[0002] A liquid tank is a tank for storing liquids and can store liquefied natural gas. When transporting a liquid tank, it often needs to be assembled on a transport vehicle or transport ship. However, during the assembly process, the lifting equipment will cause damage to the transportation equipment and the liquid tank itself even if it descends slowly when lifting and installing the liquid tank. In addition, the stability of the transportation cannot be guaranteed during the transportation process, which will lead to certain hidden dangers in the transportation of the liquid tank. However, due to the large size of the liquid tank itself, it is impossible to detect the inside of the liquid tank during transportation. Even if the liquid tank leaks, the staff will not be able to immediately know the status of the liquid tank, which will lead to unnecessary losses. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. When using the device, the liquid tank must first be assembled to adapt to liquid tanks of different sizes and to absorb the impact force received by the liquid tank when it falls. During transportation, the water pressure and air pressure in the liquid tank can also be detected to ensure that the liquid tank will not leak during transportation.

[0017] 2.

In specific use, when the liquid tank is placed between the two sets of limit saddles through the lifting device, the liquid tank will first contact the piston rod, and the downward pressure of the liquid tank will force the piston rod to move downward, so that the piston rod will drive the rubber piston to move downward, so as to squeeze the air in the buffer tube, so that the air in the buffer tube can flow into the collecting tube and enter the rubber airbag from the collecting tube, thereby inflating the rubber airbag. When the liquid tank contacts the rubber airbag, the rubber airbag will buffer the liquid tank, thereby reducing the force exerted on the limit saddle and the liquid tank. After that, after the liquid tank slowly descends, the air in the rubber airbag will be discharged from the collecting tube along with the pressure of the liquid tank. When the liquid tank is removed, the return spring in the buffer tube will reset the piston rod for subsequent use.

[0018] 3. When the test component of the device is in use, it can detect the water pressure in the liquid tank. When using it, you first need to place the installation ball inside the liquid tank. The installation ball will move to the designated position with the water flow and be fixed in the designated position by magnetism. At this time, energy is transmitted through the magnetic field coupling between the transmitting coil and the receiving coil, so as to wirelessly charge the installation ball to ensure that the installation ball can be continuously used. During the movement of the installation ball, because the counterweight block is installed in the installation ball through the bearing, the counterweight ball will always be horizontally downward, ensuring that the support rod and multiple sets of pressure sensing plates can always face upward, and because the pressure sensing plate is close to the inner top of the installation ball, when the liquid presses the outer shell of the installation ball, the outer shell of the installation ball will be concave, which will squeeze the pressure sensing plate, thereby transmitting the value to the controller through the pressure sensing plate. Therefore, the installation ball of the device can test the water pressure during the transportation of the liquid tank. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example: Figures 1-8 As shown, the present invention provides a liquid tank water pressure test equipment with a self-stabilizing function, including a test equipment body 1 and a controller 8. The test equipment includes a support platform 11, on which a support saddle 2 and two sets of limit saddles 3 are installed. The two sets of limit saddles 3 are respectively installed at both ends of the liquid tank, and the support installation is located in the middle of the liquid tank. The support saddle 2 cooperates with the limit saddle 3. The liquid tank cooperates with the limit saddle 3 and the support saddle 2 respectively. An adjustment component 5 and a test component 4 are installed on the support saddle 2. The test component 4 needs to be placed in the liquid tank. The adjustment component 5 can adjust the distance between the limit saddle 3 and the support saddle 2;

