Description

Technical Field

[0001] This utility model relates to the field of water storage equipment technology, and in particular to a quantitative water storage tank. Background Technology

[0002] Water storage tanks, as common water storage containers, are widely used in industrial and agricultural production, daily life, and emergency water supply. To prevent water tank overflow and achieve automatic water replenishment, traditional water storage tanks usually have a float valve installed at the water inlet pipe. Utilizing the principle of buoyancy, when the water level rises to a certain height, it causes the float to rise, which in turn drives the valve to close, thereby maintaining the water level in the tank at a preset level.

[0003] However, in existing technical solutions, float valves are typically fixed at a specific height inside the water tank or directly fixed to the end of a rigid inlet pipe. This means that once the equipment is installed, the inlet water level of the tank is fixed, and its maximum single-use capacity is also constant. In actual use, users often face diverse water needs, such as scenarios requiring precise drug preparation, limiting the maximum single-use volume, or adjusting the stored water volume according to seasonal changes. Such fixed-level water tanks lack flexibility. If users want to change the stored water volume, they often need to open the tank cover and use tools to access the tank to disassemble or reposition the float valve. This process is not only cumbersome and laborious but also easily contaminates the water inside the tank and makes precise level adjustment difficult. Furthermore, some existing simple water storage devices often use direct stopcocks or external valves for drainage control, requiring direct contact with the outlet or relying on complex piping systems. They lack an integrated solution that can flexibly adjust the inlet water volume while controlling quantitative discharge through a simple mechanical structure.

[0004] Therefore, this utility model proposes a quantitative water storage tank to overcome the shortcomings of the prior art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a quantitative water storage tank, which aims to improve the structural defects of existing water storage tanks, which usually have a fixed inlet water cut-off level and cannot flexibly adjust the water storage volume according to actual water demand, and whose drainage mechanism is complicated to operate or has poor sealing, making it difficult to achieve quantitative water storage and controllable discharge.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a quantitative water storage tank, comprising: a tank body, an installation cover on the top of the tank body, a water inlet pipe communicating with the interior of the tank body; and an adjustment assembly disposed on the side wall of the tank body and a pull rope assembly disposed inside the tank body.

[0007] The adjustment assembly includes an adjustment rod that slides against the outer wall of the housing. The adjustment rod is fixedly connected to a support rod that passes through the interior of the housing. An inlet valve connected to the inlet pipe is installed at the end of the support rod away from the adjustment rod. A float valve for controlling the opening and closing of the inlet valve is connected to the bottom of the inlet valve. The relative height of the float valve inside the housing can be changed by sliding the adjustment rod.

[0008] Furthermore, the pull rope assembly includes a pull rope shaft rotatably mounted on the mounting cover and a counterweight block that cooperates to seal the drain outlet at the bottom of the box. A traction rope is connected between the pull rope shaft and the counterweight block. The traction rope passes around a pulley rotatably mounted on the inner wall of the box. By rotating the pull rope shaft, the counterweight block can be pulled away from the drain outlet.

[0009] Preferably, the adjustment assembly further includes an adjustment plate that fits against the outer wall of the housing. The adjustment plate is located outside the adjustment rod and is pressed and fixed to the adjustment rod by bolts. The vertical position of the support rod and the float valve is locked by the friction between the adjustment plate and the outer wall of the housing or by a limiting structure.

[0010] Preferably, multiple adjustment plates are arranged vertically, and the multiple adjustment plates are arranged in sequence and pressed against the surface of the adjustment rod to enhance the stability of fixing the position of the adjustment rod.

[0011] Preferably, the pull rope assembly further includes a guide plate fixed to the inner wall of the box, the pulley is rotatably connected to the side of the guide plate facing the center of the box, and the guide plate extends to the outer periphery of the pulley to prevent the traction rope from disengaging from the groove of the pulley.

[0012] Preferably, a limiting block is fixed on the rope segment between the pulley and the counterweight of the traction rope. The outer dimensions of the limiting block are larger than the rope clearance between the pulley and the guide plate, which is used to limit the maximum distance the counterweight is pulled away from the drain outlet.

