Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

A liquid storage container 10 according to an embodiment of the present invention is described below with reference to fig. 1 to 7. It should be noted that the reservoir 10 can be used on an aircraft, or other plant protection equipment such as a farm robot.

As shown in fig. 1-7, a liquid storage container 10 according to an embodiment of the present invention. The liquid storage container 10 includes a case 11, a connection pipe 12, and a liquid level measurer 13. As shown in fig. 3, the housing 11 may define a liquid storage chamber 111, and the connection pipe 12 is disposed through the liquid storage chamber 111 for draining the liquid medicine in the liquid storage chamber 111. The liquid level measuring device 13 is vertically inserted into the liquid storage chamber 111 for detecting the liquid medicine storage amount in the liquid storage chamber 111.

Specifically, as shown in fig. 3, a reservoir chamber 111 may be provided in the housing 11, a bottom wall of the reservoir chamber 111 may have a first pipe joint 112, and a side wall of the reservoir chamber 111 may have a second pipe joint 113. Therefore, by constructing the first pipe joint 112 on the bottom wall of the liquid storage cavity 111 and constructing the second pipe joint 113 on the side wall of the liquid storage cavity 111, the first pipe joint 112 can be used as an inlet pipe for conveying the liquid medicine in the liquid storage cavity 111 outwards, and the second pipe joint 113 can be used as an outlet pipe for conveying the liquid medicine outwards, so that when the aircraft 1 performs spraying operation, the first pipe joint 112 arranged on the bottom wall can sufficiently guide the liquid medicine to flow, and the probability of liquid medicine remaining can be reduced.

For example, as shown in FIG. 3, the reservoir 111 includes an upper reservoir 1111 and a lower reservoir 1112, the upper reservoir 1111 is located above the lower reservoir 1112, the upper reservoir 1111 is in communication with the lower reservoir 1112, the first adapter 112 is located at the bottom wall of the lower reservoir 1112, and the second adapter 113 is located at the bottom wall of the upper reservoir 1111.

As shown in fig. 3, the connection pipe 12 includes a first pipe section 121 and a second pipe section 122. One end of the first pipe section 121 is connected and communicated with the first pipe joint 112, one end of the second pipe section 122 is connected and communicated with the other end of the first pipe section 121, the other end of the second pipe section 122 can be connected and communicated with the second pipe joint 113, and the second pipe section 122 is a hard pipe for limiting the trend of the connecting pipe 12.

Thus, by configuring the connection pipe 12 as the first pipe section 121 and the second pipe section 122 connected and communicated, and providing the second pipe section 122 as a hard pipe for defining the direction of the connection pipe 12, the second pipe section 122 can be used as a support structure for the first pipe section 121, thereby reducing the probability of the first pipe section 121 being bent or deflected, further reducing the probability of the first pipe section 121 interfering with other elements (e.g., the liquid level measurer 13) in the reservoir 111, and improving the reliability of the reservoir.

In addition, the second pipe section 122 may serve as a transition structure between the first pipe section 121 and the second pipe joint 113, so as to enable the liquid medicine in the first pipe section 121 to smoothly flow to the second pipe joint 113 through the second pipe section 122. For example, when there is a large deviation between the flow direction of the liquid medicine in the first pipe section 121 and the flow direction of the liquid medicine in the second pipe joint 113, the second pipe section 122 may be configured to have a bent section, so that the flow of the liquid medicine may be changed while the flow direction of the liquid medicine is smoothly circulated.

For example, as shown in fig. 3, the first pipe section 121 is vertically disposed, the second pipe section 122 is an arc-shaped structure, and the second pipe section 122 is disposed through the upper reservoir 1111 and the lower reservoir 1112. The lower end of the first pipe section 121 is connected to and communicated with the opening of the first pipe joint 112, the upper end of the first pipe section 121 is connected to and communicated with the left end opening of the second pipe section 122, and the right end opening of the second pipe section 122 is connected to and communicated with the second pipe joint 113.

