Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0045] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediary, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0046] like Figures 1 to 5 As shown, a mobile swimming pool water-free detection device comprises a vacuum box (1) with openings at both ends and a gate (2) for closing the openings, wherein the gate (2) is arranged on one side of the opening and is electrically connected to a lifting member;

[0047] A plurality of sliding members (3) and lifting members (4) are provided at the bottom end of the vacuum box (1), wherein the sliding members (3) are arranged along the length direction of the vacuum box (1), and the lifting members (4) are interspersed between the sliding members (3);

[0048] The inner top surface of the vacuum box (1) is a plane;

[0049] The top of the vacuum box (1) is provided with a plurality of inflation valves (5) communicating with the interior of the hollow box;

[0050] The inflation valve (5) is connected to an inflation device;

[0051] Several air flow meters are installed in the vacuum box (1).

[0052] In order to solve the problem that the mobile swimming pool is heavy and inconvenient to move and flip, a vacuum box (1) is provided in the present invention, and the vacuum box (1) is adjacent to the transportation device of the assembly line. When detecting the leakage problem of the mobile swimming pool, the water can be transported to the vacuum box (1) through the transportation device of the assembly line. At this time, the gate of the vacuum box (1) is opened, so that the mobile swimming pool is transported to the sliding member (3) in the vacuum box (1). By driving the sliding member (3), the entire mobile swimming pool is transported to the vacuum box (1). At this time, the gate is closed, so that the empty box is in a sealed state. Then, the lifting member (4) is started, and the lifting member (4) lifts the mobile swimming pool to contact the inner top surface of the vacuum box (1). At this time, the mobile swimming pool and the vacuum box (1) form a sealed state. It is worth mentioning that when the lifting member (4) is not lifted, the horizontal height of its top surface is lower than the horizontal height of the top surface of the sliding member (3) to ensure that the mobile swimming pool can move on the sliding member (3). When the operation of the lifting member (4) is completed, the external inflation device is started and the inflation valve (5) located just above the mobile swimming pool is opened to input gas into the mobile swimming pool. Since the cylinder of the mobile swimming pool and the inner top surface of the vacuum box (1) are in a sealed state at this time, and the interior of the vacuum box (1) is also in a sealed state, the air flow rate in the vacuum box (1) is relatively fixed because it is not affected by the outside world. If there is a gap in the mobile swimming pool, the gas filled in the mobile swimming pool will flow into the vacuum box (1) through the gap. Since the gas is continuously input into the mobile swimming pool, the gas flowing into the vacuum box (1) will form a stable output airflow, thereby causing the change of the gas flow rate in the vacuum box (1). By arranging an air flow meter in the vacuum box (1) to detect the airflow in the vacuum box (1), and judging whether the change of the airflow is greater than a threshold value, it can be judged whether the mobile swimming pool has a water leakage problem.

[0053] In the present application, the mobile swimming pool is transported and its height position is adjusted by means of a sliding member (3) and a lifting member (4), and the air tightness of the mobile swimming pool is tested by means of gas input. During the test, there is no need to fill the mobile swimming pool with water or flip it over, which reduces the speed and difficulty of testing a heavy mobile swimming pool.

[0054] In addition, since the vacuum box (1) is in a sealed state, in order to effectively observe the operating state, an observation window covered with transparent glass can be opened on the vacuum box (1) to detect the internal operating conditions through the observation window.

[0055] Preferably, the sliding members (3) are provided in two groups, and are respectively provided on both sides of the bottom end of the vacuum box (1);

[0056] The sliding member (3) comprises a long sprocket bracket (3a) and a plurality of mounting brackets (3b), wherein the long sprocket bracket (3a) is arranged along the length direction of the vacuum box (1), and the plurality of mounting brackets (3b) are arranged opposite to the long sprocket bracket (3a), and a plurality of rollers (3c) are hinged between the mounting bracket (3b) and the long sprocket bracket (3a), and the rollers of the plurality of rollers are hinged to the hinge in the long sprocket bracket (3a).

