Description

Technical Field

[0001] This invention relates to the field of constant pressure pump protection technology, specifically to a constant pressure pump protection device that is easy to install. Background Technology

[0002] The development and research of constant pressure pumps is a new type of high-efficiency and energy-saving product that emerged against this background. With the acceleration of urbanization and the increase in national investment in drinking water safety, the demand for pumps in municipal and rural water supply projects is also increasing. At present, pressure stabilizing devices composed of centrifugal pumps and frequency conversion systems are commonly used in the international and domestic markets. They are expensive, with high initial installation costs and high operation and maintenance costs. For rural water supply projects with relatively insufficient investment, such costs are even unacceptable. Constant pressure pumps fundamentally eliminate the drawback of pump outlet pressure changing with flow rate.

[0003] A search revealed Chinese patent CN209761825U, which discloses a protective device for a constant pressure pump that is easy to install. The device includes a lower base plate, a connecting strip, a reinforcing plate, an upper base plate, a motor base, a motor, a connecting frame, a pump cover, a pump body, an auxiliary seat, a first connector, a second connector, a sleeve cover, a cover cavity, an adjustable support and reinforcing auxiliary frame structure, an extended protective connecting sleeve structure, and a sealing connecting plate frame structure. The connecting strip is welded between the lower and upper base plates. The reinforcing plates are welded to the left and right sides of the front and rear surfaces of the connecting strip, and are also welded to the lower and upper base plates respectively. The advantages of this invention are: by adjusting the support and reinforcing auxiliary frame structure, its length can be adjusted, facilitating both support and storage; the extended protective connecting sleeve structure extends the length of the protective device for constant pressure pumps, making it suitable for protecting constant pressure pumps of different sizes.

[0004] The aforementioned protective devices only provide a coarse-grained wrapping of the pump body using a sleeve and sealing disc, but they do not design independent isolation structures for critical vulnerable parts of the constant pressure pump, such as the wiring terminals. Furthermore, the sealing sleeve of the extended protective connecting sleeve structure is a fixed-length PVC plastic sleeve, which cannot be flexibly extended or adjusted in angle according to actual operating conditions. When there are sudden changes in pump body dimensions or pipeline misalignment, the installation error is significant, and the sealing sleeve may fail due to excessive stretching or twisting, or even tear. Therefore, this invention designs an easy-to-install protective device for constant pressure pumps to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a constant pressure pump protection device that is easy to install, solving the problem in the prior art that it is impossible to flexibly extend or adjust the angle according to actual working conditions.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] An easy-to-install constant pressure pump protection device includes:

[0008] The base has a slidably connected transverse mechanism on its top for installing and removing the constant pressure pump.

[0009] A clamping mechanism, mounted on top of the traverse mechanism, is used to protect the bottom area of ​​the constant pressure pump.

[0010] The working mechanism is installed on the top of the base and is used to protect the top area of ​​the constant pressure pump. The working mechanism includes a lifting component, an adjusting component, and a heat dissipation component. The lifting component is installed on the top of the base and is used for coarse adjustment of the protection position of the constant pressure pump. The adjusting component is installed on the top of the lifting component and is used for fine adjustment of the protection position of the constant pressure pump. The heat dissipation component is installed in the inner cavity of the lifting component and is used for heat dissipation during the use of the constant pressure pump.

[0011] Preferably, the lifting assembly includes a mounting plate fixedly connected to the top of the base, a bidirectional lead screw rotatably connected between the mounting plates on the front and back sides, a mounting block threaded to the outer ring of the bidirectional lead screw, and a connecting plate hinged to the top of the mounting block, the connecting plates being rotatably connected by pins and arranged in an X-shape, a moving block hinged to the top of the connecting plate, a lifting plate slidably connected to the top of the moving block, a telescopic rod connecting the lifting plate and the mounting plate, and a linkage assembly installed on the back of the mounting plate for synchronous rotation of the bidirectional lead screws on both sides.

[0012] Preferably, the linkage assembly further includes a dual-axis motor installed in the inner cavity of the mounting plate. The front output shaft of the dual-axis motor is fixedly connected to the bidirectional lead screw located on the right side. The rear output shaft of the dual-axis motor is fixedly connected to a linkage rod. The bidirectional lead screw located on the left side passes through the mounting plate and extends to the back of the mounting plate. The back of both the bidirectional lead screw and the linkage rod located on the left side are fixedly connected to synchronous pulleys. The synchronous pulleys are connected by a belt. A tensioning pulley is also installed on the back of the mounting plate for the normal operation of the belt.

[0013] As can be seen from the above technical solution, after the dual-axis motor starts, its front output shaft directly drives the right-side bidirectional lead screw to rotate; the rear output shaft synchronously drives the left-side bidirectional lead screw through the linkage rod, synchronous pulley, and belt, ensuring that the movements of both sides are completely consistent; when the bidirectional lead screw rotates, the mounting blocks slide towards or away from each other on the fixed rod, and the X-shaped connecting plate retracts or expands accordingly, pushing the moving block to slide up and down along the limiting groove, thereby realizing the rapid lifting and lowering of the lifting plate and completing the coarse adjustment of the protective cover height. The telescopic rod provides lateral support during this process to prevent swaying.

