Description

Technical Field

[0001] The utility model belongs to the technical field of water injection devices, in particular to a water injection device for water conservancy project tests. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. Water is a valuable resource that is indispensable to human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods and waterlogging disasters, and regulate and distribute water to meet people's needs for water resources in life and production. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, ferries, rafts, fishways, etc. to achieve their goals.

[0003] The existing water injection device has vibration when being used for testing. When the vibration frequency is high, the water injector will be damaged, thus affecting the progress of the water injection test. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a water injection device for water conservancy project testing, and the technical solution adopted is as follows:

[0005] A water injection device for water conservancy project testing includes a water injector and a base below, wherein the four corners below the water injector are equipped with supporting feet, corresponding positions of the base are provided with mounting grooves for the supporting feet to be placed in, and rubber pads are provided at the connection between the supporting feet and the water injector and at the connection between the supporting feet and the base; the lower surface of the water injector is provided with a plurality of thread holes for installing a pressure rod, rubber sleeves are respectively installed inside the base at positions corresponding to the pressure rod below the water injector, and a pillar in contact with the lower end of the pressure rod is inserted inside the rubber sleeve.

[0006] Furthermore, the lower end of the pressure rod is arc-shaped, and the upper end of the pressure rod is a screw that can be connected to the thread hole. In this way, a corresponding number of pressure rods can be installed according to usage requirements.

[0007] Furthermore, the upper end of the pillar is changed to a cylindrical shape, and an arc groove matching the shape of the lower end of the pressure rod is opened on the upper surface of the cylinder; a spring for supporting the pillar to rise upward is installed at the lower end of the cylinder in the pillar, so that the pillar and the pressure rod are in close contact to achieve the effect of absorbing vibration.

[0008] Furthermore, a plurality of studs fixed on the base are provided in the installation groove. After the supporting foot is placed in the installation groove, the studs pass through the top of the supporting foot and are connected with nuts.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] The utility model can control the distance between the pressure rod and the base, adjust the contact strength between the pressure rod and the support and the fixing strength between the water injector and the base by adjusting the tightness of the nut. In actual use, it can be adjusted according to the vibration frequency of the water injector to achieve a better vibration reduction effect.

[0011] There is no direct contact between the water injector and the base of the utility model. Rubber pads are provided at the connection between the support leg and the water injector and at the connection between the support leg and the base. The lower end of the support leg is inserted into a rubber sleeve embedded in the base. This contact mode is combined with the pressure rod and the support leg to achieve multi-point vibration reduction, which can increase the service life of the water injector and ensure the stable operation of the water injection device during testing.

[0018] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be described clearly and completely below. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0019] As attached Figure 1-4 shown.

[0020] A water injection device for water conservancy project testing includes a water injector 2 and a base 1 below, wherein legs 3 are installed at the four corners below the water injector 2, and mounting grooves 11 for placing the legs 3 are provided at corresponding positions of the base 1, and a plurality of studs 12 fixed to the base 1 are provided in the mounting grooves 11. After the legs 3 are placed in the mounting grooves 11, the studs 12 in the mounting grooves 11 pass through the legs 3, and the legs 3 are fixedly installed by nuts 31; a plurality of thread holes 21 for installing a pressure rod 6 are opened on the lower surface of the water injector 2, the lower end of the pressure rod 6 is arc-shaped, and the upper end of the pressure rod 6 is a screw that can be connected to the thread holes 21.

[0021] A rubber sleeve 5 is installed inside the base 1 at the position corresponding to the pressure rod 6 below the water injector 2. A pillar 51 is inserted inside the rubber sleeve 5. The upper end of the pillar 51 is a cylinder. An arc groove matching the shape of the lower end of the pressure rod 6 is opened on the upper surface of the cylinder. A spring 52 for supporting the pillar 51 to rise upward is installed at the lower end of the cylinder in the pillar 51.

[0022] The working principle is as follows: first, install the support foot 3 and the pressure rod 6 below the water injector 2, install the rubber sleeve 5 above the base 1 and insert the support 51 into the rubber sleeve 5, and set a spring 52 that can support the support 51, and then fix the water injector 2 above the base 1 through the cooperation between the stud 12 and the nut 31.

[0023] After the water injector 2 is placed on the base 1, the pressure rod 6 at the bottom of the water injector 2 contacts the support 5, and the spring 52 makes the combination more tightly.
