Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of liquid tank trucks, and particularly relates to a flexible wave-preventing structure and a liquid tank truck. BACKGROUND

[0002] During driving, liquid in the tank body shakes back and forth due to complex working conditions such as sudden braking, and therefore, a plurality of wave-preventing plates are usually arranged in the tank body to buffer the impact of liquid shaking.

[0003] At present, the general wave-preventing plate blocks the liquid impact load by the wave-preventing plate body. While the existing wave-preventing plate blocks the liquid impact load, it causes excessive force on itself, resulting in stress concentration at the local position of the wave-preventing plate. Long-term repeated impact load can cause fatigue failure of the wave-preventing plate, resulting in crack failure at the local position of the wave-preventing plate.

[0004] In the long run, the wave-preventing plate is easily impacted by the shaking liquid and is prone to damage. Moreover, the wave-preventing plate is generally welded and fixed in the tank body. Therefore, it is troublesome to maintain and replace the wave-preventing plate after damage. SUMMARY

[0005] The technical problem to be solved by the present application is to overcome the shortcomings of the prior art and provide a flexible wave-preventing structure and a liquid tank truck to solve the problem of easy damage and subsequent maintenance and replacement of the wave-preventing plate.

[0006] On the one hand, the technical scheme for solving the above technical problem is as follows: a flexible wave-preventing structure applied to a tank body of a liquid tank truck, comprising:

[0007] An outer ring plate is matched and connected to the inner wall of the tank body, and a through hole is formed in the center of the outer ring plate;

[0008] An inner plate is arranged in the through hole in the center of the outer ring plate with a gap;

[0009] A plurality of elastic members are sequentially arranged along the outer periphery of the inner plate, one end of the elastic member is connected to the inner plate, the other end is connected to the outer ring plate, and the elastic member is used to form an elastic gap between the inner plate and the outer ring plate.

[0010] Compared with the prior art, the above technical scheme has the following beneficial effects:

[0011] The outer ring plate is fixed to the inner wall of the tank body, a through hole for liquid flowing through is formed in the center of the outer ring plate, and the inner plate is connected to the outer ring plate through a plurality of elastic members.

[0012] Further, the rigidity of the elastic member gradually decreases from top to bottom.

[0013] Further, the tank body is provided with a vacancy at the circumferential bottom position, and the plurality of elastic members are uniformly arranged at the circumferential stroke outside the vacancy.

[0014] Further, the outer ring plate comprises two ring-shaped single plates, the inner rings of the two ring-shaped single plates are combined at one place, and the outer rings of the two ring-shaped single plates gradually separate to two sides and are connected and fixed to the inner wall surface of the tank body.

[0015] Further, the outer ring plate comprises:

[0016] The outer side of the reinforcing lining plate is arranged on the inner wall of the tank body;

[0017] The annular plate is formed by the two ring-shaped single plates, and the outer ring of the annular plate is connected to the inner side of the reinforcing lining plate.

[0018] Further, the inner plate is arranged as an arc-shaped inner plate with a central side arching.

[0019] Further, the outer ring plate is provided with a flow guide hole at the bottom.

[0020] Further, the outer ring plate is provided with a reinforcing pad plate on both sides of the flow guide hole, and the reinforcing pad plate is arranged between the outer ring plate and the tank body.

[0021] Further, the length of the reinforcing pad plate in the direction perpendicular to the plane of the outer ring plate is greater than the width of the outer ring plate in the direction.

[0022] The one or more technical solutions provided in the embodiments of the application have at least the following technical effects or advantages:

[0023] 1. The inner plate and the outer ring plate are connected through a plurality of elastic members, when the liquid impacts the anti-sloshing plate, the inner plate is deformed by the impact load, the elastic member is elongated, the gap between the inner plate and the outer ring plate is enlarged, and the liquid can flow through the anti-sloshing plate through the elastic gap. The anti-sloshing plate resists the impact force of the liquid through the elastic deformation of the elastic member, and the impact on other parts of the anti-sloshing plate is small, and it is not easy to be damaged due to stress concentration.

[0024] 2. The rigidity of the elastic member gradually increases from top to bottom, when the liquid level hits the wave plate, the upper opening of the wave plate is small, and the lower opening is large, most of the liquid can pass through the wave plate from the lower side.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0044] As Figures 1-5 shown, a flexible wave-proof structure provided by the present application is applied to a tank body of a liquid tank truck, which comprises an outer ring plate, an inner plate and a plurality of elastic members.

[0045] The outer ring plate is matched and connected to the inner wall of the tank body, a through hole is formed in the center of the outer ring plate, the central through hole is used for flowing of liquid, the inner plate is arranged in the through hole in the center of the outer ring plate, a gap is formed between the inner plate and the through hole, that is, the outer diameter of the inner plate is smaller than the diameter of the through hole, the inner plate can move forward and backward in the through hole to form a larger gap to facilitate the flow of liquid, the elastic members are sequentially arranged along the outer periphery of the inner plate, one end of the elastic member is connected to the inner plate, the other end is connected to the outer ring plate, and the elastic member is used for forming an elastic gap between the inner plate and the outer ring plate, when the liquid impacts the inner plate, the elastic member itself has an elastic force and is elongated, in this way, the inner plate is pulled by the elastic force of the elastic member, an elastic gap is formed between the inner plate and the outer ring plate, the greater the impact force of the liquid, the greater the elastic gap, and the smaller the impact force, the smaller the elastic gap.