[0013] Preferably, the counterweight is in the shape of a frustum cone, with the smaller diameter end of the counterweight facing downwards and inserted into the drain outlet at the bottom of the box, thereby sealing the drain outlet by the weight of the counterweight and the suction force of the water flow.

[0014] Preferably, the outer wall of the housing is provided with a vertically extending groove, and part of the adjusting rod is slidably embedded in the groove to limit the movement trajectory of the adjusting rod to be perpendicular to the horizontal plane.

[0015] Preferably, the inlet valve has a downwardly extending valve stem, and the float valve is fixed to the end of the valve stem. When the water level in the tank rises above the float valve, the buoyancy generated by the float valve pushes the valve stem upward to close the inlet valve.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problem of fixed water inlet cut-off level and difficulty in flexibly adjusting water storage volume according to actual needs by setting an adjustable rod that can slide up and down on the outer wall of the tank and linking it with the internal float valve, and cooperating with the locking and fixing structure of the adjusting plate. It achieves the effect of physically adjusting the water storage threshold from the outside without opening the inside of the tank, and meeting the quantitative water storage needs under different working conditions. 2. This utility model solves the problems of inconvenient drainage operation or unreliable sealing and resetting of traditional simple water storage tanks by setting up a pull rope assembly, pulley guide and a counterweight block in the shape of a truncated cone. It achieves the effect of opening drainage by pulling externally, and automatically returning to its original position and tightly blocking the drain outlet by the weight of the counterweight block and the suction force of the water flow after releasing the hand. It realizes drainage control that is convenient to operate, does not require contact with water and has good sealing performance. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figures 1-5 The present invention provides an embodiment of a quantitative water storage tank, comprising a tank body 1 for containing water and a mounting cover 2 covering the top of the tank body 1. The tank body 1 is a hollow container structure with a certain volume. The mounting cover 2 securely seals the top opening of the tank body 1 by means of bolt connection or snap-fit ​​connection to prevent external impurities from falling in. An adjustment component 4 for physically adjusting the water level is provided on the side wall of the tank body 1. A pull rope component 5 for controlling the opening and closing of the bottom drain outlet is provided inside and at the top of the tank body 1. In order to replenish the water source into the tank body 1, a water inlet pipe 3 is provided that connects to the inside of the tank body 1. One end of the water inlet pipe 3 is connected to the external water supply network, and the other end passes through the side wall of the tank body 1 or the mounting cover 2 to enter the interior.

[0021] The adjusting component 4, as the core adjusting mechanism of this technical solution, includes an adjusting rod 405 that slides against the outer wall of the housing 1. To ensure the verticality and stability of the adjusting path, a vertically extending groove is provided on the outer wall of the housing 1. Part of the adjusting rod 405 is slidably embedded in the groove, thereby limiting the movement trajectory of the adjusting rod 405 to be perpendicular to the horizontal plane. The adjusting rod 405 passes through the side wall of the housing 1 and is fixedly connected to a support rod 401 extending into the housing 1. An inlet valve 403 connected to the inlet pipe 3 is installed at the end of the support rod 401 away from the adjusting rod 405. The bottom of the water valve 403 is vertically connected to a float valve 402 for controlling the opening and closing of the water inlet valve 403. By sliding the adjusting rod 405 up and down on the outer wall of the housing 1, it can directly drive the rigidly connected support rod 401, the water inlet valve 403 and the float valve 402 to move synchronously, thereby changing the relative height position of the float valve 402 in the housing 1. In addition, in order to fix the adjusted position, the adjusting assembly 4 also includes an adjusting plate 404 that fits against the outer wall of the housing 1 and is located outside the adjusting rod 405. The position is locked by the cooperation of the adjusting plate 404 and the adjusting rod 405.