[0030] When the device is in use, it is first necessary to adjust the distance between the supporting saddle 2 and the limiting saddle 3 according to the size of the liquid tank so as to adapt to liquid tanks of different sizes. At the same time, when the liquid tank is placed on the device from the crane, the buffer component 6 on the limiting saddle 3 will buffer the falling force of the liquid tank to prevent the instantaneous force from causing damage to the liquid tank or the device, thereby ensuring the safety of the device and the liquid tank. After the liquid tank is placed, the test component 4 needs to be placed inside the liquid tank, and then liquid is injected into the liquid tank. At this time, even if the test component 4 has not reached the specified position, it will be in the water. The liquid tank moves to the designated position under the impact of the flow. After the liquid tank is filled, the air pressure detection component 7 of the device needs to be installed at the water inlet and the water outlet respectively, so that when the liquid tank is transported, the changes in the internal water pressure and air pressure can be detected in real time to ensure that the liquid tank will not leak during transportation. Because the device fixes the liquid tank through the supporting saddle 2 and the two sets of limiting saddles 3, it can achieve a self-stabilizing effect on each liquid tank, and can detect the water pressure and air pressure in the liquid tank in real time, thereby ensuring the safety of the liquid tank during transportation.

[0031] like Figure 4 As shown, in this embodiment, specifically, the limiting saddle 3 includes a support block 31 and a limiting plate 32. The limiting plate 32 is installed on the support block 31. Two groups of buffer components 6 and multiple groups of support steel plates are installed between the support block 31 and the limiting plate 32. The buffer component 6 can buffer the force when the buffer tank is placed on the support saddle 2. A baffle is installed on the side of the limiting plate 32, and anti-slip strips are respectively provided on the baffle and the limiting plate 32.

[0032] When in use, the limiting saddle 3 of the device plays the main supporting force for the liquid tank, and when the liquid tank is placed on the limiting saddle 3, the falling force of the liquid tank can be buffered by the buffer component 6, thereby reducing the damage to the liquid tank and the device during use. During specific use, the staff needs to adjust the position of the limiting saddle 3 through the adjustment component 5 according to the size of the liquid tank so as to be able to adapt to liquid tanks of different sizes. When the liquid tank is then placed between the limiting saddles 3 through the lifting device, the slowly descending liquid tank will first contact the buffer component 6, thereby reducing the force exerted on the liquid tank and the device through the buffer component 6, and the anti-slip strips on the baffle and the limiting plate 32 can play an anti-slip role, so as to cooperate with the two sets of limiting saddles 3 to provide limiting support for the liquid tank.

[0033] like Figure 4 、 Figure 6 and Figure 8As shown, in this embodiment, specifically, the buffer assembly 6 includes a buffer tube 61 and a rubber airbag 62. A piston rod 63 is installed inside the buffer tube 61. The piston rod 63 is slidably installed inside the buffer tube 61. A rubber piston 64 is installed at one end of the piston rod 63 located inside the buffer tube 61. A return spring 65 is provided between the rubber piston 64 and the buffer tube 61. The other end of the piston rod 63 is located above the limit plate 32. The bottoms of the multiple groups of buffer tubes 61 are respectively connected to a collection pipe 66 through a conduit. The rubber airbag 62 is installed above the limit plate 32 and is connected to the collection pipe 66.

[0034] The buffer assembly 6 of the device will buffer the falling force of the liquid tank when in use, preventing the instantaneous force from causing damage to the liquid tank or the device, thereby ensuring the safety of the device and the liquid tank. In specific use, when the liquid tank is placed between the two sets of limit saddles 3 through the lifting device, the liquid tank will first contact the piston rod 63, and the downward pressure of the liquid tank will force the piston rod 63 to move downward, so that the piston rod 63 will drive the rubber piston 64 to move downward, so as to squeeze the air in the buffer tube 61, so that the air in the buffer tube 61 can flow to the collecting pipe 66 and enters the rubber airbag 62 from the collecting pipe 66, thereby inflating the rubber airbag 62. When the liquid tank contacts the rubber airbag 62, the rubber airbag 62 will cushion the liquid tank, thereby reducing the force exerted on the limit saddle 3 and the liquid tank. After that, after the liquid tank slowly descends, the air in the rubber airbag 62 will be discharged from the collecting pipe 66 along with the pressure of the liquid tank. When the liquid tank is removed, the return spring 65 in the buffer tube 61 will reset the piston rod 63 for subsequent use.

