, and the maintenance cost of the air-conditioning surface cooler is saved.

[0005] The specification of Chinese patent CN219756563U discloses an air duct of an air conditioner modified from a smoke exhaust duct. The air duct is provided with a movable connection between a clamping block and a dustproof grid, so that the clamping block can be rotated to disengage the clamping block and the dustproof grid, so as to facilitate the removal of the dustproof grid when cleaning the duct. The first sealing strips are provided at both ends of the first duct, so that when the first duct and the second duct are closed, the first sealing strips improve the sealing performance of the first duct and the second duct when they are closed. The fixing blocks are provided at both ends of the second duct, so that the fixing blocks are inserted into the limiting groove to close the second duct and the first duct. The screws are threadedly connected to the fixing blocks, so that the screws can fix the second duct and the first duct. The motor and the fan are fixedly connected, so that the motor transmits power to drive the fan to rotate, and the airflow in the duct is discharged to the outside of the duct during the rotation of the fan.

[0006] Although the existing air-conditioning ducts use convenient clamping devices during the renovation process, they cannot bend and expand adaptively and cannot be well applied to the complex pipeline layout of the hospital, making the renovation process difficult, time-consuming and labor-intensive. Summary of the invention

[0007] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is to transform the existing medical air-conditioning ducts to adapt to the complex pipeline layout scenarios of the hospital.

[0008] In order to solve the above problems, the present invention provides a zero-fire and spark-free electromechanical pipeline reconstruction process for existing medical buildings, including the following reconstruction processes: S1. Inspection: First, identify and locate the medical gas pipelines, drainage pipelines, electrical wire pipelines, fire protection pipelines and air conditioning pipelines to avoid mistakenly removing pipelines that do not need to be modified. Then, check along the pipeline lines and mark the positions that need to be replaced with a marker. When inspecting the air conditioning pipeline lines, if corroded or damaged air conditioning pipelines are found, cross the corroded or damaged positions with a marker to indicate that the air conditioning pipelines here need to be replaced. S2. Preparation before removal: prepare tools for removing wires, water supply pipes, and gas supply pipes. Before removing the water supply pipe, first close the water inlet valve, then drain the water in the pipe, and cut the pipe with a spark-free metal cutter. The same method is used for the gas supply pipe. First close the air inlet valve, drain the gas, and then cut the pipe with a spark-free metal cutter. Before removing the wires, first turn off the power, then use wire pliers to cut off the wire segments to be removed, and wrap the remaining exposed parts of the wires with insulating tape to seal them. When removing the air-conditioning pipes, first turn off the indoor and outdoor units of the air-conditioning, and check whether there is any refrigerant leakage after turning off the power. If there is, recycle the refrigerant first, and check whether the installation screws are loose. If so, tighten the installation screws; S3. Dismantling: After dismantling various pipelines with spark-free tools, those that need to be replaced should be replaced immediately, and the sealing work should be done well to avoid leakage. For overall dismantling, garbage cleaning work should be done well. When dismantling air-conditioning pipes, prepare electric hydraulic pliers and use them to cut on the marked pipes. When cutting, extend the mark to the left and right sides to 20-50 cm each. If the connection point between the pipes is within the extension range, the connection point is the cutting position; S4. Replacement: When replacing wires and pipelines, ensure that the neutral and live wires are correctly wired, then use quick-install pipe connectors to connect the wires, and do a good job of insulation and sealing. For the transformation of multiple electrical equipment, use splitters and connectors to connect them at appropriate locations. When replacing water and gas supply pipelines, ensure that the joints are well sealed to avoid leakage. When replacing air-conditioning pipelines, clip the quick-install pipelines onto the incisions of the pipelines. Before installing the quick-install pipelines, wrap the incisions with waterproof tape, and then clip the two ends of the quick-install pipeline onto the incisions on both sides. During installation, adjust the bending direction of the quick-install pipeline according to the direction of the original air-conditioning pipeline; Among them, the quick-install pipe includes a freely adjustable pipe, and both ends of the freely adjustable pipe are fixedly connected with quick-connect pipe joints, the freely adjustable pipe includes multiple fixed pipe bodies and curved pipe bodies, and the multiple fixed pipe bodies and curved pipe bodies are alternately connected, the quick-connect pipe joint includes an outer sleeve and an inner sleeve, and a connecting slot is opened between the outer sleeve and the inner sleeve.

