Description

Technical Field

[0001] This invention relates to the field of cylinder testing technology, and in particular to a mobile swimming pool waterless testing device and waterless testing method with a single airbag sealing structure. Background Technology

[0002] In recent years, with the improvement of people's living standards, bathtubs that combine bathing and fitness have developed rapidly. Many private residences or high-end hotels have bathtubs. They stimulate various parts of the human body by spraying water through multiple nozzles distributed in the tub, which can massage muscles, accelerate blood circulation, relieve pain and improve joint mobility.

[0003] In industry, to improve product quality and meet people's needs, bathtubs typically undergo a series of drainage and leakage tests before leaving the factory. Currently, leakage testing involves filling the bathtub with liquid and observing the outer surface for water droplets. If water droplets are present, it indicates a leakage problem. After the test, a tilting mechanism is used to tilt the bathtub and empty the water.

[0004] However, existing leak detection methods have the following problems when operating mobile pools: 1. When checking for water droplets on the outside of the mobile pool, it is necessary to walk around the mobile pool to check, and the mobile pool is relatively large, which also increases the detection time.

[0005] 2. The mobile pool is large in size, requiring a large amount of water to be filled, which increases the testing time. In addition, the water needs to be emptied after the test, and the mobile pool is heavy after filling, requiring an additional tipping mechanism to tilt it stably and ensure the safety of the pool, which greatly increases the cost of mobile pool testing. Summary of the Invention

[0006] To address the aforementioned shortcomings, the present invention aims to provide a waterless mobile swimming pool testing device with a single airbag sealing structure, thereby accelerating the testing speed of mobile swimming pools and reducing the testing difficulty.

[0007] To achieve this objective, the present invention adopts the following technical solution: a mobile swimming pool waterless detection device with a single airbag sealing structure, comprising a lifting component and a sealing top cover;

[0008] The lifting component is located directly below the sealing top cover;

[0009] The lower surface of the sealing top cover is covered with a sealing airbag, and the sealing airbag is provided with a missing part;

[0010] The upper surface of the sealed top cover is provided with several inflation valves, which are connected to an inflation device.

[0011] The inflation valve is connected to the sealing airbag, and at least one inflation valve is located directly above the missing part.

[0012] The lifting component is used to drive the mobile swimming pool to move up and down.

[0013] Preferably, the lifting component includes a plurality of lifting rods, two mounting rods, a plurality of power connecting rods, and a power device;

[0014] Two mounting rods are respectively set opposite each other, and the two ends of several lifting rods are respectively fixed between the two mounting rods;

[0016] The power unit includes a lifting machine and a lead screw. The output end of the lifting machine faces upward and is equipped with a lead screw, which is inserted into the screw hole of the power connecting rod.

[0017] Preferably, the power connection rod includes a first rod body, a second rod body, and a third rod body; one end of the first rod body is horizontally fixed to the side of the mounting rod opposite to the lifting rod, one end of the second rod body is vertically connected downward to the other end of the first rod body, the sprocket long bracket is located between the second rod body and the lifting rod, and one end of the third rod body is horizontally fixed to the other end of the second rod body;

[0018] The third rod body is provided with a screw hole;

[0019] Reinforcing members are installed between the first rod and the second rod, and between the second rod and the third rod.

[0020] Preferably, it also includes PE wear-resistant strips, which are arranged along the length of the mounting rod and are respectively arranged on the opposite sides of the two mounting rods.

[0021] Preferably, it also includes two sets of sliding member groups, which are respectively interposed in the lifting member, and each sliding member group includes a plurality of sliding members;

[0022] The sliding component includes a sprocket long bracket and several mounting brackets. The sprocket long bracket is disposed on the outside of the mounting rod, the mounting bracket is disposed between two mounting rods, and a roller is installed between the sprocket long bracket and the mounting bracket.

[0023] The roller and the lifting rod are interlocked;

[0024] When the lifting member is in an unlifted state, the horizontal height of the lifting rod is lower than the height of the roller.

[0025] Preferably, it further includes a filling airbag, which is disposed below the sealing airbag or below the missing portion, and the filling airbag is connected to the inflation valve.

