The alternate sections 4 can move in the water tank main body 3 in a direction parallel to the accommodating cavity 5, when the alternate sections 4 slide to a certain position in the water tank main body 3, a circulation cavity (a left cavity in fig. 7) is formed between the surface of one side of the alternate sections 4 far away from the driving mechanism 6 and the inner wall of one end of the water tank main body 3 close to the alternate sections 4, and when the pushing block moves in the movable interval 7, two ends of the accommodating cavity 5 are respectively communicated with the circulation cavity and the movable interval 7 and are combined to form a concave structure.
According to the invention, the wave water tank and the oscillation water flow tank can be alternately used through the cooperation of the wave section 1, the gentle section 2 and the alternate section 4, specifically, if the wave water tank is needed to be used, the driving mechanism 6 is only started, then the top end of the wave section 1 is pushed by the driving mechanism 6 and is inclined and deflected towards the alternate section 4 by a set angle through the bottom end of the wave section 1 as a rotation center, and at the moment, the top end of the wave section 1 is repeatedly guided to deflect so that liquid can move in a wave shape in the water tank main body 3; if an oscillating water flowing groove is needed, the alternating sections 4 are guided to move in the water groove main body 3 in the direction parallel to the containing cavity 5 until a certain position, the circulating cavity is formed at the moment, two ends of the containing cavity 5 are respectively communicated with the circulating cavity and the movable interval 7 and are combined to form a concave structure, and then the pushing block is guided to move along the direction perpendicular to the containing cavity 5, so that liquid can move in the concave structure.
It should be noted that:
the set angle of deflection of the wave segment 1 is preferably 0-45 degrees, if exceeded, water is liable to enter the active space 7 from the top of the wave segment 1.
The main improvement point of the invention is how to quickly realize the alternation of the wave water tank and the oscillation water flow tank, and the data acquisition mode can select the prior art in the alternation process, so that the invention does not have excessive requirements.
The specific structure of the driving mechanism 6 in the invention is shown in fig. 1, 2, 3, 4, 5 and 7, and comprises a driver (such as an electric push rod and other lifting devices) fixed on the water tank main body 3 and a driving head connected with the driver, wherein the driving head comprises a shaft sleeve connected with the output end of the driver, a shaft post movably connected with a pushing block is sleeved in the shaft sleeve, the shaft sleeve and the shaft post can be fixed at a certain position through a screw, namely, the connection position between the shaft sleeve and the shaft post can be freely adjusted when the shaft sleeve is fixed through the screw, the outer wall of the shaft sleeve is also provided with a sliding sleeve through the screw, the side wall of the sliding sleeve is rotationally connected with an inclined push rod, and one end of the inclined push rod far away from the sliding sleeve is rotationally connected with the top end of the wave section 1.
When the driving mechanism 6 works, if only the sliding sleeve and the shaft sleeve are fixed, the shaft sleeve can push the sliding sleeve to descend when descending, then the inclined push rod can move downwards and push the top end of the wave section 1 to incline, otherwise, the wave section 1 is reset; if only the shaft sleeve and the shaft post are fixed, the shaft sleeve can move up and down in the movable interval 7 by the shaft post with the pushing block.
In order to rapidly realize the alternation of the wave water tank and the oscillation water flow tank, preferably, the alternation section 4 comprises a waterproof belt arranged in the water tank main body 3, the waterproof belt is attached to the inner wall of the water tank main body 3, the shape of the waterproof belt is matched with the inner wall of one end of the water tank main body 3 far away from the driving mechanism 6, the edge of one end of the waterproof belt close to the driving mechanism 6 is fixedly connected with the inner wall of the water tank main body 3, and the waterproof belt comprises a movable area 9, a bending area 10 and an adhesion fixing area 11 which are sequentially arranged;
the limiting groove 12 has been seted up to the one end inner wall that the actuating mechanism 6 was kept away from to the basin main part 3, be equipped with in the limiting groove 12 and push the piece 13, the movable region 9 setting is kept away from the one end of actuating mechanism 6 at the basin main part 3 and with push the piece 13 fixed connection, push the piece 13 and can take movable region 9 to be moved in order to make crooked district 10 crooked towards adhesion fixed region 11 one side, the one end that the actuating mechanism 6 was kept away from to the basin main part 3 is equipped with a plurality of support columns 14 with push the piece 13 fixed connection, support column 14 can push the piece 13 motion.
In order to prevent the movable region 9 from tilting and separating from the inner wall of the bottom of the water tank main body 3 during movement, it is preferable that a shaping bar 15 is installed at the connection between the movable region 9 and the bending region 10 in the limiting groove 12, and the shaping bar 15 can guide the bottom wall of the movable region 9 to be always parallel to the inner wall of the bottom of the water tank main body 3.