It should be noted that when the aircraft 1 performs the spraying operation, the liquid medicine in the liquid storage chamber 111 flows into the first pipe section 121 through the first pipe joint 112, the liquid medicine in the first pipe section 121 is conveyed to the second pipe joint 113 along the second pipe section 122, and the second pipe joint 113 can convey the liquid medicine to the spray head through the pipe connection and spray the liquid medicine to the outside (the "outside" here can be understood as a space outside the tank 11).

According to the liquid storage container 10 of the embodiment of the present invention, by configuring the connection pipe 12 as the first pipe segment 121 and the second pipe segment 122 connected and communicated with each other, and setting the second pipe segment 122 as a rigid pipe, on one hand, the second pipe segment 122 can be used as a support structure for the first pipe segment 121, so as to reduce the probability of the first pipe segment 121 bending or deviating, and further reduce the probability of the first pipe segment 121 interfering with other elements in the liquid storage cavity 111, thereby improving the reliability of the liquid storage container 10; on the other hand, the second pipe segment 122 may be used as a transition structure between the first pipe segment 121 and the second pipe joint 113, so as to improve the smoothness of the liquid medicine flowing in the connection pipe 12.

As shown in fig. 3, according to some embodiments of the present invention, the liquid storage container 10 further includes a liquid level measuring device 13, the liquid level measuring device 13 is disposed in the liquid storage cavity 111, the lower end of the liquid level measuring device 13 can be connected to the bottom wall of the liquid storage cavity 111, the upper end of the liquid level measuring device 13 can be connected to the top wall of the liquid storage cavity 111, and the liquid level measuring device 13 can be spaced apart from the first pipe section 121. Therefore, by arranging the liquid level measuring device 13 and the first pipe section 121 at an interval, the probability of interference between the first pipe section 121 and the liquid level measuring device 13 can be reduced, and the accuracy and reliability of detection of the liquid level measuring device 13 can be improved.

For example, as shown in fig. 3, the liquid level measuring device 13 is vertically inserted into the liquid storage chamber 111, the liquid level measuring device 13 is located on the left side of the first pipe section 121, and the liquid level measuring device 13 is spaced apart from the first pipe section 121 in the left-right direction.

As shown in fig. 3, according to some embodiments of the present invention, reservoir 111 may include an upper reservoir 1111 and a lower reservoir 1112, with upper reservoir 1111 positioned above lower reservoir 1112 and upper reservoir 1111 in communication with lower reservoir 1112. Therefore, by configuring the reservoir 111 as the upper reservoir 1111 and the lower reservoir 1112 which are communicated with each other, the upper reservoir 1111 and the lower reservoir 1112 can be used as relatively independent accommodating spaces, so that the layout of the working elements in the reservoir 111 can be optimized, and the probability of interference between the working elements in the upper reservoir 1111 and the working elements in the lower reservoir 1112 can be reduced.

As shown in FIG. 3, first adapter 112 is positioned at a bottom wall of lower reservoir 1112, second adapter 113 is positioned at a bottom wall of upper reservoir 1111, and one end of second tubing segment 122 extends toward lower reservoir 1112. Accordingly, the end portion of the second pipe section 122 extending toward the lower reservoir 1112 can be used as the connecting end portion of the second pipe section 122 and the first pipe section 121, so that the connecting end portion of the first pipe section 121 from the first pipe joint 112 to the second pipe section 122 can be extended linearly, and the probability of interference between the first pipe section 121 and the liquid level measuring instrument 13 due to bending of the first pipe section 121 can be reduced.

For example, as shown in fig. 3, the opening of the first pipe connector 112 provided in the bottom wall of the lower reservoir chamber 1112 faces upward, the left end portion of the second pipe section 122 extends toward the lower reservoir chamber 1112, and the first pipe section 121 is connected between the opening of the first pipe connector 112 and the opening of the left end portion of the second pipe section 122. As shown in fig. 3 and 6, according to some embodiments of the present invention, the second pipeline section 122 may be a U-shaped pipe. Therefore, by configuring the second pipe section 122 as a U-shaped pipe, the liquid medicine in the first pipe section 121 can be smoothly drained to the second pipe joint 113 by using the bent section of the U-shaped pipe, so as to improve the smoothness of the liquid medicine flowing in the connecting pipe 12, and the characteristic of easy forming of the U-shaped pipe can be used, so that the cost is saved.