[0026] Preferably, a plurality of the locking elements are distributed on the outer side of the lifting element;

[0027] The locking component includes a mounting post, a mounting base, a cylinder, and a locking block;

[0028] The mounting base is fixedly installed on the top of the mounting column. The mounting base has a hinge part. The locking block is hinged to the hinge part. The cylinder is installed on the side of the mounting base away from the lifting member. The output end of the cylinder is connected to one end of the locking block. The top of the mounting base has a notch. When the cylinder is not in working state, the locking block is entirely located inside the mounting base.

[0029] The cylinder is driven to extend, and the locking block rotates about the hinge, with the other end of the locking block protruding from the notch.

[0030] A method for detecting waterless operation of a mobile swimming pool with a single-airbag sealing structure, using the aforementioned waterless operation detection device for a mobile swimming pool with a single-airbag sealing structure, includes the following steps:

[0031] Step 1: Move the mobile pool to the lifting component, with the opening of the mobile pool's tank located below the missing part;

[0032] Step 2: Activate the lifting device to raise the mobile pool until the opening of the mobile pool's tank comes into contact with the sealing airbag;

[0033] Step 3: Start the inflation device and open the inflation valve connected to the sealing airbag to inflate the sealing airbag until it is fully inflated, then close the inflation valve connected to the sealing airbag.

[0034] Step 4: Open the air valve located above the missing part, and the gas enters the tank of the mobile pool through the air valve;

[0035] Step 5: Workers use an airflow detection device to inspect the outside of the mobile pool. If an area is found where the gas flow rate changes more than the threshold, it is determined that there is a leak in that area of ​​the mobile pool.

[0036] One of the above technical solutions has the following advantages or beneficial effects: 1. The gas delivery speed is controllable, and the delivery speed is much faster than the water flow rate before the test, which can speed up the testing process. Furthermore, the sealing airbag is inflated after the mobile pool comes into contact with it, effectively sealing the mobile pool tank and making its interior sealed. The portion of the sealing airbag located inside the mobile pool tank expands when inflated, thereby reducing the internal volume of the mobile pool and accelerating the testing process.

[0037] 2. Compared to existing technologies that require emptying water after water detection, gas detection allows for direct descent of the lifting component after detection, eliminating the need for subsequent processing and reducing the difficulty of post-detection operations.

[0047] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0048] like Figures 1-5 As shown, a mobile swimming pool waterless detection device with a single airbag sealing structure includes a lifting component (4) and a sealing top cover (1).

[0049] The lifting component (4) is located directly below the sealing top cover (1);

[0050] The lower surface of the sealing top cover (1) is covered with a sealing airbag (2), and the sealing airbag (2) is provided with a missing part (2a).

[0051] The upper surface of the sealed top cover (1) is provided with several inflation valves (5), and the inflation valves (5) are connected to the inflation device.

[0052] The inflation valve (5) is connected to the sealing airbag (2), and at least one inflation valve (5) is located directly above the missing part (2a);

[0053] The lifting component (4) is used to drive the mobile swimming pool to move up and down.

[0054] To address the issues of long testing times and cumbersome post-testing processing in existing mobile swimming pools, this invention includes a lifting component (4), a sealing top cover (1), and an inflation valve (5). During testing, the mobile swimming pool is moved to the lifting component (4), with the pool's cylinder opening positioned below the missing portion (2a). The lifting component (4) is then activated to lift the pool until the cylinder opening contacts the sealing airbag (2). The inflation device is then activated, and the inflation valve (5) connected to the sealing airbag (2) is opened to inflate it until it is fully inflated. The inflation valve (5) is then closed. As the sealing airbag (2) expands due to being filled, it extends downwards to seal the gap between the mobile swimming pool and the sealing top cover (1), thus maintaining a sealed state within the pool's cylinder. The sealing airbag (2) is provided with a missing part (2a). The missing part (2a) does not have an airbag structure. The gas through the inflation valve (5) can directly enter the cylinder of the mobile pool through the missing part (2a) to continuously supply gas to the mobile pool. If a gap appears in the mobile pool, the gas will flow out of the mobile pool cylinder from the gap. The inspector only needs to hold an air flow rate detection device outside the mobile pool cylinder. Since there is also air flow outside the cylinder, as long as the change value of the detection device is greater than a certain threshold, it can be immediately determined that the mobile pool cylinder has a gas leakage problem, that is, the mobile pool has a crack.