[0014] Preferably, a fixing rod is fixedly connected between the mounting plates, the mounting block is slidably sleeved on the outer ring of the fixing rod, a limit groove is opened at the bottom of the lifting plate, a limit block is fixedly connected to the top of the moving block, and the limit block is slidably connected in the inner cavity of the limit groove.

[0015] Preferably, the adjusting assembly includes an adjusting frame fixedly connected to the top of the lifting plate, a lifting frame slidably connected to the inner cavity of the adjusting frame, a rack fixedly connected to the front of the lifting frame, a fixing block fixedly connected to the front of the adjusting frame, a driving rod installed between the fixing block and the adjusting frame, a driving crank fixedly connected to the top of the driving rod, a driving bevel gear installed on the outer ring of the driving rod, a driven rod installed in the inner cavity of the adjusting frame, a driven bevel gear installed on the outer ring of the driven rod, the driving bevel gear and the driven bevel gear meshing with each other, and a gear installed on the outer ring of the driven rod meshing with the rack.

[0016] As can be seen from the above technical solution, manually rotating the drive handle causes the drive rod to drive the drive bevel gear to rotate, and the driven rod that meshes with the driven bevel gear rotates synchronously; the gear drives the rack to move the lifting frame up and down in millimeters within the adjusting frame until the lower edge of the lifting frame is precisely in contact with the top contour of the constant pressure pump, thereby achieving precise positioning and avoiding overpressure or excessive gap.

[0017] Preferably, the heat dissipation component includes heat dissipation fans installed on both sides of the lifting frame, and the heat dissipation component also includes heat dissipation holes opened in the inner cavity of the lifting frame, the heat dissipation holes being distributed in multiple sets of matrix arrays.

[0018] Preferably, the bottom of the lifting frame is provided with a buffer groove, a buffer plate is rotatably connected in the inner cavity of the buffer groove, a buffer rod is installed at the top of the inner cavity of the lifting frame, a roller is installed at the bottom of the buffer rod, and a buffer spring is installed on the outer ring of the buffer rod.

[0019] As can be seen from the above technical solution, the cooling fans on both sides of the lifting frame continuously send air to the surface of the pump body, and the hot air is quickly discharged through the matrix-arranged heat dissipation holes to maintain the pump body at a safe operating temperature; if the pump body vibrates, the buffer plate rotates slightly in the buffer groove, the rollers stick to the pump shell and roll, and the buffer spring outside the buffer rod is compressed and rebounded synchronously to absorb the impact energy and prevent damage or noise caused by rigid collision.

[0020] Preferably, the lateral movement mechanism includes a movable plate slidably connected to the top of the base, a handle fixedly connected to the front of the movable plate, a groove formed on the top of the base, and a slider fixedly connected to the bottom of the movable plate. The slider is slidably connected in the inner cavity of the groove for limiting the movement of the movable plate.

[0021] Preferably, the clamping mechanism includes a clamping frame fixedly connected to the top of the movable plate, a support pad fixedly connected to the bottom of the inner cavity of the clamping frame, a support seat fixedly connected to the inner wall of the clamping frame, a threaded hole opened in the inner cavity of the clamping frame, a threaded rod threadedly connected to the inner cavity of the threaded hole, a clamping crank installed on the outer ring of the threaded rod, a movable seat installed on one side of the threaded rod, and the threaded rod and the movable seat are rotatably connected by a bearing.

[0022] Preferably, protective pads are installed in the inner cavities of the support base and the movable base, and limit rods are installed between the inner wall of the clamping frame and the movable base. Two sets of limit rods are provided and are telescopic.

[0023] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0024] 1. The present invention forms an openable and closable independent protective chamber at the bottom of the pump body and a floating protective cover that conforms to the pump contour at the top by a hierarchical combination of clamping mechanism and lifting and adjusting components. Key parts such as wiring terminals are partially surrounded and isolated from the external environment, achieving precise protection and avoiding the problems of heat dissipation obstruction and maintenance inconvenience caused by traditional overall wrapping.

[0025] 2. In this invention, the lower edge of the lifting frame can be lowered with millimeter-level precision by adjusting the components, directly pressing against the top of the junction box to form a partially sealed space. Combined with the flexible contact of the buffer pad and rollers, it not only isolates moisture and dust, but also avoids rigid pressure damage to the terminals, achieving independent and repeatedly removable sealed protection for the terminals.

[0026] 3. In this invention, the lifting component achieves a wide range of stepless lifting through a bidirectional lead screw and an X-shaped hinge mechanism, while the adjusting component completes a small range of fine displacement through a gear-rack pair. The two components are superimposed to form two degrees of freedom: "coarse adjustment" and "fine adjustment". The protective height and angle can be adjusted in real time according to the pump body height and pipeline offset, replacing the traditional fixed-length sleeve. The lateral movement mechanism allows the pump body to slide out and in horizontally as a whole, and the clamping mechanism adaptively clamps pump bodies of different widths through a combination of threads and limit rods.