[0022] The pull rope assembly 5 constitutes the drainage control logic of the device, including a pull rope shaft 501 rotatably mounted on the mounting cover 2 and a counterweight 505 that cooperates to seal the drain outlet at the bottom of the housing 1. The pull rope shaft 501 serves as the external operating end, and the counterweight 505 serves as the internal actuating end. The two are flexibly connected by a traction rope. One end of the traction rope is wound and connected to the pull rope shaft 501, and the other end extends downward and connects to the counterweight 505. To ensure that the transmission path of the traction rope is accurate and avoids the interior of the housing 1... To prevent interference from other components, the rope assembly 5 also includes a guide plate 502 fixed to the inner wall of the box 1 and a pulley 503 rotatably connected to the guide plate 502 on the side facing the center of the box 1. The traction rope passes around the pulley 503 and is connected to the counterweight 505. A limit block 504 is also fixed on the rope section of the traction rope located between the pulley 503 and the counterweight 505. By rotating the rope shaft 501, the traction rope can be wound up, thereby pulling the counterweight 505 to overcome its own weight and water pressure and detach from the drain outlet to achieve a quantitative water discharge. The adjusting rod 405 in the adjusting assembly 4 has a sliding feature adapted to the outer wall structure of the housing 1. In order to achieve stable guidance, a T-shaped guide groove extending in the vertical direction is opened on the outer wall of the housing 1. Part of the structural shape of the adjusting rod 405 matches the T-shaped guide groove and is embedded therein, thereby restricting the adjusting rod 405 to only move in the vertical direction. The adjusting rod 405 passes horizontally through the side wall of the housing 1 and is fixedly connected to or integrally formed with the support rod 401 located inside the housing 1. The support rod 401 extends to the central area of ​​the housing 1 as a cantilever structure. The water inlet valve 403 is fixedly installed at the end of the support rod 401. The water inlet pipe 3 is connected to the water inlet of the water inlet valve 403 through a hose or telescopic pipe to adapt to the position change of the water inlet valve 403 when it moves up and down with the support rod 401.

[0023] To lock the position of the adjusting rod 405, the adjusting assembly 4 also includes at least one adjusting plate 404. The adjusting plate 404 is located on the side of the adjusting rod 405 outside the housing 1. The adjusting plate 404 has a through hole, through which fasteners such as bolts pass and are threaded to the adjusting rod 405 or the slider nut embedded in the wall of the housing 1. By tightening the bolt, the adjusting plate 404 is tightly pressed against the surface of the adjusting rod 405. The friction or mechanical interlocking force generated between the adjusting plate 404, the adjusting rod 405 and the outer wall of the housing 1 is used to lock the adjusting rod 405 at a preset height. This tight and fixed fit ensures that the water inlet valve 403 maintains a constant height position when subjected to water flow impact or buoyancy, preventing water level deviation due to loosening of the adjusting mechanism.

[0024] Meanwhile, a float valve 402 is connected below the inlet valve 403. The float valve 402 is connected to the valve core inside the inlet valve 403 via a connecting rod or valve stem. As a water level sensing element, when the water level in the tank 1 rises and contacts and submerges the float valve 402, the buoyancy generated by the float valve 402 pushes the valve core of the inlet valve 403 upward through the connecting rod until the water inlet channel is completely closed. Since the adjusting rod 405 determines the initial installation height of the inlet valve 403 and the float valve 402, the water inlet cut-off level can be linearly changed by changing the vertical position of the adjusting rod 405 on the tank 1, thereby realizing stepless adjustment of the water storage capacity. In a preferred embodiment, in order to enhance the stability of the adjusting component 4 after it is fixed and to prevent accidental slippage, multiple adjusting plates 404 are provided in the vertical direction, such as two or three adjusting plates 404 arranged closely in sequence and pressed against the surface of the adjusting rod 405. By increasing the contact area and the number of locking points, the force is distributed, thereby ensuring that the adjusting rod 405 will not fall or shift when it bears the weight of the inlet valve 403 and the float valve 402.

[0025] As another preferred embodiment, in order to prevent the traction rope from coming out of the groove of the pulley 503 during frequent pulling or slackening and causing jamming, the guide plate 502 is designed with an inverted L-shaped or U-shaped frame structure. The guide plate 502 not only provides a rotation shaft support for the pulley 503, but the end structure of the guide plate 502 also extends to cover the top or side of the outer periphery of the pulley 503, thereby forming a closed or semi-closed rope guide channel between the pulley 503 and the guide plate 502. The gap of the rope guide channel is smaller than the diameter of the traction rope, ensuring that the traction rope is always confined within the groove of the pulley 503.