As shown in fig. 3, according to some embodiments of the present invention, one end of the second pipe segment 122 may be located directly or obliquely above the first pipe joint 112. It should be noted that an end of the second pipe section 122 located directly above or obliquely above the first pipe joint 112 may be used as a connection end of the second pipe section 122 to the first pipe section 121. At this time, one end of the second pipe section 122 is disposed opposite to the opening of the first pipe joint 112 in the up-down direction.

Therefore, the first pipe section 121 connected between the second pipe section 122 and the first pipe joint 112 may be disposed in the vertical direction, and the length of the first pipe section 121 may be approximately equal to the distance between the second pipe section 122 and the first pipe joint 112, so as to avoid the first pipe section 121 bending toward the liquid level measuring device 13 due to the overlong first pipe section 121, and further reduce the probability of interference between the first pipe section 121 and the liquid level measuring device 13, so as to improve the reliability of the liquid level measuring device 13.

For example, as shown in fig. 3, the left end of the second pipe section 122 is located right above the first pipe joint 112, the first pipe section 121 extends in the vertical direction, and the upper end of the first pipe section 121 is connected to and communicates with the left end of the first pipe section 122.

According to some embodiments of the present invention, the second pipe section 122 may be a rigid pipe, the first pipe section 121 is a flexible pipe, and the hardness of the second pipe section 122 is greater than the hardness of the first pipe section 121 at this time. Therefore, the structural strength of the second pipe section 122 can be improved by using the structural characteristics that the hard pipe is not easy to deform, so that the probability that the first pipe section 121 is bent or liquid medicine is not smoothly circulated due to the deformation of the second pipe section 122 can be reduced, and the reliability of the connecting pipe 12 can be improved.

In addition, by providing the first pipe segment 121 as a flexible pipe, the fault tolerance of the layout of the connection pipe 12 in the reservoir chamber 111 can be improved. For example, when there is an interference structure on the layout route of the first pipe segment 121, the first pipe segment 121 may bypass the interference structure, thereby enabling the connection pipe 12 to be completely installed.

It should be noted that, at the joint of the first pipeline section 121 and the second pipeline section 122, the rigid pipe may be used as a support structure to improve the stability of the joint, and the flexible pipe may utilize the deformable characteristic thereof to tightly connect the flexible pipe and the rigid pipe, thereby improving the sealing performance of the joint.

Of course, the hardness of the first pipe section 121 is not limited to this, for example, in other examples, the first pipe section 121 may also be a hard pipe, so that the structural strength of the first pipe section 121 may be improved by using the structural characteristic that the hard pipe is not easily deformed, and the first pipe section 121 may be prevented from being deformed.

As shown in fig. 4 and 6, according to some embodiments of the present invention, the outer wall of one end of the second pipe segment 122 may have a clamping step 1221, and the first pipe segment 121 may be sleeved on the clamping step 1221. Therefore, the connection tightness between the first pipe section 121 and the second pipe section 122 can be improved, and the connection manner between the first pipe section 121 and the second pipe section 122 can be simplified, thereby facilitating the detachment and installation of the first pipe section 121 and the second pipe section 122.

Further, as shown in fig. 4 and 6, the catching step 1221 may extend in the circumferential direction of the second pipe segment 122. Therefore, when the first pipe section 121 is sleeved on the clamping step 1221, the inner peripheral wall of the first pipe section 121 is tightly and uniformly matched with the clamping step 1221, so that the probability of a gap at the joint of the first pipe section 121 and the second pipe section 122 is reduced, and the reliability of the connecting pipe 12 can be improved.

In some embodiments, as shown in fig. 4 and 6, the clamping step 1221 may be multiple, and the multiple clamping steps 1221 may be sequentially arranged along the length direction of the second pipeline segment 122. Thereby, the fastening and reliability of the connection of the first pipe section 121 and the second pipe section 122 can be improved. It will be appreciated that when one of the plurality of snap steps 1221 is damaged, the remaining snap steps 1221 can still be fittingly connected to the first pipeline section 121 to maintain the connection between the first pipeline section 121 and the second pipeline section 122.

