[0020] The following is an explanation of the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0021] The following is combined with Figure 1-3 The utility model is described in further detail.

[0022] The utility model embodiment discloses a pitch transmitter dynamic water-tight test box. Figure 1-3The pitch transmitter dynamic water sealing test box includes a bottom box 1 for installation on the simulation equipment and a water cylinder assembly 2 arranged on the bottom box 1 for adjusting the water level. The pitch transmitter is installed inside the bottom box 1. Two mounting brackets 3 for installing different types of pitch transmitters are arranged on the side wall of the bottom box 1. By installing two different types of pitch transmitters on the two mounting brackets 3, the working condition simulation test of two different types of pitch transmitters can be completed at one time, which can shorten the test time by half. Different types of pitch transmitter mounting brackets can be made to match different types of pitch transmitters with the test water tank, which meets the functional requirements of one machine for multiple uses and maximizes the value of the test water tank. During the experiment, the external power input is provided to the pitch transmitter shaft, which drives the pitch transmitter shaft to complete the periodic angle rotation, transmits the signal through the cable, and converts it into test data through the circuit board, thereby simulating the working condition of the reciprocating motion of the cylinder piston on the ship.

[0023] In this embodiment, the mounting bracket 3 includes an internal flange 31 arranged on the inner wall of the bottom box 1 for mounting the pitch transmitter and an external flange 32 arranged on the outer wall of the bottom box 1 and connected to the internal flange 31. The internal flange 31 and the external flange 32 form a sealing structure. The internal flange 31 and the external flange 32 can pass cables through the stuffing box. The cables are connected to the circuit board and the test data can be recorded. Through the connection between the internal flange 31 and the external flange 32, the interior of the entire bottom box 1 becomes a closed test space. After the preparation is completed according to the technical requirements, the corresponding tests are carried out and the data is recorded for analysis to test the waterproofness and reliability of the product.

After the door cover 4 is installed on the bottom box 1, the bottom box 1 can be locked to achieve a sealing effect.

[0027] In this embodiment, the door cover 4 is provided with a reinforcing beam 41 for reinforcing its own strength. The reinforcing beam 41 is a channel steel and two are provided, which are horizontally placed on the door cover 4 to enhance the overall strength of the door cover 4 .

[0028] In this embodiment, an internal support 11 is provided on the inner wall of the bottom box 1 for increasing its own strength. The internal support 11 is a steel plate covering the inner wall of the bottom box 1 and is used to increase the overall strength of the bottom box 1 .

[0029] In this embodiment, a bottom support 12 is provided at the bottom of the bottom box 1. The bottom support 12 is two channel steels and is used to install the bottom box 1 on the tooling experimental equipment.