[0009] In the above-mentioned zero-fire and spark-free electromechanical pipeline renovation process for existing medical buildings, the existing air-conditioning ducts are first dismantled using electric tools, and then the original ducts are replaced using quick-install ducts, thereby ensuring that no sparks occur during the renovation process, and the quick-install ducts can adapt to complex pipeline layouts.

[0010] As a further improvement of the present application, expansion grooves are provided on both side walls of the fixed tube body, and an expansion tube fixedly connected to the bent tube body is fixedly connected in the expansion groove. The expansion tube serves as a medium connecting the fixed tube body and the bent tube body, and plays a role of expansion and contraction adjustment, so that it can adapt to the adjustment of the bent tube body when it is bent. After cutting the original pipeline, it is difficult to ensure that the length between the two incisions is exactly equal to the length of the quick-install pipeline. Therefore, the expansion tube can compensate for the length deficiency of the quick-install pipeline, which is convenient for rapid transformation of the original air-conditioning pipeline.

[0011] As a further improvement of the present application, the telescopic tube includes an outer flexible wrapping layer and an inner elastic layer, and the flexible wrapping layer is made of a temperature-insulating and waterproof material. The telescopic tube is in a folded state when it is not extended. At this time, the telescopic tube is retracted in the telescopic groove on the fixed tube body. When the quick-install pipe is stretched, the telescopic tube is unfolded, thereby realizing the telescopic adjustment of the quick-install pipe. During the telescopic adjustment of the telescopic tube, the elastic layer plays a major role in the telescopic adjustment.

[0012] As a further improvement of the present application, the curved tube body includes an elastic tube sleeve, and an annular cavity is opened on the middle inner wall of the elastic tube sleeve, and the inner walls of the elastic tube sleeve on both sides of the annular cavity are fixedly inlaid with multiple randomly bent strips distributed at equal intervals, and multiple groups of parallel solid balls are placed inside the annular cavity, and each group of multiple solid balls are interconnected by elastic restraining belts, and both ends of each group of solid balls are fixedly connected to the inner wall of the annular cavity by elastic restraining belts at the same time, so that the curved tube body plays a bending role, so that when the original air-conditioning duct is modified, the newly installed quick-install duct can be adaptively bent up, down, left and right according to the direction of the pipeline, thereby effectively improving the adaptability of the quick-install duct, and when bending, the randomly bent strip plays a role of random bending, and in addition, in the process of bending of the curved tube body, multiple solid balls can adaptively move away from or close to each other according to the bending direction, and there are elastic restraining belts between the multiple solid balls for restraint, so that the mutual distance and approach of the solid balls can be restricted, thereby effectively preventing the curved tube body from excessive bending.

[0013] As a further improvement and supplement to the present application, the inner wall of the annular cavity is also fixedly connected to a plurality of rubber buffer contact pads fixedly connected to the elastic restraining band, and each rubber buffer contact pad is placed between two adjacent solid balls. When the plurality of solid balls approach each other, the two adjacent solid balls both rest on the rubber buffer contact pad. The rubber buffer contact pad can limit the further approach of the two adjacent solid balls, thereby effectively preventing the bent tube body from excessive bending.

[0014] As another improvement of the present application, the outer sleeve includes an outer shaping layer and an inner sealing clamping layer, and an elastic layer is filled between the outer shaping layer and the inner sealing clamping layer. When the quick-install pipe is clamped on the incision of the original pipe, the incision is inserted into the connecting slot, and the outer sleeve and the inner sleeve clamp the incision by clamping force. When clamping, the elastic layer relies on elastic force to make the inner sealing clamping layer fit tightly with the pipe incision, thereby achieving self-sealing.

