Description

Technical Field

[0001] This utility model relates to the field of earthquake-resistant installation components, and in particular to an earthquake-resistant sewage pump installation mechanism. Background Technology

[0002] In many fields such as municipal drainage, industrial wastewater treatment, agricultural irrigation, and construction, sewage pumps are key fluid transport equipment, and their stable operation is directly related to the working efficiency and safety of the entire system.

[0003] Existing technologies typically employ simple vibration damping measures such as spring dampers and rubber pads for the installation and fixation of sewage pumps. However, traditional vibration damping methods have significant limitations: while spring dampers can buffer vertical vibrations to a certain extent, they are not effective at suppressing horizontal and torsional vibrations; the vibration damping performance of rubber pads is greatly affected by factors such as material hardness and temperature, and they are prone to aging and elasticity decay under long-term high-frequency vibration, making them difficult to adapt to complex vibration environments; moreover, these traditional structures mostly rely on a single vibration damping principle, which cannot effectively cope with the multi-directional and multi-frequency composite vibrations generated during the operation of sewage pumps, resulting in unsatisfactory vibration damping effects and failing to meet the requirements of modern engineering for the high stability and long service life of sewage pumps.

[0004] To address the shortcomings of the aforementioned technologies, we propose a seismic-resistant sewage pump installation mechanism. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a seismic-resistant sewage pump installation mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An anti-vibration sewage pump installation mechanism includes a mounting base, a sewage pump connection base is disposed on the top of the mounting base, and four sets of shock-absorbing mechanisms are disposed at the bottom of the sewage pump connection base. Each shock-absorbing mechanism includes a sliding rod and a sleeve. A rubber valve plate is fixedly installed at the bottom of the sliding rod. The rubber valve plate slides against the bottom of the sleeve. A spring is fixedly connected between the bottom of the rubber valve plate and the bottom of the sleeve. An opening is provided on the side wall of the bottom of the sleeve. A thick rubber ball is fixedly installed inside the opening. The sleeve and the thick rubber ball are filled with heavy oil.

[0008] Furthermore, an upper ball is fixedly connected to the upper end of the slide rod, an upper ball groove is sleeved on the outer side of the upper ball, and an upper screw seat is fixedly connected to the upper side of the upper ball groove. The upper screw seat is screwed and installed at the bottom of the sewage pump connection base.

[0009] Furthermore, a lower ball is fixedly connected to the lower end of the sleeve, a lower ball groove is sleeved on the outer side of the lower ball, and a lower screw seat is fixedly connected to the bottom of the lower ball groove. The lower screw seat is screwed onto the upper side of the mounting base.

[0010] Furthermore, mounting holes are provided at the four corners of the mounting base.

[0011] Furthermore, the sewage pump connecting base is provided with four sets of screw-in elongated holes, and the screw-in elongated holes are distributed at equal angles.

[0012] Furthermore, raised ribs are evenly distributed on the outer wall of the thick rubber ball.

[0013] Furthermore, both the rubber valve plate and the thick rubber ball are made of silicone rubber.

[0014] Furthermore, the spring is made of durable stainless steel.

[0015] Compared with related technologies, the earthquake-resistant sewage pump installation mechanism proposed in this utility model has the following beneficial effects:

[0016] In this utility model, an anti-vibration sewage pump installation mechanism is provided. The vibration damping mechanism has a ball groove and rolling ball connection at both ends, which enables the vibration damping mechanism to reduce vibration in all directions. The vibration damping mechanism utilizes the inertia of heavy oil, the adaptive contraction and deformation of thick rubber balls, the adaptive deformation of springs, and the abutting friction between the rubber valve plate and the inner wall of the sleeve to improve the vibration damping effect of the entire mechanism. Compared with traditional vibration dampers, it has a significant improvement in vibration damping performance, enabling the sewage pump installed on this device to operate stably, reducing the impact of vibration, and improving the service life of the sewage pump.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Reference Figures 1-4 An anti-vibration sewage pump installation mechanism includes a mounting base 1, a sewage pump connecting base 3 located directly above the mounting base 1, and four sets of shock-absorbing mechanisms 5 located at the bottom of the sewage pump connecting base 3. The shock-absorbing mechanism 5 includes a sliding rod 54 and a sleeve 55. A rubber valve plate 511 is fixedly installed at the bottom of the sliding rod 54. The rubber valve plate 511 slides against the bottom of the sleeve 55. A spring 512 is fixedly connected between the bottom of the rubber valve plate 511 and the bottom of the sleeve 55. A through-hole 513 is opened on the bottom side wall of the sleeve 55. A thick rubber ball 59 is fixedly installed inside the through-hole 513. The sleeve 55 and the thick rubber ball 59 are filled with heavy oil.