[0046] In the embodiment, the outer ring plate is fixed to the inner wall of the tank body, a through hole for flowing of liquid is formed in the center of the outer ring plate, the outer periphery of the inner plate is connected to the outer ring plate through a plurality of elastic members, when the liquid shakes back and forth, the elastic members are elongated, a gap is formed between the inner plate and the outer ring plate, and the liquid passes through the gap, the inner plate and the outer ring plate connected through the elastic members can resist the impact force of the liquid by using the elastic force, and after long-term use, only the elastic members need to be replaced, so that the replacement is convenient, and in addition, the impact of the shaking liquid on the inner plate and the outer ring plate is small, and the service life is long.

[0047] In the embodiment, since the elastic members are arranged in multiple and sequentially arranged from top to bottom along the periphery of the inner plate, the rigidity of the elastic members is gradually reduced from top to bottom, when the inner plate is impacted by the liquid, since the rigidity of the lower elastic member is smaller, the elastic gap formed below the inner plate is greater than the elastic gap above, and the liquid passing through the elastic gap is preferentially passed from the lower part of the anti-wave plate, and the elastic member can be a tension spring with different rigidity.

[0048] The tank body is formed with a vacancy at the circumferential bottom position, a plurality of elastic members are uniformly and spacedly arranged on the circumferential stroke outside the vacancy, the vacancy is formed at the bottom position, and no elastic member is arranged on the vacancy, in this way, the position below the inner plate is more easily stretched to form a larger elastic gap when impacted by the liquid due to the lack of traction of the elastic member.

[0049] Specifically, the elastic member is provided with 11 elastic members, one elastic member with the highest rigidity is arranged at the top opposite to the vacancy, the inner plate top is connected to the outer ring plate by using the elastic member, the remaining 10 elastic members are symmetrically distributed on the two side edges of the inner plate, no elastic member is arranged at the bottom position of the inner plate to form a vacancy, and the rigidity of the elastic members symmetrically arranged on each side is consistent.

[0050] In addition, since the personnel need to maintain and overhaul the wave plate inside the tank body, due to the small rigidity of the elastic element under the lower inner plate, and a vacancy is formed, the personnel can manually push the lower inner plate to open the inner plate to form an open state, and the personnel can pass through the elastic gap between the inner plate and the outer ring plate at the vacancy, and then the maintenance operation can be performed in the tank body.

[0051] In the embodiment, hooks are arranged at both ends of the elastic element, and a plurality of hook holes matched with the hooks are arranged on the inner plate and the outer ring plate in a circumferential direction, and the hooks and the hook holes are matched to form detachable connection, so that the elastic element can be conveniently and quickly replaced and maintained in the future.

[0052] In the embodiment, the outer ring plate includes two annular single plates, and the two annular single plates form a herringbone structure in a cross section, that is, the inner ring of the annular single plate is combined at one place, and the outer ring of the annular single plate is gradually separated to two sides and connected and fixed with the inner wall surface of the tank body, so that the two annular single plates and the inner wall surface of the tank body form a triangular structure in a cross section, so that the entire outer ring plate has high structural strength and strong impact resistance, and the liquid impacting on the outer ring plate is guided to the gap at the outer periphery of the inner plate, not only the structure is stable, but also has a certain flow guiding effect.

[0053] In addition, in the embodiment, the outer ring plate further includes a reinforcing lining plate, the annular plate formed by the two annular single plates is arranged on the inner side surface of the reinforcing lining plate, and the outer side surface of the reinforcing lining plate is arranged in abutment with the inner wall surface of the tank body, and the outer ring of the annular plate is connected with the inner side surface of the reinforcing lining plate, so that the reinforcing lining plate arranged between the annular plate and the tank body can further improve the structural strength of the entire outer ring plate and the stability of the connection with the inner wall of the tank body.

[0054] The inner plate is arranged as an arc-shaped inner plate arched toward one side of the center, and the direction of the arch of the inner plate is toward the front, that is, the front of the vehicle running, and generally, the working condition is the most harsh when the vehicle is suddenly braked, the liquid impacts the concave surface of the inner plate from the rear, and due to the strong front convex inner plate structure, the load is larger, the stress and deformation are smaller, the liquid can be blocked, and the stress concentration phenomenon of the inner plate itself can be avoided.

[0055] In an embodiment, a flow guide hole is arranged at the bottom of the outer ring plate, and the flow guide hole is arranged on the reinforcing lining plate and the annular plate and located at the lowest position of the outer ring plate.

[0056] The reinforcing pad plates are arranged on both sides of the flow guide hole of the outer ring plate, and the reinforcing pad plates are arranged between the outer ring plate and the tank body, and specifically, the reinforcing pad plates are located between the reinforcing lining plate and the inner wall of the tank body, and since the flow guide hole is arranged, the structural strength of the outer ring plate at this position is insufficient, and the reinforcing pad plates need to be supplemented to increase the connection strength between the outer ring plate and the tank body.

[0057] The reinforcing gusset plates on both sides extend to the direction of the inward flow guide hole, and the extension ends do not contact, so as to ensure that there is no dead accumulation on the inner bottom of the tank body.

[0058] The length of the reinforcing gusset plate in the direction perpendicular to the surface of the outer ring plate is greater than the width of the outer ring plate in the direction, that is, the length of the reinforcing gusset plate is greater than the width of the outer ring plate in the axial direction of the tank body and the outer ring plate, so as to better strengthen the structural strength of the outer ring plate at the flow guide hole.

[0059] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