[0015] As another improvement supplement to the present application, the outer sleeve and the inner sleeve have the same composition structure, and the arrangement direction of the composition structure is opposite. This is to allow the outer sleeve and the inner sleeve to clamp the original pipe, eliminating the trouble of drilling holes and installing screws. The outer sleeve and the inner sleeve cooperate to seal the cut of the pipe.

[0016] In summary, the transformation of existing medical air-conditioning pipelines through electric tools and quick-install pipes can effectively avoid the occurrence of sparks during the removal and installation process, thereby effectively improving the safety of construction. Quick-install pipes are used to replace the cut-off parts of the original pipelines. The quick-install pipes are connected to the original pipelines by snap-on connection, which saves the trouble of installation and can achieve self-sealing. In addition, the quick-install pipes can be bent up, down, left and right, so that they can adapt to the installation environment in the complex pipeline layout of the hospital. At the same time, the quick-install pipes also have the function of preventing excessive bending, which can effectively avoid pipeline rupture due to excessive bending.

DETAILED DESCRIPTION

[0019] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0020] The first implementation method: Figure 1 , 2 , 3 and Figure 4 The following transformation processes are shown: S1. Inspection: First, identify and locate the medical gas pipelines, drainage pipelines, electrical wire pipelines, fire protection pipelines and air conditioning pipelines to avoid mistakenly removing pipelines that do not need to be modified. Then, check along the pipeline lines and mark the positions that need to be replaced with a marker. When inspecting the air conditioning pipeline lines, if corroded or damaged air conditioning pipelines are found, cross the corroded or damaged positions with a marker to indicate that the air conditioning pipelines here need to be replaced. S2. Preparation before removal: prepare tools for removing wires, water supply pipes, and gas supply pipes. Before removing the water supply pipe, first close the water inlet valve, then drain the water in the pipe, and cut the pipe with a spark-free metal cutter. The same method is used for the gas supply pipe. First close the air inlet valve, drain the gas, and then cut the pipe with a spark-free metal cutter. Before removing the wires, first turn off the power, then use wire pliers to cut off the wire segments to be removed, and wrap the remaining exposed parts of the wires with insulating tape to seal them. When removing the air-conditioning pipes, first turn off the indoor and outdoor units of the air-conditioning, and check whether there is any refrigerant leakage after turning off the power. If there is, recycle the refrigerant first, and check whether the installation screws are loose. If so, tighten the installation screws; S3. Dismantling: After dismantling various pipelines with spark-free tools, those that need to be replaced should be replaced immediately, and the sealing work should be done well to avoid leakage. For overall dismantling, garbage cleaning work should be done well. When dismantling air-conditioning pipes, prepare electric hydraulic pliers and use them to cut on the marked pipes. When cutting, extend the mark to the left and right sides to 20-50 cm each. If the connection point between the pipes is within the extension range, the connection point is the cutting position; S4. Replacement: When replacing wires and pipelines, ensure that the neutral and live wires are correctly wired, then use quick-install pipe connectors to connect the wires, and do a good job of insulation and sealing. For the transformation of multiple electrical equipment, use splitters and connectors to connect them at appropriate locations. When replacing water and gas supply pipelines, ensure that the joints are well sealed to avoid leakage. When replacing air-conditioning pipelines, clip the quick-install pipelines onto the incisions of the pipelines. Before installing the quick-install pipelines, wrap the incisions with waterproof tape, and then clip the two ends of the quick-install pipeline onto the incisions on both sides. During installation, adjust the bending direction of the quick-install pipeline according to the direction of the original air-conditioning pipeline; Figure 5 , 6 and Figure 7As shown, the quick-install pipe includes a free-adjustable pipe 1, and both ends of the free-adjustable pipe 1 are fixedly connected with a quick-connect pipe head 2, the free-adjustable pipe 1 includes a plurality of fixed pipe bodies 101 and a curved pipe body 102, and the plurality of fixed pipe bodies 101 and the curved pipe body 102 are alternately connected, the quick-connect pipe head 2 includes an outer sleeve 201 and an inner sleeve 202, and a connecting slot 3 is provided between the outer sleeve 201 and the inner sleeve 202, the outer sleeve 201 includes an outer shaping layer 2011 and an inner sealing clamping layer 2012, and an elastic layer 2013 is filled between the outer shaping layer 2011 and the inner sealing clamping layer 2012, when When the quick-install pipe clamp is connected to the cutout of the original pipe, the cutout is inserted into the connecting slot 3, and the outer sleeve 201 and the inner sleeve 202 clamp the cutout by the clamping force. When clamping, the elastic layer 2013 makes the inner sealing clamping layer 2012 fit tightly with the cutout of the pipe by the elastic force, thereby achieving self-sealing. The outer sleeve 201 and the inner sleeve 202 have the same composition structure, and the arrangement direction of the composition structure is opposite. This is to allow the outer sleeve 201 and the inner sleeve 202 to clamp the original pipe, eliminating the trouble of drilling holes and installing screws. The outer sleeve 201 and the inner sleeve 202 cooperate to seal the cutout of the pipe; Figure 8 , 9 As shown, both side walls of the fixed tube body 101 are provided with expansion grooves, and the expansion grooves are fixedly connected with expansion tubes 4 fixedly connected to the curved tube body 102. The expansion tube 4 serves as a medium connecting the fixed tube body 101 and the curved tube body 102, and plays a role of expansion and contraction adjustment, so that it can adapt to the adjustment of the curved tube body 102 when it is bent. Moreover, after cutting the original pipeline, it is difficult to ensure that the length between the two incisions is exactly equal to the length of the quick-install pipeline. Therefore, the expansion tube 4 can compensate for the length deficiency of the quick-install pipeline, which is convenient for rapid transformation of the original air-conditioning pipeline. The expansion tube 4 includes an external flexible wrapping layer and an internal elastic layer (preferably a polyurethane elastic material, and other materials can also be selected according to actual needs), and the flexible wrapping layer is made of a thermal insulation and waterproof material. The expansion tube 4 is in a folded state when it is not extended. At this time, the expansion tube 4 is retracted in the expansion groove on the fixed tube body 101, and when the quick-install pipeline is stretched, the expansion tube 4 is unfolded, thereby realizing the expansion and contraction adjustment of the quick-install pipeline. In the process of expansion and contraction of the expansion tube 4, the elastic layer plays a major expansion and contraction adjustment role.