When the alternating of the wave water tank and the oscillation water flow tank is specifically operated, the flow is as follows:
normally, the alternating segments 4 do not move and cling to the inner wall of one end of the water tank main body 3 far away from the driving mechanism 6, water only exists in the water tank main body 3, at this time, the wave segments 1 move, and the water moves in the water tank main body 3 in a wave mode, namely, the water tank main body 3 is a wave water tank.
Once the vibration flow channel is needed, only the support column 14 is driven to push the pushing block 13 to move, then the moving pushing block 13 moves towards the adhesion fixing area 11 with the movable area 9, and when the movable area 9 moves, the shaping bar 15 guides the bottom wall of the movable area 9 to be always parallel to the inner wall of the bottom of the channel main body 3 so as to prevent the movable area 9 from tilting and separating from the inner wall of the bottom of the channel main body 3 when moving, meanwhile, along with the movement of the movable area 9, the bending area 10 is gradually bent (refer to fig. 3 in particular), the gap between the movable area 9 and the inner wall of one end of the channel main body 3 far away from the driving mechanism 6 is increased until a circulation cavity is formed, and at the moment, the two ends of the containing cavity 5 are respectively communicated with the circulation cavity and the movable interval 7 and combined to form a concave structure, so that the vibration flow channel is formed, the whole operation is quick, and if the wave channel is needed to be reset only by guiding the movable area 9.
Since a large amount of water exists in the water tank main body 3, in order to enable the movable area 9 not to push the water to move when moving, the movable area 9 is preferably provided with a water removal ball 16, and the water removal ball 16 can push the liquid to move towards the direction of the gentle section 2 by expanding the self volume;
the outer wall of one end of the water tank main body 3 far away from the driving mechanism 6 is provided with a plurality of guide cylinders 17, and each guide cylinder 17 can correspondingly accommodate each support column 14; the length of the support column 14 is greater than that of the guide cylinder 17, the support column 14 and the dewatering balls 16 are mutually communicated (the dewatering balls 16 and all the support columns 14 are communicated and all the support columns 14 can guide external air to enter), and after the support column 14 swells the volume of the support column 14, the swelled support column 14 is attached to the inner wall of the guide cylinder 17.
Under the condition that the water tank main body 3 is in a wave water tank state, no gas is introduced into the support columns 14 and the water removal balls 16, and each guide cylinder 17 correspondingly accommodates each support column 14, so that the movable area 9 is attached to the inner wall of one end, far away from the driving mechanism 6, of the water tank main body 3, and water flow does not greatly affect the movable area 9 when moving in the wave water tank.
Once the support columns 14 and the dewatering balls 16 are simultaneously introduced with the external air, the dewatering balls 16 expand their own volume and push the liquid to move towards the gentle section 2, so that the movable area 9 cannot occupy more water, all the support columns 14 are expanded, and the expanded support columns 14 are bonded with the inner wall of the guide cylinder 17 and push the movable area 9 to move gradually.
Because the support column 14 expands its volume by introducing gas to realize the purpose of pushing the movable area 9, the pushing force of the support column 14 does not necessarily meet the requirement in the operation process, so based on the above embodiment, a way of assisting in pushing the movable area 9 is provided, the side wall of the guide cylinder 17 is provided with a clamping groove 18, the side wall of the support column 14 is fixedly connected with an ejection strip 19, and the ejection strip 19 can be clamped into the clamping groove 18 after the support column 14 expands; the outer wall of one end of the water tank main body 3 far away from the driving mechanism 6 is connected with a plurality of force application columns 20 in a penetrating way, and each force application column 20 is respectively arranged corresponding to each support column 14; one end of the force application column 20 is fixedly connected with one side surface of the pushing block 13, which is far away from the driving mechanism 6, a fixed sleeve 21 is sleeved on the side wall of the other end of the force application column 20, an estimation piece 22 sleeved on the outer side wall of the force application column 20 is arranged on one end of the fixed sleeve 21, which is far away from the water tank main body 3, a limiting cylinder 23 fixedly connected with the outer wall of one end of the water tank main body 3, which is far away from the driving mechanism 6, is sleeved on the outer side of the force application column 20, an end face of the estimation piece 22 is abutted against the inner wall of one end, which is far away from the water tank main body 3, of the limiting cylinder 23, a spring column 24 (selectable spring) is mounted on the side wall of the fixed sleeve 21, one end, which is far away from the fixed sleeve 21, is abutted against the side wall of the guide cylinder 17, and when the force application column 20 slides to a certain position along the side wall of the guide cylinder 17 along the spring column 24, the spring column 24 is clamped into the clamping groove 18 to limit the force application column 20.