For example, as shown in fig. 4 and 6, two clamping steps 1221 are configured on the outer wall surface of the second pipe section 122 at the end of the lower reservoir 1112, the two clamping steps 1221 are all disposed around the outer circumference of the second pipe section 122, the two clamping steps 1221 are sequentially arranged in the up-down direction, and the upper end of the first pipe section 121 may be sleeved on the clamping steps 1221.

As shown in fig. 3, according to some embodiments of the present invention, the opening direction of the first pipe joint 112 may be away from the liquid level measurer 13. Therefore, by providing the opening direction of the first pipe joint 112 away from the liquid level measuring device 13, the extending direction of the first pipe section 121 toward the second pipe section 122 can be made to tend to be away from the liquid level measuring device 13, so that the distance between the liquid level measuring device 13 and the first pipe section 121 can be increased, and the probability of interference between the first pipe section 121 and the liquid level measuring device 13 can be reduced. For example, as shown in fig. 3, the liquid level gauge 13 is located on the left side of the first pipe joint 112, and the end of the first pipe joint 112 connected to the first pipe section 121 is open toward the upper right side.

As shown in fig. 3, according to some embodiments of the present invention, the bottom wall of the reservoir chamber 111 may have a recess 114, and the first pipe joint 112 may be disposed in the recess 114. Therefore, the first pipe joint 112 is arranged at the recessed portion 114, so that the first pipe joint 112 can be located at the bottom of the liquid storage cavity 111, the liquid medicine in the liquid storage cavity 111 can be conveniently and fully drained to the connecting pipe 12 through the first pipe joint 112, the liquid medicine residue is reduced, and the performance of the liquid storage container 10 is improved. In addition, the recess 114 may define a relatively independent receiving space, so that the probability of interference of other elements within the reservoir 111 with the first coupling 112 may be reduced.

As shown in fig. 4 and 6, according to some embodiments of the present invention, the second pipe joint 113 may be provided with a liquid passing valve 14. Thereby, the liquid passing valve 14 can be used as a control switch to open or close the liquid medicine spraying outlet when the aircraft 1 is performing spraying work.

The aircraft 1 according to the embodiment of the present invention includes the liquid storage container 10.

According to the aircraft 1 of the embodiment of the present invention, by configuring the connecting pipe 12 as the first pipe segment 121 and the second pipe segment 122 that are connected and communicated, and setting the second pipe segment 122 as a rigid pipe, on one hand, the second pipe segment 122 can be used as a supporting structure for the first pipe segment 121, so as to reduce the probability of the first pipe segment 121 bending or deviating, and further reduce the probability of the first pipe segment 121 interfering with other elements in the liquid storage cavity 111, thereby improving the reliability of the liquid storage container 10; on the other hand, the second pipe segment 122 may be used as a transition structure between the first pipe segment 121 and the second pipe joint 113, so as to improve the smoothness of the liquid medicine flowing in the connection pipe 12.

A liquid storage container 10 according to an embodiment of the present invention is described in detail below with reference to fig. 1 to 7. It is to be understood that the following description is illustrative only and is not intended as a specific limitation on the invention.

As shown in fig. 1, a liquid storage container 10 is provided on a fuselage 20 of the aircraft 1, and the liquid storage container 10 may be used for storing liquid medicine for spraying operation of the aircraft 1.

As shown in fig. 2 and 3, the liquid storage container 10 has a box body 11, and the box body 11 may include an upper box body 117 and a lower box body 118, and the upper box body 117 and the lower box body 118 are both formed as a long-strip-shaped box body 11. The upper case 117 is located above the lower case 118 and the bottom wall of the upper case 117 is vertically connected to the side wall of the lower case 118, and the upper case 117 and the lower case 118 are constructed to form a "T" structure, so that the stability and the accommodation capacity of the case 11 can be improved. The upper housing 117 may define an upper reservoir 1111 and the lower housing 118 may define a lower reservoir 1112, the upper reservoir 1111 communicating with the lower reservoir 1112 to form the reservoir 111.