[0021] The second implementation method: Fig.10As shown, the bending tube body 102 includes an elastic tube sleeve 5, and an annular cavity 501 is opened on the inner wall of the middle part of the elastic tube sleeve 5. The inner wall of the annular cavity 501 is also fixedly connected with a plurality of rubber buffer pads 9 fixedly connected to the elastic restraining belt 8, and each rubber buffer pad 9 is placed between two adjacent solid balls 7. When the plurality of solid balls 7 approach each other, the two adjacent solid balls 7 both abut against the rubber buffer pad 9. The rubber buffer pad 9 can limit the further approach of the two adjacent solid balls 7, thereby effectively preventing the bending tube body 102 from being excessively bent. The inner walls of the elastic tube sleeve 5 on both sides of the annular cavity 501 are fixedly inlaid with a plurality of evenly spaced random bending strips 6 (preferably made of aluminum alloy, and other materials can also be selected according to actual needs). A plurality of groups of parallel bending strips 6 are placed inside the annular cavity 501. Solid balls 7, and each group of multiple solid balls 7 are interconnected with elastic restraining belts 8, and both ends of each group of solid balls 7 are fixedly connected to the inner wall of the annular cavity 501 through the elastic restraining belts 8, and the curved tube body 102 plays a bending role. In this way, when the original air-conditioning duct is modified, the newly installed quick-install duct can be adaptively bent up, down, left and right according to the direction of the pipeline, thereby effectively improving the adaptive ability of the quick-install duct. When bending, the random bending strip 6 plays a random bending role. In addition, in the process of bending the curved tube body 102, the multiple solid balls 7 can adaptively move away from or close to each other according to the bending direction, and the multiple solid balls 7 are restrained by elastic restraining belts 8, so the mutual distance and approach of the solid balls 7 can be limited, thereby effectively preventing the curved tube body 102 from excessive bending.

[0022] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