Further limiting the limiting cylinder 23 and the supporting column 14, wherein a sliding groove 25 for limiting the spring column 24 is formed in the side wall of the limiting cylinder 23, and the sliding groove 25 is arranged opposite to the clamping groove 18; the end of the support column 14 far away from the pushing block 13 is fixedly connected with the inner wall of one end of the guide cylinder 17 far away from the driving mechanism 6, the longitudinal section of the support column 14 is in a cylindrical shape, a quadrilateral shape or a triangle shape, and the shape of the support column 14 and the connection mode of the support column 14 and the guide cylinder 17 are arranged in order to ensure that the support column 14 can be accurately clamped into the clamping groove 18 with the ejector strip 19 after expansion, and if the support column 14 is not fixedly connected with the guide cylinder 17, the ejector strip 19 is likely to be incapable of being inserted into the clamping groove 18 in the contraction and expansion process of the support column 14.
When the water tank main body 3 is in the wave water tank state, the supporting column 14 is in the contracted state and is positioned in the guide cylinder 17, the supporting column 14 with the contracted ejection bar 19 is separated from the clamping groove 18, and simultaneously, the end part of the estimation piece 22 is clamped in the clamping groove 18, and the elastic column 24 is also in the compressed state.
(refer to fig. 6) once the air is introduced into the support column 14, the support column 14 will be clamped into the clamping groove 18 with the ejector strip 19 after being inflated, then the ejector strip 19 entering the clamping groove 18 will push out the estimation piece 22 in the clamping groove 18, then the spring column 24 will reset and push the force application column 20 and the fixed sleeve 21 together to move towards the moving area 9 along with the release of the estimation piece 22 from the clamping groove 18, namely, the force application column 20 pushes the moving area 9 to move under the action of the spring column 24.
It should be noted that: the support column 14 may be formed of two parts, wherein the part located in the guide cylinder 17 is a non-folded part, the part located outside the guide cylinder 17 is a folded part (refer to a bellows), when gas is injected, since the non-folded part is first expanded by the pressure of the movable region 9 and pushes the ejector strip 19 into the clamping groove 18 (since the pressure of the ejector strip 19 needs to be overcome, the pressure inside the non-folded part needs to be to a certain extent to push the ejector strip 19 out of the clamping groove 18, and in the process that the pressure reaches a certain extent, the dewatering ball 16 has reached the required expansion), the folded part is gradually elongated along with the movement of the movable region 9 by the force application column 20, and the elongated part is gradually filled with the gas at the same time, so that the shaking phenomenon of the movable region 9 does not occur (since the force application column 20 is easy to shake in the limiting cylinder 23, if only the force application column 20 is provided, the movable region 9 is easy to shake, and the use of the water tank is affected), in this embodiment, the pushing force of the movable region 9 comes from the support column 14 and the force application column 20.
In order to further reduce the resistance of the water received by the movable area 9 during movement, it is preferable that the surface of the gentle section 2 is provided with a plurality of liquid discharge ports 26, and a receiving chamber 27 is provided in the gentle section 2 at a position corresponding to the liquid discharge ports 26, a blocking block 28 capable of blocking all the liquid discharge ports 26 is movably connected in the receiving chamber 27, the receiving chamber 27 is communicated with the water removal ball 16, and when the gas is introduced into the water removal ball 16, the blocking block 28 moves in the receiving chamber 27 and releases the blocking of all the liquid discharge ports 26.
A plurality of pulling members 29 (optional tension springs, in a relaxed state when the plugging block 28 is not moved) fixedly connected with the inner wall of the accommodating chamber 27 are arranged at one end of the plugging block 28 close to the water removal ball 16, one end of the accommodating chamber 27 close to the water removal ball 16 is communicated with the water removal ball 16, a plurality of alignment ports 30 are formed in the surface of the plugging block 28, each alignment port 30 is respectively and correspondingly arranged with each liquid drain port 26, and the width of the plugging block 28 is equal to that of the accommodating chamber 27.
When the gas is injected to enable the dewatering ball 16 to gradually reach the required expansion degree, the gas also enters the accommodating chamber 27, then the gas entering the accommodating chamber 27 pushes the blocking block 28 to slide along the accommodating chamber 27 until the blocking of all the liquid outlets 26 is released, at this time, each alignment port 30 is respectively communicated with each liquid outlet 26, and then the water in the water tank main body 3 enters the accommodating cavity 5, so that the resistance of the water received by the movable area 9 during movement is reduced.