[0055] The gas detection method has the following advantages: 1. The gas delivery speed is controllable, and the delivery speed is much faster than the water flow rate before the test, which can speed up the detection. In addition, the sealing airbag (2) is inflated after the mobile pool comes into contact with it, which can effectively seal the mobile pool tank and make its interior sealed. The part of the sealing airbag (2) located inside the mobile pool tank can expand when it is inflated, thereby reducing the internal volume of the mobile pool and speeding up the detection.

[0056] 2. Compared with the existing technology that requires emptying water after water detection, gas detection allows the lifting component (4) to be driven down directly after detection, eliminating the need for subsequent processing and reducing the difficulty of operation after detection.

[0057] Preferably, the lifting member (4) includes a plurality of lifting rods (4a), two mounting rods (4b), a plurality of power connecting rods (4c), and a power unit (4d).

[0058] Two mounting rods (4b) are respectively set opposite each other, and the two ends of a plurality of lifting rods (4a) are respectively fixed between the two mounting rods (4b);

[0059] The power connecting rod (4c) is fixedly connected to the mounting rod (4b) and the power device (4d) respectively, and the power connecting rod (4c) is provided with screw holes;

[0060] The power unit (4d) includes a lifting machine (4da) and a lead screw (4db). The output end of the lifting machine (4da) faces upward and is equipped with the lead screw (4db). The lead screw (4db) is inserted into the screw hole of the power connecting rod (4c).

[0061] The mobile swimming pool is placed on the lifting rod (4a). In this invention, a power device (4d) drives the lead screw (4db) to rotate. The power connecting rod (4c) is provided with a screw hole. Through the cooperation of the screw hole and the lead screw (4db), the power connecting rod (4c) moves up and down in conjunction with the lead screw (4db). The power connecting rod (4c) is connected to the mounting rod (4b), and the lifting rod (4a) connected to the mounting rod (4b) will also be raised or lowered. This achieves the function of lifting the mobile swimming pool.

[0062] Preferably, the power connecting rod (4c) includes a first rod body (4ca), a second rod body (4cb), and a third rod body (4cc); one end of the first rod body (4ca) is horizontally fixed to the side of the mounting rod (4b) facing away from the lifting rod (4a), one end of the second rod body (4cb) is vertically connected downward to the other end of the first rod body (4ca), the sprocket long bracket (3a) is located between the second rod body (4cb) and the lifting rod (4a), and one end of the third rod body (4cc) is horizontally fixed to the other end of the second rod body (4cb);

[0063] The third rod (4cc) has a screw hole;

[0064] A reinforcing member (4cd) is installed between the first rod (4ca) and the second rod (4cb), and between the second rod (4cb) and the third rod (4cc).

[0065] The power connecting rod (4c), acting as a lead screw (4db), needs to withstand the weight of the moving pool. If the power connecting rod (4c) is a single, integrally formed rod, the bending moment it bears when supporting the weight of the moving pool will increase with the length of the rod. This increased bending moment makes the power connecting rod (4c) more prone to breakage. To lift the heavy moving pool, in this application, the power connecting rod (4c) is formed by combining a first rod (4ca), a second rod (4cb), and a third rod (4cc). By shortening the length of the rods to reduce the bending moment, the service life and load-bearing capacity of the power connecting rod (4c) are improved. The first rod (4ca) is located above the sprocket support (3a). A downwardly vertically positioned second rod (4cb) increases the horizontal height of the first rod (4ca) when stationary, preventing it from pressing against the sprocket support (3a) and causing damage when not in a raised state. Simultaneously, reinforcing members (4cd) are installed between the first rod (4ca) and the second rod (4cb), and between the second rod (4cb) and the third rod (4cc), increasing the overall structural stability of the power connecting rod (4c) and providing it with sufficient support for lifting heavy mobile swimming pools.

[0066] Preferably, it also includes PE wear-resistant strips (6), which are arranged along the length direction of the mounting rod (4b), and the PE wear-resistant strips (6) are respectively arranged on the opposite sides of the two mounting rods (4b).

[0067] Before entering the propulsion lifting member (4), the initial position of the mobile pool may be slightly biased towards one side of the lifting member (4). When moving inside the vacuum chamber (1), it may collide with the mounting rod (4b) of the lifting member (4). Therefore, in this invention, a PE wear-resistant strip (6) is also provided. The PE wear-resistant strip (6) covers one side of the mounting rod (4b) to reduce the friction between the mounting rod (4b) and the mobile pool, thus ensuring the product quality of the mobile pool.

