Description

Technical Field

[0001] The present application relates to the technical field of devices using the water hammer principle, and in particular to a water energy water extraction device. Background Art

[0002] With the progress of society and the recognition of the limitations of petrochemical energy applications, people are paying more and more attention to various equipment that directly convert natural forces into power. As a pumping equipment that can operate effectively without secondary energy such as electricity, water energy water pumping equipment is an ideal natural force conversion equipment. Water energy water pumping equipment is an advanced water pumping device that uses flowing water as power, produces water hammer effect through mechanical action, and converts low head energy into high head energy.

[0003] Water energy extraction equipment primarily consists of six components: an inlet pipe, a pump, a drain valve, a center valve, a pressure tank, and an outlet pipe. When water flowing down the inlet pipe reaches the drain valve (a deadweight-loaded valve), the force of the water flow (sufficient as long as the flow rate is high enough) causes the valve to close rapidly. However, if the water suddenly stops flowing, its kinetic energy is converted into pressure energy. This increases the pressure within the pipe, pushing open the center valve. Some water enters the pressure tank and rises along the outlet pipe to a certain height. Subsequently, as the pressure in the inlet pipe decreases, the drain valve automatically drops under the action of the deadweight, returning to its open state. Simultaneously, the compressed air in the pressure tank forces the center valve to close, and the entire process repeats.

[0004] Existing water energy water pumping equipment has poor impurity removal effect or blocks water flow during impurity removal, resulting in poor operation effect of the water energy water pumping equipment. Summary of the Invention

[0025] The present application is described in detail below with reference to the accompanying drawings and optional embodiments.

[0026] like Figure 1 As shown, as an embodiment of the present application, a water energy water extraction equipment 100 is disclosed, including a filter element 101, wherein the filter element 101 is arranged at the water inlet 102 of the water energy water extraction equipment 100, and the filter element 101 is respectively installed and connected to the water inlet 102 of the water energy water extraction equipment 100 and the external water inlet pipe 103; the filter element 101 includes a tubular shell 104 and a conical filter screen 105, and the two ends of the shell 104 are respectively installed and connected to the water inlet 102 of the water energy water extraction equipment 100 and the external water inlet pipe 103, and the filter screen 105 is arranged on the side of the shell 104 close to the external water inlet pipe 103, and the conical tip of the filter screen 105 faces the side of the external water inlet pipe 103.

[0027] The water energy water extraction equipment 100 disclosed in this solution is provided with a filter 101 at the water inlet 102. The filter 101 includes a tubular shell 104 and a filter screen 105. The two ends of the shell 104 are respectively connected to the water inlet 102 of the water energy water extraction equipment 100 and the external water inlet pipe 103. The filter screen 105 is arranged on the side of the shell 104 close to the external water inlet pipe 103. The filter 101 is conical, and the conical tip of the filter screen 105 faces the external water inlet pipe 103. In this way, the water energy water extraction equipment 100 is not affected by the water inlet pipe 103. When water is introduced into the water inlet 102 of the water-lifting equipment 100, impurities mixed in the water will be intercepted by the filter 105. At the same time, under the action of the water flow, the impurities will accumulate from the edge of the middle phase along the conical filter 105. In this way, the impurities accumulated at the edge of the filter 105 have less obstruction to the water flow, while the existing flat mesh filter 105 will accumulate impurities against the water flow, which has a greater obstruction to the water flow. Therefore, the filter element 101 of this scheme significantly improves the operating effect of the water energy water-lifting equipment 100 compared with the existing technology.

[0028] The shell 104 is an integrally formed structure, and the diameter of the end of the shell 104 connected to the external water inlet pipe 103 is larger than the diameter of the end of the shell 104 connected to the water inlet 102 of the water energy water extraction equipment 100, and the cross-section of the shell 104 through the central axis is in the shape of a "convex" character, and the filter 105 is installed on the inner side of the shell 104 with a larger diameter. In this solution, the integrally formed shell 104 can provide better structural stability and can be used under the impact of strong water flow. The shell 104 is designed to be in a "convex" shape, and the filter 105 is installed on the inner side of the shell 104 with a larger diameter. In actual use, when impurities in the water flow are guided to the edge by the filter 105, they can be blocked by the side wall of the shell 104. When cleaning is required, only the shell 104 needs to be cleaned.

[0029] In order to stabilize the water flow, in this solution, the diameter of the connection end between the shell 104 and the water inlet 102 of the water energy water extraction equipment 100 is equal to the diameter of the water inlet 102 of the water energy water extraction equipment 100 .