The distance from the inner wall of the limiting groove 12 to the pushing block 13 is gradually reduced from the side far away from the driving mechanism 6 to the side close to the driving mechanism 6. The reason for this is that once the pushing block pushes water to move in the concave structure, the water flow easily impacts on the surface of the active area 9, if the limiting groove 12 is in a horizontal state, the area where the limiting groove 12 is located is easy to accumulate water, and the accumulated water is easy to flow out when the pushing block is set to different heights.
The wave section 1 comprises a limiting cover 31 arranged in the movable space 7, the pushing block is arranged in the limiting cover 31, one side of the limiting cover 31 close to the gentle section 2 is provided with a deflection block 8 in sealing connection with the gentle section 2, and a excluder 32 is arranged between the deflection block 8 and the limiting cover 31.
The limiting cover 31 can be made of rubber materials, so that the pushing block can fully push water flow, the deflection block 8 can also be made of rubber materials, meanwhile, the rubber at the joint between the deflection block 8 and the gentle section 2 is set to be loose, so that the deflection block 8 can deflect normally, and when the deflection block 8 deflects, the isolating strips 32 can be stretched, so that water flow cannot enter between the deflection block 8 and the limiting cover 31 or on the surface of the pushing block along the deflection block 8.
The specific working flow of the invention is as follows:
the present invention is specifically directed to the alternate use of a wave trough and an oscillating trough, and therefore will be described below in terms of two trough states.
When the wave water tank is in the wave water tank, the blocking block 28 can block all the liquid drain ports 26, the alternating sections 4 do not move and cling to the inner wall of one end, far away from the driving mechanism 6, of the water tank main body 3, water only exists in the water tank main body 3, no air is introduced into the supporting columns 14 and the water removal balls 16, each guiding cylinder 17 correspondingly accommodates each supporting column 14, meanwhile, the ejector strip 19 is separated from the clamping groove 18 by the contracted supporting column 14, the end of the estimating piece 22 is clamped in the clamping groove 18, the elastic column 24 is in a compressed state, then the driving mechanism 6 is started, at the moment, the top end of the wave section 1 is pushed by the driving mechanism 6 and is inclined and deflected towards the alternating sections 4 by a set angle through the bottom end of the wave section 1, and at the moment, the top end deflection of the wave section 1 is repeatedly guided, so that the liquid can move in the water tank main body 3 in a wave mode.
State transition process: the outside air injection device is used for injecting air, namely the air enters the support column 14, the water removal ball 16 and the accommodating chamber 27 at the same time;
once the air is introduced into the support column 14, the support column 14 will be clamped into the clamping groove 18 with the ejector strip 19 after being inflated, then the ejector strip 19 entering the clamping groove 18 will push out the estimation piece 22 in the clamping groove 18, and as the estimation piece 22 is separated from the clamping groove 18, the spring column 24 will reset and push the force application column 20 and the fixed sleeve 21 to move together towards the moving area 9, namely, the force application column 20 pushes the moving area 9 to move under the action of the spring column 24. The support column 14 may be formed of two parts, wherein the part in the guide cylinder 17 is a non-folded part, the part outside the guide cylinder 17 is a folded part (refer to a bellows), when gas is injected, the folded part is gradually elongated along with the movement of the force application column 20 pushing the movable region 9, and the elongated part is gradually filled along with the injection of the gas, so that the movable region 9 does not shake, i.e. a circulation cavity is formed, due to the fact that the pressure in the non-folded part needs to reach a certain degree to push the push-out piece 22 out of the clamping groove 18, and the dewatering ball 16 reaches a required expansion degree in the process of reaching a certain degree;
when the gas is injected to gradually expand the dewatering ball 16 to a required expansion degree, the gas also enters the accommodating chamber 27, and then the gas entering the accommodating chamber 27 pushes the blocking block 28 to slide along the accommodating chamber 27 until the blocking of all the liquid outlets 26 is released, at this time, each alignment port 30 is respectively and correspondingly communicated with each liquid outlet 26, then water in the water tank main body 3 can enter the accommodating cavity 5, so that the resistance of the water received by the movable area 9 during movement is reduced, and after the gas injection is finally completed, the two ends of the accommodating cavity 5 are respectively communicated with the circulation cavity and the movable interval 7 and combined to form a concave structure, namely, an oscillating water tank is formed.
That is, the water removal ball 16 and the accommodating chamber 27 are firstly inflated, after the water removal ball 16 is inflated to a required expansion degree, the plugging block 28 in the accommodating chamber 27 can release the plugging of all the liquid drain ports 26, and then the support column 14 can cooperate with the force application column 20 to push the movable region 9 to move.
Use of an oscillating gutter: the liquid can move in the concave structure by guiding the pushing block to move along the direction vertical to the containing cavity 5 through the driving mechanism 6.