[0035] like Figure 2-Figure 3 As shown, in this embodiment, specifically, the supporting saddle 2 includes a load-bearing block 21, an adjustment component 5 is installed in the middle of the load-bearing block 21, and limit rods are installed on both sides of the bottom of the load-bearing block 21. A transmitting coil 22 is installed above the load-bearing block 21, and the transmitting coil 22 cooperates with the test component 4;

[0036] When in use, the support saddle 2 of the device can play the role of spreading the load, and the support saddle 2 can cooperate with the test component 4 to monitor the water pressure in the liquid tank in real time. During specific use, the liquid tank can be supported by the load-bearing block 21, and the pressure exerted on the two groups of support saddles 2 can be shared. During the test, the test component 4 needs to be placed inside the liquid tank. The test component 4 will cooperate with the transmitting coil 22 under the push of the water flow, so that it is confined to the bottom of the liquid tank, so that the test component 4 can be powered by the transmitting coil 22 to ensure that the test component 4 can always stay online.

[0037] like Figure 2-Figure 3As shown, in this embodiment, specifically, the adjustment assembly 5 includes a dual-rotor motor 51, an adjustment screw 52 is installed at the output end of the dual-rotor motor 51, and a threaded hole and two groups of limiting holes are respectively opened on the support block 31. The two groups of adjustment screws 52 are respectively connected to the threaded holes on the two groups of support blocks 31, and multiple groups of limiting rods are respectively connected to the limiting holes;

[0038] When in use, the adjustment component 5 of the device can adjust the positions of the two groups of limit saddles 3, because in the initial stage of use, it is necessary to adjust the positions of the two groups of support saddles 2 according to the size of the liquid tank to match the current liquid tank. During specific use, after determining the size of the liquid tank, the staff can start the dual-rotor motor 51 to drive the adjusting screw 52 at both ends to rotate, because the adjusting screw 52 is threadedly connected to the threaded hole on the support block 31, and can drive the limit saddle 3 to move toward the support saddle 2, and the limit rod is used to limit the moving direction of the limit saddle 3.

[0039] like Figure 5 As shown, in this embodiment, specifically, the test assembly 4 includes a mounting ball 41, which needs to be placed in the liquid tank. The mounting ball 41 is electrically connected to the controller 8. A counterweight 42 is installed inside the mounting ball 41. A receiving coil 43 is installed at the bottom of the counterweight 42. The receiving coil 43 is electrically connected to the transmitting coil 22. The counterweight 42 is installed inside the mounting ball 41 through a bearing. A support rod 44 is installed above the counterweight 42. A plurality of pressure sensing plates 45 are installed on the support rod 44. The pressure sensing plates 45 are in contact with the inner wall of the mounting ball 41.

[0040] When in use, the test component 4 of the device can detect the water pressure in the liquid tank. When in use, first, the mounting ball 41 needs to be placed inside the liquid tank. The mounting ball 41 will move to the designated position with the water flow and be fixed at the designated position by magnetism. At this time, energy is transmitted through the magnetic field coupling between the transmitting coil 22 and the receiving coil 43, so that the mounting ball 41 is wirelessly charged to ensure that the mounting ball 41 can be used continuously. During the movement of the mounting ball 41, because the counterweight block 42 is installed in the mounting ball 41 through the bearing, the counterweight ball will always be horizontally downward, ensuring that the support rod 44 and multiple sets of pressure sensing plates 45 can always face upward, and because the pressure sensing plate 45 is close to the inner top of the mounting ball 41, when the liquid presses the outer shell of the mounting ball 41, the outer shell of the mounting ball 41 will be concave, which will squeeze the pressure sensing plate 45, and the value will be transmitted to the controller 8 through the pressure sensing plate 45, so that the mounting ball 41 of the device can test the water pressure during the transportation of the liquid tank.