[0026] In another preferred embodiment, in order to precisely control the opening stroke of the drainage mechanism and prevent the counterweight 505 from being pulled up excessively and failing to return to its accurate position, a limiting block 504 is fixed on the rope segment between the pulley 503 and the counterweight 505. The limiting block 504 is a spherical, cylindrical or block-shaped structure, and the outer dimensions of the limiting block 504 are significantly larger than the gap between the pulley 503 and the guide plate 502 through which the traction rope passes. When the traction rope is pulled upward, the limiting block 504 rises with the traction rope until it abuts against the lower surface of the pulley 503 or the guide plate 502, thereby forming a mechanical hard limit and restricting the counterweight 505 from continuing to rise.

[0027] As another preferred embodiment, in order to ensure the sealing performance when the drain is closed, the counterweight 505 is in the shape of a frustum or an inverted frustum. The small diameter end of the counterweight 505 faces downward and is inserted into the drain at the bottom of the box 1. The large diameter end is located above and connected to the traction rope. Utilizing the principle of conical surface engagement, the counterweight 505 can automatically find its center and fit tightly against the edge of the drain under its own weight and the suction force of the water flow, effectively blocking the water flow.

[0028] As another preferred embodiment, the inlet valve 403 has a downwardly extending valve stem, and the float valve 402 is fixed to the end of the valve stem. When the water level in the tank 1 rises and submerges the float valve 402, the buoyancy generated by the float valve 402 pushes the valve stem upward to drive the valve core inside the inlet valve 403 to close. This rigid connection method is direct and responsive.

[0029] Working Principle: When it is necessary to control and adjust the water storage capacity of this equipment, the operator loosens the fasteners of the adjusting plate 404 in the adjusting assembly 4, and then manually operates the adjusting rod 405 to slide vertically along the groove on the outer wall of the tank 1. Since the adjusting rod 405 is rigidly connected to the support rod 401, the inlet valve 403, and the float valve 402 inside the tank 1, the vertical displacement of the adjusting rod 405 directly drives the float valve 402 to synchronously change its relative height position inside the tank 1. After the float valve 402 is adjusted to the target water level, the bolts on the adjusting plate 404 are tightened again. The adjusting plate 404 tightly presses and locks the adjusting rod 405 to the outer wall of the tank 1, thereby fixing the relative position of the support rod 401 and the float valve 402, so that the float valve 402 maintains a stable operating reference plane during operation.

[0030] During the water intake process, external water enters the inlet valve 403 through the inlet pipe 3 and flows into the tank 1. As the water level in the tank 1 gradually rises, when the water level contacts and submerges the float valve 402, the buoyancy generated by the float valve 402 pushes the valve stem of the inlet valve 403 to move upward, thereby closing the inlet valve 403 and stopping the water intake. At this time, the water level in the tank 1 is the set water storage volume, thus realizing the controllable adjustment of the water intake height and the water replenishment threshold.

[0031] When it is necessary to drain the water stored in the tank 1, the operator or an external mechanism pulls the pull rope shaft 501 of the pull rope assembly 5. The pull rope shaft 501 winds the traction rope, and guided by the guide plate 502 and the pulley 503, pulls the bottom counterweight 505 upward out of the drain outlet. When the counterweight 505 is pulled away from the drain outlet, the channel at the bottom of the tank 1 opens, and the stored water begins to drain out. During this process, the limit block 504 moves upward with the traction rope and eventually abuts against the pulley 503 or the guide plate 502 to prevent the counterweight 505 from being pulled too far.

[0032] When the pulling is stopped and the rope shaft 501 is released, the pulling force disappears, and the counterweight 505 automatically falls back to its original position under its own weight. At the same time, with the assistance of the suction force generated by the water flow at the drain outlet, the conical surface of the counterweight 505 tightly fits and blocks the drain outlet, preventing the water from flowing out further. After the drainage is completed, the automatic sealing reset is achieved, realizing stable control and quantitative discharge of the water discharge process.