[0057] In the present invention, the sliding member (3) is provided on both sides of the vacuum box (1), and the sliding member (3) includes a sprocket long bracket (3a) and a plurality of mounting brackets (3b). The rollers of the plurality of rollers (3c) can be connected by hinges in the sprocket long bracket (3a), so that the plurality of rollers (3c) can move simultaneously to transport the mobile pool. At the same time, the link can be connected by a motor to drive the operation of the sprocket. In addition, the present invention does not use a whole roller (3c) to transport the mobile pool, but uses two sliding members (3) to transport the mobile pool. This is because the weight of the mobile pool is relatively larger than that of other mobile pools. If the whole roller (3c) is used to transport it, the rotational inertia of the roller (3c) will increase when starting the roller (3c). If the roller (3c) is driven for transportation, a more powerful motor is required as the power output of the roller (3c). However, a high-power motor will generate violent vibrations when in standby mode, thereby affecting the air flow meter's detection of the air flow rate. Therefore, by providing two separate slides (3) to transport the mobile swimming pool, the lever arm of the roller (3c) can be shortened, so that a motor with a smaller power can be used to transport the mobile swimming pool without affecting the operation of the air flow meter.

[0058] Preferably, the lifting member (4) comprises a plurality of lifting rods (4a), two mounting rods (4b), a plurality of power connecting rods (4c) and a power device (4d);

[0059] Two mounting rods (4b) are respectively arranged between the two groups of sliding members (3); a plurality of lifting rods (4a) are arranged between the two mounting rods (4b); and the lifting rods (4a) and the rollers (3c) are interlaced.

[0060] The power connecting rod (4c) is fixedly connected to the installation rod (4b) and the power device (4d) respectively, and the power connecting rod (4c) is provided with a screw hole;

[0061] The power device (4d) comprises a jacking machine (4da) and a screw rod (4db); the output end of the jacking machine (4da) faces upward and is equipped with a screw rod (4db); the screw rod (4db) is inserted into a screw hole of the power connecting rod (4c);

[0062] The plurality of jacking machines (4da) are connected via a synchronization rod;

[0063] When the lifting member (4) is in a non-lifted state, the horizontal height of the lifting rod (4a) is lower than the height of the roller (3c).

[0064] In the present invention, a power device (4d) drives a screw rod (4db) to rotate, and a screw hole is provided on the power connecting rod (4c). The screw hole cooperates with the screw rod (4db) to lift a lifting rod (4a) connected to the mounting rod (4b), thereby realizing the lifting function of the mobile swimming pool.

[0065] Preferably, the power connecting rod (4c) comprises 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 a 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);

[0066] The third rod (4cc) is provided with a screw hole;

[0067] A reinforcement member (4cd) is installed between the first rod body (4ca) and the mounting rod (4b), and between the second rod body (4cb) and the third rod body (4cc).

[0068] The power connecting rod (4c) as a screw rod (4db) needs to withstand the gravity of the mobile swimming pool to transmit power. If the power connecting rod (4c) is only a one-piece rod body, when bearing the gravity of the mobile swimming pool, the bending moment borne by the power connecting rod (4c) will increase with the length of the rod body. The increased bending moment is more likely to cause the power connecting rod (4c) to break. In order to be able to lift a heavy mobile swimming pool, in this application, the power connecting rod (4c) is formed by combining a first rod body (4ca), a second rod body (4cb) and a third rod body (4cc). By shortening the length of the rod body to reduce the bending moment, the service life of the power connecting rod (4c) and its supporting capacity are increased. The first rod (4ca) is located above the sprocket long bracket (3a), and the second rod (4cb) is arranged vertically downward to increase the horizontal height of the first rod (4ca) when stationary, thereby preventing the first rod (4ca) from pressing on the sprocket long bracket (3a) in a non-elevated state, thereby causing damage to the sprocket long bracket (3a). At the same time, a reinforcement member (4cd) is installed between the first rod (4ca) and the mounting rod (4b), and between the second rod (4cb) and the third rod (4cc), to increase the overall structural stability of the power connecting rod (4c), thereby providing the supporting capacity of the power connecting rod (4c), so as to be suitable for lifting a heavy mobile swimming pool.