[0041] like Figure 5As shown, in this embodiment, specifically, the mounting ball 41 is made of plastic, and the counterweight 42 is made of iron. The weight of the counterweight 42 is greater than the weight of the support rod 44 and the plurality of pressure sensing plates 45 , and the counterweight 42 occupies 20% to 30% of the volume of the mounting ball 41 ;

[0042] Because the mounting ball 41 is made of plastic, the outer shell of the mounting ball 41 will be dented to varying degrees when subjected to pressure, thereby cooperating with the pressure sensing plate 45 to effectively detect the water pressure. The function of the counterweight block 42 is not only to limit the position of the support rod 44, but also to assist the mounting ball 41 in sinking to the bottom of the liquid tank. Because the mounting ball 41 is made of plastic, the counterweight block 42 is required to assist in sinking the mounting ball 41 to the bottom of the liquid tank.

[0043] like Figure 1 As shown, in this embodiment, specifically, when the installation ball 41 is in the liquid tank: the counterweight block 42 forces the pressure sensing plate 45 to be located at the top;

[0044] When the mounting ball 41 is squeezed by water pressure, the plastic mounting ball 41 will squeeze the pressure sensing plate 45 and transmit the value to the controller 8 via an electrical signal.

[0045] When the mounting ball 41 sinks to the bottom of the liquid tank, the counterweight 42 will always move vertically downward, so that the pressure sensing plate 45 at the other end of the counterweight 42 will always move upward. When the water pressure increases, the mounting ball 41 will be recessed and press the pressure sensing plate 45. The pressure sensing plate 45 will transmit the numerical value to the controller 8 in order to understand the current water pressure in the liquid tank.

[0046] like Figure 1 and Figure 7 As shown, in this embodiment, specifically, air pressure detection components 7 are respectively installed above the limit saddle 3, one group of air pressure detection components 7 is connected to the water inlet, and the other group of air pressure detection components 7 is connected to the water outlet. The air pressure detection components 7 include wires, which are connected to the controller 8. The other end of the wire is equipped with a mounting plate 71, and an air pressure sensor 72 is installed at the bottom of the mounting plate 71. The air pressure sensor 72 is connected to the controller 8 through a wire.

[0047] When in use, the device can also detect the air pressure of the liquid tank, so that during transportation, the water pressure and air pressure of the liquid tank can be detected to ensure that the liquid tank will not leak during transportation. In specific use, when the liquid tank is filled with liquid, two sets of mounting plates 71 need to be installed to the water inlet and outlet of the liquid tank respectively to detect the air pressure of the liquid tank. When the liquid tank leaks, the air pressure sensor 72 can quickly obtain the change in air pressure, thereby transmitting the information to the controller 8 so that the staff can know the current status of the liquid tank.

[0048] like Figure 1 As shown, in this embodiment, specifically, a controller 8 is installed inside the support saddle 2, and a control panel 81 is installed on the side of the support saddle 2, and the control panel 81 is connected to the controller 8;

[0049] Therefore, when the device is in use, the staff can operate the device through the control panel 81 and can know the current status of the liquid tank through the control panel 81.

[0050] Working principle: When the device is in use, first, the distance between the supporting saddle 2 and the limiting saddle 3 needs to be adjusted according to the size of the liquid tank, so as to adapt to liquid tanks of different sizes. At the same time, when the liquid tank is placed on the device from the crane, the buffer component 6 on the limiting saddle 3 will buffer the falling force of the liquid tank to prevent the instantaneous force from causing damage to the liquid tank or the device, thereby ensuring the safety of the device and the liquid tank. After the liquid tank is placed, the test component 4 needs to be placed inside the liquid tank, and then liquid is injected into the liquid tank. At this time, even if the test component 4 has not reached the specified position, it will It moves to the designated position under the impact of the water flow, and after the liquid tank is filled, the air pressure detection component 7 of the device needs to be installed at the water inlet and the water outlet respectively, so that when the liquid tank is transported, the changes in the internal water pressure and air pressure can be detected in real time to ensure that the liquid tank will not leak during transportation. Because the device fixes the liquid tank through the supporting saddle 2 and the two sets of limiting saddles 3, it can achieve a self-stabilizing effect on each liquid tank, and can detect the water pressure and air pressure in the liquid tank in real time, thereby ensuring the safety of the liquid tank during transportation.

[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