[0024] In this method, both the rubber valve plate 511 and the thick rubber ball 59 are made of silicone rubber.

[0025] Through the above-mentioned configuration, silicone rubber is a polymer material with excellent comprehensive performance. It has excellent high and low temperature resistance, outstanding elastic recovery ability and tensile strength, as well as excellent electrical insulation, physiological inertness and biocompatibility. It also exhibits good stability against ozone, ultraviolet rays, humid environments and chemical media (such as acids, alkalis and solvents), thereby improving the service life of rubber valve plate 511 and thick rubber ball 59.

[0026] In this method, spring 512 is made of durable stainless steel.

[0027] The above-described design improves the durability of spring 512.

[0028] In this configuration, an upper ball bearing 53 is fixedly connected to the upper end of the slide rod 54. An upper ball groove 52 is sleeved on the outer side of the upper ball bearing 53. An upper screw seat 51 is fixedly connected to the upper side of the upper ball groove 52. The upper screw seat 51 is screwed onto the bottom of the sewage pump connecting base 3. A lower ball bearing 56 is fixedly connected to the lower end of the sleeve 55. A lower ball groove 57 is sleeved on the outer side of the lower ball bearing 56. A lower screw seat 58 is fixedly connected to the bottom of the lower ball groove 57. The lower screw seat 58 is screwed onto the upper side of the mounting base 1.

[0029] With the above-mentioned configuration, both the upper and lower ends of the damping mechanism 5 are connected by ball grooves and rolling balls, thus having multi-dimensional angular rotational freedom, enabling it to weaken vibrations in multiple directions and improve the overall damping effect.

[0030] In this method, mounting holes 2 are provided at the four corners of the mounting base 1.

[0031] The above-described configuration facilitates the installation of the mounting base 1 onto the relevant structure via the mounting holes 2.

[0032] In this method, the sewage pump connecting base 3 is provided with four sets of screw-in elongated holes 4, and the screw-in elongated holes 4 are distributed at equal angles.

[0033] With the above-described configuration, the screw-in elongated hole 4 allows for the screw-in installation of sewage pumps of different specifications on the sewage pump connecting base 3.

[0034] In this method, raised ribs 510 are evenly distributed on the outer wall of the thick rubber ball 59.

[0035] By setting up the above-mentioned structure, the protruding ribs 510 improve the overall structural strength of the thick rubber ball 59, thereby increasing its comprehensive elastic tension.

[0036] The working principle of the earthquake-resistant sewage pump installation mechanism provided by this utility model is as follows:

[0037] When the sewage pump vibrates during operation, the vibration is first transmitted to the sewage pump connecting base 3, and then distributed to the four sets of damping mechanisms 5. In the damping mechanism 5, since the upper end of the slide rod 54 is connected to the upper ball groove 52 through the upper ball 53, and the lower end of the sleeve 55 is connected to the lower ball groove 57 through the lower ball 56, this structure allows the damping mechanism 5 to flexibly cope with multi-directional vibrations.

[0038] For vertical vibrations, the slide bar 54 will drive the rubber valve plate 511 to slide up and down inside the sleeve 55. When the rubber valve plate 511 moves downward, it will compress the spring 512. The elastic deformation of the spring 512 can absorb some of the vibration energy. At the same time, the heavy oil inside the sleeve 55 will be squeezed and flow into the thick rubber ball 59 through the port 513, causing the thick rubber ball 59 to expand. Its elastic deformation further buffers the vibration. When the rubber valve plate 511 moves upward, the spring 512 returns to its original position, and the heavy oil inside the thick rubber ball 59 flows back to the sleeve 55. The inertia of the heavy oil can slow down the movement speed, and the friction between the rubber valve plate 511 and the inner wall of the sleeve 55 will also consume some of the vibration energy.

[0039] To mitigate vibrations in both the horizontal and torsional directions, the upper rolling ball 53 rolls within the upper ball groove 52, and the lower rolling ball 56 rolls within the lower ball groove 57, which can dissipate some of the vibrations. At the same time, the thick rubber ball 59 will undergo adaptive shrinkage deformation due to uneven force, which, combined with the flow of heavy oil, further weakens the vibration energy in both the horizontal and torsional directions.

[0040] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