[0045] The working principle of this invention embodiment is as follows: when the coarse adjustment height is close to the target position, manually rotate the drive handle to make the drive rod 405 drive the drive bevel gear 406 to rotate, and the driven rod 407, which meshes with the driven bevel gear 408, rotates synchronously; the gear 409 drives the rack 403 to drive the lifting frame 402 to make millimeter-level up and down displacements within the adjustment frame 401 until the lower edge of the lifting frame 402 precisely fits the top contour of the constant pressure pump.

[0046] Example 3;

[0047] Please see Figures 1-9 In this embodiment of the invention, the transverse mechanism 1 includes a movable plate 102 slidably connected to the top of the base 101. A handle 103 is fixedly connected to the front of the movable plate 102. A groove 104 is provided on the top of the base 101. A slider 105 is fixedly connected to the bottom of the movable plate 102. The slider 105 is slidably connected in the inner cavity of the groove 104 for limiting the movement of the movable plate 102.

[0048] The clamping mechanism 2 includes a clamping frame 201 fixedly connected to the top of the movable plate 102. A support pad 202 is fixedly connected to the bottom of the inner cavity of the clamping frame 201. A support seat 203 is fixedly connected to the inner wall of the clamping frame 201. A threaded hole 204 is opened in the inner cavity of the clamping frame 201. A threaded rod 205 is threadedly connected to the inner cavity of the threaded hole 204. A clamping handle 206 is installed on the outer ring of the threaded rod 205. A movable seat 207 is installed on one side of the threaded rod 205. The threaded rod 205 and the movable seat 207 are rotatably connected by a bearing. A protective pad 208 is installed in the inner cavity of the support seat 203 and the movable seat 207. A limit rod 209 is installed between the inner wall of the clamping frame 201 and the movable seat 207. Two sets of limit rods 209 are provided and are telescopic.

[0049] The working principle of this invention embodiment is as follows: the rotating clamping handle 206 is rotated, the threaded rod 205 is pushed into the threaded hole 204, and the moving seat 207 is driven to slide smoothly to the other side of the pump body; two sets of telescopic limit rods 209 ensure that the moving seat 207 does not deviate until the protective pads 208 on both sides are evenly pressed against the pump body, and the bottom is fixed.

[0050] Working principle: The operator first holds the handle 103 and pulls the moving plate 102 outward along the slide groove 104 through the transverse mechanism 1, so that the clamping frame 201 is fully exposed. Then, the constant pressure pump is gently placed on the support pad 202, so that one side of the pump body is first pressed against the fixed support seat 203, and then the clamping handle 206 is rotated. The threaded rod 205 is pushed into the threaded hole 204, which drives the moving seat 207 to slide smoothly to the other side of the pump body. Two sets of telescopic limit rods 209 ensure that the moving seat 207 does not tilt, until the protective pads 208 on both sides are evenly pressed against the pump body, and the bottom is fixed.

[0051] After the dual-axis motor 501 starts, its front output shaft directly drives the right-side bidirectional lead screw 302 to rotate; the rear output shaft synchronously drives the left-side bidirectional lead screw 302 through the linkage rod 502, synchronous pulley 503, and belt 504, making the movement of both sides completely consistent; when the bidirectional lead screw 302 rotates, the mounting block 303 slides towards or away from each other on the fixed rod 308, and the X-shaped connecting plate 304 retracts or expands accordingly, pushing the moving block 305 to slide up and down along the limiting groove 309, thereby realizing the rapid lifting and lowering of the lifting plate 306 and completing the coarse adjustment of the protective cover height. The telescopic rod 307 provides lateral support during this process to prevent swaying.

[0052] Once the coarse adjustment height is close to the target position, manually rotate the drive handle to make the drive rod 405 drive the drive bevel gear 406 to rotate, and the driven rod 407, which meshes with the driven bevel gear 408, rotates synchronously; the gear 409 drives the rack 403 to make the lifting frame 402 move up and down in millimeters within the adjusting frame 401 until the lower edge of the lifting frame 402 is precisely in contact with the top contour of the constant pressure pump, achieving fine positioning and avoiding overpressure or excessive gap.

[0053] During the operation of the constant pressure pump, the cooling fans 601 on both sides of the lifting frame 402 continuously deliver air to the surface of the pump body. The hot airflow is quickly discharged through the matrix-arranged heat dissipation holes 602 to maintain the pump body at a safe operating temperature. If the pump body vibrates, the buffer plate 411 rotates slightly in the buffer groove 410, the roller 413 is pressed against the pump casing and rolls, and the buffer spring 414 outside the buffer rod 412 is compressed and rebounded synchronously to absorb the impact energy and prevent damage or noise caused by rigid collision.

[0054] After stopping the machine, rotate the clamping handle 206 in the opposite direction to release the pump body from the moving seat 207; pull the handle 103 again to move the entire horizontal movement mechanism 1 outward, and the constant pressure pump can be easily lifted out; then reverse the dual-axis motor 501 to reset the lifting component 3 to the lowest position, making room for the next installation.

[0055] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