As shown in fig. 3, the liquid reservoir 10 includes a first pipe joint 112, a second pipe joint 113, and a connection pipe 12. The first adapter 112 is positioned on the bottom wall of the lower reservoir 1112 and the second adapter 113 is positioned on the bottom wall of the upper reservoir 1111. The connection pipe 12 includes a first pipe section 121 and a second pipe section 122, the first pipe section 121 is disposed in the vertical direction, the second pipe section 122 is a U-shaped pipe, and the second pipe section 122 penetrates through the upper reservoir 1111 and the lower reservoir 1112. Therefore, the bending section of the U-shaped pipe can be used to smoothly guide the liquid medicine in the first pipe section 121 to the second pipe joint 113, so as to improve the smoothness of the liquid medicine flowing in the connecting pipe 12

As shown in fig. 3, the lower end of the first pipe segment 121 is connected to and communicates with the opening of the first pipe joint 112, the upper end of the first pipe segment 121 is connected to and communicates with the left end opening of the second pipe segment 122, and the right end opening of the second pipe segment 122 is connected to and communicates with the opening of the second pipe joint 113. Thus, the first pipe joint 112, the first pipe section 121, the second pipe section 122, and the second pipe joint 113 are connected and communicated in this order, and can constitute a chemical liquid transfer line of the liquid storage container 10.

It should be noted that the second pipe section 122 is a hard pipe. Accordingly, the second pipe section 122 can be used as a support structure for the first pipe section 121, thereby reducing the probability of the first pipe section 121 being bent or displaced, and further reducing the probability of the first pipe section 121 interfering with other components in the reservoir chamber 111, and improving the reliability of the reservoir.

As shown in fig. 3 and 7, the liquid storage container 10 includes a liquid level measuring device 13, the liquid level measuring device 13 includes a float 131 and a sensing device 132, and the float 131 can slide along the sensing device 132. As shown in fig. 3, the liquid level measuring device 13 is vertically inserted into the liquid storage chamber 111, the sensing device 132 is a rod-shaped structure, and the float 131 is sleeved on the sensing device 132. It is understood that the float 131 may float up and down along the sensing device 132 according to the change of the level of the liquid medicine in the reservoir chamber 111, so that the amount of the liquid medicine stored in the reservoir chamber 111 can be detected by using the position of the float 131.

As shown in fig. 3, the liquid level measuring device 13 is located on the left side of the first pipe section 121, and the liquid level measuring device 13 is spaced apart from the first pipe section 121 in the left-right direction. Thereby, the probability of interference of the first pipe section 121 with the liquid level measuring device 13 can be reduced, and the accuracy and reliability of detection of the liquid level measuring device 13 can be improved.

As shown in fig. 3, the left end of the second pipe section 122 is located right above the first pipe joint 112, the upper end of the first pipe section 121 is connected to and communicates with the left end of the second pipe section 122, and the lower end of the first pipe section 121 is connected to and communicates with the first pipe joint 112. Thus, the length of the first pipe section 121 can be consistent with the distance between the second pipe section 122 and the first pipe joint 112, so as to avoid the first pipe section 121 bending towards the liquid level measuring device 13 due to the overlong first pipe section 121.

As shown in FIG. 3, a recess 114 is formed in the bottom wall of the lower reservoir 1112 and the first adapter 112 is received in the recess 114. Therefore, the first pipe joint 112 can conveniently and fully drain the liquid medicine in the liquid storage cavity 111 to the connecting pipe 12, and the liquid medicine residue is reduced. As shown in fig. 3, the recess 114 is formed with a first connection port 115 on an outer wall thereof, and the first pipe joint 112 is adapted to pass through the first connection port 115. The first connector port 115 is formed at an outer circumference thereof with a first connection portion 1151 protruding downward, and the first pipe joint 112 is formed with a first fixing portion 1121, and the first fixing portion 1121 is screw-coupled to the first connection portion 1151 for mounting the first pipe joint 112.