[0030] Specifically, a first switch 106 for controlling water is provided at the water inlet 102 end of the water energy water extraction equipment 100, and the shell 104 includes a first shell 108 and a second shell 109. The first shell 108 is detachably connected to the external water inlet pipe 103, and the second shell 109 is detachably connected to the water inlet 102 of the water energy water extraction equipment 100. The filter net 105 is arranged between the first shell 108 and the second shell 109. The first shell 108 and the second shell 109 are detachably connected, and the first shell 108 is provided with a second switch 107 for controlling water. Considering that if excessive impurities accumulate, it will increase the obstruction to water flow, in order to facilitate the cleaning of impurities, the filter element 101 disclosed in this solution includes a first shell 108 and a second shell 109. The first shell 108 and the second shell 109 are connected in a detachable manner. In this embodiment, they are connected by bolts and nuts. Then the first shell 108 is detachably connected to the external water inlet pipe 103, specifically also connected by bolts and nuts. The second shell 109 is detachably connected to the water inlet 102 of the water energy water extraction equipment 100, specifically also connected by bolts and nuts. At the same time, the water inlet 102 end of the water energy water extraction equipment 100 is provided with a first switch 106 for controlling water, and the first shell 108 is provided with a second switch 107 for controlling water. In this way, when the first switch 106 and the second switch 107 are controlled to be closed, the second shell 109 can be removed. Because the filter screen 105 is arranged between the first shell 108 and the second shell 109, the filter screen 105 can be removed, the impurities can be cleaned, and then it can be reinstalled and continued to be used normally. The filter screen 105 in this embodiment can be fixed to the second shell 109 by screws, or the filter screen 105 can be clamped between the first shell 108 and the second shell 109 by the tightening force between the two.

[0031] Furthermore, the filter 105 is made of a hard plastic material. Existing technology allows the use of hard plastic to manufacture various components, resulting in excellent strength and wear resistance, and low cost. Of course, the filter 105 can also be made of the same material as the water inlet pipe 103 of the water energy extraction device 100. If the liquid being used has electrolyte properties, to prevent chemical battery phenomena, this solution uses the same material for the filter 105 and the water inlet pipe 103 of the water energy extraction device 100.

[0032] More specifically, the present solution discloses that the filter screen 105 is provided with a plurality of filter holes 110, and the filter holes 110 are gradually densely distributed from the conical tip toward the edge. Considering that the impurities intercepted by the filter screen 105 will accumulate at the edge of the filter screen 105, in order to prevent the impurities from being continuously flushed by the water flow and being washed into the water energy water extraction equipment 100, the present solution gradually densely distributes the filter holes 110 on the filter screen 105 from the conical tip toward the edge. In this way, the denser filter holes 110 can play a good blocking role for the impurities accumulated at the edge of the filter screen 105, and can effectively prevent the impurities that have been blocked from being washed into the water energy water extraction equipment 100 by the water flow. Of course, the filter holes 110 on the filter screen 105 can also be evenly arranged more densely.

[0033] like Figure 2 As shown, the present application also discloses a method for installing a water energy extraction device 100, wherein the water energy extraction device 100 includes a filter element 101, the filter element 101 is arranged at the water inlet 102 of the water energy extraction device 100, and the filter element 101 is respectively installed and connected to the water inlet 102 of the water energy extraction device 100 and the external water inlet pipe 103; the filter element 101 includes a tubular shell 104 and a conical filter screen 105, the two ends of the shell 104 are respectively installed and connected to the water inlet 102 of the water energy extraction device 100 and the external water inlet pipe 103, the filter screen 105 is arranged on the side of the shell 104 close to the external water inlet pipe 103, and the conical tip of the filter screen 105 faces the external water inlet pipe 103; the installation method of the water energy extraction device 100 includes the following steps:

[0034] S1: Install the conical filter screen on one end of the housing connected to the external water inlet pipe, with the conical tip of the filter screen facing the external water inlet pipe;

[0035] S2: Connecting the housing on which the filter is mounted to the external water inlet pipe;

[0036] S3: Connect the other end of the shell to the water inlet of the water energy water extraction equipment.

[0037] It should be noted that the limitations on the various steps involved in this application do not limit the order of the steps without affecting the implementation of the specific scheme. The steps written in front can be executed first, later, or even simultaneously. As long as this application can be implemented, it should be deemed to fall within the scope of protection of this application.

[0038] The above content is a further detailed description of the present application in conjunction with specific optional implementation methods, and the specific implementation of the present application cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, they can make several simple deductions or substitutions without departing from the concept of the present application, which should be considered to fall within the scope of protection of the present application.