[0069] Preferably, it further comprises a PE wear-resistant strip (6), wherein the PE wear-resistant strip (6) is arranged along the length direction of the mounting rod (4b), and the PE wear-resistant strip (6) is arranged on a side facing the inside of the vacuum box (1).

[0070] The mobile swimming pool may not be placed in a good position before entering the vacuum box (1), and may collide with the installation rod (4b) when entering the vacuum box (1). Therefore, a PE wear-resistant strip (6) is also provided in the present invention. The PE wear-resistant strip (6) covers one side of the installation rod (4b) to reduce the friction of the installation rod (4b) on the mobile swimming pool, thereby ensuring the product quality of the mobile swimming pool.

[0071] Preferably, it further comprises a filling air bag (7), wherein the filling air bag (7) is arranged on the inner top surface of the vacuum box (1), and the filling air bag (7) is connected to the inflation valve (5).

[0072] The filling air bag (7) is always in an inflated state. When testing, the mobile swimming pool is transported to the bottom of the filling air bag (7), and then the lifting member (4) is activated, so that the filling air bag (7) is placed in the cylinder of the mobile swimming pool, reducing the inner cavity volume of the cylinder of the mobile swimming pool. When testing the air tightness of the mobile swimming pool, the input amount of gas into the cylinder of the mobile swimming pool can be reduced, thereby accelerating the efficiency of the test.

[0073] Preferably, it further comprises a first sealing airbag (8), wherein the first sealing airbag (8) covers the inner top surface of the vacuum box (1), and the first sealing airbag (8) is connected to the inflation valve (5).

[0074] In the invention, in order to increase the effectiveness of the detection, the inner top surface of the vacuum box (1) is covered with a first sealing airbag (8). In the non-operating state, the first sealing airbag (8) is not filled with gas. When the mobile swimming pool is lifted to the inner top surface of the vacuum box (1), the mobile swimming pool contacts the first sealing airbag (8). At this time, the inflation valve (5) connected to the first sealing airbag (8) is opened, and gas is filled into the first sealing airbag (8). The first sealing airbag (8) expands to seal the gap between the mobile swimming pool and the inner top surface of the vacuum box (1). This prevents the gas filled in the mobile swimming pool from flowing out of the gap between the mobile swimming pool and the inner top surface of the vacuum box (1), causing a misjudgment of the detection.

[0075] Preferably, it further comprises a second sealing airbag (9), wherein the second sealing airbag (9) is arranged around the openings at both ends of the vacuum box (1).

[0076] In the invention, in order to increase the effectiveness of the detection, a second sealing airbag (9) is provided at the opening of the vacuum box (1). In a non-operating state, the second sealing airbag (9) is not filled with gas. When the gate (2) falls, the second sealing airbag (9) is inflated. The second sealing airbag (9) expands to fill the gap between the gate (2) and the opening, so as to prevent the gas outside the vacuum box (1) from flowing into the vacuum box (1) and causing misjudgment of the detection.

[0077] A mobile swimming pool water-free detection method, using the mobile swimming pool water-free detection device, comprises the following steps:

[0078] Step S1: transporting the mobile swimming pool to the sliding member (3) in the vacuum box (1), and transporting the mobile swimming pool to below the detection station in the vacuum box (1) via the sliding member (3);

[0079] Step S2: closing the gate (2) so that the interior of the vacuum box (1) is in a sealed state;

[0080] Step S3: activating the lifting member (4), and lifting the mobile swimming pool by means of the lifting member (4) until the cylinder mouth of the mobile swimming pool contacts the inner top wall of the vacuum box (1), so that the mobile swimming pool is sealed and filled;

[0081] Step S4: starting the inflation device and opening the inflation valve (5) located above the mobile swimming pool;

[0082] Step S5: Detecting whether the change in the air flow rate between the vacuum box (1) and the mobile swimming pool is greater than a threshold value. If so, it indicates that the mobile swimming pool has a water leakage problem;

[0083] Step S6: activating the lifting member (4) again to lift the mobile swimming pool so that the mobile swimming pool contacts the sliding member (3);

[0084] The gate is opened, and the mobile swimming pool after inspection is moved out of the vacuum box (1).
