An embodiment of the utility model provides a propellant storage tank system. As shown in fig. 1 and 2, comprises a tank case 1 for storing liquid fuel, at least one set of sensor assembly 2 for measuring a liquid level and a wall socket 3 for transmitting a liquid level measurement signal of the sensor assembly 2, which are provided along an axial direction of the tank case 1. The wall-through socket 3 is arranged in the upper part of the tank housing 1 (the upper part refers to the opposite side of the tank bottom) and is connected at one end to an electrical device (not shown) located outside the tank housing 1 and at the other end to the sensor assembly 2 located inside the tank housing 1 via a first cable 4. The sensor assembly 2 comprises a first sensor 21 close to the through-wall socket 3 and a second sensor 22 far from the through-wall socket 3, the first sensor 21 is located at the radial middle part of the inner side of the tank shell 1, the second sensor 22 is close to the inner side of the tank shell 1, and the first sensor 21 and the second sensor 22 are connected in series through a second cable 5.
In particular, the propellant tank system consists of a tank shell 1 for storing liquid fuel, at least one set of sensor assemblies 2 for measuring the liquid level arranged in the axial direction of the tank shell 1 and a wall socket 3 for transmitting a liquid level measuring signal of the sensor assemblies 2. The wall-through socket 3 is provided at the upper part of the tank housing 1 and is connected at one end to an electrical device (not shown) located outside the tank housing 1 and at the other end to the sensor assembly 2 located inside the tank housing 1 via a first cable 4. The sensor assembly 2 comprises a first sensor 21 close to the through-wall socket 3 and a second sensor 22 far from the through-wall socket 3, the first sensor 21 is located at the radial middle part of the inner side of the tank shell 1, the second sensor 22 is close to the inner side of the tank shell 1, and the first sensor 21 and the second sensor 22 are connected in series through a second cable 5. Because first sensor 21 and second sensor 22 pass through second cable 5 series connection, and the distance from the wall socket is different, avoided first sensor 21 and second sensor 22 to adopt under the condition of independent sensor respectively, cause the high frequency cable line overlength of measuring the remaining second sensor 22 of storage tank propellant, cause the incident, effectively improved propellant liquid level measurement's security and reliability.
It should be noted that, as shown in fig. 1, in order to simplify the arrangement of the level sensor inside the tank shell 1 and improve its stability inside the tank, for example, the first sensor 21 and the second sensor 22 may be located on the same side of the axis of the tank shell 1. For example, in the radial direction, the first sensor 21 is at a greater distance from the inner wall of the tank housing 1 than the second sensor 22 is at from the inner wall of the tank housing 1. It is worth mentioning that the first sensor 21 and the second sensor 22 may be the same length for convenience of measuring the liquid propellant level and for ease of installation.
In this embodiment, as shown in fig. 1 and 4, in order to avoid the first sensor 21 and the second sensor 22 from shaking, for example, the first clamp 6 and the second clamp 7 are respectively sleeved on the first sensor 21 and the second sensor 22, and one end of each of the first clamp 6 and the second clamp 7 is connected with the inner wall of the storage tank shell 1. The first collar 6 is located near the first sensor 21 near the end of the first cable 4 and the second collar 7 is located near the bottom end of the tank shell 1 at the second sensor 22. Through setting up first clamp 6 and second clamp 7 respectively at first sensor 21 and second sensor 22 for fixed first sensor 21 and second sensor 22 are fixed more firmly, in case in rocket flight process, avoid appearing the condition that the sensor rocked along with the storage tank.
It is further extended that, as shown in fig. 1, 3 and 4, in order to ensure the accuracy of the measurement, the first sensor 21 and the second sensor 22 are fixed more firmly, for example, a first tensile wire 8 for fixing the first sensor 21 and a second tensile wire 9 for fixing the second sensor 22 may be further provided on the first sensor 21 and the second sensor 22, respectively. For example, the first tension line 8 may be located at an end of the first sensor 21 remote from the first yoke 6, and the second tension line 9 may be located at an end of the second sensor 22 remote from the second yoke 7.
Specifically speaking, the two ends of the first sensor 21 are respectively fixed firmly through the first clamp 6 and the first tension wire 8, so that the shaking of the first sensor is avoided. Similarly, the two ends of the second sensor 22 are fixed firmly by the second clamp 7 and the second tension wire 9 respectively.
In the present embodiment, as shown in fig. 3 and 6, for example, the first and second wires 8 and 9 are wound around the first and second sensors 21 and 22, respectively, and the two end connectors of the first and second wires 8 and 9 are welded to the inner wall of the tank shell 1.
It should be noted that, as shown in fig. 1 and 3, for convenience of operation, for example, the first wire 8 is wound on the first sensor 21 in the same manner as the second wire 9 is wound on the second sensor 22, and the lengths of the two wires are equal.
Further, as shown in fig. 1 and 5, the second cable 5 may expand with heat and contract with cold, so that the surface of the second cable 5 is stressed, and the second cable 5 is broken due to lack of support for the second cable 5. In order to avoid the second cable 5 from being broken, for example, the second cable 5 is fixed to the third wire 10, and both ends of the third wire 10 are connected to end surfaces of the first sensor 21 and the second sensor 22 near each other, respectively. For example, the length of the second cable 5 is greater than the length of the third tensile wire 10, in this embodiment, both ends of the second cable 5 are fixed to the third tensile wire 10, and at least one fixed point in the middle of the second cable 5 is connected to the third tensile wire 10, so that the change of the length of the cable in the variable temperature environment can be better adapted, and the cable can be prevented from breaking. In the practical application process, the connection point between the middle part of the second cable 5 and the third wire 10 can be increased according to the practical requirement.
In this embodiment, for example, the third wire 10 can be understood as a support column on which the second cable 5 is looped, and the support column supports the second cable 5. In the process of wrapping the second cable 5 around the support column, a part of the surface of the second cable 5 may contact with the support column, and another part of the surface of the second cable 5 may have a gap with the support column, so as to facilitate expansion and contraction of the second cable 5, which will not be described herein.
It is worth mentioning that the electrical device may be, for example, a transducer for converting a signal from the sensor assembly via the transducer.
One or more of the above embodiments or a portion of one embodiment and a portion of another embodiment or embodiments may be combined with each other and have corresponding technical effects.
The utility model also provides a rocket structure contains propellant storage tank system's technical characterstic.
The foregoing is only an illustrative embodiment of the present invention, and any equivalent changes and modifications made by those skilled in the art without departing from the spirit and principles of the present invention should fall within the protection scope of the present invention.