[0068] Preferably, it also includes two sets of sliding member groups, which are respectively interspersed in the lifting member (4), and each sliding member group includes a plurality of sliding members (3).

[0069] The sliding member (3) includes a sprocket long bracket (3a) and a plurality of mounting brackets (3b). The sprocket long bracket (3a) is disposed on the outside of the mounting rod (4b), and the mounting brackets (3b) are disposed between the two mounting rods (4b). A roller (3c) is installed between the sprocket long bracket (3a) and the mounting brackets (3b).

[0070] The roller (3c) and the lifting rod are interlocked;

[0071] When the lifting member (4) is in an unlifted state, the horizontal height of the lifting rod (4a) is lower than the height of the roller (3c).

[0072] In this invention, two sets of sliding parts are provided. Each sliding part (3) includes a sprocket support (3a) and several mounting brackets (3b). The rollers of multiple rollers (3c) can be connected by hinges within the sprocket support (3a), allowing multiple rollers (3c) to move simultaneously to transport the mobile pool. Simultaneously, a motor can be used to drive the sprocket. Furthermore, this invention does not use a single roller (3c) to transport the mobile pool, but rather two sliding parts (3) because the mobile pool is relatively heavier than other bathtubs. If a single roller (3c) is used for transport, the rotational inertia when starting the roller (3c) will increase. To drive the roller (3c) for transport, a more powerful motor is needed as the power output for the roller (3c). A high-power motor will produce severe vibrations when idle, affecting the stability of the inspector while walking, which may affect the air velocity meter's detection of air velocity. Therefore, by setting two separate sliding parts (3) to transport the mobile pool, the lever arm of the roller (3c) can be shortened, so that the mobile pool can be transported using a smaller motor without affecting the operation of the air flow meter.

[0073] Preferably, it also includes a filling airbag (7), which is disposed below the sealing airbag (2) or below the missing part (2a), and the filling airbag (7) is connected to the inflation valve (5).

[0074] The filling airbag (7) is always inflated. The filling airbag (7) can be positioned below the sealing airbag (2) or at the missing part (2a). During testing, the mobile pool is transported to the area below the filling airbag (7), and then the lifting member (4) is activated, placing the filling airbag (7) inside the mobile pool's cylinder, thus reducing the internal volume of the mobile pool's cylinder. This reduces the amount of gas input into the mobile pool's cylinder during airtightness testing, improving testing efficiency.

[0075] Preferably, a plurality of the locking members (8) are distributed on the outside of the lifting member (4);

[0076] The locking component (8) includes a mounting post (8a), a mounting base (8b), a cylinder (8c), and a locking block (8d);

[0077] The mounting base (8b) is fixedly installed on the top of the mounting column (8a). The mounting base (8b) has a hinge part (8ba). The locking block (8d) is hinged to the hinge part (8ba). The cylinder (8c) is installed on the side of the mounting base (8b) away from the lifting member (4). The output end of the cylinder (8c) is connected to one end of the locking block (8d). The top of the mounting base (8b) has a notch (8e). When the cylinder (8c) is not working, the locking block (8d) is entirely located inside the mounting base (8b).

[0078] The cylinder (8c) is driven to extend, the locking block (8d) rotates about the hinge (8ba) as the pivot, and the other end of the locking block (8d) protrudes from the notch (8e).

[0079] A method for detecting waterless operation of a mobile swimming pool with a single-airbag sealing structure, using the aforementioned waterless operation detection device for a mobile swimming pool with a single-airbag sealing structure, includes the following steps:

[0080] Step 1: Move the mobile pool to the lifting member (4), with the opening of the mobile pool body located below the missing part (2a);

[0081] Step 2: Activate the lifting device (4) to lift the mobile pool until the opening of the mobile pool's cylinder comes into contact with the sealing airbag (2);

[0082] Step 3: Start the inflation device and open the inflation valve (5) connected to the sealing airbag (2) to inflate the sealing airbag (2) until the sealing airbag (2) is full of gas, and then close the inflation valve (5) connected to the sealing airbag (2).

[0083] Step 4: Open the inflation valve (5) located above the missing part (2a), and gas enters the tank of the mobile pool through the inflation valve (5);

[0084] Step 5: Workers use an airflow detection device to inspect the outside of the mobile pool. If an area is found where the gas flow rate changes more than the threshold, it is determined that there is a leak in that area of ​​the mobile pool.
